Restatement of Condensed Consolidated Financial Statements

Restatement of Previously Issued Financial Statements

In this Form 10-Q, the Company is restating its condensed consolidated balance sheet as of September 30, 2005, the related consolidated statements of
operations for the three and nine months ended June 30, 2005, and the related consolidated statement of cash flows for the nine months ended June 30, 2005 as a result of an independent stock option investigation commenced by the Special
Committee of the Board of Directors.

The Special Committee Investigation

On July 18, 2006 and July 26, 2006, two purported shareholder derivative actions were filed against certain of the Companys current and
former directors and officers alleging that the Companys historical stock option granting practices from 1995 through 2002 violated federal and state law. In response to these lawsuits, management conducted a preliminary review of the
Companys historical stock option granting practices.

On August 8, 2006, based on this review, the Board of Directors
established the Special Committee, composed of two independent directors, to review the Companys historical stock option practices and related accounting. The Special Committee was charged with reviewing managements practices related to
all stock option grants made by the Company during the review period, and examining the conduct of its current and former directors, officers, and employees involved in the option grant process.

The Board of Directors, with the concurrence of the Special Committee, determined that, pursuant to the requirements of APB 25, the actual measurement
dates for financial accounting purposes of certain stock options granted primarily during fiscal years 1997-2005 differed from the recorded grant dates of such awards, and that revised measurement dates for financial accounting purposes would apply
to the affected awards, which would result in additional and material non-cash stock-based compensation expense.

The Special Committees Review Process

The Special Committee reviewed the facts and circumstances surrounding all stock option grants made during the period from January 1, 1997 through
July 2006 (the Review Period) as well as grants dated October 13, 1995 and November 8, 1996, which were identified in the derivative complaints, for a total of 104 grant dates. The Special Committee held sixteen meetings
and interviewed 20 individuals, including current and former employees of ISSI, officers and directors, and outside counsel. In addition, the Company evaluated all grants in 1995 and 1996 since the date of the Companys initial public offering
and concluded that any possible additional errors arising from grants made during this time would not be material to the financial statements included in this Form 10-Q.

The Special Committee also reviewed the facts and circumstances surrounding the potential backdating of cash and cash-less exercises of options. The Company considered whether the cash-less exercises or cash exercises
had any accounting consequences such as potential compensation charges and additional income tax deductions. For cash-less exercises, the exercise process utilized a third party broker so there was little chance for exercise date manipulation. For
cash exercises, the Special Committee determined that the existing evidence and information available are inconclusive. Had there been backdating of cash exercises, the potential maximum exposure of the compensation charge representing tax benefits
forgone by the Company using fixed plan accounting, together with any underreported taxes would not be material for any fiscal period.

Findings of the
Special Committees Review

From the beginning of the Review Period through December 2005, the Company did not consistently follow
its option grant procedures. Of the 104 grants under review, the Special Committee was unable to find sufficient contemporaneous documentation to support the original measurement date for 73 grant dates. The Special Committee did find documentation
to support the original measurement date for the remaining 31 grant dates, and because the accounting treatment for these grants is correct, they are not included in the accounting adjustment.

The 73 grant dates for which there was insufficient evidence to support the original grant date were further placed into one of three sub-categories:



| |  |  | Backdated. There are eight grant dates for which there is conclusive evidence that the original measurement date was selected retroactively. On these eight
grant dates, the Company granted options for approximately 3.0 million shares. The associated compensation charge through Fiscal Year 2005 is approximately $12.7 million.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Appears Misdated. There are 55 grant dates which resemble Backdated grants in that they were made on dates when the stock price was comparatively low, the
grants were added to the Companys Equity Edge database (i.e., the software system the Company used to record stock option data) a significant amount of time after the purported date of grant, and meta-data from documents such as minutes or
resolutions indicates that these documents were created after the purported grant date. These grant dates differ from Backdated grants in that there is no email or testimonial evidence to directly support the inference that the grant dates were
selected retroactively. On these 55 grant dates, the Company granted options for approximately 10.9 million shares. The associated compensation charge is approximately $16.5 million through Fiscal Year 2005.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Appears Misdated/No Accounting Impact. There are ten grant dates that follow the same pattern as the Appears Misdated grants, but because the stock price on
the revised measurement date is lower than the stock price on the original measurement date, the Company will not recognize compensation expense on these misdated grants. On these ten grant dates, the Company granted options for approximately
2.3 million shares.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

After consideration of the accounting literature and recent guidance from the SEC staff, the
Company has organized the grants during the relevant period into categories based on grant type and the process by which the grant was finalized. The Company analyzed the evidence from the Special Committees investigation related to each
category including, but not limited to, physical documents, electronic documents, underlying electronic data about documents, and witness interviews.

Based on the relevant facts and circumstances, the Company applied the then appropriate accounting standards to determine, for every grant within each
category, the proper measurement date. If the measurement date was not the originally assigned grant date, accounting adjustments were made as required, resulting in stock-based compensation expense and related tax effects.

The following summarizes the Companys findings by type of grant:

Board of Director Grants. Outside directors receive option grants automatically pursuant to the Director Plan, which provides that the first grant occurs on the date a person becomes a director. Grants recur
automatically on the date each director is re-elected by shareholders. Grants were made to outside directors on 15 dates in the Review Period. The Company discovered one discrepancy and recorded $2,350 in stock compensation charges.

Officer Grants. Awards of option grants to executive officers (as defined in Section 16 of the Securities Exchange Act of 1934) were made
either by the Board of Directors as a whole, or by the Compensation Committee of the Board, which was comprised of non-management directors. Grants to executive officers were memorialized and approved in minutes of Board meetings or in documents
signed by our Compensation Committee. The Compensation Committee determined a specific number of stock options and salary compensation to officers, but delegated in a de facto manner its authority to select the grant dates and exercise prices to the
former Chief Financial Officer, Gary L. Fischer, including at times when he was not a member of the Board of Directors. The Compensation Committee thereafter authorized the grants, without knowledge of how Mr. Fischer selected the grant dates
or prices. The Company has concluded that the authorization by the Compensation Committee was perfunctory and therefore could not be relied upon to determine the grant date. Grants to executive officers were made on 21 dates and include
approximately 2.4 million shares. Four grants were categorized as Backdated, seven grants were categorized as Appears Misdated, and ten of these grant dates were categorized as Correct. The ten grants categorized as correct had original
measurement dates that were deemed appropriate based upon various contemporaneous documentation that indicated that the exercise price and the number of options granted to individual recipients were known with finality at the original measurement
dates. The associated compensation charge is approximately $3.4 million through Fiscal Year 2005.

Non-executive Employee Grants (New
Hire, Follow-on, and Bonus). Option grants awarded to employees who were not then executive officers (as defined in Section 16 of the Securities Exchange Act of 1934) were memorialized and approved in documents signed by the Stock Option
Committee, pursuant to authority delegated by the Board of Directors. The Stock Option Committee was made up of the Chief Executive Officer and a non-management director. The Special Committee concluded that the Stock Option Committee delegated in a
de facto manner its authority to select the grant dates and exercise prices to the former Chief Financial Officer, Gary L. Fischer, including at times when he was not a member of the Board of Directors. The quantity of shares granted were typically
based on salary range guidelines set by the Company and approved by the Stock Option Committee. The Stock Option Committee thereafter authorized the grants, without knowledge of how Mr. Fischer had selected the grant dates or prices. The
Company has concluded that the authorization by the Stock Option Committee was perfunctory and therefore could not be relied upon to determine the grant date. Grants to non-executive employees were made on 76 dates during the Review Period, and
totaled approximately 13.6 million shares. Grants on six dates were categorized as Backdated and 52 grant dates were categorized as Appears Misdated, representing approximately 10.2 million shares. The associated compensation charge is
approximately $21.5 million through Fiscal Year 2005. In addition, ten grants were categorized as Appears Misdated/No Accounting Impact and eight grants were categorized as Correct, representing approximately 3.4 million shares. The eight
grants categorized as correct had original measurement dates that were deemed appropriate based upon various contemporaneous documentation that indicated that the exercise price and the number of options granted to individual recipients were known
with finality at the original measurement dates.

Salary Reduction Grants. The Company granted options to officers and employees in
connection with five salary reduction programs. Three of these grant dates were categorized as Backdated (representing 535,716 shares) and two grant dates were categorized as Appears Misdated (representing 254,965 shares). These totals exclude any
grants to officers, as they were previously included in the Officer Grant totals. The associated compensation charge is approximately $2.2 million through Fiscal Year 2005.

Stock Option Re-pricing Grants. The Company granted options to officers and employees four times in connection with stock option re-pricing
programs. On October 13, 1995, the Company granted 699,000 options (excluding options to



7

(unaudited)



officers); this grant was categorized as Correct. On December 6, 1996 the Company granted 75,000 options to officers and on December 27, 1996 the
Company granted 847,000 options to employees; both of these grants, which were outside of the Review Period, have been determined to be Correct by the Company. On December 2, 1998, the Company granted 1,622,418 options (excluding options to
officers); this grant was categorized as Appears Misdated (the appropriate measurement date was determined to be December 11, 1998). These re-pricing grants predated the adoption of FIN 44 and the Company applied EITF Issue No. 87-33,
Stock Compensation Issues Related to Market Decline (EITF Issue No. 87-33). The associated fixed compensation charge is approximately $2.1 million through Fiscal Year 2005. During the investigation, the Company identified that 232,050 options
granted, all to non-officers, in the December 1998 re-pricing, represented options re-priced a third time and are being considered variable awards under EITF 87-33. The Company has recorded the related charges of approximately $2.3 million over the
Review Period as part of this restatement.

Consultant Grants. During the Review Period, the Company made one grant to a consultant
that was not properly recorded. A total of 25,000 shares were granted on March 23, 1998 which was the date of the consulting contract. Compensation expense of $74,000 was recorded during the year ended September 30,1998 as per FASBs
Emerging Issues Task Force Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services (EITF 96-18).

Modification of Grants.There were 20 option grants which were modified between the periods of 1997 to 2003 to have the exercise period extended.
Under Financial Interpretation No. 44, Accounting for Certain Transactions involving Stock Compensation, an interpretation of APB Opinion No. 25, the Company has recorded additional compensation expense for the modification of these
option grants. The additional compensation charge for the affected options, calculated as the difference between the intrinsic value on the award date and the intrinsic value on the modification date, amounted to $440,000.

Consideration for Revised Measurement Dates

The
Company identified two types of fact patterns regarding the available evidence regarding grants made during the Review Period. In Fact Pattern One, the Company found documentation to identify a specific date on which the grantees, the number of
shares, and the prices of the options were known and support the original measurement date. Grants falling within this first fact pattern are primarily grants to directors and officers. Options granted from February 2006 onward also fall within this
category, because at that time, the Company instituted new procedures for granting stock options. These procedures require contemporaneous documentation of the date of grant. The 31 grants in this category did not require revised measurement dates.

In Fact Pattern Two, for most grants in the Review Period, it is not possible to ascertain with certainty from the available evidence when
the list of grantees was final. For these 73 grants, there was insufficient contemporaneous evidence related to the Original Measurement Date. For four grants in this category, contemporaneous evidence exists to support a revised measurement date

Based on the evidence, the Company has concluded that it should consider all available evidence to determine the earliest date that the
terms of options to individual recipients were known with finality for all grants which fall into the categories Backdated, Appears Misdated and Appears Misdated/No Accounting Impact (other than for FAS 123 Pro Forma purposes), for purposes of
selecting the Revised Measurement Dates. For the vast majority of grants, the Company has concluded, based on all available evidence, that the Equity Edge Record Added Date is the earliest date when the terms of options to individual recipients were
known with finality and therefore that is the Revised Measurement Date. Alternative measurement dates were used when other documentary evidence exists to support such dates such as dated Unanimous Written Consents, or in the case of a grant to a new
director, the date of commencement of service. Alternative methods for determining revised measurement dates were used on four grants as the documentary evidence for the grants either identified with certainty the date the terms of the option to
individual recipients were known with finality or supported, when uncertainty remains, a date earlier than the Equity Edge entry date.

The
Equity Edge Record Added date represents a contemporaneous, fixed, identifiable date in the option grant process, which evidences that the Company had incurred a legal obligation to the employee-recipient and that the criteria listed in Paragraph
10(b) of APB 25 were met. There is significant evidence that the terms of the grants were final by the



8

(unaudited)



time they were entered into Equity Edge. Furthermore, based on the lack of verifiable contemporaneous documentation, the Equity Edge Record Added date
represents the earliest determinable date as of which the criteria listed in Paragraph 10(b) of APB 25 were met, as both the exercise price and the number of options granted to each individual were known on that date. Based on the apparent practice
utilized by Mr. Fischer to grant stock awards using hindsight, the Company believes that the APB 25 criteria were not met at the earlier stated grant date, and it is likely that the exercise price was not established until a point close to the
Equity Edge Entry Date.

Financial Impact of the Adjustments to the Measurement Dates

Based on the results of the equity award review, the Company concluded that, pursuant to APB 25, and related interpretations, the accounting measurement
dates for most of the stock option grants awarded between 1995 through 2005, covering options to purchase 19.3 million shares of our common stock, differed from the measurement dates previously used for such awards. As a result, revised
measurement dates were applied to the affected option grants and the Company recorded a total of $29.2 million in additional non-cash stock-based compensation expense for the years 1997 through 2005. Of the $29.2 million, $25.6 million utilized the
equity edge entry dates. This amount is net of forfeitures related to employee terminations. The additional stock-based compensation expense is being amortized over the service period relating to each option which is typically four years.

Stock Option grants that were intended to qualify as Incentive Stock Options (ISOs) under the Internal Revenue Code but were
granted in-the-money as described above would not receive the favorable tax treatment under the ISOs. As such, the employer and employee portions of certain payroll tax amounts were not appropriately withheld when the options were
exercised. Had the Company recorded these expenses as they occurred, then the Company would have recognized an additional tax expense of $368,000 over the period. The Company intends to enter into settlement discussions with the Internal Revenue
Service in June 2007 regarding this matter for those tax years which are still open with the IRS: 2004, 2005, and 2006. Based on the Companys assessment, the payroll tax and withholding liability is approximately $13,000 for those periods. The
Company intends to pay the amounts including the amounts on behalf of the employees. The Company is recording charges for each year in which the payroll tax should have been assessed, and then reversing that charge in the fiscal year when the
statute of limitations expires. These charges have been recorded in the financial statements as compensation cost.

In the Companys
restatements for fiscal years 1997 to 2003 and 2005, no adjustments were made to the originally reported income tax provision or benefit resulting from the additional stock-based compensation expenses. No tax benefits were recorded for additional
stock-based compensation for these years since such amounts were offset by valuation allowances which would not be realized given the existence of operating losses and lack of earnings history. In the Companys restatement for fiscal year 2004,
a $52,000 reduction to the amount of originally reported tax provision was recorded to reflect the tax benefits that the additional stock-based compensation had to the federal alternative minimum tax expense.

3. Reclassifications

Certain reclassifications have been made to prior period balances in order to conform to the current periods presentation. In particular, accounts receivable, net has been increased by $1.0 million and accrued
liabilities has been increased by $1.0 million as of September 30, 2005 and property, equipment and leasehold improvements has been increased by $1.9 million and other assets has been decreased by $1.9 million.

4. Use of Estimates

The preparation of
financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent
assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates, and such differences, may be material to the
financial statements.

5. Impact of Recently Issued Accounting Standards

In May 2005, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 154, Accounting
Changes and Error Corrections (SFAS 154) which replaces Accounting Principles Board Opinion (APB) No. 20 Accounting Changes and SFAS No. 3, Reporting Accounting Changes in Interim Financial StatementsAn
Amendment of APB Opinion No. 28. SFAS 154 provides guidance on the accounting for and reporting of accounting changes and error corrections. It establishes retrospective application, or the latest practicable date, as the required
method for reporting a change in accounting principle and the reporting of a correction of an error. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005 and is
required to be adopted by the Company in the first quarter of fiscal 2007. The Company does not expect the adoption of SFAS 154 will have a material impact on its consolidated results of operations and financial position.

In June 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxesan interpretation of FASB
Statement No. 109. The interpretation contains a two step approach to recognizing and measuring uncertain tax positions accounted for in accordance with SFAS No. 109. The first step is to evaluate the tax position for recognition by
determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit
as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The provisions are effective for the Company beginning in the first quarter of fiscal 2008. The Company is currently evaluating the impact this statement
will have on its consolidated financial statements.

In September 2006, the Securities and Exchange Commission (SEC) issued Staff Accounting
Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (SAB 108). SAB 108 gives guidance on how errors, built up over time in the balance sheet,
should be considered from a materiality perspective and corrected. SAB 108 provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement.
SAB 108 is effective for fiscal years ending after November 15, 2006, and early application is encouraged. The Company is currently evaluating the impact that the provisions will have on the Companys consolidated balance sheet and
statement of operations.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS
No. 157) which establishes a framework for measuring fair value and enhance disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. The measurement and disclosure requirements
are effective for the Company beginning in the first quarter of fiscal 2009. The Company is currently evaluating whether SFAS No. 157 will result in a change to its fair value measurements.

In September 2006, the FASB issued SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement
PlansAn Amendment of FASB Statements No. 87, 88, 106, and 132R (SFAS No. 158). SFAS No. 158 requires that the funded status of defined benefit postretirement plans be recognized on the Companys balance sheet, and
changes in the funded status be reflected in comprehensive income, effective fiscal years ending after December 15, 2006. SFAS No. 158 also requires the measurement date of the plans funded status to be the same as the Companys
fiscal year-end. This requirement is not required until fiscal 2008. The Company is currently evaluating the impact that the provisions will have on the Companys consolidated balance sheet and statement of operations.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS No. 159)
which permits companies to choose to measure certain financial instruments and certain other items at fair value. The standard requires that unrealized gains and losses on items for which the fair value option has been elected be reported in
earnings. SFAS 159 is effective for the Company beginning in the first quarter of fiscal 2009, although earlier adoption is permitted. The Company is currently evaluating the impact SFAS No. 159 will have on its consolidated financial
statements.

