NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. BASIS OF PRESENTATION:

The condensed consolidated financial statements include the accounts of Power Integrations, Inc. (the Company), a Delaware corporation, and its wholly- owned subsidiaries. Significant inter-company accounts and transactions have been eliminated.

While the financial information furnished is unaudited, the condensed consolidated financial statements included in this report reflect all adjustments (consisting only of normal recurring adjustments) which the Company considers necessary for the fair presentation of the results of operations for the interim periods covered and of the financial condition of the Company at the date of the interim balance sheet. The results for interim periods are not necessarily indicative of the results for the entire year. The condensed consolidated financial statements should be read in conjunction with the Power Integrations, Inc. consolidated financial statements for the year ended December 31, 1999 included in its Form 10-K.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
Cash and Cash Equivalents and Short-Term Investments

The Company considers cash invested in highly liquid financial instruments with an original maturity of three months or less to be cash equivalents. Cash investments in highly liquid financial instruments with original maturities greater than three months but not longer than fifteen months are classified as short-term investments. As of September 30, 2000, the Company's short-term investments consisted of U.S. government backed securities, corporate commercial paper and other high quality commercial and municipal securities, which were classified as held to maturity and were valued using the amortized cost method which approximates market.

Revenue Recognition

Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply manufacturers and distributors. Revenues from product sales to OEMs and merchant power supply manufacturers are recognized upon shipment. Sales to distributors are made under terms allowing certain rights of return and protection against subsequent price declines on the Company's products held by the distributors. As a result of the Company's distributor agreements, the Company defers recognition of revenue and the proportionate costs of revenues derived from sales to distributors until the distributors resell the Company's products to their customers. The margin deferred as a result of this policy is reflected as "deferred income on sales to distributors" in the accompanying condensed consolidated balance sheets.

Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Segment Reporting

During 1998, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 131, "Disclosures About Segments of an Enterprise and Related Information." SFAS No.131 requires a new basis of determining reportable business segments, i.e., the management approach. This approach requires that business segment information used by management to assess performance and manage company resources be the source for information disclosure. On this basis, the Company is organized and operates as one business segment, that being the design, development, manufacture and marketing of proprietary, high-voltage, analog circuits for use in the AC to DC power conversion market.

New Accounting Standards

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 establishes accounting and reporting standards for derivative instruments, hedging activities, and exposure definition. SFAS No. 133 requires companies to recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. SFAS No. 133 is effective for all fiscal quarters of fiscal years beginning after June 15, 2000. Because the Company does not currently hold any derivative instruments and does not currently engage in hedging activities, management believes that the application of SFAS No. 133 will not have a material impact on its consolidated results of operations and financial position.

In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements." SAB 101 provides guidance on applying generally accepted accounting principles to revenue recognition issues in financial statements. The Company will adopt SAB 101 as required in the fourth quarter of 2000 and does not expect such adoption to have a material impact on its consolidated results of operations and financial position.

5. EARNINGS PER SHARE:

Earnings per share are calculated in accordance with SFAS No. 128 "Earnings per Share." SFAS No. 128 requires companies to compute earnings per share under two different methods (basic and diluted). Basic earnings per share are calculated by dividing net income by the weighted average shares of common stock outstanding during the period. Diluted earnings per share are calculated by dividing net income by the weighted average shares of outstanding common stock and common stock equivalents during the period. Common stock equivalents included in the diluted calculation consist of dilutive shares issuable upon the exercise of outstanding common stock options and shares issuable under the employee stock purchase plan using the treasury stock method.

The following table sets forth the calculation of basic and diluted earnings per share (in thousands, except per share amounts):

                                                                     Three Months Ended          Nine Months Ended

6. PROVISION FOR INCOME TAXES:

Income tax expense for the nine-month periods ended September 30, 2000 and 1999 includes a provision for Federal, state and foreign taxes based on the annual estimated effective tax rate applicable to the Company and its subsidiaries for the year. The difference between the statutory rate and the Company's effective tax rate for the nine months ended September 30, 2000 is primarily due to the beneficial impact of international sales, research and development credits and Federal tax exempt investments.

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

This Management's Discussion and Analysis of Financial Condition and Results of Operations includes a number of forward-looking statements which reflect our current views with respect to future events and financial performance. In this report, the words "anticipates," "believes," "expects," "future," "intends," and similar expressions identify forward-looking statements. These forward-looking statements are subject to certain risks and uncertainties, including those discussed in the "Factors That May Affect Future Results of Operations" and elsewhere in this report, that could cause actual results to differ materially from historical or anticipated results. We caution you not to place undue reliance on these forward-looking statements, which speak only as of the date of this report.

The following management's discussion and analysis of financial condition and results of operations should be read in conjunction with management's discussion and analysis of financial condition and results of operations included in our Form 10-K for the year ended December 31, 1999.

Overview

We design, develop, manufacture and market proprietary, high-voltage, analog integrated circuits, or ICs, for use primarily in AC to DC power conversion markets. We have targeted high-volume power supply markets, including the cellular telephone, personal computer, cable and direct broadcast satellite and various consumer and industrial electronics markets. Our initial focus is on those markets that are sensitive to size, portability, energy efficiency and time-to-market. We believe our patented TOPSwitch ICs, introduced in 1994, are the first highly integrated power conversion ICs to achieve widespread market acceptance. We introduced an enhanced family of ICs, TOPSwitch-II, in April 1997. In September 1998, we announced the TinySwitch family of integrated circuits for power supplies used in a broad range of electronic products. TinySwitch ICs - designed to reduce energy leakage by incorporating our new EcoSmart technology - enable a new class of light, compact, energy-efficient power supplies. In March 2000, we introduced the TOPSwitch-FX family of products, which also incorporates our EcoSmart technology to help engineers meet the growing need for environmentally friendly power solutions. We believe this new family of ICs gives power supply design engineers the ability to cost- effectively integrate additional functionality into the power supplies they design.

Comparison of the Three and Nine Months Ended September 30, 2000 and 1999

Net revenues. Net revenues consist of revenues from product sales, which are calculated net of returns and allowances, plus license fees and royalties paid by licensees of our technology. Net revenues for the quarter ended September 30, 2000 were $27.9 million compared to $30.1 million for the third quarter of 1999, a decrease of $2.3 million, or 7.6%. Net revenues for the nine months ended September 30, 2000 were $84.9 million compared to $73.9 million for the comparable period of 1999, an increase of $10.9 million, or 14.8%

Net revenues from product sales represented $27.4 million and $29.8 million in the third quarter of 2000 and 1999, respectively. Net revenues from product sales represented $83.6 million and $72.9 million in the nine months ended September 30, 2000 and 1999, respectively. The decrease in net revenues from product sales for the three months ended September 30, 2000 was attributable primarily to less than expected demand in power supplies for cellular phones, one of our major markets, which was down approximately 48% from the same quarter in the prior year. Our other major market, PC stand-by, increased by approximately 14% and the "other markets" category, including the set top decoder box market, increased approximately 20% compared to the quarter ended September 30, 1999. Sales in our two major markets were down approximately 9% and 1%, respectively, while sales in the "other markets" category increased approximately 43% for the nine months ended September 30, 2000 compared to the same period of the prior year. In total, sales of our TOPSwitch and TinySwitch products accounted for 97.5% and 97.8% of net revenues from product sales for the three months ended September 30, 2000 and 1999, respectively, and 97.7% and 96.7% for the nine months ended September 30, 2000 and 1999, respectively.

