ITEM 1.  BUSINESS.
 
GENERAL
 
     Adaptec is a leading supplier of input/output (I/O) hardware and software
(referred to by the Company as IOware solutions) used to eliminate performance
bottlenecks between a microcomputer's central processing unit (CPU) and its
peripheral devices, such as hard disk, optical and tape storage devices, and
network file servers. The Company's IOware products include board-based I/O
solutions using extensive proprietary software and proprietary very large scale
integration (VLSI) integrated circuits (ICs). The Company's host adapter
products are based on the Small Computer Systems Interface (SCSI) standard,
which interfaces with all standard microcomputer architectures. The Company's IC
products include single chip disk controllers for SCSI, AT and PCMCIA hard disk
drives and single chip SCSI host adapters.
 
BACKGROUND
 
     The market for high-performance microcomputers and related products, which
are typically used in multiuser and multitasking environments, has continued to
grow more rapidly than the overall microcomputer market in recent years. A key
factor driving this growth has been the development of increasingly
sophisticated software for applications such as networking, transaction
processing, high resolution graphics and multimedia. These application
developments have resulted in the need for increased data transmission rates
between CPUs and peripherals to alleviate I/O bottlenecks which would limit the
overall performance of microcomputer systems. The Company addresses these needs
with products that significantly enhance and optimize overall microcomputer
system performance, particularly in complex operating environments, involving
sophisticated applications and multiple peripherals.
 
MARKET OVERVIEW
 
     The Company provides value-added IOware solutions to the personal
computing, enterprise computing and mass storage markets. The Company believes
that technical leadership, product innovation, marketing expertise and brand
name recognition allow it to compete favorably in these markets.
 
     Desktop and portable personal computers are used in a number of
environments including business, home and travel. Operating systems for
computing have historically been text-based and single-tasking such as MS-DOS.
During the past several years Graphical User Interfaces (GUIs) such as
Microsoft's Windows, have increasingly been shipped by Original Equipment
Manufacturers (OEMs) as standard in most desktop and portable computers.
Additionally, many desktop and portable personal computers are being configured
with a more diverse set of peripherals, such as CD-ROM, Tape, Write Once Read
Many (WORM), CD ROM Recordable (CDR) and Digital Audio Tape (DAT) drives, either
at the time of purchase or after the original equipment sale. When this occurs,
ease of installation and configuration are of great importance to the end user,
giving products that provide this capability a significant competitive
advantage.
 
     The enterprise computing market is characterized by increasingly more
sophisticated and I/O-intensive applications, such as network management
software, and distributed multimedia and business applications. During the past
several years, these applications have been migrating from minicomputers to
client/server environments. These applications typically require a file server
to be configured with multiple peripherals such as WORM, CD-ROM and DAT drives,
together with hard disk subsystems that provide security and data integrity
capabilities such as Redundant Array of Inexpensive Disks (RAID). Successful
implementation of such mission critical systems requires significant knowledge
of networking software and I/O subsystems.
 
     Virtually every microcomputer is shipped with inexpensive mass storage
devices which are required to store vast amounts of information and data. Such
devices include CD-ROM, tape drives and most commonly rigid or hard disk drives.
Non-hard disk devices are increasingly used in addition to a hard disk and often
have SCSI interfaces. Common uses for non-hard disk SCSI devices include data
backup and archiving for tape drives and storage needed for multimedia programs
where video, text, graphics and sound are stored on a
 
                                        2
<PAGE>   4
 
CD-ROM or CDR. Hard disk drives are usually part of a standard desktop, portable
or networked microcomputer configuration, and generally are used to store
operating systems, user applications and data files. Most hard disk drives are
shipped with either an AT or a SCSI interface and have relatively fast data
access and transfer capabilities. Cost per megabyte of storage and performance
characteristics such as average seek time, data transfer rate and spindle
rotational speed continue to be critical to success in the disk drive market.
 
PRODUCTS
 
     The Company's IOware products are designed and manufactured using a core
set of technologies and resources. The Company's semiconductor technology design
center develops products for all markets the Company serves. The Company
utilizes a process called concurrent engineering, in which manufacturing,
marketing and engineering work together early in the development cycle, to
decrease the "time to volume" of product shipments.
 
  Board-based I/O Solutions
 
     The Company's board-based I/O solutions are designed to support business,
technical and multimedia applications in the personal and enterprise computing
markets. The Company's single chip host adapters are the principal component of
these products. These ICs, together with the Company's extensive array of
software products, provide customers the most comprehensive board-based I/O
solutions available in the markets it serves. The Company provides bus
mastering, multitasking host adapters that manage all I/O processing activity,
thereby freeing the CPU to focus most of its power on task processing. The
Company also provides non-bus mastering host adapters which provide standardized
SCSI connectivity between the CPU and its peripherals. The Company's board-based
I/O solutions are capable of interfacing with most major microcomputer
architectures, including PCI, VESA, ISA, EISA and Micro Channel. Demand for the
Company's board-based I/O solutions has increased with the continued adoption of
SCSI as the high-performance I/O standard in personal computing. Additionally,
demand is being driven by the increased use of file servers where SCSI usage
approaches 100%. To meet this increased demand, the Company continues to develop
and market I/Oware solutions meeting specific OEM requirements and turnkey kits
for the distributor channels. These kits include a SCSI host adapter and related
software, that enable end-users to connect SCSI peripherals to their
microcomputer system.
 
