THE ACCOMPANYING NOTES ARE AN INTEGRAL PART OF THESE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS. 4 SILICON LABORATORIES INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) SEPTEMBER 29, 2001 1. SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The condensed consolidated financial statements included herein are unaudited; however, they contain all normal recurring accruals and adjustments which, in the opinion of management, are necessary to present fairly the consolidated financial position of Silicon Laboratories Inc. and its subsidiaries (collectively, the "Company") at September 29, 2001 and September 30, 2000, the consolidated results of its operations for the three and nine months ended September 29, 2001 and September 30, 2000 and the consolidated statements of cash flows for the nine months ended September 29, 2001 and September 30, 2000. All intercompany accounts and transactions have been eliminated. The results of operations for the three and nine months ended September 29, 2001 are not necessarily indicative of the results to be expected for the full year. The accompanying unaudited condensed consolidated financial statements do not include footnotes and certain financial presentations normally required under accounting principles generally accepted in the United States. Therefore, these financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 30, 2000, included in the Company's Form 10-K filed with the Securities and Exchange Commission. 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):
SEPTEMBER 29, December 30, 2001 2000 ------------------- ------------------- Work in progress........ $4,112 $4,302 Finished goods.......... 1,722 2,917 ------------------- ------------------- $5,834 $7,219 =================== ===================
OTHER COMPREHENSIVE INCOME There were no material differences between net income (loss) and comprehensive income (loss) during any of the periods presented. RECENT ACCOUNTING PRONOUNCEMENTS In July 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) Nos. 141 and 142, BUSINESS COMBINATIONS and GOODWILL AND OTHER INTANGIBLE ASSETS. SFAS No. 141 replaces Accounting Principles Board Opinion (APB) No. 16 and eliminates pooling-of-interests accounting prospectively. It also provides guidance on purchase accounting related to the recognition of intangible assets and accounting for negative goodwill. SFAS No. 142 changes the accounting for goodwill from an amortization method to an impairment-only approach. Under SFAS No. 142, goodwill will be tested annually and whenever events or circumstances occur indicating that goodwill might be impaired. SFAS No. 141 and SFAS No. 142 are effective for all business combinations completed after June 30, 2001. Upon adoption of SFAS No. 142, amortization of goodwill recorded for business combinations consummated prior to July 1, 2001 will cease, and intangible assets acquired prior to July 1, 2001 that do not meet the criteria for recognition under SFAS No. 141 will be reclassified to goodwill. Companies are required to adopt SFAS No. 142 for fiscal years beginning after December 15, 2001, but early adoption is permitted. The Company will adopt SFAS No. 142 on December 30, 2001, the beginning of fiscal 2002. In connection with the adoption of SFAS No. 142, the Company will be required to perform a transitional goodwill impairment assessment. The adoption of SFAS No. 141 and SFAS No. 142 will not have a material impact on the Company's results of operations and financial position since the Company's existing balances of goodwill and other intangible assets are not significant due to impairment charges recorded during the quarter ended September 29, 2001 under SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF. 5 SILICON LABORATORIES INC.

2. SEGMENT REPORTING The Company has one operating segment, integrated circuits (ICs), with three product areas (Wireline, Wireless, and Optical Networking). 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 a majority of the revenues in all periods presented. 3. COMMITMENTS AND CONTINGENCIES 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 or results of operations. On August 7, 2001, TDK Semiconductor Corporation commenced a lawsuit against the Company for alleged willful infringement by our DAA products of a TDK-held patent. TDK's complaint seeks unspecified treble damages, costs and attorneys' fees, and an injunction. On September 27, 2001, we served and filed an answer to their complaint, in which we denied infringement and asserted that their patent is invalid. This lawsuit may involve significant expense and may also divert our 6 SILICON LABORATORIES INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) management's time and attention from other aspects of our business. Due to the inherent uncertainties of litigation, we are unable to predict the outcome of this matter. 4. GOODWILL AND OTHER INTANGIBLE ASSETS The components of intangible assets are as follows (in thousands):

The Company, as part of its review of financial results for the three months ended September 29, 2001, performed an assessment of the carrying value of the Company's long-lived assets to be held and used including significant amounts of goodwill and other intangible assets recorded in connection with our acquisitions of Krypton Isolation, Inc. "Krypton" and SNR Semiconductor, Inc. "SNR". The assessment was performed pursuant to Statement Financial Accounting Standards No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF because of the recent appearance of several impairment indicators: - The revenue stream associated with the Krypton business has decreased significantly since the acquisition; - Krypton customers have effectively stopped purchasing Krypton products; - The Krypton office was closed in August of 2001 and most of the workforce is no longer employed by the Company; - The Company determined that further development or alternative uses of the acquired technologies were remote; and - The Company does not expect to have any significant future cash flows related to these acquired assets. The conclusion of that assessment was that the acquired assets were permanently impaired. As a result, the Company recorded a charge of $33.3 million and $1.6 million to reduce goodwill and other intangible assets, respectively, based on the amount by which the carrying amount of the assets exceeded their fair market value. Fair value was determined based on discounted future cash flows for assets that had separately identifiable cash flows. ITEM 2.

OUR FISCAL YEAR-END FINANCIAL REPORTING PERIODS ARE A 52- OR 53- WEEK YEAR ENDING ON THE SATURDAY CLOSEST TO DECEMBER 31ST. 7 OUR THIRD QUARTER OF FISCAL YEAR 2001 ENDED SEPTEMBER 29, 2001. OUR THIRD QUARTER OF FISCAL YEAR 2000 ENDED SEPTEMBER 30, 2000. ALL OF THE QUARTERLY PERIODS REPORTED IN THIS QUARTERLY REPORT ON FORM 10-Q HAD THIRTEEN WEEKS. OVERVIEW We design and develop proprietary, analog-intensive, mixed-signal integrated circuits, or ICs, for the communications industry. Our innovative ICs can dramatically reduce the cost, size and system power requirements of the products that our customers sell to their end-user customers. We currently offer ICs that can be incorporated into communications devices, such as modems and wireless phones, as well as cable and satellite set-top boxes, residential communication gateways for cable or DSL, cable modems and optical networking equipment. Customers during fiscal 2000 included 3Com, Agere Systems (formerly the Lucent Microelectronics business), Motorola, PC-TEL, and Smart Link. Our company was founded in 1996. Our business has grown rapidly since our inception, as reflected by our employee headcount, which increased to 270 employees at September 29, 2001, from 256 at the end of fiscal 2000, 148 at the end of fiscal 1999, 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 three principal product areas, the Wireline Products Division, the Wireless Products Division, and the Optical Networking 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. A majority 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 recent periods, we have expanded our product lines. For example, the Wireline Products Division has introduced our ISOmodem product providing a complete embedded modem solution for fast connection, low speed applications and our ProSLIC product providing the telephone features at the source end of the telephone for subscriber line interfaces in voice-over-digital network applications. Our Wireless Products Division has introduced RF synthesizer products serving GSM mobile telephone applications, wideband CDMA applications and wireless local area network opportunities. In addition, this Division introduced a GSM transceiver product to address GSM mobile telephone applications. Our Optical Networking Products Division introduced a family of products suitable for SONET physical layer applications. We expect to 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. Since our inception, a few customers have accounted for a substantial portion of our revenues. During fiscal 2000, PC-TEL accounted for 46% of our revenues. No other customer accounted for more than 10% of our revenues in fiscal 2000. To date, a majority of our sales have been generated through our direct sales force. In fiscal 1998, we began to establish a network of independent sales representatives and distributors worldwide to support our sales and marketing activities. We anticipate that revenues from these representatives and distributors will increase as a percentage of our total revenues 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. During the first half of fiscal 2001, many personal computer manufacturers announced cutbacks in their sales forecasts due to rapid deterioration in industry-wide demand, resulting in a major inventory correction. This downturn had a significant negative impact on our results for the three and nine months ended September 29, 2001. We believe that this decrease in demand will also have a sizable impact on our results from operations, particularly within our Wireline Products Division, for the year ending December 29, 2001 and creates significant uncertainty in our business planning for the remainder of the year. 8 The percentage of our revenues derived from customers located outside of the United States was 67% in the nine months ended September 29, 2001, 21% in fiscal 2000, 7% in fiscal 1999 and was insignificant in fiscal 1998. All of our revenues to date have been denominated in U.S. dollars. We believe that the percentage of our revenues derived from customers outside of the United States will continue to increase 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. We expect this sales cycle to lengthen as our customers experience a decrease in demand for their products due to the ongoing economic downturn that is particularly affecting technology companies. 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 revenues, 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 revenues 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 make 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 wireless telephones, we expect that the demand for our products will be subject to seasonal demand resulting in increased sales in the third and fourth quarters of each year when customers place orders to meet holiday demand. The following describes the line items set forth in our consolidated statements of operations: REVENUES. Revenues are generated principally by sales of our ICs. We recognize revenue upon the transfer of title, which generally occurs upon shipment to our customers. Revenues are deferred on shipments to distributors until they are resold by such distributors. Our products typically carry a one-year replacement warranty. Our revenues are subject to variation from period to period due to the volume of shipments made within a period and the prices we charge for our products. The vast majority of our revenues were negotiated at prices that reflect a discount from the list prices for our products. These discounts are made for a variety of reasons, including to establish a relationship with a new customer, as an incentive for customers to purchase products in larger volumes or in response to competition. In addition, as a product matures, we expect that the average selling price for that product will decline due to the greater availability of competing products. Therefore, our ability to increase revenues in the future is dependent on increased demand for our established products and our ability to ship larger volumes of those products in response to such demand, as well as customer acceptance of newly introduced products. COST OF REVENUES. Cost of revenues includes the cost of purchasing finished silicon wafers processed by independent foundries; costs associated with assembly, test and shipping of those products; costs of personnel and equipment associated with manufacturing support, logistics and quality assurance; an allocated portion of our occupancy costs; and allocable depreciation of testing equipment and leasehold improvements. Generally, we depreciate equipment over four years on a straight line basis. We also depreciate our leasehold improvements over the shorter of the estimated useful life or the applicable lease term. Recently introduced products tend to have higher cost of revenues per unit due to initially low production volumes required by our customers and higher costs associated with new package variations. Generally, as production volumes for a product increase, unit production costs tend to decrease as our 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. 9 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 design of new products and creation of test methodologies to assure compliance with required specifications. SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative expense consists primarily of personnel-related expenses, related allocable portion of our occupancy costs, sales commissions to independent sales representatives, professional fees, directors and officers liability insurance, other promotional and marketing expenses and reserves for bad debt. Write offs of uncollectible accounts have been insignificant to date. WRITE OFF OF IN-PROCESS RESEARCH & DEVELOPMENT. Write off of in-process research & development reflects the write off of in-process research and development costs acquired in connection with our acquisition of Krypton. GOODWILL AMORTIZATION. Goodwill amortization includes the amortization of goodwill purchased in connection with our acquisitions of Krypton and SNR. Goodwill is amortized over four to five years using the straight line method. IMPAIRMENT OF GOODWILL AND OTHER INTANGIBLE ASSETS. Impairment of goodwill and other intangible assets reflects the charge to write-down that portion of the carrying value of goodwill and other intangible assets that is in excess of their fair market value. 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, representing, for accounting purposes, 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. The deferred stock compensation is amortized over the vesting period of the applicable options or shares, generally five to eight years. The amortization of deferred stock compensation is recorded as an operating expense. INTEREST INCOME. Interest income reflects interest earned on average cash, cash equivalents and investment balances. INTEREST EXPENSE. Interest expense consists of interest on our long-term debt and capital lease obligations. PROVISION (BENEFIT) FOR INCOME TAXES. We accrue a provision (benefit) for federal and state income tax at the applicable statutory rates. 10 RESULTS OF OPERATIONS The following table sets forth our statement of operations data as a percentage of revenues for the periods indicated:

COMPARISON OF THE THREE AND NINE MONTHS ENDED SEPTEMBER 29, 2001 TO THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2000. REVENUES. Revenues for the quarter ended September 29, 2001 were $19.9 million, a decrease of $9.5 million or 32.3% from revenues of $29.4 million in the quarter ended September 30, 2000. Revenues for the nine months ended September 29, 2001 were $50.5 million, a decrease of $22.9 million or 31.2% from revenues of $73.4 million in the nine months ended September 30, 2000. The decreases were primarily due to a decline in the sales volume of our DAA family of products reflecting the rapid deterioration in demand within the personal computer industry. Revenues from non-DAA products, such as the ISOmodem, the ProSLIC, the RF Synthesizer and our optical networking products, accounted for approximately 42.8% of revenues for the quarter ended September 29, 2001 as compared to 15% of revenues for the quarter ended September 30, 2000. GROSS PROFIT. Gross profit for the quarter ended September 29, 2001 was $11.4 million or 57.3% of revenues, a decrease of $7.9 million or 40.9% as compared with gross profit of $19.3 million or 65.6% of revenues in the quarter ended September 30, 2000. Gross profit for the nine months ended September 29, 2001 was $28.1 million or 55.8% of revenues, a decrease of $20.0 million or 41.6% as compared with gross profit of $48.1 million or 65.6% of revenues in the nine months ended September 30, 2000. The decreases in gross profit were primarily due to the substantial decrease in sales volume, decreased utilization of our testing capacity and reserves for excess inventory due to demand fluctuations for our products. With respect to the nine months ended September 29, 2001, these negative influences on gross profit were partially offset by a vendor credit received during the quarter ended March 31, 2001 for yield variations outside processing parameters. The future direction of gross margins is uncertain due to many factors such as the severity and duration of the personal computer industry downturn, our ability to sell existing inventory on hand, our ability to successfully introduce to market and sell new products, the selling prices for existing and new products, the extent to which our competitors introduce new products to market, and future product cost considerations with our vendors. 11 RESEARCH AND DEVELOPMENT. Research and development expense for the quarter ended September 29, 2001 was $7.7 million or 38.7% of revenues, which reflected an increase of $2.4 million or 45.3% as compared with research and development expense of $5.3 million or 17.9% of revenues for the quarter ended September 30, 2000. Research and development expense for the nine months ended September 29, 2001 was $21.3 million or 42.2% of revenues, which reflected an increase of $8.0 million or 60.2% as compared with research and development expense of $13.3 million or 18.1% of revenues for the nine months ended September 30, 2000. The increases in the dollar amount of research and development expense were principally due to continued product development activities, significant increases in new product development initiatives in wireless and optical networking opportunities, usage of more expensive advanced silicon CMOS processes, and increased spending to develop test methodologies for new products. As a percentage of revenues, research and development expense increased significantly due to the substantial decrease in sales volume for the three and nine months ended September 29, 2001. We expect that research and development expense will continue to increase in absolute dollars in future periods as we develop new ICs, and may fluctuate as a percentage of revenues due to changes in sales volume and new product development initiatives. SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative expense for the quarter ended September 29, 2001 was $5.4 million or 27.1% of revenues, which reflected an increase of $0.3 million or 5.9% as compared to selling, general and administrative expense of $5.1 million or 17.4% of revenues in the quarter ended September 30, 2000. Selling, general and administrative expense for the nine months ended September 29, 2001 was $14.2 million or 27.9% of revenues, which reflected an increase of $1.5 million or 11.8% as compared to selling, general and administrative expense of $12.7 million or 17.3% of revenues in the nine months ended September 30, 2000. The increases in the dollar amount of selling, general and administrative expense were principally attributable to increased staffing, but were partially offset by a decrease in spending on patent litigation fees. We expect our legal expenses to increase as a result of the infringement lawsuit filed against us by TDK Semiconductor Corporation in August 2001. 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. In addition, we expect selling, general and administrative expense to fluctuate as a percentage of revenues because of (1) the likelihood that indirect distribution channels, which entail the payment of commissions, will account for a larger portion of our revenues 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. WRITE OFF OF IN-PROCESS RESEARCH & DEVELOPMENT. There was no write off of in-process research & development during the three and nine months ended September 29, 2001. Write off of in-process research & development for the three and nine months ended September 30, 2000 was $0.4 million as a result of the acquisition of Krypton. GOODWILL AMORTIZATION. Goodwill amortization for the three and nine months ended September 29, 2001 was $0.0 million and $4.2 million, respectively, compared to $1.2 million and $1.2 million for the three and nine months ended September 30, 2000, respectively. During the quarter ending September 29, 2001 we recorded a charge to reduce the carrying value of goodwill (See IMPAIRMENT OF GOODWILL AND OTHER INTANGIBLE ASSETS below). IMPAIRMENT OF GOODWILL AND OTHER INTANGIBLE ASSETS. We performed an assessment of the carrying value of the Company's long-lived assets to be held and used including significant amounts of goodwill and other intangible assets recorded in connection with our acquisitions of Krypton and SNR during the year 2000. As a result, we determined that substantially all of the acquired goodwill and other intangible assets were impaired. We recorded a charge of $33.3 million to write off goodwill and a charge of $1.6 million to reduce the value of other intangible assets, based on the amount by which the carrying amount of these assets exceeded their fair market value. 12 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 $1.3 million and $4.0 million for the three and nine months ended September 29, 2001, respectively, as compared to $0.9 million and $2.5 million for the three and nine months ended September 30, 2000, respectively. The increases in the dollar amount of amortization of deferred stock compensation were due to additional deferred stock compensation for options and restricted stock issued subsequent to the first quarter of fiscal 2000. INTEREST INCOME. Interest income for the quarter ended September 29, 2001 was $0.9 million as compared to $1.2 million for the quarter ended September 30, 2000. This decrease was primarily due to lower interest rates and lower cash and short-term investments balances during the quarter ended September 29, 2001. Interest income for the nine months ended September 29, 2001 was $2.9 million as compared to $2.8 million for the nine months ended September 30, 2000. INTEREST EXPENSE. Interest expense for the three and nine months ended September 29, 2001 was $0.2 million and $0.6 million, respectively, as compared to $0.3 million and $1.0 million for the three and nine months ended September 30, 2000, respectively. The decreases in interest expense were primarily due to lower levels of debt during the recent quarter and nine month period. PROVISION (BENEFIT) FOR INCOME TAXES. Our effective tax rate, excluding the impact of non-deductible write off of in-process research and development, amortization of goodwill, impairment of goodwill and other intangible assets and deferred stock compensation, was a benefit of 40.5% in the nine months ended September 29, 2001, as compared to our effective tax expense provision rate of 36.3% in the nine months ended September 30, 2000. The current period's tax benefit rate was higher than the prior comparable period's tax expense provision rate primarily due to the current period's increased tax benefit from the estimated research and development tax credit in proportion to the amount of the current period's pre-tax loss. LIQUIDITY AND CAPITAL RESOURCES Our principal sources of liquidity as of September 29, 2001 consisted of $95.2 million in cash, cash equivalents and short-term investments in addition to our bank credit facilities. Our bank credit facilities include a revolving line of credit available for borrowings and letters of credit of up to the lesser of $5.0 million or 80% of eligible accounts receivable at the bank's prime lending rate. At September 29, 2001, a letter of credit for $0.4 million related to a building lease was outstanding under the revolving line of credit and $4.6 million was available for new borrowings based on the 80% of eligible accounts receivable limitation. We also have entered into agreements with three institutional lenders for equipment financing to purchase or lease equipment, leasehold improvements and software. At September 29, 2001, the amount outstanding under these agreements was $3.9 million. This indebtedness bears effective interest rates (including end-of-term interest payments of $1.3 million) ranging from 12.5% to 14.6% per annum, is secured by certain equipment, and is repayable over approximately the next three years. During the nine months ended September 29, 2001, cash provided by operating activities was $4.9 million as compared to cash provided by operating activities of $12.9 million during the nine months ended September 30, 2000. This reduction in cash flow was primarily due to the significant reduction in sales revenues during the period. Due to the nature of our business, we experience working capital needs in the areas of accounts receivable and inventory. Typically, we bill our customers on an open account basis with net 30 day payment terms or other specific terms and conditions that may vary from account to account as individually negotiated with customers. As of September 29, 2001, we had an accounts receivable balance of $10.7 million. If sales levels were to increase, it is likely that the level of 13 receivables would also increase. In the event that customers delay their payments to us, the levels of accounts receivable would also increase. In the area of inventory, we believe that in order to maintain an adequate supply of product for our customers, we must carry a certain level of inventory. This inventory level may vary based principally upon either orders received from customers or our forecast of demand for these products. Other considerations in determining inventory levels may include the product life cycle stage of our products, customer demands for consignment inventory arrangements, and competitive situations in the marketplace. Such considerations are balanced against risk of obsolescence or potentially excess inventory levels. The fluctuations in demand for our products caused us to establish reserves for excess inventory levels during each quarter of 2001. As of September 29, 2001, we had net inventory of $5.8 million which we deemed adequate to address these inventory considerations. Capital expenditures decreased by $9.2 million to $4.9 million for the nine months ended September 29, 2001 from $14.1 million for the nine months ended September 30, 2000. This decrease in the dollar amount of capital expenditures was primarily due to the completion of our internal test floor for existing products in fiscal 2000 and spending controls implemented during fiscal 2001. The expenditures in the recent nine months were incurred to purchase semiconductor test equipment for new products, design software and engineering tools, other computer equipment, leasehold improvements and software to support our business capabilities. We anticipate capital expenditures of approximately $6.5 million for fiscal 2001 primarily to fund additional test floor operations capabilities for wireless and optical networking products and expand engineering new product development activities. Our future capital requirements will depend on many factors, including the rate of sales growth, market acceptance of our products, the timing and extent of research and development projects and the expansion of our sales and marketing activities. We believe our existing cash balances and credit facilities are sufficient to meet our capital requirements through at least the next 12 months, although we could be required, or could elect, to seek additional funding prior to that time. We may enter into acquisitions or strategic arrangements in the future which also could require us to seek additional equity or debt financing. 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 FASB 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. The adoption of SFAS No. 133 as amended by SFAS No. 138, ACCOUNTING FOR CERTAIN INSTRUMENTS AND CERTAIN HEDGING ACTIVITIES, did not have a material impact on our financial statements since we do not utilize derivative instruments. In July 2001, the FASB issued SFAS Nos. 141 and 142, BUSINESS COMBINATIONS and GOODWILL AND OTHER INTANGIBLE ASSETS. SFAS No. 141 replaces APB No. 16 and eliminates pooling-of-interests accounting prospectively. It also provides guidance on purchase accounting related to the recognition of intangible assets and accounting for negative goodwill. SFAS No. 142 changes the accounting for goodwill from an amortization method to an impairment-only approach. Under SFAS No. 142, goodwill will be tested annually and whenever events or circumstances occur indicating that goodwill might be impaired. SFAS No. 141 and SFAS No. 142 are effective for all business combinations completed after June 30, 2001. Upon adoption of SFAS No. 142, amortization of goodwill recorded for business combinations consummated prior to July 1, 2001 will cease, and intangible assets acquired prior to July 1, 2001 that do not meet the criteria for recognition under SFAS No. 141 will be reclassified to goodwill. Companies are required to adopt SFAS No. 142 for fiscal years beginning after December 15, 2001, but early adoption is permitted. The Company will adopt SFAS No. 142 on December 30, 2001, the beginning of fiscal 2002. In connection with the adoption of SFAS No. 142, the Company will be required to perform a transitional goodwill impairment assessment. The adoption of SFAS No. 141 and SFAS No. 142 will not have a material impact on the Company's results of operations and financial position since the Company's existing balances of goodwill and other intangible assets are not significant due to impairment charges recorded during the quarter ended September 29, 2001 under SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF. 14 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. FACTORS AFFECTING OUR FUTURE OPERATING RESULTS RISKS RELATED TO OUR BUSINESS IF WE ARE UNABLE TO DEVELOP NEW AND ENHANCED PRODUCTS THAT ACHIEVE MARKET ACCEPTANCE IN A TIMELY MANNER, OUR OPERATING RESULTS AND COMPETITIVE POSITION COULD BE HARMED Our future success will depend on our ability to reduce our dependence on our DAA products by developing new integrated circuits, or ICs, and product enhancements that achieve market acceptance in a timely and cost-effective manner. The development of mixed-signal ICs is highly complex, and we occasionally have experienced delays in completing the development and introduction of new products and product enhancements. Successful product development and market acceptance of our products depend on a number of factors, including: - changing requirements of customers within the wireline, wireless and optical networking markets; - accurate prediction of market requirements; - timely completion and introduction of new designs; - timely qualification and certification of our ICs for use in our customers' products; - commercial acceptance and volume production of the products into which our ICs will be incorporated; - availability of foundry and assembly capacity; - achievement of high manufacturing yields; - quality, price, performance, power use and size of our products; - availability, quality, price and performance of competing products and technologies; - our customer service and support capabilities and responsiveness; - successful development of our relationships with existing and potential customers; and - changes in technology, industry standards or end-user preferences. We cannot provide any assurance that new products which we recently have developed or may develop in the future will achieve market acceptance. We have introduced to market or are in development of many new ICs including: - an AeroTM GSM transceiver chipset, providing a highly integrated radio communication section of a GSM wireless handset with versatile interfaces to other electronic sections of the handset; - a family of RF synthesizers, which are used to generate high frequency signals that are used in wireless communications systems to select a particular radio channel; 15 - an ISOmodem, which is a miniaturized modem that can be embedded in electronic devices with low transmission requirements, such as credit card verification devices, to provide quick network access; - a higher speed ISOmodem product to serve additional embedded modem markets demanding faster transmission requirements such as next generation set-top boxes; - a family of ProSLIC products, which provides dial tone, busy tone, caller ID and ring signal functions at the source end of the telephone addressing long-haul and short-haul applications; - a family of optical networking products, which feature highly integrated physical layer and clock circuits designed for SONET/ATM routers, multiplexers, digital cross connects and optical transceiver modules; and - a Digital Subscriber Line, or DSL, Analog Front End providing a highly integrated interface for DSL modems with legacy support for traditional analog phone line functionality. We also are actively developing other ICs. If our recently introduced or other ICs fail to achieve market acceptance, our operating results and competitive position could be adversely affected. WE DEPEND ON A LIMITED NUMBER OF CUSTOMERS FOR A SUBSTANTIAL PORTION OF OUR REVENUES, AND THE LOSS OF, OR A SIGNIFICANT REDUCTION IN ORDERS FROM, ANY KEY CUSTOMER COULD SIGNIFICANTLY REDUCE OUR REVENUES In fiscal 2000, PC-TEL accounted for 46% of our revenues. The markets for our products are dominated by a small number of potential customers. Our operating results in the foreseeable future will continue to depend on sales to a relatively small number of dominant customers, as well as the ability of these customers to sell products that use our IC products. In the future, these customers may decide not to purchase our ICs at all, purchase fewer ICs than they did in the past or alter their purchasing patterns, particularly because: - we do not have any material long-term purchase arrangements with these or any of our other customers; - substantially all of our sales to date have been made on a purchase order basis, which permits our customers to cancel, change or delay product purchase commitments with little or no notice to us and without penalty; and - some of our customers have sought or are seeking relationships with current or potential competitors which may affect our customers' purchasing decisions. Our largest customer, PC-TEL, has reported significantly fluctuating revenues in recent periods. If PC-TEL's revenues continue to decline or remain at reduced levels, we believe that our results of operations, particularly in the Wireline Products Division, will be significantly and adversely affected. While we have been the sole supplier of the direct access arrangement, or DAA, IC used in PC-TEL's soft modem DAA products, we anticipate that PC-TEL will regularly evaluate alternative sources of supply in the future in order to diversify its supplier base which would increase its negotiating leverage with us and protect its ability to secure DAA components. We have a volume purchase agreement with PC-TEL, but the agreement does not require PC-TEL to purchase any minimum number of units from us during fiscal 2001. We believe that any second source of DAA ICs for PC-TEL could have an adverse effect on the prices we are able to charge PC-TEL and the volume of DAA ICs that we sell to PC-TEL, which would negatively affect our revenues and operating results. The loss of any of our key customers, or a significant reduction in sales to any one of them, would significantly reduce our revenues and adversely affect our business. 16 WE HAVE DEPENDED ON OUR DAA FAMILY OF PRODUCTS FOR A SIGNIFICANT MAJORITY OF OUR REVENUES TO DATE, AND SUBSTANTIAL REDUCTIONS IN ORDERS FOR DAA PRODUCTS WOULD SIGNIFICANTLY REDUCE OUR REVENUES A majority of our sales to date have been derived from sales of our DAA family of ICs. This product family, in turn, is highly dependent on sales to the personal computer industry which currently faces deteriorating levels of demand. Until we are able to diversify our sales through the introduction and commercial acceptance of new products, we will continue to rely on sales of our DAA products. A continuing decline in overall demand for personal computers, reduced market acceptance of our DAA products or the introduction of products with superior price/performance characteristics by our competitors could significantly reduce our sales. In addition, substantially all of our DAA products that we have sold include technology related to one or more of our issued U.S. patents. If these patents are found to be invalid or unenforceable, our competitors could introduce competitive products that could reduce both the volume and price per unit of our products. On August 7, 2001 TDK Semiconductor Corporation filed suit against us alleging that certain of our DAA products infringe a TDK-held patent. We have filed a response denying such infringement. If our DAA products are found to infringe TDK's patent, our business operating results and financial condition could be substantially adversely affected. During the first nine months of fiscal 2001, we experienced a significant reduction in orders for our DAA family of products as a result of deteriorating demand for personal computers. Our revenues for the first nine months of fiscal 2001 declined sequentially from the nine month period ended December 31, 2000 by 39.5%, which resulted in a significant reduction in gross profits, lower gross margins and net losses for the most recent nine month period. WE MAY EXPERIENCE SIGNIFICANT PERIOD-TO-PERIOD QUARTERLY AND ANNUAL FLUCTUATIONS IN OUR REVENUES AND OPERATING RESULTS, WHICH MAY RESULT IN VOLATILITY IN OUR STOCK PRICE We may experience significant period-to-period fluctuations in our revenues and operating results in the future due to a number of factors, and any such variations may cause our stock price to fluctuate. It is likely that in some future period our operating results will be below the expectations of public market analysts or investors. If this occurs, our stock price may drop, perhaps significantly. A number of factors, in addition to those cited in other risk factors applicable to our business, may contribute to fluctuations in our revenues and operating results, including: - the timing and volume of orders received from our customers; - the rate of acceptance of our products by our customers, including the acceptance of new products we may develop for integration in the products manufactured by such customers, which we refer to as "design wins"; - the time lag between "design wins" and production orders; - the demand for, and life cycles of, the products incorporating our ICs; - the rate of adoption of mixed-signal ICs in the markets we target; - deferrals of customer orders in anticipation of new products or product enhancements from us or our competitors or other providers of ICs; - changes in product mix; and - the rate at which new markets emerge for products we are currently developing or for which our design expertise can be utilized to develop products for these new markets. 