<PAGE>
    COSMO SOFTWARE  The Company's Cosmo Software business offers a family of
content creation, browsing and management tools for the World Wide Web and
intranet markets. The Cosmo-TM- products are intended to facilitate the creation
of media-rich 3D environments and especially to take advantage of the power of
the industry standard Virtual Reality Modeling Language (VRML) developed by
Silicon Graphics. Cosmo Software also develops innovative 3D Web environments
under contract for online service customers like Disney Online and Microsoft's
MSN.
 
SERVERS
 
    ORIGIN200  The Origin200-TM- is a deskside server employing from one to four
processors. The Origin200 server is designed for departmental and other
workgroup serving applications as well as Web serving.
 
    ORIGIN2000  The Origin2000-TM- family of high-performance servers is based
on the Company's innovative non-uniform memory access (NUMA) architecture, which
offers the ability to scale from as few as four to as many as hundreds of
processors in the Cray Origin2000 line while maintaining almost linear
performance per processor. This "pay as you go" flexibility is highly attractive
to customers because it allows them to buy what they need today, add as needed
while protecting their investment, and redeploy when conditions change. Key
applications in the technical and scientific markets include finite element
analysis (to determine the impact of elements like stress and temperature),
quantum chemistry calculation, seismic analysis and computational fluid
dynamics. Key uses in the enterprise market include data mining (to analyze and
organize database information), product data management for manufacturing, and
commercial transaction processing. Origin servers also are used as media
servers, World Wide Web site servers and file servers.
 
    The CRAY T3E-TM- highly scalable supercomputing systems employ a highly
parallel architecture ranging from 16 to as many as 2,048 processors for a broad
range of scientific and industrial applications as diverse as petroleum
exploration, aerospace engineering and defense applications.
 
    VECTOR SYSTEMS  The Cray T90-TM- family of supercomputers delivers maximum
performance for vectorized supercomputing applications. The large memory
bandwidth of T90 systems make them ideal for problems involving huge amounts of
data, such as weather and climate modeling and large-scale auto engineering. The
Cray J90-TM- family uses low-cost CMOS technology to deliver affordable
supercomputing for vectorized applications like molecular modeling, ecosystem
simulation, medical imaging and vehicle dynamics simulation.
 
MIPS RISC MICROPROCESSORS
 
    The Company's system products, except the Cray T3E and vector families, are
based on the MIPS RISC microprocessor architecture. The Company's MIPS RISC
microprocessor designs incorporate a general purpose architecture and
instruction set designed for high performance over a wide range of applications.
The MIPS RISC microprocessor designs make efficient use of instruction
"pipelining" techniques and proprietary compilers, allowing significant
performance gains to be realized by optimizing the tradeoff between compiler and
microprocessor functions. The versatility of the MIPS RISC architecture makes it
suitable for computer applications from entry-level desktop systems up to
supercomputers.
 
    MIPS RISC microprocessors are also used in a wide variety of noncomputer
applications, including disk drives, printers and copiers and, increasingly,
consumer electronics products. Silicon Graphics computers represent only a small
percentage of the worldwide consumption of MIPS RISC microprocessors.
 
    The Company does not manufacture or sell MIPS RISC microprocessors and
related devices. It licenses its designs to "semiconductor partners" who
manufacture and sell the parts. The Company's current licensees are: Integrated
Device Technology, Inc.; LSI Logic Corporation; NEC Corporation; NKK
 
                                       2
<PAGE>
Corporation; Philips Semiconductor; Quantum Effect Design, Inc. and Toshiba
Corporation. The semiconductor partners pay the Company unit royalties based
upon sales.
 
APPLICATIONS SOFTWARE
 
    Because the Company has historically developed only a very limited set of
applications software, its customers must either develop or license from a third
party the software necessary to address their needs. The Company maintains
active programs to encourage independent software development for its systems,
including training, technology support and cooperative marketing. The Company
believes that there are currently over 2,500 registered application software
programs offered for use on its systems.
 
MARKETING, SALES AND DISTRIBUTION
 
    The Company sells its system products through its own direct sales force and
through several indirect channels. In fiscal 1997 direct sales accounted for
approximately half of the Company's product revenues. The direct sales and
support organization operates throughout the United States and in all
significant international markets. The Company serves smaller international
markets through distributors.
 
    The principal indirect channels through which the Company operates are the
following:
 
    - VARS, or value added resellers, are software companies that develop or
      customize their proprietary software specifically for use with the special
      graphics hardware of the Company's workstations. VARs purchase
      workstations from the Company or its North American distributor,
      incorporate their applications software and resell the systems to
      end-users.
 
    - VADS, or value added dealers, are typically direct sales organizations
      that sell primarily into a single vertical market and incorporate
      appropriate specialized third-party software with the Company's hardware
      for sale to their customers.
 
    - SYSTEMS INTEGRATORS include Silicon Graphics systems in much larger
      systems customized for use by the federal government and large commercial
      clients.
 
Many of the Company's resellers are served through Access Graphics, an
independent company that functions as a master reseller of the Company's system
products.
 
    Information with respect to international operations and export sales may be
found in Note 14 to the Consolidated Financial Statements included in Part II
below. See also "Risks That Affect Our Business" below. Although no customer
accounted for 10% or more of the Company's total revenues for fiscal 1997, 1996
or 1995, a significant reduction or delay in sales to major customers could
adversely affect the Company's operating results.
 
CUSTOMER SERVICE AND SUPPORT
 
    The Company believes that the quality and reliability of its system products
and the ongoing support of such products are important elements of its
competitive strategy. The Company's customer service organization includes field
service engineers, field product and applications specialists, product support
engineers, training specialists and administrative support personnel. In
addition, the Company provides customer education through regularly scheduled
courses in system software administration, applications programming and hardware
maintenance. The Company provides local customer support from its regional sales
and service offices located in North America, Western Europe and the Pacific
Rim, with spare parts inventory stored at each location. International
distributors provide training and support for products sold by them.
 
                                       3
<PAGE>
    The Company typically provides a standard "return to factory" hardware
warranty against defects in materials and workmanship for periods of up to one
year.
 
RESEARCH AND DEVELOPMENT
 
    The Company's research and development program is directed principally
toward maintaining and enhancing the Company's competitive position through
incorporating the latest advances in microprocessor, hardware, software and
networking technologies. This effort is focused specifically on developing and
enhancing its computing architectures, MIPS RISC microprocessors, graphics
subsystems, VLSI technology, compiler software, operating system, applications
software and development tools. Simultaneously, the Company seeks to develop new
ways in which to increase product reliability, reduce manufacturing costs and
improve product development lead times.
 
    The Company is currently devoting significant research and development
resources to potential systems based on the Windows NT operating system and
Intel microprocessors. There are no assurances, however, that such systems will
be brought to market, and in any event, the Company does not expect that such
systems would account for any material revenue in fiscal 1998.
 
    During fiscal 1997, 1996 and 1995, the Company spent approximately $479
million, $353 million, and $248 million, respectively, on research and
development. Those amounts represented 13.1%, 12.1% and 11.1%, respectively, of
revenues.
 
MANUFACTURING
 
    The Company's manufacturing operations primarily involve assembling high
level subassemblies and systems and testing major purchased subassemblies. All
products are subjected to substantial environmental stress and electronic
testing prior to shipment to customers. The Company primarily manufactures and
ships its products from its facilities in Mountain View, California, Chippewa
Falls, Wisconsin and near Neuchatel, Switzerland.
 
    The Company continually evaluates the allocation of manufacturing activities
among the Company's own operations and those of suppliers and subcontractors.
This allocation may be affected by fluctuations in the volume of business,
geopolitical, economic and technological developments and other factors.
 
    Most of the Company's products incorporate components that are available
from only one or limited sources. Key components include application specific
integrated circuits ("ASICs"), storage products, especially RAID-based products,
and certain memory products.
 
    Reliance on single or limited source vendors involves several risks,
including the possibility of a shortage of certain key components that meet the
Company's product specifications. Risks also include long lead times, reduced
control over delivery schedules, and the possibility of charges for excess and
obsolete inventory.
 
    The Company also has single sources for certain peripherals, communications
controllers and power supplies, and the monitors and plastic cabinets used
across the Company's system products. The Company believes that, in most of
these cases, alternative sources of supply could be developed over a period of
time. However, a reduction or interruption in supply or a significant increase
in the price of one or more single or limited source components would, at least
in the short term, adversely affect the Company's operating results.
 
    Many of the Company's suppliers are located outside the United States,
especially in Japan. The prices of parts from these suppliers have been and may
be affected significantly by such factors as protectionist measures and changes
in currency exchange rates between the United States and other countries. In
addition, changes in the availability of certain memory chips (DRAMs, SRAMs and
VRAMs) have caused, and in the future may cause, significant changes in their
prices.
 
                                       4
<PAGE>
COMPETITION
 
    The computer industry is highly competitive and is characterized by rapid
technological advances in both hardware and software development. These advances
result in frequent new product introductions, short product life cycles and
increased new product capabilities, typically representing significant price/
performance improvements. The principal competitive factors in the Company's
market are product features, price/performance, networking capabilities, product
quality and reliability, ease of use, capabilities of the system software,
availability of applications software, customer support, product availability,
corporate reputation and price. The strong competition faced throughout the
Company's product line can result in significant discounting from list price.
 
    The Company's principal competition has historically come from other
workstation and computer system manufacturers and, to a lesser extent, from
graphics subsystem and terminal vendors and graphics integrated circuit
manufacturers. The principal workstation and computer manufacturers that compete
in the Company's markets are Compaq Computers, Digital Equipment, Hewlett
Packard, IBM and Sun Microsystems. The Company is facing increasing competition
at the lowest end of the workstation market from systems based on personal
computer technologies such as the Windows NT operating system, Intel
microprocessors and graphics acceleration cards. The Company has under
development a desktop system that will be based on Intel microprocessors and the
Windows NT operating system. There can be no assurance that this system will be
introduced or gain commercial acceptance.
 
