1. SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The condensed consolidated financial statements, other than the condensed consolidated balance sheet as of December 28, 2002, included herein are unaudited; however, they contain all normal recurring accruals and adjustments which, in the opinion of management, are necessary to present fairly the condensed consolidated financial position of Silicon Laboratories Inc. and its subsidiaries (collectively, the “Company”) at June 28, 2003, the condensed consolidated results of its operations for the three and six months ended June 28, 2003 and June 29, 2002 and the condensed consolidated statements of cash flows for the six months ended June 28, 2003 and June 29, 2002. All intercompany accounts and transactions have been eliminated. The condensed consolidated results of operations for the three and six months ended June 28, 2003 are not necessarily indicative of the results to be expected for the full year.

The accompanying unaudited condensed consolidated financial statements do not include certain footnotes and financial presentations normally required under accounting principles generally accepted in the United States. Therefore, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 28, 2002, included in the Company’s Form 10-K filed with the Securities and Exchange Commission (SEC) on January 22, 2003.

INVENTORIES

Inventories are stated at the lower of cost, determined using the first-in, first-out method, or market. Inventories consist of the following (in thousands):

	JUNE 28, 2003		DECEMBER 28, 2002
Work in progress	$	8,095	$	7,291
Finished goods	5,480		6,028
	$	13,575	$	13,319

OTHER COMPREHENSIVE INCOME

There were no material differences between net income and comprehensive income during any of the periods presented.

RECENT ACCOUNTING PRONOUNCEMENTS

In January 2003, the Financial Accounting Standards Board (FASB) issued Interpretation No. 46 (FIN 46), CONSOLIDATION OF VARIABLE INTEREST ENTITIES. FIN 46 requires that if an entity has a controlling financial interest in a variable interest entity, the assets, liabilities and results of activities of the variable interest entity should be included in the consolidated financial statements of the entity. FIN 46 is effective immediately for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period beginning after June 15, 2003. The Company does not believe that the adoption of FIN 46 will have a material impact on its results of operations or financial position.

In April 2003, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 149, AMENDMENT OF STATEMENT 133 ON DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. SFAS 149 amends SFAS No. 133 to provide clarification on the financial accounting and reporting of derivative instruments and hedging activities and requires that contracts with similar characteristics be accounted for on a comparable basis. The provisions of SFAS 149 are effective for contracts entered into or modified after June 30, 2003, and for hedging relationships designated after June 30, 2003. The Company does not believe that the adoption of SFAS 149 will have a material impact on its results of operations or financial position.

(UNAUDITED)

In May 2003, the FASB issued SFAS No. 150, ACCOUNTING FOR CERTAIN FINANCIAL INSTRUMENTS WITH CHARACTERISTICS OF BOTH LIABILITIES AND EQUITY. SFAS 150 establishes standards on the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. The provisions of SFAS 150 are effective for financial instruments entered into or modified after May 31, 2003 and to all other instruments that exist as of the beginning of the first interim financial reporting period beginning after June 15, 2003. The Company does not believe that the adoption of SFAS 150 will have a material impact on the Company’s results of operations or financial position.

4. COMMITMENTS AND CONTINGENCIES

On August 7, 2001, TDK Semiconductor Corporation (TDK) commenced a lawsuit against the Company for alleged willful infringement by its direct access arrangement (DAA) products of a TDK-held patent. On April 1, 2003, the Company settled the patent infringement lawsuit brought against the Company by TDK. Under the terms of the settlement agreement, TDK agreed to release all claims covered by the lawsuit. In addition, TDK granted to the Company irrevocable, royalty free licenses for the patent covered by the lawsuit and certain other related patents. In exchange, the Company agreed to make a one-time payment of $17 million to TDK in April 2003 and release all counterclaims covered by the lawsuit. Based on a valuation study performed by an independent appraiser, the Company recorded $15.3 million of the settlement amount as an expense during the first quarter of fiscal 2003 and the remaining $1.7 million was recorded as an intangible asset during the second quarter of fiscal 2003 for the value associated with the licensed patents and is being amortized over the remaining life of the technology.

October 9, 2002 dismissed without prejudice numerous individual defendants, including the four officers of our company who had been named individually. On February 19, 2003, the Court denied the motion to dismiss the complaint against the Company. The plaintiff class has proposed a Memorandum of Understanding (“MOU”) and related agreements which set forth the terms of a proposed settlement between the plaintiff class and the Company and the other approximately 300 defendants. It is anticipated that any potential financial obligation of the Company to plaintiffs due pursuant to the terms of the MOU and related agreements would be covered by existing insurance. Therefore, the Company does not expect that the proposed settlement would involve any payment by the Company. The MOU and related agreements are subject to a number of contingencies, including the approval of the MOU by a sufficient number of the other approximately 300 defendants, the negotiation of a final settlement agreement, and approval of the settlement by the court. The Company cannot be certain as to whether or when a settlement will occur or be finalized and is unable at this time to determine whether the outcome of the litigation will have a material impact on its results of operations or financial condition in any future period.

The Company is involved in various other legal proceedings that have arisen in the normal course of business. While the ultimate results of these matters cannot be predicted with certainty, management does not expect them to have a material adverse effect on the consolidated financial position or results of operations.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THE FOLLOWING DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS SHOULD BE READ IN CONJUNCTION WITH THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES THERETO INCLUDED ELSEWHERE IN THIS REPORT ON FORM 10-Q. THIS DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS. PLEASE SEE THE “CAUTIONARY STATEMENT” ABOVE AND “FACTORS AFFECTING OUR FUTURE OPERATING RESULTS” BELOW FOR A DISCUSSION OF THE UNCERTAINTIES, RISKS AND ASSUMPTIONS ASSOCIATED WITH THESE STATEMENTS. OUR FISCAL YEAR-END FINANCIAL REPORTING PERIODS ARE A 52- OR 53- WEEK YEAR ENDING ON THE SATURDAY CLOSEST TO DECEMBER 31ST. FISCAL YEAR 2003 WILL HAVE 53 WEEKS WITH THE EXTRA WEEK OCCURRING IN THE FOURTH QUARTER OF THIS YEAR. OUR SECOND QUARTER OF FISCAL YEAR 2003 ENDED JUNE 28, 2003. OUR SECOND QUARTER OF FISCAL YEAR 2002 ENDED JUNE 29, 2002. ALL OF THE QUARTERLY PERIODS REPORTED IN THIS QUARTERLY REPORT ON FORM 10-Q HAD THIRTEEN WEEKS.

OVERVIEW

We design and develop proprietary, analog-intensive, mixed-signal integrated circuits (ICs) for the communications industry. Our innovative ICs can dramatically reduce the cost, size and system power requirements of the products that our customers sell to consumers. We currently offer ICs that can be incorporated into communications devices, such as wireless phones and modems, as well as cable and satellite set-top boxes, residential communication gateways for cable or DSL, and optical network equipment. Customers during fiscal 2002 or the first six months of fiscal 2003 included Agere Systems, Ambit, Broadcom, Conexant, Echostar, Hughes Network Systems, Intel, Sagem, Samsung, Smart Link, Texas Instruments and Wavecom.

Our company was founded in 1996. Our business has grown rapidly since our inception, as reflected by our employee headcount, which increased to 412 at June 28, 2003, from 364 employees at the end of fiscal 2002 and 279 employees at the end of fiscal 2001. As a “fabless” semiconductor company, we rely on third-party semiconductor fabricators in Asia to manufacture the silicon wafers that reflect our IC designs. Each wafer contains numerous die, which are cut from the wafer to create a chip for an IC. We also rely on third-parties in Asia to assemble, package, and in some cases, test these die prior to shipment to our customers. We plan to increase the amount of testing performed by such third parties, which we anticipate will facilitate faster delivery of products to our customers (particularly those located in Asia), shorter production cycle times, lower inventory requirements, lower costs and increased flexibility of test capacity. We are also in the process of implementing supply chain management software which we believe will

improve our ability to scale our operations, reduce our inventory requirements and improve the quality of our shipment scheduling commitments with our customers through improved efficiency.

Our product portfolio has expanded from a single product in 1996 to nine distinct product families targeting the wireless, wireline and optical markets. Our expertise in analog-intensive, high-performance, mixed signal ICs enables us to develop highly differentiated solutions that address large markets. For example, our silicon DAA product family is optimized for the PC modem market; our ISOmodem™ family of embedded modems has been widely adopted by satellite set-top box manufacturers; and our Aero™ Global System for Mobile Communications (GSM)/General Packet Radio Services (GPRS) transceiver family is being shipped in cellular handsets worldwide. We continue to introduce next generation ICs with added functionality and further integration. During the first six months of fiscal 2003, we expanded our Aero Transceiver family with the launch of Aero I, a single package GSM/GPRS transceiver, and we introduced a new ISOmodem product that integrates our third generation silicon DAA. We plan to further diversify our product portfolio by introducing products that increase the amount of content we provide for existing applications and by introducing ICs for markets we do not currently address. We expect the addition of these new applications to expand our total available market opportunity.

