System Software

The system software environment is a key component for fulfilling customer
needs around the network. The Company continues to focus on providing
customer-centric solutions, including the Solaris operating environment with
built-in networking, WorkShop tools for building network applications, and
Solstice software that connects it all together and manages the entire computing
enterprise. The Company believes it derives competitive advantage from the
stability resulting from its many years of experience with operating system
software. The Company's principal software products are as follows:

Solaris Operating Environment - Solaris products include desktop,
intranet, ISP and enterprise operating environments for SPARC and Intel
platforms. Solaris is a fast, highly reliable, scaleable and secure operating
environment, easy to install and use, optimized for Java and supports more than
12,000 applications. The Solaris environment is optimized for corporate

Network Management Products - The Company's principal enterprise
computing management solution, Sun Network Management Products (Solstice)
provide a comprehensive suite of system and network management tools and
applications that give network managers the flexibility of distributed computing
with the control of centralized management for workgroups, departments, or the
enterprise - regardless of the vendors or operating systems comprising their
network. Solstice utilizes distributed computing technologies to scale and
manage global heterogeneous networks, such as those in telecommunications and
financial services companies. Solstice products such as Enterprise Manager
decrease the complexity of managing enterprise-wide networks while significantly
lowering the total cost of operation.

Sun Network Management Products are central to Sun's open systems
architecture. These products provide networking capabilities that make
distributed resources easily accessible by PCs, workstations, servers and other
computing devices on a single network. These products also integrate
heterogeneous global, department, local and remote network resources into
company-wide information systems. The Company is committed to developing
networking products that adhere to and promote open industry networking
standards and technologies in emerging areas such as the Internet and intranet.

In addition, Sun Internet Mail Server software helps companies consolidate
their business on a single, scaleable e-mail architecture, enabling open,
reliable, and cost-effective communication. Built on Internet and industry
standards such as SMTP and MIME, Sun Internet Mail Server offers a single, open
Internet alternative to proprietary mail systems. Sun Internet Mail Server
provides the industry's most complete implementation of the latest Internet
standard, Internet Message Access Protocol version 4 (IMAP4), for reliable mail
messaging.

Network Security Solutions - Sun provides businesses with a
comprehensive set of modular, heterogeneous, and scaleable security solutions

OpenStep, PASCAL and MicroFocus COBOL. Java Workshop is a powerful and
streamlined Internet programming environment allowing developers to create and
publish Internet applications. Visual Workshop for C++ provides a tightly
integrated visual programming environment for professional developers to build
and deploy high-performance client-server applications. Internet Workshop also
offers tools for developing object-oriented, three-tier networked applications
with Java, C++ and the NEO CORBA-compliant IDL.

The Java Developers Kit enables developers to create Java applets,
which are miniature applications that run inside a World Wide Web page, as well
as Java applications.

JavaSoft Products - The Java Application Environment (JAE) is one of
the first widely accepted application environments to enable the platform -
independent development of application software. In fiscal 1997, Sun licensed
JAE and JavaOS to over thirty computer and software companies, including several
high volume operating system vendors. These vendors plan to integrate JAE into
their operating systems so that applications written in Java will run on their
systems. In addition, the Company initiated a range of development activities
during fiscal 1997 to increase the capabilities of the Java language.

Sales, Distribution and Marketing

Sun maintains a presence in most major markets and sells computer systems,
software and services to its customers worldwide through a combination of direct
and indirect channels. The Company also offers off-the-shelf software and
component products such as CPU chips, ASICs and embedded boards on an OEM basis
to other hardware manufacturers, and supplies after-market and peripheral
products to its end user installed base, both directly and through independent
distributors and resellers.

In general, the Company's direct sales force is compensated on a
channel-neutral basis to reduce potential channel conflict with our distribution
partners. Distribution channels include:

- a direct sales force selling to selected end-user named accounts and
numerous indirect channels,

- systems integrators, both government and commercial, who serve the
market for large commercial projects requiring substantial analysis,
design, development, implementation and support of custom solutions;

- master resellers who supply product and provide product marketing
and technical support services to the Company's smaller Value Added
Resellers ("VARs");

- VARs who provide added value in the form of software packages,
proprietary software development, high-end networking integration,
vertical integration, vertical industry expertise, training,
installation and support;

- OEMs who integrate the Company's products with other hardware and
software; and

- independent distributors who primarily cover markets in which Sun
does not have a direct presence.

