2. Special Note Regarding Forward Looking Statements This presentation contains forward-looking statements that involve substantial risks and uncertainties, including but not limited to, statements relating to goals, plans, objectives and future events.  All statements, other than statements of historical facts, included in this presentation regarding our strategy, future operations, future financial position, future revenues, projected costs, prospects and plans and objectives of management are forward-looking statements.  The words “anticipates,” “believes,” “estimates,” “expects,” “intends,” “may,” “plans,” “projects,” “will,” “would” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.  Examples of such statements include statements relating to products and product features on our roadmap, the timing and commercial availability of such products and features, the performance of such products and product features, statements concerning expectations for our products and product features [and projections of revenue or other financial terms. These statements are based on the current estimates and assumptions of management of Force10 as of the date hereof and are subject to risks, uncertainties, changes in circumstances, assumptions and other factors that may cause the actual results to be materially different from those reflected in our forward looking statements.  We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements.  In addition, our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments we may make.  We do not assume any obligation to update any forward-looking statements. Any information contained in our product roadmap is intended to outline our general product direction and it should not be relied on in making purchasing decisions. The information on the roadmap is (i) for information purposes only, (ii) may not be incorporated into any contract and (iii) does not constitute a commitment, promise or legal obligation to deliver any material, code, or functionality.  The development, release and timing of any features or functionality described for our products remains at our sole discretion.

3. Role of Ethernet in Optical Networks • Allocation of Optical Network Resources • Finer Control of Paths and Bandwidth • Integration between Optical & IP networks • Example: HOPI Project • You still need/want Ethernet: • Integration with LANs, end sites • Management / Subdivision of larger lambdas • Higher layer services

4. HOPI - Hybrid Optical Packet Infrastructure Fundamental Questions: How will the core Internet architecture evolve? What should the next generation Internet2 network infrastructure be? Examining a hybrid of shared IP packet switching and dynamically provisioned optical lambdas Modeling scaleable next-generation networks Force10 ParticipationInternet2 HOPI Project Internet2 Corporate Partner & HOPI project partner Provided five E600 switch/routers, deployed in Los Angeles, DC, Chicago, Seattle & New York

9. Control Plane Architecture • VLSR - The VLSR is a software suite which can be adapted to switching elements of various technologies. These switching elements can then act as a Label Switch Router (LSR) in Generalized MultiProtocol Label Switching (GMPLS) context • Includes protocols and functions such as Open Shortest Path First with Traffic Engineering extensions (OSPF-TE), Resource ReServation Protocol with Traffic Engineering extensions (RSVP-TE), Constrained Shortest Path First (CSPF) Path Computation, and switching element resource control and provisioning. • HOPI: Dynamic Control of VLANs (Virtual LANS) • Bandwidth Reservation for User Work (BRUW). BRUW is an adaptation of the CANARIE User-controlled Lightpath (UCLP) software to enable of MultiProtocol Label Switching (MPLS) Label-Switched Paths (LSPs) dynamic provisioning across IP routed infrastructures.
