EXPLANATORY NOTE

We are filing this Form 10-K/A to correct certain clerical errors made in our financial statements contained in our Form 10-K for the fiscal year period ended February 3, 2007 filed with the Securities and Exchange Commission on April 20, 2007 (the “Original Form 10-K”). We believe our financial statements contained in the Original Form 10-K presented fairly, in all material respects, our consolidated financial position as of February 3, 2007 and January 28, 2006, and the consolidated results of our operations and our cash flows in each of the fiscal years in the three-year period ended February 3, 2007, in conformity with U.S. generally accepted accounting principles. For the sake of clarity, however, we are correcting the following clerical errors to the Original 10-K in this Amendment:

• In our consolidated Balance Sheet, we are adding disclosure regarding the number of authorized shares of preferred stock.

• In our Consolidated Statements of Shareholders’ Equity and Comprehensive Income, under our “Balance as of January 28, 2006…”, we are correcting the amounts listed in the “Total Shareholders’ Equity” column for the line items of “Compensation expenses recognized in accordance with FAS 123R” and “Fair value of vested stock options assumed from Blue7 acquisition.” The balances in this statement as of February 3, 2007 were correctly reported in the Original 10-K, including the totals of all columns of shareholders’ equity and the total Shareholders’ Equity amount.

• In our stock-based compensation discussion under Note 1 – Nature of Operations and Significant Accounting Policies to our Notes to Consolidated Financial Statements, we are correcting the amount of stock-based compensation expenses recognized under SFAS 123(R) for fiscal year 2007 from $5.1 million to $4.9 million, in order to appropriately exclude expenses related to certain non-employees. The amount of stock-based compensation awarded to non-employees has now also been separately disclosed within Note 1.

• In our stock-based compensation discussion under Note 1 – Nature of Operations and Significant Accounting Policies to our Notes to Consolidated Financial Statements, we are correcting certain amounts in the table contained under the caption, “Prior to the Adoption of SFAS 123(R).”

• In Note 11 – Current and Long-term Debt to our Notes to Consolidated Financial Statements, we are correcting the effective average interest rate we paid from January 29, 2006 to February 3, 2007 on our term loan credit facility under the Loan and Security Agreement with United Commercial Bank from 7.4% to 8.54%.

• In Note 12 – Net Income (Loss) Per Share to our Notes to Consolidated Financial Statements, we are correcting the number of dilutive shares not included in loss years for fiscal year 2006 (in thousands) from 2,255 to 2,621 and the number of excluded potential dilutive securities as of the end of fiscal year 2007 (in thousands) from 102 to 489.

• In Note 13 – Shareholders’ Equity to our Notes to Consolidated Financial Statements, we are correcting (a) all information on the line relating to outstanding options and options exercisable with a range of exercise prices from $9.89 to $9.89 and (b) the number of shares that remained available for future purchase under our employee stock purchase plan as of February 3, 2007 from 40,675 shares to 226,292 shares.

• In Note 15 – Acquisition to our Notes to Consolidated Financial Statements, we are correcting the following assumptions we used to determine the fair value of options assumed in our acquisition of Blue7 Communication: (a) expected term (in years) from 3.53 years to 5.13 years; (b) volatility from 56% to 74%; and (c) risk free interest rate from 4.44% to 4.59%.

We are including in this Form 10-K/A Part II, Item 8 – Financial Statements and Supplementary Data, Part II, Item 9A – Controls and Procedures and Part IV, Item 15 – Exhibits and Financial Statement Schedules. We have made changes, which are summarized above, only to our financial statements contained in Part II, Item 8 – Financial Statements and Supplementary Data.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We conducted an evaluation, under the supervision and with the participation of our management including our principal executive officer and principal financial officer, of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as of February 3, 2007. Based upon that evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were not effective as of February 3, 2007 because of the material weaknesses discussed below.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). Internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation and may not prevent or detect misstatements. Projections of any evaluation of effectiveness of internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, including our principal executive officer and principal financial officer, assessed the effectiveness of our internal control over financial reporting as of February 3, 2007. In making this assessment, management used the criteria set forth inInternal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). A material weakness is a control deficiency or combination of control deficiencies that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Management’s assessment identified the following control deficiencies or combination of control deficiencies that constitute material weaknesses:

Company-level controls. We did not maintain effective company-level controls as defined in the Internal Control—Integrated Framework published by COSO. These deficiencies related to each of the five components

2

of internal control as defined by COSO (control environment, risk assessment, control activities, information and communication, and monitoring). These deficiencies resulted in more than a remote likelihood that a material misstatement of our annual or interim financial statements would not be prevented or detected. Specifically,

• Our control environment did not sufficiently promote effective internal control over financial reporting throughout our organizational structure, and this material weakness was a contributing factor to the other material weaknesses described in this Item 9a;

• We had inadequate risk assessment controls, including inadequate mechanisms for anticipating and identifying financial reporting risks; and for reacting to changes in the operating environment that could have a material effect on financial reporting;

• There was inadequate communication from management to employees regarding the general importance of controls and employees duties and control responsibilities;

• We had inadequate monitoring controls, including inadequate staffing and procedures to ensure periodic evaluations of internal controls to ensure that appropriate personnel regularly obtain evidence that controls are functioning effectively and that identified control deficiencies are remediated timely;

• We had an inadequate number of trained finance and accounting personnel with appropriate expertise in U.S. generally accepted accounting principles. Accordingly, in certain circumstances, an effective secondary review of technical accounting matters was not performed;

• We had inadequate controls over our management information systems related to program changes, segregation of duties, and access controls; and

• We had inadequate access and change controls over end-user computing spreadsheets. Specifically, our controls over the completeness, accuracy, validity and restricted access and review of certain spreadsheets used in the period-end financial statement preparation and reporting process were not designed appropriately or did not operate as designed.

Controls over stock-based compensation. We had inadequate administration, supervision, and review controls over the approval and recording of stock-based compensation.

• As discussed in Note 2 in Notes to the Consolidated Financial Statements of this Form 10-K, during 2006, an internal review related to our historical stock option granting practices was carried out by our Audit Committee. As a result of the review, we reached a conclusion that incorrect measurement dates were used for financial accounting purposes for certain stock option grants made in prior periods. Therefore, we have recorded additional non-cash stock-based compensation expense and related tax effects with regard to past stock option grants, substantially all of which relate to options granted between February 1, 1997 and July 29, 2006; and

• As discussed in Note 2 in Notes to the Consolidated Financial Statements of this Form 10-K, during our fiscal 2007 audit, we determined that incorrect measurement dates were used to value stock options exchanged with the previously Blue7 employees upon the acquisition of Blue7. As a result, we restated our financial results for the first quarter of fiscal 2007 to record an increase to the purchase price of $0.7 million and an additional $0.7 million of deferred stock-based compensation expense.

We are restating previously filed annual and interim financial statements in this annual report on Form 10-K to correct the errors related to accounting for stock-based compensation.

Financial statement preparation and review procedures.We had inadequate policies, procedures and personnel to ensure that accurate, reliable interim and annual consolidated financial statements were prepared and reviewed on a timely basis. Specifically, we had insufficient: a) levels of supporting documentation; b) review and supervision within the accounting and finance departments; c) preparation and review of footnote disclosures accompanying our financial statements; and d) technical accounting resources. These deficiencies

3

resulted in errors in the financial statements and more than a remote likelihood that a material misstatement of our annual or interim financial statements would not be prevented or detected.

Inadequate reviews of account reconciliations, analyses and journal entries. We had inadequate review procedures over account reconciliations, account and transaction analyses, and journal entries. Specifically, deficiencies were noted in the following areas: a) management review of supporting documentation, calculations and assumptions used to prepare the financial statements, including spreadsheets and account analyses; and b) management review of journal entries recorded during the financial statement preparation process. These deficiencies resulted in an understatement of warranty accrual and inventory reserves, misclassification errors between R&D expenses and Cost of Goods Sold, and other errors in the financial statements. These deficiencies resulted in a more than a remote likelihood that a material misstatement of our annual or interim financial statements would not be prevented or detected.

