PART I
ITEM 1. BUSINESS

3Com Corporation was founded on June 4, 1979 and pioneered the networking
industry. Over the years, 3Com and its subsidiaries ("3Com" or "the Company")
have evolved from a supplier of discrete networking products to a broad-based
supplier of local area network (LAN) and wide area network (WAN) systems. With
an emphasis on connectivity from the edge to the core of the network, 3Com
offers customers a broad range of networking solutions that include switches,
hubs, remote access systems, routers, network management software, network
interface cards (NICs), modems and handheld connected organizers. 3Com has
structured its business, products, marketing and sales to address four key
customer markets: large enterprise - typically with more than 500 users,
including the corporate, education, retail, health care and government sectors;
small/medium enterprise - those organizations with 25-500 users; consumer/small
office, home office (SOHO); and carrier/service provider - including traditional
telecommunication providers, competitive local exchange carriers and Internet
service providers.

3Com's name is derived from its focus on computer communication compatibility.
Since its inception, the Company has been a leader in defining, shaping and
promoting the growth of networking infrastructures that transmit information
across the enterprise or the Internet quickly and reliably. Currently, the
networking industry is undergoing a profound shift of emphasis from parallel
networks - separate data, voice and video infrastructures running side by side -
to converged networks that integrate all communications onto a single network
infrastructure. The Company intends to be the leading provider of converged
networking technologies and solutions. A key element of the Company's strategy
is to make networks faster, more intelligent, and fundamentally easier to
design, install, maintain and upgrade.

Since 1992, 3Com has augmented its internal growth by actively pursuing a course
of strategic acquisitions to expand its distribution capabilities, technologies
and product offerings. From fiscal years 1993 through 1997, the Company acquired
several companies to further its technological growth and market position,
primarily in enterprise networking. Of particular note, the acquisitions of
Synernetics, Inc., NiceCom, Ltd., Chipcom Corporation, AXON Networks, Inc. and
OnStream Networks, Inc. enhanced 3Com's product offerings in LAN and WAN
Asynchronous Transfer Mode (ATM), Fiber Distributed Data Interface (FDDI) and
Ethernet switching, enterprise remote access and remote network management and
monitoring (RMON2).
1

In the first quarter of fiscal 1998, the Company merged with U.S. Robotics
Corporation (U.S. Robotics), the leading supplier of products and systems for
accessing information across the wide area network, including modems and remote
access products. The merger was accounted for as a pooling-of-interests and was
valued at approximately $6.6 billion on the date the acquisition was announced.
The two companies' complementary capabilities and leadership position in their
respective areas has created a single networking company with the ability to
deliver integrated end-to-end LAN and WAN solutions to the broadest set of
customers in the industry.

In the fourth quarter of fiscal 1998, the Company acquired Lanworks
Technologies, Inc., a leading provider of PC network boot technologies and
products. PC network boot technologies are critical for remote desktop
management, which includes activities such as automated configuration of PCs
upon start-up. This acquisition was valued at $13.0 million and was accounted
for as a purchase.

The Company's acquisition strategy is consistent with the current trend of
consolidation in the networking industry. Such consolidation is expected to
continue.

During fiscal 1998 the Company announced a joint development agreement with
Siemens AG's (Siemens) Public Communications Networks Group to produce a
multi-service central office switch for carriers and service providers, as well
as the industry's first stackable voice/data networking solutions for enterprise
environments. In addition, each company will resell certain of the other
company's products. In 1998, the Company also entered into a strategic agreement
with Newbridge Networks Corporation (Newbridge) to develop and deploy
next-generation, end-to-end networks supporting converged voice, video and data
applications that employ standards-based techniques for network traffic
prioritization and policy control. The agreement with Newbridge provides 3Com
with industry-leading ATM WAN switching capabilities. In addition, 3Com's Palm
Computing(R) business unit established strategic relationships with IBM to
manufacture the WorkPad PC companion and with QUALCOMM to develop wireless
communications products that are compatible with the Palm Computing platform.

3Com's products are primarily distributed and serviced worldwide through 3Com
and systems integrators, value-added resellers (VARs), national resellers and
dealers, distributors and OEMs. Certain products, such as analog and digital
modems, NICs, handheld connected organizers, hubs, low-end switches, and the
Network Starter Kit, are also sold through electronics catalogs and retailers.
The Company also has a direct sales organization focused on large enterprise and
carrier/service provider customers worldwide.

The Company's objective is to maintain a leading market share position in the
product areas in which it competes. In fiscal 1998 the Company maintained or
extended its leadership as the number one global provider of NICs, modems,
workgroup switches, remote access concentrators, hubs and handheld connected
organizers, according to various industry sources.

In fiscal 1998 the Company announced and/or introduced a number of new products
and enhancements to refresh its traditional product lines as well as a

SYSTEMS PRODUCTS

LAN Switching Platforms: In the large enterprise environment where the network
connects hundreds or thousands of users, 3Com switches provide cost-effective,
high-speed links between multiple network segments, simplifying network design
and reducing network latency in client/server networks. Switches can also
provide direct links to either the desktop or server, providing dedicated
capacity to high-bandwidth users. In small/medium-sized enterprises, switches
provide additional bandwidth to help businesses leverage information to maximize
productivity and support growth.

The Company incorporates internally developed application specific integrated
circuits (ASICs) into its switches as a central component of its switching
product strategy and believes this enables it to dramatically improve the
performance and reliability of its switches while reducing costs. 3Com switches
are available in either chassis (one box) or stackable (i.e. additional capacity
added with additional boxes) form factors and support the industry's migration
to higher speed switching technologies.

3Com offers a variety of switches tailored to suit the requirements of any
organization. The Company's OfficeConnect Ethernet/Fast Ethernet switches
combine simplicity of design, installation and operation with advanced
functionality and outstanding speed at a low cost. The Company's award-winning
SuperStack II switches include multiple products, each with appropriate port,
media and connectivity specifications to meet the needs of the network at the
workgroup, data center or backbone level.

To meet the requirements of the large enterprise LAN network backbone for
high-density connectivity, scalable capacity, reliability and network control,
the Company offers High-Function switches in its CoreBuilder product line.
CoreBuilder switches include the CoreBuilder 3500 Layer 3 switch, the
CoreBuilder 5000 multi-technology switching platform, CoreBuilder 2500 and 6000
Ethernet to FDDI, Fast Ethernet and ATM backbone switch, CoreBuilder 7000 and
7000HD ATM switches, and the flagship CoreBuilder 9000 high-bandwidth
aggregation switch.

WAN Switching Platform: For the large enterprise, carrier or service provider,
building or extending current networks to carry voice, video and data, the
Company's PathBuilder (formerly AccessBuilder(R) 9000) line of WAN switches
provides ATM multi-services integration.

Hub Platforms: Hubs act as concentrators of network traffic generated from the
desktop and define specific network segments, relaying the traffic either within
the workgroup or onto the network backbone. Unlike switches, each desktop
connected through a hub shares the total available bandwidth of the hub with
other users. Their relatively low cost per port, manageability and ease-of-use
make hubs a popular choice for workgroup connectivity in any enterprise
environment. Multiple hubs are frequently connected to a switch, which acts as a
"hub of a hub," to segment the network and improve overall performance.

The Company designs, manufactures and markets a full range of hubs for customers
of all sizes. For the small office or branch office, OfficeConnect Ethernet and
Fast Ethernet hubs offer simple, plug and play connectivity. The Company's
SuperStack II hubs offer a range of options for small, medium and large
enterprises, including: entry-level unmanaged hubs for small and medium-sized
offices; and flexible, mixed Ethernet, Fast Ethernet, and Token Ring workgroup
hubs and Gigabit Ethernet workgroup hubs for small to large-sized LANs.

Routers: Routers are protocol-dependent devices that connect sub-networks
together. 3Com offers a variety of backbone and remote office routers that
facilitate enterprise internetworking. For remote offices, SuperStack II
NETBuilder and OfficeConnect NETBuilder routers provide scalable, multi-protocol
links to remote branch offices of any size. For companies deploying extranets,
3Com has recently begun offering product bundles, which include the SuperStack
II NETBuilder routers and bridges and the OfficeConnect NETBuilder routers;
these bundles facilitate the deployment of VPNs. VPNs support large-scale access
for suppliers, partners, customers and branch offices at a substantial cost
savings over traditional WAN access charges.

4

Remote Access Platforms: Remote access products bring the benefits of the
network to remote users, including telecommuters, Internet and on-line users,
corporate suppliers, and a host of other users that access the network from a
distance. The Company's remote access products leverage 3Com's HiPer Digital
Signaling Processing (DSP) technology, a multi-function digital signal
processing engine that integrates sophisticated functionality on a single chip.
HiPer DSP enables the Company's remote access platforms to achieve
industry-leading port densities, (particularly critical in space constrained
carrier environments). HiPer DSP also provides the ability to reprogram the
Company's remote access systems to support new applications - including
encryption, video compression, LAN telephony and Voice over IP - without costly
hardware upgrades. 3Com's remote access offerings include three product lines
for carrier-class and enterprise remote access.

The SuperStack II Remote Access 3000 and 1500 product lines offer
high-performance remote access support for mid-sized enterprises or service
providers with multiple numbers of smaller points of presence (POPs). The
stackable format provides scalable, economical remote access connectivity with
full functionality. The SuperStack II remote access products are also
hot-swappable (i.e. the ability to add or exchange modules without taking the
system out of service) and incorporate multiple system-resiliency features.

The AccessBuilder 7000 Access Concentrator is a chassis-based, high-density
platform for service providers with large dial-up networks and for enterprises
building large-scale corporate intranets. It supports high-bandwidth links to
Ethernet LANs and offers hot-swappable modules and a robust fault-tolerant
architecture.

The Total Control Remote Access Concentrator is a very high-density platform for
carriers and large enterprises that offers channelized bandwidth supporting all
major analog and digital dial up techniques in a single chassis. Designed for
applications where network downtime must be minimized and remote user
performance maximized, the Total Control system offers hot-swappable modules,
dual redundant power supplies, standby modems, and a host of other reliability
features. Uses of Total Control range from providing central site or POP access
to networks for Internet service providers, on-line information services,
interexchange carriers and corporations, to transaction processing applications
such as credit card verification.

CLIENT ACCESS PRODUCTS

3Com's Client Access Products include NICs and modems. In both categories, 3Com
is the worldwide market leader according to various industry sources.

NICs: Network interface cards, also known as adapters, are add-in printed
circuit boards that allow network servers, personal computers, laptop computers
and workstations to connect to the LAN. 3Com NICs provide complete solutions for
a full range of network applications and environments. 3Com offers NICs for
Ethernet, Fast Ethernet, Gigabit Ethernet, Token Ring, FDDI and ATM
connectivity. Many NICs are available with combined connectivity to support the
networking industry's migration from Ethernet to Fast Ethernet for increased
bandwidth.

All 3Com NICs feature patented Parallel Tasking(R) architecture, which improves
network performance, and DynamicAccess(TM) software, which provides the NIC with
intelligence to help optimize overall network performance, management and
control.

Modems: Modems provide dial-up access to the Internet, enterprise LANs and a
host of communications services including fax. 3Com provides modems for desktop
and mobile users. The Company was first to market with modems that are compliant
with the ITU V.90 standard for 56 Kbps download capabilities. The V.90 standard
applies to pulse code modulation technology permitting downloading of data over
regular analog telephone lines at speeds up to 56 Kbps per second and requires
compatible phone lines and modems at server sites. All V.90 products are capable
of 56 Kbps downloads; however, due to Federal Communications Commission (FCC)
regulations, current download speeds are limited to 53 Kbps. Actual speeds may
vary. The Company also provides software to facilitate upgrade to new
technologies and capabilities and is designed to be easy to install and easy to
use. They have received numerous awards for reliable connectivity and high
performance. 3Com's modem products are designed based upon the Company's
proprietary data pump architecture and offer reliable connections in compliance
with virtually all official and most proprietary data communications standards.
Desktop modem products include the U.S. Robotics(R), Courier(TM) and
3ComImpact(R) brands.

Today, portable laptop and notebook computers have the processing power, storage
and displays that make them the primary computer for many users. For these
devices, 3Com offers smaller form-factor PC cards, which are available in
configurations for LAN access (NICs), WAN access (modems) and combined LAN+WAN
access (NIC and modem), as well as for wireless and ISDN connectivity. 3Com's
portable LAN and WAN PC card products are sold under the 3Com Megahertz(R)
brand.

HANDHELD CONNECTED ORGANIZERS

3Com's handheld connected organizers are a new category of computing: handheld
devices designed to work as companion products to desktop and laptop computers,
allowing information management both remotely and on the desktop. Individuals
may utilize the organizers to track a variety of information from appointments
and phone numbers to more specialized data, such as patient records or
construction specifications. In the enterprise setting, the organizers can be
used to enhance productivity, for example by providing mobile retrieval of key
data from corporate business applications such as finance, manufacturing or
sales automation systems. In addition, with add-on components such as a wireless
modem, these devices can be used by both consumer and enterprise users to access
information on the Internet.

The organizers include a docking cradle, which is connected to the user's mobile
or desktop computer, providing automatic back-up and seamless synchronization of
information between the handheld device and the larger computer, thus ensuring
that both systems have the most current information. The products also include
character recognition software that allows users to add and edit information
with a stylus, while away from the desktop.

The Company's market-leading handheld connected organizers include the PalmPilot
and Palm III models. Both the PalmPilot and the Palm III products are based upon
the Palm Computing operating system, which is supported by over 7,500
independent software developers producing a variety of applications, utilities
and games for the organizer products.

PRODUCT DEVELOPMENT

The Company develops its products in a manner consistent with its goal to make
networking pervasive by providing solutions that combine high performance with
ease of use. The Company's research and development expenditures were $581.6
million, $502.5 million and $337.8 million in fiscal years 1998, 1997 and 1996,
respectively.

3Com's ownership of core networking technologies creates opportunities to
leverage its engineering investments and develop more integrated products for
simpler, more powerful and more innovative networking solutions for customers in
each of its target markets: large enterprise, small/medium enterprise,
consumer/SOHO, and carrier/service provider. The Company plans to invest in
emerging technologies for use in existing and future products, as well as to
improve and enhance existing products to extend their useful lives, reduce
manufacturing costs and increase functionality.

The Company has a strong history of incorporating ASICs into its products to
provide key functions and the capacity for future upgrades. Customers are
thereby able to realize the benefits of new technologies and enhanced
capabilities through inexpensive, simple software upgrades rather than
expensive, disruptive hardware replacement. In addition, ASICs facilitate higher
density platforms - critical in certain applications, such as high-speed Layer 3
switching - and are less costly to manufacture. The Company incorporates ASIC
technology into many of its products, including NICs, switches, hubs, routers
and remote access equipment.

In addition to the development of custom ASICs to improve performance, increase
reliability and reduce costs, the Company is investing in the following key
areas: network management; Fast Ethernet, Gigabit Ethernet, ATM, Layer 3
switching and other high-speed networking technologies; virtual local area
network (VLAN) capabilities; convergence solutions such as Voice over IP and LAN
telephony; WAN access, ISDN and other remote-access technologies; enhanced
connectivity in major operating environments, including Windows and Windows NT;
and remote access for single and mobile users (including data-over-cable and
Asymmetric Digital Subscriber Line (ADSL) technologies).

The Company's modem and remote access products are designed using software
programs that run on digital signal processors and microprocessors. These
designs allow for rapid modification or addition of product features through
simple software downloads. As a result, the Company believes it is
well-positioned to exploit advances in technology and pass the benefits on to
customers quickly, introducing new features and improving performance faster and
at a lower cost than many of its competitors.

MARKETS AND CUSTOMERS

3Com's customers range from individual consumers of personal electronics to
large global corporations, and encompass companies in a wide variety of
industries, including finance, health care, manufacturing, telecommunications,
government, education, and retail. The Company's merger with U.S. Robotics gave
3Com a broader reach and more leverage across its four target markets: large
enterprise, small/medium enterprise, consumer/SOHO, and carrier/service
provider.

The Company's strong channel presence enables customers to gain access to 3Com
solutions through their supplier of choice. The Company's unparalleled retail
and reseller distribution channels provide ready access to the wide array of
3Com products and solutions on a worldwide basis. 3Com also works directly with
end users to establish long-term customer relationships.