     To facilitate the use of SCSI in microcomputer systems, the Company
developed Advanced SCSI Programming Interface (ASPI), an operating system-level
interface allowing seamless connectivity between SCSI host adapters and
operating systems. ASPI enables users to integrate high-performance SCSI
peripherals with microcomputers using popular operating systems, such as DOS,
NetWare, OS/2 and UNIX. Additionally, ASPI supports the current release of
Microsoft Windows operating environment; the Company has also been working with
Microsoft to ensure that ASPI will support Windows 95. 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. In addition, the Company has
developed several software utilities such as Adaptec EZ-SCSI and SCSISelect
products, which simplify connecting a SCSI host adapter and peripherals to a
microcomputer system.
 
  Integrated Circuits
 
     The Company develops proprietary integrated circuits for use in mass
storage devices and microcomputer systems and for use in its own board-based
SCSI host adapters. Adaptec's proprietary integrated circuits 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 integrated circuits, with related
firmware and software, to optimize overall subsystem design. In addition, the
Company seeks to establish its proprietary integrated circuits as industry
standards, thereby increasing market acceptance by new customers.
 
                                        3
<PAGE>   5
 
     The Company's current IC products include SCSI, PCMCIA and AT 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 AT 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 integrated circuits incorporate similar technology
and are used by system manufacturers to embed SCSI on the system motherboard and
by multifunction card companies to provide a SCSI interface.
 
RESEARCH AND DEVELOPMENT
 
     The Company believes research and development is fundamental to its
success, especially in integrated circuit design and software development. 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 integrated circuits
and knowledge of operating system software is essential. The integration of
these specialized disciplines has enabled the Company to address more
comprehensively the needs of the I/O microcomputer industry.
 
     The Company continues to leverage its technical expertise and product
innovation capabilities to address applications requiring the management and
high-speed transmission of microcomputer system data. Among the products under
development are higher performance host adapters for microcomputers using PCI
and ISA architectures, more highly integrated and functionally robust integrated
circuits and software support for additional operating systems. While SCSI
solutions currently remain the core of the Company's business, in fiscal 1995
the Company broadened its development efforts to include asynchronous transfer
mode (ATM), RAID, Serial I/O, and infrared technologies.
 
     Approximately 22% of the Company's employees are engaged in research and
development. In fiscal 1995, 1994 and 1993, the Company spent approximately
$60.8 million, $40.0 million, and $26.3 million respectively, for research and
development.
 
MARKETING AND CUSTOMERS
 
     The Company sells its products through both OEM and distributor channels
and packages these products to meet the specific requirements of system
integrators and end users. The Company works closely with its OEM customers on
the design of current and next generation products that incorporate the
Company's SCSI host adapters and integrated circuits. The Company provides its
OEM customers with extensive applications and system design support. The Company
also sells host adapters to end users through major computer product
distributors. The Company believes it has successfully positioned itself as a
leading supplier of SCSI-based solutions in both OEM and distributor channels.
 
     The Company focuses its worldwide marketing efforts on major OEM customers
and major distributors through its direct sales force located in the United
States and major industrial centers in Europe and the Far East. The Company also
makes selective use of sales representatives on a worldwide basis. OEM customers
include Conner Peripherals, Digital Equipment Corporation, Dell Computer
Corporation, Fujitsu, Hewlett-Packard Company, IBM Corporation, Intel
Corporation, Maxtor Corporation, NEC Technologies, Samsung, Seagate Technology,
Siemens and Toshiba America. Distribution customers include, Actebis, Anthem
Electronics, Gates/Arrow, Globelle, Ingram Micro, Merisel, Nissho, and Tech
Data. In fiscal 1995 and fiscal 1994 no customer accounted for more than 10% of
the Company's net revenues. In fiscal 1993, Apple Computer, Inc. accounted for
16% of the Company's net revenues, substantially all of which was derived from
the sale of the Company's discontinued laser printer controllers, and Maxtor
accounted for approximately 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 use by system
designers. The systems-level expertise and software experience of the Company's
engineering staff are also available to customers with
 
                                        4
<PAGE>   6
 
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 62%, 58% and 50% of
net revenues in fiscal 1995, 1994, and 1993, 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 primarily denominated in
U.S. dollars. As a result, the Company believes its corresponding foreign
currency risk is minimal.
 
BACKLOG
 
     The Company's backlog was approximately $65.6 million and $61.7 million at
March 31, 1995 and March 31, 1994, respectively. These backlog figures include
only orders scheduled for shipment within six months, of which the majority are
scheduled for delivery within 90 days.
 
     In the past, the Company has experienced delays in receipt of expected
purchase orders, and in some cases purchase orders have been rescheduled or
canceled due to changes in customer requirements. These changes may occur even
after the Company has been notified of design wins or has executed purchase
agreements with customers. The Company's customers may cancel or delay purchase
orders for a variety of reasons, including rescheduling of new product
introductions and changes in inventory policies and forecasted demand.
Accordingly, the Company's backlog as of any particular date may not be
indicative of the Company's actual sales for any succeeding fiscal period.
 
     The demand for the Company's products is strongly related to the demand for
high-performance microcomputers. This segment of the microcomputer industry is
continuing to experience significant growth due to migration of minicomputer
applications to microcomputers and the implementation of more complex business
applications. Should these rates of growth decline, the Company's revenues and
income may be adversely affected by a decrease in demand for the Company's
products, and pricing pressures could increase from both competitors and
customers.
 
COMPETITION
 
     In the personal and enterprise computing markets, the Company's principal
competitors are small, privately-held host adapter companies. The Company's
competitive strategy is 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 that it obtains a significant competitive advantage by supplying its
customers with a comprehensive array of I/O solutions ranging from connectivity
products for the personal computing market to high performance products for
enterprise-wide computing and networked environments. In addition, technical
leadership, product innovation, marketing expertise, and brand awareness
successfully position the Company in these markets.
 
