PART I

ITEM 1. Business

GENERAL

3Com Corporation (3Com) was founded on June 4, 1979. A pioneer in the computer networking industry, we believe we are the only networking company that offers a unique blend of practical and innovative technology that provides our channel partners and customers with high-value, practical-to-use solutions. Our competitive strengths include our strong balance sheet, industry-leading intellectual property portfolio, distributor and customer relationships, and brand identity. We believe that the leading tier one

2

networking company of the future will be the one that offers innovative, feature-rich products and solutions that excel at low cost of acquisition and ownership. Further, if that company also maintains the lowest cost structure and best asset velocity, it can generate superior financial returns. We intend to be that company.

On June 6, 2002, we announced that after substantially improving the competitiveness of Business Connectivity Company (BCC) and Business Networks Company (BNC), 3Com would merge BCC into BNC to drive further efficiencies in each business while leveraging growth opportunities. Since July 1, 2002, we have structured our operations around two businesses. BNC focuses on the enterprise market and now consists of three divisions: Local Area Network (LAN) Infrastructure Division, Personal Systems Division, and Connectivity Division. The Connectivity Division of BNC focuses on basic client connectivity products and solutions. The Network Jack product is now managed under the Personal Systems Division of BNC, and other offerings formerly managed under Business Connectivity Company in fiscal 2002 are now managed under the LAN Infrastructure Division of BNC. CommWorks Corporation continues to focus on the telecommunications service provider market.

In fiscal 2003, we will operate our company and report our financial results in three ongoing segments:

1)

Enterprise Networking Segment, consisting of the LAN Infrastructure Division and Personal Systems Division of Business Networks Company,

2)

Connectivity Segment, consisting of the Connectivity Division of Business Networks Company, and

3)

CommWorks Segment.

Each of these segments has a unique capital investment and business model tuned for the dynamics of its target market. Additionally, our exited products will continue to be presented as a separate segment.

In fiscal 2002, we operated three ongoing segments: Business Networks Company, Business Connectivity Company, and CommWorks Corporation. The discussion of industry segments below is presented as we operated our company and reported our financial results in fiscal 2002.

INDUSTRY SEGMENTS

Business Networks Company

Building on 3Com's historical success in the networking infrastructure market, 3Com's Business Networks Company is a leader in delivering innovative networking products and solutions that are feature-rich so they can support the increasingly complex and demanding application environments in today's businesses, while remaining easy to install, use, and operate, and affordable to own.

BNC provides a broad range of innovative networking solutions, which enable customers to manage business-critical information, enhance the productivity of employees, and improve the effectiveness of business relationships at an affordable price. By enriching the user experience through high performance and innovative technology, BNC provides practical solutions to meet the demanding real-world needs of customers, while at the same time allowing them to run their businesses rather than spend time focusing on getting the technology to work.

Industry Background:

During the 1980s and 1990s, 3Com became a worldwide leader building enterprise networks and the equipment that connects computers to networks. In 1981, International Business Machines Corp. (IBM) introduced the personal computer (PC) and in 1983, 3Com introduced the first network interface card (NIC) that connected the IBM PC into Ethernet networks. At first, computers were connected together in LANs, so people in workgroups could more easily share information, such as spreadsheets, and resources, such as printers and servers. Then, network applications—email, for example—were developed, and these applications ignited the demand to connect workgroups together into enterprise-wide networks. Outside of

3

the enterprise, individuals connected over wide area networks (WANs) and started forming on-line communities through services such as CompuServe and America Online. The second half of the 1990s saw the build-out of the Internet, and by the end of that decade the number of people and businesses connected to networks had all scaled far beyond what anyone ever imagined.

Based on current economic trends, most organizations are under pressure to scale back investment in capital projects, and even more so with regard to operating expenses. They are also being forced to look at all possible ways to increase shareholder value and show return on invested capital. From a technology perspective, this is causing investments in networking and desktop equipment to be questioned more than ever before. Information technology (IT) managers must be able to justify any new investment in infrastructure.

From a customer perspective, most organizations are attempting to get closer to their customers by implementing customer relationship management (CRM) applications. With the growth of supply chain management, businesses must be able to support a diverse user community that includes suppliers, partners and customers. Information and knowledge management is yet another key part of understanding the customer, as databases are consolidated and information exchanged. All of this is part of the larger drive to increase staff efficiency and productivity. To realize the full benefits of this, an organization must integrate their CRM system together with their manufacturing system more effectively.

Finally, network managers are increasingly concerned about the integrity of corporate data and how this data, their users, and devices are secured. This problem is magnified when users are on the move and outside the controlled corporate environment. More people are accepting the Internet as a business tool, which has led to an explosion in e-business and the general growth of Internet-based transactions in the commercial workplace.

Markets and Customers:

BNC develops networking solutions for enterprise and small business customers worldwide. These solutions are sold through the company's worldwide channel of over 55,000 value-added resellers, system integrators and telecommunications service providers.

BNC acknowledges that networking needs vary by size of business, from industry to industry, and across the globe. BNC therefore develops a full product line of networking solutions to fit the demanding business needs of customers from the very small to the very large. BNC does this by delivering rich functionality, high performance, reliability, and security in a way that is easy to install, configure, manage, and use, and is well-suited for the target customer environment. Importantly, BNC delivers these solutions in a way that is affordable to own and operate.

BNC has one of the largest installed bases of mid-sized and large enterprise customers in the industry and has sold tens of millions of switching ports not only to commercial customers but also to many in healthcare, government and education. BNC delivers the performance, features and flexibility demanded by these customers to meet their changing enterprise needs.

BNC also has a strong position in the small business marketplace, which stems from its understanding of the needs of small businesses and its ability to provide them with networks that are reliable as well as easy to buy, install and manage. With BNC's solutions, small businesses can spend less time dealing with technology and more time focusing on their growing business.

Future Trends:

Enterprise networking has evolved rapidly over the last 10 years. The departmental workgroup networks spawned by the adoption of Ethernet and the explosion of PC use have developed into enterprise-wide client/server networks, and those networks have been extended via the Internet. Originally a research tool, the Internet has grown quickly to become a major influence on the design and deployment of networks.

4

Unfortunately, however, the Internet has brought mixed blessings. Challenges, such as weak security, poor performance, and complexity in the data center, often undermine the positive attributes of reach, economies of scale, and speed of deployment. As network usage continues to grow within the enterprise and expands to include third parties such as business partners and customers, networks have to evolve to improve the end user's experience of the network and the return on investment to the enterprise, while freeing up the IT manager to focus on delivering business benefits.

