Net income for the three and six months ended June 30, 2006 included stock-based compensation
expense totaling $3,257 and $6,230 before tax for stock options and purchases under the Companys Employee Stock Purchase Plan recorded by the Company as a result of its adoption of SFAS123R on January 1, 2006. There was no stock-based
compensation expense related to employee stock purchases under SFAS 123 for the three and six months ended June 30, 2005 because the Company did not adopt the optional recognition provisions of SFAS 123. Pro forma net loss including stock-based
compensation expense was $2,422 and $2,310 during the three and six months ended June 30, 2005. See Note 3 to the condensed consolidated financial statements for additional information.

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, 2005 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, 2005 included in its annual report on Form 10-K, as filed on March 10, 2006 with the SEC. The results of operations for the three and six months ended June 30, 2006 are not necessarily indicative of
the results to be expected for any future periods.

2. Significant Accounting Policies

The Companys significant accounting policies are disclosed in its audited consolidated financial statements for the year ended December 31,
2005.

Stock-Based Compensation  Effective January 1, 2006, the Company adopted the fair value recognition
provisions of Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS 123R) using the modified prospective application method. Accordingly, results for prior periods have not been
restated. Under the modified prospective application method, stock-based compensation expense for the three and six months ended June 30, 2006 includes compensation expense for stock-based awards granted by the Company as a public company prior
to, but not yet vested as of January 1, 2006, based on the grant-date fair value estimated in accordance with the original provision of SFAS No. 123, Accounting for Stock-Based Compensation (SFAS 123). For stock-based
awards granted before November 26, 2003 (the date on which the Company filed its registration statement for its initial public offering), the Company continues to amortize previously recorded deferred stock compensation expense following the
provisions of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees(APB 25). Stock-based compensation expense for all stock-based compensation awards granted after December 31, 2005 is
based on the grant-date fair value estimated in accordance with the provisions of SFAS 123R. The Company recognizes compensation costs for all stock-based compensation awards granted after December 31, 2005 on a straight line basis over the
requisite service period of the awards, which is generally the option vesting term of four to five years.

Prior to the adoption of SFAS 123R, the Company
recognized stock-based compensation expense in accordance with the provisions of APB 25 and complied with the disclosure provisions of SFAS 123, as amended by SFAS No. 148, Accounting for Stock-Based Compensation  Transition and
Disclosures (SFAS 148). The Company amortized 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 provided for
vesting of the overall awards at interim dates and resulted in accelerated expense recognition as compared to the straight-line method.

Net Income (Loss) per Share  Basic net income (loss) per share is computed by dividing the net income for the period by the weighted-average number of common shares outstanding during the period, less shares subject to
repurchase. Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted-average number of common shares and potentially dilutive common shares outstanding during the period. The dilutive effect of
outstanding options, warrants and restricted stock is reflected in dilutive earnings per share by application of the treasury stock method, which takes into consideration the unrecognized compensation cost as required by SFAS 123R.

Product Warranty  The Company generally provides a warranty on its products for a
period of one year, however, it may be longer 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):

Recent Accounting Pronouncement In July 2006, the Financial
Accounting Standards Board (FASB) issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an interpretation of FASB Statement No. 109 (FIN 48), which clarifies the accounting
for uncertainty in tax positions. FIN 48 requires that the Company recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The
provisions of FIN 48 are effective for fiscal years beginning after December 15, 2006. The Company is currently evaluating the impact that the adoption of FIN 48 will have on its consolidated financial statements.

3. Stock-Based Compensation

Stock-Based Compensation Plans

The Company has two Stock Incentive Plans: the 1998 Stock
Incentive Plan (the 1998 Plan) and the 2004 Stock Incentive Plan (the 2004 Plan). Upon completion of the Companys initial public offering in February 2004, the 1998 Plan was terminated and no shares are available for
future issuance under the 1998 Plan. Shares that are subject to options that expire, terminate or are cancelled, that are forfeited or as to which options have not been granted under the 1998 Plan will become available for issuance under the 2004
Plan.

The 2004 Plan, which became effective upon the completion of the Companys initial public offering in February 2004, provides
for the grant of options to purchase shares of common stock, restricted stock, stock appreciation rights and stock units. A total of 2,250,000 shares of common stock were originally authorized for issuance under the 2004 Plan. In addition to shares
that may from time to time be transferred from the 1998 Plan to the 2004 Plan reserve, an annual increase in the 2004 Plan reserve is added on the first day of each year. Initial hire-on stock options granted under the 2004 Plan are exercisable upon
vesting and generally vest 25% on the first anniversary of the grant date and then monthly thereafter over the remaining 36 months. Subsequent discretionary stock option grants generally vest equally each month over 48 months. Initial hire-on
options expire ten years from the date of grant while discretionary options granted subsequent to September 2005 generally expire five years from the date of grant.

