PART I

ITEM 1. BUSINESS

Pericom Semiconductor Corporation (the "Company" or "Pericom") designs, develops
and markets high-performance interface integrated circuits ("ICs") used in many
of today's advanced electronic systems. Interface ICs, such as interface logic,
switches and clock management products, transfer, route and time electrical
signals among a system's microprocessor, memory and various peripherals and
between interconnected systems. High-performance interface ICs, which enable
high signal quality, are essential for the full utilization of the available
speed and bandwidth of advanced microprocessors, memory ICs, local area networks
("LANs") and wide area networks ("WANs"). Pericom focuses on high-growth and
high-performance segments of the notebook computing, servers, networking and
telecommunications markets, in which advanced system designs require interface
ICs with high-speed performance, reduced power consumption, low-voltage
operation, small size and higher levels of integration.

Pericom has combined its extensive design technology and applications knowledge
with its responsiveness to the specific needs of electronic systems developers
to become a competitive supplier of interface ICs. The Company has evolved from
one product line in fiscal 1992 to four currently -- SiliconInterface,
SiliconSwitch, SiliconClock and SiliconConnect(TM) -- with a goal of providing
an increasing breadth of interface IC solutions to its customers. Pericom
currently offers over 350 standard products, of which 113 were introduced during
the twelve months ended June 30, 1999. The Company's customers and OEM end users
include 3Com Corporation, Apple Computer, Inc., Ascend Communications, Inc.,
Avid Technology, Inc., Cabletron Systems, Inc., Canon, Inc., Celistica, Cisco
Systems, Inc., Compaq Computer Corporation, Dell Computer, Fujitsu, Hewlett-
Packard Company, Hitachi Ltd., International Business Machines Corporation,
Intel Corporation, Inventec, Inc., Lexmark International Inc., Lucent, Motorola,
Nortel, Quanta, Qualcom, Smart Modular Technologies Inc., Solectron Technology
Corporation, Sony Corporation, Toshiba Corporation, and Xerox.


INDUSTRY BACKGROUND

OVERVIEW

The presence of electronic systems and subsystems permeates our everyday life,
as evidenced by the growth of the personal computer, mobile communications,
networking and consumer electronics markets. The growth of these markets has
been driven by systems characterized by ever-improving performance, flexibility,
reliability and multi-functionality, as well as decreasing size, weight and
power consumption. Advances in ICs through improvements in semiconductor
technology have contributed significantly to the increased performance of, and
demand for, electronic systems and to the increasing representation of ICs as a
proportion of overall system cost. This technological progress has occurred at
an accelerating pace, while the cost of electronic systems has remained steady
or declined.

The development of high-performance personal computers, the requirement for
higher network performance and the increased level of connectivity among
different types of electronic devices have driven the demand for high-speed,
high-performance interface circuits to handle the transfer, routing and timing
of digital and analog signals at high speeds with minimal loss of signal
quality. High-speed signal transfer is essential to fully utilize the speed and
bandwidth of the microprocessor, the memory and the LAN or WAN. High signal
quality is equally essential to achieve optimal balance between high data
transmission rates and reliable system operation. Without high signal quality,
transmission errors occur as bandwidth increases. Market requirements for
interface circuits are driven by the same market pressures as those imposed on
microprocessors, including higher speed, reduced power consumption, lower-
voltage operation, smaller size and higher levels of integration.

Pericom's interface products serve to increase system bandwidth in applications
such as servers, network switches and routers, storage area networks, wireless
basestations, and notebook computers. Bandwidth can

1


be increased by widening the datapath (widening the pipe), increasing the clock
rate (increase the flowrate through the pipe) or allowing multiple, simultaneous
transactions on the bus using a crossbar switch. Pericom is pioneering
technology in each of these areas.

The problems associated with signal quality that must be addressed by the
interface ICs are magnified by increases in the speeds at which interface ICs
must transfer, route and time electrical signals, the number of interconnected
devices that send or receive signals and the variety of types of signals
processed by the interface ICs. The most significant performance challenges
faced by designers of interface ICs are the requirements to transfer signals at
high speed with low propagation delay, minimize signal degradation caused by
"noise," "jitter," and "skew" and reduce electromagnetic interference ("EMI").
Minimizing propagation delay sources of signal degradation and interference is
needed to enable today's state-of-the-art electronic systems to function.

Pericom believes that several major market trends make reliable operations of
systems at high frequency and high data transfer rates critical. Internet and
high-performance network applications continue to push for more data bandwidth
on system buses and across system boundaries. Computer and networking system
clock frequencies continue to increase at a very rapid rate, shortening the time
available to perform data transfers. While the data transfer rate has typically
increased every few years, the continuing desire for higher system reliability
with minimal system downtime creates increasing pressure to achieve lower data
error rates. Increasing system-wide EMI emissions resulting from higher-
frequency ICs compels system designers to develop and implement new ways to
further reduce these emissions. These factors all increase the need for very
high-speed interface circuits with outstanding performance specifications.

With processing power continuing to double every 18 months (Moore's law) the
speed at which microprocessors can access memory becomes the system bandwidth
constraint in high-speed computing. The Company has developed solutions with
Intel and Rambus to support higher speed processor-memory interfacing to support
the PC133 and Direct Rambus standards, both on the system motherboard and memory
modules.

In server applications, Pericom supports higher system bandwidth through the use
of bus switches to isolate the system's memory modules from the bus when they
are not being addressed. The Company's interface products are also used to
enable live insertion of PCI boards ("hot swapping"). This prevents system
downtime when boards need to be replaced. Pericom has similar products for hot-
docking notebook computers and its products are used in virtually every notebook
computer.

In all new high-bandwidth systems data transfer needs to be synchronized,
creating a high demand for clock products. Pericom's clock products provide all
the precise timing signals needed to ensure reliable data transfer at high
speeds in applications ranging from notebook computers to network switches. As
systems continue to grow in processing power and complexity the demand for these
products will accelerate. The demand for higher precision will also continue to
increase as timing margins shrink in higher bandwidth systems.

Another trend evident in the communications (data and voice) and the storage
market is the trend to parallel processing to increase performance. The need to
interface several processors to one another and to memory components is driving
customers to develop new switching fabrics. The Company has responded to this
opportunity with the development of a high-density crossbar switch technology
which enables point-to-point connection of multiple processors to boost
bandwidth by an order of magnitude.

Pericom also believes that electronic systems designers and OEMs have
increasingly required solutions to the technical challenges described above in
order to take advantage of continuing speed and performance enhancements in
microprocessor and memory ICs. These customers have also continued to migrate
from single-part vendors to suppliers who can provide multiple parts for their
systems, both to reduce the number of vendors they must deal with and to address
interoperability requirements among the interface ICs within the system. Due to
the short design times and product life cycles these customers face for their
own products, they are requiring rapid response time and part availability from
interface IC vendors. Interface IC

2


vendors are further required to accomplish these tasks in a cost-effective
manner that flexibly responds to specific customer needs.


