Overview

Extreme Networks, Inc. ("Extreme" or "the Company") is a leading provider of
a next generation of switching solutions that meet the increasing needs of
enterprise local area networks, or LANs, internet service providers, or ISPs,
and content providers. The key advantages of our Layer 3 switching solutions
are increased performance, the ability to easily grow, or "scale," in size as
customer needs change, flexible allocation of network resources, ease of use
and lower cost of ownership. These advantages are obtained through the use of
custom semiconductors, known as ASICs, in our products and through hardware and
software designs that are common and uniform across our product line. The
routing of network traffic, a function referred to as Layer 3 switching, is
done primarily with ASICs in our products, and consequently, is faster than the
software implementations used in many competing products. Traditional Layer 3
products rely primarily on software which can slow traffic speeds below those
which could otherwise be achieved and result in message packets being lost when
network traffic is high. Our products incorporate an ASIC-based, wire-speed
architecture and are designed to avoid the loss of message packets in the
switch, or "non-blocking." As a result, our products are less expensive than
software-based routers, yet offer improved performance throughout the network
from the core to the desktop. The Dell'Oro Group, a research and consulting
firm, estimates in an independently prepared market report dated July 1999,
that the market for Layer 3 switching totaled $637 million in 1998 and is
expected to increase to approximately $3.8 billion in 2001.

Industry Background

Businesses and other organizations have become increasingly dependent on
networks as their central communications infrastructure to provide connectivity
for internal and external communications. New mission-critical computing
applications, such as enterprise resource planning, large enterprise databases
and sophisticated on-line connections with vendors, as well as the increased
use of traditional applications, such as e-mail, require significant
information technology resources. The emergence of the desktop browser as a
user interface has enabled bandwidth-intensive applications that contain voice,
video and graphics to be used extensively through intranets and externally
through extranets. These new applications, combined with the growth in
business-to-business e-commerce and other on-line transactions, are further
burdening the network infrastructure.

Today's Networking Environments

LANs. LANs have traditionally been designed for client/server applications,
where traffic patterns were predictable and traffic loads are relatively
stable. In this environment, the majority of traffic remained within a given
workgroup, with only a small percentage traveling across the high traffic
portion of a LAN which interconnects all or a large part of the LAN. The
increased use of data-intensive, mission-critical applications, the widespread
implementations of intranets and extranets, and the ubiquity of Internet
technologies have

3


created unpredictable traffic patterns, and unpredictable traffic loads within
the LAN. In addition, as users utilize the desktop browser and Internet
technologies to access significant amounts of information from servers located
inside and outside of the organization, a much higher percentage of traffic
crosses the enterprise LAN backbone. For example, an employee can make a simple
request that may require data to be downloaded and analyzed from multiple data
warehouses outside his or her local workgroup, resulting in increased traffic
across the LAN. Similarly, multiple users could request a multimedia
presentation from a company intranet or from the Internet consuming tremendous
amounts of network capacity. Either of these situations could result in users
overwhelming a company's enterprise LAN unknowingly. As a result, the increased
traffic, bandwidth-intensive applications and unpredictable traffic patterns
are straining traditional LAN environments and reducing the performance of
mission-critical applications.

Early LANs supported limited numbers of users and used a variety of
protocols to organize the transmission of data, including Ethernet, Token Ring
or AppleTalk technologies. As the number of users and the amount of traffic on
a network grew, network performance began to decline. In this shared
environment, each desktop received and was burdened by the communication of
every other desktop. The need to improve network performance was initially
addressed by adding network devices known as bridges or hubs that separated the
entire LAN into smaller workgroups. This arrangement was effective in
supporting the traditional client/server environment where the majority of
traffic remained within the workgroup. As applications became more bandwidth-
intensive and users increasingly communicated outside of their workgroup,
bridges and hubs were unable to process this traffic effectively. To mitigate
this problem, Layer 2 switches were developed to provide a dedicated link for
each desktop and eliminate the unnecessary flow of information to every
desktop. In addition to the evolution of new devices, the need for increased
backbone speeds led to the development of new and faster technologies such as
FDDI, Fast Ethernet and ATM. However, each of these technologies employs
different protocols, further complicating the LAN by requiring software-based
routers that use expensive CPUs and software tables to route this multi-
protocol traffic. Today, it is not uncommon to find multiple protocols and
devices across the four basic areas of the network:

. the desktop, which connects end users;

. the segment, which interconnects networking devices;

. the server, which connects servers to the network; and

. the network core, which consists of the enterprise backbone that
interconnects LAN segments.

A network must be scalable in the following four dimensions:

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. Hence, the backbone and server connections that
aggregate traffic from desktops require speeds well 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 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 grew basically in line with
the number of users on the network. With today's data-intensive applications
accessed in random patterns from within and outside of the network, users can
spike traffic unpredictably, consuming significant bandwidth to the detriment
of other users.

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 connecting and
supporting up to thousands, and even tens of thousands, of users and servers
while providing performance and reliable connectivity.


4


Quality of service. Quality of service refers to the ability to control the
delivery of traffic based upon its level of importance. Mission-critical
enterprise and delay-sensitive multimedia applications 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, true end-to-end quality of service would
allocate bandwidth to specified applications.

Opportunity for Next Generation Switching Solutions

The emergence of several technology trends is enabling a new generation of
networking equipment that can meet the four scalability dimensions of today's
enterprise LANs, ISPs and content providers by accommodating new unpredictable
traffic patterns and bandwidth-intensive, mission-critical applications. First,
while many new and different technologies have been deployed in existing LANs,
Ethernet has become the predominant LAN technology, with over 95% of the market
in 1998 and total shipments of over 350 million ports from 1991 to 1998,
according to the Dell'Oro Group. Ethernet has evolved from the original 10 Mbps
Ethernet to 100 Mbps Fast Ethernet and, in 1998, to 1,000 Mbps Gigabit
Ethernet. Gigabit Ethernet represents a viable network backbone protocol,
enabling 100 Mbps Fast Ethernet connections to the desktop to be aggregated for
network backbone transport across the network core. Second, growth of the
Internet and the subsequent development of applications based on Internet
technologies have increased the use of the Internet Protocol.

With the wide acceptance of Ethernet and Internet Protocol-based
technologies, the need to support a multi-protocol environment is diminished.
As a result, the simplified routing functionality can be embedded in
application specific integrated circuits, or ASICs, instead of in the software
and CPUs used in multi-protocol software-based routers. The resulting device,
called a Layer 3 switch, functions as a less expensive and significantly faster
hardware-based router. The Dell'Oro Group estimates in an independently
prepared July 1999 market report, that the market for Layer 3 switching totaled
$637 million in 1998 and is expected to increase to approximately $3.8 billion
in 2001. Layer 3 switches can operate at gigabit speeds and, as hardware
routers, can support large networks. However, most Layer 3 switches still block
traffic in high utilization scenarios and can only support standards-based
traffic prioritization quality of service. While Layer 3 switching dramatically
increases network performance, many of today's offerings fail to realize the
potential of this technology because of the use of inconsistent hardware,
software and management architectures.

To effectively address the needs of today's enterprise LANs, ISPs and
content providers customers need a solution that is easy to use and implement
and can scale in terms of speed, bandwidth, network size and quality of
service. Layer 3 switching represents the next critical step in addressing
these requirements. However, enterprises need a Layer 3 solution that provides
sufficient bandwidth to support unpredictable traffic spikes without impacting
all other users connected to the network. In addition, enterprises require a
quality of service solution that supports industry-standard prioritization and
enables network administrators to offer quality of service that maps business
processes and network policies. Finally, to simplify their networks,
enterprises need a family of interoperable devices that utilize a consistent
hardware, software and management architecture. Through an integrated family of
products, network managers can effectively deploy the solution at any point in
the network and follow a migration path to a network implemented with a
consistent architecture from end-to-end.

The Extreme Networks Solution

Extreme provides end-to-end network switching solutions that meet the
requirements of enterprise LANs, ISPs and content providers by providing
increased performance, scalability, policy-based quality of service, ease of
use and lower cost of ownership. Our products share a common ASIC, software and
network management architecture that enables Layer 3 switching at wire speed in
each of the desktop, segment, server and core areas of the enterprise LAN. In
addition, these products can be utilized by ISPs and content providers for
their web-hosting and server co-location operations. Because our products are
based on industry standard routing and network management protocols, they are
interoperable with existing network infrastructures. We

5


offer policy-based quality of service that controls the delivery of network
traffic according to pre-set policies that specify priority and bandwidth
limits. All of our switches include integrated web server software that allows
the switch to be managed from any browser-equipped desktop. In addition, our
Java-based enterprise management software utilizes integrated web server
software that allows simplified management from any locally connected computer,
or remotely over the Internet.

The key benefits of Extreme's solutions are:

High performance. Our products provide 1,000 Mbps Gigabit Ethernet to the
network core and Fast Ethernet to the desktops, segments and servers, together
with the non-blocking, wire-speed routing of our ASIC-based Layer 3 switching.
Using our products, customers can achieve forwarding rates that are up to 100
times faster than with software-based routers.

Ease of use and implementation. Our products share a common ASIC, software
and network management architecture and offer consistent features for each of
the key areas of the network. Our standard-based products can be integrated
into and installed within existing networks. Customers can upgrade with Extreme
products without needing additional training. ExtremeWare software simplifies
network management by enabling customers to manage any of our products remotely
through a browser interface.

Scalability. Our solutions offer customers the speed and bandwidth they need
today with the capability to scale their networks to support demanding
applications in the future without the burden of additional training or
software or system complexity. Customers who purchase our products can upgrade
them to advanced Layer 3 capability because this functionality is built into
our ASICs. ExtremeWare Enterprise Manager software simplifies software upgrades
by allowing the network manager to upgrade all Extreme switches simultaneously.

Quality of service. Extreme's policy-based quality of service enables
customers to prioritize mission-critical applications by providing 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 delivery of traffic from specific applications in
accordance with specific policies that are set by the customer. The quality of
service functionality of our ASICs allows our policy-based quality of service
to be performed at wire speed. In addition to providing priority, customers can
allocate specified amounts of bandwidth to specific applications or users.

Lower cost of ownership. Our products are less expensive than software-based
routers, yet offer higher routing performance. Because they share a common
hardware, software and management architecture, we believe our products can
substantially reduce the cost and complexity of network management and
administration. This uniform architecture creates a simpler network
infrastructure which leverages the knowledge and resources businesses have
invested in Ethernet and the Internet Protocol, thereby requiring fewer
resources and less time to maintain.

The Extreme Networks Strategy

Extreme's objective is to be the leading supplier of end-to-end network
solutions. The key elements of our strategy include:

Provide 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 switching environments in
enterprise LANs, ISPs and content providers. Our products provide customers
with 1,000 Mbps Gigabit Ethernet and the wire speed, non-blocking routing
capabilities of ASIC-based Layer 3 switching. We intend to capitalize on our
expertise in Ethernet, IP and switching technologies to develop new products
based on our common architecture that meet the future requirements of
enterprise LANs, ISPs and content providers. These products will offer higher
performance with more advanced functionality and features while continuing to
reduce total cost of ownership for our customers.

6


Expand market penetration. We are focused on product sales to new customers
across market segments, including ISPs, content providers and metropolitan area
networks, or MANs, and on extending our product penetration within existing
customers' networks. Once a customer buys our products for one area of their
network, our strategy is to then offer that customer products for other areas.
As additional products are purchased, a customer obtains the increased benefits
of our end-to-end 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 our custom ASICs and software and includes our wire-speed, Layer 3
switching, policy-based quality of service, routing protocols and ExtremeWare
software. We intend to invest our engineering resources in ASIC and software
development and provide leading edge technologies to increase the performance
and functionality of our products. We also intend to maintain our active role
in industry standards committees such as IEEE and IETF.

Leverage and expand multiple distribution channels. We distribute our
products primarily through resellers and selected OEMs and through our field
sales team. To quickly reach a broad, worldwide audience, we have more than 130
resellers in 40 countries, including regional networking system resellers,
network integrators and wholesale distributors, and have established
relationships with select OEMs. We maintain a field sales force primarily to
support our resellers and to focus on select strategic and large accounts. We
intend to increase the size of our reseller programs and are developing two
tier distribution channels in some regions. To complement and support our
domestic and international reseller and OEM channels, we expect to increase our
worldwide field sales force.

