PART I

ITEM 1. BUSINESS

GENERAL

EMC Corporation and its subsidiaries ("EMC" or the "Company") design,
manufacture, market and support a wide range of hardware and software products
and provide services for the storage, management, protection and sharing of
electronic information. These integrated solutions enable organizations to
create an electronic information infrastructure, or what EMC calls an
E-Infostructure. EMC is the leading supplier of these solutions, which are
comprised of enterprise storage systems, networks, software and services. Its
products are sold to customers utilizing a variety of the world's most popular
computing platforms for key applications, including electronic commerce, data
warehousing and transaction processing. EMC believes these and other
information-intensive applications provide it with significant growth
opportunities.

The effective management, sharing, protection and availability of critical
information is a major challenge for organizations as the number, size and scope
of and reliance on computer systems continues to grow. To address this market
opportunity, EMC has introduced the Enterprise Storage Network, or "ESN." An EMC
ESN is a dedicated network connecting EMC storage systems and software to all
major computing platforms via various network protocols, including fibre
channel. An ESN provides the basis for an E-Infostructure by enabling customers
to consolidate all of their information resources for more effective and
efficient management, sharing and protection.

The Company's objective is to extend its position as the enterprise storage
solutions leader in the IT industry and to strengthen the EMC E-Infostructure as
the standard for networked storage. EMC develops its products by integrating
technologically advanced, industry standard components with Company-designed
hardware and software that the Company believes provide competitive advantages
for its customers.

The customers for the Company's products are located worldwide and represent
a cross section of industries and government agencies. EMC products continue to
be accepted widely by both existing customers and new accounts in all major
industries worldwide.

In 1999, the Company acquired Data General Corporation ("Data General"), a
leading provider of CLARiiON Fibre Channel storage systems and AViiON computer
systems. The Company integrated the CLARiiON product line into EMC's primary
storage line of business and formed a new Data General division to continue to
develop, market and service AViiON computers and related services.

EMC, a Massachusetts corporation, was incorporated in 1979 and has its
corporate headquarters at 35 Parkwood Drive, Hopkinton, Massachusetts.

PRODUCTS AND OFFERINGS

STORAGE SYSTEMS

EMC SYMMETRIX ENTERPRISE STORAGE SYSTEMS

The Company's flagship product line is the EMC Symmetrix Enterprise Storage
family of systems. The Company believes that the Symmetrix Enterprise Storage
systems offer the highest levels of functionality, performance and availability
in data centers and the high-end of the storage market. EMC's common hardware
architecture on which its Symmetrix products are based is called MOSAIC:2000, a
modular design and interface that allows new technologies to be rapidly
incorporated. This hardware architecture enables EMC to deliver advanced
technologies to market quickly while maintaining a consistent platform upon
which its customers can expand capacity, performance, connectivity and
functionality. This architectural hardware design has enabled the Company to
expand its Symmetrix products into existing markets and to enter new, strategic
markets quickly with proven storage products and services.

Since the introduction of the first Symmetrix model in 1991, EMC has
continued to enhance and increase the capabilities of the Symmetrix family,
including increasing the host connectivity capabilities and adding advanced
software functionality. The Company intends to continue to introduce new
versions of the Symmetrix systems with increased performance and other
capabilities.

The Company also continues to engage in research and development of new
hardware technology for the enterprise storage market.

EMC CLARIION FIBRE CHANNEL STORAGE SYSTEMS

The EMC CLARiiON Fibre Channel family of products represents a range of
flexible and scalable midrange storage systems for Microsoft Windows NT and UNIX
platforms. EMC CLARiiON Fibre Channel storage systems offer fast, scalable and
dependable storage solutions for applications in the distributed environments of
large enterprises and for emerging companies with moderate but rapidly growing
demands on the performance, availability and manageability of their storage
infrastructure.

The Company believes that the EMC CLARiiON Fibre Channel storage systems
offer storage with the highest performance and availability in the midrange
storage market. The Company intends to continue to introduce new versions of the
EMC CLARiiON systems with increased performance and other capabilities.

EMC CONNECTRIX ENTERPRISE STORAGE NETWORK SYSTEMS

The EMC Connectrix Enterprise Storage Network System, introduced in March
1999, is the industry's first fully integrated fibre channel network
connectivity solution. EMC Connectrix facilitates the connection of a large
number of servers to a single storage system through fibre channel links. EMC
Connectrix offers up to 64-port switched Fibre Channel (FC-SW) connectivity
between EMC Symmetrix Enterprise Storage systems, EMC CLARiiON Fibre Channel
storage systems and distributed servers. Connectrix systems quadruple the number
of servers that can connect to these systems, when compared with direct fibre
channel server-to-storage connections.

The Company believes that its EMC Connectrix systems, combined with its
storage systems with fibre channel connectivity, facilitate the implementation
of the EMC ESN and enable customers to build an E-Infostructure in which a
single pool of storage will handle all information storage requirements of even
the largest, most complex organizations.

The Company intends to continue to introduce new versions of the EMC
Connectrix system with additional features and capabilities.

2

EMC CELERRA FILE SERVER

The EMC Celerra File Server is a network-attached storage system providing
high performance, high availability and scalability for enterprise file storage.
The system features EMC-developed software and hardware, known as Data Movers,
within a common enclosure and with a common management environment. The Data
Movers and management environment connect to Symmetrix Enterprise Storage
systems and external customer networks through a variety of interfaces. A file
server's purpose is to provide end users with the ability to access, update and
store common files to a central location directly from their desktop computer
without the need to utilize a general purpose server.

The Company intends to continue to introduce new versions of the EMC Celerra
File Server system with additional features and capabilities.

Revenue from enterprise storage systems (including Symmetrix, Connectrix and
Celerra products) represented approximately 60%, 58% and 56% of revenues in
1999, 1998 and 1997, respectively. Revenue from CLARiiON storage systems
represented approximately 6%, 8% and 11% of revenues in 1999, 1998 and 1997,
respectively.

ENTERPRISE STORAGE SOFTWARE

EMC offers highly innovative software that provides customers with superior
information management, sharing and protection capabilities. These capabilities
include enhanced backup/restore, disaster recovery, business continuance, data
migration and data movement. The Company's enterprise storage software is
intended to be used with its storage systems as well as with a variety of host
computers and applications developed by third parties. During 1999, the Company
introduced several new software products and enhancements to existing products.

EMC's information management software includes EMC Control Center, EMC
PowerPath and EMC VolumeLogix. Examples of information sharing software are
Symmetrix Enterprise Storage Platform (ESP) and EMC InfoMover. The Company's
information protection software includes Symmetrix Remote Data Facility (SRDF),
EMC TimeFinder and EMC Data Manager (EDM).