    In the high end of the supercomputer market, the Company faces competition
from IBM as well as from NEC, Hitachi and Fujitsu. In the applications software
market and certain other emerging markets the Company's principal competitor is
Microsoft.
 
    The Company's MIPS RISC microprocessor architecture and technology compete
directly with microprocessor products offered by manufacturers of other
microprocessor designs, in particular those offered by Intel, IBM, Digital, HP,
Motorola and Sun.
 
PROPRIETARY RIGHTS AND LICENSES
 
    The Company has been granted or has applications pending for a significant
number of U.S. patents, and will continue to seek patent coverage for its
inventions in both the United States and foreign countries. The Company also has
applied for and holds various trademark registrations in the United States and
in selected foreign countries. The Company will continue to seek protection for
its inventions, trademarks, maskworks and copyrights where appropriate.
 
    As is customary in its industry, the Company licenses from third parties a
wide range of software for its internal use and for the use of its customers.
The Company licenses the UNIX operating system on a non-exclusive basis from
Novell, Inc., and sublicenses it to its customers.
 
    The Company's ability to compete may be affected by its ability to protect
proprietary information and to obtain necessary licenses on commercially
reasonable terms. The extent to which U.S. and international intellectual
property laws protect the Company's products, and the enforceability of end-user
license agreements, have not been fully determined, and the computer industry
has seen a substantial increase in litigation with respect to intellectual
property matters. Such litigation or changes in the interpretation of
intellectual property laws could expand or reduce the extent to which the
Company or its competitors are able to protect their intellectual property or
require changes in the design of products which could have an adverse impact on
the Company. The Company has several intellectual property lawsuits pending
against it today. There can be no assurance that the Company will not be made a
party to significant litigation regarding intellectual property matters in the
future. See "Legal Proceedings."
 
                                       5
<PAGE>
EMPLOYEES
 
    As of June 30, 1997, the Company had approximately 10,930 full-time
employees. The Company's future success will depend, in part, on its ability to
continue to attract, retain and motivate highly qualified technical, marketing
and management personnel, who are in great demand. The Company has never had a
work stoppage, and no employees are represented by a labor union. The Company
has workers' councils where required by European Union or other applicable laws.
The Company believes that its employee relations are good.
 
CORPORATE DATA
 
    The Company was originally incorporated as a California corporation in
November 1981, and reincorporated as a Delaware corporation in January 1990.
 
ITEM 2. PROPERTIES
 
    The Company believes that, while it currently has or is developing
sufficient facilities to conduct its operations during fiscal 1998, it will
continue to acquire both leased and owned facilities throughout the world as its
business requires. The Company leases sales, service and administrative offices
worldwide and has its principal corporate and manufacturing facilities in the
following locations:
 
    CALIFORNIA The Company's corporate offices and its primary research and
development and manufacturing operations are located in Mountain View,
California, where the Company occupies a total of about 1,832,500 square feet.
These facilities include a ten-building campus facility comprising approximately
726,500 square feet, leased by the Company through the years 2000 to 2005; a
four-building, 500,000 square foot campus facility completed in fiscal 1997 on
22 acres of leased land in the same area; and a sales headquarters building
comprising approximately 112,000 square feet and located on 7.5 acres owned by
the Company near its Mountain View headquarters. The Company also leases ten
other buildings near its Mountain View headquarters, comprising approximately
490,000 square feet.
 
    MINNESOTA AND WISCONSIN The Company also owns manufacturing, research and
development and service facilities comprising approximately 749,000 square feet
in Chippewa Falls, Wisconsin and research and development, sales and
administrative facilities comprising 495,000 square feet in Eagan, Minnesota.
 
    SWITZERLAND The Company's European manufacturing and support center near
Neuchatel, Switzerland is located in a facility owned by the Company, consisting
of approximately 170,000 square feet.
 
ITEM 3. LEGAL PROCEEDINGS
 
    The Company is defending the lawsuits described below. The Company believes
that it has good defenses to the claims in each of these lawsuits and is
defending each of them vigorously.
 
    The Company is defending a securities class action lawsuit filed in U.S.
District Court for the Northern District of California in January 1996. The suit
alleges that the Company and certain of its officers and directors made material
misrepresentations and omissions during the period from September to December
1995. In May 1996, the District Court dismissed the securities class action with
prejudice. The plaintiffs' appeal to the U.S. Court of Appeals for the Ninth
Circuit is pending.
 
    The Company also is defending securities class action lawsuits involving
MIPS Computer Systems, Inc., which the Company acquired in June 1992, and Alias
Research Inc., which the Company acquired in June 1995. The MIPS case, which was
filed in the U.S. District Court for the Northern District of California in
1992, alleges that MIPS and certain of its officers and directors made material
misrepresentations and omissions during the period from January to October of
1991. In September 1996, the U.S. Court of Appeals for the Ninth Circuit
reversed the summary judgment granted in defendants' favor in
 
                                       6
<PAGE>
June 1994. The Company's petition for review by the U.S. Supreme Court is
pending. The Alias case, which was filed in the U.S. District Court for the
District of Connecticut in 1991, alleges that Alias and certain of its officers
and directors made material misrepresentations and omissions during the period
from May 1991 to April 1992. Alias' motion to dismiss the amended complaint is
pending.
 
    The Company also is defending a patent infringement lawsuit filed by Martin
Marietta Corp. in the U.S. District Court for the Middle District of Florida in
September 1995. The Company has filed a counterclaim seeking to invalidate the
principal patent at issue in the lawsuit, and Martin Marietta has requested the
U.S. Patent and Trademark Office to re-examine the patent. The District Court
has set a trial date for the lawsuit in February 1998.
 
    In July 1996, the Company's Cray Research subsidiary filed a petition with
the U.S. Department of Commerce and the International Trade Commission alleging
that sales of vector supercomputers by Japanese companies violated U.S.
anti-dumping laws. In October 1996, NEC filed a lawsuit in the Court of
International Trade to prevent the Commerce Department from investigating these
anti-dumping claims on the grounds that it was tainted by prejudgment. Cray
Research joined this lawsuit as an interested party. In August 1997, the Court
of International Trade ruled that the Commerce Department investigation was fair
and conducted in compliance with the requirements of the U.S. anti-dumping laws.
The Commerce Department has determined that NEC and Fujitsu are illegally
dumping vector supercomputers in the U.S. market. In September, 1997, the
International Trade Commission ruled that this activity has injured and could
cause further injury to the domestic market. As a result of these findings,
antidumping duties will be imposed on vector supercomputers imported into the
U.S. market by Japanese vendors.
 
    The U.S. Departments of Commerce and Justice are investigating the Company's
compliance with export control laws in connection with sales of its computer
systems, including the sale of certain computer systems to a customer in Russia
in fiscal 1997.
 
    The Company routinely receives communications from third parties asserting
patent or other rights covering the Company's products and technologies. Based
upon the Company's evaluation, it may take no actions or it may seek to obtain a
license. There can be no assurance in any give case that a license will be
available on terms the Company considers reasonable, or that litigation will not
ensue.
 
    Management is not aware of any pending disputes, including those described
above, that would be likely to have a material adverse effect on the Company's
financial condition, results of operations or liquidity. However, management's
evaluation of the likely impact of these pending disputes could change in the
future.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
    The matters addressed in this discussion, with the exception of the
historical information presented, are forward looking statements involving risks
and uncertainties, including the risks discussed under the heading "Risks That
Affect Our Business" and elsewhere in this report.
 
INTRODUCTION
 
    The following tables and discussion present certain financial information on
a comparative basis. The Company's fiscal 1996 results reflect the fourth
quarter acquisition of Cray Research in a business combination accounted for
under the purchase method. To provide a meaningful comparison of fiscal 1997 and
fiscal 1996 results, certain items (revenue, gross margin and operating expenses
other than merger-related expense) are presented on a pro forma combined basis
(as if the acquisition had occurred at the beginning of fiscal 1996 and
excluding the results of the Cray Business Systems Division which was disposed
in the first quarter of fiscal 1997) in addition to the actual fiscal 1996
results. Certain fiscal 1996 Cray Research amounts have also been reclassified
to conform to the current year presentation.

REVENUE
 
    Revenue growth in fiscal 1997 compared with pro forma fiscal 1996 reflected
increased shipments of servers as well as increased service revenue supporting a
larger installed base, offsetting a decline in graphics systems shipments. The
revenue growth rate declined substantially from 31% in fiscal 1996 to 7% in
fiscal 1997. However, the 1996 revenue growth rate of 31% includes incremental
Cray Research revenue for the fourth quarter of fiscal 1996. Excluding the
effect of Cray Research revenue for the fourth quarter of fiscal 1996, the
fiscal 1996 growth rate would have been 24%. Factors contributing to the fiscal
1997 decline in the revenue growth rate included the significant product
transitions which were not completed until the fourth quarter, as well as
softness in international business, particularly in Europe.
 
    As illustrated by the Company's fiscal 1997 results, the process of
completing new products and rapidly bringing them into volume production entails
substantial risks. See "Risks That Affect Our Business--Product Development and
Introduction."
 
    The mix of revenue between servers and graphics systems changed
significantly in fiscal 1997, an expected result of the Cray Research
acquisition. While the Company experienced revenue growth in fiscal 1997 across
its server product line, particularly in the high performance segments, graphics
systems revenue was down. Server and graphics systems unit volumes increased in
each of the years presented. Server product revenue per unit increased and
graphics systems revenue per unit decreased in fiscal 1997 compared with pro
forma fiscal 1996, while overall product revenue per unit has remained
substantially unchanged.
 
    Service revenue, which is comprised of hardware and software support and
maintenance, remained fairly constant as a percentage of total revenue in fiscal
1997 compared with pro forma fiscal 1996. The percentage of service revenue to
total revenue in these two periods is higher than that for 1995 due principally
to the additional Cray Research installed base.
 
