                                  OUR BUSINESS

    We design, develop and market high performance integrated circuits for the
computing, communications, and consumer electronics markets. Our product
portfolio includes integrated circuit timing devices and EMI reduction and high
performance logic integrated circuits. We believe our gate-array-based
architecture, proprietary input/output structures and extensive mixed-signal
cell library enable us to deliver flexible, high performance solutions to our
customers faster than many of our competitors, which in turn assists our
customers in achieving their time-to-market objectives. Our design methodology
gives us fast design and prototype cycle times and enables rapid product
introductions. We sell our products to leading systems manufacturers in the
computing, communications and consumer electronics markets. Our customers
include Apple, Canon, Cisco, Dell, Fujitsu Siemens, Hewlett-Packard, IBM, NEC,
Panasonic, Pioneer, Sharp, Samsung, Sanyo, Sony and Xerox.

    We believe that we have developed a compelling product portfolio, as
evidenced by our significant design wins with industry leaders, such as Compaq
and Cisco, which has resulted in the integration of our products into some of
Compaq's personal computers and Cisco's leading-edge routers. In addition, our
timing devices are designed into the Intel reference mobile motherboard. We have
also successfully penetrated the digital camera, DVD and minidisc player markets
with recent design wins at Sanyo, Sony and Kenwood.

                                OUR OPPORTUNITY

    There exists a growing demand for fast, high-bandwidth electronic systems
characterized by ever-improving performance, flexibility, reliability and
functionality, as well as decreasing size, cost and power consumption. This
demand has resulted in both the development of new, and the enhancement of
existing, electronic systems, such as digital cameras, DVD players, game
consoles, internet appliances, network routers and switches, notebook computers
and set-top boxes.

    The components of these electronic systems, which include microprocessors,
memory, logic, and timing devices, must continue to increase in performance in
order to enable the continued development of higher performance systems.
Advances in the development of a particular type of integrated circuit timing
device, known as a clock, are particularly critical as they generate the timing
signals necessary for communication among the components within systems as well
as between systems. Other integrated circuits that are becoming increasingly
important in complex, high-speed systems such as computer servers, workstations
and networking systems, where data transfers at optimum speeds are essential,
include zero delay buffers and high performance, low power logic. High
performance electronics systems often emit elevated levels of electromagnetic
interference, or EMI. Because EMI is regulated by the Federal Communications
Commission, systems manufacturers are seeking solutions to reduce levels of EMI.

    In order to meet the demand for higher performance systems in the computing,
communications and consumer electronics markets, systems manufacturers require
high performance integrated circuits with programmable features that allow the
manufacturers to rapidly design and test systems, assisting them in meeting
their time-to-market and cost objectives.

                                  RISK FACTORS

    THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD CAREFULLY CONSIDER
THE RISKS DESCRIBED BELOW AND THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS
BEFORE PURCHASING OUR COMMON SHARES. IF ANY OF THE FOLLOWING RISKS OCCUR, OUR
BUSINESS, OPERATING RESULTS AND FINANCIAL CONDITION COULD BE MATERIALLY
ADVERSELY AFFECTED, THE TRADING PRICE OF OUR COMMON SHARES COULD DECLINE AND YOU
MIGHT LOSE ALL OR PART OF YOUR INVESTMENT. THE RISKS DESCRIBED BELOW ARE NOT THE
ONLY ONES THAT WE FACE. ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN
TO US OR THAT WE CURRENTLY DEEM IMMATERIAL MAY ALSO HARM OUR BUSINESS.

OUR FUTURE OPERATING RESULTS ARE LIKELY TO FLUCTUATE AND THEREFORE MAY FAIL TO
MEET EXPECTATIONS WHICH COULD CAUSE OUR STOCK PRICE TO DECLINE.

    Our operating results have varied widely in the past and are likely to do so
in the future. In addition, our operating results may not follow any past
trends. Our future operating results will depend on many factors and may fail to
meet our expectations for a number of reasons, including those set forth in
these risk factors. Any failure to meet expectations could cause our stock price
to significantly fluctuate or decline.

    Factors that could cause our operating results to fluctuate include risks
related to our internal operations, our dependence on our suppliers and
customers and other risks affecting our industry generally. These factors are
difficult or impossible to forecast. We place orders to purchase our products
from independent foundries several months in advance of the scheduled delivery
date, often in advance of receiving firm orders from our customers. If
anticipated shipments in any quarter are canceled or do not occur as quickly as
expected, expense and inventory levels could be disproportionately high. A
significant portion of our expenses are relatively fixed, and the timing of
increases in expenses is based in large part on our forecast of future revenue.
As a result, if revenue does not meet our expectations we may be unable to
quickly adjust expenses to levels appropriate to actual revenue, which could
harm our operating results.

    As a result of these factors, our operating results may vary significantly
from quarter to quarter. Any shortfall in revenue or net income from levels
expected by securities analysts or investors could cause a decline in the
trading price of our stock.

WE DEPEND ON THE FREQUENT INTRODUCTION OF NEW PRODUCTS AND OUR INABILITY TO
DEVELOP THESE NEW PRODUCTS COULD ADVERSELY AFFECT OUR BUSINESS.

    The markets for our products are characterized by rapidly changing
technology, evolving industry standards and frequent new product introductions.
Product life cycles are continually becoming shorter, which may cause the gross
margins of semiconductor products to decline as the next generation of
competitive products is introduced. Therefore, our future success is highly
dependent upon our ability to frequently develop new products, introduce them in
commercial quantities to the marketplace and have them selected for inclusion in
products of systems manufacturers. Our failure to develop new products, to have
our products available in commercial quantities ahead of competitive products or
to have them selected for inclusion in products of manufacturers would have a
material adverse effect on our results of operations and financial condition.

WE DERIVE MOST OF OUR REVENUE FROM SALES TO A SMALL NUMBER OF LARGE
MANUFACTURERS, AND IF WE ARE NOT ABLE TO RETAIN THESE CUSTOMERS, OR THEY
RESCHEDULE, REDUCE OR CANCEL ORDERS, OUR REVENUE WOULD BE REDUCED AND OUR
FINANCIAL RESULTS WOULD SUFFER.

    Our largest customers account for a substantial percentage of our revenue.
During fiscal 2000, sales of our products to Apple Computer, Dell Computer and
IBM, directly and through distributors and contract manufacturers, accounted for
approximately 22.7%, 19.6% and 12.4%, respectively, of our net revenue. During
the first quarter of fiscal 2001, sales to Apple Computer, Dell Computer and

                                       7
<PAGE>
Sanyo accounted for approximately 19.4%, 21.0% and 10.6%, respectively, of our
total revenue. Sales to these large customers have varied significantly on a
quarterly and annual basis and will continue to fluctuate in the future. We
cannot assure you that we will be able to retain our key customers, that we will
be able to attract additional customers or that our customers will be successful
in selling their products which incorporate our integrated circuits. The loss of
one or more of our largest customers, any substantial reduction or delay in
sales to these customers or their contract manufacturers, or our inability to
successfully develop relationships with additional customers could harm our
sales and financial results. In addition, any difficulty in collecting amounts
due from one or more key customers could harm our financial results.

WE ARE SUBSTANTIALLY DEPENDENT ON TWO OF OUR PRODUCT FAMILIES. ANY FAILURE TO
CONTINUE TO GROW THESE PRODUCT FAMILIES WOULD HAVE A NEGATIVE EFFECT ON OUR
REVENUE AND FINANCIAL RESULTS.

    Our business, revenue and operating results are heavily dependent on our
clock and EMI reduction product families. In fiscal 2000, sales of clocks
comprised 62% of our revenue and sales of EMI reduction integrated circuits
comprised 31% of our revenue. If sales of these product families decline, it may
have a disproportionate effect on our revenue and operating results. For
example, the growth in sales of our EMI reduction products faces several
potential risks. If the Federal Communications Commission changes or rescinds
existing EMI emission standards, the demand for our EMI reduction products would
decline or cease. In addition, if manufacturers develop alternative solutions to
achieve EMI reduction, the demand for our EMI reduction devices will not grow
according to our forecasts. Any failure to continue to grow our core clock and
EMI reduction product families would have a negative effect on our revenue and
financial results.

WE RELY ON INDEPENDENT FOUNDRIES FOR THE MANUFACTURE OF OUR INTEGRATED CIRCUITS,
AND THE FAILURE OF ANY OF THESE SUPPLIERS TO DELIVER PRODUCTS OR OTHERWISE
PERFORM AS REQUESTED COULD DAMAGE OUR RELATIONSHIPS WITH OUR CUSTOMERS AND HARM
OUR SALES AND FINANCIAL RESULTS.

    We do not operate any manufacturing facilities, and we rely on independent
foundries to manufacture all of our products. These independent foundries
fabricate products for other companies, including some of our competitors, and
may also produce products of their own design. From time to time, there are
manufacturing capacity shortages in the semiconductor industry. We do not have
long-term supply contracts with any of our suppliers. Therefore, our suppliers
are not obligated to manufacture products for us for any specific period, in any
specific quantity or at any specified price, except as may be provided in a
particular purchase order.

    Our reliance on independent foundries involves a number of risks, including:

    - the inability to obtain adequate manufacturing capacity;

    - the unavailability of or interruption in access to certain process
      technologies necessary for the manufacture of our products;

    - reduced control over delivery schedules, quality assurance, manufacturing
      yields and costs; and

    - potential misappropriation of our intellectual property.

    In fiscal 1999 and fiscal 2000, we purchased all of our wafers from IBM
Microelectronics, Chartered Semiconductor and Tower Semiconductor. If one or
more of these foundries is unable or unwilling to produce adequate supplies of
processed wafers on a timely basis, it could cause significant delays and
expense in locating a new foundry and redesigning circuits to be compatible with
the new manufacturer's processes and, consequently, could have a material
adverse effect on our results of operations and financial condition.

                                       8
<PAGE>
    We also depend upon our wafer suppliers to participate in process
improvement efforts, such as the transition to finer geometries. If our
suppliers are unable or unwilling to do so, our development and introduction of
new products could be delayed. Furthermore, sudden shortages of raw materials or
production capacity constraints can lead wafer suppliers to allocate available
capacity to customers other than us or for the suppliers' internal uses,
interrupting our ability to meet our product delivery obligations. Any
significant interruption in our wafer supply would seriously harm our
development cycle for our products, providing time-to-market advantages to our
competitors that have in-house fabrication capacity.

IF OUR INDEPENDENT FOUNDRIES DO NOT ACHIEVE SATISFACTORY YIELDS, OUR
RELATIONSHIPS WITH OUR CUSTOMERS MAY BE HARMED.

    The fabrication of silicon wafers is a complex process. Minute levels of
contaminants in the manufacturing environment, defects in photomasks used to
print circuits on a wafer, difficulties in the fabrication process or other
factors can cause a substantial portion of the integrated circuits on a wafer to
be non-functional. Many of these problems are difficult to detect at an early
stage of the manufacturing process and may be time consuming and expensive to
correct. As a result, foundries often experience problems achieving acceptable
yields, which are represented by the number of good integrated circuits as a
proportion of the number of total integrated circuits on any particular wafer.
Poor yields from our independent foundries would reduce our ability to deliver
our products to customers, harm our relationships with our customers and harm
our business and our financial results.

WE DEPEND ON A LIMITED NUMBER OF ASSEMBLY SUBCONTRACTORS WITH WHOM WE DO NOT
HAVE LONG-TERM CONTRACTS. ANY INABILITY OR UNWILLINGNESS OF OUR ASSEMBLY
SUBCONTRACTORS TO MEET OUR ASSEMBLY REQUIREMENTS WOULD DELAY OUR PRODUCT
SHIPMENTS AND HARM OUR BUSINESS.

    We primarily rely on foreign subcontractors for the assembly and packaging
of our products and, to a lesser extent, for the testing of finished products.
We have from time to time experienced difficulties in the timeliness and quality
of product deliveries from our subcontractors and may experience similar or more
severe difficulties in the future. We generally purchase these services through
purchase orders and have no guaranteed arrangements with these subcontractors.
These subcontractors could cease to meet our requirements for components or
services, or there could be a significant disruption in supplies from them, or
degradation in the quality of components or services supplied by them. Any
circumstance that would require us to qualify alternative assembly and packaging
sources could delay shipments, result in the loss of customers and limit or
reduce our revenue.

OUR INDUSTRY IS HIGHLY CYCLICAL AND DOWNTURNS IN THE BUSINESS CYCLE COULD REDUCE
OUR REVENUE AND THE PROFITABILITY OF OUR BUSINESS.

    The semiconductor industry is highly cyclical. Downturns in the industry
often occur in connection with, or anticipation of, maturing product cycles for
both semiconductor companies and their customers and declines in general
economic conditions. These downturns have been characterized by abrupt
fluctuations in product demand, production over-capacity and accelerated decline
of average selling prices. In some cases, these downturns have lasted more than
one year. A downturn in the semiconductor industry could reduce our revenue if
demand drops or our gross margins if average selling prices decline. We may in
the future experience substantial period-to-period fluctuations in our business
and operating results due to general industry conditions.

                                       9
<PAGE>
INTENSE COMPETITION IN THE SEMICONDUCTOR INDUSTRY MAY REDUCE THE DEMAND FOR OUR
PRODUCTS OR THE PRICES OF OUR PRODUCTS, WHICH COULD REDUCE OUR REVENUE.

    The semiconductor industry is intensely competitive. Our competitors include
Cypress Semiconductor, Integrated Circuit Systems, Motorola, Pericom
Semiconductor, Philips Semiconductor and Texas Instruments. Most of these
competitors have substantially greater financial, technical, marketing,
distribution and other resources, broader product lines and longer-standing
customer relationships than we do. We also compete with other major and emerging
companies that sell products to certain segments of our markets. Competitors
with greater financial resources or broader product lines may have a greater
ability to sustain price reductions in our primary markets in order to gain or
maintain market share.

    We believe that our future success will depend on our ability to continue to
improve and develop our products and processes. Unlike us, many of our
competitors maintain internal manufacturing capacity for the fabrication and
assembly of semiconductor products. This ability may provide them with more
reliable manufacturing capability, shorter development and manufacturing cycles
and time-to-market advantages. In addition, some of our larger competitors who
have their own wafer fabrication facilities may be able to manufacture and sell
competitive products at lower prices. Any introduction of products by our
competitors that are manufactured with improved process technology could
seriously harm our business. As is typical in the semiconductor industry, our
competitors have developed and marketed products that function similarly or
identically to ours. If our products do not achieve performance, price, size or
other advantages over products offered by our competitors, our products may lose
market share. Competitive pressures could also reduce market acceptance of our
products, reduce our prices and increase our expenses.

OUR SUCCESS IS DEPENDENT ON THE GROWTH OF THE COMPUTING, COMMUNICATION AND
CONSUMER ELECTRONICS MARKETS AND OUR ABILITY TO MARKET AND SELL OUR INTEGRATED
CIRCUITS TO MANUFACTURERS SERVING THOSE MARKETS.

    In fiscal 1999, fiscal 2000 and the first quarter of fiscal 2001, we derived
a majority of our revenue from the sale of integrated circuits for applications
in the computing market, such as personal computers, notebook computers and
workstations. The computing market, and in particular the personal computer
industry, is subject to price competition, rapid technological change, evolving
standards, short product life cycles and continuous erosion of average selling
prices. Should the computing market decline or experience slower growth, a
decline in the order rate for our products could occur. We expect that sales of
our products for applications in the computing market, as well as applications
in the communications and consumer electronic markets, will account for a
significant portion of our revenues in the future. Our ability to market and
sell our integrated circuits to manufacturers in those markets will have a
significant impact on our financial performance for the foreseeable future. If
the markets for these products and applications decline or fail to develop as
expected or we are not successful in our efforts to market and sell our products
to manufacturers who incorporate integrated circuits into these products, our
financial results will be harmed.

PRODUCT PRICE DECLINES AND FLUCTUATIONS MAY CAUSE OUR FUTURE FINANCIAL RESULTS
TO VARY.

    Historically, selling prices in the semiconductor industry generally, as
well as for our products, have decreased significantly over the life of each
product. We expect that selling prices for our existing products will continue
to decline over time and that average selling prices for our new products will
decline significantly over the lives of these products. Declines in selling
prices for our products would affect our revenue and, if not offset by
reductions in the costs of producing these products or by sales of new products
with higher gross margins, would reduce our overall gross margins and could
seriously harm our business.

                                       10
<PAGE>
WE ARE NOT PROTECTED BY LONG-TERM CONTRACTS WITH OUR CUSTOMERS, AND WE ALLOCATE
RESOURCES BASED ON OUR FORECASTS OF CUSTOMER DEMAND, WHICH COULD LEAD TO EXCESS
INVENTORY OR LOST REVENUE OPPORTUNITIES.

    We generally do not enter into long-term purchase contracts with our
customers, and we cannot be certain as to future order levels from our
customers. When we do enter into a long-term contract, the contract is generally
terminable at the convenience of the customer. In the event of an early
termination by one of our major customers, it is unlikely that we will be able
to rapidly replace that revenue source, which would harm our financial results.

    Our sales are generally made on the basis of purchase orders which may be
cancelled at any time by customers rather than long-term non-cancelable purchase
contracts, and we manufacture our products according to our estimates of
customer demand. This process requires us to make multiple demand forecast
assumptions, each of which may introduce error into our estimates. If we
overestimate customer demand, we may allocate resources to products that we may
not be able to sell or we may have to sell our products to other customers at
lower prices. As a result, we would have excess inventory, which would adversely
affect our financial results. Conversely, if we underestimate customer demand,
we may forego revenue opportunities or damage our customer relationships.

WE ARE DEPENDENT UPON OUR INTERNATIONAL SALES AND MANUFACTURING. ECONOMIC,
POLITICAL OR MILITARY EVENTS IN A COUNTRY OR REGION WHERE WE MAKE SIGNIFICANT
SALES OR OUTSOURCE SIGNIFICANT MANUFACTURING COULD HARM OUR BUSINESS.

    During fiscal 2000, approximately 75.2% of our total revenue was derived
from international sales. During the first quarter of fiscal 2001, approximately
72.5% of our revenue was derived from international sales. A substantial portion
of these international sales consist of sales to foreign subcontractors who
incorporate our integrated circuits into products for domestic systems
manufacturers. We anticipate that international sales will continue to represent
a significant portion of our total revenue for the foreseeable future. In
addition, a majority of our semiconductor products are manufactured, and
substantially all are assembled, outside of the United States by independent
foundries and subcontractors.

    We are subject to the risks inherent in doing business internationally,
including:

    - unexpected changes in regulatory requirements;

    - fluctuations in exchange rates;

    - political and economic instability;

    - imposition of tariffs and other barriers and restrictions; and

    - the burdens of complying with a variety of foreign laws.

    The occurrence of any of these events could harm our sales and financial
results.

    In addition, we are in the process of establishing a wholly-owned subsidiary
in Istanbul, Turkey where we intend to develop a design facility. We expect to
have several design engineers in this facility by the end of fiscal 2001 and
hope to continue to add personnel in the future. Any inability to manage, or
communicate effectively with, our design team in Turkey, could delay our
development efforts and divert our management's attention.

