RADISYS CORPORATION

PROXY STATEMENT

SOLICITATION AND REVOCABILITY OF PROXY

This proxy statement is furnished in connection with the solicitation of proxies by the Board of Directors of RadiSys Corporation, an Oregon corporation (“we,” “us”, “RadiSys”, or the “Company”), to be voted at the annual meeting of shareholders to be held at our headquarters located at 5445 NE Dawson Creek Drive, Hillsboro, Oregon 97124, on August 17, 2010 at 8:30 a.m., Pacific time, for the purposes set forth in the accompanying notice of annual meeting. All proxies in the enclosed form that are properly executed and received by us before or at the annual meeting and not revoked will be voted at the annual meeting or any adjournments in accordance with the instructions on the proxy. Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before it is voted. Proxies may be revoked by (i) filing with our Corporate Secretary, at or before the taking of the vote at the annual meeting, a written notice of revocation bearing a later date than the date of the proxy, (ii) duly executing a subsequent proxy relating to the same shares and delivering it to our Corporate Secretary before the annual meeting or (iii) attending the annual meeting and voting in person (although attendance at the annual meeting will not in and of itself constitute a revocation of a proxy). Any written notice revoking a proxy should be sent to RadiSys Corporation, 5445 NE Dawson Creek Drive, Hillsboro, Oregon 97124, Attention: Corporate Secretary, or hand delivered to the Corporate Secretary at or before the taking of the vote at the annual meeting.

The mailing address of our principal executive offices is 5445 NE Dawson Creek Drive, Hillsboro, Oregon 97124.

Pursuant to the rules adopted by the Securities and Exchange Commission (“SEC”) in 2007, we have elected to provide access to our proxy materials over the Internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials (the “Notice”) to our shareholders of record and beneficial owners on or about July 6, 2010, and the proxy statement, the proxy card and the annual report to shareholders are being first given to shareholders on the same date. All shareholders will have the ability to access the proxy materials on a website referred to in the Notice or request to receive a printed set of all the proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice. In addition, shareholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. Choosing to receive your future proxy materials by email will save us the cost of printing and mailing documents and will reduce the impact of our annual shareholder meeting on the environment.

The cost of preparing, printing and mailing this proxy statement and of the solicitation of proxies will be borne by us. Solicitation will be made by mail and, in addition, may be made by our directors, officers and employees personally or by written communication, telephone, facsimile or other means. We may request banks, brokers, fiduciaries and other persons holding shares in their names, or in the names of their nominees, to forward this proxy statement and other proxy materials to the beneficial owners and obtain voting instructions for the execution and return of the proxies. We will reimburse such banks, brokers and fiduciaries for their reasonable out-of-pocket expenses in connection with the proxy solicitation. We have retained Mellon Investor Solutions LLC to aid in the solicitation of proxies for a fee of approximately $9,500, plus reasonable costs and expenses.

For purposes of conducting the annual meeting, the holders of at least a majority of the shares of common stock issued and outstanding and entitled to vote at the annual meeting will constitute a quorum. Directors will be elected by a plurality of the votes of the shares present in person or represented by proxy at the annual meeting and entitled to vote on the election of directors. In a plurality voting, the nominee who receives the most votes for his or her election is elected. Each other proposal requires the approval of a majority of the votes cast on the proposal, provided a quorum is present.

1

If a broker holds your shares, the Notice and, if requested, this proxy statement and a proxy card have been sent to the broker. You may have received this proxy statement directly from your broker, together with instructions as to how to direct the broker to vote your shares. If you desire to have your vote counted, it is important that you return your voting instructions to your broker. A broker non-vote occurs when a broker submits a proxy card with respect to shares of common stock held in a fiduciary capacity (typically referred to as being held in “street name”), but declines to vote on a particular matter because the broker has not received voting instructions from the beneficial owner. Under the rules that govern brokers who are voting with respect to shares held in street name, brokers have the discretion to vote such shares on routine matters, but not on non-routine matters, if the broker has not been furnished with voting instructions by its client at least ten days before the meeting. Routine matters include the ratification of the appointment of auditors. Non-routine matters include the matters being submitted to the shareholders in Proposals 1, 3, and 4. Abstentions and broker non-votes are counted for purposes of determining whether a quorum exists at the annual meeting, but have no effect on the determination of whether a plurality exists with respect to a given nominee in directors’ elections. With respect to other proposals, abstentions will count as votes cast on proposals other than the election of directors, but will not count as votes cast in favor of the proposal and, therefore, will have the same effect as votes against the proposal. Broker non-votes will not be considered to have voted on the proposal and therefore, will have no effect. The proxies will be voted for or against the proposals or as an abstention, in accordance with the instructions specified on the proxy form. If no instructions are given, proxies will be voted for each of the proposals.

The record date for determination of shareholders entitled to receive notice of and to vote at the annual meeting is June 21, 2010. At the close of business on June 21, 2010, 24,169,712 shares of our common stock were outstanding and entitled to vote at the annual meeting. Each share of common stock is entitled to one vote with respect to each matter to be voted on at the annual meeting. We reserve the right to decide, in our discretion, to withdraw any of the proposals from the agenda of the annual meeting prior to any vote thereon.

PROPOSAL 1: TO ELECT EIGHT DIRECTORS

Our Board of Directors currently consists of eight members. The directors are elected at the annual meeting of shareholders to serve until the next annual meeting and until their successors are elected and qualified. Proxies received from shareholders, unless directed otherwise, will be voted FOR the election of the following nominees: C. Scott Gibson, Scott C. Grout, Ken J. Bradley, Richard J. Faubert, Dr. William W. Lattin, Kevin C. Melia, Carl W. Neun, and Lorene K. Steffes.

All of the nominees are currently our directors. We are not aware that any nominee is or will be unable to stand for reelection. If any nominee is not available as a candidate for director, the number of directors constituting our Board of Directors may be reduced before the annual meeting or the proxies may be voted for any other candidate or candidates that are nominated by the Board of Directors, in accordance with the authority conferred in the proxy.

Set forth in the table below is the name, age and position with the Company of each of the nominees. Additional information about each of the nominees is provided below the table and in “Security Ownership of Certain Beneficial Owners and Management.” There are no family relationships among our directors and executive officers.

C. Scott Gibson has served as a Director since June 1993 and as Chairman of our Board of Directors since October 2002. From January 1983 through February 1992, Mr. Gibson co-founded and served as President of Sequent Computer Systems, Inc., a computer systems company. Before co-founding Sequent, Mr. Gibson served as General Manager, Memory Components Operation, at Intel Corporation.

Mr. Gibson serves on the boards of several other companies and non-profit organizations, including Verigy, Triquint Semiconductor, Inc., Pixelworks, Inc., NW Natural, the Oregon Community Foundation and the Franklin W. Olin College of Engineering. During the past five years, Mr. Gibson was previously a director of Electroglas, Inc.

Mr. Gibson holds a B.S.E.E. and a M.B.A. from the University of Illinois.

We believe that Mr. Gibson’s qualifications to serve as a Director include his extensive experience in the semiconductor and computer systems industries, including co-founding and helping take public a highly successful computer systems company. In addition, his service on boards of other high technology companies, including as a member of audit and compensation committees, gives him financial expertise and understanding of compensation policies as well as extensive organizational leadership skills to assist the CEO with strategic planning.

Mr. Grout received a B.S. in Engineering from the University of Wisconsin at Madison and a M.B.A. from the Sloan School of Management at the Massachusetts Institute of Technology.

We believe that Mr. Grout’s qualifications to serve as a Director include his years of executive experience with high technology companies, including his positions as an executive with Chorum Technologies, Inc. and Lucent Technologies, as well as the deep understanding of our people and our products that he has acquired as our Chief Executive Officer.

Mr. Bradley also serves on the Board of Directors of SynQor, Inc., Powerwave Technologies, Inc, and Lytica Inc. Mr. Bradley has a degree in electronics from Algonquin College and in electrical engineering through the Professional Engineers of Ontario.

We believe that Mr. Bradley’s qualifications to serve as a Director include his extensive experience of over 37 years as a manager, executive, consultant and director of global technology companies, including his experience with supply chain management in the Asia-Pacific region. In addition, his service as a director of a variety of other technology companies gives him a deep understanding of the role of the Board of Directors in corporate strategy development.

We believe that Mr. Faubert’s qualifications to serve as a Director include his 38 years of experience as a manager, executive and director of high technology companies, including his experience in leading complex technology enterprises and his experience as the Chief Executive Officer of a semiconductor company. This experience gives Mr. Faubert a deep understanding of best practices in managing complex, high technology businesses from customer requirements through R&D programs.

Dr. William W. Lattin has served as a Director since November 2002. In October 1999, Dr. Lattin retired from Synopsys, Inc., a supplier of electronic design automation software, where he had been an Executive Vice President since October 1994.

Dr. Lattin holds a Ph.D. in electrical engineering from Arizona State University and a M.S.E.E. and a B.S.E.E. from the University of California-Berkeley.

We believe that Mr. Lattin’s qualifications to serve as a Director include his experience of over 34 years as a manager, executive and director of global technology companies, including Intel and Synopsys. His direct experience with embedded systems design, manufacturing sales and marketing enhances the Board’s ability to provide oversight and guidance to our senior executives. His previous experience on boards of other companies within our industry further augment his range of knowledge, providing experience on which he can draw while serving as a member of our Board.

Pursuant to and in accordance with the recommendation of the Nominating and Governance Committee, after considering the experience, qualifications, attributes and skills of Dr. Lattin, the Board of Directors approved the waiver of the application of the mandatory retirement provision of our Corporate Governance Guidelines with respect to Dr. Lattin for fiscal 2010 so that he could stand for re-election to the Board of Directors at the annual meeting.

Section I: Introduction

This narrative describes the philosophy, approach and elements used by us and the Compensation and Development Committee of our Board of Directors to define, manage and review compensation paid to our named executive officers. The philosophy and management’s approach for executive compensation described below applies to the named executive officers with respect to 2009.

Our Compensation and Development Committee is responsible for the design and management of our executive compensation programs as well as the philosophy for all employee compensation, benefits, and development programs on a worldwide basis. The Compensation and Development Committee operates under a written charter, which is formally reviewed annually and revised as needed. The charter is available on our website at www.radisys.com under the investor relations tab.

Section II: Philosophy and Objectives of Executive Compensation Programs

The Compensation and Development Committee has adopted a philosophy of executive compensation that is based on performance and is competitive with other similar sized, high tech companies. Our executive compensation programs are designed to address the following key objectives:

• Attract and retain executives needed to achieve our business objectives. This is achieved through at least annual reviews of executive compensation and benefit programs to ensure market competitiveness.

• To substantially link executive compensation with near-term performance on operating plans. This is achieved through cash incentive programs which are directly aligned to key operating goals and strategic objectives.

• To provide a reward for longer-term strategic progress and shareholder value creation. This is achieved through the use of equity-based compensation programs, including the use of performance-based shares.

Section III: Process for Determining Executive Compensation

Roles and Responsibilities.

Roles of Committee: Our Board of Directors has delegated responsibility to the Compensation and Development Committee for final approval of decisions related to base salary, cash incentive targets, equity grants and payments for executive incentive plans, as well as any executive employment offers, executive change of control agreements, severance agreements and other executive compensation programs. The Compensation and Development Committee also guides executive development programs and succession planning in order to maintain and develop the Company’s leadership team. The Compensation and Development Committee maintains an annual calendar to guide the timing of its review, analysis, and decision making related to executive compensation, benefits, and development programs.

The Committee conducts a formal review of each executive’s compensation on an annual basis as part of the Company-wide merit review process or more frequently if needed. The review consists of the Committee comparing the cash and equity components of each executive’s pay to the market data for similar positions; considering recommendations provided by the Chief Executive Officer, Chief Financial Officer and Human Resources staff; assessing individual performance; and aligning any pay changes with market and Company performance. The Compensation and Development Committee reviews the mix of base salary, incentive cash compensation and equity compensation, but does not attempt to target a specific percentage allocation as each

9

compensation element is compared to market survey data. The Committee believes that the amount of “at risk” compensation tied to meeting company objectives should increase as an executive’s compensation and level of responsibility increases. “Tally sheets” have historically been used to consider and evaluate the total potential compensation of executives from all sources upon various scenarios and any benefits associated with termination of employment. Based on this analysis, the committee is able to make market based decisions that are aligned to the Company’s financial and strategic direction.

The Compensation and Development Committee assesses the performance of our Chief Executive Officer annually. The Chief Executive Officer performance review process includes a Chief Executive Officer’s self appraisal, a formal Board of Directors evaluation process as well as a performance appraisal delivered by the Chairman of the Board of Directors.

Role of Chief Executive Officer and Management: Under the supervision of the Compensation and Development Committee, our Chief Executive Officer, Chief Financial Officer and Human Resources staff have responsibility for the implementation of our executive compensation programs. The Committee reviews the recommendation from the Chief Executive Officer and makes all final compensation decisions. Our Chief Executive Officer is responsible for assessing the performance of each executive reporting to him.

Role of Surveys and Benchmarking: The Radford executive survey is the primary data source for executive compensation market data. The market, for the purposes of executive compensation benchmarking, is defined as high-tech companies with average revenues of $200M to $499M. A list of the companies included in our Radford survey market cut is set forth in Appendix A to this proxy statement.

Radford is a division of Aon Corporation that publishes an independent executive compensation survey and offers consulting services. We believe the Radford executive survey is a leading resource in the technology industry on competitive intelligence for technology executives in the U.S and provides a reliable market benchmark for our executive positions. The executive survey includes data from over 900 companies and more than 17,600 incumbents representing a wide range of technology sub-industries. The Committee does not use a formal peer group in determining executive compensation as there is no well-defined group of comparable publicly-traded companies in the United States operating in the same industry. As a result, the Committee believes that the broad technology industry comparison provided by the Radford survey is appropriate.

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

Role of the Compensation Consultant: Starting in 2010, the Committee has also retained Mercer, a subsidiary of March & McLennan Companies, Inc., to help supplement the current executive compensation benchmarking process and analysis.

Base Salaries.

As part of the review process, the amount of any annual merit increase to an executive’s base salary is determined based on a combination of a Board-approved compensation budget, the current position of the executive’s pay against market data and the executive’s experience, performance and results during the past year. An executive’s base salary is increased if warranted based on the executive’s experience, performance and business results, provided the resulting base salary remains within the targeted zone of the market data. By exception, our Compensation and Development Committee may determine that an individual executive’s base salary should be above (or below) the targeted zone due to extenuating factors. In this case, the executive’s compensation may be outside the targeted zone.

10

Cash Incentive Compensation.

Cash Incentive Plan: Based on the recommendations of our Chief Executive Officer, Radford benchmark data, and our compensation program philosophy, our Compensation and Development Committee assigns each executive an annual cash incentive target amount under our cash-based, pay-for-performance annual Incentive Compensation Plan (the “Cash Incentive Plan”). Payouts against these targets, as described in greater detail below, are mostly attributable to the attainment of achieving certain levels of non-GAAP operating income with some minor modulation based on corporate objectives as well as individual performance factors.

Our cash incentive target is expressed as a dollar amount for each executive, and the incentive pool for executives as well as all employees, is funded based on achievement against target levels of non-GAAP operating income. For this purpose, non-GAAP operating income is defined as GAAP operating income excluding the impact of amortization of acquired intangible assets, stock-based compensation, restructuring charges, a goodwill impairment charge and deferred tax asset write-offs or benefits. Non-GAAP operating income targets and resulting funding levels are established and approved by the Compensation and Development Committee at the beginning of each year through our annual operating plan process. Actual non-GAAP operating income results measured against these targets determine the size of the available incentive pool. If we under-achieve or over-achieve our objectives for non-GAAP operating income, the incentive pool is adjusted down or up accordingly. In addition, higher or lower achievement of individual annual and strategic objectives would also impact the payout to a lesser extent. The Compensation and Development Committee establishes the maximum payout which could be made on an annual basis at the beginning of the year. For example, the maximum payout which could have been made in 2009 was two times the targeted amount. Our corporate objectives are developed by our Chief Executive Officer and reviewed by our Board of Directors. The corporate objectives and progress towards these objectives are periodically reviewed by our Board of Directors and our Compensation and Development Committee during the year. Individual objectives for each executive officer are developed by the Chief Executive Officer in consultation with the affected executive and then reviewed by the Compensation and Development Committee. The Compensation and Development Committee reviews our Chief Executive Officer’s assessment of executive performance and the proposed cash incentive amounts to be paid to each executive. The Compensation and Development Committee ultimately decides the amounts paid to each executive with such qualitative modifications as the Compensation and Development Committee may make at its discretion.

MSBU Plan: In the case of two of our named executive officers, for 2009, based on the recommendations of our Chief Executive Officer, our Compensation and Development Committee assigned an additional cash incentive target amount under the MSBU Plan based on the amount of revenue generated by our media server business unit consistent with our annual operating plan. This additional cash incentive was not benchmarked against Radford benchmark data, but is intended to provide an additional incentive to reward superior performance for a focused objective. The Compensation and Development Committee used its business judgment to set the target amount under the MSBU Plan in an amount believed to be sufficient to provide a meaningful incentive to reach the performance targets and did not rely on any set formula or peer group percentile to determine the target amount.