     The Company's principal competitor in the mass storage market is Cirrus
Logic, Inc. The Company believes that its competitive strengths in the mass
storage market include its ability to obtain major design wins as the result of
its systems level expertise, integrated circuit design capability and
substantial experience in I/O applications. The Company believes the principal
competitive factors in design wins are performance, product features, price,
quality and technical and administrative support. Based on these factors, the
Company believes it has, in the past, successfully competed for design wins.
 
     The markets for the Company's products are highly competitive and are
characterized by rapid technological advances, frequent new product
introductions and evolving industry standards. The Company's competitors
continue to introduce products with improved performance characteristics and its
customers continue to develop new applications. The Company will have to
continue to develop and market appropriate products to remain competitive. While
the Company continues to devote significant resources to research and
development, there can be no assurance that such efforts will be successful or
that the Company will develop and introduce new technology and products in a
timely manner. In addition, while relatively few competitors offer a full range
of IOware solutions, additional domestic and foreign manufacturers may increase
their presence in, and the resources devoted to, these markets.

MANUFACTURING
 
     In August 1988, the Company opened its Singapore manufacturing facility for
the production and testing of high volume host adapter products. The Singapore
facility has earned ISO 9002 certification, a stringent quality standard that
has become a requirement for doing business globally. During fiscal 1995, the
Company purchased a fifth and sixth surface mount manufacturing line to support
its continued growth. In addition, the Company completed the move of its IC
production test facility to Singapore. This move affords the Company 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 static random access memory supplied by several outside
sources. An extended shortage or a major increase in the market prices of these
components could have an adverse affect on the Company's business. In addition,
foreign manufacturing is also subject to certain risks, including changes of
governmental policies, transportation delays and interruptions and the
imposition of tariffs and import and export controls. Currency exchange
fluctuations could increase the cost of components manufactured abroad, although
non-dollar denominated purchases do not currently represent a significant
portion of the Company's purchases. In addition, there is no assurance that the
Company will achieve its product cost objectives.
 
     All semiconductor wafers used to manufacture the Company's products are
processed to its specification by outside suppliers. The Company believes that
its current wafer volume and manufacturing technology requirements do not
justify owning and operating a fabrication facility. The Company's reliance on
third party semiconductor manufacturers involves several risks, including the
absence of guaranteed capacity, the possible unavailability of or delays in
obtaining access to certain process technologies, and the absence of control
over wafer delivery schedules, manufacturing yields and production costs. To
reduce these risks, in fiscal 1994 the Company entered into a deposit and supply
agreement with Taiwan Semiconductor Manufacturing Co., Ltd. Under this
agreement, the Company is entitled to guaranteed sub micron wafer foundry
capacity through June 1997 and as of March 31, 1995 is committed to $44.6
million of purchases over the remaining term of the contract. The Company has
made available to the supplier advances aggregating $14.7 million to secure the
supply of silicon wafers pursuant to this agreement. The advances are repayable
at the expiration of the supply agreement and the supplier has provided an
irrevocable standby letter of credit to the Company in an equal amount to
guarantee the repayment of amounts made available by the Company.
 
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, 1995, the Company had 1,697 employees, including 379 in
engineering, 871 in manufacturing (including 748 at its Singapore facility), 67
in customer technical support, 119 in marketing, 116 in sales, and 145 in
finance and administration. 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. None of the Company's employees is represented by a labor union.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Adaptec, Inc.:
 
     We have audited the consolidated balance sheet of Adaptec, Inc. (a
California corporation) and subsidiaries as of March 31, 1994, and the related
consolidated statements of operations, shareholders' equity and cash flows for
the years ended March 31, 1994 and 1993 (incorporated by reference herein).
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Adaptec, Inc. and
subsidiaries as of March 31, 1994, and the results of their operations and their
cash flows for the years ended March 31, 1994 and 1993 in conformity with
generally accepted accounting principles.

To Our Shareholders: Fiscal 1995 was an outstanding year for Adaptec. We posted
record revenues as we continued our worldwide leadership in the critical
input/output (I/O) market. We expanded our portfolio of innovative IOware
solutions. We made significant progress in applying our core competencies to
take advantage of the worldwide growth of the PC market. We made significant
investments to ensure Adaptec's participation in new markets that will grow
rapidly in the next few years.
<PAGE>   6

         For the year ended March 31, 1995, net revenues grew to $466,194,000, a
25 percent increase compared with fiscal 1994. Net income for fiscal 1995 was
$93,402,000, and net income per share was $1.75, representing a 58 percent
increase over the prior year.

         Our results reflect strong market demand and preference for our IOware
products. Host adapter revenue for the year grew by nearly 45 percent, as the
need for high-performance I/O solutions continued to increase. In the fourth
quarter, our annualized revenues exceeded half a billion dollars, a figure that
underscores Adaptec's standing as the industry leader in I/O solutions.

         As we broadened our portfolio of solutions for an evolving I/O market,
we both increased our market share, and helped to enlarge the overall market in
which we participate. We accomplished this in part by developing new products
that enhance our established I/O technologies, such as our industry leading
offerings in Small Computer System Interface (SCSI) products.

         For fiscal 1995 we set the objective to be the leader in
high-performance I/O solutions for Pentium-based systems. We achieved that goal
with the AHA(R)-2940 family of SCSI host adapter boards. This product delivers
SCSI solutions to PCs, network servers, and personal workstations using the new
high-performance system bus, 

                                       4
<PAGE>   7

Peripheral Component Interconnect, or PCI. After going through the fastest
production ramp-up in Adaptec's history, our PCI-to-SCSI product continues to
win a phenomenal reception with OEMs, system integrators and individual
consumers.