PRODUCTS

The Company has used its expertise in high-performance digital, analog and
mixed-signal IC design, its re-usable core cell library and its modular design
methodology to achieve a rapid rate of new product introductions. The Company
has evolved from one product line in fiscal 1992 to four product lines
currently, with a goal of providing an increasing breadth of product solutions
to its customers. Within each product line, the Company has continued to
introduce products with higher performance, higher levels of integration, and
new features and options.

SiliconInterface

Through its SiliconInterface product line, Pericom offers a broad range of high-
performance 5-volt, 3.3-volt, and 2.5-volt CMOS logic interface circuits. These
products provide logic functions to handle data transfer between microprocessors
and memory, bus exchange, backplane interface, and other logic interface
functions where high-speed, low-power, low-noise and high-output drive
characteristics are essential. The Company's thin and tight-lead-pitch packages
allow significant reduction in board space and provide enhanced switching
characteristics. The Company has two patents that relate to certain
SiliconInterface products: one that relates to mixed-voltage operations that are
scaleable for future generations of low-voltage logic families, and one that
relates to a high-speed, low-noise input/output buffer design. The
SiliconInterface product line is used in a wide array of systems applications,
including notebook computers, high-speed network hubs, routers and switches and
multimedia systems.

5-VOLT INTERFACE LOGIC. The Company's high-speed 5-volt interface logic products
in 8-, 16- and 32-bit configurations address specific system applications,
including a "Quiet Series" family for high-speed, low-noise, point-to-point data
transfer in computing and networking systems and a "Balanced Drive" family with
series resistors at output drivers to reduce switching noise in high-capacitive
load switching in the main and cache memories of high-performance computers.

3.3-VOLT INTERFACE LOGIC. Pericom's 3.3-volt interface logic products in 8 to 24
bit configurations address a range of cost and performance requirements. The
Company's 3.3-volt ALVC, LPT, LCX and FCT3 interface logic families offer a
comprehensive range of performance at very low power. The ALVC, LPT and LCX
families allow customers the flexibility to use certain Pericom 3.3-volt
products in pure 3.3-volt or mixed 3.3/5-volt designs. Because a full range of
3.3-volt components is not always available, this flexibility is important as
computer and networking designs make the transition from 5 volts to 3.3 volts.
ALVC, a leading-edge performance family that targets high-speed computer and
networking designs, offers bus hold and 5-volt I/O tolerance options. With 55
products in the family, the Company now offers one of the broadest portfolios of
ALVC logic in the industry. LPT is a mid-range performance family and the
industry's first 3.3-volt CMOS logic family with 5-volt I/O tolerance. LCX is a
relatively slow-speed family that is targeted for low-cost applications. FCT3 is
a mid-range performance family that can interface only with 3.3-volt components.
Increasing networking, PC and memory module manufacturers are demanding
application specific logic products. Pericom believes it is well positioned to
serve this need using its ASIC design methodology and existing cell designs to
achieve rapid product development.

2.5-VOLT INTERFACE LOGIC. Pericom has three new logic families to address 2.5and
1.8 volt operation. The ALVTC is a high-drive family offering sub 2.5 nanosecond
propagation delays and the lowest power consumption in its class. The AVC
family offers a lower balanced drive with a propagation delay of less than 2
nanoseconds. The VCX family also offers balanced drive but is optimized for
low-noise operation. All three families can support 1.8 to 3.3 volt operation.

3


SiliconSwitch

Through its SiliconSwitch product line, Pericom offers a broad range of high-
performance ICs for switching digital and analog signals. The ability to switch
or route high-speed digital or analog signals with minimal delay and signal
distortion is a critical requirement in many high-speed computers, networking
and multimedia applications. Historically, systems designers have used
mechanical relays, solid-state relays and analog switches, which have
significant disadvantages compared to IC switches: mechanical relays are bulky,
dissipate significant power and have very low response times; solid-state relays
are expensive and dissipate significant power; and traditional analog switches
have relatively high resistance that can cause significant signal distortion.

DIGITAL SWITCHES. The Company offers a family of digital switches in 8-, 16- and
32-bit densities that address the switching needs of high-performance systems.
These digital switches offer performance and cost advantages over traditional
switch functions, offering low on-resistance (less than 5 ohms), low propagation
delay (less than 250 picoseconds), low standby power (less than 1 microamp) and
series resistor options that support low EMI emission requirements. Applications
for the Company's digital switches include 5-volt to 3.3-volt signal
translation, high-speed data transfer and switching between microprocessors and
multiple memories, and hot plug interfaces in notebook and desktop computers,
servers and switching hubs and routers. During fiscal 1999, the Company
developed a family of application specific switches to support PCI "hot-
plugging" and GTL termination in server applications. Two families of 3.3-volt
switches were also introduced offering industry leadership performance in terms
of their switching times and low capacitance for bus isolation applications.

ANALOG SWITCHES. The Company offers a family of analog switches for low-voltage
(2- to 5-volt) applications such as multimedia audio and video signal switching
with enhanced characteristics such as low power, high bandwidth, low crosstalk
and low distortion to maintain analog signal integrity. Traditional analog
switches cause unacceptable levels of distortion due to high on-resistance. The
Company's analog switches have significantly lower on-resistance, resulting in
significant improvement in bandwidth and distortion. This allows the Company's
analog switches to be used for state-of-the-art video and audio switching
applications where traditional analog switches cannot be used. To support space-
constrained applications, such as wireless handsets and Global Positioning
Systems ("GPS") receivers, several of these switches have recently been
introduced in the tiny SOT-23 and SC70 packages. To complement this low-voltage
family the Company also offers a higher voltage (17 volt) analog switch family
for applications requiring higher signal range, such as instrumentation,
telecommunications and industrial control. The addition of this family
significantly strengthens Pericom's position in the analog switch market.

LAN SWITCHES AND VIDEO SWITCHES. The Company offers a line of application-
specific standard product ("ASSP") switches for specific applications. These
products include LANSwitches, which are used to switch among multiple LAN
protocols (e.g., Ethernet, FastEthernet and Token Ring) on networking systems,
and video switches, which are used in graphic and multimedia systems to switch
among different video and audio sources at very high frequencies with minimal
distortion, hence preserving high video and audio fidelity.