Cash Incentive Overlay Program: In September 2009, our Compensation and Development Committee approved the cash incentive overlay program (the “Overlay Program”) to help drive meaningful transformation in productivity and cost within our operations and engineering organizations. The Compensation and Development Committee approved operations outsourcing performance goals and engineering performance goals and target incentive amounts based on the recommendation of the Chief Executive Officer and Chief Financial Officer. The Compensation and Development Committee compared the proposed cash incentive target amounts to Radford benchmark data, but did not seek to achieve any particular percentile. The Compensation and Development Committee also compared the proposed target cash incentive amounts to the total amount of potential compensation for each named executive officer. The Compensation and Development Committee exercised its business judgment in setting the target amount under the Overlay Program in an amount believed to be sufficient to provide a meaningful incentive to reach the performance targets and did not rely on any set formula or peer

11

group percentile to determine the target amount. Upon completion of the performance period, our Chief Financial Officer, with support from the Finance staff, will calculate the proposed payout amounts based on the performance results and the individual executive’s pre-existing targets. Our Compensation and Development Committee will then review and approve such proposed payout amounts.

Equity Compensation.

We believe that long-term equity incentives in the form of stock options, restricted stock, or other equity instruments are a highly effective way to align the interests of management and shareholders, and to motivate management to drive longer term shareholder value. Time-based equity incentives are made to executives under the RadiSys Corporation 2007 Stock Plan and performance-based equity incentives are made to executives under the RadiSys Corporation Long Term Incentive Plan (“LTIP”).

The 2007 Stock Plan: With respect to the allocation of time-based equity incentives under the RadiSys Corporation 2007 Stock Plan (the “2007 Stock Plan”), the Compensation and Development Committee uses equity values from Radford benchmark data as a reference point in determining the amounts of equity grants by executive position, which is reviewed and analyzed at least annually. In addition, the retentive value of past grants for each executive is reviewed to ensure that the value of unvested equity grants is in line with benchmarks and is of sufficient value to assure retention and strong performance incentive for the executive in future years. All equity grants to newly hired executives and annual (“refresher”) grants to existing executives are reviewed and approved by our Compensation and Development Committee, on the recommendation of the Chief Executive Officer, using the above mentioned factors of market data, the total retention value, and the executive’s projected level of future contribution. Grants of equity awards are made at predetermined times and are not intentionally scheduled to coincide with the disclosure of favorable or unfavorable information. Each year we review whether refresher grants are necessary to continue to motivate management and employees while providing long term incentives.

The Long Term Incentive Plan (LTIP): The LTIP is intended to create an incentive for exceptional performance in addition to our annual refresher stock program under the 2007 Stock Plan, which enables us to attract, retain and motivate senior executives and other key employees. The difference between the annual refresher stock program and LTIP is that the LTIP grants are performance based and participants are only eligible to receive these awards if certain financial or strategic metrics meet or exceed threshold targets established by our Compensation and Development Committee. These targets will be “stretch” goals above the targets in our operating plan and require superior corporate performance to be earned.

With respect to the allocation of performance-based shares from the LTIP in September 2009, the Compensation and Development Committee made the first tranche of grants of performance-based restricted stock units to participating executives, including all of the named executive officers. The Chief Executive Officer recommended the participants and target award amounts, and the Chief Financial Officer recommended the performance goal and calculation of payouts at various levels of non-GAAP earnings per share. The Compensation and Development Committee compared the target award amounts to the Radford benchmark data, but did not seek to achieve any particular percentile except with respect to the distribution of awards among the participant group as described below. The Compensation and Development Committee considered the goals necessary to achieve our strategic plan, the value of the proposed performance-based awards and the then-existing retentive value of the executive’s outstanding, vested and unvested equity awards at various stock prices, but did not assign any specified weight to any particular factor. Upon completion of the performance period, our Chief Financial Officer, with support from the Finance staff, will calculate the proposed award payout amounts based on the performance results and the individual executive’s target award amount. Our Compensation and Development Committee will then review and approve such proposed award payouts after financial review from our outside auditors. A second tranche of performance-based restricted stock unit grants is planned for 2010.

Section IV: Key Components of Executive Compensation and Impact of Performance on Compensation for Fiscal 2009

Our executive compensation program for 2009 includes three key components:

1. Cash compensation, which for 2009 included base salary, the Cash Incentive Plan based primarily on attaining certain levels of non-GAAP Operating Income and the MSBU Plan for two of our named executive officers based on attainment of revenue goals for our media server business unit. An additional cash incentive plan was implemented in 2009, with payout occurring in 2010 if performance goals are met.

2. Equity incentive awards, which for 2009 included time-based, non-qualified stock option awards under the 2007 Stock Plan and performance-based restricted stock units under the LTIP based on attainment of non-GAAP earnings per share performance targets.

3. Employee benefits, including health care insurance, employee stock purchase program under the RadiSys Corporation 1996 Employee Stock Purchase Plan (“ESPP”), 401(k) plan, flexible spending accounts, life insurance, and other benefits.

Our executive compensation program does not seek to achieve a specific mix of components, but rather each component is designed to provide competitive compensation comparable to similar companies with performance incentives for cash and equity compensation.

Cash Compensation

For 2009, our goal for an executive’s targeted base salary and cash incentive compensation was approximately equal to the 50^th percentile when compared to the Radford benchmark data. For base salaries, our objective for 2009 was that executive base salaries would be between the 25^th and 50^th percentile (median) of the data for our peer group. An executive’s base pay and resulting percentile are dependent on many factors such as current year market data, the executive’s experience and performance. It is believed that this positioning provides a sufficient retentive factor when coupled with the opportunity to earn compensation above the median through the cash incentive and equity plans as well as other programs described below.

The executive’s cash incentive target under the Cash Incentive Plan is designed to be a significant portion of executive compensation in order to create high incentive for our executives to perform against annual objectives. For 2009, the Cash Incentive Plan when paid at 100% was targeted to be at the 50^th to 75^th percentile when compared to the Radford benchmark data. By setting the potential incentive target to be between the 50^th to 75^th percentiles, our Compensation and Development Committee believes that we are encouraging our executives to achieve higher levels of performance with a strong retentive factor.

At the end of 2009, the base salary, cash incentive target and total cash compensation for our Chief Executive Officer and Chief Financial Officer was approximately at the following percentiles when compared to the Radford benchmark data.

	General Percentile Achieved for End of Year 2009
Named Executive Officer	Base Salary	Cash Incentive Target	Total Cash Compensation
Scott Grout	50th-55th	45th-50th	45th-50th
Brian Bronson	50th-55th	65th-70th	60th-65th

At the end of 2009, the general percentiles for the rest of the Named Executive Officers were between 40^th—55 ^th for base salary, 40^th—75 ^th for cash incentive targets and 40^th—65 ^th for total cash compensation.

Base Salary. Due to the uncertain economic climate, the Board of Directors decided to forego any Board and executive officer merit increases for 2009. In addition, each executive’s base salary was reviewed to ensure

13

that there were no significant retention risks and it was decided that no adjustments were needed because base salaries were within the acceptable percentile range. Further, improved base pay percentiles for four of the five positions at the end of 2009 relative to 2008 provided support for the decision to forego merit increases. In April 2010, target cash for executive officers, which includes base pay and variable targets, increased an average of 2.5 percent.

Cash Incentive Plan. On February 24, 2009, The Compensation and Development Committee reviewed the Cash Incentive Plan targets for each executive and identified that the Chief Executive Officer and Chief Financial Officer had targets and total cash percentiles that were well below the 50^th percentile when our goal was to be between 50^th—75 ^th percentiles. In addition, given the transformational work occurring within the company, the Committee felt it was a risk for these positions to be below the goal (Cash Incentive Targets at the beginning of 2009 were as follows: Chief Executive Officer—25^th to 30^th percentile; and Chief Financial Officer—35^th to 40^th percentile). The Compensation and Development Committee increased the Chief Financial Officer’s target cash amount from $161,160 to $211,160 and the Chief Executive Officer’s from $361,920 to $436,920.

For 2009, the Cash Incentive Plan was funded at 80.2%. Funding of the Cash Incentive Plan at 100% is based on our strategic non-GAAP operating income target, not the Company’s annual operating plan. Specifically, the 2009 non-GAAP operating income plan was $17.6 million and actual performance was $20.6 million or 116% of plan but fell short of our longer-term strategic target of $25.7 million resulting in a payout of 80.2%.

A total of $968,000 was paid to the named executive officers via the Cash Incentive Plan. $899,000, or 93% was attributable to actual 2009 non-GAAP operating income performance relative to target as mentioned above and $69,000 or 7% was attributable to the achievement of various shared Company and individual objectives such as balance sheet performance, customer satisfaction, employee development, manufacturing metrics, new design wins, new product introduction and process improvement. For 2009, the actual cash incentive payouts for each executive officer were as follows:

	2009 Incentive Target at 100% Funding		Actual 2009 Payout		% Attainment
Scott Grout	$	436,920	$	375,917	86	%
Brian Bronson	$	211,160	$	193,660	92	%
Anthony Ambrose	$	150,000	$	125,230	83	%
Christian Lepiane	$	162,330	$	138,691	85	%
John Major	$	160,000	$	134,392	84	%

MSBU Plan. The named executive officer participants in the MSBU Plan for 2009 are Messrs, Ambrose and Lepiane. Our media server business unit had a strong 2009, finishing at 109% of our annual operating plan. The target payouts associated with the MSBU Plan were set well above operating plan levels and were meant to be a significant stretch.

	2009 Performance Target		Actual 2009 Payout
Anthony Ambrose	$	56,056	$	28,028
Christian Lepiane	$	67,200	$	33,600

Because the performance goals under the MSBU Plan were not previously approved by the shareholders, the awards under the MSBU Plan are not intended to qualify as “performance-based compensation” for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). The plan has been discontinued for 2010 since the desired results have been achieved.

Cash Incentive Overlay Program. On September 30, 2009, the Compensation and Development Committee put in place the Overlay Program for certain of our employees to drive breakthrough Company transformations in

14

an accelerated timeframe. These initiatives are expected to be implemented by the third quarter of 2010 and, if successful, are estimated to save $1.0 to $2.0 million a quarter in manufacturing costs, reduce inventory levels by $5.0 to $10.0 million, and save $0.5 to $1.0 million a quarter in development costs, while at the same time enhancing our product development and operational capabilities. These are transformational objectives and there can be no assurance that these initiatives will fully achieve the desired results.

Awards under the Overlay Program will be based on Company performance as measured by two sets of goals: an operations outsourcing performance goal, which consists of achieving an operational overhead spend of $4.5 million or less in the second quarter of 2010, with additional conditions intended to incentivize sustainability of the achievements, and an engineering performance goal, which consists of achieving $1.0 million of R&D cost savings in the second quarter of 2010 with conditions of demonstrating continued support of our long-term strategy and the ability to sustain the cost savings through subsequent quarters. Attainment of the performance goals will be calculated by the Chief Financial Officer with the assistance of the human resources staff and submitted to the Compensation and Development Committee for review and approval. The performance period for the Incentive Program runs from October 1, 2009 to June 30, 2010 and will be calculated for payout during the calendar third quarter of 2010. Actual payouts under the Overlay 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 under the Cash Incentive Plan, which the Compensation and Development Committee in its business judgment determined would be an amount sufficient to provide a meaningful incentive for participants to achieve the aforementioned savings.

For 2010, under the Overlay Program target incentive amounts for the named executive officers are as follows: Mr. Grout—$218,460; Mr. Bronson—$105,580; Mr. Ambrose—$37,500; Mr. Lepiane—$20,000; and Mr. Major—$80,000. An amount of $620,000 will be targeted for participants other than named executive offices for an aggregate target payout of approximately $1.0 million to all participants. Because the performance goals under the Overlay Program were not previously approved by the shareholders, the awards under the Overlay Program are not intended to qualify as “performance-based compensation” for purposes of Section 162(m) of the Code.

Equity Incentive Awards.

The 2007 Stock Plan. For 2009, the annual equity grants made to each executive under the 2007 Stock Plan consisted solely of non-qualified stock options. The decision to grant exclusively stock options was due to the Company’s stock price and the ongoing effort to reduce overall burn rate under the 2007 Stock Plan. The Compensation and Development Committee’s objective is to provide equity grants to executives that are aligned to allocation distributions that would typically be found in companies of similar size. The Committee reviews the retentive value of past grants for each executive to ensure that the value of prior, unvested equity grants remains consistent with benchmarks and remains of sufficient value to assure retention and strong performance incentive for the executive in future years. If the Compensation and Development Committee determines that prior, unvested equity grants no longer provide a sufficient retentive incentive, it may use its business judgment without reference to a set formula or benchmark to increase future equity grants. Grants of equity awards are made at predetermined times and are not intentionally scheduled to coincide with the disclosure of favorable or unfavorable information. Each year we review to determine whether refresher grants are necessary to continue to motivate management and employees while providing long term incentives.

The Compensation and Development Committee reviewed and approved annual (“refresher”) grants to existing named executive officers (refer to the 2009 Grants of Plan Based Awards table below for actual share amounts). The total refresher stock budget for executives for 2009 was determined to be 380,000 shares based on availability within the option pool, general benchmarking and historical allocations. A typical allocation distribution based on position from the Radford benchmark data would be: Chief Executive Officer (Scott C. Grout)—37%; Chief Financial Officer (Brian Bronson)—13%; Vice President & General Manager of Communications Networks

15

(Anthony Ambrose)—11%; Vice President, Worldwide Sales (Christian Lepiane)—8%; Vice President, Global Operations (John T. Major)—8%. Adjustments were made to Messrs. Bronson’s, Lepiane’s and Ambrose’s allocations due to the low retentive value of the previous shares and their strong individual performance. Since Mr. Major received a recent new hire grants, his shares were adjusted to a grant amount lower than his allocation percentage.

Long Term Incentive Plan. On September 30, 2009, the Compensation and Development Committee made the first tranche of grants to participants under the LTIP, with a grant date of October 1, 2009. For the first tranche, the Compensation and Development Committee adopted a target performance goal of 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 December 31, 2012 with the first possibility of goal achievement of September 30, 2010 and subsequent goal achievement dates for each calendar quarter thereafter. Non-GAAP earnings per share for the LTIP for the first performance period is calculated as follows: 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 and as approved by the Compensation and Development Committee, plus other adjustments resulting from purchase accounting as determined by the Compensation and Development Committee, plus a fixed 20% effective tax rate notwithstanding the tax rate otherwise applicable in accordance with GAAP. The number of shares equals the weighted average shares outstanding during such quarter (calculated as required by GAAP with or without shares issuable upon conversion of any outstanding convertible notes and interest thereon so as to result in the most dilutive impact but disregarding shares earned and issued or issuable under the LTIP during such quarter) plus the total number of shares earned and issued or issuable with respect to all awards under the LTIP during such quarter.

When selecting the performance goal, the Compensation and Development Committee chose non-GAAP earnings per share because it felt, in its business judgment, that this metric would best reflect longer-term shareholder value creation but decided to fix the tax rate used in this calculation at 20% for the purpose of calculating non-GAAP earnings per share because in general, LTIP participants have little influence on the tax rate up or down and the Compensation and Development Committee felt would be inconsistent with the performance based objectives of the LTIP. Because this performance goal was not previously approved by the shareholders, the awards under the LTIP for the first performance period are not intended to qualify as “performance-based compensation” for purposes of Section 162(m) of the Code.

The performance goals for non-GAAP earnings per share range from $0.65 to $0.85 in increments with payouts ranging from 75% to 125% of the target payout amounts. The target payout amounts for the first performance period for the named executive officers were: Mr. Grout—161,000 shares; Mr. Bronson—75,000 shares; Mr. Ambrose—50,000 shares; Mr. Lepiane—50,000 shares; Mr. Major—50,000 shares. The number of shares awarded to each executive was intended to reflect a distribution among the executives roughly correlated to the distribution of similar performance-based equity awards to comparable positions in the Radford benchmark data.

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

Executive and Employee Benefits.

RadiSys provides employee benefit programs to the named executive officers that are the same as those benefits provided to other employees in the same country. Our U.S. based employee benefit programs include

16

medical/dental/vision plans, ESPP, 401(k) plan, tuition reimbursement, life insurance, short term disability and long term disability. Employee benefit programs are targeted to be approximately at the 50^th to 60^th percentile of Radford market data of employee benefit programs for similar high tech companies. Our employee benefit programs are benchmarked at least annually to ensure that program design reflects current market practices and is cost effective.

Our named executive officers, certain other senior employees and members of our Board of Directors are also eligible to participate in the RadiSys Corporation Deferred Compensation Plan. For further description of our Deferred Compensation Plan, please refer to the narrative following the 2009 Nonqualified Deferred Compensation Table. The gains or losses of participants in the Deferred Compensation Plan based on their investment choices are not a factor in determining an executive’s base salary, incentive cash incentive payments, equity awards or any other forms of reward or compensation.

We do not provide our executives with any special perquisites such as club memberships, pension plans, automobile allowances or dwellings for personal use. Relocation packages to newly hired executives and other newly hired employees are defined within our hiring policy and are based on standard market practices for executive level relocation.

Severance and Change of Control Arrangements.

