PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus. This summary is not complete and does not contain all of the information that you should consider before deciding to invest in our securities. We urge you to read this entire prospectus carefully, including the “Risk Factors” section and the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2006, filed with the Securities and Exchange Commission (“SEC”) on March 2, 2007 and our Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2007, and June 30, 2007 filed with the SEC on May 8, 2007, and August 7, 2007, respectively. As used in this prospectus, unless context otherwise requires, the words “we,” “us,” “our,” “the Company” and “RadiSys” refer to RadiSys Corporation and include all of our consolidated subsidiaries.

THE COMPANY

RadiSys Corporation is a leading provider of embedded advanced solutions for the communications networking and commercial systems markets. Through innovative product planning, intimate customer collaboration, and combining innovative technologies and industry leading architecture, we help original equipment manufacturers (“OEMs”), systems integrators and solution providers bring better products to market faster and more economically. Our products include embedded boards, application enabling platforms and turn-key systems, which are used in today’s complex computing, processing and network intensive applications.

Strategy

Our strategy is to provide customers with standards-based advanced embedded solutions in our target markets. We believe this strategy enables our customers to focus their resources and development efforts on their key areas of competency allowing them to provide higher value systems with a time-to-market advantage and a lower total cost of ownership. Historically, system makers had been largely vertically integrated, developing most, if not all, of the functional building blocks of their systems. System makers are now more focused on their core expertise, such as specific application software, and are looking for partners like RadiSys to provide them with standards-based, merchant-supplied building blocks for a growing number of processing and networking functions.

End Markets

We provide application enabling solutions to the following two distinct markets:

Communications Networking — The communications networking market consists primarily of networking infrastructure and applications for deployment within our wireless and IP networking and messaging markets.

Commercial Systems — The commercial systems market includes the following sub-markets: medical systems, test and measurement equipment, transaction terminals and industrial automation equipment.

Market Drivers

We believe there are a number of fundamental drivers for growth in the embedded solutions market, including:

• Increasing desire by OEMs to utilize standards-based, merchant-supplied modular building blocks and platforms to develop their new systems. We believe OEMs are combining their internal development efforts with merchant-supplied building blocks and platforms from partners like RadiSys to deliver a larger number of more valuable new products to market faster at a lower total cost of ownership.

• Increasing usage levels of widely adopted technologies such as Ethernet, IP, Linux, media processing and CPU, GPU and NPU processors to provide programmable, intelligent and networked functionality to a wide variety of applications, including wireless, wireline and data communications, network security, image processing, transaction and monitoring and control.

1

• Increasing demand for standards-based solutions, such as Advanced Telecommunications Architecture (ATCA), Session Initiation Protocol, IP Multimedia Subsystem and Computer-on-Module Express that motivates system makers to take advantage of proven and validated standards-based products.

Our principal offices are located at 5445 N.E. Dawson Creek Drive, Hillsboro, OR 97124. Our telephone number is (503) 615-1100. Our website address is www.radisys.com. Information contained on, or that is accessible through, our website should not be considered to be part of this prospectus.

RECENT DEVELOPMENTS

Acquisition of ATCA and compact PCI Product Lines from Intel Corporation.

On September 12, 2007, we completed an acquisition of certain assets of the Modular Communications Platform Division (“MCPD”), including products in the Advanced Telecommunications Architecture (ATCA) and compact PCI lines, of Intel Corporation, a Delaware corporation (“Intel”). In connection with the completion of the acquisition, we paid Intel approximately $31.8 million in cash. The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the amended and restated purchase agreement to be filed.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges for each of the periods indicated:

	Six Months Ended June 30,			Year Ended December 31,
	2007	2006		2006	2005		2004		2003		2002
Ratio of earnings to fixed charges (1) (2)	—	8.3	x	—	7.9	x	5.1	x	2.1	x	—

(1) Ratio of earnings to fixed charges is calculated by dividing earnings, as defined, by fixed charges, as defined. For this purpose, “earnings” means net loss from operation plus minority interests in consolidated subsidiaries or income (loss) from equity investees, fixed charges and amortized capital interest less interest capitalized and our minority interest in pretax income (loss) of subsidiaries that have not incurred fixed charges. For this purpose, “fixed charges” means interest expensed and capitalized, amortized premiums, discounts and capitalized expenses related to indebtedness and estimated interest within rental expense.

(2) For the six months ended June 30, 2007 and for the years ended December 31, 2006 and 2002, our earnings were insufficient to cover fixed charges; the amount of additional earnings needed to cover fixed charges for each period was $15.4 million, $13.8 million and $4.5 million, respectively.

RISK FACTORS

The following summarizes the material risks of purchasing or owning shares of our common stock. Additional unknown risks may also impair our financial performance and business operations. Our business, financial condition and/or results of operation may be materially adversely affected by the nature and impact of these risks. In such case, the market value of our securities could be detrimentally affected, and investors may lose part or all of the value of their investment. You should carefully consider the risks and uncertainties described below before purchasing our common stock.

Risks Related To Our Business

Our business is inherently risky and we face numerous and varied risks, both known and unknown. Despite the knowledge and experience of management, careful evaluation, and strategic planning, we may not be able to overcome the risks associated with our business, which may prevent us from achieving our goals.

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

During 2006, we derived 66.7% of our revenues from five customers. These five customers were Nokia, Nortel, Comverse, Philips Medical Systems and Avaya. During 2006, revenues attributable to Nokia and Nortel were 39.4% and 10.3%, respectively. A financial hardship experienced by, or a substantial decrease in sales to any one of our top customers could materially affect revenues and profitability. Generally, these customers are not the end-users of our products. If any of these customers’ efforts to market the end products we design and manufacture for them or the end products into which our products are incorporated are unsuccessful in the marketplace our design wins, sales and/or profitability will be significantly reduced. Furthermore, if these customers experience adverse economic conditions in the markets into which they sell our products (end markets), we would expect a significant reduction in spending by these customers. Some of the end markets that these customers sell our products into are characterized by intense competition, rapid technological change and economic uncertainty. Our exposure to economic cyclicality and any related fluctuation in demand from these customers could have a material adverse effect on our revenues and financial condition.

We are shifting our business from predominately perfect fit (custom) solutions to more standards-based products, such as ATCA, COM Express and Media Servers. This requires substantial expenditures for R&D that could adversely affect our short-term earnings and, if this strategy is not successful could have a material adverse effect on our long-term revenues, profitability and financial condition.

We are shifting our business from predominately perfect fit solutions to more standards-based solutions, such as ATCA, COM Express and Media Server products. There can be no assurance that this strategy will be successful. This strategy requires us to make substantial expenditures for R&D in new technologies that we reflect as a current expense in our financial statements. We believe that these investments in standards-based products and new technologies will allow us to provide a broader set of products and building blocks to take to market and position us to grow on a long-term basis. Most of these investments are not expected to result in significant revenues for at least twelve to twenty-four months. Accordingly, these expenditures could adversely affect our short-term earnings. In addition, there is no assurance that these new products and technologies will be accepted by our customers and, if accepted, how large the market will be for these products or what the timing will be for any meaningful revenues. If we are unable to successfully develop and sell standards-based products to our customers, our revenues, profitability and financial condition could be materially adversely affected. Additionally, if we successfully develop standards-based products we may incur incremental R&D expenses as we tailor the standards-based products for our customers. Furthermore, we are building standards-based products to meet industry standards that define the basis of compatibility in operation and communication of a system supported by different vendors. Those standards constantly change and new competing standards emerge. The development or adaptation of products and technologies require us to commit financial resources, personnel and time significantly in advance of sales. In order to compete, our decisions with respect to those commitments must accurately anticipate, sometimes two years or more in advance, both future demand and the technologies that will win market acceptance to meet that demand.

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

Most of our major customers have contracts but these contracts do not commit them to purchase a minimum amount of our products. These contracts generally require our customers to provide us with forecasts of their anticipated purchases. However, our experience indicates that customers can change their purchasing patterns quickly in response to market demands and therefore these forecasts may not be relied upon to accurately forecast sales. From time to time we provide projections to our shareholders and the investment community of our future sales and earnings. Since we do not have long-term purchase commitments from our major

4

customers and the customer order cycle is short, it is difficult for us to accurately predict the amount of our sales and related earnings in any given period. Our projections are based on management’s best estimate of sales using historical sales data, information from customers and other information deemed relevant. These projections are highly subjective since sales to our customers can fluctuate substantially based on the demands of their customers and the relevant markets. Our period to period revenues have varied in the past and may continue to vary in the future. In addition and as stated above, we have a high degree of customer concentration. Any significant change in purchases by any one of our largest customers can significantly affect our sales and profitability.

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

• changes in customer product needs;

• changes in the level of customers’ inventory;

• changes in business and economic conditions, including a downturn in the semiconductor industry; and

• market acceptance of our products.

We have recently experienced significant changes in purchases by one of our large customers which adversely impacted the fiscal period in which it occurred. If our actual sales or earnings are less than the projected amounts, the price of our common stock may be adversely affected and accordingly our shareholders should not place undue reliance on these projections.

In addition, the price of our common stock may be adversely affected due to other factors, such as changes in analysts’ estimates regarding earnings, or may be due to factors relating to the commercial systems and communication networking markets in general. Shareholders should be willing to incur the risk of such fluctuations.

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

From time to time we estimate the revenue from design wins, which represents three years of revenue once product development has ramped into production. If a design win actually ramps into production, the average ramp into production begins about 12 to 18 months after the initial design win, although some more complex projects can take up to 24 months or longer. After that, there is an additional time lag from the start of production ramp to peak revenue. Not all design wins ramp into production and even if a design win ramped into production, the volumes derived from such projects may be less than we had originally estimated. Design wins are sometimes canceled or delayed, or can perform below original expectations, which can adversely impact anticipated revenues and profitability.

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

We derive our revenues from a number of diverse end markets, some of which are subject to significant cyclical changes in demand. In 2006, we derived 74.4% and 25.6% of our revenues from the communications networking and commercial systems markets, respectively. We believe that our revenues will continue to be derived primarily from these two markets. Communications networking revenues include, but are not limited to, sales to Airvana, Aspect Medical Systems, Avaya, Comverse, Hewlett Packard, Huawei Technologies Co., IBM, Intel Corporation, Intercall, a division of West Corporation, Lucent, NexTone Communications, Nokia, Nortel and Siemens AG. Commercial systems revenues include, but are not limited to, sales to Agilent Technologies, Arrow Electronics, Fluke Electronics, Philips Medical Systems, Tektronix and Universal Instruments. Generally, our customers are not the end-users of our products. If our customers experience adverse economic conditions in the markets into which they sell our products (end markets), we would expect a significant reduction in spending by our customers. Some of these end markets are characterized by intense competition, rapid technological change and economic uncertainty. Our exposure to economic cyclicality and any related fluctuation in customer demand in these end markets could have a material adverse effect on our revenues and financial condition. Significant reduction in our customers’ spending, such as what we experienced in 2001 and 2002, will result in decreased revenues and earnings. We continue to execute on our strategy of expanding into new end markets either through new product development projects with our existing customers or through new customer relationships, but no assurance can be given that this strategy will be successful.

5

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

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

We depend on a few suppliers, or in some cases one supplier, for a continuing supply of the components we use in the manufacture of our products and any disruption in supply could adversely impact our financial performance. For example, we currently solely rely on Intel for the supply of some microprocessors and other components. Alternative sources of components that are procured from one supplier or a limited number of suppliers would be difficult to locate and/or it would require a significant amount of time and resources to establish.

We also rely on contract manufacturers for the supply of approximately 80% of all of our unit volume. If these third party manufacturers fail to adequately perform our revenues and profitability could be adversely affected. Among other things, inadequate performance from our contract manufacturers could include the production of products that do not meet our high quality standards or schedule and delivery requirements and could cause us to invest in additional internal resources as we lose productivity on other important projects. In addition, alternative internal or external sources of manufacturing for RadiSys products could require significant time and resources to establish or transition. We have experienced less than optimal service from one of our contract manufacturers in North America. As a result, we have discontinued our relationship with this contract manufacturer and are currently transitioning the majority of this production to our Hillsboro facility. However, we may incur additional and unanticipated expenses or delays which may have a material adverse effect on our business or our financial performance. Also, due to the inherent risks associated with the transfer of production we may incur additional expenses related to adverse purchase commitments or excess and obsolete inventory.

The failure to successfully integrate Convedia’s business and ATCA and compact PCI product lines acquired from Intel into our operations in the expected time frame, or at all, may adversely affect our future results.

We believe that the acquisition of Convedia, completed in September 2006 and the acquisition of ATCA and compact PCI product lines from Intel in September 2007 will result in certain benefits, including expanded global reach and increased product offerings. However, to realize these anticipated benefits, Convedia’s business and the ATCA and compact PCI product lines must be successfully integrated into RadiSys’ operations by focusing on general and administrative, manufacturing and marketing and sales cooperation. The success of these acquisitions will depend on our ability to realize these anticipated benefits from integrating Convedia’s business and the acquired product lines into our operations. We may fail to realize the anticipated benefits of these acquisitions on a timely basis, or at all, for a variety of reasons, including the following:

• failure to effectively coordinate sales and marketing efforts to communicate the capabilities of the Company;

• potential difficulties integrating and harmonizing financial reporting or other critical systems; and

• the loss of key employees.