Provide high-quality customer service and support. We seek to enhance
customer satisfaction and build customer loyalty through the quality of our
service and support. We offer a wide range of standard support programs that
include emergency telephone support 24 hours a day, seven days a week and
advanced replacement of products. In addition, we have designed our products to
allow easy service and administration. For example, we can access all of our
switches remotely through a standard web browser to configure, troubleshoot and
help maintain our products. We intend to continue to enhance the ease of use of
our products and invest in additional support services by increasing staffing
and adding new programs for our OEMs and resellers. In addition, we also are
committed to providing customer-driven product functionality through feedback
from key prospects, consultants, channel and OEM partners and customer surveys.

Products

Extreme provides end-to-end switching solutions that meet the requirements
of enterprise LANs, ISPs and content providers by providing increased
performance, scalability, policy-based quality of service, ease of use and
lower cost of ownership. Our Summit and BlackDiamond switches share a common
ASIC, software and management architecture that facilitates a relatively short
product design and development cycle, thereby reducing the time-to-market for
new products and features. This common architecture enables customers to build
an end-to-end enterprise LAN switching solution that has consistent
functionality, performance and management to each of the desktop, segment,
server and core areas of the LAN. The common architecture and end-to-end
functionality of our products also reduces the cost and complexity of network
administration and management.

Our products include two browser-based software application suites,
ExtremeWare and ExtremeWare Policy Manager, that enable simple and efficient
switch management and configuration. ExtremeWare is a standards-based software
suite that delivers policy-based quality of service and enables
interoperability with legacy switches and routers. ExtremeWare Policy Manager
is an application suite that enables remote configuration and management of
multiple switches from a single network station.

Desktop Switches

The enterprise desktop is the portion of the network where individual end-
user workstations are connected to a hub or switch. Traditionally, a discrete
group of desktop users, or a workgroup, shared a single hub, which connected
their workgroup to the rest of the network. In this shared environment, each
desktop in the workgroup receives and is burdened by the communication of every
other desktop in the workgroup. This topology is effective so long as the
majority of traffic remains within the workgroup. As applications have become
more bandwidth intensive and as user traffic has migrated outside the workgroup
via the Internet or an intranet or extranet, however, the hubs are unable to
effectively process this traffic, resulting in diminished desktop performance.
Replacing the hub with a Layer 3 switch alleviates this problem by providing a
dedicated link for each desktop and eliminating unnecessary broadcasts of
information to every desktop in the workgroup. Enterprise desktop switching
provides the desktop with features typically found only at the network core,
such as redundancy, greater speed and the ability to aggregate multiple switch
ports into a single high-bandwidth connection.

We became an industry leader in Layer 3 switching for the desktop with the
introduction of our Summit48 and Summit24 desktop switching products. The
Summit48 addresses high-density enterprise desktop

8


connections. This switch features a non-blocking architecture to avoid the loss
of data packets. The Summit24, with half the number of ports of the Summit48,
is targeted at local wiring closets with moderately dense desktop connections.

Segment Switches

Enterprise segment switching involves the switching among workgroups of
multiple network desktops. While enterprise segment switching faces the same
challenges as desktop switching, it must also address increased congestion from
traffic generated by hubs and other devices that enterprises use to connect
multiple desktop computers. Our primary product for enterprise segment
switching is the chassis-based BlackDiamond. The BlackDiamond chassis addresses
the needs of enterprises that interconnect high-density 10/100 Mbps segments.
It can also be equipped with switched Gigabit Ethernet connectivity modules to
provide high-speed uplinks to servers and switches in the network core.

Server Switches

Servers run the applications and store the data needed by all network end-
users. In a traditional LAN, most of the network resources needed by any given
desktop user, such as printer servers, file servers or database servers, are on
the same workgroup segment as the desktop user. The traditional network
architecture has been shifting toward more centralized server clusters, or
server farms, which require the physical deployment of multiple servers in a
single central data center. This new architecture is easier to manage and can
be configured in a redundant fashion, thereby reducing the risk of system
failure. Additionally, remote offices and telecommuters can access the same
server-based data as desktop users, increasing the flexibility of the network
to support users wherever they may be located.

As more people access the network and as server requests increasingly
involve more bandwidth-intensive applications, network traffic to and from
servers has increased dramatically, causing bandwidth to be consumed by
traffic. Servers also communicate with each other, creating a high volume of
server-to-server traffic within the server farm. Recent technology developments
allow enterprises to install network interface cards that enable connections
using Gigabit Ethernet or the aggregation of multiple 100 Mbps ports on a
single card. This development increases the communication speed of the servers.
In turn, these servers have created the need for switches that can support
their higher server-to-server and server-to-end-user communications speeds. Our
Summit 4 product addresses server switching constraints by providing switched
Gigabit Ethernet and multiple 100 Mbps links to the servers, thereby delivering
sufficient bandwidth between servers and to clients on attached segments. The
BlackDiamond may also be configured to address the needs of a server switching
environment that requires higher port density and modular configuration
flexibility.

Core Switches

The network core is the most critical point in the network, as it is where
the majority of network traffic, including desktop, segment and server traffic,
converges. Network core switching involves switching traffic from the desktops,
segments and servers within the network. Because of the high-traffic nature of
the network core, wire-speed Layer 3 switching, scalability, a non-blocking
hardware architecture, fault-tolerant mission-critical features, redundancy,
link aggregation, the ability to support a variety of high-density "speeds and
feeds" and the ability to accommodate an increasing number of high-capacity
backbone connections are critical in core switching. Our network core products
satisfy these criteria and include the BlackDiamond, the Summit1 and the Summit
Virtual Chassis.

The BlackDiamond switch includes the fault-tolerant features associated with
mission-critical enterprise-class Layer 3 switching, including redundant system
management and switch fabric modules, hot-swappable modules and chassis
components, load-sharing power supplies and management modules, up to four 10
Mbps, 100 Mbps, or 1,000 Mbps aggregated links, dual software images and system
configurations, spanning tree and multipath routing, and redundant router
protocols for enhanced system reliability. In addition, our Summit1

9


switch, which interconnects multiple Gigabit Ethernet backbones from various
parts of the network, is well-suited for network core applications that require
lower density backbone connections. The Summit Virtual Chassis is a high-speed
external backplane that interconnects multiple Summit or BlackDiamond switches.
The Summit Virtual Chassis enables network flexibility by interconnecting
geographically dispersed or co-located Summit and BlackDiamond switches,
thereby creating a distributed core.

ExtremeWare

Our ExtremeWare software suite is pre-installed on every Summit and
BlackDiamond switch. For Extreme switches that are Layer 3 enabled, ExtremeWare
delivers policy-based quality of service capabilities and supports a range of
routing protocols that enable interoperability with legacy switches and
routers. Our policy-based quality of service also enables network managers to
define numerous levels of control, or policies, that determine the amount of
bandwidth available to a group of users or network devices at a given time. The
policies can describe traffic based on port number, protocol type, VLAN, or
Layer 2, Layer 3 or Layer 4 information. Using 802.1p and 802.1Q for VLAN
tagging, policy-based quality of service is passively signaled across the
network to enable standards-based interoperability. For Extreme switches that
are Layer 2 enabled, ExtremeWare provides policy-based quality of service and
supports a range of standards-based management and Layer 2 protocols. In
addition, the basic Layer 3 version of ExtremeWare can be upgraded to advanced
Layer 3 via software that may be downloaded from the web.

ExtremeWare Policy Manager

ExtremeWare Policy Manager simplifies the task of managing and configuring
groups of our switches. With ExtremeWare Policy Manager, an entire network of
our switches can be managed from a single management console using a standard
web browser. This enterprise-wide management enables VLANs and policy-based
quality of service to be established and managed for the entire LAN.
ExtremeWare Policy Manager can also manage centralized and distributed stacks
of Summit switches and the Summit Virtual Chassis as aggregated entities.
ExtremeWare Policy Manager can be accessed using any Java-enabled browser. The
ExtremeWare Policy Manager application and database support both Microsoft
Windows NT and Sun Microsystems' Solaris. The ExtremeWare Policy Manager client
can be launched from within the HP OpenView Network Node Manager application.
In May 1999, we introduced our Enterprise Policy System, a multi-vendor policy
system providing layer independent policy enforcement, address mapping
capability and multi-vendor support.

Sales, Marketing and Distribution

Extreme's sales and marketing strategy is focused on domestic and
international resellers, OEMs and field sales.

Resellers. We have entered into agreements to sell our products through more
than 130 resellers in 40 countries. Our 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. We intend to increase the number of our reseller
relationships, to target vertical markets and support a two-tier distribution
channel.

OEMs. We have established four key OEM relationships with leaders in the
telecommunications, personal computer and computer networking industries. For
fiscal 1999, sales to our OEMs accounted for 20% of our net revenue. Compaq,
which is both an OEM and an end-user customer, accounted for 21% of our net
revenue in fiscal 1999. We intend to maintain a limited number of relationships
with key strategic OEMs who may offer products or distribution channels that
compliment ours. Each of our OEMs resells our products under its own name. We
believe that our OEM relationships enhance our ability to sell and provide
support to large organizations because certain end-user organizations may
prefer to do business with very large suppliers. We anticipate that OEM sales
will decline as a percentage of net revenue as we expand our reseller and
fields sales efforts.

Field sales. We have designed and established 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:

. assists end-user customers in finding solutions to complex network system
and architecture problems;

. differentiates the features and capabilities of our products from
competitive offerings;

. continually monitors and understands the evolving networking needs of
enterprise customers;

. promotes our products and ensures direct contact with current and
potential customers; and

. monitors the changing requirements of our customers.

As of June 30, 1999, Extreme's worldwide sales and marketing organization
included 116 individuals, including managers, sales representatives, and
technical and administrative support personnel. We have domestic sales offices
located in major metropolitan areas, including Atlanta, Boston, Chicago,
Dallas, Houston, Los Angeles, New York, San Jose, Seattle and Washington DC. In
addition, we have international sales offices located in France, Germany, Hong
Kong, Italy, Japan, The Netherlands, Sweden and United Kingdom.

International sales

We believe that there is a strong international market for our switching
products. Our international sales are conducted primarily through our overseas
offices and foreign resellers. Sales to customers outside of North America
accounted for approximately 53% of our net revenue in fiscal 1999.

Marketing

We have a number of marketing programs to support the sale and distribution
of our products and to inform existing and potential enterprise customers and
our resellers and OEMs about the capabilities and benefits 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, maintenance of our web site, advertising and public relations. In
addition, we have begun to develop an e-commerce business directed at
resellers. We also participate in third-party, independent product tests.

Customer Support and Service

Our customer service and support organization maintains and supports
products sold by our field sales force to end users, and provides technical
support to our resellers and OEMs. Generally, our resellers and OEMs provide
installation, maintenance and support services to their customers and we assist
our resellers and OEMs in providing such support.

In addition to designing custom maintenance programs to satisfy specific
customer requirements, we also offer several standard maintenance programs to
our resellers and customers, including ExtremeAssist1 and ExtremeAssist2.

ExtremeAssist1. This program is designed for customers which have strong
technical networking skills and are interested in keeping service and support
costs to a minimum. With ExtremeAssist1, the customers' information technology
organizations provide first-level support for configuration, hardware and
trouble shooting, while our technical assistance center provides advanced
second-level support on an essential need basis. The ExtremeAssist1 program
includes 2 hour telephone response time, 10 e-mail inquiries per month and
responses within 24 hours, rapid-response emergency telephone support 24 hours
a day, seven days a week and 72-hour advanced replacement of hardware.


11


ExtremeAssist2. This program is designed for mission-critical environments
that require the highest degree of network availability, data integrity and
end-user productivity. The ExtremeAssist2 program includes 1 hour telephone
response time, unlimited e-mail inquiries and next business-day responses,
rapid-response emergency/ network down telephone support 24 hours a day, seven
days a week and next business-day advance replacement of hardware.

With the ExtremeAssist1 and ExtremeAssist2 programs, our customers are able
to access our web-based database to immediately obtain software updates, bug
lists, technical support alerts and on-line documentation. We typically provide
end users with a one-year hardware and 90-day software warranty. We also offer
various training courses for their third-party resellers or end-user customers.

