PROSPECTUS SUMMARY YOU SHOULD READ THE FOLLOWING SUMMARY TOGETHER WITH THE MORE DETAILED INFORMATION REGARDING OUR COMPANY AND THE COMMON STOCK BEING SOLD IN THIS OFFERING, ESPECIALLY THE RISKS OF INVESTING IN OUR COMMON STOCK DISCUSSED UNDER THE CAPTION "RISK FACTORS" AND OUR FINANCIAL STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE IN THIS PROSPECTUS. SILICON LABORATORIES We are a leader in the design and development of proprietary, analog-intensive, mixed-signal integrated circuits, or ICs, for the rapidly growing communications industry. Mixed-signal ICs are electronic components that convert real-world analog signals, such as sound and radio waves, into digital signals that electronic products can process. Mixed-signal ICs are critical components of numerous communications products, including cellular telephones, cable and satellite set-top boxes, modems and fax machines. Our ICs can dramatically reduce the cost, size and system power requirements of these communications products. To develop our business rapidly, we initially focused our efforts on developing ICs for the personal computer modem market. We are now applying our mixed-signal and communications expertise to the development of innovative ICs for other communications markets with high growth potential, such as cellular telephones and network access applications. Our five largest customers in 1999 were Intel, Motorola, PC-Tel, SmartLink and 3Com. We have no long-term purchase commitments from any of our customers. Within the semiconductor industry, we are known as a "fabless" company, meaning that we do not fabricate the semiconductors that we design and develop, but instead rely on third parties to manufacture our products. We design our ICs to be manufactured using standard complementary metal oxide semiconductor, or CMOS, technology, which involves less cost and complexity in the manufacturing process than competing technologies. As a result, our ICs can be reliably manufactured at a reduced cost and in high volume at semiconductor foundries around the world. Demand for communications services has increased at a rapid rate in recent years due to a number of factors, including the growth of Internet usage, development of new communications technologies, availability of improved communications services at lower costs and remote access requirements for corporate networks. This demand has fueled tremendous growth in the number of wireline and wireless communications devices used to access these services. Digital communications devices typically require mixed-signal circuits to access the communications networks to which they are connected. In order to improve their competitive position, communications device manufacturers need advanced mixed-signal ICs to create smaller products with improved price/ performance characteristics. Manufacturers of communications devices must rapidly introduce new and advanced products and must adapt to evolving industry standards and new technologies to remain competitive. Because analog-intensive, mixed-signal IC design expertise is difficult to find, these manufacturers increasingly are turning to third parties, such as Silicon Laboratories with its world-class design talent, to provide advanced mixed-signal ICs. This expertise is even more important when designing within the limitations of standard CMOS manufacturing processes rather than alternative semiconductor processes, which are typically more expensive and not as widely available. Our mixed-signal ICs provide our customers with the following benefits: - DRAMATICALLY IMPROVED SIZE AND PRICE/PERFORMANCE CHARACTERISTICS. By significantly reducing the number of discrete components used in communications devices, our ICs enable our customers to offer products with smaller sizes, lower costs, reduced power consumption and with increased performance and reliability. - REDUCED TIME REQUIRED TO BRING A PRODUCT TO MARKET. We design our mixed-signal ICs to be integrated with the products of multiple manufacturers and conduct extensive research and development to ensure that they conform to our customers' evolving technical standards. As a result, our customers are able to rapidly integrate our ICs into their designs and reduce the time it takes to begin marketing their products. - ATTRACTIVE NEW PRODUCT OPPORTUNITIES. Our space-saving and cost-efficient ICs allow our customers to create smaller and more cost-effective products for use in many evolving markets for communications devices. 3

WE PLAN TO INCREASE OUR INTERNATIONAL SALES ACTIVITIES SIGNIFICANTLY, WHICH WILL SUBJECT US TO ADDITIONAL BUSINESS RISKS INCLUDING INCREASED LOGISTICAL COMPLEXITY, POLITICAL INSTABILITY AND CURRENCY FLUCTUATIONS We intend to open sales offices in international markets to expand our international sales activities in Europe and the Pacific Rim region. Our planned international sales growth will be limited if we are unable to hire additional personnel and develop relationships with international distributors. 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; and - political and economic instability. 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 them less competitive. OUR INABILITY TO MANAGE GROWTH COULD MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS During the past year, we have significantly increased the scope of our operations and expanded our workforce from 42 employees at January 2, 1999 to 148 employees at January 1, 2000. 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 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. If we are unable to effectively manage our expanding operations, our business could be materially and adversely affected. 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 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 our unpatented proprietary technology or effective competing technologies on their own. 13
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 or trade secrets. 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 may become involved in litigation to protect our intellectual property rights or to defend allegations of infringement asserted by others. 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 potential 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 right a license to sell or use the relevant technology, which license may not be available on reasonable terms, or at all; or - redesign those products that use infringing intellectual property. On January 12, 2000, we filed a lawsuit against Analog Devices and 3Com claiming that Analog Devices has infringed, and is continuing to infringe, our issued U.S. patent with respect to our DAA technology and that Analog Devices and 3Com have misappropriated our confidential information, know-how and trade secrets. On January 25, 2000, Analog Devices filed an answer denying that it has misappropriated our confidential information, know-how and trade secrets and brought a counterclaim against us seeking a declaratory judgment that our issued U.S. patent is invalid and unenforceable and that Analog Devices has not infringed our issued U.S. patent. We filed an answer to Analog Devices' counterclaim asserting that our issued U.S. patent is valid and enforceable and that Analog Devices has infringed our issued U.S. patent. 3Com has not yet filed a response to our lawsuit. Our lawsuit will involve significant expense and divert our management's time and attention from other aspects of our business. The lawsuit may also damage our business relationship with 3Com which accounted for 10% of our sales in fiscal 1999 and 20% of our sales in fiscal 1998. Due to the inherent uncertainties of litigation, we cannot be certain of the outcome of this lawsuit. ANY ACQUISITIONS WE MAKE COULD DISRUPT OUR BUSINESS AND HARM OUR FINANCIAL CONDITION As part of our growth strategy, we may consider opportunities to acquire other businesses or technologies that would complement our current offerings, expand the breadth of our markets or enhance our technical capabilities. To date, we have not made any acquisitions and we are currently not subject to any agreement or letter of intent with respect to potential acquisitions. Acquisitions 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; - difficulties in retaining business relationships with suppliers and customers of the acquired company; - risks associated with entering markets in which we lack prior experience; and - potential loss of key employees of the acquired company. 14
FAILURE TO EXPAND OUR DISTRIBUTION CHANNELS AND MANAGE OUR DISTRIBUTION RELATIONSHIPS COULD IMPEDE OUR FUTURE GROWTH The future growth of our business will depend in part on our ability to expand our existing relationships with distributors and sales representatives, develop additional channels for the distribution and sale of our products and manage these relationships. As part of our channel sales strategy, we intend to expand our relationships with distributors and sales representatives. As we develop our indirect sales capabilities, we will need to manage the potential conflicts that may arise with our direct sales efforts. The inability to successfully execute or manage a multi-channel sales strategy could impede our future growth. 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, including wireline, wireless and other communications markets, we face competition from a relatively large number of competitors. Across all of our product areas, we compete with Advanced Micro Devices, Analog Devices, Conexant, Delta Integration, Fujitsu, Infineon Technologies, Krypton Isolation, National Semiconductor, Philips and Texas Instruments, among 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 Intel, Lucent and Motorola, 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 communication 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. THE AVERAGE SELLING PRICES OF OUR PRODUCTS COULD DECREASE RAPIDLY WHICH MAY NEGATIVELY IMPACT OUR GROSS MARGINS AND SALES 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. We expect that we will have to do so again in the future. If we are unable to offset any such reductions in our average selling prices by increasing our sales volumes, our gross profits and sales will suffer. To maintain gross margins, 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 sales and gross margins to decline. OUR CUSTOMERS REQUIRE OUR PRODUCTS TO UNDERGO A LENGTHY AND EXPENSIVE QUALIFICATION PROCESS WHICH DOES NOT ASSURE PRODUCT SALES Prior to purchasing our products, our customers require that our products undergo an extensive qualification process, which involves testing of the product 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 assure 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 products that incorporate our products. Despite these uncertainties, we devote substantial resources, 15
including identification, 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 ARE SUBJECT TO THE CYCLICAL NATURE OF THE SEMICONDUCTOR INDUSTRY 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. Any future downturns could have a material adverse effect on our business and operating results. Furthermore, any upturn in the semiconductor industry could result in increased competition for access to third-party foundry and assembly capacity. We are dependent on the availability of such capacity to manufacture and assemble our ICs. None of our third-party foundry or assembly contractors 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 effecting 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. RISKS RELATED TO THIS OFFERING OUR MANAGEMENT MAY APPLY THE PROCEEDS OF THIS OFFERING TO USES THAT OUR STOCKHOLDERS MAY NOT AGREE WITH AND IN WAYS THAT DO NOT INCREASE OUR PROFITS OR INCREASE OUR STOCK PRICE Our management will have considerable discretion in the application of the net proceeds received by us from this offering, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. You must rely on the judgment of our management regarding the application of the proceeds of this offering. The net proceeds may be used for corporate purposes that do not increase our profitability or increase our stock price. Pending application of the net proceeds of this offering, such proceeds may be placed in investments that fail to produce income or that could lose value. 16
INSIDERS WILL CONTINUE TO HAVE SUBSTANTIAL CONTROL OVER OUR COMPANY AFTER THIS OFFERING AND COULD DELAY OR PREVENT A CHANGE IN CORPORATE CONTROL Upon completion of this offering, our executive officers and directors, and their respective affiliates, will beneficially own, in the aggregate, approximately 60.0% of our outstanding common stock. As a result, these stockholders will be able to exert significant control over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. This voting power could delay or prevent an acquisition of our company on terms that other stockholders may desire. 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. 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. Please see "Description of Capital Stock-Anti-Takeover Effects" for more information concerning these anti-takeover provisions. OUR STOCK PRICE MAY BE VOLATILE, AND YOU MAY NOT BE ABLE TO RESELL YOUR SHARES AT OR ABOVE THE INITIAL PUBLIC OFFERING PRICE There has been no public market for our common stock prior to this offering. The initial public offering price for our common stock will be determined through negotiations among the underwriters, the selling stockholders and us. This initial public offering price may vary from the market price of our common stock after the offering. If you purchase shares of common stock, you may not be able to resell those shares at or above the initial public offering price. The market price of our common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including the following: - 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 those that design, manufacture and/or sell semiconductors; - 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 customers; - departures of key personnel; and - sales of our common stock in the future. 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. OF OUR TOTAL OUTSTANDING SHARES AFTER THIS OFFERING, 43,378,118, OR 93%, WILL BE RESTRICTED FROM IMMEDIATE RESALE BUT MAY BE SOLD INTO THE MARKET IN THE NEAR FUTURE. THIS COULD CAUSE THE MARKET PRICE OF OUR COMMON STOCK TO DROP SIGNIFICANTLY, EVEN IF OUR BUSINESS IS DOING WELL After this offering, we will have outstanding 46,578,118 shares of common stock, based on the number of shares outstanding at January 1, 2000. This includes the 2,720,000 shares we are selling, and the 480,000 shares the stockholders are selling, in this offering, all of which shares may be resold in the public market 17
immediately. The remaining 43,378,118 shares will become available for resale in the public market as shown in the chart below: % OF TOTAL SHARES NUMBER OF SHARES OUTSTANDING DATE OF AVAILABILITY FOR RESALE INTO THE PUBLIC MARKET - - --------------------- ----------------- ------------------------------------------------------------ 0 -- Immediately. 12,954,470 27.8% 120 days after the date of this prospectus due to a release of 30% of the shares, and shares underlying the options, held by each stockholder from lock-up agreements with the underwriters, if the last reported sale price of our common stock is at least two times the initial public offering price per share for each of the 20 consecutive trading days preceding the 120th day after the date of this prospectus and other conditions are met. 27,508,907 59.1% 181 days after the date of this prospectus upon the expiration of the lock-up agreements with the underwriters (plus any shares not already released from the lock-up agreements). 2,914,741 6.3% At various times after 181 days following the date of this prospectus, subject to compliance with federal securities laws and upon the lapse of any applicable vesting restrictions. The underwriters can waive the restrictions of the lock-up agreements at an earlier time without prior notice or announcement and allow stockholders to sell their shares. As restrictions on resale end, the market price of our stock could drop significantly if the holders of restricted shares sell them or are perceived by the market as intending to sell them. In addition, the sale of these shares could impair our ability to raise capital through the sale of additional stock. For more detailed information, see "Shares Eligible for Future Sale." SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS This prospectus contains forward-looking statements that involve substantial risks and uncertainties. You can identify these statements by forward-looking words such as "may," "will," "expect," "intend," "anticipate," "believe," "estimate" and "continue" and other similar words. You should read statements that contain these words carefully because they discuss our future expectations, make projections of our future results of operations or of our financial condition or state other "forward-looking" information. We believe that it is important to communicate our future expectations to our investors. However, there may be events in the future that we are not able to accurately predict or control. The factors listed in the sections captioned "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations," as well as any cautionary language in this prospectus, provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. Before you invest in our common stock, you should be aware that the occurrence of the events described in the "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections and elsewhere in this prospectus could have a material adverse effect on our business, operating results and financial condition. 18
USE OF PROCEEDS Assuming an initial public offering price of $22.00 per share, we will receive $54.7 million from our sale of 2,720,000 shares of common stock and the selling stockholders in this offering will receive $9.8 million from their sale of 480,000 shares of common stock, net of estimated offering expenses payable by us and estimated underwriting discounts and commissions. We will not receive any portion of the net proceeds received by the selling stockholders from the sale of their shares. If the underwriters exercise their over-allotment option in full, we will receive an additional $9.8 million in net proceeds. See "Principal and Selling Stockholders." The principal purposes of this offering are to increase our equity capital, create a public market for our common stock, facilitate future access by us to public capital markets and provide us with increased visibility in our markets. We intend to use the net proceeds for this offering for working capital and other general corporate purposes, including capital expenditures and research and development. Although we may use a portion of the net proceeds to acquire businesses, products or technologies that are complementary to our current or future business and product lines, we currently have no specific acquisitions planned. Our management will have significant flexibility in applying the net proceeds of this offering. Pending such uses, we will invest the net proceeds of this offering in investment grade, interest-bearing securities. DIVIDEND POLICY We have never declared or paid any cash dividends on our common stock and we do not intend to pay cash dividends in the foreseeable future. We currently expect to retain any future earnings to fund the operation and expansion of our business. In addition, our credit agreements with our bank lender prohibit us from paying cash dividends on our capital stock without the prior consent of the lender. 19
CAPITALIZATION The following table sets forth our capitalization as of January 1, 2000: - On an actual basis; - On a pro forma basis to reflect the conversion of all shares of our outstanding convertible preferred stock into 13,842,174 shares of common stock; and - On a pro forma as adjusted basis to additionally reflect our sale of 2,720,000 shares of common stock in this offering at an assumed initial public offering price of $22.00 per share, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. You should read the following table in conjunction with the section captioned "Management's Discussion and Analysis of Financial Condition and Results of Operation" of this prospectus and our consolidated financial statements and the notes to those statements included at the end of this prospectus.

DILUTION Our pro forma net tangible book value as of January 1, 2000 was approximately $20.8 million, or $.47 per share of common stock. Pro forma net tangible book value per share represents the amount of our total tangible assets reduced by the amount of our total liabilities, divided by 43,858,118 shares of common stock outstanding on a pro forma basis as of January 1, 2000. These pro forma numbers reflect the conversion of all shares of our outstanding convertible preferred stock into common stock. Dilution in pro forma net tangible book value per share to new investors represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the pro forma net tangible book value per share of common stock immediately after the completion of this offering. After giving effect to our sale of 2,720,000 shares of common stock in this offering at an assumed initial public offering price of $22.00 per share and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, our adjusted pro forma net tangible book value as of January 1, 2000 would have been $75.4 million, or $1.62 per share. This amount represents an immediate increase in pro forma net tangible book value to our existing stockholders of $1.15 per share and an immediate dilution to new investors of $20.38 per share. The following table illustrates this per share dilution: Assumed initial public offering price per share............. $ 22.00 Pro forma net tangible book value per share at January 1, 2000.................................................... $ .47 Increase in pro forma net tangible book value per share attributable to new investors........................... 1.15 ------- Pro forma net tangible book value per share after this offering.................................................. 1.62 ------- Dilution per share to new investors......................... 20.38 ======= If the underwriters exercise their over-allotment option in full, our adjusted pro forma net tangible book value at January 1, 2000 would have been $85.2 million, or $1.81 per share, representing an immediate increase in pro forma net tangible book value to our existing stockholders of $1.34 per share and an immediate dilution to new investors of $20.19 per share. The following table summarizes, on a pro forma basis as of January 1, 2000, the differences between the number of shares of common stock purchased from us, the aggregate cash consideration paid to us and the average price per share paid by our existing stockholders and by new investors purchasing shares of common stock in this offering. These pro forma numbers reflect the conversion of all of our outstanding convertible preferred stock into common stock. The calculation below is based on an assumed initial public offering price of $22.00 per share, before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us: SHARES PURCHASED TOTAL CONSIDERATION AVERAGE --------------------- ---------------------- PRICE PER NUMBER PERCENT AMOUNT PERCENT SHARE ---------- -------- ----------- -------- --------- Existing stockholders....................... 43,858,118 94.2% $15,096,695 20.1% $ .34 New investors............................... 2,720,000 5.8 59,840,000 79.9 22.00 ---------- ----- ----------- ----- Total............................... 46,578,118 100.0% $74,936,695 100.0% ========== ===== =========== ===== This discussion and table assume no exercise of any stock options or warrants outstanding as of January 1, 2000. As of January 1, 2000, there were options outstanding to purchase a total of 2,380,226 shares of common stock with a weighted average exercise price of $2.52 per share and warrants outstanding to purchase a total of 143,182 shares of common stock with a weighted average exercise price of $1.17 per share. To the extent that any of these options or warrants are exercised, there will be further dilution to new investors. If the underwriters' over-allotment option is exercised in full, the number of shares held by new investors will increase to 3,200,000 shares, or 6.8% of the total number of shares of common stock outstanding after this offering. 21

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH THE CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES WHICH APPEAR ELSEWHERE IN THIS PROSPECTUS. THE FOLLOWING DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF VARIOUS FACTORS, INCLUDING THOSE DISCUSSED BELOW AND ELSEWHERE IN THIS PROSPECTUS, PARTICULARLY UNDER THE HEADING "RISK FACTORS." PLEASE ALSO SEE "SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS." OUR FISCAL YEAR-END FINANCIAL REPORTING PERIODS ARE A 52- OR 53- WEEK YEAR ENDING ON THE SATURDAY CLOSEST TO DECEMBER 31ST. FISCAL 1997 HAD 53 WEEKS AND ENDED ON JANUARY 3, 1998. FISCAL 1998 HAD 52 WEEKS AND ENDED ON JANUARY 2, 1999. FISCAL 1999 HAD 52 WEEKS AND ENDED ON JANUARY 1, 2000. ALL OF THE QUARTERLY PERIODS REPORTED IN THIS PROSPECTUS HAD THIRTEEN WEEKS. OVERVIEW We design and develop proprietary, analog-intensive, mixed-signal ICs for the rapidly growing communications industry. Our innovative ICs can dramatically reduce the cost, size and system power requirements of the products that our customers sell to their end-user customers. We currently offer ICs that can be incorporated into communications devices, such as modems and cellular phones, as well as cable and satellite set-top boxes, credit card verification machines, automated teller machines, network access equipment and remote gaming devices. Our five largest customers in fiscal 1999 were Intel, Motorola, PC-Tel, SmartLink and 3Com. Our company was founded in 1996. Our business has grown rapidly since our inception, as reflected by our employee headcount, which increased to 148 at the end of fiscal 1999, from 42 at the end of fiscal 1998 and 17 at the end of fiscal 1997. As a "fabless" semiconductor company, we rely on third-party semiconductor fabricators 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-party assemblers to assemble and package these die prior to final product testing and shipping. Our company is organized into two principal divisions, the Wireline Products Division and the Wireless Products Division. Our Wireline Products Division commenced research and development for our first IC product, the direct access arrangement, or DAA, in October 1996. We introduced our DAA product in the first quarter of fiscal 1998, and first received acceptance of this product for inclusion in a customer's device, which we refer to as a "design win", in March 1998. The first commercial shipment of our DAA product was made in April 1998. In September 1998, we introduced an international version of our first DAA product. Based on the success of our DAA products, we became profitable in the fourth quarter of fiscal 1998 and have been profitable in each succeeding quarter through the quarter ended January 1, 2000. Substantially all of our sales to date have been derived from sales of our various DAA products and we expect to remain dependent on continued sales of DAA products for a majority of our sales until we are able to diversify sales with new products. In fiscal 1999, our Wireline Products Division introduced two additional ICs, a voice codec product, which encodes analog signals within the voice frequency range into digital signals and decodes digital voice signals back into analog signals, and our ISO modem product. In addition, our Wireless Products Division introduced our RF synthesizer product in fiscal 1999. In January 2000, our Wireline Products Division introduced our ProSLIC product. We will be less dependent on our DAA products for future sales to the extent that these products, or other products that we may introduce, are incorporated into devices sold by our customers. For a further description of our products, please see "Business--Products." Since our inception, a few customers have accounted for a substantial portion of our sales. During fiscal 1999, our three largest customers accounted for 84% of our sales, including 62% for PC-Tel, 12% for SmartLink and 10% for 3Com. In fiscal 1998, PC-Tel accounted for 78% and 3Com accounted for 20% of our sales. No other customer accounted for more than 10% of our sales in either of these years. To date, substantially all of our sales have been generated through our direct sales force. In fiscal 1998, we began to 23
establish a network of independent sales representatives and distributors worldwide to support our sales and marketing activities. We anticipate that sales to these representatives and distributors will increase as a percentage of our sales in future periods. However, we expect to continue to experience significant customer concentration in direct sales to key customer accounts until we are able to diversify sales with new customers. The percentage of our sales to customers located outside of the United States was 7% in fiscal 1999 and insignificant in fiscal 1998. All of our sales to date have been denominated in U.S. dollars. We believe that a greater percentage of our sales will be made to customers outside of the United States as our products receive greater acceptance in international markets. The sales cycle for the test and evaluation of our ICs can range from 1 to 12 months or more. An additional 3 to 6 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. We intend to continue to increase our investment in research and development, selling, general and administrative functions and inventory as we expand our operations in the future. 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. Our limited operating history and rapid growth makes it difficult for us to assess the impact of seasonal factors on our business. Because many of our ICs are designed for use in consumer products such as PCs and cellular 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. We expect to experience seasonal fluctuations in the demand for our products as customer demand increases in greater volume across our product offerings. The following describes the line items set forth in our consolidated statements of income: SALES. Sales consists of revenue generated principally by sales of our ICs. Generally, we recognize sales at the time of shipment to our customers. Sales are deferred on shipments to distributors until they are resold by such distributors. Our products typically carry a one-year warranty. Since our inception, product returns and warranty costs have been immaterial. Our sales 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 sales were conducted 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 or in response to competition. In addition, as a product matures, we expect that the average selling price for that product will decline. Therefore, our ability to increase sales in the future is dependent on increased demand for our established products and our ability to ship larger volumes of products in response to such demand, as well as customer acceptance of newly introduced products. COST OF GOODS SOLD. Cost of goods sold 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; an allocated portion of our occupancy costs; and allocable depreciation of testing equipment. Generally, we depreciate equipment over four years on a straight line basis. We also depreciate our leasehold improvements over the applicable lease term. Recently introduced products tend to have higher cost of goods sold 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 semiconductor fabricators and assemblers achieve greater economies of scale for that product. Additionally, the cost of wafer procurement, which is a significant component of cost of goods sold, varies cyclically with overall demand for semiconductors. The 24
semiconductor industry has recently experienced a period of high demand, resulting in higher wafer procurement costs. RESEARCH AND DEVELOPMENT. Research and development expense consists primarily of compensation and related costs of employees engaged in research and development activities, as well as an allocated portion of our occupancy costs for such operations. We depreciate our research and development equipment over four years and amortize our purchased software from computer-aided design tool vendors over four years. Development activities include the creation of test methodologies to assure compliance with required specifications. We have granted stock options or directly issued stock to patent attorneys and outside technical consultants for services previously rendered. We recognize stock-based compensation expense for these non-employees based on the deemed fair value of the options or stock at the date of grant. 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, other promotional and marketing expenses and reserves for bad debt. Write-offs of bad debt have been insignificant to date. We awarded non-employee sales persons with stock in connection with a sales incentive program that ended on January 1, 2000. We recognize stock-based compensation expense based on the deemed fair value of the stock at the date of grant. AMORTIZATION OF DEFERRED STOCK COMPENSATION. In connection with the grant of stock options and direct issuances of stock to our employees, we recorded deferred stock compensation of approximately $16.3 million, representing, for accounting purposes, the difference between the deemed fair value of the common stock and the respective exercise prices at the date of grant in the case of stock options and the fair market value of the stock at the date of grant in the case of direct issuances of stock. The difference is amortized over the vesting period of the applicable option or share, generally five to eight years, resulting in amortization expense of $975,000 and $8,000 for fiscal 1999 and 1998, respectively. The amortization of deferred stock compensation is recorded as an operating expense. INTEREST INCOME. Interest income reflects interest earned on average cash and cash equivalents and investment balances. INTEREST EXPENSE. Interest expense consists of interest on our long-term debt and capital lease obligations. INCOME TAX EXPENSE. We accrue a provision for federal and state income tax at the applicable statutory rates. 25
RESULTS OF OPERATIONS The following table sets forth our statement of income data as a percentage of sales for fiscal 1998 and 1999. We have not presented percentage data for fiscal 1997 since we had no sales in fiscal 1997. FISCAL FISCAL 1998 1999 -------- -------- Sales...................................................... 100.0 % 100.0% Cost of goods sold......................................... 42.3 33.6 ----- ----- Gross profit............................................... 57.7 66.4 Operating expenses: Research and development................................. 81.8 17.7 Selling, general and administrative...................... 37.4 15.4 Amortization of deferred stock compensation.............. .1 2.1 ----- ----- Total operating expenses............................... 119.3 35.2 ----- ----- Operating income (loss)....................................