         A major new initiative that is driving our expansion into the
enterprise computing market is our Build a Better Server program. This program
introduces a family of new SCSI host adapters for the PCI bus, which enables
servers to connect as many as 21 peripherals per host adapter. Among these
solutions is Adaptec's first low-cost PCI Redundant Array of Inexpensive Disks
(RAID) adapter. Significantly, Build a Better Server also showcases Adaptec's
established software strengths with Adaptec CI/O(R) software, a suite of
powerful remote management and diagnostic tools that enable network
administrators to monitor SCSI subsystems on networks.

         Adaptec's market penetration and strong brand image are a winning
combination in the growing global marketplace. In Japan and Europe, demand for
all of Adaptec's host adapter products was strong across all performance ranges
and system architectures. Our strategy to forge a broader set of solutions is
also extending the Adaptec brand to reach an expanding network of distribution
channels throughout the world. Total SCSI unit volume grew significantly 

                                       5
<PAGE>   8


as our easy-to-use host adapters with menu-driven software utilities, increased
their penetration in desktop systems. This recognition is resulting in valuable
awareness and preference for our products at all distribution levels -- from
system integrators to corporate customers as well as computer retailers.

         In fiscal 1995 we continued to invest in furthering SCSI's position as
the microcomputer I/O solution that provides performance, data integrity and the
broadest choice of peripherals. Along with other industry leaders we announced
support for UltraSCSI, which doubles the available I/O bandwidth to 40 megabytes
per second.

         To expand our future opportunities for growth, we apply our core
competencies to new high-growth markets. For instance, we introduced network
interface cards (NICs), based on asynchronous transfer mode (ATM) technology.
ATM, widely believed to be the future in LAN and WAN networking, provides a
pathway for delivering emerging video and data-intensive applications. With
these and other products to relieve networking bottlenecks for desktop computers
and servers running bandwidth-intensive applications such as CAD/CAM,
distributed databases, and videoconferencing, Adaptec is strategically
positioned as a major force in the expanding high-speed networking market.

                                       6
<PAGE>   9


         As part of our ongoing strategy to bring promising new technologies to
market, we continued to invest in several emerging serial I/O technologies:
1394, Fibre Channel, and Serial Storage Architecture (SSA). To accelerate our
SSA product development, we entered into an agreement with IBM to license its
SSA technology. A licensing agreement with Apple Computer will enable us to use
Apple's FireWire technology as a basis for future 1394 products. We are jointly
developing Fibre Channel technology with Hewlett-Packard and others for very
high performance storage subsystems. This year, we also delivered wireless
infrared products for data transfer between portable and desktop PCs in order to
serve the needs of mobile office professionals.

         Meeting product demand with cost-effective, high-volume manufacturing
is key to Adaptec's long-term growth. We continue to invest in our Singapore
manufacturing facility to improve cycle times and expand our manufacturing
capabilities. To ensure capacity for future growth, we moved our ASIC production
test facility to Singapore and by fiscal year's end we installed our fifth and
sixth surface mount technology lines for board-level manufacturing.

         Regarding the fiscal 1996 outlook, we anticipate the industry
requirements for intelligent I/O to both support demand for our 

                                       7
<PAGE>   10

IOware solutions and create strong new market opportunities. We are committed to
being the lowest cost provider through focus on cost management and leveraging
our resources. Because our human resources are the source of our competitive
advantage, we will continue to significantly invest in employee training and
development. This has long been part of our corporate culture, and is an
important part of the reason that Adaptec continues to attract and retain such
outstanding and productive employees.

         As the PC industry produces more powerful platforms and demanding
applications, we expect I/O needs and solutions to evolve and grow. Adaptec has
the expertise in silicon design and software engineering and the industry
relationships to support current I/O requirements, and simultaneously prepare
for emerging solutions. As this year's annual report discusses in the following
sections, I/O is a dynamic, multi-faceted market. Adaptec has the technology,
the products, and the employee talent to provide for the I/O needs of today and
the future.

         The increased corporate use of groupware and distributed computing with
its client/server demands offers Adaptec another growth arena to extend its I/O
leadership. The Company's Build a Better Server program features a family of new
multichannel SCSI host adapters for the PCI bus, which enables servers to
connect as many as 21 peripherals per host adapter. Among these products is the
first low-cost Redundant Array of Inexpensive Disks (RAID) adapter.

         Besides SCSI, Adaptec's first efforts in a long-term strategy to
relieve bottlenecks in the high-speed networking market have resulted in the
development and shipment of a new family of hardware and software solutions
based on asynchronous transfer mode -- or ATM -- technology. Adaptec has
developed highly integrated proprietary ASICs for its ATM NICs and is verifying
its extensive ATM software applications for full interoperability with major ATM
switch and ATM network component providers.

         Finally, IOware solutions with new value-added software content

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


FISCAL 1995 COMPARED TO FISCAL 1994

Net revenues increased 25% to $466.2 million in fiscal 1995 from $372.2 million
in fiscal 1994. The continued adoption of SCSI in personal computers (PCs)
resulted in increased sales of the Company's SCSI host adapter products across
all performance ranges. Additionally, demand for the Company's host adapters was
driven by the growing use of file servers where SCSI usage approaches 100%.
During fiscal 1995, the Company introduced several new IOware solutions ranging
from connectivity products for the single-user and small-office markets, to
high-performance products for enterprise-wide computing and networked
environments. The market acceptance of the Company's high-performance host
adapters for the PCI local bus market resulted in the fastest product ramp in
the Company's history. The Company's fiscal 1995 revenue from mass storage
integrated circuits (ICs) was comparable to the prior year. The Company believes
this was due to the timing of design win cycles at Original Equipment
Manufacturers (OEMs) coupled with significant fluctuations in demand experienced
in the disk drive market. During fiscal 1995 the Company won key designs for
next generation products at major OEMs in the Pacific Rim.

