NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 - Significant Accounting Policies

RadiSys Corporation (the “Company” or “RadiSys”) has adhered to the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2009 in preparing the accompanying interim consolidated financial statements. The preparation of these statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Additionally, the accompanying financial data as of September 30, 2010 and for the three and nine months ended September 30, 2010 and 2009 has been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2009.

The financial information included herein reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for interim periods.

Recent Accounting Pronouncements

In January 2010, the FASB issued Accounting Standard Update ("ASU") No. 2010-06, "Improving Disclosures about Fair Value Measurements"("ASU 2010-06"), which amended standards to require additional fair value disclosures. These amended standards require disclosures about inputs and valuation techniques used to measure fair value as well as disclosures about significant transfers, beginning in the first quarter of 2010. Additionally, these amended standards require presentation of disaggregated activity within the reconciliation for fair value measurements using significant unobservable inputs (Level 3), beginning in the first quarter of 2011. The Company adopted the applicable portion of the ASU 2010-06 during the three months ended March 31, 2010. The implementation of this portion of ASU 2010-06 did not have a material impact on the Company’s financial position, financial performance, or cash flows; however, it changed the way in which the Company discloses information regarding fair value measurements. The implementation of the remaining portions of this standard will not have a material impact on the Company’s financial position, financial performance, or cash flows; however, it will change the way in which the Company discloses information regarding fair value measurements.

Revenue Recognition

Multiple Element Arrangements

A significant portion of the Company's revenue relates to product sales for which revenue is recognized upon shipment, with limited judgment required related to product returns. The software content included in certain components of Advanced Telecommunications Computing Architecture ("ATCA") systems and Convedia Media Servers is considered to be more than incidental and these arrangements generally include multiple elements such as hardware and technical support services as well as software upgrades or enhancements on a when and if available basis. Arrangements that include multiple elements require significant management judgment to evaluate the effective terms of agreements and the Company's performance commitments and to determine the fair value of the various deliverables under the arrangement. During the first quarter of 2010 the Company elected early adoption of ASU No. 2009-13, “Multiple-Deliverable Revenue Arrangements—a consensus of the FASB Emerging Issues Task Force” ("ASU 2009-13") and ASU No. 2009-14, “Certain Arrangements That Include Software Elements,” (amendments to FASB ASC Topic 985, Software) (“ASU 2009-14”). Adoption of ASU 2009-13 and ASU 2009-14 allows the Company to meet separation criteria required for multiple element arrangements where it could not previously establish a fair value for one or more of the relevant deliverables. Previously, when the Company could not establish fair value for certain technical support agreements all revenue was deferred. These revenues were then recognized over the appropriate period, generally coinciding with an explicit or implied support period, or in some cases deferred until all elements of the arrangement had been delivered. Under ASU 2009-13, overall consideration is allocated among the separate units of accounting based on their relative fair value. This will result in the ability to recognize each unit of accounting upon delivery. Revenue for hardware, which includes software that is considered more than incidental, will be recognized upon delivery whereas technical support services will be recognized over the applicable service period.

ASU 2009-13 provides a fair value hierarchy in order to determine the appropriate relative fair value for each element of

7

an arrangement. When available, the Company uses vendor specific objective evidence (“VSOE”) to determine the estimated selling price. In the absence of VSOE or third-party evidence ("TPE") for a delivered element, the Company then uses an estimated selling price in order to determine fair value. Estimated selling prices represent the Company's best estimate of the price at which it would transact if the deliverables were sold on a standalone basis. For technical support services, the Company generally determines its selling price based on VSOE as supported by substantive renewal rates in the related service agreements. In certain instances where the Company has no service agreement or VSOE cannot be established, the Company then relies upon its estimated selling price for such deliverables as TPE is generally not available due to the unique company-specific terms surrounding such service agreements. In establishing an appropriate estimated selling price for these technical support agreements, the Company considered entity specific factors such as its historical and projected costs, historical and projected revenues, and profit objectives. The Company also considered market specific factors when establishing reasonable profit objectives.

The transition guidance provided within ASU 2009-13 is only allowed to be applied to new or substantially modified arrangements. No previously existing arrangements were modified during the quarter and therefore existing arrangements were not effected by ASU 2009-13. This guidance was applied to new revenue arrangements arising in the nine months ended September 30, 2010 where tangible products were bundled with technical support services.

Adoption of ASU 2009-13 and ASU 2009-14 has not materially affected the Company's consolidated financial statements for the three and nine months ended September 30, 2010.

Total short-term investments and ARS settlement right	$	—	$	—	$	62,154	$	62,154

^(A)  Balance includes $826,000 in money market mutual funds restricted by the Company’s investment bank as of December 31, 2009. All restricted amounts were held as collateral by the Company’s investment bank unless the bank permitted withdrawal of all or part of such amounts.

As of December 31, 2009, the Company held investments in auction rate securities (“ARS”), the majority of which represented interests in collateralized debt obligations supported by pools of government-backed student loans with S&P AAA or Moody's Aaa ratings at the time of purchase. During the first quarter of 2008, the Company's portfolio of ARS experienced multiple failed auctions as the amount of securities submitted for sale exceeded the amount of purchase orders. An auction failure, which is not a default in the underlying debt instrument, occurs when there are more sellers than buyers at a scheduled interest rate auction date and parties desiring to sell their auction rate securities are unable to do so. During the fourth quarter of 2008, the Company accepted a settlement offer from its investment bank, UBS AG, the parent company of the securities firm with which the Company holds its ARS, associated with the failed auctions. Under the terms of the offer, the Company had the right to require the bank to repurchase at par value its ARS investments at any time between June 30, 2010 and June 30, 2012. As the Company planned to require UBS to repurchase its ARS on June 30, 2010, these investments were classified as short-term investments at December 31, 2009. For its ARS settlement right, the Company elected the fair value option for financial assets and financial liabilities. Management elected the fair value option for the ARS settlement right in order to quantify its agreement with UBS, as it guarantees settlement at par value, which essentially offsets any impairment on its ARS.

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

8

The Company determined the fair value of its ARS settlement right based on the difference between the estimated fair value of the ARS and the par value of the ARS. This difference was then discounted based on the future date when the settlement right is expected to be exercised to account for the time value of money and to reflect the degree of credit risk associated with UBS. The discount rate used took into consideration the risk free rate as well as UBS's credit quality.

On June 30, 2010, the Company exercised its settlement right with UBS and as a result the investment bank repurchased the Company's remaining balance of ARS. On July 1, 2010, the transaction settled and the Company had no outstanding balances on its UBS line of credit nor any restricted money market mutual funds. The Company recorded net gains of $21,000 during the nine months ended September 30, 2010 resulting from the exercise of its settlement right. These gains are included in other income, net in the accompanying Consolidated Statement of Operations.

Note 3 — Fair Value of Financial Instruments

The Company measures at fair value certain financial assets and liabilities. GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1—Quoted prices for identical instruments in active markets;

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

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

The following table summarizes the fair value measurements as of September 30, 2010, for the Company's financial instruments, (in thousands):

Sales of auction rate securities	(62,175		)	—
Balance as of September 30, 2010	$	—		$	—

(A)

Refer to Note 2 - Investments for discussion of the inputs used in determining the appropriate fair values for the Company's ARS and ARS settlement right. Realized gains related to the Company's ARS, which totaled $7.9 million for the nine months ended September 30, 2010 are included in other income in the Company's Consolidated Statement of Operations. Unrealized gains on the Company’s ARS, which totaled $1.3 million and $4.1 million for the three and nine months ended September 30, 2009, respectively, are included in other income in the Company’s Consolidated Statement of Operations.

(B)

Valuation of the Company's ARS settlement right was performed using a present value approach on the difference between the estimated fair value and the par value of the ARS investments. Therefore, there was an inverse relationship between changes in the value of the Company's ARS investments and its settlement right. Realized losses related to the Company's ARS settlement right, which totaled $7.8 million for the nine months ended September 30, 2010, are included in other income in the Company's Consolidated Statement of Operations. Unrealized losses on the Company’s ARS settlement right, which totaled $1.2 million and $3.7 million, for the three and nine months ended September 30, 2009, respectively, are included in other income in the Company’s Consolidated Statement of Operations.

Note 4 — Accounts Receivable and Other Receivables

Accounts receivable consists of trade accounts receivable. Accounts receivable balances consisted of the following (in thousands):

	September 30, 2010			December 31, 2009
Accounts receivable, gross	$	44,602		$	45,580
Less: allowance for doubtful accounts	(955		)	(966		)
Accounts receivable, net	$	43,647		$	44,614

The Company did not utilize any of its provision for allowance for doubtful accounts during the three months ended September 30, 2010, while it utilized $11,000 during the nine months ended September 30, 2010. The Company recorded no additional provisions for allowance for doubtful accounts during the three and nine months ended September 30, 2010 and 2009.

As of September 30, 2010 and December 31, 2009, the balance in other receivables was $2.2 millionand $3.7 million, respectively. Other receivables consisted primarily of non-trade receivables including receivables for inventory sold to the Company's contract manufacturing partners. There is no revenue recorded associated with non-trade receivables.

Note 5 — Inventories

Inventories consisted of the following (in thousands):

Inventory deposit, net	$	5,497		$	2,126

^(A)  The Company is contractually obligated to reimburse one of its contract manufacturers for the cost of excess inventory, purchased based on the Company's forecasted demand, when there is no alternative use. The Company's inventory deposit represents a cash deposit paid to one of its contract manufacturers. The deposit is recorded net of adverse purchase commitment liabilities, and therefore the net balance of the deposit represents inventory the Company believes will be utilized. The deposit will be applied against future adverse purchase commitments owed to the Company's contract manufacturers or reduced based on the usage of inventory. See Note 10 - Commitments and Contingencies for additional information regarding the Company's adverse purchase commitment liability.

