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.

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.

<PAGE>   6



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

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


<PAGE>   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

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


<PAGE>   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


<PAGE>   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
<PAGE>   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


<PAGE>   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.

this Agreement or any other provision hereof or pursuant to any Ancillary
Agreement.

           SECTION 2.07. Unassignable Assets. Notwithstanding any other
provision of this Agreement or any of the Ancillary Agreements, but subject to
Section 8.02(q) hereof, to the extent that any of the Seller Contracts or any
other assets constituting part of the Purchased Assets are not assignable or
otherwise transferable to Purchaser and Sub, or if such assignment or transfer
would constitute a breach thereof or a violation of any applicable law, then
neither this Agreement nor such Ancillary Agreements shall constitute an
assignment or transfer (or an

<PAGE>   10

attempted assignment or transfer) thereof until such consent, approval or waiver
of such party or parties has been duly obtained. With respect to each Seller
Contract whose assignment or transfer to Purchaser or Sub requires the consent,
approval or waiver of another party thereto or any third party, Seller shall use
its best efforts to obtain such consent, approval or waiver of such other party

           SECTION 2.10. Further Assurances. In case at any time after the
Closing Date any further action is necessary or desirable to carry out the
purposes of this Agreement, each of the parties will take such further action
(including the execution and delivery of such further instruments and documents)
as any other party reasonably may request. Seller will sign and deliver any and
all instruments and documents necessary or appropriate to fully effect and
perfect the transfer or license, as the case may be, to Purchaser and Sub (or if

Assets.

           (a) Tax Assessments. There is no claim or assessment pending or, to
the knowledge of Seller or any branch of the Seller, threatened for any alleged
deficiency in Tax attributable to the affiliated group of which Seller is the
parent (the SELLER GROUP"), Seller, or any branch of the Seller relating to the
Business Assets, and neither Seller Group, Seller or any branch of the Seller
knows of any audit or investigation with respect to any liability of Seller for
Taxes attributable to the Seller Group, Seller or any branch of the Seller
relating to the Business Assets or any business activities related thereto.

           (b) No Tax Liens. There are (and as of immediately following the
Closing there will be) no material Encumbrances or charges of any sort on any of
the Business Assets relating to or attributable to Taxes.

           (c) Tax Exempt Use Property. None of the Business Assets are
"tax-exempt use property" within the meaning of Section 168(h) of the Internal
Revenue Code.

           SECTION 3.07. Title to and Condition of Purchased Assets and Third
Party Assets; Sufficiency of Business Assets.

           (a) Purchased Assets. Seller owns all the Purchased Assets and has
good and marketable title in and to all of the Purchased Assets, free and clear
of all material Encumbrances whatsoever, except Encumbrances listed in Section
3.07 of Seller's Disclosure Letter and the Cross-License Agreements listed in
Schedule 2A. Title to all the Purchased Assets is freely transferable from
Seller to Purchaser and Sub free and clear of all material Encumbrances without
obtaining the consent or approval of any person. All of the tangible personal
property included in the Purchased Assets is in good working condition and
repair, ordinary wear and tear excepted, and is suitable for the purposes for
which it is presently used. The current location of all tangible Purchased
Assets is set forth in Schedule 10, and Seller will not re-locate any material
tangible Purchased Assets from the location(s) shown for such Purchased Assets
on Schedule 10 without Purchaser's prior written consent. None of the Business
Assets (whether tangible or intangible) that were used in the Storage Products
Business as of December 31, 1997, which in the aggregate are material, have been
removed from use in such business since such date. The Tangible Asset Schedule
was prepared in the ordinary course, in a manner consistent with Seller's past
practice and in accordance with Seller's business records.

           (b) Third Party Assets. Those assets which constitute Third Party
Assets are identified as such on SCHEDULE 9 hereto. Seller has the right to
transfer the Third Party Assets, without restriction and without degradation to
the rights assigned. Seller has paid in full all royalties, fees and any other
payments that have ever become due and payable under all Seller Contracts or
related to any of the Third Party Assets and no further royalties, license fees,
maintenance and support fees or any other payments whatsoever are due and
payable, nor will any further royalties, license fees, maintenance and support
fees or any other payments whatsoever become due and payable in the future,
under any license agreements included among the Seller Contracts or with respect
to any Business Assets under any circumstances. Schedule 9 indicates the amount
owing and payment schedule, if any, with respect to Seller Contracts and Third
Party Assets.



                                       12
<PAGE>   13

           (c) Sufficiency of Business Assets. The Business Assets constitute
all assets, properties, rights and Intellectual Property Rights that are
necessary or required to enable Purchaser, following the Closing, to own,
conduct, operate and continue the Storage Products Business substantially as
historically conducted and as proposed to be conducted by Seller through the
Closing Date, other than the Retained Assets, without: (i) the need for
Purchaser to acquire or license any other asset, property or Intellectual
Property Right, (ii) the breach or violation of any contract or commitment, and
(iii) to Seller's knowledge, infringement of any Intellectual Property Right of
any party. Except as may be set forth in the Disclosure Letter or any schedule
to this Agreement, none of the Business Assets are licensed or leased from any
third party and no royalties, license fees or similar payments are due or
payable (or may become due or payable) to any third party under any license,
lease or other agreement. Except as set forth in Schedule 2B, none of the
Purchased Assets are licensed to any third party, including any Seller
Subsidiary or any other affiliate of Seller.

           SECTION 3.08. Seller Contracts. True and complete copies of the
documents listed in Schedule 9 have been made available to Purchaser. All Seller
Contracts are valid, in full force and effect, and enforceable in accordance
with their respective terms, and no party has repudiated or claimed a breach of
any provision thereof and no breach or default thereunder will result from this
Agreement, any of the Ancillary Agreements, or any of the transactions
contemplated hereby or thereby. Neither Seller nor, to the knowledge of Seller,
any other party to any Seller Contract is in material breach or default in
performance of any of their respective obligations thereunder, and no event
exists which, with the giving of notice or lapse of time or both, would
constitute a material breach, default or event of default on the part of Seller
or, to Seller's knowledge, on the part of any other party, to any Seller
Contract that is continuing unremedied. Those contracts, leases, licenses and
other agreements related to the Storage Products Business not listed in Schedule
10 are not in the aggregate material to the Storage Products Business.

           SECTION 3.09. No Restrictive Agreements. No Business Asset is bound
or affected by, any judgment, injunction, order, decree, contract, covenant or
agreement (noncompete or otherwise) that restricts or prohibits (or purports to
restrict or prohibit) Seller (or would restrict Purchaser) from freely engaging
in the Storage Products Business as now conducted or proposed to be conducted by
Seller through the Closing Date or from competing in the mass storage business
anywhere in the world (including without limitation any contracts, covenants or
agreements restricting the geographic area in which Seller may sell, license,
market, distribute or support any Products or Business Assets) (collectively,
"RESTRICTIVE AGREEMENTS") other than the Non-Competition Agreements between
Seller and Purchaser to be entered into concurrently with the execution of this
Agreement.

           SECTION 3.10. Litigation. There is no claim, action, suit,
arbitration, mediation, investigation or other proceeding of any nature pending
or, to the best of Seller's knowledge, threatened, at law or in equity, by way
of arbitration or before any court, governmental department, commission, board
or agency that: (i) may adversely affect, contest or challenge Seller's
authority, right or ability to sell or convey any of the Business Assets to
Purchaser or Sub hereunder or otherwise perform Seller's obligations under this
Agreement or any of the Ancillary Agreements; (ii) challenges or contests
Seller's right, title or ownership of any of the Business Assets or seeks to
impose an Encumbrance on, or a transfer of title or ownership of, any Business
Asset; (iii) asserts that any Business Asset, or any action taken by any
employee, consultant or 



                                       13
<PAGE>   14

contractor of Seller, any Seller Subsidiary or any other affiliate of Seller
with respect to any Business Asset, infringes or misappropriates any
Intellectual Property Rights of any third party; (iv) seeks to enjoin, prevent
or hinder operation of the Storage Products Business, the sale, license,
marketing or distribution of any of the Products or the consummation of any of
the transactions contemplated by this Agreement or any of the Ancillary
Agreements; (v) to the knowledge of Seller, would impair or have an adverse
affect on Purchaser's or Sub's right or ability to use or exploit any of the
Business Assets or impair or have an adverse effect on the value of any Business
Asset; or (vi) involves or relates to any potentially material claim against
Seller by any creditor of Seller related to the Storage Products Business. There
are no judgments, decrees, injunctions or orders of any court, governmental
department, commission, agency, instrumentality or arbitrator pending or binding
against Seller which affect any of the Business Assets or Purchaser's ability to
hire any Employee.

           SECTION 3.11. Compliance with Laws. Seller has complied in all
material respects with and has not received any notices of violation with
respect to, any Irish, United States or non-U.S., federal, state or local
statute, law or regulation (including any Environmental Law) applicable to the
Storage Products Business or any of the Business Assets.

           SECTION 3.12. No Representation to Employees. Seller has made no
representation to any employee, consultant or contractor of Seller, any Seller
Subsidiary or any other affiliate of Seller that Purchaser can or will terminate
the employment of its employees only upon certain terms or conditions or only on
certain grounds or that such employment is anything other than "at will".

           SECTION 3.13.  Employees.

           (a) Employee List. Set forth in SCHEDULE 13 is a complete and
accurate list of all the employees of Seller, any Seller Subsidiary or affiliate
of Seller who work in the Storage Products Business. Schedule 13 also contains a
complete and accurate list of all consultants currently hired, retained or
engaged by Seller or by any Seller Subsidiary or any other affiliate of Seller
to perform any work or services related to the Products and/or the Storage
Products Business (collectively "CONSULTANTS" and each individually a
"CONSULTANT"). Seller has provided to Purchaser a true and accurate list of all
locations at which Employees (as defined in Section 6.01) and/or Consultants are
working as of the date hereof. With respect to "New Hires" (as defined in
Section 6.01), Schedule 13 also contains the date of hire and years of
employment or service. Seller has provided to Purchaser a true and accurate list
for each New Hire of the current annual base salary and (in the case of
Consultants) current compensation arrangement for each Consultant, their status
as exempt or non-exempt, all sick or vacation benefits accrued or payable, all
bonuses, profit sharing, or commissions accrued or payable, any special
compensatory or reimbursement arrangements, comp time or other arrangements with
such Employees and any other compensatory agreements between such Employee and
Seller. In addition, Seller has provided to Purchaser a list of all employees or
Consultants no longer providing services to Seller who did work in the Storage
Products Business at any time on or after January 1, 1995.

           (b) Employment and Consulting Agreements. Schedule 13 includes a
complete and accurate list of (i) all employment contracts, agreements or
arrangements with or related to any 



                                       14
<PAGE>   15

New Hire (if any) that are (or will prior to the Closing be) in effect and (ii)
all consulting or similar agreements related to any Consultant that are (or will
at the Closing be) in effect.

           (c) No Terminations Planned; No Restrictions. Seller has not received
any notice, nor, to Seller's knowledge is there any reason to believe, that any
executive or key employee of or Consultant to the Storage Products Business unit
or any group of employees working on or contributing to the Storage Products
Business has any plans to terminate his, her or their employment with Seller. To
Seller's knowledge, no such executive or key employee or Consultant is subject
to any agreement, obligation, order or other legal hindrance that impedes or
might impede such executive or key employee from devoting his or her full
business time to the affairs of Seller prior to the Closing Date and, if such
person becomes an employee of Purchaser, to the affairs of Purchaser after the
Closing Date.

           SECTION 3.14. Pension and Employee Benefit Matters. Neither Seller
nor any entity which, within the last 5 years, has been under common control of
or affiliated with Seller (an "ERISA AFFILIATE") within the meaning of Section
414(b), (c) or (m) of the Internal Revenue Code, has ever been obligated to
contribute to any "multi-employer plan" as such term is defined in Section 3(37)
of ERISA. No material liability to the Pension Benefit Guaranty Corporation is
expected to be incurred in connection with the transactions contemplated hereby.
SCHEDULE 13 includes a true and complete list of all Employees, who are or may
become entitled to benefits under any severance agreement as of the Closing
(other than an arrangement generally applicable to all or substantially all
Employees), and the terms thereof.

           SECTION 3.15. Supplier and Customer Relationships. To date no
Products have been sold. SCHEDULE 14 lists the potential customers who are
currently evaluating prototypes of the Products, whether pursuant to written
beta test, submission or evaluation agreements (collectively "EVALUATION
AGREEMENTS") with Seller or otherwise. Seller has good commercial working
relationships with its suppliers for the Storage Products Business and since
January 1, 1997, no supplier accounting for two percent (2%) or more of Seller's
purchases of supplies related to the Storage Products Business has canceled or
otherwise terminated its relationship with Seller, decreased or limited
materially its materials supplied to Seller from the corresponding period in
1996, or, to Seller's knowledge, threatened to take any such action.

           SECTION 3.16. Product Liability. Neither Seller nor any Seller
Subsidiary has any Liability (and, to Seller's knowledge, there is no basis for
any present or future action, suit, proceeding, hearing, investigation, charge,
complaint, claim or demand against Seller or any Seller Subsidiary or any
affiliate of Seller giving rise to any Liability) arising out of any injury to
individuals or property as a result of the ownership, possession or use of any
Product or prototype of any Product manufactured or delivered by Seller or any
Seller Subsidiary or any affiliate of Seller prior to the Closing Date.

           SECTION 3.17.  Intellectual Property Rights.

           (a) Ownership. Seller is the sole and exclusive owner or has the
right to use the Key Assets pursuant to license, sublicense, agreement, or other
valid permission, all Intellectual Property Rights necessary or desirable for
the operation of the Storage Products Business as presently conducted and as
presently proposed to be conducted, except for those Intellectual 



                                       15
<PAGE>   16

Property Rights incorporated into or forming a part of or critical to the
development, manufacture or use of the Products identified on the applicable
Schedules as being licensed to Seller by third parties, and except for rights
granted to Seller under the Cross License Agreements. Except for rights granted
to Seller under the Cross-License Agreements, each Intellectual Property Right
owned, licensed to or used by Seller in the Storage Products Business
immediately prior to the Closing Date hereunder will be owned or licensed to and
available for use by Purchaser and Sub in the identical manner used by Seller as
of December 31, 1997 with respect to read channel and pre-amp product
development.

           (b) Assets Sufficient. To Seller's knowledge, except as indicated in
Schedule 2A, the Business Assets include all assets, properties and Intellectual
Property Rights necessary to enable Purchaser and Sub to continue to develop and
test the Products in identical manner of Seller's Product developing and
testing. Except as indicated in Schedule 2A, to Seller's knowledge, the Business
Assets include all assets, properties and Intellectual Property Rights necessary
to enable Purchaser and Sub to manufacture, use, and sell the Products, provide
technical support therefor and to conduct the Storage Products Business in the
manner in which such business was conducted by Seller on December 31, 1997, and
as such business is proposed to be conducted through the Closing Date.

           (c) No Infringement. The Products and, as and to the extent used in
the development of or integrated or incorporated in the Products, the Key Assets
and other Business Assets have not infringed or violated and currently do not
infringe or violate upon, or misappropriate any copyright, mask work or trade
secret, or to Seller's knowledge, any patent or other intellectual property
rights (other than trademarks) of any third party, and no third party has
asserted or threatened to assert against Seller any claim of infringement or
misappropriation of any such rights. To Seller's knowledge, no third party has
interfered with, infringed upon, misappropriated, or otherwise come into
conflict with any of the Intellectual Property Rights in any manner affecting
the Storage Products Business. None of the Intellectual Property Rights is owned
by or registered in the name of any current owner (other than Seller) or former
owner, shareholder, partner, director, executive, officer, employee, salesman,
agent, customer, contractor or representative of Seller; nor does any such
person have any interest therein or right thereto, including (but not limited
to) the right to royalty or other payments. No other representation or warranty
in this Section 3.17 shall be deemed to cover matters covered by this Section
3.17(c).

           (d) Recorded Intellectual Property Rights and Licenses. Schedules 5,
1, 4 and 2B, when taken together, identify: (i) each Listed Patent Asset, Listed
Copyright Asset, and mask work (and/or registration thereof) which has been
granted or registered and issued to Seller in any jurisdiction, (ii) each
pending Listed Patent Asset application or application for registration of a
Listed Copyright Asset, Product mask work or similar right which Seller has made
in any jurisdiction, (iii) all unregistered copyright works and mask works
included within the Technology Deliverables and (iv) each license, agreement, or
other permission which Seller has granted to any third party with respect to any
Purchased Assets or, to the extent that they relate to the Products or their
development, the Licensed Assets. Seller has delivered to Purchaser correct and
complete copies of all such patents, patent applications, copyrights and mask
work registrations covering the Product Designs and all applications, licenses,
agreements and permissions (as amended to date) required to make, use or sell
Products, other than the Cross License Agreements listed in Schedule 2A, for
which Seller has provided Purchaser with 



                                       16
<PAGE>   17

accurate abstracts of the license grants by Seller, and Seller has made
available to Purchaser correct and complete copies of all other written
documentation evidencing ownership or other rights of Seller, as the case may
be, of each such item. Seller has provided Purchaser with accurate abstracts of
the Cross-License Agreements listed in Schedule 2B. Seller has not filed any
copyright or mask work registrations or applications therefore related to the
Storage Products Business in the United States or any foreign country. Except
for rights licensed to the Seller pursuant to the Cross-License Agreements,
Seller has the exclusive right, to the extent such right exists, to file,
prosecute, and maintain patent applications and applications to register
copyrights and mask works related to or included in the Key Assets and the
patents and registrations that issue therefrom. All fees to maintain Seller's
rights in the Intellectual Property Rights in and to the Purchased Assets that
are due on or before the Closing Date, including (without limitation)
registration, maintenance and prosecution fees, and all professional fees
incurred in connection therewith, have been paid.

           (e) Restrictions. With respect to each Intellectual Property Right,
license, agreement or other permission required to be identified in Schedules 1,
4, 5 and 9, to the extent that the subject Intellectual Property Right covers or
embodies Purchased Assets: (i) Seller possesses all right, title and interest in
and to such Intellectual Property Right, license, agreement or permission free
and clear of any Encumbrance or other restriction; and (ii) no action, suit,
proceeding, hearing, investigation, complaint, claim or demand is pending or, to
Seller's knowledge, is threatened, which challenges the legality, validity,
enforceability, use or ownership of such Intellectual Property Rights, license,
agreement or permission.

           (f) Licenses. Except for rights licensed by Seller pursuant to the
Cross-License Agreements, Schedule 9 and Schedule 2A set forth and summarize
each license Seller has granted to any third party with respect to the Key
Assets in connection with the manufacture, use or sale of Products for Storage
Peripherals. Such Schedules 9 and 2A also sets forth and summarizes each
Intellectual Property Right that a third party owns and that Seller uses
pursuant to a license, sublicense, agreement or other permission in connection
with the manufacture, use or sale of Products. Except for the Cross-License
Agreements, Seller has delivered to Purchaser correct and complete copies of all
such licenses, sublicenses, agreements, and permissions (as amended to date).
With respect to each Intellectual Property Right required to be identified in
such Schedule 9, except for rights under the Cross-License Agreements: (i) the
license, sublicense, agreement or permission covering the item is legal, valid,
binding, enforceable and in full force and effect; (ii) the license, sublicense,
agreement or permission will continue to be legal, valid, binding, enforceable
and in full force and effect on identical terms to Purchaser's and Sub's benefit
immediately following the Closing and all consents to the assignment of each
Seller Contract (including without limitation each Seller Contract that is a
license, sublicense, agreement, permission or covenant not to compete together
with all Intellectual Property Rights relating thereto) needed to assign any
such Seller Contract to Purchaser and/or Sub or any other subsidiary of
Purchaser designated by Purchaser have been obtained or will be obtained prior
to Closing; (iii) the license, sublicense, agreement or permission does not
restrict Seller's ability to do business in any jurisdiction or with respect to
the read channel and preamp market or industry; (iv) Seller is not in breach or
default of, and to Seller's knowledge, no other party to any such license,
sublicense, agreement or permission is in breach or default of, and no event has
occurred which, with notice or lapse of time or both, would constitute a breach
or default of, or permit 



                                       17
<PAGE>   18

termination, modification or acceleration of, any such license, sublicense
agreement or permission; (v) to Seller's knowledge, no party to the license,
sublicense, agreement or permission has repudiated or contested any provision
thereof; (vi) with respect to each sublicense, to Seller's knowledge, the
representations and warranties set forth in clauses (i) through (v) above are
true and correct with respect to the underlying license; (vii) no action, suit,
proceeding, hearing, investigation, complaint, claim, or demand is pending to
which Seller is a party, participant or recipient or, to Seller's knowledge, is
threatened which challenges the legality, validity or enforceability of any such
license, sublicense, agreement or permission or any Intellectual Property Right
governed thereby; and (viii) except as provided in Schedule 2B, Seller has not
granted any sublicense or similar right with respect to the license, sublicense,
agreement or permission related to the manufacture, use or sale of Products.
Neither Seller, nor any Seller Subsidiary nor any affiliate of Seller is liable
for, or has made any contract or arrangement whereby it may become liable to,
any person for any royalty, fee or other compensation for the ownership, use,
license, sale, distribution, manufacture, reproduction or disposition of any
Purchased Asset or any Licensed Asset. Except as provided in Schedule 2A, no
person other than Seller holds any license or other right granted or authorized
by or received from Seller or any affiliate or predecessor in interest to Seller
to manufacture, modify, distribute or market any of the Products or has granted
rights under the Intellectual Property Rights pertaining to Product Designs. No
person (other than Purchaser and Sub) will be or become entitled to receive a
copy of source code of any software or other tangible deliverable included among
the Purchased Assets as a result of this Agreement, any Ancillary Agreement or
any other agreement or transaction contemplated by this Agreement and no person
holds or has been granted access to any copy of source code of any software or
Confidential Information constituting or constituted in a Key Asset other than
Confidential Information that is customarily shared with customers and potential
customers of products like the Products.

           (g) Employee Invention Agreements. All employees, contractors and
consultants of Seller, any Seller Subsidiary or any other affiliate of Seller
(including but not limited to all the Employees and all the Consultants) and any
other third parties who have been involved in the development of any Product or
any Purchased Asset, have executed invention assignment and confidentiality
agreements in the form delivered to Purchaser's counsel, and all employees and
consultants of Seller who have access to confidential information or trade
secrets authored, created or developed in the conduct of the Storage Products
Business and/or the Purchased Assets have executed nondisclosure agreements in
the form delivered to Purchaser's counsel. Seller has taken reasonable steps,
consistent with industry standards, to protect the secrecy and confidentiality
of all nonpublic information pertaining to the Products and other Key Assets,
the secrecy of which is customarily protected in the semiconductor device
industry, including (without limitation) the marking of all Seller Confidential
Information (as defined below) with appropriate "Proprietary" or "Confidential"
legends, the establishment of policies for the handling, disclosure and use of
confidential or propriety information and the acquisition of valid written
non-disclosure agreements from any party receiving the same.

           (h) Nondisclosure Agreements. No third party is in possession of any
confidential information pertaining to the design of any Product, except for
prototype evaluation units provided by Seller to potential customers. Seller has
not knowingly taken or knowingly failed to take any action that, directly or
indirectly, has caused any Listed Patent Assets or Listed 



                                       18
<PAGE>   19

Copyright Assets to enter the public domain, or has in any way affected its
absolute and unconditional ownership of Intellectual Property Rights in and to
the Product Designs. All use, disclosure or appropriation of confidential or
proprietary information related to the Storage Products Business not owned by
Seller has been pursuant to the terms of a written agreement between Seller and
the owner of such information, or is otherwise lawful.

           (i) Seller Contracts. Except as provided in Schedule 9, the Seller
Contracts include all contracts or licenses to which Seller is or has been a
party or, to Seller's knowledge, that are or may be necessary for Purchaser and
Sub to hold in order to operate the Storage Products Business after the Closing
and/or to manufacture, have manufactured, use, sell, lease, license, market,
distribute, install, service, support or otherwise commercially exploit any or
all of the Products or, subject to the Technology and Patent License Agreement,
Purchased Assets without: (i) the need to purchase, license or acquire any other
asset or property that is the subject of a Seller Contract; (ii) violating any
contractual rights of any third party; or (iii) to Seller's knowledge,
infringing, misappropriating or misusing any software, technology, Industrial
Property or Intellectual Property Rights of any third party.

           (j) Status of Product Development. Seller has in all material
respects made a full, complete and accurate disclosure to Purchaser regarding
the state of development of the Products and the use of development tools and
other development resources used by Seller (and Seller's contract personnel) in
the development of the Products.

           (k) Product Compliance. All of the Products will perform (including
but not limited to the processing of any data) in the same manner during and
after the year 2000 as they do before the year 2000, without the need to modify
or alter any of such Products in any respect.

           (l) No Government Funding. No governmental or third party funding,
grants or resources were utilized in connection with designing, developing or
manufacturing the Products or otherwise conducting the Storage Products Business
and no governmental entity has any rights in or to any of the Key Assets,
Products or Intellectual Property Rights related thereto.

           SECTION 3.18. Brokers. Neither Seller, any Seller Subsidiary nor any
of their affiliates has employed any broker, finder, investment banker or agent,
incurred or agreed to pay any brokerage fee, finder's fee or commission with
respect to the transactions contemplated by this Agreement, or dealt with anyone
purporting to act in the capacity of a broker, finder, investment banker or
agent with respect thereto.

           SECTION 3.19.  Environmental Matters.

           (a) Environmental Obligations. Seller, each Seller Subsidiary and
each other affiliate of Seller is conducting, and at all times has conducted,

Seller, any Seller Subsidiary or any other affiliate of Seller, or any of their
predecessors-in-interest (collectively, the "FACILITIES"), in accordance with
and in material compliance with all Environmental Laws.

           (b) No Outstanding Orders or Actions. There are no outstanding
orders, injunctions or decrees against Seller, nor are there any pending or
threatened investigations of any kind against Seller, related to the Storage
Products Business concerning any Environmental Laws.

           (c) No Waste Disposal. All Hazardous Substances and waste materials
generated, used, transported, treated, stored or disposed of in connection with
the Storage Products Business have been handled, stored, treated and disposed of
in accordance with applicable Environmental Laws.

           SECTION 3.20. Insurance. Seller has policies of insurance (i)
covering risk of loss on the Purchased Assets, (ii) covering liability for fire,
property damage and personal injury, and (iii) for business interruption. All
such insurance policies are valid, in full force and effect and enforceable in
accordance with their respective terms and will be maintained in effect until
the Closing Date.

           SECTION 3.21. Disclosure. Seller has fully provided Purchaser with
all the information (orally or in writing) that Purchaser has reasonably
requested for deciding whether to enter into this Agreement and the transactions
contemplated hereby, including (but not limited to) the status of product
development. This Agreement, the Schedules attached hereto, the Seller
Disclosure Letter, the Seller Closing Documents and the Ancillary Agreements,
and all other information (oral and written) relating to the Products and the
Storage Products Business delivered in connection herewith, when taken together,
do not contain any untrue statement of a material fact or omit to state a
material fact required to be stated herein or therein or necessary to make the
statements herein or therein, in light of the circumstances in which they were
made, not misleading.

                                   ARTICLE IV

                   REPRESENTATIONS AND WARRANTIES OF PURCHASER

           Purchaser hereby represents and warrants to Seller that all of the

           SECTION 4.01. Organization and Good Standing. Each of Purchaser and
Sub is a corporation duly organized, validly existing and in good standing under
the laws of its jurisdiction and is in good standing under the laws of its

           SECTION 4.02. Authorization. All corporate action on the part of each
of Purchaser and Sub, its officers and directors necessary for the
authorization, execution and delivery of this Agreement, the Ancillary
Agreements and the Purchaser Closing Documents, the performance of all
obligations of Purchaser and Sub hereunder and thereunder, has been taken or
will be taken prior to the Closing. This Agreement and the Non-Competition
Agreements constitute, and the other Ancillary Agreements and the Purchaser
Closing Documents when executed and delivered, will constitute, valid and
legally binding obligations of Purchaser and Sub, as applicable,



                                       20
<PAGE>   21

enforceable in accordance with their respective terms, except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of
general application affecting enforcement of creditors' rights generally and
(ii) as limited by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies. The execution, delivery and
performance by each of Purchaser and Sub of this Agreement and each of the
Ancillary Agreements, as applicable, have been duly and validly approved by its
Board of Directors. No approval of the stockholders of Purchaser or Sub is
required to effect the transactions contemplated by this Agreement, the
Ancillary Agreements or the Purchaser Closing Documents.

           SECTION 4.03. Governmental Consents. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or

in connection with the consummation of the transactions contemplated by this
Agreement, except for compliance with the HSR Act and the Mergers Act.

           SECTION 4.04. Litigation. There is no action, suit, proceeding or
investigation pending or currently threatened against Purchaser or Sub that
questions the validity of this Agreement, the Ancillary Agreements or the
Purchaser Closing Documents, or the right of Purchaser or Sub to enter into this
Agreement, the Ancillary Agreements or the Purchaser Closing Documents or to
consummate the transactions contemplated hereby or thereby.

