Our Solutions

We provide our customers with standards-based and custom advanced embedded solutions that enable them to focus their resources and development efforts on
their key areas of differentiation and allow them to provide higher value systems with a time-to-market advantage and a lower total cost.

Key benefits of our solutions include:

Leading, high-performance technology. We have been the first to market with many
technological advancements such as the industrys first 10-Gigabit common managed platform, and we are a leader in areas such as IP conferencing and COM Express new product development. Our design capabilities extend to CPUs, NPUs, digital
signal processing and integrated software managed platforms, such as media and application servers, as well as many other areas.

Deep
pool of technical resources. Our research and development staff has extensive experience in designing embedded hardware and software solutions. Our customers benefit from the broad array of standards-based solutions that our research and
development staff continues to develop and support, as well as our staffs experience in designing perfect fit solutions for our customers.

Reduced time to market. We offer standards-based, ready-made solutions such as ATCA-based solutions for the communications networking market and COM Express solutions for the commercial market. These standards-based solutions
combined with our strong technical resources provide our OEM customers with more flexibility and reduced time-to-market than if they developed these solutions internally.

Broad portfolio of embedded solution products. Our product lines include a large portfolio of embedded solutions, integrated platforms and application-ready systems. Our product portfolio allows us to address a
range of customer requirements and applications. We believe that over time many of our customers will increasingly rely on a smaller set of vendors who can address a broader set of their embedded solution needs.

Our Strategy

Build market leadership in
standards-based advanced embedded solutions in our target markets. We believe this strategy enables our customers to focus their resources and development efforts on their key areas of competency allowing them to provide higher value systems
with a time-to-market advantage and a lower total cost. We are currently one of the leading vendors in ATCA, IP Media Servers as well as COM Express embedded solutions. We intend to continue to invest significant research and development and sales
and marketing resources to build our presence in these market segments.

Develop our offering of higher value platform solutions.
Historically, the majority of our revenues have been from the sale of stand-alone boards or blades. While we will continue to focus on these products, we have spent considerable resources developing application-ready platform solutions that
incorporate complete hardware systems as well as embedded software developed by us or third parties. These platforms provide an additional revenue opportunity for us, and we believe revenues from these products have the potential to generate higher
average selling prices and higher gross margins than those provided from the sale of boards or blades alone.

Expand our global customer
base. We continue to expand the number of customers that we work with, particularly as more customers become aware of the benefits of standards-based embedded solutions. Our global reach allows us to market our solutions to most leading system
vendors in our target markets. In addition, our acquisitions of Convedia Corporation (Convedia) and certain assets of the Modular Communications Platform Division (MCPD) business from Intel Corporation (Intel)
provide us access to additional customers to whom we intend to market our full product line.

##### Table of Contents

Explore new partnerships and strategic
acquisitions as a means to build leadership in our target markets. We continue to investigate partnerships and strategic relationships which can expand the number of solutions we offer and increase our market reach. We also continue to evaluate
potential acquisition opportunities to acquire new capabilities, which can help us achieve our strategic goals. For example, in the last two years, we acquired Convedia®, a closely-held
vendor of IP media servers, and certain assets of the Intel MCPD business, which included ATCA and compact peripheral component interconnect (PCI) product lines.

Products

We design and manufacture a broad range of products at different levels of integration:

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

Our products
fall into two different categories: standards-based solutions and perfect fit (custom) solutions.

Standards-based Solutions. As a Premier Member of the Intel® Embedded and Communications Alliance, and as a long-time member of the PCI Industrial
Computer Manufacturers Group (PICMG), SCOPE Alliance and the Service Availability (SA) Forum standards bodies, we believe that we continue to play a leading role in the development and deployment of system architectural
standards that are most relevant to our markets. In the IP communications market we believe that we continue to play a leading role in the development and deployment of media server and Multimedia Resource Function (MRF) standards
through our membership in the Third-Generation Partnership Project (3GPP) and our long-term contributions to the Internet Engineering Task Force (IETF).

Beginning in 2004 we shifted our product development investment from predominantly one-off custom-designed products (perfect fit solutions)
to standards-based, re-usable platforms and systems (standards-based solutions). We believe standards-based solutions provide our customers a number of fundamental benefits. First,

by using ready-made solutions rather than ground-start custom-designs, our customers can achieve significantly shorter product development intervals and
faster time-to-market. Second, we believe our customers can achieve a lower total cost by using solutions that are leveraged across multiple applications rather than a single-use proprietary solution. The benefit to RadiSys is that by offering
standards-based solutions, we believe we have the opportunity to address a wider range of new market opportunities than with one-off, custom-designs. We believe this ability to reuse designs gives us more leverage and makes our business and
investment model more scalable. Finally, we believe this standards-based model will allow us to provide more integrated and higher value solutions to our customers than we have typically delivered under a custom-design model. In many cases RadiSys
will optimize its standard products to best suite the needs of a particular customer or application. This has the dual benefit of giving customers a higher value solution as well as making RadiSys a better choice for the application over the
longer term. These higher value solutions should provide more product content and drive higher average selling prices and therefore more total revenue opportunity for our products.

We intend to increasingly focus our development efforts on moving further up the software stack, positioning us to provide more complete
application-ready platforms and more value for our customers. We believe that application-ready modular solutions such as ATCA platforms and Media Servers will grow to become an attractive market to RadiSys. The success of our new ATCA projects is
tied to future deployment of wireless voice, wireless data and Voice over Internet Protocol (VoIP) applications by our customers. Likewise the success of our Media Servers is tied to the future deployment of IP Multimedia Subsystems
(IMS) and IP networks.

We believe that ATCA and Media Servers will continue to become more prevalent in implementing network
equipment. However, history has shown us that rates of adoption in these markets can be slower than projected. For RadiSys, this is predominately a new market opportunity that had not existed in a meaningful way for us prior to 2007, and only a
limited number of equipment makers had used merchant-supplied, standards-based modular platforms. Based on our interactions with customers and recent results, we believe this model will become more widely adopted as network equipment makers strive
to bring more products to market faster and with lower design and product costs.

We have introduced or announced the following
standards-based solutions products:

Promentum®. Our Promentum® ATCA family includes a fully integrated application ready platform as well as a set of modular building blocks all configurable for a
wide variety of applications. Going beyond simple building blocks, our ATCA strategy delivers a common managed platform for network element and dataplane applications, which offers a significant benefit to our customers. Utilizing the same managed
platform for a variety of applications, Telecom Equipment Manufactures (TEMs) can reduce overall development time and significantly reduce development, lifecycle and equipment costs.

The Promentum® SYS-6010 is the
industrys first ATCA 10G managed platform. The SYS-6010 is a fully integrated and validated managed platform designed to address high speed I/O and bandwidth intensive traffic-bearing applications. This platform is designed to be implemented
in a flexible and reliable architecture complete with comprehensive system management. The Promentum® ATCA building blocks are implemented in a modular fashion with seamless
interoperability.

During the first half of 2008, we introduced two new products in
our Promentum® ATCA product portfolio. First was the Promentum® ATCA-4310, a 10G ATCA single-slot processor blade. We believe
this product provides enhanced features for compute-intensive applications where transaction and subscriber load can increase dramatically in short intervals, such as IMS, Internet Protocol Television (IPTV) and Wireless Control Plan
based applications. The second was the Promentum® ATCA-7220 Dual OCTEON PLUS Packet Processing Module, the industrys first blade to enable highest density of Gigabit Ethernet
interfaces in a single slot with significantly higher processing power and bandwidth access when compared to other platforms available today.

During the second quarter of 2008, we received the 2007 Communications Solutions Product of the Year
Award for the Promentum ATCA MCPBL0050 CPU blade and the Promentum ATCA 7220 CPU blade with smart front-end architecture. The Communications Solutions Product of the Year Awards recognize the most innovative products that facilitate voice, data and
video communications, or combinations thereof.

During the third quarter of 2008, we announced two new application ready platforms. The
first is the SYS-6016 platform, which is a fully integrated high-capacity 16-slot solution that provides the maximum number of billable application slots in an ATCA carrier-grade platform, and delivers industry-leading 10-Gigabit switching, packet
processing, and media processing capabilities. The second is the SYS-6002, which is a low-profile 2-slot integrated platform that provides a compact cost-effective solution ideally suited for an array of specialized appliances such as sophisticated
security and traffic handling applications. The SYS-6016 increases payload capacity for maximum subscriber density while the SYS-6002 addresses lower-density subscriber areas. In addition, RadiSys launched a lab for use by global ecosystem partners
and customers so that they may remotely perform validation, testing, and demonstrations of their unique solutions on our ATCA systems.

Convedia® Media Servers
(CMS). Our line of market leading IP media server products enables service innovation and differentiation by providing powerful, reusable and highly scalable multimedia processing platforms for the VoIP and IMS telecommunication and
enterprise markets. Together with products by our solution partners, the CMS family supports the next generation of feature rich, application-ready, high-value services that combine the best of the Internet and telecommunications worlds.

The CMS family consolidates the functions of traditional announcement servers, interactive voice response units, audio and video conference bridges,
messaging platforms and speech platforms into a single, multi-service, open standards-compliant solution for network and enhanced services media processing. Our CMS share identical control interfaces, media processing features and management
capabilities. The many features and benefits of our CMS allow our customers to increase revenues through delivery of new and innovative services, while reducing capital and ongoing operational costs. Our CMS-1000 and CMS-6000 media servers have been
successfully deployed around the world. During 2008 we began deployment of the next generation of media servers, the CMS-3000 and CMS-9000.

In the second quarter of 2008, we announced the addition of continuous presence (CP) capabilities in our CMS family. More specifically, our new CP video conferencing mode will support multiple real-time video streams within a
unified multi-pane display and deliver an immersive video experience for desktop conferencing users. This new capability will benefit our customers who wish to add feature-rich video conferencing capabilities to their communications
solutions.

In addition, in the second quarter of 2008 we announced that our CMS family now supports automatic speech recognition
(ASR), or converting human speech to computer data, and text-to-speech (TTS) capabilities in multiple languages for IP contact center application developers and service providers. This new capability will not only allow our
customers to accelerate the introduction of new services, but will also competitively differentiate their products in next-generation IP contact centers.

During the third quarter of 2008, we announced a rich feature set targeted to the contact centers with the RadiSys market-leading IP media server platform. The Convedia product family has real-time audio, video, and
new embedded fax media processing capabilities that provide a common, feature-rich platform that fulfills next-generation contact center business requirements.

Procelerant. Our Procelerant CE blades and boards are designed for embedded applications that require a standard processor and memory subsystem, but also modular flexibility to retain key
design level IP on a separate carrier board. Procelerant CE products are based on modular computing solutions. COM Express is a standard that provides a bridge from legacy interfaces such as PCI and integrated drive electronics
(IDE) to new serial differential signaling technologies such as PCI Express, Serial ATA, USB 2.0, LVDS, and Serial

DVO. Because they are modular and standards-based, our COM Express products help equipment manufacturers shorten their time to market and reduce development
costs. By making processor, chipset and memory modular and independent of the rest of the system design, manufacturers can focus engineering resources on developing differentiating features and avoid the design churn that comes with implementing new
processor generations.

Also in the Procelerantproduct family are our embedded servers that specialize in meeting the needs
of specific applications that are designed to be the brains of a larger integrated system. Examples of systems that incorporate embedded servers include medical imaging systems, high performance test and measurement instruments, automated industrial
equipment, telecommunications appliances, military imaging and signal processing systems, and casino gaming machines.

During the first half of 2008, we introduced two new products in our Procelerant
portfolio. First was the Procelerant Quad-core server, the industrys first embedded server to incorporate the latest Intel® Quad-core Xeon® processors. Intended for medical and other imaging, test and measurement, and other digital signal processing applications, the Procelerant RMS420-5000XSL Quad-core server supports superior image
processing at a higher resolution and with greater speed compared to previous embedded servers. Second was the Procelerant CE945GM2A COM Express module that targets value-priced industrial automation, gaming and test and measurement
applications. The Procelerant CE945GM2A replaces older ETX technology at a comparable price point, enabling high-speed serial interface options such as PCI Express, Serial ATA (SATA) and gigabit ethernet.

During the second quarter of 2008, we introduced CEGM45, with the Intel® Core 2 Duo processor T9400 for high-performance portable implementations in medical and machine imaging, test and measurement, and communications. This product is early to market and
brings lower power and increased processing capability.

During the third quarter of 2008, we announced the availability of four new COM
Express modules all powered by Intel Core 2 Duo Processor technology and the Mobile Intel GS45/GM45 Express chipsets. The new compact COMs are ideal for developers designing portable devices for such applications as medical and machine imaging that
mandate processing performance, large file transfers, high-throughput communications and low power.

During the fourth quarter of 2008, the
Procelerant RMS420 image processing server began shipping in production to two of our Tier 1 medical imaging customers. The Procelerant RMS420 embedded server combines very high compute performance with dual
PCI-Express (PCIe) x16 slots (x8 electrical) for high performance graphics and/or co-processor cards. This combination is ideally suited for applications such as medical and military imaging, signal processing, 3D and 4D graphics display and test
and measurement systems.

During the fourth quarter of 2008, we also announced that
we developed, with industry consortium Embedded4You, a powerful multi-core, application-ready platform for industrial automation. The demonstration of the platform showcases the integration of general purpose Microsoft® Windows® and RadiSys Microware® OS-9® real time operating system running concurrently on a RadiSys COM Express module. This hybrid approach allows individual systems to merge onto a single platform to reduce hardware cost, reuse available software and improve system performance.
This approach also allows OS-9 to guarantee high real-time reliability, stability and system response time with zero impact on other applications running on the system.

Perfect Fit Solutions. Our perfect fit solutions are products tailored or customized to meet specific customer or application requirements. These solutions range from modifications of standard or existing
products to complete development and supply of customized solutions. We draw on our experience and large design library to create products with varying degrees of customization. We will continue to invest a portion of our resources in perfect fit
solutions as these opportunities are an integral part of our business model and leverage our existing know-how. We also believe that our customers will continue to require and value some degree of customization of our standards-based platforms for
some of their specific applications.

Segments

RadiSys is one operating segment as determined by the way that management makes operating decisions and assesses RadiSys financial performance. See Note 20 of the Notes to the Consolidated Financial Statements for segment information.

Competition

We have three different
types of competitors:



| |  |  | Our target customersOur most significant competition is from our own customers and potential customers who choose to remain vertically integrated and
continue to fully design and supply all or most of their own platforms, modules and/or sub-systems. However, we believe system makers are moving away from this proprietary mode of system development and supply.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Platform ProvidersOur competitors in the platform product space include Emerson Network Power, HP, IBM, and Sun Microsystems. In addition, we face
competition in the media server market from AudioCodes, Dialogic and Movius.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Board providersOur competitors in the board product space include ADLink Technologies, Advantech Co., Continuous Computing, Emerson Network Power and
Kontron AG.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------

We believe that our system level architecture and design expertise, coupled with our broad technology
portfolio and flexibility in working intimately with system makers, will enable us to differentiate our products against our competition. We believe our rapid design cycles and standards-based solutions coupled with our global presence will provide
customers with a time to market advantage at a lower total cost.

Customers

Our customers include many leading system makers in a variety of end markets. Examples of these customers include: Agilent Technologies, Alcatel Lucent,
Arrow Electronics, Aspect Telecom, Avaya, Bigband Networks, British Telecom, Cisco Systems, Comverse Network Systems (Comverse)- a division of Comverse Technology, Danaher, Fujitsu, G.E. Healthcare, Huawei Technologies Co., IBM, IP
Access, Italtel, Kineto Wireless, Miltope, Mindray, NEC, Nokia Siemens Networks, Nortel Networks (Nortel), Philips Healthcare, Siemens Medical, and Universal Instruments, West Corporation, and ZTE.

Our five largest customers, accounting for approximately 59.7% of revenues in 2008 are listed below with an example of the type of application which
incorporates RadiSys products:



|                      |  |                                                                            
|--------------------- |  | ---------------------------------------------------------------------------
|Customer              |  | Application                                                                
|Agilent               |  | Network and logic analyzers along with other test and measurement equipment
|Danaher               |  | Scopes, logic analyzers, network probes and monitoring equipment           
|Fujitsu               |  | 3G wireless infrastructure equipment                                       
|Nokia Siemens Network |  | 2, 2.5, and 3G wireless infrastructure equipment                           
|Philips Healthcare    |  | Cardiovascular, surgical, and medical imaging equipment                    

Nokia Siemens Networks was our largest customer in 2008 accounting for 43.5% of total 2008
revenues.

Technology, Research, Development and Engineering

We believe that our technology, research, development and engineering (R&D) expertise represents an important competitive advantage. Our R&D staff consisted of 281 engineers and technicians as of
January 30, 2009. We currently have design centers located in the U.S, Canada, China and Malaysia.



7



---

##### Table of Contents

A majority of our R&D efforts are focused on the development of sophisticated standards-based
products targeted at a wide variety of applications. This is an important part of our strategy to provide a broader set of products and building blocks, which allows deployment of flexible solutions leveraged off of reusable designs and commercially
available components. We believe this will result in significant savings in development time and investment for our customers and will increase the number of applications into which RadiSys solutions can be incorporated. In addition, we are
increasingly combining our standards-based products to create more integrated and more complex hardware and software based systems.

We
also focus on the development of custom solutions for our customers, where existing functional building blocks are tailored to meet the customers specific needs. For these programs, our engineering team works closely with the customers
engineering team to architect, develop and deliver solutions that meet their specific requirements using RadiSys functional building blocks. We engage in close and frequent communications during the design and supply process, allowing us to
operate as a virtual division within a customers organization. We believe our in-depth understanding of embedded systems and technology provides customers with specialized competitive solutions, earning RadiSys a strong incumbent
position for future system development projects.

We believe that we have developed a unique and valuable portfolio of technology and
intellectual property associated with our standards-based and other solutions that provides us a competitive advantage. Our objective is to retain the rights to technology developed during the design process. In some cases, we agree to share
technology rights, manufacturing rights, or both, with the customer. However, we generally retain nonexclusive rights to use any shared technology.

Sales, Marketing, and Service

Our products are sold through a variety of channels, including direct sales, distributors and
sales representatives. The total direct sales and marketing headcount was 101 as of January 30, 2009. We use our dedicated cross-functional teams to develop long-term relationships with our customers. Our cross-functional teams include sales,
application engineering, marketing, program management, supply chain management and design engineering. Our teams collaborate with our customers to combine their development efforts in key areas of competency with our standards-based or perfect-fit
solutions to achieve higher quality, lower development and product cost and faster time to market for their products.

We market and sell
our products in North America, the Europe, Middle East and Africa (EMEA) region, and the Asia Pacific region. In each of these geographies, products are sold principally through a direct sales force with our sales resources located in
the U.S., Canada, Europe, Israel, China and Japan. In addition, in each of these geographies we make use of an indirect distribution model and sales representatives to access additional customers. In 2008, global revenues were comprised
geographically of 32.5% from North America, 37.0% from EMEA and 30.5% from Asia Pacific. See Note 20 of the Notes to the Consolidated Financial Statements for financial information by geographic area.

We believe that along with providing our customers competitive time to market, low-cost and high-quality products, our global services
organizations detailed involvement, beginning early in the product life-cycle, reduces our customers product risks. Service areas include warranty, repair, integration, training as well as product upgrades and enhancements in some our
next-generation ATCA products.

Manufacturing Operations

We utilize a combination of internal and outsourced manufacturing. Total manufacturing operations headcount was 309 as of January 30, 2009. We currently manufacture approximately 15% of our own products and
intend to continue to shift manufacturing to third party contract manufacturers located in low cost regions.

##### Table of Contents

We have an automated ISO9001 certified plant in Hillsboro, Oregon that provides board and systems
assembly and testing. This plant includes an automated Surface Mount Technology (SMT) line which allows double-sided board assembly. Because many of our products typically have long life reliability requirements, they must undergo
particularly rigorous stress testing.

We also have an integration facility in Burnaby, British Columbia, which is responsible for the
final integration, testing and delivery of Media Server systems. This organization works closely with our contract manufacturer to oversee the manufacturing process and functionally test all hardware components of an end system.

In addition to the facilities where we manufacture, integrate and test our products, we also utilize our offices in Shenzhen, China and Penang, Malaysia
to oversee the manufacturing conducted by our contract manufacturing partners in these regions. The oversight includes supply chain management as well as quality control.

Although many of the raw materials used in our internal and outsourced manufacturing operations are available from a number of alternative sources, some of these are obtained from a single supplier or a limited number
of suppliers. We and our outsourced manufacturing partners contract with third parties for a continuing supply of the components used in the manufacture of our products. We currently rely solely on Intel for the supply of some microprocessors and
other components. Alternative sources of components that are procured from one supplier or a limited number of suppliers would be difficult to locate and/or it would require a significant amount of time and resources to establish and accommodate.

We increasingly rely on contract manufacturers for certain RadiSys products. Alternative sources of manufacturing services for the RadiSys
products, including transitioning the products, could require significant time and resources to establish. In addition, any decline in the quality of components supplied by our vendors or products produced by our contracting manufacturing partners
could adversely impact our reputation and business performance.

Backlog

As of December 31, 2008, our backlog was approximately $34.4 million, compared to $33.8 million as of December 31, 2007. We include in our
backlog statistic all purchase orders scheduled for delivery within 12 months.

Intellectual Property

We hold 32 U.S. and 28 foreign utility patents, two U.S. design patents and have five U.S. and 13 foreign patent applications pending. We also rely on
trade secrets, know how and rapid time to market for protection and leverage of our intellectual property. We have, from time to time, been made aware of others in the industry who assert exclusive rights to certain technologies, usually in the form
of an offer to license certain rights for fees or royalties. Our policy is to evaluate such claims on a case-by-case basis. We may seek to enter into licensing agreements with companies having or asserting rights to technologies if we conclude that
such licensing arrangements are necessary or desirable in developing specific products.

Employees

As of January 30, 2009, we had 826 employees, of which 669 were regular employees and 157 were agency temporary employees or contractors. We are not
subject to any collective bargaining agreement, have never been subject to a work stoppage, and believe that we have maintained good relationships with our employees.

Corporate History

RadiSys Corporation was incorporated in March 1987 under the laws of the State of
Oregon. Our principal offices are located at 5545 N.E. Dawson Creek Drive, Hillsboro, OR 97124; our telephone number is (503) 615-1100. Our website address is www.radisys.com.

|Item 1A. | Risk Factors
|-------- | ------------

There are many
factors that affect our business and the results of our operations, many of which are beyond our control. The risks described in this Annual Report on Form 10-K for the year ended December 31, 2008, are not the only risks facing our Company.
Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Because of our dependence on certain customers, the loss of, or a substantial decline in sales to, a top customer could have a material adverse effect on our
revenues and profitability.

For 2008 and 2007, we derived 59.7% and 66.0%, respectively, of our revenues from our five largest
customers during these periods. These five customers were Nokia Siemens Networks, Philips Healthcare, Danaher, Agilent and Fujitsu. During 2008, revenues attributable to Nokia Siemens Networks were 43.5%. During 2007, revenues attributable to Nokia
Siemens Networks were 44.8%. Because of our significant customer concentration, our largest customers have additional pricing power over us. Further, a financial hardship experienced by, or a substantial decrease in sales to, any one of our
customers could materially affect our revenues and profitability. Generally, these customers are not the end-users of our products. If any of these customers efforts to market the products we design and manufacture for them or the end products
into which our products are incorporated are unsuccessful in the marketplace or if these customers experience a decrease in demand for such products, our design wins, sales and/or profitability will be significantly reduced. Furthermore, if these
customers experience adverse economic conditions in the end markets into which they sell our products, we would expect a significant reduction in spending by these customers in addition to increasing our exposure to credit risk, which may limit our
ability to collect. Some of these end markets are characterized by intense competition, rapid technological change and economic uncertainty and as such there is no guarantee that the revenues associated with the potential loss of a key customer will
be replaced by the establishment of new business relationships. Our exposure to economic cyclicality and any related fluctuation in demand from these customers could have a material adverse effect on our revenues and financial condition.

Our operating results may be adversely impacted by worldwide political and macro- economic uncertainties and fears.

Recently general worldwide economic conditions have experienced a significant downturn due to the credit conditions impacted by factors such as the
subprime-mortgage turmoil, slower economic activity, concerns about inflation and deflation, increased energy costs, decreased consumer confidence, reduced corporate profits and capital spending, adverse business conditions and liquidity, the
ongoing effects of the war in Iraq, recent international conflicts and terrorist and military activity, and the impact of natural disasters and public health emergencies. These conditions make it extremely difficult for our customers, our vendors
and us to accurately forecast and plan future business activities, and they could cause U.S. and foreign businesses to slow spending on our products and services, which would lengthen sales cycles and, ultimately, reduce our revenues and
profitability. Furthermore, during challenging economic times our customers may face issues gaining timely access to sufficient credit, which could result in an impairment of their ability to make timely payments to us. If that were to occur, we may
be required to increase our allowance for doubtful accounts and our days sales outstanding would be negatively impacted. We cannot predict the timing, depth or duration of any economic slowdown or subsequent economic recovery, worldwide, or in the
markets in which we operate. If the economy



11



---

##### Table of Contents

or markets in which we operate do not continue at their present levels, our business, financial condition and results of operations could be materially and
adversely affected. All the aforementioned macro-economic challenges and conditions could negatively impact our results of operations.

We have
shifted our business from predominately perfect fit (custom) solutions to more standards-based products, such as ATCA, IP Media Servers, and COM Express. This required substantial expenditures for R&D and if this strategy is not successful, our
long-term revenues, profitability and financial condition could be materially and adversely affected

We have shifted our business
from predominately perfect fit solutions, or custom, to more standards-based solutions, such as ATCA, IP Media Server, and COM Express products. We believe that over the next several years customers will continue to increasingly design their
embedded computing platforms around standards-based architectures and increasingly source embedded solutions from third-party suppliers, such as RadiSys. However, there can be no assurance that this strategy will be successful and the current state
of the economy could further delay or prolong the transition or adoption of standards-based products. This strategy required us to make substantial expenditures for R&D in new technologies, which were reflected as current expenses in our
financial statements. There is no assurance that these new products and technologies will be accepted by all of our customers and, if accepted, how large the market will be for these products or what the timing will be for any meaningful revenues.
Customers may not choose to use standards-based products to the extent that we are projecting or in the timeframe that we are projecting, and if customers instead continue to use perfect fit architectures when designing their systems, we may not be
well positioned to receive orders for such projects, or if we do receive such orders, they may not be profitable given our operational focus on standards-based solutions. If we are unable to successfully develop and sell standards-based products to
our customers, our revenues, profitability and financial condition could be materially adversely affected. Additionally, if we successfully develop standards-based products we may incur incremental R&D expenses as we tailor the standards-based
products for our customers. Furthermore, we are building standards-based products to meet industry standards that define the basis of compatibility in the operation and communication of a system supported by different vendors. Those standards
constantly change and new competing standards emerge. The development or adaptation of products and technologies requires us to commit financial resources, personnel and time significantly in advance of sales. In order to compete, our decisions with
respect to those commitments must accurately anticipate, sometimes two years or more in advance, both future demand and the technologies that will gain market acceptance to meet that demand.

Our projections of future revenues and earnings are highly subjective and may not reflect future results which could cause volatility in the price of our common
stock.

We have contracts with most of our major customers but these contracts do not commit them to purchase a minimum amount of
our products. These contracts generally require our customers to provide us with forecasts of their anticipated purchases. However, our experience indicates that customers can change their purchasing patterns quickly in response to market demands,
changes in their management or strategy, among other factors, and therefore these forecasts may not be relied upon to accurately forecast sales. From time to time we provide projections to our shareholders and the investment community of our future
sales and earnings. Since we do not have long-term purchase commitments from our major customers and the customer order cycle is short, it is difficult for us to accurately predict the amount of our sales and related earnings in any given period.
Our projections are based on managements best estimate of sales using historical sales data, information from customers and other information deemed relevant. These projections are highly subjective since sales to our customers can fluctuate
substantially based on the demands of their customers and the relevant markets. Our period to period revenues have varied in the past and may continue to vary in the future. Unanticipated reductions in purchase orders from our customers may also
result in our having to write off excess or obsolete inventory. In addition and as stated above, we have a high degree of customer concentration. Any significant change in purchases by any one of our large customers can significantly affect our
sales and profitability.

##### Table of Contents

If demand for our products fluctuates, our revenues, profitability and financial condition could be
adversely affected. Important factors that could cause demand for our products to fluctuate include:



| |  |  | changes in customer product needs;
| | - |  | ----------------------------------



| |  |  | changes in the level of customers inventory;
| | - |  | ---------------------------------------------



| |  |  | changes in business and economic conditions;
| | - |  | --------------------------------------------



| |  |  | changes in the mix of products we sell; and
| | - |  | -------------------------------------------



| |  |  | market acceptance of our products.
| | - |  | ----------------------------------

The price of our common stock may be adversely affected by numerous factors, such as general economic and market conditions, changes in analysts estimates regarding earnings as well as factors relating to the commercial systems and
communication networking markets in general. We cannot accurately forecast all of the above factors. As a result, we believe that period-to-period comparisons may not be indicative of future operating results. Our operating results in any future
period may fall below the expectations of public market analysts or investors.