Consigned inventory is held at third-party locations, including the Company's contract manufacturing partners and customers. The Company retains title to the inventory until purchased by the third-party. Consigned inventory, consisting of raw materials and finished goods, was $3.1 millionand $3.0 million at September 30, 2010 and December 31, 2009, respectively.

During the three months ended September 30, 2010 and 2009, the Company recorded provisions for excess and obsolete inventory of $186,000 and $618,000, respectively. During the nine months ended September 30, 2010 and 2009, the Company recorded provisions for excess and obsolete inventory of $1.0 million and $2.6 million, respectively.

Note 6 — Business Combinations

Pactolus

On March 11, 2010, the Company acquired the assets of Pactolus Communications Software Company ("Pactolus"), a developer of next-generation IP communications solutions for converged time-division multiplexing/internet protocol ("TDM/IP") and session initiation protocol ("SIP") enabled voice over internet protocol ("VoIP") networks. The Company paid $3.5 million in cash on the closing date and assumed certain contractual liabilities of Pactolus. The purchase price was allocated to Pactolus' assets and liabilities based on their estimated fair value as follows:

Cash	$	115
Tangible assets	490
Liabilities assumed	(565		)
Developed technology	2,600
Customer related intangibles	700
Goodwill	160
Total	$	3,500

Developed technology will be amortized over a period of approximately five years and customer related intangibles will be amortized over approximately four years. Goodwill was calculated as the purchase price in excess of the fair values of Pactolus' assets and liabilities.

Pro forma results of operations have not been presented for this acquisition because its effect was not material to the Company.

Note 7 — Accrued Restructuring and Other Charges

Accrued restructuring, which is included in other accrued liabilities in the accompanying Consolidated Balance Sheets as of September 30, 2010 and December 31, 2009, consisted of the following (in thousands):

11

	September 30, 2010		December 31, 2009
First quarter 2009 restructuring charge	$	—	$	263
Second quarter 2009 restructuring charge	208		1,933
Fourth quarter 2009 restructuring charge	306		829
Total accrued restructuring charges	$	514	$	3,025

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

First Quarter 2009 Restructuring

During the first quarter of 2009, the Company initiated a restructuring plan that included the elimination of 29 positions. The restructuring was initiated in an effort to lower the Company's overall cost structure in accordance with operating plan targets. Total costs of the first quarter 2009 restructuring activities included accrued severance obligations, and healthcare benefits, which totaled $1.5 million. During the three months ended September 30, 2009, the Company incurred $4,000 in additional restructuring charges, which were comprised entirely of employee payroll related severance costs. During the nine months ended September 30, 2010, the Company recorded a net reversal of $85,000 of previously recorded expenses resulting primarily from the re-assignment of employees initially included in the restructuring plan. During the nine months ended September 30, 2009, the Company incurred a total of $1.5 million in restructuring charges, which were comprised almost entirely of employee payroll related severance costs. As of September 30, 2010, all activities associated with this restructuring were completed.

The following table summarizes the changes to the first quarter 2009 restructuring costs (in thousands):

Second Quarter 2009 Restructuring

During the second quarter of 2009, the Company initiated a restructuring plan that included the elimination of 115 positions and the relocation of eight employees as part of two strategic initiatives within manufacturing operations and engineering. As part of the initiative, the Company began a transition to a fully outsourced manufacturing model, which would transfer remaining manufacturing from its manufacturing plant in Hillsboro, Oregon to its manufacturing partners in Asia. The plan also included consolidating the Company's North American research and development ("R&D") positions and programs, and specifically transferring current projects from its design center in Boca Raton, Florida, to other existing R&D centers. To date, the Company has incurred total second quarter 2009 restructuring costs of $3.2 million which has consisted primarily of accrued severance obligations, healthcare benefits, relocation incentives and related payroll taxes as well as equipment moving costs.

During the three months ended September 30, 2010, the Company recorded a net reversal of $42,000, which primarily consisted of a reversal of $65,000 in costs associated with employee severance, healthcare benefits, and associated payroll costs. This reversal was caused by changes in previously estimated costs associated with this restructuring plan. Partially offsetting these reversals were $23,000 in additional facilities related costs resulting from the transition to a fully outsourced manufacturing model. During the three months ended September 30, 2009, the Company incurred an additional $171,000 in costs consisting of equipment moving fees along with other facilities related charges.

During the nine months ended September 30, 2010, the Company incurred an additional $371,000 in expenses while it reversed $342,000 in previously estimated amounts associated with the second quarter of 2009 restructuring plan. The additional costs consisted of $219,000 in employee severance, healthcare benefits and associated payroll costs along with facilities related costs and legal fees of $152,000. Reversals consisted of $314,000 in previously estimated employee severance, healthcare benefits and associated payroll costs, primarily associated with retaining employees in new roles with the Company. In addition, the

12

Company reversed $28,000 in facilities related expenses. During the nine months ended September 30, 2009, the Company incurred $3.2 million in restructuring expenses, which consisted of accrued severance obligations, healthcare benefits, relocation incentives and related payroll taxes as well as facilities related charges. All activities associated with this restructuring plan are expected to be complete by the fourth quarter of 2010.

The following table summarizes the changes to the second quarter 2009 restructuring costs (in thousands):

	Employee Termination and Related Costs			Other			Total

Fourth Quarter 2009 Restructuring

During the fourth quarter of 2009, the Company initiated a restructuring plan that included the elimination of 22 positions at various locations throughout the company. The primary focus of this initiative was to align expenses with the Company's 2010 operating plan objectives, which included the need to continue focusing on lowered costs. To date, the Company has incurred total fourth quarter 2009 restructuring costs of $781,000, which consisted primarily of severance and related payroll costs as well as healthcare benefits.

During the three months ended September 30, 2010, the Company recorded a net reversal of $181,000 in costs primarily associated with employee severance, healthcare benefits, and associated payroll costs. Specifically, the Company reversed $192,000 in previously accrued amounts for employee severance, healthcare benefits, and associated payroll costs primarily related to changes in previously estimated expenses. In addition, a portion of these reversals relates to employees who will now be retained by the Company. These reversals were offset by additional expenses for legal fees and foreign currency adjustments, which collectively totaled $12,000. During the nine months ended September 30, 2010, the Company recorded a net reversal of $138,000 in previously accrued amounts associated with this restructuring plan. Specifically, the Company reversed previously accrued costs for employee severance, healthcare benefits and associated payroll costs in the amount of $231,000 primarily related to changes in previously estimated expenses. In addition, a portion of these reversals relates to employees who will now be retained by the Company. Offsetting these reversals were changes to previously estimated amounts for employee severance, healthcare benefits and associated payroll costs in the amount of $66,000 along with additional costs for legal fees and foreign currency adjustments collectively totaling $27,000. The Company expects all activities associated with this restructuring plan to be completed by the end of 2011.

The following table summarizes the changes to the fourth quarter 2009 restructuring costs (in thousands):

	Employee Termination and Related Costs
Balance accrued as of December 31, 2009	$	829

Note 8 — Short-Term Borrowings

Silicon Valley Bank

The Company has a secured revolving line of credit agreement with Silicon Valley Bank, which provides the Company with a two-year secured revolving credit facility of $30.0 million, which is subject to a borrowing base and secured by its accounts receivable. The term of the agreement goes through September 30, 2011. Borrowings under the agreement bear interest at the prime rate, which was 3.25% as of September 30, 2010, or LIBOR, which was 0.26% as of September 30, 2010, plus 1.25%, with either interest rate determined by the Company’s election. The Company is required to make interest payments monthly. The

13

Company is further required to pay a commitment fee equal to 0.08% of the $30.0 million maximum borrowing limit on an annual basis, and to pay quarterly in arrears an unused facility fee in an amount equal to 0.375% per year of the unused amount of the facility. In addition, the credit facility provides sub-facilities for letters of credit and foreign exchange contracts to be issued on the Company’s behalf.

The credit facility requires the Company to make and maintain certain financial covenants, representations, warranties and other agreements that are customary in credit agreements of this type, which are disclosed in the Company's annual report on Form 10-K for the year ended December 31, 2009. As of September 30, 2010, the Company was in compliance with all covenants associated with its line of credit agreement with Silicon Valley Bank.

As of September 30, 2010, and December 31, 2009, respectively, the Company had no outstanding balances on the line of credit or letters of credit issued on its behalf.

On November 2, 2010, the Company amended its line of credit agreement with Silicon Valley Bank to extend the term of the agreement and modify certain of its terms. See Note 16 – Subsequent Events for additional details of this amendment.

UBS

During the fourth quarter of 2008, the Company accepted a settlement offer from its investment bank, UBS, associated with failed auctions for its previously held ARS. Under the terms of the offer, the Company had the right to require the bank to repurchase at par value its ARS investments at any time between June 30, 2010 and June 30, 2012. Under the terms of the offer, UBS issued ARS settlement rights to the Company, which in addition to the terms discussed in Note 2 - Investments, also entitled the Company to receive no net cost loans from UBS, or its affiliates, for up to 75% of the market value of the Company's ARS.

On June 30, 2010, the Company exercised its settlement right with UBS, which resulted in the repurchase by UBS of the Company's remaining ARS investments. As of June 30, 2010, the exercise of the Company's settlement right with UBS had not fully settled and, therefore, the Company had an outstanding balance of $17.3 million on its line of credit with UBS. On July 1, 2010, upon complete settlement of the transaction to exercise its settlement right with UBS, the Company repaid its line of credit with UBS in full and has no further unused capacity or ability to borrow under this line of credit.