The cost of restricted stock awards granted under the 2004 Plan, determined based on the fair market value of the shares at the date of grant, is expensed on a graded vesting method for grants issued prior to
January 1, 2006 and on a straight-line basis for restricted stock awards issued after December 31, 2005. At June 30, 2006, the Company had 61,500 shares of non-vested restricted stock outstanding.

The Company also has an Employee Stock Purchase Plan (ESPP) under which eligible employees may purchase shares of the Companys common
stock through periodic payroll deductions of up to 15% of total compensation at the lower of 85% of the fair market value of the of the common stock on either the first trading day of the offering period or on the last trading day of the purchase
period over a 24 month overlapping period, whichever is less. In April 2006, the Company amended its ESPP so that offering periods under the plan shall consist of consecutive six month periods instead of overlapping 24 month periods. The
Companys ESPP is considered compensatory under the provisions of SFAS 123R.

The Companys 1998 Plan, 2004 Plan and ESPP are
described more fully in the Companys 2005 Annual Report on Form 10-K and Form 8-K dated April 19, 2006.

Adoption of SFAS 123R

Effective January 1, 2006, the Company adopted SFAS 123R using the modified prospective application method. Accordingly, results for prior periods
have not been restated. Under the modified prospective application method, stock-based compensation expense for the three and six months ended June 30, 2006 includes compensation expense for stock-based awards granted by the Company as a public
company prior to, but not yet vested as of January 1, 2006, based on the grant-date fair value estimated in accordance with the original provision of SFAS 123. For stock-based awards granted before November 26, 2003 (the date on which the
Company filed its registration statement for its initial public offering), the Company continues to amortize deferred stock compensation expense following the provisions of APB 25. The Company recognizes these compensation costs for stock awards
granted prior to January 1, 2006 using the graded vesting method, and for stock awards granted after December 31, 2005 on a straight-line basis, over the requisite service period of the awards, which is generally the option vesting term of
four to five years. The graded vesting method provides for vesting of portions of the overall awards at interim dates and results in accelerated expense recognition as compared to the straight-line method. Stock-based compensation expense for all
stock-based compensation awards granted after December 31, 2005 is based on the grant-date fair value in accordance with the provisions of SFAS 123R.

Prior to the adoption of SFAS 123R, the Company recognized stock-based compensation expense in accordance with the provisions of APB 25 and provided the disclosures required by SFAS 123, as amended by SFAS 148.

Prior to the adoption of SFAS 123R, the Company presented all tax benefits of deductions resulting from the exercise of stock options as
operating cash flows in the Condensed Consolidated Statement of Cash Flows. In accordance with SFAS 123R, the cash flows resulting from excess tax benefits (tax deductions in excess of the stock-based compensation cost recognized for those options)
are classified as financing cash flows.

As a result of adopting SFAS 123R on January 1, 2006, the Companys net income for the
three and six months ended June 30, 2006 is approximately $2,254,000 (net of a tax benefit of $701,000) and $4,575,000 (net of a tax benefit of $1,084,000) lower than the net income the Company would have reported had it not adopted SFAS 123R.
The Companys basic and diluted net income per share for the three months ended June 30, 2006 are both approximately $0.04 lower than the earnings per share amounts the Company would have reported had it not adopted SFAS 123R. The
Companys basic and diluted net income per share for the six months ended June 30, 2006 is approximately $0.09 and $0.08 lower, respectively, than the earnings per share amounts the Company would have reported had it not adopted SFAS 123R.

Determining Fair Value

Valuation method  The Company estimates the fair value of stock options granted using the Black-Scholes valuation model.

Expected Term  The expected term represents the period that the Companys stock-based awards are expected to be outstanding. As the Company does not have sufficient historical experience for determining the expected term
of the stock option awards granted, the Company has based its expected term on the expected terms used by similar entities.

Expected
Volatility - 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 Black-Scholes valuation model assuming no volatility (minimum value method) to
estimate the fair value of options granted to employees. Options granted from November 26, 2003 to December 31, 2005 were valued using the Black-Scholes valuation model, with a volatility factor based on the average stock volatilities of
the Companys publicly traded competitors because the Company did not have a sufficient trading history. For the three and six months ended June 30, 2006, the Company estimated volatility based on considerations of the implied volatility
of long-term options traded on the open market and the average historical volatilities of similar entities.

Risk-Free Interest Rate
 The Company bases the risk-free interest rate used in the Black-Scholes valuation model on the implied yield currently available on the U.S. Treasury zero-coupon issues with an equivalent remaining term.

