GENERAL

We are a leading worldwide provider of products, services and support
solutions for building and maintaining network computing environments. We sell
scalable computer systems, high-speed microprocessors, and a complete line of
high performance software for operating network computing equipment and storage
products. We also provide a full range of services, including support,
education, and professional services. Our products and services command a
significant share of the rapidly growing network computing market, which
includes the Internet and corporate intranets. Our products are used for many
demanding commercial and technical applications in various industries including
telecommunications, manufacturing, financial services, education, retail,
government, energy and healthcare. We owe much of our success to our adherence
to open industry standards, the Solaris(TM)Operating Environment, the UNIX(R)
platform, and the UltraSPARC(TM) (Ultra Scalable Processor Architecture)
microprocessor architecture. In addition we are committed to investment in and
ownership of intellectual property, leveraging our partnerships with industry
leaders and enabling the Internet and the "Net Economy."

For the latest fiscal year ended June 30, 1999, we had annual revenues of
more than $11.7 billion, over 29,000 employees, and we conducted business in
over 170 countries. We were incorporated in California in February, 1982 and
reincorporated in Delaware in July, 1987.

BUSINESS STRATEGY

Our objective is to expand our position as a leading global provider of
network computing products and services. The key elements of our strategy
include:

- developing network computing products and technologies that enable the
Internet and the Net Economy

- providing competitive solutions based on open industry standards

- extending our technology leadership and innovation

- investing in support, education and professional services

- leveraging strong industry relationships

DEVELOPING NETWORK COMPUTING PRODUCTS AND TECHNOLOGIES THAT ENABLE THE INTERNET
AND THE NET ECONOMY

We were founded on the notion that computer networks are greater than the
sum of their parts and that communication and information access should be
uninhibited by the boundaries of proprietary software and

1
3

hardware architectures. To help us explain this vision we coined the phrase,
"The Network is the Computer(TM)," and built networking technologies into every
product. From the Solaris(TM) Operating Environment to UltraSPARC
microprocessors, from scalable servers to the Java(TM) and Jini(TM) platforms,
we are focused on providing customers with a single, high performance, highly
reliable network computing architecture. This single focus provides customers
with investment protection for their legacy computing environments, a single
operating environment that is both backward compatible and scalable across our
entire product line (binary compatibility) and an upgrade path for their entire
network.

The Internet has grown to encompass much more than simple information
sharing. Increasingly, the Internet is enabling a whole new paradigm of business
commerce that brings customers closer to suppliers and streamlines the delivery
of goods and services. This new paradigm is commonly referred to as the Net
Economy and is changing the fundamentals of most every business and industry
across the globe. Through our products and technologies, we are helping
customers participate in the Net Economy by implementing new processes and
practices to take advantage of the opportunities that the Internet can provide.

PROVIDING COMPETITIVE SOLUTIONS BASED ON OPEN INDUSTRY STANDARDS

From inception, we have focused on developing products and technologies
based upon open industry standards to provide customers with flexibility for
their networking environments. Through our commitment to open, industry
standards, we have created technologies, such as Network File System (NFS(TM)),
Scalable Processor Architecture (SPARC(TM)) and most recently Java(TM) and
Jini(TM), that have facilitated industry growth.

Through the Internet, we are realizing our long-standing vision of a
network where information can be accessed at anytime, from anywhere, by anyone
and from any device. The Internet is growing and expanding to be more than just
a repository of information. Increasingly, businesses are looking to the
Internet to enable more effective and efficient methods of electronic commerce
and communication, to streamline business practices, increase productivity and
reduce both costs and complexity. By harnessing the power of the Internet,
businesses are transforming traditional practices and promoting the Net Economy.
We support this transformation by leveraging the power of our computing
technologies in order to provide our customers with the solutions they need to
effectively utilize the power of the Internet.

EXTENDING OUR TECHNOLOGY LEADERSHIP AND INNOVATION

We believe that in order to be a leading developer of enterprise and
Internet-based products and technologies, we must continue to invest and
innovate. Through our research and development investments, which have typically
been approximately 10% of annual revenues, we are continually focusing on
raising the bar of technological innovation. Over the past few years, we have
made significant investments in several of our product technologies, including
our highly scalable UltraSPARC processor architecture, our highly reliable and
scalable Solaris Operating Environment, our cross-platform Java software
development environment powering Internet-based applications, our Java-based
Jini technology that allows a broad range of devices to connect and share
information over the Internet and with one another, our scalable enterprise
servers and workstations, and our network-based storage systems and software.
Many of these technologies provide us with a competitive advantage and
differentiation in the marketplace. We intend to continue our investments into
new computing technologies and are focused on continuing to develop and deliver
leading edge network computing products based upon our innovations.