           SECTION 4.05. Compliance with Other Instruments and Laws. The
execution, delivery and performance of this Agreement, the Ancillary Agreements
and the Purchaser Closing Documents by each of Purchaser and Sub and the
consummation of the transactions contemplated hereby and thereby do not and will
not result in a violation or default in any material respect of: (a) any
provision of the charter documents of Purchaser or Sub, or (b) any judgment,
order, writ, or decree applicable to the assets of Purchaser or Sub, or (c) or
constitute a default (or event which with the giving of notice or lapse of time,
or both, would become a breach, violation or default) under any material
contract to which it is a party. Neither Purchaser nor Sub is in violation or
default in any material respect of any provision of its charter documents, or of
any instrument, judgment, order, writ, decree or contract to which it is a party
or by which it is bound that could reasonably be expected to have a material
adverse effect on its business, or, to the best of its knowledge, of any
provision of any federal or state statute, rule or regulation applicable to it
that could reasonably be expected to have a material adverse effect on it.

           SECTION 4.06. Brokers. Neither Purchaser, Sub nor any of their
affiliates has employed any broker, finder or agent, incurred or agreed to pay
any brokerage fee, finder's fee or commission with respect to the transactions

capacity of a broker, finder or agent with respect thereto.

                                    ARTICLE V

                                    COVENANTS

           SECTION 5.01. Conduct of Business Prior to the Closing. Seller
covenants and agrees that, between the date hereof and the Closing Date, it will
(except as Purchaser otherwise agrees in its sole discretion, which as to clause
(d) below will not unreasonably be withheld):

           (a) not sell, transfer, assign, convey, license, move, relocate,
encumber or otherwise dispose of any of the Business Assets or permit any Seller
Subsidiary or any other affiliate of Seller to do so;

           (b) conduct, at Seller's expense, the Storage Products Business in
the ordinary course and consistent with Seller's past practice (taking into
account the sale of the Business Assets contemplated hereby and Seller's other
agreements hereunder) except for such actions of Seller as may be contemplated
by this Agreement or agreed to by Purchaser in a writing signed by Purchaser;

           (c) not transfer any Employee (as defined in the first sentence of
Section 6.01(a)) to any other division or position of employment within Seller
or any of Seller's Subsidiaries or any other affiliates of Seller;

           (d) not terminate the employment of any Employee (as defined in the
first sentence of Section 6.01(a));

           (e) not encourage or otherwise act to cause any Employee not to
accept any offer of employment by Purchaser made pursuant to Section 6.01
hereof;

           (f) not change the base salaries or bonus programs of any Employee or
establish a bonus plan or any new employee benefits for any Employee without
Purchaser's prior written approval;

           (g) continue to provide Purchaser with reasonable access to and the
opportunity to meet and interview each Employee for the purpose of negotiating
offers of employment contingent upon the consummation of the sale and transfer
of the Business Assets to Purchaser and Sub and the other transactions
contemplated hereby (Seller expressly acknowledges that it consents to such
activities undertaken by Purchaser prior to the Effective Date);

           (h) use Seller's best efforts to secure and preserve good and
marketable title in Seller's name in and to all of the Business Assets, free of
all material Encumbrances, and to cause the conditions to Closing set forth in
Article VIII to be fulfilled as promptly as possible;

           (i) terminate any license rights held by any Seller Subsidiary or any
other affiliate of Seller with respect to any of the Purchased Assets; and

           (j) terminate or cause to be released or expunged all Encumbrances on
any Purchased Assets.



                                       22
<PAGE>   23

           SECTION 5.02. Interim Sales Representation and Marketing Cooperation.

           (a) Appointment as Interim Period Sales Representative. Seller hereby
authorizes Purchaser, between the Effective Date and the earlier of (i) the
Closing Date or (ii) the termination of this Agreement in accordance with its
terms (the "INTERIM PERIOD"), to market and to act as a sales representative for
Products on the terms and conditions of the existing Joint Marketing and Sales
Representative Agreement between Purchaser and Seller, dated December 1, 1997,
which agreement shall remain in full force and effect until the Closing, at
which time it shall be terminated.

           (b) Recognition of Revenue Accruing Pre and Post Closing. No sales of
the Products have occurred to date and none are expected to occur prior to the
Closing Date. Revenues accrued per GAAP as a result of deliveries after Closing
of Products sold in connection with Evaluation Agreements existing prior to the
Closing Date will be for Purchaser's account, and Seller will not be entitled to
any compensation with respect thereto, except as expressly provided in Sections
2.03(b) and (d).

           (c) Seller Non-disturbance of Prospects. To avoid impairing
negotiations between Purchaser and any prospective customer ("PROSPECT"),
neither Seller nor any Seller Subsidiary nor any person or entity acting upon
Seller's or any Seller Subsidiary's instructions will, without Purchaser's prior
written consent, contact any such Prospects, or cause to be communicated to any
such Prospect any proposal with respect to any Product, except that Seller will
upon Purchaser's request cooperate with Purchaser in dealing with each Prospect.
If Purchaser ceases to actively pursue any Prospect as a customer for Products,
Purchaser will so notify Seller in which case the restrictions of this
subsection will cease to apply as to the Prospect specified in such notice.

           (d) Assumption and Disclaimer as to Obligations. All Liabilities
arising under any Evaluation Agreement existing prior to the Closing Date will
be Excluded Liabilities except as expressly provided in this clause (d). If
Closing never occurs, Purchaser will never have and will not assume any
Liabilities or obligations under any Evaluation Agreement, and all such
Liabilities or obligations will remain Excluded Liabilities. If Closing does
occur, then notwithstanding anything in Article II hereof to the contrary, each
Evaluation Agreement shall become an Seller Contract. In no event will Purchaser
be liable or responsible for paying any of Seller's sales personnel in
connection with any transactions contemplated by this Section 5.02.

           SECTION 5.03. Consent of Third Parties. Prior to the Closing Date,
Seller shall obtain the consent in writing of all persons, if any, necessary to
permit Seller to assign and transfer all of the Purchased Assets (including, but
not limited to, the Seller Contracts) to Purchaser, free and clear of all
material Encumbrances.

           SECTION 5.04. Future Agreements. In the event Seller enters into any
material agreement between the date of this Agreement and the Closing that
relates to the Storage Products Business or Products, at the request of
Purchaser, Seller agrees to include any such agreement within the Seller
Contracts.



                                       23
<PAGE>   24

           SECTION 5.05. Certain Notifications. At all times prior to the
Closing, Seller shall promptly notify Purchaser in writing of the occurrence of
any event which will result, or has a reasonable prospect of resulting, in the
failure to satisfy any of the conditions specified in Article VIII hereof.

           SECTION 5.06. Post-Closing Access to Information. If, after the
Closing Date, in order properly to operate the Storage Products Business or
utilize the Business Assets, or prepare documents or reports required to be
filed with governmental entities or prepare Purchaser's or Sub's financial
statements for the Storage Products Business, it is reasonably necessary that
Purchaser obtain additional information within Seller's possession relating to
the Storage Products Business or the Business Assets, Seller shall furnish or
cause its representatives to furnish such information to Purchaser as promptly
as possible. Such information shall include, without limitation, all agreements
between Seller and any person relating to the Storage Products Business or the
Business Assets. Seller agrees to maintain any and all information and records
regarding its business and operations which are not transferred to Purchaser
pursuant to this Agreement necessary to permit Purchaser to calculate the
availability to it of Tax credits for increasing research activities under
Section 41 of the Internal Revenue Code. Seller shall maintain and make
available the information and records specified in this Section for a period of
seven (7) years after the Closing Date.

           SECTION 5.07. Payroll Information. Following execution of this
Agreement, Seller will notify Purchaser of the name, telephone, fax and
electronic mail address of the Seller employee who is principally responsible
for administering payroll for the Employees. Seller shall use its best efforts
(to the extent practicable) to provide to Purchaser, within five (5) days of the
Closing Date, all W-2 information for calendar 1998 with respect to each United
States Employee and all information regarding Seller's payments for unemployment
insurance (including FUTA and SDU), paid by Seller in respect of each United
States Employee and similar information with respect to each non-U.S. Employee,
as required by the applicable jurisdiction.

           SECTION 5.08. Pre-Closing Access to Information. From the date hereof
to the Closing Date, Seller will afford to the representatives of Purchaser,
including its counsel and auditors, during normal business hours, access to any
and all of the Business Assets and information with respect to the Storage
Products Business to the end that Purchaser may have a reasonable opportunity to
make such a full investigation of the Business Assets and the Storage Products
Business in advance of the Closing Date as it shall reasonably desire, and the
officers of Seller will confer with representatives of Purchaser and will
furnish to Purchaser, either orally or by means of such records, documents, and
memoranda as are available or reasonably capable of preparation, such
information as Purchaser may reasonably request, and Seller will furnish to
Purchaser's auditors all consents and authority that they may reasonably request
in connection with any such examination. In addition, Seller and Purchaser shall
cooperate on Tax information and record-keeping matters with regard to the
transition of the ownership of the Purchased Assets and the Storage Products
Business.

           SECTION 5.09. Taxes. Seller shall, to the extent that failure to do
so could adversely affect the Storage Products Business or the Business Assets,
(a) continue to file within the time period for filing all returns and reports
relating to Taxes, and such returns and reports shall be true, correct and
complete, and (b) pay when due any and all Taxes attributable to or levied or



                                       24
<PAGE>   25

imposed upon (i) the Business Assets used in the Storage Products Business for
periods (or portions thereof) through the Closing Date and (ii) the operations
of the Seller.

           SECTION 5.10.  Confidentiality.

           (a) Existing Agreement. The terms of the Mutual Confidential
Disclosure Agreement dated as of January 13, 1998 (the "EXISTING CONFIDENTIALITY
AGREEMENT") between Seller and Purchaser are hereby incorporated herein by
reference and shall continue in full force and effect until the Closing Date, at
which time the Existing Confidentiality Agreement shall terminate. If this
Agreement is terminated prior to the Closing for any reason then the Existing
Confidentiality Agreement shall continue in full force and effect.

           (b) Seller's Confidential Information. Excluding Acquired
Confidential Information (as defined below), all tangible manifestations of
confidential and/or proprietary information of Seller disclosed to Purchaser in
the course of negotiating the transaction contemplated by this Agreement
("SELLER'S CONFIDENTIAL INFORMATION") will be held in confidence and not
disclosed by Purchaser or any of its employees, affiliates or stockholders for a
period of five (5) years from the Closing Date and will be promptly destroyed by
Purchaser or returned to Seller, upon Seller's written request to Purchaser,
provided that Purchaser will not at any time use, or disclose to others, any
Licensed Technology Deliverables (in tangible form) for any purpose other than
the development of read channels and pre-amps for Storage Peripherals.
Purchaser's employees, affiliates and stockholders will not be given access to
Seller Confidential Information except on a "need to know" basis. It is agreed
that Purchaser Confidential Information will not include information that: (a)
is proven to have been known to Purchaser prior to receipt of such information
from the Seller; (b) is disclosed by a third party having the legal right to
disclose such information and who owes no obligation of confidence to the
Seller; (c) is now, or later becomes part of the general public knowledge or
literature in the art, other than as a result of a breach of this Agreement by
Purchaser; or (d) is independently developed by Purchaser without the use of any
Seller Confidential Information. Notwithstanding anything to the contrary,
Purchaser may use for any commercial purpose Confidential Information received
from Seller (whether or not such Confidential Information constitutes Purchased
Assets or Licensed Assets), provided that such Confidential Information is
Residual Information (as defined below) and provided that the right to use
Residual Information shall not be deemed a grant of rights under any patents or
copyrights of Seller. For purposes of this Agreement, "RESIDUAL INFORMATION"
means (i) information that has been remembered by Purchaser's consultants and
employees (including but not limited to employees that once were employed by
Seller) without referring to such information in a tangible form received from
Seller, and (ii) any tangible item created by a Purchaser employee or consultant
that may embody such information that has been remembered by such employee or
consultant without referring to such information in a tangible form received
from Seller. Purchaser shall not instruct its consultants or employees to
memorize Seller's Confidential Information so that it can be used as Residual
Information or can be disseminated for unauthorized use.

           (c) Purchaser's Confidential Information. All copies of financial
information, marketing and sales information, pricing, marketing plans, business
plans, financial and business projections, manufacturing processes and
procedures, formulae, methodologies, inventions, product designs, product
specifications and drawings, and other confidential and/or proprietary

                                       25
<PAGE>   26
information of Purchaser disclosed to Seller in the course of negotiating the
transaction contemplated by this Agreement ("PURCHASER CONFIDENTIAL
INFORMATION") will be held in confidence and not used or disclosed by Seller or
any of its employees, affiliates or stockholders for a period of five (5) years
from the Closing Date and will be promptly destroyed by Seller or returned to
Purchaser, upon Purchaser's written request to Seller. Seller's employees,
affiliates and stockholders will not be given access to Purchaser Confidential
Information except on a "need to know" basis. It is agreed that Purchaser
Confidential Information will not include information that: (a) is proven to
have been known to Seller prior to receipt of such information from the
Purchaser; (b) is disclosed by a third party having the legal right to disclose
such information and who owes no obligation of confidence to the Purchaser; (c)
is now, or later becomes part of the general public knowledge or literature in
the art, other than as a result of a breach of this Agreement by Seller; or (d)
is independently developed by Seller without the use of any Purchaser
Confidential Information.

           (d) Acquired Confidential Information. Except for marketing and sales
information which has been publicly disseminated to Seller's prospective
customers for the Storage Products Business prior to the Effective Date in the
ordinary course of business consistent with past business practice, all copies
of financial information, marketing and sales information, pricing, marketing
plans, business plans, financial and business projections, customer lists,
methodologies, inventions, software, know-how, product designs, product
specifications and drawings, and other confidential and/or proprietary
information which constitutes Purchased Assets (collectively, "ACQUIRED
CONFIDENTIAL INFORMATION") will be maintained by Seller in confidence at all
times after the Effective Date of this Agreement in the same manner and to the
same extent that Seller, acting reasonably, maintains Seller's Confidential
Information in confidence. At all times following the Closing, Seller will: (i)
continue to hold all Acquired Confidential Information in strict confidence,
(ii) will not use for itself or third parties any of Acquired Confidential
Information which constitutes or is constituted in Purchased Assets to any third
party, (iii) will not disclose to third parties any of Acquired Confidential
Information which constitutes or is constituted in Purchased Assets to any third
party, and (iv) upon Purchaser's or Sub's request, promptly destroy or deliver
to Purchaser and/or Sub any Acquired Confidential Information which constitutes
or is constituted in Purchased Assets in Seller's possession or control; except
that Seller may internally use the original copies of all Business Records
solely to prepare and file Tax returns and prepare Seller's financial
statements, and Seller may disclose any Acquired Confidential Information as may
be required to comply with requests from all governmental agencies, including
without limitation the SEC; provided that Seller must provide Purchaser with
prior written notice of any proposed disclosure to government agencies and with
respect to the SEC, an opportunity to seek confidential treatment of such
proposed disclosure. It is agreed that Acquired Confidential Information will
not include information that is now, or later becomes, part of the general
public knowledge or literature in the art, other than as a result of a breach of
this Agreement or the Existing Confidentiality Agreement by Seller.

           SECTION 5.11. No Other Bids. Until the earlier to occur of (a) the
Closing or (b) the termination of this Agreement pursuant to its terms, Seller
shall not, and Seller shall not authorize any of its officers, directors,
employees, agents or other representatives to, directly or indirectly, (i)
initiate, solicit or encourage (including by way of furnishing evaluation
material or other information regarding the Storage Products Business or the
Business Assets) any inquiries, 



                                       26
<PAGE>   27

or make any statements to third parties which may reasonably be expected to lead
to any proposal, concerning the sale of the Storage Products Business or all or
a portion of the Business Assets, or (ii) negotiate, engage in any substantive
discussions, or enter into any agreement, with any person concerning the sale of
the Storage Products Business or the Business Assets.

           SECTION 5.12. Public Announcements. On and prior to the Closing Date,
Purchaser and Seller shall advise and confer with each other prior to the
issuance of any reports, statements or releases concerning this Agreement
(including the exhibits hereto) and the transactions contemplated herein.
Neither Purchaser nor Seller will make any public disclosure prior to the
Closing or with respect to the Closing unless both parties agree on the text and
timing of such public disclosure, except as required by law. Nothing contained
in this Section shall prevent any party at any time from furnishing any
information pursuant to the requirements of any governmental entity.

           SECTION 5.13. Books and Records. If, in order properly to prepare
documents required to be filed with governmental authorities (including Tax
authorities) or its financial statements, it is necessary that any party hereto
or any successors be furnished with additional information relating to the
Business Assets, the Assumed Liabilities or the Storage Products Business, and
such information is in the possession of any other party hereto, such party
agrees to use its good faith efforts to promptly furnish such information to the
party needing such information, at the cost and expense of the party being
furnished such information. From and after the date of this Agreement and
continuing beyond the Closing, Seller shall cooperate with Purchaser and provide
to Purchaser at Purchaser's expense all financial information that may be
required to enable Purchaser to comply with all applicable laws, rules and
regulations, and any governmental filing requirements, whether imposed by the
Federal Trade Commission or otherwise, with respect to reporting and reflecting
the transactions contemplated by this Agreement.

           SECTION 5.14.  Regulatory and Other Authorizations; Consents.

           (a) Efforts. Each party hereto will use its reasonable best efforts
to obtain all authorizations, consents, orders and approvals of all United
States, Irish and other non-U.S., federal, state and local regulatory bodies and
officials that may be or become necessary for the execution and delivery of, and
the performance of its obligations pursuant to, this Agreement and the Ancillary
Agreements and will cooperate fully with the other party in promptly seeking to
obtain all such authorizations, consents, orders and approvals. Each party
hereto agrees to make an appropriate filing of a Notification and Report Form
pursuant to the HSR Act and the required filings under the Mergers Act with
respect to the transactions contemplated hereby as promptly as is practicable
after the date hereof and to supply promptly any additional information and
documentary material that may be requested by any governmental authority
pursuant to the HSR Act or the Mergers Act. The parties hereto will not take any
action that will have the effect of delaying, impairing or impeding the receipt
of any required approvals. Without limiting the generality of the parties'
undertakings pursuant to this Section, the parties shall use their reasonable
best efforts to prevent the entry in a judicial or administrative proceeding
brought under any antitrust law by any Government Antitrust Authority or any
other party of any permanent or preliminary injunction or other order that would
make consummation of the acquisition of the Business Assets in accordance with
the terms of this Agreement unlawful or that would prevent or delay such
consummation.

<PAGE>   28

           (b) Communications. Each party hereto shall promptly inform the other
of any material communication between such party and the Federal Trade
Commission, the Department of Justice or any other United States federal or
state, or non-U.S. government or governmental authority regarding any of the
transactions contemplated hereby. If any party or any affiliate of such party
receives a request for additional information or for documents or any material
from any such government or governmental authority with respect to the
transactions contemplated hereby, then such party shall endeavor in good faith
to make or cause to be made, as soon as reasonably practicable and after
consultation with the other party, an appropriate response in compliance with
such request. Further, no written materials shall be submitted by any party to
the Federal Trade Commission, the Department of Justice or any other United
States federal or state, or non-U.S. governmental agency in connection with HSR
Act compliance or the merger control or competition regulations of any other
country (including without limitation, the Mergers Act), nor shall any oral
communications be initiated with such governmental entities by any party,
without prior disclosure to and coordination with the other parties and their
counsel. Each party hereto will cooperate in connection with reaching any
understandings, undertakings or agreements (oral or written) involving the
Federal Trade Commission, the Department of Justice or any other United States
federal or state, or non-U.S. governmental authority in connection with the
transactions contemplated hereby.

           SECTION 5.15. Solvency . Seller is solvent and neither intends or
expects to file or seek relief under the United States Bankruptcy Code or any
other insolvency or similar law.

           SECTION 5.16. Further Actions. Each of the parties hereto shall, at
its own expense, execute and deliver such documents and other papers and take
such further actions as may be reasonably required to carry out the provisions
of this Agreement and the Ancillary Agreements and to give effect to the
transactions contemplated by this Agreement and the Ancillary Agreements. In the
event that any Subsidiary or affiliate of Seller owns or holds rights to any of
the Business Assets, Seller covenants and agrees to cause each such Subsidiary
or affiliate to take whatever action and execute whatever documents as are
necessary to implement this Agreement and the Ancillary Agreements.

           SECTION 5.17. Further Asset Transfer. From and after the date of the
Closing, Seller agrees to convey, transfer, and assign to Purchaser, free and
clear of all Encumbrances, any tangible or intangible rights, properties or
assets then held by the Seller the conveyance, transfer or assignment of which
would have been necessary for representations and warranties of the Seller
herein to be true and correct as of the date of the Closing, or the conveyance,
transfer or assignment of which was or is required by the covenants of the
Seller contained in this Agreement.

           SECTION 5.18. Technology and Patent License Agreement. At the
Closing, the Technology and Patent License Agreement, in substantially the form
of EXHIBIT A, shall be executed and delivered by Seller and Purchaser.

           SECTION 5.19. Non-Competition Agreement. Concurrently with the

           SECTION 5.20. Transfer of Assets. Seller shall take, or shall cause
its subsidiaries and affiliates to take, all action necessary to transfer all
right, title and interest in and to the Purchased Assets to Analog Devices, Inc.

United States Office of Export Administration, neither Seller nor Purchaser
shall knowingly export or reexport (including but not limited to delivery to a
foreign national) directly or indirectly any technical data received from the
other party, any technical data relating to the commodities received from the
other party or any immediate products (including processes and services)
produced directly by use of any of such technical data to any country to the
extent such export or reexport violates the Export Control Regulations of the
Bureau of International Commerce of the United States Department of Commerce.

           SECTION 5.22. Survival of Covenants. Each of the covenants set forth
in Sections 5.02(b), 5.02(c), 5.06, 5.07, 5.09, 5.10(b), 5.10(c), 5.10(d), 5.13,
5.16, 5.17, 5.20 and 5.21 shall survive the Closing. The covenants set forth in

                                   ARTICLE VI

                                EMPLOYEE MATTERS

           SECTION 6.01.  Right to Offer Employment.

           (a) Employees. SCHEDULE 13 contains a current list (the "PRELIMINARY
LIST") of each employee of Seller, of any of Seller's Subsidiaries or of any
other affiliates of Seller who works in, or provides services in connection
with, the Storage Products Business (each an "EMPLOYEE"). At least five (5) days
prior to the Closing Date, Seller shall update the list of the Employees (the
"FINAL LIST") and shall identify those Employees who are active Employees of the
Storage Products Business as of that date, including those on vacation, sick
leave, disability leave, family leave or personal leave of absence and which
shall separately identify those Employees who are on a workers'
compensation-related or disability leave. For purposes of this Article VI,
"EMPLOYEES" means only those individuals included on the Final List.

           (b) Offers of Employment. At Purchaser's request, Seller shall
cooperate with Purchaser in identifying those Employees that Purchaser may wish
to hire and in facilitating the employment by Purchaser, conditioned upon the
Closing, of those Employees (including any Employees who become such after the
Effective Date) whom Purchaser elects to employ. Prior to the Closing, Purchaser
shall have the right to contact such Employees at reasonable times and places
for the purpose of making offers of employment with Purchaser (in each case such
offers of employment shall be contingent on consummation of the transactions
contemplated by this Agreement). (Seller hereby expressly consents to offers of
employment being extended prior to or after the Effective Date.) Seller agrees
to use its best efforts to (i) retain Employees as employees of Seller through
the Closing Date, and (ii) assist Purchaser in securing the employment on the
Closing Date of those Employees to whom Purchaser (or an affiliate designated by
Purchaser) makes offers of employment; provided, however, that Seller shall not

compensation and benefits through the Closing Date, except as otherwise required
by this Agreement, and further provided that Seller shall not be restricted from
terminating any Employee for cause if Purchaser is advised a reasonable period
of time in advance of such action. Seller shall not transfer any Employee to
employment with Seller outside of the Storage Products Business prior to the
Closing without the consent of Purchaser. Seller shall notify Purchaser promptly
if any Employee terminates employment with Seller after the date of this
Agreement but prior to the Closing. Each such Employee who is employed by Seller
on the Closing Date and who actually accepts an offer of employment with
Purchaser (or any affiliate designated by Purchaser) effective as of or promptly
following the Closing Date as a result of an offer of employment made by
Purchaser is hereafter referred to as a "NEW HIRE". Seller will provide each New
Hire a period equal to the balance of the term of his or her option to exercise
any outstanding options to purchase Seller securities held by such New Hires and
shall as of the Closing Date vest all outstanding unvested options held by such
New Hire. Seller hereby consents to the hiring of such New Hires by Purchaser
and waives, with respect to the employment by Purchaser of such New Hires, any
claims or rights Seller may have against Purchaser with respect thereto and
against any such Employee under any non-competition, confidentiality or
employment agreement with respect to the Storage Products Business. Purchaser
shall not, however, be obligated to offer employment to any Employee and the
parties hereby acknowledge that Purchaser is under no obligation whatsoever to
employ any current or future employees of Seller or any of its affiliates. Such

workers' compensation-related or disability leave or a Family Medical Leave Act
leave or other statutory leave shall be conditioned upon their return from such
leave in accordance with Seller's leave of absence policy.

           (c) Employee Compensation. Purchaser shall be liable for and
obligated to pay and indemnify, and hold Seller and its affiliates harmless
from, any and all expenses, contracts, agreements, commitments, obligations,
claims, suits, and other liabilities of any nature whatsoever, whether known or
unknown, accrued or not accrued, fixed or contingent, or arising hereafter,
directly or indirectly, with respect to (i) the employment by Purchaser or
termination of employment by Purchaser of any current or future employee or
consultant of Purchaser or any of its affiliates, including without limitation,
the employment or termination of a New Hire after the Closing Date, whether in
connection with the transactions contemplated hereby or otherwise; (ii) any
claims of discrimination under state or federal law provided such claims arise
from the New Hire's employment or service with or termination by Purchaser after
the Closing Date; (iii) any other claims or obligations arising out of the terms
and conditions of employment of any person by Purchaser whether for salary,
wages, bonuses, profit sharing, commissions, severance, vacation pay, sick pay
or otherwise; (iv) any duties or obligations of Purchaser or administrators
under any existing or future employee benefit plans or arrangements maintained
by Purchaser with respect to its employees; or (v) any present or future
obligations or liabilities of Purchaser to prior, existing or future employees
of Purchaser.

           SECTION 6.02. Employment Taxes. Seller shall be responsible for any
withholding or employment Taxes with respect to any Employees which accrue or
become payable during the period of such Employee's employment or service with

responsible for filing all United States and non-U.S. federal, state and local
employment

Tax returns with respect to such Employees attributable to periods of employment
or service with Seller or any affiliate of Seller.

           SECTION 6.03. Termination of Employment. Seller agrees to comply with
the provisions of the Undertakings Law and any other United States or non-U.S.
federal, state or local statute or regulation regarding termination of
employment, plant closing or layoffs and to perform all obligations required by
Seller with respect to the cessation of any operations of the Storage Products
Business or any other business of Seller or reductions in workforce or the
termination, re-assignment, re-location or change in position of any Employee
(or other employee of Seller or of any of Seller's Subsidiaries or any other
affiliate of Seller) prior to, on or after the Closing Date. Seller shall
indemnify and hold Purchaser and Sub harmless with respect to any liability
under the Undertakings Law or other applicable United States or non-U.S.
federal, state or local statute or regulation affecting termination of
employment arising in connection with the transactions contemplated by this
Agreement.

           SECTION 6.04. No Employment Obligations Assumed; Vesting. Without
limiting Sections 3.13 and 3.14, Seller shall be liable for and obligated to pay
and indemnify and hold Purchaser and its affiliates harmless from any and all
expenses, contracts, agreements, commitments, obligations, claims, suits, and
other Liabilities of any nature whatsoever, whether known or unknown, accrued or
not accrued, fixed or contingent or arising hereafter, directly or indirectly,
with respect to (i) any of Seller's obligations under this Article VI; (ii) the
employment or termination of employment by Seller of any current or future
employee or consultant of Seller or any of its affiliates, including without

contemplated hereby or otherwise; (iii) any claims of discrimination under
United States or non-U.S., federal, state or local law provided such claims
arise from such Employee's employment or service with or termination by Seller;
(iv) any other claims or obligations arising out of the terms and conditions of
employment (including under any Seller agreement), whether for salary, wages,
bonuses, profit sharing, commissions, severance, vacation pay, sick pay or

Seller or administrators under any existing or future employee benefit plans of
Seller or any of its affiliates; or (vi) any present or future Liabilities of
Seller or any of its affiliates to prior, existing or future employees of Seller
or any of its affiliates, whether or not specifically described in this Article
VI. Seller shall pay to all terminated Employees, including New Hires, any
Liability for accrued vacation, sick leave or similar benefits with respect to
such Employees attributable to periods of employment or service with Seller,
consistent with Seller's policies and applicable law, and shall make such
payment within the statutory time period therefor but in no event later than
five days after such Employee's employment with Seller is terminated. As of the
Hire Date of each New Hire, Seller shall fully vest such New Hire under all
applicable qualified and non-qualified plans of Seller. Purchaser shall be
responsible for any Liability for any employment contract or employment
contractual obligations to New Hires entered into by Purchaser. Purchaser shall
be responsible for any Liability with respect to any claims of discrimination
under United States, non-U.S. federal, state or local law arising on or after a
New Hire's Hire Date.