Manufacturing

We outsource the majority of our manufacturing and supply chain management
operations, and we conduct quality assurance, manufacturing engineering,
documentation control and repairs at our facility in Santa Clara, California.
This approach enables us to reduce fixed costs and to provide flexibility in
meeting market demand. Where cost-effective, we may begin to perform certain of
our non-manufacturing outsourced operations in-house.

Currently, we use two contract manufacturers--Flextronics, located in San
Jose, California, to manufacture our Summit1, Summit2 and Summit4 and
BlackDiamond products and MCMS, located in Boise, Idaho, to manufacture our
Summit24 and Summit48 products. Each of these manufacturing processes and
procedures is ISO 9002 certified. We design and develop the key components of
our products, including ASICs, printed circuit boards and software. In
addition, we determine the components that are incorporated in our products and
select the appropriate suppliers of such components. Product testing and burn-
in is performed by our contract manufacturers using tests we specify and
automated testing equipment. We also use 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, which will require that we rapidly achieve volume production by
coordinating our efforts with those of our suppliers and contract
manufacturers. See "Factors That May Affect Our Results--Extreme Needs to
Expand Its Manufacturing Operations and Depends on Contract Manufacturers for
Substantially All of Its Manufacturing Requirements."

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

. ASICs;

. microprocessors;

. programmable integrated circuits;

. selected other integrated circuits;

. cables; and

. custom-tooled sheet metal.

Our principal limited-source components include:

. flash memories;

. DRAMs;

. SRAMs; and

. printed circuit boards.


12


Generally, purchase commitments with our single or limited source suppliers
are on a purchase order basis. LSI Logic manufacturers all of our ASICs which
are used in all of our switches. 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, would
materially adversely affect our business, operating results and financial
condition. In addition, qualifying additional suppliers can be time-consuming
and expensive and may increase the likelihood of errors.

We use a rolling six-month forecast based on anticipated product orders 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. See "Factors That
May Affect Our Results--Extreme Purchases Several Key Components for Products
From Single or Limited Sources and Could Lose Sales if These Sources Fail to
Fill Its Needs" and "--Extreme Needs To Expand Its Manufacturing Operations and
Depends on Contract Manufacturers for Substantially All of Its Manufacturing
Requirements."

Research and Development

We believe that our future success depends on our ability to continue to
enhance our existing products and to develop new products that maintain
technological competitiveness. We focus our product development activities on
solving the needs of enterprise LANs, ISPs and content providers. We monitor
changing customer needs and work closely with users, value-added resellers and
distributors, and market research organizations to monitor changes in the
marketplace. We design our products around current industry standards and will
continue to support emerging standards that are consistent with our product
strategy.

Our products have been designed to incorporate the same core ASICs and
software and system architecture, facilitating a relatively short product
design and development cycle and reducing the time to market for new products
and features. We have utilized this architectural design to develop and
introduce other product models and enhancements since the introduction of our
first products in 1997. We intend to continue to utilize this architectural
design to develop and introduce additional products and enhancements in the
future.

We are undertaking development efforts for our family of products with
emphasis on increasing reliability, performance and scalability and reducing
the overall network operating costs to end users. We are developing a new
chipset which will be compatible with our existing architecture. We expect to
ship new products that incorporate the new chipset in this fiscal year. We are
also focusing on cost reduction engineering to reduce the cost of our products.
There can be no assurance that our product development efforts will result in
commercially successful products, or that our products will not be rendered
obsolete by changing technology or new product announcements by other
companies. See "Factors That May Affect Our Results--Extreme's Market is
Subject to Rapid Technological Change and to Compete, Extreme Must Continually
Introduce New Products that Achieve Broad Market Acceptance."

Competition

The market for network switches is part of the broader market for enterprise
LAN equipment, which is dominated by a few large companies, particularly
Cabletron Systems, Cisco Systems, Nortel and 3Com. Each of these companies has
introduced, or has announced its intention to develop, switches that are or may
be competitive with our products. For example, in January 1999, Cisco announced
its Catalyst 6000 family of chassis-based switches. In addition, there are a
number of large telecommunications equipment providers, including Alcatel,
Ericsson, Lucent Technologies, Nokia, Nortel Networks and Siemens, which have
entered the market for network equipment, particularly through acquisitions of
public and privately held companies. For example, in January 1998, Lucent
acquired Prominet, a private switching company. We expect to face increased
competition, particularly price competition, from these and other
telecommunications equipment providers. We also expect to compete with other
public and private companies that offer switching solutions, such as Alteon Web
Systems and Foundry Networks. These vendors may develop products with
functionality

13


similar to our products or provide alternative network solutions. Our OEMs may
compete with us with their current products or products they may develop, and
with the products they purchase from us. 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
LAN or in ISP 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 extremely
confident in and committed to the product offerings of our principal
competitors, including Cisco Systems, Nortel Networks and 3Com. Accordingly,
such 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 such
sales.

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

. expertise and familiarity with network protocols, network switching and
network management;

. product performance, features, functionality and reliability;

. price/performance characteristics;

. timeliness of new product introductions;

. adoption of emerging industry standards;

. customer service and support;

. size and scope of distribution network;

. brand name;

. access to customers; and

. size of installed customer base.

We believe 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 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 which will materially
adversely affect our business. See "Factors That May Affect Our Results--
Intense Competition in the Market for Networking Equipment Could Prevent
Extreme From Increasing Revenue and Prevent Extreme From Achieving or
Sustaining Profitability."

Intellectual Property

We rely on a combination of patent, copyright, trademark and trade secret
laws and restrictions on disclosure to protect our intellectual property
rights. We have been issued one patent in the U.S. We have filed twelve patent
applications in the U.S. and selected countries abroad relating to the
architecture of our network switches and quality of service features. There can
be no assurance that these applications will be approved,

14


that any issued patents will protect our intellectual property or that they
will not be challenged by third parties. Furthermore, there can be no assurance
that others will not independently develop similar or competing technology or
design around any patents that may be issued. We also have six pending
trademark applications in the U.S.

We also 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-users 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 exclusive
patent, copyright, trademark and other intellectual property rights to
technologies and related standards that are important to us. We expect that we
may increasingly be subject to infringement claims as the numbers of products
and competitors in the market for network switches grow and the functionality
of products overlaps. In this regard, in February 1999, we received verbal
communications from one of our OEM customers that one of these companies
believes that our products may infringe patents pertaining to a Gigabit
Ethernet industry standard, which standard was developed by committees and
includes contributions from numerous parties. As such, it is not currently
known whether a license is necessary; however, if it is determined to be
necessary, we believe that a license would be made available in a timely and
non-discriminatory manner and on reasonable terms.

Although we have not been a party to any litigation asserting claims that
allege infringement of intellectual property rights, we cannot assure you that
we will not be a party to litigation in the future. In addition, we cannot
assure you that third parties will not assert additional claims or initiate
litigation against us or our manufacturers, suppliers or customers alleging
infringement of their proprietary rights with respect to existing or future
products.

We may in the future initiate claims or litigation against third parties for
infringement of our proprietary rights to determine the scope and validity of
our proprietary rights. Any such claims, with or without merit, 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. Such royalty or licensing
agreements, if required, may not be available on acceptable terms, if at all.
In the event of a successful claim of infringement and our failure or inability
to develop non-infringing technology or license the proprietary rights on a
timely basis, our business, operating results and financial condition could be
materially adversely affected.

Employees

As of June 30, 1999, we employed 249 persons, including 116 in sales and
marketing, 62 in research and development, 33 in operations and 38 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 will depend 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

15


personnel. None of our personnel is bound by an employment agreement.
Competition for qualified personnel is intense, particularly in the San
Francisco Bay Area, where our headquarters is located. At times we have
experienced difficulties in attracting new personnel. There can be no assurance
that we will successfully attract, integrate, retain and motivate a sufficient
number of qualified personnel to conduct our business in the future. See
"Factors That May Affect Our Results--If Extreme Loses Key Personnel or is
Unable to Hire Additional Qualified Personnel as Necessary, It May Not Be Able
to Successfully Manage Its Business or Achieve Its Objectives."

Item 2. Properties.

Our principal administrative, sales, marketing and research development
facilities are located in an approximately 77,000 square feet facility located
in Santa Clara, California which we moved to in March 1999. The Company
believes that suitable additional space will be available as needed to
accommodate any further physical expansion of corporate operations and for any
additional sales offices. We also lease office space in Connecticut, Florida,
Georgia, Illinois, Massachusetts, New Jersey, Texas, Washington, Washington
D.C. and Wisconsin and in Germany, Hong Kong, The Netherlands and United
Kingdom.

Item 3. Legal Proceedings.

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.

Item 4. Submission of Matters to a Vote of Security Holders.

Not applicable.

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

When used in this discussion and elsewhere in this Form 10-K, the words
"may," "should," "believes," "expects," "anticipates," "estimates" and similar
expressions are intended to identify forward-looking statements. Such
statements, which include statements concerning the availability and
functionality of products under development, product mix, pricing trends, the
mix of export sales, sales to significant customers and the availability and
cost of products from the Company's suppliers, are subject to risks and
uncertainties, including those set forth below under "Factors That May Affect
Our Results." Our actual results could differ materially from those projected
in these forward-looking statements which could have a material adverse effect
on our business, operating results and financial condition. These forward-
looking statements speak only as of the date hereof and there may be events in
the future that we are not able to predict accurately or over which we have no
control.

Overview

From our inception in May 1996 through September 1997, our operating
activities related primarily to developing a research and development
organization, testing prototype designs, building an ASIC design
infrastructure, commencing the staffing of our marketing, sales and field
service and technical support organizations, and establishing relationships
with resellers and OEMs. We commenced volume shipments of our Summit1 and
Summit2, the initial products in our Summit stackable product family, in
October 1997, and we began shipping our BlackDiamond modular product family in
September 1998. Since inception, we have incurred significant losses and as of
June 30, 1999, we had an accumulated deficit of $23.5 million.

Our revenue is derived primarily from sales of our Summit and BlackDiamond
product families and fees for services relating to our products, including
maintenance and training. 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. See "Factors That May Affect Our
Results--If a Key Reseller, OEM or Other Significant Customer Cancels or Delays
a Large Purchase, Extreme's Revenues May Decline and the Price of Its Stock May
Fall." Significant customer concentration in fiscal 1999 and fiscal 1998 as a
percentage of net revenue is summarized below:



Year Ended
June 30,
----------
1999 1998
---- ----

Customer
3Com............................ -- 25%
Compaq.......................... 21% 21%
Hitachi Cable................... 13% --


We market and sell our products primarily through resellers and, to a lesser
extent, OEMs and our field sales organization. We sell our products through
more than 130 resellers in 40 countries. In fiscal 1999, sales to customers
outside of North America accounted for approximately 53% of our net revenue.
Currently, all of our international sales are denominated in U.S. dollars. We
generally recognize product revenue at the time of shipment, unless we have
future obligations for installation or have to obtain customer acceptance, in
which case revenue is deferred until such obligations have been satisfied. We
have established a program which, under specified conditions, enables third
party resellers to return products to us. The amount of potential product
returns is estimated and provided for in the period of the sale. Service
revenue is recognized ratably over the term of the contract period, which is
typically 12 months.

We expect to experience rapid 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 gross margins will be
affected by such declines and by fluctuations in manufacturing volumes,
component costs and the mix of product configurations sold. In addition, our
gross margins may fluctuate due to the mix of

19


distribution channels through which our products are sold, including the
potential effects of our development of a two-tier distribution channel. We
generally realize higher gross margins on sales to resellers than on sales
through our OEMs. Any significant decline in sales to our OEMs or resellers, or
the loss of any of our OEMs or resellers, could materially adversely affect our
business, operating results and financial condition. In addition, new product
introduction may result in excess or obsolete inventories. Any excess or
obsolete inventories may also reduce our gross margins.

We outsource the majority of our manufacturing and supply chain management
operations, and we conduct quality assurance, manufacturing engineering,
documentation 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 and MCMS. We expect to realize lower
per unit product costs as a result of volume efficiencies. However, we cannot
assure you when or if such price reductions will occur. The failure to obtain
such price reductions could materially adversely affect our gross margins and
operating results.

