NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1. Basis of Presentation

In the opinion of management, the accompanying Unaudited Condensed Consolidated Interim Financial Statements (“financial statements”) of Adaptec, Inc. and its wholly-owned subsidiaries (collectively, the “Company”) have been prepared on a consistent basis with the March 31, 2005 audited consolidated financial statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth therein. The financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission (“SEC”), and, therefore, omit certain information and footnote disclosure necessary to present the statements in accordance with accounting principles generally accepted in the United States of America. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2005, which was filed with the SEC on June 14, 2005. The third quarters of fiscal 2006 and 2005 ended on December 30, 2005 and December 31, 2004, respectively. For presentation purposes, the accompanying financial statements have been shown as ending on December 31. The results of operations for the third quarter and first nine months of fiscal 2006 are not necessarily indicative of the results to be expected for the entire fiscal year.

Certain reclassifications have been made to prior period reported amounts to conform to the current period presentation, including reclassification of auction rate securities from cash and cash equivalents to marketable securities. Previously, such auction rate securities were classified as cash and cash equivalents. Accordingly, the Company has revised its presentation and made adjustments to the accompanying Unaudited Condensed Consolidated Statement of Cash Flows to reflect the gross purchases and sales of these auction rate securities as investing activities. This adjustment resulted in a net increase in cash used for investing activities by $12.6 million in the first nine months of fiscal 2005. This reclassification had no impact on previously reported results of operations, operating cash flows or working capital of the Company.

In addition, as discussed in Note 4, on September 30, 2005, the Company completed the sale to International Business Machines (“IBM”) of its IBM i/p Series RAID component business (“IBM i/p Series RAID Business”) and on September 29, 2005 the Company’s Board of Directors approved management’s recommendation to divest its systems business. Both of these businesses have been accounted for as discontinued operations. Accordingly, the Company has reclassified the underlying Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows and related disclosures for all periods presented to reflect the IBM i/p Series RAID Business and the systems business as discontinued operations. In the third quarter of fiscal 2006, in conjunction with the renegotiation of a customer supply contract, the Company decided to retain a product line that was previously classified within discontinued systems business. Accordingly, the Company has reclassified the underlying Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows and related disclosures for all periods presented to reflect that product line as part of continuing operations.

Unless otherwise indicated and other than balance sheet amounts as of March 31, 2005, the Notes to the Unaudited Condensed Consolidated Financial Statements relate to the discussion of the Company’s continuing operations.

The glossary of key acronyms used in the Company’s industry and accounting rules and regulations referred to within this Quarterly Report on Form 10-Q is listed in alphabetical order in Note 20.

2. Recent Accounting Pronouncements

In June 2005, the FASB issued SFAS No. 154, which changes the requirements for the accounting for, and reporting of, a change in accounting principle. Previously, most voluntary changes in accounting principles were required to be recognized by way of a cumulative effect adjustment within net income during the period of the change. SFAS No. 154 requires retrospective application to prior periods’ financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005; however, the Statement does not change the transition provisions of any existing accounting pronouncements. The Company’s results of operations and financial condition will only be impacted following the adoption of SFAS No. 154 if it implements changes in accounting principles that are addressed by the standard or corrects accounting errors in future periods.

In December 2004, the FASB issued SFAS No. 123(R). This statement replaces SFAS No. 123, amends SFAS No. 95 and supersedes APB Opinion No. 25. SFAS No. 123(R) requires companies to apply a fair-value based measurement method in accounting for share-based payment transactions with employees and to record compensation expense for all stock awards granted and to awards modified, repurchased or cancelled after the required effective date. In addition, the Company is required to record compensation expense (as previous awards continue to vest) for the unvested portion of previously granted awards that remain outstanding at the date of adoption. In April 2005, the SEC approved that SFAS No. 123(R) will be effective for annual periods, as opposed to interim periods as originally issued by the FASB, beginning after June 15, 2005. In March 2005, the SEC issued SAB 107, which offers guidance on SFAS No. 123(R). SAB 107 was issued to assist preparers by simplifying some of the implementation challenges of SFAS No. 123(R) while enhancing the information that investors receive. The Company intends to use the modified prospective method, which will result in a significant increase to expenses on the Company’s consolidated financial statements beginning April 1, 2006. The Company cannot currently quantify the impact of the adoption of SFAS No. 123(R) and SAB 107 as it will depend on the amount of share-based payments that the Company grants in the future as well as other variables that affect the fair market value estimates which cannot be forecasted at this time. The pro forma disclosures of the impact of SFAS No. 123 provided in Note 3 may not be representative of the impact of adopting this statement.

In November 2004, the FASB issued SFAS No. 151, which clarifies the accounting for abnormal amounts of facility expense, freight, handling costs and wasted materials (spoilage) to require them to be recognized as current-period charges. This statement is effective for inventory costs incurred during fiscal years beginning after June 15, 2005. Earlier application is permitted. The adoption of this standard is not expected to have a material impact on the Company’s financial statements.

3. Stock-Based Compensation

The Company accounts for stock-based compensation using the intrinsic-value-based method, which is in accordance with APB Opinion No. 25 as interpreted by FIN 44, and complies with the disclosure provisions of SFAS No. 148, an amendment of SFAS No. 123. The Company accounts for equity instruments issued to non-employees in accordance with the provisions of SFAS No. 123 and EITF No. 96-18, which requires that such equity instruments be recorded at their fair value on the measurement date, which is typically the date of grant.

The following table illustrates the effect on net income (loss) and net income (loss) per share as if the Company had applied the fair value recognition provisions of SFAS No. 123 to employee and director stock option plans, including shares issued under the Company’s ESPP, collectively called “options,” for all periods presented:

	Three-Month Period Ended								Nine-Month Period Ended
	December 31, 2005				December 31, 2004				December 31, 2005				December 31, 2004
	(in thousands, except per share amounts)
Net income (loss), as reported		$	(3,261	)		$	22,489			$	(145,040	)		$	14,436
Add: Deferred stock-based compensation expense included in reported net income (loss)		223				775				1,526				2,453
Deduct: Total stock-based compensation expense determined under the fair value-based method, net of tax		(3,740		)		(3,837		)		(10,120		)		(9,923		)
Pro forma net income (loss)		$	(6,778	)		$	19,427			$	(153,634	)		$	6,966
Basic net income (loss) per share:
As reported		$	(0.03	)		$	0.20			$	(1.28	)		$	0.13
Pro forma		$	(0.06	)		$	0.17			$	(1.36	)		$	0.06
Diluted net income (loss) per share:
As reported		$	(0.03	)		$	0.17			$	(1.28	)		$	0.12
Pro forma		$	(0.06	)		$	0.15			$	(1.36	)		$	0.06

SFAS No. 123 requires the use of option pricing models that were not developed for use in valuing employee stock options. The Black-Scholes option pricing model, used by the Company, was developed for use in estimating the fair value of short-lived exchange traded options that have no vesting restrictions and are fully transferable. In addition, option pricing models require the input of highly subjective assumptions, including the option’s expected life and the price volatility of the underlying stock.

The fair value of options granted in the third quarter and first nine months of fiscal 2006 and 2005, as reported were estimated at the date of grant using the Black-Scholes valuation model with the following weighted average assumptions:

	Three-Month Period Ended						Nine-Month Period Ended
	December 31, 2005			December 31, 2004			December 31, 2005			December 31, 2004
Employee Stock Option Plans:
Expected life (in years)		4.3			2.0			2.5			2.3
Risk-free interest rates		4.4	%		3.1	%		4.1	%		3.0	%
Expected volatility		52	%		39	%		38	%		44	%

4. Discontinued Operations

IBM i/p Series RAID Business:

On September 30, 2005, the Company entered into a series of arrangements with IBM pursuant to which the Company sold its IBM i/p Series RAID Business to IBM for approximately $22.0 million plus $1.3 million for certain fixed assets. In addition, IBM purchased certain related inventory at the Company’s net book value of $0.8 million. Expenses incurred in the transaction primarily included costs of approximately $0.5 million for legal and accounting fees. In addition, the Company accrued $0.3 million for lease obligations. Under the terms of the agreements, the Company granted IBM a nonexclusive license to certain intellectual property and sold to IBM substantially all of the assets dedicated to the engineering and manufacturing of RAID controllers and connectivity products for the IBM i/p Series RAID Business. Under the terms of the nonexclusive license, IBM will pay royalties to the Company for the sale of its board-level products over the next six quarters, which will be recognized as contingent consideration in discontinued operations when earned. In the third quarter of fiscal 2006, the Company received royalties of $3.5 million, which the Company recorded in “Income (loss) from disposal of discontinued operations, net of taxes,” in the Unaudited Condensed Consolidated Statements of Operations.

Net revenues and the components of income (loss) related to these discontinued operations, which were previously included in the Company’s DPS segment, were as follows:

	Three-Month Period Ended							Nine-Month Period Ended
	December 31, 2005			December 31, 2004				December 31, 2005				December 31, 2004
	(in thousands)
Net revenues		$	237		$	9,870			$	20,046			$	15,056
Income (loss) from discontinued operations before income taxes		424			(3,341		)		(14,239		)		(8,945		)
Provision for (benefit from) income taxes		282			(11,714		)		(360		)		(903		)
Income (loss) from discontinued operations, net of taxes		$	142		$	8,373			$	(13,879	)		$	(8,042	)

The components of net assets, at the time of the sale of the IBM i/p Series RAID Business, were as follows:

	September 30, 2005
	(in thousands)
Inventories		$	838
Prepaid expenses		11,139
Property and equipment, net		3,326
Other intangibles, net		10,958
Other long-term assets		24,507
Accrued liabilities		(10,051		)
Other long-term liabilities		(10,625		)
Net assets of discontinued operations		$	30,092

Accounts receivable related to the IBM i/p Series RAID Business were not included in discontinued operations as the Company will be retaining these assets.

Systems Business:

On September 29, 2005, the Company’s Board of Directors approved management’s recommendation to divest its systems business, which includes substantially all of the operating assets and cash flows that were obtained through the Snap Appliance and Eurologic Systems acquisitions as well as internally developed hardware and software. In connection with this action, the Company has classified the systems business as a discontinued operation in the financial statements. The Company has entered into an exclusive arrangement with an investment banker to sell this business and expects to receive proceeds, less cost to sell, in excess of its carrying value.

In the third quarter of fiscal 2006, in conjunction with the renegotiation of a customer supply contract, the Company decided to retain a product line that was previously classified within discontinued systems business. Accordingly, the Company has reclassified the underlying Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows and related disclosures for all periods presented to reflect that product line as part of continuing operations.

Net revenues and the components of net loss related to the discontinued operations, were as follows:

	Three-Month Period Ended								Nine-Month Period Ended
	December 31, 2005				December 31, 2004				December 31, 2005				December 31, 2004
	(in thousands)
Net revenues		$	18,958			$	23,205			$	53,704			$	56,395
Loss from discontinued operations before provision for income taxes		(3,501		)		(2,729		)		(16,651		)		(10,510		)
Provision for (benefit from) income taxes		790				120				515				(1,460		)
Loss from discontinued operations, net of taxes		$	(4,291	)		$	(2,849	)		$	(17,166	)		$	(9,050	)

The components of net assets related to the discontinued operations were as follows:

	December 31, 2005
	(in thousands)
Inventories		$	4,522
Prepaid expenses		75
Current assets of discontinued operations		4,597

Total assets of discontinued operations		30,481
Accrued liabilities		(5,336		)
Current liabilities of discontinued operations		(5,336		)
Net assets of discontinued operations		$	25,145

Accounts receivable related to the systems business were not included in discontinued operations as the Company intends to retain these assets.

6. Goodwill and Other Intangible Assets

Goodwill:

Goodwill allocated to the Company’s reportable segments and changes in the carrying amount of goodwill for the first nine months of fiscal 2006 was as follows:

	OEM			Channel			Total
	(in thousands)
Balance at March 31, 2005	$	48,783		$	42,703		$	91,486
Goodwill adjustments	(166		)	(718		)	(884		)
Goodwill impairment	(48,617		)	(41,985		)	(90,602		)
Balance at December 31, 2005	$	—		$	—		$	—

In the first quarter of fiscal 2006, adjustments were made to goodwill for changes to the acquisition-related restructuring reserves and other purchase price adjustments for the IBM i/p Series RAID business and Snap Appliance. As a result of the segment reorganization, discussed in Note 15, an assessment of the recoverability of goodwill was performed. Impairment of goodwill is tested at the Company’s operating segment level by comparing each segment’s carrying amount, including goodwill, to the fair value of that segment. To determine fair value, the Company’s review process uses the income, or discounted cash flows, approach and the market approach. In performing its analysis, the Company uses the best information available under the circumstances, including reasonable and supportable assumptions and projections. If the carrying amount of the operating segment exceeds its implied fair value, goodwill is considered impaired and a second step is performed to measure the amount of impairment loss, if any. As a result of this review, the Company wrote-off its entire balance of goodwill of $90.6 million in the second quarter of fiscal 2006. Factors that led to this conclusion were industry technology changes such as the shift from parallel to serial technology and the migration of core functionality to server chipsets; required increased investments that eventually led the Company to sell the IBM i/p Series RAID Business and the proposed sale of the systems business; continued losses associated with sales of systems to IBM; and general market conditions.

