Extreme Networks, Inc., together with its subsidiaries, (collectively referred to as Extreme or the Company and as we, us and our) is a leading provider of network infrastructure equipment for corporate, government, education and health care enterprises and metropolitan service providers. We were established in 1996 to address the issues caused by slow and expensive legacy networks. We endeavored to change the industry by replacing complex software-based routers with simple, fast, highly intelligent, hardware-based switches. The broad acceptance of this innovative, simplified approach to networking has enabled us to become an industry leader. Our ultimate goal is to realize our technology vision of Ethernet Everywhere – a unifying network strategy that uses proven Ethernet technology to simplify each element of the network. We believe our Ethernet Everywhere vision is the foundation for a future of easily deployable, highly scalable, comprehensively managed, ubiquitous bandwidth for networks, applications and users.

Our family of switching products provides significant performance improvements compared to legacy infrastructures, while enabling greater network flexibility and scalability, ease of use and a lower cost of ownership.

We have achieved these advantages by utilizing application specific integrated circuits, or ASICs, as well as merchant silicon in our products and by creating a common hardware, software and network management architecture for our products. In our products, the routing of network traffic, a function referred to as Layer 3 switching, is done primarily with our unique chipsets that provide faster processing of data than the CPU/software implementations used in many conventional networking products. We believe that our unique hardware and software designs can also provide a better price/performance ratio, resulting in a higher return on investment for our customers. Since chipsets are built for specific purposes, it allows for a lower cost structure with increased performance compared to other alternatives.

Businesses, governments, educational institutions and other organizations have become highly dependent on the Internet as their central communications infrastructure for providing connectivity for both internal and external communications. New computing applications, such as enterprise resource planning, or ERP, customer relationship management, or CRM, large enterprise data warehouses and sophisticated online transaction and other e-business applications, as well as the increased use of traditional applications such as e-mail and streaming media, require significant information technology resources for their support. The emergence of the desktop Internet browser as a standard user interface has enabled bandwidth-intensive applications that integrate voice, video and data to be deployed extensively throughout organizations. The steady rise in application sophistication and the associated bandwidth load demands a fast, flexible and scalable network infrastructure.

Networking environments can be segmented into local area networks, or LANs, wide area networks, or WANs, and metropolitan area

LANs. LANs are traditional networks designed for connecting users to many types of application servers, which may be held locally or remotely through either private WANs or through such systems as the Internet. The LAN consists of servers, clients, a network operating system and a communications link to connect the LAN to other networks and to the Internet. The LAN market as Extreme participates consists primarily of large and medium-sized enterprise customers.

WANs. WANs are communication networks that span across large geographic areas, such as counties, states or countries.

The addition of WAN support to ASIC-based or merchant silicon-based network switches permits Ethernet services to reach customers where integration with existing Synchronous Optical Network/Synchronous Digital Hierarchy, or SONET/SDH, infrastructure is required.

The WAN market includes local exchange carriers, multiple tenant/dwelling unit service providers, and Internet service providers, or ISPs, as primary customers, though an enterprise may also utilize a private WAN.

MANs. MANs are networks that link mid-sized geographic areas such as a city or an entire metropolitan area.

Due to wide deployment of Gigabit Ethernet, LANs have achieved geometric growth in bandwidth. Available bandwidth in WANs has also grown, as infrastructures are built out to accommodate the very rapid annual growth in Internet traffic. The MAN has emerged as the key link between the LAN and the WAN.

In recent years, the MAN has become a critical and dynamically evolving arena within the overall network infrastructure. In addition to steadily rising traffic load, the underlying network technologies, architectures and protocols are experiencing rapid change. The competitive landscape for MAN service providers is shifting, with an influx of new carriers who do not necessarily depend upon legacy infrastructure technologies such as SONET/SDH.

The MAN market includes both metropolitan service providers and municipalities that utilize a private MAN to connect multiple public facilities, such as city hall, fire departments, road and vehicle maintenance facilities, hospitals and emergency centers, social services and public libraries. The technologies and architectures associated with MANs are becoming popular within large and very large corporate enterprises, which can utilize private MANs to create a “super campus” network, connecting facilities spread over a city-size area.

Speed. Speed refers to the number of bits per second that can be transmitted across the network. Today’s network applications increasingly require speeds of up to 100 Mbps to the desktop. Therefore, the backbone and server connections that aggregate traffic from desktops require speeds in excess of 100 Mbps. “Wire-speed” refers to the ability of a network device to process an incoming data stream at the highest possible rate based on the full capability of the physical media, or wire without loss of packets. Wire-speed routing refers to the ability to perform Layer 3 switching at the maximum possible rate.

Bandwidth. Bandwidth refers to the volume of traffic that a network or a network device can handle before traffic is “blocked,” or unable to get through without interruption. When traffic was more predictable, the amount of traffic across a network link or through a network device generally grew in line with the number of devices connected to the network. With today’s data-intensive applications accessed in random patterns from both within and outside the core network, traffic can spike unpredictably, consuming significant bandwidth to the detriment of the network’s overall performance.

Network size. Network size refers to the number of users and servers that are connected to a network. Today’s networks must be capable of reliably connecting tens of thousands of users and servers while providing high performance and maximum application availability.

Quality of service. Quality of service refers to the ability to control the forwarding of traffic based upon its level of importance. Mission-critical enterprise applications, such as voice-over-IP, or VOIP, require specific performance minimums, while traffic such as general e-mail and Internet surfing may not be as critical. In addition to basic standards-based prioritization of traffic according to importance, enhanced quality of service also allocates bandwidth to specific applications based on a user-defined policy.

Several technology trends have enabled a new generation of networking equipment that can meet the four scalability dimensions required by today’s enterprises and service providers and the bandwidth-intensive, mission-critical applications on which they depend.

While many different technologies have been deployed in the LAN environment over the past 25 years, Ethernet has become the overwhelmingly dominant LAN technology. According to the Dell’Oro Group, an independent research organization, Ethernet is the technology used in over 99% of the LAN market in 2001 and over 800 million ports were shipped over the preceding ten-year period. Ethernet was evolved from its original 10 Mbps form into 100 Mbps Fast Ethernet, 1,000 Mbps, or “Gigabit” Ethernet and 10,000 Mbps or 10 Gigabit Ethernet, which became available during 2002. Today, Ethernet is moving beyond the LAN; Gigabit Ethernet and 10 Gigabit Ethernet represent a viable, high-capacity MAN backbone protocol, enabling broadband connections to be aggregated for transport across the core of the MAN.

With the widespread adoption of Ethernet and Internet Protocol, or IP, networking technologies, the need to support a multi-transport, multi-protocol environment is diminishing. As a result, simplified routing functionality can be embedded in fast, inexpensive chipsets to replace complex software/CPU designs used in conventional multi-protocol routers. The resulting device, called a Layer 3 switch, functions as a less expensive and significantly faster hardware-based router. Layer 3 switches operate at multi-gigabit speeds and can support large networks. While Layer 3 switching dramatically increases network performance, many products fail to realize the potential of this technology as a result of inconsistent hardware, software and management architectures.

Customers require a quality of service solution that supports both industry-standard prioritization and user-defined quality of service that maps business processes and policies to network performance. In addition, to simplify the network, customers need a family of interoperable devices that utilize a consistent hardware, software and management architecture.

We provide Ethernet networking solutions that meet the requirements of today’s enterprises and service providers by providing increased performance, scalability, policy-based quality of service, simplicity of use and lower cost of ownership. Our products share a common hardware, software and network management architecture, are based on industry-standard routing and network management protocols and offer advanced policy-based quality of service features. Our switches can be managed from any browser-equipped desktop PC or the Telnet applet supported in almost all operating systems. The Telnet applet allows access to the Command Line Interface, or CLI, which a system administrator may prefer to use.

Lower cost of ownership. Our products are generally less expensive than software-based routers, yet offer higher routing performance. We believe that by sharing a common hardware, software and management architecture, our products can substantially reduce the cost and complexity of network management and administration. This uniform architecture creates a simpler network infrastructure that leverages the resources businesses have invested in Ethernet/IP-based networks, thereby requiring fewer resources and less time to maintain the network.

Simplicity. Networks typically consist of many different technologies and types of equipment. This complexity often makes it expensive and difficult to effectively manage and expand networks. We meet these challenges by focusing on product consistency and simplicity. Our products share a common hardware, software and network management architecture and enable Layer 3 switching at wire-speed in each key area of the network. This allows customers to build an integrated network environment that utilizes a consistent feature set, performance and management capabilities.

Ease of use and implementation. Our products are designed to make networks easy to manage and administer, thereby reducing the overall cost of network ownership. Through the use of a standards-based design approach, our products can be readily integrated into existing networks. Customers can usually upgrade to our products without the need for additional training. Moreover, our ExtremeWare operating system software simplifies network management with a consistent, robust interface available in all product families.

High performance. Our products provide broadband Ethernet and IP services with the non-blocking, wire-speed performance of an ASIC-based or merchant silicon-based Layer 3 switching engine. With our switches, customers may achieve forwarding rates that are significantly faster than software-based routers.

Scalability. Our solutions offer customers the speed and bandwidth needed today — and the capability to scale their networks to

support demanding applications in the future—without the burden of additional training or software and system complexity. Customers who purchase standard Extreme products may later upgrade to advanced Layer 3 and Layer 4 features, such as server load balancing or intermediate-to-intermediate system routing protocol, or ISIS, as this upgraded functionality is designed into our products.

Quality of service. Our policy-based quality of service enables customers to prioritize mission-critical applications. We provide industry-leading tools for allocating network resources to specific applications. With our policy-based quality of service, customers can use a web-based interface to identify and control the forwarding of traffic from specific applications, in accordance with policies that the customers define. The quality of service functionality of our chipsets allows policy-based quality of service to be performed at wire-speed. In addition to providing prioritization, customers can allocate specified amounts of bandwidth to specific applications or users.

Our goal is to be the provider of the most effective applications and services infrastructure for large enterprises and service providers. We seek to provide our customers with a best-of-breed alternative to single-sourced, highly proprietary networking equipment from larger competitors. Key elements of our strategy include:

Provide simple, easy to use, high-performance, cost-effective switching solutions. We offer customers easy to use, powerful, cost-effective switching solutions that meet the specific demands of enterprises, and service and content providers. Our products provide customers with scalability from 10 Mbps Ethernet to 10 Gigabit Ethernet combined with the wire-speed, non-blocked routing of ASIC-based or merchant silicon-based Layer 3 switching. We intend to capitalize on our expertise in Ethernet, IP and hardware-based switching technologies to continuously develop new products that will meet the future requirements of a broad range of customers.

Expand market penetration. We continue to market our products to new customers in multiple market segments. The majority of our business is with enterprise customers, including those in government, education and the health care sectors, in addition to large commercial enterprises. Extreme has consistently focused on these markets since early in our history. Additionally, we aim to leverage our technology development, service and support and business infrastructure resources to address the metropolitan Ethernet market. These customers include ISPs, content providers and MAN service providers. While currently most of our service provider and MAN-related business is generated outside of the United States, we believe there is a long-term growth opportunity in the metropolitan Ethernet market on a worldwide basis. Once customers deploy our products in certain portions of their networks, we offer products for other areas. As additional products are deployed, customers obtain the increased benefits of our solution by simplifying their networks, extending policy-based quality of service and reducing costs of ownership, while increasing performance.

Extend switching technology leadership. Our technological leadership is based on proprietary technology embedded in our chipsets, the ExtremeWare operating system and network management and software. We intend to invest our engineering resources in chipsets, software and other development areas to create leading-edge technologies that will increase the performance and functionality of our products. We also intend to maintain our active role in industry standards committees such as the Institute for Electrical and Electronics Engineers, or IEEE, and the Internet Engineering Task Force, or IETF.

Leverage and expand multiple distribution channels. We distribute our products through select distributors and a large number of resellers. To quickly reach a broad, worldwide audience, we have more than 250 resellers in approximately 50 countries, including regional networking system resellers, network integrators and wholesale distributors. We maintain a field sales force to support our resellers and to focus on select strategic accounts. We are continually developing and refining our two-tier distribution channel strategy.

Provide high-quality customer service and support. We seek to enhance customer satisfaction and build customer loyalty through high-quality service and support. This includes a wide range of standard support programs that provide the level of service our customers require, from standard business hours to global 24-hour-a-day, 7-day-a-week, 365-day-a-year real-time response support. We intend to continue to enhance the ease of use of our products, and to invest in additional support services by increasing staff and adding new support programs for our distributors and resellers. We are committed to providing customer-driven product functionality through feedback from key prospects, consultants, channel partners and end-user customers.

We deliver effective application and services infrastructure for enterprises and service providers based on award-winning technology that combines simplicity, high performance, intelligence and a low cost of ownership. Our Layer 3 Summit, BlackDiamond and Alpine products share the same common hardware architecture and operating system, enabling businesses to build a network infrastructure

that is simple, easy to manage and scalable to meet the demands of future growth.

Our award-winning 2^nd Generation Inferno ASIC and 3^rd Generation Triumph chipsets are incorporated in all i-series products, including the BlackDiamond and Alpine. Inferno provides the core technology for high-end Summit switches.

We have also recently announced the 4^th Generation Networking Silicon System, or 4.G.N.S.S., also known by the code name “Genesis.” This technology provides very high performance capabilities for 10 Gigabit Ethernet and beyond as well as hardware-based support for advanced protocols such as IPv6 and MPLS. This technology also offers high levels of investment protection through the use of Extreme’s T-Flex technology that allows programmability of the chipset to allow changes in protocol support as new standards and protocols emerge.

The Summit family of switches is designed to meet the demanding requirements of Enterprise and metropolitan-Ethernet-based applications. All inferno-chipset-based Summit switches share a common switch architecture that provides scalability in four areas: speed, bandwidth, network size and policy-based quality of service. The Summit product family supports Gigabit and 10/100 Mbps aggregation for enterprise desktops and servers, large Internet data centers and broadband points of presence in MANs.

The Summit48i, Summit48si and the new Summit 200 series switches allow us to remain an industry leader in Layer 3 switching for the desktop. The Summit200-24 and Summit200-48 switches offer low entry costs for sophisticated Layer 2 and Layer 3 services, respectively, at the network edge. Additionally the Summit48i switch delivers an aggregation switching solution with physical and logical access, security and user mobility features at the edge.

The Summit 300 provides a unique set of capabilities as Extreme’s first Unified Access Architecture product supporting both wired and wireless connectivity. The Unified Access Architecture capabilities simplify the deployment of wireless but providing simple to install access points (Altitude 300) that are managed from a single point, reducing the cost of ownership and providing uniform approaches to security, authentication, quality of services and resiliency irrespective of the media connectivity type in use.

Other members of the Summit product line address server-switching constraints by providing switched Gigabit Ethernet ports and 100 Mbps links to servers, delivering required bandwidth between servers, and to clients on attached segments. In server farms and data centers, the Summit1i, Summit5i and Summit7i switches maximize server availability and performance by combining server load-balancing with wire-speed switching.

The BlackDiamond 6800 series delivers carrier-class scalability, redundancy and high reliability for core switching in high-density Ethernet/IP enterprise and service provider networks. These modular switches include the fault-tolerant features associated with mission-critical enterprise-class Layer 3 core switching, including redundant system management and switch fabric modules, hot-swappable modules and chassis components, load-sharing power supplies and management modules, up to eight 10 Mbps, 100 Mbps

or Gigabit aggregated links, dual software images and system configurations, spanning tree and multipath routing, and redundant router protocols for enhanced system and network reliability. The BlackDiamond switch can accommodate up to 16 I/O blades, including 10/100 Mbps, Gigabit and 10 Gigabit WAN interfaces.

The network core is the most critical point in the network, serving as the convergence point for the majority of network traffic, including desktop, segment and server traffic. Network core switching involves switching traffic from desktops, segments and servers within the network. Owing to the high-traffic nature of the network core, the critical elements in core switching include wire-speed Layer 3 switching, scalability, non-blocking hardware architecture, fault-tolerant mission-critical features, redundancy, and link aggregation. The ability to support a variety of high-density speeds and feeds and to accommodate an increasing number of high-capacity backbone connections is also important.

The BlackDiamond 6800 series is certified to be compliant with Network Equipment Building Systems, or NEBS Level 3, and offers an extensive range of modules, including legacy connections such as Packet-over-SONET, or PoS, OC-3 and OC-12, and Asynchronous Transfer Mode, or ATM, metropolitan connectivity through Multi-Protocol Label Switching, or MPLS, billing capabilities through Accounting and Routing Module, optical connectivity with Wave Division Multiplexing, or WDM, and industry-leading 10 Gigabit Ethernet connectivity.

This product line has been significantly enhanced through the addition of Extreme’s 3^rd Generation technology, Triumph, which adds market leading density/performance characteristics and sophisticated ingress based rate shaping as well as innovative streaming media replication. This is all fully hardware compatible with the existing “Inferno” chipset that has been deployed in this platform for several years ensuring excellent investment protection and continued low cost of ownership.

The Alpine 3800 series provides a simple, resilient broadband infrastructure for MANs, ISPs and mid-range enterprise networks. The Alpine 3800 series provides total Ethernet coverage with support for both standard category 5 and fiber optic media as well as first mile technologies that extend the reach of Ethernet-over-VDSL and legacy WAN technologies.

The Alpine 3800 series switches can be configured to scale from 8 to 56 Ethernet-over-VDSL ports. Even higher density can be achieved with a combination of Ethernet-over-VDSL and traditional copper or fiber Ethernet ports. The FM-8Vi module provides Ethernet-over-VDSL at 10 Mbps full-duplex on each port, up to 2,500 feet.

This product line has been significantly enhanced through the addition of Extreme’s 3^rd Generation technology, Triumph, which adds market leading density/performance characteristics and sophisticated ingress based rate shaping commensurate with the Alpine’s positioning as a low cost high density edge device for both Metro and Enterprise deployment. This is all fully hardware compatible with the existing “Inferno” chipset that has been deployed in this platform for several years ensuring excellent investment protection and continued low cost of ownership

ExtremeWare software is the embedded operating system software that is featured on all of our switches. It delivers the robust switching and routing protocol support, management, control and security needed on current enterprise and service provider networks. Its standards-based, multi-layer switching and policy-based Quality of Service, or QoS, give network managers the tools needed to optimize network capacity with consistent fault-tolerant behavior.