Inadequate controls over purchases and disbursements.We had inadequate controls over the segregation of duties and authorization of purchases, and the disbursement of funds. These weaknesses increase the likelihood that misappropriation of assets and/or unauthorized purchases and disbursements could occur and not be detected in a timely manner. These deficiencies resulted in errors in the financial statements and in more than a remote likelihood that a material misstatement of our annual or interim financial statements would not be prevented or detected. Specifically,

• We had inadequate procedures and controls to ensure proper segregation of duties within our purchasing and disbursements processes and accounting systems;

• We had inadequate procedures and controls to ensure proper authorization of purchase orders; and

• We had inadequate approvals for payment of invoices and wire transfers.

Because of the weaknesses described above, management has concluded that our internal control over financial reporting was not effective as of February 3, 2007. Armanino McKenna LLP, an independent registered public accounting firm, audited management’s assessment of the effectiveness of our internal control over financial reporting. Armanino McKenna LLP issued an audit report thereon, which is included beginning on page 51 of this Annual Report on Form 10-K.

We are addressing the outstanding material weaknesses described above, as well as our control environment. We hired a qualified CFO in the first quarter of fiscal 2008. We also expect to undertake the following remediation efforts:

• Hire additional qualified personnel and other resources to strengthen the accounting, finance, and information technology organizations, and develop a plan to procure and then commence implementation of an enterprise resource planning system to replace our current system, to include appropriate information technology control;

• Adopt administration, supervision, and review controls over stock based compensation as discussed above in “Restatement of Consolidated Financial Statements” contained in Management’s Discussion and Analysis of Financial Condition and Results of Operations;

• Implement controls to ensure the periodic review of and changes to our end-user computing spreadsheets used in the period-end financial statement preparation and reporting process; and

• Review and implement appropriate vendor, purchasing, and disbursements segregation of duties controls.

These specific actions are part of an overall program that we are currently developing in an effort to remediate the material weaknesses described above. We may not have sufficient time to implement our remediation plan before testing our internal control over financial reporting for the fiscal year end 2008.

The certifications of our principal executive officer and principal financial officer required in accordance with Section 302 of the Sarbanes-Oxley Act of 2002 are attached as exhibits to this Annual Report on Form 10-K. The disclosures set forth in this Item 9A contain information concerning the evaluation of our disclosure controls and procedures and changes in internal control over financial reporting, referred to in paragraph 4 of the certifications. Those certifications should be read in conjunction with this Item 9A for a more complete understanding of the matters covered by the certifications.

Changes in Internal Control over Financial Reporting During the Fiscal Quarter Ended February 3, 2007

During the fiscal quarter ended February 3, 2007, there were no changes in our internal control over financial reporting that have materially affected, or are reasonable likely to materially affect, our internal control over financial reporting, other than those noted above.

Internal Control Enhancements Implemented During the Fiscal Year Ended February 3, 2007

During the fiscal year ended February 3, 2007, we hired a SEC reporting manager with relevant accounting experience, skills and knowledge in January 2006, and we hired a Director of Internal Audit with relevant accounting/auditing experience, skills and knowledge in May 2006, thereby increasing internal technical accounting and auditing expertise. In the first quarter of fiscal 2008, we also hired a new Chief Financial Officer. These qualified personnel are beginning to address the outstanding material weaknesses noted above.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Board of Directors and Stockholders of

Sigma Designs, Inc.

We have audited management’s assessment, included in the accompanying Management Report on Internal Control Over Financial Reporting, appearing under Item 9A, that Sigma Designs, Inc. (the “Company”) did not maintain effective internal control over financial reporting as of February 3, 2007, because of the effect of the material weaknesses identified in management’s assessment and described below, based on criteria established in Internal Control--Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment, and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

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

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

A material weakness is a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. The following material weaknesses have been identified and are included in management’s assessment as of February 3, 2007.

Company-level controls. The Company did not maintain effective company-level controls as defined in the Internal Control--Integrated Framework published by COSO. These deficiencies related to each of the five components of internal control as defined by COSO (control environment, risk assessment, control activities, information and communication, and monitoring). These deficiencies resulted in more than a remote likelihood that a material misstatement of the annual or interim financial statements would not be prevented or detected. Specifically,

• The Company’s control environment did not sufficiently promote effective internal control over financial reporting throughout its organizational structure, and this material weakness was a contributing factor to the other material weaknesses described in this report;

• The Company had inadequate risk assessment controls, including inadequate mechanisms for anticipating and identifying financial reporting risks; and for reacting to changes in the operating environment that could have a material effect on financial reporting;

• There was inadequate communication from management to employees regarding the general importance of controls and employees duties and control responsibilities;

• The Company had inadequate monitoring controls, including inadequate staffing and procedures to ensure periodic evaluations of internal controls to ensure that appropriate personnel regularly obtain evidence that controls are functioning effectively and that identified control deficiencies are remediated timely;

• The Company had an inadequate number of trained finance and accounting personnel with appropriate expertise in U.S. generally accepted accounting principles. Accordingly, in certain circumstances, an effective secondary review of technical accounting matters was not performed;

�� • The Company had inadequate controls over its management information systems related to program changes, segregation of duties, and access controls; and

• The Company had inadequate access and change controls over end-user computing spreadsheets. Specifically, the Company’s controls over the completeness, accuracy, validity and restricted access and review of certain spreadsheets used in the period-end financial statement preparation and reporting process were not designed appropriately or did not operate as designed.

Controls over stock-based compensation. The Company had inadequate administration, supervision, and review controls over the approval and recording of stock-based compensation.

• As discussed in Note 2 in Notes to the Consolidated Financial Statements of this Form 10-K, during 2006, an internal review related to the Company’s historical stock option granting practices was carried out by its Audit Committee. As a result of the review, the Company reached a conclusion that incorrect measurement dates were used for financial accounting purposes for certain stock option grants made in prior periods. Therefore, the Company recorded additional non-cash stock-based compensation expense and related tax effects with regard to past stock option grants, substantially all of which relate to options granted between February 1, 1997 and July 29, 2006.

• As discussed in Note 2 in Notes to the Consolidated Financial Statements of this Form 10-K, during our fiscal 2007 audit, the Company determined that incorrect measurement dates were used to value stock options exchanged with the previously Blue7 employees upon the acquisition of Blue7. As a result, the Company restated its financial results for the first quarter of fiscal 2007 to record an increase to the purchase price of $0.7 million and an additional $0.7 million of deferred stock-based compensation expense.

The Company is restating previously filed annual and interim financial statements in this annual report on Form 10-K to correct the errors related to accounting for stock-based compensation.

Financial statement preparation and review procedures. The Company had inadequate policies, procedures and personnel to ensure that accurate, reliable interim and annual consolidated financial statements were prepared and reviewed on a timely basis. Specifically, the Company had insufficient: a) levels of supporting documentation; b) review and supervision within the accounting and finance departments; c) preparation and review of footnote disclosures accompanying its financial statements; and d) technical accounting resources. These deficiencies resulted in errors in the financial statements and more than a remote likelihood that a material misstatement of its annual or interim financial statements would not be prevented or detected.

Inadequate reviews of account reconciliations, analyses and journal entries. The Company had inadequate review procedures over account reconciliations, account and transaction analyses, and journal entries.

Table of Contents

Specifically, deficiencies were noted in the following areas: a) management review of supporting documentation, calculations and assumptions used to prepare the financial statements, including spreadsheets and account analyses; and b) management review of journal entries recorded during the financial statement preparation process. These deficiencies resulted in an understatement of warranty accrual and inventory reserves, misclassification errors between R&D expenses and Cost of Goods Sold, and other errors in the financial statements. These deficiencies resulted in a more than a remote likelihood that a material misstatement of the Company’s annual or interim financial statements would not be prevented or detected.

Inadequate controls over purchases and disbursements. The Company had inadequate controls over the segregation of duties and authorization of purchases, and the disbursement of funds. These weaknesses increase the likelihood that misappropriation of assets and/or unauthorized purchases and disbursements could occur and not be detected in a timely manner. These deficiencies resulted in errors in the Company’s financial statements and in more than a remote likelihood that a material misstatement of its annual or interim financial statements would not be prevented or detected. Specifically,

• The Company had inadequate procedures and controls to ensure proper segregation of duties within its purchasing and disbursements processes and accounting systems;

• The Company had inadequate procedures and controls to ensure proper authorization of purchase orders; and

• The Company had inadequate approvals for payment of invoices and wire transfers.