SiliconClock

Through its SiliconClock product line, Pericom offers a broad range of general-
purpose solutions including clock buffers, PLL-based zero-delay clock generators
and ASSP PLL-based frequency synthesizer products for Pentium II, Pentium III
and Celeron processor systems, as well as a number of ASSP clock products for
laser printers, networking, and set-top box applications. As system designers
use microprocessors and memories that run at increasingly high frequencies,
there is a demand for correspondingly reliable clock management circuits to
generate and distribute high-precision, high-frequency timing control signals
for advanced computer, networking, multimedia and embedded applications. To
enable the reliable operations

4


of these ICs with precise timing, the clock circuits need to have short
propagation delay, low jitter and low pin-to-pin signal skew.

CLOCK BUFFERS AND ZERO-DELAY CLOCK GENERATORS. Clock buffers receive a digital
signal from a frequency source and create multiple copies of the signal for
distribution across system boards. Pericom offers 3.3-volt and 5-volt clock
buffers for high-speed, low-skew applications in computers and networking
equipment. PLL-based clock generators, also known as zero-delay clocks,
virtually eliminate propagation delays by synchronizing the clock outputs with
the incoming frequency source. Pericom's 5-volt and 3.3-volt zero-delay clock
generators offer frequencies of up to 134 MHz for applications in networking
switches, routers and hubs, computer servers, PCI bridges and SDRAM modules.
Pericom supports the latest industry standard PC133 and PC100 SDRAM registered
DIMM memory modules with zero delay clock buffers to drive the SDRAM clocks, and
ALVC and AVC logic buffers to drive the address lines.

CLOCK FREQUENCY SYNTHESIZERS. Clock frequency synthesizers use single or
multiple PLLs to generate various output frequencies using a crystal oscillator
as an input frequency source. Clock frequency synthesizers are used to provide
critical timing signals to microprocessors, PCI buses, SDRAM and peripheral
functions. Pericom's PLL-based clock synthesizers support Pentium II, Pentium
III and Celeron microprocessors and their associated integrated chipsets. These
clock generators are designed with an emphasis on minimizing jitter and power
consumption. In addition, most of the products come with integrated serial I2C
serial link communications and options for spread-spectrum selection that meet
low EMI requirements for mobile and desktop PC motherboards. Pericom recently
introduced an integrated 100 and 133MHz clock generator and buffer to support
the latest 810 ("Whitney") and 810e chipset for the Celeron processor. The
Company also has a range of integrated products for the notebook computer market
segment and is an active participant in the development of Intel defined
technology for the next generation PC and server platforms. To support the
latest Direct Rambus memory technology the Company has developed a 400MHz clock
generator to support the synchronous transfer of data in the Rambus RIMM memory
module. The Company's PLL-based laser printer clock provides a cost-effective
solution for high-speed, high-resolution video clock generation at 40 MHz for
low-cost color laser printer controllers and at 80 MHz for high-speed color
laser printer controllers. The Company also offers modem clocks to support 28.8K
and 56K rack-mount modem designs.

FLEX CLOCK. To support embedded processor and data transmission operations,
telecom and datacom applications often require unique combinations of
frequencies on the system board. Traditionally, such requirements have been
handled by the simultaneous use of several crystal oscillators. This approach is
costly, however, and requires significant board space. Also, certain uncommon
frequencies require very long purchase order lead times. Supporting quick-turn
customer prototyping as well as volume production requirements, Pericom's
FlexClock product offers customers programmable PLL-based clock synthesizers
that provide multiple customer-specified frequencies in a single IC with short
lead time and with fast factory programming of custom requested frequencies.

SiliconConnect(TM)

The SiliconConnect(TM) product line is the newest and offers the highest
complexity and integration among the Company's products. It consists of a family
of Low Voltage Differential Signaling (LVDS) drivers, receivers, and
transceivers, cross-bar switches, and PCI to PCI bridge products currently in
development.

To support higher system bandwidth at acceptable noise and power levels
customers are increasingly moving to serial rather than parallel architectures
and using differential signaling to reduce noise and electromagnetic
interference (EMI). Pericom has responded to this need with the development of a
family of drivers, receivers and transceivers offering data rates of 400 Mbps
(Megabits per second), allowing point-to-point connections over distances
greater than 10 meters. This new low-voltage differential signaling (LVDS)
standard offers a number of improvements over the older ECL (Emitter-Coupled
Logic) and PECL (Pseudo Emitter-Coupled Logic) in applications requiring lower
power consumption and noise.

5


Another technology recently introduced by Pericom to support higher bandwidth is
cross-bar switching to allow multiple processors and memory modules to
communicate on point-to-point connections across a shared bus. The first product
in the family is a 10-port 18-bit switch which supports a data rate up to 264
Gigabytes per second.

The Company also has a 3-port PCI to PCI bridge product in development. This
product can support input/output expansion on the PCI bus in applications
ranging from network routers to memory storage and server applications.

The Company is continuing to enhance and refine the offerings in its existing
product lines, while working to add next-generation products which address new
market opportunities on a timely basis. The failure of the Company to complete
and introduce new products in a timely manner at competitive price/performance
levels would materially and adversely affect the Company's business and results
of operations. See "Factors That May Affect Future Results -- Technological
Changes; Dependence on New Products."

The Company's customers include a broad range of end users and OEMs in the
computer, peripherals, networking and contract manufacturing markets. In fiscal
1997, sales to Harris and IBM accounted for approximately 17% and 14%,
respectively, of the Company's net revenues, and sales to the Company's top five
customers accounted for approximately 47% of net revenues. In fiscal 1998, sales
to Techmosa, a

6


distributor in Taiwan, accounted for 11% of net revenues, and sales to the
Company's top five customers accounted for 36% of net revenues. In fiscal 1999,
sales to Techmosa accounted for 14% of net revenues, and sales to the Company's'
top five customers accounted for 36% of net revenues. See "Factors That May
Affect Future Results -- Customer Concentration."

Contract manufacturers have become important customers for the Company as
systems designers in the Company's target markets are increasingly outsourcing
portions of their manufacturing. In addition, these contract manufacturers are
playing an increasingly vital role in determining which vendors' ICs are
incorporated into new designs.


DESIGN AND PROCESS TECHNOLOGY

The Company's design efforts focus on the development of high-performance
digital, analog and mixed-signal ICs. To minimize design cycle times of high-
performance products, the Company utilizes a modular design methodology that has
enabled it to produce many new products each year and to meet its customers'
need for fast time-to-market response. This methodology uses state-of-the-art
computer-aided design software tools such as HDL description, logic synthesis,
full-chip mixed-signal simulation, and automated design layout and verification
using Pericom's library of high-performance digital and analog core cells. This
family of core cells has been developed over several years and contains high-
performance, specialized digital and analog functions not available in
commercial ASIC libraries. Among these cells are the Company's proprietary
mixed-voltage I/O cells, high-speed, low-noise I/O cells, analog and digital
PLLs, charge pumps and datacom transceiver circuits. Pericom has been granted
thirteen U.S. patents relating to its circuit designs and has several U.S. and
foreign patent applications pending. Another advantage of this modular design
methodology is that it allows the application of final design options late in
the wafer manufacturing process to determine a product's specific function. This
option gives the Company the ability to use pre-staged wafers, which
significantly reduces the design and manufacturing cycle time and enables the
Company to respond rapidly to a customer's prototype needs and volume
requirements.