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

We operate in intensely competitive industries that experience rapid technological developments, changes in industry standards, changes in customer requirements, and frequent new product introductions and improvements. If we are unable to respond quickly and successfully to these developments, we may lose our competitive position, and our products or technologies may become uncompetitive or obsolete. To compete successfully, we must maintain a successful R&D effort, develop new products and production processes, and improve our existing products and processes at the same pace or ahead of our competitors. We may not be able to

6

successfully develop and market these new products; the products we invest in and develop may not be well received by customers; and products developed and new technologies offered by others may affect the demand for our products. These types of events could have a variety of negative effects on our competitive position and our profitability and financial condition, such as reducing our revenue, increasing our costs, lowering our gross margin percentage, and requiring us to recognize and record impairments of our assets.

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

We compete with a number of companies providing embedded systems, including Advantech Co., AudioCodes, Embedded Communications Computing, a division of Motorola, a division within Emerson, a division within General Electric Company, Hewlett Packard, a division within IBM, Interphase, IP Unity, Kontron AG, Mercury Computer Systems and Sun Microsystems. Because the embedded systems market is growing, it is attracting new non-traditional competitors. These non-traditional competitors include contract-manufacturers that provide design services and Asian-based original design manufacturers. Some of our competitors and potential competitors have a number of significant advantages over us, including:

• a longer operating history;

• greater name recognition and marketing power;

• preferred vendor status with our existing and potential customers; and

• significantly greater financial, technical, marketing and other resources, which allow them to respond more quickly to new or changing opportunities, technologies and customer requirements.

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

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

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

Future acquisitions and partnerships may involve the use of significant amounts of cash, potentially dilutive issuances of equity or equity-linked securities, issuance of debt and amortization of intangible assets with determinable lives. We may also be required to charge against earnings upon consummation of the acquisition the value of an acquired business’ technology that does not meet the accounting definition of “completed technology.” Moreover, to the extent that any proposed acquisition or strategic investment is not favorably received by shareholders, analysts and others in the investment community, the price of our common stock could be adversely affected. In addition, acquisitions or strategic investments involve numerous risks, including:

• difficulties in the assimilation of the operations, technologies, products and personnel of the acquired company;

• the diversion of management’s attention from other business concerns;

• risks of entering markets in which we have no or limited prior experience;

• the potential loss of key employees of the acquired company; and

• performance below expectations by an acquired business.

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

7

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

In 2006, as measured by delivery destination, we derived 4.0% of our revenues from Canada and Mexico, 48.1% of our revenues from EMEA and 17.3% from Asia Pacific. In 2004, we opened a development center in Shanghai, China and began to utilize a contract manufacturer in Shenzhen, China. For the year ended December 31, 2006, approximately 52% of our total revenues were associated with products produced at our China contract manufacturer. Also during 2006 we completed the acquisition of Convedia, which includes significant operations in Vancouver, British Columbia. As a result of all these activities, we are subject to worldwide economic and market condition risks generally associated with global trade, such as fluctuating exchange rates, tariff and trade policies, domestic and foreign tax policies, foreign governmental regulations, political unrest, wars and other acts of terrorism and changes in other economic conditions. These risks, among others, could adversely affect our results of operations or financial position. Additionally, some of our sales to overseas customers are made under export licenses that must be obtained from the United States Department of Commerce. Protectionist trade legislation in either the United States of America or other countries, such as a change in the current tariff structures, export compliance laws, trade restrictions resulting from war or terrorism, or other trade policies could adversely affect our ability to sell or to manufacture in international markets. Furthermore, revenues from outside the United States of America are subject to inherent risks, including the general economic and political conditions in each country. These risks, among others, could adversely affect our results of operations or financial position.

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

We cannot provide absolute assurance that we will generate sufficient taxable income to fully utilize the net deferred tax assets of $30.3 million as of December 31, 2006. We may not generate sufficient taxable income due to earning lower than forecasted net income or incurring charges associated with unusual events, such as restructurings and acquisitions. Accordingly, we may record a full valuation allowance against the deferred tax assets if our expectations of future taxable income are not achieved. On the other hand, if we generate taxable income in excess of our expectations, the valuation allowance may be reduced accordingly. We also cannot provide absolute assurance that future income will support the carrying amount of goodwill and intangibles of $110.1 million on the Consolidated Balance Sheet as of December 31, 2006, and therefore, we may incur an impairment charge in the future.

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

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

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

We are a technology dependent company, and our success depends on developing and protecting our intellectual property. We rely on patents, copyrights, trademarks and trade secret laws to protect our intellectual property. At the same time, our products are complex, and are often not patentable in their entirety. We also license intellectual property from third parties and rely on those parties to maintain and protect their technology. We cannot be certain that our actions will protect proprietary rights. If we are unable to adequately protect our technology, or if we are unable to continue to obtain or maintain licenses for protected technology from third parties, it could have a material adverse effect on our results of operations. In addition, some of our products are now designed, manufactured and sold outside of the United States of America. Despite our precautions to protect our intellectual property, this international exposure may reduce or limit protection of our intellectual property which is more prone to design piracy.

Changes in stock-based compensation accounting rules have adversely impacted our operating results and may adversely impact our stock price.

On December 16, 2004, the Financial Accounting Standards Board issued a Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), “Share-Based Payment” (“SFAS 123R”). SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized as expense in the financial statements based on their fair values and does not allow the pro forma disclosure previously used as an alternative to financial statement recognition.

8

We were required to adopt SFAS 123R in the first quarter of 2006. Under SFAS 123R, we applied the Black-Scholes valuation model in determining the fair value of share-based payments, with adjustments to the methodology as necessary for reporting under SFAS 123R guidelines. As a result, our operating results for the year ended December 31, 2006 contain, and our operating results for future periods will contain, a charge for share-based compensation related to stock options and shares pursuant to the 1996 Employee Stock Purchase Plan (“ESPP”), in addition to the share-based compensation associated with our restricted share awards and restricted stock units (“restricted stock”). SFAS 123R had a significant impact on our operating results for the year ended December 31, 2006, with SFAS 123R charges of $6.6 million increasing operating losses to $22.2 million, and we expect the adoption of SFAS 123R will continue to have a significant adverse impact on our operating results in the future. We anticipate that stock-based compensation will increase by $3.4 million to approximately $10 million in 2007 due primarily to the 2004 acceleration of employee stock options with an option price greater than $15.99. As a result of the acceleration, we reduced the amount of stock based compensation expense recognized in 2006; however, in 2007 stock based compensation expense will increase as the benefit from the acceleration will have been fully utilized. The increase is also due to the acquisition of Convedia. We cannot predict the effect that this adverse impact on our reported operating results will have on the trading price of our common stock.

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

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

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

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

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

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

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

9

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

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

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

• authorize our board of directors to issue up to 10,000,000 shares of preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without prior shareholder approval to increase the number of outstanding shares and deter or prevent a takeover attempt;

• establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by shareholders at shareholder meetings;

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

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

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

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

We may need to raise additional capital in the future to repay our convertible senior notes, and existing or future resources may not be available to us in sufficient amounts or on acceptable terms.

During November 2003, we completed a private offering of $100 million in aggregate principal amount of convertible senior notes due November 15, 2023 to qualified institutional buyers. The notes are convertible prior to maturity into shares of our common stock at a conversion price of $23.57 per share under certain circumstances that include but are not limited to (i) conversion due to the closing price of our common stock on the trading day prior to the conversion date reaching 120% or more of the conversion price of the notes on such trading date and (ii) conversion due to the trading price of the notes falling below 98% of the conversion value. Upon conversion we will have the right to deliver, in lieu of common stock, cash or a combination of cash and common stock. We may redeem all or a portion of the notes at our option on or after November 15, 2006 but before November 15, 2008 provided that the closing price of our common stock exceeds 130% of the conversion price for at least 20 trading days within a period of 30 consecutive trading days ending on the trading day before the date of the notice of the provisional redemption. As of September 30, 2007, the convertible senior notes were not redeemable at our option. On or after November 15, 2008, we may redeem the notes at any time. On November 15, 2008, November 15, 2013, and November 15, 2018, holders of the convertible senior notes will have the right to require us to purchase, in cash, all or any part of the notes held by such holder at a purchase price equal to 100% of the principal amount of the notes being purchased, together with accrued and unpaid interest and additional interest, if any, up to but excluding the purchase date.

10

As of September 30, 2007, we had outstanding convertible senior notes with a face value of $100 million. While we cannot predict whether or when holders of the convertible senior notes will choose to exercise their repurchase rights, we believe that they would become more likely to do so in the event that the price of our common stock is not greater than certain levels or if interest rates increase, or both. Therefore, if a substantial portion of the convertible senior notes were to be submitted for repurchase on any of the repurchase dates, we might need to use a substantial amount of our available sources of liquidity for this purpose. Consequently, such repurchase could have the effect of restricting our ability to fund new acquisitions or to meet other future working capital needs, as well as increasing our costs of borrowing. We may seek other means of refinancing or restructuring our obligations under the convertible senior notes, but this may result in terms less favorable than those under the existing convertible senior notes.

Other Risk Factors Related to Our Business

Other risk factors include, but are not limited to, changes in the mix of products sold, changes in regulatory and tax legislation, changes in effective tax rates, inventory risks due to changes in market demand or our business strategies, potential litigation and claims arising in the normal course of business, credit risk of customers and other risk factors. Additionally, proposed changes to accounting rules could materially affect what we report under GAAP and adversely affect our operating results.

RISKS RELATED TO OUR SECURITIES

We do not intend to pay dividends on our common stock.

We have never paid any cash dividends on our common stock and do not expect to declare cash dividends on the common stock in the foreseeable future in compliance with our policy to retain all of our earnings to finance future growth. Therefore, investors will not receive any funds unless they sell their common stock, and shareholders may be unable to sell their shares on favorable terms or at all. Investors cannot be assured of a positive return on investment or that they will not lose the entire amount of their investment in the common stock.

The price of our common stock may fluctuate significantly.

Our common stock is quoted on the Nasdaq Global Select Market under the symbol “RSYS.” The market prices of our securities are subject to significant fluctuations in response to the factors set forth above and other factors, many of which are beyond our control. Such fluctuations, as well as economic conditions generally, may adversely affect the market price of our securities, including our common stock and the debt securities.

A large number of shares of our common stock underlying options, restricted stock unit awards and convertible notes may be available for future sale and the sale of these shares may depress the market price of our common stock.

The issuance of shares of common stock upon the exercise of our outstanding options, restricted stock unit awards and convertible notes will result in dilution to the interests of our shareholders and you as an investor, and may have an adverse effect on the trading price and market for our common stock. As of September 30, 2007, we had options, restricted stock unit awards and convertible notes outstanding that may be exercised or converted at various times to require us to issue 7,844,000 shares, or approximately 35.3%, of our common stock on a fully diluted basis. The future sale of these shares may adversely affect the market price of our common stock. Shares issued upon exercise of our outstanding options, restricted stock unit awards and convertible notes will also cause immediate and substantial dilution to our existing shareholders. In addition, as long as these options, restricted stock unit awards and convertible notes remain outstanding, our ability to obtain additional capital through the sale of our securities might be adversely affected.

Future sales of shares of our common stock or the issuance of securities senior to our common stock could adversely affect the trading price of our common stock, the value of our debt securities and our ability to raise funds in new equity offerings.

We may issue additional common stock, preferred stock or securities convertible into or exchangeable for common stock, in the future. Future sales of substantial amounts of our common stock or equity-related securities in the public market or privately, or the perception that such sales could occur, could adversely affect prevailing trading prices of our common stock and the value of our debt securities and could impair our ability to raise capital through future offerings of equity or equity-related securities. No prediction can be made as to the effect, if any, that future sales of shares of common stock or the availability of shares of common stock for future sale, will have on the trading price of our common stock or the value of our debt securities.

11

Our board of directors may issue our authorized preferred stock without shareholder approval.

Our articles of incorporation authorize the issuance of up to 10,000,000 shares of preferred stock with rights and preferences that may be determined from time to time by our board of directors. Accordingly, our board of directors may, without shareholder approval, issue one or more series of preferred stock with rights which could adversely affect the voting power or other rights of the holders of outstanding shares of preferred stock or common stock. Although we do not have any current plans to issue any series or shares of preferred stock, we may do so in the future. Because the notes are convertible into shares of our common stock, the actual or potential issuance of preferred stock could result in a decrease in the trading price of the notes.

The future sales of restricted and other shares may cause dilution to each shareholder’s percentage ownership interest and could cause our stock price to decline.

Sales of a substantial amount of stock in the public market (such as the shares previously registered by us), or the perception that these sales may occur, could result in lower market prices of our common stock. This could also impair our ability to raise additional capital through the sale of other securities. As of September 30, 2007, we had 22,196,000 shares of common stock outstanding. We also have 3,601,000 shares of common stock issuable upon exercise of outstanding stock options and release of restricted stock units. Additionally, as of September 30, 2007 we have 5,903,000 shares of common stock available for future issuance under our stock plans and 1,507,000 shares of common stock reserved for future issuance under our employee stock purchase plan. All of these shares have been registered for sale. The issuance and sale of a significant number of shares of our securities upon the exercise of stock options, or the sales of a substantial number of shares of stock pursuant to Rule 144 or otherwise, could result in a dilution to each shareholder’s percentage ownership and could adversely affect the market prices of our securities.