<PAGE>   32

           SECTION 6.06. Non-U.S. Employees. Without limiting any other
provision hereof, Seller acknowledges and agrees that if Purchaser elects to
offer employment to some but not all Employees located in particular non-U.S.
jurisdictions, or if requisite notice prior to the Effective Date or the Closing
Date is not given to certain non-U.S. Employees or non-U.S. governmental
agencies regarding possible employment transitions to Purchaser of certain
Employees, certain non-U.S. laws, rules or regulations may be violated or may
not be complied with, possibly resulting in Liability, possibly including
without limitation a need to pay or accrue severance, a need for Seller to
continue employing non-U.S. Employees for some mandated period, a need for
Purchaser or a Purchaser Subsidiary to commence employing non-U.S. Employees
that Purchaser does not wish to employ ("MANDATED EMPLOYEES"), a need for
Purchaser to pay salary to Mandated Employees and then severance to them upon
terminating them as soon as legally permissible, an obligation of Purchaser to
honor non-U.S. Employees' pension obligations, and fines, sanctions and
penalties imposed on Seller or Purchaser or related parties and related
Liabilities with respect thereto and Liabilities associated with claims brought
against Seller or Purchaser or related parties by non-U.S. Employees or non-U.S.
governmental agencies or Mandated Employees with respect to any of the foregoing
(collectively, "FOREIGN EMPLOYEE LIABILITIES"). Nevertheless, without limiting
any other provision hereof, Seller agrees to indemnify, hold harmless and defend
Purchaser from and against any and all such Foreign Employee Liabilities,
including without limitation those arising under the Undertakings Law, and to
take all actions required to avoid (where possible) or minimize such Foreign
Employee Liabilities, including without limitation, paying or accruing severance
or other amounts and giving all notices and obtaining all approvals and paying
all fines required to do so, without regard to the limitations on
indemnification provided in Article IX hereof. Purchaser agrees to exercise
commercially reasonable efforts to minimize Foreign Employee Liabilities, but
shall have no liability for failing to do so and no actual or alleged failure to
do so shall relieve Seller from any of Seller's obligations or Liabilities under
this Section.

           SECTION 6.07.  General Matters.

           (a) Compensation Program. Purchaser and Seller shall work together to
provide an incentive program for Employees to whom Purchaser offers employment
to accept such offers. Purchaser shall, among other things, grant options to
purchase shares of Purchaser's stock to New Hires, pay a joining bonus to each
New Hire, pay the reasonable costs of relocation of New Hires and his/her family
to the location selected by Purchaser, and enroll the New Hire in Purchaser's
standard employee benefit programs, subject to Purchaser's standard policies
applicable thereto.

           (b) Immigration, Visas. Purchaser shall be responsible for obtaining
any required visas or other immigration approvals to allow New Hires to become

employment with Seller or any affiliate of Seller, whether occurring prior to or
following the Closing Date and whether arising pursuant to the Undertakings Law
or otherwise. Seller shall defend and indemnify Purchaser and Sub and hold
Purchaser and Sub 



                                       32
<PAGE>   33

harmless from and against all Liabilities to Purchaser or Sub to the extent that
the same arise as a result of any Employee's alleging that the acquisition of
the Business Assets hereunder and the hiring (or non-hiring) of Employees by
Purchaser on the Closing Date constitutes a termination entitling such Employee
to severance or any similar benefit or right pursuant to a plan maintained by
Seller or pursuant to applicable statutes. Notwithstanding anything to the
contrary herein, there shall be no monetary or time limitation or "basket" on
Seller's liability to Purchaser and Sub in Article IX hereof or elsewhere under
this Section 6.07(c).

           (d) No Terminations. Seller covenants and agrees that it will not
terminate any Employee or Consultant who does not become a New Hire and that

pursuant to that certain R&D Services and Transition Support Agreement (as
defined in Section 8.01(e) below) to be entered into by Seller and Purchaser at
the Closing and that Seller presently intends to reassign (in a manner that
would not constitute a constructive termination under applicable law) each such
Employee and Consultant within Seller's organization at the expiration of the
R&D Services and Transition Support Agreement.

           SECTION 6.08. No Solicitation. Except as provided by law, for a
period of one (1) year after the Closing Date, without Purchaser's written
permission, Seller shall not hire or employ any New Hire, and for a period of
three (3) years after the Closing Date, without Purchaser's written permission,
Seller shall not actively solicit any New Hire to terminate his or her
employment with Purchaser or to become an employee of Seller. Except as provided
by law, for a period of one (1) year after the Closing Date, without Seller's
written permission, Purchaser shall not hire or employ any employee of Seller
assigned to work on the R&D Services and Transition Support Agreement ("R&D
EMPLOYEE"), and for a period of three (3) years after the Closing Date,
Purchaser shall not actively solicit any R&D Employee to terminate his or her
employment with Seller or to become an employee of Purchaser, without the prior
written consent of Seller. For purposes of this Section, the term "actively
solicit" shall not mean or include the placement of advertisements,
participation in career days, utilizing headhunters or placement agencies or
responding to unsolicited inquiries, applications or resumes.

           SECTION 6.09. No Rights Conferred Upon Employees. Nothing in this
Article VI or any other provision of this Agreement shall confer any rights or
remedies on any employee (including without limitation any Employee, New Hire or
R&D Employee) and no employee (including without limitation any Employee, New
Hire or R&D Employee) shall be a third party beneficiary with respect to any

the amount of Seller's liability with respect to its indemnification obligations
under Section 7.01 or on Seller or Purchaser or Sub's liability with respect to
their respective indemnification obligations under Section 7.02 hereof, and
Seller, Purchaser, Sub or their successors and assigns may assert any such
indemnity claim at any time prior to expiration of the applicable legal statute
of limitations applicable to the subject matter of the claim underlying the
claim for indemnification under applicable law.

           SECTION 7.04. Treatment of Indemnity Payments. All payments made by
Seller or Purchaser, as the case may be, to or for the benefit of the other
party pursuant to any indemnification obligations under this Agreement shall be
treated as adjustments to the Purchase Price for Tax purposes and such agreed
treatment shall govern for purposes of this Agreement, unless otherwise required
by law.

hold Purchaser, Sub and each of the other Purchaser Indemnitees harmless from,
all Loss arising out of, resulting from, caused by or attributable to:

           (a) the failure of any representation or warranty of Seller contained

representation or warranty contained in the Ancillary Agreements or the Seller
Closing Documents to be true and correct as of the Closing Date;

charges or actions brought by employees, agents or representatives of Seller
arising out of or based upon events occurring on or prior to the Closing Date;

           (e) Liability for (or any Liability applicable to Purchaser, Sub or
any other Purchaser Indemnitee as a result of) noncompliance with any bulk
sales, bulk transfer, fraudulent conveyance or similar laws applicable to the
transactions contemplated by this Agreement or any claim asserting that any
transactions contemplated by this Agreement constitutes a fraudulent conveyance
or any similar claim;

           (f) any demand, claim, debt, suit, cause of action, arbitration or
other proceeding that is made or asserted by any third party arising out of any
product or service that was sold, licensed or otherwise provided by Seller to
third parties (either prior to, on or after the Closing);

           (g) any demand, claim, debt, suit, cause of action, arbitration or
other proceeding made or asserted against Purchaser arising because of the

former employee or independent contractor of Seller, any Seller Subsidiary or
any affiliate of Seller, that relates in any manner to any alleged, actual or
constructive termination by Seller, any Seller Subsidiary or any affiliate of
Seller of such person's employment or the services of such person, or that
involves a claim of adverse employment action, discrimination, relocation,
promotion, demotion, unequal pay or any other matter relating to the employment
of such person by Seller, any Seller Subsidiary or any affiliate of Seller;

           (i) termination by Seller, any Seller Subsidiary or any affiliate of

after the Closing Date, severance 



                                       39
<PAGE>   40

benefits related to any Employee's termination of employment with Seller, any
Seller Subsidiary or any Seller affiliate, and any failure by Seller, any Seller
Subsidiary or any Seller affiliate to pay or withhold any Taxes payable with
respect to the employment by Seller, any Seller Subsidiary or any Seller
affiliate of any Employee or any failure by Purchaser to hire such Employee;

           (j) any Transaction Taxes payable on or with respect to the purchase,

           SECTION 9.03 Infringement Indemnification by Seller.

           (a) Indemnity Obligation. Subject to Section 9.06, Seller agrees to
indemnify Purchaser, Sub and each of the other Purchaser Indemnitees against,
and to hold Purchaser, Sub and each of the other Purchaser Indemnitees harmless
from, all Losses not exceeding the "Maximum Amount" (as defined below) that are
payable to third parties arising out of, resulting from, caused by or
attributable to any violation or infringement by the Products or the use of any
Business Assets in the manner used by Seller prior to the Closing, of any
copyright, mask work, trade secret, or other intellectual property or related
right of any third party other than trademarks, but excluding any violation or
infringement primarily based on (i) a modification of the Products or other
Business Assets, other than a modification provided by Seller, if the violation
or infringement would not have occurred but for the particular modification,
(ii) a combination, other than a combination provided by Seller, of the
Products, or components or elements of a Product, with other products,
components, elements or technologies not provided by Seller, if the violation or
infringement would not have resulted but for the particular combination, or
(iii) which would not have resulted but for Purchaser's failure to implement a
"Design Around" (as defined in that certain Design Letter, dated of even date
herewith between Seller and Purchaser). "MAXIMUM AMOUNT" shall mean (A) the
lesser of (1) Twenty Million Dollars ($20,000,000), less any amounts previously
paid by Seller under Section 9.02, and (2) the total amount of all royalties
paid or accrued for payment, or later accrued for payment under the Technology
and Patent License Agreement, both before and after a Claim is made, (B) less
any amounts previously paid by Seller to Purchaser under this Section 9.03. For
clarification, the aggregate Maximum Amount payable under this Section 9.03
shall in no event exceed the amount of all royalties paid or accrued for
payment, or later accrued for payment under the Technology and Patent License
Agreement, both before and after a Claim is made.



                                       40
<PAGE>   41

           (b) Infringed Patent Licenses. Upon the occurrence of a "Patent
Indemnity Event" (defined below), Seller shall use diligent efforts, not to
exceed commercially reasonable efforts, to obtain for Purchaser, at Seller's
sole cost and expense not to exceed the Maximum Amount, a license ("3RD PARTY
LICENSE") from the third party owner of any patent ("PATENT OWNER") that is the
subject of the Patent Indemnity Event, granting Purchaser and its affiliates the
right to manufacture, have manufactured, use, sell and import read channel and
magneto resistive preamp Products for Storage Peripherals, and to grant
sublicenses of any such rights. For purposes of this Agreement, "PATENT
INDEMNITY EVENT" means the occurrence of any of the following events (including
any combination of events):

                     (i)    A written claim of patent infringement by a Product
                            is received from a third party and Purchaser's
                            patent counsel determines that the claim is valid
                            ("TYPE A INDEMNITY EVENT"); or

                     (ii)   A claim for injunctive relief has been sought
                            against Purchaser, and Purchaser's patent counsel
                            determines that injunctive relief is likely to be
                            granted to a third party due to patent infringement
                            by a Product ("TYPE B INDEMNITY EVENT"); or

                     (iii)  Injunctive relief due to a claim for patent
                            infringement by a Product is granted to a third
                            party ("TYPE C INDEMNITY EVENT").

           If for any reason Purchaser does not obtain the 3rd Party License by
the "Required License Date" (as defined below), then, at Purchaser's option,
Purchaser may obtain the 3rd Party License directly from the Patent Owner and
receive, promptly upon request to Seller, reimbursement ("FEE REIMBURSEMENT")
from Seller. However, the aggregate Fee Reimbursement from all Patent Owners
shall not exceed the Maximum Amount, nor shall the Fee Reimbursement include
amounts, if any, paid to the Patent Owner for license rights in respect of
intellectual property not infringed by the Products. If the 3rd Party License
covers any such additional license rights, then the Fee Reimbursement shall be
calculated as a fraction of the total 3rd Party License fees. Such fraction
shall correspond to the proportional economic value of the intellectual property
that is infringed by the Products (as compared to all intellectual property
rights granted under the 3rd Party License). Purchaser may offset royalties
under the Technology and Patent License Agreement against Fee Reimbursement
amounts not yet received by Purchaser. "REQUIRED LICENSE DATE" means the date
that the 3rd Party License is required, calculated as the earliest of (a) ninety
(90) days after a Type A Indemnity Event, (b) sixty (60) days after a Type B
Indemnity Event, and (c) thirty (30) days after a Type C Indemnity Event.

           (c) Design Around Abandonment. Seller shall have no indemnity
obligation under Section 9.03(a) above for any violation or infringement
referred to in that certain Design Letter if Purchaser has instructed engineers
performing work on the Design Arounds pursuant to the R&D Services and
Transition Support Agreement to abandon development ("ABANDONMENT INSTRUCTION")
of applicable Design Arounds and the Design Arounds, if implemented by
Purchaser, would have avoided the violation or infringement. An assignment of
one or more engineers to particular tasks of relatively short duration (measured
in terms of days) not related to Design Arounds development, or to perform a
function that can be performed 



                                       41
<PAGE>   42

contemporaneously with such engineer's Design Arounds development activities,
will not be deemed to be an Abandonment Instruction.

           (d) .6 Micron and .35 Micron Product Patent Limitation. Seller shall
have no indemnity obligation under Section 9.03(a) above for any patent
violation or infringement that arises with respect to any product that is not a
 .6 micron or .35 micron product if the corresponding .6 micron and .35 micron
Products do not violate or infringe such patent.

           SECTION 9.04. Indemnification by Purchaser. Purchaser agrees, subject
to the other terms, conditions and limitations of this Agreement (including the
provisions of Section 9.06 hereof), to indemnify Seller and each of the other
Seller Indemnitees against, and to hold Seller and each of the other Seller
Indemnitees harmless from, all Loss arising out of, resulting from, caused by or
attributable to:

           (a) the failure of any representation or warranty of Purchaser
contained in this Agreement (including any schedule or exhibit hereto), to be
true and correct as of the Effective Date or as of the Closing Date or the
failure of any representation or warranty contained in the Ancillary Agreements
or the Purchaser Closing Documents to be true and correct as of the Closing
Date;

           (b) the breach or violation by Purchaser of any covenant or agreement
of Purchaser contained in this Agreement (including any schedule or exhibit
hereto), the Ancillary Agreements or the Purchaser Closing Documents;

           (c) the operation of the Storage Products Business by Purchaser after
the Closing Date;

           (d) any demand, claim, debt, suit, cause of action, arbitration or
other proceeding (including, but not limited to, a warranty claim, a strict
product liability claim or any other claim) that is made or asserted by any
third party that relates to any product defects, including latent defects, of
any product or service, including any of the Products, provided by Purchaser to
any customer after Closing unless such Products are produced after the Closing
Date and contain a design defect based on unmodified designs transferred as part
of the Business Assets; and

           (e) any demand, claim, debt, suit, cause of action or proceeding made
or asserted by any employee or independent contractor or any former employee or
independent contractor of Purchaser, that relates in any manner to any
termination after the Closing Date by Purchaser of a New Hire or any other
matter relating to Purchaser's employment of a New Hire after the Closing Date;

provided however, that nothing in this Section 9.04 shall impose on Purchaser
any duty to indemnify Seller for any Excluded Liabilities.

           SECTION 9.05.  Procedures for Indemnification.

           (a) As used herein, an "INDEMNIFIED PARTY" means a Purchaser
Indemnitee seeking indemnification pursuant to Section 9.02 or Section 9.03
hereof or a Seller Indemnitee seeking indemnification pursuant to Section 9.04
hereof. The Indemnified Party agrees to give the other 



                                       42
<PAGE>   43

party ("INDEMNITOR") prompt written notice of any event, or any claim, action,
suit, demand, assessment, investigation, arbitration or other proceeding by or
in respect of a third party (a "THIRD PARTY CLAIM") of which it has knowledge,
for which such Indemnified Party is entitled to indemnification under this
Article IX (including in any case copies of any summons, complaint or other
pleading which may have been served on it and any written claim, demand,
invoice, billing or other document evidencing or asserting the same). No delay
on the part of an Indemnified Party in giving the Indemnitor notice of a Third
Party Claim shall relieve the Indemnitor from any obligation hereunder unless
(and then solely to the extent) that the Indemnitor is prejudiced thereby.

           (b) The Indemnitor will have the right, at its sole cost and expense,
to defend the Indemnified Party against the Third Party Claim with counsel of
the Indemnitor's choice that is reasonably satisfactory to the Indemnified Party
so long as (i) the Indemnitor notifies the Indemnified Party in writing within
ten (10) days after the Indemnified Party has given notice of the Third Party
Claim that the Indemnitor intends to undertake such defense, (ii) the Indemnitor
provides each Indemnified Party with evidence reasonably acceptable to the
Indemnified Party that the Indemnitor will have the financial resources to
defend against the Third Party Claim and fulfill its Indemnification obligations
hereunder, (iii) the Third Party Claim involves only money damages and does not
seek an injunction or other equitable relief, (iv) settlement of, or an adverse
judgment with respect to, the Third Party Claim is not, in the good faith
judgment of the Indemnified Party, likely to establish a precedential custom or
practice materially adverse to the continuing business interests of the
Indemnified Party, (v) the Indemnitor conducts the defense of the Third Party
Claim actively and diligently; and (vi) the counsel chosen by the Indemnitor
does not have any conflict of interest in representing the interests of the
Indemnified Party.

           (c) So long as the Indemnitor is conducting the defense of the Third
Party Claim in accordance with Section 9.05(b) above, (i) the Indemnified Party
may retain separate co-counsel and participate in the defense of the Third Party
Claim at its own cost and expense (except as provided below) and shall have the
right to receive copies of all pleadings, notices and communications with
respect to the Third Party Claim to the extent no privilege is thereby waived,
(ii) the Indemnified Party may participate in settlement negotiations with
respect to the Third Party Claim, and (iii) the Indemnitor will not consent to
the entry of any judgment or enter into any settlement with respect to the Third
Party Claim unless (A) each affected Indemnified Party consents thereto in
writing (which consent will not unreasonably be withheld) or (B) the settlement,
compromise or consent includes an unconditional release from all Liability with
respect to the claim in favor of each affected Indemnified Party.
Notwithstanding the foregoing, if an Indemnified Party is offered a written
settlement proposal by a third party that has as its sole component the payment
of money by the Indemnified Party and the Indemnitor recommends to the
Indemnified Parties in writing that they accept such settlement proposal (the
"SANCTIONED SETTLEMENT") and the Indemnified Parties refuse to accept such
settlement proposal, in such event if the ultimate settlement terms agreed to by
the Indemnified Party with such third party or the final monetary damages award
against the Indemnified Parties after exhaustion of all appeals either referred
to as (the "FINAL SETTLEMENT AMOUNT"), is greater than the amount of the
Sanctioned Settlement, the Indemnified Party shall be responsible for the
differential between the Final Settlement Amount and the Sanctioned Settlement
and the Indemnitor's liability shall be limited to the amount specified in the
Sanctioned Settlement.



                                       43
<PAGE>   44

           (d) If the Indemnitor does not elect to assume control of or
otherwise participate in the defense or settlement of any Third Party Claim, or
if the Indemnitor does so elect but any of the conditions in Section 9.05(b)
above is or becomes unsatisfied, or if the Indemnitor ceases to any time to
actively defend the Third Party Claim, then, (i) the Indemnified Party may
defend against and consent to the entry of any judgment or enter into any
settlement with respect to the Third Party Claim, provided, however, that the
Indemnitor (A) shall have the right to receive copies of all pleadings, notices
and communications with respect to the Third Party Claim so long as the receipt
of such documents by the Indemnitor does not affect any attorney-client
privilege relating to the Indemnified Party, and (B) may participate in
settlement negotiations with respect to the Third Party Claim and the
Indemnified Party shall not enter into any settlement without the prior written
consent of the Indemnitor (which consent shall not be unreasonably withheld),
(ii) the Indemnitor will reimburse the Indemnified Party promptly and
periodically for all costs and expenses incurred in defending against the Third
Party Claim (including without limitation reasonable attorneys' and experts'
fees and expenses and court and arbitration costs), and (iii) the Indemnitor
will remain responsible for any Loss the Indemnified Party may suffer resulting
from, arising out of, relating to or caused by the Third Party Claim to the
fullest extent provided in this Article IX.

           SECTION 9.06.  Limitations on Indemnification.

           (a) Limits on Seller Indemnification. Seller's liability to indemnify
Purchaser and other Indemnified Parties for Loss under this Article IX shall not
be subject to any limitation except as set forth below in clauses (i) and (ii)
of this Section 9.06(a) or except as set forth in Section 9.03 with respect to
infringement indemnification:

                     (i) Seller shall not be required to provide indemnification
under this Article IX unless and until the aggregate Loss for which one or more
Purchaser Indemnitees seeks indemnification hereunder exceeds an aggregate of
Two Hundred Fifty Thousand Dollars ($250,000) (the "SELLER BASKET"), in which
event Seller shall be liable to indemnify the Purchaser Indemnitees for all
Loss, including any Loss within the Seller Basket.

                     (ii) The maximum aggregate Loss recoverable by Purchaser
Indemnitees (considered together as a group) against Seller under this Article
IX shall not exceed Twenty Million Dollars ($20,000,000) (the "SELLER CAP").

           Notwithstanding the foregoing, Purchaser and any other Indemnified
Party shall be entitled to recover any Loss arising from (i) fraud or willful
misconduct on the part of Seller, (ii) the failure of any representation or
warranty of Seller contained in Article VII to be true and correct as of the
Closing or (iii) the rescission of or injunction against any transaction
contemplated by this Agreement, in each case regardless of the Seller Basket
and/or the Seller Cap provisions contained in this Section 9.06(a).

           (b) Limits on Purchaser Indemnification. Purchaser's liability to
indemnify Seller Indemnitees for Loss under Section 9.04 shall be subject to the
limitations as set forth below in clauses (i) and (ii):



                                       44
<PAGE>   45

                     (i) Purchaser shall not be required to provide
indemnification under this Article IX unless and until the aggregate Loss for
which one or more Seller Indemnitees seeks indemnification hereunder exceeds an
aggregate of Two Hundred Fifty Thousand Dollars ($250,000) (the "PURCHASER
BASKET"), in which event Purchaser shall be liable to indemnify the Seller
Indemnitees for all Loss, including any Loss within the Purchaser Basket.

                     (ii) The maximum aggregate Loss recoverable by Seller
Indemnitees (considered together as a group) against Purchaser under this
Article IX shall not exceed Five Million Dollars ($5,000,000) (the "PURCHASER
CAP").

           The Purchaser Basket and Purchaser Cap shall not apply to the failure
by Purchaser to pay Seller the Development Fee or the consideration specified in
Section 4 of the Technology and Patent License Agreement; provided, however,
that the foregoing shall not prevent Purchaser from exercising the set off
rights provided in Section 9.07.

           (c) Time Limits. Notwithstanding anything herein to the contrary, no
claim for indemnification under this Article IX may be brought after the third
(3rd) anniversary of the Closing Date; provided, however, that with respect to
the representations and warranties of Seller contained in Sections 3.07, 3.17
and 3.19 of this Agreement and with respect to claims pursuant to the
intellectual property indemnity provided in Section 9.03 above, a claim for
indemnification under this Article IX may be brought until the fifth (5th)
anniversary of the Closing Date or the end of the statutory period, whichever is
longer. To preserve a claim for indemnification under this Article IX, an
Indemnified Party need only provide written notice in reasonable detail of such
claim to the Indemnitor prior to the expiration of the applicable time limit (if
any) described in the preceding sentence; and if an Indemnified Party provides
such notice prior to the expiration of such time limit, such Indemnified Party
may pursue such claim for indemnification after the expiration of such time
limit.

           SECTION 9.07. Setoff Rights. In addition to its foregoing rights
under this Article IX, Purchaser and Sub may offset the amount of any Loss for
which Purchaser and Sub are entitled to indemnification under this Article IX as
a credit against Purchaser's and Sub's obligations under Article II hereof to
pay Seller the Development Fee and to pay Seller amounts payable pursuant to any
of the Ancillary Agreements, and Purchaser and Sub may effect such offset by
withholding payment to Seller of the applicable amount from the Development Fee
and/or from amounts payable to Seller pursuant to the Ancillary Agreements.
- -Purchaser and Sub may set off a Loss under the preceding sentence even if the
Basket is not yet exceeded. Purchaser shall give Seller written notice of its
intent to withhold and set off any part of the Development Fee or amounts
payable pursuant to the Ancillary Agreements and an opportunity for fifteen (15)
days to object thereto in writing, provided that the basis of the objection is
specified in detail. To ensure that Purchaser and Sub will be able to exercise
its rights under this Section 9.07, Seller shall not, directly or indirectly,
assign or transfer to any other person any right to receive any portion of the
Development Fee or the amounts payable pursuant to the Ancillary Agreements.

           SECTION 9.08. No Limitation on Other Rights or Injunctive Relief. The
foregoing provisions of Article IX, together with the other specific
indemnifications and allocations of liability specified in other Sections or
Articles of this Agreement and/or the Ancillary Agreements, are the sole remedy
of an Indemnified Party for a breach of a representation, 



                                       45
<PAGE>   46

warranty, covenant or agreement of the other party contained in this Agreement;
provided, however, that nothing herein shall be deemed to restrict a party's
ability to seek and obtain injunctive relief.

                                    ARTICLE X

                        TERMINATION, AMENDMENT AND WAIVER

           SECTION 10.01. Termination. This Agreement may be terminated at any
time prior to the Closing:

           (a) by the mutual written consent of Seller and Purchaser; or

           (b) by either Purchaser or Seller at any time prior to Closing, if
the other commits a material breach of this Agreement that is not cured within
ten (10) days after notice thereof; or

           (c) by either Seller or Purchaser, if the Closing shall not have
occurred prior to May 2, 1998; provided, however, that the right to terminate
this Agreement under this Section 10.01(c) shall not be available to any party
whose failure to fulfill any obligation under this Agreement shall have been the
cause of, or shall have resulted in, the failure of the Closing to occur prior
to such date; or

           (d) by either Seller or Purchaser if there shall have been
instituted, pending or threatened (and not withdrawn) any action or proceeding
by any governmental authority or administrative agency before any governmental
authority, administrative agency or court of competent jurisdiction, or there
shall be in effect any judgment, decree or order of any governmental authority,
administrative agency or court of competent jurisdiction, in either case,
seeking to prevent consummation of any of the transactions contemplated by this
Agreement or the Ancillary Agreements, or seeking to prohibit or limit Purchaser
or any of its subsidiaries from exercising all material rights and privileges
pertaining to the Business Assets or the ownership, use or operation by
Purchaser or any of its subsidiaries of all or a material portion of the
Business Assets, or seeking to compel Purchaser or any of its subsidiaries to
dispose of or hold separate all or any material portion of the Business Assets.

           SECTION 10.02. Effect of Termination. In the event of termination of
this Agreement as provided in Section 10.01, this Agreement shall forthwith
become void (excepting only those provisions hereof that by their terms survive
the termination of this Agreement) and there shall be no liability on the part
of any party hereto; provided that nothing herein shall relieve either party
from liability for any willful breach hereof.

           SECTION 10.03. Waiver. At any time prior to the Closing, any party
hereto may (a) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto, or (c) waive compliance with any of the agreements or
conditions contained herein. Any such extension or waiver shall be valid if set
forth in an instrument in writing signed by the party to be bound thereby.

                                   ARTICLE XI

                               DISPUTE RESOLUTION

           SECTION 11.01.  Management Negotiation.

           (a) Purchaser and Seller shall attempt to resolve disputes between
the Purchaser and the Seller arising out of or in connection with this Agreement
through good faith negotiations as provided herein. The parties agree that
disputes shall be fully discussed by the functional representatives of Purchaser
and the Seller involved in the dispute in an attempt to achieve a prompt
resolution of such dispute. In the event that such dispute shall not be promptly
resolved by the mutual agreement of the functional representatives of Purchaser
and Seller, the dispute shall be submitted to senior management representatives
of each of Purchaser and Seller. Such senior management representatives of
Purchaser and Seller shall meet and fully discuss such dispute in an attempt to
achieve a prompt resolution of the dispute. If such dispute is not promptly
resolved by the mutual agreement of such senior management representatives of
Purchaser and Seller, each of Purchaser and Seller shall be free to exercise any
of the remedies available to it (i) pursuant to the terms of this Agreement or
(ii) otherwise at law or in equity.

           (b) Purchaser and Seller acknowledge that, from time to time, certain
material disputes arising out of or in connection with this Agreement may
objectively require immediate resolution. Accordingly, any such dispute may, at
the option of either the Purchaser or the Seller, be processed through an
abbreviated mediation process. Such abbreviated mediation process shall entail
submitting any such dispute to the senior management representatives of each of

a prompt and expeditious resolution. In the event that a prompt and expeditious
resolution of such dispute is not achieved through the mutual agreement of such
senior management representatives of the Purchaser and the Seller, each of
Purchaser and Seller shall be free to exercise any of the remedies available to
it (i) pursuant to the terms of this Agreement or (ii) otherwise at law or in
equity.