Our failure to develop and introduce new products on a timely basis
could harm our ability to attract and retain customers.

Our industry is characterized by rapidly changing technology, frequent
product introductions and ongoing demands for greater speed and functionality. Therefore, we must continually design, develop and introduce new products with improved features to be competitive. To introduce these products on a timely basis we must:



| |  |  | design innovative and performance-improving features that differentiate our products from those of our competitors;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | identify emerging technological trends in our target markets, including new standards for our products;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | accurately define and design new products to meet market needs;
| | - |  | ---------------------------------------------------------------



| |  |  | anticipate changes in end-user preferences with respect to our customers products;
| | - |  | -----------------------------------------------------------------------------------

Not all new design wins ramp into production, and even if ramped into production, the timing of such production may not occur as we or our customers had estimated
or the volumes derived from such projects may not be as significant as we had estimated, which could have a substantial negative impact on our anticipated revenues and profitability.

We have historically estimated the revenue from design wins, which can represent up to three years of revenue once product development has ramped into
production. If a design win actually ramps into production, the average ramp into production begins about 12 to 18 months after the initial design win, although some more complex projects can take up to 24 months or longer. After that,
there is an additional time lag from the start of production ramp to peak revenue. Not all design wins ramp into production and, even if a design win ramps into production, the volumes derived from such projects may be less than we had originally
estimated. Products related to design wins are sometimes canceled or delayed, or can perform below original expectations, which can adversely impact anticipated revenues and profitability. In particular, the volumes and time to production ramp
associated with new design wins depend on the adoption rate of new technologies in our customers end markets, especially in the communications networking sector. Program delays or cancellations could be more frequent during times of meaningful
economic downturn. Should technologies such as Voice over IP, IP Multimedia Subsystem, 3G wireless technologies, IPTV, advanced multimedia applications and other emerging technologies

not be adopted as fast as we or our customers anticipate, actual volumes from new design wins may be lower than we are expecting, which could adversely
affect our revenue and gross margin.

Our business depends on conditions in the communications networking and commercial systems markets. Demand in
these markets can be cyclical and volatile, and any inability to sell products to these markets or forecast customer demand due to unfavorable or volatile market conditions could have a material adverse effect on our revenues and gross margin.

We derive our revenues from a number of diverse end markets, some of which are subject to significant cyclical changes in demand.
In 2008, we derived 78.5% and 21.5% of our revenues from the communications networking and commercial systems markets, respectively. In 2007, we derived 76.0% and 24.0% of our revenues from the communications networking and commercial systems
markets, respectively. We believe that our revenues will continue to be derived primarily from these two markets. Communications networking revenues include, but are not limited to, sales to Alcatel Lucent, Aspect Telecom, Avaya, Bigband Networks,
British Telecom, Cisco Systems, Comverse, Danaher, Fujitsu, Hewlett Packard, Huawei Technologies Co., IBM, IP Access, Italtel, Kineto Wireless, Italtel, NEC, Nokia Siemens Networks, Nortel, West Corporation, and ZTE. Commercial systems revenues
include, but are not limited to, sales to Agilent Technologies, Arrow Electronics, Danaher, Miltope, Mindray, Philips Healthcare, Siemens Medical and Universal Instruments. Generally, our customers are not the end-users of our products. If our
customers experience adverse economic conditions in the end markets into which they sell our products, we would expect a significant reduction in spending by our customers. Some of these end markets are characterized by intense competition, rapid
technological change and economic uncertainty. Our exposure to economic cyclicality and any related fluctuation in customer demand in these end markets could have a material adverse effect on our revenues and financial condition. We are expanding
into applications either through new product development projects with our existing customers or through new customer relationships, but no assurance can be given that this strategy will be successful.

We forecast manufacturing needs based on customer demand. Changes in this demand could cause us or our contract manufacturers to hold excess or obsolete
inventory that may not be salable to other customers on commercially reasonable terms, and which could require inventory valuation write downs that reduce our gross margin and profitability. This risk is exacerbated by a current trend from our
customers of requiring shorter lead times between placing orders with us and the shipment date. That typically necessitates an increase in our inventory or inventory of our products at our contract manufacturers locations, raising the
likelihood that upon cancellation or deferral, we may be holding greater amounts of inventory and/or incurring additional costs. Additionally, we have adverse purchase commitment liabilities, which means we are contractually obligated to reimburse
our contract manufacturers for the cost of excess inventory used in the manufacture of our products for which there is no forecasted or alternative use.

In addition, customer demand for our products is subject to significant fluctuation. A prolonged economic downturn in the business or geographic areas in which we sell our products could reduce demand for our products
and result in a decline in our revenue, gross margin and overall profitability. Volatility and disruption of financial and credit markets could limit our customers ability to obtain adequate financing to maintain operations and invest in
network infrastructure and therefore could also reduce demand for our products and result in a decline revenue, gross margin and overall profitability. If we overestimate demand, we may experience underutilized capacity and excess inventory levels.
As such, if we underestimate demand, we may miss sales opportunities and incur additional costs for labor overtime, equipment overuse and logistical complexities. Unexpected decreases in customer demand or our inability to accurately forecast
customer demand could also result in increases in our adverse purchase commitment liability and have a material adverse effect on our gross margins and profitability.

Because of our dependence and our contract manufacturers dependence on a few suppliers, or in some cases one
supplier, for some of the components we use, as well as our dependence on a few contract manufacturers to supply a majority of our products, a loss of a supplier, a decline in the quality of these components, a shortage of any of these components,
or a loss or degradation in performance of a contract manufacturer could have a material adverse effect on our business or our profitability.

We depend on a few suppliers, or in some cases one supplier, for a continuing supply of the components we use in the manufacture of our products and any disruption in supply could adversely impact our financial
performance. For example, we currently solely rely on Intel for the supply of some microprocessors and other components. Alternative sources of components that are procured from one supplier or a limited number of suppliers would be difficult to
locate and/or would require a significant amount of time and resources to establish. We have in the past experienced and may in the future experience difficulty obtaining adequate quantities of key components used in certain of our products, which
have resulted and may result in delayed or lost sales. In addition, current economic conditions expose us to an increased risk of vendor insolvency, which, given our reliance upon a limited supply base, could result in an inability to procure
adequate quantities of materials and components to meet our customers demand and/or ability to procure the quality of materials and components our customers require.

We also rely on contract manufacturers. In 2008, contract manufacturers provided approximately 85% of all of our unit volume, most of which was
attributable to Foxconn and Jabil. Furthermore, we intend to continue transferring manufacturing capabilities to our contract manufacturers in the future, and there is no guarantee that these transitions will be successful and timely. In addition,
if these third party manufacturers fail to adequately perform, our revenues and profitability could be adversely affected. Among other things, inadequate performance by our contract manufacturers could include the production of products that do not
meet our quality standards or schedule and delivery requirements and could cause us to manufacture products internally or seek additional sources of manufacturing. Additionally, if our contract manufacturers are responsible for a patent or copyright
infringement (including through the supply of counterfeit parts), we may or may not be able to hold them responsible and we may incur costs in defending claims or providing remedies. Such infringements may also cause our customers to abruptly
discontinue selling the impacted products, which would adversely affect our net sales of those products, and could affect our customer relationships more broadly. In addition, alternative internal or external sources of manufacturing for our
products could require significant time and resources to establish or transition.

We operate in intensely competitive industries, and our failure to
respond quickly to technological developments and incorporate new features into our products could have an adverse effect on our ability to compete.

We operate in intensely competitive industries that experience rapid technological developments, changes in industry standards, changes in customer requirements, and frequent new product introductions and
improvements. If we are unable to respond quickly and successfully to these developments, we may lose our competitive position, and our products or technologies may become uncompetitive or obsolete. Similarly, if there are changes to technology
requirements, it can render our products and technologies uncompetitive. To compete successfully, we must maintain a successful R&D effort, develop new products and production processes, and improve our existing products and processes at the
same pace or ahead of our competitors. We may not be able to successfully develop and market these new products; the products we invest in and develop may not be well received by customers; and products developed and new technologies offered by
others may affect the demand for our products. These types of events could have a variety of negative effects on our competitive position and our profitability and financial condition, such as reducing our revenue, increasing our costs, lowering our
gross margin, and requiring us to recognize and record impairments of our assets.

Competition in the market for embedded systems is intense, and if we lose our market share, our revenues and
profitability could decline.

We face competition in the design of embedded solutions from a number of sources. Our principal
competition remains the internal design resources of our own customers. Many of our customers retain the ability to design embedded solutions in-house. In order to achieve design wins and receive subsequent orders, we must convince our customers of
the benefits associated with using our design services and solutions rather than solutions designed by their in-house personnel. While we believe that many of our customers will increase the proportion of their solutions sourced from merchant
suppliers, we will need to continue to demonstrate the benefits of our solutions relative to similar products that could be developed by our customers internal personnel in order to successfully execute our strategy. In addition, consolidation
of our customers can cause material changes in their use of third parties to realize new product designs.

We also compete with a number of
companies and divisions of companies that focus on providing embedded solutions, including, but not limited to, Advantech Co., AudioCodes, a division within Emerson, a division within General Electric Company, Hewlett-Packard, Interphase, IBM,
Kontron AG, Mercury Computer Systems, Movius, and Sun Microsystems.

Because the embedded systems market is growing, the market is
attracting new non-traditional competitors. These non-traditional competitors include contract manufacturers that provide design services and Asian-based original design manufacturers.

Some of our competitors and potential competitors have a number of significant advantages over us, including:



| |  |  | a longer operating history;
| | - |  | ---------------------------



| |  |  | greater name recognition and marketing power;
| | - |  | ---------------------------------------------



| |  |  | preferred vendor status with our existing and potential customers;
| | - |  | ------------------------------------------------------------------



| |  |  | significantly greater financial, technical, marketing and other resources, which allow them to respond more quickly to new or changing opportunities, technologies
and customer requirements;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | broader product and service offering to provide more complete and valued solutions; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | lower cost structures which, among other things, could include different accounting principles relative to U.S. generally accepted accounting principles
(GAAP).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------

Furthermore, existing or potential competitors may establish cooperative relationships with each
other or with third parties or adopt aggressive pricing policies to gain market share.

As a result of increased competition, we could
encounter significant pricing pressures and/or suffer losses in market share. These pricing pressures could result in significantly lower average selling prices for our products. We may not be able to offset the effects of any price reductions with
an increase in the number of customers, cost reductions or otherwise. In addition, many of the industries we serve, such as the communications industry, are encountering market consolidation, or are likely to encounter consolidation in the near
future, which could result in increased pricing pressure and additional competition thus weakening our position or causing delays in new design wins and their associated production.

Acquisitions and partnerships may be more costly or less profitable than anticipated and may adversely affect the price of our common stock.

Future acquisitions and partnerships may involve the use of significant amounts of cash, potentially dilutive issuances of equity or equity-linked
securities, issuances of debt and amortization of intangible assets with determinable lives. We may also be required to record a charge against earnings upon consummation of the



16

##### Table of Contents

acquisition in respect of the value of an acquired business technology that does not meet the accounting definition of completed
technology. Moreover, to the extent that any proposed acquisition or strategic investment is not favorably received by shareholders, analysts and others in the investment community, the price of our common stock could be adversely affected. In
addition, acquisitions or strategic investments involve numerous risks, including:



| |  |  | difficulties in the assimilation of the operations, technologies, products and personnel of the acquired company;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | the diversion of managements attention from other business concerns;
| | - |  | ---------------------------------------------------------------------



| |  |  | the risks of entering markets in which we have no or limited prior experience;
| | - |  | ------------------------------------------------------------------------------



| |  |  | the potential loss of key employees of the acquired company;
| | - |  | ------------------------------------------------------------



| |  |  | unanticipated liabilities;
| | - |  | --------------------------



| |  |  | performance by the acquired business below our expectations; and
| | - |  | ----------------------------------------------------------------



| |  |  | issues with meeting the needs of acquired customers.
| | - |  | ----------------------------------------------------

In the event that we make an acquisition or enter into a partnership and we are unable to successfully integrate operations, technologies, products or personnel that we acquire, our business, results of operations and
financial condition could be materially adversely affected. We may expend additional resources without receiving a related benefit from strategic alliances with third parties.

We have incurred, and may in the future incur, restructuring and other charges, the amounts of which are difficult to predict accurately.

From time to time, we seek to optimize our operational capabilities and efficiencies and focus our efforts and expertise through business restructurings.
In the future we may decide to further restructure our operations, and possible adverse consequences related to such actions may include various charges for such items as idle capacity, disposition costs, severance costs, loss of propriety
information and in-house knowledge. We may be unsuccessful in any of our current or future efforts to restructure our business. Our restructuring activities may have a material adverse effect upon our business, financial condition or results of
operations.

Our international operations expose us to additional political, economic and regulatory risks not faced by businesses that operate only
in the United States.

In 2008 and 2007, as measured by delivery destination, we derived 1.6% and 2.1%, respectively, of our
revenues from Canada and Mexico, 37.0% and 40.6%, respectively, of our revenues from EMEA and 30.5% and 26.8%, respectively, from Asia Pacific. For the year ended December 31, 2008, approximately 78% of our unit volume consisted of products
manufactured by our China contract manufacturer. During 2006, we completed the acquisition of Convedia, which includes significant operations in Burnaby, British Columbia. Also, in September 2007, we acquired assets from Intel that include
operations in Malaysia. In January 2008, we opened an office in Penang, Malaysia, which houses operational staff to support our Malaysian contract manufacturer as well as a small group of support and design engineers. As a result of all these
activities, we are subject to worldwide economic and market conditions risks generally associated with global trade, such as fluctuating exchange rates, tariff and trade policies, domestic and foreign tax policies, foreign governmental regulations,
political unrest, wars and other acts of terrorism and changes in other economic conditions. These risks, among others, could adversely affect our results of operations or financial position. Additionally, some of our sales to overseas customers are
made under export licenses that must be obtained from the U.S. Department of Commerce. Protectionist trade legislation in either the United States or other countries, such as a change in the current tariff structures, export compliance laws, trade
restrictions resulting from war or terrorism, or other trade policies could adversely affect our ability to sell or to manufacture in international markets. Additionally, U.S. federal and state



17

##### Table of Contents

agency restrictions imposed by the Buy American Act or the Trade Agreement Act may apply to our products manufactured outside the United States. Furthermore,
revenues from outside the United States are subject to inherent risks, including the general economic and political conditions in each country. As a result of the recent financial crisis and tightening of the credit markets, our customers and
suppliers may face issues gaining timely access to sufficient credit, which could impair our customers ability to make timely payments to us and could cause key suppliers to delay shipments and face serious risks of insolvency. These risks,
among others, could adversely affect our results of operations or financial position.

Our ability to procure contracts, maintain and increase
revenues in foreign markets may be negatively impacted by increasing protectionism of foreign governments.

Some foreign
governments have come under increased pressure to protect their domestic economy and national security. Economic and security concerns have resulted in increasing protectionism that excludes foreign market participants from successfully procuring
contracts and gaining sales in foreign markets. As a result, our revenues could decrease and business and operating results could be adversely affected.

If we are unable to generate sufficient income in the future, we may not be able to fully utilize our net deferred tax assets or support our current levels of intangible assets on our balance sheet.

We cannot provide assurance that we will generate sufficient taxable income to fully utilize our net deferred tax assets, which were $56.4 million as of
December 31, 2008. We may not generate sufficient taxable income due to earning lower than forecasted net income or incurring charges associated with unusual events, such as restructurings and acquisitions. Accordingly, we may record a full
valuation allowance against the deferred tax assets if our expectations of future taxable income are not achieved. On the other hand, if we generate taxable income in excess of our expectations, the valuation allowance may be reduced accordingly. We
also cannot provide assurance that future income will support the carrying amount of our remaining intangible assets, which were $19.8 million as of December 31, 2008, and therefore, we may incur an impairment charge in the future.

Our products for embedded solutions are based on industry standards, which are continually evolving, and any failure to conform to these standards or lack of
success of these standards could have a substantial negative impact on our revenues and profitability. In addition, these standards could take longer to be deployed or may not be deployed at all.

We develop and supply a mix of perfect fit (custom) and standards-based products. The industry standards upon which standards-based products for embedded
computing are based are continually evolving. Our future success in these products will depend, in part, upon the success of these standards in the market and our capacity to invest in, and successfully develop and introduce new products based on
emerging industry standards. Reduced market acceptance of these standards and our inability to invest in or conform to these standards could render parts of our product portfolio uncompetitive, unmarketable or obsolete. As new standards are
developed for our addressable markets, we may be unable to successfully invest in, design and manufacture new products that address the needs of our customers or achieve substantial market acceptance.

If we are unable to protect our intellectual property, we may lose a valuable competitive advantage or be forced to endure costly litigation.

We are a technology dependent company, and our success depends on developing and protecting our intellectual property. We rely on patents, copyrights,
trademarks and trade secret laws to protect our intellectual property. At the same time, our products are complex and are often not patentable in their entirety. We also license intellectual property from third parties and rely on those parties to
maintain and protect their technology. We cannot be certain that our actions will protect our proprietary rights. Any patents owned by us may be invalidated, circumvented or challenged. Any of our patent applications, whether or not being currently
challenged, may not be issued with the scope of the claims we seek, if at all. If we are unable to adequately protect our technology, or if we are unable to continue to obtain or maintain licenses for protected technology

from third parties, it could have a material adverse effect on our results of operations. In addition, some of our products are now designed, manufactured
and sold outside of the United States. Despite the precautions we take to protect our intellectual property, this international exposure may reduce or limit protection of our intellectual property, which is more prone to design piracy outside of the
United States.

Third parties may also assert infringement claims against us in the future; assertions by third parties may result in
costly litigation and we may not prevail in such litigation or be able to license any valid and infringed patents from third parties on commercially reasonable terms. Litigation, regardless of its outcome, could result in substantial costs and
diversion of our resources. Any infringement claim or other litigation against us or by us could materially adversely affect our financial condition and results of operations.

Changes to the inputs used to value our share based awards, could adversely affect our operating results.

In accordance with SFAS 123R, Share-Based Payment, we are required to recognize the fair value of stock options and other share-based payment compensation to employees as compensation expense in the statement
of income. Option pricing models require the input of highly subjective assumptions, including the expected stock price, stock price volatility, expected life and forfeiture rate of such options. We base our estimates on historical experience as
well as other assumptions management believes to be reasonable under the circumstances at the time of updating our assumptions. Accordingly, actual results may differ significantly from these estimates, which could have a material impact on our
financial position and results of operations. Given the unpredictable nature and current significant volatility of the Black-Scholes variables and other management assumptions such as number of options to be granted, underlying strike
price and associated income tax impact, share based payment costs may differ from estimates as well as increase in future periods.

Total
share-based compensation expense decreased for the year end December 31, 2008, as compared to the year ended December 31, 2007, however our stock price volatility has increased during the fourth quarter of 2008, which along with
unfavorable changes in the other assumptions used to value our share based payment arrangements could result in future increased costs. Any such increase will be driven by significant fluctuations to the inputs used in applying our Black-Scholes
valuation model, which may have a material impact on our operating results.

Decreased effectiveness of share-based payment awards could adversely
affect our ability to attract and retain employees.

We have historically used stock options and other forms of share-based payment
awards as key components of our total rewards employee compensation program in order to retain employees and provide competitive compensation and benefit packages. In accordance with SFAS 123R, we began recording charges to earnings for
stock-based compensation expense in the first quarter of fiscal 2006. As a result, we have and will continue to incur increased compensation costs associated with our stock-based compensation programs making it more expensive for us to grant
share-based payment awards to employees in the future. Like other companies, we have reviewed our equity compensation strategy in light of the current regulatory and competitive environment and have decided to reduce the total number of options
granted to employees and the number of employees who receive share-based payment awards. Due to this change in our stock-based compensation strategy, we may find it difficult to attract, retain and motivate employees, and any such difficulty could
materially adversely affect our business.

As of December 31, 2008, we had 2.1 million outstanding stock options awarded to our
employees with an average grant price of $15.46. In addition, approximately 97% of outstanding options were issued at a price above the closing price of our stock on December 31, 2008. If our stock price continues to decline, our stock option
program will become ineffective as an incentive to retain key employees.

We rely on our key management and depend on the recruitment and retention of qualified personnel, and our failure
to attract and retain such personnel could seriously harm our business.

A small number of key executives manage our business.
Their departure could have a material adverse effect on our operations. In addition, due to the specialized nature of our business, our future performance is highly dependent upon our ability to attract and retain qualified engineering,
manufacturing, marketing, sales and management personnel for our operations. Competition for personnel is intense, and we may not be successful in attracting and retaining qualified personnel. Our failure to compete for these personnel could
seriously harm our business, results of operations and financial condition. In addition, if incentive programs we offer are not considered desirable by current and prospective employees, we could have difficulty retaining or recruiting qualified
personnel. If we are unable to recruit and retain key employees, our product development, and marketing and sales could be harmed.

As of
December 31, 2008, we had 972,000 outstanding stock options awarded to our executive management team with an average grant price of $14.68. As the average grant price of our outstanding options is greater than our current stock price, our stock
option program may become less effective as an incentive to retain our current management team.

Our disclosure controls and internal control over
financial reporting do not guarantee the absence of error or fraud.

Disclosure controls are procedures designed to ensure that
information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms. Disclosure controls are also designed to ensure
that the information is accumulated and communicated to our management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Internal controls over financial reporting (Internal Controls) are procedures which are designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with accounting principles generally accepted in the United States and includes those policies and procedures that: (1) pertain to the maintenance of records that in reasonable detail
accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Our management, including our
CEO and CFO, do not expect that our disclosure controls or Internal Controls will prevent all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control
systems objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in
all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be
faulty, and breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of
controls is based in part upon certain assumptions about the likelihood of future events, and we cannot assure that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become
inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be
detected.

Oregon corporate law, our articles of incorporation and our bylaws contain provisions that could prevent or
discourage a third party from acquiring us even if the change of control would be beneficial to our shareholders.

Our articles of
incorporation and our bylaws contain anti-takeover provisions that could delay or prevent a change of control of our company, even if a change of control would be beneficial to our shareholders. These provisions:



| |  |  | authorize our Board of Directors to issue up to 5,663,952 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions,
including voting rights, of those shares without prior shareholder approval, which could adversely affect the voting power or other rights of the holders of outstanding shares of preferred stock or common stock;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | establish advance notice requirements for nominations for election to our Board of Directors or for proposing matters that can be acted upon by shareholders at
shareholder meetings;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | prohibit cumulative voting in the election of directors, which would otherwise allow less than a majority of shareholders to elect director candidates; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limit the ability of shareholders to take action by written consent, thereby effectively requiring all common shareholder actions to be taken at a meeting of our
common shareholders.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, if our common stock is acquired in specified transactions deemed to constitute
control share acquisitions, provisions of Oregon law condition the voting rights that would otherwise be associated with those common shares upon approval by our shareholders (excluding, among other things, the acquirer in any such
transaction). Provisions of Oregon law also restrict, subject to specified exceptions, the ability of a person owning 15% or more of our common stock to enter into any business combination transaction with us.

The foregoing provisions of Oregon law and our articles of incorporation and bylaws could limit the price that investors might be willing to pay in the
future for shares of our common stock and value of our convertible notes.

Sales of a significant number of shares of our common stock in the public
markets, or the perception of such sales, could depress the market price of our common stock.

Sales of a substantial number of
shares of our common stock or other equity-related securities in the public markets could depress the market price of our common stock, and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the
effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock. As of December 31, 2008, we had $50.0 million aggregate principal amount of our 2013 convertible senior notes
outstanding. The price of our common stock could be affected by possible sales of our common stock by investors who view convertible notes as a more attractive means of equity participation in our company and by hedging or arbitrage trading activity
which we expect to occur involving our common stock.

The capped call transaction may affect the value of our common stock.

The capped call transaction, which we entered into with a hedge counterparty in connection with the issuance of our 2013 convertible senior notes, is
expected to reduce the potential dilution upon conversion of the 2013 convertible senior notes in the event that the market value per share of our common stock, as measured under the terms of the capped call transaction, at the time of exercise is
greater than the strike price of the capped call transaction, which corresponds to the initial conversion price of the notes and is subject to certain adjustments similar to those contained in the 2013 convertible senior notes. If, however, the
market value per share of our common stock exceeds the cap price of the capped call transaction, as measured under the terms of the capped call transaction, the dilution mitigation under the capped call transaction will be limited, which means that
there would be dilution to the extent that the then market value per share of our common stock exceeds the cap price of the capped call transaction.

##### Table of Contents

In connection with hedging the capped call transaction, the hedge counterparty or its affiliates:



| |  |  | expect to purchase our common stock and/or enter into various derivatives and/or enter into various derivatives transactions with respect to our common stock; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | may enter into or unwind various derivatives and/or purchase or sell our common stock in secondary market transactions.
| | - |  | -----------------------------------------------------------------------------------------------------------------------

These activities could have had the effect of increasing or preventing a decline in the price of our common stock concurrently with or following the
pricing of the 2013 convertible senior notes and could have the effect of decreasing the price of our common stock during the period immediately prior to a conversion of the 2013 convertible senior notes.

The hedge counterparty or its affiliates are likely to modify their hedge positions in relation to the capped call transaction from time to time prior to
conversion or maturity of the notes by purchasing and selling our common stock, other of our securities, or other instruments they may wish to use in connection with such hedging.

In addition, we intend to exercise options we hold under the capped call transaction whenever 2013 convertible senior notes are converted. In order to
unwind its hedge positions with respect to those exercised options, the counterparty or affiliates thereof expect to sell our common stock in secondary market transactions or unwind various derivative transactions with respect to our common stock
during the period immediately prior to conversion of the 2013 convertible senior notes. We have also agreed to indemnify the hedge counterparty and affiliates thereof for losses incurred in connection with a potential unwinding of their hedge
positions under certain circumstances.

The effect, if any, of any of these transactions and activities on the market price of our common
stock will depend in part on market conditions and cannot be ascertained at this time, but any of these activities could adversely affect the value of our common stock.

If the economic viability of our investment bank (UBS AG) deteriorates, we may incur permanent impairment charges which could negatively affect the companys financial condition, cash flow and reported
earnings.

We currently hold investments in auction rate securities (ARS), which are highly rated debt instruments with
a long-term nominal maturity. The majority of our ARS represent interests in collateralized debt obligations supported by pools of government-backed student loans with Standard and Poors (S&P) AAA ratings or Moodys Investor
Service (Moodys) Aaa ratings at the time of purchase. These investments had previously been classified as available-for-sale investments. Available-for-sale securities are recorded at fair value, and unrealized holding gains and
losses are recorded, net of tax, as a separate component of accumulated other comprehensive income.

Between December 31, 2007 and
February 7, 2008, we sold at par value $10.0 million in ARS of the total ARS balance of $72.8 million which was held at December 31, 2007. During the first quarter of 2008, due to liquidity issues experienced in the global credit and
capital markets, our remaining portfolio of ARS experienced multiple failed auctions as the amount of securities submitted for sale exceeded the amount of purchase orders. An auction failure, which is not a default in the underlying debt instrument,
occurs when there are more sellers than buyers at a scheduled interest rate auction date and parties desiring to sell their auction rate securities are unable to do so. When an auction fails, the interest rate is adjusted according to the provisions
of the associated security agreement, which may result in an interest rate that is higher than the interest rate the issuer pays in connection with successful auctions. We will not be able to liquidate the investments until a successful auction
occurs, a buyer is found outside the auction process, the securities are called or refinanced by the issuer, or the securities mature. Due to the uncertainty of when we will be able to liquidate the investments, we reclassified the investments to
long-term assets during the first quarter of 2008.

During August of 2008, UBS AG, the parent company of the securities firm with which we hold our ARS,
announced an offer to its clients holding ARS. Under this offer, UBS AG would issue Auction Rate Securities Rights to us. Subsequently, during the fourth quarter of 2008, we accepted the offer from UBS AG, which gave us a non-transferable right to
require the bank to purchase, at par value, $62.7 million in ARS at any time between June 30, 2010 and June 30, 2012. The agreement allows UBS AG, to purchase the ARS before than June 30, 2010, but it is under no obligation to do
so. If the bank has not purchased the investments by June 30, 2010, we plan to exercise our non-transferable right to require the purchase at that time. In addition, under the terms of the offer, we also became eligible for a demand line
of credit of up to 75% of the market value of our ARS until the time of purchase. As of December 31, 2008, we had drawn $39.5 million under the terms of this agreement.

As a result of accepting the settlement right from UBS AG, in accordance with our policy as well as the provisions of SFAS No. 115, we transferred
our ARS from available-for-sale to trading securities during the fourth quarter of 2008, as we plan to sell them on June 30, 2010. At the time of transfer, we recognized, in earnings, an unrealized loss in the amount of $11.5 million, based on
our estimated valuation of our ARS at that time. Concurrently, we recognized, in earnings, an unrealized gain in the amount of $11.1 million, associated with our acceptance of the settlement right from UBS. This gain was due to our election of the
fair value option under SFAS No. 159  The Fair Value Option for Financial Assets and Financial Liabilities upon initial recognition of this right.