The Company utilizes advanced CMOS processes to achieve optimal performance and
die cost. The Company's process and device engineers work closely with its
independent wafer foundry partners to develop and evaluate new process
technologies. The Company's process engineers also work closely with circuit
design engineers to optimize the performance and reliability of its cell
library. The Company currently manufactures a majority of its products using 0.5
micron and 0.6 micron CMOS process technologies and is using an advanced 0.35
micron CMOS process, which has been qualified and is in production, in the
design of a number of its new products. The Company is also using a high-voltage
CMOS process developed by one of its foundry partners in the design of new
switch products.


SALES AND MARKETING

The Company markets and distributes its products through a worldwide network of
independent sales representatives and distributors. In fiscal years 1999, 1998
and 1997, international sales comprised 48%, 45% and 37%, respectively, of the
Company's net revenues. The Company has four regional sales offices in the
United States and has sales offices in Taiwan, Japan and Europe. The Company
also supports field sales design-in and training activities with application
engineers. All marketing and product management personnel are located at the
Company's corporate headquarters in San Jose, California. See "Factors That May
Affect Future Results -- Risks of International Sales."

The Company focuses its marketing efforts on product definition, new product
introduction, product marketing, advertising and public relations. The Company
actively seeks cooperative relationships in product development and product
marketing. For example, the Company recently signed an agreement with Lexmark
to license its spread spectrum technology and with Rambus to develop the Direct
Rambus Clock Generator IC. The Company uses advertising both domestically and
internationally to market its products independently and in cooperation with its
distributors. Pericom product information is available on its web

7


site, which contains technical information on all of its products and offers
design modeling support and sample-request capabilities online. The Company also
publishes and circulates technical briefs relating to its products and their
applications.

The Company has been ISO-9001 certified by the International Organization for
Standards for Quality Management after the Company successfully completed the
required Registration Assessment Audit with Underwriter's Laboratories, which
entails a rigorous quality assessment.

Pericom believes that contract manufacturing customers are strategically
important and employs sales and marketing personnel who focus on servicing these
customers and on expanding Pericom's product sales via these customers to OEMs.
In addition, Pericom uses programs such as EDI, bonded inventories and remote
warehousing to enhance its service and attractiveness to contract manufacturers.

Sales through domestic and international distributors were approximately 57%,
49% and 36% of the Company's net revenues in fiscal 1999, 1998 and 1997,
respectively. Major distributors in the United States include All American
Semiconductor, Bell Microproducts, Future Electronics, Interface Electronics, Nu
Horizons Electronics, and Pioneer Standard. Major international distributors
include Chin Shang Electronics Corp. (Taiwan), EPCO Technology Co., LTD
(Taiwan), Desner Electronics (Singapore), Internix (Japan), MCM (Japan) and
Techmosa (Taiwan). See "Factors That May Affect Future Results -- Reliance on
Distributors."


MANUFACTURING

The Company has adopted a fabless manufacturing strategy by subcontracting its
wafer production to independent wafer foundries. The Company has established
collaborative relationships with selected independent foundries and targets
additional foundry partners with which it can develop a strategic relationship
to the benefit of both parties. The Company believes that its fabless strategy
enables it to introduce high performance products quickly at competitive cost.
To date, the Company's principal manufacturing relationships have been with
Chartered Semiconductor Manufacturing Pte, Ltd. ("Chartered"), Taiwan
Semiconductor Manufacturing Corporation ("TSMC") and Lucky Goldstar ("LG"). The
Company provides Chartered with new product designs to be used for testing and
qualifying advanced manufacturing processes from development to production. In
exchange, Chartered provides the Company with wafer allocation and early access
to process technology. The Company has also used Austria Mikro Systeme GmbH
("AMS") as a foundry since 1992. Recently the Company qualified a 0.35micron
CMOS process at Chartered that is currently in production.

The Company relies on foreign subcontractors primarily for the assembly and
packaging of its products and, to a lesser extent, for the testing of its
finished products. Some of these subcontractors are the Company's single source
supplier for certain new packages. Although the Company believes that it is not
materially dependent upon any such subcontractor, changes in the Company's or a
subcontractor's business could cause the Company to become materially dependent
on a subcontractor. The Company has from time to time experienced difficulties
in the timeliness and quality of product deliveries from the Company's
subcontractors. Although delays experienced to date have not been material,
there can be no assurance that the Company will not experience similar or more
severe difficulties in the future. The Company generally purchases these single
or limited source components or services pursuant to purchase orders and has no
guaranteed arrangements with such subcontractors. There can be no assurance that
these subcontractors will continue to be able and willing to meet the Company's
requirements for any such components or services. Any significant disruption in
supplies from, or degradation in the quality of components or services supplied
by, these subcontractors, or any other circumstance that would require the
Company to qualify alternative sources of supply could delay shipments and
result in the loss of customers, or limitations or reductions in the Company's
revenues, or otherwise materially and adversely affect the Company's business
and results of operations. See "Factors That May Affect Future Results --
Dependence on Single or Limited Source Assembly Subcontractors."

RESEARCH AND DEVELOPMENT

The Company believes that the continued timely development of new interface ICs
is essential to maintaining its competitive position. Accordingly, the Company
has assembled a team of highly skilled engineers whose activities are focused on
the development of signal transfer, routing and timing technologies and
products. Research and development expenses in fiscal 1999, 1998, and 1997 were
$6.0 million, $5.1 million and $4.2 million, respectively.

The success of new products depends on many factors, including product
selection, timely completion of product development, ability to gain access to
advanced fabrication processes, achievement of acceptable wafer fabrication
yield, and the ability to secure sufficient wafer fabrication capacity. There
can be no assurance that the Company will be able to successfully identify new
product opportunities and timely develop and bring to market such new products.
Failure of the Company to complete, introduce and bring to volume production new
products in a timely manner and at competitive price/performance levels could
adversely affect the Company's results of operations. See "Factors That May
Affect Future Results -- Technological Change; Dependence on New Products."


INTELLECTUAL PROPERTY

In the United States, the Company holds fifteen patents covering certain aspects
of its product designs and has ten additional patent applications pending. The
Company expects to continue to file patent applications where appropriate to
protect its proprietary technologies; however, the Company believes that its
continued success depends primarily on factors such as the technological skills
and innovation of its personnel, rather than on its patents.

