Industry Background

The pervasiveness of computing by businesses, organizations and individuals,
and the need to interconnect computing devices to enable widespread
communication, have given rise to the multi-billion dollar computer networking
industry. The explosive growth of the Internet and corporate internal and
external communications needs are driving the recent growth in enterprise and
Internet service provider networks. The complexity of information traveling
over networks is also rapidly increasing with the adoption of bandwidth-
intensive applications that include increasing amounts of data, voice, video
and graphics. The increase in users, coupled with these new bandwidth-intensive
applications, has resulted in exponential growth in network traffic. This
growth has led to a demand by enterprises, web-based businesses, and Internet
service providers for networking solutions with superior performance and
intelligence capabilities.


1


Evolution of Market Needs

Organizations adopted data networks to connect a limited number of computers
within close proximity, allowing users to share simple, common services, such
as file servers and printers. In these networks, called local area networks or
LANs, traffic patterns were predictable because the majority of traffic resided
within the LAN and remained local to a specific part of the organization.
Widespread Internet usage, the proliferation of client-server applications and
the adoption of new bandwidth-intensive applications have increased traffic
loads and created unpredictable traffic patterns. Today, the majority of
traffic traverses the boundaries of the LAN to networks outside of the LAN.
Such communication traditionally required an organization to utilize costly
long distance carrier services that often provided inadequate performance. As a
result of today's traffic flows, enterprises increasingly require low cost,
high performance networking equipment to enable effective communications across
geographically dispersed networks, known as MANs and WANs.

Applying enterprise performance requirements to the growing set of web-based
organizations and Internet service providers magnifies our challenges. As their
customers have increasingly become dependent on Internet access, these new web-
based companies and Internet service providers demand networking solutions that
ensure the highest levels of performance and scalability. Similar to enterprise
needs, web-oriented organizations require low cost, high performance solutions
for both their internal networks and access to the Internet. The exponential
growth of Internet traffic, combined with the business critical nature of the
services that Internet service providers provide, necessitates heightened
requirements for reliability.

Evolution of Network Solutions

Early LANs consisted of hubs, which enabled multiple users to share network
resources, and software-based routers, which supported multiple protocols to
move traffic around the network. Increased use of bandwidth-intensive
applications and a larger number of users strained these early network
infrastructures, making it increasingly difficult for them to handle new
applications while still performing at an acceptable speed. Network devices
known as Layer 2 switches replaced hubs to provide dedicated bandwidth to
users, while Fast Ethernet technology was introduced to provide data
transmission speeds of 100 Mbps, or ten times faster than original hubs.
Despite these improvements, the installed base of traditional routers, relying
on software to analyze network traffic, was unable to accommodate increased
data speeds and changing traffic patterns and became the new network
bottleneck.

Two new technologies, Gigabit Ethernet, capable of data transmission speeds
of 1000 Mbps, and Layer 3 switching, evolved in parallel to handle growing and
unpredictable traffic patterns and address the performance needs of bandwidth-
intensive applications. Gigabit Ethernet-based Layer 3 switches combine Gigabit
transmission speeds with the forwarding capabilities of software-based routers.
In Layer 3 switches, the software forwarding capabilities that enabled early
routers to move traffic around the network perform this function in hardware,
integrated on application-specific integrated circuits, or ASICs, built into
the switch. This integration enables manufacturers to develop Layer 3 switches
at lower costs while improving network performance.

Next Generation Needs and Solutions

As enterprises, web-based businesses, and Internet service providers seek to
accommodate network user needs, adding bandwidth alone is not an adequate
solution. Due to the increased use of multiple traffic types for many
applications, enterprises, web-based businesses, and Internet service providers
have an acute need for solutions that provide network intelligence to
distinguish among and prioritize different types of traffic and regulate the
network response to traffic. Particularly for anyone supporting electronic
business on the web, including Internet service providers, network intelligence
allows them to maintain network reliability and offer differentiated, fee-based
quality of service.

To address these needs for network intelligence, a new class of device,
Internet traffic management systems, also known as Layer 4-7 switches, has
emerged as a complement to the performance capabilities of

2


existing Layer 3 switches. These switches provide increased network
intelligence, and therefore greater network efficiency, by utilizing
information about the application and the end user to intelligently direct the
traffic to its intended destination. Both classes of switches are necessary
components of a comprehensive networking solution. Layer 3 switches provide the
bandwidth and routing needed to support new applications while Internet traffic
management systems give enterprises, web-based businesses, and Internet service
providers the intelligence to control information delivery. Key Internet
traffic management capabilities include the ability to:

. enhance server performance and reliability by distributing traffic across
multiple servers that support Internet applications;

. scale server farms infrastructures by using the inherent capabilities of
the load balancing devices to removal of traditional network design
constraints;

. increase network security by detecting, stopping and identifying the
source of a hacker attack;

. improve Internet response time by inspecting an end user's web site
address and sending traffic to a specific server that hosts the desired
content; and

. reduce WAN operating costs and improve Internet response time by
redirecting web traffic destined for remote Internet hosts to a group of
local cache servers.

The challenge to the networking company is to provide cost-effective, higher
bandwidth solutions and the increased intelligence required to meet new network
demands placed on enterprises, web-based businesses, and Internet service
providers. Alternatives to Gigabit Ethernet technology, such as asynchronous
transfer mode, are complex and expensive, and do not utilize existing
networking investments or provide network intelligence capabilities. Although
existing Layer 2 and Layer 3 switches utilize Gigabit Ethernet technology, they
often do not scale to span the entire network or provide the performance
required by today's network users. Existing Layer 3 switches, although
essential to the performance of the network, do not incorporate the Internet
traffic management intelligence or capabilities necessary to provide traffic
direction.

A large market has emerged for a broad range of high performance, cost-
effective switching solutions with network intelligence capabilities that
address the needs of enterprises, web-based businesses, and Internet service
providers. Collaborative Research, an independent research and consulting firm
specializing in the Internet traffic management switching market, estimates in
a February 1999 report that the Internet traffic management switching market
totaled $130 million in 1998 and is expected to grow to $1.0 billion in 2002.
Dell'Oro Group estimates in a March 1999 report that the Layer 3 LAN switching
market totaled $637 million in 1998 and is expected to increase to $3.9 billion
in 2002.

maintains direct relationships with key accounts and strategic customers. To a
lesser extent, our field organization also works with resellers to assist in
communicating product benefits to end user customers and proposing networking
solutions. As of December 31, 1999, our field organization included over 95
sales representatives and system engineers. In addition, as of December 31,
1999, we maintained field offices in 35 major metropolitan areas in the United
States.

8


Domestic resellers. Our domestic resellers include regional networking
system resellers and vertical resellers who focus on specific markets such as
small Internet service providers. We provide sales and marketing assistance and
training to our resellers, who in turn provide first level support to end-user
customers. We intend to leverage our relationship with key resellers to
penetrate select vertical markets.

International sales. Product fulfillment and first level support are
provided by resellers and integrators. Our international resellers include
Mitsui in Japan, Samsung in Korea, Mitech in the United Kingdom, Boreal in
France and Pan Dacom in Germany. We also provide field support in key Canadian,
European and Asia Pacific locations including Toronto, London, Paris,
Frankfurt, Munich and Taipei. We intend to expand our international presence
through additional sales and engineering personnel and through the addition of
key resellers and integrators. For fiscal 1999, domestic sales in the U.S.
accounted for 82% of our revenue. No other country accounted for greater than
or equal to 10% of our revenue.

OEM. We established an OEM relationship with Hewlett-Packard in January
1999. Pursuant to our agreement, Hewlett-Packard markets and sells our products
on a private label basis through its worldwide sales force. Hewlett-Packard
also purchases our products for use in its internal networks. For fiscal 1999,
sales to Hewlett-Packard accounted for 14% of our revenue. Our agreement with
Hewlett-Packard continues until May 18, 2000, unless terminated earlier for a
material breach by either party. The agreement automatically renews for two
additional one year periods, unless the agreement is terminated within 60 days
prior to the end of any period. This agreement provides that Hewlett-Packard
may postpone, cancel, increase or decrease any order made under the agreement
without penalty.

Lease financing program. In January 2000, we established Foundry Commercial
Credit, a private-label leasing program, to offer our customers standardized
solution packages that combine Foundry's high performance end-to-end switching
solutions with innovative lease financing options. Foundry Commercial Credit is
being administered by Heller Financial, Inc. (NYSE: HF), a worldwide commercial
finance company. Foundry's leasing program will be marketed through a direct
sales force and authorized resellers in the United States and other key markets
in Europe, Latin America and Asia Pacific.

Marketing programs. We have numerous marketing programs designed to inform
existing and potential customers, as well as resellers and OEMs, about the
capabilities and benefits of our company and products. Our marketing efforts
also support the sale and distribution of our products through our field
organizations and channels. Our marketing efforts include advertising, public
relations, participation in industry trade shows and conferences, participation
in independent third-party product tests, presentations and our web site. We
have begun an e-commerce initiative directed at existing customers and
resellers.

Customer Service and Support

Our service and support organization maintains and supports our products
sold by our field organization to end users. Customer service revenue was 1.0%
and 1.7% of our revenue for 1998 and 1999, respectively. Our resellers and OEM
are responsible for installation, maintenance and support services to their
customers. We may offer limited assistance to our resellers and OEM in
providing service and support to their end user customers.

TechNet, our comprehensive suite of service and support options, provides
customers with a variety of programs to meet specific support needs. TechNet
Gold gives customer network operations the highest level of priority and our
full range of services. TechNet Silver provides customers with all the tools
needed to optimize network performance and uptime. TechNet Bronze extends
warranty support with software updates and telephone and online support.