17 Due to the terrorist attacks of September 11, 2001 and subsequent world events, the end demand for consumer-oriented products such as personal computers and mobile wireless handsets may encounter a sharp and prolonged reduction in demand. The supply chain for these consumer-oriented products was facing weak consumer demand, excess inventory, low factory utilization rates, a pattern of slower upgrade cycles for personal computers, delay of next generation of mobile handset technology and overall sluggishness even before the events of September 11, 2001. The combination of the then existing business conditions and the loss of consumer confidence driven by the events of September 11, 2001 may result in a sharp deterioration in demand for our semiconductor component products which could unfavorably impact our revenues, operating results and stock price. The mobile telephone market is characterized by rapid fluctuations in demand which results in corresponding fluctuations in the demand for our wireless products that are incorporated in mobile telephones. Additionally, the rate of technology acceptance by our customers results in fluctuating demand for our products as customers are reluctant to incorporate a new IC into their products until the new IC has achieved market acceptance. However, once a new IC achieves market acceptance, demand for the new IC can quickly accelerate and demand can quickly decline for the product that the new IC replaces. DUE TO OUR LIMITED OPERATING HISTORY, WE MAY HAVE DIFFICULTY BOTH IN ACCURATELY PREDICTING OUR FUTURE SALES AND APPROPRIATELY BUDGETING FOR OUR EXPENSES We were incorporated in 1996 and did not begin generating revenues until the second quarter of 1998. As a result, we have only a short history from which to predict future revenues. This limited operating experience combined with the rapidly evolving nature of the markets in which we sell our products, as well as other factors which are beyond our control, reduce our ability to accurately forecast quarterly or annual revenues. Additionally, because most of our expenses are fixed in the short term or incurred in advance of anticipated revenues, we may not be able to decrease our expenses in a timely manner to offset any shortfall of revenues. During fiscal 2000, we expanded our staffing and increased our expense levels in anticipation of future sales growth. If our sales do not increase, we expect to incur significant losses due to our higher expense levels. WE DEPEND ON OUR CUSTOMERS TO SUPPORT OUR PRODUCTS Our products are currently used by our customers to produce modems for personal computers, mobile telephones and other wireless devices, and optical networking equipment. We rely on our customers to provide hardware, software, intellectual property indemnification and other technical support for the devices that use our products. If our customers do not provide the required functionality or if our customers do not provide satisfactory support for their products, the demand for these devices that incorporate our products may diminish. Any reduction in the demand for these devices would significantly reduce our revenues. WE RELY ON THIRD PARTIES TO MANUFACTURE AND ASSEMBLE OUR PRODUCTS AND THE FAILURE TO SUCCESSFULLY MANAGE OUR RELATIONSHIPS WITH OUR MANUFACTURERS AND ASSEMBLERS WOULD NEGATIVELY IMPACT OUR ABILITY TO SELL OUR PRODUCTS We do not have our own manufacturing facilities. Therefore, we must rely on third-party vendors to manufacture the ICs we design. We also currently rely principally on two third-party assembly contractors, Advanced Semiconductor Engineering and Amkor, to assemble and package the silicon chips provided by the wafers for use in final products. Additionally, we rely on third-party vendors for a minor portion of the testing requirements of our products prior to shipping. There are significant risks associated with relying on these third-party contractors, including: - failure by us, our customers or their end customers to qualify a selected supplier; - capacity shortages during periods of high demand; - reduced control over delivery schedules and quality; 18 - limited warranties on wafers or products supplied to us; - potential increases in prices; and - their inability to supply or support new or changing packaging technologies. We currently do not have long-term supply contracts with any of our third-party vendors, and therefore, they are not obligated to perform services or supply products to us for any specific period, or in any specific quantities, except as may be provided in a particular purchase order. Although we believe that other semiconductor foundries or assembly contractors can adequately address our needs, we expect that it would take approximately two to nine months to transition performance of these services from our current providers to new providers. Such a transition may also require a qualification process by our customers or their end customers. We generally place orders for products with some of our suppliers approximately four months prior to the anticipated delivery date, with order volumes based on our forecasts of demand from our customers. Accordingly, if we do not accurately forecast demand for our products, we may be unable to obtain adequate foundry or assembly capacity from our third-party contractors to meet our customers' delivery requirements, or we may accumulate excess inventories. On occasion, we have been unable to adequately respond to unexpected increases in customer purchase orders, and therefore, were unable to benefit from this incremental demand. None of our third-party foundry or assembly contractors have provided assurances to us that adequate capacity will be available to us within the time required to meet additional demand for our products. From our inception through the first nine months of fiscal 2001, substantially all of the silicon wafers for the products that we shipped were manufactured either by Taiwan Semiconductor Manufacturing Co. or Vanguard International Semiconductor, an affiliate of Taiwan Semiconductor Manufacturing Co. Our customers typically complete their own qualification process. If we fail to balance customer demand across semiconductor fabrications properly, we might not be able to fulfill demand for our products, which would adversely affect our operating results. Additionally, a resulting write off of unusable or excess inventories would contribute to a decline in earnings. THE SEMICONDUCTOR MANUFACTURING PROCESS IS HIGHLY COMPLEX AND, FROM TIME TO TIME, MANUFACTURING YIELDS MAY FALL BELOW OUR EXPECTATIONS WHICH COULD RESULT IN OUR INABILITY TO TIMELY SATISFY DEMAND FOR OUR PRODUCTS. The manufacture of silicon wafers for our products is a highly complex and technologically demanding process. Although we work closely with our foundries to minimize the likelihood of reduced manufacturing yields, our foundries from time to time have experienced lower than anticipated manufacturing yields. Changes in manufacturing processes or the inadvertent use of defective or contaminated materials by our foundries could result in lower than anticipated manufacturing yields or unacceptable performance deficiencies. If our foundries fail to deliver fabricated silicon wafers of satisfactory quality in a timely manner, we will be unable to meet our customers' demand for our products in a timely manner, which would adversely affect our operating results and damage our customer relationships. ANY ACQUISITIONS WE MAKE COULD DISRUPT OUR BUSINESS AND HARM OUR FINANCIAL CONDITION As part of our growth strategy, we will continue to evaluate opportunities to acquire other businesses or technologies that would complement our current offerings, expand the breadth of our markets or enhance our technical capabilities. Acquisitions that we may potentially make in the future entail a number of risks that could materially and adversely affect our business and operating results, including: - problems integrating the acquired operations, technologies or products with our existing business and products; - diversion of management's time and attention from our core business; - difficulties in retaining business relationships with suppliers and customers of the acquired company; 19 o risks associated with entering markets in which we lack prior experience; and o potential loss of key employees of the acquired company. OUR CURRENT MANUFACTURERS, ASSEMBLERS AND CUSTOMERS ARE CONCENTRATED IN THE SAME GEOGRAPHIC REGION WHICH INCREASES THE RISK THAT A NATURAL DISASTER, LABOR STRIKE, WAR OR POLITICAL UNREST COULD DISRUPT OUR OPERATIONS OR SALES Our current semiconductor manufacturers are located in the same region within Taiwan and our assembly contractors are located in the Pacific Rim region. In addition, many of our customers, particularly mobile telephone manufacturers, are located in the Pacific Rim region. The risk of earthquakes in Taiwan and the Pacific Rim region is significant due to the proximity of major earthquake fault lines in the area. We are not currently covered by insurance against business disruption caused by earthquakes as such insurance is not currently available on terms that we believe are commercially reasonable. Earthquakes, fire, flooding or other natural disasters in Taiwan or the Pacific Rim region, or political unrest, war, labor strikes or work stoppages in countries where our semiconductor manufacturers' and assemblers' facilities are located, likely would result in the disruption of our foundry or assembly capacity. Any disruption resulting from these events could cause significant delays in shipments of our products until we are able to shift our manufacturing or assembling from the affected contractor to another third-party vendor. There can be no assurance that such alternate capacity could be obtained on favorable terms, if at all. In addition, a natural disaster, labor strike, war or political unrest where our customers' facilities are located would likely reduce our sales to such customers. WE ARE SUBJECT TO INCREASED INVENTORY RISKS AND COSTS BECAUSE WE BUILD OUR PRODUCTS BASED ON FORECASTS PROVIDED BY CUSTOMERS BEFORE RECEIVING PURCHASE ORDERS FOR THE PRODUCTS In order to assure availability of our products for some of our largest customers, we start the manufacturing of our products in advance of receiving purchase orders based on forecasts provided by these customers. However, these forecasts do not represent binding purchase commitments and we do not recognize sales for these products until they are shipped to the customer. As a result, we incur inventory and manufacturing costs in advance of anticipated sales. Because demand for our products may not materialize, manufacturing based on forecasts subjects us to increased risks of high inventory carrying costs and increased obsolescence and may increase our operating costs. WE MAY NOT BE ABLE TO MAINTAIN OUR HISTORICAL GROWTH RATE Although we have experienced revenue and earnings growth in prior annual periods, we may not be able to sustain these growth rates. For the nine month period ended September 29, 2001, we reported a sequential decline of our overall revenues from the nine month period ended December 30, 2000 by 39.5% which resulted in a significant reduction in gross profits, lower gross margin percentage and a net loss for the recent nine month period. In particular, we may gain significant market share in a relatively short period of time following the introduction of a new product, resulting in revenue growth. However, incremental gains in market share for these newly introduced products may not occur. Additionally, the time lag by a customer from purchase of initial orders of our product to follow on production volume orders may extend several quarterly periods. Accordingly, you should not rely on the results of any prior quarterly or annual periods as an indication of our future operating performance. WE ARE A RELATIVELY SMALL COMPANY WITH LIMITED RESOURCES COMPARED TO SOME OF OUR CURRENT AND POTENTIAL COMPETITORS AND WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY AND INCREASE MARKET SHARE Some of our current and potential competitors have longer operating histories, significantly greater resources and name recognition and a larger base of customers than we have. As a result, these competitors may have greater credibility with our existing and potential customers. They also may be able to adopt more aggressive pricing policies and devote greater resources to the development, promotion and sale of their products than we can 20 to ours. In addition, some of our current and potential competitors have already established supplier or joint development relationships with the decision makers at our current or potential customers. These competitors may be able to leverage their existing relationships to discourage their customers from purchasing products from us or persuade them to replace our products with their products. Our competitors may also offer bundled chipset kit arrangements offering a more complete product despite the technical merits or advantages of our products. These competitors may elect not to support our products which could complicate our sales efforts. In addition, our largest competitors may restructure their operations to create separate companies that are more focused on providing the types of products we produce. For example, Rockwell's restructuring in 1998 led to the creation of Conexant which is a significant competitor. Additionally, Siemens spun off its semiconductor business in 1999 to create a more focused company named Infineon Technologies. In July 2000, Lucent Technologies spun off its microelectronics business, which included its optoelectronics components and integrated circuits division, into a separate company named Agere Systems in order to accelerate the growth of the business and alleviate strategic conflicts with Lucent's competitors. Increased competition could decrease our prices, reduce our sales, lower our margins or decrease our market share. These and other competitive pressures may prevent us from competing successfully against current or future competitors, and may materially harm our business. WE DEPEND ON OUR KEY PERSONNEL TO MANAGE OUR BUSINESS EFFECTIVELY IN A RAPIDLY CHANGING MARKET, AND IF WE ARE UNABLE TO RETAIN OUR CURRENT PERSONNEL AND HIRE ADDITIONAL PERSONNEL, OUR ABILITY TO DEVELOP AND SUCCESSFULLY MARKET OUR PRODUCTS COULD BE HARMED We believe our future success will depend in large part upon our ability to attract and retain highly skilled managerial, engineering, sales and marketing personnel. Specifically, we believe that our future success is highly dependent on Navdeep Sooch, our co-founder, Chief Executive Officer and Chairman of the Board, Daniel Artusi, our Chief Operating Officer, Jeffrey Scott, our co-founder and Vice President of Engineering, and David Welland, our co-founder and Vice President of Technology. There is currently a shortage of qualified personnel with significant experience in the design, development, manufacturing, marketing and sales of analog and mixed-signal communications ICs. In particular, there is a shortage of engineers who are familiar with the intricacies of the design and manufacturability of analog elements, and competition for such personnel is intense. Our key technical personnel represent a significant asset and serve as the source of our technological and product innovations. We may not be successful in attracting and retaining sufficient numbers of technical personnel to support our anticipated growth. The loss of any of our key employees or the inability to attract or retain qualified personnel, including engineers and sales and marketing personnel, could delay the development and introduction of, and negatively impact our ability to sell, our products. OUR RESEARCH AND DEVELOPMENT EFFORTS ARE FOCUSED ON A LIMITED NUMBER OF NEW TECHNOLOGIES AND PRODUCTS, AND ANY DELAY IN THE DEVELOPMENT, OR ABANDONMENT, OF THESE TECHNOLOGIES OR PRODUCTS BY INDUSTRY PARTICIPANTS, OR THEIR FAILURE TO ACHIEVE MARKET ACCEPTANCE, COULD COMPROMISE OUR COMPETITIVE POSITION Our ICs are used as components in communications devices in the wireline, wireless and optical networking markets. As a result, we have devoted and expect to continue to devote a large amount of resources to develop products based on new and emerging technologies and standards that will be commercially introduced in the future. In the first nine months of fiscal 2001, our research and development expense was $21.3 million, which represented 42.2% of our revenues compared to $13.3 million, or 18.1% of our revenues for the first nine months of fiscal 2000. A number of large companies in the wireline, wireless and optical networking industries are actively involved in the development of these new technologies and standards. Should any of these companies delay or abandon their efforts to develop commercially available products based on new technologies and standards, our research and development efforts with respect to these technologies and standards likely would have no appreciable value. In addition, if we do not correctly anticipate new technologies and standards, or if the products that we develop based on these new technologies and standards fail to achieve market acceptance, our competitors may be better able to address market 21 demand than would we. Furthermore, if markets for these new technologies and standards develop later than we anticipate, or do not develop at all, demand for our products that are currently in development would suffer, resulting in lower sales of these products than we currently anticipate. We have introduced to market a RF synthesizer product for use in wireless phones operating on the Global System for Mobile Communications, or GSM, standard. The RF synthesizer is also compatible with General Packet Radio Service standard, which is the emerging data communications protocol for GSM based wireless phones. We cannot be certain whether these standards will not change, thereby making our products unsuitable or impractical. In the area of optical networking, our recently introduced clock and data recovery integrated circuit operates within stringent specifications for high speed communications systems known as SONET. Changes to this standard could make our products uncompetitive or unsuitable to changing system requirements and result in our inability to sell these products. OUR PRODUCTS ARE COMPLEX AND MAY REQUIRE MODIFICATIONS TO RESOLVE UNDETECTED ERRORS WHICH COULD LEAD TO AN INCREASE IN OUR COSTS OR A REDUCTION IN OUR REVENUES Our products are complex and may contain errors when first introduced or as new versions are released. We rely primarily on our in-house testing personnel to design test operations and procedures to detect any errors prior to delivery of our products to our customers. Because our products are manufactured by third parties, should problems occur in the operation or performance of our ICs, we may experience delays in meeting key introduction dates or scheduled delivery dates to our customers. These errors also could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations and business reputation problems. THE PERFORMANCE OF OUR DIRECT ACCESS ARRANGEMENT PRODUCTS MAY BE ADVERSELY AFFECTED BY SEVERE ENVIRONMENTAL CONDITIONS THAT MAY REQUIRE MODIFICATIONS, WHICH COULD LEAD TO AN INCREASE IN OUR COSTS OR A REDUCTION IN OUR REVENUES Although our DAA products are compliant with published specifications, these established specifications might not adequately address all conditions that must be satisfied in order to operate in harsh environments. This includes environments where there are wide variations in electrical quality, telephone line quality, static electricity and operating temperatures or that may be affected by lightning or improper handling by customers and end users. Our products have had a limited period of time in the field under operation, and these environmental factors may result in unanticipated returns of our products. Any necessary modifications could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations and business reputation problems. We have a large installed base of direct access arrangement products in the field. As part of our ongoing support of this product line, we verify the performance of our products through regulatory agency qualifications, customer acceptance procedures, evaluation of end customer technical support information, and analysis of field returns. Certain customer modem implementations of our direct access arrangement products have been identified to be susceptible to a particular class of electrical surges originating from lightning strikes that are not adequately described in regulatory agency qualifications. We have provided application guidelines to our customers to enhance their implementation of the modem function to protect our devices from these lightning strike electrical surges. Damage from these electrical surges could result in product liability claims against our customers that produce these modems or against us. Our customers may seek indemnification or other compensation from us with respect to any liability that they incur. Even if our DAA product is not the source of the problem and we are not contractually liable for such indemnification, we may incur costs in an effort to maintain good relations with our customers. If we are held liable for these claims or incur other costs in order to maintain good relations, this problem could adversely affect our operating results. 22 A SUBSTANTIAL PORTION OF THE FINAL TESTING OF OUR PRODUCTS IS PERFORMED INTERNALLY BY US, WHICH INCREASES OUR FIXED COSTS In fiscal 2001 to date, substantially all of our test operations were performed in-house. A minor portion of test operations is provided by our contract manufacturers or other third parties. While we expect that performing testing in-house provides us with advantages in terms of lower per unit cost, quality control and shorter time required to bring a product to market, we may encounter difficulties and delays in maintaining or expanding our internal test capabilities. In addition, final testing of complex semiconductors requires substantial resources to acquire state-of-the-art testing equipment and hiring additional qualified personnel, which has increased our fixed costs. If demand for our products does not support the effective utilization of these employees and additional equipment, we may not realize any benefit from foregoing the use of outside vendors and utilizing internal final testing. Any decrease in the demand for our products could result in the underutilization of our testing equipment and personnel. If our internal test operations are underused or mismanaged, we may incur significant costs that could adversely affect our operating results. 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 additional 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: o increased complexity and costs of managing international operations; o protectionist laws and business practices that favor local competition in some countries; o multiple, conflicting and changing laws, regulations and tax schemes; o longer sales cycles; o greater difficulty in accounts receivable collection and longer collection periods; o high levels of distributor inventory subject to rights of return to us; and o 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 In recent periods, we have significantly increased the scope of our operations and expanded our workforce from 42 employees at January 2, 1999 to 270 employees at September 29, 2001. 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. 23 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 effective competing technologies on their own. SIGNIFICANT LITIGATION OVER INTELLECTUAL PROPERTY IN OUR INDUSTRY MAY CAUSE US TO BECOME INVOLVED IN COSTLY AND LENGTHY LITIGATION WHICH COULD SERIOUSLY HARM OUR BUSINESS In recent years, there has been significant litigation in the United States involving patents and other intellectual property rights. From time to time, we receive letters from various industry participants alleging infringement of patents or misappropriation of 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 have been involved in litigation to protect our intellectual property rights in the past and may become involved in such litigation again in the future. We are currently involved in litigation to defend allegations of infringement asserted by TDK Semiconductor Corporation. See Part II, Item 1. Legal Proceedings. In the future, we may become involved in litigation 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 intellectual property litigation also could force us to take specific actions, including: o cease selling products that use the challenged intellectual property; o 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 o redesign those products that use infringing intellectual property. On August 7, 2001, TDK Semiconductor Corporation commenced a lawsuit against the Company for alleged willful infringement by our DAA products of a TDK-held patent. TDK's complaint seeks unspecified treble damages, costs and attorneys' fees, and an injunction. On September 27, 2001, we served and filed an answer to their complaint, in which we denied infringement and asserted that their patent is invalid. This lawsuit may involve significant expense and may also divert our management's time and attention from other aspects of our business. Due to the inherent uncertainties of litigation, we are unable to predict the outcome of this matter. 24 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 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. The industry is currently experiencing a significant downturn driven by the wide and rapid deterioration in PC demand, a reduction in the expected unit sales of wireless phones from previous robust forecasts, and forecasts of excess capacity in the fiber optic networks. This downturn has resulted in a material adverse effect on our business and operating results. The severity and duration of these industry-wide trends are currently unclear and the material adverse effect on our business may continue in the future. Due to the cyclical nature of the semiconductor industry, any upturn in business 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. Except for non-contractual assurances of support for specifically identified customer accounts, none of our third-party foundry or assembly contractors have provided assurances that adequate capacity will be available to us. 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 optical networking communications markets, we face competition from a relatively large number of competitors. Across all of our product areas, we compete with Agere Systems (formerly the Lucent Microelectronics business), AMCC, Analog Devices, Broadcom, Conexant, CP Clare, Delta Integration, ESS, Fujitsu, Infineon Technologies, Legerity (formerly the Advanced Micro Devices telecom division), Maxim Integrated Products, National Semiconductor, Philips, Texas Instruments, Vitesse Semiconductor Corp, and others. We expect to face competition in the future from our current competitors, other manufacturers and designers of semiconductors, and innovative start-up semiconductor design companies. Some of our customers, such as Agere Systems, Intel, Motorola, and Texas Instruments, are also large, established semiconductor suppliers. Our sales to and support of these customers may enable them to become a source of competition to us, despite our efforts to protect our intellectual property rights. As the markets for communications products grow, we also may face competition from traditional communications device companies. These companies may enter the mixed-signal semiconductor market by introducing their own ICs or by entering into strategic relationships with or acquiring other existing providers of semiconductor products. 25 THE AVERAGE SELLING PRICES OF OUR PRODUCTS COULD DECREASE RAPIDLY WHICH MAY NEGATIVELY IMPACT OUR GROSS MARGINS AND REVENUES 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. Our customers may use their current excess inventory situation to negotiate lower prices 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 revenues 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 revenues 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 products in the customer's system as well as rigorous reliability testing. This qualification process may continue for six months or longer. However, qualification of a product by a customer does not 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 components or devices that incorporate our products. Despite these uncertainties, we devote substantial resources, including design, engineering, sales, marketing and management efforts, toward qualifying our products with customers in anticipation of sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, such failure or delay would preclude or delay sales of such product to the customer, which may impede our growth and cause our business to suffer. 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. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. Information related to quantitative and qualitative disclosures regarding market risk is set forth in Management's Discussion and Analysis of Financial Condition and Results of Operations and the risk factors under Item 2 above. Such information is incorporated by reference herein. 26 PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS On August 7, 2001, TDK Semiconductor Corporation commenced a lawsuit in the United States District Court for the Central District of California against the Company for alleged infringement by the Company of TDK's United States Patent No. 5,654,984. TDK's complaint asserts that we have infringed their '984 patent by making, using and selling in the United States certain DAA semiconductor chipsets, including our Si3035 and Si3044 products, and that the infringement was and continues to be willful. Their complaint seeks unspecified treble damages, costs and attorneys' fees, and an injunction. On September 27, 2001, we served and filed an answer to their complaint, in which we denied infringement and asserted that TDK's '984 patent is invalid. For a description of risks associated with this pending lawsuit, please see "Risk Factors--Significant litigation over intellectual property in our industry may cause the Company 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. ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS Our registration statement (Registration No. 333-94853) under the Securities Act of 1933, as amended, relating to our initial public offering of our common stock became effective on March 23, 2000. A total of 3,680,000 shares of common stock were registered. We sold a total of 3,200,000 shares of our common stock and selling stockholders sold a total of 480,000 shares to an underwriting syndicate. The managing underwriters were Morgan Stanley & Co. Incorporated, Lehman Brothers Inc., and Salomon Smith Barney Inc. The offering commenced and was completed on March 24, 2000, at a price to the public of $31.00 per share. The initial public offering resulted in net proceeds to us of $90.6 million, after deducting underwriting commissions of $6.9 million and offering expenses of $1.6 million. We used $15 million of the proceeds as part of the consideration paid in the acquisition of Krypton on August 9, 2000. Another $4.3 million was used to pay off equipment loans provided by Imperial Bank. We used another $1.0 million of the proceeds as part of the consideration paid in the acquisition of SNR on October 2, 2000. As of September 29, 2001, the remaining proceeds were invested in government securities and other short-term, investment-grade, interest bearing instruments. ITEM 3.