Today's network must provide a firm foundation to satisfy a business' strategic goals: acquiring and retaining customers, conducting commerce, providing a competitive advantage, and delivering profits. To fulfill this purpose, the network of the 21^st century must deliver greater network performance, availability, and scalability in a cost-conscious environment. The network must become focused on supporting the needs of individual users, not solely on the delivery of raw data or generic applications. Intelligence must be pushed to the edge of the network to securely provide immediate access to relevant data to any user at any location.

BNC has a unique approach for delivering network capabilities to enterprise customers. The approach is to put specific features at the point in the network where they can be most effective and where it makes most sense for them to be. Unlike many competitors which choose to design an increasingly complex array of features into large, expensive switching engines at the core of the LAN where they are farthest from the end user, BNC moves the functionality closer to end users and to the applications. This approach offers more flexibility in network design by allowing IT managers to easily select and deploy the capabilities they want when and where they need them, resulting in a more cost effective, "pay-as-you-grow" implementation. By distributing these capabilities to the most effective places, the demand placed on individual network components is reduced, and the potential performance and reliability of the network is increased.

Previously used only by larger organizations, such as banks, hospitals, and stock exchanges, high-availability networking is now an affordable solution for enterprises that require their business systems—from interoffice communications, to customer service, to procurement, to time tracking and billing, sometimes even the storefront itself—to always be available.

Our recently announced XRN™ (eXpandable Resilient Network) technology for core switching demonstrates how BNC is changing the way that networks are built to deliver better performance, availability, and scalability. With XRN technology, companies no longer have to make huge up-front investments or significantly increase their IT staff to ensure that their core network backbone is continuously available to users who need them. XRN technology complements our existing modular core switch offering, allowing network managers to build affordable network cores with exceptional performance and flexibility. With XRN technology, multiple interconnected Gigabit switches behave as a distributed switching fabric that grows with the network, without the physical limitations, or disaster recovery risks, of a centralized core device.

Beyond the LAN core, BNC is developing networking solutions to address real needs faced within the enterprise:

Security—Companies need to tighten security measures in order to protect users, intellectual capital, and assets through enhanced authentication, encryption and control.

Content—To improve performance and speed for all network users, companies need to push content to the edge of the network more quickly and find better ways to distribute relevant information rapidly across the Internet. Different levels of performance are required for different users, depending on their network priority (for example, customers over administrative staff, voice over data traffic), their location, and their device access.

5

Mobility—Today's employees need more portable network access enabling them to be both mobile and location-independent. Whether the user goes across the room or across the world, the network should be able to find them, identify them, and give them access.

Collaboration—Companies increasingly look to leverage the ubiquity of the Internet to simplify the way that people interact using integrated voice, video, and data communications. Soon, users will be able to use one messaging system to collect voicemails, emails, and faxes, and to benefit from better communications through shared applications.

BNC uniquely offers scalable, high-performance solutions that meet the needs for security, content, mobility, and collaboration. BNC combines rich user functionality with the ease of use required to create the emerging networks of the future.

We are fully committed to working with our worldwide base of over 55,000 resellers and channel partners. While the majority of product sales are to partners in our two-tier distribution channel, which is utilized by both BNC and BCC, we also work closely with systems integrators, major telecom service providers and direct marketers. BNC also maintains a field sales organization that works alongside our partners to assist them in achieving their business goals.

Our two-tier distribution channel is comprised of distributors and resellers. Distributors are the first tier of the channel providing global distribution, logistics, market development and other services. Distributors generally sell to the second tier of the channel, comprised of value-added resellers (VARs) and other channel partners.

3Com's resellers provide value to end users' solutions through application, technology, or industry-specific expertise, and product and/or service offerings that complement 3Com networking solutions. To support our resellers, we maintain a comprehensive partner program, the Focus Partner Program. The partner program identifies three levels of partners (Gold, Silver and Bronze) based upon different factors such as expertise in 3Com products and solutions, certifications, customer reach, ability to support pre and post sales services, revenue, and growth potential. This program provides the resellers with varying benefits and services including marketing, training, sales support, service and support, and project help desks.

BNC's worldwide sales team focuses on the various channels mentioned above. While the specifics can vary slightly based on geographic differences, in general they can be summarized as follows. Distributor

7

account managers support the distributors in their activities to support their businesses from marketing through to supply chain and sales out management. Reseller sales support ranges from telephone account management for the Bronze partners through to field based sales support for Gold or Silver accounts. Further, field-based resources work closely with our resellers to assist them in their work with end users to generate and close sales opportunities. In some countries specific sales resources focus on supporting targeted service providers and systems integrators.

In addition, BNC leverages 3Com's corporate marketing efforts, which focus on increasing 3Com awareness, consideration and preference with our target enterprise and small business customers to create demand for 3Com products with our channel partners. In addition, marketing supports activities to attract, retain and develop partner channels to ensure we have the right channel partners to support our business and to help their businesses to be successful. These activities range from advertising and direct marketing activities, through sales tools, collateral and training to promotions and incentives.

Competition:

BNC competes in the enterprise network infrastructure market providing products and solutions for voice and data as well as wired and wireless communications. While BNC competes with a small number of large firms, including Cisco Systems, Inc. (Cisco) and Nortel Networks Corp. (Nortel) in the overall market, BNC also competes with various other companies in specific market segments or product categories.

BNC's principal competitors in the enterprise networking market today include Avaya, Inc. (Avaya), Cisco, Enterasys Networks, Inc. (Enterasys), Extreme Networks, Inc. (Extreme), Hewlett Packard Company (HP), and Nortel. In the small business market, BNC competes with Allied Telesyn, Inc., D-Link Systems, Inc. (D-Link), Linksys, and NetGear, Inc. (NetGear).

The primary competitive factors in BNC's market are as follows:

•

BNC's research and development approach focuses internal investments upon those core activities that are necessary to deliver differentiated products or planned product cost reductions. This is particularly true for newer technologies where it is important to develop internal intellectual property or platforms for future

8

product offerings. For non-core activities that may include mature technologies or widely available components, the company leverages third parties for sourcing or contract work for that portion of the product development. This two part approach increases BNC's ability to bring products to market in a timely and low cost manner and ensures that the company is focused upon those product attributes that matter most to our customers.