We conduct our sales and marketing activities on a worldwide basis through distributors, resellers and our field sales organization. A majority of our sales are currently made to partners in our distributor and reseller channels. The first tier consists of a limited number of independent distributors that sell primarily to resellers and end-user customers. The second tier of the distribution channel is

comprised of a large number of independent resellers that sell directly to end-user customers.

Distributors. We have established several key relationships with leading distributors in the electronics and computer networking industries. We intend to maintain these relationships with distributors who may offer products or distribution channels that complement our own channels. Each of our distributors resells our products to reseller and end-user customers. The distributors enhance our ability to sell and provide support to end-user customers, especially global accounts, who may benefit from the broad service and product fulfillment capabilities offered by these distributors. One distributor accounted for 11%, 15% and 16% of our net revenue in fiscal 2003, fiscal 2002 and fiscal 2001, respectively. Distributors are generally given privileges to return a portion of inventory and participate in various cooperative marketing programs to promote the sale of our products and services. We defer recognition of revenue on all sales to these distributors until the distributors sell the product, as evidenced by a monthly sales-out report that the distributors provide to us. (See “Revenue Recognition” in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.)

Value-Added Resellers. We have entered into agreements to sell our products through more than 250 resellers in approximately 50 countries. Our value-added resellers include regional networking system resellers, resellers who focus on specific vertical markets, network integrators and wholesale distributors. We provide training and support to our resellers and our resellers generally provide the first level of support to end users of our products. Our relationships with resellers are generally on a non-exclusive basis. Our resellers are not given privileges to return inventory and do not automatically participate in any cooperative marketing programs. We generally recognize product revenue from our end-user and reseller customers at the time of shipment, provided that persuasive evidence of an arrangement exists, the price of the product is fixed or determinable and collection of the sales proceeds is reasonably assured. When significant obligations or contingencies remain after products are delivered, such as installation or customer acceptance, revenue and related costs are deferred until such obligations or contingencies are satisfied. (See “Revenue Recognition” in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.)

Field sales. We have trained our field sales organization to support and develop leads for our resellers and to establish and maintain a limited number of key accounts and strategic customers. To support these objectives, our field sales force:

As of June 29, 2003, our worldwide sales and marketing organization consisted of 335 individuals, including directors, managers, sales representatives, and technical and administrative support personnel. We have domestic sales offices located in 21 states and international sales offices located in 25 countries.

International sales are an important portion of our business. In fiscal 2003, sales to customers outside of the United States accounted for 60% of our consolidated net revenue, compared to 67% in fiscal 2002 and 57% in fiscal 2001. These sales are conducted primarily through foreign-based distributors and resellers managed by our worldwide sales organization, in addition to direct sales to end-user customers, including large global accounts. The primary markets for sales outside of the United States include the countries in Western Europe and Japan. Although not a significant component of total revenues to date, we have also achieved sales growth in the People’s Republic of China and other countries throughout the Asia-Pacific region.

We have a number of marketing programs to support the sale and distribution of our products and to inform existing and potential customers and our distributors and resellers about the features and performance of our products. Our marketing efforts include participation in industry tradeshows, technical conferences and technology seminars, preparation of competitive analyses, sales training, publication of technical and educational articles in industry journals, a publicly available website, web-based training courses, advertising and public relations. In addition, we are developing e-commerce processes and systems for our resellers, distributors and end-user customers. We also submit our products for independent product testing and evaluation.

Our products are often sold on the basis of standard purchase orders that are cancelable prior to shipment without significant penalties. In addition, purchase orders are subject to changes in quantities of products and delivery schedules in order to reflect changes in customer requirements and manufacturing capacity. Our business is characterized by seasonal variability in demand and short lead-time orders and delivery schedules. Actual shipments depend on the then-current capacity of our contract manufacturers and the availability of materials and components from our vendors. We believe that only a small portion of our order backlog is non-cancelable and that the dollar amount associated with the non-cancelable portion is immaterial. Accordingly, we do not believe that backlog at any given time is a meaningful indicator of future revenue.

We offer modular and comprehensive ExtremeWorks service solutions to help protect our customers’ network investments and support their business goals. The markets we address, including enterprises and service providers, all seek higher reliability and maximum uptime. Our goal is to serve as a knowledgeable and experienced service partner who can tailor service solutions to meet the specific business needs of our customers. Accordingly, in fiscal year 2002 we entered into a global services agreement with International Business Machines, Inc. for the provision of on-site hardware support to customers. Expenses related to this agreement are recorded in services cost of revenue on our consolidated statement of operations. We also maintain a relationship with Solectron Corporation for the handling of product returns and repairs covered by our warranty and service contracts in various locations worldwide. Warranty expenses related to this relationship are recorded in product cost of revenue on our consolidated statement of operations. Support contract expenses related to this relationship are recorded in services cost of revenue on our consolidated statement of operations.

ExtremeWorks Professional Services. We specialize in providing solutions and consultative services to improve network productivity in all phases of the network lifecycle –planning, design, implementation, operation and optimization management. The professional services include customized and packaged consulting services that assist customers in meeting their objectives for applications support, uptime and cost control. Our network architects develop and execute customized hardware deployment plans to meet individualized network strategies. These activities include the management and coordination of the design and network configuration, resource planning, staging, logistics, migration and deployment. We also provide customized training and operational change management documentation to assist customers in the transition and sustaining of their networks.

ExtremeWorks Support Programs. Our support programs are designed to support a broad range of customer service requirements. We meet the service requirements of all our customers through Technical Assistance Centers, or TACs, located in Santa Clara, California, Utrecht, Holland, and Tokyo, Japan. Our technical engineers assist in diagnosing and troubleshooting technical issues regarding customer networks. This is part of our effort to ensure maximum network uptime and performance. Regional systems engineers serve as on-site engineering resources to provide consultative support and advice for network operation on an as needed basis. Development

engineers work with the TACs to resolve product functionality issues specific to each customer.

We utilize the Internet to distribute and obtain information from our customer base as an integral part of our service solution. This allows us to keep customers informed of the latest updates and developments at Extreme Networks, and contains up-to-date information and technical documentation enabling customers to research issues and find answers to technical questions. Special features include a TAC database to obtain troubleshooting assistance and information for configuring software, diagnosing hardware, and researching network issues. On-site support services are available in most locations worldwide for customers who require a more comprehensive level of service and support.

ExtremeWorks Education. Leveraging our Authorized Training Partner strategy, Extreme Networks licenses partners to provide education through certified technical experts that teach classes dealing with all of our products. The classes cover a wide range of topics such as installation, configuration, operation, management and optimization – providing customers with the necessary knowledge and experience to successfully deploy and manage our products in various networking environments. Classes are scheduled and available at numerous locations worldwide.

We outsource the majority of our manufacturing and supply chain management operations as part of our strategy to maintain global manufacturing capabilities and to reduce costs. We conduct quality assurance, manufacturing engineering, document control and test development at our main campus in Santa Clara, California. This approach enables us to reduce fixed costs and to flexibly respond to changes in market demand.

We have strategic partnerships with two contract manufacturers – Flextronics International, Ltd. for the manufacture of our products in San Jose, California and Guadalajara, Mexico and Plexus Corp. for the manufacture of our products in Nampa, Idaho and Penang, Malaysia. Each of these vendor’s manufacturing processes and procedures are ISO 9002 certified. Our commitments with our contract manufacturers are currently on a purchase order basis. We are currently negotiating a contract with Flextronics that will enhance and formalize our arrangement with them. We design and develop the key components of our products, including ASICs and printed circuit boards. We determine the components that are incorporated in our products and select the appropriate suppliers of such components. Our contract manufacturers utilize automated testing equipment to perform product testing and burn-in with specified tests. Together with our contract manufacturers, we rely upon comprehensive inspection testing and statistical process controls to assure the quality and reliability of our products. We intend to regularly introduce new products and product enhancements that will require us to rapidly achieve volume production by coordinating our efforts with those of our suppliers and contract manufacturers.

Although we use standard parts and components for our products where it is appropriate, we currently purchase several key components used in the manufacture of our products from single or limited sources. Our principal single-source components include:

Purchase commitments with our single- or limited-source suppliers are generally on a purchase order basis. (See “Purchase Commitments” in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.) A number of vendors supply standard product integrated circuits and microprocessors for our products. Any interruption or delay in the supply of any of these components, or the inability to procure these components from alternate sources at acceptable prices and within a reasonable time, may have a material adverse effect on our business, operating results and financial condition. Qualifying additional suppliers can be time-consuming and expensive and may increase the likelihood of errors.

We use our forecast of expected demand to determine our material requirements. Lead times for materials and components vary significantly, and depend on factors such as the specific supplier, contract terms and demand for a component at a given time. We order many of our materials and components on an indirect basis through our contract manufacturers.

The success of our products to date is due in large part to our focus on research and development. We believe that continued success in the marketplace will depend on our ability to develop new and enhanced products employing leading-edge technology. Accordingly, we are undertaking development efforts with an emphasis on increasing the reliability, performance and features of our family of products, and designing innovative products to reduce the overall network operating costs of customers.

Our product development activities focus on solving the needs of enterprises, service providers and metropolitan area network markets. Current activities include the continuing development of a next-generation chipset aimed at extending the capabilities of our products. Our ongoing research activities cover a broad range of areas, including, in particular, 10 Gigabit Ethernet and SONET, metropolitan network and Internet routing software, ASIC design, network management software, broadband access equipment, wireless networking equipment and content networking devices.

Our products have been designed with a uniform system architecture for all products, that expedites our design and development cycle as well as the time to market for new products and features. We have utilized this design approach to develop and introduce new products and enhancements and we intend to continue with this simplified approach to architectural design to develop and introduce additional products and enhancements in the future.

As of June 29, 2003, our research and development organization consisted of 244 individuals. Our expenditures for research and development in fiscal 2003, fiscal 2002 and fiscal 2001 were $58.0 million, $61.5 million and $57.9 million, respectively. These amounts do not include in-process research and development charges in the amount of $30.2 million related to our acquisitions in fiscal 2001.

The market for switches is part of the broader market for networking equipment, which is dominated by a few large companies, particularly Cisco Systems. Each of these companies has introduced, or has announced its intention to develop, switches that are or may be competitive with our products, such as the Catalyst 6000 family of switches offered by Cisco Systems. In addition, there are a number of large telecommunications equipment providers, including Alcatel and Nortel Networks, which have entered the market for network equipment, particularly through acquisitions of public and privately held companies. We expect to face increased competition, particularly price competition, from these and other telecommunications equipment providers. We also compete with other public and private companies that offer switching solutions, including Enterasys Networks, Foundry Networks, Inc., Huawei Technologies, Riverstone Networks, 3Com Corporation and Dell Computer Corporation. These vendors offer products with functionality similar to our products or provide alternative network solutions. Current and potential competitors have established or may establish cooperative relationships among themselves or with third parties to develop and offer competitive products. Furthermore, we compete with numerous companies that offer routers and other technologies and devices that traditionally have managed the flow of traffic on the enterprise or metropolitan area networks.

Many of our current and potential competitors have longer operating histories and substantially greater financial, technical, sales, marketing and other resources, as well as greater name recognition and a larger installed customer base, than we do. As a result, these competitors are able to devote greater resources to the development, promotion, sale and support of their products. In addition, competitors with a large installed customer base may have a significant competitive advantage over us. We have encountered, and expect to continue to encounter, many potential customers who are confident in and committed to the product offerings of our principal competitors, including Cisco Systems. Accordingly, these potential customers may not consider or evaluate our products. When such potential customers have considered or evaluated our products, we have in the past lost, and expect in the future to lose, sales to some of these customers as large competitors have offered significant price discounts to secure these sales.

We believe the principal competitive factors in the network switching market are:

We believe that we compete favorably with our competitors with respect to each of the foregoing factors. However, because many of our existing and potential competitors have longer operating histories, greater name recognition, larger customer bases and substantially greater financial, technical, sales, marketing and other resources, they may have larger distribution channels, stronger brand names, access to more customers and a larger installed customer base than we do. Such competitors may, among other things, be able to undertake more extensive marketing campaigns, adopt more aggressive pricing policies and make more attractive offers to distribution partners than we can. To remain competitive, we believe that we must, among other things, invest significant resources in developing new products and enhancing our current products and maintain customer satisfaction worldwide. If we fail to do so, our products will not compete favorably with those of our competitors and that may have a material adverse effect on our business.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. Based on our commitment to build a patent portfolio, we have in process a number of patent applications relating to our proprietary technology. We have filed patent applications in selected countries abroad as deemed appropriate. There can be no assurance that these applications will be approved, that any issued patents will protect our intellectual property, or that third parties will not challenge these patents or applications. Furthermore, there can be no assurance that others will not independently develop similar or competing technology or design around any patents that we may obtain. With respect to trademarks, we have fourteen registered trademarks in the United States. In addition, we have a significant number of pending trademark applications and registered trademarks abroad.

We enter into confidentiality or license agreements with our employees, consultants and corporate partners, and control access to, and distribution of, our software, documentation and other proprietary information. In addition, we provide our software products to end-user customers primarily under “shrink-wrap” license agreements included within the packaged software. These agreements are not negotiated with or signed by the licensee, and thus these agreements may not be enforceable in some jurisdictions. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. There can be no assurance that these precautions will prevent misappropriation or infringement of our intellectual property. Monitoring unauthorized use of our products is difficult, and we cannot be certain that the steps we have taken will prevent misappropriation of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States.

The networking industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In particular, leading companies in the data communications and networking markets have extensive patent portfolios with respect to networking technology. From time to time, third parties, including these leading companies, have asserted and may assert patent, copyright, trademark and other intellectual property rights against us in regard to technologies and related standards that we consider to be important. We expect to increasingly be subject to infringement claims asserted by third parties as the numbers of products and competitors in the market for network switches grow and product functionality overlaps.

As detailed below under “Legal Proceedings,” we are currently engaged in litigation with Lucent Technologies, Inc. (“Lucent”). Lucent is asserting claims that allege infringement of certain patent rights, against which we are defending vigorously, but we cannot assure you that we will prevail in this litigation. In addition to the litigation with Lucent, we have been in communication with a number of major technology companies that assert certain of our products require a license under a number of their patents. These parties have indicated a willingness to grant us a royalty-bearing, non-exclusive license under the identified patents, as well as other patents that we may require. We are currently reviewing the identified patents to determine whether we consider a license necessary. However, there can be no assurance that these licenses would be obtainable on commercially acceptable terms.

In the future, we may determine it is necessary to initiate claims or litigation against third parties for infringement of our proprietary rights. Any such claims, whether asserted by us or a third party against us, could be time-consuming, result in costly litigation and diversion of technical and management personnel or require us to develop non-infringing technology or enter into royalty or licensing agreements. Royalty-bearing license agreements, if required, may not be available on acceptable terms, if at all. In the event a third party is successful in a claim of infringement, our failure or inability to develop non-infringing technology or license the proprietary rights on a timely basis may have a material, adverse effect on our business, operating results and financial condition.

As of June 29, 2003, we employed 890 people, including 335 in sales and marketing, 244 in engineering, 92 in operations, 105 in customer support and service, and 114 in finance and administration. We have never had a work stoppage and no personnel are represented under collective bargaining agreements. We consider our employee relations to be good.

We believe that our future success depends on our continued ability to attract, integrate, retain, train and motivate highly qualified personnel, and upon the continued service of our senior management and key personnel. None of our personnel is bound by an employment agreement. The market for qualified personnel is competitive, particularly in the San Francisco Bay Area, where our headquarters is located. At times, we have experienced difficulties in attracting new personnel.

We were incorporated in California in May 1996 and reincorporated in Delaware in March 1999. Our corporate headquarters are located at 3585 Monroe Street, Santa Clara, CA 95051 and our telephone number is (408) 579-2800. Our website can be found at www.extremenetworks.com. Investors can obtain copies of our SEC filings from this website free of charge, or on the SEC’s website at www.sec.gov.

Our principal administrative, sales, marketing and research and development facilities are located in Santa Clara, California. We also lease office space and executive suites in various other geographic locations domestically and internationally for sales and service personnel and engineering operations. Our aggregate lease expense for fiscal 2003 was approximately $6.3 million, net of sublease income of approximately $0.1 million. We believe our current facilities will adequately meet our growth needs for the foreseeable future, and we are actively engaged in efforts to sublease excess space we acquired in prior years to meet the anticipated growth at that time.

On May 27, 2003, Lucent filed suit against Extreme Networks and Foundry Networks, Inc. (“Foundry”) in the United States District Court for the District of Delaware, Civil Action No. 03-508. The complaint alleges willful infringement of U.S. Patent Nos. 4,769,810, 4,769,811, 4,914,650, 4,922,486 and 5,245,607 and seeks a judgment: (a) determining that we have willfully infringed each of the five patents; (b) determining that Foundry has willfully infringed four of the five patents; (c) permanently enjoining us from infringement, inducement of infringement and contributory infringement of each of the five patents; (d) permanently enjoining Foundry from infringement, inducement of infringement and contributory infringement of four of the five patents; and (e) awarding Lucent unspecified amounts of trebled damages, together with expenses, costs and attorneys’ fees.

We answered Lucent’s complaint on July 16, 2003, denying that we have infringed any of the five patents and also asserting various affirmative defenses and counterclaims that seek judgment: (a) that Lucent’s complaint be dismissed and Lucent be denied all requested relief; (b) declaring that we do not infringe, induce infringement or contribute to the infringement of any valid and enforceable claim of the five patents, (c) that each of the five patents be declared invalid; (d) finding the case exceptional within the definition of 35 U.S.C. § 285; and (e) that Lucent pay our attorneys’ fees and costs.

