PART I

Subsequent to the end of fiscal year 1997, 3Com Corporation (referred to
herein as 3Com, Registrant or the Company) consummated a merger with U.S.
Robotics Corporation (U.S. Robotics) on June 12, 1997. See Note 17 of Notes to
the Consolidated Financial Statements. The following information set forth in
Part I of this Form 10-K regarding the Company's business reflects 3Com and U.S.
Robotics on a combined basis. The information contained in Parts II, III and IV
of this Form 10-K have not been restated to include the operating results of
U.S. Robotics, and does not represent the results of the combined company.

ITEM 1. Business

3Com Corporation was founded on June 4, 1979 and pioneered the networking
industry. Over the years, 3Com has evolved from a supplier of discrete
networking products to a broad-based supplier of local area network (LAN) and
wide area network (WAN) systems for the large enterprise, small business, home,
and service provider markets. Following its recent merger with U.S. Robotics,
the world's leading provider of modems and remote access products, 3Com offers
customers a broad range of data networking solutions that include routers, hubs,
remote access systems, switches, adapters, modems, connected organizers and
telephony products. 3Com's products are distributed and serviced worldwide
through 3Com and its partners: principally systems integrators, value-added
resellers (VARs), national resellers and dealers, distributors and original
equipment manufacturers (OEMs). Certain products, such as analog and digital
modems, adapters, connected organizers, and the Network Starter Kit, are also
sold through electronics catalogs and retailers.

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 to all parts of the world quickly and efficiently. The Company's
commitment to its customers goes beyond point-product excellence to making data
networks fundamentally easier to design, install, maintain and evolve. The
Company's objective is to make the network invisible to the individual end-user
as well as flexible and unconstrained for the network manager.

Since 1992, 3Com has augmented its internal growth by actively pursuing a
course of expanding its technologies and product offerings through strategic
acquisitions. From fiscal year 1993 through 1996, the Company acquired 10
companies that furthered its technological growth and market position, primarily
in enterprise networking. Of particular note, Synernetics, Inc., NiceCom, Ltd.,
Chipcom Corporation and AXON Networks, Inc. enhanced 3Com's product offering in
LAN and Asynchronous Transfer Mode (ATM) switching and remote network management
and monitoring (RMON2). The Company's activity in mergers and acquisitions is
consistent with the current trend of consolidation in the networking industry.
Such consolidation is expected to continue.

In the second quarter of fiscal 1997, the Company acquired OnStream
Networks, Inc. (OnStream), a leading provider of ATM and broadband WAN and
access products. OnStream's products are standards-based solutions that allow
customers to integrate traffic from data, video and voice networks, and adapt it
to ATM for transport over local and wide area ATM networks. The acquisition was

1



accounted for as a pooling-of-interests and was valued at approximately $245
million on the date the acquisition was announced.

In fiscal 1997, the Company introduced TranscendWare(TM) software, which
consists of comprehensive integrated software modules that are embedded in
3Com's broad line of networking systems and adapters. TranscendWare software is
an integral part of the Transcend(R) Networking framework and is used to manage
all aspects of the network. TranscendWare software, including Transcend
management applications, probes and embedded intelligence, delivers the
pervasive management needed for universal visibility and control.

Also in fiscal 1997, 3Com began shipping several new products, including
new high speed switching modules for the LANplex(R), CELLplex(R), and ONcore(R)
High-Function Switches, as well as SuperStack(R) II, the Company's
next-generation line of stackable systems and extensions to the OfficeConnect(R)
small office system. In the fourth quarter of fiscal 1997, the Company rebranded
its chassis switching product family which includes ONcore, CELLplex and LANplex
under the CoreBuilder(TM) brand to identify its industry leading High-Function
Switching platforms. The Company also extended its leadership position as the
number one global provider of Ethernet and Fast Ethernet adapters for desktop
PCs, servers and mobile computers, according to the March 1997 report of
International Data Corporation (IDC).

In the third quarter of fiscal 1997, the Company announced a definitive
agreement to merge with 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 transaction was closed in the first quarter of
fiscal 1998. Combining 3Com's capabilities and leadership position in the
enterprise and local area networking market with U.S. Robotics' capabilities and
leadership position in remote access and modem markets creates a networking
company with the ability to deliver integrated end-to-end LAN and WAN solutions
to the broadest set of customers in the industry. The acquisition was accounted
for as a pooling-of-interests and was valued at approximately $6.6 billion on
the date the acquisition was announced.

The Company believes that its principal competitive advantages lie in the
depth and breadth of its product lines, its ability to recognize and respond to
new trends in networking, its focus on making all aspects of networking easier
for network managers and users, and a strong yet flexible business
infrastructure. 3Com has strong brand recognition in modems and LAN workgroup
products, which it believes is transferable to other product and technology
areas and markets, such as core LAN switching, and remote office and personal
office internetworking platforms. Additionally, the Company believes its
low-cost manufacturing, worldwide presence, flexible distribution strategy, and
comprehensive service and support capabilities allow the Company to take
advantage of market trends that are extending the reach, scope and performance
of today's data networks.


INDUSTRY SEGMENT INFORMATION

3Com operates in one industry segment as described above.

2



PRODUCTS

3Com Corporation is committed to making the complexities of networks
invisible to end users and to making networks easier to design, install,
maintain and evolve. As the cornerstone of this commitment, 3Com has developed
Transcend Networking, a unique framework that adds end-to-end intelligence to
networks, giving them the power to satisfy burgeoning performance and
connectivity demands while keeping complexity and costs in check. Transcend
Networking takes a "three-vectored" approach to evolving networks. Each vector
consists of a host of innovative architectures, networking technologies,
platforms and specific products. The three vectors include:

o Scaling the Performance of the Network: Switching and desktop
connectivity solutions which provide migration to increased LAN
bandwidth/capacity by meeting the distinct requirements of the core and
boundary of the LAN;

o Extending the Reach of the Network: Wide area network routing and
remote access solutions which provide remote workgroups and individual
users with connectivity to resources on corporate backbones by meeting
the specific requirements of central and remote sites and of mobile and
home users;

o Managing the Growth of the Network: Networking products with embedded,
scaleable management features and innovative distributed network
monitoring, analysis and management solutions.

3Com TranscendWare software is an integral part of the Transcend Networking
framework. TranscendWare software enables centralized global network policies
that support key business objectives and the various communities of interest
within the network. TranscendWare software modules are grouped into three
functional categories: pervasive management, network control, and global policy.

Enterprise Systems

LAN switching platforms: 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. The development of custom application specific integrated
circuits (ASICs) for switching is central to the Company's switching strategy.
Virtually all of 3Com's internally developed switches are based on
custom-designed ASICs, which the Company believes will dramatically improve
performance and reliability while reducing costs. 3Com switches are available in
either chassis or stackable formats and are optimized to meet the specific needs
of the network core and its boundaries.