If an active trading market does not develop for a series of debt securities sold pursuant to this prospectus, you may be unable to sell any such debt securities or to sell any such debt securities at a price that you deem sufficient.

Unless otherwise specified in an accompanying prospectus supplement, any debt securities sold pursuant to this prospectus will be new securities for which there currently is no established trading market. We may elect not to list any debt securities sold pursuant to this prospectus on a national securities exchange. While the underwriters of a particular offering of debt securities may advise us that they intend to make a market in those debt securities, the underwriters will not be obligated to do so and may stop their market making at any time. No assurance can be given:

• that a market for any series of debt securities will develop or continue;

• as to the liquidity of any market that does develop; or

• as to your ability to sell any debt securities you may own or the price at which you may be able to sell your debt securities.

Our management will have broad discretion over the use of the proceeds to us from any offering and might not apply the proceeds of an offering in ways that increase the value of your investment.

Our management will have broad discretion to use the net proceeds from any offering, and you will have to rely on the judgment of our management regarding the application of these proceeds. Our management might not apply the net proceeds of an offering in ways that you believe will increase the value of your investment. We will describe the expected use of net proceeds from an offering in the applicable prospectus supplement.

If our cash flows prove inadequate to service our debt and provide for our other obligations, we may be required to refinance all or a portion of our existing and future debt at terms unfavorable to us.

Our ability to make payments on and refinance our debt, and to fund our operations and capital expenditures will depend on our ability to generate substantial operating cash flow. If our cash flows prove inadequate to meet our debt service obligations, in the future, we may be required to refinance all or a portion of our existing or future debt, to sell assets or to obtain additional financing. We cannot assure you that any such refinancing or that any such sale of assets or additional financing would be possible on favorable terms, or at all. If we raise additional equity or equity-related securities in the future, it may be dilutive to holders of our common stock.

12

You should consider the U.S. federal income tax consequences of owning our securities.

There are risks associated with the U.S. federal income tax consequences of owning our debt securities and common stock. Because the tax consequences of owning our debt securities and common stock are complex and certain tax consequences may differ depending on the holder’s particular tax circumstances, each potential investor should consult with and rely on its own tax advisor about the tax consequences. In addition, there can be no assurance that the U.S. federal income tax treatment currently applicable to owning our debt securities and common stock will not be modified by legislative, administrative, or judicial action that may have a retroactive effect. No representation or warranty of any kind is made with respect to the acceptance by the Internal Revenue Service or any court of law regarding the treatment of any item of income, deduction, gain, loss or credit by an investor on its tax return.

The effect of the lending of our shares of common stock, including sales of our common stock in short sale transactions, may lower the market price of our common stock.

We may offer shares of our common stock for lending under share lending agreements. The effect of the lending of shares of our common stock could have a negative effect on the market price of our common stock.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock and certain provisions of our restated articles of incorporation and restated bylaws is a summary and is qualified in its entirety by the provisions of our articles of incorporation and bylaws.

Our authorized capital stock consists of 100,000,000 shares of common stock, no par value per share, and 10,000,000 shares of preferred stock, par value $0.01 per share. No shares of preferred stock are outstanding.

Common Stock

As of September 30, 2007, there were 22,196,000 shares of our common stock outstanding. Subject to preferences that may be applicable to any preferred stock outstanding at the time, the holders of our common stock have the following rights:

Dividends. Holders of our common stock are entitled to receive ratably such dividends on our common stock as may from time to time be declared by our board of directors out of funds legally available therefore.

Voting. Holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of shareholders, including the election of directors. Cumulative voting for the election of directors is not authorized by our articles of incorporation, which means that the holders of a majority of the shares voted can elect all of the directors then standing for election.

Preemptive Rights, Conversion and Redemption. Holders of our common stock have no preemptive rights and no right to redeem their common stock or convert their common stock into any other securities.

Liquidation, Dissolution and Winding-up. Upon our liquidation, dissolution or winding-up, the holders of our common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation rights of any preferred stock.

Preferred Stock

Our board of directors is authorized, without further action by our shareholders, to designate and issue up to 10,000,000 shares of preferred stock in one or more series. Our board of directors may fix the rights, preferences and privileges of the shares of each series and any qualifications, limitations or restrictions on these shares.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock.

The issuance of preferred stock could delay, defer or prevent a change of control of RadiSys. We have no current plans to issue any shares of preferred stock.

Oregon Control Share and Business Combination Statutes

Oregon law may restrict the ability of our significant shareholders to exercise voting rights. The Oregon Control Share Act generally applies to a person who acquires voting stock of an Oregon corporation in a transaction that results in that person holding more than one-fifth, one-third or one-half of the total voting power of the voting shares of the corporation. If such a transaction occurs, the person cannot vote the shares acquired in the acquisition unless voting rights are restored to those shares by:

• the holders of a majority of the outstanding voting shares of each voting group entitled to vote; and

• the holders of a majority of the outstanding voting shares, excluding the acquired shares and shares held by the corporation’s officers and inside directors.

This law is construed broadly and may apply to both companies and persons acting as a group.

The restricted shareholder may, but is not required to, submit to the corporation a statement setting forth information about itself and its plans with respect to the corporation. The statement may request that the corporation call a special meeting of

16

shareholders to determine whether voting rights will be granted to the shares acquired. If a special meeting of shareholders is not requested, the issue of voting rights of the acquired shares will be considered at the next annual or special meeting of shareholders that is held more than 60 days after the date the shares are acquired. If the acquired shares are granted voting rights and they represent a majority of all voting power, shareholders who do not vote in favor of granting voting rights will be entitled to dissent and will have the right to receive the fair value of their shares if the shareholders follow the provisions of Oregon’s dissenters’ rights statute. The fair value will, at a minimum, be equal to the highest price paid per share by the person for the shares acquired in the transaction subject to this law.

We are also subject to provisions of Oregon law that govern business combinations between corporations and interested shareholders. The Oregon Business Combination Act generally prohibits a corporation from entering into a business combination transaction with a person, or an affiliate of that person, for a period of three years following the date the person acquires 15% or more of the voting stock of the corporation. For the purposes of this law, the prohibition generally applies to the following business combination transactions:

• a merger or plan of share exchange,

• any sale, lease, mortgage or other disposition of 10% or more of the assets of the corporation, and

• transactions that result in the issuance of capital stock of the corporation to the 15% shareholder.

However, the general prohibition does not apply if:

• the 15% shareholder, as a result of the transaction in which the person became a 15% shareholder, owns at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding shares owned by directors who are also officers, and certain employee benefit plans),

• the board of directors approves the share acquisition or business combination before the shareholder acquired 15% or more of the corporation’s outstanding voting stock, or

• the board of directors and the holders of at least 66 2/3% of the outstanding voting stock of the corporation, excluding shares owned by the 15% shareholder, approve the transaction on or after the date the shareholder acquires 15% or more of the corporation’s voting stock.

Advance Notice Provisions. Our bylaws establish advance notice procedures for shareholder proposals and nominations of candidates for election as directors other than nominations made by or at the direction of our board of directors or a committee of our board.

Special Meeting Requirements. Our bylaws require that special meetings of shareholders be called at the request of our board of directors.

Cumulative Voting. Neither our articles of incorporation nor our bylaws provide for cumulative voting in the election of directors.

These provisions may deter a hostile takeover or delay a change of control or management of RadiSys.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Mellon Shareholder Services, L.L.C.

Nasdaq Stock Market Quotation

Our common stock is traded on the Nasdaq Global Select Market under the symbol “RSYS.”

DESCRIPTION OF PREFERRED STOCK

We may issue preferred stock in series with any rights and preferences which may be authorized by our board of directors. We will distribute a prospectus supplement with regard to each particular series of preferred stock. Each prospectus supplement will describe, as to the series of preferred stock to which it relates:

• the title of the series of preferred stock;

17

• any limit upon the number of shares of the series of preferred stock which may be issued;

• the preference, if any, to which holders of the series of preferred stock will be entitled upon our liquidation;

• the date or dates on which we will be required or permitted to redeem the preferred stock;

• the terms, if any, on which we or holders of the preferred stock will have the option to cause the preferred stock to be redeemed or purchased;

• the voting rights, if any, of the holders of the preferred stock;

• the dividends, if any, which will be payable with regard to the series of preferred stock, which may be fixed dividends or participating dividends and may be cumulative or non-cumulative;

• the right, if any, of holders of the preferred stock to convert it into another class of our stock or securities, including provisions intended to prevent dilution of those conversion rights;

• any provisions by which we will be required or permitted to make payments to a sinking fund to be used to redeem preferred stock or a purchase fund to be used to purchase preferred stock; and

• any other material terms of the preferred stock.

Holders of shares of preferred stock will not have preemptive rights.

DESCRIPTION OF DEPOSITARY SHARES

General. We may, at our option, elect to offer fractional shares of preferred stock, rather than full shares of preferred stock. If we exercise this option, we will issue to the public receipts for depositary shares, and each of these depositary shares will represent a fraction (to be set forth in the applicable prospectus supplement) of a share of a particular series of preferred stock.

The shares of any series of preferred stock underlying the depositary shares will be deposited under a deposit agreement between us and a bank or trust company selected by us. The depositary will have its principal office in the United States and a combined capital and surplus of at least $50,000,000. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, in proportion, to the applicable fraction of a share of preferred stock underlying that depositary share, to all the rights and preferences of the preferred stock underlying that depositary share. Those rights include dividend, voting, redemption and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of preferred stock underlying the depositary shares, in accordance with the terms of the offering. Copies of the forms of deposit agreement and depositary receipt will be filed as exhibits to the registration statement. The following summary of the deposit agreement, the depositary shares and the depositary receipts is not complete. You should refer to the forms of the deposit agreement and depositary receipts that will be filed with the SEC in connection with the offering of the specific depositary shares.

Pending the preparation of definitive engraved depositary receipts, the depositary may, upon our written order, issue temporary depositary receipts substantially identical to the definitive depositary receipts but not in definitive form. These temporary depositary receipts entitle their holders to all the rights of definitive depositary receipts which are to be prepared without unreasonable delay. Temporary depositary receipts will then be exchangeable for definitive depositary receipts at our expense.

Dividends and Other Distributions. The depositary will distribute all cash dividends or other cash distributions received with respect to the preferred stock to the record holders of depositary shares relating to the preferred stock in proportion to the number of depositary shares owned by those holders.

If there is a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary shares that are entitled to receive the distribution, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the applicable holders.

18

Redemption of Depositary Shares. If a series of preferred stock represented by depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of that series of preferred stock held by the depositary. The redemption price per depositary share will be equal to the applicable redemption fraction of the redemption price per share payable with respect to that series of the preferred stock. Whenever we redeem shares of preferred stock that are held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing the shares of preferred stock so redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as may be determined by the depositary.

Voting the Preferred Stock. Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in such notice to the record holders of the depositary shares underlying the preferred stock. Each record holder of the depositary shares on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of the preferred stock represented by the holder’s depositary shares. The depositary will then try, as far as practicable, to vote the number of shares of preferred stock underlying those depositary shares in accordance with such instructions. We will agree to take all actions which may be deemed necessary by the depositary to enable the depositary to do so. The depositary will not vote the shares of preferred stock to the extent it does not receive specific instructions from the holders of depositary shares underlying the preferred stock.

Amendment and Termination of the Depositary Agreement. The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may at any time be amended by agreement between us and the depositary. However, any amendment which materially and adversely alters the rights of the holders of depositary shares will not be effective unless the amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The deposit agreement may be terminated by us or by the depositary only if (a) all outstanding depositary shares have been redeemed or (b) there has been a final distribution of the underlying preferred stock in connection with our liquidation, dissolution or winding up and the preferred stock has been distributed to the holders of depositary receipts.

Charges of Depositary. We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will also pay charges of the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay other transfer and other taxes and governmental charges and those other charges, including a fee for the withdrawal of shares of preferred stock upon surrender of depositary receipts, as are expressly provided in the deposit agreement to be for their accounts.

Miscellaneous. The depositary will forward to holders of depositary receipts all reports and communications from us that we deliver to the depositary and that we are required to furnish to the holders of the preferred stock.

Neither we nor the depositary will be liable if either of us is prevented or delayed by law or any circumstance beyond our control in performing our respective obligations under the deposit agreement. Our obligations and those of the depositary will be limited to performance in good faith of our respective duties under the deposit agreement. Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the depositary may rely upon written advice of counsel or accountants, or upon information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine.

Resignation and Removal of Depositary. The depositary may resign at any time by delivering notice to us of its election to resign. We may remove the depositary at any time. Any resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of the appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of debt securities, preferred stock, common stock, or units of two or more of these types of securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any registered holders of warrants or beneficial owners of warrants.

19

We will distribute a prospectus supplement with regard to each issue of warrants. Each prospectus supplement will describe:

• in the case of warrants to purchase debt securities, the designation, aggregate principal amount, currencies, denominations and terms of the series of debt securities purchasable upon exercise of the warrants and the price at which you may purchase the debt securities upon exercise;

• in the case of warrants to purchase preferred stock, the designation, number of shares, stated value and terms, such as liquidation, dividend, conversion and voting rights, of the series of preferred stock purchasable upon exercise of the warrants and the price at which you may purchase such number of shares of preferred stock of such series upon such exercise;

• in the case of warrants to purchase common stock, the number of shares of common stock purchasable upon the exercise of the warrants and the price at which you may purchase such number of shares of common stock upon such exercise;

• the period during which you may exercise the warrants;

• any provision adjusting the securities that may be purchased on exercise of the warrants, and the exercise price of the warrants, to prevent dilution or otherwise;

• the place or places where warrants can be presented for exercise or for registration of transfer or exchange; and

• any other material terms of the warrants.