International sales were $22.5 million in the third quarter of 2000 compared to $23.5 million for the same period in 1999, a decrease of $1 million, or 4.3%, which represented 80.7% of net revenues compared to 78.1% in the comparable period of 1999. International sales were $69.8 million for the nine months ended September 30, 2000 compared to $57.8 million for the same period in 1999, an increase of $12 million, or 20.8%, and represented 82.3%

11

of net revenues compared to 78.2% in the comparable period of 1999. Although the power supplies using our products are designed and distributed worldwide, most of these power supplies are manufactured in Asia. As a result, sales to this region were 61.7% and 61.9% of our product sales for the three months ended September 30, 2000 and 1999, respectively, and 63.2% and 61.8% of our product sales for the nine months ended September 30, 2000 and 1999, respectively. We expect international sales to continue to account for a large portion of our net revenues.

Direct sales for the third quarter of 2000 were divided 50.1% to distributors and 49.9% to original equipment manufacturers, or OEMs, and power supply merchants, compared to 39% to distributors and 61% to OEMs and power supply merchants for the same quarter in 1999. For the nine months ended September 30, 2000, direct sales were divided 49.5% to distributors and 50.5% to OEMs and power supply merchants, compared to 41.5% to distributors and 58.5% to OEMs and power supply merchants for the same period in 1999. For the quarter ended September 30, 2000, sales to one customer accounted for 21.3% of net revenues, and for the quarter ended September 30, 1999, that same customer accounted for 14.1% of net revenues, with a second customer, accounting for 11.3% of net revenues. For the nine months ended September 30, 2000, sales to one customer accounted for 21.1% of net revenues, and for the nine months ended September 30, 1999, that same customer accounted for 15.9% of net revenues, with a second customer accounting for 11.1% of net revenues.

The exact dollar amounts and percentages of sales to end customers are difficult to ascertain because most of those sales occur through distributors or indirectly through sales to merchant power supply manufacturers, which in turn sell power supplies to OEMs. However, we estimate that direct and indirect sales to Motorola, who is our largest end user, accounted for approximately 7.8% and 23.4% of net revenues for the quarters ended September 30, 2000 and 1999, respectively, and approximately 11.3% and 21.5% of net revenues for the nine months ended September 30, 2000 and 1999, respectively. Direct sales to Motorola were approximately 4% and 6.7% of net revenues for the quarters ended September 30, 2000 and 1999, respectively, and approximately 5.8% and 9.6% of net revenues for the nine months ended September 30, 2000 and 1999, respectively.

Cost of revenues; Gross profit. Gross profit is equal to net revenues less cost of revenues. Our cost of revenues consists primarily of costs associated with the purchase of wafers, the assembly and packaging of our products, and internal labor and overhead associated with the testing of both wafers and packaged components. Gross profit for the third quarter of 2000 was $14.6 million, or 52.3% of net revenues, compared to $17.5 million, or 58% of net revenues for the same period in 1999. Gross profit for the nine months ended September 30, 2000 was $44.3 million, or 52.2% of net revenues, compared to $41.3 million, or 55.9% of net revenues for the same period in 1999. Gross profit in 1999 benefited from a one-time credit from one of our suppliers in the amount of $1.2 million recorded in the third quarter. This credit resulted in gross profit improvement of 4.0% for the quarter and 1.6% for the nine months ended September 30, 1999. The additional decrease in gross profit percentage for the three months and nine months ended September 30, 2000 was primarily due to the adverse impact of increased customer pricing pressure, partially offset by reduced material pricing.

Research and development expenses. Research and development expenses consist primarily of employee-related expenses, expensed material and facility costs associated with the development of new processes and new products. We also expense prototype wafers and mask sets related to new products as research and development costs until new products are released to production. Research and development expenses for the third quarter of 2000 were $3.1 million compared to $2.8 million for the same period in 1999, an increase of $271,000, or 9.6%, which represented 11.1% and 9.4% of our net revenues in each period, respectively. Research and development expenses for the first nine months of 2000 were $9.6 million compared to $7.7 million for the same period in 1999, an increase of $1.9 million, or 24.5%, which represented 11.3% and 10.4% of net revenues in each period, respectively. The increase for the three months and nine months ended September 30, 2000 was primarily due to increased salaries and other costs related to the hiring of additional engineering personnel, outside consulting fees and expensed prototype materials caused by the transition of foundry manufacturing processes, and bringing newly developed products into manufacturing. We expect research and development expenses to continue to increase in absolute dollars but to fluctuate as a percentage of our net revenues.

Sales and marketing expenses. Sales and marketing expenses consist primarily of employee-related expenses, commissions to sales representatives and facilities expenses, including expenses associated with our regional sales and support offices. Sales and marketing expenses for the second quarter of 2000 were $3.1 million compared to $2.9 million for the same period in 1999, an increase of $246,000, or 8.5%, which represented 11.3% and 9.6% of our net revenues in each period, respectively. Sales and marketing expenses for the first nine months of 2000 were

12

$10 million compared to $8.1 million for the same period in 1999, an increase of $1.9 million, or 23.3%, which represented 11.7% and 11% of our net revenues in each period, respectively. The increase for the three months and nine months ended September 30, 2000 primarily resulted from the addition of personnel to support increased sales and increase the availability of field application engineers. We expect sales and marketing expenses to continue to increase in absolute dollars but to fluctuate as a percentage of our net revenues.

General and administrative expenses. General and administrative expenses consist primarily of employee-related expenses for administration, finance, human resources and general management, as well as consulting, outside services, legal and auditing expenses. For the quarters ended September 30, 2000 and 1999, general and administrative expenses were $1.7 million and $4.3 million, respectively, which represented 6.2% and 14.3% of our net revenues in each period. For the nine months ended September 30, 2000 and 1999, general and administrative expenses were $5.2 million and $7.1 million, respectively, which represented 6.1% and 9.6% of our net revenues in each period. The decrease in spending was primarily attributable to a reduction in professional and legal expenses, which were expended for patent infringement litigation during 1999. We expect general and administrative expenses to continue to increase in absolute dollars, but to fluctuate as a percentage of our net revenues.

Other income, net. Other income, net, for the third quarter of 2000 increased by $191,000 over the same period in 1999, and for the nine months ended September 30, 2000, increased by $625,000 over the same period in 1999. The increase for the three and nine month periods ended September 30, 2000 was due primarily to additional interest income from an increase in cash equivalents and short-term investments in 2000.

Provision for income taxes. Provision for income taxes represents Federal, state and foreign taxes. The provision for income taxes was $2.2 million for the third quarter of 2000 compared to $1.2 million for the same period in 1999. The provision for income taxes was $6.5 million for the first nine months of 2000 compared to $3 million for the same period in 1999. Our estimated effective tax rate for 2000 is 30% compared to 15% used in the same periods for 1999. The difference between the statutory rate and our effective tax rate for 2000 is primarily due to the beneficial impact of international sales, research and development credits and Federal tax exempt investments.

Liquidity and Capital Resources

At September 30, 2000, we had approximately $60.7 million in cash, cash equivalents and short-term investments. In addition, under a revolving line of credit agreement with Union Bank of California, we can borrow up to $10 million. A portion of the credit line is used to cover advances for commercial letters of credit and standby letters of credit, which we provide to Matsushita and OKI prior to the shipment of wafers by the foundries to us. The balance of this credit line is unused and available. The line of credit agreement contains financial covenants and requires that we maintain profitability on a quarterly basis and not pay or declare dividends without the bank's prior consent. In previous years we have financed a significant portion of our machinery and equipment through capital equipment leases. There was no additional equipment financing during the nine months ended September 30, 2000.