Note 9 - Convertible Debt

2013 Convertible Senior Notes

During February 2008, the Company offered and sold in a public offering pursuant to the shelf registration statement $55.0 million aggregate principal amount of 2.75% convertible senior notes due 2013 (the “2013 convertible senior notes”). Interest on the 2013 convertible senior notes is payable semi-annually, in arrears, on each August 15 and February 15, beginning on August 15, 2008, to the holders of record at the close of business on the preceding August 1 and February 1, respectively. The 2013 convertible senior notes mature on February 15, 2013. Holders of the 2013 convertible senior notes may convert their notes into a number of shares of the Company's common stock determined as set forth in the indenture governing the notes at their option on any day up to and including the business day prior to the maturity date. The 2013 convertible senior notes are initially convertible into 76.7448 shares of the Company's common stock per $1,000 principal amount of the notes (which is equivalent to a conversion price of approximately $13.03 per share), subject to adjustment upon the occurrence of certain events. Upon the occurrence of a fundamental change, holders of the 2013 convertible senior notes may require the Company to repurchase some or all of their notes for cash at a price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest, if any. In addition, if certain fundamental changes occur, the Company may be required in certain circumstances to increase the conversion rate for any 2013 convertible senior notes converted in connection with such fundamental changes by a specified number of shares of the Company's common stock. The 2013 convertible senior notes are the Company's general unsecured obligations and rank equal in right of payment to all of its existing and future senior indebtedness, and senior in right of payment to the Company's future subordinated debt. The Company's obligations under the 2013 convertible senior notes are not guaranteed by, and are effectively subordinated in right of payment to all existing and future obligations of its subsidiaries and are effectively subordinated in right of payment to its future secured indebtedness to the extent of the assets securing such debt.

In connection with the issuance of the 2013 convertible senior notes, the Company entered into a capped call transaction with a hedge counterparty. The capped call transaction is expected to reduce the potential dilution upon conversion of the 2013 convertible senior notes in the event that the market value per share of the Company's common stock, as measured under the terms of the capped call transaction, at the time of exercise is greater than the strike price of the capped call transaction of approximately $13.03. The strike price of the capped call transaction corresponds to the initial conversion price of the 2013 convertible senior notes and is subject to certain adjustments similar to those contained in the notes. The capped call transaction provides for net-share settlement in the event that the volume-weighted average price per share of the Company's common stock on the settlement date exceeds the strike price of approximately $13.03 per share. In such event, the hedge counterparty would deliver to the Company a number of shares equal to a formula determined by the quotient resulting from (a) the shares being settled times the difference

14

between the volume-weighted average price on the settlement date and the strike price of approximately $13.03 per share, divided by (b) the volume-weighted average price on the settlement date. If the volume-weighted average price on the settlement date equals or exceeds the cap price of $23.085 per share, the difference in (a) would be $23.085 minus $13.03, or $10.055. If the market value per share of the Company's common stock exceeds the cap price of the capped call transaction of $23.085, as measured under the terms of the capped call transaction, the dilution mitigation under the capped call transaction will be limited, which means that there would be dilution to the extent that the then market value per share of the Company's common stock exceeds the cap price of the capped call transaction. Although the capped call transaction covers approximately 4.2 million shares, in order to facilitate an orderly settlement process, the shares are divided into tranches of approximately 211,000 shares each, settling on the twenty consecutive trading days prior to the date of maturity of the Company's convertible notes. Thus, on each settlement date, approximately 211,000 shares would be settled, assuming a volume-weighted average price on such settlement date of $23.085. Assuming a volume-weighted average price of $23.085, the hedge counterparty would deliver to the Company approximately 91,904 shares on each settlement date, calculated as follows: 211,000 x ($23.085 - $13.03)/$23.085 = 91,904.

The following table outlines the effective interest rate, contractually stated interest costs, and costs related to the amortization of issuance costs for the Company's 2013 convertible senior notes during the three and nine months ended September 30, 2010 and 2009:

	For the Three Months Ended						For the Nine Months Ended
	September 30,						September 30,
	2010			2009			2010			2009
Effective interest rate	3.64		%	3.64		%	3.64		%	3.64		%
Contractually stated interest costs	$	344		$	344		$	1,031		$	1,031
Amortization of interest costs	$	112		$	112		$	336		$	336

As of September 30, 2010 and December 31, 2009, the Company had outstanding 2013 convertible senior notes with a face value of $50.0 million. As of September 30, 2010 and December 31, 2009, the fair value of the Company's 2013 convertible senior notes was $49.0 million and $44.8 million, respectively.

Note 10 - Commitments and Contingencies

Adverse Purchase Commitments

The Company is contractually obligated to reimburse its contract manufacturers for the cost of excess inventory used in the manufacture of the Company's products, if there is no alternative use. This liability, referred to as adverse purchase commitments, is provided for in other accrued liabilities in the accompanying Consolidated Balance Sheets. Estimates for adverse purchase commitments are derived from reports received on a quarterly basis from the Company's contract manufacturers. Increases to this liability are charged to cost of goods sold. When and if the Company takes possession of inventory reserved for in this liability, the liability is transferred from other accrued liabilities to the excess and obsolete inventory valuation allowance. Adverse purchase commitments amounted to $1.6 million and $1.8 million at September 30, 2010 and December 31, 2009, respectively. For the three months ended September 30, 2010 and 2009, the Company recorded a provision for adverse purchase commitments of $203,000and $187,000, respectively. For the nine months ended September 30, 2010 and 2009, the Company recorded a net provision for adverse purchase commitments of $264,000 and$612,000, respectively.

Guarantees and Indemnification Obligations

As permitted under Oregon law, the Company has agreements whereby it indemnifies its officers, directors and certain finance employees for certain events or occurrences while an officer, director or employee is or was serving in such capacity at the request of the Company. The term of the indemnification period is for the officer's, director's or employee's lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer insurance policy that limits its exposure and enables the Company to recover a portion of any future amounts paid. To date, the Company has not incurred any costs associated with these indemnification agreements. Accordingly, the Company has not recorded any liabilities for these agreements as of September 30, 2010.

The Company enters into standard indemnification agreements in its ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company's business partners or customers, in connection with patent, copyright or other intellectual property infringement claims by any third party with respect to the Company's current products, as well as claims relating to property damage or personal injury resulting from the performance of services by the Company or its subcontractors. The maximum potential amount of future payments the Company could be required to make under these

15

indemnification agreements is generally limited. To date, the Company has not had any claims relating to such indemnity agreements.

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

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

	For the Nine Months Ended
	September 30,
	2010			2009
Warranty liability balance, beginning of the period	$	2,810		$	3,072
Product warranty accruals	2,739			2,960
Utilization of accrual	(2,678		)	(3,212		)
Warranty liability balance, end of the period	$	2,871		$	2,820

The warranty liability balance is included in other accrued liabilities in the accompanying Consolidated Balance Sheets as of September 30, 2010 and December 31, 2009.

Note 12 — Income Taxes

The Company's effective tax rates for the three and nine months ended September 30, 2010 and 2009, differ from the statutory rate primarily due to a full valuation allowance provided against its United States (“U.S.”) net deferred tax assets, Canadian research and experimental development claims, the impact of stock option expense, the amortization of goodwill for tax purposes, the discrete adjustments related to uncertain tax positions and taxes on foreign income that differ from the U.S. tax rate.

The Company utilizes the asset and liability method of accounting for income taxes. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based upon the Company's review of all positive and negative evidence, including its projected three year U.S. cumulative pre-tax book loss and taxable loss, it concluded that a full valuation allowance should continue to be recorded against its U.S. net deferred tax assets at September 30, 2010. In certain other foreign jurisdictions, where the Company does not have cumulative losses or other negative evidence, the Company had net deferred tax assets of $16.9 million and $16.8 million at September 30, 2010 and December 31, 2009, respectively. In the future, if the Company determines that it is more likely than not that it will realize its U.S. net deferred tax assets, it will reverse the applicable portion of the valuation allowance and recognize an income tax benefit in the period in which such determination is made.

The Company's unrecognized tax benefit, including interest and penalties, decreased by approximately $1.0 million during the three months ended September 30, 2010. The decrease was primarily due to a reduction in unrecognized tax benefits, including interest and penalties, related to the expiration of the statute of limitations. This decrease was partially offset by an increase in unrecognized tax benefits of $400,000 associated with uncertain tax positions. The ending balances for the unrecognized tax benefits and related interest and penalties, were approximately $1.4 million, $22,000 and $27,000, respectively, at September 30, 2010. The Company anticipates recognizing unrecognized tax benefits and accrued interest and penalties of approximately $1.2 million, $22,000 and $27,000, respectively, due to anticipated closure of certain income tax audits and the expiration of the statute of limitations within the next twelve months.

During the three months ended March 31, 2010, the IRS completed its examination of the 2007 and 2008 tax years. The Company agreed with the IRS proposed adjustment in full and paid the additional tax and interest assessments of $148,000 and $3,000, respectively. During the three months ended June 30, 2010, the French tax authority completed its examination of the Company's branch operations in France for the 2007 and 2008 tax years with no income tax adjustment. The Company is currently under examination by the Canada Revenue Agency for tax years 2006 through 2008. To date, no official proposed adjustment has been made by the Canadian tax authorities and the Company believes that it has adequately provided for uncertain tax positions at September 30, 2010. However, should the Company experience an unfavorable outcome; it could have a material impact on its results of operations, financial position, and cash flows. The Company is not currently under examination by tax authorities in any other states or foreign jurisdictions.

Note 13 — Stock-based Compensation

Note 14 — Hedging

The Company’s activities expose it to a variety of market risks, including the effects of changes in foreign currency exchange rates. The Company manages these risks through the use of forward exchange contracts, designated as foreign-currency cash flow hedges, in an attempt to reduce the potentially adverse effects of foreign currency exchange rate fluctuations that occur in the normal course of business. As such, the Company’s hedging activities are all employed solely for risk management purposes as defined in GAAP for derivative instruments and hedging activities. All hedging transactions are conducted with, in the opinion of management, financially stable and reputable financial institutions. For the year ended December 31, 2009 and for the three and nine months ended September 30, 2010, the only hedge instruments executed by the Company are associated with its exposure to fluctuations in the Canadian Dollar which result from obligations such as payroll and rent paid in Canadian Dollars.