The Company's success depends in part on its ability to obtain patents and
licenses and preserve other intellectual property rights covering its products
and development and testing tools. Copyrights, mask work protection, trade
secrets and confidential technological know-how are also key elements of the
Company's business. There can be no assurance that any additional patents will
be issued to the Company or that the Company's patents or other intellectual
property will provide meaningful protection from competition. The Company may be
subject to or may initiate interference proceedings in the U.S. Patent and
Trademark Office, which can consume significant financial and management
resources. In addition to the foregoing, the laws of certain territories in
which the Company's products are or may be developed, manufactured or sold may
not protect the Company's products and intellectual property rights to the same
extent as the laws of the United States. The inability of the Company to protect
its intellectual property adequately could have a material adverse effect on its
business and results of operations.

The semiconductor industry is characterized by frequent litigation regarding
patent and other intellectual property rights, and there can be no assurance
that the Company will not be subject to infringement claims by other parties.
Any litigation, whether or not determined in favor of the Company, can result in
significant expense to the Company and can divert the efforts of the Company's
technical and management personnel from productive tasks. In the event of an
adverse ruling in any litigation involving intellectual property, the Company
might be required to discontinue the use of certain processes, cease the
manufacture, use and sale of infringing products, expend significant resources
to develop non-infringing technology or obtain licenses to the infringed
technology, and may suffer significant monetary damages, which could include
treble damages. In the event the Company attempts to license any allegedly
infringed technology, there can be no assurance that such a license would be
available on reasonable terms or at all. In the event of a successful claim
against the Company and the Company's failure to develop or license a substitute
technology on commercially reasonable terms, the Company's business and results
of operations would be materially and adversely affected. There can be no
assurance that potential infringement claims by other

9


parties (or claims for indemnity from customers resulting from any infringement
claims) will not materially and adversely affect the Company's business,
financial condition and results of operations.

The process technology used by the Company's independent foundries, including
process technology that the Company has developed with its foundries, can
generally be used by such foundries to produce their own products or to
manufacture products for other companies, including the Company's competitors.
In addition, the Company does not generally have the right to implement the
process technology used to manufacture its products with foundries other than
the foundry with which it has developed such process technology. See "Factors
That May Affect future Results -- Patents and Proprietary Rights."


EMPLOYEES

As of June 30, 1999, the Company had 188 full-time employees (18 are temporary
employees), including 36 in sales, marketing and customer support, 83 in
manufacturing, assembly and testing, 52 in engineering and quality assurance and
17 in finance and administration, including information systems. The Company has
never had a work stoppage and no employee is represented by a labor
organization. The Company considers its employee relations to be good.

The Company's future success will depend to a large extent on the continued
contributions of its executive officers and other key management and technical
personnel, none of whom has an employment agreement with the Company and each of
whom would be difficult to replace. The Company does not maintain any key person
life insurance policy on any of such persons. The loss of the services of one or
more of the Company's executive officers or key personnel or the inability to
continue to attract qualified personnel could delay product development cycles
or otherwise have a material adverse effect on the Company's business, financial
condition and results of operations. See "Factors That May Affect Future Results
- -- Dependence on Key Personnel."


FACTORS THAT MAY AFFECT FUTURE RESULTS

In addition to other information contained in this Form 10-K, investors should
carefully consider the following factors that may affect future results. This
Form 10-K includes "forward-looking statements" within the meaning of Section
27A of the Securities Act and Section 21E of the Exchange Act. All statements
other than statements of historical fact are "forward-looking statements" for
purposes of these provisions, including any statements regarding projections of
earnings, revenues or other financial items; plans and objectives of management
for future operations; proposed new products or services; industry,
technological or market trends, Pericom's ability to address the need for
application specific logic products; Pericom's ability to respond rapidly to
customer needs; expanding product sales; the Company's costs and liabilities
related to and ability to mitigate potential Year 2000 issues; future economic
conditions or performance, and any statement of assumptions underlying any of
the foregoing. In some cases, forward-looking statements can be identified by
the use of terminology such as "may," "will," "expects," "plans," "anticipates,"
"estimates," "potential," or "continue," or the negative thereof or other
comparable terminology. Although the Company believes that the expectations
reflected in the forward-looking statements contained herein are reasonable,
there can be no assurance that such expectations or any of the forward-looking
statements will prove to be correct, and actual results could differ materially
from those projected or assumed in the forward-looking statements. The
Company's future financial condition and results of operations, as well as any
forward-looking statements, are subject to risks and uncertainties, including
but not limited to the factors set forth in factors that may affect future
results set forth below and elsewhere in this report. All forward-looking
statements and reasons why results may differ included in this Form 10-K are
made as of the date hereof, and the Company assumes no obligation to update any
such forward-looking statement or reason why actual results may differ.

LIMITED OPERATING HISTORY; POTENTIAL FLUCTUATIONS IN OPERATING RESULTS

The Company was founded in 1990 and has a limited history of operations, having
shipped its first products in volume in fiscal 1993. There can be no assurance
that any past levels of revenue growth or profitability can be sustained on a
quarterly or annual basis. The Company's expense levels are based in part on
anticipated future revenue levels, which can be difficult to predict. The
Company's business is characterized by short-term orders and shipment schedules.
The Company does not have long-term purchase agreements with any of its
customers, and customers can typically cancel or reschedule their orders without
significant penalty. The Company typically plans its production and inventory
levels based on forecasts, generated with input from customers and sales
representatives, of customer demand which is highly unpredictable and can
fluctuate substantially. If customer demand falls significantly below
anticipated levels, the Company's business, financial condition and results of
operations would be materially and adversely affected. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

The Company has experienced significant fluctuations in its quarterly operating
results in the past three fiscal years and could continue to experience such
fluctuations in the future. The Company's operating results are affected by a
wide variety of factors that could materially and adversely affect net revenues
and results of operations, including a decline in the gross margins of its
products, the growth or reduction in the size of the market for interface ICs,
delay or decline in orders received from distributors, the availability of
manufacturing capacity with the Company's wafer suppliers, changes in product
mix, customer acceptance of the Company's new products, the ability of customers
to make payments to the Company, the timing of new product introductions and
announcements by the Company and its competitors, increased research and
development expenses associated with new product introductions or process
changes, expenses incurred in obtaining and enforcing, and in defending claims
with respect to, intellectual property rights, changes in manufacturing costs
and fluctuations in manufacturing yields, and other factors such as general
conditions in the semiconductor industry. All of the above factors are difficult
for the Company to forecast, and these or other factors can materially and
adversely affect the Company's business, financial condition and results of
operations for one quarter or a series of quarters. The Company's expense levels
are based in part on its expectations regarding future sales and are fixed in
the short term to a large extent. Therefore, the Company may be unable to adjust
spending in a timely manner to compensate for any unexpected shortfall in sales.
Any significant decline in demand relative to the Company's expectations or any
material delay of customer orders could have a material adverse effect on the
Company's business, financial condition and results of operations. There can be
no assurance that the Company will be able to sustain profitability on a
quarterly or annual basis. In addition, it is possible that the Company's
operating results in future quarters may fall below the expectations of public
market analysts and investors, which would likely result in a material drop in
the market price of the Company's Common Stock. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."