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 ASICs and software. We
expense all research and development expenses as incurred. We believe that
continued investment in research and development is critical to attaining our
strategic objectives and, as a result, we expect these expenses to increase in
absolute dollars in the future.

Selling and marketing expenses consist of salaries, commissions and related
expenses for personnel engaged in marketing, sales and field service support
functions, as well as trade shows and promotional expenses. We intend to pursue
selling and marketing campaigns aggressively and therefore expect these
expenses to increase significantly in absolute dollars in the future. In
addition, we expect to substantially expand our field sales operations to
support and develop leads for our resellers, which would also result in an
increase in selling and marketing expenses.

General and administrative expenses consist primarily of salaries and
related expenses for executive, finance and administrative personnel,
recruiting expenses, professional fees and other general corporate expenses. We
expect general and administrative expenses to increase in absolute dollars as
we add personnel, increase spending on our information systems and incur
additional costs related to the growth of our business and operation as a
public company.

During fiscal 1998, in connection with the grant of certain stock options to
employees, we recorded deferred stock compensation of $437,000 representing the
difference between the exercise price and the deemed fair value of our common
stock on the date such stock options were granted. Such amount is included as a
reduction of stockholders' equity and is being amortized by charges to
operations on a graded vesting method. We recorded amortization of deferred
stock compensation expense of approximately $172,000 and $68,000 for fiscal
1999 and fiscal 1998, respectively. At June 30, 1999, we had a total of
approximately $197,000 remaining to be amortized over the corresponding vesting
period of each respective option, generally four years. The amortization
expense relates to options awarded to employees in all operating expense
categories.

Despite growing revenues, we have only been profitable for the quarters
ended June 30, 1999 and March 31, 1999. Our net losses have not decreased
proportionately with the increase in our revenue primarily because of increased
expenses relating to our growth in operations. Because of the lengthy sales
cycle of our products, there is often a significant delay between the time we
incur expenses and the time we realize the related revenue. See "Factors That
May Affect Our Results--The Sales Cycle for Extreme's Products is Long and
Extreme May Incur Substantial Non-Recoverable Expenses or Devote Significant
Resources to Sales that Do Not Occur When Anticipated." To the extent that
future revenues do not increase significantly in the same periods in which
operating expenses increase, our operating results would be adversely affected.
See "Factors That May Affect Our Results--A Number of Factors Could Cause
Extreme's Quarterly Financial Results to Be Worse Than Expected, Resulting in a
Decline in Its Stock Price."

Net Revenue

Net revenue increased from $23.6 million in fiscal 1998 to $98.0 million in
fiscal 1999, an increase of $74.4 million. The increase in net revenue for
fiscal 1999 resulted primarily from increased sales of our Summit stackable
products and the introduction of our BlackDiamond modular product family in
September 1998.

Net revenue increased from $256,000 in fiscal 1997 to $23.6 million in
fiscal 1998, an increase of $23.3 million. The increase in net revenue for
fiscal 1998 reflected the commencement of shipments by our OEMs in the quarter
ending September 30, 1997 and the introduction of our Summit stackable product
family in the quarter ending December 31, 1997. Net revenue for fiscal 1997
was negligible as we were in the start-up stage of development.

Export sales accounted for 53% and 61% of net revenue in fiscal 1999 and
fiscal 1998, respectively. The overall increase in export sales reflected the
growth in demand for our Summit and BlackDiamond products and an increase in
the number of resellers, offset in part by a decrease in OEM sales. We expect
that export sales will continue to represent a significant portion of net
revenue, although we cannot assure you that export sales as a percentage of
net revenue will remain at current levels. All sales transactions are
denominated in U.S. dollars.

Gross Profit

Gross profit increased from $8.7 million in fiscal 1998 to $49.5 million in
fiscal 1999, an increase of $40.8 million. Gross margins increased from 36.8%
in fiscal 1998 to 50.5% in fiscal 1999. The increase in gross margin resulted
primarily from reductions in component costs, improved manufacturing
efficiencies and a shift in our channel mix from OEMs to resellers, which were
offset in part by lower average selling prices due to increased competition.

Gross profit increased from a loss of ($132,000) in fiscal 1997 to a profit
of $8.7 million in fiscal 1998, an increase of $8.8 million. Gross margins
increased from (51.6%) in fiscal 1997 to 36.8% in fiscal 1998. The increase
resulted from a shift from primarily research and development activities to
production and sales of our products.

21


Research and Development Expenses

Research and development expenses increased from $10.7 million in fiscal
1998 to $17.0 million in fiscal 1999, an increase of $6.3 million. The increase
was primarily due to nonrecurring engineering and initial product verification
expenses, the hiring of additional engineers and an increase in depreciation
charges due to increases in capital spending on design and simulation software
and test equipment. For fiscal 1998 and fiscal 1999, research and development
expenses decreased as a percentage of net revenue from 45.2% to 17.4%. This
percentage decrease was primarily the result of an increase in our net revenue.

Research and development expenses increased from $5.4 million in fiscal 1997
to $10.7 million in fiscal 1998, an increase of $5.3 million. The increase
resulted primarily from the hiring of additional engineers and an increase in
prototype material expenses for new product development. For fiscal 1997 and
fiscal 1998, research and development expenses decreased as a percentage of net
revenue from 2090.2% to 45.2%. This percentage decrease was primarily the
result of an increase in our net revenue.

Selling and Marketing Expenses

Selling and marketing expenses increased from $9.6 million in fiscal 1998 to
$27.1 million in fiscal 1999, an increase of $17.5 million. This increase was
primarily due to the hiring of additional sales and customer support personnel,
tradeshow and promotional expenses, increased commission expenses resulting
from higher sales, and the establishment of new sales offices. For fiscal 1998
and fiscal 1999, selling and marketing expenses decreased as a percentage of
net revenue from 40.7% to 27.6%. This percentage decrease was primarily the
result of an increase in our net revenue.

Selling and marketing expenses increased from $1.6 million in fiscal 1997 to
$9.6 million in fiscal 1998, an increase of $8.0 million. This increase was
primarily due to the hiring of additional sales and customer support personnel,
advertising and promotional campaigns in support of the introduction of our
Summit stackable product family. For fiscal 1997 and fiscal 1998, selling and
marketing expenses decreased as a percentage of net revenue from 607.0% to
40.7%. This percentage decrease was primarily the result of an increase in our
net revenue.

General and Administrative Expenses

General and administrative expenses increased from $2.4 million in fiscal
1998 to $6.9 million in fiscal 1999, an increase of $4.5 million. This increase
was due primarily to the hiring of additional finance, information technology
and legal and administrative personnel, recruiting expenses, professional fees
and increased spending on information systems. For fiscal 1998 and fiscal 1999,
general and administrative expenses decreased as a percentage of net revenue
from 10.4% to 7.0%. This percentage decrease was primarily the result of an
increase in our net revenue.

General and administrative expenses increased from $1.0 million in fiscal
1997 to $2.4 million in fiscal 1998, an increase of $1.4 million. This increase
reflected primarily additional finance, information technology and legal and
administrative personnel, recruiting expenses, professional fees and increased
spending on our information systems. For fiscal 1997 and fiscal 1998, general
and administrative expenses decreased as a percentage of net revenue from
399.6% to 10.4%. This percentage decrease was primarily the result of an
increase in our net revenue.

Interest Income

Interest income increased from $.6 million in fiscal 1998 to $1.9 million in
fiscal 1999, an increase of $1.3 million. The increase is due to the increased
amount of cash and cash equivalents, short-term investments and long-term
investments from the proceeds we received from our initial public offering in
April 1999.

22


Income Taxes

We incurred significant operating losses for all fiscal years from inception
through June 30, 1999. We recorded a tax provision of $1,650,000 for the year
ended June 30, 1999. The provision for income taxes consists primarily of
foreign taxes, federal alternative minimum taxes and state income taxes. FASB
Statement No. 109 provides for the recognition of deferred tax assets if
realization of such assets is more likely than not. Based upon the weight of
available evidence, which includes our historical operating performance and the
reported cumulative net losses in all prior years, we have provided a full
valuation allowance against our net deferred tax assets as the future
realization of the tax benefit is not sufficiently assured. We intend to
evaluate the realizability of the deferred tax assets on a quarterly basis.

Liquidity and Capital Resources

Cash and cash equivalents and short-term investments increased from $20.5
million at June 30, 1998 to $123.6 million at June 30, 1999, an increase of
$103.1 million. The increase is primarily a result of our initial public
offering of common stock in April 1999, which generated net proceeds of $125.3
million. Cash provided by operating activities was $2.8 million in fiscal 1999,
as compared to cash used for operating activities of $8.3 million in fiscal
1998. The decrease was primarily due to increases in accounts receivable,
inventories and other current and noncurrent assets, offset by our operating
loss, depreciation and increases in accounts payable and accrued liabilities.
We expect that accounts receivable will continue to increase to the extent our
revenues continue to rise. We expect our inventory levels to increase in
connection with our development of a two-tier distribution system. Any such
increase can be expected to reduce cash, cash equivalents and short-term
investments.

Investing activities used cash of $29.1 million in fiscal 1999 due to
capital expenditures of $7.5 million and net purchases of short-term
investments of $21.6 million. Our investing activities used cash of
$13.5 million in fiscal 1998 for purchases of short-term investments of $11.0
million and capital expenditures of $2.5 million. Our investing activities used
cash of $1.2 million in fiscal 1997 for capital expenditures. We expect capital
expenditures of approximately $20.0 million in fiscal 2000.

Financing activities provided cash of $124.0 million in fiscal 1999, arising
primarily from proceeds from the issuance of common stock in conjunction with
our initial public offering, partially offset by principal payments on notes
payable and capital lease obligations. Financing activities provided cash of
$21.2 million in fiscal 1998, primarily from the issuance of convertible
preferred stock and proceeds from notes payable, partially offset by principal
payments on notes payable and capital lease obligations. Financing activities
provided cash of $17.8 million in fiscal 1997, primarily from the issuance of
convertible preferred stock and proceeds from notes payable.

We have a revolving line of credit for $5.0 million with Silicon Valley
Bank. Borrowings under this line of credit bear interest at the bank's prime
rate. As of June 30, 1999, there were no outstanding borrowings under this line
of credit. We also have a capital equipment line with Silicon Valley Bank for
$4.0 million. Borrowings under this capital equipment line bear interest at the
bank's prime rate. This agreement requires that we maintain certain financial
ratios and levels of tangible net worth, profitability and liquidity. We were
in compliance with the financial statement covenants as of June 30, 1999. As of
June 30, 1999, there were no outstanding borrowings under this capital
equipment line. In addition, we have a $2.0 million capital equipment line with
Comdisco, Inc. As of June 30, 1999, there were no outstanding borrowings under
this capital equipment line.

In February 1999, we agreed to lease a 77,000 square foot facility in Santa
Clara, California. The related cost of this lease is expected to be
approximately $120,000 per month. The lease has a term of 47 months.

We require substantial capital to fund our business, particularly to finance
inventories and accounts receivable and for capital expenditures. In order to
build a sustainable business, the trend of using cash in our

23


operations is expected to continue over the next several quarters. We are
working toward a business model that will allow us to consistently generate
cash from operations. Achieving this model will depend on many factors,
including the rate of revenue growth, the timing and extent of spending to
support product development efforts and expansion of sales and marketing, the
timing of introductions of new products and enhancements to existing products,
and market acceptance of our products. As a result, we could be required to
raise substantial 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 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 term of such debt could impose restrictions on our
operations. We cannot assure you that such additional capital, if required,
will be available on acceptable terms, or at all. 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 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.

Year 2000 Readiness Disclosure

Some computers, software and other equipment include computer code in which
calendar year data is abbreviated to only two digits. As a result of this
design decision, some of these systems could fail to operate or fail to produce
correct results if "00" is interpreted to mean 1900, rather than 2000. These
problems are widely expected to increase in frequency and severity as the year
2000 approaches, and are commonly referred to as the "year 2000 problem."

Assessment. The year 2000 problem affects the computers, software and other
equipment that we use, operate or maintain for our operations. Accordingly, we
have organized a program team responsible for monitoring the assessment and
remediation status of our year 2000 projects and reporting such status to our
board of directors. This program team has assessed the potential effect and
costs of remediating the year 2000 problem for our internal systems. To date,
we have not obtained verification or validation from any independent third
parties of our processes to assess and correct any of our year 2000 problems or
the costs associated with these activities.