Our named executive officers are parties to various severance arrangements, change of control agreements, or both, entered into pursuant to guidelines adopted by our Compensation and Development Committee. The Compensation and Development Committee believes that these agreements may be necessary or advisable to keep executive officers focused on the best interests of shareholders at times that may otherwise cause a lack of focus due to personal economic exposure and extreme turmoil for RadiSys. Further, the Compensation and Development Committee believes that they are necessary or advisable for retentive purposes to provide a measure of support to our named executive officers who may receive offers of employment from competitors that would provide severance or change of control benefits. Consistent with the practice of a substantial number of companies in our peer group, the change of control agreements provide for a “double trigger” payout only in the event there is a change in control and the executive officer is either terminated from his or her position (other than for cause, death or disability) or resigns for “good reason,” which generally means that he or she is moved into a position that represents a substantial change in responsibilities or is required to relocate a substantial distance within a limited period of time after the transaction (i.e. these agreements do not become operative unless both events occur). See “Executive Compensation—Potential Post-Employment Payments” for a description of the severance and change of control agreements with our named executive officers.

Section V: Deductibility of Compensation

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

(1) The amounts included in the Stock Awards and Option Awards columns include the aggregate grant date fair value of stock and option awards granted in the fiscal year computed in accordance with FASB ASC Topic 718. We continue to use the Black-Scholes model to measure the grant date fair value of stock options. For a discussion of the valuation assumptions used to value the options, see Note 17 to our Consolidated Financial Statements included in our annual report on Form 10-K for the fiscal year ended December 31, 2009. We compute the grant date fair value of restricted stock as the closing price of our shares as quoted on the Nasdaq Global Select Market (“Nasdaq”) on the date of grant or the first date of the underlying service period, whichever occurs first.

(2) The amounts included in the Stock Awards column for 2009 are performance awards under the LTIP valued at the probable outcome of the performance conditions as of the grant date. The table below details the maximum potential value of the awards in 2009.

(3) The Summary Compensation Table only requires disclosure of above-market or preferential returns on nonqualified deferred compensation. The 2009 Nonqualified Deferred Compensation Table below discloses all

18

earnings under our Non-Qualified Deferred Compensation Plan during 2009. Participants in our Non-Qualified Deferred Compensation Plan make voluntary contributions to their accounts and in some cases we make matching contributions to the extent that a participant loses the Company match in our 401(k) plan due to the effect of participation in the Non-Qualified Deferred Compensation Plan. Participants elect to benchmark earnings on their accounts to the performance of third-party investment funds available to them under the Non-Qualified Deferred Compensation Plan. Participants select from among the funds available to them. Earnings are calculated and applied to participant accounts daily and may be positive or negative, based on individual fund performance. Although the funds offered to participants under our Non-Qualified Deferred Compensation Plan differ from those under our 401(k) plan, the number of funds and investment objectives of each fund are similar to those under the 401(k) plan. In accordance with SEC rules and publicly available interpretations of these rules by the SEC Staff, earnings on deferred compensation invested in third-party investment vehicles, such as mutual funds, need not be reported as compensation on the Summary Compensation Table.

(3) Represents the possible payout range during the 2009 fiscal year for the Cash Incentive Plan. Minimum levels of non-GAAP operating income and achievement of individual annual and strategic objectives must be met before there is any payout into the pool under the plan, which means that the minimum payout of any named executive officer’s individual cash incentive payment cannot be determined.

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

Narrative Description of Additional Material Factors—Summary Compensation Table & 2009 Grants of Plan-Based Awards Table

Equity Incentive Plans: Stock option awards are made under the 2007 Stock Plan. Grants of stock options become exercisable for one-third of the total option shares on the first anniversary of the date of grant and become exercisable in monthly increments equal to 1/36th of the total option shares, cumulatively, each month thereafter, becoming fully exercisable on the 3rd anniversary of the date of grant. The term of each option grant is seven years. The grants of the restricted stock units are made under the LTIP. No consideration is payable by the named executive for grants of restricted stock units/awards. The vesting of the shares will be determined upon us reaching a target performance goal of non-GAAP earnings per share of $0.75. It is measured as the cumulative sum over four consecutive quarters during the first performance period of October 1, 2009 to December 31, 2012 with a first goal achievement date of September 30, 2010 and subsequent goal achievement dates for each calendar quarter thereafter. The performance goals for non-GAAP earnings per share range from $0.65 to $0.85 in increments with payouts ranging from 75% to 125% of the target payout amounts.

The grant dates for equity awards during 2009 were established by our Compensation and Development Committee during meetings prior to each grant date.

Dividend and dividend equivalents are not payable on shares subject to performance awards in the LTIP until the shares are earned and issued.

Non-Equity Incentive Plans: We maintain the Cash Incentive Plan in which executive officers are eligible for potential incentive payments dependent upon the level of achievement of non-GAAP operating income and other stated corporate goals and department/individual performance goals.

The actual incentive payouts are calculated and paid semi-annually. Cash incentive awards earned between January 1 and June 30 are generally paid in early August; cash incentive awards earned between July 1 and December 31 are generally paid in the following February.

In September 2007, our Compensation and Development Committee approved the MSBU Plan. The MSBU Plan is a cash-based motivation and reward program for selected members of our sales and marketing departments who can most directly impact revenues of our media server business. Messrs. Ambrose and Lepiane, two of our named executive officers, participate in the MSBU Plan. Payouts under the MSBU Plan are determined based on the achievement of pre-determined revenue objectives of our media server business. This plan has been discontinued for 2010, since the desired results have been achieved.

Narrative Disclosure Describing Material Factors—2009 Nonqualified Deferred Compensation Table

Executives and other select employees can participate in a deferred compensation program. Executive contributions to this program may be made from salary, sales commission payments and/or cash incentive awards, excluding the MSBU Plan. A maximum of 75% of salary and 75% of sales commission payments and/or cash incentive awards may be deferred. Base salary, cash incentive awards and commission elections apply to compensation earned during the plan year. Employee contributions are credited to the account balance on the date they would otherwise have been paid to the participant. We only make Company contributions to the Non-Qualified Deferred Compensation Plan in situations where such contributions are needed to restore any match lost in the 401(k) plan due to the effect of participation in the Non-Qualified Deferred Compensation Plan. Any such matching contributions are credited as soon as practicable following the end of the plan year.

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

Aggregate Distributions are any distributions made to a participant measured from participation commencement in the Non-Qualified Deferred Compensation Plan to the end of the proxy reporting period. Distributions are paid in the form elected by the participant in the Participation Agreement entered into prior to the beginning of each plan year. The participant may elect to receive payment during employment or upon separation from service. Available forms of payment made during employment are lump sum or annual installments over a maximum of five years. Available forms of payment made following a separation from service are lump sum or annual installments over a maximum of 15 years.

POTENTIAL POST-EMPLOYMENT PAYMENTS

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

On December 24, 2008, we entered into a Change of Control Agreement with our Chief Executive Officer, Scott C. Grout, to update a preexisting agreement to comply with changes in tax laws. Mr. Grout’s Change of Control Agreement provides that if we terminate his employment with us (other than for cause, death or disability) or if he terminates his employment with us for good reason within 12 months following a change of control or within three months preceding a change of control, Mr. Grout is entitled to receive severance pay in a cash amount equal to 12 months of Mr. Grout’s annual base pay at the highest annual rate in effect at any time within the 12-month period preceding the date of termination. Upon such a termination, Mr. Grout would receive 25% of the severance pay on the date that is six months and one day following termination and the remaining 75% would be paid in six periodic payments on regular paydays, provided that the first remaining payment will be an amount equal to one-half of the aggregate amount of the remaining payments so long as during the period of remaining payments Mr. Grout does not serve as or become a director, officer, partner, limited partner, employee, agent, representative, material stockholder, creditor, or consultant of or to, or serve in any other capacity with any business worldwide that shall in any manner (i) engage or prepare to engage in any business which competes directly with us or (ii) solicit, hire, or otherwise assist in any effort that attempts to employ or otherwise utilize the services of any of our employees. Upon such termination, and in addition to severance pay, Mr. Grout is also entitled to receive COBRA benefits for 12 months. Upon such termination, all stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other similar awards granted to Mr. Grout shall be immediately exercisable in full in accordance with the applicable provisions of the relevant award agreement and the plan; and any risk of forfeiture included in any restricted stock or other similar award shall immediately lapse. Stock options (other than those considered Incentive Stock Options) and stock appreciation rights shall also be amended to permit Mr. Grout to exercise such stock options and stock appreciation rights for a period of time equal to the earlier of (i) the period of 180 days after the date of Mr. Grout’s termination; or (ii) the date that each stock option and stock appreciation right would otherwise expire by its original terms had Mr. Grout not terminated. Had the Change of Control Agreement been in effect and a triggering event occurred on December 31, 2009, such that Mr. Grout would become entitled to benefits under his Change of Control Agreement, Mr. Grout would have been entitled to receive the payments described below.

On December 24, 2008, we entered into an Employment Agreement including Severance Agreement with Scott C. Grout, to update a preexisting agreement to comply with changes in tax laws. If Mr. Grout’s employment with us is terminated other than for cause and contingent on Mr. Grout signing a release agreement, Mr. Grout is entitled to receive severance pay in a lump sum cash amount equal to 12 months of Mr. Grout’s annual base pay at the rate in effect immediately before the date of termination. Had Mr. Grout’s employment been terminated by us without cause, and if he had signed a release agreement, on December 31, 2009, Mr. Grout would have become entitled to receive the payment described below.

On December 22, 2008, we entered into a Change of Control Agreement with our Chief Financial Officer, Brian Bronson, to update a preexisting agreement to comply with changes in tax laws. Mr. Bronson’s Change of

23

Control Agreement provides that if we terminate his employment with us (other than for cause, death or disability), or if his employment terminates as a result of a requirement that he accept a position greater than 25 miles from his current work location or a position of less total compensation within 12 months following a change of control, Mr. Bronson is entitled to receive severance pay in a cash amount equal to 12 months of Mr. Bronson’s annual base pay at the highest annual rate in effect at any time within the 12-month period preceding the date of termination. Upon such termination, and in addition to severance pay, Mr. Bronson is also entitled to receive COBRA benefits for 12 months. Upon such termination, all stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other similar awards granted to Mr. Bronson shall be immediately exercisable in full in accordance with the applicable provisions of the relevant award agreement and the plan; and any risk of forfeiture included in any restricted stock or other similar award shall immediately lapse. Stock options (other than those considered Incentive Stock Options) and stock appreciation rights shall also be amended to permit Mr. Bronson to exercise such stock options and stock appreciation rights for a period of time equal to the earlier of (i) the period of 180 days after the date of Mr. Bronson’s termination; or (ii) the date that each stock option and stock appreciation right would otherwise expire by its original terms had Mr. Bronson not terminated. Had the Change of Control Agreement been in effect and a triggering event occurred on December 31, 2009, such that Mr. Bronson would become entitled to benefits under his Change of Control Agreement, Mr. Bronson would have been entitled to the payments detailed below.

On December 22, 2008, we entered into an Executive Severance Agreement with Brian Bronson, to update a preexisting agreement to comply with changes in tax laws. If Mr. Bronson’s employment with us is terminated other than for cause, death or disability, Mr. Bronson will be entitled to (i) a payment of twelve months base pay, (ii) up to twelve months of continued coverage pursuant to COBRA under the Company’s group health plan, (iii) stock-based incentive compensation plan payout under our LTIP pursuant to the terms of and within the periods specified in the LTIP (when implemented), and (iv) partial cash-based incentive compensation plan payout, if any. Had Mr. Bronson’s employment been terminated by us without cause on December 31, 2009, Mr. Bronson would have become entitled to receive the payment described below.

On December 31, 2008, we entered into a Change of Control Agreement with our Vice President of Sales, Christian Lepiane, to update a preexisting agreement to comply with changes in tax laws. Mr. Lepiane’s Change of Control Agreement provides for severance pay in a cash amount equal to 9 months of his annual base pay at the highest annual rate in effect at any time within the 12-month period preceding the date of termination. Mr. Lepiane is entitled to receive the severance pay if we terminate his employment with us (other than for cause, death or disability), or if his employment terminates as a result of a requirement that he accept a position with a title of less than Vice President or greater than 25 miles from his current work location, within three months before, or within twelve months after, a change of control. Upon such termination, and in addition to severance pay, Mr. Lepiane is also entitled to receive COBRA benefits for 9 months. Had the Change of Control Agreement been in effect and a triggering event occurred on December 31, 2009, such that Mr. Lepiane would become entitled to benefits under his Change of Control Agreement, Mr. Lepiane would have been entitled to the payments detailed below.

On December 31, 2008, we entered into an Employment Agreement including Severance Agreement with Christian Lepiane, to update a preexisting agreement to comply with changes in tax laws.

(1) The amounts included in the Stock Awards and Option Awards columns include the aggregate grant date fair value of stock and option awards granted in the fiscal year computed in accordance with FASB ASC Topic 718. We continue to use the Black-Scholes model to measure the grant date fair value of stock options shares. For a discussion of the valuation assumptions used to value the options, see Note 17 to our Consolidated Financial Statements included in our annual report on Form 10-K for the fiscal year ended December 31, 2009. A supplemental table following these footnotes sets forth: (i) the aggregate number of stock awards and option awards outstanding at 2009 fiscal year end; (ii) the aggregate number of stock awards and options awards granted during fiscal 2009; and (iii) the grant date fair value of equity awards granted by us during fiscal 2009 to each of our directors who was not an executive officer.

(2) The 2009 Director Compensation Table only requires disclosure of above-market or preferential returns on nonqualified deferred compensation. Participants in our Non-Qualified Deferred Compensation Plan make voluntary contributions to their accounts and in some cases we make matching contributions to the extent that a participant loses the Company match in our 401(k) plan due to the effect of participation in the Non-Qualified Deferred Compensation Plan. Participants elect to benchmark earnings on their accounts to the performance of third-party investment funds available to them under the Non-Qualified Deferred Compensation Plan. Participants select from among the funds available to them. Earnings are calculated and applied to participant accounts daily and may be positive or negative, based on individual fund performance. Although the funds offered to participants under our Non-Qualified Deferred Compensation Plan differ from those under our 401(k) plan, the number of funds and investment objectives of each fund are similar to those under the 401(k) plan. In accordance with SEC rules and publicly available interpretations of these rules by the SEC Staff, earnings on deferred compensation invested in third-party investment vehicles, such as mutual funds, need not be reported as compensation on the Director Compensation Table.

(1) Includes both vested and unvested options to purchase our common stock.

(2) Stock grants to our Board of Directors are made pursuant to the terms of the 2007 Stock Plan. The exercise price of options granted to non-employee directors during 2009 was the fair market value of our common stock on the date of grant and the term of each option is seven years. For stock option grants made in 2009, the exercise price was $8.66. Grants of stock options become exercisable for one-third of the total option shares on the first anniversary of the date of grant and become exercisable in monthly increments equal to 1/36th of the total option shares, cumulatively, each month thereafter, becoming fully exercisable on the 3rd annual anniversary of the date of grant.

(3) Amounts in this column represent the fair value of stock options, calculated in accordance with FAS123(R). For option awards, that number is calculated by multiplying the Black-Scholes value by the number of options awarded.

Narrative Disclosure of Director Compensation

During 2009, each director who was not employed by us was compensated as follows:

Director annual retainer	$	28,000
Chairman of the Board annual retainer	$	57,000
Audit Committee Chairman	$	12,500
Compensation and Development Committee Chairman	$	10,000
Nominating and Governance Committee Chairman	$	7,000

In addition, non-employee directors receive an annual equity grant of 15,000 non-qualified stock options (18,000 in 2009 in the case of the Chairman), vesting over a three-year period as described above. Newly appointed directors, if any, receive a similar grant of 30,000 non-qualified stock options upon appointment to the Board of Directors with “refresher” annual equity grants to commence during the next full year they are in office. Directors are also reimbursed for reasonable expenses incurred in attending meetings.

Compensation and Development Committee Chairman	$	10,000
Nominating and Governance Committee Chairman	$	8,000
Compensation and Development Committee membership	$	5,000
Nominating and Governance Committee membership	$	4,000

Non-employee directors are expected to acquire and hold a minimum of 5,000 shares or $100,000 worth of our common stock, whichever is the lesser value, and that minimum amount is expected to be reached within three to five years of becoming a director. Of our non-employee directors, five have already reached this ownership goal and two are within the three to five year period to reach this goal. Directors who are our employees receive no separate compensation as directors.

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

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

Assessment of Risk Related to Compensation Policies and Practices

We regularly review and assess our compensation policies and practices to determine whether they are reasonably likely to have a material adverse effect on the Company. The assessment is conducted by management, which reviews both our equity and cash incentive compensation programs for the presence of certain elements that could encourage our employees to take unnecessary or excessive risks; the ratios and level of incentive to fixed compensation, annual to long-term compensation and cash to equity compensation; the percentage of compensation expense as compared to the business units revenues; and the presence of other design features that may serve to mitigate risk taking, such as the use of multiple performance measures, caps on payments and similar features. Management’s assessment of our compensation policies is then reviewed by the Compensation and Development Committee and discussed with the whole Board of Directors in connection with the risk oversight function.

We have concluded that our programs are appropriately tailored to encourage employees to grow our business, but not encourage them to do so in a way that poses unnecessary or excessive material risk to us. More specifically, our compensation programs are designed to balance the following elements: elements that reward different aspects of short-term and long-term performance; incentive compensation that rewards performance based on a variety of different shared and individual objectives; awards that are paid based on results, awards paid in cash and awards paid in equity, which have a value that depends on long-term shareholder return; and compensation with fixed and variable components, so that executives have both competitive remuneration to encourage retention and opportunities to earn more by successfully executing our business strategy.