Many of our end customers purchase products indirectly from us through distributors and contract manufacturers. An end customer purchasing through a contract manufacturer typically instructs such contract manufacturer to obtain our products and incorporate such products with other components for sale by such contract manufacturer to the end customer. Although we actually sell the products to, and are paid by, the distributors and contract manufacturers, we refer to such end customer as our customer. During the six months ended June 28, 2003, one end customer, Samsung, represented 21.7% of our revenues. No other single end customer accounted for more than 10% of our revenues during the six months ended June 28, 2003. Two of our distributors, Edom Technology and Uniquest, each selling products to several customers in Asia, represented 12.3% and 10.5% of our revenues during the six months ended June 28, 2003, respectively. No other distributor accounted for more than 10% of our revenues during the six months ended June 28, 2003.

The percentage of our revenues derived from customers located outside of the United States was 79% in fiscal 2002, 66% in fiscal 2001, and 21% in fiscal 2000. This percentage increase in the two most recent years reflects our progress in the areas of product and customer diversification, as many of our wireless, and increasingly, wireline customers manufacture and design their products in the Pacific Rim region. All of our revenues to date have been denominated in U.S. dollars. We believe that a large percentage of our revenues will continue to be derived from customers outside of the United States as our products receive acceptance in international markets.

The sales cycle for the test and evaluation of our ICs can range from one month to 12 months or more. An additional three to six months or more may be required before a customer ships a significant volume of devices that incorporate our ICs. Due to this lengthy sales cycle, we may experience a significant delay between incurring expenses for research and development and selling, general and administrative efforts, and the generation of corresponding sales, if any. Consequently, if sales in any quarter do not occur when expected, expenses and inventory levels could be disproportionately high, and our operating results for that quarter and, potentially, future quarters would be adversely affected. Moreover, the amount of time between initial research and development and commercialization of a product, if ever, can be substantially longer than the sales cycle for the product. Accordingly, if we incur substantial research and development costs without developing a commercially successful product, our operating results, as well as our growth prospects, could be adversely affected.

Rapid changes in our markets and across our product areas make it difficult for us to estimate the impact of seasonal factors on our business. Because many of our ICs are designed for use in consumer products such as personal computers (PCs) and wireless telephones, we expect that the demand for our products will be subject to seasonal demand resulting in increased sales in the third and fourth quarters of each year when customers place orders to meet holiday demand.

The following describes the line items set forth in our condensed consolidated statements of income:

REVENUES. Revenues are generated principally by sales of our ICs. We recognize revenue upon the transfer of title, which generally occurs upon shipment to our customers. Revenues are deferred on shipments to distributors until they are resold by such distributors to end customers. Our products typically carry a one-year replacement warranty. Replacements have been insignificant to date. Our revenues are subject to variation from period to period due to the volume of shipments made within a period and the prices we charge for our products. The vast majority of our revenues were negotiated at prices that reflect a discount from the list prices for our products. These discounts are made for a variety of reasons, including to establish a relationship with a new customer, as an incentive for customers to purchase products in larger volumes, to provide profit margin to our distributors who resell our products or in response to competition. In addition, as a product matures, we expect that the average selling price for such product will decline due to the greater availability of competing products. Our ability to increase revenues in the future is dependent on increased demand for our established products and our ability to ship larger volumes of those products in response to such demand, as well as our ability to develop new products and subsequently achieve customer acceptance of newly introduced products.

COST OF REVENUES. Cost of revenues includes the cost of purchasing finished silicon wafers processed by independent foundries; costs associated with assembly, test and shipping of those products; costs of personnel and equipment associated with manufacturing support, logistics and quality assurance; costs of software royalties and amortization of purchased software and other intellectual property license costs; an allocated portion of our occupancy costs; allocable depreciation of testing equipment and leasehold improvements; and in the first three months of fiscal 2003, the settlement costs associated with the TDK Semiconductor Corporation (TDK) patent infringement lawsuit. Generally, we depreciate equipment over four years on a straight line basis and leasehold improvements over the shorter of the estimated useful life or the applicable lease term. Recently introduced products tend to have higher cost of revenues per unit due to initially low production volumes required by our customers and higher costs associated with new package variations. Generally, as production volumes for a product increase, unit production costs tend to decrease as our yields improve and our semiconductor fabricators, assemblers and test operations achieve greater economies of scale for that product. Additionally, the cost of wafer procurement and assembly and test services, which are significant components of cost of goods sold, vary cyclically with overall demand for semiconductors and our suppliers’ available capacity of such products and services.

RESEARCH AND DEVELOPMENT. Research and development expense consists primarily of compensation and related costs of employees engaged in research and development activities, new product mask, wafer and packaging costs, external consulting and services costs, equipment tooling, as well as an allocated portion of our occupancy costs for such operations. We generally depreciate our research and development equipment over four years and amortize our purchased software from computer-aided design tool vendors over three to four years. Development activities include the design of new products and test methodologies to ensure compliance with required specifications.

SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative expense consists primarily of personnel-related expenses, related allocable portion of our occupancy costs, sales commissions to independent sales representatives, professional fees, directors’ and officers’ liability insurance, patent litigation legal fees, other promotional and marketing expenses, and reserves for bad debt. Write-offs of uncollectible accounts have been insignificant to date.

AMORTIZATION OF DEFERRED STOCK COMPENSATION. In connection with the grant of stock options and direct issuances of stock to our employees, we record deferred stock compensation, representing, for accounting purposes, the difference between the exercise price of option grants, or the issuance price of direct issuances of stock, as the case may be, and the fair value of our common stock at the time of such grants or issuances. The deferred stock compensation is amortized over the vesting period of the applicable options or shares, generally five to eight years. The amortization of deferred stock compensation is recorded as an operating expense.

INTEREST INCOME. Interest income reflects interest earned on average cash, cash equivalents and investment balances. We may from time to time elect to invest in tax-advantaged short-term investments yielding lower nominal interest proceeds.

INTEREST EXPENSE. Interest expense consists of interest on our long-term debt and capital lease obligations.

OTHER INCOME (EXPENSE). Other income (expense) reflects our share of losses in and impairment reserves related to our equity investment in ASIC Design Services, Inc. (ADS) and the gain on the disposal of fixed assets.

PROVISION FOR INCOME TAXES. We accrue a provision for federal and state income tax at the applicable statutory rates adjusted for non-deductible expenses, research and development tax credits and interest income from tax-advantaged short-term investments.

COMPARISON OF THE THREE AND SIX MONTHS ENDED JUNE 28, 2003 TO THE THREE AND SIX MONTHS ENDED JUNE 29, 2002.

REVENUES. Revenues for the three months ended June 28, 2003 were $69.1 million, an increase of $27.9 million, or 67.7%, from revenues of $41.2 million in the three months ended June 29, 2002. Revenues for the six months ended June 28, 2003 were $132.8 million, an increase of $62.8 million, or 89.7%, from revenues of $70.0 million in the six months ended June 29, 2002. The increase during the most recent quarter was primarily attributable to growth in the volume of sales for our ISOModems and silicon DAA products. The increase during the most recent six month period was primarily attributable to significant growth in the volume of sales for our wireless products, including the Aero Transceiver, reflecting a growing number of customers adopting these products into their offerings. During the first six months of fiscal 2003, we experienced normal decreases in the average selling prices, particularly with respect to our wireless products. However, these price decreases were more than offset by increases in sales volumes for our products and, to a lesser extent, the introduction of higher priced next generation products.

GROSS PROFIT. Gross profit for the three months ended June 28, 2003 was $38.8 million, or 56.2% of revenues, an increase of $16.9 million, as compared with gross profit of $21.9 million, or 53.1% of revenues, in the three months ended June 29, 2002. Gross

profit for the six months ended June 28, 2003 was $59.0 million, or 44.4% of revenues, an increase of $20.4 million, as compared with gross profit of $38.6 million, or 55.2% of revenues, in the six months ended June 29, 2002. The increase in gross profit dollars for the most recent quarter was primarily due to the substantial increase in sales volume. The increase in gross profit percentage during the most recent quarter was primarily due to a substantial increase in our sales volume, increased utilization of our internal test capacity and the use of lower cost subcontracted test services. While we expect periodic fluctuations, to the extent sales of our wireless products into the highly competitive GSM handset market comprise a larger percentage of our revenue, we expect to experience increased downward pressure on our average selling prices for such individual products. The increase in gross profit dollars for the most recent six month period was also primarily due to a substantial increase in sales volumes, but was offset to a large extent by the $15.3 million charge relating to the settlement of the patent infringement lawsuit filed against us by TDK. The decrease in gross profit percentage during the most recent six month period was primarily due to the charge related to the settlement of the patent infringement lawsuit but was partially offset due to the substantial increase in our sales volumes, increased utilization of our internal test capacity and the use of lower cost subcontracted test services.

