Market Drivers

We believe
there are a number of fundamental drivers for growth in our target markets, including:



| |  |  | The increasing desire by original equipment manufacturers (OEMs) to utilize standards-based, merchant-supplied modular building blocks and
platforms to develop their systems. We believe more OEMs will see the advantage of combining their internal development efforts with merchant-supplied building blocks and platforms from partners like RadiSys to deliver a larger number of more
valuable new products to get to market faster at a lower total cost.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The high network traffic growth in data and video. High traffic growth in the network will require high density, high speed, high performance systems.
RadiSys ATCA 10G and 40G systems provide 2 to 10 times the density over legacy/traditional systems.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The industry structure is changing in that Telecommunications Equipment Manufactures (TEMs) are focusing more on applications and network
operations, while operators and carriers are focusing more on service delivery and content delivery. RadiSys is benefiting from these market shifts and is providing more platforms to TEMs.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Continued emergence, growth and evolution of applications utilizing 4G or long term evolution (LTE), worldwide inter- operability for
microwave access (WiMAX) networks, Femtocell Gateways, VoIP, IP Communications, Mobile Video, Video Gateways, Video Conferencing, IPTV, IP IVR/ Voice-to-text, IP Messaging, Network Surveillance, Network Security, Military/aerospace and
Packet Inspection, all of which are supported by ATCA.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our Solutions

We provide our customers with advanced infrastructure platforms that enable them to focus their resources and development efforts on their

##### Table of Contents

Broad portfolio of products.Our product lines include a large portfolio of solutions
including fully integrated platforms and application-ready systems with software content. Our market leading product portfolio addresses a large range of customer requirements and applications. We believe that over time many of our customers will
increasingly rely on a smaller set of suppliers who can address a broader set of their solution needs.

Our Strategy

To build market leadership in standards-based advanced infrastructure platforms 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 the leading vendor in
ATCA, IP Media Servers as well as COM Express solutions. We intend to continue to invest significant research and development and sales and marketing resources to build our presence in these market segments.

To develop our offering of higher value platform solutions. Historically, the majority of our revenues had been from the sale of
stand-alone boards or blades. We have spent considerable resources developing application-ready platform solutions that incorporate complete hardware systems and software developed by us. We intend to increasingly focus our development efforts on
moving further up the software stack, positioning us to provide more complete application-ready platforms that provide more value for our customers. 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.

To 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 solutions. Our
global reach allows us to market our solutions to most of the leading system vendors in our target markets. We are also expanding our customer base through entrance into adjacent markets like military/aerospace.

To 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 four years, we acquired Convedia Corporation or Convedia®, a closely-held vendor of IP media servers, and certain assets of the Modular Communications Platform Division (MCPD) business from Intel Corporation
(Intel), which included ATCA and compact peripheral component interconnect (PCI) product lines.

Strategic Progress



| |  |  | Market ShareWe achieved significant traction in Next Generation ATCA and Media Server platforms, which strengthened our #1 market share
position in these target markets. During the year, we announced our new market leading ATCA 40G and enhanced Media Server products.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Design WinsOur Next Generation platforms have been designed into over fifty different programs during the past two years across dozens of
compelling new applications including 3G, 4G/LTE, Femtocell Gateway, Wimax, VoIP, IP Communications, Mobile Video, Video Gateways, Video Conferencing, IPTV, IP IVR/ Voice-to-text, IP Messaging, Network Surveillance, Network Security, Defense and
Packet Inspection.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | CustomersWe are now selling Next Generation products into many of the largest and most innovative communications customers in the market.
Our Next Generation products are sold to 8 of the top 10 Conference Service Providers (CSPs), nine of the top ten (tier one) TEMs, and to more than three dozen different TEMs worldwide.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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



| |  |  | Next Generation GrowthWe almost tripled our Next Generation revenues over the past two years, growing from $36 million in 2007 to
over $100 million in 2009. Gross margin percentages on our Next Generation platforms are in the mid forties and are approximately 20 percentage points higher than our Legacy products.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Asia PresenceWe significantly grew our presence in Asia with a 39% increase in revenue and 87% growth in R&D and Operations
employees in Asia over the past two years. During 2009, we also doubled the size of our R&D facility in Shanghai, China.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our Products

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



| |  |  | complete application-ready platforms for communications networks such as 10G and 40G ATCA platforms and carrier grade media servers (Media
Servers) with significant software content;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | embedded subsystems and functional platforms using ATCA, COM Express and customer-specific proprietary platforms;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | compute, input/output (I/O), storage, inter-networking media processing and packet processing solutions; and
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | software and firmware specific to the aforementioned hardware that includes intelligent platform management interface (IPMI) and hardware
platform interface (HPI) for platform management. We also make all the necessary modifications to 3rd party software, including basic input output system (BIOS), embedded operating systems, protocol stacks and other requisite
software, to provide a platform for our customers use.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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).

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 and 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 have three primary product families: Convedia® Media Servers (CMS), ATCAPromentum®, and CommercialProcelerant .

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

Nokia Siemens Networks was our largest customer in 2009 accounting for 45.9% of total 2009 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 276 engineers and
technicians as of January 30, 2010. We currently have design centers located in the U.S, Canada, China and Malaysia.

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.

##### Table of Contents

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 97 as of January 30, 2010. 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 EMEA region and the Asia Pacific region. EMEA includes Europe, the Middle East and Africa. In each of these geographic markets, 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 2009, global
revenues were comprised geographically of 32.9% from North America, 27.2 % from EMEA and 39.9 % from Asia Pacific. See Note 18Segment Information 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 customers 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

Total manufacturing operations headcount was 222 as of January 30, 2010. For the year ended December 31, 2009 we manufactured
approximately 15% of our own products. We have historically utilized a combination of internal and outsourced manufacturing. During 2009 we initiated a plan to complete our strategic goal of operating based on a fully outsourced manufacturing model.
As part of this plan we have begun to transfer our remaining internally manufactured products from our plant in Hillsboro, Oregon to lower cost manufacturing partners in Asia. We expect the transition to be complete by the third quarter of 2010.

We utilize our offices in Shenzhen, China and Penang, Malaysia to oversee the manufacturing, integration and product testing
efforts conducted by our contract manufacturing partners in these regions. Because many of our products typically have long life reliability requirements, they must undergo particularly rigorous stress testing. In addition, the oversight includes
supply chain management as well as quality control.

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.

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. Some of the microprocessors and other components used in our products are made exclusively by Intel, and we obtain these microprocessors and other



10

##### Table of Contents

components from resellers, integrators, component manufacturers and contract manufacturers. 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 and expect to reach a fully outsourced manufacturing model by the third quarter of 2010. While our contract manufacturing agreements are on terms and conditions
that we believe are customary for the industry and do not impart any rights of exclusivity and while our contract manufacturers do not supply any specialized know-how or intellectual property necessary to manufacture our 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, 2009, our backlog was approximately $51.4 million, compared to $34.4 million as of December 31, 2008. We
include in our backlog statistic all purchase orders scheduled for delivery within 12 months.

Intellectual Property

We hold 32 U.S. and 26 foreign utility patents, three U.S. design patents and have two U.S. and four 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, 2010, we had 719 employees, of which 623 were regular employees and 96 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.

|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, 2009, 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 the significant percentage of our sales to 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 2009, 2008 and 2007, we derived 64.6%, 59.7%, and
66.0%, respectively, of our revenues from our five largest customers during these periods. These five customers were Danaher, Nokia Siemens Networks, Philips Healthcare, Okaya (end customer Fujitsu) and Miltope, which each purchase a variety of
products from us. During 2009, 2008 and 2007, revenues attributable to Nokia Siemens Networks were 45.9%, 43.5%, and 44.8%, respectively. 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, our products are building blocks for our customers products and,
in certain instances, our 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 ability, as well as our contract manufacturers ability, to meet customer demand depends largely on our ability to obtain raw materials and a
reduction or disruption in the availability of raw materials could negatively impact our business.

The continued
global economic contraction has caused many of our component suppliers to reduce their manufacturing capacity. As the global economy improves, our component suppliers are experiencing and will continue to experience supply constraints until
they expand capacity to meet increased levels of demand. These supply constraints may adversely affect the availability and lead times of components for our products. Increased lead times mean we may have to forsake flexibility in aligning
our supply to customer demand changes and increase our exposure to excess inventory since we may have to order material earlier and in larger quantities. Further, supply constraints will likely result in increased expedite and overall
procurement costs as we attempt to meet customer demand requirements. In addition, these supply constraints may affect our ability, as well as our contract manufacturers ability, to meet customer demand and thus result in missed
sales opportunities and a loss of market share, negatively impacting revenues and our overall operating results.

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 several 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 us 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.

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.

The growth of our
business is dependent in part on successfully implementing our international expansion strategy.

During 2009, we
launched two significant strategic initiatives within manufacturing operations and engineering. As part of the initiatives, we plan to transition to a fully outsourced manufacturing model, which will transfer remaining manufacturing from our
manufacturing plant in Hillsboro, Oregon to our contract manufacturing partners in Asia. The plan also includes consolidating our North American research and development positions and programs and expanding our research and development operations in
Shanghai, China. As part of this expansion in China, we have doubled our engineering space and have begun increasing headcount in that location.

Both of these strategic initiatives increase our international presence, which along with our existing international operations involve risks inherent in doing business on an international level. These
risks include the following:



| |  |  | difficulties in managing operations due to distance, language, and cultural differences;
| | - |  | ----------------------------------------------------------------------------------------





| |  |  | different or conflicting laws and regulations;
| | - |  | ----------------------------------------------



| |  |  | accounting (including managing internal control over financial reporting in our non-U.S. subsidiaries), tax and legal complexities arising from
international operations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | burdensome regulatory requirements and unexpected changes in these requirements, including data protection requirements;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | political and economic instability;
| | - |  | -----------------------------------



| |  |  | fluctuations in currency exchange rates; and
| | - |  | --------------------------------------------



| |  |  | different laws and regulations surrounding taxes and their potentially adverse consequences.

Our foreign currency exchange risk management program reduces, but does not eliminate, the
impact of currency exchange rate movements. If we cannot manage our international operations successfully, our business, results of operations and financial condition could be adversely affected.

Our customers and suppliers are exposed to risks associated with the worldwide economic downturn and financial turmoil that could adversely affect
their payment of our invoices or the continuation of their businesses at the same level.

The businesses of many of
our customers and suppliers are exposed to risks related to the current economic environment. A number of our customers and suppliers have been and may continue to be adversely affected by the worldwide financial turmoil, disruptions to the capital
and credit markets and decreased demand for their products and services. In the event that any of our large customers or suppliers, or a significant number of smaller customers and suppliers, are adversely affected by these risks, we may face
disruptions in supply, further reductions in demand for our products and services, failure of customers to pay invoices when due and other adverse effects that may have a material adverse effect on our business, financial condition and operating
results.

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



| |  |  | rapidly develop and produce these products at competitive prices;
| | - |  | -----------------------------------------------------------------



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



| |  |  | provide effective technical and post-sales support for these new products as they are deployed.
| | - |  | -----------------------------------------------------------------------------------------------

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.