                                       12
<PAGE>
    While the Company's geographic revenue mix had in recent years been shifting
towards its international operations, in fiscal 1997 that trend was reversed,
principally due to weakness in European business as compared to prior periods.
Revenue from Rest of World, principally Japan, represented approximately 22% of
total revenue in fiscal 1997, 24% in pro forma fiscal 1996 and 22% in fiscal
1995. Revenue growth in Japan slowed in fiscal 1997 compared with prior periods
partially as a result of a strengthened U.S. dollar. European revenue was also
somewhat adversely affected by currency changes.
 
    The Company's consolidated backlog at June 30, 1997 was $537 million,
compared with backlog of $572 million at June 30, 1996.
 
GROSS MARGIN
 
    Cost of product and other revenue includes costs related to product
shipments, including materials, labor, overhead and other direct or allocated
costs involved in their manufacture or delivery. Costs associated with
non-recurring engineering revenue are recognized in research and development
expense. Cost of service revenue includes all costs incurred in the support and
maintenance of the Company's products.
 
    Silicon Graphics' overall gross margin decreased from 47.1% in pro forma
fiscal 1996 to 44.8% in fiscal 1997. The decline was due principally to product
transition costs and relatively higher revenue in the U.S. where margins
typically are lower as compared with international margins.
 
    In fiscal 1996, the overall gross margin decreased to 49.3% from 53.7% in
fiscal 1995. The decrease was due principally to discounting on product sales
resulting from increased competition, as well as the effect of amortization in
the fourth quarter of fiscal 1996 of purchase accounting adjustments made to the
carrying value of acquired inventory and service contracts.
 
    The Company's gross margins are affected by a number of factors, including
geographic and product mix, and will fluctuate from period to period. The
Company expects its gross margins to be higher in fiscal 1998 than in fiscal
1997, following completion of the major product transition in late fiscal 1997.
Furthermore, the Cray Research purchase accounting adjustments to inventory and
service contracts are now fully amortized and thus will have no further
financial statement impact. Gross margins will nonetheless continue to be
affected by competitive pricing programs. See "Risks That Affect Our Business."
 
OPERATING EXPENSE
 
    Research and development spending in fiscal 1997 increased 14% in absolute
dollars compared with pro forma fiscal 1996, as the Company continued its new
product development programs. Research and development spending also grew as a
percentage of total revenue to 13.1% from 12.3%, largely because the Company
failed to achieve its planned revenue. Research and development spending
increased 43% in absolute dollars (to $353 million from $248 million) and as a
percentage of total revenue (to 12.1% from 11.1%) in fiscal 1996 compared with
fiscal 1995. The increase in the amount of expense resulted in part from the
inclusion of $30 million of Cray Research expenses in the fourth quarter, as
well as spending on projects related to new products introduced in fiscal 1997.
Because of the Company's belief that success in its marketplace requires a
continuous flow of new products, it expects to continue to increase the dollar
amount of research and development spending in fiscal 1998.
 
    Selling, general and administrative expenses increased 13% in absolute
dollars (to $1,038 million from $916 million) and as a percentage of total
revenue (to 28.3% from 26.8%) in fiscal 1997 compared with pro forma fiscal
1996. The increase in the amount of expense resulted from costs of new product
introductions as well as from direct costs related to the increase in sales
personnel during fiscal 1997. Selling, general and administrative expenses
increased 30% in absolute dollars (to $808 million from $619 million) and was
unchanged as a percentage of total revenue in fiscal 1996 compared with fiscal
1995. The increase in the amount of expense resulted in part from the inclusion
of $38 million of Cray Research expenses in the fourth quarter, as well as
continued investments in the Company's sales organization. The Company
 
                                       13
<PAGE>
expects selling, general and administrative expenses as a percentage of
anticipated revenue in fiscal 1998 to be roughly comparable to the fiscal 1997
level.
 
IMPACT OF CURRENCY
 
    The net effect of currency changes was not significant in any of the past
three fiscal years, although currency fluctuations have had and can have
material impacts on particular quarters.
 
OTHER OPERATING RESULTS
 
    ACQUIRED IN-PROCESS TECHNOLOGY  The Company recognized a one-time, non-tax
deductible charge of $98.2 million in the fourth quarter of fiscal 1996 for
in-process technology acquired in the Cray Research merger that had not yet
reached technological feasibility and that had no alternative future use.
 
    MERGER-RELATED EXPENSES  Merger-related expenses in fiscal 1997 relate
primarily to the Cray Research acquisition and consist principally of costs
associated with the integration of Silicon Graphics and Cray Research
information systems, accounting processes and marketing and human resource
activities. The Company expects to incur an additional $3 million of similar
merger-related expenses during fiscal 1998.
 
    INTEREST EXPENSE  Consolidated interest expense increased in fiscal 1997 and
in fiscal 1996 principally as a result of borrowings associated with the Cray
Research acquisition. The Company does not expect a significant change in the
level of interest expense in fiscal 1998.
 
    INTEREST INCOME AND OTHER, NET  Consolidated interest income and other, net
for fiscal 1997 decreased 66% compared with fiscal 1996, reflecting lower
interest income due to significantly lower average invested cash balances, costs
associated with the expansion of the Company's economic hedging program and the
write-off of an investment in a software company. Consolidated interest income
and other, net for fiscal 1996 increased by 19% over the prior year. This was
primarily the result of higher invested cash balances prior to the closing of
the Cray Research tender offer on April 2, 1996, offset by the Company's $10
million share of losses in a joint venture. The Company expects interest income
and other for fiscal 1998 to increase due to improved cash flows as programs
designed to improve asset management are implemented.
 
    PROVISION FOR INCOME TAXES  The consolidated effective tax rate for fiscal
1997 was approximately 20% compared with 39% in fiscal 1996 and 29% in fiscal
1995. The effective tax rate for fiscal 1997 differs from the Federal statutory
rate and is lower than in prior periods primarily as a result of the reinstated
U.S. federal research tax credit, proportionately higher earnings in low tax
jurisdictions, and proportionately higher foreign sales corporation benefits,
offset partially by foreign losses for which no benefit has been recorded. The
1996 rate also reflected the impact of the write-off of acquired in-process
technology for which there was no tax benefit.
 
    The Company does not provide for US federal income taxes on undistributed
earnings of foreign subsidiaries which it intends to permanently reinvest in
those operations. The effective tax rate for fiscal 1998 is expected to increase
over the fiscal 1997 rate primarily due to proportionately lower anticipated
earnings in low tax jurisdictions.
 
                                       14
<PAGE>
FINANCIAL CONDITION
 
    The Company's cash position remained substantially unchanged in fiscal 1997.
At June 30, 1997, cash, cash equivalents and short- and long-term investments
net of short-term borrowings, totaled $330 million, up slightly from $320
million at June 30, 1996.
 
    Operating activities generated $170 million in fiscal 1997, compared with
$212 million in fiscal 1996 and $234 million in fiscal 1995. Fiscal 1997 and
1996 net income was affected by a number of charges that did not use cash: $42
million of reduced gross margin associated with the write-up of acquired Cray
Research inventories and service contracts and a $4 million charge for the
write-off of an investment in a software company in fiscal 1997 and the $98
million write-off of acquired in-process technology and $18 million of reduced
gross margin associated with the write-up of acquired Cray Research inventories
in fiscal 1996. The impact of the fiscal 1997 and 1996 charges was somewhat
offset by increased deferred tax benefit provisions, as well as, in fiscal 1996,
the minority interest in Cray Research loss, which did not provide cash. The
growth in fiscal 1997 receivables reflects higher sales levels and longer
collection cycles. Inventory grew significantly in fiscal 1997 in support of the
product transition as well as to support higher revenue levels. The Company
believes its receivables and inventory levels are higher than its operations
require and it has commenced programs designed to improve its asset management
processes and reduce receivables and inventory levels.
 
    Investing activities, other than changes in the Company's marketable
investments, consumed $301 million in cash during fiscal 1997, compared with
$659 million during fiscal 1996 and $127 million during fiscal 1995. Cash
outlays for capital expenditures were slightly lower as a percentage of total
revenue than in fiscal 1996. Cash outlays for other assets in fiscal 1997 were
higher than in prior years and relate principally to spare parts built to
support the Company's new products introduced during the year. The fiscal 1996
tender offer for Cray Research used approximately $408 million of cash, net of
cash acquired.
 
    In December 1996, the Company's subsidiary in Japan entered into long-term
borrowing arrangements under which it borrowed 6 billion yen ($53 million at the
fiscal year-end exchange rate) for a period of five years. In September 1997,
the Company exchanged $231 million principal amount of new 5 1/4% Senior
Convertible Notes due 2004 (the "Senior Notes") for approximately 98% of its
outstanding Zero Coupon Convertible Debentures due 2013 (the "Zero Coupon
Debentures"). There was no change in the carrying value of the Company's debt.
In each of the past three years the Company's employee stock plans have been an
additional source of cash. In October 1995 the Company announced a program to
repurchase seven million shares of common stock to manage the dilution created
by employee stock plans. Under this program, 2,452,600 shares of common stock
were repurchased for $76 million. The Company has not repurchased any shares
since it entered into its merger agreement with Cray Research in February 1996.
 
    At June 30, 1997, the Company's principal sources of liquidity included
cash, cash equivalents and marketable investments of $374 million ($330 million,
net of short-term borrowings) and up to $250 million available under its
three-year revolving credit facility. At this time the Company expects fiscal
1998 capital expenditures to be comparable as a percentage of total revenue to
fiscal 1997. In connection with the acquisition of Cray Research the Company
also has recorded an accrual of approximately $39 million for exit costs related
to exiting facilities and streamlining duplicate administrative activities.
During fiscal 1997 cash outlays for these activities were approximately $20
million. Future cash outlays related to exit activities are estimated to be
approximately $6 million, most of which are expected to be incurred over the
next two years.
 