Research and development investments in application specific integrated circuits (ASICs) and value-added software remain a high priority for the company. ASICs provide higher performance, innovative features, as well as cost benefits. Gigabit switching ASICs such as the ones developed for the company's XRN technology deliver high, non-blocking performance as well as unique combinations of capabilities such as Distributed Resilient Routing, Distributed Device Management, and Link Aggregation Clustering. ASICs used in the company's networked telephony solutions enable powerful features and provide key cost advantages. Along with our ASICs, value added software provides differentiation across our product lines. In many cases, sophisticated software underlies the reliability and ease of use that our customers have grown to associate with 3Com products—"It just works." Examples include everything from self-configuration capabilities in our wireless LAN access points and 10/100 switches to automatic prioritization of networked telephony traffic traversing our Switch 4400.

In fiscal year 2002, targeted research and development investments resulted in the release of important enhancements and additions to our product lines. Among these were the addition of significant new product offerings in Layer 3 Gigabit switching, networked telephony, and wireless LAN, among others. In the future, we will continue to invest in areas that deliver growth for the company and value to our customers such as 10 Gigabit Ethernet, XRN technology, and Unified Communications.

Business Connectivity Company

3Com's Business Connectivity Company is a leading provider of easy to use, reliable, high-performance connectivity solutions at the edge of the network that enable users to access information. BCC develops and sells a full portfolio of connectivity solutions that provide LAN connectivity at the edge of the network. The technologies supported by our products include all speeds of Ethernet, wireless LAN, Bluetooth, and LAN/Modem combination products. We offer these technologies in all of the common user configurations and form factors including personal computer interface (PCI) NIC, PCI-X NIC, PC Card, Mini-PCI, universal serial bus (USB) interface, ASICs for LAN on the Motherboard (LOM), and intellectual property for licensing our connectivity technologies to third parties.

BCC's products have a long-standing reputation for providing easy to use, reliable, and high performance connectivity solutions for notebook, desktop, and server systems. This success is evidenced by our partnerships with major PC OEMs and our large installed base in corporate enterprise.

Industry Background:

As discussed earlier, 3Com introduced the first Ethernet NIC for PCs in 1983. Since then, we have introduced a wide range of innovative products that have changed the way we live, work and communicate. Today our products connect desktops, servers and mobile users. Our Ethernet adapter products now reach 1 gigabit per second speeds over wired infrastructure and 11 megabits per second (Mbps) in a wireless environment. Our products allow users to access information from their desk, conference rooms and remotely via v.92 technology and our Mobile Connection Manager software. This has allowed our customers to improve productivity and collaboration, while adapting to the ever-changing needs of today's increasingly mobile workforce.

We have become the preferred supplier of Ethernet connectivity to the Fortune 1000. As the market evolved and matured, niche competitors entered the market and, over time, attempted to become mainstream players. Companies, including Western Digital Corp., Lannet Company, Inc., SMC Networks, Inc., Cogent Communications Group, Inc., Xircom, Inc., and Proteon, have either sold their business to one of the remaining players or have left the market entirely. Today, BCC has focused

9

networking competitors including D-Link, Accton Technology Corp. (Accton), and Linksys in Taiwan, and major silicon providers including Intel Corp. (Intel) and Broadcom Corp. (Broadcom) based in the U.S. The Taiwanese competitors are typically focused on board level products, while Intel and Broadcom are focused on silicon products. These two business models are the result of 20 years of innovation and consolidation in the Ethernet connectivity market.

Markets and Customers:

The primary customer focus for BCC is enterprise customers, including Fortune 1000 corporations. BCC's success in addressing this target market can be illustrated by a recent study by Instat/MDF (June 2002) showing that 3Com continues to maintain a significant lead in NIC brand awareness. In this survey among enterprise respondent's 3Com had 61.3% share for current NIC usage and 54.8% for future NIC deployments.

BCC's solutions are targeted for worldwide distribution to enterprise and small business customers via PC original equipment manufacturers (OEMs) and VARs. BCC sells directly to PC manufacturers, who integrate our connectivity products primarily into their commercial PC product offerings. BCC branded products are sold primarily though our two-tier distribution channel, which leverages the capabilities of our resellers and channel partners.

Future Trends:

As connectivity evolves, there has been a transition from higher priced NICs to lower priced ASICs that are installed on the PC motherboard in a LOM configuration. Looking forward, connectivity products will increasingly reside in smaller and lower priced form factors, designed in coordination with the PC motherboard itself. Virtually all commercial PCs and a growing percentage of consumer PCs are now configured with LOM with either a LAN ASIC or LAN connectivity integrated into the Bridgechip set. The Bridgechip set provides the interfaces between the processor and various peripherals in a PC including the PCI bus and the USB ports. In addition, the Bridgechip set vendors have integrated additional functions including graphics, audio, and now LAN networking into their silicon. This migration in function from PCI cards or stand-alone ASICs into the Bridgechip provides a significant cost reduction to the PC manufacturer. As this trend continues, this configuration will become the form factor of choice for connectivity products, significantly impacting and eroding the market for NICs.

In addition to changing form factors, users are demanding higher speed connectivity products. BCC anticipates that a growing number of connectivity products will be based on Gigabit Ethernet (GbE) (10/100/1000) line speed. In fiscal 2003, BCC expects to introduce its first 10/100/1000 product for desktop PCs.

As BCC moves forward, it looks to utilize its strong brand, installed base and market share positions, as well as its intellectual property portfolio, to maximize the profitability of 10/100 connectivity products. BCC will leverage alliances, which provide cost effective product development, allowing for the effective extension of these legacy products. BCC will look to bring this technology to new markets—in untapped geographic markets, and in new configurations, including integrating 3Com connectivity in Bridgechip sets and new non-PC applications. Also, by utilizing low cost, outsourced NIC and LOM products, BCC will engage the consumer PC segment, where products are often sold through catalogue and e-tail sales channels.

BCC is uniquely positioned to license its strong intellectual property portfolio in connectivity, thus providing the company with future royalty streams, with minimal overhead investment. Ultimately, BCC will focus on yielding the greatest possible contribution margin and cash generation through the extension of the 10/100 business.

BCC will continue to invest in developing products based on emerging connectivity standards including higher speed versions of Ethernet, wireless Ethernet, and Bluetooth products. A major factor in BCC's

10

success has been our focus on ease of use, reliability, and performance. Our customers expect a 3Com product to install easily and to operate reliably over the life of the system. Further, they expect a 3Com solution will provide excellent performance, which will enhance the corporation's productivity, by providing timely access to information on the network. These attributes will be carried into 3Com's future product development efforts.

Product Offerings:

BCC develops four categories of solutions: 1) wired LAN connectivity products that enable computers as well as non-PC devices to connect to Ethernet networks, 2) wireless LAN connectivity products, including 802.11 and Bluetooth compatible products, 3) Secure NICs, including embedded firewall products, for applications that require high security of network devices, and 4) Network Jack, a 4-port Ethernet switch in a standard single faceplate form-factor that allows network managers to cost-effectively add switch ports to the network while avoiding costly new cable-pulls.