6. Stock-based Compensation

The Company has stock option plans under which options to purchase shares of the Companys common stock may be granted to employees and directors. At June 30, 2006, the total number of shares subject to options outstanding under
all plans was 5,979,000. At June 30, 2006, 2,809,000 shares were available for grant under all plans. Options generally vest ratably over a four-year period with a 6-month or 1-year cliff vest and then vesting ratably over the remaining period.
Options granted prior to September 30, 2005 expire ten years after the date of grant; options granted after October 1, 2005 expire seven years after the date of the grant.

As approved by the Board of Directors, effective February 1, 2006, future offering periods under the Companys employee stock purchase plan
(ESPP) will have a duration of six months and the purchase price will be equal to 85% of the fair value of the Companys common stock on the purchase date. Previously, the Companys ESPP permitted eligible employees to purchase common
stock through payroll deductions at a price equal to 85% of the lesser of the fair value of the Companys common stock as of the first day of the 24-month offering period or the last day of each six-month purchase period. The offering periods
under the ESPP commence on approximately February 1 and August 1 of each year. At June 30, 2006, 1,177,000 shares were available for issuance under the ESPP.

Adoption of SFAS 123R

Beginning in fiscal 2006, the Company accounts for stock-based
compensation arrangements in accordance with the provisions of SFAS No. 123(R) Share-Based Payment (SFAS 123R). Under SFAS 123R, compensation cost is calculated



15

(unaudited)



by the Company on the date of grant using the fair value of the option as determined using the Black-Scholes method. The compensation cost is then amortized
ratably over the vesting period of the individual option grants. The Black-Scholes valuation calculation requires the Company to estimate key assumptions such as expected term, volatility and interest rates to determine the fair value of the stock
options. The estimate of these key assumptions is based on the Companys historical stock price volatility, employees historical exercise patterns and judgment regarding market factors and trends. SFAS 123R also requires that forfeitures
be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates forfeitures based on its historical forfeiture rates as it believes these rates to be the
most indicative of the Companys expected forfeiture rate.

The Company adopted the fair value recognition provisions of SFAS 123R
using the modified prospective transition method. Under the modified prospective transition method, prior periods are not restated for the effect of adopting SFAS 123R. Commencing with the first quarter of fiscal 2006, compensation cost includes all
share-based awards granted prior to, but not yet vested as of October 1, 2005, based on the grant date fair value estimated in accordance with the original provisions of SFAS 123, and compensation for all share-based awards granted subsequent
to October 1, 2005, based on the grant date fair value estimated in accordance with the provisions of SFAS 123R.

As a result of
adopting SFAS 123R on October 1, 2005, the Company recorded stock-based compensation expense of $0.9 million and $3.6 million, in the three and nine month periods ended June 30, 2006, respectively. The impact of adopting SFAS 123R resulted
in an increase to the Companys net loss per share of $0.02 and $0.10 for the three and nine months ended June 30, 2006, respectively. As of June 30, 2006, there was approximately $10.7 million of total unrecognized stock-based
compensation expense net of estimated forfeitures of $2.1 million related to share-based payments awards under the Companys stock option plans that will be recognized over a weighted-average period of approximately 2.8 years. Future stock
option grants will add to this total whereas quarterly amortization and the vesting of the existing stock option grants will reduce this total. The Company will also record compensation expense for its ESPP for the difference between the purchase
price and the fair market value on the day of purchase.

Prior to the adoption of SFAS 123R, the Company presented all tax benefits
resulting from the exercise of stock options as operating cash flows in its Statement of Cash Flows. SFAS 123R requires that these cash flows be classified as financing cash flows. As the Company has a valuation allowance for all of its deferred tax
assets, a tax benefit associated with stock option exercises has not been recognized.

During the three and nine months ended June 30,
2006, options to purchase 56,000 shares and 196,000 shares, respectively, were exercised at an aggregate intrinsic value of $178,000 and $559,000, respectively, determined as of the date of option exercise.

Prior to Adoption of SFAS 123R

Prior to
October 1, 2005, the Company accounted for stock options under the recognition and measurement provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees (APB 25), and related Interpretations, as permitted by
SFAS Statement No. 123, Accounting for Stock-Based Compensation (SFAS 123). The Company provided the disclosures required under SFAS 123 as amended by SFAS No. 148, Accounting for Stock-Based Compensation 
Transition and Disclosures. The Company generally did not recognize stock-based compensation expense in its statement of operations for periods prior to the adoption of SFAS 123R except when options were granted at an exercise price lower than
the market value of the underlying common stock on the date of grant.

per share as if the Company had applied the fair value recognition provisions of SFAS 123R to options granted under the Companys stock-based compensation plans prior to its adoption of SFAS 123R. For purposes of this pro forma disclosure, the
value of the options was estimated using a Black-Scholes option-pricing formula and amortized on a straight-line basis over the respective vesting periods. Disclosures for the three and nine month periods ended June 30, 2006 are not presented
because stock-based payments were accounted for under SFAS 123Rs fair-value method during this period and included in the determination of net loss.

Valuation Assumptions

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option valuation model with the following weighted-average assumptions:



|                        |  |                           |   |  |                          |   |  |      |   |  |      |

|                        |  | Three MonthsEndedJune 30, |   |  | Nine MonthsEndedJune 30, |  
|                        |  | 2006                      |   |  | 2005                     |   |  | 2006 |   |  | 2005 |  
|Expected term in years  |  | 4.54                      |   |  | 2.75                     |   |  | 4.53 |   |  | 2.75 |  
|Estimated volatility    |  | 67                        | % |  | 69                       | % |  | 69   | % |  | 73   | %
|Risk-free interest rate |  | 4.96                      | % |  | 3.72                     | % |  | 4.50 | % |  | 3.45 | %
|Dividend yield          |  | 0.00                      | % |  | 0.00                     | % |  | 0.00 | % |  | 0.00 | %

The Company utilizes the simplified calculation of expected life under the provisions of the
SECs Staff Accounting Bulletin 107, as the Company shortened the contractual life of employee stock options from ten years to seven years. Estimated volatilities are based on historical stock price volatilities of the period immediately
preceding the option grant that is equal in length to the options expected term. The Company believes that historical volatility is the best estimate of future volatility. The Company bases the risk-free interest rate on the implied yield
currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term. The Company has never paid dividends and does not anticipate doing so over the expected life of the options and therefore used 0% for dividend yield. The
weighted-average grant date fair value of options granted during the three and nine months ended June 30, 2006 was $3.61 and $3.70, respectively. The weighted-average grant date fair value of options granted during the three and nine months
ended June 30, 2005 was $2.91 and $3.35, respectively. The estimated fair value of the employee stock options is amortized to expense ratably over the vesting period of the individual option grants.

7. Concentrations of Credit Risk

In the three and
nine months ended June 30, 2006 and June 30, 2005, no single customer accounted for over 10% of net sales.

The Company sold its investment in E-CMOS in April 2006 for approximately $1.5 million which
resulted in a pre-tax gain of $0.3 million.

The Company sold approximately 77% of its investment in Signia in February 2006 for
approximately $4.6 million which resulted in a pre-tax gain of $2.2 million. As a result of the sale of the Signia shares, the Company reduced its ownership percentage to approximately 16%, or approximately $0.7 million, and effective March 2006
accounts for its investment in Signia on the cost basis. In prior periods, Signias financial position and results of operation were consolidated with the Companys financial statements. The deconsolidation of Signia did not have a
material impact on the Companys balance sheet and will not have a material effect on the Companys revenues or results of operations.

The Company has various deposits including deposits with suppliers for purchase guarantees and for customs clearance. These deposits are included in restricted assets.

11. Comprehensive Income (Loss)

Comprehensive income (loss) includes the Companys net loss as
well as other comprehensive income (loss). The Companys other comprehensive income (loss) consists of changes in cumulative translation adjustment and unrealized gains and losses on investments.

Comprehensive income (loss), net of taxes, was as follows:

There were no assets pledged as collateral for short-term debt or notes. The Company has
guaranteed the borrowings of Integrated Circuit Solution, Inc. (ICSI) under a line of credit with a bank in Taiwan for a maximum amount of approximately $4.9 million through January 2007. As of June 30, 2006, $3.1 million was outstanding under
this line of credit.

13. Income Taxes

The income tax provision for the three months and nine months ended June 30, 2006 consists primarily of foreign withholding taxes of $51,000 and $164,000, respectively. The income tax provision for the three months and nine months
ended June 30, 2005 consists of foreign withholding taxes of $9,000 and $26,000, respectively.

14. Net Loss Per Share

The diluted earnings per share calculations for the three months and nine months ended June 30, 2006 do not include approximately 362,000 and 426,000
potential common shares from outstanding stock options because their inclusion would be anti-dilutive. For the three months and nine months ended June 30, 2006, an additional 5,105,000 and 5,019,000 stock options were excluded from diluted
earnings per share by the application of the treasury stock method. For the three months and nine months ended June 30, 2005, approximately 597,000 and 751,000 potential common shares from outstanding stock options were excluded from the
calculation of diluted earnings per share because their inclusion would have been anti-dilutive. For the three months and nine months ended June 30, 2005, an additional 3,036,000 and 3,098,000 stock options were excluded from diluted earnings
per share by the application of the treasury stock method.

15. Commitments and Contingencies

Legal Proceedings

The Company is
subject to various legal proceedings and claims as discussed below. In addition, In the ordinary course of our business, the Company has been involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured
liability in any one or more of them. Although the outcome of these actions is not presently determinable, we believe that the ultimate resolution of these matters will not harm our business and will not have a material adverse effect on our
financial position, cash flows or results of operations. Litigation relating to the semiconductor industry is not uncommon, and we are, and from time to time have been, subject to such litigation. No assurances can be given with respect to
the extent or outcome of any such litigation in the future.

Shareholder Derivative Actions

On July 18, 2006 and July 26, 2006, two purported shareholder derivative actions were filed against certain current and former directors and
officers of ISSI in the United States District Court for the Northern District of California, entitled (1) Rick Tope v. Jimmy S.M. Lee, et al., Case No. C06-04387, and (2) Murray Donnelly v. Jimmy S.M. Lee, et al., Case No.
C06-04545. The complaints purport to assert claims against the individual defendants on behalf of ISSI for breach of fiduciary duty, violations of Section 10(b) of the Securities Exchange Act of 1934 (Exchange Act) and Rule 10b-5
promulgated thereunder, unjust enrichment, and restitution based upon our alleged stock option grant practices from 1995 through 2002. The Company is named solely as a nominal defendant. The complaints seek damages in an unspecified amount against
the individual defendants, disgorgement of stock options or proceeds, equitable relief, attorneys fees, and other unspecified relief. Pursuant to the parties stipulation, the Court consolidated the two derivative actions on
August 22, 2006, under the caption In re Integrated Silicon Solution, Inc. Shareholder Derivative Litigation, Master File No. C-06-04387 RMW.

Plaintiffs filed a consolidated shareholder derivative complaint on November 27, 2006, based upon the same underlying facts and circumstances alleged in the prior complaints. In addition to the claims asserted
and the relief sought in the original complaints, the consolidated complaint purports to assert claims against the individual defendants for aiding and abetting and violating Sections 14(a) and 20(a) of the Exchange Act and seeks an accounting. The
Company is again named solely as a nominal defendant.

On October 31, 2006, another purported shareholder derivative action was filed
against certain current and former directors and officers of ISSI in the Superior Court of California for the County of Santa Clara, entitled Alex Chuzhoy v. Jimmy S.M. Lee, et al., Case No. 1:06-CV-074031. The complaint purports to
assert claims against the individual defendants on behalf of ISSI for insider trading in violation of California Corporations Code Sections 25402 / 25502.5, breach of fiduciary duty including in connection with the alleged insider selling and
misappropriation, abuse of control, gross mismanagement, constructive fraud, corporate waste, unjust enrichment, and rescission, based upon the Companys alleged stock option grant practices from 1995 through 2002. The Company is named solely
as a nominal defendant. The complaint seeks damages in an unspecified amount against the individual defendants, an accounting, certain corporate governance changes, a constructive trust over the defendants stock options or proceeds, punitive
damages, attorneys fees, and other unspecified relief.

Plaintiffs in the state and federal derivative complaints will amend their
complaints after the Company concludes its financial restatement. Defendants intend to move to dismiss both the state and federal complaints.

Nasdaq
Delisting

On August 17, 2006, the Company received a letter from The NASDAQ Stock Market indicating that the Company was not
in compliance with the NASDAQ requirements for continued listing set forth in NASDAQ Marketplace Rule 4310(c)(14), and faces a possible delisting. On December 7, 2006, following a hearing before the Nasdaq Listing Qualifications Panel
(Panel), the Panel notified the Company that it would remain listed on Nasdaq subject to the filing by February 13, 2007 of all required restatements and delinquent periodic reports, communication with the Panel about the results of
the independent committees investigation, and compliance with all other requirements for continued listing on the

Nasdaq Stock Market. The Company also received letters from The NASDAQ Stock Market indicating that as a result of its failure to timely file its Form 10-K
for the fiscal year ended September 30, 2006, and its Form 10-Qs for the quarters ended December 31, 2006 and March 31, 2007, it was not in compliance with the NASDAQ requirements for continued listing set forth in NASDAQ
Marketplace Rule 4310(c)(14).

On January 19, 2007, the Nasdaq Listing and Hearing Review Council (Listing Council)
notified the Company that, pursuant to its discretionary authority, it had called for review the December 7, 2006 decision of the Panel and stayed any determinations to suspend the Companys securities from trading pending further action
by the Listing Council. On May 9, 2007, the Company was advised by the Listing Council that it would remain listed on NASDAQ if it concludes its restatement and files its delinquent required SEC filings by June 5, 2007.

SRAM Antitrust Litigation

Thirty-two
purported class action lawsuits were filed against the Company and other SRAM suppliers in various U.S. federal courts alleging violations of the Sherman Act, violations of state unfair competition laws, and unjust enrichment relating to the sale
and pricing of SRAM products. The U.S. lawsuits have been consolidated in a single federal court for coordinated pre-trail proceedings. The U.S. complaints seek treble damages for the alleged damages sustained by purported class members, in addition
to restitution, costs and attorneys fees, as well as an injunction against the allegedly unlawful conduct. Two purported class action lawsuits were filed against us and other SRAM suppliers in two Canadian courts alleging violation of the
Canadian Competition Act and unlawful conduct at common law. The Canadian complaints seek compensatory and punitive damages, in addition to declaratory relief, restitution, and costs. The Company is committed to defending itself against these
claims and has instructed its counsel to contest these actions vigorously. Given the preliminary stage of these proceedings and the inherent uncertainty in litigation, the Company is unable to predict the outcome of these suits. The final resolution
of these alleged violations of federal or state antitrust laws could have a material adverse effect on the Companys business, results of operations, or financial condition.

SRAM Antitrust Civil Investigative Demand

In May 2007, the Company received a civil
investigative demand (CID) from the Attorney General of the State of Florida. The CID is issued pursuant to the Florida Antitrust Act in the course of an official investigation to determine whether there is, has been, or may be a
violation of state or federal antitrust laws. Although not alleging any wrongdoing, the CID seeks documents and data relating to the Companys business. The Company intends to cooperate fully with the Attorney General of Florida in this
investigation. Because the investigation is at an early stage, the Company cannot predict the outcome of the investigation and its effect, if any, on its business.

Commitments to Wafer Fabrication Facilities and Contract Manufacturers

The Company issues purchase
orders for wafers to various wafer foundries. These purchase orders are generally considered to be cancelable. However, to the degree that the wafers have entered into work-in-process, as a matter of practice, it becomes increasingly difficult to
cancel the purchase order. As of June 30, 2006, the Company had approximately $15.4 million of purchase orders for which the related wafers had been entered into wafer work-in-process (i.e., manufacturing had begun).

18. Acquisition of ICSI

On January 25, 2005, the Company announced its intent to acquire the remaining 71% of
ICSI that the Company did not then own. On May 1, 2005, ISSI assumed control of ICSI and in accordance with generally accepted accounting principles began consolidating the financial results of ICSI with its own results. In the nine months
ended September 30, 2005, the Company purchased additional shares of ICSI for approximately $52.5 million, increasing its ownership percentage to approximately 83%. In the nine months ended June 30, 2006, the Company purchased additional
shares of ICSI for approximately $13.9 million, increasing its percentage ownership to approximately 97%.

The Companys decision to
acquire ICSI was driven by several considerations including the opportunity to enhance sales, the ability to reduce the combined companys operating expenses, obtain stronger purchasing power, expand sales channels, and enhance opportunities to
develop non-memory product lines.

The Company is accounting for the acquisition of ICSI as a step acquisition. The allocation of the
purchase price of ICSI includes both tangible assets and acquired intangible assets including both developed technology and in-process research and development (IPR&D). The excess of the purchase price over the fair value allocated to the net
assets is goodwill. The Company currently does not expect to receive a tax benefit for goodwill. The amounts allocated to IPR&D have been expensed as it was deemed to have no future alternative value.

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

Background

On January 25, 2005, we announced our intention to acquire ICSI. ICSI was a public company in Taiwan and traded on the Gre Tai
Securities Market (OTC). ICSI is a fabless semiconductor company whose principal products are DRAM and controller chips. Prior to this transaction, we owned approximately 29% of ICSI. In the nine months ended September 30, 2005, we purchased
additional shares of ICSI in the open market for approximately $52.5 million increasing our ownership percentage to approximately 83% at September 30, 2005. In the nine months ended June 30, 2006, we purchased additional shares of ICSI for
approximately $13.9 million increasing our ownership percentage to approximately 97% at June 30, 2006.

Our financial results for
fiscal 2006 and for fiscal 2005 beginning May 1, 2005 reflect accounting for ICSI on a consolidated basis. On May 1, 2005, we assumed effective control of ICSI and in accordance with generally accepted accounting principles we began
consolidating the financial results of ICSI with our results as of such date. Our financial results for fiscal 2005 through the period ended April 30, 2005 reflect accounting for ICSI on the equity basis and include our percentage share of the
results of ICSIs operations.

