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, 1997 included in its Form 10-K/A.

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 less than one year are classified as short-term
investments. As of June 30, 1998, the Company's short-term investments consist
of U.S. Government backed securities and commercial paper, which are classified
as held to maturity and are valued using the amortized cost method which
approximates market.

Revenue Recognition
-------------------
Product revenues consist of sales to OEMs and merchant power supply
manufacturers and to 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 such 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.

New Accounting Standards
------------------------
In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and presentation of
comprehensive income. SFAS No. 130 requires companies to report a new measure of
income. The Company adopted SFAS No. 130 in the first quarter of 1998.
"Comprehensive Income" is to include foreign currency translation gains and
losses and other unrealized gains and losses that have historically been
excluded from net income and reflected instead in equity. The adoption of SFAS
No. 130 did not have a material impact on the Company's financial statements.

POWER INTEGRATIONS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information," which
requires companies to report financial and descriptive information about its
reportable operating segments. SFAS No. 131 will be adopted by the Company in
its 1998 annual consolidated financial statements. The Company anticipates that
SFAS No. 131 will not have a material impact on its financial statements.

3. INVENTORIES:

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

4. SIGNIFICANT CUSTOMERS AND EXPORT SALES:

Customer Concentration
----------------------
The Company's end user base is highly concentrated and a relatively small
number of OEMs and distributors accounted for a significant portion of the
Company's net revenues. For the six months ended June 30, 1998 and 1997, ten
customers accounted for approximately 65% and 70% of total net revenues,
respectively.

The following customers accounted for more than 10% of total net revenues:

The Company markets its products in North America and in foreign countries
through its sales personnel and a worldwide network of independent sales
representatives and distributors. As a percentage of total net revenues, export
sales, which consist of domestic sales to customers in foreign countries, are
comprised of the following:

5. EARNINGS PER SHARE:

In December 1997, the Company adopted Statement of Financial Accounting
Standards (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 is calculated by dividing net income by the weighted
average shares of common stock outstanding during the period. Diluted earnings
per share is 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 warrants
computed 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):

6. PROVISION FOR INCOME TAXES:

Income tax expense for the six month periods ended June 30, 1998 and 1997
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.

7. LEGAL PROCEEDINGS:

In July 1998, the Company filed a complaint in the U.S. District Court,
Northern District of California against its largest end user, Motorola. The suit
alleges that Motorola, Inc. ("Motorola"), has infringed and continues to
infringe on one of the Company's TOPSwitch circuit patents and one of the
Company's high-voltage semiconductor device patents. The Company seeks, among
other things, an order enjoining Motorola from infringing on the Company's
patents and an award for damages resulting from the alleged infringement.

Litigation may be necessary to resolve the claims asserted by the Company
against Motorola, and any claims which Motorola may assert in the future against
the Company, and to defend, enforce and protect the Company's intellectual
property rights. There can be no assurance that the Company will prevail in any
litigation with Motorola, or any other party. Any such litigation, whether or
not determined in the Company's favor or settled by the Company, would be costly
and would divert the efforts and attention of the Company's management and
technical personnel from normal business operations, which could have a material
adverse effect on the Company's

POWER INTEGRATIONS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

business, financial condition and results of operations. Adverse
determinations in litigation could result in the loss of certain of the
Company's proprietary rights, subject the Company to significant liabilities,
require the Company to seek licenses from third parties or prevent the Company
from licensing its technology, any of which could have a material adverse
effect on the Company's business, financial condition and results of
operations.

OVERVIEW

Power Integrations, Inc. (the "Company") designs, develops and markets
proprietary, high-voltage analog integrated circuits ("ICs") for use in AC to DC
power conversion. The Company has targeted high-volume power supply markets,
including the cellular telephone, personal computer, cable and direct broadcast
satellite and various consumer and industrial electronics markets. The Company
initially focuses on those markets that are sensitive to size, portability,
energy efficiency and time-to-market. The Company believes its patented
TOPSwitch ICs, introduced in 1994, are the first highly integrated power
conversion ICs to achieve widespread market acceptance. The Company introduced
an enhanced family of ICs, TOPSwitch-II, in April 1997.