Around the world, 3Com serves its customers through a variety of sales channels
including direct and indirect channels. Indirect channels include systems
integrators, VARs, distributors, national dealers and resellers, OEMs and retail
stores. 3Com nurtures these relationships with incentive and training programs
that have earned special recognition from the industry. The Company's
multi-channel sales strategy encourages broad market coverage by allowing 3Com
sales personnel to create demand for the Company's products while giving
customers the flexibility to choose the most appropriate delivery channels. As
of and for the year ended May 31, 1998, the Company had one customer which
accounted for 14 percent of total sales and 14 percent of total accounts
receivable. The same customer accounted for 13 percent and 12 percent of total
sales for the fiscal years ended May 31, 1997 and 1996, respectively.

International Operations: 3Com distinguishes itself from many of its competitors
with its dedicated research and development, manufacturing, sales and service
organizations outside the United States. During fiscal 1998, the Company
increased off-shore manufacturing capacity by opening a new plant in Singapore
and installing additional manufacturing lines in its Ireland facility. The
Company maintains approximately 190 sales offices in 48 countries. The Company
markets its products internationally primarily through subsidiaries, sales
offices and relationships with OEMs and distributors with local presence in
Europe, Canada, Asia Pacific and Latin America (see Note 15 of the Notes to
Consolidated Financial Statements).

Customer Service: Since global networking infrastructures are becoming
increasingly complex, customers require vendors to help them manage and support
their networks as well as design and build them. Additionally, as customers'
networking purchases transition from point-product to connectivity systems, a
more solutions-oriented approach to service and support is required. The Company
recognized these trends early and has invested in a comprehensive worldwide
service and support organization capable of providing 7-by-24 customer support.
3Com customer services include design, installation and maintenance on-site, by
phone, or across the Internet. The Company also offers web-based
customer-specific support. Additionally, the Company provides a wide variety of
training services, including on-site training and computer-based courses that
allow customers to learn networking technologies at their own pace. The Company
supports its customers internationally from more than 140 different locations,
including eight technical call centers communicating with customers in more than
15 languages.

BACKLOG

3Com manufactures its products based upon its forecast of worldwide customer
demand and builds finished products in advance of receiving firm orders from its
customers. Orders are generally placed by the customer on an as-needed basis and
products are usually shipped within one to four weeks after receipt of an order.
Such orders generally may be canceled or rescheduled by the customer without
significant penalty. Accordingly, the Company does not maintain a substantial
backlog, and backlog as of any particular date is not indicative of 3Com's
future sales.

MANUFACTURING

3Com has manufacturing facilities in Santa Clara, California; Mount Prospect and
Morton Grove, Illinois; Boxborough and Southborough, Massachusetts; Salt Lake
City, Utah; Blanchardstown, Ireland; and Changi, Republic of Singapore. The
Singapore manufacturing facility began operations in fiscal 1998 and is 3Com's
first production site in the Asia Pacific region. The plant is the first in
Singapore to manufacture networking equipment and will produce 3Com's full range
of high-volume products from NICs and modems to sophisticated enterprise
systems. Purchasing, mechanical assembly, burn-in, testing, final assembly, and
quality assurance functions are performed at all of these facilities. The
Company also procures certain products and subassemblies through subcontractors.

Over the past several years, the Company has been investing in automating its
manufacturing capabilities, decreasing the costs and increasing the quality of
both manufacturing design and production. In fiscal 1997, the Company commenced
construction of an additional 170,000 square feet of office, manufacturing, and
research and development space in Ireland, and commenced construction of the
first phase of development of the new manufacturing facility in Singapore. Both
facilities were completed and occupied during fiscal 1998. In fiscal 1998, the
Company commenced construction of a 525,000 square foot research and development
and manufacturing facility in Marlborough, Massachusetts, which will replace
several existing facilities, and is expected to be occupied in the fourth
quarter of fiscal 1999. The Company also began consolidation of two
manufacturing plants in the Chicago area into one facility.

COMPETITION

Networking is a fast-paced market within the information systems industry
encompassing both LAN and WAN technologies that enable communications and access
to information over data and voice network infrastructures. The Company
participates primarily in designing, manufacturing and marketing both LAN/WAN
products and systems. The evolution of high-speed network technologies including
Fast Ethernet, Gigabit Ethernet, ATM, xDSL, cable and Layer 3 switching has
changed the competitive landscape and resulted in shorter product life cycles,
as well as the creation of new standards and competitors. 3Com's competitors
typically compete in one or more segments of the LAN/WAN sector of the
networking market. These companies are using their resources and technical
expertise to improve and expand their product lines in an effort to gain market
share. Several competitors are extending their product offerings beyond a single
market segment and are pursuing strategies more closely resembling 3Com's global
networking strategy. The industry continues to witness a wave of merger and
strategic partnering activity as companies seek to provide broader networking
solutions.

Large Enterprise Market: Competition in the large enterprise market is centered
primarily around three areas: network interface, LAN systems and high-speed,
broadband networking.

The market for NICs is highly competitive, with companies offering products that
support a range of Ethernet, Fast Ethernet, Token Ring, ATM and FDDI media.
Traditional competitors in the NIC market include Intel, IBM, Standard
Microsystems and Xircom. However, as the trend from Ethernet to Fast Ethernet to
Gigabit Ethernet accelerates, the competitive landscape is changing to favor
companies that have a strong position in these faster technologies, namely 3Com
and Intel.

The LAN systems market is characterized by a few broad-based suppliers offering
multiple product lines. This has been achieved through mergers and acquisitions,
through joint marketing agreements, and through internally developed products.
This industry consolidation, and the convergence of hub, switching and routing
technologies on single platforms, will likely continue, thus intensifying
competition, as reflected by the emergence of new entrants including Lucent
Technologies and Northern Telecom. Principal competitors in the network systems
large enterprise market include Bay Networks, Cabletron and Cisco Systems.

The market for high-speed, broadband networking products has grown rapidly,
driven by companies' implementations of bandwidth-intensive applications. As the
need for high-speed wide-area communications continues to grow, many carriers
and enterprises are looking to vendors to provide a new generation of equipment
which permits increases in performance both in terms of speed and number of
connections supported by the network. Other companies, including Ascend
Communications, Cisco Systems and Lucent Technologies have network access
switching products that are competitive with 3Com.

8

Small/Medium Enterprise Market: Competition in the small/medium enterprise
market is characterized by a large number of suppliers, ranging from small firms
with a limited number of products to very large firms from other industries with
only a few networking product offerings. The market for small/medium-sized
organizations encompasses products ranging from NICs to workgroup hubs to
high-density switches. Principal competitors of the Company in the small/medium
enterprise market include Bay Networks, Cisco Systems, Dlink, Hewlett-Packard
and Intel.

Consumer/SOHO Market: The consumer/SOHO market is characterized by a large
number of suppliers and a dependence on brand awareness. Products sold into the
consumer and SOHO areas include modems, entry-level hubs and switches and
handheld connected organizers.

The Company's primary competitors with respect to desktop modems include Boca
Research, Hayes Microcomputer Products and Zoom. The Company was the first to
begin commercial volume shipments of V.90 standard 56 Kbps technology products
in February 1998. 3Com anticipates vigorous competition from many of the
significant modem and remote access equipment manufacturers, most of which have
begun shipment of, or announced their intentions to, bring products featuring
the V.90 56 Kbps technology to market. The majority of these manufacturers have
implemented or intend to implement this high-speed technology with chipsets
provided by Lucent Technologies or Rockwell International.

In the emerging high-speed modem markets, the Company's primary competitors
include: Alcatel/Hayes, Cisco Systems, Efficient, and Flowpoint for xDSL modems,
and Bay Networks, General Instruments, Motorola, RCA, and Sony for cable modems.

Handheld connected organizers are an emerging product area. The Company's
competitors in this arena include Casio, Hewlett-Packard, Phillips, Psion and
Sharp. During fiscal 1998, Microsoft Corporation entered the handheld connected
organizer market as a licensor of the Windows CE operating system.

Carrier/Service Provider Market: The carrier/service provider market is
characterized by intense competition to sell remote access concentrators that
handle both digital and analog signals for POP connectivity. 3Com competes
against various manufacturers of integrated remote access concentrators,
including Ascend Communications, Bay Networks, Cisco Systems and Lucent
Technologies.

The carrier/service provider market is also characterized by competition to sell
head-end equipment for emerging high-speed xDSL and cable technologies. The
Company's competitors for xDSL head-end equipment include: Alcatel, Cisco
Systems, Fujitsu/Orkit, Lucent Technologies and Northern Telecom. For cable
head-end equipment, competitors include: Bay Networks, Cisco Systems, Com21 and
Motorola.

INTELLECTUAL PROPERTY AND RELATED MATTERS

The Company relies on U.S. and foreign patents, copyrights, trademarks and trade
secrets to establish and maintain proprietary rights in its technology and
products. 3Com has an active program to file applications for and obtain patents
in the U.S. and in selected foreign countries where a potential market for the
Company's products exists. The Company's general policy has been to seek patent
protection for those inventions and improvements likely to be incorporated in
its products or otherwise expected to be of value. 3Com has been issued 147 U.S.
patents (including 141 utility patents and 6 design patents) and has been issued
39 foreign patents. Numerous patent applications are currently pending in the
U.S. and other countries which relate to the Company's research and development.

There can be no assurance that any of these patents would be upheld as valid if
litigated. While the Company believes that its patents and patent applications
have value, it also believes that its competitive position depends primarily on
the innovative skills, technological expertise and management abilities of its
employees.

3Com has registered 92 trademarks in the United States and has registered 64
trademarks in one or more of 75 foreign countries. Numerous applications for
registration of domestic and foreign trademarks are currently pending.

EMPLOYEES

As of May 31, 1998, 3Com had approximately 12,920 full-time employees, of whom
3,165 were employed in engineering, 3,980 in sales, marketing and customer
service, 3,575 in manufacturing and 2,200 in finance and administration. None of
3Com's employees is represented by a labor organization, and the Company
considers its employee relations to be satisfactory.

ITEM 2. PROPERTIES

The Company operates in a number of locations worldwide. In fiscal 1998, the
Company entered into a number of property transactions, as follows:

During the first quarter of fiscal 1998, the Company signed a lease, which
replaced a previous land lease, for 300,000 square feet of office and research
and development space and a data center to be built on land adjacent to the
Company's headquarters site in Santa Clara, California. The lease expires in
August 2002, with an option to extend the lease term for two successive periods
of five years each. The Company has an option to purchase the property for $83.6
million, or at the end of the lease arrange for the sale of the property to a
third party with the Company retaining an obligation to the owner for the
difference between the sale price and $83.6 million, subject to certain
provisions of the lease. Construction of the buildings began in July 1997, and
the Company anticipates that it will occupy the facility and begin lease
payments in the second quarter of fiscal 1999.

During the first quarter of fiscal 1998, the Company signed a lease, which
replaced a previous land lease, for 525,000 square feet of office, research and
development and manufacturing space to be built on land in Marlborough,
Massachusetts for the consolidation and expansion of existing operations. The
lease expires in August 2002, with an option to extend the lease term for two
successive periods of five years each. The Company has an option to purchase the
property for $86.0 million, or at the end of the lease arrange for the sale of
the property to a third party with the Company retaining an obligation to the
owner for the difference between the sale price and $86.0 million, subject to
certain provisions of the lease. Construction of the buildings began in the
first quarter of fiscal 1998, and the Company anticipates that it will occupy
the facility and begin lease payments in the fourth quarter of fiscal 1999.
Adjacent to this property is a leased facility consisting of 100,000 square feet
of office space. This lease expires in December 1999.

During the fourth quarter of fiscal 1998, the Company notified the lessor of a
58-acre parcel of land near its existing headquarters in Santa Clara of its
intention to exercise its option to purchase the land for $49.5 million. On
March 26, 1998 the option was exercised, and the Company immediately sold a
portion of the land to a third party. Terms of the transaction resulted in the
Company reporting a net gain of $15.8 million on the sale of the property during
the fourth quarter of fiscal 1998. An additional gain of $4.2 million was
deferred pending the resolution of certain contingencies. The Company retained a
25-acre parcel of land for future development. This parcel of land is adjacent
to a 14-acre parcel of land previously purchased by the Company.

During the fourth quarter of fiscal 1998, the Company paid $38.3 million to
purchase property in Rolling Meadows, Illinois, which was previously under an
operating lease. The property consists of 40 acres of land and an existing
400,000 square foot facility. 3Com is expanding the building to a total of
510,000 square feet and will use the new facility to consolidate existing
operations in the Chicago area. Construction of this facility is expected to be
completed in the first quarter of fiscal 1999.

ITEM 3. LEGAL PROCEEDINGS

The Company is a party to lawsuits in the normal course of its business. The
Company believes that it has meritorious defenses in all lawsuits in which the
Company or its subsidiaries is a defendant. The Company notes that (i)
litigation in general and intellectual property and securities litigation in
particular can be expensive and disruptive to normal business operations and
(ii) the results of complex legal proceedings can be very difficult to predict
with any certainty.

Securities Litigation

On March 24 and May 5, 1997, putative securities class action lawsuits,
captioned Hirsch v. 3Com Corporation, et al., Civil Action No. CV764977
(Hirsch), and Kravitz v. 3Com Corporation, et al., Civil Action No. CV765962
(Kravitz), respectively, were filed against the Company and certain of its
officers and directors in the California Superior Court, Santa Clara County. The
complaints allege violations of Sections 25400 and 25500 of the California
Corporations Code and seek unspecified damages on behalf of a purported class of
purchasers of 3Com common stock during the period from September 24, 1996
through February 10, 1997. The actions are in discovery. No trial date has been
set.
11

On February 10, 1998, a putative securities class action, captioned Euredjian v.
3Com Corporation, et al., Civil Action No. C-98-00508CRB (Euredjian), was filed
against 3Com and several of its present and former officers and directors in
United States District Court for the Northern District of California asserting
the same class period and factual allegations as the Hirsch and Kravitz actions.
The complaint alleges violations of the federal securities laws, specifically
Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and seeks
unspecified damages. The Company has not responded to the complaint. The Hirsch,
Kravitz and Euredjian actions were filed after Intel Corporation sharply
decreased prices on its Fast Ethernet network interface cards, which resulted in
3Com decreasing its prices on similar products. The Company believes it has
meritorious defenses to the claims in the Hirsch, Kravitz and Euredjian actions
and intends to contest the lawsuits vigorously. An unfavorable resolution of the
actions could have a material adverse effect on the business, results of
operations or financial condition of the Company.

Several securities actions have been filed against the Company and certain of
its current and former officers and directors following the Company's merger
with U.S. Robotics. In December 1997, a putative securities class action,
captioned Reiver v. 3Com Corporation, et al., Civil Action No. C-97-21083JW
(Reiver), was filed in the United States District Court for the Northern
District of California. The complaint alleges violations of the federal
securities laws, specifically Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934, and seeks unspecified damages on behalf of a purported
class of purchasers of 3Com common stock during the period from May 19, 1997
through November 6, 1997. In December 1997 and January 1998, seven similar
shareholder class action lawsuits were filed in the United States District Court
for the Northern District of Illinois and the United States District Court for
the Northern District of California. The cases filed in the Northern District of
Illinois have been transferred to the Northern District of California, and the
cases have been consolidated in the Reiver action. A consolidated amended
complaint will be filed shortly.

On April 3, 1998, a complaint, captioned Florida State Board of Administration
and Teachers Retirement System of Louisiana v. 3Com Corporation, et al., Civil
Action No. C-98-1355 (Florida State Board), was filed in the United States
District Court for the Northern District of California. The complaint alleges
violations of the federal securities laws, violations of the Florida securities
laws, common law fraud and negligent misrepresentation based on factual
allegations similar to those asserted in the Reiver action. The Company has not
responded to the complaint. The Company believes it has meritorious defenses to
the claims in the Reiver and Florida State Board actions and intends to contest
the lawsuits vigorously. An unfavorable resolution of the actions could have a
material adverse effect on the business, results of operations or financial
condition of the Company.

In January 1998, two purported shareholder complaints relating to the Company's
June 1997 merger with U.S. Robotics, captioned Stanley Grossman v. 3Com
Corporation, et al., Civil Action No. CV771335, and Jason v. 3Com Corporation,
et al., Civil Action No. CV771713, were filed in California Superior Court,
Santa Clara County. The actions allege that 3Com, several of its officers and
directors, and several former U.S. Robotics officers violated Sections 11 and 15
of the Securities Act of 1933 by making alleged misrepresentations and omissions
in a May 8, 1997 registration statement. The complaints seek damages in an
unspecified amount on behalf of a purported class of persons who received the
Company's stock during the merger pursuant to the registration statement. The
Company has not responded to the complaints. The Company has filed a motion in
Delaware Chancery Court seeking an injunction preventing plaintiffs from
proceeding, on the basis that plaintiffs' claims are barred by a settlement in a
prior action. The Company believes it has meritorious defenses to the claims and
intends to contest the lawsuits vigorously. An unfavorable resolution of the
actions could have a material adverse effect on the business, results of
operations or financial condition of the Company.