Our revenue growth expectations for our next-generation products are highly dependent upon successful ramping of our design wins. The time
between when we achieve a design win with a customer and when we begin shipping to that customer at production levels generally has been shortened with our standards-based model. In some cases there is no time in between when a design win is
achieved and when production level shipments begin. With many new design wins with our ATCA platforms and our COM Express modules, customers may require us to provide customization to our products. In addition, customers may require
significant time to port their own applications to our systems. Customization of our products as well as porting of customer specific applications can take six to twelve months and in some circumstances can be as long as 24 months. 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. Customer projects 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 and 4G wireless technologies, IPTV, advanced multimedia applications, Femtocell 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 growth and gross margin expectations.

Our business depends on conditions in the communications networks 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 2009,
we derived 78.5% and 21.5% of our revenues from the communications networks and commercial systems markets, respectively. In 2008, we derived 79.2% and 20.8% of our revenues from the communications networks and commercial systems markets,
respectively. In 2007, we derived 76.7% and 23.3% of our revenues from the communications networks and commercial systems markets, respectively. We believe that our revenues will continue to be derived primarily from these two markets.
Communications networks revenues include, but are not limited to, sales to Alcatel Lucent, Avaya, Bigband Networks, British Telecom, Cisco Systems, Comverse, Global Crossing, Huawei Technologies Co., IBM, IP Access, Italtel, Kineto Wireless, LG
Nortel, Motorola, Nanjing , NEI (end customer Danaher), Nokia Siemens Networks, PGi (formerly Premiere Global), Qwest, Samsung, Tellabs, Tomen (end customer NEC), Viasat, Webex, West Corporation, and ZTE. Commercial systems revenues include, but are
not limited to, sales to AAI Textron, Agilent Technologies, Arrow Electronics, Danaher, Diebold, GE Healthcare, HP, IBM, iRobot, Miltope, Mindray, Philips Healthcare, and Siemens Medical. Generally, our products are building blocks for our
customers products and, in certain instances, 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 the limited number of direct and indirect suppliers, or in some cases, one supplier, for
some of the components we and our contract manufacturers use, as well as the limited number of contract manufacturers who 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.

There are only a limited number of direct and indirect suppliers, or in some cases, only one supplier, for a continuing supply of the components we and our contract manufacturers use in the manufacture of
our products and any disruption in supply could adversely impact our financial performance. For example, Intel is the only indirect supplier of some microprocessors and other components used in our products. We obtain these microprocessors and other
components from resellers, integrators, component manufacturers and contract manufacturers. Alternative sources of components that are procured from one supplier or a limited number of suppliers could 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 have almost completed the transition to a fully outsourced model of manufacturing. In 2009, 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 from these
customers, we must convince them 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.

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 or custom solutions, 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. In addition, the current state of the economy could further delay or prolong the transition or adoption
of standards-based products. During 2009, 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 choose not to use standards-based products to the extent, or in the timeframe that we are projecting. If customers 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. These 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. If we are unable to accurately anticipate future demand and the technologies that will gain market acceptance, or
appropriately allocate personnel and financial resources to meet such demand, our revenues, profitability and financial condition could be materially adversely affected.

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. 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

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 have sought to optimize our
operational capabilities and efficiencies and focus our efforts and expertise through business restructurings. In the future we may decide to engage in discrete restructurings of our operations if business or economic conditions warrant. 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, which 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 2009, 2008, and 2007, as measured by delivery destination, we derived 0.9%, 1.6% and 2.1%, respectively, of our revenues from Canada and
Mexico, 27.2%, 37.0% and 40.6%, respectively, of our revenues from EMEA and 39.9%, 30.5% and 26.8%, respectively, from Asia Pacific. For the year ended December 31, 2009, approximately 85% of our unit volume consisted of products manufactured
by our Asian contract manufacturing partners. Continuing this trend, during 2009 we continued to globally diversify our operations and began our transition to a fully outsourced manufacturing model. As part of this plan we have begun to transfer our
remaining internally manufactured products from our plant in Hillsboro, Oregon to lower cost manufacturing partners in Asia. 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 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 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.

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 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, 2009, as
compared to the year ended December 31, 2008, however our stock price volatility has increased during the fourth quarter of 2009, which along with unfavorable changes in the other assumptions used to value our share-based payment arrangements
could result in future increased compensation 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. 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

##### Table of Contents

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, 2009, we had 2.7 million outstanding stock options awarded to our employees with an average grant price of $12.91. In addition, approximately 55% of outstanding options were issued at a price above the closing
price of our stock on December 31, 2009. 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, 2009, we had 1.3 million outstanding stock
options awarded to our executive management team with an average grant price of $12.96. 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



22

##### Table of Contents

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, 2009, 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 and any desired dilution
mitigation will be limited to the extent that our stock price remains below $23.08 per share.

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. Because the maximum number of shares deliverable under the capped call transaction is less than the number of shares issuable upon
conversion of the 2013 convertible senior notes, we refer to this effect as dilution mitigation. If, however, the market value per share of our common stock exceeds the cap price of the capped call transaction of $23.08 per share, as
measured under the terms of the capped call transaction, no additional shares would be delivered under the capped call transaction, and correspondingly, 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.

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



| |  |  | expect to purchase our common stock in the open market and/or enter into various derivatives and/or enter into various derivative 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. For further information regarding the mechanics of our
capped call transaction refer to our discussion in the Liquidity and Capital Resources section of Item 7.Managements Discussion and Analysis of Financial Condition and Results of Operations.

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

We currently hold investments in auction rate securities
(ARS), the majority of which represent interests in collateralized debt obligations supported by pools of government-backed student loans with S&P AAA or Moodys Aaa ratings at the time of purchase. During the first quarter of
2008, our portfolio of ARS investments experienced multiple failed auctions as the amount of securities submitted for sale exceeded the amount of



24

##### Table of Contents

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. During the fourth quarter of 2008, we accepted a settlement offer from our investment bank, UBS AG, associated with the failed auctions. Under the terms of the offer, we have the
right to require the bank to repurchase at par value our ARS investments at any time between June 30, 2010 and June 30, 2012. As we plan to require UBS to repurchase our ARS on June 30, 2010, these investments have been classified as
short-term investments. For our ARS settlement right, we have elected the fair value option for financial assets and financial liabilities.

We record our ARS investments and corresponding settlement right at fair value in accordance with GAAP for fair value measurements, using level 3 inputs, as defined in Note 3Fair Value of
Financial Instrumentsof the Notes to the Consolidated Financial Statements. We considered various inputs to estimate the fair value of our ARS investments at December 31, 2009, 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 our ARS holdings.

We determined the fair value of our ARS settlement right based on the difference between the estimated fair value of the ARS and the par
value of the ARS. This difference was then discounted based on the future date when the settlement right is expected to be exercised to account for the time value of money. The discount rate used took into consideration the risk free rate as well as
UBSs credit quality. The valuation of our ARS settlement right is contingent upon the financial viability of our investment bank and accordingly, we have assigned a credit risk component 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, the realizable value of our ARS settlement right would be adversely affected. 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.

Our 2013 convertible
senior notes have a conversion price of equivalent to $13.03 per share. 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 $23.08 per share for 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.

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.

The closing price as
reported on the NASDAQ Global Select Market on March 12, 2010 was $8.90 per share. As of March 12, 2009, there were approximately 269 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, the NASDAQ Index, the NASDAQ Computer Manufacturers Index, and the NASDAQ Telecommunications Index for the period of December 31, 2004 through December 31, 2009. The graph reflects the investment of $100 on
December 31, 2004 in our stock, the S&P 500 Index, the NASDAQ Index, and in published industry indices.

Historically, we have included the S&P 500 Index as well as the NASDAQ Computer Manufacturers Index in our performance graph. For the year ended December 31, 2009 for comparison purposes, we have also included the NASDAQ Index and
NASDAQ Telecommunications Index, which we intend to use going forward. Due to changes in our business model over the past several years, we now believe these indices provide a better comparison between the performance of our stock and that of other
companies in our line of business and broader market.

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 are a leading
provider of application-ready software and hardware platforms for use in the communications, multi-media, military/aerospace and medical markets. RadiSys innovative and market leading technologies help equipment manufacturers and network
operators bring the most advanced products and services to market faster and more economically. Our product offerings include our media server products, ATCA products and Commercial products. We enable our customers to focus their resources and
development efforts on their key areas of differentiation, while allowing them to provide higher value systems with a time-to-market advantage at a lower total cost.

Financial ResultsTotal revenue was $304.3 million, $372.6 million and $325.2 million in 2009, 2008 and 2007, respectively. Backlog was approximately $51.4 million, $34.4 million and $33.8
million at December 31, 2009, 2008 and 2007, respectively. Backlog includes all purchase orders scheduled for delivery within 12 months. The decrease in revenues during 2009 compared to 2008 was driven by decreased revenues in all of our
product groups. The increase in revenues during 2008 compared to 2007 was due to increases in revenues in the communications networks market of $45.4 million along with increased revenues of $2.0 million in the commercial systems market.

Gross margins as a percentage of revenues were 30.5%, 25.8% and 22.1% for 2009, 2008 and 2007, respectively. The increase in gross margin
as a percentage of revenues was driven by favorable changes in our product mix, a reduction in the amortization of purchased technology, and lower charges incurred for warranty and excess and obsolete inventories. The favorable change in our product
mix resulted from a larger percentage of overall revenues coming from our higher margin next-generation communications networks products. Amortization of purchased technology decreased by $7.9 million during 2009 from 2008. This was driven by assets
which have become fully amortized over the past two years, which accounted for $4.9 million of the decrease, along with the extension of the useful lives of various intangible assets in the fourth quarter of 2008, which resulted in a decrease of
$3.1 million in amortization costs. In addition, we incurred lower charges for excess and obsolete inventory primarily due to the continued realization of internal process improvements during 2009.

During the year ended December 31, 2009, we also incurred in the first quarter a $42.0 million charge associated with the establishment
of a full valuation allowance against our U.S. net deferred tax assets. We recognize deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we considered all available positive
and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based upon our review of all positive and negative evidence, including our
projected three year U.S. cumulative pre-tax book loss and taxable loss, we concluded that a full valuation allowance should be recorded against our U.S. net deferred tax assets during 2009.

Net loss was $42.6 million, $67.3 million, $21.2 million in 2009, 2008 and 2007, respectively. Net loss per share was $1.81, $2.98 and $0.97
for 2009, 2008 and 2007, respectively. The decrease in net loss during 2009 from 2008, was due primarily to the absence of goodwill impairment charges, which totaled $67.3 million during 2008. This was offset by increased income tax provisions
during 2009 driven primarily by the establishment of our deferred tax valuation allowance in the amount of $42.0 million.