As of September 30, 2000, we had working capital, defined as current assets less current liabilities, of approximately $85.3 million, which was an increase of approximately $14.2 million over December 31, 1999. Our operating activities generated cash of $6 million and $19.6 million in the nine months ended September 30, 2000 and 1999, respectively. Cash generated in the first nine months of 2000 was principally the result of net income in the amount of $15.2 million, depreciation and amortization, and an increase in accrued liabilities, partially offset by an increase in inventory and decrease in accounts payable. Cash generated in the first nine months of 1999 was principally the result of net income of $17 million, a decrease in inventory and increases in accounts payable and accrued liabilities, offset by increases in accounts receivable and deferred taxes.

Our investing activities were a net transfer from short-term investments to cash and cash equivalents of $13.2 million in the nine months ended September 30, 2000 and a net transfer from cash and cash equivalents to short-term investments of $14.6 million in the nine months ended September 30, 1999. Purchases of property and equipment were $10.8 million and $4.1 million in the nine months ended September 30, 2000 and 1999, respectively. The increase in property and equipment purchases was due primarily to capital expenditures for tenant improvements on a new facility.

We believe that cash generated from operations, together with existing sources of liquidity, will satisfy our projected working capital and other cash requirements for at least the next 12 months.

New Accounting Standards

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 establishes accounting and reporting standards for derivative instruments, hedging activities, and exposure definition. SFAS No. 133 requires companies to recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. SFAS No. 133 is effective for all fiscal quarters of fiscal years beginning after June 15, 2000. Because we do not currently hold any derivative instruments and do not currently engage in hedging activities, we believe that the application of SFAS No. 133 will not have a material impact on our consolidated results of operations and financial position.

In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements." SAB 101 provides guidance on applying generally accepted accounting principles to revenue recognition issues in financial statements. We will adopt SAB 101 as required in the fourth quarter of 2000 and do not expect such adoption to have a material impact on our consolidated results of operations and financial position.

Factors That May Affect Future Results of Operations

In addition to the other information in this report, the following factors should be considered carefully in evaluating our business before purchasing shares of our stock.

Our quarterly operating results are volatile and difficult to predict. If we fail to meet the expectations of public market analysts or investors, the market price of our common stock may decrease significantly. Our net revenues and operating results have varied significantly in the past, are difficult to forecast, are subject to numerous factors both within and outside of our control, and may fluctuate significantly in the future. As a result, our quarterly operating results will likely fall below the expectations of public market analysts or investors. If that occurs, the price of our stock may decline.

Some of the factors that could affect our operating results include the following:

. the volume and timing of orders received from customers;
. the volume and timing of orders placed by us with our foundries;
. changes in product mix including the impact of new product introduction on existing products;
. our ability to develop and bring to market new products and technologies on a timely basis;
. the timing of investments in research and development and sales and marketing;
. cyclical semiconductor industry conditions; and
. fluctuations in exchange rates, particularly the exchange rates between the U.S. dollar and the Japanese yen.

Our quarterly results may be subject to seasonality. Historically, our revenues have been strongest in our third and fourth quarters, due to what we believe are seasonal factors attributed to the high volume consumer markets for the end products into which our ICs are sold. Our revenues have then followed a pattern of being sequentially linear or somewhat down in the first and second quarters of the next year.

We do not have long-term contracts with any of our customers and if they fail to place, or if they cancel or reschedule orders for our products, our operating results and business may suffer. Our business is characterized by short-term customer orders and shipment schedules. The ordering patterns of some of our existing large customers have been unpredictable in the past and we expect that customer-ordering patterns will continue to be unpredictable in the future. Not only does the volume of units ordered by particular customers vary substantially from period to period, but also purchase orders received from particular customers often vary substantially from early oral estimates provided by those customers for planning purposes. In addition, customer orders can be canceled or rescheduled

14

without penalty to them. In the past we have experienced customer cancellations of substantial orders for reasons beyond our control, and significant cancellations could occur again at any time.

We depend on Motorola for a significant portion of our net revenues and if we lose Motorola as a customer, our operating results will suffer. For the nine months ended September 30, 2000, direct sales to Motorola accounted for approximately 6% of our net revenues. Indirect sales, through power supply merchants, which incorporate our ICs into the products they produce for Motorola, accounted for another approximately 5% of our net revenues. For the nine months ended September 30, 1999, direct sales and indirect sales to Motorola accounted for approximately 9% and 12% of our net revenues, respectively. We expect that our operating results will depend, in part, on our direct and indirect sales to Motorola for the foreseeable future. In addition, if Motorola continues to shift from higher end to lower end cellular phones that incorporate older technology chargers which do not use our ICs, our direct and indirect sales to Motorola may decline, which may hurt our operating results.

Intense competition in the high-voltage power supply industry may lead to a decrease in the average selling price and reduced sales volume of our products, which may harm our business. The high-voltage power supply industry is intensely competitive and characterized by significant price erosion. Our products face competition from alternative technologies, including traditional linear transformers and discrete switcher power supplies. If the price of competing products decreases significantly, the cost effectiveness of our products will be adversely affected. If power requirements for applications in which our products are currently utilized, including battery chargers for cellular telephones, drop below current power levels, these older alternative technologies can be used more cost effectively than our TOPSwitch-based switchers.

We cannot assure you that our products will continue to compete favorably or that we will be successful in the face of increasing competition from new products and enhancements introduced by existing competitors or new companies entering this market. We believe our failure to compete successfully in the high-voltage power supply business, including our ability to introduce new products with higher average selling prices, would materially harm our operating results.

If demand for our products declines in the cellular phone battery charger and desktop personal computer stand-by markets, our net revenues will decrease. Applications of our products in the cellular phone battery chargers and desktop personal computer, or PC, stand-by markets have and should continue to account for a significant portion of our net revenues. For the three-month periods ended September 30, 2000 and 1999, net revenues from the cellular phone battery charger market were approximately $6.1 million and $11.8 million, respectively, a decrease of $5.7 million or approximately 48%. For the comparable nine-month periods, net revenues from this market were approximately $24.9 million in 2000 and $27.4 in 1999, a decrease of $2.5 million or approximately 9%. Net revenues from the desktop personal computer stand-by markets increased approximately $700,000 or 14% during the three months ended September 30, 2000 compared to the same period in 1999, and were unchanged at approximately $14.5 million for the nine month periods ended September 30, 2000 and 1999. We expect that our net revenues and operating results will continue to be substantially dependent upon these markets for the foreseeable future. The cellular phone and desktop PC markets can be highly cyclical and have been subject to significant economic downturns at various times. Any significant downturn in these markets could cause our net revenues to decline and the price of our stock to fall. In addition, technological advances in these markets may reduce demand for our products.

Because the sales cycle for our products can be lengthy, we may incur substantial expenses before we generate significant revenues, if any. Our products are generally incorporated into a customer's products at the design stage. However, customer decisions to use our products, commonly referred to as design wins, which can often require us to expend significant research and development and sales and marketing resources without any assurance of success, often precede volume sales, if any, by a year or more. The value of any design win will largely depend upon the commercial success of the customer's product. We cannot assure you that we will continue to achieve design wins or that any design win will result in future revenues. If a customer decides at the design stage not to incorporate our products into its product, we may not have another opportunity for a design win with respect to that product for many months or years.