RESEARCH AND DEVELOPMENT. Research and development expense for the three months ended June 28, 2003 was $11.6 million, or 16.8% of revenues, which reflected an increase of $3.4 million, or 41.7%, as compared with research and development expense of $8.2 million, or 19.9% of revenues, for the three months ended June 29, 2002. Research and development expense for the six months ended June 28, 2003 was $21.2 million, or 15.9% of revenues, which reflected an increase of $4.9 million, or 30.2%, as compared with research and development expense of $16.3 million, or 23.2% of revenues, for the six months ended June 29, 2002. The increase in the dollar amount of research and development expense for the recent three and six month periods was principally due to increased staffing and associated costs to pursue new product development opportunities. As a percentage of revenues, research and development expense decreased significantly due to the substantial increase in revenues during both the recent three and six months periods of fiscal 2003. We expect that research and development expense will increase in absolute dollars in future periods as we continue to increase our staffing and associated costs to pursue additional new product development opportunities, but will fluctuate as a percentage of revenues due to changes in sales volume and the timing of certain expensive items related to new product development initiatives, such as engineering mask and wafer costs.

SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative expense for the three months ended June 28, 2003 was $9.5 million, or 13.8% of revenues, which reflected an increase of $1.2 million, or 14.9%, as compared to selling, general and administrative expense of $8.3 million, or 20.2% of revenues, in the three months ended June 29, 2002. Selling, general and administrative expense for the six months ended June 28, 2003 was $ 19.5 million, or 14.7% of revenues, which reflected an increase of $4.5 million, or 30.5%, as compared to selling, general and administrative expense of $15.0 million, or 21.4% of revenues, in the six months ended June 29, 2002. The increase in the dollar amount of selling, general and administrative expense during the recent three and six month periods was principally attributable to increased staffing and associated costs, sales commissions associated with our higher revenues and transition of the Samsung account from a non-commission bearing distributor account to a commission bearing direct account serviced by a third-party sales representative, and the continued expansion of our sales and marketing infrastructure to support the higher sales volumes. These factors were offset in part by $0.5 million of negotiated savings relative to amounts previously accrued for legal costs in connection with the TDK litigation. We expect selling, general and administrative expense to continue to increase in absolute dollars in future periods as we continue to expand our sales channels, marketing efforts and administrative infrastructure. In addition, we expect selling, general and administrative expense to fluctuate as a percentage of revenues principally because of continued spending on infrastructure and personnel to provide sales and technical support to our foreign customers; fluctuating usage of advertising to promote our products and, in particular, our newly introduced products; and potential significant variability in our future sales volume.

AMORTIZATION OF DEFERRED STOCK COMPENSATION. We recorded deferred stock compensation for the difference between the exercise price of option grants or the issuance price of direct issuances of stock, as the case may be, and the fair value of our common stock at the time of such grants or issuances. We are amortizing this amount over the vesting periods of the applicable

options or restricted stock, which resulted in amortization expense of $1.2 million and $2.5 million for the three and six months ended June 28, 2003, respectively, as compared to $1.3 million and $ 2.6 million for the three and six months ended June 29, 2002, respectively.

INTEREST INCOME. Interest income for the three and six months ended June 28, 2003 was $0.3 million and $0.7 million, respectively, as compared to $0.4 million and $0.8 million for the three and six months ended June 29, 2002. This decrease was primarily due to lower interest rates on cash and short-term investments balances during the three and six months ended June 28, 2003.

INTEREST EXPENSE. Interest expense for the three and six months ended June 28, 2003 was zero, as compared to $0.1 million and $0.3 million for the three and six months ended June 29, 2002, respectively. The decrease in interest expense was due to the absence of debt and equipment financing during the recent three and six month periods.

OTHER INCOME (EXPENSE). Other expense in the three and six months ended June 28, 2003 was $0.1 million and $0.8 million, respectively, which primarily reflects our share of the losses in our investment in ADS and an impairment charge to write off our remaining investment balance in ADS as a result of our evaluation of the market viability associated with the product under development by ADS and our decision to not make any additional investments in ADS. We did not have any equity investments, and therefore no corresponding losses, during the three and six month periods ending June 29, 2002.

PROVISION FOR INCOME TAXES. Our tax provision rate, excluding the impact of the nondeductible amortization of deferred stock compensation, was 32% for the three and six months ended June 28, 2003, as compared to 29% for the three and six months ended June 29, 2002. Our favorable research and development tax credits and tax-advantaged interest income in the current year periods are lower in proportion to pretax income as compared to the prior year periods. Additionally, the non-deductibility of losses in our investment in ADS contributes to the increase in the tax provision rate in the current year periods. The tax provision rate differs from the statutory rate due to the impact of research and development tax credits, tax-exempt interest income, state taxes and other permanent items.

LIQUIDITY AND CAPITAL RESOURCES

Our principal sources of liquidity as of June 28, 2003 consisted of $131.2 million in cash, cash equivalents and short-term investments. Our short term investments consist primarily of obligations of municipalities and agencies of the U.S. government that have initial maturities of less than one year.

In addition, we have credit available under a bank credit facility with a revolving line of credit for borrowings and letters of credit of up to the lesser of $5.0 million or 80% of eligible accounts receivable at the bank’s prime lending rate, which was 4.0% as of June 28, 2003. At June 28, 2003, a letter of credit for $0.4 million related to a building lease was outstanding under the revolving line of credit and $4.6 million was available for new borrowings or letters of credit. The bank facility is secured by our accounts receivable, inventories, capital equipment and all other unsecured assets (excluding intellectual property). The line of credit prohibits the payment of cash dividends and requires the maintenance of tangible net worth and compliance with financial ratios that measure our immediate liquidity and our ongoing ability to pay back our outstanding obligations. We believe we were in compliance with all covenants at June 28, 2003.

Net cash provided by operating activities was $20.6 million during the six months ended June 28, 2003, compared to $10.4 million during the six months ended June 29, 2002. The increase was principally due to revenues generated by a higher volume of sales over a relatively fixed cost structure but was offset by a $15.3 million cash payment in the second quarter of 2003 relating to the settlement of patent litigation with TDK. Operating cash flows during the six months ended June 28, 2003 reflect our net income of $9.9 million, as adjusted for non-cash charges (depreciation and amortization and equity investment losses) of $11.5 million, and a net decrease in the non-cash components of our working capital of $0.8 million.

Net cash used in investing activities was $20.6 million during the six months ended June 28, 2003, compared to net cash used of $28.3 million during the six months ended June 29, 2002. The decrease was principally due to lower purchases of capital

equipment and lower net purchases of short-term investments during the most recent quarter. Investing cash flows during the six months ended June 28, 2003 reflect our net purchase of short-term investments of $11.5 million, capital expenditures of $4.0 million, and investment in other assets of $5.1 million.

We anticipate additional capital expenditures of approximately $8.8 million for fiscal 2003. Additionally, as part of our growth strategy, we expect to evaluate opportunities to invest in or acquire other business or technologies that would complement or expand our current offerings, expand the breadth of our markets or enhance our technical capabilities.

Net cash provided by financing activities was $4.4 million during the six months ended June 28, 2003, compared to net cash provided of $0.8 million during the six months ended June 29, 2002. The increase in cash flows from financing activities during the six months ended June 28, 2003 was principally due to proceeds from the exercise of employee stock options and purchases under our employee stock purchase plan.

Our future capital requirements will depend on many factors, including the rate of sales growth, market acceptance of our products, the timing and extent of research and development projects, and the expansion of our sales and marketing activities. We believe our existing cash balances and credit facility are sufficient to meet our capital requirements through at least the next 12 months, although we could be required, or could elect, to seek additional funding prior to that time. We may enter into acquisitions or strategic arrangements in the future which also could require us to seek additional equity or debt financing.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of financial statements and accompanying notes in conformity with accounting principles generally accepted in the United States requires that we make estimates and assumptions that affect the amounts reported. Changes in the facts and circumstances could have a significant impact on the resulting financial statements. We believe the following critical accounting policies affect our more complex judgments and estimates. We also have other policies that we consider to be key accounting policies, such as our policies for revenue recognition, including the deferral of revenues and gross profit on sales to distributors; however, these policies do not meet the definition of critical accounting estimates because they do not generally require us to make estimates or judgments that are difficult or subjective.

Allowance for doubtful accounts – We evaluate the collectibility of our accounts receivable based on a combination of factors. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us, we record a specific allowance to reduce the net receivable to the amount we reasonably believe will be collected. For all other customers, we recognize allowances for doubtful accounts based on a variety of factors including the length of time the receivables are past their contractual due date, the current business environment, and our historical experience. If the financial condition of our customers were to deteriorate or if economic conditions worsened, additional allowances may be required in the future. Accounts receivable write-offs to date have been minimal.

Inventory Valuation – We assess the recoverability of inventories through an on-going review of inventory levels in relation to sales history, backlog and forecasts, product marketing plans and product life cycles. To address the difficult, subjective and complex area of judgment in determining appropriate inventory valuation in a consistent manner, we apply a set of methods, assumptions and estimates to arrive at the net inventory amount by completing the following: First, we identify any inventory that has been previously reserved in prior periods. This inventory remains reserved until sold, destroyed or otherwise disposed of. Second, we examine the inventory line items that may have some form of obsolescence due to non-conformance with electrical and mechanical standards as identified by our quality assurance personnel and provide reserves. Third, the remaining inventory not otherwise identified to be reserved is compared to an assessment of product history and forecasted demand, typically over the last six months and next six months, or actual firm backlog on hand. Finally, the result of this methodology is compared against the product life cycle and competitive situations in the marketplace driving the outlook for the consumption of the inventory and the appropriateness of the

resulting inventory levels. Demand for our products may fluctuate significantly over time, and actual demand and market conditions may be more or less favorable than those that we project. In the event that actual demand is lower or market conditions are worse than originally projected, additional inventory write-downs may be required.