In February 1998, a shareholder derivative action purportedly on behalf of the
Company, captioned, Wasserman v. Benhamou, et al., Civil Action No. 16200-NC,
was filed in Delaware Chancery Court. The complaint alleges that the Company's
directors breached their fiduciary duties to the Company by engaging in alleged
wrongful conduct from mid-1996 through November 1997, including the conduct
complained of in the securities litigation described above. The Company is named
solely as a nominal defendant, against whom the plaintiff seeks no recovery. The
Company and the individual defendants have filed a motion to dismiss the
complaint.

Intellectual Property Litigation

On April 28, 1997, Xerox Corporation filed suit against U.S. Robotics
Corporation and U.S. Robotics Access Corp. in the United States District Court
for the Western District of New York. The case is now entitled: Xerox
Corporation v. U.S. Robotics Corporation, U.S. Robotics Access Corp., Palm
Computing, Inc. and 3Com Corporation, Civil Action No. 97-CV-6182T. The
complaint alleges willful infringement of a United States patent relating to
computerized interpretation of handwriting. The complaint further prays for
unspecified damages and injunctive relief. Xerox has asserted that "Graffiti"
software and certain products of Palm Computing, Inc. infringe the patent. The
Company believes it has meritorious defenses to the claims and is contesting the
lawsuit vigorously. An unfavorable resolution of the action could have a
material adverse effect on the business, results of operations or financial
condition of the Company.

By an agreement effective February 27, 1998, the Company and Motorola, Inc.
settled the patent lawsuit pending between Motorola, Inc. and U.S. Robotics
Corporation, U.S. Robotics Access Corp. and U.S. Robotics Mobile Communications
Corp. in the United States District Court for the District of Massachusetts,
Civil Action No. 97-10339RCL. This case was dismissed on March 31, 1998. None of
the parties admitted fault. In connection with the settlement, the Company and
Motorola, Inc. entered into a cross-license of their respective patents relating
to high-speed analog modem technologies for implementation of international
standard data communication protocols. The terms of the settlement were not
material to the business, results of operations or financial condition of the
Company.

During February 1998 the Company and Livingston Enterprises, Inc. (Livingston)
agreed to settle the cases pending between Livingston and U.S. Robotics in the
United States District Court for the Northern District of California, Civil
Action Nos. C-97-3551CRB and C-97-3487CRB. These actions were dismissed on March
4, 1998. Neither party admitted fault in the settlement. The terms of the
settlement, which were not disclosed, were not material to the business, results
of operations, or financial condition of the Company.

Consumer Litigation

A putative consumer class action pending against the Company and U.S. Robotics
in the California Superior Court, Marin County, Bendall, et al. v. U.S. Robotics
Corporation, et al., Civil Action No. 170441 (Bendall), arising out of the
purchase of x2TM products and products upgradeable to x2, was coordinated with a
previously filed individual action in the California Superior Court, San
Francisco County, Intervention Inc. v. U.S. Robotics Corporation, Civil Action
No. 984352. Two putative consumer class action lawsuits pending against the
Company and U.S. Robotics in state court of Illinois arising out of the same
facts as those alleged in the California cases are stayed. Lippman, et al. v.
3Com, Civil Action No. 97 CH 09773, and Michaels, et al. v. U.S. Robotics Access
Corporation, et al., Civil Action No. 97 CH 14417. In June, 1998, the Company
filed a demurrer to the First Amended Complaint filed in Bendall. The Company
believes it has meritorious defenses to these lawsuits and intends to contest
the lawsuits vigorously. An unfavorable resolution of the actions could have a
material adverse effect on the business, results of operations or financial
condition of the Company.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

The following discussion should be read in conjunction with the Consolidated
Financial Statements and Notes thereto.

BUSINESS COMBINATIONS

For the year ended May 31, 1998. On June 12, 1997, 3Com Corporation completed
the merger with U.S. Robotics Corporation (U.S. Robotics), the leading supplier
of products and systems for accessing information across the wide area network
(WAN), including modems and remote access products. This merger was accounted
for as a pooling-of-interests. The Company issued approximately 158 million
shares of its common stock in exchange for all outstanding common stock of U.S.
Robotics. The Company also assumed all options to purchase U.S. Robotics' stock,
which were converted into options to purchase approximately 31 million shares of
the Company's common stock, pursuant to the terms of the merger.

All financial data of 3Com Corporation and its subsidiaries ("3Com" or "the
Company") presented in this Form 10-K have been restated to include the
historical financial information of U.S. Robotics in accordance with generally
accepted accounting principles and pursuant to Regulation S-X. The 3Com
statement of income for the fiscal year ended May 31, 1996 has been combined
with the U.S. Robotics statement of income for the fiscal year ended September
29, 1996. The 3Com statement of income for the fiscal year ended May 31, 1997
has been combined with the U.S. Robotics statement of income for the period from
July 1, 1996 through May 25, 1997. This combining methodology includes the last
three reported quarters of U.S. Robotics, ended September 29, 1996, December 29,
1996, and March 30, 1997, and the months of April and May 1997. To reflect a
complete 12-month year and a three-month fourth quarter and thereby enhance
comparability of periodic reported results, U.S. Robotics' results of operations
for the month ended March 30, 1997 are included in both the three-month period
ended March 30, 1997 and the three-month period ended May 25, 1997. This
presentation has the effect of including U.S. Robotics' results of operations
for the three-month period ended September 29, 1996 in both the combined years
ended May 31, 1997 and 1996, and reflects sales of $611.4 million and net income
of $13.5 million. The aggregate of net income for the three-month period ended
September 29, 1996 of $13.5 million and the one-month period ended March 30,
1997 of $112.9 million has been reported as a decrease to the Company's fiscal
1997 retained earnings. 3Com's balance sheet as of May 31, 1997 was combined
with U.S. Robotics' balance sheet as of May 25, 1997. The combining periods are
as follows:

FISCAL 1996 FISCAL 1997 QUARTERLY PERIODS
----------- -----------------------------

YEAR ENDED Q1'97 Q2'97 Q3'97 Q4'97
---------- ----- ----- ----- -----
3Com May `96 Aug `96 Nov `96 Feb `97 May `97
U.S. Robotics Sept `96 Sept `96 Dec `96 Mar `97 May `97*

*Three-month period which includes March, April, and May.

The results of operations for the fiscal year ended May 31, 1998 contain the
combined results of both 3Com and U.S. Robotics for the entire 12 months.

During the fourth quarter of fiscal 1998, the Company purchased Lanworks
Technologies, Inc. (Lanworks), a leading provider of PC network boot
technologies and products, for approximately $13.0 million in cash.
Approximately $8.4 million of the total purchase price represented purchased
in-process technology that had not yet reached technological feasibility and had
no alternative future use. This amount was charged to the Company's operations
in the fourth quarter of fiscal 1998.

For the year ended May 31, 1997. To extend its leadership position in the
enterprise Asynchronous Transfer Mode (ATM) market, on October 31, 1996, the
Company acquired OnStream Networks, Inc. (OnStream), a provider of ATM and
broadband WAN and access products. The acquisition was accounted for as a
pooling-of-interests. In addition, to increase its market presence
internationally, U.S. Robotics acquired distributors in Korea, Japan, Australia,
and Sweden, for an aggregate purchase price of $13.4 million in cash, net of
cash acquired, and issuance of stock with a fair value of $0.1 million, all of
which were accounted for as purchases.

19

For the year ended May 31, 1996. To enhance its product offerings and accelerate
its time-to-market in new technologies, the Company acquired Chipcom Corporation
(Chipcom), a provider of computer networking multi-function platforms, including
hubs, switching, and network management products, Primary Access Corporation
(Primary Access), a provider of integrated network access systems, and AXON
Networks, Inc. (AXON), a developer and manufacturer of remote network management
and data network traffic management products. The acquisitions of Chipcom and
Primary Access were accounted for as poolings-of-interests. The acquisition of
AXON was a purchase transaction. In addition, U.S. Robotics acquired Amber Wave
Systems, Inc. (Amber Wave) in a pooling-of-interests transaction, a developer of
local area network (LAN) switching products, and acquired Scorpio
Communications, Ltd. (Scorpio) in a purchase transaction, a designer,
manufacturer and marketer of scalable, fully redundant, fault-tolerant ATM
switches that targeted workgroup LAN, corporate backbone and WAN access
environments.

The impact of merger-related charges on the Company's operating expenses, taxes
and net income are discussed below. See Notes 3 and 12 of Notes to Consolidated
Financial Statements for additional information on the above business
combinations.


SUPPLEMENTAL OPERATING INFORMATION FOR U.S. ROBOTICS

Following is supplemental information regarding U.S. Robotics' results of
operations for the three-month period ended May 25, 1997 (in thousands). Results
for these periods exclude reclassifications made to conform to the Company's
financial statement presentation.

-------- --------- ---------

Net income (loss) $112,927 $(160,304) $ (47,377)
======== ========= =========

U.S. Robotics' sales for the month ended March 30, 1997 (March 1997) were
approximately $541.7 million, reflecting strong market demand worldwide for
information access devices including the introduction and initial high volume
shipments of products incorporating x2TM technology (x2 products). x2 technology
increases the potential speed for downloading data from 28.8 or 33.6 Kilobits
per second (Kbps) for standard V.34 modems to 56 Kbps. Consistent with U.S.
Robotics' non-linear quarterly sales pattern, sales in the first two months of
the quarter were relatively low and in the third month of the quarter, which
March 1997 represents, were significantly higher.

Gross margin for March 1997 was approximately $279.4 million, or 51.6 percent of
sales. The overall gross margin reflected the initial high volume shipments of
x2 products, which generated higher gross margins due to U. S. Robotics'
temporary "first to market" advantage over competitors in the 56 Kbps modem
market. Also, to a lesser extent, the overall gross margin reflected higher
margins on the initial sales of newer generation handheld connected organizer
products introduced during the month.

20

Total operating expenses for March 1997 were approximately $97.5 million, or
18.0 percent of sales. Sales and marketing expenses reflected significant
spending related to the introduction of x2 products, other marketing programs
designed to generate continuing growth in sales and efforts to expand market
share, and continuing investments to increase the worldwide sales force with the
intent of increasing sales of network systems products. General and
administrative expenses and research and development expenses reflected
continuing investments in personnel and systems necessary to support U.S.
Robotics' expanded level of business activity and its commitment to new product
and technology development. As a percentage of sales, total operating expenses
for March 1997 were low due to the non-linear sales pattern described above.

Gross sales for the two months ended May 25, 1997 were approximately $200.3
million. Net sales after provisions, primarily for product returns of $143
million and price protection of $33 million, were approximately $15.3 million.
These results principally reflect the following factors: U.S. Robotics'
non-linear sales pattern, as described above; lower than anticipated sales out
of the channel, due in part to confusion about the new 56 Kbps technologies and
concerns regarding the absence of an industry standard for 56 Kbps modems;
efforts to reduce levels of channel inventory, including increased emphasis on
sales out of the channel via price reductions and other promotions; and product
returns from channel partners whose sales out had been lower than anticipated.

Returns during the two months ended May 25, 1997 totaled $82.3 million,
reflecting primarily desktop modems and remote access concentrators. The
majority of the desktop modem returns consisted of older generation products,
which were heavily impacted by the March 1997 introduction of U.S. Robotics' 56
Kbps modem with x2 technology. Returns of remote access concentrators were due
primarily to lower than anticipated sales out of the distribution channel. Based
on negotiations with individual customers, U.S. Robotics allowed returns during
this period in excess of customers' contractual rights due to the 56 Kbps
technology transition and the desire to reduce channel inventory. Returns during
this period exceeded the March 30, 1997 balance in the allowance for sales
returns of $48.9 million by $33.4 million.

The price protection provision of $33 million related primarily to price
reductions effective subsequent to March 30, 1997 for desktop modems and remote
access concentrator product lines.

Gross margin for this period was affected adversely by the provision for price
protection described above, a provision for potentially excess and obsolete
inventory of approximately $15.4 million, and unabsorbed manufacturing costs.

Operating expenses for the two months ended May 25, 1997 were approximately
$187.6 million. Sales and marketing expenses reflected significant spending
related to the introduction of x2 products and newer generation handheld
connected organizer products, other marketing programs designed to generate
continuing growth in sales and expand market share, and continuing investments
to increase the worldwide sales force with the intent of increasing sales of
network systems products. General and administrative expenses and research and
development expenses reflected continuing investments in personnel and systems
necessary to support U.S. Robotics' anticipated growth and its commitment to new
product and technology development. As a percentage of sales, total operating
expenses for the two months ended May 25, 1997 were high due to the non-linear
sales pattern described above.

Other expenses, net, for the two months ended May 25, 1997 were approximately
$6.2 million. Such expenses reflected higher interest expense due to increased
short-term borrowing. During these two months, U.S. Robotics increased its
short-term borrowings from approximately $61 million to approximately $135
million, comprised of $10 million under an existing $90 million short-term
borrowing arrangement and $125 million under an existing $300 million revolving
credit facility. Such borrowings were primarily necessary to fund ongoing
operating expenses, including costs associated with the launch of the new x2
technology, as well as capital expenditures. The Company repaid such short-term
borrowing shortly after the closing of the merger in June 1997 between 3Com and
U.S. Robotics, and the use of these borrowing arrangements is no longer expected
to be required.

The provision for income taxes for the two months ended May 25, 1997 was a net
benefit of approximately $82.6 million, resulting in an effective tax rate of
34.0 percent.

Comparison of fiscal years ended May 31, 1998 and 1997

SALES

Fiscal 1998 sales totaled $5.42 billion, a decline of three percent from fiscal
1997 sales of $5.61 billion. Sales of client access products (e.g., network
interface cards (NICs) and modems) in fiscal 1998 were $2.89 billion, a decrease
of eight percent from fiscal 1997 sales of $3.15 billion. Sales of client access
products represented 53 percent of total sales in fiscal 1998 compared to 56
percent in fiscal 1997. Sales of network systems products (e.g., switches,
routers, hubs, and remote access products) in fiscal 1998 were $2.53 billion, an
increase of three percent compared to fiscal 1997 sales of $2.46 billion. Sales
of network systems products represented 47 percent of total sales in fiscal
1998, compared to 44 percent a year ago. Sales in the U.S. represented 55
percent of total sales for fiscal 1998 and fiscal 1997. The Company experienced
a decline from fiscal 1997 in domestic and international sales of four and two
percent, respectively.

Fiscal 1998 sales were affected by the following factors:

Industry Growth Rates. Networking industry growth rates have slowed since the
beginning of calendar 1997. While the industry had grown at rates in excess of
30 percent in prior years, recent reports indicate that the networking industry
worldwide grew by less than 20 percent during 1997, and this pattern has
continued into 1998.

Channel Inventory. In the second quarter of fiscal 1998, the Company adopted a
new inventory business model, which generally calls for fewer weeks' supply of
inventory in the distribution channel. The Company transitioned to this model
during the second and third quarters of fiscal 1998. As a result, sales during
these periods were adversely affected.

22

Modems. Fiscal 1998 sales of modem products decreased compared to fiscal 1997.
In January 1998, the International Telecommunications Union (ITU) finally
determined the V.90 standard for 56 Kbps technology. The Company believes that
the previous lack of such a standard contributed to delays in customers'
purchasing decisions for higher-speed modems and remote access concentrators.
Although the Company began shipping V.90 standard modems late in the third
quarter of fiscal 1998, the Company believes these delays, as well as product
transitions, adversely affected sales. In addition, the delay in the V.90
standard caused aggressive pricing in older generation modem products, which in
connection with the channel inventory reduction mentioned above, contributed to
a year-over-year decrease in sales.

Pricing. The pricing environment has been very competitive, and although the
Company experienced significant year-over-year unit growth in key products such
as Fast Ethernet NICs and workgroup switches, these gains were partially offset
by declines in average selling prices. For example, in fiscal 1998, the Company
experienced price decreases between 15 and 39 percent compared to fiscal 1997 in
a number of product segments, including modems, workgroup switches, hubs and
remote access concentrators. While the trend of declining average selling prices
is expected to continue in future periods, the Company believes that price
erosion will be less than that experienced in fiscal 1998.

Remote Access Concentrators. Fiscal 1998 sales of remote access concentrators
decreased compared to fiscal 1997. Factors affecting this decrease included
aggressive price competition, including the introduction of new higher-density
products at prices similar to the older lower-density products. In addition,
sales of remote access concentrators were impacted by the channel inventory
reduction described above.