The components of interest and other income for the third quarter and first nine months of fiscal 2006 and 2005, were as follows:

	Three-Month Period Ended								Nine-Month Period Ended
	December 31, 2005				December 31, 2004				December 31, 2005				December 31, 2004

In the first nine months of fiscal 2006, the Company repurchased $23.2 million in aggregate principal amount of its 3% Convertible Subordinated Notes (“3% Notes”) on the open market for an aggregate price of $23.1 million, resulting in an immaterial loss. The loss on extinguishment of debt has been included in “Interest and other income” in the Company’s Unaudited Condensed Consolidated Statement of Operations. Subsequent to the third quarter of fiscal 2006, the Company repurchased $1.4 million of the 3% Notes on the open market for $1.3 million, resulting in an immaterial gain. The gain on extinguishment of debt will be included in “Interest and other income” in the Company’s Consolidated Statement of Operations in the fourth quarter of fiscal 2006.

In June 2004, the Company, Nevada SCSI Enterprises, Inc. and Thomas A. Gafford (jointly, “NSE”) entered into a license and release agreement, pursuant to which the Company paid NSE $1.3 million as a one-time, fully paid-up license payment fee to settle NSE’s claims that some of the Company’s products infringed certain patents. The license and release agreement expressly excluded any sales of products made by Eurologic prior to the Company’s April 2003 acquisition of Eurologic. In November 2004, the Company exercised its option to secure a license and release with respect to such Eurologic sales by payment to NSE of a royalty fee of $0.4 million. The Company has filed a claim against the Eurologic acquisition Holdback for the $0.4 million royalty it paid with respect to Eurologic’s pre-acquisition sales. The Eurologic shareholders are disputing the Company’s right to withhold the $0.4 million from the Holdback. See Note 13 for further discussion of the Eurologic Holdback.

8. Restructuring Charges

In the third quarter of fiscal 2006, management approved and initiated a plan to restructure the operations of the Company by simplifying its infrastructure. The third quarter of fiscal 2006 restructuring plan eliminated certain duplicative resources in all functions of the organization worldwide, due in part, to the discontinued operations and vacated redundant facilities in order to reduce the combined cost structure of the Company. This resulted in a restructuring charge of $2.4 million for the third quarter of fiscal 2006.

The Company recorded provision adjustments of $0.2 million and $0.7 million in the third quarter of fiscal 2006 and first nine months of fiscal 2006, respectively, related to severance and benefits as actual costs were lower than anticipated and additional lease costs related to the estimated loss on facilities that the Company subleased. The provision adjustments also include additional lease costs related to the estimated loss on facilities that the Company subleased in connection with Snap Appliance acquisition (Note 18). These provision adjustments pertained to the restructuring plans that the Company implemented in each quarter of fiscal 2005, and restructuring plans that it implemented in fiscal 2004, fiscal 2003, fiscal 2002 and fiscal 2001. The fiscal 2004 restructuring plan was completed in the first quarter of fiscal 2006. The third quarter of fiscal 2005 restructuring plan and fourth quarter of fiscal 2005 restructuring plan were completed in the third quarter of fiscal 2006. For a complete discussion of all restructuring actions that were implemented prior to fiscal 2006, please refer to the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2005. All expenses, including adjustments, associated with the Company’s restructuring plans are included in “Restructuring charges” in the Unaudited Condensed Consolidated Statements of Operations and are not allocated to segments, but are managed at the corporate level.

The activity in the accrued restructuring reserves related to all of the plans was as follows for the first nine months of fiscal 2006:

	Severance And Benefits				Other Charges				Total
	(in thousands)
Reserve balance at March 31, 2005		$	896			$	1,627		$	2,523
Q3’06 Restructuring Plan		1,738				695			2,433
Provision adjustments		(288		)		716			428
Cash paid		(1,886		)		(1,037		)	(2,923		)
Reserve balance at December 31, 2005		$	460			$	2,001		$	2,461

The Company anticipates that the remaining restructuring reserve balance of $2.5 million will be substantially paid out by the first quarter of fiscal 2009, primarily attributable to longer term lease obligations. The remaining restructuring reserve balance is reflected both in “Accrued liabilities” and “Other long-term liabilities” in the Unaudited Condensed Consolidated Balance Sheet.

9. Other Charges (Gains)

In January 2006, the Company entered into a three-year contract manufacturing agreement with Sanmina-SCI whereby Sanmina-SCI has assumed manufacturing operations of Adaptec products. In addition, the Company sold certain manufacturing assets, buildings and improvements and inventory located in Singapore to Sanmina-SCI. In connection with this agreement, the Company recorded a loss on disposal of assets of $1.5 million that was recorded in the third quarter of fiscal 2006 in “Other charges (gains)” on the Unaudited Condensed Consolidated Statements of Operations. Please refer to Note 17 for further details.

In October 2004, the Company completed the sale of certain properties in Milpitas, California that were previously classified as held for sale. Net proceeds from the sale of the properties aggregated $9.6 million, which exceeded the Company’s final revised fair value of $6.8 million. As a result, a gain on the sale of the properties of $2.8 million was recorded in the third quarter of fiscal 2005 as a credit to “Other charges (gains)” in the Unaudited Condensed Consolidated Statements of Operations.

10. Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share gives effect to all potentially dilutive common shares outstanding during the period, which include certain stock options and warrants, calculated using the treasury stock method, and convertible notes which are potentially dilutive at certain earnings levels, and are computed using the if-converted method.

A reconciliation of the numerator and denominator of the basic and diluted income (loss) per share computations for continuing operations, discontinued operations and net income (loss) were as follows:

	Three-Month Period Ended
	Continuing Operations							Discontinued Operations							Net Income (Loss)
	December 31, 2005				December 31, 2004			December 31, 2005				December 31, 2004			December 31, 2005				December 31, 2004

Diluted loss per share from continuing operations, discontinued operations and net loss for the third quarter and first nine months of fiscal 2006 was based only on the weighted-average number of shares outstanding during the period, as the inclusion of any common stock equivalents would have been anti-dilutive. In addition, certain potential common shares were excluded from the diluted computation from continuing operations, discontinued operations and net income for the third quarter and first nine months of fiscal 2005 because their inclusion would have been anti-dilutive. The items excluded for the third quarters and first nine months of fiscal 2006 and 2005 from continuing operations, discontinued operations and net income (loss) were as follows:

	Three-Month Period Ended				Nine-Month Period Ended
	December 31, 2005		December 31, 2004		December 31, 2005		December 31, 2004
	(in thousands)

¾% Notes		19,224		—		19,224		—
3% Notes		783		—		1,030		2,298

(1) In connection with the issuance of its ¾% Notes, the Company entered into a derivative financial instrument to repurchase up to 19,224,000 shares of its common stock, at the Company’s option, at specified prices in the future to mitigate any potential dilution as a result of the conversion of the ¾% Notes. For further discussion on this derivative financial instrument, please refer to Note 6 of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2005.

11. Comprehensive Income (Loss)

The Company’s comprehensive income (loss), which consisted of net loss and the changes in net unrealized gains (losses) on marketable securities, net of taxes, and foreign currency translation adjustments, net of taxes, were as follows:

	Three-Month Period Ended								Nine-Month Period Ended
	December 31, 2005				December 31, 2004				December 31, 2005				December 31, 2004
	(in thousands)
Net income (loss)		$	(3,261	)		$	22,489			$	(145,040	)		$	14,436

Total		$	(2,091	)		$	706

12. Income Taxes

Income tax provisions for interim periods are based on the Company’s estimated annual income tax. The estimated annual tax for fiscal 2006 primarily consists of foreign taxes related to the Company’s foreign subsidiaries and interest accrued on prior years’ tax disputes. The Company currently has a full valuation allowance on its net U.S. deferred tax assets. The Company is in ongoing negotiations with the IRS with regard to its various tax disputes that may result in settlement of certain issues. The Company’s tax rate for the period in which a settlement is reached will be impacted if the settlement materially differs from the amounts previously accrued. The tax rate for the third quarter and the first nine months of fiscal 2005 also differed from the combined United States Federal and state statutory income tax rate of 40% due to tax benefits of $21.9 million and $31.9 million respectively from discrete events relating to the method and amount of settled controversies. As a result of the settlements, $21.9 million previously recorded as a tax provision was reversed during the third quarter of fiscal 2005. In addition, $4.1 million previously recorded as a tax provision was reclassified as a reduction to additional paid-in capital, $1.8 million previously recorded as a tax provision has been reversed, and a $4.0 million tax benefit associated with a refund claim has been recognized during the second quarter of fiscal 2005.

13. Commitments and Contingencies

The Company has been, or is, subject to IRS audits for its fiscal years 1994 through 2003. The fiscal 1994 through fiscal 1996 cycle, which is docketed in the United States Tax Court, was resolved in December 2001. The outcome did not have a material adverse effect on the Company’s financial position or results of operations, as sufficient tax provisions had been made. The final Tax Court stipulation will be filed when the subsequent audit cycles are completed. Tax credits that were generated but not used in subsequent years may be carried back to the fiscal 1994 to 1996 audit cycle.

On December 15, 2000, the Company received a statutory notice of deficiency from the IRS with respect to its Federal income tax return for fiscal 1997. The Company filed a Petition with the United States Tax Court on March 14, 2001, contesting the asserted deficiencies. Settlement agreements have been filed with the United States Tax Court on all but one issue. The Company believes that the final outcome of all issues will not have a material adverse impact on its financial position or results of operations, as the Company believes that it has meritorious defenses against the asserted deficiencies and any proposed adjustments and that it has made sufficient tax provisions. However, the Company cannot predict with certainty how these matters will be resolved and whether it will be required to make additional payments.

In addition, the IRS is currently auditing the Company’s Federal income tax returns for fiscal 1998 through fiscal 2003. In the third quarter of fiscal 2005, the Company resolved all issues for fiscal 1998 through fiscal 2001, other than the rollover impact of any potential resolution on the remaining fiscal 1997 issue and tax credits that were generated but not used in subsequent years that may be carried back. The Company believes that it has provided sufficient tax provisions for these years and the ultimate outcome of the IRS audits will not have a material adverse impact on its financial position or results of operations in future periods. However, the Company cannot predict with certainty how these matters will be resolved and whether it will be required to make additional tax payments.

The Company is a party to other litigation matters and claims, including those related to intellectual property, which are normal in the course of its operations, and while the results of such litigation matters and claims cannot be predicted with certainty, the Company believes that the final outcome of such matters will not have a material adverse impact on its financial position or results of operations. However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, the Company’s business, financial condition, results of operations and cash flows could be materially and adversely affected.

In connection with the Company’s acquisitions of Snap Appliance, Eurologic, Elipsan Limited (“Elipsan”), and Platys Communications, Inc. (“Platys”), a portion of the purchase price and other future payments totaling $6.7 million, $3.8 million, $2.0 million and $15.0 million, respectively, were held back (the “Holdbacks”) for unknown liabilities that may have existed as of the acquisition dates. The Company has asserted claims against the Snap Appliance, Eurologic and Platys Holdbacks totaling $3.0 million, $1.5 million and $0.7 million, respectively. The Elipsan Holdback of $2.0 million was paid in the second quarter of fiscal 2006.

14. Guarantees

Intellectual Property Indemnification Obligations

The Company has entered into agreements with customers and suppliers that include intellectual property indemnification obligations. These indemnification obligations generally require the Company to compensate the other party for certain damages and costs incurred as a result of third party intellectual property claims arising from these transactions. In each of these circumstances, payment by the Company is conditional on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party’s claims. Further, the Company’s obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements. It is not possible to make a reasonable estimate of the maximum potential amount of future payments under these or similar agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, the Company has not incurred significant costs to defend lawsuits or settle claims related to such agreements and no amount has been accrued in the accompanying financial statements with respect to these indemnification guarantees.

Product Warranty

The Company provides an accrual for estimated future warranty costs based upon the historical relationship of warranty costs to sales. The estimated future warranty obligations related to product sales are recorded in the period in which the related revenue is recognized. The estimated future warranty obligations are affected by product failure rates, material usage and replacement costs incurred in correcting a product failure. If actual product failure rates, material usage or replacement costs differ from the Company’s estimates, revisions to the estimated warranty obligations would be required; however, the Company made no adjustments to pre-existing warranty accruals in the first nine months of fiscal 2006 and 2005.