These derivatives are recognized on the balance sheet at their fair value. Unrealized gain positions are recorded as other current assets and unrealized loss positions are recorded as other current liabilities. Changes in the fair values of the outstanding derivatives that are highly effective are recorded in other comprehensive income until net income is affected by the variability of the cash flows of the hedged transaction. Typically, hedge ineffectiveness could result when the amount of the Company’s hedge contracts exceed the Company’s forecasted or actual transactions for which the hedge contracts were designed to hedge. Once a hedge contract matures the associated gain (loss) on the contract will remain in other comprehensive income until the underlying hedged transaction affects net income (loss), at which time the gain (loss) will be recorded to the expense line item being hedged, which is primarily R&D. The Company only enters into derivative contracts in order to hedge foreign currency exposure. If the Company entered into a contract for speculative reasons or if the Company’s current hedge position becomes ineffective, changes in the fair values of the derivatives would be recognized in earnings in the current period.

The Company assesses, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the cash flows of hedged items and whether those derivatives are expected to remain highly effective in future periods. For the three and nine months ended September 30, 2010 and for the year ended December 31, 2009, the Company had no hedge ineffectiveness.

During the three months ended September 30, 2010, the Company entered into 12 new foreign currency forward contracts, with total contractual values of $2.3 million. During the three months ended September 30, 2009, the Company entered into 12 new foreign currency forward contracts, with a total contractual value of $1.8 million. During the nine months ended September 30, 2010, the Company entered into 44 new foreign currency forward contracts, with total contractual values of $6.8 million. During the nine months ended September 30, 2009, the Company entered into 36 new foreign currency forward contracts, with a total contractual value of $8.5 million.

Over the next twelve months, the Company expects to reclassify into earnings a gain of approximately $243,000, currently recorded as other comprehensive income, as a result of the maturity of currently held forward exchange contracts.

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

Item 2.Management's Discussion and Analysis of Financial Condition and Results of Operations

Introduction and Overview

RadiSys Corporation is a leading provider of innovative hardware and software platforms for next generation IP-based wireless, wireline and video networks. RadiSys products include its market leading Advanced Telecommunications Computing Architecture ("ATCA") and Internet Protocol ("IP") Media Server platforms as well as application software for new IP-based communications services. These products enable customers to bring more new high-value applications and services to market faster with a lower investment. RadiSys products are used in a wide variety of applications including 3G/4G/long term evolution ("LTE") wireless voice, data and video, Femtocell, voice over internet protocol ("VoIP") and Video over IP communications and conferencing, voice quality enhancement ("VQE"), and secure defense communications. Unless required by context, or as otherwise indicated, “we,” “us,” “our” and similar terms, as well as references to the “Company” and “RadiSys” refer to RadiSys Corporation and include all of our consolidated subsidiaries.

Our Markets

We provide application-ready software and hardware platforms to the following two markets:

Communications Networks

The communications networks market is comprised of two product categories: next-generation and legacy/traditional communication networking products. Included in our next-generation communications product group are ATCA and media server products. Included in our legacy/traditional product group are our legacy/traditional wireless products and all other communications networks products that are not included in the next-generation communications group.

We enable applications in the ATCA market such as 3G/4G/LTE wireless voice, data and video, Femtocell, VoIP and Video over IP communications and conferencing, VQE, WiMax, IP Video ("IPTV") and secure defense communications, among others.

We enable applications in the media server market such as audio conferencing, network voice services, unified messaging, video services and VQE.

Commercial Systems

The commercial market consists primarily of solutions and systems for the medical imaging, test and measurement, and military/aerospace submarkets. Specific applications include:

•     Medical Imaging: X-Ray machines, MRI scanners, CT scan imaging equipment and ultrasound equipment;

•     Test and Measurement: network and logic analyzers, network and production test equipment; and

•     Military/aerospace: ruggedized terminals, small unmanned ground vehicles and other military applications.

Market Drivers

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

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

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

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

•     Continued emergence, growth and evolution of applications utilizing 4G or LTE, worldwide inter-operability for microwave access (“WiMAX”) networks, Femtocell Gateways, VoIP, IP Communications, Mobile Video, Video Gateways, Video Conferencing, IPTV, IP interactive voice response ("IVR")/ Voice-to-text, IP Messaging,

22

Network Surveillance, Network Security, Military/aerospace and Packet Inspection, all of which are supported by ATCA.

Our Solutions

We provide our customers with advanced infrastructure platforms that enable them to focus their resources and development efforts on their key areas of differentiation, while allowing them to provide higher value systems with a time-to-market advantage at a lower total cost.

Our customers select our solutions because we provide:

Leading, high-performance technology. We have been the first to market with many technological advancements such as the industry's first 10G and 40G common managed platforms, and we are a leader in areas such as IP conferencing and COM Express new product development. Our design capabilities extend to media processing and central processing units (“CPUs”), graphics processing units and network processing units (“NPUs”), digital signal processing and integrated software managed platforms, such as media and application servers, as well as many other areas.

Experienced technical resources. Our research and development ("R&D") staff has extensive experience in designing embedded hardware and software solutions. We believe that our customers benefit from the broad array of standards-based solutions that our R&D staff continues to develop and support.

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

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

Our Strategy

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

To develop our offering of higher value platform solutions. Historically, the majority of our revenues had been from the sale of stand-alone boards or blades. We have spent considerable resources developing application-ready platform solutions that incorporate complete hardware systems and software developed by us. We intend to increasingly focus our development efforts on moving further up the software stack, positioning us to provide more complete application-ready platforms that provide more value for our customers. These platforms provide an additional revenue opportunity for us, and we believe revenues from these products have the potential to generate higher average selling prices and higher gross margins than those provided from the sale of boards or blades alone.

To expand our global customer base. We continue to expand the number of customers that we work with, particularly as more customers become aware of the benefits of standards-based solutions. Our global reach allows us to market our solutions to most of the leading system vendors in our target markets. We are also expanding our customer base through entrance into adjacent markets like military/aerospace.

To explore new partnerships and strategic acquisitions as a means to build leadership in our target markets. We continue to investigate partnerships and strategic relationships, which can expand the number of solutions we offer and increase our market reach. We also continue to evaluate potential acquisition opportunities to acquire new capabilities, which can help us achieve our strategic goals. For example, in the last four years, we acquired Convedia Corporation or Convedia®, a closely-held vendor of IP media servers, and certain assets of the Modular Communications Platform Division (“MCPD”) business from Intel Corporation (“Intel”), which included ATCA and compact peripheral component interconnect (“PCI”) product lines. Most recently we acquired the assets of privately-held Pactolus Communications Software Company ("Pactolus"), a developer of next-generation IP communications solutions for converged time-division multiplexing/internet protocol ("TDM/IP") and session initiation protocol ("SIP") enabled VoIP networks.

Product Developments

Convedia^® Media Servers (“CMS”).

During the nine months ended September 30, 2010, we had the following significant developments associated with our media server line of products.

•     The Company has been awarded new business in North America, China and Europe. Our wins are in a wide range of applications, including voice and video services, video lawful intercept, conferencing, announcements and IVR applications. We were also awarded our first VoIP VQE win with a North American Tier 1 service provider. This was an important win for us as it expands the market for our media server products to now include VQE. In addition, a new Tier 1 equipment maker went live with the RadiSys CMS-9000 with China Mobile. Finally, we were awarded other new business for our IP Media Server product in Color Ring Back Tone (“CRBT”), conferencing and network announcement applications.

•     Our Integrated Mobile Media Server ("IMMS"), which was announced earlier this year, received the NGN 2010 Leadership Award from Technology Marketing Corporations NGN Magazine. The RadiSys IMMS is built on the Company's industry-leading IP Media Server. IMMS enhances mobile service providers' ability to grow new revenues from the expansion of 3G mobile video services and emerging 4G LTE deployments. During the third quarter we released our IMMS to a China-based Tier 1 equipment maker to begin trials.

•     The VQE feature for our media server was recognized for exceptional innovation by Unified Communications Magazine and won 2009 product of the year. This feature improves audio quality, minimizes end-to-end delay and streamlines network integration.

•     We announced real-time transcoding services for our media server product family. This transcoding capability converts one type of digital encoding standard to another, achieving interoperability among media streams using different endpoints in the network. TEMs and service providers need flexible, IP-based solutions to support the new transcoding requirements in converged IP-based mobile, NGN and IP Multimedia Subsystem networks.

•     In the first quarter of 2010, we acquired the assets of Pactolus, a developer of next-generation IP communications solutions for converged TDM/IP and SIP enabled VoIP networks. Pactolus software is used in operator-assisted and reservationless conferencing, prepaid/post-paid long distance services and is installed in over 45 telecommunications service provider customers worldwide. We believe that the acquisition will further strengthen our offering of telecom solutions.

•     We were again named the market leader in media servers for the sixth consecutive year by Infonetics Research. RadiSys' media servers captured approximately 60.0% of the total fourth quarter 2009 market and approximately 57.0% for the full year 2009, which represents an 8.0% and 10.0% gain, respectively, from 2008.

ATCA Product Family - Promentum^®

During the nine months ended September 30, 2010, we had the following significant developments associated with our ATCA line of products.

•     We introduced a new ruggedized COM Express module for deployment in harsh military/aerospace industrial environments that require extended temperature and vibration specifications. In addition, we released a new rack mount server platform with significant performance increases and improved energy efficiency for applications such as medical imaging and video streaming.

Financial Results

During the third quarter of 2010, total revenue increased by $4.7 million, compared to the same period in 2009.  The increase was primarily the result of continued growth from our Next-Generation product revenue, which grew 42.5% compared to the prior year.  This growth is due to prior design wins moving into our customers deployment phase and ramping volumes as a result.  The increase in third quarter revenues was also driven by a 19.3% improvement in revenues from our Commercial products compared to the same quarter in 2009.  These improvements were partially offset by the maturity of legacy/traditional communications networks products leading to a decline in revenue from this category of 23.8% compared to the same quarter in 2009.  For the

25

nine months ended September 30, 2010, we are seeing the same trends seen in the three-month comparison with a larger decline in revenues from legacy/traditional communications networks products leading to a decline in total revenue of 3.8% compared to the same nine-month period in 2009. 

