NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The condensed consolidated financial statements include all the accounts of Applied Micro Circuits Corporation
(AppliedMicro, APM, AMCC or the Company), its wholly-owned subsidiaries and a variable interest entity (VIE) of which the Company is the primary beneficiary. A VIE is required to be
consolidated by its primary beneficiary. The primary beneficiary is the party that absorbs a majority of the VIEs anticipated losses and/or a majority of the expected returns. The Company has evaluated its strategic alliances for potential
classification as variable interest entities by evaluating the sufficiency of each entitys equity investment at risk to absorb losses and the Companys share of the respective expected losses. The Company determined that it is the primary
beneficiary of one VIE and has included the accounts of this entity in the condensed consolidated financial statements (see Note 10). All significant intercompany balances and transactions have been eliminated in consolidation.

In the opinion of management, the unaudited interim condensed consolidated financial statements of the Company included herein have been
prepared on a basis consistent with the March 31, 2010 audited consolidated financial statements and include all material adjustments, consisting of normal recurring adjustments, necessary to fairly present the information set forth therein.
These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Companys Annual Report on Form 10-K for the fiscal year
ended March 31, 2010. The Companys results of operations for the three and nine months ended December 31, 2010 are not necessarily indicative of future operating results.

As described in Note 9, the Company has classified the financial results of its 3ware storage adapter business as discontinued operations
for all periods presented due to the sale of its 3ware storage adapter business to LSI Corporation on April 21, 2009. These notes to the Companys condensed consolidated financial statements relate to continuing operations only, unless
otherwise indicated.

During the three months ended June 30, 2010, the Company made a correction resulting in the
recognition of an asset totaling $1.2 million for unamortized mask costs incurred in prior periods as it was determined that these costs represented pre-production costs instead of research and development (R&D) expenses. The
unamortized costs will be amortized as cost of sales over a period of approximately three years. As part of this correction, the Company recognized a reduction to R&D expenses of approximately $1.2 million. The net adjustments to make the
correction to capitalize mask costs were not material to any periods affected.

On September 17, 2010, the Company
completed the purchase of TPack A/S (TPack) for approximately $32 million in cash, exclusive of $0.5 million cash acquired, and potential additional contingent consideration of up to $5 million that will be payable upon the attainment of
certain milestones. For a complete discussion, see note 11, Acquisition of TPack A/S.

Use of Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net revenue and expenses in the reporting period. The Company regularly
evaluates estimates and assumptions related to its capitalized mask sets, which affects cost of goods sold and property and equipment or R&D expenses, if not capitalized; inventory valuation, warranty liabilities, and revenue reserves, which
affects revenues, cost of sales and gross margin; allowance for doubtful accounts, which affects operating expenses; the unrealized losses or other-than-temporary impairments of short-term investments available for sale, which affects interest
income (expense), net; the valuation of purchased intangibles and goodwill, which affects amortization and impairments of purchased intangibles and impairments of goodwill; the contingent consideration, which affects operating expenses; the
valuation of restructuring liabilities, which affects the amount and timing of restructuring charges; the potential costs of litigation, which affects operating expenses; the valuation of deferred income taxes, which affects income tax expense
(benefit); and stock-based compensation, which affects gross margin and operating expenses. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and
adversely from managements estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.

Recent Accounting Pronouncements

In April 2010, the FASB issued an amendment to ASC 605,Revenue Recognition, to provide guidance on defining a milestone and determining when it may be appropriate to apply the milestone method of
revenue recognition for research or development

transactions. This amendment to ASC 605 is effective on a prospective basis for milestones achieved in fiscal years, and interim periods within those years, beginning on or after June 15,
2010. Early adoption is permitted. This amendment is not expected to have a material impact for the Company.

Strategic Investments

The Company has entered into certain equity investments in privately held businesses for the promotion of business and strategic objectives. The Companys investments in equity securities of
privately held businesses are accounted for under the cost method. Under the cost method, strategic investments in which the Company holds less than a 20% voting interest and on which the Company does not have the ability to exercise significant
influence are carried at the lower of cost or cost reduced by other-than-temporary impairments, as appropriate. These investments are included in other assets on the Companys condensed consolidated balance sheets. The Company periodically
reviews these investments for other-than-temporary declines in fair value based on the specific identification method and writes down investments when an other-than-temporary decline has occurred.

The established guidelines for measuring fair value and expanded disclosures regarding fair value measurements
are defined as a three-level valuation hierarchy for disclosure of fair value measurements as follows:



|        |  |   |  |                                                                                                                                                                                                                                                                                                                                                                                                                                           
|------- |  | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1 |  |  |  | Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.                                                                                                                                                                                                                                                                                                                       
|        |  |  
|Level 2 |  |  |  | Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the
measurement date and for the duration of the instruments anticipated life.                                                                                                                                                                              
|        |  |  
|Level 3 |  |  |  | Inputs reflect managements best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk
inherent in the valuation technique and the risk inherent in the inputs to the model. Valuation of instruments includes unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or
liabilities.

There were no significant transfers in and out of Level 1 and Level 2 fair value
measurements during the three and mine months ended December 31, 2010.

The Company acquired certain intangible assets of
approximately $23.7 million in connection with a business combination during the three months ended September 30, 2010. The fair value of the intangible assets was estimated using Level 3 inputs. See Note 11 for discussion of this business
combination and the key inputs used in the valuation.

At December 31, 2010, the cost and estimated fair values of
available-for-sale securities with stated maturities are U.S. Treasury securities and agency bonds, corporate bonds and mortgage-backed and asset-backed securities and the contractual maturities of such securities are as follows (in thousands):

Other-Than-Temporary Impairment

The Company assessed whether it intends to sell or it is more likely than not that it will be required to sell an available-for-sale debt
instrument before recovery of its amortized cost basis less any current-period credit losses. For available-for-sale debt instruments that are considered other-than-temporarily impaired and that the Company does not intend to sell and will not be
required to sell prior to recovery of the amortized cost basis, the Company separates the amount of the impairment into the amount that is credit related and the amount due to all other factors. The credit loss component is recognized in earnings
and is the difference between the debt instruments amortized cost basis and the present value of its expected future cash flows. The remaining difference between the opening debt instruments fair value and the present value of future
expected cash flows is due to factors that are not credit related and is recognized in other comprehensive income (loss).

Based on an evaluation of securities that have been in a loss position, the Company did not recognize an other-than-temporary impairment
charge, for the three and nine months ended December 31, 2010. The Company considered various factors which included its intent and ability to hold the underlying securities until its estimated recovery of amortized cost. The
other-than-temporary impairment charge for the three and nine months ended December 31, 2009 was approximately $0.6 million and $4.0 million, respectively. As of December 31, 2010, the Company also has $9.1 million in gross unrealized
gains. The basis for computing realized gains or losses is by specific identification.

Warranty reserves:

The Companys products typically carry a one year warranty. The Company establishes reserves for estimated product warranty costs at the time revenue is recognized. Although the Company engages in
extensive product quality programs and processes, its warranty obligation is affected by product failure rates, use of materials and service delivery costs incurred in correcting any product failure. Should actual product failure rates, use of
materials or service delivery costs differ from the Companys estimates, additional warranty reserves could be required, which could reduce its gross margin.

The following table summarizes warranty reserve activity (in thousands):

Net income (loss) per share:

Shares used in basic net income (loss) per share are computed using the weighted average number of common shares outstanding during each
period. Shares used in diluted net income (loss) per share includes the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of restricted stock units (RSUs) and outstanding warrants. The
reconciliation of shares used to calculate basic and diluted net income (loss) per share consists of the following (in thousands, except per share data):

The effect of anti-dilutive securities (comprised of options and restricted stock units) totaling
4.1 million and 3.9 million equivalent shares for the three and nine months ended December 31, 2010, respectively, and 6.1 million and 6.8 million equivalent shares for the three and nine months ended December 31, 2009,
respectively, have been excluded from the net income (loss) per share computation.

The effect of dilutive securities
(comprised of options and restricted stock units) totaling 1.2 million equivalent shares for the three months ended December 31, 2010 and 2.0 million and 1.5 million equivalent shares for the three and nine months ended
December 31, 2009, respectively, have been excluded from the net loss per share computation, as their impact would be anti-dilutive because the company has incurred losses in the periods presented.

January 2010 Restructuring Program

The January 2010 restructuring program was implemented as part of the Companys ongoing cost reduction efforts and to better align
its global operations to achieve greater efficiencies. The Company moved some of its functions offshore, which will allow it to be much closer to its third party subcontract manufacturers, thus reducing costs by taking advantage of its global cost
structure and improving efficiencies by eliminating the delays inherent in working in different time zones. The January 2010 restructuring plan includes eliminating or relocating 63 positions. As a result of the January 2010 restructuring program,
the Company recorded a charge of $1.0 million, consisting of $0.6 million for employee severances and $0.4 million for an asset impairment in fiscal 2010. During the nine months ended December 31, 2010, the Company recorded an additional
charge of $0.5 million for employee severances. The Company expects to record additional charges of approximately $0.1 million for employee severances during the remainder of the fiscal year.

During the fiscal year ended March 31, 2010, approximately 0.4 million shares were issued under this plan. At December 31, 2010, approximately 4.2 million shares had been issued under this plan and approximately 2.1 million
shares were available for future issuance.

Stock Repurchase Program

In August 2004, the Board authorized a stock repurchase program for the repurchase of up to $200.0 million of the Companys common
stock. Under the program, the Company is authorized to make purchases in the open market or enter into structured stock repurchase agreements. In October 2008, the Board increased the stock repurchase program by $100.0 million. During the nine
months ended December 31, 2010, 2.1 million shares were repurchased on the open market at a weighted average price of $11.24 per share. During the fiscal year ended March 31, 2010, 1.1 million shares were repurchased on the open
market at a weighted average price of $7.54 per share. From the time the program was first implemented in August 2004, the Company has repurchased on the open market a total of 12.0 million shares at a weighted average price of $11.28 per
share. All repurchased shares were retired upon

delivery to the Company. In November 2010, the Company entered into a 10(b)-5 plan to repurchase up to 1.0 million shares of its common stock at various price parameters. The plan will
expire on May 31, 2011. As of December 31, 2010, the company repurchased approximately 20,000 shares at a weighted average price of $10.21 per share under this 10(b)-5 plan. In January 2011, the Board approved an additional
3.0 million shares to be repurchased under a 10(b)-5 plan.

The Company also utilizes structured stock repurchase
agreements to buy back shares which are prepaid written put options on its common stock. The Company pays a fixed sum of cash upon execution of each agreement in exchange for the right to receive either a pre-determined amount of cash or stock
depending on the closing market price of its common stock on the expiration date of the agreement. Upon expiration of each agreement, if the closing market price of its common stock is above the pre-determined price, the Company will have its cash
investment returned with a premium. If the closing market price is at or below the pre-determined price, the Company will receive the number of shares specified at the agreement inception. The Company considers the guidance in ASC Topic 480-10,
Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity and ASC Topic 815-40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Companys Own Stock.
Any cash received, including the premium, is treated as additional paid-in capital on the balance sheet.

During the nine
months ended December 31, 2010, the Company entered into structured stock repurchase agreements totaling $10.0 million. For those agreements that had been settled during the nine months ended December 31, 2010, the Company received $15.5
million in cash and 0.5 million in shares of its common stock at an effective purchase price of $10.01 per share from the settled structured stock repurchase agreements. During the fiscal year ended March 31, 2010, the Company entered into
structured repurchase agreements totaling $41.8 million. For those agreements that settled during the fiscal year ended March 31, 2010, the Company received $27.8 million in cash (including 0.7 million in gains) and 0.7 million in
shares of its common stock at an effective purchase price of $7.25 per share from the settled structured stock repurchase agreements. At December 31, 2010, the Company had no outstanding structured stock repurchase agreements. From the
inception of the Companys most recent stock repurchase program in August 2004, it entered into structured stock repurchase agreements totaling $267.5 million. Upon settlement of these agreements, as of December 31, 2010, the Company
received $179.8 million in cash and 9.0 million shares of its common stock at an effective purchase price of $9.79 per share.

Stock Options

The Company has granted stock options to employees
and non-employee directors under several plans. These option plans include two stockholder-approved plans (the 1992 Stock Option Plan and 1997 Directors Stock Option Plan) and four plans not approved by stockholders (the 2000 Equity Incentive
Plan, Cimaron Communications Corporations 1998 Stock Incentive Plan assumed in the fiscal 1999 merger, and JNI Corporations 1997 and 1999 Stock Option Plans assumed in the fiscal 2004 merger). Certain other outstanding options were
assumed through the Companys various acquisitions.

In March 2007, the Companys stockholders also approved the
amendment and restatement of the 1992 Stock Option Plan (i) to expand the type of awards available under the plan, (ii) to rename the plan as the 1992 Equity Incentive Plan, (iii) to extend the plans expiration date until
January 10, 2017, (iv) to increase the shares reserved under the plan by 2.3 million shares, (v) to serve as a successor plan to the 2000 Equity Incentive Plan, which is no longer used for equity awards, and (vi) to provide
that any shares subject to stock awards under the 2000 Equity Incentive Plan that terminate or are forfeited or repurchased (other than options issued under the 2000 Equity Incentive Plan that were tendered in the stock option exchange, which
occurred in May 2007) are added to the share reserve under the 1992 Equity Incentive Plan.

The Board has delegated administration of the Companys equity plans to the
Compensation Committee, which generally determines eligibility, vesting schedules and other terms for awards granted under the plans. Options under the plans expire not more than ten years from the date of grant and are generally exercisable upon
vesting. Vesting generally occurs over four years. New hire grants generally vest and become exercisable at the rate of 25% on the first anniversary of the date of grant and ratably on a monthly basis over a period of 36 months thereafter;
subsequent option grants to existing employees generally vest and become exercisable ratably on a monthly basis over a period of 48 months measured from the date of grant.

In May 2009, Dr. Gopi, our CEO, was awarded 300,000 stock options for Extraordinary Accomplishment. The Black-Scholes value of these stock options are $1.1 million. These options will
vest only if Company performance milestones are satisfied; otherwise they will expire unvested. The first milestone for 75,000 shares will vest only if we achieve an annual revenue target of $270 million or more for any fiscal year from fiscal 2010
through fiscal 2013. The next milestone for another 75,000 shares will vest only if we achieve an annual revenue target of $310 million or more for any fiscal year from fiscal 2010 through fiscal 2013 or an annual revenue target of $350 million or
more for fiscal 2014. The last milestone for 150,000 shares will vest only if we achieve an annual operating margin of 13.5% of annual revenue or higher in fiscal 2013 or 15% or higher for any fiscal year from fiscal 2010 through fiscal 2012. The
Company evaluates the probability of achieving the milestones and adjusts any stock option expense accordingly under stock-based compensation expense.

At December 31, 2010 and March 31, 2010, there were no shares of common stock subject to repurchase. Options are granted at prices at least equal to fair value of the Companys common stock
on the date of grant.

December 31, 2010 is set forth below:

At December 31, 2010, the weighted average remaining contractual term for options outstanding
is 4.1 years and for options vested is 3.3 years.

The aggregate pretax intrinsic value of options exercised during the nine
months ended December 31, 2010 was $1.5 million. This intrinsic value represents the excess of the fair market value of the Companys common stock on the date of exercise over the exercise price of such options.

The weighted average remaining contractual life and weighted average per share exercise price of options outstanding and of options
exercisable as of December 31, 2010 were as follows (in thousands, except exercise prices and years):

Restricted Stock Units

The Company has granted restricted stock units (RSUs) pursuant to its 2000 Equity Incentive Plan as part of its regular annual
employee equity compensation review program as well as to new hires. RSUs are share awards that, upon vesting, will deliver to the holder shares of the Companys common stock. Generally, RSUs vest ratably on a quarterly basis over four years
from the date of grant. For employees hired after May 15, 2006, RSUs will vest on a quarterly basis over four years from the date of hire provided that no shares will vest during the first year, at the end of which the shares that would have
vested during that year will vest and the remaining shares will vest over the remaining 12 quarters.