In August 1999, the Company announced its E-Infostructure Developers
Program, which makes certain of its application programming interfaces (APIs)
available to third-party independent software vendors (ISVs) to facilitate the
development and sale of software optimized to run on EMC systems. Customers are
then able to select from a wider range of software tools when deploying EMC
systems and to more easily integrate EMC systems into their existing software
environments.

EMC also sponsored the formation of the FibreAlliance in 1999. The
FibreAlliance is an independent standards group comprised of numerous hardware
and software companies. The goal of the FibreAlliance is to develop and
implement common methods for managing the heterogeneous fibre channel-based
networks of storage systems and computer servers, which EMC calls ESNs. The
FibreAlliance is submitting these methods to independent standards bodies for
consideration as an industry-wide standard.

The Company finalized its acquisition of software developer Softworks, Inc.
in January 2000. Softworks, Inc.'s products improve the management, performance
and integrity of critical corporate information across Windows NT, UNIX and
mainframe platforms and will be incorporated into the Company's software
portfolio.

During 1999, EMC completed construction of a state-of-the-art software
development lab in Hopkinton, Massachusetts to support the Company's growing
software research and development efforts. EMC believes that its investments in
software development will accelerate adoption of EMC Enterprise Storage Network
models and facilitate implementation of an E-Infostructure by customers.

Revenues from enterprise storage software represented approximately 12%, 8%
and 4% of revenues in 1999, 1998 and 1997, respectively.

ENTERPRISE STORAGE SERVICES

PROFESSIONAL SERVICES

EMC's Enterprise Storage Professional Services business, formed in 1997,
designs and delivers world-class professional services to its global customer
base. Such professional services assist customers in assessing, designing and
implementing storage solutions and an E-Infostructure customized to maximize
their return on information assets.

INTERNET SERVICES

EMC's Internet Services Group, formed in 1997, provides a comprehensive web
site management service, leveraging the Company's resources, including its
Symmetrix systems and its suite of enterprise storage software. Through this
service, the Company develops, implements, maintains and monitors all the
technical aspects of a customer's internet presence, including management of
internet-based electronic commerce and database applications as well as web and

EMC's Data General division, formed in 1999, designs, manufactures, markets
and supports the Company's line of AViiON open systems servers, which range from
dual-processor departmental servers to enterprise-wide systems. These servers,
combined with software and services, address market requirements for a
simplified computing environment that eliminates the complexity, reduces the
total cost of ownership, and provides reliability, high availability and
increased control of information.

EMC's Data General division also provides integrated, pre-packaged
solutions, function-specific servers and related services that provide customers
with the highest levels of information availability.

Revenue from EMC's Data General division server products represented
approximately 9%, 12% and 15% of revenues in 1999, 1998 and 1997, respectively.

CUSTOMER SERVICE

EMC's Customer Service organization, which includes over 3,000 technical,
field and support personnel, monitors the status of the Company's storage
solutions at customer sites 24 hours a day, seven days a week, 365 days a year.
These hardware and software solutions contain remote support features which
enable EMC customer service personnel to continuously monitor, diagnose and
resolve issues, wherever the product is located, often without the need for
on-site service. In 1999, the Company expanded its customer service capabilities
with the addition of new customer support centers in Japan and Australia.

MARKETS AND CHANNELS

STORAGE SYSTEMS MARKET

During 1999, the Company focused primarily on two major customer markets:
the Global 2000 and Internet businesses. These markets are characterized by
their requirements for large amounts of information storage capacity and the
advanced functionality provided by EMC's products.

4

GLOBAL 2000

The Global 2000, defined as the world's 2000 largest corporations, represent
a significant percentage of the Company's customer base. The Global 2000's
computing requirements encompass multiple computer platforms, including
mainframes, and those running the UNIX and Windows NT operating systems.

As the size and scope of those systems increases, the Company's Global 2000
customers are deploying EMC's Enterprise Storage Networks for the consolidation,
management, sharing and protection of the information generated by those
platforms. By building an E-Infostructure to support multiple business
applications, these customers are able to quickly, cost-effectively and reliably
deploy and expand applications and systems. The Company believes it is the
leading storage supplier to the Global 2000.

INTERNET BUSINESS

Internet-related businesses, those that conduct their primary business over
the Internet or provide Internet-related services to end users or other
businesses, represent a rapidly growing segment of the Company's customer base.
These businesses require rapid and constant access to extremely large volumes of
information. The Internet-related businesses' computing requirements are
typically standardized on a single computer platform, incorporating components
from several leading suppliers. EMC believes it is the leading storage provider
to Internet-related businesses.

In October 1999, the Company launched its EMC Proven E-Infostructure
program. The EMC Proven program provides Internet-based businesses and service
providers with a marketing vehicle to effectively communicate the inherent value
of their investments in information infrastructure to customers and investors.
EMC Proven members have implemented the necessary enterprise storage resources
to operate at peak efficiency, adapt to a constantly changing business climate
and easily manage Internet-driven growth.

MARKETING AND CUSTOMERS

EMC markets its products through multiple distribution channels, including
its direct sales force and selected distributors, systems integrators, resellers
and OEMs. The Company has a direct sales presence throughout North America,
Latin America, Europe, the Middle East, South Africa and the Asia Pacific region
and uses distributors as its primary distribution channel in other areas of the
world. During 1999, the Company continued broadening its direct and indirect
sales presence worldwide.

During 1999, the Company derived 63% of its revenue from North America; 3%
from Latin America; 27% from Europe, the Middle East and Africa; and 7% from the
Asia Pacific region.

INDIRECT CHANNELS

The Company believes its Symmetrix and CLARiiON products are well suited for
sale by resellers, systems integrators and OEMs. The Company has reseller or OEM
agreements with several systems vendors. These agreements enable the reseller or
OEM to market and resell certain of the Company's systems worldwide, subject to
certain terms and conditions, for connection to certain of the reseller or OEM's
respective computing platforms. The Company's principal reseller and OEM
agreements are with Unisys Corporation, Fujitsu/Siemens Computers ("FSC"),
International Business Machines Corporation ("IBM") (formerly Sequent Computer
Corporation), Selectron, a subsidiary of AT&T/ NCR Corporation, Compagnie des
Machines Bull S.A. and NEC Corporation ("NEC"). EMC also had a reseller
agreement with Hewlett-Packard Company for enterprise storage products until
June 30, 1999, at which time the parties agreed to terminate this contract.

5

ALLIANCES

The Company has alliances with leading software, relational database and
application companies, including Microsoft Corporation, SAP AG, Oracle
Corporation and other major independent software applications vendors. EMC
intends to continue to form additional strategic alliances. EMC's strategy is to
work closely with leading software companies to provide added value to its
customers by integrating EMC solutions with software applications that customers
rely on to manage their day-to-day business operations.