COMPARISON OF THE THREE AND SIX MONTHS ENDED JUNE 30, 1998 AND 1997

Net revenues. Net revenues consist of revenues from product sales, which
------------
are calculated net of returns and allowances, plus royalties paid by licensees
of the Company's technology. Net revenues for the second quarter ended June 30,
1998 were $15.1 million compared to $10.0 million for the second quarter of
1997, an increase of $5.1 million, or 50%. Net revenues for the six months ended
June 30, 1998 were $29.5 million compared to $17.1 million for the comparable
period of 1997, an increase of $12.4 million, or 73%.

Net revenues from product sales represented $14.6 million and $9.9 million in
the second quarter of 1998 and 1997, respectively. Net revenues from product
sales represented $28.5 million and $16.7 million in the first half of 1998 and
1997, respectively. The increase in net revenues from product sales for the
three months and six months ended June 30, 1998 was due primarily to higher
sales volume of the Company's TOPSwitch family of products across a larger
customer base. Net revenues also grew because of an increase in royalty
revenues. Royalties were $466,000 for the second quarter of 1998, an increase of
$295,000, or 173%, from the second quarter of 1997. Royalties were $990,000 for
the six months ended June 30, 1998, an increase of $584,000, or 144%, from the
six months ended June 30, 1997.

International sales were $12.4 million in the second quarter of 1998 compared
to $7.9 million for the same period in 1997, an increase of $4.5 million, or
57%, representing 82% of net revenues compared to 78% in the comparable period
of 1997. International sales were $24.0 million for the six months ended June
30, 1998 compared to $12.9 million for the same period in 1997, an increase of
$11.1 million, or 86%, representing 81% of net revenues compared to 79% in the
comparable period of 1997. Although the power supplies using the Company's
products are designed and distributed worldwide, most of such power supplies are
manufactured in Asia. As a result, sales to this region were 71% and 70% of
product sales for the three months ended June 30, 1998 and 1997, respectively,
and 69% and 65% of product sales for the six months ended June 30, 1998 and
1997, respectively. The Company expects international sales to continue to
account for a large portion of the Company's net revenues.

The Company's direct sales are divided approximately 50% to distributors and
50% to OEMs and merchants. For the quarter ended June 30, 1998, net revenues
from three customers accounted for 24%, 12% and 10% of net revenues, and for the
quarter ended June 30, 1997, two of those same customers accounted for 16% and
17% of net revenues. For the six months ended June 30, 1998, net revenues from
two customers accounted for 21% and 13% of net revenues, and for the comparable
period ended June 30, 1997, one of those same customers accounted for 19% of net
revenues and another customer accounted for 13% of net revenues.

The exact dollar amounts and percentages of sales to end customers are
difficult to ascertain because most of such sales occur through distributors or
indirectly through sales to merchant power supply manufacturers which, in turn,
sell power supplies to OEMs. However, the Company estimates that direct and
indirect sales to Motorola, who is the Company's largest end user, accounted for
approximately 13% and 19% of the Company's net revenues for the quarters ended
June 30, 1998 and 1997, respectively, and approximately 9% and 16% of the
Company's net revenues for the six months ended June 30, 1998 and 1997,
respectively. Direct sales to Motorola were approximately 5% and 6% of the
Company's net revenues for the quarters ended June 30, 1998 and 1997,
respectively, and approximately 4% and 5% of the Company's net revenues for
the six months ended June 30,1998 and 1997, respectively.

cost of revenues. The Company's cost of revenues consists primarily of costs
associated with the purchase of wafers, the assembly and packaging of its
products, and internal labor and overhead associated with the testing of both
wafers and packaged components. Gross profit for the second quarter of 1998 was
$6.9 million, or 45.4%, of net revenues, compared to $4.3 million, or 42.4%, of
net revenues for the same period in 1997. Gross profit for the six months ended
June 30, 1998 was $13.3 million, or 45.1%, of net revenues, compared to $7.0
million, or 40.9%, of net revenues for the same period in 1997. The increase in
gross profit for the three months and six months ended June 30, 1998 was
primarily due to the combined effects of the absorption of certain fixed costs
over the increased sales volume, lower prices for wafers, which were partially a
result of favorable Japanese Yen exchange rates, and better manufacturing yields
due to improved test equipment. There can be no assurance that these or other
factors will have a favorable impact on gross profit in future periods.