Warrants for the purchase of preferred stock and common stock will be offered and exercisable for U.S. dollars only. Warrants will be issued in registered form only. The exercise price for warrants will be subject to adjustment as described in the applicable prospectus supplement.

Prior to the exercise of any warrants to purchase debt securities, preferred stock or common stock, holders of the warrants will not have any of the rights of holders of the debt securities, preferred stock or common stock purchasable upon exercise, including:

• in the case of warrants for the purchase of debt securities, the right to receive payments of principal of, any premium or interest on the debt securities purchasable upon exercise or to enforce covenants in the applicable indenture; or

• in the case of warrants for the purchase of preferred stock or common stock, the right to vote or to receive any payments of dividends on the preferred stock or common stock purchasable upon exercise.

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities under an indenture to be entered into between us and a trustee chosen by us, qualified to act as such under the Trust Indenture Act and appointed in a supplemental indenture with respect to a particular series. We will identify such trustee in a prospectus supplement. The indenture, as supplemented by a supplemental indenture, is governed by the Trust Indenture Act.

The following is a summary of certain provisions of the indenture. It does not restate the indenture entirely. We urge you to read the indenture. We have filed the indenture as an exhibit to the registration statement of which this prospectus is a part. References below to an “indenture” are references to the indenture, as supplemented by a supplemental indenture, under which a particular series of debt securities is issued.

Terms of the Debt Securities

Our debt securities will be unsecured obligations of the Company. We may issue them in one or more series. The indenture does not limit the amount of debt securities that may be issued. Authorizing resolutions or a supplemental indenture will set forth the specific terms of each series of debt securities. We will provide a prospectus supplement for each series of debt securities that will describe:

• the title of the debt securities and whether the debt securities are senior, senior subordinated, or subordinated debt securities;

20

• the aggregate principal amount of the debt securities and any limit upon the aggregate principal amount of the series of debt securities;

• the date or dates on which principal of the debt securities will be payable and the amount of principal which will be payable;

• the rate or rates (which may be fixed or variable) at which the debt securities will bear interest, if any, as well as the dates from which interest will accrue, the dates on which interest will be payable and the record date for the interest payable on any payment date;

• whether and under what circumstances any additional amounts are payable with respect to debt securities;

• the currency or currencies in which principal, premium, if any, and interest, if any, will be payable;

• the place or places where principal, premium, if any, and interest, if any, on the debt securities will be payable and where debt securities which are in registered form can be presented for registration of transfer or exchange; and the identification of any depositary or depositaries for any global debt securities;

• any provisions regarding our right to redeem or purchase debt securities or the right of holders to require us to redeem or purchase debt securities;

• the right, if any, of holders of the debt securities to convert them into our common stock or other securities, including any provisions intended to prevent dilution of the conversion rights;

• any provisions requiring or permitting us to make payments to a sinking fund to be used to redeem debt securities or a purchase fund to be used to purchase debt securities;

• the percentage of the principal amount at which debt securities will be issued and, if other than the full principal amount thereof, the percentage of the principal amount of the debt securities which is payable if maturity of the debt securities is accelerated because of a default;

• the terms, if any, upon which debt securities may be subordinated to our other indebtedness;

• any additions to, modifications of or deletions from the terms of the debt securities with respect to events of default or covenants or other provisions set forth in the indenture; and

• any other material terms of the debt securities, which may be different from the terms set forth in this prospectus.

The applicable prospectus supplement will also describe any material covenants to which a series of debt securities will be subject.

Events of Default and Remedies

Unless otherwise described in the prospectus supplement, an event of default with respect to any series of debt securities will be defined in the indenture or applicable supplemental indenture as being:

• default in payment of the principal of or premium, if any, or any additional amounts with respect to such principal or premium, on any of the debt securities of such series;

• default for 30 days in payment of any installment of interest or any additional amounts with respect to such interest on any debt security of such series beyond any applicable grace period;

• default in the payment, if any, of any sinking fund installment when and as due by the terms of any debt security of such series, subject to any cure period that may be specified in any debt security of such series;

• failure to perform any other covenant or warranty of our Company contained in such indenture or such debt securities continued for 90 days after written notice;

21

• bankruptcy, insolvency or reorganization of our Company; and

• any other event of default provided in a supplemental indenture with respect to a particular series of debt securities.

The indenture will provide that the trustee may withhold notice to the holders of any series of debt securities of any default, except a default in payment of principal, premium, if any, or interest, if any, with respect to such series of debt securities, if the trustee considers it in the interest of the holders of such series of debt securities to do so.

The indenture will provide that if any event of default has occurred, except for bankruptcy, insolvency or reorganization of the Company, and is continuing with respect to any series of debt securities, the trustee or the holders of not less than 25% in principal amount of such series of debt securities then outstanding may declare the principal of all the debt securities of such series to be due and payable immediately. If an event of default resulting from bankruptcy, insolvency or reorganization of the Company shall occur and be continuing then the principal amount (or, in the case of discounted debt securities, the amount specified in the terms thereof) of all the debt securities outstanding shall be and become due and payable immediately, without notice or other action by any holder or the applicable trustee, to the full extent permitted by law. However, the holders of a majority in principal amount of the debt securities of such series then outstanding by written notice to the trustee and to us may waive any event of default with respect to such series of debt securities, other than any event of default in payment of principal or premium, if any, or interest, or additional amounts. Holders of a majority in principal amount of the then outstanding debt securities of any series may rescind an acceleration with respect to such series and its consequences, except an acceleration due to nonpayment of principal or premium, if any, or interest, or additional amounts on such series, if the rescission would not conflict with any judgment or decree and if all existing events of default with respect to such series have been cured or waived.

The holders of a majority of the outstanding principal amount of the debt securities of any series will have the right to direct the time, method and place of conducting any proceedings for any remedy available to the trustee with respect to such series, subject to limitations specified in the indenture; provided, however, that the applicable trustee may decline to follow any such direction if, among other reasons, the applicable trustee determines in good faith that the actions or proceedings as directed may not lawfully be taken or would be unduly prejudicial to the holders of the debt securities of such series not joining in such direction. The right of a holder to institute a proceeding with respect to the applicable indenture will be subject to certain conditions precedent including, without limitation, that the holders of not less than 25% in aggregate principal amount of the debt securities of such series then outstanding under such indenture make a written request upon the applicable trustee to exercise its powers under such indenture, indemnify the applicable trustee and afford the applicable trustee reasonable opportunity to act, but the holder has an absolute right to receipt of the principal of, premium, if any, and interest when due on the debt securities, to require conversion of debt securities if such indenture provides for convertibility at the option of the holder and to institute suit for the enforcement thereof.

Defeasance

The indenture will permit us to terminate all our respective obligations under the indenture as they relate to any particular series of debt securities, other than the obligation to pay interest, if any, on and the principal of the debt securities of such series and certain other obligations, at any time if:

• (i) all debt securities of such series previously authenticated and delivered, with certain exceptions, have been accepted by the applicable trustee for cancellation, or (ii) the debt securities of such series have become due and payable, or mature within one year, or all of them are to be called for redemption within one year under arrangements satisfactory to the applicable trustee for giving the notice of redemption;

• the Company irrevocably deposits in trust with the applicable trustee, as trust funds solely for the benefit of the holders of such debt securities, for that purpose, money sufficient to pay the entire indebtedness on the debt securities of such series to maturity or redemption, as the case may be, and to pay all other sums payable by it under such indenture; and

• the Company delivers to the applicable trustee an officers’ certificate and an opinion of counsel, in each case stating that all conditions precedent provided for in such indenture relating to the satisfaction and discharge of such indenture with respect to the debt securities of such series have been complied with.

With respect to the foregoing clauses (i) and (ii), certain obligations of the Company to the trustee shall survive. With respect to the foregoing clause (ii), the Company’s obligations to execute and deliver debt securities of such series for authentication, to maintain an office or agency in respect of the debt securities of such series, to have moneys held for payment in trust, to register the transfer or exchange of debt securities of such series, to deliver debt securities of such series for replacement, to pay additional

22

amounts, if any, in certain circumstances, and with respect to rights of conversion or exchange, if any, shall survive until such debt securities are no longer outstanding. Thereafter, only the Company’s obligations to compensate and indemnify the applicable trustee and its right to recover excess money held by the applicable trustee shall survive.

The indenture further provides that the Company (i) will be deemed to have paid and will be discharged from any and all obligations in respect of the debt securities issued thereunder of any series, and the provisions of such indenture will, except as noted below, no longer be in effect with respect to the debt securities of such series and (ii) may omit to comply with any term, provision, covenant or condition of such indenture with respect to the outstanding debt securities of such series; provided that the following conditions shall have been satisfied:

• the Company has irrevocably deposited in trust with the applicable trustee as trust funds solely for the benefit of the holders of the debt securities of such series, for payment of the principal of and interest of the debt securities of such series, money or government obligations or a combination thereof sufficient (in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the applicable trustee) without consideration of any reinvestment to pay and discharge the principal of and accrued interest on the outstanding debt securities of such series to maturity or earlier redemption (irrevocably provided for under arrangements satisfactory to the applicable trustee), as the case may be;

• such deposit will not result in a breach or violation of, or constitute a default under, such indenture or any other material agreement or instrument to which the Company is a party or by which it is bound;

• no default with respect to such debt securities of such series shall have occurred and be continuing on the date of such deposit;

• the Company shall have delivered to such trustee an opinion of counsel as described in the indenture to the effect that (1) the holders of the debt securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of the Company’s exercise of its option under this provision of such indenture and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred, and (2) after the 91st day after the establishment of such trust, the amounts in such trust will not be subject to any case or proceeding in respect of the Company under applicable bankruptcy, insolvency or similar law; and

• the Company has delivered to the applicable trustee an officers’ certificate and an opinion of counsel, in each case stating that all conditions precedent provided for in such indenture relating to the defeasance contemplated have been complied with.

Subsequent to a legal defeasance under clause (i) above, the Company’s obligations to execute and deliver debt securities of such series for authentication, to maintain an office or agency in respect of the debt securities of such series, to have moneys held for payment in trust, to register the transfer or exchange of debt securities of such series, to deliver debt securities of such series for replacement, to pay additional amounts, if any, in certain circumstances, and with respect to rights of conversion or exchange, if any, shall survive until such debt securities are no longer outstanding.

Transfer and Exchange

A holder will be able to transfer or exchange debt securities only in accordance with the indenture. The registrar may require a holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or permitted by the indenture.

Amendment, Supplement and Waiver

The indenture provides that supplements to the indenture and the applicable supplemental indentures may be made by the Company and the trustee for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture or of modifying in any manner the rights of the holders of debt securities of a series under the indenture or the debt securities of such series. Without the consent of any holder, we and the trustee may amend or supplement the indenture, the debt securities to:

• cure any ambiguity, defect or inconsistency;

23

• create a series and establish its terms;

• provide for uncertificated debt securities in addition to or in place of certificated debt securities;

• evidence the succession of another corporation to the Company and the assumption by any such successor of the covenants of the Company in such indenture and in the debt securities issued thereunder;

• add to the covenants of the Company or to surrender any right or power conferred on the Company pursuant to the indenture;

• to evidence and provide for a successor trustee under such indenture with respect to one or more series of debt securities issued thereunder or to provide for or facilitate the administration of the trusts under such indenture by more than one trustee;

• add to, delete from or revise the conditions, limitations and restrictions on the authorized amount, terms or purposes of issue, authentication and delivery of securities under the indenture,

• add any additional events of default with respect to all or any series of debt securities;

• supplement any of the provisions of the indenture as may be necessary to permit or facilitate the defeasance and discharge of any series of debt securities, provided that such action does not adversely affect the interests of any holder of an outstanding debt security of such series or any other security in any material respect;

• make provisions with respect to the conversion or exchange rights of holders of debt securities of any series;

• qualify such indenture under the Trust Indenture Act of 1939; or

• make any change that does not adversely affect the legal rights of any holder.

With the exceptions discussed below, we and the trustee may amend or supplement the indenture or the debt securities of a particular series with the consent of the holders of at least a majority in principal amount of the debt securities of such series then outstanding. In addition, the holders of a majority in principal amount of the debt securities of such series then outstanding may waive any existing default under, or compliance with, any provision of the indenture relating to a particular series of debt securities, other than any event of default in payment of interest or principal, or additional amounts. These consents and waivers may be obtained in connection with a tender offer or exchange offer for debt securities.

Without the consent of each holder affected, we and the trustee may not:

• reduce the amount of debt securities of such series whose holders must consent to an amendment, supplement or waiver;

• reduce the rate of or change the time for payment of interest;

• reduce the principal of or change the fixed maturity of any debt security or alter the provisions with respect to redemptions or mandatory offers to repurchase debt securities;

• make any debt security payable at a place or in money other than that stated in the debt security;

• modify the ranking or priority of the debt securities;

• waive a continuing default in the payment of principal of or interest on the debt securities; or

• make any change that adversely affects the right to convert or exchange any security into or for common stock or other securities, cash or other property in accordance with the terms of the applicable debt security.