    The Company's cash and marketable investments, along with the credit
facility, cash generated from operations and other resources available to the
Company, should be adequate to fund the Company's projected cash flow needs. The
Company believes that the level of financial resources is an important
competitive factor in the computer industry and, accordingly, may elect to raise
additional capital through debt or equity financing in anticipation of future
needs.

RISKS THAT AFFECT OUR BUSINESS
 
    Silicon Graphics operates in a rapidly changing environment that involves a
number of risks, some of which are beyond the Company's control. The following
discussion highlights some of these risks.
 
    PERIOD TO PERIOD FLUCTUATIONS  The Company's operating results may fluctuate
for a number of reasons. Delivery cycles are typically short, other than for
certain large-scale server products. Well over half of each quarter's revenue
results from orders booked and shipped during the third month, and
disproportionately in the latter half of that month. These factors make the
forecasting of revenue inherently uncertain. Because the Company plans its
operating expenses, many of which are relatively fixed in the short term, on
expected revenue, even a relatively small revenue shortfall may cause a period's
results to be substantially below expectations. Such a revenue shortfall could
arise from any number of factors, including lower than expected demand, supply
constraints, delays in the availability of new products, transit interruptions,
overall economic conditions or natural disasters. The timing of customer
acceptance of certain large-scale server products may also have a significant
effect on periodic operating results. Margins are heavily influenced by mix
considerations, including geographical mix, the mix of service and non-recurring
engineering revenue, the mix of high-end and desktop products and application
software, as well as the mix of configurations within these product categories.
 
    The Company's results have followed a seasonal pattern, with stronger
sequential growth in the second and fourth fiscal quarters, reflecting the
buying patterns of the Company's customers.
 
    The Company's stock price, like that of other technology companies, is
subject to significant volatility. If revenue or earnings in any quarter fail to
meet the investment community's expectations, there could be an immediate impact
on the Company's stock price. The stock price may also be affected by broader
market trends unrelated to the Company's performance.
 
    PRODUCT DEVELOPMENT AND INTRODUCTION  The Company's continued success
depends on its ability to develop and rapidly bring to volume production highly
differentiated, technologically complex and innovative products. Product
transitions are a recurring part of the Company's business. During fiscal 1997,
for example, the Company replaced most of its product line, including both
graphics and server systems. A number of risks are inherent in this process.
 
    The development of new technology and products is increasingly complex and
uncertain, which increases the risk of delays. The introduction of a new
computer system requires close collaboration and continued technological
advancement involving multiple hardware and software design and manufacturing
teams within the Company as well as teams at outside suppliers of key components
such as semiconductor and storage products. The failure of any one of these
elements could cause the Company's new products to fail to meet specifications
or to miss the aggressive timetables that the Company establishes. As the
variety and complexity of the Company's product families increase, the process
of planning production and inventory levels also becomes more difficult. In
addition, the extent to which a new product gains rapid acceptance is strongly
affected by the availability of key software applications optimized for the new
systems. There is no assurance that acceptance of the Company's new systems will
not be affected by delays in this process.
 
    Short product life cycles place a premium on the Company's ability to manage
the transition from current products to new products. The Company often
announces new products in the early part of a quarter, while the product is in
the final stages of development, and seeks to manufacture and ship the product
in volume in the same quarter. The Company's results could be adversely affected
by such factors as development delays, the release of products to manufacturing
late in any quarter, quality or yield problems experienced by suppliers,
variations in product costs, delays in customer purchases of existing products
in anticipation of the introduction of new products, and excess inventories of
older products and components.
 
                                       16
<PAGE>
    PROCESS RE-ENGINEERING  The Company is undertaking a series of programs
aimed at redesigning some of its core business processes, including forecasting,
supply chain management, order fulfillment and collection of accounts
receivable. The goals of these programs include more predictable results of
operations, greater quality and customer satisfaction, and improved asset
management. The Company believes that the success of these programs is critical
to its long-term competitive position. Implementing these changes will require,
among other things, enhanced information systems, substantial training and
disciplined execution. There can be no assurance that these programs will be
implemented successfully, or that disruptions of the Company's operations will
not occur in the process.
 
    COMPETITION  The computer industry is highly competitive, with rapid
technological advances and constantly improving price/performance. As most of
the segments in which the Company operates continue to grow faster than the
industry as a whole, the Company is experiencing an increase in competition, and
it expects this trend to continue. This competition comes not only from the
Company's traditional UNIX workstation rivals and traditional supercomputing
competitors, but also from new sources including the personal computer industry.
Many of the Company's competitors have substantially greater technical,
marketing and financial resources and, in some segments, a larger installed base
of customers and a wider range of available applications software. Competition
may result in significant discounting and lower gross margins.
 
    DESKTOP SYSTEM STRATEGY  The Company has under development a desktop system
that will be based upon Intel microprocessors and the Windows NT operating
system. There can be no assurance that this system will be introduced, and in
any event the system will not account for any material revenues in fiscal 1998.
Success in this market segment will require that the Company adapt to the very
different requirements of this higher volume, lower margin market, including
lower-cost manufacturing and distribution, marketing to a broader audience in
markets that could extend beyond the Company's traditional markets, and new
approaches to customer interface and support. The Company will also be required
to manage a complex product transition and to support a product line including
multiple operating systems. In particular, although the Company plans to
continue to invest in and support its current line of UNIX/ MIPS-based
workstations, there is a risk that revenue from this business will be materially
reduced by the announcement of the new product. The Company believes that its
future success will depend in significant part on its making the right strategic
choices in this market segment and on executing its strategy effectively.
 
    IMPACT OF GOVERNMENT CUSTOMERS  A significant portion of the Company's
revenue is derived from sales to the U.S. government, either directly by the
Company or through system integrators and other resellers. Sales to the
government present risks in addition to those involved in sales to commercial
customers, including potential disruptions due to appropriation and spending
patterns and the government's reservation of the right to cancel contracts for
its convenience.
 
    EXPORT REGULATION  The Company's sales to foreign customers are subject to
export regulations. Sales of many of the Company's high-end products require
clearance and export licenses from the U.S. Department of Commerce under these
regulations. The Departments of Commerce and Justice are currently investigating
the Company's compliance with the export regulations in connection with the sale
of several computer systems to a customer in Russia in fiscal 1997. The Company
believes that it has complied in all material respects with all applicable laws
and that this matter will be resolved without a significant adverse effect on
the Company's business. However, there is no assurance that this matter will not
have an unforeseen outcome that could impair the conduct of the Company's
business outside the United States.
 
    The Company's international sales would also be adversely affected if such
regulations were tightened, or if they are not modified over time to reflect the
increasing performance of the Company's products.
 
    DEVELOPMENT AND ACCEPTANCE OF MIPS RISC ARCHITECTURE  Most of the Company's
system products incorporate microprocessors based upon the Company's MIPS RISC
microprocessor architecture. The
 
                                       17
<PAGE>
Company licenses the manufacturing and distribution rights to these
microprocessors to selected semiconductor manufacturing companies. The Company
believes that the continued development and broad acceptance of the MIPS
architecture are critical to its future success.
 
    INTELLECTUAL PROPERTY  The Company routinely receives communications from
third parties asserting patent or other rights covering the Company's products
and technologies. Based upon the Company's evaluation, it may take no action or
it may seek to obtain a license. In any given case there is a risk that a
license will not be available on terms that the Company considers reasonable, or
that litigation will ensue. The Company currently has patent infringement
lawsuits pending against it. The Company expects that, as the number of hardware
and software patents issued continues to increase, and as the Company's business
grows, the volume of these intellectual property claims will also increase.
 
    EMPLOYEES  The Company's future success depends in part on its ability to
continue to attract, retain and motivate highly qualified technical, marketing
and management personnel, who are in great demand.
 
    BUSINESS DISRUPTION  The Company's corporate headquarters, including most of
its research and development operations and manufacturing facilities, are
located in the Silicon Valley area of Northern California, a region known for
seismic activity. Operating results could be materially affected by a
significant earthquake. The Company is predominantly self-insured for losses and
business interruptions of this kind.
 
    GLOBAL FINANCIAL MARKET RISKS  The Company's business and financial results
are affected by fluctuations in world financial markets, including foreign
currency exchange rates and interest rates. The Company's hedging policy
attempts to reduce some of these risks, based on management's best judgment of
the appropriate tradeoffs among risk, opportunity and expense. The Company
regularly reviews its overall hedging policies, and it continually monitors its
hedging activities to ensure that they are consistent with the Company's policy
and are appropriate and effective in light of changing market conditions.
Management may as part of this review determine at any time to change its
hedging policies. Though the Company intends for its risk management policy to
be comprehensive, there are inherent risks which may be only partially offset by
the Company's program should there be unfavorable movements in either foreign
exchange or interest rates.
 
    Because a significant portion of the Company's revenue is from sales outside
the United States, and many key components are produced outside the United
States, the Company's results can be significantly affected by changes in
foreign currency exchange rates or weak economic conditions in the foreign
markets in which the Company distributes its products. The Company is primarily
exposed to changes in exchange rates on the German mark, British pound, Japanese
yen, French franc, and Korean won. When the U.S. dollar strengthens against
these currencies, the value (as expressed in U.S. dollars) of non-U.S. dollar-
based sales and costs decrease. The opposite happens when the U.S. dollar
weakens. Because the Company is a net receiver of currencies other than the U.S.
dollar, it benefits from a weaker dollar and is adversely affected by a stronger
dollar relative to major currencies worldwide. Accordingly, a strengthening of
the U.S. dollar tends to affect negatively the Company's revenue and gross
margins.
 
    The Company's currency hedging program currently involves hedging (i) net
non-U.S. dollar monetary assets and liabilities and generally all server backlog
where the delivery cycle is expected to exceed three months using currency
forward contracts and (ii) a significant portion of anticipated quarterly
revenue using currency options which expire within each fiscal quarter. The
Company has generally not hedged capital expenditures, investments in
subsidiaries or inventory purchases. However, because the Company procures
inventory and its international operations incur expenses in local currencies,
the financial effects of fluctuations in the U.S. dollar values of non-U.S.
dollar-based transactions frequently mitigate or tend to offset each other on a
consolidated basis.