Internal infrastructure. We have identified and evaluated approximately 250
personal computers and servers, six software applications, including Microsoft
Windows 95, Microsoft Office 97 and Outlook 98 and Microsoft Mail Server, and
our enterprise resource planning system, and related equipment used in
connection with our internal operations to determine if they must be modified,
upgraded or replaced to minimize the possibility of a material disruption to
our business. We have commenced the process of modifying, upgrading, and
replacing major systems that have been assessed as adversely affected, and
expect to complete this process before the occurrence of any material
disruption of our business.

Systems other than information technology systems. In addition to computers
and related systems, the operation of office and facilities equipment, such as
fax machines, telephone switches, security systems, and other common devices
may be affected by the year 2000 problem. To date, we have been able to correct
any problems with our systems other than information technology systems
relating to year 2000. We currently do not expect any significant problems to
arise with our systems other than information technology systems relating to
the year 2000.

Products and software programs. We have tested and intend to continue to
test all of our products and software programs for year 2000 problems. To date,
we have been able to correct any problems with our products and software
programs relating to year 2000 prior to releasing them to our customers. We
currently do not expect any significant problems to arise with our products and
software programs relating to the year 2000.

24


We estimate the total cost to us of completing any required modifications,
upgrades or replacements of our internal systems will not exceed $200,000,
almost all of which we believe will be incurred during calendar 1999. This
estimate is being monitored and we will revise it as additional information
becomes available.

Based on the activities described above, we do not believe that the year
2000 problem will have a material adverse effect on our business or operating
results. In addition, we have not deferred any material information technology
projects as a result of our year 2000 problem activities.

Suppliers. We are checking the web sites of third-party suppliers of
components used in the manufacture of our products to determine if these
suppliers are certifying that the components they provide us are year 2000
compliant. To date, we believe all critical components that we obtain from
third party suppliers are year 2000 compliant, except that Microsoft has not
indicated that Windows 95 and its office mail programs are year 2000 compliant.
We expect that we will be able to resolve any significant year 2000 problems
with Microsoft and any other third-party suppliers of components; however,
there can be no assurance that these suppliers will resolve any or all year
2000 problems before the occurrence of a material disruption to the operation
of our business. Any failure of these third parties to timely resolve year 2000
problems with their systems could have a material adverse effect on our
business, operating results and financial condition.

Most likely consequences of year 2000 problems. We expect to identify and
resolve all year 2000 problems that could materially adversely affect our
business operations. However, we believe that it is not possible to determine
with complete certainty that all year 2000 problems affecting us have been
identified or corrected. The number of devices that could be affected and the
interactions among these devices are simply too numerous. In addition, no one
can accurately predict how many year 2000 problem-related failures will occur
or the severity, duration, or financial consequences of these perhaps
inevitable failures. As a result, we believe that the following consequences
are possible:

. a significant number of operational inconveniences and inefficiencies for
us, our contract manufacturers and our customers that will divert
management's time and attention and financial and human resources from
ordinary business activities;

. several business disputes and claims for pricing adjustments or penalties
due to year 2000 problems by our customers, which we believe will be
resolved in the ordinary course of business; and

. a few serious business disputes alleging that we failed to comply with
the terms of contracts or industry standards of performance, some of
which could result in litigation or contract termination.

Contingency plans. We have developed contingency plans to be implemented if
our efforts to identify and correct year 2000 problems affecting our internal
systems are not effective. Depending on the systems affected, these plans could
include:

. accelerated replacement of affected equipment or software;

. short to medium-term use of backup equipment and software;

. increased work hours for our personnel; and

. use of contract personnel to correct on an accelerated schedule any year
2000 problems that arise or to provide manual workarounds for information
systems.

Our implementation of any of these contingency plans could have a material
adverse effect on our business, operating results and financial condition.

Disclaimer. The discussion of our efforts and expectations relating to year
2000 compliance are forward-looking statements. Our ability to achieve year
2000 compliance and the level of incremental costs associated therewith, could
be adversely affected by, among other things, the availability and cost of
programming and testing resources, third party suppliers' ability to modify
proprietary software, and unanticipated problems identified in the ongoing
compliance review.

25


Factors That May Affect Our Results

Extreme Has a General History of Losses, and Limited History of Profitability
and Cannot Assure You that it Will Continue to Achieve Profitability

We have not achieved profitability on an annual basis and although our
revenue has grown in recent quarters, we cannot be certain that we will realize
sufficient revenue to achieve profitability on an annual basis. Extreme has
incurred net losses of $7.9 million from inception through June 30, 1997, $13.9
million for fiscal 1998 and $1.6 million for fiscal 1999. As of June 30, 1999,
we had an accumulated deficit of $23.5 million. We anticipate continuing to
incur significant sales and marketing, product development and general and
administrative expenses and, as a result, we will need to generate
significantly higher revenue to sustain profitability. Although our revenues
have grown in recent quarters and we have recently achieved quarterly
profitability, we cannot be certain that we will continue to realize sufficient
revenue to sustain profitability.

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

We plan to significantly increase our operating expenses to expand our sales
and marketing activities, broaden our customer support capabilities, develop
new distribution channels, fund increased levels of research and development
and build our operational infrastructure. We base our operating expenses on
anticipated revenue trends and a high percentage of our expenses are fixed in
the short term. As a result, any delay in generating or recognizing revenue
could cause our quarterly operating results to be below the expectations of
public market analysts or investors, which could cause the price of our common
stock to fall.

We may experience a delay in generating or recognizing revenue because of a
number of reasons. Orders at the beginning of each quarter typically do not
equal expected revenue for that quarter and are generally cancelable at any
time. Accordingly, we are dependent upon obtaining orders in a quarter for
shipment in that quarter to achieve our revenue objectives. In addition, the
timing of product releases, purchase orders and product availability could
result in significant product shipments at the end of a quarter. Failure to
ship these products by the end of a quarter may adversely affect our operating
results. Furthermore, our customer agreements typically provide that the
customer may delay scheduled delivery dates and cancel orders within specified
time frames without significant penalty.

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:

. fluctuations in demand for our products and services, including
seasonality, particularly in Asia and Europe;

. unexpected product returns or the cancellation or rescheduling of
significant orders;

. our ability to develop, introduce, ship and support new products and
product enhancements and manage product transitions;

. announcements and new product introductions by our competitors;

. our ability to develop and support customer relationships with ISPs and
other potential large customers;

. our ability to achieve required cost reductions;

. our ability to obtain sufficient supplies of sole or limited sourced
components for our products;

. unfavorable changes in the prices of the components we purchase;

. our ability to attain and maintain production volumes and quality levels
for our products;

. the mix of products sold and the mix of distribution channels through
which they are sold; and

. costs relating to possible acquisitions and integration of technologies
or businesses.

26


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
Extreme From Increasing Revenue and Prevent Extreme From Sustaining
Profitability

The market for network switches is intensely competitive. Our principal
competitors include Alcatel, Cabletron Systems, Cisco Systems, Ericsson,
Foundry Networks, Lucent Technologies, Nokia, Nortel Networks, Siemens and
3Com. 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 larger installed
customer bases, than we do. These competitors may have developed or could in
the future develop new technologies that compete with our products or even
render our products obsolete.

To remain competitive, we believe we must, among other things, invest
significant resources in developing new products and enhancing our current
products and maintaining customer satisfaction. If we fail to do so, our
products may not compete favorably with those of our competitors and our
revenue and future profitability could be materially adversely affected.

Extreme Expects the Average Selling Prices of Its Products to Decrease Rapidly
Which May Reduce Gross Margins or Revenue

The network equipment industry has experienced rapid erosion of average
selling prices due to a number of factors, including competitive pricing
pressures and rapid technological change. We may experience substantial period-
to-period fluctuations in future operating results due to the erosion of our
average selling prices. We anticipate that the average selling prices of our
products will decrease in the future in response to competitive pricing
pressures, increased sales discounts, new product introductions by us or our
competitors, including, for example, competitive products manufactured with low
cost merchant silicon, or other factors. Therefore, to maintain our gross
margins, 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 cause our revenue and gross margins to decline, which could
materially adversely affect our operating results and cause the price of our
common stock to decline.

Extreme's Market is Subject to Rapid Technological Change and to Compete,
Extreme Must Continually Introduce New Products that Achieve Broad Market
Acceptance

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

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 purchasing our existing products. These actions could
materially adversely affect our operating results by unexpectedly decreasing
sales, increasing our 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

27


or are compatible with these new technologies as they emerge. We have
experienced delays in releasing new products and product enhancements in the
past which delayed sales and resulted in lower quarterly revenue than
anticipated. We may experience similar delays in product development in the
future and any delay in product introduction could adversely affect our ability
to compete and cause our operating results to be below our expectations or the
expectations of public market analysts or investors.

Continued Rapid Growth Will Strain Extreme's Operations and Will Require
Extreme to Incur Costs to Upgrade Its Infrastructure

Since the introduction of our product line, we have experienced a period of
rapid growth and expansion which has placed, and continues to place, a
significant strain on our resources. Unless we manage such growth effectively,
we may make mistakes in operating our business such as inaccurate sales
forecasting, incorrect material planning or inaccurate financial reporting,
which may result in unanticipated fluctuations in our operating results. Our
net revenue increased significantly during the last year, and from June 30,
1998 to June 30, 1999, the number of our employees increased from 119 to 249.
We expect our anticipated growth and expansion to strain our management,
operational and financial resources. Our management team has had limited
experience managing such rapidly growing companies on a public or private
basis. To accommodate this anticipated growth, we will be required to:

. improve existing and implement new operational, information and financial
systems, procedures and controls;

. hire, train and manage additional qualified personnel, including in the
near future sales and marketing personnel; and

. effectively manage multiple relationships with our customers, suppliers
and other third parties.

We may not be able to install adequate control systems in an efficient and
timely manner, and our current or planned personnel systems, procedures and
controls may not be adequate to support our future operations. For example, in
the quarter ended June 30, 1998, our operating results were adversely impacted
due to a provision of approximately $900,000 that we recorded for purchase
order commitments for certain components that exceeded our estimated
requirements at the end of that quarter. This was due primarily to an
engineering change in certain of our Summit family of products and a reduced
demand forecast from one of our customers. In August 1998, we installed a new
management information system, which we may continue to modify and improve to
meet the increasing needs associated with our expected growth. The difficulties
associated with installing 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 have 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.

Extreme Must Develop and Expand Its Indirect Distribution Channels to Increase
Revenues and Improve Its Operating Results

Our distribution strategy focuses primarily on developing and expanding
indirect distribution channels through resellers and, to a lesser extent,
original equipment manufacturers, or OEMs, as well as expanding our field sales
organization. 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 would
suffer. Many of our resellers also sell products that compete with our
products. We are developing a two-tier distribution structure in Europe and the
United States which has and will require us to enter into agreements with a
small number of stocking distributors. We cannot assure you that we will
continue to be able to enter into such agreements or that we will be able to
successfully manage our resellers and distributors. Our failure to do so 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

28


that our resellers will market our products effectively or continue to devote
the resources necessary to provide us with effective sales, marketing and
technical support.

In order to support and develop leads for our indirect distribution
channels, we plan to expand our field sales and support staff significantly. We
cannot assure you that this internal expansion will be successfully completed,
that the cost of this expansion will not exceed the revenues generated or that
our expanded sales and support staff will be able to compete successfully
against the significantly more extensive and well-funded sales and marketing
operations of many of our current or potential competitors. Our inability to
effectively establish our distribution channels or manage the expansion of our
sales and support staff would materially adversely affect our ability to grow
and increase revenue.

Because Substantially All of Extreme's Revenue is Derived From Sales of Two
Product Families, Extreme is Dependent on Widespread Market Acceptance of These
Products; Future Performance will Depend on the Introduction and Acceptance of
New Products

We currently derive substantially all of our revenue from sales of our
Summit and BlackDiamond product families. 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 critical to our future success. Factors that may affect the market
acceptance of our products include market acceptance of switching products, and
Gigabit Ethernet and Layer 3 switching technologies in particular in the
enterprise LAN, ISP and content provider markets, the performance, price and
total cost of ownership of our products, the availability and price of
competing products and technologies, and the success and development of our
resellers, OEMs and field sales channels. Many of these factors are beyond our
control. 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 cost-effective manner. We are developing products
which we expect to introduce this fiscal year which are based on a new chip set
under development. The introduction of new and enhanced products may cause our
customers to defer or cancel orders for existing products. We have in the past
experienced delays in product development and such delays may occur in the
future. Therefore, to the extent customers defer or cancel orders in the
expectation of any new product release, any delay in development or
introduction could cause our operating results to suffer. Failure of our
existing or future products to maintain and achieve widespread levels of market
acceptance may significantly impair our revenue growth.