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. The
Company also expenses prototype wafers and mask sets related to new products as
research and

11
development costs until new products are released to production. Research and
development expenses for the second quarter of 1998 were $1.7 million compared
to $1.2 million for the same period in 1997, an increase of $505,000, or 42%,
representing 11.4% and 12.1% of net revenues, respectively. Research and
development expenses for the first half of 1998 were $3.3 million compared to
$2.3 million for the same period in 1997, an increase of $987,000, or 43%,
representing 11.1% and 13.4% of net revenues, respectively. The increase for the
three months and six months ended June 30, 1998 was primarily due to increased
salaries and other costs related to the hiring of additional engineering
personnel, outside consulting fees and expensed prototype materials resulting
from the transition of foundry manufacturing processes. The Company expects that
research and development expenses will continue to increase in absolute dollars
but will fluctuate as a percentage of 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 the Company's regional
sales and support offices. Sales and marketing expenses for the second quarter
of 1998 were $1.7 million compared to $1.5 million for the same period in 1997,
an increase of $260,000, or 18%, representing 11.4% and 14.6% of net revenues,
respectively. Sales and marketing expenses for the first half of 1998 were $3.6
million compared to $2.6 million for the same period in 1997, an increase of
$1.0 million, or 41%, representing 12.2% and 15.0% of net revenues,
respectively. The increase for the three months and six months ended June 30,
1998 was primarily a result of the addition of personnel to support
international sales and field application engineers and to staff two new sales
offices in Asia which opened in June 1997. The Company expects that sales and
marketing expenses will continue to increase in absolute dollars but will
fluctuate as a percentage of net revenues.

General and administrative expenses. General and administrative expenses
-----------------------------------
consist primarily of employee-related expenses for administration, finance,
human resources, general management and facilities, and consulting, outside
services, legal and auditing expenses. For the quarters ended June 30, 1998 and
1997, general and administrative expenses were $730,000 and $430,000,
respectively, which represented 4.8% and 4.2% of net revenues, respectively. For
the six month periods ended June 30, 1998 and 1997, general and administrative
expenses were $1.3 million and $840,000, respectively, which represented 4.3%
and 4.9% of net revenues, respectively. This increase in absolute dollars was
attributable to additional headcount to support the Company's growth and
additional professional and outside services required by the Company as a result
of its public reporting obligations. The Company expects that general and
administrative expenses will continue to increase in absolute dollars and may
increase as a percentage of net revenues, particularly in light of the Company's
recently filed patent infringement claim against Motorola.

Other income (expense), net. Other income (expense), net, for the second
---------------------------
quarter of 1998 increased by $328,000 over the same period in 1997, and for the
six months ended June 30, 1998 increased by $729,000 over the same period in
1997. The increase for the three months and six months ended June 30, 1998 was
due primarily to additional interest income from an increase in short-term
investments in 1998 and a reduction in interest expense as a result of the
repayment of $3.0 million of subordinated debt in the fourth quarter of 1997.
The Company expects to continue to utilize term debt to finance its capital
equipment needs.

Provision for income taxes. Provision for income taxes represents Federal,
--------------------------
state and foreign taxes. The provision for income taxes was $721,000 for the
second quarter of 1998 compared to $57,000 for the same period in 1997. The
provision for income taxes was $1.4 million for the first half of 1998 compared
to $67,000 for the same period in 1997. The Company used an effective tax rate
of 25% reflecting the profitable results for the 1998 period, while the
provision for 1997 represented minimum tax. The difference between the statutory
rate and the Company's effective tax rate for 1998 is primarily due to the
beneficial impact of net operating loss carryforwards. Utilization of the net
operating loss carryforwards will be subject to an annual limitation due to the
ownership change limitations provided by the Internal Revenue Code of 1986, as
amended, and similar state provisions.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1998, the Company had approximately $32.7 million in cash, cash
equivalents and short-term investments. In addition, under a working capital
line of credit agreement with a bank, the Company can borrow up to $8.0 million
conditional upon meeting certain financial covenants, including maintaining
quarterly profitability and specific financial covenants. As of June 30, 1998,
there were no borrowings outstanding under the line of credit agreement. The
Company has financed a significant portion of its machinery and equipment
through capital

12
equipment leases including an additional equipment financing in the amount of
$1.4 million during the six months ended June 30, 1998. At June 30, 1998,
approximately $4.7 million was outstanding under various capital equipment
leasing agreements.