THE PRICES OF OUR PRODUCTS MAY BECOME LESS COMPETITIVE DUE TO FOREIGN EXCHANGE
FLUCTUATIONS.

    Foreign currency fluctuations may affect the prices of our products. Prices
for our products are currently denominated in U.S. dollars for sales to our
customers throughout the world. If there is a significant devaluation of the
currency in a specific country, the prices of our products will increase
relative to that country's currency and our products may be less competitive in
that country. Also, we

                                       11
<PAGE>
cannot be sure that our international customers will continue to be willing to
place orders denominated in U.S. dollars. If they do not, our revenue and
operating results will be subject to foreign exchange fluctuations.

OUR PRODUCTS GENERALLY HAVE LONG SALES CYCLES AND IMPLEMENTATION PERIODS, WHICH
INCREASES OUR COSTS IN OBTAINING ORDERS AND REDUCES THE PREDICTABILITY OF OUR
OPERATING RESULTS.

    Our products are technologically complex. Prospective customers generally
must make a significant commitment of resources to test and evaluate our
products and to integrate them into larger systems. As a result, our sales
process is often subject to delays associated with lengthy approval processes
that typically accompany the design and testing of new products. The sales
cycles of our products often last for many months. Longer sales cycles require
us to invest significant resources in sales and marketing prior to the
generation of revenue.

    Long sales cycles also subject us to other risks, including customers'
budgetary constraints, internal acceptance reviews and cancellations. In
addition, orders expected in one quarter could shift to another period due to
unforeseen delays in customers' purchase decisions. The time required for our
customers to incorporate our products into their own can vary significantly and
generally exceeds several months, which further complicates our planning
processes and reduces the predictability of our operating results.

IF WE ARE UNABLE TO OBTAIN AND MAINTAIN LICENSES OF KEY INTELLECTUAL PROPERTY
FROM THIRD PARTIES, THE QUALITY OF OUR PRODUCTS MAY BE AFFECTED AND, AS A
RESULT, OUR OPERATING RESULTS COULD BE HARMED.

    From time to time, we license technology from third parties to develop new
products or product enhancements. For example, we currently license technology
used in our EMI reduction products from Lexmark International. We may seek to
license additional intellectual property from third parties in the future. If we
are unable to obtain any third-party license required to develop new products
and product enhancements, or if a licensor should cease to support our licensed
technology, we may have to obtain substitute technology of lower quality or
performance standards or at greater cost, either of which could seriously harm
the competitiveness of our products.

OUR ABILITY TO COMPETE COULD BE JEOPARDIZED IF WE ARE UNABLE TO PROTECT OUR
INTELLECTUAL PROPERTY RIGHTS FROM CHALLENGES BY THIRD PARTIES.

    Our success and ability to compete depends in large part upon protecting our
proprietary technology. We rely on a combination of patent, trade secret,
copyright and trademark laws, non-disclosure and other contractual agreements
and technical measures to protect our proprietary rights. These agreements and
measures may not be sufficient to protect our technology from third-party
infringement, or to protect us from the claims of others. Monitoring
unauthorized use of our products is difficult and we cannot be certain that the
steps we have taken will prevent unauthorized use of our technology,
particularly in foreign countries where the laws may not protect our proprietary
rights as fully as in the United States. The laws of many foreign countries in
which our products are or may be developed, manufactured or sold, including
Turkey, where we are developing our own design center, and various countries in
Asia, where most of our subcontractors are located, may not protect our products
or intellectual property rights to the same extent as do the laws of the United
States and thus make the possibility of piracy of our technology and products
more likely in these countries. If competitors are able to use our technology,
our ability to compete effectively could be harmed.

                                       12
<PAGE>
WE COULD BECOME SUBJECT TO CLAIMS AND LITIGATION REGARDING INTELLECTUAL PROPERTY
RIGHTS, WHICH COULD SERIOUSLY HARM OUR BUSINESS AND REQUIRE US TO INCUR
SIGNIFICANT COSTS.

    In recent years, there has been significant litigation in the United States
involving patents and other intellectual property rights. In the past, we have
been subject to claims regarding alleged infringement of other parties'
intellectual property rights. We could become subject to litigation in the
future either to protect our intellectual property or as a result of allegations
that we infringe others' intellectual property rights. Claims that our products
infringe proprietary rights would force us to defend ourselves, and possibly our
customers or manufacturers, against the alleged infringement. These claims and
any resulting lawsuit, if successful, could subject us to significant liability
for damages, as well as invalidation of our proprietary rights. These lawsuits,
regardless of their success, would likely be time-consuming and expensive to
resolve and would divert management time and attention. Any potential
intellectual property litigation could force us to do one or more of the
following:

    - stop selling our products that incorporate the challenged intellectual
      property;

    - obtain a license to sell or use the relevant technology, which license may
      not be available on reasonable terms or at all;

    - pay damages; or

    - redesign those products that use the disputed technology.

If we are forced to take any of the foregoing actions, our business could be
severely harmed.

OUR PRODUCTS COULD CONTAIN DEFECTS, WHICH COULD REDUCE SALES OF THOSE PRODUCTS
OR RESULT IN CLAIMS AGAINST US.

    We develop complex products. Despite testing by us and our customers, errors
may be found in existing or new products. This could result in, among other
things, a delay in recognition or loss of revenue, loss of market share or
failure to achieve market acceptance. These defects may cause us to incur
significant warranty, support and repair costs, divert the attention of our
engineering personnel from our product development efforts and harm our
relationships with our customers. Defects, integration issues or other
performance problems in our products could result in financial or other damages
to our customers or could damage market acceptance of our products. Our
customers could also seek damages from us for their losses. A product liability
claim brought against us, even if unsuccessful, would likely be time consuming
and costly to defend. The occurrence of these problems would likely harm our
business.

WE DEPEND UPON KEY MANAGEMENT AND THE LOSS OF CERTAIN KEY MEMBERS OF MANAGEMENT
COULD NEGATIVELY IMPACT OUR BUSINESS PROSPECTS.

    Our future success is substantially dependent on the continued services and
continuing contributions of our senior management and other key personnel,
particularly Ilhan Refioglu, our President and Chief Executive Officer, and
Gregory J. Richmond, our Vice President, Engineering and Chief Technology
Officer. Loss of the services of any of our executive officers or other key
employees could harm our business. We have no long-term employment agreements
with any of our key personnel other than Dr. Refioglu, whose employment
agreement expires in September 2000 but is automatically renewable for one-year
terms unless either party elects not to renew the agreement. We do not maintain
key person life insurance on any of our key employees.

                                       13

BECAUSE OF INTENSE COMPETITION FOR TECHNICAL AND MANAGERIAL PERSONNEL, WE MAY
NOT BE ABLE TO RECRUIT OR RETAIN NECESSARY PERSONNEL, WHICH COULD HARM OUR
BUSINESS.

    We are dependent upon our ability to attract and retain highly-skilled
technical and managerial personnel. We believe that our future success in
developing marketable products and achieving a competitive position will depend
in large part upon whether we can attract and retain skilled personnel.
Retention of scientific and engineering personnel in our industry typically
requires us to present attractive compensation packages, including stock option
grants. Competition for such personnel is intense, particularly in the Silicon
Valley, and there can be no assurance that we will be successful in attracting
and retaining the personnel we require to successfully develop new and enhanced
products and to continue to grow and operate profitably.

WE MAY MAKE ACQUISITIONS WHICH COULD SUBJECT US TO A NUMBER OF OPERATIONAL
RISKS.

    In order to grow our business and maintain our competitive position, we may
acquire other businesses in the future. We cannot predict whether or when any
acquisitions will occur, and we cannot assure you that any acquired business
will be successfully integrated into our operations or will perform as we
expect. Any future acquisitions could involve risks, including the assumption of
additional liabilities and diversion of management's attention from other
business concerns. Furthermore, we may issue equity securities or incur debt to
pay for any future acquisitions. If we issue equity securities, your percentage
ownership of our company would be reduced. We may also enter into joint venture
transactions. Joint ventures have the added risk that the other joint venture
partners may have economic, business or legal interests or objectives that are
inconsistent with our interests and objectives. We may also have to fulfill our
joint venture partners' economic or other obligations if they fail to do so. If
we are unable to integrate any future acquisitions into our operations
successfully, our business could be harmed.

OUR OPERATIONS AND FINANCIAL RESULTS COULD BE SEVERELY HARMED BY NATURAL
DISASTERS.

    Our headquarters and some of our major suppliers' manufacturing facilities
are located near major earthquake faults. One of the assembly subcontractors we
use is located in Taiwan, which recently suffered a severe earthquake. We did
not experience significant disruption to our operations as a result of that
earthquake. However, if a major earthquake or other natural disaster were to
affect our operations or those of our suppliers, our business would be seriously
harmed.

A SIGNIFICANT PORTION OF THE NET PROCEEDS OF THIS OFFERING WILL BE USED TO REPAY
INDEBTEDNESS, AND MANAGEMENT WILL HAVE BROAD DISCRETION OVER THE USE OF THE
REMAINDER OF THE PROCEEDS.

    We expect to use a significant portion of the net proceeds of this offering
to repay indebtedness totaling approximately $5.7 million and to redeem
preferred stock owned by TA Associates and its related investment funds for
$12.4 million. As a result, the full amount raised in this offering will not be
available to fund our future operations. We may require additional equity or
debt financing to meet our working capital requirements or to fund our research
and development efforts. There can be no assurance that additional financing
will be available when required or, if available, will be on terms satisfactory
to us. Our management will have broad discretion in determining how to spend the
remainder of the net proceeds from this offering and may spend the proceeds in a
manner that our stockholders may not deem desirable. We cannot assure you that
our investments and use of the net proceeds of this offering will yield
favorable returns or results.

                                       14
<PAGE>
INVESTMENT FUNDS AFFILIATED WITH TA ASSOCIATES WILL OWN A MAJORITY OF OUR
OUTSTANDING STOCK UPON COMPLETION OF THIS OFFERING AND, AS A RESULT, CAN CONTROL
THE ELECTION OF OUR BOARD OF DIRECTORS AND THE OUTCOME OF MOST ISSUES SUBMITTED
TO OUR STOCKHOLDERS.

    Upon completion of this offering, investment funds affiliated with TA
Associates will hold, in the aggregate, approximately   % (or   % if the
underwriters' over-allotment option is exercised) of our outstanding common
stock. In addition, two of the directors that will serve on our board following
this offering will be representatives of TA Associates. By virtue of such stock
ownership, these investment funds, acting alone, can control most matters
submitted to our stockholders, including the election of our directors, and will
continue to exercise control over our business, policies and affairs. This
concentration of voting power could have the effect of delaying, deterring or
preventing a change of control of our company or other business combination that
might otherwise be beneficial to our stockholders.

DELAWARE LAW AND OUR CHARTER DOCUMENTS CONTAIN PROVISIONS THAT COULD DISCOURAGE
OR PREVENT A POTENTIAL TAKEOVER, EVEN IF SUCH A TRANSACTION WOULD BE BENEFICIAL
TO OUR STOCKHOLDERS.

    Some provisions of our Certificate of Incorporation and Bylaws, as well as
provisions of Delaware law, may discourage, delay or prevent a merger or
acquisition that a stockholder may consider favorable. These provisions include:

    - authorizing the board to issue additional preferred stock;

    - prohibiting cumulative voting in the election of directors;

    - limiting the persons who may call special meetings of stockholders;

    - prohibiting stockholder actions by written consent; and

    - establishing advance notice requirements for nominations for election to
      the board of directors or for proposing matters that can be acted on by
      stockholders at stockholder meetings.

A SUBSTANTIAL NUMBER OF SHARES OF OUR COMMON STOCK WILL BECOME AVAILABLE FOR
SALE IN THE PUBLIC MARKET SIMULTANEOUSLY, WHICH COULD CAUSE THE MARKET PRICE OF
OUR STOCK TO DECLINE.

    Sales of a substantial number of shares of our common stock in the public
market following this offering, or the fact that a large number of shares
simultaneously will become available for sale, could cause the market price of
our common stock to decline. The number of shares of common stock available for
sale in the public market will be limited by lock-up agreements under which the
holders of substantially all of our outstanding shares of common stock and
options to purchase common stock will agree not to sell or otherwise dispose of
any of their shares for a period of 180 days after the date of this prospectus
without the prior written consent of Wit SoundView Corporation. Upon the
expiration of these lock-up agreements and assuming the full exercise of all
vested options to purchase common stock outstanding on June 30, 2000,
approximately       shares of common stock will become eligible for sale
simultaneously. Moreover, Wit SoundView Corporation may, in its sole discretion
and at any time without notice, release all or any portion of the securities
subject to lock-up agreements. In addition to the adverse effect a price decline
could have on holders of our common stock, such a decline would likely impede
our ability to raise capital through the issuance of additional shares of common
stock or other equity securities.

YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION IN THE NET TANGIBLE BOOK
VALUE OF THE STOCK YOU PURCHASE.

    The initial public offering price of our common stock will be substantially
higher than the pro forma net tangible book value per share of the outstanding
common stock immediately after the

                                       15
<PAGE>
offering. Therefore, based on an estimated initial public offering price of
      per share, if you purchase our common stock in this offering you will
suffer immediate dilution of approximately       per share. If additional shares
are sold by the underwriters following exercise of their over-allotment option,
or if outstanding options or warrants for our common stock are exercised, there
will be further dilution.

OUR STOCK PRICE MAY BE VOLATILE AND YOU MAY BE UNABLE TO RESELL YOUR SHARES AT
OR ABOVE THE OFFERING PRICE.

    There previously has not been a public market for our common stock. We
cannot predict the extent to which investor interest in us will lead to the
development of a trading market or how liquid that market might become. The
initial public offering price for our common stock was determined by
negotiations between us and the representatives of the underwriters and may not
be indicative of prices that will prevail in the trading market. In addition,
the stock market in general, and the Nasdaq National Market and stocks of
technology companies in particular, have experienced extreme price and volume
fluctuations. This volatility is often unrelated or disproportionate to the
operating performance of these companies. Broad market and industry factors may
adversely affect the market price of our common stock, regardless of our actual
operating performance. In the past, following periods of volatility in the
market price of a company's securities, securities class-action litigation has
often been initiated against the company. This type of litigation, if initiated
against us, could result in substantial costs and a diversion of management's
attention and resources, which would significantly harm our business.

                           FORWARD-LOOKING STATEMENTS

    Statements under "Prospectus Summary," "Risk Factors," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business" and elsewhere in this prospectus about our future plans and
intentions, results, levels of activity, performance, goals or achievements or
other future events constitute forward-looking statements. These statements
involve known and unknown risks, uncertainties and other factors that may cause
actual results or events to differ materially from those anticipated in our
forward-looking statements. These factors include, among others, those listed
under "Risk Factors" or described elsewhere in this prospectus.

    In some cases, you can identify forward-looking statements by our use of
words such as "may," "will," "should," "could," "would," "expects," "plans,"
"intends," "anticipates," "believes," "estimates," "predicts," "potential" or
"continue" or the negative or other variations of these words, or other
comparable words or phrases.

    Although we believe that the expectations reflected in our forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements or other future events. We are under no
obligation to update any of our forward-looking statements after the date of
this prospectus. You should not place undue reliance on forward-looking
statements.

                                USE OF PROCEEDS

    We estimate our net proceeds from the sale of the         shares of common
stock offered by us in this offering to be approximately $    million, or
approximately $    million if the underwriters exercise their over-allotment
option in full, based on an assumed initial public offering price of $    per
share and after deducting the estimated underwriting discount and offering
expenses. We will not receive any of the proceeds from the sale of shares by the
selling stockholders.

    We intend to use the net proceeds of this offering:

    - to repay outstanding principal of approximately $3.2 million and accrued
      interest under a bank term loan and $2.5 million and accrued interest
      under a promissory note payable to a stockholder;

    - to redeem all outstanding shares of our Series A redeemable preferred
      stock for $12.4 million; and

    - for general corporate purposes, including capital expenditures and working
      capital.

    We may also use a portion of the net proceeds to acquire or invest in
complementary businesses or products or to obtain the right to use complementary
technologies. However, we have no current commitments or agreements with respect
to any of these types of acquisitions or investments. Pending these uses, we
intend to invest the net proceeds from this offering in short-term,
investment-grade, interest-bearing securities.

    The term loan is payable in quarterly installments through December 2002 and
bears interest, at our election, at the bank's prime rate plus 0.5%, or the
LIBOR rate plus 2.0%. The interest rate on the term loan was 8.57% at June 30,
2000. The promissory note is payable upon the closing of this offering and bears
interest at the rate of 9.0% per annum.

                                DIVIDEND POLICY

    We have never paid cash dividends on our capital stock. We currently intend
to retain future earnings to finance the growth and development of our business,
and we do not anticipate paying any cash dividends in the foreseeable future. In
addition, the terms of our bank credit facility currently prohibit the payment
of dividends.

                                 CAPITALIZATION

    The following table sets forth our short-term debt and capitalization as of
June 30, 2000:

    - on an actual basis, assuming that our reincorporation in Delaware and a
      three-for-two stock split had taken place as of June 30, 2000;

    - on a pro forma basis, giving effect to the conversion of all outstanding
      shares of our mandatorily redeemable convertible preferred stock into an
      aggregate of 10,662,057 shares of common stock and 3,159,128 shares of
      Series A redeemable preferred stock;

    - on a pro forma basis, as further adjusted to reflect the sale by us of
            shares of common stock in this offering, at an assumed initial
      public offering price of $      per share after deducting the estimated
      underwriting discount and offering expenses, and our receipt and
      application of the net proceeds.

                                    DILUTION

    The pro forma net tangible book value (deficit) of our common stock as of
June 30, 2000 was approximately $(13.0) million, or $(0.85) per share. Pro forma
net tangible book value (deficit) per share represents the amount of our total
assets, excluding net intangible assets, less our total liabilities, divided by
the total number of shares of common stock outstanding, after giving effect to
the conversion of all outstanding shares of our mandatorily redeemable
convertible preferred stock into an aggregate of 10,662,057 shares of common
stock and 3,159,128 shares of Series A redeemable preferred stock, and the
redemption of all outstanding shares of Series A redeemable preferred stock.
Dilution in pro forma net tangible book value per share represents the
difference between the amount per share paid by investors in this offering and
the pro forma net tangible book value per share of our common stock immediately
after the offering. After giving effect to the sale by us of       shares of
common stock in this offering, at an assumed initial public offering price of
$      per share, and after deducting the estimated underwriting discount and
offering expenses payable by us, the pro forma net tangible book value of our
common stock would have been $      million, or $      per share. This
represents an immediate increase in net tangible book value of $      per share
to existing stockholders and an immediate dilution of $      per share to new
investors. The following table illustrates this per share dilution:

    You should read the following selected consolidated financial data in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and our consolidated financial statements and the
notes thereto included elsewhere in this prospectus. The consolidated statement

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    THE FOLLOWING DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE
RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS COULD DIFFER SUBSTANTIALLY FROM
THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF MANY
FACTORS, INCLUDING THOSE SET FORTH UNDER "RISK FACTORS" AND ELSEWHERE IN THIS
PROSPECTUS. THE FOLLOWING DISCUSSION SHOULD BE READ TOGETHER WITH OUR
CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES THERETO INCLUDED ELSEWHERE
IN THIS PROSPECTUS.