The fair value of both the settlement right and the ARS were derived based on estimates of their respective discounted cash flows. We considered various
inputs to estimate future cash flows for our ARS at December 31, 2008, including the time believed to allow the market for such investments to recover, projected estimates of future interest income, as well premiums designed to account for
liquidity and credit risks associated with our ARS holdings. For our non-transferable right, we considered inputs such as the issuers credit quality, expected term, and estimates of future risk free rates. Our valuation of both components of
our ARS are contingent upon the financial viability of our investment bank and accordingly, we have assigned a credit risk component to our valuations based on market data available at the time of valuation. However, if market conditions change and
our investment bank is unable to fulfil its commitment, we could incur a permanent impairment charge for the fair value assigned to our settlement right, which would materially and adversely affect our operating results and overall financial
condition. Additionally, the inputs used in our valuation are based on managements estimates at the time of valuation and require significant judgment. If any of these inputs vary or market conditions change significantly, actual results may
differ and our overall financial condition and operating results may be materially and adversely affected.

Conversion of our convertible senior
notes will dilute the ownership interest of existing shareholders, including holders who have previously converted their convertible senior notes.

Upon conversion of our 2013 convertible senior notes, some or all of the ownership interests of existing shareholders may be diluted. Although the capped call transaction is expected to reduce potential dilution upon
conversion of our 2013 convertible senior notes, the conversion of our 2013 convertible senior notes could still have a dilutive effect on our earnings per share to the extent that the price of our common stock exceeds the cap price of the capped
call. Any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the anticipated conversion of our 2013 convertible senior notes into shares of
our common stock could depress the price of our common stock.

There are a number of trends and factors affecting our markets, including economic
conditions in the United States, Europe and globally, which are beyond our control. These trends and factors may result in increasing upward pressure on the costs of products and an overall reduction in demand.

There are trends and factors affecting our markets and our sources of supply that are beyond our control and may negatively affect our cost of sales.
Such trends and factors include: adverse changes in the cost of raw commodities and increasing freight, energy, and labor costs in developing regions such as China. Our business

strategy has been to provide customers with faster time-to-market and greater value solutions in order to help them compete in an industry that generally
faces downward pricing pressure. In addition, our competitors have in the past lowered, and may again in the future lower, prices in order to increase their market share, which would ultimately reduce the price we may realize from our customers. If
we are unable to realize prices that allow us to continue to compete on this basis of performance, our profit margin, market share, and overall financial condition and operating results may be materially and adversely affected.

Other Risks Related to Our Business

Other
risk factors include, but are not limited to, changes in the mix of products sold, changes in regulatory and tax legislation, changes in effective tax rates, inventory risks due to changes in market demand or our business strategies, potential
litigation and claims arising in the normal course of business, credit risk of customers and other risk factors.

Our common stock is traded on the NASDAQ Global Select Market under the symbol RSYS. The following table sets forth, for the periods
indicated, the highest and lowest sale prices for the common stock, as reported by the NASDAQ Global Select Market.



|               |  |      |       |     |   |

|Fourth Quarter |  | $    | 17.48 |     | $ | 11.71

|First Quarter  |  |      | 17.60 |     |   | 15.04

The closing price as reported on the NASDAQ Global Select Market on March 3, 2009 was $5.10
per share. As of March 3, 2009, there were approximately 279 holders of record of our common stock. We believe that the number of beneficial owners is substantially greater than the number of record holders because a large portion of our
outstanding common stock is held of record in broker street names for the benefit of individual investors.

Dividend Policy

We have never paid any cash dividends on our common stock and do not expect to declare cash dividends on the common stock in the foreseeable future.
Our ability to pay dividends is restricted by our policy as well as the covenants arising from our line of credit agreement with Silicon Valley Bank. As such, we plan to retain all of our earnings to finance future growth.

Stock Price Performance Graph

The following graph
sets forth our total cumulative shareholder return as compared to the return of the S&P 500 Index and the NASDAQ Computer Manufacturers Index for the period of December 31, 2003 through December 31, 2008. The graph reflects the
investment of $100 on December 31, 2003 in our stock, the S&P 500 and in a published industry peer group index.

Total return also
assumes reinvestment of dividends. As noted above, we have never paid dividends on our common stock. Historical stock price performance should not be relied upon as indicative of future stock price performance.

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

Overview

We have shifted more of our investments from
predominantly perfect fit (custom) solutions to standards-based solutions. We believe standards-based solutions provide our customers a number of fundamental benefits. First, by using ready-made platform solutions rather than ground-start
custom-designs, our customers can achieve significantly shorter product intervals and faster time-to-market. Second, we believe our customers can achieve a lower total cost by using solutions that are leveraged across multiple applications rather
than a single-use proprietary solution. By offering ready-made solutions, we believe we have the opportunity to address a wider range of new market opportunities with the potential for faster time to revenue than with ground-start, custom-designs.
We believe this ability to reuse designs makes our business and investment model more scalable. Finally, we believe a more standards-based product model will allow us to provide more integrated higher value solutions to our customers than we have
typically delivered under a custom-design model. These higher value solutions drive higher price points and therefore more total revenue opportunities for our products.

Financial ResultsTotal revenue was $372.6 million, $325.2 million and $292.5 million in 2008, 2007 and 2006, respectively. Backlog was approximately $34.4 million, $33.8 million and $21.7 million at
December 31, 2008, 2007 and 2006, respectively. Backlog includes all purchase orders scheduled for delivery within 12 months. The increase in revenues during 2008 compared to 2007 was due to increases in revenues in the communications
networking market of $45.4 million along with increased revenues of $2.0 million in the commercial systems market. The increase in revenues during 2007 compared to 2006 was due to increases in revenues in the communications networking and commercial
systems markets of $29.5 million and $3.3 million, respectively. Revenues in the communications networking market increased from 2007 to 2008 primarily due to increases in next generation communication revenues from our Intel MCPD acquisition, for
which a full year of revenues were realized, as well as increases in revenues from organic ATCA and media server products. Revenues in the commercial systems market increased slightly during 2008 compared to 2007, primarily due to increases within
the other commercial submarket, which was partially offset by declines in revenues from the test and measurement and medical submarkets.

From a geographic perspective, from 2007 to 2008 non-U.S. revenues by delivery destination increased by $32.1 million. Specifically, revenues from the Asia Pacific region increased by $26.2 million in 2008 and represented 30.5% of total
revenues, up from 26.8% in 2007. Additionally, revenues from the EMEA region increased $5.9 million and represented 37.0% of total revenues, down from 40.6% in 2007. Increased revenues in both the Asia Pacific and EMEA regions were driven by the
addition of Asian Pacific and European customer revenues resulting from our MCPD acquisition. Increased sales to Nokia Siemens Networks further contributed to these increases. For the year ended December 31, 2008 revenues from North America
increased by $15.3 million as compared to the same period in 2007, but remained flat as a percent of total revenues. The increase was due primarily to the addition of revenues from our MCPD acquisition as well as increased media server revenues.

Gross margins as a percentage of revenues were 25.8%, 22.1% and 27.0% for 2008, 2007 and 2006, respectively. The increase in gross margin
as a percentage of revenues for the year ended December 31, 2008 compared to the same period in 2007 was primarily attributable to an increased mix of revenues from higher margin next generation communication products. This increase was further
driven by operational improvements leading to lower excess and obsolete charges as well as increased leverage of fixed costs. In addition, gross margin improved favorably due to the absence of significant charges associated with the transition from
our North Carolina manufacturer, which occurred in 2007.

During the year ended December 31, 2008, we also incurred a $67.3 million
charge associated with the full impairment of our goodwill balances. A decline in our share price, during the fourth quarter of 2008, was considered a triggering event, which prompted us to perform an impairment analysis that ultimately led to the
impairment charge. The charge was the result of our book value exceeding our fair value.

Net loss was $66.0 million, $17.6 million, $13.0 million in 2008, 2007 and 2006, respectively. Net loss
per share was $2.92, $0.80 and $0.62 for 2008, 2007 and 2006, respectively. The net loss increased from 2007 to 2008, due primarily to the goodwill impairment charge totaling $67.3 million.

Cash and cash equivalents amounted to $74.0 million and $50.5 million at December 31, 2008 and December 31, 2007, respectively. The increase in
cash and cash equivalents was primarily due to operating cash flows in the amount of $34.9 million, which were partially offset by cash outflows for financing in the amount of $15.1 million. Financing cash outflows were driven by repurchases of our
convertible debt and offset partially by new borrowings on our revolving line of credit. Our investments totaled $72.8 million at December 31, 2007 and $62.3 million at December 31, 2008, which includes our ARS settlement right. The
decrease is primarily due to sales of ARS in the first quarter of 2008.

In the following discussion of our financial condition and results
of operations, we intend to provide information that will assist in understanding our financial statements, changes in certain key items in those financial statements from year to year, and the primary factors that accounted for those changes, as
well as how certain accounting principles, policies and estimates affect our financial statements.

Critical Accounting Policies and Estimates

Managements discussion and analysis of our financial condition and results of operations are based upon the Consolidated
Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires management to make estimates and judgments that may affect the reported amounts of assets, liabilities, and revenues
and expenses. On an on-going basis, management evaluates its estimates. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly
uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the financial statements.
Management believes the following critical accounting policies reflect the more significant estimates and assumptions used in the preparation of the Consolidated Financial Statements.

Inventory Valuation

We record
the inventory valuation allowance for estimated obsolete or unmarketable inventories as the difference between the cost of inventories and the estimated net realizable value based upon assumptions about future demand and market conditions. Pursuant
to ARB 43 and SAB Topic 5-BB, our inventory valuation allowances establish a new cost basis for inventory. Factors influencing the provision include: changes in demand; rapid technological changes; product life cycle and development plans; component
cost trends; product pricing; regulatory requirements affecting components; and physical deterioration. If actual market conditions are less favorable than those projected by management, additional provisions for inventory reserves may be required.
Our estimate for the allowance is based on the assumption that our customers comply with their current contractual obligations. We provide long-life support to our customers and therefore we have material levels of customer specific inventory. If
our customers experience a financial hardship or if we experience unplanned cancellations of customer contracts, the current provision for the inventory reserves may be inadequate. Additionally, we may incur additional expenses associated with any
non-cancelable purchase obligations to our suppliers if they provide customer-specific components.

##### Table of Contents

Adverse Purchase Commitments

We are contractually obligated to reimburse our contract manufacturers for the cost of excess inventory used in the manufacture of our products, for which
there is no alternative use. Excess inventory is defined as raw materials or assemblies (components) used in the manufacture of our products for which the contract manufacturers on-hand and on-order quantities are in excess of the
requirements derived from our current product forecast of customer demand. We are liable for excess inventory only to the extent that the contract manufacturer procures components to fulfill the manufacturing requirements as set forth in our current
product forecast and agreed upon lead times and minimum order quantities. Unexpected decreases in customer demand or our inability to accurately forecast customer demand could result in increases in our adverse purchase commitment liability and have
a material adverse effect on our profitability. Factors influencing the adverse purchase commitments liability include: changes in demand, rapid technological changes, product life cycle and development plans, component cost trends, product pricing,
customer liability and physical deterioration. If actual market conditions are less favorable than those projected by management, we may incur additional expenses due to increases in our adverse purchase commitment liabilities. Our estimate for the
adverse purchase commitments liabilities is based on the assumption that our customers comply with their current contractual obligations to us. If our customers experience a financial hardship or if we experience unplanned cancellations of customer
contracts, the current adverse purchase commitments liabilities may be inadequate.

Estimates for adverse purchase commitments are derived
from reports received on a quarterly basis from our contract manufacturers. Increases to this liability are charged to cost of goods sold. When and if we take possession of inventory reserved for in this liability, the liability is transferred from
other liabilities to our excess and obsolete inventory valuation allowance. This liability, referred to as adverse purchase commitments, is provided for in other accrued liabilities in the accompanying balance sheets. Adverse purchase commitments
amounted to $2.0 million and $1.9 million at December 31, 2008 and 2007, respectively.

Accrued Warranty

We provide for the estimated cost of product warranties at the time revenue is recognized. Our standard product warranty terms generally include
post-sales support and repairs or replacement of a product at no additional charge for a specified period of time, which is generally 24 months after shipment. The workmanship of our products produced by contract manufacturers is covered under
warranties provided by the contract manufacturer for a specified period of time ranging from 12 to 15 months. We engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component
suppliers. Our estimated warranty obligation is based upon ongoing product failure rates, internal repair costs, contract manufacturing repair charges for repairs not covered by the contract manufacturers warranty, average cost per call and
current period product shipments. If actual product failure rates, repair rates, service delivery costs, or post-sales support costs differ from our estimates, revisions to the estimated warranty liability would be required. Additionally, we accrue
warranty costs for specific customer product repairs that are in excess of our warranty obligation calculation described above. Accrued warranty reserves are included in other accrued liabilities in the accompanying balance sheets.

Long-Lived Assets

Our
long-lived assets include definite-lived intangible assets and property and equipment. The net balance of our definite-lived intangible assets and property and equipment at December 31, 2008 amounted to $19.8 million and $11.6 million,
respectively.

In previous years our long-lived asset balance has included goodwill, which represents the excess of cost over the assigned
value of the net assets in connection with prior acquisitions. Pursuant to SFAS No. 142, we are required to test goodwill for impairment at least annually. Additionally, we assess goodwill for impairment if any adverse conditions exist that
would indicate impairment. Conditions that would trigger an impairment assessment, include, but are not limited to, (i) a significant decline in the Companys market capitalization, (ii) a



30



---

##### Table of Contents

significant adverse change in legal factors or in the business climate that could affect the value of an asset, (iii) or an adverse action or assessment
by a regulator. The Company is considered one reporting unit. As a result, goodwill impairment testing is performed at the reporting unit level in a two-step process, which consists of, first, comparing the Companys fair value to its carrying
value, including goodwill. If the Companys fair value exceeds its carrying value, applicable goodwill is not considered to be impaired. If the Companys carrying value exceeds its fair value, there is an indication of impairment, in which
case we would perform the second step, including a further and more detailed analysis in order to corroborate any such impairment.

In
accordance with SFAS No. 142, our annual goodwill impairment test was performed during the third quarter of 2008. General economic conditions combined with the resulting decline in the Companys stock price, were considered triggering
events that required us to re-perform our goodwill impairment test at the end of the fourth quarter of 2008. To perform the test, a fair value for the Company was estimated primarily based on the market approach, using the market capitalization
method. An impairment loss was then calculated based on an allocation of the fair value of the Company to the fair value of the Companys assets and liabilities in a manner similar to a purchase price allocation in a business combination. This
resulted in an impairment charge representing the entire balance of goodwill, which totaled $67.3 million, net of adjustments and as of December 31, 2008 we had no remaining indefinite lived intangible assets.

Intangible assets, net of accumulated amortization, primarily consist of acquired patents, completed technology, technology licenses, trade names and
customer lists. Intangible assets are being amortized on a straight-line basis over estimated useful lives ranging from one to ten years. Property and equipment, net of accumulated depreciation, primarily consists of office equipment and software,
manufacturing equipment, leasehold improvements and other physical assets owned by RadiSys. Property and equipment are being depreciated or amortized on a straight-line basis over estimated useful lives ranging from one to 15 years. We assess
impairment of intangible assets and property and equipment whenever conditions indicate that the carrying values of the assets may not be recoverable.

Conditions that would trigger a long-lived asset impairment assessment include, but are not limited to, a significant adverse change in legal factors or in the business climate that could affect the value of an asset
or an adverse action or assessment by a regulator. If we determine that a long-lived asset impairment assessment is required, we must determine the fair value of the asset, which is determined based on the associated value of estimated future cash
flows. We would estimate future cash flows using assumptions about our expected future operating performance. Our estimates of future cash flows may differ from actual cash flow due to, among other things, technological changes, economic conditions
or changes to our business operations. Impairments would be recognized in operating results to the extent that the carrying value exceeds this calculated fair value of the long-lived assets.

Considerable management judgment is required in determining if and when a condition would trigger an impairment assessment of our long-lived assets and
once such a determination has been made, considerable management judgment is required to determine the fair market value of the long-lived asset. If the trading price or the average trading price of our common stock is below the book value per share
for a sustained period or if and when a condition has triggered an impairment analysis of our long-lived assets, we may incur substantial impairment losses due to the write-down or the write-off of our long-lived assets.

The triggering events that resulted in the impairment analysis of goodwill were also considered triggering events that required us to perform an
impairment test of our long lived assets at the end of the fourth quarter of 2008. For our long lived assets, we determined no impairment existed. However, during the analysis we noted that the benefit associated with certain of our intangible
assets exceeded their remaining depreciable lives and therefore we adjusted their remaining depreciable lives prospectively. See Note 9 of the Notes to the Consolidated Financial Statements for additional details regarding these changes in
accounting estimate.

Income Taxes

We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the
carrying amounts and tax bases of the assets and liabilities. We record a valuation allowance to reduce deferred tax assets to the amount expected to more likely than not be realized in our future tax returns. Should we determine that we
would not be able to realize all or part of our net deferred tax assets in the future, adjustments to the valuation allowance for deferred tax assets may be required. The net deferred tax assets amounted to $56.4 million as of December 31,
2008. As of December 31, 2008 we estimate utilization of the net deferred tax assets will require that we generate approximately $56.0 million and $41.5 million in taxable income in the United States and Canada, respectively, prior to the
expiration of net operating loss and tax credit carryforwards which will occur between 2009 and 2028. We have considered future market growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate
and prudent and feasible tax planning strategies in determining the need for a valuation allowance. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, we would increase
the valuation allowance and make a corresponding charge to earnings in the period in which we make such determination. Likewise, if we later determine that we are more likely than not to realize the net deferred tax assets, we would reverse the
applicable portion of the previously provided valuation allowance. All future reversals of the valuation allowance would result in a benefit in the period recognized.

Allowance for Doubtful Accounts

We have a relatively small set of multinational customers
that typically make up the majority of our accounts receivable balance. Our allowance for doubtful accounts is determined using a combination of factors to ensure that our trade receivables balances are not overstated. We record reserves for
individual accounts when we become aware of a customers inability to meet its financial obligations to us, such as in the case of bankruptcy filings or deterioration in the customers operating results or financial position. If
circumstances related to customers change, our estimates of the recoverability of receivables would be further adjusted. At December 31, 2008, 39.8% of our accounts receivable was due from our two largest customers. If one of these large
customers or a number of our smaller customers files for bankruptcy or otherwise is unable to pay the amounts due to us, the current allowance for doubtful accounts may not be adequate. During the years ended December 31, 2008 and 2007, there
were no significant account balances reserved for and the allowance for doubtful accounts increased by $86,000 as a result of additional provisions partially offset by the write-off of previously specifically-identified account balances.

We maintain a non-specific bad debt reserve for all customers based on a variety of factors, including the length of time receivables are past due,
trends in overall weighted average risk rating of the total portfolio, macroeconomic conditions, significant one-time events and historical experience. Typically, this non-specific bad debt reserve amounts to approximately 1% of quarterly revenues.

Accrued Restructuring and Other Charges

Expenses associated with exit or disposal activities are recognized when probable and estimable. Because we have a history of paying severance benefits, the cost of severance benefits associated with a restructuring
charge is recorded when such costs are probable and the amount can be reasonably estimated.

For leased facilities that were vacated and
subleased, an amount equal to the total future lease obligations from the date of vacating the premises through the expiration of the lease, net of any future sublease income, was recorded as a part of restructuring charges.

We have engaged, and may continue to engage, in restructuring actions, which require us to make significant estimates in several areas including:
realizable values of assets made redundant or obsolete; expenses for severance and other employee separation costs; the ability to generate sublease income, as well as our ability

##### Table of Contents

to terminate lease obligations at the amounts we have estimated; and other exit costs. Should the actual amounts differ from our estimates, the amount of the
restructuring charges could be materially impacted. For a description of our restructuring actions, refer to our discussion of restructuring charges in the Results of Operations section.

Revenue Recognition

We
recognize revenue when the earnings process is complete, as evidenced by the following revenue recognition criteria: an agreement with the customer; fixed pricing; transfer of title and risk of loss and customer acceptance, if applicable; and that
the collectibility of the resulting receivable is reasonably assured. When a sales arrangement contains multiple elements, such as hardware and software products, licenses and/or services, we allocate revenue to each element based on its relative
fair value, or for software, based on vendor specific objective evidence (VSOE) of fair value. In the absence of fair value for a delivered element, we first allocate revenue to the fair value of the undelivered elements and the residual
revenue to the delivered elements. Where the fair value for an undelivered element cannot be determined, we defer revenue for the delivered elements until the undelivered elements are delivered. We limit the amount of revenue recognition for
delivered elements to the amount that is not contingent on the future delivery of products or services or subject to customer-specified return or refund privileges. We enter into contracts to sell our products and services, and, while the majority
of our sales agreements contain standard terms and conditions under which we recognize revenue upon shipment of product, infrequently we enter into agreements that contain non-standard terms and conditions. Non-standard terms and conditions can
include, but are not limited to, customer acceptance criteria or other post-delivery obligations. As a result, significant contract interpretation is sometimes required to determine the appropriate timing of revenue recognition. The components of
total revenues were as follows (in thousands):

Hardware

Revenue from hardware products where software is incidental is recognized in accordance with Staff Accounting Bulletin (SAB) 104. Under our standard terms and conditions of sale, we transfer title and risk
of loss to the customer at the time product is shipped to the customer and revenue is recognized accordingly, unless customer acceptance is uncertain or significant obligations remain. We reduce revenue for estimated customer returns for rotation
rights as well as for price protection rights according to agreements with our distributors. The amount of revenues derived from these distributors as a percentage of total revenues was 15.2%, 9.9% and 3.4% for the years ended December 31,
2008, 2007 and 2006, respectively.

The software content included in hardware products such as our ATCA systems, certain MCPD products and
CMS solutions are considered to be more than incidental and our ATCA arrangements generally include multiple elements such as hardware, technical support services as well as specified software upgrades or enhancements. As such, the revenue
associated with these products is recognized in accordance with Statement of Positions (SOP) 97-2 Software Revenue Recognition (SOP 97-2).

Software royalties and licenses

Revenue from Software royalties and licenses is recognized in
accordance with SOP 97-2. Revenue from customers for prepaid, non-refundable software royalties is recorded when the revenue recognition criteria have been met. Revenue for non-prepaid royalties is recognized at the time the underlying product is
shipped by the

##### Table of Contents

customer paying the royalty. We recognize software license revenue at the time of shipment or upon delivery of the software provided all relevant revenue
recognition criteria have been met and vendor-specific objective evidence exists to allocate the total fee to all delivered and undelivered elements of the arrangement. We defer revenue on arrangements including specified software upgrades until the
specified upgrade has been delivered.

Software maintenance

Software maintenance services are recognized as earned on the straight-line basis over the terms of the contract in accordance with SOP 97-2. The fair
value of our post-contract support has been determined by renewal rates within the Companys support agreements as well as the actual amounts charged to customers for renewal of their support services.

Engineering and other services

Engineering services revenue is recognized upon completion of certain contractual milestones and customer acceptance of the services rendered in accordance with SOP 81-1 Accounting for Performance of Construction-Type and Certain
Production-Type Contracts (SOP 81-1). Other services revenues include hardware repair services and custom software implementation projects. Hardware repair services revenues are recognized when the services are complete. Software
implementation revenues are recognized upon completion of certain contractual milestones and customer acceptance of the services rendered.

Deferred income

Deferred income represents amounts received or billed for the following types of transactions:



| |  |  | Distributor salesCertain sales are made to distributors under agreements providing price protection and right of return on unsold merchandise. Revenue
and costs relating to such distributor sales are deferred until the product is sold by the distributor or return privileges and price protection rights terminate, at which time related estimated distributor resale revenue, estimated effects of
distributor price adjustments, and estimated costs are reflected in the Consolidated Statement of Operations.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

During the
first quarter of 2008, we entered into new arrangements with our significant distributors servicing the MCPD business. For a few of these distributors, we eliminated some of the price adjustment programs. For those distributors where significant
price adjustment programs remain in place, we will continue to defer revenue until the distributors sell the merchandise.

Our revenue
reporting for these distributors 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, deferred income on sales to distributors, and net income.



| |  |  | Undelivered elements of an arrangementCertain software sales include specified free upgrades and enhancements to an existing product. Revenue for such
products is deferred until the future obligation is fulfilled.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Service salesCertain sales are made for products and related service where the fair value of the service cannot be determined. Revenues for such sales
are deferred until service obligations represent the only undelivered element, at which point revenues are recognized ratably over the requisite service period. The Company limits the amount of revenue recognition for delivered elements to the
amount that is not contingent on the future delivery of products or services or subject to customer-specified return or refund privileges.

Stock-based Compensation

Equity instruments are granted to employees, directors and consultants in certain instances, as defined in the respective plan agreements. In 2008, 2007,
and 2006, we issued stock options, restricted stock, and stock to our employees under our employee stock purchase plan (ESPP).

Effective January 1, 2006, we adopted the fair value recognition provisions of SFAS 123R, using the modified prospective transition method, and therefore have not restated prior periods results. Under this method we recognize
compensation expense for all stock-based employee benefit plan equity awards granted after January 1, 2006 and prior to but not yet vested as of January 1, 2006, in accordance with SFAS 123R. Under the fair value recognition provisions of
SFAS 123R, we recognize stock-based compensation on a straight-line basis over the requisite service period of the award for those shares expected to vest as described below. Prior to SFAS 123R adoption, we accounted for share-based payments under
Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25).

We continue to
use the Black-Scholes model to measure the grant date fair value of stock options and ESPP shares. The grant date fair value of stock options that are expected to vest is recognized on a straight-line basis over the requisite service period, which
is equal to the option vesting period, which is generally three years. The grant date fair value of ESPP shares that are expected to vest is recognized on a straight-line basis over the requisite service period, which is generally 18 months, subject
to modification at the date of purchase due to the ESPP look-back feature. The grant date fair value of restricted stock is equal to the closing price of RadiSys shares as quoted on the NASDAQ Global Select Market on the date of grant. The grant
date fair value of restricted stock that are expected to vest is recognized on a straight-line basis over the requisite service period, which is 3 years. The estimate of the number of options, ESPP shares and restricted stock expected to vest is
determined based on historical experience.

To determine the fair value of the stock options and ESPP shares, using the Black-Scholes
option pricing model, the calculation takes into consideration the effect of the following:



| |  |  | exercise price of the option or purchase price of the ESPP share;
| | - |  | -----------------------------------------------------------------



| |  |  | price of our common stock on the date of grant;
| | - |  | -----------------------------------------------



| |  |  | expected term of the option or share;
| | - |  | -------------------------------------



| |  |  | expected volatility of our common stock over the expected term of the option or share; and
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | risk free interest rate during the expected term of the option or share.
| | - |  | ------------------------------------------------------------------------

The calculation includes several assumptions that require managements judgment. The expected term of the option or share is determined based on
assumptions about patterns of employee exercises and represents a probability-weighted average time-period from grant until exercise of stock options, subject to information available at time of grant. Determining expected volatility generally
begins with calculating historical volatility for a similar long-term period and then considers the ways in which the future is reasonably expected to differ from the past.

As part of our SFAS 123R adoption, we also examined our historical pattern of option exercises in an effort to determine if there were any discernable
activity patterns based on certain employee populations. From this analysis, we identified three employee populations. The expected term computation is based on historical vested option exercises and post-vest forfeiture patterns and includes an
estimate of the expected term for options that were fully vested and outstanding at December 31, 2006 for each of the three populations identified. The estimate of the expected term for options that were fully vested and outstanding at
December 31, 2006 was determined as the midpoint of a range of estimated expected terms determined as follows: the low end of the range assumes the fully vested and outstanding options settle on December 31, 2006 and the high end of the
range assumes that these options expire upon contractual term. The risk free interest rate is based on the U.S. Treasury constant maturities in effect at the time of grant for the expected term of the option or share.

Determining the appropriate fair value model and, as noted above, calculating the fair value of equity
instruments associated with our employee benefit plans require the input of highly subjective assumptions. The assumptions used in calculating the fair value of these equity instruments represent managements best estimates, but these estimates
involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future. In addition, we are
required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. If our actual forfeiture rate is materially different from our estimate the stock-based compensation expense could be significantly
different from what we have recorded in the current period. See Note 19 to the Consolidated Financial Statements for a further discussion on stock-based compensation.

Derivatives

During 2008, we began to enter into forward foreign currency exchange contracts
to reduce the impact of foreign currency exchange risks where natural hedging strategies could not be effectively employed.