A reconciliation of the changes to the Company’s warranty accrual for the first nine months of fiscal 2006 and 2005 was as follows:

	Nine-Month Period Ended
	December 31, 2005				December 31, 2004
	(in thousands)
Balance at beginning of period		$	2,084			$	1,598
Warranties assumed		—				2,562
Warranties provided		3,958				3,932
Actual costs incurred		(4,053		)		(4,188		)
Warranties classified as current liabilities of discontinued operations (Note 4)		(359		)		—
Balance at end of period		$	1,630			$	3,904

15. Segment Reporting

In the second quarter of fiscal 2006, the Company reorganized its internal organization structure related to its OEM and Channel segments. Where previously the Company’s former OEM and Channel segments each offered an integrated set of customer-focused products, the new organization is managed at the product level.

Following the reorganization, the Company operated in two reportable segments: DPS and DSG. A description of the types of customers or products and services provided by each reportable segment is as follows:

· DPS provides storage products and currently sells all of its storage technologies in various form factors, such as board-level products, ASICs, RAID enclosures and stand-alone software. The Company sells these products directly to OEMs, ODMs that supply OEMs, VARs and end users through its network of distribution and reseller customers.

· DSG provides high-performance I/O connectivity and digital media products for personal computing platforms, including notebook and desktop PCs. The Company sells these products to retailers, OEMs and distributors.

The unallocated corporate income and expenses, which are in the “Other” category, include amortization of acquisition-related intangible assets, restructuring charges, goodwill impairment, other charges (gains), interest and other income, interest expense, all administrative expenses and certain research and development, selling and marketing expenses.

Summarized financial information on the Company’s reportable segments, under the new organizational structure, is shown in the following table. The segment financial data for the third quarter of fiscal 2005 and first nine months of fiscal 2005 and fiscal 2006 has been restated to reflect this change. There were no inter-segment revenues for the periods shown below. The Company does not separately track all tangible assets or depreciation by operating segments nor are the segments evaluated under these criteria. Segment financial information is summarized as follows for the third quarters and first nine months of fiscal 2006 and 2005:

17. Assets Held for Sale

The Company entered into on December 23, 2005 and subsequently closed on January 9, 2006 a three-year contract manufacturing agreement with Sanmina—SCI whereby Sanmina—SCI has assumed manufacturing operations of Adaptec products. In addition, the Company sold certain manufacturing assets , buildings and improvements and inventory located in Singapore with respect to printed circuit board assemblies and storage system manufacturing operations to Sanmina—SCI for the Company’s net book value of approximately $27.0 million, subject to final closing adjustments for $25.5 million (net of closing costs of $0.5 million) resulting in a loss on disposal of assets of $1.5 million that was recorded in the third quarter of fiscal 2006 in “Other charges (gains)” on the Unaudited Condensed Consolidated Statements of Operations. Those assets have been reclassified to “Assets held for sale” on the Unaudited Condensed Consolidated Balance Sheets.

18. Business Acquisitions

The acquisitions described below were previously accounted for as purchase transactions and, accordingly, the results of operations and financial position of the acquired businesses were included in the Company’s financial statements as of the respective effective dates of the acquisitions. However, as a result of the sale of the IBM i/p Series RAID Business and the Company’s plan to divest its systems business, the assets expected to be sold have been reclassified as Assets and Liabilities of Discontinued Operations on the Unaudited Condensed Consolidated Balance Sheet at December 31, 2005 and the related operations have been reclassified to “Income (loss) from discontinued operations, net of taxes” on the Unaudited Condensed Consolidated Statements of Operations, as discussed in Note 4.

IBM i/p Series RAID: On June 29, 2004, the Company completed the acquisition of the IBM i/p Series RAID component business line consisting of certain purchased RAID data protection intellectual property, semiconductor designs and assets, and licensed from IBM related RAID intellectual property.

The licensing agreement granted the Company the right to use IBM’s RAID technology and embedded Power PC technology for the Company’s internal and external RAID products to be sold to IBM and other customers. In conjunction with the acquisition, the Company also entered into a three-year exclusive product supply agreement under which the Company agreed to supply RAID software, firmware and hardware to IBM for use in IBM’s iSeries and pSeries servers. The Company also entered into an agreement for IBM to provide silicon wafer manufacturing processing services to the Company for the term of the supply agreement at agreed upon rates.

The final purchase price was $49.3 million, which consisted of a cash payment to IBM of $47.5 million, warrants valued at $1.1 million, net of registration costs, and transaction costs of $0.7 million. This purchase price included a final adjustment of $0.2 million in the first quarter of fiscal 2006 to both goodwill and acquisitions costs. In connection with the acquisition, the Company issued a warrant to IBM to purchase 250,000 shares of the Company’s common stock at an exercise price of $8.13 per share. The warrant has a term of 5 years from the date of issuance and is immediately exercisable. The warrant was valued using the Black- Scholes valuation model using a volatility rate of 62%, a risk-free interest rate of 3.9% and an estimated life of 5 years. The transaction costs consisted primarily of legal, valuation and other fees. The IBM i/p Series RAID business was included in the Company’s DPS segment.

Snap Appliance: On July 23, 2004, the Company completed the acquisition of Snap Appliance, a provider of NAS products, to expand its product offerings in the external storage market and to deliver cost-effective, scalable and easy-to-use DAS, NAS, Fibre Channel and IP-based SAN products from the workgroup to the data center. The final purchase price was $83.7 million, consisting of $76.7 million in cash and transaction fees and $7.0 million related to the fair value of assumed stock options to purchase 1.2 million shares of the Company’s common stock. This purchase price included a final adjustment of $0.7 million in the first half of fiscal 2006 to both goodwill and acquisitions costs. The assumed stock options were valued using the Black-Scholes valuation model with the following assumptions: volatility rate of 58%; a risk-free interest rate of 2.6%; and an estimated life of 2.25 years. In the first quarter of fiscal 2006, adjustments of $0.7 were made to both goodwill and the acquisition costs.

Of the total assumed stock options, stock options to purchase approximately 0.7 million shares of the Company’s common stock, with exercise prices ranging between $1.42 and $5.66 per share, were unvested (the “Snap Unvested Options”). The Snap Unvested Options have a ten-year term and vest primarily over four years from the date of grant. The intrinsic value of the Snap Unvested Options of $3.6 million was accounted for as deferred stock-based compensation and is being recognized as compensation expense over the related vesting periods.

In addition, a management incentive program was established to pay former employees of Snap Appliance cash payments totaling $13.8 million, which is being paid, contingent upon their employment with the Company, over a two-year period through the second quarter of fiscal 2007. Payments under the management incentive program will be expensed as employees meet their employment obligations or are recorded as part of the Snap Appliance acquisition-related restructuring for involuntary terminations by the Company. Any amounts outstanding as of the completion of the sale of the systems business will be accelerated.

Acquisition-Related Restructuring:

During the first quarter of fiscal 2006, the Company finalized its Snap Appliance integration plan to eliminate certain duplicative resources, including severance and benefits in connection with the involuntary termination of approximately 24 employees, exiting duplicative facilities and disposing of duplicative assets. The acquisition-related restructuring liabilities were accounted for under EITF No. 95-3 and therefore were included in the purchase price allocation. The Company recorded a total liability of $6.7 million for these activities, of which the original estimate of $6.0 million was recorded in the second

quarter of fiscal 2005 and adjustments were recorded in each subsequent quarter through the first quarter of fiscal 2006 totaling $0.7 million. Any further changes to the Company’s finalized plan will be accounted for under SFAS No. 146 and will be recorded in “Restructuring charges” in the Unaudited Condensed Consolidated Statements of Operations. In the third quarter of fiscal 2006, the Company recorded additional adjustments of $0.2 million due to additional lease costs related to the estimated loss of facilities that the Company subleased, which was recorded in “Restructuring charges” in the Unaudited Condensed Consolidated Statements of Operations (Note 8). As of December 31, 2005, the Company had utilized $4.2 million of these charges. The Company anticipates that the remaining restructuring reserve balance of $2.7 million will be paid out by the third quarter of fiscal 2012, primarily related to long-term facility leases.

The activity in the accrued restructuring reserve related to the Snap Appliance acquisition-related restructuring plan was as follows for the first nine months of fiscal 2006:

	Severance And Benefits				Other Charges				Total
	(in thousands)
Snap Appliance Acquisition-Related Restructuring Plan:
Reserve balance at March 31, 2005		$	155			$	2,901		$	3,056
Adjustments		(49		)		244			195
Cash paid		(60		)		(538		)	(598		)
Reserve balance at December 31, 2005		$	46			$	2,607		$	2,653

In-process Technology

As part of the purchase agreements of the IBM i/p Series RAID business and Snap Appliance, certain amounts of the purchase prices were allocated to acquired in-process technology which were determined through established valuation techniques in the high-technology computer industry and written off in the first and second quarter of fiscal 2005, respectively, because technological feasibility had not been established and no alternative future uses existed. The values were determined by estimating the net cash flows and discounting the estimated net cash flows to their present values. A summary of the amounts written off were as follows:

(1) The in-process projects were related to designing semiconductors and related boards and enhancements to RAID and firmware code.

(2) The identified in-process projects were related to operating system enhancements and system functionality improvements.

The net cash flows from the identified projects were based on estimates of revenues, cost of revenues, research and development expenses, including costs to complete the projects, selling, marketing and administrative expenses, royalty expenses and income taxes from the projects. The Company believes the assumptions used in the valuations were reasonable at the time of the acquisitions. The estimated net revenues and gross margins were based on management’s projections of the projects and were in line with industry averages. Estimated total net revenues from the projects of the IBM i/p Series RAID business and Snap Appliance were expected to grow through fiscal 2009 and decline thereafter as other new products were expected to become available. Estimated operating expenses included research and development expenses and selling, marketing and administrative expenses based upon historical and expected direct expense levels and general industry metrics. Estimated research and development expenses included costs

to bring the projects to technological feasibility and costs associated with activities undertaken to correct errors or keep products updated with current information (also referred to as “maintenance” research and development) after a product is available for general release to customers. These activities range from 0% to 5% of net revenues for the in-process technologies.

The effective tax rate used in the analysis of the in-process technologies reflects a combined historical industry specific average for the United States Federal and state statutory income tax rates. The cost of capital reflects the estimated time to complete the projects and the level of risk involved. The following discount rates were used in computing the present value of net cash flows for the acquired companies: between 23% and 28% for the IBM i/p Series RAID business and approximately 24% for Snap Appliance.

The percentage of completion was determined using costs incurred by the IBM i/p Series RAID business and Snap Appliance prior to their respective acquisition dates compared to the estimated remaining research and development to be completed to bring the projects to technological feasibility. The Company estimated, as of the respective acquisition dates for the IBM i/p Series RAID business and Snap Appliance, that the projects were approximately 50% complete and 25% complete, respectively. All projects outstanding as of the acquisition date for the IBM i/p Series RAID business ceased as of September 30, 2005 with the sale of the business. All projects outstanding as of the acquisition date for Snap Appliance were completed as of September 30, 2005.

Pro forma financial information for the first nine months of fiscal 2005 has not been disclosed as the acquisitions of the IBM i/p Series RAID business and Snap Appliance were included as part of discontinued operations.

19. Subsequent Events

On January 31, 2006, the Company and one of its wholly owned subsidiaries signed a definitive agreement with Sanmina—SCI Corporation and its wholly owned subsidiary, Sanmina-SCI USA, Inc. (the”Definitive Agreement”), for the sale of the Company’s OEM block-based systems business for $14.6 million, of which $5.0 million will be received over the next two years. In addition, Sanmina-SCI USA agreed to pay the Company contingent consideration of up to an additional $12.0 million if certain revenue levels are achieved over the next three years. Sanmina intends to operate the Company’s OEM block-based business within Sanmina-SCI’s ODM subsidiary, Newisys.

Under the terms of the Definitive Agreement, Sanmina-SCI USA will assume most OEM contracts for its block-based systems customers. The sale of the OEM block-based systems business, in terms of future expected revenues, represents approximately half of the planned divestiture of the systems business that was included in discontinued operations as of December 31, 2005. In return, Sanmina-SCI USA will supply the Company with block-based system products for the continued sale through the channel. This arrangement will cease upon identifying a buyer for the remainder of the Company’s systems business, which represents block- and file-based systems, including Snap-branded solutions. At that time, the new buyer would assume the supply agreement and channel distribution of all products of the systems business.