In May 2009, the Company
issued three-year RSU grants, or EBITDA Grants. Vesting for the EBITDA Grants is subject to (i) the Companys performance as measured by earnings before interest, taxes, depreciation and amortization (EBITDA), and
(ii) individual performance as measured by the accomplishment of goals and objectives. For the fiscal year ended March 31, 2010, approximately 34% of the three-year performance pool vested because the Companys performance exceeded
its stretch EBITDA target. For the fiscal year ending March 31, 2011, up to 42% of the remaining three-year performance pool can vest. Approximately 21% can vest for at plan Company performance, 28% can vest for
stretch Company performance and 42% can vest for extraordinary Company performance. The Company evaluates the probability of achieving the milestones and adjusts any RSU expense accordingly under stock-based compensation
expense.

RSU activity during the nine months ended December 31, 2010 is set forth below:

The weighted average remaining contractual term for the RSUs outstanding as of December 31, 2010 was
1.1 years.

Based on the closing price of the Companys common stock of $10.68 on December 31, 2010, the total
pretax intrinsic value of all outstanding RSUs on that date was $32.1 million.

The aggregate pretax intrinsic value of RSUs
released during the nine months ended December 31, 2010 was $15.1 million. This intrinsic value represents the fair market value of the Companys common stock on the date of release.

Warrants

On May 17, 2009, the Company entered into a merger and other agreements with Veloce Technologies, Inc. (Veloce) pursuant to which Veloce has agreed, among other things, to perform
development work for the Company on an exclusive basis for up to five years for cash and other consideration, including a warrant to purchase shares of the Companys common stock. The warrant vesting schedule was amended in conjunction with the
amended merger agreement on November 8, 2010.

The warrant expires on July 15, 2014 and has an exercise price of
$0.01 per share. The first vesting tranche was for 14% of the warrants and vested in November 2010. The second vesting tranche is also for 14% of the warrants and will vest in March 2011. The remaining shares will vest quarterly through December
2012. A portion of the vested shares have been committed to be distributed to the employees of Veloce and will be settled in cash instead of common stock. Veloce will sell the committed shares and distribute the proceeds to its employees. Therefore,
the Company has recognized stock-based compensation expense under R&D and recorded a corresponding liability for this distribution in the consolidated financial statements of the Company. No stock-based compensation expense has been recognized
for the portion of the warrants that have been retained by Veloce.

6. STOCK-BASED COMPENSATION

The Company estimates the fair value of stock-based compensation on the date of grant using an option-pricing model. The Company uses the
Black-Scholes option pricing model to estimate the fair value of its share-based payments, excluding RSUs, for which the Company uses the fair market value. The Black-Scholes model determines the fair value of share-based payment awards based on the
stock price on the date of grant and is affected by assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the Companys expected stock price volatility over the term of the
awards,

and actual and projected employee stock option exercise behaviors. Option-pricing models were developed for use in estimating the value of traded options that have no vesting or hedging
restrictions and are fully transferable. Although the fair value of stock options granted by the Company is estimated by the Black-Scholes model, the estimated fair value may not be indicative of the fair value observed in a willing buyer/willing
seller market transaction.

The fair value of the options granted during the three months ended December 31, 2010 and
2009 is estimated as of the grant date using the Black-Scholes option-pricing model assuming the weighted-average assumptions listed in the following table:

The weighted average
grant-date fair value per share of the restricted stock units awarded was $10.67 and $10.44 during the three and nine months ended December 31, 2010, respectively, compared to $7.98 and $6.67 during the three and nine months ended
December 31, 2009, respectively. The weighted average fair value per share was calculated based on the fair market value of the Companys common stock on the respective grant dates.

Effective April 1, 2010, the Company revised its estimated forfeiture rate used in determining the amount of stock-based
compensation from 5.8% to 6.6% as a result of an increasing rate of forfeitures in recent periods, which the Company believes is indicative of the rate it will experience during the remaining vesting period of currently outstanding unvested grants.

The amount of unearned stock-based compensation currently estimated to be expensed from now through fiscal
2015 related to unvested share-based payment awards at December 31, 2010 is $21.3 million. The weighted-average period over which the unearned stock-based compensation is expected to be recognized is approximately 2.1 years. If there are any
modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense. Future stock-based compensation expense and unearned
stock-based compensation will increase to the extent that the Company grants additional equity awards or assumes unvested equity awards in connection with acquisitions.

7. CONTINGENCIES

Legal Proceedings

The Company acquired JNI Corporation (JNI) in October 2003. In November 2001, a class action lawsuit was filed against JNI and the underwriters of its initial and secondary public offerings of
common stock in the U.S. District Court for the Southern District of New York, case no. 01 Civ 10740 (SAS). The complaint alleges that defendants violated the Securities Exchange Act of 1934, as amended (the Exchange Act), in connection
with JNIs public offerings. This lawsuit is among more than 300 class action lawsuits pending in this District Court that have come to be known as the IPO laddering cases. Pursuant to In re Initial Public Offering Securities
Litigation, No. 21 MC 92 (SAS), a settlement has been reached in all of the cases. On October 6, 2009, the Court issued an order granting final approval of the settlement and dismissing the case. The Court subsequently issued a
final judgment. Several appeals of the settlement and judgment were filed between October 29 and November 4, 2009. Should the settlement be overturned on appeal and the final approval vacated, the Companys liability, if
any, could not be reasonably estimated at this time.

In 1993, the Company was named as a Potentially Responsible Party
(PRP) along with more than 100 other companies that used an Omega Chemical Corporation waste treatment facility in Whittier, California. The Company is a member of a large group of PRPs, known as the Omega Chemical Site PRP Organized
Group (OPOG) that has agreed to fund certain on-going remediation efforts at the Omega site. The U.S. Environmental Protection Agency (EPA) has alleged that Omega failed to properly treat and dispose of certain hazardous
waste materials. On February 26, 2001 the U.S. District Court for the Central District of California approved a consent decree between the EPA and OPOG to study contamination and evaluate cleanup options at the Omega site. Under the terms of
the consent decree, EPA agreed to supervise OPOGs soil remedial investigation and feasibility study, groundwater treatment design and the installation of three groundwater monitoring wells downgradient from the Omega site. On January 22,
2009, the District Court ordered that the first and second amendments to the consent decree be entered and made part of the consent decree. The First Amendment expanded the scope of work to mitigate volatile organic compounds affecting indoor air
quality at a roller rink neighboring the Omega site and, the Second Amendment added settling parties to the consent decree. On November 7, 2007, Angeles Chemical Company filed Angeles Chemical Company, Inc. et al. v. Omega Chemical PRP Group,
LLC, et al., in the U.S. District Court for the Central District of California against OPOG for cost recovery and indemnification for future response costs resulting from an alleged regional groundwater contamination plume originating at the Omega
site. On March 27, 2008, the Court granted OPOGs motion to stay the action pending EPAs determination of how to investigate and remediate the regional groundwater. Proceedings are ongoing and at this time, the Company does not
believe that any eventual outcome will have a material adverse effect on its operations.

Tpack, the Companys wholly
owned subsidiary acquired in September 2010, is involved in a contractual dispute with Xtera Communications Inc. and its subsidiary Meriton Networks, Canada Inc. (collectively, Xtera). In August 2009, Xtera filed an action against Tpack
in the United States District Court for the Eastern Division of Texas. In October 2010, the action was dismissed for lack of jurisdiction. A related lawsuit was brought by Tpack against Xtera in September 2009 in the Ontario Superior Court of
Justice in Canada, which suit is still pending. Further actions may be initiated by Tpack or Xtera with respect to the subject matter of the foregoing cases. The Company does not currently anticipate that the Tpack/Xtera legal proceedings will have
a material adverse effect on Tpack, the Company or their respective operations.

On or about November 10, 2010, a
complaint was filed in the United States Bankruptcy Court for the District of Delaware by Nortel Networks, Inc., (Nortel) against AMCC Sales Corporation (AMCC Sales), one of our wholly owned subsidiaries. The Complaint
alleges that in the 90 days prior to Nortels bankruptcy filing, which occurred on January 14, 2009, AMCC Sales received approximately $548,000 of payments that were preferential and that the transfer of such funds is subject to avoidance
and recovery by Nortel pursuant to Sections 547, 550, 551 and/or 502(d) of Title 11 of the United States Code. AMCC Sales has not yet responded to the Complaint.

8. INCOME TAXES

The total amount of unrecognized tax benefits as of
April 1, 2010, was $38.8 million, including interest and penalties. During the quarter ended December 31, 2010, additional unrecognized tax benefits of $28,000 were recorded. The Company does not foresee significant changes to its
estimated amount of liability associated with its uncertain tax positions within the next twelve months.

The Companys
income tax expense consists of state taxes and foreign taxes. The federal statutory income tax rate was 35% for the three months ended December 31, 2010 and 2009. The Companys income tax expense for the three and nine months ended
December 31, 2010 was a $0.2 million benefit and a $0.4 million expense, respectively, as compared to an income tax benefit of $2.2 million and $9.4 million during the three and nine months ended December 31, 2009, respectively. The
increase in the income tax expense recorded for the three and nine months ended December 31, 2010 compared to the three and nine months ended December 31, 2009, was primarily related to the income tax benefit arising from the tax expense
recognized in connection with the income from discontinued operations and unrealized gains included in other comprehensive income being allocated to continuing operations for the three and nine months ended December 31, 2009.

##### Table of Contents

The Company is subject to taxation in the U.S. and various state and foreign jurisdictions.
The Company is currently under audit by the North Carolina Department of Revenue for fiscal years 2006 to 2008. Effectively, all of the Companys historical tax years are subject to examination by the Internal Revenue Service and various state
jurisdictions due to the generation of net operating loss and credit carryforwards. With few exceptions, the Company is no longer subject to foreign examinations by tax authorities for years before 2007.

9. SALE OF THE 3WARE STORAGE ADAPTER BUSINESS TO LSI CORPORATION

On April 5, 2009, the Company entered into a Purchase Agreement with LSI Corporation (LSI). Under the Purchase Agreement, the Company agreed to sell to LSI substantially all of the
operating assets (other than patents) primarily used or held for use in its 3ware storage adapter business (the Storage Business) but retaining certain assets, including patents, cash, accounts receivable and accounts payable, even if
related to the Storage Business (the Transaction). The assets sold included customer contracts, inventory, fixed assets, certain intellectual property and other assets, as well as rights to the name 3ware.

The Company completed the Transaction on April 21, 2009. After adjustments for the level of inventory of $0.7 million and products
in the channel of $0.8 million, the final adjusted price of the Transaction was approximately $21.5 million for a gain of $11.4 million. During the fiscal year ended March 31, 2010, the Company and LSI reached an agreement to end the warranty
support portion of the Purchase Agreement. As a result of the Transaction, the Company decreased its number of full-time employees by 56.

The Company has reclassified the financial results of the 3ware storage adapter business as discontinued operations for all periods presented.

10. VELOCE

On November 8, 2010, the Company and Veloce amended
certain agreements, initially entered into on May 17, 2009, pursuant to which Veloce has agreed to perform product development work for the Company on an exclusive basis for up to five years for cash and other consideration, including a warrant
to purchase shares of the Companys common stock, which will vest in quarterly increments through December 2012. The warrant was 14% vested as of December 31, 2010. A portion of the vested shares have been committed to be distributed to
the employees of Veloce and will be settled in cash instead of common stock. Therefore, the Company has recognized stock-based compensation expense in R&D expense and recorded a corresponding liability for this distribution in the consolidated
financial statements of the Company. In addition, Veloce has granted stock options pursuant to its own stock incentive plan. Stock-based compensation expense recognized in connection with this plan was not material and is included in R&D
expense.

The Company has determined that Veloce, a California corporation, is a VIE by evaluating the sufficiency of the
entitys equity investment at risk to absorb losses and the Companys share of respective expected losses and determined that the Company is the primary beneficiary of the VIE. The Company has included the accounts of Veloce in the
consolidated financial statements and all significant intercompany balances and transactions have been eliminated in consolidation.

Under the amended merger agreement between the Company and Veloce, which has been approved by Veloces Board of Directors and stockholders, the Company also agreed to acquire Veloce if certain
performance milestones and delivery schedules set forth under the merger and other agreements are achieved. The Company also has the unilateral option to acquire Veloce in the event Veloce fails to meet the milestones and delivery schedules. Should
the Company acquire Veloce pursuant to the merger agreement, the purchase price payable by the Company is estimated to be in the range of approximately $7 million up to approximately $135 million, subject to additional adjustments. The final price
would be based upon the achievement and timing of multiple development and performance milestones and currently is not determinable. The form of consideration used for the merger, cash or the Companys stock, would be determined by the Company
at the time of the merger. The merger agreement contains customary representations, warranties and covenants and may be terminated upon mutual agreement of the parties or unilaterally by the Company or Veloce if the other party fails to meet certain
conditions set forth in the agreement. The amended agreements permit the Company to appoint two individuals to serve on Veloces Board of Directors and Board committees. The Companys chief executive officer and another member of the
Companys Board of Directors have been appointed to Veloces Board of Directors. As of December 31, 2010, the performance milestones and delivery schedules set forth under the merger and other agreements have not been achieved.

In addition, the Company has provided Veloce a promissory note of $1.5 million to be forgiven over eight quarters starting on
March 31, 2011. If Veloce commits a material breach of the merger agreement, the outstanding principal amount of the note and accrued interest is due to the Company. If the Company commits a material breach of the merger agreement, the
outstanding principal amount of the note and accrued interest is to be forgiven by the Company. The $1.5 million promissory note is eliminated in consolidation. Pursuant to the product development agreement, as amended, the Company will pay Veloce
$2.3 million per quarter for up to twelve consecutive quarters in order to assist Veloce in meeting its expenses to perform its obligations under the agreement and the Company will recognize the payments as research and development expenses when
such operating costs have been incurred by Veloce. The Company recognized $3.3 million and $7.7 million as research and development expense during the three and nine months ended December 31, 2010, respectively, compared to $2.3 million and
$4.3 million during the three and nine months ended December 31, 2009, respectively. The Company also will pay certain product development and manufacturing expenses if and when incurred by Veloce.

11. ACQUISITION OF TPACK A/S.

On September 17, 2010, the Company acquired all of the shares of TPack, a Danish Corporation organized under the laws of Denmark. The
Company believes the acquisition of TPack, a provider of silicon intellectual property for Mapping and Switching functions to leading telecom and networking equipment suppliers, will enable AppliedMicro to expand its presence and customer
relationships in the rapidly growing OTN and Carrier Ethernet markets.

The total consideration paid at the closing of the
transaction (the Closing) was approximately $32 million, exclusive of $0.5 million cash acquired. Following certain working capital adjustments, deductions for transaction expenses, including without limitation, those related to certain
change in control bonuses owed by the former shareholders of TPack to TPacks employees, and indemnity escrow holdbacks of approximately $5 million, a balance of approximately $22.6 million was paid at the Closing to the former shareholders of
TPack. The former TPack shareholders may also earn up to approximately $5 million in additional consideration, subject to the achievement of certain revenue and performance milestones by TPack during the 18 month period following the Closing. The
Company recorded the initial fair value of the contingent consideration liability which was calculated based on a weighted probability assessment. The liability will continue to be measured at fair value at the end of each reporting period. In
addition, we recorded acquisition related transaction costs of $0.9 million, which were included in selling, general and administrative expenses.