In December 1999, we opened our regional Centers-of-Excellence in Reston,
Virginia; Irvine, California; and Bracknell, Berkshire in the United Kingdom.
Foundry's Centers-of-Excellence locations are fully equipped to demonstrate
Foundry's award-winning high performance LAN and LAN/WAN products and to
support interoperability testing and hands-on training for customers. These
regional centers also include executive briefing centers and serve as regional
technical support centers, with Foundry sparing depots. The centers allow
Foundry to continue to deliver superior customer service and quality products
to its customers while increasing the variety of support programs to their
rapidly growing installed base.

Manufacturing

We operate under a modified "turn key" process utilizing strategic
manufacturing partners that are ISO 9000 certified and have global
manufacturing capabilities. We maintain control and procurement responsibility
for all proprietary components. All designs, documentation, selection of
approved suppliers, quality control and repairs are performed at our
facilities. In 1999, we transitioned our assembly and testing functions from
our Sunnyvale facility to our manufacturing partners in order to realize lower
costs and higher volume efficiencies. Our approach to manufacturing provides
the flexibility of outsourcing while maintaining quality control of delivered
products to customers. We have selected this approach to ensure our ability to
respond to rapid growth and sudden market shifts.

We currently have two primary manufacturing partners. One partner,
Celestica, located in San Jose, California, assembles and tests our printed
circuit boards. The other partner, Hadco, located in Santa Clara, California,
assembles and tests our backplane products. Both companies are ISO certified
and have global manufacturing facilities providing full back-up capability and
local content for foreign sales if required. We perform all prototype and pre-
production procurement and component qualification with support from our
manufacturing partners. Any interruptions in the operations of either of these
manufacturing partners or delays in their shipment of products would negatively
impact our ability to meet scheduled product deliveries to our customers. We
design all ASICs, printed circuit boards and sheet metal while working closely
with semiconductor partners on future component selection and design support.
All materials used in our products are processed through a full qualification
cycle and controlled by use of an "Approved Vendor Listing" that must be
followed by our sources. We perform extensive testing of all our products
including in-circuit testing of all printed circuit board assemblies, full
functional testing, elevated temperature burn-in and power cycling at maximum
and minimum configuration levels. Please see "Risk Factors--Our reliance on
third-party manufacturing vendors to manufacture our products may cause a delay
in our ability to fill orders" on page 26 for a review of certain risks
associated with our manufacturing operations.

We currently purchase several components from a single source, including
certain integrated circuits, power supplies and long-range optics, which we
believe are readily available from other suppliers. Our proprietary ASICs,
which provide key functionality in our products, are fabricated in foundries
operated by Texas Instruments. An alternative supply for these ASICs could not
be readily obtained.

We acquire these components through purchase orders and have no long-term
commitments regarding supply or price from these suppliers. The material terms
of these orders typically involve the quantity of supply ordered by us, the
purchase price of the components, lead time and the shipping arrangements. In
the event one of these suppliers, in particular, Texas Instruments, materially
delays its supply to us or one of them terminates its relationship with us, we
may not be able to find an alternate supplier on a timely basis and, as a
result, our business could be harmed.

Research and Development

Our future success depends on our ability to enhance existing products and
develop new products that incorporate the latest technological developments. We
work with customers and prospects, as well as partners and industry research
organizations, to identify and implement new solutions that meet the current
and future needs of enterprises, web-based businesses, and Internet service
providers. Whenever possible, our products are based on industry standards to
ensure interoperability. We intend to continue to support emerging industry
standards integral to our product strategy.

We use a uniform architecture across our product line, including
programmable ASICs, and system and network management software. This enables us
to quickly bring new products and features to market. For example, we shipped
the industry's first Gigabit Ethernet Layer 2 and Layer 3 switch in June 1997.
We are currently developing new switching solutions that provide new levels of
performance, scalability and functionality for the LAN, MAN and LAN/WAN. We
also have engineering efforts focused on cost reduction.

10


As of December 31, 1999, we had an engineering staff of 43 responsible for
hardware design and development, architecture and software development,
documentation and quality assurance. Our research and development expenses
totaled $9.0 million in 1999, $8.8 million in 1998 and $5.4 million in 1997.

Competition

We believe that we compete favorably in the key competitive factors that
impact our markets, including technical expertise, price points, new product
innovation, product features, service and support, brand awareness and
distribution. We intend to remain competitive through ongoing investment in
research and development efforts to enhance existing products and introduce new
products. We will seek to expand our market presence through aggressive
marketing and sales efforts and through the continued implementation of cost
reduction efforts. However, our market is still evolving and we may not be able
to compete successfully against current and future competitors.

The market in which we operate is highly competitive. Cisco Systems
maintains a dominant position in this market and several of its products
compete directly with our products. Cisco's substantial resources and market
dominance have enabled it to reduce prices on its products within a short
period of time following the introduction of these products, which reduces the
margins and profitability of its competitors. Purchasers of networking
solutions may choose Cisco's products because of its longer operating history,
broad product line and strong reputation in the networking market. In addition,
Cisco may have developed or could in the future develop new technologies that
directly compete with our products or render our products obsolete.

In addition to Cisco, we compete with other large public companies, such as
3Com and Nortel Networks, as well as other smaller public and private
companies. 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. Furthermore, companies that do not offer a directly
competitive product to our products could develop new products or enter into
agreements with other networking companies to provide a product that competes
with our products or provides a more complete solution than we can offer.
Additionally, we may face competition from unknown companies and emerging
technologies that may offer new LAN, MAN and LAN/WAN solutions to enterprises,
web-based businesses, and Internet service providers.

Intellectual Property

Our success and ability to compete are substantially dependent upon our
internally developed technology and know-how. Our proprietary technology
includes our ASICs, our IronCore hardware architecture, and our IronWare and
Internet IronWare software. Different versions and combinations of these
proprietary technologies are implemented across our product offerings. We rely
on a combination of copyright, trademark and trade secret laws and restrictions
on disclosure to protect our intellectual property rights in these proprietary
technologies. We do not own any patents nor do we have any patent applications
pending. We may not have taken actions that adequately protect our intellectual
property rights.

We provide software to customers under license agreements included in the
packaged software. These agreements are not negotiated with or signed by the
licensee, and thus may not be enforceable in some jurisdictions. Despite our
efforts to protect our proprietary rights through confidentiality and license
agreements, unauthorized parties may attempt to copy or otherwise obtain and
use our products or technology. These precautions may not prevent
misappropriation or infringement of our intellectual property. Monitoring
unauthorized use of our products is difficult and the steps we have taken may
not 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.

Our industry is characterized by the existence of a large number of patents
and frequent claims and related litigation regarding patent and other
intellectual property rights. In particular, leading companies in the
networking markets have extensive patent portfolios with respect to networking
technology, while we do not currently own any patents or have any patent
applications pending. In July 1999, we received a letter from

11


Resonate, Inc., alleging that our ServerIron products infringe one of its
patents. Based on the advice of our patent counsel, we do not believe that our
current ServerIron products infringe Resonate's patent. We have and intend to
continue to contest this claim vigorously. Although we have had no
communication with Resonate on this issue since December 1999, these kinds of
disputes are subject to inherent uncertainties and, therefore, we cannot assure
you that we will prevail in our objection to this claim, nor can we assure you
that this dispute will not result in litigation or that an adverse result or
judgment will not adversely affect our financial condition.

From time to time, other third parties, including leading companies, have
asserted against others and may assert against us exclusive patent, copyright,
trademark and other intellectual property rights to technologies and related
standards that are important to us. Third parties may assert claims or initiate
litigation against us or our manufacturers, suppliers or customers alleging
infringement of their proprietary rights with respect to our existing or future
products. Any of these 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 license agreements. These royalty or license agreements, if
required, may not be available on acceptable terms, if at all. If there is a
successful claim of infringement or if we fail to develop non-infringing
technology or license the proprietary rights on a timely basis, our business
would be harmed.

Employees

As of December 31, 1999, we had 222 employees, including 123 in sales and
marketing, 43 in engineering, 35 in manufacturing and 21 in general and
administrative functions. We are not subject to any collective bargaining
agreements and believe our employee relations are good.

Dividend Policy

The Company has never paid cash dividends on its capital stock. The Company
currently anticipates that it will retain all available funds for use in its
business and does not anticipate paying cash dividends in the foreseeable
future.

Unregistered Securities Sold in 1999

In 1999, we issued 2,923,072 shares of common stock pursuant to the exercise
of stock options at exercise prices ranging from $0.03 to $11.50 per share.
These stock options were granted under our 1996 Stock Plan prior to our initial
public offering. Our issuance of these shares of common stock was exempt from
registration under the Securities Act of 1933, as amended (the "Securities
Act") in reliance on Rule 701 promulgated under the Securities Act.

In June 1999, we issued 375,000 shares of Series C preferred stock to one
investor, a family trust of which Andrew K. Ludwick, a director of Foundry, is
trustee, for an aggregate cash consideration of $1,000,000. Our issuance of
this stock was exempt from registration under the Securities Act in reliance on
Section 4(2) of the Securities Act.

In September 1999, we issued 150,000 shares of common stock pursuant to the
exercise of a nonstatutory stock option at an exercise price of $0.83 per
share. This stock option was granted to a key executive outside of the 1996
Stock Plan prior to our initial public offering. Our issuance of this stock was
exempt from registration under the Securities Act in reliance on Rule 701
promulgated under the Securities Act.

In November 1999, we issued 89,640 shares of common stock to an equipment
lessor upon the exercise of a warrant based on an exercise price of $0.33 per
share. Our issuance of this stock was exempt from registration under the
Securities Act in reliance on Section 4(2) of the Securities Act.