Discovery is proceeding. As set forth above, we have denied Lucent’s allegations and intend to defend the action vigorously. We cannot assure you, however, that we will prevail in this litigation, which could have a material, adverse effect on our financial position, results of operations and cash flows in the future.

Beginning on July 6, 2001, purported securities fraud class action complaints were filed in the United States District Court for the Southern District of New York. The cases were consolidated and the litigation is now captioned as In re Extreme Networks, Inc. Initial Public Offering Securities Litigation, Civ. No. 01-6143 (SAS) (S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, 21 MC 92 (SAS) (S.D.N.Y.).

The operative amended complaint is brought purportedly on behalf of all persons who purchased Extreme Networks’ common stock from April 8, 1999 through December 6, 2000. It names as defendants Extreme Networks; six of our present and former officers and/or directors, including our CEO (the “Extreme Networks Defendants”); and several investment banking firms that served as underwriters of our initial public offering and October 1999 secondary offering. Subsequently, plaintiffs and one of the individual defendants stipulated to a dismissal of that defendant without prejudice. The complaint alleges liability under Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, on the grounds that the registration statement for the offerings did not disclose that: (1) the underwriters had agreed to allow certain customers to purchase shares in the offerings in exchange for excess commissions paid to the underwriters; and (2) the underwriters had arranged for certain customers to purchase additional shares in the aftermarket at predetermined prices. The Securities Act allegations against the Extreme Networks Defendants are made as to the secondary offering only. The amended complaint also alleges that false analyst reports were issued. No specific damages are claimed.

Similar allegations were made in other lawsuits challenging over 300 other initial public offerings and follow-on offerings conducted in 1999 and 2000. The cases were consolidated for pretrial purposes. On February 19, 2003, the Court ruled on all defendants’ motions to dismiss. The Court denied the motions to dismiss the claims in our case under the Securities Act of 1933. The Court denied the motion to dismiss the claim under Section 10(a) of the Securities Exchange Act of 1934 against Extreme Networks and 184 other issuer defendants, on the basis that the complaints alleged that the respective issuers had acquired companies or conducted follow-on offerings after their initial public offerings. The Court denied the motion to dismiss the claims under Section 10(a) and 20(a) of the Securities Exchange Act of 1934 against the remaining Extreme Networks Defendants and 59 other individual defendants, on the basis that the respective amended complaints alleged that the individuals sold stock.

We have decided to accept a settlement proposal presented to all issuer defendants. In this settlement, plaintiffs will dismiss and release all claims against the Extreme Network Defendants, in exchange for a contingent payment by the insurance companies collectively responsible for insuring the issuers in all of the IPO cases, and for the assignment or surrender of control of certain claims we may have against the underwriters. The Extreme Networks Defendants will not be required to make any cash payments in the settlement, unless the pro rata amount paid by the insurers in the settlement exceeds the amount of the insurance coverage, a circumstance which we do not believe will occur. The settlement will require approval of the Court, which cannot be assured, after class members are given the opportunity to object to the settlement or opt out of the settlement. If the settlement is not approved, we cannot assure you that we will prevail in the lawsuit. Failure to prevail could have a material adverse effect on our consolidated financial position, results of operations and cash flows in the future.

Other than the proceedings stated above, we are not aware of any pending legal proceedings against us that, individually or in the aggregate, would have a material adverse effect on our business, operating results or financial condition. We may in the future be party to litigation arising in the course of our business, including claims that we allegedly infringe third-party trademarks and other intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

We currently intend to retain future earnings for the development of our business.

The following table summarizes our equity compensation plans as of June 29, 2003:

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our significant accounting policies are more fully described in Note 2 of Notes to Consolidated Financial Statements included in this Form 10-K. The preparation of our consolidated financial statements in accordance with generally accepted accounting principles requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the period reported. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. We base our estimates and judgments on historical experience, market trends and other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. We believe the critical accounting policies stated below, among others, affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

We derive the majority of our revenue from sales of our stackable and chassis-based networking equipment, with the remaining revenue generated from service fees relating to the maintenance and installation of, and training on, our products. Our revenue recognition policy follows SEC Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements. We generally recognize product revenue from our end-user and reseller customers at the time of shipment, provided that persuasive evidence of an arrangement exists, the price of the product is fixed or determinable and collection of the sales proceeds is reasonably assured. When significant obligations or contingencies remain after products are delivered, such as installation or customer acceptance, revenue and related costs are deferred until such obligations or contingencies are satisfied. Revenue from service obligations under maintenance contracts is deferred and recognized on a straight-line basis over the contractual period, which typically range from one to five years. When we provide a combination of products and services to customers, revenue is allocated based on the relative fair values.

We make certain sales to partners in two-tier distribution channels. The first tier consists of a limited number of independent distributors that sell primarily to resellers and, on occasion, to end-user customers. Under specified conditions, we grant these distributors the right to return a portion of unsold inventory to us for the purpose of stock rotation. Therefore, we defer recognition of revenue on all sales to these distributors until the distributors sell the product, as evidenced by a monthly sales-out report that the distributors provide to us. Our decision to defer revenue on these sales until the distributors sell the product required judgment. Others, in similar circumstances, may conclude it is appropriate to recognize revenue on such sales upon delivery to the distributor. The second tier of the distribution channel consists of a large number of third-party resellers that sell directly to end-users and are not granted return privileges, except for defective products.

We provide an allowance for sales returns based on our historical returns, analysis of credit memo data and our return policies. The allowance is charged to net revenue in the accompanying consolidated statements of operations. If the historical data used by us to calculate the estimated sales returns and allowances does not properly reflect future levels of product returns, these estimates would have to be modified, thus resulting in an impact to net revenue.

The networking industry is characterized by rapid technological change, frequent new product introductions, changes in customer requirements and evolving industry standards. We perform a detailed assessment of inventory at each balance sheet date, which includes a review of, among other factors, demand requirements, product lifecycle and product development plans and quality issues. Based on this analysis, we record adjustments, when appropriate, to reflect inventory at net realizable value. In fiscal 2003 and fiscal 2002, demand for our products was adversely affected by the downturn in the global economy and reduced telecommunications and infrastructure capital spending, particularly in the United States. Although we make every effort to ensure the accuracy of our forecasts of product demand, any significant unanticipated changes in demand or technological developments would significantly impact the value of our inventory and our reported operating results. In the future, if we find that our estimates are too optimistic and we determine that our inventory needs to be written down, we will be required to recognize such costs in our cost of revenue at the time of such determination. Conversely, if we find our estimates are too pessimistic and we subsequently sell product that has previously been written down, our operating margin in that period will be unusually favorable.

Networking products can contain undetected hardware or software errors when new products or new versions or updates of existing

products are released to the marketplace. We have experienced such errors in connection with products and product upgrades. Our standard hardware warranty period is 12 months from the date of shipment to end-users and 14 months from the date of shipment to channel partners, which include resellers and distributors. Upon shipment of products to our customers, including both end-users and channel partners, we estimate expenses for the cost to repair or replace products that may be returned under warranty and accrue a liability for this amount.

The determination of our warranty requirements is based on our actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. We estimate and adjust these accruals at each balance sheet date in accordance with changes in these factors. While we believe that our warranty accrual is adequate and that the judgments applied in calculating this accrual are appropriate, the assumptions used are based on estimates and these estimated amounts could differ materially from our actual warranty expenses in the future.

We continually monitor and evaluate the collectibility of our trade receivables based on a combination of factors. We record specific allowances for bad debts in general and administrative expense when we become aware of a specific customer’s inability to meet its financial obligation to us, such as in the case of bankruptcy filings or deterioration of financial position. Estimates are used in determining our allowances for all other customers based on factors such as current trends in the length of time the receivables are past due and historical collection experience. We mitigate some collection risk by requiring most of our customers in the Asia-Pacific region, excluding Japan, to pay cash in advance or secure letters of credit when placing an order with us.

We recognize deferred tax assets and liabilities based on the differences between the financial statement carrying amounts and the tax bases of assets and liabilities. Significant management judgment is required in determining our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We make an assessment of the likelihood that our net deferred tax assets will be recovered from future taxable income, and to the extent that recovery is not believed to be likely, a valuation allowance is established. During fiscal 2003, we established a full valuation allowance for our net deferred tax assets.

The valuation allowance was calculated in accordance with the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 109, Accounting for Income Taxes (“SFAS 109”), which requires an assessment of both negative and positive evidence when measuring the need for a valuation allowance. In accordance with SFAS 109, evidence, such as operating results during the most recent three-year period, is given more weight than our expectations of future profitability, which are inherently uncertain. Our net losses in recent periods represented sufficient negative evidence to require a full valuation allowance against our net deferred tax assets under SFAS 109. This valuation allowance will be evaluated periodically and can be reversed partially or totally if business results have sufficiently improved to support realization of our deferred tax assets.

We currently have arrangements with two contract manufacturers and other suppliers for the manufacture of our products. Our arrangements allow them to procure long lead-time component inventory on our behalf based upon a rolling production forecast provided by us. We are obligated to the purchase of long lead-time component inventory that our contract manufacturers procure in accordance with the forecast, unless we give notice of order cancellation outside of applicable component lead-times. As of June 29, 2003, we were committed to purchase approximately $22.8 million of such inventory during the first quarter of fiscal 2004. If actual demand of our products is below these projections, we may have excess inventory as a result of our purchase commitments of long lead-time components with our contract manufacturers. As a consequence, we may then need to record a charge to cost of revenue to reflect the impact of such excess purchase commitments.

We must test goodwill annually for impairment using a two-step process as required by SFAS No. 142, Goodwill and Other Intangible Assets. In addition, in certain circumstances, we must assess whether goodwill should be tested for impairment between annual tests. Intangible assets with definite useful lives and other long-lived assets must be tested for impairment in accordance with SFAS No. 144, Accounting for Impairment of Disposal of Long-Lived Assets. We assess the carrying value of long-lived assets, whenever events or changes in circumstances indicate that the carrying value of these long-lived assets may not be recoverable. Factors we consider important which could trigger an impairment review include significant under-performance relative to the expected historical or projected future operating results; significant changes in the manner of use of the assets; significant negative industry or economic trends and significant changes in Extreme Networks’ market capitalization relative to net book value. Any changes in key assumptions

about the business or prospects, or changes in market conditions or other externalities, could result in an impairment charge and such a charge could have a material adverse affect on our consolidated results of operations.

We are currently involved in various claims and legal proceedings. Periodically, we review the status of each significant matter and assess our potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, we accrue a liability for the estimated loss. Because of uncertainties related to these matters, accruals, if any, are based only on the most current and dependable information available at any given time. As additional information becomes available, we may reassess the potential liability from pending claims and litigation and the probability of claims being successfully asserted against us. As a result, we may revise our estimates related to these pending claims and litigation. Such revisions in the estimates of the potential liabilities could have a material impact on our consolidated results of operations, financial position and cash flows in the future. For further detail, see Note 5 of Notes to Consolidated Financial Statements for a description of legal proceedings.

Net revenue was $363.3 million in fiscal 2003, $441.6 million in fiscal 2002 and $491.2 million in fiscal 2001, representing a decrease of 17.7% in fiscal 2003 from fiscal 2002 and a decrease of 10.1% in fiscal 2002 from fiscal 2001. As a percentage of total net revenue, service revenue was 10.6% in fiscal 2003, 7.8% in fiscal 2002 and 5.6% in fiscal 2001. The decrease in net revenue in fiscal 2003 compared to fiscal 2002 was primarily due to a decline in revenue in Japan. The decrease in net revenue in fiscal 2002 compared to fiscal 2001 was primarily due to a decline in revenue in the United States, as our business was negatively impacted by the cautious purchasing behavior of customers in the difficult economic environment during fiscal 2002, offset in part by an increase in revenue from service provider customers in Japan.

Sales outside of the United States accounted for 60%, 67% and 57% of net revenue in fiscal 2003, fiscal 2002 and fiscal 2001, respectively. The decrease in net revenue outside the United States in fiscal 2003 compared to fiscal 2002 was due to a reduction of sales in Japan. The decrease in United States sales in fiscal 2002 compared to fiscal 2001 as a percentage of total sales was primarily attributable to reduced sales within the United States in the first half of 2002 as a result of the events of September 11, 2001. Sales within the United States in the second half of fiscal 2002 steadily increased as a percentage of total sales. We expect that export sales will continue to represent a significant portion of net revenue, although export sales may decline as a percentage of net revenue. All sales transactions are currently denominated in United States dollars.

During fiscal 2003 and fiscal 2002, the United States economy experienced a prolonged downturn for information technology products generally. We believe this phenomenon has adversely affected demand for our products and has made it increasingly more difficult to accurately forecast future production requirements. Our revenue for the first quarter of fiscal 2004 could be adversely impacted by the continuing weakness and uncertainty in the economies of the United States and other industrialized countries. While we expect this economic downturn to continue for some time, we cannot predict the extent, severity or length of this economic downturn in the United States or in the other geographic regions where we currently sell our products. Further, we expect that our revenue during fiscal 2004 will be significantly affected by the timing and success of the introduction of new products during the fiscal year.

We are experiencing some erosion of average selling prices of our products due to a number of factors, including competitive pricing pressures, promotional pricing and rapid technological change. Our revenue is derived primarily from sales of our Summit, BlackDiamond and Alpine product families and fees for services relating to the installation and maintenance of, and training on, our products. The level of sales to any customer may vary from period to period; however, we expect that significant customer concentration will continue for the foreseeable future. One customer, who is a distributor of our products, accounted for 11%, 15% and 16% of our net revenue in fiscal 2003, fiscal 2002 and fiscal 2001, respectively.

Cost of revenue includes costs of raw materials, direct labor, manufacturing overhead and amounts paid to third-party contract manufacturers, service operations and other costs related to warranty and contractual obligations. Gross margin was $150.4 million in fiscal 2003, $184.0 million in fiscal 2002 and $192.2 million in fiscal 2001, representing a decrease of 18.3% in fiscal 2003 from fiscal 2002 and a decrease of 4.3% in fiscal 2002 from fiscal 2001. These decreases were primarily due to the related decreases in revenue. As a percentage of net revenue, gross margin was 41.4% in fiscal 2003, 41.7% in fiscal 2002 and 39.1% in fiscal year 2001. The increase in gross margin percent in fiscal 2002 over fiscal 2001 resulted primarily from a shift in product mix and a decrease in the net

charges related to contract manufacturers and other costs associated with the carrying value of inventory, including a benefit to cost of revenue in fiscal 2002 of $4.8 million relating to products sold that were written off in fiscal 2001. This increase in gross margin in fiscal 2002 over fiscal 2001 was adversely affected by a significant increase in warranty expense. During fiscal 2002 we experienced a higher than normal rate of warranty expense due to problems with various component parts within our products and our election, in some cases, to address those problems by replacing such products with new rather than refurbished replacements. We intend to reduce these expenses in the future, however our gross margin will continue to be adversely affected until we have completed the implementation of operational changes designed to reduce these expenses.

As a result of our increased service revenue as a percentage of net revenue for fiscal 2003, we have separately reported product and service gross margin. The fiscal 2003 service gross margin calculation includes all service related expenses. Gross margin for fiscal 2002 and fiscal 2001 is presented in total since we do not have records that detail product and service cost of revenue in separate categories. Furthermore, in the past, some service related expenses were included in operating expenses as part of the line item entitled sales, marketing and service expense. For fiscal 2003 and going forward, our new ERP system that was implemented at the beginning of fiscal 2003 enables us to record cost of product and service revenue in separate detail. We were able to identify the service expenses that had previously been included in operating expenses and, therefore, our fiscal 2002 and fiscal 2001 results reflect the reclassification of $23.1 million and $17.8 million, respectively, from operating expenses to cost of services revenue. Such amounts represented 5.3% and 5.7% of previously reported operating expenses for fiscal 2002 and fiscal 2001, respectively.

Our service line of business had a negative gross margin in fiscal 2003 due primarily to a number of programs that we implemented to improve service delivery productivity and enhance customer satisfaction. We have developed and implemented plans to improve our service gross margin going forward. These plans include increasing service revenue and reducing service infrastructure expenses and service outsourcing expenses. While we expect our service line of business to generate positive gross margin as a result of these plans we cannot predict the success or timing of the impact of these plans.

Inventory purchases and commitments are based upon our forecast of future sales. To mitigate the component supply constraints that existed in fiscal 2001, we built inventory levels for certain components with long lead times and entered into long-term commitments with our suppliers for certain components. Due to a sudden and significant decrease in demand for our products that became apparent in the third quarter of fiscal 2001, inventory levels, including non-cancelable purchase commitments, exceeded our requirements based on our forecast of expected demand. We recorded a provision for excess and obsolete inventory, including non-cancelable purchase commitments of $7.8 million, totaling $39.2 million in the third quarter of fiscal 2001. The $31.4 million excess inventory charge was calculated based on the inventory levels in excess of our forecast of expected demand for each product. Based on our then determined future demand forecast, we did not, and we currently do not, anticipate that the excess inventory subject to these provisions will be used at a later date. Furthermore, we may be required to take additional write-downs in the future related to excess inventory.

Our product and service gross margins are variable and dependent on many factors, some of which are outside of our control. Some of the primary factors affecting gross margin include demand for our products, changes in our pricing policies and those of our competitors, and the mix of products sold. Our gross margin may be adversely affected by increases in material or labor costs, increases in warranty expense or the cost of providing services under extended service contracts, heightened price competition, obsolescence charges and higher inventory balances. In addition, our gross margin may fluctuate due to the mix of distribution channels through which our products are sold, including the effects of our two-tier distribution model. Any significant decline in sales to our resellers, distributors or end-user customers, or the loss of any of our key resellers, distributors or end-user customers could have a material adverse effect on our business, operating results and financial condition. In addition, an increase in distribution channels generally makes it more difficult to forecast the mix of products sold and the timing of orders from our customers. New product introductions may result in excess or obsolete inventories, which may also reduce our gross margin. Furthermore, if we are not able to reduce product and warranty costs in future quarters and improve the gross margin of our service line of business, gross margin would continue to be adversely affected.