           (c) Each of Purchaser and Seller agrees to act reasonably and in good
faith in connection with all matters arising out of or in connection with this
Agreement that are submitted to the mediation process set forth in this Article
XI.

           SECTION 11.02. Waiver of Jury Trial. The parties hereby waive trial
by jury in any litigation in any court with respect to, in connection with, or
arising out of this Agreement, the Ancillary Agreements or the transactions
contemplated thereby.

           SECTION 12.05. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in a mutually acceptable
manner in order that the transactions contemplated hereby be consummated as
originally contemplated to the greatest extent possible.

           SECTION 12.06. Entire Agreement. This Agreement, the Ancillary
Agreements and the Purchase Price Allocation Agreement constitute the entire
agreement and understanding of the parties hereto with respect to the subject
matter hereof and supersede all prior agreements and undertakings with respect
to the subject matter hereof, both written and oral. Upon the effectiveness of
the Closing, the Existing Confidentiality Agreement shall terminate.

           SECTION 12.07. Assignment. This Agreement shall not be assigned by
Purchaser or Seller without the prior written consent of the non-assigning
party; provided, however, that Purchaser and/or Sub may assign all or a portion
of its rights and obligations hereunder to one or more wholly-owned subsidiaries
or affiliates of Purchaser.

           SECTION 12.08. No Third-Party Beneficiaries. This Agreement is for
the sole benefit of the parties hereto and their permitted assigns and nothing
herein, express or implied, is intended to or shall confer upon any other person
or entity any legal or equitable right, benefit or remedy of any nature
whatsoever under or by reason of this Agreement.

           SECTION 12.09. Amendment; Waiver. This Agreement may not be amended
or modified except by an instrument in writing signed by Seller and Purchaser
(which instrument will bind Sub). Waiver of any term or condition of this
Agreement shall only be effective if in writing and shall not be construed as a
waiver of any subsequent breach or waiver of the same term or condition, or a
waiver of any other term or condition of this Agreement.

           SECTION 12.10. Governing Law; Jurisdiction and Venue. This Agreement
shall be governed by, and construed in accordance with, the internal laws of the
State of California applicable to contracts executed in and to be performed by
residents of California within that State. Seller consents to submit to the
jurisdiction of any federal or state court located in the State of California
and agrees not to object to venue in the federal or state courts located in
Santa Clara County, California. The provisions of the U.N. Convention on
Contracts for the International Sale of Goods shall not apply to this Agreement.

           SECTION 12.11. Construction of "Seller". Except as the context
otherwise requires, the term "Seller", wherever used in this Agreement, shall be
deemed to refer to each, any and/or all of Analog Devices, Inc. and each Seller
Subsidiary who owns or holds rights to any of the Purchased Assets or Licensed
Assets as of the Effective Date.

           SECTION 12.12. Counterparts. This Agreement may be executed in one or
more counterparts, and by the different parties hereto in separate counterparts,
each of which when 



                                       49

executed shall be deemed to be an original but all of which taken together shall
constitute one and the same agreement.

"Closing Date"), at the offices of Wilson Sonsini Goodrich & Rosati,
Professional Corporation, 650 Page Mill Road, Palo Alto, California 94304-1050,
unless a different date or place is agreed to by the Parties.

               2.3 Effect of the Merger. At the Effective Time of the Merger,

each share of Ridge Common Stock and Ridge Preferred Stock that is issued and
outstanding immediately prior to the Effective Time of the Merger (other than
shares owned by Adaptec) shall, by virtue of the Merger and without any action
on the part of the Ridge stockholders, be converted into that number of shares
of Adaptec Common Stock as is determined by (i) dividing Twenty One Million Two
Hundred Thousand dollars ($21,200,000) by the Average Closing Price (as defined
below) and (ii) dividing the result by the total number of issued and
outstanding shares of Ridge Common Stock and Ridge Preferred Stock which are not
held by Adaptec. For purposes hereof, the "Average Closing Price" shall mean the

<PAGE>   10
               3.2 Fractional Shares. No fractional share of Adaptec Common
Stock shall be issued in the Merger. In lieu thereof, each holder of shares of
Ridge Common Stock or Ridge Preferred Stock who would otherwise be entitled to
receive a fraction of a share of Adaptec Common Stock shall receive from Adaptec
an amount of cash (rounded to the nearest whole cent) equal to the product of
the fraction of a share of Adaptec Common Stock to which such holder would
otherwise be entitled, multiplied by the Average Closing Price of one share of
Adaptec Common Stock. For the purpose of determining fractional shares, all
shares of Adaptec Common Stock to be issued to any Ridge stockholder shall be
aggregated.

               3.3 Ridge Capital Stock Owned by Adaptec or Ridge. At the
Effective Time, (i) all shares of Ridge Common Stock or Ridge Preferred Stock
that are owned by Ridge as treasury stock shall be canceled and extinguished
without any conversion thereof, and (ii) each share of Ridge Common Stock or
Ridge Preferred Stock owned by Adaptec or any direct or indirect wholly owned
subsidiary of Adaptec immediately prior to the Effective Time shall remain
outstanding and shall become one fully paid and assessible share of the
Surviving Corporation.

               3.4 Capital Stock of Merger Sub. As of the Effective Time of the
Merger, each share of the capital stock of Merger Sub that is issued and
outstanding immediately prior to the Effective Time of the Merger shall, by
virtue of the Merger, be converted into and become one fully-paid and
nonassessable share of common stock, par value $0.001 per share, of the
Surviving Corporation.

               3.5    Exchange of Certificates.

                      (a) Exchange Agent. Prior to the Closing Date, Adaptec
shall appoint ChaseMellon Shareholder Services to act as the exchange agent (the
"Exchange Agent") in the Merger.

                      (b) Adaptec to Provide Adaptec Common Stock. Promptly
after the Effective Date of the Merger (but in no event later than ten business
days thereafter), Adaptec shall make available for exchange in accordance with
this Section 3, through such reasonable procedures as Adaptec may adopt, the
shares of Adaptec Common Stock issuable pursuant to Section 3.1 in exchange for
outstanding shares of Ridge Common Stock and Ridge Preferred Stock.

                      (c) Exchange Procedures. Within ten days after the
Effective Date of the Merger, the Exchange Agent shall mail to each holder of
record of a certificate or certificates, which immediately prior to the
Effective Time of the Merger represented outstanding shares of Ridge Common
Stock or Ridge Preferred Stock (the "Certificates") whose shares were converted
into Adaptec Common Stock pursuant to Section 3.1 hereof, (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and which shall be in such form and have such
other provisions as Adaptec and Ridge may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing Adaptec Common Stock. Upon surrender of a
Certificate for cancellation to the Exchange Agent or to such other agent or
agents as



                                       -4-
<PAGE>   11
may be appointed by Adaptec with the reasonable concurrence of the former Ridge
stockholders, together with such letter of transmittal, duly executed, the
holder of such Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of shares of Adaptec Common Stock to which
the holder of Ridge Common Stock or Ridge Preferred Stock is entitled pursuant
to Section 3.1 hereof. The Certificate so surrendered shall forthwith be
canceled. In the event of a transfer of ownership of Ridge Common Stock or Ridge
Preferred Stock which is not registered on the transfer records of Ridge, a
certificate representing the appropriate number of shares of Adaptec Common
Stock may be delivered to a transferee if the Certificate representing such
Ridge Common Stock or Ridge Preferred Stock is presented to the Exchange Agent
and accompanied by all documents required to evidence and effect such transfer
and to evidence that any applicable stock transfer taxes have been paid. From
and after the Effective Time of the Merger, until surrendered as contemplated by
this Section 3.4, each Certificate shall be deemed for all corporate purposes to
evidence the number of shares of Adaptec Common Stock into which the shares of
Ridge Common Stock or Ridge Preferred Stock represented by such Certificate have
been converted and the holder thereof shall have the rights with respect thereto
as provided by the DCGL.

                      (d) No Further Ownership Rights in Capital Stock of Ridge.
All Adaptec Common Stock delivered upon the surrender for exchange of shares of
Ridge Common Stock or Ridge Preferred Stock in accordance with the terms hereof
shall be deemed to have been delivered in full satisfaction of all rights
pertaining to such Ridge Common Stock or Ridge Preferred Stock. There shall be
no further registration of transfers on the stock transfer books of the
Surviving Corporation of Ridge Common Stock or Ridge Preferred Stock which were
outstanding immediately prior to the Effective Date of the Merger. If, after the
Effective Date of the Merger, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Section 3.5, provided that the presenting holder is listed on Ridge's
stockholder list as a holder of Ridge Common Stock or Ridge Preferred Stock.

               3.6 Escrow Agreement. At the Closing, the Indemnifying
Stockholders (as defined in Section 10.1) shall execute and deliver an escrow
agreement (the "Escrow Agreement") substantially in the form attached hereto as
Exhibit 3.6. Pursuant to the Escrow Agreement, 20% of the shares to be issued to
the Indemnifying Stockholders shall be placed in escrow for the purpose of
securing the indemnity obligations of the Indemnifying Stockholders with respect
to the representations and warranties set forth in Section 5 hereof, subject to
the terms, conditions and limitations specified in Section 10 hereof.

               3.7 Stock Option Plan. At the Effective Time of the Merger, all
options to purchase Ridge Common Stock then outstanding under the Ridge 1997
Stock Option Plan (the "Ridge Stock Option Plan") or held by the Willow Trust,
The Jonathan Mark Jackson Living Revocable Trust est. 8/28/97, The Jackson
Education Trust, The Robert J. Graham 1997 Irrevocable Trust and the Santa Clara
Group Trust (the "Trusts") shall be assumed by Adaptec in accordance with

                      REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.
                      SUCH SHARES MAY NOT BE SOLD, OFFERED FOR SALE,

of Ridge, enforceable against Ridge in accordance with its terms and conditions,
except as such enforceability may be limited by (i) bankruptcy laws and other
similar laws affecting creditors' rights generally and (ii) general principles

stockholders as set forth in Section 5.3(a) of the Ridge Disclosure Schedule.
All of the outstanding shares of Ridge's capital stock have been offered, issued

Security Interest upon any of its assets).

Schedule contains the unaudited balance sheet, statement of operations and
statement of cash flows (the "Financial Statements") as of and for the period
from its inception through March 31, 1998 (the "Fiscal Period End") for Ridge.
The Financial Statements (including the notes thereto) have been prepared in
accordance with generally accepted accounting principles applied on a consistent
basis throughout the periods covered thereby ("GAAP") and present fairly the
financial condition of Ridge as of such dates and the consolidated results of

balance sheet contained within the Financial Statements (the "Balance Sheet") or
acquired after the date thereof, free and clear of all Security Interests. No
Person other than Ridge will own at the time of the Closing any assets or
properties currently utilized in or reasonably necessary to the operations or
business of Ridge or situated on any of the premises of Ridge (other than the
lessors of assets subject to leases and the licensors of rights subject to
licenses.) There are no existing contracts, agreements, commitments or
arrangements with any Person to acquire any of the assets or properties of Ridge
(or any interest therein) except for this Agreement and those contracts entered
into during the Ordinary Course of Business for the sale of products and
services to customers of Ridge.

known or unknown, whether asserted or unasserted, whether absolute or
contingent, whether accrued or unaccrued, whether liquidated or unliquidated,

respects with all applicable laws (including rules, regulations, codes, plans,
injunctions, judgments, orders, decrees, rulings, and charges thereunder) of
federal, state, local, and foreign governments (and all agencies thereof). No
action, suit, proceeding, hearing, investigation, charge, complaint, claim,
demand, notice or inquiry has been filed or commenced against Ridge by any

authorizations that are listed on Section 5.11 of the Ridge Disclosure Schedule
are the only governmental authorizations that are necessary for the operations
of Ridge as they are presently conducted, except where the failure to obtain any

               5.12   Tax Matters.

                      (a) For purposes of this Agreement, "Taxes" means all

profits, severance, property, production, sales, use, value added, license,
excise, franchise, employment, withholding, capital stock, levies, imposts,
duties, transfer and registration fees or similar taxes or charges imposed on
the income, payroll, properties or operations of Ridge, together with any
interest, additions or penalties, deficiencies or assessments with respect
thereto and any interest in respect of such additions or penalties.

                      (b) Ridge has filed all reports and returns with respect
to any Taxes ("Tax Returns") that it was required to file. All such Tax Returns
were correct and complete in all respects, and no such Tax Returns are currently
the subject of audit. All Taxes owed by Ridge (whether or not shown on any Tax
Return) were paid in full when due or are being contested in good faith and are
supported by adequate reserves in the Financial Statements. Ridge has provided
adequate reserves in the Financial Statements for the payment of any taxes
accrued but not yet due and payable. Ridge is not currently the beneficiary of
any extension of time within which to file any Tax Return, and Ridge has not
waived any statute of limitations in respect of Taxes or agreed to any extension
of time with respect to any Tax assessment or deficiency.

                      (c) There is no dispute or claim concerning any Tax
liability of Ridge either (A) claimed or raised by any government or taxing
authority in writing or (B) based upon personal contact with any agent of such
authority. There are no tax liens of any kind upon any property or assets of

under Treas. Reg. Section 1.1502-6 (or any similar provision of state, local, or
foreign law), as a transferee or successor, by contract, or otherwise.

                      (e) The unpaid Taxes of Ridge (A) did not, as of the
Fiscal Period End, exceed by any amount the reserve for Tax liability (excluding

as adjusted for operations and transactions through the Closing Date in

Adverse Effect on Adaptec.

               6.12 Material Agreements. With respect to each agreement that has
been filed as an exhibit to the Adaptec SEC Reports: (A) the agreement is legal,
valid, binding, enforceable, and in full force and effect in all respects,
except as such enforceability may be limited by (i) bankruptcy laws and other
similar laws affecting creditors' rights generally and (ii) general principles
of equity, regardless of whether asserted in a proceeding in equity or at law;
(B) no party is in breach or default of any material provision of such
agreement, and no event has occurred, which with notice or lapse of time would
constitute such a breach or default, or permit termination, modification, or
acceleration, under the agreement; (C) no party has repudiated any material
provision of the agreement; and (D) Adaptec does not have any reason to believe
that the service called for thereunder cannot be supplied in accordance with its
terms and without resulting in a loss to Adaptec.

        7. Pre-Closing Covenants. With respect to the period between the
execution of this Agreement and the earlier of the termination of this Agreement
and the Effective Time of the Merger:

               7.1 General. Each of the Parties will use their best efforts to
take all action and to do all things necessary, proper, or advisable in order to
consummate and make effective the transactions contemplated by this Agreement as
promptly as possible (including satisfaction, but not waiver, of the closing
conditions set forth in Section 9 below).

               7.2 Notices and Consents. Ridge will give any notices to third
parties and will use its reasonable best efforts to obtain any third party
consents that Adaptec reasonably may request in connection with the matters
identified in Section 5.4 of the Ridge Disclosure Schedule. Notwithstanding the
foregoing, nothing in this Section 7.2 shall be construed to require any Party
to transfer or assign rights or other assets to a Person who is not a Party.

               7.3 Operation of Business. Ridge will not engage in any practice,
take any action, or enter into any transaction outside the Ordinary Course of
Business or except as disclosed in Section 5.9 of the Ridge Disclosure Schedule.
Without limiting the generality of the foregoing, Ridge will not (i) cause or
permit any amendment to its Certificate of Incorporation or Bylaws (except as
specifically contemplated by this Agreement), (ii) issue any capital stock or
issue or grant any options, warrants or rights to acquire any capital stock
(other than in connection with the exercise of stock options outstanding on the
date of this Agreement) or (iii) declare, set aside, or pay any dividend or make
any distribution with respect to its capital stock or redeem, purchase, or
otherwise acquire any of its capital stock (except from former employees,
directors and consultants in accordance with agreements providing for the
repurchase of shares upon termination of their services), or (iv) otherwise
engage in any practice, take any action, or enter into any transaction of the
sort described in Section 5.9 above. In addition, Ridge will comply with all
laws, statutes, ordinances, rules, regulations and orders applicable to it or to
the conduct of its business, except for violations that would not subject Ridge
to a penalty or loss that would constitute a Material Adverse Effect on Ridge.



                                      -27-
<PAGE>   34
               7.4 Preservation of Business. Ridge will use all commercially
reasonable efforts to keep its business and properties substantially intact,
including its present operations, physical facilities, working conditions, and
relationships with lessors, licensors, suppliers, customers, and employees.

               7.5 Access to Information. Ridge will permit Adaptec and its
representatives to have access at all reasonable times, and in a manner so as
not to interfere with the normal business operations of Ridge, to the business
and operations of Ridge. Neither such access, inspection and furnishing of
information to Adaptec and its representatives, nor any investigation by Adaptec
and its representatives, shall in any way diminish or otherwise effect Adaptec's
right to rely on any representation or warranty made by Ridge hereunder. All
information received or made available to Adaptec and its representatives
pursuant to this Section 7.5 shall be subject to and deemed covered by the terms
of the Master Mutual Nondisclosure Agreement dated June 20, 1997 between Adaptec
and Ridge.

               7.6 Notice of Developments. Each Party will give prompt written
notice to the others of any material adverse development causing a breach of any
of its own representations and warranties in Section 5 or Section 6 above. No
disclosure by any Party pursuant to this Section 7.6, however, shall be deemed
to amend or supplement the Ridge Disclosure Schedule or the Adaptec Disclosure
Schedule or to prevent or cure any misrepresentation, breach of warranty, or
breach of covenant.

               7.7 Amendment of Ridge Certificate of Incorporation. Ridge shall
use its best efforts to amend Article IX, Section 3 of Ridge's Certificate of
Incorporation to eliminate any right of any holders of Ridge Preferred Stock to
receive proceeds of a liquidation, dissolution or winding up of Ridge in excess
of the Original Issue Price (as defined in the Ridge Certificate of
Incorporation) applicable to such Ridge Preferred Stock.

               7.8    Stockholder's Agreements.

                      (a) Ridge shall use its best efforts to cause each holder
of Ridge Common Stock or Ridge Preferred Stock to execute and deliver to Adaptec
on or before the Closing Date, an agreement in the form of Exhibit 7.8 (a)
attached hereto (each a "Stockholder's Agreement"), setting forth, among other
things, certain restrictions upon the transferability of Adaptec Common Stock in
compliance with the Securities Act and representations in connection with the
continuity of interest requirement under the Code.

                      (b) The Stockholder's Agreements for each of the Ridge
employees listed on Exhibit 7.8(b) attached hereto (the "Senior Employees") (and
the Trusts to whom certain Senior Employees have transferred certain shares)
shall also include (i) a restriction on the transfer of the shares of Adaptec
Common Stock received by such individuals in the Merger, which restriction shall
lapse at the rate of one-sixth (1/6th) of such shares per each three month
period elapsing after the Effective Date of the Merger and (ii) an agreement to
be bound by the indemnification provisions set forth in Section 10 of this
Agreement.



                                      -28-
<PAGE>   35
                      (c) The Stockholder's Agreement for Graham (and the Trust
to whom Graham has transferred certain shares) shall be executed as of the date
hereof and shall also include (i) a restriction on the transfer of the shares
received by Graham in the Merger, which restriction shall lapse at the rate of
one-tenth (1/10th) of such shares per each three month period elapsing after the
Effective Date of the Merger, (ii) a provision prohibiting Graham from
transferring any Ridge capital stock or voting any shares of Ridge capital stock
in favor of any acquisition of Ridge (other than the acquisition contemplated by
this Agreement) prior to the earlier of the Effective Time of the Merger or the
termination of this Agreement and (iii) an agreement to be bound by the
indemnification provisions set forth in Section 10 of this Agreement.

               7.9 Employment Agreements. Prior to the Effective Time of the
Merger, Ridge will use its best efforts to cause the persons listed on Exhibit
7.9(a) attached hereto (the "Key Employees") to enter into an employment
agreement and covenant not to compete (the "Employment Agreement") in the form
attached hereto as Exhibit 7.9(b).

               7.10 Preparation of the Information Statement. As promptly as
practicable after the date hereof, Ridge will prepare an information statement
to be delivered to the stockholders and option holders of Ridge for purposes of
soliciting their consent to the Merger (the "Information Statement"). The
Information Statement shall be in form reasonably satisfactory to Adaptec and
its counsel. Adaptec will take any reasonable action required to be taken under
any applicable state securities or "blue sky" laws in connection with the
issuance of the Adaptec Common Stock in the Merger.

               7.11 Solicitation of Written Consents. Ridge will solicit the
written consent to the Merger from each of the stockholders and option holders
of Ridge as soon as practicable following the execution of this Agreement, and
shall use its best efforts to obtain such consent. The Board of Directors of
Ridge will recommend in the Information Statement the approval of the Merger by
the Ridge stockholders, which recommendation shall be unanimous except for any
abstention by any director designated by Adaptec.

               7.12 Exclusivity. Prior to the earlier of the Effective Time of
the Merger or the termination of this Agreement, Ridge will not and will use its
best efforts to cause its Affiliates not to (i) solicit, initiate, or encourage
the submission of any proposal or offer from any Person relating to the
acquisition of any capital stock or other voting securities, or any substantial
portion of the assets, of Ridge or its subsidiaries (including any acquisition
structured as a merger, consolidation, or share exchange) or (ii) participate in
any discussions or negotiations regarding, furnish any information with respect
to, assist or participate in, or facilitate in any other manner any effort or
attempt by any Person to do or seek any of the foregoing.

               7.13 Options. Prior to the Closing Date, Ridge shall take all
actions necessary and appropriate to allow for the assumption of options by
Adaptec pursuant to Section 8.6. Ridge shall use its best efforts to cause each
optionee to sign, prior to the Closing Date, an acknowledgment and waiver, in a
form acceptable to Adaptec and Ridge, providing for such optionee's acceptance
of the terms of



                                      -29-
<PAGE>   36
the option assumption and waiver of any right or claim against Ridge or Adaptec
with respect to such assumption.

        8.     Additional Agreements.

               8.1 General. In case at any time after the Effective Time of the
Merger any further action is necessary to carry out the purposes of this
Agreement, each of the Parties will take such further action (including the
execution and delivery of such further instruments and documents) as any other
Party reasonably may request, all at the sole cost and expense of the requesting
Party (unless the requesting Party is entitled to indemnification therefor under
Section 10 below).

               8.2 Litigation Support. In the event and for so long as any Party
actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction (A) on or
prior to the Effective Time of the Merger involving Ridge or (B) arising out of
Adaptec's operation of the business of the Surviving Corporation following the
Effective Time of the Merger in the manner in which it is presently conducted
and planned to be conducted, each of the other Parties will cooperate with the
Party and its counsel in the contest or defense, make available their personnel,
and provide such testimony and access to their books and records as shall be
reasonably necessary in connection with the contest or defense, all at the sole
cost and expense of the contesting or defending Party (unless the contesting or
defending Party is entitled to indemnification therefor under Section 10 below).

               8.3 Transition. Ridge will not take any action that is designed
or intended to have the effect of discouraging any lessor, licensor, customer,
supplier, or other business associate of Ridge from maintaining the same
business relationships with the Surviving Corporation after the Effective Time
of the Merger as it maintained with Ridge prior to the Effective Time of the
Merger.

               8.4 Ridge Employees. Except for the Ridge employees, who will be
executing Employment Agreements, all employees of Ridge as of the Closing will
be offered employment with Adaptec or the Surviving Corporation at compensation
levels at least as favorable as their current compensation at Ridge, subject to
Adaptec's standard employment terms and practices. Except as otherwise
prohibited, these employees will be eligible to participate in all standard
Adaptec benefit plans based upon seniority determined by their respective dates
of hire by Ridge except for the Adaptec Sabbatical Program for which eligibility
will be determined based on the Closing Date.

               8.5 S-3 Registration. Adaptec will use its best efforts to file,
within 30 days following the Effective Date of the Merger, a registration
statement on Form S-3 (or any successor form to Form S-3) so as to register the
Adaptec Common Stock issued in the Merger. The Company will (i) promptly give
written notice of the proposed registration to all Ridge stockholders who
received shares of Adaptec Common Stock in the Merger, and (ii) use its best
efforts to effect such registration (including, without limitation, the
execution of an undertaking to file post-effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and



                                      -30-
<PAGE>   37
appropriate compliance with applicable regulations issued under the Securities
Act and any other governmental requirements or regulations) as would permit or
facilitate the sale and distribution of all such shares of Adaptec Common Stock.

               8.6 Assumption of Options. At the Effective Time of the Merger,
each outstanding option to purchase shares of Ridge Common Stock under the Ridge
Stock Option Plan or held by the Trusts, whether vested or unvested, will be
assumed by Adaptec. Section 8.6 of the Ridge Disclosure Schedule sets forth a
true and complete list as of the date hereof of all holders of outstanding
options, including those granted under the Ridge Stock Option Plan, and includes
the number of shares of Ridge capital stock subject to each such option, the
exercise or vesting schedule, the exercise price per share and the term of each
such option. On the Closing Date, Ridge shall deliver to Adaptec an updated
Section 8.6 of the Ridge Disclosure Schedule current as of such date. Each such
option so assumed by Adaptec under this Agreement shall continue to have, and be
subject to, the same terms and conditions set forth in such option and, if
applicable, in the Ridge Stock Option Plan immediately prior to the Effective
Time, including provisions with respect to vesting, except that (i) such option
will be exercisable for that number of whole shares of Adaptec Common stock
equal to the product (rounded down to the nearest whole share) of the number of
shares of Ridge Common Stock that were issuable upon exercise of such option
immediately prior to the Effective Time multiplied by a fraction, the numerator
of which shall be 1,720,000 and the denominator of which shall be the total
number of shares of Ridge Common Stock that were issuable upon exercise of
options to purchase Ridge Common Stock then outstanding under the Ridge Stock
Option Plan or held by the Trusts, and (ii) the per share exercise price for the
shares of Adaptec Common stock issuable upon exercise of such assumed option
will be the last sale price for a share of Adaptec Common Stock on the trading
day immediately preceding the Closing Date, as reported on the Nasdaq National
Market. Consistent with either the terms of the Ridge Stock Option Plan and the
documents governing the outstanding options under such Plan or the documents
governing the outstanding options held by the Trusts, the Merger will not
terminate any of the outstanding options under the Ridge Stock Option Plan or
held by the Trusts or accelerate the exercisability or vesting of such options
or the shares of Adaptec Common Stock which will be subject to those options
upon Adaptec's assumption of the options in the Merger. It is the intention of
the parties that the options so assumed by Adaptec qualify, to the maximum
extent permissible, following the Effective Time of the Merger as incentive
stock options as defined in Section 422 of the Code to the extent such options
qualified as incentive stock options prior to the Effective Time of the Merger.
Adaptec shall take all corporate action necessary to reserve for issuance a
sufficient number of shares of Adaptec Common Stock for delivery upon the
exercise of the options assumed by Adaptec in accordance with this Section 8.6.
Adaptec will use its best efforts to file, within thirty (30) days following the
Effective Date of the Merger, a registration statement on Form S-8 (or any
successor form to Form S-8) so as to register the Adaptec Common Stock subject
to the options assumed by Adaptec pursuant to this Section 8.6 and shall use its
best efforts to effect such registration and to maintain the effectiveness of
such registration statement (and the current status of the prospectus contained
therein) for so long as such options remain outstanding.

        10. Survival of Representations, Warranties and Covenants;
Indemnification.

               10.1 Escrow Fund. As soon as practicable after the Effective Time
of the Merger, twenty percent (20%) of the shares of Adaptec Common Stock to be
issued to Graham, Samuel E. Bain, Jr. ("Bain"), the Key Employees, the Trusts
and 38 Silicon Valley Partners LLC (collectively, the "Indemnifying
Stockholders") in the Merger (the "Escrow Shares") shall be registered in the
name of, and be deposited with, an institution selected by Adaptec, and
reasonably acceptable to Ridge, to act as escrow agent (the "Escrow Agent"),
such deposit to constitute the "Escrow Fund" and to be governed by the terms set
forth herein and in the Escrow Agreement. The Escrow Fund shall be available to
compensate Adaptec for breaches of the representations and warranties of Ridge
contained in Section 5 hereof, as more specifically provided in this Section 10.

               10.2 Survival. All of the representations and warranties of the
Parties contained in Sections 5 and 6 shall survive the Closing (even if the
damaged Party knew or had reason to know of any misrepresentation or breach of
warranty at the time of the Closing) and continue in full force and effect for a
period of one year following the Closing (the "Survival Termination Date"). The
covenants and agreements in this Agreement shall survive the Closing except to
the extent they are specifically limited by their terms.

               10.3 Indemnification Provisions for Benefit of Adaptec. Subject
to the terms and conditions of this Section 10, in the event of any breach of
any of the representations, warranties, agreements or covenants of Ridge
contained herein, provided that Adaptec makes a written claim for
indemnification in the manner provided for in this Section 10 on or prior to the
Survival Termination Date, the Indemnifying Stockholders shall indemnify, defend
and hold harmless Adaptec and the Surviving Corporation, and their respective
officers, directors, agents and employees, from and against the entirety of any
and all actions, suits, proceedings, hearings, investigations, charges,
complaints, claims, demands, injunctions, judgments, orders, decrees, rulings,
damages, dues, penalties, fines, costs, reasonable amounts paid in settlement,
liabilities, obligations, taxes, liens, losses, expenses, and fees, including
court costs and reasonable attorneys' fees and expenses ("Adverse Consequences")
that Adaptec may suffer through and after the date of the claim for
indemnification resulting from, arising out of, in the nature of, or caused by
such breach.