These material weaknesses were considered in determining the nature, timing, and extent of the audit tests applied in our audit of the consolidated financial statements and financial statement schedule as of and for the year ended February 3, 2007, and this report does not affect our report dated April 20, 2007, on those financial statements and financial statement schedule.

In our opinion, management’s assessment that the Company did not maintain effective internal controls over financial reporting as of February 3, 2007, is fairly stated in all material respects, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Also in our opinion, because of the effect of the material weaknesses described above on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of February 3, 2007, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We do not express an opinion or any other form of assurance on management’s statement referring to actions taken in remediation of the material weakness in internal controls subsequent to February 3, 2007.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the accompanying consolidated balance sheets of Sigma Designs, Inc. as of February 3, 2007 and January 28, 2006 (restated), and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three years in the period ended February 3, 2007 (restated), and our report dated April 20, 2007 expressed an unqualified opinion on those financial statements.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

Sigma Designs, Inc.

We have audited the accompanying consolidated balance sheets of Sigma Designs, Inc. as of February 3, 2007 and January 28, 2006 (restated), and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three years in the period ended February 3, 2007 (restated). Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Sigma Designs, Inc. at February 3, 2007 and January 28, 2006 (restated), and the consolidated results of their operations and their cash flows for each of the three years in the period ended February 3, 2007 (restated), in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects, the information set forth therein.

As discussed in Note 2, “Restatement of Consolidated Financial Statements” the Company has restated previously issued financial statements as of January 28, 2006 and for each of the years in the two year period ended January 28, 2006.

As discussed in Note 1 to the Consolidated Financial Statements, effective January 29, 2006, the Company adopted the provision of Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Sigma Designs, Inc.’s internal control over financial reporting as of February 3, 2007, based on criteria established inInternal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 20, 2007 expressed an unqualified opinion on management’s assessment of, and an adverse opinion on the effective operation of, internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations—Sigma Designs, Inc. (the Company) specializes in silicon-based digital media processors for IP video technology, connected media players, high-definition television and PC add-in and other markets. The Company’s award-winning REALmagic^® Video Streaming Technology is used in a variety of consumer applications providing highly integrated solutions for high-quality decoding of H.264, MPEG-4, MPEG-2, MPEG-1 and Windows^® Media Video 9 (WMV9). The Company sells its products to consumer equipment manufacturers, distributors, value-added resellers and corporate customers.

Basis of Presentation—The consolidated financial statements include Sigma Designs, Inc. and its wholly owned subsidiaries in France and Hong Kong. All intercompany balances and transactions are eliminated upon consolidation.

Reclassifications—Certain reclassifications have been made to prior year balances in order to conform to the current year’s presentation.

Accounting Period—The Company’s fiscal year ends on the Saturday closest to January 31. Fiscal 2007 ended on February 3, 2007. Fiscal 2006 ended on January 28, 2006. Fiscal 2005 ended on January 29, 2005. Fiscal 2007 included 53 weeks. Fiscal 2006 and 2005 each included 52 weeks.

Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements include but are not limited to and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates used in preparing these financial statements are related primarily to estimates to determine the collectability of accounts receivable to determine the allowances against the accounts receivable balances, estimates of the market value used in calculating the value of inventory on a lower of cost or market basis, estimates used in equity award valuation and stock-based compensation calculations, estimates of expected future cash flows and useful lives used in the review for impairment of investments, goodwill, intangible assets and other long-lived assets, estimates of the Company’s ability to realize its deferred tax asset which are also used to establish whether valuation allowances are needed on those assets, and estimates related to litigation and settlement costs accrual. It is at least reasonably possible that the estimates will change within the next year. Actual results may also differ materially from management’s estimates.

Change in accounting estimate—There were no changes in accounting estimates during fiscal 2007. During fiscal 2006, the Company revised its estimate of the useful lives of certain production test equipment due to technology changes. Those lives were shortened to 2 years. Previously, all production test equipment was depreciated over 5 years. These changes were made to better reflect the estimated periods during which such equipment will remain in service. The change had the effect of increasing fiscal 2006 depreciation expense which was recorded as cost of revenues and decreasing net income by approximately $130,000 (less than $0.01 per basic and diluted share).

Concentration of Credit Risk—Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments and accounts receivable. The majority of the Company’s cash and cash equivalents and short-term investments are on deposit with two financial institutions. The Company performs ongoing credit evaluations of its customers and generally does not require collateral for sales on credit. The Company reviews accounts receivable on a monthly basis to determine if any receivables will potentially be uncollectible. The Company includes any accounts receivable

F-6

balances that are determined to be uncollectible, along with a general reserve, in its overall allowance for doubtful accounts. The general reserve in the allowance for doubtful accounts is a calculation based upon the accounts receivable balance and the historical effectiveness of the Company’s collection of those receivables. The Company will continue to maintain reserves for potential credit losses.

Cash and Cash Equivalents—The Company considers all highly liquid debt instruments purchased with a remaining maturity of 90 days or less to be cash equivalents.

Short Term Investments—Short-term investments represent highly liquid debt instruments with a remaining maturity date at purchase of greater than 90 days and are stated at fair value. The differences between amortized cost (cost adjusted for amortization of premiums and accretion of discounts which are recognized as adjustments to interest income) and fair value representing unrealized holding gains or losses, are recorded separately as a component of accumulated other comprehensive income (loss) within shareholders’ equity. The Company’s debt securities are classified as available-for-sale because the sale of such securities may be required prior to maturity. Any gains and losses on the sale of debt securities are determined on a specific identification basis.

Inventories—Inventories are stated at the lower of standard cost (which approximates first-in, first-out basis) or market. The Company periodically reviews its inventories for excess and obsolete inventory items and adjusts carrying costs to estimated net realizable values when they are determined to be less than cost. As a result of this inventory review, the Company charged approximately $1.2 million, $29,000 and $230,000 to cost of revenues for fiscal 2007, 2006 and 2005, respectively.

Long-Term Investments—Investments in private equity securities of less than 20% owned companies are accounted for using the cost method unless the Company can exercise significant influence or the investee is economically dependent upon the Company, in which case the equity method is used. The Company evaluates the long-term investments for impairment annually according to Emerging Issues Task Force (“EITF”) Issue No. 03-01, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments. EITF 03-01 provides guidance for evaluating whether an investment is other-than-temporarily impaired and requires certain disclosures with respect to these investments. The guidance also included accounting considerations subsequent to the recognition of an other-than-temporary impairment and requirements for disclosures about unrealized losses that have not been recognized as other-than-temporary impairments.

Equipment and Leasehold Improvements—Equipment and leasehold improvements are stated at cost and categorized into computer and test equipment, software, furniture and fixtures and other. Depreciation and amortization are computed using the straight-line method based on the useful lives of the assets (three to five years) or the lease term if shorter, except for certain production test equipment (two to five years). The contributed leasehold improvements provided by the landlord for the Company’s current facility is amortized using the straight-line method over lesser of the remaining lease term or useful life of leasehold improvements.

Goodwill and Purchased Intangible Assets—Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The amounts and useful lives assigned to intangible assets acquired, other than goodwill, impact the amount and timing of future amortization.

In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 142, “Goodwill and Other Intangible Assets,” the Company reviews goodwill for impairment annually, or more frequently, when events or changes in circumstances indicate that the carrying amount may not be recoverable. The provisions of SFAS 142 require that a two-step test be performed to assess goodwill for impairment. First, the fair value of each reporting unit is compared to its carrying value. If the fair value exceeds the carrying value, goodwill is not impaired and no further testing is performed. The second step is performed if the carrying value exceeds the fair value. The fair

F-7

value of a reporting unit is allocated to all the assets and liabilities of the reporting unit as if the reporting unit had been acquired in a business combination at the date of the impairment test. The fair value of tangible net assets and both recognized and unrecognized intangible assets is deducted from the fair value of the reporting unit to determine the implied fair value of reporting unit goodwill. The implied fair value of the reporting unit’s goodwill must be compared to the carrying value of the goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, an impairment loss equal to the difference will be recorded.

We are currently amortizing acquired intangible assets with definite lives. Acquired developed technology is amortized over 7 years and non-compete agreements are amortized over the contractual period (currently 3 years). The amortization expense for acquired developed technology is classified as cost of sales and the amortization expense for other acquired intangible assets is classified as research and development expense in our consolidated statements of income.