Impairment of long-lived assets – We review long-lived assets, including goodwill, fixed assets and purchased intangible assets, for impairment whenever changes in circumstances indicate that the carrying amount of the assets may not be recoverable and record an impairment charge if necessary. Such evaluations compare the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset and are significantly impacted by estimates of future prices and volumes for our products, capital needs, economic trends and other factors which are inherently difficult to forecast.

Income Taxes – We are required to estimate income taxes in each of the jurisdictions in which we operate. This process involves estimating the actual current tax liability together with assessing temporary differences in recognition of income (loss) for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheet. We must then assess the likelihood that the deferred tax assets will be recovered from future taxable income (loss) and, to the extent we believe that recovery is not likely, we must establish a valuation allowance against the deferred tax asset. We operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues, which may require an extended period of time to resolve and could result in additional assessments of income tax. In our opinion, adequate provisions for income taxes have been made for all years.

RECENT ACCOUNTING PRONOUNCEMENTS

In January 2003, the FASB issued Interpretation No. 46 (FIN 46), CONSOLIDATION OF VARIABLE INTEREST ENTITIES. FIN 46 requires that if an entity has a controlling financial interest in a variable interest entity, the assets, liabilities and results of activities of the variable interest entity should be included in the consolidated financial statements of the entity. FIN 46 is effective immediately for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period beginning after June 15, 2003. We do not believe that the adoption of FIN 46 will have a material impact on our results of operations or financial position.

In April 2003, the FASB issued SFAS No. 149, AMENDMENT OF STATEMENT 133 ON DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. SFAS 149 amends SFAS No. 133 to provide clarification on the financial accounting and reporting of derivative instruments and hedging activities and requires that contracts with similar characteristics be accounted for on a comparable basis. The provisions of SFAS 149 are effective for contracts entered into or modified after June 30, 2003, and for hedging relationships designated after June 30, 2003. We do not believe that the adoption of SFAS 149 will have a material impact on our results of operations or financial position.

In May 2003, the FASB issued SFAS No. 150, ACCOUNTING FOR CERTAIN FINANCIAL INSTRUMENTS WITH CHARACTERISTICS OF BOTH LIABILITIES AND EQUITY. SFAS 150 establishes standards on the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. The provisions of SFAS 150 are effective for financial instruments entered into or modified after May 31, 2003 and to all other instruments that exist as of the beginning of the first interim financial reporting period beginning after June 15, 2003. We do not believe that the adoption of SFAS 150 will have a material impact on our results of operations or financial position.

QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK

All of our investments are entered into for other than trading purposes. Our interest income is sensitive to changes in the general level of U.S. interest rates, particularly since the majority of our investments are in short-term instruments. Based on our investment holdings as of June 28, 2003, an immediate 1 percentage point decline in the yield for such instruments would decrease our annual

interest income by $1.3 million. We believe that our investment policy is conservative, both in terms of the average maturity of our investments and the credit quality of the investments we hold.

FACTORS AFFECTING OUR FUTURE OPERATING RESULTS

RISKS RELATED TO OUR BUSINESS

WE MAY NOT BE ABLE TO MAINTAIN OUR HISTORICAL GROWTH AND MAY EXPERIENCE SIGNIFICANT PERIOD-TO-PERIOD FLUCTUATIONS IN OUR REVENUES AND OPERATING RESULTS, WHICH MAY RESULT IN VOLATILITY IN OUR STOCK PRICE

Although we have experienced revenue growth in our nine most recent quarterly periods, we may not be able to sustain this growth. We may also experience significant period-to-period fluctuations in our revenues and operating results in the future due to a number of factors, and any such variations may cause our stock price to fluctuate. It is likely that in some future period our revenues or operating results will be below the expectations of public market analysts or investors. If this occurs, our stock price may drop, perhaps significantly.

A number of factors, in addition to those cited in other risk factors applicable to our business, may contribute to fluctuations in our revenues and operating results, including:

• the timing and volume of orders received from our customers;

• the rate of acceptance of our products by our customers, including the acceptance of new products we may develop for integration in the products manufactured by such customers, which we refer to as “design wins”;

• the time lag between “design wins” and production orders;

• the demand for, and life cycles of, the products incorporating our ICs;

• the rate of adoption of mixed-signal ICs in the markets we target;

• deferrals of customer orders in anticipation of new products or product enhancements from us or our competitors or other providers of ICs;

• changes in product mix;

• the average selling prices for our products could drop suddenly due to competitive offerings or competitive predatory pricing;

• impairment charges related to inventory, equipment or other long-lived assets;

• significant legal costs to defend our intellectual property rights or respond to claims against us; and

• the rate at which new markets emerge for products we are currently developing or for which our design expertise can be utilized to develop products for these new markets.

The markets for mobile telephones, personal computers, satellite television set-top boxes and voice over DSL applications are characterized by rapid fluctuations in demand and seasonality that result in corresponding fluctuations in the demand for our wireless and wireline products that are incorporated in such devices. Additionally, the rate of technology acceptance by our customers results in fluctuating demand for our products as customers are reluctant to incorporate a new IC into their products until the new IC has achieved market acceptance. Once a new IC achieves market acceptance, demand for the new IC can quickly accelerate to a point and then level off such that rapid historical growth in sales of a product should not be viewed as indicative of continued future growth. In addition, demand can quickly decline for a product when a new IC product is introduced and receives market acceptance. For example, transceivers that provide some of the functionality provided by our RF Synthesizers have been introduced to market by us and our competitors. The introduction of these competing transceivers, including our Aero Transceiver, has resulted in a rapid decline in our sales of RF Synthesizers. Due to the various factors mentioned above, the results of any prior quarterly or annual periods should not be relied upon as an indication of our future operating performance.

WE DEPEND ON A LIMITED NUMBER OF CUSTOMERS FOR A SUBSTANTIAL PORTION OF OUR REVENUES, AND THE LOSS OF, OR A SIGNIFICANT REDUCTION IN ORDERS FROM, ANY KEY CUSTOMER COULD SIGNIFICANTLY REDUCE OUR REVENUES

The loss of any of our key customers, or a significant reduction in sales to any one of them, would significantly reduce our revenues and adversely affect our business. During the six months ended June 28, 2003, our ten largest customers accounted for 67.8% of our revenues. We had one customer, Samsung, which represented 21.7% of our revenues. No other single customer accounted for more than 10% of our revenues during the six months ended June 28, 2003. Two distributors, Edom Technology and Uniquest, each selling to multiple customers in Asia, represented 12.3% and 10.5% of our revenues during the six months ended June 28, 2003, respectively. Most of the markets for our products are dominated by a small number of potential customers. Therefore, our operating results in the foreseeable future will continue to depend on our ability to affect sales to these dominant customers, as well as the ability of these customers to sell products that incorporate our IC products. In the future, these customers may decide not to purchase our ICs at all, purchase fewer ICs than they did in the past or alter their purchasing patterns, particularly because:

• we do not have any material long-term purchase arrangements with these or any of our other customers;

• substantially all of our sales to date have been 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; and

• some of our customers have sought or are seeking relationships with our current or potential competitors which may affect our customers’ purchasing decisions.

While we have been the sole supplier of the direct access arrangement, or DAA, ICs used in many of our customers’ soft modem DAA products and have also been a substantial supplier of synthesizers and transceivers to Samsung and other major GSM handset manufacturers, our customers regularly evaluate alternative sources of supply in the future in order to diversify their supplier base, which would increase their negotiating leverage with us and protect their ability to secure these components. We believe that any expansion of our customers’ supplier bases could have an adverse effect on the prices we are able to charge and volume of product that we are able to supply to our customers, which would negatively affect our revenues and operating results.

WE ARE SUBJECT TO RISKS RELATING TO PRODUCT CONCENTRATION AND LACK OF REVENUE DIVERSIFICATION

We derive a substantial portion of our revenues from a limited number of products, and we expect these products to continue to account for a large percentage of our revenues in the near term. Continued market acceptance of these products, is therefore, critical to our future success. In addition, substantially all of our products that we have sold include technology related to one or more of our issued U.S. patents. If these patents are found to be invalid or unenforceable, our competitors could introduce competitive products that could reduce both the volume and price per unit of our products. Our business, operating results, financial condition and cash flows could therefore be adversely affected by:

• a decline in demand for any of our more significant products, including our Aero Transceiver, RF Synthesizer, DAA, ISOmodem or ProSLIC;

• failure of our products to achieve continued market acceptance;

• an improved version of our products being offered by a competitor;

• technological change that we are unable to address with our products; and

• a failure to release new products or enhanced versions of our existing products on a timely basis and/or the failure of these products to achieve market acceptance.

We are particularly dependent on sales of our wireless products, which constituted almost half of our total revenues in 2002 and more than half of our total revenues during the first six months of fiscal 2003. If the market for GSM mobile handsets in which these products are incorporated deteriorates, our operating results would be materially and adversely affected.

