PART I

ITEM 1. BUSINESS

GENERAL

Adaptec is a leading supplier of bandwidth management solutions that
significantly enhance total system performance by increasing the data transfer
rates between personal computers ("PCs"), servers, peripherals, and networks.
The Company's products include host adapters, which are primarily based on the
small computer system interface ("SCSI") standard, network products, CD
recordable software solutions, peripheral technology solutions, consisting
primarily of application specific integrated circuit ("ASIC") controllers for
hard disk and CD-ROM drives, and storage system solutions that incorporate RAID
and Fibre Channel technologies.

Adaptec provides its customers with complete solutions, consisting of hardware,
software, and firmware, which are incorporated into the products of
substantially all of the major Intel-based PC and server manufacturers
worldwide. Many of these solutions are based on the SCSI standard which has
become an important industry standard I/O bus specification for high-performance
systems. SCSI allows the "intelligent" transfer of data between computers,
peripherals, and networks by enabling multitasking and by offloading the system
CPU from I/O management.

The increase in the usage of data has created the need for solutions involving
increasing amounts of data storage as well as new high-capacity peripheral
devices. Virtually every microcomputer is shipped with mass storage peripherals
such as hard disk drives and CD-ROMs. Each peripheral requires an ASIC
controller to manage the operations of that peripheral and to interface with the
system bus. Recently, new peripherals, such as CD-ROMs and removable storage
devices, have been increasingly used alongside hard disks to provide additional
storage capacity. In addition, the increasing need for mass storage is also
driving the need for controller solutions that can support multi-gigabyte drives
in both desktop and server systems.

Adaptec also supports emerging high-performance solutions, such as Fibre Channel
and microprocessor based RAID. Fibre Channel is a bus technology targeted for
applications with very high-capacity I/O demands over long distances, which
offers unique capabilities in the clustering and very high end multi-processor
server environments. Fibre Channel has fostered the idea of a "storage area
network" where a Fibre Channel network exists independently of a local area
network (LAN). The storage area network moves data between storage devices and
servers while the LAN moves data between clients and servers. RAID is an acronym
for Redundant Array of Inexpensive (or Independent) Disks. A microprocessor RAID
array is a collection of drives which collectively act as a single storage
system, which can tolerate the failure of a drive without losing data and which
can operate independently of each other. RAID offloads overhead from the main
CPU allowing for enhanced system performance.

PRODUCTS

The Company's products are designed and manufactured using a core set of
technologies and resources. The Company's semiconductor technology design
centers develop products for all markets the Company serves. The Company
continues to utilize a process called concurrent engineering, in which
manufacturing, marketing, and engineering work together early in the development
cycle to meet the demands of emerging technologies as well as decrease the "time
to volume" of product shipments. The Company maintains an Internet Web site to
provide its customers with detailed company and product information.

Host Interface Solutions

The Company's host interface solutions, which include SCSI host adapters and
related firmware and software, meet the demanding I/O and connectivity
requirements of enterprise servers, high-performance desktop and portable
computers, and technical workstations across all important microprocessor-based
platforms.

The Company's host interface products, which incorporate the Company's
proprietary single chip architectures and related software products including CD
recordable solutions, provide customers comprehensive I/O solutions in the
markets it serves. Ultra2SCSI products include PCI Ultra2 solutions for
workstation applications such as CAD/CAM, financial analysis and desktop
publishing. Internal RAID solutions include RAID option cards for motherboards
equipped with a RAIDport II slot and PCI-to-Ultra SCSI Array Adapters. The
Company provides bus mastering, SCSI host adapters that manage all I/O
processing activity, thereby freeing the CPU to perform other operations. The
Company offers these host adapters across all ranges of bus architectures
including PCI, Fibre Channel, ISA, EISA, and PCMCIA as well as for previous
generations of the SCSI standard. The Company also provides non-bus mastering
host adapters that provide standardized SCSI connectivity between the CPU and
its peripherals. To expand further the market for its products, the Company
continues to develop and market I/O solutions meeting specific original
equipment manufacturer ("OEM") requirements and turnkey kits for the distributor
channels. These kits include a SCSI host adapter and related software that
enable end-users to more readily connect SCSI peripherals to their
microcomputer.