In addition, our compensation programs incorporate controls such as caps on potential payouts under incentive plans (to reduce incentives to sacrifice long-term performance for short-term goals). Overall, while risk is a necessary element in any business strategy, we have concluded that our compensation policies and practices, when coupled with our personnel performance and development programs, provide an appropriate balance to encourage superior performance while mitigating excessive risk-taking.

CORPORATE GOVERNANCE

Our Board of Directors has affirmatively determined that each of C. Scott Gibson, Ken J. Bradley, Richard J. Faubert, Dr. William W. Lattin, Kevin C. Melia, Carl W. Neun, and Lorene K. Steffes are “independent directors” as defined by the SEC rules and within the meaning of the Nasdaq Listing Rule 5605(a)(2) and, therefore, a majority of our Board of Directors is currently independent as so defined. Through February 16, 2010, Dr. Lattin was also a member of the Board of Directors of Merix Corporation which builds printed circuit boards for us, and Mr. Bradley is a member of the Board of Directors of SynQor Inc., which supplies power converters to us. We do not view either Dr. Lattin’s former position with Merix Corporation or Mr. Bradley’s position with SynQor Inc. as a conflict of interest or as a material relationship that would prevent either of them from being an independent director.

We have implemented corporate governance policies that are designed to strengthen the accountability of our Board of Directors and management team, thereby aiming to achieve long-term shareholder value.

The Board is actively involved in oversight of risks that could affect the Company. This oversight is conducted primarily through committees of the Board, as disclosed in the descriptions of each of the committees below and in the charters of each of the committees, but the full Board has retained responsibility for general oversight of risks. The Board satisfies this responsibility through full reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within the Company.

Our Board of Directors has adopted a Code of Ethics applicable to each of our directors, officers, employees and agents including our Chief Executive Officer, Chief Financial Officer or persons performing similar functions. Our Code of Ethics is available on our website at www.radisys.com under Investor Relations/Corporate Governance.

In addition, our Board of Directors has implemented a process whereby shareholders may send communications directly to its attention. Any shareholder desiring to communicate with our Board of Directors, or one or more members of our Board of Directors, should communicate in writing addressed to our Corporate Secretary. Our Corporate Secretary has been instructed by our Board of Directors to promptly forward all such communications to the specified addressees. Shareholders should send communications directed to our Board of Directors to 5445 NE Dawson Creek Drive, Hillsboro, Oregon 97124, Attention: Corporate Secretary.

Our Board of Directors held six regularly scheduled meetings during the fiscal year ended December 31, 2009. In 2009, independent directors met on a regularly scheduled basis in executive sessions without our Chief Executive Officer or other members of the our management present. The Chairman of the Board presides at these meetings.

Each director attended all of the regularly scheduled meetings of our Board of Directors and the committees of which he or she was a member. We encourage, but do not require, our Board of Directors’ members to attend the annual shareholders meeting. Last year, all of our directors attended the annual shareholders meeting.

AUDIT COMMITTEE REPORT

The Audit Committee of the Board of Directors of RadiSys Corporation (the “Company”) has oversight responsibility relating to the corporate accounting, reporting practices, and the quality and integrity of the Company’s financial reports; compliance with legal and regulatory requirements and the maintenance of ethical standards by the Company; the maintenance by the Company of effective internal controls; and independence and performance of the Company’s independent registered public accounting firm. The Audit Committee is composed of three non-employee directors and operates under a written charter that it has adopted and approved pursuant to authority delegated to it by the Board. The Audit Committee charter can be accessed at www.radisys.com under Investor Relations/Corporate Governance. Each Audit Committee member meets the independence requirements of Nasdaq listing standards and the Board of Directors has determined that each of the members of the Audit Committee meets the Nasdaq listing standards’ regulatory requirements for financial literacy and that each member is an “audit committee financial expert” as defined under the SEC rules.

The Company’s management is responsible for the financial reporting process, including the system of internal controls, and for the preparation of consolidated financial statements in accordance with U.S. generally accepted accounting principles. The Company’s independent registered public accounting firm is responsible for auditing those financial statements and expressing an opinion as to their conformity with U.S. generally accepted accounting principles. The Audit Committee acts in an oversight capacity, and its responsibility is to monitor and review these processes. In its oversight role the Audit Committee relies, without independent verification, on

• management’s representation that the Company’s consolidated financial statements have been prepared with integrity and objectivity and in conformity with U.S. generally accepted accounting principles, and

• the report of the Company’s independent registered public accounting firm, with respect to the Company’s consolidated financial statements.

In this context, the Audit Committee held nine meetings in 2009. At each of these meetings, the Audit Committee met with senior members of the Company’s financial management team, the Company’s counsel and the Company’s independent registered public accounting firm. The Audit Committee held private sessions at each of its meetings with the independent registered public accounting firm, at which candid discussions of financial management, accounting and internal control issues took place. The Audit Committee reviewed with the independent registered public accounting firm the overall scope and plans for their audit, the results of audit examinations, evaluations by the auditors of the Company’s internal controls and the quality of the Company’s financial reporting. The Audit Committee also held private sessions at each of its meetings with the Chief Financial Officer at which candid discussions of financial management, accounting and internal control issues took place.

¹ This Compensation and Development Committee Report, in addition to the section entitled “Audit Committee Report” are not “soliciting material,” are not deemed “filed” with the SEC and are not to be incorporated by reference in any filing of the Company under the Securities Act of 1933 or the Securities Exchange Act of 1934, regardless of date or any general incorporation language in such filing.

32

The Audit Committee reviewed the audited consolidated financial statements for the fiscal year December 31, 2009 with management and its independent registered public accounting firm, including a discussion of the quality, not simply the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the consolidated financial statements. In addressing the quality of management’s accounting standards, the Audit Committee sought management’s representation that the audited consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles.

The Audit Committee also discussed with the independent registered public accounting firm matters required to be discussed with audit committees under generally accepted auditing standards, including, among other things, matters related to the conduct of the audit of the Company’s consolidated financial statements and the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (Communication with Audit Committees). SAS 61 requires the Company’s independent registered public accounting firm to provide the Audit Committee with additional information regarding the scope and results of their audit of the Company’s consolidated financial statements, including:

• their responsibility under U.S. generally accepted auditing standards;

• significant accounting policies;

• management judgments and estimates;

• any significant audit adjustments;

• any disagreements with management; and

• any difficulties encountered in performing the audit.

The Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the independent registered public accounting firm’s independence. When considering the independent registered public accounting firm’s independence, the Audit Committee discussed whether the independent registered public accounting firm’s provision of services to the Company beyond those rendered in connection with their audit and review of the Company’s consolidated financial statements was compatible with maintaining their independence. The Audit Committee also reviewed, among other things, the amount of fees paid to the independent registered public accounting firm for audit and non-audit services.

Based on the Audit Committee’s review and these meetings, discussions and reports, and subject to the limitations of the Audit Committee’s role and responsibilities referred to above and in the Audit Committee Charter, the Audit Committee recommended to the Board that the Company’s audited consolidated financial statements for fiscal year December 31, 2009 be included in the Company’s annual report on Form 10-K. The Audit Committee, pursuant to authority delegated to it by the Board, has appointed KPMG LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2010.

The Audit Committee has considered whether the provision of the services covered by these fees is compatible with maintaining the principal auditor’s independence. The Audit Committee has adopted a policy for the pre-approval of services provided by the independent registered public accounting firm. Under the policy, all audit and non-audit services to be performed by the independent registered public accounting firm must be presented to the Audit Committee in writing prior to the commencement of such services. The proposal must include a description and purpose of the services, estimated fees and other terms of the engagement. The Audit Committee may delegate to the Chairman of the Audit Committee the authority to grant pre-approvals. Any pre-approvals made by the Chairman pursuant to this delegation shall be presented to the full Audit Committee at its next scheduled meeting following such pre-approvals.

PROPOSAL 2: TO RATIFY THE AUDIT COMMITTEE’S APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has appointed KPMG LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2010. During the 2009 fiscal year, KPMG LLP served as the Company’s independent registered public accounting firm. Although the Company is not required to seek shareholder approval of this appointment, the Board believes it to be sound corporate governance to do so. If a majority of the votes cast on this matter are not cast in favor of the appointment of KPMG LLP, the Audit Committee will reconsider its appointment.

Representatives of KPMG LLP will be present at the annual meeting and will be available to respond to appropriate questions. They do not plan to make any statement, but will have the opportunity to make a statement if they wish.

Recommendation by the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE “FOR” THE PROPOSED RATIFICATION OF THE AUDIT COMMITTEE’S APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

Description of Equity Compensation Plans Not Adopted by Shareholders

2001 Nonqualified Stock Option Plan.

In February 2001, we established the 2001 Nonqualified Stock Option Plan, under which 2,250,000 shares of the our common stock were reserved as of December 31, 2006. The 2001 Nonqualified Stock Option Plan was adopted without shareholder approval prior to the amendment to the then-applicable Nasdaq rules requiring shareholder approval of equity compensation plans. Grants under the 2001 Nonqualified Stock Option Plan were eligible to be awarded to selected employees, who are not executive officers or directors of the Company. The purpose of the 2001 Nonqualified Stock Option Plan was to enable the Company to attract and retain the services of selected new employees of the Company or any parent or subsidiary of the Company. Unless otherwise stipulated in the plan document, the Board of Directors, at their discretion, determines the exercise prices (which may not be less than the fair market value of the Company’s common stock at the date of grant), vesting periods, and the expiration periods, which are a maximum of 10 years from the date of grant.

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

RadiSys Corporation Stock Plan For Convedia Employees.

On August 31, 2006, our Compensation and Development Committee adopted the RadiSys Corporation Stock Plan for Convedia Employees (“Convedia Stock Plan”) for awards to be made in connection with our acquisition of Convedia Corporation. The Convedia Stock Plan was adopted without shareholder approval in reliance upon the exception provided under the Nasdaq Listing Rule 5635(c)(4) relating to awards granted to new employees of the Company, including grants to transferred employees in connection with a merger or other acquisition. The Convedia Stock Plan became effective as of September 1, 2006. The Convedia Stock Plan permits the granting of stock options, restricted stock and restricted stock units. The maximum number of shares of common stock with respect to which awards may be granted is 365,000 shares (subject to adjustment in accordance with the Convedia Stock Plan). In order to comply with the former Nasdaq Listing Rule 5635, the awards may only be granted to employees transferred from Convedia Corporation in connection with our acquisition of Convedia Corporation and in connection with the future hiring of new employees of Convedia Corporation by us. Unless sooner terminated by our Board of Directors, the Convedia Stock Plan will terminate on the tenth anniversary of its effective date of September 1, 2006. The Convedia Stock Plan provides that the Committee will determine the option price at which common stock may be purchased, but the price will not be less than the fair market value of the common stock on the date the option is granted. The Committee will determine the term of each option, but no option will be exercisable more than 10 years after the date of grant. The Convedia Stock Plan provides for certain terms and conditions pursuant to which restricted stock and restricted stock units may be granted under the Convedia Stock Plan. Each grant of restricted stock and restricted stock units must be evidenced by an award agreement in a form approved by the Committee. The vesting of restricted stock or restricted stock units may be conditioned upon the completion of a specified period of employment, upon attainment of specified performance goals and/or upon such other criteria as the Committee determines.

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

PROPOSAL 3: TO APPROVE AN AMENDMENT TO THE RADISYS CORPORATION 2007 STOCK PLAN

The purpose of the 2007 Stock Plan is to attract and retain the services of directors and selected employees and consultants of the Company or any parent or subsidiary of the Company, by providing means of granting awards of incentive stock options, nonstatutory stock options, stock appreciation rights (“SARs”), restricted stock, performance shares and performance units (collectively, the “Awards”).

The Board of Directors believes that long-term incentive awards in the form of stock options, restricted stock, or other equity instruments are a highly effective way to link the interests of management and shareholders, and to motivate management to drive longer term shareholder value.

As of June 21, 2010, out of a total of 3,200,000 shares reserved for issuance under the 2007 Stock Plan, 2,619,715 shares had been issued, leaving 580,285 shares available for issuance. The Board of Directors believes additional shares will be needed under the 2007 Stock Plan to provide appropriate incentives to employees, directors and others. Accordingly, the Board of Directors has approved an amendment to the 2007 Stock Plan, subject to shareholder approval, to reserve an additional 500,000 shares for issuance under this plan, thereby increasing the total number of shares of the Company’s common stock reserved for issuance under the 2007 Stock Plan from 3,200,000 to 3,700,000.

Certain provisions of the 2007 Stock Plan are summarized below. The complete text of the 2007 Stock Plan, marked to show the proposed amendment, is attached to this document as Appendix B.

Description of the 2007 Stock Plan

The following paragraphs provide a summary of the principal features of the 2007 Stock Plan. This summary does not purport to be complete and is subject to, and qualified in its entirety by, the provisions of the 2007 Stock Plan, which is attached hereto as Appendix B. Capitalized terms used herein and not defined shall have the meanings set forth in the 2007 Stock Plan.

Purpose. The purpose of the 2007 Stock Plan is to attract and retain the services of directors and selected employees and consultants of the Company or any parent or subsidiary of the Company.

Awards. The 2007 Stock Plan permits the grant of incentive stock options, non-statutory stock options, stock appreciation rights (“SARs”), restricted stock (including restricted stock units), performance shares and performance units (collectively, the “Awards”).

Stock Subject to the 2007 Stock Plan. If this proposal to amend the 2007 Stock Plan to add an additional 500,000 shares for issuance under this plan is approved by our shareholders, the number of shares of our common stock reserved for issuance under the 2007 Stock Plan will be 3,700,000 shares.

Any shares subject to options or SARs will be counted against the numerical limits of the 2007 Stock Plan as one share for every share subject thereto. Any shares or units subject to restricted stock, performance shares or performance units with a per share or per unit purchase price lower than 100% of fair market value on the date of grant will be counted against the numerical limits of the 2007 Stock Plan as two shares for every one share and, if returned to the 2007 Stock Plan, will be returned to the 2007 Stock Plan as two shares for every one share returned to the 2007 Stock Plan.

Unpurchased, forfeited or repurchased shares will remain available for future grants under the 2007 Stock Plan. With respect to SARs, when a stock-settled SAR is exercised, the shares subject to the SAR agreement will be counted against the number of shares available for future grant or sale under the 2007 Stock Plan, regardless of the number of shares used to settle the SAR upon exercise. The 2007 Stock Plan does not permit shares used to pay the exercise price of an option or withheld for taxes to be added back to the shares available for future grants.

37

Administration. The 2007 Stock Plan may be administered by the Board of Directors or a committee appointed by the Board of Directors (the “Administrator”). Our Compensation and Development Committee is the current Administrator. Subject to the provisions of the 2007 Stock Plan, the Administrator has the authority to: (1) interpret the 2007 Stock Plan and apply its provisions, (2) prescribe, amend or rescind rules and regulations relating to the 2007 Stock Plan, (3) select the persons to whom Awards are to be granted, (4) subject to limitations of the 2007 Stock Plan as applicable to each type of Award, determine the number of shares to be made subject to each Award, (5) determine whether and to what extent Awards are to be granted, (6) determine the terms and conditions applicable to Awards generally and to each individual Award (including the provisions of the Award agreement), (7) amend any outstanding Award subject to applicable legal restrictions, (8) authorize any person to execute, on our behalf, any instrument required to effect the grant of an Award, (9) approve forms of Award agreement for use under the 2007 Stock Plan, (10) allow participants to satisfy withholding tax obligations by electing to have us withhold from the shares or cash to be issued upon exercise or vesting of an Award that number of shares or cash having a fair market value equal to the minimum amount required to be withheld, (11) determine whether Awards (other than options or SARs) will be adjusted for dividend equivalents, (12) impose restrictions, conditions or limitations as to the timing and manner of any resales or other subsequent transfers by a participant of any shares issued as a result of or under an Award, and (13) subject to certain limitations, take any other actions deemed necessary or advisable for the administration of the 2007 Stock Plan. All decisions, interpretations and other actions of the Administrator shall be final and binding on all holders of Awards and on all persons deriving their rights therefrom.

Eligibility to Receive Awards. The 2007 Stock Plan provides that performance shares, performance units, restricted stock (including restricted stock units), SARs and non-statutory stock options may be granted to employees, consultants or directors. Incentive stock options may be granted only to our employees. References in this summary to “employment” and “termination of employment” shall, with respect to consultants and outside directors, mean their period of service and the termination of their period of service with us and our subsidiaries.

Share Limits for Awards. In order to satisfy the requirements of Section 162(m) of the Code, the maximum number of shares that may be subject to options and SARs granted to a participant in any fiscal year will equal 400,000 shares, except that the limit will be 1,000,000 shares in the participant’s first fiscal year of service. The maximum number of shares that may be subject to restricted stock, performance shares or performance units granted to a participant in any fiscal year will equal 400,000 shares, except that the limit will be 600,000 shares in the participant’s first fiscal year of service.