Asia Pacific Economic Turmoil. During fiscal 1998, sales in the Asia Pacific
region increased only four percent compared to fiscal 1997. Sales growth was 48
percent in fiscal 1997 compared to fiscal 1996. Historically, the Asia Pacific
region had been a high growth region for the networking industry and the
Company. During fiscal 1998, however, several Asian countries experienced a
weakening of their local currencies and turmoil in their financial markets and
institutions, which the Company believes adversely affected financial results
during fiscal 1998.

Handheld Connected Organizer and Switching Products. Fiscal 1998 sales of
handheld connected organizer products more than doubled compared to fiscal 1997
and achieved growth in market share, according to recent industry reports.
Growth rates and market share gains in the handheld connected organizer market
may not be sustainable in the face of increasing competition from new entrants
to the market. In addition, the Company's workgroup switching products
experienced significant unit volume growth and increased sales, despite
significant declines in average selling prices and the effect of the channel
inventory reduction, as described in the above paragraphs.

GROSS MARGIN

Gross margin as a percentage of sales was 45.4 percent in fiscal 1998, compared
to 47.9 percent in fiscal 1997. In addition to the factors mentioned above, the
Company's year-over-year gross margin decline was affected by several factors,
including product mix, increased price competition, and higher period costs. The
Company's product mix included higher sales of certain NICs and workgroup
switching products, as well as an increase in sales to original equipment
manufacturers (OEMs), which carry lower gross margins. The U.S. Robotics brand
modems with x2 technology were introduced in the third quarter of fiscal 1997
with significantly higher margins, reflecting first-to-market pricing. During
the past twelve months, increased product and price competition in this product
segment resulted in a decline in gross margin percent. Additionally, the Company
experienced aggressive pricing of remote access products, as described above,
which resulted in a decline in gross margin percent. Fixed manufacturing costs
and period costs were a higher percentage of sales, primarily as a result of the
decrease in sales in the second and third quarters of fiscal 1998, but also due
to excess manufacturing capacity. The Company is continuing to consolidate
manufacturing and distribution sites in fiscal 1999.

OPERATING EXPENSES

Operating expenses in fiscal 1998 were $2.36 billion, or 43.6 percent of sales,
compared to $1.89 billion, or 33.8 percent of sales in fiscal 1997. Operating
expenses as a percentage of sales were higher than historical levels, in part
due to the reduced level of sales for fiscal 1998, as discussed above. Excluding
a purchased in-process technology charge of $8.4 million and merger-related and
other charges of $253.7 million primarily associated with the U.S. Robotics
merger, operating expenses would have been $2.10 billion, or 38.7 percent of
sales for fiscal 1998. Excluding a purchased in-process technology charge of
$54.0 million associated with the acquisition of Scorpio and a merger-related
charge of $6.6 million associated with the acquisition of OnStream, operating
expenses would have been $1.83 billion, or 32.7 percent of sales for fiscal
1997.
23

Sales and marketing expenses in fiscal 1998 increased $165.9 million or 15
percent from fiscal 1997. Sales and marketing expenses as a percentage of sales
increased to 23.0 percent of sales in fiscal 1998 from 19.3 percent in fiscal
1997. The year-over-year increase is attributable to the expansion of field
sales and marketing activities worldwide, primarily internationally, and
increased spending for the Company's customer service programs. In addition,
spending on the Company's global branding campaign during fiscal 1998
contributed to increased marketing expenses from the prior year.

Research and development expenses in fiscal 1998 increased $79.1 million or 16
percent compared to fiscal 1997. Research and development expenses as a
percentage of sales increased to 10.7 percent of sales compared to 9.0 percent
of sales in fiscal 1997. The year-over-year increase in research and development
expenses in absolute dollars and dollars as a percentage of sales was primarily
attributable to the cost of developing the Company's new products in the areas
of client access and switching, and its expansion into new technologies and
markets, such as xDSL. For example, during fiscal 1998, the Company developed a
fully-integrated (single-chip) Fast Ethernet NIC, the CoreBuilderTM Layer 3
Switch, the Palm IIITM handheld connected organizer, as well as many other key
new products. The Company believes the timely introduction of new technologies
and products is crucial to its success and plans to continue to make
acquisitions or strategic investments to accelerate time to market where
appropriate.

General and administrative expenses in fiscal 1998 increased $18.2 million or
seven percent from fiscal 1997. As a percentage of sales, general and
administrative expenses increased to 5.0 percent, compared to 4.4 percent in
fiscal 1997. The year-over-year increase in general and administrative expenses
in absolute dollars and dollars as a percentage of sales primarily reflected the
expansion of the Company's infrastructure, including personnel, as well as an
increased provision for bad debts.

During the fourth quarter of fiscal 1998, the Company recorded a charge of
approximately $8.4 million for purchased in-process technology associated with
the Lanworks acquisition. See Note 12 of Notes to Consolidated Financial
Statements.

During fiscal 1998, the Company recorded merger-related and other charges of
$253.7 million. These charges consisted of a merger-related charge and other
charges associated with past merger activities and disposition of real estate.
The merger-related charge of approximately $260.7 million related to the merger
with U.S. Robotics. During the fourth quarter, the Company reversed
approximately $10.6 million of previously recorded merger accruals. The Company
also sold a parcel of land near its headquarters site in Santa Clara, which
resulted in a net gain of approximately $15.8 million. Also during the fourth
quarter of fiscal 1998, the Company made a decision to close a manufacturing
site in Illinois in order to consolidate two Chicago-area manufacturing
facilities into one location. The Company recognized a charge of approximately
$19.4 million associated with this closure. See Note 12 of Notes to Consolidated
Financial Statements.

OTHER INCOME, NET

Other income, net increased $8.4 million compared to fiscal 1997, primarily as a
result of higher interest income due to higher average cash balances. Other
income, net for fiscal 1998 included a charge of approximately $4.7 million
related to an early call premium and write-off of unamortized issuance fees
associated with the redemption of $110 million of convertible notes in December
1997.

The majority of the Company's sales are denominated in U.S. Dollars. Where
available, the Company enters into foreign exchange forward contracts to hedge
certain balance sheet exposures and intercompany balances against future
movements in foreign exchange rates. Fiscal 1998 other income, net includes
foreign currency losses of approximately $12.3 million, primarily related to
Korean operations, where foreign exchange hedges were not available, or were
available only to a limited extent.

TAXES

The Company's effective income tax rate was approximately 74.1 percent in fiscal
1998 compared to 37.5 percent in fiscal 1997. Excluding the non-deductible
portion of merger-related and other charges primarily associated with the merger
with U.S. Robotics, the pro forma income tax rate was 35.0 percent for fiscal
1998. Excluding a charge for purchased in-process technology of approximately
$54.0 million and tax benefit of approximately $17.9 million associated with the
acquisition of Scorpio and the non-deductible portion of the merger-related
charge associated with the merger with OnStream, the pro forma income tax rate
was 36.9 percent for fiscal 1997.
24

NET INCOME

Net income for fiscal 1998 was $30.2 million, or $0.08 per share, compared to
net income of $500.5 million, or $1.42 per share for fiscal 1997. Excluding a
charge for purchased in-process technology and merger-related and other charges
mentioned above, net income would have been $246.1 million, or $0.67 per share
for fiscal 1998. Excluding the purchased in-process technology and tax benefit,
and the merger-related charge, net income would have been $543.2 million, or
$1.54 per share for fiscal 1997.

Comparison of fiscal years ended May 31, 1997 and 1996

SALES

Fiscal 1997 sales totaled $5.61 billion, an increase of 31 percent from fiscal
1996 sales of $4.28 billion. Sales of client access products in fiscal 1997 were
$3.15 billion, an increase of 30 percent from fiscal 1996 sales of $2.43
billion. Sales of client access products in fiscal 1997 represented 56 percent
of total sales compared to 57 percent in fiscal 1996. Sales of network systems
products in fiscal 1997 were $2.46 billion, an increase of 32 percent compared
to fiscal 1996 sales of $1.86 billion. Sales of network systems products
represented 44 percent of total sales in fiscal 1997, compared to 43 percent in
fiscal 1996. Fiscal 1997 sales growth was particularly strong in the areas of
Fast Ethernet NICs, stackable hubs and switches, modems, remote access
concentrators, ATM high-function switches and handheld connected organizers.

Sales in the U.S. represented 55 percent of total sales for fiscal 1997 compared
to 60 percent for fiscal 1996. U.S. and international sales increased 21 and 45
percent, respectively, compared to fiscal 1996. The increase in international
sales was a result of strong growth in the European and Asia Pacific regions due
to the Company's continued global expansion through the opening of new sales
offices in Asia, Latin America and Europe and the expansion of worldwide service
and support programs.

GROSS MARGIN

Gross margin as a percentage of sales was 47.9 percent in fiscal 1997 compared
to 46.6 percent in fiscal 1996. The U.S. Robotics brand modems with x2
technology were introduced in the third quarter of fiscal 1997, with
significantly higher margins, reflecting first-to-market pricing. The Company's
year-over-year gross margin increase primarily reflected an improved product
mix, specifically higher sales of certain modems, workgroup switching and hub
products and lower sales of network access concentrators and lower product
material costs of certain NICs. The increase in gross margins was partially
offset by a higher sales mix of certain lower margin NICs and increased pricing
pressures on remote access products. During the third quarter of fiscal 1997,
the Company reduced its average selling prices on Fast Ethernet NICs by
approximately 40 percent in response to increased competition, thus causing a
decline in gross margins, which was not completely reflected in fiscal 1997.

OPERATING EXPENSES

Operating expenses in fiscal 1997 were $1.89 billion, or 33.8 percent of sales,
compared to $1.39 billion, or 32.6 percent of sales in fiscal 1996. Excluding a
purchased in-process technology charge of $54.0 million associated with the
Scorpio acquisition and a merger-related charge of $6.6 million associated with
the OnStream acquisition, operating expenses would have been $1.83 billion, or
32.7 percent of sales for fiscal 1997. Excluding a purchased in-process
technology charge of $106.4 million associated with the acquisitions of Scorpio
and AXON and merger-related and other charges of $70.0 million primarily
associated with the acquisition of Chipcom, operating expenses would have been
$1.22 billion, or 28.5 percent of sales for fiscal 1996.

Sales and marketing expenses in fiscal 1997 increased $372.4 million or 53
percent from fiscal 1996. Sales and marketing expenses as a percentage of sales
increased to 19.3 percent of sales in fiscal 1997 from 16.6 percent in fiscal
1996. The year-over-year increase is attributable to the expansion of field
sales and marketing activities and personnel worldwide, as well as an increase
in spending for the Company's customer service programs. In addition, the
Company increased spending on advertising and marketing incentive programs and
promotions associated with the introduction of the x2 products.

Research and development expenses in fiscal 1997 increased $164.7 million or 49
percent compared to fiscal 1996. Research and development expenses as a
percentage of sales increased to 9.0 percent of sales compared to 7.9 percent of
sales in fiscal 1996. The year-over-year increase in research and development
expenses in absolute dollars and dollars as a percentage of sales was primarily
attributable to the cost of developing new products in the areas of client
access, switching, and network management and its expansion into new
technologies and markets.

25

General and administrative expenses in fiscal 1997 increased $79.6 million or 47
percent from fiscal 1996. As a percentage of sales, general and administrative
expenses increased to 4.4 percent, compared to 4.0 percent in fiscal 1997. The
year-over-year increase in general and administrative expenses in absolute
dollars and dollars as a percentage of sales primarily reflected the expansion
of the Company's infrastructure, including facilities, personnel, and an
increased provision for bad debts.

OTHER INCOME, NET

Other income, net was 0.2 percent of sales in both fiscal 1997 and fiscal 1996.
Other income, net for fiscal 1997 reflected increased interest income due to
higher cash and investment balances, which was offset by increased interest and
other expense due to higher levels of short-term debt. The majority of the
Company's sales are denominated in U.S. Dollars. Where available, the Company
enters into foreign exchange forward contracts to hedge certain balance sheet
exposures and intercompany balances against future movements in foreign exchange
rates. The impact of foreign exchange was not significant for fiscal 1997 or
1996.

TAXES

The Company's effective income tax rate was approximately 37.5 percent in fiscal
1997 compared to 43.0 percent in fiscal 1996. Excluding a charge for purchased
in-process technology of approximately $54.0 million and tax benefit of
approximately $17.9 million associated with the acquisition of Scorpio and the
non-deductible portion of the merger-related charge associated with the merger
with OnStream, the pro forma income tax rate was 36.9 percent for fiscal 1997.
Excluding the non-deductible purchased in-process technology charge of
approximately $106.4 million associated with the acquisitions of Scorpio and
AXON, and merger-related and other charges, primarily associated with Chipcom,
the pro forma income tax rate was 35.9 percent for fiscal 1996.

NET INCOME

Net income for fiscal 1997 was $500.5 million, or $1.42 per share, compared to
net income of $347.9 million, or $1.02 per share for fiscal 1996. Excluding the
purchased in-process technology and related tax benefit and the merger-related
charge, net income was $543.2 million, or $1.54 per share for fiscal 1997.
Excluding the purchased in-process technology and merger-related and other
charges mentioned above, net income was $504.1 million, or $1.47 per share for
fiscal 1996.

BUSINESS ENVIRONMENT AND RISK FACTORS

Financial Model. In managing its business, the Company annually establishes a
long-term financial model based on observed and anticipated trends in technology
and the marketplace. The model, which includes ranges for gross margin,
operating expenses and operating income, is not intended to be a prediction of
future financial results, rather, it is used to assist the Company's management
in making decisions about the allocation of resources and investments. The
current model is as follows:

Gross margin 45.5 - 47.5%
Operating expenses 27.5 - 29.5%
Operating income 16.0 - 20.0%

The gross margin and operating expenses ranges of the model were reduced during
fiscal 1998 to reflect, in part, increasing sales attributable to PC OEMs, the
emerging importance of the consumer and small enterprise market segment and
increased price competition. The Company is not currently operating within the
ranges of the model and does not expect that its financial results will be
within these ranges in the short-term. While the Company expects to make
progress toward these ranges in fiscal 1999, there can be no assurance that the
Company will do so or that actual results in any particular period will fall
within the ranges stated in the long-term model above.

Competition and Pricing. The Company participates in a highly volatile industry
characterized by vigorous competition for market share, rapid product and
technology development, uncertainty over adoption of industry standards and
declining prices. The Company's competition comes from start-up companies,
well-capitalized computer systems and communications companies, and other
technology companies. Many of the Company's current and potential competitors
have greater financial, marketing and technical resources than the Company.

26

The effects of intense competition in the Company's industry include aggressive
pricing practices and declining product prices, which have directly impacted the
Company's operating results. For example, the Company's results in fiscal 1998
were negatively impacted by decreasing prices in the modem market resulting in
part from increased competition for market share, particularly in the OEM
channel, and the availability of low-priced components. In addition, the
introduction of the new V.90 56 Kbps technology placed significant downward
price pressure on older products. Significant competition and decreasing prices
have also impacted other product lines, including switches, hubs and remote
access concentrators.

There can be no assurance that intense competition in the industry and
particular actions of the Company's competitors will not have an adverse effect
on the Company's business, operating results and financial condition. In
particular, the Company expects that prices on many of its products will
continue to decrease in the future and that such price decreases may have an
adverse impact on the results of operations or financial condition of the
Company.

Development and Introduction of New Products. The Company is actively engaged in
the research and development of new technologies and products. The Company's
success depends, in substantial part, on the identification of new market and
product opportunities and the development and market acceptance of new products,
such as the recently introduced CoreBuilder Layer 3 Switches. The Company's
business, operating results, or financial condition may be adversely affected by
a change in one or more of the technologies affecting network communications, a
change in market demand for products based on a particular technology, a failure
to develop new products, delays in shipping new products, or technical problems
with new products.

With the highly competitive nature of the Company's industry, new products are
routinely introduced by competitors. For example, Microsoft Corporation and its
licensees recently entered the handheld connected organizer market to compete
with the Palm Computing(R) platform, the Company's fastest growing product
category. The Company's business may be adversely impacted by the development by
competitors of products and technologies that render the Company's products
obsolete or noncompetitive.

The Company's success also depends, in part, on the adoption of industry
standards, the timely introduction of new standards-compliant products, and
market acceptance of these products. For example, the V.90 Kbps standard was
established in January 1998, and the Company introduced V.90 products in
February 1998. The Company's results have been and will continue to be affected
by the extent to which the V.90 technology is deployed by Internet service
providers and adopted by Internet and other modem users. Slow market acceptance
of new technologies and industry standards, such as the V.90 technology, can and
will have an adverse impact on the Company's results of operations or financial
condition.