The Company has undertaken numerous initiatives to increase the accessibility,
ease of use, and versatility of the SCSI standard. Advanced SCSI programming
interface ("ASPI"), an industry standard developed by the Company, enables users
to integrate high-performance SCSI peripherals with microcomputers using popular
operating systems, such as Windows 95, Windows NT, NetWare, OS/2, and UNIX. In
addition, the Company is engaged in strategic relationships with leading
operating system vendors, such as IBM, Microsoft, and Novell, resulting in joint
development projects to embed the Company's software within their operating
systems. The Company has several software utilities such as Adaptec EZ-SCSI and
SCSIselect products, which simplify connecting a SCSI host adapter and
peripherals to a microcomputer system. The Company also provides networking
products such as Fast Ethernet adapters and Duralink software.

Semiconductor Solutions

The Company develops proprietary integrated circuits ("ICs") for use in
microcomputer systems, mass storage devices, various other peripherals, and for
use in its own board-based SCSI host adapters and NICs. Adaptec's proprietary
ICs provide innovative solutions for managing complex I/O functions in
high-performance microcomputer and storage applications. Working closely with
customers, the Company provides complete solutions that include sophisticated
ICs, firmware, and software that optimize overall subsystem design.

The Company's semiconductor solutions include SCSI and enhanced integrated
device electronic ("EIDE") programmable storage controllers and single-chip SCSI
host adapters. All of the Company's IC products are developed using advanced
design technologies to meet market requirements for higher levels of physical
integration, increased functionality, and performance. The Company's
programmable SCSI and EIDE storage controllers are typically configured to
address specific customer requirements in the mass storage market and are used
primarily in high-capacity hard disk drives. The Company's SCSI host adapter ICs
incorporate similar technology and are used by system manufacturers to embed
SCSI on the system motherboard.

Storage System Solutions

The Company's storage system solutions include RAID for external storage,
primarily in the NT server market, and Fibre Channel solutions. RAID for
external storage includes external RAID controller boards and external RAID
"canisters". External RAID controller boards are sold to OEMs for integration
into their external storage subsystems. Canisters are sold primarily to VARs and
resellers through the distribution channel for integration into RAID storage
subsystems.

The Company's Fibre Channel products include PCI-to-Fibre Channel host adapters
which bring Fibre Channel peripheral attachment and clustering interconnection
to 32-bit/64-bit PCI workstations and servers. These PCI-to-Fibre Channel host
adapters are compatible with a wide range of hardware platforms, operating
systems and peripherals and are sold directly to OEMs and through distribution
with kitted solutions.

RESEARCH AND DEVELOPMENT

The Company believes research and development is fundamental to its success,
especially in integrated circuit design, software development, and I/O solutions
that encompass emerging technologies. The development of proprietary integrated
circuits that support multiple architectures and peripheral devices requires a
combination of engineering disciplines. In addition, extensive knowledge of
computer and subsystem architectures, expertise in the design of high-speed
digital ICs circuits, and knowledge of operating system software is essential.
The Company's research and development efforts continue to focus on the
development of complete solutions that include proprietary ASICs, firmware, and
software that support multiple architectures and peripheral devices. These I/O
solutions facilitate high-speed data transfer rates, which are essential to the
enhanced performance of client/server networking environments, applications
requiring high-performance I/O, and the adoption of various peripheral devices.

The Company intends to continue to leverage its technical expertise and product
innovation capabilities to address I/O solutions across a broad range of users
and platforms. The Company has invested significant resources to develop its
core products as well as newer hardware and software solutions including CD-R,
Fibre Channel, File Array, RAID and external storage. The Company is currently
evaluating the stage of development and market potential of various of these
technologies and, as a result of its recent financial performance, may decide to
curtail or terminate its development efforts in certain areas.

Approximately 28% of the Company's employees are engaged in research and
development, of whom approximately 50% are engaged in software development. In
fiscal 1998, 1997, and 1996, the Company spent approximately $173 million (17%
of net revenues), $129 million (14% of net revenues) and $88 million (13% of net
revenues), respectively, for research and development.

MARKETING AND CUSTOMERS

The Company believes it has successfully positioned itself as a leading supplier
of a full range of I/O solutions providing bandwidth management. The Company
sells its products through a direct sales force to substantially all major
server and PC manufacturers, as well as most of the major electronic
distributors worldwide. The Company works closely with its OEM customers on the
design of current and next generation products to meet the specific requirements
of system integrators and end-users. The Company provides its OEM customers with
extensive applications and system design support. The Company also sells
board-based products to end-users through major computer product distributors
and provides technical support to its customers worldwide.