On the Maturity Date, as stated above, for value received, the undersigned promise(s) to pay to the order of Comerica Bank-Texas ("Bank"),at any office of the Bank in the State of Texas, Five Million Dollars (U.S.) (or that portion of it advanced by the Bank and not repaid as later provided) with interest until maturity, whether by acceleration or otherwise, or until Default, as later defined, at a per annum rate equal to the lesser of (a) the Maximum Rate, as later defined, or (b) the Stated Rate, as later defined and after that at a rate equal to the rate of interest otherwise prevailing under this Note plus three percent (3%) per annum (but in no event in excess of the Maximum Rate.) If on any day the Stated Rate shall exceed the Maximum Rate for that day, the rate of interest applicable to this Note shall be fixed at the Maximum Rate on that day and on each day thereafter until the total amount of interest accrued on the unpaid principal balance of this Note equals the total amount of interest which would have accrued if there had been no Maximum Rate. Interest rate changes will be effective for interest computation purposes as and when the Maximum Rate or the Stated Rate, as applicable, changes. Subject to the limitations hereinbelow set forth, interest shall be calculated on the basis of a 360-day year for the actual number of days the principal is outstanding. The "Stated Rate" shall mean the Bank's "prime rate" which is the annual rate of interest so designated by the Bank and which is changed by the Bank from time to time. Accrued interest on this Note shall be payable on the first day of each calendar month commencing October 1, 2001, until the Maturity Date (set forth above) when all amounts outstanding under this Note shall be due and payable in full. If the frequency of interest payments is not otherwise specified, accrued interest on this Note shall be payable monthly on the first day of each month. If any payment of principal or interest under this Note shall be payable on a day other than a day on which the Bank is open for business, this payment shall be extended to the next succeeding business day and interest shall be payable at the rate specified in this Note during this extension. A late payment charge equal to a reasonable amount not to exceed 5% of each late payment may be charged on any payment not received by the Bank within 10 calendar days after the payment due date, but acceptance of payment of this charge shall not waive any Default under this Note. The term "Maximum Rate", as used herein, shall mean at the particular time in question the maximum nonusurious rate of interest which, under applicable law, may then be charged on this Note. If such maximum rate of interest changes after the date hereof, the Maximum Rate shall be automatically increased or decreased, as the case may be, without notice to the undersigned from time to time as of the effective date of each change in such maximum rate. The principal amount payable under this Note shall be the sum of all advances made by the Bank to or at the request of the undersigned, less principal payments actually received in cash by the Bank. The books and records of the Bank shall be the best evidence of the principal amount and the unpaid interest amount owing at any time under this Note and shall be conclusive absent manifest error. No interest shall accrue under this Note until the date of the first advance made by the Bank; after that interest on all advances shall accrue and be computed on the principal balance outstanding from time to time under this Note until the same is paid in full. This Note and any other indebtedness and liabilities of any kind of the undersigned (or any of them) to the Bank, and any and all modifications, renewals or extensions of it, whether joint or several, contingent or absolute, now existing or later arising, and however evidenced and whether incurred voluntarily or involuntarily, known or unknown, or originally payable to the Bank or to a third party and subsequently acquired by Bank including, without limitation, any late charges; loan fees or charges; overdraft indebtedness; costs incurred by Bank in establishing, determining, continuing or defending the validity or priority of any security interest, pledge or other lien or in pursuing any of its rights or remedies under any loan document (or otherwise) or in connection with any proceeding involving the Bank as a result of any financial accommodation to the undersigned (or any of them); and reasonable costs and expenses of attorneys and paralegals, whether inside or outside counsel is used, and whether any suit or other action is instituted, and to court costs if suit or action is instituted, and whether any such fees, costs or expenses are incurred at the trial court level or on appeal, in bankruptcy, in administrative proceedings, in probate proceedings or otherwise (collectively "Indebtedness") are secured by and the Bank is granted a security interest in all items deposited in any account of any of the undersigned with the Bank and by all proceeds of these items (cash or otherwise), all account balances of any of the undersigned from time to time with the Bank, by all property of any of the undersigned from time to time in the possession of the Bank and by any other collateral, rights and properties described in each and every deed of trust, mortgage, security agreement, pledge, assignment and other security or collateral agreement which has been, or will at any time(s) later be, executed by any (or all) of the undersigned to or for the benefit of the Bank (collectively "Collateral"). "Collateral" shall EXCLUDE intellectual property. Intellectual property includes "Proprietary Information." "Proprietary Information" shall mean trade secrets, confidential knowledge, data, or any other proprietary information of the undersigned and each of its subsidiaries or affiliated companies. By way of illustration but not limitation. "Proprietary Information" includes (a) inventions, trade secrets, ideas, concepts, processes, formulas, data, lists, software programs, all other works of authorship, mask works, proprietary test tooling, know-how, improvements, discoveries, developments, designs, and techniques relating to the business or proposed business of the undersigned whether or not any of the foregoing is or are patentable, copyrightable, or registrable under any intellectual property laws and (b) information owned by the undersigned or licensed from third parties regarding plans for research, development, products, services, marketing and selling, business plans, budgets and unpublished financial statements, licenses, prices and costs, suppliers, customers, customer lists (except to the extent necessary for Bank to perfect or exercise its lien on the undersigned's accounts receivable), information regarding the skills and compensation of other employees of the undersigned and (c) intellectual property of third parties in the undersigned's possession. If an "Event of Default" (as defined in the Credit Agreement of even date herewith between the undersigned and the Bank, as from time to time amended, modified or restated) occurs then the Bank may at its option and without prior notice to the undersigned (or any of them), declare any or all of the Indebtedness to be immediately due and payable (notwithstanding any provisions contained in the evidence of it to the contrary), cease advancing money or extending credit to or for the benefit of the undersigned under this Note or any other agreement between the undersigned and Bank, terminate this Note as to any future liability or obligation of Bank, but without affecting Bank's rights and security interests in any Collateral or the Indebtedness , sell or liquidate all or any portion of the Collateral, set off against the Indebtedness any amounts owing by the Bank to the undersigned (or any of them), charge interest at the default rate provided in the document evidencing the relevant Indebtedness and exercise any one or more of the rights and remedies granted to the Bank by any agreement with the undersigned (or any of them) or given to it under applicable law. All payments under this Note shall be in immediately available United States funds, without setoff or counterclaim . If this Note is signed by two or more parties (whether by all as makers or by one or more as an accommodation party or otherwise), the obligations and undertakings under this Note shall be that of all and any two or more jointly and also of each severally. This Note shall bind the undersigned, and the undersigned's respective heirs, personal representatives, successors and assigns. The undersigned waive(s) presentment, demand, protest, notice of dishonor, notice of demand or intent to demand, notice of acceleration or intent to accelerate, and all other notices and agree(s) that no extension or indulgence to the undersigned (or any of them) or release, substitution or nonenforcement of any security, or release or substitution of any of the undersigned, any guarantor or any other party, whether with or without notice, shall affect the obligations of any of the undersigned. The undersigned waive(s) all defenses or right to discharge available under Section 3-605 of the Texas Uniform Commercial Code and waive(s) all other suretyship defenses or right to discharge. The undersigned agree(s) that the Bank has the right to sell, assign, or grant participations, or any interest, in any or all of the Indebtedness, and that, in connection with this right, but without limiting its ability to make other disclosures to the full extent allowable, the Bank may disclose all documents and information which the Bank now or later has relating to the undersigned or the Indebtedness. The undersigned agree(s) that the Bank may provide information relating to the Note or to the undersigned to the Bank's parent, affiliates, subsidiaries and service providers. The undersigned agree(s) to reimburse the holder or owner of this Note for any and all costs and expenses (including without limit, court costs, legal expenses and reasonable attorney fees, whether inside or outside counsel is used, whether or not suit is instituted and, if suit is instituted, whether at the trial court level, appellate level, in a bankruptcy, probate or administrative proceeding or otherwise) incurred in collecting or attempting to collect this Note or incurred in any other matter or proceeding relating to this Note. The undersigned acknowledge(s) and agree(s) that there are no contrary agreements, oral or written, establishing a term of this Note and agree(s) that the terms and conditions of this Note may not be amended, waived or modified except in a writing signed by an officer of the Bank expressly stating that the writing constitutes an amendment, waiver or modification of the terms of this Note. As used in this Note, the word "undersigned" means, individually and collectively, each maker, accommodation party, indorser and other party signing this Note in a similar capacity. If any provision of this Note is unenforceable in whole or part for any reason, the remaining provisions shall continue to be effective. Chapter 346 of the Texas Finance Code (and as the same may be incorporated by reference in other Texas statutes) shall not apply to the Indebtedness evidenced by this Note. THIS NOTE IS MADE IN THE STATE OF TEXAS AND SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES. This Note and all other documents, instruments and agreements evidencing, governing, securing, guaranteeing or otherwise relating to or executed pursuant to or in connection with this Note or the Indebtedness evidenced hereby (whether executed and delivered prior to, concurrently with or subsequent to this Note), as such documents may have been or may hereafter be amended from time to time (the "Loan Documents") are intended to be performed in accordance with, and only to the extent permitted by, all applicable usury laws. If any provision hereof or of any of the other Loan Documents or the application thereof to any person or circumstance shall, for any reason and to any extent, be invalid or unenforceable, neither the application of such provision to any other person or circumstance nor the remainder of the instrument in which such provision is contained shall be affected thereby and shall be enforced to the greatest extent permitted by law. It is expressly stipulated and agreed to be the intent of the holder hereof to at all times comply with the usury and other applicable laws now or hereafter governing the interest payable on the indebtedness evidenced by this Note. If the applicable law is ever revised, repealed or judicially interpreted so as to render usurious any amount called for under this Note or under any of the other Loan Documents, or contracted for, charged, taken, reserved or received with respect to the indebtedness evidenced by this Note, or if Bank's exercise of the option to accelerate the maturity of this Note, or if any prepayment by the undersigned or prepayment agreement results (or would, if complied with, result) in the undersigned having paid, contracted for or being charged for any interest in excess of that permitted by law, then it is the express intent of the undersigned and Bank that this Note and the other Loan Documents shall be limited to the extent necessary to prevent such result and all excess amounts theretofore collected by Bank shall be credited on the principal balance of this Note or, if fully paid, upon such other Indebtedness as shall then remaining outstanding (or, if this Note and all other Indebtedness have been paid in full, refunded to the undersigned), and the provisions of this Note and the other Loan Documents shall immediately be deemed reformed and the amounts thereafter collectable hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply with the then applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder or thereunder. All sums paid, or agreed to be paid, by the undersigned for the use, forbearance, detention, taking, charging, receiving or reserving of the indebtedness of the undersigned to Bank under this Note or arising under or pursuant to the other Loan Documents shall, to the maximum extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the rate or amount of interest on account of such indebtedness does not exceed the usury ceiling from time to time in effect and applicable to such indebtedness for so long as such indebtedness is outstanding. To the extent federal law permits Bank to contract for, charge or receive a greater amount of interest, Bank will rely on federal law instead of the Texas Finance Code for the purpose of determining the maximum Rate. 2 Additionally, to the maximum extent permitted by applicable law now or hereafter in effect, Bank may, at its option and from time to time, implement any other method of computing the Maximum Rate under the Texas Finance Code or under other applicable law, by giving notice, if required, to the undersigned as provided by applicable law now or hereafter in effect. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, it is not the intention of Bank to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration. THE UNDERSIGNED AND THE BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS NOTE OR THE INDEBTEDNESS. THIS WRITTEN LOAN AGREEMENT (AS DEFINED BY SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE) REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