The Company has calculated the fair value of the tangible and intangible assets acquired to allocate the purchase price as of the acquisition date. The excess of purchase price over the aggregate fair
values was recognized as goodwill. Based upon these calculations, the preliminary purchase price of the transaction was allocated as follows (in thousands), and also includes the estimated amortization period of the acquired intangibles:

|* | The amount resulted primarily from our expectation of synergies from the integration of TPack product offerings with our product offerings
|- | ------------------------------------------------------------------------------------------------------------------------------------------

The fair values of the TPack intangible assets were determined using the income approach with significant inputs that are not observable
in the market. Key assumptions included expected future cash flows and discount rates consistent with the assessment of risk. Purchased intangible assets, including IPR&D, are amortized using a method that reflects the pattern in which the
economic benefits of the intangible assets are consumed or otherwise used, or if that pattern cannot be reliably determined, using a straight-line amortization method.

In January 2011, TPacks supplier of Field Programmable Gate Arrays (FPGAs) announced they acquired a competitor of TPack. This supplier will continue to provide FPGAs for TPacks
current products but not for any future products. The Company is currently negotiating with another supplier of FPGAs. The process of changing FPGA suppliers could adversely affect the future revenue streams used to value the purchased intangible
assets and contingent consideration of TPack. In which case, the Company may recognize an impairment of the purchased intangible assets and/or a decrease in the contingent consideration.

OVERVIEW

Applied Micro Circuits Corporation (AppliedMicro, APM, AMCC, the Company, we or our) is a leader in semiconductor solutions for the
enterprise, telecom and consumer/small medium business (SMB) markets. We design, develop, market, sell and support high-performance low power ICs, which are essential for the processing, transporting and storing of information worldwide.
In the telecom and enterprise markets, we utilize a combination of design expertise coupled with system-level knowledge and multiple technologies to offer IC products for wireline and wireless communications equipment such as wireless access points,
wireless base stations, multi-function printers, enterprise and edge switches, blade servers, storage systems, gateways, core switches, routers, metro, long-haul, and ultra-long-haul transport platforms. In the consumer/SMB markets, we combine
optimized software and system-level expertise with highly integrated semiconductors to deliver comprehensive reference designs and stand-alone semiconductor solutions for wireline and wireless communications equipment such as wireless access points,
network attached storage, and residential and smart energy gateways. Our corporate headquarters are located in Sunnyvale, California. Sales and engineering offices are located throughout the world.

Our business had three reporting units, Process, Transport and Store. On April 21, 2009, we completed the sale of our 3ware storage
adapter business, which was substantially all of the business of our Store reporting unit, to LSI Corporation to focus on our Process and Transport reporting units. We are a semiconductor company that possesses fundamental and differentiated
intellectual property for high speed signal processing, packet based communications processors and telecommunications transport protocols. This intellectual property enables us to be a key player in the datacenter, enterprise and telecommunications
applications. Our customer focus is on the OEMs and telecommunications companies that build and connect to datacenters. As of December 31, 2010, our business had two reporting units, Process and Transport.

On September 17, 2010, we completed the acquisition of TPack, a limited liability company organized under the laws of Denmark, in
accordance with the terms and conditions of the stock purchase agreement dated August 17, 2010. The revenues of TPack have been included in our Transport reporting unit.

##### Table of Contents

Since the start of fiscal 2009, we have invested a total of $254.6 million in the research
and development of new products, including higher-speed, lower-power and lower-cost products, products that combine the functions of multiple existing products into single highly integrated products, and other products to complete our portfolio of
communications products. These products, and our customers products for which they are intended, are highly complex. Due to this complexity, it often takes several years to complete the development and qualification of these products before
they enter into volume production. Accordingly, we have not yet generated significant revenues from some of the products developed during this time period. In addition, downturns in the telecommunications market can severely impact our
customers business and usually results in significantly less demand for our products than was expected when the development work commenced.

The following tables present a summary of our results of operations for the three and nine months ended December 31, 2010 and 2009 (dollars in thousands):

Net Revenues. We generate revenues primarily through sales of our IC products, embedded
processors and printed circuit board assemblies to OEMs, such as Alcatel-Lucent, Ciena, Cisco, Brocade, Fujitsu, Hitachi, Huawei, Juniper, Ericsson, NEC, Nortel, Nokia Siemens Networks, and Tellabs, who in turn supply their equipment principally to
communications service providers.

In July 2008, we entered into a Patent Purchase Agreement (the Agreement) with
QUALCOMM Incorporated (Qualcomm). Pursuant to the Agreement, we agreed to sell a series of our patents, patent applications and associated rights related to certain technologies for an aggregate purchase price of $33.0 million. The
purchase price is being paid over three years in equal quarterly payments of $3.0 million each beginning in the three months ended December 31, 2008 through March 31, 2011. Due to the nature of the payment terms, related revenue is being
recorded as the payments are received.

In November 2009, we also entered into another Patent Purchase Agreement with Acacia Patent
Acquisition LLC (APAC). Pursuant to this Agreement, we agreed to sell a series of our patents, patent applications and associated rights related to certain technologies for an aggregate purchase price of $2.5 million payable over two
years and a 25% share of royalty payments for assignment of rights under the sale and or use of the patents. Due to the nature of the payment terms, related revenue is being recorded as the payments are received.

The demand for our products has been affected in the past, and may continue to be affected in the future, by various factors, including,
but not limited to, the following:



| |  |  | the timing, rescheduling or cancellation of significant customer orders and our ability, as well as the ability of our customers, to manage inventory
corrections;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the qualification, availability and pricing of competing products and technologies and the resulting effects on sales and pricing of our products.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to specify, develop or acquire, complete, introduce, and market new products and technologies in a cost effective and timely manner;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the rate at which our present and future customers and end-users adopt our products and technologies in our target markets;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | general economic and market conditions in the semiconductor industry and communications markets;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | combinations of companies in our customer base, resulting in the combined company choosing our competitors IC standardization other than our
supported product platforms;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the gain or loss of one or more key customers, or their key customers, or significant changes in the financial condition of one or more of our key
customers or their key customers; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to meet customer demand due to capacity constraints at our suppliers.
| | - |  | ---------------------------------------------------------------------------------

For these and other reasons, our net revenue and results of operations for the three and nine months ended December 31, 2010 and
2009 may not necessarily be indicative of future net revenue and results of operations.

Based on direct shipments, net
revenues to customers that were equal to or greater than 10% of total net revenues were as follows:

We expect that our largest
customers will continue to account for a substantial portion of our net revenue for the foreseeable future.

All of our revenues are primarily denominated in U.S. dollars.

Sale of the 3ware storage adapter business to LSI Corporation.We completed the sale of our 3ware storage adapter business (the
Transaction) to LSI Corporation on April 21, 2009. Under the Asset Purchase Agreement with LSI Corporation (the Purchase Agreement), we sold substantially all of the operating assets (other than patents) of our 3ware
storage adapter business. The adjusted purchase price was approximately $21.5 million. Unless otherwise specified, all amounts discussed in the Managements discussion and analysis addresses only continuing operations.

Key non-GAAP measurements.We use certain non-GAAP metrics such as Adjusted Earnings
Before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA) to measure our performance. We define Adjusted EBITDA as net income (loss) less interest income, income taxes, depreciation and amortization, stock-based
compensation, amortization of intangibles and other one-time and/or non-cash items. The following table reconciles Adjusted EBITDA to the accompanying financial statements:

We believe that Adjusted EBITDA is a useful supplemental measure of our operations performance because it helps investors
evaluate and compare the results of operations from period to period by removing the accounting impact of the companys financing strategies, tax provisions, depreciation and amortization, restructuring charges, stock based compensation
expense, discontinued operations and other operating items that are outside the Companys ordinary course of business. We adjust for these excluded items because we believe that, in general, these items possess one or more of the following
characteristics: their magnitude and timing is largely outside of the companys control; they are unrelated to the ongoing operation of the business in the ordinary course; they are unusual or infrequent and the company does not expect them to
occur in the ordinary course of business; or they are non-operational or non-cash expenses.

Adjusted EBITDA is not a measure
determined in accordance with generally accepted accounting principles in the United States, or GAAP, and should not be considered a substitute for operating income, net income or any other measure determined in accordance with GAAP. Adjusted EBITDA
should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Adjusted EBITDA is used by our management as a measure of operating efficiency and overall financial performance for benchmarking
against our peers and competitors and is used as a metric to determine the performance vesting of our three-year restricted stock unit grants issued in May 2009 (the EBITDA Grants) in the fiscal year ended March 31, 2010 and fiscal
years ending March 31, 2011 and 2012. Management believes Adjusted EBITDA provides meaningful supplemental information regarding the underlying operating performance of our business. Management also believes that Adjusted EBITDA is useful to
investors because it is frequently used by securities analysts, investors and other interested parties to evaluate the company.

The book-to-bill ratio is another metric commonly used by investors to compare and evaluate technology and semiconductor companies. The
book-to-bill ratio is a demand-to-supply ratio that compares the total amount of orders received to the total amount of orders filled. This ratio tells whether the company has more orders than it delivered (if greater than 1), has the same amount of
orders that it delivered (equals 1), or has less orders than it delivered (under 1). Though the ratio provides an indicator of whether orders are rising or falling, it does not consider the timing of, or if the order will result in future revenues.
Our book-to-bill ratio at December 31, 2010 and 2009 was 0.9 and 1.0, respectively.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements in accordance with accounting principles generally accepted in the United
States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of net revenue and expenses in the reporting period. We regularly
evaluate our estimates and assumptions related to: inventory valuation and capitalized mask set costs, which affect our cost of sales and gross margin; the valuation of goodwill and purchased intangibles, which has in the past affected, and could in
the future affect, our impairment charges

to write down the carrying value of purchased intangibles and the amount of related periodic amortization expense recorded for definite-lived intangibles; the valuation of restructuring
liabilities, which affects the amount and timing of restructuring charges; and an evaluation of other-than-temporary impairment of our investments, which affects the amount and timing of write-down charges. We also have other key accounting
policies, such as our policies for stock-based compensation and revenue recognition, including the deferral of a portion of revenues on sales to distributors. The methods, estimates and judgments we use in applying these critical accounting policies
have a significant impact on the results we report in our financial statements. We base our estimates and assumptions on historical experience and on various other factors that we believe to be reasonable under the circumstances, the results of
which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results experienced by us may differ materially and adversely from managements
estimates. To the extent there are material differences between our estimates and the actual results, our future results of operations will be affected.

We believe the following critical accounting policies require us to make significant judgments and estimates in the preparation of our consolidated financial statements.

Inventory Valuation

Our policy is to value inventories at the lower of cost or market on a part-by-part basis. This policy requires us to make estimates regarding the market value of our inventories, including an assessment
of excess or obsolete inventories. We determine excess and obsolete inventories based on an estimate of the future demand for our products within a specified time horizon, generally 12 months. The estimates we use for future demand are also used for
near-term capacity planning and inventory purchasing and are consistent with our revenue forecasts. If our demand forecast is greater than our actual demand we may be required to take additional excess inventory charges, which would decrease gross
margin and net operating results. For example, as of December 31, 2010, reducing our future demand estimate to six months could decrease our current inventory valuation by approximately $1.4 million or increasing our future demand forecast to
18 months could increase our current inventory valuation by approximately $0.3 million.

Goodwill, Purchased Intangible
Assets and Other Long-Lived Assets

The purchase method of accounting for acquisitions requires extensive use of accounting
estimates and judgments to allocate the purchase price to the fair value of the net tangible and intangible assets acquired, such as purchased technology. Goodwill and purchased intangible assets deemed to have indefinite lives are not amortized,
but are subject to annual impairment tests. The values and useful lives assigned to other intangible assets impact future amortization. Determining the fair values and useful lives of intangible assets requires the use of estimates and the exercise
of judgment on factors such as expectations for the success and life cycle of products and technology acquired. While there are a number of different generally accepted valuation methods to estimate the value of intangible assets acquired, we
primarily use the discounted cash flow method and the market comparison approach. These methods require significant management judgment to forecast the future operating results used in the analysis. In addition, other significant estimates are
required such as residual growth rates and discount factors. The estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical
information and industry estimates and averages. These judgments can significantly affect our net operating results.

In
accordance with ASC Topic 350-10 (ASC 350-10) as it relates to Goodwill and Other Intangible Assets, the Company performs its annual impairment review at the reporting unit level each fiscal year or more frequently if the Company
believes indicators of impairment are present. ASC 350-10 requires that goodwill and certain intangible assets be assessed for impairment using fair value measurement techniques. Specifically, goodwill impairment is determined using a two-step
process. The first step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount, including goodwill. Goodwill is allocated to reporting units based upon the
type of products under development by the acquired company, which initially generated the goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired and the second step of
the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss. The second step of the goodwill impairment
test compares the implied fair value of the reporting units goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting units goodwill exceeds the implied fair value of that goodwill, an impairment loss is
recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of
the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit was the purchase price paid to acquire the reporting
unit. The fair value is determined using a combination of the discounted cash flow analysis and/or market comparisons. The determination of fair value requires significant judgment and estimates. The Company last recorded goodwill impairment charges
in the year ended March 31, 2009 of $223.0 million to continuing operations and $41.2 million to discontinued operations. In conjunction with the TPack acquisition, we recorded $23.7 million in amortizable intangible assets and $13.8 million in
goodwill. We evaluate the useful lives of our intangible assets each reporting period to determine whether events and circumstances require revising the remaining period of amortization.

##### Table of Contents

We evaluate our long-lived assets such as property, plant and equipment and purchased
intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the carrying value of an asset or asset group may not be recoverable. The carrying value of an asset or asset group is not recoverable if the
amount of undiscounted future cash flows the assets are expected to generate (including any net proceeds expected from the disposal of the asset) are less than its carrying value. When we identify an impairment has occurred, we reduce the carrying
value of the assets to its comparable market value (if available and appropriate) or to its estimated fair value based on a discounted cash flow approach.

Investments

We hold a variety of securities that have varied underlying
investments. We review our investment portfolio periodically to assess for other-than-temporary impairment. We assess the existence of impairment of our investments in order to determine the classification of the impairment as temporary
or other-than-temporary. The factors used to determine whether an impairment is temporary or other-than-temporary involve considerable judgment. The recent economic climate and volatile financial markets have created an environment in
which it may be difficult to make accurate estimates and assumptions on which we base our judgments. The factors we consider in determining whether any individual impairment is temporary or other-than-temporary are primarily the length of the time
and the extent to which the market value has been less than amortized cost, the nature of underlying assets (including the degree of collateralization), the financial condition, credit rating, market liquidity conditions and near-term prospects of
the issuer. If the fair value of a debt security is less than its amortized cost basis at the balance sheet date, an assessment would have to be made as to whether the impairment is other-than-temporary. If we decided to sell the security, an
other-than-temporary impairment shall be considered to have occurred. However, if we do not intend to sell the debt security, we shall consider available evidence to assess whether it more likely than not will be required to sell the security before
the recovery of its amortized cost basis due to cash, working capital requirements, contractual or regulatory obligations indicate that the security will be required to be sold before a forecasted recovery occurs. If it is more likely than not that
we are required to sell the security before recovery of its amortized cost basis, an other-than-temporary impairment is considered to have occurred. If we do not expect to recover the entire amortized cost basis of the security, we would not be able
to assert that we will recover its amortized cost basis even if we do not intend to sell the security. Therefore, in those situations, an other-than-temporary impairment shall be considered to have occurred. Use of present value cash flow models to
determine whether the entire amortized cost basis of the security will be recovered is expected. We will compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. An
other-than-temporary impairment is said to have occurred if the present value of cash flows expected to be collected is less than the amortized cost basis of the security. In the three and nine months ended December 31, 2010, we did not record
any other-than-temporary impairment charges. For the three months ended December 31, 2010, we did not record an impairment charge in connection with other securities in a continuous loss position (fair value less than carrying value) with
unrealized losses of $1.3 million as we believe that such unrealized losses are temporary. As of December 31, 2010, we also had $9.1 million in unrealized gains. For the three and nine months ended December 31, 2009, we recorded
other-than-temporary impairment charges of $0.6 million and $4.0 million, respectively.