As of June 30, 1998, the Company had working capital, defined as current
assets less current liabilities, of approximately $33.9 million, which was an
increase of approximately $3.8 million over December 31, 1997. The Company
generated $5.3 million from operating activities during the six months ended
June 30, 1998, reflecting net income of $4.1 million, depreciation of $1.5
million and $330,000 provided by the net change in working capital items. The
net change in working capital items primarily reflects an increase in inventory
of $3.6 million as part of the Company's program to provide shorter lead times
to its customers, a decrease in accounts receivable of $1.1 million, and an
increase of $1.5 million in deferred revenue.

The nature of the semiconductor industry, combined with the current economic
environment, make it very difficult for the Company to predict future liquidity
requirements with certainty. However, the Company believes that its existing
cash, cash equivalents and short-term investments, cash generated from
operations and other existing sources of working capital will be adequate to
finance its operations through the next twelve months.

NEW ACCOUNTING STANDARDS

In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and presentation of
comprehensive income. SFAS No. 130 requires companies to report a new measure of
income. The Company adopted SFAS No. 130 in the first quarter of 1998.
"Comprehensive Income" is to include foreign currency translation gains and
losses and other unrealized gains and losses that have historically been
excluded from net income and reflected instead in equity. The adoption of SFAS
No. 130 did not have a material impact on the Company's financial statements.

In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information," which
requires companies to report financial and descriptive information about its
reportable operating segments. SFAS No. 131 will be adopted by the Company in
its 1998 annual consolidated financial statements. The Company anticipates that
SFAS No. 131 will not have a material impact on its financial statements.
Factors That May Affect Future Results of Operations

FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS

The Company's future results of operations are dependent upon a number of
-------------------------------------------------------------------------
factors, including those described below. For a complete description of such
- ----------------------------------------------------------------------------
factors, see the Company's Form 10-K/A for the year ended December 31, 1997.
- ---------------------------------------------------------------------------

Unpredictable and Fluctuating Operating Results. The Company's quarterly
-----------------------------------------------
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 the Company's control, and may fluctuate significantly in the future.
Although the Company was profitable in the second quarter of 1998, there can be
no assurance that the Company will continue to be profitable in future periods.
The Company believes that period-to-period comparisons are not necessarily
meaningful and should not be relied upon as indicative of future operating
results.

Factors which may affect the Company's net revenues and operating results
include the timing and volume of orders received by the Company; competitive
pressures on selling prices; the volume and timing of orders placed by the
Company with its foundries; the availability of raw materials; fluctuations in
manufacturing yields, whether resulting from the transition to new foundries or
from other factors; changes in product mix including the impact of new product
introduction on existing products; the Company's ability to develop and bring to
market new products and technologies on a timely basis; introduction of products
and technologies by the Company's competitors; market acceptance of the
Company's and its customers' products; the timing of investments in research and
development and sales and marketing; the Company's patent infringement claim
against Motorola; cyclical semiconductor industry conditions; fluctuations in
exchange rates, particularly exchange rates between the U.S. dollar and the
Japanese yen; changes in the international business climate; and economic
conditions generally.