INVESTING IN SUPPORT, EDUCATION AND PROFESSIONAL SERVICES

We are also investing in the expansion of our support, education and
professional services. As the market for network computing and Internet products
and technologies expands, the demand for services also increases. In recognition
of this demand, we hired nearly 1,700 people in the last fiscal year ended June
30, 1999 into our Enterprise Services organization, which now employs over 7,500
professionals. With a shortage of computing professionals worldwide, our
customers are increasingly demanding support for enterprise as well as Internet
projects. They require key integration, training, support and development
services to bring their

2
4

business processes and practices to the Internet. In addition, customers are
looking for network computing suppliers to provide them with solutions to their
enterprise and Internet computing needs. To meet the needs of our customers and
partners, we will continue to invest in acquiring additional personnel to staff
our rapidly growing support, education and professional services organization.

LEVERAGING STRONG INDUSTRY RELATIONSHIPS

While our product and service offerings are very broad, we recognize that
no single supplier of computing solutions can meet all of the needs of all of
its customers. We have established relationships with leading value-added
resellers, OEMs, service providers, independent software vendors (ISV) and
systems integrators to deliver solutions that customers demand. Through these
relationships, we are able to provide the end-to-end solutions that customers
require to compete in the Net Economy. We also have relationships with leading
network and application service providers, and offer the products, technologies
and services they require for highly reliable applications and networking
services to their customers. These cooperative relationships provide an
attractive business model for these partners and create an environment where Sun
benefits as our partners' businesses grow. In order to foster strong
relationships, we have also instituted sales force incentive and flexible
financing programs that align our operations with the success of their business.

BUSINESS ORGANIZATION

To facilitate innovation and provide world class support for our global
client base, we are structured as a group of businesses, each providing open,
standard products and services for commercial and technical computing.

NETWORK STORAGE

Our Network Storage systems and software also support our strategy of
providing products and technologies to network computing environments. Through
our broad product line, we are able to deliver not only storage connectivity,
but also storage intelligence to the network across multiple operating
environments, including NT.

The Intelligent Storage Server(TM) A7000 offers seamless UNIX/mainframe/NT
information sharing capabilities. It is designed to deliver high-end,
heterogeneous storage supporting UNIX platforms, mainframes and NT platforms and

JAVA. Our Java application environment is one of the first widely accepted
application environments to allow development of application software
independent of the underlying platform. In fiscal 1999, Sun broadly expanded the
definition and availability of the Java platform and extended it to the smallest
devices, such as smart cards, personal digital assistants, and embedded
controllers and set-top boxes with our MicroJava(TM) platform, as well as to the
enterprise with our EnterpriseJava platform. These two new Java platforms
address

6

very different markets, yet share a common core architecture and Application
Programming Interface (API) set. These platforms complement our StandardJava
platform which is intended for PC and workstation clients.

The Java Development Kit enables developers to create and run applets
(which are miniature applications written in the Java programming language) that
run inside a compatible web browser, and full applications written using the
Java programming language.

JINI. Jini connection technology is based upon a single concept, that
devices should work together and simply connect to the network. This means that
there are no drivers to find, no complex proprietary software requirements, and
no cables and connectors that can be difficult to match. There are three Jini
System Software product offerings: the Jini System Software Starter Kit, the
Jini Technology Core Platform Compatibility Kit, and the JavaSpaces(TM)
Technology Kit. These products contain components of the Jini technology to
assist developers in creation of new Jini services.

ENTERPRISE SUPPORT, EDUCATION, AND PROFESSIONAL SERVICES

alliance is uniquely positioned to provide technologies and products that better
support enterprises and service providers. In addition, alliance products
support the Solaris Operating Environment, NT, HP-UX, AIX and Linux.

SALES, DISTRIBUTION AND MARKETING

We maintain a presence in most major markets and sell computer systems,
software and services to our customers worldwide through a combination of direct
and indirect channels. We also offer off-the-shelf software and component
products such as CPU chips, ASICs and embedded boards on an OEM basis to other
hardware manufacturers, and supply after-market and peripheral products to their
end-user installed base, both directly and through independent distributors and
resellers.

7

Our direct sales force is organized into two primary sales forces: a sales
force concentrating on enterprise systems, storage, and some software products
and a sales force for software products and platforms. These sales forces sell
to selected end-user named accounts and numerous indirect channels. Each sales
force is compensated on a channel-neutral basis to reduce potential channel
conflict between distribution partners. Our other distribution channels include:

- 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 our 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 our products with other hardware and software; and

- independent distributors who primarily cover markets in which we do not
have a direct presence.

The growth and management of the reseller channels is very important to our
future revenues and profitability. Channel partners account for more than 50% of
our revenues and will continue to play a key role in providing the value,
service and support critical to our long-term success.

Our direct systems sales force serves educational institutions, software
vendors, governments, businesses and other strategic accounts. We have
approximately 100 sales and service offices in the United States and
approximately 140 sales and service offices in 45 other countries. In addition,
we use independent distributors in approximately 150 countries, sometimes with
other resellers and direct sales operations.