The growth and management of the reseller channels is very important to the
future revenues and profitability of the Company. Channel partners account for
greater than 50% of Sun's revenue today and will continue to play a key role in
providing the value, service and support that are critical to Sun's long term
success.

The Company's direct systems sales force serves educational institutions,
software vendors, governments, businesses and other strategic accounts. The
Company has approximately 80 sales and service offices in the United States and
approximately 88 sales and service offices in 40 other countries. In addition,
it uses independent distributors in approximately 150 countries, sometimes in
concert with other resellers and direct sales operations.

Revenues from outside the United States, including those from end users,
resellers and distributors, constituted approximately 49% in fiscal 1997 and 50%
of net revenues in fiscal 1996, and 1995. Direct sales made in countries outside
of the United States are generally priced in local currencies and are,
therefore, subject to currency exchange fluctuations. The net impact of currency
fluctuations on net revenues and operating results cannot be precisely measured
as the Company's product mix and pricing change over time in various markets,
partially in response to currency movements. To minimize currency exposure gains
and losses, the Company borrows funds in local currencies, enters into forward
exchange contracts, purchases foreign currency options and promotes natural
hedges by purchasing components and incurring expenses in local currencies
whenever feasible. Sun's sales to overseas customers are made under export
licenses that must be obtained from the United States Department of Commerce.
Protectionist trade legislation in either the United States or other countries,
such as a change in the current tariff structures, export compliance laws or
other trade policies, could adversely affect Sun's ability to sell or to
manufacture in international markets. Sales to or through C. Itoh Technoscience
Co. Ltd., Fujitsu, Ltd. and Toshiba Corporation together represent a significant
portion of Sun's revenues in Japan. See Note 9 of Notes to Consolidated
Financial Statements incorporated by reference herein for additional information
concerning sales to foreign customers and industry segments.

Seasonality affects the Company's revenues and operating results,
particularly in the first and third quarter of each fiscal year. In addition,
the Company's operating expenses are increasing as the Company continues to
expand its operations, and future operating results will be adversely affected
if revenues do not increase proportionatly with such increased expense levels.

The Company's marketing activities include advertising in computer
publications and the business press, direct mailings to customers and prospects,
televised programs and attendance at trade shows.

Sun maintains a customer resource program, Sunergy(TM), which includes live
interactive satellite broadcasts and provides electronic access to newsletter
and technical information. Sun also sponsors a series of seminars to specific
resellers, university customers, end users and government customers and
prospects designed to familiarize attendees with the capabilities of the Sun
product line.

Sun's order backlog at June 30, 1997 was approximately $378 million,
compared with approximately $522 million at June 30, 1996. Backlog includes only
orders for which a delivery schedule within six months has been specified by the
customer. Backlog levels vary with demand, product availability and the
Company's delivery lead times and are subject to significant decreases as a
result of, among other things, customer order delays, changes or cancellations.
As such, backlog levels are not a reliable indicator of future operating
results.

Customer Service and Support

The Company provides expertise in heterogeneous network computing through a full
range of global services, including support services (hardware and software
systems support), educational services (education consulting, skills migration
and training) and professional services (IT consulting, systems integration and
system/network management). Sun assists both technical and commercial customers,
supporting more than 700,000 systems in 170 countries, training more than 75,000
students annually, and providing consulting, integration and operations
assistance to IT organizations worldwide.

In support services, Sun has increased field resources in direct service
delivery, especially software support engineers based in solution centers and
field offices. Higher levels of field resources are critical to the overall
investments being made in mission-critical support capability. This direct Sun
capability is complemented by third-party service providers who primarily
deliver hardware support services. Software support continues to be primarily
delivered by Sun software support engineers. Third party service providers
provide necessary leverage on critical field resources such as parts inventories
and staff to meet the service requirements of the growing installed base.
Investments by these third-party service providers in complementary support
infrastructure facilitates expansion of geographical coverage without additional
fixed cost investment by the Company.