15

Our products must meet exacting specifications, and undetected defects and failures may occur which could cause customers to return or stop buying our products. Our customers generally establish demanding specifications for quality, performance and reliability that our products must meet. ICs as complex as those we sell often encounter development delays and may contain undetected defects or failures when first introduced or after commencement of commercial shipments. We have from time to time in the past experienced product quality, performance or reliability problems. If defects and failures occur in our products, we could experience lost revenue, increased costs, including warranty expense and costs associated with customer support, delays in or cancellations or rescheduling of orders or shipments and product returns or discounts, any of which would harm our operating results.

We depend on third-party suppliers to provide us with wafers for our products and if they fail to provide us sufficient wafers, our business will suffer. We have supply arrangements for the production of wafers with Matsushita and OKI. Although certain aspects of our relationships with Matsushita and OKI are contractual, many important aspects of these relationships depend on their continued cooperation and, in many instances, their course of conduct deviates from the literal provisions of the contracts. We cannot assure you that we will continue to work successfully with Matsushita or OKI in the future, that they will continue to provide us with sufficient capacity at their foundries to meet our needs, or that either of them will not seek an early termination of its wafer supply agreement with us. We estimate that it would take 9 to 12 months from the time we identified an alternate manufacturing source before that source could produce wafers with acceptable manufacturing yields in sufficient quantities to meet our needs.

Although we provide Matsushita and OKI with rolling forecasts of our production requirements, their ability to produce wafers for us is limited by the available capacities of the foundries in which these wafers are manufactured. An increased need for capacity to meet internal demands or demands of other customers could cause Matsushita and OKI to reduce capacity available to us. Matsushita and OKI may also require us to pay amounts in excess of contracted or anticipated amounts for wafer deliveries or require us to make other concessions in order to acquire the wafer supply necessary to meet our customers' requirements. Any of these concessions could harm our business.

If our third-party suppliers and independent subcontractors do not produce our wafers and assemble our finished products at acceptable yields, our net revenues may decline. We depend on Matsushita and OKI to produce wafers, and independent subcontractors to assemble finished products, at acceptable yields and to deliver them to us in a timely manner. The failure of Matsushita or OKI to supply us wafers at acceptable yields could prevent us from selling our products to our customers and would likely cause a decline in our net revenues. In addition, our IC assembly process requires our manufacturers to use a high- voltage molding compound available from only one vendor, which is difficult to process. This compound and its required processes, together with the other non- standard materials and processes needed to assemble our products, require a more exacting level of process control than normally required for standard packages. Unavailability of the sole source compound or problems with the assembly process can materially adversely affect yields and cost to manufacture. We cannot assure you that acceptable yields will be maintainable in the future.

Matsushita has licenses to our technology, which it may use to our detriment. Our ability to take advantage of the potentially large Japanese market for our products is largely dependent on Matsushita and its ability to promote and deliver our products. Pursuant to our agreement with Matsushita, Matsushita has the right to manufacture and sell products using our technology to Japanese companies worldwide and to subsidiaries of Japanese companies located in Asia. Although we receive royalties on Matsushita's sales, these royalties are substantially lower than the gross profit we would receive on direct sales. We cannot assure you that Matsushita will not use the technology rights we have granted it to develop or market competing products following any termination of its relationship with us or after termination of Matsushita's royalty obligation to us.

Our international sales activities subject us to substantial risks. Sales to customers outside of the United States account for a large portion of our net revenues. These sales involve a number of risks to us, including:

. potential insolvency of international distributors and representatives;
. reduced protection for intellectual property rights in some countries;

16

. the impact of recessionary environments in economies outside the United States;
. tariffs and other trade barriers and restrictions; and
. the burdens of complying with a variety of foreign laws.

Our failure to adequately address these risks could reduce our international sales, which would materially adversely affect our operating results. Furthermore, because substantially all of our foreign sales are denominated in U.S. dollars, increases in the value of the dollar increase the price in local currencies of our products in foreign markets and make our products relatively more expensive and less price competitive than competitors' products that are priced in local currencies.

If our efforts to enhance existing products and introduce new products are not successful, we may not be able to generate demand for our products. Our success depends in significant part upon our ability to develop new ICs for high-voltage power conversion for existing and new markets, to introduce these products in a timely manner and to have these products selected for design into products of leading manufacturers. We have accelerated some of our new product introduction schedules and these schedules are subject to the risks and uncertainties that typically accompany accelerated development and delivery of complex technologies to the market place, including product development delays and defects. If we fail to develop and sell new products in a timely manner, our net revenues could decline.

We cannot be sure that we will be able to adjust to changing market demands as quickly and cost-effectively as necessary to compete successfully. Furthermore, we cannot assure you that we will be able to introduce new products in a timely and cost-effective manner or in sufficient quantities to meet customer demand or that these products will achieve market acceptance. Our, or our customers' failure to develop and introduce new products successfully and in a timely manner would harm our business and may cause the price of our common stock to fall. In addition, customers may defer or return orders for existing products in response to the introduction of new products. Although we maintain reserves against returns, we cannot assure you that these reserves will be adequate.

If our products do not penetrate additional markets, our business will not grow as we predict. We believe that our future success depends in part upon our ability to penetrate additional markets for our products. We cannot assure you that we will be able to overcome the marketing or technological challenges necessary to do so. To the extent that a competitor penetrates additional markets before we do, or takes market share from us in our existing markets, our net revenues and financial condition could be materially adversely affected.

If we are unable to adequately protect or enforce our intellectual property rights, we could lose market share, incur costly litigation expenses or lose valuable assets. Our success depends upon our ability to protect our intellectual property, including patents, trade secrets, and know-how, and to continue our technological innovation. We cannot assure you that the steps we have taken to protect our intellectual property will be adequate to prevent misappropriation or that others will not develop competitive technologies or products. From time to time we have received, and we may receive in the future, communications alleging possible infringement of patents or other intellectual property rights of others. Litigation, which could result in substantial cost to us, may be necessary to enforce our patents or other intellectual property rights or to defend us against claimed infringement of the rights of others. The failure to obtain necessary licenses or other rights or litigation arising out of infringement claims could cause us to lose market share and harm our business.

Moreover, the laws of some foreign countries in which our technology is or may in the future be licensed may not protect our intellectual property rights to the same extent as the laws of the United States, thus increasing the possibility of infringement of our intellectual property.

We must attract and retain qualified personnel to be successful and competition for qualified personnel is intense in our market. Our success depends to a significant extent upon the continued service of our executive officers and other key management and technical personnel. The competition for these employees is intense, particularly in Silicon Valley. The planned move to our new headquarters in South San Jose has caused some loss of

17

personnel, and could cause additional loss of personnel because of an unfavorable change in the commute for some of our employees. The loss of the services of one or more of our engineers, executive officers or other key personnel or our inability to recruit replacements for these individuals or to otherwise attract, retain and motivate qualified personnel could harm our business. We have neither long-term employment contracts with, nor key person life insurance policies on, any of our employees.

Our recent growth has strained our resources and if we fail to successfully manage this growth, we may lose customers. We have experienced a period of rapid growth and expansion, which has placed, and continues to place, a significant strain on our resources. Relationships with our customers generally require significant engineering support. A significant increase in the number of customers using our technology will increase the strain on our resources, particularly our engineers. These strains may result in delays or difficulties in our research and development process, which could impede our ability to develop future generations of our products and to remain competitive. In addition, any future periods of rapid growth or expansion could be expected to place a significant strain on our limited managerial, financial and engineering resources.