Long Lived Assets—The Company accounts for long-lived assets, including purchased intangible assets, in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. Long-lived assets are evaluated for impairment whenever events or changes in circumstances such as a change in technology indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposal is less than its carrying amount.

Revenue Recognition—We derive revenues primarily from three principal sources: product sales, product development contracts and service contracts. We generally recognize revenues for product sales and service contracts in accordance with Staff Accounting Bulletin (“SAB”) No. 104, “Revenue Recognition”, under which revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or service has been rendered, the fee is fixed or determinable, and collectibility is reasonably assured.

Revenues from product sales to OEMs, distributors and end users are generally recognized upon shipment, as shipping terms are FOB shipping point, except that revenues are deferred when management cannot reasonably estimate the amount of returns or where collectibility is not assured. In those situations, revenue is recognized when collection subsequently becomes probable and returns are estimable (generally upon resale by customers, often referred to as a sell-through basis). Allowances for sales returns, price protection and warranty costs are recorded at the time that revenues are recognized.

Product development agreements typically require that we provide customized software to support customer-specific designs, accordingly this revenue is accounted for under the AICPA Statement of Position (“SOP”) 97-2. We offer post-contract customer support (“PCS”) on a contractual basis for additional fees, which is typically a one year term. In instances where software is bundled with the PCS, vendor specific objective evidence does not exist to allocate the total fee to all undelivered elements of the arrangement and, therefore, revenue and related costs are deferred until all elements, except PCS are delivered. The total fee is then recognized ratably over the PCS term (typically one year) after the software is delivered. We classify development costs related to product development agreements as cost of revenues. Product development revenues were approximately $581,000, $1.2 million and $981,000, for fiscal 2007, 2006, and 2005, respectively.

Revenues from service contracts consist of fees for providing engineering support services, and are recognized ratably over the contract term. Expenses related to support service revenues are included in cost of sales. Support service revenues were $334,000, $150,000 and $303,000 for fiscal 2007, 2006 and 2005 respectively.

Research and Development expenses—Research and Development expenses include costs and expenses associated with the design and development of new products. To the extent that such costs include the development of computer software, they are generally incurred prior to the establishment of the technological feasibility of the related product that is under development and are therefore expensed as incurred.

F-8

Income Taxes—Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (b) operating losses and tax credit carryforwards. Income taxes are accounted for under an asset and liability approach in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 109. Deferred tax liabilities are recognized for future taxable amounts and deferred tax assets are recognized for future deductions net of a valuation allowance to reduce deferred tax assets to amounts that are more likely than not to be realized.

Stock-Based Compensation—On January 29, 2006, the Company adopted SFAS No. 123 (revised 2004), “Share-Based Payment,” (“123(R)”) which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors based on estimated fair values. SFAS 123(R) supersedes our previous accounting under Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”) for periods beginning in fiscal 2007. In March 2005, the Securities and Exchange Commission issued SAB No. 107 relating to SFAS 123(R). We have applied the provisions of SAB 107 in our adoption of SFAS 123(R).

We adopted SFAS 123(R) using the modified prospective transition method, which requires the application of the accounting standard as of January 29, 2006, the first day of our fiscal year 2007. Our consolidated financial statements as of and for the twelve months ended February 3, 2007 reflect the impact of SFAS 123(R). In accordance with the modified prospective transition method, our consolidated financial statements for prior periods have not been restated to reflect, and do not include, the impact of SFAS 123(R). Stock-based compensation expense recognized under SFAS 123(R) for fiscal 2007 was $4.9 million, which consisted of stock-based compensation expense related to the grant of stock options and stock purchase rights.

SFAS 123(R) requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service period in our consolidated statement of operations. Prior to the adoption of SFAS 123(R), we accounted for employee equity awards and employee stock purchases using the intrinsic value method in accordance with APB 25 as allowed under SFAS No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”).

Stock-based compensation expense recognized during fiscal 2007 is based on the value of the portion of share-based payment awards that is ultimately expected to vest during the period. Stock-based compensation expense recognized in our consolidated statement of operations for fiscal 2007 includes compensation expense for share-based payment awards granted prior to, but not yet vested as of January 28, 2006 based on the grant date fair value estimated in accordance with the pro forma provisions of SFAS 123 and compensation expense for the share-based payment awards granted subsequent to January 28, 2006 based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R). As stock-based compensation expense recognized in the consolidated statement of operations for fiscal 2007 is based on awards ultimately expected to vest, it has been adjusted for estimated forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In our pro forma information required under SFAS 123 for the periods prior to fiscal 2007, the Company accounted for forfeitures as they occurred.

F-9

The effect of recording stock-based compensation to employees for the fiscal year ended February 3, 2007 was as follows (in thousands, except per share amount):

	Fiscal 2007
Stock-based compensation by type of award:
Stock options	$	4,842
Employee stock purchase plan		107
Total stock-based compensation		4,949
Tax effect on stock-based compensation		(317	)
Net effect on net income		4,632
Effect on net income per share:
Basic	$	0.20
Diluted	$	0.18

During fiscal 2007, we recorded stock-based compensation of $317,000 for consulting services. The net expense recorded after tax effect was $296,000 or $0.01 per basic and diluted share.

Prior to the Adoption of SFAS 123(R)

Prior to the adoption of SFAS 123(R), we provided the disclosures required under SFAS 123, as amended by SFAS No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosures.” Consistent with the disclosure provisions of SFAS 148, our net loss and basic and diluted loss per share for fiscal 2006 and 2005 would have been adjusted to the pro forma amounts indicated below (in thousands, except per share amounts):

current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these items.

Recent Accounting Pronouncements

In June 2006, the Financial Accounting Standards Board (“FASB”) issued FASB interpretation No. 48 (FIN No. 48) “Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109 (FAS No. 109).” This interpretation prescribes a recognition threshold and measurement attribute for tax positions taken or expected to be taken in a tax return. This interpretation also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The evaluation of a tax position in accordance with this interpretation is a two-step process. In the first step, recognition, the Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step addresses measurement of a tax position that meets the more-likely-than-not criteria. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in a) an increase in a liability for income taxes payable or a reduction of an income tax refund receivable, b) a reduction in a deferred tax asset or an increase in a deferred tax liability or c) both a and b. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be de-recognized in the first subsequent financial reporting period in which that threshold is no longer met. Use of a valuation allowance as described in FAS No. 109 is not an appropriate substitute for the de-recognition of a tax position. The requirement to assess the need for a valuation allowance for deferred tax assets based on sufficiency of future taxable income is unchanged by this interpretation. This interpretation is effective for the Company on February 4, 2007. The Company is currently evaluating the impact FIN No. 48 will have to the Company’s consolidated balance sheet and statement of operations.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157,Fair Value Measurements (“SFAS 157”). SFAS 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements. The changes to current practice resulting from the application of SFAS 157 relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and is required to be adopted by the Company beginning in the first quarter of fiscal 2009. We are currently in the process of evaluating the impact that the adoption of SFAS 157 will have on our consolidated financial position and results of operation.

2. RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS

Restatement of Previously Issued Financial Statements

The Company is restating its consolidated balance sheet as of January 28, 2006 and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the Company’s fiscal years ended January 28, 2006 and January 29, 2005 as a result of an internal stock option investigation commenced by the Audit Committee of the Company’s Board of Directors (“Board”) and other errors identified as a result of the audit of the fiscal year ended February 3, 2007, and the re-audit of fiscal years ended January 28, 2006 and January 29, 2005. In addition, the Company is restating the unaudited quarterly financial information and financial statements for the interim periods of 2006, and unaudited condensed financial statements for the three months ended April 29, 2006.

Financial information included in the reports on Form 10-K, Form 10-Q and Form 8-K filed by the Company prior to September 21, 2006, and the related opinions of the independent registered public accounting

F-11

firms, and all earnings press releases and similar communications issued by the Company prior to September 21, 2006 should not be relied upon and are superseded in their entirety by this 2007 Form 10-K and other reports on Form 10-Q and Form 8-K filed by the Company with the Securities and Exchange Commission on or after September 21, 2006.

Background-Stock Option Investigation

We previously disclosed, on July 26, 2006, that the Audit Committee of our Board had commenced an internal investigation, assisted by outside legal counsel and accounting experts, of our practices related to historical stock option grants. During the investigation, the Audit Committee reviewed stock option grants to officers, directors and employees from 1997 to 2006 encompassing approximately 1,000 grants on 41 different grant dates. On September 21, 2006, we announced that certain of the actual measurement dates for prior option grants may differ from the recorded measurement dates.