Industry Consolidation and Integration of Acquired Companies. The networking
industry is in a period of significant consolidation. For example, during fiscal
1998, the Company merged with U.S. Robotics, Cisco Systems acquired nine
companies, Bay Networks acquired four companies, Lucent Technologies acquired
four companies, and Northern Telecom announced that it would acquire Bay
Networks. The Company expects that networking industry consolidation will
continue, including combinations between traditional suppliers of
telecommunications or voice networking and data networking companies. Future
business combinations may result in companies with strong competitive positions
and products. Continued consolidation may have a material adverse effect on the
Company's business, operating results or financial condition.

During fiscal 1998, the Company completed the merger with U.S. Robotics.
Achieving the benefits of an acquisition depend, in part, upon whether the
integration of the acquired business, products or technology is accomplished in
an efficient and effective manner. There can be no assurance with the Company's
recent acquisitions or any future acquisitions that the products, technologies,
distribution channels, customer support operations, management information
systems, research and development efforts and key personnel of the acquired
companies will be effectively assimilated into the Company's business or product
offerings. The failure to effectively integrate acquired companies and their
products could have a material adverse effect on the Company's business,
operating results, or financial condition.

Declining Industry Growth Rates. The Company's success is dependent, in part, on
the overall growth rate of the networking industry. In 1997 and early 1998,
industry growth was well below historical rates. There can be no assurance that
the networking industry will continue to grow or that it will again achieve
higher growth rates. The Company's business, operating results or financial
condition may be adversely affected by any further decrease in industry growth.
In addition, there can also be no assurance that the Company's results in any
particular period will fall within the ranges for growth forecast by market
researchers.
27

Reliance on Distributors, Resellers and OEMs. The Company sells a significant
portion of its products to distributors, resellers and OEMs. In recent years,
the percentage of products sold through these channels has increased. The
Company's reliance on distributors, resellers and OEMs subjects the Company to
many risks, including inventory, credit and business concentration.

The Company's distributors and resellers maintain significant levels of the
Company's products in their inventories. The Company attempts to ensure that
appropriate levels of products are available to end users by working closely
with distributors and resellers to manage inventory levels. In the second
quarter of fiscal 1998, the Company adopted a new inventory business model,
which generally calls for fewer weeks' supply of inventory in the channel and
the Company accepting some inventory risk previously held by its customers.
There can be no assurance that the Company will be successful in efforts to
manage the inventory levels of its distributors and resellers or that the
Company will be able to successfully operate its business within its inventory
business model. Any failure by the Company to do so could adversely affect the
Company's business, operating results or financial condition. In addition, the
Company's results could be negatively impacted if the Company's distributors and
resellers implement a different channel inventory model.

The distribution and reseller channels utilized by the Company have undergone a
significant level of consolidation. As a result, the Company has an increased
concentration of credit risk. While the Company monitors and attempts to manage
this risk, financial difficulties on the part of one or more of the Company's
distributors or resellers may have a material adverse effect on the Company's
results of operations or financial condition.

The Company derives an increasing portion of its sales from OEMs, including PC
companies that bundle 3Com NICs and modems, and incorporate 3Com chipsets into
their products. The Company expects that the trend toward increasing OEM sales
will continue. As a result, the Company's future operating results are
dependent, in part, on the Company's ability to establish, maintain and
strengthen relationships with OEMs. Because sales to OEMs are typically at lower
prices and result in lower margins to the Company, the Company's sales and gross
margins may be adversely impacted if, as the Company expects, OEMs continue to
become a larger percentage of the business.

Product Integration. Certain OEMs in the PC industry have, from time to time,
chosen to integrate networking and modem functions on the PC motherboard. For
example, the Company currently sells networking chipsets to Dell Computer which
are integrated directly onto the PC motherboard of Dell's high-end Optiplex line
of PCs. While no clear long-term trend has emerged, should integration become a
trend, the Company's future sales growth could be adversely impacted.

Reliance on Suppliers. Some key components of the Company's products are
currently available only from single or limited sources. In addition, certain of
the Company's suppliers are competitors of the Company. While the Company has
generally been able to obtain adequate supplies of components from existing
sources, there can be no assurance that in the future the Company's suppliers
will be able to meet the Company's demand for components in a timely and
cost-effective manner. The Company's business, operating results, financial
condition or customer relationships could be adversely affected by either an
increase in prices for, or an interruption or reduction in supply of, key
components.

International Markets. The Company operates internationally and expects that
international markets will continue to account for a significant percentage of
the Company's sales. Many international markets are characterized by economic
and political instability and currency fluctuations that can adversely affect
the Company's operating results or financial condition.

The recent instability in the Asian financial markets has negatively impacted
the Company's sales in those markets by, among other things, decreasing end-user
purchases, increasing competition from local competitors offering sales terms in
local currencies, and reducing access to sources of capital needed by customers
to make purchases. In addition to reducing sales, difficulties in Asia have
subjected the Company's resellers to financial difficulties and may increase the
Company's credit risk as customers become insolvent or otherwise have their
ability to meet obligations impaired. Should the economic environment in Asia
fail to improve, the Company may consider continuing to expand its exposure to
foreign currencies to preserve long-term customer relationships.

There can be no assurance that the instability in Asia will not continue to have
an adverse effect on the Company's operating results. In addition, there is no
assurance that similar situations in other markets will not occur and adversely
impact the Company. In particular, significant fluctuations in foreign currency
could have an adverse impact on the Company's sales and/or foreign currency
exchange exposures.
28

Ability to Satisfy Product Orders. The timing and amount of the Company's sales
are dependent on a number of factors that make estimating operating results
prior to the end of any period uncertain. For example, the Company does not
typically maintain a significant backlog and, as a result, product sales in any
quarter are dependent on orders booked and shipped in that quarter. In addition,
the Company's customers historically request fulfillment of orders in a short
period of time, resulting in limited visibility to sales trends. As a result,
the Company's operating results depend on the volume and timing of orders and
the Company's ability to fulfill the orders in a timely manner. The Company's
results of operations or financial condition would be adversely affected if
incoming order rates decline, if ordered products are not readily available, or
if the Company is not able to immediately fill orders.

From time to time, the Company has shipped a significant percentage of its
products in the third month of a fiscal quarter. This subjects the Company to
risks such as unexpected disruptions in functions including manufacturing, order
management, information systems and shipping. Should the percentage of sales in
the third month of a quarter escalate, or should a significant disruption in the
Company's functions occur, there could be an adverse affect on the Company's
results of operations or financial condition.

Inventory. In recent periods, the Company's inventory has been higher than
historical levels. High levels of inventory increase the exposure to the Company
when products in inventory become obsolete or otherwise not saleable. While the
Company expects to reduce the level of its inventory over time, there can be no
assurance that it will be successful in doing so, or that products in the
Company's inventory will not become obsolete. Failure to adequately manage the
levels of inventory could adversely impact the Company's operating results or
financial condition.

Product Warranties. The Company's products are covered by warranties, and the
Company is subject to contractual commitments to perform under such warranties.
If unexpected circumstances arise such that products do not perform as intended
and the Company is not successful in resolving product quality or performance
issues, there could be an adverse impact on the operating results or financial
condition of the Company.

Intellectual Property Rights. The Company has received, and may continue to
receive, notice of claims of infringement of other parties' proprietary rights.
Many of the Company's competitors, in particular the traditional
telecommunications companies, have large patent portfolios. The Company, from
time to time, must negotiate licenses or cross-licenses with third parties to
obtain rights to incorporate proprietary technologies, protocols or
specifications. Any failure by the Company to obtain and maintain licenses, on
favorable terms, for intellectual property rights required for the manufacture,
sale and use of its products, particularly those which must comply with industry
standard protocols and specifications to be commercially viable, could have a
material adverse effect on the Company's business, results of operations or
financial condition.

The Company may be subject to litigation based on claimed infringement of the
rights of others or to determine the scope and validity of the proprietary
rights of others. Any such litigation could be costly and cause diversion of
management's attention, either of which could have a material adverse effect on
the Company's business, results of operations or financial condition. Adverse
determinations in such litigation could subject the Company to significant
liabilities, require the Company to seek licenses from others, or prevent the
Company from manufacturing and selling its products, any one of which could have
a material adverse effect on the Company.

Electronic Commerce and Electronic Data Interchange (EDI). Many vendors,
distributors and resellers have been successful in the direct sale of products
to customers who wish to order products on the Internet or through EDI. These
trends have enabled manufacturers to increase business volume and lower their
cost structures. There can be no assurance that the Company will successfully
implement or continue to expand such systems in a timely manner, and a failure
to do so could adversely affect results of operations or financial condition.

Dependence on Key Personnel and Recruiting. The success of the Company will
depend to a significant extent upon a number of key technical employees and
management. The loss of the services of key employees could have a material
adverse effect on the Company's business, operating results or financial
condition. In addition, recruiting and retaining skilled personnel, including
qualified engineers, is highly competitive. If the Company cannot successfully
recruit and retain skilled personnel, the Company's financial results may be
adversely affected.
29

Year 2000 Compliance. As is true for most companies, the Year 2000 computer
issue creates a risk for 3Com. If systems do not correctly recognize date
information when the year changes to 2000, there could be an adverse impact on
the Company's operations. The risk for 3Com exists in four areas: systems used
by the Company to run its business, systems used by the Company's suppliers,
potential warranty or other claims from 3Com customers, and the potential
reduced spending by other companies on networking solutions as a result of
significant information systems spending on Year 2000 remediation. The Company
is currently evaluating its exposure in all of these areas.

3Com is in the process of conducting a comprehensive inventory and evaluation of
the information systems used to run its business. 3Com has a number of projects
underway to replace older systems that are known to be Year 2000 non-compliant.
Other systems, which are identified as non-compliant, will be upgraded or
replaced. For the Year 2000 non-compliance issues identified to date, the cost
of remediation is not expected to be material to the Company's operating
results. However, if implementation of replacement systems is delayed, or if
significant new non-compliance issues are identified, the Company's results of
operations or financial condition could be materially adversely affected.

3Com is also in the process of contacting its critical suppliers to determine
that the suppliers' operations and the products and services they provide are
Year 2000 compliant. Where practicable, 3Com will attempt to mitigate its risks
with respect to the failure of suppliers to be Year 2000 ready. However, such
failures remain a possibility and could have an adverse impact on the Company's
results of operations or financial condition.

The Company believes its current products are Year 2000 compliant; however,
since all customer situations cannot be anticipated, particularly those
involving third party products, 3Com may see an increase in warranty and other
claims as a result of the Year 2000 transition. In addition, litigation
regarding Year 2000 compliance issues is expected to escalate. For these
reasons, the impact of customer claims could have a material adverse impact on
the Company's results of operations or financial condition.

Year 2000 compliance is an issue for virtually all businesses, whose computer
systems and applications may require significant hardware and software upgrades
or modifications. Companies owning and operating such systems may plan to devote
a substantial portion of their information systems' spending to fund such
upgrades and modifications and divert spending away from networking solutions.
Such changes in customers' spending patterns could have a material adverse
impact on the Company's sales, operating results or financial condition.

Fluctuations in Quarterly Results. The Company's operating results for any
particular quarter are difficult to predict and may continue to be subject to
significant fluctuations. These fluctuations can be caused by a wide variety of
factors, including the volume and timing of orders, the introduction and
acceptance of new products and technologies, price competition, general
conditions and trends in the networking industry and technology sector,
disruption in international markets, general economic conditions, and
extraordinary events such as industry consolidation, acquisitions, or
litigation. For example, the first quarter of the fiscal year has traditionally
been the Company's lowest sales quarter, as it includes the three summer months
of June, July and August. These factors, and accompanying fluctuations in
periodic operating results, could have a significant adverse impact on the
market price of the Company's common stock.

LIQUIDITY AND CAPITAL RESOURCES

Cash and equivalents and short-term investments at May 31, 1998 were $1.1
billion, increasing $186.1 million from May 31, 1997. At the end of fiscal 1997,
cash and equivalents and short-term investments were $889.9 million.

For the fiscal year ended May 31, 1998, net cash generated from operating
activities was $626.2 million. Accounts receivable at May 31, 1998 decreased
$109.5 million from May 31, 1997 to $849.6 million. Days sales outstanding in
receivables decreased to 56 days at May 31, 1998, compared to 63 days at May 31,
1997. Inventory levels at May 31, 1998 increased $90.1 million, of which $70.1
million was finished goods, from the prior fiscal year-end to $644.8 million.
Average inventory turnover was 4.4 turns for the quarter ended May 31, 1998,
compared to 6.2 turns for the quarter ended May 31, 1997.

30

During the fiscal year ended May 31, 1998, the Company made $508.3 million in
capital expenditures. Major capital expenditures included upgrades and expansion
of the Company's facilities in the U.S., the U.K., Ireland and Singapore and the
continuing development of the Company's worldwide information systems. As of May
31, 1998, the Company had approximately $138 million in capital expenditure
commitments outstanding primarily associated with the construction and expansion
of facilities in the U.S. and Singapore. In addition, the Company has
commitments related to operating lease arrangements in the U.S., under which the
Company has an option to purchase the properties for an aggregate of $322.2
million, or arrange for the sale of the properties to a third party. If the
properties are sold to a third party at less than the option price, the Company
retains an obligation for the difference, subject to certain provisions of the
lease.

In April 1998, the Company purchased the property in Rolling Meadows, Illinois,
which was previously under an operating lease, and paid the owner $38.3 million
pursuant to its purchase rights.

During fiscal 1998, the Company received cash of $297.2 million from the sale of
approximately 24 million shares of its common stock to employees through its
employee stock purchase and option plans. These cash inflows related primarily
to the exercise of stock options by former employees of U.S. Robotics. Pursuant
to a change-in-control feature of the U.S. Robotics' employee stock option
plans, substantially all outstanding options held by employees of U.S. Robotics
became fully vested and exercisable upon closing of the merger in June 1997.

During the first quarter of fiscal 1998, the Company signed a lease, which
replaced a previous land lease, for 300,000 square feet of office and research
and development space and a data center to be built on land adjacent to the
Company's headquarters site in Santa Clara, California. The lease expires in
August 2002, with an option to extend the lease term for two successive periods
of five years each. The Company has an option to purchase the property for $83.6
million, or at the end of the lease arrange for the sale of the property to a
third party with the Company retaining an obligation to the owner for the
difference between the sale price and $83.6 million, subject to certain
provisions of the lease. Construction of the buildings began in July 1997, and
the Company anticipates that it will occupy the facility and begin lease
payments in the second quarter of fiscal 1999.

During the first quarter of fiscal 1998, the Company signed a lease, which
replaced a previous land lease, for 525,000 square feet of office, research and
development and manufacturing space to be built on land in Marlborough,
Massachusetts for the consolidation and expansion of existing operations. The
lease expires in August 2002, with an option to extend the lease term for two
successive periods of five years each. The Company has an option to purchase the
property for $86.0 million, or at the end of the lease arrange for the sale of
the property to a third party with the Company retaining an obligation to the
owner for the difference between the sale price and $86.0 million, subject to
certain provisions of the lease. Construction of the buildings began in the
first quarter of fiscal 1998, and the Company anticipates that it will occupy
the facility and begin lease payments in the fourth quarter of fiscal 1999.
Adjacent to this property is a leased facility consisting of 100,000 square feet
of office space. This lease expires in December 1999.

The two aforementioned leases require the Company to maintain specified
financial covenants, all of which the Company was in compliance with as of May
31, 1998.

During the fourth quarter of fiscal 1998, the Company notified the lessor of a
58-acre parcel of land near its existing headquarters in Santa Clara of its
intention to exercise its option to purchase the land for $49.5 million. On
March 26, 1998 the option was exercised, and the Company immediately sold a
portion of the land to a third party. Terms of the transaction resulted in the
Company reporting a net gain of $15.8 million on the sale of the property during
the fourth quarter of fiscal 1998. An additional gain of $4.2 million was
deferred pending the resolution of certain contingencies. The Company retained a
25-acre parcel for future development. This parcel of land is adjacent to a
14-acre parcel previously purchased by the Company.

The Company has a $100 million revolving bank credit agreement, which expires
December 20, 1999. Payment of cash dividends are permitted under the credit
agreement, subject to certain limitations based on net income levels of the
Company. The Company has not paid and does not anticipate it will pay cash
dividends on its common stock. The credit agreement requires the Company to
maintain specified financial covenants. As of May 31, 1998, there were no
outstanding borrowings under the credit agreement, and the Company was in
compliance with all required covenants. During fiscal 1998, the Company repaid
approximately $185 million of short-term and long-term borrowings incurred by
U.S. Robotics prior to the merger.
31

On December 23, 1997, the Company redeemed all of its convertible subordinated
notes totaling $110 million. Under the terms of the note agreement, the Company
paid cash of approximately $115 million for principal, accrued interest and an
early call premium. Included in other income, net for the year ended May 31,
1998 is a charge of approximately $4.7 million for the early call premium and
write-off of unamortized issuance fees.