               10.4   Limitations on Indemnification Claims.

                      (a) The Indemnifying Stockholders shall not be required to
provide indemnification for any Adverse Consequences unless and until the
aggregate amount of all Adverse Consequences under all claims of indemnification
asserted under this Section 10 ("Claims") exceeds $100,000, in which case
Adaptec shall be entitled to indemnification for the full amount of Adverse
Consequences, including the first $100,000. In determining the amount of any
Adverse Consequences attributable to a breach, any materiality standard
contained in a representation, warranty or covenant of Ridge shall be
disregarded.

Stockholders in respect to all Claims other than Capitalization - Related Claims
(as defined in Section 10.4(e) below) shall be the amount represented by Fund A.

                      (d) In the event that (i) one or more Capitalization -
Related Claims are asserted and (ii) Fund A is inadequate to cover both (A) the
Adverse Consequences in respect to such Capitalization - Related Claim(s) and
(B) all other Claims, then Fund B shall be available as an additional source of
indemnification solely for the excess amount of such Capitalization - Related
Claims.

                      (e) For purposes of this Section 10, "Capitalization -
Related Claims" shall mean Claims based upon a breach of the representations and
warranties contained in Section 5.2 (with respect to stockholder approval) and
Section 5.3.

                      (f) In any event, the maximum amount recoverable from the
Indemnifying Stockholders pursuant to this Section 10 shall be the amount of the
Escrow Fund, and no claim for indemnification shall be asserted against any of
the Indemnifying Stockholders or any other stockholders of Ridge other than
against the Escrow Fund pursuant to this Section 10 and the Escrow Agreement.

               10.5   Procedure for Indemnification Claims; Matters Involving 
Third Parties.

                      (a) In the event that Adaptec (the "Indemnified Party")
makes a Claim against the Indemnifying Stockholders, it shall notify the Ridge
Stockholders' Representatives in writing as to the existence, nature and amount
of such Claim (with reasonable specificity) (the "Claim Notice"). If the Ridge
Stockholders' Representatives dispute the existence or the amount of such Claim,
the Ridge Stockholders' Representatives shall notify the Indemnified Party in
writing (with reasonable specificity) within thirty (30) days following the
Ridge Stockholders' Representatives receipt of the Claim Notice (the "Response
Notice"). Upon such an exchange of written notification, the parties will
negotiate in good faith for up to thirty (30) days or such other period of time
as the parties mutually agree in an effort to resolve their differences with
respect to such Claim. In the event that the Claim is not resolved within such
period, the Indemnified Party may at any time thereafter submit the claim to the
Escrow Agent pursuant to the Escrow Agreement.

                      (b) If any third party shall notify an Indemnified Party
with respect to any matter (a "Third Party Claim") which may give rise to a
Claim against the Indemnifying Stockholders under this Section 10, the
Indemnified Party shall promptly notify the Ridge Stockholders' Representatives
thereof in writing; provided, however, that no delay on the part of the
Indemnified Party in notifying the Ridge Stockholders' Representatives shall
relieve the Indemnifying



                                      -36-
<PAGE>   43
Stockholders from any obligation hereunder unless and then solely to the extent
the Indemnifying Stockholders are prejudiced thereby.

                      (c) In the event that the Indemnified Party provides
notice to the Ridge Stockholders' Representatives of a Third Party Claim, the
Ridge Stockholders' Representatives will undertake control of the defense
thereof by counsel of their choosing, reasonably acceptable to the Indemnified
Party. The Indemnified Party may participate in the defense through its own
counsel at its own expense. If (i) the Ridge Stockholders' Representatives fail
or refuse to undertake the defense of such Third Party Claim within fifteen (15)
days after written notice of such Third Party Claim has been delivered to the
Ridge Stockholders' Representatives, (ii) the Third Party Claim seeks only
injunctive or other equitable relief or (iii) Adaptec determines, in good faith,
that the Third Party Claim, if determined adversely, could be reasonably
expected to have a Material Adverse Effect on Adaptec, the Indemnified Party
shall have the right to undertake the defense, compromise and settlement of such
Third Party Claim with counsel of its own choosing. The Indemnified Party and
the Ridge Stockholders' Representatives shall cooperate with each other in all
reasonable respects in connection with the defense of any Third Party Claim,
including making available records relating to such claim and furnishing
employees of the Indemnified Party or its Affiliates as may be reasonably
necessary for the preparation of the defense of any such Third Party Claim or
for testimony as witness in any proceeding relating thereto.

                      (d) Unless (i) the Ridge Stockholders' Representatives
shall have failed to fulfill their obligations under Section 10.5(c) or (ii)
Adaptec has assumed control of the defense of a Third Party Claim pursuant to
Section 10.5(c), no settlement by the Indemnified Party of any Third Party Claim
shall be made without the prior written consent by or on behalf of the
Indemnifying Stockholders. If the Ridge Stockholders' Representatives have
assumed the defense of a Third Party Claim, as contemplated hereunder, no
settlement of such Third Party Claim may be made by the Ridge Stockholders'
Representatives without the prior written consent by or on behalf of the
Indemnified Party, unless such settlement includes a complete release of all
claims against the Indemnified Party. Upon any settlement of a Third Party Claim
in accordance with this Section 10.5(d), the Parties shall instruct the Escrow
Agent to release funds from the Escrow Fund, to the extent available (and
subject to the limitations set forth in Section 10.4), to effect such
settlement.

        11.    Termination.

               11.1 Termination of the Agreement. Certain of the Parties may
terminate this Agreement as provided below:

                      (a) Adaptec and Ridge may terminate this Agreement as to
all Parties by mutual written consent at any time prior to the Closing;

                      (b) Adaptec may terminate this Agreement by giving written
notice to Ridge at any time prior to the Closing (A) in the event Ridge has
breached any representation, warranty, or covenant contained in this Agreement
in any respect, and the breach has continued without cure for a period of thirty
(30) days after the notice of breach; (B) if the Closing shall not



                                      -37-
<PAGE>   44
have occurred on or before June 30, 1998 by reason of the failure of any
condition precedent under Section 9.1 hereof (unless the failure results
primarily from Adaptec itself breaching any representation, warranty, or
covenants contained in this Agreement); or (C) in the event there has occurred a
Material Adverse Effect with respect to Ridge.

                      (c) Ridge may terminate this Agreement by giving written
notice to Adaptec at any time prior to the Closing (A) in the event Adaptec has
breached any representation, warranty, or covenant contained in this Agreement
in any respect, and the breach has continued without cure for a period of thirty
(30) days after the notice of breach; (B) if the Closing shall not have occurred
on or before June 30, 1998, by reason of the failure of any condition precedent
under Section 9.2 hereof (unless the failure results primarily from Ridge itself
breaching any representation, warranty, or covenants contained in this
Agreement); or (C) in the event there has occurred a Material Adverse Effect
with respect to Adaptec.

               11.2 Effect of Termination. If any Party terminates this
Agreement pursuant to Section 11.1 above, all rights and obligations of the
Parties hereunder shall terminate without any liability of any Party to any
other Party (except for any liability of any Party then in breach); provided,
however, that the confidentiality provisions contained in Section 7.5 above
shall survive termination.

        12.    Miscellaneous.

               12.1 Press Releases and Public Announcements. No Party shall
issue any press release or make any public announcement relating to the subject
matter of this Agreement prior to the Closing without the prior written approval
of Adaptec and Ridge; provided, however, that any Party may make any public
disclosure it believes in good faith is required by applicable law or any
listing or trading agreement concerning its publicly-traded securities (in which
case the disclosing Party will use its reasonable best efforts to advise the
other Parties prior to making the disclosure).

               12.2 No Third-Party Beneficiaries. This Agreement shall not
confer any rights or remedies upon any Person other than the Parties, the
stockholders and option holders of Ridge and their respective successors and
permitted assigns.

               12.3 Entire Agreement. This Agreement (including the documents
referred to herein) constitutes the entire agreement among the Parties and
supersedes any prior understandings, agreements, or representations by or among
the Parties, written or oral, to the extent they related in any way to the
subject matter hereof.

               12.4 Succession and Assignment. This Agreement shall be binding
upon and inure to the benefit of the Parties named herein and their respective
successors and permitted assigns. No Party may assign either this Agreement or
any of its rights, interests, or obligations hereunder without the prior written
approval of the other Parties; provided, however, that Adaptec may (i) assign
any or all of its rights and interests hereunder to one or more of its
Affiliates and (ii) designate one or more of its Affiliates to perform its
obligations hereunder (in any or all of which



                                      -38-
<PAGE>   45
cases Adaptec nonetheless shall remain responsible for the performance of all of
its obligations hereunder).

               12.5 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

hereunder to the intended recipient at the address set forth above using any
other means (including personal delivery, expedited courier, messenger service,

               12.8 Governing Law. This Agreement shall be governed by and
construed in accordance with the domestic laws of the State of Delaware without
giving effect to any choice or conflict of law provision or rule (whether of the
State of Delaware or any other jurisdiction) that would cause the application of
the laws of any jurisdiction other than the State of Delaware.

               12.9 Forum Selection; Consent to Jurisdiction. All disputes
arising out of or in connection with this Agreement shall be solely and
exclusively resolved by a court of competent jurisdiction in the State of
California. The Parties hereby consent to the jurisdiction of the Superior Court

               12.10 Amendments and Waivers. No amendment of any provision of
this Agreement shall be valid unless the same shall be in writing and signed by
Adaptec and Ridge. No waiver by any Party of any default, misrepresentation, or
breach of warranty or covenant hereunder, whether intentional or not, shall be
deemed to extend to any prior to subsequent default, misrepresentation, or
breach of warranty or covenant hereunder or affect in any way any rights arising

               12.11 Severability. Any term or provision of this Agreement that
is invalid or unenforceable in any situation in any jurisdiction shall not

               12.12 Expenses. Each of the Parties hereto will bear its own
costs and expenses (including legal fees and expenses) incurred in connection
with this Agreement and the transactions contemplated hereby, provided that (i)
if Ridge's out-of-pocket costs and expenses (including but not limited to legal
and accounting fees and any brokers', finders' or advisory fees but excluding
costs and expenses which are not solely and directly related to the Merger or
the exchange of Ridge Common Stock and Ridge Preferred Stock for Adaptec Common
Stock in accordance with the guidelines established in Revenue Ruling 73-54)
incurred in connection with this Agreement and the transactions contemplated
hereby ("Ridge's Expenses") are less than One Million Dollars ($1,000,000) then
the Ridge stockholders will be liable for one-half (1/2) of the amount of such
expenses and (ii) if Ridge's Expenses exceed One Million Dollars ($1,000,000)
then the Ridge stockholders will be liable for Five Hundred Thousand dollars
($500,000) of such expenses plus the amount by which such expenses exceed One
Million Dollars ($1,000,000). Ridge's expenses for



                                      -40-
<PAGE>   47
which the Ridge stockholders are liable are referred to as the "Excess
Transaction Expenses." A schedule of all Ridge's Expenses incurred or to be
incurred shall be submitted to Adaptec not later than two (2) business days
prior to the Closing. The number of shares of Adaptec Common Stock issuable to
Graham and Bain (in his individual capacity) pursuant to Section 3.1 shall be
reduced, on a pro rata basis, in a total amount equal to the dollar value of the
Excess Transaction Expenses, based on the Average Closing Price.

               12.13 Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring any Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation.

               12.14 Incorporation of Exhibits and Schedules. The Exhibits and
Schedules identified in this Agreement are incorporated herein by reference and
made a part hereof.

               12.15 Ridge Stockholders' Representatives. For the purposes of
this Agreement the Indemnifying Stockholders, without any further action on the
part of any such stockholder, shall be deemed to have consented to the
appointment of Graham and Bain as representatives of such stockholders (the
"Ridge Stockholders' Representatives"), as the attorneys-in-fact for and on
behalf of each Indemnifying Stockholder, and the taking by the Ridge
Stockholders' Representatives of any and all actions and the making of any
decisions required or permitted to be taken by them under this Agreement or the
Escrow Agreement, including, without limitation, the exercise of the power to
(i) execute the Escrow Agreement, (ii) receive or give any notice on behalf of
the Indemnifying Stockholders pursuant to this Agreement or the Escrow
Agreement, (iii) authorize delivery to Adaptec of the Escrow Fund, or any
portion thereof, in satisfaction of Claims, (iv) agree to, negotiate, enter into
settlements and compromises of, and demand arbitration and comply with orders of
courts and awards of arbitrators with respect to such Claims, (v) resolve any
Claims and (vi) take all actions necessary in the judgment of the Ridge
Stockholders' Representatives for the accomplishment of the foregoing and all of
the other terms, conditions and limitations of this Agreement and the Escrow
Agreement. Accordingly, the Ridge Stockholders' Representatives have unlimited
authority and power to act on behalf of each Indemnifying Stockholder with
respect to this Agreement and the Escrow Agreement and the disposition,
settlement or other handling of all claims, rights or obligations arising from
and taken pursuant to this Agreement. The Indemnifying Stockholders will be
bound by all actions taken by the Ridge Stockholders' Representatives in
connection with this Agreement and the Escrow Agreement, and Adaptec shall be
entitled to rely on any action or decision of the Ridge Stockholders'
Representatives evidenced by a written document executed by both of the Ridge
Stockholders' Representatives as the action or decision of each of the
Indemnifying Stockholders. The Ridge Stockholders' Representatives (in their
capacity as Ridge Stockholders' Representatives and not as Indemnifying
Stockholders) will incur no liability with respect to any action taken or
suffered by them in reliance upon any notice, direction, instruction, consent,
statement or other document believed by them to be genuine and to have been
signed by the proper person (and shall have no responsibility to determine the
authenticity thereof), nor for any other action or inaction, except their own
willful misconduct, bad faith or gross negligence. In all



                                      -41-
<PAGE>   48
questions arising under this Agreement or the Escrow Agreement, the Ridge
Stockholders' Representatives may rely on the advice of counsel, and for
anything done, omitted or suffered in good faith by the Ridge Stockholders'
Representatives based on such advice, the Ridge Stockholders' Representatives
(in their capacity as Ridge Stockholders' Representatives and not as
Indemnifying Stockholders) will not be liable to anyone. At any time during the
term of the Escrow Agreement, holders of a majority of the Escrow Shares may
appoint new Ridge Stockholders' Representatives by written consent by sending
notice and a copy of the written consent appointing such new Ridge Stockholders'
Representative signed by holders of a majority of the Escrow Shares to Adaptec
and the Escrow Agent. Such appointment will be effective upon the later of the
date indicated in the consent or the date such consent is received by Adaptec
and the Escrow Agent.

               12.16 Attorneys' Fees. If any legal proceeding or other action
relating to this Agreement is brought or otherwise initiated, the prevailing
party shall be entitled to recover reasonable attorneys fees, costs and
disbursements (in addition to any other relief to which the prevailing party may
be entitled).

        3.1 Adaptec California Common Stock. Upon the Effective Date of the
Merger, each share of Adaptec California Common Stock, par value $.001, issued
and outstanding immediately prior thereto shall, by virtue of the Merger and
without any action by the Constituent Corporations, the holder of such shares or
any other person, be changed and converted into and exchanged for one fully paid

Corporation. Each Purchase Right issued or issuable pursuant to the Second
Amended and Restated Rights Agreement (the "Rights Agreement") dated as of
December 5, 1996 between Adaptec, Inc. and Chase Mellon Shareholder Services,
LLC shall become exercisable, when and as described in the Rights Agreement, for

Purchase Right associated with it.

        3.2 Adaptec California Options, Stock Purchase Rights and Convertible

option or other right to purchase Adaptec California Common Stock or security
convertible into Adaptec California Common Stock shall become an outstanding and
unexercised option or right to purchase the Surviving Corporation's Common

the basis of one share of the Surviving Corporation's Common Stock for each
share of Adaptec California Common Stock issuable pursuant to any such option,
stock purchase right or convertible security, on the same terms and conditions
and at an exercise price per share equal to the exercise price applicable to any
such Adaptec California option, stock purchase right or convertible security at
the Effective Date of the Merger.

        A number of shares of the Surviving Corporation's Common Stock shall be
reserved for issuance upon the exercise of options, stock purchase rights or
convertible securities equal to the number of shares of Adaptec California
Common Stock so reserved immediately prior to the Effective Date of the Merger.

        3.3 Adaptec Delaware Common Stock. Upon the Effective Date of the
Merger, each share of Common Stock, $0.001 par value, of Adaptec Delaware issued

shares.

        3.4 Certificates. After the Effective Date of the Merger, each
outstanding certificate theretofore representing shares of Adaptec California
Common Stock shall be deemed for all purposes to represent the same number of
whole shares of the Surviving Corporation's Common Stock.

                                       IV

                                     GENERAL

                                  ARTICLE FOUR

        Part 1. Authorized Capital Stock. This Corporation is authorized to
issue two classes of shares of stock to be designated, respectively, "Common
Stock" and "Preferred Stock." The total number of shares which the Corporation
is authorized to issue is 401,000,000 shares consisting of:

               (i)  400,000,000 shares of Common Stock, $.001 per share par

value of which Two-Hundred Fifty Thousand (250,000) shares have been designated
Series A Participating Preferred Stock.

        Part 2. Undesignated Preferred Stock. The Board of Directors is hereby
authorized, subject to limitations prescribed by the Corporation Law, to provide
for the issuance of the shares of undesignated Preferred Stock in one or more
series, and by filing a certificate pursuant to the Corporation Law, to
establish from time to time the number of shares to be included in each such
series, and to fix the designation, powers, preferences and rights of the shares
of each such series and the qualifications, limitations or restrictions thereof.

               The authority of the Board of Directors with respect to each
series of undesignated Preferred Stock shall include, but not be limited to,
determination of the following:
<PAGE>   2

               (i) the number of shares constituting that series and the 
distinctive designation of that series;

               (ii) the dividend rate on the shares of that series, whether
dividends shall be cumulative, and if so, from which date or dates, and the
relative rights of priority, if any, of payment of dividends on shares of that
series;

               (iii) whether that series shall have voting rights in addition to
the voting rights provided by law, and if so, the terms of such voting rights;

               (iv) whether that series shall have conversion privileges, and if
so, the terms and conditions of such privileges, including provision for
adjustment of the conversion rate in such events as the Board of Directors shall
determine;

               (v) whether or not the shares of that series shall be redeemable,
and if so, the terms and conditions of such redemption, including the date or
dates upon or after which they shall be redeemable, and the amount per share
payable in case of redemption, which amount may vary under different conditions
and at different redemption rates;

               (vi) whether that series shall have a sinking fund for the
redemption or purchase of shares of that series, and if so, the terms in the
amount of such sinking funds;

               (vii) the rights of the shares of that series in the event of
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, and the relative rights of priority, if any, of payment of shares
of that series; and

               (viii) any other relative rights, preferences and limitations of
that series.

        Unless otherwise provided in the certificate establishing the
designation, powers, preferences, and rights of shares of Undesignated Preferred
Stock, the number of shares of any series of Undesig nated Preferred Stock may
be increased (but not above the total number of authorized shares of
Undesignated Preferred Stock) or decreased (but not below the number of shares
thereof then outstanding) by a certificate pursuant to the Corporation Law. In
case the number of shares of any series of Undesignated Preferred Stock shall be
decreased, the shares constituting such decrease shall resume the status which
they had prior to the adoption of the resolution originally fixing the number of
shares of such series of Undesignated Preferred Stock.

        Part 3. Series A Participating Preferred Stock. The Series A
Participating Preferred Stock shall have the following designations, powers,
preferences and relative and other special rights and qualifications,
limitations and restrictions:

               (i) Proportional Adjustment. In the event the Corporation shall
at any time after the issuance of any share or shares of Series A Participating
Preferred Stock (a) declare any dividend on Common Stock of the Corporation
("Common Stock") payable in shares of Common Stock, (b) subdivide the
outstanding Common Stock or (c) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the Corporation shall
simultaneously effect a

                                      -2-
<PAGE>   3



proportional adjustment to the number of outstanding shares of Series A
Participating Preferred Stock.

               (ii) Dividends and Distributions.

                      (a) Subject to the prior and superior right of the holders
of any shares of any series of Preferred Stock ranking prior and superior to the
shares of Series A Participating Preferred Stock with respect to dividends, the
holders of shares of Series A Participating Preferred Stock shall be entitled to
receive when, as and if declared by the Board of Directors out of funds legally
available for the purpose, quarterly dividends payable in cash on the last day
of January, April, July and October in each year (each such date being referred
to herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or fraction
of a share of Series A Participating Preferred Stock, in an amount per share
(rounded to the nearest cent) equal to 1,000 times the aggregate per share
amount of all cash dividends, and 1,000 times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions other than a
dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise), declared on the
Common Stock since the immediately preceding Quarterly Dividend Payment Date,
or, with respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series A Participating Preferred
Stock.

                      (b) The Corporation shall declare a dividend or
distribution on the Series A Participating Preferred Stock as provided in
paragraph (a) above immediately after it declares a dividend or distribution on
the Common Stock (other than a dividend payable in shares of Common Stock).

                      (c) Dividends shall begin to accrue on outstanding shares
of Series A Participating Preferred Stock from the Quarterly Dividend Payment
Date next preceding the date of issue of such shares of Series A Participating
Preferred Stock, unless the date of issue of such shares is prior to the record
date for the first Quarterly Dividend Payment Date, in which case dividends on
such shares shall begin to accrue from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date after
the record date for the determination of holders of shares of Series A
Participating Preferred Stock entitled to receive a quarterly dividend and
before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Participating Preferred Stock in an amount less than the
total amount of such dividends at the time accrued and payable on such shares
shall be allocated pro rata on a share-by-share basis among all such shares at
the time outstanding. The Board of Directors may fix a record date for the
determination of holders of shares of Series A Participating Preferred Stock
entitled to receive payment of a dividend or distribution declared thereon,
which record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

holders of shares of Series A Participating Preferred Stock and the holders of
shares of Common Stock shall vote together as one class on all matters submitted
to a vote of stockholders of the Corporation.

                      (c) Except as required by law, holders of Series A
Participating Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent they are entitled to vote
with holders of Common Stock as set forth herein) for taking any corporate
action.

               (iv) Certain Restrictions.

                      (a) The Corporation shall not declare any dividend on,
make any distribution on, or redeem or purchase or otherwise acquire for
consideration any shares of Common Stock after the first issuance of a share or
fraction of a share of Series A Participating Preferred Stock unless
concurrently therewith it shall declare a dividend on the Series A Participating
Preferred Stock as required by Section (ii) hereof.

                      (b) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Participating Preferred Stock as provided
in Section (ii) are in arrears, thereafter and until all accrued and unpaid
dividends and distributions, whether or not declared, on shares of Series A
Participating Preferred Stock outstanding shall have been paid in full, the
Corporation shall not:

                             1. declare or pay dividends on, make any other

dissolution or winding up) to the Series A Participating Preferred Stock;

                             2. declare or pay dividends on, make any other
distributions on any shares of stock ranking on a parity (either as to dividends

Preferred Stock, except dividends paid ratably on the Series A Participating
Preferred Stock and all such parity stock on which dividends are payable or in
arrears in proportion to the total amounts to which the holders of all such
shares are then entitled;

                             3. redeem or purchase or otherwise acquire for
consideration shares of any stock ranking on a parity (either as to dividends or
upon liquidation, dissolution or winding up) with the Series A Participating
Preferred Stock, provided that the Corporation may at 

                                      -4-
<PAGE>   5


any time redeem, purchase or otherwise acquire shares of any such parity stock
in exchange for shares of any stock of the Corporation ranking junior (either as
to dividends or upon dissolution, liquidation or winding up) to the Series A
Participating Preferred Stock;

                             4. purchase or otherwise acquire for consideration

terms as the Board of Directors, after consideration of the respective annual

                      (c) The Corporation shall not permit any subsidiary of the

               (v) Reacquired Shares. Any shares of Series A Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued

Directors, subject to the conditions and restrictions on issuance set forth
herein.

               (vi) Liquidation, Dissolution or Winding Up. Upon any

to any accrued and unpaid dividends on such shares of Series A Participating
Preferred Stock.

               (vii) Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Participating Preferred Stock shall at the same time be similarly
exchanged or changed in an amount per share equal to 1,000 times the aggregate
amount of stock, securities, cash and/or any other property (payable in kind),
as the case may be, into which or for which each share of Common Stock is
changed or exchanged.

               (x) Amendment. The Certificate of Incorporation of the
Corporation shall not be further amended in any manner which would materially
alter or change the powers, preference or special rights of the Series A
Participating Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority of the outstanding shares of
Series A Participating Preferred Stock, voting separately as a class.

               (xi) Fractional Shares. Series A Participating Preferred Stock

proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of all
other rights of holders of Series A Participating Preferred Stock.

amended after the filing of this Certificate of Incorporation to authorize
corporate action further eliminating or limiting the personal liability of
directors, then the liability of a director of the Corporation shall be
eliminated or limited to the fullest extent permitted by the Delaware General
Corporation Law, as so amended.

        Neither any amendment nor repeal of this Article, nor the adoption of
any provision of this Certificate of Incorporation inconsistent with this
Article, shall eliminate or reduce the effect of this Article in respect of any
matter occurring, or any cause of action, suit or claim that, but for this
Article, would accrue or arise, prior to such amendment, repeal or adoption of
an inconsistent provision.

                                 ARTICLE ELEVEN

        Except as otherwise provided herein, at the election of directors of the
Corporation, each holder of Common Stock shall be entitled to one vote for each
share held. No stockholder will be permitted to cumulate votes at any election
of directors.

                                 ARTICLE TWELVE

        Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide. The books of the Corporation may be kept
(subject to any provision contained in the laws of the State of Delaware)
outside of the State of Delaware at such place or places as may be designated
from time to time by the Board of Directors or in the Bylaws of the Corporation.

                                ARTICLE THIRTEEN

        The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Certificate of Incorporation, in the manner now or
hereafter prescribed by the laws of the State of Delaware, and all rights
conferred herein are granted subject to this reservation.

                                  ADAPTEC, INC.



                                    ARTICLE I

                                CORPORATE OFFICES


        I.1    REGISTERED OFFICE

        The registered office of the corporation shall be fixed in the
certificate of incorporation of the corporation.

        I.2    OTHER OFFICES

        The board of directors may at any time establish other offices at any
place or places where the corporation is qualified to do business.


                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS


        II.1   PLACE OF MEETINGS

        Meetings of stockholders shall be held at any place, within or outside
the State of Delaware, designated by the board of directors. In the absence of
any such designation, stockholders' meetings shall be held at the principal
executive office of the corporation.

        II.2   ANNUAL MEETING

        The annual meeting of stockholders shall be held each year on a date and
at a time designated by the board of directors. In the absence of such
designation, the annual meeting of stockholders shall be held on the fourth
Thursday of August in each fiscal year at 9:30 a.m. However, if such day falls
on a legal holiday, then the meeting shall be held at the same time and place on
the next succeeding full business day. At the meeting, directors shall be
elected and any other proper business may be transacted.

        II.3   SPECIAL MEETING
<PAGE>   6

        A special meeting of the stockholders may be called at any time by the
board of directors, the chairman of the board, the chief executive officer, the
president or by one or more stockholders holding shares in the aggregate
entitled to cast not less than ten percent (10%) of the votes at that meeting.

        If a special meeting is called by any person or persons other than the
board of directors, then the request shall be in writing, specifying the time of
such meeting and the general nature of the business proposed to be transacted,
and shall be delivered personally or sent by registered mail or by telegraphic
or other facsimile transmission to the chairman of the board, the chief
executive officer, the president, the chief operating officer, any corporate
vice president or the secretary of the corporation. The officer receiving the
request shall cause notice to be promptly given to the stockholders entitled to
vote, in accordance with the provisions of Sections 2.4 and 2.5 of these bylaws,
that a meeting will be held at the time requested by the person or persons
calling the meeting, so long as that time is not less than thirty-five (35) nor
more than sixty (60) days after the receipt of the request. If the notice is not
given within twenty (20) days after receipt of the request, then the person or
persons requesting the meeting may give the notice. Nothing contained in this
paragraph of this Section 2.3 shall be construed as limiting, fixing or
affecting the time when a meeting of stockholders called by action of the board
of directors may be held.

        II.4   NOTICE OF STOCKHOLDERS' MEETINGS

        All notices of meetings with stockholders shall be in writing and shall
be sent or otherwise given in accordance with Section 2.5 of these bylaws not
less than ten (10) (or, if sent by third-class mail pursuant to Section 2.5 of
these bylaws, thirty (30)) nor more than sixty (60) days before the date of the
meeting to each stockholder entitled to vote at such meeting. The notice shall
specify the place, date, and hour of the meeting, and (i) in the case of a
special meeting, the general nature of the business to be transacted (no
business other than that specified in the notice may be transacted) or (ii) in
the case of the annual meeting, those matters which the board of directors, at
the time of giving the notice, intends to present for action by the stockholders
(but any proper matter may be presented at the meeting for such action). The
notice of any meeting at which directors are to be elected shall include the
name of any nominee or nominees who, at the time of the notice, management
intends to present for election.