Code Section 162(m) Performance Goals. We have designed the 2007 Stock Plan so that it permits us to issue awards that qualify as performance-based under Section 162(m) of the Code. The performance goals applicable to an Award may provide for a targeted level or levels of achievement using one or more of the following measures: (a) revenue, (b) asset management, (c) earnings per share, (d) net income, (e) operating cash flow, (f) operating margins, (g) operating income, (h) return on assets, (i) return on equity, (j) return on sales, (k) total shareholder return, and (l) earnings before interest, taxes, depreciation and amortization, or such similar objectively determinable financial or other measures adopted by the Administrator. The performance goals may be based on absolute target numbers or growth in one or more such categories compared to a prior period or to one or more peer companies or an index of peer companies. The measures which constitute the performance goals may, at the discretion of the Administrator, be based on pro forma numbers and may, as the Administrator specifies, either include or exclude the effect of payment of the Awards under the 2007 Stock Plan and any other of our incentive compensation plans. The Administrator may provide that the attainment of the performance goal shall be measured by appropriately adjusting the evaluation of performance goal performance to exclude (i) any extraordinary non-recurring items as described in Accounting Principles Board Opinion No. 30 and/or in “Management’s Discussion and Analysis of Financial Conditions and Results of Operations” section in our annual report on Form 10-K for the applicable year, or (ii) the effect of any changes in accounting principles affecting our reported business results as a whole or a business unit’s reported results.

No Repricing. The 2007 Stock Plan prohibits repricing of options and SARs, including by way of an exchange for another Award, unless shareholder approval is obtained.

38

Terms and Conditions of Stock Options. Each option granted under the 2007 Stock Plan will be subject to the following terms and conditions:

• Exercise Price. The Administrator sets the exercise price of the shares subject to each option, provided that the exercise price cannot be less than 100% of the fair market value of our common stock on the option grant date. In addition, the exercise price of an incentive stock option must be at least 110% of fair market value if, on the grant date, the participant owns stock possessing more than 10% of the total combined voting power of all classes of our stock or the stock of any of our subsidiaries (a “10% Shareholder”).

• Form of Consideration. The means of payment for shares issued upon exercise of an option is specified in each option agreement. Payment may generally be made in any method permitted by applicable law.

• Exercise of the Option. Each option agreement will specify the term of the option and the date when the option is to become exercisable. The 2007 Stock Plan provides that in no event shall an option granted under the 2007 Stock Plan be exercised more than 7 years after the date of grant. Moreover, in the case of an incentive stock option granted to a 10% Shareholder, the term of the option shall be for no more than 5 years from the date of grant.

• Termination of Employment. If a participant’s employment terminates for any reason (other than death or permanent disability), all options held by such participant under the 2007 Stock Plan expire upon the earlier of such period of time as is set forth in his or her option agreement or the expiration date of the option. In the absence of a specified time in the option agreement, the option will remain exercisable for three months following the participant’s termination. The participant may exercise all or part of his or her option at any time before such expiration to the extent that such option was exercisable at the time of termination of employment.

• Permanent Disability. If a participant is unable to continue employment as a result of permanent and total disability (as defined in the Code), all options held by such participant under the 2007 Stock Plan expire upon the earlier of twelve months after the date of termination of the participant’s employment or the expiration date of the option. The participant may exercise all or part of his or her options at any time before such expiration to the extent that such options were exercisable at the time of termination of employment.

• Death. If a participant dies while employed by us, all options held by such participant under the 2007 Stock Plan expire upon the earlier of twelve months after the participant’s death or the expiration date of the option. The executor or other legal representative of the participant may exercise the participant’s options at any time before such expiration.

• ISO Limitation. If the aggregate fair market value of all shares subject to a participant’s incentive stock option that are exercisable for the first time during any calendar year exceeds $100,000, the excess options shall be treated as non-statutory stock options.

• No Dividend Equivalent Rights. Upon exercise of an option, no adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued.

Stock Appreciation Rights. Each SAR granted under the 2007 Stock Plan will be subject to the following terms and conditions:

• Exercise Price and other Terms. The Administrator sets the exercise price and term of SARs granted under the 2007 Stock Plan, provided that no SAR may have a term of more than 10 years from the date of grant and provided further that the exercise price per share of a SAR cannot be less than 100% of the fair market value per share of our common stock on the SAR grant date.

• Exercise of the SAR. Upon exercise of an SAR, a participant will be entitled to the following amount: (i) the difference between the fair market value of a share on the date of exercise over the exercise price; times (ii) the number of shares with respect to which the SAR is exercised.

• Form of Consideration. Upon the exercise of an SAR, payment may be in cash, shares or a combination thereof.

• Termination of Employment. If a participant’s employment terminates for any reason (other than death or permanent disability), all SARs held by such participant under the 2007 Stock Plan expire upon the

39

earlier of such period of time as is set forth in his or her SAR agreement or the expiration date of the SAR. In the absence of a specified time in the SAR agreement, the SAR will remain exercisable for three months following the participant’s termination. The participant may exercise all or part of his or her SAR at any time before such expiration to the extent that such SAR was exercisable at the time of termination of employment.

• Permanent Disability. If a participant is unable to continue employment as a result of permanent and total disability (as defined in the Code), all SARs held by such participant under the 2007 Stock Plan expire upon the earlier of such period of time as is set forth in his or her SAR agreement or the expiration date of the SAR. In the absence of a specified time in the SAR agreement, the SAR will remain exercisable for 12 months following the participant’s termination. The participant may exercise all or part of his or her SAR at any time before such expiration to the extent that such SAR was exercisable at the time of termination of employment.

• Death. If a participant dies while employed by us, all SARs held by such participant under the 2007 Stock Plan expire upon the earlier of such period of time as is set forth in his or her SAR agreement or the expiration date of the SAR. In the absence of a specified time in the SAR agreement, the SAR will remain exercisable for 12 months following the participant’s death. The executor or other legal representative of the participant may exercise the participant’s SAR at any time before such expiration.

Restricted Stock. Each share of restricted stock granted under the 2007 Stock Plan will be subject to the following terms and conditions:

• Restrictions. The Administrator sets the conditions upon which the grant, vesting or issuance of restricted stock is conditioned. Such conditions will typically be based principally or solely on continued provision of services but may include a performance-based component.

• Restricted Stock Units. Restricted stock may also be granted in the form of restricted stock units. No right to vote or receive dividends or any other rights as a shareholder will exist with respect to restricted stock units or the cash payable thereunder.

Performance Shares. Each performance share granted under the 2007 Stock Plan will be subject to the following terms and conditions:

• Grant. Performance shares will be granted in the form of units to acquire shares of our common stock. Each unit will be the equivalent of one share of our common stock for purposes of determining the number of shares subject to an Award. Until the shares are issued, no right to vote or receive dividends or any other rights as a shareholder will exist with respect to the performance units.

• Performance Milestones. The Administrator sets the conditions upon which the grant or vesting of performance shares is conditioned. Such conditions will typically be based principally or solely on achievement of performance-based milestones but may include a service-based component.

Performance Units. Each performance unit granted under the 2007 Stock Plan will be subject to the following terms and conditions:

• Grant. Performance units will be granted in the form of units to acquire shares of our common stock. Each unit will be the cash equivalent of one share of our common stock, and will be settled in cash in an amount equivalent to the fair market value of the underlying shares as of the vesting date. No right to vote or receive dividends or any other rights as a shareholder will exist with respect to performance units or the cash payable thereunder.

• Performance Milestones. The Administrator sets the conditions upon which the grant or vesting of performance units is conditioned. Such conditions will typically be based principally or solely on achievement of performance-based milestones but may include a service-based component.

Compliance with Code Section 409A. To the extent that the Administrator determines that any Award granted under the 2007 Stock Plan is subject to Section 409A of the Code, it is intended that the 2007 Stock Plan

40

incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code and that the Award Agreement and the 2007 Stock Plan be interpreted and construed in compliance with Section 409A and the Treasury Regulations and other interpretive guidance issued under Section 409A.

Material Federal Income Tax Consequences

The U.S. federal income tax consequences of awards under the 2007 Stock Plan are summarized below. The information set forth below is a summary only and does not purport to be complete. The information is based upon current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local, foreign and other tax consequences of the grant, exercise or settlement of an Award or the disposition of shares of our common stock acquired as a result of an Award. The 2007 Stock Plan is not qualified under the provisions of Section 401(a) of the Internal Revenue Code, and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974.

Nonstatutory Stock Options. The grant of a non-statutory stock option with an exercise price equal to the fair market value of our stock on the date of grant has no immediate federal income tax effect. The participant will not recognize any taxable income and we will not receive a tax deduction.

When the participant exercises the option, the participant will recognize ordinary income in an amount equal to the excess of the fair market value of the shares of our common stock on the date of exercise over the exercise price. If the participant is employed by the Company or any of its subsidiaries, we are required to withhold tax on the amount of income recognized. We will receive a tax deduction equal to the amount of income recognized.

When the participant sells the shares of our common stock obtained from exercising a non-statutory stock option, any gain or loss will be taxed as a capital gain or loss (long-term or short-term, depending on how long the shares have been held). Certain additional rules apply if the exercise price for an option is paid in shares previously owned by the participant.

Incentive Stock Options. When a participant is granted an incentive stock option, or when the participant exercises the incentive stock option, the participant will generally not recognize taxable income (except for purposes of the alternative minimum tax) and we will not receive a tax deduction.

If the participant holds the shares of our common stock for at least two years from the date of grant, and one year from the date of exercise, then any gain or loss will be treated as long-term capital gain or loss. If, however, the shares are disposed of during this period, the option will be treated as a non-statutory stock option, and the participant will recognize taxable income equal to the lesser of the fair market value of the shares on the exercise date minus the exercise price or the amount realized on disposition minus the exercise price. Any gain in excess of the taxable income portion will be taxable as long-term or short-term capital gain. We will only receive a tax deduction if the shares are disposed of during this period. The deduction will be equal to the amount of taxable income the participant recognizes.

Stock Appreciation Rights. Where SARs are granted with an exercise price equal to the fair market value of our stock on the grant date, the participant will recognize taxable income upon the exercise of the right equal to the fair market value of the stock or cash received upon such exercise. If the participant receives shares of our stock, then upon sale of those shares any subsequent gain or loss will be taxed as a capital gain or loss (long-term or short-term, depending on how long the shares have been held).

If the participant is employed by the Company or any of its subsidiaries, we are required to withhold tax on the amount of taxable income recognized. We will generally be entitled to a tax deduction equal to the taxable income realized by the participant.

Restricted Stock. Generally, a participant who receives restricted stock will recognize taxable income at the time the stock is received equal to the excess, if any, of the fair market value of the stock received over any amount paid by the participant in exchange for the stock. If, however, the stock is not vested when it is received, the participant generally will not recognize taxable income until the stock becomes vested, at which time the participant will recognize

41

taxable income equal to the excess, if any, of the fair market value of the stock on the date it becomes vested over any amount paid by the participant in exchange for the stock. A participant may, however, file an election with the Internal Revenue Service within 30 days of his or her receipt of the restricted stock award to recognize taxable income, as of the date the participant receives the award, equal to the excess, if any, of the fair market value of the stock on the date the award is granted over any amount paid by the participant in exchange for the stock.

The participant’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from restricted stock awards will be the amount paid for such shares plus any taxable income recognized either when the stock is received or when the stock becomes vested.

If the participant is employed by the Company or any of its subsidiaries, we are required to withhold tax on the amount of taxable income recognized. We will generally be entitled to a tax deduction equal to the taxable income realized by the participant and will also be entitled to a deduction for dividends or dividend equivalents paid to the participant (if any) on stock that has not vested.

Restricted Stock Units, Performance Shares and Performance Units. Generally, the participant who receives a restricted stock unit, performance share or performance unit structured to conform to the requirements of Section 409A of the Code (or qualify for an exception thereto) will recognize taxable income at the time the stock or cash is delivered equal to the excess, if any, of the fair market value of the shares of our common stock or the cash received over any amount paid by the participant. If the restricted stock unit, performance share or performance unit does not conform to the requirements of Section 409A of the Code (or qualify for an exception thereto) then, in addition to the tax treatment described above, the participant will owe an additional 20% tax and interest on any taxes owed.

If the participant receives shares of our stock in settlement of a restricted stock unit, performance share or performance unit, then upon sale of those shares any subsequent gain or loss will be taxed as a capital gain or loss (long-term or short-term depending on how long the shares have been held).

If the participant is employed by the Company or any of its subsidiaries, we are required to withhold tax on the amount of taxable income recognized. We will generally be entitled to a tax deduction equal to the taxable income realized by the participant.

Section 409A. The American Jobs Creation Act of 2004 added Section 409A to the Code. The Internal Revenue Service has so far issued only limited guidance on the interpretation of this new law. Section 409A covers most programs that defer the receipt of compensation to a succeeding year. It provides strict rules for elections to defer (if any) and for timing of payouts. There are significant penalties placed on the recipient of deferred compensation, including employees, consultants and directors, for failure to comply with Section 409A. However, it does not impact our ability to deduct deferred compensation. Section 409A of the Code does not apply to incentive stock options, non-statutory stock options and SARs (that are not discounted) and restricted stock (provided there is no deferral of income beyond the vesting date). Section 409A may apply to restricted stock units, performance units and performance shares.

Section 162(m). As described above, awards may qualify as “performance-based compensation” under Section 162(m) of the Code in order to preserve the Company’s federal income tax deduction with respect to annual compensation required to be taken into account under Section 162(m) that is in excess of $1 million and paid to certain executive officers. To qualify, options and other awards must be granted by a committee consisting solely of two or more “outside directors” (as defined under applicable regulations) and satisfy the limit on the total number of shares of our common stock that may be awarded to any one participant during any fiscal year. In addition, for awards other than options and SARs (that are not discounted) to qualify, the grant, issuance, vesting or retention of the award must be contingent upon satisfying one or more of the performance criteria, as established and certified by a committee consisting solely of two or more “outside directors”.

Recommendation by the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE “FOR” THE PROPOSED AMENDMENT TO THE RADISYS CORPORATION 2007 STOCK PLAN.

42

PROPOSAL 4: TO APPROVE THE AMENDED AND RESTATED RADISYS CORPORATION

LONG-TERM INCENTIVE PLAN

Our shareholders approved the RadiSys Corporation Long-Term Incentive Plan (as it may be amended from time to time, the “LTIP”) in May 2008. The Compensation and Development Committee anticipated implementing the LTIP in 2008 following its approval by shareholders.

The purposes of the LTIP are to pay long-term incentive compensation to executive officers and key employees designated to participate in the LTIP, to increase shareholder value and the success of the Company by motivating LTIP participants to excel beyond what is customary in their performance and to achieve substantially challenging business objectives that deliver significant shareholder value. In addition, the Board of Directors believes that the awards under the LTIP are a highly effective way to retain executive officers and key participating employees through potential share value appreciation and equity accumulation.

The LTIP awards are performance based, and participants are only eligible to receive these awards if certain financial or strategic metrics meet or exceed threshold targets established by our Compensation and Development Committee. Because of the dramatic change in the global economic environment, it became difficult to establish longer-range corporate performance targets at the end of 2008, and our Compensation and Development Committee decided to delay the start of the LTIP program.

On September 30, 2009, the Compensation and Development Committee approved certain amendments to the LTIP intended to address the changes in the global economic environment and our business and granted the first tranche of awards to participants on October 1, 2009.

In February 2010, to further address limitations in the LTIP caused by the deferral in granting awards and to provide more flexibility to structure performance goals in a manner responsive to current economic circumstances and our strategic plan, our Board of Directors approved certain amendments to the LTIP, which are subject to the shareholder approval described below and are reflected in the form of Amended and Restated RadiSys Corporation Long–Term Incentive Plan attached to this document as Appendix C.

The amendments revise the definition of “Performance Goals” to (i) eliminate prescriptive defined terms and (ii) allow for performance measures to be calculated on a consolidated and on a per share basis and to be based on pro-forma, adjusted or non-GAAP financial measures, which would be better aligned with our strategic plan.

To address the delay in implementing the LTIP, the prior amendments eliminated the limitation on the beginning of the first performance period under the LTIP, which previously required that the first performance period begin no later than January 1, 2009, and the current amendments eliminate the limitation on the beginning of the last performance period under the LTIP, which previously required that the last performance period under the LTIP begin no later than January 1, 2011.

Finally, the amendments will restate the LTIP to incorporate the aforementioned amendments and all prior amendments.

Certain provisions of the LTIP are summarized below. The complete text of the proposed amendment and the amended and restated version of the LTIP, marked to show the proposed amendments, is attached to this document as Appendix C.

Description of the Amended and Restated RadiSys Corporation Long-Term Incentive Plan

The following paragraphs provide a summary of the principal features of the LTIP as proposed to be amended and restated. This summary does not purport to be complete and is subject to, and qualified in its entirety by, the provisions of the LTIP as proposed to be amended and restated, which is attached hereto as Appendix C. Capitalized terms used herein and not defined shall have the meanings set forth in the LTIP.

43

Purpose. The purpose of the LTIP is to pay long-term incentive compensation to those executive officers and key employees designated to participate in the LTIP and to increase shareholder value and the success of the Company by motivating LTIP participants to excel beyond what is customary in their performance and to achieve substantially challenging business objectives that deliver significant shareholder value. The LTIP provides for the grant of awards payable in shares of common stock or cash to reward and provide incentives to the participants and to retain them through potential share value appreciation and equity accumulation.