Expected Dividend - The expected dividend assumption is based on the Companys current expectations about its anticipated dividend policy.

The fair value of the Companys stock-based awards to employees was estimated using the following
weighted-average assumptions for the grants made in the three and six months ended June 30, 2006 and 2005:

As required by SFAS 123R, management has estimated expected forfeitures and is recognizing
compensation costs only for the stock-based awards expected to vest.

At June 30, 2006, the total compensation cost related to
unvested stock-based awards granted to employees under the Companys stock incentive plans but not yet recognized was approximately $24,008,000, net of estimated forfeitures of $3,116,000. This cost will be amortized on a graded vesting basis
for awards granted prior to January 1, 2006 and on a straight-line basis for awards granted after December 31, 2005 over a weighted-average period of approximately 2.7 years and will be adjusted for subsequent changes in estimated
forfeitures. Future option grants will increase the amount of compensation expense to be recorded in these periods.

The aggregate intrinsic value is calculated as the difference between the exercise price of the
underlying awards and the quoted price of our common stock for the 9,058,000 options that were in-the-money at June 30, 2006. During the three month and six month periods ended June 30, 2006, the aggregate intrinsic value of options
exercised under the Companys stock incentive plans was $13,598,000 and $32,911,000, respectively, determined as of the date of option exercise.

6. Income Taxes

The Companys tax expense for the three and six months ended June 30, 2006 is based on applying an expected annual effective tax rate of 28.5% to year-to-date pre-tax income. At March 31, 2006, the
Company reassessed the valuation allowance previously recorded against its net deferred tax assets which consisted primarily of net operating loss carryforwards and research and development tax credits. Based on the Companys projected future
taxable income, the Company determined that it is more likely than not that a portion of the deferred tax assets would be realized. Accordingly, during the quarter ended March 31, 2006, the Company released a portion of the valuation allowance
previously recorded against its deferred tax assets in the amount of $1,392,000.

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 chipset solutions that are manufacturable on low-cost, standard complementary metal-oxide
semiconductor, or CMOS, processes.

We provide a comprehensive portfolio of multi-chip and single chip products ranging from entry-level
wireless networking products for the home and small office markets to sophisticated wireless infrastructure systems-on-chip with advanced network management capabilities for the enterprise market. 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, wireless broadband, voice, mobile computing devices, and consumer electronics markets 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 and the draft 802.11n standard. We have a broad base of leading personal computer
original equipment manufacturer, or PC OEM, customers, including Acer, Apple, Fujitsu, NEC, and Toshiba and networking equipment manufacturers, including 2Wire, Belkin, Cisco Systems, D-Link, Linksys, NEC AT, NETGEAR, Siemens and TP Link and other
consumer electronics customers.

In addition, since June 2005 we have been shipping our cellular solution for Personal Access Systems, or
PAS, also referred to as Personal Handyphone Systems, or PHS, consisting of a single chip that implements a complete cellular transceiver, baseband, application processor, audio paths, power management, keyboard, speaker and display interfaces.
PAS/PHS, which is widely deployed in China, Japan and Taiwan, is an advanced Time Division Multiple Access-Time Division Duplex, or TDMA-TDD, technology operating at 1.9 GHz providing high quality voice, advanced data services and long battery life.
Our initial customer for our PAS products is UTStarcom, Inc.

Revenue. Our revenue is derived primarily from the sale of WLAN
chipset products, PAS chip solutions and, to a lesser extent, from licensed software and services. 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 handsets and integrated circuit card products. Some OEMs purchase chipsets directly 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 usually provides 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.

We provide customer incentives to some of our direct and indirect customers. These obligations are
estimated and recorded as a reduction of revenue at the time at which we ship product to the customers. Estimating incentive amounts requires that we make estimates regarding the percentage of committed incentives that will be submitted by our
customers and the value of the incentives at the time of redemption. These estimates may require revisions at later dates if the actual sales data submitted by the customers differs significantly from the original estimates, which may have the
effect of increasing or decreasing net revenue in particular periods.

In the six months ended June 30, 2006, Hon-Hai Precision
Industry Co., Ltd., UTStarcom, Inc., Cameo Communications, Inc. and Askey Computer Corporation accounted for 15%, 12%, 11% and 11% of our net revenue, respectively. In the six months ended June 30, 2005, Cameo Communications, Inc., Alpha
Networks, Inc, Hon-Hai Precision Industry Co., Ltd. and Askey Computer Corporation accounted for 17%, 15%, 15% and 11% of our net revenue, respectively. We expect to continue to have major concentrations of sales to a relatively small number of ODM
and OEM customers.

