NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)



1. Organization and Basis of Presentation



Organization Atheros Communications, Inc. (the Company) was
incorporated in May 1998 in the state of Delaware and commenced operations in December 1998. The Company is a developer of semiconductor system solutions for wireless communications products.



Basis of Presentation and Use of Estimates  The accompanying unaudited
Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP) related to interim financial statements based on applicable Securities
and Exchange Commission (the SEC) rules and regulations. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements. This financial information reflects all adjustments,
which are, in the opinion of the Company, of a normal and recurring nature and necessary to present fairly the statements of financial position, results of operations and cash flows for the dates and periods presented. The December 31, 2003 balance
sheet was derived from audited financial statements as of that date. All significant intercompany transactions and balances have been eliminated.



The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts
of assets, liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results may differ from these estimates.



These Condensed Consolidated Financial Statements should be read in
conjunction with the Companys audited consolidated financial statements for the fiscal year ended December 31, 2003 included in its Form S-1, as filed on February 11, 2004 with the SEC. The results of operations for the three and nine months
ended September 30, 2004 are not necessarily indicative of the results to be expected for any future periods.



2. Stockholders Equity



On January 23, 2004, the Company completed a 3-for-4 reverse split of its outstanding common stock. All information related to common stock, options and warrants to purchase common stock and earnings per share included in the accompanying
condensed consolidated financial statements have been adjusted to give effect to the reverse stock split.



In February 2004, the Company completed an initial public offering whereby it sold 10,350,000 shares of common stock (including underwriters
overallotment) and received net proceeds of $133.2 million (after underwriters discount and related offering expenses). Upon the closing of the initial public offering, all outstanding shares of the Companys convertible preferred stock
converted into 22,532,670 shares of common stock.



On February
26, 2004, the Company filed a Form S-8 to register its stock option plans with the SEC. The Company registered 750,000 shares for its 2004 Employee Stock Purchase Plan (ESPP), 2,553,830 shares for its 2004 Stock Incentive Plan and
8,694,098 outstanding options under its 1998 Stock Incentive Plan. The ESPP allows qualified employees to purchase shares at a 15% discount from a price pre-determined by the market value of the stock at the beginning and ending of the offering
period, which occurs twice yearly. In May 2004, 42,879 shares were issued under the ESPP. The 2004 Stock Incentive Plan shares will be used to grant non-qualified stock options to employees and consultants of the Company as the management and board
of directors determine. The outstanding options under the 1998 Stock Incentive Plan represent existing option grants to employees and consultants of the Company.

3. Significant Accounting Policies



The Companys significant accounting policies are disclosed in its
audited consolidated financial statements for the year ended December 31, 2003 included in the Companys Form S-1 filed with the SEC on February 11, 2004. The Companys significant accounting policies have not changed during the nine
months ended September 30, 2004.



Stock-Based Compensation  The
Company accounts for stock-based compensation to employees in accordance with the provisions of Accounting Principles Board Opinion (APB) No. 25, Accounting for Stock Issued to Employees, and complies with the disclosure
provisions of Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based Compensation, as amended by SFAS No. 148, Accounting for Stock-Based Compensation  Transition and Disclosures. The
Company accounts for equity instruments issued to nonemployees in accordance with the provisions of SFAS No. 123 and Emerging Issues Task Force (EITF) No. 96-18, Accounting for Equity Instruments That Are Issued to Other Than
Employees for Acquiring, or in Connection with Selling, Goods or Services, which requires that the fair value of such instruments be recognized as an expense over the period in which the related services are provided. Such expenses are
measured using the value of the equity instruments issued, as this is more readily determinable than the fair value of the services received.



The Company amortizes deferred stock-based compensation using the graded vesting method over the vesting periods of the stock options, generally four to
five years. The graded vesting method provides for vesting of portions of the overall awards at interim dates and results in accelerated vesting as compared to the straight-line method. Had compensation expense been determined based on the fair
value at the grant date for all employee awards, consistent with the provisions of SFAS No. 123, the Companys pro forma net income or loss and net income or loss per share would have been as follows (in thousands, except per share data):

Through November 26,
2003, the date of the Companys initial filing with the SEC related to its initial public offering, the Company used the minimum value method to estimate the fair value of options granted to employees. Options granted subsequent to November 26,
2003 were valued using the Black-Scholes valuation model. The fair value of the Companys stock-based awards to employees was estimated using the following weighted-average assumptions:

Because the
Companys common stock has recently become publicly traded, its historical data on the volatility of its common stock is limited. Therefore, the Company estimates volatility based on the average volatilities of similar entities.

Product Warranty  The Company generally provides a warranty on its products for
a period of one year, however, it may be greater for certain customers. Accordingly, the Company provides for the warranty costs at the time of sale based on historical activity. The determination of such provisions requires the Company to make
estimates of product return rates and expected costs to repair or replace the products under warranty. If the actual return rates and/or repair and replacement costs differ significantly from these estimates, adjustments to cost of sales may be
required in future periods. Components of the accrual for warranty costs are as follows (in thousands):

6. Short and Long-Term Debt



Bank Loan and Security Agreement



In March 2003, the Company entered into a loan agreement
with a bank, which was amended in December 2003 (the Agreement). The Agreement allows the Company to finance up to $10,000,000 of working capital requirements (subject to certain limitations) and $2,000,000 of equipment purchases.
Borrowings under the Agreement are secured by all of the tangible assets of the Company. The Agreement contains financial covenants related to tangible net worth, as well as other non-financial covenants. As of September 30, 2004, the Company was in
compliance with all required covenants. Interest on borrowings under the working capital line is payable monthly and is calculated at the banks prime rate (4.75% at September 30, 2004) plus 1.0%. Borrowings under the working capital line are
due in March 2005, or earlier as required by borrowing limits defined in the Agreement. Principal and interest is payable monthly for borrowings related to equipment purchases.



As of December 31, 2003, $4,000,000 and $1,837,000 was outstanding under the working capital and equipment purchase
arrangements, respectively. In February 2004, the Company repaid these balances in full and no balances were outstanding at September 30, 2004. The Company had $10,000,000 available for borrowing under the working capital arrangement and no further
funds available for borrowing under the equipment purchase arrangement at September 30, 2004.

9. Recent Accounting Pronouncements



In March 2004, the Financial Accounting Standards Board (FASB) reached a consensus on EITF Issue No. 03-1, The Meaning of
Other-Than-Temporary Impairment and Its Application to Certain Investments, which provides new guidance for assessing impairment losses on investments. Additionally, EITF 03-1 includes new disclosure requirements for investments that are deemed
to be temporarily impaired. In September 2004, the FASB delayed the accounting provisions of EITF 03-1; however the disclosure requirements remain effective for annual periods ending after June 15, 2004. The Company will evaluate the impact of EITF
03-1 once final guidance is issued.

Overview



We are a leading developer of
semiconductor system solutions for wireless communications products. We combine our wireless systems expertise with high-performance radio frequency, or RF, mixed signal and digital semiconductor design skills to provide highly integrated chipsets
that are manufacturable on low-cost, standard complementary metal-oxide semiconductor, or CMOS, processes. We were incorporated in May 1998 and commenced operations in December 1998. Through December 31, 2000, we were engaged principally in research
and development. We first generated meaningful revenue from sales of our products in the fourth quarter of 2001. Our revenue from 2001 through the first half of 2002 was characterized by relatively low volumes, high average selling prices and high
gross margins. Beginning in the second half of 2002 through the quarter ended June 30, 2004, our revenue was characterized by increasing volumes and decreasing average selling prices for our chipsets. During the quarter ended September 30, 2004, we
experienced a decrease in volume and continued decreases in average selling prices of our chipsets. Although our results for the first three quarters of 2004 were profitable, we experienced net losses in all others periods from inception through
December 31, 2003. Through September 30, 2004, we had an accumulated deficit of $75.9 million.



Our product portfolio is currently comprised of various generations of our radio-on-a-chip, media access controller+baseband and wireless system-on-a-chip products supporting the Institute of Electrical and
Electronics Engineers, or IEEE, family of wireless local area networking, or WLAN, standards, including the 802.11b, 802.11g and 802.11a standards. These products are typically sold together as chipsets as part of a wireless system solution that
also incorporates software and system-level reference designs. Our wireless systems solutions are used in a variety of applications in the personal computer, enterprise access, small office and branch office networking, home networking, hotspot and
consumer electronics markets.



Net Revenue. Our revenue
is derived primarily from the sale of WLAN chipset products and, to a lesser extent, from licensed software and services. Since our inception, we have not recognized revenue related to non-recurring engineering arrangements. Our sales have
historically been made on the basis of purchase orders rather than long-term agreements. Original equipment manufacturers, or OEMs, utilize our chipsets in developing their wireless system solutions such as access point, cardbus and integrated
client card products. Some OEMs directly purchase chipsets from us and manufacture their products. Other OEMs utilize original design manufacturers, or ODMs, to design and build subsystem products that the OEM then purchases from the ODM and
incorporates into the OEMs wireless system solution. Accordingly, we ship our products either directly to the OEM or to the ODM based on the requirements of each OEM. Purchase orders are received from an OEM or an ODM and we generally
recognize revenue based on the shipment of chipsets to this customer. A single ODM may provide products based on our chipsets to numerous OEMs. However, we attempt to maintain a close relationship with the target OEM to monitor end-market demand.
Due to the use of ODMs, our direct customer base is relatively concentrated, although we believe that the number of total OEMs who purchase our chipsets through ODMs is broader. We anticipate that we may continue to experience changes in our ODM
customer base as our end customers change ODMs for a variety of reasons while still using our chipsets.