Operating income increased by $2.8 million and $5.1 million for the three and nine months ended September 30, 2010, respectively, as compared to the same periods in 2009. We went from a net operating loss to a net operating income position primarily due to, and as a result of, our restructuring activities in 2009.  The restructuring charge for the nine months ended September 30, 2009 of $4.8 million reduced operating income for the period compared to the same period in 2010, but also allowed the company to reduce R&D expenses in 2010.  R&D expenses have declined by $2.5 million in the nine months ended September 30, 2010, compared to the same period in the prior year. 

For the three months ended September 30, 2010, net income was $2.2 million compared to a net loss of $832,000 for the three months ended September 30, 2009. The improvement in net income was due to growth in revenue coupled with improved gross margins and lower operating expenses. Net income was $1.7 million for the nine months ended September 30, 2010 compared to a net loss of $43.0 million for the nine months ended September 30, 2009. The loss in 2009 was primarily the result of income tax expense of $42.0 million associated with the establishment of a valuation allowance for our U.S. deferred tax assets.  

Cash and cash equivalents amounted to $133.3 million and $100.7 million at September 30, 2010 and December 31, 2009, respectively. The increase in cash and cash equivalents during the nine months ended September 30, 2010, was primarily driven by positive cash flows from operating activities in the amount of $19.3 million. In addition, net cash flows from the exercise of our settlement right with our investment bank, UBS, along with proceeds from calls of our auction rate securities ("ARS"), totaled $20.9 million after we paid down our line of credit with UBS. These positive cash inflows were offset by our purchase of the assets of Pactolus for $3.4 million along with capital expenditures in the amount of $3.3 million during the nine months ended September 30, 2010.

Critical Accounting Policies and Estimates

We reaffirm our critical accounting policies and use of estimates as reported in our Annual Report on Form 10-K for the year ended December 31, 2009. There have been no significant changes during the three months ended September 30, 2010 to the items that we disclosed as our critical accounting policies and estimates in Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 except as discussed below.

Revenue Recognition

Multiple Element Arrangements

A significant portion of our revenue relates to product sales for which revenue is recognized upon shipment, with limited judgment required related to product returns. The software content included in certain components of ATCA systems and CMS is considered to be more than incidental and these arrangements generally include multiple elements such as hardware and technical support services as well as software upgrades or enhancements on a when and if available basis. Arrangements that include multiple elements require significant management judgment to evaluate the effective terms of agreements and our performance commitments and to determine the fair value of the various deliverables under the arrangement. During the first quarter of 2010 we elected early adoption of ASU No. 2009-13, “Multiple-Deliverable Revenue Arrangements — a consensus of the FASB Emerging Issues Task Force” ("ASU 2009-13") and ASU No. 2009-14, “Certain Arrangements That Include Software Elements,” (amendments to FASB ASC Topic 985, Software) (“ASU 2009-14”). Adoption of ASU 2009-13 and ASU 2009-14 allows us to meet separation criteria required for multiple element arrangements where we could not previously establish a fair value for one or more of the relevant deliverables. Previously, when we could not establish fair value for certain technical support agreements all revenue was deferred. These revenues were then recognized over the appropriate period, generally coinciding with an explicit or implied support period, or in some cases deferred until all elements of the arrangement had been delivered. Under ASU 2009-13, overall consideration is allocated among the separate units of accounting based on their relative fair value. This will result in the ability to recognize each unit of accounting upon delivery. Revenue for hardware, which includes software that is considered more than incidental, will be recognized upon delivery whereas technical support services will be recognized over the applicable service period.

ASU 2009-13 provides a fair value hierarchy in order to determine the appropriate relative fair value for each element of an arrangement. When available, we use vendor specific objective evidence (“VSOE”) to determine the estimated selling price. In the absence of VSOE or third-party evidence ("TPE") for a delivered element, we then use an estimated selling price in order to determine fair value. Estimated selling prices represent our best estimate of the price at which we would transact if the deliverables were sold on a standalone basis. For technical support services, we generally determine our selling price based on VSOE as supported by substantive renewal rates in the related service agreements. In certain instances where we have no service agreement

26

or VSOE cannot be established, we then rely upon our estimated selling price for such deliverables as TPE is generally not available due to the unique company-specific terms surrounding such service agreements. In establishing an appropriate estimated selling price for these technical support agreements, we considered entity specific factors such as our historical and projected costs, historical and projected revenues, and profit objectives. We also considered market specific factors when establishing reasonable profit objectives.

The transition guidance provided within ASU 2009-13 is only allowed to be applied to new or substantially modified arrangements. No previously existing arrangements were modified during the quarter of adoption and therefore existing arrangements were not effected by ASU 2009-13. This guidance was applied to new revenue arrangements arising in the nine months ended September 30, 2010 where tangible products were bundled with technical support services.

Adoption of ASU 2009-13 and ASU 2009-14 has not materially affected our consolidated financial statements for the three and nine months ended September 30, 2010.

Communications Networks Product Group

Revenues in the communications networks product group increased by $1.5 million, or 2.8%, to $55.4 million for the three months ended September 30, 2010, from $53.9 million for the three months ended September 30, 2009. For the nine months ended September 30, 2010, revenues in the communications networks product group decreased by $20.0 million, or 11.1%, to $161.2 million from $181.2 million for the same period in 2009. The decrease was driven by the maturity of our legacy/traditional communications networks products, which resulted in a decline in revenue of $7.7 million or 23.8% and $36.6 million or 34.0% for the three and nine months ended September 30, 2010, respectively, as compared with the same periods in 2009. Partially offsetting the decline was the transition to next-generation communications networks products by some of these customers. Revenues from our next-generation communications networks products increased by $9.2 million or 42.5%, in the three months ended September 30, 2010, compared to the same period in 2009. For the nine months ended September 30, 2010, revenues from our next-generation communications networks product group increased by $16.5 million or 22.5%, as compared to the same period in 2009. Increased revenues from our next-generation communications networks products were primarily driven by increased deployments during the three and nine months ended September 30, 2010.

Commercial Products Group

Revenues in our commercial products group increased by $3.2 million or 19.3%, to $19.7 million for the three months ended September 30, 2010 from $16.5 million for the three months ended September 30, 2009. For the nine months ended September 30, 2010, revenues in our commercial products group increased by $11.4 million or 25.3%, to $56.3 million from $44.9 million for the nine months ended September 30, 2009. Increased revenues from the commercial products group were driven by increased medical product revenues, which increased by $1.7 million or 25.7% and $6.4 million or 35.1% for the three and nine months ended September 30, 2010, respectively, as compared to the same periods in 2009. In addition, revenues from our other commercial products category increased by $1.5 million or 14.9% and $5.0 million or 18.6% for the three and nine months ended September 30, 2010, respectively, as compared to the same periods in 2009. Revenues from medical and other commercial products grew primarily due to increased customer spending driven by an overall improvement in the economy and the healthcare sector in particular as compared to the same periods in 2009.

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

Revenue by Geography

The following tables outline overall revenue dollars and the percentage of revenues, by geographic region, for the three and nine months ended September 30, 2010 and 2009:

North America. From a geographic perspective, revenues from North America increased by $3.5 million or 16.4%, to $24.7 million for the three months ended September 30, 2010, from $21.3 million for the three months ended September 30, 2009. Revenues from North America increased by $5.8 million or 8.5%, to $74.7 million for the nine months ended September 30, 2010, from $68.9 million for the nine months ended September 30, 2009. The overall increase in revenue dollars and increase in the percentage of revenues from North America for the three and nine months ended September 30, 2010, compared to the same periods in 2009, were primarily due to an increase in North American deployments of our next-generation communications networks products as well as increased revenues from our commercial products.

EMEA. During the three months ended September 30, 2010, revenues from EMEA increased by $4.3 million or 26.0%, as compared to the same period in 2009. This increase was driven by increased revenues from both our next-generation communications networks and medical products. Increased EMEA revenues for our next-generation communications network and medical products were partially offset by decreased revenues from our legacy/traditional products in the three months ended September 30, 2010, compared to 2009. During the nine months ended September 30, 2010, revenues from the EMEA region declined by $1.6 million, compared to the same period in 2009. This decrease was driven by the maturity of our legacy/traditional communications networks products. Decreased EMEA revenues for our legacy/traditional products were partially offset by increased revenues from our next-generation communications networks products along with increased revenues from our medical products.

Asia Pacific. Revenues from the Asia Pacific region declined by $3.1 million and $12.9 million during the three and nine months ended September 30, 2010, respectively, as compared to the same periods in 2009. As a percent of total revenues Asia Pacific declined 7.0 percentage points and 4.2 percentage points for the three and nine months ended September 30, 2010, respectively, as compared to the same periods in 2009. These declines were due to decreased revenues from our legacy/traditional communications networks products.

Gross Margin. Gross margin as a percentage of revenues increased 0.9 percentage points, to 30.3% for the three months ended September 30, 2010, from 29.4% for the three months ended September 30, 2009. The increase in our gross margin during the three months ended September 30, 2010, was driven by favorable changes in our product mix. During the three months ended September 30, 2010, we derived 41.1% of our revenues from our next-generation communications networks products up 10.4 percentage points from 30.7% in the three months ended September 30, 2009. Favorable changes to our product mix were partially offset by increased manufacturing and operational costs including increased charges for excess and obsolete inventory. Specifically, excess and obsolete inventory charges increased by $346,000 during the three months ended September 30, 2010, as compared to same period in 2009.