Cost of product revenue for fiscal 2003 and total cost of revenue in all periods includes the cost of our manufacturing overhead. We outsource the majority of our manufacturing and supply chain management operations, and we conduct quality assurance, manufacturing engineering, document control and repairs at our facility in Santa Clara, California. Accordingly, a significant portion of our cost of revenue consists of payments to our contract manufacturers: Flextronics International, Ltd. located in San Jose, California and Guadalajara, Mexico and Plexus Corp. located in Nampa, Idaho and Penang, Malaysia. As part of our business relationship with MCMS, Inc. (“MCMS”), the predecessor-in-interest to Plexus Corp., in September 2000, we entered into a $9.0 million operating equipment lease for manufacturing equipment with a third-party financing company; we, in turn, subleased the equipment to MCMS. Due to the liquidity problems at MCMS and its voluntary bankruptcy filing for protection under Chapter 11 on September 18, 2001, we recorded a charge of $9.0 million related to the equipment lease in the first quarter of fiscal 2002. On January 8, 2002, MCMS

completed an agreement to sell a majority of its assets to Plexus Corp. for $45.0 million.

We expect to realize lower per-unit product costs from our contract manufacturers as a result of volume efficiencies if and as production volumes increase. However, we do not know if or when such price reductions will occur. The failure to obtain these price reductions could have a material adverse effect upon our gross margin and operating results.

Sales and marketing expenses consist of salaries, commissions and related expenses for personnel engaged in marketing and sales functions, as well as trade shows and promotional expenses. Sales and marketing expenses were $102.5 million in fiscal 2003, $117.9 million in fiscal 2002 and $136.8 million in fiscal 2001, representing a decrease of 12.9% in fiscal 2003 from fiscal 2002 and a decrease of 13.8% in fiscal 2002 from fiscal 2001. The decreases in fiscal 2003 and fiscal 2002 were primarily due to lower aggregate sales commissions and a reduction of 62 people in fiscal 2003 and 67 people in fiscal 2002 in our sales and marketing organization. As a percentage of net revenue, sales and marketing expenses were 28.2% in fiscal 2003, 26.7% in fiscal 2002 and 27.9% in fiscal 2001. We recently announced and implemented a reduction in force and other cost control measures which are intended to reduce our expenses, including sales and marketing expenses, in absolute dollars in the next few quarters. The rate of future spending increases in our sales and marketing expenses, if any, will depend on the pace of recovery in the market for networking products.

Research and development expenses consist principally of salaries and related personnel expenses, consultant fees and prototype expenses related to the design, development, testing and enhancement of our products. Research and development expenses were $58.0 million in fiscal 2003, $61.5 million in fiscal 2002 and $57.9 million in fiscal 2001, representing a decrease of 5.7% in fiscal 2003 from fiscal 2002 and an increase of 6.2% in fiscal 2002 from fiscal 2001. The decrease in fiscal 2003 compared to fiscal 2002 was a result of tightening our focus on our core product lines. The increase in fiscal 2002 over fiscal 2001 was primarily due to higher payroll and related personnel expenses associated with the addition of new personnel, partly through acquisitions, to support our multiple product development efforts as well as non-recurring engineering charges and prototype costs. As a percentage of total net revenue, research and development expenses were 16.0% in fiscal 2003, 13.9% in fiscal 2002 and 11.8% in fiscal 2001. The increase in these percentages in fiscal 2003 and fiscal 2002 and fiscal 2001 was primarily the result of a decrease in our net revenue in fiscal 2003 and fiscal 2002. We expense all research and development expenses as incurred. While we recently implemented a reduction in force and other measures to reduce expenses, including research and development expenses, in the next few quarters, we believe that continued investment in research and development is critical to attaining our strategic objectives. We expect research and development expense to remain in the 12% to 14% range as a percentage of net revenue.

General and administrative expenses consist primarily of salaries and related expenses for executive, finance and administrative personnel, professional fees and other general corporate expenses. General and administrative expenses were $25.7 million in fiscal 2003, $26.9 million in fiscal 2002 and $25.8 million in fiscal 2001, representing a decrease of 4.4% in fiscal 2003 from fiscal 2002 and an increase of 4.3% in fiscal 2002 from fiscal 2001. The decrease in fiscal 2003 from fiscal 2002 was primarily due to decreases in bad debt expense of $4.6 million and rent expense of $1.4 million offset by increases in professional fees of $3.3 million and salaries and benefits of $1.8 million. The increase in fiscal 2002 from fiscal 2001 was due primarily to increased professional fees and directors and officers insurance premiums. As a percentage of net revenue, general and administrative expenses were 7.1% in fiscal 2003, 6.1% in fiscal 2002 and 5.3% in fiscal 2001. The increase in these percentages in fiscal 2003 and fiscal 2002 was primarily the result of decreases in our net revenue in fiscal 2003 and fiscal 2002. In June 2003, we implemented a reduction in force and other expense control measures to reduce expenses, including general and administrative expenses, in the next few quarters. The rate of any future spending increases in our general and administrative expenses, if any, will depend on the pace of recovery in the market for networking products. Increased legal expenses related to intellectual property litigation may also cause general and administrative expenses to increase.

During fiscal 2003, we performed our annual evaluation of goodwill for impairment in accordance with SFAS No. 142 (“SFAS 142”), Goodwill and Other Intangible Assets. This evaluation indicated decreased expected future demand for the products associated with the goodwill and, therefore, we recorded an impairment charge of $1.0 million. During the third quarter of fiscal 2002, we evaluated goodwill and purchased intangible assets associated with recent acquisitions for impairment in accordance with SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of. The assessment was performed as a

result of weakening economic conditions and decreased current and expected future demand for certain categories of products in the markets in which we operate. As a result of the assessment, we recorded a charge to reduce goodwill and purchased intangible assets of $89.8 million.

Amortization of deferred stock compensation was $0.7 million in fiscal 2003, $10.2 million in fiscal 2002 and $4.1 million in fiscal 2001, representing a decrease of $9.5 million in fiscal 2003 from fiscal 2002 and an increase of $6.1 million in fiscal 2002 from fiscal 2001. Amortization of deferred stock compensation is attributable to unvested stock options subject to forfeiture issued to employees that we assumed in conjunction with the acquisitions of Optranet and Webstacks. Deferred stock compensation is amortized as charges to operations, using the graded method, over the vesting periods of the individual stock options, generally four years. Upon termination of an employee, the amount of expense recognized under the graded vesting method that is in excess of the amount actually earned is reversed. For the year ended June 29, 2003, we reversed $5.3 million of excess compensation expense related to terminated employees.

We adopted SFAS 142 as of July 1, 2002. SFAS 142 requires goodwill and certain other intangible assets to be tested for impairment at least annually and written down only when impaired, rather than being amortized as previous accounting standards required. Accordingly, as of July 1, 2002, we stopped amortizing goodwill with a carrying value of $1.0 million. This amount was subsequently written off due to impairment in fiscal 2003.

We recorded in-process research and development charges of $13.4 million related to the purchase of Optranet in January 2001 and $16.8 million related to the purchase of Webstacks in March 2001. The value assigned to purchased in-process research and development was determined through valuation techniques generally used by appraisers in the high-technology industry and was immediately expensed in the period of acquisition because technological feasibility had not been established and no alternative use had been identified.

During fiscal 2003, we recorded restructuring charges of $15.9 million. The restructuring charges included excess facilities charges of $9.6 million, severance charges of $4.4 million and asset impairments of $1.9 million. The excess facilities charge represents an increase to the charge recognized during the third quarter of fiscal 2002. The commercial real estate market has continued to deteriorate since the initial charge was taken in the third quarter of fiscal 2002 necessitating an increase in reserves that take into consideration the unfavorable difference between lease obligation payments and projected sublease receipts. As a result of the excess facilities charges recorded in fiscal 2003 and fiscal 2002, rent expense in fiscal 2004 is expected to decrease by approximately $6.1 million from fiscal 2003 levels. Severance charges of $2.7 million related to a reduction in total staff during the second quarter of fiscal 2003 of approximately 100 people, or 10% of the total workforce, across all departments. Severance charges of $1.7 million related to a reduction in total staff announced at the end of the fiscal year of approximately 70 people, or 8% of the total workforce, across all departments. Compensation expense in fiscal 2004 is expected to decrease by approximately $17.4 million as a result of these reductions. The asset impairment charge relates to the write-off of leasehold improvements and office furniture related to excess facilities. Depreciation expense in fiscal 2004 is expected to decrease by approximately $0.8 million as a result of these facilities-related write-offs.

During fiscal 2002, we implemented a restructuring plan to lower our overall cost structure. Restructuring charges of $73.6 million included a $39.0 million charge related to the exit of two facility leases we entered into in June 2000, excess facilities charges of $25.4 million and a write-off of fixed assets of $9.1 million. The excess facilities charges were the result of our decision to permanently reduce occupancy or vacate certain domestic and international facilities. The asset impairment charge represented the unamortized amount of the assets at the date a decision was made to discontinue use. These assets were not utilized subsequently or held for sale. They were either scrapped or abandoned.

In March 2001, we implemented a restructuring plan in order to lower our overall cost structure. In connection with the restructuring, we reduced our headcount and consolidated facilities. Restructuring charges included in other operating expenses were $3.8 million in the quarter ended March 31, 2001 and $2.1 million in the quarter ended June 30, 2001. The restructuring expense included $1.8 million for severance and benefits for approximately 100 terminated employees, $2.3 million for the write-off and write-down in carrying value of Summit equipment and $1.8 million in facility closure expenses.

During fiscal 2003, we completed a property and equipment physical inventory in conjunction with the implementation of our new ERP system. The property and equipment physical inventory resulted in the identification of $12.7 million of property and equipment whose fair value was determined to be zero because the assets were either no longer in service or were not identifiable. Therefore these assets were written off during the second quarter of fiscal 2003.

Interest income was $11.1 million in fiscal 2003, $11.7 million in fiscal 2002 and $15.5 million in fiscal 2001, representing a decrease of $0.6 million in fiscal 2003 from fiscal 2002 and a decrease of $3.8 million in fiscal 2002 from fiscal 2001. The decrease in fiscal 2003 from fiscal 2002 was due to lower interest rates. The decrease in fiscal 2002 from fiscal 2001 was due to lower interest rates, offset by an increase in our available investment balances due to the net proceeds we received from the issuance of convertible subordinated notes in December 2001.

Interest expense was $7.1 million in fiscal 2003, $4.5 million in fiscal 2002 and $0.4 million in fiscal 2001, representing an increase of $2.6 million in fiscal 2003 from fiscal 2002 and an increase of $4.1 million in fiscal 2002 from fiscal 2001. In December 2001, we completed a private placement of $200.0 million of convertible subordinated notes maturing in 2006. Interest is payable semi-annually at 3.5% per annum. The increase in fiscal 2003 from fiscal 2002 was due to a full year of interest expense on these notes. The increase in fiscal 2002 from fiscal 2001 was due to interest expense on the notes from the date of their issuance through the end of fiscal 2002.

Other expense was $0.2 million in fiscal 2003, $11.1 million in fiscal 2002 and $4.7 million in fiscal 2001. Other expense in fiscal 2003 was primarily comprised of amortization of costs associated with the convertible subordinated notes of $1.2 million and a write-down of investments in privately-held companies of $0.2 million partially offset by translation gains of $1.3 million. The increase in fiscal 2002 from fiscal 2001 was primarily due to write-downs of investments in privately-held companies that are being accounted for under the cost method.

The provision for income taxes of $134.8 million for fiscal 2003 is primarily attributable to a $132.2 million non-cash charge to income tax expense recorded in the fourth quarter of fiscal 2003, representing a full valuation allowance for our net deferred tax assets. We recorded this charge in accordance with Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (“SFAS 109”), which places greater weight on previous cumulative losses than the outlook for future profitability when determining whether deferred tax assets can be realized. Based upon our most recent three-year history of losses and relying on other guidance specified in SFAS 109, we determined that it was appropriate to establish a full valuation allowance against our deferred tax assets. This valuation allowance will be evaluated periodically and can be reversed partially or totally if business results have sufficiently improved to support realization of our deferred tax assets. We recorded a tax benefit of $52.8 million for fiscal 2002. The benefit for fiscal 2002 results in an effective tax benefit rate of 22.3%, which consists primarily of federal and state income tax benefits offset by nondeductible goodwill. We recorded a tax benefit of $22.7 million for fiscal 2001, which consisted primarily of federal and state income tax benefits, offset by foreign taxes, nondeductible in-process research and development and goodwill.

Cash and cash equivalents, short-term investments and marketable securities were $402.2 million and $400.1 million at June 29, 2003 and June 30, 2002, respectively, representing an increase of $2.1 million. This increase was primarily due to cash provided by operating activities of $10.1 million and proceeds from issuance of common stock of $6.3 million, partially offset by capital expenditures of $14.7 million.

We generated $10.1 million in cash from operations in fiscal 2003 despite a net loss of $197.2 million. The net loss included significant non-cash charges including the deferred tax asset valuation allowance of $132.2 million, a restructuring charge of $15.9 million, a property and equipment write-off of $12.7 million and depreciation of $25.9 million. Accounts receivable decreased to $26.8 million at June 29, 2003 from $51.3 million at June 30, 2002. Days sales outstanding in receivables decreased to 28 days at June 29, 2003 from 41 days at June 30, 2002. The decrease in accounts receivable and days sales outstanding were primarily due to shipment

linearity and improved collections performance. Inventory levels decreased to $18.7 million at June 29, 2003 from $24.6 million at June 30, 2002. Inventory management remains an area of focus as we balance the need to maintain strategic inventory levels to ensure competitive lead times and avoid stock-outs with the risk of inventory excess or obsolescence because of recent declining demand, rapidly changing technology and customer requirements. As a result of the rapid change in the market for networking products, we recorded $5.0 million and $39.2 million in charges for excess and obsolete inventory and non-cancelable purchase commitments in fiscal 2002 and 2001, respectively. Deferred revenue increased to $48.3 million at June 29, 2003 from $40.8 million at June 30, 2002. This increase was due primarily to increased service obligations under maintenance contracts.

We have a revolving line of credit for $10.0 million with Silicon Valley Bank. As of June 29, 2003, there were no outstanding borrowings under this facility. The line of credit contains a provision for the issuance of letters of credit not to exceed the unused balance of the line. At June 29, 2003, we had letters of credit totaling $2.1 million. These letters of credit were primarily issued to satisfy requirements of certain of our customers for performance bonds. The line of credit requires us to maintain specified financial covenants related to tangible net worth and liquidity. As of June 29, 2003, we were not in compliance with the tangible net worth covenant and obtained the necessary waiver and expect to be in compliance in future quarters. The line of credit expires on November 30, 2003. It is our intention to renew this line of credit when it expires.

As part of our business relationship with MCMS, Inc., the predecessor-in-interest to Plexus Corp., we entered into a $9.0 million operating equipment lease for manufacturing equipment in September 2000 with a third-party financing company; we, in turn, subleased the equipment to MCMS. The equipment lease with the third-party financing company requires us to make monthly payments through September 2005 and to maintain specified financial covenants related to profitability and our cash to debt ratio with which we were in compliance as of June 29, 2003. The liability related to this lease is included in lease commitments on the balance sheet.

In December 2001, we completed a private placement of $200.0 million of convertible subordinated notes. The notes mature on December 1, 2006. Interest is payable semi-annually at 3.5% per annum. The notes are convertible at the option of the holders into our common stock at an initial conversion price of $20.96 per share, subject to adjustment. The notes are redeemable in cash at our option at an initial redemption price of 101.4% of the principal amount on or after December 2004 if not converted to common stock prior to the redemption date. Each holder of the notes has the right to cause us to repurchase all of such holder’s convertible notes at 100% of the principal amount plus accrued interest upon a change of control of ownership of Extreme Networks, as defined in the offering circular. Instead of paying the repurchase price in cash, we may, if we satisfy certain conditions, elect to pay the repurchase price in common stock valued at 95% of the average of the closing prices of our common stock for the five trading days immediately preceding and including the third trading day prior to the repurchase date.

The following summarizes our contractual obligations (including interest payments) at June 29, 2003, and the effect such obligations are expected to have on our liquidity and cash flow in future periods (in thousands):

We did not have any material commitments for capital expenditures or non-cancelable purchase commitments as of June 29, 2003.

We require substantial capital to fund our business, particularly to finance inventories and accounts receivable and for capital expenditures. As a result, we could be required to raise substantial additional capital at any time. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of such securities could result in dilution to existing stockholders. If additional funds are raised through the issuance of debt securities, these securities may have rights, preferences and privileges senior to holders of common stock and the terms of such debt could impose restrictions on our operations. If we are unable to obtain such additional capital, we may be required to reduce the scope of our planned product development and marketing efforts, which would materially adversely affect our business, financial condition and operating results.

We believe that our current cash and cash equivalents, short-term investments, marketable securities and cash available from credit facilities and future operations will enable us to meet our working capital requirements for at least the next 12 months.

In November 2002, the Emerging Issues Task Force (“EITF”) reached a consensus on Issue No. 00-21, Revenue Arrangements with Multiple Deliverables (“EITF 00-21”). EITF 00-21 provides guidance on how to account for arrangements that involve the delivery or performance of multiple products, services and/or rights to use assets. The provisions of EITF 00-21 will apply to revenue arrangements entered into in fiscal periods beginning after June 15, 2003. We are currently evaluating the effect that the adoption of EITF 00-21 will have on our results of operations and financial condition.

In January 2003, the FASB issued FASB Interpretation No. 46, Consolidation of Variable Interest Entities (“FIN 46”). FIN 46 requires that if an entity has a controlling financial interest in a variable interest entity, the assets, liabilities, and results of activities of the variable interest entity should be included in the consolidated financial statements of the entity. For arrangements entered into after January 31, 2003, FIN 46 is effective immediately. For arrangements entered into prior to January 31, 2003, FIN 46 is effective for the first interim or annual period beginning after June 15, 2003. We have no contractual relationships or other business relationships with any variable interest entities that were entered into after January 31, 2003 and, therefore, the initial adoption of FIN 46 did not have an effect on our results of operations or financial condition. We are currently evaluating whether we have any contractual relationships or other business arrangements prior to January 31, 2003 that will be subject to FIN 46 as of June 30, 2003.