During the quarter ended September 30, 2004, shipment volumes of our first single chip wireless solution integrating the radio, media access controller
and baseband onto one chip increased as a percentage of total shipments. This single chip solution is generally priced lower than the combined average selling prices of our multi-chip solutions. Therefore, we expect our average selling price per
chipset to continue to decline as our single chip volume increases.

In the nine months ended September 30, 2004, Hon-Hai Precision Industry (formerly Ambit Microsystems),
Askey Computer Corporation and Global Sun Technology, Inc. accounted for 26%, 16% and 12% of our net revenue, respectively. In the nine months ended September 30, 2003, Global Sun Technology and Hon-Hai accounted for 28% and 19% of our net revenue,
respectively. We expect to continue to have major concentrations of sales to a relatively small list of ODM customers.



Substantially all of our sales are to customers outside the United States and Canada. Sales to customers in Asia accounted for 98% of net revenue for each
of the nine month periods ending September 30, 2004 and 2003. Because many of our ODM customers are located in Asia, we anticipate that a majority of our revenue will continue to be represented by sales to customers in that region. Although a large
percentage of our sales are made to customers in Asia, we believe that a significant number of the systems designed by these customers are then sold through to OEMs outside of Asia. All of our sales are denominated in United States dollars.



Cost of Goods Sold. Cost of goods sold relates
primarily to the purchase of silicon wafers, costs associated with assembly, test and inbound and outbound shipping of our chipsets, costs of personnel, materials and occupancy associated with manufacturing support and quality assurance, royalty
costs and adjustments to state inventories at the lower of cost or market caused by transitions from older to newer products. Additionally, our cost of goods sold includes accruals for warranty obligations, which we record when revenue is
recognized. Because we do not have long-term, fixed supply agreements, our wafer costs are subject to changes based on the cyclical demand for semiconductors. In addition, after we purchase wafers from foundries, we are subject to yield risk related
to manufacturing these wafers into die. We expect that our cost of goods sold will increase as a percentage of revenue due to volume pricing pressures and changing product mix, resulting in decreased gross margins.



Research and Development. Research and development expense relates
primarily to compensation and associated costs related to development employees and contractors, mask and reticle costs, prototype wafers, software and computer-aided design software licenses, intellectual property license costs, reference design
development costs, development testing and evaluation, occupancy costs and depreciation expense. All research and development costs are expensed as incurred. We expect our research and development costs to increase in absolute dollars as we invest
to develop new products to be competitive in the future.



Sales and Marketing. Sales and marketing expense relates primarily to compensation and associated costs for marketing and selling personnel, sales commissions to independent sales representatives, public relations, promotional and
other marketing expenses, travel, trade show expenses, depreciation expenses and occupancy costs. We expect sales and marketing expenses will increase in absolute dollars as we hire additional personnel, expand our sales and marketing efforts and
pay increased sales commissions.



General and
Administrative. General and administrative expense relates primarily to compensation and associated costs for general and administrative personnel, professional and banking fees and occupancy costs. We expect that general and administrative
expense will increase in absolute dollars as we hire additional personnel and incur costs related to the anticipated growth of our business, our operation as a public company and improvements to our information technology infrastructure.



Stock-Based Compensation. In connection with the grant of stock
options in 2001, 2002 and 2003, we have recorded an aggregate of $6.5 million in stock-based compensation through September 30, 2004. These options are considered compensatory because the fair market value of our stock determined for financial
reporting purposes is greater than the fair value determined by the board of directors on the date of the grant or issuance. As of September 30, 2004, we had an aggregate of $3.2 million in stock-based compensation remaining to be amortized. We are
amortizing deferred stock-based compensation over the vesting period of the related option and warrant, which is generally four to five years using the graded vesting method. This deferred stock-based compensation balance will be amortized as
follows, assuming no forfeiture of awards: $661,000 during the fiscal fourth quarter of 2004; $1.6 million during 2005; $742,000 during 2006; $203,000 during 2007; and $12,000 during 2008.



Interest Income, Net.Interest income consists of interest earned on
cash and cash equivalents and marketable securities balances. Interest expense consists of interest on our revolving line of credit, equipment loans and equipment lease.



Provision for Income Taxes. Provision for income tax relates primarily to federal, state and foreign taxes on our
income.



Critical Accounting Policies and Estimates



Our discussion and analysis of our financial condition and the results of
operations are based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and
judgments that affect the reported amounts of assets, liabilities, revenue and expenses. We base our estimates on historical experience and on various other assumptions 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. Actual results may differ from these estimates under different assumptions or conditions. Our critical
accounting policies are set forth below.

##### Table of Contents

Revenue Recognition. We derive revenue primarily from three sources:



| |  | the sale of our wireless chipsets and reference designs;
| | - | --------------------------------------------------------



| |  | our licensed software and technical documentation; and
| | - | ------------------------------------------------------



| |  | service and support revenue relating to the licensed software.
| | - | --------------------------------------------------------------



We recognize revenue in accordance with SEC Staff Accounting Bulletin (SAB) No. 104, Revenue Recognition. SAB 104 requires that four
basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is fixed and determinable; and (4) collectibility is reasonably
assured. Determination of criteria (3) and (4) are based on managements judgment regarding the fixed nature of the fee charged for the products delivered and the collectibility of those fees. Should changes in conditions cause management to
determine these criteria are not met for certain future transactions, revenue recognized for any reporting period could be adversely impacted.



We provide customer incentives to some of our direct and indirect customers. These payments are recorded as a reduction of revenue at the time at which we
ship product to the customers in accordance with Emerging Issues Task Force Issue No. 01-09, Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendors Products). Estimated incentive amounts
are recorded as a reduction of revenue and are based on agreements between the company and our customers. These estimates may require revisions at later dates if the actual sales data submitted by the customers differs significantly from the
original estimates.



Inventory. We continually assess
the recoverability of our inventory based on assumptions about demand and market conditions. Forecasted demand is determined based on historical sales and expected future sales. We value our inventories at the lower of actual cost (using the
first-in, first-out method) or its current estimated market value. We adjust our inventory to the estimated lower of cost or market value to account for its obsolescence or lack of marketability. Adjustments are calculated as the difference between
the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be
required that may adversely affect our operating results. If actual market conditions are more favorable, we may have higher gross margins when products are sold.



Stock Options. We have elected to follow the intrinsic value-based method prescribed by Accounting Principles Board
Opinion (APB) No. 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for employee stock options rather than adopting the alternative fair value accounting provided under Statement of
Financial Accounting Standards (SFAS) No. 123, Accounting for Stock Based Compensation. Therefore, we do not record any compensation expense for stock options we grant to our employees where the exercise price equals the fair
market value of the stock on the date of grant and the exercise price, number of shares eligible for issuance under the options and vesting period are fixed. We comply with the disclosure requirements of SFAS No. 123 and SFAS No. 148, which require
that we disclose our pro forma net income or loss and net income or loss per common share as if we had expensed the fair value of the options. In calculating such fair value, there are certain assumptions that we use, as disclosed in note 3 of our
unaudited condensed consolidated financial statements.



Accounts Receivable Allowance. We perform ongoing credit evaluations of our customers and adjust credit limits and their credit worthiness, as determined by our review of current credit information. We continuously monitor
collections and payments from our customers and maintain an allowance for doubtful accounts based upon our historical experience, our anticipation of uncollectible accounts receivable and any specific customer collection issues that we have
identified. While our credit losses have historically been within our expectations and the allowance established, we might not continue to experience the same credit loss rates that we have in the past. Our receivables are concentrated in a
relatively few number of customers. Although most of our receivables from inception through 2003 have been backed by letters of credit, substantially all of our major customers have converted or are expected to convert to open credit terms during
2004. Therefore, a significant change in the liquidity or financial position of any one customer could make collection of our accounts receivable more difficult, require us to increase our allowance for doubtful accounts and negatively affect our
working capital.



Product Warranty Accrual.We provide
for the estimated cost of product warranties at the time revenue is recognized. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our chipset suppliers, our warranty
obligation is affected by product failure rates, the cost of replacement chipsets and inbound and outbound freight costs incurred in replacing a chipset after failure. We continuously monitor chipset returns for warranty and maintain an accrual for
the related warranty expenses based on historical experience of similar products as well as various other assumptions that we believe to be reasonable under the circumstances. Should actual failure rates, cost of chipset replacement and inbound and
outbound freight costs differ from our estimates, revisions to the estimated warranty accrual would be required.

Comparison of Three
Months Ended September 30, 2004 to Three Months Ended September 30, 2003



Net Revenue. Net revenue for the three months ended September 30, 2004 was $38.3 million compared to $25.2 million for the comparable period of 2003, an increase of $13.1 million, or 52%. This increase in net
revenue is due to the increased acceptance of our wireless chipset products, an increase in the number of Personal Computer Original Equipment Manufacturer (PC OEM) and networking manufacturer design wins, the broadening of our product
line to provide integrated 802.11b, 802.11g and 802.11a products and the introduction of our single chip solution, integrating the radio, media access controller and baseband. As a result, the total number of chipsets shipped increased from
approximately 1.5 million in the third quarter of 2003 to approximately 3.6 million for the comparable period in 2004.