IF WE ARE UNABLE TO DEVELOP NEW AND ENHANCED PRODUCTS THAT ACHIEVE MARKET ACCEPTANCE IN A TIMELY MANNER, OUR OPERATING RESULTS AND COMPETITIVE POSITION COULD BE HARMED

Our future success will depend on our ability to reduce our dependence on a few products by developing new ICs and product enhancements that achieve market acceptance in a timely and cost-effective manner. The development of mixed-signal ICs is highly complex, and we occasionally have experienced delays in completing the development and introduction of new products and product enhancements. Successful product development and market acceptance of our products depend on a number of factors, including:

• changing requirements of customers within the communications markets;

• accurate prediction of market requirements;

• timely completion and introduction of new designs;

• timely qualification and certification of our ICs for use in our customers’ products;

• commercial acceptance and volume production of the products into which our ICs will be incorporated;

• availability of foundry, assembly and test capacity;

• achievement of high manufacturing yields;

• quality, price, performance, power use and size of our products;

• availability, quality, price and performance of competing products and technologies;

• our customer service and support capabilities and responsiveness;

• successful development of our relationships with existing and potential customers;

• changes in technology, industry standards or end-user preferences; and

• cooperation of software partners and semiconductor partners to support our chips within a system.

We cannot provide any assurance that products which we recently have developed or may develop in the future will achieve market acceptance. We have introduced to market or are in development of many ICs. If our ICs fail to achieve market acceptance, or if we fail to develop new products that achieve market acceptance, our growth prospects, operating results and competitive position could be adversely affected.

OUR RESEARCH AND DEVELOPMENT EFFORTS ARE FOCUSED ON A LIMITED NUMBER OF NEW TECHNOLOGIES AND PRODUCTS, AND ANY DELAY IN THE DEVELOPMENT, OR ABANDONMENT, OF THESE TECHNOLOGIES OR PRODUCTS BY INDUSTRY PARTICIPANTS, OR THEIR FAILURE TO ACHIEVE MARKET ACCEPTANCE, COULD COMPROMISE OUR COMPETITIVE POSITION

Our ICs are used as components in communications devices in various markets. As a result, we have devoted and expect to continue to devote a large amount of resources to develop products based on new and emerging technologies and standards that will be commercially introduced in the future. Research and development expense for the six months ended June 28, 2003 was $21.2 million, or 15.9% of revenues. A number of large companies in the communications industry are actively involved in the development of these new technologies and standards. Should any of these companies delay or abandon their efforts to develop

commercially available products based on new technologies and standards, our research and development efforts with respect to these technologies and standards likely would have no appreciable value. In addition, if we do not correctly anticipate new technologies and standards, or if the products that we develop based on these new technologies and standards fail to achieve market acceptance, our competitors may be better able to address market demand than we would. Furthermore, if markets for these new technologies and standards develop later than we anticipate, or do not develop at all, demand for our products that are currently in development would suffer, resulting in lower sales of these products than we currently anticipate. For example, we have introduced to market the Aero Transceiver product for use in wireless phones operating on the GSM standard. The Aero Transceiver is also compatible with the GPRS standard, which we believe is the emerging data communications protocol for GSM based wireless phones. We cannot be certain that these standards will not change, thereby making our products unsuitable or impractical. Additionally, despite the published GSM/GPRS specifications, mobile phone network operators may demand increased performance beyond specifications for this highly competitive market. In the area of optical networking, our clock and data recovery integrated circuit operates within stringent specifications for high speed communications systems known as SONET. Changes to this standard could make our products uncompetitive or unsuitable to changing system requirements and result in our inability to sell these products.

OUR INABILITY TO MANAGE GROWTH COULD MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS

In recent periods, we have significantly increased the scope of our operations and expanded our workforce from 279 employees at the end of fiscal 2001 to 412 employees at June 28, 2003. This growth has placed, and any future growth of our operations will continue to place, a significant strain on our management personnel, systems and resources. We anticipate that we will need to implement a variety of new and upgraded operational and financial systems, procedures and controls, including the improvement of our accounting and other internal management systems. We are currently in the process of implementing supply chain management software. If such software does not function as expected, our sales and operating results could be materially and adversely affected. We also expect that we will need to continue to expand, train, manage and motivate our workforce. All of these endeavors will require substantial management effort, and we anticipate that we will require additional management personnel and internal processes to manage these efforts and to plan for the succession from time to time of certain persons who have been key management and technical personnel. If we are unable to effectively manage our expanding operations, our business could be materially and adversely affected.

WE RELY ON THIRD PARTIES TO MANUFACTURE, ASSEMBLE AND TEST OUR PRODUCTS AND THE FAILURE TO SUCCESSFULLY MANAGE OUR RELATIONSHIPS WITH OUR MANUFACTURERS AND SUBCONTRACTORS WOULD NEGATIVELY IMPACT OUR ABILITY TO SELL OUR PRODUCTS

We do not have our own wafer fab manufacturing facilities. Therefore, we rely principally on one third-party vendor, Taiwan Semiconductor Manufacturing Co. (TSMC), to manufacture the ICs we design. We also currently rely principally on two third-party assembly subcontractors, Advanced Semiconductor Engineering and Amkor, to assemble and package the silicon chips provided by the wafers for use in final products. Additionally, we rely on third-party vendors for a portion of the testing requirements of our products prior to shipping. We also maintain testing facilities in Austin, Texas. However, we have increasingly utilized offshore third-party test subcontractors, typically in Asia, where the parts are assembled and where the products are more frequently delivered to our customers. We expect this trend toward utilization of offshore third-party test subcontractors to continue.

There are significant risks associated with relying on these third-party foundries and subcontractors, including:

• failure by us, our customers or their end customers to qualify a selected supplier;

• capacity shortages during periods of high demand;

• potential insolvency of the third-party subcontractors;

• reduced control over delivery schedules and quality;

• limited warranties on wafers or products supplied to us;

• potential increases in prices;

• increased need for international-based supply and logistics management;

• their inability to supply or support new or changing packaging technologies; and

• low test yields.

We typically do not have long-term supply contracts with our third-party vendors, and, 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 purchase order. Although we believe that other semiconductor foundries or assembly or test subcontractors can adequately address our needs, we expect that it would take approximately six to twelve months to transition performance of these services from our current providers to new providers. Such a transition may also require a qualification process by our customers or their end customers. We generally place orders for products with some of our suppliers approximately three to four months prior to the anticipated delivery date, with order volumes based on our forecasts of demand from our customers. Accordingly, if we do not accurately forecast demand for our products, we may be unable to obtain adequate foundry or assembly capacity from our third-party foundry and assembly subcontractors to meet our customers’ delivery requirements, or we may accumulate excess inventories. On occasion, we have been unable to adequately respond to unexpected increases in customer purchase orders, and, therefore, were unable to benefit from this incremental demand. Beyond our current forecast, our third-party foundry or assembly or test subcontractors typically do not provide guarantees to us that adequate capacity will be available to us within the time required to meet additional demand for our products.

Since our inception, substantially all of the silicon wafers for the products that we have shipped were manufactured either by TSMC or its affiliates. Our customers typically complete their own qualification process. If we fail to properly balance customer demand across the existing semiconductor fabrication facilities that we utilize or are required by our foundry partners to increase, or otherwise change the number of fab lines that we utilize for our production, we might not be able to fulfill demand for our products and may need to divert our engineering resources away from new product development initiatives to support the fab line transition, which would adversely affect our operating results. Additionally, a resulting write off of unusable or excess inventories would contribute to a decline in earnings.

WE HAVE INCREASED OUR INTERNATIONAL ACTIVITIES SIGNIFICANTLY AND PLAN TO CONTINUE SUCH EFFORTS, WHICH SUBJECTS US TO ADDITIONAL BUSINESS RISKS INCLUDING INCREASED LOGISTICAL COMPLEXITY, POLITICAL INSTABILITY AND CURRENCY FLUCTUATIONS

We recently established additional international subsidiaries and have opened additional offices in international markets to expand our international activities in Europe and the Pacific Rim region. The percentage of our revenues to customers located outside of the United States was 79% in fiscal 2002, 66% in fiscal 2001 and 21% in fiscal 2000. We may not be able to maintain or increase international market demand for our products. Our international operations are subject to a number of risks, including:

• increased complexity and costs of managing international operations;

• protectionist laws and business practices that favor local competition in some countries;

• multiple, conflicting and changing laws, regulations and tax schemes;

• longer sales cycles;

• greater difficulty in accounts receivable collection and longer collection periods;

• high levels of distributor inventory subject to rights of return to us;

• political and economic instability; and

• greater difficulty in hiring qualified technical sales and applications engineers.

To date, all of our sales to international customers and purchases of components from international suppliers have been denominated in U.S. dollars. As a result, an increase in the value of the U.S. dollar relative to foreign currencies could make our products more expensive for our international customers to purchase, thus rendering our products less competitive.