Gross margin as a percentage of revenues decreased 0.5 percentage points, to 30.1% for the nine months ended September 30, 2010, from 30.6% for the nine months ended September 30, 2009. This decrease was largely driven by unfavorable changes in our product mix along with increased amortization of purchased technology. These unfavorable changes to gross margin as a percentage of revenue were partially offset by lower manufacturing and operational costs including decreased charges for excess and obsolete inventory as well as a $385,000 gain from the disposal of manufacturing equipment during the nine months ended September 30, 2010. During the nine months ended September 30, 2009 we had a more favorable product mix as compared to 2010 due to a larger volume of sales of our Media Server product line which resulted from the timing of shipments of these products

29

in 2009. Amortization of purchased technology increased by $161,000 to $5.0 million in the nine months ended September 30, 2010 from $4.9 million in the nine months ended September 30, 2009. This was driven by the amortization of intangible assets from our purchase of the assets of Pactolus. Lower manufacturing and operating costs were the result of continued realization of internal process improvements implemented over the last few years coupled with benefits from our transition to a fully outsourced manufacturing model. Specifically, charges related to excess and obsolete inventory decreased by $477,000 during the nine months ended September 30, 2010, respectively, as compared to the same period in 2009. The gain from the disposal of manufacturing equipment was a result of our transition to a fully outsourced manufacturing model and the sale of fully depreciated manufacturing equipment.

Research and Development. R&D expenses consist primarily of salary, bonuses and benefits for product development staff, and cost of design and development supplies and equipment, net of reimbursements for nonrecurring engineering services. R&D expenses decreased $168,000, or 1.7%, to $9.9 million for the three months ended September 30, 2010 from $10.0 million for the three months ended September 30, 2009. For the nine months ended September 30, 2010, R&D expenses decreased $2.5 million, or 7.9%, to $29.2 million from $31.7 million for the nine months ended September 30, 2009. This decrease was primarily the result of lower incentive and stock compensation costs, which decreased by $178,000 or 19.3% and $993,000 or 30.1% for the three and nine months ended September 30, 2010, respectively, as compared to the same periods in 2009. In addition, payroll and payroll related costs decreased by $362,000 for the nine months ended September 30, 2010, as compared to the same period in 2009. Lower stock and incentive compensation, as well as lower payroll costs, resulted from our transition to lower cost regions along with a lower payout factor for incentive compensation. Further contributing to the decrease were lower project costs, which decreased by $496,000 during the nine months ended September 30, 2010, as compared to the same period in 2009. Offsetting these decreases were increased costs related to the integration of Pactolus along with increased travel expenses.

Selling, General, and Administrative. Selling, general and administrative (“SG&A”) expenses consist primarily of salary, commissions, bonuses and benefits for sales, marketing, executive and administrative personnel, as well as professional services and costs of other general corporate activities. SG&A expenses increased by $265,000 or 2.4%, to $11.2 million for the three months ended September 30, 2010 from $11.0 million for the three months ended September 30, 2009. The increase in SG&A costs during the three months ended September 30, 2010 was primarily due to increased travel expenses of $239,000, increased marketing costs of $172,000, as well as a reallocation of expenses associated with unused manufacturing space totaling $129,000. Increased travel expenses were associated with increased sales and marketing activities as compared to the same period in the prior year. Expenses associated with unused manufacturing space include rent and other related facilities costs that were previously charged to cost of goods sold and have resulted from our transition to a fully outsourced manufacturing model. These increases were offset by decreased legal fees as well as rental expenses, which collectively decreased by $327,000 in the three months ended September 30, 2010, as compared to same period in 2009.

SG&A expenses decreased by $104,000 or 0.3%, to $34.0 million for the nine months ended September 30, 2010 from $34.1 million for the nine months ended September 30, 2009. The decrease in SG&A costs for the nine months ended September 30, 2010, as compared to the same period in 2009, was driven by lower costs related to incentive compensation, stock compensation and sales commissions. This decrease in compensation related costs primarily resulted from restructuring activities undertaken over the past year. Partially offsetting these declines were increased costs for travel and marketing which resulted primarily from increased sales and marketing activities as compared to the same period in 2009. Additionally, for the nine months ended September 30, 2010, SG&A includes the allocation of costs associated with unused manufacturing space, as described above, in the amount of $629,000 which was previously charged to cost of goods sold. We also incurred increased professional service fees, during the nine months ended September 30, 2010, primarily related to our acquisition of Pactolus.

Stock-based Compensation Expense. Stock-based compensation expense consists of amortization of stock-based compensation associated with stock options and restricted stock units issued under the RadiSys Corporation 2007 Stock Plan and shares issued to employees under the employee stock purchase plan (“ESPP”). Stock-based compensation expense decreased by $549,000 or 27.6%, to $1.4 million for the three months ended September 30, 2010 from $2.0 million for the three months ended September 30, 2009. Stock-based compensation expense decreased by $1.8 million or 27.2%, to $4.9 million for the nine months ended September 30, 2010 from $6.7 million for the nine months ended September 30, 2009. One of the primary reasons for the decrease in stock-based compensation expense was our restructuring activities that have occurred over the past year. As a result of our restructuring activities many awards have been forfeited and there has been a decrease in the participation in our ESPP. During the three and nine months ended September 30, 2010 stock-based compensation related to our ESPP decreased by $437,000 and $1.3 million, respectively, as compared to the same periods in 2009. In addition to lower participation, the decline in ESPP expense was also due to a liquidity discount applied to the stock-based compensation calculation to reflect a one year holding period that was added to the plan at the end of 2009. The liquidity discount accounted for $50,000 and $248,000 of the decrease in ESPP related stock-based compensation for the three and nine months ended September 30, 2010, respectively, compared to the same periods in 2009. Partially offsetting these declines was $496,000 and $1.4 million in additional stock-based compensation during the three and nine months ended September 30, 2010, associated with shares granted from our long-term incentive plan in the fourth quarter of 2009.

Intangible Assets Amortization. Intangible assets consist of purchased technology, patents and other identifiable intangible assets. Intangible assets amortization expense included within operating expenses was $192,000 and $647,000 for the three months ended September 30, 2010 and 2009, respectively. Intangible assets amortization expense included within operating expenses was $538,000 and $1.9 million for the nine months ended September 30, 2010 and 2009, respectively. Intangible assets amortization decreased due to assets that became fully amortized during the fourth quarter of 2009. We perform reviews for impairment of the purchased intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Restructuring and Other Charges. We evaluate the adequacy of the accrued restructuring and other charges on a quarterly basis. As a result, we record certain reclassifications and reversals to the accrued restructuring and other charges based on the results of the evaluation. The total accrued restructuring and other charges for each restructuring event are not affected by reclassifications. Reversals are recorded in the period in which we determine that expected restructuring and other obligations are less than the amounts accrued. During the three and nine months ended September 30, 2010, we recorded restructuring and other charges and reversals as described below.

First Quarter 2009 Restructuring. During the first quarter of 2009, we initiated a restructuring plan that included the elimination of 29 positions. The restructuring was initiated to align our costs with our annual operating plan. Included in these costs were charges related to the modification of equity awards to certain employees included in this restructuring activity. During the three months ended September 30, 2009, we incurred $4,000 in additional restructuring charges, which were comprised entirely of employee payroll related severance costs. During the nine months ended September 30, 2010, we recorded a net reversal of $85,000 of previously recorded expenses resulting primarily from the re-assignment of employees initially included in the restructuring plan. During the nine months ended September 30, 2009, we incurred a total of $1.5 million in restructuring charges, which were comprised almost entirely of employee payroll related severance costs. As of September 30, 2010, all activities associated with this restructuring were completed.

Second Quarter 2009 Restructuring.     During the three months ended September 30, 2010, we recorded a net reversal of $42,000, which primarily consisted of a reversal of $65,000 in costs associated with employee severance, healthcare benefits, and associated payroll costs. This was driven by a change in previously estimated costs associated with this restructuring plan. In addition, we incurred $23,000 in facilities related costs from our transition to a fully outsourced manufacturing model. During the three months ended September 30, 2009, we incurred an additional $171,000 in costs consisting of equipment moving fees along with other facilities related charges.

During the nine months ended September 30, 2010, we incurred $371,000 in additional expenses while we reversed $342,000 in previously estimated amounts associated with the second quarter of 2009 restructuring plan. The additional costs consisted of $219,000 in employee severance, healthcare benefits and associated payroll costs along with facilities related costs of $152,000. Reversals consisted of $314,000 in previously estimated employee severance, healthcare benefits and associated payroll costs primarily associated with retaining employees in new roles with the Company. In addition, we reversed $28,000 in facilities related expenses. During the nine months ended September 30, 2009, we incurred $3.2 million in restructuring expenses, which consisted of accrued severance obligations, healthcare benefits, relocation incentives and related payroll taxes as well as facilities related charges. All activities associated with this restructuring plan are expected to be complete by the fourth quarter of 2010.

Fourth Quarter 2009 Restructuring. During the three months ended September 30, 2010, we recorded a net reversal of $181,000 in costs primarily associated with employee severance, healthcare benefits, and related payroll costs. Specifically, we reversed $192,000 in previously accrued amounts for employee severance, healthcare benefits, and associated payroll costs primarily related to changes in previously estimated expenses. In addition, a portion of these reversals relate to employees who will now be retained in new roles. These reversals were offset by additional expenses related to legal fees and foreign currency adjustments, which collectively totaled $9,000. During the nine months ended September 30, 2010, we recorded a net reversal of

31

$138,000 in previously accrued costs associated with this restructuring plan. Specifically, we reversed previously accrued costs for employee severance, healthcare benefits and related payroll costs in the amount of $231,000 primarily related to changes in previously estimated expenses. In addition, a portion of these reversals relate to employees who will now be retained in new roles. Offsetting these reversals were changes to previously estimated amounts for employee severance, healthcare benefits and related payroll costs in the amount of $66,000 along with additional costs for legal fees and foreign currency adjustments collectively totaling $27,000. We expect all activities associated with this restructuring plan to be completed by the end of 2011.