NEW BUSINESS DEVELOPMENT

The Company actively pursues new business development through a dedicated
organization focused on developing new businesses aligned to the Company's
markets. This is accomplished by maintaining a long-term view on the industry's
potential and continually assessing the market. Key objectives are to identify
and close significant business development opportunities (mergers, acquisitions
and investments) that are aligned with the Company's strategic direction,
including hardware, software and services businesses that complement and augment
those of the Company, and to manage, develop and integrate such new businesses
into EMC.

MANUFACTURING AND QUALITY

EMC's products are assembled and tested primarily at the Company's
facilities in Massachusetts, North Carolina and Cork, Ireland. Product
components manufactured by subcontractors in the United States and Europe are
assembled in accordance with production standards and quality controls
established by EMC. See "Properties."

The Company employs a corporate-wide Total Quality Management philosophy to
ensure the quality of its designs, manufacturing processes and suppliers. The
Company's manufacturing operations in Massachusetts currently hold an ISO 9001
Certificate of Registration. This internationally recognized endorsement of
ongoing quality management represents the highest level of certification
available. The Company's manufacturing operations in Ireland currently hold an
ISO 9002 Certificate of Registration and ISO 14001 Environmental Management
Standard Certification. In addition, EMC sites in the United Kingdom, Italy,
France, Australia, New Zealand and South Africa hold ISO certifications.

RAW MATERIALS

EMC's products utilize the Company's engineering designs, with industry
standard and semi-custom components and subsystems. Among the most important
components that EMC uses are disk drives, high density memory components and
power supplies. See "Factors that May Affect Future Results--If EMC's suppliers
do not meet its quality or delivery requirements, EMC could have decreased
revenues and earnings."

PATENTS

EMC has been granted or owns by assignment approximately 500 patents. The
Company also has a number of patent applications pending relating to its
hardware and software products.

BACKLOG

The Company manufactures its products on the basis of its forecast of
near-term demand and maintains inventory in advance of receipt of firm orders
from customers. Products are configured to customer specifications and are
generally shipped by the Company shortly after receipt of the order. Customers
may reschedule orders with little or no penalty. For these reasons, the
Company's backlog at any particular time is not meaningful because it is not
necessarily indicative of future sales levels.

6

COMPETITION

In the Global 2000 and Internet markets, EMC competes primarily with
computer systems manufacturers. In the Company's opinion, these companies
compete based on their overall market presence and their ability to sell both
computer systems and storage systems.

The Company believes that it has a number of competitive advantages over
these companies, including product, distribution and customer service. The
Company believes the advantages in its products include performance, capacity,
availability, connectivity, value-added software, time to market enhancements
and total value of ownership. The Company believes its advantages in
distribution include its direct sales force and its broad network of indirect
sales channels. The Company believes its advantages in customer service include
its ability to effectively monitor and provide service (which is often remote
and without interruption to a company's business) for its systems and software
24 hours a day, seven days a week, 365 days a year.

EMPLOYEES

As of January 31, 2000, EMC had approximately 17,700 employees worldwide.
None of the Company's domestic employees is represented by a labor union, and
the Company has never suffered an interruption of business as a result of a
labor dispute. The Company considers its relations with its employees to be
good.

FINANCIAL INFORMATION ABOUT SEGMENTS, FOREIGN AND DOMESTIC OPERATIONS AND EXPORT
SALES

The Company is active in three business segments: storage products; server
products; and services. Sales and marketing operations outside the United States
are conducted through sales subsidiaries and branches located principally in
Europe, Latin America and the Asia Pacific region. The Company has three primary
manufacturing facilities, one in Massachusetts, which provides Symmetrix
products to the North American markets, one in North Carolina, which
manufactures CLARiiON systems and AViiON servers, and one in Ireland which
manufactures Symmetrix systems and CLARiiON systems. Total exports, in millions,
from these facilities amounted to approximately $2,575, $2,184, and $1,884 in
1999, 1998 and 1997, respectively. (See Note P to the Company's Consolidated
Financial Statements.)

ITEM 2. PROPERTIES

The Company's principal corporate offices are located at 35 Parkwood Drive,
Hopkinton, Massachusetts. As of December 31, 1999, the Company owned or leased a
total of approximately 4.5 million square feet of space worldwide which is used
primarily for manufacturing, research and development, customer service, sales,
marketing and general administration.

The Company also owns and leases space for its sales and services offices
and for general administration worldwide, and owns land in the Hopkinton,
Massachusetts and Cork, Ireland areas for possible expansion purposes. The
Company believes its present level of manufacturing and other capacity, along
with its plans for expansion, will be sufficient to accommodate its
requirements.

ITEM 3. LEGAL PROCEEDINGS

The Company is a party to certain litigation which it considers routine and
incidental to its business. Management does not expect the results of any of
these actions to have a material adverse effect on the Company's business,
results of operations or financial condition.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matter was submitted to a vote of the Company's stockholders during the
fourth quarter of the fiscal year covered by this report.

REVENUES

Total revenues were $6,715.6, $5,436.2 and $4,487.9 in 1999, 1998 and 1997,
respectively, representing increases of $1,279.4, or 24%, from 1998 to 1999, and
$948.3 or 21% from 1997 to 1998.

Enterprise storage hardware revenues from products sold directly and through
OEMs and resellers were $4,006.5, $3,167.1 and $2,496.7 in 1999, 1998 and 1997,
respectively, representing increases of $839.4, or 27%, from 1998 to 1999 and
$670.4, or 27%, from 1997 to 1998. The increase in enterprise systems revenues
was primarily due to the continued strong demand for the Company's Symmetrix
series of products. These products address the growing demand for
enterprise-wide storage solutions, allowing users to move, store and protect
mission critical information in UNIX, Windows NT and mainframe environments.

12

Enterprise storage software revenues from products sold directly and through
OEMs and resellers were $821.7, $445.4 and $176.9 in 1999, 1998 and 1997,
respectively, representing increases of $376.3, or 85%, from 1998 to 1999 and
$268.5, or 152%, from 1997 to 1998. The increase in software revenues was
primarily due to increased licenses of enterprise storage software on Symmetrix
systems, both newly shipped and already installed, and the successful
introduction of new and enhanced software products.

Revenues from enterprise switching products sold directly by McDATA,
primarily the ESCON director series of products, were $142.8, $178.8 and $189.1
in 1999, 1998 and 1997, respectively, representing a decrease of $36.0, or 20%,
from 1998 to 1999 and a decrease of $10.3, or 5%, from 1997 to 1998. The
decreases from 1998 to 1999 and from 1997 to 1998 were primarily due to the
product transition from ESCON-based to fibre-channel-based directors. The
Company anticipates that revenues from ESCON directors will continue to decline.