SECTION 2 . FUNDING LOANS, PAYMENTS, RECOVERIES AND COLLECTIONS

2.1      FUNDING LOANS. Subject to the terms, conditions and procedures of this
         Agreement and each other Loan Document and to the satisfaction of all
         conditions precedent to the making and funding of any loan as set forth
         in any Loan Document, Bank shall make the proceeds of any such loan
         available to Borrower on the disbursement date agreed upon by Bank and
         Borrower by depositing such proceeds into an account maintained by
         Borrower with Bank or as otherwise agreed to in writing by Borrower and
         Bank.

2.2      REVOLVING LOANS. Subject to the terms and conditions of the Loan
         Documents and to the satisfaction of all conditions precedent to the
         making and funding of any loan as set forth in any Loan Document, the
         Bank agrees to make Revolving Loans to Borrower at any time and from
         time to time from the effective date hereof until (but not including)
         the Revolving Credit Maturity Date. The proceeds of Revolving Loans
         shall be used solely for working capital needs and other general
         corporate purposes of Borrower.

         Except as hereinafter provided, Borrower may request a Revolving Loan
         by submitting to Bank a request for advance by an authorized officer or
         other representative of Borrower, subject to the following: (a) each
         such request for advance shall include, without limitation, the
         proposed amount of such revolving loan and the proposed disbursement
         date, which date must be a business day; (b) each such request for
         advance shall be communicated to Bank by 2:00 p.m. (Dallas, Texas time)
         on the proposed disbursement date; (c) a request for advance, once
         communicated to Bank, shall not be revocable by Borrower; and (d) each
         request for advance, once communicated to Bank, shall constitute a
         representation, warranty and certification by Borrower as of the date
         thereof that:


                                       4


         (i) both before and after the making of such Revolving Loan, the
         obligations set forth in the Loan Documents are and shall be valid,
         binding and enforceable obligations of each Loan Party, as applicable;
         (ii) all terms and conditions precedent to the making of such Revolving
         Loan have been satisfied, and shall remain satisfied through the date
         of such Revolving Loan; (iii) the making of such Revolving Loan will
         not cause the Facility Usage to exceed the Revolving Credit Maximum
         Amount; (iv) no Default or Event of Default shall have occurred or be
         in existence, and none will exist or arise upon the making of such
         Revolving Loan; (v) the representations and warranties contained in the
         Loan Documents are true and correct in all material respects and shall
         be true and correct in all material respects as of the making of such
         Revolving Loan; and (vi) the request for advance will not violate the
         terms or conditions of any contract, indenture, agreement or other
         borrowing of any Loan Party.

         Bank may elect (but without any obligation to do so) to make a
         Revolving Loan upon the telephonic or facsimile request of Borrower,
         provided that Borrower has first executed and delivered to Bank a
         telephone notice authorization in form and content satisfactory to
         Bank. If any such Revolving Loan based upon a telephonic or facsimile
         request is made by Borrower, Bank may require Borrower to confirm said
         telephonic or facsimile request in writing by delivering to Bank, on or
         before 11:00 a.m. (Dallas, Texas time) on the next business day
         following the disbursement date of such Revolving Loan, a duly executed
         written request for advance, and all other provisions of this SECTION
         2.2 shall be applicable with respect to such Revolving Loan. In
         addition, Borrower may authorize the Bank to automatically make
         revolving loans pursuant to such other written agreements as may be
         entered into by Bank and Borrower.

         Notwithstanding anything contained in this Agreement to the contrary,
         the Facility Usage shall not at any time exceed the Revolving Credit
         Maximum Amount. If said limitations are exceeded at anytime, Borrower
         shall immediately, without demand by Bank, pay to Bank an amount not
         less than such excess, or, if Bank, in its sole discretion, shall so
         agree, Borrower shall provide Bank cash collateral in an amount not
         less than such excess, and Borrower hereby pledges and grants to Bank a
         security interest in such cash collateral so provided to Bank. Unless
         otherwise expressly provided in a Loan Document, all sums payable by
         Borrower to Bank under or pursuant to any Loan Document, whether
         principal, interest, or otherwise, shall be paid, when due, directly to
         Bank at any office of Bank located in the State of Texas in immediately
         available United States funds, and without setoff, deduction or
         counterclaim. Bank may, in its discretion, charge any and all deposit
         or other accounts (including, without limitation, any account evidenced
         by a certificate of deposit or time deposit) of Borrower maintained
         with Bank for all or any part of any Indebtedness then due and payable;
         provided, however, that such authorization shall not affect Borrower's
         obligations to pay all Indebtedness, when due, whether or not any such
         account balances maintained by Borrower with Bank are insufficient to
         pay any amounts then due.

         Borrower shall pay to Bank an annual facility fee in an amount equal to
         the product of (a) one quarter of one percent (0.25%)per annum
         multiplied by (b) the stated principal amount of the Revolving Credit
         Note. Such fee shall be computed and shall be payable on the date of
         this Agreement and on each annual anniversary date hereafter.

         The provisions of Chapter 346 of the Texas Finance Code are
         specifically declared by the parties not to be applicable to any of the
         Loan Documents or the transactions contemplated thereby.

2.3      LETTERS OF CREDIT. Subject to the terms and conditions of this
         Agreement and the other Loan Documents, the Bank shall, upon request
         from Borrower from time to time prior to the Revolving Credit Maturity
         Date, issue one or more Letters of Credit. The Letter of Credit
         Liabilities shall not exceed $2,000,000; and the Facility Usage shall
         not exceed the Revolving Credit Maximum Amount. No Letter of Credit
         shall have a stated expiration date later than the Revolving Credit
         Maturity Date, and no Letter of Credit shall provide that it will
         automatically renew upon its stated expiration date.

         Borrower shall give the Bank written notice requesting each issuance
         of a Letter of Credit hereunder not less than two business days
         prior to the requested issuance date and shall furnish such
         additional information regarding such transaction as Bank may
         request. The issuance by Bank of each Letter of Credit shall, in
         addition to the conditions precedent set forth elsewhere in this
         Agreement, be subject to the conditions precedent that (i) such Letter
         of Credit shall be in form and substance satisfactory to
         Bank, (ii) Borrower shall have executed and delivered such
         applications and other instruments and agreements relating to such
         Letter of Credit as Bank shall have requested and are not
         inconsistent with the terms of this Agreement (iii) each of the
         statements in SECTION 2.2 (d) above are true as of the date of
         issuance of such Letter of Credit with respect to issuance of such
         Letter of Credit (as opposed to making a Revolving Loan), and the
         submission of an application for issuance of a Letter of Credit
         shall constitute a representation, warranty and certification of
         Borrower to that effect, and (iv) no Letter of Credit may be issued
         if after giving effect thereto, the sum of the aggregate outstanding
         principal balance of all Revolving Loans plus the Letter of Credit
         Liabilities would exceed the Revolving Credit Maximum Amount.

                                       5


         With respect to the issuance or renewal of each Letter of Credit,
         Borrower shall pay to Bank such letter of credit fees and other
         expenses customarily charged by Bank in connection with the issuance
         or renewals of letters of credit.

         Borrower shall be irrevocably and unconditionally obligated forthwith
         to reimburse Bank for any amount paid by Bank upon any drawing under
         any Letter of Credit, without presentment, demand, protest or other
         formalities of any kind, all of which are hereby waived. Unless
         Borrower shall elect to otherwise satisfy such Reimbursement
         Obligation, such reimbursement shall, subject to satisfaction of any
         conditions provided herein for the making of Revolving Loans and to the
         Revolving Credit Maximum Amount, automatically be made by advancing to
         Borrower a Revolving Loan in the amount of such Reimbursement
         Obligation.

         In consideration of Bank's issuance of any Letter of Credit, Borrower
         shall pay to Bank a letter of credit issuance fee equal to one percent
         (1%) per annum. Such fee shall be calculated based on the term and face
         amount of such Letter of Credit and the above rate and will be payable
         quarterly in arrears.

2.4      MAXIMUM INTEREST RATE. At no time shall any Applicable Interest Rate or
         default rate in respect of any Indebtedness hereunder, exceed the
         Maximum Legal Rate. In the event that any interest is charged or
         otherwise received by Bank in excess of the Maximum Legal Rate,
         Borrower hereby acknowledges and agrees that any such excess interest
         shall be the result of an accidental and bona fide error, and any such
         excess shall be deemed to have been payment of principal, and not of
         interest, and shall be applied, first, to reduce the principal
         Indebtedness then outstanding, second, any remaining excess, if any,
         shall be applied to reduce any other Indebtedness, and third, any
         remaining excess, if any, shall be returned to Borrower.
         Notwithstanding the foregoing or anything to the contrary contained in
         this Agreement or any other Loan Document, but subject to all
         limitations contained in this Section, if at anytime any Applicable
         Interest Rate or default rate or other rate of interest applicable to
         any portion of the Indebtedness is computed on the basis of the Maximum
         Legal Rate, any subsequent reduction in the Applicable Interest Rate,
         default rate or such other rate of interest shall not reduce such
         interest rate thereafter payable below the Maximum Legal Rate until the
         aggregate amount of interest accrued equals the total amount of
         interest that would have accrued if interest had, at all times, been
         computed solely on the basis of the Applicable Interest Rate, default
         rate or such other interest rate. This Section shall control all
         agreements between the Borrower and the Bank.

2.5      RECEIPT OF PAYMENTS BY BANK. Any payment by Borrower of any of the
         Indebtedness made by mail will be deemed tendered and received by Bank
         only upon actual receipt thereof by Bank at the address designated for
         such payment, whether or not Bank has authorized payment by mail or in
         any other manner, and such payment shall not be deemed to have been
         made in a timely manner unless actually received by Bank on or before
         the date due for such payment, time being of the essence. Borrower
         expressly assumes all risks of loss or liability resulting from
         non-delivery or delay of delivery of any item of payment transmitted by
         mail or in any other manner. Acceptance by Bank of any payment in an
         amount less than the amount then due shall be deemed an acceptance on
         account only, and any failure to pay the entire amount then due shall
         constitute and continue to be an Event of Default. Prior to the
         occurrence of any Default, Borrower shall have the right to direct the
         application of any and all payments made to Bank hereunder to the
         Indebtedness evidenced by the respective notes evidencing the
         Indebtedness. Borrower waives the right to direct the application of
         any and all payments received by Bank hereunder at any time or times
         after the occurrence and during the continuance of any Default.
         Borrower further agrees that after the occurrence and during the
         continuance of any Default, or prior to the occurrence of any Default
         if Borrower has failed to direct such application, Bank shall have the
         continuing exclusive right to apply and to reapply any and all payments
         received by Bank at any time or times, whether as voluntary payments,
         proceeds from any Collateral, offsets, or otherwise, against the
         Indebtedness in such order and in such manner as Bank may, in its sole
         discretion, deem advisable, notwithstanding any entry by Bank upon any
         of its books and records. Borrower hereby expressly agrees that, to the
         extent that Bank receives any payment or benefit of or otherwise upon
         any of the Indebtedness, and such payment or benefit, or any part
         thereof, is subsequently invalidated, declared to be fraudulent or
         preferential, set aside, or required to be repaid to a trustee,
         receiver, or any other Person under any bankruptcy act, state or
         federal law, common law, equitable cause or otherwise, then to the
         extent of such payment or benefit, the Indebtedness, or part thereof,
         intended to be satisfied shall be revived and continued in full force
         and effect as if such payment or benefit had not been made or received
         by Bank, and, further, any such repayment by Bank shall be added to and
         be deemed to be additional Indebtedness.


                                       6


2.6      CONDITIONS PRECEDENT TO LOANS AND LETTERS OF CREDIT. The obligation of
         the Bank to issue any Letter of Credit, if applicable, or to make any

         following conditions precedent:

                  other documents as the Bank shall require, and all of the
                  foregoing shall be in form and content acceptable to Bank and
                  all instruments and agreements shall be in full force and
                  effect and binding and enforceable obligations of Borrower

                  as security for the Indebtedness and to accord Bank a
                  perfected security position in the Collateral, subject only to
                  Permitted Encumbrances;; (iii) a guaranty agreement from each
                  Guarantor required by Bank; (iv) such other documents or

                  validity, perfection and priority of Lien as Bank may request,
                  and Bank shall have received proof that appropriate security
                  agreements, financing statements, mortgages, deeds of trust,
                  collateral and other documents covering the Collateral shall

                  to carry out the borrowings and transactions contemplated by
                  this Agreement or any other Loan Document or incidental
                  thereto, and all other related legal matters, shall have been
                  satisfactory to and approved by Bank.

         c.       Each Loan Party shall have performed and complied with all
                  agreements and conditions contained in the Loan Documents
                  applicable to it and which are then in effect.

         d.       Each of the representations and warranties of each Loan Party
                  under any Loan Document shall be true and correct in all
                  material respects as if made on each loan disbursement date.

         e.       No Default or Event of Default shall have occurred and be

                  the financial statements most recently delivered to Bank prior
                  to the date of this Agreement; and no provision of law, any
                  order of any Governmental Authority, or any regulation, rule
                  or interpretation thereof, shall have had any Material Adverse
                  Effect on the validity or enforceability of any Loan Document.