Historically, selling prices in the semiconductor industry generally, as well as
for the Company's products, have decreased significantly over the life of each
product. The Company expects that selling prices for its existing products will
continue to decline over time and that average selling prices for new products
will decline significantly over the lives of these products. Declines in selling
prices for the Company's products, if not offset by reductions in the costs of
producing these products or by sales of new products with higher gross margins,
would reduce the Company's overall gross margins and could materially and
adversely affect the Company's business, financial condition and results of
operations. There can be no assurance that the Company will be able to reduce
production costs or to develop and market new products with higher gross
margins. See "Technological Change; Dependence on New Products," "Competition,"
" Semiconductor Industry Risks" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

DEPENDENCE ON INDEPENDENT WAFER FOUNDRIES

In fiscal 1996, 1997 and 1998 approximately 90% of the wafers for the Company's
semiconductor products were manufactured by Chartered. The remainder of the
Company's wafers were manufactured by AMS, LG, NJRC and TSMC. In fiscal 1999,
approximately 85% of the Company's wafers were purchased from

11


Chartered. The Company's reliance on independent wafer suppliers to fabricate
its wafers at their production facilities subjects the Company to such possible
risks as potential lack of adequate capacity and available manufactured
products, lack of control over delivery schedules and the risk of events
limiting production and reducing yields, such as fires or other damage to
production facilities or technical difficulties. Although, to date, the Company
has not experienced any material delays in obtaining an adequate supply of
wafers, there can be no assurance that the Company will not experience delays in
the future. Any inability or unwillingness of the Company's wafer suppliers
generally, and Chartered in particular, to provide adequate quantities of
finished wafers to meet the Company's needs in a timely manner or in needed
quantities would delay production and product shipments and have a material
adverse effect on the Company's business, financial condition and results of
operations.

At present, the Company purchases wafers from its wafer suppliers through the
issuance of purchase orders based on rolling six-month forecasts provided by the
Company, and such purchase orders are subject to acceptance by each wafer
foundry. The Company does not have long-term purchase agreements with any of its
wafer suppliers, each of which has the right to reduce or terminate allocations
of wafers to the Company. In the event that these suppliers were unable or
unwilling to continue to manufacture the Company's key products in required
volumes, the Company would have to identify and qualify additional foundries. In
any event, the Company's future growth will also be dependent upon its ability
to identify and qualify new wafer foundries. The qualification process can take
up to six months or longer, and there can be no assurance that any additional
wafer foundries will become available to the Company or will be in a position to
satisfy any of the Company's requirements on a timely basis. The Company also
depends upon its wafer suppliers to participate in process improvement efforts,
such as the transition to finer geometries, and any inability or unwillingness
of such suppliers to do so could delay or otherwise materially adversely affect
the Company's development and introduction of new products. Furthermore, sudden
shortages of raw materials or production capacity constraints can lead wafer
suppliers to allocate available capacity to customers other than the Company or
for internal uses, which could interrupt the Company's ability to meet its
product delivery obligations. Any significant interruption in the supply of
wafers to the Company would adversely affect the Company's operating results and
relations with affected customers. The Company's reliance on independent wafer
suppliers may also impact the length of the development cycle for the Company's
products, which may provide time-to-market advantages to competitors that have
in-house fabrication capacity.

Each of Chartered, TSMC, AMS, LG and NJRC is located outside the United States,
which exposes the Company to risks associated with international business
operations, including foreign governmental regulations, currency fluctuations,
reduced protection for intellectual property, changes in political conditions,
disruptions or delays in shipments and changes in economic conditions in the
countries where these foundries are located, each of which could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business -- Manufacturing."

TECHNOLOGICAL CHANGE; DEPENDENCE ON NEW PRODUCTS

The markets for the Company's products are characterized by rapidly changing
technology, frequent new product introductions and declining selling prices over
product life cycles. The Company's future success is highly dependent upon the
timely completion and introduction of new products at competitive
price/performance levels. The success of new products depends on a variety of
factors, including product selection, product performance and functionality,
customer acceptance, competitive pricing, successful and timely completion of
product development, sufficient wafer fabrication capacity and achievement of
acceptable manufacturing yields by the Company's wafer suppliers. There can be
no assurance that the Company will be able to successfully identify new product
opportunities and develop and bring to market such new products or that the
Company will be able to respond effectively to new technological changes or new
product announcements by others. In addition, the Company may experience delays,
difficulty in procuring adequate fabrication capacity for the development and
manufacture of such products or other difficulties in achieving volume
production of these products. The failure of the Company to complete and

12


introduce new products in a timely manner at competitive price/performance
levels would materially and adversely affect the Company's business, financial
condition and results of operations.

The Company has relied in the past and continues to rely upon its relationships
with manufacturers of high-performance systems for insights into product
development strategies for emerging system requirements. The Company believes it
will rely on these relationships more in the future as the Company focuses on
the development and production of application specific standard products. The
Company generally incorporates its new products into a customer's product or
system at the design stage. However, these design efforts, which can often
require significant expenditures by the Company, may precede the generation of
volume sales, if any, by a year or more. Moreover, the value of any design win
will depend in large part on the ultimate success of the customer's product and
on the extent to which the system's design accommodates components manufactured
by the Company's competitors. No assurance can be given that the Company will
achieve design wins or that any design win will result in significant future
revenues. To the extent the Company cannot develop or maintain such
relationships, its ability to develop well-accepted new products may be
impaired, which could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Business --
Products" and "Business Research and Development."

CUSTOMER CONCENTRATION

A relatively small number of customers and distributors has accounted for a
significant portion of the Company's net revenues in each of the past several
fiscal years and the Company expects this trend to continue for the foreseeable
future. In fiscal 1999, sales to one distributor accounted for approximately 14%
of the Company's net revenues, and sales to the Company's top five customers and
distributors accounted for approximately 36% of net revenues. The Company does
not have long-term purchase agreements with any of its customers. There can be
no assurance that the Company's current customers will continue to place orders
with the Company, that orders by existing customers will continue at the levels
of previous periods or that the Company will be able to obtain orders from new
customers. Loss of one or more of the Company's large customers, or a reduction
in the volume of orders placed by any of such customers, could materially and
adversely affect the Company's business, financial condition and results of
operations. See "-- Limited Operating History; Potential Fluctuations in
Operating Results," "Management's Discussion and Analysis of Financial Condition
and Results of Operations," "Business -- Customers" and "Business -- Sales and
Marketing."