Substantially all of our sales are to customers outside the United States and Canada. Sales to customers in Asia
accounted for 98% and 95% of net revenue in the six months ended June 30, 2006 and 2005, respectively. 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 writedowns to state inventory
at the lower of cost or market caused by product obsolescence and 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, assembly and test costs are subject to changes based on the cyclical demand for semiconductors. In addition, after we purchase wafers from foundries, we also bear the yield risk related to
manufacturing these wafers into finished goods.

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 costs, regulatory testing costs, depreciation expense and allocated occupancy costs. All research and development costs are expensed as incurred. We expect our research and development costs to increase in
absolute dollars in the future as we invest to develop new products to be competitive and address new markets 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, depreciation and allocated occupancy costs. We expect sales and marketing expenses will decrease in absolute dollars in the third quarter as there were certain one-time discrete items, including certain amounts related
to sales commissions to independent sales representatives, travel expenses and recruiting costs, that were incurred during this quarter that we anticipate will not recur.

General and Administrative. General and administrative expense relates primarily to compensation and associated costs for general and administrative personnel, professional fees and banking fees, charges
related to allowance for doubtful accounts and allocated occupancy costs. We expect that general and administrative expenses will decrease in absolute dollars in the third quarter as we anticipate that a portion of the professional fees that were
incurred during this quarter will not recur.

Interest Income and Expense. Interest income consists of interest earned on cash
and cash equivalents and marketable securities balances.

Provision for Income Taxes. We make certain estimates and judgments
in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expense for
tax and financial statement purposes and the realizability of assets in future years.

We continually assess the likelihood that we will be
able to recover our deferred tax assets. We consider all available evidence, both positive and negative, including historical levels of income, projections of future income, expectations and risks associated with estimates of future taxable income,
and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. If recovery is not assessed as being more likely than not, we would increase our provision for taxes by recording a valuation allowance
against the deferred tax assets that will not ultimately be recoverable.

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 U.S. generally accepted accounting principles. 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.

Revenue Recognition. We derive revenue primarily from the sale of our wireless chipsets and reference designs. We recognize revenue in
accordance with SEC Staff Accounting Bulletin, or SAB, No. 104, Revenue Recognition. SAB No. 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
obligations are estimated and 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 us and our customers. Estimating incentive amounts requires that we make
estimates regarding the percentage of committed incentives that will be submitted by our customers and the value of the incentives at the time of redemption. These estimates may require revisions at later dates if the actual claims submitted by the
customers differ significantly from the original estimates, which may have the effect of increasing or decreasing net revenue and gross profit as a percentage of revenue in a particular period.

Inventory Valuation. 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 inventory 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-Based Compensation. Prior to January 1, 2006,
we elected to follow the intrinsic value-based method prescribed by Accounting Principles Board Opinion 25, Accounting for Stock Issued to Employees, or APB 25, and related interpretations in accounting for employee stock options rather than
adopting the alternative fair value accounting provided under Statement of Financial Accounting Standards, or SFAS, No. 123, Accounting for Stock Based Compensation. Therefore, we did not record any compensation expense for stock options
we granted to our employees where the exercise price equaled 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 were fixed. We complied with the
disclosure requirements of SFAS No. 123 and SFAS No. 148, Accounting for Stock-Based Compensation  Transition and Disclosures, 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.

Effective January 1, 2006 we adopted the fair value recognition provisions
of SFAS No. 123 (revised 2004), Share-Based Payment, or SFAS 123R, using the modified prospective application method. Under the modified prospective application method, compensation expense for stock-based awards granted by us as a
public company prior to, but not yet vested as of January 1, 2006, is based on the grant-date fair value estimated in accordance with the original provision of SFAS No. 123, Accounting for Stock-Based Compensation, or SFAS 123. For
stock-based awards granted before November 26, 2003 (the date on which we filed our registration statement for our initial public offering), we continue to record compensation expense following the provisions of APB 25. Stock-based compensation
expense for all stock-based compensation awards granted after December 31, 2005 is based on the grant-date fair value estimated in accordance with the provisions of SFAS 123R. Results for prior periods have not been restated. At June 30,
2006 there was $27.1 million of total unrecognized compensation cost related to non-vested compensation arrangements granted under all equity compensation plans. We expect to recognize that cost over a weighted average period of 2.7 years.



16



---

We estimate the fair value of options granted using the Black-Sholes option valuation model and the
assumptions used shown in Note 3 to the condensed consolidated financial statements. We estimate the expected term of options based on the expected terms of similar entities since we do not have sufficient historical experience for determining the
expected term of our stock option awards. We estimate the volatility of our common stock at the date of grant based on considerations of the implied volatility of long-term options traded on the open market and the average historical volatilities of
similar entities since we do not have sufficient historical volatility to be able to make that determination.