OUR CURRENT MANUFACTURERS, ASSEMBLERS, TEST SERVICE PROVIDERS, AND CUSTOMERS ARE CONCENTRATED IN THE SAME GEOGRAPHIC REGION, WHICH INCREASES THE RISK THAT A NATURAL DISASTER, EPIDEMIC, LABOR STRIKE, WAR OR POLITICAL UNREST COULD DISRUPT OUR OPERATIONS OR SALES

Our current semiconductor wafer manufacturer’s foundries are located in the same region within Taiwan and our assembly and test subcontractors are located in the Pacific Rim region. In addition, many of our customers, particularly mobile telephone manufacturers, are located in the Pacific Rim region. The risk of earthquakes in Taiwan and the Pacific Rim region is significant due to the proximity of major earthquake fault lines in the area. We are not currently covered by insurance against business disruption caused by earthquakes as such insurance is not currently available on terms that we believe are commercially reasonable. Earthquakes, fire, flooding or other natural disasters in Taiwan or the Pacific Rim region, or an epidemic, political unrest, war, labor strikes or work stoppages in countries where our semiconductor manufacturer, assemblers and test subcontractors are located, likely would result in the disruption of our foundry, assembly or test capacity. There can be no assurance that such alternate capacity could be obtained on favorable terms, if at all.

A natural disaster, epidemic, labor strike, war or political unrest where our customers’ facilities are located would likely reduce our sales to such customers. For example, Samsung, our largest customer, is based in South Korea and represented 21.7% of our revenues during the first six months of 2003. North Korea’s recent decision to withdraw from the nuclear Non-Proliferation Treaty and related geopolitical maneuverings has created unrest. Such unrest could create economic uncertainty or instability, could escalate to war or otherwise adversely affect South Korea and our South Korean customers and reduce our sales to such customers, which would materially and adversely affect our operating results. In addition, a significant portion of the assembly and test of our wireless products occurs in South Korea. Any disruption resulting from these events could also cause significant delays in shipments of our products until we are able to shift our manufacturing, assembling or testing from the affected subcontractor to another third-party vendor.

THE SEMICONDUCTOR MANUFACTURING PROCESS IS HIGHLY COMPLEX AND, FROM TIME TO TIME, MANUFACTURING YIELDS MAY FALL BELOW OUR EXPECTATIONS, WHICH COULD RESULT IN OUR INABILITY TO SATISFY DEMAND FOR OUR PRODUCTS IN A TIMELY MANNER

The manufacture of silicon wafers for our products is a highly complex and technologically demanding process. Although we work closely with our foundries to minimize the likelihood of reduced manufacturing yields, our foundries from time to time have experienced lower than anticipated 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 deficiencies. If our foundries fail to deliver fabricated silicon wafers of satisfactory quality in a timely manner, we will be unable to meet our customers’ demand for our products in a timely manner, which would adversely affect our operating results and damage our customer relationships.

OUR PRODUCTS ARE COMPLEX AND MAY REQUIRE MODIFICATIONS TO RESOLVE UNDETECTED ERRORS WHICH COULD LEAD TO AN INCREASE IN OUR COSTS OR A REDUCTION IN OUR REVENUES

Our products are complex and may contain errors when first introduced or as new versions are released. We rely primarily on our in-house testing personnel to design test operations and procedures to detect any errors prior to delivery of our products to our customers. Because our products are manufactured by third parties, should problems occur in the operation or performance of our

ICs, we may experience delays in meeting key introduction dates or scheduled delivery dates to our customers. These errors also could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations and business reputation problems.

WE DEPEND ON OUR KEY PERSONNEL TO MANAGE OUR BUSINESS EFFECTIVELY IN A RAPIDLY CHANGING MARKET, 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, sales and marketing personnel. Our success to date has been highly dependent on Navdeep Sooch, our co-founder, Chief Executive Officer and Chairman of the Board, Daniel Artusi, our President and Chief Operating Officer, Jeffrey Scott, our co-founder and Vice President, and David Welland, our co-founder and Vice President. We believe that our future success will be dependent on retaining the services of these key personnel, developing their successors and certain internal processes to reduce our reliance on specific individuals, and on properly managing the transition of key roles when they occur. For example, our co-founder and CEO, Navdeep Sooch, has recently announced his desire to transition out of his role as CEO at the end of this year, while continuing to remain actively involved with us as Chairman of the Board. Daniel Artusi is anticipated to assume the additional role as CEO at that time. There is currently a shortage of qualified personnel with significant experience in the design, development, manufacturing, marketing and sales of analog and mixed-signal communications ICs. In particular, there is a shortage of engineers who are familiar with the intricacies of the design and manufacturability of analog elements, and competition for such personnel is intense. Our key technical personnel represent a significant asset and serve as the primary source for our technological and product innovations. We may not be successful in attracting and retaining sufficient numbers of technical personnel to support our anticipated growth. The loss of any of our key employees or the inability to attract or retain qualified personnel both in the United States and internationally, including engineers and sales and marketing personnel, could delay the development and introduction of, and negatively impact our ability to sell, our products.

WE MAY BE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY, WHICH WOULD NEGATIVELY AFFECT OUR ABILITY TO COMPETE

Our products rely on our proprietary technology, and we expect that future technological advances made by us will be critical to sustain market acceptance of our products. Therefore, we believe that the protection of our intellectual property rights is and will continue to be important to the success of our business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We also enter into confidentiality or license agreements with our employees, consultants, intellectual property providers and business partners, and control access to and distribution of our documentation and other proprietary information. Despite these efforts, unauthorized parties may attempt to copy or otherwise obtain and use our proprietary technology. Monitoring unauthorized use of our technology is difficult, and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. We cannot be certain that patents will be issued as a result of our pending applications nor can we be certain that any issued patents would protect or benefit us or give us adequate protection from competing products. For example, issued patents may be circumvented or challenged and declared invalid or unenforceable. We also cannot be certain that others will not develop effective competing technologies on their own.

SIGNIFICANT LITIGATION OVER INTELLECTUAL PROPERTY IN OUR INDUSTRY MAY CAUSE US TO BECOME INVOLVED IN COSTLY AND LENGTHY LITIGATION WHICH COULD SERIOUSLY HARM OUR BUSINESS

In recent years, there has been significant litigation in the United States involving patents and other intellectual property rights. From time to time, we receive letters from various industry participants alleging infringement of patents, trademarks or misappropriation of trade secrets or from customers requesting indemnification for claims brought against them by third parties. The exploratory nature of these inquiries has become relatively common in the semiconductor industry. We typically respond when

appropriate and as advised by legal counsel.

We have been involved in litigation to protect our intellectual property rights in the past and may become involved in such litigation again in the future. In April 2003, we paid $17 million to settle patent infringement claims brought against us by TDK Semiconductor Corporation. In the future, we may become involved in additional litigation to defend allegations of infringement asserted by others, both directly and indirectly as a result of certain industry-standard indemnities we may offer to our customers. Legal proceedings could subject us to significant liability for damages or invalidate our proprietary rights. Legal proceedings initiated by us to protect our intellectual property rights could also result in counterclaims or countersuits against us. Any litigation, regardless of its outcome, would likely be time-consuming and expensive to resolve and would divert our management’s time and attention. Any intellectual property litigation also could force us to take specific actions, including:

• cease selling products that use the challenged intellectual property;

• obtain from the owner of the infringed intellectual property a right to a license to sell or use the relevant technology, which license may not be available on reasonable terms, or at all;

• redesign those products that use infringing intellectual property; or

• pursue legal remedies with third parties to enforce our indemnification rights, which may not adequately protect our interests.

FAILURE TO MANAGE OUR DISTRIBUTION CHANNEL RELATIONSHIPS COULD IMPEDE OUR FUTURE GROWTH

The future growth of our business will depend in part on our ability to manage our relationships with current and future distributors and sales representatives, develop additional channels for the distribution and sale of our products and manage these relationships. As we execute our indirect sales strategy, we will need to manage the potential conflicts that may arise with our direct sales efforts. For example, conflicts with a distributor may arise when a customer begins purchasing directly from us rather than through the distributor. The inability to successfully execute or manage a multi-channel sales strategy could impede our future growth.

WE COULD SEEK TO RAISE ADDITIONAL CAPITAL IN THE FUTURE THROUGH THE ISSUANCE OF EQUITY OR DEBT SECURITIES, BUT ADDITIONAL CAPITAL MAY NOT BE AVAILABLE ON TERMS ACCEPTABLE TO US, OR AT ALL

We believe that our existing cash, cash equivalents, investments and bank credit facility will be sufficient to meet our working capital needs, capital expenditures, investment requirements and commitments for at least the next 12 months. However, it is possible that we may need to raise additional funds to finance our activities or to facilitate acquisitions of other businesses, products or technologies. We believe we could raise these funds, if needed, by selling equity or debt securities to the public or to selected investors. In addition, even though we may not need additional funds, we may still elect to sell additional equity or debt securities or obtain credit facilities for other reasons. However, we may not be able to obtain additional funds on favorable terms, or at all. If we decide to raise additional funds by issuing equity or convertible debt securities, the ownership percentages of existing shareholders would be reduced.