The Company expects to record a gain of approximately $13.0 million, subject to final closing adjustments, on the sale of the OEM block-based systems business in the fourth quarter of fiscal 2006, which will be recorded in “Income (loss) from disposal of discontinued operations, net of taxes,” in the Consolidated Statements of Operations.

All forward-looking statements included in this document are based on information available to us on the date hereof, and we assume no obligation to update any such forward-looking statements, except as may otherwise be required by law.

Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth in the “Risk Factors” section and elsewhere in this document. In evaluating our business, current and prospective investors should consider carefully these factors in addition to the other information set forth in this document.

While management believes that the discussion and analysis in this report is adequate for a fair presentation of the information presented, we recommend that you read this discussion and analysis in conjunction with our Annual Report on Form 10-K for the fiscal year ended March 31, 2005. Our critical accounting policies have not changed from our fiscal year ended March 31, 2005. For a complete discussion of our critical accounting policies, please refer to our Annual Report on Form 10-K for the fiscal year ended March 31, 2005.

As discussed below, on September 30, 2005, we completed the sale to International Business Machines, or IBM, of our IBM i/p Series RAID component business, or IBM i/p Series RAID Business, and on September 29, 2005, our Board of Directors approved management’s recommendation to divest our systems business. Both of these businesses have been accounted for as discontinued operations. Accordingly, we have reclassified the underlying Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows and related disclosures for all periods presented to reflect the IBM i/p Series RAID Business and systems business as discontinued operations. In the third quarter of fiscal 2006, in conjunction with the renegotiation of a customer supply contract, we decided to retain a product line that was previously classified within discontinued systems business. Accordingly, we have reclassified the underlying Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows and related disclosures for all periods presented to reflect that product line as part of continuing operations.

Unless otherwise indicated and other than balance sheet amounts as of March 31, 2005, the following discussion pertains only to our continuing operations.

For your convenience, we have included, in Note 20 to the Notes to the Unaudited Condensed Consolidated Financial Statements, a Glossary that contains a list of (1) key acronyms commonly used in our industry that are used in this Quarterly Report and (2) accounting rules and regulations that are also referred to herein.

Results of Operations

Overview

Our new management team is continuing to perform a thorough analysis of our operations, which it initiated in the first quarter of fiscal 2006, and has begun making a detailed plan of our corporate strategy.

This analysis of our operations includes a review of all aspects of our business, including our product portfolio, our relationships with strategic partners and our research and development focus. To date, we have implemented the following steps:

· On January 31, 2006, we and one of its wholly owned subsidiaries signed a definitive agreement with Sanmina-SCI Corporation and its wholly owned subsidiary, Sanmina-SCI USA, Inc., or the Definitive Agreement, for the sale of our OEM block-based systems business for $14.6 million, of which $5.0 million will be received over the next two years. In addition, Sanmina-SCI USA agreed to pay us contingent consideration of up to an additional $12.0 million if certain revenue levels are achieved over the next three years. Sanmina intends to operate our OEM block-based business within Sanmina-SCI’s ODM subsidiary, Newisys. We expect to record a gain of approximately $13.0 million, subject to final closing adjustments, on the sale of the OEM block-based systems business in the fourth quarter of fiscal 2006.

· We entered into on December 23, 2005 and subsequently closed on January 9, 2006 a three-year contract manufacturing agreement with Sanmina-SCI whereby Sanmina-SCI has assumed manufacturing operations of Adaptec products. In addition, we sold certain manufacturing assets, buildings and improvements and inventory located in Singapore with respect to printed circuit board assemblies and storage system manufacturing operations to Sanmina-SCI for our net book value of approximately $27.0 million, subject to final closing adjustments for $25.5 million (net of closing costs of $0.5 million) resulting in a loss on disposal of assets of $1.5 million that was recorded in the third quarter of fiscal 2006 in “Other charges (gains)” on the Unaudited Condensed Consolidated Statements of Operations. Those assets have been reclassified to “Assets held for sale” on the Unaudited Condensed Consolidated Balance Sheets.

· On September 30, 2005, we sold our IBM i/p Series RAID Business to IBM for approximately $22.0 million plus $1.3 million for certain fixed assets. In addition, IBM purchased certain related inventory at our net book value of $0.8 million. We also granted IBM a nonexclusive license to certain intellectual property and sold to IBM substantially all of the assets dedicated to the engineering and manufacturing of RAID controllers and connectivity products for the IBM i/p Series RAID Business. Under the terms of the nonexclusive license, IBM will pay us royalties for the sale of our board-level products over the next six quarters, which will be recognized as contingent consideration in discontinued operations when earned. In the third quarter of fiscal 2006, we received royalties of $3.5 million, which we recorded in “Income (loss) from disposal of discontinued operations, net of taxes,” in the Unaudited Condensed Consolidated Statements of Operations.

· On September 29, 2005, our Board of Directors approved management’s recommendation to divest our systems business, which includes substantially all of the operating assets and cash flows that were obtained through the Snap Appliance and Eurologic Systems acquisitions as well as internally developed hardware and software. In connection with this action, we have classified the systems business as a discontinued operation in the financial statements. We expect to receive proceeds, less cost to sell, in excess of our carrying value. In the third quarter of fiscal 2006, in conjunction with the renegotiation of a customer supply contract, we decided to retain a product line that was previously classified within discontinued systems business. Accordingly, we have reclassified the underlying Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows and related disclosures for all periods presented to reflect that product line as part of continuing operations.

· We reorganized our internal organization structure related to our OEM and Channel segments in the second quarter of fiscal 2006. Where previously our former OEM and Channel segments each offered an integrated set of customer-focused products, the new organization is managed at the

product level. Our reportable segments currently are DPS and DSG. As a result of the segment reorganization, an assessment of the recoverability of goodwill was performed and we wrote-off our entire balance of goodwill of $90.6 million in the second quarter of fiscal 2006. All prior periods have been restated to reflect our new segments.

The actions that we have taken and the actions that we are considering could adversely affect our business and financial results in the short-term, may not have the long-term beneficial results that we intend and could result in the following:

· Loss of customers;

· Loss of employees;

· Increased dependency on suppliers;

· Supply issues;

· Reduced revenue base;

· Impairment of our assets;

· Increased operating costs; and

· Material restructuring charges.

Our future revenue growth remains largely dependent on the success of our data protection solutions, new OEM design wins and our products addressing new technologies (i.e., Serial Attached SCSI, SATA and iSCSI).

In the third quarter of fiscal 2006, our revenues decreased 17% as compared to the third quarter of fiscal 2005 primarily reflecting a decline in sales volumes and the average selling prices of our parallel SCSI products, which was partially offset by sales of our serial products primarily sold to OEMs and one-time benefits associated with the renegotiation of a customer supply contract related to our systems products. The improvement in gross margin in the third quarter of fiscal 2006 compared to the third quarter of fiscal 2005 was primarily due to decreased component costs and one-time benefits associated with the renegotiation of a customer supply contract related to our systems products, which was partially offset by changes in our product mix, which led to lower average margins. Operating expenses decreased in the third quarter of fiscal 2006 as compared to the third quarter of fiscal 2005, primarily as a result of reduced headcount related to the ServerEngines and Vitesse strategic alliances we entered into in the fourth quarter of fiscal 2005 and decreased infrastructure spending and reduced headcount as a result of restructuring programs implemented in fiscal 2005 and the third quarter of fiscal 2006.

The following table sets forth the items in the Unaudited Condensed Consolidated Statements of Operations as a percentage of net revenues (references to notes in the footnotes to this table are to the Notes to Unaudited Condensed Consolidated Financial Statements appearing in this report):

(1) In the third quarter of fiscal 2006, we implemented a restructuring plan (Note 8) and recorded a loss on disposal of assets of $1.5 million (Note 17). In the third quarter of fiscal 2005, we implemented a restructuring plan, recorded a gain of $2.8 million on the sale of certain properties (Note 9), made a payment of $0.4 million to Nevada SCSI Enterprises, Inc., or NSE, in the form of a license fee (Note 7) and received a tax benefit from the settlements of disputes with the IRS. These transactions affect the comparability of this data.

(2) In the first nine months of fiscal 2006, we recorded a goodwill impairment charge of $90.6 million (Note 6), implemented a restructuring plan in the third quarter of fiscal 2006 (Note 8) and recorded a loss on disposal of assets of $1.5 million (Note 17). In the first nine months of fiscal 2005, we recorded a gain of $2.8 million on the sale of certain properties (Note 9), made a payment of $1.7 million to NSE in the form of a license fee (Note 7) and implemented restructuring plans in the first, second and third quarters of fiscal 2005. These transactions affect the comparability of this data.

Net Revenues.

	Three-Month Period Ended									Nine-Month Period Ended
	December 31, 2005			December 31, 2004			Percentage Change			December 31, 2005			December 31, 2004			Percentage Change
	(in millions, except percentages)
Segment Net Revenues:
DPS		$	69.1		$	84.9		(19	)%		$	208.1		$	263.7		(21	)%
DSG		8.7			8.6			1	%		28.6			28.6			0	%
Total Net Revenues		77.8			93.5			(17	)%		236.7			292.3			(19	)%

Net revenues from our DPS segment decreased by $15.8 million and $55.6 million in the third quarter and first nine months of fiscal 2006, respectively, as compared to the corresponding periods of fiscal 2005, reflecting a decline in sales volumes and average selling prices of our parallel SCSI products, which was partially offset by sales of our serial products primarily to OEMs and one-time benefits associated with the renegotiation of a customer supply contract related to our systems products. The decline in sales volumes of our SCSI products was primarily attributable to the transition from our Ultra 160 products to Ultra 320 products in which we have a lower market share, a shift to lower cost SATA solutions in which we have a lower market share and motherboards that contain built-in SCSI I/O functionality, thus reducing our average selling price.

Net revenues from our DSG segment increased by $0.1 million in the third quarter compared to the third quarter of fiscal 2005 as a result of increased sales of our digital media products and sales of storage products that were introduced in the fourth quarter of fiscal 2005, partially offset by the decline in sales volumes of our SCSI-based desktop computer products. We expect revenues from our SCSI-based desktop computer products to continue to decline as OEMs are incorporating other connectivity technologies directly into their products. Net revenues from our DSG segment remained relatively flat in the first nine months of fiscal 2006 compared to the first nine months of fiscal 2005.

	Three-Month Period Ended						Nine-Month Period Ended
	December 31, 2005			December 31, 2004			December 31, 2005			December 31, 2004
Geographical Revenues:
North America		37	%		26	%		36	%		34	%
Europe		31	%		39	%		31	%		33	%
Pacific Rim		32	%		35	%		33	%		33	%
Total Geographical Revenues		100	%		100	%		100	%		100	%

Our North America revenues increased as a percentage of our total gross revenues in the third quarter and first nine months of fiscal 2006 as compared to the corresponding periods of fiscal 2005 primarily as a result of one-time benefits associated with the renegotiation of a customer supply contract related to our systems products and increased sales related to a North America OEM, partially offset by a decline in channel sales in North America. Included in European revenues for the third quarter and first nine months of fiscal 2006 was $1.0 million and $11.7 million, respectively, of a last time buy customer order.

A small number of our customers account for a substantial portion of our net revenues, and we expect that a limited number of customers will continue to represent a substantial portion of our net revenues for the foreseeable future. IBM and Dell accounted for 34% and 17% of our total net revenues, respectively, in the third quarter of fiscal 2006. IBM and Dell accounted for 38% and 14% of our total net revenues, respectively, in the third quarter of fiscal 2005. IBM and Dell accounted for 30% and 16% of our total net revenues, respectively, in the first nine months of fiscal 2006. IBM, Dell and Synnex accounted for 26%, 14% and 11% of our total net revenues, respectively, in the first nine months of fiscal 2005.

Gross Margin.

	Three-Month Period Ended											Nine-Month Period Ended
	December 31 2005				December 31, 2004				Percentage Change			December 31, 2005				December 31, 2004				Percentage Change
	(in millions, except percentages)
Gross Profit		$	29.0			$	33.9			(15	)%		$	80.3			$	127.4			(37	)%
Gross Margin		37		%		36		%					34		%		44		%

The improvement in gross margin in the third quarter of fiscal 2006 compared to the third quarter of fiscal 2005 was primarily due to decreased component costs and one-time benefits associated with the renegotiation of a customer supply contract related to our systems products, which was partially offset by changes in our product mix, which led to lower average margins.

The decline in gross margin in the first nine months of fiscal 2006 compared to the first nine months of fiscal 2005 was primarily due to changes in our product and customer mix, which led to lower average margins, fixed costs associated with our manufacturing facilities that were distributed over lower revenue levels and an excess inventory adjustment of $1.9 million recorded in the first nine months of fiscal 2006 related to the transition of our products to comply with the European Union Restriction on Use of Hazardous Substances Directive, or RoHS Directive. This was partially offset by decreased component costs and one-time benefits associated with the renegotiation of a customer supply contract related to our systems products. Our gross margins will be significantly impacted in the future by the mix of OEM and channel revenue.