The Company's OEM customers include Acer, Compaq Computer, DEC, Dell Computer
Corporation, Fujitsu, Gateway 2000, Hewlett-Packard Company, IBM Corporation,
Intel Corporation, Samsung, Siemens Nixdorf, Silicon Graphics, Toshiba America,
and Western Digital. The Company's major distributors include Actebis, CHS
Electronics, Computer 2000, Gates/Arrow, Globelle, Ingram Micro, Metrologie,
Merisel, Nissho, and Tech Data. In fiscal 1998 and 1997, no customer accounted
for more than 10% of the Company's net revenues. In fiscal 1996, sales to one
distributor represented 10% of the Company's net revenues.

The Company emphasizes solution-oriented customer support as a key element of
its marketing strategy and maintains technical applications groups in the field
as well as at the Company's headquarters. Support provided by these groups
includes assisting current and prospective customers in the use of the Company's
products, writing application notes, and conducting seminars for system
designers. The systems-level expertise and software experience of the Company's
engineering staff are also available to customers with particularly difficult
I/O design problems. A high level of customer support is also maintained through
technical support hotlines, electronic bulletin boards, and dial-in-fax
capability.

International net revenues accounted for approximately 60%, 61%, and 56% of net
revenues in fiscal 1998, 1997, and 1996, respectively. Sales of the Company's
products internationally are subject to certain risks common to all export
activities, such as governmental regulation and the risk of imposition of
tariffs or other trade barriers. Sales to customers are denominated in U.S.
dollars.

COMPETITION

In the host adapter market, the Company competes with a number of host adapter
manufacturers. The Company's competitive strategy is to continue to leverage its
technical leadership and concentrate on the most technology-intensive solutions.
To address the competitive nature of the business the Company designs advanced
features into its products, with particular emphasis on data transfer rates,
software-defined features, and compatibility with major operating systems and
most peripherals. The Company believes the principal competitive factors in this
market are performance, a comprehensive array of solutions ranging from
connectivity products for the personal computing market to high-performance
products for the enterprise-wide computing and networked environments, product
features, brand awareness, financial resources, and technical and administrative
support. The Company believes that it presently competes favorably with respect
to each of these factors.

As the Company enters the market for storage systems solutions, it expects to
experience significant competition from both existing competitors and additional
companies that may enter this market. Some of these companies have greater
technical, marketing, manufacturing, and financial resources than the Company.

The Company's principal competitors for semiconductor solutions in the mass
storage market are captive suppliers, Texas Instruments and Cirrus Logic, Inc.
The Company believes that its competitive strengths in the mass storage market
include its systems level expertise, integrated circuit design capability, and
substantial experience in I/O applications. The Company believes the principal
competitive factors in achieving design wins are performance, product features,
price, quality, and technical and administrative support. The Company believes
that it presently competes favorably with respect to each of these factors.

The markets for the Company's products are highly competitive and are
characterized by rapid technological advances, frequent new product
introductions, evolving industry standards, and competitive price pressures. The
Company's competitors continue to introduce products with improved performance
characteristics, and its customers continue to develop new applications. As the
Company has continued to broaden its bandwidth management product offerings into
the desktop and server environments, it has experienced, and expects to
experience in the future, significantly increased competition both from existing
competitors and from additional companies that may enter its markets. Some of
these companies have greater technical, marketing, manufacturing, and financial
resources than the Company. The Company will have to continue to develop and
market appropriate products to remain competitive. The Company believes one of
the factors in its competitive success is its continued commitment of resources
to research and development.

BACKLOG

At March 31, 1998, the Company's backlog was approximately $61 million compared
with $154 million at March 31, 1997. The Company believes that the trend to
lower priced PCs for mainstream corporate desktop applications, the turbulent
disk drive market and the recent instability in the Asian markets are, among
other things, factors which may have contributed to the decrease in the backlog.
However, backlog levels may also vary with product availability, delivery lead
times and customer order delays, changes or cancellations. Accordingly, the
Company's backlog as of any particular date may not necessarily be a reliable
indicator of future operating results.