The Company offers a warranty for parts and labor on its hardware products
generally for one year from date of sale and a limited warranty on software
generally for 90 days from date of sale. The Company maintains and services the
products during the warranty period and on a contractual basis after the initial
product warranty has expired. Post-warranty support services are primarily
offered through a tiered support offering called SunSpectrum(TM). SunSpectrum
offers four levels of differentiated support that package hardware, software and
peripherals in a single price support service. Warranty and post-warranty
services are provided through 27 solution centers worldwide.

Sun's educational services offers comprehensive skills migration, enterprise
consulting and courseware. Consultants can perform needs analysis, skills
assessment and migration, curriculum design and course customization.
Instructor-led courseware addresses the educational needs of many customers
including managers, operators, developers, system administrators, and end-users.
As an alternative to the classroom, customers may select self-study training,
including more than 50 interactive training products geared for all levels of
expertise.

In professional services, Sun provides the people, processes and technology to
deliver single point-of-contact solutions tailored to meet customer needs. Sun
technical and project management experts help customers plan, implement, and
manage heterogeneous computing environments. Sun consultants also help design IT
architectures and plan migrations from legacy systems to network computing. To
implement solutions, integration experts help customers develop and deploy
distributed computing environments for new applications. To keep the environment
operating at peak performance, operations experts help customers manage the
complexity of the heterogeneous systems and networks. In addition, Sun helps
with all phases of creating and implementing internet solutions. Investments
have been made in competencies in Internet/Java, business applications and
systems and network management.

Certain complex systems sold by Sun require a high level of implementation
support and consequently, the customer's acceptance of such systems may be
delayed in the event Sun does not provide a sufficient level of such service.
Delays in customer acceptance could adversely affect the future operating
results of the Company.

Product Development

The Company's research and product development programs are intended to
sustain and enhance its competitive position by incorporating the latest
worldwide advances in hardware, software, graphics, networking, data
communications and storage technologies. Sun's product development

6


efforts, conducted within each of its businesses, are currently focused on
enhancing its products' performance and price/performance, as well as
reliability, availability, and serviceability, of both the Company's hardware
and systems software for the Company's expanding enterprise client-server
computing customer base. Additionally, Sun remains focused on system software
platforms for Internet and intranet applications, developing advanced
workstation and server architectures, designing application-specific integrated
circuits and software for networking and distributed computing. Sun product
development continues to be committed to including the high-performance
implementation of existing standards and the development of new technology
standards.

Sun conducts research and development worldwide principally through
facilities in the United States, France, and Japan. Research and development
expenses were approximately $826 million, $653 million and $563 million in
fiscal 1997, 1996 and 1995, respectively. In recent years, Sun's research and
development efforts have focused increasingly on the Java architecture, Solaris
software and SPARC microprocessors. Sun believes that software development
provides and continues to provide significant competitive differentiation.
Therefore, Sun currently devotes substantial resources to the development of
workgroup software, networking and data communications, video, graphics, disk
array, object technology and the software development environment.

The development of high performance computer products is a complex and
uncertain process requiring high levels of innovation from the Company's
designers and suppliers, as well as accurate anticipation of customer
requirements and technological trends.

Manufacturing and Supply

The Company's manufacturing operations consist primarily of printed circuit
board assembly and final assembly, test and quality control of systems,
materials and components. Sun has manufacturing facilities in California,
Oregon, England and Scotland, and distribution facilities in California, the
Netherlands and Japan. The Company has continued its efforts to simplify its
manufacturing process by reducing the diversity of system configurations offered
to customers, increasing the standardization of components across product types
and establishing local sources of supply in major geographies.