Mask Costs

We incur significant costs for the fabrication of masks used by our contract manufacturers to manufacture our products. If we determine,
at the time the cost for the fabrication of masks are incurred, that technological feasibility of the product has been achieved, we consider the nature of these costs to be pre-production costs. Accordingly, such costs are capitalized as property
and equipment under machinery and equipment and are amortized as cost of sales over approximately three years, representing the estimated production period of the product. If we determine, at the time fabrication mask costs are incurred, that either
technological feasibility of the product has not occurred or that the mask is not reasonably expected to be used in production manufacturing or that the commercial feasibility of the product is uncertain, the related mask costs are expensed to
R&D in the period in which the costs are incurred. We will also periodically assess capitalized mask costs for impairment. During the three months ended December 31, 2010, total mask costs of $3.2 million were incurred, of which $1.5
million was expensed as R&D expense because technological feasibility had not been achieved and the remaining $1.7 million was capitalized. During the nine months ended December 31, 2010, total mask costs of $9.3 million were incurred, of
which $4.6 million was expensed as R&D expense and the remaining $4.7 million was capitalized.

During the three months
ended June 30, 2010, we made a correction resulting in the recognition of an asset totaling $1.2 million for unamortized mask costs incurred in prior periods as it was determined that these costs represented pre-production costs instead of
R&D expenses. The unamortized costs will be amortized as cost of sales over a period of approximately three years. As part of this correction we recognized a reduction to R&D expenses of approximately $1.2 million. Amortization of these
capitalized mask set costs recognized as cost of sales during the three and nine months ended December 31, 2010 was approximately $0.1 million and $0.4 million, respectively. The net adjustments to make the correction to capitalize mask costs
were not material to any periods affected.

Restructuring Charges

Over the last several years we have undertaken significant restructuring initiatives, which have required us to develop formalized plans
for exiting certain business activities and reducing spending levels. We have had to record estimated expenses for employee severance, long-term asset write downs, lease cancellations, facilities consolidation costs, and other restructuring costs.
Given the significance, and the timing of the execution, of such activities, this process is complex and involves periodic reassessments of estimates made at the time the original decisions were made. Our assumptions for exiting certain facilities,
such as estimating sublease incomes, may differ from actual outcomes, which could result in the need to record additional costs or reduce estimated amounts previously charged to restructuring expense. Our policies require us to periodically evaluate
the adequacy of the remaining liabilities under our restructuring initiatives. For the nine months ended December 31, 2010, we recorded net restructuring charges of approximately $0.6 million associated with our restructuring actions. In the
fiscal year ended March 31, 2010, we recorded net charges of $0.8 million for our restructuring activities to continuing operations.

Stock-Based Compensation Expense

All share-based payments, including
grants of stock options, restricted stock units and employee stock purchase rights, are required to be recognized in our financial statements based on their respective grant date fair values. The fair value of each employee stock option and employee
stock purchase right is estimated on the date of grant using an option pricing model that meets certain requirements. We currently use the Black-Scholes option pricing model to estimate the fair value of our share-based payments, excluding RSUs,
which we use the fair market value of our common stock. The fair values generated by the Black-Scholes model may not be indicative of the actual fair values of our stock-based awards as it does not consider certain factors important to stock-based
awards, such as continued employment, periodic vesting requirements and limited transferability. The determination of the fair value of share-based payment awards utilizing the Black-Scholes model is affected by our stock price and a number of
assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. We estimate the expected volatility of our stock options at grant date by equally weighting the historical volatility and the implied
volatility of our stock over specific periods of time as the expected volatility assumption required in the Black-Scholes model. The expected life of the stock options is based on historical and other data including life of the option and vesting
period. The risk-free interest rate assumption is the implied yield currently available on zero-coupon government issues with a remaining term equal to the expected term. The dividend yield assumption is based on our history and expectation of
dividend payouts. The fair value of our restricted stock units is based on the fair market value of our common stock on the date of grant. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods
if actual forfeitures differ significantly from those estimated. We evaluate the assumptions used to value stock-based awards on a quarterly basis. If factors change and we employ different assumptions, stock-based compensation expense may differ
significantly from what we have recorded in the past. If there are any modifications or cancellations of the underlying unvested securities, we may be required to accelerate, increase or cancel any remaining unearned stock-based compensation
expense. We currently estimate when and if performance-based grants will be earned. If the awards are not considered probable of achievement, no amount of stock-based compensation is recognized. If we consider the award to be probable, expense is
recorded over the estimated service period. To the extent that our assumptions are incorrect, the amount of stock-based compensation recorded will be increased or decreased. To the extent that we grant additional equity securities to employees or we
assume unvested securities in connection with any acquisitions, our stock-based compensation expense will be increased by the additional unearned compensation resulting from those additional grants or acquisitions.

Revenue Recognition

We recognize revenue based on four basic criteria: 1) there is evidence that an arrangement exists; 2) delivery has occurred; 3) the fee is fixed or determinable; and 4) collectability is reasonably
assured. We recognize revenue upon determination that all criteria for revenue recognition have been met. In addition, we do not recognize revenue until the applicable customers acceptance criteria have been met. The criteria are usually met
at the time of product shipment, except for shipments to distributors with rights of return. The portion of revenue from shipments to distributors subject to rights of return is deferred until the agreed upon percentage of return or cancellation
privileges lapse. Revenue from shipments to distributors without return rights is recognized upon shipment. In addition, we record reductions to revenue for estimated allowances such as returns not pursuant to contractual rights, competitive pricing
programs and rebates. These estimates are based on our experience with product returns and the contractual terms of the competitive pricing and rebate programs.

Shipping terms are generally FCA (Free Carrier) shipping point. If actual returns or pricing adjustments exceed our estimates, we would record additional reductions to revenue.

From time to time we generate revenue from the sale of our internally developed IP. We generally recognize revenue from the sale of IP
when all basic criteria outlined above are met.

During the three and nine months ended December 31, 2010, revenues recovered strongly as the
overall market for semiconductor products continued to show improved growth trends. The year over year increase represents the recovery from the recessionary economic conditions and overall softness in demand that was observed during the prior years
and the current pace of infrastructure build out. Though revenues increased year over year, revenues decreased compared to the preceeding three month period due to inventory corrections in the industry. Distributor inventory, on a sell through
basis, has increased to approximately 80 days in the channel. We expect this inventory will be consumed over the next several quarters. We expect revenues for the three months ending March 31, 2011 to be approximately $57.8 million, plus or
minus $1.7 million. This decline is primarily driven by the continued inventory corrections in the industry. Our future revenues could be impacted by the duration and the severity of such inventory corrections and other factors.

The gross profit percentage for the three and nine months ended December 31, 2010
increased to 61.7% and 63.1%, compared to 55.0% and 52.6% for the three and nine months ended December 31, 2009, respectively. The increase in our gross profit percentage for the three and nine months ended December 31, 2010 was primarily
due to favorable product mix, higher licensing revenues, improved manufacturing yields and efficiencies and the overall impact of increased revenues.

The amortization of purchased intangible assets included in cost of revenues during the three and nine months ended December 31, 2010 was $3.3 million and $8.6 million compared to $2.6 million and
$9.5 million for the three and nine months ended December 31, 2009, respectively. The acquisition of TPack has increased our expected amortization of purchased intangible assets included in cost of revenues by approximately $0.6 million per
quarter. The increased expected amortization does not include $1.0 million of in-process R&D. Future acquisitions of businesses may result in substantial additional charges, which may impact the gross profit percentage in future periods.

In January 2011, TPacks supplier of FPGAs announced they acquired a competitor of TPack. This supplier will continue to
provide FPGAs for our current products but not for any future products. We are currently negotiating with another supplier of FPGAs. The process of changing FPGA suppliers could adversely affect the future revenue streams used to value the purchased
intangible assets and contingent consideration of TPack. In which case, we may recognize an impairment of the purchased intangible assets and/or a decrease in the contingent consideration.

Research and
Development. Research and development (R&D) expenses consist primarily of salaries and related costs (including stock-based compensation) of employees engaged in research, design and development activities, costs related to
engineering design tools, subcontracting costs and facilities expenses. The increase in R&D expenses of 21.5% for the three months ended December 31, 2010, compared to the three months ended December 31, 2009 was primarily due to an
increase of $2.7 million in personnel costs, $0.9 million in printed circuit board cost, $0.7 million in technology access fees, $0.6 million in third party foundry costs, $0.4 million in consumable equipment and software cost and $1.1 million in
stock-based compensation charges, offset by $0.6 million decrease in new processor core development costs and $0.7 million increase in customer funded non-recurring engineering payments. The increase in R&D expenses of 28.1% for the nine months
ended December 31, 2010, compared to the nine months ended December 31, 2009 was primarily due to an increase of $10.0 million in personnel costs primarily related to Veloce, $1.5 million in third party foundry costs, $1.5 million in
printed circuit board costs, $1.4 million in technology access fees, $1.1 million in contractor costs and $2.2 million in stock-based compensation charges. We believe that a continued commitment to R&D is vital to our goal of maintaining a
leadership position with innovative products. In addition to our internal R&D programs, our business strategy includes acquiring products, technologies or businesses from third parties. Future acquisitions of products, technologies or businesses
may result in substantial additional on-going R&D costs.

Selling, General and Administrative. Selling, general and
administrative (SG&A) expenses consist primarily of personnel related expenses, professional and legal fees, corporate branding and facilities expenses. The increase in SG&A expenses of 11.1% for the three months ended
December 31, 2010 compared to the three months ended December 31, 2009 was primarily due to an increase of $0.6 million in personnel cost, $0.4 million in contractor cost and $0.3 million in professional service fees. The increase in
SG&A expenses of 10.2% for the nine months ended December 31, 2010 compared to the nine months ended December 31, 2009 was primarily due to an increase of $1.4 million in personnel costs, $1.9 million in contractor cost, $0.5 million
in travel expenses and $0.6 million in stock-based compensation charges, offset by $0.8 million decrease in professional service fees. Future acquisitions of products, technologies or businesses may result in substantial additional on-going SG&A
costs.

The amount of unearned stock-based compensation currently estimated to be expensed from now
through fiscal 2015 related to unvested share-based payment awards at December 31, 2010 is $21.3 million. This expense relates to equity instruments already issued and will not be affected by our future stock price. Vesting of the EBITDA Grants
is subject to (i) the Companys performance as measured by earnings before interest, taxes, depreciation and amortization (EBITDA), and (ii) individual performance as measured by the accomplishment of goals and objectives.
The weighted-average period over which the unearned stock-based compensation is expected to be recognized is approximately 2.1 years. If there are any modifications or cancellations of the underlying unvested securities, we may be required to
accelerate, increase or cancel any remaining unearned stock-based compensation expense. Future stock-based compensation expense will increase to the extent that we grant additional equity awards. The value of these grants cannot be predicted at this
time because it will depend on the number of share-based payments granted and the then current fair values.

Restructuring
Charges. The restructuring charges recorded during the three and nine months ended December 31, 2010 was primarily for employee severances.

Interest and Other
Income and Other-Than-Temporary Impairment, net. Interest income and other-than-temporary impairment, net of management fees and other-than-temporary impairment, reflects interest earned on cash and cash equivalents, short-term investments and
marketable securities as well as realized gains and losses from the sale of short-term investments and impairment charges on investments, less interest expense. The increase in interest income and other-than-temporary impairment, net for the three
and nine months ended December 31, 2010, compared to the three and nine months ended December 31, 2009 was primarily due to gains that were realized from the sale of securities in our investment portfolio in the current fiscal year and an
other-than-temporary impairment charge of $4.0 million in the prior fiscal year. The increase in other income for the three and nine months ended December 31, 2010, compared to the three and nine months ended December 31, 2009 was
primarily due to a $2.0 million impairment for a strategic investment in the prior fiscal year.

Income Taxes. The
federal statutory income tax rate was 35% for the three and nine months ended December 31, 2010 and 2009. The benefit recorded during the three and nine months ended December 31, 2009, related primarily to the gains from discontinued
operations, other comprehensive income and an increase in refundable tax credits. For the three and nine months ended December 31, 2010, the Company had no gains or losses relating to discontinued operations. A provision relating to foreign and
state taxes was provided for the first and second quarter and a corresponding benefit was provided for the third quarter in accordance with ASC 740-270.

Discontinued Operations. We completed the sale of our 3ware storage adapter business (Storage Business) to LSI Corporation on April 21, 2009. Under the Purchase Agreement, we
substantially sold all of the operating assets (other than patents) of our Storage Business. The assets sold included customer contracts, inventory, fixed assets, certain intellectual property and other assets, as well as rights to the name
3ware. The purchase price for the Transaction was approximately $20.0 million, subject to adjustments based on the level of inventory and products in the channel at the closing of the Transaction. After adjustments for the level of
inventory of $0.7 million and products in the channel of $0.8 million, the final adjusted price of the Transaction was approximately $21.5 million. During the fiscal year ended March 31, 2010, we reached an agreement with LSI Corporation to end
the warranty support portion of the Purchase Agreement. We recorded a net gain of $11.4 million from the sale during the fiscal year ended March 31, 2010. During the fiscal year ended March 31, 2010, we recognized a tax charge of
approximately $4.2 million to discontinued operations in connection with the sale of our 3ware storage adapter business and concurrently recorded the same amount as an income tax benefit to continuing operations.

FINANCIAL CONDITION AND LIQUIDITY

As of December 31, 2010, our principal source of liquidity consisted of $190.2 million in cash, cash equivalents and short-term investments. Working capital as of December 31, 2010 was $200.3
million. Total cash, cash equivalents, and short-term investments available-for-sale decreased by $16.4 million during the nine months ended December 31, 2010, primarily due to the acquisition of a business for $31.5 million, repurchases of our
common stock for $23.3 million and purchase of property and equipment of $9.0 million, offset by net cash provided by operations of $35.9 million, net structured stock repurchase proceeds of $5.5 million, proceeds from issuances of common stock of
$4.3 million and proceeds from the sale of a strategic equity investment of $5.0 million. At December 31, 2010, we had contractual obligations not included on our balance sheet totaling $50.6 million, primarily related to facility leases,
engineering design software tool licenses and non-cancelable inventory purchase commitments.

For the nine months ended
December 31, 2010, we generated $35.9 million of cash from our operations compared to generating $8.5 million for the nine months ended December 31, 2009. Our net income of $3.0 million for the nine months ended December 31, 2010
included $29.3 million of non-cash charges consisting of $5.4 million of depreciation, $12.2 million of amortization of purchased intangibles, $12.9 million of stock-based compensation and a credit of $1.2 million related to the capitalization of
prior years mask set costs. Our net loss of $7.4 million for the nine months ended December 31, 2009 included $28.4 million of non-cash charges consisting of $4.9 million of depreciation, $12.5 million of amortization of purchased intangibles,
$10.1 million of stock-based compensation, $4.0 million for marketable securities impairment and $2.0 million impairment of a strategic investment, offset by $5.1 million in tax benefit from other comprehensive income. The remaining change in
operating cash flows for the nine months ended December 31, 2010 primarily reflected decreases in accounts receivable and accounts payable and increases in inventories, other assets, accrued payroll and other accrued liabilities, deferred tax
liability and deferred revenue. Our overall days sales outstanding was 21 days and 32 days for the three months ended December 31, 2010 and March 31, 2010, respectively.

##### Table of Contents

We used $56.9 million of cash from our investing activities during the nine months ended
December 31, 2010, compared to generating $32.4 million during the nine months ended December 31, 2009. During the nine months ended December 31, 2010, we used $21.8 million for short-term investment activities, net, $9.0 million for
the purchase of property and equipment and $31.5 million for the acquisition of a business, offset by proceeds of $5.0 million from the sale of a strategic equity investment. During the nine months ended December 31, 2009, we generated net
proceeds of $16.8 million from short-term investment activities and received proceeds of $21.5 million for the sale of our 3ware storage adapter business, offset by $5.0 million for the purchase of property, equipment and other assets and $1.0
million for the purchase of a strategic investment.