In February 2006, we sold approximately 77% of our shares in Signia Technologies Inc. (Signia), a
developer of wireless semiconductors, thereby reducing our ownership percentage to approximately 16%. Effective March 1, 2006, we resumed accounting for Signia on the cost basis. During the period from December 1, 2004 through
February 28, 2006, our financial results reflect accounting for Signia on a consolidated basis. Our financial results through the period ended November 30, 2004 reflect accounting for Signia on the cost basis.

Our financial results for fiscal 2006 and for fiscal 2005 beginning May 1, 2005 reflect accounting for Key Stream Corp. (KSC), a semiconductor
company, on the equity basis. At June 30, 2006, we owned approximately 22% of KSC.

Overview

We are a fabless semiconductor company that designs and markets high performance integrated circuits for the following key markets: (i) digital
consumer electronics, (ii) networking, (iii) mobile communications and (iv) automotive electronics. Our primary products are high speed and low power SRAM and low and medium density DRAM. We also design and market EEPROMs, SmartCards,
and controller chips for card reader-writers. We were founded in October 1988 and initially focused on high performance, low cost SRAM for PC cache memory applications. In 1997, we introduced our first low and medium density DRAM products. Prior to
fiscal 2003, our SRAM product family generated a majority of our

revenue. However, in 2001, the high-end networking and telecom markets slowed and this adversely impacted our SRAM revenue. During this period, we increased
our focus on the digital consumer electronics, mobile communications and automotive electronics markets. As a result of our success in the digital consumer electronics market, sales of our low and medium density DRAM products have increased
significantly and have represented a majority of our net sales in each year since fiscal 2003.

In order to limit and control our operating
expenses, in recent years we have reduced our headcount in the U.S. and transferred various functions to Taiwan and China. Our acquisition of ICSI was a key part of this strategy. We believe this strategy has enabled us to limit our operating
expenses while simultaneously locating these functions closer to our manufacturing partners and our customers. As a result of these efforts, we currently have significantly more employees in Asia than we do in the U.S. We intend to continue these
strategies going forward.

As a fabless semiconductor company, our business model is less capital intensive because we rely on third
parties to manufacture, assemble and test our products. Because of our dependence on third-party wafer foundries, our ability to increase our unit sales volumes depends on our ability to increase our wafer capacity allocation from current foundries,
add additional foundries and improve yields of good die per wafer.

The average selling prices of our SRAM and DRAM products are very
sensitive to supply and demand conditions in our target markets and have generally declined over time. While the average selling prices for certain of our products increased during the first three quarters of fiscal 2004, the average selling prices
for our products declined significantly in the fourth quarter of fiscal 2004. We experienced declines in the average selling prices for certain of our products in fiscal 2005 and the first nine months of fiscal 2006. We expect average selling prices
for our products to decline in the future, principally due to increased market competition and an increased supply of competitive products in the market. Any future decreases in our average selling prices would have an adverse impact on our revenue
growth rate, gross margins and operating margins. Our ability to maintain or increase revenues will be highly dependent upon our ability to increase unit sales volumes of existing products and to introduce and sell new products in quantities
sufficient to compensate for the anticipated declines in average selling prices of existing products. Declining average selling prices will adversely affect our gross margins unless we are able to offset such declines with commensurate reductions in
per unit costs or changes in product mix in favor of higher margin products.

Revenue from product sales to our direct customers is
recognized upon shipment provided that persuasive evidence of a sales arrangement exists, the price is fixed and determinable, title has transferred, collection of resulting receivables is reasonably assured, there are no customer acceptance
requirements and there are no remaining significant obligations. A portion of our sales is made to distributors under agreements that provide the possibility of certain sales price rebates and limited product return privileges. Given the
uncertainties associated with credits that will be issued to these distributors, we defer recognition of such sales until our products are sold by the distributors to their end customers. Revenue from sales to distributors who do not have sales
price rebates or product return privileges is recognized at the time our products are sold by us to the distributors.

We market and sell
our products in Asia, the U.S. and Europe and other locations through our direct sales force, distributors and sales representatives. The percentage of our sales shipped outside the U.S. was approximately 83% and 85% in the first nine months of
fiscal 2006 and fiscal 2005, respectively. We measure sales location by the shipping destination, even if the customer is headquartered in the U.S. We anticipate that sales to international customers will continue to represent a significant
percentage of our net sales. The percentages of our sales by region are set forth in the following table:

Our sales are generally made by purchase orders. Because industry practice allows customers to reschedule
or cancel orders on relatively short notice, backlog is not a good indicator of our future sales. Cancellations of customer orders or changes in product specifications could result in the loss of anticipated sales without allowing us sufficient time
to reduce our inventory and operating expenses.

Since a significant portion of our revenue is from the digital consumer electronics
market, our business may be subject to seasonality, with increased revenues in the third and fourth calendar quarters of each year, when customers place orders to meet year-end holiday demand. However, broad fluctuations in our overall business in
the past several years makes it difficult for us to assess the impact of seasonal factors on our business.

We are subject to the risks of
conducting business internationally, including economic conditions in Asia, particularly Taiwan and China, changes in trade policy and regulatory requirements, duties, tariffs and other trade barriers and restrictions, the burdens of complying with
foreign laws and, possibly, political instability. All of our foundries and assembly and test subcontractors are located in Asia. Although our international sales are largely denominated in U.S. dollars, we do have sales transactions in New Taiwan
dollars, in Hong Kong dollars and in China Renminbi. In addition, we have foreign operations where expenses are generally denominated in the local currency. Such transactions expose us to the risk of exchange rate fluctuations. We monitor our
exposure to foreign currency fluctuations, but have not adopted any hedging strategies to date. There can be no assurance that exchange rate fluctuations will not harm our business and operating results in the future.

Restatement of Previously Issued Financial Statements

The information below has been adjusted to reflect the restatement of our financial results which is more fully described in the Explanatory Note immediately preceding Part 1, Item 1 and in Note 2 Restatement of
Condensed Consolidated Financial Statements to Condensed Consolidated Financial Statements of this Form 10-Q.

In this Form 10-Q, we
are restating our condensed consolidated balance sheet as of September 30, 2005, the related consolidated statements of operations for the three and nine months ended June 30, 2005, and the related consolidated statement of cash flows for
the nine months ended June 30, 2005 as a result of an independent stock option investigation commenced by the Special Committee of our Board of Directors. This restatement is also described in Note 2 Restatement of Condensed Consolidated
Financial Statements to our Condensed Consolidated Financial Statements. In our Form 10-K for the year ended September 30, 2006 to be filed with the Securities and Exchange Commission (the 2006 Form 10-K), we are restating our
consolidated balance sheet as of September 30, 2005, and the related consolidated statements of operations, shareholders equity, and cash flows for each of the fiscal years ended September 30, 2005 and September 30, 2004. In
addition, we are restating our unaudited quarterly financial information for all interim periods of fiscal year 2005 and the interim periods ended December 31, 2005 and March 31, 2006.

Financial information included in our reports on Form 10-K, Form 10-Q and Form 8-K filed by us prior to May 9, 2006, and the related opinions of our
independent registered public accounting firm and all earnings press releases and similar communications issued by us prior to May 9, 2006 should not be relied upon and are superseded in their entirety by this report and other reports on Form
10-Q and Form 8-K filed by us with the SEC on and after May 9, 2006.

The Special Committee Investigation

On July 18, 2006 and July 26, 2006, two purported shareholder derivative actions were filed against certain of our current and former directors
and officers alleging that our historical stock option granting practices from 1995 through 2002 violated federal and state law. In response to these lawsuits, management conducted a preliminary review of our historical stock option granting
practices.

On August 8, 2006, based on this review, our Board of Directors established a special committee (the Special
Committee), composed of two independent directors, to review our historical stock option practices and related accounting. We advised our independent registered public accounting firm, Ernst & Young LLP (E&Y), of the
formation of the Special Committee and the review to be conducted by such committee. Shortly thereafter, the Special Committee retained Latham

##### Table of Contents

and Watkins LLP as independent legal counsel and LECG as forensic accounting experts to conduct a full investigation of our past stock option granting
practices. The Special Committee was charged with reviewing our practices related to all stock option grants made by us during the review period, and examining the conduct of our current and former directors, officers, and employees involved in the
option grant process.

On August 9, 2006, we publicly announced the Special Committees investigation, and also filed a Form
12b-25 with the SEC stating that our June 30, 2006 Form 10-Q could not be filed until the investigation had been completed. On October 24, 2006, we filed a Form 8-K stating that our Board of Directors, with the concurrence of the Special
Committee, had determined that, pursuant to the requirements of APB 25, the actual measurement dates for financial accounting purposes of certain stock options granted primarily during fiscal years 1997-2005 differed from the recorded grant dates of
such awards, and that revised measurement dates for financial accounting purposes would apply to the affected awards, which would result in additional and material non-cash stock-based compensation expense. We further disclosed that, on
October 19, 2006, our Board of Directors, with the concurrence of the Special Committee, determined that we should restate our financial statements for various periods since our initial public offering in February 1995. Accordingly, we stated
that our financial statements and the related reports of our independent registered public accounting firm, E&Y, and all related earnings press releases and communications relating to periods after our initial public offering (IPO)
in February 1995, should not be relied upon.

The Special Committees Review Process

The Special Committee reviewed the facts and circumstances surrounding all stock option grants made during the period from January 1, 1997 through
July 2006 (the Review Period) as well as grants dated October 13, 1995 and November 8, 1996, which were identified in the derivative complaints, for a total of 104 grant dates. The Special Committee held sixteen meetings
and interviewed 20 individuals, including current and former employees of ISSI, our officers and directors, and outside counsel. The Special Committee reviewed over 390,000 electronic documents and 25 boxes of hard copy documents relating to stock
option grants. Collectively, the Special Committee and its advisors expended over 5,600 hours in the course of this investigation. The Special Committees investigation was conducted with the full support of current management and the Board. In
addition, the Company evaluated all grants in 1995 and 1996 since the date of the Companys initial public offering and concluded that any possible additional errors arising from grants made during this time would not be material to the
financial statements included in this Form 10-Q.

The Special Committee also reviewed the facts and circumstances surrounding the
potential backdating of cash and cash-less exercises of options. We considered whether the cash-less exercises or cash exercises had any accounting consequences such as potential compensation charges and additional income tax deductions. For
cash-less exercises, the exercise process utilized a third party broker so there was little chance for exercise date manipulation. For cash exercises, the Special Committee determined that the existing evidence and information available are
inconclusive. Had there been backdating of cash exercises, the potential maximum exposure of the compensation charge representing tax benefits forgone by the Company using fixed plan accounting, together with any underreported taxes would not be
material for any fiscal period.

Findings of the Special Committees Review

From the beginning of the Review Period through December 2005, we did not consistently follow our option grant procedures. Of the 104 grants under review,
the Special Committee was unable to find sufficient contemporaneous documentation to support the original measurement date for 73 grant dates. The Special Committee did find documentation to support the original measurement date for the remaining 31
grant dates, and because the accounting treatment for these grants is correct, they are not included in the accounting adjustment.

The 73
grant dates for which there was insufficient evidence to support the original grant date were further placed into one of three sub-categories:



| |  |  | Backdated. There are eight grant dates for which there is conclusive evidence that the original measurement date was selected retroactively. On these eight
grant dates, we granted options for approximately 3.0 million shares. The associated compensation charge through fiscal year 2005 is approximately $12.7 million.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Appears Misdated. There are 55 grant dates which resemble Backdated grants in that they were made on dates when the stock price was comparatively low, the
grants were added to our Equity Edge database (i.e., the software system we used to record stock option data) a significant amount of time after the purported date of grant, and meta-data from documents such as minutes or resolutions indicates that
these documents were created after the purported grant date. These grant dates differ from Backdated grants in that there is no email or testimonial evidence to directly support the inference that the grant dates were selected retroactively. On
these 55 grant dates, we granted options for approximately 10.9 million shares. The associated compensation charge is approximately $16.5 million through fiscal year 2005.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Appears Misdated/No Accounting Impact. There are ten grant dates that follow the same pattern as the Appears Misdated grants, but because the stock price on
the revised measurement date is lower than the stock price on the original measurement date, we will not recognize compensation expense on these misdated grants. On these ten grant dates, we granted options for approximately 2.3 million shares.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

After consideration of the accounting literature and recent guidance from the SEC staff, we have organized the grants
during the relevant period into categories based on grant type and the process by which the grant was finalized. We analyzed the evidence from the Special Committees investigation related to each category including, but not limited to,
physical documents, electronic documents, underlying electronic data about documents, and witness interviews. Based on the relevant facts and circumstances, we applied the then appropriate accounting standards to determine, for every grant within
each category, the proper measurement date. If the measurement date was not the originally assigned grant date, accounting adjustments were made as required, resulting in stock-based compensation expense and related tax effects.

The following summarizes our findings by type of grant:

Board of Director Grants. Outside directors receive option grants automatically pursuant to the Director Plan, which provides that the first grant occurs on the date a person becomes a director. Grants recur
automatically on the date each director is re-elected by shareholders. Grants were made to outside directors on 15 dates in the Review Period. We discovered one discrepancy and recorded $2,350 in stock compensation charges.

Officer Grants. Awards of option grants to executive officers (as defined in Section 16 of the Securities Exchange Act of 1934) were made
either by the Board of Directors as a whole, or by the Compensation Committee of the Board, which was comprised of non-management directors. Grants to executive officers were memorialized and approved in minutes of Board meetings or in documents
signed by our Compensation Committee. The Compensation Committee determined a specific number of stock options and salary compensation to officers, but delegated in a de facto manner its authority to select the grant dates and exercise prices to our
former Chief Financial Officer, Gary L. Fischer, including at times when he was not a member of the Board of Directors. The Compensation Committee thereafter authorized the grants, without knowledge of how Mr. Fischer selected the grant dates
or prices. We have concluded that the authorization by the Compensation Committee was perfunctory and therefore could not be relied upon to determine the grant date. Grants to executive officers were made on 21 dates and include approximately
2.4 million shares. Four grants were categorized as Backdated, seven grants were categorized as Appears Misdated, and ten of these grant dates were categorized as Correct. The ten grants categorized as correct had original measurement dates
that were deemed appropriate based upon various contemporaneous documentation that indicated that the exercise price and the number of options granted to individual recipients were known with finality at the original measurement dates. The
associated compensation charge is approximately $3.4 million through fiscal year 2005.

Non-executive Employee Grants (New Hire,
Follow-on, and Bonus). Option grants awarded to employees who were not then executive officers (as defined in Section 16 of the Securities Exchange Act of 1934) were memorialized and approved in documents signed by our Stock Option
Committee, pursuant to authority delegated by the Board of Directors. The Stock Option Committee was made up of our Chief Executive Officer and a non-management director. The Special Committee concluded that the Stock Option Committee delegated in a
de facto manner its authority to select the grant dates and exercise prices to our former Chief Financial Officer, Gary L. Fischer, including at times when he was not a member of the Board of Directors. The quantity of shares granted were typically
based on salary range guidelines set by us and approved by the Stock Option Committee. The Stock Option Committee thereafter authorized the grants, without knowledge of how Mr. Fischer had selected the grant dates or prices. We have concluded
that the authorization by the Stock Option Committee was perfunctory and therefore could not be relied upon to determine the grant date. Grants to non-executive employees were



30

##### Table of Contents

made on 76 dates during the Review Period, and totaled approximately 13.6 million shares. Grants on six dates were categorized as Backdated and 52 grant
dates were categorized as Appears Misdated, representing approximately 10.2 million shares. The associated compensation charge is approximately $21.5 million through fiscal year 2005. In addition, ten grants were categorized as Appears
Misdated/No Accounting Impact and eight grants were categorized as Correct, representing approximately 3.4 million shares. The eight grants categorized as correct had original measurement dates that were deemed appropriate based upon various
contemporaneous documentation that indicated that the exercise price and the number of options granted to individual recipients were known with finality at the original measurement dates.

Salary Reduction Grants. We granted options to officers and employees in connection with five salary reduction programs. Three of these grant
dates were categorized as Backdated (representing 535,716 shares) and two grant dates were categorized as Appears Misdated (representing 254,965 shares). These totals exclude any grants to officers, as they were previously included in the Officer
Grant totals. The associated compensation charge is approximately $2.2 million through fiscal year 2005.

Stock Option Re-pricing
Grants. We granted options to officers and employees four times in connection with stock option re-pricing programs. On October 13, 1995, we granted 699,000 options (excluding options to officers); this grant was categorized as Correct. On
December 6, 1996 we granted 75,000 options to officers and on December 27, 1996 we granted 847,000 options to employees; both of these grants, which were outside of the Review Period, have been determined to be Correct by us. On
December 2, 1998, we granted 1,622,418 options (excluding options to officers); this grant was categorized as Appears Misdated (the appropriate measurement date was determined to be December 11, 1998). These re-pricing grants predated the
adoption of FIN 44 and we applied EITF Issue No. 87-33, Stock Compensation Issues Related to Market Decline (EITF Issue No. 87-33). The associated fixed compensation charge is approximately $2.1 million through fiscal year 2005. During the
investigation we identified that 232,050 options granted, all to non-officers, in the December 1998 re-pricing represented options re-priced a third time and are being considered variable awards under EITF 87-33. We have recorded the related charges
of approximately $2.3 million over the Review Period as part of this restatement.

Consultant Grants. During the Review Period, we
made one grant to a consultant that was not properly recorded. A total of 25,000 shares were granted on March 23, 1998 which was the date of the consulting contract. Compensation expense of $74,000 was recorded as per FASBs Emerging
Issues Task Force Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services (EITF 96-18).

Modification of Grants.There were 20 option grants which were modified between the periods of 1997 to 2003 to have the exercise period extended.
Under FIN 44 Compensation, we have recorded additional compensation expense for the modification of these option grants. The additional compensation charge for the affected options, calculated as the difference between the intrinsic value on the
award date and the intrinsic value on the modification date, amounted to $440,000.