High-Function Switches: High-Function Switches are designed to meet the
requirements of the network core (backbone) for high density connectivity,
scaleable capacity, reliability and network control, and to meet the migration
needs of the customer. In a collapsed backbone environment, High-Function
Switches might act as high-performance, high capacity switches connecting
multiple boundary switches or hubs, or both, depending on the network design and
bandwidth needs of the different network segments.

o The CoreBuilder 5000 (formerly the ONcore Integrated System) switch is
an intelligent switching platform that delivers the reliability,
flexibility, and manageability required for enterprise networking now
and in the future. It supports Ethernet, Fast Ethernet, Fiber
Distributed Data Interface (FDDI), Token Ring, and ATM switching.

o The CoreBuilder 2500 and 6000 (formerly LANplex 2500 and 6000) provide
nonblocking performance while providing extensive software
functionality, including integrated routing and layer 3 switching. The
CoreBuilder 2500 offers high-speed links to FDDI, Fast Ethernet, or
ATM, and the CoreBuilder 6000 switch supports switched Ethernet, Token

Boundary switches: The Company's complete line of Boundary Switches
includes the award-winning SuperStack II switches and FastModules for the
CoreBuilder 5000 switch. Boundary switches are designed to meet the requirements
of the LAN boundary to reduce network latency at the desktop by providing
increased bandwidth, and to provide simple, plug-and-play connectivity. 3Com
boundary switches are available in either chassis or stackable format and
provide for Ethernet-to-Ethernet, Ethernet-to-Fast Ethernet, Ethernet-to-FDDI,
Ethernet-to-ATM, and Ethernet-to-Gigabit Ethernet connectivity.

Hubs: 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. 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 Ethernet,
Fast Ethernet, Token Ring and FDDI hubs in either stackable or chassis-based
configurations. The CoreBuilder 5000 system combines multitechnology
connectivity and workgroup and backbone switching in one manageable, reliable,
and secure package. SuperStack II Ethernet hubs offer superior flexibility with
security features, distributed RMON2 management, bridging, and resilient links
for LANs at a low cost of entry.

Small office systems: OfficeConnect products bring the enormous advantages
of networking to every office. The OfficeConnect system includes an
Ethernet/Fast Ethernet switch, Ethernet and Fast Ethernet hubs, print, fax and
CD-ROM servers, remote connectivity devices and branch office routers for the
small office. OfficeConnect systems combine simplicity of design and operation
with advanced functionality and outstanding speed.

Enterprise internetworking platforms: Internetworking devices link
multiprotocol LANs within the building/campus environment and provide WAN
connectivity to link multiple remote locations and provide access to the
Internet and other remote network resources. 3Com offers a variety of

4



internetworking solutions that extend the reach of the network, each tailored to
the specific needs of the application.

Backbone and remote office routers: For central sites needing
high-performance bridge/routing and a choice of Ethernet, Fast Ethernet, Token
Ring, FDDI, ATM and WAN connectivity, 3Com offers the high-density,
multiprotocol NETBuilder II(R) bridge/router. Available in a range of compatible
chassis with the ability to add additional processing power over time, the
NETBuilder II offers a high degree of scaleability to handle evolving LAN and
WAN integration requirements. The NETBuilder II also provides the central site
connection for NETBuilder(R) remote office solutions running Boundary Routing(R)

public voice networks, the AccessBuilder 9000 family of platforms affordably
supports all these services through its standards-based implementations and
interfaces.

Network management: Transcend network management software, an important
element of TranscendWare software, encompasses a full range of network
management applications and data collection methods and supports open platforms.
Its complementary hardware-based network monitoring products, software-based
applications, and network management agents deliver two great solutions: global,
networked application views to support customers' business goals; and detailed
information about device operations with port-level detail for precise technical
control of the network.

Carrier Systems

The Total Control(TM) Hub is a high-density remote access platform for
carrier and large enterprise markets. Total Control supports a wide variety of
dial-up applications at a low cost per port. Uses of the Total Control Hub range
from providing central site or Point of Presence (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. Total Control's flexible platform provides ISDN or analog dial
access. The communications modules can be configured and managed remotely
through the network management card, and the functionality and features of the
various communications modules can be upgraded through software downloads. For

PRODUCT DEVELOPMENT

The Company's product development efforts are focused exclusively on its
strategic products: enterprise systems, carrier systems, client access products
and connected organizers. The Company's ownership of core networking
technologies creates opportunities to leverage its engineering investments and
develop more integrated products for simpler, more innovative networking
solutions for customers. 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 lifecycles, reduce manufacturing costs and
increase functionality. In addition to the development of custom ASICs to
improve performance, increase reliability and reduce costs, the Company is
investing in the following areas: network management, Fast Ethernet (100 Mbps
Ethernet), Gigabit Ethernet (1000 Mbps Ethernet), ATM and other high speed
networking technologies, virtual local area network (VLAN) capabilities, ISDN
and other remote access technologies, enhanced connectivity in IBM environments,
and remote access for single and mobile users (including data-over-cable and
Asymmetric Digital Subscriber Line or ADSL technologies).

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

The industry in which 3Com competes is subject to rapid technological
developments, evolving industry standards, changes in customer requirements and
frequent new product introductions and enhancements. As a result, the Company's
success in part depends upon its ability, on a cost-effective and timely basis,
to continue to enhance its existing products and to develop and introduce new
products that take advantage of technological advances. The Company will
continue to make strategic acquisitions where appropriate. There can be no
assurance that 3Com will be able to successfully develop new products to address
new industry transmission standards and technological changes or to respond to
new product announcements by others or that such products will achieve market
acceptance.

For a more complete discussion regarding the Company's risks, see "Business
Environment and Risk Factors" included in Part II of this Form 10-K.


MARKETS AND CUSTOMERS

3Com's customers range from individual home PC users, to corporate
enterprises, to telecommunications companies and are represented among the
world's leading industries, including finance, health care, manufacturing,
government, education, and service organizations. The acquisition of OnStream
enhanced the Company's presence within the network service provider market,
while the merger with U.S. Robotics gives 3Com a broader reach and more leverage
across the four strategic markets that comprise the networking industry:
enterprises, carriers, small businesses and consumers.

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 partners 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. In
fiscal 1995, the Company began building a global end-user sales force to target
large enterprise accounts, and established a separate sales force to market to
telephone carriers and network service providers. Over the last 18 months, 3Com
has strengthened its global end-user sales force and service and support
organization by doubling the number of dedicated professionals.