We do not hold
or issue derivative financial instruments for trading purposes. The purpose of our hedging activities are to reduce the risk that the eventual cash flows of the underlying assets, liabilities and firm commitments will be adversely affected by
changes in exchange rates. In general, our hedging activities do not create foreign currency exchange rate risk because fluctuations in the value of the instruments used for hedging purposes are offset by fluctuations in the value of the underlying
exposures being hedged. Counterparties to derivative financial instruments expose us to credit-related losses in the event of nonperformance. We do not believe there is a significant credit risk associated with our hedging activities because the
counterparties are all large financial institutions with high credit ratings.

All derivatives, including foreign currency exchange
contracts are recognized on the balance sheet at fair value. When specific criteria required by SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities (SFAS 133) have been met, changes in the fair
values of hedge contracts related to anticipated transactions are recorded in other comprehensive income (loss) rather than net income (loss) until the underlying hedged transaction affects net income. One of the criteria for this accounting
treatment is that the forward foreign currency exchange contract amount should not be in excess of specifically identified anticipated transactions. By their nature, estimates of anticipated transactions may fluctuate over time and may ultimately
vary from actual transactions. If anticipated transaction estimates or actual transaction amounts decrease below hedged levels, or when the timing of transactions change significantly, we would reclassify a portion of the cumulative changes in fair
values of the related hedge contracts from other comprehensive income (loss) to other income (expense) during the quarter in which the changes occur.

We adopted SFAS No. 157, Fair Value Measurements, (SFAS 157); however the adoption did not have a material impact on our results of operations.

Comparison of Year 2008 and Year 2007

Revenues. Revenues increased by $47.4 million, or 14.6%, from $325.2 million in 2007 to $372.6 million in 2008. The increase in revenues during the
year ended December 31, 2008 compared to the year ended December 31, 2007 was driven by increases in revenues in the communications networking and commercial systems markets of $45.4 million and $2.0 million, respectively.

Revenues in the communications networking market increased in 2008 compared to 2007 primarily due to increases in next generation communication revenues
from our Intel MCPD acquisition, for which a full year of revenue was realized, as well increases in revenues from organic ATCA and media server products. Offsetting these increases, were decreased revenues from legacy enterprise products in the IP
networking and messaging markets, as various legacy enterprise products approach end of life.

Revenues in the commercial systems market
increased slightly during 2008 as compared to 2007, primarily due to increases within the other commercial submarket, which offset decreased revenues in the industrial automation, medical, and test and measurement submarkets.

Given the dynamics of these markets, we may experience general fluctuations in the percentage of revenue attributable to each market. As a result, the
quarter to quarter and year to year comparisons of our markets often are not indicative of overall economic trends affecting the long-term performance of our markets. We currently expect that each of our markets will continue to represent a
significant portion of total revenues.

From a geographic perspective, for the year ended December 31, 2008 compared to the same
period in 2007, the percentage of non-US revenues by delivery destination remained relatively flat. Revenues as measured

##### Table of Contents

by destination in the Asia Pacific region increased by $26.2 and represented 30.5% of total revenues up from 26.8% in 2007. Revenues in the EMEA region
increased by $5.9 million in 2008, however, as a percent of total revenues decreased to 37.0% in 2008, down from 40.6% in 2007. Increased revenues from both the Asia Pacific and EMEA regions were driven by the addition of Asian Pacific and European
customer revenues resulting from our MCPD acquisition. Increased sales to Nokia Siemens Networks further contributed to these increases. For the year ended December 31, 2008 revenues from North America increased by $15.3 million compared to the
same period in 2007. This increase is primarily due to the addition of revenues from our MCPD acquisition as well as increased revenues from the media server revenues.

We currently expect continued fluctuations in the percentage of revenue from each geographic region. Additionally, we expect non-U.S. revenues to remain a significant portion of our revenues.

Gross margins as a percentage of revenues were 25.8% and 22.1% for 2008 and 2007, respectively. The increase in gross margin as a percentage of revenues
for the year ended December 31, 2008 compared to the same period in 2007 was primarily attributable to an increased mix of revenues from higher margin next generation communication products. This increase was further driven by operational
improvements ultimately leading to lower excess and obsolete charges as well as increased leverage of fixed costs.

Research and
Development. R&D expenses consist primarily of salary, bonuses and benefits for product development staff, and cost of design and development supplies and equipment, net of reimbursements for non-recurring engineering services. R&D
expenses increased $3.1 million, or 6.7%, from $46.2 million in 2007 to $49.3 million in 2008. The increase for the year ended December 31, 2008 compared to the same period in 2007 was primarily driven by the addition of the MCPD business,
which includes increased headcount as well as stock-based compensation expense. The increase was further driven by increased incentive compensation costs. These increases were partially offset by decreased salary and related costs resulting from the
restructuring activities undertaken in the second quarter of 2008, as well as conscious efforts to manage R&D spending.

Selling,
General, and Administrative. Selling, general and administrative (SG&A) expenses consist primarily of salary, commissions, bonuses and benefits for sales, marketing, executive, and administrative personnel, as well as
professional services and costs of other general corporate activities. SG&A expenses increased $3.0 million, or 6.2%, from $47.9 million in 2007 to $50.8 million in 2008. The increase for the year ended December 31, 2008 compared to the
same period in 2007 is primarily due to increased incentive compensation and sales commission costs, including direct representative costs. These increases in costs are primarily the result of increased revenue, new design wins and improved
operating results. The increase in SG&A year over year was also attributable to the employee and related costs of the MCPD acquisition.

Stock-based Compensation Expense. Stock-based compensation expense for the year ended December 31, 2008 consists of amortization of stock-based compensation associated with stock options, restricted stock and ESPP shares
unvested and outstanding on January 1, 2006 and new stock options, restricted stock and ESPP shares granted for the year ended December 31, 2008. During the year ended December 31, 2008, the Company incurred $9.6 million in
stock-based compensation. During the year ended December 31, 2007, we incurred $9.9 million in stock-based compensation expense.

We

Deferred Compensation Expense. On September 1, 2006, all outstanding Convedia stock options
vested and were considered exercised immediately. The proceeds of which were distributed as follows: 75% of the purchase price per share less the exercise price was paid to the option holder at closing and the remaining 25% will be paid in full to
those Convedia employees still employed by RadiSys after one year of service. The 75% paid at the time of the acquisition is included in the purchase price and is allocated to goodwill. The remaining 25% is recorded as deferred compensation and
amortized through the Consolidated Statement of Operations for the life of the asset (one year). Pursuant to the purchase agreement any forfeitures are reallocated to the remaining Convedia employees. We paid the remaining 25% of the proceeds
calculation on September 30, 2007.

We recognized deferred compensation expense as follows (in thousands):

Intangible Assets Amortization. Intangible assets consist of purchased technology, patents
and other identifiable intangible assets. We reclassified certain amortization in 2007 to cost of sales based on our view that the intangibles are associated with product costs and our revenue-generating process. Amortization of purchased technology
for prior periods is considered immaterial and has not been adjusted. Intangible assets amortization expense included in results of operations was $4.6 million and $4.4 million in 2008 and 2007, respectively. Intangible assets amortization increased
primarily due to the amortization of purchased technology, for which the impact of a full year was realized. We perform reviews for impairment of the purchased intangible assets whenever events or changes in circumstances indicate that the carrying
amount of an asset may not be recoverable.

Restructuring and Other Charges. We evaluate the adequacy of the accrued restructuring
and other charges on a quarterly basis. As a result, we record certain reclassifications and reversals to the accrued restructuring and other charges based on the results of the evaluation. The total accrued restructuring and other charges for each
restructuring event are not affected by reclassifications. Reversals are recorded in the period in which we determine that expected restructuring and other obligations are less than the amounts accrued. Tables summarizing the activity in the accrued
liability for each restructuring event are contained in Note 11 of the Notes to the Consolidated Financial Statements. During 2008 and 2007, we recorded restructuring and other charges and reversals as described below.

First Quarter 2007 Restructuring.During the first quarter of 2007, we incurred employee-related expenses associated with certain engineering
realignments. The costs incurred in this restructuring event are associated with employee termination benefits, including severance and medical benefits. All restructuring activities were completed by September 30, 2007. In 2007, we incurred
$158,000 of employee-related, net expenses. No such charges were incurred during 2008.

Second Quarter 2007 Restructuring.During the second quarter of 2007, we incurred employee-related expenses associated with skill set changes for approximately 20 employees. The changes involved creating an integrated structure with our media server business along with some skill
set changes in certain selling, general and administrative and engineering groups. The costs incurred in this restructuring event include employee severance and medical benefits. In 2007, we incurred $1.3 million of employee-related, net expenses.
No additional charges related to this restructuring event were incurred in the year ended December 31, 2008. All restructuring activities were completed by March 31, 2008.

Second Quarter 2008 Restructuring. During the second quarter of 2008, we initiated a restructuring plan that included the elimination of 23
positions primarily initiated with the intent to return our engineering spend to

levels which align with targeted profitability as well as refocus our skill sets in order to promote new product growth and provide enhanced service and
support to existing customers. During 2008, we incurred $598,000 of employee-related expenses as part of this restructure. We expect to complete all activities associated with the restructuring by March 31, 2009.

Interest Expense. Interest expense includes interest incurred on our convertible notes and the Companys new lines of credit. Interest
expense increased $1.0 million, or 61.0%, from $1.7 million in 2007 to $2.7 million in 2008. The increase in interest expense in 2008 compared to 2007 was due to the issuance of $55.0 million of our 2013 convertible senior notes with an interest
rate of 2.75% on February 6, 2008, along with interest charges incurred from borrowings on our revolving line of credit.

Interest
Income. Interest income decreased $3.3 million, or 52.2%, from $6.4 million in 2007 to $3.1 million in 2008. Interest income decreased as a result of a lower average balance of cash, cash equivalents and investments during 2008 compared to 2007
as well as a decline in the average yield on investment holdings. The decline in cash, cash equivalents and investments was due to the repurchase of $98.4 million and $3.1 million of our 2023 and 2013 convertible notes, respectively. There was also
a decline in cash, cash equivalents and investments resulting from the acquisition of Intels MCPD business in 2007 for approximately $32.0 million.

Other Income (Expense), Net.Other income (expense), net, primarily includes foreign currency exchange gains and losses. Other income (expense), net, was $629,000 in 2008 compared to $(169,000) in 2007. The
increase is primarily due to net gains on the buyback of our convertible notes, which totaled $843,000 during 2008.

Income Tax
Provision. We recorded tax benefits of $9.5 million and $6.0 million for the years ended December 31, 2008 and 2007, respectively. Our effective tax rate for the year ended 2008 was (12.6%) compared to (25.5%) for the year ended
December 31, 2007. The Companys current effective tax rate differs from the statutory rate primarily due to the impact of goodwill impairment, stock option expense, research and development tax credits generated in 2008, the revaluation
of certain net deferred tax assets due to changes in foreign currency exchange rates and taxes on foreign income that differ from U.S. tax rate.

On October 3, 2008, the Emergency Economic Stabilization Act of 2008 was signed into law which extended the research and development tax credit through December 31, 2009. Congress has reinstated the tax credit retroactive to
January 1, 2008. We have recorded federal and Canadian research and development credits of approximately $709,000 and $1.3 million, respectively, for the year ended 2008.

At December 31, 2008, we had net deferred tax assets of $56.4 million. Valuation allowances of $5.6 million and $6.3 million, as of
December 31, 2008 and 2007, respectively, have been provided for deferred income tax assets related primarily to net operating loss and tax credit carryforwards that may not be realized. The decrease in valuation allowance of $752,000 for the
year ended December 31, 2008 compared to the year ended December 31, 2007 is primarily attributable to an increase in the utilization of net operating loss carryforwards from the acquisition of Microware in August 2001 and the expiration
of a capital loss carryforward that was previously reserved. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, we would increase the valuation allowance and make a
corresponding charge to earnings in the period in which we make such determination. Likewise, if we later determine that we are more likely than not to realize the net deferred tax assets, we would reverse the applicable portion of the previously
provided valuation allowance. All future reversals of the valuation allowance would result in a benefit in the period recognized. Although realization is not assured, management believes that it is more likely than not that the balance of the
deferred tax assets, net of the valuation allowance, as of December 31, 2008 will be realized.

The Company recognizes uncertain tax
positions in accordance with FASB Interpretation No. 48 Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement 109 (FIN 48). FIN 48 establishes a single model to address accounting for
uncertain tax positions. FIN 48 clarifies the accounting for income taxes by prescribing a minimum recognition threshold a tax position is required to meet before being

recognized in the financial statements. FIN 48 also provides guidance on derecognition, measurement classification, interest and penalties, accounting in
interim periods, disclosure and transition. The Company adopted the provisions of FIN 48 on January 1, 2007.

The Company is subject
to income taxes in the United States and ten foreign countries, and on occasion, we have been subject to corporate income tax audits. In determining the amount of income tax liabilities we make estimates of the results of future examinations of our
income tax returns by taxing authorities. We believe that we have adequately provided for in our financial statements for additional taxes that we estimate may result from these examinations. If these amounts exceed our estimates, reversal of the
reserves would result in the recognition of tax benefits in the period in which we determine the liability is no longer necessary. If an ultimate tax assessment exceeds our estimate of tax liabilities, an additional charge to expense will result.

Comparison of Year 2007 and Year 2006

Revenues. Revenues increased by $32.8 million, or 11.2%, from $292.5 million in 2006 to $325.2 million in 2007. The increase in revenue during the year ended December 31, 2007 compared to the year ended
December 31, 2006 was due to increases in revenues in the communications networking and commercial systems markets of $29.5 million and $3.3 million, respectively.

Revenues in the communications networking market increased in the year ended December 31, 2007 compared to the year ended December 31, 2006 due primarily to the addition of media server business and MCPD
revenues. Revenues also increased due to increased wireless revenues partially offset by decreases in the IP networking and messaging submarket. In the fourth quarter of 2007 our wireless business increase was driven in part by some acceleration of
customer demand into the fourth quarter.

Revenues in the commercial systems market increased in the year ended December 31, 2007
compared to the year ended December 31, 2006, primarily due to increases within the test and measurement submarket. The increase in revenues from the test and measurement submarket was attributable to design wins that have ramped into
production in the latter half of 2006.

Given the dynamics of these markets, we experience general fluctuations in the percentage of
revenue attributable to each market and, as a result, the quarter to quarter and year to year comparisons of our markets often are not indicative of overall economic trends affecting the long-term performance of our markets.

From a geographic perspective, for the year ended December 31, 2007 compared to the same period in 2006 the percentage of non-US revenues by
delivery destination increased as a percentage of total revenues. Revenues as measured by destination in the Asia Pacific region increased by $36.8 million while EMEA revenues decreased by $8.7 million. This was primarily due to existing
multinational customers requesting the delivery of products directly into the Asia Pacific region and decreased revenues attributable to our EMEA region associated with our wireless infrastructure products. For the year ended December 31, 2007
revenues from North America increased by $4.6 million compared to the same period in 2006. This increase was due to primarily to the addition of media server business revenues.

Gross margins as a percentage of revenues were 22.1% and 27.0% for 2007 and 2006, respectively. The decrease in gross margin as a percentage of revenues
for the year ended December 31, 2007 compared to the same period in 2006 was primarily attributable to amortization of purchased technology of $15.0 million. We reclassified this amortization in 2007 to cost of sales based on our view that the
intangibles are associated with product costs and our revenue-generating process. Amortization of purchased technology for prior periods was considered immaterial and has not been adjusted. This decrease was also due to product mix in our
communications and commercial markets, increased excess and obsolescence inventory charges and costs associated with the remaining transitions from our North Carolina manufacturer.

Research and Development. R&D expenses in 2007 consisted primarily of salary, bonuses and
benefits for product development staff, and cost of design and development supplies and equipment, net of reimbursements for non-recurring engineering services. R&D expenses increased $4.8 million, or 11.4%, from $41.5 million in 2006 to $46.2
million in 2007. The increase for the year ended December 31, 2007 compared to the same period in 2006 was primarily associated with the addition of our media server business partially offset by lower engineering headcount due to restructurings
done during the year to integrate our media server business. The increase was also due to an additional $1.0 million of stock-based compensation expense.

Selling, General, and Administrative. SG&A expenses in 2007 consisted primarily of salary, commissions, bonuses and benefits for sales, marketing, executive, and administrative personnel, as well as
professional services and costs of other general corporate activities. SG&A expenses increased $8.5 million, or 21.7%, from $39.3 million in 2006 to $47.9 million in 2006. The increase for the year ended December 31, 2007 compared to the
same period in 2006 was primarily associated with higher sales and marketing headcount as we invested in the infrastructure to sell our standards-based products. The increase was also due to the addition of our media server business as well as an
additional $2.1 million of stock-based compensation expense.

Stock-based Compensation Expense. Stock-based compensation expense for
the year ended December 31, 2007 consisted of amortization of stock-based compensation associated with stock options, restricted stock and ESPP shares unvested and outstanding on January 1, 2006 and new stock options, restricted stock and
ESPP shares granted for the year ended December 31, 2007. During the year ended December 31, 2007, the Company incurred $9.9 million in stock-based compensation. During the year ended December 31, 2006, we incurred $6.6 million in
stock-based compensation expense.

We recognized stock-based compensation expense as follows (in thousands):

Deferred Compensation Expense. On September 1, 2006, all outstanding Convedia stock
options vested and were considered exercised immediately. The proceeds of which were distributed as follows: 75% of the purchase price per share less the exercise price was paid to the option holder at closing and the remaining 25% will be paid in
full to those Convedia employees still employed by RadiSys after one year of service. The 75% paid at the time of the acquisition is included in the purchase price and is allocated to goodwill. The remaining 25% is recorded as deferred compensation
and amortized through the Consolidated Statement of Operations for the life of the asset (one year). Pursuant to the purchase agreement any forfeitures are reallocated to the remaining Convedia employees. We paid the remaining 25% of the proceeds
calculation on September 30, 2007.

We recognized deferred compensation expense as follows (in thousands):

Intangible Assets Amortization. Intangible assets consisted of purchased technology,
patents and other identifiable intangible assets. Intangible assets amortization expense was $4.4 million and $6.2 million in 2007

and 2006, respectively. Intangible assets amortization decreased primarily due to the amortization of purchased technology which was included with cost of
sales. We reclassified certain amortization in 2007 to cost of sales based on our view that the intangibles are associated with product costs and our revenue-generating process. Amortization of purchased technology for prior periods was considered
immaterial and was not adjusted. We perform reviews for impairment of the purchased intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Restructuring and Other Charges. We evaluate the adequacy of the accrued restructuring and other charges on a quarterly basis. As a result, we
record certain reclassifications and reversals to the accrued restructuring and other charges based on the results of the evaluation. The total accrued restructuring and other charges for each restructuring event are not affected by
reclassifications. Reversals are recorded in the period in which we determine that expected restructuring and other obligations are less than the amounts accrued. Tables summarizing the activity in the accrued liability for each restructuring event
are contained in Note 11 of the Notes to the Consolidated Financial Statements. During 2007 and 2006, we recorded restructuring and other charges and reversals as described below.

Fourth Quarter 2006 Restructuring.During the fourth quarter of 2006, we initiated a restructuring plan that included the elimination of 12
positions primarily supporting our contract manufacturing operations as a result of the termination of our relationship with one of our contract manufacturers in North America. The restructuring plan also includes closing our Charlotte office. In
2006, we incurred severance and other employee-related separation costs of $329,000 as a result of this restructuring event. In 2007 we incurred additional severance and other employee-related separation costs of $127,000 offset by reversals of
$204,000, respectively, associated with three employees who found new positions within the Company. In addition, we incurred a cost of $64,000 associated with the closing of the Charlotte office during the third quarter of 2007 offset by $7,000 of
amortization.

First Quarter 2007 Restructuring.During the first quarter of 2007, we incurred employee-related expenses associated
with certain engineering realignments. The costs incurred in this restructuring event are associated with employee termination benefits, including severance and medical benefits. All restructuring activities were completed by September 30,
2007. In 2007, we incurred $158,000 of employee-related, net expenses.

Second Quarter 2007 Restructuring.During the second quarter
of 2007, we incurred employee-related expenses associated with skill set changes for approximately 20 employees. The changes involved creating an integrated structure with our media server business along with some skill set changes in certain
selling, general and administrative and engineering groups. The costs incurred in this restructuring event include employee severance and medical benefits. In 2007, we incurred $1.3 million of employee-related, net expenses.

Interest Expense. Interest expense included interest incurred on the convertible notes. Interest expense decreased $54,000, or 3.1%, from $1.7
million in 2006 to $1.7 million in 2007. The decrease in the interest expense in 2007 compared to 2006 is due to the payment of the remaining principal amount of the convertible subordinated notes in August of 2007.

Interest Income. Interest income decreased $2.9 million, or 31.5%, from $9.3 million in 2006 to $6.4 million in 2007. Interest income decreased
primarily due to our decreased cash and cash equivalents and investments balance associated with the purchase of Convedia and MCPD.

Other Income (Expense), Net.Other income (expense), net, primarily includes foreign currency exchange gains and losses. Other income (expense), net, was $(169,000) in 2007 compared to $851,000 in 2006. Foreign currency exchange rate
fluctuations resulted in a net loss of $116,000 in 2007 compared to a net gain of $96,000 in 2006. The change in the foreign currency exchange rate fluctuations for the year is due to changes in the Canadian Dollar, Euro, Israeli Shekel, Japanese
Yen and Chinese Yuan relative the U.S. Dollar.

##### Table of Contents

In addition to foreign currency exchange rate fluctuations, other income (expense) included gains
(losses) associated with our executive deferred compensation plan of $(52,000) and $362,000 for 2007 and 2006, respectively. For 2006, other income (expense), net also included a $400,000 gain associated with a supplier settlement.

Income Tax Provision. We recorded tax benefits of $6.0 million and $746,000 for the years ended December 31, 2007 and 2006, respectively. Our
effective tax rate for the year ended 2007 was (25.5%) compared to (5.4%) for the year ended December 31, 2006. The Companys current effective tax rate differs from the statutory rate primarily due to the impact of stock option
expense, research and development tax credits generated in 2007, the revaluation of certain net deferred tax assets due to changes in foreign currency exchange rates and taxes on foreign income that differ from U.S. tax rate.

On December 20, 2006, President Bush signed the Tax Relief and Health Care Act of 2006 (the Tax Relief Act), which extended the research
and development tax credit. Under the Tax Relief Act the research and development tax credit was retroactively reinstated to January 1, 2006 and is available through December 31, 2007. We have recorded federal and Canadian research and
development credits of approximately $770,000 and $1.8 million, respectively, for the year ended 2007.

2007, we used $6.3 million and $5.7 million, respectively, for capital expenditures. During the year ended December 31, 2008 capital expenditures were primarily associated with integrating the MCPD business as well as various purchases made to
upgrade our internal infrastructure. During the year ended December 31, 2007 capital expenditures were primarily associated with integrating the media server business and the MCPD business, upgrading our internal infrastructure as well as
increasing manufacturing capabilities in our Hillsboro facility.

During the years ended December 31, 2008 and 2007, we received $5.2
million and $4.8 million, respectively, in proceeds from the issuance of common stock through the Companys stock compensation plans.

Changes in foreign currency rates impacted beginning cash balances during 2008 by ($301,000). Due to the Companys international operations where transactions are recorded in functional currencies other than the U.S. Dollar, the
effects of changes in foreign currency exchange rates on existing cash balances during any given periods results in amounts on the Consolidated Statements of Cash Flows that may not reflect the changes in the corresponding accounts on the
Consolidated Balance Sheets.

As of December 31, 2008 and 2007 working capital was $66.1 million and $61.8 million, respectively.
Working capital increased by $4.3 million due primarily to a net decrease in current liabilities that was greater than the decrease in our current assets. The decrease in current assets was due primarily to the reclassification of our ARS to
long-term along with a decrease in accounts receivable of $25.0 million. These decreases were offset by an increased cash balance driven by cash flow from operations totaling $34.9 million. The decrease in current liabilities resulted from the
repurchase of our 2023 convertible senior notes for $97.5 million and a decrease in accounts payable totaling $15.6 million. These decreases were both offset by borrowings on our revolving line of credit.

We currently hold investments in ARS, which are highly rated debt instruments with a long-term nominal
maturity. The majority of our ARS represent interests in collateralized debt obligations supported by pools of government-backed student loans with S&P AAA ratings or Moodys Aaa ratings at the time of purchase. These investments had
previously been classified as available-for-sale investments. Available-for-sale securities are recorded at fair value, and unrealized holding gains and losses are recorded, net of tax, as a separate component of accumulated other comprehensive
income.

Between December 31, 2007 and February 7, 2008, we sold at par value $10.0 million in ARS of the total ARS balance of
$72.8 million which was held at December 31, 2007. During the first quarter of 2008, due to liquidity issues experienced in the global credit and capital markets, our remaining portfolio of ARS experienced multiple failed auctions as the amount
of securities submitted for sale exceeded the amount of purchase orders. An auction failure, which is not a default in the underlying debt instrument, occurs when there are more sellers than buyers at a scheduled interest rate auction date and
parties desiring to sell their auction rate securities are unable to do so. When an auction fails, the interest rate is adjusted according to the provisions of the associated security agreement, which may result in an interest rate that is higher
than the interest rate the issuer pays in connection with successful auctions. We will not be able to liquidate the investments until a successful auction occurs, a buyer is found outside the auction process, the securities are called or refinanced
by the issuer, or the securities mature. Due to the uncertainty of when we will be able to liquidate the investments, we reclassified the investments to long-term assets during the first quarter of 2008 and continue to hold our ARS as such.

During August of 2008, UBS AG, the parent company of the securities firm with which we hold our ARS, announced an offer to its
clients holding ARS. Under this offer, UBS AG would issue Auction Rate Securities Rights to us. Subsequently, during the fourth quarter of 2008, we accepted the offer from UBS AG, which gave us a non-transferable right to require the bank to
purchase, at par value, $62.7 million in ARS at any time between June 30, 2010 and June 30, 2012. The agreement allows UBS AG to purchase the ARS before June 30, 2010, but it is under no obligation to do so. If the bank has not
purchased the investments by June 30, 2010, we plan to exercise our non-transferable right to require the purchase at that time. In addition, under the terms of the offer, we also became eligible for a demand line of credit of up to 75% of the
market value of our ARS until the time of purchase, which is described in greater detail below. As of December 31, 2008, we had drawn $39.5 million under the terms of this agreement.

As a result of accepting the settlement right from UBS, in accordance with our policy as well as the provisions of SFAS No. 115, we transferred our
ARS from available-for-sale to trading securities during the fourth quarter of 2008, as we plan to sell them on June 30, 2010. At the time of transfer we recognized in earnings an unrealized holding loss in the amount of $11.5 million. The loss
was based on our own estimated valuation of the ARS as of December 31, 2008. Concurrently, we recognized a gain in the amount of $11.1 million, associated with the settlement right accepted from UBS. This gain was due to the Company electing
the fair value option under SFAS No. 159 The Fair Value Option for Financial Assets and Financial Liabilitiesupon initial recognition of this right.

The fair value of the settlement right and ARS were derived based on estimated discounted cash flows. We considered various inputs to estimate cash flows
for our ARS at December 31, 2008, including the estimated time to allow the market for ARS to recover, projected estimates of future interest income generated from the investments, as well premiums designed to account for liquidity and credit
risks associated with our ARS holdings. For our non-transferable right, we considered inputs such as the issuers credit quality, expected term, and estimates of future risk free rates. Our valuation of both components of our ARS are contingent
upon the financial viability of our investment bank and accordingly, we have assigned a credit risk component to our valuations based on market data available at the time of valuation. However, if market conditions change and our investment bank is
unable to fulfill its commitment, we could incur an impairment charge on our settlement right, which would materially and adversely affect our operating results and overall financial condition. Additionally, the inputs used in our valuation are
based on managements estimates at the time of valuation and require significant judgment. If any of these inputs vary or market conditions change significantly, actual results may differ and our overall financial condition and operating
results may be materially and adversely affected.

Lines of Credit

Silicon Valley Bank

On August 7,
2008, we entered into a secured revolving line of credit agreement (the Agreement) with Silicon Valley Bank, as the Lender. The Agreement provides us with a two-year secured revolving credit facility of $30.0 million, which is subject to
a borrowing base and secured by our accounts receivable. Borrowings under the Agreement will bear interest at the prime rate, which was 3.25% at December 31, 2008, or the LIBOR rate, which was 0.44% at December 31, 2008, plus 1.25%, with
either interest rate determined upon our election. We are required to make interest payments monthly. We are further required to pay a commitment fee equal to 0.08% of the $30.0 million maximum borrowing limit on an annual basis, and to pay
quarterly in arrears an unused facility fee in an amount equal to 0.375% per year of the unused amount of the facility. In addition, the credit facility provides sub-facilities for letters of credit and foreign exchange contracts to be issued
on our behalf.