Awards. The LTIP provides for the grant of awards (the “Awards”) payable in shares of common stock or cash upon the achievement of performance goals set by our Compensation and Development Committee. Performance goals will be set with respect to each performance period, which will generally be a period of three consecutive fiscal years or any other period selected by the Committee.

Stock Subject to the LTIP. The number of shares of our common stock initially reserved for issuance under the LTIP was 2,000,000 shares. The first tranche of Awards for the three-year performance period beginning in October 1, 2009 has been made to participants, which provided for total payments of 537,300, 716,400 and 895,500 shares in the aggregate upon attainment of the threshold, target and maximum levels of performance, respectively. If an Award is forfeited or if any portion of an Award is not distributed, the forfeited or undistributed shares will remain available for future grants under the LTIP. The LTIP does not permit shares withheld for taxes to be added back to the shares available for future grants.

In order to satisfy the requirements of Code Section 162(m), no participant will receive in any one fiscal year grants of Awards covering an aggregate of more than 500,000 shares and, if such Awards are denominated in cash value, no more than $1,000,000 may be subject to such Awards granted to any one participant during any one fiscal year.

Administration. The LTIP is administered by our Compensation and Development Committee, or its sub-committee. Subject to the provisions of the LTIP, the Compensation and Development Committee has the authority to: (a) select the employees to whom Awards are granted, (b) adopt target awards and payout formulas under the LTIP for a given performance period, (c) construe and interpret the terms of the LTIP, and determine eligibility and the amount, manner, time and form of payment of Awards, (d) prescribe forms and procedures for purposes of participation and distribution of Awards, (e) prescribe, amend and rescind rules relating to the LTIP, including rules relating to sub-plans established for the purpose of qualifying for preferred tax treatment under foreign laws, and (f) take any other actions it deems necessary or desirable for the administration of the LTIP. All decisions, interpretations and other actions of the Compensation and Development Committee will be final and binding on all holders of Awards and on all persons deriving their rights therefrom.

Eligibility to Receive Awards. Our Compensation and Development Committee will designate the employees eligible to participate in the LTIP for a given performance period. The eligible employees are generally expected to include our executive officers who are subject to Section 16 of the Securities Exchange Act of 1934 and other key employees. Except as provided below, to be eligible to receive a payment under the LTIP, a participant must be actively employed on the last day of the quarter for which the Compensation and Development Committee certifies that the performance goal for the performance period has been achieved.

Code Section 162(m) Performance Goals. Awards under the LTIP are intended to be eligible to qualify as performance-based under Code Section 162(m). The performance goals applicable to an Award may provide for a targeted level or levels of achievement based on one or more of the following measures: (a) annual revenue, (b) cash position, (c) earnings per share, (d) net income, (e) operating cash flow, (f) operating margins, (g) operating income, (h) return on assets, (i) return on equity, (j) return on sales, and (k) total stockholder return or such similar objectively determinable financial or other measures as may be adopted by our Compensation and Development Committee. Performance measures may be calculated on a consolidated or per share basis and may be based on pro-forma, adjusted or non-GAAP financial measures.

Performance Goal and Incentive Level Determination. Our Compensation and Development Committee, in its sole discretion, will establish in writing the performance goals and target awards for each participant for a

44

performance period and may establish multiples or percentages of target awards that may be earned. Each of the target awards will represent the amount of cash or the number of shares that can be earned by the participant during the performance period, based on the performance goals achieved and the level of achievement for such period as determined by the Compensation and Development Committee. The performance goals and target awards for a performance period will be set on or prior to the latest possible date that will not jeopardize an Award’s qualification under Code Section 162(m) to the extent such Awards are intended to qualify for deductibility.

Payout Formula Determination. On the grant date, the Compensation and Development Committee will establish a payout formula and payout determination dates for purposes of determining the Award payable to a participant upon the Committee’s certification of achievement of a performance goal.

Payout Determination and Award Payment. On each payout determination date, the Compensation and Development Committee will certify in writing the extent to which the performance goals applicable to each participant for the performance period were achieved or exceeded. The Award for each participant will be determined by applying the payout formula to the actual level of performance that has been certified by the Committee. The Committee, in its sole discretion, may eliminate or reduce the Award payable to any participant.

Awards will be distributed to participants in shares or cash as soon as practicable following the determination and written certification of the Award for a quarter during a performance period, but in any event no later than the date that is two and one-half months following the last day of the Company’s fiscal year coinciding with or next following the last day of the quarter of a performance period. If a participant dies prior to the date the Award would be distributed, such Award will be paid to the personal representative of the participant’s estate or the person(s) to whom the Award is transferred pursuant to the participant’s will or in accordance with the laws of descent and distribution.

Our Compensation and Development Committee may defer payment of Awards as the Committee, in its discretion, determines to be necessary to preserve the deductibility of such amounts under Code Section 162(m). In addition, the Committee, in its sole discretion, may permit a participant to defer receipt of the payment of shares or cash under the LTIP, provided that such deferral elections will be made in accordance with Code Section 409A.

Termination of Employment. Upon a participant’s termination of employment prior to the last day of a quarter for which the Committee certifies that the performance goal for the performance period has been achieved, Awards will be paid as follows:

Death or Disability. If a participant’s employment terminates as a result of the participant’s death or disability prior to the last day of a quarter for which the Committee certifies that the performance goal for the performance period has been achieved, the participant will be entitled to receive a pro-rata Award with respect to such performance goal. The Award will be payable as soon as practicable following the determination and certification of the Award for the performance period, but in any event no later than the date that is two and one half months following the end of the fiscal year coinciding with or next following the last day of the quarter for which achievement of the performance goal is certified.

Termination without Cause. If a participant’s employment is terminated without cause prior to the last date of a quarter for which the Committee certifies that the performance goal for the performance period has been achieved, the participant will be entitled to receive a pro-rata Award with respect to such performance goal. The pro-rata Award will be distributed to the participant as soon as practicable following the determination and written certification of the Award for the performance period, but in any event no later than the date that is two and one-half months following the last day of the fiscal year coinciding with or next following the last day of the quarter for which achievement of the performance goal is certified.

Change of Control. If a participant has an employment, change of control or other agreement that provides for the effect of a change of control on such participant’s Awards, then that agreement will control. In all other cases,

45

unless the Compensation and Development Committee shall otherwise expressly provide in the agreement relating to an Award, in the event of a potential change of control, the Compensation and Development Committee will determine whether a performance goal has been achieved as of the last day of the prior quarter, and if such achievement equals or exceeds 50% of the performance goal corresponding to the threshold award level, then, in the event of a change of control, the participant shall be entitled to receive a portion of his or her Award as follows: if a participant has received all or any portion of his or her Award for a performance period prior to a change of control, no further Awards shall be payable to such participant, and if a participant has not received any portion of his or her Award for a performance period prior to a change of control, the participant will be entitled to receive a pro-rata Award based on his or her target award, provided the participant is actively employed by the Company immediately prior to such change of control. In the event of a potential change of control and if the achievement determined by the Compensation and Development Committee above is less than 50% of the performance goal corresponding to the threshold award level, then, in the event of a change of control, the Compensation and Development Committee may in its discretion provide for payment of a portion of such Award in such amounts as the Committee may determine in its sole discretion, provided any Participant receiving such Award is actively employed by the Company immediately prior to such change of control. A “potential change of control” will occur if the Company enters into an agreement, the consummation of which would result in the occurrence of a change of control, any person (including the Company) publicly announces an intention to take or to consider taking actions which if consummated would constitute a change of control or our Board of Directors adopts a resolution stating that a potential change of control exists.

Other Termination. If a participant’s employment is terminated for any reason not described above prior to the last day of the quarter for which the Committee certifies that the performance goal for the performance period has been achieved, the participant will forfeit the right to receive any Award with respect to such quarter or any future quarters in that performance period. Upon a participant’s termination for cause following the last day of the quarter for which achievement of the performance goal is certified but prior to the date on which the participant’s Award is paid, such participant will forfeit the right to receive such Award.

Term. The LTIP became effective as of the date it was approved by our shareholders in May 2008.

Adjustments Upon Changes in Capitalization. In the event that our capital stock is changed by reason of any stock split, reverse stock split, stock dividend, combination or reclassification of our common stock or any other increase or decrease in the number of issued shares of common stock effected without receipt of consideration by us, appropriate proportional adjustments shall be made in the number and class of shares subject to the LTIP, the individual fiscal year limits applicable to Awards that are denominated in shares, and the number and class of shares of stock subject to any Award outstanding under the LTIP. Any such adjustment shall be made by our Compensation and Development Committee, whose determination shall be conclusive.

Nonassignment. The rights of a participant under the LTIP will not be assignable or transferable by the participant except by will or the laws of intestacy.

Amendment and Termination of the LTIP. Our Compensation and Development Committee may amend, alter, suspend or terminate the LTIP at any time. Shareholder approval will be required for any amendment to the extent necessary to comply with applicable law or Nasdaq listing rules. In addition, no amendment, alteration, suspension or termination will impair any payments to participants made prior to such amendment, alteration, suspension or termination unless the Committee has determined that such amendment or modification is in the best interests of all persons to whom Awards have been granted.

Compliance with Code Section 409A. The LTIP and the Awards granted thereunder are intended to meet the “short-term deferral” exception to the provisions of Code Section 409A and Treasury regulations issued thereunder or to otherwise comply with Code Section 409A and the Treasury regulations and guidance issued thereunder. Notwithstanding any provision of the LTIP to the contrary, the LTIP will be interpreted and construed consistent with this intent. Notwithstanding the foregoing, we will not be required to assume any increased economic burden in connection therewith.

46

Material Federal Income Tax Consequences

The U.S. federal income tax consequences of awards under the LTIP are summarized below. The information set forth below is a summary only and does not purport to be complete. The information is based upon current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local, foreign and other tax consequences of the grant, exercise or settlement of an Award or the disposition of shares of our common stock acquired as a result of an Award. The LTIP is not qualified under the provisions of Code Section 401(a).

In general, upon becoming a participant in the LTIP with respect to a performance period, an employee will not be subject to taxation and we will not receive a deduction. If the Award conforms to the requirements of Code Section 409A or qualifies for an exception thereto, a participant will recognize taxable income at the time the stock or cash is delivered with respect to the Award, equal to the fair market value of the shares of our common stock or the cash received. If the Award does not conform to the requirements of Code Section 409A (or qualify for an exception thereto) then, in addition to the tax treatment described above, the participant will owe an additional 20% tax and interest on any taxes owed.

If the participant receives shares of our stock in settlement of an Award, then upon sale of those shares any subsequent gain or loss will be taxed as a capital gain or loss (long-term or short-term depending on how long the shares have been held).

If the participant is employed by the Company or any of its subsidiaries, we are required to withhold tax on the amount of taxable income recognized. We will generally be entitled to a tax deduction equal to the taxable income realized by the participant.

Section 409A. The American Jobs Creation Act of 2004 added Section 409A to the Code. Code Section 409A covers most programs that defer the receipt of compensation to a succeeding year. It provides strict rules for elections to defer (if any) and for timing of payouts. There are significant penalties placed on the recipient of deferred compensation, including employees, for failure to comply with Code Section 409A. However, it does not impact our ability to deduct deferred compensation. Awards granted under the LTIP are intended to be exempt from the requirements of Code Section 409A as short term deferrals.

Section 162(m). As described above, Awards are intended to be eligible to qualify as “performance-based compensation” under Code Section 162(m) in order to preserve our federal income tax deduction with respect to annual compensation required to be taken into account under Code Section 162(m) that is in excess of $1,000,000 and paid to certain executive officers. The first tranche of Awards under the LTIP were not intended to so qualify. To qualify, Awards must be granted by a committee consisting solely of two or more “outside directors” (as defined under applicable regulations) and satisfy the limit on the total number of shares of our common stock or the total cash value that may be awarded to any one participant during any fiscal year. In addition, the grant, issuance, vesting or retention of the Award must be contingent upon satisfying one or more of the performance criteria, as established and certified by a committee consisting solely of two or more “outside directors.”

Inapplicability of ERISA

Based upon current law and published interpretations, we do not believe that the LTIP is subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended.

Shareholder Approval

Shareholder approval is required for the amended and restated LTIP. If shareholders do not approve the amended and restated LTIP, the Company will utilize the existing LTIP that has been previously approved by shareholders.

47

THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE “FOR” THE PROPOSED APPROVAL OF THE RADISYS CORPORATION AMENDED AND RESTATED LONG–TERM INCENTIVE PLAN.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

None.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

None.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 requires our directors, executive officers and persons who own more than 10% of our outstanding common stock to file with the SEC reports of changes in ownership of the common stock of the Company held by such persons. Officers, directors and greater than 10% shareholders are also required to furnish the Company with copies of all forms they file under this regulation. To the Company’s knowledge, based solely on a review of the copies of the reports received by the Company during and with respect to fiscal 2009 and on written representations of certain reporting persons, no director, executive officer or beneficial owner of more than 10% of the outstanding common stock of the Company failed to file on a timely basis reports required by Section 16(a) of the Securities Exchange Act of 1934.

HOUSEHOLDING OF MATERIALS

We participate, and some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy materials. This means that only one copy of the Notice may have been sent to multiple shareholders in the same household. The Company will promptly deliver a separate copy of the Notice or this Proxy Statement and its annual report to any shareholder upon request by writing or calling the Company at the following address or phone number: RadiSys Corporation, 5445 NE Dawson Creek Drive, Hillsboro, Oregon 97124, Attention: Investor Relations or by calling (503) 615-7797. Any shareholder who wants to receive separate copies in the future, or who is currently receiving multiple copies and would like to receive only one copy for his or her household, should contact his or her bank, broker, or other nominee record holder, or contact the Company at the above address and phone number.

SHAREHOLDER PROPOSALS FOR 2011 ANNUAL MEETING

Our bylaws require shareholders to give the Company advance notice of any proposal or director nomination to be submitted at an annual meeting of shareholders. A copy of the relevant provisions of the bylaws will be provided to any shareholder upon written request to 5445 NE Dawson Creek Drive, Hillsboro, Oregon 97124, Attention: Corporate Secretary. The bylaws prescribe the information to be contained in any such notice. To be timely, a shareholder’s notice must be delivered to or mailed and received by the Corporate Secretary not less than 50 days nor more than 75 days before the annual meeting, provided, however, that if less than 65 days’ notice or prior public disclosure of the date of the meeting is given to shareholders, notice by the shareholder, to be timely, must be received by the Corporate Secretary not later than the close of business on the tenth day following the earlier of the day on which the notice of the date of the meeting was mailed or public disclosure

48

was made. The Company’s 2011 annual meeting of shareholders is expected to be held on or about May 17, 2011, although this may change in the discretion of our board of directors. Any notice relating to a shareholder proposal for the 2011 annual meeting, to be timely, must be received by the Company between March 3, 2011 and March 28, 2011. Shareholders wishing to submit proposals in compliance with Rule 14a-8 of the Securities Exchange Act of 1934, for inclusion in the Company’s proxy statement for the 2011 annual meeting of shareholders must deliver their proposals to our executive offices not later than December 23, 2010, which is 120 days before the anticipated April 22, 2011 mailing date of the proxy statement for the 2011 annual meeting.

DISCRETIONARY AUTHORITY

Although the Notice of the annual meeting of shareholders provides for transaction of any other business that properly comes before the meeting, the Board of Directors has no knowledge of any matters to be presented at the meeting other than the matters described in this proxy statement. The enclosed proxy, however, gives discretionary authority to the proxy holders to vote in accordance with their judgment if any other matters are presented.

3. Stock Subject to the Plan. Subject to the provisions of Section 16 of the Plan, the maximum aggregate number of Shares which may be issued under the Plan is [3,200,000] 3,700,000 Shares.

Any Shares subject to Options or SARs shall be counted against the numerical limits of this Section 3 as one share for every share subject thereto. Any Shares or units subject to Restricted Stock, Performance Shares or Performance Units with a per share or per unit purchase price lower than 100% of Fair Market Value on the date of grant shall be counted against the numerical limits of this Section 3 as two Shares for every one Share subject thereto and, if returned to the Plan pursuant to the last paragraph of this Section, shall be returned to the Plan as two Shares for every one Share returned to the Plan.

The Shares may be authorized, but unissued, or reacquired Common Stock.

If an Award expires or becomes unexercisable without having been exercised in full, or, with respect to Restricted Stock, Performance Shares or Performance Units is forfeited to or repurchased by the Company, the unpurchased Shares (or for Awards other than Options and SARs, the forfeited or repurchased Shares) which were subject thereto shall become available for future grant or sale under the Plan (unless the Plan has terminated). With respect to SARs, when a stock-settled SAR is exercised, the Shares subject to the SAR Award Agreement shall be counted against the number of Shares available for future grant or sale under the Plan, regardless of the number of Shares used to settle the SAR upon exercise. Shares that have actually been issued under the Plan under any Award shall not be returned to the Plan and shall not become available for future distribution under the Plan; provided, however, if unvested Shares of Restricted Stock, Performance Shares or Performance Units are repurchased by the Company or are forfeited to the Company, such Shares shall become available for future grant under the Plan. Shares used to pay the exercise price of an Option and Shares used to satisfy tax withholding obligations shall not become available for future grant or sale under the Plan.

4. Administration of the Plan.

(a) Procedure.

(i) Multiple Administrative Bodies. The Plan may be administered by different Committees with respect to different groups of Service Providers.

(ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan shall be administered by a Committee of two or more “outside directors” within the meaning of Section 162(m) of the Code.

(iii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder shall be structured to satisfy the requirements for exemption under Rule 16b-3.

(iv) Other Administration. Other than as provided above, the Plan shall be administered by (A) the Board or (B) a Committee, which committee shall be constituted to satisfy Applicable Laws.

(b) Powers of the Administrator. Subject to the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion:

(i) to determine the Fair Market Value of the Common Stock, in accordance with Section 2(r) of the Plan;

(ii) to select the Service Providers to whom Awards may be granted hereunder;

(iii) to determine whether and to what extent Awards or any combination thereof, are granted hereunder;

(iv) to determine the number of Shares to be covered by each Award granted hereunder;

(v) to approve forms of agreement for use under the Plan;

(vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and conditions include, but are not limited to, the exercise price, the time or times when Options or SARs may be exercised or other Awards vest (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or the shares of Common Stock relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine;

(vii) to construe and interpret the terms of the Plan and Awards;

(viii) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred tax treatment under foreign tax laws;

(ix) to modify or amend each Award (subject to Section 9(c) and Section 18(c) of the Plan), including the discretionary authority to extend the post-termination exercisability period of Options and SARs longer than is otherwise provided for in the Plan;

(x) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator;

(xi) to allow Participants to satisfy all or part of their withholding tax obligations by electing to have the Company withhold from the Shares or cash to be issued upon exercise or vesting of an Award that number of Shares or cash having a Fair Market Value equal to the minimum amount required to be withheld (but no more). The Fair Market Value of any Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares or cash withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable;

B-4

(xii) to determine the terms and restrictions applicable to Awards;

(xiii) to determine whether Awards (other than Options or SARs) will be adjusted for Dividend Equivalents;

(xiv) to impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by a Participant or other subsequent transfers by a Participant of any Shares issued as a result of or under an Award, including without limitation, (A) restrictions under an insider trading policy, and (B) restrictions as to the use of a specified brokerage firm for such resales or other transfers; and

(xv) to make all other determinations deemed necessary or advisable for administering the Plan.

(c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations shall be final and binding on all Participants and any other holders of Awards.

5. Eligibility. Performance Shares, Performance Units, Restricted Stock, Stock Appreciation Rights, and Nonstatutory Stock Options may be granted to Service Providers. Incentive Stock Options may be granted only to Employees.

6. No Employment Rights. Neither the Plan nor any Award shall confer upon a Participant any right with respect to continuing the Participant’s employment with the Company or its Subsidiaries, nor shall they interfere in any way with the Participant’s right or the Company’s or Subsidiary’s right, as the case may be, to terminate such employment at any time, with or without cause or notice.

7. Code Section 162(m) Provisions.

(a) Option and SAR Annual Share Limit. The maximum number of Shares that may be subject to Options and Stock Appreciation Rights granted to a Participant in any Fiscal Year shall equal 400,000 Shares; provided, however, that such limit shall be 1,000,000 Shares in the Participant’s first Fiscal Year of Company service.

(b) Restricted Stock, Performance Shares and Performance Units Annual Limit. The maximum number of Shares that may be subject to Restricted Stock, Performance Shares or Performance Units granted to a Participant in any Fiscal Year shall equal 400,000 Shares; provided, however, that such limit shall be 600,000 Shares in the Participant’s first Fiscal Year of Company service.

(c) Section 162(m) Performance Restrictions. For purposes of qualifying grants of Restricted Stock, Performance Shares or Performance Units as “performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon the achievement of Performance Goals. The Performance Goals shall be set by the Administrator on or before the latest date permissible to enable the Restricted Stock, Performance Shares or Performance Units to qualify as “performance-based compensation” under Section 162(m) of the Code. In granting Restricted Stock, Performance Shares or Performance Units which are intended to qualify under Section 162(m) of the Code, the Administrator shall follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Section 162(m) of the Code (e.g., in determining the Performance Goals).

(d) Changes in Capitalization. The numerical limitations in Section 7(a) and (b) shall be adjusted proportionately in connection with any change in the Company’s capitalization as described in Section 16(a).

8. Term of Plan.

The Plan shall continue in effect for a term of 10 years after the Effective Date.

B-5

9. Stock Options.

(a) Term. The term of each Option shall be stated in the Notice of Grant; provided, however, that the term shall be no longer than 7 years from the date of grant. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than 10 percent of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be no longer than five years from the date of grant.

(b) Option Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be determined by the Administrator and shall be no less than 100% of the Fair Market Value per Share on the date of grant; provided, however, in the case of an Incentive Stock Option granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than 10 percent of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant.

(c) No Repricing. Subject to Section 16, the exercise price for an Option may not be reduced without the consent of the Company’s stockholders. This shall include, without limitation, a repricing of the Option as well as an Option exchange program whereby the Participant agrees to cancel an existing Option in exchange for an Option, SAR or other Award.

(d) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator shall fix the period within which the Option may be exercised and shall determine any conditions which must be satisfied before the Option may be exercised. In so doing, the Administrator may specify that an Option may not be exercised until the completion of a service period or until performance milestones are satisfied.

(e) Form of Consideration. The Administrator shall determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator shall determine the acceptable form of consideration at the time of grant. Subject to Applicable Laws, such consideration may consist entirely of:

(i) cash;

(ii) check;

(iii) other Shares which (A) in the case of Shares acquired upon exercise of an Option, have been owned by the Participant for more than six months on the date of surrender, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised;

(iv) delivery of a properly executed exercise notice together with such other documentation as the Administrator and the broker, if applicable, shall require to effect an exercise of the Option and delivery to the Company of the sale proceeds required to pay the exercise price;

(v) subject to compliance with Code Section 409A, a reduction in the amount of any Company liability to the Participant;

(vi) any combination of the foregoing methods of payment; or

(vii) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Law; provided, however, that in no case will loans be permitted as consideration for exercising an Option hereunder.

(f) Exercise of Option; Rights as a Stockholder. Any Option granted hereunder shall be exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Option Agreement.

An Option may not be exercised for a fraction of a Share.

An Option shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and

B-6

(ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Participant. Until the stock certificate evidencing such Shares is issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the optioned stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such stock certificate promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 16 of the Plan.

Exercising an Option in any manner shall decrease the number of Shares thereafter available for sale under the Option, by the number of Shares as to which the Option is exercised.

(g) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s death or Disability, the Participant may exercise his or her Option within such period of time as is specified in the Option Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three months following the Participant’s termination. If, on the date of termination, the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Participant does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(h) Disability. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option for 12 months following the Participant’s termination (but in no event may the Option be exercised later than the expiration of the term of such Option as set forth in the Option Agreement). If, on the date of termination, the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Participant does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(i) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised for 12 months following the Participant’s death (but in no event may the Option be exercised later than the expiration of the term of such Option as set forth in the Option Agreement), by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

(j) ISO $100,000 Rule. Each Option shall be designated in the Notice of Grant as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designations, to the extent that the aggregate Fair Market Value of Shares subject to a Participant’s Incentive Stock Options granted by the Company, any Parent or Subsidiary, which becomes exercisable for the first time during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 9(j), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the time of grant.

10. Stock Appreciation Rights.

(a) Grant of SARs. Subject to the terms and conditions of the Plan, SARs may be granted to Participants at any time and from time to time as shall be determined by the Administrator, in its sole discretion. The Administrator shall have complete discretion to determine the number of SARs granted to any Participant.

B-7

(b) Exercise Price and other Terms. Subject to Section 7(a) of the Plan, the Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms and conditions of SARs granted under the Plan; provided, however, no SAR may have a term of more than 10 years from the date of grant, and provided further, the exercise price per Share of a SAR shall be no less than 100% of the Fair Market Value per Share on the date of grant of the SAR. The exercise price for the Shares or cash to be issued pursuant to an already granted SAR may not be changed without the consent of the Company’s stockholders. This shall include, without limitation, a repricing of the SAR as well as a SAR exchange program whereby the Participant agrees to cancel an existing SAR in exchange for an Option, SAR or other Award.

(c) Payment of SAR Amount. Upon exercise of a SAR, a Participant shall be entitled to receive payment from the Company in an amount determined by multiplying:

(i) the difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times

(ii) the number of Shares with respect to which the SAR is exercised.

(d) Payment Upon Exercise of SAR. At the discretion of the Administrator, payment for a SAR may be in cash, Shares or a combination thereof.

(e) SAR Agreement. Each SAR grant shall be evidenced by an Award Agreement that shall specify the exercise price, the term of the SAR, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, shall determine.

(f) Expiration of SARs. A SAR granted under the Plan shall expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement.

(g) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s death or Disability, the Participant may exercise his or her SAR within such period of time as is specified in the SAR Award Agreement to the extent that the SAR is vested on the date of termination (but in no event later than the expiration of the term of such SAR as set forth in the SAR Award Agreement). In the absence of a specified time in the SAR Award Agreement, the SAR shall remain exercisable for three months following the Participant’s termination. If, on the date of termination, the Participant is not vested as to his or her entire SAR, the Shares covered by the unvested portion of the SAR shall revert to the Plan. If, after termination, the Participant does not exercise his or her SAR within the time specified by the Administrator, the SAR shall terminate, and the Shares covered by such SAR shall revert to the Plan.

(h) Disability. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her SAR within such period of time as is specified in the SAR Award Agreement to the extent the SAR is vested on the date of termination (but in no event later than the expiration of the term of such SAR as set forth in the SAR Award Agreement). In the absence of a specified time in the SAR Award Agreement, the SAR shall remain exercisable for 12 months following the Participant’s termination. If, on the date of termination, the Participant is not vested as to his or her entire SAR, the Shares covered by the unvested portion of the SAR shall revert to the Plan. If, after termination, the Participant does not exercise his or her SAR within the time specified herein, the SAR shall terminate, and the Shares covered by such SAR shall revert to the Plan.

(i) Death of Participant. If a Participant dies while a Service Provider, the SAR may be exercised following the Participant’s death within such period of time as is specified in the SAR Award Agreement (but in no event may the SAR be exercised later than the expiration of the term of such SAR as set forth in the SAR Award Agreement), by the personal representative of the Participant’s estate or by the person(s) to whom the SAR is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution. In the absence of a specified time in the SAR Award Agreement, the SAR shall remain exercisable for 12 months following the Participant’s death. If the SAR is not so exercised within the time specified herein, the SAR shall terminate, and the Shares covered by such SAR shall revert to the Plan.

B-8

11. Restricted Stock.

(a) Grant of Restricted Stock. Subject to the terms and conditions of the Plan, Restricted Stock may be granted to Participants at any time as shall be determined by the Administrator, in its sole discretion. Subject to Section 7(b) hereof, the Administrator shall have complete discretion to determine (i) the number of Shares subject to a Restricted Stock award granted to any Participant, and (ii) the conditions that must be satisfied, which typically will be based principally or solely on continued provision of services but may include a performance-based component, upon which is conditioned the grant, vesting or issuance of Restricted Stock. Restricted Stock may be granted in the form of restricted stock units that are not issued until the vesting conditions are satisfied. Until the Shares are issued, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the units to acquire Shares. Notwithstanding any provision of the Plan or any Award Agreement to the contrary, Awards of restricted stock units will be settled no later than two and one-half months after the end of the calendar year in which such Award vests.

(b) Other Terms. The Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms and conditions of Restricted Stock granted under the Plan. Restricted Stock grants shall be subject to the terms, conditions, and restrictions determined by the Administrator at the time the stock or the restricted stock unit is awarded. The Administrator may require the recipient to sign a Restricted Stock Award agreement as a condition of the Award. Any certificates representing the Shares of Restricted Stock awarded shall bear such legends as shall be determined by the Administrator.

(c) Restricted Stock Award Agreement. Each Restricted Stock grant shall be evidenced by an agreement that shall specify the purchase price (if any) and such other terms and conditions as the Administrator, in its sole discretion, shall determine; provided, however, if the Restricted Stock grant has a purchase price, such purchase price must be paid no more than 10 years following the date of grant.

12. Performance Shares.

(a) Grant of Performance Shares. Subject to the terms and conditions of the Plan, Performance Shares may be granted to Participants at any time as shall be determined by the Administrator, in its sole discretion. Subject to Section 7(b) hereof, the Administrator shall have complete discretion to determine (i) the number of Shares subject to a Performance Share Award granted to any Participant, and (ii) the conditions that must be satisfied, which typically will be based principally or solely on achievement of performance milestones but may include a service-based component, upon which is conditioned the grant or vesting of Performance Shares. Performance Shares shall be granted in the form of units to acquire Shares. Each such unit shall be the equivalent of one Share for purposes of determining the number of Shares subject to an Award. Until the Shares are issued, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the units to acquire Shares. Notwithstanding any provision of the Plan or any Award Agreement to the contrary, Awards of performance share units will be settled no later than two and one-half months after the end of the calendar year in which such Award vests.

(b) Other Terms. The Administrator, subject to the provisions of the Plan, shall have complete discretion to determine the terms and conditions of Performance Shares granted under the Plan.

Any certificates representing the Shares awarded shall bear such legends as shall be determined by the Administrator.

(c) Performance Share Award Agreement. Each Performance Share grant shall be evidenced by an agreement that shall specify such other terms and conditions as the Administrator, in its sole discretion, shall determine.

13. Performance Units.

(a) Grant of Performance Units. Performance Units are similar to Performance Shares, except that they shall be settled in cash in an amount equivalent to the Fair Market Value of the underlying Shares,

B-9

determined as of the vesting date. Subject to the terms and conditions of the Plan, Performance Units may be granted to Participants at any time and from time to time as shall be determined by the Administrator, in its sole discretion. The Administrator shall have complete discretion to determine the conditions that must be satisfied, which typically will be based principally or solely on achievement of performance milestones but may include a service-based component, upon which is conditioned the grant or vesting of Performance Units. Performance Units shall be granted in the form of units to acquire Shares. Each such unit shall be the cash equivalent of one Share. No right to vote or receive dividends or any other rights as a stockholder shall exist with respect to Performance Units or the cash payable thereunder. Notwithstanding any provision of the Plan or any Award Agreement to the contrary, Awards of performance share units will be settled no later than two and one-half months after the end of the calendar year in which such Award vests.

(b) Number of Performance Units. Subject to Section 7(b) hereof, the Administrator will have complete discretion in determining the number of Performance Units granted to any Participant.

15. Non-Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the recipient, only by the recipient. If the Administrator makes an Award transferable, such Award shall contain such additional terms and conditions as the Administrator deems appropriate; provided, however, no Option shall in any event be transferable for value.

16. Adjustments Upon Changes in Capitalization.

(a) Adjustments. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each outstanding Award, the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan upon cancellation, forfeiture or expiration of an Award, as well as the price per share of Common Stock covered by each such outstanding Award, the limit on the number of Shares that may be issued in conjunction with Restricted Stock, Performance Shares and Performance Units under Section 3, and the 162(m) Fiscal Year share issuance limits under Sections 7(a) and (b) hereof shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as

B-10

expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Award.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for a Participant to have the right to exercise his or her Option or SAR until 10 calendar days prior to such transaction as to all of the Awarded Stock covered thereby, including Shares as to which the Award would not otherwise be exercisable. In addition, the Administrator may provide that any Company repurchase option or forfeiture rights applicable to any Award shall lapse 100%, and that any Award vesting shall accelerate 100%, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised (with respect to Options and SARs) or vested (with respect to other Awards), an Award will terminate immediately prior to the consummation of such proposed action.

(c) Mergers, Reorganizations, Etc. In the event of a merger, consolidation, plan of exchange, acquisition of property or stock, separation, reorganization or liquidation to which the Company or a Subsidiary is a party or a sale of all or substantially all of the Company’s assets (each, a “Transaction”), the Board shall, in its sole discretion and to the extent possible under the structure of the Transaction, select one of the following alternatives for treating outstanding Awards under the Plan:

(i) Outstanding Awards shall remain in effect in accordance with their terms.

(ii) Each outstanding Award shall be assumed or an equivalent Award shall be substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. With respect to Awards granted to an Outside Director that are assumed or substituted for, if immediately prior to or after the Transaction the Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant, then the Participant shall fully vest in such Award and, with respect to Options and SARs, shall have the right to exercise such Options and SARs as to all of the Awarded Stock, including Shares as to which it would not otherwise be vested or exercisable. The amount, type of securities subject thereto and, if applicable, exercise price of the assumed or substituted Awards shall be determined by the Board, taking into account the relative values of the companies involved in the Transaction and the exchange ratio, if any, used in determining shares of the successor corporation, or Parent or Subsidiary thereof, to be issued to holders of Shares. Unless otherwise determined by the Board and except as otherwise provided above with respect to Outside Directors, the assumed or substituted Awards shall be vested only to the extent that the vesting requirements relating to Awards granted hereunder have been satisfied.

(iii) The Board shall provide a 30 calendar-day period prior to the consummation of the Transaction during which outstanding Options and SARs may be exercised to the extent then exercisable, and upon the expiration of such 30 calendar-day period, all unexercised Options and SARs shall immediately terminate. The Board may, in its sole discretion, accelerate the exercisability of Options and SARs so that they are exercisable in full during such 30 calendar-day period. The Board may also, in its sole discretion, accelerate the vesting of Restricted Stock, Performance Share or Performance Unit Awards.