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. The Company maintains
approximately 160 sales offices in 45 countries, with new offices opened in
fiscal 1997 in Eastern Europe, Latin America and the Asia Pacific region. The
Company primarily markets its products internationally through subsidiaries,
sales offices and relationships with local distributors in Europe, Canada, Asia
Pacific and Latin America (see Note 15 of the Notes to Consolidated Financial
Statements relating to geographic area information).

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 virtually around-the-clock
customer support regardless of geographic location. 3Com customer services
provide design, installation, maintenance, and delivery assistance across the
network. The Company supports its offerings internationally with 135 logistics
centers and 8 escalation centers communicating with customers in at least 17
languages. In addition to on-site

8



training, the Company also provides computer-based courses that allow customers
to learn networking technologies at their own pace in their own environments.


BACKLOG

3Com manufactures its products based upon its forecast of worldwide
customer demand and maintains inventories of 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 AND SUPPLIERS

3Com has manufacturing facilities in Santa Clara, California, and
Blanchardstown, Ireland. Purchasing, mechanical assembly, burn-in, testing,
final assembly, and quality assurance functions are performed at both 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 1996,
construction was completed on a 225,000 square foot office and manufacturing
facility at its headquarters in Santa Clara, and the Ireland facility was
expanded to 120,000 square feet. In fiscal 1997, the Company commenced
construction on 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 a 325,000 square foot office and manufacturing
facility in Singapore. The new Singapore manufacturing operations center, due to
open in the third quarter of fiscal 1998, will be 3Com's first production site
in the fast growing Asia Pacific region. The plant will be the first in
Singapore to manufacture networking equipment and will produce 3Com's full range
of high-volume products from network adapter cards and modems through
sophisticated enterprise systems.

Through the merger with U.S. Robotics, the Company also has manufacturing
facilities in Mount Prospect and Morton Grove, Illinois, and Salt Lake City,
Utah.

The Company is committed to being an environmentally conscious
manufacturer, and pioneered implementation of a chlorofluorocarbon (CFC)-free
semi-aqueous cleaning process at its California plant with DuPont and Corpane
Corporations. The same process is used at the Ireland facility, and 3Com met its
goal of being CFC-free by the end of calendar year 1993.

Components purchased by the Company are generally available from multiple
suppliers. However, certain components may be available from sole sources. The
inability of 3Com to obtain certain components could require the Company to
redesign or delay shipments of several of its data networking products. The
Company has sought to establish close relationships with sole-source suppliers
and/or to build up inventory of such components; however, there can be no
assurance that production would not be interrupted due to the unavailability of
components. The Company believes that its inventory levels of these components,
combined with finished components held by 3Com's suppliers, are adequate for its
currently forecasted needs.

COMPETITION

Networking is an expanding field within the information systems industry
encompassing both LAN and WAN technologies primarily for data networking, but
increasingly including voice and video traffic. 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, and ATM has changed the competitive landscape and
resulted in shorter product life cycles, and the creation of new standards and
competitors. 3Com's competitors typically compete in one or more segments of the
LAN/WAN sector of the data 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, acquisition and strategic partnering activity as many
of these companies seek to provide broader networking solutions.

Enterprise Systems: Competition in the network systems business, formerly
characterized by niche-based competitors focused on a single industry segment,
is shifting toward more 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 among a
small group of companies with broad product offerings. Principal competitors in
the network systems products market include Bay Networks, Cabletron and Cisco
Systems.

The market for high-speed, broadband networking products has grown rapidly,
driven by companies' implementation 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 and Cisco Systems, have introduced, or have announced their
intention to develop, network access switching products that are or will be
competitive with 3Com.

Carrier Systems: The market for remote access concentrators, primarily POP
connectivity equipment, has been characterized by a few networking vendors with
many complementary hardware products. Integrated remote access concentrators
like AccessBuilder and Total Control replace these multiple, single function
hardware products with a single software-defined platform capable of handling
both digital and analog signals. 3Com competes against various manufacturers of
the products mentioned above, including Ascend Communications, Bay Networks, and
Cisco Systems who manufacture integrated remote access concentrators.

Client Access Products: The market for network adapters is highly
competitive, with companies offering products that support a range of Ethernet,
Fast Ethernet, Token Ring and FDDI media. Traditional competitors in the adapter
market include Intel, IBM, Madge N.V., Olicom A/S, Standard Microsystems and
Xircom. However, as the trend from Ethernet to Fast Ethernet 10/100 Mbps

10



technology accelerates, the competitive landscape is changing to reflect
companies that have a strong position in Fast Ethernet, namely 3Com and Intel.

3Com and U.S. Robotics' primary competitors with respect to desktop and
mobile communications products include Best Data, Boca Research, Cardinal,
Diamond Multimedia, Hayes, Microcomputer Products, Motorola, Rockwell, TDK,
Xircom and Zoom Telephonies. The Company's near term success will depend
significantly on the market acceptance of its recently introduced x2 technology
developed by U.S. Robotics (pulse code modulation technology permitting
downloading of data over regular analog telephone lines at speeds up to 56
kilobits per second (Kbps)). The Company was the first to begin commercial
volume shipments of 56 Kbps technology products, named x2, in March 1997. 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 same basic 56 Kbps
technology and capabilities to market in the coming weeks and months. The
majority of these manufacturers have indicated their intention to implement this
high-speed technology with chipsets provided by Rockwell International
Corporation or Lucent Technologies, Inc. Industry standards will most likely be
determined in the first half of fiscal 1998. 3Com is committed to
standards-based networking and will migrate to the industry standard technology
via electronically downloadable upgrades.

Connected Organizers: The Company's primary competitors with respect to
connected organizers are Apple, Casio, Hewlett Packard, Psion and Sharp.


PATENTS, LICENSES 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 United States 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 77 utility patents and six design patents in the U.S., and has been
issued 14 foreign patents. After the merger with U.S. Robotics, the Company has
been issued a total of 114 utility patents and six design patents in the U.S.
and has been issued 24 foreign patents. Numerous other patent applications are
currently pending 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.

The Company has been granted licenses by others, including a fully paid,
perpetual, non-exclusive license to a patent held by Xerox covering a portion of
the Ethernet technology.

3Com has registered 72 trademarks in the United States and has registered
25 trademarks in one or more of 43 foreign countries. After the merger with U.S.
Robotics, the Company has registered 93

11



trademarks in the U. S. and 77 trademarks in one or more of 43 countries.
Numerous applications for registration of domestic and foreign trademarks are
currently pending.

Many of 3Com's products are designed to include software or other
intellectual property licensed from third parties. The Company actively seeks to
license software that promotes the compatibility of its products with industry
standards, including standard protocols and architectures. The loss of rights to
software or other intellectual property licensed from a third party and designed
into a particular product might disrupt or delay 3Com's distribution of that
product. While it may be necessary in the future to seek or renew licenses
relating to various aspects of its products, the Company believes that, based
upon past experience and standard industry practice, such licenses generally
could be obtained on commercially reasonable terms.