Gross Profit. Gross profit for the three months ended September 30, 2004 was $17.5 million compared to $10.2 million for the three months ended
September 30, 2003, an increase of $7.3 million, or 71%. In 2003 and the first three quarters of 2004, we focused on addressing higher volume markets, including the market for 802.11g and multi-mode products. We believe that the market for these
products, as well as our market share, has increased during these periods. This resulted in increased chipset volumes of approximately 135% and increased absolute gross profit dollars from the third quarter of 2003 to the same period in 2004. Gross
profit as a percentage of revenue increased to 45.6% for the three months ended September 30, 2004 compared to 40.5% in the comparable period of 2003. This increase resulted from a decrease in per unit costs related to design efficiencies and volume
purchasing discounts in the three months ended September 30, 2004, partially offset by a 35% decrease in average selling price. During the third quarter of 2004 and 2003, software license fee revenue contributed 0.6% and 1.7%, respectively, to our
gross margin.



Research and Development. Research and
development expense was $10.4 million for the three months ended September 30, 2004, or 27% of net revenue, compared to $7.5 million for the three months ended September 30, 2003, or 30% of net revenue. The $2.9 million increase in absolute dollars
was primarily due to increased compensation costs of $2.0 million to support a 56% increase in the number of research and development personnel. Additionally, consulting, prototype costs, mask sets and reticles, and equipment expenses increased
$902,000 in the three months ended September 30, 2004 over the same period in 2003, primarily resulting from increased chip development efforts in the three months ended September 30, 2004 as compared to the same period of 2003.



Sales and Marketing. Sales and marketing expense was $3.8 million for
the three months ended September 30, 2004, or 10% of net revenue, compared to $3.1 million for the three months ended September 30, 2003, or 13% of net revenue. The $690,000 increase in absolute dollars was primarily due to an increase in
compensation costs of $458,000 related to a 39% increase in the number of sales and marketing personnel from the third quarter of 2003 to the same period in 2004, and an increase in trade show and other marketing costs of $205,000 during the three
months ended September 30, 2004 as compared to the same period of 2003.

##### Table of Contents

General and Administrative. General and administrative expense increased to $2.1 million, or 6% of
net revenue, for the three months ended September 30, 2004, from $1.5 million, or 6% of revenue, for the three months ended September 30, 2003. The $613,000 increase in absolute dollars was primarily due to increased compensation costs of $351,000,
resulting from a 77% increase in the number of general and administrative personnel from September 30, 2003 to September 30, 2004. Additionally, as a result of becoming a public company in February 2004, our insurance and filing fee expenses
increased $200,000 during the three months ended September 30, 2004 over the same period in 2003.



Stock-Based Compensation. Stock-based compensation was $918,000 and $608,000 for the three months ended September 30, 2004 and 2003, respectively.



Interest Income, Net. Interest income, net was $658,000
for the three months ended September 30, 2004 compared to interest expense of $52,000 for the comparable period in 2003. During 2004, we experienced a higher amount of interest income from our investment balances which increased after the completion
of our initial public offering in February 2004. Our initial public offering provided us with $133.2 million in net proceeds. Interest expense was lower in the third quarter of 2004 than the same period in 2003, since in February 2004, we used $5.8
million of the proceeds from the initial public offering to repay in full balances outstanding under our loan agreement.



Provision for Income Taxes. Provision for income taxes was $68,000 for the three months ended September 30, 2004, and our effective tax rate was
8.1%, which reflects the utilization of net operating loss carryforwards. Provision for income taxes was $33,000 for the three months ended September 30, 2003, which related to taxes on foreign income.



Comparison of Nine Months Ended September 30, 2004 to Nine Months Ended
September 30, 2003



Net Revenue. Net
revenue for the nine months ended September 30, 2004 was $128.0 million compared to $49.7 million for the comparable period of 2003, an increase of $78.3 million, or 157%. This increase is due to the increased acceptance of our wireless chipset
products, an increase in the number of PC OEM and networking manufacturer design wins and the broadening of our product line to provide integrated 802.11b, 802.11g and 802.11a products. As a result, the total number of chipsets shipped increased
from approximately 2.9 million in the first nine months of 2003 to approximately 10.7 million for the comparable period in 2004.



Gross Profit. Gross profit for the nine months ended September 30, 2004 was $59.7 million compared to $20.5 million for the nine months ended
September 30, 2003, an increase of $39.2 million, or 191%. In 2003 and the first nine months of 2004, we focused on addressing higher volume markets, including the market for 802.11g and multi-mode products as this market rapidly expanded. This
resulted in increased chipset volumes of approximately 274% from the first nine months of 2003 to the same period of 2004 and increased absolute gross profit dollars from period to period. Gross profit as a percentage of revenue increased to 46.7%
for the nine months ended September 30, 2004 compared to 41.3% in the comparable period of 2003. This increase resulted from a decrease in per unit costs related to design efficiencies and volume purchasing discounts in the first nine months of
2004, partially offset by a 31% decrease in average selling prices. During the first nine months of 2004 and 2003, software license fee revenue contributed 0.6% and 2.5%, respectively, to our gross margin.



Research and Development. Research and development expense was $30.6
million for the first nine months of 2004, or 24% of net revenue, compared to $20.4 million for the nine months ended September 30, 2003, or 41% of net revenue. The $10.2 million increase in absolute dollars was primarily due to an increase in
compensation and travel costs of $6.3 million and software development license fees of $619,000 resulting from a 56% increase in the number of research and development personnel from September 30, 2003 to September 30, 2004. Additionally, licensing
costs related to intellectual property, consulting and outside services costs, equipment expense and prototype costs increased $2.8 million in the nine months ended September 30, 2004 over the same period in 2003, primarily resulting from the
increased chip development efforts in the nine months ended September 30, 2004 as compared to the same period of 2003.



Sales and Marketing. Sales and marketing expense was $11.5 million for the nine months ended September 30, 2004, or 9% of net revenue, compared to
$7.8 million for the nine months ended September 30, 2003, or 16% of net revenue. The $3.7 million increase in absolute dollars was primarily due to an increase in compensation and travel costs of $2.4 million related to a 39% increase in the number
of sales and marketing personnel from September 30, 2003 to September 30, 2004, an increase in sales commissions to third-party sales representatives of $399,000 related to a 157% increase in revenues for the first nine months of 2004 compared to
the same period of 2003 and an increase in trade show and other marketing expenses of $498,000 related to increased activities for new product introduction.



General and Administrative. General and administrative expense increased to $6.4 million, or 5% of net revenue, for the nine months ended September
30, 2004, from $3.7 million, or 7% of revenue, for the nine months ended September 30, 2003. The $2.7 million increase in absolute dollars was primarily due to additional compensation and travel costs of $1.1 million, resulting from a 77% increase
in the number of general and administrative personnel from September 30, 2003 to September 30, 2004. Additionally,

professional and consulting fees increased $490,000 for the nine months ended September 30, 2004 over the same period in
2003 resulting from increased legal fees related to patent filings, increased audit, tax and investor relations fees related to our becoming a public company in February 2004, and increased consulting fees related to upgrading our enterprise
resource planning and finance systems. Also as a result of becoming a public company in February 2004, our insurance and filing fee expenses increased $623,000 for the nine months ended September 30, 2004 over the same period of 2003. Finally, our
banking fees, consisting primarily of fees for processing letters of credit from our customers, increased $175,000 in the nine months ended September 30, 2004 over the same period in 2003.



Stock-Based Compensation. Stock-based compensation was $3.1 million
and $1.5 million for the nine months ended September 30, 2004 and 2003, respectively.



Interest Income, Net. Interest income, net was $1.3 million for the nine months ended September 30, 2004 compared to interest expense of $39,000 for the comparable period in 2003. During 2004, we experienced a
higher amount of interest income from our investment balances which increased after the completion of our initial public offering in February 2004. Our initial public offering provided us with $133.2 million in net proceeds. Additionally, interest
expense was lower in the nine months ended September 30, 2004 than the same period in 2003, since in February 2004, we used $5.8 million in proceeds from the initial public offering to repay in full balances outstanding under our loan agreement.



Provision for Income Taxes. Provision for income taxes
was $753,000 for the nine months ended September 30, 2004, and our effective tax rate was 8.0%, which reflects the utilization of net operating loss carryforwards. Provision for income taxes was $33,000 for the nine months ended September 30, 2003,
which related to taxes on foreign income.



Liquidity and Capital Resources



As of September 30, 2004, we had $150.7 million in cash,
cash equivalents and marketable securities. In February 2004, we completed an initial public offering of 10,350,000 shares of our common stock resulting in net proceeds to us of approximately $133.2 million. We used $5.8 million to pay in full
outstanding balances under our revolving credit facility and equipment loan. As of September 30, 2004, we have $10.0 million available for borrowing under the revolving credit facility and no further funds available for borrowing under the equipment
loan. The loan is collateralized by all our tangible assets. The loan agreement contains financial and nonfinancial covenants with which we must comply. As of September 30, 2004, we were in compliance with all of these covenants.