OVERVIEW

    We design, develop and market high performance integrated circuits for the
computing, communications and consumer electronics markets. We were founded in
1972 as a supplier of semi-custom gate-array integrated circuits. In 1991, we
entered the timing device market. We introduced our first EMI reduction circuits
in 1994, our first zero delay buffers in fiscal 2000, and our initial line of
high performance logic integrated circuits in fiscal 2001.

    In 1997, we decided to focus our efforts on establishing a leadership
position in the timing device market and discontinued production of semi-custom
gate-array integrated circuits. At that time, we also decided to outsource all
wafer fabrication to independent foundries and discontinued operation of our own
wafer fabrication facility. All fixed assets related to our wafer fabrication
facility were sold, and a $1.4 million loss on the transaction was recorded in
fiscal 1998.

    In December 1997, we recapitalized our company, resulting in a group of
investors, led by TA Associates, acquiring a 92% equity interest in our company.
In connection with this recapitalization, we received $13.8 million in net
proceeds from the sale of equity securities and incurred indebtedness of
$15.0 million. An aggregate of 15,896,250 shares out of a total of 17,212,500
outstanding shares of common stock held by our founder were redeemed for
$24.3 million, $21.8 million of which was paid in cash and $2.5 million of which
was paid by issuance of a promissory note. Our founder retained an 8% equity
interest in our company. The recapitalization was accounted for as a leveraged
recapitalization such that our assets and liabilities remain at their historical
bases for financial reporting purposes. For income tax purposes, the transaction
was treated as a taxable business combination such that the financial statements
reflect a "step-up" in tax basis. We recorded a $5.3 million stock-based
compensation charge in fiscal 1998 primarily related to the repurchase of
outstanding stock options in connection with the recapitalization.

    In July 1998, we disposed of land and a building with a net book value of
$2.8 million. We recorded a gain of $3.0 million on the disposal of this
property. We subsequently leased the land and building from the buyer and
deferred the gain on sale, which is being recognized ratably over the seven-year
term of the lease. We recognized $436,000 of the gain during fiscal 2000.

    We derive all of our revenue from the sale of our integrated circuit
products. We sell our products through our direct sales force and indirectly
through distributors and manufacturers' representatives. Revenue from product
sales to original equipment manufacturers and from sales to distributors who
have no, or limited, product return rights and no price protection rights, is
recognized upon shipment, net of allowances for estimated returns. When
distributors have product return or price protection rights, we defer revenue
recognition until the time the distributor sells the product to the end
customer.

    Our international revenue was 69.3%, 80.5% and 75.3% of our total revenue
for fiscal 1998, 1999 and 2000, respectively, and 72.5% for the three months
ended June 30, 2000. All of our sales are denominated in U.S. dollars. A
substantial portion of this international revenue consists of sales to foreign
contract manufacturers and assemblers who incorporate our integrated circuits
into products for domestic systems manufacturers. We expect that revenue derived
from shipments to international

                                       22
<PAGE>
customers will continue to represent a significant and growing portion of our
total revenue. During fiscal 2000, sales of our products to Apple, Dell and IBM,
directly and through distributors and contract manufacturers, accounted for
22.7%, 19.6% and 12.4%, respectively, of our revenue. During the quarter ended
June 30, 2000, sales to Apple, Dell and Sanyo accounted for 19.4%, 21.0% and
10.6%, respectively, of our revenues. A significant percentage of our sales are
made to distributors and to contract manufacturers and assemblers who
incorporate our integrated circuits into products for systems manufacturers,
including Apple and Dell. Natsteel Electronics, a contract manufacturer,
accounted for 18.8% of our revenue in fiscal 2000. Natsteel Electronics, Global
Electronics, one of our Japanese distributors, and Jabil Circuit, another
contract manufacturer, accounted for 14.6%, 12.0% and 10.7%, respectively, of
our revenue in the quarter ended June 30, 2000.

    Historically, average selling prices in the semiconductor industry
generally, and for our products, have decreased over the life of a particular
product. We attempt to maintain gross margins as average selling prices decline
through the introduction of new products with higher margins and through
manufacturing efficiencies and cost reductions. We believe that as our product
lines continue to mature and competitive markets evolve, we are likely to
experience further declines in the average selling prices of our products,
although we cannot predict the timing and amount of such future changes with any
certainty.

    Our cost of revenue consists primarily of fabrication costs, assembly and
test costs, costs of materials and overhead from operations. We outsource all
our fabrication and assembly operations and a small percentage of our final test
operations. Accordingly, a significant portion of our cost of revenue consists
of payments to our contract manufacturers. We conduct supply chain management,
assembly engineering, quality assurance and documentation control at our
facility in Milpitas, California. There can be no assurance that we will be able
to reduce our cost of revenue to keep pace with anticipated decreases in average
selling prices.

    Our gross profit margins vary among our product families. Generally, our
gross margins are higher on our EMI reduction integrated circuits and zero delay
buffers than on our clocks. We expect that our overall gross margins will
fluctuate from period to period as a result of shifts in product mix,
anticipated decreases in average selling prices and our ability to reduce
product costs.

    Research and development expenses consist primarily of salaries and related
expenses for design engineers and other technical personnel, the cost of
developing prototypes and fees paid to consultants. We charge all research and
development expenses to operations as incurred. We believe that continued
investment in research and development is critical to our long-term success.
Accordingly, we expect that our research and development expenses will increase
in absolute dollars in future periods.

    Selling expenses consist primarily of sales commissions, salaries and
related expenses for personnel engaged in sales, marketing and field support
activities, and other costs associated with the promotion of our products. We
intend to pursue aggressive selling and marketing campaigns and to expand our
direct sales organization. We therefore expect that our selling expenses will
increase in absolute dollars in future periods. General and administrative
expenses consist primarily of salaries and related expenses for administrative
and finance personnel, professional fees and other corporate expenses. We expect
that, in support of our continued growth and our operations as a public company,
general and administrative expenses will continue to increase in absolute
dollars in the foreseeable future.

    In connection with the grant of stock options to employees between April 1,
1999 and June 30, 2000, we recorded deferred stock-based compensation of
$3.6 million in fiscal 2000 and $2.1 million in fiscal 2001, representing the
difference between the deemed value of our common stock for accounting purposes
and the option exercise price of these options at the date of grant. Deferred
stock-based compensation is presented as a reduction of stockholders' equity,
with accelerated amortization recorded over the vesting period which is
typically four years. We amortized $974,000 and $689,000 of deferred stock-based
compensation during fiscal 2000 and the three months ended June 30, 2000. The

                                       23
<PAGE>
amount of stock-based compensation expense to be recorded in future periods
could decrease if options for which accrued but unvested compensation has been
recorded are forfeited.

THREE MONTHS ENDED JUNE 30, 2000 COMPARED TO THREE MONTHS ENDED JUNE 30, 1999

    NET REVENUE.  Net revenue increased by 9.4% to $11.5 million in the three
months ended June 30, 2000 from $10.5 million in the same period in 1999. The
increase in net revenue was the result of increased unit sales of our products
due to new product design wins and customer applications, offset by a slight
decrease in average selling prices. We expect that average selling prices will
continue to decline in the near term until sales volumes of our new
higher-margin products increase.

    GROSS PROFIT.  Gross profit increased by 23.5% to $5.6 million in the three
months ended June 30, 2000 from $4.5 million in the same period in 1999. Gross
margin increased to 48.4% in the three months ended June 30, 2000 compared to
42.9% in the same period in 1999. The increase was due to a shift in product mix
to our higher-margin EMI reduction integrated circuits and zero delay buffer
products and to lower per unit manufacturing costs. Gross profit for the three
months ended June 30, 2000 excludes $60,000 of stock-based compensation.

    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
increased by 34.1% to $2.1 million in the three months ended June 30, 2000 from
$1.6 million in the same period in 1999. The increase was primarily due to the
hiring of additional development personnel, an increase in fees paid to
consultants and increased prototyping costs. These increased expenditures were
primarily related to the development of new integrated circuit designs using
smaller manufacturing geometry and customizations. Research and development
expenses increased as a percentage of revenue to 18.6% in the three months ended
June 30, 2000, compared to 15.2% in the same period in 1999.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased by 23.7% to $1.8 million in the three months
ended June 30, 2000 from $1.5 million in the

                                       24
<PAGE>
same period in 1999. The increase was primarily due to increased sales and
marketing expenses related to the expansion of our direct international sales
force, the hiring of additional applications engineers and higher sales
commissions resulting from increased revenue.

    INTEREST AND OTHER INCOME (EXPENSE), NET.  Net interest and other income
(expense) was $95,000 in the three months ended June 30, 2000, compared to a net
expense of $181,000 in the same period in 1999. The improvement resulted
primarily from a decrease in the average balance of our outstanding
indebtedness.

    PROVISION FOR INCOME TAXES.  Our effective income tax rate was 75% and 55.5%
for the three month periods ended June 30, 2000 and June 30, 1999, respectively.
The effective rates were higher than our statutory rate due to the effect of
stock-based compensation charges.

FISCAL YEAR ENDED MARCH 31, 2000 COMPARED TO FISCAL YEAR ENDED MARCH 31, 1999

    NET REVENUE.  Net Revenue increased by 13.7% to $44.3 million in fiscal 2000
from $39.0 million in fiscal 1999. The increase in net revenue resulted
primarily from increased unit sales of our EMI reduction integrated circuits and
clocks and the introduction of our zero delay buffer product family in the
second half of fiscal 2000. These increased unit sales were offset slightly by a
decline in average selling prices.

    GROSS PROFIT.  Gross profit increased by 26.7% to $20.3 million in fiscal
2000 from $16.0 million in fiscal 1999. Gross margin increased to 45.7% in
fiscal 2000, compared to 41.0% in fiscal 1999. The increase was due to a shift
in product mix toward an increased percentage of higher-margin products,
including new clocks and zero delay buffers in fiscal 2000. Lower per unit
manufacturing costs also contributed to the improvement in gross margin. Gross
profit for the year ended March 31, 2000 excludes stock-based compensation of
$73,000.

    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
increased by 13.5% to $8.0 million in fiscal 2000 from $7.0 million in fiscal
1999. Research and development expenses increased as a result of planned
increases in headcount, consultants' fees and prototyping costs for the design
of new clocks and zero delay buffers. Research and development expenses remained
at 18.0% of revenue during fiscal 1999 and 2000.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased by 16.5% to $6.9 million in fiscal 2000 from
$5.9 million in fiscal 1999. The increase was primarily due to increased sales
and marketing expenses related to the expansion of our direct international
sales force, the hiring of additional applications engineers and higher sales
commissions resulting from increased revenue.

    INTEREST AND OTHER INCOME (EXPENSE), NET.  Interest expense was $773,000 in
fiscal 2000 compared to $1,098,000 in fiscal 1999. The improvement resulted
primarily from a decrease in the average balance of our outstanding
indebtedness.

    PROVISION FOR INCOME TAXES.  Our effective tax rate was 54% in fiscal 2000
compared to 51% in fiscal 1999. The effective rates were higher than our
statutory rate due to the effect of stock-based compensation charges.

FISCAL YEAR ENDED MARCH 31, 1999 COMPARED TO FISCAL YEAR ENDED MARCH 31, 1998

    NET REVENUE.  Net Revenue increased by 14.1% to $39.0 million in fiscal 1999
from $34.2 million in fiscal 1998. The increase in net revenue resulted
primarily from increased unit sales of our EMI reduction integrated circuits and
clocks as the result of the addition of new customers with multiple design wins,
partially offset by a decrease in average selling prices.

                                       25
<PAGE>
    GROSS PROFIT.  Gross profit increased by 12.3% to $16.0 million in fiscal
1999, from $14.2 million in fiscal 1998. Gross margin decreased to 41.0% in 1999
compared to 41.7% in 1998. The decrease was due to the decline in average
selling prices.

    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
increased by 43.2% to $7.0 million in fiscal 1999 from $4.9 million in fiscal
1998. The increase was due to increased headcount and prototype costs related to
the design of higher performance products. Research and development expenses
increased as a percentage of revenue to 17.9% in fiscal 1999 from 14.3% in
fiscal 1998.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased by 19.3% to $5.9 million in fiscal 1999 from
$5.0 million in fiscal 1998. The increase was due primarily to higher levels of
sales commissions and increased headcount in the marketing department.

    INTEREST AND OTHER INCOME (EXPENSE), NET.  Interest expense was
$1.1 million in fiscal 1999 compared to $800,000 in fiscal 1998. During fiscal
year 1999, interest expense increased due to an increase in the average balance
of our outstanding indebtedness.

    PROVISION FOR INCOME TAXES.  Our effective tax rate was 51% in fiscal 1999
compared to 36% in fiscal 1998. The tax benefit was the result of our net losses
in fiscal 1998.

    NET REVENUE.  Our quarterly operating results have been affected by seasonal
factors. Original equipment manufacturers that purchase our integrated circuits
for incorporation into personal computers and consumer electronics typically
increase their purchases during the pre-year-end holiday period. As a result,
our revenues have historically peaked in the second and third quarter of each
fiscal year and declined in the fourth quarter of the fiscal year. We expect
these seasonal fluctuations to continue for the foreseeable future. The
increases in quarterly revenue from one fiscal year to the next were primarily
due to increased unit shipments as the result of new customer design wins.

    GROSS PROFIT.  Gross margins improved in each quarter of fiscal 2000 over
the corresponding quarter in fiscal 1999 due to a shift in product mix toward
our higher-margin EMI reduction and zero delay buffer integrated circuits and to
reductions in per unit manufacturing costs. Gross margins have varied on a
sequential quarterly basis due to seasonal revenue levels and quarterly
fluctuations in product mix.

    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
increased over the nine-quarter period primarily due to the hiring of additional
development personnel and consultants and an increase in prototyping costs. The
high expenditures in the quarters ended December 31, 1998 and March 31, 2000
were due to unusually large numbers of prototypes delivered during those
quarters.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses fluctuate primarily as the result of sales commissions,
which are based on quarterly revenue. The unusually high expenditures in the
quarters ended March 31, 2000 and June 30, 2000 were related to the expansion of
our direct international sales force and the hiring of additional applications
engineers.

    We may experience a delay in generating or recognizing revenue for a number
of reasons. Orders at the beginning of each quarter typically do not equal
expected revenues for that quarter and are generally cancelable at any time.
Accordingly, we depend on obtaining orders in a quarter for shipment in that
quarter to achieve our revenue objectives. In addition, the timing of product
releases, purchase orders and product availability could result in significant
product shipments at the end of a quarter. Failure to ship these products by the
end of a quarter may adversely affect our operating results. Furthermore, our
customer agreements typically provide that the customer may delay scheduled
delivery dates and cancel orders within specified time frames without
significant penalty.

    Most of our expenses, such as employee compensation and lease payments for
facilities and equipment, are relatively fixed in the near term. In addition,
our expense levels are based in part on our expectations regarding future
revenues. As a result, any shortfall in revenue relative to our expectations
could cause significant changes in our operating results from quarter to
quarter. Our quarterly and annual operating results have fluctuated in the past
and are likely to fluctuate significantly in the future due to a variety of
factors, some of which are outside of our control. Due to the foregoing factors,
you should not rely on our quarterly revenue and operating results to predict
our future performance.

LIQUIDITY AND CAPITAL RESOURCES

    Since fiscal 1998 we have financed our operations through net cash flow from
our operations. At June 30, 2000, we had $4.7 million of cash and cash
equivalents and $6.5 million of working capital.

    Net cash provided by (used in) operating activities was $(2.3) million,
$4.9 million and $3.9 million in fiscal 1998, 1999 and 2000, respectively. The
net cash used in fiscal 1998 primarily represented our net loss and cash used to
finance our increases in accounts receivable and inventory. In fiscal 1999, net
income and an increase in accounts payable were the primary sources of cash from
operating activities. In fiscal 2000, net income and an increase in accrued
expenses and other liabilities, offset by a decrease in accounts receivable,
were the primary sources of cash from operating activities.

                                       28
<PAGE>
    Net cash provided by (used in) investing activities was $(1.0) million,
$5.1 million, and $(1.4) million in fiscal 1998, 1999 and 2000, respectively.
Net cash used in investing activities in fiscal 1998 and fiscal 2000 primarily
represented purchases of equipment for development activities. Net cash provided
by investing activities in fiscal 1999 primarily represented the proceeds from
the sale of our building. We intend to purchase approximately $2.0 million of
equipment to be used in development activities in fiscal 2001.

    Net cash provided by (used in) financing activities was $3.2 million, ($8.0)
million and $(1.7) million in fiscal 1998, 1999 and 2000, respectively. In
fiscal 1998, we sold preferred stock and incurred long-term debt to finance the
repurchase of 10,597,500 shares of outstanding common stock in conjunction with
our recapitalization. Net cash used for financing activities in fiscal 1999 and
2000 primarily represented principal payments on our long-term debt.

    We have a line of credit arrangement under a loan agreement with a bank
which allows for borrowings up to the lesser of $5.0 million or (i) 80% of our
net outstanding eligible accounts receivable balances, plus (ii) 50% of our net
outstanding eligible foreign accounts receivable, plus (iii) 100% of our net
outstanding eligible receivables supported by a letter of credit from a
financial institution. The loan agreement also includes a term loan arrangement.
Borrowings under our line of credit and our term loan bear interest, at our
election, at either the bank's prime rate, which was 9.5% at June 30, 2000, plus
0.5%, or the LIBOR rate, which was 6.57% at June 30, 2000, plus 2%. The line of
credit expires on December 16, 2002. There were no borrowings outstanding under
this line of credit arrangement at June 30, 2000.

    In connection with our recapitalization, we borrowed $15.0 million from a
bank under our term loan arrangement. The term loan is payable in quarterly
installments of principal and interest through December 2002. Debt issuance
costs of $325,000 are being amortized over the term of the term loan. During
fiscal 2000, we made principal payments on the term loan aggregating
$1.8 million, of which $900,000 were made in advance of the scheduled due date.
During the three month period ended June 30, 2000, the Company made principal
payments on the term loan aggregating $750,000, all of which were made in
advance of the scheduled due date (unaudited).

    We believe that the net proceeds from this offering, together with our
current balances of cash, anticipated cash flow from operations and borrowings
available under our line of credit will satisfy our anticipated working capital
and capital expenditure requirements for at least the next 12 months. After the
next 12 months, our capital and operating requirements will depend on many
factors, including the levels at which we maintain inventory and accounts
receivable, costs of securing access to adequate manufacturing capacity and
increases in our operating expenses.

    Additional capital may also be required for the consummation of any
acquisitions, businesses, products or technologies. To the extent that the funds
generated from this offering, together with existing resources and cash
generated from operations, are insufficient to fund our future activities, we
may need to raise additional funds through public or private financing or
borrowings. No assurance can be given than additional funds will be available or
that we can obtain funds on terms favorable to us.