     Gross margin of 56% in fiscal 1995 increased from 49% in fiscal 1994. Gross
margin was favorably affected by the increased revenues from the Company's
higher margin SCSI host adapters. The Company also continued to experience
component cost reductions and manufacturing efficiencies, including the move
of the IC production test facility to Singapore where costs are lower. This has
also allowed the Company to shorten the manufacturing cycle time and better
serve its customers. The Company's ability to maintain current gross margins
will be significantly affected by factors such as mix of products shipped,
competitive price pressures, the timeliness of volume deliveries of new
products, and the Company's ability to continue achieving manufacturing
efficiencies and component cost reductions.

     Research and development expenditures in fiscal 1995 were $60.8 million, an
increase of 52% over fiscal 1994. As a percentage of net revenues, research and
development expenses increased to 13% in fiscal 1995 compared to 11% in fiscal
1994. This was primarily due to increased staffing levels. The Company continued
to invest in its SCSI products, where it has captured a leadership position by
improving system performance as the computer industry has become more I/O
intensive with more powerful CPUs, multitasking operating systems, and a new
generation of intelligent peripherals. While SCSI solutions remain the core of
the Company's business, fiscal 1995 saw the Company broaden its portfolio of
solutions to include ATM, RAID, serial I/O and infrared technology. The Company
believes technical leadership and product innovation are its primary competitive
advantages and thus will continue to increase research and development
expenditures in fiscal 1996 to supply IOware products that deliver higher
performance in personal and enterprise-wide computing, and networked
environments.

     Sales and marketing expenses increased to $58.7 million in fiscal 1995, an
increase of 27% over fiscal 1994. As a percentage of net revenues, fiscal 1995
sales and marketing expenses were 13% compared to 12% in fiscal 1994. The
increase in actual spending was a result of increased staffing levels to support
the continued growth of the Company, including expansion of the Company's
international sales and marketing infrastructure. Additionally, increases in
advertising and promotional expenses were aimed at strategies to further
accelerate and expand SCSI acceptance in the marketplace and drive demand for
the Company's products. The Company believes that sales and marketing
expenditures will increase in fiscal 1996 as a result of continued increases in
staffing levels and through increased advertising and promotional activities
aimed at increasing demand for the Company's products.


                                       31
<PAGE>   34

     General and administrative expenses as a percentage of net revenues in
fiscal 1995 were consistent with fiscal 1994 at 5%. Actual spending increased
from fiscal 1994, primarily due to increased staffing to support the continued
growth of the Company. The Company believes that expenses will increase in
fiscal 1996, and will vary as a percentage of net revenues.

     Interest income, net of interest expense, was $6.8 million in fiscal 1995,
an increase of $2.9 million over fiscal 1994. The increase was primarily due to
the increase in cash and cash equivalents and marketable securities coupled with
slightly higher average yields on cash and investment balances.

     The Company's effective tax rate for fiscal 1995 was 25%, the same as
fiscal 1994. The Company's manufacturing subsidiary currently operates under a
tax holiday it has received from the Singapore government which expires in
September 1995. The Company is currently negotiating for an extension of this
tax holiday.

     The Company's results of operations may be affected in the future by a
variety of factors, including changes in product mix, competitive pricing
pressures, fluctuations in manufacturing yields, availability of components,
changes in product costs, timing of new product introductions and market demand
for these products, and cancellation or rescheduling of orders by its customers.
In addition, the Company's results from operations could be affected by
international and domestic economic conditions and technology changes in the
markets in which it competes.

FISCAL 1994 COMPARED TO FISCAL 1993

     Net revenues increased 20% to $372.2 million in fiscal 1994 from $311.3
million in fiscal 1993. The majority of the growth was from increased shipments
of the Company's SCSI host adapters, where adoption of SCSI in PCs and file
servers increased significantly. To meet the I/O intensive demands of file
server applications, the Company introduced and shipped several new
high-performance products during fiscal 1994 including products for local bus
architectures. The Company also experienced growth in shipments of its
proprietary single-chip SCSI host adapters, primarily to PC system and
peripheral manufactures. This expansion was due primarily to the increased use
of multitasking operating environments such as Novell NetWare and Microsoft
Windows, increased demand for multimedia PCs and increased shipments of SCSI
peripherals, especially CD-ROM drives. The Company also experienced increased
shipments of its mass storage ICs in fiscal 1994. The Company believes this
increase was primarily due to increased market share in high-capacity disk
drives that require an AT interface. Also during fiscal 1994, the Company
experienced a significant reduction in sales of laser printer controllers,
shipments of which the Company discontinued in September 1993.

     Gross margin of 49% in fiscal 1994 increased from 44% in fiscal 1993. Gross
margin was favorably affected by the mix of products shipped, primarily from
increased net revenues in the Company's SCSI host adapters and lower shipments
of the discontinued laser printer controllers. The Company also experienced
component cost reductions and increased manufacturing efficiencies that
contributed to the increased gross margin.

     Expenditures for research and development in fiscal 1994 were $40.0
million, an increase of 52% over fiscal 1993. As a percentage of net revenues,
research and development expenses increased to 11% in fiscal 1994 as compared to
9% in fiscal 1993. This was primarily due to increased staffing as the Company
continued to invest in its leadership position in the microcomputer I/O
industry. During fiscal 1994, the Company introduced new SCSI host adapters and
new mass storage ICs for the industry-standard AT (or ISA) bus and the emerging
PCI and VESA local bus architectures.

     Sales and marketing expenses increased to $46.2 million in fiscal 1994.
This represented a 42% increase from fiscal 1993 and an increase as a


                                       32
<PAGE>   35
percentage of net revenues to 12% from 10%. Contributing to the increase was
additional staffing to support a more complex business environment including the
establishment of a sales subsidiary in Japan. An additional factor was increased
advertising and promotional expenses aimed at increasing demand for the
Company's products in the distribution channel.