Cash and cash equivalents amounted to $100.7 million and $74.0 million at December 31, 2009 and December 31, 2008, respectively. The increase in cash and cash equivalents was primarily due to operating cash flows in the amount of
$25.4 million and financing cash flows of $6.0 million. These positive cash flows were partially offset by cash outflows from investing activities in the amount of $4.8 million. Investing cash outflows were driven by capital expenditures primarily
related to upgrades and expansion of our internal infrastructure as well as costs due to our transition to a fully outsourced manufacturing model. Our investments, which include our ARS settlement right, remained relatively consistent and totaled
$62.2 million at December 31, 2009 and

##### Table of Contents

$62.3 million at December 31, 2008. Decreases in our investments were driven by changes in the variables of our valuation model along with sales of ARS during 2009. These decreases were
almost fully offset by increases in the value of our ARS settlement right during 2009.

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. 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.

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



31

##### Table of Contents

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 Consolidated Balance Sheets.

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 Consolidated 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, 2009
amounted to $10.7 million and $9.9 million, respectively.

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 us. 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.

##### Table of Contents

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.

Income Taxes

Income tax accounting 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. To
the extent that we determine that we will not be able to realize all or part of our net deferred tax assets in the future, we adjustment the valuation allowance accordingly. The net deferred tax assets amounted to $16.8 million as of
December 31, 2009. 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, 2009, 30.8% of our accounts receivable was due from our largest customer. 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, 2009 and 2008, there were no significant account balances reserved for and during 2009 the
allowance for doubtful accounts decreased by $4,000 as a result of 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

Because we have a history of paying severance benefits, expenses associated with exit or disposal activities are recognized when probable and estimable.

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

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 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 or if support is the only undelivered element, revenue is recognized ratably over the service period of the support.
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

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 17.5%, 15.2% and 9.9% for the years ended December 31, 2009, 2008 and 2007, 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 applicable software revenue recognition criteria.

Software royalties and licenses

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. 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. The fair value of our post-contract support has been determined by renewal rates within our 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. 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.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 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. 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.

Stock-based Compensation

Equity instruments are granted to
employees, directors and consultants in certain instances, as defined in the respective plan agreements. In 2009, 2008, and 2007, we issued stock options, restricted stock units under our 2007 stock plan and long-term incentive plan
(LTIP) and stock under employee stock purchase plan (ESPP).

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

##### Table of Contents

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 units granted under our 2007 stock plan and LTIP is equal to the closing price of our shares as quoted on the NASDAQ Global Select Market on the
date of grant. The grant date fair value of restricted stock issued under our 2007 stock plan that are expected to vest is recognized on a straight-line basis over the requisite service period, which is three years. The estimate of the number of
options, ESPP shares, restricted stock unit awards issued under our 2007 stock plan expected to vest is determined based on historical experience.

The grant date fair value of restricted stock units issued under our LTIP that are expected to vest is recognized ratably over the service period of the award. The service period of restricted stock units
issued under our LTIP is equal to the period of time over which performance objectives underlying the awards are expected to be achieved. The estimate of the number of restricted stock units, issued under our LTIP, expected to vest is determined
based upon our financial results as compared to the performance goals set for the award and is adjusted quarterly.

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



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



| |  |  | illiquidity associated with one year required holding period for ESPP shares.
| | - |  | -----------------------------------------------------------------------------

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.

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. 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 17Employee Benefit Plansof the Notes to
the Consolidated Financial Statements for a further discussion on stock-based compensation.

The LTIP performance awards are valued at the closing price of our common stock on the grant
date which was $8.18 on October 1, 2009. The corresponding compensation cost of each LTIP award is expensed ratably over the measurement period of the award. Since the number of shares that may be issued under the LTIP and the measurement
period are both variable, we reevaluate the LTIP awards on a quarterly basis and adjust the number of shares expected to be awarded based upon our financial results as compared to the performance goals set for the award. Adjustments to the number of
shares awarded, and to the corresponding compensation expense, are made on a cumulative basis at the date of adjustment based upon the estimated probable number of shares to be awarded. Adjustments made to compensation expense resulting from a
change in the estimated probable vesting date of the awards are made on a prospective basis. For the year ended December 31, 2009, we recorded $452,000 in stock compensation expense associated with LTIP awards.

On October 5, 2009, we announced an offer to exchange certain outstanding options for restricted stock units or new options. Eligible
employees were permitted to exchange some or all of their outstanding options, with an exercise price greater than $9.44 per share (which is equal to the 52-week high closing price of our common stock as of the start of this offer), that were
granted on or before October 5, 2008, whether vested or unvested, for restricted stock units, except for employees in Canada who received new stock options with new vesting schedules and exercise prices. All employees of RadiSys and its
subsidiaries, other than members of our Board of Directors, executive officers and employees located in the Netherlands and Israel were eligible to participate in the exchange offer, so long as they remain employed through the expiration date of the
offer. The option exchange took place on November 3, 2009. Pursuant to the option exchange 848,800 eligible options were canceled and replaced with 169,600 restricted stock units and 35,000 stock options. The new restricted stock units and
stock options have a new three year vesting period that began on November 3, 2009. The exchange resulted in $173,000 in additional stock compensation expense which will be recognized over the new three year vesting period.

Results of Operations

The following table sets forth certain operating data as a percentage of revenues for the years ended December 31, 2009, 2008 and 2007.

During the first quarter of 2009, we adopted the cash conversion subsections of ASC Topic 470-20 Debt with Conversion and Other
OptionsCash Conversion (ASC Topic 470-20). The Cash Conversion Subsections are effective for our previously outstanding 1.375% convertible senior notes due 2023. Although, our 2023 convertible senior notes were retired
as of December 31, 2009, we were still required to retrospectively apply Cash Conversion Subsections in all periods presented that include our 2023 convertible senior notes. As a result of this retrospective application, our opening
accumulated deficit and additional paid in capital balances were adjusted by ($9.6 million) and $16.2 million, net of tax, respectively. In addition, amounts previously reported in our Consolidated Statements of Operations for interest expense,
other income (expense), net, income tax expense (benefit), and net loss have been adjusted as a result of adoption.

Communications Networks Product Group

Revenues in the communications networks market decreased by $56.3 million or 19.1%, to $238.9 million in 2009 from $295.2 million in 2008 due
to decreased revenues from both submarkets within our communications networks product group. Both product groups were affected by continued economic weakness during 2009. The decreases in revenues from our legacy/traditional communications networks
products were further driven by the maturity of the products within this group as they approach end of life. The decline in revenues from our next-generation communications networks products was further affected by the recognition of approximately
$8.7 million in previously deferred revenues during 2008.

Commercial Products Group

Revenues in the commercial systems market decreased by $12.0 million, or 15.5%, to $65.4 million in 2009 from $77.4 million in 2008. These
declines were primarily driven by the maturity of our legacy/traditional products within our commercial products group. These decreases were also affected by a decline in demand caused by general global economic weakness in all of our submarkets
including medical and test and measurement equipment. Revenues from our medical product group declined by $3.3 million, or 11.3%, to $26.3 million during 2009 from $29.6 million in 2008. Revenues from our test and measurement product group declined
by $5.4 million, or 42.6%, to $7.3 million in 2009 from $12.7 million in 2008.

From a geographic perspective, non-North American revenues by delivery destination decreased
by $47.4 million, or 18.8%, to $204.1 million during 2009 from $251.5 million during 2008. As a percentage of total revenues, non-North American revenues by delivery destination remained relatively consistent while the percentage of revenues by
region continued to shift from the EMEA region to the Asia Pacific region. Specifically, non-North American revenues by delivery destination accounted for 67.1% of total revenues during 2009, down from 67.5% during 2008. In addition, revenues from
the Asia Pacific region increased by $8.0 million in 2009 and represented 39.9% of total revenues, up from 30.5% in 2008. Revenues from the EMEA region decreased $55.3 million during 2009 and represented 27.2% of total revenues, down from 37.0% in
2008. The shift in revenues from the EMEA region to the Asia Pacific region was largely driven by continued changes to our existing customers integration processes which have been transitioning to this region coupled with an increased
percentage of our revenues being derived from our next-generation communications networks products sold to customers in the Asia Pacific region. Revenues from North America decreased by $21.0 million, or 17.3%, to $100.1 million during 2009 from
$121.1 million in 2008. Revenues from North America remained flat as a percent of total revenues and represented 32.9% during 2009, up from 32.5% during 2008. The decrease in overall revenues from North America was attributable to general economic
weakness as well as the maturity of products being sold to customers in this region.

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 Margin

Gross margins as a percentage of revenues increased by
4.7 percentage points to 30.5% in 2009 from 25.8% in 2008. The increase in gross margin as a percentage of revenues was driven by a reduction in the amortization of purchased technology, favorable changes in our product mix, and lower charges
incurred for warranty and excess and obsolete inventories. Amortization of purchased technology decreased by $7.9 million, or 55%, to $6.5 million in 2009 from $14.4 million in 2008. This was driven by assets which have become fully amortized over
the past two years, which accounted for $4.9 million of the decrease, along with the extension of the useful lives of various intangible assets in the fourth quarter of 2008, which resulted in a decrease of $3.1 million in amortization costs during
2009. The favorable change in our product mix resulted from a larger percentage of overall revenues coming from our higher margin next-generation communications networks products. We incurred reduced charges for excess and obsolete inventory
primarily due to the continued realization of internal process improvements implemented over the last few years.

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 decreased $7.4 million, or 15.1%, to $41.9 million in 2009 from $49.3 million in 2008. This
decrease, compared to the same periods in 2008, is primarily due to lower payroll costs, which decreased by $3.2 million, or 14.2%, to $19.4 million in 2009 from $22.6 million in 2008. Decreases in payroll costs resulted from restructuring
activities undertaken during 2008 and 2009. The decrease was further driven by decreased incentive compensation and bonus costs, which decreased by $2.5 million, or 37.2%, to $4.3 million in 2009 from $6.8 million in 2008. The decrease in incentive
compensation and bonus costs were a direct result of restructuring activities along with a lower payout factor for employee incentive compensation plans associated with the achievement of corporate objectives. Due to our restructuring activities
initiated during 2009, R&D expenses are expected to further decrease during 2010.

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 decreased $5.7 million, or 11.3%, to $45.1 million
in

2009 from $50.8 million in 2008. This decrease was largely driven by lower incentive compensation costs, which decreased by $2.5 million, or 24.7%, and totaled $7.5 million in 2009 down from $9.9
million in 2008. The decrease in incentive compensation costs were driven by a lower payout factor for employee incentive compensation plans associated with the achievement of corporate objectives. The decrease was further driven by decreased travel
costs of $837,000 and a decrease in overall payroll costs of $765,000. Our decreased payroll costs resulted from restructuring activities undertaken during 2008 and 2009 and our overall headcount decreased by 15 to 221 employees in 2009 from 236
employees in 2008.

Stock-based Compensation Expense

Stock-based compensation expense consists of amortization of stock-based compensation associated with unvested stock options, restricted
stock units issued to employees under the 2007 stock plan and long-term incentive plan (LTIP), and employee stock purchase plan (ESPP). During the year ended December 31, 2009, we incurred $8.5 million in stock-based
compensation. During the year ended December 31, 2008, we incurred $9.6 million in stock-based compensation expense. The decrease in stock-based compensation expense was driven by older share based payment awards becoming fully vested along
with decreased costs of new awards, which were the result of our overall lower stock price.