13
The Company's operating results in a future quarter or quarters are likely to
fall below the expectations of public market analysts or investors. In such an
event, the price of the Company's common stock will likely be materially and
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

Concentration of Applications. A limited number of applications of the
-----------------------------
Company's products, primarily in the cellular phone battery chargers and desktop
PC stand-by markets, currently account for approximately one-half of the
Company's net revenues. The Company expects that its 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, characterized by diminished product demand, accelerated erosion of
average selling prices and production over capacity. The Company may experience
substantial period-to-period fluctuations in future operating results due to
general conditions of these markets. The Company's net revenues and operating
results are subject to many of the risks to which the markets for these
applications are subject, and may also be impacted by technological or other
developments in these markets. While the Company continues its efforts to
enhance the cost effectiveness of TOPSwitch-based switchers, there can be no
assurance that the Company will be successful in its efforts, and, in the
absence of a successful competitive response by the Company, demand for the
Company's products would be materially adversely affected. Similarly, if a
competitor of the Company successfully and cost effectively combines desktop PC
stand-by power supplies with the main PC desktop power supplies prior to such
combination by the Company, demand for the Company's products could be
materially adversely affected.

Customer Concentration and Competing Products from Customers. The Company's
------------------------------------------------------------
end user base is highly concentrated and a relatively small number of OEMs,
directly or indirectly through merchant power supply manufacturers, account for
a significant portion of the Company's net revenues. The Company estimates that
its top ten customers, including distributors which resell to large OEMs and
merchant power supply manufacturers, accounted for 65% and 70% of the Company's
net revenues for the six months ended June 30, 1998 and 1997, respectively. The
Company expects that it will continue to be dependent upon a relatively limited
number of customers for a significant portion of its net revenues in future
periods, although no customer is presently obligated either to purchase a
specified amount of products or to provide the Company with binding forecasts of
product purchases for any period. The reduction, delay or cancellation of orders
from one or more of the Company's significant customers, or the discontinuance
of the Company's products by the Company's end users, could materially and
adversely affect the Company's business, financial conditions and results of
operations. The Company has experienced such effects in the past and there can
be no assurance that any of the Company's customers will not reduce, cancel or
delay orders in the future.

Dependence on Wafer Suppliers. The Company outsources all of its
-----------------------------
semiconductor manufacturing and product assembly except for testing and
finishing. The Company has supply arrangements for the production of wafers with
Matsushita Electronics Corporation and an affiliate of Matsushita ("MEC"), and
OKI Electric Industry Co., Ltd. ("OKI"). Although certain aspects of the
Company's relationships with MEC and OKI are contractual, many important aspects
of these relationships depend on the continued cooperation of these strategic
partners and, in many instances, the parties' course of conduct deviates from
the literal provisions of the contracts. There can be no assurance that the
Company and its strategic partners will continue to work together successfully
in the future or that either MEC or OKI will not seek an early termination of
its wafer supply agreement with the Company.

The Company's wafer supply contract with OKI terminates on October 1, 1998.
The Company is negotiating a renewal of this contract, however, there can be no
assurance that the Company will execute a renewal contract with OKI for the
supply of wafers. The Company's wafer supply contract with MEC terminates in
June 2000. There can be no assurance that the Company will be able to reach an
agreement with MEC to extend the term of its wafer supply agreement. The
Company's failure to reach, in a timely fashion, an extension of either
agreement or to enter into an arrangement with another manufacturer, could
result in material disruptions in supply. Certain contractual provisions limit
the conditions under which the Company can enter into such arrangements with
other Japanese manufacturers or their subsidiaries during the term of the
agreement with MEC. In the event of a supply disruption with OKI or MEC, if
the Company were unable to qualify alternative manufacturing sources for
existing or new products in a timely manner or if such sources were unable to
produce
14
wafers with acceptable manufacturing yields, the Company's business, financial
condition and operating results would be materially and adversely affected.

From time to time in the past, the Company has been unable to fully satisfy
customer requests for its products. Any significant disruptions in deliveries of
the Company's products to its customers would materially and adversely affect
the Company's business and operating results.

Risks of Outside Manufacturing and Assembly; Sole Source Risks. The Company
--------------------------------------------------------------
depends on MEC and OKI to produce wafers, and independent subcontractors to
assemble finished products, at acceptable yields and to deliver them to the
Company in a timely manner. To the extent the wafer foundries do not achieve
acceptable manufacturing yields or they experience product shipment delays, the
Company's financial condition or results of operations would be materially and
adversely affected. The Company's IC assembly process requires a sole source
high-voltage molding compound that is difficult to process. This compound and
its required processes, together with the other non-standard materials and
processes needed to assemble the Company's 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 and adversely affect yields and cost to manufacture. Good
production yields are particularly important to the Company's business and
financial results, including its ability to meet customers' demand for products
and to maintain profitability. As the Company continues to increase its product
output, there can be no assurance that the Company's foundries and assemblers
will not experience a decrease in yields. Moreover, there can be no assurance
that acceptable yields will be maintainable in the future.