The right of any holder to participate in any consent required or sought pursuant to any provision of the indenture, and our obligation to obtain any such consent otherwise required from such holder, may be subject to the requirement that such holder shall have been the holder of record of debt securities with respect to which such consent is required or sought as of a date identified by the trustee in a notice furnished to holders in accordance with the indenture.

24

Concerning the Trustee

In the ordinary course of its business, the trustee, when selected, may provide services to us as transfer agent for our common stock and trustee under indentures relating to our senior notes and senior subordinated notes. The indenture contains, or will contain, limitations on the rights of the trustee, should it become our creditor, to obtain payment of claims in specified cases or to realize on property received in respect of any such claim as security or otherwise. The indenture permits, or will permit, the trustee to engage in other transactions; however, if it acquires any conflicting interest, it must eliminate such conflict or resign.

The indenture provides, or will provide, that in case an event of default occurs and is not cured, the trustee will be required, in the exercise of its power, to use the degree of care of a prudent person in similar circumstances in the conduct of such person’s own affairs. The trustee may refuse to perform any duty or exercise any right or power under the indenture, unless it receives indemnity satisfactory to it against any loss, liability or expense.

The indenture provides that the applicable trustee may withhold notice to the holders of any default with respect to any series of debt securities (except in payment of principal of or interest or premium on, or sinking fund payment in respect of, the debt securities) if the applicable trustee considers it in the interest of holders to do so.

The indenture contains a provision entitling the applicable trustee to be indemnified by the holders before proceeding to exercise any trust or power under such indenture at the request of such holders.

Certain Covenants

Existence. Except as permitted under “— Consolidation, Merger and Sale of Assets,” the indenture requires the Company to do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, rights (by certificate of incorporation, bylaws and statute) and franchises; provided, however, that the Company will not be required to preserve any right or franchise if the Company determines that the preservation thereof is no longer desirable in the conduct of its business.

Calculation of Original Issue Discount. The Company shall file with the trustee promptly at the end of each calendar year a written notice specifying the amount of original issue discount accrued on outstanding securities at the end of such year and any other specific information as may then be relevant under the Internal Revenue Code of 1986, as amended.

Additional Covenants. Any additional covenants of the Company with respect to any series of debt securities will be set forth in the prospectus supplement relating thereto.

Repurchases on the Open Market

The Company or any affiliate of the Company may at any time or from time to time repurchase any debt security in the open market or otherwise. Such debt securities may, at the option of the Company or the relevant affiliate of the Company, be held, resold or surrendered to the trustee for cancellation.

Governing Law

The laws of the State of New York will govern the indenture and the debt securities.

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement, units will consist of one or more warrants, debt securities, preferred stock, common stock, or any combination thereof. You should refer to the applicable prospectus supplement for:

• all terms of the warrants, debt securities, shares of preferred stock or shares of common stock or any combination thereof comprising the units, including whether and under what circumstances the securities comprising the units may or may not be traded separately;

• a description of the terms of any unit agreement governing the units; and

• a description of the provisions for the payment, settlement, transfer or exchange of the units.

25

PLAN OF DISTRIBUTION

We may sell the offered securities in and outside the United States in any of the following ways:

• directly to investors or to other purchasers, including our existing shareholders in a rights offering;

• through agents;

• through dealers;

• through one or more underwriters or a syndicate of underwriters in an underwritten offering; or

• through a combination of any of these methods.

The prospectus supplement will include the following information:

• the terms of the offering;

• the names of any underwriters, dealers or agents;

• the name or names of any managing underwriter or underwriters;

• the purchase price or initial public offering price of the securities;

• the net proceeds from the sale of the securities;

• any delayed delivery arrangements;

• any underwriting discounts, commissions and other items constituting underwriters’ compensation;

• any discounts or concessions allowed or reallowed or paid to dealers; and

• any commissions paid to agents.

We have reserved the right to sell the securities directly to investors, including persons who may be deemed to be underwriters within the meaning of the Securities Act, on our own behalf, in those jurisdictions where we are authorized to do so. We may also sell securities upon the exercise of rights that we may issue to our security holders. In these cases, no underwriters or agents would be involved. The sale of the securities may be effected in transactions (a) on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, (b) in the over-the-counter market, (c) in transactions otherwise than on such exchanges or in the over-the-counter market or (d) through the writing of options.

We and our agents and underwriters, may offer and sell the securities at a fixed price or prices, which may be changed, or from time to time at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. We may, from time to time, authorize dealers, acting as our agents, to offer and sell the securities upon such terms and conditions as set forth in the applicable prospectus supplement.

In connection with offerings of securities, we may enter into derivative transactions with third parties in connection with which such third parties may sell common stock registered hereunder including in short sale transactions.

If we use underwriters to sell securities, we may enter into an underwriting agreement with them at the time of the sale to them. In connection with the sale of the securities, underwriters may receive compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of the securities for whom they may act as agent. Underwriters may sell the securities from time to time in one or more transactions, including negotiated transactions, to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions (which may be changed from time to time) from the purchasers for whom they may act as agents. The underwriters may also offer the securities through underwriting syndicates represented by one or more managing underwriters or directly by on or more firms acting as underwriters.

Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase the securities as a principal, and may then resell such securities at varying prices to be determined by the dealer.

Certain of the underwriters, dealers or agents and their associates may engage in transactions with, and perform services for, us and certain of our affiliates in the ordinary course of their business. Unless otherwise stated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

26

If so indicated in the prospectus supplement, we will authorize underwriters, dealers or agents to solicit offers by certain specified institutions to purchase offered securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject to any conditions set forth in the applicable prospectus supplement and the prospectus supplement will set forth the commission payable for solicitation of such contracts.

During and after an offering through underwriters, the underwriters may purchase and sell securities in the open market. To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the price of the securities. These may include over-allotment, stabilization, syndicate short covering transactions and penalty bids. These transactions may cause the price of the securities sold in an offering to be higher than it would otherwise prevail in the open market. If commenced, the underwriter may discontinue these activities at any time. Those transactions may include:

• Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

• Over-allotment transactions involve sales by the underwriters of shares in excess of the number of shares the underwriters are obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriters is not greater than the number of shares that they may purchase in the over-allotment option. In a naked short position, the number of shares involved is greater than the number of shares in the over-allotment option. The underwriters may close out any covered short position by either exercising their over-allotment option and/or purchasing shares in the open market.

• Syndicate covering transactions involve purchases of the common stock in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. If the underwriters sell more shares than could be covered by the over- allotment option, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

• Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of the offered securities or preventing or retarding a decline in the market price of the offered securities. As a result, the price of the offered securities may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the Nasdaq Global Select Market or otherwise and, if commenced, may be discontinued at any time.

If we use dealers in the sale of securities, the securities will be sold directly to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. Underwriters, dealers and agents may be entitled, under agreements entered into with us to indemnification against and contribution towards certain civil liabilities, including any liabilities under the Securities Act.

Any securities other than our common stock issued hereunder may be new issues of securities with no established trading market. Any underwriters or agents to or through whom such securities are sold for public offering and sale may make a market in such securities, but such underwriters or agents will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the trading market for any such securities.

EXPERTS

The consolidated financial statements of Radisys Corporation as of December 31, 2006 and 2005, and for each of the years in the two-year period ended December 31, 2006, and management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2006 incorporated by reference herein in reliance upon the report of KPMG LLP, independent registered public accounting firm, and upon the authority of said firm as experts in accounting and auditing.

Their report states that we changed our method of consideration for prior period misstatements and changed our method for accounting for share-based payment awards in 2006.

Their report dated March 1, 2007, on management’s assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting as of December 31, 2006 contains an explanatory paragraph that states we acquired Convedia Corporation during 2006, and we excluded from our assessment of the effectiveness of our internal control over financial reporting Convedia Corporation’s internal control over financial reporting associated with total assets of $11,522,000, exclusive of acquired goodwill of $39,720,000 and acquired identifiable intangible assets of $41,501,000, and total revenues of $5,887,000 included in the consolidated financial statements of the Company and subsidiaries as of and for the year ended December 31, 2006. Their audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Convedia Corporation.

The financial statements incorporated in this prospectus by reference to the Annual Report on Form 10-K for the year ended December 31, 2004 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

Item 15. Indemnification of Directors and Officers

Article VII of the Company’s Second Restated Articles of Incorporation and Article V of the Company’s Restated Bylaws require indemnification of current or former directors of the Company to the fullest extent permitted by law. The right to and amount of indemnification will ultimately be subject to determination by a court that indemnification in the circumstances presented is consistent with public policy and other provisions of law. However, it is likely that Article VII of the Company’s Second Restated Articles of Incorporation and Article V of the Company’s Restated Bylaws would require indemnification at least to the extent that indemnification is authorized by the Oregon Business Corporation Act. The effect of the indemnification provisions contained in Article VII of the Company’s Second Restated Articles of Incorporation, Article V of the Company’s Restated Bylaws and the Oregon Business Corporation Act (the “indemnification provisions”) is summarized as follows:

(a) The indemnification provisions grant a right of indemnification in respect of any action, suit or proceeding (other than an action by or in the right of the Company) against expenses (including attorney fees), judgments, fines and amounts paid in settlement actually and reasonably incurred, if the person concerned acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company, was not adjudged liable on the basis of receipt of an improper personal benefit and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful. The termination of an action, suit or proceeding by judgment, order, settlement, conviction or plea of nolo contendere does not, of itself, create a presumption that the person did not meet the required standards of conduct.

(b) The indemnification provisions grant a right of indemnification in respect of any action or suit by or in the right of the Company against the expenses (including attorney fees) actually and reasonably incurred if the person concerned acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company, except that no right of indemnification will be granted if the person is adjudged to be liable to the Company.

(c) Every person who has been wholly successful on the merits of a controversy described in (a) or (b) above is entitled to indemnification as a matter of right.

(d) The Company may not indemnify a director unless it is determined by (1) a majority of a quorum of disinterested directors or a committee of disinterested directors, (2) independent legal counsel or (3) the shareholders that indemnification is proper because the applicable standard of conduct has been met. Indemnification can also be ordered by a court if the court determines that indemnification is fair in view of all of the relevant circumstances.

(e) The Company will advance to a director the expenses incurred in defending any action, suit or proceeding in advance of its final disposition if the director affirms in good faith that he has met the standard of conduct to be entitled to indemnification as described in (a) or (b) above and undertakes to repay any amount advanced if it is determined that the person did not meet the required standard of conduct.

II-1

Under the Oregon Business Corporation Act, an officer of the Company is entitled to mandatory indemnification to the same extent as a director of the Company if he was wholly successful on the merits of a controversy described in (a) or (b) above.

The Company has entered into indemnity agreements with each of its officers and directors. The agreements provide that the Company shall indemnify an officer of director if he or she is a party to or threatened to be made a party to any proceeding (other than a proceeding by or in the right of the Company to procure a judgment in its favor) against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by the officer or director in connection with the proceeding, but only if he or she acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal proceeding, in addition, had no reasonable cause to believe that his or her conduct was unlawful.

Under the indemnity agreements, the Company shall also indemnify an officer or director if he or she is a party to or threatened to be made a party to any proceeding by or in the right of the Company to procure a judgment in its favor against all expenses actually and reasonably incurred by the officer or director in connection with the defense or settlement of the proceeding, but only if the officer or director acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company. Provided, however, no indemnification for expenses shall be made in respect of any claim, issue or matter as to which the officer or director shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that a court determines that the officer or director is fairly and reasonably entitled to indemnity.

Notwithstanding the foregoing, the indemnity agreements also provide that the Company shall indemnify an officer or director to the fullest extent permitted by law if the officer or director is a party to or threatened to be made a party to any proceeding (including a proceeding by or in the right of the Company to procure a judgment in its favor) against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by the officer or director in connection with the proceeding. Provided, however, no indemnity shall be made under this provision on account of conduct by the officer or director which constitutes a breach of his or her duty of loyalty to the Company or its shareholders or is an act or omission not in good faith or which involves intentional misconduct or a knowing violation of the law.

Additionally, the Company shall indemnify an officer or director to the fullest extent permitted by law if he or she is a party to or threatened to be made a party to any proceeding (including a proceeding by or in the right of the Company to procure a judgment in its favor) against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by the officer or director in connection with the proceeding.

The Company shall pay the expenses incurred by an officer or director in any proceeding in advance if the officer or director provides certain information and undertakings.

As used in the indemnity agreements, the term “proceeding” includes any threatened, pending or completed action, suit or proceeding, whether brought in the right of the Company or otherwise and whether of a civil, criminal, administrative or investigative nature, in which the officer or director may be or may have been involved as a party or otherwise by reason of the fact that he or she is or was a director or officer of the Company or is or was serving at the request of the Company as a director, officer, or agent of another corporation, partnership, joint venture, trust or other enterprise, whether or not serving in such capacity at the time any liability or expense is incurred for which indemnification or reimbursement can be provided under the agreement.

As used in the indemnity agreements, the term “expenses” includes, without limitation, expense of investigations, judicial or administrative proceedings or appeals, attorneys’ fees and disbursements and any expenses of establishing a right to indemnification under the indemnity agreement, but does not include amounts paid in settlement by an officer or director or the amount of judgments or fines against him or her.