We have adopted anti-takeover measures, which may make it more difficult for a third party to acquire us. We have adopted a preferred stock purchase rights plan that is intended to guard against hostile takeover tactics. The adoption of this plan was not in response to any proposal to acquire us, and the board is not aware of any such effort. Our board of directors has the authority to issue up to 3,000,000 shares of preferred stock and to determine the price, rights, preferences and privileges of those shares without any further vote or action by the stockholders. The rights of the holders of common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of shares of preferred stock, while potentially providing flexibility in connection with possible acquisitions and for other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock. We have no present intention to issue shares of preferred stock.

The future trading price of our common stock could be subject to wide fluctuations in response to a variety of factors. The price of our common stock has been, and is likely to be, volatile. Factors including future announcements concerning us or our competitors, quarterly variations in operating results, announcements of technological innovations, the introduction of new products or changes in our product pricing policies or those of our competitors, proprietary rights or other litigation, changes in earnings estimates by analysts and other factors could cause the market price of our common stock to fluctuate substantially. In addition, stock prices for many technology companies fluctuate widely for reasons, which may be unrelated to operating results. These fluctuations, as well as general economic, market and political conditions, may harm the market price of our common stock.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS.

There has not been a material change in our exposure to interest rate and foreign currency risks since the date of our 1999 Form 10-K.

Interest Rate Risk. Our exposure to market risk for changes in interest rates relate primarily to our investment portfolio. We do not use derivative financial instruments in our investment portfolio. We invest in high-credit quality issuers and, by policy, limit the amount of credit exposure to any one issuer. As stated in our policy, we ensure the safety and preservation of our invested principal funds by limiting default risk, market risk and reinvestment risk. We mitigate default risk by investing in safe and high-credit quality securities and by constantly positioning our portfolio to respond appropriately to a significant reduction in a credit rating of any investment issuer, guarantor or depository. The portfolio includes only marketable securities with active secondary or resale markets to ensure portfolio liquidity.

The table below presents principal amounts and related weighted average interest rates for our investment portfolio at September 30, 2000. All investments mature, by policy, in 15 months or less.

order is placed.

3.3 Most Favored Customer. The prices of Wafers purchased by PI under this Agreement shall be the lowest price charged by MEC/MEI to any foundry customers for similar products being purchased in similar volumes under similar terms and conditions as this Agreement and during the term hereof. Should MEC/MEI sell or agree to sell the same or similar products at lower price under more favorable terms and conditions or at the same price under more favorable terms and conditions, MEC/MEI will notify PI in writing within thirty (30) days of the effective date of such sale or agreement and shall automatically extend to PI as of such effective date the benefit of such more favorable prices or terms and conditions.

3.4 Leadtimes. After the bring-up of the baseline process:

(a) MEC/MEI will complete mask sets for any PI Product within seven
(7) working days after the receipt by MEC/MEI of a final database tape for such PI Product. PI will bear all the costs of mask tooling.

(b) MEC/MEI will ship to PI prototype Wafers of any PI Products within forty (40) working days after availability of mask sets for such PI Product. MEC/MEI and PI will negotiate in good faith the possibility of making available to PI fast-turn lots for certain prototype Wafers. PI will pay for those prototype wafers.

(c) MEC/MEI will ship the first (1st) shipment of the Wafers ordered by PI for that month no later than forty (40) working days after the start of the production as per PI's purchase order for such PI Products, unless PI's purchase order specifies a later delivery date. The rest of the ordered Wafers for that month will be shipped so that PI receives all such Wafers, in equal weekly quantities to the extent practicably possible, within forty (40) working days after the first (1st) shipment. MEC/MEI shall use its reasonable and best efforts to improve actual leadtime for the production of Wafers.

(d) In the event the production of new Products (including Updates of the Products) requires more complicated manufacturing process to MEC, including the case, but not limited to, where the increase of the number of masks used for such production, or the manufacturing processes of the Products are transferred from the present Fab to another qualified Fab, the leadtime stated in Section 3.4(c) may be changed according to such different conditions if both parties agree to such change.

3.5 Order Forecasts. Once PI Product enters volume production, MEC/MEI shall provide PI sufficient information concerning wafer lot sizes and cycle times to enable PI to plan its purchase orders. PI agrees to place monthly orders/releases for tested Wafers with MEC/MEI. PI shall issue purchase orders and rolling six (6) month forecasts on a monthly basis as follows:

(a) PI shall deliver an initial binding purchase order covering four
(4) months of deliveries of tested Wafers and a nonbinding forecast[s] for same for the following two (2) months.

(b) In order to allow MEC the smooth production of the Wafers, by the twenty-fifth (25th) day of each month during the term of this Agreement, PI shall deliver a purchase order and updated forecast, specifying (i) its firm, noncancellable order for Wafer starts for the next four (4) months ahead; the first month of which is specified by product, and the next three months of which are forecast by product, against which the numbers of Wafers (but not necessarily the product mix) stated in PI's actual


orders shall be the same, and (ii) the quantities of Wafers to be ordered by PI for the months five (5) and six (6) months ahead, against which PI's actual orders will be within the range of plus or minus thirty percent (30%).

3.6 Acceptance. All Wafers delivered to PI by MEC/MEI hereunder shall be subject to the inspection and acceptance criteria being used at the time of this Agreement or the ones to be mutually agreed upon by the parties hereto during the term of this Agreement, which basically consists of PCM test and visual inspection criteria. In the event any lot or Wafers is found to fail such applicable inspection and acceptance criteria, PI shall have the right to reject such lot or Wafers by giving notice of such effect within sixty (60) days after PI receives them and return them at MEC/MEI's cost and risk after obtaining a return authorization number from MEC/MEI in writing. PI shall provide MEC/MEI with a report specifying the reason for such rejection. MEC/MEI shall provide either a refund, or a replacement lot of the Wafers within forty-five (45) days after the receipt thereof pursuant to the mutual consent of the parties. All rejected products may be subject to inspection by MEC/MEI to confirm that they are defective. Any product not rejected by PI within sixty (60) days after receipt by PI shall be deemed accepted.

3.7 Warranty. EXCEPT AS EXPRESSLY SET FORTH IN SECTION 3.7 HEREOF, MEC/MEI MAKES AND PI RECEIVES NO WARRANTIES OR CONDITIONS ON THE WAFERS, EXPRESS OR IMPLIED, STATUTORY OR OTHERWISE, AND MEC/MEI SPECIFICALLY DISCLAIMS ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. MEC/MEI AGREES TO KEEP RECORDS FOR THREE (3) YEARS OF EACH PROCESSED LOT MANUFACTURED AND SUMMARIES OF PROCESS MONITORS FOR ONE (1) YEAR FOR WARRANTY TRACEABILITY. THE FOREGOING IS PI'S SOLE REMEDY FOR BREACH OF WARRANTY BY MEC/MEI WITH RESPECT TO ANY WAFERS SUPPLIED BY MEC/MEI. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, IN THE EVENT ANY CUSTOMER OF PI CLAIMS ANY INCONVENIENCE IN ANY PRODUCTS RESULTING FROM MEC'S DIFFUSION OF WAFERS AND PI DECIDES TO DEAL WITH SUCH INCONVENIENCE, MEC SHALL GIVE NECESSARY SUPPORT TO PI UPON REQUEST.