EMPLOYEES

As of May 31, 1997, 3Com had 7,109 full-time employees, of whom 1,584 were
employed in engineering, 2,853 in sales, marketing and customer service, 1,731
in manufacturing, and 941 in finance and administration. None of 3Com's
employees is represented by a labor organization and the Company considers its
employee relations to be excellent.

After the merger with U.S. Robotics, the Company had 13,639 full-time
employees, of whom 2,917 were employed in engineering, 4,353 in sales, marketing
and customer service, 4,426 in manufacturing, and 1,943 in finance and
administration.


ITEM 2. Properties

During the third quarter of fiscal 1997, the Company signed an operating
lease which combines and replaces three prior operating lease agreements on the
Company's existing headquarters site and on land adjacent to its existing
headquarters site. The combined lease includes approximately 870,000 square feet
of office and manufacturing space and two parking garages, and expires in
November 2001 with an option to extend the lease term for two successive periods
of five years each. The Company has an option to purchase the combined property
for $152.6 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 $152.6 million, subject to certain
provisions of the lease.

During the second quarter of fiscal 1997, the Company purchased a 14 acre
parcel of land and signed a two-year lease for an adjacent 58 acre parcel of
land, both of which are near its existing headquarters in Santa Clara. The lease
expires in November 1998 with an option to extend the lease term for two
successive periods of five years each. The Company has an option to purchase the

certain provisions of the lease.

The Company owns a facility comprised of three buildings near its Santa
Clara headquarters site. The 120,000 square foot facility, which was purchased
and occupied in the fourth quarter of fiscal 1996, is used primarily for its
Customer Services Operations.

12



The Company's primary distribution facility consists of 113,000 square feet
of warehouse and distribution space in Santa Clara. The space was occupied in
November 1995. The lease expires in December 2000, and has an option to renew
for an additional three year period.

3Com leases 163,000 square feet of office, manufacturing and distribution
space in Southborough, Massachusetts. The lease covers two locations, and
expires in July 1998 and January 1999, respectively.

3Com also leases a facility consisting of 100,000 square feet of office
space in Marlborough, Massachusetts. The lease expires in December 1999. During
the third quarter of fiscal 1997, 3Com signed a ground lease on an additional
128 acres in Marlborough for the consolidation and expansion of existing
operations.

In November 1996, 3Com exercised its option to purchase 72 acres, including
a 150,000 square foot office and manufacturing facility in Boxborough,
Massachusetts, which it had previously leased.

In May 1996, 3Com purchased a 10.5 acre site in Hemel-Hempstead,
Hertfordshire, including a 100,000 square foot facility for the consolidation
and expansion of the existing operations in Hemel-Hempstead. During the second
quarter of fiscal 1997, 3Com commenced construction of a second 100,000 square
foot research and development and customer service facility at the
Hemel-Hempstead campus, which is expected to be completed in the fourth quarter
of fiscal 1998.

In July 1992, 3Com Ireland, a wholly-owned subsidiary of 3Com, completed,
occupied and began operations in its Blanchardstown, Ireland manufacturing
facility. In January 1996 the facility was expanded to 120,000 square feet.
During the third quarter of fiscal 1997, 3Com Ireland purchased approximately 32
acres of land adjacent to this facility, and secured an option on an additional
9 acres. 3Com Ireland commenced construction of an additional 170,000 square
feet of manufacturing, research and development and office space, and expects to
commence occupancy in the second quarter of fiscal 1998.

During the second quarter of fiscal 1997, 3Com Technologies, a wholly-owned
subsidiary of the Company, signed a lease for seven acres of land in Changi,
Republic of Singapore. The Company began construction of 325,000 square feet of
office and manufacturing space in December 1996, and plans to occupy the
manufacturing facility in the third quarter of fiscal 1998.

3Com also leases various sales and service offices throughout the United
States, Canada, Europe, Australia, Latin America, and Asia. All of 3Com's
facilities are well maintained and are adequate to conduct 3Com's current
business.

The following is additional information regarding the properties acquired in the
merger with U.S. Robotics:

The Company owns two office facilities totaling 230,000 square feet and an
85,000 square foot manufacturing facility in Skokie, Illinois. The Company also
owns a 300,000 square foot manufacturing facility in Morton Grove, Illinois. The
Company purchased a 675,000 square foot facility for manufacturing, research and

13



which was previously leased. The Company also leases a 400,000 square foot
facility in Rolling Meadows, Illinois that it intends to use to accommodate
future growth in its business operations.

The Company owns a 185,000 square foot office facility and an adjacent
154,000 square foot manufacturing facility in Salt Lake City, Utah.


ITEM 3. Legal Proceedings

The Company is a party to lawsuits in the normal course of its business.
The Company and its counsel believe 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 patent 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.

On October 13, 1995, the Company acquired Chipcom, which had already been
named as a defendant in the litigation described below. Five complaints were
filed between May 30, 1995 and June 16, 1995 that alleged violations by the
defendants of Sections 10(b) and 20(a) of the Securities and Exchange Act of
1934, and sought unspecified damages. The cases were consolidated for pretrial
purposes pursuant to an order entered by the Court on June 15, 1995. The
consolidated action is entitled In re: Chipcom Securities Litigation, Civil
Action No. 95-111114-DPW. A Consolidated Complaint was filed on September 13,
1995, and an Amended Consolidated Complaint was filed on November 30, 1995.

The defendants' motion to dismiss the Amended Consolidated Complaint was
granted without leave to amend on May 1, 1996. The dismissal covers all five
cases. The plaintiffs appealed the order granting the dismissal. On October 1,
1996, the parties to these cases agreed upon what the Company considers to be
favorable financial terms for settlement of all five cases, which amount the
Company does not consider material to its operations, financial position, or
liquidity. Pursuant to the settlement which was approved by the District Court
on June 26, 1997, all claims of all persons which are related to the subject
matter of the Consolidated Complaint were settled and released.

On March 24, 1997, a putative shareholder class action lawsuit, entitled
Hirsch v. 3Com Corporation, et al., Civil Action No. CV764977, was filed against
the Company and certain of its officers and directors in the California Superior
Court, Santa Clara County. The complaint alleges, among other things, fraud,
negligent misrepresentation and violations of the California securities laws,
including that during the putative class period, sales of the Company's stock by
officers and directors of 3Com and acquisitions made with the Company's stock
occurred at inflated prices in light of undisclosed information. Specifically,
the complaint alleges violations of Sections 25400 and 25500 of the California
Corporations Code, Sections 1709 and 1710 of the California Civil Code, and
Sections 17200 et seq. and 17500 et seq. of the California Business and
Professions Code. The complaint, which covers a putative period of September 24,
1996 through February 10, 1997, does not specify the damages sought. Management
believes that the action is not meritorious and intends to vigorously contest
it. An adverse resolution of the action could have a material adverse effect on
the Company's results of operations and financial condition in the quarter in
which such adverse resolution occurs.