MANUFACTURING

The Company's Singapore manufacturing facility produces and tests high volume
host adapter products. The Singapore facility has earned ISO 9001 certification,
a stringent quality standard that has become a requirement for doing business
globally. Since establishing this facility in Singapore in 1988, the Company has
experienced lower costs, shorter manufacturing cycle times, and improved service
to customers. The Company's products make extensive use of standard logic,
printed circuit boards, and random access memory from several outside suppliers
in addition to the Company's custom designed integrated circuits. Additionally,
during fiscal 1998, to ensure availability of low cost manufacturing capacity
for certain product lines, the Company's Singapore plant continued to develop
relationships with major local subcontracting manufacturers by consigning
certain production equipment to the subcontractors.

All semiconductor wafers used in manufacturing the Company's products are
processed to its specifications by outside suppliers and internally tested by
the Company. The Company has secured capacity through agreements with Taiwan
Semiconductor Manufacturing Co., Ltd. ("TSMC") that ensure availability of a
portion of the Company's wafer capacity for both current and future technologies
for which the Company has made advance payments. The Company also purchases
wafers from SGS-Thompson Microelectronics and Seiko Epson.

PATENTS AND LICENSES

The Company believes that patents are of less significance in its industry than
such factors as innovative skills, technological expertise, and marketing
abilities. However, the Company encourages its engineers to document patentable
inventions and has applied for and continues to apply for patents both in the
United States and in foreign countries when it deems it to be advantageous to do
so. There can be no assurance that patents will be issued or that any patent
issued will provide significant protection or could be successfully defended.

As is the case with many companies in the electronics industry, it may be
desirable in the future for the Company to obtain technology licenses from other
companies. The Company has occasionally received notices of claimed infringement
of intellectual property rights and may receive additional such claims in the
future. The Company evaluates all such claims and, if necessary, will seek to
obtain appropriate licenses. There can be no assurance that any such licenses,
if required, will be available on acceptable terms.

EMPLOYEES

At March 31, 1998, the Company had 3,276 employees. The Company's continued
success will depend in large measure on its ability to attract and retain highly
skilled employees who are in great demand.

FOREIGN AND DOMESTIC OPERATIONS

Incorporated by reference from information under the caption " Note 10. Segment
Information" in the Notes to Consolidated Financial Statements on pages B21 and
B22 of the Annual Report to Stockholders for the fiscal year ended March 31,
1998.

CERTAIN FACTORS BEARING ON FUTURE RESULTS

This report contains forward-looking statements that involve risks and
uncertainties. For example, Management's Discussion and Analysis of Results of
Operations and Financial Condition which is incorporated by reference from the
Company's Annual Report includes statements relating to expected sales growth,
anticipated operating expenditures and anticipated capital expenditures. The
statements contained in this document that are not purely historical are
forward-looking statements within the meaning of Section 27A of the Securities
Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including
without limitation statements regarding the Company's expectations, beliefs,
intentions or strategies regarding the future. All forward-looking statements
included in this document are based on information available to the Company on
the date hereof, and the Company assumes no obligation to update any such
forward-looking statements. The Company's actual results could differ materially
from those anticipated in these forward-looking statements as a result of
certain factors, including those set forth in the following risk factors and
elsewhere in this document. In evaluating the Company's business, prospective
investors should consider carefully the following factors in addition to the
other information set forth in this document.

Future Operating Results Subject to Fluctuation. In the second half of fiscal
1998, the Company's operating results were adversely affected by shifts in
corporate and retail buying patterns, increased competition, economic
instability in Asia and turbulence in the computer disk drive industry. In the
future, the Company's operating results may fluctuate as a result of these
factors and as a result of a wide variety of other factors, including, but not
limited to, cancellations or postponements of orders, shifts in the mix of the
Company's products and sales channels, changes in pricing policies by the
Company's suppliers, interruption in the supply of custom integrated circuits,
the market acceptance of new and enhanced versions of the Company's products,
product obsolescence and general worldwide economic and computer industry
fluctuations. In addition, fluctuations may be caused by future accounting
pronouncements, changes in accounting policies, and the timing of acquisitions
of other business products and technologies and any associated charges to
earnings. The volume and timing of orders received during a quarter are
difficult to forecast. The Company's customers from time to time encounter
uncertain and changing demand for their products. Customers generally order
based on their forecasts. If demand falls below such forecasts


9


11

or if customers do not control inventories effectively, they may cancel or
reschedule shipments previously ordered from the Company. The Company has
historically operated with a relatively small backlog, especially relating to
orders of its host interface solutions and has set its operating budget based in
part on expectations of future revenues. Because much of the Company's operating
budget is relatively fixed in the short term, if revenues do not meet the
Company's expectations, as happened in the fourth quarter of fiscal 1998, then
the Company's operating income and net income may be disproportionately
affected. Operating results in any particular quarter which do not meet the
expectations of securities analysts are likely to cause volatility in the price
of the Company's Common Stock.