We used $16.3 million of cash for our financing activities during the
nine months ended December 31, 2010, compared to using $16.2 million during the nine months ended December 31, 2009. The major financing use of cash for the nine months ended December 31, 2010 was the funding of our structured stock
repurchase agreements for $10.0 million, $23.3 million for the repurchases of common stock, restricted stock units withheld for taxes of $2.5 million offset by proceeds of $15.5 million from the settlement of structured stock repurchase agreements
and proceeds from issuances of common stock of $4.3 million. The major financing use of cash for the nine months ended December 31, 2009 was the funding of our structured stock repurchase agreements for $31.8 million and $8.1 million in open
market repurchases of our common stock, offset by proceeds of $22.5 million from the settlement of structured stock repurchase agreements and $2.0 million from the issuance of our common stock.

In August 2004, our Board of Directors authorized a stock repurchase program for the repurchase of up to $200.0 million of our common
stock. Under the program, we are authorized to make purchases in the open market or enter into structured agreements. In October 2008, our Board of Directors increased the stock repurchase program by $100.0 million. During the nine months ended
December 31, 2010, approximately 2.1 million shares were repurchased on the open market at a weighted average price of $11.24 per share. During the fiscal year ended March 31, 2010, 1.1 million shares were repurchased on the open
market at a weighted average price of $7.54 per share. All repurchased shares are retired upon delivery to us. In November 2010, we entered into a 10(b)-5 plan to repurchase up to 1.0 million shares of our common stock at various price
parameters. The plan will expire on May 31, 2011. As of December 31, 2010, we repurchased approximately 20,000 shares at a weighted average price of $10.21 per share under this 10(b)-5 plan. In January 2011, the Board approved an
additional 3.0 million shares to be repurchased under a 10(b)-5 plan.

We also utilize structured stock repurchase
agreements to buy back shares which are prepaid written put options on our common stock. We pay a fixed sum of cash upon execution of each agreement in exchange for the right to receive either a pre-determined amount of cash or stock depending on
the closing market price of our common stock on the expiration date of the agreement. Upon expiration of each agreement, if the closing market price of our common stock is above the pre-determined price, we will have our cash investment returned
with a premium. If the closing market price is at or below the pre-determined price, we will receive the number of shares specified at the agreement inception. Any cash received, including the premium, is treated as additional paid in capital on the
balance sheet.

During the nine months ended December 31, 2010, we entered into structured stock repurchase agreements
totaling $10.0 million. For those agreements that settled during the nine months ended December 31, 2010, we received $15.5 million in cash and 0.5 million in shares of our common stock at an effective purchase price of $10.01 per share
from the settled structured stock repurchase agreements. During the fiscal year ended March 31, 2010, we entered into structured stock repurchase agreements totaling $41.8 million. For those agreements that settled during the fiscal year ended
March 31, 2010, we received $27.8 million in cash and 0.7 million shares of our common stock at an effective purchase price of $7.25 per share from the settled structured stock repurchase agreements. At December 31, 2010, we had no
outstanding structured stock repurchase agreements and approximately $64.1 million remaining available to repurchase shares under the stock repurchase program. For additional information, refer to the condensed consolidated statement of cash flows.

On November 8, 2010, we amended the merger and certain other agreements with Veloce, initially entered into on
May 17, 2009, pursuant to which Veloce has agreed to perform product development work for us on an exclusive basis for up to five years for cash and other consideration, including a warrant to purchase shares of our common stock, which will
vest quarterly through December 2012.

Under the merger agreement between us and Veloce, we agreed to acquire Veloce if
certain performance milestones and delivery schedules set forth under the merger and other agreements are achieved. We also have the unilateral option to acquire Veloce in the event Veloce fails to meet the milestones and delivery schedules. Should
we acquire Veloce pursuant to the merger agreement, the purchase price is estimated to be in the range of approximately $7 million up to approximately $135 million, subject to adjustments. The final price would be based upon the achievement and
timing of achieving multiple performance milestones and currently is not determinable. We will determine the form of consideration used for the merger, cash or our stock, at the time of the merger. The merger agreement contains customary
representations, warranties and covenants and may be terminated upon mutual agreement of the parties or unilaterally by us or Veloce if the other party fails to meet certain conditions set forth in the agreement. The amended agreements permit us to
appoint two individuals to serve on Veloces Board of Directors and Board committees.

In addition, we provided Veloce a promissory note of $1.5 million to be forgiven over eight
quarters starting on March 31, 2011. If Veloce commits a material breach of the merger agreement, the outstanding principal amount of the note and accrued interest is due to us. If we commit a material breach of the merger agreement, the
outstanding principal amount of the note and accrued interest is to be forgiven by us. The promissory note is eliminated in consolidation. Pursuant to the product development agreement, as amended, we will pay Veloce $2.3 million per quarter for up
to twelve consecutive quarters in order to assist Veloce in meeting its expenses to perform its obligations under the agreement and we will recognize the payments as research and development expenses when incurred.

On September 17, 2010, we acquired TPack, a Danish Corporation organized under the laws of Denmark, in accordance with the terms and
conditions of the stock purchase agreement dated August 17, 2010. The total consideration paid at the closing of the transaction was approximately $32 million. The former TPack shareholders may also earn up to approximately $5 million in
additional consideration, subject to the achievement of certain revenue and performance milestones by TPack within 18 months after the acquisition. Approximately $5 million was placed in escrow to secure the indemnification obligation of TPack. In
addition, we recorded acquisition related transaction costs of $0.9 million, which were included in selling, general and administrative expense.

In July 2010, we entered into an agreement for a multi-year license with a leading semiconductor IP supplier, where the components of the licensed technology are expected to be delivered over multiple
years. The Company does not regard the license as significant to its current business. We intend to use the license to develop new products. The aggregate licensing fees are approximately $18.1 million and are payable over five years. This is in
addition to a technology license agreement we entered into in March 2010, for approximately $4.4 million which is payable over approximately one year.

The following table summarizes our contractual operating leases and other purchase commitments as of December 31, 2010 (in thousands):

The amount in the table above does not include an estimated $0.6 million as it relates to accounting for
uncertainty in income taxes.

We believe that our available cash, cash equivalents and short-term investments will be
sufficient to meet our capital requirements and fund our operations for at least the next 12 months, although we could elect or could be required to raise additional capital during such period. There can be no assurance that debt or equity financing
will be available on commercially reasonable terms or at all.

OFF-BALANCE SHEET ARRANGEMENTS

We did not have any off-balance sheet arrangements as of December 31, 2010 or March 31, 2010.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

Market risk is the potential loss arising from adverse changes in market rates and prices, such as foreign currency exchange rates, interest rates and a decline in the stock market. The current turbulence
in the U.S. and global financial markets has caused a decline in stock values across all industries. We are exposed to market risks related to changes in interest rates and foreign currency exchange rates.

We maintain an investment portfolio of various holdings, types of instruments and maturities. These securities are classified as
available-for-sale and, consequently, are recorded on our consolidated balance sheets at fair value with unrealized gains or losses

##### Table of Contents

reported as a separate component of accumulated other comprehensive income or loss. We have established guidelines relative to diversification and maturities that attempt to maintain safety and
liquidity. These guidelines are periodically reviewed and modified to take advantage of interest rate trends. We invest our excess cash in debt instruments of the U.S. Treasury, corporate bonds, mortgage-backed and asset backed securities, mutual
funds and closed-end bond funds, with credit ratings as specified in our investment policy. We also have invested in preferred stocks, which pay quarterly fixed rate dividends. We generally do not utilize derivatives to hedge against increases in
interest rates which decrease market values.

We are exposed to market risk as it relates to changes in the market value of
our investments. At December 31, 2010, our investment portfolio included short-term securities classified as available-for-sale investments with an aggregate fair market value of $105.0 million and a cost basis of $97.2 million. These
securities are subject to interest rate risk, as well as credit risk and liquidity risk, and will decline in value if interest rates increase or an issuers credit rating or financial condition is decreased.

The following table presents the hypothetical changes in fair value of our short-term investments held at December 31, 2010 (in
thousands):

The modeling technique used measures the change in fair market value arising from selected potential changes
in interest rates. Market changes reflect immediate hypothetical parallel shifts in the yield curve of plus or minus 50 basis points, 100 basis points, and 150 basis points. While this modeling technique provides a measure of our exposure to market
risk, the current economic turbulence could cause interest rates to shift by more than 150 basis points.

We also invest in
equity instruments of private companies for business and strategic purposes. These investments are valued based on our historical cost, less any recognized impairments. The estimated fair values are not necessarily representative of the amounts that
we could realize in a current transaction.

We generally conduct business, including sales to foreign customers, in U.S.
dollars, and as a result, we have limited foreign currency exchange rate risk. However, we have periodically entered into forward currency exchange contracts to hedge our overseas monthly operating expenses when deemed appropriate. We did not enter
into any forward currency exchange contract during the nine months ended December 31, 2010. Gains and losses on foreign currency forward contracts that are designated and effective as hedges of anticipated transactions, for which a firm
commitment has been attained, are deferred and included in the basis of the transaction in the same period that the underlying transaction is settled. Gains and losses on any instruments not meeting the above criteria are recognized in income or
expenses in the consolidated statements of operations in the current period. The effect of an immediate 10% change in foreign exchange rates would not have a material impact on our financial condition or results of operations.



|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports we
file or submit with the SEC pursuant to the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms and that such information is accumulated and communicated to our management,
including our Chief Executive Officer (CEO) and Chief Financial Officer (CFO), as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures,
management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the
cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will
succeed in achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the
inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

As required by Exchange Act Rule 13a-15(b), we conducted an evaluation, under the supervision and with the participation of our
management, including our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2010. Based on the foregoing, our CEO and CFO concluded that our disclosure controls and
procedures were effective at the reasonable assurance level.

PART II. OTHER INFORMATION



|ITEM 1. | LEGAL PROCEEDINGS
|------- | -----------------

The
information set forth under Note 7 of Notes to Consolidated Financial Statements, included in Part I, Item 1 of this report, is incorporated herein by reference.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

Before
deciding to invest in us or to maintain or increase your investment, you should carefully consider the risks described below, in addition to the other information contained in this report and in our other filings with the SEC. We update our
descriptions of the risks and uncertainties facing us in our periodic reports filed with the SEC. The risks and uncertainties described below and in our other filings are not the only ones facing us. Additional risks and uncertainties not presently
known to us or that we currently deem immaterial may also affect our business. If any of these known or unknown risks or uncertainties actually occurs, our business, financial condition and results of operations could be seriously harmed. In that
event, the market price for our common stock could decline and you may lose all or part of your investment. The risks and uncertainties set forth below with an asterisk (*) next to the title contain changes to the description of the
risks and uncertainties associated with our business as previously disclosed in Item 1A to our Annual Report on Form 10-K for the fiscal year ended March 31, 2010 filed with the SEC on May 11, 2010.

*If we are unable to timely develop new products or new generations and versions of our existing products to replace our current
products, our operating results and competitive position will be materially harmed.

Our industry is characterized by
intense competition, rapidly evolving technology and continually changing customer requirements. These factors could render our existing products obsolete. Accordingly, our ability to compete in the future will depend in large part on our ability to
identify and develop new products or new generations and versions of our existing products that achieve market acceptance on a timely and cost-effective basis, and to respond to changing requirements. If we are unable to do so, our business,
operating results and financial condition will be negatively affected.

The successful development and market acceptance of
our products depend on a number of factors, including, but not limited to:



| |  |  | our accurate prediction of changing customer requirements;
| | - |  | ----------------------------------------------------------



| |  |  | timely development of new designs;
| | - |  | ----------------------------------



| |  |  | timely qualification and certification of our products for use in electronic systems;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | commercial acceptance and production of the electronic systems into which our products are incorporated;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | availability, quality, price, performance, and size of our products relative to competing products and technologies;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | our customer service and support capabilities and responsiveness;
| | - |  | -----------------------------------------------------------------



| |  |  | successful development of relationships with existing and potential new customers;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | successful development of relationships with key developers of advanced digital semiconductors;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | changes in technology and industry standards; and
| | - |  | -------------------------------------------------



| |  |  | rapidly changing consumer preferences.
| | - |  | --------------------------------------

In addition, on November 8, 2010, we amended certain agreements with Veloce, initially entered into on May 17, 2009, pursuant to which Veloce agreed to perform product development work for us on
an exclusive basis for up to five years for cash and other consideration, including a warrant to purchase shares of our common stock, which will vest quarterly through December 2012. Under the merger agreement with Veloce, as amended, we agreed to
acquire Veloce if certain performance milestones and delivery schedules set forth under the merger and other agreements are achieved. We also have the unilateral option to acquire Veloce in the event Veloce fails to meet the milestones and delivery
schedules. Should we acquire Veloce pursuant to the merger agreement, the purchase price is estimated to be in the range of approximately $7 million up to approximately $135 million, subject to adjustments. The final price would be based upon the
achievement and timing of achieving multiple performance milestones and currently is not determinable. We also provided Veloce a promissory note of $1.5 million to be forgiven over eight quarters starting on March 31, 2011. We will also pay
Veloce $2.3 million per quarter for up to twelve consecutive quarters in order to assist Veloce in meeting its expenses to perform its obligations under the agreement.

Our arrangement with Veloce may not result in the development of any new technologies or products. Moreover, products we have recently developed and which we are currently developing may not achieve
market acceptance. If these products fail to achieve market acceptance, or if we fail to timely develop new products that achieve market acceptance, our business, financial condition and operating results will be materially harmed.

*Our dependence on third-party manufacturing and supply relationships increases the
risk that we will not have an adequate supply of products to meet demand or that our cost of materials will be higher than expected.

We depend upon third parties to manufacture, assemble, package or test certain of our products. As a result, we are subject to risks associated with these third parties, including:



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



| |  |  | inadequate manufacturing yields and excessive costs;
| | - |  | ----------------------------------------------------



| |  |  | difficulties selecting and integrating new subcontractors;
| | - |  | ----------------------------------------------------------



| |  |  | potential lack of adequate capacity at the foundry during periods of excess demand, resulting in significant increased in lead-time requirements and
production delays;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| |  |  | potential increases in prices;
| | - |  | ------------------------------



| |  |  | potential instability in countries where third-party manufacturers are located; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | potential misappropriation of our intellectual property.
| | - |  | --------------------------------------------------------

Our outside foundries generally manufacture our products on a purchase order basis, and we have few long-term supply arrangements with these suppliers. We have less control over delivery schedules,
manufacturing yields and costs than competitors with their own fabrication facilities. A manufacturing disruption or capacity constraint experienced by one or more of our outside foundries or a disruption of our relationship with an outside foundry,
including discontinuance of our products by that foundry, would negatively impact the production of certain of our products for a substantial period of time.

As our third-party manufacturing suppliers extend their lead time requirements, we will likely need to also extend our lead time requirements to our customers. This could cause our customer to lower their
competitive assessment of us as a supplier and as a result, we may not be considered for future design awards.

Our IC
products are generally only qualified for production at a single foundry. These suppliers can allocate, and in the past have allocated, capacity to the production of other companies products while reducing deliveries to us on short notice.
There is also the potential that they may discontinue manufacturing our products or go out of business. Because establishing relationships, designing or redesigning ICs, and ramping production with new outside foundries may take over a year, there
is no readily available alternative source of supply for these products.