17. Date of Grant. The date of grant of an Award shall be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator; provided, however, the date of grant of an Option shall be the date when the Option is granted and its exercise price is set, consistent with Applicable Laws and applicable financial accounting rules. Notice of the determination shall be provided to each Participant within a reasonable time after the date of such grant.

18. Amendment and Termination of the Plan.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. With respect to any Participant or Service Provider who is resident outside of the United States, the

B-11

Administrator may, in its sole discretion, amend or vary the terms of the Plan in order to conform such terms with the requirements of local law, to meet the goals and objectives of the Plan, and may, in its sole discretion, establish administrative rules, regulations and procedures to facilitate the operation of the Plan in such non-U.S. jurisdictions. The Administrator may, where it deems appropriate in its sole discretion, establish one or more sub-plans of the Plan for these purposes.

(b) Stockholder Approval. The Company shall obtain stockholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws. Such stockholder approval, if required, shall be obtained in such a manner and to such a degree as is required by the applicable law, rule or regulation.

(c) Effect of Amendment or Termination. Except as otherwise provided in Section 23, no amendment, alteration, suspension or termination of the Plan shall impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing (or electronic format) and signed by the Participant and the Company.

19. Conditions Upon Issuance of Shares.

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Award unless the exercise of the Award or the issuance and delivery of such Shares (or with respect to Performance Units, the cash equivalent thereof) shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations. As a condition to the exercise or receipt of an Award, the Company may require the person exercising or receiving such Award to represent and warrant at the time of any such exercise or receipt that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

20. Liability of Company.

(a) Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

(b) Grants Exceeding Allocated Shares. If the Awarded Stock covered by an Award exceeds, as of the date of grant, the number of Shares which may be issued under the Plan without additional stockholder approval, such Award shall be void with respect to such excess Awarded Stock, unless stockholder approval of an amendment sufficiently increasing the number of Shares subject to the Plan is timely obtained in accordance with Section 18(b) of the Plan.

21. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

22. Governing Law. The Plan and all Award Agreements entered into under the Plan shall be construed in accordance with and governed by the laws of the State of Oregon, without regard to its conflicts of laws provisions.

23. Compliance with Code Section 409A. Awards granted under the Plan are intended to be exempt from Code Section 409A. Notwithstanding any other provision of the Plan or any Award Agreement to the contrary, to the extent that the Administrator determines that any Award granted under the Plan is subject to Section 409A of the Code, it is the intent of the parties to the applicable Award Agreement that the Plan incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code and that such Award Agreement and the terms of the Plan as applicable to such Award be interpreted and construed in compliance

B-12

with Section 409A of the Code and the Treasury regulations and other interpretive guidance issued thereunder. Notwithstanding the foregoing, the Company shall not be required to assume any increased economic burden in connection therewith. Although the Company and the Administrator intend to administer the Plan so that it will comply with the requirements of Code Section 409A, neither the Company nor the Administrator represents or warrants that the Plan will comply with Code Section 409A or any other provision of federal, state, local, or non-United States law. Neither the Company, its subsidiaries, nor their respective directors, officers, employees or advisers shall be liable to any Participant (or any other individual claiming a benefit through any Participant) for any tax, interest, or penalties the Participant may owe as a result of compensation paid under the Plan, and the Company and its subsidiaries shall have no obligation to indemnify or otherwise protect the Participant from the obligation to pay any taxes pursuant to Code Section 409A.

24. Prohibition on Acceleration of Payments. The time or schedule of any settlement or amount scheduled to be paid pursuant to the terms of the Plan or any Award Agreement that is a “deferral of compensation” under Code Section 409A may not be accelerated except as otherwise permitted under Code Section 409A and the guidance and Treasury regulations issued thereunder.

25. Time and Form of Settlement. The time and form of settlement of the Participant’s Award shall be made in accordance with the provisions of the Plan and the applicable Award Agreement, provided that if a Participant receives settlement of an Award upon termination of employment for reasons other than death, the payment at such time can be characterized as a “short-term deferral” for purposes of Code Section 409A or as otherwise exempt from the provisions of Code Section 409A, or if any portion of the payment cannot be so characterized, and the Participant is a “specified employee” under Code Section 409A, such portion of the payment shall be delayed until the earlier to occur of the Participant’s death or the date that is six months and one day following the Participant’s termination of employment (the “Delay Period”). Upon the expiration of the Delay Period, all payments delayed pursuant to this Section 25 shall be paid to the Participant in a lump sum and remaining payments, if any, shall be paid in accordance with the terms of the applicable Award Agreement. For purposes of the Plan and any Award Agreement, the terms “terminate,” “termination,” “termination of employment,” and variations thereof, as used in this Plan and any Award Agreement, are intended to mean a termination of employment that constitutes a “separation from service” under Code Section 409A.

(b) Any rule or decision by the Committee that is not inconsistent with the provisions of the Plan shall be conclusive and binding on all persons including, without limitation, the Company, the Participants, other eligible employees, and their respective successors in interest, and shall be given the maximum deference permitted by law.

5. Eligibility.

[(a) Participation.] The employees eligible to participate in the Plan for a given Performance Period shall be determined by the Committee and are generally expected to include executive officers of the Company who are subject to Section 16 of the Securities Exchange Act of 1934, as amended, and any other key employees who are specifically designated by the Committee for participation in the Plan in its sole discretion.

No person shall be automatically entitled to participate in the Plan.

6. Performance Goal Determination. On the Target Determination Date, the Committee, in its sole discretion, shall establish the Performance Goals for each Participant for the Performance Period. Such Performance Goals shall be set forth in writing on or prior to the Target Determination Cutoff Date with respect to Awards intended to qualify as Performance-Based Compensation.

7. Target Award Determination. On the Target Determination Date, the Committee, in its sole discretion, shall establish a Target Award for each Participant and may establish multiples or percentages thereof. Each Participant’s Target Award shall represent the amount of cash or the number of Shares that can be earned by the Participant under the Plan during the Performance Period, based upon the Performance Goals achieved and the level of achievement for such period as determined by the Committee in its discretion. Each Participant’s Target Award shall be set forth in writing on or prior to the Target Determination Cutoff Date with respect to Awards intended to qualify as Performance-Based Compensation.

8. Payout Formula Determination. On the Target Determination Date, the Committee, in its sole discretion, shall establish a Payout Formula for purposes of determining the Award (if any) payable to each Participant. Each Payout Formula shall be set forth in writing on or prior to the Target Determination Cutoff Date with respect to Awards intended to qualify as Performance-Based Compensation and shall provide for the payment of all or a portion of a Participant’s Award upon the Committee’s certification of achievement of a Performance Goal in accordance with Section 9(a).

9. Payout Determination; Award Payment.

(a) Payout Determination and Certification. On each Payout Determination Date, the Committee shall certify in writing (which may be by approval of the minutes in which the certification was made) the extent to which the Performance Goals applicable to each Participant for the Performance Period were achieved or

C-5

exceeded. The Award for each Participant shall be determined by applying the Payout Formula to the level of actual performance that has been certified by the Committee. Notwithstanding any contrary provision of the Plan, the Committee, in its sole discretion, may eliminate or reduce the Award payable to any Participant below that which otherwise would be payable under the Payout Formula.

(b) Right to Receive Payment. Each Award under the Plan shall be paid solely from the general assets of the Company. Nothing in this Plan shall be construed to create a trust or to establish or evidence any Participant’s claim of any right to payment of an Award other than as an unsecured general creditor with respect to any payment to which he or she may be entitled.

(c) Form of Distributions. The Company shall distribute all Awards to the Participant in Shares or cash in its discretion.

(d) Timing of Distributions. Subject to Section 9(f) below, the Company shall distribute amounts payable to Participants as soon as is practicable following the determination and written certification of the Award for a Performance Period, and in any event no later than the date that is two and one-half months following the last day of the Fiscal Year coinciding with or next following the last day of the quarter for which achievement of a Performance Goal is certified by the Committee in accordance with Section 9(a).

(e) Death of Participant. If a Participant dies prior to the date such Participant’s Award would be distributed pursuant to this Section 9 or Section 10, such Award shall be paid to the personal representative of the Participant’s estate or the person(s) to whom the Award is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution.

(f) Deferral. The Committee may defer payment of Awards, or any portion thereof, to Participants as the Committee, in its discretion, determines to be necessary to preserve the deductibility of such amounts under Section 162(m), provided that payment of the Award is made as soon as reasonably practicable following the first date on which the Committee anticipates or reasonably should anticipate that, if the payment were made on such date, the Company’s deduction with respect to such payment would no longer be restricted due to the application of Section 162(m). In addition, the Committee, in its sole discretion, may permit a Participant to defer receipt of the payment of Shares or cash that would otherwise be delivered to a Participant under the Plan. Any such deferral elections shall be subject to such rules and procedures as shall be determined by the Committee in its sole discretion and shall be made in accordance with Section 409A of the Code.

10. Termination of Employment; Change of Control.

(a) General. Except as otherwise expressly provided in this Section 10, upon a Participant’s termination of employment prior to the last day of the quarter for which achievement of a Performance Goal is certified by the Committee in accordance with Section 9(a), a Participant shall forfeit the right to receive any Awards under this Plan with respect to such quarter or with respect to any future quarters in the Performance Period. Upon a Participant’s termination of employment for Cause following the last day of the quarter for which achievement of the Performance Goal is certified by the Committee in accordance with Section 9(a) but prior to the date on which the Participant’s Award with respect to such Performance Goal is distributed pursuant to Section 9(d) above, such Participant shall forfeit the right to receive such Award.

(b) Death or Disability. Subject to the express provisions of the Participant’s Award, if a Participant’s employment is terminated as a result of the Participant’s death or Disability prior to the last day of a quarter and achievement of a Performance Goal as of the last day of such quarter is certified by the Committee in accordance with Section 9(a), such Participant shall be entitled to receive a pro-rata Award with respect to such Performance Goal, as determined in accordance with Section 9(a) and payable in accordance with Section 9(d).

(c) Termination without Cause. Subject to the express provisions of the Participant’s Award, if a Participant’s employment is terminated by the Company without Cause prior to the last day of a quarter and achievement of a Performance Goal as of the last day of such quarter is certified by the Committee in

C-6

accordance with Section 9(a), such Participant shall be entitled to receive a pro-rata Award with respect to such Performance Goal, as determined in accordance with Section 9(a) and payable in accordance with Section 9(d).

(d) If the Participant has in effect an employment, retention, change of control, severance or similar agreement with the Company or any affiliate thereof that provides for the effect of a Change of Control on all or any portion of the Participant’s Awards, then such agreement shall control with respect to such Awards in the event of a Change of Control. In all other cases, unless the Committee shall otherwise expressly provide in the agreement relating to an Award under the Plan, in the event of a Potential Change of Control, the Committee shall determine whether a Performance Goal has been achieved as of the last day of the prior quarter, and if such achievement equals or exceeds 50% of the Performance Goal corresponding to the threshold award level, then, in the event of a Change of Control, the Participant shall be entitled to receive a portion of his Award as follows: if a Participant has received all or any portion of his Award for a Performance Period prior to a Change of Control, no further Awards shall be payable to such Participant under this Plan following such Change of Control, and if a Participant has not received any portion of his Award for a Performance Period prior to a Change of Control, the Company shall distribute, within sixty days following such Change of Control, a pro-rata Award to such Participant based on his Target Award, provided the Participant is actively employed by the Company immediately prior to such Change of Control, and no further Awards shall be payable to such Participant under this Plan. Unless the Committee shall otherwise expressly provide in the agreement relating to an Award under the Plan, such pro-rata Award shall equal the Target Award multiplied by the ratio of: (x) the number of full days elapsed from the beginning of the Performance Period to and including the date of the Change of Control to (y) the number of full days in the Performance Period. In the event of a Potential Change of Control and if the achievement determined by the Committee above is less than 50% of the Performance Goal corresponding to the threshold award level, then, in the event of a Change of Control, the Committee may in its discretion provide for payment of a portion of such Award in such amounts as the Committee may determine in its sole discretion, provided any Participant receiving such Award is actively employed by the Company immediately prior to such Change of Control. For purposes of this Section 10(d), a “Potential Change of Control” shall exist during any period in which the following items exist: (i) the Company enters into an agreement, the consummation of which would result in the occurrence of a Change of Control; (ii) any person (including the Company) publicly announces an intention to take or to consider taking actions which if consummated would constitute a Change of Control; or (iii) the Board adopts a resolution to the effect that, for purposes of the Plan, a potential change of control exists.

11. Term of Plan. The Plan shall be effective as of the Effective Date[, with the last Performance Period under the Plan to begin January 1, 2011]. The Plan shall terminate with respect to all Performance Periods unless it is approved at the 2008 annual meeting of the stockholders of RadiSys Corporation. Once approved by the stockholders of RadiSys Corporation, the Plan shall continue until terminated under Section 12 of the Plan.

12. Amendment and Termination of the Plan. The Committee may amend, modify, suspend or terminate the Plan, in whole or in part, at any time, including adopting amendments deemed necessary or desirable to correct any defect or to supply omitted data or to reconcile any inconsistency in the Plan or in any Award granted hereunder; provided, however, no amendment, modification, suspension or termination shall be made which would (i) impair any payments to Participants made prior to such amendment, modification, suspension or termination, unless the Committee has made a determination that such amendment or modification is in the best interests of all persons to whom Awards have theretofore been granted; provided further, however, in no event may such an amendment or modification result in an increase in the amount of compensation payable pursuant to such Award or (ii) cause compensation that is, or may become, payable hereunder to fail to qualify as Performance-Based Compensation. To the extent necessary or advisable under applicable law, including Section 162(m), Plan amendments shall be subject to stockholder approval. At no time before the actual distribution of funds or stock to Participants under the Plan shall any Participant accrue any vested interest or right whatsoever under the Plan except as otherwise stated in this Plan.

C-7

13. Adjustments Upon Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each outstanding Award, the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan upon cancellation or forfeiture of an Award, as well as the per Participant limit on the number of Shares that may be covered under grants of Awards that are intended to be Performance-Based Compensation in any one Fiscal Year under Section 3 hereof, shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Committee, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Common Stock subject to an Award.

14. Withholding. Distributions pursuant to this Plan shall be subject to all applicable U.S. federal, state, and local tax and withholding requirements and the applicable withholding tax requirements of any other country or jurisdiction. The Committee, in its sole discretion, may allow Participants to satisfy all or part of their withholding tax obligations by electing to have the Company withhold from the Shares to be issued pursuant to Section 9 or 10 that number of Shares having a fair market value equal to the minimum amount required to be withheld (but no more). The fair market value of any Shares to be withheld shall be determined in the sole discretion of the Committee on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares withheld for this purpose shall be made in such form and under such conditions as the Committee may deem necessary or advisable. The Company shall also have the right to deduct from all cash payments made to a Participant (whether or not such payment is made in connection with this Plan) any applicable taxes required to be withheld with respect to such payments.

15. No Employment Rights. No statement in this Plan should be construed to grant any employee an employment contract of fixed duration or any other contractual rights, nor should this Plan be interpreted as creating an implied or an express contract of employment or any other contractual rights between the Company and its employees. Except as otherwise expressly agreed to in writing by the Company and an employee of the Company, the employment relationship between the Company and its employees is terminable at-will. This means that an employee of the Company may terminate the employment relationship at any time and for any reason or no reason.

16. Successors. All obligations of the Company under the Plan, with respect to Awards granted hereunder, shall be binding on any successor to RadiSys Corporation, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business or assets of RadiSys Corporation.

17. Indemnification. Each person who is or shall have been a member of the Committee, or of the Board, shall be indemnified and held harmless by the Company against and from (a) any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan or any Award, and (b) from any and all amounts paid by him or her in settlement thereof, with the approval of RadiSys Corporation, or paid by him or her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Articles of Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under any power that the Company may have to indemnify them or hold them harmless.

18. Nonassignment. The rights of a Participant under this Plan shall not be assignable or transferable by the Participant except by will or the laws of intestacy.

19. Governing Law. The Plan shall be governed by the laws of the State of Oregon, without regard to its conflicts of laws provisions.

20. Conditions Upon Issuance of Shares.

(a) Legal Compliance. Shares shall not be issued pursuant to an Award unless the issuance and delivery of such Shares shall comply with applicable laws and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations. As a condition to the receipt of an Award, the Company may require the person receiving such Award to represent and warrant at the time of any such receipt that the Shares are being held only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

21. Liability of Company.

(a) Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

(b) Grants Exceeding Allocated Shares. If the number of Shares covered by an Award exceeds, as of the date of grant, the number of Shares which may be issued under the Plan without additional stockholder approval, such Award shall be void with respect to such excess Shares, unless stockholder approval of an amendment sufficiently increasing the number of Shares subject to the Plan is timely obtained in accordance with Section 12 of the Plan.

22. Compliance with Code Section 409A. The Plan and the Awards granted hereunder are intended to meet the “short-term deferral” exception to the provisions of Section 409A of the Code and Treasury regulations issued thereunder or to otherwise comply with Section 409A of the Code and the Treasury regulations and guidance issued thereunder. Notwithstanding any provision of the Plan to the contrary, the Plan shall be interpreted and construed consistent with this intent. Notwithstanding the foregoing, the Company shall not be required to assume any increased economic burden in connection therewith.