Certain Risks Associated with the High-Performance Microcomputer Market. The
Company's host interface solutions are used primarily in high performance
computer systems designed to support bandwidth-intensive applications and
operating systems. Historically, the Company's growth has been supported by
increasing demand for systems that support client/server and Internet/intranet
applications, computer-aided engineering, desktop publishing, multimedia, and
video. During the second half of fiscal 1998, the demand for such systems slowed
as more businesses chose to use relatively inexpensive PC's for desktop
applications and information technology managers shifted resources toward
resolving Year 2000 problems and investing in network infrastructure. Should
demand for such systems continue to slow, the Company's business or operating
results could be materially adversely affected by a resulting decline in demand
for the Company's products.

Certain Risks Associated with the Computer Peripherals Market. As a supplier of
controller circuits to manufacturers of computer peripherals such as disk drives
and other storage devices, a portion of the Company's business is dependent on
the overall market for computer peripherals. This market, which itself is
dependent on the market for personal computers, has historically been
characterized by periods of rapid growth followed by periods of oversupply and
contraction. As a result, suppliers to the computer peripherals industry from
time to time experience large and sudden fluctuations in demand for their
products as their customers adjust to changing conditions in their markets. If
these fluctuations are not accurately anticipated, as happened in the second
half of fiscal 1998, such suppliers, including the Company, could produce
excessive or insufficient inventories of various components which could
materially and adversely affect the Company's business and operating results.
The computer peripherals industry is also characterized by intense
price-competition, which in turn creates pricing pressures on the suppliers to
that industry. If the Company is unable to correspondingly decrease its
manufacturing or component costs, such pricing pressures could have a material
adverse effect on the Company's business or operating results.

Reliance on Industry Standards, Technological Change, Dependence on New
Products. The computer industry is characterized by various standards and
protocols that evolve with time. The Company's current products are designed to
conform to certain industry standards and protocols such as SCSI, UltraSCSI,
Ultra2 SCSI, PCI, RAID, Fibre Channel, ATM, and Fast Ethernet. In particular, a
majority of the Company's revenues are currently derived from products based on
the SCSI standard. If consumer acceptance of these standards was to decline, or
if they were replaced with new standards, and if the Company did not anticipate
these changes and develop new products, the Company's business or operating
results could be materially adversely affected. For example, the Company
believes that changes in consumers' perceptions of the relative merits of SCSI
based products and products incorporating a competing standard, Ultra-DMA, have
recently started to adversely affect the sales of the Company's products and may
adversely affect the Company's future sales.



10

12

The markets for the Company's products are characterized by rapidly changing
technology, frequent new product introductions, and declining average selling
prices over product life cycles. The Company's future success is therefore
highly dependent upon the timely completion and introduction of new products at
competitive price/performance levels. The success of new product introductions
is dependent on several factors, including proper new product definition,
product costs, timely completion and introduction of new product designs,
quality of new products, differentiation of new products from those of the
Company's competitors, and market acceptance of the Company's and its customers'
products. As a result, the Company believes that continued significant
expenditures for research and development will be required in the future. There
can be no assurance that the Company will successfully identify new product
opportunities and develop and bring new products to market in a timely manner,
that products or technologies developed by others will not render the Company's
products or technologies obsolete or noncompetitive, or that the Company's
products will be selected for design into the products of its targeted
customers. The failure of any of the Company's new product development efforts
could have a material adverse effect on the Company's business or operating
results. In addition, the Company's revenues and operating results could be
adversely impacted if its customers shifted their demand to a significant extent
away from board-based I/O solutions to application-specific ICs.