Difficulties associated with adapting our technology
and product design to the proprietary process technology and design rules of outside foundries can lead to reduced yields of our IC products. The process technology of an outside foundry is typically proprietary to the manufacturer. Since low yields
may result from either design or process technology failures, yield problems may not be effectively determined or resolved until an actual product exists that can be analyzed and tested to identify process sensitivities relating to the design rules
that are used. As a result, yield problems may not be identified until well into the production process, and resolution of yield problems may require cooperation between us and our manufacturer. This risk could be compounded by the offshore location
of certain of our manufacturers, increasing the effort and time required to identify, communicate and resolve manufacturing yield problems. Manufacturing defects that we do not discover during the manufacturing or testing process may lead to costly
product recalls. These risks may lead to increased costs or delayed product delivery, which would harm our profitability and customer relationships.

If the foundries or subcontractors we use to manufacture our products discontinue the manufacturing processes needed to meet our demands, or fail to upgrade their technologies needed to manufacture our
products, we may be unable to deliver products to our customers, which could materially adversely affect our operating results. The transition to the next generation of manufacturing technologies at one or more of our outside foundries could be
unsuccessful or delayed.

Our requirements typically represent a very small portion of the total production of the third-party
foundries. As a result, we are subject to the risk that a producer will cease production of an older or lower-volume process that it uses to produce our parts. We cannot assure you that our external foundries will continue to devote resources to the
production of parts for our products or continue to advance the process design technologies on which the manufacturing of our products are based. Each of these events could increase our costs, lower our gross margin, cause us to hold more
inventories or materially impact our ability to deliver our products on time. As our volumes decrease with any third-party foundry, the likelihood of unfavorable pricing increases.

Some companies that supply our customers are similarly dependent on a limited number of suppliers to produce their products. These other
companies products may be designed into the same networking equipment into which our products are designed. Our order levels could be reduced materially if these companies are unable to access sufficient production capacity to produce in
volumes demanded by our customers because our customers may be forced to slow down or halt production on the equipment into which our products are designed.

*We may experience difficulties in transitioning to smaller geometry process
technologies or in achieving higher levels of design integration and that may result in reduced manufacturing yields, delays in product deliveries and increased expenses.

As smaller line width geometry processes become more prevalent, we expect to integrate greater levels of functionality into our IC
products and to transition our IC products to increasingly smaller geometries. This transition will require us to redesign certain products and will require us and our foundries to migrate to new manufacturing processes for our products.

We may not be able to achieve higher levels of design integration or deliver new integrated products on a timely basis. We periodically
evaluate the benefits, on a product-by-product basis, of migrating to smaller geometry process technologies to reduce our costs and increase performance, and we have designed IC products to be manufactured at as little as .04 micron geometry
processes. We have experienced some difficulties in shifting to smaller geometry process technologies and new manufacturing processes. These difficulties resulted in reduced manufacturing yields, delays in product deliveries and increased expenses.
The transition to smaller geometries is inherently more expensive and as we manufacture more products using smaller geometries, the incremental costs could have an adverse impact on our earnings. We may face similar difficulties, delays and expenses
as we continue to transition our IC products to smaller geometry processes. We are dependent on our relationships with our foundries to transition to smaller geometry processes successfully. We cannot assure you that our foundries will be able to
effectively manage the transition or that we will be able to maintain our relationships with our foundries. If we or our foundries experience significant delays in this transition or fail to implement this transition, our business, financial
condition and results of operations could be materially and adversely affected.

The gross margins for our products
could decrease rapidly or not increase as forecasted, which will negatively impact our operating results.

The gross
margins for our solutions have historically declined over time. Factors that we expect to cause downward pressure on the gross margins for our products include competitive pricing pressures, the cost sensitivity of our customers, particularly in the
higher-volume markets, new product introductions by us or our competitors, and other factors. From time to time, for strategic reasons, we may accept orders at less than optimal gross margins in order to facilitate the introduction of, or, market
penetration of our new or existing products. To maintain acceptable operating results, we will need to offset any reduction in gross margins of our products by reducing costs, increasing sales volume, developing and introducing new products and
developing new generations and versions of existing products on a timely basis. If the gross margins for our products decline or not increase as forecasted and we are unable to offset those reductions, our business, financial condition and operating
results will be materially harmed.

*The current economic circumstances and uncertain political conditions could harm
our revenues, operating results and financial condition.

The economies of the United States and other developed
countries are currently coming out of a recession. We cannot predict either if this economic recovery will continue or retreat back into a recession.

The recent recession has caused a decline in our near term revenues and it will take some time to return to our previous levels. Our current operating plans are based on assumptions concerning levels of
consumer and corporate spending. If global and domestic economic and market conditions persist or deteriorate, we may experience further material impacts on our business, operating results and financial condition which could result in a decline in
the price of our common stock. If economic conditions worsen, we may have to implement additional cost reduction measures or delay certain research and development spending.

We maintain an investment portfolio of various holdings, types of instruments and maturities. These securities are generally classified as available-for-sale and, consequently, are recorded on our
consolidated balance sheets at fair value with unrealized gains or losses reported as a separate component of accumulated other comprehensive income. Our portfolio primarily includes fixed income securities, mutual funds and preferred stocks, the
values of which are subject to market price volatility. The deterioration of these market prices has had an unfavorable impact on our portfolio and has caused us to record impairment charges to our earnings. During the fiscal years ended
March 31, 2010 and 2009, we recorded other-than-temporary impairment charges of $4.1 million and $17.1 million, respectively. If the market prices continue to decline or securities continue to be in a loss position over time, we may recognize
additional impairments in the fair value of our investments.

Adverse economic and market conditions could also harm our
business by negatively affecting the parties with whom we do business, including our business partners, our customers and our suppliers. These conditions could impair the ability of our customers to pay for products they have purchased from us. As a
result, allowances for doubtful accounts and write-offs of accounts receivable from our customers may increase. In addition, our suppliers may experience financial difficulties that could negatively affect their operations and their ability to
supply us with the parts we need to manufacture our products.

We have invested in privately-held companies, many of which can still be considered in
startup or developmental stages. These investments are inherently risky as the market for the technologies or products they have under development are typically in the early stages and may never materialize. We could lose all or substantially all of
the value of our investments in these companies and, in some cases, we have lost all or substantially all of the value of our investment in such entities.

*Our operating results may fluctuate because of a number of factors, many of which are beyond our control.

If our operating results are below the expectations of public market analysts or investors, then the market price of our common stock could decline. Some of the factors that affect our quarterly and

*Our business, financial condition and operating results would be harmed if we do not achieve anticipated revenues.

We can have revenue shortfalls for a variety of reasons, including:



| |  |  | shortages of raw materials or production capacity constraints that lead our suppliers to allocate available supplies or capacity to other customers,
which may disrupt our ability to meet our production obligations;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays in the availability of our products or our customers products;
| | - |  | ----------------------------------------------------------------------

| |  |  | delays when our customers are transitioning from old products to new products;
| | - |  | ------------------------------------------------------------------------------



| |  |  | a decrease in demand for our products or our customers products;
| | - |  | -----------------------------------------------------------------



| |  |  | a decline in the financial condition or liquidity of our customers or their customers;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | the failure of our products to be qualified in our customers systems or certified by our customers;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | excess inventory of our products held by our customers, resulting in a reduction in their order patterns as they work through the excess inventory of
our products;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | fabrication, test, product yield, or assembly constraints for our products that adversely affect our ability to meet our production obligations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the failure of one of our subcontract manufacturers to perform its obligations to us;
| | - |  | -------------------------------------------------------------------------------------

Our business is characterized by short-term orders and shipment schedules. Customer orders typically can be cancelled or rescheduled without significant penalty to the customer. Because we do not have
substantial non-cancellable backlog, we typically plan our production and inventory levels based on internal forecasts of customer demand, which is highly unpredictable and can fluctuate substantially. Customer orders for our products typically have
non-standard lead times, which make it difficult for us to predict revenues and plan inventory levels and production schedules. If we are unable to plan inventory levels and production schedules effectively, our business, financial condition and
operating results could be materially harmed.

From time to time, in response to anticipated long lead times to obtain
inventory and materials from our outside contract manufacturers, suppliers and foundries, we may order materials in advance of anticipated customer demand. This advance ordering has in the past and may in the future result in excess inventory levels
or unanticipated inventory write-downs if expected orders fail to materialize, or other factors render our products less marketable. If we are forced to hold excess inventory or we incur unanticipated inventory write-downs, our financial condition
and operating results could be materially harmed.

Our expense levels are relatively fixed in the short-term and are based on
our expectations of future revenues. We have limited ability to reduce expenses quickly in response to any revenue shortfalls. Changes to production volumes and impact of overhead absorption may result in a decline in our financial condition or
liquidity.

Our business substantially depends upon the continued growth of the technology sector and the Internet.

The technology equipment industry is cyclical and has in the past experienced significant and extended downturns. The
recent downturn was significant and we cannot predict if the current improvement is sustainable in the near future. A substantial portion of our business and revenue depends on the continued growth of the technology sector and the Internet. We sell
our communications IC products primarily to communications equipment manufacturers that in turn sell their equipment to customers that depend on the growth of the Internet. The past downturn has caused a reduction in capital spending on information
technology. While we are beginning to see indications of improvement, there are no guarantees that this growth will sustain, resulting in potential volatility. If there is another downturn, our business, operating results and financial condition may
be materially harmed.

*The loss of one or more key customers, the diminished demand for our products from a key
customer, or the failure to obtain certifications from a key customer or its distribution channel could significantly reduce our revenues and profits.

A relatively small number of customers have accounted for a significant portion of our revenues in any particular period. We have no long-term volume purchase commitments from our key customers. One or
more of our key customers may discontinue operations as a result of consolidation, liquidation or otherwise. Reductions, delays and cancellation of orders from our key customers or the loss of one or more key customers could significantly reduce our
revenues and profits. We cannot assure you that our current customers will continue to place orders with us, that orders by existing customers will continue at current or historical levels or that we will be able to obtain orders from new customers.

##### Table of Contents

Our ability to maintain or increase sales to key customers and attract significant new
customers is subject to a variety of factors, including:



| |  |  | supply constraints and manufacturing delays by our outside foundries may result in significantly reduced volumes and delayed deliveries of our
products;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | customers may stop incorporating our products into their own products with limited notice to us and may suffer little or no penalty as a result of such
action;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | customers or prospective customers may not incorporate our products into their future product designs;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | design wins (as explained below) with customers or prospective customers may not result in sales to such customers;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | the introduction of new products by customers may occur later or be less successful in the market than planned;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | we may successfully design a product to customer specifications but the customer may not be successful in the market;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | sales of customer product lines incorporating our products may rapidly decline or such product lines may be phased out;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | our agreements with customers typically are non-exclusive and do not require them to purchase a minimum quantity of our products;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | many of our customers have pre-existing relationships with our current or potential competitors that may cause our customers to switch from using our
products to using competing products;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | some of our OEM customers may develop products internally that would replace our products;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | we may not be able to successfully develop relationships with additional network equipment vendors;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | our relationships with some of our larger customers may deter other potential customers (who compete with these customers) from buying our products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the impact of terminating certain sales representatives or sales personnel as a result of a Company workforce reduction or otherwise; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | some of our customers and prospective customers may become less viable or fail.
| | - |  | -------------------------------------------------------------------------------

The occurrence of any one of the factors above could have a material adverse effect on our business, financial condition and results of
operations.

There is no guarantee that design wins will become actual orders and sales.

A design win occurs when a customer or prospective customer notifies us that our product has been selected to be integrated
with the customers product. There can be delays of several months or more between the design win and when a customer initiates actual orders of our product. Following a design win, we will commit significant resources to the integration of our
product into the customers product before receiving the initial order. Receipt of an initial order from a customer following a design win, however, is dependent on a number of factors, including the success of the customers product, and
cannot be guaranteed. The design win may never result in an actual order or sale.

*Any significant order cancellations
or order deferrals could cause unplanned inventory growth resulting in excess inventory which may adversely affect our operating results.

Our customers may increase orders during periods of product shortages or cancel orders if their inventories are too high. Major inventory corrections by our customers are not uncommon and can last for
significant periods of time and affect demand for our products. Customers may also cancel or delay orders in anticipation of new products or for other reasons. Cancellations or deferrals could cause us to hold excess inventory, which could reduce
our profit margins by reducing sales prices, incurring inventory write-downs or writing off additional obsolete products.

The
book-to-bill ratio is commonly used by investors to compare and evaluate technology and semiconductor companies. The book-to-bill ratio is a demand-to-supply ratio that compares the total amount of orders received to the total amount of orders
filled. This ratio tells whether the company has more orders than it delivered (if greater than 1), has the same amount of orders that it delivered (equals 1), or has less orders than it delivered (under 1). Though the ratio provides an indicator of
whether orders are rising or falling, it does not consider the timing of, or if the order will result in future revenues. Our book-to-bill ratio at December 31, 2010 and 2009 was 0.9 and 1.0, respectively.

The increasing lead times from our suppliers cause us to make commitments for inventory purchases earlier in our production cycle which
in turn increases our risk of excess inventory. In addition, some of our suppliers are delivering based on allocations which



43



---

##### Table of Contents

in turn causes us to increase our inventory levels. We must balance our inventory levels between the risk of losing a significant customer to a competitor because we cannot meet our
customers requirements and the risk of having excess inventory if a significant order is cancelled.

Inventory
fluctuations could affect our results of operations and restrict our ability to fund our operations. Inventory management remains an area of focus as we balance the need to maintain strategic inventory levels to ensure competitive lead times, meet
customer expectations and guard against the risk of inventory obsolescence because of changing technology and customer requirements.

We generally recognize revenue upon shipment of products to a customer. If a customer refuses to accept shipped products or does not pay for these products, we could miss future revenue projections or
incur significant charges against our income, which could materially and adversely affect our operating results.

Our
customers products typically have lengthy design cycles. A customer may decide to cancel or change its product plans, which could cause us to lose anticipated sales.

After we have developed and delivered a product to a customer, the customer will usually test and evaluate our product prior to designing
its own equipment to incorporate our product. Our customers may need more than six months to test, evaluate and adopt our product and an additional nine months or more to begin volume production of equipment that incorporates our product. Due to
this lengthy design cycle, we may experience significant delays from the time we increase our operating expenses and make investments in inventory until the time that we generate revenue from these products. It is possible that we may never generate
any revenue from these products after incurring such expenditures. Even if a customer selects our product to incorporate into its equipment, we cannot guarantee that the customer will ultimately market and sell its equipment or that such efforts by
our customer will be successful. The delays inherent in this lengthy design cycle increases the risk that a customer will decide to cancel or change its product plans. Such a cancellation or change in plans by a customer could cause us to lose sales
that we had anticipated. While our customers design cycles are typically long, some of our product life cycles tend to be short as a result of the rapidly changing technology environment in which we operate. As a result, the resources devoted
to product sales and marketing may not generate material revenue for us, and from time to time, we may need to write off excess and obsolete inventory. If we incur significant marketing expenses and investments in inventory in the future that we are
not able to recover, and we are not able to mitigate those expenses, our operating results could be adversely affected. In addition, if we sell our products at reduced prices in anticipation of cost reductions but still hold higher cost products in
inventory, our operating results would be harmed.

An important part of our strategy is to focus on the markets for
communications equipment. If we change strategy or are unable to further expand our share of these markets or react timely or properly to emerging trends, our revenues may not grow and could decline.

Our markets frequently undergo transitions in which products rapidly incorporate new features and performance standards on an
industry-wide basis. If our products are unable to support the new features or performance levels required by OEMs in these markets, or if our products fail to be certified by OEMs, we would lose business from an existing or potential customer and
may not have the opportunity to compete for new design wins or certification until the next product transition occurs. If we fail to develop products with required features or performance standards, or if we experience a delay as short as a few
months in certifying or bringing a new product to market, or if our customers fail to achieve market acceptance of their products, our revenues could be significantly reduced for a substantial period.