     General and administrative expenses as a percentage of net revenues in
fiscal 1994 were essentially the same as fiscal 1993 at 5%. Actual spending
increased 25% from fiscal 1993, primarily due to increased staffing to support a
higher level of activity in fiscal 1994.

     During the second quarter of fiscal 1994, the Company entered into a letter
agreement to settle a shareholder class action lawsuit. As a result, the Company
recorded an other expense of $2.4 million for settlement payments and costs
associated with this litigation.

     Interest income, net of interest expense was $3.9 million in fiscal 1994, a
25% increase from fiscal 1993. This was primarily due to a commensurate increase
in cash and cash equivalents and marketable securities from fiscal 1993 to
fiscal 1994. The Company's effective tax rate for fiscal 1994 was 25%, the same
as fiscal 1993.

LIQUIDITY AND CAPITAL RESOURCES

OPERATING ACTIVITIES Net cash generated from operating activities during fiscal
1995 was $118.1 million as compared to $43.1 million in fiscal 1994. During
fiscal 1995, the majority of funds generated from operations resulted from $93.4
million of net income adjusted by non-cash items including depreciation and
amortization of $15.7 million. Also contributing to favorable operating cash
flows was a decrease in net inventories of $7.2 million, and an increase in
accrued liabilities and accounts payable totaling $6.6 million. The decrease in
inventory is a result of improved marketing forecasts, coupled with continued
cost reductions and reduced manufacturing cycle times. The increase in accounts
payable and accrued liabilities is attributable to activities associated with
the year-to-year increases in net revenues. Other assets increased $4.1 million,
mostly related to an additional advance on a deposit and supply agreement the
Company signed during fiscal 1994 to support the Company's silicon wafer
requirements.

     During fiscal 1994, the majority of funds generated from operations
resulted from $59.0 million of net income adjusted by non-cash items including
depreciation and amortization of $11.5 million. Also contributing to the
positive results was an increase of $8.9 million in accrued liabilities.
Offsetting these were increases in net inventory of $5.6 million and accounts
receivable of $13.0 million. These increases were primarily the result of
activities associated with the year-to-year increase in net revenues. Other
assets also increased $11.5 million from fiscal 1993 to 1994. The most
significant portion of this increase was related to a deposit and supply
agreement the Company signed to support the Company's silicon wafer
requirements.

     In fiscal 1993, the Company's net cash generated from operating activities
was $42.6 million of which net income and non-cash items including depreciation
and amortization contributed $49.4 million and $7.0 million, respectively. Other
sources of cash were from an increase in accounts payable of $12.8 million to
support net revenues that more than doubled from the prior year and an increase
in accrued liabilities of $9.4 million. Uses of funds were for increased
accounts receivables and net inventories of $18.2 million and $11.8 million,
respectively, as a result of the year-to-year increase in net revenues.

INVESTING ACTIVITIES During fiscal 1995, the Company continued to invest in
equipment for product development and manufacturing testing, including the
addition of a fifth and sixth surface mount manufacturing line to support the
increased demand for board-level products. Additionally, during fiscal 1995,



                                       33
<PAGE>   36
the Company purchased land and buildings for $8.0 million to support staffing
requirements in engineering, sales and marketing. The Company also increased its
investment in marketable securities during the past year.

     During fiscal 1994, the principal investing activities for property and
equipment were for the addition of a surface mount manufacturing line,
manufacturing test equipment, engineering design tools and information systems
hardware and software. The Company also increased its investment in marketable
securities.

     During fiscal 1993, the Company completed the purchase of its Milpitas
headquarters, an additional building and land for $17.4 million. The Company
also made investments to increase its manufacturing capacity.

FINANCING ACTIVITIES During fiscal 1995, 1994 and 1993 the Company received
proceeds from common stock issued under the Company's Employee Stock Option and
Employee Stock Purchase Plans totaling $17.2 million, $13.5 million and $9.2
million, respectively. In fiscal 1995, the Company's Board of Directors approved
the repurchase of up to four million shares of the Company's common stock to be
used for issuance upon exercise of employee stock options previously granted or
to be granted in the future and for issuance under the Company's 1990 Stock
Plan. The Company repurchased two million shares for $36.5 million during fiscal
1995. In fiscal 1993, the Company also generated funds from a public offering of
common stock of $48.9 million and long-term debt financing of its building and
land purchases under a $17.0 million six year term loan.

     The Company anticipates capital expenditures in fiscal 1996 for equipment
for product development, manufacturing testing and information systems hardware
and software of approximately $30 million. The sources for these expenditures
are expected to be funds generated from operations as well as working capital
presently on hand. The Company may also require additional funds for increased
manufacturing capacity, technology investments, or acquisitions of complementary
businesses, products or technologies.

     The Company has an unsecured $17.0 million revolving line of credit under
which there were no outstanding borrowings as of March 31, 1995. The Company
believes that existing working capital, together with expected cash flows from
operations and available sources of bank and equipment financing, will be
sufficient to support the Company's anticipated operations at least through
fiscal 1996.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION AND TRANSLATION The consolidated financial
statements include the accounts of the Company and its wholly-owned subsidiaries
after elimination of intercompany transactions and balances. Foreign currency
transaction gains and losses are included in income as they occur.

REVENUE RECOGNITION The Company recognizes revenue generally at the time of
shipment or upon satisfaction of contractual obligations. The Company records
provisions for estimated returns at the time of sale.