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

On October 5, 2009, we announced an offer to
exchange certain outstanding options for restricted stock units or new options. Eligible employees were permitted to exchange some or all of their outstanding options, with an exercise price greater than $9.44 per share (which is equal to the
52-week high closing price of our common stock as of the start of this offer), that were granted on or before October 5, 2008, whether vested or unvested, for restricted stock units, except for employees in Canada who received new stock
options with new vesting schedules and exercise prices. All employees of RadiSys and its subsidiaries, other than members of our Board of Directors, executive officers and employees located in the Netherlands and Israel were eligible to participate
in the exchange offer, so long as they remain employed through the expiration date of the offer. The option exchange took place on November 3, 2009. Pursuant to the option exchange 848,800 eligible options were canceled and replaced with
169,600 restricted stock units and 35,000 stock options. The new restricted stock units and stock options have a new three year vesting period that began on November 3, 2009. The exchange resulted in $173,000 in additional stock compensation
expense which will be recognized over the new three year vesting period.

Intangible Assets Amortization

Intangible asset amortization expense included in operating expenses consists of the amortization of trade names and
customer related intangible assets. Intangible assets amortization expense included in results of operations was $2.6 million and $4.6 million in 2009 and 2008, respectively. Intangible assets amortization decreased due to the extension of the
useful lives of various intangible assets in the fourth quarter of 2008. 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
9Accrued Restructuring and Other Chargesof the Notes to the Consolidated Financial Statements. During 2009 and 2008, we recorded restructuring and other charges and reversals as described below.

Second Quarter 2008 Restructuring.During the second quarter of 2008, we initiated a restructuring plan that included the elimination
of 23 positions. The restructuring was primarily initiated 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. All restructuring activities were completed during the first quarter of 2009. No charges associated with the second quarter
2008 restructuring plan were incurred during 2009.

First Quarter 2009 Restructuring.During the first quarter of 2009,
we initiated a restructuring plan that included the elimination of 29 positions. The restructuring was initiated to align our costs with our annual operating plan. During 2009 we incurred a total of $1.5 million in restructuring charges, which were
comprised almost entirely of employee payroll related severance costs. Included in these costs were charges related to the modification of equity awards to certain employees included in this restructuring activity. We expect all activities
associated with this restructuring to be completed by first quarter of 2010.

Second Quarter 2009 Restructuring. During
the second quarter of 2009, we initiated a restructuring plan that includes the elimination of 115 positions and the relocation of eight employees as part of two strategic initiatives within manufacturing operations and engineering. As part of the
initiative, we plan to transition to a fully outsourced manufacturing model, which will transfer remaining manufacturing from our manufacturing plant in Hillsboro, Oregon to our manufacturing partners in Asia. The plan also includes consolidating
our North American research and development positions and programs, and specifically transferring current projects from our design center in Boca Raton, Florida, to other existing R&D centers. During 2009 we incurred a total of $3.1 million in
restructuring charges, which consisted of accrued severance obligations, healthcare benefits, relocation incentives and related payroll taxes. The balance also includes legal expenditures as well as contract termination fees. We currently
expect to incur approximately $200,000 in additional restructuring charges over the next four months associated with the second quarter 2009 restructuring plan. These additional charges are primarily related to employee relocation costs. This
transition is expected to be complete by the third quarter of 2010.

Fourth Quarter 2009 Restructuring. During the
fourth quarter of 2009, we initiated a restructuring plan that includes the elimination of 22 positions at various locations throughout the company. The primary focus of this initiative is to align expenses with our 2010 operating plan objectives,
which include the need to continue focusing on lowered costs. During 2009, we incurred $882,000 in charges associated with this restructuring plan, which consisted of severance and related payroll costs as well as healthcare benefits. We expect all
activities associated with this restructuring plan to be completed by the fourth quarter of 2010.

Interest Expense

During 2009, interest expense includes interest incurred on our convertible notes and our new lines of credit.
Interest expense decreased $2.5 million, or 51.3%, to $2.4 million in 2009 from $4.9 million in 2008. The decrease in interest expense in 2009 compared to 2008 was driven by the adoption of the ASC Topic 470-20 during the first quarter of 2009,
which resulted in the retrospective recognition of interest expense in the amount of $2.2 million during 2008. Refer to Note 12Convertible Debtof the Notes to the Consolidated Financial Statements for further details of the interest
costs resulting from our adoption of ASC Topic 470-20.

Interest Income

During 2009, interest income decreased $2.0 million, or 63.3%, to $1.1 million in 2009 from $3.1 million in 2008. Interest income decreased
as a result of a decline in the average yield on investment holdings. The decline in our average investment yield was driven primarily by lower reset interest rates associated with our ARS as well as a decline in earnings from our cash equivalents.

Income Tax Provision

We recorded tax expense and benefit of $39.3 million and $9.5 million for the years ended December 31, 2009 and 2008, respectively. Our current effective tax rate differs from the statutory rate
primarily due to a full valuation allowance provided against its U.S. net deferred tax assets, revaluation of the Canadian net deferred tax asset and Canadian research and experimental development claims.

At December 31, 2009, we had net deferred tax assets of $16.8 million. In addition, we had valuation allowances of $48.4 million and
$5.6 million, as of December 31, 2009 and 2008, respectively. The $48.4 million valuation at December 31, 2009 represents a full valuation allowance against our U.S. deferred tax assets. The $5.6 million valuation allowance at
December 31, 2008 was related primarily to certain U.S. net operating loss and tax credit carryforwards. In evaluating our valuation allowance, we considered all available positive and negative evidence, including scheduled reversals of
deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based on our review of all positive and negative evidence, including a three year U.S. cumulative pre-tax loss and taxable loss, it
was concluded that a full valuation allowance should be recorded against our U.S. net deferred tax assets. In the event we were to determine that we would not be able to realize all or part of our foreign 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 all or a portion of the U.S. net
deferred tax assets, we would reverse 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, 2009 will be realized.

We are subject to income taxes in the U.S. and ten foreign countries, and on occasion, we have been subject to corporate income tax audits. Specifically, we are currently under examination in the U.S. and
Canada. In determining the amount of income tax liabilities for uncertain tax positions, we have evaluated whether certain tax positions are more likely than not to be sustained by taxing authorities. We believe that we have adequately provided in
our financial statements for additional taxes that we estimate may result from these examinations. To the extent the ultimate outcome of the examinations differs from the amounts provided for as uncertain tax positions either additional expense or
benefit will be recognized in the period in which the examinations are effectively settled.

In the fourth quarter of 2009,
the Internal Revenue Service (IRS) commenced its examination of the 2007 and 2008 years. Subsequent to December 31, 2009, the IRS has issued and we have agreed to a Notice of Proposed Adjustment. The Proposed Adjustment was provided
in full as an uncertain tax position at December 31, 2009, but did not have a material impact on our Consolidated Financial Statements.

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 networks and commercial systems markets of $45.7 million and $1.6 million,
respectively.

Communications Networks Product Group

Revenues in the communications networks 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.

Commercial
Products Group

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.

##### Table of Contents

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 by destination in the Asia Pacific region increased by $26.2 million 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.

Gross Margin

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 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

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 unit awards and ESPP shares
unvested and outstanding on January 1, 2006 and new stock options, restricted stock units and ESPP shares granted for the year ended December 31, 2008.

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):

Restructuring and Other Charges

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 completed all activities associated with the restructuring by March 31, 2009.

Interest Expense

Interest expense includes interest incurred on our convertible notes and our new lines of credit. Interest expense decreased $2.4 million, or 51.3%, from $7.3 million in 2007 to $4.9 million in 2008. The
decrease in interest expense in 2008 compared to 2007 was driven by the adoption of ASC Topic 470-20 during the first quarter of 2009, which resulted in the retrospective recognition of interest expense in the amount of $2.2 million and $5.7 million
during 2008 and 2007, respectively. Offsetting this decrease from 2008 to 2007, were increased interest costs 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.

##### Table of Contents

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 million.

Income Tax Provision

We recorded tax benefits of $10.3 million and $8.1 million for the years ended December 31, 2008 and 2007, respectively. Our effective tax rate for the year ended 2008 was a tax benefit of 12.6%
compared to a tax benefit of 25.5% for the year ended December 31, 2007. Our current effective tax rate differs from the statutory rate primarily due to the impact of goodwill impairment, the revaluation of certain net deferred tax assets due
to changes in foreign currency exchange rates, and research and development tax credits generated in 2008.

At
December 31, 2008, we had net deferred tax assets of $56.2 million. Valuation allowances were $5.6 million and $6.3 million, as of December 31, 2008 and 2007, respectively. The valuation allowances 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.

On September 12, 2007, we completed the
acquisition of the MCPD business from Intel, paying cash of $31.8 million at closing and estimated direct acquisition-related expenses of $282,000.

During the years ended December 31, 2009, 2008 and 2007, we used $4.8 million, $6.3 million and $5.7 million, respectively, for capital expenditures. During the year ended December 31, 2009
capital expenditures consisted primarily of upgrades to our internal infrastructure, expenditures associated with our transition to a fully outsourced manufacturing model, and the expansion of our Shanghai, China design center. 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.

During the years ended December 31, 2009, 2008 and 2007, we received $4.8 million, $5.2 million and $4.8 million, respectively, in proceeds from the issuance of common stock through our stock compensation plans.

Changes in foreign currency rates impacted beginning cash balances by $92,000, ($301,000), and $353,000 during 2009, 2008 and 2007,
respectively. Due to our 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, 2009 and 2008, working capital was $140.4 million and $66.1 million, respectively. Working capital increased by $74.3 million due primarily to the reclassification of our long-term
investments and our ARS settlement right to short-term during 2009. Working capital was further impacted by an increase in our overall cash balance of $26.7 million, to $100.7 million at December 31, 2009 from $74.0 at December 31, 2008.
The increase in our overall cash balance was driven by cash flows from operations totaling $25.4 million during 2009.

We currently hold investments in auction rate
securities (ARS), the majority of which represent interests in collateralized debt obligations supported by pools of government-backed student loans with S&P AAA or Moodys Aaa ratings at the time of purchase. During the first
quarter of 2008, our portfolio of ARS investments 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. During the fourth quarter of 2008, we accepted a settlement offer
from our investment bank, UBS AG, associated with the failed auctions. Under the terms of the offer, we have the right to require the bank to repurchase at par value our ARS investments at any time between June 30, 2010 and June 30, 2012.
As we plan to require UBS repurchase our ARS on June 30, 2010, these investments have been classified as short-term investments. For our ARS settlement right, we have elected the fair value option for financial assets and financial liabilities.

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

We have a secured revolving line of credit agreement
with Silicon Valley Bank (SVB), dated as of August 7, 2008 (as amended, the Revolving Credit Agreement). The Revolving Credit 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 Revolving Credit Agreement bear interest at the prime rate, which was 3.25% as of December 31, 2009, or the LIBOR rate, which was 0.23% as of
December 31, 2009, plus 1.25%, with either interest rate determined by 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 Revolving Credit Agreement provides sub-facilities for letters of credit and
foreign exchange contracts to be issued on our behalf.