Risks of International Sales. Sales to customers outside of the United
----------------------------
States represented 81% and 79% for the six months ended June 30, 1998 and 1997,
respectively. These sales involve a number of inherent risks, including
imposition of government controls, currency exchange fluctuations, potential
insolvency of international distributors and representatives, reduced protection
for intellectual property rights in some countries, the impact of recessionary
environments in economies outside the United States, political instability,
generally longer receivables collection periods, tariffs and other trade
barriers and restrictions, and the burdens of complying with a variety of
foreign laws. Furthermore, because substantially all of the Company's foreign
sales are denominated in U.S. dollars, increase in the value of the dollar would
increase the price in local currencies of the Company's products in foreign
markets and make the Company's products relatively more expensive and less price
competitive than competitors' products that are priced in local currencies. The
Company is exposed to additional risks to the extent that the products of its
customers are subject to foreign currency or other international risks. There
can be no assurance that these factors will not have an adverse effect on the
Company's future international sales and, consequently, on the Company's
business, financial condition or operating results.

New Products and Technological Change. The Company's future success depends
-------------------------------------
in significant part upon its ability to develop new ICs for high-voltage power
conversion for existing and new markets, to introduce such products in a timely
manner and to have such products selected for design into products of leading
manufacturers. The development of these new devices is highly complex, and from
time to time the Company has experienced delays in completing the development of
new products. There can be no assurance that the Company will be able to adjust
to changing market demands as quickly and cost-effectively as necessary to
compete successfully. Furthermore, there can be no assurance that the Company
will be able to introduce new products in a timely and cost-effective manner or
in sufficient quantities to meet customer demand or that such products will
achieve market acceptance. The Company's or its customers' failure to develop
and introduce new products successfully and in a timely manner would materially
adversely affect the Company's business, financial condition or operating
results.

Lengthy Sales Cycle. The Company's products are generally incorporated into
-------------------
a customer's products at the design stage. However, customer decisions to use
the Company's products (design wins), which can often require significant
expenditures by the Company without any assurance of success, often precede
volume sales, if any, by a year or more. If a customer decides at the design
stage not to incorporate the Company's products into its product, the Company
will not have another opportunity for a design win with respect to that product
for many months or years. Because of such a lengthy sales cycle, the Company may
experience a delay between increasing expenses for research and development and
its sales and marketing efforts and the generation of volume production
revenues, if any, from such expenditures. Failure by the Company to timely
develop and introduce products that are

15
incorporated into its customers' products could have a material adverse effect
on the Company's business, financial condition or results of operations.

Product Quality, Performance and Reliability. The fabrication and assembly
--------------------------------------------
of ICs is a highly complex and precise process. The Company expects that its
customers will continue to establish demanding specifications for quality,
performance and reliability that must be met by the Company's products. ICs as
complex as those offered by the Company often encounter development delays and
may contain undetected defects or failures when first introduced or after
commencement of commercial shipments. The Company has from time to time in the
past experienced product quality, performance or reliability problems. There can
be no assurance that defects or failures relating to the Company's product
quality, performance and reliability will not occur in the future or that such
defects or failures will not have a material adverse effect on the Company's
operating results.

Competition. The high-voltage power supply industry is intensely
-----------
competitive and characterized by extreme price sensitivity. Accordingly, the
most significant competitive factor in the target markets for the Company's
products is cost effectiveness. The Company's products face competition from
alternative technologies, primarily discrete switchers. The Company believes
that at current pricing, the TOPSwitch families of products offer favorable cost
performance benefits compared to discrete switchers in many high-volume
applications. However, any significant erosion in the price of discrete
components, such as high voltage Bipolar and MOSFET transistors and PWM
controller ICs, could adversely affect the cost effectiveness of the TOPSwitch
products. Also, older alternative technologies to switchers are more cost-
effective than switchers that use the Company's TOPSwitch products in certain
power ranges for certain applications. The Company is continuing its efforts to
enhance the cost effectiveness of TOPSwitch-based switchers in the lower power
ranges. There can be no assurance that the Company will be successful in these
efforts.