COMPETITION

The semiconductor industry is intensely competitive. Significant competitive
factors in the market for high-performance ICs include product features and
performance, product quality, price, success in developing new products,
adequate wafer fabrication capacity and sources of raw materials, efficiency of
production, timing of new product introductions, ability to protect intellectual
property rights and proprietary information, and general market and economic
conditions. The Company's competitors include Cypress Semiconductor Corporation,
Integrated Circuit Systems, Inc., Integrated Device Technology, Inc., Maxim
Integrated Products, Inc., and Texas Instruments, Inc., most of which have
substantially greater financial, technical, marketing, distribution and other
resources, broader product lines and longer-standing customer relationships than
the Company. The Company also competes with other major or emerging companies
that sell products to certain segments of the markets addressed by the Company.
Competitors with greater financial resources or broader product lines may also
have greater ability than the Company to engage in sustained price reductions in
the Company's primary markets in order to gain or maintain market share.

The Company believes that its future success will depend on its ability to
continue to improve and develop its products and processes. Unlike the Company,
many of the Company's competitors maintain internal manufacturing capacity for
the fabrication and assembly of semiconductor products, which may provide such
competitors with more reliable manufacturing capability, shorter development and
manufacturing cycles and time-to-market advantages. In addition, competitors
with their own wafer fabrication facilities that are capable of producing
products with the same design geometries as those of the Company may be

13


able to manufacture and sell competitive products at lower prices. Introduction
of products by competitors that are manufactured with improved process
technology could materially and adversely affect the Company's business and
results of operations. As is typical in the semiconductor industry, competitors
of the Company have developed and marketed products having functionality similar
or identical to the Company's products, and the Company expects this trend to
continue in the future. To the extent the Company's products do not achieve
performance, price, size or other advantages over products offered by
competitors, the Company is likely to experience greater price competition with
respect to such products. The Company also faces competition from the makers of
microprocessors and other system devices, including application specific
integrated circuits ("ASICs") that have been and may be developed for particular
systems. These devices may include interface logic functions, which may
eliminate the need or sharply reduce the demand for the Company's products in
particular applications. There can be no assurance that the Company will be able
to compete successfully in the future or that competitive pressures will not
materially and adversely affect the Company's financial condition and results of
operations. Competitive pressures could also reduce market acceptance of the
Company's products and result in price reductions and increases in expenses that
could materially and adversely affect the Company's business, financial
condition and results of operations. See "-- Dependence on Independent Wafer
Foundries," "-- Dependence on Single or Limited Source Assembly Subcontractors,"
"Business -- Manufacturing" and "Business -- Competition."

VARIATION IN PRODUCTION YIELDS

The manufacture and assembly of semiconductor products is highly complex and
sensitive to a wide variety of factors, including the level of contaminants in
the manufacturing environment, impurities in the materials used and the
performance of manufacturing personnel and production equipment. In a typical
semiconductor manufacturing process, silicon wafers produced by the foundry are
sorted and cut into individual die that are then assembled into individual
packages and tested for performance. The Company's wafer fabrication suppliers
have from time to time experienced lower-than-anticipated yields of good die, as
is typical in the semiconductor industry. In the event of such decreased yields,
the Company would incur additional costs to sort wafers, an increase in average
cost per usable die and an increase in the time to market for its products.
These conditions could reduce the Company's net revenues and gross margin, and
have an adverse effect on the Company's business and results of operations, and
relations with affected customers. No assurance can be given that the Company or
its suppliers will not experience yield problems in the future which could
result in a material adverse effect on the Company's business and results of
operations. See "Business -- Manufacturing."

SEMICONDUCTOR INDUSTRY RISKS

The semiconductor industry has historically been cyclical and periodically
subject to significant economic downturns, characterized by diminished product
demand, accelerated erosion of selling prices, overcapacity and rapidly changing
technology and evolving industry standards. Accordingly, the Company may in the
future experience substantial period-to-period fluctuations in business and
results of operations due to general semiconductor industry conditions, overall
economic conditions or other factors. The Company's business is also subject to
the risks associated with the effects of legislation and regulations relating to
the import or export of semiconductor products. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Business --
Manufacturing," "Business -- Sales and Marketing" and "Business -- Competition."

RELIANCE ON DISTRIBUTORS; PRODUCT RETURNS

Sales through domestic and international distributors represented 36%, 49% and
57% of the Company's net revenues in fiscal 1997, 1998 and 1999, respectively.
The Company's distributors are not subject to minimum purchase requirements, may
reduce or delay orders periodically due to excess inventory and can discontinue
selling the Company's products at any time. The Company recognizes revenue and
related gross profit from sales of products through distributors when shipped.
Domestic distributors are generally permitted a return allowance of 10% of their
net purchases every six months. Although the Company believes that, to date, it
has provided adequate allowances for exchanges, returns, price protection and
other

14


concessions and, to date, amounts incurred have not been material, there can be
no assurance that actual amounts incurred will not exceed the Company's
allowances, particularly in connection with the introduction of new products,
enhancements to existing products or price reductions. The Company's
distributors typically offer competing products. The loss of one or more
distributors, or the decision by one of the distributors to reduce the number of
the Company's products offered by such distributor or to carry the product lines
of the Company's competitors, could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Sales and Marketing."

MANAGEMENT OF GROWTH

The Company has recently experienced and may continue to experience growth in
the number of its employees and the scope of its operations, resulting in
increased responsibilities for management personnel. To manage recent and
potential future growth effectively, the Company will need to continue to
implement and improve its operational, financial and management information
systems and to hire, train, motivate and manage a growing number of employees.
The future success of the Company also will depend on its ability to attract and
retain qualified technical, marketing and management personnel, particularly
highly skilled design, process and test engineers, for whom competition is
intense. In particular, the current availability of qualified engineers is
limited, and competition among companies for skilled and experienced engineering
personnel is very strong. During strong business cycles, the Company expects to
experience continued difficulty in filling its needs for qualified engineers and
other personnel. The Company has been and is now in the later stages of
implementing a new management information system. There can be no assurance that
the Company will not encounter difficulties as it continues to integrate this
new system into its operations. There can be no assurance that the Company will
be able to achieve or manage effectively any such growth, and failure to do so
could delay product development cycles or otherwise have a material adverse
effect on the Company's business, financial condition and results of operations.