Dependence on Wafer Suppliers and Other Subcontractors. All of the finished
silicon wafers used for the Company's products are currently manufactured to the
Company's specifications by independent foundries. The Company currently
purchases a substantial majority of its wafers through a supply agreement with
TSMC. The Company also purchases wafers from SGS-Thomson Microelectronics and
Seiko Epson. The manufacture of semiconductor devices is sensitive to a wide
variety of factors, including the availability of raw materials, the level of
contaminants in the manufacturing environment, impurities in the materials used,
and the performance of personnel and equipment. While the quality, yield, and
timeliness of wafer deliveries to date have been acceptable, there can be no
assurance that manufacturing yield problems will not occur in the future. In
addition, although the Company has various supply agreements with its suppliers,
a shortage of raw materials or production capacity could lead any of the
Company's wafer suppliers to allocate available capacity to customers other than
the Company, or to internal uses. Any prolonged inability to obtain wafers with
competitive performance and cost attributes, adequate yields, or timely
deliveries from its foundries would delay production and product shipments and
could have a material adverse effect on the Company's business or operating
results. The Company expects that it will in the future seek to convert its
fabrication process arrangements to smaller geometries and to more advanced
process technologies. Such conversions entail inherent technological risks that
can affect yields and delivery times. If for any reason the Company's current
suppliers were unable or unwilling to satisfy the Company's wafer needs, the
Company would be required to identify and qualify additional foundries. There
can be no assurance that any additional wafer foundries would become available,
that such foundries would be successfully qualified, or that such foundries
would be able to satisfy the Company's requirements on a timely basis.

The Company's future growth will depend in large part on increasing its wafer
capacity allocation from current foundries, adding additional foundries, and
gaining access to advanced process technologies. There can be no assurance that
the Company will be able to satisfy its future wafer needs from current or
alternative sources. Any increase in general demand for wafers within the
industry or any reduction of existing wafer supply from any of the Company's
foundry sources, could materially adversely affect the Company's business,
financial condition, or operating results.

In order to secure wafer capacity, the Company from time to time has entered
into "take or pay" contracts that committed the Company to purchase specified
wafer quantities over extended periods, and has made

11


13

prepayments to foundries. In the future, the Company may enter into similar
transactions or other transactions, including, without limitation,
non-refundable deposits with or loans to foundries, or equity investments in,
joint ventures with or other partnership relationships with foundries. Any such
transaction could require the Company to seek additional equity or debt
financing to fund such activities. There can be no assurance that the Company
will be able to obtain any required financing on terms acceptable to the
Company.

Additionally, the Company relies on subcontractors for the assembly and
packaging of the ICs included in its products. The Company has no long-term
agreements with its assembly and packaging subcontractors. In addition, the
Company is increasingly using board subcontractors to better balance production
runs and capacity. There can be no assurance that such subcontractors will
continue to be able and willing to meet the Company's requirements for such
components or services. Any significant disruption in supplies from, or
degradation in the quality of components or services supplied by, such
subcontractors could delay shipments and result in the loss of customers or
revenues or otherwise have a material adverse effect on the Company's business
or operating results.

Certain Risks Associated With Acquisitions. Since the beginning of fiscal 1996,
the Company has completed the acquisition of 13 complementary companies and
businesses. As part of its overall strategy, the Company plans to continue to
acquire or invest in complementary companies, products, or technologies and to
enter into joint ventures and strategic alliances with other companies. Risks
commonly encountered in such transactions include the difficulty of assimilating
the operations and personnel of the combined companies, the potential disruption
of the Company's ongoing business, the inability to retain key technical and
managerial personnel, the inability of management to maximize the financial and
strategic position of the Company through the successful integration of acquired
businesses, additional expenses associated with amortization of acquired
intangible assets, dilution of existing equity holders, the maintenance of
uniform standards, controls, procedures, and policies, and the impairment of
relationships with employees and customers as a result of any integration of new
personnel. There can be no assurance that the Company will be successful in
overcoming these risks or any other problems encountered in connection with such
business combinations, investments, or joint ventures, or that such transactions
will not materially adversely affect the Company's business, financial
condition, or operating results.

Certain Risks Associated with Implementation and Utilization of New Information
Systems. The Company has recently implemented new information systems in its
operations in the United States, Singapore and Europe and will implement new
information systems in its operations in Japan. There can be no assurance that
the Company will successfully implement and utilize these new systems
efficiently and in a timely manner. Problems with installation or utilization of
the new systems could cause substantial difficulties in operations, financial
reporting and management and thus could have a material adverse effect on the
Company's business or operating results.