The credit facility 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 quarterly 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 during the term of the agreement. Additionally, any quarterly EBITDA (earnings before interest, taxes, depreciation, amortization, stock based compensation,
goodwill impairment charges, and deferred tax asset valuation charges, as defined in the Agreement) loss may not exceed $3.0 million in any one quarter. For quarterly periods beginning after January 1, 2009, we must maintain a positive rolling
four quarter EBITDA. In addition, capital expenditures may not exceed $8.0 million in any fiscal year.

##### Table of Contents

As of December 31, 2009, we had no outstanding balances on the line of credit or
letters of credit issued on our behalf.

UBS

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 the terms of the offer, UBS AG would issue ARS settlement rights to us, which in addition to the terms discussed in Note 2Cash Equivalents and Investmentsof the Notes to the Consolidated Financial Statements, would
also entitle us to receive no net cost loans from UBS AG, or its affiliates, for up to 75% of the market 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. 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 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 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, 2009, we had an outstanding balance on the Credit Line in the amount of $41.3 million.

2013 Convertible Senior Notes

During February 2008, we 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 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 up 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 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, 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, 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. The strike price of the capped call transaction 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. The capped call transaction provides for net-share settlement in the event that the volume-weighted average price per share of our common stock on the settlement
date exceeds the strike price of approximately $13.03 per share. In such event, the hedge counterparty would deliver

##### Table of Contents

to us a number of shares equal to a formula determined by the quotient resulting from (a) the shares being settled times the difference between the volume-weighted average price on the
settlement date and the strike price of approximately $13.03 per share, divided by (b) the volume-weighted average price on the settlement date. If the volume-weighted average price on the settlement date equals or exceeds the cap price of
$23.085 per share, the difference in (a) would be $23.085 minus $13.03, or $10.055. Because the maximum number of shares deliverable under the capped call transaction is less than the number of shares issuable upon conversion of the 2013
convertible senior notes, we refer to this effect as dilution mitigation. If 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, no additional shares would be delivered under the capped call transaction, and correspondingly, 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. Although the capped call transaction covers approximately 4.2 million shares, in order to facilitate an orderly settlement process, the shares
are divided into tranches of approximately 211,000 shares each, settling on the twenty consecutive trading days prior to the date of maturity of our convertible notes. Thus, on each settlement date, approximately 211,000 shares would be settled,
assuming a volume-weighted average price on such settlement date of $23.085. Assuming volume-weighted average price of $23.085, the hedge counterparty would deliver to us approximately 91,904 shares on each settlement date, calculated as follows:
211,000 x ($23.085  $13.03)/$23.085 = 91,904.

We were advised by the hedge counterparty that, in order to hedge or
manage its risk of having to deliver shares under the capped call transaction, depending on whether our stock price rises or falls, the counterparty may purchase our common stock in the open market or enter into derivative transactions equivalent to
purchasing our stock (in which case its derivative counterparty would be expected to purchase common stock or accomplish the equivalent in derivative transactions) and/or may sell our common stock, enter into derivative transactions equivalent to
selling our stock or unwind (that is, cancel upon payment of agreed consideration) previous derivative transactions (which would be the equivalent of selling our common stock). These types of transactions are commonly referred to as modifying
hedge positions. Such modifications to our counterpartys hedge positions may have an effect on our stock price.

As of December 31, 2009 and 2008, we had outstanding 2013 convertible senior notes with a face value of $50.0 million. As of December 31, 2009 and 2008, the fair value of our 2013 convertible senior notes was
$44.8 million and $26.9 million, respectively.

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.

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 non-performance. 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. Unrealized gain positions
are recorded as other current assets and unrealized loss positions are recorded as other current liabilities. 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. Typically, hedge ineffectiveness could result when the amount
of our hedge contracts exceed our forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures the associated gain (loss) on the contract will remain in other comprehensive income until the
underlying hedged transaction affects net income (loss), at which time the gain (loss) will be recorded to the expense line item being hedged, which is primarily R&D. 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.

obligations are entered into in the ordinary course of business and are expected to be funded by cash flows from continuing operations.

In addition to the above, as discussed in Note 16Income Taxesof the Notes to the Consolidated Financial Statements, we have approximately $2.1 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
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.

##### Table of Contents

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 an 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

At December 31, 2009, our cash, cash equivalents and investments, net, amounted to $155.0 million, of which $54.3 million consisted of ARS at fair value. We believe that our current cash, cash
equivalents and investments, net, the cash generated from operations and our line of credit facilities will satisfy our short and long-term expected working capital needs, capital expenditures, stock repurchases, and other liquidity requirements
associated with our existing business operations. On June 30, 2010 we intend to exercise our right to require UBS to repurchase our ARS investments for total gross proceeds of $62.2 million. The exercise of the settlement right will
require us to pay off our line of credit with UBS, which is anticipated to require us to pay $41.3 million. This reduction in cash will be offset by UBSs payment to us in settlement of our ARS investments and ARS settlement right. We
believe the settlement of our ARS investments and ARS settlement right, offset by the pay off of our UBS line of credit, will result in a net improvement to our cash and cash equivalents of $20.9 million. If we were required to hold our ARS
until maturity, we believe we would still be able to satisfy our short and long-term expected working capital needs, capital expenditures, stock repurchases, other liquidity requirements associated with our existing business operations.

Recent Accounting Pronouncements

See Note 1Significant Accounting Policiesof the Notes 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, 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, 2009 and December 31, 2008 was $70.2 million and $66.2 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 Canadian Dollar, Euro, Chinese Yuan, Japanese Yen, Malaysian Ringgit, British Pound Sterling, and New Shekel. Our 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

##### Table of Contents

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.

Based on our policy, we have established a foreign currency exposure management program which uses derivative foreign exchange contracts to
address nonfunctional currency exposures. In order to reduce the potentially adverse effects of foreign currency exchange rate fluctuations, we have entered into forward exchange contracts. These hedging transactions limit our exposure to changes in
the U.S. Dollar/Canadian Dollar exchange rate, and as of December 31, 2009 the total notional or contractual value of the contracts we held was $11.2 million. These contracts will mature over the next 20 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 require an adjustment of $1.2 million, reversing our hedge asset and creating a hedge liability as of December 31, 2009, in the amount of $407,000. A 10% favorable fluctuation, in relation to our hedge positions, of the
U.S. Dollar relative to the Canadian Dollar would result in an adjustment of $1.2 million and increase our total hedge asset as of December 31, 2009, to $2.0 million. 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. As of December 31, 2009 our hedged positions are associated with our exposure to movements in the Canadian Dollar. If there is an unfavorable movement
in the Canadian Dollar relative to our hedged positions this would be offset by reduced expenses, after conversion to the U.S. Dollar, associated with obligations paid for in the Canadian Dollar.

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 $44.8 million at December 31, 2009.

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.

|(C) | First Quarter 2009 Deferred Tax Valuation Allowance.During the first quarter of 2009, we incurred $42.0 million in charges related to the establishment of a
full valuation allowance against our U.S. net deferred tax assets. We record deferred tax assets to the extent we believes these assets will more likely than not be realized. In making such determination, we considered all available positive and
negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based upon our review of all positive and negative evidence, including our
projected three year U.S. cumulative pre-tax book loss and taxable loss, we concluded that a full valuation allowance should be recorded against our U.S. net deferred tax assets.

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, 2009. 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, 2009, 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, 2009, 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 57 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, 2009, based on criteria established in Internal 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, 2009, 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, 2009 and 2008, 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, 2009, and our report dated March 15, 2010 expressed an unqualified opinion on those consolidated financial statements.

The Board of Directors and Shareholders

RadiSys
Corporation:

We have audited the accompanying consolidated balance sheets of RadiSys Corporation and subsidiaries as of
December 31, 2009 and 2008, 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, 2009.
These 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, 2009 and 2008, and the results of their operations and their cash flows for each of the years in the three year period ended December 31,
2009, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 1 to the consolidated financial
statements, the Company adopted Financial Accounting Standards Board Staff Position 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)
(codified in FASB ASC Topic 470, Debt with Conversions and Other Options) effective as of January 1, 2009 and retrospectively adjusted its accounting for its consolidated financial statements for the years ended December 31, 2008 and 2007
presented herein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), RadiSys Corporations internal control over financial reporting as of December 31, 2009, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of
the Treadway Commission (COSO), and our report dated March 15, 2010 expressed an unqualified opinion on the effectiveness of the Companys internal control over financial reporting.

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 application-ready software and hardware platforms for use in the communications, multi-media, military and aerospace, and medical markets. The Company has evolved into a
leading provider of application-ready software and hardware platforms to original equipment manufacturers (OEM) within the communications networks and commercial systems markets. The Company provides its customers with advanced
infrastructure platforms that enable them to focus their resources and development efforts on their key areas of differentiation, while allowing them to provide higher value systems with a time-to-market advantage at a lower total cost.

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 (GAAP).
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 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 or if support is the only undelivered element, revenue is recognized ratably over the
support term. 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 applicable GAAP for revenue recognition. 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 17.5%, 15.2% and 9.9% for the years ended December 31, 2009, 2008 and 2007. 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 the Companys 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 applicable GAAP for
software revenue recognition.

Software royalties and licenses

Revenue from software royalties and licenses is recognized in accordance with applicable GAAP for software revenue recognition. 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 applicable GAAP for software revenue recognition. 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. 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.

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.



| |  |  | Undelivered elements of an arrangementCertain software sales include specified 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.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Capitalized Software Development Costs

The Company does not capitalize internal software development costs incurred in the production of computer software as the Company 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 research and development (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, 2009, 2008 and 2007 shipping and handling
costs represented approximately 1% of cost of sales.

Advertising Costs

The Company expenses advertising costs as incurred. Advertising costs consist primarily of media, display, and print advertising, along with
trade show costs and product demos and brochures. For 2009, 2008 and 2007 advertising costs were $1.5 million, $1.6 million and $1.3 million, respectively.

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.

Investments

Auction rate securities (ARS) are classified as short-term investments. 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 Balance Sheets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The Company classifies, at the date of acquisition, its investments into categories in
accordance with applicable GAAP for investments in debt and equity securities. The Companys investment policy requires that the held-to-maturity investments, including cash and investments, not exceed a maximum weighted-average maturity of 12
months. In addition, the policy mandates that an individual investment must have a maturity of less than 24 months, with no more than 20% of the total portfolio exceeding 18 months. Realized gains and losses, and interest and dividends on all
securities were included in other income (expense), net in the Consolidated Statements of Operations.

The Companys
current holdings of ARS are classified as trading securities as it plans to exercise its right to require its investment bank to repurchase, at par value, its ARS no later than June 30, 2010 under the terms of a settlement right. Refer to Note
2Cash Equivalents and Investments for further discussion of the terms of the Companys settlement right. Unrealized holding gains and losses from its ARS and ARS settlement right are included in other income (expense) in its
Consolidated Statement of Operations.

The Company determined the fair value of its ARS settlement right based on the
difference between the estimated fair value of the ARS and the par value of the ARS. This difference was then discounted based on the future date when the settlement right is expected to be exercised to account for the time value of money. The
discount rate used took into consideration the risk free rate as well as UBSs credit quality. The Companys valuation of its ARS settlement right is contingent upon the financial viability of its investment bank and accordingly, the
Company has assigned a credit risk component based on market data available at the time of valuation. However, if market conditions change and the Companys investment bank is unable to fulfill its commitment, the realizable value of the
Companys ARS settlement right would be adversely affected. 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.