The Agreement requires us to make and maintain certain financial covenants, representations, warranties and other
agreements that are customary in credit agreements of this type. The Agreement requires us to maintain a minimum current ratio (current assets divided by the sum of current liabilities less deferred income plus the amount of outstanding
advances and letters of credit) of 1.5 as of December 31, 2008 and quarterly periods thereafter. Additionally, any quarterly EBITDA (earnings before interest, taxes, depreciation, amortization, stock based compensation and goodwill impairment
charges, as defined in the Agreement) loss may not exceed $2.5 million in any one quarter, and quarterly EBITDA may not be negative for any two consecutive quarters for the duration of the Agreement. Further, our EBITDA may not be negative for the
year ended December 31, 2008. For quarterly periods beginning after January 1, 2009, we must maintain a positive rolling four quarter EBITDA. In addition, capital expenditures may not exceed $12.0 million in any fiscal year. During the
fourth quarter of 2008, we amended the Agreement. The amendment included a one-time exclusion for the goodwill impairment charge recognized in the fourth quarter of 2008.

Amounts borrowed and repaid are available for re-borrowing during the term of the facility. Outstanding amounts are due in full on the maturity date of August 6, 2010. Upon the occurrence of certain events of
default specified in the Agreement, amounts due under the Agreement may be declared immediately due and payable.

As of December 31,
2008, we had no outstanding balances on the line of credit or letters of credit issued on our behalf.

UBS

As noted above, in August 2008, UBS AG, the parent company of the securities firm with which we hold our ARS, announced an offer to its clients
holding ARS. Under this offer, UBS AG would issue Auction Rate Securities Rights to us. These rights would allow us to sell the ARS held in our accounts with UBS Financial Services, Inc. or UBS Securities LLC to UBS AG at par value during the period
beginning June 30, 2010 and ending July 2, 2012. Under this offer, we would also be entitled to receive no net cost loans from UBS AG or its affiliates for up to 75% of the fair value of our ARS.

We accepted the offer and entered into a Credit Line Agreement (the Credit Line), including an Addendum to Credit Line Account Application
and Agreement, with UBS Bank USA. In addition, on December 12, 2008 we borrowed approximately $39.8 million under the Credit Line. On December 15, 2008, we used a portion of the proceeds to pay in full the outstanding principal balance of
approximately $20.0 million under our secured revolving line of credit agreement with Silicon Valley Bank. The amount of interest we will pay under the Credit Line is intended to equal the amount of interest we would receive with respect to our ARS
and is currently set at T-Bill plus 1.20%. The borrowings under the Credit Line are payable upon demand; however, UBS Bank USA or its affiliates are required to provide to us alternative financing on substantially similar terms, unless the demand
right was exercised as a result of certain specified events or the customer relationship between UBS Bank USA and us is terminated for cause by UBS Bank USA. As of December 31, 2008, we had an outstanding balance on the Credit Line in the
amount of $39.5 million.

2023 Convertible Senior Notes

During November 2003, we completed a private offering of $100 million aggregate principal amount of 1.375% convertible senior notes due November 15,
2023 (the 2023 convertible senior notes) to qualified institutional buyers.

During the first quarter of 2008, we repurchased
$52.5 million aggregate principal amount of the 2023 convertible senior notes, with an associated discount of $1.3 million. We repurchased the notes in the open market for $51.1 million and, as a result, recorded a gain of $68,000.

During the second quarter of 2008, we repurchased $10.0 million aggregate principal amount of the 2023 convertible senior notes, with an associated
discount of $240,000. We repurchased the notes in the open market for $9.8 million and, as a result, recorded a net loss of $31,000.

On
November 15, 2008, the holders of the 2023 convertible senior notes required us to purchase, in cash, the entire remaining aggregate amount outstanding, together with accrued and unpaid interest as of this date. As such, we repurchased
$37.5 million remaining aggregate principal amount of the 2023 convertible senior notes, with an associated discount of $874,000. We repurchased the notes in the open market for $37.5 million and, as a result, recorded a net loss of $874,000. As of
December 31, 2008, the 2023 convertible senior notes were fully retired.

2013 Convertible Senior Notes

On February 6, 2008, we offered and sold in a public offering pursuant to the shelf registration statement $55.0 million aggregate principal amount
of our 2013 convertible senior notes. Interest on the 2013 convertible senior notes is payable semi-annually, in arrears, on each August 15 and February 15, beginning on August 15, 2008, to the holders of record at the close of
business on the preceding August 1 and February 1, respectively. The 2013 convertible senior notes mature on February 15, 2013. Holders of the 2013 convertible senior notes may convert their notes into a number of shares of our common
stock determined as set forth in the indenture governing the notes at their option on any day to and including the business day prior to the maturity date. The 2013 convertible senior notes are initially convertible into 76.7448 shares of our common
stock per $1,000 principal amount of the notes (which is equivalent to a conversion price of approximately $ 13.03 per share), subject to adjustment upon the occurrence of certain events. Upon the occurrence of a fundamental change, holders of
the 2013 convertible senior notes may require us to repurchase some or all of our notes for cash at a price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest, if any. In addition, if certain
fundamental changes occur, we may be required in certain circumstances to increase the conversion rate for any 2013 convertible senior notes converted in connection with such fundamental changes by a specified number of shares of our common stock.
The 2013 convertible senior notes are our general unsecured obligations and rank equal in right of payment to all of our existing and future senior indebtedness, including our 2023 convertible senior notes, and senior in right of payment to our
future subordinated debt. Our obligations under the 2013 convertible senior notes are not guaranteed by, and are effectively subordinated in right of payment to all existing and future obligations of, our subsidiaries and are effectively
subordinated in right of payment to our future secured indebtedness to the extent of the assets securing such debt.

In connection with the
issuance of the 2013 convertible senior notes, we entered into a capped call transaction with a hedge counterparty. The capped call transaction is expected to reduce the potential dilution upon conversion of the 2013 convertible senior notes in the
event that the market value per share of our common stock, as measured under the terms of the capped call transaction, at the time of exercise is greater than the strike price of the capped call transaction of approximately $13.03, which corresponds
to the initial conversion price of the 2013 convertible senior notes and is subject to certain adjustments similar to those contained in the notes. If, however, the market value per share of our common stock exceeds the cap price of the capped call
transaction of $23.085, as measured under the terms of the capped call transaction, the dilution mitigation under the capped call transaction will be limited, which means that there would be dilution to the extent that the then market value per

##### Table of Contents

share of our common stock exceeds the cap price of the capped call transaction. The cost of the capped call transaction was approximately $10.2 million and
was recorded as a charge to shareholders equity.

During the fourth quarter of 2008, we repurchased $5.0 million aggregate principal
amount of the 2013 convertible senior notes, with associated unamortized issuance costs of $196,000. We repurchased the notes in the open market for $3.1 million and, as a result, recorded a net gain of $1.7 million.

As of December 31, 2008, we had outstanding 2013 convertible senior notes with a face value and fair value of $50.0 million and $26.9 million,
respectively.

Convertible Subordinated Notes

During August 2000, we completed a private offering of $120 million aggregate principal amount of 5.5% convertible subordinated notes due to qualified institutional buyers. From 2000 to 2006, we repurchased $117.7
million in aggregate principal amount of the convertible subordinated notes, with an associated unamortized discount of $2.4 million. We repurchased the notes for $106.7 million and, as a result recorded a gain of $8.5 million. We paid the remaining
balance of $2.4 million at maturity on August 15, 2007.

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

In addition to the above, as discussed in Note 18 of the Notes to the Consolidated Financial Statements, we have approximately $2.4 million associated
with unrecognized tax benefits and related interest and penalties. These liabilities are primarily included as a component of other long-term liabilities in our Consolidated Balance Sheet as we do not anticipate that settlement of the
liabilities will require payment of cash within the next twelve months. We are not able to reasonably estimate when we would make any cash payments required to settle these liabilities, but do not believe that the ultimate settlement of our
obligations will materially affect our liquidity.

Off-Balance Sheet Arrangements

We do not engage in any activity involving special purpose entities or off-balance sheet financing.

Shelf Registration Statement

On October 26, 2007, we filed an unallocated shelf registration statement on Form S-3 for the offering from time to time of up to $150 million in securities consisting of common stock, preferred stock, depositary shares, warrants, debt
securities or units consisting of one or more of these securities. The SEC declared the shelf registration statement effective on November 7, 2007. Except as may be stated in a prospectus supplement for

##### Table of Contents

any particular offering, we intend to use the net proceeds from the sale of any securities for general corporate purposes, which may include acquiring
companies in our industry and related businesses, repaying existing debt, providing additional working capital and procuring capital assets.

On February 6, 2008, we offered and sold in a public offering pursuant to the shelf registration statement $55.0 million aggregate principal amount of 2013 convertible senior notes. During the fourth quarter of 2008, we repurchased
$5.0 million aggregate principal amount of the 2013 convertible senior notes, with associated unamortized issuance costs of $196,000. We repurchased the notes in the open market for $3.1 million and, as a result, recorded a net gain of $1.7 million.
As such, we have $100.0 million remaining capacity under this shelf registration statement.

Liquidity Outlook

We believe that our current cash, cash equivalents and investments, net, amounting to $125.2 million at December 31, 2008, of which $51.2 million
consisted of ARS, the cash generated from operations and our line of credit facility will satisfy our short and long-term expected working capital needs, capital expenditures, stock repurchases, other liquidity requirements associated with our
existing business operations even if we are required to hold our ARS until maturity. Capital expenditures are expected to range from $1.0 million to $1.5 million per quarter.

Recent Accounting Pronouncements

See Note 1 to the Consolidated Financial Statements for a full description of recent accounting pronouncements including the respective expected dates of adoption and effects on results of operations and financial condition.



|Item 7A. | Quantitative and Qualitative Disclosures about Market Risk
|-------- | ----------------------------------------------------------

We are exposed to market risk from changes in interest rates, foreign currency exchange rates, and equity trading prices, which could affect our financial position and results of operations.

Interest Rate Risk. We invest excess cash in debt instruments of the U.S. Government and its agencies, and those of high-quality corporate
issuers. We attempt to protect and preserve our invested funds by limiting default, market, and reinvestment risk. Investments in both fixed rate and floating rate interest earning instruments carry a degree of interest rate risk. Fixed rate
securities may have their fair value adversely affected due to a rise in interest rates while floating rate securities may produce less income than expected if interest rates decline. Due to the short duration of most of the investment portfolios,
an immediate 10% change in interest rates would not have a material effect on the fair value of our investment portfolio. Additionally, the interest rate changes affect the fair market value but do not necessarily have a direct impact on our
earnings or cash flows. Therefore, we would not expect our operating results or cash flows to be affected, to any significant degree, by the effect of a sudden change in market interest rates on the securities portfolio. The estimated fair value of
our interest bearing investments at December 31, 2008 and 2007 was $66.2 million and $95.1 million, respectively. The effect of an immediate 10% change in interest rates would not have a material effect on our operating results or cash flows.

Foreign Currency Risk. We pay the expenses of our international operations in local currencies, namely, the Euro, British
Pound Sterling, New Shekel, Japanese Yen, Chinese Yuan, Canadian Dollar and Malaysian Ringgit. The international operations are subject to risks typical of an international business, including, but not limited to: differing economic conditions,
changes in political climate, differing tax structures, foreign exchange rate volatility and other regulations and restrictions. Accordingly, future results could be materially and adversely affected by changes in these or other factors. We are also
exposed to foreign exchange rate fluctuations as the balance sheets and income statements of our foreign subsidiaries are translated into U.S. Dollars during the consolidation process. Because exchange rates vary, these results, when translated, may
vary from expectations and adversely affect overall expected profitability. Foreign currency exchange rate fluctuations resulted in a net



50

##### Table of Contents

gain of $193,000 for the year ended December 31, 2008, a net loss of $116,000 for the year ended December 31, 2007 and a net gain of $96,000 for
the year ended December 31, 2006.

Based on our policy, we have established a foreign currency exposure management program which uses
derivative foreign exchange contracts to address nonfunctional currency exposures that are expected to be settled in one year or less. During the first quarter of 2008, in order to reduce the potentially adverse effects of foreign currency exchange
rate fluctuations, we began to enter into forward exchange contracts. These hedging transactions primarily limit our exposure to changes in the U.S. Dollar/Canadian Dollar exchange rate and as of December 31, 2008 we had $5.7 million in
aggregate hedge contracts outstanding, which mature over the next 11 months.

Holding other variables constant, a 10% adverse fluctuation,
in relation to our hedge positions, of the U.S. Dollar relative to the Canadian Dollar would result in an increase of $625,000 to our current hedge liability and the total hedge liability as of December 31, 2008, would be $1.8 million. A
10% favorable fluctuation, in relation to our hedge positions, of the U.S. Dollar relative to the Canadian Dollar would result in the reversal of an $622,000 from our current hedge liability and the total hedge liability as of December 31,
2008, would be $584,000. We do not expect a 10% fluctuation to have any impact on our operating results as the underlying hedged transactions will move in an equal and opposite direction.

Convertible Notes.The fair value of the convertible senior notes is sensitive to interest rate changes as well as changes in our stock price.
Interest rate changes would result in an increase or decrease in the fair value of the convertible notes due to differences between market interest rates and rates in effect at the inception of the obligation. Fluctuations in our stock price would
result in an increase or decrease in the fair value of the convertible notes due to the value of the notes derived from the conversion feature. Unless we elect to repurchase our senior convertible notes in the open market, changes in the fair value
of the senior convertible notes have no impact on our cash flows or Consolidated Financial Statements. The estimated fair value of the 2013 convertible senior notes was $26.9 million at December 31, 2008.

Second Quarter 2008 Restructuring.During the second quarter of 2008, we incurred employee-related
expenses associated with efforts to manage engineering spend to levels which align with targeted profitability as well as refocus the Companys skill sets in new product deployment and provide enhanced service and support to existing customers.
In 2008 we incurred $598,000 of employee-related expenses, net.

Fourth Quarter 2008 Goodwill Impairment Charge. During the fourth
quarter of 2008, we incurred a goodwill impairment charge. In accordance SFAS 142, we completed our annual goodwill impairment test in September 2008, at which time no impairment was indicated. At the end of the fourth quarter of 2008, we reviewed
our continued low stock price, which was considered a triggering event for re-testing goodwill impairment, and ultimately concluded that its difference from our book value per share indicated impairment. As such, we impaired our entire goodwill
balance which resulted in a charge of $67.3 million.

MANAGEMENTS REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules
13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Companys internal control over financial reporting is a process designed to provide reasonable assurance regarding reliability of financial reporting and the preparation
and fair presentation of published financial statements for external purposes in accordance with generally accepted accounting principles.

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.

Management
assessed the effectiveness of the Companys internal control over financial reporting as of December 31, 2008. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO) in Internal ControlIntegrated Framework. Based on our assessment, we conclude that, as of December 31, 2008, the Companys internal control over financial reporting is effective based on those criteria 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.

The effectiveness of internal control over financial reporting as of December 31, 2008, has been audited by KPMG, LLP, the independent registered
public accounting firm who also audited the Companys Consolidated Financial Statements included in this Item 8, as stated in the report which appears on page 54 hereof.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

RadiSys Corporation:

We have audited RadiSys Corporations internal control over financial reporting as of December 31, 2008, based on criteria established inInternal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). RadiSys Corporations management is responsible for maintaining effective internal control over financial
reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on Internal Control over Financial Reporting. Our responsibility is to express an
opinion on the Companys internal control over financial reporting based on our audit.

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

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

Because of 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.

In our opinion, RadiSys Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31,
2008, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of RadiSys Corporation and subsidiaries as of December 31,
2008 and 2007, and the related consolidated statements of operations, changes in shareholders equity and comprehensive income (loss), and cash flows for each of the years in the three-year period ended December 31, 2008, and our report
dated March 6, 2009 expressed an unqualified opinion on those consolidated financial statements.

are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of RadiSys
Corporation and subsidiaries as of December 31, 2008 and 2007, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2008, in conformity with U.S. generally accepted

RADISYS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note
1Significant Accounting Policies

Basis of Presentation

RadiSys Corporation (RadiSys or the Company) was incorporated in March 1987 under the laws of the State of Oregon for the purpose
of developing, producing and marketing computer system (hardware and software) products for embedded computer applications in the manufacturing automation, medical, transportation, telecommunications and test equipment marketplaces. The Company has
evolved into a leading provider of embedded systems for compute, data processing and network-intensive applications to original equipment manufacturers (OEM) within the communications networking and commercial systems markets.

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All inter-company accounts and transactions have been properly eliminated in consolidation.

Management Estimates

The Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires management to make estimates and judgments that may affect the
amounts reported in its Consolidated Financial statement and accompanying notes. Current volatile economic conditions require additional judgment in the establishment of reserves such as the Companys allowance for doubtful accounts and
inventory valuation allowance. Actual results may differ from these estimates under different assumptions or conditions.

Reclassifications

Certain reclassifications have been made to amounts in prior years to conform to current year
presentation.

Revenue Recognition

The Company recognizes revenue when the earnings process is complete, as evidenced by the following revenue recognition criteria: an agreement with the customer, fixed pricing, transfer of title and risk of loss and
customer acceptance, if applicable, and that the collectability of the resulting receivable is reasonably assured. When a sales arrangement contains multiple elements, such as hardware and software products, licenses and/or services, the Company
allocates revenue to each element based on its relative fair value, or for software, based on vendor specific objective evidence (VSOE) of fair value. In the absence of fair value for a delivered element, the Company first allocates
revenue to the fair value of the undelivered elements and the residual revenue to the delivered elements. Where the fair value for an undelivered element cannot be determined, the Company defers revenue for the delivered elements until the
undelivered elements are delivered. The Company limits the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services or subject to customer-specified return or refund
privileges.

Hardware

Revenue from hardware products where software is incidental is recognized in accordance with Staff Accounting Bulletin (SAB) 104. Under the Companys standard terms and conditions of sale, the Company transfers title and
risk of loss to the customer at the time product is shipped to the customer and revenue is recognized accordingly, unless customer acceptance is uncertain or significant obligations remain. The Company

reduces revenue for estimated customer returns for rotation rights as well as for price protection rights according to agreements with its distributors. The
amount of revenues derived from these distributors as a percentage of revenues was 15.2%, 9.9% and 3.4% for the years ended December 31, 2008, 2007 and 2006. The Company accrues the estimated cost of post-sale obligations for product
warranties, based on historical experience at the time the Company recognizes revenue. In addition, approximately 85% of the Companys unit volume is attributable to contract manufacturers.

The software content included in certain components of ATCA systems, certain MCPD products and Convedia Media Servers is considered to be more than
incidental and our ATCA arrangements generally include multiple elements such as hardware, technical support services as well as specified software upgrades or enhancements. As such, the revenue associated with these products is recognized in
accordance with Statement of Position (SOP) 97-2, Software Revenue Recognition.

Software royalties and licenses

Revenue from software royalties and licenses is recognized in accordance with SOP 97-2. Revenue from customers for prepaid,
non-refundable software royalties is recorded when the revenue recognition criteria have been met. Revenue for non-prepaid royalties is recognized at the time the underlying product is shipped by the customer paying the royalty. The Company
recognizes software license revenue at the time of shipment or upon delivery of the software master provided that the revenue recognition criteria have been met and VSOE exists to allocate the total fee to all undelivered elements of the
arrangement. The Company defers revenue on arrangements including specified software upgrades until the specified upgrade has been delivered.

Software maintenance

Software maintenance services are recognized as earned on the straight-line basis over the terms of
the contract in accordance with SOP 97-2. The fair value of the Companys post-contract support has been determined by renewal rates within the Companys support agreements as well as the actual amounts charged to customers for renewal of
their support services.

Engineering and other services

Engineering services revenue is recognized upon completion of certain contractual milestones and customer acceptance of the services rendered in
accordance with SOP 81-1, Accounting for Performance of Construction-Type and Certain Production-Type Contracts (SOP 81-1). Other services revenues include hardware repair services and custom software implementation projects. Hardware
repair services revenues are recognized when the services are complete. Software implementation revenues are recognized upon completion of certain contractual milestones and customer acceptance of the services rendered.

Deferred income

Deferred income
represents amounts received or billed for the following types of transactions:



| |  |  | Distributor salesCertain sales are made to distributors under agreements providing price protection and right of return on unsold merchandise. Revenue
and costs relating to such distributor sales are deferred until the product is sold by the distributor or return privileges and price protection rights terminate, at which time related estimated distributor resale revenue, estimated effects of
distributor price adjustments, and estimated costs are reflected in the Consolidated Statement of Operations.

distributors servicing the MCPD business. For the majority of these distributors, price adjustment programs were eliminated. For those distributors where significant price adjustment programs remain in place, the Company continues to defer revenue
until the distributors sell the merchandise.

Revenue reporting for these distributors is highly dependent on receiving pertinent and
accurate data from the Companys distributors in a timely fashion. Distributors provide periodic data regarding the product, price, quantity, and end customer when products are resold as well as the quantities of the Companys products
they still have in stock. The Company must use estimates and apply judgments to reconcile distributors reported inventories to its activities.

products is deferred until the future obligation is fulfilled.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Service salesCertain sales are made for products and related service where the fair value of the service cannot be determined. Revenues for such sales
are deferred until service obligations represent the only undelivered element, at which point revenues are recognized ratably over the requisite service period. The Company limits the amount of revenue recognition for delivered elements to the
amount that is not contingent on the future delivery of products or services or subject to customer-specified return or refund privileges.

Capitalized Software Development Costs

The Company does not capitalize internal software
development costs incurred in the production of computer software as the Company concluded it does not incur any material costs between the point of technological feasibility and general release of the product to customers in the future. As such
software development costs are expensed as R&D costs.

Shipping Costs

The Companys shipping and handling costs for product sales are included under cost of sales for all periods presented. For the years ended
December 31, 2008, 2007 and 2006 shipping and handling costs represented approximately 1% of cost of sales.

Cash and Cash
Equivalents

The Company considers all highly liquid investments purchased with an original or remaining maturity of three months or
less at the date of purchase to be cash equivalents in accordance with a Statement of Financial Accounting Standards (SFAS) No. 95 Statement of Cash Flows.

Investments

Auction rate
securities (ARS) are classified as long-term trading securities. Trading securities are recorded at fair value, and unrealized holding gains and losses are recognized in earnings. Historically, these investments were classified as
held-to-maturity with original maturities of more than three months but less than a year classified as short-term investments, and investments classified as held-to-maturity with original maturities more than a year classified as long-term
investments in the Consolidated Financial Statements.

The Companys investments consist of ARS. The Company classifies, at the date
of acquisition, its investments into categories in accordance with the provisions of SFAS No. 115, Accounting for Certain

Investments in Debt and Equity Securities. The Companys investments consisting of U.S. government notes and bonds are classified as
held-to-maturity as the Company has the positive intent and ability to hold those securities to maturity and are stated at amortized cost in the Consolidated Balance Sheets. The Companys investment policy requires that the held to maturity
investments, including cash and investments, not exceed a maximum weighted-average maturity of 18 months. In addition, the policy mandates that an individual investment must have a maturity of less than 36 months, with no more than 20% of the total
portfolio exceeding 24 months. Realized gains and losses, and interest and dividends on all securities are included in other expense, net and Interest income, in the Consolidated Statements of Operations.

Accounts Receivable

Trade
accounts receivable are stated net of an allowance for doubtful accounts. An allowance for doubtful accounts is maintained for estimated losses resulting from the inability of customers to make required payments. Management reviews the allowance for
doubtful accounts quarterly for reasonableness and adequacy. If the financial condition of the Companys customers were to deteriorate resulting in an impairment of their ability to make payments, additional provisions for uncollectible
accounts receivable may be required. In the event the Company determined that a smaller or larger reserve was appropriate, it would record a credit or a charge in the period in which such determination is made. In addition to customer accounts that
are specifically reserved for, the Company maintains a non-specific bad debt reserve for all customers based on a variety of factors, including the length of time receivables are past due, trends in overall weighted average risk rating of the total
portfolio, macroeconomic conditions, significant one-time events and historical experience. Typically, this non-specific bad debt reserve amounts to at least 1% of quarterly revenues. The Companys customers are concentrated in the technology
industry and the collection of its accounts receivable are directly associated with the operational results of the industry.

Inventories

Inventories are stated at the lower of cost or market, net of an inventory valuation allowance. Pursuant
to ARB 43 and SAB Topic 5-BB, our inventory valuation allowances establish a new cost basis for inventory. The Company uses a standard cost methodology to determine its cost basis for its inventories. The Company evaluates inventory on a quarterly
basis for obsolete or slow-moving items to ascertain if the recorded allowance is reasonable and adequate. Inventory is written down for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the
estimated net realizable value based upon assumptions about future demand and market conditions.

Long-Lived Assets

Long-lived assets, such as property and equipment and definite-life intangible assets are evaluated for impairment whenever events
or changes in circumstances indicate the carrying value of an asset may not be recoverable in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. The Company assesses the impairment of the
assets based on the undiscounted future cash flow the assets are expected to generate compared to the carrying value of the assets. If the carrying amount of the assets is determined not to be recoverable, a write-down to fair value is recorded.
Management estimates future cash flows using assumptions about expected future operating performance. Managements estimates of future cash flows may differ from actual cash flow due to, among other things, technological changes, economic
conditions or changes to the Companys business operations.

Goodwill represents the excess of cost over the assigned value of the net
assets in connection with all acquisitions. Goodwill is reviewed for impairment in accordance with SFAS No. 142 Goodwill and Other



63

RADISYS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Intangible Assets (SFAS No. 142). SFAS No. 142 requires goodwill to be tested for impairment at least annually and under certain
circumstances and will be written down when impaired. During the fourth quarter of 2008, the Company impaired its entire amount of previously recorded goodwill. Refer to Note 8, for details of the impairment analysis.

Intangible assets with estimable useful lives are amortized over their respective estimated lives to their estimated residual values, and reviewed for
impairment in accordance with SFAS No. 144.

Property and Equipment

Property and equipment is recorded at historical cost and generally depreciated or amortized on a straight-line basis according to the table below. In
certain circumstances where the Company is aware that an assets life differs from the general guidelines set forth in its policy, management adjusts its depreciable life accordingly, to ensure that expense is being recognized over the
appropriate future periods.

Ordinary maintenance and repair expenses are charged to income when incurred.

Accounting for Leases

The
Company leases most of its facilities, certain office equipment and vehicles under non-cancelable operating leases that expire at various dates through 2013, along with options that permit renewals for additional periods. Rent escalations are
considered in the determination of straight-line rent expense for operating leases. Leasehold improvements made at the inception of or during the lease are amortized over the shorter of the asset life or the lease term.

Asset Retirement Obligations

The Company leases most of its facilities under various operating leases, some of which contain clauses that require the Company to restore the leased facility to its original state at the end of the lease term. In accordance with SFAS
No. 143, Accounting for Asset Retirement Obligations and FIN 47, Accounting for Conditional Asset Retirement Obligations any identified material asset retirement obligation is initially measured at the fair value and
recorded as a liability with a corresponding increase in the carrying amount of the underlying property. Subsequently, the asset retirement obligation would accrete until the time the retirement obligation is expected to settle while the asset
retirement cost is amortized over the useful life of the underlying property. As of December 31, 2008 and 2007, the Company identified $75,000, of asset retirement obligations.

Accrued Restructuring and Other Charges

For the years ended December 31, 2008, 2007 and 2006 expenses associated with exit or disposal activities are recognized when probable and estimable under SFAS No. 146, Accounting for Costs Associated
with Exit or Disposal Activities for everything but severance. Because the Company has a history of paying severance benefits, the cost of severance benefits associated with a restructuring charge is recorded when such costs are probable and
the amount can be reasonably estimated. For leased facilities that were vacated, an amount equal to

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



the total future lease obligations from the date of vacating the premises through the expiration of the lease, net of any future sublease income, was
recorded as a part of restructuring charges.

Warranty

The Company provides for the estimated cost of product warranties at the time it recognizes revenue. Products are generally sold with warranty coverage
for a period of 24 months after shipment. On a quarterly basis the Company assesses the reasonableness and adequacy of the warranty liability and adjusts such amounts as necessary. Warranty reserves are included in other accrued liabilities in the
accompanying Consolidated Balance Sheets as of December 31, 2008 and December 31, 2007. See also Note 12Other Accrued Liabilitiesand Note 16Commitments and Contingencies.

Research and Development

Research, development and engineering costs are expensed as incurred. R&D expenses consist primarily of salary, bonuses and benefits for product development staff, and cost of design and development supplies and equipment, net of
reimbursements for non-recurring engineering services.

Income Taxes

The Company accounts for income taxes using the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities
for the expected future tax consequences of temporary differences between the financial statement carrying amounts and tax bases of assets and liabilities. Valuation allowances are established in accordance with SFAS No. 109, Accounting
for Income Taxes, to reduce deferred tax assets to the amount expected to more likely than not be realized in future tax returns. Tax law and rate changes are reflected in the period such changes are enacted. The Company recognizes
uncertain tax positions in accordance with FASB Interpretation No. 48 Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement 109 (FIN 48). The Company adopted the provisions of FIN 48 on
January 1, 2007. In accordance with FIN 48, the Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within its global operations in income tax expense. See Note 18Income Taxes.