    At June 30, 1997, the Company had a notional amount of $296 million in
currency forward contracts related to net non-U.S. dollar monetary assets and
liabilities and server backlog. Approximately $269 million of such currency
forward contracts expire within two months of fiscal year end and all but $8
million expire during fiscal 1998. The currency forward contracts are
principally denominated in German marks ($71 million), British pounds ($38
million) and Japanese yen ($36 million), with the remainder distributed across
over twenty other currencies. At June 30, 1997, the aggregate fair value of the
Company's currency forward agreements was $0.1 million.
 
    The Company also had $55 million in Japanese yen denominated borrowings, $20
million in Swiss franc denominated borrowings and $4 million in other foreign
currency denominated borrowings at June 30, 1997. The aggregate fair value of
these borrowings at June 30, 1997 was $79 million.
 
    The Company's investment securities and substantially all of its debt
instruments carry fixed rates of interest over their respective maturity terms.
The Company does not currently use derivatives, such as swaps, to alter the
interest characteristics of its investment securities or its debt instruments.
The Company's investment securities represented 6% of total assets at June 30,
1997. Investment securities aggregating $110 million mature during fiscal 1998
at fixed rates averaging 5.51%, and investment securities aggregating $87
million mature in fiscal 1999 at fixed rates averaging 5.34%. The aggregate fair
value of the Company's investment securities at June 30, 1997 equaled its
carrying value of $197 million. With respect to its interest bearing liabilities
at June 30, 1997, $41 million of the Company's $45 million in short-term
borrowings were in reverse repurchase agreements (average rate of 6.10%) that
were repaid in July 1997 and all but $20 million of its $380 million in
long-term borrowings are at fixed rates (average rate of 4.45%). The aggregate
future principle cash flow and fair value of the Company's borrowings at June
30, 1997 were $664 million and $414 million, respectively. The differential
between the future cash flow and fair value is primarily attributable to the
Company's Zero Coupon Convertible Subordinated Debentures due 2013 with an
ultimate maturity value of $455 million and a fair value of $223 million.

                              REPORT OF MANAGEMENT
 
To Our Stockholders:
 
    The Company's management is responsible for the preparation and integrity of
the financial information presented in the accompanying consolidated financial
statements. The financial statements were prepared in conformity with generally
accepted accounting principles and reflect management's estimates and judgments
as required.
 
    The Company's consolidated financial statements have been audited by Ernst &
Young LLP, a firm of independent auditors, whose appointment was approved by the
Company's stockholders. Their accompanying report is based on procedures
performed in accordance with generally accepted auditing standards, including
tests of the accounting records and other auditing procedures as they considered
necessary.
 
    The Company's management maintains a system of internal control and related
policies and procedures designed to provide reasonable assurance that assets are
safeguarded, transactions are properly executed in accordance with management's
authorization, and accounting records may be relied upon for the preparation of
financial statements and other financial information. Limitations exist in any
system of internal control based upon the recognition that the cost of the
systems should not exceed the benefits derived. The system is continuously
monitored by direct management review and by internal auditors who conduct a
program of audits throughout the Company. Ernst & Young LLP, as part of the
audit of the Company's consolidated financial statements, considers that
internal control structure to determine the nature, timing, and extent of its
audit tests. Management believes that the Company's system of internal control
is adequate to accomplish the objectives discussed herein.
 
    The Audit Committee of the Board of Directors, composed solely of directors
who are not officers of the Company, is responsible for monitoring and
overseeing the quality of the Company's accounting and reporting policies,
internal controls and other matters deemed appropriate. Based on the nature of
the matters under review, the independent and internal auditors, as well as
certain officers and employees, attend all or part of the Audit Committee
meetings. The Audit Committee has direct and private access to both internal and
external auditors and reviews the performance of Ernst & Young LLP in their
audit of the Company's financial statements and evaluates their independence and
professional competence.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
To The Board Of Directors And Stockholders Of Silicon Graphics, Inc.
 
    We have audited the accompanying consolidated balance sheets of Silicon
Graphics, Inc. as of June 30, 1997 and 1996, and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended June 30, 1997. Our audits also included the
financial statement schedule noted in the index at Item 14(a)(2). These
financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material aspects, the consolidated financial position of Silicon
Graphics, Inc. at June 30, 1997 and 1996, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
June 30, 1997, in conformity with generally accepted accounting principles.
Also, in our opinion, the related financial statement schedule, when considered
in relation to the basic financial statements taken as a whole, presents fairly
in all material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. NATURE OF OPERATIONS
 
    Silicon Graphics, Inc. ("Silicon Graphics" or the "Company") is a leader in
high-performance computing. The Company's broad range of workstations and
graphics servers deliver advanced 3D graphics and computing capabilities for
engineering and creative professionals. Silicon Graphics and Cray
Research-branded servers are the market leaders in technical computing
applications. The Company's highly scalable servers also have a growing presence
in the enterprise market, with a particular emphasis on Internet, large
corporate data and telecommunications applications. The Company's products are
primarily manufactured in Mountain View, California, Chippewa Falls, Wisconsin
and near Neuchatel, Switzerland. The Company distributes its products through
its direct sales force, as well as through indirect channels including resellers
and distributors. Product and other revenue consists primarily of revenue from
system and software product shipments, as well as the sale of software
distribution rights, system leasing, technology licensing agreements and
non-recurring engineering ("NRE") contracts. Service revenue results primarily
from customer support and maintenance contracts.
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    PRINCIPLES OF CONSOLIDATION  The consolidated financial statements include
the accounts of the Company and its wholly-owned subsidiaries after elimination
of significant intercompany transactions and balances. The Company acquired Cray
Research, Inc. in a merger effected in the fourth quarter of fiscal 1996. The
Cray Research operating results were consolidated with those of the Company at
April 2, 1996, and the consolidated results reflect a 25% minority interest in
the Cray Research operating results for the period from April 2, 1996 through
June 30, 1996. The Company acquired Alias Research Inc. ("Alias") and Wavefront
Technologies, Inc. ("Wavefront") in mergers effected in the fourth quarter of
fiscal 1995. These mergers were accounted for as a pooling of interests and as
such, all periods prior to fiscal 1995 were restated. The consolidated financial
statements for fiscal 1995 were not restated to adjust Alias's and Wavefront's
fiscal year-ends to that of the Company. Thus, fiscal 1995 includes the
Company's results of operations and balance sheet data on a June 30 fiscal year
basis, Alias' on a January 31 fiscal year basis, and Wavefront's on a calendar
year basis. Certain amounts for prior years have been reclassified to conform to
current year presentation.
 
    FOREIGN CURRENCY TRANSLATION  The Company translates the assets and
liabilities of its foreign subsidiaries stated in local functional currencies to
U.S. dollars at the rates of exchange in effect at the end of the period.
Revenues and expenses are translated using rates of exchange in effect during
the period. Gains and losses from currency translation are included in
stockholders' equity. Currency transaction gains or losses are recognized in
current operations and, net of hedging gains or losses, have not been
significant to the Company's operating results in any period.
 
    USE OF ESTIMATES  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results inevitably will differ from those estimates,
and such differences may be material to the financial statements.
 
    CASH EQUIVALENTS AND MARKETABLE INVESTMENTS  Cash equivalents consist of
high quality money market instruments with original maturities of 90 days or
less. Short-term marketable investments consist of high quality money market
instruments with original maturities greater than 90 days, but less than one
year, and are stated at fair value. Other marketable investments consist
primarily of high quality debt securities with maturities greater than one year
and less than two years, and are stated at fair value. At June 30, 1997 and
1996, the Company's cash equivalents and marketable investments are all
classified as available-for-sale.
 
                                       27
<PAGE>
    The cost of securities when sold is based upon specific identification.
Realized gains and losses and declines in value judged to be
other-than-temporary on available-for-sale securities are included in interest
income and other, net. Unrealized gains and losses (net of tax) on securities
classified as available-for-sale are included in stockholders' equity.
 
    FAIR VALUES OF FINANCIAL INSTRUMENTS  Fair values of cash equivalents and
short-term debt approximate cost due to the short period of time to maturity.
Fair values of marketable investments, long-term debt, foreign exchange forward
contracts and interest swaps are based on quoted market prices or pricing models
using current market rates.
 
    DERIVATIVE FINANCIAL INSTRUMENTS  Silicon Graphics uses derivatives to
moderate some of its financial market risks including, foreign currency and
interest rate market exposures of certain assets, liabilities and other
obligations. The Company does not hold or issue any derivative instruments for
trading purposes. The Company's accounting policies for these instruments are
based on its designation of such instruments as hedging transactions. The
criteria the Company uses to designate an instrument as a hedge include its
effectiveness in risk reduction and one-to-one matching of derivative
instruments to underlying transactions. Gains and losses on currency forward
contracts that hedge firmly committed customer transactions are deferred and
recognized in revenue in the same period that the underlying transactions are
settled. Gains and losses on currency forward contracts that hedge existing
assets and liabilities are recognized in interest and other income, net, in the
same period as losses and gains on the underlying transactions are recognized
and generally offset. Gains and losses on any derivatives not meeting the above
criteria would be recognized in income in the current period. The differential
between fixed and floating rates to be paid or received on interest rate swaps
is accrued and recognized as an adjustment to interest expense over the life of
the agreements. The related amount payable or receivable is included in other
current assets or accrued liabilities.
 
    INVENTORIES  Manufacturing inventories are stated at the lower of cost
(first-in, first-out) or market. Marketing inventories are stated at cost less
depreciation generally based on a two-year life.
 
    PROPERTY AND EQUIPMENT  Property and equipment is stated at cost and
depreciation is computed using the straight-line method. Useful lives of two to
seven years are used for machinery and equipment and furniture and fixtures;
leasehold improvements are amortized over the shorter of their useful lives or
the term of the lease. The Company's buildings and improvements are depreciated
over eight to forty years.
 