If a Key Reseller, OEM or Other Significant Customer Cancels or Delays a Large
Purchase, Extreme's Revenues May Decline and the Price of Its Stock May Fall

To date, a limited number of resellers, OEMs 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 fiscal 1998, 3Com and Compaq accounted for 25% and 21%
of our net revenue, respectively, and for fiscal 1999, Compaq and Hitachi Cable
accounted for 21% and 13% of our net revenue, respectively. Compaq is both an
OEM and an end-user customer. Because our expense levels are based on our
expectations as to future revenue and to a large extent are fixed in the short
term, a substantial reduction or delay in sales of our products to, or the loss
of any significant reseller, OEM or other customer, or unexpected returns from
resellers could harm our business, operating results and financial condition.
Although our largest customers may vary 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 small number of customers,
particularly in light of the high sales price per unit of our products and the
length of our sales cycles.

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

. our ISP and enterprise network customers can stop purchasing and our
resellers and OEMs can stop marketing our products at any time;

29


. our reseller agreements generally are not exclusive and are for one year
terms, with no obligation of the resellers to renew the agreements;

. our reseller agreements provide for discounts based on expected or actual
volumes of products purchased or resold by the reseller in a given
period; and

. our reseller and OEM agreements generally do not require minimum
purchases.

We have established a program which, under specified conditions, enables
some third party resellers to return products to us. The amount of potential
product returns is estimated and provided for in the period of the sale. Some
of our OEM agreements also provide manufacturing rights and access to our
source code upon the occurrence of specified conditions of default. If we were
to default on these agreements, our OEMs could use our source code to develop
and manufacture competing products, which would negatively affect our
performance and ability to compete.

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

The timing of our sales revenue is difficult to predict because of our
reliance on indirect sales channels and the length and variability of our sales
cycle. Our products have a relatively high sales price per unit, and often
represent a significant and strategic decision by an enterprise regarding its
communications infrastructure. Accordingly, the purchase of our products
typically involves significant internal procedures associated with the
evaluation, testing, implementation and acceptance of new technologies. This
evaluation process frequently results in a lengthy sales process, typically
ranging from three months to longer than a year, and subjects the sales cycle
associated with the purchase of our products to a number of significant risks,
including budgetary constraints and internal acceptance reviews. The length of
our sales cycle also may vary substantially from customer to customer. While
our customers are evaluating our products and before they may place an order
with us, we may incur substantial sales and marketing expenses and expend
significant management effort. Consequently, if sales forecasted from a
specific customer for a particular quarter are not realized in that quarter, we
may be unable to compensate for the shortfall, which could harm our operating
results.

Extreme Purchases Several Key Components for Products From Single or Limited
Sources and Could Lose Sales if These Sources Fail to Fill Its 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 gigabit interface
converter transceivers, or GBICs, are currently in short supply. While we have
been able to meet our needs to date, we are likely to encounter shortages and
delays in obtaining these or other components in the future which could
materially adversely affect our ability to meet customer orders. Our principal
sole sourced components include:

. ASICs;

. microprocessors;

. programmable integrated circuits;

. selected other integrated circuits;

. cables; and

. custom-tooled sheet metal.

Our principal limited sourced components include:

. flash memories;


30


. dynamic and static random access memories, commonly known as DRAMs and
SRAMs, respectively; and

. printed circuit boards.

We use a rolling six-month forecast based on anticipated product orders 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 orders do not
match forecasts, we may have excess or inadequate inventory of certain
materials and components, which could materially adversely affect our operating
results and financial condition. From time to time we have experienced
shortages and allocations of certain components, resulting in delays in filling
orders. In addition, during the development of our products we have experienced
delays in the prototyping of our ASICs, which in turn has led to delays in
product introductions.

Extreme Needs to Expand Its Manufacturing Operations and Depends on Contract
Manufacturers for Substantially All of Its Manufacturing Requirements

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 third party manufacturing vendors to manufacture our products. We
currently subcontract substantially all of our manufacturing to two companies--
Flextronics International, Ltd., located in San Jose, California, which
manufactures our Summit1, Summit2 and Summit4 and BlackDiamond products, and
MCMS, Inc., located in Boise, Idaho, which manufactures our Summit24 and
Summit48 products. We have experienced a delay in product shipments from a
contract manufacturer in the past, which in turn delayed product shipments to
our customers. We may in the future experience similar or other problems, such
as inferior quality and insufficient quantity of product, any of which could
materially adversely affect our business and operating results. There can be no
assurance that 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 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
the loss of either of our contract manufacturers would cause a delay in our
ability to fulfill orders while we obtain a replacement manufacturer and would
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 as a result of volume
efficiencies. 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.

If Extreme Loses Key Personnel or is Unable to Hire Additional Qualified
Personnel as Necessary, It May Not Be Able to Successfully Manage Its Business
or Achieve Its Objectives

Our success depends to a significant degree upon the continued contributions
of our key management, engineering, sales and marketing and manufacturing
personnel, many of whom would be difficult to replace. In particular, we
believe that our future success is highly dependent on Gordon Stitt, Chairman,
President and Chief Executive Officer, Stephen Haddock, Vice President and
Chief Technical Officer, and Herb Schneider, Vice President of Engineering. We
neither have employment contracts with nor key person life insurance on any of
our key personnel.

31


We believe our future success will also depend in large part upon our
ability to attract and retain highly skilled managerial, engineering, sales and
marketing, finance and manufacturing personnel. Competition for these personnel
is intense, especially in the San Francisco Bay Area, and we have had
difficulty hiring employees in the timeframe we desire, particularly software
engineers. 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 required personnel, particularly engineers and sales
personnel, could make it difficult for us to manage our business and meet key
objectives, such as product introductions, on time. 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 received claims like this from other companies and,
although to date they have not resulted in material litigation, we cannot
assure you that we will not receive additional claims in the future as we seek
to hire qualified personnel or that such claims will not result in material
litigation. We could incur substantial costs in defending ourselves against any
such claims, regardless of the merits of such claims.

Extreme's Products Must Comply With Evolving Industry Standards and Complex
Government Regulations or Its Products May Not Be Widely Accepted, Which May
Prevent Extreme From Sustaining Its Revenues 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 changes, 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. In addition, in the
United States, our products must comply with various regulations and standards
defined by the Federal Communications Commission and Underwriters Laboratories.
Internationally, products that we develop may be required to comply with
standards established by telecommunications authorities in various countries as
well as with 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 would
not be able to sell our products where these standards or regulations apply,
which may prevent us from sustaining our revenues or achieving profitability.

Extreme Needs to Expand Its Sales and Support Organizations to Increase Market
Acceptance of Its Products and If It Fails to Do So, Extreme Will Not Be Able
to Increase Revenues

Our products and services require a sophisticated sales effort targeted at
several levels within a prospective customer's organization. Unless we expand
our sales force we will not be able to increase revenues. We have recently
expanded our sales force and plan to hire additional sales personnel. However,
competition for qualified sales personnel is intense, and we might not be able
to hire the kind and number of sales personnel we are targeting.

We currently have a small customer service and support organization and will
need to increase our staff to support new customers and the expanding needs of
existing customers. The design and installation of networking products can be
complex; accordingly, we need highly-trained customer service and support
personnel particularly for large ISP and enterprise network customers. Hiring
customer service and support personnel is very competitive in our industry due
to the limited number of people available with the necessary technical skills
and understanding of our products.

Extreme Depends Upon International Sales for Much of Its Revenue and Extreme's
Ability to Sustain and Increase Its International Sales Depends on Successfully
Expanding Its International Operations

Our ability to grow will depend in part on the expansion of international
sales and operations which have and are expected to constitute a significant
portion of our sales. Sales to customers outside of North America

32


accounted for approximately 61% and 53% of our net revenue in fiscal 1998 and
fiscal 1999, respectively. Our international sales primarily depend on our
resellers and OEMs. The failure of our resellers and OEMs to sell our products
internationally would limit our ability to sustain and grow our revenue. In
addition, there are a number of risks arising from our international business,
including:

. longer accounts receivable collection cycles;

. difficulties in managing operations across disparate geographic areas;

. difficulties associated with enforcing agreements through foreign legal
systems;

. payment of operating expenses in local currencies, which subjects us to
risks of currency fluctuations;

. import or export licensing requirements;

. potential adverse tax consequences; and

. unexpected changes in regulatory requirements.

Our international sales currently are U.S. dollar-denominated. As a result,
an increase 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 subject us to fluctuations in exchange rates between the
U.S. dollar and the particular local currency. If we do so, we may determine to
engage in hedging transactions to minimize the risk of such fluctuations.
However, if we are not successful in managing such hedging transactions, we
could incur losses from hedging activities. Because we currently denominate
sales in U.S. dollars, we do not anticipate that the adoption of the Euro as a
functional legal currency of certain European countries will materially affect
our business.

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

As part of our business strategy, we expect to review acquisition and
strategic investment prospects that would complement our current product
offerings, augment our market coverage or enhance our technical capabilities,
or that may otherwise offer growth opportunities. While we have no current
agreements or negotiations underway with respect to any such acquisitions, we
are reviewing investments in new businesses and we may acquire businesses,
products or technologies in the future. In the event of any future
acquisitions, we could:

. issue equity securities which would dilute current stockholders'
percentage ownership;

. incur substantial debt; or

. assume contingent liabilities.

These actions by us could materially adversely affect our operating results
and/or the price of our common stock. Acquisitions and investment activities
also entail numerous risks, including:

. difficulties in the assimilation of acquired operations, technologies or
products;

. unanticipated costs associated with the acquisition or investment
transaction;

. diversion of management's attention from other business concerns;

. adverse effects on existing business relationships with suppliers and
customers;

. risks associated with entering markets in which we have no or limited
prior experience; and

. potential loss of key employees of acquired organizations.

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 materially adversely affect our
business, operating results and financial condition.

33


Extreme May Need Additional Capital to Fund Its Future Operations Which, If It
Is Not Available When Needed, Extreme May Need to Reduce Its Planned
Development and Marketing Efforts, Which May Reduce Its Revenues and Prevent
Extreme From Achieving Profitability

We believe that our existing working capital, proceeds from the initial
public offering in April 1999 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 our reseller and distribution
channels and associated support personnel is expected to require a significant
commitment of resources. In addition, if the market for Layer 3 switches were
to develop more slowly than anticipated or if we fail to establish significant
market share and achieve a meaningful level of revenues, we may continue to
utilize significant amounts of capital. As a result, we could be required to
raise substantial 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 to existing stockholders. If
additional funds are raised through the issuance of debt securities, such
securities may have rights, preferences and privileges senior to holders of
common stock and the term of such debt could impose restrictions on our
operations. We cannot assure you that such additional capital, if required,
will be available on acceptable terms, or at all. 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 harm our business,
financial condition and operating results.

If Extreme's Products Contain Undetected Software or Hardware Errors, Extreme
Could Incur Significant Unexpected Expenses and Lost Sales

Network products frequently contain undetected software or hardware errors
when first introduced or as new versions are released. We have experienced such
errors in the past in connection with new products and product upgrades. We
expect that such errors will be found from time to time in new or enhanced
products after commencement of commercial shipments. These problems may
materially adversely affect our business by causing us to incur significant
warranty and repair costs, diverting the attention of our engineering personnel
from our product development efforts and causing significant customer relations
problems.

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 source of the problem. The occurrence of hardware and software
errors, whether caused by our products or another vendor's products, could
result in the delay or loss of market acceptance of our products and any
necessary revisions may result in the incurrence of significant expenses. The
occurrence of any such problems would likely have a material adverse effect on
our business, operating results and financial condition.

Extreme's Limited Ability to Protect Its Intellectual Property May Adversely
Affect Its 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.

We also 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 obtain and use our products or technology.