(60.6) 30.6 Income tax expense......................................... -- 7.1 ----- ----- Net income (loss).......................................... (60.6)% 23.5% ===== ===== COMPARISON OF FISCAL 1999 TO FISCAL 1998 SALES. Sales increased $41.3 million, or 736.4%, to $46.9 million in fiscal 1999 from $5.6 million in fiscal 1998. The increase was attributable to the strong acceptance of our DAA family of products, including our international DAA and MC-97 DAA products. This increase reflected an increase in the number of customers that purchased our IC products and an increase in the volume that those customers bought. GROSS PROFIT. Cost of goods sold increased $13.4 million, or 565.1%, to $15.8 million in fiscal 1999 from $2.4 million in fiscal 1998, and represented 33.6% of sales in fiscal 1999 and 42.3% of sales in fiscal 1998, respectively. Gross profit increased $27.9 million, or 861.7%, to $31.1 million in fiscal 1999 from $3.2 million in fiscal 1998. Gross margins improved to 66.4% in fiscal 1999 from 57.7% in fiscal 1998. The increase in gross profit was primarily due to the substantial increase in sales volume. The improvement in gross margin from fiscal 1998 to 1999 was due to volume discounts on wafer purchases that resulted from substantial increases in our production and attractive pricing conditions for silicon wafers due to the availability of capacity within the semiconductor manufacturing industry during the period. Our gross margins may decline due to the expected introduction of products competitive to our products and increased demand for silicon wafer capacity within the semiconductor industry generally. However, the impact of these factors on our gross margins may be offset by increased sales of newly introduced products, which we expect will have larger gross margins than products which have been in the market for longer periods of time and that face greater competition as a result. RESEARCH AND DEVELOPMENT. Research and development expense increased $3.7 million or 80.9%, to $8.3 million in fiscal 1999 from $4.6 million in fiscal 1998, and represented 17.7% of sales in fiscal 1999 and 81.8% of sales in fiscal 1998. The increased research and development expense was principally due to continued product development activities in the Wireline Division, as well as significant increases in product development activity in the Wireless Division. Both divisions increased spending to develop test methodologies for new products. The substantial decrease in research and development expense as a percentage of sales reflected our emergence from the development stage with modest fiscal 1998 sales 26
compared to substantial sales growth in fiscal 1999. We expect that research and development expense will increase in absolute dollars in future periods as we develop new ICs, and may fluctuate as a percentage of sales due to significant changes in our sales volume and new product development initiatives. During fiscal 1999, we recorded approximately $196,000 of stock-based compensation expense in connection with grants of stock options and direct issuances to outside patent attorneys and technical consultants. SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative expense increased $5.1 million or 244.0%, to $7.2 million in fiscal 1999 from $2.1 million in fiscal 1998, and represented 15.4% of sales in fiscal 1999 and 37.4% of sales in fiscal 1998. The increase in the dollar amount of selling, general and administrative expense was principally attributable to increased staffing. The decrease in selling, general and administrative expense as a percentage of sales was due to substantially higher sales levels in fiscal 1999. We expect that selling, general and administrative expense will increase in absolute dollars in future periods as we expand our sales channels, marketing efforts and administrative infrastructure. We also expect our legal expenses to increase as a result of the infringement lawsuit we filed against Analog Devices and 3Com in January 2000. This lawsuit may also cause our sales to 3Com to decline. In addition, we expect selling, general and administrative expenses to fluctuate as a percentage of sales because of (1) the likelihood that indirect distribution channels, which entail the payment of commissions, will account for a larger portion of our sales in future periods and, therefore, increase our selling, general and administrative expense relative to a direct sales force performing at satisfactory levels of productivity; (2) fluctuating usage of advertising to promote our products and, in particular, our newly introduced products; and (3) potential significant variability in our future sales volume. During fiscal 1999, we recorded approximately $70,000 of stock-based compensation expense for awards of stock to non-employee sales persons in connection with a sales incentive program that ended January 1, 2000. AMORTIZATION OF DEFERRED STOCK COMPENSATION. We have recorded deferred stock compensation for the difference between the exercise price of option grants, or the issuance price of direct issuances of stock, and the deemed 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 $975,000 for fiscal 1999 and $8,000 for fiscal 1998. Our amortization expense increased in fiscal 1999 due to an increase in deferred stock compensation recorded in fiscal 1999 for options and restricted stock issued in fiscal 1999. INTEREST INCOME. Interest income was $402,000 in fiscal 1999 as compared to $261,000 in fiscal 1998. The increase in interest income was primarily due to higher cash balances invested in short-term investments. INTEREST EXPENSE. Interest expense was $699,000 in fiscal 1999 as compared to $206,000 in fiscal 1998. The increase in interest expense was primarily due to higher levels of debt and lease financing used to finance capital expenditures, relating to the acquisition of IC testing equipment and leasehold improvements. INCOME TAX EXPENSE. Our effective tax rate was 23.1% for fiscal 1999. We had sufficient net operating loss tax carryforwards available from our development stage operations to offset any tax liability during fiscal 1998. For fiscal 1999, utilization of the remaining net operating loss carryforward and, to a lesser extent, full utilization of prior and current year research and development tax credits reduced our effective tax rates from full corporate rates. We expect to pay a full corporate income tax rate of approximately 38% during future periods. COMPARISON OF FISCAL 1998 TO FISCAL 1997 SALES. Sales were $5.6 million in fiscal 1998. We did not have any sales in fiscal 1997. Sales in fiscal 1998 were attributable to the introduction of our first DAA product in March 1998. 27
GROSS PROFIT. Cost of goods sold was $2.4 million in fiscal 1998 and gross profit was $3.2 million in 1998. Gross margins were 57.7% in fiscal 1998. RESEARCH AND DEVELOPMENT. Research and development expense increased $3.2 million, or 236.3%, to $4.6 million in fiscal 1998 from $1.4 million in fiscal 1997, and represented 81.8% of sales in fiscal 1998. The increase in the dollar amount of research and development expense was primarily due to increased engineering staffing from 10 to 20 people, in addition to product development expenses related to the release of our first product. SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative expense increased $1.5 million, or 234.1%, to $2.1 million in fiscal 1998 from $627,000 in fiscal 1997, and represented 37.4% of sales in fiscal 1998. The increase in the dollar amount of selling, general and administrative expense was principally attributable to increased staffing, moving and relocation expenses and provisions for bad debt reserves on initial product shipments. AMORTIZATION OF DEFERRED STOCK COMPENSATION. Amortization of deferred stock compensation expense was $8,000 in fiscal 1998. No deferred stock compensation expense was recorded in fiscal 1997. INTEREST INCOME. Interest income was $261,000 in fiscal 1998 as compared to $178,000 in fiscal 1997. The increase in interest income was primarily due to higher invested cash balances on average during the period. INTEREST EXPENSE. Interest expense was $206,000 in fiscal 1998, compared to $22,000 in fiscal 1997. The increase in interest expense was primarily due to higher levels of debt and lease financing related to the various financing lines. The proceeds of such lines were used to finance capital expenditures, consisting principally of acquisitions of IC testing equipment, computer-aided design software tools and leasehold improvements. INCOME TAX EXPENSE. We did not incur liabilities for income taxes in fiscal 1997 or fiscal 1998 due primarily to operating losses incurred in each of those years. 28
QUARTERLY RESULTS OF OPERATIONS The following tables set forth our unaudited statement of operations data for each of the eight quarters in the period ended January 1, 2000, as well as such data expressed as a percentage of our sales for the quarters presented. This unaudited quarterly information has been prepared on the same basis as our audited financial statements and, in the opinion of our management, reflects all normal recurring adjustments that we consider necessary for a fair presentation of the information for the periods presented. Operating results for any quarter are not necessarily indicative of results for any future period. Because our sales during the first and second quarters of fiscal 1998 were immaterial, data regarding quarterly operations for such periods as a percentage of sales has been excluded from the table below.

Our quarterly results of operations have varied from quarter-to-quarter in the past and we expect them to vary from quarter-to-quarter in future periods. These changes are principally due to (1) the timing and volume of orders from our customers, (2) the timing of volume production of the products into which our ICs are incorporated and (3) the capacity and cost environment in the semiconductor industry applicable to our procurement of services from third-party foundries and assembly contractors. We have experienced declining average selling prices for our products while the costs of third-party foundries and assembly contractors have increased or decreased based on relative market demand for capacity in the semiconductor manufacturing industry. Beginning in the fourth quarter of fiscal 1998, and continuing through the first and second quarter of fiscal 1999, our sales have increased due to greater market acceptance of our DAA ICs. In the third quarter of fiscal 1999, our sales increased significantly due to an increase in demand for our international DAA product. Additionally, personal computer manufacturers began to adopt the Modem Codec 97, or MC-97, standard developed by Intel for connecting modem interface circuitry to microprocessors during this time frame. We experienced rapid sales increase in our MC-97 modem product during the third quarter of fiscal 1999 due to the adoption of this emerging standard. Such market technical standards rarely are introduced with any quarter-to-quarter regularity and can contribute to significant changes in operating results. Research and development expenses increased by $1.2 million, or 56.4%, to $3.3 million in the fourth quarter of fiscal 1999 from $2.1 million in the third quarter of fiscal 1999. This increase was principally due to new product development activity in the Wireless Division, and, to a lesser extent, continued product development in the Wireline Division. The number of employees involved in research and development increased from 41 employees at the end of the third quarter of fiscal 1999 to 62 employees at the end of the fourth quarter, representing a 51.2% increase in staffing. An active recruiting effort was underway during the quarter to increase staffing for new product development activities. This increase in research and development spending also increased as a percent of sales to 17.9% in the fourth quarter of fiscal 1999 from 14.5% of sales in the third quarter of fiscal 1999. We believe that this rapid increase in research and development staffing may not be sustainable in future quarterly periods due to the limited availability of qualified mixed-signal circuit design engineers and test development engineers. LIQUIDITY AND CAPITAL RESOURCES Our principal sources of liquidity as of January 1, 2000 consisted of $14.7 million in cash, cash equivalents and short-term investments, our bank credit facilities and equipment financing facilities with three institutional lenders. Our bank credit facilities include a revolving line of credit available for borrowings and letters of credit of up to the lesser of $3.0 million or 80% of eligible accounts receivable, a separate letter of credit facility for $454,000 related to a building lease, equipment loans which provided for initial equipment financing of up to $2.5 million and new loan facilities totaling $4.0 million for new equipment, leasehold improvements and computer-aided design software. At January 1, 2000, a letter of credit for $500,000 related to a building lease was outstanding under the revolving line of credit, with no other amounts outstanding thereunder, and $1.5 million was outstanding under the equipment loans. At January 31, 2000, $6.5 million was available under our credit facilities. Borrowings under the revolving line of credit bear interest at the bank's prime rate, which was 8.5% at January 1, 2000, and are payable at annual renewal of the line. Borrowings under the equipment loan agreement bear interest at the bank's prime rate, and are payable through January 2002. The new $4.0 million loan facilities have no amount outstanding as of January 1, 2000. We intend to use these facilities for financing principally during the first quarter of fiscal 2000. All bank facilities are secured by our accounts receivable, inventories, capital equipment and all other unsecured assets (excluding intellectual property). The line of credit, the separate letter of credit facility and equipment loans contain 30
provisions that prohibit the payment of cash dividends and require the maintenance of tangible net worth and compliance with financial ratios measured on a monthly basis. Any default on one of the bank facilities will cause all of the bank facilities to be in default under these agreements. The bank has received warrants as consideration for providing portions of this financing. We also have entered into agreements with three institutional lenders for equipment financing. Under these agreements, we may borrow up to an aggregate of $8.5 million to purchase or lease equipment, leasehold improvements and software. At January 1, 2000, borrowings under these agreements were $8.2 million. This indebtedness bears effective interest rates (including end of term interest payments of $1.1 million) ranging from 12.5% to 14.6% per annum and is secured by a security interest in specific items, principally comprised of test equipment, and is repayable over approximately the next four years. See Note 4 of the notes to our consolidated financial statements. We have funded our operations to date primarily through sales of preferred stock which have resulted in gross aggregate proceeds to us of approximately $12.8 million, and debt financing under the credit and lease obligations described above and cash from operations. During fiscal 1999, cash provided by operating activities was $12.3 million reflecting the first year of profitable operations. This compares to cash used in operating activities of $4.5 million in fiscal 1998 and $219,000 in fiscal 1997 as our company incurred operating losses, primarily as a result of our product development activities. Capital expenditures were $9.9 million in fiscal 1999, $3.1 million in fiscal 1998 and $2.3 million in fiscal 1997. These expenditures were incurred to purchase semiconductor test equipment, design software and engineering tools, and other computer equipment and software to support our business expansion. In addition, we relocated our operations to a new facility in Austin, Texas in 1999 and incurred approximately $1.0 million in capital expenditures and leasehold improvement expenses in connection with the build-out of this new location. We anticipate further capital expenditures in fiscal 2000 of approximately $14.0 million to fund test floor operations and expanded engineering product development activities. We believe the net proceeds of this offering, together with our existing cash balances, credit facilities and cash generated by our operations, will be 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. 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. Although we are currently not a party to any agreement or letter of intent with respect to a potential acquisition or strategic arrangement, we may enter into acquisitions or strategic arrangements in the future which also could require us to seek additional equity or debt financing. There can be no assurances that additional equity or debt financing, if required, will be available to us on acceptable terms or at all. RECENT ACCOUNTING PRONOUNCEMENTS In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133 is effective for fiscal years beginning after June 15, 2000. SFAS No. 133 requires that all derivative instruments be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income. We do not expect that the adoption of SFAS No. 133 will have a material impact on our financial statements because we do not currently hold any derivative instruments. In December 1999, the Securities and Exchange Commission staff released Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements, which provides guidance on the recognition, presentation and disclosure of revenue in financial statements. The application of SAB No. 101 did not have a material impact on our financial statements. 31
On March 31, 1999, the FASB issued an exposure draft entitled "Accounting for Certain Transactions Involving Stock Compensation," which is a proposed interpretation of APB Opinion No. 25 which has an effective date for certain transactions of December 15, 1998. However, the exposure draft has not been finalized. Once finalized and issued, the current accounting practices for transactions involving stock compensation may need to change and such changes could affect our future earnings. QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK 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. Due to the nature of our short-term investments, we have concluded that there is no material market risk exposure. 32
BUSINESS We are a leader in the design and development of proprietary, analog-intensive, mixed-signal integrated circuits, or ICs, for the rapidly growing global communications industry. Mixed-signal ICs are electronic components that convert real-world analog signals, such as sound and radio waves, into digital signals that electronic products can process. Therefore, mixed-signal ICs are critical components of numerous communications products, including cellular phones, cable and satellite set-top boxes, modems and fax machines. To develop our business rapidly, we initially focused our efforts on developing ICs for the personal computer modem market. We are now applying our mixed-signal and communications expertise to the development of ICs for other high growth communications devices such as cellular telephones and network access applications. Our world-class, mixed-signal design engineers use standard complementary metal oxide semiconductor, or CMOS, technology to create innovative ICs that can dramatically reduce the cost, size and system power requirements of devices that our customers sell to their end-user customers. Our expertise in analog CMOS and mixed-signal IC design allows us to develop new and innovative products rapidly, which enables our customers to improve their time-to-market with end products that respond to consumer demand in the communications industry. Our five largest customers in fiscal 1999 were Intel, Motorola, PC-Tel, SmartLink and 3Com. INDUSTRY BACKGROUND According to Dataquest, the overall worldwide analog and mixed-signal IC market, which includes as a subset the mixed-signal communications IC markets that we target, surpassed $21.2 billion in 1998 and is expected to grow to more than $39.1 billion by 2003. This growth is being driven in part by the demand for communications services, which has increased at a rapid rate in recent years due to a number of factors, including the growth of Internet usage, development of new communications technologies, availability of improved communications services at lower costs and remote access requirements for corporate networks. This demand has fueled tremendous growth in the number of wireless and wireline communications devices used to access these services. For example, in wireless markets, the demand for cellular phones and other wireless devices, such as pagers and personal digital assistants, has grown rapidly as digital wireless services have become increasingly popular and affordable. In wireline markets, demand has increased for communications capabilities in a wide range of products, including personal computers, cable set-top boxes, fax machines, credit card verification machines, automated teller machines and remote gaming systems. Digital communications devices typically require mixed-signal circuits that provide analog-to-digital functionality to access the communications networks to which they are connected. Traditional designs for communications devices have used mixed-signal circuits built with numerous discrete analog and digital components. While these traditional designs provide the required functionality, they can be inefficient and inadequate for use in markets where size, price and performance are increasingly important product differentiators. In order to improve their competitive position, communications device manufacturers need advanced mixed-signal ICs that reduce the number of discrete components and required board space to create smaller products with improved price/performance characteristics. Additionally, these manufacturers require programmable ICs that can be reconfigured to comply with numerous and constantly evolving international communications standards without altering the fundamental design of a product. Manufacturers of communications devices face accelerating time-to-market demands and must adapt to evolving industry standards and new technologies. Because analog-intensive, mixed-signal IC design expertise is difficult to find, these manufacturers increasingly are turning to third parties to provide advanced mixed-signal ICs. Designing the analog component of a mixed-signal IC involves great complexity and difficulty, because the performance of an analog IC depends on the creative analog expertise of engineers to maximize speed, power, amplitude and resolution within the constraints of standard manufacturing processes. The development of analog design expertise typically requires years of 33
practical analog design experience under the guidance of a senior engineer, and engineers with the required level of skill and expertise are in short supply. Many third-party IC providers lack sufficient analog expertise to develop compelling mixed-signal ICs. As a result, manufacturers of communications devices are often faced with inadequate mixed-signal ICs and are challenged to find third-party providers that can supply them with mixed-signal ICs with greater functionality, smaller size and lower power requirements all at a reduced cost and time-to-market. THE SILICON LABORATORIES SOLUTION Our engineers apply their expertise in analog and mixed-signal IC design to create analog-intensive, mixed-signal ICs that communications device manufacturers use in numerous leading-edge applications. We combine this analog and mixed-signal expertise with standard CMOS manufacturing process technology to develop innovative mixed-signal ICs for our customers. We are a fabless semiconductor company and rely on leading semiconductor foundries to produce our ICs, which allows us to focus our resources on enhancing and extending our core design capabilities. Our ICs provide our customers with the following benefits: DRAMATICALLY IMPROVED SIZE AND PRICE/PERFORMANCE CHARACTERISTICS. Our products are highly integrated, typically replacing existing alternatives that use multiple costly discrete components, and use standard CMOS manufacturing process technology, which typically is less expensive than other competing technologies. As a result, we can offer competitively priced products that allow our customers to reduce the number of discrete components used in their products while offering increased reliability, lower power consumption, and smaller sizes. Additionally, some of our ICs can be programmed to accommodate emerging and differing global standards. REDUCED TIME REQUIRED TO BRING A PRODUCT TO MARKET. We enable our customers to rapidly meet the demand for their end-user communications devices by providing them with outsourced mixed-signal ICs that incorporate our industry-leading designs. Because we design our ICs to be integrated into the products of multiple manufacturers and we conduct extensive research and development to ensure that our products conform to evolving technical standards, our customers are able to rapidly integrate our products into their designs. By reducing the number of discrete components, our customers can also reduce the number of outside suppliers required for their products. As a result, our customers can reduce the time required to bring a communication device to market. Furthermore, our ICs are tested prior to customer delivery to ensure their compliance with applicable specifications of the Federal Communications Commission, or FCC, and international regulators, minimizing complications and delays for our customers throughout their internal testing process. ATTRACTIVE NEW PRODUCT OPPORTUNITIES. Our space-saving and cost-efficient ICs allow our customers to create smaller and more cost-effective products for use in numerous emerging communications markets. Our ICs provide enhanced communication capabilities at lower costs and with smaller form factors for numerous evolving applications, including cellular communications, Internet telephony and remote monitoring systems. For example, due to the dramatically reduced size and cost of our silicon DAA products, our customers are able to cost-effectively incorporate modems into multiple new applications such as remote gaming systems, smart vending machines and set-top boxes. STRATEGY Our objective is to be a leading supplier of proprietary analog-intensive mixed-signal ICs for the communications industry. To achieve this goal, we are pursuing the following strategies: TARGET MULTIPLE HIGH-GROWTH COMMUNICATIONS MARKETS. We intend to continue to identify large and sustainable opportunities in emerging high-growth communications markets and develop mixed-signal ICs that address the needs of suppliers of communications devices in those markets. We strive to develop 34
creative IC that require complex analog design in order to address opportunities with high revenue and profit potential and relatively long life-cycles. Our core technological capabilities were initially focused on the PC modem market and we are currently applying these capabilities to expand into other high growth communications markets such as cellular phones, set-top boxes, central office lines, interactive gaming systems and personal digital assistants. LEVERAGE OUR EXISTING DESIGNS TO OFFER COMPELLING PRODUCTS. We consider our ability to leverage our proprietary IC designs a competitive advantage. Many of our designs are reusable in the development of new mixed-signal. By leveraging these designs and our extensive experience, we are able to rapidly introduce new analog-intensive, mixed-signal ICs that are smaller in size and require less power in the final device than traditional products. We enable our customers to reduce production costs, board space and the number of processes required for the manufacture of their devices while improving yields, performance and reliability. For example, our silicon direct access arrangement product was introduced in 1998, and has already been modified for use in our ISOmodems and adapted for use with our voice codec products. We intend to continue to use our existing IC designs and methodologies as building blocks for new ICs to rapidly address new and emerging market opportunities. ATTRACT AND RETAIN TOP MIXED-SIGNAL TECHNICAL TALENT. We are committed to recruiting and retaining technical personnel who possess the expertise necessary to identify compelling market opportunities for highly innovative mixed-signal ICs and to design, develop and market these ICs to capitalize on those opportunities. We believe we have assembled a world-class team of engineers with the exceptional analog design expertise required to provide our customers with products that offer superior price/performance characteristics. We believe our senior engineer expertise, combined with our focus on leading-edge technology and innovative products to complex problems, enhances our attractive and highly stimulating collaborative work environment. We believe this appealing work environment provides us with a competitive advantage in recruiting. We intend to continue to promote this attractive work environment and to offer competitive compensation to attract and retain the best mixed-signal IC technical talent available. CAPITALIZE ON STANDARD MANUFACTURING PROCESSES AND FABLESS SEMICONDUCTOR MODEL. High volume CMOS manufacturing process technology is widely available at semiconductor foundries around the world. We intend to continue to utilize standard CMOS manufacturing process technology to develop advanced mixed-signal ICs that can be reliably manufactured in volume and decrease the time-to-market of our new products at a significant cost advantage. Our fabless model allows us to focus our resources on the development of proprietary and innovative mixed-signal designs, while minimizing capital and operating infrastructure requirements. EXTEND TECHNOLOGICAL LEADERSHIP. We believe that we have established a reputation as a technological leader in the design and development of analog-intensive mixed-signal ICs. We are actively extending our intellectual property position by aggressively investing in research and development and utilizing our mixed-signal expertise to create innovative ICs. We currently hold one U.S. patent, with 56 U.S. patent applications pending, and we continue to actively pursue the filing of additional patent applications to cover our intellectual property advancements. We intend to leverage our talent pool of engineers, and continue to invest significant resources in recruiting and developing expertise in mixed-signal IC design to extend our proprietary intellectual property portfolio. EXPAND GLOBAL SALES EFFORTS. We plan to aggressively pursue a global multi-channel distribution strategy. We believe there are significant international opportunities for both our wireline and wireless ICs and we intend to continue to expand our global marketing and distribution efforts to address the range of markets and applications for our innovative mixed-signal ICs. While substantially all of our sales in fiscal 1999 were made to customers based in the United States, we intend to increase our international sales through our international direct sales office and our network of independent sales representatives and distributors. 35
PRODUCTS We provide mixed-signal ICs for use in both wireline and wireless communications devices and applications. Our products integrate the numerous discrete components required by most existing mixed-signal circuits for communications devices into single chips or chipsets. By doing so, we are able to create products that: - require less board space; - can offer superior performance; - provide increased reliability; - reduce system power requirements; and - reduce costs. WIRELINE PRODUCTS Many of our wireline products are designed for use in analog modems, which enable the transmission of digital data signals over wireline telephone networks and are used in the vast majority of Internet connections. Three fundamental components of the modem provide the requisite functionality: software algorithms; a direct access arrangement, or DAA; and an analog/digital converter, or codec. Complex software algorithms mitigate the impairments found in the telephone network, such as noise interference and echoes. Since the telephone lines fundamentally transmit analog signals, and computers use digital transmissions, modems require analog-to-digital and digital-to-analog converters, or coders/decoders, that are referred to as codecs. A modem transmits analog signals from a codec to the telephone line through a DAA. We offer a variety of modem products which include the DAA and codec functions and which are software programmable to meet international regulatory specifications. - DAA FUNCTIONS. Government regulation requires electrical isolation between the telephone line and the local electrical power system. Isolation is required for safety, superior sound quality, and to prevent harm to the telephone network from electrical surges. With the introduction of telecommunications deregulation, consumers were allowed to connect directly to the telephone network. However, they were required to use a device that met FCC part 68 specifications, which govern all electronic products sold in the United States intended for connection to the telephone network. Traditional DAA products met FCC requirements, but were designed inefficiently and contained a variety of discrete components. Our silicon DAA is the first to integrate the bulky transformer, relays, and opto-isolators traditionally found in a modem's isolation circuitry, and achieve FCC part 68 compliance. Our silicon DAA may be used with digital signal processors, or DSPs, currently used in traditional analog modems. We were able to design our product in CMOS, creating a silicon DAA with attractive process characteristics for our customers. Our DAA products are lower in cost, use substantially less board space than alternative products, and are programmable to meet international standards. - CODEC FUNCTIONS. Traditionally, analog modems included specialized hardware chips known as a digital signal processor, or DSP, which contained a modem's software algorithms. The DSP is typically the most expensive hardware component in traditional analog modems. In an effort to reduce costs and as a result of capabilities offered by more powerful microprocessors introduced during the mid-1990's, a new generation of modems, known as soft modems, has evolved. When soft modems are used, the main microprocessor in a personal computer runs the software algorithms required to run a modem, thus eliminating the need for a DSP chip. The software modem's digital interface between the codec and the personal computer in a soft modem can take one of two forms. The first and most popular is the PCI interface standard. Soft modems using a PCI interface typically require an additional chip to make the digital codec interface compatible with a PCI 36
interface. Alternatively, the MC-97, a new modem interface standard promoted by Intel, eliminates the need for this additional chip. With an MC-97 compliant codec, soft modem hardware can interface directly with a microprocessor, further reducing costs. Our DAA products, which include codecs, can be used with either the PCI or MC-97 interface standards. We also design innovative products for network access applications. In January 2000, we announced the ProSLIC, our first product targeting this market. - SUBSCRIBER LINE INTERFACE CIRCUIT, OR SLIC. SLICs provide the analog telephone interface on the source end of the telephone line. The primary functions of a SLIC are to ring and provide power and signaling (such as caller ID, dial tone and busy tone) to the telephone. Traditionally, SLICs have been produced with an expensive high voltage IC accompanied by a CMOS codec IC and requiring as many as five voltage sources. Our ProSLIC has been designed as one integrated CMOS chip, eliminating the need for a high voltage IC and requiring only two voltage sources. The result is a smaller, more reliable and less expensive product. The following table summarizes the ICs for the wireline market that we currently offer to customers: WIRELINE PRODUCTS (INTRODUCTION DATE) DESCRIPTION APPLICATIONS Direct Access Provides both the functionality of a DAA and - personal computer modems Arrangement (DAA) a codec. A DAA provides electrical isolation - fax machines between a wireline device, such as a modem, - host modems (First Quarter 1998) and the telephone line to guard against - handheld organizers power surges in the telephone line, while a - set-top boxes codec provides analog-to-digital and digital-to-analog conversion.