SECTION 3. REPRESENTATIONS AND WARRANTIES

         Borrower represents and warrants, and such representations and
         warranties shall be deemed to be continuing representations and
         warranties during the entire life of this Agreement, and so long as
         Bank shall have any commitment or obligation to make any loans or issue
         any Letters of Credit, if applicable and so long as any Indebtedness
         remains unpaid and outstanding under any Loan Document, as follows:

         have been no actions commenced or threatened by any Person against
         any such property or against any Loan Party for non-compliance with any
         Environmental Law which could result in a Material Adverse Effect.

3.14     ACCURACY OF INFORMATION. All financial statements previously furnished
         to Bank have been prepared in accordance with GAAP and fairly present
         the financial condition of Borrower and, as applicable, the
         consolidated financial condition of Borrower and such other Person(s)
         as such financial statements purport to present, and the results of
         their respective operations as of the dates and for the periods covered
         thereby; and since the date(s) of said financial statements, there has
         been no material adverse change in the financial condition of Borrower
         or any other Person covered by such financial statements. Each Loan
         Party is solvent, able to pay its debts as they mature, has capital
         sufficient to carry on its business and has assets the fair market
         value of which exceed its liabilities, and no Loan Party will be
         rendered insolvent, under-capitalized or unable to pay debts generally
         as they become due by the execution or performance of any Loan Document
         to which it is a party or by which it is otherwise bound.

         are fully discharged and terminated, and thereafter, so long as any
         Indebtedness remains outstanding, it will, and, as applicable, it will
         cause each Loan Party within its control or under common control to:

         preserve and maintain such of its rights, licenses, and privileges as
         are material to the business and operations conducted by it; qualify
         and remain qualified to do business in each jurisdiction in which such
         qualification is material to its business and operations or ownership
         of its properties, continue to conduct and operate its business

         preceding calendar year; at all times maintain, preserve and protect

         accordance with GAAP; and permit Bank, or its representatives, at
         reasonable times and intervals, at Borrower's cost and expense, to
         examine its books and records and to discuss its financial matters with
         its officers, employees and independent certified public accountants;
         and permit Bank from time to time to audit Borrower's accounts,
         inventory, or other Collateral, provided that such audits will be

         demand, for customary and reasonable fees and costs incurred by Bank
         for such audits, and for each appraisal of Collateral and financial
         analysis and examination of Borrower performed from time to time by its
         agents.

4.3      REPORTING REQUIREMENTS. Borrower maintains a policy regarding insider
         trading (Statement of Company Policy--Regarding Insider Trading) and

6.2      REMEDIES UPON EVENT OF DEFAULT. Upon the occurrence and at any time

         payment of all or any portion of the Indebtedness which is payable
         on demand, at Bank's option, Bank may give notice to Borrower
         declaring all or any portion of the Indebtedness remaining unpaid
         and outstanding, whether under the notes evidencing the Indebtedness
         or otherwise, to be due and payable in full without presentation,
         demand, protest, notice of dishonor, notice of intent to accelerate,
         notice of acceleration or other notice of any kind, all of which are
         hereby expressly waived, whereupon all such Indebtedness shall
         immediately become due and payable. Furthermore, upon the occurrence
         of a Default or Event of Default and at any time during the
         existence or continuance of any Default or Event of Default, but
         without impairing or otherwise limiting the right of Bank, if
         reserved under any Loan Document, to make or withhold financial
         accommodations at its discretion, to the extent not yet disbursed,
         any commitment by Bank to make any further loans or, if applicable,
         issue any further Letters of Credit shall automatically terminate.
         The foregoing rights and remedies are in addition to any other
         rights, remedies and privileges Bank may otherwise have or which may
         be available to it, whether under this Agreement, any other Loan
         Document, by law, or otherwise.

6.3      WAIVER OF DEFAULTS. No Default or Event of Default shall be waived by
         Bank except in a written instrument specifying the scope and terms of
         such waiver and signed by an authorized officer of Bank, and such
         waiver and shall be effective only for the specific time(s) and
         purpose(s) given. No single or partial exercise of any right, power or
         privilege hereunder, or any delay in the exercise thereof, shall
         preclude other or further exercise of Bank's rights. No waiver of any
         Default or Event of Default shall extend to any other or further
         Default or Event of Default. No forbearance on the part of Bank in
         enforcing any of Bank's rights or remedies under any Loan Document
         shall constitute a waiver of any of its rights or remedies. Borrower
         expressly agrees that this Section may not be waived or modified by
         Bank by course of performance, estoppel or otherwise.

SECTION 7. MISCELLANEOUS

7.1      GOVERNING LAW. Each Loan Document shall be deemed to have been
         delivered in and shall be governed by and construed and enforced in
         accordance with the laws of the State of Texas, except to the extent
         that the UCC, other personal property law or real property law of
         another jurisdiction where Collateral is located is applicable, and
         except to the extent expressed to the contrary in any Loan Document.


                                      14



7.2      COSTS AND EXPENSES. Borrower shall pay Bank, on demand, all costs and
         expenses, including, without limitation, reasonable attorneys' fees and
         legal expenses (whether inside or outside counsel is used), incurred by
         Bank in perfecting, revising, protecting or enforcing any of its rights
         or remedies against any Loan Party or any Collateral, or otherwise
         incurred by Bank in connection with any Default or Event of Default or
         the enforcement of the Loan Documents or the Indebtedness. Following
         Bank's demand upon Borrower for the payment of any such costs and
         expenses, and until the same are paid in full, the unpaid amount of
         such costs and expenses shall constitute Indebtedness and shall bear
         interest at the highest default rate of interest provided in any Loan
         Document.

7.3      SUCCESSORS AND ASSIGNS; PARTICIPATION. This Agreement shall be binding
         upon and shall inure to the benefit of Borrower and Bank and their
         respective successors and assigns. The foregoing shall not authorize
         any assignment or transfer by Borrower of any of its respective rights,
         duties or obligations hereunder, such assignments or transfers being
         expressly prohibited. Bank, however, may freely assign, whether by
         assignment, participation or otherwise, its rights and obligations
         hereunder, and is hereby authorized to disclose to any such assignee or
         participant (or proposed assignee or participant) any financial or
         other information in its knowledge or possession regarding any Loan
         Party or the Indebtedness.

7.4      RELIANCE ON AND SURVIVAL OF VARIOUS PROVISIONS. All terms, covenants,
         agreements, representations and warranties of any Loan Party made in
         any Loan Document, or in any certificate, report, financial statement
         or other document furnished by or on behalf of any Loan Party in
         connection with any Loan Document, shall be deemed to have been relied
         upon by Bank, notwithstanding any investigation heretofore or hereafter
         made by Bank or on Bank's behalf, and those covenants and agreements of
         Borrower set forth in SECTION 4.8 hereof (together with any other
         indemnities of Borrower contained elsewhere in any Loan Document) shall
         survive the termination of this Agreement and the repayment in full of
         the Indebtedness.

7.5      COMPLETE AGREEMENT; CONFLICTS. This Agreement, the other Loan
         Documents, and any commitment letter previously issued by Bank with
         respect thereto (provided that in the event of any inconsistency or
         conflict between this Agreement and the other Loan Documents, on one
         hand, and such commitment letter, on the other hand, this Agreement and
         the Loan Documents shall control), contain the entire agreement of the
         parties thereto and supercede all prior agreements and understandings
         related to the subject matter hereof, and none of the parties shall be
         bound by anything not expressed in writing. In the event that, and to
         the extent that, any of the terms, conditions or provisions of any of
         the other Loan Documents are inconsistent with or in conflict with any
         of the terms, conditions or provisions of this Agreement, the
         applicable terms, conditions and provisions of this Agreement shall
         govern and control. Any amendments or modifications hereto shall be in
         writing signed by all parties.

7.6      COUNTERPARTS. This Agreement may be executed in any number of
         counterparts and by different parties on separate counterparts, each of
         which, when executed and delivered, shall be deemed to be an original,
         and all of which, when taken together, shall constitute but one and the
         same agreement.

7.7      WAIVER OF JURY TRIAL. BANK AND BORROWER EACH ACKNOWLEDGE THAT THE RIGHT
         TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED.
         EACH OF THEM, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO
         CONSULT, WITH COUNSEL OF THEIR CHOICE, KNOWINGLY, VOLUNTARILY AND
         INTENTIONALLY WAIVES ANY RIGHT EITHER OF THEM MAY HAVE TO A TRIAL BY
         JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF ANY LOAN DOCUMENT
         OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS OR ANY
         COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR
         ACTION OF EITHER OF THEM. THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE
         BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY BANK OR BORROWER,
         EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY EACH OF THEM.

7.8      ORAL AGREEMENTS INEFFECTIVE. THIS AGREEMENT AND THE OTHER "LOAN
         AGREEMENTS" (AS DEFINED IN SECTION 26.02(A)(2) OF THE TEXAS BUSINESS &
         COMMERCE CODE, AS AMENDED) REPRESENT THE FINAL AGREEMENT BETWEEN THE
         PARTIES, AND THIS AGREEMENT AND THE OTHER WRITTEN LOAN AGREEMENTS MAY
         NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT
         ORAL AGREEMENTS BETWEEN THE PARTIES. THERE ARE NO UNWRITTEN ORAL
         AGREEMENTS BETWEEN THE PARTIES.

[COMERICA LOGO]  SECURITY AGREEMENT
                 (ALL ASSETS)

As of September 5, 2001, for value received, the undersigned ("Debtor")
pledges, assigns and grants to Comerica Bank-Texas, a Texas banking
association ("Bank"), whose address is P. 0. Box 650282, Dallas, Texas
75265-0282, Attention: Julie Smith, Mail Code MC 6571, a continuing security
interest and lien (any pledge, assignment, security interest or other lien
arising hereunder is sometimes referred to herein as a "security interest")
in the Collateral (as defined below) to secure payment when due, whether by
stated maturity, demand, acceleration or otherwise, of all existing and
future indebtedness ("Indebtedness") to the Bank of Debtor. Indebtedness
includes without limit any and all obligations or liabilities of the Debtor to
the Bank, whether absolute or contingent, direct or indirect, voluntary or
involuntary, liquidated or unliquidated, joint or several, known or unknown,
originally payable to the Bank or to a third party and subsequently acquired
by the Bank including, without limitation, any late charges, loan fees or
charges, and overdraft indebtedness, any and all obligations or liabilities
for which the Debtor would otherwise be liable to the Bank were it not for
the invalidity or unenforceability of them by reason of any bankruptcy,
insolvency or other law, or for any other reason; any and all amendments,
modifications, renewals and/or extensions of any of the above; all costs
incurred by Bank in establishing, determining, continuing, or defending the
validity or priority of any security interest, or in pursuing its rights and
remedies under this Agreement or under any other agreement between Bank and
Debtor or in connection with any proceeding involving Bank as a result of any
financial accommodation to Borrower and/or Debtor; and all other costs of
collecting Indebtedness, including without limit attorneys' fees. Debtor
agrees to pay Bank all such costs incurred by the Bank, immediately upon
demand, and until paid all costs shall bear interest at the highest per annum
rate applicable to any of the Indebtedness, but not in excess of the maximum
rate permitted by law. Any reference in this Agreement to attorneys' fees
shall be deemed a reference to reasonable fees, costs, and expenses of both
in-house and outside counsel and paralegals, whether inside or outside
counsel is used, whether or not a suit or action is instituted, and to court
costs if a suit or action is instituted, and whether attorneys' fees or court
costs are incurred at the trial court level, on appeal, in a bankruptcy,
administrative or probate proceeding or otherwise.

Debtor further covenants, agrees, represents and warrants as follows:

1.       COLLATERAL shall mean all of the following property Debtor now or later
         owns or has an interest in, wherever located:

         (a)      all Accounts Receivable (for purposes of this Agreement,
                  "Accounts Receivable" consists of all accounts, general
                  intangibles, chattel paper (including without limit electronic
                  chattel paper and tangible chattel paper), contract rights,
                  deposit accounts, documents, instruments and rights to
                  payment evidenced by chattel paper, documents or instruments,
                  health care insurance receivables, commercial tort claims,
                  letters of credit, letter of credit rights, supporting
                  obligations, and rights to payment for money or funds advanced
                  or sold),

         (b)      all Inventory,

         (c)      all Equipment and Fixtures,

         (d)      all goods, instruments, documents, policies and certificates
                  of insurance, deposit accounts, money, investment property or
                  other property (except real property which is not a fixture)
                  which are now or later in possession or control of Bank, or
                  as to which Bank now or later controls possession by
                  documents or otherwise, and

         (e)      all additions, attachments, accessions, parts, replacements,
                  substitutions, renewals, interest, dividends, distributions,
                  rights of any kind (including but not limited to stock splits,
                  stock rights, voting and preferential rights), products, and
                  proceeds of or pertaining to the above including, without
                  limit, cash or other property which were proceeds and are
                  recovered by a bankruptcy trustee or otherwise as a
                  preferential transfer by Debtor.

         In the definition of Collateral, a reference to a type of collateral
         shall not be limited by a separate reference to a more specific or
         narrower type of that collateral. "Collateral" shall EXCLUDE
         intellectual property. Intellectual property includes "Proprietary
         Information". "Proprietary Information" shall mean trade secrets,
         confidential knowledge, data, or any other proprietary information of
         the Debtor and each of its subsidiaries or affiliated companies. By
         way of illustration but not limitation, "Proprietary Information"
         includes (a) inventions, trade secrets, ideas, concepts, processes,
         formulas, data, lists, software programs, all other works of
         authorship, mask works, proprietary test tooling, know-how,
         improvements, discoveries, developments, designs, and techniques
         relating to the business or proposed business of the Debtor whether
         or not any of the foregoing is or are patentable, copyrightable, or
         registrable under any intellectual property laws and (b) information
         owned by the Debtor or licensed from third parties regarding plans
         for research, development, products, services, marketing and selling,
         business plans, budgets and unpublished financial statements, licenses,
         prices and costs, suppliers, customers, customer lists (except to the
         extent necessary for Bank to perfect or exercise its lien on Debtor's
         Accounts Receivable), information regarding the skills and compensation
         of other employees of the Debtor and (c) intellectual property of third
         parties in Debtor's possession. Notwithstanding anything in this
         Security Agreement, the usage of the terms "rights of any kind" or
         "general intangibles" will not serve to diminish to exclusion of
         Debtor's Intellectual Property rights from the definition of
         "Collateral."

2.       WARRANTIES, COVENANTS AND AGREEMENTS. Debtor warrants, covenants and
         agrees as follows:

         2.1      Debtor shall furnish to Bank, in form and at intervals as
                  Bank may request, any information Bank may reasonably request
                  and allow Bank to examine, inspect, and copy any of Debtor's
                  books and records. Debtor shall, at the request of Bank, mark
                  its records and the Collateral to clearly indicate the
                  security interest of Bank under this Agreement.