Revenues from the CLARiiON line of storage products, excluding related
service revenues, were $415.6, $413.9 and $499.4 in 1999, 1998 and 1997,
respectively, representing an increase of $1.7, or 0.4%, from 1998 to 1999 and a
decrease of $85.5, or 17%, from 1997 to 1998. The increase in 1999 CLARiiON
revenues reflects an increase in direct sales offset by decreased sales volume
from indirect channels. The decrease in 1998 is primarily the result of a longer
than anticipated product transition from SCSI-based to fibre-based storage
products, and the resultant decrease in sales volume from indirect channels.

Total storage products revenues were $5,386.7, $4,205.2 and $3,362.0 in
1999, 1998 and 1997, respectively, representing an increase of $1,181.5, or 28%,
from 1998 to 1999 and an increase of $843.2, or 25%, from 1997 to 1998. The
increase in both periods is due primarily to sales of enterprise storage
hardware and software.

Revenues from AViiON server products were $596.3, $655.6 and $660.6 in 1999,
1998 and 1997, respectively, representing decreases of $59.3, or 9%, from 1998
to 1999 and $5.0, or 1%, from 1997 to 1998. The decrease in revenue from 1998 to
1999 was primarily the result of the closing of certain international sales
offices in an effort to refocus the business and improve profitability.

Service revenues were $732.6, $575.3 and $465.3 in 1999, 1998 and 1997,
respectively representing an increase of $157.3, or 27%, from 1998 to 1999 and
an increase of $110.0, or 24%, from 1997 to 1998. The increase in both periods
was primarily a result of the growth in EMC professional services and the
acquisitions of the professional services businesses Groupe MCI and Millennia
III, Inc. in the second and third quarters of 1998, respectively. In addition,
service revenues continue to grow as a result of the larger installed base
driven by increased product unit sales.

Enterprise hardware and software revenues for 1999, 1998 and 1997 under the
Company's reseller agreement with Hewlett-Packard Company ("HP") were $217.1,
$718.0 and $504.1, respectively, representing 3%, 13% and 11% of total revenues,
respectively. The Company and HP agreed to terminate their reseller contract for
enterprise storage products effective as of June 30, 1999. The Company also has
a reseller agreement with HP for CLARiiON and AViiON products, which represented
2%, 3% and 6% of revenues in 1999, 1998 and 1997, respectively.

Revenues on sales into the North American markets were $4,257.1, $3,367.8
and $2,708.2 in 1999, 1998 and 1997, respectively, representing increases of
$889.3, or 26%, from 1998 to 1999, and $659.6, or 24%, from 1997 to 1998. The
revenue growth reflects continued strong demand for the Company's products and
services.

Revenues on sales into the markets of Europe, the Middle East and Africa
were $1,844.3, $1,597.6 and $1,323.2 in 1999, 1998 and 1997, respectively,
representing increases of $246.7, or 15%, from 1998 to 1999, and $274.4, or 21%,
from 1997 to 1998. The reduced growth rate in 1999 reflects the impact of
closing certain Data General sales offices.

13

Revenues on sales into the markets in the Asia Pacific region were $439.0,
$381.5 and $396.3 in 1999, 1998 and 1997, respectively, representing an increase
of $57.5, or 15%, from 1998 to 1999, and a decrease of $14.8, or 4%, from 1997
to 1998. The increase in 1999 was due to the Company's efforts to expand its
business in this region combined with strong demand for the Company's products
and services. The decrease in 1998 was principally attributable to a downturn in
economic trends in the Asia Pacific market.

Revenues on sales into the markets of Latin America were $175.2, $89.2 and
$60.2 in 1999, 1998 and 1997, respectively, representing increases of $86.0, or
96%, from 1998 to 1999 and $29.0, or 48%, from 1997 to 1998. The increase in
both periods was primarily due to the Company's efforts to expand its business
in this region combined with strong demand for the Company's products and
services.

GROSS MARGINS

Overall gross margins increased to 51.5% in 1999, compared to 44.9% in 1998
and 41.8% in 1997. Product gross margins increased to 54.0% in 1999, compared to
46.5% in 1998 and 42.4% in 1997. The increase in product margins for both
periods is primarily attributable to increased licensing of the Company's
enterprise software products, which have higher gross margins than sales of the
Company's hardware products. Software revenue as a percentage of total revenues
increased to 12% in 1999 from 8% in 1998 and 4% in 1997. Other factors affecting
product gross margins include the impact of component cost declines being
greater than the impact of product price declines. The Company currently
believes that product price declines will continue.

Service gross margins decreased to 30.8% in 1999, compared to 31.2% in 1998
and 36.5% in 1997. The decrease in service margins from 1998 to 1999 is
primarily due to a decrease in Data General service revenues caused by the
closure of certain international sales offices. The decrease in service margins
from 1997 to 1998 is primarily due to a significant investment in EMC
professional services during 1998.

RESEARCH AND DEVELOPMENT

Research and development ("R&D") expenses were $572.5, $435.3 and $332.1 in
1999, 1998 and 1997, respectively. As a percentage of revenues, R&D expenses
were 9%, 8% and 7% in 1999, 1998 and 1997, respectively. The increase in R&D
spending levels from 1997 to 1998 and 1998 to 1999 reflects the Company's
ongoing research and development efforts in a variety of areas, including EMC
ESN technologies, network attached storage products, enhancements to the
Symmetrix family of products, new enterprise storage software products and fibre
channel connectivity. R&D for 1998 also includes costs associated with the
integration of Conley Corporation, acquired in August 1998, which became the EMC
Cambridge Software Development Center.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative ("SG&A") expenses were $1,435.5,
$1,087.7 and $826.4 in 1999, 1998 and 1997, respectively. As a percentage of
revenues, SG&A expenses were 21%, 20% and 18% in 1999, 1998 and 1997,
respectively. The increase in spending levels for both periods is primarily due
to the Company's efforts to build an infrastructure to achieve broader coverage
and greater account depth around the world and to expand its technical sales
organization to support the current and expected growth in software revenues. In
addition, during 1999, the Company increased its direct sales presence where it
previously relied upon resellers.

14

RESTRUCTURING, MERGER AND OTHER CHARGES

During fiscal year 1999, the Company recorded a total charge of $223.6
related to restructuring, merger and other charges primarily related to the
acquisition of Data General. During 1998, the Company recorded charges totaling
$135.0 related to a restructuring program and other charges.