Our revenues from outside the United States, including those from
end-users, resellers and distributors were approximately 49%, 48% and 49% of our
total revenues in fiscal 1999, 1998, and 1997, respectively. If we are unable to
continue generating substantial revenues from international sales our business
could be substantially harmed. Our ability to sell our products internationally
is subject to the following risks:

- general economic and political conditions in each country could adversely
affect demand for our products and services in these markets, as recently
occurred in certain Asian and Latin American markets;

- currency exchange rate fluctuations could result in lower demand for our
products, as well as currency translation losses;

- changes to and compliance with a variety of foreign laws and regulations
may increase our cost of doing business in these jurisdictions; and

- trade protection measures and import and export licensing requirements
subject us to additional regulation and may prevent us from shipping
products to a particular market and increase our operating costs.

Direct sales we make in countries outside of the United States are
generally priced in local currencies and can be subject to currency exchange
fluctuations. The net impact of currency fluctuations on net revenues and
operating results cannot be precisely measured as our product mix and pricing
change over time in various markets, partially in response to currency
movements. Our results of operations could be harmed by factors such as changes
in foreign currency rates or real economic conditions in the foreign markets in
which we distribute our products. We are primarily exposed to changes in
exchange rates on the Japanese yen, British pound, French franc, and German
deutsche mark. When the U.S. dollar strengthens against these currencies, the
U.S. dollar value of non-U.S. dollar-based sales decreases. When the U.S. dollar
weakens against these currencies, the dollar value of non-U.S. dollar-based
sales increases. Correspondingly, the U.S. dollar value of non-U.S. dollar-based
costs increases when the U.S. dollar weakens and decreases when the U.S. dollar

8
10

strengthens. Overall we are a net receiver of currencies other than the U.S.
dollar and, as such, benefit from a weaker dollar, and are adversely affected by
a stronger dollar relative to major currencies worldwide. Accordingly, changes
in exchange rates, and in particular a strengthening of the U.S. dollar, may
adversely affect our consolidated sales and operating margins as expressed in
U.S. dollars. To minimize currency exposure gains and losses, we may borrow
funds in local currencies, enter into forward exchange contracts, purchase
foreign currency options and promote natural hedges by purchasing components and
incurring expenses in local currencies, whenever feasible.

Our 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 our ability to sell or to manufacture in international
markets. Furthermore, revenues from outside the United States are subject to
inherent risks, including the general economic and political conditions in each
country. 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. We remain cautious with regard to the Japanese market and do not
expect the current Japanese macroeconomic trends to change significantly in the
near term. If the economic trends in Japan significantly worsen in a quarter or
decline over an extended period of time, our results of operations and cash
flows could suffer. Although we have experienced U.S. dollar revenue growth in
the European marketplace on a year over year basis, there can be no assurance
that such trends will continue. In particular, if capital spending declines in
certain countries or industries over an extended period of time our results of
operations and cash flows could suffer.

One of our customers accounted for more than 10% of our revenues in fiscal
1999 and 1998. No individual customer accounted for more than 10% of revenues in
fiscal 1997. Sales to MRA Systems, Inc., an authorized reseller, were
approximately 14% of our fiscal 1999 and 1998 revenues. Our business could
suffer if this customer or another significant customer terminated its business
relationship with us or significantly reduced the amount of business it did with
us. Also see Note 10 of Notes to Consolidated Financial Statements incorporated
by reference herein for additional information concerning sales to foreign
customers and business segments.

Our marketing activities include advertising in computer publications and
the business press, direct mailings to customers and prospects, televised
programs and attendance at trade shows. We maintain a customer resource program,
Sunergy(SM), which includes live interactive satellite broadcasts and provides
electronic access to newsletters and technical information. We also sponsor 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.

Our future operating results will continue to be subject to quarterly
fluctuations based upon a variety of factors. Our operating results usually
fluctuate downward in the first and third quarters of each fiscal year due to
customer buying patterns for hardware and software products and services. Our
operating expenses will continue to increase as we continue to expand our
operations. Our operating results could suffer if our revenues do not increase
at least as fast as our expenses. If, in the future, we acquire technologies,
products or businesses, or we form alliances with companies requiring technology
investments or revenue commitments (such as our recent alliance with AOL), we
will face a number of risks to our business. The risks we may encounter include
those associated with integrating or co-managing operations, personnel, and
technologies acquired or licensed, and the potential for unknown liabilities of
the acquired or combined business. Also, we will include amortization expense of
acquired intangible assets in our financial statements for several years
following these acquisitions. Our business and operating results on a quarterly
basis could be harmed if our acquisition or alliance activities are not
successful.

Our order backlog at June 30, 1999 was approximately $825 million, compared
with approximately $599 million at June 30, 1998. Our 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 our 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

We provide expertise in heterogeneous network computing through a full
range of global services, including support services (systems support for
hardware and software), education 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 1 million systems in more than 170
countries, training more than 75,000 students annually, and providing
consulting, integration and operations assistance to IT organizations worldwide.

In support services, we have increased resources in the field for 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. Our
direct services are complemented by third-party service providers who primarily
deliver hardware support services. Software support continues to be primarily
delivered by our 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 help us expand geographic
coverage without additional fixed cost investment on our part.