In April 2003, the FASB issued SFAS No. 149, Amendment of Statement 133 on Derivative Instruments and Hedging Activities (“SFAS 149”). SFAS 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contacts, and for hedging activities under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities (“SFAS 133”). SFAS 149 also amends SFAS 133 for decisions made (1) as part of the Derivatives Implementation Group process that effectively required amendments to SFAS 133, (2) in connection with other FASB projects dealing with financial instruments, and (3) in connection with implementation issues raised in relation to the application of the definition of a derivative. SFAS 149 is effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. Provisions of SFAS 149 will be applied prospectively. We do not expect the adoption of SFAS 149 to have a material impact on our operating results or financial condition.

Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity

In May 2003, the FASB issued SFAS No. 150, Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity, (“SFAS 150”). SFAS 150 establishes standards for classifying and measuring as liabilities certain financial instruments that embody obligations of the issuer and have characteristics of both liabilities and equity. SFAS 150 must be applied immediately to instruments entered into or modified after May 31, 2003. The adoption of SFAS 150 did not have a material effect on our results of operations or financial position.

On July 31, 2003, EITF reached a consensus on its tentative conclusions on Issue No. 03-5, Applicability of AICPA Statement of Position 97-2, “Software Revenue Recognition,” to Non-Software Deliverables in an Arrangement Containing More-Than Incidental Software (“EITF 03-5”). EITF 03-5 discusses that software deliverables are within the scope of SOP 97-2 as are non-software deliverable(s) for which the related software is essential to the functionality of the non-software deliverable(s). Companies are required to adopt this consensus for fiscal periods beginning after August 2003. We believe the adoption of EITF 03-5 will not have a material impact on our financial position, results of operations or liquidity.

We Are Not Profitable and We Cannot Assure You That We Will Be Profitable in the Future

Fiscal 2000 was the only year in which we have achieved profitability. We reported losses for fiscal 2003, fiscal 2002 and fiscal 2001. We anticipate continuing to incur significant sales and marketing, product development and general and administrative expenses and, as a result, we will continue to need to rationalize expense levels and increase revenue levels to achieve profitability in future fiscal quarters.

A Number of Factors Could Cause Our Quarterly Financial Results to Be Worse Than Expected, Resulting in a Decline in Our Stock Price

Our failure to control our operating expenses at a level that is consistent with anticipated revenue may cause our financial results to be worse than expected. A high percentage of our expenses are fixed in the short term, so any delay in generating or recognizing revenue could cause our quarterly operating results to fall below the expectations of public market analysts or investors, which could cause the price of our stock to fall.

We may experience a delay in generating or recognizing revenue for a number of reasons. Orders at the beginning of each quarter do not equal expected revenue for that quarter and are generally cancelable at any time. Accordingly, we are dependent upon obtaining orders during a quarter and shipping those orders in the same quarter to achieve our revenue objectives. In addition, the timing of product releases and purchase orders, in addition to product availability, often results in a majority of our product shipments being scheduled near the end of a quarter. Failure to ship these products by the end of a quarter may adversely affect our operating results. Our customer agreements generally allow customers to delay scheduled delivery dates or to cancel orders within specified timeframes without significant charges to the customers. Furthermore, some of our customers require that we provide installation or inspection services that may delay the recognition of revenue for both products and services, and some of our customer agreements include acceptance provisions that prevent our ability to recognize revenue upon shipment.

Our quarterly revenue and operating results have varied significantly in the past and may vary significantly in the future due to a number of factors, including, but not limited to, the following:

Due to the foregoing factors, we believe that period-to-period comparisons of our operating results should not be relied upon as an indicator of our future performance.

Intense Competition in the Market for Networking Equipment Could Prevent Us from Increasing Revenue and Returning to Profitability

The market for networking equipment is intensely competitive. Our principal competitors include Cisco Systems, Enterasys Networks, Foundry Networks, Inc., Nortel Networks and Riverstone Networks. In addition, a number of private companies have announced plans for new products, or have introduced products, that may compete with our own products. Some of our current and potential

competitors have superior market leverage, longer operating histories and substantially greater financial, technical, sales and marketing resources, in addition to wider name recognition and larger installed customer bases. These competitors may have developed, or may in the future develop, new competing products based on technologies that compete with our own products or render our products obsolete. Furthermore, a number of these competitors may merge or form strategic partnerships that enable them to offer or bring to market competitive products. Consolidation within our industry could lead to increased competition and could harm our operating results.

The pricing policies of our competitors impact the overall demand for our products and services. Some of our competitors are capable of operating at significant losses for extended periods of time, increasing pricing pressure on our products and services. If we do not maintain competitive pricing, the demand for our products and services, as well as our market share, may decline. From time to time, in responding to competitive pressures, we lower the prices of our products and services. When this happens, if we are unable to reduce our component costs or improve operating efficiencies, our revenues and margins are adversely affected.

To remain competitive, we believe that we must, among other things, invest significant resources in developing new products, improve our current products and maintain customer satisfaction. Such investment will increase our expenses and affect our profitability. In addition, if we fail to make this investment, we may not be able to compete successfully with our competitors, which could have a material adverse effect on our revenue and future profitability.

When Our Products Contain Undetected Software or Hardware Errors, We Incur Significant Unexpected Expenses and Could Lose Sales

Network products frequently contain undetected software or hardware errors when new products or new versions or updates of existing products are first released to the marketplace. In the past, we have experienced such errors in connection with new products and product upgrades. We have experienced component problems that caused us to incur higher than expected warranty and service costs and expenses and to take an accrual for anticipated expenses. Such expenses adversely affected our results for fiscal 2003 and fiscal 2002. We have undertaken extensive efforts to address these issues, however until these programs are completed, these expenses are expected to exceed normal levels. In the future, we expect that, from time to time, such errors or component failures will be found in new or existing products after the commencement of commercial shipments including the components we incorporate in our products. These problems may have a material adverse effect on our business by causing us to incur significant warranty and repair costs, diverting the attention of our engineering personnel from new product development efforts, delaying the recognition of revenue and causing significant customer relations problems. Further, if products are not accepted by customers due to such defects, and such returns exceed the amount we accrued for defect returns based on our historical experience, our operating results would be adversely affected.

Our products must successfully interoperate with products from other vendors. As a result, when problems occur in a network, it may be difficult to identify the sources of these problems. The occurrence of hardware and software errors, whether or not caused by our products, could result in the delay or loss of market acceptance of our products and any necessary revisions may cause us to incur significant expenses. The occurrence of any such problems would likely have a material adverse effect on our business, operating results and financial condition.

We Depend Upon International Sales for a Significant Portion of Our Revenue and Our Ability to Grow Our International Sales Depends on Successfully Expanding Our International Operations

International sales constitute a significant portion of our net revenue. Our ability to grow will depend in part on the continued expansion of international sales. Sales to customers outside of the United States accounted for approximately 60%, 67% and 57% of our net revenue, respectively, for fiscal 2003, fiscal 2002 and fiscal 2001. Our international sales primarily depend on the success of our resellers and distributors. The failure of our resellers and distributors to sell our products internationally would limit our ability to sustain and grow our revenue. There are a number of risks arising from our international business, including:

In addition, conducting our business on a global basis subjects us to a number of frequently changing and complex trade protection measures and import or export regulatory requirements. Our failure to comply with these measures and regulatory requirements may result in the imposition of financial penalties and restrictions on our ability to conduct business in and with certain countries, which may harm our business and damage our reputation. Pursuant to regulations of the U.S. Department of Commerce providing for voluntary disclosure, we have disclosed information regarding a possible violation of certain export regulations. Following such disclosures the Department of Commerce will determine whether to conduct an investigation. If an investigation is commenced, we believe that these matters will be resolved without a material adverse effect on our business, and we have implemented procedures to reduce the risk of violations in the future.

Our international sales currently are U.S. dollar-denominated. As a result, increases in the value of the U.S. dollar relative to foreign currencies could make our products less competitive in international markets. In the future, we may elect to invoice some of our international customers in local currency which will expose us to fluctuations in exchange rates between the U.S. dollar and the particular local currency.

If we do so, we may decide to engage in hedging transactions to minimize the risk of such fluctuations. We have entered into foreign exchange forward contracts to offset the impact of payment of operating expenses in local currencies to some of our operating foreign subsidiaries. However, if we are not successful in managing these hedging transactions, we could incur losses from hedging activities.

We Expect the Average Selling Prices of Our Products to Decrease, Which May Reduce Gross Margin or Revenue

The network equipment industry has traditionally experienced a rapid erosion of average selling prices due to a number of factors, including competitive pricing pressures, promotional pricing and technological progress. In addition, companies have lowered their prices in order to liquidate excess inventory that has accumulated as a result of the current economic slowdown. We anticipate that the average selling prices of our products will decrease in the future in response to competitive pricing pressures, excess inventories, increased sales discounts and new product introductions by us or our competitors, including, for example, competitive products manufactured with low-cost merchant silicon. We may experience substantial decreases in future operating results due to the erosion of our average selling prices. Competitive pressures are expected to increase as a result of the industry slowdown that began in the first half of 2001, coupled with the recent downturn in the broader economy. To maintain our gross margin, we must develop and introduce on a timely basis new products and product enhancements and continually reduce our product costs. Our failure to do so would likely cause our revenue and gross margins to decline, which could have a material adverse effect on our operating results and cause the price of our common stock to decline.

Some of Our Customers May Not Have the Resources to Pay for Our Products as a Result of the Current Economic Environment

With the current economic slowdown, some of our customers are forecasting that their revenue for the foreseeable future will generally be lower than originally anticipated. Some of these customers are experiencing, or are likely to experience, serious cash flow problems and, as a result, may find it increasingly difficult to obtain financing, if financing is available at all. If some of these customers are not successful in generating sufficient revenue or securing alternate financing arrangements, they may not be able to pay, or may delay payment of, the amounts that they owe us. In particular, sales to the service provider market are especially volatile and continued declines or delays in sale orders from this market may harm our financial condition. Furthermore, they may not order as many products from us as originally forecast, or cancel orders with us entirely. The inability of some of our potential customers to pay us for our products may adversely affect our cash flow, the timing of our revenue recognition and the amount of revenue, which may cause our stock price to decline.

The Market in Which We Compete is Subject to Rapid Technological Progress and to Compete We Must Continually Introduce New Products that Achieve Broad Market Acceptance

The network equipment market is characterized by rapid technological progress, frequent new product introductions, changes in customer requirements and evolving industry standards. If we do not regularly introduce new products in this dynamic environment, our product lines will become obsolete. Developments in routers and routing software could also significantly reduce demand for our products. Alternative technologies could achieve widespread market acceptance and displace the Ethernet technology on which we have based our product architecture. We cannot assure you that our technological approach will achieve broad market acceptance or that other technologies or devices will not supplant our own products and technology.

When we announce new products or product enhancements that have the potential to replace or shorten the life cycle of our existing products, customers may defer or cancel orders for our existing products. These actions could have a material adverse effect on our operating results by unexpectedly decreasing sales, increasing inventory levels of older products and exposing us to greater risk of product obsolescence. The market for switching products is evolving and we believe our ability to compete successfully in this market is dependent upon the continued compatibility and interoperability of our products with products and architectures offered by other vendors. In particular, the networking industry has been characterized by the successive introduction of new technologies or standards that have dramatically reduced the price and increased the performance of switching equipment. To remain competitive, we need to introduce products in a timely manner that incorporate, or are compatible with, these emerging technologies. We are particularly dependent upon the successful introduction of new products in calendar year 2003. We cannot assure you that any new products we introduce will be commercially successful. We have experienced delays in releasing new products and product enhancements in the past that resulted in lower quarterly revenue than anticipated. We may experience similar delays in product development and releases in the future, and any delay in product introduction could adversely affect our ability to compete, causing our operating results to be below our expectations or the expectations of public market analysts or investors.

Our Limited Ability to Protect Our Intellectual Property and Defend Against Claims May Adversely Affect Our Ability to Compete

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. However, we cannot assure you that the actions we have taken will adequately protect our intellectual property rights or that other parties will not independently develop similar or competing products that do not infringe on our patents. We enter into confidentiality or license agreements with our employees, consultants and corporate partners, and control access to and distribution of our software, documentation and other proprietary information. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise misappropriate or use our products or technology.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. We are actively involved in disputes and licensing discussions with others regarding their claimed proprietary rights and cannot assure you that we will always successfully defend ourselves against such claims. If we are found to infringe the proprietary rights of others, or if we otherwise settle such claims, we could be compelled to pay damages or royalties and either obtain a license to those intellectual property rights or alter our products so that they no longer infringe upon such proprietary rights. Any license could be very expensive to obtain or may not be available at all. Similarly, changing our products or processes to avoid infringing the rights of others may be costly or impractical. Litigation resulting from claims that we are infringing the proprietary rights of others could result in substantial costs and a diversion of resources, and could have a material adverse effect on our business, financial condition and results of operations.

We Are Engaged in Litigation Regarding Intellectual Property Rights, and an Adverse Outcome Could Harm Our Business and Require Us to Incur Significant Costs

We have received notice from several major companies alleging that we are infringing their patents. One of these companies, Lucent Technologies, Inc., filed a claim against us alleging patent infringement and we are in litigation as of the date of this filing. Following examination of this claim, we believe it is without merit and we have responded accordingly. Without regard to the merits of this or any other claim, if judgments by a court of law on this or any other claim received in the future were to be upheld, or if we otherwise agree to the settlement of such claims, the consequences to us may be severe and could require us to, among other actions:

If we are compelled to take any of the foregoing actions, our business could be severely harmed.

Adjustments to the Size of Our Operations May Require Us to Incur Unanticipated Costs

Prior to the quarter ended April 1, 2001, we experienced rapid growth and expansion that placed, and may in the future place, a significant strain on our resources. Subsequent to that period, we have from time to time incurred unanticipated costs to downsize our operations to a level consistent with downward forecasts in sales. Even if we manage the current period of instability effectively, as well as possible expansion in the future, we may make mistakes in restructuring or operating our business such as inaccurate sales

forecasting or incorrect material planning. Any of these mistakes may lead to unanticipated fluctuations in our operating results. We cannot assure you that we will be able to size our operations in accordance with growth or decline of our business in the future.

Delays in the Implementation of New Management Information Systems May Cause a Significant Burden on Our Operations

We have implemented additional management information systems and are developing further operating, administrative, financial and accounting systems and controls to improve and maintain close coordination among our executive, engineering, accounting, finance, marketing, sales and operations organizations. In addition, we recently completed the transition to a new enterprise resource planning system. We may be unable to operate our control systems in an efficient manner, and our current or planned personnel systems, procedures, and controls may not be adequate to support our future operations. The difficulties associated with designing and implementing these new systems, procedures, and controls may place a significant burden on our management and our internal resources. In addition, as we grow internationally, we will need to expand our worldwide operations and enhance our communications infrastructure. Any delay in the implementation of such new or enhanced systems, procedures or controls, or any disruption in the transition to such new or enhanced systems, procedures or controls, could adversely affect our ability to accurately forecast sales demand, manage our supply chain, and record and report financial and management information on a timely and accurate basis.

We Must Continue to Develop and Increase the Productivity of Our Indirect Distribution Channels to Increase Net Revenue and Improve Our Operating Results

Our distribution strategy focuses primarily on developing and increasing the productivity of our indirect distribution channels through resellers and distributors. If we fail to develop and cultivate relationships with significant resellers, or if these resellers are not successful in their sales efforts, sales of our products may decrease and our operating results could suffer. Many of our resellers also sell products from other vendors that compete with our products. We cannot assure you that we will be able to enter into additional reseller and/or distribution agreements or that we will be able to successfully manage our product sales channels. Our failure to do any of these could limit our ability to grow or sustain revenue. In addition, our operating results will likely fluctuate significantly depending on the timing and amount of orders from our resellers. We cannot assure you that our resellers and/or distributors will continue to market or sell our products effectively or continue to devote the resources necessary to provide us with effective sales, marketing and technical support.

Most of Our Revenue is Derived From Sales of Three Product Families, So We are Dependent on Widespread Market Acceptance of These Products

During fiscal 2003, we derived substantially all of our revenue from sales of our Summit, BlackDiamond and Alpine products and related services. We expect that revenue from these product families will account for a substantial portion of our revenue for the foreseeable future. Accordingly, widespread market acceptance of our product families is vital to our future success. Factors that may affect the sales of our products, some of which are beyond our control, include:

We may not be able to achieve widespread market acceptance of our product families, which could reduce our revenue.

Future Performance will Depend on the Introduction and Acceptance of New Products

Our future performance will also depend on the successful development, introduction, and market acceptance of new and enhanced products that address customer requirements in a timely and cost-effective manner. In particular, we are dependent upon the successful introduction of new products in calendar year 2003. In the past, we have experienced delays in product development and such delays may occur in the future. We have recently announced a third-generation chipset for use in future products. The introduction of new and enhanced products may cause our customers to defer or cancel orders for existing products. Therefore, to the extent customers defer or cancel orders in the expectation of new product releases, any delay in the development or introduction of new products could cause our operating results to suffer. The inability to achieve and maintain widespread levels of market acceptance for our current and future products may significantly impair our revenue growth.

If a Key Reseller, Distributor, or Other Significant Customer Cancels or Delays a Large Purchase, Our Net Revenue May Decline and the Price of Our Stock May Fall

To date, a limited number of resellers, distributors and other customers have accounted for a significant portion of our revenue. If any of our large customers stop or delay purchases, our revenue and profitability would be adversely affected. For example, one distributor of Extreme Networks’ products accounted for 11%, 15% and 16% of Extreme Networks’ net revenue for fiscal 2003, fiscal 2002 and fiscal 2001, respectively. Our expense levels are based on our expectations as to future revenue and to a large extent are fixed in the short term, so a substantial reduction or delay in sales of our products to a significant reseller, distributor or other customer could harm our business, operating results and financial condition. Although our largest customers may differ from period-to-period, we anticipate that our operating results for any given period will continue to depend to a significant extent on large orders from a relatively small number of customers, particularly in view of the relatively high per unit sales price of our products and long sales cycles.