14



U.S. Robotics and certain of its directors were named as defendants in
eleven lawsuits relating to the merger between the Company and U.S. Robotics
brought in the Delaware Chancery Court (In re: U.S. Robotics Corporation
Shareholder's Litigation, Delaware Chancery Court Consolidated Civil Action No.
15580). See Note 17 of Notes to the Consolidated Financial Statements. The
Company has been named as a defendant in nine of these actions. The lawsuits,
which purport to be stockholder class actions brought on behalf of all U.S.
Robotics stockholders, allege, inter alia, that the directors of U.S. Robotics
have breached their fiduciary duties by approving the Merger Agreement, and that
the Company aided and abetted this alleged breach of duty. An agreement in
principle to settle this litigation has been reached with plaintiffs' counsel on
what the Company considers to be favorable financial terms, which amount the
Company does not consider to be material to its operations, financial position,
or liquidity. This settlement is not yet final and will not be final until
approved by the Court after a hearing.

On February 13, 1997, Motorola, Inc. filed suit against U.S. Robotics in
the United States District Court for the District of Massachusetts (Motorola,
Inc. v. U.S. Robotics Corporation, et al., Civil Action No. 97-10339RCL),
claiming infringement of eight United States patents. The complaint alleges
willful infringement and prays for unspecified damages and injunctive relief. In
a separate statement announcing the filing of the lawsuit published on
PRNewswire on the same date, Motorola alleged that the patents at issue cover
"technologies essential to the International Telecommunications Union (ITU) V.34
modem standard." In the same statement, a Motorola officer is quoted as saying
that Motorola is "committed" to making its technology incorporated in standards
available on a "fair, reasonable and non-discriminatory basis." U.S. Robotics
has filed an answer to Motorola's claims setting forth its defenses and
asserting counterclaims which allege infringement of a U.S. Robotics patent,
violation of antitrust laws, promissory estoppel and unfair competition.
Although the Company believes it has meritorious defenses to Motorola's claims
and intends to contest this lawsuit vigorously, an adverse outcome of such
litigation could have a material adverse effect on the business, results of
operations or financial condition of the Company.

On April 26, 1997, Xerox Corporation filed suit against U.S. Robotics in
the United States District Court for the Western District of New York (Xerox
Corporation v. U.S. Robotics Corporation and U.S. Robotics Access Corp., No.
97-CV-6182T), claiming infringement of one United States Patent. The complaint
alleges willful infringement and prays for unspecified damages and injunctive
relief. In a press release dated April 30, 1997, Xerox alleged that its patent,
issued January 21, 1997, "covers the use and recognition of handwritten text
using an alphabet system designed especially for reliable recognition in pen
computers," and that U.S. Robotics' PalmPilot hand-held computer and "Graffiti"
software infringe the Xerox patent. The Company believes it has meritorious
defenses to Xerox's claims and intends to contest the lawsuit vigorously. An
adverse resolution of the action could have a material adverse effect on the
Company's results of operations and financial condition in the quarter in which
such adverse resolution occurs.

On April 21, 1997, U.S. Robotics and three of its customers, Best Buy Co.,
Inc., Egghead, Inc. and Fry's Electronics, Inc., were sued in a purported
consumer class action filed in Superior Court in Marin County, California
(Bendall et al v. U.S. Robotics Corporation et al, No. 170441). The named
plaintiffs are residents of the states of Alabama, California, Tennessee and
Washington and they purport to represent various classes of persons who have
purchased or otherwise acquired U.S. Robotics' new x2 products and products
upgradeable to x2. Damages, including punitive damages, and other relief are
sought under the California Consumer Legal Remedies Act and the California
Song-Beverly Consumer Warranty Act, and under various common law theories,
including breach of contract, fraud and deceit,

15



negligent misrepresentation, breach of implied warranty and unjust enrichment.
The Company believes it has meritorious defenses to this lawsuit and intends to
contest the lawsuit vigorously. An adverse resolution of the action could have a
material adverse effect on the Company's results of operations and financial
condition in the quarter in which such adverse resolution occurs.

Another lawsuit, purporting to be "For the interests of the General Public"
was filed against U.S. Robotics in the same court on March 13, 1997 (Levy v.
U.S. Robotics Corporation, No. 170968). This action alleges that U.S. Robotics'
promotion and advertising of x2 products constituted unfair competition and
deceptive, untrue and misleading advertising in violation of the California
Business and Professional Code, and seeks injunctive relief, including
"restitution of all revenues" and an award of attorney fees. Additionally, a
purported public interest plaintiff sued U.S. Robotics on January 29, 1997 in
California Superior Court in San Francisco (Intervention Inc. v. U.S. Robotics
Corporation, Case No. 984352) under the same statute, alleging various
misrepresentations in connection with the promotion and advertising of U.S.
Robotics' x2 products, and seeking injunctive and other relief, including
attorney's fees. The Company believes it has meritorious defenses to this
lawsuit and intends to contest the lawsuit vigorously. An adverse resolution of
the action could have a material adverse effect on the Company's results of
operations and financial condition in the quarter in which such adverse
resolution occurs.

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.

SUBSEQUENT EVENT

On June 12, 1997, 3Com Corporation ("the Company") consummated a 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. The Company issued approximately 158 million
shares of its common stock in exchange for all outstanding common stock of U.S.
Robotics and assumed and exchanged all options to purchase U.S. Robotics' stock
for options to purchase approximately 31 million shares of the Company's common
stock. The transaction was accounted for as a pooling-of-interests. U.S.
Robotics' sales and net income for the twelve months ended March 30, 1997 were
$2,493.8 million and $237.3 million, respectively. As of March 30, 1997, U.S.
Robotics' assets and stockholder's equity totaled $1,407.3 million and $863.5
million, respectively.

The Company anticipates that as a result of the merger, the combined
company will incur restructuring charges and direct transaction costs relating
to the business combination, estimated to be between $325 million and $375
million. These non-recurring costs will be charged to operations in the first
quarter of fiscal 1998. See Note 17 of Notes to Consolidated Financial
Statements.

The following information has not been restated to include the operating
results of U.S. Robotics, and does not represent results of the combined
company. The following discussion, including Business Environment and Risk
Factors, represents 3Com on a standalone basis. For information regarding 3Com
and U.S. Robotics on a combined basis, refer to the Joint Proxy
Statement/Prospectus dated May 8, 1997. For historical information regarding
U.S. Robotics on a standalone basis, refer to its quarterly report on Form 10-Q
for the quarter ended March 30, 1997, and its report on Form 10-K for the year
ended September 29, 1996.