        II.5   MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

        Written notice of any meeting of stockholders shall be given either
personally, by first-class mail, by third-class mail, but only if the
Corporation has outstanding shares held of record by five hundred (500) or more
persons, or by telegraphic or other written communication. Notices not
personally delivered shall be sent postage prepaid and shall be addressed to the
stockholder at the address of that stockholder appearing on the books of the
corporation or given by the stockholder to the corporation for the purpose of
notice. Notice shall be deemed to have been given at such time as

                                       -2-

<PAGE>   7



it is delivered personally or deposited in the mail or sent by telegram or other
means of written communication.

        An affidavit of the mailing or other means of giving any notice of any
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

        II.6   QUORUM

        The holders of a majority of the shares entitled to vote, present in
person or represented by proxy, shall constitute a quorum for the transaction of
business at all meetings of stockholders, except as otherwise provided by
statute or by the certificate of incorporation. The stockholders present at a
duly called or held meeting at which a quorum is present may continue to do
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by at least a majority of the shares required to
constitute a quorum.

        When a quorum is present at any meeting, the affirmative vote of holders
of a the majority of the stock having voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which, by express provision of the laws of the
State of Delaware or of the certificate of incorporation or these bylaws, a
different vote is required, in which case such express provision shall govern
and control the decision of the question.

        II.7   ADJOURNED MEETING; NOTICE

        Any stockholders' meeting, annual or special, whether or not a quorum is
present, may be adjourned from time to time by the vote of the majority of the
shares represented at that meeting, either in person or by proxy, but in the
absence of a quorum, no other business may be transacted at that meeting, except
as provided in Section 2.6 of these bylaws.

        When any meeting of stockholders, either annual or special, is adjourned
to another time or place, unless these bylaws otherwise require, notice need not
be given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken. At the adjourned meeting the
corporation may transact any business that might have been transacted at the
original meeting. If the adjournment is for more than forty-five (45) days, or
if after the adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given to each stockholder of record
entitled to vote at the adjourned meeting in accordance with the provisions of
Sections 2.4 and 2.5 of these bylaws.

        II.8   VOTING

        The stockholders entitled to vote at any meeting of stockholders shall
be determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of 


                                      -3-
<PAGE>   8


Sections 217 and 218 of the General Corporation Law of Delaware (relating to
voting rights of fiduciaries, pledgers and joint owners of stock and to voting
trusts and other voting agreements).

        Except as provided in the last paragraph of this Section 2.8, or as may
be otherwise provided in the certificate of incorporation, each stockholder
shall be entitled to one vote for each share of capital stock held by such
stockholder.

        On any matter other than the election of directors, any stockholder may
vote part of the shares in favor of the proposal and refrain from voting the
remaining shares or vote them against the proposal, but, if the stockholder
fails to specify the number of shares which the stockholder is voting
affirmatively, it will be conclusively presumed that the stockholder's approving
vote is with respect to all shares which the stockholder is entitled to vote.

        If a quorum is present, the affirmative vote of the majority of the
shares represented and voting at a duly-held meeting (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the stockholders, unless the vote of a greater number, or voting
by classes, is required by law or by the certificate of incorporation.

        II.9    VALIDATION OF MEETING; WAIVER OF NOTICE

        Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.

        II.10   STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        The stockholders of the corporation may not take action by written
consent without a meeting but must take any such actions at a duly called annual
or special meeting.

        II.11   RECORD DATE FOR STOCKHOLDER NOTICE; VOTING

        For purposes of determining the stockholders entitled to notice of any
meeting or to vote thereat, the board of directors may fix, in advance, a record
date, which shall not be more than sixty (60) days nor less than ten (10) days
before the date of any such meeting and in such event only stockholders of
record on the date so fixed are entitled to notice and to vote, notwithstanding
any transfer of any shares on the books of the corporation after the record
date.


                                       -4-

<PAGE>   9



        If the board of directors does not so fix a record date, the record date
for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the business day next
preceding the day on which notice is given or, if notice is waived, at the close
of business on the business day next preceding the day on which the meeting is
held.

        A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting
unless the board of directors fixes a new record date for the adjourned meeting,
but the board of directors shall fix a new record date if the meeting is
adjourned for more than thirty (30) days from the date set for the original
meeting.

        The record date for any other purpose shall be as provided in Section
8.1 of these bylaws.

        II.12   PROXIES

        Each stockholder entitled to vote at a meeting of stockholders may
authorize another person or persons to act for him by a written proxy, signed by
the stockholder and filed with the secretary of the corporation, but no such
proxy shall be voted or acted upon after three (3) years from its date, unless
the proxy provides for a longer period. A proxy shall be deemed signed if the
stockholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by the stockholder or the
stockholder's attorney-in-fact. The revocability of a proxy that states on its
face that it is irrevocable shall be governed by the provisions of Section
212(e) of the General Corporation Law of Delaware.

        II.13   INSPECTORS OF ELECTION

        Before any meeting of stockholders, the board of directors shall appoint
one or more inspectors to act at the meeting and make a written report thereof.
The board of directors may designate one or more persons as alternate inspectors
to replace any inspector who fails to act. If no inspector or alternate is able
to act at a meeting of stockholders, the person presiding at the meeting shall
appoint one or more inspectors to act at the meeting.

        Such inspectors shall:

        (a) ascertain the number of shares outstanding and the voting power of
each;

        (b) determine the shares represented at a meeting and the validity of
proxies and ballots;

        (c) count all votes and ballots;

        (d) determine and retain for a reasonable period a record of the
disposition of any challenges made to any determination by the inspectors; and

        (e) certify their determination of the number of shares represented at
the meeting, and their count of all votes and ballots.

        The inspectors may appoint or retain other persons or entities to assist
the inspectors in the performance of the inspectors' duties.

                                       -5-

        II.14   LIST OF STOCKHOLDERS ENTITLED TO VOTE

        The officer who has charge of the stock ledger of a corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in

corporation may be made at a meeting of stockholders by or at the direction of
the board of directors or by any stockholder of the corporation entitled to vote
in the election of directors at the meeting who complies with the notice

to be timely must be so received not later than the close of business on the
tenth day following the day on which such notice of the date of the meeting was
mailed or such public disclosure was made. Such stockholder's notice shall set
forth (a) as to each person, if any, whom the stockholder proposes to nominate
for election or re-election as a director: (i) the name, age, business address

nomination which pertains to the nominee. No person shall be eligible for

the procedures set forth in this Section. The chairman of the meeting shall, if
the facts warrant, 


                                      -6-


<PAGE>   11

determine and declare at the meeting that a nomination was not made in
accordance with the procedures prescribed by these bylaws, and if he should so
determine, he shall so declare at the meeting and the defective nomination shall
be disregarded.

        II.16   ADVANCE NOTICE OF STOCKHOLDER BUSINESS

        At the annual meeting of the stockholders, only such business shall be
conducted as shall have been properly brought before the meeting. To be properly
brought before an annual meeting, business must be: (a) as specified in the
notice of meeting (or any supplement thereto) given by or at the direction of
the board of directors, (b) otherwise properly brought before the meeting by or
at the direction of the board of directors, or (c) otherwise properly brought
before the meeting by a stockholder. Business to be brought before the meeting
by a stockholder shall not be considered properly brought if the stockholder has
not given timely notice thereof in writing to the Secretary of the corporation.
To be timely, a stockholder's notice must be delivered to or mailed and received
at the principal executive officers of the corporation not less than twenty (20)
nor more than sixty (60) days prior to the meeting; provided, however, that in
the event that less than thirty (30) days' notice or prior public disclosure of

stockholder to be timely must be so received not later than the close of
business on the tenth day following the day on which such notice of the date of

stockholder proposes to bring before the annual meeting: (i) a brief description
of the business desired to be brought before the annual meeting and the reasons
for conducting such business at the annual meeting, (ii) the name and address of
the stockholder proposing such business, (iii) the class and number of shares of
the corporation, which are beneficially owned by the stockholder, (iv) any

these bylaws to the contrary, no business shall be conducted at any annual
meeting except in accordance with the procedures set forth in this Section. The
chairman of the annual meeting shall, if the facts warrant, determine and
declare at the meeting that business was not properly brought before the meeting
and in accordance with the provisions of this Section, and, if he should so
determine, he shall so declare at the meeting that any such business not
properly brought before the meeting shall not be transacted.


                                   ARTICLE III

                                    DIRECTORS


        III.1    POWERS

        Subject to the provisions of the General Corporation Law of Delaware and
any limitations in the certificate of incorporation or these bylaws relating to
action required to be approved by the 

                                      -7-
<PAGE>   12

stockholders or by the outstanding shares, the business and affairs of the
corporation shall be managed and all corporate powers shall be exercised by or
under the direction of the board of directors.

        III.2    NUMBER OF DIRECTORS

        The authorized number of directors shall be eight (8). This number may
be changed by a duly adopted amendment to the certificate of incorporation or by
an amendment to this bylaw adopted by the vote or written consent of the holders
of a majority of the stock issued and outstanding and entitled to vote or by
resolution of a majority of the board of directors.

        No reduction of the authorized number of directors shall have the effect
of removing any director before that director's term of office expires.

        III.3    ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS

        Except as provided in Section 3.4 of these bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Directors need not be stockholders unless so required by the
certificate of incorporation or these bylaws, wherein other qualifications for
directors may be prescribed. Each director, including a director elected to fill
a vacancy, shall hold office until his successor is elected and qualified or
until his earlier resignation or removal.

        Elections of directors need not be by written ballot.

        III.4    RESIGNATION AND VACANCIES

        Any director may resign effective on giving written notice to the
chairman of the board, the president, the secretary or the board of directors,
unless the notice specifies a later time for that resignation to become
effective. If the resignation of a director is effective at a future time, the
board of directors may elect a successor to take office when the resignation
becomes effective.

        Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; provided, a vacancy created by the removal of a director by the vote
of the stockholders or by court order may be filled only by the affirmative vote
of a majority of the shares represented and voting at a duly held meeting at
which a quorum is present (which shares voting affirmatively also constitute a
majority of the required quorum). Each director so elected shall hold office
until the next annual meeting of the stockholders and until a successor has been
elected and qualified.

        A vacancy or vacancies in the board of directors shall be deemed to
exist in the event of the death, resignation or removal of any director, or if
the board of directors by resolution declares vacant the office of a director
who has been declared of unsound mind by an order of court or 

                                      -8-


<PAGE>   13

convicted of a felony, or if the authorized number of directors is increased, or
if the stockholders fail, at any meeting of stockholders at which any director
of directors are elected, to elect the number of directors to be elected at that
meeting.

        The stockholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors.

        If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

        If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole board (as constituted immediately prior to any such increase), then
the Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten (10) percent of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office as aforesaid,
which election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

        III.5    PLACE OF MEETINGS; MEETINGS BY TELEPHONE

        Regular meetings of the board of directors may be held at any place

Special meetings of the board may be held at any place within or outside the
State of Delaware that has been designated in the notice of the meeting or, if

participating in the meeting can hear one another; and all such directors shall
be deemed to be present in person at the meeting.

        III.6    FIRST MEETINGS

        The first meeting of each newly elected board of directors shall be held
at such time and place as shall be fixed by the vote of the stockholders at the
annual meeting and no notice of such meeting shall be necessary to the newly
elected directors in order legally to constitute the meeting, provided a quorum
shall be present. In the event of the failure of the stockholders to fix the
time or 


                                      -9-

<PAGE>   14

place of such first meeting of the newly elected board of directors, or in the
event such meeting is not held at the time and place so fixed by the
stockholders, the meeting may be held at such time and place as shall be
specified in a notice given as hereinafter provided for special meetings of the
board of directors, or as shall be specified in a written waiver signed by all
of the directors.

        III.7    REGULAR MEETINGS

        Regular meetings of the board of directors may be held without notice at

may be called at any time by the chairman of the board, the chief executive
officer, the president, the chief operating officer or any two (2) directors.

        Notice of the date, time and place of special meetings shall be
delivered personally, by telephone, facsimile, telegram, electronic mail or
other comparable communication equipment to each director or sent by first-class
mail, charges prepaid, addressed to each director at that director's address as
it is shown on the records of the corporation. If the notice is mailed, it shall
be deposited in the United States mail at least four (4) days before the time of
the holding of the meeting. If the notice is delivered personally or by
telephone, facsimile, telegram, electronic mail or other comparable
communication equipment, it shall be delivered at least twelve (12) hours before
the time of the holding of the meeting. Any notice given personally or by
telephone, facsimile, telegram, electronic mail or other comparable
communication equipment may be communicated either to the director or to a
person at the office of the director who the person giving the notice has reason
to believe will promptly communicate it to the director. The notice need not
specify the purpose or the place of the meeting, if the meeting is to be held at
the principal executive office of the corporation.

        III.9    QUORUM

        A majority of the authorized number of directors shall constitute a
quorum for the transaction of business, except to adjourn as provided in Section
III.11 of these bylaws. Every act or decision done or made by a majority of the
directors present at a duly held meeting at which a quorum is present shall be
regarded as the act of the board of directors, subject to the provisions of the
certificate of incorporation and applicable law.

        A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

        III.10   WAIVER OF NOTICE


                                      -10-
<PAGE>   15


        Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the directors, or members of a committee of directors, need be specified in
any written waiver of notice unless so required by the certificate of
incorporation or these bylaws.

        III.11   ADJOURNMENT

        A majority of the directors present, whether or not constituting a
quorum, may adjourn any meeting to another time and place.

        III.12   NOTICE OF ADJOURNMENT

        Notice of the time and place of holding an adjourned meeting need not be
given, unless the meeting is adjourned for more than twenty-four (24) hours, in
which case notice of the time and place shall be given before the time of the
adjourned meeting, in the manner specified in Section III.8 of these bylaws, to
the directors who were not present at the time of the adjournment.

        III.13   BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        Unless otherwise restricted by the certificate of incorporation or these
bylaws, any action required or permitted to be taken at any meeting of the board
of directors, or of any committee thereof, may be taken without a meeting if all
members of the board or committee, as the case may be, shall individually or
collectively consent thereto in writing. Such action by written consent shall
have the same force and effect as a unanimous vote of the board of directors.
Such written consent and any counterparts thereof shall be filed with the
minutes of the proceedings of the board.

        III.14   FEES AND COMPENSATION OF DIRECTORS

        Directors and members of committees may receive such compensation, if
any, for their services and such reimbursement of expenses as may be fixed or
determined by resolution of the board of directors. This Section 3.14 shall not
be construed to preclude any director from serving the corporation in any other
capacity as an officer, agent, employee or otherwise and receiving compensation
for those services.

        III.15   APPROVAL OF LOANS TO OFFICERS

                                      -11-

        The corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the corporation or of its
subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation. The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the board of
directors shall approve, including, without limitation, a pledge of shares
of stock of the corporation. Nothing in this section contained shall be deemed
to deny, limit or restrict the powers of guaranty or warranty of the corporation
at common law or under any statute.

        III.16   REMOVAL OF DIRECTORS

        Unless otherwise restricted by statute, by the certificate of
incorporation or by these bylaws, any director or the entire board of directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors.

        No reduction of the authorized number of directors shall have the effect
of removing any director prior to the expiration of such director's term of
office.

The board may designate one (1) or more directors as alternate members of any
committee, who may replace any absent member at any meeting of the committee.
The appointment of members or alternate members of a committee requires the vote
of a majority of the authorized number of directors. Any committee, to the
extent provided in the resolution of the board, shall have all the authority of
the board, except with respect to (i) amend the certificate of incorporation
(except that a committee may, to the extent authorized in the resolution or
resolutions providing for the issuance of shares of stock adopted by the board
of directors as provided in Section 151(a) of the General Corporation Law of
Delaware, fix any of the preferences or rights of such shares relating to

or classes of stock of the corporation), (ii) adopt an agreement of merger or

meetings), Section 3.8 (special meetings and notice), Section 3.9 (quorum),
Section 3.10 (waiver of notice), Section 3.11 (adjournment), Section 3.12
(notice of adjournment), and Section 3.13 (action without a meeting), with such
changes in the context of those bylaws as are necessary to substitute the
committee and its members for the board of directors and its members; provided,
however, that the time of regular meetings of committees may also be called by
resolution of the board of directors and that notice of special meetings of
committees shall also be given to all alternate members, who shall have the
right to attend all meetings of the committee. The board of directors may adopt
rules for the government of any committee not inconsistent with the provisions
of these bylaws.

so acting shall have all the powers of, and be subject to all the restrictions
upon, the chief financial officer. The treasurer shall have such other powers
and perform such other duties as from time to time may be prescribed
respectively by the board of directors or these bylaws.

        V.14   ADMINISTRATIVE VICE PRESIDENTS

        In addition to the corporate vice presidents of the corporation as
provided in Section 5.10 of these bylaws and such subordinate officers as may be
appointed in accordance with section 5.3 of these bylaws, there may also be such
administrative vice presidents of the corporation as may be designated and
appointed from time to time by the chief executive officer of the corporation.
Administrative vice presidents shall perform such duties and have such powers as
from time to time may be determined by the chief executive officer or the board
of directors in order to assist the officers of the corporation in the
furtherance of their duties. In the performance of such duties and the exercise
of such powers, however, such administrative vice presidents shall have limited

                                      -16-


<PAGE>   21

authority to act on behalf of the corporation as the board of directors shall
establish, including but not limited to limitations on the dollar amount and on
the scope of the agreements or commitments that may be made by such

may not be exceeded by such individuals or altered by the chief executive
officer without further approval by the board of directors.


        V.15   AUTHORITY AND DUTIES OF OFFICERS

        In addition to the foregoing authority and duties, all officers of the
corporation shall respectively have such authority and perform such duties in
the management of the business of the corporation as may be designated from time
to time by the board of directors or the stockholders.

        VI.1    INDEMNIFICATION OF DIRECTORS AND OFFICERS

        The corporation shall, to the maximum extent and in the manner permitted
by the General Corporation Law of Delaware as the same now exists or may
hereafter be amended, indemnify any person against expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlement actually and
reasonably incurred in connection with any threatened, pending or completed
action, suit, or proceeding in which such person was or is a party or is
threatened to be made a party by reason of the fact that such person is or was a
director or officer of the corporation. For purposes of this Section 6.1, a
"director" or "officer" of the corporation shall mean any person (i) who is or
was a director or officer of the corporation, (ii) who is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was a
director or officer of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

        The corporation shall be required to indemnify a director or officer in
connection with an action, suit, or proceeding (or part thereof) initiated by
such director or officer only if the initiation of such action, suit, or
proceeding (or part thereof) by the director or officer was authorized by the
board of Directors of the corporation.

        Any repeal or modification of the foregoing provisions of this Article
shall not adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the time of such repeal or
modification.

        VI.2    INDEMNIFICATION OF OTHERS

                                      -17-
<PAGE>   22

        The corporation shall have the power, to the maximum extent and in the
manner permitted by the General Corporation Law of Delaware as the same now
exists or may hereafter be amended, to indemnify each of its employees and
agents (other than directors and officers) against expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlement actually and
reasonably incurred in connection with any threatened, pending or completed
action, suit, or proceeding, in which such person was or is a party or is
threatened to be made a party by reason of the fact that such person is or was
an employee or agent of the corporation. For purposes of this Section 6.2, an
"employee" or "agent" of the corporation (other than a director or officer)
shall mean any person (i) who is or was an employee or agent of the corporation,
(ii) who is or was serving at the request of the corporation as an employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, or (iii) who was an employee or agent of a corporation which was a
predecessor corporation of the corporation or of another enterprise at the

        VI.3    PAYMENT OF EXPENSES IN ADVANCE

        The corporation shall pay the expenses (including attorney's fees)
incurred by a director or officer of the corporation entitled to indemnification
hereunder in defending any action, suit or proceeding referred to in this
Section 6.1 in advance of its final disposition; provided, however, that payment
of expenses incurred by a director or officer of the corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an undertaking by the director or officer to repay all amounts
advanced if it should ultimately be determined that the director or officer is
not entitled to be indemnified under this Section 6.1 or otherwise.

        VI.4    INDEMNITY NOT EXCLUSIVE

        The rights conferred on any person by this Article shall not be
exclusive of any other rights which such person may have or hereafter acquire
under any statute, provision of the corporation's Certificate of Incorporation,
these bylaws, agreement, vote of the stockholders or disinterested directors or
otherwise.

        VI.5    INSURANCE INDEMNIFICATION

        The corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the corporation,
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,
whether or not the corporation would have the power to indemnify him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

                               RECORDS AND REPORTS


        VII.1    MAINTENANCE AND INSPECTION OF RECORDS

        The corporation shall, either at its principal executive office or at
such place or places as designated by the board of directors, keep a record of
its stockholders listing their names and addresses and the number and class of
shares held by each stockholder.

        Any stockholder of record, in person or by attorney or other agent,
shall, upon written demand under oath stating the purpose thereof, have the
right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger and a list of its stockholders and to make copies or
extracts therefrom. A proper purpose shall mean a purpose reasonably related to
such person's interest as a stockholder. In every instance where an attorney or
other agent is the person who seeks the right to inspection, the demand under
oath shall be accompanied by a power of attorney or such other writing that
authorizes the attorney or other agent to so act on behalf of the stockholder.
The demand under oath shall be directed to the corporation at its registered
office in Delaware or at its principal place of business.

        The officer who has charge of the stock ledger of a corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

        The record of stockholders shall also be open to inspection on the
written demand of any stockholder or holder of a voting trust certificate, at
any time during usual business hours, for a purpose reasonably related to the
holder's interests as a stockholder or as the holder of a voting trust
certificate.

        Any inspection and copying under this Section 7.1 may be made in person
or by an agent or attorney of the stockholder or holder of a voting trust
certificate making the demand.

        VII.2    MAINTENANCE AND INSPECTION OF BYLAWS

                                      -19-


<PAGE>   24

        The corporation shall keep at its principal executive office, or if its
principal executive office is not in the State of California, at its principal
business office in such state, the original or a copy of these bylaws as amended
to date, which bylaws shall be subject to inspection by the stockholders at all
reasonable times during office hours. If the principal executive office of the
corporation is outside the State of California and the corporation has no
principal business office in such state, the secretary shall, upon the written
request of any stockholder, furnish to that stockholder a copy of these bylaws
as amended to date.

        VII.3    MAINTENANCE AND INSPECTION OF OTHER CORPORATE RECORDS

        The accounting books and records, and the minutes of proceedings of the
stockholders and the board of directors and any committee or committees of the
board of directors, shall be kept at such place or places designated by the
board of directors or, in absence of such designation, at the principal
executive office of the corporation. The minutes shall be kept in written form
and the accounting books and records shall be kept either in written form or in
any other form capable of being converted into written form.

        The minutes and accounting books and records shall be open to inspection
upon the written demand of any stockholder or holder of a voting trust
certificate, at any reasonable time during usual business hours, for a purpose
reasonably related to the holder's interests as a stockholder or as the holder
of a voting trust certificate. The inspection may be made in person or by an
agent or attorney, and shall include the right to copy and make extracts. Such
rights of inspection shall extend to the records of each subsidiary corporation
of the corporation.

        VII.4    INSPECTION BY DIRECTORS

        Every director shall have the absolute right at any reasonable time to
inspect all books, records and documents of every kind and the physical
properties of the corporation and each of its subsidiary corporations. Such
inspection by a director may be made in person or by an agent or attorney, and
the right of inspection includes the right to copy and make extracts of
documents.

        The corporation shall also, on the written request of any stockholder,
mail to the stockholder a copy of the last annual, semi-annual or quarterly
income statement which it has prepared, and a balance sheet as of the end of
that period.

        The quarterly income statements and balance sheets referred to in this
section shall be accompanied by the report, if any, of any independent
accountants engaged by the corporation or the certificate of an authorized
officer of the corporation that the financial statements were prepared without
audit from the books and records of the corporation.

        VII.5    REPRESENTATION OF SHARES OF OTHER CORPORATIONS


                                      -20-

<PAGE>   25

        The chairman of the board, the chief executive officer, the president,
the chief operating officer, any corporate vice president, the treasurer, the
secretary or the chief financial officer of this corporation, or any other
person authorized by the board of directors or the president or a vice
president, is authorized to vote, represent, and exercise on behalf of this
corporation all rights incident to any and all shares of any other corporation
or corporations standing in the name of this corporation. The authority granted
herein may be exercised either by such person directly or by any other person
authorized to do so by proxy or power of attorney duly executed by such person
having the authority.


                                  ARTICLE VIII

                                 GENERAL MATTERS


        VIII.1    RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

        For purposes of determining the stockholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any other lawful
action, the board of directors may fix, in advance, a record date, which shall
not be more than sixty (60) days before any such action. In that case, only
stockholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided by law.

        If the board of directors does not so fix a record date, then the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the board adopts the applicable resolution, or the
sixtieth (60th) day before the date of that action, whichever is later.

        VIII.2    CHECKS

        From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

        VIII.3    EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS

        The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the 


                                      -21-


<PAGE>   26

name of and on behalf of the corporation; such authority may be general or
confined to specific instances. Unless so authorized or ratified by the board of
directors or within the agency power of an officer, no officer, agent or
employee shall have any power or authority to bind the corporation by any
contract or engagement or to pledge its credit or to render it liable for any
purpose or for any amount.

        VIII.4    STOCK CERTIFICATES; PARTLY PAID SHARES

        The shares of a corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the board of
directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the corporation by the chairman or vice-chairman of
the board of directors, or the president or vice-president, and by the chief
financial officer or an assistant treasurer, or the secretary or an assistant
secretary of such corporation representing the number of shares registered in
certificate form. Any or all of the signatures on the certificate may be a
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate has ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the corporation with the same effect as if he were such
officer, transfer agent or registrar at the date of issue.

        The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent
any such partly paid shares, upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

        VIII.5    SPECIAL DESIGNATION ON CERTIFICATES

        If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences, and the relative, participating, optional or other special


                                      -22-
<PAGE>   27

rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

        VIII.6    LOST CERTIFICATES

        Except as provided in this Section 8.6, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and canceled at the same time. The corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate theretofore issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify it against any claim that may be made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance of such new certificate or uncertificated shares.

        VIII.7    CONSTRUCTION; DEFINITIONS

        Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Delaware General Corporation Law shall
govern the construction of these bylaws. Without limiting the generality of this
provision, the singular number includes the plural, the plural number includes
the singular, and the term "person" includes both a corporation and a natural
person.

        VIII.8    DIVIDENDS

        The directors of the corporation, subject to any restrictions contained
in the certificate of incorporation, may declare and pay dividends upon the
shares of its capital stock pursuant to the General Corporation Law of Delaware.
Dividends may be paid in cash, in property, or in shares of the corporation's
capital stock.

        The directors of the corporation may set apart out of any of the funds
of the corporation available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing dividends, repairing or maintaining any property of the
corporation, and meeting contingencies.

        VIII.9    FISCAL YEAR

        The fiscal year of the corporation shall be fixed by resolution of the
board of directors and may be changed by the board of directors.

        VIII.10   TRANSFER OF STOCK

        Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignation or authority to 


                                      -23-


<PAGE>   28

transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate, and record the
transaction in its books.

        VIII.11   STOCK TRANSFER AGREEMENTS

        The corporation shall have power to enter into and perform any agreement
with any number of stockholders of any one or more classes of stock of the
corporation to restrict the transfer of shares of stock of the corporation of
any one or more classes owned by such stockholders in any manner not prohibited
by the General Corporation Law of Delaware.

        VIII.12   REGISTERED STOCKHOLDERS

        The corporation shall be entitled to recognize the exclusive right of a
person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.


                                   ARTICLE IX

                              EMERGENCY PROVISIONS


        IX.1    GENERAL

        The provisions of this Article shall be operative only during a national
emergency declared by the President of the United States or the person
performing the President's functions, or in the event of a nuclear, atomic, or
other attack on the United States or a disaster making it impossible or
impracticable for the corporation to conduct its business without recourse to
the provisions of this Article. The provisions of this Article in that event
shall override all other Bylaws of the corporation in conflict with any
provisions of this Article, and shall remain operative so long as it remains
impossible or impracticable to continue the business of the corporation
otherwise, but thereafter shall be inoperative; provided that all actions taken
in good faith pursuant to such provisions shall thereafter remain in full force
and effect unless and until revoked by action taken pursuant to the provisions
of the bylaws other than those contained in this Article.

        IX.2    UNAVAILABLE DIRECTORS

        All directors of the corporation who are not available to perform their
duties as directors by reason of physical or mental incapacity or for any other
reason or who are unwilling to perform their 

                                      -24-


<PAGE>   29

duties or whose whereabouts are unknown shall automatically cease to be
directors, with like effect as if they had resigned as directors, so long as
such unavailability continues.

        IX.3    AUTHORIZED NUMBER OF DIRECTORS

        The authorized number of directors shall be the number of directors
remaining after eliminating those who have ceased to be directors pursuant to
Section 9.2 of these bylaws, or the minimum number required by law, whichever
number is greater.