While our financial performance depends on large orders from a limited number of key resellers, distributors and other significant customers, we do not have binding purchase commitments from any of them. For example:

Under specified conditions, some third-party distributors are allowed to return products to us. We do not recognize revenue on sales to distributors until the distributors sell the product to their customers.

The Sales Cycle for Our Products is Long and We May Incur Substantial Non-Recoverable Expenses or Devote Significant Resources to Sales that Do Not Occur When Anticipated

The use of indirect sales channels may contribute to the length and variability of our sales cycle. Our products have a relatively high per unit sales price, and the purchase of our products often constitutes a significant strategic decision by a customer regarding its communications infrastructure. The decision by customers to purchase our products is often based on the results of a variety of internal procedures associated with the evaluation, testing, implementation and acceptance of new technologies. Accordingly, the product evaluation process frequently results in a lengthy sales cycle, typically ranging from three months to longer than a year, and as a result, our ability to sell products is subject to a number of significant risks, including:

We Purchase Several Key Components for Products From Single or Limited Sources and Could Lose Sales if These Suppliers Fail to Meet Our Needs

We currently purchase several key components used in the manufacture of our products from single or limited sources and are dependent upon supply from these sources to meet our needs. Certain components such as tantalum capacitors, static random access memory, or SRAM, and printed circuit boards have been, and may be in the future, in short supply. We have in the past, and are likely in the future, to encounter shortages and delays in obtaining these or other components, and this could have a material adverse effect on our ability to meet customer orders. Our principal sole-source components include:

We use our forecast of expected demand to determine our material requirements. Lead times for materials and components we order vary significantly, and depend on factors such as the specific supplier, contract terms and demand for a component at a given time. If forecasts exceed orders, we may have excess and/or obsolete inventory on hand or under non-cancelable purchase commitments that could have a material adverse effect on our operating results and financial condition. If orders exceed forecasts, we may have inadequate inventory of certain materials and components, which could have a material adverse effect on our operating results and financial condition. We do not have agreements fixing long-term prices or minimum volume requirements from these suppliers. From time to time we have experienced shortages and allocations of certain components, resulting in delays in filling orders. Qualifying new suppliers to compensate for such shortages may be time-consuming and costly, and may increase the likelihood of errors in design or production. In addition, during the development of our products, we have experienced delays in the prototyping of our chipsets, which in turn has led to delays in product introductions. We cannot assure you that similar delays will not occur in the future. Furthermore, we cannot assure you that the performance of the components as incorporated in our products will meet the quality requirements of our customers.

Our Dependence on Contract Manufacturers for Substantially All of Our Manufacturing Requirements Could Harm Our Operating Results

If the demand for our products grows, we will need to increase our material purchases, contract manufacturing capacity, and internal test and quality functions. Any disruptions in product flow could limit our revenue, adversely affect our competitive position and reputation, and result in additional costs or cancellation of orders under agreements with our customers.

We rely on independent contractors to manufacture our products. We do not have long-term contracts with any of these manufacturers. We currently utilize two companies for the manufacture of our products – Flextronics International, Ltd., located in San Jose, California and Guadalajara, Mexico and Plexus Corp., located in Nampa, Idaho and Penang, Malaysia. We have experienced delays in product shipments from contract manufacturers in the past, which in turn delayed product shipments to our customers. Similar or other problems may arise in the future, such as products of inferior quality, insufficient quantity of products, or the interruption or discontinuance of operations of a manufacturer, any of which could have a material adverse effect on our business and operating results.

We do not know whether we will effectively manage our contract manufacturers or that these manufacturers will meet our future requirements for timely delivery of products of sufficient quality and quantity. We intend to transition the manufacture of some of our products from one contract manufacturer to another. We also intend to regularly introduce new products and product enhancements, which will require that we rapidly achieve volume production by coordinating our efforts with those of our suppliers and contract manufacturers. The inability of our contract manufacturers to provide us with adequate supplies of high-quality products, or a reduction in the number of our contract manufacturers may cause a delay in our ability to fulfill orders and may have a material adverse effect on our business, operating results and financial condition.

As part of our cost-reduction efforts, we will need to realize lower per unit product costs from our contract manufacturers by means of volume efficiencies and the utilization of manufacturing sites in lower-cost geographies. However, we cannot be certain when or if such price reductions will occur. The failure to obtain such price reductions would adversely affect our gross margins and operating results.

Future Changes in Financial Accounting Standards May Cause Adverse Unexpected Revenue Fluctuations and Affect Our Reported Results of Operations

A change in accounting policies can have a significant effect on our reported results and may even affect our reporting of transactions completed before the change is effective. New pronouncements and varying interpretations of pronouncements have occurred with frequency and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our

In particular, if we are required to record stock option grants as compensation expense on our income statement, our profitability may be reduced significantly. The current methodology for expensing such stock options is based on, among other things, the historical volatility of the underlying stock. Our stock price has been historically volatile. Therefore, the adoption of an accounting standard requiring companies to expense stock options would negatively impact our profitability and may adversely impact our stock price. In addition, the adoption of such a standard could limit our ability to continue to use stock options as an incentive and retention tool, which could, in turn, hurt our ability to recruit employees and retain existing employees.

Compliance with Changing Regulation of Corporate Governance and Public Disclosure May Result in Additional Expenses

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations and Nasdaq Stock Market rules, are creating uncertainty for companies such as ours. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, we intend to invest all reasonably necessary resources to comply with evolving standards, and this investment may result in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

We Have Been Named as a Defendant in a Shareholder Class Action Lawsuit Arising Out of Our Public Offerings of Securities in 1999

In addition, we may become subject to other types of litigation in the future. Litigation is often expensive and diverts management’s attention and resources, which could materially and adversely affect our business.

Our Headquarters Are Located in Northern California and Certain of Our Contract Manufacturers Are Located Where Disasters May Occur That Could Disrupt Our Operations and Harm Our Business

Our corporate headquarters are located in Silicon Valley in Northern California. Historically, this region has been vulnerable to natural disasters and other risks, such as earthquakes, fires and floods, which at times have disrupted the local economy and posed physical

risks to our property. We have contract manufacturers located in Northern California and in Mexico where similar natural disasters and other risks may disrupt the local economy and pose physical risks to our property and the property of our manufacturers.

In addition, terrorist acts or acts of war targeted at the United States, and specifically Silicon Valley, could cause damage or disruption to us, our employees, facilities, partners, suppliers, distributors and resellers, and customers, which could have a material adverse effect on our operations and financial results.

We currently do not have redundant, multiple site capacity in the event of a natural disaster or catastrophic event. In the event of such an occurrence, our business would suffer.

If We Lose Key Personnel or are Unable to Hire Additional Qualified Personnel as Necessary, We May Not Be Able to Successfully Manage Our Business or Achieve Our Goals

Our success depends to a significant degree upon the continued contributions of our key management, engineering, sales, marketing and service and operations personnel, many of whom would be difficult to replace. We do not have employment contracts with these individuals nor do we carry life insurance on any of our key personnel.

We believe our future success will also depend in large part upon our ability to attract and retain highly skilled managerial, engineering, sales, marketing and service, finance and operations personnel. The market for these personnel is competitive, especially in the San Francisco Bay Area, and we have had difficulty in hiring employees, particularly engineers, in the timeframe we desire. In addition, retention has become more difficult for us and other public technology companies as a result of the stock market decline, which caused the price of many of our employees’ stock options to be above the current market price of our stock. There can be no assurance that we will be successful in attracting and retaining such personnel. The loss of the services of any of our key personnel, the inability to attract or retain qualified personnel in the future or delays in hiring desired personnel, particularly engineers and sales personnel, could make it difficult for us to manage our business and meet key objectives, such as new product introductions. In addition, companies in the networking industry whose employees accept positions with competitors frequently claim that competitors have engaged in unfair hiring practices. We have from time to time been involved in claims like this with other companies and, although to date they have not resulted in material litigation, we do not know whether we will be involved in additional claims in the future as we seek to hire and retain qualified personnel or that such claims will not result in material litigation. We could incur substantial costs in litigating any such claims, regardless of the merits.

Our Products Must Comply With Evolving Industry Standards and Complex Government Regulations or Else Our Products May Not Be Widely Accepted, Which May Prevent Us From Growing Our Net Revenue or Achieving Profitability

The market for network equipment products is characterized by the need to support industry standards as different standards emerge, evolve and achieve acceptance. We will not be competitive unless we continually introduce new products and product enhancements that meet these emerging standards. In the past, we have introduced new products that were not compatible with certain technological standards, and in the future we may not be able to effectively address the compatibility and interoperability issues that arise as a result of technological changes and evolving industry standards. Our products must comply with various United States federal government regulations and standards defined by agencies such as the Federal Communications Commission, in addition to standards established by governmental authorities in various foreign countries and recommendations of the International Telecommunication Union. If we do not comply with existing or evolving industry standards or if we fail to obtain timely domestic or foreign regulatory approvals or certificates we will not be able to sell our products where these standards or regulations apply, which may prevent us from sustaining our net revenue or achieving profitability.

Failure to Successfully Expand Our Sales and Support Teams or Educate Them In Regard to Technologies and Our Product Families May Harm Our Operating Results

The sale of our products and services requires a concerted effort that is frequently targeted at several levels within a prospective customer’s organization. We may not be able to increase net revenue unless we expand our sales and support teams in order to address all of the customer requirements necessary to sell our products.

We cannot assure you that we will be able to successfully integrate employees into our company or to educate current and future employees in regard to rapidly evolving technologies and our product families. A failure to do so may hurt our revenue growth and operating results.

We May Engage in Future Acquisitions that Dilute the Ownership Interests of Our Stockholders, Cause Us to Incur Debt and

As part of our business strategy, we review acquisition and strategic investment prospects that we believe would complement our current product offerings, augment our market coverage or enhance our technical capabilities, or otherwise offer growth opportunities. From time to time we review investments in new businesses and we expect to make investments in, and to acquire, businesses, products, or technologies in the future. In the event of any future acquisitions, we could:

These actions by us could have a material adverse effect on our operating results or the price of our common stock. Moreover, even if we do obtain benefits in the form of increased sales and earnings, there may be a lag between the time when the expenses associated with an acquisition are incurred and the time when we recognize such benefits. This is particularly relevant in cases where it is necessary to integrate new types of technology into our existing portfolio and new types of products may be targeted for potential customers with which we do not have pre-existing relationships. Acquisitions and investment activities also entail numerous risks, including:

We cannot assure you that we will be able to successfully integrate any businesses, products, technologies, or personnel that we might acquire in the future, and our failure to do so could have a material adverse effect on our business, operating results and financial condition.

We May Need Additional Capital to Fund Our Future Operations and, If It Is Not Available When Needed, We May Need to Reduce Our Planned Development and Marketing Efforts, Which May Reduce Our Net Revenue and Prevent Us From Achieving Profitability

We believe that our existing working capital and cash available from credit facilities and future operations, will enable us to meet our working capital requirements for at least the next 12 months. However, if cash from future operations is insufficient, or if cash is used for acquisitions or other currently unanticipated uses, we may need additional capital. The development and marketing of new products and the expansion of reseller and distribution channels and associated support personnel requires a significant commitment of resources. In addition, if the markets for our products develop more slowly than anticipated, or if we fail to establish significant market share and achieve sufficient net revenue, we may continue to consume significant amounts of capital. As a result, we could be required to raise additional capital. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of such securities could result in dilution of the shares held by existing stockholders. If additional funds are raised through the issuance of debt securities, such securities may provide the holders certain rights, preferences, and privileges senior to those of common stockholders, and the terms of such debt could impose restrictions on our operations. We cannot assure you that additional capital, if required, will be available on acceptable terms, or at all. If we are unable to obtain sufficient amounts of additional capital, we may be required to reduce the scope of our planned product development and marketing efforts, which could harm our business, financial condition and operating results.

We Significantly Increased Our Leverage as a Result of the Sale of Convertible Subordinated Notes

In connection with the sale of convertible subordinated notes in December 2001, we incurred $200 million of indebtedness. We will require substantial amounts of cash to fund scheduled payments of interest on the convertible notes, payment of the principal amount of the convertible notes, future capital expenditures, payments on our leases and any increased working capital requirements. If we are unable to meet our cash requirements out of cash flow from operations, there can be no assurance that we will be able to obtain alternative financing. The degree to which we are financially leveraged could materially and adversely affect

our ability to obtain financing for working capital, acquisitions or other purposes and could make us more vulnerable to industry downturns and competitive pressures. In the absence of such financing, our ability to respond to changing business and economic conditions, to make future acquisitions, to absorb adverse operating results or to fund capital expenditures or increased working capital requirements would be significantly reduced. Our ability to meet our debt service obligations will be dependent upon our future performance, which will be subject to financial, business and other factors affecting our operations, some of which are beyond our control. If we do not generate sufficient cash flow from operations to repay the notes at maturity, we could attempt to refinance the notes; however, no assurance can be given that such a refinancing would be available on terms acceptable to us, if at all. Any failure by us to satisfy our obligations with respect to the notes at maturity (with respect to payments of principal) or prior thereto (with respect to payments of interest or required repurchases) would constitute a default under the indenture and could cause a default under agreements governing our other indebtedness.

We Have Entered into Long-Term Lease Agreements for Several Facilities that are Currently Vacant and May be Difficult to Sublease due to Current Real Estate Market Conditions

We have certain long-term real estate lease commitments carrying future obligations for non-cancelable lease payments net of estimated sublease income. Reductions in our workforce and the restructuring of operations during fiscal 2003 and 2002 resulted in the need to consolidate certain of these leased facilities, located primarily in Northern California. We recorded excess facilities charges of $9.6 million in fiscal 2003 and $25.4 million during fiscal 2002. For more information, see Note 13 of Notes to Condensed Consolidated Financial Statements. We intend to sublease certain of these facilities and may obtain sublease income to offset the carrying costs of these facilities. However, based on the continuing deterioration of commercial real estate market conditions in connection with a downturn in the economy, we will not be able to sublease these facilities at the times or on the terms we anticipated when we took the excess facilities charge and therefore if the market does not improve, we may incur additional charges in the future. In addition, we may incur additional charges for excess facilities as a result of additional reductions in our workforce or future restructuring of operations. We will continue to be responsible for all carrying costs of these facilities until such time as we can sublease these facilities or terminate the applicable leases based on the contractual terms of the lease agreements, and these costs may have an adverse effect on our business, operating results and financial condition.

Our Stock Price Has Been Volatile In the Past and Our Stock Price and the Price of the Notes May Significantly Fluctuate in the Future

In the past, our common stock price has fluctuated significantly. This could continue as we or our competitors announce new products, our customers’ results fluctuate, conditions in the networking or semiconductor industry change, or when investors change their sentiment toward stocks in the networking technology sector.

In addition, fluctuations in our stock price and our price-to-earnings multiple may make our stock attractive to momentum, hedge or day-trading investors who often shift funds into and out of stock rapidly, exacerbating price fluctuations in either direction, particularly when viewed on a quarterly basis.

We may decide to raise additional funds through public or private debt or equity financing to fund our operations. If we raise funds by issuing equity securities, the percentage ownership of current stockholders will be reduced and the new equity securities may have rights prior to those of our common stock, including the common stock issuable upon conversion of the notes. We may not obtain sufficient financing on terms that are favorable to you or us. We may delay, limit or eliminate some or all of our proposed operations if adequate funds are not available.

Provisions in Our Charter Documents and Delaware Law and Our Adoption of a Stockholder Rights Plan May Delay or Prevent Acquisition Of Us, Which Could Decrease the Value of Our Common Stock and, Therefore, the Notes

Our certificate of incorporation and bylaws and Delaware law contain provisions that could make it more difficult for a third party to acquire us without the consent of our board of directors. Delaware law also imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. In addition, our board of directors has the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer. Although we believe these provisions of our certificate of incorporation and bylaws and Delaware law and our stockholder rights plan, which is described below, will provide for an opportunity to receive a higher bid by requiring potential acquirers to negotiate with our board of directors, these provisions apply even if the offer may be considered beneficial by some of our stockholders.

Our board of directors adopted a stockholder rights plan, pursuant to which we declared and paid a dividend of one right for each share of common stock held by stockholders of record as of May 14, 2001. Under the plan, each right will entitle stockholders to purchase a fractional share of our preferred stock for $150.00. Each such fractional share of the new preferred stock has terms designed to make it substantially the economic equivalent of one share of common stock. Initially the rights will not be exercisable and will trade with our common stock. Generally, the rights may become exercisable if a person or group acquires beneficial ownership of 15% or more of our common stock or commences a tender or exchange offer upon consummation of which such person or group would beneficially own 15% or more of our common stock. When the rights become exercisable, our board of directors has the right to authorize the issuance of one share of our common stock in exchange for each right that is then exercisable.

The primary objective of our investment activities is to preserve principal while at the same time maximize the income we receive from our investments without significantly increasing risk. Some of the securities that we have invested in may be subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing interest rate later rises, the principal amount of our investment will probably decline. To minimize this risk, we maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, other non-government debt securities and money market funds. In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing interest rate. The following table presents the amounts of our cash equivalents and short-term investments that are subject to market risk by range of expected maturity and weighted-average interest rates as of June 29, 2003 and June 30, 2002. This table does not include money market funds because those funds are not subject to market risk.

Currently, all of our sales and the majority of our expenses are denominated in United States dollars and as a result, we have experienced no significant foreign exchange gains and losses to date. While we have conducted some transactions in foreign currencies during the year ended June 29, 2003 and expect to continue to do so, we do not anticipate that foreign exchange gains or losses will be significant, in part because of our foreign exchange risk management process discussed below.