Operating Activities: Our operating activities used $5.2 million of
cash for the nine months ended September 30, 2004 and $12.9 million for the nine months ended September 30, 2003. The improvement in our cash flow resulted primarily from net income of $8.7 million for the nine months ended September 30, 2004 as
compared to a net loss of $12.9 million for the nine months ended September 30, 2003. Our accounts receivable increased $17.0 million and $5.9 million, for the nine months ended September 30, 2004 and 2003, respectively, related to increased
revenue, the timing of customer payments and the extension of credit terms to a broader base of customers. Inventories increased $8.4 million and $3.9 million for the nine months ended September 30, 2004 and 2003, respectively, as we built inventory
in order to meet the increased anticipated future demand for our products. Prepaid expenses and other current assets increased by $2.5 million for the nine months ended September 30, 2004 compared to $184,000 for the nine months ended September 30,
2003 as we licensed additional computer aided design software tools to support our incremental personnel growth and product development. Accounts payable decreased $283,000 in the nine months ended September 30, 2004, compared to an increase of $4.0
million for the nine months ended September 30, 2003, resulting primarily from the timing of payments for inventory. Our other accrued liabilities increased $9.8 million and $3.1 million during the nine months ended September 30, 2004 and 2003,
respectively, due primarily to the accrual of customer incentives.



Investing Activities. Our investing activities used $99.9 million in the nine months ended September 30, 2004, and provided cash of $13.4 million in the nine months ended September 30, 2003. Our investing activities primarily
consisted of the purchase and maturities of our marketable securities, purchases of property and equipment and the refund of a deposit from a loan agreement included in the change in other assets.



Capital expenditures were $1.9 million and $1.0 million for the nine months
ended September 30, 2004 and 2003, respectively. These expenditures primarily consisted of computer and test equipment purchases. We anticipate that further capital expenditures will be required to support future growth.



Financing Activities. Our financing activities provided cash of $127.8
million and $4.8 million in the nine months ended September 30, 2004 and 2003, respectively. The increase in cash provided in 2004 related to the net proceeds from our initial public offering of $133.2 million, partially offset by the repayment of
$5.8 million in outstanding balances on our revolving credit facilities.

Our research and development expenses were $30.6 million in the nine months ended September 30, 2004 and
$29.1 million, $23.1 million and $23.1 million for the years ended December 31, 2003, 2002 and 2001, respectively. These expenditures resulted in enhancements to our product offerings, technological know-how and inventions that have yielded numerous
issued and pending U.S. patents. We expect to continue to incur significant research and development expenses and intend to fund these expenses with operating cash flow, cash and equivalents and the revolving credit facility.



We expect to experience an increase in our operating expenses in absolute
dollars, particularly in research and development and sales and marketing expenses, for the foreseeable future in order to execute our business strategy. As a result, we anticipate that operating expenses, as well as planned capital expenditures,
will constitute a material use of our cash resources.



Some of
our major customers have converted or are expected to convert to open credit terms from letter of credit backed receivables. We expect that this change in credit terms, as well as increasing revenue, may increase our accounts receivable balances
over time and thereby consume working capital.



We believe that
our existing cash and cash equivalents and existing amounts available under our revolving credit facility will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our future capital requirements will depend on many
factors including our rate of revenue growth, the timing and extent of spending to support development efforts, the expansion of sales and marketing activities, the timing of introductions of new products and enhancements to existing products, the
costs to ensure access to adequate manufacturing capacity and the continuing market acceptance of our products. Although we are currently not a party to any agreement or letter of intent with respect to potential investments in, or acquisitions of,
complementary businesses, products or technologies, we may enter into these types of arrangements in the future, which could also require us to seek additional equity or debt financing. The sale of additional equity securities or convertible debt
securities would result in additional dilution to our stockholders. Additional debt would result in increased interest expense and could result in covenants that would restrict our operations. We have not made arrangements to obtain additional
financing and there is no assurance that such financing, if required, will be available in amounts or on terms acceptable to us, if at all.



Contractual Obligations and Off-Balance Sheet Arrangements



Information regarding our long-term debt payments, operating lease payments and capital lease payments is provided in Managements Discussion
and Analysis of Results of Operations and Financial Condition of our Form S-1 filed with the SEC on February 11, 2004. There have been no material changes in contractual obligations since December 31, 2003, except for the repayment of our $4.0
million revolving credit facility and $1.8 million equipment loan.



As of September 30, 2004, we have no off-balance sheet arrangements as defined in Item 303(a)(4) of the SECs Regulation S-K.



Recent Accounting Pronouncement



In March 2004, the Financial Accounting Standards Board (FASB) reached a consensus on EITF Issue No. 03-1, The Meaning of
Other-Than-Temporary Impairment and Its Application to Certain Investments which provides new guidance for assessing impairment losses on investments. Additionally, EITF 03-1 includes new disclosure requirements for investments that are deemed
to be temporarily impaired. In September 2004, the FASB delayed the accounting provisions of EITF 03-1; however the disclosure requirements remain effective for annual periods ending after June 15, 2004. We will evaluate the impact of EITF 03-1 once
final guidance is issued.



FACTORS THAT MAY AFFECT OUR
RESULTS



Risks Related to Our Business



Fluctuations in our operating results on a quarterly and annual basis
could cause the market price of our common stock to decline.



Our revenue and operating results have fluctuated significantly from period to period in the past and are likely to do so in the future. These fluctuations could cause the market price of our common stock to decline. As a result, you should
not rely on period to period comparisons of our operating results as an indication of our future performance. In future periods, our revenue and results of operations may be below the expectations of analysts and investors, which could cause the
market price of our common stock to decline. Factors that are likely to cause our revenue and operating results to fluctuate include those discussed in the risk factors below.

##### Table of Contents

We do not expect to sustain our recent growth rate, and we may not be able to manage our future
growth effectively.



We have experienced significant
growth in a short period of time. Our revenue has increased from $1.8 million in 2001, to $22.2 million in 2002, $87.4 million in 2003 and $128.0 million in the first nine months of 2004. We do not expect similar revenue growth rates in future
periods. Growth and expansion of our operations may place a significant strain on our resources and increased demands on our management information and reporting systems, financial and management controls and personnel. We may not be able to develop
the internal capabilities or collaborative relationships required to manage future growth and expansion or to support future operations. If we are unable to manage growth effectively, our financial results could be adversely affected.



Although we have recently achieved profitability, we may incur losses
in the future. Accordingly, we may not be able to generate sufficient revenue in the future to sustain profitability.



At September 30, 2004, we had an accumulated deficit of approximately $75.9 million. During 2003, we incurred $49.8 million in operating expenses and a
net loss of $13.2 million. In the first nine months of 2004, we incurred operating expenses of $51.6 million and generated net income of $8.7 million. To sustain profitability, we will need to maintain or increase our revenue while maintaining
reasonable cost and expense levels. We expect to increase expense levels in absolute dollars in each of the next several quarters to support increased research and development efforts related to new and existing product development and sales and
marketing efforts. These expenditures are expected to decrease as a percentage of revenue over the next several quarters if our revenue increases. Because many of our expenses are fixed in the short term, or are incurred in advance of anticipated
sales, we may not be able to decrease our expenses in a timely manner to offset any shortfall of sales. We may not be able to sustain or increase profitability on a quarterly or an annual basis.



If demand for our chipsets declines or does not grow, we will be unable
to increase or sustain our revenue and our business will be severely harmed.



We derive substantially all of our revenue from the sale of chipsets for wireless local area networking applications. We currently expect our chipsets for wireless applications to account for substantially all of our
revenue for the foreseeable future. If we are unable to develop new products in a timely manner or demand for our chipsets declines as a result of competition or technological changes, it would have a material negative impact on our business,
operating results and financial position and our competitive position. The markets for our products are characterized by frequent introduction of next generation and new products, short product life cycles and significant price competition. If we or
our customers are unable to manage product transitions in a timely and cost-effective manner, our business and results of operations will suffer. In addition, frequent technology changes and introduction of next generation products may result in
inventory obsolescence, which could reduce our gross margins and adversely affect our operating performance.



Since we have limited visibility as to the volume of sales of our products by our customers and inventory levels of our products held by our
customers, our ability to forecast accurately future demand for and sales of our products is limited.



We sell our chipsets to OEMs who integrate our chipsets into their products or to ODMs who include our chipsets in the products they supply to OEMs. We
have limited visibility as to the volume of our products that our OEM and ODM customers are selling to their customers or carrying in their inventory. If our customers have excess inventory or experience a slowing of products sold through to their
end customers, it may adversely impact our future sales.



The average selling prices of products in our markets have historically decreased rapidly and will likely do so in the future, which could harm our revenue and gross profits.



The products we develop and sell are used for high volume applications and
are subject to rapid declines in average selling prices. Our average selling prices have decreased significantly in order to meet market demand, and we expect that we will continue to reduce prices in the future. Reductions in our average selling
prices to one customer could impact our average selling prices to all customers. Historically, we have been able to substantially offset reductions in our average selling prices with decreases in our product and operating costs and increases in our
unit volumes. Our financial results will suffer if we are unable to offset any future reductions in our average selling prices by increasing our unit volumes, reducing our costs or developing new or enhanced products on a timely basis with higher
selling prices or gross margins. While gross margins may decline as a result of reductions in average selling prices, we may continue to incur research and development costs at higher or existing levels to develop future products. This continued
spending would have an adverse impact on our immediate operating results if our revenue does not continue to grow or our gross margins decline.