The Audit Committee concluded its investigation in April 2007. Its investigation found that nearly all of the stock option grants for new hires, as well as for promotion and retention, were approved by the use of Unanimous Written Consents (“UWC” or “UWCs”) of the Company’s Board, rather than at a Board meeting. The Audit Committee found that the Company’s process resulted in grant dates on the UWCs routinely established before the receipt of fully-signed UWCs authorizing such grants. The Audit Committee also found that due to these and other deficiencies in the administration of our stock option plans, a number of options grants between 1997 and 2006 were misdated.

The Audit Committee has concluded that the stock option grant process, including the utilization of UWC process described above, reflected management’s lack of appreciation of the legal and accounting standards of the stock option grant process and the erroneous belief that dates other than the stated grant date were, at best, administrative in nature and not governing. Based on the quarterly low price points of the option grants, and absent any objective documentation to the contrary, the Audit Committee has also speculated that the ultimate selection of the grant dates stated on the UWCs may have benefited from limited hindsight, but it has not found any conclusive evidence to this effect. The Audit Committee did not find any evidence of intent to deceive or to destroy or alter documents or to obstruct or impede the investigation in any way.

Accounting Considerations—Stock-Based Compensation

We originally accounted for all employee, officer and director stock option grants as fixed grants under APB 25, using a measurement date of the recorded grant date. We issued all grants with an exercise price equal to the fair market value of our common stock on the recorded grant date, and therefore originally recorded no stock-based compensation expense.

As a result of the findings of the investigation conducted by the Audit Committee and our own further review of our stock option granting practices, we determined that, although fixed accounting under APB 25 was appropriate, the measurement dates for certain stock option grants differed from the recorded grant dates for such grants. In some instances, we were only able to locate sufficient evidence to identify the measurement date described in APB 25, the first date on which both the number of shares that an individual employee was entitled to receive and the exercise price were known, within a range of possible dates. As a result, we developed a methodology to establish the revised measurement date as our estimate of the first date on which both the number of shares that an individual employee was entitled to receive and the exercise price were known with finality. Using the methodology described below, we concluded that it was appropriate to revise the measurement dates for these grants based upon our findings, and we refer to these revised measurement dates as the “Deemed Measurement Dates”.

We calculated stock-based compensation expense under APB 25 based upon the intrinsic value as of the Deemed Measurement Dates of stock option awards determined to be “fixed” under APB 25 and the vesting

F-12

provisions of the underlying options. We calculated the intrinsic value on the Deemed Measurement Date as the closing price of our common stock on such date as reported on the Nasdaq National Market, now the Nasdaq Global Market, less the exercise price per share of common stock as stated in the underlying stock option agreement, multiplied by the number of shares subject to such stock option award. We recognized these amounts as compensation expense over the vesting period of the underlying options (generally four years).

The methodology developed by such advisor was used by us, with such advisor’s assistance, to determine the Deemed Measurement Dates associated with prior stock option grants was as follows:

New Hire Non-Officer Employee Stock Options Effective January 2006—Effective January 2006, we amended our practice of granting options to new hire non-officer employees to grant all such options at the end of the quarter in which the employee was hired. Accordingly, we determined the Deemed Measurement Date for each of these grants to be the last business day of the quarter of the employee’s quarter of hire, because it was determined to be the first date when the number of shares and the price of each grant were known with finality.

All Other Stock Options—We determined the Deemed Measurement Dates for all stock option grants other than those described above to be either the Approval Date or the Communication Date for the stock option grant. The Approval Date was used in each case that it was reliably determined, and the Communication Date was used in those cases where the Approval Date could not be determined or was determined to be unreliable.

The “Approval Date” for the stock option was the date set forth in executed minutes or a fully-executed consent of the board of directors or stock option committee, provided that (1) documentary evidence existed that the allocation of shares had been finalized on such date, and (2) the Communication Date for the stock option was within 30 days of the Approval Date.

The “Communication Date” for the stock option was the date we determined the key terms of the option (both the number of shares and the exercise price) to be initially communicated to the optionee. In the absence of specific documentary evidence of initial communication, we generally determined the Communication Date to be the earliest of: (1) the date the employee record was added to the stock option database application (the “Record Add Date”); (2) the optionee manual signature date on the stock option agreement (the “Stock Option Agreement Date”); and (3) for officers and directors, the date that a Form 3 or 4 was filed with the SEC with respect to the grant (the “Form 3/4 Date”). However, if we determined that the earliest date was the Record Add Date, and if the Stock Option Agreement Date was more than 30 days after the Record Add Date, then we determined the Communication Date to be the earlier of the Stock Option Agreement Date or the Form 3/4 Date.

When applying this methodology to groups of grants, we generally determined the Communication Date for the group to be the latest Record Add Date, the earliest Stock Option Agreement Date, as we determined that, under our stock option grant process, the terms of stock options were generally communicated concurrently to each member of the group. We excluded a limited number of options, or “Outliers”, from the determination of the latest Record Add Date and the earliest Stock Option Agreement Date for a group of grants when, based upon available evidence, we considered the Outlier dates as not reliable as to the date that the terms of the stock option grants were communicated to the group.

We determined that variable accounting under APB 25, which is required in situations when the terms of option grants are modified subsequent to the date that all granting actions are complete, was not applicable for any of the grants during the Review Period.

The methodology described above, and the determination of which stock option grants should be considered Outliers, as described above, involves judgment. We believe that the judgments applied are consistent with the provisions of the appropriate accounting pronouncements and the letter from the Office of the Chief Accountant of the SEC to the Financial Executives International and the American Institute of Certified Public Accountants dated September 19, 2006.

Restatement Adjustments

Our restated consolidated financial statements contained in this 2007 Form 10-K incorporate stock-based compensation expense, but excludes related payroll taxes, penalties and interest expenses. The restatement adjustments result in a $16.4 million increase in accumulated deficit as of January 28, 2006. This amount includes a reduction of our previously reported consolidated net income of approximately $3.4 million and $2.0 million for the years ended January 28, 2006 and January 29, 2005, respectively. The total restatement impact for periods through January 31, 2004 of $10.2 million has been reflected as a prior period adjustment to accumulated deficit as of that date.

The restatement adjustments reduced the Company’s previously reported diluted earnings per share by $0.15 and $0.09 for the years ended January 28, 2006 and January 29, 2005, respectively.

F-14

Stock-Based Compensation—These adjustments are from the Company’s determination that the initially recorded measurement dates of option grants could not be relied upon, based upon the Audit Committee’s investigation and the Company’s subsequent reviews and analyses. For substantially all such option grants, there was correspondence or other evidence that indicated that not all required corporate approvals had been obtained as of the initially recorded measurement date. The Company adopted a methodology to remeasure these option grants to a revised measurement date, as described below, and accounted for these grants as fixed awards under Accounting Principles Board Opinion (APB) No. 25Accounting for Stock Issued to Employees, or APB 25.

Accelerated vesting and extended exercisability—These adjustments were made as a result of the acceleration of stock option vesting upon termination and the extension of the exercisability of certain options held by a few employees.

Payroll taxes, interest and penalties—In connection with the stock-based compensation adjustments, the Company determined that certain options previously classified as Incentive Stock Options under the U.S. Internal Revenue Code (“IRC”), or ISOs, were determined to have been granted with an exercise price below the fair market value of our stock on the revised measurement date (see discussion under “Accounting Considerations” below). Under IRC tax regulations, ISOs may not be granted with an exercise price less than the fair market value on the date of grant, and therefore these grants might not qualify for ISO tax treatment. These stock options are referred to as the “Affected ISOs.” The potential disqualification of ISO status exposes the Company to additional payroll-related withholding taxes on the exercise of options granted to U.S. employees, and penalties and interest for failing to properly withhold taxes on exercise of those options. As of February 3, 2007, the Company has recorded a net liability of approximately $3.9 million in connection with the potential disqualification of ISO tax treatment for option awards. The payroll tax, interest and penalty expenses were recorded in the periods in which the underlying stock options were exercised. Then, in subsequent periods in which the liabilities were legally extinguished due to expiration of statutes of limitations, the expenses were reversed, and recognized as a reduction in the related functional expense category in the Company’s consolidated statements of operations.

