                            RIVERSTONE NETWORKS,INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)

Note (1) Business Operations

On February 10, 2000, Cabletron Systems, Inc. ("Cabletron") announced its plan
to create an independent publicly-traded company, Riverstone Networks, Inc.
("Riverstone" or the "Company"), comprised of Cabletron's Internet
infrastructure solutions business for Internet service providers and other
service providers. After the completion of Riverstone's initial public offering
on February 22, 2001, Cabletron owned 92,088,235 shares of common stock,
representing approximately 86% of Riverstone's outstanding common stock.

On June 3, 2000, Cabletron, Riverstone and certain related parties entered into
a Transformation Agreement, and Cabletron and Riverstone entered into a
Contribution Agreement. In accordance with the Transformation Agreement,
Cabletron transferred to Riverstone the Cabletron-owned assets and liabilities
which related to the Riverstone business on August 28, 2000 (the "Contribution
Date"). Zeitnet was also contributed to and then merged into Riverstone. The
accompanying financial statements for the three and six months ended September
2, 2000 reflect the historical basis of the Cabletron-owned assets and
liabilities, which were transferred at the Contribution Date.

On July 24, 2001, Riverstone issued 7,117,757 shares of common stock to
Cabletron in exchange for approximately $122 million in cash and certain
strategic investments, with an historic cost of approximately $13 million. On
August 6, 2001, Cabletron distributed all of its shares of Riverstone's common
stock to its stockholders and Riverstone ceased to be a subsidiary of Cabletron.
In connection with Cabletron's distribution of the Company's common stock to its
stockholders, Riverstone was required to issue warrants to certain of
Cabletron's investors to purchase 230,364 shares of its common stock.
Additionally, Riverstone was obligated to grant supplemental options under its
2000 Equity Incentive Plan to acquire 3,146,272 shares of its common stock to
those persons who held compensatory Cabletron stock options.

On the distribution date, Cabletron merged its subsidiary Enterasys Networks,
Inc. into itself and renamed itself Enterasys Networks, Inc. The terms Cabletron
and Enterasys included hereafter refer to Enterasys Networks, Inc. (formerly
known as Cabletron Systems, Inc.) and Old Enterasys refers to the Enterasys
Networks, Inc. that existed as a subsidiary of Cabletron prior to its merger
into Cabletron.

Note (2) Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The unaudited condensed consolidated financial statements have been prepared by
Riverstone pursuant to the rules and regulations of the Securities and Exchange
Commission and include the accounts of Riverstone and its wholly-owned
subsidiaries. Certain information and footnote disclosures, normally included in
financial statements prepared in accordance with generally accepted accounting
principles, have been condensed or omitted pursuant to such rules and
regulations. While in the opinion of the Company, the unaudited financial
statements reflect all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the financial position at
September 1, 2001 and the operating results and cash flows for the six months
ended September 2, 2000 and September 1, 2001, these financial statements and
notes should be read in conjunction with the Company's audited consolidated
financial statements and notes for the year ended March 3, 2001 included in the
Company's Annual Report on Form 10-K filed with the Securities and Exchange
Commission. The condensed consolidated balance sheet at March 3, 2001 has been
derived from audited financial statements as of that date.

The consolidated financial statements as of September 2, 2000 have been prepared
using Cabletron's historical basis in the assets and liabilities and the
historical results of operations of Riverstone.

The consolidated financial information for the period prior to the Cabletron
share distribution (August 6, 2001) includes allocations of certain Cabletron
expenses, including centralized legal, accounting, treasury, real estate,
information technology, distribution, customer service, advertising, sales,
marketing, engineering and other Cabletron corporate services and infrastructure
costs. All of the allocations and estimates in the financial statements are
based upon assumptions that the Company's and Cabletron's management believed to
be reasonable reflections of the cost of services provided or benefit received
by Riverstone. However, these financial statements do not necessarily indicate
the financial position or results of operations that would have occurred if the
Company were a stand-alone entity during the applicable periods.