Year 2000 Issues. The "Year 2000 issue" arises because most computer systems and
programs were designed to handle only a two-digit year not a four-digit year.
When the Year 2000 begins, these computers may interpret "00" as the year 1900
and could either stop processing date-related computations or could

12


14

process them incorrectly. The Company has recently implemented new information
systems and accordingly does not anticipate any internal Year 2000 issues from
its own information systems, databases or programs. However, the Company could
be adversely impacted by Year 2000 issues faced by major distributors,
suppliers, customers, vendors and financial service organizations with which the
Company interacts. The Company has sent surveys to certain third parties to
determine whether they are Year 2000 compliant and is in the process of
evaluating and following up on responses to determine the impact that third
parties who are not Year 2000 compliant may have on the operations of the
Company. The Company believes it is currently being impacted by the redirection
of corporate management information system budgets towards resolving the Year
2000 issue. Continuation of this trend could lower the demand for the Company's
products if corporate buyers defer purchases of high-end business PCs.

Competition. The markets for the Company's products are intensely competitive
and are characterized by rapid technological advances, frequent new product
introductions, evolving industry standards, and price erosion. In the host
adapter market, the Company competes with a number of host adapter
manufacturers. The Company's principal competitors for semiconductor solutions
in the mass storage market are captive suppliers and Cirrus Logic, Inc. As the
Company has continued to broaden its bandwidth management product offerings into
the desktop, server, and networking environments, it has experienced, and
expects to experience in the future, significantly increased competition both
from existing competitors and from additional companies that may enter its
markets. Some of these companies have greater technical, marketing,
manufacturing, and financial resources than the Company. There can be no
assurance that the Company will be able to make timely introduction of new
leading-edge solutions in response to competitive threats, that the Company will
be able to compete successfully in the future against existing or potential
competitors or that the Company's business or operating results will not be
materially adversely affected by price competition.

Certain Issues Related to Distributors. The Company's distributors generally
offer a diverse array of products from several different manufacturers.
Accordingly, there is a risk that these distributors may give higher priority to
selling products from other suppliers, thus reducing their efforts to sell the
Company's products. A reduction in sales efforts by the Company's current
distributors could have a materially adverse effect on its business or operating
results. The Company's distributors may on occasion build inventories in
anticipation of substantial growth in sales, and if such growth does not occur
as rapidly as anticipated, distributors may decrease the amount of product
ordered from the Company in subsequent quarters. In addition, there has recently
been an industry trend towards the elimination of price protection and
distributor incentive programs. This trend could result in a change in
distributor business habits, with distributors possibly deciding to decrease the
amount of product held so as to reduce inventory levels and this in turn could
reduce the Company's revenues in any given quarter and give rise to fluctuation
in the Company's operating results.

Dependence on Key Personnel. The Company's future success depends in large part
on the continued service of its key technical, marketing, and management
personnel, and on its ability to continue to attract and retain qualified
employees, particularly those highly skilled design, process, and test engineers
involved in the design enhancements and manufacture of existing products and the
development of new products and processes. The competition for such personnel is
intense, and the loss of key employees could have a material adverse effect on
the Company's business or operating results. The Company believes the recent
weakness in its financial performance and the resulting decline in its stock
price has adversely impacted its ability to attract and retain qualified
employees.

13
15

Certain Risks Associated with International Operations. The Company's
manufacturing facility and various subcontractors it utilizes from time to time
are located primarily in Asia. Additionally, the Company has various sales
offices and customers throughout Europe, Japan, and other countries. The
Company's international operations and sales are subject to political and
economic risks, including political instability, currency controls, exchange
rate fluctuations, and changes in import/export regulations, tariffs, and
freight rates. The Company may use forward exchange contracts to manage any
exposure associated with certain foreign currency denominated commitments. In
addition, because the Company's principal wafer supplier, TSMC, is located in
Taiwan, the Company is subject to the risk of political instability in Taiwan,
including the potential for conflict between Taiwan and the People's Republic of
China.

Intellectual Property Protection and Disputes. The Company has historically
devoted significant resources to research and development and believes that the
intellectual property derived from such research and development is a valuable
asset that has been and will continue to be important to the success of the
Company's business. Although the Company actively maintains and defends its
intellectual property rights, no assurance can be given that the steps taken by
the Company will be adequate to protect its proprietary rights. In addition, the
laws of certain territories in which the Company's products are or may be
developed, manufactured, or sold, including Asia and Europe, may not protect the
Company's products and intellectual property rights to the same extent as the
laws of the United States. The Company has from time to time discovered
counterfeit copies of its products being manufactured or sold by others.
Although the Company maintains an active program to detect and deter the
counterfeiting of its products, should counterfeit products become available in
the market to any significant degree it could materially adversely affect the
business or operating results of the Company.