3.8 Terms and Conditions. To the extent not inconsistent with the provisions of this Agreement, the terms and conditions of PI's standard purchase order shall apply to MEC/MEI's provision of goods and services to PI under this Agreement.

3.9 Payment Terms. Payment for the Wafers shall be by telephonic transfer within thirty (30) days after bill of lading date and secured by a standby letter of credit to be opened at a first class bank selected by PI and reasonably acceptable to MEC/MEI. MEC/MEI agrees to negotiate terms or alternate forms of payment as proposed by PI.

3.10 Title and Transportation. All shipments to PI will be made F.O.B. point of shipment. Title and risk of loss and damage will pass to PI upon delivery of Products to the carrier at the shipping point in good conditions. Unless written instructions from PI specify the method of shipment, MEC/MEI will use the least expensive means of shipment which will permit on time delivery of the products to PI.

ARTICLE IV

EXPORT CONTROL

4.1 Technical Data. Each party hereby assures the others that it will not, without prior authorization, if required, of the Office of Export Administration, U.S. Department of Commerce, 14th and Constitution Ave., N.W., Washington, D.C. 20230, export or re-export (as defined in Section 779.1(b)-(c) of the Export Administration Regulations - "Regulations" - and any amendments thereto) the technical data covered thereby. PI shall inform MEC in writing of the technical data restricted under such Regulations as well as its restricted country group upon PI's disclosure or provision of technical information.

4.2 Other Restrictions. In exercising its rights under this Agreement, each party agrees to comply strictly and fully with all export controls imposed on Wafers, by any country or organization or nations within whose jurisdiction each party operates or does business. Each party agrees not to export or permit export of Wafers or any related technical data or complying with the export control laws in the relevant jurisdiction.

4.3 Each party shall not export the Product to any country designated as "Countries against which the sanctions should be taken" by certain resolutions of the Security Council of the United Nations regarding the sanctions against certain countries, as long as such resolutions remain valid and effective. For purposes of this Agreement, any re-export in violation of such resolutions by a customer of either MEC or PI will not be considered to be an export in violation of such resolutions by MEC or PI, as the case may be, so long as MEC or PI, as the case may be, did not knowingly participate in such re-export.

4.4 During and after the term of this Agreement, to the extent the same practically is within its control, each party shall not sell, lease or otherwise dispose of, directly or indirectly, any Product to customers whom such party knows intend to make use of the Product for Military Purposes (defined hereinbelow). For the purpose of this Agreement, "Military Purposes" means the design, development, manufacture or use of any weapons, including without limitation nuclear weapons, biological weapons, chemical weapons and missiles.

4.5 In the event either party violates the provisions of this Article IV, the non-violating party shall have the right to require reasonable written assurances from the violating party that such violation, whether or not past incidents of violation can be cured, will not continue in the future, and if the violating party does not deliver such assurances to the non-violating party promptly after its request, the non-violating party may suspend the performance of its obligations under this Agreement until such time as it receives such assurances, without any prejudice to the rights and remedies which the non- violating party may have under this Agreement. In the event that such assurance is not delivered to the non-violating party within three (3) months after request, the non-violating party shall the right to terminate forthwith, without any prejudice to the rights and remedies which it may have hereunder, this Agreement, by giving a written notice to the violating party.

(b) Notwithstanding any other provision of the Agreement, PI may without the prior consent of MEC assign all of its rights under this Agreement to a purchaser of all or substantially all of PI's stock or assets or to a third party participating in a merger or other corporate reorganization in which PI is a constituent corporation. Within 180 days after such assignment, if the assignee is (i) a competitor of MEC, and (ii) of comparable size to MEC or larger, then either MEC or PI's assignee may elect to have this Agreement be deemed to have expired and to have the provisions of Section 8.4(b) take effect 180 days after written notice to the other party of such election.

(c) As a condition of any assignment of this Agreement or any of the rights granted hereunder, any successor shall expressly assume in writing the performance of all terms and conditions of this Agreement to be performed by the assigning party including such party's obligations hereunder with respect to the protection of Confidential Information. The successor's name shall thereafter automatically be substituted for the name of the assigning party in this Agreement.

9.5 No Rights to Marks, Etc. Except as provided in Section 9.2 above, nothing contained in this Agreement shall confer any rights to use in advertising, publicity, or otherwise, any trademarks, trade names, or any contraction, abbreviation or simulation thereof, of either party, provided such restriction shall not apply to identification numbers and descriptions of devices and software which are the subject matter of this Agreement.

9.6 No Joint Venture. Nothing contained in this Agreement shall be construed as:

(a) creating any partnership, joint venture or other similar relationship between PI and MEC; or

(b) obligating either party to commercially produce or to continue to commercially produce, any solid state device of any type whatsoever, or any parts or components thereof (except as provided in the Foundry Agreement).

9.7 Force Majeure. Anything contained in this Agreement to the contrary notwithstanding, the obligations of the parties hereto shall be subject to all laws, both present and future, of any government having jurisdiction over the parties hereto, and to orders, regulations, directions or requests of any such government, or any department, agency or corporation thereof, and to war, acts of public enemies, strikes or other labor disturbances, fires, floods, earthquakes, acts of God, or causes of like or different kind beyond the control of the parties and the parties hereto shall be excused from any failure to perform any obligation hereunder to the extent such failure is caused by any such law, order, regulation, direction, request or contingency, for the period such cause endures. Notwithstanding the foregoing, in the event any such cause delays either party's performance of any of its material obligations under this Agreement,

Confidential

20

the other party may suspend its performance hereunder for the period such delay continues and if any such cause renders impossible or delays for a period of more than six months either Party's performance of any of its material obligations under this Agreement, the other party may terminate this Agreement pursuant to Section 8.3, as if a material default had occurred hereunder and shall have the rights and remedies specified in Article VIII. The party whose performance is delayed on account of any such cause shall promptly notify the other party, and shall exert its best efforts to recommence performance as soon as possible.

9.8 Entire Agreement. This Agreement and the Foundry Agreement to be entered into along with this Agreement set forth the entire agreement and understanding between the parties as to the subject matter hereof and thereof and supersede all prior discussions, negotiations and agreements, written, oral or implied, between them in respect of the subject matter of this Agreement. None of the parties shall be bound by any conditions, definitions, warranties, understandings or representations with respect to such subject matter other than as expressly provided herein or therein or as duly set forth on or subsequent to the date hereof or thereof in writing and signed by a proper and duly authorized officer or representative of the party to be bound thereby.

9.9 Remedies. Upon the breach by any party to this Agreement of any provision of this Agreement or the Foundry Agreement, the non-breaching party shall have the right to pursue all available remedies at law or in equity it may elect, in order to obtain the benefits to have been provided pursuant to this Agreement, or to obtain adequate recourse or compensation in the event the same are not so provided.

9.10 Absence of Waivers. Failure or delay on the part of a party hereto to enforce any of the provisions of this Agreement or any rights with respect thereto, or to exercise any election provided for herein shall in no way be considered to be a waiver of such provisions, rights or elections or in any way affect the validity of this Agreement. Failure or delay on the part of a party to exercise any of the said provisions, rights or elections shall not preclude or prejudice such party from later enforcing or exercising the same or any other provisions, rights or elections which it may have under this Agreement.