BUSINESS COMBINATIONS

On October 31, 1996, the Company acquired OnStream Networks, Inc.
(OnStream), a provider of Asynchronous Transfer Mode (ATM) and broadband wide
area network (WAN) and access products. The Company issued approximately 3.3
million shares of its common stock in exchange for all the outstanding stock of
OnStream, and 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. 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.

To enhance its product offerings and accelerate its time-to-market in new
technologies, the Company completed several business combinations in previous
years. In fiscal 1996, the Company acquired Chipcom Corporation (Chipcom), a
provider of computer networking multi-function platforms,

24



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. In fiscal 1995, the
Company acquired Sonix Communications, Ltd. (Sonix), a provider of ISDN
connectivity solutions in the United Kingdom, and NiceCom, Ltd. (NiceCom), an
innovator of ATM technology, and Chipcom acquired Artel Communications
Corporation (Artel), a provider of high-performance communication systems for
the internetworking and video distribution markets and DSI ExpressNetworks, Inc.
(DSI), a developer of intelligent hubs and internetworking products.

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

Comparison of fiscal years ended May 31, 1997 and 1996

Fiscal 1997 sales increased 35 percent to $3.1 billion from $2.3 billion in
fiscal 1996. The Company believes that the increase in fiscal 1997 sales is due
to several factors, including growth in the data networking market as the
Internet, corporate intranets, client server applications and remote access
services stimulate customers to migrate from shared to switched media and to
larger bandwidth and higher speed technologies, such as Fast Ethernet and ATM,
to support data, voice and video multimedia traffic. The

25



Company also believes that the strength of the Company's product offerings at
the edge of the network, including workgroup switches and hubs, the impact of a
strong new product cycle in systems and adapter products, the continuous
expansion of 3Com's product offerings, and the ability to deliver complete data
networking solutions for different connectivity environments contributed to the
increase in sales over the prior year.

Although the Company experienced relatively strong year over year growth,
the Company's growth rate has moderated in the last half of fiscal 1997. The
Company believes this moderation reflects recent slowed growth in the networking
industry, in combination with increased competitive pricing pressures in the
form of aggressive price reductions and product promotions for certain products,
particularly network adapters, stackable hubs, and workgroup switches. The
Company also experienced declines in its router business, which the Company
believes are primarily due to delays in certain large enterprise customer
orders. The Company believes that the industry is transitioning from shared to
switched networks, from lower to higher-speed technologies, and to more
volume-based pricing and distribution, and that these transitions may be
adversely affecting customer purchasing decisions. Competitive pricing pressures
in adapters, stackable hubs and workgroup switches have resulted in average
selling prices declining more rapidly than in the past. The Company believes
such pricing trends, as well as the uncertainties created by the trend towards
switched networks, may adversely affect the industry's and the Company's growth
rates in the coming quarters, and consequently, the Company's historical growth
rates should not be relied upon as an indication of its future performance. See
Business Environment and Risk Factors discussed below.

Sales of network systems products (i.e., internetworking platforms, remote
access servers, hubs, switching products and customer service) increased 30
percent from fiscal 1996, and represented 57 and 59 percent of total sales in
fiscal years 1997 and 1996, respectively. The increase in fiscal 1997 network
systems product sales was led primarily by the SuperStack(R) II workgroup
switching family, the CELLplex(R) ATM High-Function switching family, SuperStack
II Ethernet and Fast Ethernet hubs, and the ONcore(R) intelligent switching
system. The increase in network systems products was partially offset by
declines in sales of the AccessBuilder(R) 8000 access concentrator. The Company
experienced a significant increase in unit volume in workgroup switching
products and Ethernet and Fast Ethernet stackable hubs, partially offset by a
decline in average selling prices resulting from increased competition and
pricing pressures. Customer service revenue is included in network systems
products (previously this revenue was classified as other products), and
accordingly, all sales composition and growth percentages reflect this
reclassification.

Sales of network adapters increased 45 percent from fiscal 1996, and
represented 42 and 40 percent of total sales in fiscal years 1997 and 1996,
respectively. The increase in fiscal 1997 network adapter sales represented a
significant increase in unit volume, partially offset by a decline in average
selling prices. The increase in sales was led primarily by the Fast EtherLink(R)
PCI adapters, the EtherLink PC Card adapters, and the EtherLink III family of
network adapters. During the third quarter of fiscal 1997, a major competitor
reduced its average selling prices on Fast Ethernet adapter products by
approximately 40 percent. The Company immediately responded with similar price
cuts. As a result, the Company has recently experienced an accelerated
transition from 10 Mb Ethernet to Fast Ethernet adapters.

Sales of other products represented one percent of total sales in fiscal
1997 and 1996, and are not significant to the Company's operations.

Sales outside of the United States increased 36 percent from the same
period a year ago, and comprised 53 percent of total sales in fiscal years 1997
and 1996. International sales increased in all major geographic

26



regions, with especially strong growth in the Asia Pacific and Latin America
regions, however, in the latter half of fiscal 1997, sales in certain European
countries moderated. The Company believes that the growth in international sales
is due primarily to the Company's continued global expansion through the opening
of new sales offices, and the expansion of its worldwide field sales, service
and support programs. Sales in the U.S. increased 34 percent compared to fiscal
1996. Substantially all of the Company's sales are denominated in U.S. Dollars.
The Company's operations were not significantly impacted by fluctuations in
foreign currency exchange rates in fiscal years 1997, 1996 and 1995.

Gross margin as a percentage of sales was 53.9 percent in fiscal 1997,
compared to 52.9 percent in fiscal 1996. The 1.0 percentage point increase in
gross margin in fiscal 1997 primarily reflected an improved shipment mix of
higher margin workgroup switching and hub products and lower margin network
access concentrators, and lower product material costs of certain adapter
products. Factors causing the increase in gross margin were partially offset by
a higher mix of certain lower margin adapter products. During the third quarter
of fiscal 1997, the Company reduced its average selling prices on Fast Ethernet
adapter products by approximately 40 percent in response to the aforementioned
increased competition, thus causing a recent decline in gross margins, which was
not completely reflected in fiscal 1997. The Company believes that the
competitive pricing pressures in the Fast Ethernet adapters, stackable hub and
workgroup switching products may well result in future declines in gross
margins.

Total operating expenses in fiscal 1997 were $1,131.4 million, compared to
$928.6 million in fiscal 1996. Excluding an acquisition-related charge of $6.6
million related to the acquisition of OnStream (see Note 12 of Notes to
Consolidated Financial Statements), total operating expenses in fiscal 1997
would have been $1,124.8 million, or 35.7 percent of sales. Excluding an
acquisition-related charge of $69.0 million related to the acquisition of
Chipcom, a charge of $52.4 million for purchased in-process technology
associated with the acquisition of AXON and a charge of approximately $1.0
million for a settlement of litigation, total operating expenses in fiscal 1996
would have been $806.3 million, or 34.6 percent of sales.