QUANTITATIVE AND QUALITATIVE DISCLOSURE OF MARKET RISKS

  INTEREST RATE RISK

    Our cash and cash equivalents are exposed to financial market risk due to
fluctuation in interest rates, which may affect our interest income and the fair
market value of our investments. Due to the short maturities of our investments,
the carrying value approximates the fair value. In addition, we do not use our
investments for trading or other speculative purposes.

    We have performed an analysis to assess the potential effect of reasonably
possible near-term changes in interest and foreign currency exchange rates. The
effect of such rate changes is not expected

                                       29
<PAGE>
to be material to our results of operations, cash flows or financial condition.
All transactions to date have been denominated in U.S. dollars.

  FOREIGN CURRENCY EXCHANGE RISK

    Substantially all of our sales are denominated in U.S. dollars and as a
result, we have relatively little exposure to foreign currency exchange risk
with respect to any of our sales. We do not currently enter into forward
exchange contracts to hedge exposures denominated in foreign currencies or any
other derivative financial instruments for trading or speculative purposes.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued Statement on
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." SFAS No. 133 establishes a new model for accounting for
derivatives and hedging activities and supersedes and amends a number of
existing accounting standards. SFAS No. 133 requires that all derivatives be
recognized on the balance sheet at their fair market value, and that the
corresponding derivative gains or losses be either reported in the statement of
operations or as a deferred item depending on the type of hedge relationship
that exists with respect to such derivative. SFAS No. 133, as amended by SFAS
No. 137, "Accounting for Derivative Instruments and Hedging Activities--Deferral
of Effective Date of FASB Statement No. 133," is effective for all fiscal
quarters and years beginning after June 15, 2000. We do not currently have, or
plan to enter into, forward exchange contracts to hedge exposures denominated in
foreign currencies or any other derivative financial instruments for hedging,
trading or speculative purposes.

    In December 1999, the Securities and Exchange Commission (SEC) issued Staff
Accounting Bulletin No. 101 (SAB 101), "Revenue Recognition," which provides
guidance on the recognition, presentation and disclosure of revenue in financial
statements filed with the SEC. SAB 101 outlines the basic criteria that must be
met in order to recognize revenue and provides guidance for disclosures related
to revenue recognition policies. In June 2000, the SEC issued SAB 101B,
"Amendment: Revenue Recognition in Financial Statements" which extends the
effective date of SAB 101 to the fourth fiscal quarter of fiscal years
commencing after December 15, 1999. The SEC is preparing to issue interpretative
guidance relating to SAB 101, and the FASB continues to address revenue and
other related accounting issues. Our management believes that we are in
compliance with all of the rules and related guidance as they currently exist
related to SAB 101. However, any changes to generally accepted accounting
principles in these areas could impact the accounting for our operations.

    In March 2000, the Financial Accounting Standards Board issued
Interpretation No. 44, "Accounting for Certain Transactions Involving Stock
Compensation--An Interpretation of APB Opinion No. 25" (FIN 44). This
Interpretation clarifies the definition of employee for the purposes of applying
Accounting Practice Board Opinion No. 25, Accounting for Stock Issued to
Employees (APB 25), the criteria for determining whether a plan qualifies as a
noncompensatory plan, the accounting consequences of various modifications to
the terms of a previously fixed stock option or award and the accounting for an
exchange of stock compensation awards in a business combination. This
Interpretation is effective July 1, 2000, but certain conclusions in this
Interpretation cover specific events that occur after either December 15, 1998,
or January 12, 2000.

OVERVIEW

    We design, develop and market high performance integrated circuits for the
computing, communications and consumer electronics markets. Our product
portfolio includes timing devices and EMI reduction and high performance logic
integrated circuits. We believe our gate-array-based architecture, proprietary
input/output structures and extensive mixed-signal cell library enable us to
deliver flexible, high performance solutions to our customers faster than many
of our competitors, which in turn assists our customers in achieving their
time-to-market objectives. Our design methodology gives us fast design and
prototype cycle times and enables rapid new product introductions. We have
leveraged our design expertise to develop a portfolio of mixed signal silicon
platforms that can be quickly customized to produce different products in the

portfolio, as evidenced by our design wins with industry leading manufacturers,
including Apple, Canon, Cisco, Dell, Fujitsu Siemens, Hewlett Packard, IBM, NEC,
Panasonic, Pioneer, Sharp, Samsung, Sanyo, Sony and Xerox. For example, our
timing devices are designed into the Intel reference 815E mobile motherboard and
are referenced in the design reference guide for Intel 815E chipset-based
notebooks. In addition, we have earned design wins at Cisco, which have resulted
in the integration of our products into some of Cisco's leading edge routers. We
have also successfully penetrated the digital camera, DVD and minidisc player
market with recent design wins at Sanyo, Sony and Kenwood.

INDUSTRY BACKGROUND

  DEMAND FOR HIGH PERFORMANCE ELECTRONIC SYSTEMS

    Electronic systems play an increasingly important role in our lives, as
evidenced by the growth in personal computing, communications and consumer
electronics markets. The growth of these markets has been driven by the demand
for, and availability of, electronic systems characterized by ever-improving
performance, flexibility, reliability and functionality, as well as decreasing
size, cost and power consumption. In addition, the dramatic growth of the
Internet has resulted in consumer demand for greater bandwidth and higher speed.
These demands have resulted in both the development of new, and the enhancement
of existing, products in the computing, communications and consumer markets,
such as digital cameras, DVD players, game consoles, internet appliances,
network routers and switches, notebook computers and set-top boxes.

    Advances in integrated circuits and improvements in semiconductor technology
have contributed significantly to the increased performance of, and demand for,
these electronic systems. These advances have also enabled the continuing
transition from analog to digital systems. The performance of the components of
these systems, which include microprocessors, memory, logic, and timing devices,
must continue to improve in order to enable the continued development of higher
performance systems.

  THE COMPONENTS RESPONSIBLE FOR SYSTEM PERFORMANCE

    Electronic systems generate and manipulate electrical signals using
primarily four types of components:

    - control integrated circuits, such as microprocessors and controllers,
      which perform arithmetic and control functions;

                                       31
<PAGE>
    - memory integrated circuits, which store data and instructions for future
      retrieval;

    - logic integrated circuits, which control the transfering, buffering and
      routing of data; and

    - timing devices, which generate, buffer and distribute precise timing
      signals required to synchronize the operation of control and memory
      integrated circuits.

    While control and memory integrated circuits primarily consist of digital
circuits, integrated circuit timing devices and high performance logic typically
consist of digital and analog circuits, or mixed-signal circuits. Digital
circuits process discrete electrical signals in a binary format, while analog
circuits process continuous electrical signals over a specified range.
Mixed-signal circuits process both digital and analog signals on a single
integrated circuit to achieve higher levels of integration and enhanced
performance. The development of these mixed-signal integrated circuits
incorporates a level of circuit design complexity that presents significant
development challenges, requiring a high level of design expertise.

  THE ROLE OF TIMING DEVICES IN ELECTRONIC SYSTEMS

    Timing devices enable communication among the components within systems as
well as between systems. For proper communication between devices, their input
and output signals must be coordinated. Timing devices are often described as
providing the "heartbeat" of a system, as they generate the pulse by which all
the system's components coordinate their communication.

    Historically, the crystal oscillator has dominated the timing device market.
A crystal oscillator contains a piece of quartz that vibrates at a single and
fixed frequency, producing a timing signal. Although crystal oscillators can
meet the timing requirements of relatively simple electronic systems, they are
not ideally suited for many of the timing functions required in more complex
systems. For example, each crystal oscillator can generate only one base
frequency and, therefore, a separate crystal oscillator is required for each
base frequency generated within a system. Most complex systems, such as personal
computers, use multiple frequencies in their operation making the use of crystal
oscillators in such systems space and cost-prohibitive. Another shortcoming of
the crystal oscillator is that, in many applications, an additional integrated
circuit is required to amplify or multiply the oscillator signal. Furthermore,
crystal oscillators tend to become more expensive and less reliable at the
higher frequencies required by high performance systems.

    Over the last decade, the shortcomings of crystal oscillators have caused
the personal computing market to shift to the use of a type of integrated
circuit timing device known as a clock. A single clock can generate multiple
base frequencies, enabling the replacement of multiple crystals with a single
timing device, thereby lowering cost. Clocks also produce high quality signals
over a broad spectrum of frequencies, including the higher frequencies required
for high performance systems. Another benefit of clocks is their ability to
generate multiple copies of the same frequency while maintaining high signal
integrity. In addition, clocks provide frequency selection, which permits system
manufacturers to select the clock frequencies, thereby significantly reducing
system development time. As digital solutions become more pervasive, the same
transition from crystal oscillators to clocks that the computing market
experienced is now occurring in many other high volume applications, such as
digital cameras, DVD players, game consoles, internet appliances, network
routers and switches and set-top boxes.

    According to industry sources, the total market for clocks and crystal
oscillators is expected to grow from $2.8 billion in 1999 to over $3.8 billion
by 2001, an 18% compounded annual growth rate. In 1999, the market for clocks
was approximately $378 million, or 14% of the total market for clocks and
crystal oscillators. The market for clocks is expected to grow to over
$850 million, or 23% of the total market, by 2001, a 50% compounded annual
growth rate.

    Another category of timing device, the zero delay buffer, is an integrated
circuit that generates multiple outputs from a single input signal received from
a timing device without causing the delay

                                       32
<PAGE>
typically created when an electronic signal is transmitted through a system.
Zero delay buffers are increasingly being used in complex, high-speed systems
such as computer servers, workstations and networking systems, where data
transfers at optimum speeds are essential.

  THE ROLE OF HIGH PERFORMANCE LOGIC IN ELECTRONIC SYSTEMS

    Logic integrated circuits control the transfer, buffering and routing of
data between system components. Without a very high degree of precision in the
transfer, buffering and routing of electrical signals, the system either will
operate at a degraded performance level or crash. Systems with large memory and
energy efficiency requirements, such as computer servers and networking routers,
are increasingly requiring high performance, low-power buffering logic. These
products can be sold as complements to zero delay buffers in many applications.
According to Insight Onsite, this high performance buffering logic segment is
expected to grow from $370 million in 2000 to over $478 million by 2003.

  PERFORMANCE CHALLENGES

    Electronic system trends, including analog to digital conversion and
increasing performance and functionality, have driven the demand for high-speed,
high-performance integrated circuits to handle the transfer, routing, buffering
and timing of digital and analog signals, at high speeds with minimal loss of
signal quality. In order to meet the market demand for higher performance
systems, designers require integrated circuits that effectively address the
following performance issues:

    - PROPAGATION DELAY.  Propogation delay refers to the time required to
      transfer an electrical signal from a source to a destination. Long
      propagation delays create signal transfer bottlenecks and reduce system
      speed.

    - JITTER.  Jitter refers to the inevitable random fluctuations in the
      frequency and phase of signals. Excess jitter in a signal can cause a loss
      of data or a system crash.

    - SKEW.  Skew refers to the timing relation between the arrival of two or
      more signals at a designated place in the integrated circuit or system.
      The need to wait for all signals to arrive before a function can be
      performed results in added delay, and thus, lower system performance.

    - EMI.  EMI is a phenomenon that occurs when electromagnetic waves within
      systems interfere with other electronic signals. All operating circuits
      emit electromagnetic waves. EMI can impair system performance and
      interfere with electronic systems in close proximity.

  THE GROWING IMPORTANCE OF EMI

    High performance computing, communications and consumer electronics systems
operate at high frequencies and, as a result, emit elevated levels of EMI. These
high performance systems are also particularly susceptible to system disruption
due to incoming EMI. When EMI becomes too high at one frequency, it interferes
with communications systems using that frequency. Because EMI disrupts the
operations of cellular phones, televisions and other communications systems,
regulatory agencies worldwide place strict limitations on the peak emissions
allowed from any electronic device. For example, the Federal Aviation
Administration bans the use of computers and other electronic equipment during
take-offs and landings to prevent EMI from affecting avionics instruments.

    As a result of EMI regulation by the Federal Communications Commission,
manufacturers of electronic equipment must reduce EMI to remain in compliance
with governmental standards. Manufacturers have employed a variety of methods to
solve the EMI problem, such as the use of shielding material, most of which have
proven to increase end product size and weight and to be costly and time
consuming to deploy. Spread spectrum technology has become the EMI reduction
approach of choice because of its flexibility, ease of use and cost advantages.
This technique is used to modulate

                                       33
<PAGE>
the output frequency of a clock generator by a very small percentage, thus
reducing the peak energy generated by the occurrence of multiple signal
transitions without compromising the precision timing requirements of the
system.

  INDUSTRY DEMANDS

    In order to meet the demand for higher performance systems in the computing,
communications and consumer electronics markets, systems manufacturers require
high performance integrated circuits with programmable features that allow the
manufacturers to rapidly design and test systems, assisting them in meeting
their time-to-market and cost objectives. Due to both short design time and
limited product life cycles that these manufacturers face, they require
integrated circuit vendors to develop products rapidly and to deliver them in
volume. In addition, manufacturers need solutions that reduce the overall
footprint and cost of ownership of timing devices in their systems, while at the
same time, effectively handling some of the associated system performance issues
such as propagation delay, jitter, skew and EMI.

    Several major market trends have made system reliability at high frequency
and high data transfer rates even more challenging. System clock frequencies
have increased at a very rapid rate, shortening the time available to perform
data transfers. The increasing system-wide EMI emissions that result from
higher-frequency integrated circuits have compelled system designers to develop
and implement new ways to further reduce these emissions. These factors all
increase the need for very high performance timing, EMI reduction and logic
circuits with outstanding performance specifications. Integrated circuit vendors
are further required to accomplish these tasks in a cost-effective manner that
responds flexibly to specific customer needs.

to expand our sales, marketing and applications support organizations in order
to establish new customer relationships in our target markets.

                                       35
<PAGE>
    LEVERAGE CORE COMPETENCIES ACROSS MULTIPLE, HIGH GROWTH MARKETS.  Our
leading timing and EMI solutions have been and, we believe, will continue to be
a point of entry into high-growth markets. We believe that timing and EMI
solutions will increasingly be adopted in rapidly growing communications and
consumer products markets such as DVD players, digital cameras, game consoles,
internet appliances, network routers and switches and set-top boxes. In

expertise in producing high performance products to further penetrate leading
accounts, such as Cisco and Lucent in the communications market, Apple, Dell and
IBM in the computing market and Sanyo and Sony in the consumer market. We
believe that establishing accounts with these industry leaders will enable us to
attract other customers. Additionally, we target industry leaders like AMD, ATI,
Intel, nVidia and VIA that set the specifications for future system designs. We
work closely with these companies to be adopted into their reference platforms.
This enables broad acceptance of our products with leading manufacturers.

    CONTINUE TO EXPAND PRODUCT OFFERINGS.  We currently offer one of the most
extensive timing solutions in the industry and more EMI reduction products than
any of our competitors. We plan to continue to expand our portfolio by
developing new timing, EMI reduction and logic products and to transition
products over time to new product families and new manufacturing processes as
product performance requirements and process technologies evolve. Our design
methodology enables us to customize our products to individual system
requirements rapidly while enjoying the economies of scale of sharing the same
base die with numerous other products.

  CLOCKS

    Our clocks have jitter and skew performance that is typically well within
industry standard specifications. These products incorporate many features
including hard-wired and software controls for frequency selection, spread
spectrum modulation control, functional configuration, testability and power
controls. We have added registers and serial data interface to our clocks to
further increase functionality. All of our computer clocks include spread
spectrum technology to reduce EMI, and almost all have features to allow the
user to tune the amount of spread required for their particular system to meet
FCC regulations. Our clocks incorporate low noise output drivers to minimize
both the internal and external noise created by faster output edge rates. For
extremely high frequency architectures, we have optimized high-performance
differential outputs to produce clock outputs capable of running at frequencies
well in excess of the requirements of most current electronic systems.

  COMPUTING APPLICATIONS

    We develop products based on the specifications and requirements of Intel,
other manufacturers and major third party vendor requirements. This has led to
the development of over 50 products specifically designed for desktop and
high-performance computing applications. Due to the trend of

                                       37
<PAGE>
integrating more clocks into a single component, most hard-wired control
functions have been combined with output functionality utilizing dual mode pins.

    Notebook computer clocks require high precision clocks, programmability,
spread spectrum and other functional controls. Due to the need for low power
modes, these clocks tend to incorporate more features related to power control
and reduction, such as low frequency modes or various power down or sleep modes.
The clocks for these applications tend to be assembled in small pin count
packages, and tend to be offered in a smaller range of frequency combinations
and number of clock outputs. To address this market, we offer products that
operate at lower frequencies and within a smaller range of frequencies and are
assembled in packages with fewer pins.

  APPLICATION SPECIFIC CLOCKS

    We have worked directly with several key manufacturers to develop
application specific clocks for products such as digital cameras, DVD players,
game consoles and printers. After developing the product, we also offer these
clocks as standard products. These low skew, low jitter clocks incorporate a
subset of the features found in our computing clocks, and in general are offered
in smaller pin count packages.

  ZERO DELAY BUFFERS

    Leveraging our clock design expertise, we have developed a family of low
skew, programmable zero delay buffers. These devices accept an input reference
clock signal and then synchronize it with an output signal. Most of our zero
delay buffers have external feedback loops that give the user the ability to
adjust the input to output delays by loading or delaying the feedback signal.
Our zero delay buffers run at frequencies higher than most available in the
market today, with an operating range as wide as 10MHz to 150MHz.

  EMI REDUCTION INTEGRATED CIRCUIT

    One of our fastest growing products is EMI reduction integrated circuits. In
conjunction with these products, we have developed a variety of spread spectrum
techniques offering customers a choice in cost and EMI reduction performance.
Our EMI products provide the exact amount of EMI reduction required for
manufacturers' systems. Manufacturers can tune the amount of EMI reduction
required for their systems to meet FCC requirements with our programmable
integrated circuits. These products also include a frequency multiplication
function to eliminate the need for expensive higher order crystals.

  HIGH PERFORMANCE LOGIC INTEGRATED CIRCUITS

    To complement our zero delay buffers, we offer two families of high speed,
low skew 1.8 volt to 3.3 volt bus interface and back plane logic products, our
advanced low voltage CMOS, or AVC, and advanced very low voltage CMOS, or ALVC,
families. Our AVC family is composed of 16, 18, and 20 bit registers, latches,
buffers and transceivers and results in a typical propagation delay of one
nanosecond. We believe this is currently the fastest and lowest noise low
voltage transistor transistor logic, or LVTTA, compatible family available in
the market today. Our logic products operate over a wide temperature range,
making them robust enough for both commercial and industrial applications. Our
ALVC family meets older 3.3 volt specifications with typical propagation delays
of 3.5 nanoseconds, and serves the more mature logic market.

TECHNOLOGY

    Our key technological advantage lies in our ability to combine mixed-signal
integrated circuit design expertise with fast time-to-market architectures and
development tools. This technological

                                       38
<PAGE>
advantage enables us to produce clocks, zero delay buffers, EMI reduction
integrated circuits and high performance logic with leading edge performance.
Our design expertise, coupled with our proprietary gate-array design
methodology, has resulted in a portfolio of mixed signal silicon platforms that
can be quickly customized to produce different products in the last few
manufacturing steps without compromising performance.