Consideration for Revised Measurement Dates

We have identified two types of fact patterns regarding the available evidence regarding grants made during the Review Period. In Fact Pattern One, we
found documentation to identify a specific date on which the grantees, the number of shares, and the prices of the options were known and support the original measurement date. Grants falling within this first fact pattern are primarily grants to
directors and officers. Options granted from February 2006 onward also fall within this category, because at that time, we instituted new procedures for granting stock options. These procedures require contemporaneous documentation of the date of
grant. The 31 grants in this category did not require revised measurement dates.

In Fact Pattern Two, for most grants in the Review
Period, it is not possible to ascertain with certainty from the available evidence when the list of grantees was final. For these 73 grants, there was insufficient contemporaneous evidence related to the Original Measurement Date. For four grants in
this category, contemporaneous evidence exists to support a revised measurement date

Based on the evidence, we have concluded that we
should consider all available evidence to determine the earliest date that the terms of options to individual recipients were known with finality for all grants which fall into the categories Backdated, Appears Misdated and Appears Misdated/No
Accounting Impact (other than for FAS 123 Pro Forma purposes), for purposes of selecting the Revised Measurement Dates. For the vast majority of grants, we have concluded, based on all



31



---

##### Table of Contents

available evidence, that the Equity Edge Record Added Date is the earliest date when the terms of options to individual recipients were known with finality
and therefore that is the Revised Measurement Date. Alternative measurement dates were used when other documentary evidence exists to support such dates such as dated Unanimous Written Consents, or in the case of a grant to a new director, the date
of commencement of service. Alternative methods for determining revised measurement dates were used on four grants as the documentary evidence for the grants either identified with certainty the date the terms of the option to individual recipients
were known with finality or supported, when uncertainty remains, a date earlier than the Equity Edge entry date.

The Equity Edge Record
Added date represents a contemporaneous, fixed, identifiable date in the option grant process, which evidences that we had incurred a legal obligation to the employee-recipient and that the criteria listed in Paragraph 10(b) of APB 25 were met.
There is significant evidence that the terms of the grants were final by the time they were entered into Equity Edge. Furthermore, based on the lack of verifiable contemporaneous documentation, the Equity Edge Record Added date represents the
earliest determinable date as of which the criteria listed in Paragraph 10(b) of APB 25 were met, as both the exercise price and the number of options granted to each individual were known on that date. Based on the apparent practice utilized by
Mr. Fischer to grant stock awards using hindsight, we believe that the APB 25 criteria were not met at the earlier stated grant date, and it is likely that the exercise price was not established until a point close to the Equity Edge Entry
Date.

Findings of the Special Committee Concerning Conduct of Individuals

On December 12, 2006, the Special Committee presented the findings of its investigation to, and recommended certain remedial measures for adoption
by, the Board of Directors. The Board of Directors accepted all of the findings of the Special Committee and all of the proposed remedial measures. As a result of the Special Committees investigation, as well as our internal review of our
historical financial statements, we have determined the following:



| |  |  | Prior to the improvements to our internal control systems beginning in March 2006 made by our new CFO, we did not maintain adequate controls and procedures for
granting, accounting for, and reporting stock option grants. Our stock option plans require that grants to officers be approved by the Compensation Committee and grants to other employees be approved by our Stock Option Committee. As a matter of
practice, however, grant dates and the corresponding exercise prices were selected without a formal delegation of authority by our former Chief Financial Officer, Gary L. Fischer, including at times when he was not a director of ISSI. In addition,
Mr. Fischer was never a member of either the Stock Option or Compensation Committees. Documents authorizing the grants on the dates selected by Mr. Fischer were subsequently prepared at Mr. Fischers direction and presented to
the Compensation and Stock Option Committee members for signature.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Based on the totality of the information available to
it, the Special Committee found that certain individuals were responsible for the lack of effective controls and the inappropriate grant practices. Specifically:



| |  |  | The Special Committee found that Mr. Fischer appears to have selected a number of grant dates with the benefit of hindsight in order to obtain favorable
exercise prices. Mr. Fischer benefited personally from certain of these grants. Mr. Fischer paid cash to exercise certain stock options, but paid $23,632 less than he should have paid due to improper measurement dates associated with stock
options. Mr. Fischer also realized gains from the cashless exercise of options through an independent broker, and same-day sale of our Common Stock, of which $360,344 represented gains derived from improper measurement dates associated with
stock options. In addition, following the conclusion of the Special Committees investigation in December 2006, we terminated the consulting agreement we had entered into with Mr. Fischer in December 2005. Mr. Fischer voluntarily
agreed in December 2006 to amend and increase the exercise prices of certain option grants with improper measurement dates that otherwise would have been subject to Section 409A of the Internal Revenue Code.

| |  |  | Chairman and Chief Executive Officer Jimmy Lee was involved in the process of granting options to employees who were not Section 16 Officers through his
membership on the Stock Option Committee. The Stock Option Committee delegated in a de facto manner the task of selecting grant dates to Mr. Fischer without knowledge of how Mr. Fischer selected such dates. As a member of the Stock Option
Committee, Mr. Lee signed documents that were drafted at Mr. Fischers direction authorizing those grants. The Special Committee concluded, however, that Mr. Lee relied on

| | Mr. Fischer and did not understand the accounting requirements or legal implications of our stock option granting practices. Mr. Lee was
forthcoming and cooperated fully with the investigation. As recommended by the Special Committee, as described below, we have admonished Mr. Lee for failing to establish a proper control environment and informally delegating authority to
Mr. Fischer, Mr. Lee has voluntarily agreed to give up any economic benefit he received from the improper measurement dates, and the Compensation Committee or the Board is now responsible for granting non-executive stock options.
Mr. Lee benefited personally from certain grants with improper measurement dates, specifically, he paid cash to exercise stock options but paid $257,329 less than he should have paid if the exercise prices had been established based on the
stock price on the Revised Measurement Date. Mr. Lee has voluntarily agreed to repay this amount to us. In addition, Mr. Lee held vested in-the-money stock options, of which $7,200 represented holding gains associated with improper
measurement dates based on the closing price of our Common Stock on March 21, 2007. Mr. Lee voluntarily agreed to amend and increase the exercise prices of all of his vested and unvested stock options, including options that otherwise
would have been subject to Section 409A of the Internal Revenue Code, which will eliminate any potential future gains he would have received as a result of the improper measurement dates. .

| |  |  | Two of our current directors, Lip-Bu Tan and Hide Tanigami, were involved in the stock option granting process. Mr. Tan and Mr. Tanigami were members of
the Compensation Committee. In addition, Mr. Tan along with Mr. Lee served on the Stock Option Committee. The Compensation and Stock Option Committee members delegated in a de facto manner the task of selecting grant dates to
Mr. Fischer, without knowledge of how Mr. Fischer selected grant dates, and signed documents that were drafted at Mr. Fischers direction authorizing those grants. The Special Committee concluded, however, that Mr. Tan and
Mr. Tanigami relied upon Mr. Fischer and did not understand the accounting requirements or legal implications of our stock option granting practices. Both Mr. Tan and Mr. Tanigami were forthcoming and cooperated fully with the
investigation. As recommended by the Special Committee, Mr. Tan and Mr. Tanigami no longer serve on the committees responsible for granting stock options. In addition, Mr. Tanigami holds one option grant that is presently
out-of-the-money that he voluntarily agreed to reprice to the adjusted exercise price to eliminate a potential gain of $2,350 due to the improper measurement date.

without knowledge of how Mr. Fischer selected grant dates. As recommended by the Special Committee, the current employees were admonished and they will receive additional training. In addition, they voluntarily agreed to reprice certain
out-of-the-money options to the new higher measurement price which are not subject to Section 409A of the Internal Revenue Code to eliminate any potential gain due to improper measurement dates.

Financial Impact of the Adjustments to the Measurement Dates

Based on the results of the equity award review, the Audit Committee concluded that, pursuant to APB 25, and related interpretations, the accounting measurement dates for most of the stock option grants awarded between 1995 through 2005,
covering options to purchase 19.3 million shares of our common stock, differed from the measurement dates previously used for such awards. As a result, revised measurement dates were applied to the affected option grants and we have recorded a
total of $29.2 million in additional non-cash stock-based compensation expense for the years 1997 through 2005. Of the $29.2 million, $25.6 million utilized the equity edge entry dates. This amount is net of forfeitures related to employee
terminations. The additional stock-based compensation expense is being amortized over the service period relating to each option which is typically four years.

Stock Option grants that were intended to qualify as Incentive Stock Options (ISOs) under the Internal Revenue Code but were granted in-the-money as described above would not receive the
favorable tax treatment under the ISOs. As such, the employer and employee portions of certain payroll tax amounts were not appropriately withheld when the options were exercised. Had we recorded these expenses as they occurred, then we would have
recognized an additional tax expense of $368,000 over the period. We intend to enter into settlement discussions with the Internal Revenue Service in June 2007 regarding this matter for those tax years which are still open with the IRS: 2004, 2005,
and 2006. Based on our assessment, the payroll tax and withholding liability is approximately $13,000 for those periods. We intend to pay the amounts including the amounts on behalf of the employees. We are recording charges for each year in which
the payroll tax should have been assessed, and then reversing that charge in the fiscal year when the statute of limitations expires. These charges have been recorded in the financial statements as compensation cost.

In our restatements for fiscal years 1997 to 2003 and 2005, no adjustments were made to the originally
reported income tax provision or benefit resulting from the additional stock-based compensation expenses. No tax benefits were recorded for additional stock-based compensation for these years since such amounts were offset by valuation allowances
which would not be realized given the existence of operating losses and lack of earnings history. In our restatement for fiscal year 2004, a $52,000 reduction to the amount of originally reported tax provision was recorded to reflect the tax
benefits that the additional stock-based compensation had to the federal alternative minimum tax expense.

The impact of the restatement is
summarized as follows:

Judgment

In light of the significant judgment used in establishing revised measurement date, alternate approaches to those used by us could have resulted in different compensation expense charges then those recorded by us in the restatement. We
prepared a sensitivity analysis to determine the possible maximum compensation expense charge that could occur if an alternative methodology to determine the revised measurement date were chosen. We only provided a maximum range to this sensitivity
analysis as in most situations the original prices were near or at the lowest in the period, and if a lower price were to be determined to be the revised measurement date, then there would be no resulting compensation charges. Also, we considered
other possible alternative grant dates for determining a sensitivity analysis based on all available data but were unable to find any such data or evidence that would provide a reasonable alternative. The sensitivity analysis is formulated to
provide the reader of the financial statements with the potential impact of a change in measurement dates on the recognized compensation expense.

We applied an expense sensitivity methodology to examine the largest possible variations in stock-based compensation expense with a range of possible approval dates for each grant event. We developed this range using the original grant date
as the earliest date and the revised measurement date as the end date. Our approach resulted in a broad range of dates which in some situations would produce an alternate measurement date before the terms of a grant would be met under APB25.
However, based on all available evidence, such as unanimous written consents, email dates, and Board of Director or committee meeting dates, we were unable to identify dates that would provide a more reasonable range of dates for this sensitivity
analysis. While we believe the evidence and methodology used to determine the revised measurement dates to be the best available, we also believe that illustrating the difference in stock-based compensation expense using the highest price provides
the reader of financial statements possible insight into the potential fluctuations in stock-based compensation expense if alternate dates had been chosen by the Company.

After developing the range for the grant dates, we selected the high closing price of our stock within the range for each grant event and calculated the difference in stock-based compensation expense for the
high stock price within the range. We compared this aggregated amount to the stock-based compensation that we selected through our evaluation. Had we used the highest closing price of our stock within the range, our total restated stock-based
compensation adjustment relating to the revision in measurement dates would have been increased by approximately $13.7 million. Since we do not have evidence that the grant dates and exercise prices were selected on the date when our stock price was
at it highest during each period, we concluded that the use of the highest closing price when measuring compensation expense would not have been consistent with the requirements of ABP 25 which looks to the first date on
which the amounts, individuals and price were known.

The results of the sensitivity analysis are summarized by grant type as follows:

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make difficult and subjective estimates, judgments and assumptions. These
estimates, judgments and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during
the reporting period. The estimates and judgments that we use in applying our accounting policies have a significant impact on the results we report in our financial statements. We base our estimates and judgments on our historical experience
combined with knowledge of current conditions and our beliefs of what could occur in the future, considering the information available at the time. Actual results could differ from those estimates and such differences may be material to our
financial statements. We reevaluate our estimates and judgments on an ongoing basis.

Our critical accounting policies which are impacted
by our estimates are: (i) the valuation of our inventory, which impacts cost of goods sold and gross profit; (ii) the valuation of our allowance for sales returns and allowances, which impacts net sales; (iii) the valuation of our
allowance for doubtful accounts, which impacts general and administrative expense; (iv) accounting for acquisitions and goodwill, which impacts other expense when we record impairments; (v) the valuation of our non-marketable equity
securities, which impacts other expense when we record impairments and (vi) accounting for stock-based compensation which impacts costs of goods sold, research and development expense and selling, general and administrative expense. Each of
these policies is described in more detail below. We also have other key accounting policies that may not require us to make estimates and judgments that are as subjective or difficult. For instance, our policies with regard to revenue recognition,
including the deferral of revenues on sales to distributors with sales price rebates and product return privileges. These policies are described in the notes to our financial statements contained in our Annual Report on Form 10-K for the fiscal year
ended September 30, 2005.

Valuation of inventory. Our inventories are stated at the lower of cost or market value.
Determining market value requires us to project unit prices and volumes for future periods in which we expect to sell inventory on hand as of the balance sheet date. As a result of these estimates, we may record a charge to cost of goods sold, which
decreases our gross profit, in advance of when the inventory is actually sold to reflect market values, net of sales commission costs, that are below our manufacturing costs. Conversely, if we sell inventory that has previously been written down to
the lower of cost or market at more favorable prices than we had forecasted at the time of the write-down, our gross profit may be higher. In addition to lower of cost or market write-downs, we also analyze inventory to determine whether any of it
is excess, obsolete or defective. We write down to zero dollars (which is a charge to cost of goods sold) the carrying value of inventory on hand in excess of six months historical sales volumes to cover estimated excess and obsolete
exposures, unless adjustments are made based on our judgments for newer products, end of life products, planned inventory increases or strategic customer supply. In making such judgments to write down inventory, we take into account the product life
cycles which can range from six to 30 months, the stage in the life cycle of the product, and the impact of competitors announcements and product introductions on our products.

Valuation of allowance for sales returns and allowances. Net sales consist principally of total product sales less estimated sales returns.
To estimate sales returns and allowances, we analyze potential customer specific product application issues, potential quality and reliability issues and historical returns. We evaluate quarterly the adequacy of the reserve for sales returns and
allowances. This reserve is reflected as a reduction to accounts receivable in our consolidated balance sheets. Increases to the reserve are recorded as a reduction to net sales. Because the reserve for sales returns and allowances is based on our
judgments and estimates, particularly as to product application, quality and reliability issues, our reserves may not be adequate to cover actual sales returns and other allowances. If our reserves are not adequate, our net sales could be adversely
affected.

Valuation of allowance for doubtful accounts. We maintain an allowance for doubtful accounts for losses that we
estimate will arise from our customers inability to make required payments for goods and services purchased from us. We make our estimates of the uncollectibility of our accounts receivable by analyzing historical bad debts, specific customer
creditworthiness and current economic trends. Once an account is deemed unlikely to be fully collected, we write down the carrying value of the receivable to the estimated recoverable value, which results in a charge to general and administrative
expense, which decreases our profitability.

Accounting for acquisitions and goodwill. We account for acquisitions using the purchase
accounting method in accordance with SFAS 142, Goodwill and Other Intangible Assets. Under this method, the total consideration paid, excluding, if any, the contingent consideration that has not been earned, is allocated over the fair
value of the net assets acquired, including in-process research and development, with any excess allocated to goodwill. Goodwill is defined as the excess of the purchase price over the fair value allocated to the net assets. Our judgments as to fair
value of the assets will, therefore, affect the amount of goodwill that we record. We engage a qualified third party valuation firm that specializes in the valuation of tangible and intangible assets to advise us in the valuation analysis. The
valuation firm will deliver a written analysis of the values assessed. For tangible assets acquired in any acquisition, such as plant and equipment, the useful lives are estimated by considering comparable lives of similar assets, past history, the
intended use of the assets and their condition. In estimating the useful life of the acquired intangible assets with definite lives, we and our valuation firm consider the industry environment and unique factors relating to each product relative to
our business strategy and the likelihood of technological obsolescence. Acquired intangible assets primarily include core and current technology, customer relationships and customer contracts. We are currently amortizing our acquired intangible
assets with definite lives over periods generally ranging from six months to six years.

We perform goodwill impairment tests on an annual
basis and between annual tests in certain circumstances. In response to changes in industry and market conditions, we could be required to strategically realign our resources and consider restructuring, disposing of, or otherwise exiting businesses,
which could result in an impairment of goodwill. In fiscal 2005, we recorded charges for impairment of goodwill in the amount of $4.4 million.

Valuation of non-marketable securities. Our ability to recover our strategic investments in equity securities that are non-marketable and to earn a return on these investments is largely dependent on financial market conditions
and the occurrence of liquidity events, such as initial public offerings, mergers or acquisitions, and private equity transactions. The timing of when any of these events may occur is uncertain and very difficult to predict. In addition, under our
accounting policy, we are required to periodically review all of our investments for impairment. In the case of non-marketable equity securities, this requires significant judgment on our part, including an assessment of the investees
financial condition, the existence of subsequent rounds of financing and the impact of any relevant equity preferences, as well as the investees historical results of operations and projected results and cash flows. If the actual outcomes for
the investees are significantly different from their forecasts, the carrying value of our non-marketable equity securities may be above fair value, and we may incur additional charges in future periods, which will decrease our profitability.
In fiscal 2005, we recorded approximately $0.3 million impairment losses related to two of our non-marketable equity securities. At June 30, 2006, our strategic investments in non-marketable securities totaled $3.5 million.