Wired LAN Connectivity:

BCC builds products that enable computers as well as non-PC devices to connect to Ethernet networks. Building on proprietary ASICs, hardware, and software, BCC is one of the world leaders in providing 10/100/1000Mbps Ethernet connectivity. Products include NICs, mini-PCI form factors, LOM, and PC Card form factors. Customers for these products include Tier one and Tier two OEM PC manufacturers, as well as key original design manufacturers (ODMs). BCC also leverages 3Com's distribution and VAR channels to sell branded products directly to end-users.

BCC offers both Copper and Fiber NICs that provide Gigabit connectivity. Gigabit NICs have been primarily sold for servers. Looking forward, as Gigabit technology becomes more widely adopted, BCC will sell Gigabit NICs for desktop PCs. Future products will also include Dual-Port Copper and Fiber Gigabit server NICs. BCC will continue to sell GbE products to both major OEM customers, as well as through its distribution channel. BCC will also look to invest in future GbE technologies, such as 10 GbE NICs for server applications.

Wireless LAN Connectivity:

BCC builds 802.11 and Bluetooth compatible wireless products that enable users to stay connected to information while at their desk or while roaming within the enterprise or the home. The productivity increase associated with this ease of information access is driving many corporations to deploy wireless networks. Based on proprietary software for drivers and the user interface, BCC products include PC Cards based on the 802.11 standard, Bluetooth PC Cards, Bluetooth USB modules, and 802.11b USB modules. BCC will focus primarily on the distribution and VAR channels to sell branded products directly to corporations and to end-users.

Secure NICs:

BCC has long been developing NIC connectivity features that provide value through lowering the total cost of ownership to corporations. Our NIC management features are de-facto standards in many Fortune 1000 IT departments. In fiscal year 2001, BCC introduced our first NIC with a dedicated processor capable of off-loading operations from the PC including off-loading 3DES (Data Encryption Standard) encryption in a Windows 2000 environment. This intelligence at the edge of the network is a key component of our strategy to continue to offer features that provide value to our corporate customers.

In January 2002, BCC began shipping an Embedded Firewall (EFW) as the next step in our NIC management strategy. This product provides a high level of LAN security by controlling access to the network. By utilizing a centrally controlled, tamper-resistant management console, we assist IT departments by providing the control they need to protect their network assets from unauthorized access.

11

Network Jack:

As connectivity evolves, intelligent solutions at the edge of the networks are adding increasing value. The Personal Systems Division is creating a series of products to capture this potential. The products match the traditional single gang faceplate size.

Launched in January 2002, the NJ100 Network Jack provides switching capability in a compact form factor that quadruples connectivity, eliminating the need for expensive cable installation. A key feature of the NJ100 Network Jack is the ability to receive power over ethernet (PoE) or from a local power supply. The product can also forward power to connected devices that comply with the current IEEE 802.3af PoE draft standard. Currently targeted at education, government, and medium enterprise customers, the NJ100 Network Jack is an ideal upgrade solution, especially in connectivity-constrained environments. The Network Jack family of products will expand to add management features to serve the broader enterprise segment.

Sales, Marketing and Distribution:

BCC utilizes a two-pronged sales channel strategy to address its target customers. By using our broad two-tier distribution channel as described earlier, and a separate OEM channel focused on PC manufacturers, BCC has high volume channels designed to reach and support enterprise customers worldwide. BCC also maintains a field sales organization that works alongside our partners to assist them in achieving their business goals. BCC's second sales channel is focused on the major PC manufacturers and leading ODMs. These sales teams provide the levels of dedicated in-depth technical support and account management required by these major customers.

BCC's OEM sales group is composed of dedicated, cross-functional account teams focused on major PC manufacturers and regional OEM sales teams focused on smaller regional OEM customers. The dedicated account teams manage the business relationship and the customer. This management includes coordination of the supply chain, quality, and logistics in addition to managing pricing and demand forecasts. The coordination is a key function as many PC customers have international manufacturing locations and are increasingly using contract manufacturers like the ODMs who will design and manufacture systems to the PC vendors specifications. This change in design and production strategy requires close interaction within BCC's OEM sales group.

Since a large percentage of PCs are sold by the non-brand name PC companies, BCC has a separate OEM sales group focused on the smaller, regional PC companies. A dedicated sales focus is required to address this segment as the regional OEM's business tends to be very opportunistic and deal-based. Close cooperation is required to ensure the BCC solution is appropriately positioned to support the OEM's ability to win their bid.

BCC, like BNC, also leverages 3Com's corporate marketing efforts directed at our channel partners that promote 3Com brand awareness and preference, as well as help their businesses to be successful.

Competition:

Major Taiwanese connectivity vendors, including D-Link, Accton, and Linksys, have established positions in the low priced (less than $20) segment of the NIC market and have created consumer-oriented brands in the U.S., Europe, and Asia. The Taiwanese competitors typically compete on price and tend to be market followers. We believe we provide superior quality, service and support compared to these players. Several vendors have succeeded in creating a corporate business in selected markets, such as D-Link in France, but for the most part, the Taiwanese competitors are still attempting to create an up-market image for their products.

Intel entered the Ethernet NIC market in the early 1990s. Intel's stated goals were to diversify into related markets and create demand for faster processors. Intel is an aggressive competitor who is well positioned

12

to compete for the mind share of the Fortune 1000 chief information officers due to its position in processor sales. Initially, Intel focused on NICs or board-level products. Today, Intel is focused on silicon, especially ASICs and integrated Bridgechip sets they sell to PC OEMs. In the past, BCC has maintained—or in some cases, grown—market share in sub-segments of the NIC business. Over the past year Intel has been successful in the ASIC and Bridgechip market, where it has used proprietary interfaces and its strength in processors and sales to create a strong competitive position. BCC has countered with partnerships and alliances to create solutions that offer compelling products in this space. However, as we move forward, silicon and Bridgechip will become a bigger portion of the annual total connectivity shipments.

Research and Development:

BCC utilizes its engineering teams to internally develop high volume basic connectivity products utilizing proven technologies, including our wired LAN connectivity ASIC, NICs, and PC Card products. Corporate customers value the stability of the software image and robustness of design as key product attributes. These features along with the extreme cost focus require in-depth knowledge of our products that is only available to our internal design teams.