Use of Proceeds from Sales of Registered Securities

On September 27, 1999, in connection with our initial public offering, a
Registration Statement on Form S-1 (No. 333-82577) was declared effective by
the Securities and Exchange Commission. The offering commenced on September 28,
1999 and 11,500,000 shares of our common stock were offered and sold for our
account at a price of $12.50 per share, generating gross offering proceeds of
$143,750,000. After deducting approximately $10,062,500 in underwriting
discounts and $1,856,700 in other related expenses, the net proceeds of the
offering were approximately $131,830,800.

We expect to use the net proceeds of the offering for working capital and
general corporate purposes, including increased spending on sales and
marketing, customer support, research and development, expansion of our
operational and administrative infrastructure, and the leasing of additional
facilities. Specific amounts for these purposes have not been determined. In
addition, we may use a portion of our cash and short-term investments to
acquire or invest in complementary businesses, technologies, product lines or
products.

14


However, we have no current plans, agreements or commitments with respect to
any such acquisition, and we are not currently engaged in any negotiations with
respect to any such transaction. We are currently investing our cash in short-
term, interest-bearing, investment grade securities.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

The following discussion and analysis of our financial condition and results
of operations should be read together with "Selected Financial Data" and our
financial statements and related notes appearing elsewhere in this Form 10-K.
This discussion and analysis contains forward-looking statements that involve
risks, uncertainties and assumptions. The actual results may differ materially
from those anticipated in these forward-looking statements as a result of many
factors, including but not limited to those discussed in the section entitled
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Risk Factors That May Affect Future Results and Market Price of
Stock." Readers are cautioned not to place undue reliance on these forward-
looking statements, which reflect management's opinions only as of the date
hereof. The Company undertakes no obligation to revise or publicly release the
results of any revision to these forward-looking statements. Readers should
carefully review the risk factors described in this document as well as in
other documents the Company files from time to time with the Securities and
Exchange Commission, including the Quarterly Reports on Form 10-Q to be filed
by the Company in fiscal year 2000.

Overview

Foundry designs, develops, manufactures and markets a comprehensive, end-to-
end suite of high performance networking products for enterprises, educational
institutions, government agencies, web-hosting companies, Application Service
Providers (ASPs), electronic banking and finance service providers, and
Internet service providers. From our inception in May 1996 through April 1997,
we were engaged primarily in research and development activities and did not
generate any revenue. A substantial portion of our operating expenses during
this period was related to the design and development of our custom ASICs,
software development and testing prototype designs. We commenced commercial
shipments of our FastIron workgroup Layer 2 switch in May 1997, the initial
product released in our family of stackable products. We shipped NetIron, our
first generation Layer 3 switch, in June 1997. During the second quarter of
1998, we shipped the first products in our Layer 4-7 ServerIron family. We
shipped BigIron, our second generation of midsize and large-scale chassis-based
products, in the third quarter of 1998. Since the first quarter of 1998, our
revenue has increased every quarter, and we were profitable in each quarter of
1999, although we cannot assure you that these results will be indicative of
future performance.

We derive our revenue substantially from sales of our stackable and chassis-
based products, including fees for customer support services related to our
products. We market and sell our products primarily through a direct sales and
marketing organization and, to a lesser extent through resellers and through
our OEM relationship with Hewlett-Packard. We have sales representatives in the
United States, Singapore, Italy, Canada, France, Sweden, China, Netherlands,
Germany, Taiwan and the United Kingdom. We have made significant investments to
expand our international operations and expect international revenue to
increase as a percentage of total revenue. Currently, a majority of our
international sales are denominated in U.S. dollars. We generally recognize
product revenue upon shipment to customers. Revenue from customer support
services is deferred and recognized on a straight-line basis over the
contractual period.

We expect the average selling price of our products to decline due to a
number of factors, including competitive pricing pressures and rapid
technological changes. Our gross margins may be affected by price declines if
we are unable to reduce costs. Furthermore, our gross margins may be affected
by fluctuations in manufacturing volumes, component costs, the mix of product
configurations sold and the mix of distribution channels through which our
products are sold. We generally realize higher gross margins on direct sales to
the end user than on sales through resellers or our OEM. Any significant shift
in revenue through resellers or our OEM, or the loss of any large customer,
reseller or our OEM, could harm our gross margins, operating results and
financial condition.

We rely on two third-party manufacturing vendors that produce different
assemblies for our products. Prior to the first quarter of 1999, we performed
final assembly, testing, quality assurance, manufacturing,

17


engineering, documentation control and repairs of our products at our Sunnyvale
facility. In 1999, we transitioned assembly and testing functions from our
Sunnyvale facility to our manufacturing partners. We realized lower costs and
higher volume efficiencies as a result of this transition in 1999.

In connection with the grant of stock options to employees, we recorded
deferred stock compensation of $4.7 million in 1998 and $17.3 million in 1999,
representing the difference between the exercise price and the deemed fair
market value of our common stock on the date these stock options were granted.
This amount is reflected within stockholders' equity and is being amortized to
operations ratably over the respective vesting periods. We recorded
amortization of deferred stock compensation expense of approximately $727,000
and $9.5 million for the years ended December 31, 1998 and 1999, respectively.
At December 31, 1999, we had approximately $11.8 million remaining to be
amortized over the corresponding vesting period of each respective option,
generally four years. The amortization expense relates to options granted to
employees and directors.

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


Revenue. Revenue was $3.4 million, $17.0 million and $133.5 million in
fiscal 1997, 1998 and 1999, respectively, representing increases of 400% from
fiscal 1997 to 1998, and 685% from fiscal 1998 to 1999. These increases were
due to the market's growing acceptance of Foundry's product offerings, and a
significant increase in Foundry's sales and marketing organizations. We
introduced our BigIron products in the third quarter of 1998 and our ServerIron
products in the second quarter of 1998. Our product introductions coincided
with broad market acceptance of Gigabit Ethernet technology resulting from the
adoption of the Gigabit Ethernet standard in June 1998.

For the year ended December 31, 1999, sales to America Online and Hewlett-
Packard accounted for 11% and 14% of revenue, respectively. Hewlett-Packard is
both an OEM and an end user.

Cost of revenue. Cost of revenue consists primarily of material, labor,
overhead and warranty costs. Cost of revenue was $1.8 million, $8.4 million and
$56.6 million in fiscal 1997, 1998 and 1999, or 54%, 50% and 42% of revenue,
respectively. The decrease as a percentage of revenue was primarily a result of
lower overhead costs due to increased production volume.

18


Research and development. Research and development expenses consist
primarily of salaries and related personnel expenses, prototype expenses
related to the development of our ASICs, software development and testing
costs, and the depreciation of property and equipment related to research and
development activities. Research and development expenses were $5.4 million,
$8.8 million and $9.0 million in fiscal 1997, 1998 and 1999, or 160%, 52% and
7% of revenue, respectively. The increase in absolute dollars was primarily due
to the addition of engineering personnel and related costs. Research and
development costs are expensed as incurred. As a percentage of revenue,
research and development decreased because of the significant increase in
revenue. We believe continued investment in product enhancements and new
product development is critical to attaining our strategic objectives, and as a
result, we expect research and development expenses to continue to increase in
absolute dollars.

Sales and marketing. Sales and marketing expenses consist primarily of
salaries, commissions and related expenses for personnel engaged in marketing,
sales and customer support functions, as well as trade shows, advertising,
promotional expenses and the cost of facilities. Sales and marketing expenses
were $3.4 million, $7.3 million and $23.1 million in fiscal 1997, 1998 and 1999
or 101%, 43% and 17% of revenue, respectively. The increase in absolute dollars
was primarily due to the addition of sales and marketing personnel and
increased commission expenses resulting from significantly higher sales. As a
percentage of revenue, sales and marketing expenses decreased because of the
significant increase in revenue. We expect these expenses to increase in
absolute dollars as we continue to build our field sales and support
organizations and expand sales and marketing activities in the future.

General and administrative. General and administrative expenses consist
primarily of salaries and related expenses for executive, finance and
administrative personnel, facilities expenses and other general corporate
expenses. General and administrative expenses were $1.9 million, $1.6 million
and $4.5 million in fiscal 1997, 1998 and 1999 or 55%, 9% and 3% of revenue,
respectively. The increase in absolute dollars was primarily due to an increase
in the allowance for doubtful accounts, the addition of personnel necessary to
support the increase in revenue and general corporate expenses consistent with
the increased scale of operations. We expect general and administrative
expenses to continue to increase in absolute dollars as we continue to build
the infrastructure necessary to support the growth of our business and operate
as a public company.

Interest income. Interest income is the net result of the interest earned on
the funds we keep on deposit in interest bearing money market and short-term
investment accounts less any interest expense incurred on our revolving bank
line of credit and capital lease obligations. Foundry had net interest income
of $122,000, $413,000 and $1.9 million in 1997, 1998 and 1999, respectively.
During 1998, we had cash balances in an interest bearing account resulting from
the proceeds of our financing in March 1998. During 1999, interest income
increased significantly due to higher cash balances resulting from the proceeds
from our initial public offering.

Income taxes. Foundry did not incur state or federal income taxes in fiscal
1997 and 1998 due to operating losses incurred during those periods. Foundry
recorded income tax expense for fiscal 1999 of $9.8 million. The provision for
1999 results in an effective tax rate of 30% which reflects the application of
the benefit from cumulative net operating loss carryforwards and accumulated
research credits. As of December 31, 1997 and 1998, Foundry recorded valuation
allowances for the total net deferred tax assets as a result of uncertainties
regarding realization of the assets based upon the limited operating history of
Foundry, the lack of profitability and the uncertainty of future profitability
during those periods.

Net income. Net income increased to $22.9 million for 1999 from a net loss
of $9.3 million for 1998. This increase was due to significantly higher
revenue.