In addition, the Company faces competition from MEC, which currently
manufactures and sells its versions of the Company's TOPSwitch families of
products under the right (exclusive during the term of the contract as to other
Japanese companies, except OKI, and their subsidiaries) granted by the Company
to manufacture and sell products using the Company's technology to Japanese
companies worldwide and to subsidiaries of Japanese companies located in Asia.
Beginning in April 1997, the Company agreed not to sell its products to new
customers in Japan. The Company's TOPSwitch product families have also begun to
meet additional competition from hybrid and single high-voltage ICs similar to
TOPSwitch. These competing products are being developed or have been developed
and are being produced by companies such as Motorola, SGS, Samsung and Sanken.
The Company expects competition to increase as Motorola, SGS, Samsung, Sanken
and possibly other companies develop and introduce new products.

The Company's ability to compete in its target markets also depends on such
factors as the timing and success of new product introductions by the Company
and its competitors, the pace at which the Company's customers incorporate the
Company's products into their end user products, availability of wafer
fabrication and finished good manufacturing capability, availability of adequate
sources of raw materials, protection of Company products by effective
utilization of intellectual property laws and general economic conditions. There
can be no assurance that the Company's products will continue to compete
favorably or that the Company will be successful in the face of increasing
competition from new products and enhancements introduced by existing
competitors or new companies entering this market. Failure of the Company to
compete successfully in the high-voltage power supply business would materially
and adversely affect the Company's business, financial condition and results of
operations.

Dependence on Proprietary Technology. The Company's future success depends
------------------------------------
in part upon its ability to protect its intellectual property, including
patents, trade secrets, and know-how, and to continue its technological
innovation. There can be no assurance that the steps taken by the Company to
protect its intellectual property will be adequate to prevent misappropriation
or that others will not develop competitive technologies or products.

The semiconductor industry is characterized by frequent litigation regarding
patent and other intellectual property rights. While the Company has not
received formal notice of any infringement of the right of any third party,
questions of infringement in the semiconductor field involve highly technical
and subjective analyses. Litigation may be necessary in the future to enforce
the Company's patents and other intellectual property rights, to protect the
Company's trade secrets, to determine the validity and scope of the proprietary
rights of others, or to defend against claims of infringement or invalidity, and
there can be no assurance that the Company would prevail in any future
litigation. In addition, the laws of certain foreign countries in which the
Company's technology is or

16
may in the future be licensed may not protect the Company's intellectual
property rights to the same extent as the laws of the United States, thus
increasing the possibility of infringement of the Company's intellectual
property.

Motorola Litigation. In July 1998, the Company filed a complaint in the
-------------------
U.S. District Court, Northern District of California against its largest end
user, Motorola. The suit alleges that Motorola has infringed and continues to
infringe on one of the Company's TOPSwitch circuit patents and one of the
Company's high-voltage semiconductor device patents. The Company seeks, among
other things, an order enjoining Motorola from infringing on the Company's
patents and an award for damages resulting from the alleged infringement.

Litigation may be necessary to resolve the claims asserted by the Company
against Motorola, and any claims which Motorola may assert in the future
against the Company, and to defend, enforce and protect the Company's
intellectual property rights. There can be no assurance that the Company will
prevail in any litigation with Motorola, or any other party. Any such
litigation, whether or not determined in the Company's favor or settled by the
Company, would be costly and would divert the efforts and attention of the
Company's management and technical personnel from normal business operations,
which could have a material adverse effect on the Company's business,
financial condition and results of operations. Adverse determinations in
litigation could result in the loss of certain of the Company's proprietary
rights, subject the Company to significant liabilities, require the Company to
seek licenses from third parties or prevent the Company from licensing its
technology, any of which could have a material adverse effect on the Company's
business, financial condition and results of operations.