Allowance for Doubtful
Accounts. 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. 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 Reserve.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.

Income Taxes.We account for income taxes under the asset and liability approach. We record a valuation
allowance to reduce our net deferred tax assets to the amount that we believe is more likely than not to be realized. In assessing the need for a valuation allowance, we consider historical levels of income, projections of future income,
expectations and risks associated with estimates of future taxable income, and ongoing prudent and practical tax planning strategies. To the extent we believe it is more likely than not that some portion of our deferred tax assets will not be
realized, we would increase the valuation allowance against the deferred tax assets. Realization of our deferred tax assets is dependent primarily upon future U.S. taxable income. Our judgments regarding future profitability may change due to future
market conditions, changes in U.S. or international tax laws and other factors. These changes, if any, may require possible material adjustments to these deferred tax assets, resulting in a reduction in net income or an increase in net loss in the
period when such determinations are made.

The increase in net revenue for the three and six months ended June 30, 2006 as compared to
the same periods in 2005 was due to the increased volume of chipsets shipped as a result of further acceptance of our wireless chipset products, additional market demand for wireless networking products and the increased demand for our cellular
solution for PAS products. The total number of chipsets shipped increased from approximately 5.7 million in the second quarter of 2005 to approximately 11.2 million in the second quarter of 2006. The increase in chipsets shipped was
partially offset by a decrease in the average selling price of 14% as we competitively priced our chipsets to aggressively pursue market share. Additionally, our single chipset solutions, which have increased as a percentage of total chipsets
shipped, are generally priced lower than the combined average selling prices of our multi-chip solutions.

Gross profit as a percentage of revenue in the three and six months ended June 30, 2006
increased as compared to gross profit as a percentage of revenue in the comparable periods of 2005 primarily as a result of a greater concentration of higher margin products as a percentage of our total product mix, partially offset by a decline in
the overall blended average selling prices of our products from $7.61 in the second quarter of 2005 to $6.51 in the second quarter of 2006. We expect our gross margins will decrease in the third fiscal quarter of 2006 based on anticipated changes in
the product mix.

The increase in research and development expenses during the three months ended June 30,
2006, as compared to the three months ended June 30, 2005, was partly due to an increase in compensation-related costs of $2,117,000, due to a 36% increase in the number of employees engaged in research and development activities, and partly
due to costs related to stock-based compensation, which increased by $1,333,000 due to the adoption of SFAS 123R. In addition, there were increases in costs related to prototype parts and mask sets totaling $1,346,000, primarily resulting from
increased chip development efforts for new and existing markets and to further expand our revenue base in future periods.

The increase in
research and development expenses during the six months ended June 30, 2006, as compared to the six months ended June 30, 2005, was partly due to an increase in compensation-related costs of $3,596,000, due to a 29% increase in the number
of employees engaged in research and development activities, and partly due to costs related to stock-based compensation, which increased by $2,855,000 due to the adoption of SFAS 123R. In addition, there were increases in costs related to prototype
parts, mask sets, equipment and outside services of $2,254,000, primarily resulting from increased chip development efforts for new and existing markets and to further expand our revenue base in future periods.

The increase in sales and marketing expenses during the three months ended June 30, 2006, as
compared to the corresponding period in 2005, was partly due to an increase in compensation-related costs of $1,108,000, attributable to a 45% increase in the number of employees engaged in sales and marketing activities, and partly due to costs
related to stock-based compensation, which increased by $795,000 due to the adoption of SFAS 123R. In addition, there was an increase in travel expenses of $261,000 resulting from the increase in the number of employees, partially offset by a
decrease of $229,000 related to reduced tradeshow activity.

The increase in sales and marketing expenses during the six months ended
June 30, 2006, as compared to the corresponding period in 2005, was partly due to an increase in compensation-related costs of $2,104,000, attributable to a 45% increase in the number of employees engaged in sales and marketing activities, and
partly due to costs related to stock-based compensation, which increased by $1,384,000 due to the adoption of SFAS 123R. In addition, there was an increase in travel expenses of $399,000 resulting from the increase in the number of employees.

The increase in general and administrative expenses during the three months ended June 30,
2006, as compared to the corresponding period in 2005, was partly due to an increase in compensation-related costs of $455,000, primarily attributable to a 26% increase in the number of employees engaged in general and administrative activities, and
partly due to costs related to stock-based compensation of $430,000 resulting from the adoption of SFAS 123R. In addition, professional fees increased by $202,000.

