                    3COM-TIPPINGPOINT MESSAGING ARCHITECTURE

SUMMARY:

The acquisition of TippingPoint is another strategic milestone demonstrating
3Com's commitment to the enterprise market. It creates the industry's most
compelling secure, converged voice and data networking solutions portfolio.

The acquisition of TippingPoint enables 3Com to more effectively compete on a
global basis at all levels, especially within large enterprises, with a secure,
end-to-end enterprise-networking solution that delivers customer value, while
profitably growing 3Com's market share and shareholder value.

The combination of 3Com and TippingPoint uniquely assembles all the necessary
ingredients to define and deliver the network of the future. The integration of
best-of-breed security into 3Com's networking infrastructure is critical to
increasing relevance among large enterprise customers, creating opportunities
for them to exercise choice by delivering a superior business solution.

OVERARCHING MESSAGES:

I. WHY MAKE A SECURITY ACQUISITION?

1.   Security and networking are converging to better protect an organization's
     investment in the network from increasingly sophisticated attacks
     originating from inside and outside the four walls
     o    The network perimeter is dissolving due to remote and wireless access
          and e-business requirements, requiring security that goes beyond the
          perimeter into the core of the network.

2.   Security must operate in real time and integrate into and behave like
     networking infrastructure, rather than be added on as an afterthought or be
     reliant on notoriously flawed operating systems

3.   Best-of-breed, purpose-built security technology is winning over
     commoditized, general purpose solutions in large enterprise installations


II. WHY TIPPINGPOINT?

1.   TippingPoint offers best-of-breed IPS technology
     o    TippingPoint is the leading provider of network-based intrusion
          prevention systems
          o    Purpose-built hardware with custom-designed silicon creates the
               Threat Suppression Engine, which can perform thousands of checks
               on each packet


                                                                               2

          o    Network-based Intrusion Prevention Systems that are designed as
               network infrastructure products which exhibit the same
               reliability, high availability, throughput, and latency
               characteristics of other networking elements. This is combined
               with extremely accurate and comprehensive inline attack blocking
               protection.
          o    Digital Vaccine Service delivers new filters on a weekly or even

          o    TippingPoint products have been widely recognized for their
               excellent engineering and performance
               o    First and only company to win the NSS Gold award in IPS
                    space (The NSS Group is the world's foremost independent
                    security testing facility)
               o    Network Protection Product of the Year award from IDG and
                    Techworld.com

                    government-validated protection profiles (analyzer, sensor,
                    scanner and system)

2.   Industry's only pure-play IPS vendor
     o    Unparalleled IPS heritage leveraging expertise in hardware, software,
          security and management. TippingPoint is generations ahead of
          competition that is in its first generation of the technology
          (TippingPoint is 4th generation).

          o    Requiring best-of-breed, most stringent security as downtime is
               unacceptable and costly

               network, making gigabit line speed performance a must


                                                                               3