The most popular standard used today is the Global System for Mobile Communications, or GSM, standard, which was first deployed in Europe and is now available in several countries throughout the world. Manufacturers continue to introduce new cellular phone models that offer smaller form factors and longer battery life at lower costs. These market dynamics drive a need for new highly integrated electronics that reduce component count and consume less power. Our products are designed to serve this need. 38
The following table summarizes the ICs for the wireless market that we currently offer to customers: WIRELESS PRODUCTS (INTRODUCTION DATE) DESCRIPTION APPLICATIONS RF Synthesizer for A frequency synthesizer generates high - wireless local area networking General Application frequency signals that are used in wireless - wireless modems communications systems to select a - wireless meter readers (Fourth Quarter 1999) particular radio channel. Existing frequency - handheld point-of-sale synthesizers contain discrete voltage terminals control modules and as many as 30 discrete electronic components to provide functionality comparable to what we provide in a monolithic IC.

RF Synthesizer for GSM Provides the same functionality as the RF - GSM cellular phones Synthesizer for General Application but has - GPRS data communications (Fourth Quarter 1999) been optimized for cellular phones operating devices on the GSM standard. This synthesizer is capable of providing dual-band synthesis to use one or both of the separate radio bands available to GSM phones. Additionally, this synthesizer has very fast settling times, allowing the phone to quickly lock to a desired channel. This RF synthesizer is compatible with General Packet Radio Service, or GPRS standard, which is the data communications protocol employed by the GSM standard. GPRS brings wireless Internet access to GSM users through data transfer and signaling over GSM radio networks. CUSTOMERS, SALES AND MARKETING We market our products to original equipment manufacturers and other providers of applications in both the wireline and wireless communications markets. The following is a list of customers that have purchased our products and incorporated them into products or devices offered to their customers: Ambient Motorola 3Com Intel PC-Tel Topic Lucent SmartLink Zyxel To date, we have sold substantially all of our ICs through our direct sales force. We maintain three sales offices in North America and conduct European direct sales through our United Kingdom subsidiary. Our direct sales force includes regional sales managers in the field and area business managers at our headquarters to further support customer communications. Many of these managers have engineering degrees. Our password-protected field sales organization Web site, which includes technical documentation, backlog information, order status, product availability and new product introduction information, supports communications with our field sales organization. Additionally, we provide direct communication to all field sales personnel as part of a structured sales communications program. 39
We also utilize independent sales representatives and distributors to generate sales of our products. We have relationships with many independent sales representatives and distributors worldwide whom we have selected based on their understanding of the mixed-signal IC marketplace and their ability to provide effective field sales support for our products. To date, sales to these representatives and distributors have accounted for a small portion of our sales. Our marketing efforts are targeted at both identified industry leaders and emerging market participants. Marketing activities are supported by a focused communications effort that targets editorial coverage in leading trade and business publications. Our external Web site includes data sheets and supporting product information, press releases and a company overview. These activities, in conjunction with customer contacts, help prompt requests for evaluation boards and sample products, which are fulfilled through our corporate headquarters as an integrated part of our sales efforts. Due to the complex and innovative nature of our ICs, we employ experienced applications engineers who work closely with each customer to support the design-win process, and can significantly accelerate the customer's time required to bring a product to market. A design-win occurs when a customer has designed our ICs into its product architecture. A considerable amount of effort to assist the customer in incorporating our ICs into its products typically is required prior to any sale. In many cases, our innovative ICs require significantly different implementations than existing approaches and, therefore, successful implementations may require extensive communication with potential customers. The amount of time required to achieve a design-win can vary substantially depending on a customer's development cycle, which can be relatively short (such as three months) or very long (such as two years) based on a wide variety of customer factors. Due to this extensive design-win process, once a completed design architecture has been implemented and produced in high volumes, our customers are reluctant to significantly alter their designs. We believe this promotes relatively long product life cycles for our ICs and high barriers to entry for competitive products, even at lower price levels for such competing products. Finally, our close collaboration with our customers provides us with knowledge of derivative product ideas or completely new product line offerings that may not otherwise arise in other new product discussions. RESEARCH AND DEVELOPMENT Through our research and development efforts, we apply our world-class analog and mixed-signal engineering talent and expertise to create new ICs that integrate functions typically performed inefficiently by multiple discrete components. This integration generally results in lower costs, smaller die sizes, lower power demands and enhanced price/performance characteristics. We attempt to reuse successful techniques for integration in new applications where similar benefits can be realized. Reliable and precise analog and mixed-signal ICs can only be developed by teams of engineers under the direction of senior engineers with significant analog experience who are familiar with the intricacies of designing these ICs for commercial volume production. The development of test methodologies is a critical activity in releasing a new product for commercial success. We believe that we have attracted some of the best engineers in our industry. As of January 1, 2000, we had 62 employees involved in research and development. TECHNOLOGY Our product development process facilitates the design of highly innovative mixed-signal ICs . Our senior engineers start the product development process by forming an understanding of our customers' products and then design alternatives for decreasing power, size and cost requirements. Our engineers' deep knowledge of existing and emerging communications standards and performance requirements help us to assess the technical feasibility of a particular IC. We target areas where Silicon Laboratories can provide compelling product improvements. Once we have solved the primary challenges, our field engineers continue to work closely with our customers' design teams to maintain and develop an understanding of our customers' needs, allowing us to formulate derivative products and features. In providing mixed-signal ICs for our customers, we believe our key competitive advantages are: (1) analog CMOS design expertise; (2) digital signal processing design expertise; and (3) our broad understanding of communication systems technology and trends. To fully capitalize on these advantages, 40
we have assembled a world-class development team with exceptional analog and mixed-signal design expertise led by accomplished senior engineers. ANALOG CMOS DESIGN EXPERTISE We believe that our most significant core competency is our world-class analog design capability. Additionally, we strive to design all of our ICs in CMOS processes. There are several modern process technologies for manufacturing semiconductors including CMOS, Bipolar, BiCMOS, silicon germanium and gallium arsenide. While it is significantly more difficult to design analog ICs in CMOS, CMOS provides multiple benefits versus existing alternatives including significantly reduced cost, reduced technology risk and greater worldwide foundry capacity. CMOS is the most commonly used process technology for manufacturing digital ICs and as a result is most likely to be used for the manufacturing of ICs with finer line geometries, which enable smaller and faster ICs. By designing our ICs in CMOS, we enable our products to benefit from this trend towards finer line geometries, which lowers the cost of the digital circuitry in our products. Designing analog ICs is significantly more complicated than designing digital ICs. While advanced software tools exist to help automate digital IC design, there are far fewer tools for advanced analog IC design. In many cases, our pioneering efforts in analog circuit design begin at the fundamental transistor level. We believe that we have a demonstrated ability to design the most difficult analog and RF circuits using standard CMOS technologies. For example, our DAA product family replaces expensive, discrete modem components, such as transformers, relays and opto-isolators, with highly integrated CMOS mixed-signal ICs. Similarly, expensive cellular phone components such as oscillators are replaced by our integrated CMOS frequency synthesizer products. DIGITAL SIGNAL PROCESSING DESIGN EXPERTISE We consider the partitioning of a circuit's functionality to be a proprietary and creative design technique. Our digital signal processing design expertise maximizes the price/performance characteristics of both the analog and digital functions and allows our ICs to work in an optimized manner to accomplish particular tasks. Generally, we surround core analog circuitry with inexpensive digital CMOS transistors, which allows our ICs to perform the required analog functions with increased digital capabilities. For example, our ProSLIC product is designed to function more efficiently than traditional products for the source end of the telephone line which involve a two chip combination requiring more board space and numerous external components. The ProSLIC product is partitioned by combining a core analog design that provides analog-to-digital conversion and digital-to-analog conversion with optimized digital signal processing functions such as data compression, data expansion, filtering and tone generation. In this manner, we can isolate the higher voltage required to ring a telephone in low-cost, off-chip high voltage transistors, thereby enabling us to fulfill the remaining core functions with a single chip. UNDERSTANDING OF COMMUNICATION SYSTEMS TECHNOLOGY AND TRENDS Our expertise and focus on communications ICs is rooted in our founders' previous experience at AT&T Bell Labs working in CMOS design for communications applications. This expertise, which we consider a competitive advantage, is the foundation of our in-depth understanding of the technology and trends that impact communications systems and markets. Therefore, we believe we have a unique ability to predict product evolution and design compelling ICs for communications manufacturers. Our understanding of the role of analog/digital interfaces within communications systems and the key domestic and international telecommunications standards that must be supported are particular areas of expertise. MANUFACTURING As a fabless IC manufacturer, we conduct IC design and development in our facilities in the United States and electronically transfer our proprietary IC designs to third-party semiconductor fabricators who process silicon wafers to produce the ICs that we design. Our IC designs use industry-standard complementary metal oxide semiconductor, or CMOS, manufacturing process technology to achieve a level of performance normally associated with more expensive special purpose IC fabrication technology. We believe the use of CMOS technology facilitates the rapid production of our ICs within a lower cost 41
framework. Our IC production employs submicron process geometries which are readily available from leading foundry suppliers worldwide, thus ensuring the availability of manufacturing capability over our products' life cycles. We currently rely solely on Taiwan Semiconductor Manufacturing Co. to manufacture all of our semiconductor wafers. We are in the process of qualifying Vanguard International Semiconductor, an affiliate of Taiwan Semiconductor Manufacturing Co., as an additional semiconductor fabricator and such qualification is not complete. In anticipation of successfully qualifying Vanguard, Vanguard is currently producing a majority of our current work in progress. Once the silicon wafers have been produced, they are shipped directly to our third-party assembly subcontractors. The assembled ICs are then forwarded for final testing, either at our facilities or through outsourced testing vendors, prior to shipping to our customers. We believe that our fabless manufacturing model significantly reduces our capital requirements and allows us to focus our resources on the design, development and marketing of our ICs. COMPETITION The markets for semiconductors generally, and for analog and mixed-signal ICs in particular, are intensely competitive. We believe the principal competitive factors in our industry are: - - - level of integration; - intellectual property; - - - product capabilities; - customer support; - - - reliability; - reputation; and - - - price; - ability to rapidly introduce new products to market. We believe that we are competitive with respect to these factors, particularly because our ICs typically are smaller in size, are highly integrated, achieve high performance specifications at lower price points than competitive products and are manufactured in standard CMOS which generally enables us to supply them on a relatively rapid basis to customers to meet their product introduction schedules. Our DAA product is an example of our competitive positioning. Traditional DAA isolation techniques rely on relays, optical isolators and transformers, transfer analog signals across the isolation barrier, and/or require numerous external components to achieve their functionality. Our silicon DAA reduces costs by eliminating the need for these bulky and/or numerous discrete components. Our DAA ICs also reduce board area and power consumption, while improving performance. However, disadvantages we face in our markets include our short operating history and the need for customers to redesign their products and modify their software to implement our ICs in their products. We anticipate 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 wireline and wireless communications markets and applications, we face competition from a relatively large number of competitors. Across our product offerings, we compete with Advanced Micro Devices, Analog Devices, Conexant, Delta Integration, Fujitsu, Infineon Technologies, Krypton Isolation, National Semiconductor, Philips and Texas Instruments, among 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. In addition, our customers could develop products or technologies internally that would replace their need for our products and would become a source of competition. As the markets for communications products grow, we also may face competition from traditional communication device companies. These companies may enter the mixed-signal semiconductor market by introducing their own products, including components within their products that would eliminate the need for our ICs, or entering into strategic relationships with or acquiring other existing IC providers. Many of our competitors and potential competitors have longer operating histories, greater name recognition, access to larger customer bases and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than us. Current and potential competitors have established or may establish financial and strategic relationships between themselves or with existing or 42
potential customers, resellers or other third parties. Accordingly, it is possible that new competitors or alliances among competitors could emerge and rapidly acquire significant market share. INTELLECTUAL PROPERTY Our future success depends in part upon our proprietary technology. We seek to protect our technology through a combination of patents, copyrights, trade secrets, trademarks and confidentiality procedures. As of January 1, 2000, we had been granted one United States patent in the IC field, which is entitled "Analog Isolation System With Digital Communication Across A Capacitive Barrier" and expires in 2016. The patent covers a silicon DAA chipset which provides a digital, low-cost interface to telephone lines. We also have filed 56 additional U.S. patent applications. There can be no assurance that patents will ever be issued for these applications. Furthermore, it is possible that any patents held by us may be invalidated, circumvented, challenged or licensed to others. In addition, there can be no assurance that such patents will provide us with competitive advantages or adequately safeguard our proprietary rights. In addition, we claim copyright protection for proprietary documentation used in our products. We register the visual image of each IC that we manufacture in commercial quantities with the United States Copyright Office. We have registered the Silicon Laboratories logo as a trademark in the United States. All other trademarks, service marks or trade names appearing in this prospectus are the property of their respective owners. We also attempt to protect our trade secrets and other proprietary information through agreements with our customers, suppliers, employees and consultants, and through other security measures. We intend to protect our rights vigorously, but there can be no assurance that our efforts will be successful. In addition, the laws of other countries in which our products are sold may not protect our products and intellectual property rights to the same extent as the laws of the United States. While our ability to effectively compete depends in large part on our ability to protect our intellectual property, we believe that our technical expertise and ability to introduce new products in a timely manner will be an important factor in maintaining our competitive position. Many participants in the semiconductor and communications industries have a significant number of patents and have frequently demonstrated a readiness to commence litigation based on allegations of patent and other intellectual property infringement. From time to time, third parties may assert infringement claims against us. We may not prevail in any such litigation or may not be able to license any valid and infringed patents from third parties on commercially reasonable terms, if at all. Litigation, regardless of the outcome, is likely to result in substantial cost and diversion of our resources, including our management's time. Any such litigation could materially adversely affect us. Other than industry standard licenses with our vendors, such as wafer fabrication tool libraries, computer-aided design applications and business software applications, we do not have material licenses. EMPLOYEES As of January 1, 2000, we employed 148 people, including 34 in manufacturing, 62 in engineering development, 30 in marketing, 12 in sales and 10 in administration. Our success depends on the continued service of our key technical and senior management personnel and on our ability to continue to attract, retain and motivate highly skilled analog and mixed-signal engineers. The competition for such personnel is intense. We have never had a work stoppage and none of our employees are represented by a labor organization. We consider our employee relations to be good. FACILITIES Our main executive, administrative and technical offices occupy approximately 37,800 square feet in Austin, Texas under a lease that expires in April 2006, with one five year renewal option. We have an additional lease commitment in Austin, Texas for supplemental office space for approximately 34,000 square feet with expected occupancy to commence in February 2000. This lease's term is for 76 months after initial occupancy with one five year renewal option. We believe that these facilities are sufficient to 43
meet our needs through December 2000. We also lease sales offices in Atlanta, Georgia and San Jose, California. LEGAL PROCEEDINGS On January 12, 2000, we filed a lawsuit against Analog Devices and 3Com in the United States District Court for the Western District of Texas (Austin Division). The complaint asserts that Analog Devices has infringed, and is continuing to infringe, our U.S. Patent 5,870,046, entitled "Analog Isolation System With Digital Communication Across A Capacitive Barrier," by making, using, selling, offering to sell and/or importing silicon DAAs that embody or use inventions claimed by our patent. The complaint also asserts, among other things, that Analog Devices and 3Com have misappropriated our confidential information, know-how and trade secrets relating to our DAA technology, tortiously interfered with our business relations with our existing and prospective customers, and been unjustly enriched by this misappropriation. The suit seeks unspecified damages from Analog Devices, including damages for willful infringement of our patent, and an injunction prohibiting Analog Devices from infringing our patent. In addition, the suit seeks unspecified damages, including punitive damages and attorneys' fees arising, among other things, out of the misappropriation, tortious interference and unjust enrichment, and an injunction prohibiting designing, manufacturing, reproducing, using or selling any ICs, modems or other products the conception, design or development of which was based on our confidential information, know-how and trade secrets. On January 25, 2000, Analog Devices filed an answer denying that it has misappropriated our confidential information, know-how and trade secrets and brought a counterclaim against us seeking a declaratory judgment that our issued U.S. patent is invalid and unenforceable and that Analog Devices has not infringed our issued U.S. patent. The counterclaim further alleges that we improperly failed to disclose a relevant pre-existing patent to the U.S. Patent and Trademark Office during the course of our patent application process, and that we therefore are unable to enforce our patent. We filed an answer to Analog Devices' counterclaim asserting that our issued U.S. patent is valid and enforceable and that Analog Devices has infringed our issued U.S. patent. We also denied that we improperly excluded any relevant information in the course of our patent application process. 3Com has not yet filed a response to our lawsuit. However, we expect that 3Com will file an answer during the next ten days. For a description of risks associated with this pending lawsuit, please see "Risk Factors--We depend on a limited number of customers for the vast majority of our sales, and the loss of, or a significant reduction in orders from, any key customer could significantly reduce our sales" and "--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." We are not currently involved in any other material legal proceedings. 44

Gay..................................... 150,000 46,019 157 20,000 Vice President of Sales OPTION GRANTS IN LAST FISCAL YEAR The following table provides information concerning individual grants of stock options made during fiscal 1999 to each of our executive officers named in the Summary Compensation Table. The percentage of total options granted to our employees in the last fiscal year is based on options granted to purchase an aggregate of 2,484,200 shares of common stock during fiscal 1999. We have never granted any stock appreciation rights. The exercise prices represent our board's estimate of the fair market value of the common stock on the grant date. In establishing these prices, our board considered many factors, including our financial condition and operating results, transactions involving the issuances of shares of our preferred stock, the senior rights and preferences accorded issued shares of preferred stock, and the market for comparable stocks. We granted these options under our 1997 Stock Option/Stock Issuance Plan. Each option has a maximum term of ten years, subject to earlier termination if the optionee's services are terminated. Except as otherwise noted, these options are immediately exercisable, but we have the right to repurchase at the exercise price any shares that have not vested. If we are acquired in a stockholder-approved transaction by merger, consolidation or asset sale, the option shares will accelerate in full unless the option is assumed by the successor corporation and our repurchase rights with respect to the unvested option shares are assigned to such corporation. In the event that the option is so assumed by, and our repurchase rights with respect to unvested shares are assigned to, the successor corporation and, within 18 months following the acquisition, the optionee's position is reduced to a lesser position or the optionee's employment is involuntarily terminated, the option shares will accelerate and become fully vested. The amounts shown as potential realizable value represent hypothetical gains that could be achieved for the respective options if exercised at the end of the option term. These amounts represent assumed rates of appreciation in the value of our common stock from the fair market value on the date of grant. 48
The 5% and 10% assumed annual rates of compounded stock price appreciation are mandated by rules of the Securities and Exchange Commission and do not represent our estimate or projection of the future price of our common stock. Actual gains, if any, on stock option exercises depend on the future performance of the trading price of our common stock. The amounts reflected in the table may not necessarily be achieved. The following table sets forth information concerning the individual grants of stock options to each of our named executive officers in fiscal 1999.