During the fourth quarter of 1999, the Company approved and implemented a
restructuring program in connection with its acquisition of Data General. The
restructuring plan, which is expected to be completed by December 2000, provides
for the consolidation of the Company's operations and elimination of duplicative
facilities worldwide. Accordingly, during 1999, the Company recorded a charge of
approximately $170.6 related to employee termination benefits, facility closure
costs, asset disposals and other exit costs which the Company has recorded in
operating expenses. The expected cash impact of the charge is approximately
$140.7 of which $52.4 was paid in 1999.

The restructuring program includes an aggregate net reduction of the
workforce by approximately 1,100 employees, approximately 59% of whom are or
were based in North America and 23% of whom are or were based in Europe. The
employee separations affect the majority of business functions and job classes.
Of the approximately 1,100 employees identified, approximately 500 were
terminated in 1999.

In 1999, the Company also recorded a charge for merger costs of $23.5 for
financial advisory services, legal, accounting and other direct expenses related
to the Data General acquisition which has been recorded in operating expenses.
In addition, the Company recorded a $14.1 charge related to asset impairments
recorded in operating expenses and recorded a charge of $15.4 for capitalized
software and inventory write-downs which is included in cost of product sales.

In 1998, the Company recorded a charge of $135.0 related to a restructuring
program and certain asset write-downs resulting from the program. The charge
included approximately $82.4 related to employee termination benefits, asset
write downs and other exit costs which the Company has recorded in operating
expenses and approximately $52.6 for capitalized software and inventory write
downs which are included in cost of product sales. The total cash impact of the
restructuring charge is approximately $58.5, of which $24.4 was paid in 1998 and
$21.6 was paid in 1999. As of December 31, 1999, the remaining accruals of $15.7
from the 1998 restructuring program are primarily related to excess vacant
rental properties in Europe.

The 1998 restructuring program included an aggregate net reduction of the
workforce by approximately 480 employees, approximately 65% of whom were based
in North America and the remainder of whom were based in Europe and the Asia
Pacific region. The employee separations affected the majority of business
functions and job classes. Of the 480 employees identified, approximately 400
were terminated during 1998 and 80 were terminated in 1999.

INVESTMENT INCOME AND INTEREST EXPENSE

Investment income increased to $131.9 in 1999, from $114.4 in 1998 and $82.6
in 1997. Investment income was earned primarily from investments in cash
equivalents and short and long-term investments. Investment income increased in
1999 and 1998 primarily due to higher average cash and investment balances which
were derived from operations.

Interest expense decreased to $33.5 in 1999 from $34.8 in 1998. Interest
expense increased to $34.8 in 1998 from $31.3 in 1997. The decrease in 1999 from
1998 is primarily due to conversions of the 3 1/4% Convertible Subordinated
Notes due 2002 of the Company (the "3 1/4% Notes") to Common Stock. The increase
in 1998 from 1997 was primarily due to the issuance of the 3 1/4% Notes and the
6% Convertible Subordinated Notes due 2004 of the Company (the "6% Notes").

OTHER INCOME/(EXPENSE), NET

The net other income was $17.7 in 1999 compared with the net other income of
$0.4 in 1998 and $1.1 in 1997. The increase in the net other income from 1998 to
1999 is primarily attributable to gains on the sale of publicly traded
securities acquired as part of the Data General acquisition.

PROVISION FOR INCOME TAXES

The provision for income taxes was $346.6 in 1999, $260.3 in 1998 and $181.8
in 1997, which resulted in effective tax rates of 25.5%, 28.5% and 23.6% in
1999, 1998 and 1997, respectively. The effective tax rates in 1999, 1998, and
1997 were lower than the statutory federal rate (35%) due primarily to the
realization of the benefits of the Company's global tax strategies and the
benefits derived from its offshore manufacturing operations. The major impact of
the Data General acquisition to the tax provision under the pooling of interest
method of acquisition accounting was a reduction in the valuation reserve
formerly recorded for certain Data General net operating loss carryforwards and
the non-deductibility of certain restructuring charges. The Company anticipates
that the effective tax rate for fiscal 2000 will be approximately 27%.

FINANCIAL CONDITION

Cash and cash equivalents and short and long-term investments were $3,173.7
and $2,380.3 at December 31, 1999 and 1998, respectively, an increase of $793.4.
In 1999, cash and cash equivalents

16

increased by $273.9 and short and long-term investments increased by $519.5.
This reflects the Company's continued efforts to invest excess cash in short and
long-term investments, which generate a higher yield than cash and cash
equivalents.

Cash provided by operating activities was $1,371.6. This was primarily
generated from net income offset by an increase in working capital, primarily
attributable to an increase in accounts receivable, consistent with the growth
of the business. Cash used by investing activities was $1,170.9, principally for
purchases of investments and additions to property, plant and equipment.

Cash provided by financing activities was $73.2, principally from the
issuance of Common Stock from stock option exercises.

The Company has available for use a credit line of $50.0 and may elect to
borrow at any time. In March 1997, the Company sold $517.5 of the 3 1/4% Notes.
The 3 1/4% Notes are generally convertible into shares of Common Stock at any
time prior to the redemption date at a conversion price of $11.33 per share. As
of December 31, 1999, $57.1 of the 3 1/4% Notes have been converted into Common
Stock. On February 15, 2000, the Company announced that it would redeem all of
the outstanding 3 1/4% Notes on March 15, 2000; however, the Company believes
that substantially all of the outstanding 3 1/4% Notes were converted into
Common Stock on or prior to such date. In May 1997, the Company sold $212.8 of
the 6% Notes. The 6% Notes are generally convertible into shares of common stock
at a conversion price of $83.82 per share, subject to adjustment in certain
events. As of December 31, 1999, none of the 6% Notes have been converted into
Common Stock. Based on its current operating and capital expenditure forecasts,
the Company believes that the combination of funds currently available, funds
generated from operations and its available line of credit will be adequate to
finance its ongoing operations.

To date, inflation has not had a material impact on the Company's financial
results.

17

FACTORS THAT MAY AFFECT FUTURE RESULTS

The Company's prospects are subject to certain uncertainties and risks. This
Annual Report on Form 10-K also contains certain forward-looking statements
within the meaning of the Federal Securities Laws. The Company's future results
may differ materially from its current results and actual results could differ
materially from those projected in the forward-looking statements as a result of
certain risk factors, including but not limited to those set forth below, other
one-time events and other important factors disclosed previously and from time
to time in EMC's other filings with the Securities and Exchange Commission.

IF EMC'S SUPPLIERS DO NOT MEET ITS QUALITY OR DELIVERY REQUIREMENTS, EMC COULD
HAVE DECREASED REVENUES AND EARNINGS.