Research and Development Expense.

	Three-Month Period Ended									Nine-Month Period Ended
	December 31, 2005			December 31, 2004			Percentage Change			December 31, 2005			December 31, 2004			Percentage Change
	(in millions, except percentages)
Research and Development		$	14.4		$	21.3		(32	)%		$	47.3		$	68.2		(31	)%

The decrease in research and development expense in the third quarter and first nine months of fiscal 2006 as compared to the corresponding periods of fiscal 2005 was primarily a result of reduced headcount achieved as a result of the ServerEngines and Vitesse strategic alliances we entered into in the fourth quarter of fiscal 2005, decreased infrastructure spending and reduced headcount as a result of restructuring programs implemented in fiscal 2005 and decreased deferred compensation charges of $0.3 million and $1.7 million in the third quarter and first nine months of fiscal 2006, respectively compared to the corresponding periods of fiscal 2005. Deferred compensation charges represented the vesting of assumed stock options in connection with our acquisition of Platys Communications, Inc., or Platys, in August 2001. Deferred compensation charges associated with the Platys acquisition ceased in the first quarter of fiscal 2006.

Selling, Marketing and Administrative Expense.

	Three-Month Period Ended									Nine-Month Period Ended
	December 31, 2005			December 31, 2004			Percentage Change			December 31, 2005			December 31 2004			Percentage Change
	(in millions, except percentages)
Selling, Marketing and Administrative		$	15.7		$	17.8		(12	)%		$	49.7		$	55.0		(10	)%

The decrease in selling, marketing and administrative expense in the third quarter and first nine months of fiscal 2006 as compared to the corresponding periods of fiscal 2005 was primarily a result of

decreased spending due to reductions of our workforce and infrastructure spending as a result of the restructuring plans we implemented in fiscal 2005 and the third quarter of fiscal 2006. This was partially offset by compensation of $1.2 million recorded in the first quarter of fiscal 2006 related to retirement costs of our former Chief Executive Officer.

Amortization of Acquisition-Related Intangible Assets.

	Three-Month Period Ended									Nine-Month Period Ended
	December 31, 2005			December 31, 2004			Percentage Change			December 31, 2005			December 31, 2004			Percentage Change
	(in millions, except percentages)
Amortization of Acquisition-Related Intangible Assets		$	1.7		$	2.2		(23	)%		$	5.5		$	7.1		(23	)%

Acquisition-related intangible assets include patents, core and existing technologies, covenants-not-to-compete, customer relationships and trade names. We amortize the acquisition-related intangible assets over periods which reflect the pattern in which the economic benefits of the assets are expected to be realized, which is primarily using the straight-line method over their estimated useful lives, ranging from three months to five years.

The decrease in amortization of acquisition-related intangible assets in the third quarter and first nine months of fiscal 2006 compared to the corresponding periods of fiscal 2005 was due to intangible assets that became fully amortized in August 2005 associated with our Platys acquisition and certain intangible assets that became fully amortized in fiscal 2005 associated with our acquisition of Eurologic Systems Group Limited in April 2003.

Restructuring Charges.

Restructuring Charges		$	2.6		$	2.2		16	%		$	3.1		$	5.0		(38	)%

In the third quarter of fiscal 2006, management approved and initiated a plan to restructure our operations by simplifying our infrastructure. The third quarter of fiscal 2006 restructuring plan eliminated certain duplicative resources in all functions of the organization worldwide, due in part, to the discontinued operations and vacated redundant facilities in order to reduce our combined cost structure. This resulted in a restructuring charge of $2.4 million for the third quarter of fiscal 2006.

As a result of our third quarter of fiscal 2006 restructuring plan, we expect to reduce our annual infrastructure spending by approximately $3 million, of which 24%, 34% and 42% will be reflected as a reduction in cost of revenues, research and development and selling, marketing and administrative expense, respectively.

We recorded provision adjustments of $0.2 million and $0.7 million in the third quarter of fiscal 2006 and first nine months of fiscal 2006, respectively, related to severance and benefits as actual costs were lower than anticipated and additional lease costs related to the estimated loss on facilities that we subleased. The provision adjustments also include additional lease costs related to the estimated loss on facilities that we subleased in connection with the Snap Appliance acquisition (Note 18). These provision adjustments pertained to restructuring plans that we implemented in each quarter of fiscal 2005, and restructuring plans that we implemented in fiscal 2004, fiscal 2003, fiscal 2002 and fiscal 2001. The fiscal 2004 restructuring plan was completed in the first quarter of fiscal 2006. The third quarter of fiscal 2005 restructuring plan and fourth quarter of fiscal 2005 restructuring plan were completed in the third quarter

of fiscal 2006. For a complete discussion of all restructuring actions that were implemented prior to fiscal 2006, please refer to the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2005. All expenses, including adjustments, associated with our restructuring plans are included in “Restructuring charges” in the Unaudited Condensed Consolidated Statements of Operations and are not allocated to segments, but are managed at the corporate level.

In conjunction with the agreements entered into with Sanmina—SCI on December 23, 2005 related to the transaction that subsequently closed on January 9, 2006, management approved and initiated a plan to restructure our work force in our Singapore operations. To the extent that the employees are not be hired by Sanmina—SCI, the employees will be terminated by us over approximately the next two quarters. We estimate that we will incur future severance costs in the range of $5 million and $6 million.

Goodwill Impairment.

Goodwill Impairment		$	—		$	—		—		$	90.6		$	—		100	%

Goodwill is not amortized, but instead is reviewed annually and whenever events or circumstances occur which indicate that goodwill might be impaired. As a result of the segment reorganization discussed above and in Note 15 to the Notes to Unaudited Condensed Consolidated Financial Statements, an assessment of the recoverability of goodwill was performed. Impairment of goodwill is tested at our operating segment level by comparing each segment’s carrying amount, including goodwill, to the fair value of that segment. To determine fair value, our review process uses the income, or discounted cash flows, approach and the market approach. In performing our analysis, we use the best information available under the circumstances, including reasonable and supportable assumptions and projections. If the carrying amount of the operating segment exceeds its implied fair value, goodwill is considered impaired and a second step is performed to measure the amount of impairment loss, if any. As a result of this review, we wrote-off our entire balance of goodwill of $90.6 million in the second quarter of 2006. Factors that led to this conclusion were industry technology changes such as the shift from parallel to serial technology and the migration of core functionality to server chipsets; required increased investments that eventually led us to sell the IBM i/p Series RAID Business and the proposed sale of the systems business; continued losses associated with sales of systems to IBM; and general market conditions.

Other Charges (Gains)		$	1.5		$	(2.8	)		(153	)%		$	1.5		$	(2.8	)		(153	)%

We entered into on December 23, 2005 and subsequently closed on January 9, 2006 a three-year contract manufacturing agreement with Sanmina—SCI whereby Sanmina—SCI has assumed manufacturing operations of Adaptec products. In addition, we sold certain manufacturing assets, buildings and improvements and inventory located in Singapore with respect to printed circuit board assemblies and storage system manufacturing operations to Sanmina—SCI for our net book value of approximately $27.0 million, subject to final closing adjustments for $25.5 million (net of closing costs of $0.5 million) resulting in a loss on disposal of assets of $1.5 million that was recorded in the third quarter of fiscal 2006 in “Other charges (gains)” on the Unaudited Condensed Consolidated Statements of Operations. Those assets have been reclassified to “Assets held for sale” on the Unaudited Condensed Consolidated Balance Sheets.

In October 2004, we completed the sale of certain properties in Milpitas, California that were previously classified as held for sale. Net proceeds from the sale of the properties aggregated $9.6 million, which exceeded our final revised fair value of $6.8 million. As a result, a gain on the sale of the properties of $2.8 million was recorded in the third quarter of fiscal 2005 as a credit to “Other charges (gains)” in the Unaudited Condensed Consolidated Statements of Operations.

Interest and Other Income.

Total Interest and Other Income		4.5			3.1				45	%		12.6				8.6				47	%

Interest and other income is primarily attributable to interest income earned on our cash, cash equivalents and marketable securities, fluctuations in foreign currency gains or losses, realized gains and losses on marketable securities, sublease income received from third parties and loss from the repurchase of our 3% Convertible Subordianted Notes, or 3% Notes.

The increase in interest and other income in the third quarter and first nine months of fiscal 2006 as compared to the corresponding periods of fiscal 2005 was primarily due to higher interest rates earned on our cash, cash equivalents and marketable securities in the first nine months of fiscal 2006 and a one-time fully paid-up license payment fee of $1.7 million to NSE, which was recorded in the first nine months of fiscal 2005, primarily for historical products that incorporated certain technology. This was partially offset by foreign currency fluctuations primarily related to the Euro and a loss of $0.1 million on the repurchase of our 3% Notes for the first nine months of fiscal 2006. For further discussion on the settlement with NSE and gain on the sale of the property, please refer to Note 7 to the Notes to Unaudited Condensed Consolidated Financial Statements.

Interest Expense		$	(0.8	)		$	(1.1	)		(30	)%		$	(2.6	)		$	(3.4	)		(22	)%

Interest expense is primarily associated with our ¾% Convertible Senior Subordinated Notes, or ¾% Notes, and 3% Notes issued in December 2003 and March 2002, respectively. The decrease in interest expense for the third quarter and first nine months of fiscal 2006 compared to the corresponding periods of fiscal 2005 was primarily due to the reduction in the outstanding balances of the 3% Notes, as we repurchased $23.2 million in aggregate principal amount of our 3% Notes during the first nine months of fiscal 2006.

Income Taxes.

Provision for (Benefit from) Income Taxes		$	(0.6	)		$	(21.8	)		(97	)%		$	3.2		$	(31.5	)		(110	)%

Income tax provisions for interim periods are based on our estimated annual effective income tax. The estimated annual tax for fiscal 2006 primarily consists of foreign taxes related to our foreign subsidiaries and interest accrued on prior years’ tax disputes. We currently have a full valuation allowance on our net U.S. deferred tax assets. We are engaged in ongoing negotiations with the IRS with regard to various tax disputes that may result in settlement of certain issues. Our tax rate for the period in which a settlement is reached will be impacted if the settlement materially differs from the amounts previously accrued. The tax rate for the third quarter and first nine months of fiscal 2005 differed from the combined United States Federal and state statutory income tax rate of 40% primarily due to certain acquisition-related intangible assets, excluding goodwill, that are not fully deductible for tax purposes and interest accrued on prior years’ tax disputes. The tax rate for the third quarter and the first nine months of fiscal 2005 also differed from the combined United States Federal and state statutory income tax rate of 40% due to tax benefits of $21.9 million and $31.9 million respectively from discrete events relating to the method and amount of settled controversies. As a result of the settlements, $21.9 million previously recorded as a tax provision was reversed during the third quarter of fiscal 2005. In addition, $4.1 million previously recorded as a tax provision was reclassified as a reduction to additional paid-in capital, $1.8 million previously recorded as a tax provision has been reversed, and a $4.0 million tax benefit associated with a refund claim has been recognized during the second quarter of fiscal 2005.

Historically our effective tax rate was benefited by a Singapore tax holiday relating to certain of our products. The contract manufacturing agreement entered into with Sanmina-SCI could jeopardize this holiday which may cause our effective tax rate to increase. We currently have alternative plans to reduce our effective tax rate; however, if these plans are not successful, our effective tax rate could increase, which would adversely affect our financial results.

IBM i/p Series RAID Business: On September 30, 2005, we entered into a series of arrangements with IBM pursuant to which we sold our IBM i/p Series RAID Business to IBM for approximately $22.0 million plus $1.3 million for certain fixed assets. In addition, IBM purchased certain related inventory at our net book value of $0.8 million. Expenses incurred in the transaction primarily included costs of approximately $0.5 million for legal and accounting fees. In addition, we accrued $0.3 million for lease obligations. Under the terms of the agreements, we granted IBM a nonexclusive license to certain intellectual property and sold to IBM substantially all of the assets dedicated to the engineering and manufacturing of RAID controllers and connectivity products for the IBM i/p Series RAID Business. Under the terms of the nonexclusive license, IBM will pay us royalties for the sale of our board-level

products over the next six quarters, which will be recognized as contingent consideration in discontinued operations when earned. In the third quarter of fiscal 2006, we received royalties of $3.5 million, which we recorded in “Income (loss) from disposal of discontinued operations, net of taxes,” in the Unaudited Condensed Consolidated Statements of Operations.