34


If Extreme or Its Key Suppliers and Customers Fail to Be Year 2000 Compliant,
Extreme's Business May Be Severely Disrupted And Its Revenues May Decline

The year 2000 computer issue creates a risk for us. If systems do not
correctly recognize date information when the year changes to 2000, there could
be an adverse impact on our operations. The risk exists in four areas:

. potential warranty or other claims from our customers;

. systems we use to run our business;

. systems used by our suppliers; and

. the potential reduced spending by other companies on networking solutions
as a result of significant information systems spending on year 2000
remediation.

We are currently evaluating our exposure in all of these areas.

We are conducting an inventory and evaluation of the information systems
used to run our business. Systems which have been and may be identified as non-
compliant have been or will be upgraded or replaced. For the year 2000 non-
compliance issues identified to date, the cost of remediation is not expected
to be material to our operating results. However, if implementation of
replacement systems is delayed, or if significant new non-compliance issues are
identified, our operating results or financial condition could be materially
adversely affected.

We are checking the websites of our suppliers to determine if these
suppliers are certifying that the components they provide us are year 2000
compliant. To date, we believe all critical components that we obtain from
third party suppliers are year 2000 compliant, except that Microsoft has not
indicated that Windows 95 and its office mail programs are year 2000 compliant.
We expect that we will be able to resolve any significant year 2000 problems
with Microsoft and any other third-party suppliers of components; however,
there can be no assurance that these suppliers will resolve any or all year
2000 problems before the occurrence of a material disruption to the operation
of our business. Any failure of these third parties to timely resolve year 2000
problems with their systems could have a material adverse effect on our
business, operating results and financial condition.

Since all customer situations cannot be anticipated, we may see an increase
in warranty and other claims as a result of the year 2000 transition. In
addition, litigation regarding year 2000 compliance issues is expected to
escalate. For these reasons, the impact of customer claims could have a
material adverse impact on our operating results or financial condition.

Businesses that face year 2000 compliance issues may require significant
hardware and software upgrades or modifications to their computer systems and
applications. These companies may plan to devote a substantial portion of their
information systems' spending to fund such upgrades and modifications and
divert spending away from networking solutions. This change in customers'
spending patterns could materially adversely impact our business, operating
results or financial condition.

Provisions in Extreme's Charter or Agreements May Delay or Prevent a Change of
Control

Provisions in our certificate of incorporation and bylaws may delay or
prevent a change of control or changes in our management. These provisions
include:

. the division of the board of directors into three separate classes;

. the right of the board of directors to elect a director to fill a vacancy
created by the expansion of the board of directors;

. the ability of the board of directors to alter our bylaws without getting
stockholder approval; and

35


. the requirement that at least 10% of the outstanding shares are needed to
call a special meeting of stockholders.

Furthermore, we are subject to the provisions of section 203 of the Delaware
General Corporation Law. These provisions prohibit large stockholders, in
particular those owning 15% or more of the outstanding voting stock, from
consummating a merger or combination with a corporation unless this stockholder
receives board approval for the transaction or 66 2/3% of the shares of voting
stock not owned by the stockholder approve the merger or combination. Further,
we have investor agreements with Compaq, Siemens and 3Com which require us to
give these companies notice if we receive an acquisition offer or if we intend
to pursue one.

Substantial Future Sales of Extreme's Common Stock in the Public Market Could
Cause Its Stock Price to Fall

The market price of our common stock could drop as a result of sales of a
large number of shares in the market or in response to the perception that
these sales could occur. All of the 8,050,000 shares sold in the initial public
offering are freely tradeable, with the 41,295,230 other shares outstanding,
based on the number of shares outstanding as of June 30, 1999, are "restricted
securities" as defined in Rule 144 of the Securities Act of 1933, and tradable
in the near future.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Sensitivity

The primary objective of our investment activities is to preserve principal
while at the same time maximizing 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 investment that are subject to
market risk by range of expected maturity and weighted-average interest rates
as of June 30, 1999. This table does not include money market funds because
those funds are not subject to market risk.

Exchange Rate Sensitivity

Currently, the majority of our sales and expenses are denominated in U.S.
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 30, 1999 and expect to continue to do so,
we do not anticipate that foreign exchange gains or losses will be significant.
We have not engaged in foreign currency hedging activities to date, however, we
may do so in the future.

EXTREME NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Nature of Operations

Extreme Networks, Inc. ("Extreme" or the "Company") was incorporated in the
state of California on May 8, 1996 and was reincorporated in the state of
Delaware on January 7, 1999. The Company is engaged in the design, development,
manufacture and sale of high performance networking products based on Gigabit
Ethernet technology. The financial operations for the period ended June 30,
1996 were insignificant (generating a net loss of approximately $94,000) and
have been combined with Extreme's results for the year ended June 30, 1997.
Through June 30, 1997, Extreme was in the development stage. Extreme has
incurred operating losses to date and has an accumulated deficit of $23.5
million at June 30, 1999.

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of Extreme and
its wholly-owned subsidiaries. All significant inter-company balances and
transactions have been eliminated. Assets and liabilities of foreign operations
are translated to U.S. dollars at current rates of exchange, and revenues and
expenses are translated using weighted average rates. Foreign currency
transaction gains and losses have not been material. Gains and losses from
foreign currency translation are included as a separate component of
comprehensive income.

Certain items previously reported in specific financial statement captions
have been reclassified to conform with the 1999 presentation.

Accounting Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that materially affect the amounts reported in the financial
statements. Actual results could differ materially from these estimates.

Cash Equivalents and Short-Term Investments

Extreme considers all highly liquid investment securities with maturity from
date of purchase of three months or less to be cash equivalents and investment
securities with maturity from date of purchase of more than three months but
less than one year, to be short-term investments.

Management determines the appropriate classification of debt and equity
securities at the time of purchase and reevaluates such designation as of each
balance sheet date. To date, all marketable securities have been classified as
available-for-sale and are carried at fair value, with unrealized gains and
losses, when material, reported net-of-tax as a separate component of
comprehensive income. 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.

Fair Value of Financial Instruments

The estimated fair value amounts have been determined by Extreme using
available market information and valuation methodologies considered to be
appropriate. However, considerable judgment is required in interpreting market
data to develop the estimates of fair value. Accordingly, the estimates
presented herein are not necessarily indicative of the amounts that Extreme
could realize in a current market exchange.

The fair value for marketable debt securities is based on quoted market
prices. The carrying value of those securities approximates their fair value.

43


EXTREME NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

The fair value of notes is estimated by discounting the future cash flows
using the current interest rates at which similar loans would be made to
borrowers with similar credit ratings and for the same remaining maturities.
The carrying values of these obligations approximate their respective fair
values.

The fair value of short-term and long-term capital lease obligations is
estimated based on current interest rates available to Extreme for debt
instruments with similar terms, degrees of risk and remaining maturities. The
carrying values of these obligations approximate their respective fair values.

Inventories

Inventories are stated at the lower of cost or market (on a first-in, first-
out basis) and are comprised substantially of finished goods.

Concentration of Credit Risk, Product and Significant Customers and Supplier
Information

Financial instruments that potentially subject Extreme to concentration of
credit risk consist principally of marketable investments and accounts
receivable. Extreme has placed its investments with six high-credit quality
issuers with no more than $2 million due from any one issuer. Extreme sells its
products primarily to United States corporations in the technology marketplace.
Extreme performs ongoing credit evaluations of its customers and generally does
not require collateral. Credit losses have been immaterial and within
management's expectations. Extreme operates solely within one business segment,
the development and marketing of end-to-end LAN switching solutions.
Significant customer concentration in the years ended June 30, 1999 and 1998 is
summarized below. No other customer accounts for more than 10% of Extreme's net
revenues.



Year Ended
June 30,
-------------
1999 1998
----- -----

Customer........................
3Com.......................... -- 25%
Compaq........................ 21% 21%
Hitachi Cable................. 13% --


One supplier currently manufacturers all of Extreme's ASICs which are used
in all of Extreme's networking 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, would
materially adversely affect Extreme's business, operating results and financial
condition. In addition, qualifying additional suppliers can be time-consuming
and expensive and may increase the likelihood of errors. Extreme attempts to
mitigate these risks by working closely with its ASIC supplier regarding
production planning and product introduction timing.

Extreme currently derives substantially all of its revenue from sales of two
product families. Extreme expects that revenue from these two product families
will account for a substantial portion of its revenue for the foreseeable
future. Accordingly, widespread market acceptance of Extreme's product families
is critical to their future success.

Property and Equipment

Property and equipment are stated at cost, net of accumulated amortization
and depreciation. Property and equipment are depreciated on a straight-line
basis over the estimated useful lives of the assets of approximately three
years or the applicable lease term, if shorter. Equipment acquired under
capital lease obligations is amortized over the shorter of the lease term or
the estimated useful lives of the related assets.

EXTREME NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Revenue Recognition

Extreme generally recognizes product revenue at the time of shipment, unless
Extreme has future obligations for installation or has to obtain customer
acceptance in which case revenue is deferred until these obligations are met.
Revenue from service obligations is deferred and recognized on a straight-line
basis over the contractual period. Amounts billed in excess of revenue
recognized are included as deferred revenue in the accompanying consolidated
balance sheets. Extreme has established a program which enables third party
resellers to return up to 15% of their previous month's purchases in exchange
for a purchase order of equal or greater dollar value. The amount of estimated
product returns is provided for in the period of the sale.

Upon shipment to its customers, Extreme provides for the estimated cost to
repair or replace products to be returned under warranty. Extreme's warranty
period is typically 12 months from the date of shipment to the end user.

Foreign Operations

Extreme's foreign offices consist of sales, marketing and support activities
through its foreign subsidiaries and an overseas reseller network. Operating
income generated by the foreign operations of Extreme and their corresponding
identifiable assets were not material in any period presented.

Extreme's export sales represented 53% and 61% of net revenue in 1999 and
1998, respectively. All of the export sales to date have been denominated in
U.S. dollars and were derived from sales to Europe and Asia. Extreme recorded
export sales over 10% (as a percentage of total net revenue) to the following
countries:

----- -----

United Kingdom....................... 8% 30%
Japan................................ 29% 19%
All other export sales to countries
totaling less than 10% each......... 16% 12%


Net Loss Per Share

Basic net loss per share and diluted net loss per share are presented in
conformity with Financial Accounting Standards Board's ("FASB") Statement of
Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share," for all
periods presented.


45


EXTREME NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

In accordance with SFAS No. 128, basic net loss per share has been computed
using the weighted-average number of shares of common stock outstanding during
the period, less shares subject to repurchase. Basic and diluted pro forma net
loss per share for the two years ended June 30, 1999 and 1998, as presented in
the consolidated statements of operations, has been computed as described above
and also gives effect to the conversion of the convertible preferred stock
(using the if-converted method) from the original date of issuance. The
following table presents the calculation of basic and diluted and pro forma
basic and diluted net loss per common share (in thousands, except per share
data):

======== =========

======== =========


Extreme has excluded all convertible preferred stock, warrants for
convertible preferred stock, outstanding stock options and shares subject to
repurchase from the calculation of diluted loss per common share because all
such securities are anti-dilutive for all periods presented. The total numbers
of shares excluded from the calculations of diluted net loss per share was
37,927,370, 36,082,561 and 30,834,912 for the years ended June 30, 1999, 1998
and 1997, respectively. See Note 6 for further information on these securities.

Accounting for Stock-Based Compensation

Extreme's grants of stock options are for a fixed number of shares to
employees with an exercise price equal to the fair value of the shares at the
date of grant. As permitted under SFAS Statement No. 123, "Accounting for
Stock-Based Compensation" ("FAS 123"), Extreme accounts for stock option grants
to employees and directors in accordance with APB Opinion No. 25, "Accounting
for Stock Issued to Employees" ("APB 25") and, accordingly, recognizes no
compensation expense for stock option grants with an exercise price equal to
the fair value of the shares at the date of grant.


46


EXTREME NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Recently Issued Accounting Standards

In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information" ("FAS 131") effective for financial
statements for periods beginning after December 15, 1997. FAS 131 establishes
standards for the way that public business enterprises report financial and
descriptive information about reportable operating segments in annual financial
statements and interim financial reports issued to shareholders. FAS 131
supersedes SFAS No. 14, "Financial Reporting for Segments of a Business
Enterprise," but retains the requirement to report information about major
customers. Extreme adopted FAS 131 effective for its fiscal year ending June
30, 1999. Extreme has determined that it has a single reportable segment.
Management uses one measurement of profitability and does not disaggregate its
business for internal reporting.