The increase in general and administrative expenses during the six months ended June 30, 2006, as compared to the corresponding period in 2005, was partly due to an increase in compensation-related costs of
$796,000, primarily attributable to a 32% increase in the number of employees engaged in general and administrative activities, and partly due to costs related to stock-based compensation of $746,000 due to the adoption of SFAS 123R. In addition,
professional fees increased by $237,000.

During the three and six months ended June 30, 2006 we experienced increased interest income
as compared to the same periods in 2005, primarily due to a $34.0 million increase in cash, cash equivalents and marketable securities, resulting primarily from working capital generated from operations. In addition, yields achieved on our
investment portfolio have increased in the three and six months ended June 30, 2006 over the same period in 2005.

Our tax expense for the three months ended June 30, 2006 is $2,742,000, which is based on our
estimated annual effective tax rate of 28.5%. Our annual effective tax rate for 2006 differs from the fiscal 2005 rate and the U.S. statutory rate primarily due to the realization of previously reserved deferred tax assets such as net operating loss
carryforwards and credits. The 2005 tax expense related primarily to foreign taxes.

Our tax expense for the six months ended June 30,
2006 is $3,088,000, which is based on our estimated annual effective tax rate of 28.5% applied to year-to-date pretax income, less one-time tax benefits of $1,392,000 in the quarter ended March 31, 2006 related to the partial release of our
valuation allowance on deferred tax assets. Our annual effective tax rate for 2006 differs from the the fiscal 2005 rate and the U.S. statutory rate primarily due to the realization of previously reserved deferred tax assets such as net operating
loss carryforwards and credits. Our annual effective tax rate for 2005 differs from the U.S. statutory rate due to the realization of net operating loss carryforwards.

We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise
from differences in the timing of recognition of revenue and expense for tax and financial statement purposes and the realizability of assets in future years.

We continually assess the likelihood that we will be able to recover our deferred tax assets. We consider all available evidence, both positive and negative, including historical levels of income, projections of
future income, expectations and risks associated with estimates of future taxable income, and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If recovery is not likely, we would increase our
provision for taxes by recording a valuation allowance against the deferred tax assets that we estimate will not ultimately be recoverable.

Liquidity and Capital Resources

Our principal sources of liquidity as of June 30, 2006, consisted of cash, cash equivalents and marketable securities of $198.1 million, and our revolving credit facility, under which $10.0 million was available
to borrow. We anticipate that we will issue a standby letter of credit for $1.4 million that will reduce the amount available to borrow from $10.0 million to $8.6 million.

Operating Activities. Our operating activities provided $15.9 million of cash for the six months ended June 30, 2006 compared to $10.0
million for the six months ended June 30, 2005. Cash flow from operating activities for the six months ended June 30, 2006 resulted from net income of $13.6 million, an increase in accounts payable of $9.2 million related to increases in
inventory and timing of vendor payments and an increase in other accrued liabilities of $3.1 million primarily related to an increase in rebates, partially offset by an increase in inventory of $9.5 million due to an inventory rise to meet an
expected increase in demand and an increase in accounts receivable of $7.0 million due to increased revenue and timing of customer payments. Cash flow from operating activities for the six months ended June 30, 2005 resulted from net income of
$1.5 million, an increase in our accounts payable balance of $5.8 million due to the timing of payments for inventory, a decrease in accounts receivable of $2.6 million due to the timing of collections from our customers, an increase in other
accrued liabilities of $1.3 million primarily related to commissions to independent sales representatives and an increase in deferred revenue of $870,000 due to additional customer agreements signed during the period requiring partial upfront
payments, partially offset by an increase in our inventory by $2.9 million, due to inventory growth to meet increased demand.

Investing
Activities. Our investing activities used $11.2 million in the six months ended June 30, 2006, and provided $15.0 million in the six months ended June 30, 2005. Our investing activities primarily consisted of the purchase and
maturities of marketable securities and purchases of property and equipment.

Capital expenditures were $2.7 million and $2.8 million for
the six months ended June 30, 2006 and 2005, respectively. The capital expenditures within the six months period ended June 30, 2006 primarily consisted of computer and test equipment purchases. The capital expenditures within the six
months period ended June 30, 2005 primarily consisted of leasehold improvements for our new corporate headquarters and 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 $11.2 million and $2.7 million in the six months ended
June 30, 2006 and 2005, respectively. The cash provided in these periods primarily related to the issuance of common stock under our employee stock option plans. Our net cash provided by financing activities during the six months ended
June 30, 2006 also included excess tax benefits from stock-based compensation.

We expect to experience an increase in our operating
expenses in absolute dollars, particularly in research and development, 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.