DEPENDENCE ON KEY PERSONNEL

The Company's future success will depend to a large extent on the continued
contributions of its executive officers and other key management and technical
personnel, none of whom has an employment agreement with the Company and each of
whom would be difficult to replace. The Company does not maintain any key person
life insurance policy on any such persons. The loss of the services of one or
more of the Company's executive officers or key personnel or the inability to
continue to attract qualified personnel could delay product development cycles
or otherwise have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Employees" and
"Management."

PATENTS AND PROPRIETARY RIGHTS

The Company's success depends in part on its ability to obtain patents and
licenses and preserve other intellectual property rights covering its products
and development and testing tools. In the United States, the Company holds
fifteen patents covering certain aspects of its product designs and has ten
additional patent applications pending. Copyrights, mask work protection, trade
secrets and confidential technological know-how are also key elements of the
Company's business. There can be no assurance that any additional patents will
be issued to the Company or that the Company's patents or other intellectual
property will provide meaningful protection from competition. The Company may be
subject to or may initiate interference proceedings in the U.S. Patent and
Trademark Office, which can consume significant financial and management
resources. In addition to the foregoing, the laws of certain territories in
which the Company's products are or may be developed, manufactured or sold may
not protect the Company's products and intellectual property rights to the same
extent as the laws of the United States. The inability of the Company to protect
its intellectual property adequately could have a material adverse effect on its
business, financial condition and results of operations.

The process technology used by the Company's independent foundries, including
process technology that the Company has developed with its foundries, can
generally be used by such foundries to produce their own products or to
manufacture products for other companies, including the Company's competitors.
In

15


addition, the Company does not generally have the right to implement the process
technology used to manufacture its products with foundries other than the
foundry with which it has developed such process technology. See "Business --
Intellectual Property."

RISKS RELATED TO INTERNATIONAL SALES

Sales outside of the United States accounted for approximately 37%, 45% and 48%
of the Company's net revenues in fiscal 1997, 1998 and 1999, respectively. The
Company expects that export sales will continue to represent a significant
portion of net revenues. The Company intends to expand its operations outside of
the United States, which will require significant management attention and
financial resources and further subject the Company to international operating
risks. These risks include unexpected changes in regulatory requirements, delays
resulting from difficulty in obtaining export licenses for certain technology,
tariffs and other barriers and restrictions, and the burdens of complying with a
variety of foreign laws. The Company is also subject to general geopolitical
risks in connection with its international operations, such as political and
economic instability and changes in diplomatic and trade relationships. In
addition, because the Company's international sales are denominated in U.S.
dollars, increases in the value of the U.S. dollar could increase the price in
local currencies of the Company's products in foreign markets and make the
Company's products relatively more expensive than competitors' products that are
denominated in local currencies, and there can be no assurance that the Company
will not be materially and adversely affected by fluctuating exchange rates.
There can be no assurance that regulatory, geopolitical and other factors will
not materially and adversely affect the Company's business, financial condition
and results of operations in the future or require the Company to modify its
current business practices. See "Business -- Customers" and "Business -- Sales
and Marketing."

DEPENDENCE ON SINGLE OR LIMITED SOURCE ASSEMBLY SUBCONTRACTORS

The Company primarily relies on foreign subcontractors for the assembly and
packaging of its products and, to a lesser extent, for the testing of its
finished products. Some of these subcontractors are the Company's single source
supplier for certain new packages. Although the Company believes that it is not
materially dependent upon any such subcontractor, changes in the Company's or a
subcontractor's business could cause the Company to become materially dependent
on a subcontractor. The Company has from time to time experienced difficulties
in the timeliness and quality of product deliveries from the Company's
subcontractors. Although delays experienced to date have not been material,
there can be no assurance that the Company will not experience similar or more
severe difficulties in the future. The Company generally purchases these single
or limited source components or services pursuant to purchase orders and has no
guaranteed arrangements with such subcontractors. There can be no assurance that
these subcontractors will continue to be able and willing to meet the Company's
requirements for any such components or services. Any significant disruption in
supplies from, or degradation in the quality of components or services supplied
by, these subcontractors, or any other circumstance that would require the
Company to qualify alternative sources of supply could delay shipments and
result in the loss of customers, or limitations or reductions in the Company's
revenues, or otherwise materially and adversely affect the Company's business,
financial condition and results of operations. Each of the Company's assembly
subcontractors is located outside the United States, which exposes the Company
to risks associated with international business operations, including foreign
governmental regulations, currency fluctuations, reduced protection for
intellectual property, changes in political conditions, disruptions or delays in
shipments and changes in economic conditions in the countries where these
subcontractors are located, any of which could have a material adverse effect on
the Company's business, financial condition and results of operations. In
particular, there is a potential risk of conflict and further instability in the
relationship between Taiwan and the People's Replublic of China, which could
cause a disruption in the operations of several of the Company's assembly
subcontractors located in Taiwan. See "Business -- Manufacturing."

16


ITEM 2. PROPERTIES

The Company leases approximately 47,500 square feet of space in San Jose,
California in which its headquarters, technology and product development and
testing facilities are located. The facility is leased through July 2004, with
certain renewal options. The Company also has sales offices located in San Jose,
California, Dallas, Texas, Marlborough, Massachusetts and Cary, North Carolina
as well as in Taiwan, Japan and the United Kingdom. The Company believes its
current facilities are adequate to support its needs through the end of fiscal
2000.


ITEM 3. LEGAL PROCEEDINGS

The semiconductor industry is characterized by frequent litigation regarding
patent and other intellectual property rights, and there can be no assurance
that the Company will not be subject to infringement claims by other parties. In
May 1995, Quality Semiconductor, Inc. ("QSI"), a competitor of the Company,
brought a lawsuit against the Company, claiming infringement of one of its
patents by certain features in certain of the Company's bus switch products and
seeking injunctive relief and unspecified monetary damages. The Company settled
this claim in fiscal 1999 without material adverse effect on the Company's
financial position or results of operations. However, any litigation, whether or
not determined in favor of the Company, can result in significant expense to the
Company and can divert the efforts of the Company's technical and management
personnel from productive tasks. In the event of an adverse ruling in any
litigation involving intellectual property, the Company might be required to
discontinue the use of certain processes, cease the manufacture, use and sale of
infringing products, expend significant resources to develop non-infringing
technology or obtain licenses to the infringed technology, and may suffer
significant monetary damages, which could include treble damages. In the event
the Company attempts to license any allegedly infringed technology, there can be
no assurance that such a license would be available on reasonable terms or at
all. In the event of a successful claim against the Company and the Company's
failure to develop or license a substitute technology on commercially reasonable
terms, the Company's business and results of operations would be materially and
adversely affected. There can be no assurance that any potential infringement
claims by other parties (or claims for indemnity from customers resulting from
any infringement claims) will not materially and adversely affect the Company's
business, financial condition and results of operations.