EMC purchases several sophisticated components and products from one or a
limited number of qualified suppliers, including some of its competitors. These
components and products include disk drives, high density memory components and
power supplies. EMC has experienced delivery delays from time to time because of
high industry demand or the inability of some vendors to consistently meet its
quality and delivery requirements. If any of its suppliers were to fail to meet
the quality or delivery requirements needed to satisfy customer orders for its
products, EMC could lose time-sensitive customer orders and have significantly
decreased quarterly revenues and earnings, which would have a material adverse
effect on EMC's business, results of operations or financial condition.

Additionally, EMC periodically transitions its product line to incorporate
new technologies. The importance of transitioning its customers smoothly to new
technologies, along with its historically uneven pattern of quarterly sales,
intensifies the risk that a supplier who fails to meet its delivery or quality
requirements will have an adverse impact on EMC's revenues and earnings.

EMC MAY BE UNABLE TO KEEP PACE WITH RAPID INDUSTRY CHANGES.

The computer storage and server markets are characterized by rapid
technological change, frequent new product introductions and evolving industry
standards. Sales of the Symmetrix series of products constitute the principal
source of revenues for EMC and EMC expects these sales to continue to be the
principal source of its revenues in the near future. Customer preferences in
these markets are difficult to predict, however, and there can be no assurance
that the Symmetrix series or other of the Company's products will continue to be
properly positioned in the market or to receive customer acceptance. In
addition, as a significant number of EMC's products are designed to be fully
compatible with the computers and operating systems of IBM and others, EMC's
business could also be adversely affected by modifications in the design or
configuration of these computers and operating systems.

Risks inherent in the transition to new products include the difficulty in
forecasting customer demand accurately, the inability to expand production
capacity to meet demand for new products, the impact of customers' demand for
new products on the products being replaced and delays in initial shipments of
new products. Further risks inherent in new product introductions include the
uncertainty of price-performance relative to products of competitors,
competitors' responses to the introductions and the desire by customers to
evaluate new products for longer periods of time. There can be no assurance that
EMC will be able to effectively manage the transitions to new products or new
technologies.

THE MARKETS EMC SERVES ARE HIGHLY COMPETITIVE, AND EMC MAY BE UNABLE TO COMPETE
EFFECTIVELY.

EMC competes with many established companies in the computer storage and
server industries and certain of these companies have substantially greater
financial, marketing and technological resources, larger distribution
capabilities, earlier access to customers and more opportunity to address

18

customers' various information technology requirements than EMC. EMC's business
may be adversely affected by the announcement or introduction of new products by
its competitors, including hardware, software and services, price reductions of
its competitors' equipment or services and the implementation of effective
marketing strategies by its competitors.

COMPETITIVE PRICING COULD ADVERSELY AFFECT EMC'S REVENUES AND EARNINGS.

Competitive pricing pressures exist in the computer storage and server
markets and have had and may in the future have an adverse effect on EMC's
revenues and earnings. There also has been and may continue to be a willingness
on the part of certain competitors to reduce prices in order to preserve or gain
market share, which EMC cannot foresee. EMC currently believes that pricing
pressures are likely to continue.

To date, EMC has been able to manage its component and product design costs.
However, there can be no assurance that EMC will be able to continue to achieve
reductions in component and product design costs. The relative and varying rates
of product price and component cost declines could have an adverse effect on
EMC's earnings.

CHANGES IN FOREIGN LAWS, RULES OR REGULATIONS OR OTHER CONDITIONS COULD IMPAIR
EMC'S INTERNATIONAL SALES.

A substantial portion of EMC's revenues is derived from sales outside the
United States. In addition, a substantial portion of EMC's products is
manufactured outside of the United States. Accordingly, EMC's future results
could be adversely affected by a variety of factors, including changes in
foreign currency exchange rates, changes in a specific country's or region's
political or economic conditions, trade restrictions, import or export licensing
requirements, the overlap of different tax structures or changes in
international tax laws, changes in regulatory requirements, compliance with a
variety of foreign laws and regulations and longer payment cycles in certain
countries.

RISKS ASSOCIATED WITH EMC'S INDIRECT CHANNELS OF DISTRIBUTION MAY ADVERSELY
AFFECT EMC'S FINANCIAL RESULTS.

EMC derives a significant percentage of its product revenues from indirect
channels of distribution, including resellers, systems integrators and
distributors. EMC's financial results could be adversely affected if its
contracts with its indirect channels of distribution were terminated, if EMC's
relationship with its indirect channels were to deteriorate or if the financial
condition of its indirect channels were to weaken. In addition, as EMC's
business grows, EMC may have an increased reliance on indirect channels of
distribution. There can be no assurance that EMC will be successful in
maintaining or expanding these channels. If EMC is not successful, EMC may lose
certain sales opportunities. Furthermore, the partial reliance on indirect
channels of distribution may materially reduce the visibility to management of
potential orders, thereby making it more difficult to accurately forecast such
orders. In addition, there can be no assurance that indirect channels will not
develop or market products in competition with EMC in the future.

HISTORICALLY UNEVEN SALES PATTERNS COULD SIGNIFICANTLY IMPACT QUARTERLY REVENUES
AND EARNINGS.

EMC's quarterly sales have historically reflected an uneven pattern in which
a disproportionate percentage of a quarter's total sales occur in the last month
and weeks and days of each quarter. This pattern makes prediction of revenues,
earnings and working capital for each financial period especially difficult and
uncertain and increases the risk of unanticipated variations in quarterly
results and financial condition. EMC believes this uneven sales pattern is a
result of many factors including:

19

- the significant size of EMC's average product price in relation to its
customers' budgets, resulting in long lead times for customers' budgetary
approval, which tends to be given late in a quarter

- the tendency of customers to wait until late in a quarter to commit to
purchase in the hope of obtaining more favorable pricing from one or more
competitors seeking their business

- the fourth quarter influence of customers spending their remaining capital
budget authorization prior to new budget constraints in the first quarter
of the following year

- seasonal influences

EMC's uneven sales pattern also makes it extremely difficult to predict
near-term demand and adjust manufacturing capacity accordingly. If orders vary
substantially from the predicted demand, the ability to assemble, test and ship
orders received in the last weeks and days of each quarter may be limited, which
could adversely affect quarterly revenues and earnings.

In addition, EMC's revenues in any quarter are substantially dependent on
orders booked and shipped in that quarter, and its backlog at any particular
time is not necessarily indicative of future sales levels. This is because:

- EMC manufactures its products on the basis of its forecast of near-term
demand and maintains inventory in advance of receipt of firm orders from
customers

- EMC generally ships products shortly after receipt of the order

- customers may reschedule orders with little or no penalty

Moreover, delays in product shipping, caused by loss of power or
telecommunications or similar services, or an unexpected decline in revenues
without a corresponding and timely slowdown in expenses, could intensify the
impact of these factors on EMC's business, results of operations and financial
condition.