II-2

The Company has obtained insurance for the protection of its directors and officers against any liability asserted against them in their official capacities. The Company has also entered into indemnification agreements with certain of the Company’s directors. The indemnification agreements in part incorporate the indemnification provisions of the Oregon Business Corporation Act as described above. The indemnification provisions also alter or clarify the statutory indemnity in certain respects. The most significant effects of the indemnification agreements are to add indemnification for settlements of derivative lawsuits and for proceedings involving a breach of fiduciary duty, subject to specified exceptions. The indemnification agreements also set forth certain procedures that apply in the event of a claim for indemnification or advancement of expenses.

The rights of indemnification described above are not exclusive of any other rights of indemnification to which the persons indemnified may be entitled under any bylaw, agreement, vote of shareholders or otherwise.

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that the undertakings set forth in paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-4

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted for our directors, officers and controlling persons pursuant to our Articles of Incorporation or Amended and Restated Bylaws, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by us of expenses incurred or paid by a director, officer, or controlling person in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by the registrant is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(d) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Trust Indenture Act.

(3) The ownership, principal amount and serial numbers of Registered Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, shall be proved by the Security Register.

(4) If the Company shall solicit from the Holders of any Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may at its option (but is not obligated to), by Board Resolution, fix in advance a record date for the determination of Holders of Registered Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of Registered Securities of record at the close of business on such record date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders of Registered Securities shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

11

(5) Any request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done or suffered to be done by the Trustee, any Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Security.

Section 1.5 Notices, etc. to Trustee and Company.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1) the Trustee by any Holder or the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing (which may be via facsimile) to or with the Trustee at its Corporate Trust Office, or

(2) the Company by the Trustee or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to the attention of its Treasurer (with a copy to the General Counsel) at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company.

Section 1.6 Notice to Holders of Securities; Waiver.

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of any event, such notice shall be sufficiently given to Holders of Registered Securities if in writing and mailed, first-class postage prepaid, to each Holder of a Registered Security affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities given as provided herein. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In the case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

12

Section 1.7 Language of Notices.

Any request, demand, authorization, direction, notice, consent, election or waiver required or permitted under this Indenture shall be in the English language, except that, if the Company so elects, any published notice may be in an official language of the country of publication (with a copy in English to be provided to the Trustee).

(a) If any provision hereof limits, qualifies or conflicts with the duties that would be imposed by any of Sections 310 to 317 of the TIA through operation of Section 318(c) thereof on any person if this Indenture were qualified under the TIA, such imposed duties shall control.

All other TIA terms used in this Indenture that are defined by the TIA, defined in the TIA by reference to another statute or defined by SEC Rule have the meanings assigned to them by such definitions.

13

which a Holder has the right to convert or exchange Securities of a series that are convertible or exchangeable, shall not be a Business Day (a “Legal Holiday”) at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Security other than a provision in any Security that specifically states that such provision shall apply in lieu hereof) payment need not be made at such Place of Payment on such date, and such Securities need not be converted or exchanged on such date but such payment may be made, and such Securities may be converted or exchanged, on the next succeeding day that is a Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or at the Stated Maturity or Maturity or on such last day for conversion or exchange, and no interest shall accrue on the amount payable on such date or at such time for the period from and after such Interest Payment Date, Stated Maturity, Maturity or last day for conversion or exchange, as the case may be, to the next succeeding Business Day.

For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of New York or a day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to be closed.

Section 1.17 No Security Interest Created.

Nothing in this Indenture or in any Securities, express or implied, shall be construed to constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect in any jurisdiction where property of the Company or its Subsidiaries is or may be located.

Securities not denominated in Dollars shall be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture.

Section 3.3 Execution, Authentication, Delivery and Dating.

Securities shall be executed on behalf of the Company by its Chairman of the Board, one of its Vice Chairmen, its President, its Treasurer, Assistant Treasurer, one of its Vice Presidents or other person authorized by resolution of the Board of Directors of the Company. The signature of any of these officers on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities, executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officers’ Certificate or supplemental indenture or indentures with respect to such Securities referred to in Section 301 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be provided with, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon,

(1) an Opinion of Counsel to the effect that:

(a) the form or forms and terms of such Securities have been established in conformity with the provisions of this Indenture;

(b) all conditions precedent to the authentication and delivery of such Securities have been complied with and that such Securities, when completed by appropriate insertions, executed under the Company’s corporate seal and attested by duly authorized officers of the Company, delivered by duly authorized officers of the Company to the Trustee for authentication pursuant to this Indenture, and authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement thereof may be subject to or limited by bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar laws relating to or affecting creditors’ rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a

20

proceeding in equity or at law) and will entitle the Holders thereof to the benefits of this Indenture; such Opinion of Counsel need express no opinion as to the availability of equitable remedies;

(c) all laws and requirements in respect of the execution and delivery by the Company of such Securities have been complied with;

and, to the extent that this Indenture is required to be qualified under the Trust Indenture Act in connection with the issuance of such Securities, to the further effect that:

(d) this Indenture has been qualified under the Trust Indenture Act; and

(2) an Officers’ Certificate stating that all conditions precedent to the execution, authentication and delivery of such Securities have been complied with and that, to the best knowledge of the Persons executing such certificate, no event which is, or after notice or lapse of time would become, an Event of Default with respect to any of the Securities shall have occurred and be continuing.

The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such action may not lawfully be taken.

Each Registered Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for in Section 202 or Section 612 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual or facsimile signature of one of its authorized officers. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

Section 3.4 Temporary Securities.

Pending the preparation of definitive Securities, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form.

Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and

21

deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations of the same series and containing identical terms and provisions. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary global Security, until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.

Section 3.5 Registration, Transfer and Exchange.

With respect to the Registered Securities of each series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Registered Securities of such series and of transfers of the Registered Securities of such series.

Such Office or Agency shall be the “Security Registrar” or “Registrar” for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities. The Company shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities.

Upon surrender for registration of transfer of any Registered Security of any series at any Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions.

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

A global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, any global Security shall be exchangeable for definitive Securities only if (i) the Depository is at any time unwilling, unable or ineligible to continue as Depository and a successor depository is not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii) the Depositary ceases to be a clearing agency registered under the Exchange Act of 1934, (iii) the Company executes and delivers to the Trustee a Company Order to the effect that such global Security shall be so exchangeable or (iv)

an Event of Default has occurred and is continuing with respect to the Securities. If the beneficial owners of interests in a global Security are entitled to exchange such interests for definitive Securities as the result of an event described in clause (i), (ii), (iii) or (iv) of the preceding sentence, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such global Security shall be surrendered from time to time by the U.S. Depository or such other Depository as shall be specified in the Company Order with respect thereto, and in accordance with instructions given to the Trustee and the U.S. Depository or such other Depository, as the case may be (which instructions shall be in writing but need not be contained in or accompanied by an Officers’ Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered global Security, a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such global Security to be exchanged; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date. Promptly following any such exchange in part, such global Security shall be returned by the Trustee to such Depository or the U.S. Depository, as the case may be, or such other Depository or U.S. Depository referred to above in accordance with the instructions of the Company referred to above. If a Registered portion of a global Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global Security shall be payable in accordance with the provisions of this Indenture.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid and legally binding obligations of the Company evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange.

Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Security Registrar for such Security) be duly endorsed, signature guaranteed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such Security duly executed by the Holder thereof, signature guaranteed, or his attorney duly authorized in writing.

23

No service charge shall be made for any registration of transfer or exchange, or redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Sections 304, 306 and 1107 not involving any transfer.

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of selection of Securities of like tenor and the same series under Section 1103 for redemption and ending at the close of business on the day of such selection, (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except in the case of any Security to be redeemed in part, the portion thereof not to be redeemed; or (iii) to issue, register the transfer of or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security is surrendered to the Trustee, subject to the provisions of this Section 306, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding.

If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security, and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or to a Responsible Officer of the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon the Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding.

Notwithstanding the foregoing provisions of this Section 306, in case any mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute a separate obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series duly issued hereunder.

The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, shall be exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.7 Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved.

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest.

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on such Registered Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Person entitled to such Defaulted Interest as in this clause provided. Thereupon, the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such Registered Security (or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Security

25

may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such payment shall be deemed practicable by the Trustee.

Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular series pursuant to the provisions of this Indenture, at the option of the Company, interest on Registered Securities that bear interest may be paid by wire transfer in immediately available funds if the holder of the Registered Security has provided to the Company and the Trustee wire instructions at least five business days prior to the applicable payment date or by check mailed to the address of that holder as it appears on the books of the Securities Registrar if that holder has not provided wire instructions; provided that the final distribution in respect of any Security will be made only upon presentation and surrender of such certificated debenture at the applicable Corporate Trust Office of the Trustee.

Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

In the case of any Registered Security of any series that is convertible, which Registered Security is converted after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than any Registered Security with respect to which the Stated Maturity is prior to such Interest Payment Date), interest with respect to which the Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Registered Security (or one or more predecessor Registered Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Registered Security which is converted, interest with respect to which the Stated Maturity is after the date of conversion of such Registered Security shall not be payable.

Section 3.8 Persons Deemed Owners.

Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Registered Security is registered in the Security Register as the owner of such Registered Security for the purpose of receiving payment of principal of, any premium and (subject to Section 305 and Section 307) interest on and any Additional Amounts with respect to such Registered Security and for all other purposes whatsoever, whether or not any payment with respect to such Registered Security shall be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary.

No Holder of any beneficial interest in any global Security held on its behalf by a Depository shall have any rights under this Indenture with respect to such global Security, and such Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the owner of such global Security for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Section 3.9 Cancellation.

All Securities surrendered for payment, redemption, registration of transfer, exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities, as well as Securities surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by or pursuant to this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures.

Section 3.10 Computation of Interest.

Except as otherwise provided in or pursuant to this Indenture, or in any Security, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 3.11 CUSIP Numbers.

The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE FOUR

Section 4.1 Satisfaction and Discharge.

Upon the direction of the Company by a Company Order, this Indenture shall cease to be of further effect with respect to any series of Securities specified in such Company Order and the Trustee, on receipt of a Company Order, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series, when

(1) either

(a) all Securities of such series theretofore authenticated and delivered and have been accepted by the Trustee for cancellation (other than (i) Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, and (ii) Securities of such series for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003); or

(i) have become due and payable, or

27

(ii) will become due and payable at their Stated Maturity within one year, or

(iii) if redeemable at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose, money in the Currency in which such Securities are payable in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, including the principal of, any premium and interest on, and any Additional Amounts with respect to such Securities, to the date of such deposit (in the case of Securities which have become due and payable) or to the Maturity thereof, as the case may be;

(2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Outstanding Securities of such series; and

(3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with.

In the event there are Securities of two or more series hereunder, the Trustee shall be required to execute an instrument acknowledging satisfaction and discharge of this Indenture only if requested to do so with respect to Securities of such series as to which it is Trustee and if the other conditions thereto are met.

Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of Securities, the obligations of the Company to the Trustee under Section 607 and, if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations of the Company and the Trustee with respect to the Securities of such series under Section 305, Section 306, Section 403, Section 1002 and Section 1003, with respect to the payment of Additional Amounts, if any, with respect to such Securities as contemplated by Section 1004 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 401(1)(b), and with respect to any rights to convert or exchange such Securities into Common Stock or other securities, cash or other property shall survive such satisfaction and discharge.

Section 4.2 Defeasance and Covenant Defeasance.

(1) Unless pursuant to Section 301, either or both of (i) defeasance of the Securities of or within a series under clause (2) of this Section 402 shall not be applicable with respect to the Securities of such series or (ii) covenant defeasance of the Securities of or within a series under clause (3) of this Section 402 shall not be applicable with respect to the Securities of such series, then such provisions, together with the other provisions of this Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities, and the Company may at its option by Board Resolution, at any time, with respect to such Securities, elect to have Section 402(2) or Section 402(3) be applied to such Outstanding Securities upon compliance with the conditions set forth below in this Section 402.

28

(2) Upon the Company’s exercise of the above option applicable to this Section 402(2) with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by such Outstanding Securities, which shall thereafter be deemed to be “Outstanding” only for the purposes of clause (6) of this Section 402 and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities to receive, solely from the trust fund described in clause (4) of this Section 402 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities when such payments are due, and any rights of such Holder to convert or exchange such Securities into Common Stock or other securities, cash or other property, (ii) the obligations of the Company and the Trustee with respect to such Securities under Section 305, Section 306, Section 1002 and Section 1003 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1004 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 402(4)(a) below), and with respect to any rights to convert or exchange such Securities into Common Stock or other securities, cash or other property, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 402. The Company may exercise its option under this Section 402(2) notwithstanding the prior exercise of its option under clause (3) of this Section 402 with respect to such Securities.

(3) Upon the Company’s exercise of the above option applicable to this Section 402(3) with respect to any Securities of or within a series, the Company shall be released from, to the extent specified pursuant to Section 301, any covenant applicable to such Securities, with respect to such Outstanding Securities on and after the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities, the Company may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any covenant or by reason of reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a default or an Event of Default under Section 501(4) insofar as it relates to, to the extent specified pursuant to Section 301, any covenant applicable to such Security, or Section 501(7) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

29

(b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Company is a party or by which it is bound.