Our operating results have varied significantly in the past and revenue and
operating results may vary significantly in the future due to a number of
factors, including: fluctuations in demand for our products and services,
particularly in Europe and Asia; the cancellation or rescheduling of
significant orders; our ability to develop, introduce, ship and support new
products and product enhancements and manage product transitions;

19


announcements and introductions of new products by our competitors and us; our
ability to build infrastructure to support increased growth; our ability to
achieve required cost reductions; our ability to obtain sufficient supplies of
limited-sourced components for our products; increases 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. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Risk Factors That May Affect Future Results and Market Price of
Stock--We may not meet quarterly financial expectations, which could cause our
stock price to decline" for a discussion of the risk of fluctuations in
operating results.

Liquidity and Capital Resources

On October 1, 1999, we completed our initial public offering in which we
raised gross proceeds of approximately $143.8 million from the sale of
11,500,000 shares of common stock. Prior to our initial public offering,
Foundry financed operations primarily through the private sales of common and
preferred stock for net proceeds of approximately $33.4 million and, to a
lesser extent, from a capital equipment lease line. At December 31, 1999,
Foundry had cash and cash equivalents of $120.4 million and short-term
investments of $39.8 million. Cash equivalents consisted of commercial paper
and cash deposited in money market accounts with original maturities of less
than three months. Short-term investments was comprised of corporate and U.S.
debt securities with original maturities greater than three months but less
than one year.

Cash provided by operating activities was $18.7 million for the year ended
December 31, 1999. Cash utilized in operating activities was $13.2 million in
1998 and $9.8 million in 1997. The cash utilized in 1998 and 1997 was due to
net losses, as well as working capital required to fund our growth in
operations, including accounts receivable and inventory.

Cash utilized in investing activities was $40.8 million for the year ended
December 31, 1999, $414,000 in 1998 and $526,000 in 1997. The cash utilized in
1998 and 1997 represented purchases of property and equipment, specifically
computers and electronic test equipment. In 1999 we used cash of $39.8 million
to purchase short-term investments and $1.0 million for property and equipment.

Financing activities provided $137.9 million in cash for the year ended
December 31, 1999, consisting primarily of proceeds from our initial public
offering, and to a lesser extent, from the exercise of stock options and
proceeds from the sale of preferred stock. In 1998, we generated $15.0 million
of cash and in 1997, we generated $9.6 million of cash, in each case primarily
from an equity financing and the exercise of stock options, offset by principal
repayments on capital lease obligations.

In December 1999 through March 2000, Foundry established subsidiaries in
foreign countries, including the United Kingdom, France, Canada, Netherlands,
Germany and Singapore, which function primarily as sales offices in those
locations. We have also established sales branch offices in Taiwan, Hong Kong,
Italy, Sweden and Ireland.

On September 28, 1999, we entered into a lease for approximately 71,000
square feet to serve as our new headquarters and manufacturing facility in San
Jose, California. Our lease commenced on February 1, 2000 and will expire on
January 31, 2006. The related rent expense is $131,000 per month.

As of December 31, 1999, we did not have any material commitments for
capital expenditures. However, we expect to incur capital expenditures as we
expand our operations in the near future. Although we do not have any current
plans or commitments to do so, from time to time, we may also consider the
acquisition of, or evaluate investments in, products and businesses
complementary to our business. Any acquisition or investment may require
additional capital. Although it is difficult for us to predict future liquidity
requirements with certainty, we believe that the net proceeds from our initial
public offering, together with our existing cash balances and anticipated funds
from operations, will satisfy our cash requirements for at least the next 12
months.

recently issued accounting standards.

Risk Factors That May Affect Future Results and Market Price of Stock

We have incurred losses in the past and may not be able to maintain
profitability in the future.

We incurred net losses of $2.0 million from inception through December 31,
1996, $9.0 million in 1997 and $9.4 million in 1998. We generated net income
of $22.9 million for the year ended December 31, 1999. As of December 31,
1999, we had retained earnings of $2.5 million. We expect to incur increased
costs and expenses related to:

. sales and marketing, including expansion of our direct sales operation
and distribution channels;

. product development;

. customer support;

. expansion of our corporate infrastructure; and

. facilities expansion.

Although we were profitable in each of the four quarters of fiscal 1999,
our ability to remain profitable depends on our ability to generate and
sustain substantially higher revenue while maintaining reasonable cost and
expense levels. We may not be able to sustain or increase profitability on a
quarterly or annual basis in the future.

We may not meet quarterly financial expectations, which could cause our stock
price to decline.

Our quarterly revenue and operating results are difficult to predict and
may fluctuate significantly from quarter to quarter. Delays in generating or
recognizing forecasted 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 for 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.
Therefore, we depend on obtaining orders in a quarter for shipment in that
quarter to achieve our revenue objectives. In addition, the failure to ship
products by the end of a quarter may negatively affect our operating results.
Our reseller agreements typically provide that the reseller may delay
scheduled delivery dates without penalty. Further, our customer purchase
orders and reseller agreements sometimes provide that the customer or reseller
may cancel orders within specified time frames without significant penalty.

We also plan to significantly increase our operating expenses to expand our
sales and marketing efforts, expand our customer support capabilities, finance
increased levels of research and development and build our operational and
administrative 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 shortfall in revenue relative to our expectations could
cause a significant decline in our quarterly operating results.

Intense competition in the market for network solutions could prevent us from
increasing revenue and sustaining profitability.

The market for network solutions is intensely competitive. In particular,
Cisco maintains a dominant position in this market and several of its products
compete directly with our products.

We also compete with other large public companies, such as 3Com and Nortel
Networks, as well as other smaller public and private companies. Many of our
current and potential competitors have longer operating

21


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. Additionally, we may face competition from unknown
companies and emerging technologies that may offer new LAN, MAN and LAN/WAN
solutions to enterprises and Internet service providers.

In order to remain competitive, we must, among other things, invest
significant resources in developing new products with superior performance at
lower prices than our competitors. We must also enhance our current products
and maintain customer satisfaction. If we fail to do so, our products may not
compete favorably with those of our competitors and our revenue and
profitability could suffer.

Our ability to increase our revenue depends on expanding our North American
direct sales operation and reseller distribution channels and continuing to
provide excellent customer support.

Our inability to effectively expand, train and retain our domestic sales and
support staff or establish our indirect distribution channels could harm our
ability to grow and increase revenue. Our expansion of our direct sales
operation may not be successfully completed and the cost of our expansion may
exceed the revenue generated. In addition, we have recently increased our sales
force in advance of sales, and if this increase does not result in an increase
in sales, our business may suffer.

If we fail to develop 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.

We need to increase our customer service and support staff to support new
and existing customers and resellers. The design and installation of networking
products can be complex and our customers, particularly our Internet service
provider customers, require a high level of sophisticated support and services.
Hiring highly trained 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.

If we fail to introduce new products with superior performance in a timely
manner, our ability to sustain and increase our revenue could suffer.

The current life cycle of our products is typically 18 to 24 months. To
remain competitive, we need to introduce new products in a timely manner that
offer substantially greater performance and support a greater number of users
per device, all at lower price points. We have experienced, and may in the
future experience, delays in developing and releasing new products and product
enhancements. This has led to, and may in the future lead to, delayed sales,
increased expenses and lower quarterly revenue than anticipated. During the
development of our products, we have also experienced delays in the prototyping
of our ASICs, which in turn has led to delays in product introductions. In
addition, 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. This could harm our
operating results by decreasing sales, increasing our inventory levels of older
products and exposing us to greater risk of product obsolescence.

We depend on large purchases from a few significant customers, and any loss,
cancellation or delay in purchases by these customers could cause a shortfall
in revenue.

To date, a limited number of customers and resellers have accounted for a
significant portion of our revenue. If any of these customers stop or delay
purchases, our revenue and profitability could suffer. In 1998, Mitsui & Co.
(U.S.A.) accounted for 21% of our revenue. In 1999, sales to Mitsui accounted
for less than 10% and sales to Hewlett-Packard and America Online accounted for
14% and 11% of our revenue, respectively.

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

. our reseller agreements generally do not require minimum purchases;

22


. our customers can stop purchasing and our resellers can stop marketing
our products at any time;

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

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

Because our expenses are based on our revenue forecasts, a substantial
reduction or delay in sales of our products to, or unexpected returns from
customers and resellers, or the loss of any significant customer or reseller
could harm our business. 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.

Our success depends upon sales to Internet service providers, whose
unpredictable demands, requirements and business models subject us to potential
adverse revenue fluctuations.

We have introduced products specifically targeted at the Internet service
provider market and currently have under development other products to address
their requirements. As a result, our success depends on increased sales to
Internet service providers. Although we expect these sales to increase, we
believe that there are a number of risks arising from doing business with
Internet service providers which may not arise in our relationships with our
other customers, including:

. Internet service providers demonstrate a low level of brand loyalty and
may switch to another supplier which provides superior performance;

. any failure of an Internet service provider's service to its customers,
particularly in the case of our largest Internet service provider
customer, America Online, that is correctly or incorrectly attributed to
our products could lead to substantial negative publicity and undermine
our efforts to increase our sales in both this market and other markets;

. we may lose Internet service provider customers if they fail due to the
highly competitive nature of their business or if they do not survive as
a result of mergers and acquisitions in the Internet service provider
industry; and

. if the Internet does not continue to expand as a widespread
communications medium and commercial marketplace, the growth of the
market for Internet infrastructure equipment may not continue and the
demand for our products could decline.

Due to these factors, we may not successfully increase our penetration of
the Internet service provider market or maintain our current level of sales in
this market.

Hewlett-Packard is a major customer and our sole OEM, and the termination of
our relationship with Hewlett-Packard could harm our business.

Hewlett-Packard, currently our sole OEM, accounted for 14% of our revenue in
1999, and we anticipate that it will continue to account for a significant
percentage of our revenue. In addition to providing revenue through sales of
our products to Hewlett-Packard, we believe that this relationship is important
to facilitate broad market acceptance of our products and enhance our sales,
marketing and distribution capabilities. Therefore, in addition to directly
affecting our revenue, the cancellation of our agreement with Hewlett-Packard
could harm our ability to market and sell our products to potential customers.