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. 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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



to the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand and market conditions. Our inventory valuation allowances
establish a new cost basis for inventory.

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. 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 at least annually and also under certain circumstances. During the fourth quarter of 2008, the Company impaired its entire amount of previously recorded goodwill in the amount of $67.3 million. As of December 31, 2009 and 2008,
the Company had no goodwill balances recorded.

Intangible assets with estimable useful lives are amortized over their
respective estimated life and reviewed for impairment whenever events or circumstances require management to do so.

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.



|                                                            |  |                                                   
|----------------------------------------------------------- |  | --------------------------------------------------
|Machinery, equipment, furniture and fixtures                |  | 5 years                                           
|Software, computer hardware and manufacturing test fixtures |  | 3 years                                           
|Engineering demonstration products and samples              |  | 1 year                                            
|Leasehold improvements                                      |  | Lesser of the lease term or estimated useful lives

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

Accounting for Leases

The Company leases all of its facilities, certain office equipment and vehicles under non-cancelable operating leases that
expire at various dates through 2016, 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Asset Retirement Obligations

The Company leases all 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. 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, 2009 and 2008, the Company identified $75,000, of asset retirement obligations, which is included in Other long-term liabilities, net in the accompanying Consolidated Balance Sheets.

Accrued Restructuring and Other Charges

For the years ended December 31, 2009, 2008 and 2007, expenses associated with exit or disposal activities are recognized when probable and estimable because the Company has a history of paying
severance benefits. For leased facilities that were vacated, 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.

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, 2009 and December 31, 2008.

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

Income tax accounting 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 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 after evaluating whether certain the tax positions are more likely than not to be sustained by taxing authorities. In addition, the Company recognizes potential accrued interest and penalties
related to unrecognized tax benefits within its global operations in income tax expense.

Fair Value of Financial Assets and Liabilities

The Company measures at fair value certain financial assets and liabilities, including cash equivalents, short-term investments, its ARS
settlement right, and deferred compensation. GAAP 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.

Comprehensive Income (Loss)

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) for foreign currency translation.

Stock-Based Compensation

Stock-based compensation expense for all stock-based compensation awards is based on the estimated grant-date fair value. The Company uses the Black-Scholes model to measure the grant date fair value of
stock options and ESPP shares. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award. 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 units issued under the 2007 stock plan that are expected to
vest is recognized on a straight-line basis over the requisite service period, which is three years. The estimate of the number of options, ESPP shares and restricted stock units issued under the 2007 stock plan expected to vest is determined based
on historical experience.

The Company computes the grant date fair value of restricted stock units granted under the LTIP and
2007 Stock Plan 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 units, issued under the
LTIP, are expensed ratably over the measurement period of the award. The estimated number of restricted stock units, issued under the LTIP, expected to vest is based upon financial results of the Company as compared to the performance goals set for
the award and is adjusted quarterly.

Net income (loss) per share

Basic earnings per share amounts are computed based on the weighted-average number of common shares outstanding. Diluted earnings per share
amounts incorporate 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 interest expense foregone on the convertible notes.

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s activities expose it to a variety of market risks, including the effects of changes in foreign currency exchange rates.
The Company manages these risks through the use of forward exchange contracts, designated as foreign-currency cash flow hedges, in an attempt to reduce the potentially adverse effects of foreign currency exchange rate fluctuations that occur in the
normal course of business. As such, the Companys hedging activities are all employed solely for risk management purposes. All hedging transactions are conducted with, in the opinion of management, financially stable and reputable financial
institutions.

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. 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. Typically, hedge ineffectiveness could result when the amount of the Companys hedge contracts exceed the Companys forecasted or actual transactions for which the
hedge contracts were designed to hedge. Once a hedge contract matures the associated gain (loss) on the contract will remain in other comprehensive income until the underlying hedged transaction affects net income (loss), at which time the gain
(loss) will be recorded to the expense line item being hedged, which is primarily R&D. The Company only enters into derivative contracts in order to hedge foreign currency exposure. If the Company entered into a contract for speculative reasons
or if the Companys current hedge position becomes ineffective, changes in the fair values of the derivatives would be recognized in earnings in the current period.

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, 2009 and 2008. 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. 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 transaction (loss) gain of $(195,000), $193,000, and $(116,000) for the
years ended December 31, 2009, 2008 and 2007, respectively.

Recent Accounting Pronouncements

Effective July 1, 2009, the Company adopted the Financial Accounting Standards Board (FASB) Accounting Standards
Codification (ASC) 105-10, Generally Accepted Accounting PrinciplesOverall (ASC 105-10). Under ASC 105-10, the FASB Accounting Standards Codification (the Codification) became the exclusive source of
authoritative GAAP recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. The Codification
superseded all then-existing non-SEC accounting and

reporting standards, with the exception of certain non-SEC accounting literature, which became non-authoritative. The adoption of ASC 105-10 did not have an impact on the Companys
consolidated financial statements; however, it changed the way in which the Company discloses information regarding financial assets, liabilities and results of operations.

In March 2008, the FASB issued a new accounting standard on disclosures about derivative instruments and hedging activities, which amended
previous literature to require 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 GAAP, and (iii) how derivative instruments and related hedged items affect an entitys financial position, financial performance, and cash flows. This standard became effective for the Company on January 1, 2009
and the required enhanced disclosures have been provided for in Note 13Hedging.

In May 2008, the FASB
issued a new accounting standard on accounting for convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement). Under the Codification, this standard is located in the cash conversion subsections of
ASC 470-20, Debt with Conversion and Other Options. This standard required that issuers of such instruments separately account for the liability and equity components related to convertible debt instruments in a manner that reflects the
issuers nonconvertible debt borrowing rate when interest expense is recognized in subsequent periods. This standard became effective for the Company on January 1, 2009. Based on its analysis, the Company determined that the new guidance
only affected its 1.375% convertible senior notes which were due November 15, 2023 (the 2023 convertible senior notes), even though the notes were retired during the fourth quarter of 2008. Accordingly, the Company is required to
retrospectively apply this guidance to all periods presented that include the 2023 convertible senior notes. As a result of this retrospective application, the Company adjusted its opening accumulated deficit balance and paid in capital
balances as of December 31, 2006.

In September 2009, the FASB issued Update No. 2009-13, Multiple-Deliverable
Revenue Arrangementsa consensus of the FASB Emerging Issues Task Force (ASU 2009-13). ASU 2009-13 updates the existing multiple-element revenue arrangements guidance currently included under ASC 605-25, which originated primarily from
the guidance in EITF Issue No. 00-21, Revenue Arrangements with Multiple Deliverables (EITF 00-21). The revised guidance amends ASC subtopic 650-25 to eliminate the requirement that all undelivered elements have either vendor-specific
objective evidence (VSOE) or third-party evidence (TPE) prior to recognition of a portion of the arrangement fee that is attributable to items that have already been delivered. In the absence of VSOE or TPE of the standalone
selling price for one or more delivered or undelivered elements in a multiple-element arrangement, entities will be required to estimate the selling prices of those elements. Accordingly, the overall arrangement fee will be allocated based on their
relative selling prices. ASU 2009-13 also eliminates the residual method to allocate the arrangement consideration. In addition, the guidance also expands the disclosure requirements for revenue recognition. ASU 2009-13 will be effective for the
first annual reporting period beginning on or after June 15, 2010, with early adoption permitted provided that the revised guidance is retroactively applied to the beginning of the year of adoption. The Company has elected to adopt the
provisions of ASU 2009-13 as of January 1, 2010, however it is currently assessing the future impact of this new accounting update to its consolidated financial statements.

In October 2009, the FASB issued ASU 2009-14, Certain Arrangements That Include Software Elements, (amendments to FASB ASC Topic
985, Software) (ASU 2009-14). ASU 2009-14 amends the original authoritative literature currently under ASC 985-605, and originally issued under AICPA Statement of Position 97-2, Software Revenue Recognition,and its
related interpretive guidance. The original guidance applies to revenue arrangements for products or services that include software that is more-than-incidental to the products as a whole. The amendment under ASU 2009-14, excludes from
its scope tangible products that contain both

software and non-software components that function together to deliver a products essential functionality. ASU 2009-14 will be effective for the first annual reporting period beginning on
or after June 15, 2010, with early adoption permitted provided that the revised guidance is retroactively applied to the beginning of the year of adoption. The Company has elected to adopt the provisions of ASU 2009-13 as of January 1,
2010, however it is currently assessing the future impact of this new accounting update to its consolidated financial statements.

The Company
currently holds investments in auction rate securities (ARS), the majority of which represent interests in collateralized debt obligations supported by pools of government-backed student loans with S&P AAA or Moodys Aaa ratings
at the time of purchase. During the first quarter of 2008, the Companys 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. During the fourth quarter of
2008, the Company accepted a settlement offer from its investment bank, UBS AG, associated with the failed auctions. Under the terms of the offer, the Company has the right to require the bank to repurchase at par value its ARS investments at any
time between June 30, 2010 and June 30, 2012. As the Company plans to require UBS to repurchase its ARS on June 30, 2010, these investments have been classified as short-term investments. For its ARS settlement right, the Company has
elected the fair value option for financial assets and financial liabilities. Management elected the fair value option for the ARS settlement right in order to quantify its agreement with UBS, as it guarantees settlement at par value, which
essentially offsets any impairment on its ARS.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The Company records its ARS and corresponding settlement right at fair value, using the
income approach, in accordance with the applicable GAAP using level 3 inputs, as defined in Note 3Fair Value of Financial Instruments. The Company considered various inputs to estimate the fair value of its ARS at December 31,
2009, including the estimated time believed to allow the market for such investments to recover, projected estimates of future risk-free rates, as well as premiums designed to account for liquidity and credit risks associated with its ARS holdings.

The Company determined the fair value of its ARS settlement right based on the difference between the estimated fair value of
the ARS and the par value of the ARS. This difference was then discounted based on the future date when the settlement right is expected to be exercised to account for the time value of money. The discount rate used took into consideration the risk
free rate as well as UBSs credit quality. The Companys valuation of its ARS settlement right is contingent upon the financial viability of its investment bank and accordingly, the Company has assigned a credit risk component based on
market data available at the time of valuation. However, if market conditions change and the Companys investment bank is unable to fulfill its commitment, the realizable value of the Companys ARS settlement right would be adversely
affected.