Because virtually all holders of options issued by the management of the Company were not involved in or aware of the incorrect pricing of the Affected ISOs, management has taken certain actions and is considering possible additional actions to address the impact of certain adverse tax consequences, including under IRC Section 409A, that may result from the exercise price of stock options being less than the fair market value of the Company’s common stock on the Deemed Measurement Date, as defined below. IRC Section 409A (and, as applicable, similar tax laws in California and other states) imposes penalty taxes on our employees on stock options granted with an exercise price lower than the fair market value on the date of grant that vest after December 31, 2004 (the “409A Affected Options”). The Internal Revenue Service (“IRS”) has issued transition rules under IRC Section 409A that allows for a correction, or cure, for 409A Affected Options. In December 2006, the Company entered into agreements with each of its executive officers to amend the 409A Affected Options held by such person to limit the period of exercisability to a defined calendar year. Further, prior to December 31, 2007, the Company may offer other holders of 409A Affected Options the opportunity to effect a cure of all such options by either increasing the exercise price to the market price on the actual grant date or, if lower, the market price at the time of the amendment or limiting the period of exercisability to a defined calendar year. The Company may approve bonuses payable to holders of the amended options to compensate them for the resulting increase in their option exercise price. The amount of these bonuses would be effectively repaid to the Company if and when the options are exercised and the increased exercise price is paid (although there is no assurance that the options will be exercised). If necessary to comply with applicable law, such cure will be effected as a tender offer. In connection with such cure, the Company may pay approximately $2.5 million in 2008 to non-officer employees of the Company. For those employees who exercised a 409A Affected Option during 2006, as a precautionary measure, we have sent the IRS and California Franchise Tax Board (“FTB”) notices of our intent to participate in settlement programs they have developed to allow employers to pay certain taxes on behalf of employees to settle potential taxes resulting from the exercise of these 409A Affected Options during 2006. In connection with the Company’s proposed participation in these programs, the Company may pay

F-15

an aggregate of approximately $0.3 million to the IRS and FTB. The Company may also approve bonuses of an aggregate of approximately $0.2 million payable to these effected employees to compensate them for additional income tax imposed on them as a result of the payments the Company may make on their behalf to the IRS and FTB.

Income tax benefit (provision)—Because of the potential impact of the measurement date changes on the qualified status of Affected ISOs, the Company has determined that all Affected ISOs might not be qualified as ISOs under IRS regulations, and therefore should be accounted for as if they were Nonstatutory Stock Options under the IRC, or NSOs, for income tax accounting purposes. However, the Company recorded no income tax benefit associated with stock-based compensation and related charges because of valuation allowances provided against the resulting deferred tax assets, as the Company believes that sufficient doubt exists that it will be able to realize the value of those assets.

Other Accounting Adjustments

In addition to the stock-based compensation adjustments described above, we also made certain other adjustments to our previously-reported net income (loss):

• During our fiscal 2007 audit, we determined that incorrect measurement dates were used to value stock options exchanged with the employees previously with Blue7 employees upon the acquisition. As a result, the increase in purchase price of $0.7 million was recorded as an increase to both goodwill and future stock-based compensation expense as of the date of acquisition. This compensation expense will be amortized to our consolidated statement of operations over the remaining vesting period of the related options. For the first quarter of fiscal 2007, we recorded incremental stock-based compensation expense of $40,000.

• During our fiscal 2007 audit, we determined that the collection of our French research and development tax credit was reasonably assured and, therefore, should have been accounted for using the accrual method, whereas such credits were previously recorded upon the receipt of cash. As a result, we restated our previously-reported operating results for fiscal years 2001 through 2006 to record aggregate income of $217,000 in Interest and other income.

• For fiscal 2005 and prior years we accrued and expensed estimated audit and tax professional fees ratably during the fiscal year prior to such services being actually performed. As a result, we restated fiscal years 2003 through 2006 to reflect the expensing of such audit and tax professional fees as the services were performed. The restatement for this element resulted in increases (decreases) in General and administrative expenses of zero, $224,000, and $(105,000) for each of fiscal year 2007, 2006, and 2005, respectively.

• During our fiscal 2007 audit, we restated our previously-reported operating results for fiscal years 2001 through 2006 to record certain adjustments to previously-provided income taxes. These adjustments amounted to an aggregate increase in income tax provision and income taxes payable of $326,000 to reflect income taxes related to our foreign subsidiaries.

• During our fiscal 2007 audit, we restated our previously-reported operating results for the first quarter of fiscal 2007 to record an increase to our warranty reserve and warranty expense of $27,000.

In addition to the above adjustments, reclassifications have been made to prior year balances to conform to the current year presentation.

10. COMMITMENTS AND CONTINGENCIES

The Company’s standard terms and conditions of sale include a patent infringement indemnification provision for claims from third parties related to the Company’s intellectual property. The terms and conditions of sale generally limit the scope of the available remedies to a variety of industry-standard methods including, but not limited to, a right to control the defense or settlement of any claim, procure the right for continued usage, and a right to replace or modify the infringing products to make them non-infringing. Such indemnification provisions are accounted for in accordance with SFAS No. 5 Accounting for Contingencies. To date, the Company has not incurred or accrued any costs related to any claims under such indemnification provisions.

Leases—The Company’s primary facilities are leased under a non-cancelable lease which expires in September 2007.

The Company currently places non-cancelable orders to purchase semiconductor products from its suppliers on an eight to twelve week lead-time basis. As of February 3, 2007, the total amount of outstanding non-cancelable purchase orders was approximately $4.6 million.

Royalties—The Company pays royalties for the right to sell certain products under various license agreements. During fiscal 2007, 2006 and 2005, the Company recorded royalty expense of $1.3 million, $490,000 and $270,000, respectively.

Benefit Plan—The Company sponsors a 401(k) savings plan in which most employees are eligible to participate. The plan commenced in fiscal 1994. The Company is not obligated to make contributions to the plan and no contributions have been made by the Company.

Legal Proceedings—

Certain current and former directors and officers of the Company have been named as defendants in several shareholder derivative actions filed in the United States District Court for the Northern District of California, which have been consolidated under the caption In re Sigma Designs, Inc. Derivative Litigation (the “Federal Action”) and in a substantially similar shareholder derivative action filed in the Superior Court for Santa Clara County, California captionedKorsinsky v. Tran, et al. (the “State Action”).

Plaintiffs in the Federal and State Actions allege that the individual defendants breached their fiduciary duties to the Company in connection with the alleged backdating of stock option grants during the period from 1994 through 2005 and that certain defendants were unjustly enriched. Plaintiffs in the Federal Action assert derivative claims against the individual defendants based on alleged violations of Sections 10(b), 14(a) and 20(a) of the Securities Exchange Act of 1934, and Rules 10b-5 and 14a-9 promulgated thereunder. They also allege

F-22

that the individual defendants aided and abetted one another’s alleged breaches of fiduciary duty and violated California Corporations Code section 25402 and bring claims for an accounting and rescission. In the State Action, plaintiffs also allege that the individual defendants wasted corporate assets. Both Actions seek to recover unspecified money damages, disgorgement of profits and benefits and equitable relief. The Federal Action also seeks treble damages, rescission of certain defendants’ option contracts, imposition of a constructive trust over executory option contracts and attorney’s fees. The Company is named as a nominal defendant in both the Federal and State Actions; thus, no recovery against the Company is sought.

The Company has filed a motion to dismiss the Federal Action on the ground that the plaintiffs had not made a pre-litigation demand on the Company’s Board of Directors and had not demonstrated that such a demand would have been futile. The defendant directors and officers joined in that motion, and filed a motion to dismiss the Federal Action for failure to state a claim against each of them. The Company has also filed a motion to dismiss or stay the State Action in favor of the earlier-filed Federal Action. The defendant directors and officers joined in that motion. Pursuant to a joint stipulation, the court ordered that the State Action be stayed in favor of the earlier-filed Federal Action.

The Company has previously disclosed in press releases that the Securities and Exchange Commission (“SEC”) has initiated an informal inquiry into the Company’s stock option granting practices. The SEC has requested that the Company voluntarily produce documents relating to, among other things, our stock option practices. The Company is cooperating with the SEC.

11. CURRENT AND LONG-TERM DEBT

On August 12, 2005, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with United Commercial Bank (the “Bank”). The Loan Agreement provides for a maximum borrowing amount of approximately $15.5 million across three credit facilities consisting of two 2-year Lines of Credit and a 36-month Term Loan of $500,000.