Accounting for stock-based compensation.Effective October 1, 2005, we adopted the fair value recognition provisions of SFAS No. 123
(revised 2004), Share-Based Payment (SFAS 123R), using the modified prospective transition method and therefore have not restated results for prior periods. Under this transition method, stock-based compensation expense in fiscal
2006 included stock-based compensation expense for all share-based payment awards granted prior to, but not yet vested as of October 1, 2005, based on the grant-date fair value estimated in accordance with the original provision of SFAS
No. 123, Accounting for Stock-Based Compensation (SFAS 123). Stock-based compensation expense for all share-based payment awards granted after October 1, 2005 is based on the grant-date fair value estimated in accordance
with the provisions of SFAS 123R. We recognize these compensation costs on a straight-line basis over the requisite service period of the option, which is generally the option vesting term of four years. Prior to the adoption of SFAS 123R,
we recognized stock-based compensation expense in accordance with Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees (APB 25). Under APB 25, when the exercise price of our employee stock
options was equal to the market price of the underlying stock on the date of the grant, no compensation expense was recognized. In March 2005, the Securities and Exchange Commission (the SEC) issued Staff Accounting Bulletin No. 107
(SAB 107) regarding the SECs interpretation of SFAS 123R and the valuation of share-based payments for public companies. We have applied the provisions of SAB 107 in its adoption of SFAS 123R.

Impact of Recently Issued Accounting Standards

In May 2005, the Financial Accounting Standards Board (FASB) FASB issued SFAS No. 154, Accounting Changes and Error Corrections
(SFAS 154) which replaces APB Opinion No. 20 Accounting Changes and SFAS No. 3, Reporting Accounting Changes in Interim Financial StatementsAn Amendment of APB Opinion No. 28. SFAS 154 provides
guidance on the accounting for and reporting of accounting changes and error corrections. It establishes retrospective application, or the latest practicable date, as the required method for reporting a change in accounting principle and the
reporting of a correction of an error. SFAS 154 is effective for accounting changes and correction of errors made in fiscal years beginning after December 15, 2005 and is required to be adopted by us in the first quarter of fiscal 2007. We
do not expect that the adoption of SFAS 154 will have a material impact on our consolidated results of operations and financial position.

In June 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement No. 109. The interpretation contains a two step approach to recognizing
and measuring uncertain tax positions accounted for in accordance with SFAS No. 109. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the
position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate
settlement. The provisions are effective us beginning in the first quarter of fiscal 2008. We are currently evaluating the impact this statement will have on our consolidated financial statements.

In September 2006, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin No. 108, Considering the Effects of
Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (SAB 108). SAB 108 gives guidance on how errors, built up over time in the balance sheet, should be considered from a materiality perspective and
corrected. SAB 108 provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. SAB 108 is effective for fiscal years ending after
November 15, 2006, and early application is encouraged. We are currently evaluating the impact that the provisions will have on our consolidated balance sheet and statement of operations.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS No. 157) which establishes a framework for
measuring fair value and enhance disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. The measurement and disclosure requirements are effective for us beginning in the first
quarter of fiscal 2009. We are currently evaluating whether SFAS No. 157 will result in a change to our fair value measurements.

In
September 2006, the FASB issued SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement PlansAn Amendment of FASB Statements No. 87, 88, 106, and 132R (SFAS No. 158).
SFAS No. 158 requires that the funded status of defined benefit postretirement plans be recognized on our balance sheet, and changes in the funded status be reflected in comprehensive income, effective fiscal years ending after
December 15, 2006. SFAS No. 158 also requires the measurement date of the plans funded status to be the same as our fiscal year-end. This requirement is not required until fiscal 2008. We are currently evaluating the impact that the
provisions will have on our consolidated balance sheet and statement of operations.

In February 2007, the FASB issued SFAS No. 159,
The Fair Value Option for Financial Assets and Financial Liabilities (SFAS No. 159) which permits companies to choose to measure certain financial instruments and certain other items at fair value. The standard requires that
unrealized gains and losses on items for which the fair value option has been elected be reported in earnings. SFAS 159 is effective for us beginning in the first quarter of fiscal 2009, although earlier adoption is permitted. We are currently
evaluating the impact SFAS No. 159 will have on our consolidated financial statements.

Three Months Ended June 30, 2006 Compared to Three Months Ended June 30, 2005 (restated)

Net sales. Net sales consist principally of total product sales less estimated sales returns. Net sales decreased by 1% to
$53.2 million in the three months ended June 30, 2006 from $53.7 million in the three months ended June 30, 2005. The decrease in net sales of $0.5 million can principally be attributed to a shift in product mix from DRAM to SRAM products
in the three months ended June 30, 2006 compared to the three months ended June 30, 2005. The overall increase in SRAM revenue is attributable to an increase in unit sales which more than offset a decline in average selling prices. The
increase in SRAM revenue more than compensated for the decrease in DRAM revenue which was a result of decreasing average selling prices in conjunction with a decrease in unit sales during the three months ended June 30, 2006 compared to the
three months ended June 30, 2005. We anticipate that the average selling prices of our existing products will generally decline over time, although the rate of decline may fluctuate for certain products. There can be no assurance that any
future price declines will be offset by higher volumes or by higher prices on newer products.

Gross profit. Cost of sales includes
die cost from the wafers acquired from foundries, subcontracted package, assembly and test costs, costs associated with in-house product testing, quality assurance and import duties. Gross profit decreased by $3.0 million to $4.3 million in the
three months ended June 30, 2006 from $7.3 million in the three months ended June 30, 2005. Our gross margin decreased to 8.1% in the three months ended June 30, 2006 from 13.6% in the three months ended June 30, 2005. Our gross
profit for the three months ended June 30, 2006 included inventory write-downs of $4.9 million while our gross profit for the three months ended June 30, 2005 did not contain any inventory write-downs. The inventory write-downs were for
excess and obsolescence issues and lower of cost or market accounting on certain of our products. Excluding the inventory write-downs in the three months ended June 30, 2006, the increase in gross profit in the three months ended June 30,
2006 compared to the June 2005 period can be attributed to increased unit shipments of SRAM products which more than offset declines in average selling prices for such products. The gross profit for our DRAM products was relatively unchanged in the
three months ended June 30, 2006 compared to the three months ended June 30, 2005. The decrease in our gross margin in the June 2006 quarter as compared to the June 2005 quarter can be primarily attributed to the inventory write-downs in
the June 2006 quarter. In addition, declines in the average selling prices of our SRAM products more than offset declines in the cost of our SRAM products in three months ended June 30, 2006 compared to three months ended June 30, 2005
resulting in a decline in our SRAM gross margin. However, declines in the cost of our DRAM products more than offset declines in the average selling prices of our DRAM products in three months ended June 30, 2006 compared to the three months
ended June 30, 2005. This contributed to an increase in our DRAM gross margin. We believe that the average selling prices of our products will decline over time and, unless we are able to reduce our cost per unit to the extent necessary to
offset such declines, the decline in average selling prices will result in a material decline in our gross margin. In addition, product costs could increase if our suppliers raise prices, which could result in a material decline in our gross margin.
In the past, foundries have raised wafer prices when demand for end products increases. Although we have product cost reduction programs in place that involve efforts to reduce internal costs and supplier costs, there can be no assurance that
product costs will be reduced or that such reductions will be sufficient to offset the expected declines in average selling prices. We do not believe that such cost reduction efforts are likely to have a material adverse impact on the quality of our
products or the level of service provided by us.

Research and development. Research and development expenses increased by 3% to
$5.5 million in the three months ended June 30, 2006 compared to $5.3 million in the three months ended June 30, 2005. As a percentage of net sales, research and development expenses increased to 10.1% in the three months ended
June 30, 2006 from 9.8% in the three months ended June 30, 2005. The three months ended June 30, 2006 includes stock-based compensation expense under SFAS 123R of approximately $0.4 million and the three months ended June 30,
2005 includes stock-based compensation of approximately $0.2 million. From the June 2005 period to the June 2006 period, research and development expenses also increased due to our consolidation of ICSI but such increase was offset by a decrease in
research and development expenses in the U.S. and for Bluetooth and Flash controller development projects which we exited in the March 2006 quarter. The three months ended June 30, 2006, included $0.5 million attributable to SRAM mask works
acquired in an asset purchase from Alliance Semiconductor (Alliance). Our research and development expenses could increase in absolute dollars in future periods due to increased costs associated with the development of new products.

Selling, general and administrative. Selling, general and administrative expenses increased by 5% to $6.5 million in the three months ended
June 30, 2006 from $6.2 million in the three months ended June 30, 2005. As a percentage of net sales, selling, general and administrative expenses increased to 11.9% in the three months ended June 30, 2006 from 11.6% in

the three months ended June 30, 2005. The three months ended June 30, 2006 includes stock-based compensation expense under SFAS 123R of
approximately $0.5 million and the three months ended June 30, 2005 includes stock-based compensation of approximately $0.2 million. From the June 2005 period to the June 2006 period, selling, general and administrative expenses also increased
due to our consolidation of ICSI but such increase was offset by a decrease in selling, general and administrative expenses for the Bluetooth and Flash controller markets. Complying with the internal control requirements under Section 404 of
the Sarbanes-Oxley Act of 2002 which apply to our operations at ICSI beginning in fiscal 2006, has had and will continue to result in increased internal efforts, significantly higher fees from our independent accounting firm and significantly higher
fees from third party contractors. As a result, our selling, general and administrative expenses may increase in absolute dollars in future quarters, although such expenses may fluctuate as a percentage of net sales.

Acquired in-process technology charge. The $1.5 million allocated to in-process technology charge (IPR&D) in the three months ending
June 30, 2005 related to our acquisition of ICSI in May 2005.

Interest and other income (expense), net. Interest and other
income (expense), net was $0.7 million in the three months ended June 30, 2006 compared to $0.9 million in the three months ended June 30, 2005. These amounts were comprised primarily of interest income. In addition, in the three months
ended June 30, 2005, we recorded a gain of approximately $0.2 million from the sale of fixed assets.

Gain on sale of
investments. The gain on the sale of investments was $0.3 million in the three months ended June 30, 2006 compared to $0.5 million in the three months ended June 30, 2005. In the three months ended June 30, 2006, we sold our
investment in E-CMOS for approximately $1.5 million which resulted in a pre-tax gain of $0.3 million. In the three months ended June 30, 2005, we sold our equity interest in NexFlash for approximately $2.2 million which resulted in a pre-tax
gain of $0.5 million.

Provision for income taxes.The provision for income taxes for the three month period ended June 30,
2006 of $51,000 consists primarily of foreign withholding taxes and taxes in foreign jurisdictions. The provision for income taxes for the three month period ended June 30, 2005 of $9,000 consists of foreign withholding taxes.

Minority interest in net loss of consolidated subsidiaries.The minority interest in net loss of consolidated subsidiaries was $38,000 in the
three months ended June 30, 2006 compared to $445,000 in the three months ended June 30, 2005. The minority interest in net loss of consolidated subsidiaries for the three months ended June 30, 2006 represents the minority
shareholders proportionate share of the net loss of ICSI for the quarter. The minority interest in net loss of consolidated subsidiaries for the three months ended June 30, 2005 includes the minority shareholders proportionate share
of the net loss of ICSI for the two months ended June 30, 2005. On May 1, 2005, ISSI assumed effective control of ICSI and in accordance with generally accepted accounting principles we began consolidating the financial results of ICSI
with our own results as of such date. In addition, the three months ended June 30, 2005 includes the minority shareholders proportionate share of the net loss of Signia. Effective March 2006, we account for Signia on the cost basis.

Equity in net loss of affiliated companies.Equity in net loss of affiliated companies was $0.2 million in the three months ended
June 30, 2006 compared to a $1.1 million loss in the three months ended June 30, 2005. In the three months ended June 30, 2006, we recorded a loss of approximately $0.2 million related to our equity interest in KSC. The $1.1 million
loss in the three months ended June 30, 2005 primarily reflects our equity interest in ICSIs financial results for Apri1 2005. Effective May 1, 2005, we began consolidating the financial results of ICSI with our results in accordance
with generally accepted accounting principles.

Nine Months Ended June 30, 2006 Compared to Nine Months Ended June 30, 2005 (restated)

Net Sales. Net sales increased by 31% to $157.6 million in the nine months ended June 30, 2006 from $120.0 million in
the nine months ended June 30, 2005. The increase in net sales of $37.6 million can principally be attributed to our acquisition of a controlling interest in and the resulting consolidation of ICSIs results of operations beginning in May
2005. An increase in unit shipments of our DRAM products in the nine months ended June 30, 2006 compared to the nine months ended June 30, 2005 more than offset a decline in average selling prices resulting in an overall increase in DRAM
revenue. In addition, an increase in unit shipments of our SRAM products in the nine months ended June 30, 2006 compared to the nine months ended June 30, 2005 more than offset a decrease in average selling prices resulting in an overall
increase in SRAM revenue.

Gross profit. Gross profit increased by $11.4 million to $17.4 million in the nine months ended
June 30, 2006 from $6.0 million in the nine months ended June 30, 2005. Our gross margin increased to 11.0% in the nine months ended June 30, 2006 from 5.0% in the nine months ended June 30, 2005. Our gross profit for the nine
months ended June 30, 2006 included inventory write-downs of $14.3 million while our gross profit for the nine months ended June 30, 2005 included inventory write-downs of $10.9 million. The inventory write-downs were for excess and
obsolescence issues and lower of cost or market accounting on certain of our products. The increase in gross profit in the nine months ended June 30, 2006 can be attributed to increased unit shipments of DRAM and SRAM products due to our
acquisition of ICSI which more than offset declines in average selling prices for such products. Also, we recognized $2.3 million of gross profit on inventory sold during the nine months ended June 30, 2006 that had been previously written-off.
The increase in the gross margin in the nine months ended June 30, 2006 compared to the nine months ended June 30, 2005 can be primarily attributed to declines in the cost of our DRAM products which more than offset declines in the average
selling prices of our DRAM products. This contributed to an increase in our DRAM gross margin. However, declines in the average selling prices of our SRAM products more than offset declines in the cost of our SRAM products in the nine months ended
June 30, 2006 compared to nine months ended June 30, 2005 resulting in a decline in our SRAM gross margin.

Research and
development. Research and development expenses increased by 7% to $16.6 million in the nine months ended June 30, 2006 from $15.5 million in the nine months ended June 30, 2005. As a percentage of net sales, research and development
expenses decreased to 10.4% in the nine months ended June 30, 2006 from 12.9% in the nine months ended June 30, 2005. The nine months ended June 30, 2006 includes stock-based compensation expense under SFAS 123R of approximately $1.6
million and the nine months ended June 30, 2005 includes stock-based compensation of approximately $0.8 million. From the nine months ended June 30, 2005 to the nine months ended June 30, 2006, research and development expenses also
increased due to our consolidation of ICSI but such increase was offset by a decrease in research and development expenses in the U.S. and for Bluetooth and Flash controller development projects which we exited in the March 2006 quarter. The nine
months ended June 30, 2006 included $0.5 million attributable to SRAM mask works acquired in an asset purchase from Alliance. Our research and development expenses could increase in absolute dollars in future periods due to increased costs
associated with the development of new products.

Selling, general and administrative. Selling, general and administrative expenses
increased by 25% to $20.4 million in the nine months ended June 30, 2006 from $16.3 million in the nine months ended June 30, 2005. As a percentage of net sales, selling, general and administrative expenses decreased to 12.8% in the nine
months ended June 30, 2006 from 13.6% in the nine months ended June 30, 2005. The nine months ended June 30, 2006 includes stock-based compensation expense under SFAS 123R of approximately $1.9 million and the nine months ended
June 30, 2005 includes stock-based compensation of approximately $0.7 million. The nine months ended June 30, 2005 included a $1.1 million write-off of excess facility space in our Santa Clara headquarters. Excluding the impact of SFAS
123R in the nine months ended June 30, 2006 and the $1.1 million write-off in the nine months ended June 30, 2005, the increase in selling, general and administrative expenses was primarily attributable to our consolidation of ICSI.

Acquired in-process technology charge. In the nine months ended June 30, 2006, we incurred a $0.5 million acquired in-process
technology charge (IPR&D) in connection with our purchase of additional shares of ICSI. The valuation and purchase allocation is preliminary and is subject to further adjustment. The $0.5 million allocated to IPR&D was expensed in the nine
months ending June 30, 2006 as it was deemed to have no future alternative use. The $1.9 million allocated to IPR&D in the nine months ending June 30, 2005 related to our acquisition of ICSI shares in the June 2005 quarter and Signia
in December 2004.

Interest and other income (expense), net. Interest and other income (expense), net was $3.4 million in the nine
months ended June 30, 2006 compared to $2.3 million in the nine months ended June 30, 2005. The $3.4 million of interest and other income (expense), net in the nine months ended June 30, 2006 is comprised primarily of interest income
of $2.0 million, $0.5 million from the sale of assets from our Bluetooth business in the March 2006 quarter and $0.3 million in foreign currency exchange gains. The $2.3 million of interest and other income (expense) in the nine months ended
June 30, 2005 was comprised primarily of interest income. In addition, in the nine months ended June 30, 2005, we recorded a gain of approximately $0.5 million from the sale of fixed assets.

Gain on sale of investments.The gain on the sale of investments was $2.5 million in the nine
months ended June 30, 2006 compared to $3.4 million in the nine months ended June 30, 2005. In the nine months ended June 30, 2006, we sold our investment in E-CMOS for approximately $1.5 million which resulted in a pre-tax gain of
$0.3 million. In addition, we sold approximately 77% of our investment in Signia for approximately $4.6 million which resulted in a pre-tax gain of $2.2 million. As a result of the sale of the Signia shares, we reduced our ownership percentage to
approximately 16% and effective March 2006 account for Signia on the cost basis. The deconsolidation of Signia did not have a material impact on our balance sheet and will not have a material effect on our revenue or earnings per share. In the nine
months ended June 30, 2005, we sold shares of SMIC for approximately $5.6 million which resulted in a pre-tax gain of $2.9 million. In addition, we sold our investment in NexFlash for approximately $2.2 million which resulted in a pre-tax gain
of $0.5 million.

Provision for income taxes.The provision for income taxes for the nine month period ended June 30, 2006 of
$164,000 consists primarily of foreign withholding taxes and taxes in foreign jurisdictions. The provision for income taxes for the nine month period ended June 30, 2005 of $26,000 consists solely of foreign withholding taxes.