Sun uses many standard parts and components in its products and believes
there are a number of competent vendors for most parts and components. However,
a number of important components are developed by and purchased from single
sources due to price, quality, technology or other considerations. In some
cases, those components are available only from single sources. In particular,
Sun is dependent on Sony Corporation for various monitors and on Fujitsu Limited
(Fujitsu) and Texas Instruments Incorporated for different implementations of
SPARC microprocessors. Certain custom silicon parts are designed by and produced
on a contractual basis for Sun. The process of substituting a new producer of
such parts could adversely affect Sun's operating results. Some suppliers of
certain components, including color monitors and custom silicon parts, require
long lead times such that it can be difficult for the Company to plan inventory
levels of components to consistently meet demand for Sun's products. Certain
other components, especially memory integrated circuits such as DRAMs, SRAMs,
and VRAMs, have from time to time been subject to industry wide shortages.
Future shortages of components could negatively affect the Company's ability to
match supply and demand, and therefore could adversely impact the Company's
future operating results.

The Company is increasingly dependent on the ability of its suppliers to
design, manufacture and deliver advanced components required for the timely
introduction of new products. The failure of any of these suppliers to deliver
components on time or in sufficient quantities, or the failure of any of the
Company's own designers to develop advanced innovative products on a timely
basis, could result in a significant adverse impact on the Company's operating
results. The inability to secure enough components to build products, including
new products, in the quantities and configurations required, or to produce, test
and deliver sufficient products to meet demand in a timely manner, would
adversely affect the company's net revenues and operating results.

To secure components for development, production and introduction of new
products, the Company frequently makes advanced payments to certain suppliers
and often enters into noncancelable purchase commitments with vendors early in
the design process. Due to the variability of material requirement
specifications during the design process, the Company must closely manage
material purchase commitments and respective delivery schedules. In the event of
a delay or flaw in the design process, the Company's operating results could be
adversely affected due to the company's obligations to fulfill such
noncancelable purchase commitments. Once a hardware product is developed the
Company must rapidly bring it to volume manufacturing, a process that requires
accurate forecasting of both volumes and configurations, among other things, in
order to achieve acceptable yields and costs. Upon introduction of new products,
the Company must also manage the transition from older, displaced products to
minimize disruptions in customer ordering patterns, reduce levels of older
product inventory, and ensure that adequate supplies of new products can be
delivered to meet

7


customer demand. The ability of the Company to match supply and demand is
further complicated by the need to take pricing actions and the variability of
timing of customer orders. As a result, the Company's operating results could be
adversely affected if the Company is not able to correctly anticipate the level
of demand for the mix of products. Because the Company is continuously engaged
in this product development, introduction, and transition process, its operating
results may be subject to considerable fluctuation, particularly when measured
on a quarterly basis.

The computer systems offered by Sun generally are the result of both
hardware and software development, so that delays in software development can
delay the Company's ability to ship new hardware products. Adoption of a new
release of an operating system may require effort on the part of the customer as
well as software porting by software vendors providing applications. As a
result, the timing of conversion to a new release is inherently unpredictable.
Moreover, delays in adoption of a new release of an operating system by
customers can limit the acceptability of hardware products tied to that release.
In either situation, the future operating results of the Company could be
adversely affected.

Competition

The market for the Company's products and services is intensely competitive
and subject to continuous, rapid technological change, short product life cycles
and frequent product performance improvements and price reductions. Due to the
breadth of Sun's product line and the scalability of its products and network
computing model, the Company competes in many segments of the computer market
across a broad spectrum of customers. The requirements of those customers and
the basis of competition varies widely depending on the market segment and types
of users.

Sun's traditional customer base has been in the technical and scientific
markets. Competition in this segment is based primarily on system performance,
price/performance, availability and performance of application software,
robustness of the software development environment, system expandability and
upgradeability, adherence to standards, graphics features and performance and
product quality and reliability. Increasingly, Sun is finding that its strengths
in technical markets, particularly software development, design automation and
decision support, along with its network computing focus are enabling expansion
into mission critical enterprise applications. Sun's competitors in the
technical and scientific markets are primarily Hewlett-Packard Company (HP),
International Business Machines Corporation (IBM), Digital Equipment Corporation
(DEC) and Silicon Graphics, Inc. (SGI).