Sales and marketing expenses in fiscal 1997 increased $183.8 million or 39
percent from fiscal 1996. The increase in such expenses reflected increased
costs associated with the 35 percent increase in sales, a 52 percent
year-over-year increase in sales and marketing personnel, as the Company
continued to invest in the expansion of its direct sales force, and an increase
in the Company's customer support programs and marketing promotions. As a
percentage of sales, sales and marketing expenses were 21.0 percent in fiscal
1997, compared to 20.5 percent in fiscal 1996.

Research and development expenses in fiscal 1997 increased $102.2 million
or 44 percent from the prior year. As a percentage of sales, research and
development expenses increased to 10.7 percent in fiscal 1997, from 10.0 percent
in fiscal 1996. The increase in research and development expenses was primarily
attributable to the cost of developing 3Com's new products and technologies,
primarily switching, network management and value-added software, and the
Company's expansion into new technologies and markets. 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. As of May 31, 1997, most of the
in-process research and development projects acquired in connection with the
Company's business acquisitions have been completed. The Company estimates that
the remaining costs in connection with the completion of outstanding acquired
research and development projects are not significant, and are primarily made up
of labor costs for design, prototype development and testing. The increase in
research and development expenses is consistent with the Company's continued
commitment to develop and introduce high quality, innovative products.

27



General and administrative expenses in fiscal 1997 increased $32.6 million
or 33 percent from the prior year. The increase in general and administrative
expenses reflects the worldwide expansion of the Company's infrastructure
through internal growth and acquisitions, including an increase in personnel of
35 percent compared to the prior year, increased investment in the Company's
worldwide information systems and costs associated with the Company's expansion
into the Asia Pacific region. As a percentage of sales, such expenses decreased
to 4.1 percent in fiscal 1997, compared to 4.2 percent in fiscal 1996.

Other income (net) was $20.9 million in fiscal 1997, compared to $6.8
million in fiscal 1996. These amounts consist primarily of interest income,
which increased $12.8 million in fiscal 1997, due primarily to larger cash and
investment balances.

The Company's effective income tax rate was 36.0 percent in fiscal 1997.
Excluding the merger costs associated with the OnStream merger which were not
tax deductible, the effective tax rate for fiscal 1997 would have been 35.6
percent. The Company's effective income tax rate was 42.3 percent in fiscal
1996. Excluding the charge for purchased in-process technology associated with
the acquisition of AXON, which was not tax deductible, and the nondeductible
portion of the merger costs associated with the Chipcom acquisition, the
effective tax rate for fiscal 1996 would have been 35.0 percent.

Net income for fiscal 1997 was $374.0 million, or $2.01 per share, compared
to net income of $177.9 million, or $1.00 per share for fiscal 1996. Excluding
the aforementioned acquisition-related charge of $6.6 million, the Company would
have realized net income of $380.6 million, or $2.05 per share for fiscal 1997.
Net income for fiscal 1996 included the aforementioned acquisition-related
charge of $69.0 million, the $52.4 million charge for purchased in-process
technology and the $1.0 million charge for a litigation settlement. Excluding
these charges, the Company would have realized net income of $280.0 million, or
$1.58 per share for fiscal 1996.

Comparison of fiscal years ended May 31, 1996 and 1995

Fiscal 1996 sales increased 46 percent to $2.3 billion from $1.6 billion in
fiscal 1995. The Company believes that the increase in fiscal 1996 sales was due
to several factors, including continued strength in the data networking market
as customers migrate to new technologies such as LAN switching and Fast
Ethernet, increases in worldwide personal computer sales, rapid growth in sales
outside the U.S., and the continuous expansion of 3Com's product offerings and
its ability to deliver complete data networking solutions for different
connectivity environments.

Sales of network systems products increased 56 percent from fiscal 1995,
and represented 59 and 55 percent of total sales in fiscal years 1996 and 1995,
respectively. The increase in fiscal 1996 network systems product sales was led
primarily by the LinkBuilder FMS II stackable hub, the LANplex and LinkSwitch
families of switching products, the AccessBuilder 8000 integrated network access
system and the ONcore intelligent switching system. The increase in network
systems products was partially offset by declines in sales of certain product
lines acquired from Chipcom.

Sales of network adapters increased 35 percent from fiscal 1995, and
represented 40 and 43 percent of total sales in fiscal years 1996 and 1995,
respectively. The increase in fiscal 1996 network adapter sales represented a
significant increase in unit volume, primarily the result of increased sales of
the EtherLink III network adapter and the EtherLink PC Card adapter and the
introduction of the Fast EtherLink PCI adapter.

28



The trend toward decreasing average selling prices in all adapter products
continued in fiscal 1996, but was mostly offset by the increased mix of Fast
Ethernet and PC Card products, which carry higher average selling prices.

Sales of other products represented one percent of total sales in fiscal
1996 and two percent of total sales in fiscal 1995, and were not significant to
the Company's operations.

Sales outside of the United States increased 48 percent from the same
period a year ago, and comprised 53 percent of total sales in fiscal 1996,
compared to 52 percent in fiscal 1995. The Company believes that the increase in
international sales was a result of strong growth in the Asia Pacific region,
the breadth of the Company's product offerings, its 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. Sales in the U.S.
increased 44 percent compared to fiscal 1995.

Gross margin as a percentage of sales was 52.9 percent in fiscal 1996,
compared to 53.7 percent in fiscal 1995. The 0.8 percentage point reduction in
gross margin in fiscal 1996 resulted primarily from a higher mix of certain
lower margin adapter and network access system products and increased provisions
for obsolete and excess inventory. Factors causing the decline in gross margin
were partially offset by a favorable shipment mix toward the Company's switching
products and reductions in adapter product material costs.

Total operating expenses in fiscal 1996 were $928.6 million, compared to
$630.9 million in fiscal 1995. Excluding the acquisition-related charge of $69.0
million related to the acquisition of Chipcom, the charge of $52.4 million for
purchased in-process technology associated with the acquisition of AXON, and a
charge of approximately $1.0 million for a settlement of litigation (see Note 12
of Notes to Consolidated Financial Statements), total operating expenses in
fiscal 1996 would have been $806.3 million, or 34.6 percent of sales. Excluding
a charge of $68.7 million for purchased in-process technology associated with
the acquisitions of NiceCom and DSI, a non-recurring charge of $10.1 million,
which consisted of approximately $11.2 million in merger transaction costs
associated with the acquisitions of Artel, Primary Access and Sonix, and a
credit of $1.1 million for the reduction in accrued costs relating to the fiscal
1991 restructuring, total operating expenses in fiscal 1995 would have been
$552.1 million, or 34.6 percent of sales.