9.11 Notices. All notices shall be given in writing either by personal delivery to the party to whom notice is given, or by a commercial overnight courier service, or by registered or certified mail, return receipt requested. The date upon which any such notice is so personally delivered, the date of confirmation of courier delivery, or if the notice is given by registered or certified mail the date of the return receipt, shall be deemed to be the date of such notice, irrespective of the date appearing therein.

--------------------------------------------------------------------------------

DATE:    JULY 10, 2000

     FOR VALUE RECEIVED, on JULY 1, 2002  the undersigned ("Debtor") promises to
                            -------------

pay to the order of UNION BANK OF CALIFORNIA, N.A. ("Bank"), as indicated below, the principal sum of TEN MILLION AND NO/100 Dollars ($10,000,000.00), or so much thereof as is disbursed, together with interest on the balance of such principal from time to time outstanding, at a per annum rate or rates and at the times set forth below. Any letters of credit issued and outstanding in connection with this note shall result in reduction of the amount available to Debtor.

1. INTEREST PAYMENTS. Debtor shall pay interest on the 1st day of each Month commencing August 1, 2000. Should interest not be paid when due, it shall become a part of the principal and thereafter bear interest as herein provided. All computations of interest under this note shall be made on the basis of a year of 360 days, for actual days elapsed.

a. BASE INTEREST RATE. At Debtor's option, amounts outstanding hereunder in minimum amounts of at least $100,000.00 shall bear interest at a rate, based on an index selected by Debtor, which is 1.500% per annum in excess of Bank's LIBOR Rate for the Interest Period selected by Debtor, acceptable to Bank.

No Base Interest Rate may be changed, altered or otherwise modified until the expiration of the Interest Period selected by Debtor. The exercise of interest rate options by Debtor shall be as recorded in Bank's records, which records shall be prima facie evidence of the amount borrowed under either interest option and the interest rate; provided, however, that failure of Bank to make any such notation in its records shall not discharge Debtor from its obligations to repay in full with interest all amounts borrowed. In no event shall any Interest Period extend beyond the maturity date of this note.

To exercise this option, Debtor may, from time to time with respect to principal outstanding on which a Base Interest Rate is not accruing, and on the expiration of any Interest Period with respect to principal outstanding on which a Base Interest Rate has been accruing, select an index offered by Bank for a Base Interest Rate Loan and an Interest Period by telephoning an authorized lending officer of Bank located at the banking office identified below prior to 1 0:00 a.m., Pacific time, on any Business Day and advising that officer of the selected index, the Interest Period and the Origination Date selected (which Origination Date, for a Base Interest Rate Loan based on the LIBOR Rate, shall follow the date of such selection by no more than two (2) Business Days).

Bank will mail a written confirmation of the terms of the selection to Debtor promptly after the selection is made. Failure to send such confirmation shall not affect Bank's rights to collect interest at the rate selected. If, on the date of the selection, the index selected is unavailable for any reason, the selection shall be void. Bank reserves the right to fund the principal from any source of funds notwithstanding any Base Interest Rate selected by Debtor.

b. VARIABLE INTEREST RATE. All principal outstanding hereunder which is not bearing interest at a Base Interest Rate shall bear interest at a rate per annum equal to the Reference Rate, which rate shall vary as and when the Reference Rate changes.

If any interest rate defined in this note ceases to be available from Bank for any reason, then said interest rate shall be replaced by the rate then offered by Bank, which, in the sole discretion of Bank, most closely approximates the unavailable rate.

At any time prior to the maturity of this note, subject to the provisions of paragraph 4, below, of this note, Debtor may borrow, repay and reborrow hereon so long as the total outstanding at any one time does not exceed the principal amount of this note. Debtor shall pay all amounts due under this note in lawful money of the United States at Bank's SAN JOSE-TEAM 1 Office, or such other office as may be designated by Bank, from time to time.

2. LATE PAYMENTS. If any payment required by the terms of this note shall remain unpaid ten days after same is due, at the option of Bank, Debtor shall pay a fee of $100 to Bank.

3. INTEREST RATE FOLLOWING DEFAULT. In the event of default, at the option of Bank, and, to the extent permitted by law, interest shall be payable on the outstanding principal under this note at a per annum rate equal to FIVE AND NO/100 percent ( 5.000% ) in excess of the interest rate specified in paragraph
1.b, above, calculated from the date of default until all amounts payable under this note are paid in full.

4. PREPAYMENT.

a. Amounts outstanding under this note bearing interest at a rate based on the Reference Rate may be prepaid in whole or in part at any time, without penalty or premium. Debtor may prepay amounts outstanding under this note bearing interest at a Base Interest Rate in whole or in part provided Debtor has given Bank not less than five (5) Business Days prior written notice of Debtor's intention to make such prepayment and pays to Bank the prepayment fee due as a result. The prepayment fee shall also be paid, if Bank, for any other reason, including acceleration or foreclosure, receives all or any portion of principal bearing interest at a Base Interest Rate prior to its scheduled payment date. The prepayment fee shall be an amount equal to the present value of the product of: (i) the difference (but not less than zero) between (a) the Base Interest Rate applicable to the principal amount which is being prepaid, and (b) the return which Bank could obtain if it used the amount of such prepayment of principal to purchase at bid price regularly quoted securities issued by the United States having a maturity date most closely coinciding with the relevant Base Rate Maturity Date and such securities were held by Bank until the relevant Base Rate Maturity Date ("Yield Rate"), (ii) a fraction, the numerator of which is the number of days in the period between the date of prepayment and the relevant Base Rate Maturity Date and the denominator of which is 360; and (iii) the amount of the principal so prepaid (except in the event that principal payments are required and have been made as scheduled under the terms of the Base Interest Rate Loan being prepaid, then an amount equal to the lesser of (A) the amount prepaid or (B) 50% of the sum of (1) the amount prepaid and (2) the amount of principal scheduled under the terms of the Base Interest Rate Loan being prepaid to be outstanding at the relevant Base Rate Maturity Date). Present value under this note is determined by discounting the above product to present value using the Yield Rate as the annual discount factor.

b. In no event shall Bank be obligated to make any payment or refund to Debtor, nor shall Debtor be entitled to any setoff or other claim against Bank, should the return which Bank could obtain under this prepayment formula exceed the interest that Bank would have received if no prepayment had occurred. All prepayments shall include payment of accrued interest on the principal amount so prepaid and shall be applied to payment of interest before application of principal. A determination by Bank as to the prepayment fee amount, if any, shall be conclusive.

4

c. Bank shall provide Debtor a statement of the amount payable on account of prepayment. Debtor acknowledges that (i) Bank establishes a Base Interest Rate upon the understanding that it apply to the base Interest Rate Loan for the entire Interest Period, and (ii) Bank would not lend to Debtor without Debtor's express agreement to pay Bank the prepayment fee described above.