FAIR VALUE OF FINANCIAL INSTRUMENTS The Company measures its financial assets
and liabilities in accordance with generally accepted accounting principles. For
certain of the Company's financial instruments, including cash and cash
equivalents, marketable securities, accounts receivable, accounts payable and
accrued expenses, the carrying amounts approximate fair value due to their short
maturities. The amounts shown for long-term debt also approximate fair value
because current interest rates offered to the Company for debt of similar
maturities are substantially the same.

MARKETABLE SECURITIES Effective April 1, 1994, the Company adopted Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities" (SFAS 115). This statement requires investments in
debt and equity securities to be classified as "held-to-maturity," "trading" or
"available-for-sale." As of March 31, 1995, the Company's marketable securities
are classified as available-for-sale and reported at fair value which
approximates amortized cost. Management determines the appropriate
classification of marketable securities at the time of purchase and reassesses
the classification at each reporting date. Marketable securities as of March 31,
1995 with maturities due after one year through three years totaled $71,905,000
with all remaining marketable securities maturing less than one year. Realized
gains and losses are based on the book value of specific securities sold and
were immaterial during fiscal 1995, 1994 and 1993. The cumulative effect of
adopting SFAS 115 was not material.

CONCENTRATION OF CREDIT RISK Financial instruments that potentially subject the
Company to significant concentrations of credit risk consist principally of cash
and cash equivalents, marketable securities and trade accounts receivable. The
Company places its marketable securities in a variety of financial instruments
such as municipal securities and U.S. Government securities. The Company, by
policy, limits the amount of credit exposure through diversification and highly
rated securities. Sales to customers are primarily denominated in U.S. dollars.
As a result, the Company believes its foreign currency risk is minimal.

     The Company sells its products to original equipment manufacturers and
distributors throughout the world. The Company performs ongoing credit
evaluations of its customers' financial condition and, generally, requires no
collateral from its customers. The Company maintains an allowance for
uncollectible accounts receivable based upon the expected collectibility of all
accounts receivable. There were no significant amounts charged to this allowance
during the current year.

INVENTORIES Inventories are stated at the lower of cost (first-in, first-out) or
market.

PROPERTY AND EQUIPMENT Property and equipment are stated at cost and depreciated
or amortized using the straight-line method over the estimated useful lives of
the assets.

INCOME TAXES Effective April 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS 109)


                                       39
<PAGE>   42
on a prospective basis. This adoption had no material effect on the Company's
financial statements.

     Under the asset and liability method of SFAS 109, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
temporary differences between the financial statement carrying amounts and the
tax basis of existing assets and liabilities measured using enacted tax rates
expected to apply to taxable income in the years in which the temporary
differences are expected to be recovered or settled. Under SFAS 109, the effect
on deferred tax assets and liabilities of a change in tax rates is recognized in
the income of the period that includes the enactment date. Previously, the
Company deferred the past tax effects of timing differences between financial
reporting and taxable income under Accounting Principles Board Opinion No. 11
"Accounting for Income Taxes," (APB 11).

NET INCOME PER SHARE Net income per share is computed under the treasury stock
method using the weighted average number of common and common equivalent shares
from dilutive options outstanding during the respective periods.

CASH AND CASH EQUIVALENTS Cash and cash equivalents consist of funds in checking
accounts, money market funds and marketable securities with original maturities
of three months or less.

RECLASSIFICATIONS Certain prior year amounts have been reclassified to conform
to the current year presentation.

NOTE 3. LINE OF CREDIT

The Company has available an unsecured $17,000,000 revolving line of credit
which expires on December 31, 1996. Of the total line of credit available,
$7,000,000 has been issued as an irrevocable standby letter of credit to
guarantee component purchases from a supplier (see Note 7) at a fee of 3/4% per
annum. As of March 31, 1995, no borrowings were outstanding under this line of
credit. The Company may select its own method of interest payment on borrowings
based upon the bank's CD rate plus one percent, Eurodollar rate plus one percent
or prime lending rate. A commitment fee of 1/4% per annum is payable on the
unused line of credit. In addition, the arrangement requires the Company to
comply with certain financial covenants. The Company was in compliance with all
such covenants as of March 31, 1995.

NOTE 4. LONG-TERM DEBT

The Company entered into a $17,000,000 term loan agreement in June 1992 bearing
interest at 7.65%, with principal and interest payable in quarterly installments
of $850,000. All outstanding principal and accrued but unpaid interest is due
and payable in June 1998. The arrangement requires the Company to comply with
certain financial covenants. The Company was in compliance with all such
covenants as of March 31, 1995. Principal payments due through the maturity on
the term loan are as follows:

NOTE 5. ACQUISITION

In February 1993, the Company acquired all of the outstanding shares of common
stock of Trantor Systems Limited (Trantor) in exchange for approximately 798,000
shares of the Company's common stock. Trantor developed and manufactured SCSI
host adapters and related software. The merger was accounted for as a pooling of
interests.

     Trantor's retained earnings and results of operations were not material to
the Company's consolidated financial statements. Consequently, the Company's
retained earnings at March 31, 1992 were restated to include the retained
earnings of Trantor without restating prior-period statements of operations. The
results of operations for Trantor for fiscal 1993 and thereafter have been
included in the Company's statements of operations.

NOTE 6. STOCK PLANS

1986 EMPLOYEE STOCK PURCHASE PLAN The Company has authorized 2,800,000 shares of
common stock for issuance under the 1986 Employee Stock Purchase Plan (1986
Plan). Qualified employees who have completed at least one quarter of continuous
service may elect to have a certain percentage (not to exceed 10%) of their
salary withheld pursuant to the 1986 Plan. The salary withheld is then used to
purchase shares of the Company's common stock at a price equal to 85% of the
market value of the stock at the beginning or ending of a three-month offering
period, whichever is lower. Under this Plan, 188,976 shares were issued during
fiscal 1995, representing approximately $3,104,000 in employee contributions.