Cash, Cash Equivalents and Investments

The Company considers all highly liquid investments with original maturity dates
of 90 days or less at the date of acquisition to be cash equivalents. Cash
equivalents and investments consist of money market funds, commercial paper,
government securities, and marketable debt securities. To date all investments
have been classified as available-for-sale and are carried at fair value. Any
unrealized gains or losses are reported as a separate component of stockholders'
equity when significant. Premiums and discounts are amortized over the period
from acquisition to maturity and are included in investment income, along with
interest and dividends. The Company has invested in equity and debt of non
publicly-traded companies. These investments have been made in order to
establish relationships with companies in markets that the Company believes are
consistent with its long-term strategic direction. Riverstone holds less than
20% of the equity of each of these companies and does not have the ability to
exercise significant influence over their operations. Accordingly, these
investments are accounted for using the cost method. These investments of
approximately $25.5 million, including those transferred from Cabletron in July
2001, are included in other long-term investments in the accompanying condensed
consolidated balance sheet as of September 1, 2001. During the three months
ended September 1, 2001, sales to affiliated investee companies represented
approximately 19% of net revenues.


Inventories

Inventories are stated at the lower of cost or market. Costs are determined at
standard cost, which approximates the first-in, first-out (FIFO) method.

Inventories consist of (in thousands):

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

Revenue Recognition

The Company generally recognizes revenue upon shipment of products provided
there are no uncertainties regarding customer acceptance, persuasive evidence of
an arrangement exists, the sales price is fixed and determinable and
collectibility is deemed probable. If uncertainties exist, revenue is recognized
when such uncertainties are resolved. Revenues from service and maintenance
contracts are deferred and recognized ratably over the period the services are
performed, typically twelve months or less. When the Company provides a
combination of products and services to a customer, revenue is allocated based
on the fair values. Estimated costs to repair or replace products that may be
returned under warranty are accrued at the time of shipment. The Company's
warranty period typically extends twelve months from the date of shipment. Sales
to customers in which the Company receives an equity instrument as consideration
are recorded at the estimated fair value of the instrument received as
determined by an independent appraisal or a recent cash equity transaction
received by the customer from an unrelated third party. Deferred revenue is
recognized into income when the above criteria have been met.

Lease Financing. The Company occasionally enters into transactions in which
customers receive financing for the purchase of Company equipment from third
party leasing organizations, who in turn remit payment to the Company. In
certain transactions, the Company has guaranteed a portion of the customer's
lease payments to be made to the lessor. When the Company provides a financing
guarantee, it records revenue at the time of shipment, subject to a sales
reserve. The Company bases the amount of the reserve on a percentage of the
guaranteed lease payments, based on specific customer analysis, supplemented
with industry experience. Accordingly, the Company has deferred revenue subject
to this reserve that will be recognized by the end of the respective lease terms
if all lease payments are made by end users.

Customer Concentration

During the quarter ended September 1, 2001, one reseller customer accounted for
more than 10% of net revenues, compared with one customer accounting for more
than 10% of net revenues in the quarter ended September 2, 2000.

Segment Reporting

Financial Accounting Standards Board Statement No.131, Disclosures about
Segments of an Enterprise and Related Information ("SFAS 131") establishes
standards for reporting information regarding operating segments in annual
financial statements and

                                       7


requires selected information for those segments to be presented in interim
financial reports. SFAS 131 also establishes standards for related disclosures
about products and services and geographic areas. Operating segments are
identified as components of an enterprise about which separate discrete
financial information is available for evaluation by the chief operating
decision maker in making decisions how to allocate resources and assess
performance. To date, the chief operating decision maker has viewed the
Company's operations as principally one segment, an Internet infrastructure
solutions business for Internet service providers and other service providers.
Revenues based on product shipment destination from unaffiliated customers by
geographic region are as follows:

Historical Net Loss Per Share

Basic net income or loss per common share and diluted net income or loss per
common share are presented in conformity with Statement of Financial Accounting
Standards No.128, Earnings Per Share ("SFAS 128") for all periods presented. In
accordance with SFAS 128, basic net income or loss per common share has been
calculated using the weighted-average number of shares of common stock
outstanding during the period. For the three months ended September 1, 2001,
diluted net income per common share has been calculated assuming the conversion
of all dilutive potential common stock.

For the three months ended September 2, 2000 and six months ended September 1,
2001 and September 2, 2000, Riverstone has excluded all outstanding stock
options as well as stock purchase rights held by private investors from the
calculation of diluted net loss per common share because such securities are
anti-dilutive for those periods.