Systems Business: On September 29, 2005, our Board of Directors approved management’s recommendation to divest our systems business, which includes substantially all of the operating assets and cash flows that were obtained through the Snap Appliance and Eurologic Systems acquisitions as well as internally developed hardware and software. In connection with this action, we have classified the systems business as a discontinued operation in the financial statements. We have entered into an exclusive arrangement with an investment banker to sell this business and expect to receive proceeds, less cost to sell, in excess of our carrying value.

In the third quarter of fiscal 2006, in conjunction with the renegotiation of a customer supply contract, we decided to retain a product line that was previously classified within discontinued systems business. Accordingly, we have reclassified the underlying Unaudited Condensed Consolidated Statements of Operations and Unaudited Condensed Consolidated Statements of Cash Flows and related disclosures for all periods presented to reflect that product line as part of continuing operations.

Liquidity and Capital Resources

Key Components of Cash Flows

Cash provided by operations was $8.4 million in the first nine months of fiscal 2006 as compared to cash used for operations of $16.0 million in the first nine months of fiscal 2005. Cash provided by operations for the first nine months of fiscal 2006 resulted primarily from the benefit of non-cash items included in operating results, which primarily consisted of an impairment of goodwill of $90.6 million and depreciation and amortization of $19.4 million. This was partially offset by our loss from continuing operations of $110.5 million. Additional factors included changes to working capital assets and liabilities that decreased cash provided by operating activities of continuing operations by $1.2 million and increased cash provided by operating activities of discontinued operations of $7.9 million. Cash used for the first nine months of fiscal 2005 resulted primarily from changes to working capital assets and liabilities that decreased cash used for operating activities of continuing operations and discontinued operations by $21.5 million and $28.0 million, respectively, and non-cash effect on tax settlement of $26.0 million. This was partially offset by our income from continuing operations of $31.5 million and depreciation and amortization of $28.4 million.

Cash used for investing activities was $321.6 million in the first nine months of fiscal 2006, which was primarily due to net sales and maturities of restricted marketable securities and marketable securities, net of purchases, of $340.3 million and purchases of property and equipment from continuing operations of $6.5 million, partially offset by proceeds from the sale of the IBM i/p Series RAID Business of $24.1 million. Cash used for investing activities was $4.2 million in the first nine months of fiscal 2005, which was primarily due to cash used to acquire Snap Appliance and the IBM i/p Series RAID business of $65.4 million, purchases of property and equipment from continuing operations of $8.1 million and cash used in investing activities of discontinued operations of $63.0 million. This was offset by net purchases of restricted marketable securities and marketable securities, net of sales and maturities, of $125.1 million and proceeds from the sale of long-lived assets of $9.6 million

Cash used for financing activities of $19.7 million in the first nine months of fiscal 2006 was primarily driven by the repurchase of $23.2 million in aggregate principal amount of our 3% Notes for $23.0 million. Cash provided by financing activities was $5.4 million in the first nine months of fiscal 2005, which related to net proceeds received from our issuance of common stock in connection with purchases made under our employee stock purchase plan and stock option exercises.

Liquidity. At December 31, 2005, we had $532.3 million in cash, cash equivalents and marketable securities, of which approximately $91.1 million was held by our Singapore subsidiary. In the fourth quarter of fiscal 2005, we repatriated $360.6 million of undistributed earnings from Singapore to the United States and incurred a tax liability of $17.6 million. The repatriated amounts will be used to fund a qualified Domestic Reinvestment Plan, as required by the American Jobs Creation Act of 2004. If we do not spend the repatriated funds in accordance with our reinvestment plan, we may incur additional tax liabilities. We have not provided for U.S. deferred income taxes or foreign withholding taxes on the remaining undistributed earnings since these earnings totaling approximately $255.6 million are intended to be reinvested internationally indefinitely. Although we do not have any current plans to repatriate the remaining undistributed earnings from our Singapore subsidiary to our United States parent company, if we were to do so, additional income taxes at the combined United States Federal and state statutory rate of approximately 40% could be incurred from the repatriation.

At December 31, 2005, we had $237.0 million of aggregate principal amount in convertible notes outstanding, consisting of $12.0 million in aggregate principal amount of our 3% Notes that are due in March 2007 and $225.0 million in aggregate principal amount of our ¾% Notes that are due in December 2023.

We are required to maintain restricted cash or investments to serve as collateral for the first ten scheduled interest payments on our ¾% Notes. As of December 31, 2005, we had $4.7 million of restricted cash and restricted marketable securities, consisting of United States government securities, of which $1.6 million was classified as short-term and $3.1 million was long-term.

The IRS is currently auditing our income tax returns for fiscal 1997 and final settlement agreements have been filed with the United States Tax Court on all but one issue. In addition, the IRS is auditing our Federal income tax returns for fiscal 1998 through fiscal 2003. We have resolved all issues for fiscal 1998 through fiscal 2001 other than the rollover impact of any potential resolution on the remaining fiscal 1997 issue and tax credits that were generated but not used in subsequent years that may be carried back. The fiscal 2002 and 2003 audit is ongoing. We believe that we have sufficient tax provisions for these years. We believe the final outcome of the IRS audits will not have a material adverse impact on our liquidity. However, we cannot predict with certainty how these matters will be resolved and whether we will be required to make additional payments.

As of December 31, 2005, we did not have any material changes to our contractual obligations that were disclosed in the Liquidity section of our Form 10-K for the fiscal year ended March 31, 2005. However, as part of the three-year contract manufacturing agreement entered into with Sanmina-SCI on January 9, 2006, we are committed to purchasing majority of our products from Sanmina-SCI. In addition, as part of the agreement, we entered into a put agreement which entitles Sanmina-SCI to return any equipment not used within six months of the close of the transaction. We reserved for this potential liability as of December 31, 2005.

We believe that liquidity provided by our existing working capital, together with expected cash flows from operations and available sources of equity and equipment financing, will be sufficient to support our operations through at least the next twelve months. However, should prevailing economic conditions and/or financial, business and other factors beyond our control adversely affect our estimates of our future cash requirements, we would be required to fund our cash requirements by alternative financing. There can be no assurance that additional financing, if needed, would be available on terms acceptable to us or at all.

Recent Accounting Pronouncements

In June 2005, the FASB issued SFAS No. 154, which changes the requirements for the accounting for, and reporting of, a change in accounting principle. Previously, most voluntary changes in accounting

principles were required to be recognized by way of a cumulative effect adjustment within net income during the period of the change. SFAS No. 154 requires retrospective application to prior periods’ financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005; however, the Statement does not change the transition provisions of any existing accounting pronouncements. Our results of operations and financial condition will only be impacted following the adoption of SFAS No. 154 if it implements changes in accounting principles that are addressed by the standard or corrects accounting errors in future periods.

In December 2004, the FASB issued SFAS No. 123(R). This statement replaces SFAS No. 123, amends SFAS No. 95 and supersedes APB Opinion No. 25. SFAS No. 123(R) requires companies to apply a fair-value based measurement method in accounting for share-based payment transactions with employees and to record compensation expense for all stock awards granted and to awards modified, repurchased or cancelled after the required effective date. In addition, we are required to record compensation expense (as previous awards continue to vest) for the unvested portion of previously granted awards that remain outstanding at the date of adoption. In April 2005, the SEC approved that SFAS No. 123(R) will be effective for annual periods, as opposed to interim periods as originally issued by the FASB, beginning after June 15, 2005. In March 2005, the SEC issued SAB 107, which offers guidance on SFAS No. 123(R). SAB 107 was issued to assist preparers by simplifying some of the implementation challenges of SFAS No. 123(R) while enhancing the information that investors receive. We intend to use the modified prospective method, which will result in a significant increase to expenses on our consolidated financial statements beginning April 1, 2006. We cannot currently quantify the impact of the adoption of SFAS No. 123(R) and SAB 107 as it will depend on the amount of share-based payments that we grant in the future as well as other variables that affect the fair market value estimates which cannot be forecasted at this time. The pro forma disclosures of the impact of SFAS No. 123 provided in Note 3 of the Notes to the Unaudited Condensed Consolidated Financial Statements may not be representative of the impact of adopting this statement.

RISK FACTORS

Our business faces significant risks. The risks described below may not be the only risks we face. Additional risks that we do not yet know of or that we currently think are immaterial may also impair our business operations. If any of the events or circumstances described in the following risks actually occurs, our business, financial condition or results of operations could suffer, and the trading price of our common stock could decline.

We depend on contract manufacturers and subcontractors, and if they fail to meet our manufacturing needs, it could delay shipments of our products and result in the loss of customers. We rely on contract manufacturers for manufacturing of our products and subcontractors for the assembly and packaging of the integrated circuits included in our products and for the assembly. On January 9, 2006 we entered into a three-year contract manufacturing agreement with Sanmina-SCI whereby Sanmina-SCI has assumed manufacturing operations of Adaptec products. If the transition of the manufacturing facilities does not go as expected it could result in loss of customers or revenue, which would have an adverse effect on our financial results. We have no long-term agreements with our assembly and packaging subcontractors. For example, we employ Quanta Computer, Inc. to manufacture certain products related to the acquisition of Snap Appliance. We also employ Amkor Technology and Advanced Semiconductor Engineering for our final assembly and test operations related to our ASIC products. We cannot assure you these subcontractors will continue to be able and willing to meet our requirements for these components or services. For example, in the third quarter of fiscal 2005, Quanta Computer, Inc. could not meet our manufacturing needs and as a result initial product delivery dates committed to customers were not met. Any significant disruption in supplies from or degradation in the quality of components or services supplied by, these contract manufacturers and subcontractors could delay shipments and result in the loss of customers or revenues, which could have an adverse effect on our financial results.

Actions that we have taken and the actions that we are considering could adversely affect our business and financial results in the short-term, and may not have the long-term beneficial results that we intend. Our new management team is continuing to perform a thorough analysis of our operations, which it initiated in the first quarter of fiscal 2006, and has begun making a detailed plan of our corporate strategy. This analysis of our operations includes a review of all aspects of our business, including our product portfolio, our relationships with strategic partners and our research and development focus. To date we have implemented the following steps described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations—Overview.”

• Loss of customers;

• Loss of employees;

• Increased dependency on suppliers;

• Supply issues;

• Reduced revenue base;

• Impairment of our assets;

• Increased operating costs; and

• Material restructuring charges.

If we are unable to successfully complete the divestiture of our systems business it could result in an adverse effect on our business and financial results. Completing the systems divestiture could cause significant diversions of management time and resources. In addition, if the anticipated proceeds, less cost to sell, prove to be less than anticipated, it could lead to an impairment of our assets. Additionally, customers for our systems products could be reluctant to continue to buy from us. We may not be successful in selling the systems business on terms that are acceptable to us or might not be able to find a buyer for the business. We may not be successful in overcoming these risks or any other problems encountered in connection with this divesture which may adversely affect our business, financial position and operating results.

Our operating results have fluctuated in the past, and are likely to continue to fluctuate, and if our future results are below the expectations of investors or securities analysts, the market price of our common stock would likely decline significantly. Our quarterly operating results have fluctuated in the past, and are likely to vary significantly in the future, based on a number of factors related to our industry and the markets for our products. Factors that are likely to cause our operating results to fluctuate include those discussed in this Risk Factors section. In the first nine months of fiscal 2006, our operating results were materially affected by unusual charges, including a goodwill impairment charge of $90.6 million and an excess inventory adjustment of $1.9 million related to the transition of our products to comply with the RoHS Directive.

Our operating expenses are largely based on anticipated revenues, and a large portion of our expenses, including facility costs and salaries, are fixed in the short term. As a result, lower than anticipated revenues for any reason could cause significant variations in our operating results from quarter to quarter.

Due to the factors summarized above, and the other risks described in this section, we believe that you should not rely on period-to-period comparisons of our financial results as an indication of our future performance. In the event that our operating results fall below the expectations of market analysts or investors, the market price of our common stock could decline substantially.

Our operating results may be adversely affected by unfavorable economic and market conditions and the uncertain geopolitical environment. Adverse economic conditions in some markets may impact our business, which could result in:

• Reduced demand for our products as a result of a decrease in capital spending by our customers;

• Increased price competition for our products;

• Increased risk of excess and obsolete inventories;

• Excess facilities and manufacturing capacity; and

• Higher overhead costs as a percentage of revenues.

Demand for our products would likely be negatively affected if demand in the server and network storage markets declines. For example, demand in the server market declined slightly in fiscal 2002 and fiscal 2003, which contributed to a decline in our net revenues. It is difficult to predict future server sales growth, if any. In addition, other technologies may replace the technologies used in our existing products and the acceptance of our products using new technologies in the market may not be widespread, which could adversely affect our revenues.