We may not be able to compete effectively and increase or maintain revenue and market share.



We may not be able to compete successfully against current or potential
competitors. If we do not compete successfully, our market share and revenue may decline. We compete with large semiconductor manufacturers and designers and start-up integrated

circuit companies. Most of our current and potential competitors have longer operating histories, significantly greater
resources and name recognition and a larger base of customers than we do. This may allow them to respond more quickly than us to new or emerging technologies or changes in customer requirements. In addition, these competitors may have greater
credibility with our existing and potential customers. Moreover, our competitors have been doing business with customers for a longer period of time and have established relationships, which may provide them with information regarding future trends
and requirements that may not be available to us. In addition, some of our larger competitors may be able to provide greater incentives to customers through rebates and marketing development funds and similar programs. Some of our competitors with
multiple product lines may bundle their products to offer a broader product portfolio or integrate wireless functionality into other products that we do not sell, which may make it difficult for us to gain or maintain market share. For example,
Intel markets its Centrino mobile technology brand and we believe they provide a substantial marketing development fund incentive for buyers of a combination of its microprocessor, related chipsets and wireless networking module that use the brand.



We depend on key personnel and consultants to operate
our business, and if we are unable to retain our current personnel and hire additional personnel, our ability to develop and successfully market our products could be harmed.



We believe our future success will depend in large part upon our ability to attract and retain highly skilled managerial,
engineering and sales and marketing personnel. The loss of any key employees or the inability to attract or retain qualified personnel, including engineers and sales and marketing personnel, could delay the development and introduction of, and harm
our ability to sell, our products and harm the markets perception of us. We believe that our future success is highly dependent on the contributions of Dr. Craig H. Barratt, our President and Chief Executive Officer and Richard G. Bahr, our
Vice President of Engineering. We do not have long-term employment contracts with these or any other key personnel, and their knowledge of our business and industry would be extremely difficult to replace.



There is currently a shortage of qualified technical personnel with
significant experience in the design, development, manufacture, marketing and sales of integrated circuits for use in wireless networking products. Our key technical personnel and consultants represent a significant asset and serve as the source of
our technological and product innovations. We may not be successful in attracting and retaining sufficient numbers of technical personnel to support our business plan.



If we fail to develop and introduce new products and enhancements for wireless networking and other wireless
applications or if our proprietary features do not achieve market acceptance on a timely basis, our ability to attract and retain customers could be impaired, and our competitive position may be harmed.



The wireless market is characterized by rapidly changing technology,
evolving industry standards, rapid changes in customer requirements and frequent product introductions. We must continually design, develop and introduce new products with improved features to be competitive. All of our products introduced to date
have been for use in the wireless networking market. We may also need to develop and introduce new products for use in applications other than wireless networking to be successful. Our products may not achieve market acceptance or adequately address
the changing needs of the wireless networking market, and we may not be successful in developing and marketing new products or enhancements to our existing products on a timely basis. The introduction of products embodying new technologies, the
emergence of new industry standards or changes in customer requirements could render our existing products obsolete and unmarketable. In addition, we introduce from time to time products with proprietary enhancements. Although we believe our
products are fully compliant with applicable industry standards, proprietary enhancements may not in the future result in full conformance with existing industry standards under all circumstances. Our introduction of proprietary features involves
risks associated with market acceptance of these new products and certification by industry standards groups. We have reviewed the rules and regulations of the various standards bodies and related industry organizations to which we belong or with
which we are affiliated, and we believe there is not a significant risk that action would be taken that would undermine our ability to continue to exploit our affiliation with these organizations.



The development of our products is highly complex. We occasionally have
experienced delays in completing the development and introduction of new products and product enhancements, and we could experience delays in the future. Unanticipated problems in developing wireless products could also divert substantial
engineering resources, which may impair our ability to develop new products and enhancements and could substantially increase our costs. Even if the new and enhanced products are introduced to the market, we may not be able to achieve market
acceptance of these products and our proprietary features in a timely manner.



We depend on a small number of customers for a significant portion of our revenue. If we fail to retain or expand customer relationships, our revenue could decline.



We derive a significant portion of our revenue from a small number of
customers, and we anticipate that we will continue to do so in the foreseeable future. These customers may decide not to purchase our products at all, to purchase fewer products than they did in the past, for example due to an increase in inventory,
or to alter their purchasing patterns in some other way, particularly because substantially all of our sales are made on a purchase order basis, which permits our customers to cancel, change or delay product purchase commitments with little or no
notice to us and without penalty.

In the first nine months of 2004, Hon-Hai Precision Industry (formerly Ambit Microsystems), Askey
Computer Corporation and Global Sun Technology, Inc. accounted for 26%, 16% and 12% of our net revenue, respectively. In the year ended December 31, 2003, Global Sun Technology, Inc. and Ambit Microsystems accounted for 28% and 20% of our net
revenue, respectively. Some of our original equipment manufacturer customers are also original design manufacturer customers, which may increase the impact of the loss of any customer. We must obtain orders from new customers on an ongoing basis to
increase our revenue and grow our business. Sales to our largest customers have fluctuated significantly from period to period primarily due to a change in our distribution model from direct sales to an increasing number of sales to original design
manufacturers and the continued diversification of our customer base in our current markets. We believe that sales will likely continue to fluctuate significantly in the future as we enter into new markets. The loss of any significant customer, a
significant reduction in sales we make to them, or any problems collecting receivables from them would likely harm our financial condition and results of operations.



We will have difficulty selling our products if customers do not design our products into their product offerings or
if our customers product offerings are not commercially successful.



We sell our products directly to original equipment manufacturers, who include our chipsets in their products, and to original design manufacturers, who include our chipsets in the products they supply to original
equipment manufacturers. Our products are generally incorporated into our customers products at the design stage. As a result, we rely on original equipment manufacturers to design our products into the products they sell. Without these design
wins, our business would be materially and adversely affected. We often incur significant expenditures on the development of a new product without any assurance that an original equipment manufacturer will select our product for design into its own
product. Once an original equipment manufacturer designs a competitors product into its product offering, it becomes significantly more difficult for us to sell our products to that customer because changing suppliers involves significant
cost, time, effort and risk for the customer. Furthermore, even if an original equipment manufacturer designs one of our products into its product offering, we cannot be assured that its product will be commercially successful, that we will receive
any revenue from that manufacturer or that a successor design will include one of our products.



The complexity of our products could result in unforeseen delays or expenses from undetected defects, errors or bugs in hardware or software, which
could reduce the market acceptance for our new products, damage our reputation with current or prospective customers and adversely affect our operating costs.



Highly complex products such as our chipsets and the related reference designs we provide to our customers frequently
contain defects, errors and bugs when they are first introduced or as new versions are released. We may in the future experience these defects, errors and bugs. If any of our products have reliability, quality, or compatibility problems, we may not
be able to successfully correct these problems. In addition, if any of our proprietary features contain defects, errors or bugs when first introduced or as new versions are released, we may be unable to correct these problems. Consequently, our
reputation may be damaged and customers may be reluctant to buy our products, which could harm our ability to retain existing customers and attract new customers and our financial results. In addition, these defects, errors or bugs could interrupt
or delay sales to our customers. If any of these problems are not found until after we have commenced commercial production of a new product, we may be required to incur additional development costs and product recalls, repairs or replacement costs.
These problems may also result in claims against us by our customers or others.



Because we do not have long-term commitments from our customers, we must estimate customer demand, and errors in our estimates can have negative effects on our inventory levels, sales and operating
results.



Our sales are largely made on the basis of
individual purchase orders rather than long-term purchase commitments. Our customers have the right to cancel or defer some purchase orders. We have experienced in the past cancellations or deferrals of purchase orders, and additional cancellations
and deferrals may occur from time to time. We have historically placed firm orders for products with our foundries up to approximately 16 weeks prior to the anticipated delivery date and typically prior to receiving an order for the product.
Therefore, our order volumes are based on our forecasts of demand from our customers. This process requires us to make multiple demand forecast assumptions, each of which may introduce error into our estimates. If we overestimate customer demand or
incorrectly estimate product mix, we may allocate resources to manufacturing products that we may not be able to sell when we expect or at all. As a result, we would have excess inventory, which would harm our financial results. Conversely, if we
underestimate customer demand or if insufficient manufacturing capacity is available, we would forego revenue opportunities, lose market share and damage our customer relationships. On occasion, we have been unable to adequately respond to increases
in customer purchase orders, and therefore, were unable to complete, or needed to delay, sales. We have in the past, and may in the future, allocate our supply among our customers. Product allocation may result in the loss of current customers, and
if we are unable to commit to provide specified quantities of products over a given period of time, we will not attract new customers. The failure to maintain customer relationships would decrease our revenue and harm our business.