Pro Forma Basic and Diluted Net Loss per Share

The Series A Convertible Preferred Stock automatically converted into common
stock at the 1:1 conversion rate upon the closing of the Company's initial
public offering. The pro forma basic and diluted net loss per share information
included in the accompanying statements of operations for the three months and
six months ended September 2, 2000 reflects the impact on pro forma basic and
diluted net loss per share of such conversion as of the beginning of the period
using the if-converted method.

The following tables present the calculation of historical basic and diluted net
income/(loss) per share, and pro forma basic and diluted net loss per share (in
thousands, except share and per share amounts):

Recently Issued Accounting Standards

In July 2001, the Financial Accounting Standards Board ("FASB") issued SFAS No.
141, "Business Combinations" and SFAS No. 142, "Goodwill and Other Intangible
Assets". SFAS No. 141 requires that the purchase method of accounting be used
for all business combinations initiated after June 30, 2001 as well as all
purchase method business combinations completed after June 30, 2001. SFAS No.
141 eliminates the use of the pooling-of-interest method of accounting for
business combinations. SFAS No. 142 is effective for all fiscal years beginning
after December 15, 2001, and changes the accounting for goodwill from an
amortization method approach to an impairment-only approach.

The Company is required to adopt the provisions of SFAS No. 141 immediately and
SFAS No. 142 effective March 3, 2002.  The adoption of SFAS No. 141 did not have
a material impact on the Company's financial position or results of operations.
The Company is currently reviewing and assessing the impact of SFAS No. 142 on
its financial position and results of operations.

In June 2001, the FASB issued Statement No. 143, "Accounting for Asset
Retirement Obligations," which addresses financial accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset retirement costs.  The standard applies to legal obligations
associated with the retirement of long-lived assets that result from the
acquisition, construction, development and (or) normal use of the asset.

SFAS No. 143 requires that the fair value of a liability for an asset retirement
obligation be recognized in the period in which it is incurred if a reasonable
estimate of fair value can be made.  The fair value of the liability is added to
the carrying amount of the associated asset and this additional carrying amount
is depreciated over the life of the asset.  The liability is accreted at the end
of each period through charges to operating expense.  If the obligation is
settled for other than the carrying amount of the liability, the Company will
recognize a gain or loss on settlement.

The Company is required to adopt the provisions of SFAS No. 143 effective for
the fiscal year starting March 2, 2003. To accomplish this, the Company must
identify all legal obligations for asset retirement obligations, if any, and
determine the fair value of these obligations on the date of adoption. The
determination of fair value is complex and will require the Company to gather
market information and develop cash flow models. Additionally, the Company will
be required to develop processes to track and

                                       9


monitor these obligations. The Company is currently reviewing and assessing the
impact of SFAS No. 143 on its financial position and results of operations.

On October 3, 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment
or Disposal of Long-Lived Assets," which addresses financial accounting and
reporting for the impairment or disposal of long-lived assets. While SFAS No.
144 supersedes FASB Statement No. 121, "Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to Be Disposed Of," it retains many of
the fundamental provisions of that Statement. Statement No. 144 also supersedes
the accounting and reporting provisions of APB Opinion No. 30, "Reporting the
Results of Operations-Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions," for the disposal of a segment of a business. However, it retains
the requirement in Opinion No. 30 to report separately discontinued operations
and extends that reporting to a component of an entity that either has been
disposed of (by sale, abandonment, or in a distribution to owners) or is
classified as held for sale. Statement No. 144 is effective for fiscal years
beginning after December 15, 2001 and interim periods within those fiscal years.
The Company will review and assess the impact of SFAS No. 144 on its financial
position and results of operations.

Note (3) Contingencies

As a result of the nature of the persons who received certain options to
purchase common stock of the Company granted prior to February 22, 2001 under
the Company's 2000 Equity Incentive Plan and the vesting provisions of these
options, the Company may have violated California state securities laws because
it did not qualify these options under California state securities laws. Because
these option grants may not have been qualified under California state
securities laws, persons residing in California who received these options may
have a claim against the Company. Accordingly, the Company currently intends to
offer to repurchase outstanding options to purchase shares of its common stock
granted under its 2000 Equity Incentive Plan prior to February 22, 2001 to
persons who resided in California at the time of grant.