ANY ACQUISITIONS WE MAKE COULD DISRUPT OUR BUSINESS AND HARM OUR FINANCIAL CONDITION

As part of our growth and product diversification strategy, we will continue to evaluate opportunities to acquire other businesses or technologies that would complement our current offerings, expand the breadth of our markets or enhance our technical capabilities. Acquisitions that we may potentially make in the future entail a number of risks that could materially and adversely affect our business and operating results, including:

• problems integrating the acquired operations, technologies or products with our existing business and products;

• diversion of management’s time and attention from our core business;

• need for financial resources above our planned investment levels;

• difficulties in retaining business relationships with suppliers and customers of the acquired company;

• risks associated with entering markets in which we lack prior experience;

• potential loss of key employees of the acquired company; and

• potential requirement to amortize intangible assets.

Future acquisitions also could cause us to incur debt or contingent liabilities or cause us to issue equity securities that could negatively impact the ownership percentages of existing shareholders.

A SUBSTANTIAL PORTION OF THE FINAL TESTING OF OUR PRODUCTS IS PERFORMED INTERNALLY BY US, WHICH INCREASES OUR FIXED COSTS

Although we are increasingly relying on third parties to test our products, we have invested substantial resources to acquire state-of-the-art testing equipment and hire additional qualified personnel, which has increased our fixed costs. If demand for our products does not support the effective utilization of these employees and additional equipment or if we elect to rely on third parties for testing services, we may not realize the anticipated benefits from our investments in internal test capacity. If our internal test operations are underused or mismanaged, we may incur significant costs that could adversely affect our operating results. In addition, test equipment that we have purchased may become obsolete as a result of our introduction of new products which require new testing equipment. Such obsolescence could result in substantial impairment charges to reflect the write-off of such equipment which would adversely affect our operating results.

OUR CUSTOMERS REQUIRE OUR PRODUCTS TO UNDERGO A LENGTHY AND EXPENSIVE QUALIFICATION PROCESS WITHOUT ANY ASSURANCE OF PRODUCT SALES

Prior to purchasing our products, our customers require that our products undergo an extensive qualification process, which involves testing of the products in the customer’s system as well as rigorous reliability testing. This qualification process may continue for six months or longer. However, qualification of a product by a customer does not ensure any sales of the product to that customer. Even after successful qualification and sales of a product to a customer, a subsequent revision to the IC, changes in its manufacturing process or the selection of a new supplier by us may require a new qualification process, which may result in delays and in us holding excess or obsolete inventory. After our products are qualified, it can take an additional six months or more before the customer commences volume production of components or devices that incorporate our products. Despite these uncertainties, we devote substantial resources, including design, engineering, sales, marketing and management efforts, toward qualifying our products with customers in anticipation of sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, such failure or delay would preclude or delay sales of such product to the customer, which may impede our growth and cause our business to suffer.

WE DEPEND ON OUR CUSTOMERS TO SUPPORT OUR PRODUCTS

Our products are currently used by our customers to produce modems, telephony equipment, mobile telephones, various wireless devices and optical networking equipment. We rely on our customers to provide hardware, software, intellectual property indemnification and other technical support for the products supplied by our customers. If our customers do not provide the required functionality or if our customers do not provide satisfactory support for their products, the demand for these devices that incorporate our products may diminish or we may otherwise be materially adversely affected. Any reduction in the demand for these devices would significantly reduce our revenues.

WE ARE SUBJECT TO INCREASED INVENTORY RISKS AND COSTS BECAUSE WE BUILD OUR PRODUCTS BASED ON FORECASTS PROVIDED BY CUSTOMERS BEFORE RECEIVING PURCHASE ORDERS FOR THE PRODUCTS

In order to ensure availability of our products for some of our largest customers, we start the manufacturing of our products in advance of receiving purchase orders based on forecasts provided by these customers. However, these forecasts do not represent

binding purchase commitments and we do not recognize sales for these products until they are shipped to the customer. As a result, we incur inventory and manufacturing costs in advance of anticipated sales. Because demand for our products may not materialize, manufacturing based on forecasts subjects us to increased risks of high inventory carrying costs and increased obsolescence and may increase our operating costs. These inventory risks are exacerbated when our customers purchase indirectly through contract manufacturers because this causes us to have less visibility regarding the accumulated levels of inventory for such customers.

WE ARE SUBJECT TO CREDIT RISKS RELATED TO OUR ACCOUNTS RECEIVABLE, ESPECIALLY WHEN CUSTOMERS PURCHASE PRODUCTS THROUGH DISTRIBUTORS AND CONTRACT MANUFACTURERS

We do not generally obtain letters of credit or other security for payment from customers, distributors or contract manufacturers. Accordingly, we are not protected against accounts receivable default or bankruptcy by these entities. If we are unable to collect our accounts receivable, our operating results could be materially harmed. A significant portion of our revenues are realized through indirect channels such as distributors and contract manufacturers, with a significant portion being located outside the United States. At June 28, 2003, gross receivable balances from distributors and contract manufacturers totaled $13.0 million. Distributors and contract manufacturers may be dependent on receiving payment from the ultimate customers for the resources necessary to pay us. None of our shipments to distributors and contract manufacturers are guaranteed by the ultimate customer. If for any reason a customer does not pay the distributor or contract manufacturer, there are no assurances that our direct contractual customers will have adequate working capital to enable the collection of our accounts receivable. We continue to monitor the credit worthiness and payment practice of each of the distributors or contract manufacturers, and to date have not had any significant write-offs of receivable balances from them.

WE ARE A RELATIVELY SMALL COMPANY WITH LIMITED RESOURCES COMPARED TO SOME OF OUR CURRENT AND POTENTIAL COMPETITORS AND WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY AND INCREASE MARKET SHARE

Some of our current and potential competitors have longer operating histories, significantly greater resources and name recognition and a larger base of customers than we have. As a result, these competitors may have greater credibility with our existing and potential customers. They also may be able to adopt more aggressive pricing policies and devote greater resources to the development, promotion and sale of their products than we can to ours. In addition, some of our current and potential competitors have already established supplier or joint development relationships with the decision makers at our current or potential customers. These competitors may be able to leverage their existing relationships to discourage their customers from purchasing products from us or persuade them to replace our products with their products. Our competitors may also offer bundled chipset kit arrangements offering a more complete product despite the technical merits or advantages of our products. These competitors may elect not to support our products which could complicate our sales efforts. These and other competitive pressures may prevent us from competing successfully against current or future competitors, and may materially harm our business. Competition could decrease our prices, reduce our sales, lower our gross profits or decrease our market share.

OUR STOCK PRICE MAY BE VOLATILE

The market price of our common stock has been volatile in the past and may be volatile in the future. The market price of our common stock may be significantly affected by the following factors:

• actual or anticipated fluctuations in our operating results;

• changes in financial estimates by securities analysts or our failure to perform in line with such estimates;

• changes in market valuations of other technology companies, particularly semiconductor companies;

• announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures or capital commitments;

• introduction of technologies or product enhancements that reduce the need for our products;

• the loss of one or more key original equipment manufacturers (OEM) customers; and

• departures of key personnel.

The stock market has experienced extreme volatility that often has been unrelated to the performance of particular companies. These market fluctuations may cause our stock price to fall regardless of our performance.

PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW COULD PREVENT, DELAY OR IMPEDE A CHANGE IN CONTROL OF US AND MAY REDUCE THE MARKET PRICE OF OUR COMMON STOCK

Provisions of our certificate of incorporation and bylaws could have the effect of discouraging, delaying or preventing a merger or acquisition that a stockholder may consider favorable. For example, our certificate of incorporation and bylaws provide for:

• the division of our board of directors into three classes to be elected on a staggered basis, one class each year;

• the ability of our board of directors to issue shares of our preferred stock in one or more series without further authorization of our stockholders;

• a prohibition on stockholder action by written consent;

• elimination of the right of stockholders to call a special meeting of stockholders;

• a requirement that stockholders provide advance notice of any stockholder nominations of directors or any proposal of new business to be considered at any meeting of stockholders; and

• a requirement that a supermajority vote be obtained to amend or repeal certain provisions of our certificate of incorporation.

We also are subject to the anti-takeover laws of Delaware which may discourage, delay or prevent someone from acquiring or merging with us, which may adversely affect the market price of our common stock.

THE PERFORMANCE OF OUR NEXT GENERATION DIRECT ACCESS ARRANGEMENT PRODUCTS MAY BE ADVERSELY AFFECTED BY SEVERE ENVIRONMENTAL CONDITIONS THAT MAY REQUIRE MODIFICATIONS, WHICH COULD LEAD TO AN INCREASE IN OUR COSTS OR A REDUCTION IN OUR REVENUES

Although our DAA products are compliant with published specifications, these established specifications might not adequately address all conditions that must be satisfied in order to operate in harsh environments. This includes environments where there are wide variations in electrical quality, telephone line quality, static electricity and operating temperatures or that may be affected by lightning or improper handling by customers and end users. Our next generation products have had a limited period of time in the field under operation, and these environmental factors may result in unanticipated returns of our products. Any necessary modifications could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations and business reputation problems.