We expect a significant portion of our revenues to continue to be derived from sales of products based on current, widely accepted
transmission standards. If the communications market evolves to new standards, we may not be able to successfully design and manufacture new products that address the needs of our customers or gain substantial market acceptance.

The sale of our 3ware storage adapter business to LSI Corporation marks a change in our strategy. This change, or any further changes we
might make, could have a significant impact on our business, financial condition and results of operations while we are implementing our new strategy.

If we do not identify and pursue the correct emerging trends and align ourselves with the correct market leaders, we may not be successful and our business, financial condition and results of operations
could be materially and adversely affected.

Customers for our products generally have substantial technological capabilities
and financial resources. Some customers have traditionally used these resources to internally develop their own products. The future prospects for our products in these markets are dependent upon our customers acceptance of our products as an
alternative to their internally developed products. Future prospects also are dependent upon acceptance of third-party sourcing for products as an alternative to in-house development. Network equipment vendors may in the future continue to use
internally developed components. They also may decide to develop or acquire components, technologies or products that are similar to, or that may be substituted for, our products.

##### Table of Contents

If our network equipment vendor customers fail to accept our products as an alternative, if
they develop or acquire the technology to develop such components internally rather than purchase our products, or if we are otherwise unable to develop or maintain strong relationships with them, our business, financial condition and results of
operations would be materially and adversely affected.

*Our business strategy contemplates the acquisition of other
companies, products and technologies. Merger and acquisition activities involve numerous risks and we may not be able to address these risks successfully without substantial expense, delay or other operational or financial problems that could
disrupt our business and harm our results of operations and financial condition.

Acquiring products, technologies or
businesses from third parties or making additional investments in companies we have already have an interest in is part of our long-term business strategy. The risks involved with merger and acquisition activities include:



| |  |  | potential dilution to our stockholders;
| | - |  | ---------------------------------------



| |  |  | use of a significant portion of our cash reserves;
| | - |  | --------------------------------------------------



| |  |  | diversion of managements attention from our core business;
| | - |  | -----------------------------------------------------------



| |  |  | failure to integrate or potential loss of key employees, particularly those of the acquired organizations.
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | difficulty in completing an acquired companys in-process research or development projects;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | amortization of acquired intangible assets and deferred compensation;
| | - |  | ---------------------------------------------------------------------



| |  |  | customer dissatisfaction or performance problems with an acquired companys products or services;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | adverse effects on existing business relationships with suppliers and customers;
| | - |  | --------------------------------------------------------------------------------



| |  |  | costs associated with acquisitions or mergers;
| | - |  | ----------------------------------------------



| |  |  | difficulties associated with combining or integrating acquired companies, purchased operations, products or technologies;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties and risks associated with entering and competing in markets that are unfamiliar to us;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | ability of the acquired companies to meet their financial projections; and
| | - |  | --------------------------------------------------------------------------



| |  |  | assumption of unknown liabilities, or other unanticipated costs, events or circumstances.
| | - |  | -----------------------------------------------------------------------------------------

In addition, in the event of any such investments or acquisitions, we could



| |  |  | issue stock that would dilute our current stockholders percentage ownership;
| | - |  | -----------------------------------------------------------------------------



| |  |  | incur debt;
| | - |  | -----------



| |  |  | assume liabilities;
| | - |  | -------------------



| |  |  | incur amortization or impairment expenses related to goodwill and other intangible assets; or
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | incur large and immediate write-offs.
| | - |  | -------------------------------------

Any of these risks could materially harm our business, financial condition and results of operations.

As with past acquisitions, future acquisitions could adversely affect operating results. In particular, acquisitions may materially and adversely affect our results of operations because they may require
large one-time charges or could result in increased debt or contingent liabilities, adverse tax consequences, substantial additional depreciation or deferred compensation charges. Our past purchase acquisitions required us to capitalize significant
amounts of goodwill and purchased intangible assets. As a result of the slowdown in our industry and reduction of our market capitalization, we have been required to record significant impairment charges against these assets as noted in our
financial statements. In the fiscal year ended March 31, 2009 we recorded a goodwill impairment charge of $223.0 million to continuing operations. The goodwill impaired was previously assigned to the Process and Transport reporting units in the
amounts of $101.5 million, $121.5 million, respectively. In the fiscal years ended March 31, 2009 and 2008, we recorded goodwill impairment charges to discontinued operations of $41.1 million and $71.5 million, respectively, for the Store
reporting unit. These market conditions continuously change and it is difficult to project how long these current uncertain economic conditions may last. These conditions have caused a decline in our near term revenues and it will take some time to
ramp back up to our previous levels. Additionally, market values had deteriorated which has had an unfavorable impact on our valuations which are part of the goodwill and purchased intangible asset impairment tests. There can be no assurances that
market conditions will not deteriorate further or that our market capitalization will not decline further. At December 31, 2010, we had $42.2 million of goodwill and purchased intangible assets. We cannot assure you that we will not be required
to take significant charges as a result of impairment to the carrying value of the purchased intangible assets, due to further adverse changes in market conditions.

On September 17, 2010, we completed the acquisition of TPack for $32 million in cash, exclusive of $0.5 million cash acquired, and potentially up to an additional $5 million if certain
performance milestones are achieved. In conjunction with the acquisition, we



45



---

##### Table of Contents

recorded $23.7 million in amortizable intangible assets and $13.8 million in goodwill. If the financial forecasts and other assumptions used to evaluate the acquisition do not materialize as
expected, we could incur an impairment charge for up to the entire value the intangible assets and goodwill.

We cannot assure
you that we will be able to successfully integrate TPacks business, products, technologies or personnel or any additional businesses, products, technologies or personnel that we might acquire.

In January 2011, TPacks supplier of FPGAs announced they acquired a competitor of TPack. This supplier will continue to provide
FPGAs for our current products but not for any future products. We are currently negotiating with another supplier of FPGAs. The process of changing FPGA suppliers could adversely affect the future revenue streams used to value the purchased
intangible assets and contingent consideration of TPack. In which case, we may recognize an impairment of the purchased intangible assets and/or a decrease in the contingent consideration.

Our industry and markets are subject to consolidation, which may result in stronger competitors, fewer customers and reduced
demand.

There has been industry consolidation among communications IC companies, network equipment companies and
telecommunications companies in the past. We expect this consolidation to continue as companies attempt to strengthen or hold their positions in evolving markets. Consolidation may result in stronger competitors, fewer customers and reduced demand,
which in turn could have a material adverse effect on our business, operating results, and financial condition.

Our
operating results are subject to fluctuations because we rely heavily on international sales.

International sales
account for a significant part of our revenues and may account for an increasing portion of our future revenues. The revenues we derive from international sales may be subject to certain risks, including:



| |  |  | foreign currency exchange fluctuations;
| | - |  | ---------------------------------------



| |  |  | changes in regulatory requirements;
| | - |  | -----------------------------------



| |  |  | tariffs, rising protectionism and other barriers;
| | - |  | -------------------------------------------------



| |  |  | timing and availability of export licenses;
| | - |  | -------------------------------------------



| |  |  | political and economic instability;
| | - |  | -----------------------------------



| |  |  | difficulties in staffing and managing foreign operations;
| | - |  | ---------------------------------------------------------



| |  |  | difficulties in managing distributors;
| | - |  | --------------------------------------



| |  |  | difficulties in obtaining governmental and export approvals for communications, processors and other products;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | reduced or uncertain protection for intellectual property rights in some countries;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | longer payment cycles and difficulties to collect accounts receivable in some countries;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | burdens of complying with a wide variety of complex foreign laws and treaties;
| | - |  | ------------------------------------------------------------------------------



| |  |  | potentially adverse tax consequences; and
| | - |  | -----------------------------------------



| |  |  | an uncertain economic condition that may trail any improvements in the United States.
| | - |  | -------------------------------------------------------------------------------------

We are subject to risks associated with the imposition of legislation and regulations relating to the import or export of high technology
products. We cannot predict whether quotas, duties, taxes or other charges or restrictions upon the importation or exportation of our products will be implemented by the United States or other countries. Because sales of our products have been
denominated to date primarily in United States dollars, increases in the value of the United States dollar could increase the price of our products so that they become relatively more expensive to customers in the local currency of a particular
country, leading to a reduction in sales and profitability in that country. Future international activity may result in increased foreign currency denominated sales. Gains and losses on the conversion to United States dollars of accounts payable and
other monetary assets and liabilities arising from international operations may contribute to fluctuations in our results of operations.

Some of our customer purchase orders and agreements are governed by foreign laws, which may differ significantly from laws in the United States. As a result, our ability to enforce our rights under such
agreements may be limited compared with our ability to enforce our rights under agreements governed by laws in the United States.

*Our portfolio of short-term investments are exposed to certain market risks.

We maintain an investment portfolio of various holdings, types of instruments and maturities. These securities are recorded on our consolidated balance sheets at fair value with unrealized gains or losses
reported as a separate component of accumulated other



46

##### Table of Contents

comprehensive income (loss), net of tax. Our investment portfolio is exposed to market risks related to changes in interest rates and credit ratings of the issuers, as well as to the risks of
default by the issuers and lack of overall market liquidity. Substantially all of these securities are subject to interest rate and credit rating risk and will decline in value if interest rates increase or one of the issuers credit ratings is
reduced. Increases in interest rates or decreases in the credit worthiness of one or more of the issuers in our investment portfolio could have a material adverse impact on our financial condition or results of operations. During the fiscal
years ended March 31, 2010 and 2009, we recorded $4.1 million and $17.1 million respectively, in write-downs in the carrying value of certain securities as we determined the decline in the fair value of these securities to be
other-than-temporary. If there is a further deterioration in market conditions or there are additional losses incurred, we may be required to record a further decline in the carrying value of these securities resulting in further charges. At
December 31, 2010, the unrealized losses on these securities, that were not written down as an other-than-temporary impairment charge, were approximately $1.3 million. If the fair value of any of these securities does not recover to at least
the amortized cost of such security or we are unable to hold these securities until they recover, we may be required to record a decline in the carrying value of these securities.

Our restructuring activities could result in management distractions, operational disruptions and other difficulties.

Over the past several years, we have initiated several restructuring activities in an effort to reduce operating
costs, including new restructuring initiatives announced in October 2008, February 2009 and January 2010. Employees whose positions were eliminated in connection with these restructuring activities may seek employment with our customers or
competitors. Although each of our employees is required to sign a confidentiality agreement with us at the time of hire, we cannot guarantee that the confidential nature of our proprietary information will be maintained in the course of such future
employment. Any additional restructuring efforts could divert the attention of our management away from our operations, harm our reputation and increase our expenses. We cannot guarantee that we will not undertake additional restructuring
activities, that any of our restructuring efforts will be successful, or that we will be able to realize the cost savings and other anticipated benefits from our previous or future restructuring plans. In addition, if we continue to reduce our
workforce, it may adversely impact our ability to respond rapidly to new growth opportunities.

Our markets are subject
to rapid technological change, so our success depends heavily on our ability to develop and introduce new products.

The markets for our products are characterized by:



| |  |  | rapidly changing technologies;
| | - |  | ------------------------------



| |  |  | evolving and competing industry standards;
| | - |  | ------------------------------------------



| |  |  | changing customer needs;
| | - |  | ------------------------



| |  |  | frequent introductions of new products and enhancements;
| | - |  | --------------------------------------------------------



| |  |  | increased integration with other functions;
| | - |  | -------------------------------------------



| |  |  | long design and sales cycles;
| | - |  | -----------------------------



| |  |  | short product life cycles; and
| | - |  | ------------------------------



| |  |  | intense competition.
| | - |  | --------------------

To develop new products for the communications or other technology markets, we must develop, gain access to and use leading technologies in a cost-effective and timely manner and continue to develop
technical and design expertise. We must have our products designed into our customers future products and maintain close working relationships with key customers in order to develop new products that meet customers changing needs. We
must respond to changing industry standards, trends towards increased integration and other technological changes on a timely and cost-effective basis. Our pursuit of technological advances may require substantial time and expense and may ultimately
prove unsuccessful. If we are not successful in adopting such advances, we may be unable to timely bring to market new products and our revenues will suffer.

Many of our products are based on industry standards that are continually evolving. Our ability to compete in the future will depend on our ability to identify and ensure compliance with these evolving
industry standards. The emergence of new industry standards could render our products incompatible with products developed by major systems manufacturers. As a result, we could be required to invest significant time and effort and to incur
significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards or requirements, we could miss opportunities to achieve crucial design wins which in
turn could have a material adverse effect on our business, operating results and financial condition.

The markets in
which we compete are highly competitive, and we expect competition to increase in these markets in the future.

The
markets in which we compete are highly competitive, and we expect that domestic and international competition will increase in these markets, due in part to deregulation, rapid technological advances, price erosion, changing customer preferences and
evolving industry standards. Increased competition could result in significant price competition, reduced revenues, lower profit margins or loss of market share. Our ability to compete successfully in our markets depends on a number of factors,
including:



| |  |  | our ability to partner with OEM and channel partners who are successful in the market;
| | - |  | --------------------------------------------------------------------------------------



47

| |  |  | market acceptance of competitors products; and
| | - |  | -----------------------------------------------



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

Our competitors may offer enhancements to existing products, or offer new products based on new technologies, industry standards or customer requirements that are available to customers on a more timely
basis than comparable products from us or that have the potential to replace or provide lower cost alternatives to our products. The introduction of enhancements or new products by our competitors could render our existing and future products
obsolete or unmarketable. We expect that certain of our competitors and other semiconductor companies may seek to develop and introduce products that integrate the functions performed by our IC products on a single chip, thus eliminating the need
for our products. Each of these factors could have a material adverse effect on our business, financial condition and results of operations.

In the transport communications IC markets, we compete primarily against companies such as Broadcom, Cortina, Netlogic, PMC-Sierra and Vitesse. In the embedded processor communications IC market, we
compete with technology companies such as Freescale Semiconductor, Cavium and Intel. Many of these companies may have substantially greater financial, marketing and distribution resources than we have. Certain of our customers or potential customers
have internal IC design or manufacturing capabilities with which we compete. We may also face competition from new entrants to our target markets, including larger technology companies that may develop or acquire differentiating technology and then
apply their resources to our detriment. Any failure by us to compete successfully in these target markets would have a material adverse effect on our business, financial condition and results of operations.

Our operating results depend on manufacturing output and yields of our ICs and printed circuit board assemblies, which may not meet
expectations.

The yields on wafers we have manufactured decline whenever a substantial percentage of wafers must be
rejected or a significant number of die on each wafer are nonfunctional. Such declines can be caused by many factors, including minute levels of contaminants in the manufacturing environment, design issues, defects in masks used to print circuits on
a wafer and difficulties in the fabrication process. Design iterations and process changes by our suppliers can cause a risk of defects. Many of these problems are difficult to diagnose, are time consuming and expensive to remedy and can result in
shipment delays.

We estimate yields per wafer and final packaged parts in order to estimate the value of inventory. If yields
are materially different than projected, work-in-process inventory may need to be re-valued. We may have to take inventory write-downs as a result of decreases in manufacturing yields. We may suffer periodic yield problems in connection with new or
existing products or in connection with the commencement of production at a new manufacturing facility.

We must develop
or otherwise gain access to improved IC process technologies.

Our future success will depend upon our ability to
access new IC process technologies. In the future, we may be required to transition one or more of our IC products to process technologies with smaller geometries, other materials or higher speeds in order to reduce costs or improve product
performance. We may not be able to gain access to new process technologies in a timely or affordable manner or products based on these new technologies may not achieve market acceptance.

The complexity of our products may lead to errors, defects and bugs, which could
negatively impact our reputation with customers and result in liability.

Products as complex as ours may contain
errors, defects and bugs when first introduced or as new versions are released. Our products have in the past experienced such errors, defects and bugs. Delivery of products with production defects or reliability, quality or compatibility problems
could significantly delay or hinder market acceptance of the products or result in a costly recall and could damage our reputation and adversely affect our ability to retain existing customers and to attract new customers. Errors, defects or bugs
could cause problems with device functionality, resulting in interruptions, delays or cessation of sales to our customers.