        IX.4    QUORUM

        The number of directors necessary to constitute a quorum shall be
one-third of the authorized number of directors as specified in Section 9.3 of
these bylaws, or such other minimum number as, pursuant to the law or lawful
decree then in force, it is possible for the bylaws of a corporation to specify.

        IX.5    CREATION OF EMERGENCY COMMITTEE

        If the number of directors remaining after eliminating those who have
ceased to be directors pursuant to Section 9.2 of these bylaws is less than the
minimum number of authorized directors required by law, then until the
appointment of additional directors to make up such required minimum, all the
powers and authority which the board of directors could by law delegate,
including all powers and authority which the board of directors could delegate
to a committee, shall be automatically vested in an emergency committee, and the
emergency committee shall thereafter manage the affairs of the corporation
pursuant to such powers and authority and shall have all such other powers and
authority as law or lawful decree may confer on any person or body of persons
during a period of emergency.

        IX.6    CONSTITUTION OF EMERGENCY COMMITTEE

        The emergency committee shall consist of all the directors remaining
after eliminating those who have ceased to be directors pursuant to Section 9.2
of these bylaws, provided that those remaining directors are not less than three
in number. If the remaining directors number less than three, the emergency
committee shall consist of three persons, who shall be the remaining director or
directors and either one or two officers or employees of the corporation, as the
remaining director or directors may in writing designate. If there is no
remaining director, the emergency committee shall consist of the three most
senior officers of the corporation who are available to serve, and if and to the
extent that officers are not available, the most senior employees of the
corporation. Seniority shall be determined in accordance with any designation of
seniority in the minutes of the proceedings of the board of directors, and in
the absence of such designation, shall be determined by rate of
remuneration. If there are no remaining directors and no officers or employees
of the corporation available, the emergency committee shall consist of three
persons designated in writing 


                                      -25-


<PAGE>   30

by the stockholder owning the largest number of shares of record as of the date
of the last record date.

        IX.7    POWERS OF EMERGENCY COMMITTEE

        The emergency committee, once appointed, shall govern its own procedures
and shall have power to increase the number of members thereof beyond the
original number, and if a vacancy or vacancies therein arises at any time, the
remaining member or members of the emergency committee shall have the power to
fill such vacancy or vacancies. If, at any time after its appointment, all
members of the emergency committee shall die or resign or become unavailable to
act for any reason whatsoever, a new emergency committee shall be appointed in
accordance with the foregoing provisions of this Article.

        IX.8    DIRECTORS BECOMING AVAILABLE

        Any person who has ceased to be a director pursuant to the provisions of
Section 9.2 of these bylaws and who thereafter becomes available to serve as a
director shall automatically become a member of the emergency committee.

        IX.9    ELECTION OF BOARD OF DIRECTORS

        The emergency committee shall, as soon after its appointment as is
practicable, take all requisite action to secure the election of a board of
directors, and, upon such election, all the powers and authorities of the
emergency committee shall cease.

        IX.10   TERMINATION OF EMERGENCY COMMITTEE

        If after the appointment of an emergency committee, a sufficient number
of persons who ceased to be directors pursuant to Section 9.2 of these bylaws
become available to serve as directors, so that if they had not ceased to be
directors as aforesaid, there would be enough directors to constitute the
minimum number of directors required by law, then all such persons shall
automatically be deemed to be reappointed as directors and the powers and
authorities of the emergency committee shall be at an end.


                                    ARTICLE X

                                   AMENDMENTS


        The original or other bylaws of the corporation may be adopted, amended
or repealed by the stockholders entitled to vote; provided, however, that the
corporation may, in its certificate of incorporation, confer the power to adopt,
amend or repeal bylaws upon the directors. The fact that 

                                      -26-
<PAGE>   31

such power has been so conferred upon the directors shall not divest the
stockholders of the power, nor limit their power to adopt, amend or repeal
bylaws.


                                   ARTICLE XI

                                   DISSOLUTION


        If it should be deemed advisable in the judgment of the board of
directors of the corporation that the corporation should be dissolved, the
board, after the adoption of a resolution to that effect by a majority of the
whole board at any meeting called for that purpose, shall cause notice to be
mailed to each stockholder entitled to vote thereon of the adoption of the
resolution and of a meeting of stockholders to take action upon the resolution.

        At the meeting a vote shall be taken for and against the proposed
dissolution. If a majority of the outstanding stock of the corporation entitled
to vote thereon votes for the proposed dissolution, then a certificate stating
that the dissolution has been authorized in accordance with the provisions of
Section 275 of the General Corporation Law of Delaware and setting forth the
names and residences of the directors and officers shall be executed,
acknowledged, and filed and shall become effective in accordance with Section
103 of the General Corporation Law of Delaware. Upon such certificate's becoming
effective in accordance with Section 103 of the General Corporation Law of
Delaware, the corporation shall be dissolved.

        Whenever all the stockholders entitled to vote on a dissolution consent
in writing, either in person or by duly authorized attorney, to a dissolution,
no meeting of directors or stockholders shall be necessary. The consent shall be
filed and shall become effective in accordance with Section 103 of the General
Corporation Law of Delaware. Upon such consent's becoming effective in
accordance with Section 103 of the General Corporation Law of Delaware, the
corporation shall be dissolved. If the consent is signed by an attorney, then
the original power of attorney or a photocopy thereof shall be attached to and

        XII.1   APPOINTMENT OF A CUSTODIAN IN CERTAIN CASES

                                      -27-

<PAGE>   32


        The Court of Chancery, upon application of any stockholder, may appoint
one or more persons to be custodians and, if the corporation is insolvent, to be
receivers, of and for the corporation when:

               (i) at any meeting held for the election of directors the
stockholders are so divided that they have failed to elect successors to
directors whose terms have expired or would have expired upon qualification of
their successors; or

               (ii) the business of the corporation is suffering or is
threatened with irreparable injury because the directors are so divided
respecting the management of the affairs of the corporation that the required
vote for action by the board of directors cannot be obtained and the
stockholders are unable to terminate this division; or

               (iii) the corporation has abandoned its business and has failed
within a reasonable time to take steps to dissolve, liquidate or distribute its
assets.

        XII.2   DUTIES OF CUSTODIAN

        The custodian shall have all the powers and title of a receiver
appointed under Section 291 of the General Corporation Law of Delaware, but the
authority of the custodian shall be to continue the business of the corporation
and not to liquidate its affairs and distribute its assets, except when the
Court of Chancery otherwise orders and except in cases arising under Sections
226(a)(3) or 352(a)(2) of the General Corporation Law of Delaware.

                                  ADAPTEC, INC.

                            INDEMNIFICATION AGREEMENT



        This Indemnification Agreement ("Agreement") is effective as of
_______________, 19__, by and between Adaptec, Inc., a Delaware corporation (the
"Company"or "Adaptec Delaware"), and FIELD (Name) ("Indemnitee").

        WHEREAS, Adaptec, Inc., a California corporation ("Adaptec California"),
and Indemnitee entered into an Indemnification Agreement, pursuant to which
Adaptec California agreed under certain conditions to indemnify Indemnitee;

        WHEREAS, on March 12, 1998, Adaptec California merged with and into
Adaptec Delaware (the "Merger"), following approval of the Merger by the Boards
of Directors of Adaptec California and Adaptec Delaware, the sole stockholder of
Adaptec Delaware and a majority of the shareholders of Adaptec California (which
approval also included approval of the adoption of this Agreement);

        WHEREAS, in order to induce Indemnitee to continue to provide services
to the Company, the Company wishes to provide for the indemnification of, and
advancement of expenses to, Indemnitee to the maximum extent permitted by law;

        WHEREAS, Indemnitee does not regard the current protection available as
adequate under the present circumstances, and the Indemnitee and other
directors, officers, employees, agents and fiduciaries of the Company may not be
willing to continue to serve in such capacities without additional protection;

        WHEREAS, the Company and Indemnitee recognize the continued difficulty
in obtaining liability insurance for the Company's directors, officers,
employees, agents and fiduciaries, the significant increases in the cost of such
insurance and the general reductions in the coverage of such insurance;

        WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers,
employees, agents and fiduciaries to expensive litigation risks at the same time
as the availability and coverage of liability insurance has been severely
limited; and

        WHEREAS, in view of the considerations set forth above, the Company
desires that, effective upon consummation of the Merger, Indemnitee shall be
indemnified by the Company as set forth herein;



<PAGE>   2
        NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth
below.

        1.     Certain Definitions.

               (a) "Change in Control" shall mean, and shall be deemed to have
occurred if, on or after the date of this Agreement, (i) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934,
as amended), other than a trustee or other fiduciary holding securities under an
employee benefit plan of the Company acting in such capacity or a corporation
owned directly or indirectly by the stockholders of the Company in substantially
the same proportions as their ownership of stock of the Company, becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing more than 20% of the total
voting power represented by the Company's then outstanding Voting Securities,
(ii) during any period of two consecutive years, individuals who at the
beginning of such period constitute the Board of Directors of the Company and
any new director whose election by the Board of Directors or nomination for
election by the Company's stockholders was approved by a vote of at least two
thirds (2/3) of the directors then still in office who either were directors at
the beginning of the period or whose election or nomination for election was
previously so approved, cease for any reason to constitute a majority thereof,
or (iii) the stockholders of the Company approve a merger or consolidation of
the Company with any other corporation other than a merger or consolidation
which would result in the Voting Securities of the Company outstanding
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into Voting Securities of the surviving
entity) at least 80% of the total voting power represented by the Voting
Securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation, or the stockholders of the Company approve a plan
of complete liquidation of the Company or an agreement for the sale or
disposition by the Company of (in one transaction or a series of related
transactions) all or substantially all of the Company's assets.

               (b) "Claim" shall mean any threatened, pending or completed
action, suit, proceeding or alternative dispute resolution mechanism, or any
hearing, inquiry or investigation that Indemnitee in good faith believes might
lead to the institution of any such action, suit, proceeding or alternative
dispute resolution mechanism, whether civil, criminal, administrative,
investigative or other.

               (c) References to the "Company" shall include, in addition to
Adaptec Delaware, any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger to which Adaptec Delaware (or
any of its wholly owned subsidiaries) is a party which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, employees, agents or fiduciaries, so that if Indemnitee is
or was a director, officer, employee, agent or fiduciary of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee, agent or fiduciary of another corporation,
partnership, joint venture, employee benefit plan, trust or other enterprise,
Indemnitee shall stand in the same position under the provisions of this
Agreement with respect to the resulting or surviving corporation as Indemnitee
would have with respect to such constituent corporation if



                                        2
<PAGE>   3
its separate existence had continued.

               (d) "Expenses" shall mean any and all expenses (including
attorneys' fees and all other costs, expenses and obligations incurred in
connection with investigating, defending, being a witness in or participating in
(including on appeal), or preparing to defend, to be a witness in or to
participate in, any action, suit, proceeding, alternative dispute resolution
mechanism, hearing, inquiry or investigation), judgments, fines, penalties and
amounts paid in settlement (if such settlement is approved in advance by the
Company, which approval shall not be unreasonably withheld) of any Claim
regarding any Indemnifiable Event and any federal, state, local or foreign taxes
imposed on the Indemnitee as a result of the actual or deemed receipt of any
payments under this Agreement.

               (e) "Expense Advance" shall mean an advance payment of Expenses
to Indemnitee pursuant to Section 3(a).

               (f) "Indemnifiable Event" shall mean any event or occurrence
related to the fact that Indemnitee is or was a director, officer, employee,
agent or fiduciary of the Company, or any subsidiary of the Company, or is or
was serving at the request of the Company as a director, officer, employee,
agent or fiduciary of another corporation, partnership, joint venture, trust or
other enterprise, or by reason of any action or inaction on the part of
Indemnitee while serving in such capacity.

               (g) "Independent Legal Counsel" shall mean an attorney or firm of
attorneys, selected in accordance with the provisions of Section 2(c) hereof,
who shall not have otherwise performed services for the Company or Indemnitee
within the last three years (other than with respect to matters concerning the
rights of Indemnitee under this Agreement, or of other indemnitees under similar
indemnity agreements).

               (h) References to "other enterprises" shall include employee
benefit plans; references to "fines" shall include any excise taxes assessed on
Indemnitee with respect to an employee benefit plan; and references to "serving
at the request of the Company" shall include any service as a director, officer,
employee, agent or fiduciary of the Company which imposes duties on, or involves
services by, such director, officer, employee, agent or fiduciary with respect
to an employee benefit plan, its participants or its beneficiaries; and if
Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to
be in the interest of the participants and beneficiaries of an employee benefit
plan, Indemnitee shall be deemed to have acted in a manner "not opposed to the
best interests of the Company" as referred to in this Agreement.

               (i) "Reviewing Party" shall mean any appropriate person or body
consisting of a member or members of the Company's Board of Directors or any
other person or body appointed by the Board of Directors who is not a party to
the particular Claim for which Indemnitee is seeking indemnification, or
Independent Legal Counsel.

               (j) "Voting Securities" shall mean any securities of the Company
that vote



                                        3
<PAGE>   4
generally in the election of directors.

        2.     Indemnification.

               (a) Indemnification of Expenses. The Company shall indemnify
Indemnitee to the fullest extent permitted by law if Indemnitee was or is or
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, any Claim by reason of (or
arising in part out of) any Indemnifiable Event against Expenses, including all
interest, assessments and other charges paid or payable in connection with or in
respect of such Expenses. Such payment of Expenses shall be made by the Company
as soon as practicable but in any event no later than five (5) business days
after written demand by Indemnitee therefor is presented to the Company.

               (b) Reviewing Party. Notwithstanding the foregoing, (i) the
obligations of the Company under Section 2(a) shall be subject to the condition
that the Reviewing Party shall not have determined (in a written opinion, in any
case in which the Independent Legal Counsel referred to in Section 2(c) hereof
is involved) that Indemnitee would not be permitted to be indemnified under
applicable law, and (ii) the obligation of the Company to make an Expense
Advance shall be subject to the condition that, if, when and to the extent that
the Reviewing Party determines that Indemnitee would not be permitted to be so
indemnified under applicable law, the Company shall be entitled to be reimbursed
by Indemnitee (who hereby agrees to reimburse the Company) for all such amounts
theretofore paid; provided, however, that if Indemnitee has commenced or
thereafter commences legal proceedings in a court of competent jurisdiction to
secure a determination that Indemnitee should be indemnified under applicable
law, any determination made by the Reviewing Party that Indemnitee would not be
permitted to be indemnified under applicable law shall not be binding and
Indemnitee shall not be required to reimburse the Company for any Expense
Advance until a final judicial determination is made with respect thereto (as to
which all rights of appeal therefrom have been exhausted or lapsed).
Indemnitee's obligation to reimburse the Company for any Expense Advance shall
be unsecured and no interest shall be charged thereon. If there has not been a
Change in Control, the Reviewing Party shall be selected by the Board of
Directors, and if there has been such a Change in Control (other than a Change
in Control which has been approved by a majority of the Company's Board of
Directors who were directors immediately prior to such Change in Control), the
Reviewing Party shall be the Independent Legal Counsel. If there has been no
determination by the Reviewing Party or if the Reviewing Party determines that
Indemnitee substantively would not be permitted to be indemnified in whole or in
part under applicable law, Indemnitee shall have the right to commence
litigation seeking an initial determination by the court or challenging any such
determination by the Reviewing Party or any aspect thereof, including the legal
or factual bases therefor, and the Company hereby consents to service of process
and to appear in any such proceeding. Absent such litigation, any determination
by the Reviewing Party shall be conclusive and binding on the Company and
Indemnitee.

               (c) Change in Control. The Company agrees that if there is a
Change in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control), then with respect to all matters
thereafter arising concerning the rights of Indemnitee to payments of Expenses
and Expense Advances under this Agreement or any other agreement or under the
Company's Certificate of Incorporation or Bylaws as now or hereafter in effect,
Independent Legal Counsel, if desired by Indemnitee, shall be selected by
Indemnitee and approved by the Company (which approval shall not be unreasonably
withheld). Such counsel, among other things, shall render its written opinion to
the Company and Indemnitee as to whether and to what extent Indemnitee would be
permitted to be indemnified under applicable law and the Company agrees to abide
by such opinion. The Company agrees to pay the reasonable fees of the
Independent Legal Counsel referred to above and to indemnify fully such counsel
against any and all expenses (including attorneys' fees), claims, liabilities
and damages arising out of or relating to this Agreement or its engagement
pursuant hereto. Notwithstanding any other provision of this Agreement, the
Company shall not be required to pay Expenses of more than one Independent Legal
Counsel in connection with all matters concerning a single Indemnitee, and such
Independent Legal Counsel shall be the Independent Legal Counsel for any or all
other Indemnitees unless (i) the Company otherwise determines or (ii) any
Indemnitee shall provide a written statement setting forth in detail a
reasonable objection to such Independent Legal Counsel representing other
Indemnitees.

               (d) Mandatory Payment of Expenses. Notwithstanding any other
provision of this Agreement other than Section 9 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
Claim regarding any Indemnifiable Event, Indemnitee shall be indemnified against
all Expenses incurred by Indemnitee in connection therewith.

        3.     Expenses; Indemnification Procedure.

               (a) Advancement of Expenses. The Company shall advance all
Expenses incurred by Indemnitee. The advances to be made hereunder shall be paid
by the Company to Indemnitee as soon as practicable but in any event no later
than five (5) business days after written demand by Indemnitee therefor to the
Company.

               (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a
condition precedent to Indemnitee's right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which indemnification will or could be sought
under this Agreement. Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee). In addition, Indemnitee shall give the Company such information
and cooperation as it may reasonably require and as shall be within Indemnitee's
power.



                                        5
<PAGE>   6
               (c) No Presumptions; Burden of Proof. For purposes of this
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
contendere, or its equivalent, shall not create a presumption that Indemnitee
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law. In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by the
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
applicable law, shall be a defense to Indemnitee's claim or create a presumption
that Indemnitee has not met any particular standard of conduct or did not have
any particular belief. In connection with any determination by the Reviewing
Party or otherwise as to whether the Indemnitee is entitled to be indemnified
hereunder, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

               (d) Notice to Insurers. If, at the time of the receipt by the
Company of a notice of a Claim pursuant to Section 3(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies. The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of the Indemnitee, all amounts payable as a result of such Claim in
accordance with the terms of such policies.

               (e) Selection of Counsel. In the event the Company shall be
obligated hereunder to pay the Expenses of any Claim the Company, if
appropriate, shall be entitled to assume the defense of such Claim with counsel
approved by Indemnitee (not to be unreasonably withheld) upon the delivery to
Indemnitee of written notice of the Company's election so to do. After delivery
of such notice, approval of such counsel by Indemnitee and the retention of such
counsel by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees of counsel subsequently incurred by Indemnitee with
respect to the same Claim; provided that, (i) Indemnitee shall have the right to
employ Indemnitee's separate counsel in any such Claim at Indemnitee's expense
and (ii) if (A) the employment of separate counsel by Indemnitee has been
previously authorized by the Company, (B) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and
Indemnitee in the conduct of any such defense, or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and expenses
of Indemnitee's separate counsel shall be at the expense of the Company.

        4.     Additional Indemnification Rights; Nonexclusivity.

               (a) Scope. The Company hereby agrees to indemnify the Indemnitee
to the fullest extent permitted by law, notwithstanding that such
indemnification is not specifically authorized by the other provisions of this
Agreement, the Company's Certificate of Incorporation, the Company's Bylaws (as
now or hereafter in effect) or by statute. In the event of any change after the
date of this



                                        6
<PAGE>   7
Agreement in any applicable law, statute or rule which expands the right of a
Delaware corporation to indemnify a member of its board of directors or an
officer, employee, agent or fiduciary, it is the intent of the parties hereto
that Indemnitee shall enjoy by this Agreement the greater benefits afforded by
such change. In the event of any change in any applicable law, statute or rule
which narrows the right of a Delaware corporation to indemnify a member of its
board of directors or an officer, employee, agent or fiduciary, such change, to
the extent not otherwise required by such law, statute or rule to be applied to
this Agreement, shall have no effect on this Agreement or the parties' rights
and obligations hereunder except as set forth in Section 9(a) hereof.

               (b) Nonexclusivity. The indemnification provided by this
Agreement shall be in addition to any rights to which Indemnitee may be entitled
under the Company's Certificate of Incorporation, its Bylaws (as now hereafter
in effect), any other agreement, any vote of stockholders or disinterested
directors, the General Corporation Law of the State of Delaware, or otherwise.
The indemnification provided under this Agreement shall continue as to
Indemnitee for any action taken or not taken while serving in an indemnified
capacity even though Indemnitee may have ceased to serve in such capacity.

        5. No Duplication of Payments. The Company shall not be liable under
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, provision of the Company's Certificate of
Incorporation, Bylaw (as now or hereafter in effect) or otherwise) of the
amounts otherwise indemnifiable hereunder.

        6. Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

        7. Mutual Acknowledgment. Both the Company and Indemnitee acknowledge
that in certain instances, federal law or applicable public policy may prohibit
the Company from indemnifying its directors, officers, employees, agents or
fiduciaries under this Agreement or otherwise. Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

        8. Liability Insurance. To the extent the Company maintains liability
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are provided to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee
is not an officer or director but is a key employee, agent or fiduciary.



                                        7
<PAGE>   8
        9. Exceptions. Notwithstanding any other provision of this Agreement,
the Company shall not be obligated pursuant to the terms of this Agreement:

               (a) Excluded Action or Omissions. To indemnify Indemnitee for
acts, omissions or transactions from which Indemnitee may not be indemnified
under applicable law.

               (b) Claims Initiated by Indemnitee. To indemnify or advance
expenses to Indemnitee with respect to Claims initiated or brought voluntarily
by Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment or insurance recovery, as the case may
be.

               (c) Lack of Good Faith. To indemnify Indemnitee for any expenses
incurred by the Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous.

               (d) Claims Under Section 16(b). To indemnify Indemnitee for
expenses and the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or any similar successor statute.

        10. Period of Limitations. No legal action shall be brought and no cause
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however, that if any shorter
period of limitations is otherwise applicable to any such cause of action, such
shorter period shall govern.

        11. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original.

        12. Binding Effect; Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), spouses, heirs and
personal and legal representatives. The Company shall require and cause any
successor (whether direct or indirect, and whether by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part, of
the business or assets of the Company, by written agreement in form and



                                        8
<PAGE>   9
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place. This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent or fiduciary (as applicable) of the Company
or of any other enterprise at the Company's request.

        13. Attorneys' Fees. In the event that any action is instituted by
Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, Indemnitee shall be entitled to be paid all Expenses incurred by
Indemnitee with respect to such action, regardless of whether Indemnitee is
ultimately successful in such action, and shall be entitled to the advancement
of Expenses with respect to such action, unless as a part of such action a court
of competent jurisdiction over such action determines that each of the material
assertions made by Indemnitee as a basis for such action was not made in good
faith or was frivolous. In the event of an action instituted by or in the name
of the Company under this Agreement to enforce or interpret any of the terms of
this Agreement, Indemnitee shall be entitled to be paid all Expenses incurred by
Indemnitee in defense of such action (including costs and expenses incurred with
respect to Indemnitee's counterclaims and cross-claims made in such action), and
shall be entitled to the advancement of Expenses with respect to such action,
unless as a part of such action a court having jurisdiction over such action
determines that each of Indemnitee's material defenses to such action was made
in bad faith or was frivolous.

        14. Notice. All notices, requests, demands and other communications
under this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and signed for by the party addressed, on the date of such
delivery, or (ii) if mailed by domestic certified or registered mail with
postage prepaid, on the third business day after the date postmarked. Addresses
for notice to either party are as shown on the signature page of this Agreement,
or as subsequently modified by written notice.

        15. Consent to Jurisdiction. The Company and Indemnitee each hereby
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum for adjudicating such a claim.

        16. Severability. The provisions of this Agreement shall be severable in
the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including, without limitations, each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not

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

RESULTS OF OPERATIONS

The Company's net revenues increased 8% to $1,007 million in fiscal 1998, 42% to
$934 million in fiscal 1997 and 41% to $659 million in fiscal 1996. The increase
in net revenues has been primarily attributable to increased shipments of the
Company's host adapters. This has reflected growth in the high-performance
microcomputer markets, demand for SCSI in the client/server environment, the
ongoing deployment of sophisticated operating systems and an increase in the use
of diverse peripherals such as high capacity hard drives, scanners and optical
drives. While net revenues and shipments of the Company's host adapters and
ASICs increased year over year between the 1996 and 1998 fiscal years, net
revenues for the fourth quarter of fiscal 1998 decreased 23% compared with
revenues for the fourth quarter of 1997. This decrease was primarily due to
lower sales of the Company's SCSI host adapters and peripheral technology
solutions. The demand for SCSI has been adversely impacted by the trend to lower
priced PCs for mainstream corporate desktop applications as well as enhancements
to the EIDE standard which is used predominantly in the desktop market. The
Company believes that the resulting shift of corporate buying towards lower
cost, more limited function PCs has been fueled by the delay in the introduction
of Windows NT 5.0 and Windows 98 and by the redirection of corporate management
information systems budgets towards resolving the Year 2000 issue and investing
in backbone network infrastructure. Net revenues from sales of the Company's
peripheral technology solutions have been adversely impacted by the turbulent
disk drive market and the recent instability in the Asian markets. The Company
presently expects that its sales growth is unlikely to resume before the third
quarter of fiscal 1999 at the earliest.

Gross margin in fiscal 1998 was 61% compared to 58% in both the 1997 and 1996
fiscal years. Gross margin in fiscal 1998 increased from fiscal 1997 primarily
due to proportionally greater shipments of the Company's higher margin SCSI host
adapters. Gross margins also increased due to the Company's continued focus on
component cost reductions and on improving manufacturing efficiencies.

Research and development expenditures in fiscal 1998 increased as a percentage
of revenues to 17% compared with 14% and 13% for the 1997 and 1996 fiscal years,
respectively. The percentage increase between fiscal 1997 and 1998 was primarily
due to lower than expected revenues for fiscal 1998. In absolute dollars,
spending for the three fiscal years was $173 million, $129 million and $88
million, respectively. The increase in spending in fiscal 1998 was primarily a
result of increased staffing levels to support the Company's commitment to
invest in newer hardware and software solutions, including RAID and external
storage, Fibre Channel, File Array and CD recordable software solutions.

Sales, marketing and administrative expenses in fiscal 1998 increased as a
percentage of revenues to 22% compared with 17% and 18% for the 1997 and 1996
fiscal years, respectively. The percentage increase between fiscal 1997 and 1998
was primarily due to lower than expected revenues for fiscal 1998. Spending for
the three fiscal years was $219 million, $163 million and $117 million,
respectively. These increases in actual spending were primarily a result of
increased staffing levels to support the Company's worldwide growth. In
addition, the Company increased advertising and promotional programs aimed at
leveraging the Company's brand image and generating demand for its products.

During fiscal 1997, the Company acquired complementary businesses recorded under
the purchase method of accounting, resulting in an aggregate write-off of
acquired in-process technology of approximately $90 million. Additionally, the
Company acquired one business under the pooling-of-interests method of
accounting. Professional fees totaling approximately $2 million were incurred in
connection with the acquisition and have been included in "write-off of acquired
in-process technology and other charges. The Company did not complete any
acquisitions during fiscal 1998, but did enter into agreements to acquire
Symbios, Inc. ("Symbios") and read channel technology from Analog Devices, Inc.
("ADI"). At March 31, 1998, these acquisitions were subject to regulatory
approval. In addition, subsequent to March 31, 1998, the Company acquired Ridge
Technologies. The Company believes that the integration of these acquisitions
will result in higher research and development and sales, marketing and
administrative expenditures in fiscal 1999. In addition, the Company anticipates
that it will incur significant one time charges in connection with these
acquisitions.

Interest income, net of interest expense for fiscal 1998 increased 94% from the
prior fiscal year due to higher cash and balances during the year primarily as a
result of cash generated by operations and proceeds received in connection with
$230 million of Convertible Subordinated Notes that the Company issued in
February 1997. The coupon interest rate associated with these notes is 4-3/4%.

<PAGE>   2

The Company's effective tax rate for fiscal years 1998, 1997 and 1996 was 26%,
37% and 25%, respectively. Excluding the effect of write-offs in fiscal 1998 and
write-offs of acquired in-process technology in fiscal 1997, the Company's
effective tax rate was 25% in each of these fiscal years. The accounting for
write-offs of acquired in-process technology changed in fiscal 1997 due to an
interpretation of SFAS 109 that the Company adopted upon its issuance. In fiscal
1996, the Company was allowed to gross-up the acquired in-process technology and
record a dollar-for-dollar credit against its tax provision, allowing the
Company to maintain its 25% effective rate. The difference between the Company's
25% effective tax rate and the U.S. statutory rate is primarily due to income
earned in Singapore where the Company is subject to a lower effective tax rate
resulting from a tax holiday relating to certain of its products. The terms of
the tax holiday provide that profits derived from certain products will be
exempt from tax through 2006, subject to certain conditions.