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("FAS 133"). Extreme is required to adopt
FAS 133 for the year ending June 30, 2002. FAS 133 establishes methods of
accounting for derivative financial instruments and hedging activities related
to those instruments as well as other hedging activities. Because Extreme
currently holds no derivative financial instruments and does not currently
engage in hedging activities, adoption of FAS 133 is expected to have no
material impact on Extreme's financial condition or results of operations.

In March 1998, the American Institute of Certified Public Accountants issued
SOP 98-1, "Accounting for the Costs of Computer Software Developed or Obtained
for Internal Use." SOP 98-1 requires that entities capitalize certain costs
related to internal use software once certain criteria have been met. Extreme
is required to implement SOP 98-1 for the year ending June 30, 2000. Adoption
of SOP 98-1 is expected to have no material impact on Extreme's financial
condition or results of operations.

3. Property and Equipment

Property and equipment are stated at cost, net of accumulated amortization
and depreciation. Property and equipment are depreciated on a straight-line
basis over the estimated useful lives of the assets of approximately three
years or the applicable lease term, if shorter. Equipment acquired under
capital lease obligations is amortized over the shorter of the lease term or
the estimated useful lives of the related assets. Property and equipment
consist of the following (in thousands):

------- -------

Computer and other related equipment....................... $ 8,661 $ 3,465

Less accumulated depreciation and amortization............. (7,502) (1,769)
------- -------
Property and equipment, net................................ $ 6,506 $ 4,469
======= =======


Included in property and equipment are assets acquired under capital lease
obligations with a cost and related accumulated amortization of approximately
$2,371,000 and $1,494,000, respectively, at June 30, 1999, and approximately
$2,093,000 and $490,000, respectively, at June 30, 1998. The amortization
expense on assets recorded under capital leases is included within depreciation
expense.

4. Notes Payable

In October 1996, Extreme entered into a note payable with a bank that
allowed the Company to borrow up to $400,000. Interest was payable monthly
based on an annual rate of 11%. The note was secured by Extreme's assets. The
note was paid off during the fiscal year ended June 30, 1999.

In November 1996, Extreme entered into a $300,000 note payable agreement
with a leasing company. The note accrued interest monthly based on an annual
rate of 9%. The note was secured by all of Extreme's fixed assets. The note was
paid off during the fiscal year ended June 30, 1999.

In November 1997, Extreme entered into a $2,000,000 note payable with a
leasing company. The note accrued interest monthly based on an annual rate of
9.75%. The note was secured by all of Extreme's fixed assets. The note was paid
off during the fiscal year ended June 30, 1999.

5. Commitments

Extreme had outstanding purchase order commitments for materials of
approximately $26.4 million and $4.4 million at June 30, 1999 and 1998,
respectively. Extreme expects the 1999 purchase orders to be fulfilled and the
related invoices to be paid in fiscal year 2000. Of this amount, the Company
has accrued and expensed approximately $1.1 million of the outstanding purchase
order commitments for materials due to obligations to suppliers as of June 30,
1999. This expense is included within cost of revenue in the year ended June
30, 1999.

The Company has entered into capital equipment lease lines of credit for a
total of $6.0 million, of which approximately $4.0 million remains available at
June 30, 1999. These arrangements are secured by the property and equipment
subject to the leases. Under the terms of these lines of credit, Extreme may
not declare or pay any dividends without prior consent of the lenders.


48


EXTREME NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Extreme has entered into a revolving line of credit for $5.0 million.
Borrowings under this line of credit bear interest at the bank's prime rate. At
June 30, 1999 there were no outstanding borrowings under this line of credit.

In February 1999, Extreme agreed to lease 77,000 square feet to house its
primary facility in Santa Clara, California. The related cost of this lease is
approximately $120,000 per month. The lease expires in December 2002. Extreme
commenced occupancy in March 1999. Rent expense was approximately $759,000,
$712,000 and $220,000 for the years ended June 30, 1999, 1998 and 1997,
respectively.


Future payments under all noncancelable leases at June 30, 1999 are as

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

In May 1996, under a stock purchase agreement, Extreme issued 14,579,999
Series A convertible preferred shares at a price of $.333 per share. In May and
June 1997, under a stock purchase agreement, Extreme issued 8,886,228 Series B
convertible preferred shares at a price of $1.38 per share. In January and
March of 1998, under a stock purchase agreement, Extreme issued 5,595,088
Series C convertible preferred shares at a price of $3.67 per share.

Each share of Series A, B, and C convertible preferred stock was
convertible, at the option of the holder, into one share of common stock,
subject to certain provisions. The outstanding shares of convertible preferred
stock would automatically convert into common stock either upon the close of
business on the day immediately preceding the closing of an underwritten public
offering of common stock under the Securities Act of 1933 in which Extreme
receives at least $10,000,000 in gross proceeds and the price per share is at
least $5.00, or at the election of the holders of at least a majority of each
series of the outstanding shares of preferred stock.

Series A, B, and C convertible preferred stockholders were entitled to
annual noncumulative dividends of $.0267, $.1104, and $.2936, respectively, per
share if and when declared by the board of directors. No dividends were
declared. All outstanding shares of preferred stock were converted to common
shares in Extreme's Initial Public Offering in April 1999. Concurrent with the
initial public offering, each of the 14,579,999 shares of Series A convertible
preferred stock outstanding, each of the 8,886,228 shares of Series B
convertible preferred stock outstanding and each of the 5,595,088 shares of
Series C convertible preferred stock outstanding were converted into one share
of common stock, resulting in an issuance of 29,061,315 shares of common stock.

Preferred Stock

The number of shares of preferred stock authorized to be issued is 2,000,000
with a par value of $0.001 per share. 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
30, 1999, no shares of preferred stock had been issued.

Common Stock

In May 1996, Extreme issued 4,725,000 shares of common stock to founders for
cash. The common stock is subject to repurchase until vested; vesting with
respect to 25% occurs on the first anniversary of the issuance date, with the
balance vesting ratably over a period of three years as specified in the
purchase agreements. At June 30, 1999 and 1998, approximately 591,000 and
1,772,000 shares, respectively, were subject to repurchase at their original
issuance price.

Warrants

In November 1996, Extreme issued warrants to a lease financing company to
purchase 210,000 shares of Series A convertible preferred stock with an
exercise price of $.33 per share, in consideration for equipment leases and a
loan. In July 1997, Extreme issued warrants to the same lease financing company
to purchase 48,347 shares of Series B convertible preferred stock with an
exercise price of $1.38 per share, in consideration for equipment leases.
Concurrent with the initial public offering, these warrants converted into the
right to purchase equivalent number of shares of common stock at the same
exercise price per share. The warrants may be exercised at any time within a
period of (i) 10 years or (ii) 5 years from the effective date of the initial
public offering, whichever is longer. In May 1999, 147,000 of these warrants
were exercised.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


In November 1997, the Company issued warrants to a lease financing company
to purchase 79,051 shares of Series C convertible preferred stock with an
exercise price of $2.53, in consideration for a loan. Concurrent with the
initial public offering, these warrants converted into the right to purchase
equivalent number of shares of common stock at the same exercise price per
share. The warrants may be exercised at any time within a period which expires
the sooner of (i) 10 years or (ii) 3 years from the effective date of the
initial public offering.

In June 1999, Extreme issued fully vested and exercisable warrants to a
customer to purchase 40,000 shares of the Company's common stock with an
exercise price of $58.063 per share. The value of these warrants was
approximately $948,000. This value was expensed in fiscal 1999 as the warrants
were issued in exchange for services rendered.

Deferred Stock Compensation

During the year ended June 30, 1998, in connection with the grant of certain
stock options to employees, Extreme recorded deferred stock compensation of
$437,000 representing the difference between the exercise price and the deemed
fair value of Extreme's common stock on the date such stock options were
granted. Such amount is included as a reduction of stockholders' equity and is
being amortized by charges to operations on a graded vesting method. Extreme
recorded amortization of deferred stock compensation expense of approximately
$172,000 and $68,000 for the years ended June 30, 1999 and 1998, respectively.
At June 30, 1999, Extreme had a total of approximately $197,000 remaining to be
amortized over the corresponding vesting period of each respective option,
generally four years. The amortization expense relates to options awarded to
employees in all operating expense categories.

Amended 1996 Stock Option Plan

In January 1999, the board of directors approved an amendment to the 1996
Stock Option Plan (the "Plan") to (i) increase the share reserve by 5,000,000
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
Plan as the "Amended 1996 Stock Option Plan."

Under the Plan, which was 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 17,014,309 shares have been reserved under the 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 Plan is ten years. Options to purchase
approximately 2,327,779 and 4,297,346 shares of common stock have been
exercised as of June 30, 1999 and 1998, respectively, but are subject to
repurchase until vested. As of June 30, 1999, 5,433,217 shares were available
for future grant under the Plan.

average exercise price of $4.44, $0.84 and $0.05, respectively.

1999 Employee Stock Purchase Plan

In January 1999, the board of directors approved the adoption of Extreme's
1999 Employee Stock Purchase Plan (the "1999 Purchase Plan"). A total of
1,000,000 shares of common stock has been reserved for issuance under the 1999
Purchase Plan. The 1999 Purchase Plan permits eligible employees to acquire
shares of Extreme's common stock through periodic payroll deductions of up to
15% of total compensation. No more than 625 shares may be purchased on any
purchase date per employee. Each offering period will have 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 Extreme's common stock on the first day
of the applicable offering period or on the last day of the respective purchase
period. The initial offering period commenced on the effectiveness of the
initial public offering and will end on April 30, 2000.

Stock-Based Compensation

The Company has elected to continue to follow APB 25 and related
interpretations in accounting for its employee and director stock-based
compensation plans. Because the exercise price of Extreme's employee stock
options equals the market price of the underlying stock on the date of grant,
no compensation expense was recognized.

Pro forma information regarding net income has been determined as if Extreme
had accounted for its stock-based awards to employees under the fair value
method prescribed by FAS 123. The resulting effect on pro forma net income
disclosed is not likely to be representative of the effects on net income on a
pro forma basis in future years, due to subsequent years including additional
grants and years of vesting.

Prior to the Company's initial public offering, the fair value of each
option grant was determined on the date of grant using the minimum value
method. Subsequent to the offering, the fair value of the Company's stock-based
awards to employees was estimated using the Black-Scholes option pricing model.
Except for the volatility assumption which was only used under the Black-
Scholes model, the following weighted-average assumptions were used to perform

FASB Statement No. 109 provides for the recognition of deferred tax assets
if realization of such assets is more likely than not. Based upon the weight of
available evidence, which includes the Company's historical operating
performance and the reported cumulative net losses in all prior years, the
Company has provided a full valuation allowance against its net deferred tax
assets. The Company will continue to evaluate the realizability of the deferred
tax assets on a quarterly basis.

The net valuation allowance decreased by $ 1,019,000 during the year ended
June 30, 1999 and increased by $6,242,000 during the year ended June 30, 1998.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


As of June 30, 1999, the Company had net operating loss carryforwards for
federal and state tax purposes of approximately $4,100,000 and $3,900,000,
respectively. The Company also had federal and state research and development
tax credit carryforwards of approximately $1,202,000 and $918,000,
respectively. The federal and state net operating loss carryforwards will
expire at various dates beginning in 2004 through 2019, if not utilized.

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 and similar state provisions. The annual
limitation may result in the expiration of net operating losses and tax
credits before utilization.

8. Comprehensive Income (Loss)

Extreme adopted SFAS No. 130, "Reporting Comprehensive Income" at December
31, 1998. SFAS 130 establishes new rules for the reporting and display of
comprehensive income and its components; however, the adoption of the
Statement had no impact on the Company's net income (loss) or stockholders'
equity. SFAS 130 requires unrealized gains or losses on the Company's
available-for-sale securities and foreign currency translation adjustments to
be included in other comprehensive income. Prior to adoption of SFAS 130, the
Company had no unrealized gains or losses on available-for-sale securities or
foreign currency translation adjustments.