In BCC's growth markets a limited investment methodology will be used, especially in low volume or in new technology segments. In these markets BCC will leverage alliances to quickly bring new products to market. Our product design approach will be to utilize outsourced hardware with product differentiation provided by software (drivers and firmware), product quality assurance, and support. As market segments achieve high volume we may bring these development efforts in-house as we have done with the basic connectivity products.

CommWorks Corporation

CommWorks Corporation (CommWorks) develops and deploys carrier-class, IP-based multi-service access and service creation platforms for telecommunications service providers. Our products allow telecommunications service providers to offer existing and new services with the same high availability and reliability as the traditional telecommunications network, but at much lower cost. In addition, CommWorks combines expertise in both custom development and network integration to deliver highly specialized solutions that address the specific challenges faced by telecommunications service providers.

CommWorks' IP-based networks deliver greater functionality at significantly reduced cost and create the ability to offer multiple services over a common infrastructure. Our networks feature several key characteristics, including:

•

Scalability—Service providers need the ability to start small and grow the network as demand increases. CommWorks gives service providers the ability to utilize their existing network and add new services over time without major additions of hardware;



•

Reliability—In voice communications, the benchmark for quality and reliability is the traditional public switched telephone network (PSTN). CommWorks networks deployed today by some of the world's largest service providers are delivering voice quality and reliability on a par with—and often better than—the traditional PSTN;



•

Multiple services, common hardware—We offer service providers an IP platform based on a common infrastructure that allows them to deliver multiple services. Regardless of the transport medium (wireline, wireless, broadband) or the type of traffic (voice, data, fax, video), we allow the service provider to turn the traffic into revenue-generating services; and



•

Open architecture—Service providers do not want to be locked into a single vendor. Our networks feature open, standards-based interfaces for multi-vendor connectivity. This encourages service providers to deploy best-of-breed components and allows them to introduce new services in less

13

time than for traditional network infrastructures. Also, our commitment to standards and open interfaces allows service providers to customize solutions independently at each tier to address individual customer needs.

CommWorks' product portfolio includes the three key components of next generation networks—wireline access systems, wireless access systems and a media independent softswitch—that are critical to enabling complete next generation data and voice services to both fixed and mobile subscribers.

CommWorks has achieved certification under the Telecommunications Leadership 9000 (TL 9000) program. Specifically designed and tailored for the telecommunications industry, TL 9000 establishes a common set of quality system requirements for suppliers of telecommunication hardware, software and services, including cost and performance-based metrics that measure product reliability and quality.

Industry Background:

CommWorks' exclusive focus is on the telecommunications service provider market. Historically, the telecommunications industry has been heavily regulated and dominated by a small number of incumbent service providers and equipment vendors. As a result, evolution of the circuit-switched technologies underlying the industry's public telephone networks has been slow and innovation in new service offerings and pricing has been limited. The telecommunications industry landscape began to change, however, in response to the Telecommunications Reform Act of 1996, which deregulated the U.S. telecommunications market and removed the barriers that previously restricted service providers to a specific geography or offering. Over the past several years, deregulation has been progressing rapidly in other markets worldwide as well.

Deregulation worldwide has fostered the creation of new operators to expand competitive service offerings to customers. As a result, deregulation has served to dramatically increase the number of competitive service providers, both facilities-based operators and resellers, and the number of network infrastructure manufacturers supporting them. This increased level of competition between new entrants and incumbents has resulted in lower prices for voice transport, long distance and wireless services. Such lower prices and lower revenue growth rates have combined to exert downward pressure on service provider margins and profitability. In addition, the collapse of the Internet/telecommunications bubble beginning approximately two years ago has led to the failure of many new entrants and has contributed to creating a significant excess of network capacity over market requirements. Combined, these two factors—pricing pressures and excess network capacity—have resulted in decreased levels of capital investment in new equipment by both competitive and incumbent service providers.

Markets and Customers:

CommWorks builds IP-based networks for many types of telecommunications service providers, including incumbent local exchange carriers (ILECs); interexchange carriers (IXCs); post, telephone and telegraph administrations (PTTs); competitive local exchange carriers (CLECs); wireless service providers; internet service providers (ISPs); and other alternative service providers. We operate on a global basis, and our customers include many of the world's major telecommunications service providers.

Future Trends:

In the near term, revenue growth for the telecommunications industry is expected to continue to decline. Projected growth in revenues for broadband data, wireless data, and enhanced services offerings is not expected to be sufficient to offset projected declines in revenues for traditional business and consumer long-distance services. As a result, in the near term, we anticipate the following trends:

•

Business models for service providers likely will reflect slower growth and reduced profitability, leading to additional consolidation within the industry;

14

•

Sales cycles likely will lengthen as service providers extend the useful lives of their existing networks and exhibit a low tolerance for risk related to the deployment of new technology to support service innovation;



•

The migration from circuit-switched to packet-switched networks likely will occur over a longer period than originally anticipated;



•

Capital expenditures by service providers likely will continue to be constrained for the foreseeable future; and



•

The number of equipment vendors likely will decrease and those that remain must have the scale and scope to manage extended sales cycles with fewer customers.

Over time, however, the market for IP-based networks such as those developed and deployed by CommWorks is expected to stabilize and resume growth. To compete effectively in the expected near-term and longer-term industry environments, CommWorks' objective is to capitalize on its strengths in the following areas:

•

Strong presence and incumbency with major service providers worldwide;



•

Global customer engagement experience and support structure;



•

Complete product lines supported with research and development teams located throughout the world;



•

A long-term hardware platform focus and commitment with the Total Control® 1000 and Total Control® 2000 platforms;



•

Demonstrated packet telephony experience with major service providers worldwide, based on significant, billable traffic carried on CommWorks gateways and softswitches;



•

Proven ability to tailor equipment, software and services to meet customers' unique requirements and needs;



•

Solutions focused on the market for packet-based enhanced services, sometimes referred to as "microservices"; and



•

Influential role in the standards definition and adoption process.

Product Offerings:

CommWorks' product solutions are based upon a three-tier packet-based architecture. The CommWorks® three-tier architecture makes it possible for service providers to integrate with existing infrastructures, customize solutions independently at each tier to address individual customer needs and utilize innovative technologies to deliver an array of new IP-based enhanced services to their customers.

•

Tier 1 of the CommWorks architecture, the media processing layer, employs media gateway functions to integrate multiple types of traffic and accommodate disparate access networks.



•

Tier 2, the control and network and service management layer, features the CommWorks softswitch to bridge different signaling and provides multilingual call control protocols enabling multimedia traffic to traverse disparate networks.