We enter into foreign exchange forward contracts to hedge foreign currency forecasted transactions related to certain operating expenses, denominated in Japanese Yen, the Euro, the Swedish Krona and the British Pound. These derivatives are designated as cash

flow hedges under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended and interpreted (“SFAS 133”). At June 29, 2003, these forward foreign currency contracts had a notional principal amount of $5.4 million (fair value of $96,000). These contracts have maturities of less than 60 days.

Additionally, we enter into foreign exchange forward contracts to mitigate the effect of gains and losses generated by the remeasurement of certain assets and liabilities denominated in Japanese Yen, the Euro, the Swedish Krona and the British Pound. These derivatives are not designated as hedges under SFAS 133. At June 29, 2003, we held foreign currency forward contracts with a notional principal amount of $3.6 million (fair value of $25,000). These contracts have maturities of less than 45 days. Changes in the fair value of these foreign exchange forward contracts are offset largely by remeasurement of the underlying assets and liabilities.

We do not enter into foreign exchange forward contracts for speculative or trading purposes. Foreign currency transaction gains from operations, including the impact of hedging, were $0.4 million in fiscal 2003. Foreign currency transaction losses from operations, including the impact of hedging, were $0.3 million and $0.6 million in fiscal 2002 and fiscal 2001, respectively.

We have historically made investments in several privately held companies. These nonmarketable investments are accounted for under the cost method, as ownership is less than 20 percent and we do not have the ability to exercise significant influence over the operating, financing and investing activities of the investee companies. These investments are inherently risky as the market for the technologies or products they have under development are typically in the early stages and may never materialize. It is possible that we could lose our entire initial investment in these companies. As a part of management’s process of regularly reviewing these investments for impairment, we recorded write-downs of $0.2 million and $9.7 million on certain investments, which were determined to be other than temporarily impaired in fiscal 2003 and fiscal 2002, respectively. At June 29, 2003, the carrying value of our remaining investments was zero.

Extreme Networks, Inc. (“Extreme Networks” or the “Company”) is a leading provider of network infrastructure equipment and markets its products primarily to business, governmental and educational customers with a focus on large corporate enterprises and metropolitan service providers. Extreme Networks was incorporated in California in 1996 and reincorporated in Delaware in 1999.

Our fiscal year is a 52/53-week fiscal accounting year that closes on the Sunday closest to June 30th every year. Fiscal 2003, fiscal 2002 and fiscal 2001 were 52-week fiscal years. All references herein to “fiscal 2003” or “2003” represent the fiscal year ended June 29, 2003.

The consolidated financial statements include the accounts of Extreme Networks and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. Investments in which management intends to maintain more than a temporary 20% to 50% interest, or otherwise has the ability to exercise significant influence, are accounted for under the equity method. Investments in which management has less than a 20% interest and does not have the ability to exercise significant influence are carried at the lower of cost or estimated realizable value.

Assets and liabilities of foreign operations are translated to United States dollars at current rates of exchange, and revenues and expenses are translated using average rates. Foreign currency transaction gains from operations, including the impact of hedging, were $0.4 million in fiscal 2003. Foreign currency transaction losses from operations, including the impact of hedging, were $0.3 million and $0.6 million in fiscal 2002 and fiscal 2001, respectively. Gains and losses from foreign currency translation are included as a separate component of other comprehensive income (loss).

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but are not limited to, the accounting for the allowances for doubtful accounts and returns reserves, inventory valuation, depreciation and amortization, impairment of purchased intangible assets and minority investments, sales returns, warranty accruals and income taxes. Actual results could differ materially from these estimates.

Certain items previously reported in specific financial statement captions have been reclassified to conform to the fiscal 2003 presentation. Such reclassifications have not impacted previously reported revenues, operating loss or net loss. During fiscal 2003, revenue from service arrangements increased to greater than 10% of total net revenues, requiring us to separately report product and service revenues. In order to separately state cost of revenues related to product and service revenues, we reclassified $23.1 million

and $17.8 million of service expenses that had previously been included in operating expenses for fiscal 2002 and fiscal 2001, respectively.

We derive the majority of our revenue from sales of our stackable and chassis-based networking equipment, with the remaining revenue generated from service fees relating to the maintenance and installation of, and training on, our products. Our revenue recognition policy follows SEC Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements. We generally recognize product revenue from our end-user and reseller customers at the time of shipment, provided that persuasive evidence of an arrangement exists, the price of the product is fixed or determinable and collection of the sales proceeds is reasonably assured. When significant obligations or contingencies remain after products are delivered, such as installation or customer acceptance, revenue and related costs are deferred until such obligations or contingencies are satisfied. Revenue from service obligations under maintenance contracts is deferred and recognized on a straight-line basis over the contractual period, which typically ranges from one to five years. When we provide a combination of products and services to customers, revenue is allocated based on the relative fair values.

We make certain sales to partners in two-tier distribution channels. The first tier consists of a limited number of independent distributors that sell primarily to resellers and, on occasion, to end-user customers. Under specified conditions, we grant these distributors the right to return a portion of unsold inventory to us for the purpose of stock rotation. Therefore, we defer recognition of revenue on all sales to distributors until the distributors sell the product, as evidenced by a monthly sales-out report that the distributors provide to us. The second tier of the distribution channel consists of a large number of third-party resellers that sell directly to end-users and are not granted return privileges, except for defective products.

Highly liquid investment securities with insignificant interest rate risk and with original maturities of three months or less at date of purchase are classified as cash equivalents. Investment securities with original maturities greater than three months and remaining maturities of less than one year are classified as short-term investments. Investment securities with remaining maturities greater than one year are classified as marketable securities. Our investments are primarily comprised of United States, state and municipal government obligations and corporate securities.

To date, all marketable securities have been classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported net-of-tax as a separate component of stockholders’ equity. Realized gains and losses on available-for-sale securities are included in interest income. The cost of securities sold is based on specific identification. Premiums and discounts are amortized over the period from acquisition to maturity and are included in investment income, along with interest and dividends.

We have made minority investments in privately held companies. Our interest in these companies was significantly less than 20% and, as such, we did not have the ability to exercise significant influence. We monitor our minority investments for other than temporary impairment and make appropriate reductions in carrying values when necessary. We recorded write-downs of $0.2 million, $9.7 million and $1.8 million during fiscal 2003, fiscal 2002 and fiscal 2001, respectively, related to impairments of our privately held investments. The carrying value of investments in privately held companies was zero as of June 29, 2003.

The carrying amounts and estimated fair values of our financial instruments were as follows (in thousands):

The fair values of short-term investments and marketable securities are determined using quoted market prices for those securities or similar financial instruments. The fair value of the convertible subordinated notes due 2006 is estimated using quoted market prices.

We may be subject to concentration of credit risk as a result of certain financial instruments consisting principally of marketable investments and accounts receivable. We have placed our investments with high-credit quality issuers. We will not invest an amount exceeding 10% of our combined cash, cash equivalents, short-term investments and marketable securities in the securities of any one obligor or maker, except for obligations of the United States government, obligations of United States government agencies and money market accounts.

We perform ongoing credit evaluations of our customers and do not require collateral in exchange for credit. One distributor of our products accounted for 11%, 15% and 16% of our net revenue in fiscal 2003, fiscal 2002 and fiscal 2001, respectively. One customer accounted for 11% of our accounts receivable balance as of June 29, 2003 and two customers accounted for 20% and 15% of our accounts receivable balance as of June 30, 2002.

One supplier currently manufacturers all of our application specific integrated circuits, or ASICs, used in all of our hardware products. Any interruption or delay in the supply of any of these or other single source components, or the inability to procure these components from alternate sources at acceptable prices and within a reasonable timeframe, would have a material adverse effect on our ability to meet customer orders which would negatively impact our business, operating results and financial condition. In addition, qualifying additional suppliers can be time-consuming and expensive, and may increase the likelihood of design or production related errors. We attempt to mitigate these risks by working closely with our ASIC supplier regarding production planning and timing of new product introductions.

We currently derive substantially all of our revenue from sales of our Summit, BlackDiamond and Alpine products. We expect that revenue from these products will account for a substantial portion of our revenue for the foreseeable future. Accordingly, widespread market acceptance of these products is critical to our future success.

Inventories consist of raw materials and finished goods and are stated at the lower of cost or market, on a first-in, first-out basis. We provide inventory allowances based on estimated excess and obsolete inventories determined primarily by future demand forecasts. Inventories consist of (in thousands):

Included in the above allowance is $1.7 million and $11.8 million at June 29, 2003 and June 30, 2002, respectively, related to the restructuring reserve established in fiscal 2001 as discussed in Note 13.

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the assets, with the exception of land, which is not depreciated. Estimated useful lives of 25 years are used for buildings. Estimated useful lives of three to four years are used for computer equipment and software. Estimated useful lives of three years are used for office equipment, furniture and fixtures. Depreciation and amortization of leasehold improvements is computed using the lesser of the remaining lease terms or three years. Property and equipment consist of

Statement of Financial Accounting Standards (“SFAS”) No. 142, Goodwill and Other Intangible Assets (“SFAS 142”), requires goodwill to be tested for impairment on an annual basis and between annual tests in certain circumstances, and written down when impaired, rather than being amortized as previous standards required. Furthermore, SFAS 142 requires purchased intangible assets other than goodwill to be amortized over their useful lives unless these lives are determined to be indefinite. We adopted this statement July 1, 2002. In accordance with SFAS 142, we ceased amortizing goodwill as of July 1, 2002.

In accordance with the transition provisions of SFAS 142, we completed the first step of the transitional goodwill impairment test at July 1, 2002. The results of that test indicated that goodwill was not impaired and that a cumulative impairment loss did not have to be recognized.

In accordance with SFAS 142, we performed the annual impairment review of our goodwill at the end of fiscal 2003. During this evaluation, we noted indicators that the carrying value of our goodwill may not be recoverable due to the prolonged economic downturn affecting our operations and revenue forecasts.

Under the first step of the SFAS 142 analysis, the fair value was determined based on the income approach, which estimates the fair value based on the future discounted cash flows. Based on the first step analysis, we determined that the carrying amount of our goodwill was in excess of its fair value. As such, we were required to perform the second step analysis since it failed the first step test, to determine the amount of the impairment loss. We completed the second step analysis in connection with the impairment review for fiscal 2003 and recorded an impairment charge of $1.0 million. There was no goodwill remaining as of June 29, 2003.

The following table presents the impact of SFAS 142 on net loss and net loss per share had the standard been in effect in fiscal 2002 and fiscal 2001 (in thousands, except per-share amounts):

Long-lived assets, including purchased intangible assets other than goodwill, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets that management expects to hold and use is based on the fair value of the asset. Long-lived assets

to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. At June 29, 2003, there were no purchased intangible assets recorded in our consolidated balance sheet.

Financial Accounting Standards Board (“FASB”) Interpretation No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others (“FIN 45”) requires that upon issuance of a guarantee, the guarantor must disclose and recognize a liability for the fair value of the obligation it assumes under that guarantee. The initial recognition and measurement requirement of FIN 45 is effective for guarantees issued or modified after December 31, 2002. The disclosure requirements of FIN 45 are effective for financial statements of interim or annual periods that end after December 15, 2002. We have determined that the requirements of FIN 45 apply to our standard product warranty, to a guarantee of a lease obligation of one of our contract manufacturers, to letters of credit issued under our line of credit and to indemnification obligations contained in commercial agreements, including customary intellectual property indemnification for our products contained in agreements with our resellers and end-users.

Our standard hardware warranty period is 12 months from the date of shipment to end-users and 14 months from the date of shipment to channel partners, which include resellers and distributors. Upon shipment of products to our customers, including both end-users and channel partners, we estimate expenses for the cost to repair or replace products that may be returned under warranty and accrue a liability for this amount. The determination of our warranty requirements is based on our actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. We estimate and adjust these accruals at each balance sheet date in accordance with changes in these factors. Changes in our warranty accrual for fiscal 2003 and fiscal 2002 are as follows (in thousands):

We have elected to follow APB Opinion No. 25, Accounting for Stock Issued to Employees, in accounting for our employee stock options because, as discussed below, the alternative fair value accounting provided for under SFAS No. 123, Accounting for Stock-Based Compensation, (“SFAS 123”) requires the use of option valuation models that were not developed for use in valuing employee stock options. Under APB No. 25, because the exercise price of our employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized in our financial statements.

Pro forma information regarding net income and earnings per share is required by SFAS 123. This information is required to be determined as if we had accounted for our employee stock options and shares issued under the 1999 Purchase Plan under the fair value method of that statement. The fair value of options granted in fiscal 2003, fiscal 2002 and fiscal 2001 was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted average assumptions:

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in the opinion

of management, the existing models do not necessarily provide a reliable single measure of the fair value of employee stock options. The weighted-average estimated fair value of options granted in fiscal 2003, fiscal 2002 and fiscal 2001 was $3.41, $7.95 and $25.82, respectively. The weighted-average estimated fair value of shares granted under the 1999 Purchase Plan in fiscal 2003, fiscal 2002 and fiscal 2001 was $1.92, $5.55 and $18.91, respectively. Pro forma information regarding net income (loss) and earnings (loss) per share is required by SFAS 123. This information is required to be determined as if we had accounted for shares issued under all of our employee stock options and shares issued under the 1999 Purchase Plan under the fair value method of that statement. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options’ vesting periods. The following pro forma information sets forth our net loss and net loss per share assuming that we had used the SFAS 123 fair value method in accounting for employee stock options and purchases (in thousands, except per share amounts):

Stock compensation expense for options granted to nonemployees has been determined in accordance with SFAS 123 and Emerging Issues Task Force (“EITF”) 96-18, Accounting for Equity Instruments that are Issued to Other Than Employees for Acquiring, or in Conjunction with, Selling Goods or Services, as the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measured. The fair value of options granted to nonemployees is remeasured as the underlying options vest.

We use derivative financial instruments to manage exposures to foreign currency. Our objective for holding derivatives is to use the most effective methods to minimize the impact of these exposures. We do not enter into derivatives for speculative or trading purposes. All derivatives, whether designated in hedging relationships or not, are required to be recorded on the balance sheet at fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. For a derivative designated as a fair value hedge, the gain or loss is recognized in other expense in the period of change together with the offsetting gain or loss on the hedged item attributed to the risk being hedged. For a derivative designated as a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income and, upon occurrence of the forecasted transaction, is subsequently reclassified into the consolidated statement of operations line item to which the hedged transaction relates. The ineffective portion of the gain or loss is reported in other expense immediately.

Cooperative advertising obligations with customers are accrued and the costs expensed in marketing expense at the same time the related revenue is recognized. All other advertising costs are expensed as incurred. Advertising expenses were $ 3.8 million, $6.0 million and $11.0 million for fiscal 2003, fiscal 2002 and fiscal 2001, respectively.

In November 2002, the EITF reached a consensus on Issue No. 00-21, Revenue Arrangements with Multiple Deliverables (“EITF 00-21”). EITF 00-21 provides guidance on how to account for arrangements that involve the delivery or performance of multiple products, services and/or rights to use assets. The provisions of EITF 00-21 will apply to revenue arrangements entered into in fiscal periods beginning after June 15, 2003. We are currently evaluating the effect that the adoption of EITF 00-21 will have on our results of operations and financial condition.

Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity

During fiscal 2001, we acquired two privately held companies in which we previously held minority interests: Optranet, Inc. (“Optranet”), a developer of broadband access equipment, and Webstacks, Inc. (“Webstacks”), a developer of content switching equipment. A related party of ours was a significant investor in Optranet at the time of our initial investment and the subsequent acquisition. In addition, a related party of ours was a significant investor in Webstacks at the time of our initial investment and the subsequent acquisition. In connection with these acquisitions, we acquired all of the outstanding stock and assumed all of the outstanding stock options of the respective acquirees. Both acquisitions were accounted for as purchase business combinations.

During fiscal 2003 and fiscal 2002, we recorded in operating expenses asset impairment charges totaling $1.0 million and $89.8 million, respectively, against the acquired intangible assets and goodwill related to these acquisitions. There was no goodwill remaining as of June 29, 2003.

We recognized deferred stock-based compensation associated with unvested stock options subject to forfeiture issued to employees that were assumed in conjunction with the acquisition of Optranet and Webstacks. See Note 7.

We have a revolving line of credit for $10.0 million with a major lending institution. Borrowings under this line of credit bear interest at the bank’s prime rate. As of June 29, 2003, there were no outstanding borrowings under this line of credit. The line of credit contains a provision for the issuance of letters of credit not to exceed the unused balance of the line. As of June 29, 2003, we had letters of credit totaling $2.1 million. These letters of credit were primarily issued to satisfy requirements of certain of our customers for performance bonds. The line of credit requires us to maintain specified financial covenants related to tangible net worth and liquidity. As of June 29, 2003, we were not in compliance with the tangible net worth covenant and obtained the necessary waiver and expect to be in compliance in future quarters. The line of credit expires on November 30, 2003.

As part of our business relationship with MCMS, Inc. (“MCMS”), the predecessor-in-interest to Plexus Corp., we entered into a $9.0 million operating equipment lease for manufacturing equipment in September 2000 with a third-party financing company; we, in turn, subleased the equipment to MCMS. The equipment lease with the third-party financing company requires us to make monthly payments through September 2005 and to maintain specified financial covenants related to profitability and our cash to debt ratio with which we were in compliance as of June 29, 2003. The liability related to this lease is included in lease commitments on the balance sheet.

We lease office space for our various United States and international sales offices. We sublease certain of our leased facilities to third party tenants. Future annual minimum lease payments under all noncancelable operating leases and future rental income under all noncancelable subleases having initial or remaining lease terms in excess of one year at June 29, 2003 were as follows (in thousands):

Rent expense was approximately $6.3 million, $10.4 million and $11.7 million for fiscal 2003, fiscal 2002 and fiscal 2001, respectively, net of sublease income of $0.1 million, $2.0 million and $3.6 million in the respective periods.