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. On April 24, 2006 we signed a definitive agreement to acquire ZyDAS Technology Corporation, or ZyDAS. Under the terms of the agreement, we will issue a combination of $17.0 million in cash and
shares of our common stock, valued at approximately $6.7 million at the time of announcement. In addition, we will issue a combination of $1,000,000 in cash and 70,000 restricted shares of our common stock valued at approximately $1,900,000 at the
time of announcement as guaranteed additional amounts to ZyDAS employees. There may be additional consideration payable to the stockholders of ZyDAS if certain defined milestones are achieved. We may also enter into arrangements in the future with
respect to potential investments in, or acquisitions of, complementary businesses, products or technologies, which could 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.

and Analysis of Results of Operations and Financial Condition of our Form 10-K filed with the SEC on March 10, 2006. There have been no significant changes to our contractual obligations since we filed such Form 10-K.

As of June 30, 2006, 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 July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an interpretation of FASB Statement No. 109, or FIN
48, which clarifies the accounting for uncertainty in tax positions. FIN 48 requires that we recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits, that the position will be
sustained upon examination. The provisions of FIN 48 are effective for fiscal years beginning after December 15, 2006. We are currently evaluating the impact the adoption of FIN 48 will have on our consolidated financial statements.

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 the fair value of our investment portfolio or on our interest income. As of June 30, 2006, our investments were in money market funds, commercial paper, corporate notes, corporate bonds, 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 June 30, 2006, no balances were
outstanding under the revolving credit facility. However, we anticipate that we will issue a standby letter of credit for $1.4 million which will reduce the amount available to borrow from $10.0 million to $8.6 million. The line of credit bears
interest at the banks prime rate. We do not believe that a 10% change in the prime rate would have a significant impact on our interest expense.

We do not currently engage in foreign currency hedging transactions and as a result we have relatively little exposure to foreign currency exchange rate risk.

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 the 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.

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, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

(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 1A.Risk Factors

The following risk factors represent material
changes from the risk factors set forth in our Annual Report on Form 10-K for the year ended December 31, 2005, filed with the Securities and Exchange Commission, and should be read in conjunction with such risk factors. The risks and
uncertainties described below and in the Form 10-K are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe are immaterial may also affect our business. If any of these known or unknown
risks or uncertainties actually occurs and have material adverse effects on Atheros, our business, financial condition and results of operations could be seriously harmed.

If we fail to appropriately scale our operations in response to changes in demand for our existing products or for new products requested by our customers, our business could be materially and adversely
affected.

We have significantly grown and expanded our operations in a short period of time, and to achieve our business
objectives, we expect to continue to grow. Through internal growth, we have significantly increased the scope of our operations and expanded our workforce, from 260 employees as of December 31, 2004, to 327 employees as of December 31,
2005, and to 420 employees as of June 30, 2006. We anticipate that we will further expand our workforce through internal growth as well as acquisitions, including the ZyDAS transaction which we expect to complete in the third quarter of 2006.
Nonetheless, we may not be able to expand our workforce and operations in a sufficiently timely manner to respond effectively to changes in demand for our current and future products and services. In that event, we may be unable to meet competitive
challenges or exploit potential market opportunities, and our current or future business could be materially and adversely affected. Conversely, if we expand our operations and workforce too rapidly in anticipation of increased demand for our
products, and such demand does not materialize at the pace at which we expect, the rate of increase in our operating expenses may exceed the rate of increase in our revenue, which would adversely affect our operating results.

Our past growth has placed, and any future growth is expected to continue to place, a significant strain on our management personnel, systems and
resources. To implement our current business and product plans, we will need to continue to expand, train, manage and motivate our workforce. All of these endeavors will require substantial management effort. We anticipate that we will need to
implement a variety of new and upgraded operational and financial systems, as well as additional procedures and other internal management systems. These processes can be time consuming and expensive, increase management responsibilities, and divert
management attention.

In addition, we anticipate the need to lease additional office space in Northern California and other locations in
the near future to accommodate our growth, and we may also be required to relocate our employees from time to time. Such relocation could result in temporary disruptions of our operations or a diversion of our managements attention and
resources. If we are unable to effectively manage our expanding operations, we may be unable to scale our business quickly enough to meet competitive challenges or exploit potential market opportunities, or conversely, we may scale our business too
quickly and the rate of increase in our expenses may exceed the rate of increase in our revenue, either of which would materially and adversely affect our current or future business.

Our products typically have lengthy sales cycles. A customer may decide to cancel or change its product plans,
which could cause us to lose anticipated sales. In addition, our average product life cycles tend to be short and, as a result, we may hold excess or obsolete inventory that could adversely affect our operating results.