In addition, if we were to default under conditions specified in the
agreement, Hewlett-Packard could use our source code to develop and manufacture
competing products. This could harm our performance and ability to compete.


23


This agreement creates the potential that we and Hewlett-Packard may compete
for sales to the same customer. If this situation occurs, it could harm our
relationship with Hewlett-Packard and also harm our business.

We expect the average selling prices of our products to decrease which may
reduce gross margins or revenue.

Our industry has experienced rapid erosion of average product selling prices
due to a number of factors, particularly competitive 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 also anticipate that the average selling prices of our
products will decrease in response to competitive pressures, increased sales
discounts, new product introductions by our competitors or other factors.

If we are unable to hire additional qualified personnel as necessary or if we
lose key personnel, we may not be able to successfully manage our business or
achieve our objectives.

We believe our future success will depend in large part upon our ability to
identify, 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 engineers.
We may not succeed in identifying, attracting and retaining personnel. The loss
of the services of any of our key personnel, the inability to identify, 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 timely product
introductions. In addition, companies in the networking industry whose
employees accept positions with competitors frequently claim that competitors
have engaged in unfair hiring practices. We have received one claim like this
from another company and we may receive additional claims in the future. We
could incur substantial costs in defending ourselves against any such claims,
regardless of the merits of such claims.

Our success also depends to a significant degree upon the continued
contributions of our key management, engineering, sales and marketing, finance
and manufacturing personnel, many of whom would be difficult to replace. In
particular, we believe that our future success depends on Bobby R. Johnson,
Jr., President, Chief Executive Officer and Chairman of the Board, and H. Earl
Ferguson, Vice President, Hardware Engineering. We do not have employment
contracts or key person life insurance covering any of our personnel.

Our ability to increase our international sales is subject to a number of risks
we do not control.

Our success will depend, in part, on increasing international sales and
expanding our international operations. Our international sales primarily
depend on our resellers, including Boreal and Mitech in Europe, Mitsui in
Japan, Bell Canada in Canada, and Samsung in Korea. Although we expect
international revenue to increase as a percentage of our total revenue, the
failure of our resellers to sell our products internationally would limit our
ability to sustain and grow our revenue. In particular, our revenue from
international sales depends on Mitsui's ability to sell our products and on the
strength of the Japanese economy which has been weak in recent years.

There are a number of risks arising from our international business,
including:

. potential recessions in economies outside the United States, such as
Japan;

. longer accounts receivable collection cycles;

. difficulties in managing operations across disparate geographic areas;

. difficulties associated with enforcing agreements through foreign legal
systems;

. import or export licensing requirements;


24


. potential adverse tax consequences; and

. unexpected changes in regulatory requirements.

Generally, our international sales currently are denominated in U.S.
dollars. As a result, an increase in the value of the U.S. dollar relative to
foreign currencies could make our products less competitive on a price basis in
international markets. In the future, we may elect to invoice some of our
international customers in local currency, which could subject us to
fluctuations in exchange rates between the U.S. dollar and the local currency.

In January 1999, the new "Euro" currency was introduced in European
countries that are part of the European Monetary Union ("EMU"). During 2002,
all EMU countries are expected to completely replace their national currencies
with the Euro. Because a significant amount of uncertainty exists as to the
effect the Euro will have on the marketplace and because all of the final rules
and regulations have not yet been defined and finalized by the European
Commission regarding the Euro currency, we cannot determine the effect this
will have on our business.

Our reliance on single or limited sources for key components may inhibit our
ability to meet customer demand.

We currently purchase several key components used in our products from
single or limited sources and depend on supply from these sources to meet our
needs. Our principal suppliers of key components include Celestica, Texas
Instruments, Toshiba, Hewlett-Packard, Molex and Intel. We acquire these
components through purchase orders and have no long-term commitments regarding
supply or price from these suppliers. We may encounter shortages and delays in
obtaining components in the future which could impede our ability to meet
customer orders. Our principal limited-sourced components include:

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

. printed circuit boards; and

. microprocessors.

We depend on anticipated product orders to determine our material
requirements. Lead times for single- or limited-sourced materials and
components can be as long as six months, 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 either
excess or inadequate inventory of materials and components, which could
negatively affect our operating results and financial condition. From time to
time, we have experienced shortages in allocations of components, resulting in
delays in filling orders.

Our reliance on third-party manufacturing vendors to manufacture our products
may cause a delay in our ability to fill orders.

We currently subcontract substantially all of our manufacturing to two
companies, Celestica-Asia, located in San Jose, California, which assembles and
tests our printed circuit boards, and Hadco Corporation, located in Santa
Clara, California, which assembles and tests our backplane products. We do not
have long-term contracts with either of these manufacturers. We have
experienced delays in product shipments from our contract manufacturers, which
in turn delayed product shipments to our customers. We may in the future
experience similar delays or other problems, such as inferior quality and
insufficient quantity of product, any of which could harm our business and
operating results. We intend to regularly introduce new products and product
enhancements, which will require us to rapidly achieve volume production by
coordinating our efforts with those of our suppliers and contract
manufacturers. We attempt to increase our material purchases, contract
manufacturing capacity and internal test and quality functions to meet
anticipated demand. 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, or the ability to obtain raw materials, could cause a
delay in our ability to fulfill orders.

25


Due to the lengthy sales cycles of some of our products, the timing of our
revenue is difficult to predict and may cause us to miss our revenue
expectations.

Some of our products have a relatively high sales price, and often represent
a significant and strategic decision by an enterprise or Internet service
provider. As a result, the length of our sales cycle in these situations can be
as long as 12 months and 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 not meet our revenue expectations.

The timing of the adoption of industry standards may negatively impact
widespread market acceptance of our products.

Our success depends in part on both the adoption of industry standards for
new technologies in our market and our products' compliance with industry
standards. Many technological developments occur prior to the adoption of the
related industry standard. The absence of an industry standard related to a
specific technology may prevent market acceptance of products using the
technology. For example, we introduced Gigabit Ethernet products in May 1997,
over a year prior to the adoption of the industry standard for this technology.
We intend to develop products using other technological advancements, such as
10 Gigabit Ethernet, and may develop these products prior to the adoption of
industry standards related to these technologies. As a result, we may incur
significant expenses and losses due to lack of customer demand, unusable
purchased components for these products and the diversion of our engineers from
future product development efforts. Further, we may develop products that do
not comply with the eventual industry standard, which could hurt our ability to
sell these products. If the industry evolves to new standards, we may not be
able to successfully design and manufacture new products in a timely fashion
that meet these new standards. Even after industry standards are adopted, the
future success of our products depends upon widespread market acceptance of
their underlying technologies.

If our products contain undetected software or hardware errors, we could incur
significant unexpected expenses and lost sales and be subject to product
liability claims.

Our products are complex and may contain undetected defects or errors,
particularly when first introduced or as new enhancements and versions are
released. Despite our testing procedures, these defects and errors may be found
after commencement of commercial shipments. Any defects or errors in our
products discovered in the future or failures of our customers' networks,
whether caused by our products or another vendors' products could result in :

. negative customer reactions;

. product liability claims;

. negative publicity regarding us and our products;

. delays in or loss of market acceptance of our products;

. product returns;

. lost sales; and

. unexpected expenses to remedy errors.

Continued rapid growth will strain our operations and will require us to incur
costs to upgrade our infrastructure.

We have experienced rapid growth which has placed, and continues to place, a
significant strain on our resources. Our management team has limited experience
managing rapidly growing companies on a public or

26


private basis. As a result, we may make mistakes in operating our business,
such as inaccurately forecasting our sales, which may result in unanticipated
fluctuations in our operating results. To accommodate anticipated growth, we
must:

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

. hire, train and manage additional qualified personnel, including in the
near future, a significant number of new sales personnel; and

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

Our current or planned personnel systems, procedures and controls may not be
adequate to support our future operations. Any delay in the implementation of
or disruption in the transition to new or enhanced systems, procedures or
controls, could harm 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.

Failure to comply with domestic, foreign or international regulations could
prevent us from selling our products.

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
standards and regulations 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 revenue or maintaining profitability.

We may engage in future acquisitions that could result in the dilution of our
stockholders, cause us to incur substantial expenses and harm our business if
we cannot successfully integrate the acquired business, products, technologies
or personnel.

As part of our business strategy, we may review acquisition prospects that
would complement our existing business or enhance our technological
capabilities. Future acquisitions by us could result in large and immediate
write-offs, the incurrence of debt and contingent liabilities or amortization
expenses related to goodwill and other intangible assets, any of which could
negatively affect our results of operations. Furthermore, acquisitions involve
numerous risks and uncertainties, including:

. difficulties in the assimilation of products, operations, personnel and
technologies of the acquired companies;

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

. risks of entering geographic and business markets in which we have no or
limited prior experience; and

. potential loss of key employees of acquired organizations.

Although we do not currently have any agreements or plans with respect to
any material acquisitions, we may make acquisitions of complementary
businesses, products or technologies in the future. We may not be able to
successfully integrate any businesses, products, technologies or personnel that
might be acquired in the future, and our failure to do so could harm our
business.

We may need additional capital to fund our future operations which may not be
available to us on favorable terms when required or at all.

We believe that our existing working capital and cash from 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

27


insufficient, or if cash is used for acquisitions or other currently
unanticipated uses, we could be required to raise substantial additional
capital. Additional capital, if required, may not be available on acceptable
terms, or at all. If we are unable to obtain additional capital, we may be
required to reduce the scope of our planned product development and marketing
efforts, which could harm our business, financial condition and operating
results. 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 our existing stockholders. If additional funds are raised
through the issuance of debt securities, these securities would have rights,
preferences and privileges senior to holders of common stock and the terms of
debt securities could impose restrictions on our operations.