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



To remain competitive, we continually work to improve our chipsets and, in particular, our high-performance radio frequency products, to be
manufactured using increasingly smaller geometries and to achieve higher levels of design integration. These ongoing efforts require us from time to time to modify the manufacturing processes for our products and to redesign some products. To remain
competitive, our chipset must be redesigned from time to time, which may result in delays in product deliveries. We periodically evaluate the benefits, on a product-by-product basis, of migrating to smaller geometry process technologies to reduce
our costs. In the past, we have experienced some difficulties in shifting to smaller geometry process technologies or new manufacturing processes, which resulted in reduced manufacturing yields, delays in product deliveries and increased expenses.
In addition, while we purchase wafers from foundries, we also assume the yield risk related to manufacturing these wafers into die. We may face similar difficulties, delays and expenses in the future. We depend on our relationships with our
foundries to transition to smaller geometry processes successfully and cannot assure that our foundries will be able to effectively manage the transition. If our foundries, or we, experience significant delays in this transition or fail to
efficiently implement these transitions, our business, financial condition and results of operations could be adversely affected.



We rely on a limited number of independent foundries and subcontractors for the manufacture, assembly and testing of our chipsets, and the failure
of any of these third-party vendors to deliver products or otherwise perform as requested could damage our relationships with our customers, decrease our sales and limit our growth.



We do not have our own manufacturing or assembly facilities and have very
limited in-house testing facilities. Therefore, we must rely on third-party vendors to manufacture, assemble and test the products we design. We rely on Taiwan Semiconductor Manufacturing Corporation in Taiwan and Semiconductor Manufacturing
International Corporation in Shanghai, China to produce all of our chips. We also rely on Amkor Technology, Inc. in China and Korea and ASAT Holdings Limited in Hong Kong, Advanced Semiconductor Engineering, Inc. and Siliconware Precision Industries
Co., Ltd., both of which are in Taiwan, ST Assembly Test Services Ltd. in Singapore and other third-party assembly and test subcontractors to assemble, package and test our products. If these vendors do not provide us with high-quality products,
services and production and test capacity in a timely manner, or if one or more of these vendors terminates its relationship with us, we may be unable to obtain satisfactory replacements to fulfill customer orders on a timely basis, our
relationships with our customers could suffer, our sales could decrease and our growth could be limited.



We face risks associated with relying on third-party vendors for the manufacture, assembly and testing of our chipsets.



We face significant risks associated with relying on third-party vendors,
including:



| |  | reduced control over product cost, delivery schedules and product quality;
| | - | --------------------------------------------------------------------------



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



| |  | inability to achieve sufficient production, increase production or test capacity and achieve acceptable yields on a timely basis;
| | - | ---------------------------------------------------------------------------------------------------------------------------------



| |  | increased exposure to potential misappropriation of our intellectual property;
| | - | ------------------------------------------------------------------------------



| |  | shortages of materials that foundries use to manufacture products;
| | - | ------------------------------------------------------------------



| |  | capacity shortages; and
| | - | -----------------------



| |  | labor shortages or labor strikes.
| | - | ---------------------------------



We do not have long-term supply contracts with our third-party manufacturing vendors and they may allocate capacity to other customers and may not
allocate sufficient capacity to us to meet future demands for our products.



We currently do not have long-term supply contracts with any of our third-party vendors. Therefore, they are not obligated to perform services or supply products to us for any specific period, in any specific
quantities, or at any specific price, except as may be provided in a particular accepted purchase order. None of our third-party foundry or assembly and test vendors has provided contractual assurances to us that adequate capacity will be available
to us to meet future demand for our products. These foundries and assembly and test vendors may allocate capacity to the production of other companies products while reducing deliveries to us on short notice. In particular, other customers
that are larger and better financed than us or that have long-term agreements with these foundries or assembly and test vendors may cause these foundries or assembly and test vendors to reallocate capacity to those

customers, decreasing the capacity available to us. If we enter into costly arrangements with suppliers that include
nonrefundable deposits or loans in exchange for capacity commitments, commitments to purchase specified quantities over extended periods or investment in a foundry, our operating results could be harmed. To date, we have not entered into such
arrangements with our suppliers. If we need another integrated circuit foundry or assembly and test subcontractor because of increased demand, or the inability to obtain timely and adequate deliveries from our providers, we might not be able to
cost-effectively and quickly retain other vendors to satisfy our requirements.



If our third-party foundries or suppliers do not achieve satisfactory yields or quality, our relationships with our customers and our reputation will be harmed.



The fabrication of chipsets is a complex and technically demanding process.
Minor deviations in the manufacturing process can cause substantial decreases in yields, and in some cases, cause production to be suspended. Our third-party foundries and suppliers have from time to time experienced manufacturing defects and
reduced manufacturing yields. Changes in manufacturing processes or the inadvertent use of defective or contaminated materials by our foundries could result in lower than anticipated manufacturing yields or unacceptable performance. Many of these
problems are difficult to detect at an early stage of the manufacturing process and may be time consuming and expensive to correct. In addition, designing radio frequency circuits using standard, complementary metal-oxide semiconductor processes is
difficult and can result in unsatisfactory yields. Because we purchase wafers, our exposure to low wafer yields from our foundries is increased. Poor yields from our foundries or defects, integration issues or other performance problems in our
products could cause us significant customer relations and business reputation problems, or force us to sell our products at lower gross margins and therefore harm our financial results. In addition, manufacturing defects may not be detected by our
testing, or may be caused by defective packaging of our products by our third-party suppliers. If these defects arise or are discovered after we have shipped our products, our reputation and business would suffer.



If we fail to secure or protect our intellectual property rights,
competitors may be able to use our technologies, which could weaken our competitive position, reduce our revenue or increase our costs.



We rely on a combination of patent, copyright, trademark and trade secret laws, confidentiality procedures and licensing arrangements to establish and
protect our proprietary rights. Our pending patent applications may not result in issued patents, and our existing and future patents may not be sufficiently broad to protect our proprietary technologies or may be held invalid or unenforceable in
court. Policing unauthorized use of our products is difficult and we cannot be certain that the steps we have taken will prevent the misappropriation or unauthorized use of our technologies, particularly in foreign countries where the laws may not
protect our proprietary rights as fully as United States law. Any patents we have obtained, or may obtain in the future, may not be adequate to protect our proprietary rights. Our competitors may independently develop or may have already developed
similar technology, duplicate our products or design around any patents issued to us or other intellectual property rights. In addition, we may be required to license our patents as a result of our participation in various standards organizations.



Because we license some of our software source code
directly to customers, we face increased risks that our trade secrets will be exposed through inadvertent or intentional disclosure, which could harm our competitive position or increase our costs.



We license some of our software source code to our customers, which
increases the number of people who have access to some of our trade secrets and other proprietary rights. Contractual obligations of our licensees not to disclose or misuse our source code may not be sufficient to protect us from disclosure or
misuse. The costs of enforcing contractual rights could substantially increase our operating costs and may not ultimately succeed in protecting our proprietary rights. If our competitors access our source code, they may gain further insight into the
technology and design of our products, which would harm our competitive position.



Intellectual property litigation, which is common in our industry, could be costly, harm our reputation, limit our ability to license or sell our proprietary technologies or products and divert the attention of
management and technical personnel.



The wireless
networking market is characterized by frequent litigation regarding patent and other intellectual property rights. In the last few years, we received several written notices or offers from our competitors and others claiming to have patent rights in
certain technology and inviting us to license this technology and related patents that apply to the Institute of Electrical and Electronics Engineers(IEEE) family of wireless local area networking standards, including the 802.11b,
802.11g and 802.11a wireless standards as well as other technology and patents relevant to other standards related to our chips, software and system solutions. These notices or offers have been made directly to us and through our U.S. and foreign
customers. We have certain indemnification obligations to customers with respect to any infringement of third-party patents and intellectual property rights by our products. We have responded directly, or indirectly through our customers, to all of
these notices, and continue to correspond regarding the offers with some of the parties that have sent the notices. None of these notices or offers to license has included an explicit threat of, or resulted in, litigation against us. While at least
one of our customers has been sued by the holder of a patent related to 802.11b, 802.11g and 802.11a technology, none of these notices or offers to license has included an explicit threat of, or resulted in, litigation against us.

##### Table of Contents

Questions of infringement in the wireless networking market involve highly technical and subjective
analyses. Litigation may be necessary in the future to enforce any patents we may receive and other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend
against claims of infringement or invalidity, and we may not prevail in any future litigation. If litigation were to be filed against us in connection with an offer to license technology or claims of infringement, our business could be harmed.
Litigation, whether or not determined in our favor or settled, could be costly, could harm our reputation and could divert the efforts and attention of our management and technical personnel from normal business operations. In addition, adverse
determinations in litigation could result in the loss of our proprietary rights, subject us to significant liabilities, require us to seek licenses from third parties or prevent us from licensing our technology or selling our products, any of which
could seriously harm our business. Any of these consequences could result from litigation whether initiated by our competitors or others, including those that have already sent notices or offers to us and our customers claiming patent rights and
offering licenses.



Any potential dispute involving our
patents or other intellectual property could also include our industry partners and customers, which could trigger our indemnification obligations to them and result in substantial expense to us.



In any potential dispute involving our patents or other intellectual
property, our customers or licensees could also become the target of litigation, and certain customers have received notices of written offers from our competitors and others claiming to have patent rights in certain technology and inviting our
customers to license this technology. At least one customer has been sued outside the U.S. for allegedly infringing a patent related to 802.11b, 802.11g and 802.11a technology. Because we indemnify our customers for intellectual property claims made
against them for products incorporating our technology, any litigation could trigger technical support and indemnification obligations in some of our license or sales agreements, which could result in substantial expenses. In addition to the time
and expense required for us to supply support or indemnification to our customers, any such litigation could severely disrupt or shut down the business of our customers, which in turn could hurt our relations with our customers and cause the sale of
our proprietary technologies and products to decrease.