•

Tier 3, the service creation layer, provides an open service creation environment that leverages open interfaces and utilizes strategic partners to enable rapid application and service deployment. This encourages service providers to deploy best-of-breed components and allows them to bring new services to market faster.

The Total Control 2000 system architecture will provide the highest density available in the industry. Also, unlike many competitors' products that support one form of voice coding, the Total Control 2000 will support multiple voice coders to ensure that the greatest call density is achieved regardless of what is negotiated during the call by the voice device.

The Total Control 2000 uses next generation switching technology based upon a true IP switching fabric that offers complete switching performance upgradability. This capability, together with the Total Control 2000 platform's inherent multi-service design, will enable service providers to easily expand the platform to support new services and access technologies. Open interfaces and true multi-service capabilities provide unique advantages such as faster time to market, service customization and network efficiency.

Wireless:

CommWorks' wireless systems consist of hardware and software components residing in Tiers 1 and 2 of the CommWorks architecture. Using the Total Control 1000 platform and CommWorks software, wireless service providers are able to offer wireless data access in their CDMA (Code Division Multiple Access)-based networks.

The Total Control 1000 Wireless InterWorking Function (IWF) High Density Gateway enables service providers to converge wireless voice services with newer data applications across an integrated infrastructure. The CommWorks IWF is a second generation (2G) hardware and software platform that serves as a gateway from the wireless network, giving subscribers access to the Internet, corporate intranets, PSTN dial-up and fax services. The IWF system resides within a service provider's central office or switching center and connects directly to the mobile switching center, serving as a gateway between the CDMA wireless network and various wireline networks. The Total Control 1000 2G IWF High Density Gateway is deployed in CDMA networks throughout the world.

CommWorks' third generation (3G) wireless capabilities allow wireless service providers to offer enhanced wireless data services through a platform that positions their networks for future growth, cost savings and new revenue-generating services. CommWorks' 3G wireless system, based on 3G cdma2000 standards, interfaces with CDMA network infrastructure and delivers significantly higher data speeds. CommWorks' 3G wireless system was deployed in the world's first commercial 3G CDMA network, as well as in the largest 3G CDMA networks deployed today at customers including KDDI, Sprint PCS, SK Telecom, TELUS Mobility and Verizon Wireless.

Softswitch:

The CommWorks softswitch product line anchors Tiers 2 and 3 of the CommWorks architecture, providing call treatment, signaling, control and service creation across multiple access media—wireline, wireless, broadband or any IP-connected subscriber. With its open, standards-based modular architecture, the

16

CommWorks softswitch allows service providers to easily support new and emerging access technologies and to introduce a variety of end-user and service provider network services. By providing consistent call control and applications across all devices, CommWorks softswitch allows service providers to more readily target vertical markets, enterprises and other groups with microservices (i.e., packet-based enhanced services).

Applications:

CommWorks' core IP-based telephony systems provide service providers with a flexible, lower cost alternative for transporting voice calls across their networks transparently to end-users. In addition, and perhaps more importantly, service providers can utilize the same IP-based voice infrastructure to enable new microservices, which create opportunities for additional revenue and competitive differentiation. CommWorks' open and flexible softswitch product allows service providers to utilize their own developers, allowing creativity to move to an Internet-style and giving service provides a time-to-market advantage on new services that cannot be achieved with the traditional PSTN infrastructure. Applications enabled through the CommWorks' softswitch architecture, including a variety of new microservices, include the following:

Hosted Voice Services.    Where service providers provide basic data services today, they now have the option with this application to offer a PBX or Centrex replacement solution to their business customers utilizing the same data connections already in place. Such a solution eliminates the issues of managing PBX office voice systems—in particular the complexity of adds, moves and changes to users of the businesses voice network—and allows the telephone to take on the same degree of mobility as experienced today with desktop computers. In addition, an integral microservice called Find me-Follow me allows end-users to set rules within their voicemail system to determine notification and forwarding options for incoming calls simply by entering their preferences via a Web-based interface. For any Hosted Voice Service, the ability to offer IP-based conferencing is important. This microservice enables enhanced conferencing features, such as the ability to host "on the fly" conference calls. IP conferencing is an ideal solution for converged IP-based networks where multimedia conferencing (combining audio, video and text) is required and must operate seamlessly to connect end-users across wireline and wireless networks. Conferencing is also a premium service for service providers, and can contribute significantly to revenues and profitability.

Enhanced IP Voicemail and Unified Communications.    This solution provides a compelling option for wireline and wireless service providers with aging legacy voicemail systems. Legacy voicemail systems have matured to an end-of-life state and provide no option for migration to next generation IP-based services. The CommWorks enhanced IP voicemail solution allows service providers to integrate their current circuit-switched voicemail systems with the CommWorks platform to create a customized system that meets the exact requirements of their customers and networks, from a complete voice mail system to a comprehensive unified communications service. Voicemail service to end-users is completely transparent, enabling a smooth transition. CommWorks' Unified Communications capability allows end-users to combine voice, e-mail and fax messages in one universal mailbox and manage them with a single device of their choice—telephone, cell phone, e-mail client or personal digital assistant. An integral Message Alert & Message Delivery microservice allows wireless subscribers to simplify management of multiple voicemail accounts (office, home, cell phone). Message Alert accesses these multiple voicemail boxes and notifies the end-user of incoming messages via a mobile short messaging service (SMS) or other device (e.g., mobile phone, pager, personal digital assistant; etc.). In addition, Message Delivery, commonly known as "mailbox on the fly", allows service providers to offer fee-based voice messaging to customers who want the convenience of voicemail without having to pay for a monthly service. The service provider can set up a temporary mailbox for the customer, who can access messages for a fee.

17

Alternate Calling Plans.    A Multistage Calling microservice gives service providers additional options for offering two and three stage dialing models for prepaid and calling card applications. Prepaid calling allows subscribers to pay in advance or use traditional calling cards for phone service, most typically long distance service. Service providers may also provide PC-to-Phone Calling using a number of IP-based clients, such as Microsoft Corp.'s enhanced Windows Messenger client, Pingtel's soft client, and others; with this application, CommWorks can enable PC-to-phone capabilities with toll quality voice calls.

Voice Portal.    This microservice allows end-users to obtain web-based information over the telephone, and is enabled by giving customers access to Voice Extensible Markup Language (VXML)-enabled websites or other related resources. Content can either be provided by third party content providers or customized for a specific program offering by service providers. This service also allows end-users to issue short commands to receive information on demand and to use services like voice dialing, teleconferencing and directory assistance.