From time to time, third parties may assert exclusive patent, copyright, and
other intellectual property rights to technologies that are important to the
Company. There can be no assurance that third parties will not assert
infringement claims against the Company in the future, that assertions by third
parties will not result in costly litigation or that the Company would prevail
in such litigation or be able to license any valid and infringed patents from
third parties on commercially reasonable terms. Litigation, regardless of its
outcome, could result in substantial cost and diversion of resources of the
Company. Any infringement claim or other litigation against or by the Company
could materially adversely affect the Company's business or operating results.

Need for Interoperability. The Company's products must be designed to
interoperate effectively with a variety of hardware and software products
supplied by other manufacturers, including microprocessors, peripherals, and
operating system software. The Company depends on significant cooperation with
these manufacturers in order to achieve its design objectives and produce
products that interoperate successfully. While the Company believes that it
generally has good relationships with leading system, peripheral, and
microprocessor suppliers, there can be no assurance that such suppliers will not
from time to time make it more difficult for the Company to design its products
for successful interoperability or decide to compete with the Company.

Natural Disasters. The Company's corporate headquarters are located near major
earthquake faults. Any damage to the Company's information systems caused as a
result of an earthquake, fire, La Nina related floods or any other natural
disasters could have a material adverse effect on the Company's business,
results of operations and financial condition.

Volatility of Stock Price. The stock market in general, and the market for
shares of technology companies in particular, have from time to time experienced
extreme price fluctuations, which have often been unrelated

14


16

to the operating performance of the affected companies. In addition, factors
such as technological innovations or new product introductions by the Company,
its competitors, or its customers may have a significant impact on the market
price of the Company's Common Stock. Furthermore, as occurred in the fourth
quarter of fiscal 1998, quarter-to-quarter fluctuations in the Company's results
of operations caused by changes in customer demand, changes in the microcomputer
and peripherals markets, or other factors, may have a significant impact on the
market price of the Company's Common Stock. In addition, the Company's stock
price may be affected by general market conditions and international
macroeconomic factors unrelated to the Company's performance such as those
recently evidenced by the financial turmoil in Asia. These conditions, as well
as factors that generally affect the market for stocks of high technology
companies, could cause the price of the Company's Common Stock to fluctuate
substantially over short periods.

ITEM 2. PROPERTIES

The Company owns seven buildings (approximately 439,000 square feet) in
Milpitas, California, which are primarily used by the Company for corporate
offices, research, manufacturing, marketing, and sales, and one building
(approximately 200,000 square feet) in Longmont, Colorado, for research,
technical support, marketing, sales, and administrative support. The Company
leases three buildings (approximately 81,000 square feet) in Milpitas,
California, which are mainly occupied to support administrative and sales
functions, and other facilities in Irvine, California (82,000 square feet);
Bellevue, Washington (9,000 square feet); Hudson, Wisconsin (6,000 square feet);
and Nashua, New Hampshire (23,000 square feet) to support technical design
efforts and sales.

Adaptec Manufacturing Singapore is located in two leased facilities
(approximately 126,000 square feet). The two buildings are used by the Company
for research, manufacturing, and sales. The Company also leases six sales
offices in the United States, and one sales office each in Waterloo, Belgium;
Munich, Germany; Bretonneux, France; Camberley, England; Singapore; Seoul,
Korea; Taipei, Taiwan; and Tokyo, Japan. The Tokyo office also provides
technical design efforts and technical support with the Brussels office
providing technical support to Europe. The Company believes its existing
facilities and equipment are well maintained and in good operating condition and
believes its manufacturing facilities, together with the use of independent
manufacturers where required or desirable, will be sufficient to meet its
anticipated manufacturing needs through fiscal 1999.

During fiscal 1998 and fiscal 1996, the Company acquired parcels of land in
Fremont and Irvine, California, for approximately $12 million and $11 million
respectively. The Company's future facilities requirements will depend upon the
Company's business, and the Company believes additional space, if required, may
be obtained on reasonable terms.