After we have developed and delivered a product to a customer, the customer will usually evaluate our product prior to designing its own equipment to
incorporate our product. Our customers may need several months to test, evaluate and choose whether to adopt our product, and to begin volume production of equipment that incorporates our product. Due to this lengthy sales cycle, we may experience
significant delays from the time we increase our operating expenses and make investments in inventory until the time that we generate revenue from these products. It is possible that we may never generate any revenue from these products after
incurring such expenditures. Even if a customer selects our product to incorporate into its equipment, we have no assurances that the customer will ultimately market and sell its equipment or that such efforts by our customer will be successful. The
delays inherent in our lengthy sales cycle also increase the risk that a customer will decide to cancel or curtail, reduce or delay its product plans. Such a cancellation or change in plans by a customer could cause us to lose sales that we had
anticipated.

While our sales cycles can be long, our average product life cycles tend to be short as a result of the rapidly changing
technology environment in which we operate. As a result, the resources devoted to product sales and marketing may not generate material revenue for us, and from time to time, we may need to write off excess and obsolete inventory. If we incur
significant marketing expenses and investments in inventory in the future that we are not able to recover, and we are not able to compensate for those expenses, our operating results could be adversely affected. In addition, if we sell our products
at reduced prices in anticipation of cost reductions but still hold higher cost products in inventory, our operating results would be harmed.

We may not be able to successfully integrate ZyDAS Technology Corporation or any other businesses that we may choose to acquire, and any acquisitions could harm our operating results and share price.

During the third quarter of 2006, we expect to complete the acquisition of ZyDAS, a privately held Taiwan-based fabless IC design company. In the future
we may make additional acquisitions of, and investments in, businesses that may offer complementary products and technologies, augment our market segment coverage, or enhance our technological capabilities, if appropriate opportunities arise. Risks
arising from the ZyDAS acquisition or other acquisitions or investments that could have a material adverse effect on our business, results of operations or financial condition include among other things:



| |  | the risk that we have not accurately assessed the business and prospects of an acquisition or the anticipated benefits of an acquisition,
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  | the difficulty or inability of completing the development and application of the acquired technology or products or of integrating that technology with our own,
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the difficulty of assimilating the operations and personnel of acquired businesses,
|- |  | -----------------------------------------------------------------------------------



| |  | the potential disruption of our ongoing business,
|- |  | -------------------------------------------------



| |  | the distraction of management and employees from our business,
|- |  | --------------------------------------------------------------



| |  | the risk of entering a geographic or business market in which we have little or no prior experience,
|- |  | ----------------------------------------------------------------------------------------------------



| |  | the difficulty of establishing and maintaining uniform standards, controls, policies and procedures,
|- |  | ----------------------------------------------------------------------------------------------------



| |  | the risk that there could be deficiencies in the internal control of any acquired company that could result in a material weakness in our overall internal control,
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the potential for unanticipated costs, expenditures and liabilities,
|- |  | --------------------------------------------------------------------



| |  | the potential for incurring amortization expenses or impairment charges if an acquisition results in significant goodwill or other intangible assets,
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the potential for changing relationships with customers, suppliers or contractual, intellectual property or employment issues, including the potential loss of key employees, and
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | the potential for dilution if we pay for the transaction with equity securities.
|- |  | --------------------------------------------------------------------------------



24



---

ZyDAS and any future acquisitions could result in additional dilutive issuances of equity securities,
one-time charges, the incurrence of debt or contingent liabilities, adverse tax consequences, deferred compensation charges, dilution to future earnings and amortization of amounts related to deferred compensation and certain purchased intangible
assets and large and immediate write-offs, any of which could negatively impact our results of operations and could cause our stock price to decline. We cannot be assured that we will be able to identify suitable acquisition opportunities or that we
will be able to consummate any such transactions or relationships on terms and conditions that are acceptable to us, that such transactions or relationships will be successful or that we will achieve the anticipated benefits of the acquisition.

We depend on key personnel 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 our senior
management, including our President and Chief Executive Officer and our senior engineering personnel. 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 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.

Equity awards
generally comprise a significant portion of our compensation packages for all employees. As a result of the applicability of SFAS 123R requirement to expense the fair value of stock options awarded to employees, we may need to modify our
compensation policies by, for example, increasing cash compensation to certain employees and/or instituting awards of restricted stock units, while simultaneously reducing awards of stock options. This modification of our compensation policies and
the applicability of the SFAS 123R requirement to expense the fair value of stock options awarded to employees would increase our operating expenses. We cannot be certain that any such potential changes in our compensation policies, if enacted,
would improve our ability to attract, retain and motivate employees. Our potential inability to attract and retain additional key employees and the increase in stock-based compensation expense could each have an adverse effect on our business,
financial conditional and results of operations.