    OTHER ASSETS  Included in other assets are intangible assets related to the
acquisition of Cray Research in fiscal 1996, and goodwill associated with the
acquisition of Silicon Graphics World Trade Corporation in fiscal 1991.
Amortization of these purchased intangibles and goodwill is provided on a
straight-line basis over the respective useful lives of the assets ranging from
four to twenty years. Also included in other assets are purchased technologies
and spare parts that are generally amortized on a straight-line basis over the
course of their respective useful lives ranging from two to ten years, as well
as deferred tax assets.
 
    Effective July 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets
and Long-Lived Assets to Be Disposed Of ("SFAS 121"). The adoption of SFAS 121
has not had a material impact upon the Company's financial position or results
of operations.
 
    REVENUE RECOGNITION  Product revenue is generally recognized when the
product is shipped to the customer and the Company has no additional performance
obligations. Sales of certain high performance systems, including most Cray
Research-branded systems, are made on the basis of contracts that include
acceptance criteria. In these instances, revenue (net of trade-in allowances) is
recognized upon acceptance by the customer or independent distributor.
 
                                       28
<PAGE>
    Initial software fees are recognized when the product has been shipped,
provided that the Company has no additional performance obligations. Revenue
recognition under technology agreements is dependent on the nature and level of
effort required to deliver and/or support the technology transfer. Generally,
technology revenue is recognized upon the completion of contract requirements or
milestones.
 
    Revenue related to future commitments under service contracts is deferred
and recognized ratably over the related contract term.
 
    PRODUCT WARRANTY  The Company provides at the time of sale for the estimated
cost to warrant its products against defects in materials and workmanship for a
period of up to one year.
 
    ADVERTISING COSTS  The Company accounts for advertising costs as expense in
the period in which they are incurred. Advertising expense for the years ended
June 30, 1997, 1996 and 1995 was $42.5 million, $37.5 million and $16.9 million,
respectively.
 
    PER SHARE DATA  Primary earnings per share are computed using the weighted
average number of shares of common stock and dilutive common stock equivalents
outstanding during the period. Dilutive common share equivalents include stock
options or warrants using the treasury stock or modified treasury stock method
(whichever applies) and, if dilutive, convertible securities on an
as-if-converted basis. For the purpose of calculating earnings per share, the
Company's convertible preferred stock is considered to be a common stock
equivalent. Fully diluted earnings per share are substantially the same as
reported earnings per share.
 
    In March 1997, the Financial Accounting Standards Board issued Statement No.
128, Earnings Per Share ("SFAS 128"), which modifies existing guidance for
computing earnings per share and requires the disclosure of basic and diluted
earnings per share. Under the new standard, basic earnings per share is computed
as earnings available to common stockholders divided by weighted average shares
outstanding excluding the dilutive effects of stock options and other
potentially dilutive securities. Diluted earnings per share includes the
dilutive effect of these securities. The effective date of SFAS 128 is December
15, 1997 and early adoption is not permitted. The Company intends to adopt SFAS
128 during the quarter ended December 31, 1997. Had the provisions of SFAS 128
been applied to the Company's results of operations for each of the three years
in the period ended June 30, 1997, the Company's basic earnings per share would
have been $0.44, $0.70 and $1.44 per share, respectively, and its diluted
earnings per share would have been $0.43, $0.65 and $1.26 per share,
respectively.
 
    STOCK COMPENSATION  In fiscal 1997, the Company implemented the disclosure
requirements of the Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation ("SFAS 123"). Under SFAS 123, the
Company will continue to account for stock-based employee compensation
arrangements under the intrinsic value method prescribed by Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees ("APB
25"), and will provide pro forma disclosures of net income and earnings per
share as if the fair value basis method prescribed by SFAS 123 had been applied
in measuring employee compensation expense.
 
    RECENT ACCOUNTING PRONOUNCEMENTS  In June 1997, the Financial Accounting
Standards Board issued Statement No. 130, Reporting Comprehensive Income ("SFAS
130"), and Statement No. 131, Disclosures about Segments of an Enterprise and
Related Information ("SFAS 131"). The Company is required to adopt these
Statements in fiscal 1999. SFAS 130 establishes new standards for reporting and
displaying comprehensive income and its components. SFAS 131 requires disclosure
of certain information regarding operating segments, products and services,
geographic areas of operation and major customers. Adoption of these Statements
is expected to have no impact on the Company's consolidated financial position,
results of operations or cash flows.
 
NOTE 3. BUSINESS COMBINATIONS
 
    ACQUISITION OF CRAY RESEARCH  On April 2, 1996, Silicon Graphics acquired
approximately 75% of the outstanding shares of common stock of Cray Research for
cash. On June 30, 1996, the Company acquired
 
                                       29
<PAGE>
the remaining outstanding Cray Research shares in a merger by exchanging one
share of Silicon Graphics common stock for each remaining share of Cray Research
common stock. Silicon Graphics also assumed the outstanding Cray Research
employee stock options. The aggregate purchase price (including direct
acquisition costs) was approximately $767 million in cash, common stock and the
value associated with options to purchase the Company's common stock. The
Company has accounted for the acquisition using the purchase method.
 
    The following is a summary of the purchase price allocation (in millions):
 
<TABLE>

                                                                      ---------
                                                                      $   766.8
                                                                      ---------
                                                                      ---------
</TABLE>
 
    Intangible assets include $24.5 million of completed technology and an
aggregate of $59.8 million for customer lists, trade name and
workforce-in-place. Completed technology has been assigned a four-year life,
workforce-in-place a five-year life and customer lists and trade name 15-year
lives.
 
    The accrual for exit costs includes only those direct costs related to
exiting facilities and operations acquired from Cray Research and does not
include any costs related to modifications of the previous Silicon Graphics
business. The composition of costs related to the exit activities were as
follows (in millions): non-cancelable lease commitments after closure and
related costs--$16.6; severance and related costs--$20.5; and other costs--$2.3.
Except for approximately $6 million in remaining lease commitments, severance
obligations and other assumed obligations, the activities contemplated in the
$39.4 million accrual for exit costs have been completed at June 30, 1997.
During fiscal 1997, cash outlays related to exit activities were approximately
$20 million. The excess of the original accrual for exit costs over the actual
amounts incurred and currently expected to be incurred will be amortized over
the combined average acquired asset life.
 
    The $98.2 million allocated to acquired in-process technology was expensed
in fiscal 1996 as required under generally accepted accounting principles.
 
    The unaudited pro forma combined condensed results of operations of the
Company for fiscal 1996 and 1995, had the acquisition occurred at the beginning
of each fiscal year presented and which eliminates the non-recurring charges,
are as follows (in thousands, except per share amounts):

</TABLE>
 
    The unaudited pro forma combined results for fiscal 1996 and 1995 exclude
the effects of the write-off of acquired in-process technology and other merger
costs of approximately $102 million, as such amounts are non-recurring. In
addition to combining the historical results of operations of the two companies,
the pro forma calculations include the estimated effect on the Company's
historical results of operations from adjustments to the historical carrying
values of Cray Research inventories and property, plant and equipment;
intangible asset amortization; and loss of interest income as a result of making
the acquisition.
 
    The unaudited pro forma information is presented for illustrative purposes
only and is not necessarily indicative of the operating results that would have
occurred had the transaction been completed at the beginning of the periods
indicated, nor is it necessarily indicative of future operating results.

    MERGERS WITH ALIAS AND WAVEFRONT  On June 15, 1995, the Company merged with
Alias and Wavefront. Alias and Wavefront outstanding common stock was converted
to Silicon Graphics common stock at per share rates of .90 and .49,
respectively. Silicon Graphics issued 14,100,577 shares in connection with the
mergers. The mergers were accounted for as a pooling of interests and,
accordingly, the Company's consolidated financial statements and related notes
thereto have been restated to include the results of Alias and Wavefront for all
periods presented. Adjustments to combine these entities, consisting primarily
of intercompany transactions, were not significant.
 
    The Company incurred costs in connection with the mergers and consolidation
of operations. Included in the accompanying consolidated statement of operations
for fiscal 1995 are merger-related expenses totaling approximately $22 million,
consisting primarily of charges for transaction and professional fees, personnel
severance costs, and elimination of duplicate facilities.

    FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK  The notional principal
amounts of the Company's foreign exchange instruments at June 30, 1997 and 1996
were $296 million and $512 million, respectively. The notional principal amounts
of the interest rate swap agreements at June 30, 1997 and 1996 were $0 and
approximately $200 million, respectively. The notional principal amounts for
off-balance-sheet instruments provide one measure of the transaction volume
outstanding at year end, and do not represent the amount of the Company's
exposure to credit loss or market risk. Credit risk is the Company's gross
exposure to potential accounting loss on these transactions if all
counterparties failed to perform as agreed at the contracted rates and contracts
had to be replaced at rates prevailing at each respective date. The Company
controls credit risk through credit approvals, limits and monitoring procedures.
Credit rating criteria are similar to those for investments.
 
    The Company transacts business in various foreign currencies, including the
major European currencies and the Japanese yen. The Company has established
revenue and balance sheet hedging programs to protect against reductions in
value and volatility of future cash flows caused by changes in foreign exchange
rates. The Company uses derivatives in the form of currency forward contracts
and currency options in its programs. All currency forward contracts related to
recorded transactions expire within two years. All currency forward contracts
related to firmly committed customer transactions expire within two and one-half
years. All currency options open and close within a fiscal quarter. Deferred
gains and losses on contracts related to firm commitments were immaterial at
June 30, 1997 and 1996.
 
    The Company entered into an interest rate swap agreement to reduce the
impact of changes in interest rates on its floating rate long-term debt. This
interest rate swap agreement reflected the gross proceeds of its Zero Coupon
Subordinated Debentures (see Note 9). This agreement expired in November 1996.