Fair Value of Financial Assets and Liabilities

Effective January 1, 2008, the Company adopted SFAS No. 157, Fair Value Measurements (SFAS No. 157), except as it applies to the nonfinancial assets and nonfinancial
liabilities subject to FSP No. 157-2. SFAS No. 157 clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands
disclosures about fair value measurements. The three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is:

Level 1Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities
in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

Refer to Note 3, for details of the Companys financial assets and their respective
classification within the SFAS No. 157 hierarchy.

Comprehensive Income (Loss)

In accordance with SFAS No. 130, Reporting Comprehensive Income, the Company reports accumulated other comprehensive income (loss) in its
Consolidated Balance Sheets. Comprehensive income (loss) includes net income (loss), translation adjustments and unrealized gains (losses) on hedging instruments. The cumulative translation adjustments consist of unrealized gains (losses) in
accordance with SFAS No. 52, Foreign Currency Translation.

Stock-Based Compensation

On December 16, 2004, the Financial Accounting Standards Board issued SFAS No. 123 (revised 2004), Share-Based Payment (SFAS
123R). Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123R, using the modified prospective transition method and therefore has not restated results for prior periods. Under this transition
method, stock-based compensation expense for fiscal 2006 includes compensation expense for all stock-based compensation awards granted prior to, but not yet vested as of January 1, 2006, based on the grant date fair value estimated in
accordance with the original provision of SFAS No. 123, Accounting for Stock-Based Compensation (SFAS 123). Stock-based compensation expense for all stock-based compensation awards granted after January 1, 2006 is
based on the grant-date fair value estimated in accordance with the provisions of SFAS 123R. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award. Prior to the adoption of SFAS 123R,
the Company recognized stock-based compensation expense in accordance with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25). In March 2005, the SEC issued Staff Accounting
Bulletin No. 107 (SAB 107) regarding the SECs interpretation of SFAS 123R and the valuation of share-based payments for public companies. The Company has applied the provisions of SAB 107 in its adoption of SFAS 123R. See Note
19Employee Benefit Plans.

Net income (loss) per share

The Company computes earnings per share in accordance with SFAS No. 128, Earnings per Share. Accordingly, basic earnings per share
amounts are computed based on the weighted-average number of common shares outstanding. Diluted earnings per share amounts incorporated the incremental shares issuable upon assumed exercise of stock options, incremental shares associated with the
assumed vesting of restricted stock and the assumed conversion of the Companys convertible notes, as if the conversion to common shares had occurred at the beginning of the fiscal year and when such conversion would have the effect of reducing
earnings per share. When the conversion of the Companys convertible notes has the effect of reducing earnings per share earnings have also been adjusted for the interest expense on the convertible notes. See also Note 17Basic and
Diluted Income per Share.

Derivatives

During 2008, the Company began to enter into forward foreign currency exchange contracts to reduce the impact of foreign currency exchange risks where natural hedging strategies could not be effectively employed.

The Company does not hold or issue derivative financial instruments for trading purposes. The purpose of the Companys hedging
activities are to reduce the risk that the eventual cash flows of the underlying assets, liabilities and firm commitments will be adversely affected by changes in exchange rates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



All derivatives, including foreign currency exchange contracts are recognized on the balance sheet at
fair value. When specific criteria required by SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities (SFAS 133) have been met, changes in the fair values of hedge contracts related to anticipated
transactions are recorded in other comprehensive income (loss) rather than net income (loss) until the underlying hedged transaction affects net income. One of the criteria for this accounting treatment is that the forward foreign currency exchange
contract amount should not be in excess of specifically identified anticipated transactions. By their nature, estimates of anticipated transactions may fluctuate over time and may ultimately vary from actual transactions. If anticipated transaction
estimates or actual transaction amounts decrease below hedged levels, or when the timing of transactions change significantly, the Company would reclassify a portion of the cumulative changes in fair values of the related hedge contracts from other
comprehensive income (loss) to other income (expense) during the quarter in which the changes occur.

The Company adopted SFAS
No. 157; however the adoption did not have a material impact on results of operations. Refer to Note 15Hedgingfor further details of the Companys hedging activities.

Foreign currency translation

Assets and liabilities of international operations, using a functional currency other than the U.S. dollar, are translated into U.S. dollars at exchange rates as of December 31, 2008 and 2007. Income and expense accounts are translated
into U.S. dollars at the actual daily rates of exchange prevailing during the period. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are recorded as a separate component in
shareholders equity in accordance with SFAS No. 130. Foreign exchange transaction gains and losses are included in other expense, net, in the Consolidated Statements of Operations. Foreign currency exchange rate fluctuations resulted in a
net gain (loss) of $193,000, $(116,000), and $96,000 for the years ended December 31, 2008, 2007 and 2006, respectively.

Recent
Accounting Pronouncements

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and
Hedging Activitiesan amendment of FASB Statement No. 133, (SFAS 161). SFAS 161 requires enhanced disclosures about an entitys derivative and hedging activities, including (i) how and why an entity uses
derivative instruments, (ii) how derivative instruments and related hedged items are accounted for under SFAS 133, and (iii) how derivative instruments and related hedged items affect an entitys financial position, financial
performance, and cash flows. This standard becomes effective for the Company on January 1, 2009. Earlier adoption of SFAS 161 and, separately, comparative disclosures for earlier periods at initial adoption are encouraged. SFAS 161 requires
enhanced disclosures, which will be provided in the Companys 2009 Consolidated Financial Statements.

In December 2007, the FASB
issued SFAS No. 141 (revised 2007), Business Combinations, (SFAS 141R) and SFAS No. 160, Non-controlling Interests in Consolidated Financial Statements, an Amendment of ARB No. 51, (SFAS
160). These statements require significant changes in the accounting and reporting for business acquisitions and the reporting of non-controlling interests in subsidiaries. Among many changes under SFAS 141R, an acquirer will record 100% of
all assets and liabilities at fair value for partial acquisitions, contingent consideration will be recognized at fair value at the acquisition date with changes possibly recognized in earnings, and acquisition related costs will be expensed rather
than capitalized. SFAS 160 establishes new accounting and reporting standards for the non-controlling interest in a subsidiary. Key changes under the standard are that non-controlling interests in a subsidiary will be reported as part of equity,
losses allocated to a non-controlling interest can result in a deficit balance, and changes in ownership interests that do not result in a change of control are accounted for as equity transactions and, upon a loss of control, gain or loss is
recognized

and the remaining interest is remeasured at fair value on the date control is lost. SFAS 141R will apply prospectively to the Companys business
combinations occurring on or after January 1, 2009. The Company will also apply SFAS 160 beginning January 1, 2009. Adoption of these statements will affect the Companys accounting for any business acquisitions occurring after the
effective date and the reporting of any non-controlling interests in subsidiaries existing on or after the effective date.

In
May 2008, the FASB issued FASB Staff Position (FSP) No. APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement) (FSP APB
14-1). FSP APB 14-1 requires that issuers of such instruments separately account for the liability and equity components related to convertible debt instruments in a manner that will reflect the issuers nonconvertible debt borrowing rate
when interest expense is recognized in subsequent periods. Early adoption is not permitted and FSP APB 14-1 becomes effective for the Company on January 1, 2009. Based on preliminary analysis, the Company has determined that the new guidance
should only affect its 1.375% convertible senior notes due November 15, 2023 (the 2023 convertible senior notes). Although, the Companys 2023 convertible senior notes were retired as of December 31, 2008, the Company
will still be required to retrospectively apply FSP APB 14-1 in all periods presented that include the Companys 2023 convertible senior notes. As a result of this retrospective adoption, the Companys opening accumulated deficit
balance and paid in capital balance will increase, however the Company is still assessing the magnitude.

The Company has invested excess cash in auction rate securities (ARS) that have been
classified as trading securities. Historically these investments have been held as available-for-sale short-term investments, however, as explained below, due the circumstances surrounding the Companys ARS they were moved from short-term to
long-term in the first quarter of 2008, and reclassified to trading securities during the fourth quarter of 2008. In the past, available-for-sale securities were recorded at fair value, and unrealized holding gains and losses were recorded, net of
tax, as a separate component of accumulated other comprehensive income. For the years ended December 31, 2008, 2007 and 2006 the Company did not recognize any gains or losses on the sales of available-for-sale investments. At December 31,
2008 and 2007 the Company had no held-to-maturity investments. The Companys investment policy requires that the total investment portfolio, including cash and investments, not exceed a maximum weighted-average maturity of 18 months. In
addition, the policy mandates that an individual investment must have a maturity of less than 36 months, with no more than 20% of the total portfolio exceeding 24 months.

Between December 31, 2007 and February 7, 2008, the Company sold at par value $10.0 million
in ARS of the total ARS balance of $72.8 million which was held at December 31, 2007. During the first quarter of 2008, due to liquidity issues experienced in the global credit and capital markets, the Companys remaining portfolio of ARS
experienced multiple failed auctions as the amount of securities submitted for sale exceeded the amount of purchase orders. An auction failure, which is not a default in the underlying debt instrument, occurs when there are more sellers than buyers
at a scheduled interest rate auction date and parties desiring to sell their auction rate securities are unable to do so. When an auction fails, the interest rate is adjusted according to the provisions of the associated security agreement, which
may result in an interest rate that is higher than the interest rate the issuer pays in connection with successful auctions. The Company will not be able to liquidate the investments until a successful auction occurs, a buyer is found outside the
auction process, the securities are called or refinanced by the issuer, or the securities mature. Due to the uncertainty of when the Company will be able to liquidate the investments, the investments were reclassified to long-term assets during the
first quarter of 2008 and will continue to be held as such.

During August of 2008, the Companys investment bank announced it had
agreed to settlements with the Securities and Exchange Commission and other state regulatory agencies to restore liquidity to eligible holders of auction-rate securities. Subsequently, during the fourth quarter of 2008, the Company accepted an offer
from its investment bank which provided a non-transferable right to require the bank to purchase, at par value, $62.7 million in ARS at any time between June 30, 2010 and June 30, 2012. The agreement allows the investment bank to purchase
the ARS sooner than June 30, 2010, but is under no obligation to do so. If the bank has not purchased the investments by June 30, 2010, the Company plans to exercise its non-transferable right to require the purchase at that time. In
addition, under the terms of the offer, the Company also became eligible for a demand line of credit of up to 75% of the market value of our ARS until the time of purchase. As of December 31, 2008, the Company had drawn $39.5 million under the
terms of this agreement.

Consequently, in accordance with its policy as well as the provisions of SFAS No. 115, the Company
transferred its ARS from available-for-sale to trading securities during the fourth quarter of 2008, as it plans to sell them on June 30, 2010. As such, at the time of transfer, the Company recognized, in earnings, an unrealized holding loss,
in the amount of $11.5 million, based on its estimated valuation of its ARS at that time. Concurrently, the Company elected the fair value option under SFAS No. 159 The Fair Value Option for Financial Assets and Financial
Liabilitiesfor the non-transferable right, upon initial recognition. As such, the Company also recognized a gain in the amount of $11.1 million, based upon the value assigned to its non-transferable right from UBS. The net loss resulting
from these transactions is included in other income (expense), net, in the consolidated statements of operations for the year ended December 31, 2008.

The Company considered various inputs to estimate the fair value of its ARS at December 31, 2008, including the estimated time believed to allow the market for such investments to recover, projected estimates of
future risk free rates, as well premiums designed to account for liquidity and credit risks associated with its ARS holdings. For its non-transferable right, the Company considered inputs around the issuers credit quality, expected term, and
estimates of future risk free rates. The Companys valuation of both components of its ARS, are contingent upon the financial viability of its investment bank and accordingly, the Company has assigned a credit risk component to both its
valuations based on market data available at the time of valuation. However, if market conditions change and the Companys investment bank is unable to fulfil its commitment, the Company could incur a permanent impairment charge for the
remaining amount of our ARS, which would materially and adversely affect its operating results and overall financial condition. Additionally, the inputs used in the Companys valuation are based on managements estimates at the time of
valuation and require significant judgment. If any of these inputs vary or market conditions change significantly, actual results may differ and the Companys overall financial condition and operating results may be materially and adversely
affected.

Note 3Fair Value of Financial Instruments

The Company measures at fair value certain financial assets and liabilities, including cash equivalents, long-term investments, and its ARS settlement
right. SFAS No. 157 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while
unobservable inputs reflect the Companys market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1Quoted prices for identical instruments in active markets

Level 2Quoted prices for similar
instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are
unobservable.

The following table summarizes the fair value measurements as of December 31, 2008, for the Companys financial
instruments, including its ARS (in thousands):

Although
many of the raw materials used in the Companys internal and outsourced manufacturing operations are available from a number of alternative sources, some of these are obtained from a single supplier or a limited number of suppliers. The Company
and its outsourced manufacturing partners contract with third parties for a continuing supply of the components used in the manufacture of our products. The Company currently relies solely on Intel for the supply of some microprocessors and other
components. Alternative sources of components that are procured from one supplier or a limited number of suppliers would be difficult to locate and/or it would require a significant amount of time and resources to establish and accommodate.

Note 6Long-Lived Assets Held for Sale

Beginning in 2001, RadiSys made it part of its strategic plan to significantly reduce its costs. As part of its plan to reduce costs RadiSys began in 2004 to outsource the manufacture of most of its products. Through various restructuring
activities, facilities requirements for manufacturing and other activities in the Hillsboro, Oregon location have decreased significantly. As a result, management decided to transfer operations currently located in one of the Companys
buildings in Hillsboro, Oregon (DC3 building) to its other building located in Hillsboro, Oregon and its contract manufacturing partners.

In January 2006, RadiSys vacated the DC3 building and put it and the surrounding land, which had previously been held for future expansion, on the market for sale. The assets held for sale had a recorded value of $3.5
million which included land with a value of $2.2 million, building and building improvements with a net value of $1.3 million, and machinery and equipment with a net value of $38,000. The Company classified this facility in net assets held for sale
as of January 31, 2006, and as a result ceased depreciation of these assets.

During 2007, the Company sold the DC3 building and one
of the remaining lots of land held for $3.0 million resulting in a gain of $212,000 included in selling, general and administrative expenses in the Consolidated Statement of Operations. The balance in long-lived assets held for sale as of
December 31, 2008 of $644,000 relates to the remaining parcel of land, and is recorded in other current assets as of December 31, 2008 and 2007.

Note 8Goodwill

Pursuant to SFAS No. 142, the Company is required to test goodwill for impairment at least annually. Additionally, the Company assesses goodwill for
impairment if any adverse conditions exist that would indicate impairment. Conditions that would trigger an impairment assessment, include, but are not limited to, a significant decline in the Companys market capitalization, a significant
adverse change in legal factors or in the business climate that could affect the value of an asset or an adverse action or assessment by a regulator. The Company is considered one reporting unit. As a result, goodwill impairment testing is performed
at the reporting unit level in a two-step process, which consists of, first, comparing the Companys fair value to its carrying value, including goodwill. If the Companys fair value exceeds its carrying value, applicable goodwill is not
considered to be impaired. If the Companys carrying value exceeds its fair value, there is an indication of impairment, upon which time the Company would perform the second step, which includes a further and more detailed analysis in order to
corroborate any such impairment.

In accordance with SFAS No. 142, the Companys annual goodwill impairment test was performed
during the third quarter of 2008. General economic conditions combined with a decline in the Companys stock price, were considered triggering events that required management to re-perform its goodwill impairment test at the end of the fourth
quarter of 2008. To perform the test, a fair value for the Company was estimated primarily based on the market approach, which used the market capitalization method. An impairment loss was then calculated based on an allocation of the fair
value of the Company to the fair value of the Companys assets and liabilities in a manner similar to a purchase price allocation in a business combination. This resulted in an impairment charge representing the entire balance of goodwill,
which totaled $67.3 million, net of adjustments and as of December 31, 2008 the Company had no remaining indefinite lived intangible assets.

The following is a summary of the change in Companys total balance during the year ended December 31, 2008 (in thousands):

Intangible assets amortization expense was $19.0 million, $19.4 million and $6.6 million for the
years ended December 31, 2008, 2007 and 2006, respectively. The Companys purchased intangible assets have lives ranging from one to 10 years. In accordance with SFAS No. 144, the Company reviews for impairment of all its purchased
intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

General economic conditions as well as the decline in the Companys stock price were considered triggering events that required the Company to re-perform an impairment test of its long lived assets, including intangible assets. This
analysis was performed in accordance with SFAS No. 144. For its long lived intangible assets, the Company determined no impairment existed, however, during its analysis, the remaining depreciable lives were reviewed for adequacy. The
Company noted that expected future benefits derived from certain MSBU intangible assets exceeded their remaining depreciable lives. Accordingly, an adjustment was made in order to match amortization expense over the period of expected future
benefit. The intangible asset categories impacted were existing technology and customer lists. The adjustments to depreciable lives of the Companys intangible assets were treated as changes in estimates and, in accordance with Statement of
Financial Accounting Standard No. 154, Accounting Changes and Error Corrections, their effects were recognized prospectively in our Consolidated Financial Statements, effective October 1, 2008.

The intangible asset balance within existing technology is made up of one asset, which is related to technology acquired in the Companys purchase
of Convedia in 2007. In the quarter and year ended December 31, 2008, this prospective treatment resulted in a reduction in our amortization expense of $637,000. The balance within customer lists is also associated with the Convedia
acquisition. In the quarter and year ended December 31, 2008, this prospective treatment resulted in a reduction in our amortization expense of $1.0 million. In the quarter and year ended December 31, 2008, this prospective treatment
resulted in a collective

Note 11Accrued Restructuring and Other Charges

Accrued restructuring is recorded in other accrued liabilities as of December 31, 2008 and 2007, and consisted of the following (in thousands):



|                                         |  |                  |    |                  |   |

The Company evaluates the adequacy of the accrued restructuring charges on a quarterly basis. The
Company records certain reclassifications between categories and reversals to the accrued restructuring charges based on the results of the evaluation. The total accrued restructuring charges for each restructuring event are not affected by
reclassifications. Reversals are recorded in the period in which the Company determines that expected restructuring obligations are less than the amounts accrued.

Fourth Quarter 2006 Restructuring

During the fourth quarter of 2006, the Company initiated a
restructuring plan that included the elimination of 12 positions primarily supporting the Companys contract manufacturing operations as a result of the termination of the relationship with one of the Companys contract manufacturers in
North America. The restructuring plan also includes closing the Charlotte, North Carolina manufacturing support office. The Company expects this office closure to be completed by January 31, 2009.

Second Quarter 2007 Restructuring

During the second quarter of 2007, the Company incurred employee-related expenses associated with skill set changes for approximately 20 employees. The changes involved creating an integrated structure with the media server business along
with some skill set changes in certain selling, general and administrative and engineering groups. The costs incurred in this restructuring event include employee severance and medical benefits, and associated legal costs. All restructuring
activities were completed by March 31, 2008.

Second Quarter 2008 Restructuring

During the second quarter of 2008, the Company initiated a restructuring plan that included the elimination of 23 positions. The restructuring was
primarily initiated with the intent to return the Companys engineering spend to levels which align with targeted profitability as well as refocus the Companys skill sets in new product deployment and provide enhanced service and support
to existing customers. The Company expects to complete all activities associated with the restructuring by March 31, 2009.

The
following table summarizes the changes to the second quarter 2008 restructuring costs (in thousands):

Note 13Short-Term Borrowings

Silicon Valley Bank

On August 7, 2008, the Company entered into a secured revolving line of credit agreement (the Agreement) with Silicon Valley Bank, as the Lender. The Agreement provides the Company with a two-year
secured revolving credit facility of $30.0 million, which is subject to a borrowing base and secured by its accounts receivable. Borrowings under the Agreement will bear interest at the prime rate, which was 3.25% as of December 31, 2008, or
the LIBOR rate, which was 0.44% as of December 31, 2008, plus 1.25%, with either interest rate determined by the Companys election. The Company is required to make interest payments monthly. The Company is further required to pay a
commitment fee equal to 0.08% of the $30.0 million maximum borrowing limit on an annual basis, and to pay quarterly in arrears an unused facility fee in an amount equal to 0.375% per year of the unused amount of the facility. In addition, the
credit facility provides sub-facilities for letters of credit and foreign exchange contracts to be issued on the Companys behalf.

The credit facility requires the Company to make and maintain certain financial covenants, representations, warranties and other agreements that are customary in credit agreements of this type. The Agreement requires the Company to
maintain a minimum current ratio (current assets divided by the sum of current liabilities less deferred income plus the amount of outstanding advances and letters of credit) of 1.5 as of December 31, 2008 and during quarterly periods
thereafter. Additionally, any quarterly EBITDA (earnings before interest, taxes, depreciation, amortization, stock based compensation and goodwill impairment charges, as defined in the Agreement) loss may not exceed $2.5 million in any one quarter,
and quarterly EBITDA may not be negative for any two consecutive quarters for the duration of the Agreement. Further, the Companys EBITDA may not be negative for the year ended December 31, 2008. For quarterly periods beginning after
January 1, 2009, the Company must maintain a positive rolling four quarter EBITDA. In addition, capital expenditures may not exceed $12.0 million in any fiscal year. During the fourth quarter of 2008, the Company amended the Agreement with
Silicon Valley bank. The amendment included a one-time exclusion for the goodwill impairment charge recognized in the fourth quarter of 2008.

Amounts borrowed and repaid are available for re-borrowing during the term of the facility. Outstanding amounts are due in full on the maturity date of August 6, 2010. Upon the occurrence of certain events of default specified in the
Agreement, amounts due under the Agreement may be declared immediately due and payable.

As of December 31, 2008, the Company had no
outstanding balances on the line of credit or letters of credit issued on its behalf.

UBS

During August of 2008, UBS AG, the parent company of the securities firm with which the Company holds its ARS, announced an offer to its clients holding auction rate securities (the Offer). Under the
Offer, UBS AG would issue Auction Rate Securities Rights (the Rights) to the Company. The Rights would allow the Company to sell the ARS held in the Company accounts with UBS Financial Services, Inc. or UBS Securities LLC to UBS AG at
par value during the period beginning June 30, 2010 and ending July 2, 2012. Under the Offer, the Company would also be entitled to receive no net cost loans from UBS AG or its affiliates for up to 75% of the market value of the
Companys ARS.

The Company accepted the Offer and entered into a Credit Line Agreement (the Credit Line), including an
Addendum to Credit Line Account Application and Agreement, with UBS Bank USA and on December 12, 2008 borrowed approximately $39.8 million under the Credit Line. On December 15, 2008, the Company used a portion of the proceeds to pay in
full the outstanding principal balance of approximately $20.0 million under its secured revolving line of credit agreement with Silicon Valley Bank. The amount of interest the Company will pay under the Credit Line is intended to equal the amount of
interest the Company would receive with respect to the Companys auction rate securities and is currently set at T-Bill plus 1.20%, which will be subject market fluctuations. The borrowings under the Credit Line are payable upon demand;
however, UBS Bank USA or its affiliates are required to provide to the Company alternative financing on substantially similar terms, unless the demand right was exercised as a result of certain specified events or the customer relationship between
UBS Bank USA and the Company is terminated for cause by UBS Bank USA. As of December 31, 2008, the Company had an outstanding balance on the Credit Line in the amount of $39.5 million.

Note 14Convertible Debt

2023 Convertible
Senior Notes

During November 2003, the Company completed a private offering of $100 million in aggregate principal amount of the
2023 convertible senior notes due November 15, 2023 to qualified institutional buyers. The discount at issuance on the 2023 convertible senior notes amounted to $3 million.

During the first quarter of 2008, the Company repurchased $52.5 million aggregate principal amount of the 2023 convertible senior notes, with an
associated discount of $1.3 million. The notes were repurchased in the open market for $51.1 million and, as a result, the Company recorded a gain of $68,000.

During the second quarter of 2008, the Company repurchased $10.0 million aggregate principal amount of the 2023 convertible senior notes, with an associated discount of $240,000. The Company repurchased the notes in
the open market for $9.8 million and, as a result, recorded a net loss of $31,000.

On November 15, 2008, the holders of the 2023
convertible senior notes required the Company to purchase, in cash, the entire remaining aggregate amount outstanding, together with accrued and unpaid interest as of this date. As such, the Company repurchased $37.5 million aggregate principal
amount of the 2023 convertible senior notes, with an associated discount of $874,000. The Company repurchased the notes in the open market for $37.5 million and, as a result, recorded a net loss of $874,000. As of December 31, 2008, the 2023
convertible senior notes were fully retired.

2013 Convertible Senior Notes

On February 6, 2008, the Company offered and sold in a public offering pursuant to the shelf registration statement $55.0 million aggregate principal
amount of 2.75% convertible senior notes due 2013 (the 2013 convertible senior notes). Interest on the 2013 convertible senior notes is payable semi-annually, in arrears, on

each August 15 and February 15, beginning on August 15, 2008, to the holders of record at the close of business on the preceding August 1
and February 1, respectively. The 2013 convertible senior notes mature on February 15, 2013. Holders of the 2013 convertible senior notes may convert their notes into a number of shares of the Companys common stock determined as set
forth in the indenture governing the notes at their option on any day to and including the business day prior to the maturity date. The 2013 convertible senior notes are initially convertible into 76.7448 shares of the Companys common stock
per $1,000 principal amount of the notes (which is equivalent to a conversion price of approximately $13.03 per share), subject to adjustment upon the occurrence of certain events. Upon the occurrence of a fundamental change, holders of the 2013
convertible senior notes may require the Company to repurchase some or all of their notes for cash at a price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest, if any. In addition, if certain
fundamental changes occur, the Company may be required in certain circumstances to increase the conversion rate for any 2013 convertible senior notes converted in connection with such fundamental changes by a specified number of shares of the
Companys common stock. The 2013 convertible senior notes are the Companys general unsecured obligations and rank equal in right of payment to all of its existing and future senior indebtedness, and senior in right of payment to the
Companys future subordinated debt. The Companys obligations under the 2013 convertible senior notes are not guaranteed by, and are effectively subordinated in right of payment to all existing and future obligations of its subsidiaries
and are effectively subordinated in right of payment to its future secured indebtedness to the extent of the assets securing such debt.

In
connection with the issuance of the 2013 convertible senior notes, the Company entered into a capped call transaction with a hedge counterparty. The capped call transaction is expected to reduce the potential dilution upon conversion of the 2013
convertible senior notes in the event that the market value per share of the Companys common stock, as measured under the terms of the capped call transaction, at the time of exercise is greater than the strike price of the capped call
transaction of approximately $13.03, which corresponds to the initial conversion price of the 2013 convertible senior notes and is subject to certain adjustments similar to those contained in the notes. If, however, the market value per share of the
Companys common stock exceeds the cap price of the capped call transaction of $23.085, as measured under the terms of the capped call transaction, the dilution mitigation under the capped call transaction will be limited, which means that
there would be dilution to the extent that the then market value per share of the Companys common stock exceeds the cap price of the capped call transaction.

During the fourth quarter of 2008, the Company repurchased $5.0 million aggregate principal amount of the 2023 convertible senior notes, with associated unamortized issuance costs of $196,000. The Company repurchased
the notes in the open market for $3.1 million and, as a result, recorded a net gain of $1.7 million.

As of December 31, 2008, the
Company had outstanding 2013 convertible senior notes with a face value and fair value of $50.0 million and $26.9 million, respectively.

Convertible Subordinated Notes

During August 2000, the Company completed a private offering of $120 million in
aggregate principal amount of 5.5% convertible subordinated notes due to qualified institutional buyers. The discount at issuance on the convertible subordinated notes amounted to $3.6 million. The remaining outstanding notes of $2.4 million were
paid at maturity on August 15, 2007.

Note 15Hedging

The Companys activities expose it to a variety of market risks, including the effects of changes in foreign currency exchange rates. During the first quarter of 2008, the Company entered into forward exchange
contracts, designated as foreign-currency cash flow hedges, to reduce the potentially adverse effects of foreign currency

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



exchange rate fluctuations that occur in the normal course of business. All hedging transactions are conducted with a large, and in the opinion of
management, reputable and financially stable financial institution.

These derivatives are recognized on the balance sheet at their fair
value. Unrealized gain positions are recorded as other current assets and unrealized loss positions are recorded as other current liabilities as all maturity dates are less than one year. Changes in the fair values of the outstanding derivatives
that are highly effective are recorded in other comprehensive income until net income is affected by the variability of the cash flows of the hedged transaction. Changes in the fair values of the derivatives not effective as hedging instruments are
recognized in earnings in the current period. Results of hedges are recorded in the expense line item being hedged, which is primarily R&D, when the underlying hedged transaction affects net income (loss).

The Company evaluates, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions have
been highly effective in offsetting changes in the cash flows of hedged items and whether those derivatives are expected to remain highly effective in future periods.

For the year ended December 31, 2008, the Company had a net foreign exchange hedge-related transaction loss of $190,000. As of December 31, 2008, the Company had forward contracts outstanding in the amount
of $5.7 million that mature monthly over the next eleven months. For the year ended December 31, 2008, the Company had recorded as other comprehensive income, unrealized losses of $859,000 on outstanding derivatives. The majority of these
amounts are expected to be reclassified from other comprehensive (loss) income to other (expense) income within the next twelve months. As of December 31, 2008, the Company had no ineffective hedges because forward foreign currency contract
amounts were less than the specifically identified anticipated transactions being hedged.