  CLOCK CIRCUIT DESIGN

    At the core of each clock is a phase lock loop, or PLL, circuit consisting
of a high performance phase-detector, charge-pump, loop-filter, and voltage
control oscillator. This PLL generates a signal which it then manipulates with
frequency dividers and phase conditioning circuitry to produce one or more
copies of a particular timing signal. We believe our extensive development
effort has resulted in proprietary PLL circuitry with minimum sensitivity to
digital switching noise to produce timing signals with exceptionally low jitter
and skew. We believe our PLL technology enables us to provide superior clock
products for current and next generation electronic systems.

  GATE-ARRAY DEVELOPMENT METHODOLOGY

    We have developed a unique gate-array design methodology that provides
superior product configurability while maintaining performance and minimizing
cost. We have extensive experience in optimizing the individual gate geometry
and placement for best electrical performance, development speed and minimum
silicon area. Unlike the alternative standard cell and EPROM circuit
methodologies broadly employed in the industry, our design allows us to use any
transistor available, to efficiently change the type or quantity of logic
functions available and to change power supply configurations, which is critical
to controlling noise in mixed signal applications. We have made, and expect to
make, substantial investments in computer aided design tools required to
automate many of the development steps and to ensure accurate prediction of
silicon performance. This technology has enabled us to extend our gate-array
methodology to portions of the analog circuitry in proprietary transistor-arrays
which allows us to configure analog performance quickly.

  SILICON PLATFORM PORTFOLIO

    While our gate-array design methodology enables us to maximize the
utilization of digital devices, there remains a need to optimize analog devices
on the chip such as PLLs, logic gates, and input/ output pads. As a result, we
have developed a flexible analog design methodology that enables programming
using device interconnect layers which contain one, two or three PLLs and
associated logic and input/output pads. Configuring these platforms in the last
few steps of the CMOS process enables us to quickly meet the demanding
time-to-market requirements of today's high performance systems for both
prototype samples and full volume production.

  DESIGN FOR PROGRAMMABILITY

    Our extensive experience in designing timing products for various
applications enables us to design analog and digital circuits which are
electrically programmable to facilitate development of user configurable
products. This not only allows the user to quickly optimize the performance of
our products for their particular system, but also allows a particular product
to address a much wider market or customer base. Examples of design features
that allow users to electrically configure or "dial in" parameters include:

    - DIAL-A-DB--enables configuration of spread spectrum profiles, amplitudes,
      and modulation rates for optimum EMI reduction;

    - DIAL-A-FREQUENCY--enables configuration of output frequencies with fine
      resolution to maximize system performance;

                                       39
<PAGE>
    - DIAL-A-DRIVE--enables configuration of output buffer strengths to match
      board trace impedance for optimum signal integrity; and

    - DIAL-A-SKEW--enables configuration of output skews or delays relative to
      other generated or reference signals to provide optimum clock edge
      placement despite trace length or component tolerance mismatches on system
      boards.

  EMI REDUCTION

    We have developed and continue to develop cost-effective EMI reduction
integrated circuits that consume minimum silicon area and power. Our proprietary
and patented techniques provide for virtually unlimited user programmable spread
spectrum profiles, which are independent of operating frequency. This enables
users to optimize the operating speed of electronic systems while maintaining
full control of the amount of EMI reduction provided to meet regulatory
standards. The most common programmable spread spectrum profile used in our
products is the Lexmark profile which provides optimum EMI reduction for a given
modulation frequency and index. In addition to using spread spectrum techniques,
we have also developed proprietary and patented edge rate control circuits to
further minimize EMI.

  CLOCK AND LOGIC INPUT AND OUTPUT BUFFER DESIGN

    In addition to optimizing standard CMOS or transistor transistor logic level
input and output buffers for single ended clock reception and distribution, we
have extended our portfolio of proprietary and patented input/output buffers to
include those required for interface to today's high performance systems. These
include pseudo emitter coupled logic, series stub terminated logic for double
data rate memory applications, and several differential drivers required to
support the latest AMD Athlon systems, Intel Pentium 4 and Rambus. Significant
experience in clock distribution and logic interface has enabled engineering to
fine tune the models and design methodology used to optimize the performance of
input/output buffers with low jitter, skew, EMI, power consumption and ground
bounce. Each of the input/output buffers is designed using a transistor-array
that is common to every input/output pad, allowing optimization of product pin
locations and customization of input/output performance using only the upper
metal interconnect layers of the CMOS wafer process.

SALES, MARKETING AND TECHNICAL SUPPORT

    We sell our products primarily through our direct sales force and a
worldwide network of independent sales representatives. We sell our products in
Japan exclusively through distributors. We intend to expand our direct sales
organization as well as our sales representative and distributor channels. We
believe that our customers' purchase decisions are based on time to market,
performance, service and cost. Many of our customers have long relationships
with us based on our success in meeting these criteria. We believe that our
ability to respond rapidly to changes in demand for new or modified designs with
consistent high quality is a major factor in our success at sustaining customer
relationships.

    Our marketing efforts are focused on increasing brand name awareness and
identifying and developing customer opportunities. Key components of our
marketing efforts include targeting industry

                                       41
<PAGE>
leaders like AMD, ATI, Intel, nVidia and VIA that set the specifications for
future system designs. We work closely with these companies to be adopted in
their reference platforms. This adoption results in broad acceptance of our
products by other manufacturers. In addition, our marketing group provides
technical and strategic sales support to our direct sales personnel and sales
representatives including in-depth product presentations, technical manuals,
sales tools, pricing, marketing communications, marketing research, trademark
administration and other support functions.

    A high level of continuing service and support is critical to our objective
of developing long-term customer relationships. We emphasize customer service
and technical support in order to provide our customers and their end users with
the knowledge and resources necessary to successfully utilize our product line.
Our customer service utilizes a technical team of field and factory applications
engineers, technical marketing personnel and, when required, product design
engineers. We provide extensive customer support throughout the qualification
and sale process as well as on an ongoing basis.

    As of June 30, 2000, we employed 10 people in sales and marketing and seven
people in technical support.

MANUFACTURING

    We qualify and utilize third-party suppliers for the manufacture of silicon
wafers. Currently, all of our wafers are manufactured by Chartered
Semiconductor, IBM Microelectronics and Tower Semiconductor. These manufactured
wafers are packaged at five primary assemblers, and we have qualified at least
two additional assemblers for each package type. We agree with our suppliers on
production schedules based on order backlog and demand forecasts for the
approaching six month period.

    We test over 95% of our products at our Milpitas, California facility.
Currently, the remainder are tested at various third-party offshore testing
facilities. We do not expect to expand our testing facilities in Milpitas, and,
as a result, expect the percentage of our products tested by third parties
offshore to increase as we exceed the capacity of our domestic facilities.

RESEARCH AND DEVELOPMENT

    The design process for our products is extremely complex, involving the
development of a prototype through computer-aided design, the use of simulation
methodology, the generation of photo masks for the manufacturing process, the
fabrication of wafers and the characterization of the prototype on test systems
before submission to customers for qualification. Our research and development
efforts concentrate on the design and development of new leading-edge products
for our markets and the continued enhancement of our design capabilities. Over
the last three fiscal years, we have developed and introduced approximately 130
new products. We have developed libraries of proprietary mixed-signal integrated
circuit designs and have invested in extensive computer-aided design and
engineering resources specifically designed to support the increasing complexity
and customizable nature of our products. Investments in research and development
were approximately $4.9 million, $7.0 million and $8.0 million in fiscal 1998,
1999 and 2000, respectively. These expenses typically include costs for
engineering personnel, prototype costs, and the amortization of design tools and
support overhead related to new and existing product development. As of
June 30, 2000, our research and development staff consisted of 33 people.

    OPTION GRANTS DURING FISCAL 2000

    The following table sets forth information regarding grants of stock options
to each of the executive officers named in the Summary Compensation Table above
during the fiscal year ended March 31, 2000. All of these options were granted
under our 1997 equity compensation plan and are immediately exercisable, subject
to a right of repurchase by us which lapses at the rate of 20% one year from the
date of grant, an additional 20% two years from the date of grant and an
additional 1.67% per month for 24 months thereafter. The percentage of total
options set forth below is based on an aggregate of 553,200 options granted
during the fiscal year. All options were granted at the fair market value of our
common stock, as determined by the Board of Directors on the date of grant.
Potential realizable values are net of exercise price, but before taxes
associated with exercise. Amounts represent hypothetical gains that could be
achieved for the options if exercised at the end of the option term.

EMPLOYMENT CONTRACT

    In December 1997, we entered into an employment agreement with Ilhan
Refioglu, our President and Chief Executive Officer. The initial term of the
agreement ended in September 1999; however the agreement provides for successive
one-year extensions of the term thereafter unless either party elects not to
renew the agreement. The agreement fixes Dr. Refioglu's base salary at $280,000
per year and entitles him to such bonuses as the Board of Directors may award
from time to time, as well as other benefits provided to our other senior
executives. If we terminate Dr. Refioglu's employment other than for cause
(which is defined to include fraud, embezzlement, misappropriation or breach of
fiduciary duty against us, conviction of a felony or crime involving moral
turpitude, breach of the covenants of the agreement, or repeated failure to
perform his duties under the agreement), or if Dr. Refioglu voluntarily
terminates his employment following a significant diminution in his
responsibilities or power or a breach of the agreement by us that is not
promptly cured, Dr. Refioglu will be entitled to receive

                                       47
<PAGE>
his salary and benefits for one year, and payment for unpaid bonus and accrued
vacation, and all options which would have vested on or before two years from
the termination date shall vest.

STOCK PLANS

    As of June 30, 2000, 3,430,250 shares of common stock had been issued upon
exercise of options outstanding under our 1997 equity compensation plan and 1995
stock option plan. Options to purchase 1,793,748 shares of common stock, at a
weighted average exercise price of $0.54, were outstanding, and 3,691,000 shares
remained available for future grants. We do not expect to grant further options
under the 1995 stock option plan.

    1997 EQUITY COMPENSATION PLAN

    Our 1997 equity compensation plan was adopted by the Board of Directors and
approved by the stockholders in November 1997. We are authorized to issue up to
5,540,437 shares of common stock under this plan. This number of shares will be
increased on April 1, 2001 and each subsequent April 1 during the term of the
plan by 5% of the number of shares of common stock issued and outstanding on the
immediately preceding March 31. The 1997 equity compensation plan is
administered by the Board of Directors or by a committee of the Board, who
determine, consistent with the provisions of the plan, the persons to whom
awards are granted and all of the terms and conditions of awards. The
administrator has the authority to construe and interpret the terms of the plan
and awards granted under it and to amend or terminate the plan, subject to
stockholder approval of any amendment increasing the maximum number of shares
issuable under the plan or as otherwise required by law. Generally, no amendment
or termination may adversely affect any outstanding award without the consent of
the affected participant. Unless terminated sooner by the Board of Directors,
the plan will terminate automatically on November 19, 2007, the tenth
anniversary of its adoption by the Board.

    The plan authorizes grants of awards in the form of incentive stock options,
within the meaning of Section 422 of the Internal Revenue Code, nonstatutory
stock options, restricted stock purchase rights and bonuses, and stock
appreciation rights. While incentive stock options, and stock appreciation
rights appurtenant to an incentive stock option, may be granted only to
employees, including officers and employee directors, all other awards may be
granted to employees, non-employee directors and consultants. Subsequent to the
listing date of the shares and the occurrence of a material modification to the
plan, the issuance of all shares reserved, the expiration of the plan, the first
shareholder meeting electing directors three years after the first registration
of an equity security, or another date required by Section 162(m) of the Code,
no participant under the plan shall be eligible to be granted options and stock
appreciation rights covering more than 1,687,500 shares of our common stock in
any 12 month period.

    The exercise price of incentive stock options granted under the 1997 equity
compensation plan must not be less than the fair market value of a share of
common stock on the date of grant. In the case of nonstatutory stock options,
the exercise price must not be less than 85% of the fair market value of a share
of common stock on the date of grant. With respect to any optionee who owns
stock representing more than 10% of the voting power of all classes of our
outstanding capital stock, the exercise price of any incentive stock option must
be equal to at least 110% of the fair market value of a share of the common
stock on the date of grant, and the term of the option may not exceed five
years. The terms of all other options may not exceed ten years. The aggregate
fair market value, determined as of the date of option grant, of the common
stock for which an incentive stock option may become exercisable for the first
time may not exceed $100,000 in any calendar year. However, an incentive stock
option or a nonstatutory stock option may be granted with an exercise price
lower than that set forth above if such option is granted pursuant to an
assumption or substitution for another option in a manner satisfying the
provisions of Section 424(a) of the Code. In addition, the plan authorizes the
administrator to include as part of an option agreement a provision entitling an
optionee

                                       48
<PAGE>
to a further option, a re-load option, if the optionee exercises an option by
surrendering other shares of our common stock. The administrator has the
discretion to determine the vesting provisions and exercise requirements, if
any, of all options granted under the plan.

    Awards of restricted stock may be made under the 1997 equity compensation
plan either in the form of a restricted stock purchase right or a restricted
stock bonus. Restricted stock purchase rights are exercisable at prices
determined by the administrator, provided the purchase price per share must be
at least 85% of the fair market value of a share of common stock on the date the
award is made, while restricted stock bonuses are granted in consideration of
services rendered to us. Awards of restricted stock may be made subject to
vesting restrictions and other conditions as established by the administrator
and are not transferable by the participant until vested. Vesting may be based
on the participant's continued service with us. While the participant will have
voting rights and the right to receive dividends or other distributions paid
with respect to the restricted stock, any dividends or distributions paid in
stock are subject to the same vesting restrictions as the original award. Unless
otherwise provided by the administrator, if a participant's service terminates
for any reason, the participant will forfeit any then unvested shares acquired
as a restricted stock bonus, and we will have the option to repurchase for the
amount of the participant's original purchase price any then unvested shares
acquired by exercise of a restricted stock purchase right.

    The administrator may grant stock appreciation rights under the 1997 equity
compensation plan in the form of tandem stock appreciation rights, concurrent
stock appreciation rights or independent stock appreciation rights. Tandem stock
appreciation rights and concurrent stock appreciation rights are granted
pursuant to an option and are subject to the same terms and conditions
applicable to such option. Independent stock appreciation rights are granted
independent of any option and are subject to the same terms and conditions
applicable to nonstatutory stock options.

    The plan provides that in connection with a change in control, if the
acquiring corporation fails to assume the plan's outstanding awards or replace
them with substantially equivalent new awards, all awards will become
immediately exercisable in full. Any award not assumed by the acquiring
corporation or exercised prior to a change in control will terminate upon the
change in control. In addition, the plan allows the administrator to provide in
any award agreement full acceleration of the exercisability of the award if,
within 18 months following a change in control, the participant is
"involuntarily terminated without cause" or is "constructively terminated."

    1995 STOCK OPTION PLAN

    Our 1995 stock option plan was adopted by the Board of Directors and
approved by the stockholders in March 1995. We are authorized to issue up to
3,375,000 shares of common stock under this plan. The 1995 stock option plan is
administered by the Board of Directors or by a committee of the Board, who
determine, consistent with the provisions of the plan, the persons to whom
awards are granted and all of the terms and conditions of awards. The
administrator has the authority to construe and interpret the terms of the plan
and awards granted under it and to amend or terminate the plan, subject to
stockholder approval of any amendment increasing the maximum number of shares
issuable under the plan or as otherwise required by law. Generally, no amendment
or termination may adversely affect any outstanding award without the consent of
the affected participant. Unless terminated sooner by the Board of Directors,
the 1995 stock option plan will terminate automatically on the tenth anniversary
of its adoption by the Board.

    The 1995 stock option plan allows grants of incentive stock options to
employees, including officers and employee directors. In addition, it allows
grants of nonstatutory options to employees, nonemployee directors and
consultants. No employee may be granted options to purchase more than 2,025,000
shares in any one fiscal year; however, an employee may be granted options up to
an additional 2,025,000 shares in connection with the optionee's initial
employment.

                                       49
<PAGE>
    The exercise price of incentive stock options granted under the 1995 stock
option plan must not be less than the fair market value of a share of common
stock on the date of grant. In the case of nonstatutory stock options, the
exercise price must not be less than 85% of the fair market value of a share of
common stock on the date of grant. With respect to any optionee who owns stock
representing more than 10% of the voting power of all classes of our outstanding
capital stock, the exercise price of any option must be equal to at least 110%
of the fair market value of a share of the common stock on the date of grant,
and the term of the incentive stock option may not exceed five years. The terms
of all other options may not exceed ten years. The aggregate fair market value
(determined as of the date of option grant) of the common stock for which an
incentive stock option may become exercisable for the first time may not exceed
$100,000 in any calendar year. The board or any committee administering the 1995
stock option plan has discretion to determine vesting schedules and exercise
requirements, if any, of all options granted under the plan.

    In the event of a merger with another corporation, the acquiring corporation
may assume the outstanding options or substitute new options. Any outstanding
options not assumed or substituted by the acquiring corporation shall terminate
as of the closing date of the merger. In the event of our dissolution or
liquidation, any outstanding options will terminate immediately prior to such
dissolution or liquidation.

    2000 EMPLOYEE STOCK PURCHASE PLAN

    Our 2000 employee stock purchase plan was adopted by the Board of Directors
and approved by the stockholders in September 2000. A total of 200,000 shares of
common stock are reserved for issuance under the plan. This plan, which is
intended to qualify under Section 423 of the Internal Revenue Code, will be
administered by the Board of Directors. Employees, including officers and
employee directors, are eligible to participate in the plan if they are employed
by us for more than 20 hours per week and have been so employed for at least
three months. The plan will be implemented during sequential six-month offering
periods, the first of which will commence on the effective date of this offering
and will terminate on March 31, 2001. After the effective date of this offering,
offering periods under the plan will generally begin on April 1 and October 1 of
each year.

    The employee stock purchase plan permits eligible employees to purchase our
common stock through payroll deductions, which may not exceed 15% of the
employee's base salary. Stock may be purchased under the plan at a price equal
to 85% of the fair market value of our common stock on either the first or the
last day of the offering period, whichever is lower. Employees may end their
participation in the offering at any time during the offering period, and
participation ends automatically on termination of a participant's employment
with us. Participants may not purchase shares of common stock having a value,
measured at the beginning of the offering period, greater than $25,000 in any
calendar year or more than a number of shares in any six-month offering period
determined by dividing $12,500 by the fair market value of a share of our common
stock at the beginning of the offering period.

401(K) PLAN

    Effective May 1, 1986, we adopted the International Microcircuits, Inc.
Employees Saving & Retirement Plan, or the 401(k) plan, which is intended to be
a tax-qualified defined contribution plan under Sections 401(a) and 401(k) of
the Internal Revenue Code of 1986, as amended. Under the terms of the 401(k)
plan, eligible employees may elect to contribute from 1% to 15% of their
compensation as salary deferral contributions to the 401(k) plan, subject to
certain statutorily prescribed limits ($10,500 for calendar year 2000). The
401(k) plan also permits, but does not require, us to make discretionary
employer contributions. Since April 1999, we have been making employer
contributions, based on quarterly operating profits, of up to 100% of a
participant's salary deferral contribution not to exceed 6% of each
participant's compensation. As a tax-qualified plan, contributions to the 401(k)
plan

                                       50
<PAGE>
are generally deductible by us when made, and are not taxable to participants
until distributed from the 401(k) Plan. Pursuant to the 401(k) plan,
participants may direct the trustees to invest their accounts in selected
investment options.