(c) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities shall have occurred and be continuing on the date of such deposit and, with respect to defeasance only, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(ii) since the date of execution of this Indenture, there has been a change in the applicable Federal income tax law,

in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

(a) In the case of an election under clause (3) of this Section 402, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

30

(b) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, after the 91st day after the date of establishment of such trust, all money and Government Obligations (or other property as may be provided pursuant to Section 301) (including the proceeds thereof) deposited or caused to be deposited with the Trustee (or other qualifying trustee) pursuant to this clause (4) to be held in trust will not be subject to any case or proceeding (whether voluntary or involuntary) in respect of the Company under any Federal or State bankruptcy, insolvency, reorganization or other similar law, or any decree or order for relief in respect of the Company issued in connection therewith.

(6) Unless otherwise specified in or pursuant to this Indenture or any Security, if, after a deposit referred to in Section 402(4)(a) has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to Section 402(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the Foreign Currency in which the deposit pursuant to Section 402(4)(a) has been made, the indebtedness represented by such Security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any), and interest, if any, on, and Additional Amounts, if any, with respect to, such Security as the same becomes due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on (x) in the case of payments made pursuant to clause (a) above, the applicable market exchange rate for such Currency in effect on the second Business Day prior to each payment date, or (y) with respect to a Conversion Event, the applicable market exchange rate for such Foreign Currency in effect (as nearly as feasible) at the time of the Conversion Event.

31

The Company shall pay and indemnify the Trustee against any tax, fee or other charge, imposed on or assessed against the Government Obligations deposited pursuant to this Section 402 or the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities.

Anything in this Section 402 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4) of this Section 402 which, in the opinion of a nationally recognized independent registered public accounting firm expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with this Section 402.

Section 5.2 Acceleration of Maturity; Rescission and Annulment.

If an Event of Default with respect to Securities of any series at the time Outstanding (other than an Event of Default specified in clause (5) or (6) of Section 501) occurs and is continuing, then the Trustee may, and at the direction of the Holders of not less than 25% in principal amount of the Outstanding Securities of such series shall declare the principal of all the Securities of such series, or such lesser amount as may be provided for in the Securities of such series, to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any declaration the principal or such lesser amount shall become immediately due and payable. If an Event of Default specified in clause (5) or (6) of Section 501 above occurs, all unpaid principal of and accrued interest on the Outstanding Securities of that series (or such lesser amount as may be provided for in the Securities of such series) shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of any Security of such series.

At any time after a declaration of acceleration or automatic acceleration with respect to the Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereafter in this Article provided, the Holders of not less than a majority in principal amount of the Outstanding Securities of such series, by written notice to the Company and the Trustee, may rescind and annul the declaration and its consequences if:

(1) the Company has paid or deposited with the Trustee a sum of money sufficient to pay (i) all overdue installments of interest on all Securities of such series and any Additional Amounts payable with respect thereto, (ii) the principal of and any premium on any Securities of the series which have become due otherwise than by the declaration of acceleration and interest thereon and any Additional Amounts with respect thereto at the rate or rates borne by or provided in such Securities, (iii) interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and (iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(2) all Events of Default with respect to Securities of such series, other than the non-payment of the principal of, any premium and interest on, and any additional amounts with respect to Securities of such series which shall have become due solely by the acceleration, shall have been cured or waived as provided in Section 513.

Section 5.3 Collection of Indebtedness and Suits for Enforcement by Trustee.

The Company covenants that if

(1) default is made in the payment of any installment of interest on any Security, or any Additional Amounts payable with respect thereto, when such interest or Additional Amounts shall have become due and payable and such default continues for a period of 60 days, or

(2) default is made in the payment of any principal of or premium, if any, on, or any Additional Amounts payable in respect of any principal of or premium, if any, on any Security at its Maturity;

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount of money then due and payable with respect to such Securities, with interest upon the overdue principal, any premium and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest

34

and Additional Amounts at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount of money as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee under Section 607.

If the Company fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may and at the direction of the Holders of not less than 25% in principal amount of the Outstanding Securities of such series shall, so long as such Holders shall have provided the Trustee with such indemnity as it shall require, proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the exercise of any power granted herein or therein, or to enforce any other proper remedy.

Section 5.4 Trustee May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(1) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such series, of the principal and any premium, interest and Additional Amounts owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents or counsel) and of the Holders of Securities allowed in such judicial proceeding, and

(2) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Securities to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Securities, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 607.

35

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security in any such proceeding.

Section 5.5 Trustee May Enforce Claims without Possession of Securities.

All rights of action and claims under this Indenture or any of the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery or judgment, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, shall be for the ratable benefit of each and every Holder of a Security in respect of which such judgment has been recovered.

Section 5.6 Application of Money Collected.

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, or any premium, interest or Additional Amounts, upon presentation of the Securities, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

THIRD: The balance, if any, to the Company.

Section 5.7 Limitations on Suits.

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of such series;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Security to affect, disturb or prejudice the rights of any other such Holders or Holders of Securities of any other series, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders.

Section 5.8 Unconditional Right of Holders to Receive Principal and any Premium, Interest and Additional Amounts.

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of, any premium and (subject to Section 305 and Section 307) interest on, and any Additional Amounts with respect to such Security, on the respective Stated Maturity or Maturities therefor specified in such Security (or, in the case of redemption, on the Redemption Date or, in the case of repayment at the option of such Holder if provided in or pursuant to this Indenture, on the date such repayment is due) and to institute suit for the enforcement of any such payment, and such right shall not be impaired without the consent of such Holder.

The assertion or employment of any right or remedy hereunder, or otherwise, shall not, to the extent permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and

37

remedy given by this Article or by law to the Trustee or to any Holder of a Security may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such Holder, as the case may be.

Section 5.12 Control by Holders of Securities.

(2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 5.14 Waiver of Stay or Extension Laws.

The Company covenants that (to the extent that it may lawfully do so) it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company expressly waives (to the extent that it may lawfully do so) all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 6.6 Money Held in Trust.

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company.

Section 6.7 Compensation and Reimbursement.

The Company agrees:

(1) to pay to the Trustee from time to time such compensation as shall be agreed upon from time to time in writing between the Company and the Trustee for all services rendered by the Trustee hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture arising out of or in connection with the acceptance or administration of the trust or trusts hereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be caused by the Trustee’s own negligence or willful misconduct; and

(3) to fully indemnify each of the Trustee and any predecessor Trustee and its agents, officers, directors and employees for, and to hold them harmless against, any loss, liability,

42

damage, claim or expense (including reasonable legal fees and expenses), including taxes (other than taxes based on the income of the Trustee), incurred without negligence or willful misconduct on their part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the reasonable costs and expenses of defending themselves against any claim or liability (whether asserted by the Company, a Holder of Securities, or any other Person) in connection with the exercise or performance of any of their powers or duties hereunder.

As security for the performance of the payment obligations of the Company under this Section, the Trustee shall have a lien prior to the Securities of any series upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of, and premium or interest on or any Additional Amounts with respect to any Securities. Such lien shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after a Default or Event of Default specified in Section 501(5) and 501(6) hereof occurs, the expenses and the compensation for the services (including the fees and expense of its agents and counsel) are intended to constitute expense of administration under U.S. Code, Title 11 or any other similar foreign, federal or state law for the relief of debtors.

To the extent permitted by law any compensation or expense incurred by the Trustee after a default specified in or pursuant to Section 501 is intended to constitute an expense of administration under any then applicable bankruptcy or insolvency law. “Trustee” for purposes of this Section 607 shall include any predecessor Trustee but the negligence or willful misconduct of any Trustee shall not affect the rights of any other Trustee under this Section 607.

Notwithstanding any other provision of this Indenture to the contrary, in no event shall the Trustee be liable for special, indirect or consequential damages of any kind whatsoever (including but not limited to lost profits) even if the Trustee had been advised of the likelihood of such loss or damage and regardless of the form of action.

The provisions of this Section 607 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee and shall apply with equal force and effect to the Trustee in its capacity as Authenticating Agent, Paying Agent or Security Registrar.

43

(3) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and the Company.

(5) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by or pursuant to a Company Order, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of such series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 610.

Any Corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Corporation succeeding to all or substantially all of the corporate trust business of the Trustee by sale or otherwise, shall be the successor of the Trustee hereunder, provided such corporation shall otherwise be qualified under this Article VI without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated but not delivered by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 6.12 Appointment of Authenticating Agent.

The Trustee may appoint one or more Authenticating Agents acceptable to the Company with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of that or those series issued upon original issue, exchange, registration of transfer, partial redemption or partial repayment or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the

46

Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

Each Authenticating Agent must be acceptable to the Company and, except as provided in or pursuant to this Indenture, shall at all times be a Corporation that would be permitted by the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act, is authorized under applicable law and by its charter to act as an Authenticating Agent and has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section.

Any Corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, provided such Corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the Security Register. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Company agrees to pay each Authenticating Agent from time to time reasonable compensation for its services under this Section.

The provisions of Section 303, Section 601, Section 604 and Section 605 shall be applicable to each Authenticating Agent.

If an Authenticating Agent is appointed with respect to one or more series of Securities pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication in substantially the following form:

This is one of the Certificates described in the within-mentioned Indenture.

Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

Except as otherwise provided in or pursuant to this Indenture or the Securities of the applicable series, if the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which a payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium, if any, or interest on the Securities of such series shall be made to Holders of Securities of such series who are United States Aliens (as demonstrated by delivery of appropriate tax forms) without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of such series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities, and the Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished pursuant to this Section.

Section 10.5 Corporate Existence.

Subject to Article Eight, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and its rights (charter and statutory) and franchises; provided, however, that the foregoing shall not obligate the Company to preserve any such right or franchise if the Company shall determine that the preservation thereof is no longer desirable in the conduct of its business.

Section 10.6 Waiver of Certain Covenants.

The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 1003 and 1005 with respect to the Securities of any series if before the time for such compliance the Holders of at least a 66-2/3% majority in principal amount of the Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

Section 10.7 Company Statement as to Compliance; Notice of Certain Defaults.

(1) If any Securities are Outstanding under this Indenture, the Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, a written statement (which need not be contained in or accompanied by an Officers’ Certificate) signed by the principal executive officer, the principal financial officer, the principal accounting officer or other officer authorized by the Board of Directors of the Company, stating that

(a) a review of the activities of the Company during such year and of its performance under this Indenture has been made under his or her supervision, and

(b) to the best of his or her knowledge, based on such review, (a) the Company has complied with all the conditions and covenants imposed on it under this Indenture throughout such year, or, if there has been a default in the fulfillment of any such condition or covenant, specifying each such default known to him or her and the nature and status thereof, and (b) no event has occurred and is continuing which is, or after notice or lapse of time or both would become, an Event of Default, or, if such an event has occurred and is continuing, specifying each such event known to him or her and the nature and status thereof.

(2) The Company shall deliver to the Trustee, within 10 days after the occurrence thereof, written notice of any Event of Default or any event which after notice or lapse of time or both would become an Event of Default pursuant to clause (5) of Section 501.

(3) The Trustee shall have no duty to monitor the Company’s compliance with the covenants contained in this Indenture to other than if the Trustee receives a written notice described in Section 1007(2).

Section 10.8 Calculation of Original Issue Discount.

The Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time.

REDEMPTION OF SECURITIES

Section 11.1 Applicability of Article.

Redemption of Securities of any series at the option of the Company as permitted or required by the terms of such Securities shall be made in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article.

Section 11.2 Election to Redeem; Notice to Trustee.

The election of the Company to optionally redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Company of (a) less than all of the Securities of any series or (b) all of the Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed.

Section 11.3 Selection by Trustee of Securities to be Redeemed.

If less than all of the Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions of the principal amount of Registered Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Registered Security of such series not redeemed to less than the minimum denomination for a Security of such series established herein or pursuant hereto.

The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities which has been or is to be redeemed.

Unless otherwise specified in or pursuant to this Indenture or the Securities of any series, if any Security selected for partial redemption is converted into or exchanged for Common Stock or other securities, cash or other property in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection.

Section 11.4 Notice of Redemption.

Notice of redemption shall be given in the manner provided in Section 106, not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof.

58

Any notice that is mailed to the Holder of any Registered Securities in the manner herein provided shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice.

All notices of redemption shall state:

(1) the Redemption Date,

(2) the Redemption Price,

(3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed,

(4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

(5) that, on the Redemption Date, the Redemption Price shall become due and payable upon each such Security or portion thereof to be redeemed, and, if applicable, that interest thereon shall cease to accrue on and after said date,

(6) the place or places where such Securities are to be surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts pertaining thereto,

(7) that the redemption is for a sinking fund, if such is the case,

(8) in the case of Securities of any series that are convertible or exchangeable into Common Stock or other securities, cash or other property, the conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities of such series to be redeemed will commence or terminate and the place or places where such Securities may be surrendered for conversion or exchange, and

(9) the CUSIP number (or any other numbers used by a Depository to identify such Securities).

A notice of redemption published as contemplated by Section 106 need not identify particular Registered Securities to be redeemed.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company.

Section 11.5 Deposit of Redemption Price.

At or prior to 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit, with respect to the Securities of any series called for redemption pursuant to Section 1104, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 or in the Securities of such series) any accrued interest on and Additional Amounts with respect thereto, all such Securities or portions thereof which are to be redeemed on that date.

59

Section 11.6 Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest and Additional Amounts to the Redemption Date; provided, however, that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 307.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security.

Section 11.7 Securities Redeemed in Part.

Any Registered Security which is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same series, containing identical terms and provisions, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered.