         2.2      At the time any Collateral becomes, or is represented to be,
                  subject to a security interest in favor of Bank, Debtor shall
                  be deemed to have warranted that (a) Debtor is the lawful
                  owner of the Collateral and has the right and authority to
                  subject it to a security interest granted to Bank; (b) none of
                  the Collateral is subject to any security interest other than
                  that in favor of Bank; (c) there are no financing statements
                  on file, other than in favor of Bank; (d) no person, other
                  than Bank, has possession or control (as defined in the
                  Uniform Commercial Code) of any Collateral of such nature that
                  perfection of a security interest may be accomplished by
                  control; and (e) Debtor acquired its rights in the Collateral
                  in the ordinary course of its business.

         2.3      Debtor will keep the Collateral free at all times from all
                  claims, liens, security interests and encumbrances other than
                  those in favor of Bank. Debtor will not, without the prior
                  written consent of Bank, sell, transfer, lease or grant
                  control to any person other than Bank over, or permit to be
                  sold, transferred, leased or controlled (by a person other
                  than Bank), any or all of the Collateral, except for Inventory
                  in the ordinary course of its business and will not return any
                  Inventory to its supplier. Bank or its representatives may at
                  all reasonable times inspect the Collateral and may enter upon
                  all premises where the Collateral is kept or might be located.

         2.4      Debtor will do all acts and will execute or cause to be
                  executed all writings requested by Bank to establish,
                  maintain and continue an exclusive, perfected and first
                  security interest of Bank in the Collateral. Debtor agrees
                  that Bank has no obligation to acquire or perfect any lien on
                  or security interest in any asset(s), whether realty or
                  personalty, to secure payment of the Indebtedness, and Debtor
                  is not relying upon assets in which the Bank may have a lien
                  or security interest for payment of the Indebtedness.

         2.5      Debtor will pay within the time that they can be paid without
                  interest or penalty all taxes, assessments and similar charges
                  which at any time are or may become a lien, charge, or
                  encumbrance upon any Collateral, except to the extent
                  contested in good faith and bonded in a manner satisfactory
                  to Bank. If Debtor fails to pay any of these taxes,
                  assessments, or other charges in the time provided above, Bank
                  has the option (but not the obligation) to do so, and Debtor
                  agrees to repay all amounts so expended by Bank immediately
                  upon demand, together with interest at the highest lawful
                  default rate which could be charged by Bank on any
                  Indebtedness.

         2.6      Debtor will keep the Collateral in good condition and will
                  protect it from loss, damage, or deterioration from any cause.
                  Debtor has and will maintain at all times (a) with respect to
                  the Collateral, insurance under an "all risk" policy against
                  fire and other risks customarily insured against, and (b)
                  public liability insurance and other insurance as may be
                  required by law or reasonably required by Bank, all of which
                  insurance shall be in amount, form and content, and written by
                  companies as may be satisfactory to Bank, containing a
                  lender's loss payable endorsement acceptable to Bank. Debtor
                  will deliver to Bank immediately upon demand evidence
                  satisfactory to Bank that the required insurance has been
                  procured. If Debtor fails to maintain satisfactory insurance,
                  Bank has the option (but not the obligation) to do so and
                  Debtor agrees to repay all amounts so expended by Bank
                  immediately upon demand, together with interest at the highest
                  lawful default rate which could be charged by Bank on any
                  Indebtedness. Notwithstanding the foregoing, Borrower is under
                  no obligation to obtain foreign accounts receivable credit
                  insurance.

         2.7      Debtor will do all commercially reasonable acts and will
                  execute all writings requested by Bank to perform, enforce
                  performance of, and collect all Accounts Receivable. Debtor
                  shall neither make nor permit any modification, compromise or
                  substitution for any Account Receivable without the prior
                  written consent of Bank. Debtor shall, at Bank's request,
                  arrange for verification of Accounts Receivable directly with
                  account debtors or by other methods acceptable to Bank.


                                       1



         2.8      Debtor at all times shall be in strict compliance with all
                  applicable laws, including without limit any laws, ordinances,
                  directives, orders, statutes, or regulations an object of
                  which is to regulate or improve health, safety, or the
                  environment ("Environmental Laws").

         2.9      If Bank, acting in its sole discretion, redelivers Collateral
                  to Debtor or Debtor's designee for the purpose of (a) the
                  ultimate sale or exchange thereof; or (b) presentation,
                  collection, renewal, or registration of transfer thereof; or
                  (c) loading, unloading, storing, shipping, transshipping,
                  manufacturing, processing or otherwise dealing with it
                  preliminary to sale or exchange; such redelivery shall be in
                  trust for the benefit of Bank and shall not constitute a
                  release of Bank's security interest in it or in the proceeds
                  or products of it unless Bank specifically so agrees in
                  writing. If Debtor requests any such redelivery, Debtor will
                  deliver with such request a duly executed financing statement
                  in form and substance satisfactory to Bank. Any proceeds
                  of Collateral coming into Debtor's possession as a result of
                  any such redelivery shall be held in trust for Bank and
                  immediately delivered to Bank for application on the
                  Indebtedness. Bank may (in its sole discretion) deliver any or
                  all of the Collateral to Debtor, and such delivery by Bank
                  shall discharge Bank from all liability or responsibility for
                  such Collateral. Bank, at its option, may require delivery of
                  any Collateral to Bank at any time with such endorsements or
                  assignments of the Collateral as Bank may request.

         2.10     At any time and without notice, Bank may (a) cause any or all
                  of the Collateral to be transferred to its name or to the name
                  of its nominees, provided that any such nominee is not a
                  competitor of Debtor not normally in the business of serving
                  as a collateral trustee or related activities; (b) receive or
                  collect by legal proceedings or otherwise all dividends,
                  interest, principal payments and other sums and all other
                  distributions at any time payable or receivable on account of
                  the Collateral, and hold the same as Collateral, or apply the
                  same to the Indebtedness, the manner and distribution of the
                  application to be in the sole discretion of Bank; (c) enter
                  into any extension, subordination, reorganization, deposit,
                  merger or consolidation agreement or any other agreement
                  relating to or affecting the Collateral, and deposit or
                  surrender control of the Collateral, and accept other property
                  in exchange for the Collateral and hold or apply the property
                  or money so received pursuant to this Agreement; and (d) take
                  such actions in its own name or in Debtor's name as Bank, in
                  its sole discretion, deems necessary or appropriate to
                  establish exclusive control (as defined in the Uniform
                  Commercial Code) over any Collateral of such nature that
                  perfection of the Bank's security interest may be accomplished
                  by control.

         2.11     Bank may assign any of the Indebtedness and deliver any or all
                  of the Collateral to its assignee, who then shall have with
                  respect to Collateral so delivered all the rights and powers
                  of Bank under this Agreement, and after that Bank shall be
                  fully discharged from all liability and responsibility with
                  respect to Collateral so delivered.

         2.12     Debtor shall defend, indemnify and hold harmless Bank, its
                  employees, agents, shareholders, affiliates, officers, and
                  directors from and against any and all claims, damages, fines,
                  expenses, liabilities or causes of action of whatever kind,
                  including without limit consultant fees, legal expenses, and
                  attorneys' fees, suffered by any of them as a direct or
                  indirect result of any actual or asserted violation of any
                  law, including, without limit, Environmental Laws, or of any
                  remediation relating to any property required by any law,
                  including without limit Environmental Laws, INCLUDING ANY
                  CLAIMS, DAMAGES, FINES, EXPENSES, LIABILITIES OR CAUSES OF
                  ACTION OF WHATEVER KIND RESULTING FROM BANK'S OWN NEGLIGENCE
                  OR ARISING OUT OF ANY CLAIM OR THEORY OF STRICT LIABILITY,
                  except and to the extent (but only to the extent) caused by
                  Bank's gross negligence or wilful misconduct.

         3.1      Debtor agrees to collect and enforce payment of all Collateral
                  until Bank shall direct Debtor to the contrary. Immediately
                  upon notice to Debtor by Bank and at all times after that,
                  Debtor agrees to fully and promptly cooperate and assist Bank
                  in the collection and enforcement of all Collateral and to
                  hold in trust for Bank all payments received in connection
                  with Collateral and from the sale, lease or other disposition
                  of any Collateral, all rights by way of suretyship or guaranty
                  and all rights in the nature of a lien or security interest
                  which Debtor now or later has regarding Collateral.
                  Immediately upon and after such notice, Debtor agrees to (a)
                  endorse to Bank and immediately deliver to Bank all payments
                  received on Collateral or from the sale, lease or other
                  disposition of any Collateral or arising from any other rights
                  or interests of Debtor in the Collateral, in the form received
                  by Debtor without commingling with any other funds, and (b)
                  immediately deliver to Bank all property in Debtor's
                  possession or later coming into Debtor's possession through
                  enforcement of Debtor's rights or interests in the Collateral.
                  Debtor irrevocably authorizes Bank or any Bank employee or
                  agent to endorse the name of Debtor upon any checks or other
                  items which are received in payment for any Collateral, and to
                  do any and all things necessary in order to reduce these items
                  to money. Bank shall have no duty as to the collection or
                  protection of Collateral or the proceeds of it, or as to the
                  preservation of any related rights, beyond the use of
                  reasonable care in the custody and preservation of Collateral
                  in the possession of Bank. Debtor agrees to take all steps
                  necessary to preserve rights against prior parties with
                  respect to the Collateral. Nothing in this Section 3.1 shall
                  be deemed a consent by Bank to any sale, lease or other
                  disposition of any Collateral.

         3.2      Debtor agrees that immediately upon Bank's request, following
                  the occurrence of an Event of Default, the Indebtedness shall
                  be on a "remittance basis" as follows: Debtor shall at its
                  sole expense establish and maintain (and Bank, at Bank's
                  option may establish and maintain at Debtor's expense): (a) an
                  United States Post Office lock box (the "Lock Box"), to which
                  Bank shall have exclusive access and control. Debtor expressly
                  authorizes Bank, from time to time, to remove contents from
                  the Lock Box, for disposition in accordance with this
                  Agreement. Debtor agrees to notify all account debtors and
                  other parties obligated to Debtor that all payments made to
                  Debtor (other than payments by electronic funds transfer)
                  shall be remitted, for the credit of Debtor, to the Lock Box,
                  and Debtor shall include a like statement on all invoices; and
                  (b) a non-interest bearing deposit account with Bank which
                  shall be titled as designated by Bank (the "Cash Collateral
                  Account") to which Bank shall have exclusive access and
                  control. Debtor agrees to notify all account debtors and other
                  parties obligated to Debtor that all payments made to Debtor
                  by electronic funds transfer shall be remitted to the Cash
                  Collateral Account, and Debtor, at Bank's request, shall
                  include a like statement on all invoices. Debtor shall execute
                  all documents and authorizations as required by Bank to
                  establish and maintain the Lock Box and the Cash Collateral
                  Account.

         3.3      All items or amounts which are remitted to the Lock Box, to
                  the Cash Collateral Account, or otherwise delivered by or for
                  the benefit of Debtor to Bank on account of partial or full
                  payment of, or with respect to, any Collateral shall, at
                  Bank's option, (a) be applied to the payment of the
                  Indebtedness, whether then due or not, in such order or at
                  such time of application as Bank may determine in its sole
                  discretion, or, (b) be deposited to the Cash Collateral
                  Account. Debtor agrees that Bank shall not be liable for any
                  loss or damage which Debtor may suffer as a result of Bank's
                  processing of items or its exercise of any other rights or
                  remedies under this Agreement, including without limitation
                  indirect, special or consequential damages, loss of revenues
                  or profits, or any claim, demand or action by any third party
                  arising out of or in connection with the processing of items
                  or the exercise of any other rights or remedies under this
                  Agreement. Debtor agrees to indemnify and hold Bank harmless
                  from and against all such third party claims, demands or
                  actions, and all related expenses or liabilities, including,
                  without limitation, attorneys' fees and INCLUDING CLAIMS,
                  DAMAGES, FINES, EXPENSES, LIABILITIES OR CAUSES OF ACTION OF
                  WHATEVER KIND RESULTING FROM BANK'S OWN NEGLIGENCE OR ARISING
                  OUT OF ANY CLAIM OR THEORY OF STRICT LIABILITY except to the
                  extent (but only to the extent) caused by Bank's gross
                  negligence or willful misconduct.

4.       DEFAULTS, ENFORCEMENT AND APPLICATION OF PROCEEDS.

         4.1      Upon the occurrence of any Event of Default (as defined in the
                  Credit Agreement of even date herewith between, Debtor and
                  Bank, as from time to time amended modified or restated),
                  Debtor shall be in default under this Agreement.

4.2      Upon the occurrence of any Event of Default, Bank may at its discretion
         and without prior notice to Debtor declare any or all of the
         Indebtedness to be immediately due and payable, and shall have and
         may exercise any right or remedy available to it including, without
         limitation, any one or more of the following rights and remedies:

         (a)      Exercise all the rights and remedies upon default, in
                  foreclosure and otherwise, available to secured parties under
                  the provisions of the Uniform Commercial Code and other
                  applicable law;

         (b)      Institute legal proceedings to foreclose upon the lien and
                  security interest granted by this Agreement, to recover
                  judgment for all amounts then due and owing as Indebtedness,
                  and to collect the same out of any Collateral or the proceeds
                  of any sale of it;

         (c)      Institute legal proceedings for the sale, under the judgment
                  or decree of any court of competent jurisdiction, of any or
                  all Collateral; and/or

         (d)      Personally or by agents, attorneys, or appointment of a
                  receiver, enter upon any premises where Collateral may
                  then be located, and take possession of all or any of it
                  and/or render it unusable; and without being responsible for
                  loss or damage to such Collateral, hold, operate, sell, lease,
                  or dispose of all or any Collateral at one or more public or
                  private sales, leasings or other dispositions, at places and
                  times and on terms and conditions as Bank may deem fit,
                  without any previous demand or advertisement; and except as
                  provided in this Agreement, all notice of sale, lease or other
                  disposition, and advertisement, and other notice or demand,
                  any right or equity of redemption, and any obligation of a
                  prospective purchaser or lessee to inquire as to the power and
                  authority of Bank to sell, lease, or otherwise dispose of the
                  Collateral or as to the application by Bank of the proceeds of
                  sale or otherwise, which would otherwise be required by, or
                  available to Debtor under, applicable law are expressly waived
                  by Debtor to the fullest extent permitted.


                                        2







                  At any sale pursuant to this Section 4.2, whether under the
                  power of sale, by virtue of judicial proceedings or otherwise,
                  it shall not be necessary for Bank or a public officer under
                  order of a court to have present physical or constructive
                  possession of Collateral to be sold. The recitals contained in
                  any conveyances and receipts made and given by Bank or the
                  public officer to any purchaser at any sale made pursuant to
                  this Agreement shall, to the extent permitted by applicable
                  law, conclusively establish the truth and accuracy of the
                  matters stated (including, without limit, as to the amounts of
                  the principal of and interest on the Indebtedness, the accrual
                  and nonpayment of it and advertisement and conduct of the
                  sale); and all prerequisites to the sale shall be presumed to
                  have been satisfied and performed. Upon any sale of any
                  Collateral, the receipt of the officer making the sale under
                  judicial proceedings or of Bank shall be sufficient discharge
                  to the purchaser for the purchase money, and the purchaser
                  shall not be obligated to see to the application of the money.
                  Any sale of any Collateral under this Agreement shall be a
                  perpetual bar against Debtor with respect to that Collateral.
                  At any sale or other disposition of the Collateral pursuant to
                  this Section 4.2, Bank disclaims all warranties which would
                  otherwise be given under the Uniform Commercial Code,
                  including without limit a disclaimer of any warranty relating
                  to title, possession, quiet enjoyment or the like, and Bank
                  may communicate these disclaimers to a purchaser at such
                  disposition. This disclaimer of warranties will not render the
                  sale commercially unreasonable.