EMC MAY HAVE DIFFICULTY SUSTAINING AND MANAGING ITS GROWTH.

EMC has a history of rapid growth. EMC's future operating results will
depend on its management's ability to manage growth, including, but not limited
to, hiring and retaining significant numbers of qualified employees, forecasting
revenues, controlling expenses and managing its manufacturing capacity and other
assets and executing on its plans. An unexpected decline in the growth rate of
revenues without a corresponding and timely reduction in expense growth or a
failure to manage other aspects of growth could have a material adverse effect
on EMC's business, results of operations or financial condition.

In addition, EMC's growth requires enhancement and expansion of its
infrastructure, including its management team, information systems and
manufacturing operations. The Company's continued success and profitability
depends on its ability to continue to improve its infrastructure to keep pace
with the growth in its overall business.

EMC'S BUSINESS MAY SUFFER IF IT IS UNABLE TO ATTRACT AND RETAIN KEY PERSONNEL.

EMC's continued growth and success depends to a significant extent on the
continued service of senior management and other key employees, the development
of additional management personnel and the hiring of new qualified employees.
Competition for highly skilled personnel is intense in the high technology
industry. There can be no assurance that EMC will be successful in continuously
recruiting new personnel or in retaining existing personnel. The loss of one or
more key or other employees or EMC's inability to attract additional qualified
employees or retain other employees could have a material adverse effect on
EMC's business, results of operations or financial condition.

20

MANUFACTURING RISKS COULD DIRECTLY IMPAIR EMC'S FINANCIAL RESULTS.

EMC's products operate near the limits of electronic and physical
performance and are designed and manufactured with relatively small tolerances.
If flaws in design, production, assembly or testing were to occur by EMC or its
suppliers, EMC could experience a rate of failure in its products that would
result in substantial repair or replacement costs and potential damage to EMC's
reputation. Continued improvement in manufacturing capabilities and control of
material and manufacturing quality and costs are critical factors in the future
growth of EMC. EMC frequently revises and updates manufacturing and test
processes to address engineering and component changes to its products and
evaluates the reallocation of manufacturing resources among its facilities.
There can be no assurance that EMC's efforts to monitor, develop and implement
appropriate test and manufacturing processes for its products will be sufficient
to permit EMC to avoid a rate of failure in its products that results in
substantial delays in shipment, significant repair or replacement costs and
potential damage to EMC's reputation, any of which could have a material adverse
effect on EMC's business, results of operations or financial condition.

EMC'S BUSINESS COULD BE MATERIALLY ADVERSELY AFFECTED AS A RESULT OF THE RISKS
ASSOCIATED WITH ACQUISITIONS AND INVESTMENTS.

As part of its business strategy, EMC seeks to acquire businesses that offer
complementary products, services or technologies. These acquisitions are
accompanied by the risks commonly encountered in an acquisition of a business
including, among other things:

- the effect of the acquisition on EMC's financial and strategic position
and reputation

- the failure of an acquired business to further EMC's strategies

- the difficulty of integrating the acquired business

- the lack of experience in new markets, products or technologies

- the diversion of EMC's management's attention from other business concerns

- the impairment of relationships with customers of the acquired business

- the potential loss of key employees of the acquired company

- the implementation and maintenance of uniform company-wide standards,
procedures and policies

- the potential incompatibility of business cultures

These factors could have a material adverse effect on EMC's business,
results of operations or financial condition. EMC expects that the consideration
paid for future acquisitions, if any, could be in the form of cash, stock,
rights to purchase stock or a combination of these. To the extent that EMC
issues shares of stock or other rights to purchase stock in connection with any
future acquisition, existing stockholders will experience dilution and
potentially decreased earnings per share.

EMC also seeks to invest in businesses that offer complementary products,
services or technologies. These investments are accompanied by risks similar to
those encountered in an acquisition of a business.

EMC'S BUSINESS COULD BE MATERIALLY ADVERSELY AFFECTED AS A RESULT OF THE RISKS
ASSOCIATED WITH ALLIANCES.

EMC has alliances with leading software, relational database and enterprise
application companies, and EMC plans to continue its strategy of developing key
alliances. EMC works with these companies to integrate its products with their
software applications. There can be no assurance that EMC will be

21

successful in its ongoing strategic alliances or that EMC will be able to find
further suitable business relationships as it develops new products. Any failure
to continue or expand such relationships could have a material adverse effect on
EMC's business, results of operations or financial condition.

There can be no assurance that companies with which EMC has strategic
alliances, certain of which have substantially greater financial, marketing and
technological resources than EMC, will not develop or market products in
competition with EMC in the future, discontinue their alliances with EMC or form
alliances with EMC's competitors.

EMC'S BUSINESS MAY SUFFER IF IT CANNOT PROTECT ITS INTELLECTUAL PROPERTY.

EMC generally relies upon patent, copyright, trademark and trade secret laws
and contract rights in the United States and in other countries to establish and
maintain EMC's proprietary rights in its technology and products. However, there
can be no assurance that any of EMC's proprietary rights will not be challenged,
invalidated or circumvented. In addition, the laws of certain countries do not
protect EMC's proprietary rights to the same extent as do the laws of the United
States. Therefore, there can be no assurance that EMC will be able to adequately
protect its proprietary technology against unauthorized third-party copying or
use, which could adversely affect EMC's competitive position. Further, there can
be no assurance that EMC will be able to obtain licenses to any technology that
it may require to conduct its business or that, if obtainable, such technology
can be licensed at a reasonable cost.

From time to time, EMC receives notices from third parties claiming
infringement by EMC's products of third-party patent or other intellectual
property rights. Responding to any such claim, regardless of its merit, could be
time-consuming, result in costly litigation, divert management's attention and
resources and cause EMC to incur significant expenses. In the event there is a
temporary or permanent injunction entered prohibiting EMC from marketing or
selling certain of its products or a successful claim of infringement against
EMC requiring EMC to pay royalties to a third party, and EMC fails to develop or
license a substitute technology, EMC's business, results of operations or
financial condition could be materially adversely affected.

YEAR 2000 PROBLEMS MAY DISRUPT EMC'S BUSINESS.

The information provided below constitutes a "Year 2000 Readiness
Disclosure" under the Year 2000 Information and Readiness Disclosure Act.

In February 1997, EMC established a Year 2000 program to address systems and
software problems in interpreting certain dates in calendar year 2000. Under
this program, EMC completed, prior to January 1, 2000, an assessment of the
hardware and software in its business information systems and completed the
necessary modifications. To date, EMC has not experienced, and is not aware of,
any Year 2000 problems or disruptions in its internal systems; however, EMC
cannot, at this time, be assured that any such problems or disruptions, if they
were to occur, would not have a material impact on EMC's business, results of
operations or financial condition.