We offer a warranty for parts and labor on hardware products, generally for
one year from date of sale and a limited warranty on software, generally for 90
days from date of sale. We service products during the warranty period and
provide contract service after the initial product warranty has expired.
Post-warranty support services are primarily offered through a tiered support
offering called SunSpectrum(SM). 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 36 solution centers worldwide.

Our education services offer 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 education needs of many customers
including managers, operators, developers, system administrators, and end-users.
As an alternative to the classroom, our customers may select technology-based
training options including our web-based learning solution which is available to
those having Internet access, built on the Java platform, and provides modular
courses on Jini technologies. Additionally, we provide interactive training
products on CD-ROM which can be geared for various levels of expertise.

In professional services, we provide the people, processes and technology
to deliver single point-of-contact solutions tailored to meet customer needs.
Our technical and project management experts help customers plan, implement, and
manage heterogeneous computing environments. Our 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, we help with
all phases of creating and implementing Internet solutions. Investments have
been made in competencies in Internet/Java technologies, business applications
and systems and network management.

Certain complex systems we sell require a high level of implementation
support and consequently, a 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 seriously harm our business.

PRODUCT DEVELOPMENT

Our research and product development programs are intended to sustain and
enhance our competitive position by incorporating the latest worldwide advances
in hardware, software, graphics, networking, data communications and storage
technologies. The product development efforts conducted within each of our
businesses are focused on enhancing the performance, reliability, availability,
and serviceability of our hardware and systems software. Additionally, we remain
focused on system software platforms for Internet

10
12

and intranet applications, developing advanced workstation and server
architectures, as well as designing application-specific integrated circuits and
software for networking and distributed computing. Sun's product development
continues to focus on the high-performance implementation of existing standards
and the development of new technology standards.

We conduct research and development worldwide principally in the United
States, France, United Kingdom, Ireland, Japan, and Israel. Research and
development expenses were approximately $1,263 million, $1,014 million and $826
million in fiscal 1999, 1998 and 1997, respectively. In recent years, our
research and development efforts have focused increasingly on the Java
architecture, Solaris software and SPARC microprocessors. We believe that
software development provides and will continue to provide significant
competitive differentiation. Therefore, we devote substantial resources to the
development of workgroup software, networking and data communications, video,
graphics, disk array, object technology and the software development
environment.

The products we make are very complex and if we are unable to rapidly and
successfully develop and introduce new products, we will not be able to satisfy
customer demand. We operate in a highly competitive, quickly changing
environment, and our future success depends on our ability to develop and
introduce new products that our customers choose to buy. If we are unable to
develop new products, our business and operating results would be seriously
harmed. We must quickly develop, introduce and deliver in quantity new, complex
systems, software, and hardware products and components, including our
UltraSPARC(TM) microprocessors, the Solaris operating environment, our
intelligent storage products and other software products, such as those products
under development or to be developed under our recent alliance with AOL. The
development process for these complicated products is very uncertain. It
requires high levels of innovation from both our product designers and our
suppliers of the components used in our products. The development process is
also lengthy and costly. If we fail to accurately anticipate our customers'
needs and technological trends or are otherwise unable to complete the
development of a product on a timely basis, we will be unable to introduce new
products into the market on a timely basis, if at all, and our business and
operating results would be adversely affected. In addition, the successful
development of software products under our alliance with AOL depends on many
factors, including our ability to work effectively within the alliance on
complex product development and any encumbrances that may arise from time to
time that may prevent us from developing, marketing or selling these alliance
software products. If we are unable to successfully develop or market or sell
the alliance software products, or other software products, our business and
operating results could be seriously harmed. Software and hardware products such
as ours may contain known as well as undetected errors and these defects may be
found following introduction and shipment of new products or enhancements to
existing products. Although we attempt to fix errors that we believe would be
considered serious by our customers prior to shipment, we may not be able to
detect or fix all such errors, and this could result in lost revenues and delays
in customer acceptance, and could be detrimental to our business and reputation.

Delays in product development or customer acceptance and implementation of
new products and technologies could seriously harm our business. Delays in the
development and introduction of our products may occur for various reasons. For
example, delays in software development could delay shipments of related new
hardware products. Generally, the computer systems that we sell to customers
incorporate many of our hardware and software products, such as the UltraSPARC
microprocessor, the Solaris operating environment and intelligent storage
products. Any delay in the development of the software and hardware included in
our systems could delay our shipment of these systems.

In addition, if customers decided to delay the adoption and implementation
of new releases of our Solaris operating environment this could also delay
customer acceptance of new hardware products tied to that release. Adopting a
new release of an operating system requires a great deal of time and money for a
customer to convert its systems to the new release. The customer must also work
with software vendors who port their software applications to the new operating
system and make sure these applications will run on the new operating system. As
a result, customers may decide to delay their adoption of a new release of an
operating system because of the cost of a new system and the effort involved to
implement it. Also, customers may wait

11
13

to implement new systems until after January 1, 2000 so that there is less
likelihood of Year 2000 computer problems.