5. DEFAULT AND ACCELERATION OF TIME FOR PAYMENT. Default shall include, but not be limited to, any of the following: (a) the failure of Debtor to make any payment required under this note when due; (b) any breach, misrepresentation or other default by Debtor, any guarantor, co-maker, endorser, or any person or entity other than Debtor providing security for this note (hereinafter individually and collectively referred to as the "Obligor") under any security agreement, guaranty or other agreement between Bank and any Obligor; (c) the insolvency of any Obligor or the failure of any Obligor generally to pay such Obligor's debts as such debts become due; (d) the commencement as to any Obligor of any voluntary or involuntary proceeding under any laws relating to bankruptcy, insolvency, reorganization, arrangement, debt adjustment or debtor relief; (e) the assignment by any Obligor for the benefit of such Obligor's creditors; (f) the appointment, or commencement of any proceeding for the appointment of a receiver, trustee, custodian or similar official for all or substantially all of any Obligor's property; (g) the commencement of any proceeding for the dissolution or liquidation of any Obligor; (h) the termination of existence or death of any Obligor; (l) the revocation of any guaranty or subordination agreement given in connection with this note; (j) the failure of any Obligor to comply with any order, judgement, injunction, decree, writ or demand of any court or other public authority; (k) the filing or recording against any Obligor, or the property of any Obligor, of any notice of levy, notice to withhold, or other legal process for taxes other than property taxes; (l) the default by any Obligor personally liable for amounts owed hereunder on any obligation concerning the borrowing of money; (m) the issuance against any Obligor, or the property of any Obligor, of any writ of attachment, execution, or other judicial lien; or (n) the deterioration of the financial condition of any Obligor which results in Bank deeming itself, in good faith, insecure. Upon the occurrence of any such default, Bank, in its discretion, may cease to advance funds hereunder and may declare all obligations under this note immediately due and payable; however, upon the occurrence of an event of default under d, a, f, or g, all principal and interest shall automatically become immediately due and payable.

6. ADDITIONAL AGREEMENTS OF DEBTOR. If any amounts owing under this note are not paid when due, Debtor promises to pay all costs and expenses, including reasonable attorneys' fees, incurred by Bank in the collection or enforcement of this note. Debtor and any endorsers of this note, for the maximum period of time and the full extent permitted by law, (a) waive diligence, presentment, demand, notice of nonpayment, protest, notice of protest, and notice of every kind; (b) waive the right to assert the defense of any statute of limitations to any debt or obligation hereunder; and (c) consent to renewals and extensions of time for the payment of any amounts due under this note.

The receipt of any check or other item of payment by Bank, at its option, shall not be considered a payment on account until such check or other item of payment is honored when presented for payment at the drawee bank. Bank may delay the credit of such payment based upon Bank's schedule of funds availability, and interest under this note shall accrue until the funds are deemed collected. In any action brought under or arising out of this note, Debtor and any Obligor, including their successors and assigns, hereby consent to the jurisdiction of any competent court within the State of California, as provided in any alternative dispute resolution agreement executed between Debtor and Bank, and consent to service of process by any means authorized by said state's law. The term "Bank" includes, without limitation, any holder of this note. This note shall be construed in accordance with and governed by the laws of the State of California. This note hereby incorporates any alternative dispute resolution agreement previously, concurrently or hereafter executed between Debtor and Bank.

7. DEFINITIONS. As used herein, the following terms shall have the meanings respectively set forth below: "Base Interest Rate" means a rate of interest based on the LIBOR Rate. "Base Interest Rate Loan" means amounts outstanding under this note that bear interest at a Base Interest Rate. "Base Rate Maturity Date" means the last day of the Interest Period with respect to principal outstanding under a Base Interest Rate Loan. "Business Day" means a day on which Bank is open for business for the funding of corporate loans, and, with respect to the rate of Interest based on the LIBOR Rate, on which dealings in U.S. dollar deposits outside of the United States may be carried on by Bank. "Interest Period" means with respect to funds bearing interest at a rate based on the LIBOR Rate, any calendar period of one, three, six, nine or twelve months. In determining an Interest Period, a month means a period that starts on one Business Day in a month and ends on and includes the day preceding the numerically corresponding day in the next month. For any month in which there is no such numerically corresponding day, then as to that month, such day shall be deemed to be the last calendar day of such month. Any Interest Period which would otherwise end on a non-Business Day shall end on the next succeeding Business Day unless that is the first day of a month, in which event such Interest Period shall end on the next preceding Business Day. "LIBOR Rate" means a per annum rate of interest (rounded upward, if necessary, to the nearest 1/100 of 1%) at which dollar deposits, in immediately available funds and in lawful money of the United States would be offered to Bank, outside of the United States, for a term coinciding with the Interest Period selected by Debtor and for an amount equal to the amount of principal covered by Debtor's interest rate selection, plus Bank's costs, including the cost, if any, of reserve requirements. "Origination Date" means the first day of the Interest Period. "Reference Rate" means the rate announced by Bank from time to time at its corporate headquarters as its Reference Rate. The Reference Rate is an index rate determined by Bank from time to time as a means of pricing certain extensions of credit and is neither directly tied to any external rate of interest or index nor necessarily the lowest rate of interest charged by Bank at any given time.

THIS ALTERNATIVE DISPUTE RESOLUTION AGREEMENT ("Agreement") is made and
entered into as of the 10TH day of JULY, 2000, by and between the undersigned ("Obligor") and Union Bank of California, N.A. ("Bank") (Obligor and Bank herein collectively, the "Parties" and individually, a "Party").

1. CLAIMS SUBJECT TO JUDICIAL REFERENCE; SELECTION OF REFEREE. All Claims, including any and all questions of law or fact relating thereto, shall, at the written request of any Party, be determined by Reference. The Parties shall select a single neutral referee, who shall be a retired state or federal court judge with at least five years of judicial experience in civil matters. In the event that the Parties cannot agree upon a referee, the referee shall be appointed by the court. The Parties shall equally bear the fees and expenses of the referee unless the referee otherwise provides in the statement of decision.

2. WAIVER OF JURY TRIAL. In connection with a Reference or any other action or proceeding, whether brought in state or federal court, the Parties hereby expressly, intentionally and deliberately waive any right they may otherwise have to trial by jury of any Claim.

3. CONDUCT OF REFERENCE. Except as provided in this Agreement, the Reference shall be conducted pursuant to Applicable State Law. The referee shall determine all issues relating to the applicability, interpretation, legality and enforceability of this Agreement.

4. PROVISIONAL REMEDIES, SELF-HELP AND FORECLOSURE. No provision of this Agreement shall limit the right of any Party to (a) exercise self-help remedies including, without limitation, set-off, (b) foreclosure against or sell any collateral, by power of sale or otherwise or (c) obtain or oppose provisional or ancillary remedies from a court of competent jurisdiction before, after or during the pendency of the Reference. The exercise of, or opposition to, any such remedy does not waive the right of any Party to Reference pursuant to this Agreement.

5. LIMITATION ON DAMAGES. In the event that punitive damages are permitted under Applicable State Law, the amount thereof shall not exceed a sum equal to three times the amount of actual damages as determined by the referee.

6. SEVERABILITY. In the event that any provision of this Agreement is found to be illegal or unenforceable, the remainder of this Agreement shall remain in full force and effect.

7. MISCELLANEOUS. In the event that multiple Claims are asserted, some of which are found not subject to this Agreement, the Parties agree to say the proceedings of the Claims not subject to this Agreement until all other Claims are resolved in accordance with this Agreement. In the event that Claims are asserted against multiple parties, some of whom are not subject to this Agreement, the Parties agree to sever the Claims subject to this Agreement and resolve them in accordance with this Agreement. In the event of any challenge to the legality or enforceability of this Agreement, the prevailing Party shall be entitled to recover the costs and expenses, including reasonable attorneys' fees, incurred by it in connection therewith. Applicable State Law shall govern the interpretation of this Agreement. This Agreement fully states all of the terms and conditions of the Parties' agreement regarding the matters mentioned in, or incidental to, this Agreement.