As of May 31, 1998 approximately $50.5 million of the U.S. Robotics merger
accrual was remaining. Of this amount, approximately $18 million relates to
anticipated cash expenditures associated with the merger, of which approximately
$6 million relates to severance and outplacement costs, which the Company
expects will be paid in the first six months of fiscal 1999. See Note 12 of
Notes to the Consolidated Financial Statements.

During the fourth quarter of fiscal 1998, the Company purchased Lanworks for
approximately $13.0 million in cash. This acquisition resulted in a charge of
approximately $8.4 million during the year ended May 31, 1998, which represented
purchased in-process technology that had not yet reached technological
feasibility and had no alternative future use.

In June 1998, the Company's Board of Directors authorized the repurchase of up
to 10 million shares of the Company's stock. Such purchases will be made in the
open market from time to time.

Based on current plans and business conditions, the Company believes that its
existing cash and equivalents, short-term investments, cash generated from
operations and the available credit agreement will be sufficient to satisfy
anticipated cash requirements for at least the next twelve months.

EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS

In June 1997, the FASB issued SFAS 130, "Reporting Comprehensive Income." This
Statement establishes standards for the reporting and display of comprehensive
income and its components. SFAS 130 will be effective for the Company's fiscal
year 1999 and requires restatement of all previously reported information for
comparative purposes. This Statement will require additional disclosure but will
not have a material impact on the Company's financial position, results of
operations or cash flows.

In June 1997, the FASB issued SFAS 131, "Disclosures About Segments of an
Enterprise and Related Information." This Statement requires that financial
information be reported on the basis used internally for evaluating segment
performance and deciding how to allocate resources to segments. SFAS 131 will be
effective for the Company's fiscal year 1999 and requires restatement of all
previously reported information for comparative purposes. Management of the
Company has not yet evaluated the effects of this change on its reporting of
segments.

In June 1998, the FASB issued SFAS 133, "Accounting for Derivative Instruments
and Hedging Activities." This Statement requires companies to record derivatives
on the balance sheet as assets or liabilities, measured at fair value. Gains or
losses resulting from changes in the values of those derivatives would be
accounted for depending on the use of the derivative and whether it qualifies
for hedge accounting. SFAS 133 will be effective for the Company's fiscal year
ending May 31, 2001. Management believes that this Statement will not have a
significant impact on the Company.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk Disclosures. The following discussion about the Company's market
risk disclosures involves forward-looking statements. Actual results could
differ materially from those projected in the forward-looking statements. The
Company is exposed to market risk related to changes in interest rates, foreign
currency exchange rates and equity security price risk. The Company does not use
derivative financial instruments for speculative or trading purposes.

Interest Rate Sensitivity. The Company maintains a short-term investment
portfolio consisting mainly of income securities with an average maturity of
less than two years. These available-for-sale securities are subject to interest
rate risk and will fall in value if market interest rates increase. If market
interest rates were to increase immediately and uniformly by 10 percent from
levels at May 31, 1998, the fair value of the portfolio would decline by an
immaterial amount. The Company has the ability to hold its fixed income
investments until maturity, and therefore the Company would not expect its
operating results or cash flows to be affected to any significant degree by the
effect of a sudden change in market interest rates on its securities portfolio.

32

At May 31, 1998, the Company had approximately $200 million of outstanding
obligations under certain real estate lease arrangements with monthly payments
tied to short-term interest rates. If short-term interest rates were to increase
10 percent, the increased lease payments associated with these arrangements
would not have a material impact on the Company's net income or cash flows. In
addition, the Company also had fixed rate long-term debt of approximately $48
million, and a hypothetical 10 percent decrease in interest rates would not have
a material impact on the fair market value of this debt. The Company does not
hedge any interest rate exposures.

Foreign Currency Exchange Risk. The Company enters into foreign exchange forward
contracts to hedge certain balance sheet exposures and intercompany balances
against future movements in foreign exchange rates. Gains and losses on the
forward contracts are largely offset by gains and losses on the underlying
exposure. A hypothetical 10 percent appreciation of the U.S. Dollar from May 31,
1998 market rates would increase the unrealized value of the Company's forward
contracts by $11.8 million. Conversely, a hypothetical 10 percent depreciation
of the U.S. Dollar from May 31, 1998 market rates would decrease the unrealized
value of the Company's forward contracts by $11.8 million. In either scenario,
the gains or losses on the forward contracts are largely offset by the gains or
losses on the underlying transactions and consequently a sudden or significant
change in foreign exchange rates would not have a material impact on future net
income or cash flows.

Equity Price Risk. The Company holds a small portfolio of marketable-equity
traded securities that are subject to market price volatility. Equity price
fluctuations of plus or minus 15 percent would not have a material impact on the
Company.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of 3Com Corporation:

We have audited the consolidated balance sheets of 3Com Corporation and its
subsidiaries (the Company) as of May 31, 1998 and 1997, and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the three years in the period ended May 31, 1998. Our audits also included
the financial statement schedule listed in the Index at Item 8. These financial
statements and financial statement schedule are the responsibility of the
Company's management. Our responsibility is to express an opinion on the
financial statements and financial statement schedule based on our audits. The
consolidated financial statements give retroactive effect to the fiscal 1998
merger of 3Com Corporation and U.S. Robotics Corporation, which has been
accounted for as a pooling-of-interests as described in Note 3 to the
consolidated financial statements. We did not audit the consolidated statements
of earnings, stockholders' equity, and cash flows of U.S. Robotics Corporation
for the year ended September 29, 1996, which were combined with 3Com
Corporation's statements for the year ended May 31, 1996, and reflect revenues
of $1,977,512,000, and net earnings of $170,020,000. We also did not audit the
information in the financial statement schedule relating to U.S. Robotics
Corporation for the year ended September 29, 1996, which information is included
in 3Com Corporation's schedule for the year ended May 31, 1996. Those financial
statements and financial statement schedule were audited by other auditors whose
report has been furnished to us, and our opinion, insofar as it relates to the
amounts included for U.S. Robotics for fiscal 1996, is based solely on the
reports of such other auditors. As described in Note 3 to the consolidated
financial statements, subsequent to the issuance of the report of the other
auditors, the consolidated financial statements of U.S. Robotics for the fiscal
year ended September 29, 1996 were restated to more closely conform to the
fiscal year of 3Com Corporation for the year May 31, 1997.

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 and the reports of the other auditors provide a
reasonable basis for our opinion.

In our opinion, based on our audits and the report of the other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of 3Com Corporation and its
subsidiaries at May 31, 1998 and 1997, and the results of their operations and
their cash flows for each of the three years in the period ended May 31, 1998 in
conformity with generally accepted accounting principles. Also, in our opinion,
based on our audits and the report of the other auditors, such financial
statement schedule referenced to above, when considered in relation to the basic
consolidated financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

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 our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the results of operations and cash flows of U.S. Robotics
Corporation and Subsidiaries for the year ended September 29, 1996 in conformity
with generally accepted accounting principles. Also, in our opinion, based on

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: DESCRIPTION OF BUSINESS

Description of business. 3Com Corporation, founded in 1979, and its subsidiaries
("3Com" or "the Company") is committed to providing customers global access to
critical information through high-speed networks designed to serve large
enterprises, small/medium enterprises, consumer/small office, home office
(SOHO), and carrier/service providers. 3Com offers a broad range of products
which include switches, hubs, remote access concentrators, routers, network
interface cards, modems and network management software for Ethernet, Fast
Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), Asynchronous
Transfer Mode (ATM), Digital Subscriber Line (xDSL), cable and other high-speed
technologies, and handheld connected organizers. Headquartered in Santa Clara,
California, 3Com has worldwide research and development, manufacturing,
marketing, sales and support capabilities.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

Fiscal year. Effective June 1, 1997, the Company adopted a 52-53 week fiscal
year ending on the Sunday nearest to May 31. Effective June 1, 1998, the Company
adopted a 52-53 week fiscal year ending on the Friday nearest to May 31. The
Company does not expect this change to have a significant effect on the
Company's consolidated financial statements.

Use of estimates in the preparation of financial statements. 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 could differ
from those estimates.

Principles of consolidation. The consolidated financial statements include the
accounts of 3Com Corporation and its wholly-owned subsidiaries. All significant
intercompany balances and transactions are eliminated in consolidation.

Cash equivalents are highly liquid debt investments acquired with a maturity of
three months or less.

Short-term investments consist of investments acquired with maturities exceeding
three months but less than two years. While the Company's intent is to hold debt
securities to maturity, consistent with Statement of Financial Accounting
Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and Equity
Securities," the Company has classified all securities as available-for-sale, as
the sale of such securities may be required prior to maturity to implement
management strategies. Such securities are reported at fair value with
unrealized gains or losses excluded from earnings and reported as a separate
component of stockholders' equity, net of applicable taxes.

Concentration of credit risk and major customers. Financial instruments, which
potentially subject the Company to concentrations of credit risk consist
principally of temporary cash investments and accounts receivable. The Company
invests in instruments with an investment credit rating of AA and better. The
Company also places its investments for safekeeping with high-credit-quality
financial institutions, and by policy, limits the amount of credit exposure from
any one financial institution.

Due to consolidation in the distribution and reseller channels, the Company's
increased volume of sales into these channels, and the merger with U.S.
Robotics, the Company has experienced an increased concentration of credit risk,
and, as a result, may maintain individually significant receivable balances with
such distributors and resellers. While the Company frequently monitors and
manages this risk, financial difficulties on the part of one or more of the
Company's distributors and resellers may have a material adverse effect on the
Company. As of and for the year ended May 31, 1998, the Company had one customer
which accounted for 14 percent of total sales and 14 percent of total accounts
receivable. The same customer accounted for 13 percent and 12 percent of total
sales for the fiscal years ended May 31, 1997 and 1996, respectively.

Inventories are stated at the lower of standard cost (which approximates
first-in, first-out cost) or market.

Property and equipment is stated at cost. Equipment under capital leases is
stated at the lower of fair market value or the present value of the minimum
lease payments at the inception of the lease.

41

Depreciation and amortization are computed over the shorter of the estimated
useful lives, lease terms, or terms of license agreements of the respective
assets, on a straight-line basis - generally 2-15 years, except for buildings
which are depreciated over 25 years.

Intangible assets. Purchased technology and goodwill are included in other
assets. Purchased technology is amortized over the useful life, generally four
years. Goodwill is amortized over 10 years.

Revenue recognition. The Company generally recognizes a sale when the product
has been shipped, no material vendor or post-contract support obligations remain
outstanding, except as provided by a separate service agreement, and collection
of the resulting receivable is probable. The Company accrues related product
return reserves, warranty and royalty expenses at the time of sale. Service and
subscription revenue is recognized over the contract term. The Company extends
limited product return and price protection rights to certain distributors and
resellers. Such rights are generally limited to a certain percentage of sales
over a three to six-month period. The Company warrants products for periods
ranging from 90 days to life, depending upon the product.

Foreign currency translation. The majority of the Company's sales are
denominated in U.S. Dollars. For foreign operations with the local currency as
the functional currency, assets and liabilities are translated at year-end
exchange rates, and statements of income are translated at the average exchange
rates during the year. Gains or losses resulting from foreign currency
translation are accumulated as a separate component of stockholders' equity.

For foreign operations with the U.S. Dollar as the functional currency, assets
and liabilities are translated at the year-end exchange rates except for
inventories, prepaid expenses, and property and equipment, which are translated
at historical exchange rates. Statements of income are translated at the average
exchange rates during the year except for those expenses related to balance
sheet amounts that are translated using historical exchange rates. Gains or
losses resulting from foreign currency translation are included in other income,
net in the statements of income. Foreign currency losses were $12.3 million for
the year ended May 31, 1998 and were not significant for the years ended May 31,
1997 and 1996.

Where available, the Company enters into foreign exchange forward contracts to
hedge certain balance sheet exposures and intercompany balances against future
movements in foreign exchange rates.

Stock-based compensation. The Company accounts for its employee stock plans
under the intrinsic value method prescribed by Accounting Principles Board (APB)
Opinion No. 25, "Accounting for Stock Issued to Employees."

Net income per share. In 1997, the Financial Accounting Standards Board (FASB)
issued SFAS 128, "Earnings Per Share." SFAS 128 replaced the previously reported
primary and fully diluted earnings per share with basic and diluted earnings per
share. Basic earnings per share is computed using the weighted average number of
common shares. Diluted earnings per share is computed using the weighted average
number of common shares and potentially dilutive common shares outstanding
during the period. Potentially dilutive common shares consist of employee stock
options, restricted stock, warrants, and convertible securities. All earnings
per share amounts for all periods have been presented, and where necessary,
restated to conform to SFAS 128 requirements.

Effects of recent accounting pronouncements. In June 1997, the FASB issued SFAS
130, "Reporting Comprehensive Income." This Statement establishes standards for
the reporting and display of comprehensive income and its components. SFAS 130
will be effective for the Company's fiscal year 1999 and requires restatement of
all previously reported information for comparative purposes. This Statement
will require additional disclosure but will not have a material impact on the
Company's financial position, results of operations or cash flows.

In June 1997, the FASB issued SFAS 131, "Disclosures About Segments of an
Enterprise and Related Information." This Statement requires that financial
information be reported on the basis used internally for evaluating segment
performance and deciding how to allocate resources to segments. SFAS 131 will be
effective for the Company's fiscal year 1999 and requires restatement of all
previously reported information for comparative purposes. Management of the
Company has not yet evaluated the effects of this change on its reporting of
segments.
42

In June 1998, the FASB issued SFAS 133, "Accounting for Derivative Instruments
and Hedging Activities." This Statement requires companies to record derivatives
on the balance sheet as assets or liabilities, measured at fair value. Gains or
losses resulting from changes in the values of those derivatives would be
accounted for depending on the use of the derivative and whether it qualifies
for hedge accounting. SFAS 133 will be effective for the Company's fiscal year
ending May 31, 2001. Management believes that this Statement will not have a
significant impact on the Company.

Reclassifications. Certain prior year amounts have been reclassified to conform
to the current year presentation.

NOTE 3: BUSINESS COMBINATIONS

Unless otherwise stated, for acquisitions accounted for under the
pooling-of-interests method, all financial data of the Company has been restated
to include the historical financial data of these acquired companies. No
significant adjustments were required to conform the accounting policies of the
acquired companies. For acquisitions accounted for as purchases, the Company's
consolidated results of operations include the operating results of the acquired
companies from their acquisition dates. Acquired assets and liabilities were
recorded at their estimated fair values at the dates of acquisition, and the
aggregate purchase price plus costs directly attributable to the completion of
acquisitions have been allocated to the assets and liabilities acquired.

For the Year Ended May 31, 1998. On June 12, 1997, the Company completed the
merger with U.S. Robotics Corporation (U.S. Robotics), the leading supplier of
products and systems for accessing information across the wide area network,
including modems and remote access products. This merger was accounted for as a
pooling-of-interests. The Company issued approximately 158 million shares of its
common stock in exchange for all outstanding common stock of U.S. Robotics. The
Company also assumed all options to purchase U.S. Robotics' stock, which were
converted into options to purchase approximately 31 million shares of the
Company's common stock, pursuant to the terms of the merger.

All financial data of the Company have been restated to include the historical
financial information of U.S. Robotics in accordance with generally accepted
accounting principles and pursuant to Regulation S-X. The 3Com statement of
income for the fiscal year ended May 31, 1996 has been combined with the U.S.
Robotics statement of income for the fiscal year ended September 29, 1996. The
3Com statement of income for the fiscal year ended May 31, 1997 has been
combined with the U.S. Robotics statement of income for the period from July 1,
1996 through May 25, 1997. This combining methodology includes the last three
reported quarters of U.S. Robotics, ended September 29, 1996, December 29, 1996,
and March 30, 1997, and the months of April and May 1997. To reflect a complete
12-month year and a three-month fourth quarter and thereby enhance comparability
of periodic reported results, U.S. Robotics' results of operations for the month
ended March 30, 1997 are included in both the three-month period ended March 30,
1997 and the three-month period ended May 25, 1997. This presentation has the
effect of including U.S. Robotics' results of operations for the three-month
period ended September 29, 1996 in both the combined years ended May 31, 1997
and 1996, and reflects sales of $611.4 million and net income of $13.5 million.
The aggregate of net income for the three-month period ended September 29, 1996
of $13.5 million and the one-month period ended March 30, 1997 of $112.9 million
has been reported as a decrease to the Company's fiscal 1997 retained earnings.
3Com's balance sheet as of May 31, 1997 was combined with U.S. Robotics' balance
sheet as of May 25, 1997. The combining periods are as follows:

FISCAL 1996 FISCAL 1997 QUARTERLY PERIODS

U.S. Robotics Sept `96 Sept `96 Dec `96 Mar `97 May `97*

*Three-month period which includes March, April, and May.