Because our sales are made by means of standard purchase orders rather than long-term contracts, if demand for our customers’ products declines or if our customers do not control their inventories effectively, they may cancel or reschedule shipments previously ordered from us or reduce their levels of purchases from us. The volume and timing of orders received during a quarter are difficult to forecast. Our customers generally order based on their forecasts and they frequently encounter uncertain and changing demand for their

products. If demand falls below such forecasts or if our customers do not control their inventories effectively, they may cancel or reschedule shipments previously ordered from us. Our customers have from time to time in the past canceled or rescheduled shipments previously ordered from us, and we cannot assure you that they will not do so in the future. In addition, because our sales are made by means of standard purchase orders rather than long-term contracts, we cannot assure you that these customers will continue to purchase quantities of our products at current levels, or at all. Historically, we have set our operating budget based on forecasts of future revenues because we do not have significant backlog. Because much of our operating budget is relatively fixed in the short-term, if revenues do not meet our expectations, then our financial results will be adversely affected.

We depend on a few key customers and the loss of any of them could significantly reduce our revenues. Historically, a small number of our customers has accounted for a significant portion of our revenues. During the first nine months of fiscal 2006, sales to the ten customers from which we received the greatest revenues accounted for approximately 93% of our total gross revenues. In addition, IBM and Dell represented 30% and 16%, respectively, of our total net revenues in the first nine months of fiscal 2006. We believe that our major customers continually evaluate whether or not to purchase products from alternate or additional sources. Additionally, customers’ economic and market conditions frequently change. Accordingly, we cannot assure you that a major customer will not reduce, delay or eliminate its purchases from us, which would likely cause our revenues to decline. In addition, we do not carry credit insurance on our accounts receivables and any difficulty in collecting outstanding amounts due from our customers, particularly customers that place larger orders or experience financial difficulties, could adversely affect our revenues and our net income. Because our sales are made by means of standard purchase orders rather than long-term contracts, we cannot assure you that these customers will continue to purchase quantities of our products at current levels, or at all.

If there is a shortage of components used in our customers’ products, our sales may decline, which could adversely affect our results of operations and financial position. If our customers are unable to purchase certain components which are embedded into their products, their demand for our products may decline. For example, beginning in the fourth quarter of fiscal 2005, we experienced the impact of other companies’ enterprise drive shortages, which reduced the demand for our SCSI-related products from our OEM and Channel customers. This negatively affected our revenues in the fourth quarter of fiscal 2005. In addition, our customers may be impacted by component shortages if components are not available that comply with the RoHS Directive. Similar shortages of components used in our customers’ products could adversely affect our net revenues and financial results in future periods.

We may be subject to a higher effective tax rate that could negatively affect our results of operations and financial position. Our effective tax rate is benefited by a Singapore tax holiday relating to certain of our products. The tax holiday package, which is effective until fiscal 2010, provides that profits derived from certain products may be exempt from tax, subject to certain conditions. If we do not meet the conditions and requirements of the tax holiday in Singapore, our effective tax rate may increase, which would adversely affect our financial results. The contract manufacturing agreement entered into with Sanmina-SCI could jeopardize this holiday. We currently have alternative plans to reduce our effective tax rate; however, if these plans are not successful, our effective tax rate could increase, which would adversely affect our financial results.

We held approximately $91.1 million of cash, cash equivalents and marketable securities at our subsidiary in Singapore at December 31, 2005. During the fourth quarter of fiscal 2005, we repatriated $360.6 million of cash from Singapore to the United States in connection with the American Jobs Creation Act of 2004 which provides a one-time deduction of 85% for certain dividends from controlled foreign corporations. If the amount repatriated does not qualify for the one-time deduction, we could incur additional income taxes at up to the United States Federal statutory rate of 35%, which would negatively affect our results of operations and financial condition.

Our dependence on new products may cause our net revenues to fluctuate or decline. Our future success significantly depends upon our completing and introducing enhanced and new products at competitive prices and performance levels in a timely manner. The success of new product introductions depends on several factors, including the following:

• Designing products to meet customer needs;

• Product costs;

• Timely completion and introduction of new product designs;

• Quality of new products;

• Differentiation of new products from those of our competitors; and

• Market acceptance of our products.

Our product life cycles in each of our segments may be as brief as 12 months. As a result, we believe that we will continue to incur significant expenditures for research and development in the future. We may fail to identify new product opportunities and may not develop and bring new products to market in a timely manner. In addition, products or technologies developed by others may render our products or technologies obsolete or noncompetitive, or our targeted customers may not select our products for design or integration into their products. The failure of any of our new product development efforts could have an adverse effect on our business and financial results.

We have introduced RAID-enabled products based on the next generation SATA technology and delivered our products based on Serial Attached SCSI technology to certain major OEMs for testing and integration. We will not succeed in generating significant revenues from our new SATA and Serial Attached SCSI technology products if the market does not adapt to these new technologies, which would, over time, adversely affect our net revenues and operating results.

Our reliance on industry standards and technological changes in the marketplace may cause our net revenues to fluctuate or decline. The computer industry is characterized by various, evolving standards and protocols. We design our products to conform to certain industry standards and protocols such as the following:

Technologies:

• ATA

• Fibre channel

• FireWire/1394

• IPsec

• iSCSI

• PCI

• PCI-Express

• PCI-X

• RAID

• Serial Attached SCSI

• SATA

• SCSI

• SMI-S

• Ultra DMA

• USB

Operating Systems:

• Linux

• Macintosh

• Netware

• OS/2

• UNIX

• Windows

If user acceptance of these standards declines, or if new standards emerge, and if we do not anticipate these changes and develop new products, these changes could adversely affect our business and financial results.

If we lose the cooperation of other hardware and software producers whose products are integral to ours, our ability to sustain or grow our revenues could be adversely affected. We must design our products to operate effectively with a variety of hardware and software products supplied by other manufacturers, including the following:

• Microprocessors;

• Peripherals; and

• Operating system software.

We depend on significant cooperation from these manufacturers to achieve our design objectives and develop products that operate successfully with their products. These companies could, from time to time, elect to make it more difficult for us to design our products for successful operability with their products. For example, if one or more of these companies were to determine that as a result of competition or other factors our technology or products would not be broadly accepted by the markets we target, these companies may no longer work with us to plan for new products and new generations of our products, which would make it more difficult to introduce products on a timely basis or at all. Further, some of these companies might decide not to continue to offer products that are compatible with our technology and our markets could contract. If any of these events were to occur, our revenue could be adversely affected.

We are subject to various environmental laws and regulations that could impose substantial costs upon us and may adversely affect our business. The European Parliament has enacted the RoHS Directive, which restricts the sale of new electrical and electronic equipment containing certain hazardous substances, including lead that is currently used in some of the products we manufacture. We are working to modify our manufacturing processes to eliminate lead from our products in accordance with the timelines established in the RoHS Directive. This may require us to make additional capital expenditures. In addition, the costs associated with compliance may negatively impact our operating results and competitive position. For example, in the first nine months of fiscal 2006, we had an excess inventory adjustment of $1.9 million related to the transition of our products to comply with the RoHS Directive. We are also working with our suppliers to redesign or reformulate their components containing lead to reduce or eliminate lead in our products. If we are unable to comply with the RoHS Directive, we may suffer a loss of revenue, be unable to sell affected products in certain markets or countries and be at a competitive disadvantage.

We reorganized our business segments and have planned significant system enhancements and improvements, and these changes could adversely impact our business if not adequately managed and controlled. In the second quarter of fiscal 2006, we reorganized our internal organization structure related to our OEM and Channel segments. Where previously our former OEM and Channel segments each offered an integrated set of customer-focused products, the new organization is managed at the product level. The reorganization has placed demands on our management and our operational and financial infrastructure. In addition, management is in the process of enhancing our supply-chain systems and processes. These system enhancements and improvements require expenditures and allocation of management resources. If these improvements are not implemented successfully, our ability to manage our new organization could be impaired. In addition, we may be required to incur additional expenditures to address these issues, which could harm our financial position.

If we do not meet our restructuring objectives, we may have to implement additional plans in order to reduce our operating costs and may, as a result, incur additional material restructuring charges. We have implemented several restructuring plans to reduce our operating costs in the third quarter of fiscal 2006, fiscal 2005, fiscal 2004 and fiscal 2003, and recorded related restructuring charges of $2.6 million, $5.9 million, $4.3 million and $14.3 million, respectively. The plans included primarily the reduction of our workforce and the consolidation of our manufacturing operations in Singapore. The goals of these plans were to support future growth opportunities, focus on investments that grow revenues and increase operating margins. If we do not meet our restructuring objectives, we may have to implement additional restructuring plans to reduce our operating costs, which could cause us to incur material restructuring charges. Further, these restructuring plans may not achieve the goals we had in implementing them due to such factors as significant costs or restrictions on workforce reductions that may be imposed in some international locales and a potential adverse effect on employee morale that could harm our efficiency and our ability to act quickly and effectively in the rapidly changing technology markets in which we sell our products.

Some of our products contain “open source” software, and any failure to comply with the terms of one or more of these open source licenses could negatively affect our business. Some of our products are distributed with software licensed by its authors or other third parties under so-called “open source” licenses, including, for example, the GNU General Public License, or GPL, GNU Lesser General Public License, or LGPL, the Mozilla Public License, the BSD License, and the Apache License. Some of those licenses may require as a condition of the license that we make available source code for modifications or derivative works we create based upon, incorporating, or using the open source software, that we provide notices with our products, and/or that we license such modifications or derivative works under the terms of a particular open source license or other license granting third parties certain rights of further use. If an author or other third party that distributes such open source software were to allege that we had not complied with the conditions of one or more of those open source licenses, we could be required to incur legal expenses in defending against such allegations, and if our defenses were not successful we could be enjoined from distribution of the products that contained the open source software and required to either make the source code for the open source software available, to grant third parties certain rights of further use of our software, or to remove the open source software from our products, which could disrupt our distribution and sale of some of our products. In addition, if we combine our proprietary software with open source software in a certain manner, we could under some of the open source licenses, be required to release the source code of our proprietary software. If an author or other third party that distributes open source software were to obtain a judgment against us based on allegations that we had not complied with the terms of any such open source licenses, we could also be subject to liability for copyright infringement damages and breach of contract for our past distribution of such open source software.

Our operations depend on key personnel, the loss of whom could affect the growth and success of our business. In order to be successful, we must retain and motivate our executives, the general managers of

our business segments, our principal engineers and other key employees, including those in managerial, technical, marketing and information technology support positions. In particular, our product generation efforts depend on hiring and retaining qualified engineers. Competition for experienced management, technical, marketing and support personnel remains intense. For example, we transitioned certain research and development efforts to North Carolina, where we have experienced significant competition in our efforts to attract and retain qualified software engineers. The loss of any of these key employees could have a significant impact on our operations. We also must continue to motivate employees and keep them focused on our strategies and goals, which may be particularly difficult due to morale challenges posed by workforce reductions, the announcement of the divestiture of the systems business and general uncertainty.

Our international operations involve risks, and may be subject to political or other non-economic barriers to our being able to sell our products in certain countries, local economic conditions that reduce demand for our products among our target markets and potential disruption in the supply of necessary components. Many of our subcontractors are primarily located in Asia and we have sales offices and customers located throughout Europe, Japan and other countries. Our international operations and sales are subject to political and economic risks, including political instability, currency controls, changes in import/export regulations, tariffs and freight rates. In addition, because our primary wafer supplier, TSMC, is located in Taiwan, we may be subject to certain risks resulting from political instability in Taiwan, including conflicts between Taiwan and the People’s Republic of China. These and other international risks could result in the creation of political or other non-economic barriers to our being able to sell our products in certain countries, create local economic conditions that reduce demand for our products among our target market or expose us to potential disruption in the supply of necessary components or otherwise adversely affect our ability to generate revenue and operate effectively.

We depend on third parties to transport our products. We rely on independent freight forwarders to move our products between manufacturing plants and our customers. Any transport or delivery problems because of their errors, or because of unforeseen interruptions in their activities due to factors such as strikes, political instability, terrorism, natural disasters and accidents, could adversely affect our business, financial condition and results of operations and ultimately impact our relationship with our customers.

If the carrying value of our long-lived assets is not recoverable, an impairment loss must be recognized which would adversely affect our financial results. Certain events or changes in circumstances would require us to assess the recoverability of the carrying amount of our long-lived assets. In the first nine months of fiscal 2006, we recorded a goodwill impairment charge of $90.6 million related to our DPS segment. In fiscal 2005, we recorded a goodwill impairment charge of $52.3 million related to our Channel segment. In fiscal 2004, we recorded an impairment charge of $5.0 million related to certain properties classified as held-for sale and a charge of $1.0 million relating to the decline in value of a minority investment. In fiscal 2003, we recorded an impairment charge of $1.5 million relating to the decline in value of minority investments. In fiscal 2002, we recorded impairment charges of $77.6 million relating to technology acquired in a prior acquisition and the decline in value of minority investments. We will continue to evaluate the recoverability of the carrying amount of our long-lived assets, and we may incur substantial impairment charges which could adversely affect our financial results.