These options vest as to 20% on the first anniversary of the date of grant and vest as to the remaining 80% in equal monthly installments over the following 48 months. FISCAL YEAR-END OPTION VALUES The following table provides information about stock options held as of January 1, 2000 by each of our executive officers named in the Summary Compensation Table. The value realized by Mr. Gay is based on the difference between the fair market value of the shares on the date of purchase, as determined by our board of directors, and the price paid for such shares. There was no public trading market for our common stock as of January 1, 2000. Accordingly, we have based the value of unexercised in-the-money options at January 1, 2000 on an assumed initial public offering price of $22.00 per share, less the applicable exercise price per share, multiplied by the number of shares underlying the options. Actual gains on exercise, if any, will depend on the value of our common stock on the date on which the shares are sold.

2000 STOCK INCENTIVE PLAN The 2000 Stock Incentive Plan is intended to serve as the successor equity incentive program to our 1997 Stock Option/Stock Issuance Plan. The 2000 Stock Incentive Plan became effective upon its adoption by the board of directors on January 5, 2000; it will be approved by the stockholders prior to the date of this offering. We have reserved 5,389,498 shares of our common stock for issuance under the 2000 Stock Incentive Plan. This share reserve consists of the shares which were available for issuance under the predecessor plan on the effective date of the 2000 Stock Incentive Plan plus an additional increase of 2,000,000 shares. The share reserve will automatically be increased on the first trading day of January each calendar year, beginning in January 2001, by a number of shares equal to 2% of the total number of shares of our common stock outstanding on the last trading day of the immediately preceding calendar year, but no such annual increase will exceed 1,000,000 shares. The share reserve will also increase by the number of shares repurchased by the Company, at the original exercise or issue price, pursuant to its repurchase rights under the predecessor plan but such increase will not exceed 3,357,204 shares. In no event may any one participant in the 2000 Stock Incentive Plan receive option grants or direct stock issuances for more than 1,000,000 shares in the aggregate per calendar year. Outstanding options under the predecessor plan will be incorporated into the 2000 Stock Incentive Plan upon the date of this offering, and no further option grants will be made under that plan. The incorporated options will continue to be governed by their existing terms, unless the compensation committee extends one or more features of the 2000 Stock Incentive Plan to those options. However, except as otherwise noted below, the outstanding options under the predecessor plan contain substantially the same terms and conditions summarized below for the discretionary option grant program under the 2000 Stock Incentive Plan. The 2000 Stock Incentive Plan has four separate programs: - the discretionary option grant program under which eligible individuals in our employ or service (including officers, non-employee board members and consultants) may be granted options to purchase shares of our common stock; - the stock issuance program under which such individuals may be issued shares of common stock directly, through the purchase of such shares or as a bonus tied to the performance of services; - the salary investment option grant program under which executive officers and other highly compensated employees may elect to apply a portion of their base salary to the acquisition of special below-market stock option grants; and - the automatic option grant program under which option grants will automatically be made at periodic intervals to eligible non-employee board members. The discretionary option grant and stock issuance programs will be administered by our compensation committee. This committee will determine which eligible individuals are to receive option grants or stock issuances, the time or times when such option grants or stock issuances are to be made, the number of shares subject to each such grant or issuance, the exercise or purchase price for each such grant or issuance (which may be less than, equal to or greater than the fair market value of the shares), the status of any granted option as either an incentive stock option or a non-statutory stock option under the federal tax laws, the vesting schedule to be in effect for the option grant or stock issuance and the maximum term for which any granted option is to remain outstanding. The committee will also select the executive officers and other highly compensated employees who may participate in the salary investment option grant program in the event that program is activated for one or more calendar years. Neither the compensation committee nor the board will exercise any administrative discretion with respect to option grants made 50
under the salary investment option grant program or under the automatic option grant program for the non-employee board members. The exercise price for the options may be paid in cash or in shares of our common stock valued at fair market value on the exercise date. The option also may be exercised through a same-day sale program without any cash outlay by the optionee. In addition, the compensation committee may allow a participant to pay the option exercise price or direct issue price (and any associated withholding taxes incurred in connection with the acquisition of shares) with a full-recourse, interest-bearing promissory note. In the event that the company is acquired, whether by merger or asset sale or board-approved sale by the stockholders of more than 50% of our voting stock, each outstanding option under the discretionary option grant program which is not to be assumed by the successor corporation or otherwise continued will automatically accelerate in full, and all unvested shares under the discretionary option grant and stock issuance programs will immediately vest, except to the extent the repurchase rights with respect to those shares are to be assigned to the successor corporation or otherwise continued in effect. The compensation committee may grant options and issue shares which will accelerate (1) in the acquisition even if the options are assumed and repurchase rights assigned, (2) in connection with a hostile change in control (effected through a successful tender offer for more than 50% of our outstanding voting stock or by proxy contest for the election of board members), or (3) upon a termination of the individual's service following a change in control or hostile take-over. In the event of an acquisition of the company (by merger or asset sale), options currently outstanding under the 1997 plan will accelerate unless assumed by the successor corporation; and all assumed options will accelerate upon the optionee's involuntary termination (including a forced resignation) within 18 months following the acquisition. Such options are not by their terms subject to acceleration in connection with any other change in control or hostile take-over. Stock appreciation rights may be issued under the discretionary option grant program which will provide the holders with the election to surrender their outstanding options for an appreciation distribution from the company equal to the fair market value of the vested shares subject to the surrendered option less the aggregate exercise price payable for such shares. Such appreciation distribution may be made in cash or in shares of common stock. There are currently no outstanding stock appreciation rights under the predecessor plan. The compensation committee has the authority to cancel outstanding options under the discretionary option grant program (including options incorporated from predecessor plan) in return for the grant of new options for the same or different number of option shares with an exercise price per share based upon the fair market value of the common stock on the new grant date. In the event the compensation committee elects to activate the salary investment option grant program for one or more calendar years, each executive officer and each other highly compensated employee selected for participation may elect to reduce his or her base salary for that calendar year by a specified dollar amount not less than $5,000 nor more than $50,000. In return, the individual will automatically be granted, on the first trading day in the calendar year for which the salary reduction is to be in effect, a non-statutory option to purchase that number of shares of common stock determined by dividing the salary reduction amount by two-thirds of the fair market value per share of our common stock on the grant date. The option exercise price will be equal to one-third of the fair market value of the option shares on the grant date. As a result, the fair market value of the option shares on the grant date less the exercise price payable for those shares will be equal to the salary reduction amount. The option will become exercisable in a series of 12 equal monthly installments over the calendar year for which the salary reduction is to be in effect and will be subject to full and immediate vesting in the event of an acquisition or change in control of the company. 51
Under the automatic option grant program, each individual who is serving as a non-employee member of our board of directors on the date the underwriting agreement for this offering is executed will receive an option for 30,000 shares of our common stock with an exercise price equal to the price at which shares are sold in this offering, provided such individual has not been in our prior employ. Each individual who first joins the board after the effective date of this offering as a non-employee board member will automatically be granted an option for 30,000 shares of our common stock at the time of his or her commencement of board service; provided such individual has not been in our prior employ. In addition, on the date of each annual stockholders meeting, beginning with the 2001 meeting, each individual who has served as a non-employee board member for at least six months and is to continue to do so will receive an option grant to purchase 5,000 shares of common stock. Each automatic grant will have an exercise price equal to the fair market value per share of our common stock on the grant date and will have a maximum term of 10 years, subject to earlier termination following the optionee's cessation of board service. Each option will be immediately exercisable, subject to our right to repurchase any unvested shares, at the original exercise price, at the time of the board member's cessation of service. Each 30,000-share option grant will vest, and the repurchase right will lapse, in a series of four equal successive annual installments upon the optionee's completion of each year of board service over the four-year period measured from the grant date. Each 5,000-share option grant will vest, and the repurchase right will lapse, upon the optionee's completion of one year of board service measured from the grant date. However, each such outstanding option will immediately vest upon a change in control, a hostile take-over or the death or disability of the optionee while serving as a board member. Limited stock appreciation rights will automatically be included as part of each grant made under the automatic option grant and salary investment option grant programs and may be granted to one or more officers as part of their option grants under the discretionary option grant program. Options with such a limited stock appreciation right may be surrendered to us upon the successful completion of a hostile tender offer for more than 50% of our outstanding voting stock. In return for the surrendered option, the optionee will be entitled to a cash distribution from us in an amount per surrendered option share equal to the highest price per share of common stock paid in connection with the tender offer less the exercise price payable for such share. The board may amend of modify the 2000 Stock Incentive Plan at any time, subject to any required stockholder approval. The 2000 Stock Incentive Plan will terminate no later than January 4, 2010. EMPLOYEE STOCK PURCHASE PLAN Our Employee Stock Purchase Plan was adopted by the board on January 5, 2000 and will be approved by the stockholders prior to the date of this offering. The plan will become effective immediately upon the execution of the underwriting agreement for this offering. The plan is designed to allow eligible employees to purchase shares of common stock, at semi-annual intervals, through their periodic payroll deductions. A total of 400,000 shares of our common stock will initially be issued under the plan. The share reserve will automatically increase on the first trading day of January each year beginning in January 2001, by 0.5% of the total shares of common stock outstanding on the last trading day of the immediately preceding calendar year, but no such annual increase will exceed 250,000 shares. In no event, however, may any participant purchase more than 200 shares, nor may all participants in the aggregate purchase more than 75,000 shares on any one semi-annual purchase date. The plan will have a series of successive offering periods, each with a maximum duration of 24 months. However, the initial offering period will begin on the day the underwriting agreement is executed in connection with this offering and will end on the last business day in April 2002. The next offering period will begin on the first business day in May 2002, and subsequent offering periods will be set by the compensation committee. Shares will be purchased for the participants semi-annually (the last business day of April and October each year) during the offering period. The first purchase date will occur on October 31, 2000. Should the fair market value of the common stock on any semi-annual purchase date 52
be less than the fair market value on the first day of the offering period, then the current offering period will automatically end and a new offering period will begin, based on the lower fair market value. Individuals who are eligible employees on the start date of any offering period may enter the plan on that start date or on any subsequent semi-annual entry date (generally May 1 or November 1 each year). Individuals who become eligible employees after the start date of the offering period may join the plan on any subsequent semi-annual entry date within that period. A participant may contribute up to 15% of his or her base salary through payroll deductions and the accumulated payroll deductions will be applied to the purchase of shares on the participant's behalf on each semi-annual purchase date. The purchase price per share will be 85% of the lower of the fair market value of our common stock on the participant's entry date into the offering period or the fair market value on the semi-annual purchase date. The board may at any time amend or modify the plan. The plan will terminate no later than the last business day in April 2010. 53
CERTAIN TRANSACTIONS PRIVATE PLACEMENTS OF EQUITY 5% STOCKHOLDERS, DIRECTORS AND EXECUTIVE OFFICERS. Since our inception in August 1996, we have raised capital primarily through the sale of our preferred stock, including the following sales to holders of more than 5% of our outstanding common stock, directors and executive officers: In March and June 1997, we sold shares of our Series A preferred stock at a price of $0.98214425 per share to the following: - 3,818,177 shares to funds affiliated with Austin Ventures - 254,545 shares to Silverton Partners - 254,545 shares to H. Berry Cash Concurrently with the closing of the financing, investment funds affiliated with Austin Ventures became a 5% stockholder. In addition, William P. Wood, a general partner of Silverton Partners and some investment funds affiliated with Austin Ventures, and a special limited partner of other funds associated with Austin Ventures, and H. Berry Cash became members of our board of directors. In June 1998, we sold shares of our Series B preferred stock at a price of $4.76 per share to the following. - 423,451 shares to funds affiliated with Austin Ventures - 28,230 shares to Silverton Partners - 21,009 shares to H. Berry Cash - 42,017 shares to Berry and Dianne Cash Grandchildrens' Trust - 52,522 shares to Jonathan D. Ivester, our Vice President of Manufacturing Although the number of shares of Series A and Series B preferred stock outstanding was not affected by the 2-for-1 split of our common stock, as a result of this stock split, each share of Series A and Series B preferred stock automatically adjusted and became convertible into two shares of our common stock. OTHER TRANSACTIONS REGISTRATION RIGHTS. For more information on registration rights we have granted to our 5% stockholders and other stockholders, please see "Description of Capital Stock--Registration Rights." LOANS TO EXECUTIVE OFFICERS. In June 1998, we loaned $56,500 to Edmund G. Healy, our Vice President/General Manager Wireless Products Division, to allow him to purchase shares of our common stock. Mr. Healy delivered a full-recourse promissory note to us with respect to his loan and the promissory note is secured by the purchased shares and accrues interest at a rate of 5.69% per annum, compounded semi-annually. As of January 1, 2000, the outstanding indebtedness on such note was $61,406, which was the largest aggregate amount of indebtedness outstanding during fiscal 1999. This promissory note becomes due in June 2003. STOCK OPTIONS GRANTED TO DIRECTORS AND EXECUTIVE OFFICERS. For more information regarding the grant of stock options to directors and executive officers, please see "Management--Director Compensation" and "--Executive Compensation." INDEMNIFICATION AND INSURANCE. Our bylaws require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law. We have entered into indemnification agreements with all of our directors and executive officers and have purchased directors' and officers' liability insurance. In addition, our certificate of incorporation limits the personal liability of our board members for breaches by the directors of their fiduciary duties. 54