The results of operations for the fiscal year ended May 31, 1998 contain the
combined results of both 3Com and U.S. Robotics for the entire 12 months.

(1) Adjusted for effect of exchange ratio of 1.75 shares of 3Com common stock
for each share of U.S. Robotics common stock.

On March 2, 1998, the Company acquired substantially all of the assets and
assumed substantially all of the liabilities of Lanworks Technologies, Inc.
(Lanworks). The aggregate purchase price of $13.0 million consisted of cash
which was paid using funds from the Company's working capital. Approximately
$8.4 million of the total purchase price represented purchased in-process
technology that had not yet reached technological feasibility and had no
alternative future use and was charged to the Company's operations in the fourth
quarter of fiscal 1998. The acquisition was accounted for as a purchase.
Lanworks developed, manufactured, and marketed PC network boot technologies and
products, which are critical components of a complete desktop management
environment.

For the Year Ended May 31, 1997. On October 31, 1996, the Company acquired
OnStream Networks, Inc. (OnStream) by issuing approximately 3.3 million shares
of its common stock in exchange for all the outstanding stock of OnStream. The
Company also assumed and exchanged all options to purchase OnStream stock for
options to purchase approximately 400,000 shares of the Company's common stock.
The acquisition was accounted for as a pooling-of-interests. Financial data of
the Company has been restated for the quarter ended August 31, 1996 to include
the historical financial information of OnStream for that period, in accordance
with generally accepted accounting principles and pursuant to Regulation S-X.
Such restatement increased the Company's sales and decreased net income by $3.2
million and $1.5 million, respectively, for the quarter ended August 31, 1996.
Financial information as of May 31, 1997 and for the year then ended reflects
the Company's and OnStream's operations for those periods. As the historical
operations of OnStream were not significant to any period presented, the
Company's financial statements for periods prior to fiscal 1997 have not been
restated. The financial effect of the results of operations of OnStream prior to
fiscal 1997 has been accounted for as a $16.4 million charge against retained
earnings in fiscal 1997. As a result of the acquisition, in the second quarter
of fiscal 1997 the Company recorded acquisition-related charges, primarily
transaction costs, totaling $6.6 million. OnStream was a provider of ATM and
broadband wide area network (WAN) and access products.

During the year ended May 31, 1997, U.S. Robotics acquired substantially all of
the assets and assumed substantially all of the liabilities of four
international distributors in Korea, Japan, Australia, and Sweden. The aggregate
purchase price of $13.4 million consisted of cash, net of cash acquired, which
was paid with funds from working capital, and issuance of stock with a fair
value of $0.1 million. These purchases resulted in $14.0 million of goodwill,
which is currently being amortized over the expected useful life, estimated at
10 years.
44

For the Year Ended May 31, 1996. On June 9, 1995, the Company acquired Primary
Access Corporation (Primary Access) by issuing approximately 4.6 million shares
of its common stock for all of the outstanding stock of Primary Access. The
Company also assumed and exchanged all options and warrants to purchase Primary
Access stock for options and warrants to purchase approximately 1.0 million
shares of the Company's common stock. The acquisition was accounted for as a
pooling-of-interests. Primary Access developed, manufactured and marketed
network access systems.

On October 13, 1995, the Company acquired Chipcom Corporation (Chipcom) by
issuing approximately 18.3 million shares of its common stock in exchange for
all the outstanding common stock of Chipcom. The Company also assumed and
exchanged all options to purchase Chipcom common stock for options to purchase
approximately 2.4 million shares of the Company's common stock. The acquisition
was accounted for as a pooling-of-interests. The results of operations of
Chipcom for the five-month period ended May 31, 1995 reflected sales of $118.1
million and net income of $2.4 million, and has been reported as an increase to
the Company's fiscal 1996 retained earnings. As a result of the acquisition,
during the second quarter of fiscal 1996, the Company recorded merger-related
charges of approximately $69.0 million. See Note 12. Chipcom designed,
manufactured and distributed computer networking multifunction platforms.

On February 29, 1996, U.S. Robotics issued approximately 694,000 shares of its
common stock (approximately 1.2 million shares, adjusted for effect of exchange
ratio of 1.75 shares of 3Com common stock for each share of U.S. Robotics common
stock) in exchange for all of the outstanding capital stock of Amber Wave
Systems, Inc. (Amber Wave). The transaction was accounted for as a
pooling-of-interests. Since the aggregated historical operations of Amber Wave
prior to the date of combination were not material to the Company's consolidated
results of operations and financial position, prior period financial statements
have not been restated. Amber Wave developed technology related to local area
network (LAN) switching products.

On March 12, 1996, the Company acquired substantially all of the assets and
assumed substantially all of the liabilities of AXON Networks, Inc. (AXON). The
aggregate purchase price of $65.3 million consisted of cash, net of cash
acquired, of approximately $60.2 million, which was paid using funds from the
Company's working capital, assumption of stock options with a fair value of
approximately $3.7 million, and $1.4 million of costs directly attributable to
the completion of the acquisition. Approximately $52.4 million of the total
purchase price represented purchased in-process technology that had not yet
reached technological feasibility and had no alternative future use and was
charged to the Company's operations in the fourth quarter of fiscal 1996. The
acquisition was accounted for as a purchase. AXON developed, manufactured and
marketed remote network management and data network traffic management products.

On August 29, 1996, U.S. Robotics completed the acquisition of Scorpio
Communications Ltd. (Scorpio). The purchase price of $74.5 million consisted of
tangible and identifiable intangible net assets of $750,000, developed
technology of $16 million, purchased in-process technology of $54 million, and
goodwill of $3.8 million. The purchased in-process technology was expensed upon
acquisition. The aggregate purchase price, including direct costs of
acquisition, was paid through available cash resources and proceeds from
short-term borrowings. The acquisition was accounted for as a purchase. Scorpio
designed, manufactured and sold scalable, fully redundant, fault-tolerant ATM
switches that targeted workgroup LAN, corporate backbone and WAN access
environments.

========== ==========

In the fourth quarter of fiscal 1998, the Company committed to a strategy to
consolidate its manufacturing operations in the Chicago area. As a result of
this decision, the Company decided to dispose of its Morton Grove office and
manufacturing facility. Although this asset's carrying cost of approximately
$32.2 million had been deemed recoverable through the operations of the division
that previously occupied the facility, the decision to dispose of the asset
resulted in the recognition of a loss of approximately $19.4 million, reflecting
the difference between the estimated net realizable value and the carrying value
of the plant.

In March 1998, the Company acquired a 58-acre parcel of land near its existing
headquarters in Santa Clara pursuant to its purchase rights under a pre-existing
operating lease of the land. The Company entered into a cash sale for a portion
of the land and recognized a gain of approximately $15.8 million on the sale of
the property. An additional $4.2 million gain was deferred pending the
resolution of certain contingencies. The remaining 25-acre portion of land, in
addition to a 14-acre parcel of land already owned by the Company, will be held
for future development.

The aggregate loss of $3.6 million associated with these two transactions was
included as a component of merger-related charges and other. See Note 12.

NOTE 8: BORROWING ARRANGEMENTS AND COMMITMENTS

During the first quarter of fiscal 1998, the Company signed a lease, which
replaced a previous land lease, for 300,000 square feet of office and research
and development space and a data center to be built on land adjacent to the
Company's headquarters site in Santa Clara, California. The lease expires in
August 2002, with an option to extend the lease term for two successive periods
of five years each. The Company has an option to purchase the property for $83.6
million, or at the end of the lease arrange for the sale of the property to a
third party with the Company retaining an obligation to the owner for the
difference between the sale price and $83.6 million, subject to certain
provisions of the lease. Construction of the buildings began in July 1997, and
the Company anticipates that it will occupy and begin lease payments in the
second quarter of fiscal 1999.

During the first quarter of fiscal 1998, the Company signed a lease, which
replaced a previous land lease, for 525,000 square feet of office, research and
development and manufacturing space to be built on land in Marlborough,
Massachusetts for the consolidation and expansion of existing operations. The
lease expires in August 2002, with an option to extend the lease term for two
successive periods of five years each. The Company has an option to purchase the
property for $86.0 million, or at the end of the lease arrange for the sale of
the property to a third party with the Company retaining an obligation to the
owner for the difference between the sale price and $86.0 million, subject to
certain provisions of the lease. Construction of the buildings began in the
first quarter of fiscal 1998, and the Company anticipates that it will occupy
and begin lease payments in the fourth quarter of fiscal 1999. Adjacent to this
property is a leased facility consisting of 100,000 square feet of office space.
This lease expires in December 1999.

The two aforementioned leases require the Company to maintain specified
financial covenants, all of which the Company was in compliance with as of May
31, 1998. Future minimum lease payments are included in the table below.

The Company leases certain of its facilities and equipment under operating
leases. Leases expire at various dates from 1998 to 2021 and certain facility
leases have renewal options with rentals based upon changes in the Consumer
Price Index or the fair market rental value of the property.

Future operating lease commitments are as follows:

As of May 31, 1998, the Company had approximately $138 million in capital
expenditure commitments, primarily associated with the construction and
expansion of office and manufacturing space in the United States and Singapore.

The Company has a $100 million revolving bank credit agreement which expires
December 20, 1999. Payment of cash dividends are permitted under the credit
agreement, subject to certain limitations based on net income levels of the
Company. The Company has not paid and does not anticipate it will pay cash
dividends on its common stock. The credit agreement requires the Company to
maintain specified financial covenants. As of May 31, 1998, there were no
outstanding borrowings under the credit agreement, and the Company was in
compliance with all required covenants.

As of May 31, 1997, short term borrowings under an unsecured $300 million
syndicated revolving line of credit with a group of banks totaled $125 million.
On June 13, 1997, the Company paid all outstanding borrowings under this
revolving line of credit, totaling $80 million and immediately terminated this
agreement.

As of May 31, 1997, short-term borrowings under $90 million of uncommitted lines
of credit from a group of banks totaled approximately $10 million. On June 13,
1997, the Company paid all outstanding borrowings under these uncommitted lines
of credit, totaling $88 million and immediately terminated these agreements.

In November 1994, the Company completed a private placement of $110 million
aggregate principal amount of convertible subordinated notes under Rule 144A of
the Securities Act of 1933. Beginning in November 1997, the notes became
redeemable at the option of the Company at an initial redemption price of
102.929% of the principal amount. On December 23, 1997, the Company redeemed all
of the convertible subordinated notes. Under the terms of the note agreement,
the Company paid cash of approximately $115 million for principal, accrued
interest and early call premium. Included in other income, net for the year
ended May 31, 1998 is a charge of approximately $4.7 million for the early call
premium and write-off of unamortized issuance fees. As of May 31, 1997, there
was $110 million outstanding under this arrangement.

On July 7, 1994, the Company arranged a private placement of $60 million in
7.52% Unsecured Senior Notes with three insurance companies. The notes are
payable in five equal installments beginning in June 1997. As of May 31, 1998
and 1997, borrowings under these notes totaled approximately $48 million and $60
million, respectively. $12 million of this debt is classified as current portion
of long-term obligations as of May 31, 1998 and 1997.

The Company had a $5 million loan with a bank at an interest rate of 8.61%. As
of May 31, 1998, there was no outstanding balance under this loan. As of May 31,
1997, borrowings under this loan totaled approximately $5 million.

NOTE 9: COMMON STOCK

On September 26, 1996, the Company's Board of Directors approved an amendment to
the Company's articles of incorporation establishing a par value of $.01 per
share for the Company's common stock. On June 11, 1997, the shareholders of the
Company approved a proposal to change the Company's state of incorporation from
California to Delaware. The reincorporation was effected immediately prior to
the consummation of the merger with U.S. Robotics and, among other things,
resulted in an increase in the number of authorized shares of its common stock
from 400 million to 990 million, and preferred stock from 3 million to 10
million.

Shareholder Rights Plan. In September 1989, the Company's Board of Directors
approved an amendment and restatement of the stock purchase rights plan and
declared a dividend distribution of one common stock purchase right for each
outstanding share of its common stock. The Company's Board of Directors approved
an amendment and restatement of the rights plan in December 1994. The rights
become exercisable based on certain limited conditions related to acquisitions
of stock, tender offers and certain business combination transactions of the
Company. In the event one of the limited conditions is triggered, each right
entitles the registered holder to purchase for $250 a number of shares of 3Com
common stock (or any acquiring company) with a fair market value of $500. The
rights are redeemable at the Company's option for $.01 per right and expire on
December 13, 2004.

Stock Option Plans. The Company has stock option plans under which employees and
directors may be granted options to purchase common stock. Options are generally
granted at not less than the fair market value at grant date, vest over a two-
to five-year period, and expire ten years after the grant date.

49

On December 17, 1997, the Company's Board of Directors approved the repricing of
certain employee stock options with an exercise price in excess of the fair
market value of the Company's common stock on January 12, 1998. The exercise
price for 20.9 million shares of employee stock options was reset to $29.375,
the closing market price on January 12, 1998. All such options retain their
original vesting schedules but are subject to a nine-month period in which
exercises are prohibited. Stock options held by executive officers and directors
were not eligible for such repricing.

A summary of option transactions under the plans follows:

and 1996 with weighted average exercise prices of $10.83 and $6.45 per share,
respectively.

Employee Stock Purchase Plan. The Company has an employee stock purchase plan,
under which eligible employees may authorize payroll deductions of up to 10
percent of their compensation, as defined, to purchase common stock at a price
of 85 percent of the lower of the fair market value as of the beginning or the
end of the offering period.

Restricted Stock Plan. The Company has a restricted stock plan, under which
shares of common stock are reserved for issuance at no cost to key employees.
Compensation expense, equal to the fair market value on the date of the grant,
is recognized as the granted shares vest over a one-to-four year period.

Common Stock Reserved for Issuance. As of May 31, 1998, the Company had common
stock reserved for issuance as follows:

========

Stock Repurchase Program. In June 1998, the Company's Board of Directors
authorized the repurchase of up to 10 million shares of the Company's stock.
Such purchases will be made in the open market from time to time.

Accounting for Stock-Based Compensation. As permitted under SFAS 123, the
Company has elected to follow APB 25 and related Interpretations in accounting
for stock-based awards to employees. Under APB 25, the Company generally
recognizes no compensation expense with respect to such awards.

Pro forma information regarding net income and earnings per share is required by
SFAS 123. This information is required to be determined as if the Company had
accounted for its stock-based awards to employees (including employee stock
options and shares issued under the Employee Stock Purchase Plan, collectively
called "options") granted subsequent to May 31, 1995 under the fair value method
of that Statement. The fair value of options granted in fiscal years 1998, 1997
and 1996 reported below has been estimated at the date of grant using the
Black-Scholes option pricing model with the following assumptions:


Employee Stock Option Plans Employee Stock Purchase Plan
--------------------------- ----------------------------
1998 1997 1996 1998 1997 1996
-----------------------------------------------------------

Risk-free interest rate 5.5% 6.1% 5.4% 5.5% 5.4% 5.4%
Volatility 56.0% 54.0% 54.0% 56.0% 54.0% 54.0%
Dividend yield 0.0% 0.0% 0.0% 0.0% 0.0% 0.0%


As of May 31, 1998, the expected lives of options under the Employee Stock
Option Plan are estimated at approximately three years after the vesting date
for directors and approximately one year after the vesting date for
non-directors. As of May 31, 1997 and 1996, the expected life of options under
the Employee Stock Option Plan is estimated at one year after the vesting date.
As of May 31, 1998, 1997 and 1996, the expected life of options under the
Employee Stock Purchase Plan was estimated at six months.

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options that have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions, including the expected stock price volatility. Because
the Company's options have characteristics significantly different from those of
traded options, and because changes in the subjective input assumptions can
materially affect the fair value estimate, in the opinion of management, the
existing models do not necessarily provide a reliable single measure of the fair
value of its options. The weighted average estimated fair value of employee
stock options granted during fiscal years 1998, 1997 and 1996 was $17.97, $26.99
and $19.39 per share, respectively. The weighted average estimated fair value of
shares granted under the Employee Stock Purchase Plan during fiscal years 1998,
1997, and 1996 was $10.56, $12.46, and $12.84, respectively.