Professional Services:

CommWorks offers a variety of professional services that are integral to its product offerings. Through our broad portfolio of carrier-class professional services and solutions, which encompass all phases of the network lifecycle, we help customers plan, deploy and support advanced IP networks. CommWorks strives to assist our customers with their business challenges, including reducing time to market, cost, complexity and business risk. Our service offerings include the following:

Our education services feature world-class content developers and training

18

professionals, flexible delivery options and primary delivery processes designed around customizing training to meet the customer's specific needs.

Onsite Engineering Support.    A dedicated engineer serves as the customer's single point of contact, becoming intimately familiar with their business and network environment to provide more personalized assistance. Dedicated engineers proactively anticipate and resolve issues to avoid future problems, and meet with the customer team regularly to review support activity and provide expert assistance.

Online Support.    CommWorks utilizes its technical support website, TOTALService Online, to provide customers with access to one of the most comprehensive technical support resources in the industry. Available 24 hours a day, seven days a week, this website provides a variety of value-added services. Key available resources include online technical support cases, a comprehensive software and documentation library and archive, a knowledgebase of technical tips, online user forums and a variety of custom web page options.

Remote Technical Support.    CommWorks' remote technical support services are designed for the specific needs of today's service providers. We provide a single tier support structure, rather than the traditional multi-tier support structure. CommWorks remote technical support provides global, around-the-clock access to networking experts—a team of highly trained engineers who deliver consultative support using an up-to-date laboratory dedicated to customer support operations and who have an escalation path directly to the CommWorks research and development engineers who designed the product. Customers using these services are connected directly to an engineer with expertise in their specific application, instead of being routed to an administrative queue or being forced to leave voicemail with the hope of receiving a reply on a timely basis.

Sales, Distribution and Marketing:

CommWorks conducts its sales and marketing activities on a worldwide basis primarily through a direct field sales organization and, in some markets, through resellers and other strategic marketing partners. The company also has a number of marketing programs to support the sale and distribution of its products and to inform existing and potential customers about the features and the performance of its products and services.

Sales and Distribution:

CommWorks presently has field sales offices throughout the world, providing coverage in all key markets. The role of the direct field sales organization is to establish and maintain direct relationships with key service provider customers, in order to achieve direct sales to these accounts and to develop leads for potential sales to these accounts by our value-added resellers. In performing this role, the direct field sales organization assists current and potential customers in developing solutions to complex networking challenges and, in doing so, differentiates the features and capabilities of CommWorks' solutions from competitive offerings.

To complement its direct field sales organization, CommWorks has entered into sales agreements with a variety of value-added resellers, including distributors and network and system integrators. Such resellers enhance our ability to sell through their broad product and service fulfillment capabilities. Our sales agreements with resellers generally are made on a non-exclusive basis and provide the resellers with discounts and other terms and conditions reflective of the volume of business conducted.

CommWorks also has established strategic alliances with selected original equipment manufacturers and other marketing partners. Through these relationships, CommWorks is able to:

•

Leverage a partner's account presence and relationships in order to reach particular geographies, markets and customers; and

19

•

Collaborate with a partner to fill gaps in their respective offerings and deliver more complete and robust solutions to potential customers.

Marketing:

CommWorks' marketing efforts involve a variety of activities, including direct marketing, end user rebates and promotions, participation in industry trade shows, an active public and industry analyst relations program, publication of technical and educational articles in industry journals, and a publicly available web site. In addition, we have introduced two key programs—the "CommWorks Community of Partners" program and the "CommWorks Compatible" program.

The CommWorks Community of Partners program is designed to augment the CommWorks three-tier architecture, extending product and service capabilities. A flexible architecture with open interfaces, the CommWorks architecture allows interoperability and compatibility with industry-leading partners, bringing a variety of feature and capability choices for service providers and their customers. Through the CommWorks Community of Partners program, CommWorks offers its service provider customers a range of solutions no single vendor could provide and enables them to create new services efficiently and effectively, increasing their revenue potential.

The CommWorks Compatible program showcases vendor solutions that are technically and functionally compliant with the CommWorks architecture in the enhanced data services, Voice over IP (VoIP) and wireless market segments. Products identified as "CommWorks Compatible" must pass defined tests, and enjoy greater brand visibility since they are proven to operate properly within a CommWorks solution created to address a customer's specific business need. Customers will be able to readily identify vendor solutions that fit into their CommWorks-enabled networks.

Competition:

CommWorks competes in the telecommunications infrastructure market, providing next-generation IP infrastructure. The market is characterized by rapid change, extended sales cycles, converging technologies and a conversion from traditional circuit-switched infrastructure to next-generation packet-switched infrastructure.

CommWorks competes with numerous vendors in each of our product categories, and we expect competition to intensify in the future. However, we expect to see the number of smaller, niche vendors decrease over time as venture capitalists become increasingly more selective in their investments and service providers exhibit an increased reluctance to select smaller, less-well-known vendors.

We believe that our principal competitors are the traditional telecommunications equipment vendors, as well as certain well-funded and well-staffed start-up companies. Principal competitors include Cisco, Comverse Technology, Inc. (Comverse), Lucent Technologies, Inc. (Lucent), Nortel and Sonus Networks, Inc. (Sonus).

The principal competitive factors in the markets in which CommWorks competes include:

•

Market presence;



•

Size of installed base;



•

Experience in providing standard-based products to service providers;



•

Performance;



•

Price;



•

The ability to provide new technologies and products;

20

•

The ability to provide value-added features, reliability and investment protection; and



•

Conformance to industry standards.

We believe we compete favorably with our competitors with respect to each of the above listed factors. In addition, we believe that 3Com currently exhibits a degree of financial strength and flexibility that exceeds that exhibited by certain of our competitors. However, certain of our competitors have longer operating histories, greater name recognition, larger customer bases and greater resources to devote to them than we do and may be able to undertake more extensive marketing campaigns and adopt more aggressive pricing policies than we can. To remain competitive, we believe we must continue to invest significant resources in developing new products and enhancing our current products, as well as maintain customer satisfaction worldwide.

Research and Development:

CommWorks believes that its future success is highly dependent upon its ability to develop, on a cost effective and timely basis, new and enhanced products employing leading-edge technology. Accordingly, CommWorks continues to make substantial investments in research and development activities. Our current efforts reflect a strong emphasis and focus on increasing the features, performance and reliability of our products to enable new revenue generating services for our customers, as well as reduced total costs of ownership. During the past year, CommWorks has extended and enhanced its product offerings in the areas of traditional remote access, wireless access, IP telephony, enhanced IP services, network management and operational support services. Also, CommWorks has been a leading proponent of industry standards and intends to remain active in driving and supporting important standards-related activities.