We face business, political, regulatory, operational, financial and economic risks because most of our operations and sales activities take place outside of the United States.



A significant portion of our products is sold to customers outside the
United States and Canada. Sales to customers in Asia accounted for substantially all of our net revenue in the first nine months of 2004 and for the year 2003. Because many of our original design manufacturer customers are located in Asia, we
anticipate that substantially all of our revenue will continue to be represented by sales to customers in that region. In addition, we conduct research and development activities in India and have sales, marketing and support personnel in Japan,
Taiwan and China. Our success depends upon continued expansion of our international operations. Our international business involves a number of risks, including:



| |  | multiple, conflicting and changing laws and regulations, export and import restrictions, employment laws, regulatory requirements and other governmental approvals, permits and
licenses;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | difficulties in staffing and managing foreign operations as well as cultural differences;
| | - | -----------------------------------------------------------------------------------------



| |  | trade restrictions or higher tariffs that favor local competition in some countries;
| | - | ------------------------------------------------------------------------------------



| |  | difficulties of managing sales representatives, especially because we expect to increase our sales through our sales representatives;
| | - | -------------------------------------------------------------------------------------------------------------------------------------



| |  | inadequate local infrastructure and transportation delays;
| | - | ----------------------------------------------------------



| |  | financial risks, such as longer payment cycles, greater difficulty collecting accounts receivable and exposure to foreign currency exchange rate fluctuations;
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | failure by us or our customers to gain regulatory approval for use of our products; and
| | - | ---------------------------------------------------------------------------------------



| |  | political and economic instability, including wars, terrorism, and political unrest, recurrence of the SARS outbreak, boycotts, curtailment of trade and other business restrictions.
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Any of these factors could significantly harm
our future international sales and operations, consequently, our revenue and results of operations and business and financial condition.

##### Table of Contents

Our headquarters are located in California and our third-party foundries and subcontractors are
concentrated in Asia and elsewhere in the Pacific Rim, areas subject to significant earthquake risks. Any disruption to the operations of these foundries and subcontractors resulting from earthquakes or other natural disasters could cause
significant delays in the production or shipment of our products.



Taiwan Semiconductor Manufacturing Corporation and Semiconductor Manufacturing International Corporation, which manufacture our chipsets and perform substantially all of our assembly and testing facilities, are
located in Asia. In addition, our headquarters are located in Northern California. The risk of an earthquake in the Pacific Rim region, including Asia and Northern California, is significant due to the proximity of major earthquake fault lines. In
September 1999, a major earthquake in Taiwan affected the facilities of several of these third-party contractors, as well as other providers of these services. As a result of this earthquake, these contractors suffered power outages and disruptions
that impaired their production capacity. The occurrence of additional earthquakes or other natural disasters could result in the disruption of our foundry or assembly and test capacity. We may not be able to obtain alternate capacity on favorable
terms, if at all.



We rely upon third parties for
technology that is integrated into some of our products, and if we are unable to continue to use this technology and future technology or the technology fails to operate, our ability to sell technologically advanced products would be
limited.



We rely on third parties for technology that
is integrated into some of our products. If we are unable to continue to use or license on reasonable terms third-party technologies used in some of our products or the technology fails to operate, we may not be able to secure alternatives in a
timely manner and our business would be harmed.



Risks Related to Our
Industry



Any future downturns in the semiconductor
industry may reduce our revenue and result in excess inventory.



The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence and price erosion, evolving standards, short product life cycles and wide
fluctuations in product supply and demand. The industry has, from time to time, experienced significant downturns, often connected with, or in anticipation of, maturing product cycles of both semiconductor companies and their customers
products and declines in general economic conditions. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. Any future downturns may
reduce our revenue or our percentage of revenue growth on a quarter-to-quarter basis and result in us having excess inventory. Furthermore, any upturn in the wireless networking market in which we sell our chipsets could result in increased
competition for access to limited third-party foundry, assembly and test capacity.



Changes in current laws or regulations or the imposition of new laws or regulations could impede the sale of our products or otherwise harm our business.



Wireless networks can only operate in the frequency bands, or spectrum,
allowed by regulators and in accordance with rules governing how the spectrum can be used. The Federal Communications Commission, or the FCC, in the United States, as well as regulators in foreign countries, have broad jurisdiction over the
allocation of frequency bands for wireless networks. We therefore rely on the FCC and international regulators to provide sufficient spectrum and usage rules. For example, countries such as China, Japan or Korea heavily regulate all aspects of their
wireless communication industries, and may restrict spectrum allocation or usage, or may impose requirements that render our products or our customers products unmarketable in these jurisdictions. If this were to occur, it would make it
difficult for us to sell our products in that region. In addition, some of our chipsets operate in the 5 gigahertz, or GHz, band, which is also used by government and commercial services such as military and commercial aviation. The FCC and European
regulators have traditionally protected government uses of the 5GHz, bands by setting power limits and indoor and outdoor designation and requiring that wireless local area networking devices not interfere with other users of the band such as
government and civilian satellite services. Changes in current laws or regulations, reversal of usage rights, or the imposition of new laws and regulations in the United States or elsewhere regarding the allocation and usage of the 5 GHz band on us,
our customers or the industries in which we operate may materially and adversely impact the sale of our products and our business, financial condition and results of operations.



Rapidly changing standards could make our products obsolete, which would cause our operating results to
suffer.



We design our products to conform to standards set by
industry standards bodies such as the Institute of Electrical and Electronics Engineers, Inc. We also depend on industry groups such as the WiFi Alliance to certify and maintain certification of our products. If our customers adopt new or competing
industry standards with which our products are not compatible, or such industry groups fail to adopt standards with which our products are compatible, our existing products would become less desirable to our customers and our sales would suffer. The
emergence of markets for our chipsets is affected by a variety of factors beyond our control. In particular, our products are designed to conform to current specific industry standards. Competing standards may emerge that are preferred by our
customers, which could also reduce our sales and require us to make significant expenditures to develop new products. For example,

##### Table of Contents

the IEEE has initiated working group proceedings directed at promulgating a new wireless local area networking standard,
called 802.11n, that may be, or may be perceived by customers as being, superior to the standards with which our current products comply. If adoption of 802.11n and pre-802.11n products becomes widespread before we offer such products, we will lose
customers and revenue and our business will be harmed.



If our customers or the industries using wireless technology prefer to integrate wireless capability into other products, we may not be able to compete effectively, we will lose customers, our revenue will decline and our business
will be harmed.



We have adopted the strategy of
maintaining wireless technology on a chipset that is separate from functionality contained on other chips within a product. Our customers or the industries using wireless technology may prefer to integrate wireless capability into other products
such as DSL modems, or determine that an integrated chip with multiple functionality results in products that perform better or are less expensive or more efficient to manufacture. If wireless functionality becomes commonly integrated with other
functionality, the market for our products may decline. Consequently, we may miss product cycles in order to redesign our products, and we may not be able to forge strategic relationships necessary in order to design and arrange for the production
of chips that include multiple functionality. If we miss product cycles, we will lose customers, our revenue will decline and our business will be harmed.



The proliferation of wireless devices may expand beyond the capacity of the channels available in the 2.4GHz or 5 GHz bands, which may overload the
networks and result in decreased market demand for our products.



Wireless networks currently operate in the 2.4 GHz or 5 GHz bands, within which there are a limited number of channels available for use. The increasing number of wireless devices and networks may overburden the
frequency bands and overload the networks. Recent studies have predicted that congestion in the 2.4 GHz band could result from the increasing number of wireless devices using that band. If this occurs, our customers or the industries in which we
operate may be adversely affected because the networks become inoperable or because only a limited number of devices will be able to access the networks. In turn, we may experience a decrease in market demand for our products that would adversely
impact our business and results of operations.



We may
experience a decrease in market demand due to uncertain economic conditions in the United States and in international markets, which has been further exacerbated by the concerns of terrorism, war and social and political instability.



Economic growth in the United States and international
markets has slowed significantly and the United States economy has recently been in a recession. The timing of a full economic recovery is uncertain. In addition, the terrorist attacks in the United States, the continued presence of United States
military forces in Iraq, and turmoil in the Middle East have contributed to the uncertainty in the United States economy and may lead to a decline in economic conditions, both domestically and internationally. Further terrorist acts and similar
events, or additional wars in general, could contribute further to a slowdown of the market demand for goods and services, including demand for our products. If the economy declines as a result of the recent economic, political and social turmoil,
or if there are further terrorist attacks in the United States or elsewhere, we may experience decreases in the demand for our products and services, which may harm our operating results.



Risks related to the market for our common stock



Because the Nasdaq National Market is likely to continue to experience extreme price and volume fluctuations, the
price of our stock may decline.