MANUFACTURING AND SUPPLY

Our manufacturing operations consist primarily of final assembly, test and
quality control of systems, materials and components. We manufacture in
California, Oregon, and Scotland, and distribute in California, the Netherlands
and Japan. We have continued efforts to simplify the manufacturing process by
reducing the diversity of system configurations offered, increasing the
standardization of components across product types and establishing local
sources of supply in major geographies.

Our reliance on single source suppliers could delay product shipments and
increase our costs. We depend on many suppliers for the necessary parts and
components to manufacture our products. There are a number of vendors producing
the parts and components that we need. However, there are some components that
can only be purchased from a single vendor due to price, quality or technology
reasons. For example, we depend on Sony for various monitors and on Texas
Instruments for our SPARC microprocessors. If we were unable to purchase the
necessary parts and components from a particular vendor and we had to find a new
supplier for such parts and components, our new and existing product shipments
could be delayed, severely affecting our business and operating results.

Our future operating results depend on our ability to purchase a sufficient
amount of components to meet the demands of our customers. We depend heavily on
our suppliers to timely design, manufacture and deliver the necessary components
for our products. While many of the components we purchase are standard, we do
purchase some components, specifically color monitors and custom memory
integrated circuits such as SRAMS and VRAMS, that require long lead times to
manufacture and deliver. Long lead times make it difficult for us to plan
component inventory levels in order to meet the customer demand for our
products. In addition, in the past, we have experienced shortages in certain of
our components (specifically DRAMS and SRAMS). If a component delivery from a
supplier is delayed, if we experience a shortage in one or more components or if
we are unable to provide for adequate levels of component inventory our new and
existing product shipments could be delayed and our business and operating
results could suffer.

Since we order our components (and in some cases commit to their purchase)
from suppliers in advance of receipt of customer orders for our products that
include these components, we face a substantial inventory risk. As part of our
component inventory planning, we frequently pay certain suppliers well in
advance of receipt of customer orders. For example, we often enter into
noncancelable purchase commitments with vendors early in the manufacturing
process of our microprocessors to make sure we have enough of these components
for our new products to meet customer demand. Because the design and
manufacturing process for these components is very complicated it is possible
that we could experience a design or manufacturing flaw that could delay or even
prevent the production of the components for which we have previously committed
to pay. We also face the risk of ordering too many components, or conversely,
not enough components, since the orders are based on the forecasts of customer
orders rather than actual orders. If we cannot change or be released from the
noncancelable purchase commitments, we could incur significant costs from the
purchase of unusable components, due to a delay in the production of the
components or as a result of inaccurately predicting component orders in advance
of customer orders. Our business and operating results could be seriously harmed
as a result of these increased costs.

The manufacture and introduction of our new hardware and software products
is also a complicated process. Once we have developed a new product we face the
following challenges in the manufacturing process:

- we must be able to manufacture new products in high enough volumes so
that we can have an adequate supply of new products to meet customer
demand;

- we must be able to manufacture the new products at acceptable costs. This
requires us to be able to accurately forecast customer demand so that we
can procure the appropriate components at optimal

12
14

costs. Forecasting demand requires us to predict order volumes, the
correct mixes of our software and hardware products and the correct
configurations of these products;

- we must manage new product introductions so that we can minimize the
impact of customers delaying purchases of existing products in
anticipation of the new product release. We must also try to reduce the
levels of older product and component inventories to minimize inventory
write-offs; and

- we may also decide to adjust prices of our existing products during this
process in order to try to increase customer demand for these products.
If we are introducing new products at the same time or shortly after the
price adjustment, this will complicate our ability to anticipate customer
demand for our new products.

If we were unable to timely develop, manufacture and introduce new products
in sufficient quantity to meet customer demand at acceptable costs or if we were
unable to correctly anticipate customer demand for our new products, our
business and operating results could be significantly harmed.

COMPETITION

If we are unable to compete effectively with existing or new competitors,
our resulting loss of competitive position could result in price reductions,
fewer customer orders, reduced revenues, reduced margins, reduced levels of
profitability and loss of market share. We compete in the hardware and software
products and services markets. These markets are intensely competitive. If we
fail to compete successfully in these markets, the demand for our products would
decrease. Any reduction in demand could lead to a decrease in the prices of our
products, fewer customer orders, reduced revenues, reduced margins, reduced
levels of profitability, and loss of market share. These competitive pressures
could seriously harm our business and operating results.

Our competitors are some of the largest, most successful companies in the
world. They include Hewlett Packard Company (HP), International Business
Machines Corporation (IBM), Compaq Computer Corporation (Compaq) and EMC
Corporation (EMC). Our future competitive performance depends on a number of
factors, including our ability to perform the following:

- continually develop and introduce new products and services with better
prices and performance than offered by our competitors;

- offer a wide range of products and solutions from small single-processor
systems to large complex enterprise-level systems;

- offer solutions to customers that operate effectively within a computing
environment that includes hardware and software from multiple vendors;

- offer products that are reliable and that ensure the security of data and
information;

- create products for which third party software vendors will develop a
wide range of applications; and

- offer high quality products and services.