Sales and marketing expenses in fiscal 1996 increased $156.5 million or 49
percent from fiscal 1995. The increase in such expenses reflected increased
selling costs related to the 46 percent increase in sales, higher costs
associated with marketing promotions and sales support programs, and a
year-over-year increase in sales and marketing personnel of 35 percent. The
Company believes the increase in sales and marketing expenses was also a direct
result of the Chipcom acquisition. As a percentage of sales, sales and marketing
expenses were 20.5 percent in fiscal 1996, compared to 20.0 percent in fiscal
1995.

Research and development expenses in fiscal 1996 increased $66.8 million or
40 percent from the prior year. The increase in research and development
expenses was primarily attributable to the cost of developing new products,
including the Company's expansion into new technologies and markets. Full time
research and development personnel increased 27 percent in fiscal 1996. As a
percentage of sales, research and development expenses were 10.0 percent in
fiscal 1996, compared to 10.5 percent in fiscal 1995.

General and administrative expenses in fiscal 1996 increased $30.9 million
or 47 percent from the prior year. The increase in general and administrative
expenses reflected the worldwide expansion of the Company's infrastructure
through internal growth and acquisitions. As a percentage of sales, such
expenses remained flat at 4.2 percent in fiscal 1996 and 1995.

Other income (net) was $6.8 million in fiscal 1996, compared to $4.9
million in fiscal 1995. The fiscal 1996 increase was primarily caused by
interest income, which increased $9.3 million in fiscal 1996, due to larger cash
and investment balances and higher interest rates. Partially offsetting this
increase in other income was the issuance of $110.0 million of convertible
subordinated notes in the second quarter of fiscal 1995, which in addition to
increasing cash balances, contributed to an increase in interest expense of $5.5
million in fiscal 1996.

The Company's effective income tax rate was 42.3 percent in fiscal 1996.
Excluding the purchased in-process technology charge associated with the
acquisition of AXON, which was not tax deductible, and the nondeductible portion
of the merger costs associated with the Chipcom acquisition, the effective tax
rate would have been 35.0 percent. The Company's effective income tax rate was
36.9 percent in fiscal 1995. Excluding the charges for purchased in-process
technology associated with the acquisitions of NiceCom and DSI and the merger
costs associated with the Sonix and Primary Access acquisitions, which were not
tax deductible, the effective tax rate would have been 36.0 percent.

Net income for fiscal 1996 was $177.9 million, or $1.00 per share, compared
to net income of $144.6 million, or $0.84 per share for fiscal 1995. Net income
for fiscal 1996 included the aforementioned acquisition-related charge of $69.0
million, the $52.4 million charge for purchased in-process technology and the
$1.0 million charge for a litigation settlement. Excluding these charges, the
Company would have realized net income of $280.0 million, or $1.58 per share for
fiscal 1996. Net income for fiscal 1995 included the aforementioned $68.7
million charge for purchased in-process technology, the $11.2 million charge for
merger costs and the $1.1 million credit for the reduction in the restructuring
reserve. Excluding these charges and credits, the Company would have realized
net income of $195.5 million, or $1.14 per share for fiscal 1995.


BUSINESS ENVIRONMENT AND RISK FACTORS

This report contains certain forward looking statements, including
statements regarding future trends in sales, gross margin, expense and liquidity
levels, and the amount of the expected non-recurring charge to operations for
the U.S. Robotics merger. Actual results could vary materially based upon a
number of factors, including but not limited to those set forth below. The
Company's future operating results may be affected by various trends and factors
which the Company must successfully manage in order to achieve favorable
operating results. In addition, there are trends and factors beyond the
Company's control which affect its operations. In accordance with the provisions
of the Private Securities Litigation Reform Act of 1995, the cautionary
statements set forth below identify important factors that could cause actual
results to differ materially from those in any forward-looking statements which
may be contained in this report. Such trends and factors include, but are not
limited to, adverse changes in general economic conditions or conditions in the
specific markets for the Company's products, governmental regulation or
intervention affecting communications or data networking, fluctuations in
foreign exchange rates, and other factors, including those listed below.

The Company participates in a highly volatile and rapidly growing industry
which is characterized by vigorous competition for market share and rapid
technological development carried out amidst uncertainty over adoption of
industry standards and protection of proprietary intellectual property rights.
This has in the past resulted and could result in aggressive pricing practices,
such as those recently adopted by a competitor in the adapter market, and
growing competition, both from start-up companies and from well-capitalized
computer systems and communications companies. The Company's ability to compete
in this environment depends upon a number of competitive and market factors, and
is subject to the risks set forth in this report and other factors.

The market for the Company's products is intensely competitive and
characterized by rapidly changing technology. The Company's success depends, in
substantial part, on the timely and successful introduction of new products. An
unexpected change in one or more of the technologies affecting data networking,
or in market demand for products based on a particular technology, such as the
recent change from shared to switched networks and the slowdown in sales of
certain products for the edge of the network, could have a material adverse
effect on the Company's operating results if the Company does not respond timely
and effectively to such changes. The Company is engaged in research and
development activities in certain emerging LAN and WAN high-speed technologies,
such as ATM, ISDN, DSL, Fast Ethernet, Gigabit Ethernet and data-over-cable. As
the industry standardizes on high-speed technologies, there can be no assurance
that the Company will be able to respond promptly and cost-effectively to
compete in the marketplace. In addition, if the PC industry migrates toward
standardizing the integration of network interface capabilities on the PC
motherboard, and if the Company does not manage its business to cost-effectively
transition toward this technology, it could have an adverse impact on the
Company.

Although long-term annual growth rates for the networking industry have
recently been in the 30 to 50 percent range, there can be no assurance that this
industry growth rate will continue at the same level, or that the Company's
results in any particular quarter will fall within that range. In particular,
based on recent softening of demand for networking products and competitive
pricing pressures, the Company anticipates that its results may fall below those
levels in the coming quarters.

The Company's customers historically request fulfillment of orders in a
short period of time, resulting in a minimal backlog. Quarterly sales and
results of operations generally depend on the volume and timing of orders, and
the ability to fulfill them within the quarter. As a result, the lack of backlog
provides limited visibility to the Company's future sales trends.

Recruiting and retaining skilled personnel, especially in certain locations
in which the Company operates, is highly competitive. Unless the Company can
successfully recruit and retain such personnel, the Company's ability to achieve
continued growth in sales and earnings may be adversely affected.

The Company operates in an industry in which the ability to compete is
dependent on the development or acquisition of proprietary technology, which
must be protected both to preserve the benefits of exclusive use of the
Company's own technology, and enable the Company to license technology from
other parties on acceptable terms. The Company attempts to protect its
intellectual