On May 27, 2003, Lucent Technologies, Inc. (“Lucent”) filed suit against Extreme Networks and Foundry Networks, Inc. (“Foundry”) in the United States District Court for the District of Delaware, Civil Action No. 03-508. The complaint alleges willful infringement of U.S. Patent Nos. 4,769,810, 4,769,811, 4,914,650, 4,922,486 and 5,245,607 and seeks a judgment: (a) determining that we have willfully infringed each of the five patents; (b) determining that Foundry has willfully infringed four of the five patents; (c) permanently enjoining us from infringement, inducement of infringement and contributory infringement of each of the five patents; (d) permanently enjoining Foundry from infringement, inducement of infringement and contributory infringement of four of the five patents; and (e) awarding Lucent unspecified amounts of trebled damages, together with expenses, costs and attorneys’ fees.

We are subject to other legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters, including the specific matters discussed above, is currently not determinable, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

In December 2001, we completed a private placement of $200.0 million of convertible subordinated notes. The notes mature in 2006. Interest is payable semi-annually at 3.5% per annum. The notes are convertible at the option of the holders into our common stock at an initial conversion price of $20.96 per share, subject to adjustment. In lieu of issuing common shares, the notes are redeemable in cash at the option of Extreme Networks at an initial redemption price of 101.4% of the principal amount on or after December 2004 if not converted to common stock prior to the redemption date. We have reserved 9,544,260 shares of common stock for the conversion of these notes. Offering costs of $6.5 million are included in other assets and are amortized using the interest method. Each holder of the notes has the right to cause us to repurchase all of such holder’s convertible notes at 100% of the principal amount plus accrued interest upon a change of control of ownership of Extreme Networks, as defined in the notes.

In April 2001, in connection with our Stockholders’ Rights Agreement, we authorized the issuance of preferred stock. The preferred stock may be issued from time to time in one or more series. The board of directors is authorized to provide for the rights, preferences and privileges of the shares of each series and any qualifications, limitations or restrictions on these shares. As of June 29, 2003, no shares of preferred stock were outstanding.

During fiscal 2001, we recorded deferred stock-based compensation expense associated with unvested stock options subject to forfeiture issued to employees assumed in the acquisitions of Optranet and Webstacks with a value of $21.9 million and $2.5 million, respectively (see Note 4). These amounts are being amortized as charges to operations, using the graded method, over the vesting periods of the individual stock options, generally four years. Upon termination of an employee, the amount of expense recognized under the graded vesting method that is in excess of the amount actually earned is reversed. For the year ended June 29, 2003, we reversed $5.3 million of excess compensation expense (including $2.8 million related to forfeitures that occurred in prior years but which, due to oversight, were not accounted for until the fourth quarter of fiscal 2003) related to terminated employees. We do not believe the $2.8 million amount recorded in the fourth quarter of fiscal 2003 was material to the periods in which it should have been recorded. We recorded amortization of deferred stock compensation expense, net of reversals, of $0.7 million, $10.2 million and $4.1 million for fiscal 2003, 2002 and 2001, respectively. At June 29, 2003, Extreme had a total of approximately $1.7 million remaining to be amortized over the corresponding vesting period of each respective stock option.

In April 2001, the board of directors approved a Stockholders’ Rights Agreement (“Rights Agreement”), declaring a dividend of one preferred share purchase right for each outstanding share of common stock, par value $0.001 per share, of Extreme Networks common stock. The Rights Agreement is intended to protect stockholders’ rights in the event of an unsolicited takeover attempt. It is not intended to prevent a takeover of Extreme Networks on terms that are favorable and fair to all stockholders and will not interfere with a merger approved by the board of directors. In the event the rights become exercisable, each right entitles stockholders to buy, at an exercise price of $150 per right owned, a unit equal to a portion of a new share of Extreme Networks Series A preferred stock. The

rights will be exercisable only if a person or a group acquires or announces a tender or exchange offer to acquire 15% or more of our common stock. The rights, which expire in April 2011, are redeemable for $0.001 per right at the approval of the board of directors.

On March 25, 2003, we filed a Tender Offer Statement on Schedule TO with the Securities and Exchange Commission related to a voluntary stock option exchange program for our employees. Our executive officers, directors and sales executives who report directly to the Vice President, Worldwide Sales were not eligible to participate in this program. Under the program, eligible employees were given the opportunity to voluntarily cancel unexercised vested and unvested stock options previously granted to them that had an exercise price greater than $12.00. The cancelled options were exchanged for replacement stock options to be granted at a future date. For each option for five shares tendered for cancellation, a new option for three shares will be granted to employees who elected to participate in the option exchange program. The replacement stock options will be granted with an exercise price equal to the fair market value of our stock on the date of grant, which is scheduled to be October 23, 2003. In order to receive new stock options, an employee must remain employed by us or by one of our subsidiaries until the date when the replacement options are granted. Participants who elected to exchange any options were required to exchange all eligible options and were also required to exchange any other options granted to him or her in the previous six months. The replacement stock options will vest 25% on October 23, 2003 and the remaining 75% of the replacement stock options vest monthly over 24 to 36 months based on the employee’s hire date. Options for approximately 9.3 million shares of common stock were accepted for exchange under this program and, accordingly, were canceled on April 22, 2003.

The following are the components of accumulated other comprehensive income, net of tax (in thousands):

In January 1999, the board of directors approved the adoption of Extreme Network’s 1999 Employee Stock Purchase Plan (the “Purchase Plan”). A total of 4,000,000 shares of common stock have been reserved for issuance under the Purchase Plan. The Purchase Plan permits eligible employees to acquire shares of our common stock through periodic payroll deductions of up to 15% of total compensation. No more than 1,250 shares may be purchased on any purchase date per employee. Each offering period has a maximum duration of 12 months. The price at which the common stock may be purchased is 85% of the lesser of the fair market value of our common stock on the first day of the applicable offering period or on the last day of the respective purchase period. Through June 29, 2003, 2,809,315 shares had been purchased under the Purchase Plan.

In January 1999, the board of directors approved an amendment to the 1996 Stock Option Plan (the “1996 Plan”) to (i) increase the share reserve by 10,000,000 shares, (ii) to remove certain provisions which are required to be in option plans maintained by California privately-held companies and (iii) to rename the 1996 Plan as the “Amended 1996 Stock Option Plan.”

Under the 1996 Plan, which was originally adopted in September 1996, options may be granted for common stock, pursuant to actions by the board of directors, to eligible participants. A total of 50,586,572 shares have been reserved under the 1996 Plan. Options granted are exercisable as determined by the board of directors. Options vest over a period of time as determined by the board of directors, generally four years. The term of the 1996 Plan is ten years. As of June 29, 2003, 22,340,159 shares were available for future grant under the 1996 Plan.

In March 2000, the board of directors adopted the 2000 Nonstatutory Stock Option Plan (the “2000 Plan”). Options may be granted for common stock, pursuant to actions by the board of directors, to eligible participants. Generally, only non-officer employees are eligible to participate in this stock plan, except that options may be granted to officers under this plan in connection with written offers of employment. A total of 4,000,000 shares have been reserved under the 2000 Plan. Options vest over a period of time as determined by the board of directors, generally four years. The term of the 2000 Plan is ten years. As of June 29, 2003, 3,721,599 shares were available for future grant under the 2000 Plan.

In May 2001, the board of directors adopted the 2001 Nonstatutory Stock Option Plan (the “2001 Plan”). Options may be granted for common stock, pursuant to actions by the board of directors, to eligible participants. Generally, only non-officer employees are eligible to participate in this stock plan, except that options may be granted to officers under this plan in connection with written offers of employment. A total of 4,000,000 shares have been reserved under the 2001 Plan. Options vest over a period of time as determined by the board of directors, generally four years. The term of the 2001 Plan is ten years. As of June 29, 2003, 1,075,585 shares were available for future grant under the 2001 Plan.

During fiscal 2003, we granted restricted stock awards under the 2001 Plan for 85,000 shares of common stock to a number of technical employees. The shares were placed in an escrow account and will be released to the recipients as the shares vest over twenty-three months. If a participant terminates employment prior to the vesting dates, the unvested shares will be canceled and returned to the 2001 Plan. We will recognize compensation expense on the awards in research and development expense based on an intrinsic value calculation as the shares vest.

In connection with the acquisitions of Optranet and Webstacks, we assumed the stock option plans of each company. During fiscal 2001, approximately 608,401 and 115,676 shares of our common stock were reserved for issuance under the assumed plans of Optranet and Webstacks, respectively, and the related options have been included as granted in fiscal 2001 in the preceding table. Options to purchase approximately 82,356 shares of common stock have been exercised under the Optranet plan as of June 29, 2003 but are subject to repurchase until vested. Options to purchase approximately 134,258 shares of common stock have been exercised under the Webstacks plan as of June 29, 2003 but are subject to repurchase until vested.

The following table summarizes significant ranges of outstanding and exercisable options at June 29, 2003:

Options to purchase 11,523,895 shares were exercisable at June 30, 2002 with a weighted-average exercise price of $17.56.

We provide a tax-qualified employee savings and retirement plan, commonly known as a 401(k) plan (the “Plan”), which covers our eligible employees. Pursuant to the Plan, employees may elect to reduce their current compensation up to the lesser of 80% or the statutorily prescribed limit of $12,000 for calendar year 2003. Effective January 1, 2003, employees age 50 or over may elect to contribute an additional $2,000. For calendar year 2002, employees were able to elect to reduce their current compensation up to the lesser of 80% or the statutorily prescribed limit of $11,000. For calendar year 2001, employees were able to elect to reduce their current compensation up to the lesser of 20% or the statutorily prescribed limit of $10,500. The amount of the reduction is contributed to the Plan on a pre-tax basis.

We provide for discretionary matching contributions as determined by the board of directors for each calendar year. As of September 2000, the board of directors set the match at $0.25 for every dollar contributed by the employee up to the first 4% of pay. The same level of match was continued during the 2001 and 2002 calendar years. All matching contributions vest immediately effective September 2000. In addition, the Plan provides for discretionary contributions as determined by the board of directors each year. Our matching contributions to the Plan totaled $484,010, $503,051 and $378,391 for fiscal 2003, fiscal 2002 and 2001, respectively. No discretionary contributions were made in fiscal 2003, 2002 or 2001.

The provision for (benefit from) income taxes for fiscal 2003, fiscal 2002 and fiscal 2001 consisted of the following (in thousands):

Pretax income (loss) from foreign operations was $2.5 million, $8.9 million and $0.6 million in fiscal 2003, fiscal 2002 and fiscal 2001, respectively.

The difference between the provision (benefit) for income taxes and the amount computed by applying the federal statutory income tax rate (35 percent) to income (loss) before taxes is explained below (in thousands):

Significant components of our deferred tax assets are as follows (in thousands):

In fiscal 2003, our valuation allowance increased by $163.1 million to provide a valuation allowance against all of our federal and state deferred tax assets. The valuation allowance is determined in accordance with the provisions of Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes, (“SFAS 109”) which requires an assessment of both negative and positive evidence when measuring the need for a valuation allowance. Our losses in recent periods represented sufficient negative evidence to require a valuation allowance under SFAS 109. This valuation allowance will be evaluated periodically and can be reversed partially or totally if business results have sufficiently improved to support realization of our deferred tax assets.

As of June 29, 2003, we had net operating loss carryforwards for federal and state tax purposes of $191.6 million and $28.7 million, respectively. We also had federal and state tax credit carryforwards of $8.6 million and $8.3 million, respectively. Unused net operating loss and tax credit carryforwards will expire at various dates beginning in the years 2004 and 2007, respectively.

Utilization of the net operating losses and tax credits may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and tax credits before utilization.

Our income taxes payable for federal and state purposes have been reduced, and the deferred tax assets increased by the tax benefits associated with dispositions of employee stock options. We receive an income tax benefit calculated as the difference between the fair market value of the stock at the time of exercise and the option price, tax effected. These benefits were credited directly to the stockholders’ equity and amounted to $1.1 million and $45.0 million for fiscal 2002 and fiscal 2001, respectively. Benefits reducing taxes payable amounted to $8.6 million for fiscal 2001. Benefits increasing gross deferred tax assets amounted to $1.1 million and $36.4 million for fiscal 2002 and fiscal 2001, respectively.

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision makers with respect to the allocation of resources and performance.

We operate in one segment, the development and marketing of network infrastructure equipment. We conduct business globally and are managed geographically. Revenue is attributed to a geographical area based on the location of the customers.

Substantially all of our assets were attributable to United States operations at June 29, 2003 and June 30, 2002.

Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of options, warrants, convertible subordinated notes and convertible securities. Dilutive earnings per share is calculated by dividing net income by the weighted average number of common shares used in the basic earnings (loss) per share calculation plus the dilutive effect of options, warrants, convertible subordinated notes and convertible securities. Diluted net loss per share was the same as basic net loss per share in fiscal 2003, fiscal 2002 and fiscal 2001 because we had net losses in those periods. The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):

The following table sets forth potential shares of common stock that are not included in the diluted net loss per share calculation above because to do so would be antidilutive for the periods (in thousands):

SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities (“SFAS 133”) as amended and interpreted requires that all derivatives be recorded on the balance sheet at fair value. Changes in the fair value of derivatives that do not qualify, or are not effective as hedges must be recognized currently in earnings. Accordingly, we record the forward contracts used to manage foreign exchange exposures on the balance sheet at fair value.

Foreign Exchange Exposure Management – We denominate global sales in US dollars. International sales subsidiaries generate operating expenses in foreign currencies. In the first quarter of fiscal 2002, we initiated a program of hedging forecasted and actual foreign currency risk with forward contracts to eliminate, reduce or transfer selected foreign currency risks that can be confidently identified and quantified. Hedges of anticipated transactions are designated and documented at inception as cash flow hedges and are evaluated for effectiveness at least quarterly. As the critical terms of the forward contract and the underlying are matched at inception, forward contract effectiveness is calculated by comparing the cumulative change in the contract (on a forward to forward basis) to the change in fair value of the anticipated expense, with the effective portion of the hedge recorded in accumulated other comprehensive income (“OCI”). Values accumulated in OCI are subsequently reclassified into the consolidated statement of operations line item to which the hedged transaction relates in the period the anticipated expense is recognized in income. Any ineffectiveness is recognized immediately in other expense. No ineffectiveness was recognized in other expense in fiscal 2003 and fiscal 2002.

Forward contracts used to hedge the remeasurement of non-functional currency monetary assets and liabilities are recognized in other expense currently to mitigate reported foreign exchange gains and losses.

13. Restructuring Charges, Property and Equipment Write-Off and Provision for Inventory

During fiscal 2003, we recorded restructuring charges of $15.9 million. The restructuring charges included excess facilities charges of $9.6 million, severance charges of $4.4 million and asset impairments of $1.9 million. The excess facilities charge represents an increase to the charge recognized during fiscal 2002 for the domestic and international facilities discussed below. The commercial real estate market has continued to deteriorate since the initial charge was recorded in the third quarter of fiscal 2002, necessitating an increase in reserves that takes into consideration the unfavorable difference between lease obligation payments and projected sublease receipts. The actual cost could differ from this estimate, and additional facilities charges could be incurred if we are unsuccessful in negotiating reasonable termination fees on certain facilities, if facility operating lease rental rates continue to decrease in these markets, if it takes longer than expected to find a suitable tenant to sublease these facilities or if other estimates and assumptions change. Severance charges of $2.7 million related to a reduction in total staff during the second quarter of fiscal 2003 of approximately 100 people, or 10% of the total workforce, across all departments. Severance charges of $1.7 million related to a reduction in total staff announced at the end of the fiscal year of approximately 70 people, or 8% of the total workforce, across all departments. The asset impairment charge relates to the write-off of leasehold improvements and office furniture related to excess facilities.

In June 2000, we entered into two operating lease agreements for approximately 16 acres of land and the accompanying 275,000 square feet of buildings to house our primary facility in Santa Clara, California (the “Property”). The two lease agreements required the purchase of the Property for $80.0 million at the end of the lease term and provided the option to purchase the Property at any time

during the lease term. In fiscal 2002, we exercised the option to purchase the Property and title to the Property was transferred to us. The charge of $39.0 million represented the difference between the purchase price and the appraised value of the land and buildings at the time of exercise of the option to purchase the Property.

The excess facility charges of $25.4 million in fiscal 2002 are the result of our decision to permanently reduce occupancy or vacate certain domestic and international facilities. The estimated facilities costs were based on current comparable rates for leases in the respective markets or estimated termination fees. We anticipate that we will continue to make cash outlays to meet lease obligations for these facilities in accordance with their terms, unless estimates and assumptions change or we are able to negotiate acceptable lease terminations prior to the anticipated termination dates for the applicable leases. The asset impairment charge of $ 9.1 million represented the unamortized amount of the assets at the date a decision was made to discontinue use. These assets were not utilized subsequently or held for sale. They were either scrapped or abandoned.

During the second quarter of fiscal 2003, we completed a property and equipment physical inventory in conjunction with the implementation of our new ERP system. The property and equipment physical inventory resulted in the identification of $12.7 million of property and equipment whose fair value was determined to be zero because the assets were either no longer in service or were not identifiable. Therefore these assets were written off during the second quarter of fiscal 2003.

As a result of the rapid change in the market for networking products, we recorded $5.0 million and $39.2 million in charges for excess and obsolete inventory and non-cancelable purchase commitments in fiscal 2002 and fiscal 2001, respectively. The following is a summary of the additional excess inventory allowance from the third quarter of fiscal 2001 to June 29, 2003 (in thousands)

We have audited the accompanying consolidated balance sheets of Extreme Networks, Inc. as of June 29, 2003 and June 30, 2002, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended June 29, 2003. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Extreme Networks, Inc. at June 29, 2003 and June 30, 2002, and the consolidated results of its operations and its cash flows for each of the three years in the period ended June 29, 2003, in conformity with accounting principles generally accepted in the United States. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

As discussed in Note 2 to the consolidated financial statements, in 2003, Extreme Networks, Inc. changed its method of accounting for goodwill and other intangible assets in accordance with guidance provided in Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets.”