         4.3      Debtor shall at the request of Bank, notify the account
                  debtors or obligors of Bank's security interest in the
                  Collateral and direct payment of it to Bank. Bank may, itself,
                  upon the occurrence of any Event of Default so notify and
                  direct any account debtor or obligor. At the request of Bank,
                  whether or not an Event of Default shall have occurred, Debtor
                  shall immediately take such actions as the Bank shall request
                  to establish exclusive control (as defined in the Uniform
                  Commercial Code) by Bank over any Collateral which is of such
                  a nature that perfection of a security interest may be
                  accomplished by control.

         4.4      The proceeds of any sale or other disposition of Collateral
                  authorized by this Agreement shall be applied by Bank in such
                  order as the Bank, in its discretion, deems appropriate
                  including, without limitation, the following order: first upon
                  all expenses authorized by the Uniform Commercial Code and all
                  reasonable attorneys' fees and legal expenses incurred by
                  Bank; the balance of the proceeds of the sale or other
                  disposition shall be applied in the payment of the
                  Indebtedness, first to interest, then to principal, then to
                  remaining Indebtedness and the surplus, if any, shall be paid
                  over to Debtor or to such other person(s) as may be entitled
                  to it under applicable law. Debtor shall remain liable for any
                  deficiency, which it shall pay to Bank immediately upon
                  demand. Debtor agrees that Secured Party shall be under no
                  obligation to accept any noncash proceeds in connection with
                  any sale or disposition of Collateral unless failure to do so
                  would be commercially unreasonable. If Secured Party agrees in
                  its sole discretion to accept noncash proceeds (unless the
                  failure to do so would be commercially unreasonable), Secured
                  Party may ascribe any commercially reasonable value to such
                  proceeds. Without limiting the foregoing, Secured Party may
                  apply any discount factor in determining the present value of
                  proceeds to be received in the future or may elect to apply
                  proceeds to be received in the future only as and when such
                  proceeds are actually received in cash by Secured Party.

         4.5      Nothing in this Agreement is intended, nor shall it be
                  construed, to preclude Bank from pursuing any other remedy
                  provided by law or in equity for the collection of the
                  Indebtedness or for the recovery of any other sum to which
                  Bank may be entitled for the breach of this Agreement by
                  Debtor. Nothing in this Agreement shall reduce or release in
                  any way any rights or security interests of Bank contained in
                  any existing agreement between Debtor and Bank.

         4.6      No waiver of default or consent to any act by Debtor shall be
                  effective unless in writing and signed by an authorized
                  officer of Bank. No waiver of any default or forbearance on
                  the part of Bank in enforcing any of its rights under this
                  Agreement shall operate as a waiver of any other default or of
                  the same default on a future occasion or of any rights.

         4.7      Debtor (a) irrevocably appoints Bank or any agent of Bank
                  (which appointment is coupled with an interest) the true and
                  lawful attorney of Debtor (with full power of substitution) in
                  the name, place and stead of, and at the expense of, Debtor
                  and (b) authorizes Bank or any agent of Bank, in its own name,
                  at Debtor's expense, to do any of the following, as Bank, in
                  its sole discretion, deems appropriate:

                  (i)      to demand, receive, sue for, and give receipts or
                           acquittances for any moneys due or to become due on
                           any Collateral (including, without limit, to draft
                           against Collateral) and to endorse any item
                           representing any payment on or proceeds of the
                           Collateral;

                  (ii)     to execute and file in the name of and on behalf of
                           Debtor all financing statements or other filings or
                           Collateral control agreements deemed necessary or
                           desirable by Bank to evidence, perfect, or continue
                           the security interests granted in this Agreement; and

                  (iii)    to do and perform any act on behalf of Debtor
                           permitted or required under this Agreement.

         4.8      Upon the occurrence of an Event of Default, Debtor also
                  agrees, upon request of Bank, to assemble the Collateral and
                  make it available to Bank at any place designated by Bank
                  which is reasonably convenient to Bank and Debtor.

         4.9      The following shall be the basis for any finder of fact's
                  determination of the value of any Collateral which is the
                  subject matter of a disposition giving rise to a calculation
                  of any surplus or deficiency under Section 9.615 (f) of the
                  Uniform Commercial Code (a) the Collateral which is the
                  subject matter of the disposition shall be valued in an "as
                  is" condition as of the date of the disposition, without any
                  assumption or expectation that such Collateral will be
                  repaired or improved in any manner; (b) the valuation shall be
                  based upon an assumption that the transferee of such
                  Collateral desires a resale of the Collateral for cash
                  promptly (but no later than 30 days) following the
                  disposition; (c) all reasonable closing costs customarily
                  borne by the seller in commercial sales transactions relating
                  to property similar to such Collateral shall be deducted
                  including, without limitation, brokerage commissions, tax
                  prorations, attorneys' fees, whether inside or outside counsel
                  is used, and marketing costs; (d) the value of the Collateral
                  which is the subject matter of the disposition shall be
                  further discounted to account for any estimated holding costs
                  associated with maintaining such Collateral pending sale (to
                  the extent not accounted for in (c) above), and other
                  maintenance, operational and ownership expenses; and (e) any
                  expert opinion testimony given or considered in connection
                  with a determination of the value of such Collateral must be
                  given by persons having at least 5 years experience in
                  appraising property similar to the Collateral and who have
                  conducted and prepared a complete written appraisal of such
                  Collateral taking into consideration the factors set forth
                  above. The "value" of any such Collateral shall be a factor in
                  determining the amount of proceeds which would have been
                  realized in a disposition to a transferee other than a secured
                  party, a person related to a secured party or a secondary
                  obligor under Section 9-615(f) of the Uniform Commercial
                  Code.

5.       MISCELLANEOUS.

         5.1      Until Bank is advised in writing by Debtor to the contrary,
                  all notices, requests and demands required under this
                  Agreement or by law shall be given to, or made upon, Debtor at
                  the first address indicated in Section 5.15 below.

         5.2      Debtor will give Bank not less than 30 days (or such longer
                  period of time as is reasonable under the particular
                  circumstances) prior written notice of all contemplated
                  changes in Debtor's name, location, chief executive office,
                  principal place of business , and/or location of any
                  Collateral, but the giving of this notice shall not cure any
                  Event of Default caused by this change.

         5.3      Bank assumes no duty of performance or other responsibility
                  under any contracts contained within the Collateral.

         5.4      Bank has the right to sell, assign, transfer, negotiate or
                  grant participations or any interest in, any or all of the
                  Indebtedness and any related obligations, including without
                  limit this Agreement. In connection with the above, but
                  without limiting its ability to make other disclosures to the
                  full extent allowable, Bank may disclose all documents and
                  information which Bank now or later has relating to Debtor,
                  the Indebtedness or this Agreement, however obtained. Debtor
                  further agrees that Bank may provide information relating to
                  this Agreement or relating to Debtor or the Indebtedness to
                  the Bank's parent, affiliates, subsidiaries, and service
                  providers.

         5.5      In addition to Bank's other rights, any indebtedness owing
                  from Bank to Debtor can be set off and applied by Bank on any
                  Indebtedness at any time(s) either before or after maturity or
                  demand without notice to anyone. Any such action shall not
                  constitute acceptance of collateral in discharge of any
                  portion of the Indebtedness.

         5.6      Debtor, to the extent not expressly prohibited by applicable
                  law, waives any right to require the Bank to: (a) proceed
                  against any person or property; (b) give notice of the terms,
                  time and place of any public or private sale of personal
                  property security held from Borrower or Debtor or any other
                  person, or otherwise comply with the provisions of Section
                  9.611 or 9.621 of the Uniform Commercial Code; or (c) pursue
                  any other remedy in the Bank's power. Debtor waives notice of
                  acceptance of this Agreement and presentment, demand, protest,
                  notice of protest, dishonor, notice of dishonor, notice of
                  default, notice of intent to accelerate or demand payment or
                  notice of acceleration of any Indebtedness, any and all other
                  notices to which the undersigned might otherwise be entitled,
                  and diligence in collecting any Indebtedness, and agree(s)
                  that the Bank may, once or any number of times, modify the
                  terms of any Indebtedness, compromise, extend, increase,
                  accelerate, renew or forbear to enforce payment of any or all
                  Indebtedness, or permit Borrower to incur additional
                  Indebtedness, all without notice to Debtor and without
                  affecting in any manner the unconditional obligation of Debtor
                  under this Agreement. Debtor unconditionally and irrevocably
                  waives each and every defense and setoff of any nature which,
                  under principles of guaranty or otherwise, would operate to
                  impair or diminish in any way the obligation of Debtor under
                  this Agreement, and acknowledges that such waiver is by this
                  reference incorporated into each security agreement,
                  collateral assignment, pledge and/or other document from
                  Debtor now or later securing the Indebtedness, and
                  acknowledges that as of the date of this Agreement no such
                  defense or setoff exists.

         5.7      In the event that applicable law shall obligate Bank to give
                  prior notice to Debtor of any action to be taken under this
                  Agreement, Debtor agrees that a written notice given to Debtor
                  at least ten days before the date of the act shall be
                  reasonable notice of the act and, specifically, reasonable
                  notification of the time and place of any public sale or of
                  the time after which any private sale, lease, or other
                  disposition is to

                                       3





                  be made, unless a shorter notice period is reasonable under
                  the circumstances. A notice shall be deemed to be given under
                  this Agreement when delivered to Debtor or when placed in an
                  envelope addressed to Debtor and deposited, with postage
                  prepaid, in a post office or official depository under the
                  exclusive care and custody of the United States Postal Service
                  or delivered to an overnight courier. The mailing shall be by
                  overnight courier, certified, or first class mail.

         5.8      Notwithstanding any prior revocation, termination, surrender,
                  or discharge of this Agreement in whole or in part, the
                  effectiveness of this Agreement shall automatically continue
                  or be reinstated in the event that any payment received or
                  credit given by Bank in respect of the Indebtedness is
                  returned, disgorged, or rescinded under any applicable law,
                  including, without limitation, bankruptcy or insolvency laws,
                  in which case this Agreement, shall be enforceable against
                  Debtor as if the returned, disgorged, or rescinded payment or
                  credit had not been received or given by Bank, and whether or
                  not Bank relied upon this payment or credit or changed its
                  position as a consequence of it. In the event of continuation
                  or reinstatement of this Agreement, Debtor agrees upon demand
                  by Bank to execute and deliver to Bank those documents which
                  Bank determines are appropriate to further evidence (in the
                  public records or otherwise) this continuation or
                  reinstatement, although the failure of Debtor to do so shall
                  not affect in any way the reinstatement or continuation.

         5.9      This Agreement and all the rights and remedies of Bank under
                  this Agreement shall inure to the benefit of Bank's successors
                  and assigns and to any other holder who derives from Bank
                  title to or an interest in the Indebtedness or any portion of
                  it, and shall bind Debtor and the heirs, legal
                  representatives, successors, and assigns of Debtor. Nothing in
                  this Section 5.9 is deemed a consent by Bank to any assignment
                  by Debtor.

         5.10     If there is more than one Debtor, all undertakings, warranties
                  and covenants made by Debtor and all rights, powers and
                  authorities given to or conferred upon Bank are made or given
                  jointly and severally.

         5.11     Except as otherwise expressly provided in this Agreement, all
                  terms in this Agreement which are defined in the Uniform
                  Commercial Code shall have the meanings assigned to them in
                  Article 9 (or, absent definition in Article 9, in any other
                  Article) of the Uniform Commercial Code, as those meanings may
                  be amended, revised or replaced from time to time. "Uniform
                  Commercial Code" means the Texas Business and Commerce Code as
                  amended, revised or replaced from time to time.
                  Notwithstanding the foregoing, the parties intend that the
                  terms used herein which are defined in the Uniform Commercial
                  Code have, at all times, the broadest and most inclusive
                  meanings possible. Accordingly, if the Uniform Commercial Code
                  shall in the future be amended or held by a court to define
                  any term used herein more broadly or inclusively than the
                  Uniform Commercial Code in effect on the date of this
                  Agreement, then such term, as used herein, shall be given such
                  broadened meaning. If the Uniform Commercial Code shall in the
                  future be amended or held by a court to define any term used
                  herein more narrowly, or less inclusively, than the Uniform
                  Commercial Code in effect on the date of this Agreement, such
                  amendment or holding shall be disregarded in defining terms
                  used in this Agreement.

         5.12     No single or partial exercise, or delay in the exercise, of
                  any right or power under this Agreement, shall preclude other
                  or further exercise of the rights and powers under this
                  Agreement. The unenforceability of any provision of this
                  Agreement shall not affect the enforceability of the remainder
                  of this Agreement. This Agreement constitutes the entire
                  agreement of Debtor and Bank with respect to the subject
                  matter of this Agreement. No amendment or modification of this
                  Agreement shall be effective unless the same shall be in
                  writing and signed by Debtor and an authorized officer of
                  Bank. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
                  ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS,
                  WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

         5.13     To the extent that any of the Indebtedness is payable upon
                  demand, nothing contained in this Agreement shall modify the
                  terms and conditions of that Indebtedness nor shall anything
                  contained in this Agreement prevent Bank from making demand,
                  without notice and with or without reason, for immediate
                  payment of any or all of that Indebtedness at any time(s),
                  whether or not an Event of Default has occurred.

         5.14     Debtor represents and warrants that Debtor's exact name is the
                  name set forth in this Agreement. Debtor further represents
                  and warrants the following and agrees that Debtor is, and at
                  all times shall be, located in the following place :

                  liability partnership or limited liability company), and
                  Debtor is located (as determined pursuant to the Uniform
                  Commercial Code) in the state under the laws of which it was
                  organized, which is (street address, state and county or

         5.16     This Agreement shall be terminated only by the filing of a
                  termination statement in accordance with the applicable
                  provisions of the Uniform Commercial Code, but the obligations
                  contained in Section 2.12 of this Agreement shall survive

for other good and valuable consideration, Bank and Borrower agree as follows:

1.   REVOLVING LOANS. The Revolving Loans (as defined in the Credit Agreement)

           defined.

3.   FORMULA COMPLIANCE. If the limitations in paragraph 2 above are exceeded at

           original invoice or other writing evidencing such Account;

     (b)   it is not owing by an Account Debtor (as hereinafter defined) who has
           failed to pay twenty five percent (25%) or more of the aggregate
           amount of its Accounts owing to a Debtor within ninety (90) days
           after the date of the respective invoices or other writings
           evidencing such Accounts;

     (c)   it arises from the sale or lease of goods and such goods have been
           shipped or delivered to the Account Debtor under such Account; or it
           arises from services rendered and such services have been performed;

     (d)   it is evidenced by an invoice, dated not later than the date of

           other evidence of billing acceptable to Bank;

     (e)   it is not evidenced by any note, trade acceptance, draft or other
           negotiable instrument or by any chattel paper, unless such note or
           other document or instrument previously has been endorsed and
           delivered by Borrower to Bank;

     (f)   it is a valid, legally enforceable obligation of the Account Debtor
           thereunder, and is not subject to any offset, counterclaim or other
           defense on the part of such Account Debtor or to any claim on the
           part of such Account Debtor denying liability thereunder in whole or
           in part;

     (g)   it is subject to a first priority, properly perfected security
           interest in favor of Bank and is not subject to any sale of accounts,

           whatsoever other than to Bank;

     (h)   it is not owing by a subsidiary or affiliate of Borrower;

           state or political subdivision thereof, or by any department, agency,
           public body corporate or other instrumentality of any of the
           foregoing, unless all necessary steps are taken to comply with the
           Federal Assignment of Claims Act of 1940, as amended, or with any
           comparable state law, if applicable, and all other necessary steps
           are taken to perfect Bank's security interest in such Account;

     (k)   it is not owing by an Account Debtor for which Borrower has received

     or rejected inventory or services, or such other reason or factor as Bank
     deems applicable, Bank may, in its sole discretion, upon five (5) business
     days' prior written notice to Borrower, reduce or other wise modify the
     percentage of Eligible Accounts included within the Advance Formula under
     paragraph 2 above and/or reduce the dollar amount of Borrower's Eligible