Note 3Fair Value of Financial Instruments

The Company measures at fair value certain financial assets and liabilities, including cash equivalents, short-term investments, its ARS
settlement right, and deferred compensation. GAAP 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, 2009, for the Companys financial instruments, including its ARS (in thousands):

ARS and ARS settlement right. Unrealized gains on the Companys ARS, which totaled $3.7 million for the year ended December 31, 2009, are included in other income in the Companys Consolidated Statement of Operations. Valuation of the
Companys ARS settlement right is performed using a present value approach on the difference between the estimated fair value and the par value of the ARS investments. Therefore, there is an inverse relationship between changes in the value of
the Companys ARS investments and its settlement right. Unrealized losses on the Companys ARS settlement right for the year ended December 31, 2009, which totaled $3.2 million, are included in other income in the Companys
Consolidated Statement of Operations.

|(A) | The Company is contractually obligated to reimburse its contract manufacturer for the cost of excess inventory purchased based on the Companys forecasted demand
when there is no alternative use. The Companys inventory deposit represents a cash deposit paid to its contract manufacturers for excess and obsolete inventory. The deposit is recorded net of adverse purchase commitment liabilities, and
therefore the net balance of the deposit represents inventory the Company believes will be utilized. The deposit will be applied against future adverse purchase commitments owed to the Companys contract manufacturers or reduced based on the
usage of inventory. See Note 14Commitments and Contingencies for additional information regarding the Companys adverse purchase commitment liability.

Consigned inventory is held at third-party locations, including the Companys contract manufacturing partners and customers. The
Company retains title to the inventory until purchased by the third-party. Consigned inventory, consisting of raw materials and finished goods, was $3.0 million and $2.3 million at December 31, 2009 and 2008, respectively.

Intangible assets amortization expense was $9.1
million, $19.0 million and $19.4 million for the years ended December 31, 2009, 2008 and 2007, respectively. The Companys purchased intangible assets have lives ranging from one to 10 years. 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.

During 2008, 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. 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. 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 intangible assets of its Canadian subsidiary 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 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

reduction in our amortization expense of $1.7 million. The impact of the change in estimate resulted in a pre-tax decrease to net loss of $1.7 million, and a pre-tax decrease in fully diluted
loss per share of $0.08.

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 completed this
office closure during the first quarter of 2009.

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 completed all activities associated with the restructuring during the first quarter of 2009.

First Quarter 2009 Restructuring

During the first quarter of 2009,
the Company initiated a restructuring plan that included the elimination of 29 positions. The restructuring was initiated to align the Companys costs with its annual operating plan. During 2009 the Company incurred a total of $1.5 million in
restructuring charges, which were comprised almost entirely of employee payroll related severance costs. Included in these costs were charges related to the modification of equity awards to certain employees included in this restructuring activity.
The Company expects all activities associated with this restructuring to be completed by first quarter of 2010.

Second Quarter 2009 Restructuring.

During the second quarter of 2009, the Company initiated a restructuring plan that includes the elimination of 115 positions and the
relocation of eight employees as part of two strategic initiatives within manufacturing operations and engineering. As part of the initiative, the Company plans to transition to a fully outsourced manufacturing model, which will transfer remaining
manufacturing from its manufacturing plant in Hillsboro, Oregon to its manufacturing partners in Asia. The plan also includes consolidating the Companys North American research and development positions and programs, and specifically
transferring current projects from its design center in Boca Raton, Florida, to other existing R&D centers. During 2009, the Company incurred a total of $3.1 million in restructuring charges, which consisted of accrued severance obligations,
healthcare benefits, relocation incentives and related payroll taxes. The balance also includes legal expenditures as well as contract termination fees. The Company currently expects to incur approximately $200,000 in additional restructuring
charges over the next 4 months associated with the second quarter 2009 restructuring plan. These additional charges are primarily related to employee relocation costs. This transition is expected to be substantially complete by the third quarter of
2010.

Note 11Short-Term Borrowings

Silicon Valley Bank

The Company has a secured revolving line of credit agreement with Silicon Valley Bank, which 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. During 2009, the Company extended the term of the agreement for another year, which will now end on September 30, 2011. Borrowings under the agreement bear interest at the prime rate, which
was 3.25% as of December 31, 2009, or the LIBOR rate, which was 0.23% as of December 31, 2009, 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 quarterly 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 during the term of the agreement. Additionally, any quarterly EBITDA (earnings before interest, taxes, depreciation, amortization, stock based compensation, goodwill impairment charges, and deferred tax asset
valuation charges, as defined in the Agreement) loss may not exceed $3.0 million in any one quarter. 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 $8.0 million in any fiscal year.

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. Under the terms of the offer, UBS AG would issue ARS settlement rights to the Company, which in addition to the terms discussed in Note 2Cash Equivalents and Investments, would also entitle the
Company 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. 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 ARS and is currently set at T-Bill plus 1.20%, which will be subject to 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, 2009 and 2008, the Company had outstanding balances on the Credit Line in the amount of $41.3 million $39.5 million,
respectively.

Note 12Convertible Debt

2013 Convertible Senior Notes

During February 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 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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. The strike price of the capped call transaction
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. The capped call transaction provides for net-share settlement in the event that the
volume-weighted average price per share of the Companys common stock on the settlement date exceeds the strike price of approximately $13.03 per share. In such event, the hedge counterparty would deliver to the Company a number of shares equal
to a formula determined by the quotient resulting from (a) the shares being settled times the difference between the volume-weighted average price on the settlement date and the strike price of approximately $13.03 per share, divided by
(b) the volume-weighted average price on the settlement date. If the volume-weighted average price on the settlement date equals or exceeds the cap price of $23.085 per share, the difference in (a) would be $23.085 minus $13.03, or
$10.055. If 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. Although the capped call transaction
covers approximately 4.2 million shares, in order to facilitate an orderly settlement process, the shares are divided into tranches of approximately 211,000 shares each, settling on the twenty consecutive trading days prior to the date of
maturity of the Companys convertible notes. Thus, on each settlement date, approximately 211,000 shares would be settled, assuming a volume-weighted average price on such settlement date of $23.085. Assuming a volume-weighted average price of
$23.085, the hedge counterparty would deliver to the Company approximately 91,904 shares on each settlement date, calculated as follows: 211,000 x ($23.085  $13.03)/$23.085 = 91,904.

During the fourth quarter of 2008, the Company repurchased $5.0 million aggregate principal amount of the 2013 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.

For the years ended December 31, 2009 and 2008, the effective interest rate for the 2013 convertible senior notes was approximately
3.6% and 2.6%, respectively. During the years ended December 31, 2009 and 2008, the Company incurred contractually stated interest costs totaling $1.4 million and $1.3 million, respectively. During the years ended December 31, 2009 and
2008, the Company incurred costs related to the amortization of issuance costs totaling $447,000 and $659,000, respectively.

As of December 31, 2009 and December 31, 2008, the Company had outstanding 2013 convertible senior notes with a face value of $50.0 million. As of December 31, 2009 and December 31, 2008, the fair value of the
Companys 2013 convertible senior notes was $44.8 million and $26.9 million, respectively.

2023 Convertible Senior
Notes

During the first quarter of 2009, the Company adopted the cash conversion subsections of ASC Topic 470-20. ASC
Topic 470-20 is effective for the Companys previously outstanding 1.375% convertible senior notes due 2023. Although, the Companys 2023 convertible senior notes were retired as of December 31, 2008, the Company was still required to
retrospectively apply Cash Conversion Subsections in all periods presented that include the Companys 2023 convertible senior notes. As a result of this retrospective application, the Companys opening accumulated deficit and additional
paid in capital balances were adjusted by ($9.6 million) and $16.2 million, net of tax, respectively.

The Cash Conversion Subsections required that issuers of convertible instruments that
may be settled in cash upon conversion separately account for the liability and equity components related to convertible debt instruments in a manner which would reflect the issuers nonconvertible debt borrowing rate when interest expense is
recognized in subsequent periods. As such, the Company calculated the liability component, at issuance, to be $73.6 million. The liability component was calculated as the present value of cash lows from the related principal and interest payments
using an 8.0% discount rate. The discount rate used represented the Companys estimated borrowing rate, at the date of issuance, for a similar debt instrument without the conversion feature. The equity component, recorded as additional paid-in
capital, totaled $16.2 million, which represented the difference between the proceeds from the issuance of the notes and the fair value of the liability, net of deferred taxes and equity related issuance costs of $10.2 million, as of the date of the
issuance.

The Cash Conversion Subsections also requires an accretion of the resultant debt discount over the expected life of
the notes, which was November 15, 2003 to November 15, 2008. Accordingly, the Consolidated Statements of Operations for the years ended December 31, 2008 and 2007, were retrospectively modified, compared to previously reported
amounts, as follows (in thousands, except per share amounts):

For the years ended December 31, 2008 and 2007, the effective interest rate for the liability component
of the notes was approximately 6.0% and 7.8%, respectively. During the years ended December 31, 2008 and 2007, the Company incurred contractually stated interest costs totaling $619,000 and $1.4 million. During the years ended December 31,
2008 and 2007, the Company incurred interest costs of $5.4 million and $5.7 million, respectively, related to amortization of the discount on the liability component of the notes.

Note 13Hedging

The Companys activities expose it to a variety
of market risks, including the effects of changes in foreign currency exchange rates. The Company manages these risks through the use of forward exchange contracts, designated as foreign-currency cash flow hedges, in an attempt to reduce the
potentially adverse effects of foreign currency exchange rate fluctuations that occur in the normal course of business. As such, the Companys hedging activities are all employed solely for risk management purposes. All hedging transactions are
conducted with, in the opinion of management, financially stable and reputable financial institutions. As of December 31, 2009 and 2008, and for the years ended December 31, 2009 and 2008, the only hedge instruments executed by the Company
are associated with its exposure to fluctuations in the Canadian Dollar which result from obligations such as payroll and rent paid in Canadian Dollars.

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. 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. Typically, hedge ineffectiveness could result when the amount of the Companys hedge
contracts exceed the Companys forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures the associated gain (loss) on the contract will remain in other comprehensive income until the
underlying hedged transaction affects net income (loss), at which time the gain (loss) will be recorded to the expense line item being hedged, which is primarily R&D. The Company only enters into derivative contracts in order to hedge foreign
currency exposure. If the Company entered into a contract for speculative reasons or if the Companys current hedge position becomes ineffective, changes in the fair values of the derivatives would be recognized in earnings in the current
period.

The Company assesses, 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 years ended December 31, 2009 and
2008, the Company had no hedge ineffectiveness.

During the year ended December 31, 2009, the Company entered into
fifty-six new foreign currency forward contracts, with total contractual values of $11.8 million. During the year ended December 31, 2008, the Company entered into twenty-three new foreign currency forward contracts, with total contractual
values of $14.5 million.

fair values of derivative financial instruments designated as cash flow hedges at December 31, 2009 is as follows (in thousands):

Over the
next twelve months, the Company expects to reclassify into earnings a gain of approximately $787,000, currently recorded as other comprehensive income, as a result of the maturity of currently held forward exchange contracts.

The bank counterparties in these contracts expose the Company to credit-related losses in the event of their nonperformance. However, to
mitigate that risk, the Company only contracts with counterparties who meet its minimum requirements regarding counterparty credit worthiness. In addition, the Company monitors credit ratings, credit spreads and potential downgrades prior to
entering into any new hedging contracts.

Rent expense totaled $5.2 million, $5.4 million and
$5.7 million for the years ended December 31, 2009, 2008 and 2007, respectively.

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 10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, 2009.

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.