Sun has been making inroads into commercial markets both with Global 1000
companies which are downsizing and distributing their computer resources, as
well as with smaller companies which are upsizing and increasing the
capabilities of their network computing systems. Traditionally, competition in
these markets has been based on price/performance, capabilities and stability of
the systems software, product quality and reliability, ease of system operation
and administration, service and support, availability and performance of
applications and middleware, database performance, global marketing and
distribution capabilities, and corporate reputation and name recognition.
Increasingly, companies which are downsizing their operations are focusing on
distributing their computing capabilities and adopting a model of network
computing. Companies which are upsizing typically are increasing their
experience in managing larger heterogeneous environments. In addition, Sun is
continuing to expand into the Internet and intranet markets. As a result, in
both the upsizing and downsizing competitive scenarios, networking capabilities,
internet and intranet capabilities and the ability to obtain all of the
traditional security, stability and administrative features of a central
computing model in a networked environment are significant factors that
influence the buying decision and the relative strength of the competition. In
both upsizing and downsizing opportunities, Sun's competition tends to come
principally from IBM, HP, and DEC, as well as other mini and mainframe computer
suppliers. In addition, the Company is facing increasing competition from these
competitors as well as from personal computer manufacturers such as Compaq
Computer Corporation and Dell Computer Corporation, with respect to products
based on microprocessors from Intel Corporation coupled with Windows NT
operating system software from Microsoft Corporation. These products demonstrate
the viability of certain networked personal computer solutions and have
increased the competitive pressure, particularly in the Company's workstation
and lower-end server product lines.

Sun has also encouraged the proliferation of its SPARC technology as a
standard in the computer marketplace by licensing much of the technology and
promoting open interfaces to the Solaris operating environment, as well as by
offering microprocessors and enabling technologies to third party customers. As
a result, several licensees also offer SPARC/Solaris based products that compete
directly with Sun's products primarily in the desktop markets.

The Company expects that the markets for its products, technology and
services as well as its competitors within such markets, will continue to change
as the combination of these downsizing and

8


upsizing trends shift customer buying patterns to network centric employing
multiple platform networks. Competition in these markets will also continue to
intensify as Sun and its competitors aggressively position themselves to benefit
from this shifting of customer buying patterns and demand. The ability to
continue to develop leading edge products and rapidly bring them to market will
continue to have a significant impact on Sun's competitiveness and its operating
results. In addition, Sun expects to see continued performance improvements in
microprocessor technology and products introduced by Intel and Motorola, Inc.
Such products, coupled with enhanced operating systems software from Microsoft
and other competitors, are expected to continue to provide competitive pressure
throughout the Company's product range. The Company expects this pressure to
continue to intensify in fiscal 1998 with the availability of Pentium Pro
systems running Windows NT server software. While many other technical, service
and support capabilities affect a customer's buying decision, Sun's future
operating results will depend, in part, on its ability to compete with these
technologies.

In order to remain competitive in a rapidly changing industry, the Company
is continually improving and changing its business practices, processes and
information systems. In this regard, the Company has begun to implement a number
of new business practices and a series of related information systems; such
activities are currently planned to be fully operational in the first half of
fiscal 1999. Implementing a number of new business practices and information
systems is a complex process, affecting numerous operational and financial
systems and processes as well as requiring comprehensive employee training.
While the Company tests these new systems and processes in advance of
implementation, there are inherent limitations in the Company's ability to
simulate a full-scale operating environment in advance of system cutover. To the
extent that the Company encounters problems after introduction of these new
systems and practices that prevent or limit their full utilization, there could
be a material, adverse impact on the Company's results.

Patents and Licenses

Sun currently holds a number of U.S. and foreign patents relating to
various aspects of its products and technology. While the Company believes that
such patent protection is important, it also believes that patents are of less
competitive significance than such factors as innovative skills and
technological expertise.