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY

    Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit this indemnification under
some circumstances for liabilities, including reimbursement for expenses
incurred, arising under the Securities Act.

    As permitted by the Delaware General Corporation Law, we have adopted
provisions in our certificate of incorporation which provide that our directors
shall not be personally liable for monetary damages to us or our stockholders
for a breach of fiduciary duty as a director, except liability for:

    - a breach of the director's duty of loyalty to us or our stockholders;

    - acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law;

    - an act related to our unlawful stock repurchase or payment of a dividend
      under Section 174 of the Delaware General Corporation Law; or

    - transactions from which the director derived an improper personal benefit.

    These limitations of liability do not apply to liabilities arising under the
federal securities laws and do not affect the availability of equitable remedies
such as injunctive relief or rescission. Our certificate of incorporation also
authorizes us to indemnify its officers, directors and other agents to the
fullest extent permitted under Delaware law.

    As permitted by the Delaware General Corporation Law, our bylaws provide
that:

    - We are required to indemnify our directors and officers to the fullest
      extent permitted by the Delaware General Corporation Law, subject to
      limited exceptions;

    - We are required to advance expenses, as incurred, to our directors and
      officers in connection with a legal proceeding to the fullest extent
      permitted by the Delaware General Corporation Law, subject to limited
      exceptions; and

    - the rights provided in the bylaws are not exclusive.

    We have entered into indemnification agreements with each of our directors
and officers, and these indemnification agreements may be broader than the
specific indemnification provisions contained in the Delaware General
Corporation Law and may require us, among other things, to indemnify our
officers and directors against liabilities that may arise by reason of their
status or service as directors or officers, other than liabilities arising from
willful misconduct. These indemnification agreements also may require us to
advance any expenses incurred by the directors or officers as a result of any
proceeding against them as to which they could be indemnified and to obtain
directors' and officers' insurance if available on reasonable terms.

    At present, there is no pending litigation or proceeding involving any of
our directors, officers, employees or agents where indemnification by us is
sought. In addition, we are not aware of any threatened litigation or proceeding
which may result in a claim for indemnification.

    We have maintained directors' and officers' liability insurance since
September 1998, and we intend to continue to maintain this insurance in the
future.

                           RELATED PARTY TRANSACTIONS

RECAPITALIZATION

    On December 16, 1997, we effected a recapitalization through a series of
transactions. The recapitalization consisted of:

    - FINANCING TRANSACTION. We sold and issued 3,159,128 shares of our
      mandatorily redeemable convertible preferred stock at a price of $4.376
      per share. Entities affiliated with TA Associates, Inc. purchased
      3,147,702 of those shares for an aggregate purchase price of $13.8
      million. Michael C. Child and Kurt R. Jaggers, members of our Board of
      Directors, are Managing Directors of TA Associates, Inc. Upon the closing
      of this offering, each outstanding share of mandatorily redeemable
      convertible preferred stock will be converted into one share of our
      Series A redeemable preferred stock and 3.375 shares of our common stock,
      or a total of 10,662,057 shares of common stock. The Series A redeemable
      preferred stock is redeemable at our option or at the option of the
      holder. Upon the closing of this offering, we intend to use $12.4 million
      of the proceeds to redeem all of the outstanding shares of our Series A
      redeemable preferred stock.

    - TERM LOAN. We borrowed $15.0 million from Fleet National Bank. This term
      loan is payable in quarterly installments through December 2002 and bears
      interest, at our election, at the bank's prime rate plus 0.5% or the LIBOR
      rate plus 2.0%.

    - REPURCHASE. We used a portion of the proceeds from the financing
      transaction and the term loan to repurchase 15,892,250 shares, or
      approximately 92%, of our common stock owned by our then sole
      shareholders, Frank Deverse and his family partnership, Golden Legacy
      Limited Partnership, for a price of $1.517 per share, or $24.2 million. In
      addition to the proceeds from the financing transaction and term loan, we
      funded this repurchase through the issuance of a $2.5 million promissory
      note to Mr. Deverse. The note bears interest at a rate of 9.0% per annum,
      payable semiannually. The principal is due in equal semiannual payments
      beginning on the date we fully repay the $15.0 million dollar term loan,
      provided, however, that all unpaid principal and interest becomes due upon
      the earlier of December 16, 2003 or the closing of a qualified initial
      public offering. Golden Legacy delivered $1.3 million and 877,500 shares
      of our common stock into an escrow to provide a fund against which future
      claims for indemnification could be made by us or TA Associates for
      breaches of representations and warranties made by the sellers in
      connection with the repurchase.

    - OPTION BUYOUT. In connection with the repurchase of shares of our common
      stock, we also purchased outstanding options to purchase an aggregate of
      3,269,025 shares of our common stock from our employees at a net price of
      $1.19 per share, which consisted of $1.517 per share less their $0.32
      exercise price.

    - PUT OPTION. As a condition to the repurchase, we granted Golden Legacy
      Limited Partnership the right to require us to purchase an additional
      1,316,250 shares of our common stock at a price of $1.517 per share.

    - OTHER AGREEMENTS. We, affiliates of TA Associates and various other equity
      holders also entered into a stockholders agreement that, among other
      things, provides for restrictions on the transfer of shares, preemptive
      rights and registration rights. Additionally, the affiliates of TA
      Associates holding our mandatorily redeemable convertible preferred stock
      have the right to elect four of our directors, and to vote with other
      holders of our capital stock in the election of other directors.

SETTLEMENT OF CLAIMS

    In October 1998, TA Associates asserted various claims against Mr. Deverse
and Golden Legacy for alleged breaches of representations and warranties made in
connection with the repurchase of shares from them. We assigned to TA Associates
our rights to make claims based on these alleged breaches. Thereafter,
Mr. Deverse and Golden Legacy sought indemnification from us and from Ilhan
Refioglu, our President and Chief Executive Officer, and Judith A. Signorino,
our Vice President Finance and Chief Financial Officer, against the claims
asserted by TA Associates. In August 2000, the parties agreed in principle to a
resolution of the dispute under which the cash portion of the escrow fund and
accrued interest, totaling approximately $1.45 million, would be released to TA
Associates and the 877,500 shares of our common stock held in the escrow would
be released to Mr. Deverse and Golden Legacy. Formal documentation of the
settlement is pending.

LOANS TO EXECUTIVE OFFICERS

    In connection with the purchase of shares of our common stock by Ilhan
Refioglu, our President and Chief Executive Officer, we loaned Dr. Refioglu
$33,550 on December 16, 1997, $35,588 on August 18, 1998 and $54,450 on
January 3, 2000. These loans bear interest at a rate of 6.50% per annum, 5.12%
per annum and 6.07% per annum, respectively.

    In connection with the purchase of shares of our common stock by Gregory J.
Richmond, our Vice President, Engineering and Chief Technology Officer, we
loaned Mr. Richmond $48,000 on December 30, 1999 and $96,000 on January 3, 2000.
These loans bear interest at a rate of 6.07% per annum.

OTHER TRANSACTIONS

    We have entered into indemnification agreements with Mr. Child and
Mr. Jaggers. We also intend to enter into indemnification agreements with each
of our other directors and executive officers. See "Management--Indemnification
of Directors and Executive Officers and Limitation of Liability."

    We are a party to an employment agreement with Dr. Refioglu. See
"Management--Employment Contract."

     and generally includes voting or investment power with respect to
     securities. All shares of common stock subject to options exercisable
     within 60 days following July 31, 2000 are deemed to be outstanding and
     beneficially owned by the person holding those options for the purpose of

     ownership of that person. They are not, however, deemed to be outstanding
     and beneficially owned for the purpose of computing the percentage
     ownership of any other person. Accordingly, percent ownership is based on:

     July 31, 2000 plus any shares issuable pursuant to options held by the

                          DESCRIPTION OF CAPITAL STOCK

    Upon the closing of this offering, our authorized capital stock will consist
of 100,000,000 shares of common stock, $0.001 par value per share, and 5,000,000
shares of preferred stock, $0.001 par value per share.

    The following is a summary of the material terms of our common stock and
preferred stock. Please see our certificate of incorporation, filed as an
exhibit to the registration statement of which this prospectus is a part, for
more detailed information.

COMMON STOCK

    As of June 30, 2000, there were 15,235,479 shares of our common stock
outstanding held of record by 47 stockholders, assuming the conversion of our
convertible preferred stock into common stock. The holders of our common stock
are entitled to one vote for each share held of record on all matters submitted
to a vote of stockholders. Upon the closing of this offering, holders of a
majority of the shares of common stock entitled to vote in any election of
directors may elect all of the directors standing for election. Subject to
preferences applicable to any outstanding preferred stock, holders of common
stock are entitled to receive ratably any dividends declared by the board. In
the event of a liquidation, dissolution or winding up of the company, holders of
common stock are entitled to share ratably in the assets remaining after payment
of liabilities and the liquidation preferences of any outstanding preferred
stock. Holders of our common stock have no preemptive, conversion or redemption
rights. Each outstanding share of common stock is, and all shares of common
stock to be outstanding upon the closing of this offering will be, fully paid
and non-assessable.

PREFERRED STOCK

    Upon the closing of this offering, all outstanding shares of our mandatorily
redeemable convertible preferred stock will be converted into an aggregate of
10,662,057 shares of common stock and 3,159,128 shares of Series A redeemable
preferred stock, and all such shares of Series A redeemable preferred stock will
be redeemed. Thereafter, up to 5,000,000 shares of undesignated preferred stock
will be authorized for issuance. Our Board of Directors has the authority,
without further action by our stockholders, to issue preferred stock in one or
more series. In addition, the Board of Directors may fix the rights, preferences
and privileges of any preferred stock it determines to issue. Any or all of
these rights may be superior to the rights of the common stock. Preferred stock
could thus be issued quickly with terms calculated to delay or prevent a change
in control of the company or to make removal of management more difficult.
Additionally, the issuance of preferred stock may decrease the market price of
our common stock. At present, we have no plans to issue any shares of preferred
stock.

REGISTRATION RIGHTS

    Under the Stockholders Agreement dated as of December 16, 1997, holders of
an aggregate of       shares of our common stock, including the 10,662,057
shares of common stock into which outstanding shares of mandatorily redeemable
convertible preferred stock will be converted upon the closing of this offering,
have various registration rights.

    Beginning 90 days after the date of this prospectus, the purchasers of our
mandatorily redeemable convertible preferred stock have the right to require us,
on not more than two occasions, to file a registration statement under the
Securities Act to register the shares of common stock into which their
mandatorily redeemable convertible preferred stock is converted at our expense.
Demand for this registration must be made by holders of at least 50% of the
shares that are entitled to this registration. We may, under some circumstances,
defer this registration for up to 90 days, and the underwriters of the offering
under this registration have the right, subject to some limitations, to limit
the number of shares included.

                                       56
<PAGE>
    If we propose to register any of our securities under the Securities Act for
our own account or for the account of other security holders, the purchasers of
our mandatorily redeemable convertible preferred stock, as well as certain other
holders of our common stock, including Frank Deverse and Golden Legacy Limited
Partnership, are entitled to notice of that registration and have the right to
include some or all of their shares of common stock in that registration, at our
expense, subject to marketing and other limitations.

ANTITAKEOVER PROVISIONS

    DELAWARE LAW

    We will be subject to Section 203 of the Delaware General Corporation Law
regulating corporate takeovers, which prohibits a Delaware corporation from
engaging in any business combination with an "interested stockholder," unless:

    - prior to the date of the transaction, the board of directors of the
      corporation approved either the business combination or the transaction
      which resulted in the stockholder becoming an interested stockholder;

    - the interested stockholder owned at least 85% of the voting stock of the
      corporation outstanding at the time the transaction commenced, excluding
      for purposes of determining the number of shares outstanding (a) shares
      owned by persons who are directors and also officers, and (b) shares owned
      by employee stock plans in which employee participants do not have the
      right to determine confidentially whether shares held subject to the plan
      will be tendered in a tender or exchange offer; or

    - on or subsequent to the date of the transaction, the business combination
      is approved by the board and authorized at an annual or special meeting of
      stockholders, and not by written consent, by the affirmative vote of at
      least 66 2/3% of the outstanding voting stock which is not owned by the
      interested stockholder.

    Except as otherwise specified in Section 203, an "interested stockholder" is
defined to include (a) any person that is the owner of 15% or more of the
outstanding voting securities of the corporation, or is an affiliate or
associate of the corporation and was the owner of 15% or more of the outstanding
voting stock of the corporation at any time within three years immediately prior
to the date of determination and (b) the affiliates and associates of any such
person.

    CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS

    Provisions of our certificate of incorporation and bylaws, which will become
effective upon the closing of this offering, may have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party
from attempting to acquire, control of the company. These provisions could cause
the price of our common stock to decrease. Some of these provisions allow us to
issue preferred stock without any vote or further action by the stockholders,
eliminate the right of stockholders to act by written consent without a meeting
and eliminate cumulative voting in the election of directors. These provisions
may make it more difficult for stockholders to take specific corporate actions
and could have the effect of delaying or preventing a change in control of the
company.

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for the common stock is             .

LISTING

    We have applied to have our common stock approved for listing on the Nasdaq
National Market under the trading symbol "IIMI."

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE

    Prior to this offering, there has not been a public market for out common
stock. Future sales of substantial amounts of our common stock in the public
market, or the possibility of these sales, could adversely affect the trading
price of our common stock.

    Upon completion of this offering, we will have outstanding
shares of common stock, assuming no exercise of the underwriters' over-allotment
option and no exercise of outstanding options to purchase common stock after
June 30, 2000. Of these shares, the             shares sold in this offering
will be freely tradable without restriction or further registration under the
Securities Act, except for any shares purchased by our "affiliates," as defined
in Rule 144 under the Securities Act, which would be subject to the limitations
and restrictions described below.

    The remaining             shares of common stock outstanding upon completion
of this offering will be "restricted securities" as defined in Rule 144. These
securities may be sold in the public market only if registered or if they
qualify for an exemption from registration under Rules 144 or 701 under the
Securities Act, which are summarized below. Sales of these restricted securities
in the public market, or the availability of these shares for sale, could
adversely affect the trading price of our common stock.

    Holders of approximately             of these restricted securities,
including all of our officers and directors and the entities affiliated with
them, have entered into lock-up agreements providing that, subject to limited
exceptions, they will not sell, directly or indirectly, any common stock without
the prior consent of Wit SoundView Corporation for a period of 180 days from the
date of this prospectus.

    The number of restricted securities that will be available for sale in the
public market, subject in some cases to the volume limitations and other
restrictions of Rule 144, will be as follows:

    - approximately             shares will be eligible for immediate sale as of
      the date of this prospectus;

    - approximately             additional shares will be eligible for sale
      beginning 90 days after the date of this prospectus under Rules 144 and
      701; and

    - approximately             additional shares will be eligible for sale
      beginning 180 days after the date of this prospectus upon expiration of
      the lock-up agreements described above.

    Approximately             remaining restricted securities will not be
eligible for sale pursuant to Rule 144 until the expiration of their applicable
one-year holding periods, which will expire between             2000 and
            2000.

    In general, under Rule 144, beginning 90 days after the date of this
prospectus, a person (or persons whose shares are aggregated) who has
beneficially owned restricted securities for at least one year would be entitled
to sell within any three-month period a number of shares not to exceed the
greater of (1) one percent of the then outstanding shares of common stock or
(2) the average weekly trading volume of our common stock during the four
calendar weeks preceding the filing of a Form 144 with respect to the sale.
Sales under Rule 144 are also subject to manner of sale and notice requirements,
as well as to the availability of current public information about us. Under
Rule 144(k), a person who is not deemed to have been an affiliate at any time
during the 90 days preceding a sale and who has beneficially owned the shares
proposed to be sold for at least two years is entitled to sell the shares
without complying with the manner of sale, public information, volume limitation
or notice provisions of Rule 144. Shares issued upon exercise of options granted
by us prior to the date of this prospectus will be available for sale in the
public market under Rule 701 of the Securities Act. Rule 701 permits resales of
these shares in reliance upon Rule 144 but without compliance with various
restrictions, including the holding period requirement, imposed under Rule 144.

</TABLE>

    The underwriting agreement provides that the underwriters are obligated to
purchase all of the shares in the offering if any are purchased, other than
those shares covered by the over-allotment option described below. The
underwriting agreement also provides that if an underwriter defaults, the
purchase commitments of non-defaulting underwriters may be increased or the
offering may be terminated. The obligations of the underwriters under the
underwriting agreement may be terminated [at their discretion on the basis of
their assessment of the state of the]financial markets and also upon the
occurrence of events stated in the underwriting agreement.

    We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to       additional shares from us at the public offering price
less the underwriting commissions. The option may be exercised only to cover any
over-allotments of shares.

    The underwriters propose to offer our shares initially at the public
offering price on the cover page of this prospectus and to selling group members
at that price less a concession of $      per share. The underwriters and
selling group members may allow a discount of $      per share on sales to other
broker/dealers. After the public offering, the public offering price and
concession and discount to broker/dealers may be changed by the representatives.

    The following table summarizes the compensation and estimated expenses we
will pay.

    The underwriters have reserved for sale, at the public offering price, up to
      shares for our employees, directors and other persons associated with us
who have expressed an interest in purchasing common stock in the offering. The
number of shares available for sale to the general public in the offering will
be reduced to the extent that these persons purchase reserved shares. Any
purchaser of

                                       60
<PAGE>
reserved shares that is associated with a member of the National Association of
Securities Dealers, Inc. will agree not to resell the shares within 90 days
after the date of this prospectus. Any reserved shares which are not purchased
will be offered by the underwriters to the general public on the same terms as
the other shares.

    The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the shares being offered.

    We have agreed, subject to some exceptions, that we will not offer, sell,
contract to sell, pledge or otherwise dispose of, directly or indirectly, or
file with the Securities and Exchange Commission, a registration statement under
the U.S. Securities Act of 1933 relating to any of our shares or securities
convertible into or exchangeable or exercisable for any of our shares, or
publicly disclose the intention to make any such offer, pledge, disposition or
filing, without the prior written consent of Wit SoundView Corporation for a
period of 180 days after the date of this prospectus.

    Our officers, directors and other stockholders that own collectively
      shares have agreed that they will not offer, sell, contract to sell,
pledge or otherwise dispose of, directly or indirectly, any of our shares or
securities convertible into or exchangeable or exercisable for any of our
shares, enter into a transaction which would have the same effect, or enter into
any swap, hedge or other arrangement that transfers, in whole or in part, any of
the economic consequences of ownership of our shares, whether settled by
delivery of our shares or such other securities, in cash or otherwise, or
publicly disclose the intention to make any such offer, sale, pledge or
disposition, or to enter into any such transaction, swap, hedge or other
arrangement, without, in each case, the prior written consent of Wit SoundView
Corporation for a period of 180 days after the date of this prospectus.