Problems arising from use of our products together with other vendors' products
could disrupt our business and harm our financial condition.

Our customers generally use our products together with products from other
vendors. As a result, when problems occur in the network, it may be difficult
to identify the source of the problem. These problems may cause us to incur
significant warranty and repair costs, divert the attention of our engineering
personnel from our product development efforts and cause significant customer
relation problems. If we fail to protect our intellectual property, our
business and ability to compete could suffer.

If we fail to protect our intellectual property, our business and ability to
compete could suffer.

Our success and ability to compete are substantially dependent upon our
internally developed technology and know-how. We do not own any patents nor do
we have any patent applications pending. We may not have taken actions that
adequately protect our intellectual property rights.

We provide software to customers under license agreements included in the
packaged software. These agreements are not negotiated with or signed by the
licensee, and thus may not be enforceable in some jurisdictions. Despite our
efforts to protect our proprietary rights through confidentiality and license
agreements, unauthorized parties may attempt to copy or otherwise obtain and
use our products or technology. These precautions may not prevent
misappropriation or infringement of our intellectual property. Monitoring
unauthorized use of our products is difficult and the steps we have taken may
not 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.

We may be subject to intellectual property infringement claims that are costly
to defend and could limit our ability to use certain technologies in the
future.

Our industry is characterized by the existence of a large number of patents
and frequent claims and related litigation regarding patent and other
intellectual property rights. In particular, leading companies in the
networking markets have extensive patent portfolios with respect to networking
technology, while we do not currently own any patents or have any patent
applications pending.

In July 1999, we received a letter from Resonate, Inc. alleging that our
ServerIron products infringe one of its patents. We have and intend to continue
to contest this claim vigorously. Although we have had no communication from
Resonate on this issue since December 1999, these kinds of disputes are subject
to inherent uncertainties and, therefore, we cannot assure you that we will
prevail in our objection to this claim, nor can we assure you that this dispute
will not result in litigation or that an adverse result or judgment will not
adversely affect our financial condition.

From time to time, other third parties, including leading companies, have
asserted against others and may assert against us exclusive patent, copyright,
trademark and other intellectual property rights to technologies and related
standards that are important to us. Third parties may assert claims or initiate
litigation against us or our manufacturers, suppliers or customers alleging
infringement of their proprietary rights with respect to our existing or future
products. Any of these claims, with or without merit, could be time-consuming,
result in

28


costly litigation and diversion of technical and management personnel, or
require us to develop non-infringing technology or enter into royalty or
license agreements. These royalty or license agreements, if required, may not
be available on acceptable terms, if at all. If there is a successful claim of
infringement or if we fail to develop non-infringing technology or license the
proprietary rights on a timely basis, our business could be harmed.

Our stock price may be extremely volatile.

Equity markets, particularly the market for technology companies, have
recently experienced significant price and volume fluctuations that are
unrelated to the operating performance of individual companies. These broad
market fluctuations may cause the market price of our common stock to decline.
In addition, the market price of our common stock is likely to be highly
volatile. In the past, securities class action litigation has often been
instituted against companies following periods of volatility in the market
price of their securities. This litigation could result in substantial costs
and a diversion of management's attention and resources.

Our executive officers and directors have substantial control over Foundry
which could delay or prevent a merger or other change in control of Foundry.

Our executive officers, directors and entities affiliated with them
beneficially own approximately 53% of our outstanding common stock as of
December 31, 1999. These stockholders, if acting together, would be able to
significantly influence the election of directors and all other matters
requiring approval by our stockholders. This concentration of voting control
could have the effect of delaying or preventing a merger or other change in
control, even if it would benefit our other stockholders.

Some provisions of our charter documents may have anti-takeover effects that
could discourage a change in control, even if an acquisition would be
beneficial to our stockholders.

Some provisions of our certificate of incorporation and bylaws could make it
more difficult for a third party to acquire us even if a change of control
would be beneficial to our stockholders.

Future sales of our common stock may depress our stock price.

All of the 11,500,000 shares sold in the initial public offering on
September 28, 1999 are freely tradeable. In addition, Deutsche Banc Alex.
Brown, the lead underwriter for our initial public offering authorized an early
lock-up release of approximately 5,100,000 shares of common stock subject to
the underwriters' lock-up restrictions. The released shares became available
for sale on February 10, 2000 without further restriction. The remaining shares
of common stock outstanding are subject to lock-up agreements that prohibit the
sale of shares for 180 days after September 27, 1999. Immediately after the 180
day lock-up period, the remaining outstanding shares of our common stock will
become available for sale, subject, in some cases, to the expiration of one-
year holding periods and/or the lapse of our repurchase option. Sales of a
substantial number of shares of common stock in the public market after the
expiration of the lock-up and holding periods could cause the market price of
our common stock to decline.

29


Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our exposure to market risk for changes in interest rates relates primarily
to our investment portfolio. We do not use derivative financial instruments in
our investment portfolio. We place our investments with high credit quality
issuers and, by policy, limit the amount of credit exposure to any one issuer
or fund. The portfolio includes only marketable securities with original
maturities of less than one year and with active secondary or resale markets to
ensure portfolio liquidity. We have no investments denominated in foreign
country currencies and therefore are not subject to foreign currency risk on
such investments. Due to the nature of our short-term investments, we have
concluded that there is no material market risk exposure. Therefore, no
quantitative tabular disclosures are required.

Currently, all of our sales and expenses are denominated in U.S. dollars,
with the exception of Canada, and, as a result, we have not experienced
significant foreign exchange gains and losses to date. While we do expect to
effect some transactions in foreign currencies in the next 12 months, we do not
anticipate that foreign exchange gains and losses will be significant. We have
not engaged in foreign currency hedging activities to date.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Foundry Networks, Inc.:

We have audited the accompanying balance sheets of Foundry Networks, Inc. (a
Delaware corporation) as of December 31, 1998 and 1999, and the related
statements of operations, redeemable convertible preferred stock and
stockholders' equity (deficit) and cash flows for each of the three years in
the period ended December 31, 1999. These financial statements and the schedule
referred to below are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Foundry Networks, Inc. as
of December 31, 1998 and 1999, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1999 in
conformity with accounting principles generally accepted in the United States.

Our audit was made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in Item 14(a)(2) is
presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audit of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

FOUNDRY NETWORKS, INC.

NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION OF THE COMPANY:

Foundry Networks, Inc. (the Company or Foundry) was incorporated in Delaware
on May 22, 1996 under the name Perennium Networks, Inc., and changed its name
to StarRidge Networks, Inc. on June 5, 1996 and to Foundry Networks, Inc. on
January 22, 1997. Foundry designs, develops, manufactures and markets a
comprehensive, end-to-end suite of high performance networking products for
enterprises, educational institutions, government agencies, web hosting
companies, Application Service Providers (ASPs), electronic banking and finance
service providers, and Internet service providers.

During 1997, Foundry commenced commercial shipment of its products and
emerged from the development stage. Although no longer in the development
stage, Foundry continues to be subject to the risks and challenges similar to
other companies in a comparable stage of development. These risks include, but
are not limited to, dependence on key individuals, dependence on key suppliers
of integral components, successful development and marketing of products, the
ability to obtain adequate financing to support growth and competition from
substitute products and larger companies with greater financial, technical,
management and marketing resources.

2. SIGNIFICANT ACCOUNTING POLICIES:

Use of Estimates in Preparation of Financial Statements

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.

Stock Splits

In July 1999, Foundry's board of directors approved a three for two stock
split of its outstanding common and preferred stock. In November 1999,
Foundry's board of directors approved a two for one stock split of its
outstanding common stock. The stock began public trading on a split-adjusted
basis on January 10, 2000. All share and per share information included in
these financial statements have been retroactively adjusted to reflect the
stock splits.

Cash, Cash Equivalents and Short-Term Investments

Foundry considers all highly liquid investments with original maturities of
three months or less to be cash equivalents. Cash and cash equivalents consist
of commercial paper and cash deposited in checking and money market accounts.

Foundry accounts for its investments under the provision of Statement of
Financial Accounting Standards No. 115 (SFAS 115), "Accounting for Certain
Investments in Debt and Equity Securities." Investments in highly liquid
financial instruments with original maturities greater than three months but
less than one year are classified as short-term investments. As of December 31,
1999, Foundry's short-term investments, which were stated at amortized cost and
classified as held-to-maturity, consisted of corporate and U.S. debt
securities.

Inventories

Inventories are stated on a first-in, first-out basis at the lower of cost
or market, and include purchased parts, labor and manufacturing overhead.
Inventories consist of the following (in thousands):

Purchased parts.............................................. $ 5,302 $12,176
Work-in-process.............................................. 1,281 2,700

------- -------
$ 7,201 $16,743
======= =======


Provision for excess and obsolete inventory in the amounts of $106,000, $1.0
million and $3.8 million were recorded for the years ended December 31, 1997,
1998 and 1999, respectively. Approximately $779,000 and $3.4 million of work-
in-process inventory was consigned at contract manufacturers' sites as of
December 31, 1998 and 1999.

Concentrations

Financial instruments that potentially subject Foundry to a concentration of
credit risk principally consist of cash equivalents, short-term investments and
accounts receivable. Foundry invests only in high credit quality issuers and,
by policy, limits the amount of credit exposure to any one issuer or fund.
Foundry performs ongoing credit evaluations of its customers and generally does
not require collateral. To date, credit losses have been immaterial and within
management's expectations. During the year ended December 31, 1999, Foundry

38


FOUNDRY NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

provided approximately $1.3 million to its allowance for doubtful accounts. Ten
customers accounted for 58% and 62% of trade receivables as of December 31,
1998 and 1999, respectively.