The following is a summary of the change in the Companys warranty accrual reserve (in thousands):

At December 31, 2009, our unrecognized tax benefits associated with uncertain tax positions were $2.1
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, 2009, the Company recognized a net increase of
approximately $16,000 for a total of $694,000 in potential interest and penalties associated with uncertain tax positions.

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 are closed for all federal and state income tax years before 2006 and 2005, respectively. The statute of limitations for the Companys Canadian subsidiary are closed for all
tax years ended before August 31, 2006. The statute of limitations for the Companys other foreign subsidiaries are closed for all income tax years before 2000 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. It is
reasonably possible that the Companys uncertain tax positions could decrease by $2.6 million including interest and penalties of $441,000 and $253,000, respectively, in the next twelve months.

The Company is currently under Internal Revenue Service (IRS) examination. In the fourth quarter of 2009, the IRS commenced its
examination of the 2007 and 2008 years. Subsequent to December 31, 2009, the IRS has issued and the Company has agreed to a Notice of Proposed Adjustment. The Proposed Adjustment was provided in full as an uncertain tax position at
December 31, 2009. The Company is also currently under examination in Canada. The tax periods under examination by the Canada Revenue Agency include fiscal years 2006 through 2008. To date, no proposed adjustment has been made by the Canada
Revenue Agency and the Company believes that it has adequately provided for uncertain tax positions. However, should the Company experience an unfavorable outcome, it could have a material impact on its results of operations, financial position, or
cash flow. The Company is not currently under examination in any other states or foreign jurisdictions.

The Company has
recorded valuation allowances of $48.4 million and $5.6 million, as of December 31, 2009 and 2008, respectively. The $48.4 million valuation allowance at December 31, 2009 represents a full valuation allowance against the Companys
U.S. net deferred tax assets. The $5.6 million valuation allowance at December 31, 2008 was related primarily to U.S. net operating loss and tax credit carryforwards. In evaluating its valuation allowance, the Company considers all available
positive and negative evidence, including scheduled

reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based on the Companys review of all positive and negative
evidence, including a three year U.S. cumulative pre-tax loss it concluded that a full valuation allowance should be recorded against its U.S. net deferred tax assets.

At December 31, 2009 and 2008, the Company had total available federal net operating loss carryforwards of approximately $35.6 million and $27.9 million, respectively. The federal net operating loss
carryforwards expire between 2010 and 2029 and consist of approximately $22.3 million of consolidated taxable loss remaining after loss carrybacks to prior years, $4.5 million of loss carryforwards from the Texas Micro merger in 1999, and $8.8
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 $42.8 million and $40.2 million at December 31, 2009 and 2008, respectively.
The state net operating loss carryforwards expire between 2010 and 2029. The Company also had net operating loss carryforwards of approximately $1.8 million from certain non-U.S. jurisdictions. The non-U.S. net operating loss carryforwards are
attributable to Canada and the United Kingdom (U.K.) The Canada tax losses are attributable to the Convedia acquisition in September of 2006 and they expire in 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 $14.4 million at December 31, 2009, to reduce future income tax liabilities. The federal and state tax credits expire between 2010 and 2029. 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. The Companys Canadian subsidiary also had approximately
$5.8 million in investment tax credit, $12.3 million in unclaimed scientific research and experimental expenditures and $16.2 million in undepreciated capital cost to be carried forward and applied against future income in Canada.

Realization of the foreign 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, 2009. 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.

The Company repatriated $40.1 million from its foreign subsidiaries during 2009. The repatriation resulted in a taxable
dividend of $8.9 million. The remainder of the repatriation was a return of capital and, therefore, was not subject to U.S. income taxes. The Company plans to indefinitely reinvest the remaining earnings of all its foreign subsidiaries. Should the
Company plan to repatriate any foreign earnings in the future, it will be required to establish an income tax liability and recognize additional income tax expense related to such earnings. The Company has indefinitely reinvested approximately $10.5
million of the undistributed earnings of certain foreign subsidiaries at December 31, 2009. Such earnings would be subject to U.S. taxation if repatriated to the United States.

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 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 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 Company granted the first award to
participants under the LTIP on October 1, 2009. The target performance goal for these awards is non-GAAP earnings per share of $0.75. Non-GAAP earnings per share is measured as the cumulative sum over four consecutive quarters during the first
performance period of October 1, 2009 to September 30, 2012 with a first goal achievement date of September 30, 2010 and subsequent goal achievement dates for each calendar quarter thereafter. Quarterly non-GAAP earnings equals
earnings (as calculated in accordance with GAAP) plus stock-based compensation expense, plus amortization of intangible assets, plus or minus restructuring charges or reversals, plus or minus such other items determined as non-recurring or adjusted
from non-GAAP earnings as reported by the Company and as approved by the Committee, plus other adjustments resulting from purchase accounting as determined by the Committee, plus a fixed 20% effective tax rate notwithstanding the tax rate otherwise
applicable in accordance with GAAP. Non-GAAP earnings per share targets range from $0.65 to $0.85 with payouts ranging from 75% to 125% of the target payout amounts. In the aggregate, the target payout amount for the first performance period equals
684,900 shares, or approximately one-third of the total number of shares authorized under the LTIP. Shares cliff-vest upon achievement of the performance goal and if the performance target is not met by the last measurement period, awards will
expire unvested. If a portion of a participants award has been settled on a prior payout determination date upon achievement of a performance goal with respect to a quarter during the performance period, the previously settled portion of such
participants award shall be taken into account and shall be offset against any subsequently settled portion of such participants award on any subsequent payout determination date.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Restricted stock units issued under the LTIP are valued at the closing price of our
common stock on the grant date which was $8.18 on October 1, 2009. The corresponding compensation cost of each LTIP award is expensed ratably over the measurement period of the award. Since the number of shares that may be issued under the LTIP
and the service period are both variable, the Company reevaluates the LTIP awards on a quarterly basis and adjust the number of shares expected to be awarded based upon financial results of the Company as compared to the performance goals set for
the award. Adjustments to the number of shares awarded, and to the corresponding compensation expense, are made on a cumulative basis at the date of adjustment based upon the estimated probable number of shares to be awarded. Adjustments made to
compensation expense resulting from a change in the estimated probable vesting date of the awards are made on a prospective basis. For the year ended December 31, 2009 the Company recorded $452,000 in stock compensation expense associated with
LTIP awards.

In November 2009, the Company completed a stock option exchange program. The Companys eligible employees
were permitted to exchange some or all of their outstanding options, with an exercise price greater than $9.44 per share (which is equal to the 52-week high closing price of our common stock as of the start of this offer), that were granted on or
before October 5, 2008, whether vested or unvested, for restricted stock units, except for employees in Canada who received new stock options with new vesting schedules and exercise prices. All employees of RadiSys and its subsidiaries,
other than members of our Board of Directors, executive officers and employees located in the Netherlands and Israel were eligible to participate in the exchange offer. The option exchange took place on November 3, 2009. Pursuant to the option
exchange 848,800 eligible options were canceled and replaced with 169,600 restricted stock units and 35,000 stock options. The new restricted stock units and stock options have a new three year vesting period that began on November 3, 2009. The
exchange resulted in $173,000 in additional stock compensation expense which will be recognized over the new three year vesting period.

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, 2009 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, 2009. 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, 2009, 2008 and 2007 was $206,000,
$591,000 and $227,000, respectively.

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. An additional
500,000 shares were authorized for the plan in 2009, which brings the total to 5.7 million shares of common stock under the plan. For the years ended December 31, 2009, 2008 and 2007 the Company issued 660,000, 596,000 and 405,000 shares
under the plan, respectively. At December 31, 2009, 1.1 million shares were available for issuance under the plan.

During the second quarter of 2009, the Board of Directors approved an amendment to the
Companys ESPP plan to provide for a one-year holding period with respect to common stock shares purchased by participants under the 1996 plan. The one-year holding period took effect during the fourth quarter of 2009. Due to the
holding period, the Company applies a discount to the ESPP stock compensation to reflect the decreased liquidity. The Company utilizes the Finnerty Asian Put Option Approach to estimate the discount. Inputs for the model include the length
of the holding period, volatility and risk-free rate. The discount applied in the fourth quarter of 2009 was 21.0%.

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

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, 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 Company computes the grant date fair value of restricted stock units granted under the 2007 stock plan and LTIP 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 units granted under the 2007 stock plan that are expected to vest is recognized on a straight-line
basis over the requisite service period, which is three years. The estimate of the number of options, ESPP shares and restricted stock units granted under the 2007 stock plan expected to vest is determined based on historical experience.

The grant date fair value of restricted stock units issued under the Companys LTIP that are expected to vest is recognized ratably
over the service period of the award. The service period of restricted stock units issued under the Companys LTIP is equal to the period of time over which performance objectives underlying the awards underlying objectives are expected to be
achieved. The estimated number of restricted stock units under the Companys LTIP expected to vest is determined based upon financial results of the Company as compared to the performance goals set for the award and is adjusted quarterly.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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.

The Company computed the value of options granted and ESPP shares
issued during 2009, 2008 and 2007 using the Black-Scholes option pricing model. The fair value of the following stock-based awards was estimated using the Black-Scholes model with the following weighted-average assumptions for the fiscal years ended
December 31:

For the
years ended December 31, 2009, 2008 and 2007, the total value of the options granted was approximately $3.5 million, $2.2 million and $3.7 million, respectively. For the years ended December 31, 2009, 2008 and 2007 the weighted-average
valuation per option granted was $3.96, $3.67 and $5.63, respectively. The total estimated value associated with ESPP shares to be granted under enrollment periods beginning in the years ended December 31, 2009, 2008 and 2007 was $164,000,
$563,000 and $449,000, respectively.

restricted stock units is expected to be recognized over a weighted-average period of 1.81 years.

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 $1.1 million, $1.0 million and $905,000 in 2009, 2008 and 2007, 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

The Company has 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 8Other Assets) Deferred amounts may be withdrawn by the participant in case of financial hardship as defined in the plan agreement.

Cash Incentive Program

On September 30, 2009, the Committee put in place a cash incentive program (the Incentive Program) for certain of the
Companys employees to drive breakthrough Company transformations in an accelerated timeframe. The Incentive Program is intended to motivate and recognize the employees performance in achieving the Companys defined strategy and
goals by aligning measurable results with rewards. The Incentive Program is designed to reward the Companys employees who are leading or significantly contributing to the transformational business initiatives in the engineering and operations
organizations.

Awards under the Incentive Program will be based on Company performance as measured by two sets of goals: an
operations outsourcing performance goal and an engineering enterprise performance goal. The performance period for the Incentive Program runs from October 1, 2009 to June 30, 2010. Actual payouts under the Incentive Program will range from
75% to 125% of the target incentive amounts based on the weighted average of achievement of both performance goals. The target incentive amounts account for 50% or less than the existing annual incentive compensation targets. The Incentive
Programs target payout will be approximately $1.0 million.

Note 18Segment Information

The Company is one operating segment. This is because results of operations are provided and analyzed at a company-wide level. Key resources,
decisions, and assessment of performance are also analyzed on a company-wide level. This is the way management organizes the Company for making operating decisions and assessing financial performance by the chief operating decision maker.