51


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

1998 1997 1996
-------- -------- --------

Net income (loss): As reported $ 30,214 $500,533 $347,875
Pro forma (61,628) 446,253 327,285

Earnings (loss) per share: As reported - basic $ 0.09 $ 1.51 $ 1.10
Pro forma - basic (0.18) 1.35 1.04

As reported - diluted $ 0.08 $ 1.42 $ 1.02
Pro forma - diluted (0.18) 1.26 0.96


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 May 31, 1995, the
full effect on pro forma net income and earnings per share will not be reflected
until fiscal 1999.

NOTE 10: FOREIGN EXCHANGE CONTRACTS

The Company does not use derivative financial instruments for speculative or
trading purposes. Where available, the Company enters into foreign exchange
forward contracts to hedge certain balance sheet exposures and intercompany
balances against future movements in foreign exchange rates. Gains and losses on
the foreign exchange contracts are included in other income, net, which offset
foreign exchange gains or losses from revaluation of foreign
currency-denominated balance sheet items and intercompany balances. The
contracts require the Company to exchange foreign currencies for U.S. Dollars or
vice versa, and generally mature in one month. At May 31, 1998 and 1997, the
Company had outstanding foreign exchange forward contracts of $159.3 million and
$27.7 million which have remaining maturities of one month. At May 31, 1998 and
1997, the Company did not have any outstanding foreign exchange forward
contracts with maturities greater than one month.

NOTE 11: FINANCIAL INSTRUMENTS FAIR VALUE DISCLOSURE

The following summary disclosures are made in accordance with the provisions of
SFAS No. 107, "Disclosures About Fair Value of Financial Instruments," which
requires the disclosure of fair value information about both on- and off-balance
sheet financial instruments where it is practicable to estimate the value. Fair
value is defined in SFAS 107 as the amount at which an instrument could be
exchanged in a current transaction between willing parties, rather than in a
forced or liquidation sale, which is not the Company's intent.

52


Because SFAS 107 excludes certain financial instruments and all non-financial
instruments from its disclosure requirements, any aggregation of the fair value
amounts presented would not represent the underlying value to the Company.

Cash and equivalents. The carrying amounts reported in the balance sheets for
cash and equivalents approximate their estimated fair values.

Short-term investments, corporate equity securities, debt and convertible
subordinated notes, and foreign exchange contracts. The fair value of short-term
investments, corporate equity securities, debt and convertible subordinated
notes, and foreign exchange contracts are based on quoted market prices.

NOTE 12: PURCHASED IN-PROCESS TECHNOLOGY, MERGER-RELATED CHARGES AND OTHER

Purchased In-Process Technology

During the fourth quarter of fiscal 1998, the Company purchased Lanworks for
approximately $13.0 million in cash. Approximately $8.4 million of the total
purchase price represented purchased in-process technology that had not yet
reached technological feasibility and had no alternative future use. This amount
was charged to the Company's operations in the fourth quarter of fiscal 1998.

During the fiscal year ended May 31, 1997, U.S. Robotics acquired Scorpio for
$74.5 million, which was accounted for as a purchase. Approximately $54.0
million of the total purchase price represented purchased in-process technology
that had not yet reached technological feasibility and had no alternative future
use. This amount was charged to the Company's operations in the first quarter of
fiscal 1997.

During the fiscal year ended May 31, 1996, the Company incurred a charge of
$106.4 million for purchased in-process technology relating to 3Com's
acquisition of AXON and U.S. Robotics' acquisition of Scorpio. Both transactions
were accounted for as purchases. Purchased in-process technology of $52.4
million and $54.0 million for AXON and Scorpio, respectively, had not yet
reached technological feasibility, had no alternative future use, and was
charged to operations during the fourth quarter of fiscal 1996.

53

Merger-Related Charges

During the fiscal year ended May 31, 1998, the Company recorded merger-related
charges of $260.7 million, which includes approximately $217.1 million of
integration expenses and $43.6 million of direct transaction costs (consisting
primarily of investment banking and other professional fees). Integration
expenses included:

+ $48.3 million related to the closure and elimination of owned and
leased facilities, primarily duplicate corporate headquarters and
domestic and European sales offices;
+ $61.8 million for severance and outplacement costs related to the
merger, including amounts related to termination benefits associated
with employment agreements. Employee groups impacted by the merger
include personnel involved in duplicate corporate services,
manufacturing and logistics, product organizations and sales;
+ $41.8 million associated with certain long-term assets, primarily
including duplicate finance, manufacturing, human resource and other
management information systems, and capitalized purchased research
and development costs related to a discontinued product; and
+ $65.2 million primarily associated with the elimination and
phase-out of duplicate wide area networking products (i.e., 3Com's
AccessBuilder(R) 2000, 4000, 5000 and 8000 products and U.S.
Robotics'(R) TOTALswitch, ATM switch, LANLinker and related small
office home office products), and the discontinuance of U.S.
Robotics' telephony products. The charge primarily includes inventory
write-offs and noncancelable purchase commitments.

The remaining merger-related accrual at May 31, 1998 was approximately $50.5
million. Total expected cash expenditures relating to the merger charge are
estimated to be approximately $120 million, of which approximately $102 million
was disbursed prior to May 31, 1998. Termination benefits paid to 838 employees
terminated through May 31, 1998 (approximately 89 percent of the total planned
severances) were approximately $55 million. The remaining severance and
outplacement amounts are expected to be paid within the first six months of
fiscal 1999.

Merger-related charges for the year ended May 31, 1997 consisted of direct
transaction costs of $6.6 million, primarily investment banking and other
professional fees, related to the acquisition of OnStream.

Merger-related charges for the year ended May 31, 1996 consisted of acquisition
costs of $69.0 million related to the acquisition of Chipcom. The $69.0 million
charge included $60.8 million of exit expenses and $8.2 million of direct
transaction costs, primarily for investment banking and other professional fees.
Exit expenses included approximately $37.8 million of costs of eliminating
duplicate and discontinued products, $5.1 million of severance and related costs
for approximately 80 employees primarily associated with duplicate or
discontinued product lines, field sales and administrative functions, $4.3
million of costs of eliminating duplicate facilities and $13.6 million of other
acquisition-related costs. In addition to the acquisition-related charges in
fiscal 1996 was a charge of approximately $1.0 million for a litigation
settlement.

Other Charges

During fiscal 1998, the Company recorded a net gain of $7.0 million associated
with past merger activities and disposition of real estate. The Company reversed
approximately $10.6 million of previously recorded merger accruals. The Company
also sold land in Santa Clara near its headquarters resulting in a net gain of
$15.8 million. In addition, consistent with the Company's consolidation of
manufacturing activities, a decision to close one of two manufacturing plants in
Chicago resulted in a one-time charge of $19.4 million, reflecting the
difference between the estimated net realizable value and the carrying value of
the plant.

The valuation allowance relates primarily to the remaining portion of net
operating losses, as the Company believes that, due to various limitations, it
is more likely than not that such benefits will not be realized. The allowance
also relates to certain expenses, the realization of which is not assured on
future state income tax returns. The valuation allowance increased $29.0 million
in fiscal 1998 and increased $1.0 million in fiscal 1997.

The Company's income taxes payable for federal, state, and foreign purposes have
been reduced by the tax benefits associated with the exercise of employee stock
options and with disqualifying dispositions of stock options. The amount of the
benefit is the tax effect of the difference between the market value of the
stock issued at the time of option exercise and the exercise price of the
option.

The provision for income taxes differs from the amount computed by applying the
federal statutory income tax rate to income before taxes as follows:

Years ended May 31,

---- ---- ----
Tax computed at federal statutory rate 35.0% 35.0% 35.0%

Total 74.1% 37.5% 43.0%
==== ==== ====

Income before income taxes for the fiscal years ended May 31, 1998, 1997 and
1996 includes income of $170.5 million, $316.9 million, and $218.3 million,
respectively from the Company's foreign subsidiaries. The Company has not
provided for federal income taxes on approximately $299.5 million of
undistributed earnings of its foreign subsidiaries. The Company intends to
reinvest in foreign subsidiary operations indefinitely. It is not practicable to
estimate the income tax liability that might be incurred upon the remittance of
such earnings.

The Company has operating loss carryforwards related to various taxing
jurisdictions, the total of which is approximately $604 million. These
carryforwards expire through the year 2013.

acquisitions of U.S. Robotics in fiscal year 1998 and Chipcom in fiscal year
1996, approximately $217.5 million and $63.0 million of merger-related costs
were charged to the United States operations in fiscal 1998 and 1996,
respectively. Transfers between geographic areas are accounted for at prices
representative of unaffiliated party transactions. See Note 3 and Note 12.

NOTE 16: LITIGATION

The Company is a party to lawsuits in the normal course of its business. The
Company believes that it has meritorious defenses in all lawsuits in which the
Company or its subsidiaries is a defendant. The Company notes that (i)
litigation in general and intellectual property and securities litigation in
particular can be expensive and disruptive to normal business operations and
(ii) the results of complex legal proceedings can be very difficult to predict
with any certainty.

Securities Litigation

On March 24 and May 5, 1997, putative securities class action lawsuits,
captioned Hirsch v. 3Com Corporation, et al., Civil Action No. CV764977
(Hirsch), and Kravitz v. 3Com Corporation, et al., Civil Action No. CV765962
(Kravitz), respectively, were filed against the Company and certain of its
officers and directors in the California Superior Court, Santa Clara County. The
complaints allege violations of Sections 25400 and 25500 of the California
Corporations Code and seek unspecified damages on behalf of a purported class of
purchasers of 3Com common stock during the period from September 24, 1996
through February 10, 1997. The actions are in discovery. No trial date has been
set.

On February 10, 1998, a putative securities class action, captioned Euredjian v.
3Com Corporation, et al., Civil Action No. C-98-00508CRB (Euredjian), was filed
against 3Com and several of its present and former officers and directors in
United States District Court for the Northern District of California asserting
the same class period and factual allegations as the Hirsch and Kravitz actions.
The complaint alleges violations of the federal securities laws, specifically
Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and seeks
unspecified damages. The Company has not responded to the complaint. The Hirsch,
Kravitz and Euredjian actions were filed after Intel Corporation sharply
decreased prices on its Fast Ethernet network interface cards, which resulted in
3Com decreasing its prices on similar products. The Company believes it has
meritorious defenses to the claims in the Hirsch, Kravitz and Euredjian actions
and intends to contest the lawsuits vigorously. An unfavorable resolution of the
actions could have a material adverse effect on the business, results of
operations or financial condition of the Company.

Several securities actions have been filed against the Company and certain of
its current and former officers and directors following the Company's merger
with U.S. Robotics. In December 1997, a putative securities class action,
captioned Reiver v. 3Com Corporation, et al., Civil Action No. C-97-21083JW
(Reiver), was filed in the United States District Court for the Northern
District of California. The complaint alleges violations of the federal
securities laws, specifically Sections 10(b) and 20(a) of the Securities
Exchange Act of 1934, and seeks unspecified damages on behalf of a purported
class of purchasers of 3Com common stock during the period from May 19, 1997
through November 6, 1997. In December 1997 and January 1998, seven similar
shareholder class action lawsuits were filed in the United States District Court
for the Northern District of Illinois and the United States District Court for
the Northern District of California. The cases filed in the Northern District of
Illinois have been transferred to the Northern District of California, and the
cases have been consolidated in the Reiver action. A consolidated amended
complaint will be filed shortly.

On April 3, 1998, a complaint, captioned Florida State Board of Administration
and Teachers Retirement System of Louisiana v. 3Com Corporation, et al., Civil
Action No. C-98-1355 (Florida State Board), was filed in the United States
District Court for the Northern District of California. The complaint alleges
violations of the federal securities laws, violations of the Florida securities
laws, common law fraud and negligent misrepresentation based on factual
allegations similar to those asserted in the Reiver action. The Company has not
responded to the complaint. The Company believes it has meritorious defenses to
the claims in the Reiver and Florida State Board actions and intends to contest
the lawsuits vigorously. An unfavorable resolution of the actions could have a
material adverse effect on the business, results of operations or financial
condition of the Company.

In January 1998, two purported shareholder complaints relating to the Company's
June 1997 merger with U.S. Robotics, captioned Stanley Grossman v. 3Com
Corporation, et al., Civil Action No. CV771335, and Jason v. 3Com Corporation,
et al., Civil Action No. CV771713, were filed in California Superior Court,
Santa Clara County. The actions allege that 3Com, several of its officers and
directors, and several former U.S. Robotics officers violated Sections 11 and 15
of the Securities Act of 1933 by making alleged misrepresentations and omissions
in a May 8, 1997 registration statement. The complaints seek damages in an
unspecified amount on behalf of a purported class of persons who received the
Company's stock during the merger pursuant to the registration statement. The
Company has not responded to the complaints. The Company has filed a motion in
Delaware Chancery Court seeking an injunction preventing plaintiffs from
proceeding, on the basis that plaintiffs' claims are barred by a settlement in a
prior action. The Company believes it has meritorious defenses to the claims and
intends to contest the lawsuits vigorously. An unfavorable resolution of the
actions could have a material adverse effect on the business, results of
operations or financial condition of the Company.

58

In February 1998, a shareholder derivative action purportedly on behalf of the
Company, captioned, Wasserman v. Benhamou, et al., Civil Action No. 16200-NC,
was filed in Delaware Chancery Court. The complaint alleges that the Company's
directors breached their fiduciary duties to the Company by engaging in alleged
wrongful conduct from mid-1996 through November 1997, including the conduct
complained of in the securities litigation described above. The Company is named
solely as a nominal defendant, against whom the plaintiff seeks no recovery. The
Company and the individual defendants have filed a motion to dismiss the
complaint.

Intellectual Property Litigation

On April 28, 1997, Xerox Corporation filed suit against U.S. Robotics
Corporation and U.S. Robotics Access Corp. in the United States District Court
for the Western District of New York. The case is now entitled: Xerox
Corporation v. U.S. Robotics Corporation, U.S. Robotics Access Corp., Palm
Computing, Inc. and 3Com Corporation, Civil Action No. 97-CV-6182T. The
complaint alleges willful infringement of a United States patent relating to
computerized interpretation of handwriting. The complaint further prays for
unspecified damages and injunctive relief. Xerox has asserted that "Graffiti"
software and certain products of Palm Computing, Inc. infringe the patent. The
Company believes it has meritorious defenses to the claims and is contesting the
lawsuit vigorously. An unfavorable resolution of the action could have a
material adverse effect on the business, results of operations or financial
condition of the Company.

By an agreement effective February 27, 1998, the Company and Motorola, Inc.
settled the patent lawsuit pending between Motorola, Inc. and U.S. Robotics
Corporation, U.S. Robotics Access Corp. and U.S. Robotics Mobile Communications
Corp. in the United States District Court for the District of Massachusetts,
Civil Action No. 97-10339RCL. This case was dismissed on March 31, 1998. None of
the parties admitted fault. In connection with the settlement, the Company and
Motorola, Inc. entered into a cross-license of their respective patents relating
to high-speed analog modem technologies for implementation of international
standard data communication protocols. The terms of the settlement were not
material to the business, results of operations or financial condition of the
Company.

During February 1998 the Company and Livingston Enterprises, Inc. (Livingston)
agreed to settle the cases pending between Livingston and U.S. Robotics in the
United States District Court for the Northern District of California, Civil
Action Nos. C-97-3551CRB and C-97-3487CRB. These actions were dismissed on March
4, 1998. Neither party admitted fault in the settlement. The terms of the
settlement, which were not disclosed, were not material to the business, results
of operations, or financial condition of the Company.

Consumer Litigation

A putative consumer class action pending against the Company and U.S. Robotics
in the California Superior Court, Marin County, Bendall, et al. v. U.S. Robotics
Corporation, et al., Civil Action No. 170441 (Bendall), arising out of the
purchase of x2(TM) products and products upgradeable to x2, was coordinated with
a previously filed individual action in the California Superior Court, San
Francisco County, Intervention Inc. v. U.S. Robotics Corporation, Civil Action
No. 984352. Two putative consumer class action lawsuits pending against the
Company and U.S. Robotics in state court of Illinois arising out of the same
facts as those alleged in the California cases are stayed. Lippman, et al. v.
3Com, Civil Action No. 97 CH 09773, and Michaels, et al. v. U.S. Robotics Access
Corporation, et al., Civil Action No. 97 CH 14417. In June, 1998, the Company
filed a demurrer to the First Amended Complaint filed in Bendall. The Company
believes it has meritorious defenses to these lawsuits and intends to contest
the lawsuits vigorously. An unfavorable resolution of the actions could have a
material adverse effect on the business, results of operations or financial
condition of the Company.