Foundry purchases several key components used in the manufacture of products
from single or limited sources and depends on supply from these sources to meet
its needs. In addition, Foundry depends on contract manufacturers for major
portions of the manufacturing requirements. The inability of the suppliers or
manufacturers to fulfill the production requirements of Foundry could
negatively impact future results.

Property and Equipment

Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over estimated useful lives as follows:



Computers and related equipment...................................... 2 years
Furniture and fixtures............................................... 3 years


Revenue Recognition

Foundry generally recognizes product revenue upon shipment to customers.
Revenue from customer support services is deferred and recognized on a
straight-line basis over the contractual period. At shipment date, Foundry
establishes an accrual for estimated warranty expenses associated with sales.
Foundry's warranty period extends 12 months from the date of sale. In 1999,
Foundry recorded a provision for sales returns equal to $1.2 million which has
been netted with revenue in the statements of operations. This provision is
based on our historical returns. The contracts with resellers do not provide
for rights of return and the contract with the original equipment manufacturer
also does not provide for rights of return except in the event products do not
meet specifications or there has been an epidemic failure, as defined in the
agreement.

During 1997, 1998 and 1999, approximately 100%, 99% and 98%, respectively,
of Foundry's total revenue was derived from product sales. The percentages of
revenue to significant customers were as follows:



Year Ended December 31,
----------------------------
1997 1998 1999
------- -------- ---------

Customer A..................................... 49% 21% --
Customer B..................................... 14% -- 11%
Customer C..................................... -- -- 14%

Sales in significant markets were as follows (in thousands):


Year Ended December 31,
----------------------------
1997 1998 1999
------- -------- ---------

United States.................................. $ 1,649 $ 11,816 $ 113,958
Japan.......................................... 1,647 3,657 9,094


Foundry sells to various countries in North America, Europe, Asia, South
America and Australia. Sales to individual countries other than disclosed above
within these continents represent less than 10% of total revenue.

Software Development Costs

Foundry accounts for internally generated software development costs in
accordance with Statement of Financial Accounting Standards (SFAS) No. 86,
"Accounting for the Costs of Computer Software to be Sold,

39


FOUNDRY NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Leased or Otherwise Marketed." Capitalization of eligible product development
costs begins upon the establishment of technological feasibility, which Foundry
has defined as completion of a working model. Internally generated costs which
were eligible for capitalization, after consideration of factors such as
realizable value, were not material for the years ended December 31, 1997, 1998
and 1999 and, accordingly, all software development costs have been charged to
research and development expense in the accompanying statements of operations.

Computation of Per Share Amounts

Basic net income (loss) per common share and diluted net income (loss) per
common share are presented in conformity with Statement of Financial Accounting
Standards (SFAS) No. 128, "Earnings Per Share" for all periods presented.
Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
98, common stock and convertible preferred stock issued or granted for nominal
consideration prior to the anticipated effective date of the initial public
offering must be included in the calculation of basic and diluted net income
(loss) per common share as if such stock had been outstanding for all periods
presented. To date, Foundry has not had any issuances or grants for nominal
consideration.

In accordance with SFAS No. 128, basic net income (loss) per common share
has been calculated using the weighted-average number of shares of common stock
outstanding during the period, less shares subject to repurchase. For the years
ended December 31, 1997 and 1998 Foundry has excluded all convertible preferred
stock, outstanding stock options and shares subject to repurchase from the
calculation of diluted net loss per common share because all such securities
are anti-dilutive for those periods. The total number of shares excluded from
the calculations of diluted net loss per common share were 33,227,488 and
52,002,570 for the years ended December 31, 1997 and 1998. For the year ended
December 31, 1999, diluted net income per common share has been calculated
assuming the conversion of all dilutive potential common stock using the
treasury stock method. Pro forma basic net income (loss) per common share has
been calculated assuming the conversion of the redeemable convertible preferred
stock using the if-converted method into an equivalent number of common shares
as if the shares had been converted on the dates of issuance.

Stock-Based Compensation

In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, "Accounting for Stock-Based Compensation" (SFAS No. 123). This accounting
standard permits the use of either a fair value based method or the method
defined in Accounting Principles Board Opinion 25, "Accounting for Stock Issued
to Employees" (APB Opinion 25) to account for stock-based compensation
arrangements. Companies that elect to employ the valuation method provided in
APB Opinion 25 are required to disclose the pro forma net income (loss) that
would have resulted from the use of the fair value based method. Foundry has
elected to determine the value of stock-based compensation arrangements under
the provisions of APB Opinion 25, and accordingly, the pro forma disclosures
required under SFAS No. 123 have been included in Note 8.

Recent Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income," which establishes standards for reporting and
presentation of comprehensive income. SFAS No. 130 was adopted by Foundry in
1998. This standard defines comprehensive income as the changes in equity of an
enterprise except those resulting from stockholder transactions. Comprehensive
income (loss) for the years ended December 31, 1997, 1998 and 1999 equaled net
income (loss).

In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." SFAS No.
131 was adopted by Foundry in 1997. SFAS No. 131 establishes standards for
disclosures about operating segments, products and services, geographic areas
and major customers. Foundry is organized and operates as one operating
segment, the design, development, manufacturing and marketing of high
performance Gigabit Ethernet switches, switching routers, server load balancing
and transparent caching switches.

In March 1998, the AICPA issued Statement of Position No. 98-1, "Accounting
for the Costs of Computer Software Developed or Obtained for Internal Use" (SOP
No. 98-1). SOP No. 98-1 requires entities to capitalize certain costs related
to internal-use software once certain criteria have been met. SOP No. 98-1 was
adopted by Foundry in 1998. The adoption of SOP No. 98-1 did not have a
material impact on Foundry's financial position or results of operations.

In June 1998, the Financial Accounting Standards Board SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133
establishes accounting and reporting standards requiring that every derivative
instrument be recorded in the balance sheet as either an asset or liability
measured at its fair value. SFAS No. 133, as recently amended, is effective for
fiscal years beginning after June 15, 2000. Management believes the adoption of
SFAS No. 133 will not have a material effect on Foundry's financial position or
results of operations.

In December 1998, the AICPA issued SOP No. 98-9, "Modification of SOP No.
97-2, Software Revenue Recognition, With Respect to Certain Transactions." SOP
No. 98-9 amends SOP No. 97-2 and SOP No. 98-4 by extending the deferral of the
application of certain provisions of SOP No. 97-2 amended by SOP No. 98-4
through fiscal years beginning on or before March 15, 1999. All other
provisions of SOP No. 98-9 are effective for transactions entered into in
fiscal years beginning after March 15, 1999. Foundry has not had significant
software sales to date and management does not expect the adoption of SOP No.
98-9 to have a significant effect on the financial position or results of
operations.

In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 (SAB 101). SAB 101 summarizes certain areas of the
Staff's views in applying generally accepted


42


FOUNDRY NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

accounting principles to revenue recognition in financial statements. Foundry
believes that its current revenue recognition principles comply with SAB 101.

3. COMMITMENTS AND CONTINGENCIES:

In September 1999, Foundry entered into a noncancellable operating lease for
approximately 71,000 square feet to serve as its new headquarters and
manufacturing facility in San Jose, California. The lease commenced on February
1, 2000 and will expire on January 31, 2006. Straight-line rent expense for
this new building is $131,000 per month. Foundry has entered into other
noncancellable operating leases for its sales offices in California, Texas,
Virginia, Canada and the United Kingdom which have expiration dates ranging
from 2000-2006. Rent expense was approximately $245,000, $263,000 and $409,000,
respectively, for the years ended December 31, 1997, 1998 and 1999.

Future payments on operating leases as of December 31, 1999 were as follows
(in thousands):

2004............................................................ 1,878
2005 and thereafter............................................. 2,231
-------
Total lease payments............................................ $11,178
=======


Foundry is subject to various claims which arise in the normal course of
business. Although the amount of any liability with respect to such litigation
cannot be determined, in the opinion of management, the ultimate disposition of
these claims will not have a material adverse effect on Foundry's financial
position or results of operations.

During 1997, Foundry incurred costs and expenses in the amount of $750,000
related to the settlement of a lawsuit, which is reflected in the 1997
statements of operations under general and administrative expenses. In July
1999, Foundry received a letter from an unrelated company alleging that its
ServerIron products infringed one of the other company's patents. Foundry
intends to contest this claim and the potential liability and outcome related
to this claim cannot be determined at this time.

4. BANK LINE OF CREDIT:

In February 1999, Foundry entered into a revolving line of credit agreement
(the Agreement) with a bank which expired on February 18, 2000. The Agreement
provided for borrowings up to $10,000,000 of eligible accounts receivable at
the bank's prime rate. Foundry had no borrowings outstanding under the line of
credit as of December 31, 1999.

5. INCOME TAXES:

Foundry accounts for income taxes pursuant to SFAS No. 109, "Accounting for
Income Taxes." SFAS No. 109 provides for an asset and liability approach to
accounting for income taxes under which deferred income taxes are provided
based upon enacted tax laws and rates applicable to the periods in which taxes

43


FOUNDRY NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

become payable. As of December 31, 1998, a valuation allowance was recorded for
the total net deferred tax assets as a result of uncertainties regarding
realization of the assets based upon the limited operating history of Foundry,
the lack of profitability to date and the uncertainty of future profitability
at that time. As of December 31, 1998 and 1999, components of the net deferred
income tax assets were as follows (in thousands):



December 31,

-------
Total provision..................................................... $ 9,750
=======


Foundry had no provision for income taxes during the years ended December
31, 1997 and 1998 due to net operating losses incurred during those periods.
The income tax provision for the year ended December 31, 1999 differs from the
statutory rate primarily due to the application of the benefit from the
cumulative net operating loss carryforwards of approximately $15.3 million and
accumulated federal and state research credits of $1.3 million and $1.1
million, respectively. The benefit was offset by the amortization of deferred
compensation expense recorded for financial reporting purposes but not for tax
purposes.