DESCRIPTION OF CAPITAL STOCK Upon completion of this offering, our authorized capital stock will consist of 250,000,000 shares of common stock, par value $0.0001 per share, and 10,000,000 shares of preferred stock, par value $0.0001 per share, the rights and preferences of which may be established from time to time by our board of directors. The following summary is qualified in its entirety by reference to our certificate of incorporation and bylaws, copies of which are filed as exhibits to the registration statement of which this prospectus is a part. COMMON STOCK As of January 1, 2000, there were 30,015,944 shares of common stock outstanding that were held of record by 116 stockholders. As of January 1, 2000, there were also 2,380,226 shares of common stock subject to outstanding options, all of which were immediately exercisable, and 143,182 shares subject to outstanding warrants. As of January 1, 2000, 11,910,298 shares of the outstanding common stock were unvested and subject to rights of repurchase which lapse according to a time-based vesting schedule. Of the shares unvested and subject to rights of repurchase, 7,467,000 shares will vest upon, and as a result of, the completion of this offering. Holders of our common stock are entitled to one vote per share on all matters to be voted upon by the stockholders. The holders of common stock are not entitled to cumulative voting rights with respect to the election of directors, and as a result, minority stockholders will not be able to elect directors on the basis of their votes alone. Subject to limitations under Delaware law and preferences that may apply to any outstanding shares of preferred stock, holders of common stock are entitled to receive ratably such dividends or other distributions, if any, as may be declared by our board of directors out of funds legally available therefor. In the event of our liquidation, dissolution or winding up, holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to the liquidation preference of any outstanding preferred stock. The common stock has no preemptive, conversion or other rights to subscribe for additional securities of Silicon Laboratories. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are, and all shares of common stock to be outstanding upon completion of the offering will be, validly issued, fully paid and nonassessable. The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future. PREFERRED STOCK As of January 1, 2000, there were 6,921,087 shares of preferred stock outstanding. Upon the closing of this offering, all outstanding shares of preferred stock will automatically convert into 13,842,174 shares of common stock. Our board of directors will have the authority, without further action by the stockholders, to issue up to 10,000,000 shares of preferred stock in one or more series and to designate the rights, preferences, privileges and restrictions of each such series. The issuance of preferred stock could have the effect of restricting dividends on the common stock, diluting the voting power of the common stock, impairing the liquidation rights of the common stock or delaying or preventing our change in control without further action by the stockholders. At present, we have no plans to issue any shares of preferred stock. REGISTRATION RIGHTS According to the terms of an investors' rights agreement among us and some of our stockholders, at any time after March 21, 2002, investors in our preferred stock holding an aggregate of at least two-thirds of the shares of common stock issued upon conversion of the preferred stock will be entitled to demand that we file a registration statement with respect to the registration of their shares under the Securities Act of 1933, provided that those investors request that such registration statement register the resale of at least 57
half of the outstanding shares held by them. We are not required to effect more than two such registrations or more than one such registration during any 365 day period. In addition, the holders of up to 38,023,632 shares of common stock, including Messrs. Sooch, Scott, Welland, McGovern, Cash, Silverton Partners and entities affiliated with Austin Ventures and other stockholders and warrant holders, have piggyback registration rights with respect to the future registration of shares of our common stock under the Securities Act. If we propose to register any shares of common stock under the Securities Act, the holders of shares having piggyback registration rights are entitled to receive notice of such registration and are entitled to include their shares in the registration. At any time after we become eligible to file a registration statement on Form S-3, holders of registration rights may require us to file up to three registration statements on Form S-3 under the Securities Act with respect to their shares of common stock. These registration rights are subject to conditions and limitations, including the right of the underwriters of an offering to limit the number of shares of common stock to be included in the registration. We are generally required to bear all of the expenses of all registrations under the investors' rights agreement, except underwriting discounts and commissions. The investors' rights agreement also contains our commitment to indemnify the holders of registration rights for certain losses they may incur in connection with registrations under the agreement. Registration of any of the shares of common stock held by security holders with registration rights would result in those shares becoming freely tradeable without restriction under the Securities Act. ANTI-TAKEOVER EFFECTS Provisions of Delaware law, our certificate of incorporation, our bylaws and contracts to which we are a party, could have the effect of delaying or preventing a third party from acquiring us, even if the acquisition would benefit our stockholders. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and in the policies formulated by the board of directors and to discourage types of transactions that may involve an actual or threatened change of control of Silicon Laboratories. These provisions are designed to reduce our vulnerability to an unsolicited proposal for a takeover that does not contemplate the acquisition of all of our outstanding shares, or an unsolicited proposal for the restructuring or sale of all or part of Silicon Laboratories. DELAWARE ANTI-TAKEOVER STATUTE. We are subject to the provisions of Section 203 of the Delaware General Corporation Law, an anti-takeover law. Subject to exceptions, the statute prohibits a publicly-held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless: - Prior to such date, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; - Upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding, those shares owned (1) by persons who are directors and also officers and (2) by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or - On or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the 58
affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder. For purposes of Section 203, a "business combination" includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, with an "interested stockholder" being defined as a person who, together with affiliates and associates, owns, or within three years prior to the date of determination whether the person is an "interested stockholder," did own, 15% or more of the corporation's voting stock. In addition, provisions of our certificate of incorporation and bylaws may have an anti-takeover effect. These provisions may delay, defer or prevent a tender offer or takeover attempt of our company that a stockholder might consider in his or her best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders. The following summarizes these provisions. CLASSIFIED BOARD OF DIRECTORS. Our certificate of incorporation provides that at the first annual meeting following the closing of our initial public offering, our board of directors will be divided into three classes of directors, as nearly equal in size as is practicable, serving staggered three-year terms. As a result, approximately one-third of the board of directors will be elected each year. These provisions, when coupled with the provisions of our certificate of incorporation and bylaws authorizing our board of directors to fill vacant directorships or increase the size of our board, may deter a stockholder from removing incumbent directors and simultaneously gaining control of the board of directors. STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS. Our certificate of incorporation eliminates the ability of stockholders to act by written consent. Our bylaws provide that special meetings of our stockholders may be called only by a majority of our board of directors. ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDERS PROPOSALS AND DIRECTORS NOMINATIONS. Our bylaws provide that stockholders seeking to bring business before an annual meeting of stockholders, or to nominate candidates for election as directors at an annual meeting of stockholders, must provide us with timely written notice of their proposal. To be timely, a stockholder's notice must be delivered to or mailed and received at our principal executive offices not less than 120 days before the date in the current year that corresponds to the date we released the notice of annual meeting to stockholders in connection with the previous year's annual meeting. If, however, no meeting was held in the prior year or the date of the annual meeting has been changed by more than 30 days from the date contemplated in the notice of annual meeting, notice by the stockholder in order to be timely must be received a reasonable time before we release the notice of annual meeting to stockholders. Our bylaws also specify requirements as to the form and content of a stockholder's notice. These provisions may preclude stockholders from bringing matters before an annual meeting of stockholders or from making nominations for directors at an annual meeting of stockholders. AUTHORIZED BUT UNISSUED SHARES. Our authorized but unissued shares of common stock and preferred stock are available for our board to issue without stockholder approval. We may use these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of our authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control of our company by means of a proxy context, tender offer, merger or other transaction. SUPERMAJORITY VOTE PROVISIONS. The Delaware General Corporate Law provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation's certificate of incorporation or bylaws, unless a corporation's certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our certificate of incorporation includes supermajority vote provisions that require the affirmative vote of the holders of at least two-thirds of the combined voting power of all then-outstanding shares of our voting capital stock in order to amend the 59
provisions of our certificate of incorporation relating to the classified board of directors and the elimination of action by written consent of stockholders. INDEMNIFICATION. Our bylaws require us to indemnify our directors and officers to the fullest extent permitted by Delaware law. We have entered into indemnification agreements with all of our directors and executive officers and have purchased directors' and executive officers' liability insurance. In addition, our certificate of incorporation limits the personal liability of our board members for breaches by the directors of their fiduciary duties to the fullest extent permitted under Delaware law. TRANSFER AGENT AND REGISTRAR The transfer agent and registrar for our common stock is EquiServe Trust Company and its address is 150 Royall Street, Canton, MA 02021. NASDAQ NATIONAL MARKET LISTING We have applied to list our stock on the Nasdaq National Market under the trading symbol "SLAB." 60
SHARES ELIGIBLE FOR FUTURE SALE If our stockholders sell substantial amounts of our common stock in the public market following this offering, the prevailing market price of our common stock could decline. Furthermore, because we do not expect any shares will be available for sale for at least 120 days after the date of this prospectus as a result of contractual and legal restrictions on resale described below, sales of substantial amounts of our common stock in the public market after these restrictions lapse could adversely affect the prevailing market price and our ability to raise equity capital in the future. Upon the closing of this offering, we will have outstanding an aggregate of 46,578,118 shares of our common stock, based upon the number of shares outstanding at January 1, 2000 and assuming no exercise of the underwriters' over-allotment option and no exercise of outstanding options and warrants and no grant of additional options or warrants. Of these shares, all shares sold in this offering will be freely tradeable without restriction or further registration under the Securities Act unless they are purchased by our "affiliates," as that term is defined in Rule 144 under the Securities Act. The remaining shares will be eligible for sale in the public market as follows: NUMBER OF SHARES DATE - - ---------------- -------------------------------------------------------- 0............................. Immediately. 12,954,470............................ 120 days after the date of this prospectus due to a release of 30% of the shares, and shares underlying options, held by each stockholder from lock-up agreements with the underwriters if the conditions described below under "--Lock-up Agreements" are satisfied. 27,508,907............................ 181 days after the date of this prospectus upon the expiration of the lock-up agreements with the underwriters (plus any shares not already released from the lock-up agreements). 2,914,741............................ At various times after 181 days following the date of this prospectus, subject to compliance with securities laws and upon the lapse of any applicable vesting restrictions. LOCK-UP AGREEMENTS. All of our directors, officers, stockholders, option holders and warrant holders have signed lock-up agreements under which they have agreed not to transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock for 180 days after the date of this prospectus. If the last reported sale price of our common stock is at least two times the initial public offering price per share for each of the 20 trading days preceding the 120th day after the date of this prospectus, then 30% of the shares, and shares underlying options, held by each stockholder on the date of this prospectus shall be released from the 180 day restrictions. This early release shall occur: (a) on the 120th day after the date of this prospectus if we make a public release of our quarterly or annual results during the period beginning on the eleventh trading day after the date of this prospectus and ending on the day prior to the 120th day after the date of this prospectus, or (b) otherwise, on the second trading day after the first public release of our quarterly or annual results occurring on or after the 120th day after the date of this prospectus. Morgan Stanley & Co. Incorporated may, in its sole discretion, at any time and without prior notice or announcement, release all or any portion of shares subject to the lock-up agreements. RULE 144. In general, under Rule 144 as currently in effect, beginning 90 days after the date of this prospectus, a person who has beneficially owned shares of our common stock for at least one year, including the holding period of prior owners other than affiliates, is entitled to sell within any three-month period a number of shares that does not exceed the greater of (a) 1% of the number of shares of our common stock then outstanding, which will equal approximately 465,782 shares immediately after the 61
offering, or (b) the average weekly trading volume of our common stock on the Nasdaq National Market during the four calendar weeks preceding the filing of a notice on Form 144 with respect to that sale. Sales under Rule 144 are also subject to manner-of-sale provisions, notice requirements and the availability of current public information about us. RULE 144(K). Under Rule 144(k), a person who is not deemed to have been one of our affiliates at any time during the three months preceding a sale and who has beneficially owned shares for at least two years, including the holding period of certain prior owners other than affiliates, is entitled to sell those shares without complying with the manner of sale, public information, volume limitation or notice provisions of Rule 144. Therefore, unless otherwise restricted, Rule 144(k) shares may be sold immediately upon the closing of this offering. RULE 701. In general, under Rule 701 of the Securities Act as currently in effect, each of our directors, officers, employees, consultants or advisors who purchased shares from us before the date of this prospectus in connection with a compensatory stock plan or other written compensatory agreement is eligible to resell such shares 90 days after the effective date of this offering in reliance on Rule 144, but without compliance with restrictions, including the holding period, contained in Rule 144. REGISTRATION RIGHTS. After this offering, some holders of shares of our common stock will be entitled to rights with respect to the registration of their shares under the Securities Act. See "Description of Capital Stock--Registration Rights." After any registration of these shares, such shares will be freely tradeable without restriction under the Securities Act. These sales could cause the market price of our common stock to decline. STOCK PLANS. As of January 1, 2000, options to purchase 2,380,226 shares of common stock were outstanding under our stock option and incentive plans. After this offering, we intend to file a registration statement on Form S-8 under the Securities Act of 1933 covering shares of common stock reserved for issuance under our stock incentive plan and our employee stock purchase plan. Based on the number of options outstanding and shares reserved for issuance under our stock incentive plan and our employee stock purchase plan, the Form S-8 registration statement would cover 5,789,498 shares. The Form S-8 registration statement will become effective immediately upon filing. At that point, subject to the satisfaction of applicable exercisability periods, Rule 144 volume limitations applicable to affiliates and the agreements with the underwriters referred to above, shares of common stock to be issued upon exercise of outstanding options granted pursuant to our stock incentive plan and shares of common stock issued pursuant to our employee stock purchase plan (to the extent that such shares are not held by affiliates) will be available for immediate resale in the public market. 62
UNDERWRITERS Under the terms and subject to the conditions contained in the underwriting agreement dated the date of this prospectus, the underwriters named below, for whom Morgan Stanley & Co. Incorporated, Lehman Brothers Inc. and Salomon Smith Barney Inc. are acting as representatives, have severally agreed to purchase, and we and the selling stockholders have severally agreed to sell to them, the respective number of shares of our common stock indicated: NUMBER OF NAME SHARES - - ---- --------- Morgan Stanley & Co. Incorporated........................... Lehman Brothers Inc......................................... Salomon Smith Barney Inc.................................... --------- Total..................................................... 3,200,000 ========= The underwriters are offering the shares subject to their acceptance of the shares from us and the selling stockholders and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of common stock offered by this prospectus are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of common stock offered by this prospectus if any shares are taken. However, the underwriters are not required to take or pay for the shares covered by the over-allotment option described below. The underwriters initially propose to offer part of the shares of common stock directly to the public at the public offering price set forth on the cover page of this prospectus and part to certain dealers at a price that represents a concession not in excess of $ a share under the public offering price. Any underwriter may allow, and such dealers may reallow, a concession not in excess of $ a share to other underwriters or to certain other dealers. After the initial offering of the shares of common stock, the offering price and other selling terms may from time to time be varied by the representatives of the underwriters. We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to an aggregate of 480,000 additional shares of common stock at the public offering price listed on the cover page of this prospectus, less underwriting discounts and commissions. The underwriters may exercise such option solely for the purpose of covering over-allotments, if any, made in connection with this offering. To the extent such option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase approximately the same percentage of such additional shares of common stock as the number listed next to the underwriter's name in the preceding table bears to the total number of shares of common stock listed next to the names of all underwriters in the preceding table. If the underwriter's over-allotment option is exercised in full, the total price to public would be $ , the total underwriters' discounts and commissions would be $ and the total proceeds to us would be $ before deducting estimated offering expenses of $ . Silicon Laboratories and our directors, officers and certain other stockholders have each agreed that, without the prior written consent of Morgan Stanley & Co. Incorporated on behalf of the underwriters, during the period ending 180 days after the date of this prospectus, each of us will not, directly or indirectly: - Offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock; or 63
- Enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of common stock, whether any such transaction described above is to be settled by delivery of common stock or such other securities, in cash or otherwise. If the last reported sale price of our common stock on the Nasdaq National Market is at least twice the initial public offering per share for the 20 consecutive trading days ending on the last trading day preceding the 120th day after the date of this prospectus, 30% of the shares of our common stock subject to the 180-day restriction described above will be released from these restrictions. This early release shall occur: (a) on the 120th day after the date of this prospectus if we make a public release of our quarterly or annual results during the period beginning on the eleventh trading day after the date of this prospectus and ending on the day prior to the 120th day after the date of this prospectus, or (b) otherwise, on the second trading day after the first public release of our quarterly or annual results occurring on or after the 120th day after the date of this prospectus. The restrictions described in the previous paragraph do not apply to: - The sale of shares to the underwriters; - The issuance by Silicon Laboratories of shares of common stock upon the exercise of an option or a warrant or the conversion of a security outstanding on the date of this prospectus of which the underwriters have been advised in writing; or - Transactions by any person other than Silicon Laboratories relating to shares of common stock or other securities acquired in open market transactions after the completion of the offering of the shares of common stock. The underwriters have informed us that they do not intend sales to discretionary accounts to exceed five percent of the total number of shares of common stock offered by them. We have submitted an application to have our common stock approved for quotation on the Nasdaq National Market under the symbol "SLAB." In order to facilitate the offering of the common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriters may over-allot in connection with the offering, creating a short position in the common stock for their own account. In addition, to cover over-allotments or to stabilize the price of the common stock, the underwriters may bid for, and purchase, shares of common stock in the open market. Finally, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the common stock in the offering if the syndicate repurchases previously distributed shares of common stock in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the common stock above independent market levels. The underwriters are not required to engage in these activities and may end any of these activities at any time. We and the selling stockholders and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. DIRECTED SHARE PROGRAM At our request, the underwriters have reserved up to 320,000 shares of common stock to be sold in this offering, at the public offering price, to our customers, vendors, business associates and related persons. The number of shares of common stock available for sale to the general public will be reduced to the extent such individuals and entities purchase such reserved shares. Any reserved shares which are not so purchased will be offered by the underwriters to the general public on the same basis as the other shares. 64
PRICING OF THE OFFERING Prior to this offering, there has been no public market for the shares of common stock. Consequently, the public offering price for the shares of common stock will be determined by negotiations among us, the selling stockholders and the representatives of the underwriters. Among the factors to be considered in determining the public offering price are our record of operations, our current financial position and future prospects, the industry in general, the experience of our management, our sales, earnings and other financial and operating information in recent periods, the price-earnings ratios, price-sales ratios, market prices of securities and financial and operating information of companies engaged in activities similar to ours. The estimated initial public offering range listed on the cover page of this prospectus is subject to change as a result of market conditions and other factors. LEGAL MATTERS The validity of the common stock offered hereby will be passed upon for us by Brobeck, Phleger & Harrison LLP, Austin, Texas. Other legal matters in connection with this offering will be passed upon for the underwriters by Davis Polk & Wardwell, New York, New York.

REPORT OF INDEPENDENT AUDITORS The Board of Directors Silicon Laboratories Inc. We have audited the accompanying consolidated balance sheets of Silicon Laboratories Inc. as of January 2, 1999 and January 1, 2000, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended January 1, 2000. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Silicon Laboratories Inc. at January 2, 1999 and January 1, 2000, and the consolidated results of its operations and its cash flows for each of the three years in the period ended January 1, 2000, in conformity with accounting principles generally accepted in the United States.

Within the semiconductor industry, the Company is known as a "fabless" company meaning that the ICs are manufactured by third-party semiconductor companies. The Company was incorporated in 1996, and emerged from the development stage in fiscal 1998. 2. SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION As of January 1, 1997, the Company prepares financial statements on a 52-53 week year that ends on the Saturday closest to December 31. Fiscal year 1997 ended on January 3, 1998, fiscal year 1998 ended on January 2, 1999, and fiscal year 1999 ended on January 1, 2000. PRINCIPLES OF CONSOLIDATION AND FOREIGN CURRENCY TRANSLATION The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Silicon Laboratories UK Limited. All significant intercompany balances and accounts have been eliminated. The functional currency of the Company's subsidiary is the U.S. dollar, accordingly, all translation gains and losses resulting from transactions denominated in currencies other than U.S. dollars are included in net income. CASH AND CASH EQUIVALENTS Cash and cash equivalents consist of cash deposits and investments with a maturity of three months or less when purchased. SHORT-TERM INVESTMENTS Cash investments in highly liquid financial instruments with original maturities greater than three months that mature within one year are classified as short-term investments. The Company's short-term investments consist of U.S. Government backed securities, which are classified as held-to-maturity and reported at amortized cost. FAIR VALUE OF FINANCIAL INSTRUMENTS The Company's financial instruments consist principally of cash and cash equivalents, short-term investments, receivables, accounts payable, and borrowings. The Company believes all of the financial instruments' recorded values approximate current market values. F-7

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 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): JANUARY 2, JANUARY 1, 1999 2000 ---------- ---------- Work in progress........................................ $511 $1,902 Finished goods.......................................... 124 935 ---- ------ $635 $2,837 ==== ====== PROPERTY, EQUIPMENT, AND SOFTWARE Property, equipment, and software are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the useful lives of the assets (generally four to five years). Amortization of assets recorded under capital leases is computed using the straight-line method over the shorter of the asset's useful life or the term of the lease and such amortization is included with depreciation expense. See also Note 4. Leasehold improvements are depreciated over the contractual obligation of the lease period or their useful life, whichever is shorter. Property, equipment and software consist of the following (in thousands): JANUARY 2, JANUARY 1, 1999 2000 ---------- ---------- Equipment............................................... $3,221 $10,014 Computers and purchased software........................ 1,854 3,779 Furniture and fixtures.................................. 86 326 Leasehold improvements.................................. 209 1,155 ------ ------- 5,370 15,274 Accumulated depreciation and amortization............... (952) (2,924) ------ ------- $4,418 $12,350 ====== ======= USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates, and such differences could be material to the financial statements. RISKS AND UNCERTAINTIES Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, short-term investments and accounts receivable. The Company places its cash, cash equivalents and short-term investments primarily in market rate accounts and U.S. Treasury bills. The Company performs ongoing credit evaluations of its customers' financial condition and generally requires no collateral from its customers. The Company provides an allowance for doubtful F-8
SILICON LABORATORIES INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) accounts receivable based upon the expected collectibility of such receivables. The following table summarizes the changes in the allowance for doubtful accounts receivable (in thousands): Balance at January 1, 1997.................................. $ Additions charged to costs and expenses..................... -- Write-off of uncollectible accounts......................... -- ---- Balance at January 3, 1998.................................. $ -- Additions charged to costs and expenses..................... 56 Write-off of uncollectible accounts......................... -- ---- Balance at January 2, 1999.................................. $ 56 Additions charged to costs and expenses..................... 513 Write-off of uncollectible accounts......................... -- ---- Balance at January 1, 2000.................................. $569 All of the Company's products are currently manufactured by two companies in Taiwan. A manufacturing disruption experienced by either of the Company's manufacturing partners could impact the production of the Company's products for a substantial period of time, which could have a material adverse effect on the Company's business, financial condition and results of operations. The following is a detail of customers that accounted for greater than 10% of gross revenue in the respective fiscal years: YEAR ENDED ------------------------------------ JANUARY 3, JANUARY 2, JANUARY 1, 1998 1999 2000 ---------- ---------- ---------- Customer A.................................... --% 78% 62% Customer B.................................... -- -- 12 Customer C.................................... -- 20 10 INCOME TAXES The Company accounts for income taxes in accordance with Statement of Financial Accounting Standards (SFAS) No. 109, ACCOUNTING FOR INCOME TAXES. This statement requires the use of the liability method whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. REVENUE RECOGNITION Revenue from product sales direct to customers is recognized upon shipment. Certain of the Company's sales are made to distributors under agreements allowing certain rights of return and price protection on products unsold by distributors. Accordingly, the Company defers revenue and gross profit on such sales until the product is sold by the distributors. ADVERTISING Advertising costs are expensed as incurred. Advertising expenses were $4,269, $66,804 and $296,692 in the fiscal years ended January 3, 1998, January 2, 1999, and January 1, 2000, respectively. F-9
SILICON LABORATORIES INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) STOCK-BASED COMPENSATION Financial Accounting Standards Board's ("FASB") SFAS No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION, prescribes accounting and reporting standards for all stock-based compensation plans, including employee stock options. As allowed by SFAS No. 123, the Company has elected to continue to account for its employee stock-based compensation in accordance with Accounting Principles Board Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES. OTHER COMPREHENSIVE INCOME (LOSS) In June 1997, the FASB issued SFAS No. 130, REPORTING COMPREHENSIVE INCOME, which establishes standards for reporting and display of comprehensive income and its components in the financial statements. There were no differences between net income (loss) and comprehensive income (loss) during any of the periods presented. SEGMENT INFORMATION Effective April 1, 1998, the Company adopted SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION. The adoption of SFAS No. 131 did not have a significant effect on the disclosure of segment information as the Company continues to consider its business activities as a single segment. The Company has one operating segment with two product divisions (the Wireline and Wireless Divisions). The chief operating decision maker allocates resources and assesses performance of the business and other activities at the operating segment level. The Wireline Division accounted for substantially all of the sales in all periods. Approximately $0, $3,994, and $3,371,722 of the Company's revenues were from export sales for the fiscal years ended January 3, 1998, January 2, 1999, and January 1, 2000, respectively. The operations and assets of Silicon Laboratories UK Limited were immaterial in all periods presented. NET INCOME PER SHARE The Company computes net income (loss) per share in accordance with SFAS No. 128, EARNINGS PER SHARE. Under SFAS No. 128, basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares and dilutive common share equivalents outstanding. F-10
SILICON LABORATORIES INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands, except per share data): YEAR ENDED ------------------------------------ JANUARY 3, JANUARY 2, JANUARY 1, 1998 1999 2000 ---------- ---------- ---------- Net income (loss)........................................... $ (1,835) $ (3,397) $ 11,040 ======== ======== ======== Basic: Weighted-average shares of common stock outstanding....... 25,730 28,245 29,177 Weighted-average shares of common stock subject to repurchase..............................................

NEW ACCOUNTING PRONOUNCEMENTS In June 1998, the FASB issued SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES ("SFAS No. 133"). SFAS No. 133 is effective for fiscal years beginning after June 15, 2000. SFAS No. 133 requires that all derivative instruments be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income. The Company does not expect that the adoption of SFAS No. 133 will have a material impact on its financial statements because the Company does not believe it currently holds any derivative instruments. In December 1999, the Securities and Exchange Commission staff released Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements ("SAB No. 101"), which provides guidance on the F-11
SILICON LABORATORIES INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) recognition, presentation and disclosure of revenue in financial statements. The application of SAB No. 101 did not have a material impact on the financial statements of the Company. On March 31, 1999, the FASB issued an exposure draft entitled "Accounting for Certain Transactions Involving Stock Compensation," which is a proposed interpretation of APB Opinion No. 25. However, the exposure draft has not been finalized. Once finalized and issued, the current accounting practices for transactions involving stock compensation may need to change and such changes could affect the Company's future earnings. 3. SHORT-TERM INVESTMENTS The Company's short-term investments consist of U.S. Treasury bills with interest rates ranging from 4.72% to 5.10% which mature at varying dates through May 25, 2000 and are considered to be held-to-maturity. Securities classified as held-to-maturity, which consist of securities that management has both the ability and positive intent to hold to maturity, are carried at amortized cost which approximates fair value. 4. LONG-TERM OBLIGATIONS Long-term debt and leases consist of the following: JANUARY 2, JANUARY 1, 1999 2000 ---------- ---------- (IN THOUSANDS) Bank term loans due in monthly installments of $27,669 and $41,645 plus interest at bank prime (8.5% at January 1, 2000) through March 31, 2001 and January 31, 2002, respectively.............................................. $2,246 $1,456 Note payable, at 9.08%, payable in monthly installments of $24,810 through March 1, 2003 with a $200,600 interest payment due at maturity................................... -- 835 Note payable, at 9.77%, payable in monthly installments of $4,113 through June 1, 2003............................... -- 146 Note payable, at 9.91%, payable in monthly installments of $14,050 through September 1, 2003......................... -- 526 Note payable, at 10.22%, payable in monthly installments of $5,829 through December 1, 2003........................... -- 231 Note payable, at 6.71%, payable in monthly installments of $30,635 through February 28, 2003 with a $243,000 interest payment due at maturity................................... -- 1,046 Note payable, at 6.92%, payable in monthly installments of $19,340 through July 31, 2003 with a $152,900 interest payment due at maturity................................... -- 719 Note payable, at 7.13%, payable in monthly installments of $40,017 to $46,005 through April 30, 2004 with a $399,200 interest payment due at maturity.......................... -- 1,956 Note payable, at 7.5%, payable in monthly installments of $9,912 to $11,399 through April 30, 2004 with a $98,116 interest payment due at maturity.......................... -- 481 Capital lease obligations................................... 796 1,382 ------ ------ 3,042 8,778 Current portion.............................................

SILICON LABORATORIES INC. NOTES TO FINANCIAL STATEMENTS (CONTINUED) 4. LONG-TERM OBLIGATIONS (CONTINUED) The amounts outstanding under the above term loans are in connection with a $2.5 million loan facility (see Note 5 for discussion of warrants issued). In addition, the Company obtained new loan facilities in December 1999 totaling $4 million, of which no amounts were outstanding as of January 1, 2000. These additional facilities also bear interest at bank prime (8.5% as of January 1, 2000). The collateral for these loans includes a blanket lien on all otherwise unsecured tangible property, inventory, and accounts receivable. These loans and the letter of credit (See Note 6) are cross-collateralized and cross-defaulted. There are covenants related to net worth and liquidity associated with these financing lines, with which the company is in compliance as of January 1, 2000. The Company has a revolving line of credit agreement (the Agreement) with a bank that is collateralized by certain assets of the company. Under the provisions of the Agreement, the line of credit allows for borrowings of up to $3 million or 80% of eligible accounts receivable at bank prime (8.5% as of January 1, 2000). There were no amounts outstanding under this facility as of January 2, 1999 and January 1, 2000. The notes payable and capital lease obligations are borrowings with three institutional financing providers for equipment financing. The indebtedness is secured by a security interest in the underlying equipment. Periodically, the Company will purchase or make advance deposits toward the purchase of machinery and equipment; and within one to three months enter into leasing arrangements to finance these assets. These leasing arrangements result in the reimbursement of the amounts initially paid by the Company and do not result in any gains or losses. Such reimbursements have been reflected in the statement of cash flows as proceeds from equipment lease financings. The Company has financed the acquisition of certain computers and other equipment under capital lease transactions which are accounted for as financings and mature through fiscal year 2003. As of January 2, 1999 and January 1, 2000, equipment under capital lease included in property, equipment and software was $796,000 and $1,382,000, respectively. At January 1, 2000, contractual maturities of debt and future minimum annual payments due under capital lease obligations are as follows (in thousands): CAPITAL FISCAL YEAR DEBT LEASES TOTAL - - ----------- -------- -------- -------- 2000.............................................. $ 2,188 $ 646 $ 2,834 2001.............................................. 2,117 637 2,754 2002.............................................. 1,740 343 2,083 2003.............................................. 1,125 12 1,137 2004.............................................. 226 -- 226 ------- ------ ------- 7,396 1,638 9,034 Less amount representing interest................. -- (256) (256) ------- ------ ------- 7,396 1,382 8,778 Less current portion..............................

Each share is convertible at the option of the stockholder into two shares of common stock, subject to certain anti-dilution adjustments. The Convertible Preferred Stockholders are entitled to the number of votes equal to the number of shares of common stock into which each share of Convertible Preferred Stock could be converted on the record date. Conversion is automatic upon the closing of an underwritten public offering of the Company's common stock meeting certain criteria; or if less than one-third of the Convertible Preferred Stock remain outstanding for that series. Additional contractual obligations by and between the holders of Convertible Preferred Stockholders and the holders of common stock exist with regards to registration rights, indemnification, rights of first offer, rights of first refusal and voting of shares. The stockholders of Series A and Series B Convertible Preferred Stock are entitled to cumulative dividends of $0.0589286 and $0.2856 per share, respectively, beginning January 1, 2002 and continuing thereafter whether or not earned or declared. In the event of conversion to common stock, the preferred stockholders shall receive, when applicable after January 1, 2002, consideration at conversion for all accrued and unpaid dividends. In the event of a liquidation or winding up of the Company, stockholders of Series A and Series B Convertible Preferred Stock shall have a liquidation preference of $0.982144225 and $4.76 per share, respectively, plus declared and unpaid dividends, over holders of common stock.