    We have agreed to indemnify the underwriters against liabilities under the
Securities Act of 1933 or contribute to payments which the underwriters may be
required to make in respect of those liabilities.

    We have applied to list the shares on the Nasdaq National Market.

    There has been no active public market for our shares. The offering price is
to be determined through negotiations between us and the representatives of the
underwriters. The principal factors considered in determining the offering
price, in addition to prevailing market conditions, include:

    - the recent market prices of, and the demand for, publicly traded shares of
      generally comparable companies;

    - our current financial condition;

    - the history of, and the prospects for, our company and the industry in
      which we compete;

    - the ability of our management;

    - our past and present operations;

    - the prospects for, and anticipated timing of, our future revenue;

    - the present state of our development;

    - the percentage interest being sold by us as compared to our valuation; and

    - the above factors in relation to market values and various valuation
      measures of other companies engaged in activities similar to ours.

    In connection with this offering, the underwriters may engage in stabilizing
transactions, over-allotment transactions, syndicate covering transactions and
penalty bids, in accordance with Regulation M under the Securities Exchange Act
of 1934.

                                       61
<PAGE>
    - Over-allotment involves sales by the underwriters in excess of the number
      of shares the underwriters are obligated to purchase, which creates a
      syndicate short position. The short position may be either a covered short
      position or a naked short position. In a covered short position, the
      number of shares over-allotted by the underwriters is not greater than the
      number of shares which they may purchase in the over-allotment option. In
      a naked short position, the number of shares involved is greater than the
      number of shares in the over-allotment option. The underwriters may close
      out any short position by either exercising their over-allotment option
      and/or purchasing shares in the open market.

    - Stabilizing transactions permit bids to purchase the underlying security
      so long as the stabilizing bids do not exceed a specified maximum.

    - Syndicate covering transactions involve purchases of the shares in the
      open market after the distribution has been completed in order to cover
      syndicate short positions. The short position may be either a covered
      short position or a naked short position. In a covered short position, the
      number of shares over-allotted by the underwriters is not greater than the
      number of shares which they may purchase in the over-allotment option. In
      a naked short position, the number of shares involved is greater than the
      number of shares in the over-allotment option. The underwriters may close
      out any short position by either exercising their over-allotment option
      and/or purchasing shares in the open market.

    - Penalty bids permit the representatives to reclaim a selling concession
      from a syndicate member when the shares originally sold by the syndicate
      member are purchased in a stabilizing or syndicate covering transaction to
      cover syndicate short positions.

To the Board of Directors and Shareholders of
  International Microcircuits, Inc.

    The reincorporation in Delaware and stock split described in Note 12 to the
financial statements have not been consummated at September 5, 2000. When the
reincorporation in Delaware and stock split have been consummated, we will be in
a position to furnish the following report:

        "In our opinion, the accompanying consolidated balance sheets and the
    related consolidated statements of operations, of changes in stockholders'
    equity (deficit) and of cash flows present fairly, in all material respects,
    the financial position of International Microcircuits, Inc. and its
    subsidiary at March 31, 1999 and 2000, and the results of their operations
    and their cash flows for each of the three years in the period then ended,
    in conformity with accounting principles generally accepted in the United
    States. These financial statements are the responsibility of the Company's
    management; our responsibility is to express an opinion on these financial
    statements based on our audits. We conducted our audits of these statements
    in accordance with auditing standards generally accepted in the United
    States, which require that we plan and perform the audit to obtain
    reasonable assurance about whether the financial statements are free of
    material misstatement. An audit includes examining, on a test basis,
    evidence supporting the amounts and disclosures in the financial statements,
    assessing the accounting principles used and significant estimates made by
    management, and evaluating the overall financial statement presentation. We
    believe that our audits provide a reasonable basis for the opinion expressed
    above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1--THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES:

THE COMPANY

    International Microcircuits, Inc. (the "Company") was incorporated in
California in 1972 and is a leading supplier of timing and EMI reduction
integrated circuits for a broad range of applications.

PRINCIPLES OF CONSOLIDATION

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary, Inter-Mic, a Foreign Sales Corporation. All
significant intercompany balances and transactions are eliminated in
consolidation.

UNAUDITED INTERIM FINANCIAL INFORMATION

    The accompanying interim consolidated balance sheet as of June 30, 2000,
consolidated statements of operations and cash flows for the three months ended
June 30, 1999 and 2000 and the consolidated statement of changes in
stockholders' equity (deficit) for the three months ended June 30, 2000,
together with related notes are unaudited. In the opinion of management such
unaudited information includes all adjustments, consisting of only normal
recurring adjustments, which the Company considers necessary to present fairly,
in all material respects, the Company's consolidated financial position as of
June 30, 2000, the results of operations and cash flows for the three months
ended June 30, 1999 and 2000 and changes in stockholders' equity (deficit) for
the three months ended June 30, 2000. Results of operations for the three months
ended June 30, 2000 are not necessarily indicative of the results for the entire
fiscal year of for any other future period.

RECAPITALIZATION

    During the year ended March 31, 1998, the Company entered into a series of
agreements providing for the recapitalization of the Company (the
"Recapitalization"). The Recapitalization was comprised of a number of
interrelated transactions including (i) the redemption of approximately 92% of
the shares of common stock owned by the then sole stockholder (the
"Redemption"); (ii) the sale of 3,159,128 shares of the Company's Mandatorily
Redeemable Convertible Preferred Stock for $13.8 million to investors to
partially finance the Redemption; (iii) the borrowing from a financial
institution of $15.0 million to provide additional financing for the Redemption
and the ongoing operations of the Company; and (iv) the repurchase of a portion
of the outstanding options to purchase shares of the Company's common stock.

    Until November 19, 1997, the Company's common stock was owned by a sole
stockholder, at which time the Company began a series of transactions which
redeemed 15,896,250 shares of the sole stockholder's total holdings of
17,213,000 shares of common stock for $1.51 per share, or $24.3 million
including repurchase costs. The Redemption was paid by $21.8 million of cash and
issuance of a $2.5 million promissory note. Pursuant to the Recapitalization and
Redemption, the stockholder also has the right to require the Company to
repurchase his remaining 1,316,250 shares of common stock at any time after the
second anniversary of the closing of the Redemption but before the third
anniversary of the closing of the Redemption, at a per share purchase price of
$1.51.

    Based upon the voting rights of the holders of Mandatorily Redeemable
Convertible Preferred Stock, such stockholders control the Company and have the
right to elect the Company's Board of Directors and to influence other aspects
of the Company's business. See Note 6. The issuance of the

                       INTERNATIONAL MICROCIRCUITS, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1--THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
Mandatorily Redeemable Convertible Preferred Stock resulted in a beneficial
conversion feature in the amount of $192,000, which was recorded as a deemed
dividend on preferred stock over the two year period from issuance to when the
security became convertible.

    The 1995 Stock Option Plan provides that all outstanding options to purchase
the Company's common stock vest immediately upon close of a Change in Control
event, as defined. The sale of the Mandatorily Redeemable Convertible Preferred
Stock resulted in such a Change in Control event and, therefore, all of the
options then outstanding became fully vested. The Company, however, purchased
for cash from participating employees, at a net price of $1.19 per share,
options to purchase 3,269,025 shares of common stock, representing the $1.51 per
share paid in connection with the Redemption, less the $0.32 exercise price of
the options purchased from the employees. The aggregate cash payment of
$3.9 million was recorded as employee compensation expense in the accompanying
statement of operations for the year ended March 31, 1998. The remaining
outstanding options at the date of consummation of the Recapitalization
(i) were exercised for cash, (ii) were exercised by issuance of a promissory
note or (iii) remained outstanding.

STOCK SPLIT

    In February 1998, the Company effected a three-for-two stock split. In
February 2000, the Company effected another three for two stock split. The
number of shares and prices of common stock and options presented in these
financial statements have been retroactively restated to give effect to the
stock splits.

REVENUE RECOGNITION

    Revenue from product sales to original equipment manufacturers and from
sales to distributors who have no, or limited, product return rights and no
price protection rights, is recognized upon shipment, net of allowances for
estimated returns. When distributors have product return or price protection
rights, the Company defers revenue recognition until the time the distributor
sells the product to the end customer. For products shipped to distributors, no
revenue or cost of sales is recorded. However, the Company records a receivable
for the selling price, relieves inventory at cost of goods shipped and defers
the margin in accrued liabilities.

CONCENTRATION OF CREDIT RISK, FOREIGN OPERATIONS AND SIGNIFICANT CUSTOMERS

    Financial instruments which potentially subject the Company to concentration
of credit risk consist principally of trade accounts receivable. The majority of
the Company's receivables are derived from sales to customers in the computer
and telecommunication markets in the United States, Asia and Europe.
Concentrations of credit risk with respect to trade receivables for
international sales are limited as the sales are primarily made under letter of
credit arrangements or the sales amounts are prepaid by the customer. The
Company maintains an allowance for uncollectible accounts receivable based upon
expected collectibility. The Company's write-offs of accounts receivable were
not significant for each of the three years ended March 31, 2000.

    The Company's sales are denominated in U.S. dollars and the risk of foreign
exchange fluctuations has been minimal.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1--THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    The Company is dependent on independent foundries and a limited number of
assembly subcontractors with whom it has no long term contracts. The inability
or unwillingness of these suppliers to meet the Company's requirements would
delay our product shipments and harm our business.

INVENTORY

    Inventory is stated at the lower of cost or market, cost being determined
using the first-in, first-out method.

PROPERTY AND EQUIPMENT

    Property and equipment and leasehold improvements are recorded at cost less
accumulated depreciation and amortization. Depreciation and amortization are
computed using the straight-line method over the estimated useful lives of the
assets which are generally three to five years. Leasehold improvements and
equipment under capital leases are amortized over the shorter of the lease term
or their estimated useful lives.

LONG-LIVED ASSETS

    The Company reviews for the impairment of long-lived assets whenever events
or changes in circumstances indicate that the carrying amount of an asset may
not be recoverable. An impairment loss would be recognized when estimated future
cash flows expected to result from the use of the asset and its eventual
disposition is less than its carrying amount. No such impairment losses have
been identified by the Company.

USE OF ESTIMATES

    The preparation of these consolidated 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 at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could vary
from those estimates.

STOCK COMPENSATION

    The Company accounts for stock-based employee compensation arrangements
using the intrinsic value method as prescribed in Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB No. 25").
Accordingly, compensation cost for stock options is measured as the excess, if
any, of the fair value of the Company's stock at the date of grant over the
stock option exercise price. Expense associated with stock-based compensation is
amortized on an accelerated basis over the vesting period of the individual
award consistent with the method described in Financial Accounting Standards
Board Interpretation No. 28 ("FIN 28"). The Company accounts for stock issued to
nonemployees in accordance with the provisions of Statement of Financial
Accounting standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS
No. 123") and Emerging Issues Task Force Consensus No. 96-18, stock option
awards issued to nonemployees are accounted for at their fair value, determined
using the Black-Scholes option pricing method. The fair value of each
nonemployee

stock option or award is remeasured at each period end until a commitment date
is reached, which is generally the vesting date.

COMPREHENSIVE INCOME

    In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards
for reporting and display of comprehensive income and its components and is
effective for periods beginning after December 15, 1997. The Company had no
items of other comprehensive income during any of the periods presented.

NET INCOME (LOSS) PER SHARE

    The Company reports both basic net income (loss) per share, which is based
on the weighted average number of common shares outstanding excluding
contingently issuable or returnable shares, and diluted net income (loss) per
share which is based on the weighted average number of common shares outstanding
and dilutive potential common shares outstanding. Diluted net income per share
includes the conversion of the Mandatorily Redeemable Preferred Stock into
common stock and Series A Redeemable Preferred Stock as if the conversion
occurred at the beginning of the period. Dividends related to Series A
Redeemable Preferred Stock reduce net income available to common stockholders.
All potential dilutive securities are excluded from the calculation in the year
ended March 31, 1998 as their inclusion would be anti-dilutive.

PRO FORMA NET INCOME PER SHARE (UNAUDITED)

    Pro forma basic net income per share for the year ended March 31, 2000 and
three months ended June 30, 2000 is computed using the weighted average number
of common shares outstanding, including the conversion of all the outstanding
shares of Mandatorily Redeemable Convertible Preferred Stock into 10,662,057
shares of common stock and 3,159,128 shares of Series A Redeemable Preferred
Stock effective upon the closing of the Company's initial public offering, as if
such conversion occurred on April 1, 1999 and April 1, 2000, respectively. Pro
forma diluted net income per share is computed using the pro forma weighted
average number of common and potential common shares outstanding. Pro forma
potential common shares consist of common stock subject to repurchase and stock
options and warrants using the treasury stock method.

PRO FORMA MANDATORILY REDEEMABLE PREFERRED SECURITIES AND STOCKHOLDERS' EQUITY

converted into 10,662,057 shares of common stock and 3,159,128 shares of
Series A redeemable preferred stock. The pro forma effects of these transactions
are unaudited and have been reflected in the accompanying pro forma statement of
stockholders' equity as if such conversion had occurred at June 30, 2000.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the FASB issued Statement on Financial Accounting Standards
No. 133 ("SFAS No. 133"), "Accounting for Derivative Instruments and Hedging
Activities." SFAS No. 133 establishes a new model for accounting for derivatives
and hedging activities and supercedes and amends a number of existing accounting
standards. SFAS No. 133 requires that all derivatives be recognized in the
balance sheet at fair market value, and the corresponding derivative gains or
losses be either reported in the statement of operations or as a deferred item
depending on the type of hedge relationship that exists with respect to such
derivative. The Company currently does not hold any derivative instruments that
will be affected by the adoption of SFAS No. 133.

    In December 1999, the Securities and Exchange Commission (SEC) issued Staff
Accounting Bulletin No. 101 (SAB 101), "Revenue Recognition," which provides
guidance on the recognition, presentation and disclosure of revenue in financial
statements filed with the SEC. SAB 101 outlines the basic criteria that must be
met in order to recognize revenue and provides guidance for disclosures related
to revenue recognition policies. In June 2000, the SEC issued SAB 101B,
"Amendment: Revenue Recognition in Financial Statements" which extends the
effective date of SAB 101 to the fourth fiscal quarter of fiscal years
commencing after December 15, 1999. The SEC is preparing to issue interpretative
guidance relating to SAB 101, and the FASB continues to address revenue and
other related accounting issues. The management of the Company believes it is in
compliance with all of the rules and related guidance as they currently exist
related to SAB 101. However, any changes to generally accepted accounting
principles in these areas could impact the Company's accounting for its
operations.

    In March 2000, the Financial Accounting Standards Board issued
Interpretation No. 44, "Accounting for Certain Transactions Involving Stock
Compensation--an interpretation of APB Opinion No. 25" ("FIN 44"). This
Interpretation clarifies the definition of employee for the

plan qualifies as a noncompensatory plan, the accounting consequences of various
modifications to the terms of a previously fixed stock option or award, and the
accounting for an exchange of stock compensation awards in a business

conclusions in this Interpretation cover specific events that occur after either
December 15, 1998, or January 12, 2000. Management believes that FIN 44 will not
have a material effect on the financial position or results of operations of the
Company.

    Pursuant to the Recapitalization, the Company borrowed $15 million under a
term loan arrangement from a bank. The term loan bears interest at either the
bank's prime rate (9% at March 31, 2000) plus 0.5% or the LIBOR rate (7% at
March 31, 2000) plus 2.0%, at the election of the Company. On September 11,
1998, the term loan agreement was amended to reduce the quarterly principal
payments and to waive compliance with certain covenants. The term loan is
payable in quarterly installments of principal and interest through
December 2002. The Agreement requires that the Company maintain certain
financial covenants with which it was in compliance at March 31, 2000. Debt
issuance costs of $325,000 are being amortized over the term of the term loan.
During the year ended March 31, 2000, the Company made principal payments on the
term loan aggregating $1,800,000, of which $900,000 were made in advance of the
scheduled due date. During the three month period ended June 30, 2000, the
Company made principal payments on the term loan aggregating $750,000, all of
which were made in advance of the scheduled due date (unaudited).

PROMISSORY NOTE

    In December 1997, the Company borrowed $2.5 million under a promissory note
(the "Note") issued to the Company's former sole stockholder pursuant to the
Redemption. The Note bears interest at 9% per annum. Interest on the unpaid
principal balance is payable semi-annually. The principal balance will be
payable in equal semiannual installments beginning on the date the Company has
fully repaid the $15 million term loan, provided, however, that all principal
and accrued interest will be due

MANDATORILY REDEEMABLE COMMON STOCK

    Pursuant to the Recapitalization and the Redemption, the Company redeemed
15,896,250 shares of common stock held by its sole stockholder. In addition, the
sole stockholder obtained the right to redeem his remaining 1,316,250 shares of
common stock during the period from the second anniversary of the closing of the
Redemption to the third anniversary of the closing of the Redemption at a per
share price of $1.51. As a result of this redemption right, the Company has
reclassified these shares from common stock to mandatorily redeemable
securities. The Company has accreted to the mandatory redemption amount of
$1,997,000 over the two year period from the closing date of the Redemption to
the date the shares became redeemable. Such accretion aggregated $26,000,
$404,000 and $1,524,000 for the years ended March 31, 1998, 1999 and 2000,
respectively. At March 31, 2000, the shares were redeemable by the holder.

MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK AND SERIES A REDEEMABLE
  PREFERRED STOCK

    Pursuant to the Recapitalization, the Company issued 3,159,128 shares of
Mandatorily Redeemable Convertible Preferred Stock at a purchase price of $4.376
per share.

    The Mandatorily Redeemable Convertible Preferred Stock and Series A
Redeemable Preferred Stock have certain rights with respect to voting,
dividends, liquidation, redemption and conversion as follows:

    VOTING--The holders of Mandatorily Redeemable Convertible Preferred Stock
are entitled to elect four Directors of the Company and are entitled to vote for
all other Directors of the Company with holders of other shares of capital stock
on an equal basis. The holders of Mandatorily Redeemable Convertible Preferred
Stock are entitled to vote together with holders of common stock upon all
matters submitted to a vote of shareholders on an equal basis, excluding those
matters required to be submitted to a class or series vote. Holders of Series A
Redeemable Preferred Stock are not entitled to vote on any matters except to the
extent otherwise required under the Corporation Law. The holders of Series A
Redeemable Preferred Stock are entitled to elect one Director.

NOTE 6--MANDATORILY REDEEMABLE SECURITIES: (CONTINUED)
also declared on all outstanding shares of common stock. Holders of Series A
Redeemable Preferred Stock are entitled to receive cumulative dividends at a per
share rate of 6% of $3.9384 per annum, whether or not they have been declared
and whether or not there are profits, surplus, or other funds of the Company
legally available for the payment of dividends, and in preference to any
declaration or payment of any dividend on the common stock or other capital
stock of the Company ranking junior to Series A Redeemable Preferred Stock. The
issuance of the Mandatorily Redeemable Convertible Preferred Stock resulted in a
beneficial conversion feature in the amount of $192,000, which was reflected as
a deemed dividend on preferred stock over the two year period from issuance to
when the security became convertible. Deemed dividends on preferred stock
totaled $24,000, $96,000 and $72,000 for the years ended March 31, 1998, 1999
and 2000, respectively.