We also compete with systems manufacturers and resellers of systems based
on microprocessors from Intel Corporation (Intel) and Windows NT operating
system software from Microsoft Corporation (Microsoft). These competitors
include Dell Computer Corporation, HP and Compaq, in addition to Intel and
Microsoft. This competition creates increased pressure, including pricing
pressure, on our workstation and lower-end server product lines. We expect this
competitive pressure to intensify considerably during our fiscal year 2000 with
the anticipated releases of new software products from Microsoft and new
microprocessors from Intel.

The computer systems that we sell are made up of many products and
components, including workstations, servers, storage products, microprocessors,
the Solaris(TM) operating environment and other software products. In addition,
we sell some of these components separately and as add-ons to installed systems.
If we are unable to offer products and services that compete successfully with
the products and services offered by our competitors or that meet the complex
needs of our customers, our business and

13
15

operating results could be seriously harmed. In addition, if in responding to
competitive pressures, we are forced to lower the prices of our products and
services and we are unable to reduce our component costs or improve operating
efficiencies, our business and operating results would be seriously harmed.

Over the last two years, we have invested significantly in our storage
products business with a view to increasing the sales of these products both on
a stand-alone basis to customers using the systems of our competitors and as
part of the systems that we sell. The intelligent storage products business is
intensely competitive. EMC is currently the leader in this market. To the extent
we are unable to penetrate this market and compete effectively, our business and
operating results could be seriously harmed. In addition, we will be making
significant investments over the next few years to develop, market and sell
software products under our recent alliance with AOL and have agreed to
significant minimum revenue commitments. These alliance products are targeted at
the E-commerce market and are strategic to our ability to successfully compete
in this market. If we are unable to successfully compete in this market, our
business and operating results could be seriously harmed.

We have encouraged the use of 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 our products, primarily in the desktop markets. We have also worked to make
our Java technology a programming standard for complex networks. We develop
applications, tools and systems platforms, as well as work with third-parties to
create products and technologies, in order to continue to enhance the Java
platform's capabilities. As part of this effort, we license Java technology
widely to encourage competitors of Sun to also develop products competing with
these applications, tools and platforms.

PATENTS AND LICENSES

We hold a number of U.S. and foreign patents relating to various aspects of
our products and technology. While we believe that patent protection is
important, we also believe that patents are of less competitive significance
than factors such as innovative skills and technological expertise.

We have from time to time been notified that we may be infringing certain
patents or 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. We are evaluating the desirability of entering
into licensing agreements in certain of these cases. Based on industry practice,
we believe that 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 harm our business.

EMPLOYEES

As of June 30, 1999, we had approximately 29,700 employees. We depend on
key employees and face competition in hiring and retaining qualified employees.
Our employees are vital to our success, and our key management, engineering and
other employees are difficult to replace. We expect to continue to increase the
number of our employees to support our growth. We generally do not have
employment contracts with our key employees. Further, we do not maintain key
person life insurance on any of our employees. The expansion of high technology
companies in Silicon Valley and Colorado, as well as many other cities, has
increased demand and competition for qualified personnel. We may not be able to
attract, assimilate or retain additional highly qualified employees in the
future and this could harm our business.

16

ADDITIONAL FACTORS AFFECTING OUR BUSINESS

Our failure or the failure of our business partners and customers to be Year
2000 compliant could harm our business.

Many currently installed computer systems and software products are coded
to accept only two digit entries in the date code field. As the Year 2000
approaches, these code fields will need to be able to distinguish years
beginning with "19" from those beginning with "20." As a result, in less than
six months, computer systems and/or software products used by many companies may
need to be upgraded to comply with such Year 2000 requirements. We are currently
expending resources to review our products and services, as well as our internal
use software in order to identify and modify those products, services and
systems that are not Year 2000 compliant. We believe that the vast majority of
these costs are not incremental to us but represent a reallocation of existing
resources and include regularly scheduled systems upgrades and maintenance. In
addition, we have made custom coding enhancements to our mission critical
internal business systems and we believe that such internal systems are now Year
2000 compliant. We are working to make our remaining internal systems Year 2000
compliant by September 30, 1999.

Although we believe that the costs associated with the aforementioned Year
2000 efforts are not material, we currently estimate that such costs will be
between $40 to $45 million, of which approximately $25 million had been spent
through June 30, 1999. The aforementioned costs are estimates due in large part
to the fact that we do not separately track the internal labor costs associated
with Year 2000 compliance, unless such costs are incurred by individuals devoted
primarily to Year 2000 compliance efforts. These cost estimates do not include
any potential costs related to any customer or other claim. In addition, these
cost estimates are based on the current assessment of the ongoing activities
described above, and are subject to change as we continuously monitor these
activities. We believe any modifications deemed necessary will be made on a
timely basis and we do not believe that the cost of such modifications will
seriously harm our business. We currently expect the aforementioned evaluation
of our products, services and systems and any remediation necessary will be
completed by September 30, 1999. As of June 30, 1999, we had not identified any
items or areas which would require material remediation efforts. Our
expectations as to the extent and timeliness of any modifications required in
order to achieve Year 2000 compliance and the costs related thereto are forward-
looking statements subject to risks and uncertainties. Actual results may vary
materially as a result of a number of factors, including, among others, those
described in this section. We cannot be sure, however, that we will be able to
successfully modify on a timely basis such products, services and systems to
comply with Year 2000 requirements. Our business could suffer if we fail to make
our products, services and systems Year 2000 compliant in time.