A majority of the holders of Series A and Series B Convertible Preferred Stock, voting as one group, may elect to require the Company, for an amount per share equal to the liquidation price, to redeem on or after the dates specified below up to a cumulative total of that percentage of the shares on Series A and B Convertible Preferred Stock, net of any shares previously redeemed: CUMULATIVE PERCENTAGE OF SHARES REDEMPTION DATE WHICH MAY BE REDEEMED - - --------------- ------------------------------- March 21, 2005.................................... 33 1/3% March 21, 2006.................................... 66 2/3% March 21, 2007.................................... 100 % WARRANTS A warrant to purchase 45,818 shares of Series A Convertible Preferred Stock at $0.982144225 per share was outstanding at January 1, 2000. The warrant is exercisable at any time before November 20, 2002. The warrant was issued in 1997 to a commercial bank in connection with the extension of debt financing (see Note 4). A warrant to purchase 21,008 shares of Series B Convertible Preferred Stock at $4.76 per share was outstanding at January 1, 2000. The warrant is exercisable at any time before September 22, 2008, or the earlier consummation of an initial public offering. The warrant was issued in 1998 to an equipment lessor in connection with the extension of lease and debt financing (see Notes 4 and 6). A warrant to purchase 4,765 shares of Series B Convertible Preferred Stock at $4.76 per share was outstanding at January 1, 2000. The warrant is exercisable at any time before September 4, 2003. The warrant was issued in 1998 to a commercial bank in connection with the issuance of a letter of credit facility for leasehold improvements (see Note 6). No amount was allocated to the value of the above warrants as such amounts were not significant. COMMON STOCK The Company had 30,015,944 shares of common stock outstanding as of January 1, 2000. Of these shares, 11,910,298 shares were unvested and are subject to rights of repurchase that lapse according to a time based vesting schedule. Of the shares unvested and subject to rights of repurchase, 7,467,000 shares vest upon an initial public offering of common stock that meet certain criteria. F-15
SILICON LABORATORIES INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 5. STOCKHOLDERS' EQUITY (CONTINUED) Common stock reserved at January 1, 2000 consists of the following: For exercise of Convertible Preferred Stock................. 13,842,174 For exercise of Convertible Preferred Stock Warrants........ 143,182 For issuance under the Company's 1997 Stock Option/Stock Issuance Plan............................................. 3,389,498 ---------- 17,374,854 ========== STOCK SPLIT On November 3, 1999, the Company effected a two-for-one stock split through a stock dividend of common stock. All references to common stock share and per share amounts including options to purchase common stock have been retroactively restated to reflect the stock split as if such split had taken place at the inception of the Company. Also, the conversion ratio of the redeemable convertible preferred stock has been adjusted from one-for-one to one-for-two. STOCK OPTION/STOCK ISSUANCE PLAN The Company has a 1997 Stock Option/Stock Issuance Plan (the "Plan") whereby employees, members of the Board of Directors and independent advisors may be granted options to purchase shares of the Company's common stock or may be issued shares of the Company's common stock ("direct issuance shares") as a direct purchase or as a bonus for services rendered to the Company. These direct issuances of common stock are usually subject to rights of repurchase. At January 1, 2000, 8,561,808 shares were authorized for issuance under the Plan. The term of each option is no more than ten years from the date of grant. The options generally vest over a five to eight year period, and are immediately exercisable subject to a repurchase agreement which generally lapses in accordance with the vesting schedule. The direct issuance shares are also subject to repurchase rights which generally lapse over a five to eight year period. The repurchase rights provide that upon certain defined events, the Company can repurchase unvested shares at the price paid per share and gives the Company the right of first refusal for any proposed disposition of shares issued under the Plan. The Company recorded deferred stock compensation expense of $414,000 and $15,899,000 in connection with stock options granted for 355,500 shares and 2,464,200 shares of common stock during fiscal 1998 and 1999, respectively. These amounts represent the difference between the exercise price of the stock option and the subsequently deemed fair value of the Company's common stock. The deferred stock compensation is amortized over the vesting periods of the applicable options, resulting in amortization of $8,000 and $975,000 for the year ended January 2, 1999 and the year ended January 1, 2000, respectively. During fiscal 1997, 1998 and 1999, the Company made full recourse loans to employees of $77,000, $147,500 and $1,267,500, respectively, in connection with the employees' purchase of shares through exercises of options. These full recourse notes are secured by the shares of stock, are interest bearing at rates ranging from 4.8% to 6.7%, have terms of five years, and must be repaid upon the sale of the underlying shares of stock.

The Company's pro forma information is as follows (in thousands, except per share data): YEAR ENDED ------------------------------------ JANUARY 3, JANUARY 2, JANUARY 1, 1998 1999 2000 ---------- ---------- ---------- Pro forma net income (loss)................... $(1,835) $(3,400) $11,014 Pro forma basic net income (loss) per share... (1.04) (.37) .73 Pro forma diluted net income (loss) per share....................................... (1.04) (.37) .25 Option valuation models incorporate highly subjective assumptions. Because changes in the subjective assumptions can materially affect the fair value estimate, the existing models do not necessarily provide a reliable single measure of the fair value of the Company's employee stock options. Because the determination of fair value of all employee stock options granted after such time as the Company becomes a public entity will include an expected volatility factor and because, for pro forma disclosure purposes, the estimated fair value of the Company's employee stock options is treated as if amortized to expense over the options' vesting period, the effects of applying SFAS No 123 for pro forma disclosures are not necessarily indicative of future amounts. 6. COMMITMENTS AND CONTINGENCIES The Company's main executive, administrative and technical offices occupy approximately 37,800 square feet in Austin, Texas under a lease that expires in April 2006, with one five year renewal option. Monthly rental payments increase by $1,575 per month in April 2002 and again in April 2004. The Company has an additional lease commitment for approximately 34,000 square feet in Austin, Texas for supplemental office space under a 76 month lease with one five year renewal option. The Company expects occupancy to commence in February 2000. Monthly rental payment increase from $22,301 to $48,919 per month at various intervals throughout the term of the lease. To provide security for the landlord on the main offices, the Company provided a long-term cash deposit of $113,400 and a letter of credit for $453,600. At January 1, 2000, there were no outstanding amounts under the letter of credit. Based on certain financial performance criteria, the letter of credit requirements could be reduced to $255,600. (see also Note 4). To provide security to the landlord on the additional lease commitment for February 2000 occupancy, the Company provided a long-term cash deposit of $64,800 and a letter of credit for $500,000. At January 1, 2000, no amounts were outstanding under the letter of credit. The letter of credit requirements could be reduced in even annual installments based upon satisfactory performance under the lease or eliminated entirely based on certain financial performance criteria. This letter of credit is provided under the revolving line of credit from a commercial bank (see Note 4). F-18

COMMITMENTS AND CONTINGENCIES (CONTINUED) The minimum annual future rentals under the terms of these leases at January 1, 2000 are as follows (in thousands): FISCAL YEAR - - ----------- 2000........................................................ $ 832 2001........................................................ 988 2002........................................................ 1,033 2003........................................................ 1,042 2004........................................................ 1,071 Thereafter.................................................. 1,487 ------ Total minimum lease payments................................ $6,453 ====== Rent expense for operating leases was approximately $45,740, $144,784 and $373,983 for the years ended January 3, 1998, January 2, 1999, and January 1, 2000, respectively. The Company is involved in various 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 and results of operations. 7. INCOME TAXES Deferred income taxes reflect the net tax effects of temporary differences between the carrying values of assets and liabilities for financial reporting purposes and the values used for income tax purposes. Significant components of the Company's deferred taxes as of January 2, 1999 and January 1, 2000 are as follows: JANUARY 2, JANUARY 1, 1999 2000 ---------- ---------- Deferred tax liabilities: Depreciable assets.................................... $ (209) $ -- Deferred tax assets: Depreciable assets.................................... -- $ 28 Reserves and allowances............................... 113 568 Net operating loss and tax credit carryforwards....... 2,231 -- Deferred revenue...................................... -- 381 Deferred compensation................................. -- 46 Accrued liabilities & other........................... 29 55 ------- ------ 2,164 1,078 ------- ------ Net deferred tax assets before valuation allowance.... 2,164 1,078 ------- ------ Valuation allowance for net deferred tax asset........ (2,164) -- ------- ------ Net deferred taxes.................................... $ -- $1,078 ======= ====== F-19
SILICON LABORATORIES INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 7. INCOME TAXES (CONTINUED) The Company established a valuation allowance of $2,164,000 for the year ended January 2, 1999, due to uncertainties regarding the realization of net deferred tax assets because of the Company's lack of earnings history. The valuation allowance decreased by $2,164,000 for the year ended January 1, 2000, as a result of the increased earnings of the Company during the current year. Significant components of the provision (benefit) for income taxes attributable to continuing operations are as follows: JANUARY 3, JANUARY 2, JANUARY 1, 1998 1999 2000 ---------- ---------- ---------- Current: Federal..................................... $-- $-- $ 4,009 State....................................... -- -- 393 --- --- ------- Total Current............................... -- -- 4,402 Deferred: Federal..................................... -- -- (993) State....................................... -- -- (85) --- --- ------- Total Deferred.............................. -- -- (1,078) --- --- ------- $ 0 $ 0 $ 3,324 === === ======= The Company's provision (benefit) for income taxes differs from the expected tax expense (benefit) amount computed by applying the statutory federal income tax rate to income (loss) before income taxes as a result of the following: JANUARY 3, 1998 JANUARY 2, 1999 JANUARY 1, 2000 --------------- --------------- --------------- Pre-tax book income (loss) at statutory rate....... (34.0)% (34.0)% 35.0% State taxes, net of federal benefit................

Such compensation results from increases in the fair market value of the Company's common stock subsequent to the date of grant of the exercised stock options and, in accordance with APB 25, such compensation is not recognized as an expense for financial accounting purposes; however, the related tax benefits are recorded as an addition to Additional Paid-in-Capital. 8. EMPLOYEE BENEFIT PLAN During fiscal 1997, the Company established the Silicon Laboratories Inc. 401(k) Plan ("the 401(k) Plan") for the benefit of substantially all employees. The Company is the administrator of the 401(k) Plan. F-20
SILICON LABORATORIES INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) 8. EMPLOYEE BENEFIT PLAN (CONTINUED) To be eligible for the 401(k) Plan, employees must have reached the age of 21. Participants may elect to contribute up to 15% of their compensation to the 401(k) Plan. The Company may make discretionary matching contributions of up to 10% of a participant's compensation as well as discretionary profit-sharing contributions to the 401(k) Plan. The Company's contributions to the 401(k) Plan vest over four years at a rate of 25% per year. The Company has not contributed to the Plan to date. 9. SUBSEQUENT EVENTS On January 5, 2000 the Company's Board of Directors authorized management to file a registration statement with the Securities and Exchange Commission to permit the Company to sell shares of its common stock to the public. In connection with this authorization, the Board approved increasing the authorized shares of common stock to 250,000,000. On January 5, 2000 the Company's Board of Directors approved The 2000 Stock Incentive Plan ("Plan"). The Plan has been approved by the Company's stockholders. The Company has reserved 5,389,498 shares of common stock for issuance under this plan (consisting of the shares available under the predecessor plan on the effective date plus an additional 2,000,000 shares). Also on January 5, 2000 the Board adopted the Employee Stock Purchase Plan. The plan has been approved by the Company's stockholders and will become effective upon the execution of the underwriting agreement for the Company's currently proposed initial public offering. F-21

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of the Delaware General Corporation Law (the "DGCL") provides, in effect, that any person made a party to any action by reason of the fact that he is or was a director, officer, employee or agent of Silicon Laboratories may and, in some cases, must be indemnified by Silicon Laboratories against, in the case of a non-derivative action, judgments, fines, amounts paid in settlement and reasonable expenses (including attorneys' fees) incurred by him as a result of such action, and in the case of a derivative action, against expenses (including attorneys' fees), if in either type of action he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of Silicon Laboratories. This indemnification does not apply, in a derivative action, to matters as to which it is adjudged that the director, officer, employee or agent is liable to Silicon Laboratories, unless upon court order it is determined that, despite such adjudication of liability, but in view of all the circumstances of the case, he is fairly and reasonably entitled to indemnity for expenses, and, in a non-derivative action, to any criminal proceeding in which such person had no reasonable cause to believe his conduct was unlawful. Our certificate of incorporation, provides that no director shall be liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by the DGCL. Our bylaws require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law. We have entered into indemnification agreements with all of our directors and executive officers and have purchased directors' and officers' liability insurance. Reference is made to the underwriting agreement to be filed as Exhibit 1.1 hereto, pursuant to which the underwriters have agreed to indemnify our officers and directors against certain liabilities under the Securities Act. Silicon Laboratories has entered into Indemnification Agreements with each director and executive officer, a form of which is filed as Exhibit 10.1 to this Registration Statement. Pursuant to such agreements, we will be obligated, to the extent permitted by applicable law, to indemnify such directors and executive officers against all expenses, judgments, fines and penalties incurred in connection with the defense or settlement of any actions brought against them by reason of the fact that they were directors or executive II-1
officers of Silicon Laboratories or assumed responsibilities at the direction of Silicon Laboratories. Silicon Laboratories also intends to purchase directors and officers liability insurance in order to limit its exposure to liability for indemnification of directors and executive officers. ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES Between August 1996 and January 1, 2000, we issued unregistered securities to a limited number of people as described below. 1. In August and December 1996 and May 1997, we issued an aggregate of 24,843,634 shares to Navdeep S. Sooch, David R. Welland, Jeffrey W. Scott and John W. McGovern at purchase prices ranging from $0.00005 to $0.0005 per share in compliance with Rule 506. 2.

The following stockholders purchased our Series A Preferred Stock: Austin Ventures IV-A, L.P.; Austin Ventures IV-B, L.P.; Austin Ventures V, L.P.; Silverton Partners; Donald Brooks; Dietrich R. Erdmann; and H. Berry Cash. Although the number of shares of Series A preferred stock outstanding was not affected by the 2-for-1 split of our common stock, as a result of this stock split, each share of Series A preferred stock automatically adjusted and became convertible into two shares of our common stock. These shares were issued to accredited investors in compliance with Rule 506. 3. In June 1998, Silicon Laboratories issued shares of Series B Preferred Stock for $4.76 per share, for an aggregate purchase price of $7,500,037.

Brooks; Dietrich R. Erdmann; Berry and Dianne Cash Grandchildren's Trust; Charles H. Cash; H. Berry Cash; KLM Capital Partners Fund; L.J. Sevin; and Jonathan D. Ivester. Although the number of shares of Series B preferred stock outstanding was not affected by the 2-for-1 split of our common stock, as a result of this stock split, each share of Series B preferred stock automatically adjusted and became convertible into two shares of our common stock. These shares were issued to accredited investors in compliance with Rule 506. 4. Through January 1, 2000, Silicon Laboratories has issued 5,172,310 shares of its common stock to directors, employees and consultants upon the exercise of options granted or directly issued under its 1997 Stock Option/Stock Issuance Plan at a weighted average purchase price of $.45 per share. These shares were issued to employees and consultants in compliance with Rule 701. II-2

UNDERTAKINGS. The undersigned hereby undertakes to provide to the underwriter at the closing specified in the underwriting agreements, certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the DGCL, our Certificate of Incorporation or our Bylaws, the underwriting agreement or otherwise, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by us of expenses incurred or paid by one of our directors, officers, or II-4
controlling persons in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, we will, unless in the opinion of our counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. We hereby undertake that: 1. For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by us pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective. 2. For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and this offering of such securities at that time shall be deemed to be the initial BONA FIDE offering thereof.

Subject to compliance with applicable protective voting rights which may be granted to the Preferred Stock or series thereof in Certificates of Designation or the Corporation's Certificate of Incorporation, as amended and as hereafter may be amended ("Protective Provisions"), but notwithstanding any other rights of the Preferred Stock or any series thereof, the rights, privileges, preferences and restrictions of any such additional series may be subordinated to, pari passu with (including, without limitation, inclusion in provisions with respect to liquidation and 1

The rights, preferences, privileges and restrictions granted to and imposed on the Series A Preferred Stock and the Series B Preferred Stock are as set forth below in this Article IV(B). 1. DIVIDEND PROVISIONS. (a) Subject to the rights of Preferred Stock which may hereafter come into existence, prior to January 1, 2002, the holders of shares of Series A Preferred Stock and Series B Preferred Stock shall be entitled to receive dividends, out of any assets legally available therefor, when, as and if declared by the Board of Directors. (b) Subject to the rights of Preferred Stock which may hereafter come into existence, beginning January 1, 2002 and continuing thereafter, the holders of shares of Series A Preferred Stock shall be entitled to receive dividends, out of any assets legally available therefor, at the rate of $0.0589286 (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to such series after March 21, 1997 (the "Initial Series A Issue Date")) per share of Series A Preferred Stock per annum, payable when, as and if declared by the Board of Directors, and such dividends shall be cumulative and shall accrue on each share from January 1, 2002, from day to day thereafter, whether or not earned or declared.