LIQUIDITY AND CAPITAL RESOURCES

OPERATING ACTIVITIES Net cash generated from operating activities during fiscal
1998 was $245 million compared to $245 million in fiscal 1997 and $116 million
in fiscal 1996. Cash from operating activities for fiscal 1998 was primarily
attributable to net income of $173 million adjusted by non-cash items including
the cumulative effect of a change in accounting principle of $9 million,
depreciation and amortization of $43 million, provision for doubtful accounts of
$4 million and impairment losses totaling $7 million. Increases in accounts
receivable and inventories were largely offset by decreases in other assets and
prepaid expenses and other and an increase in accounts payable.

Cash from operating activities for fiscal 1997 was primarily attributable to net
income of $108 million adjusted by non-cash items including net write-off of
acquired in-process technology of $89 million and depreciation and amortization
of $29 million. Increases in accounts receivable and prepaid expenses and other
were largely offset by increases in accounts payable and accrued liabilities.
Cash generated from operating activities for fiscal 1996 was primarily a result
of the overall growth of the Company's operations.

INVESTING ACTIVITIES Net cash used for investing activities during fiscal 1998
was $346 million compared to $221 million for fiscal 1997 and $97 million for
fiscal 1996. During fiscal 1998 the Company purchased $240 million of marketable
securities consisting primarily of municipal bonds, corporate bonds and
government securities, all of which are of high investment grade. The Company
also continued to make various building and leasehold improvements to its
facilities and to invest in equipment for product development and manufacturing
to support current and future business requirements. Purchases of property and
equipment of $98 million during fiscal 1998 included $11 million for land
located in Irvine, California. During fiscal 1999, the Company anticipates that
it will invest approximately $70 million in property and equipment to support
its growth. The Company may also make investments in "take or pay" prepayments
to support future wafer requirements or in acquiring complimentary businesses,
products or technologies.

During fiscal 1997, the Company made payments of $107 million, net of cash
acquired, in connection with the acquisitions of Western Digital's Connectivity
Solutions Group, CD-Recordable software technology from Corel, Inc., Data
Kinesis Inc., Sigmax Technologies Inc., Toast CD-R technology for the Macintosh
platform, and certain assets of Skipstone, Inc.. Additionally, the Company
acquired Cogent Data Technologies, Inc. in a transaction accounted for as a
pooling of interest through the issuance of 3 million shares of its common
stock. During fiscal 1997, the Company purchased property and equipment totaling
$88 million and entered into an agreement with Lucent Technologies, Inc.
("Lucent") to sell $21 million of equipment that it had previously purchased in
connection with a separate agreement that ensured availability of certain levels
of wafer capacity from Lucent. The new agreement canceled the initial capacity
agreement and required Lucent to purchase the equipment from the Company in
fiscal 1998.

FINANCING ACTIVITIES During fiscal 1998 financing activities provided $10
million compared to $203 million provided during fiscal 1997 and $5 million
during fiscal 1996. Cash provided by financing activities during fiscal 1998 and
fiscal 1996 was primarily through the issuance of common stock to employees
through its stock option and employee stock purchase plans for $39 million and
$16 million, respectively, offset in both years by repurchases of stock and
payments on debt.

Advance payments totaling $18 million were made in fiscal 1998 against a
promissory note for $35 million in connection with an agreement with Taiwan
Semiconductor Manufacturing Co., Ltd. ("TSMC") whereby the Company will make
advance payments totaling $35 million to secure additional wafer capacity for
future technology through 2001. In addition the Company made payments in fiscal
1998 totaling $3 million related to a term loan and repurchased common stock
totaling $8 million.

During fiscal 1997, the Company issued $230 million of 4-3/4% Convertible
Subordinated Notes due February 1, 2004, for which the Company received net
proceeds of $224 million. The notes provide for semi-annual interest payments
each February 1 and August 1, commencing on August 1, 1997. The holders of the
notes will be entitled at any time on or after May 5, 1997 through maturity to
convert the notes into common stock at a conversion price of $51.66 per share.
The notes are redeemable, in whole or in part, at the option of the Company, at
any time on or after February 3, 2000 at declining premiums to par. Debt
issuance costs are being amortized ratably over the term of the notes. During
fiscal 1997, the Company paid a $46 million short term note issued to TSMC in
connection with an agreement to ensure increased wafer capacity for future
technology through 2001. The Company also received proceeds from the issuance of
common stock totaling $28 million under its Stock Option and Employee Stock
Purchase Plans.

The Company has an unsecured $17 million revolving line of credit under which
there were no outstanding borrowings as of March 31, 1998.

In February 1998, the Company entered into an agreement to purchase all of the
outstanding stock of Symbios for approximately $768 million in cash. The
completion of the Symbios acquisition is subject to regulatory approval. The
Company anticipates arranging for two rounds of financing to fund the
acquisition. The first round is expected to be a bank revolving loan for
approximately $500 million to be available upon close of the acquisition.
Following the close, the Company expects to undertake a public debt-offering for
approximately $250 million. The proceeds of the debt offering would generally be
used to pay down the bank loan. There can be no assurance that such financings
will be available on favorable terms, or at all. The Company's liquidity is
affected by various factors, some based on continuing operations of the business
and others related to the industry and global economies. Although the Company's
cash position will fluctuate based on the timing of these factors, the Company
believes that existing working capital combined with expected cash generated
from operations and available sources of financing will be sufficient to meet
its cash requirements throughout fiscal 1999.

CHANGE IN ACCOUNTING POLICY

EITF 97-13 was issued in November 1997 and requires that business process
reengineering costs be expensed as incurred. The transition provisions of EITF
97-13 require that companies that had previously capitalized such business
process reengineering costs charge off any unamortized amounts as the cumulative
effect of a change in accounting principle. The cumulative effect of the change
to the Company was to decrease net income by $9 million.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 130 ("SFAS 130") "Reporting Comprehensive
Income," which establishes standards for reporting and displaying comprehensive
income and its components in a full set of general purpose statements. The
disclosure requirements of SFAS 130 are first expected to be reflected in the
Company's first quarter of fiscal 1999 interim financial statements. In June
1997, the FASB issued SFAS No. 131 "Disclosures and Segments of an Enterprise
and Related Information," which establishes annual and interim reporting
standards for an enterprise's business segments and related disclosures about
its products, services, geographic areas and major customers. SFAS 131 will be
first reflected in the Company's fiscal 1999 Annual Report. Adoption of SFAS 130
and SFAS 131 will not impact the Company's consolidated financial position,
results of operations or cash flows.

In October 1997, the American Institute of Certified Public Accountants'
("AICPA") issued Statement of Position ("SOP") 97-2 "Software Revenue
Recognition". This SOP supersedes SOP 91-1 "Software Revenue Recognition" and
provides more stringent guidelines for revenue recognition. Adoption of this
statement is not expected to have a material effect on the Company's
consolidated financial position, results of operations or cash flows.

MARKET RISK DISCLOSURE

At March 31, 1998, the Company's investment portfolio consisted of fixed income
securities, excluding those classified as cash equivalents, of $470 million (see
Note 4 of Notes to Consolidated Financial Statements). These securities, are
subject to interest rate risk and will decline in value if market interest rates
increase. If market interest rates were to increase immediately and uniformly by
10% from levels as of March 31, 1998, the decline in the fair value of the
portfolio would not be material.

<PAGE>   4

The Company's long term debt bears interest at a fixed rate while the note
payable to TSMC bears no interest. Accordingly, an immediate 10% change in
interest rates would not result in the Company's long-term debt or note payable
to TSMC having any effect on the Company's results of operations.

The Company enters into forward exchange contracts to hedge certain firm
commitments denominated in foreign currencies. The Company does not use
derivative financial instruments for trading or speculative purposes. Forward
exchange contracts are denominated in the same currency as the underlying
transaction (primarily Singapore dollars) and the terms of the forward foreign
exchange contracts generally match the terms of the underlying transactions. The
effect of an immediate 10% change in exchange rates on the forward exchange
contracts would not be material to the Company's financial condition or results
of operation.

YEAR 2000

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 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.

RISK FACTORS

This annual report may contain forward-looking statements regarding future
events or the future performance of the Company. Actual events or results could,
of course, differ materially. Various factors could adversely affect its results
of operations in the future including its dependence on the high-performance
microcomputer, server and peripherals markets, changes in product mix,
competitive pricing pressures, changes in technological standards, dependence on
wafer suppliers and other subcontractors, changes in product costs, certain
risks associated with acquisitions of other companies or businesses that the
Company may make from time to time, issues related to distributors, dependence
on key personnel, risks associated with international operations, risks
associated with implementation and utilization of new systems, and risks
associated with intellectual property or general economic downturns. In
addition, there can be no assurance that the Company will receive regulatory
approval to consummate the Symbios acquisition nor can there be any assurance
that financing required to fund the acquisition will be available on favorable
terms, or at all. For a more complete discussion of these factors, please refer
to the Business section of the Company's Annual Report on Form 10-K for the
fiscal year ended March 31, 1998 and the Company's other public filings it makes
from time to time.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries after elimination of intercompany transactions and
balances. Certain prior year amounts have been reclassified to conform to the
current year presentation. The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the consolidated
financial statements and accompanying notes. Actual results could differ from
those estimates. In March 1998, the Company was reincorporated in the State of
Delaware. The accompanying consolidated financial statements have been
retroactively restated to give effect to the reincorporation.

FOREIGN CURRENCY TRANSLATION

For foreign subsidiaries whose functional currency is the local currency, the
Company translates assets and liabilities to U.S. dollars using year end
exchange rates and translates revenues and expenses using average exchange rates
during the year. Exchange gains and losses arising from translation of foreign
entity financial statements are included as a component of stockholders' equity.

For foreign subsidiaries whose functional currency is the U.S. dollar, certain
assets and liabilities are remeasured at the year end or historical rates as
appropriate. Revenues and expenses are remeasured at the average rates during
the year. Currency transaction gains and losses are recognized in current
operations and have not been material to the Company's operating results in any
period.

CASH EQUIVALENTS AND MARKETABLE SECURITIES

Cash equivalents consist of highly liquid investments with original maturities
of three months or less. The Company's marketable securities are classified as
available for sale and, at the balance sheet date, are reported at fair market
value which approximates cost.

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 primarily in municipal bonds, corporate bonds and
government securities, all of which are of high investment grade. The Company,
by policy, limits the amount of credit exposure through diversification and
investment in highly rated securities. Sales to customers are 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 doubtful
accounts based upon the expected collectibility of all accounts receivable.
During fiscal 1998 the Company increased its allowance for bad debts by $4
million to reflect current business conditions in the disk drive market,
otherwise the Company has historically not experienced significant losses on
accounts receivable.

DERIVATIVE FINANCIAL INSTRUMENTS

The Company enters into foreign currency contracts in order to reduce the impact
of certain foreign currency fluctuations. Firmly committed transactions
denominated in foreign currencies are hedged with forward exchange contracts.
Gains and losses related to hedges of firmly committed transactions are deferred
and recognized in income when the hedged transaction occurs. The Company does
not hold or issue derivative financial instruments for trading or speculative
purposes.

FAIR VALUE OF FINANCIAL INSTRUMENTS

For certain of the Company's financial instruments, including cash and cash
equivalents, marketable securities, accounts receivable, notes payable and
accounts payable, the carrying amounts approximate fair value due to their short
maturities. The estimated fair value of the Company's convertible subordinated
notes and forward exchange contracts was $190 million and $8 million,
respectively, at March 31, 1998. The estimated fair values of the convertible
subordinated notes and forward exchange contracts are primarily based on quoted
market prices.

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.

CHANGE IN ACCOUNTING POLICY FOR BUSINESS PROCESS REENGINEERING COSTS

On November 20, 1997, the Emerging Issues Task Force ("EITF") of the Financial
Accounting Standards Board issued EITF 97-13 "Accounting for Costs Incurred in
Connection with a Consulting Contract that Combines Business Process
Reengineering and Information Technology Transformation." EITF 97-13 requires
that business process reengineering costs incurred in connection with an overall
information technology transformation project be expensed as incurred. The
transition provisions of EITF 97-13 require that companies that had previously
capitalized such business process reengineering costs charge off any unamortized
amounts as a cumulative effect of a change in accounting principle. The
cumulative effect of the change to the Company was to decrease net income by $9
million (net of tax benefit of $3 million).

Pro forma amounts assuming the new accounting principle was applied during all
periods presented follow with comparison to actual amounts reported:

PRODUCT DEVELOPMENT COSTS

The Company's policy is to capitalize internal software development costs
incurred after technological feasibility has been demonstrated. Such internal
software development costs have not been capitalized to date since they were
immaterial.

IMPAIRMENT OF OTHER ASSETS

The Company's other assets include goodwill and minority investments. Goodwill
and minority investments are evaluated periodically for potential impairment
based on the future estimated cash flows of the acquired technology/investment.
Goodwill amortization totaling $9 million, $8 million and $2 million was
included in the Company's consolidated statements of operations during 1998,
1997 and 1996, respectively.

REVENUE RECOGNITION

The Company recognizes revenue upon satisfaction of contractual obligations
which is generally at the time of shipment. The Company records provisions for
estimated returns and allowances at the time of sale.

STOCK-BASED COMPENSATION

The Company accounts for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees." The Company's policy is to grant options with an
exercise price equal to the quoted market price of the Company's stock on the
grant date. Accordingly, no compensation cost has been recognized in the
Company's consolidated statements of operations. The Company has provided
additional pro forma disclosures as required under Statement of Financial
Accounting Standards No. 123 ("SFAS 123"), "Accounting for Stock-Based
Compensation."

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive
Income," which establishes standards for reporting and displaying comprehensive
income and its components in a full set of general-purpose statements. The
disclosure requirements of SFAS 130 are first expected to be reflected in the
Company's first quarter of fiscal 1999 interim statements. In June 1997, the
FASB issued SFAS No. 131 ("SFAS 131"), "Disclosures about Segments of an
Enterprise and Related Information," which establishes annual and interim
reporting standards for an enterprise's business segments and related
disclosures about its products, services, geographic areas, and major customers.
SFAS 131 will be first reflected in the Company's fiscal 1999 Annual Report.
Adoption of SFAS 130 and SFAS 131 will not impact the Company's consolidated
financial position, results of operations or cash flows.

In October 1997, the American Institute of Certified Public Accountants'
("AICPA") issued Statement of Position ("SOP") 97-2 "Software Revenue
Recognition." This SOP supersedes SOP 91-1 "Software Revenue Recognition" and
provides more stringent guidelines for revenue recognition. Adoption of this
statement is not expected to have a material effect on the Company's
consolidated financial position, results of operations or cash flows.

NOTE 2.  NET INCOME PER SHARE

Basic net income per share is computed by dividing net income available to
common stockholders (numerator) by the weighted average number of common shares
outstanding (denominator) during the period and excludes the dilutive effect of
stock options. Diluted net income per share gives effect to all dilutive
potential common shares outstanding during a period. In computing Diluted net
income per share, the average stock price for the period is used in determining
the number of shares to be purchased from exercise of stock options. All prior
period net income per share data presented has been restated in accordance with
SFAS 128.

Following is a reconciliation of the numerators and denominators of the Basic
and Diluted net income per share computations for the years ended March 31:

The conversion of 4,452,000 shares of common stock related to the Convertible
Subordinated Notes was not included in the computation of Diluted net income per
share for the year ended March 31, 1998 as the impact is anti-dilutive.

Options to purchase 2,369,000, 203,000 and 619,000 shares of common stock were
outstanding at March 31, 1998, 1997 and 1996 respectively, but were not included
in the computation of Diluted net income per share because the options' exercise
price was greater than the average market price of the common shares.

NOTE 3.  ACQUISITIONS

In February 1998, the Company entered into an agreement to purchase all of the
outstanding stock of Symbios, Inc. ("Symbios"), a wholly owned subsidiary of
Hyundai Electronics America for approximately $768 million. Symbios is a
supplier of SCSI devices, OEM storage systems and ASIC solutions. In March 1998,
the Company entered into an agreement to purchase read channel ASIC technology
from Analog Devices, Inc. ("ADI"). The agreement calls for an initial

<PAGE>   12

cash payment of $34 million, to be followed by subsequent payments totaling $6
million for research and development services during a transition period, and up
to $20 million in royalties based on sales by the Company of products
incorporating the acquired ADI technology. At March 31, 1998, completion of the
Symbios and ADI acquisitions were subject to regulatory approval under the
Hart-Scott-Rodino Act. Both acquisitions will be accounted for under the
purchase accounting method. The Company will evaluate the allocation of the
purchase price to assets acquired, which include in-process technology that will
be written off, and goodwill which will be amortized over the respective benefit
periods.

During fiscal 1997, the Company acquired complementary businesses and
technologies consisting of Western Digital's Connectivity Solutions Group, CD-R
software technology from Corel, Inc., Data Kinesis, Inc., Sigmax Technology,
Inc., Toast CD-R technology, and certain assets from Skipstone, Inc. for an
aggregate amount of approximately $109 million in cash and $15 million in stock.
These companies design and develop silicon solutions for the SCSI disk drive
market, CD creator for the CD-R software market, software for improving system
performance in file management and RAID applications, CD-ROM controllers for
ATAPI CD-ROM drivers and, CD-R technology for Macintosh platforms. During fiscal
1996, the Company acquired all of the outstanding capital stock of Future Domain
Corporation, Power I/O, Inc., Trillium Research, Inc., and Incat Systems
Software USA, Inc. for an aggregate amount of approximately $35 million in cash
and $17 million in stock.

The Company accounted for these acquisitions using the purchase method of
accounting, and excluding the aggregate $90 million and $52 million write-offs
of acquired in-process technology from these acquisitions for fiscal 1997 and
1996, respectively, the aggregate impact for the respective fiscal year on the
Company's consolidated statements of operations from the acquisition date was
not material. The accounting for the write-off changed in fiscal 1997 due to an
interpretation of SFAS 109 that the Company adopted upon its issuance. In fiscal
1996, the Company was allowed to gross-up the acquired in-process technology and
record a dollar-for-dollar credit through its tax provision.

The allocation of the Company's aggregate purchase price to the tangible and
identifiable intangible assets acquired and liabilities assumed was based
primarily on independent appraisals and estimates of fair value and is
summarized as follows:

</TABLE>

The tangible assets acquired were primarily comprised of inventory and
equipment. Acquired in-process technology was written off in the periods in
which the acquisitions were completed, and the goodwill is being amortized over
respective benefit periods ranging from two to five years.

On August 12, 1996, the Company completed its acquisition of Cogent Data
Technologies, Inc. ("Cogent"). The Company acquired all of the outstanding
capital stock of Cogent in exchange for approximately 3 million shares of its
common stock. Additionally, the Company incurred $2 million in professional fees
related to this acquisition which were included in "write-off of acquired
in-process technology and other." The Company recorded this acquisition using
the pooling of interests method of accounting. Cogent's historical operations,
net assets, and cash flows were not material to the Company's consolidated
financial statements and, therefore, were not reflected in the Company's
consolidated financial results prior to the acquisition. Beginning at the date
of acquisition, the book value of the acquired assets and assumed liabilities as
well as the results of Cogent's operations and cash flows, all of which were not
material to the Company were combined with those of the Company.

The Company has available an unsecured $17 million revolving line of credit
which expires on December 31, 1998. As of March 31, 1998, no borrowings were

entitled at any time on or after May 5, 1997 through February 1, 2004 to convert
the notes into common stock at a conversion price of $51.66 per share. The notes
are redeemable, in whole or in part, at the option of the Company, at any time
on or after February 3, 2000 at declining premiums to par. Debt issuance costs

of $850,000. All outstanding principal and accrued but unpaid interest is due

The Company has authorized 5,600,000 shares of common stock for issuance under
the 1986 Employee Stock Purchase Plan (1986 Plan). Qualified employees 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, 359,849 and 285,336 shares were issued during fiscal

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 of the underlying common stock 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 quarterly and over a one year
period. Upon joining the board, each new non-employee director receives an
option for 40,000 shares which vests over four years. Prior to March 31, 1997,
annual grants vested over a four year period. All options granted prior to March
31, 1997 expire five years after the date of grant, whereas all subsequent
grants expire ten years after the date of grant.

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

PRO FORMA INFORMATION

Pro forma information regarding net income and earnings per share is required to
be determined as if the Company had accounted for its Employee Purchase Plan,
1990 Stock Plan, and 1990 Directors' Option Plan, collectively called "options"
under the fair value method of SFAS 123. The fair value of options granted in
fiscal 1997 and fiscal 1998 reported below has been estimated at the date of
grant using a Black-Scholes option pricing model with the following weighted
average assumptions:

</TABLE>

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options that have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions, including the expected stock price volatility. Because
the Company's options have characteristics significantly different from those of
traded options, and because changes in the subjective input assumptions can
materially affect the fair value estimate, in the opinion of management, the
existing models do not necessarily provide a reliable single measure of fair
value of its options. The weighted average estimated fair value of Employee
Stock Purchase Plan grants during 1998, 1997 and 1996 was $6.84, $6.65 and $4.46
per share, respectively. The weighted average estimated fair value of shares
granted under the 1990 Stock Plan during 1998, 1997 and 1996 was $18.44, $12.24
and $8.95, respectively. The weighted average estimated fair value of shares
granted under the 1990 Directors' Plan during 1998, 1997 and 1996 was $13.56,
$14.80 and $9.81, respectively.

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the options' vesting period. The Company's pro
forma information follows (in thousands except for earnings per share
information):

Pro forma Diluted net income per share      $   1.08      $  0 .72      $   0.90
</TABLE>

The effects on pro forma disclosures of applying SFAS 123 are not likely to be
representative of the effects on pro forma disclosures of future years, since it
is applicable only to options granted subsequent to March 31, 1995. The pro
forma effect of SFAS 123 will not be fully reflected until fiscal 1999.

REPRICING OF STOCK OPTIONS

During the fourth quarter of fiscal 1998, the Company approved the cancellation
and reissuance of outstanding options under the Company's stock option plans.
Under the program, holders of outstanding options with exercise prices in excess
of $22.31 per share were given the choice of retaining these options or of
obtaining in substitution new options for the same number of shares. The new
options are exercisable at a price of $22.31 per share, the fair market value of
the common stock on the reissue date. The new options maintain the vesting
schedule established by the canceled option, except that vesting is suspended
for six months while vesting for officers of the Company participating in the
stock repricing is suspended for twelve months.

RIGHTS PLAN

The Company has reserved 250,000 shares of Series A Preferred Stock for issuance
under the 1996 Rights Agreement which was amended and restated as of December 5,
1996. Under this plan, stockholders have received one Preferred Stock Purchase
Right ("Right") for each outstanding share of the Company's common stock. Each
Right will entitle stockholders to 

<PAGE>   19

buy one one-thousandth of a share of Series A Preferred Stock at an exercise
price of $180.00 per right. The Rights 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 $0.01 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%
stockholder 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 $180.00 per share, common stock having a then
current market value of $360.00 per share.

The Series A Preferred Stock purchasable upon exercise of the Rights will not be
redeemable. Each share of Series A Preferred Stock will be entitled to an
aggregate dividend of 1,000 times the dividend declared per common stock. In the
event of liquidation, the holders of the Series A Preferred Stock will be
entitled to a preferential liquidation payment equal to 1,000 times the per
share amount to be distributed to the holders of the common stock. Each share of
Series A Preferred Stock will have 1,000 votes, voting together with the common
stock. In the event of any merger, consolidation or other transaction in which
the common stock are changed or exchanged, each share of Series A Preferred
Stock will be entitled to receive 1,000 times the amount received per common
stock. These rights are protected by customary anti-dilution provisions.

SHARES RESERVED FOR FUTURE ISSUANCE

At March 31, 1998, the Company has reserved the following shares of authorized
but unissued common stock:

STOCK REPURCHASE

In January 1998, the Company's board of directors authorized the purchase of up
to 10 million shares of the Company's common stock in the open market. During
fiscal 1998, the Company repurchased and retired approximately 350,000 shares of
its common stock from the open market for approximately $8 million. The
transactions were recorded as reductions to common stock and additional paid-in
capital.

The Company's effective tax rate for fiscal 1998 was 26% compared to 37% and 25%
for fiscal 1997 and 1996. The Company's fiscal 1997 effective tax rate was 25%
exclusive of the effect of the book write-offs of in-process technology which
are not deductible for tax purposes. In prior years, the tax effect of similar
book write-offs were included in the cost of the purchased technology.

The Company's manufacturing subsidiary in Singapore is currently operating under
a tax holiday. If certain conditions are met, the tax holiday provides that
profits derived from certain products will be exempt from Singapore tax through
fiscal 2006. In addition, profits derived from the Company's remaining products
will be taxed at a lower rate than the Singapore statutory rate of 26%, through
fiscal 1999. As of March 31, 1998, the Company had not accrued income taxes on
$408 million of accumulated undistributed earnings of its Singapore subsidiary,
as these earnings will be reinvested indefinitely.

MAJOR CUSTOMERS

In fiscal 1998 and 1997, no customer accounted for more than 10% of net

revenues.

NOTE 11. COMMITMENTS AND CONTINGENCIES

The Company leases certain office facilities, vehicles, and certain equipment
under operating lease agreements that expire at various dates through fiscal
2009. As of March 31, 1998, the minimum future payments on existing leases
totaled $21 million. Rent expense was approximately $7 million, $6 million, and
$4 million during fiscal 1998, 1997 and 1996, respectively. The Company has a
commitment denominated in Singapore dollars related to the construction of the
Company's manufacturing facility in Singapore. To minimize the foreign currency
exposure related to this commitment, the Company entered into several forward
exchange contracts to purchase 13 million Singapore dollars. The maturities of
these instruments are less than 12 months. Deferred gains or losses are not
material.

During fiscal 1998, 1997, and 1996, the Company entered into agreements with
Taiwan Semiconductor Manufacturing Co., Ltd. ("TSMC") to ensure availability of
a portion of the Company's silicon wafer requirement for both current and future
technologies. The agreement runs through 2001 providing the Company with a
guarantee of increased capacity for wafer fabrication in return for advance
payments totaling $35 million, $15 million and $66 million in fiscal 1998, 1997,
and 1996, respectively. The advance payments that are expected to be utilized in
the next 12 months are classified in prepaid expenses and the remaining advanced
payments are classified in other assets and will be realized by the Company at
specified amounts over the agreement period. In fiscal 1998, the Company signed
a non-interest bearing promissory note for the $35 million advance payment. At
March 31, 1998, $18 million remained outstanding, and is due in June 1998. There
can be no assurance that the Company will be able to satisfy its future wafer
needs from current or alternative manufacturing sources. This could result in
possible loss of sales or reduced margins.

During fiscal 1997, the Company entered into an agreement with Lucent
Technologies, Inc. ("Lucent") to sell $21 million of equipment that it had
previously purchased in connection with a separate agreement that ensured
availability of certain levels of wafer capacity from Lucent. The new agreement
canceled the initial capacity agreement and required Lucent to purchase the
equipment from the Company in fiscal 1998.

Several class action lawsuits have been filed in the United States District
Court for the Northern District of California against the Company and certain of
its officers and directors. The actions all allege that the Company made false
and misleading statements at various times during the period between April 1997
and January 1998 in violation of the federal securities laws. The complaints do
not set forth purported damages. In addition, a number of derivative actions
have been filed in the Superior Court of the State of California against the
Company and certain of its officers and directors alleging that the individual
defendants improperly profited from transactions in the Company's stock during
the same time period referenced by the class action lawsuits. The Company
believes the lawsuits and derivative actions are without merit and intends to
defend itself vigorously.

The IRS is currently auditing the Company's income tax returns for fiscal 1994
to 1996. No proposed adjustments have been received for these years. The Company
believes sufficient taxes have been provided in prior years and that the
ultimate outcome of the IRS audits will not have a material adverse impact on
the Company's financial position or results of operations.

NOTE 12. RELATED PARTY TRANSACTIONS AND SUBSEQUENT EVENTS

During fiscal 1998, the Company invested $5 million in Series A Preferred Stock
representing a 19.9% interest in Ridge Technologies ("Ridge" ). In conjunction
with this investment, the Chairman and CEO of the Company became a director of
Ridge. During fiscal 1998, the Company incurred $900,000 in research and
development expenditures related to consulting services provided by Ridge. In
February 1998, the Company guaranteed a $7 million line of credit on behalf of
Ridge in exchange for a warrant to purchase up to 200,000 shares of Ridge common
stock. On May 21, 1998, the Company acquired Ridge in a stock transaction valued
at approximately $21 million and assumed stock options valued at approximately
$13 million.

The Chairman and CEO of the Company is a director of Analog Devices, Inc.
("ADI"). In April 1998, the Company received regulatory approval to purchase
read channel ASIC technology from ADI (see Note 3).

During fiscal 1998, the Company invested $1 million in, and entered into a
development and license agreement with, a venture stage company whose founder
and CEO is a director of the Company. Two other directors of the Company are
also directors of the start up company.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Adaptec, Inc.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of cash flows and of stockholders' equity
present fairly, in all material respects, the financial position of Adaptec,
Inc. and its subsidiaries at March 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
March 31, 1998, 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 audits. We conducted our audits 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 our audits provide a reasonable basis for the opinion expressed above.

As discussed in Note 1 to the consolidated financial statements, the Company
changed its method of accounting for business process reengineering costs in
1998.

the Company made false and misleading statements at various time during the

securities laws. The complaints do not set forth purported damages. The Company
believes the lawsuits are without merit and intends to defend itself vigorously.