Since we completed
our initial public offering in February 2004, the market price of our shares has been and likely will continue to be highly volatile and could be subject to wide fluctuations in response to numerous factors, including the following:



| |  | actual or anticipated variations in our quarterly operating results or those of our competitors;
| | - | ------------------------------------------------------------------------------------------------



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



| |  | introduction and adoption of new industry standards;
| | - | ----------------------------------------------------



| |  | changes in financial estimates or recommendations by securities analysts;
| | - | -------------------------------------------------------------------------



| |  | changes in the market valuations of our competitors;
| | - | ----------------------------------------------------



| |  | announcements by us or our competitors of significant acquisitions or partnerships; and
| | - | ---------------------------------------------------------------------------------------



| |  | sales of our common stock.
| | - | --------------------------

##### Table of Contents

Many of these factors are beyond our control and may negatively impact the market price of our common
stock, regardless of our performance. In addition, the stock market in general, and the market for technology and semiconductor companies in particular, have been highly volatile. Our common stock may not trade at the same levels of shares as that
of other semiconductor and technology companies, and shares of semiconductor and technology companies, in general, may not sustain their current market prices. In the past, securities class action litigation has often been brought against a company
following periods of volatility in the market price of its securities. We may be the target of similar litigation in the future. Securities litigation could result in substantial costs and divert managements attention and resources, which
could seriously harm our business and operating results.



Our corporate actions are substantially controlled by officers, directors, principal stockholders and affiliated entities.



Our directors, executive officers and their affiliated entities beneficially own approximately 42% of our outstanding common stock. One of our directors,
Teresa H. Meng, owns approximately 6% of our common stock, including shares subject to options that are immediately exercisable as of September 30, 2004. Including shares deemed beneficially owned in accordance with the rules of the SEC, but with
respect to which they disclaim beneficial ownership except to the extent of their pecuniary interests therein, Forest Baskett, William B. Elmore and Andrew S. Rappaport beneficially own approximately 8%, 10% and 8%, respectively. These stockholders,
if they acted together, could exert substantial control over matters requiring approval by our stockholders, including electing directors and approving mergers or other business combination transactions. This concentration of ownership may also
discourage, delay or prevent a change in control of our company, which could deprive our stockholders of an opportunity to receive a premium for their stock as part of a sale of our company and might reduce our stock price. These actions may be
taken even if they are opposed by our other stockholders.



Our ability to raise capital in the future may be limited and our failure to raise capital when needed could prevent us from executing our growth strategy.



We believe that our existing cash and cash equivalents and existing amounts available under our revolving credit facility,
together with the net proceeds from the initial public offering of our common stock completed in February 2004, will be sufficient to meet our anticipated cash needs for at least the next 12 months. The timing and amount of our working capital and
capital expenditure requirements may vary significantly depending on numerous factors, including:



| |  | market acceptance of our products;
| | - | ----------------------------------



| |  | the need to adapt to changing technologies and technical requirements;
| | - | ----------------------------------------------------------------------



| |  | the existence of opportunities for expansion; and
| | - | -------------------------------------------------



| |  | access to and availability of sufficient management, technical, marketing and financial personnel.
| | - | --------------------------------------------------------------------------------------------------



If our capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity
securities or debt securities or obtain debt financing. The sale of additional equity securities or convertible debt securities would result in additional dilution to our stockholders. Additional debt would result in increased expenses and could
result in covenants that would restrict our operations. We have not made arrangements to obtain additional financing and there is no assurance that financing, if required, will be available in amounts or on terms acceptable to us, if at all.



Delaware law and our corporate charter and bylaws
contain anti-takeover provisions that could delay or discourage takeover attempts that stockholders may consider favorable.



Provisions in our certificate of incorporation may have the effect of delaying or preventing a change of control or changes in our management. These
provisions include the following:



| |  | the right of the board of directors to elect a director to fill a vacancy created by the expansion of the board of directors;
| | - | -----------------------------------------------------------------------------------------------------------------------------



| |  | the establishment of a classified board of directors requiring that not all members of the board be elected at one time;
| | - | ------------------------------------------------------------------------------------------------------------------------



| |  | the prohibition of cumulative voting in the election of directors which would otherwise allow less than a majority of stockholders to elect director candidates;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the requirement for advance notice for nominations for election to the board of directors or for proposing matters that can be acted upon at a stockholders meeting;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



26

##### Table of Contents

| |  | the ability of the board of directors to alter our bylaws without obtaining stockholder approval;
| | - | -------------------------------------------------------------------------------------------------



| |  | the ability of the board of directors to issue, without stockholder approval, up to 10,000,000 shares of preferred stock with terms set by the board of directors, which rights could
be senior to those of common stock;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the required approval of holders of at least two-thirds of the shares entitled to vote at an election of directors to adopt, amend or repeal our bylaws or amend or repeal the
provisions of our certificate of incorporation regarding the election and removal of directors and the ability of stockholders to take action;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the required approval of holders of at least two-thirds of the shares entitled to vote at an election of directors to remove directors for cause; and
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the elimination of the right of stockholders to call a special meeting of stockholders and to take action by written consent.
| | - | -----------------------------------------------------------------------------------------------------------------------------



In addition, because we are incorporated in Delaware, we are governed by the
provisions of Section 203 of the Delaware General Corporation Law. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us. These provisions in our
certificate of incorporation, bylaws and under Delaware law could discourage potential takeover attempts and could reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price
being lower than they would without these provisions.



Item 3.Quantitative and Qualitative Disclosures About Market Risk



The primary objectives of our investment activity are, in order of importance, to preserve principal, provide liquidity and maximize the income without
significantly increasing the risk. Some of the securities we invest in are subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we
maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, money market funds, government and non-government debt securities and certificates of deposit. The risk associated with
fluctuating interest rates is limited to our investment portfolio and we do not believe that a 10% change in interest rates will have a significant impact on our interest income. As of September 30, 2004, our investments were in money market funds,
commercial paper, corporate notes, foreign debt securities, market auction preferred stock and U.S. government securities.



Our exposure to market risk also relates to the increase or decrease in the amount of interest we must pay on our outstanding debt instruments, primarily
certain borrowings under the revolving credit facility. Our revolving credit facility provides financing up to $10.0 million for working capital requirements. As of September 30, 2004, no balances were outstanding under the revolving credit
facility. The loan bears interest at the banks prime rate plus 1.0%. We do not believe that a 10% change in the prime rate would have a significant impact on our interest expense.



To date, our international customer agreements have been denominated solely in U.S. dollars, and accordingly, we have not
been exposed to foreign currency exchange rate fluctuations related to customer agreements, and do not currently engage in foreign currency hedging transactions. However, the functional currency of our operations in Japan, Taiwan and India is the
U.S. dollar and as the local expenditures are denominated in the local currencies of Japan, Taiwan and India, respectively, we are subject to foreign currency exchange rate fluctuations associated with remeasurement to U.S dollars. A hypothetical
change of 10% in the foreign currency exchange rates would not have a material impact on our consolidated financial position or results of operations.



Item 4.Controls and Procedures



(a) Evaluation of disclosure controls and procedures. We maintain disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the
Exchange Act), that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in
Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding
required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance
that the objectives of the disclosure controls and procedures are met. Our disclosure controls and procedures have been designed to meet, and management believes that they meet, reasonable assurance standards. Additionally, in designing disclosure
controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures 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.

##### Table of Contents

Based on their evaluation as of the end of the period covered by this quarterly report on Form 10-Q, our
Chief Executive Officer and Chief Financial Officer have concluded that, subject to the limitations noted above, our disclosure controls and procedures were effective to ensure that material information relating to us, including our consolidated
subsidiaries, is made known to them by others within those entities, particularly during the period in which this quarterly report on Form 10-Q was being prepared.



(b) Changes in internal control over financial reporting. There was no change in our internal control over
financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified in connection with the evaluation described in Item 4 above that occurred during the period covered by this quarterly report that has materially affected, or is
reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION



Item 1.Legal Proceedings.



We are not involved in any legal matters that management believes will have a material adverse effect on our business. Many companies in the semiconductor, networking, software and related industries have a
significant number of patents and have demonstrated a willingness to instigate litigation based on allegations of patent, trademark and other claims of infringement. From time to time, we have received, and expect to continue to receive, notices of
claims of infringement, misappropriation or misuse of other parties proprietary rights. Some of these claims may lead to litigation.



Item 2.Unregistered Sales of Equity Securities and Use of Proceeds.



(a) Not applicable



(b) On February 18, 2004, we completed an initial public offering of 10,350,000 shares of our common stock. The shares of common stock sold in the
offering were registered under the Securities Act of 1933 on a Registration Statement on Form S-1 (No. 333-110807). The Registration Statement was declared effective by the Securities and Exchange Commission on February 11, 2004. The initial public
offering price was $14.00 per share, and the aggregate gross proceeds to us were $144.9 million. After deducting the underwriting discounts and commissions of $10.1 million and the offering expenses of approximately $1.6 million, the net proceeds to
us from the offering were approximately $133.2 million.



From
February 11, 2004, until September 30, 2004, we used the following net proceeds from the offering: In February 2004, we used $5.8 million of the net offering proceeds to repay debt owed to Silicon Valley Bank, and in the second and third quarters of
2004, we used a total of $7.4 million to fund working capital requirements. We continue to invest the remaining proceeds in short-term, investment grade, interest-bearing instruments.



(c) The following table provides information with respect to purchases made by us or on our behalf or on behalf of any
affiliated purchaser, as defined in Rule 10b-18(a)(3) under the Securities Exchange Act of 1934, of shares of our common stock during each of the three months ended September 30, 2004 (in thousands, except per share data):