NOTE 5. CONCENTRATION OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to concentration
of credit risk consist principally of cash investments, currency forward
contracts and trade receivables. The Company places its investments and
transacts its currency forward contracts with high-credit-quality counterparties
and, by policy, limits the amount of credit exposure to any one counterparty.
The Company generally does not require collateral. The credit risk on
receivables due from counterparties related to currency forward contracts is
immaterial at June 30, 1997 and 1996. The Company performs ongoing credit
evaluations of its customers and except in connection with the sales of
supercomputers, generally does not require collateral. The Company maintains
reserves for potential credit losses and such losses have been within
management's expectations.

<PAGE>
NOTE 6. CONCENTRATIONS OF OTHER RISKS
 
    MATERIALS  Most of the Company's products incorporate components that are
available from only one or from a limited number of suppliers. Many of these
components are custom designed and manufactured, with lead times from order to
delivery that can exceed 90 days. Shortages of various essential materials could
occur due to interruption of supply or increased demand in the industry. If the
Company were unable to procure certain such components, it could affect the
Company's ability to meet demand for its products which would have an adverse
effect upon its results.
 
    INTERNATIONAL OPERATIONS  Because approximately half of the Company's
revenue is derived from sales outside the United States, and many key components
are produced outside the United States, the Company's results could be
negatively affected by such factors as changes in foreign currency exchange
rates, trade protection measures, longer accounts receivable collection
patterns, and changes in regional or worldwide economic or political conditions.
The risks of its international operations are mitigated in part by the Company's
foreign exchange hedging program and by the extent to which the Company's sales
and manufacturing activities are geographically distributed.
 
    The Company's sales to foreign customers also are subject to export
regulations, with sales of most of the Company's high-end products requiring
clearance and export licenses from the U.S. Department of Commerce. These
regulations are currently under review by the U.S. government. The Company's
export sales would be adversely affected if such regulations were tightened, or
if they are not modified over time to reflect the increasing performance of the
Company's products. The Departments of Commerce and Justice are currently
reviewing the Company's compliance with the export control regulations in
connection with the shipment of several computer systems to a customer in the
Russian Federation in fiscal 1997. The Company believes it has complied in all
material respects with all applicable laws. However, if the Company's export
privileges were limited or denied, the Company's results would be adversely
affected.

    The Company also has an unsecured $250 million revolving credit facility
that expires in April 1999. There were no cash borrowings under this facility at
June 30, 1997. Interest on borrowings is based upon either a prime rate, LIBOR
rate or competitive bid rate at the Company's option. Under this credit
facility, the Company is subject to certain commitment and utilization fees on
the unused portion of the committed amount. Fees incurred were not material
during the last three fiscal years. Covenants governing the credit facility
require the maintenance of certain financial ratios. At June 30, 1997, the
Company was in compliance with these covenants.

    In November 1993, the Company issued Zero Coupon Convertible Subordinated
Debentures (the "Zero Coupon Debentures") with an ultimate maturity amount of
$455 million. Effective November 2, 1998, the Zero Coupon Debentures will be
redeemable at any time, at the option of the Company, at redemption prices equal
to the issue price ($439.77 per debenture) plus accrued original issue discount
to the date of redemption. At the option of the holder, each Zero Coupon
Debenture is convertible into 16.269 shares of common stock of the Company at
any time. Also at the option of the holder, the Zero Coupon Debentures will be
purchased by the Company on November 2, 1998, November 2, 2003 or November 2,
2008, at purchase prices equal to the issue price plus accrued original issue
discount to such purchase date. The Company, at its option, may elect to pay any
such purchase price in cash or shares of common stock, or any combination
thereof. The Zero Coupon Debentures are redeemable at the option of the holder
in the event of the sale of all, or substantially all, of the Company's common
stock for consideration other than common stock traded on a U.S. exchange or
approved for quotation on the Nasdaq National Market. See Note 20 regarding the
Company's September 1997 exchange of new Senior Convertible Notes for its
outstanding Zero Coupon Debentures.
 
    Related to the Debentures, the Company had a receive fixed, pay floating
interest rate swap agreement on a notional amount of $200.1 million that expired
in November 1996.
 
    In connection with the Cray Research acquisition, the Company assumed the
Cray Research Convertible Subordinated Debentures. These debentures are
convertible into the Company's common stock at a
 
                                       34
<PAGE>
conversion price of $78 per share at any time prior to maturity and may be
redeemed at the Company's option at a price of 100%. In 1994 Cray Research
repurchased a portion of the debentures with a face value of $23.0 million. The
repurchase satisfied the first four required annual sinking fund payments of
$5.8 million originally scheduled for the years 1997 through 2000. Remaining
annual sinking fund payments of $5.8 million each are scheduled from 2001 to
2010 with a final maturity payment of $24.5 million in 2011.
 
    Principal maturities of long-term debt at June 30, 1997, are as follows (in
millions): 1998--$8.2; 1999--$3.9; 2000--$2.7; 2001--$1.9; 2002--$54.4; and
$309.1, thereafter.

    Future minimum lease rents on noncancelable sales-type lease agreements at
June 30, 1997 are as follows (in millions): 1998--$15.3; 1999--$8.3; 2000--$6.3;
and 2001--$1.2.
 
NOTE 11. LEASING ARRANGEMENTS AS LESSEE
 
    The Company leases certain of its facilities and some of its equipment under
non-cancelable operating lease arrangements.
 
    Future minimum annual lease payments under operating leases, net of
subleases and rental income, at June 30, 1997, were as follows (in millions):
1998--$84.8; 1999--$70.6; 2000--$56.7; 2001--$41.1; 2002-- $32.5; and $218.6,
thereafter. Remaining lease commitments for facilities vacated as a result of
the acquisition of Cray Research are included in the preceding payment amounts.
Future payments associated with these leases were provided for in the Company's
exit cost accrual (see Note 3) and therefore do not represent future operating
expenses.
 
    Aggregate operating lease rent expense was (in millions): $97.7, $76.7 and
$49.6, in fiscal 1997, 1996 and 1995, respectively.
 
    Under one of its lease agreements, the Company is contingently liable for
the residual value of five buildings at the end of their lease terms. The lease
for one of the buildings expires in 2000 and the lease for an additional four
buildings expires in 2002. However, the Company has the option to extend these
leases for an additional 35 years after expiration. If at the end of the final
lease renewal, or upon the Company's option to terminate the lease at any time,
the Company does not purchase the property or arrange a third-party purchase,
then the Company would be obligated to the lessor for a guaranteed payment equal
to a specified percentage of the lessor's purchase price for the properties. The
Company would also be obligated to the lessor for all or some portion of this
amount if the price paid by a third party for the property is below a specified
percentage of the lessor's purchase price. The total amount related to the five
properties, for which the Company would be contingently liable, is approximately
$93.4 million at the end of the lease terms.

NOTE 12. STOCKHOLDERS' EQUITY
 
    PREFERRED STOCK TRANSACTIONS  NKK Corporation ("NKK") of Japan, through a
wholly-owned U.S. subsidiary, owns 17,500 shares of Series A Convertible
Preferred Stock. The preferred stock pays a 3% cumulative annual dividend, has
preference upon liquidation in the amount of the purchase price and has
aggregate voting rights equivalent to 1,400,000 shares of common stock. The
preferred stock is convertible into the common stock of the Company at certain
times at the then-current price of the common stock. The preferred stock is
perpetual, but is subject to redemption at the option of the Company at certain
times if the market price of the common stock is below $8.75 per share.
 
    STOCK AWARD PLANS  The Company has various stock award plans which provide
for the grant of incentive and nonstatutory stock options and the issuance of
restricted stock to employees. Incentive stock options are granted at not less
than the fair market value on the date of grant; the prices of nonstatutory
stock option grants and restricted stock are determined by the board of
directors. Under the plans, options and restricted stock generally vest over a
fifty-month period from the date of grant. Under one of the plans, the number of
shares available for grant or issuance will be automatically increased on July
1, 1997 by a number of shares equal to 3.5% of the total common shares issued
and outstanding on the preceding June 30.
 
    In addition, the Company has a Directors' Stock Option Plan which allows for
the grant of nonstatutory stock options to nonemployee directors at not less
than the fair market value at the date of grant. Eligible directors are granted
an option to purchase 30,000 shares of common stock on the date of their initial
election as a director. On November 1 of each year, each eligible director is
granted an option to purchase an additional 10,000 shares of common stock. These
options generally vest in installments over a four year period. At June 30,
1997, 863,100 shares were available for future option grants under the
Directors' Stock Option Plan.

    In fiscal 1997, the Company effected an option exchange program to allow
employees (excluding senior executives) to exchange their out-of-the-money stock
options for a smaller number of new options at a more favorable exercise price.
Under the exchange program, one new option could be obtained for every 1.25 to 2
canceled options. The new options, which have an exercise price equal to
$18.875, the fair value on the date of exchange, will vest over the longer of

    STOCK PURCHASE PLAN  The Company has an employee stock purchase plan under
which eligible employees may purchase stock at 85% of the lower of the closing
prices for the stock at the beginning of a twenty four-month offering period or
the end of each six-month purchase period. The purchase periods generally begin
in May and November. Purchases are limited to 10% of each employee's
compensation. At June 30, 1997, 14,798,046 shares had been issued under the plan
and 6,261,954 shares were reserved for future issuance.
 
    PRO FORMA INFORMATION  The Company has elected to follow APB 25 in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under SFAS 123 requires the use
of option valuation models that were not developed for use in valuing employee
stock options. Under APB 25, no compensation expense is recognized in the
Company's financial statements unless the exercise price of the Company's
employee stock options is less than the market price of the underlying stock on
the date of grant. Total compensation expense recognized in the Company's
financial statements for stock-based awards under APB 25 for fiscal 1997 and
1996 was $5.4 million and $4.0 million, respectively.
 
    Pro forma information regarding net income and earnings per share has been
determined as if the Company had accounted for its employee stock options and
employee stock purchase plan under the fair value method prescribed by SFAS 123.
The fair value of options granted in fiscal 1997 and 1996 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
 
                                       38
<PAGE>
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 the fair value of its options.
 