Minority interest in net loss of consolidated subsidiaries.The minority interest in net loss of consolidated subsidiaries was
$0.7 million in the nine months ended June 30, 2006 compared to $0.6 million in the nine months ended June 30, 2005. The minority interest in net loss of consolidated subsidiaries for the nine months ended June 30, 2006 represents the
minority shareholders proportionate share of the net loss of ICSI for such period and the minority shareholders proportionate share of the net loss of Signia for the five months ended February 28, 2006. Effective March 2006, we
account for Signia on the cost basis. The minority interest in net loss of consolidated subsidiaries for the nine months ended June 30, 2005 represents the minority shareholders proportionate share of the net loss of Signia for the seven
months ended June 30, 2005 and the minority shareholders proportionate share of the net loss of ICSI for the two months ended June 30, 2005.

Equity in net loss of affiliated companies.Equity in net loss of affiliated companies was $0.7 million in the nine months ended June 30, 2006 compared to a $11.8 million loss in the nine months ended
June 30, 2005. In the nine months ended June 30, 2006, we recorded a loss of approximately $0.7 million related to our equity interest in KSC. In the nine months ended June 30, 2005, we recorded a loss of approximately $11.8 million
related primarily to our equity interest in ICSI prior to our consolidation of ICSIs financial results effective May 1, 2005.

Liquidity and
Capital Resources

As of June 30, 2006, our principal sources of liquidity included cash, cash equivalents and short-term
investments of approximately $117.2 million. During the nine months ended June 30, 2006, operating activities used cash of approximately $2.8 million compared to $2.7 million used in the nine months ended June 30, 2005. The cash used by
operations was primarily due to our net loss of $14.4 million adjusted for non-cash items of $4.8 million (gain on the sale of Signia shares of $(2.2) million, gain on the sale of assets of $(0.5) million, gain on the sale of E-CMOS of
$(0.3) million, stock-based compensation expense of $3.6 million, equity in net loss of affiliated companies of $0.7 million, depreciation and amortization of $2.8 million, amortization of intangibles of $1.3 million, acquired in-process technology
charge of $0.5 million and other non-cash items of $(1.0) million) and decreases in accounts payable of $2.9 million. This was partially offset by decreases in inventories of $6.3 million, decreases in accounts receivable of $0.3 million, and
increases in accrued expenses of $2.7 million and other liabilities of $0.3 million.

In the nine months ended June 30, 2006, we
generated $8.9 million from investing activities compared to $44.2 million generated in the nine months ended June 30, 2005. The cash generated from investing activities in the nine months ended June 30, 2006 primarily resulted from net
sales of available-for-sale securities of $17.0 million. In addition, during the nine months ended June 30, 2006, we generated $1.5 million from the sale of our investment in E-CMOS resulting in a pre-tax gain of approximately $0.3 million,
$4.6 million from the sale of Signia shares resulting in a pre-tax gain of approximately $2.2 million (which was offset by $0.1 million from the deconsolidation of Signia) and $1.1 million from the sale of Bluetooth and other assets. We used
approximately $13.9 million in the nine months ended June 30, 2006 for the purchase of additional shares of ICSI. The cash generated from investing activities in the nine months ended June 30, 2005 primarily resulted from net sales of
available-for-sale securities of $67.3 million. In addition, in the nine months ended June 30, 2005, we generated approximately $5.6 million from the sale of additional shares of SMIC, resulting in a pre-tax gain of approximately $2.9 million.
In addition, in the nine months ended June 30, 2005, we generated approximately $2.2 million from the sale of shares of NexFlash (which included the $0.5 million of NexFlash shares purchased in the March 2005 quarter) resulting in a pre-tax
gain of approximately $0.5 million and approximately $0.5 million from the sale of fixed assets.

##### Table of Contents

We used approximately $6.8 million for our additional investment in Signia and approximately $23.2 million for our additional investment in ICSI which was
comprised of cash used for the purchase of ICSI shares of $31.6 million less cash acquired as a result of our consolidation of ICSI of $8.4 million.

In the nine months ended June 30, 2006, we made capital expenditures of approximately $1.3 million for test equipment and engineering tools. We expect to spend approximately $1.0 million to $3.0 million to
purchase capital equipment during the next twelve months, principally for the purchase of design and engineering tools, additional test equipment, and computer software and hardware. We expect to fund our capital expenditures from our existing cash
and cash equivalent balances.

We generated $3.5 million from financing activities during the nine months ended June 30, 2006 compared
to $12.7 million used in the nine months ended June 30, 2005. In the nine months ended June 30, 2006, we used $53.8 million for the repayment of short-term borrowings. Our sources of financing for the nine months ended June 30, 2006
were borrowings of $55.7 million under ICSI lines of credit, proceeds from the issuance of common stock of $1.4 million from stock option exercises and sales under our employee stock purchase plan and a decrease in restricted cash of $0.2 million.
In the nine months ended June 30, 2005, we used $15.0 million to pay convertible debentures and $1.8 million to repay short-term debt acquired in the consolidation of ICSI. The sources of financing for the nine months ended June 30, 2005
were proceeds from the issuance of common stock of $2.2 million from stock option exercises and sales under our employee stock purchase plan and a decrease in restricted cash of $1.2 million and borrowings of $0.6 million under ICSI lines of credit.

We have $21.1 million available through a number of short-term lines of credit with various financial institutions in Taiwan. These lines
of credit expire at various times through April 2007. As of June 30, 2006, we had outstanding borrowings of approximately $8.8 million under these short-term lines of credit. We guaranteed the borrowings of ICSI under a line of credit with a
bank in Taiwan for a maximum amount of approximately $4.9 million through January 2007. As of June 30, 2006, $3.1 million was outstanding under this line of credit. Our unused short-term lines of credit and unused lines of credit for short-term
notes amounted to approximately $10.8 million and $1.5 million, respectively, at June 30, 2006.

Our headquarters are located in a
leased site in San Jose, California. Outside of the U.S., we have operations in leased sites in China and Hong Kong. In addition to these sites, we lease sales offices in the U.S., Europe and Asia. These leases expire at various dates through 2009.
In Taiwan, we own and occupy the ICSI building. The land upon which the ICSI building is situated is leased under an operating lease that expires in March 2016. Our outstanding commitments under these leases were approximately $3.6 million at
June 30, 2006.

We generally warrant our products against defects in materials and workmanship for a period of 12 months. Liability
for a stated warranty period is usually limited to the replacement of defective items or return of amounts paid. Warranty expense has historically been immaterial to our financial statements.

We believe our existing funds will satisfy our anticipated working capital and other cash requirements through at least the next 12 months. We may, from
time to time, take actions to further increase our cash position through equity or debt financings, sales of shares of investments, bank borrowings, or the disposition of certain assets. From time to time, we may also commit to acquisitions or
equity investments, including strategic investments in wafer fabrication foundries or assembly and test subcontractors. To the extent we enter into such transactions, we may need to seek additional equity or debt financing to fund such activities.
There can be no assurance that any such additional financing could be obtained on terms acceptable to us, if at all.

Off-Balance Sheet Arrangements

As of June 30, 2006, we did not have any off-balance sheet arrangements as defined in Item 303 (a)(4)(ii) of SEC
Regulation S-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our financial market risk includes
foreign currency transactions, exposure to changes in interest rates on our fixed rate debt, our investments in marketable equity securities and our investments in private companies.

We anticipate that international sales will continue to account for a significant portion of our consolidated revenue. Our international sales are
largely denominated in U.S. dollars and therefore are not subject to material foreign currency exchange risk. However, we have operations in China, Europe, Taiwan, Hong Kong, India, Japan and Korea where expenses are denominated in each
countrys local currency and are subject to foreign currency exchange risk. In the nine months ended June 30, 2006, we recorded exchange gains of approximately $0.3 million. However, in the quarter ended September 30, 2005, we
recorded exchange losses of approximately $0.9 million. Prior to this we had not experienced any significant negative impact on our operations as a result of fluctuations in foreign currency exchange rates. We do not currently engage in any hedging
activities.

We had cash, cash equivalents and short-term investments of $79.7 million at June 30, 2006 excluding $37.5 million of
SMIC stock included in short-term investments. The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without increasing risk. We invest primarily in high-quality, short-term debt
instruments such as municipal auction rate certificates and instruments issued by high quality financial institutions and companies, including money market instruments. A hypothetical one percentage point decrease in interest rates would result in
approximately a $0.8 million decrease in our interest income. As our portfolio consists mainly of short-term investments whose interest rates reset, a hypothetical one percentage point change in interest rates would not have a material affect on the
value of our investments.

We own ordinary shares in SMIC which has been a publicly traded company since March 2004. SMICs ordinary
shares are traded on the Hong Kong Stock Exchange and SMIC American Depository Receipts (ADR) are traded on the New York Stock Exchange. Each SMIC ADR represents fifty (50) ordinary shares. We use the weighted-average cost method to
determine the cost basis of shares of SMIC. In fiscal 2005, we sold shares of SMIC and recorded gross proceeds of approximately $8.7 million and a pre-tax gain of approximately $4.4 million. Since SMICs IPO, we account for our shares in SMIC
under the provisions of FASB 115 and mark the shares to the market value with the offset recorded in accumulated other comprehensive income. The cost basis of our shares in SMIC is approximately $30.3 million and the market value at June 30,
2006 was approximately $37.5 million. The market value of SMIC shares is subject to fluctuations and our carrying value will be subject to adjustments to reflect changes in SMICs market value in future periods. In the event the market value of
our SMIC shares declines below our cost basis, and the decline is other-than-temporary, we may be required to recognize a loss on our investment through operating results. Our shares in SMIC are subject to certain lockup restrictions and therefore
are not freely tradable. These lockup restrictions generally lapse at the rate of 15% of our pre-offering shares every 180 days following SMICs IPO in March 2004. Thus, all of our shares in SMIC have been freely tradable only since February
2007. Through June 30, 2006, these lockup restrictions impacted our ability to sell the locked up portion of our SMIC shares.

We have
investments in equity securities of privately held companies of approximately $3.5 million at June 30, 2006. These investments are generally in companies in the semiconductor industry. These investments are included in other assets and are
accounted for using the equity or cost method. For investments in which no public market exists, our policy is to review the operating performance, recent financing transactions and cash flow forecasts for such companies in assessing whether our
investments in these companies are impaired below our cost basis. Impairment losses on equity investments are recorded when events and circumstances indicate that such assets are impaired and the decline in value is other than temporary. In this
regard, we recorded approximately $0.3 million impairment losses on two equity investments in fiscal 2005.

Item 4. Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer, based on the
evaluation of our disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended) required by paragraph (b) of Rule 13a-15 or Rule 15d-15, have concluded that, as of
June 30, 2006, our disclosure controls and procedures were effective to ensure that the information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and
reported within the time periods specified in Securities and Exchange Commission rules and forms. During the three months ended June 30, 2006, there was no change in our internal control over financial reporting identified in connection with
the evaluation required by paragraph (d) of Rule 13a-15 or Rule 15d-15 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting except that certain of the remedial actions
described below had been implemented or were in the process of being implemented during such period.

Stock Option Grant Practices and Restatement

As discussed in Note 2 Restatement of Consolidated Financial Statements to Condensed Consolidated Financial Statements and
in Item 2, Managements Discussion and Analysis of Financial Condition and Results of Operation. of this Form 10-Q, during fiscal year 2006, an independent investigation related to our historical stock option granting practices
was carried out by a Special Committee of our Board of Directors. As a result of the investigation, we reached the conclusion that incorrect measurement dates were used for financial accounting purposes for certain stock option grants made in prior
periods. Therefore, we have recorded additional non-cash stock-based compensation expense with regard to past stock option grants. In our 2006 Form 10-K, we are restating our consolidated balance sheet as of September 30, 2005, and the related
consolidated statements of operations, shareholders equity, and cash flows for each of the fiscal years ended September 30, 2005 and September 30, 2004. We are also restating the unaudited quarterly financial information for all
interim periods of fiscal year 2005 and the interim periods ended December 31, 2005 and March 31, 2006 in our 2006 Form 10-K for the year ended September 30, 2006.

Remedial Measures

As a result of this investigation, we identified a material weakness in our
internal control over financial reporting related to our stock option granting practices and the related accounting in periods ending prior to March 31, 2006.

Before March 2006, we did not have sufficient safeguards in place to monitor our control practices regarding stock option pricing and related financial reporting, the result of which is discussed in Item 1, Note
2 and Item 2 of this report. Beginning in March 2006, we standardized and formalized the procedure for granting awards of stock options to employees and to executive officers. In addition, management, along with our Board of Directors, has
implemented or is in the process of implementing the following internal control systems and procedures, which were recommended by the Special Committee:



| | 1. | Limit authority to approve grants and any amendments to outstanding grants to members of the Board of Directors or the Compensation Committee (i.e., eliminate the Stock Option
Committee).
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Establish fixed dates, in advance, on which all equity grants are to be made. Avoid dates near earnings announcements and off-cycle exception grants. For new hires, grants must be
made following their actual commencement of employment.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | Grant only at in person or telephonic meetings of the Board or Compensation Committee that occur before the predetermined grant dates and not through unanimous written consent
actions. The Compensation Committee should meet monthly or every other month.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. | Complete all grant documentation before the predetermined grant dates and circulate information to those approving the grants prior to the meeting. If there are any changes to the
grants resulting from the meeting, the changes will be documented.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5. | Provide for participation by legal personnel (external counsel) in Board and Compensation Committee meetings and timely and accurately communicate Board and Compensation actions to
responsible human resources, finance, and stock administration personnel.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| | 6. | Ensure the completion and execution of Board and Compensation Committee minutes promptly after meetings, and approve them at the following Board or Compensation Committee meeting,
as applicable.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7. | Establish controls to prohibit any revisions to lists of approved grants or modification of equity grants, whether direct or indirect (i.e., through adoption of separate individual
agreements which impact outstanding grants), including termination arrangements providing for accelerated vesting or extended vesting or exercising of options, without prior review by representatives of human resources, finance and legal and
approval by the Board or Compensation Committee.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 8. | Timely communicate material terms of grants to recipients following their effective date of grant.
| | -- | --------------------------------------------------------------------------------------------------



| | 9. | Maintain all documentation related to equity grant approval centrally (e.g., Compensation Committee minutes). One person should be responsible for entering stock option grants into
the equity tracking software program, and a second person should review the input in a timely manner to guard against errors. Grants should be entered into the system shortly after they are made, rather than at end of each quarter. Grant lists
should be marked to indicate the dates on which they become final, and the stock administrator should indicate the date on which grant lists and other relevant documents are received, so as to provide an appropriate audit trail.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 10. | Establish written policies and procedures for equity grants, vesting, exercises, sales and recordkeeping consistent with the above that have been approved jointly by representatives
from finance and human resources (including stock administration personnel) and discussed with the Compensation Committee.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 11. | Monitor any guidance regarding equity grant procedures from the SEC and the public accounting community, to make sure procedures are in compliance.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------



| | 12. | Implement annual formal review of stock option documentation, including plan documents, agreements, and approving resolutions, to ensure compliance and understanding of material
terms by representatives of finance, human resources and stock administration personnel. Any proposed amendments to plan documents should be reviewed by finance, human resources and stock administration personnel before approval by Board.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 13. | Establish regular training programs for stock administration, human resources, and finance personnel, covering the equity grant process and proper accounting. Provide for active
involvement of external legal counsel or other appropriate experts in training and review of the equity grant process.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 14. | Establish and proactively monitor internal controls regarding the equity grant process, including the IT processes involved in grant procedures. Ensure that full audit functionality
of equity tracking software is understood and employed and kept up to date.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 15. | Establish and proactively monitor internal controls regarding cash exercises of stock options to ensure that such exercises and payments therefore are fully and accurately
documented, all necessary approvals are obtained and documented, and such exercises are accurately and timely entered into the Equity Edge tracking software system.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 16. | Ensure that our disclosure controls adequately address the processes for making, recording, disclosing and accounting for equity grants and exercises of such grants.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

We believe that the changes made in March 2006 remediated the past material weakness in our internal control over financial
reporting related to our stock option granting practices and the related accounting, and reduced to remote the likelihood that any incorrect measurement dates or any material error in accounting for stock options could have occurred during fiscal
year 2006 and not been detected as part of our financial reporting close process.

Part II. OTHER INFORMATION

Item 1. Legal Proceedings

We are subject to various legal proceedings and claims as discussed below.
In addition, in the ordinary course of our business, we have been involved in a limited number of legal actions, both as plaintiff and defendant, and could incur uninsured liability in any one or more of them. Although the outcome of these
actions is not presently determinable, we believe that the ultimate resolution of these matters will not harm our business and will not have a material adverse effect on our financial position, cash flows or results of operations. Litigation
relating to the semiconductor industry is not uncommon, and we are, and from time to time have been, subject to such litigation. No assurances can be given with respect to the extent or outcome of any such litigation in the future.

Shareholder Derivative Actions

On
July 18, 2006 and July 26, 2006, two purported shareholder derivative actions were filed against certain current and former directors and officers of ISSI in the United States District Court for the Northern District of California,
entitled (1) Rick Tope v. Jimmy S.M. Lee, et al., Case No. C06-04387, and (2) Murray Donnelly v. Jimmy S.M. Lee, et al., Case No. C06-04545. The complaints purport to assert claims against the individual defendants on behalf
of ISSI for breach of fiduciary duty, violations of Section 10(b) of the Securities Exchange Act of 1934 (Exchange Act) and Rule 10b-5 promulgated thereunder, unjust enrichment, and restitution based upon our alleged stock option
grant practices from 1995 through 2002. We are named solely as a nominal defendant. The complaints seek damages in an unspecified amount against the individual defendants, disgorgement of stock options or proceeds, equitable relief, attorneys
fees, and other unspecified relief. Pursuant to the parties stipulation, the Court consolidated the two derivative actions on August 22, 2006, under the caption In re Integrated Silicon Solution, Inc. Shareholder Derivative
Litigation, Master File No. C-06-04387 RMW. Plaintiffs filed a consolidated shareholder derivative complaint on November 27, 2006, based upon the same underlying facts and circumstances alleged in the prior complaints. In addition to the
claims asserted and the relief sought in the original complaints, the consolidated complaint purports to assert claims against the individual defendants for aiding and abetting and violating Sections 14(a) and 20(a) of the Exchange Act and seeks an
accounting. We are again named solely as a nominal defendant.