The actual provision for income taxes differs from the statutory U.S.
federal income tax rate as follows for fiscal 1999 (in thousands):



Provision at U.S. statutory rate of 35%............................. $11,418
State income taxes, net of federal benefit.......................... 1,709

6. INITIAL PUBLIC OFFERING:

On September 28, 1999, Foundry commenced trading of its common stock on the
Nasdaq National Market in an initial public offering with the sale of
11,500,000 shares of common stock (including the exercise of the over-allotment
option of 1,500,000 shares) at $12.50 per share and realized net proceeds of
$131.8 million. Concurrent with the closing of the offering on October 1, 1999,
45,349,770 shares of redeemable convertible preferred stock were converted into
an equivalent number of shares of common stock.

7. STOCKHOLDERS' EQUITY (DEFICIT):

Redeemable Convertible Preferred Stock

In June 1996, Foundry issued 17,250,000 shares of Series A redeemable
convertible preferred stock (Series A) at $0.33 per share. In June to December
1997, Foundry issued 12,260,850 shares of Series B redeemable convertible
preferred stock (Series B) at $0.77 per share. In March 1998, Foundry issued
15,463,920 shares of Series C redeemable convertible preferred stock (Series C)
at $0.97 per share. In June 1999, Foundry issued 375,000 shares of Series C at
$2.67 per share to a family trust, of which an appointed director of Foundry is
a trustee.

On October 1, 1999, Foundry completed its initial public offering of
11,500,000 shares of common stock at $12.50 per share. In connection with the
initial public offering, all of the then outstanding shares of preferred stock,
totaling 45,349,770, automatically converted into an equivalent number of
shares of common stock.

Preferred Stock

Foundry is authorized to issue up to 5,000,000 shares of preferred stock,
each with a par value of $0.0001 per share. The preferred stock may be issued
from time to time in one or more series. The board of directors is authorized
to determine the rights, preferences, privileges and restrictions on these
shares. As of December 31, 1999, no shares of preferred stock had been issued.

Common Stock

Foundry is authorized to issue up to 200,000,000 shares of common stock,
each with a par value of $0.0001 per share. Foundry had 55,831,968 and
114,189,450 shares of common stock issued and outstanding at December 31, 1998
and 1999, respectively. Included in such outstanding shares are 32,940,000
shares issued to Foundry's founders in 1996 (the Founders Shares). The Founders
Shares were issued subject to a repurchase option by Foundry. The Founders
Shares vest out of the repurchase option 25 percent upon issuance, with the
balance vesting ratably each month for the 48 months after issuance. At
December 31, 1999, approximately 2,860,469 of the Founders Shares are unvested.
As further defined in the respective stock purchase agreements, (i) any
unvested Founders Shares immediately vest prior to the sale or merger of
Foundry to certain non-controlled parties and (ii) Foundry has certain rights
of first refusal to repurchase the Founders Shares until such time that
Foundry's common shares trade on a public market. In June 1999, the Company
repurchased 1,200,000 unvested shares from a founder at $0.003 per share. The
repurchase was recorded as treasury stock on the accompanying balance sheet as
of December 31, 1999.

In January 1999, Foundry granted 1,059,000 nonstatutory stock options to
certain key employees outside of the 1996 Stock Plan at an exercise price of
$0.83 per share. The options vest over a four-year period and expire in January
2009. During fiscal 1999, 150,000 shares were exercised and 68,250 shares were
cancelled. The weighted average remaining contractual life of the options was
9.0 years as of December 31, 1999.

Preferred Stock Warrants

During October 1996, in connection with a sales and leaseback arrangement,
Foundry issued warrants to a lessor to purchase 90,000 shares of Series A at
$0.33 per share, which converted to warrants to purchase common stock upon the
completion of the Company's initial public offering on October 1, 1999. At the
date of issuance, the value of the warrants were deemed immaterial and,
accordingly, no expense was recorded. In November 1999, the warrants were
exercised in a net exercise settlement.

1996 Stock Plan

Under Foundry's 1996 Stock Plan (the Plan), the board of directors
authorized the issuance of 42,810,000 shares to employees and consultants as
of December 31, 1999. Nonstatutory options granted under the Plan must be
issued at a price equal to at least 85% of the fair market value of Foundry's
common stock at the date of grant if granted to others. Incentive stock
options granted under the Plan must be issued at a price at least equal to the
fair market value of Foundry's common stock at the date of grant. All options
may be exercised at any time within ten years of the date of grant or within
one month of termination of employment, or such shorter time as may be
provided in the stock option agreement, and vest over a vesting schedule
determined by the board of directors, generally four years.

All of these options are exercisable as of December 31, 1999 because option
holders have the right to exercise their options early subject to the right of
the Company to repurchase unvested shares at the original purchase price. The
number of shares vested and exercisable under the Plan as of December 31, 1997,
1998 and 1999 is as follows:



Weighted
Number of Average
Options Exercise Price
--------- --------------

Vested and exercisable at December 31, 1997......... 600,312 $0.04
Vested and exercisable at December 31, 1998......... 901,206 $0.07
Vested and exercisable at December 31, 1999......... 2,328,268 $0.35


Foundry accounts for stock options issued to employees under APB Opinion No.
25 whereby the difference between the exercise price and the fair value at the
date of grant is recognized as compensation expense. Had compensation expense
been determined consistent with SFAS No. 123, net income would have decreased
and losses would have increased to the following pro forma amounts (in
thousands except per share data):



Year Ended December 31,
-------------------------
1997 1998 1999
------- ------- -------

Net income (loss) as reported..................... $(9,007) $(9,352) $22,872
Pro forma net income (loss)....................... (9,060) (9,483) 19,448
Basic net income (loss) per share as reported..... (0.67) (0.35) 0.42
Pro forma net income (loss) per share............. (0.67) (0.35) 0.35
Diluted net income (loss) per share as reported... (0.67) (0.35) 0.20
Pro forma diluted net income (loss) per share..... (0.67) (0.35) 0.17


The weighted average fair value of options granted during 1997, 1998 and
1999 was $0.01, $0.04 and $2.70 respectively. Pursuant to the provisions of
SFAS No. 123, the compensation cost associated with options granted in 1997,
1998 and 1999 was estimated on the grant date using the Black-Scholes model and
the following assumptions:



1997 1998 1999
------- ------- -------

Average risk free interest rate................... 6.49% 5.98% 5.56%
Average expected life of option................... 4 years 4 years 4 years
Dividend yield.................................... 0% 0% 0%
Volatility of common stock........................ .01% .01% 55.0%


In connection with the issuance of certain stock options to employees,
Foundry has recorded deferred stock compensation in the aggregate amount of
approximately $4.7 million and $17.3 million in 1998 and 1999, respectively,
representing the difference between the deemed fair value of Foundry's common
stock for accounting purposes and the exercise price of stock options at the
date of grant. Foundry is amortizing the deferred stock compensation expense
over the vesting period, generally four years. For the years ended December
31,1998 and 1999, amortization expense was approximately $727,000 and $9.5
million, respectively. At December 31, 1999, the remaining deferred stock
compensation of approximately $11.8 million will be amortized as follows: $6.5
million during fiscal 2000, $3.4 million during fiscal 2001, $1.6 million
during fiscal 2002, $300,000 during fiscal 2003. The amortization expense
relates to options granted to employees in all operating expense categories.
The amortization of deferred stock compensation has not been separately
allocated to these categories. The amount of deferred stock compensation
expense to be recorded in future periods could decrease if options for which
accrued but unvested compensation has been recorded are forfeited.

1999 Directors' Stock Option Plan

the board of directors in July 1999. A total of 1,350,000 shares of common
stock has been reserved for issuance under the Directors' Plan.

Under the Directors' Plan, each non-employee director who becomes a non-

automatic initial grant of an option to purchase 225,000 shares of common stock
upon appointment or election and annual grants to purchase 60,000 shares of
common stock. Options granted under the plan will vest at the rate of 1/4th of
the total number of shares subject to the options twelve months after the date
of grant and 1/48th of the total number of shares subject to the options each
month thereafter. The exercise price of all stock options granted under the
1999 Directors' Stock Option Plan shall be equal to the fair market value of a
share of common stock on the date of grant of the option. Options granted under
this plan have a term of ten years. As of December 31, 1999, no options were
granted under the Directors' Plan.

1999 Employee Stock Purchase Plan

The 1999 Employee Stock Purchase Plan (the Purchase Plan) was adopted by the
board of directors in July 1999. A total of 1,500,000 shares of common stock

reserved for issuance under the Purchase Plan will be increased on the first
day of each fiscal year from 2000 through 2009 by the lesser of:

. 1,500,000 shares;

. 2% of our outstanding common stock on the last day of the immediately
preceding fiscal year; or

. the number of shares determined by the board of directors.

The Purchase Plan enables eligible employees to purchase common stock
through payroll deductions, which in any event may not exceed 20% of an
employee's compensation, at a price equal to the lower of 85% of the fair
market value of the Company's common stock at the beginning of each offering
period or at the end of each purchase period. As of December 31, 1999, no
shares had been purchased under the Purchase Plan.

8. 401(K) PLAN:

Foundry provides a tax-qualified employee savings and retirement plan which
entitles eligible employees to make tax-deferred contributions. Under the
401(k) Plan, employees may elect to reduce their current annual compensation up
to the lesser of 20% or the statutorily prescribed limit, which is $10,000 in
calendar year 1999. Foundry may, at its discretion, make matching or
discretionary contributions to the 401(k) Plan. Foundry has made no matching or
discretionary contributions to date.

9. SUBSEQUENT EVENTS (unaudited):

On January 31, 2000, 131,212 shares were purchased for Foundry employees