Note 16Commitments and Contingencies

RadiSys leases most of its facilities, certain office equipment, and vehicles under non-cancelable operating leases which require minimum lease payments
expiring from one to four years after December 31, 2008. Amounts of future minimum lease commitments in each of the five years ending December 31, 2009 through 2013 and thereafter, are as follows (in thousands):

Rent expense totaled $5.4 million, $5.7 million and $3.6 million for the years ended

Adverse Purchase Commitments

The Company is contractually obligated to reimburse its contract manufacturers for the cost of excess inventory used in the manufacture of the
Companys products, if there is no alternative use. This liability, referred to as adverse purchase commitments, is provided for in other accrued liabilities in the accompanying balance sheets. Estimates for adverse purchase commitments are
derived from reports received on a quarterly

basis from the Companys contract manufacturers. Increases to this liability are charged to cost of goods sold. When and if the Company takes possession
of inventory reserved for in this liability, the liability is transferred from other accrued liabilities (Note 12Other Accrued Liabilities) to the excess and obsolete inventory valuation allowance (Note 5Inventories).

Guarantees and Indemnification Obligations

As permitted under Oregon law, the Company has agreements whereby it indemnifies its officers, directors and certain finance employees for certain events or occurrences while the officer, director or employee is or
was serving in such capacity at the request of the Company. The term of the indemnification period is for the officers, directors or employees lifetime. The maximum potential amount of future payments the Company could be required
to make under these indemnification agreements is unlimited; however, the Company has a Director and Officer insurance policy that limits its exposure and enables the Company to recover a portion of any future amounts paid. To date, the Company has
not incurred any costs associated with these indemnification agreements and, as a result, management believes the estimated fair value of these indemnification agreements is minimal. Accordingly, the Company has not recorded any liabilities for
these agreements as of December 31, 2008.

The Company enters into standard indemnification agreements in its ordinary course of
business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Companys business partners or customers, in
connection with patent, copyright or other intellectual property infringement claims by any third party with respect to the Companys current products, as well as claims relating to property damage or personal injury resulting from the
performance of services by us or the Companys subcontractors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is generally limited. Historically, the Companys
costs to defend lawsuits or settle claims relating to such indemnity agreements have been minimal and accordingly management believes the estimated fair value of these agreements is immaterial.

The Company provides for the estimated cost of product warranties at the time it recognizes revenue. Products are generally sold with warranty coverage
for a period of 24 months after shipment. Parts and labor are covered under the terms of the warranty agreement. The workmanship of the Companys products produced by contract manufacturers is covered under warranties provided by the contract
manufacturer for a specified period of time ranging from 12 to 15 months. The warranty provision is based on historical experience by product family. The Company engages in extensive product quality programs and processes, including actively
monitoring and evaluating the quality of its components suppliers; however ongoing failure rates, material usage and service delivery costs incurred in correcting product failure, as well as specific product class failures out of the Companys
baseline experience affect the estimated warranty obligation. If actual product failure rates, material usage or service delivery costs differ from estimates, revisions to the estimated warranty liability would be required.

At December 31, 2008, our unrecognized tax benefits associated with uncertain tax positions
were $1.8 million, substantially all of which, if recognized, would favorably affect the effective tax rate.

The Companys ongoing
practice is to recognize potential accrued interest and penalties related to unrecognized tax benefits within its global operations in income tax expense. During the year ended December 31, 2008, potential interest and penalties associated with
uncertain tax positions totaled $678,000, which represents an increase of $51,000 from the balance as of December 31, 2007.

The Company and its subsidiaries are subject to federal income tax as well as income tax of
multiple state and foreign jurisdictions. The Companys statute of limitations is closed for all federal and state income tax years before 2005 and 2004, respectively. The statute of limitations for the Companys Canadian subsidiary is
closed for all tax years ended before October 31, 2005. The statute of limitations for the Companys other foreign subsidiaries is closed for all income tax years before 2002 which includes federal and state income tax returns. However, to
the extent allowed by law, the taxing authorities may have the right to examine prior periods where net operating losses and credits were generated and carried forward, and make adjustments up to the net operating loss and credit carryforward
amounts.

The Company is not currently under Internal Revenue Service (IRS) examination. During 2005, the Company settled an IRS tax
examination related to the 1996 through 2002 tax years. In the fourth quarter of 2006, the German tax authorities commenced audits of 2002 through 2004 years. The German taxing authority has completed their examination and all audit adjustments were
essentially settled during the third quarter of 2008. The final audit adjustments did not have a material impact on the Companys position or results of operations. In the fourth quarter of 2008, the Canada Revenue Agency commenced routine tax
inquiries for the taxation years 2005 through 2007. The Company is not currently under examination in any other states or foreign jurisdictions.

During the year ended December 31, 2008, the Company recorded a reduction to goodwill of $388,000 primarily related to a purchase accounting adjustment to increase a deferred tax asset for acquired net operating losses related to the
acquisition of Microware and the recognition of an acquisition related uncertain tax position.

The Company has recorded valuation
allowances of $5.6 million and $6.3 million at December 31, 2008 and December 31, 2007, respectively, due to uncertainty involving utilization of certain net operating loss and tax credit carryforwards prior to the expiration which will
occur between 2009 and 2026. The decrease in valuation allowance of $752,000 for the year ended December 31, 2008 compared to the year ended December 31, 2007, is primarily attributable to an increase in the utilization of net operating
loss carryforwards from the acquisition of Microware in August 2001 and the expiration of a capital loss carryforward, that was previously reserved.

At December 31, 2008 and 2007, the Company had total available federal net operating loss
carryforwards of approximately $27.9 million and $32.0 million, respectively, before valuation allowance. The federal net operating loss carryforwards expire between 2009 and 2023 and consist of approximately $14.5 million of consolidated taxable
loss remaining after loss carrybacks to prior years, $3.9 million of loss carryforwards from the Texas Micro merger in 1999, and $9.5 million of loss carryforwards from the Microware acquisition in August of 2001. The net operating losses from Texas
Micro and Microware are stated net of limitations pursuant to Section 382 of the Internal Revenue Code. The annual utilization limitations are $5.7 million and $732,000 for Texas Micro and Microware, respectively. The Company had total state
net operating loss carryforwards of approximately $40.2 million and $40.9 million at December 31, 2008 and 2007, respectively, before valuation allowance. The state net operating loss carryforwards expire between 2010 and 2023. The Company also
had net operating loss carryforwards of approximately $5.9 million from certain non-U.S. jurisdictions. The non-U.S. net operating loss carryforwards are primarily attributable to Canada and the U.K. The Canada tax losses are attributable to the
Convedia acquisition in September of 2006 and they expire between 2009 and 2026. The U.K. tax losses may be carried forward indefinitely provided certain requirements are met.

The Company has federal and state research and development tax credit and other federal tax credit carryforwards of approximately $13.3 million at
December 31, 2008, to reduce future income tax liabilities. The federal and state tax credits expire between 2014 and 2028. The federal tax credit carryforwards include research and development tax credits of $1.5 million and $268,000 from the
Texas Micro and Microware acquisitions, respectively. The utilization of these acquired credits is subject to an annual limitation pursuant to Section 383 of the Internal Revenue Code. On October 3, 2008, the Emergency Economic
Stabilization Act of 2008 was signed into law which extended the research and development tax credit through December 31, 2009. Congress has reinstated the tax credit retroactive to January 1, 2008. The Companys Canadian subsidiary
also had approximately $3.6 million in investment tax credit, $8.9 million in unclaimed scientific research and experimental expenditures and $12.5 million in undepreciated capital cost to be carried forward and applied against future income in
Canada.

Realization of the deferred tax assets is dependent on generating sufficient taxable income prior to the expiration of the net
operating loss and tax credit carryforwards. Although realization is not assured, management believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the balance of the
deferred tax assets, net of the valuation allowance, as of December 31, 2008. The amount of the net deferred tax assets that is considered realizable, however, could be reduced in the near term if estimates of future taxable income during the
carryforward periods are reduced. Should management determine that the Company would not be able to realize all or part of the net deferred tax assets in the future, adjustments to the valuation allowance for deferred tax assets may be required.
Pre-tax book loss in fiscal 2008 is primarily the result of the $67.3 million charge associated with the full impairment of our goodwill balances. Of this total charge, approximately $34.0 million is related to stock acquisitions and therefore
not tax deductible for income tax purposes. The pre-tax book losses from foreign operations for fiscal years 2008, 2007 and 2006 are primarily the result of purchased intangible asset amortization and an in-process R&D charge related to the
Convedia Corporation acquisition of $13.7 million, $16.5 million and $19.9 million, respectively. These other acquisition related charges, as well as approximately $34.0 million of the goodwill charge, are not tax deductible and therefore have
not affected taxable income for these years.

Pretax book income (loss) from domestic operations for the fiscal years 2008, 2007 and 2006
was $(42.4) million, $(7.4) million, and $2.4 million, respectively. Pretax book income (loss) from foreign operations for fiscal years 2008, 2007 and 2006 was $(33.1) million, $(16.1) million, and $(16.2) million, respectively. The Company has
indefinitely reinvested approximately $13.3 million of the undistributed earnings of certain foreign subsidiaries at December 31, 2008. Such earnings would be subject to U.S. taxation if repatriated to the United States.

RADISYS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Note 19Employee Benefit Plans

Stock-Based Employee Benefit Plans

Equity instruments are granted to employees, directors and consultants in certain instances, as defined in the respective plan agreements. Beginning in the second quarter of 2005, the Company issued equity instruments in the form of stock
options, restricted shares and shares issued to employees as a result of the employee stock purchase plan (ESPP). Beginning in the third quarter of 2006, the Company began issuing restricted stock units in conjunction with the other
equity instruments. Prior to the second quarter of 2005, the Company issued equity instruments in the form of stock options and ESPP shares, only.

Stock Options and Restricted Stock Awards

On May 15, 2007, the Shareholders approved the 2007 Stock Plan (the
Plan) to replace the 1995 Stock Incentive Plan, the 2001 Nonqualified Stock Option Plan and the RadiSys Corporation Stock Plan for Convedia Employees. The Plan provides the Board of Directors broad discretion in creating employee equity
incentives. Unless otherwise stipulated in the plan document, the Board of Directors, at their discretion, determines stock option exercise prices, which may not be less than the fair market value of RadiSys common stock at the date of grant,
vesting periods and the expiration periods which are a maximum of 10 years from the date of grant. Under the Plan, 3.2 million shares of common stock have been reserved and authorized for issuance to any non-employee directors and employees,
with a maximum of 400,000 shares in any calendar year to one participant. The Plan provides for the issuance of stock options, restricted shares, restricted stock units and performance-based awards.

On May 15, 2008, the shareholders approved the Long-Term Incentive Plan (the LTIP). The LTIP provides for the grants of awards payable
in shares of common stock or cash upon the achievement of performance goals set by the Companys Compensation and Development Committee. The number of shares of the Companys common stock initially reserved for issuance under the LTIP is
2.0 million shares with a maximum of 500,000 shares in any calendar year to one participant.

The table below summarizes the
activities related to the Companys stock plans (in thousands, except weighted average exercise prices):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)





|(A) | The 2007 plan that replaced the 1995 Stock Incentive Plan, the 2001 Nonqualified Stock Option Plan and the RadiSys Corporation Stock Plan for Convedia Employees requires all
restricted stock to be counted as two shares and stock options to be counted as one share.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The aggregate intrinsic value in
the table above represents the total pretax intrinsic value (the difference between the closing price of RadiSys shares as quoted on the NASDAQ Global Select Market for December 31, 2008 and the exercise price, multiplied by the number of
in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2008. The intrinsic value of options changes based on the fair market value of RadiSys stock. Total
intrinsic value of options exercised for the years ended December 31, 2008, 2007 and 2006 was $591,000, $227,000, and $6.4 million, respectively.

The following table summarizes the information about stock options outstanding at December 31, 2008 (shares in thousands):

Employee Stock Purchase Plan

In December 1995, the Company established an Employee Stock Purchase Plan (ESPP). All employees of RadiSys and its subsidiaries who
customarily work 20 or more hours per week, including all officers, are eligible to participate in the ESPP. Separate offerings of common stock to eligible employees under the ESPP (an Offering) commence on
February 15, May 15, August 15 and November 15 of each calendar year (Enrollment Dates) and continue for a period of 18 months. Multiple separate Offerings are in operation under the ESPP at any given time.
An employee may participate in only one Offering at a time and may purchase shares only through payroll deductions permitted under the provisions stipulated by the ESPP. The purchase price is the lesser of 85% of the fair market value of the common
stock on date of grant or that of the purchase date (look-back feature). Pursuant to the provisions of the ESPP, as amended, the Company is authorized to issue up to 5.2 million shares of common stock under the plan. For the years
ended December 31, 2008, 2007 and 2006 the Company issued 596,000, 405,000 and 278,000 shares under the plan, respectively. At December 31, 2008, 1.3 million shares were available for issuance under the plan.

Stock-Based Compensation associated with Stock-Based Employee Benefit Plans

In 2004, in an effort to reduce the amount of stock-based compensation expense that the Company would include in its financial statements after the
effective date of SFAS 123R or January 1, 2006, the Compensation Committee of the Board of Directors approved an acceleration of vesting of those non-director employee stock

options with an option price greater than $15.99, which was greater than the fair market value of the shares on

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



that date ($14.23). Approximately 1.1 million options with varying remaining vesting schedules were subject to the acceleration and became immediately
exercisable. Historically the Company has not accelerated the vesting of employee stock options. As a result of the acceleration, the Company estimates that stock-based compensation expense, net of related tax effects, was reduced by approximately
$1.8 million and $219,000 for the years ended December 31, 2006 and 2007, respectively.

The Company uses the Black-Scholes model to
measure the grant date fair value of stock options and ESPP shares. The grant date fair value of stock options that are expected to vest is recognized on a straight-line basis over the requisite service period, which is equal to the option vesting
period which is, generally, 3 years. The grant date fair value of ESPP shares that are expected to vest is recognized on a straight-line basis over the requisite service period, which is generally, 18 months, subject to modification at the date of
purchase due to the ESPP look-back feature. The Company computes the grant date fair value of restricted stock granted as the closing price of RadiSys shares as quoted on the NASDAQ Global Select Market on the earlier of the date of grant or the
first date of the service period. The grant date fair value of restricted stock that are expected to vest is recognized on a straight-line basis over the requisite service period, which is 3 years. The estimate of the number of options, ESPP shares
and restricted stock expected to vest is determined based on historical experience.

To determine the fair value of the stock options and
ESPP shares using the Black-Scholes option pricing model, the calculation takes into consideration the effect of the following:



| |  |  | Exercise price of the option or purchase price of the ESPP share;
| | - |  | -----------------------------------------------------------------



| |  |  | Price of the Companys common stock on the date of grant;
| | - |  | ---------------------------------------------------------



| |  |  | Expected term of the option or share;
| | - |  | -------------------------------------



| |  |  | Expected volatility of the Companys common stock over the expected term of the option or share; and
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | Risk free interest rate during the expected term of the option or share.
| | - |  | ------------------------------------------------------------------------

The calculation includes several assumptions that require managements judgment. The expected term of the option or share is determined based on
assumptions about patterns of employee exercises, and represents a probability-weighted-average time period from grant until exercise of stock options, subject to information available at time of grant. Determining expected volatility generally
begins with calculating historical volatility for a similar long-term period and then considering the ways in which the future is reasonably expected to differ from the past.

The Company uses three employee populations. The expected term computation is based on historical vested option exercise and post-vest forfeiture
patterns and included an estimate of the expected term for options that were fully vested and outstanding, for each of the three populations identified. The estimate of the expected term for options that were fully vested and outstanding was
determined as the midpoint of a range of estimated expected terms determined as follows: the low end of the range assumes the fully vested and outstanding options settle on the evaluation date and the high end of the range assumes that these options
expire upon contractual term. The risk free interest rate is based on the U.S. Treasury constant maturities in effect at the time of grant for the expected term of the option or share.

401(k) Savings Plan

The Company established a 401(k) Savings Plan (401(k) Plan),
a defined contribution plan, as of January 1, 1989 and amended through January 1, 2007, in compliance with Section 401(k) and other related sections of the Internal Revenue Code and corresponding Regulations issued by the Department
of Treasury and Section 404(c) of Employee Retirement Income Security Act of 1974 (ERISA), to provide retirement benefits for its U.S employees. Under the provisions of the plan, eligible employees are allowed pre-tax contributions
of up to 30% of their annual compensation or the maximum amount permitted by the applicable statutes. Additionally, eligible employees can elect to make catch-up contributions, within the limits set forth by pre-tax contributions, or to the maximum
amount permitted by the applicable statutes. Pursuant to the provisions of the 401(k) Plan, the Company may contribute 50% of pre-tax contributions made by eligible employees, adjusted for loans and withdrawals, up to 6% of annual compensation for
each eligible employee. The Company may elect to make supplemental contributions as periodically determined by the Board of Directors at their discretion. The contributions made by the Company on behalf of eligible employees become 100% vested after
three years of service, or 33% per year after one year of service. The Companys total contributions to the 401(k) Plan amounted to $1.0 million, $905,000 and $887,000 in 2008, 2007 and 2006, respectively. In addition, some of the
Companys employees outside the U.S are covered by various defined contribution plans, in compliance with the statutes of respective countries. The participants pay for the 401(k) Savings Plan administrative expenses.

Deferred Compensation Plan

Effective January 1, 2001, the Company established a Deferred Compensation Plan, providing its directors and certain eligible employees with opportunities to defer a portion of their compensation as defined by the provisions of the
plan. The Company credits additional amounts to the deferred compensation plan to make up for reductions of Company contributions under the 401(k) Plan. The deferred amounts are credited with earnings and losses under investment options chosen by
the participants. The Company sets aside deferred amounts, which are then invested in long-term insurance contracts. All deferred amounts and earnings are 100% vested at all times, but are subject to the claims of creditors of the Company under a
bankruptcy proceeding. Benefits are payable to a participant upon retirement, death, and termination of employment and paid as elected by the participant in accordance with the terms of the plan. The Plan also permits scheduled in-service
distributions. (see Note 10- Other Assets) Deferred amounts may be withdrawn by the participant in case of financial hardship as defined in the plan agreement.

Note 20Segment Information

The Company has adopted SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information. SFAS No. 131 establishes standards for the reporting by public business enterprises of information about operating segments, products and services, geographic areas, and major customers. The method for
determining what information to report is based upon the way that management organizes the segments within

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

Executive Compensation Discussion and Analysis (CD&A)

Section I: Introduction

This narrative describes the philosophy, approach and elements used by us and the Compensation and Development Committee of our Board of Directors to
define, manage and review compensation paid to our executives. The philosophy and management approach for executive compensation described below applies to all executives including those executives designated as named executive officers.

Our Compensation and Development Committee is responsible for the design and management of our executive compensation programs as well as the
philosophy and programs for all employee compensation, benefit, and development programs on a worldwide basis. The Committee operates under a written charter, which is formally reviewed annually by the members of the Committee and is revised as
needed. Our Board of Directors regularly reviews the Committee charter and any changes the Committee makes to it. The charter is available on our website at www.radisys.com under the investor relations tab.

Our Compensation and Development Committee regularly reviews and uses data, analysis and recommendations from internal staff and survey data from
Radford, a division of Aon Corporation, an independent executive compensation survey and consulting firm to establish the approach and implementation of executive compensation. The Committee maintains an annual calendar to guide the timing of its
review, analysis, and decision making related to compensation, benefits, and development programs. Our Chief Executive Officer, Chief Financial Officer, and Human Resources staff provide management inputs and recommendations to the Committee on
matters of executive compensation.

Our Board of Directors has delegated responsibility to the Compensation and Development Committee for
final approval of decisions related to all executive employment offers, adjustments to base salary and bonus targets, equity grants, payments for executive incentive bonuses, as well as any executive change of control agreements, succession plans,
and other programs which are related to the executives. Under the supervision of the Committee, our Chief Executive Officer, Chief Financial Officer and Human Resources staff have responsibility for the implementation of our executive compensation
programs. The Committee also guides executive development programs and succession planning in order to maintain and develop the Companys leadership and management capability.

Section II: Philosophy and Objectives of Executive Compensation Programs

The Compensation and
Development Committee has adopted a philosophy of executive compensation that is based on performance and is competitive with other similar sized high tech companies. The goal of our compensation program is to attract and retain the executives and
employees needed to achieve our business objectives, and to substantially link executive compensation with near-term performance on operating plans and longer-term strategic progress. Our executive compensation program is comprised of cash
compensation (base salary and incentive bonus), equity incentive grants, employee benefits, a deferred compensation program, paid time off and a 401(k) matching plan.

Annually, our Compensation and Development Committee, with the assistance of the Chief Executive Officer, the Chief Financial Officer, and the Human Resources staff reviews base salaries, incentive bonus targets and
equity compensation paid in the market by the peer group of companies identified in the Radford Total Compensation Survey U.S. Executive report, which included summary data from 111 U.S. based high tech companies with annual revenues between $200
 499 million (average revenue is approximately $331 million). This information is used to assure our base salaries, incentive bonus targets and equity grants are competitive with other companies in the same industry and revenue size. The
Committee believes that using third party peer group benchmark data is essential to determining market competitive compensation to ensure the attraction and



101



---

##### Table of Contents

retention of key management. To ensure accurate data collection based on actual job duties, our executive positions are individually benchmarked with the
Radford Survey data using a detailed review of the job responsibilities and scope for each executive role as defined by their job descriptions.

Our Compensation and Development Committee has historically considered salary, bonus and equity compensation as a package in making annual compensation decisions and uses tally sheets to consider and evaluate the total potential
compensation of executives from all sources upon various scenarios and any benefits associated with voluntary and involuntary termination of employment.

Section III: Design of Our Compensation Programs, Individual Elements, and Impact of Performance on Compensation

The design
of our executive compensation program includes three main categories:



| | 1. | Cash compensation, which includes base salary, incentive bonus plan (target and actual) and other potential incentive cash awards.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------



| | 2. | Equity incentive awards, which may include stock option grants, restricted stock grants, or a combination thereof.
| | -- | ------------------------------------------------------------------------------------------------------------------



| | 3. | Employee benefits, including health care insurance, employee stock purchase program under the RadiSys Corporation 1996 Employee Stock Purchase Plan (ESPP), 401(k) plan,
flexible spending accounts, life insurance, and other benefits. Employee benefit programs are the same for all U.S. employees including executive officers. Executive officers receive no special employee benefits except that U.S. employees at
director level and above are eligible to participate in our Non-Qualified Deferred Compensation Plan. By approval of our Compensation and Development Committee, change of control agreements and severance agreements are used in selected situations as
described in the section outlining potential post-employment payments.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Total Cash Compensation. The total cash compensation for an executive is the sum of the base salary amount plus the cash incentive bonus amount. Our goal is for an executives targeted total cash compensation to be approximately
equal to the 50thpercentile of the Radford median market data when shared and individual objectives are met. At the end of 2008, the total cash
compensation for our Chief Executive Officer at 100% cash incentive bonus payout was at the 35thpercentile of Radford market data and our Chief
Financial Officer was at the 37thpercentile. The average total cash compensation among the rest of the named executive officers at 100% cash
incentive bonus payout was at the 58thpercentile of Radford market data.

Base Salary. Our objective is that the base salaries of our executives be between the 25thand 50thpercentile (median) of the market
data. At the end of 2008, the base salary was at the 39thpercentile of Radford market data for our Chief Executive Officer and the 39thpercentile for our Chief Financial Officer. The base salary for the rest of the named executive officers was at the 43rdpercentile of the Radford market data. This approach is based on the principle that a competitive base salary is required to attract and retain the qualified and experienced
executive talent required to effectively lead and manage our business, while placing more upside in incentive bonus targets.

Our
Compensation and Development Committee reviews base salary for each executive on an annual basis as part of the company-wide merit review process. The amount of any merit increase to an executives base salary is determined based on a
combination of the current position of the executives pay against market data and the executives performance and results during the past year. Our Chief Executive Officer is responsible for assessing the performance of each executive
reporting to him. The Committee assesses the performance of our Chief Executive Officer annually. The Chief Executive Officer performance review process includes a Chief Executive Officer self appraisal, a formal Board of Directors evaluation
process as well as a written performance appraisal delivered by the Chairman of the Board of Directors. In addition the Committee reviews the overall performance assessment of his direct reports, including all named executive officers.

##### Table of Contents

An executives base salary is increased if warranted based on the executives performance and
business results provided the resulting base salary remains within the targeted zone of the market data. By exception, our Compensation and Development Committee or Chief Executive Officer may determine that an individual executives base
salary should be above (or below) the targeted zone due to extenuating factors. In this case the executives compensation may be outside the targeted zone. In 2008, our executive and broad employee base salaries increased an average of 3% based
on performance and market data. Due to the uncertain economic climate, on January 27, 2009, the Board of Directors decided to forego any Board and Executive merit increases for 2009.

Cash Incentive Bonus. Based on Radford survey data, job level, and our compensation program
philosophy, each executive is assigned an annual cash incentive bonus amount. The executive cash incentive bonus is designed to be a significant portion of executive compensation in order to create high incentive for our executives to perform
against annual and strategic objectives. The cash incentive bonus when paid at 100% of plan is targeted to be at the 50thto 75thpercentile of the Radford market data. By setting the potential (target) incentive bonus to be between the 50thto 75thpercentile, our Compensation and Development Committee believes that we
are encouraging our executives to achieve higher levels of performance. At the end of 2008, the cash incentive bonus at 100% payout was at the 31stpercentile of Radford market data for our Chief Executive Officer and at the 33rdpercentile for our Chief Financial Officer. The cash incentive
bonus at 100% payout for the rest of the named executive officers was at the 63rdpercentile of the Radford market data.

In addition, there is a difference between targeted bonus and actual paid bonus. Actual bonus payments are funded by profitability against our target
model and paid out based on the performance by each executive to defined objectives. For the five years leading up to 2008, actual total cash compensation funded for all executives has been below targeted compensation as we continued to invest in
new strategies which impacted profitability and therefore the level of bonuses funded. This curtailed funding of bonuses would have further reduced the performance to Radford benchmarks referenced above.

Our incentive bonus target is expressed as a dollar amount and the incentive bonus pool for executives as well as all employees is funded based on
certain levels of non-GAAP operating income. Operating income goals and resulting bonus pool funding levels are established at the beginning of each year through our annual operating plan process. Actual operating income results determine the
available bonus pool. This incentive bonus pool is calculated by our Finance department with review and approval by our Compensation and Development Committee on a semi-annual basis along with any actual payouts to each executive, including our
Chief Executive Officer. Our Chief Financial Officer calculates the proposed bonus payout amounts based on the bonus pool, performance results, and the individual executives bonus target. If we underachieve or over-achieve our objectives for
operating income, the bonus pool is adjusted accordingly. In addition, minimum levels of non-GAAP operating income must be met before there is any payout. Further lower achievement of individual annual and strategic objectives would also reduce the
payout. Funding levels for the bonus pool have been 162%, 50%, and 67% for 2008, 2007 and 2006, respectively. The incentive bonuses of other executives are designed and managed using the same performance based program as our named executive
officers.

The Compensation and Development Committee establishes the maximum payout which could be made on an annual basis at the
beginning of the year. For example, the maximum payout which could have been made in 2008 was two times the targeted amount. The Committee also has discretion to make adjustments to individual bonus payouts to executives and the broad employee base
when in its business judgment, it believes that the results obtained by the formula may not provide the appropriate judgment of performance. In 2008, the Committee used its discretion to increase the earned payouts to certain named executive
officers by a total of $135,000.

Our other employees also participate in a bonus program with targeted annual bonus amounts based on the
level of their position in the organization and for performance to established objectives in the case of non-executive management. The incentive bonuses of all other company non-executive management are



103



---

##### Table of Contents

designed and managed using a performance based program similar to our executives, as described below. For the year 2008, the bonus pool payout for all
eligible employees was approximately 162% of the annual target amount. This is the same percentage bonus pool paid for executives, including our Chief Executive Officer.

The calculation of an individual executives bonus is based on the calculated bonus pool times performance against shared/corporate objectives (weighted 50%) and performance against department/individual
objectives (weighted 50%). The Committee believes that assigning equal weights to the shared/corporate objectives and department/individual objectives provides an appropriate balance of rewarding and encouraging overall performance to promote
teamwork with recognizing and rewarding individual/department performance.

Our shared/corporate objectives are developed by our Chief
Executive Officer and reviewed by our Board of Directors. The shared/corporate objectives and progress towards these objectives are periodically reviewed by our Board of Directors and Compensation and Development Committee during the year. For 2008,
these shared objectives related to enhancements to customer service, the successful integration of the Intel Modular Communications Platform ATCA business we acquired in the fourth quarter of 2007, a ramp-up of revenues on new products, and targeted
market share growth. On average, the shared/corporate objectives were 96% achieved based on the annual operating plan.