Any accumulation of dividends on the Series A Preferred Stock or Series B Preferred Stock shall not bear interest. Cumulative dividends with respect to shares of Series A Preferred Stock or Series B Preferred Stock which are accrued, payable and/or in arrears shall, upon conversion of such shares to Common Stock, at the option of the Corporation either: (i) subject to the rights of series of Preferred Stock which may from time to time come into existence, be paid in cash to the extent assets are legally available therefor or (ii) be convertible into such additional shares of Common Stock determined by dividing the amount of such dividends by the fair market value of the Common Stock (as determined by the Corporation's Board of Directors) on the date of such conversion (with any fractional share rounded to the nearest whole share, with 0.5 being rounded upward). (c) Each share of Series A Preferred Stock and Series B Preferred Stock shall rank equally in all respects with respect to dividends; provided, however, that the 2
Corporation shall not declare or pay dividends which are insufficient to pay all accrued dividends on each series of Preferred Stock outstanding unless such dividends are declared and paid to each series of Preferred Stock pro rata based on the accrued dividends with respect to such series as a percentage of accrued dividends for all series of Preferred Stock. (d) Until such time as neither shares of Series A Preferred Stock nor Series B Preferred Stock are outstanding, no dividend whatsoever shall be paid or declared, and no distribution shall be made, on Common Stock (other than a dividend payable solely in Common Stock or other securities and rights convertible into or entitling the holder thereof to receive, directly or indirectly, additional shares of Common Stock). (e) Any dividend or distribution which is declared by the Corporation and payable with assets of the Corporation, other than cash, shall be deemed to have such value as determined by the Board of Directors. 2. LIQUIDATION PREFERENCE. (a) In the event of any liquidation, dissolution or winding up of the Corporation, either voluntary or involuntary, subject to the rights of series of Preferred Stock that may from time to time come into existence, (A) each holder of Series A Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Corporation to the holders of Common Stock by reason of their ownership thereof, an amount per share (the "Series A Liquidation Amount") equal to the sum of: (i) $0.982144225 (the "Original Series A Issue Price") (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to such series after the Initial Series A Issue Date) for each outstanding share of Series A Preferred Stock held by such holder and (ii) an amount equal to all accrued but unpaid dividends on the shares of Series A Preferred Stock held by such holder and (B) each holder of Series B Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Corporation to the holders of Common Stock by reason of their ownership thereof, an amount per share (the "Series B Liquidation Amount") equal to the sum of: (i) $4.76 (the "Original Series B Issue Price") (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to such series after the Initial Series B Issue Date) for each outstanding share of Series B Preferred Stock held by such holder and (ii) an amount equal to all accrued but unpaid dividends on the shares of Series B Preferred Stock held by such holder. If upon the occurrence of such event, the assets and funds thus distributed among the holders of the Series A Preferred Stock and Series B Preferred Stock shall be insufficient to permit the payment to such holders of the full aforesaid preferential amounts, then, subject to the rights of series of Preferred Stock that may from time to time come into existence, the entire assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series A Preferred Stock and Series B Preferred Stock in proportion to the relative liquidation preference of the shares of Series A Preferred Stock and Series B Preferred Stock then held by them. (b) After the distribution described in Subsection 2(a) above and any other distribution that may be required with respect to series of Preferred Stock that may from time to time come into existence, the remaining assets of the Corporation available for distribution to stockholders shall be distributed among the holders of the Series A Preferred 3
Stock, Series B Preferred Stock and Common Stock pro rata based on the number of shares of Common Stock held by each (determined on an as-converted basis with respect to outstanding shares of Series A Preferred Stock and Series B Preferred Stock); provided that the amount which the holders of Series A Preferred Stock and Series B Preferred Stock shall be entitled to receive pursuant to Subsection 2(a) and this Subsection 2(b), if any, in the aggregate shall not exceed (i) $2.946432675 (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to such series after the Initial Series A Issue Date) for each outstanding share of Series A Preferred Stock held by such holder and (ii) $14.28 (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to such series after the Initial Series B Issue Date) for each outstanding share of Series B Preferred Stock held by such holder. (c) After the distributions described in Subsections (a) and (b) above have been paid, subject to the rights of series of Preferred Stock that may from time to time come into existence, the remaining assets of the Corporation available for distribution to stockholders shall be distributed among the holders of Common Stock pro rata based on the number of shares of Common Stock held by each. (d) (i) For purposes of this Section 2, upon the affirmative vote of the holders of at least sixty-seven percent (67%) of the shares of Series A Preferred Stock and Series B Preferred Stock then outstanding, voting together as a single class, a liquidation, dissolution or winding up of the Corporation shall be deemed to be occasioned by, or to include: (A) the acquisition of the Corporation by another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation) or (B) a sale of all or substantially all of the assets of the Corporation; unless the Corporation's stockholders of record as constituted immediately prior to such acquisition or sale will, immediately after such acquisition or sale (by virtue of securities issued as consideration for the Corporation's acquisition or sale or otherwise) hold at least fifty percent (50%) of the voting power of the surviving or acquiring entity; provided, however, that shares of the surviving entity held by holders of the capital stock of the Corporation acquired by means other than the exchange or conversion of the capital stock of the Corporation for shares of the surviving entity shall not be used in determining if the stockholders of the Corporation own more than fifty percent (50%) of the voting power of the surviving or acquiring entity, but shall be used for determining the total outstanding voting power of such entity. (ii) In any of such events, if the consideration received by the Corporation is other than cash, its value will be deemed its fair market value. Any securities to be delivered to the holders of the Series A Preferred Stock, Series B Preferred Stock or Common Stock, as the case may be, shall be valued as follows: (A) If traded on a securities exchange or through the Nasdaq National Market, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the thirty-day period ending three (3) days prior to the closing; (B) If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) over the thirty-day period ending three (3) days prior to the closing; and 4
(C) If there is no active public market, the value shall be the fair market value thereof, as mutually determined by the Corporation and the holders of at least a majority of the then outstanding shares of Series A Preferred Stock and Series B Preferred Stock, voting together as a single class. (iii) In the event the requirements of this Subsection 2(d) are not complied with, the Corporation shall forthwith either: (A) cause such closing to be postponed until such time as the requirements of this Section 2 have been complied with; or (B) cancel such transaction, in which event the respective rights, preferences and privileges of the holders of the Series A Preferred Stock and Series B Preferred Stock shall revert to and be the same as such rights, preferences and privileges existing immediately prior to the date of the first notice referred to in Subsection 2(d)(iv) below. (iv) The Corporation shall give each holder of record of Series A Preferred Stock and Series B Preferred Stock written notice of such impending transaction not later than twenty (20) days prior to the stockholders' meeting called to approve such transaction, or twenty (20) days prior to the closing of such transaction, whichever is earlier, and shall also notify such holders in writing of the final approval of such transaction. The first of such notices shall describe the material terms and conditions of the impending transaction and the provisions of this Section 2, and the Corporation shall thereafter give such holders prompt notice of any material changes. The transaction shall in no event take place sooner than twenty (20) days after the Corporation has given the first notice provided for herein or sooner than ten (10) days after the Corporation has given notice of any material changes provided for herein; provided, however, that such periods may be shortened upon the Corporation's receipt of written consent of the holders of at least a majority of the Series A Preferred Stock and Series B Preferred Stock (voting together as a single class) entitled to such notice rights or similar notice rights. 3. REDEMPTION. (a) Subject to the rights of series of Preferred Stock that may from time to time come into existence, the holders of not less than a majority of the then outstanding Series A Preferred Stock and Series B Preferred Stock, voting together as a single class, may elect to require the Corporation to redeem (a "Redemption Request") on or after the dates specified below up to a cumulative total of that percentage of the shares of Series A Preferred Stock and Series B Preferred Stock held by each such requesting holder as set forth below opposite such Redemption Date, less the number of shares of Series A Preferred Stock and Series B Preferred Stock redeemed by the Company pursuant to this Subsection 3(a) from such holder (or its predecessors) prior to the date of such election: 5
Cumulative Percentage of Shares Redemption Which May be Date Redeemed --------------- ------------- March 21, 2005 33 1/3% March 21, 2006 66 2/3% March 21, 2007 100%. In each such event, the Corporation shall, to the extent it may lawfully do so, redeem the shares specified in such Redemption Request within thirty (30) days following the later of the date of receipt of such Redemption Notice or the applicable Redemption Date, upon surrender by the requesting holders of the certificates representing such shares by paying a sum per share of Series A Preferred Stock equal to the Series A Liquidation Amount and a sum per share of Series B Preferred Stock equal to the Series B Liquidation Amount (such sums being the respective "Redemption Price" for the Series A Preferred Stock and Series B Preferred Stock). Any redemption effected pursuant to this Subsection (3)(a) shall be made on a pro rata basis among the requesting holders of the Series A Preferred Stock and Series B Preferred Stock in proportion to the number of shares of Series A Preferred Stock and Series B Preferred Stock then held by such holders. If any date fixed for redemption of shares pursuant to this Subsection 3(a) is a Saturday, Sunday or legal holiday, then such redemption shall occur on the first business day thereafter. (b) As used herein and in Subsections (3)(a) above and (3)(c) and (3)(d) below, the term "Redemption Date" shall refer to each date on which shares of Series A Preferred Stock or Series B Preferred Stock are requested to be redeemed as provided in Subsection 3(a). Subject to the rights of series of Preferred Stock that may from time to time come into existence, at least fifteen (15) but no more than thirty (30) days prior to each Redemption Date, written notice shall be mailed, first class postage prepaid, to each holder of record (at the close of business on the business day next preceding the day on which notice is given) of the Series A Preferred Stock and Series B Preferred Stock requested to be redeemed, at the address last shown on the records of the Corporation for such holder, notifying such holder of the redemption to be effected, specifying the number of shares to be redeemed from such holder, the Redemption Date, the applicable Redemption Price, the place at which payment may be obtained and calling upon such holder to surrender to the Corporation, in the manner and at the place designated, his, her or its certificate or certificates representing the shares of Series A Preferred Stock and Series B Preferred Stock to be redeemed (the "Redemption Notice"). Except as provided in Subsection (3)(c), on or after the Redemption Date, each holder of Series A Preferred Stock and Series B Preferred Stock to be redeemed shall surrender to the Corporation the certificate or certificates representing such shares, in the manner and at the place designated in the Redemption Notice, and thereupon the applicable Redemption Price of such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof and each surrendered certificate shall be canceled. In the event 6
less than all the shares represented by any such certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. (c) From and after each Redemption Date, unless there shall have been a default in payment of the applicable Redemption Price, all rights of the holders of shares of Series A Preferred Stock and Series B Preferred Stock designated for redemption in the Redemption Notice as holders of such shares of Series A Preferred Stock and Series B Preferred Stock (except the right to receive the applicable Redemption Price without interest upon surrender of their certificate or certificates) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purpose whatsoever. Subject to the rights of Preferred Stock that may from time to time come into existence, if the funds of the Corporation legally available for redemption of shares of Series A Preferred Stock and Series B Preferred Stock on any Redemption Date are insufficient to redeem the total number of shares of Series A Preferred Stock and Series B Preferred Stock to be redeemed on such date, those funds which are legally available will be used to redeem the maximum possible number of such shares ratably among the holders of such shares to be redeemed on the basis of the relative Redemption Prices of the shares of Series A Preferred Stock and Series B Preferred Stock to be redeemed. The shares of Series A Preferred Stock and Series B Preferred Stock not redeemed shall remain outstanding and entitled to all the rights and preferences provided herein. Subject to the rights of Preferred Stock that may from time to time come into existence, at any time thereafter when additional funds of the Corporation are legally available for the redemption of shares of Series A Preferred Stock and Series B Preferred Stock, such funds will immediately be used to redeem the balance of the shares which the Corporation has become obliged to redeem on any Redemption Date but which it has not redeemed. (d) On or prior to each Redemption Date, the Corporation may deposit the applicable Redemption Price of all shares of Series A Preferred Stock and Series B Preferred Stock designated for redemption in the Redemption Notice, and not yet redeemed or converted, with a bank or trust corporation having aggregate capital and surplus in excess of $100,000,000 as a trust fund for the benefit of the respective holders of the shares designated for redemption and not yet redeemed, with irrevocable instructions and authority to the bank or trust corporation to publish the notice of redemption thereof and pay the applicable Redemption Price for such shares to their respective holders on or after the Redemption Date, upon receipt of notification from the Corporation that such holder has surrendered his, her or its share certificate to the Corporation pursuant to Subsection (3)(b) above. As of the date of such deposit (even if prior to the Redemption Date), the deposit shall constitute full payment of the shares to their holders. From and after the date of such deposit the shares so called for redemption shall be redeemed and shall be deemed to be no longer outstanding, and the holders thereof shall cease to be stockholders with respect to such shares and shall have no rights with respect thereto, except the rights to receive from the bank or trust corporation payment of the applicable Redemption Price of the shares, without interest, upon surrender of their certificates therefor and the right to convert such shares as provided in Article IV(B)(4) below. Such instructions shall also provide that any monies deposited by the Corporation pursuant to this Subsection (3)(d) for the redemption of shares thereafter converted into shares of Common Stock pursuant to Article IV(B)(4) below prior to the Redemption Date shall be returned to the Corporation forthwith upon such conversion. The balance of any monies deposited by the Corporation pursuant to this 7
Subsection (3)(d) remaining unclaimed at the expiration of two (2) years followingthe final Redemption Date shall thereafter be returned to the Corporation upon its request expressed in a resolution of its Board of Directors. 4. CONVERSION. The holders of the Series A Preferred Stock and Series B Preferred Stock shall have conversion rights as follows (the "Conversion Rights"): (a) RIGHT TO CONVERT. Each share of Series A Preferred Stock and Series B Preferred Stock shall be convertible, at the option of the holder thereof, at any time after the date of issuance of such share, at the office of the Corporation or any transfer agent for such stock, into such number of fully paid and nonassessable shares of Common Stock as is determined, (i) with respect to each share of Series A Preferred Stock, by dividing the Original Series A Issue Price plus any accrued but unpaid dividends by the "Series A Conversion Price" in effect on the date the certificate therefor is surrendered for conversion and (ii) with respect to each share of Series B Preferred Stock, by dividing the Original Series B Issue Price plus any accrued but unpaid dividends by the "Series B Conversion Price" in effect on the date the certificate therefor is surrendered for conversion. The initial Series A Conversion Price shall be equal to the Original Series A Issue Price and the initial Series B Conversion Price shall be equal to the Original Series B Issue Price; provided, however, that such Series A Conversion Price and Series B Conversion Price shall be subject to adjustment as set forth in Subsections 4(d), (e) and (f) below. (b) AUTOMATIC CONVERSION. Each share of Series A Preferred Stock shall automatically be converted into shares of Common Stock at the Series A Conversion Price at the time in effect immediately upon the earlier of: (i) except as provided below in Subsection 4(c), the sale of Common Stock in a firm commitment underwritten public offering pursuant to a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), the public offering price per share of which is not less than $9.52 (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to the Common Stock after the Initial Series A Issue Date) and with gross proceeds to the Corporation and selling stockholders therein of at least $10,000,000 in the aggregate (a "Qualified Public Offering") or (ii) the date that, through the conversion or redemption of the Series A Preferred Stock, fewer than 1,781,816 shares (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to such series after the Initial Series A Issue Date) of the Series A Preferred Stock remain outstanding. Each share of Series B Preferred Stock shall automatically be converted into shares of Common Stock at the Series B Conversion Price at the time in effect immediately upon the earlier of: (i) except as provided below in Subsection 4(c), the sale of Common Stock in a firm commitment underwritten public offering pursuant to a registration statement under the Securities Act the public offering price per share of which is not less than $9.52 (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to the Common Stock after the Initial Series B Issue Date) and with gross proceeds to the Corporation and selling stockholders therein of at least $10,000,000 in the aggregate or (ii) the date that, through the conversion or redemption of the Series B Preferred Stock, fewer than 525,213 shares (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like with respect to such series after the Initial Series B Issue Date) of Series B Preferred Stock remain outstanding. 8
(c) MECHANICS OF CONVERSION. Before any holder of Series A Preferred Stock or Series B Preferred Stock shall be entitled to convert the same into shares of Common Stock, such holder shall surrender the certificate or certificates therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the Series A Preferred Stock or Series B Preferred Stock, as the case may be, and shall give written notice to the Corporation at its principal corporate office, of the election to convert the same and shall state therein the name or names in which the certificate or certificates for shares of Common Stock are to be issued. The Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Series A Preferred Stock or Series B Preferred Stock, as the case may be, or to the nominee or nominees of such holder, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Series A Preferred Stock or Series B Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock as of such date. If the conversion is in connection with an underwritten offering of securities registered pursuant to the Securities Act, the conversion shall be conditioned upon the closing with the underwriters of the sale of securities pursuant to such offering, in which event the person(s) entitled to receive the Common Stock upon conversion of such Preferred Stock shall not be deemed to have converted such Preferred Stock until immediately prior to the closing of such sale of securities. (d) SERIES A AND SERIES B CONVERSION PRICE ADJUSTMENTS. The Series A Conversion Price and Series B Conversion Price shall be subject to adjustment from time to time as follows: (i) (A) If the Corporation shall issue, after the Initial Series A Issue Date, any Additional Stock (as defined below) without consideration or for a consideration per share less than the Series A Conversion Price in effect immediately prior to the issuance of such Additional Stock, the Series A Conversion Price in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this clause (i)) be adjusted to a price determined by multiplying such Series A Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for such issuance would purchase at such Series A Conversion Price; and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of shares of such Additional Stock. If the Corporation shall issue, after the Initial Series B Issue Date, any Additional Stock without consideration or for a consideration per share less than the Series B Conversion Price in effect immediately prior to the issuance of such Additional Stock, the Series B Conversion Price in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this clause (i)) be adjusted to a price determined by multiplying such Series B Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for such issuance would purchase at such Series B Conversion Price; and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of shares of such Additional 9
Stock. For the purposes of this subsection, the number of shares of Common Stock outstanding immediately prior to suh issuance shall be calculated on a fully diluted basis, as if all shares of Series A Preferred Stock and Series B Preferred Stock and all Convertible Securities (as defined below) had been fully converted into shares of Common Stock immediately prior to such issuance and any outstanding Options (as defined below) had been fully exercised immediately prior to such issuance (and the resulting securities fully converted into shares of Common Stock, if so convertible) as of such date, but not including in such calculation any additional shares of Common Stock issuable with respect to shares of Series A Preferred Stock, Series B Preferred Stock and Convertible Securities or Options, solely as a result of the adjustment of the Series A Conversion Price or Series B Conversion Price resulting from the issuance of Additional Stock causing such adjustment. "Options" shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire either Common Stock or Convertible Securities. "Convertible Securities" shall mean any evidences of indebtedness, shares (other than Common Stock, Series A Preferred Stock and Series B Preferred Stock) or other securities convertible into or exchangeable for Common Stock. (B) No adjustment of the Series A Conversion Price or Series B Conversion Price shall be made in an amount less than one cent per share, provided that any adjustments which are not required to be made by reason of this sentence shall be carried forward and shall be either taken into account in any subsequent adjustment made prior to three (3) years from the date of the event giving rise to the adjustment being carried forward, or shall be made at the end of three (3) years from the date of the event giving rise to the adjustment being carried forward. Except to the limited extent provided for in Subsections 4(d)(i)(E)(3) and 4(d)(i)(E)(4) below, no adjustment of such Series A Conversion Price or Series B Conversion Price pursuant to this Subsection 4(d)(i) shall have the effect of increasing the Series A Conversion Price above the Series A Conversion Price in effect immediately prior to such adjustment and no adjustment of such Series B Conversion Price pursuant to this subsection 4(d)(i) shall have the effect of increasing the Series B Conversion Price above the Series B Conversion Price in effect immediately prior to such adjustment. (C) In the case of the issuance of Common Stock for cash, the consideration shall be deemed to be the amount of cash paid therefor before deducting any reasonable discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof. (D) In the case of the issuance of the Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair value thereof as determined by the Board of Directors irrespective of any accounting treatment. (E) In the case of the issuance (whether before, on or after the Initial Series A Issue Date or the Initial Series B Issue Date) of options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock or options to purchase or rights to subscribe for such convertible or exchangeable securities, the following provisions shall apply for all purposes of this Subsection 4(d)(i): 10
(1) The aggregate maximum number of shares of Common Stock deliverable upon exercise (assuming the satisfaction of any conditions to exercisability, including without limitation, the passage of time, but without taking into account potential antidilution adjustments) of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Subsections 4(d)(i)(C) and 4(d)(i)(D)), if any, received by the Corporation upon the issuance of such options or rights plus the minimum exercise price provided in such options or rights (without taking into account potential antidilution adjustments) for the Common Stock covered thereby. (2) The aggregate maximum number of shares of Common Stock deliverable upon conversion of or in exchange (assuming the satisfaction of any conditions to convertibility or exchangeability, including, without limitation, the passage of time, but without taking into account potential antidilution adjustments) for any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration, if any, received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum additional consideration, if any, to be received by the Corporation (without taking into account potential antidilution adjustments) upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in Subsections 4(d)(i)(C) and 4(d)(i)(D)). (3) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to the Corporation upon exercise of such options or rights or upon conversion of or in exchange for such convertible or exchangeable securities, including, but not limited to, a change resulting from the antidilution provisions thereof, the Series A Conversion Price and the Series B Conversion Price, to the extent in any way affected by or computed using such options, rights or securities, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities. (4) Upon the expiration of any such options or rights, the termination of any such rights to convert or exchange or the expiration of any options or rights related to such convertible or 11
exchangeable securities, the Series A Conversion Price and the Series B Conversion Price, to the extent in any way affected by or computed using such options, rights or securities or options or rights related to such securities, shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities which remain in effect) actually issued upon the exercise of such options or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities. (5) The number of shares of Common Stock deemed issued and the consideration deemed paid therefor pursuant to Subsections 4(d)(i)(E)(1) and (2) shall be appropriately adjusted to reflect any change, termination or expiration of the type described in either Subsection 4(d)(i)(E)(3) or (4). (F) "Additional Stock" shall mean any shares of Common Stock issued (or deemed to have been issued pursuant to Subsection 4(d)(i)(E)) by the Corporation after the Initial Series A Issue Date with respect to the Series A Conversion Price or after the Initial Series B Issue Date with respect to the Series B Conversion Price other than: (1) Common Stock issued pursuant to a transaction described in Subsection 4(d)(iii) hereof, (2) Common Stock issuable or issued to employees, consultants, directors or vendors (if in transactions with primarily non-financing purposes) of the Corporation directly or pursuant to a stock option plan or restricted stock plan approved by the Board of Directors, (3) Common Stock issuable in connection with lease lines, bank financings, acquisitions of companies or product lines or other similar transactions with a non-cash raising purpose approved by the Board of Directors (including, without limitation, the warrants to purchase 45,818 shares of Series A Preferred Stock issued to Imperial Bancorp in November 1997), (4) Common Stock issued upon conversion of the Preferred Stock, and (5) Common Stock issued or issuable: (i) in a public offering before or in connection with which all outstanding shares of Series A Preferred Stock and Series B Preferred Stock will be converted to Common Stock or (ii) upon exercise of warrants or rights granted to underwriters in connection with such a public offering. (ii) If the Corporation does not attain gross product revenues (on a full accrual basis) of at least $10,000,000 for its fiscal year 1999 ("1999 Gross Product Revenues") and upon publication by the Corporation of audited financial statements indicating 12
that such minimum 1999 Gross Product Revenues were not attained, the Series A Conversion Price (but not the Series B Conversion Price) shall forthwith be adjusted to a price equal to 70.83325% of the Series A Conversion Price in effect immediately preceding such publication. (iii) In the event the Corporation should at any time or from time to time, after the Initial Series B Issue Date, fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly, additional shares of Common Stock (hereinafter referred to as "Common Stock Equivalents") without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof), then, as of such record date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Series A Conversion Price and Series B Conversion Price shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of Series A Preferred Stock and Series B Preferred Stock shall be increased in proportion to such increase of the aggregate of shares of Common Stock outstanding and those issuable with respect to such Common Stock Equivalents. (iv) If the number of shares of Common Stock outstanding at any time, after the Initial Series B Issue Date, is decreased by a reverse split or combination of the outstanding shares of Common Stock, then, following the record date of such reverse split or combination, the Series A Conversion Price and Series B Conversion Price shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of each such series shall be decreased in proportion to such decrease in outstanding shares. (e) OTHER DISTRIBUTIONS. In the event the Corporation shall declare a dividend or distribution payable in securities of other persons, evidences of indebtedness issued by the Corporation or other persons, assets (excluding cash dividends) or Common Stock Equivalents, then, in each such case, the holders of the Series A Preferred Stock and Series B Preferred Stock shall be entitled to a proportionate share of any such distribution as though they were the holders of the number of shares of Common Stock of the Corporation into which their respective shares of Series A Preferred Stock and Series B Preferred Stock are convertible as of the record date fixed for the determination of the holders of Common Stock of the Corporation entitled to receive such dividend or distribution. (f) RECAPITALIZATIONS. If at any time or from time to time after the Initial Series B Issue Date, there shall be a recapitalization of the Corporation (other than a subdivision, combination or merger or sale of assets transaction provided for elsewhere in this Section 4 or in Section 2 above), provision shall be made so that the holders of the Series A Preferred Stock and Series B Preferred Stock shall thereafter be entitled to receive, upon conversion of their respective shares of Series A Preferred Stock and Series B Preferred Stock, the number of shares of stock or other securities or property of the Corporation or otherwise, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 4 with respect to the rights of the holders of the Series A Preferred 13