We have established a program to assess whether certain of our products are
Year 2000 compliant. Under this program, we are in the process of performing
tests on Sun products listed on our price lists. To monitor this program and to
help customers evaluate their Year 2000 issues we have created a Web site at
http://sun.com/y2000/cpl.html which identifies the following categories:
products that were released Year 2000 compliant; products that require
modifications to be Year 2000 compliant; products under review; products that
are not Year 2000 compliant and need to be replaced with a Year 2000 compliant
product; source code products that could be modified and implemented without our
review; and products that do not process or manipulate date data or have no
date-related technology. We update this list periodically as our analysis of
additional products is completed.

Based on our assessment to date, most of our newly introduced products and
services are Year 2000 compliant, however, we cannot be sure that our current
products do not contain undetected errors or defects associated with Year 2000
functions that may result in material costs to us. In addition, some of our
customers are running products that are not Year 2000 compliant and will require
an upgrade or other remediation to become Year 2000 compliant. We provide
limited warranties as to Year 2000 compliance on certain of our products and
services. Except as specifically provided for in the limited warranties, we do
not believe that we are legally responsible for costs incurred by customers to
achieve Year 2000 compliance. We have been taking steps to identify affected
customers, raise customer awareness related to noncompliance of our older
products and encourage such customers to migrate to current products or product
versions. It is possible that we may

15
17

experience increased expenses if we need to upgrade or perform other remediation
on products that our customers are using that are not Year 2000 compliant. Our
business may also materially suffer if customers become concerned about or are
dissatisfied with our products and services as a result of Year 2000 issues.

We also face risks to the extent that suppliers of products, services and
systems purchased by us or the suppliers of others with whom we transact
business cannot timely provide us with products, components, services or systems
that meet Year 2000 requirements. To the extent that we are not able to test
technology provided by third party hardware or software vendors, we are in the
process of carrying out audits and obtaining Year 2000 compliance certifications
from each of our major vendors that their products and internal systems, as
applicable, are Year 2000 compliant. In the event any such third parties cannot
timely provide us with products, services or systems that meet the Year 2000
requirements, our business could be harmed. Furthermore, a reasonably likely
worst case scenario would be if one of our major vendors experienced a material
disruption in business, which caused us to experience a material disruption in
business. If either our internal systems or the internal systems, products or
services of one or more of our major vendors (including banks, energy suppliers
and transportation providers) fail to achieve Year 2000 compliance, our business
could be seriously harmed. We are currently developing contingency plans to deal
with potential Year 2000 problems related to our internal systems that are
deemed to be high risk and with respect to products and services provided by
outside vendors. We expect these plans to be complete by September 30, 1999. If
these plans are not timely completed or if they are not successful or if new
Year 2000 problems not covered by our contingency plans emerge, our business and
operating results may be seriously harmed.

Although we believe that the cost of Year 2000 modifications for both
internal use software and systems, as well as Sun's products are not material,
we cannot be sure that various factors relating to the Year 2000 compliance
issues will not seriously harm our business or operating results. For example, a
significant amount of litigation may arise out of Year 2000 compliance issues
and we cannot be sure about the extent to which we may be affected by any of
this litigation. Even though we do not believe that we are legally responsible
for our customers' Year 2000 compliance obligations, it is unclear whether
different governments or governmental agencies may decide to allocate liability
relating to Year 2000 compliance to us without regard to specific warranties or
warranty disclaimers. Our business could suffer in any given quarter if any
liability is allocated to us. Furthermore, we do not know how customer spending
patterns may be affected by Year 2000 issues. We believe, however, that
customers will focus on preparing their businesses for the Year 2000 and that
their capital budgets will be spent in large part on remediation efforts,
potentially delaying the purchase and implementation of new systems, thereby
creating less demand for our products and services. Our business could be harmed
if customers delay purchasing our products during the first half of our fiscal
Year 2000 because of Year 2000 concerns, or if our customers are unable to
conduct their business or are prevented from placing orders or paying us because
of their own Year 2000 problems. A significant disruption of our financial
management and control systems or a lengthy interruption in our operations
caused by a Year 2000 related issue could also result in a material adverse
impact on our operating results and financial condition.

OUR ACQUISITION AND ALLIANCE ACTIVITIES COULD DISRUPT OUR ONGOING BUSINESS.

We intend to continue to make investments in companies, products and
technologies, either through acquisitions or investment alliances. For example,
we have purchased several companies in the past and formed alliances, including
our recent alliance with AOL. Acquisitions and alliance activities often involve
risks, including:

- we may experience difficulty in assimilating the acquired operations and
employees;

- we may experience difficulty in managing product co-development
activities with our alliance partners;

- we may be unable to retain the key employees of the acquired operation;

- the acquisition or investment may disrupt our ongoing business;

- we may not be able to incorporate successfully the acquired technology
and operations into our business and maintain uniform standards,
controls, policies and procedures; and

- we may lack the experience to enter into new markets, products or
technologies.