RISKS RELATED TO OUR INDUSTRY

COMPETITION WITHIN THE NUMEROUS MARKETS WE TARGET MAY REDUCE SALES OF OUR PRODUCTS AND REDUCE MARKET SHARE

The markets for semiconductors in general, and for mixed-signal ICs in particular, are intensely competitive. We expect that the market for our products will continually evolve and will be subject to rapid technological change. In addition, as we target and supply products to numerous markets and applications, we face competition from a relatively large number of competitors. Across all of our

product areas, we compete with Agere Systems, AMCC, Analog Devices, Broadcom, Conexant, Cypress, ESS, Fujitsu, Hitachi, Infineon Technologies, Legerity, Maxim Integrated Products, National Semiconductor, Philips, RF Micro Devices, Semtech, Skyworks Solutions Inc., Texas Instruments, Vitesse Semiconductor, and others. We expect to face competition in the future from our current competitors, other manufacturers and designers of semiconductors, and innovative start-up semiconductor design companies. Some of our customers, such as Agere Systems, Broadcom, Intel, Motorola, Samsung and Texas Instruments, are also large, established semiconductor suppliers. Our sales to and support of these customers may enable them to become a source of competition to us, despite our efforts to protect our intellectual property rights. As the markets for communications products grow, we also may face competition from traditional communications device companies. These companies may enter the mixed-signal semiconductor market by introducing their own ICs or by entering into strategic relationships with or acquiring other existing providers of semiconductor products.

In addition, our largest competitors may restructure their operations to create separate companies that are more focused on providing the types of products we produce or acquire our customers. For example, Conexant is a significant competitor of ours across multiple product areas. In June 2002, Conexant completed the spin-out of Skyworks Solutions, resulting from the combination of Conexant’s wireless business with Alpha Industries. In May 2003, Conexant acquired PC-Tel’s modem business. In the future, Conexant may seek to supplant our silicon DAA products that have historically been incorporated in PC-Tel’s products with Conexant’s own competing DAA product.

THE AVERAGE SELLING PRICES OF OUR PRODUCTS COULD DECREASE RAPIDLY WHICH MAY NEGATIVELY IMPACT OUR REVENUES AND GROSS PROFITS

We may experience substantial period-to-period fluctuations in future operating results due to the erosion of our average selling prices. We have reduced the average unit price of our products in anticipation of future competitive pricing pressures, new product introductions by us or our competitors and other factors. The highly competitive GSM handset market is extremely cost sensitive due to the potentially very high volumes and stringent expectations placed on consumer electronics component suppliers for aggressive and sustained price reductions which do result in declining average selling prices. We expect that these factors will create downward pressure on our average selling prices and gross profit percentages. If we are unable to offset any such reductions in our average selling prices by increasing our sales volumes and corresponding production cost reductions, our gross profits and revenues will suffer. To maintain our gross profit percentage, we will need to develop and introduce new products and product enhancements on a timely basis and continually reduce our costs. Our failure to do so would cause our revenues and gross profit percentage to decline.

WE ARE SUBJECT TO THE CYCLICAL NATURE OF THE SEMICONDUCTOR INDUSTRY, WHICH HAS BEEN SUBJECT TO SIGNIFICANT DOWNTURNS

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 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. Specific areas of the communications markets have contributed to the overall decline and volatility of the semiconductor industry in the recent past. For example, in fiscal 2001, the semiconductor industry suffered a downturn due to reductions in the actual unit sales of personal computers and wireless phones as compared to previous robust forecasts. Additionally, changing and competing technical standards in airwave interfaces such as GSM and Code Division Multiple Access (CDMA) for mobile handsets, migration to higher speed communication protocols in the optical space and the return to prominence of the traditional regional Bell operating companies compared to the competitive local exchange companies all have contributed to the volatility in the communications area of the semiconductor industry. This downturn resulted in a material adverse effect on our business and operating results in fiscal 2001.

Due to the cyclical nature of the semiconductor industry, an upturn in business could result in increased competition for access to third-party foundry, assembly and test capacity. We are dependent on the availability of such capacity to manufacture, assemble and test our ICs. None of our third-party foundry, assembly or test subcontractors have provided assurances that adequate capacity will be available to us.

OUR PRODUCTS MUST CONFORM TO INDUSTRY STANDARDS IN ORDER TO BE ACCEPTED BY END USERS IN OUR MARKETS

Generally, our products comprise only a part of a communications device. All components of such devices must uniformly comply with industry standards in order to operate efficiently together. We depend on companies that provide other components of the devices to support prevailing industry standards. Many of these companies are significantly larger and more influential in affecting industry standards than we are. Some industry standards may not be widely adopted or implemented uniformly, and competing standards may emerge that may be preferred by our customers or end users. If larger companies do not support the same industry standards that we do, or if competing standards emerge, market acceptance of our products could be adversely affected which would harm our business.

Products for communications applications are based on industry standards that are continually evolving. Our ability to compete in the future will depend on our ability to identify and ensure compliance with these evolving industry standards. The emergence of new industry standards could render our products incompatible with products developed by other suppliers. As a result, we could be required to invest significant time and effort and to incur significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards for a significant period of time, we could miss opportunities to achieve crucial design wins. We may not be successful in developing or using new technologies or in developing new products or product enhancements that achieve market acceptance. Our pursuit of necessary technological advances may require substantial time and expense.

We performed an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rule 13a-14(c) under the Securities Exchange Act of 1934 (the “Exchange Act”). Based on that evaluation, our management, including our CEO and CFO, concluded that our disclosure controls and procedures were effective as of June 28, 2003 to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. There have been no significant changes in our internal controls or other factors that could significantly affect our internal controls subsequent to June 28, 2003.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Patent Infringement Litigation Settlement

On April 1, 2003, we settled the patent infringement lawsuit brought against us by TDK Semiconductor Corporation (TDK) for alleged infringement of TDK’s United States Patent No. 5,654,984. Under the terms of the settlement agreement, TDK agreed to release all claims covered by the lawsuit. In addition, TDK granted us irrevocable, royalty-free licenses for the patent covered by the lawsuit and certain other related patents. In exchange, we made a one-time payment of $17 million to TDK and released all counterclaims covered by the lawsuit. Prior to the settlement, the case was pending in the United States District Court for the Central District of California. On April 4, 2003, the Court entered a stipulated order of dismissal with prejudice of all claims and counterclaims asserted in the lawsuit.

Securities Litigation

On December 6, 2001, a class action complaint for violations of U.S. federal securities laws was filed in the United States District Court for the Southern District of New York against us, four officers individually and the three investment banking firms who served as representatives of the underwriters in connection with our initial public offering of common stock which became effective on March 23, 2000. On April 19, 2002, a Consolidated Amended Complaint, which is now the operative complaint, was filed in the same court. The complaint alleges that the registration statement and prospectus for our initial public offering did not disclose that (1) the underwriters solicited and received additional, excessive and undisclosed commissions from certain investors, and (2) the underwriters had agreed to allocate shares of the offering in exchange for a commitment from the customers to purchase additional shares in the aftermarket at pre-determined higher prices. The action seeks damages in an unspecified amount and is being coordinated with approximately 300 other nearly identical actions filed against other companies. On July 15, 2002, we moved to dismiss all claims against us and the individual defendants. A court order dated October 9, 2002 dismissed without prejudice numerous individual defendants, including the four officers of our company who had been named individually. On February 19, 2003, the Court denied the motion to dismiss the complaint against us. The plaintiff class has proposed a Memorandum of Understanding (“MOU”) and related agreements which set forth the terms of a proposed settlement between the plaintiff class and the Company and the other approximately 300 defendants. It is anticipated that any potential financial obligation of the Company to plaintiffs due pursuant to the terms of the MOU and related agreements would be covered by existing insurance. Therefore, we do not expect that the proposed settlement would involve any payment by the Company. The MOU and related agreements are subject to a number of contingencies, including the approval of the MOU by a sufficient number of the other approximately 300 defendants, the negotiation of a final settlement agreement, and approval of the settlement by the court. We cannot be certain as to whether or when a settlement will occur or be finalized and are unable at this time to determine whether the outcome of the litigation will have a material impact on our results of operations or financial condition in any future period.

We are not currently involved in any other material legal proceedings.

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

Our registration statement (Registration No. 333-94853) under the Securities Act of 1933, as amended, relating to our initial public offering of our common stock became effective on March 23, 2000. A total of 3,680,000 shares of common stock were registered. We sold a total of 3,200,000 shares of our common stock and selling stockholders sold a total of 480,000 shares to an underwriting syndicate. The managing underwriters were Morgan Stanley & Co. Incorporated, Lehman Brothers Inc., and Salomon Smith Barney Inc. The offering commenced and was completed on March 24, 2000, at a price to the public of $31.00 per share. The initial public offering resulted in net proceeds to us of $90.6 million, after deducting underwriting commissions of $6.9 million and offering expenses of $1.6 million. We used $15 million of the proceeds as part of the consideration paid in the acquisition of Krypton Isolation, Inc. on August 9, 2000. Another $4.3 million was used to pay off equipment loans provided by Imperial Bank. We used

another $1.0 million of the proceeds as part of the consideration paid in the acquisition of SNR Semiconductor Incorporated (SNR) on October 2, 2000. In December 2002, we prepaid $2.4 million in satisfaction of our remaining debt and lease obligations to three equipment financing institutions. As of June 28, 2003, the remaining proceeds were invested in short-term, investment-grade, interest bearing instruments.