Individual
objectives for each executive officer are developed by the Chief Executive Officer with the executive and then reviewed by the Compensation and Development Committee. The individual performance objectives include both quantitative and subjective
metrics, such as quality, service, new product introduction, sales, design wins, working capital and cost improvements, and strategy realization, depending on the job function of the executive. Individual executive bonus amounts paid out vary
depending on the individual results against these objectives. For 2008, the Committee determined that the individual performance objectives were 115%, 93%, 86%, 96% and 97% achieved by Mr. Bronson, Mr. Lepiane, Ms. Harper,
Mr. Ambrose and Mr. Grout, respectively. The Committee reviews and approves our Chief Executive Officers quantitative assessment of executive performance and the proposed executive bonus amounts to be paid to each executive with such
qualitative modifications as the Committee may make at its discretion. The Committee assesses performance of our Chief Executive Officer and determines the amount of bonus to be paid to our Chief Executive Officer based on the same calculation used
for other executives.

In addition to our cash-based, pay-for-performance incentive compensation plan described above, we maintain a
cash-based reward program for selected members of our sales and marketing departments who can most directly impact revenues of our media server business (MSBU Plan). The named executive officer participants in the MSBU Plan include
Messrs. Ambrose and Lepiane. Payouts under the MSBU Plan are determined based on the achievement of the pre-determined revenue objectives of our media server business unit. The objectives for the MSBU Plan are proposed by our Chief Executive Officer
and reviewed, modified and approved by our Compensation and Development Committee. Depending on the actual results, as determined by the Committee, final payouts may be below (but not above) the targeted amount payable at 100% of the
objectives achievement. The MSBU Plan payout pool is calculated by our Finance department with review and approval by our Chief Executive Officer and the Committee.

Equity Incentive Awards. We believe that long-term incentives in the form of stock options, restricted stock, or other equity instruments are a highly effective way to link the interests of management and
shareholders, and to motivate management to drive longer term shareholder value. Stock option and/or restricted stock grants are made to executives under the RadiSys Corporation 2007 Stock Plan. For 2008, the annual equity grant made to each
executive consisted of stock options and restricted stock units. For 2009, the annual equity grant made to each executive consisted solely of stock options. The decision to grant only stock options was due to the Companys stock price and the
ongoing effort to reduce overall burnrate.

Our Compensation and Development Committee uses Radford survey data as a reference point in
determining the amounts and allocation of equity grants by executive position. Radford survey data on equity grants to executives at similar sized high tech companies is reviewed and analyzed annually. The Committees



104



---

##### Table of Contents

objective is to provide equity grants to executives that are at approximately the 50thto 75thpercentile of market data for the Radford Survey peer group companies. In addition, the retentive value of
past grants for each executive is reviewed to ensure that the value of unvested equity grants is in line with benchmarks and is of sufficient value to assure retention and strong performance incentive for the executive in future years.

All equity grants to newly hired executives and annual (refresher) grants to existing executives are reviewed and approved by our
Compensation and Development Committee using the above mentioned factors of market data, the total retention value, and the executives projected level of future contribution. Grants of equity awards are made at predetermined times and are not
intentionally scheduled to coincide with the disclosure of favorable or unfavorable information. Each year we review to determine whether refresher grants are necessary to continue to motivate management and employees while providing long term
incentives.

Our Compensation and Development Committee anticipated implementing a new, performance-based Long-Term Incentive Plan
(LTIP) in 2008, following its approval by shareholders in May 2008. The LTIP is intended to create an incentive for exceptional performance in addition to our annual refresher stock program that enables us to attract, retain and motivate
senior executives and other key employees. The difference between the annual refresher stock program and LTIP is that the LTIP grants are performance based and participants are only eligible to receive these awards if certain financial or strategic
metrics, such as non-GAAP earnings per share (EPS), meet or exceed threshold targets established by our Compensation and Development Committee. These targets will be stretch goals above the targets in our operating plan and require
superior corporate performance to be earned.

The LTIP awards, when combined with annual refresher stock grants made to executives, are
designed to strongly align equity grants with higher levels of company performance. Because of the dramatic change in the global economic environment, it became difficult to establish longer-range corporate performance targets at the end of 2008 and
our Compensation and Development Committee decided to delay the start of the LTIP program. We anticipate that the program will be initiated in the second half of 2009.

Finally, our executive officers are expected to acquire and hold a minimum number of shares equal to one year of their annual base salary. The minimum amount is expected to be reached within three to five years from
joining us or being promoted to an executive role. Of our five current named executive officers, four have already reached this ownership goal, including our Chief Executive Officer who is over three times the stock ownership goal.

Executive and Employee Benefits. RadiSys provides employee benefit programs to executive
officers which are the same as those benefits provided to other employees in the same country. Our U.S. based employee benefit programs include medical/dental/vision plans, Employee Stock Purchase Plan, 401(k) plan, tuition reimbursement, life
insurance, short term disability and long term disability. Employee benefit programs are targeted to be approximately at the 50thto 60thpercentile of market data of employee benefit programs for similar high tech companies using the same survey firm used for executive compensation data. Our
employee benefit programs are benchmarked at least annually to ensure that program design reflects current market practices and is cost effective.

Our executive officers, directors and director level equivalents (i.e. employees who are classified as a principal) and members of our Board of Directors are also eligible to participate in the RadiSys Corporation Deferred Compensation
Plan. For further description of our Deferred Compensation Plan, please refer to the narrative following the 2008 Nonqualified Deferred Compensation Table. The gains or losses of participants in the Deferred Compensation Plan based on their
investment choices are not a factor in determining an executives base, incentive bonus target, equity, or any other forms of reward or recognition.

We do not provide our executives with any special perquisites such as club memberships, pension plans, automobile allowances, or dwellings for personal use. Relocation packages to newly hired executives and other



105

##### Table of Contents

newly hired employees are defined within our hiring policy and are based on standard market practices for executive level relocation.

Section IV: Deductibility of Compensation

Section 162(m) of the Internal Revenue Code of 1986, as amended (the Code), limits to $1,000,000 per person the amount that we may deduct for compensation paid to our Chief Executive Officer and four highest compensated
officers who are named executive officers (other than the Chief Executive Officer) in any year. The levels of salary and annual cash incentive bonus we generally pay to our executive officers do not exceed this limit. In addition,
Section 162(m) specifically exempts certain performance-based compensation from the deduction limit. The stock options granted to executive officers under the RadiSys Corporation 2007 Stock Plan are considered performance based for purposes of
Section 162(m) and are therefore not subject to the $1,000,000 limitation. The intent of our Compensation and Development Committee is to design compensation that will be deductible without limitation, where doing so will further the purposes
of our executive compensation program. The Committee will, however, take into consideration various other factors described in this CD&A, together with Section 162(m) considerations, in making executive compensation decisions and could, in
certain circumstances, approve and authorize compensation that is not fully tax-deductible.

|(1) | The amounts included in the Stock Awards and Option Awards columns include stock-based compensation cost we recognized in fiscal 2008 in accordance with Statement of Financial
Accounting Standards No. 123(R) (revised 2004), Share-Based Payment (Stock-based Compensation Cost). We continue to use the Black-Scholes model to measure the grant date fair value of stock options and ESPP shares. The
grant date fair value of stock options that are expected to vest is recognized on a straight-line basis over the requisite service period, which is equal to the option vesting period which is, generally, three years. The grant date fair value of
ESPP shares that are expected to vest is recognized on a straight-line basis over the requisite service period, which is generally 18 months, subject to modification at the date of purchase due to the ESPP look-back feature. For a discussion of the
valuation assumptions used to value the options and shares purchased or to be purchased under the ESPP, see Note 19 to our Consolidated Financial Statements included in our annual report on Form 10-K for the fiscal year ended December 31, 2008.
We compute the grant date fair value of restricted stock as the closing price of our shares as quoted on the Nasdaq Global Market (Nasdaq) on the date of grant or the first date of the underlying service period, whichever occurs first.
The grant date fair value of restricted shares that are expected to vest is recognized on a straight-line basis over the requisite service period, which is three years.

| | accounts and in some cases we make matching contributions to the extent that a participant loses the Company match in our 401(k) plan due to the effect of
participation in the Non-Qualified Deferred Compensation Plan. Participants elect to benchmark earnings on their accounts to the performance of third-party investment funds available to them under the Non-Qualified Deferred Compensation Plan.
Participants select from among the funds available to them. Earnings are calculated and applied to participant accounts daily and may be positive or negative, based on individual fund performance. Although the funds offered to participants under our
Non-Qualified Deferred Compensation Plan differ from those of our 401(k) plan, the number of funds and investment objectives of each fund are similar to those of the 401(k) plan. In accordance with SEC rules and publicly available interpretations of
these rules by the SEC Staff, earnings on deferred compensation invested in third-party investment vehicles, such as mutual funds, need not be reported as compensation on the Summary Compensation Table.

|(2) | Represents estimated payouts during 2008 fiscal year. Under the 2008 Incentive Compensation Plan, minimum levels of non-GAAP operating income and achievement of individual annual
and strategic objectives must be met before there is any payout into the bonus pool under the plan, which means that the minimum payout of any named executive officers individual bonus cannot be determined.

|(3) | There is no target payout under this Plan. Payouts are made at the Maximum amount if maximum revenue targets defined in the Plan are achieved or exceeded. Payouts are pro-rated
between the Threshold and Maximum amounts when revenue results are between minimum and maximum targeted amounts as defined in the Plan.

Narrative Description of Additional Material Factors  Summary Compensation Table & 2008 Grants of Plan-Based Awards Table

Equity Incentive Plans: Stock option and restricted stock units and awards are made under the RadiSys Corporation 2007 Stock Plan. Grants of stock options become exercisable for one-third of the total option shares on
the first anniversary of the date of grant and become exercisable in monthly increments equal to 1/36th of the total option shares, cumulatively, each month thereafter, becoming fully exercisable on the 3rd anniversary of the date of grant. The term
of each option grant is seven years. No consideration is payable by the named executive for grants of restricted stock units/awards. Grants of restricted stock units become vested for one-third of the award shares on each anniversary of the date of
grant.

The grant dates for equity awards during 2008 were established by our Compensation and Development Committee during meetings prior
to each grant date.

Non-Equity Incentive Plans: We maintain a cash-based, pay-for-performance annual Incentive Compensation Plan in which
executive officers are eligible for potential cash bonuses dependent upon the level of achievement of the stated corporate goals and department/individual performance goals, calculated on the basis of a fixed semi-annual target dollar amount.
Depending on the pool funding level, achievement of the stated corporate goals and individual/department performance goals, the bonus may be less than or greater than the target bonus.

The actual bonus payouts are calculated and paid semi-annually. Bonuses earned between January 1 and
June 30 are generally paid in early August; bonuses earned between July 1 and December 31 are generally paid in the following February. Our Compensation and Development Committee determines the actual bonuses based initially on our
achievement of certain financial objectives that are based on our annual targeted operating plan. For 2008 and previous years, the Committee used operating income as the financial objective to determine funding of the bonus pool.

The actual operating income payout percentage is determined at the end of the semi-annual period. The operating income payout percentage payout
multiplied by the target bonus and percent goal achievement for each executive officer determines the executives semi-annual bonus. The Compensation and Development Committee then reviews additional information we provided on the individual
executives performance and his or her departments collective performance, and may make subjective adjustments to the initial calculation.

Depending upon actual department/individual performance results, as determined by the Compensation and Development Committee, an executives final bonus payout may be above or below the initial calculation.
However, generally, the aggregate amount of bonuses paid to all executive officers will not exceed that calculated by the formula stated above, which represents the bonus funding pool.

In September 2007, our Compensation and Development Committee approved the MSBU Plan. The MSBU Plan is a cash-based motivation and reward program for
selected members of our sales and marketing departments who can most directly impact revenues of our media server business. Messrs. Ambrose and Lepiane, two of our named executive officers, participate in the MSBU Plan. Payouts under the MSBU Plan
are determined based on the achievement of pre-determined revenue objectives of our media server business.

Payouts under the MSBU Plan are
calculated and made on a quarterly basis. Payouts are made if the average of the past quarters results, the current quarters results and the forecasted next quarter results of our media server business are at, or above, certain revenue
levels. Payouts are made at 100% of the maximum payout amount if the results for each of the quarters meet the revenue targets and are prorated for lower levels. The MSBU Plan objectives for 2008 were considered difficult to obtain at the maximum
level and have been set at a higher level in 2009 in order to payout at the same level.

For the second, third and fourth quarters of 2008,
our Compensation and Development Committee determined that the media server business stretch objectives achieved by both Mr. Ambrose and Mr. Lepiane were 67.46%, 89.09% and 100%, respectively.

Narrative Disclosure Describing Material Factors

Executives and other select employees can participate in a deferred compensation program. Executive contributions to this program may be made from salary, sales commission payments and/or incentive bonus, excluding the MSBU Plan. A
maximum of 90% of salary and 100% of sales commission payments and/or incentive bonus may be deferred. Base salary and bonus elections apply to compensation earned during the plan year. Sales commission elections apply to compensation paid
during the plan year. Employee contributions are credited to the account balance on the date they would otherwise have been paid to the participant. We only make Company contributions to the Non-Qualified Deferred Compensation Plan in
situations where such contributions are needed to restore any match lost in the 401(k) plan due to the effect of participation in the Non-Qualified Deferred Compensation Plan. Any such matching contributions are credited as soon as practicable
following the end of the plan year.

Participants select from among the funds available to them. Earnings are calculated and applied to
participant accounts daily and may be positive or negative, based on individual fund performance. Although the funds offered to participants under our Non-Qualified Deferred Compensation Plan differ from those of our 401(k) plan, the number of
funds and investment objectives of each fund are similar to those of the 401(k) plan.

Aggregate Distributions are any distributions made
to a participant measured from participation commencement in the Non-Qualified Deferred Compensation Plan to the end of the proxy reporting period. Distributions are paid in the form elected by the participant in the Participation Agreement filed
prior to the

beginning of each plan year. The participant may elect to receive payment during employment or upon separation from service. Available forms of payment
made during employment are lump sum or annual installments over a maximum of five years. Available forms of payment made following a separation from service are lump sum or annual installments over a maximum of 15 years.

POTENTIAL POST-EMPLOYMENT PAYMENTS

Our Compensation and Development Committee has adopted guidelines on severance and change of control agreements to help ensure that written severance or change of control agreements are offered to our executive officers only if special
business needs indicate that such agreements are necessary or advisable.

On December 24, 2008, we entered into a Change of Control
Agreement with our Chief Executive Officer, Scott C. Grout, to update a preexisting agreement to comply with changes in tax laws. Mr. Grouts Change of Control Agreement provides that if we terminate his employment with us (other than for
cause, death or disability) or if he terminates his employment with us for good reason within 12 months following a change of control or within three months preceding a change of control, Mr. Grout is entitled to receive severance pay in a cash
amount equal to 12 months of Mr. Grouts annual base pay at the highest annual rate in effect at any time within the 12-month period preceding the date of termination. Upon such a termination, Mr. Grout would receive 25% of the
severance pay on the date that is six months and one day following termination and the remaining 75% would be paid in six periodic payments on regular paydays, provided that the first remaining payment will be an amount equal to one-half of the
aggregate amount of the remaining payments so long as during the period of remaining payments Mr. Grout does not serve as or become a director, officer, partner, limited partner, employee, agent, representative, material stockholder, creditor,
or consultant of or to, or serve in any other capacity with any business worldwide that shall in any manner (i) engage or prepare to engage in any business which competes directly with us or (ii) solicit, hire, or otherwise assist in any
effort that attempts to employ or otherwise utilize the services of any of our employees. Upon such termination, and in addition to severance pay, Mr. Grout is also entitled to receive COBRA benefits for 12 months. Upon such termination, all
stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other similar awards granted to Mr. Grout shall be immediately exercisable in full in accordance with the applicable
provisions of the relevant award agreement and the plan; and any risk of forfeiture included in any restricted stock or other similar award shall immediately lapse. Stock options (other than those considered Incentive Stock Options) and stock
appreciation rights shall also be amended to permit Mr. Grout to exercise such stock options and stock appreciation rights for a period of time equal to the earlier of (i) the period of 180 days after the date of Mr. Grouts
termination; or (ii) the date that each stock option and stock appreciation right would otherwise expire by its original terms had Mr. Grout not terminated. Had the Change of Control Agreement been in effect and a triggering event occurred
on December 31, 2008, such that Mr. Grout would become entitled to benefits under his Change of Control Agreement, Mr. Grout would have been entitled to receive the payments described below.

On December 24, 2008, we entered into an Employment Agreement including Severance Agreement with Scott C. Grout, to update a preexisting agreement
to comply with changes in tax laws. If Mr. Grouts employment with us is terminated other than for cause and contingent on Mr. Grout signing the Release Agreement, Mr. Grout is entitled to receive severance pay in a lump sum cash
amount equal to 12 months of Mr. Grouts annual base pay at the rate in effect immediately before the date of termination. Had Mr. Grouts employment been terminated by us without cause, and if he had signed a release agreement,
on December 31, 2008, Mr. Grout would have become entitled to receive the payment described below.

change of control, Ms. Harper is entitled to receive severance pay in a cash amount equal to 12 months of Ms. Harpers annual base pay at the highest annual rate in effect at any time within the 12-month period preceding the date of
termination. Upon such termination, and in addition to severance pay, Ms. Harper is also entitled to receive COBRA benefits for 12 months. Upon such termination, all stock options, stock appreciation rights, restricted stock, restricted stock
units, performance shares, performance units and other similar awards granted to Ms. Harper shall be immediately exercisable in full in accordance with the applicable provisions of the relevant award agreement and the plan; and any risk of
forfeiture included in any restricted stock or other similar award shall immediately lapse. Stock options (other than those considered Incentive Stock Options) and stock appreciation rights shall also be amended to permit Ms. Harper to exercise
such stock options and stock appreciation rights for a period of time equal to the earlier of (i) the period of 180 days after the date of Ms. Harpers termination; or (ii) the date that each stock option and stock appreciation
right would otherwise expire by its original terms had Ms. Harper not terminated. Had the Change of Control Agreement been in effect and a triggering event occurred on December 31, 2008, such that Ms. Harper would become entitled to
benefits under her Change of Control Agreement, Ms. Harper would have been entitled to the payments detailed below.

December 22, 2008, we entered into a Change of Control Agreement with our Chief Financial Officer, Brian Bronson, to update a preexisting agreement to comply with changes in tax laws. Mr. Bronsons Change of Control Agreement provides
that if we terminate his employment with us (other than for cause, death or disability), or if his employment terminates as a result of a requirement that he accept a position greater than 25 miles from his current work location or a position of
less total compensation within 12 months following a change of control, Mr. Bronson is entitled to receive severance pay in a cash amount equal to 12 months of Mr. Bronsons annual base pay at the highest annual rate in effect at any
time within the 12-month period preceding the date of termination. Upon such termination, and in addition to severance pay, Mr. Bronson is also entitled to receive COBRA benefits for 12 months. Upon such termination, all stock options, stock
appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other similar awards granted to Mr. Bronson shall be immediately exercisable in full in accordance with the applicable provisions of the

On
December 31, 2008, we entered into a Change of Control Agreement with our Vice President of Sales, Christian Lepiane, to update a preexisting agreement to comply with changes in tax laws. Mr. Lepianes Change of Control Agreement
provides for severance pay in a cash amount equal to 9 months of his annual base pay at the highest annual rate in effect at any time within the 12-month period preceding the date of termination. Mr. Lepiane is entitled to receive the severance

current work location, within three months before, or within twelve months after, a change of control. Upon such termination, and in addition to severance pay, Mr. Lepiane is also entitled to receive COBRA benefits for 9 months. Had the Change
of Control Agreement been in effect and a triggering event occurred on December 31, 2008, such that Mr. Lepiane would become entitled to benefits under his Change of Control Agreement, Mr. Lepiane would have been entitled to the

entitled to receive severance pay in a lump sum cash amount equal to six months of Mr. Lepianes annual base pay at the rate in effect immediately before the date of termination. The payment would be made on the later of the date of
termination or ten days after execution of the release agreement. Mr. Lepiane would also receive COBRA benefits for six months. Had Mr. Lepianes employment been terminated by us without cause, and if he had signed a release

On December 29, 2008, we entered into an Executive Severance Agreement with Anthony Ambrose. If we
terminate Mr. Ambroses employment with us other than for cause and contingent upon Mr. Ambrose signing a release agreement, Mr. Ambrose is entitled to receive severance pay in a lump sum cash amount equal to six months of
Mr. Ambroses annual base pay at the rate in effect immediately before the date of termination. However, the payment may not exceed two times the lesser of (i) the sum of Mr. Ambroses annualized compensation based upon the
annual rate of pay for services provided to us as an employee for the calendar year preceding the calendar year of the termination of Mr. Ambroses employment, or (ii) the maximum amount that may be taken into account under a
qualified plan pursuant to the Code. The payment would be made within 30 days following execution of the release agreement and in any event, no later than the end of the second calendar year following the calendar year of termination.
Mr. Ambrose would also receive COBRA benefits for six months. Had Mr. Ambroses employment been terminated by us without cause, and if he had signed a release agreement, on December 31, 2008, Mr. Ambrose would have become

|(1) | The amounts included in the Stock Awards and Option Awards columns include Stock-Based Compensation cost we recognized in fiscal 2008. We continue to use the Black-Scholes model to
measure the grant date fair value of stock options. The grant date fair value of stock options that are expected to vest is recognized on a straight-line basis over the requisite service period, which is equal to the option vesting period which is,
generally, three years. For a discussion of the valuation assumptions, see Note 19 to our Consolidated Financial Statements included in our annual report on Form 10-K for the fiscal year ended December 31, 2008. A supplemental table following
these footnotes sets forth: (i) the aggregate number of stock awards and option awards outstanding at 2008 fiscal year end; (ii) the aggregate number of stock awards and options awards granted during fiscal 2008; and (iii) the grant
date fair value of equity awards granted by us during fiscal 2008 to each of our directors who was not an executive officer.

in the Non-Qualified Deferred Compensation Plan. Participants elect to benchmark earnings on their accounts to the performance of third-party investment funds available to them under the Non-Qualified Deferred Compensation Plan. Participants select

our Non-Qualified Deferred Compensation Plan differ from those of our 401(k) plan, the number of funds and investment objectives of each fund are similar to those of the 401(k) plan. In accordance with SEC rules and publicly available
interpretations of these rules by the SEC Staff, earnings on deferred compensation invested in third-party investment vehicles, such as mutual funds, need not be reported as compensation on the Director Compensation Table.

|(2) | Stock grants to our Board of Directors are made pursuant to the terms of the RadiSys Corporation 2007 Stock Plan. The exercise price of options granted to non-employee directors
during 2008 was the fair market value of our common stock on the date of grant and the term of each option is seven years. For stock option grants made in 2008, the exercise price was $10.13. Grants of stock options become exercisable for one-third
of the total option shares on the first anniversary of the date of grant and become exercisable in monthly increments equal to 1/36th of the total option shares, cumulatively, each month thereafter, becoming fully exercisable on the 3rd annual
anniversary of the date of grant.

year period to reach this goal. Directors who are our employees receive no separate compensation as directors.

Our Board of Directors is
eligible to participate in the RadiSys Corporation Deferred Compensation Plan. The Deferred Compensation Plan provides the members of our Board of Directors the opportunity to defer up to 100% of compensation (includes annual retainer and committee
fees). Contributions by the members of our Board of Directors are credited on the date they would otherwise have been paid to the participant. We make no contributions on behalf of our Board of Directors members who participate in the Deferred
Compensation Plan.

Participants select from among the fund(s) available to them. Earnings are calculated and applied to participant
accounts daily and may be positive or negative, based on individual fund performance.

Description of Equity Compensation Plans Not Adopted by Shareholders

2001 Nonqualified Stock Option Plan.

In February
2001, we established the 2001 Nonqualified Stock Option Plan, under which 2,250,000 shares of the our common stock were reserved as of December 31, 2006. Grants under the 2001 Nonqualified Stock Option Plan may be awarded to selected employees,
who are not executive officers or directors of the Company. The purpose of the 2001 Nonqualified Stock Option Plan is to enable the Company to attract and retain the services of selected employees of the Company or any parent or subsidiary of the
Company. Unless otherwise stipulated in the plan document, the Board of Directors, at their discretion, determines the exercise prices (which may not be less than the fair market value of the Companys common stock at the date of grant),
vesting periods, and the expiration periods, which are a maximum of 10 years from the date of grant.

On March 21, 2007, our Board of
Directors approved the termination of the RadiSys Corporation 2001 Nonqualified Stock Option Plan, which was effective upon our shareholders approval of the 2007 Stock Plan at the annual meeting on May 15, 2007. Accordingly, no new
options may be granted under the 2001 Nonqualified Stock Option Plan. However, the termination does not affect any outstanding options issued under this Plan.

RadiSys Corporation Stock Plan For Convedia Employees.

On August 31, 2006, our Compensation and Development Committee
adopted the RadiSys Corporation Stock Plan for Convedia Employees (Convedia Stock Plan) for awards to be made in connection with our acquisition of Convedia Corporation. The Convedia Stock Plan was adopted without shareholder approval in
reliance upon the exception provided under Nasdaq Marketplace Rule 4350(i)(1)(A)(iv) relating to awards granted in connection with an acquisition and in connection with the hiring of new employees. The Convedia Stock Plan became effective as of
September 1, 2006. The Convedia Stock Plan permits the granting of stock options, restricted stock and restricted stock units. The maximum number of shares of common stock with respect to which awards may be granted is 365,000 shares (subject
to adjustment in accordance with the Convedia Stock Plan). In order to comply with Nasdaq Marketplace Rule 4350, the awards may only be granted to employees transferred from Convedia Corporation in connection with our acquisition of Convedia
Corporation and in connection with the future hiring of new employees of Convedia Corporation by us. Unless sooner terminated by our Board of Directors, the Convedia Stock Plan will terminate on the tenth anniversary of its effective date of
September 1, 2006. The Convedia Stock Plan provides that the Committee will determine the option price at which common stock may be purchased, but the price will not be less than the fair market value of the common stock on the date the option
is granted. The Committee will determine the term of each option, but no option will be exercisable more than 10 years after the date of grant. The Convedia Stock Plan provides for certain terms and conditions pursuant to which restricted stock
and restricted stock units may be granted under the Convedia Stock Plan. Each grant of restricted stock and restricted stock units must be evidenced by an award agreement in a form approved by the Committee. The vesting of restricted stock or
restricted stock units may be conditioned upon the completion of a specified period of employment, upon attainment of specified performance goals and/or upon such other criteria as the Committee determines.

On March 21, 2007, our Board of Directors approved the termination of the Convedia Stock Plan, which was effective upon our shareholders
approval of the 2007 Stock Plan at the annual meeting on May 15, 2007. Accordingly, no new awards may be granted under the Convedia Stock Plan. However, the termination does not affect any awards previously granted and outstanding under this
Plan.



|Item 13. | Certain Relationships and Related Transactions, and Director Independence
|-------- | -------------------------------------------------------------------------

Our Board of Directors has affirmatively determined that each of C. Scott Gibson, Ken J. Bradley, Richard J. Faubert, Dr. William W. Lattin,
Kevin C. Melia, Carl W. Neun, and Lorene K. Steffes are independent directors as defined by the SEC rules and within the meaning of the Nasdaq Marketplace Rule 4200(a)(15) and, therefore, a majority of our Board of Directors is currently
independent as so defined. Dr. Lattin is also a member

of the Board of Directors of Merix Corporation which builds printed circuit boards for us, and Mr. Bradley is a member of the Board of Directors of
SynQor Inc., which supplies power converters to us. We do not view Dr. Lattins or Mr. Bradleys positions with Merix Corporation or SynQor Inc., as applicable, as a conflict of interest or as a material relationship that would
prevent either of them from being an independent director.

Related Party Transactions Policy

In accordance with our Audit Committee charter, the Audit Committee is responsible for reviewing and approving the terms and conditions of all proposed
related-party transactions required to be disclosed under the SEC rules prior to initiation of any such transaction.

AUDIT COMMITTEE PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT SERVICES OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

The Audit Committee pre-approved all of the services described above that were provided during 2007 and 2008 in
accordance with the pre-approval requirements of the Sarbanes-Oxley Act of 2002. Accordingly, there were no services for which the de minimus exception, as defined in Section 202 of the Sarbanes-Oxley Act, was applicable. The Audit
Committee has considered whether the provision of the services covered by these fees is compatible with maintaining the principal auditors independence. The Audit Committee has adopted a policy for the pre-approval of services provided by the
independent registered public accounting firm. Under the policy, all audit and non-audit services to be performed by the independent registered public accounting firm must be presented to the Audit Committee in writing prior to the commencement of
such services. The proposal must include a description and purpose of the services, estimated fees and other terms of the engagement. The Audit Committee may delegate to the Chairman of the Audit Committee the authority to grant pre-approvals. Any
pre-approvals made by the Chairman pursuant to this delegation shall be presented to the full Audit Committee at its next scheduled meeting following such pre-approvals.