Stock and Series B Preferred Stock after the recapitalization to the end that the provisions of this Section 4 (including adjustment of the Series A Conversion Price and Series B Conversion Price then in effect and the number of shares issuable to such holders upon conversion of the Series A Preferred Stock and Series B Preferred Stock) shall be applicable after that event as nearly equivalent as may be practicable. (g) NO IMPAIRMENT. The Corporation will not, by amendment of its Certificate of Incorporation, as amended, or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock and Series B Preferred Stock against impairment. (h) NO FRACTIONAL SHARES AND CERTIFICATE AS TO ADJUSTMENTS. (i) No fractional shares shall be issued upon the conversion of any share or shares of the Series A Preferred Stock or Series B Preferred Stock, and the number of shares of Common Stock to be issued shall be rounded to the nearest whole share. Whether or not fractional shares are issuable upon such conversion shall be determined on the basis of the total number of shares of Series A Preferred Stock and Series B Preferred Stock which the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. (ii) Upon the occurrence of each adjustment or readjustment of the Series A Conversion Price or Series B Conversion Price pursuant to this Section 4, the Corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of such series of Preferred Stock for which the Conversion Price has been so adjusted a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Series A Preferred Stock or Series B Preferred Stock, furnish or cause to be furnished to such holder a like certificate setting forth: (A) such adjustment and readjustment, (B) the Conversion Price for such series at the time in effect and (C) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of a share of such series of Preferred Stock. (i) NOTICES OF RECORD DATE. In the event of any taking by the Corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, the Corporation shall mail to each holder of Series A Preferred Stock and Series B Preferred Stock, at least twenty (20) days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right. 14
(j) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of Series A Preferred Stock and Series B Preferred Stock, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Series A Preferred Stock and Series B Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of Series A Preferred Stock and Series B Preferred Stock, in addition to such other remedies as shall be available to the holder of such Series A Preferred Stock and Series B Preferred Stock, the Corporation will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to its Certificate of Incorporation, as amended. (k) NOTICES. Any notice required by the provisions of this Section 4 to be given to the holders of shares of Series A Preferred Stock or Series B Preferred Stock shall be deemed given if deposited in the United States mail, postage prepaid, and addressed to each holder of record at such holder's address appearing on the books of the Corporation. 5. VOTING RIGHTS. Each holder of shares of Series A Preferred Stock and Series B Preferred Stock shall have the right to one (1) vote for each share of Common Stock into which such holder's respective shares of Series A Preferred Stock and Series B Preferred Stock could then be converted, with full voting rights and powers equal to the voting rights and powers of the holders of Common Stock, except as required by law or as expressly provided herein, including the Protective Provisions in Section 6 below; shall be entitled, notwithstanding any provision hereof, to notice of any stockholders' meeting in accordance with the Bylaws of the Corporation; and shall be entitled to vote, together with holders of Common Stock, with respect to any question upon which holders of Common Stock have the right to vote, except as expressly provided herein. Fractional votes shall not, however, be permitted and any fractional voting rights available on an as-converted basis (after aggregating all shares into which shares of Series A Preferred Stock and Series B Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with 0.5 being rounded upward). 6. PROTECTIVE PROVISIONS. So long as any shares of Series A Preferred Stock or Series B Preferred Stock are outstanding, the Corporation shall not, without first obtaining the approval (by vote or written consent, as permitted by law) of the holders of at least sixty-seven percent (67%) of the then outstanding shares of Series A Preferred Stock and Series B Preferred Stock, voting or acting, as the case may be, as a single class: (a) sell, convey or otherwise dispose of all or substantially all of its property or business; liquidate, dissolve or wind up the Corporation's business; or merge into or consolidate with any other corporation (other than a wholly-owned subsidiary corporation); or effect any transaction or series of related transactions in which more than fifty percent (50%) of the voting power of the Corporation is disposed of (a "Corporate Transaction"), unless the Corporation's stockholders of record as constituted immediately prior to such Corporate Transaction will, immediately after such Corporate Transaction, hold at least fifty percent (50%) 15
of the voting power of the surviving or acquiring entity; provided, however, that shares of the surviving entity held by holders of the capital stock of the Corporation acquired by means other than the exchange or conversion of the capital stock of the Corporation for shares of the surviving entity shall not be used in determining if the stockholders of the Corporation own more than fifty percent (50%) of the voting power of the surviving or acquiring entity, but shall be used for determining the total outstanding voting power of such entity; (b) purchase, redeem or acquire any shares of Common Stock or options to purchase Common Stock or pay funds into or set aside or make available a sinking fund for the purchase, redemption or acquisition of shares of Common Stock or options to purchase Common Stock; provided, however, the foregoing restrictions shall not apply to the repurchase of shares of Common Stock held by employees, officers, directors, consultants or other persons performing services for the Corporation or any wholly owned subsidiary of the Corporation (including, but not by way of limitation, distributors and sales representatives) that are subject to restrictive agreements under which the Corporation has the option to repurchase such shares upon the occurrence of certain events, such as the proposed sale of such shares; (c) amend or modify any provision of the Corporation's Certificate of Incorporation, as amended, or Bylaws so as to affect adversely the rights, preferences or privileges of the Series A Preferred Stock or the Series B Preferred Stock; (d) amend the Bylaws of the Corporation to increase, or otherwise take any action that would have the effect of increasing, the authorized number of directors of the Corporation to more than five (5); (e) increase or decrease (other than by redemption or conversion) the total number of authorized shares of Series A Preferred Stock or Series B Preferred Stock; (f) authorize or issue, or authorize or effect any reclassification of, or obligate itself to issue, any equity security (other than the Series A Preferred Stock or Series B Preferred Stock), including any other security convertible into or exercisable for any equity security, so as to cause such security to have a preference over, or be on a parity with, the Series A Preferred Stock or the Series B Preferred Stock with respect to dividends or upon liquidation; (g) authorize or issue, or obligate itself to issue, any equity security, including any other security convertible into or exercisable for any equity security, of the Corporation to any employee of the Corporation, other than up to 10,561,808 shares of Common Stock (as adjusted to reflect stock dividends, stock splits, combinations, recapitalizations or the like after the date hereof) that may be reserved for issuance or otherwise issued under any stock option or other plan or agreement of the Corporation, together with options granted thereunder to purchase such shares; or (h) amend any of the provisions set forth in this Subsection 6. 7. STATUS OF CONVERTED OR REDEEMED STOCK. In the event any shares of Series A Preferred Stock or Series B Preferred Stock shall be converted pursuant to Section 4 above, or in the event any shares of Series A Preferred Stock or Series B Preferred Stock shall be redeemed pursuant to Section 3 above, the shares so converted or redeemed shall be canceled 16
and shall not be issuable by the Corporation. The Certificate of Incorporation, as amended, of the Corporation shall be amended at such time or times as the Corporation deems it reasonably practicable to effect the corresponding reduction in the Corporation's authorized capital stock. C. COMMON STOCK. 1. DIVIDEND RIGHTS. Subject to the provisions of Section 1 of Division (B) of this Article IV, the holders of the Common Stock shall be entitled to receive, when and as declared by the Board of Directors, out of any assets of the Corporation legally available therefor, such dividends as may be declared from time to time by the Board of Directors. 2. LIQUIDATION RIGHTS. Upon the liquidation, dissolution or winding up of the Corporation, the assets of the Corporation shall be distributed as provided in Section 2 of Division (B) of this Article IV. 3. REDEMPTION. The Common Stock is not redeemable hereunder. 4. VOTING RIGHTS. The holder of each share of Common Stock shall have the right to one vote, and shall be entitled to notice of any stockholders' meeting in accordance with the Bylaws of the Corporation, and shall be entitled to vote upon such matters and in such manner as may be provided by law. 4.2 Effective as of a Qualified Public Offering (as defined in Section B.8 of Section 4.1 above), the Corporation's capital stock shall be comprised as follows: A. AUTHORIZED SHARES. The aggregate number of shares that the Corporation shall have authority to issue is 260,000,000, (a) 250,000,000 shares of which shall be Common Stock, par value $0.0001 per share, and (b) 10,000,000 of which shall be Preferred Stock, par value $0.0001 per share. B. COMMON STOCK. Each share of Common Stock shall have one vote on each matter submitted to a vote of the stockholders of the Corporation. Subject to the provisions of applicable law and the rights of the holders of the outstanding shares of Preferred Stock, if any, the holders of shares of Common Stock shall be entitled to receive, when and as declared by the Board of Directors of the Corporation, out of the assets of the Corporation legally available therefor, dividends or other distributions, whether payable in cash, property or securities of the Corporation. The holders of shares of Common Stock shall be entitled to receive, in proportion to the number of shares of Common Stock held, the net assets of the Corporation upon dissolution after any preferential amounts required to be paid or distributed to holders of outstanding shares of Preferred Stock, if any, are so paid or distributed. C. PREFERRED STOCK. 1. SERIES. The Preferred Stock may be issued from time to time by the Board of Directors as shares of one or more series. The description of shares of each additional series of Preferred Stock, including any designations, preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends, qualifications, and terms and conditions of redemption shall be as set forth in resolutions adopted by the Board of Directors. 17
2. RIGHTS AND PREFERENCES. The Board of Directors is expressly authorized, at any time, by adopting resolutions providing for the issuance of, or providing for a change in the number of, shares of any particular series of Preferred Stock and, if and to the extent from time to time required by law, by filing certificates of amendment or designation which are effective without stockholder action, to increase or decrease the number of shares included in each series of Preferred Stock, but not below the number of shares then issued, and to set in any one or more respects the designations, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications, or terms and conditions of redemption relating to the shares of each such series. The authority of the Board of Directors with respect to each series of Preferred Stock shall include, but not be limited to, setting or changing the following: (a) the dividend rate, if any, on shares of such series, the times of payment and the date from which dividends shall be accumulated, if dividends are to be cumulative; (b) whether the shares of such series shall be redeemable and, if so, the redemption price and the terms and conditions of such redemption; (c) the obligation, if any, of the Corporation to redeem shares of such series pursuant to a sinking fund; (d) whether shares of such series shall be convertible into, or exchangeable for, shares of stock of any other class of classes and, if so, the terms and conditions of such conversion or exchange, including the price or prices or the rate or rates of conversion or exchange and the terms of adjustment, if any; (e) whether the shares of such series shall have voting rights, in addition to the voting rights provided by law, and, if so, the extent of such voting rights; (f) the rights of the shares of such series in the event of voluntary or involuntary liquidation, dissolution or winding-up of the Corporation; and (g) any other relative rights, powers, preferences, qualifications, limitations or restrictions thereof relating to such series. ARTICLE V A director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (a) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the Delaware General Corporation Law or (d) for any transaction from which the director derived any improper personal benefit. If the Delaware General Corporation Law is amended after approval by the stockholders of this Article to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law as so amended. 18
ARTICLE VI The management of the business and the conduct of the affairs of the Corporation shall be vested in its Board of Directors. The number of directors which shall constitute the whole Board of Directors shall be fixed by, or in the manner provided in, the Bylaws of the Corporation. ARTICLE VII Meetings of stockholders may be held within or without the State of Delaware, as the Bylaws may provide. The books of the Corporation may be kept (subject to any provision contained in the statutes) outside the State of Delaware at such place or places as may be designated from time to time by the Board of Directors or in the Bylaws of the Corporation. ARTICLE VIII Election of directors at an annual or special meeting of stockholders need not be by written ballot unless the Bylaws of the Corporation shall so provide. ARTICLE IX A. At each annual meeting of stockholders, directors of the Corporation shall be elected to hold office until the expiration of the term for which they are elected, and until their successors have been duly elected and qualified. At the first annual meeting of stockholders following the closing of the initial public offering (the "FIRST PUBLIC COMPANY ANNUAL MEETING") of the Corporation's capital stock pursuant to an effective registration statement filed under the Securities Act of 1933, as amended (the "INITIAL PUBLIC OFFERING"), the directors of the Corporation shall be divided into three classes as nearly equal in size as is practicable, hereby designated as Class I, Class II and Class III. The term of office of the initial Class I directors shall expire at the next succeeding annual meeting of stockholders, the term of office of the initial Class II directors shall expire at the second succeeding annual meeting of stockholders and the term of office of the initial Class III directors shall expire at the third succeeding annual meeting of stockholders. For the purposes hereof, the initial Class I, Class II and Class III directors shall be those directors designated and elected at the First Public Company Annual Meeting. At each annual meeting after the First Public Company Annual Meeting, directors to replace those of a Class whose terms expire at such annual meeting shall be elected to hold office until the third succeeding annual meeting and until their respective successors shall have been duly elected and qualified. If the number of directors is hereafter changed, any newly created directorships or decrease in directorships shall be so apportioned among the classes as to make all classes as nearly equal in number as is practicable. B. Vacancies occurring on the Board of Directors for any reason may be filled by vote of a majority of the remaining members of the Board of Directors, although less than a quorum, at a meeting of the Board of Directors. A person so elected by the Board of Directors to fill a vacancy shall hold office until the next succeeding annual meeting of stockholders of the Corporation and until his or her successor shall have been duly elected and qualified. 19
ARTICLE X In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to make, alter, amend or repeal the Bylaws of the Corporation. ARTICLE XI Effective upon the closing of the Initial Public Offering, stockholders of the Corporation may not take action by written consent in lieu of a meeting but must take any actions at a duly called annual or special meeting. ARTICLE XII Notwithstanding any other provisions of this Certificate of Incorporation or any provision of law which might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of the capital stock required by law or this Certificate of Incorporation, the affirmative vote of the holders of at least two-thirds (2/3) of the combined voting power of all of the then-outstanding shares of the Corporation entitled to vote shall be required to alter, amend or repeal Articles IX, XI or XII, or any provisions thereof. ARTICLE XIII The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred on stockholders herein are granted subject to this reservation. * * * 20
Exhibit 10.17 NEITHER THIS WARRANT NOR ANY OF THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAW. NO TRANSFER OF THIS WARRANT OR OF THE SECURITIES ISSUABLE UPON EXERCISE HEREOF SHALL BE VALID OR EFFECTIVE UNLESS (A) SUCH TRANSFER IS MADE PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAW, OR (B) THE HOLDER SHALL DELIVER TO THE COMPANY AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND OF ANY APPLICABLE STATE SECURITIES LAW. WARRANT NO. B-001 SEPTEMBER ____, 1998 SILICON LABORATORIES INC. PREFERRED STOCK PURCHASE WARRANT Silicon Laboratories Inc., a Delaware corporation (the "COMPANY"), hereby grants to Imperial Bank ("PURCHASER"), or its registered assigns or transferees (Purchaser and each such assign or transferee being referred to herein as a "HOLDER" and collectively as the "HOLDERS") the right to purchase, at any time and from time to time on and after the date hereof until the fifth (5th) anniversary of the date hereof (the "EXPIRATION DATE"), up to 4,765 fully paid and non-assessable shares of Series B Convertible Preferred Stock of the Company, par value $0.0001 per share (the "SERIES B PREFERRED STOCK"), on the terms and subject to the conditions set forth below. 1. EXERCISE AND VESTING OF WARRANT. 1.1. EXERCISE PRICE. Subject to adjustment as hereinafter provided, the rights represented by this Preferred Stock Purchase Warrant (this "WARRANT") are exercisable on and after the date hereof (the "EXERCISE DATE") until the Expiration Date, at a price (the "EXERCISE PRICE") of $4.76 per share of the Series B Preferred Stock issuable hereunder (hereinafter, the "WARRANT SHARES"). The Exercise Price shall be payable in cash, or by certified or official bank check. 1.2. METHOD OF EXERCISE. Upon surrender of this Warrant with a duly executed Notice of Exercise in the form of ANNEX A attached hereto, together with payment of the Exercise Price for the Warrant Shares purchased (except to the extent of conversion pursuant to Section 1.3 herein), at the Company's principal executive offices (presently located at 2024 East St. Elmo Road, Austin, Texas 78744-1018) or at such other address as the Company shall have advised the Holder in writing (the "DESIGNATED OFFICE"), the Holder shall be entitled to receive a
certificate or certificates for the Warrant Shares so purchased. The Company agrees that the Warrant Shares shall be deemed to have been issued to the Holder as of the close of business on the date on which this Warrant shall have been surrendered together with the Notice of Exercise and payment for such Warrant Shares. 1.3. CONVERSION RIGHT. In lieu of exercising this Warrant as specified in Section 1.2, Holder may from time to time convert this Warrant, in whole or in part, into a number of Warrant Shares determined by dividing (a) the aggregate fair market value of the Warrant Shares or other securities otherwise issuable upon exercise of this Warrant minus the aggregate Exercise Price of such Warrant Shares by (b) the fair market value of one Warrant Share. The fair market value of the Warrant Shares shall be determined pursuant to Section 1.4. 1.4. VALUATION. If the Warrant Shares are traded regularly in a public market, the fair market value of the Warrant Shares shall be the closing price of the Warrant Shares (or the closing price of the Company's stock into which the Warrant Shares are convertible) reported for the business day immediately before Holder delivers its Notice of Exercise to the Company. If the Warrant Shares are not regularly traded in a public market, the Board of Directors of the Company shall determine fair market value in its reasonable good faith judgment. The foregoing notwithstanding, if Holder advises the Board of Directors of the Company in writing that Holder disagrees with such determination, then the Company and Holder shall promptly agree upon a reputable investment banking firm to undertake such valuation. If the valuation of such investment banking firm is greater than that determined by the Board of Directors of the Company, then all fees and expenses of such investment banking firm shall be paid by the Company. In all other circumstances, such fees and expenses shall be paid by Holder. 2. TRANSFER; ISSUANCE OF STOCK CERTIFICATES; RESTRICTIVE LEGENDS. 2.1. TRANSFER. Subject to compliance with the restrictions on transfer set forth in this Section 2, each transfer of this Warrant and all rights hereunder, in whole or in part, shall be registered on the books of the Company to be maintained for such purpose, upon surrender of this Warrant at the Designated Office, together with a written assignment of this Warrant in the form of ANNEX B attached hereto duly executed by the Holder or its agent or attorney. Upon such surrender and delivery, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, if any. A Warrant, if properly assigned in compliance with the provisions hereof, may be exercised by the new Holder for the purchase of Warrant Shares without having a new Warrant issued. Prior to due presentment for registration of transfer thereof, the Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof (notwithstanding any notations of ownership or writing thereon made by anyone other than a duly authorized officer of the Company) for all purposes and shall not be affected by any notice to the contrary. All Warrants issued upon any assignment of Warrants shall be the valid obligations of the Company, evidencing the same rights, and entitled to the 2
same benefits as the Warrants surrendered upon such registration of transfer or exchange. 2.2. STOCK CERTIFICATES. Certificates for the Warrant Shares shall be delivered to the Holder within a reasonable time after the rights represented by this Warrant shall have been exercised pursuant to Section 1, and a new Warrant representing the shares of Series B Preferred Stock, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder within such time. The issuance of certificates for Warrant Shares upon the exercise of this Warrant shall be made without charge to the Holder hereof including, without limitation, any documentary, stamp or similar tax that may be payable in respect thereof, PROVIDED, HOWEVER, that the Company shall not be required to pay any income tax to which the Holder hereof may be subject in connection with the issuance of this Warrant or the Warrant Shares; AND PROVIDED FURTHER, that if Warrant Shares are to be delivered in a name other than the name of the Holder hereof representing any Warrant being exercised, then no such delivery shall be made unless the person requiring the same has paid to the Company the amount of transfer taxes or charges incident thereto, if any. 2.3. RESTRICTIVE LEGENDS. (a) Except as otherwise provided in this Section 2, each certificate for Warrant Shares initially issued upon the exercise of this Warrant, and each certificate for Warrant Shares issued to any subsequent transferee of any such certificate, shall be stamped or otherwise imprinted with a legend in substantially the following form: THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL SUCH SECURITIES ARE REGISTERED UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY IS OBTAINED TO THE EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED. (b) Except as otherwise provided in this Section 2, each Warrant shall be stamped or other-wise imprinted with a legend in substantially the following form: NEITHER THIS WARRANT NOR ANY OF THE SECURITIES ISSUABLE UPON EXERCISE THEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAW, NO TRANSFER OF THIS WARRANT OR OF THE SECURITIES ISSUABLE UPON EXERCISE HEREOF SHALL BE VALID OR EFFECTIVE UNLESS (A) SUCH TRANSFER IS MADE PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAW, OR (B) THE HOLDER SHALL DELIVER TO THE COMPANY AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND OF ANY APPLICABLE STATE 3
SECURITIES LAW. Notwithstanding the foregoing, the legend requirements of this Section 2.3 shall terminate as to any particular Warrant or Warrant Share when the Company shall have received from the Holder thereof an opinion of counsel in form and substance reasonably acceptable to the Company that such legend is not required in order to ensure compliance with the Securities Act. Whenever the restrictions imposed by this Section 2.3 shall terminate, the Holder hereof or of Warrant Shares, as the case may be, shall be entitled to receive from the Company without cost to such Holder a new Warrant or certificate for Warrant Shares of like tenor, as the case may be, without such restrictive legend. 3. ADJUSTMENT OF NUMBER OF SHARES; EXERCISE PRICE; NATURE OF SECURITIES ISSUABLE UPON EXERCISE OF WARRANTS. 3.1. EXERCISE PRICE; ADJUSTMENT OF NUMBER OF SHARES. The Exercise Price set forth in Section 1 hereof and the number of shares purchasable hereunder shall be subject to adjustment from time to time as hereinafter provided. 3.2. CONVERSION OF SERIES B SHARES. If all of the Company's Series B Preferred Stock shall be, or if outstanding would be, at any time prior to the Expiration Date, converted into shares of the Company's Common Stock, then the unexercised portion of this Warrant shall be converted into the right to purchase that number of shares of the Company's Common Stock equal to the number of shares of the Common Stock that would have been received if this Warrant had been exercised in full and the Series B Preferred Stock received thereupon had been simultaneously converted immediately prior to such event, and the Exercise Price shall be immediately adjusted to equal the quotient obtained by dividing (x) the aggregate Exercise Price of the maximum number of shares of Series B Preferred Stock for which this Warrant was exercisable immediately prior to such conversion, by (y) the number of shares of Common Stock for which this Warrant is exercisable immediately after such conversion; provided, however, that in no event shall the Exercise Price as so adjusted be less than the par value of the Common Stock. 3.3. MERGER, SALE OF ASSETS, ETC. If at any time while this Warrant, or any portion thereof, is outstanding and unexpired there shall be a reorganization (other than a combination, reclassification, exchange, or subdivision of shares as provided in Sections 3.4 and 3.5), merger or consolidation of the Company with or into another corporation in which the Company is not the surviving entity, or a merger in which the Company is the surviving entity but the shares of the Company's capital stock outstanding immediately prior to the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, or a sale or transfer of the Company's properties and assets as, or substantially as, an entirety to any other person, then, as a part of such reorganization, merger, consolidation, sale or transfer, lawful provision shall be made so that the Holder of this Warrant shall thereafter be entitled to receive upon exercise of this Warrant, during the period specified herein and upon 4
payment of the Exercise Price then in effect, the number of shares of stock or other securities or cash or property of the successor corporation resulting from such reorganization, merger, consolidation, sale or transfer that a Holder of the shares deliverable upon exercise of this Warrant would have been entitled to receive in such reorganization, consolidation, merger, sale or transfer if this Warrant had been exercised immediately before such reorganization, consolidation, merger, sale or transfer, all subject to further adjustment as provided in this Section 3. The foregoing provisions of this Section 3.3 shall similarly apply to successive reorganizations, consolidations, mergers, sales and transfers and to the stock and securities of any other corporation that are at the time receivable upon the exercise of this Warrant. If the per-share consideration payable to the Holder hereof for shares in connection with any such transaction is in a form other than cash or securities, then the value of such consideration shall be determined in good faith by the Company's Board of Directors. In all events, appropriate adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder hereof after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as reasonably may be, in relation to any shares or other property deliverable after that event upon exercise of this Warrant. 3.4. RECLASSIFICATION, ETC. If the Company, at any time while this Warrant, or any portion thereof, remains outstanding and unexpired, shall, by the reclassification or exchange of securities or otherwise, change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities of any other class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights under this Warrant immediately prior to such reclassification, exchange or other change and the Exercise Price therefor shall be appropriately adjusted, all subject to further adjustment as provided in this Section 3. No adjustment shall be made pursuant to this Section 3.4, upon any conversion of the Series B Preferred Stock which is the subject of Section 3.2. 3.5. STOCK SPLITS, STOCK DIVIDENDS AND REVERSE STOCK SPLITS. In case at any time the Company shall split or subdivide the outstanding shares of Series B Preferred Stock into a greater number of shares, or shall declare and pay any stock dividend with respect to its outstanding stock that has the effect of increasing the number of outstanding shares of Series B Preferred Stock, the Exercise Price in effect immediately prior to such subdivision or stock dividend shall be proportionately reduced (but not below the par value of the Series B Preferred Stock) and the number of Warrant Shares purchasable pursuant to this Warrant immediately prior to such subdivision or stock dividend shall be proportionately increased, and conversely, in case at any time the Company shall combine its outstanding shares of Series B Preferred Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares purchasable upon the exercise of this Warrant immediately prior to such combination shall be proportionately reduced. 4. REGISTRATION; EXCHANGE AND REPLACEMENT OF WARRANT; RESERVATION OF SHARES. 5
The Company shall keep at the Designated Office a register in which the Company shall provide for the registration, transfer and exchange of this Warrant. The Company shall not at any time, except upon the dissolution, liquidation or winding-up of the Company, close such register so as to result in preventing or delaying the exercise or transfer of this Warrant. The Company may deem and treat the person in whose name this Warrant is registered as the Holder and owner hereof for all purposes and shall not be affected by any notice to the contrary, until presentation of this Warrant for registration or transfer as provided in this Section 4. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant and (in case of loss, theft or destruction) of indemnity satisfactory to it, and (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will (in the absence of notice to the Company that the Warrant has been acquired by a BONA FIDE purchaser) make and deliver a new Warrant of like tenor, in lieu of this Warrant without requiring the posting of any bond or the giving of any security. The Company shall at all times reserve and keep available out of its authorized shares of Series B Preferred Stock, solely for the purpose of issuance upon the exercise of this Warrant, such number of shares of Series B Preferred Stock as shall be issuable upon the exercise hereof. The Company covenants and agrees that, upon exercise of this Warrant and payment of the Exercise Price therefor, all Warrant Shares issuable upon such exercise shall be duly and validly issued, fully paid and non-assessable. 5. FRACTIONAL WARRANTS AND FRACTIONAL SHARES. If the number of Warrant Shares purchasable upon the exercise of this Warrant is adjusted pursuant to Section 3 hereof, the Company shall nevertheless not be required to issue fractions of shares, upon exercise of this Warrant or otherwise, or to distribute certificates that evidence fractional shares. With respect to any fraction of a share called for upon any exercise hereof, the Company shall pay to the Holder an amount in cash equal to such fraction multiplied by the current market value of such fractional share as may be prescribed by the Board of Directors of the Company. 6. WARRANT HOLDERS NOT DEEMED STOCKHOLDERS. No Holder of this Warrant shall, as such, be entitled to vote or to receive dividends or be deemed the Holder of Warrant Shares that may at any time be issuable upon exercise of this Warrant for any purpose whatsoever, nor shall anything contained herein be construed to confer upon the Holder of this Warrant, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any 6
recapitalization, issue or reclassification of stock, change of par value or change of stock to no par value, consolidation, merger or conveyance or otherwise), or to receive notice of meetings, or to receive dividends or subscription rights, until such Holder shall have exercised this Warrant and been issued Warrant Shares in accordance with the provisions hereof. 7. NOTICES. All notices, requests, consents and other communications hereunder shall be in writing and shall be deemed to have been duly made when delivered personally, or mailed by registered or certified mail, return receipt requested, or telecopied or telexed and confirmed in writing and delivered personally or mailed by registered or certified mail, return receipt requested (a) if to the Holder of this Warrant, to the address of such Holder as shown on the books of the Company, or (b) if to the Company, to the address set forth in Section 1.2 of this Warrant; or at such other address as the Holder or the Company may hereafter have advised the other. 8. SUCCESSORS.