16
18

Some of these factors are beyond our control. Failure to manage these
alliance activities effectively and to integrate acquisitions would affect our
operating results or financial condition.

ITEM 2. PROPERTIES

We conduct our worldwide operations using a combination of leased and owned
facilities. While we believe we have sufficient facilities to conduct business
during fiscal 2000, we will continue to lease and acquire facilities throughout
the world as necessary. Our owned properties consist of an approximately
1,000,000 square foot facility on approximately 57 acres in Menlo Park,
California; an approximately 700,000 square foot facility on approximately 58
acres in Newark, California; an approximately 540,000 square foot facility on
approximately 158 acres in Burlington, Massachusetts; an approximately 530,000
square foot facility on approximately 120 acres in Broomfield, Colorado where an
additional 200,000 square foot facility is under construction; an approximately
260,000 square foot facility on approximately 12 acres in Palo Alto, California;
an approximately 230,000 square foot facility on approximately 24 acres in
Linlithgow, Scotland; an approximately 180,000 square foot facility in
Plantation, Florida; an approximately 140,000 square foot facility in Melbourne,
Florida; an approximately 30,000 square foot facility on approximately 2.5 acres
in Bagshot, England; an 82 acre site in Santa Clara, California where a 630,000
square foot facility is under construction; 40 acres in Farnborough, England
where an approximately 240,000 square foot facility is under construction; and a
parcel of land in Newark, California of approximately 85 acres. We also lease
approximately 7.3 million square feet, including three million square feet is in
the San Francisco Bay Area. The remaining leased space is located in 270 sales
and service offices around the world. A substantial portion of our facilities,
including our corporate headquarters and other critical business operations are
located near major earthquake faults. We are uninsured and do not fund for
earthquake-related losses. In addition, we face risks to the extent that our
suppliers of products, services and systems and others with whom we do business
on a worldwide basis are impacted by an earthquake. As a result, our business,
financial condition or operating results could be materially adversely effected
in the event of a major earthquake.

ITEM 3. LEGAL PROCEEDINGS

On October 7, 1997, we filed suit against Microsoft in the United States
District Court for the Northern District of California alleging breach of
contract, trademark infringement, false advertising, unfair competition,
interference with prospective economic advantage and inducing breach of
contract. We filed an amended complaint on October 14, 1997. Microsoft filed its
answer, affirmative defenses and counterclaims to the amended complaint. The
counterclaims include breach of contract, breach of the covenant of good faith
and fair dealing, violation of the California Business & Professions Code and
declaratory judgment. We believe that the counterclaims are without merit and/or
that we have affirmative defenses and intend vigorously to defend ourselves with
respect thereto. On March 24, 1998 the United States District Court judge ruled
in our favor granting a preliminary injunction directing Microsoft to cease
using our Java Compatible Logo(TM) on Microsoft products that failed to pass the
applicable test suites from Sun. In addition, on May 12, 1998, we filed a second
amended complaint alleging copyright infringement by Microsoft and motions
requesting further preliminary injunctive relief directed against the planned
release by Microsoft of additional products that failed to pass our applicable
test suites. The Court held hearings and arguments on such motions on September
8, 9, and 10, 1998. On November 17, 1998, the District Court issued an Order
granting, in substantial part, our request for preliminary injunctions. On
December 15, 1998 Microsoft filed notice of its intent to appeal the District
Court's Order and on December 18, 1998 Microsoft filed motions with the District
Court to extend the time for compliance with the Order and to clarify or modify
the Order. On January 13, 1999, Microsoft filed an appeal to the District
Court's Order issued on November 17, 1998. On January 22, 1999, Sun and
Microsoft filed numerous motions for summary judgment with the District Court.
On May 24, 1999, the District Court issued tentative rulings on three pending
motions for summary judgment which were argued on June 24, 1999.

An appellate argument before the Ninth Circuit Court of Appeals relating to
the November 1998 preliminary injunction granted in our favor occurred on June
16, 1999. On August 23, 1999, a three-judge panel of the Ninth Circuit Court of
Appeals issued an opinion and ruling on Microsoft's appeal to that Court

17
19

of the November 1998 preliminary injunction issued by the District Court. The
Ninth Circuit panel, in its ruling, found sufficient evidence in the record that
Sun is likely to prevail on the merits of its breach of contract claims against
Microsoft. However, the panel vacated the copyright infringement-based
injunction that the District Court had entered and remanded the case back to the
District Court for further consideration. The Remand Order and the lifting of
the injunction took effect on September 13, 1999. The District Court has
scheduled a hearing regarding the Remand Order for October 15, 1999. If the
injunction is not reinstated, Microsoft may, during the pendency of the case,
elect to offer products that fail to pass the applicable test suites from Sun.
We believe that the outcome of this matter will not have a material adverse
impact on our financial condition, results of operations or cash flows in any
given fiscal year.