Under its Year 2000 program, EMC sought and has received certifications of
Year 2000 compliance from all of its key vendors and suppliers. EMC has also
received certifications or statements of Year 2000 compliance from other vendors
and suppliers and has assessed questionnaire responses and related information
from other third parties. To date, EMC has not received any notification from
any of its key vendors, suppliers or other third parties of any Year 2000
problems or disruptions; however, EMC cannot, at this time, be assured that Year
2000 problems of third parties will not have a material impact on EMC's
business, results of operations or financial condition.

EMC has designed and tested the current versions of its Symmetrix series of
products and the current versions of its other products to be Year 2000
compliant. EMC has made upgrades available for

22

the older versions of its Symmetrix series of products and for certain other of
its older products that have not been tested for Year 2000 compliance so that
such products will test as Year 2000 compliant. EMC's CLARiiON storage products
and AViiON servers test as Year 2000 ready or EMC has made upgrades available to
make such products test as Year 2000 ready. There can be no assurance that Year
2000 problems in EMC's products, if they were to occur, would not have a
material impact on EMC's business, results of operations or financial condition.

The assessment, remediation, testing and contingency planning phases of
EMC's Year 2000 program are complete. The total cost of such program has not
had, and EMC does not anticipate that the total cost of such program will have,
a material effect on its business, results of operations or financial condition.

The most reasonably likely worst case scenarios regarding failures to
interpret certain dates in calendar Year 2000 would include a hardware failure,
the corruption or loss of data contained in EMC's internal information systems,
a failure affecting EMC's key vendors, suppliers or customers, the failure of
infrastructure services provided by government agencies or other third parties,
and customer dissatisfaction related to the performance of EMC's products.

Under its program, EMC developed a Year 2000 contingency plan. This
contingency plan includes, among other things, manual "work-arounds" for
hardware and software failures, as well as substitution of systems, if required.

Further information about EMC's Year 2000 readiness is available at the
Company's website at HTTP://WWW.EMC.COM/YEAR2000.

LITIGATION THAT EMC MAY BECOME INVOLVED IN MAY ADVERSELY AFFECT EMC.

In the ordinary course of business, EMC may become involved in litigation,
administrative proceedings and governmental proceedings. Such matters can be
time-consuming, divert management's attention and resources and cause EMC to
incur significant expenses. Furthermore, there can be no assurance that the
results of any of these actions will not have a material adverse effect on its
business, results of operations or financial condition.

CHANGES IN REGULATIONS COULD ADVERSELY AFFECT EMC.

EMC's business, results of operations and financial condition could be
adversely affected if laws, regulations or standards relating to EMC or its
products were newly implemented or changed.

EMC'S STOCK PRICE IS VOLATILE.

EMC's stock price, like that of other technology companies, is subject to
significant volatility because of factors such as:

- the announcement of new products, services or technological innovations by
EMC or its competitors

- quarterly variations in its operating results

- changes in revenue or earnings estimates by the investment community

- speculation in the press or investment community

In addition, EMC's stock price may be affected by general market conditions
and domestic and international economic factors unrelated to EMC's performance.
Because of these factors, recent trends should not be considered reliable
indicators of future stock prices or financial results.

23

ITEM 7A: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK

The Company is exposed to market risk, primarily from changes in interest
rates, foreign exchange rates and credit risk. To manage the volatility relating
to these exposures, the Company enters into various derivative transactions
pursuant to the Company's policies to hedge against known or forecasted market
exposures.

FOREIGN EXCHANGE RISK MANAGEMENT

As a multinational corporation, the Company is exposed to changes in foreign
exchange rates. These exposures may change over time and could have a material
adverse impact on our financial results. Historically, the Company's primary
exposures related to sales denominated in the Euro, the Japanese yen and the
British pound. Additionally, the Company's exposure to emerging market
economies, particularly in Latin America and South East Asia, has recently
increased because of its expanding presence in these markets. Despite the
relative size of the Company's exposures in these markets, the inherent
volatility of these economies could negatively impact the Company's financial
results.

The Company uses foreign currency forward and option contracts to manage the
risk of exchange rate fluctuations. In all cases, the Company uses these
derivative instruments to reduce its foreign exchange risk by essentially
creating offsetting market exposures. The instruments held by the Company are
not leveraged and are not held for trading or speculative purposes.

The Company uses forward exchange contracts to hedge its net asset position
and uses a combination of option and forward contracts to hedge anticipated cash
flows. The hedging activity is intended to offset the impact of currency
fluctuations on assets, liabilities and cash flows denominated in foreign
currencies. The success of the hedging program depends on forecasts of
transaction activity in the various currencies. To the extent that these
forecasts are overstated or understated during periods of currency volatility,
the Company could experience unanticipated currency gains or losses.

The Company employs a variance/covariance model to calculate value-at-risk
for its combined foreign exchange position. This model assumes that the
relationships among market rates and prices that have been observed over the
last year are valid for estimating risk over the next trading day. Estimates of
volatility and correlations of market factors are drawn from the RiskMetrics
dataset as of December 31, 1999. This model measures the potential loss in fair
value that could arise from changes in market conditions, using a 95% confidence
level and assuming a one-day holding period. The value-at-risk on the combined
foreign exchange position was $0.4 million as of December 31, 1999.

INTEREST RATE RISK

The Company maintains an investment portfolio consisting of debt securities
of various issuers, types and maturities. The investments are classified as
available for sale and all are denominated in U.S. dollars. These securities are
recorded on the balance sheet at market value, with any unrealized gain or loss
recorded in other comprehensive income/(loss). These instruments are not
leveraged, and are not held for trading purposes. A portion of the Company's
investment portfolio is comprised of mortgage-backed securities which are
subject to prepayment risk.

The Company employs a variance/covariance model to calculate value-at-risk
for its combined investment portfolios. This model assumes that the
relationships among market rates and prices that have been observed over the
last year are valid for estimating risk over the next trading day. Estimates of
volatility and correlations of market factors are drawn from the RiskMetrics
dataset as of December 31, 1999. This model measures the potential loss in fair
value that could arise from changes

24

in market conditions, using a 95% confidence level and assuming a one day
holding period. The value at risk on the investment portfolios was $2.2 million
as of December 31, 1999.

CREDIT RISK

Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of temporary cash investments,
short and long-term investments and trade and notes receivable. The Company
places its temporary cash investments and short and long-term investments in
investment grade instruments and limits the amount of investment with any one
financial institution. The credit risk associated with trade receivables is
minimal due to the large number of customers and their broad dispersion over
many different industries and geographic areas.