Interest Expense. Interest expense includes interest incurred on our convertible notes and our lines of credit. Interest expense decreased $136,000, or 22.7%, to $462,000 during the three months ended September 30, 2010 from $598,000 during the three months ended September 30, 2009. Interest expense decreased $206,000, or 11.5%, to $1.6 million during the nine months ended September 30, 2010 from $1.8 million during the nine months ended September 30, 2009. The decrease in interest expense during the three and nine months ended September 30, 2010, compared to the same periods in 2009, was driven by the payoff of our revolving line of credit.

Interest Income. Interest income decreased $118,000, or 66.7%, to $59,000 for the three months ended September 30, 2010 from $177,000 for the three months ended September 30, 2009. Interest income decreased $262,000, or 31.6%, to $566,000 for the nine months ended September 30, 2010 from $828,000 for the nine months ended September 30, 2009. Interest income decreased largely as a result of our exit from the ARS market upon execution of our settlement right with UBS.

Income Tax Provision. We recorded a tax benefit of $884,000 and $646,000 for the three months ended September 30, 2010 and 2009, respectively. We recorded a tax benefit of $920,000 and a tax provision of $39.1 million for the nine months ended September 30, 2010 and 2009, respectively. We expect the effective tax rate for the twelve months ending December 31, 2010 to be a benefit of approximately 103.7% as compared to an expense of 1,217.3% for the twelve months ended December 31, 2009. The anticipated decrease in the effective tax rate is primarily due to discrete items related to the full valuation allowance against our U.S. net deferred tax assets, the revaluation of our Canadian net deferred tax assets for the year ended December 31, 2009 and recognition of unrecognized tax benefit, accrued interest and penalties due to the expiration of the statute of limitations.

In the future, if we determine that it is more likely than not that we will realize our U.S. net deferred tax assets, we will reverse the applicable portion of the valuation allowance and recognize an income tax benefit in the period in which such determination is made. The 2010 estimated effective tax rate is based on current tax law and the current expected income, by tax jurisdiction, and assumes that we will continue to receive the tax benefits associated with certain income from foreign jurisdictions. The tax rate may be affected by potential acquisitions, restructuring events or divestitures, the jurisdictions in which profits are determined to be earned and taxed and the ability to realize deferred tax assets.

 Cash and cash equivalents increased by $32.6 million to $133.3 million at September 30, 2010 from $100.7 million at December 31, 2009. Activities impacting cash and cash equivalents are as follows:

Cash Flows

	For the Nine Months Ended
	September 30,
	2010			2009
	(In thousands)
Cash provided by operating activities	$	19,254		$	14,876
Cash provided by (used in) investing activities	52,768			(2,135		)
Cash (used in) provided by financing activities	(39,486		)	5,249
Effects of exchange rate changes	49			142
Net increase in cash and cash equivalents	$	32,585		$	18,132

During the nine months ended September 30, 2010 and 2009, we used $3.3 million and $2.4 million, respectively, for capital expenditures. During the nine months ended September 30, 2010, capital expenditures consisted primarily of additions associated with our transition to lower cost geographies as well as upgrades and expansion of our internal infrastructure. During the nine months ended September 30, 2009, capital expenditures consisted primarily of upgrades to our internal infrastructure along with expenditures associated with our transition to lower cost geographies.

The increase in cash provided by investing activities was the result of gross proceeds from ARS investments purchased from UBS through the exercise of the Company's settlement right or from the ARS being called by the original issuer. Proceeds from ARS activities totaled $62.2 million, which were partially offset by the acquisition of Pactolus' assets for $3.4 million in cash.

During the nine months ended September 30, 2010 we used net cash totaling $39.5 million for financing activities. This was due to net repayments of $41.3 million on our UBS revolving line of credit.

During the nine months ended September 30, 2010 and 2009, we received $2.1 million and $4.0 million, respectively, in proceeds from the issuance of common stock through our stock compensation plans.

Changes in foreign currency rates unfavorably impacted beginning cash balances during the nine months ended September 30, 2010 by $49,000. Due to our international operations where transactions are recorded in functional currencies other than the U.S. Dollar, the effects of changes in foreign currency exchange rates on existing cash balances during any given period results in amounts on the consolidated statements of cash flows that may not reflect the changes in the corresponding accounts on the consolidated balance sheets.

As of September 30, 2010 and December 31, 2009, working capital was $147.0 million and $140.4 million, respectively. Our working capital increased by $6.6 million from the balance at December 31, 2009 as our current asset and liabilities balances decreased by $31.0 million and $37.6 million, respectively. The decrease in our current asset and liabilities balances were primarily due to the settlement of our ARS balances for which proceeds were used to pay down our UBS line of credit. As of September 30, 2009 working capital was $135.7 million and the improvement in our working capital balance since September 30, 2009 was primarily due to cash generated from operations.

Investments

33

Investments consisted of the following (in thousands):

	September 30, 2010		December 31, 2009
Short-term investments (ARS)	$	—	$	54,321
UBS settlement right	—		7,833
	$	—	$	62,154

As of December 31, 2009, we held investments in ARS, the majority of which represented interests in collateralized debt obligations supported by pools of government-backed student loans with S&P AAA or Moody’s Aaa ratings at the time of purchase. During the first quarter of 2008, our portfolio of ARS investments experienced multiple failed auctions as the amount of securities submitted for sale exceeded the amount of purchase orders. An auction failure, which is not a default in the underlying debt instrument, occurs when there are more sellers than buyers at a scheduled interest rate auction date and parties desiring to sell their auction rate securities are unable to do so. During the fourth quarter of 2008, we accepted a settlement offer from UBS, associated with the failed auctions. Under the terms of the offer, we had the right to require the bank to repurchase at par value our ARS investments at any time between June 30, 2010 and June 30, 2012. During the nine months ended September 30, 2010, we exercised our settlement right with UBS and as a result the investment bank repurchased our remaining balance of ARS. As of September 30, 2010, we held no ARS investments. We recorded net gains of $21,000 associated with our settlement right during the nine months ended September 30, 2010, which are included in other income, net in the accompanying Consolidated Statement of Operations.

Lines of Credit

Silicon Valley Bank

We have a secured revolving line of credit agreement with Silicon Valley Bank (the "Agreement"). The Agreement provides us with a two-year secured revolving credit facility of $30.0 million, which is subject to a borrowing base and secured by our accounts receivable. Borrowings under the Agreement bear interest at the prime rate, which was 3.25% as of September 30, 2010, or LIBOR, which was 0.26% as of September 30, 2010, plus 1.25%, with either interest rate determined by our election. We are required to make interest payments monthly. We are further required to pay a commitment fee equal to 0.08% of the $30.0 million maximum borrowing limit on an annual basis, and to pay quarterly in arrears an unused facility fee in an amount equal to 0.375% per year of the unused amount of the facility. In addition, the Agreement provides sub-facilities for letters of credit and foreign exchange contracts to be issued on our behalf.

The Agreement requires us to make and maintain certain financial covenants, representations, warranties and other agreements that are customary in credit agreements of this type, which are disclosed in full in our annual report on Form 10-K for the year ended December 31, 2009. As of September 30, 2010, we had no outstanding balances on the line of credit or letters of credit issued on our behalf.

During the fourth quarter of 2010, we amended our revolving line of credit agreement with Silicon Valley Bank. Among other amendments, we extended the term of the agreement for another year, to September 30, 2012. Additionally, we amended the non-formula borrowing base to a maximum amount of $30.0 million as long as we maintain a minimum quarterly current ratio of 2:1. The current ratio is calculated as current assets divided by the sum of current liabilities, including the outstanding aggregate amount of borrowings and letters of credit, less deferred income.

UBS

During the fourth quarter of 2008, we accepted a settlement offer from UBS, associated with failed auctions for our previously held ARS. Under the terms of the offer, we had the right to require the bank to repurchase at par value our ARS investments at any time between June 30, 2010 and June 30, 2012. Acceptance of the offer also entitled us to receive no net cost loans from UBS, or its affiliates, for up to 75% of the market value of the Company's ARS.

On June 30, 2010, we exercised our settlement right with UBS, which resulted in the repurchase by UBS of our remaining ARS investments. On July 1, 2010, upon the settlement of the ARS investments sold to UBS, we repaid our line of credit with UBS in full. On July 2, 2010 the UBS line of credit was terminated upon completion of all of the parties' obligations.

2013 Convertible Senior Notes

During February 2008, we offered and sold in a public offering pursuant to the shelf registration statement $55.0 million aggregate principal amount of 2.75% convertible senior notes due 2013 (the “2013 convertible senior notes”). Interest is payable semi-annually, in arrears, on each August 15 and February 15, beginning on August 15, 2008, to the holders of record at the close

34

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

In connection with the issuance of the 2013 convertible senior notes, we entered into a capped call transaction with a hedge counterparty. The capped call transaction is expected to reduce the potential dilution upon conversion of the 2013 convertible senior notes in the event that the market value per share of our common stock, as measured under the terms of the capped call transaction, at the time of exercise is greater than the strike price of the capped call transaction of approximately $13.03. The strike price of the capped call transaction corresponds to the initial conversion price of the 2013 convertible senior notes and is subject to certain adjustments similar to those contained in the notes. The capped call transaction provides for net-share settlement in the event that the volume-weighted average price per share of our common stock on the settlement date exceeds the strike price of approximately $13.03 per share. In such event, the hedge counterparty would deliver to us a number of shares equal to a formula determined by the quotient resulting from (a) the shares being settled times the difference between the volume-weighted average price on the settlement date and the strike price of approximately $13.03 per share, divided by (b) the volume-weighted average price on the settlement date. If the volume-weighted average price on the settlement date equals or exceeds the cap price of $23.085 per share, the difference in (a) would be $23.085 minus $13.03, or $10.055. Because the maximum number of shares deliverable under the capped call transaction is less than the number of shares issuable upon conversion of the 2013 convertible senior notes, we refer to this effect as “dilution mitigation.” If the market value per share of our common stock exceeds the cap price of the capped call transaction of $23.085, as measured under the terms of the capped call transaction, no additional shares would be delivered under the capped call transaction, and correspondingly, the dilution mitigation under the capped call transaction will be limited, which means that there would be dilution to the extent that the then market value per share of our common stock exceeds the cap price of the capped call transaction. Although the capped call transaction covers approximately 4.2 million shares, in order to facilitate an orderly settlement process, the shares are divided into tranches of approximately 211,000 shares each, settling on the twenty consecutive trading days prior to the date of maturity of our convertible notes. Thus, on each settlement date, approximately 211,000 shares would be settled, assuming a volume-weighted average price on such settlement date of $23.085. Assuming volume-weighted average price of $23.085, the hedge counterparty would deliver to us approximately 91,904 shares on each settlement date, calculated as follows: 211,000 x ($23.085 – $13.03)/$23.085 = 91,904.