If actual results or events differ materially from those contemplated by us in making estimates and assumptions, our reported financial condition and results of operations for future periods could be materially affected. 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 amounts reported in the consolidated financial statements and accompanying notes. For example, we have identified key accounting estimates in our Critical Accounting Policies in our Annual Report on Form 10-K for the fiscal year ended March 31, 2005, which includes revenue, inventory, goodwill and income taxes. In addition, Note 1 of the Notes to Consolidated Financial Statements in our

Annual Report on Form 10-K for the fiscal year ended March 31, 2005 describes the significant accounting policies essential to preparing our consolidated financial statements. The preparation of these financial statements requires estimates and assumptions that affect the reported amounts and disclosures. Although we believe that our judgments and estimates are appropriate and correct, actual future results may differ materially from our estimates.

If we are unable to protect and enforce our intellectual property rights, we may be unable to compete effectively. Although we actively maintain and defend our intellectual property rights, we may be unable to adequately protect our proprietary rights. In addition, the laws of certain territories in which our products are or may be developed, manufactured or sold, including Asia and Europe, may not protect our products and intellectual property rights to the same extent as the laws of the United States. Because we conduct a substantial portion of our operations in Singapore and other locations outside of the United States and sell to a worldwide customer base, we are more dependent on our ability to protect our intellectual property in international environments than would be the case if a larger portion of our operations were domestic.

Despite our efforts, we may be unable to prevent third parties from infringing upon or misappropriating our intellectual property, which could harm our business and ability to compete effectively. We have from time to time discovered counterfeit copies of our products being manufactured or sold by others. Although we have programs to detect and deter the counterfeiting of our products, significant availability of counterfeit products could reduce our revenues and damage our reputation and goodwill with customers.

Third parties may assert infringement claims against us, which may be expensive to defend and could divert our resources. From time to time, third parties assert exclusive patent, copyright and other intellectual property rights to our key technologies, and we expect to continue to receive such claims in the future. For example, in fiscal 2005, we, Nevada SCSI Enterprises, Inc. and Thomas A. Gafford (jointly, “NSE”) entered into a license and release agreement, pursuant to which we paid NSE $1.7 million as a one-time, fully paid-up license fee to settle NSE’s claims that some of our products infringed certain patents. In addition, we entered into a patent cross-license agreement with IBM in May 2000. Under this agreement, which was amended in March 2002, we received a release from infringement claims prior to January 1, 2000 and received the right to use certain of IBM’s patents through June 30, 2007. In consideration, we paid, in annual installments, an aggregate patent fee of $13.3 million through June 30, 2004. The risks of our receiving additional claims from third parties may be enhanced in periods such as the one that we are currently entering where we are beginning to offer product lines employing new technologies relative to our existing products.

We cannot assure you that third parties will not assert other infringement claims against us, directly or indirectly, in the future, that assertions by third parties will not result in costly litigation or that we would prevail in such litigation or be able to license any valid and infringed intellectual property from third parties on commercially reasonable terms. These claims may be asserted in respect of intellectual property that we own or that we license from others. In addition to claims brought against us by third parties, we may also bring litigation against others to protect our rights. Intellectual property litigation, regardless of the outcome, could result in substantial costs to us and diversion of our resources, and could adversely affect our business and financial results.

We may be required to pay additional federal income taxes which could negatively affect our results of operations and financial position. On December 15, 2000, we received a statutory notice of deficiency from the IRS with respect to our Federal income tax return for fiscal 1997. We filed a Petition with the United States Tax Court on March 14, 2001, contesting the asserted deficiencies and settlement agreements have been filed with the United States Tax Court on all but one issue. In addition, the IRS is currently auditing our Federal income tax returns for fiscal 1998 through fiscal 2003. We have resolved all issues for fiscal

1998 through fiscal 2001 other than the rollover impact of any potential resolution on the remaining fiscal 1997 issue and tax credits that were generated but not used in subsequent years that may be carried back. While we believe we have meritorious defenses against the asserted deficiencies and any proposed adjustments, and that sufficient taxes have been provided, we cannot predict the final outcome of these matters, and the final resolution could adversely affect our results of operations and financial position.

We may be engaged in legal proceedings that could cause us to incur unforeseen expenses and could occupy a significant amount of our management’s time and attention. From time to time we are subject to litigation or claims that could negatively affect our business operations and financial position. Such disputes could cause us to incur unforeseen expenses, could occupy a significant amount of our management’s time and attention, and could negatively affect our business operations and financial position.

We have in the past financed a portion of our capital expenditure needs from capital market financing, and if we need to seek additional financing, it may not be available on favorable terms. In order to finance strategic acquisitions, capital asset acquisitions and other general corporate needs, we have in the past relied, in part, on the capital markets. Historically, we have been able to access capital markets, but this does not necessarily guarantee that we will be able to access these markets in the future or at terms that are acceptable to us. The availability of capital in these markets is affected by several factors, including geopolitical risk, the interest rate environment and the condition of the economy as a whole. In addition, our own operating performance, capital structure and expected future performance impacts our ability to raise capital. For example, in the third quarter of fiscal 2006, Standard and Poor’s Ratings Services downgraded our subordinated debt rating from B- to CCC+. We believe that our current cash, cash equivalents, short-term investments and future cash provided by operations will be sufficient to fund our needs for at least the next twelve months. However, if our operating performance falls below expectations, we may need additional funds, which may not be available on favorable terms, if at all.

We are exposed to fluctuations in foreign currency exchange rates. Because a significant portion of our business is conducted outside the United States, we face exposure to adverse movements in non-United States currency exchange rates. These exposures may change over time as business practices evolve and could have an adverse impact on our financial results and cash flows. Historically, our exposures have related to non-dollar-denominated operating expenses in Europe and Asia. We began Euro-denominated sales to our distribution customers in the European Union in the fourth quarter of fiscal 2003. Additionally, we purchase a substantial portion of our raw materials and manufacturing equipment from foreign suppliers, and incur labor and other operating costs in foreign currencies, particularly in our Singapore manufacturing facility. An increase in the value of the dollar could increase the real cost to our customers of our products in markets outside the United States where we sell in dollars, and a weakened dollar could increase the cost of local operating expenses and procurement of raw materials to the extent we must purchase components in foreign currencies.

We hold minority interests in privately held venture funds, and if these venture funds face financial difficulties in their operations, our investments could be impaired. We continue to hold minority interests in privately held venture funds. At December 31, 2005, the carrying value of such investments aggregated $3.5 million. We have also committed to provide additional funding of up to $0.3 million. These investments are inherently risky because these venture funds invest in companies that may still be in the development stage or depend on third parties for financing to support their ongoing operations. In addition, the markets for the technologies or products of these companies are typically in the early stages and may never develop. If these companies do not have adequate cash funding to support their operations, or if they encounter difficulties developing their technologies or products, the venture funds’ investments in these companies may be impaired, which in turn, could result in impairment of our investment in these venture funds.

Our spin-off of Roxio Inc., which is now known as Napster Inc., may have potential subsequent tax liabilities that could negatively affect our results of operations. Pursuant to our distribution of the Roxio, Inc. common stock, we received an opinion from PricewaterhouseCoopers LLP, or PwC, regarding the tax-free nature of the transaction to us and to our stockholders under Section 355 of the Internal Revenue Code. The validity of the PwC opinion relating to the qualification of the distribution as a tax-free transaction is subject to factual representations and assumptions. We are not aware of any facts or circumstances that would cause such representations and assumptions to be untrue. In addition, the opinion of PwC is not binding on the IRS. If Napster or we fail to conform to the requirements set forth in the IRS regulations, it could cause the distribution to be taxable to us and to our stockholders, and our financial results could be adversely affected.

We may have potential business conflicts of interest with Roxio, which is now known as Napster, with respect to our past and ongoing relationships, and we may not resolve these conflicts on terms favorable to us. Conflicts of interest may arise between Napster and us in areas relating to our past and ongoing relationship, including tax, indemnification and other matters arising from the separation. These and other business conflicts could adversely affect the growth of our business in the future.

Changes in securities laws and regulations have increased and may continue to increase our costs. Changes in the laws and regulations affecting public companies, including the provisions of the Sarbanes-Oxley Act of 2002 and rules promulgated by the Securities and Exchange Commission, have increased and may continue to increase our expenses as we evaluate the implications of these rules and devote resources to respond to their requirements. In particular, we incurred additional administrative expense to implement Section 404 of the Sarbanes-Oxley Act, which requires management to report on, and our Independent Registered Public Accounting Firm to attest to, our internal control over financial reporting.

In addition, The Nasdaq National Market, on which our common stock is listed, has also adopted comprehensive rules and regulations relating to corporate governance. These laws, rules and regulations have increased and will continue to increase the scope, complexity and cost of our corporate governance, reporting and disclosure practices. We also expect these developments to make it more difficult and more expensive for us to obtain director and officer liability insurance in the future, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. Further, our board members, Chief Executive Officer and Chief Financial Officer could face an increased risk of personal liability in connection with the performance of their duties. As a result, we may have difficultly attracting and retaining qualified board members and executive officers, which would adversely affect our business.

Internal control deficiencies or weaknesses that are not yet identified could emerge. Over time we may identify and correct deficiencies or weaknesses in our internal control over financial reporting and, where and when appropriate, report on the identification and correction of these deficiencies or weaknesses. However, the internal control procedures can provide only reasonable, and not absolute, assurance that deficiencies or weaknesses are identified. Deficiencies or weaknesses that are not yet identified could emerge, and the identification and corrections of these deficiencies or weaknesses could have a material impact on our results of operations.

Internal control issues that appear minor now may later become material weaknesses. We are required to publicly report on deficiencies or weaknesses in our internal control over financial reporting that meet a materiality standard as required by law. Management may, at a point in time, accurately categorize a deficiency or weakness as immaterial or minor and therefore not be required to publicly report such deficiency or weakness. Such determination, however, does not preclude a change in circumstances such that the deficiency or weakness could, at a later time, become a material weakness that could have a material impact on our results of operations.

We may encounter natural disasters, which could cause disruption to our employees or interrupt the manufacturing process for our products. Our operations could be subject to natural disasters and other

business disruptions, which could seriously harm our revenues and financial condition and increase our costs and expenses. Our corporate headquarters are located in California, near major earthquake faults. Additionally, our primary wafer supplier, TSMC, is located in Taiwan, which has experienced significant earthquakes in the past. A severe earthquake could cause disruption to our employees or interrupt the manufacturing process, which could affect TSMC’s ability to supply wafers to us, which would negatively affect our business and financial results. The ultimate impact on us and our general infrastructure of being located near major earthquake faults is unknown, but our net revenues and financial condition and our costs and expenses could be significantly impacted in the event of a major earthquake.

Manmade problems such as computer viruses or terrorism may disrupt our operations and harm our operating results. Despite our implementation of network security measures, our servers are vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems. Any such event could have an adverse effect on our business, operating results, and financial condition. In addition, the effects of war or acts of terrorism could have an adverse effect on our business, operating results, and financial condition. In addition, as a company with headquarters and significant operations located in the United States, we may be impacted by actions against the United States. We are predominantly uninsured for losses and interruptions caused by terrorist acts and acts of war.

We may experience significant fluctuations in our stock price, which may, in turn, significantly affect the trading price of our convertible notes. Our stock has experienced substantial price volatility, particularly as a result of quarterly variations in our operating results, the published expectations of analysts and as a result of announcements by our competitors and us. In addition, the stock market has experienced price and volume fluctuations that have affected the market price of many technology companies, in particular, and that have often been unrelated to the operating performance of such companies. In addition, the price of our securities may also be affected by general global, economic and market conditions and the cost of operations in one or more of our product markets. While we cannot predict the individual effect that these factors may have on the price or our securities, these factors, either individually or in the aggregate, could result in significant variations in the price of our common stock during any given period of time. These fluctuations in our stock price also impact the price of our outstanding convertible securities and the likelihood of the convertible securities being converted into our common stock.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For financial market risks related to changes in interest rates, equity price and foreign currency exchange rates, reference is made to Item 7A “Quantitative and Qualitative Disclosures About Market Risk” contained in Part II of our Annual Report on Form 10-K for the fiscal year ended March 31, 2005. Our exposure to market risk has not changed materially since March 31, 2005.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer (CEO) and our Chief Financial Officer (CFO), we conducted an evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (Exchange Act), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based upon that evaluation, our CEO and our CFO have concluded that the design and operation of our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

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