On October 31, 2006, another purported shareholder derivative action
was filed against certain current and former directors and officers of ISSI in the Superior Court of California for the County of Santa Clara, entitled Alex Chuzhoy v. Jimmy S.M. Lee, et al., Case No. 1:06-CV-074031. The complaint
purports to assert claims against the individual defendants on behalf of ISSI for insider trading in violation of California Corporations Code Sections 25402 / 25502.5, breach of fiduciary duty including in connection with the alleged insider
selling and misappropriation, abuse of control, gross mismanagement, constructive fraud, corporate waste, unjust enrichment, and rescission, based upon our alleged stock option grant practices from 1995 through 2002. We are named solely as a nominal
defendant. The complaint seeks damages in an unspecified amount against the individual defendants, an accounting, certain corporate governance changes, a constructive trust over the defendants stock options or proceeds, punitive damages,
attorneys fees, and other unspecified relief.

Plaintiffs in the state and federal derivative complaints will amend their complaints
after we conclude our financial restatement. Defendants intend to move to dismiss both the state and federal complaints.

Nasdaq Delisting

On August 17, 2006, we received a letter from The NASDAQ Stock Market indicating that we were not in compliance with the
NASDAQ requirements for continued listing set forth in NASDAQ Marketplace Rule 4310(c)(14), and faces a possible delisting. On December 7, 2006, following a hearing before the Nasdaq Listing Qualifications Panel (Panel), the Panel
notified us that we would remain listed on Nasdaq subject to the filing by February 13, 2007 of all required restatements and delinquent periodic reports, communication with the Panel about the results of the independent committees
investigation, and compliance with all other requirements for continued listing on the Nasdaq Stock Market. We also received a letters from The NASDAQ Stock Market indicating that as a result of our failure to timely file our Form 10-K for the
fiscal year ended September 30, 2006 and our Form 10-Qs for the quarters ended December 31, 2006 and March 31, 2007, we were not in compliance with the NASDAQ requirements for continued listing set forth in NASDAQ Marketplace
Rule 4310(c)(14).

##### Table of Contents

On January 19, 2007, the Nasdaq Listing and Hearing Review Council (Listing Council)
notified us that, pursuant to its discretionary authority, it had called for review the December 7, 2006 decision of the Panel and stayed any determinations to suspend our securities from trading pending further action by the Listing Council.
On May 9, 2007, we were advised by the Listing Council that we would remain listed on NASDAQ if we conclude our restatement and file our delinquent required SEC filings by June 5, 2007.

SRAM Antitrust Litigation

Thirty-two
purported class action lawsuits were filed against us and other SRAM suppliers in various U.S. federal courts alleging violations of the Sherman Act, violations of state unfair competition laws, and unjust enrichment relating to the sale and pricing
of SRAM products. The U.S. lawsuits have been consolidated in a single federal court for coordinated pre-trial proceedings. The U.S. complaints seek treble damages for the alleged damages sustained by purported class members, in addition to
restitution, costs and attorneys fees, as well as an injunction against the allegedly unlawful conduct. Two purported class action lawsuits were filed against us and other SRAM suppliers in two Canadian courts alleging violation of the
Canadian Competition Act and unlawful conduct at common law. The Canadian complaints seek compensatory and punitive damages, in addition to declaratory relief, restitution, and costs. We are committed to defending ourself against these claims
and have instructed our counsel to contest these actions vigorously. Given the preliminary stage of these proceedings and the inherent uncertainty in litigation, we are unable to predict the outcome of these suits. The final resolution of these
alleged violations of federal or state antitrust laws could have a material adverse effect on our business, results of operations, or financial condition.

SRAM Antitrust Civil Investigative Demand

In May 2007, we received a civil investigative demand (CID)
from the Attorney General of the State of Florida. The CID is issued pursuant to the Florida Antitrust Act in the course of an official investigation to determine whether there is, has been, or may be a violation of state or federal antitrust laws.
Although not alleging any wrongdoing, the CID seeks documents and data relating to our business. We intend to cooperate fully with the Attorney General of Florida in this investigation. Because the investigation is at an early stage, we cannot
predict the outcome of the investigation and its effect, if any, on our business.

Item 1A. Risk Factors

We have been named as a party to several lawsuits related to our historical stock option
practices and related accounting, we may be named in additional litigation in the future and we are the subject of a formal SEC investigation, all of which could result in an unfavorable outcome and have a material adverse effect on our business,
financial condition, results of operations, cash flows and the trading price for our securities.

Several lawsuits have been filed
against certain of our current directors and officers and our former directors and officers relating to our historical stock option practices and related accounting; we are named as nominal defendant in such matters. We are also subject to a formal
SEC investigation with respect to such matters. See Item 1Legal Proceedings for a more detailed description of these proceedings. We may become the subject of additional private or government actions regarding these matters in the
future. These actions are in the preliminary stages, and their ultimate outcome could have a material adverse effect on our business, financial condition, results of operations, cash flows and the trading price for our securities. Litigation may be
time-consuming, expensive and disruptive to our normal business operations, and the outcome of litigation is difficult to predict. The defense of these lawsuits has resulted and will continue to result in significant legal and accounting
expenditures and the continued diversion of our managements time and attention from the operation of our business. All or a portion of any amount we may be required to pay to satisfy a judgment or settlement of any or all of these claims may
not be covered by insurance.

We have entered into indemnification agreements with each of our present and former directors and officers.
Under those agreements, we are required to indemnify each such director or officer against expenses, including attorneys fees, judgments, fines and settlements, paid by such individual in connection with the pending litigation subject to
applicable Delaware law.

If we do not maintain compliance with the listing requirements of the NASDAQ Global Market, our common stock could be
delisted, which could, among other things, reduce the price of our common stock and the levels of liquidity available to our stockholders.

In connection with the restatement of our financial statements, we were delinquent in filing certain of our periodic reports with the SEC, and consequently we were not in compliance with the listing requirements under the NASDAQ Global
Markets Marketplace Rules. Upon the filing of this Quarterly Report on Form 10-Q, our Annual Report on Form 10-K for the year ended September 30, 2006 and our Quarterly Reports on Form 10-Q for the periods ended December 31, 2006 and
March 31, 2007, we believe that we will be in compliance with the NASDAQ listing standards. However, our securities could be delisted in the future if we do not maintain compliance with applicable listing requirements. If our securities are
delisted from the NASDAQ Global Market, they would subsequently be transferred to the National Quotation Service Bureau, or Pink Sheets. The trading of our common stock on the Pink Sheets may reduce the price of our common stock and the
levels of liquidity available to our stockholders. If we are delisted in the future from the NASDAQ Global Market and transferred to the Pink Sheets, there may also be other negative implications, including the potential loss of confidence by
suppliers, customers and employees and the loss of institutional investor interest in our company.

We have incurred significant losses in certain
recent periods, and there can be no assurance that we will be able to achieve or sustain profitability in the future.

We incurred
losses of $14.4 million in the first nine months of fiscal 2006, which included inventory write-downs of $14.3 million. We incurred losses of $39.8 million in fiscal 2005, which included inventory write-downs of $13.9 million, charges of
$11.7 million related to our equity interest in ICSI, charges on impairment of goodwill and investments of $4.7 million and charges for in-process R&D of $2.8 million. Though we were profitable in the first three quarters of fiscal
2004, we incurred a loss in the fourth quarter of fiscal 2004, which included an inventory write-down of $12.1 million. There is no assurance that we will achieve or maintain profitability in subsequent quarters. Our ability to achieve and maintain
profitability on a quarterly or fiscal year basis in the future will depend on a variety of factors, including the need for future inventory write-downs, our ability to increase net sales, maintain or expand gross margins, introduce new products on
a timely basis, secure sufficient wafer fabrication capacity and control operating expenses, including stock-based compensation as required by SFAS 123R. Adverse developments with respect to these or other factors could result in quarterly or annual
operating losses in the future.

Our operating results are expected to continue to fluctuate and may not meet our financial guidance or published
analyst forecasts. This may cause the price of our common stock to decline significantly.

Our future quarterly and annual operating
results are subject to fluctuations due to a wide variety of factors, including:



| |  |  | the cyclicality of the semiconductor industry;
| | - |  | ----------------------------------------------



| |  |  | declines in average selling prices of our products;
| | - |  | ---------------------------------------------------



| |  |  | inventory write-downs for lower of cost or market or excess and obsolete;
| | - |  | -------------------------------------------------------------------------



| |  |  | excess inventory levels at our customers;
| | - |  | -----------------------------------------



| |  |  | decreases in the demand for our products;
| | - |  | -----------------------------------------



| |  |  | oversupply of memory products in the market;
| | - |  | --------------------------------------------



| |  |  | our ability to control or reduce our operating expenses;
| | - |  | --------------------------------------------------------



| |  |  | shortages in foundry, assembly or test capacity;
| | - |  | ------------------------------------------------



| |  |  | disruption in the supply of wafers, assembly or test services;
| | - |  | --------------------------------------------------------------

Our sales depend on DRAM and SRAM products and reduced demand for these products or a decline in average selling prices could harm our business.

In the nine months ended June 30, 2006 and in fiscal 2005, approximately 92% and 88%, respectively, of our net sales were derived from the sale of
DRAM and SRAM products, which are subject to unit volume fluctuations and declines in average selling prices that could harm our business. For example, we experienced a sequential decline in revenue from $61.5 million in our September 2005 quarter
to $51.1 million in our December 2005 quarter. This decline in revenue was primarily the result of a decrease in unit shipments and the average selling prices of our DRAM products. In the December 2005 quarter, we turned down some orders for DRAM
products that had unfavorable margins as a result of the decrease in the average selling prices in the market. We may not be able to offset any future price declines for our products by higher volumes or by higher prices on newer products.
Historically, average selling prices for semiconductor memory products have declined, and we expect that average selling prices for our products will decline in the future. Our ability to maintain or increase revenues will depend upon our ability to
increase unit sales volume of existing products and introduce and sell new products that compensate for the anticipated declines in the average selling prices of our existing products.

We are subject to pending legal proceedings related to the SRAM market.

We have been named as a
defendant in a number of civil antirust complaints filed against semiconductor companies on behalf of purported classes of direct and indirect purchasers of SRAM products throughout the United States. The complaints allege that the defendants
conspired to raise the price of SRAM in violation of Section 1 of the Sherman Act, the California Cartwright Act, and several other State antitrust, unfair competition and consumer protection statutes. We believe that we have meritorious
defenses to the allegations in the complaints, and we intend to defend these lawsuits vigorously. However, the litigation is in the preliminary stage and we cannot predict its outcome. Multidistrict antitrust litigation is particularly complex and
can extend for a protracted time, which can substantially increase the cost of such litigation. The defense of these lawsuits is also expected to divert the efforts and attention of some of our key management and technical personnel. As a
result, our defense of this litigation, regardless of its eventual outcome, will likely be costly and time consuming. Should the outcome of the litigation be adverse to us, we could be required to pay significant monetary damages, which could
adversely affect our business, financial condition, operating results and cash flows.

Any future downturn in the markets we serve would harm our business and financial results.

Substantially all of our products are incorporated into products for the digital consumer electronics, networking, mobile communications and automotive
electronics markets. Historically, these markets have experienced cyclical depressed business conditions, often in connection with, or in anticipation of, a decline in general economic conditions or due to adverse supply and demand conditions in
such markets. Industry downturns have resulted in reduced demand and declining average selling prices for our products which adversely affected our business. We expect that our industry will remain cyclical, and we are unable to predict when any
upturn or downturn will occur or how long it will last.

Shifts in industry-wide capacity may cause our results to fluctuate. These shifts may occur
quickly with little or no advance notice. Such shifts have historically resulted in significant inventory write-downs.

The
semiconductor industry is highly cyclical and is subject to significant downturns resulting from excess capacity, overproduction, reduced demand or technological obsolescence. Shifts in industry-wide capacity from shortages to oversupply or from
oversupply to shortages may result in significant fluctuations in our quarterly or annual operating results. These shifts in industry conditions can occur quickly with little or no advance notice to us. Adverse changes in industry conditions are
likely to result in a decline in average selling prices and the stated value of inventory. In the first nine months of fiscal 2006, in fiscal 2005 and in fiscal 2004, we recorded inventory write-downs of $14.3 million, $13.9 million and $17.3
million, respectively. The inventory write-downs related to valuing our inventory at the lower-of-cost-or-market, and adjusting our inventory valuation for certain excess and obsolete products.

We write down to zero dollars the carrying value of inventory on hand in excess of six months historical sales volumes to cover estimated excess
and obsolete exposures, unless adjustments are made based on managements judgments for newer products, end of life products, planned inventory increases or strategic customer supply. In making such judgments to write down inventory, management
takes into account the product life cycles which can range from six to 30 months, the stage in the life cycle of the product, the impact of competitors announcements and product introductions on our products.

We believe that six months is an appropriate period because it is difficult to accurately forecast for a specific product beyond this time frame due to
the potential introduction of products by competitors, technology obsolescence or fluctuations in demand. Future additional inventory write-downs may occur due to lower of cost or market accounting, excess inventory or inventory obsolescence.

Our transition to lead-free parts may result in excess inventory of products packaged using traditional methods.

Customers are requiring that we offer our products in lead-free packages. Governmental regulations in certain countries and customers intention to
produce products that are less harmful to the environment has resulted in a requirement from many of our customers to purchase integrated circuits that do not contain lead. We have responded by offering our products in lead-free versions. While the
lead-free versions of our products are expected to be more friendly to the environment, the ultimate impact is uncertain. The transition to lead-free products may produce sudden changes in demand depending on the packaging method used, which may
result in excess inventory of products packaged using traditional methods. This may have an adverse effect on our results of operations. In addition, the quality, cost and manufacturing yields of the lead-free parts may be less favorable to us than
the products packaged using more traditional materials which may result in higher product costs.

If we are unable to obtain an adequate supply of
wafers, our business will be harmed.

If we are unable to obtain an adequate supply of wafers from our current suppliers or any
alternative sources in a timely manner, our business will be harmed. Our principal manufacturing relationships are with Powerchip Semiconductor, SMIC, Taiwan Semiconductor Manufacturing Corporation (TSMC) and Chartered Semiconductor Manufacturing.
Each of our wafer foundries also supplies wafers to other semiconductor companies, including certain of our competitors or for their own account. Although we are allocated specific wafer capacity from our suppliers, we may not be able to obtain such
capacity in periods of tight supply. If any of our suppliers experience manufacturing failures or yield shortfalls, choose to prioritize capacity for other uses, or reduce or eliminate deliveries to us, we may not be able to obtain enough wafers to
meet the market demand for our products which would adversely affect our revenues. Once a product is in production at a particular foundry, it is time consuming and costly to have such product manufactured at a different foundry. In addition, we may
not be able to qualify additional manufacturing sources for existing or new products in a timely manner and we cannot be certain that other manufacturing sources would be able to deliver an adequate supply of wafers to us or at the same cost.

Our gross margins may decline even in periods of increasing revenue.

Our gross margin is affected by a variety of factors, including our mix of products sold, average selling prices for our products and cost of wafers. Even
when our revenues are increasing, our gross margin may be adversely affected if such increased revenue is from products with lower margins or declining average selling prices. During periods of strong demand, wafer capacity is likely to be in short
supply and we will likely have to pay higher prices for wafers, which would adversely affect our gross margin unless we are able to increase our product prices to offset such costs. To maintain our gross margins when average selling prices are
declining, we must introduce new products with higher margins or reduce our cost per unit. There can be no assurance that we will be able to increase unit sales volumes, introduce and sell new products or reduce our cost per unit.

We may encounter difficulties in effectively integrating newly acquired businesses.

From time to time, we intend to acquire other companies or assets that we believe to be complementary to our business. Acquisitions may result in use of our cash resources, potentially dilutive issuances of equity
securities, incurrence of debt and contingent liabilities, amortization expenses related to intangible assets, and the possible impairment of goodwill, which could harm our profitability. In addition, acquisitions involve numerous risks, including:



| |  |  | higher than estimated acquisition expenses;
| | - |  | -------------------------------------------



| |  |  | difficulties in successfully assimilating the operations, technologies and personnel of the acquired company;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in continuing to develop the new technologies and deliver products to market on time;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | diversion of managements attention from other business concerns;
| | - |  | -----------------------------------------------------------------



| |  |  | risks of entering markets in which we have no, or limited, direct prior experience;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the risk that the markets for acquired products do not develop as expected; and
| | - |  | -------------------------------------------------------------------------------



| |  |  | the potential loss of key employees and customers as a result of the acquisition.
| | - |  | ---------------------------------------------------------------------------------

In this regard, in February 2006, we sold our shares of Signia as we decided to exit the Bluetooth market and focus on our core product strategy. We sold
approximately 77% of our investment in Signia for approximately $4.6 million which resulted in a pre-tax gain of $2.2 million. As a result of the sale of the Signia shares, we reduced our ownership percentage to approximately 16% and effective March
2006 account for Signia on the cost basis. For the period ending September 30, 2005, we incurred an impairment charge of $4.4 million related to the goodwill acquired with Signia. There is no assurance that any future acquisitions will
contribute positively to our business or operating results.

We rely on third-party contractors to assemble and test our products and our failure to
successfully manage our relationships with these contractors could damage our relationships with our customers, decrease our sales and limit our growth.

We rely on third-party contractors located in Asia to assemble and test our products. There are significant risks associated with our reliance on these third-party contractors, including:



| |  |  | reduced control over product quality;
| | - |  | -------------------------------------



| |  |  | potential price increases;
| | - |  | --------------------------



| |  |  | reduced control over delivery schedules;
| | - |  | ----------------------------------------



| |  |  | possible capacity shortages;
| | - |  | ----------------------------



| |  |  | their inability to increase production and achieve acceptable yields on a timely basis;
| | - |  | ---------------------------------------------------------------------------------------

| |  |  | absence of long-term agreements;
| | - |  | --------------------------------



| |  |  | limited warranties on products supplied to us; and
| | - |  | --------------------------------------------------



| |  |  | general risks related to conducting business internationally.
| | - |  | -------------------------------------------------------------

If any of these risks are realized, our business and results of operations could be adversely affected until our subcontractor is able to remedy the problem or until we are able to secure an alternative subcontractor.