As is common in the computer industry, the Company has from time to time
been notified that it may be infringing certain patents and other intellectual
property rights of others, although no material litigation has arisen out of any
of these claims. Several pending claims are in various stages of evaluation. The
Company is evaluating the desirability of entering into licensing agreements in
certain of these cases. Based on industry practice, the Company believes that in
most cases any necessary licenses or other rights could be obtained on
commercially reasonable terms. However, no assurance can be given that licenses
can be obtained on acceptable terms or that litigation will not occur. The
failure to obtain necessary licenses or other rights, or litigation arising out
of such claims, could have a material adverse effect on the Company's
operations.

Sun has entered into separate patent exchange agreements with IBM, Cray
Research, Inc. (Cray) and Fujitsu. Under each agreement, the parties have
granted to each other non-exclusive, worldwide rights to patents in their
respective patent portfolios. These agreements cover patents issued or applied
for during certain limited periods as specified in the agreements. The
agreements with Cray and Fujitsu are royalty free. The agreement with IBM
expired at the end of fiscal 1995 and the licenses to the patents thereunder do
not apply to the patents of IBM or the Company applied for after that date.

In March 1990, Texas Instruments Incorporated (TI) alleged that a
substantial number of the Company's products infringe certain of TI's patents.
Based on its discussions with TI, the Company believes that it will be able to
negotiate a license agreement with TI, if necessary, and that the outcome of
this matter will not have a material adverse effect on Sun's financial position
or its results of operations or cash flows in any given fiscal year. Such a
negotiated license may or may not have a material adverse impact on Sun's
results of operations or cash flows in a given fiscal quarter depending upon
various factors including, but not limited to, the structure and amount of
royalty payments, offsetting consideration from TI, if any, and the allocation
of royalties between past and future product shipments, none of which can be
forecast with reasonable certainty at this time.

Employees

9


As of June 30, 1997, Sun employed approximately 21,500 people. The
Company's future operating results will depend on its ability to continue to
broaden and develop senior management to attract and retain skilled employees,
and on the ability of its management and key employees to manage growth
successfully through the enhancement of management information systems and
financial controls. The Company expects to continue to increase its number of
employees to support demand creation programs, service and support operations,
and overall projected growth. None of Sun's employees in the United States are
represented by a labor union.

ITEM 2. PROPERTIES

Sun conducts its worldwide operations using a combination of leased and
owned facilities. The Company believes that while it currently has sufficient
facilities to conduct its operations during fiscal 1998, it will continue to
lease and acquire owned facilities throughout the world as its business
requires. Properties owned by the Company consist of an approximately 260,000
square foot facility on approximately 20 acres in Palo Alto, California; an
approximately 227,000 square foot facility on approximately 30 acres in
Linlithgow, Scotland; an approximately 30,000 square foot facility on
approximately 2.5 acres in Bagshot, England; 40 acres in Farnborough England;
two separate parcels of land in Newark, California of approximately 90 acres and
60 acres, approximately 1,000,000 square feet on approximately 55 acres in Menlo
Park, California; approximately 120 acres in Broomfield, Colorado; and
approximately 158 acres in Burlington, Massachusetts. Sun also plans on
acquiring an approximately 82 acre site in Santa Clara, California and an
additional 48 acre site in Newark, California. The Company has approved the
construction of an approximately 525,000 square foot facility on one of its Bay
Area sites, an approximately 500,000 square feet facility on its Broomfield,
Colorado site, an approximately 475,000 square feet facility on its Burlington,
Massachusetts site and approximately 225,000 square foot manufacturing facility
on one of its Newark, California parcels. Total cost for these facilities are
expected to be approximately $300 to $600 million. Sun leases approximately 230
sales and service offices throughout the world aggregating about 3 million
square feet. Sun also leases approximately 3 million square feet for its
research and development and manufacturing facilities, primary in Milpitas,
Sunnyvale, San Jose and Mountain View, California and Chelmsford, Massachusetts.
Sun's California manufacturing plant, the majority of its research and
development facilities, its Corporate headquarters and other critical business
operations are located near major earthquake faults. Operating results could be
materially adversely impacted in the event of a major earthquake.