The first 2-year Line of Credit allows the Company to borrow up to 80% of its accounts receivable to a maximum of $15 million and, has a floating interest rate of the Wall Street Journal Prime Rate plus 0.25% per annum. The second 2-year Line of Credit allows the Company to borrow up to $5 million as long as (1) unrestricted cash at the Bank exceeds $10 million, (2) the credit limit of the first 2-year Line of Credit is utilized and (3) the total outstanding balances under both 2-year Lines of Credit cannot exceed $15 million at any one time. The second 2-year Line of Credit has a floating interest rate of the Wall Street Journal Prime Rate plus 0.25% per annum. The Company’s obligations under the Loan Agreement are secured by substantially all of the Company’s assets, including its intellectual property. Both Lines of Credit expire and are payable in full on August 12, 2007. At the Company’s option, the loans under the Loan Agreement can be repaid without premium or penalty. As of February 3, 2007, the Company had no amounts outstanding under these two Lines of Credit but had availability to draw down approximately $8.5 million. On February 8, 2006, the Company utilized $2.4 million of the first 2-year Line of Credit for a standby letter of credit to a supplier.

Principal amounts under the Term Loan will become due and payable on a monthly basis such that the Term Loan will be fully repaid in February 2008. The monthly payment including interest of the Term Loan is approximately $18,000. The Term Loan has a floating interest rate of the Wall Street Journal Prime Rate plus 0.5% per annum. The effective average interest rate paid on the Term Loan from January 29, 2006 to February 3, 2007, was approximately 8.54%. As of February 3, 2007, the Company had $241,000 outstanding under the Term Loan. The amounts of the Term Loan mature as follows (in thousands):

Maturities	Loan Payment
Fiscal 2008	$	226

Under the Loan Agreement, the Company is subject to certain financial covenants. As of February 3, 2007, the Company was not in compliance with all of the covenants contained in the Loan Agreement, and is seeking a waiver from the lender.

12. NET INCOME (LOSS) PER SHARE

Basic earnings per share (EPS) excludes dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock.

The reconciliation of the denominators of the basic and diluted net income per share computations for the fiscal years 2007, 2006 and 2005 is shown in the following table (in thousands, except per share data):

Stock Option Plans

2003 Director Stock Option Plan (the “2003 Director Plan”): During fiscal 2004, the Company adopted the 2003 Director Stock Option Plan to replace the predecessor 1994 Director Stock Option Plan which expired in fiscal 2005. A total of 207,500 shares of common stock are currently reserved for issuance under the 2003 Director Plan of which 65,000 have been granted as of February 3, 2007.

2001 Employee Stock Option Plan (the “2001 Option Plan”): During fiscal 2002, the Company adopted the 2001 Employee Stock Option Plan (the “2001 Option Plan”) and reserved 500,000 shares of the Company’s common stock for issuance under the plan, with automatic annual increases on the first day of the Company’s fiscal year equal to the lesser of (i) 1,000,000 shares, (ii) 4% of the Company’s outstanding common stock on such date or (iii) a lesser number of shares as determined by the Board of Directors, commencing February 1, 2002. On March 8, 2006, an additional 877,834 shares resulting from the automatic annual increase of 4% of the Company’s outstanding common stock were added to the shares available for issuance under the 2001 Employee Stock Option Plan. As of February 3, 2007, the Company reserved a total of 3.8 million shares of common stock for issuance under this plan. Generally, the plan provides for the granting of options to purchase shares of common stock at the fair market value on the date of grant. Options granted under the plan become exercisable over a five-year period and expire no more than ten years from the date of grant (all options outstanding at February 3, 2007 expire ten years from date of grant). The 2001 plan replaced the predecessor 1994 Option Plan which expired in fiscal 2005.

As of February 3, 2007, the unrecorded stock-based compensation balance related to stock options outstanding excluding estimated forfeitures was $12.3 million and will be recognized over an estimated weighted average amortization period of 2.70 years. The amortization period is based on the expected vesting term of the option.

Preferred Stock Rights Plan

On May 28, 2004, the Company’s Board of Directors adopted a Preferred Stock Rights Plan. Under the plan, the Company declared a dividend of one Preferred Share Purchase Right (“the Rights”) for each share of Common Share held by stockholders of record as of the close of business on June 18, 2004. Each Right initially entitles stockholders to purchase a fractional share of the Company’s Preferred Stock at $58 per share. However, the rights are not immediately exercisable and will become exercisable only upon the occurrence of certain events. If a person or group acquires or announces a tender or exchange offer that would result in the acquisition of 15 percent or more of the Company’s common stock while the stockholder rights plan remains in place, then, unless the rights are redeemed by the Company for $0.001 per right, the rights will become exercisable by all rights holders except the acquiring person or group for shares of the Company or the third party acquirer having a value of twice the right’s then-current exercise price. Absent of the aforementioned triggering events, the Rights will expire on June 18, 2014. The rights may have the effect of deterring or delaying a change in control of the Company.

Employee Stock Purchase Plan

During fiscal 2002, the Company adopted the 2001 Employee Stock Purchase Plan (the “2001” Purchase Plan”) and reserved 100,000 shares of the Company’s common stock for issuance under the plan, with an automatic annual increase on the first day of the Company’s fiscal year equal to the lesser of (i) 500,000 shares, (ii) 2% of the Company’s outstanding common stock on such date or (iii) a lesser number of shares as determined by the Board of Directors. On February 1, 2005, the Board of Directors approved an additional 25,000 shares to be reserved under the 2001 Purchase Plan. Under this plan, eligible employees may authorize payroll deductions of up to 10% of their regular base salaries to purchase common stock at 85% of the fair market value at the beginning or end of each six-month offering period. During fiscal 2007, 2006 and 2005, 36,277, 81,569 and 66,798 shares of the Company’s common stock were purchased at an average price of $8.02, $6.59 and $6.58 per share, respectively. At February��3, 2007, 226,292 shares under the 2001 Purchase Plan remain available for future purchase.

Stock-Based Compensation

Valuation Assumptions

The fair value of share-based compensation awards is estimated at the grant date using the Black-Scholes option valuation model. The determination of fair value of share-based compensation awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, our expected stock price volatility over the term of the awards, and actual employee stock option exercise behavior.

In connection with the adoption of SFAS 123(R), we reassessed our valuation technique and related assumptions. We estimate the fair value of stock options using a Black-Scholes valuation model, consistent with the provisions of SFAS 123(R), SAB No. 107 and our prior period pro forma disclosures of net earnings, including stock-based compensation expense (determined under a fair value method as prescribed by SFAS 123). The weighted-average estimated values of employee stock options granted during fiscal 2007, 2006, and 2005 were $9.58, $6.22, and $5.02 per share, respectively. The weighted-average estimated fair value of employee stock purchase rights granted pursuant to the ESPP during fiscal 2007 was $5.93, per share, respectively. The fair

F-27

value of each option and employee stock purchase right grant is estimated on the date of grant using the Black-Scholes option valuation model with the following weighted-average assumptions:

	Years Ended
	February 3, 2007		January 28, 2006		January 31, 2005
			(As Restated) (1)		(As Restated) (1)
Stock Options
Expected volatility	69.98	%	61.10	%	75.57	%
Risk free interest rate	4.77	%	4.29	%	2.61	%
Expected term of options and purchase rights (in years)	5.90		1.43		1.41
Dividend yield	None		None		None
Employee Stock Purchase Plan
Expected volatility	54.55	%	62.10	%	67.68	%
Risk free interest rate	4.66	%	3.10	%	1.37	%
Expected term of options and purchase rights (in years)	0.50		0.50		0.50
Dividend yield	None		None		None

The computation of the expected volatility assumptions used in the Black-Scholes calculations for new grants and purchase rights is based on the historical volatility of our stock price, measured over a period equal to the expected term of the grant or purchase right. The risk-free interest rate is based on the yield available on U.S. Treasury Strips with an equivalent remaining term. The expected life of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards and vesting schedules. The expected life of purchase is the period of time remaining in the current offering period. The dividend yield assumption is based on our history of not paying dividends and assumption of not paying dividends in the future.