The loss of a significant customer or a reduction in orders from one or more large customers could adversely affect our operating results.

As sales to our customers are executed pursuant to purchase orders and no purchasing contracts typically exist, our customers can cease
doing business with us at any time. We may not be able to retain our key customers, such customers may cancel or reschedule orders, and in the event of canceled orders, such orders may not be replaced by other sales. In addition, sales to any
particular customer may fluctuate significantly from quarter to quarter, and such fluctuating sales could harm our business and financial results.

We
have significant international sales and operations and risks related to our international activities could harm our operating results.

In the nine months ended June 30, 2006, approximately 17% of our net sales was attributable to customers located in the U.S., 9% was attributable to customers located in Europe and 74% was attributable to customers located in Asia. In
fiscal 2005, approximately 15% of our net sales was attributable to customers in the U.S., 9% was attributable to customers in Europe and 75% was attributable to customers in Asia. We anticipate that sales to international sites will continue to
represent a significant percentage of our net sales. In addition, all of our wafer foundries and assembly and test subcontractors are in Taiwan, China and Singapore and a substantial majority of our employees are located outside of the U.S. In
particular, a devaluation of the New Taiwan dollar or Chinese Renminbi could substantially increase the cost of our operations in Taiwan or China.

We are subject to the risks of conducting business internationally, including:



| |  |  | global economic conditions, particularly in Taiwan and China;
| | - |  | -------------------------------------------------------------



| |  |  | duties, tariffs and other trade barriers and restrictions;
| | - |  | ----------------------------------------------------------



| |  |  | foreign currency fluctuations;

| |  |  | difficulties in hiring and retaining experienced engineers in countries such as China and Taiwan;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | difficulties in collecting foreign accounts receivable;
| | - |  | -------------------------------------------------------



| |  |  | political instability, including any changes in relations between China and Taiwan; and

Strong competition in the semiconductor memory market may harm our business.

The semiconductor memory market is intensely competitive and has been characterized by an oversupply of product, price erosion, rapid technological
change, short product life cycles, cyclical market patterns, and heightened foreign and domestic competition. Many of our competitors offer broader product lines and have greater financial, technical, marketing, distribution and other resources than
us. In particular, a competitor with a materially smaller die size and lower cost could dramatically gain market share in a short period of time. We may not be able to compete successfully against any of these competitors. Our ability to compete
successfully in the memory market depends on factors both within and outside of our control, including:



| |  |  | the pricing of our products;
| | - |  | ----------------------------



| |  |  | the supply and cost of wafers;
| | - |  | ------------------------------



| |  |  | product design, functionality, performance and reliability;
| | - |  | -----------------------------------------------------------



| |  |  | successful and timely product development;
| | - |  | ------------------------------------------



| |  |  | the performance of our competitors and their pricing policies;
| | - |  | --------------------------------------------------------------



| |  |  | wafer manufacturing over or under capacity;
| | - |  | -------------------------------------------



| |  |  | real or perceived imbalances in supply and demand for our products;
| | - |  | -------------------------------------------------------------------



| |  |  | the rate at which OEM customers incorporate our products into their systems;
| | - |  | ----------------------------------------------------------------------------



| |  |  | the success of our customers products and end-user demand;
| | - |  | -----------------------------------------------------------



| |  |  | access to advanced process technologies at competitive prices;
| | - |  | --------------------------------------------------------------



| |  |  | achievement of acceptable yields of functional die;
| | - |  | ---------------------------------------------------



| |  |  | the capacity of our third-party contractors to assemble and test our products;
| | - |  | ------------------------------------------------------------------------------



| |  |  | the gain or loss of significant customers;
| | - |  | ------------------------------------------



| |  |  | the nature of our competitors; and
| | - |  | ----------------------------------



| |  |  | general economic conditions.
| | - |  | ----------------------------

In
addition, we are vulnerable to technology advances utilized by competitors to manufacture higher performance or lower cost products. We may not be able to compete successfully in the future as to any of these factors. Our failure to compete
successfully in these or other areas could harm our business and financial results.

Our revenues and business would be harmed if we are not able to
successfully develop, introduce and sell new products and develop and implement new manufacturing technologies in a timely manner. Our research and development expenses could increase and our business could be harmed if the implementation of these
new manufacturing technologies is unsuccessful.

We operate in highly competitive, quickly changing markets which are characterized by
rapid obsolescence of existing products. As a result, our future success depends on our ability to develop and introduce new products that our customers choose to buy in significant quantities. If we fail to introduce new products in a timely manner
or if our customers products do not achieve commercial success, our business and results of operations could be seriously harmed. The design and introduction of new products is challenging as such products typically incorporate more functions
and operate at faster speeds than prior products. Increasing complexity generally requires smaller features on a chip. This makes developing new generations of products substantially more difficult than prior generations. The cost to develop
products utilizing these new technologies is expensive and requires significant research and development spending and, as a result, our research and

development expenses could increase in the future. Further, new products may not work properly in our customers applications. If we are unable to
design, introduce, market and sell new products successfully, our business and financial results would be seriously harmed.

Our products are complex
and could contain defects, which could reduce sales of those products or result in claims against us.

We develop complex and evolving
products. Despite testing by us and our customers, errors may be found in existing or new products. This could result in a delay in recognition or loss of revenues, loss of market share or failure to achieve market acceptance. The occurrence of
defects could also cause us to incur significant warranty, support and repair costs, could divert the attention of our engineering personnel from our product development efforts, and could harm our relationships with our customers. The occurrence of
these problems could result in the delay or loss of market acceptance of our products and would likely harm our business. Defects, integration issues or other performance problems in our products could result in financial or other damages to our
customers. Our customers could also seek and obtain damages from us for their losses. From time to time, we have been involved in disputes regarding product warranty issues. Although we seek to limit our liability, a product liability claim brought
against us, even if unsuccessful, would likely be time consuming and could be costly to defend.

Potential intellectual property claims and litigation
could subject us to significant liability for damages and could invalidate our proprietary rights.

In the semiconductor industry, it is
not unusual for companies to receive notices alleging infringement of patents or other intellectual property rights. We have been, and from time-to-time expect to be, notified of claims that we may be infringing patents, maskwork rights or
copyrights owned by third-parties. If it appears necessary or desirable, we may seek licenses under patents that we are alleged to be infringing. However, licenses may not be offered and the terms of any offered licenses may not be acceptable to us.

The failure to obtain a license under a key patent or intellectual property right from a third party for technology used by us could cause
us to incur substantial liabilities and to suspend the manufacture of the products utilizing the invention or to attempt to develop non-infringing products, any of which could harm our business. Furthermore, we may become involved in protracted
litigation regarding the alleged infringement by us of third-party intellectual property rights or litigation to assert and protect our patents or other intellectual property rights. Any litigation relating to patent infringement or other
intellectual property matters could result in substantial cost and diversion of our resources, which could harm our business.

We may be unable to
effectively protect our intellectual property, which would negatively impact our ability to compete.

We believe that the protection of
our intellectual proprietary rights will continue to be important to the success of our business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property
rights. We also enter into confidentiality or license agreements with our employees, consultants and business partners, and control access to and distribution of our documentation and other proprietary information. Despite these efforts,
unauthorized parties may attempt to copy or otherwise obtain and use our proprietary technology. Monitoring unauthorized use of our technology is difficult, and we cannot be certain that the steps we have taken will prevent unauthorized use of our
technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as do the laws of the U.S. Many U.S. companies have encountered substantial infringement problems in foreign countries, including countries
in which we design and sell our products. We cannot be certain that patents will be issued as a result of our pending applications nor can we be certain that any issued patents would protect or benefit us or give us adequate protection from
competing products. For example, issued patents may be circumvented or challenged and declared invalid or unenforceable. We also cannot be certain that others will not develop our unpatented proprietary technology or effective competing technologies
on their own.

We have acquired equity positions for strategic reasons in other companies which may significantly decrease in value.

Over the last several years, we have acquired equity positions for strategic reasons in other technology companies and we may make similar equity
purchases in the future. At June 30, 2006, our strategic investments in non-marketable securities totaled $3.5 million. These equity investments may not increase in value and there is the possibility that they could decrease in value over time,
even to the point of becoming completely worthless. These equity securities are evaluated for impairment on a recurring basis and any reductions in the carrying value would lower our profitability.

In this regard, we recorded approximately $0.3 million in impairment losses on two of our equity
positions in fiscal 2005. In addition, we own shares in SMIC with a cost basis of approximately $30.3 million and a market value at June 30, 2006 of approximately $37.5 million. The market value of SMIC shares is subject to fluctuation and our
carrying value will be subject to adjustments to reflect the current market value. Our shares in SMIC are subject to certain lockup restrictions and therefore all of such shares are not freely tradable. These lockup restrictions generally lapse at
the rate of 15% of our pre-offering shares every 180 days following SMICs IPO which occurred in March 2004. Thus, all of our shares in SMIC have been freely tradable only since February 2007. Through June 30, 2006, these lockup
restrictions impacted our ability to sell the locked up portion of our SMIC shares.

Changes in securities laws and regulations are increasing our
costs.

The Sarbanes-Oxley Act of 2002 that became law in July 2002, as well as new rules subsequently implemented by the Securities and
Exchange Commission and the Nasdaq Stock Market, have required changes to some of our accounting and corporate governance practices, including the report on our internal controls as required by Section 404 of the Sarbanes-Oxley Act of 2002.
These rules and regulations have increased our accounting, legal and other costs, and have made some activities more difficult, time consuming and/or costly. In particular, complying with the internal control requirements of Sarbanes-Oxley
Section 404 has resulted in increased internal efforts, significantly higher fees from our independent accounting firm and significantly higher fees from third party contractors. We also expect these rules and regulations to make it more
difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules and regulations could also make it more
difficult for us to attract and retain qualified executive officers and qualified members of our board of directors, particularly to serve on our audit committee.

We may experience difficulties and increased expenses in complying with Sarbanes-Oxley Section 404.

Pursuant to
Section 404 of the Sarbanes-Oxley Act of 2002, beginning with our Annual Report on Form 10-K for our fiscal year ending September 30, 2005, we are required to furnish a report by our management on our internal control over financial
reporting. Such report contains among other matters, an assessment of the effectiveness of our internal control over financial reporting as of the end of our fiscal year, including a statement as to whether or not our internal control over financial
reporting is effective. This assessment includes disclosure of any material weaknesses in our internal control over financial reporting identified by management and also contains a statement that our auditors have issued an attestation report on
managements assessment of such internal controls. Public Company Oversight Board Auditing Standard No. 2 provides the professional standards and related performance guidance for auditors to attest to, and report on, managements
assessment of the effectiveness of internal control over financial reporting under Section 404.

We concluded that our internal
control over financial reporting was effective and our auditors concurred with such assessment at September 30, 2005. Our internal control analysis for fiscal 2005 was not required to cover ICSI. However, ICSI will be covered by our internal
control analysis for fiscal 2006. A key element of Section 404 compliance involves an analysis of management information systems (MIS). We are in the process of implementing a new worldwide MIS system and we are continuing to use our current
systems. Although we are working to improve such system, there are some Section 404 challenges with the current systems at ICSI and there can be no assurance that such system issues will not result in a significant deficiency or material
weakness under applicable accounting standards. If in the future we are unable to assert that our internal control over financial reporting is effective (or if our auditors are unable to attest that our managements report is fairly stated or
they are unable to express an opinion on the effectiveness of our internal controls), we could lose investor confidence in the accuracy and completeness of our financial reports, which would have an adverse effect on our stock price.

Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the United States.

We prepare our financial statements in conformity with accounting principles generally accepted in the U.S. These accounting principles are subject to
interpretation by the Financial Accounting Standards Board, the American Institute of Certified Public Accountants, the Securities and Exchange Commission and various bodies formed to interpret and create appropriate accounting policies. A change in
these policies or interpretations could have a significant effect on our reported



56

##### Table of Contents

financial results, and could affect the reporting of transactions completed before the announcement of a change. For example, beginning in the first quarter
of fiscal 2006, with the adoption of SFAS 123R, we now record a charge to earnings for employee stock option grants for all stock options unvested at and granted after October 1, 2005. This accounting pronouncement has and is expected to
continue to negatively impact our financial results. Technology companies generally, and our company specifically, rely on stock options as a major component of our employee compensation packages. Because we are required to expense options, we may
be less likely to sustain profitability or we may have to decrease or eliminate option grants. Decreasing or eliminating option grants may negatively impact our ability to attract and retain qualified employees.

We depend on our ability to attract and retain our key technical and management personnel.

Our success depends upon the continued service of our key technical and management personnel. Several of our important manufacturing and other
subcontractor relationships are based on personal relationships between our senior executive officers and such parties. In particular, our Chairman and Chief Executive Officer has long-term relationships with our key foundries. If we were to lose
the services of any key executives, it may negatively impact the related business relationships since we have no long-term contractual agreements with such parties. Our success also depends on our ability to continue to attract, retain and motivate
qualified technical personnel, particularly experienced circuit designers and process engineers. The competition for such employees is intense. We have no employment contracts or key person life insurance policies with or for any of our employees.
The loss of the service of one or more of our key personnel could harm our business.

Our stock price is expected to continue to be volatile.

The trading price of our common stock has been and is expected to be subject to wide fluctuations in response to:



| |  |  | quarter-to-quarter variations in our operating results;
| | - |  | -------------------------------------------------------



| |  |  | general conditions or cyclicality in the semiconductor industry or the end markets that we serve;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | new or revised earnings estimates or guidance by us or industry analysts;
| | - |  | -------------------------------------------------------------------------



| |  |  | comments or recommendations issued by analysts who follow us, our competitors or the semiconductor industry;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | aggregate valuations and movement of stocks in the broader semiconductor industry;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | announcements of new products, strategic relationships or acquisitions by us or our competitors;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | increases or decreases in available wafer capacity;
| | - |  | ---------------------------------------------------



| |  |  | governmental regulations, trade laws and import duties;
| | - |  | -------------------------------------------------------



| |  |  | announcements related to future or existing litigation involving us or any of our competitors;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | announcements of technological innovations by us or our competitors;
| | - |  | --------------------------------------------------------------------



| |  |  | additions or departures of senior management; and
| | - |  | -------------------------------------------------



| |  |  | other events or factors, many of which are beyond our control.
| | - |  | --------------------------------------------------------------

In addition, stock markets have experienced extreme price and trading volume volatility in recent years. This volatility has had a substantial effect on the market prices of securities of many technology companies for
reasons frequently unrelated to the operating performance of the specific companies. These broad market fluctuations may adversely affect the market price of our common stock.

Foundry capacity can be limited, and we may be required to enter into costly arrangements to secure foundry capacity.

If we are not able to obtain additional foundry capacity as required, our relationships with our customers would be harmed and our
future sales would be adversely impacted. In order to secure foundry capacity, we have entered into in the past, and may enter into in the future, various arrangements with suppliers, which could include:



| |  |  | purchases of equity or debt securities in foundries;
| | - |  | ----------------------------------------------------



| |  |  | joint ventures;
| | - |  | ---------------



| |  |  | process development relationships with foundries;
| | - |  | -------------------------------------------------



| |  |  | contracts that commit us to purchase specified quantities of wafers over extended periods;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | increased price for wafers;
| | - |  | ---------------------------



| |  |  | option payments or other prepayments to foundries; and
| | - |  | ------------------------------------------------------



| |  |  | nonrefundable deposits with, or loans to, foundries in exchange for capacity commitments.
| | - |  | -----------------------------------------------------------------------------------------

We may not be able to make any such arrangements in a timely fashion or at all, and such arrangements, if any, may not be on terms favorable to us. Once
we make commitments to secure foundry capacity, we may incur significant financial penalties if we subsequently determine that we are not able to utilize all of that capacity. Such penalties may be substantial and could harm our financial results.

Our foundries may experience lower than expected yields which could adversely affect our business.

The manufacture of integrated circuits is a highly complex and technically demanding process. Production yields and device reliability can be affected by
a large number of factors. As is typical in the semiconductor industry, our outside foundries have from time to time experienced lower than anticipated manufacturing yields and device reliability problems, particularly in connection with the
introduction of new products and changes in such foundrys processing steps. There can be no assurance that our foundries will not experience lower than expected manufacturing yields or device reliability problems in the future, which could
materially and adversely affect our business and operating results.

Business disruptions could seriously harm our future revenue and financial
condition and increase our costs and expenses.

Our worldwide operations could be subject to natural disasters and other business
disruptions, which could seriously harm our revenue and financial condition and increase our costs and expenses. Our corporate headquarters, and a portion of our research and development activities, are located in California, and other critical
business operations and many of our suppliers are located in Asia, near major earthquake faults. The ultimate impact on us, our significant suppliers and our general infrastructure of being located near major earthquake faults is unknown, but our
revenue, profitability and financial condition could suffer in the event of a major earthquake or other natural disaster. Losses and interruptions could also be caused by earthquakes, power shortages, telecommunications failures, water shortages,
tsunamis, floods, typhoons, fires, extreme weather conditions, medical epidemics and other natural or manmade disasters.

Terrorist attacks, threats of
further attacks, acts of war and threats of war may negatively impact all aspects of our operations, revenues, costs and stock price.

Terrorist acts, conflicts or wars, as well as future events occurring in response or connection to them, including future terrorist attacks against U.S. targets, rumors or threats of war, actual conflicts involving the U.S. or its allies
(such as the war in Iraq), conflict between China and Taiwan, or trade disruptions impacting our domestic or foreign suppliers or our customers, may impact our operations and may, among other things, cause delays or losses in the delivery of wafers
or other products to us and decreased sales of our products. More generally, these events have affected, and are expected to continue to affect, the general economy and customer demand for products sold by our customers. Any of these occurrences
could have a significant impact on our operating results, revenues and costs, which in turn may result in increased volatility in our common stock price and a decline in the price of our common stock.