We
may also be required to make significant expenditures of capital and resources to resolve such problems. We cannot assure you that problems will not be found in new products after commencement of commercial production, despite testing by us, our
suppliers or our customers. Any problem could result in:



| |  |  | additional development costs;
| | - |  | -----------------------------



| |  |  | loss of, or delays in, market acceptance;
| | - |  | -----------------------------------------



| |  |  | diversion of technical and other resources from our other development efforts;
| | - |  | ------------------------------------------------------------------------------



| |  |  | claims by our customers or others against us; and
| | - |  | -------------------------------------------------



| |  |  | loss of credibility with our current and prospective customers.
| | - |  | ---------------------------------------------------------------

Any such event could have a material adverse effect on our business, financial condition and results of operations.

If our internal control over financial reporting is not considered effective, our business and stock price could be adversely
affected.

Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate the effectiveness of our internal
control over financial reporting as of the end of each fiscal year, and to include a management report assessing the effectiveness of our internal control over financial reporting in our annual report on Form 10-K for that fiscal year.
Section 404 also requires our independent registered public accounting firm to attest to and report on the effectiveness of our internal control over financial reporting.

Our management, including our chief executive officer and chief financial officer, does not expect that our internal control over financial reporting will prevent all errors and all fraud. A control
system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control systems objectives will be met. Further, the design of a control system must reflect the fact that there are resource
constraints, and the benefits of control must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of internal control can provide absolute assurance that all control issues and instances
of fraud involving a company have been, or will be, detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its
stated goals under all potential future conditions. Over time, our internal control over financial reporting may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of
the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Our management has concluded, and our independent registered public accounting firm has attested, that our internal control over
financial reporting was effective as of March 31, 2010. We cannot assure you that we or our independent registered public accounting firm will not identify a material weakness in our internal control in the future. A material weakness in our
internal control over financial reporting would require management and our independent registered public accounting firm to report our internal control as ineffective. If our internal control over financial reporting is not considered effective, we
may experience a restatement like we have in the past of our financial statements and/or a loss of public confidence, either of which could have an adverse effect on our business and on the market price of our common stock.

*Our future success depends in part on the continued service of our key senior management, design engineering, sales, marketing,
and manufacturing personnel, our ability to identify, hire and retain additional, qualified personnel and successful succession planning.

Our future success depends to a significant extent upon the continued service of our senior management personnel and successful succession planning. The loss of key senior executives could have a material
adverse effect on our business. There is intense competition for qualified personnel in the semiconductor industry, in particular design, product and test engineers. We may not be able to continue to attract and retain engineers or other qualified
personnel necessary for the development of our business, or to replace engineers or other qualified personnel who may leave our employment in the future. We face the risks associated with our former employees assisting their new employers to recruit
our key talent, in violation of their non-solicitations covenants to us, as well as allegations by other companies that we have unlawfully solicited their employees to join us. There may be significant costs associated with recruiting, hiring and
retaining personnel. Periods of contraction in our business may inhibit our ability to attract and retain our personnel. Loss of the services of, or failure to recruit, key design engineers or other technical and management personnel could be
significantly detrimental to our product development or other aspects of our business.

To manage operations effectively, we will be required to continue to improve our
operational, financial and management systems and to successfully hire, train, motivate, and manage our employees. The integration of future acquisitions would require significant additional management, technical and administrative resources. We
cannot guarantee that we would be able to manage our expanded operations effectively.

Our ability to supply a
sufficient number of products to meet demand could be severely hampered by a shortage of water, electricity or other supplies, or by natural disasters or other catastrophes.

The manufacture of our products requires significant amounts of water. Previous droughts have resulted in restrictions being placed on
water use by manufacturers. In the event of a future drought, reductions in water use may be mandated generally and our external foundries ability to manufacture our products could be impaired.

Several of our facilities, including our principal executive offices, are located in California. California has experienced prolonged
energy alerts and blackouts caused by disruption in energy supplies. As a consequence, businesses and other energy consumers in California continue to experience substantially increased costs of electricity and natural gas. We are unsure whether
energy alerts and blackouts will reoccur or how severe they may become in the future. Many of our customers and suppliers are also headquartered or have substantial operations in California. If we or any of our major customers or suppliers located
in California experience a sustained disruption in energy supplies, our results of operations could be materially and adversely affected.

A significant portion of our manufacturing operations are located in Asia. These areas are subject to natural disasters such as earthquakes or floods. We do not have earthquake or business interruption
insurance for these facilities, because adequate coverage is not offered at economically justifiable rates. A significant natural disaster or other catastrophic event could have a material adverse impact on our business, financial condition and
operating results.

The effects of war, acts of terrorism or global threats, including, but not limited to, the outbreak of
epidemic disease, could have a material adverse effect on our business, operating results and financial condition. The continued threat of terrorism and heightened security and military action in response to this threat, or any future acts of
terrorism, may cause further disruptions to local and global economies and create further uncertainties. To the extent that such disruptions or uncertainties result in delays or cancellations of customer orders, or the manufacture or shipment of our
products, our business, operating results and financial condition could be materially and adversely affected.

We could
incur substantial fines or litigation costs associated with our storage, use and disposal of hazardous materials.

We
are subject to a variety of federal, state and local governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in our manufacturing process. Any failure to comply with
present or future regulations could result in the imposition of fines, the suspension of production or a cessation of operations. These regulations could require us to acquire costly equipment or incur other significant expenses to comply with
environmental regulations or clean up prior discharges. Since 1993, we have been named as a PRP along with more than 100 other companies that used Omega Chemical Corporation waste treatment facility in Whittier, California. The U.S. Environmental
Protection Agency (EPA) has alleged that Omega failed to properly treat and dispose of certain hazardous waste material. We are a member of a large group of PRPs that has agreed to fund certain on-going remediation efforts at the Omega
Chemical Corporation site. To date, our payment obligations with respect to these funding efforts have not been material, and although we believe that our future obligations to fund these efforts will not have a material adverse effect on our
business, financial condition or operating results, we cannot guarantee this result. In 2007, the PRPs were sued by a downstream chemical company; that action has been stayed since March 2008 to allow for further delineation of the regional
groundwater. In 2009, the U.S. Supreme Court decided U.S. v. Burlington Northern & Santa Fe Railway Co., 129 S.Ct. 1870, which determined that hazardous substance cleanup liability need not be joint and several in all cases. As a
result of this decision, the liability is potentially divisible among the PRP at an earlier stage in superfund cases such as Omega. At this point we do not know and can not predict the full impact of this decision on our liability, however, to
protect against an unfavorable impact, we have joined the recently formed Omega Allocation Committee in order to limit such exposure. Although we believe that we have been and currently are in material compliance with applicable environmental laws
and regulations, we cannot guarantee that we are or will be in material compliance with these laws or regulations or that our future obligations to fund any remediation efforts, including those at the Omega Chemical Corporation site, will not have a
material adverse effect on our business.

Environmental laws and regulations could cause a disruption in our business
and operations.

We are subject to various state, federal and international laws and regulations governing the
environment, including those restricting the presence of certain substances in electronic products and making manufacturers of those products financially responsible for the collection, treatment, recycling and disposal of certain products. Such
laws and regulations have been passed in several jurisdictions in which we operate, including various European Union (EU) member countries. For example, the EU has



50



---

##### Table of Contents

enacted the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) and the Waste Electrical and Electronic Equipment (WEEE)
directives. RoHS prohibits the use of lead and other substances in semiconductors and other products put on the market after July 1, 2006. The WEEE directive obligates parties that place electrical and electronic equipment on the market in the
EU to put a clearly identifiable mark on the equipment, register with and report to EU member countries regarding distribution of the equipment, and provide a mechanism to take back and properly dispose of the equipment. There can be no assurance
that similar programs will not be implemented in other jurisdictions resulting in additional costs, possible delays in delivering products, and even the discontinuance of existing and planned future product replacements if the cost were to become
prohibitive.

Any dispositions we make could disrupt our business and harm our results of operations and financial
condition.

We may dispose of assets or businesses that represent a significant portion of our business. We completed
the sale of our 3ware storage adapter business, a significant portion of our storage business, to LSI Corporation on April 21, 2009. As a result, we now expect to generate all of our sales from our remaining business, which we would be required
to grow in order to achieve profitability. Economic and other factors may prevent us from growing our remaining business. If we fail to grow our remaining business, it could have a material adverse impact on our business, financial condition and
operating results. Future dispositions may involve numerous risks, including:



| |  |  | problems carving out or disposing of assets, operations, technologies and products;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the disposal of such assets or businesses could have an unanticipated adverse effect on the remaining business;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | unanticipated costs;
| | - |  | --------------------



| |  |  | diversion of managements attention from core ongoing operations;
| | - |  | -----------------------------------------------------------------



| |  |  | potential adverse effects on existing business relationships with suppliers and customers; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | if we do not structure the disposition properly and scale expenses according to the size of the remaining business, we could continue to incur expenses
that could be unsustainable given the scope of the remaining business.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We may not be able to protect
our intellectual property adequately.

We rely in part on patents to protect our intellectual property. We cannot
assure you that our pending patent applications or any future applications will be approved, or that any issued patents will adequately protect the intellectual property in our products and processes, will provide us with competitive advantages or
will not be challenged by third parties, or that if challenged, any such patent will be found to be valid or enforceable. Others may independently develop similar products or processes, duplicate our products or processes or design around any
patents that may be issued to us.

To protect our intellectual property, we also rely on the combination of mask work
protection under the Federal Semiconductor Chip Protection Act of 1984, trademarks, copyrights, trade secret laws, employee and third-party nondisclosure agreements, and licensing arrangements. Despite these efforts, we cannot assure you that others
will not independently develop substantially equivalent intellectual property or otherwise gain access to our trade secrets or intellectual property, or disclose such intellectual property or trade secrets, or that we can meaningfully protect our
intellectual property. A failure by us to meaningfully protect our intellectual property could have a material adverse effect on our business, financial condition and operating results.

We generally enter into confidentiality agreements with our employees, consultants and strategic partners. We also try to control access
to and distribution of our technologies, documentation and other proprietary information. Despite these efforts, parties may attempt to copy, disclose, obtain or use our products, services or technology without our authorization. Also, former
employees may seek employment with our business partners, customers or competitors and we cannot assure you that the confidential nature of our proprietary information will be maintained in the course of such future employment. Additionally, former
employees or third parties could attempt to penetrate our network to misappropriate our proprietary information or interrupt our business. Because the techniques used by computer hackers to access or sabotage networks change frequently and generally
are not recognized until launched against a target, we may be unable to anticipate these techniques. As a result, our technologies and processes may be misappropriated, particularly in foreign countries where laws may not protect our proprietary
rights as fully as in the United States.

*We could be harmed by litigation involving patents, proprietary rights or
other claims.

Litigation may be necessary to enforce our intellectual property rights, to determine the validity and
scope of the proprietary rights of others or to defend against claims of infringement or misappropriation. The semiconductor industry is characterized by substantial litigation regarding patent and other intellectual property rights. Such litigation
could result in substantial costs and diversion of resources, including the attention of our management and technical personnel, and could have a material adverse effect on our business, financial condition and results of operations. We may be
accused of infringing on the intellectual property rights of third parties. We have certain indemnification obligations to customers with respect to the infringement of third-party intellectual property



51



---

##### Table of Contents

rights by our products. We cannot assure you that infringement claims by third parties or claims for indemnification by customers or end users resulting from infringement claims will not be
asserted in the future, or that such assertions will not harm our business.

Any litigation relating to the intellectual
property rights of third parties would at a minimum be costly and could divert the efforts and attention of our management and technical personnel. In the event of any adverse ruling in any such litigation, we could be required to pay substantial
damages, cease the manufacturing, use and sale of infringing products, discontinue the use of certain processes or obtain a license under the intellectual property rights of the third party claiming infringement. A license might not be available on
reasonable terms or at all.

From time to time, we may be involved in litigation relating to other claims arising out of our
operations in the normal course of business. For example, we were recently served a complaint by Nortel Networks, Inc. in connection with its bankruptcy proceedings alleging that approximately $548,000 of payments that we previously received from
Nortel were preferential and that the transfer of such funds to us is subject to avoidance and recovery by Nortel. The ultimate outcome of any such litigation matters, including the Nortel bankruptcy matter, could have a material, adverse effect on
our business, financial condition or operating results.

Our stock price is volatile.

The market price of our common stock has fluctuated significantly. In the future, the market price of our common stock could be subject to
significant fluctuations due to general economic and market conditions and in response to quarter-to-quarter variations in:



| |  |  | our anticipated or actual operating results;
| | - |  | --------------------------------------------



| |  |  | announcements or introductions of new products by us or our competitors;
| | - |  | ------------------------------------------------------------------------



| |  |  | anticipated or actual operating results of our customers, peers or competitors;
| | - |  | -------------------------------------------------------------------------------



| |  |  | technological innovations or setbacks by us or our competitors;
| | - |  | ---------------------------------------------------------------



| |  |  | conditions in the semiconductor, communications or information technology markets;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | the commencement or outcome of litigation or governmental investigations;
| | - |  | -------------------------------------------------------------------------



| |  |  | changes in ratings and estimates of our performance by securities analysts;
| | - |  | ---------------------------------------------------------------------------



| |  |  | announcements of merger or acquisition transactions;
| | - |  | ----------------------------------------------------



| |  |  | management changes;
| | - |  | -------------------



| |  |  | our inclusion in certain stock indices; and
| | - |  | -------------------------------------------



| |  |  | other events or factors.
| | - |  | ------------------------

The stock market in recent years has experienced extreme price and volume fluctuations that have affected the market prices of many high technology companies, particularly semiconductor companies. In some
instances, these fluctuations appear to have been unrelated or disproportionate to the operating performance of the affected companies. Any such fluctuation could harm the market price of our common stock. In addition, the current decline of the
financial markets and related factors beyond our control, including the credit and mortgage crisis in both the U.S. and worldwide, may cause our stock price to decline rapidly and unexpectedly.

The anti-takeover provisions of our certificate of incorporation and of the Delaware general corporation law may delay, defer or
prevent a change of control.

Our board of directors has the authority to issue up to 2.0 million shares of
preferred stock and to determine the price, rights, preferences and privileges and restrictions, including voting rights, of those shares without any further vote or action by our stockholders. The rights of the holders of common stock will be
subject to, and may be harmed by, the rights of the holders of any shares of preferred stock that may be issued in the future. The issuance of preferred stock may delay, defer or prevent a change in control, as the terms of the preferred stock that
might be issued could potentially prohibit our consummation of any merger, reorganization, sale of substantially all of our assets, liquidation or other extraordinary corporate transaction without the approval of the holders of the outstanding
shares of preferred stock. The issuance of preferred stock could have a dilutive effect on our stockholders.

If we
issue additional shares of stock in the future, it may have a dilutive effect on our stockholders.

We have a
significant number of authorized and unissued shares of our common stock available. These shares will provide us with the flexibility to issue our common stock for proper corporate purposes, which may include making acquisitions through the use of
stock, adopting additional equity incentive plans and raising equity capital. Any issuance of our common stock may result in immediate dilution of our stockholders.

On
October 27, 2010, the Board of Directors of the Company approved an amendment to the Companys Bylaws, to be effective November 3, 2010, that includes a new Section 8.13 which provides that unless the corporation consents in
writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the corporation, (ii) any action
asserting a claim for breach of a fiduciary duty owed by any director, officer or other employee of the corporation to the corporation or the corporations stockholders, (iii) any action asserting a claim arising pursuant to any provision
of the General Corporation Law of Delaware or the corporations certificate of incorporation or Bylaws, or (iv) any action asserting a claim governed by the internal affairs doctrine.