    LIQUIDATION--Upon any liquidation, dissolution or winding up of the Company,
the holders of Mandatorily Redeemable Convertible Preferred Stock are entitled
to receive, prior to any distribution to the holders of common stock or of any
other stock ranking on liquidation junior to Mandatorily Redeemable Convertible
Preferred Stock, an amount equal to $4.376 per share, plus any accumulated but
unpaid dividends and any interests accrued to which such holder is then
entitled. However, if the holders would receive more in the event their shares
were converted into Series A Redeemable Preferred Stock and common stock (see
below for conversion rights), then each holder would receive an amount equal to
such holder's Series A Redeemable Preferred Stock liquidation preference amount
(as defined below), plus any dividends accumulated but unpaid, in addition to an
amount equal to such holder's common stock liquidation preference amount. The
holders of Series A Redeemable Preferred Stock are entitled to receive, prior
and in preference to any distribution to the holders of common stock or of any
other stock ranking on liquidation junior to Series A Redeemable Preferred
Stock, an amount equal to $3.9384 per share plus any accumulated but unpaid
dividends and any interests accrued to which such holder is then entitled.

    REDEMPTION--At any time after December 5, 2003, any holder of Mandatorily
Redeemable Convertible Preferred Stock may require the Company to redeem up to
50% of the outstanding shares held by such holder at $4.376 per share. At any
time after December 5, 2004, any holder of Mandatorily Redeemable Convertible
Preferred Stock may require the Company to redeem up to all the outstanding
shares held by such holder. The Company shall redeem all outstanding shares of
Series A Redeemable Preferred Stock upon the election of at least 66 2/3% of the
holders upon the closing of a qualified initial public offering ("IPO").
Pursuant to a request of the principal underwriter or the Company at the closing
of an IPO, and upon the election of at least 66 2/3% of the holders of Series A
Redeemable Preferred Stock, the holders can agree to waive their redemption
election right. In the event that this may occur, all outstanding shares shall
be exchanged for notes ("Series A Notes") in the aggregate principal amount
equal to the aggregate Series A Redeemable Preferred Stock redemption price
equal to $3.9384 per share. The Series A Notes shall mature on the second
anniversary of the IPO effective date and bear interest at a rate of 10% per
annum. The Company may also elect to redeem all shares of Series A Redeemable
Preferred Stock at any time upon the closing of an IPO. At any time after the
later of the first anniversary of the date of conversion of the Mandatorily
Redeemable Convertible Preferred Stock and December 5, 2003, the Company may
elect, or any Series A Redeemable Preferred Stock holder may require the
Company, to redeem up to 50% of the outstanding shares held by the holder. At
any time after the later of the second anniversary of the date of the conversion
of the Mandatorily Redeemable Convertible Preferred Stock and December 5, 2004,

the Company may elect, or any Series A Redeemable Preferred Stock holder may

holder.

    CONVERSION--The holders of Mandatorily Redeemable Convertible Preferred
Stock have conversion rights, subject to the election of at least 66 2/3% of the
holders. Each share of Mandatorily Redeemable Convertible Preferred Stock is
convertible into one share of Series A Redeemable Preferred Stock and the number
of shares of common stock which results from dividing the per share Conversion
Value by the Conversion Price per share (at issuance, the conversion ratio into
common stock was one-for-one, subject to adjustments for future stock splits and
dividends). At March 31, 2000, the per share Conversion Value was $4.376 and the
Conversion Price per share was $1.30. The Mandatorily Redeemable Convertible
Preferred Stock shall be automatically converted into shares of common stock and
Series A Redeemable Preferred Stock as of the closing of the Company's first
underwritten offering to the public provided that (i) such offering generates
net proceeds of not less than $20 million at a price of $8.75 per share of
common stock, (ii) such stock is listed on either the New York Stock Exchange or
the NASDAQ National Market System, and (iii) if a redemption of Series A
Redeemable Preferred Stock is made, either (A) all outstanding shares of
Series A Redeemable Preferred Stock are redeemed, (B) cash in an amount
sufficient to redeem all outstanding shares of Series A Redeemable Preferred
Stock is segregated and irrevocably held by the Company for payment to holders
of Series A Redeemable Preferred Stock or (C) all outstanding shares of
Series A Redeemable Preferred Stock are exchanged for Series A Notes. A
sufficient number of shares of common stock and Series A Redeemable Preferred
Stock are reserved to satisfy the rights of conversion of the holders of the
Mandatorily Redeemable Convertible Preferred Stock.

NOTE 7--STOCK OPTION PLANS:

    The Company's 1995 Stock Option Plan (the "1995 Plan") was adopted by the
Company's Board of Directors in November 1995. The 1995 Plan provided for grants
of incentive stock options to employees, nonemployee directors and consultants
at prices determined by the Board of Directors, subject to certain conditions as
defined. Generally, these conditions limited prices for the grants ranging from
85% to 110% of the fair market value of the stock, as determined by the Board of
Directors, at the date of grant based on the type of the award and the number of
shares of common stock held by the grantee at the date of the award. Options
generally vest at a rate of not less than 25% per year over four years following
the date of grant subject to the optionee's continuous service or vest
immediately upon a Change in Control event.

    In November 1997, the Company adopted the 1997 Equity Incentive Plan (the
"1997 Plan") which provides for granting of incentive and nonstatutory stock
options, stock bonuses, restricted stock purchase rights and stock appreciation
rights ("SARs"). Incentive stock options and stock appreciation rights may be
granted only to employees, and stock awards other than incentive stock options
and stock appreciation rights may be granted only to employees, directors or
consultants. The 1997 Plan permits the optionee to surrender an exercisable SAR
for an amount equal to the excess of the market price of the common stock over
the SAR price when the right is exercised. There were no outstanding SARs at
March 31, 2000.

    Options granted under the 1997 Plan are generally for periods not to exceed
ten years and are granted at prices not less than 100% and 85%, for incentive
and nonstatutory stock options, respectively, of the fair market value of the
stock, as determined by the Board of Directors, on the date

of grant. Incentive stock options or awards to purchase restricted stock granted
to stockholders who own greater than 10% of the outstanding stock are for
periods not to exceed five years, and must be issued at prices not less than
110% of the fair market value of the stock on the date of grant, or in the case
of restricted stock purchase award, the purchase price is at least 100% of the
fair market value of the stock on the date of grant. Subject to certain
provisions of the 1997 Plan relating to changes in stock ownership, no person
shall be eligible to be granted options and stock appreciation rights covering
more than 750,000 shares of the Company's common stock in any twelve month
period. Options granted under the 1997 Plan will generally provide for vesting
of at least 20% per year of the total number of shares subject to the option. A
total of 5,540,437 shares of common stock have been reserved for issuance under
the 1997 Plan at March 31, 2000.

    Restricted stock awards issued under the 1997 Plan provide that the purchase
price shall in no event be less than 85% of the stock's fair market value on the
date such award is made. There was no restricted stock issued under the 1997
Plan as of March 31, 2000.

    Activity under the 1995 and 1997 Plans is summarized as follows:

FAIR VALUE DISCLOSURES

    For purposes of the following pro forma disclosures, the fair value of each
option grant is estimated on the date of grant using the minimum value method
with the following assumptions used for grants in the years ended March 31,
1998, 1999 and 2000: dividend yield of 0.0%; average risk free interest rates of
5.04% through 6.56% and weighted average option life of five years. The weighted
average fair value of options granted during the years ended March 31, 1998,
1999 and 2000 with exercise prices equal to the market price at the date of
grant is $0.47, $0.35 and $0.86 per share, respectively. Had compensation cost
for the Company's stock-based compensation plan been determined based on the
fair value at the grant dates for the awards under a method prescribed by SFAS
No. 123, the Company's net income (loss) would have been the pro forma amounts
indicated below:

REPURCHASED OPTIONS

    Pursuant to the Recapitalization, the Company offered to purchase previously
granted options held by employees for 3,793,838 shares of common stock at a net
price of $1.19 per share. Employees accepted the Company's offer with respect to
options for an aggregate of 3,269,025 shares, and the Company purchased these
options from employees for cash totaling $3,894,000. The Company recorded a
charge of $4,519,000 in December 1997 relating to the purchase and offer to
purchase such options.

NOTE 7--STOCK OPTION PLANS: (CONTINUED)
The remaining outstanding options not purchased by the Company were exercised
for cash or stockholder notes at $0.48 per share, or remained outstanding.

STOCK COMPENSATION

    During the year ended March 31, 1998, the Company determined that $1,197,000
of stock compensation existed relating to certain options granted during the
year. The Company began recognizing the compensation ratably over the vesting
period and expensed a total of $284,000 until the Recapitalization, at which
time all options outstanding became immediately vested. The unrecognized stock
compensation for these options of $913,000 was expensed as part of the charge
recorded in connection with the Company's offer and purchase of options
described above.

    In connection with certain employee stock option grants, the Company
recognized deferred stock-based compensation, which is being amortized over the
vesting periods of the related options, generally four years, using an
accelerated basis. Future compensation charges are subject to reduction for any
employee who terminates employment prior to such employee's option vesting date.
During the years ended March 31, 1999 and 2000 and the three months ended
June 30, 2000, the Company granted options and recorded deferred stock-based
compensation of $71,000, $3,634,000 and $2,188,000 (unaudited), respectively,
net of reversals associated with unvested shares of terminated employees.
Unamortized deferred stock-based compensation at March 31, 1999, March 31, 2000
and June 30, 2000 was $64,000, $2,724,000 and $4,223,000 (unaudited),
respectively.

SHAREHOLDER NOTES

    At March 31, 1999 and 2000, stockholder notes used to exercise options to
purchase common stock were outstanding totaling $168,000 and $367,000,
respectively. Interest on the stockholder notes ranges from 5.12% to 6.50% per
annum, compounded annually, and payable on each December 31 during the term of
the notes. The principal portion of the stockholder notes matures in 6 years,
but can be paid in full before maturity at the option of the holder. The Company
recorded stock compensation of $255,000 and $39,000 related to outstanding
stockholder notes during fiscal 1999 and 2000, respectively, representing the
difference between the original exercise price of the stock options and the fair
market value of the Company's common stock at each respective year end. In
June 1999, the shareholder notes were amended so that no further stock
compensation expense will be recorded.

OPTIONS TO CONSULTANTS

    In May 2000, the Company entered into an agreement to receive design
services in exchange for cash and an option to purchase 60,000 shares of common
stock at $0.95 per share. The option will become exercisable in increments as
the services are performed and will be accounted for as a variable award. At
June 30, 2000, approximately 6,000 shares were earned and had become exercisable
and the Company expensed the related fair value of approximately $59,000. The
Company believes that the fair value of the stock options are more reliably
measurable than the fair value of the services received.

for high performance electronic systems"

    Script: (Ilhan Refioglu) (see "Business--Industry Background--Demand for
High Performance Electronic Systems") Electronic systems play an increasingly
important role in our lives, as evidenced by the growth in personal computing,
communications and consumer electronics markets. The growth of these markets has
been driven by the demand for, and availability of, electronic systems
characterized by ever-improving performance, flexibility, reliability and
functionality, as well as decreasing size, cost and power consumption. In
addition, the dramatic growth of the Internet has resulted in consumer demand
for greater bandwidth and higher speed. These demands have resulted in both the
development of new, and the enhancement of existing products such as digital
cameras, DVD

                                      A-1

players, game consoles, internet appliances, network routers and switches,
notebook computers and set-top boxes.

    Advances in integrated circuits and improvements in semiconductor technology
have contributed significantly to the increased performance of, and demand for,
these electronic systems. These advances have also enabled the continuing
transition from analog to digital systems.

are the Heartbeat!"

    Script: (Ilhan Refioglu) (see "Business--Industry Background--The Components
Responsible for System Performance--The Role of Timing Devices in Electronic
Systems") Electronic systems generate and manipulate electrical signals using
primarily four types of components. These components include: control integrated
circuits, such as microprocessors and controllers, memory integrated circuits,
logic integrated circuits, which control the transfering, buffering and routing
of data; and timing devices. The components of these electronic systems must
continue to increase in performance in order to enable the continued development
of higher performance systems. Timing devices enable communication among the
components within systems as well as between systems. For proper communication
between devices, their input and output signals must be coordinated. Timing
devices are often described as providing the "heartbeat" of a system, as they

Performance, High Speed, Low Cost, Portability"

    Script: (Ilhan Refioglu) (see "Prospectus Summary, Business--Industry
Background--The Growing Importance of EMI") High performance computing,
communications and consumer electronics systems operate at high frequencies and,
as a result, emit elevated levels of electromagnetic interference, or EMI.
Because EMI disrupts the operations of cellular phones, televisions and other
communications systems, manufacturers of electronic equipment must reduce EMI to
remain in compliance with EMI regulations established by the FCC. Manufacturers
have employed a variety of costly and time consuming methods to reduce EMI, such
use of shielding material. Using innovative integrated circuits, systems
manufacturers can achieve EMI reduction in a timely and cost-effective manner.

    Script: (Ilhan Refioglu) (see "Prospectus Summary, Business--Industry
Background--Industry Demands") In order to meet the demand for higher
performance systems in the computing, communications and consumer electronics
markets, systems manufacturers require high performance integrated circuits with
programmable feature that allow them to rapidly design and test systems
assisting them in meeting their time-to-market and cost objectives. In addition,
manufacturers need flexible solutions that reduce the overall size and cost of
ownership of timing devices in their systems, while at the same time,
effectively handling some of the associated system performance issues. The
increasing system-wide EMI emissions that result from higher-frequency
integrated circuits have compelled system designers to develop and implement new
ways to further reduce these emissions. These factors all increase the need for
very high performance timing, EMI reduction and logic circuits with outstanding
performance specifications. Integrated circuit vendors are further required to
accomplish these tasks in a cost-effective manner that responds flexibly to
specific customer needs.

VISUAL 12: FINANCIAL SUMMARY

    Imagery: Border and Company logo. Quarterly results of Operations (June 30,
1998--June 30, 2000).

    Visual Text: Title: Financial Summary. "Quarterly Results of Operations"
table.

    Script: (Judy Signorino) (See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Overview" and "--Quarterly
Results of Operations"). We were founded in 1972 as a supplier of semi-custom
gate-array integrated circuits. In 1991, we entered the timing device market. We
introduced our first EMI reduction circuits in 1994, our first zero delay
buffers in fiscal 2000, and our initial line of high performance logic chips in
fiscal 2001.

    In 1997, we decided to focus our efforts on establishing a leadership
position in the timing device market and discontinued production of semi-custom
gate-array integrated circuits. At that time, we also decided to outsource all
wafer fabrication to independent foundries and discontinued operation of our own
wafer fabrication facility. All fixed assets related to our wafer fabrication
facility were sold, and the $1.4 million loss on the transaction was recorded in
fiscal 1998.

                                      A-6
<PAGE>
    In December 1997, we recapitalized our company, resulting in a group of
investors acquiring a 92% equity interest in our company.

    The following table sets forth unaudited statement of operations data for
each of the nine quarters ended June 30, 2000. This information has been derived
from our unaudited financial statements. These unaudited quarterly results
should be read in conjunction with the financial statements and notes thereto
appearing elsewhere in the prospectus.

    Our quarterly operating results have been affected by seasonal factors.
Original equipment manufacturers that purchase our integrated circuits for
incorporation into personal computers and consumer electronics typically
increase their purchases during the pre-year-end holiday period. As a result,
our revenues have historically peaked in the second and third quarter of each
fiscal year and declined in the fourth quarter of the fiscal year. We expect
these seasonal fluctuations to continue for the foreseeable future. The
increases in quarterly revenue from one fiscal year to the next were primarily
due to increased unit shipments as the result of new customer design wins.

    Gross margins in each quarter in fiscal 2000 have improved over the
corresponding quarter in fiscal 1999 due to a shift in product mix toward our
higher-margin EMI reduction and zero delay buffer integrated circuits and to
reductions in per unit manufacturing costs. Gross margins have varied on a
sequential quarterly basis due to seasonal revenue levels and quarterly
fluctuations in product mix.

    Research and development expenses increased primarily due to the hiring of
additional development personnel and consultants and an increase in prototyping
costs. The high expenditures in the quarters ended March 31, 2000 and
December 31, 1998 were due to unusually large numbers of prototypes delivered
during those quarters.

    Selling, general and administrative expenses fluctuate primarily as the
result of sales commissions, which are based on quarterly revenue. The unusually
high expenditures in the quarters ended March 31, 2000 and June 30, 2000 were
related to the expansion of our direct international sales force and the hiring
of additional applications engineers.

    This was a summary of our financial performance--now back to Ilhan.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 145 of the Delaware General Corporation Law permits indemnification
of officers, directors and other corporate agents under certain circumstances
and subject to certain limitations. The Registrant's Certificate of
Incorporation and Bylaws provide that the Registrant shall indemnify its
directors, officers, employees and agents to the full extent permitted by
Delaware General Corporation Law, including in circumstances in which
indemnification is otherwise discretionary under Delaware law. In addition, the
Registrant intends to enter into separate indemnification agreements
(Exhibit 10.1) with its directors and officers which would require the
Registrant, among other things, to indemnify them against certain liabilities
which may arise by reason of their status or service (other than liabilities
arising from willful misconduct of a culpable nature). The Registrant also
intends to maintain director and officer liability insurance, if available on
reasonable terms. These indemnification provisions and the indemnification
agreements may be sufficiently broad to permit indemnification of the
Registrant's officers and directors for liabilities (including reimbursement of
expenses incurred) arising under the Securities Act.

    The Underwriting Agreement (Exhibit 1.1) provides for indemnification by the
Underwriters of the Registrant and its officers and directors for certain
liabilities arising under the Securities Act, or otherwise.

ITEM 17. UNDERTAKINGS.

(1) The undersigned Registrant hereby undertakes to provide to the underwriters
    at the closing specified in the Underwriting Agreement certificates in such
    denominations and registered in such names as required by the underwriters
    to permit prompt delivery to each purchaser.

(2) Insofar as indemnification by the Registrant for liabilities arising under
    the Securities Act may be permitted to directors, officers and controlling
    persons of the Registrant pursuant to the foregoing provisions, or
    otherwise, the Registrant has been advised that in the opinion of the
    Commission such indemnification is against public policy as expressed in the
    Securities Act, and is therefore unenforceable. In the event that a claim
    for indemnification against such liabilities (other than the payment by the
    registrant of expenses incurred or paid by a director, officer, or
    controlling person of the registrant in the successful defense of any
    action, suit or proceeding) is asserted by such director, officer or
    controlling person in connection with the securities being registered
    hereunder, the Registrant will, unless in the opinion of its counsel the
    matter has been settled by controlling precedent, submit to a court of
    appropriate jurisdiction the question whether such indemnification by it is
    against public policy as expressed in the Securities Act and will be
    governed by the final adjudication of such issue.

(3) The undersigned Registrant hereby undertakes that:

        (a) For purposes of determining any liability under the Securities Act,
    the information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in the form
    of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective; and

        (b) For the purpose of determining any liability under the Securities
    Act, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at the time shall be
    deemed to be the initial bona fide offering thereof.