Dependence on Key Personnel. The Company's success depends to a significant
---------------------------
extent upon the continued service of its executive officers and other key
management and technical personnel, and on its ability to continue to attract,
retain and motivate qualified personnel, such as experienced systems
applications engineers. The loss of the services of one or more of the Company's
engineers, executive officers or other key personnel or the Company's inability
to recruit replacements for such personnel or to otherwise attract, retain and
motivate qualified personnel could have a material adverse effect on the
Company's business, financial condition or operating results. The Company does
not have long-term employment contracts with any of its employees.

Management of Growth. The Company has experienced a period of rapid growth
--------------------
and expansion which has placed, and continues to place, a significant strain on
its resources. To accommodate this growth, the Company will be required to
implement a variety of new and upgraded operational and financial systems,
procedures and controls, including the improvement of its accounting and other
internal management systems, all of which may require substantial management
efforts. There can be no assurance that such efforts can be accomplished
successfully.

Year 2000 Compliance. The Company is aware of the issues associated with
--------------------
the programming code in existing computer systems and software products as the
year 2000 approaches. Computer programs that are written using two digits rather
than four digits to define the applicable year, may have date-sensitive software
and, for instance, may recognize a date using 00 as the year 1900 rather than
the year 2000 ("Date Code Dependency"). Systems that do not properly recognize
such information could generate erroneous data or cause a system to fail. The
Company is in the process of defining costs, issues and uncertainties associated
with making the Company's internal-use software applications compliant with the
Year 2000. In general, the Company expects to resolve the Year 2000 issues
through planned replacement upgrades of its software applications. Management
does not expect the Year 2000 issues to have a material impact on the Company's
business or future results of operations. However, if the planned replacement
upgrades to its software applications are not made, or are not completed on a
timely basis, the Year 2000 issues could have a material impact on the
operations of the Company. The Company currently expects that its internal-use
software applications will be Year 2000 compliant by no later than June 1999,
before any Date Code Dependencies within the Company's internal systems would
have a material adverse impact on the Company's operations. The cost of the
project and the date on which the Company believes it will complete the Year
2000 upgrades are based on management's best estimates, which were derived
utilizing numerous assumptions of future events, including the availability of
certain resources and other factors. However, there can be no guarantee that
these estimates will be achieved and actual results could differ materially from
those anticipated. Specific factors that might cause such material differences
include, but are not limited to, the availability and cost of personnel trained
in this area, the ability to locate and correct all relevant computer codes, and
similar uncertainties.

Possible Volatility of Stock. The stock market has from time to time
----------------------------
experienced significant price and volume fluctuations which have particularly
affected the market prices of the stock of high technology companies, and

17
which may be unrelated to the operating performance of particular companies.
Factors such as technology and product announcements by the Company or by
competitors, disputes relating to patents and proprietary rights, and failures
or delays in the Company's development program may have a significant effect on
the market price of the Company's common stock.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In July 1998, the Company filed a complaint in the U.S. District Court,
Northern District of California against its largest end user, Motorola. The
suit alleges that Motorola has infringed and continues to infringe on one of the
Company's TOPSwitch circuit patents and one of the Company's high-voltage
semiconductor device patents. The Company seeks, among other things, an order
enjoining Motorola from infringing on the Company's patents and an award for
damages resulting from the alleged infringement.

Litigation may be necessary to resolve the claims asserted by the Company
against Motorola, and any claims which Motorola may assert in the future
against the Company, and to defend, enforce and protect the Company's
intellectual property rights. There can be no assurance that the Company will
prevail in any litigation with Motorola, or any other party. Any such
litigation, whether or not determined in the Company's favor or settled by the
Company, would be costly and would divert the efforts and attention of the
Company's management and technical personnel from normal business operations,
which could have a material adverse effect on the Company's business,
financial condition and results of operations. Adverse determinations in
litigation could result in the loss of certain of the Company's proprietary
rights, subject the Company to significant liabilities, require the Company to
seek licenses from third parties or prevent the Company from licensing its
technology, any of which could have a material adverse effect on the Company's
business, financial condition and results of operations.