Market conditions in the telecommunications industry remain severely depressed, and the timing of meaningful recovery remains uncertain. There can be no assurances that our current research and development efforts will result in new products that will be commercially successful, or that our products will not be rendered obsolete by changing customer requirements, emerging technologies or actions by competitors.

CommWorks currently conducts its research and development activities in seven design centers worldwide. As part of our ongoing cost reduction efforts, we are consolidating our research and development activities into three design centers located in Rolling Meadows, Illinois, USA; Toronto, Ontario, Canada; and Bangalore, India. We expect to complete this consolidation process during fiscal year 2003.

PRODUCT DEVELOPMENT

Our research and development expenditures in fiscal years 2002, 2001, and 2000 were $285.6 million, $535.7 million, and $597.8 million, respectively. Our research and development expenditures include efforts to create new types of products and classes of service as well as to expand and improve our current product lines, as discussed in the "Research and Development" sections of our descriptions of our BNC, BCC, and CommWorks segments.

SIGNIFICANT CUSTOMERS

For both the fiscal years ended May 31, 2002, and June 1, 2001, Ingram Micro Inc. (Ingram Micro) accounted for 15 percent of our total sales. For the fiscal year ended June 2, 2000, Ingram Micro and Tech Data Corporation accounted for 15 percent and 13 percent of our total sales, respectively.

INTERNATIONAL OPERATIONS

We market our products globally, primarily through subsidiaries, sales offices, and relationships with OEMs and distributors with local presence in all significant global markets. Outside the U.S., we have

21

several research and development groups, with the most significant group being in the U.K. We have manufacturing and distribution facilities in Ireland and a distribution facility in Singapore. We maintain sales offices in 43 countries outside the U.S.

BACKLOG

In many cases we manufacture our products in advance of receiving firm product orders from our customers based upon our forecasts of worldwide customer demand. Generally, orders are placed by the customer on an as-needed basis and may be canceled or rescheduled by the customer without significant penalty. Accordingly, backlog as of any particular date is not indicative of our future sales. As May 31, 2002, we do not have backlog orders that cannot be filled within the next fiscal year.

MANUFACTURING

We use a combination of in-house manufacturing and independent contract manufacturers to produce our products. A substantial portion of BNC products are manufactured at our Blanchardstown, Ireland facility, where purchasing, assembly, burn-in, testing, final assembly, and quality assurance functions are performed. Contract manufacturers are used to produce BCC and CommWorks products, and a portion of BNC products. We have significant contract manufacturing arrangements with Flextronics International (Flextronics) and Manufacturers' Services Limited (MSL) for the production of BCC and CommWorks products, respectively.

INTELLECTUAL PROPERTY AND RELATED MATTERS

The quality of our innovation is reflected in a substantial portfolio of patents covering a wide variety of networking technologies. This ownership of core networking technologies creates opportunities to leverage our engineering investments and develop more integrated, powerful, and innovative networking solutions for customers.

We rely on U.S. and foreign patents, copyrights, trademarks, and trade secrets to establish and maintain proprietary rights in our technology and products. We have an active program to file applications for and obtain patents in the U.S. and in selected foreign countries where a potential market for our products exists. Our general policy has been to seek patent protection for those inventions and improvements likely to be incorporated in our products or that we otherwise expect to be valuable. As of May 31, 2002, we had 790 U.S. patents (including 764 utility patents and 26 design patents) and 193 foreign patents. During fiscal 2002, we filed 189 patent applications in the U.S. Numerous patent applications are currently pending in the U.S. and other countries that relate to our research and development. We also have patent cross license agreements with other companies.

We have registered 96 trademarks in the U.S. and have registered 127 trademarks in one or more of 76 foreign countries. Numerous applications for registration of domestic and foreign trademarks are currently pending.

EMPLOYEES

As of May 31, 2002, we had approximately 4,615 regular employees, of whom 1,145 were employed in engineering, 1,538 in sales, marketing, and customer service, 933 in manufacturing, and 999 in finance, information technology, and administration. Our employees are not represented by a labor organization, and we consider our employee relations to be satisfactory.

PALM SEPARATION

On September 13, 1999, we announced a plan to conduct an initial public offering (IPO) of our Palm subsidiary. On March 2, 2000, we sold 4.7% of Palm's stock to the public in an IPO and sold 1.0% of Palm's

22

stock in private placements. On July 27, 2000, we completed the Palm spin-off by distributing to our shareholders all of the remaining Palm common stock that we owned. The distribution ratio was 1.4832 shares of Palm for each outstanding share of 3Com common stock.

RESTRUCTURING CHARGES

Beginning in the fourth quarter of fiscal 2000, 3Com undertook several initiatives aimed at both changing business strategy as well as improving operational efficiencies. Restructuring charges in fiscal 2002 and 2001 were $167.5 million and $163.7 million, respectively, which related to the realignment of our business strategy and reduction in force and cost reduction efforts. Restructuring charges in fiscal 2000 were $68.9 million, of which $9.9 million related to the separation of Palm from 3Com and $59.0 million related to implementing our change in strategic focus. These charges are discussed further in "Management's Discussion and Analysis of Financial Condition and Results of Operations."

ITEM 2. Properties

We operate in a number of locations worldwide. In fiscal 2002, we had several significant real estate related activities.

During the second quarter of fiscal 2002, we purchased properties in Santa Clara, California and Marlborough, Massachusetts, totaling 1,732,000 square feet, that were previously under operating lease arrangements, and therefore terminated those leases.

During the third quarter of fiscal 2002, we sold a 333,000 square foot office, distribution and manufacturing facility in Singapore and leased back approximately 53,000 square feet for 3Com use. This lease will expire in 2005.

During the third quarter of fiscal 2002, we vacated a 639,000 square foot manufacturing and office facility in Mount Prospect, Illinois and consolidated the operations into our Rolling Meadows, Illinois facility.

In the fourth quarter of fiscal 2002, we entered into a five year lease agreement to lease approximately 68,000 square feet of our Rolling Meadows facility to a third party tenant.

We lease and sublease to third-party tenants as of May 31, 2002 approximately 267,000 square feet of office and research and development space on our Santa Clara headquarters site, approximately 132,000 square feet of office space in our Mountain View, California leased location, approximately 137,000 square feet of office and research and development space in our Marlborough site, approximately 418,000 square feet of owned manufacturing and office space in the Chicago area, and approximately 59,000 square feet in various locations throughout North America and Europe. These agreements expire at various times between 2002 and 2008.