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

As of September 30, 2010, we had outstanding 2013 convertible senior notes with a face value and fair value of $50.0 million and $49.0 million, respectively. As of December 31, 2009, we had outstanding 2013 convertible senior notes with a face value and fair value of $50.0 million and $44.8 million, respectively.

Contractual Obligations

The following summarizes our contractual obligations at September 30, 2010 and the effect of such on our liquidity and cash flows in future periods (in thousands).

*	Remaining three months.
(A)	Purchase obligations include agreements or purchase orders to purchase goods or services that are enforceable and legally binding and specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions and the approximate timing of the transaction. Purchase obligations exclude agreements that are cancelable without penalty.

In addition to the above, as discussed in Note 12 - Income Taxes of the Notes to the Consolidated Financial Statements, we have approximately $1.5 million associated with unrecognized tax benefits and related interest and penalties. These liabilities are primarily included as a component of “Other accrued liabilities” in our Consolidated Balance Sheet as we anticipate that settlement of the liabilities will be within the next twelve months. We do not believe that the ultimate settlement of our obligations will materially affect our liquidity.

Off-Balance Sheet Arrangements

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

Liquidity Outlook

We believe that our current cash and cash equivalents of $133.3 million at September 30, 2010, the cash generated from operations and our line of credit facility will satisfy our short and long-term expected working capital needs, capital expenditures, stock repurchases, and other liquidity requirements associated with our existing business operations even if we are required to hold our ARS until maturity. Capital expenditures are expected to be approximately $1.0 million per quarter.

FORWARD-LOOKING STATEMENTS

This report contains some forward-looking statements that set forth anticipated results and expectations based on management’s plans and assumptions. Such statements give our current expectations or forecasts of future events; they do not relate strictly to historical or current facts. In some cases, forward-looking statements can be identified by terms such as “may,” “will,” “should,” “expect,” “plans,” “seeks,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “continue,” “seek to continue,” “intends,” or other comparable terminology. In particular, these include statements relating to:

•     expectations and goals for revenues, gross margin, R&D expenses, SG&A expenses and profits;

•     expectations about benefits from and integration of the operations, technologies, products and personnel from the acquisition of the assets of Pactolus;

•     prospective products, future performance of current products;

•     the impact of our restructuring events on future operating results;

•     currency exchange rate fluctuations, changes in tariff and trade policies and other risks associated with foreign operations;

•     our projected liquidity; and

•     matters related to the embedded system industry, including changes in industry standards, changes in customer requirements and new product introductions.

In particular, forward-looking statements in this report include discussions of our goals, including those discussions set forth in Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations." We cannot provide assurance that these goals will be achieved.

Although forward-looking statements help provide additional information about us, investors should keep in mind that forward-looking statements are only predictions, at a point in time, and are inherently less reliable than historical information. Actual results could differ materially from the anticipated results and expectations in these forward-looking statements as a result of a number of risk factors, including, among others, (a) our dependence on certain customers and high degree of customer concentration (b) the anticipated amount and timing of revenues from design wins due to our customers' product development time, cancellations or delays, (c) the current economic uncertainty and turmoil within the global financial markets, (d) currency exchange rate fluctuations, changes in tariff and trade policies and other risks associated with foreign operations; and (e) the other factors listed in our reports filed with the SEC, including those listed under "Risk Factors" in Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2009, as updated by subsequent quarterly reports on Form 10-Q. These risk factors may cause our actual results to differ materially from any forward-looking statement.

We do not guarantee future results, levels of activity, performance or achievements, and we do not assume responsibility for the accuracy and completeness of these statements. The forward-looking statements contained in this report are made and based on information as of the date of this report. We assume no obligation to update any of these statements based on information after the date of this report.

Item 3.Quantitative and Qualitative Disclosures about Market Risk

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

Interest Rate Risk. We invest excess cash in debt instruments of the U.S. Government and its agencies, and those of high-quality corporate issuers. We attempt to protect and preserve our invested funds by limiting default, market, and reinvestment risk. Investments in both fixed rate and floating rate interest earning instruments carry a degree of interest rate risk. Fixed rate securities may have their fair value adversely affected due to a rise in interest rates while floating rate securities may produce less income than expected if interest rates decline. Due to the short duration of most of the investment portfolios, an immediate 10% change in interest rates would not have a material effect on the fair value of our investment portfolio. Additionally, the interest rate changes affect the fair market value but do not necessarily have a direct impact on our earnings or cash flows. Therefore, we would not expect our operating results or cash flows to be affected, to any significant degree, by the effect of a sudden change in market interest rates on the securities portfolio. The estimated fair value of our interest bearing investments at September 30, 2010 and December 31, 2009 was $58,000 and $70.2 million, respectively. The effect of an immediate 10% change in interest rates would not have a material effect on our operating results or cash flows.

37

Foreign Currency Risk. We pay the expenses of our international operations in local currencies, namely, the Canadian Dollar, Euro, Chinese Yuan, Japanese Yen, Malaysian Ringgit, British Pound Sterling, and New Shekel. Our international operations are subject to risks typical of an international business, including, but not limited to: differing economic conditions, changes in political climate, differing tax structures, foreign exchange rate volatility and other regulations and restrictions. Accordingly, future results could be materially and adversely affected by changes in these or other factors. We are also exposed to foreign exchange rate fluctuations as the balance sheets and income statements of our foreign subsidiaries are translated into U.S. Dollars during the consolidation process. Because exchange rates vary, these results, when translated, may vary from expectations and adversely affect overall expected profitability. Foreign currency exchange rate fluctuations resulted in a net loss of $30,000 and less than $1,000 for the three months ended September 30, 2010 and 2009, respectively. Foreign currency exchange rate fluctuations resulted in a net gain of $25,000 and $5,000 for the nine months ended September 30, 2010 and 2009, respectively.

Based on our policy, we have established a foreign currency exposure management program which uses derivative foreign exchange contracts to address nonfunctional currency exposures. In order to reduce the potentially adverse effects of foreign currency exchange rate fluctuations, we may enter into forward exchange contracts. These hedging transactions limit our exposure to changes in the U.S. Dollar/Canadian Dollar exchange rate, and as of September 30, 2010, the total notional or contractual value of the contracts we held was $12.4 million. These contracts will mature over the next 20 months.

Holding other variables constant, a 10% adverse fluctuation, in relation to our hedge positions, of the U.S. Dollar relative to the Canadian Dollar would require an adjustment of $1.2 million, reversing our hedge asset and creating a hedge liability as of September 30, 2010, in the amount of $1.0 million. A 10% favorable fluctuation, in relation to our hedge positions, of the U.S. Dollar relative to the Canadian Dollar would result in an adjustment of $1.2 million and our total hedge asset as of September 30, 2010 would be $1.5 million. We do not expect a 10% fluctuation to have any impact on our operating results as the underlying hedged transactions will move in an equal and opposite direction. As of September 30, 2010, our hedged positions are associated with our exposure to movements in the Canadian Dollar. If there is an unfavorable movement in the Canadian Dollar relative to our hedged positions this would be offset by reduced expenses, after conversion to the U.S. Dollar, associated with obligations paid for in the Canadian Dollar.

Convertible Notes. The fair value of the 2013 convertible senior notes is sensitive to interest rate changes as well as our common stock price. Interest rate changes would result in an increase or decrease in the fair value of the 2013 convertible senior notes due to differences between market interest rates and rates in effect at the inception of the obligation. Unless we elect to repurchase our 2013 convertible senior notes in the open market, changes in the fair value of the senior convertible notes have no impact on our cash flows or Consolidated Financial Statements. The estimated fair value of the 2013 convertible senior notes was $49.0 million and $44.8 million at September 30, 2010 and December 31, 2009, respectively.

Item 4.Controls and Procedures

Based on their evaluation as of the end of the period covered by this report, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) are effective.

During our most recent fiscal quarter, we identified no change in our internal control over financial reporting, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

During the third quarter of 2010, we completed the process of incorporating disclosure controls and procedures of Pactolus, which was acquired effective March 11, 2010, into the Company's disclosure controls and procedures.

38

PART II. OTHER INFORMATION

Item 1A.Risk Factors

There are many factors that affect our business and the results of our operations, many of which are beyond our control. In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. Risk Factors and Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 31, 2009, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K for the year ended December 31, 2009, as updated by subsequent quarterly reports on form 10-Q, are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

39

Item 5.Other Information

On November 2, 2010, the Company amended its revolving line of credit agreement, by entering into the Sixth Amendment to Loan and Security Agreement with Silicon Valley Bank (the “Sixth Amendment”).

Pursuant to the Sixth Amendment,among other things, the Company extended the term of the agreement for another year, to September 30, 2012. Additionally, the Company amended the non-formula borrowing base to a maximum amount of $30.0 million as long as the Company maintains a minimum quarterly current ratio of 2:1. The current ratio is calculated as current assets divided by the sum of current liabilities, including the outstanding aggregate amount of borrowings and letters of credit, less deferred income.

The foregoing summary of the Sixth Amendment is not complete and is qualified in its entirety by reference to the Sixth Amendment, filed as Exhibit 10.1 to this report and is incorporated herein by reference.