    The weighted average estimated fair value of employee stock options granted
at grant date market prices during fiscal 1997 and 1996 was $5.94 and $11.48 per
share, respectively. The weighted average exercise price of employee stock
options granted at grant date market prices during fiscal 1997 and 1996 was
$20.56 and $29.24 per share, respectively. The weighted average estimated fair
value of employee stock options granted at below grant date market prices during
fiscal 1997 and 1996 was $13.54 and $16.68 per share, respectively. The weighted
average exercise price of employee stock options granted at below grant date
market prices during fiscal 1997 and 1996 was $12.56 and $13.44 per share,
respectively. The weighted average fair value of restricted stock granted during
fiscal 1997 and 1996 was $18.93 and $27.45 per share, respectively. The weighted
average estimated fair value of shares granted under the Stock Purchase Plan
during fiscal 1997 and 1996 was $7.06 and $15.30 per share, 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 per share amounts):

    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.
Because SFAS 123 is applicable only to options granted subsequent to June 30,
1995, the pro forma effect will not be fully reflected until 1999.
 
    STOCKHOLDER RIGHTS PLAN  The Company has a stockholder rights plan (the
"Rights Plan") which provides existing stockholders with the right to purchase
one one-thousandth (0.001) preferred share for each share of common stock held
in the event of certain changes in the Company's ownership. The Rights Plan may
serve as a deterrent to certain abusive takeover tactics which are not in the
best interests of stockholders.
 
    STOCK REPURCHASE PROGRAM  On October 19, 1995, the Company announced that
its board of directors had authorized the repurchase of up to 7.0 million shares
of its common stock, either in the open market or in private transactions. The
Company has purchased approximately 2.5 million shares since the commencement of
the repurchase program at an average price of approximately $31.00 per share.
Repurchased shares are available for use under the Company's employee stock
plans and for other corporate purposes. The Company suspended its stock
repurchases when the agreement to acquire Cray Research was announced in
February 1996. Stock repurchases may be resumed at any time.
 
    COMMON SHARES RESERVED  The Company has reserved in the aggregate 60,218,307
shares of common stock issuable upon conversion of all convertible subordinated
debentures, as well as shares issuable under its stock award and purchase plans.

    No provision for residual federal taxes has been made on approximately
$241.5 million of accumulated undistributed earnings of the Company's foreign
subsidiaries since it is the Company's intention to permanently invest such
earnings in foreign operations. The Company has been granted exemptions from tax
on income from certain manufacturing operations located outside the U.S. for
years through 2006. The cumulative income tax benefits attributable to the tax
status of this subsidiary are estimated to be $84.5 million at June 30, 1997.

    At June 30, 1997, the Company had federal net operating loss carryforwards
of approximately $215.5 million for United States federal income tax purposes
expiring in the years 2005 through 2011. At June 30, 1997, the Company also had
general business credit carryovers of approximately $5.4 million for United
States federal tax purposes, expiring in the years 1999 through 2010. In
addition, the Company had foreign tax credit carryforwards of approximately
$28.6 million which expire in the years 1998 through 2001, and a capital loss
carryforward of $3.3 million expiring in 2000.
 
    As a result of the acquisition by Silicon Graphics, Cray Research
experienced a "change in ownership" as defined under Section 382 of the Internal
Revenue Code and is subject to certain limitations on the utilization of its
pre-acquisition net operating loss and tax credit carryforwards. The Company has
provided a valuation allowance to offset the deferred tax asset relating to
foreign tax credits that may expire prior to utilization due to this annual
limitation. The valuation allowance for deferred tax assets of approximately
$59.9 million will be applied to reduce the noncurrent intangible assets related
to the acquisition of Cray Research if future tax benefits are subsequently
realized.

NOTE 15. BENEFIT PLANS
 
    401(k) RETIREMENT SAVINGS PLAN  The Company provides a 401(k) investment
plan covering substantially all of its U.S. employees. The plan provides for a
minimum 25 percent Company match of an employee's contribution up to a specified
limit, but allows for a larger matching subject to certain regulatory
limitations. The Company's matching contributions for fiscal 1997, 1996 and
1995, were $11.0 million, $4.7 million and $13.7 million, respectively.
 
    DEFERRED COMPENSATION PLAN  The Company has a Non-Qualified Deferred
Compensation Plan ("The Plan") that allows eligible executives and directors to
defer a portion of their compensation. The deferred
 
                                       42
<PAGE>
compensation, together with Company matching amounts and accumulated earnings,
is accrued but unfunded. Such deferred compensation is distributable in cash and
at June 30, 1997 and 1996, amounted to approximately $5 million and $3 million,
respectively. A participant may elect to receive such deferred amounts in one
payment or in annual installments no sooner than two years following each annual
election. Participant contributions are always 100% vested and Company matching
contributions vest as directed by the board of directors. There have been no
Company matching contributions to date.
 
NOTE 16. RELATED PARTY TRANSACTIONS
 
    The Company has from time to time engaged in significant transactions with
related parties in the ordinary course of business. Related parties have
included: Northrop Grumman Corporation and Chrysler Corporation, as a director
of both Northrop Grumman and Chrysler became a member of the Company's board of
directors in fiscal 1996; Tandem Computers, Incorporated, as a director of
Tandem is also on the Company's board of directors; Control Data Systems, Inc.
(CDSI) due to the Company's investment in common stock of CDSI through March 31,
1995; and NKK through its indirect ownership of 100% of Series A Convertible
Preferred Stock (see Note 12).
 
    Product and other revenue for the years ended June 30, 1997, 1996 and 1995
included, in the aggregate, sales to related parties in the amount of $77.9
million, $72.9 million and $119.6 million, respectively. Purchases and amounts
receivable from and amounts payable to such related parties were immaterial at
June 30, 1997, 1996 and 1995.

NOTE 18. CONTINGENCIES
 
    The Company is defending the lawsuits described below. The Company believes
that it has good defenses to the claims in each of these lawsuits and is
defending each of them vigorously.
 
    The Company is defending a securities class action lawsuit filed in U.S.
District Court for the Northern District of California in January 1996. The suit
alleges that the Company and certain of its officers and directors made material
misrepresentations and omissions during the period from September to December
1995. In May 1996, the District Court dismissed the securities class action with
prejudice. The plaintiffs' appeal to the U.S. Court of Appeals for the Ninth
Circuit is pending.
 
    The Company also is defending securities class action lawsuits involving
MIPS Computer Systems, Inc.("MIPS"), which the Company acquired in June 1992,
and Alias Research Inc., which the Company acquired in June 1995. The MIPS case,
which was filed in the U.S. District Court for the Northern District of
California in 1992, alleges that MIPS and certain of its officers and directors
made material misrepresentations and omissions during the period from January to
October of 1991. In September 1996, the U.S. Court of Appeals for the Ninth
Circuit reversed the summary judgment granted in defendants' favor in
 
                                       43
<PAGE>
June 1994. The Company's petition for review by the U.S. Supreme Court is
pending. The Alias case, which was filed in the U.S. District Court for the
District of Connecticut in 1991, alleges that Alias and certain of its officers
and directors made material misrepresentations and omissions during the period
from May 1991 to April 1992. Alias' motion to dismiss the amended complaint is
pending.
 
    The Company also is defending a patent infringement lawsuit filed by Martin
Marietta Corp. in the U.S. District Court for the Middle District of Florida in
September 1995. The Company has filed a counterclaim seeking to invalidate the
principal patent at issue in the lawsuit, and Martin Marietta has requested the
U.S. Patent and Trademark Office to re-examine the patent. The District Court
has set a trial date for the lawsuit in February 1998.
 
    The Company routinely receives communications from third parties asserting
patent or other rights covering the Company's products and technologies. Based
upon the Company's evaluation, it may take no action or it may seek to obtain a
license. There can be no assurance in any given case that a license will be
available on terms the Company considers reasonable, or that litigation will not
ensue.
 
    Management is not aware of any pending disputes, including those described
above, that would be likely to have a material adverse effect on the Company's
financial condition, results of operations or liquidity. However, management's
evaluation of the likely impact of these pending disputes could change in the
future.
 
NOTE 19. PENDING ACQUISITION
 
    In May 1997, the Company entered into an agreement, subject to certain
conditions to closing, to acquire ParaGraph International, Inc. ("ParaGraph"), a
software company, in exchange for cash and shares of the Company's common stock
for an aggregate purchase price of approximately $50 million, including direct
acquisition costs. The Company will account for the acquisition using the
purchase method. Acquired in-process technology is expected to be between $15
million and $20 million. The acquisition is expected to be consummated September
30, 1997.
 
NOTE 20. DEBT EXCHANGE
 
    On September 11, 1997, the Company exchanged its newly registered Senior
Convertible Notes (the "Senior Notes") due 2004 for approximately 98% of its
existing Zero Coupon Debentures pursuant to an exchange offer initiated in
August. The Senior Notes pay interest semi-annually at a rate of 5.25% and are
convertible into shares of common stock at a conversion price equal to $36.25
per share. The Senior Notes are redeemable at the option of the Company,
beginning in 2002, at varying prices based on the year of redemption. The Senior
Notes are redeemable at the option of the holder in the event of the sale of
all, or substantially all, of the Company's common stock for consideration other
than common stock traded on a U.S. exchange or approved for quotation on the
Nasdaq National Market. The aggregate principal amount of Senior Notes issued in
the exchange was $231 million, equal to the accreted value on the exchange offer
Expiration Date (September 4, 1997) of each $1,000 principal amount at maturity
of the Zero Coupon Debentures tendered in the exchange. Under current generally
accepted accounting principles, the exchange does not constitute an
extinguishment of debt and, accordingly, as a result of the exchange there will
be no change in the carrying value of the Company's debt. The Company recorded a
charge of approximately $2.6 million for the Senior Note issuance costs upon
closing.