Section 11.8 Repurchases on the Open Market.

The Company or any Affiliate of the Company may at any time or from time to time repurchase any of the Securities in the open market or otherwise. Such Securities may, at the option of the Company or the relevant Affiliate of the Company, be held, resold or surrendered to the Trustee for cancellation.

ARTICLE TWELVE

SINKING FUNDS

Section 12.1 Applicability of Article.

The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture or any Security of such series issued pursuant to this Indenture.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of such series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series and this Indenture.

Section 12.2 Satisfaction of Sinking Fund Payments with Securities.

The Company may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver Outstanding Securities of such series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company), and (2) apply as a credit Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to this Section 1202, the principal amount of Securities of such series to be redeemed in order to satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee need not call Securities of such series for redemption, except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the request of the Company from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that series purchased by the Company having an unpaid principal amount equal to the cash payment requested to be released to the Company.

Section 12.3 Redemption of Securities for Sinking Fund.

Not less than 75 days prior to each sinking fund payment date for any series of Securities, the Company shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 1202, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less than 60 days before each

61

such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 1106 and Section 1107.

ARTICLE THIRTEEN

REPAYMENT AT THE OPTION OF HOLDERS

Section 13.1 Applicability of Article.

Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 309, shall not operate as a payment, redemption or satisfaction of the Indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 1301, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers.

ARTICLE FOURTEEN

SECURITIES IN FOREIGN CURRENCIES

Section 14.1 Applicability of Article.

Whenever this Indenture provides for (i) any action by, or the determination of any of the rights of, Holders of Securities of any series in which not all of such Securities are denominated in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any provision to the contrary pursuant to this Indenture or the Securities of any particular series, any amount in respect of any Security denominated in a Foreign Currency shall be treated for any such action or distribution as that amount of Dollars that could be obtained for such amount on such reasonable basis of exchange and as of the record date with respect to Registered Securities of such series (if any) for such action, determination of rights or distribution (or, if there shall be no applicable record date, such other date reasonably proximate to the date of such action, determination of rights or distribution) as the Company may specify in a written notice to the Trustee or, in the absence of such written notice, as the Trustee may determine.

Exhibit 5.1

October 26, 2007

Board of Directors

RadiSys Corporation

5445 NE Dawson Creek Rd.

Hillsboro, OR 97124

We have been requested by RadiSys Corporation, an Oregon corporation (the Company”), to deliver this opinion in connection with the filing by the Company of a Registration Statement on Form S-3 (the “Registration Statement”) under the Securities Act of 1933. The Company has provided us with a prospectus (the “Prospectus”), which forms part of the Registration Statement. The Prospectus provides that it will be supplemented in the future by one or more prospectus supplements (each, a “Prospectus Supplement”). The Registration Statement, including the Prospectus as supplemented from time to time by one or more Prospectus Supplements, will provide for the registration by the Company of:

(i) shares of common stock of the Company (the “Common Stock”);

(ii) shares of preferred stock of the Company (the “Preferred Stock”);

(iii) debt securities, warrants and units comprised of one or more debt or equity securities, in any combination (the “Other Securities”).

The Common Stock and the Preferred Stock are collectively referred to herein as the “Shares.” The Shares are being registered for offering and sale from time to time pursuant to Rule 415 under the Securities Act. The maximum aggregate public offering price of the Shares and the Other Securities is $150,000,000.

We have reviewed the corporate action of the Company in connection with this matter and have examined the documents, corporate records and other instruments we deemed necessary for the purpose of this opinion.

In rendering this opinion, we have assumed the genuineness and authenticity of all signatures on original documents; the authenticity of all documents submitted to us as originals; the conformity to originals of all documents submitted to us as copies; the accuracy, completeness and authenticity of certificates of public officials; and the due authorization, execution and delivery of all documents where authorization, execution and delivery are prerequisites to the effectiveness of such documents. With respect to our opinion as to the Common Stock, we have assumed that, at the time of issuance and sale, a sufficient number of shares of Common Stock will be authorized and available for issuance. With respect to our opinion as to the Preferred Stock, we have assumed that, at the time of issuance and sale, a sufficient number of shares of Preferred Stock will be authorized, designated and available for issuance.

Our opinion herein is expressed solely with respect to the federal laws of the United States and the Oregon Business Corporation Act. Our opinion is based on these laws as in effect on the date hereof. We express no opinion as to whether the laws of any jurisdiction are applicable to the subject matter hereof.

On the basis of the foregoing and in reliance thereon, and subject to the qualifications herein stated, we are of the opinion that:

(1) With respect to the Common Stock offered under the Registration Statement, provided that (i) the issuance of the Common Stock has been duly authorized by all necessary corporate action on the part of the Company; and (ii) the shares of Common Stock have been delivered to the purchasers thereof against payment therefor, the Common Stock, when issued and sold as contemplated in the Registration Statement, the Prospectus and the related Prospectus Supplement(s) and in accordance with any applicable duly authorized, executed and delivered purchase, underwriting or similar agreement, or upon conversion of any convertible Preferred Stock, or convertible debt securities in accordance with their terms, or upon exercise of any warrants in accordance with their terms, will be duly authorized, validly issued, fully paid and nonassessable;

The Registration Statement relates to the following securities: (i) unsecured debt securities of the Company, in one or more series (the “Debt Securities”), which may be issued under a base indenture (the “Indenture”) between the Company and a trustee designated therein (a “Trustee”), as supplemented by a supplemental indenture, (ii) preferred stock of the Company (par value $0.01 per share), in one or more series (the “Preferred Stock”), (iii) common stock of the Company, without par value (the “Common Stock”), (iv) warrants (the “Warrants”) to purchase Debt Securities, Preferred Stock or Common Stock of the Company, which may be issued pursuant to one or more warrant agreements proposed to be entered into between the Company and a warrant agent or agents to be named, to be sold separately or with Debt Securities, Preferred Stock, Common Stock or other securities of the Company, (v) fractional shares of the Company’s Preferred Stock represented by depositary shares (the “Depositary Shares”), evidenced by depositary receipts (the “Depositary Receipts”), which may be issued pursuant to one or more deposit agreements proposed to be entered into between the Company and a bank or trust company to be named (each, a “Deposit Agreement”), and (vi) units of securities of the Company (the “Units”) consisting of one or more Warrants, Debt Securities, debt obligations of third parties, including United States treasury obligations, Common Stock, Preferred Stock, Depositary Shares, or any combination thereof (such Debt Securities, Warrants, Depositary Shares and Units are collectively referred to herein as the “Offered Securities”), all of which may be issued from time to time on a delayed or continuous basis pursuant to Rule 415 of the General Rules and Regulations promulgated under the Securities Act for an aggregate offering price of up to $150,000,000.00. We have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Second Restated Articles of Incorporation and the Restated Bylaws of the Company, each as amended to the date hereof (the “Charter Documents”), (ii) resolutions adopted by the board of directors of the Company (the “Resolutions”), (iii) the form of the Indenture included as an exhibit to the Registration Statement, (iv) the form of the Registration Statement and (v) such other certificates, statutes and other instruments and documents as we considered appropriate for purposes of the opinions hereafter expressed.
	Baker & McKenzie LLP is a member of Baker & McKenzie International, a Swiss Verein.

As to any facts material to our opinion, we have made no independent investigation of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Company.

In rendering the opinions set forth below, we have assumed that (i) all information contained in all documents reviewed by us is true and correct, (ii) all signatures on all documents examined by us are genuine, (iii) all documents submitted to us as originals are authentic and all documents submitted to us as copies conform to the originals of those documents, (iv) each natural person signing any document reviewed by us had the legal capacity to do so and (v) any document under which, if applicable, the Offered Securities may be issued have been or will have been duly authorized, executed and delivered (other than on behalf of the Company) by persons with authority to sign in such capacity.

Based on the foregoing, we are of the opinion that:

1. Debt Securities. When the Registration Statement has become effective under the Securities Act, the Indenture relating to the Debt Securities, as supplemented by a supplemental indenture, has been duly authorized, executed and delivered by each of the parties thereto in accordance with applicable law and substantially in the form filed as an exhibit to the Registration Statement, the terms of the Debt Securities and of their issuance and sale have been duly established in conformity with the Indenture, as supplemented by a supplemental indenture, and the Debt Securities have been duly executed and authenticated in accordance with the Indenture, as supplemented by a supplemental indenture, and issued and sold as contemplated in the Registration Statement and all of the foregoing actions are taken pursuant to authority granted in the Resolutions and so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, the Debt Securities will constitute valid and legally binding obligations of the Company.

2. Warrants. When the Registration Statement has become effective under the Securities Act, the warrant agreement relating to the Warrants (the “Warrant Agreement”) has been duly authorized, executed and delivered in accordance with applicable law and substantially in the form filed as an exhibit to the Registration statement, the terms of the Warrants and of their issuance and sale have been duly established in accordance with applicable law and in conformity with the Warrant Agreement and the Warrants have been duly executed and countersigned in accordance with applicable law and the Warrant Agreement and issued and sold as contemplated in the Registration Statement and the Warrant Agreement, and all of the foregoing actions are taken pursuant to the authority granted in the Resolutions and so as not to violate any applicable law or result in a default

Page 2

under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, the Warrants will constitute valid and legally binding obligations of the Company.

3. Depositary Shares. When the Registration Statement has become effective under the Securities Act, the Deposit Agreement to be entered into between the Company and a bank or trust company selected by the Company to act as depositary thereunder (the “Depositary”) has been duly authorized, executed and delivered in accordance with applicable law and substantially in the form filed as an exhibit to the Registration Statement, the terms of the Depositary Shares and of their issuance and sale have been duly established in conformity with applicable law and the Deposit Agreement, the Preferred Stock represented by the Depositary Shares has been duly authorized, validly issued, fully paid and non-assessable in accordance with applicable law and delivered to the Depositary and the Depositary Receipts evidencing the Depositary Shares have been executed and countersigned in accordance with applicable law and the Deposit Agreement and issued against deposit of the Preferred Stock and issued and sold as contemplated by the Registration Statement and the Deposit Agreement, and all of the foregoing actions are taken pursuant to the authority granted in the Resolutions and so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company, the Depositary Receipts evidencing the Depositary Shares will be validly issued and will entitle the holders thereof to the rights specified in the Depositary Shares and the Deposit Agreement.

The foregoing opinions are qualified to the extent that the enforceability of any document, instrument or Offered Security may be limited by or subject to (i) bankruptcy, insolvency, fraudulent transfer or conveyance, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally, and general equitable or public policy principles, and (ii) with respect to any Debt Securities denominated in a currency other than United States dollars, the requirement that a claim (or a foreign currency judgment in respect of such a claim) with respect to such Debt Securities be converted to United States dollars at a rate of exchange prevailing on a date determined pursuant to applicable law or governmental authority.

The foregoing opinions are limited in all respects to the corporate laws of the State of New York and the federal laws of United States of America, in each case, that, in our experience, are normally applicable to transactions of the type contemplated by the Registration Statement and, to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws, and we do not express any opinions as to the laws of any other jurisdiction. With respect to all matters of Oregon law, we note that you are being provided with the opinion, dated on or about the date

Page 3

hereof, of Stoel Rives LLP, Oregon counsel to the Company. For purposes of our opinion, we have assumed that the Company has been duly incorporated and is a validly existing corporation under the laws of Oregon and that, where applicable, the issuance or delivery by the Company of any shares of Common Stock or Preferred Stock upon exercise or otherwise pursuant to the terms of any Offered Securities will be duly authorized, executed, authenticated, issued and delivered by the Company in accordance with Oregon law and pursuant to the authority granted in the Resolutions and that the authority granted in the Resolutions will remain in effect at all relevant times. The Offered Securities may be issued from time to time on a delayed or continuous basis, and this opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof, which laws are subject to change with possible retroactive effect and to the facts as they presently exist. We are expressing no opinion as to any obligations that parties other than the Company may have under or in respect of the Offered Securities or as to the effect that their performance of such obligations may have upon any of the matters referred to above.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name under the caption “Legal Matters” in the prospectus forming a part of the Registration Statement. In giving this consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act and the rules and regulations of the SEC issued thereunder.

Very truly yours,

(a) Included in income (loss) before taxes and discontinued operations was a gain (loss) on repurchase of convertible subordinated notes of ($50) thousand, ($387) thousand, $825 thousand and $3.0 million for years ended December 31, 2005, 2004, 2003 and 2002, respectively. The Company did not incur any gains or losses on early extinguishment of debt for the year ended December 31, 2006 or for the six months ended June 30, 2007.

(b) Amortization of the discount on the Company’s outstanding convertible subordinated notes is included in Interest expense.

(c) In 2005, the Company’s Board of Directors renewed the authorization to repurchase all remaining convertible subordinated notes in the open market if and when appropriate opportunities present themselves. If the Company elects to repurchase its convertible subordinated notes in the open market, interest expense from convertible subordinated notes will decrease.

(d) Management believes that 14% is a reasonable approximation of the interest factor on rentals. Building, office and other equipment rental fees that were included in restructuring charges were excluded from fixed charges.

(e) The earnings to fixed charges ratio was less than 1:1 due to the losses reported for the six months ended June 30, 2007 and for the years ended December 31, 2006 and 2002. To achieve an earnings to fixed charges ratio of 1:1, the Company would need to generate additional income of $15.4 million, $13.8 million and $4.5 million, respectively.