As the stock-based compensation expense recognized in the consolidated statement of operations for fiscal 2007 is based on awards ultimately expected to vest, such amount has been reduced for estimated forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on our historical experience. Prior to fiscal 2007, the expected forfeitures of employee stock options were accounted for on an as-incurred basis.

At February 3, 2007, undistributed earnings of the Company’s French operations totaling $2.7 million were considered to be permanently reinvested. No deferred tax liability has been recognized for the remittance of such earnings to the U.S. since it is management’s intention to utilize those earnings in the foreign operations. Generally, such earnings become subject to U.S. tax upon the remittance of dividends and under certain other circumstances. It is not practicable to estimate the amount of deferred tax liability on such undistributed earnings.

We have elected to track the portion of our federal and state net operating loss carryforwards attributable to stock option benefits, in a separate memo account pursuant to SFAS No. 123(R). Therefore, these amounts are no longer included in our gross or net deferred tax assets. Pursuant to SFAS No. 123(R), footnote 82, the benefit of these net operating loss carryforwards will only be recorded to equity when they reduce cash taxes payable. The amounts removed to the memo account as of 2/3/2007 are $5.8 million for federal and $0.3 million for state tax purposes, respectively.

F-29

On November 10, 2005, the Financial Accounting Standards Board (FASB) issued FASB Staff Position No. FAS 123(R)-3 “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards.” The Company has elected to adopt the alternative transition method provided in the FASB Staff Position for calculating the tax effects of stock-based compensation pursuant to SFAS 123(R). The alternative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool (“APIC pool”) related to the tax effects of employee stock-based compensation and to determine the subsequent impact on the APIC pool and Consolidated Statements of Cash Flows of the tax effects of employee stock-based compensation awards that are outstanding upon adoption of SFAS 123(R).

SFAS No. 109 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period. Because of the Company’s recent history of operating losses, risks associated with its new product introduction including the dependence on rapid acceptance of new technology, the dependence on development of complimentary software by third parties and other risks, such as technological change in the industry, short product life cycles and reliance on a limited number of suppliers and manufacturing contractors, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a full valuation allowance.

Net operating losses and tax credit carry forwards as of February 3, 2007 are as follows (in thousands):

	Amount		Expiration Years
Net operating losses, federal	$	56,284	Thru 2024
Net operating losses, state		4,525	Thru 2014
Tax credits, federal		7,408	Thru 2027
Tax credits, state		3,266	Thru 2014- Indefinite
Tax credits, foreign		54	Indefinite

Current federal and California tax laws include substantial restrictions on the utilization of net operating losses and tax credits in the event of an “ownership change” of a corporation. Accordingly, the Company’s ability to utilize net operating loss and tax credit carryforwards may be limited as a result of such ownership changes. Such a limitation could result in the expiration of carryforwards before they are utilized.

The effective tax rate of the Company’s provision (benefit) for income taxes differs from the federal statutory rate as follows (in thousands):

15. ACQUISITION

On February 16, 2006, we completed the acquisition of Blue7 for $11.9 million. Blue7’s results of operations are included in statement of operations from the acquisition date. Prior to the acquisition, Sigma held

F-30

approximately 17% of the outstanding shares of Blue7 and provided loans totaling $900,000 to Blue7. Blue7 focuses on the development of advanced wireless technologies and Ultra-Wideband (UWB) semiconductor products. The transaction was accounted for using the purchase method of accounting in accordance with SFAS No. 141, “Business Combinations.”

Assets acquired and liabilities assumed were recorded at their fair values as of February 16, 2006. The total $11.9 million purchase price is comprised of the following (in thousands):

Value of Sigma stock issued	$	8,190
Fair value of vested stock options assumed		1,091
Retirement of note receivables		400
Retirement of interest receivable		25
Investment in Blue7 prior to the acquisition		1,000
Note receivable converted to Blue7 preferred shares prior to the acquisition		500
Cash acquired from Blue7 acquisition		(147	)
Direct costs		804
Total estimated purchase price	$	11,863

As a result of the acquisition, we issued approximately 583,870 shares of Sigma common stock based on an exchange ratio of 0.0529101 shares of Sigma common stock for each outstanding share of Blue7 common stock. Of the 583,870 shares of Sigma common stock issued, 98,470 shares were held in escrow until March, 2007 to satisfy any obligations of Blue7 to indemnify Sigma against any claims against Blue7 for any breaches of its representations or warranties contained in or made pursuant to the merger agreement and certain other matters set forth in the Merger Agreement. The common stock issued in the acquisition was valued at $14.03 which was the average closing sales prices of Sigma common stock for five consecutive trading days from December 13, 2005 to December 19, 2005 surrounding the announcement date (December 15, 2005) of the proposed transaction.

Under the terms of the merger agreement, each Blue7 stock option that was outstanding and unexercised was converted into an option to purchase Sigma common stock based on the 0.0529101 exchange ratio and we assumed those stock options in accordance with the terms of the applicable Blue7 stock option plan and related stock option agreements. Based on Blue7’s stock options outstanding at February 16, 2006, we converted options to purchase approximately 4.8 million shares of Blue7 common stock into options to purchase approximately 231,137 shares of Sigma common stock. The fair value of options assumed was determined using the Black-Scholes valuation model and the following assumptions:

Expected term (in years)	5.13 years
Volatility	74	%
Risk free interest rate	4.59	%

Direct costs of $804,000 include mainly legal and accounting fees, business valuation, and other external costs directly related to the acquisition.

Purchase Price Allocation:

In accordance with SFAS No. 141 the total purchase price was allocated to Blue7’s net tangible and intangible assets based upon their estimated fair values as of February 16, 2006. The excess purchase price over the value of the net tangible and identifiable intangible assets was recorded as goodwill. The fair values assigned to tangible and intangible assets acquired and liabilities assumed are based on estimates and assumptions of management.

F-31

The following represents the allocation of the purchase price to the acquired net assets of Sigma and the associated estimated useful lives:

	Amount		Estimated Useful Life
	(in thousands)
Net tangible assets	$	104
Identifiable intangible assets:
Licensing agreements		39	6 to 15 months
Developed technology		5,300	7 years
Noncompete agreements		1,400	3 years
Goodwill		5,020
Total purchase price	$	11,863

Identifiable intangible assets—Developed technology consists of products that have reached technological feasibility and includes products in the acquired product lines. Developed technology was valued using the discounted cash flow (“DCF”) method. This method calculates the value of the intangible asset as being the present value of the after tax cash flows potentially attributable to it, net of the return on fair value attributable to tangible and other intangible assets.

The results of operations of Blue7 have been included in the Company’s consolidated financial statements subsequent to the date of acquisition. The financial information in the table below summarizes the reported results of operations, as well as the pro forma combined results of operations of the Company and Blue7 as though the companies had been combined as of the beginning of the year presented (in thousands, except per share amounts):

17. RELATED PARTY TRANSACTIONS

On April 10, 2006, the Company entered into a sublease agreement to rent approximately 2,500 square feet of a facility from a start-up company founded by a member of the Company’s board of directors. This is a month-to-month operating lease with base rent of $4,000 plus proportionate share of operating costs commencing April 1, 2006.

During June 2005, the Company loaned $500,000 to Blue7, a California corporation, in which the Company had invested $1.0 million, for an approximately 17% ownership interest. One of the Company’s board members had invested $100,000 for a 2% ownership interest during fiscal 2005. In November 2005 and January 2006, the Company loaned an additional $250,000 and $150,000 to Blue7. As of January 28, 2006, the total outstanding loan balance was $900,000. As of February 3, 2007, the total loan balance of $900,000 was forgiven and accounted as part of the Blue7 acquisition cost.

The Company had an ownership interest of less than 10% in an original equipment manufacturer (the “OEM”) headquartered in Europe which was accounted for using the cost method. The Company sold its ownership interest with a carrying cost of $2.0 million in this OEM for approximately $3.5 million in September 2005, resulting a gain on sale of investment of approximately $1.5 million. During fiscal 2006 and 2005, the Company had product revenues of $123,000 and $4.5 million, respectively, from this OEM.

The Company maintains an investment in Envivio, Inc., (see Note 6) in which the Company has current invested capital of $263,000 for an ownership fraction of less than 1% ownership position. Three of the Company’s board members have investments in this same firm, with an aggregate ownership fraction of less than 1% ownership position. The Company’s Chairman and CEO, Thinh Tran, is a member of Envivio’s board of directors.