1982 INCENTIVE STOCK OPTION PLAN This Plan was terminated by the Board of
Directors on May 1, 1990 and expired on January 1, 1992. However, the
termination and the expiration of this Plan has no effect on the vesting and
exercise rights of options already outstanding under the Plan. At March 31,
1995, there


                                       41
<PAGE>   44
were 6,000 exercisable options under this Plan at a price of $3.125 per share.

1990 STOCK PLAN The Company's 1990 Stock Plan allows the Board of Directors to
grant to employees, officers and consultants, options to purchase common stock
or other stock rights at exercise prices not less than 50% of the fair market
value on date of grant. The expiration of options or other stock rights is not
to exceed ten years after the date of grant. To date, the Company has issued
substantially all incentive and non-statutory stock options under this Plan at
exercise prices of 100% of fair market value on the respective dates of grant.
In general, options vest and become exercisable over a four year period.

     Option activity under the 1990 Stock Plan is as follows:

</TABLE>

     At March 31, 1995, there were 1,558,886 exercisable options under this Plan
at prices ranging from $2.47 to $21.50 per share.

     In August 1993, stock options issued by Trantor were exercised for 2,112
shares of common stock of the Company. These shares became issuable upon
exercise of certain stock options assumed by the Company in connection with the
acquisition of Trantor.

1990 DIRECTORS' OPTION PLAN The 1990 Directors' Option Plan provides for the
automatic grant to non-employee directors of non-statutory stock options to
purchase common stock at the fair market value on the date of grant, which is
generally the last day of each fiscal year except for the first grant to any
newly elected director. Each current director receives an option at the end of
each fiscal year for 10,000 shares, which vests and becomes exercisable over a
four year period. Each newly elected director receives an initial option on the
date of his or her appointment or election for 40,000 shares, which also vests
and becomes exercisable over a four year period. The options expire five years
after the date of grant.

     Option activity under the 1990 Directors' Option Plan is as follows:

RIGHTS PLAN The Company has reserved 120,000,000 shares of common stock for
issuance under the Rights Plan which was amended and restated as of June 30,
1992. Under this plan, shareholders will receive one Common Share Purchase Right
("Right") for each outstanding share of the Company's common stock. Each Right
will entitle shareholders to buy one share of common stock at an exercise price
of $50.00 per share. The Rights will trade automatically with shares of the
Company's common stock. The Rights are not exercisable until ten days after a
person or group announces acquisition of 20% or more of the Company's
outstanding common stock or the commencement of a tender offer which would
result in ownership by a person or group of 20% or more of the then outstanding
common stock.
  
     The Company is entitled to redeem the Rights at $.005 per Right anytime
on or before the tenth day following such an acquisition or tender offer. This
redemption period may be extended by the Company in some cases. If, prior to
such redemption, the Company is acquired in a merger or other business
combination, a party acquires 20% or more of the Company's common stock, a 20%
shareholder engages in certain self-dealing transactions, or the Company sells
50% or more of its assets, each right will entitle the holder to purchase from
the surviving corporation, for $50.00 per share, common stock having a then
current market value of $100.00 per share.

     At March 31, 1995, the Company has reserved the following shares of
authorized but unissued common stock:

     The Company's Singapore subsidiary has been granted pioneer status from the
Singapore government whereby all profits derived from the facility are tax
exempt for a period of eight years, subject to certain conditions. The pioneer
status will expire during fiscal 1996 and the Company will continue to benefit
from a reduced rate of 15% instead of the normal 27% for an additional three
year period. The Company is currently pursuing an extension of its pioneer
status with the Singapore government. As of March 31, 1995, the Company had not
accrued income taxes on $116,177,000 of accumulated undistributed earnings of
its Singapore subsidiary, as these earnings will be reinvested indefinitely.

REPORT OF MANAGEMENT

Management is responsible for the preparation and integrity of the consolidated
financial statements and other financial information presented in the annual
report. The accompanying financial statements were prepared in conformity with
generally accepted accounting principles and as such, include some amounts based
on management's best judgments and estimates. Financial information in the
annual report is consistent with that in the financial statements.

     Management is responsible for maintaining a system of internal business
controls and procedures to provide reasonable assurance that assets are
safeguarded and that transactions are authorized, recorded and reported
properly. The internal control system is continuously monitored by management
review, written policies and guidelines, and careful selection and training of
qualified people who are provided with and expected to adhere to the Company's
standards of business conduct. Management believes the Company's internal
controls provide reasonable assurance that assets are safeguarded against
material loss from unauthorized use or disposition and the financial records are
reliable for preparing financial statements and other data and maintaining
accountability for assets.

     The audit committee of the Board of Directors meets periodically with the
independent accountants and management to discuss internal business controls,
auditing and financial reporting matters. The committee also reviews with the
independent accountants the scope and results of the audit effort.

     The independent accountants, Price Waterhouse LLP, are engaged to examine
the consolidated financial statements of the Company and conduct such tests and
related procedures as they deem necessary in accordance with generally accepted
auditing standards. The opinion of the independent accountants, based upon their
audit of the consolidated financial statements, is contained in this annual
report.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Shareholders of Adaptec, Inc.:

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statement of operations, of cash flows and of shareholders' equity
present fairly, in all material respects, the financial position of Adaptec,
Inc. and its subsidiaries at March 31, 1995, and the results of their operations
and their cash flows for the year in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audit. We conducted our audit of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for the opinion expressed above. The financial statements of
Adaptec, Inc. as of and for the two years ended March 31, 1994 were audited by
other independent accountants whose report dated April 25, 1994 expressed an
unqualified opinion on those statements.