On August 28, 2001, Tellabs Operations, Inc. filed an action against Riverstone
in the Chancery Division of the Circuit Court of Cook County, Illinois alleging
that Riverstone breached the Strategic Alliance Agreement dated as of November
17, 2000 between Riverstone and Tellabs and committed various torts by (i)
failing to provide Tellabs with CMTS products that met the technical
specifications in the agreement; (ii) misrepresenting to Tellabs the technical
capabilities of Riverstone's CMTS products; and (iii) improperly selling
Riverstone products to Tellabs customers. Tellabs' complaint seeks compensatory
damages in excess of $10 million, plus punitive damages and costs in unspecified
amounts. On that same date, Tellabs purported to terminate the agreement and is
seeking a declaratory judgment that it has no further obligations under the
agreement. The Company believes that Tellabs' claims are without merit and
intends to vigorously defend this proceeding. On August 29, 2001, Riverstone
filed suit against Tellabs in the Superior Court for Santa Clara County,
California seeking compensatory damages in excess of $60 million, including over
$56 million in unfulfilled minimum purchase obligations Tellabs was required to
make under the agreement. Riverstone has filed a motion in the Illinois case to
have that action dismissed or stayed, so that the parties' dispute can be heard
in the first instance in the California case.

ITEM 2. 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 our consolidated financial statements
and related notes appearing elsewhere in this Form 10-Q. The discussion below
contains forward-looking statements that involve risks and uncertainties,
including statements relating to anticipated costs and expenses, mix of revenues
and plans for introducing new products or services. Our actual results could
differ materially from the results discussed in these forward-looking
statements.


The following information should be read in conjunction with the Company's
Annual Report on Form 10-K filed on June 1, 2001 with the Securities and
Exchange Commission and "Risk Factors That May Affect Future Results and Market
Price of Stock" included herein.

Overview

We are a leading provider of Internet infrastructure equipment to
telecommunications service providers in the metropolitan area network. The
metropolitan area network, or MAN, encompasses service providers, the Internet
infrastructure connecting these service providers with their customers and the
Internet backbone. Our routers contain bandwidth management and provisioning,
accounting and billing, quality of service and content delivery capabilities
that enable service providers to deliver advanced applications and
differentiated services to their customers. The majority of our revenue comes
from sales of our RS router family. We account for sales in which we receive
equity as consideration by estimating the fair value of the equity instrument
through an independent appraisal or a recent equity transaction received by the
issuer from an unrelated third party.

Our industry has experienced erosion of average selling prices. We anticipate
that the average selling prices of our products will decrease in the future in
response to competitive pricing pressures, which may reduce our gross margins or
revenues. We expect our quarterly gross margins to fluctuate with changes in our
product mix. Most of our sales within the United States have been through direct
sales channels. We intend to add and maintain a limited number of strategic
distribution relationships, including with key original equipment manufacturers,
or OEMs, who may offer products or distribution channels that complement ours.
International sales are made through a combination of direct and indirect sale
efforts. We initiated sales and marketing efforts internationally during fiscal
2001, focusing initially on Europe and Asia. As part of this effort, we have
negotiated separate reseller agreements with various distributors and network
integrators in Europe and Asia.

Revenue Recognition. We generally recognize revenue upon shipment of products,
provided that there is no uncertainty of customer acceptance, there is a
contract or a purchase order, the sales price is fixed and determinable and we
believe collectibility is probable. If uncertainties exist, revenue is
recognized when these uncertainties are resolved. Revenues from service and
maintenance contracts are deferred and recognized ratably over the period the
services are performed, typically twelve months or less. We accrue estimated
warranty costs and sales returns and allowances at the time of shipment based on
contractual rights and historical experience. We do not sell our RapidOS
operating system software on a stand-alone basis.

Cost of Revenues. Cost of revenues include costs of raw materials, direct labor,
manufacturing overhead and amounts paid to third-party contract manufacturers,
and other costs related to warranty and contractual obligations and customer
service and support.

Research and Development. Research and development expenses consist primarily of
salaries and related personnel expenses, consultants and outside service
provider fees, non-recurring engineering charges and prototype costs related to
the development, testing and enhancement of our ASICs and software, and the
depreciation of property and equipment related to these activities. Our research
and development efforts can require significant expenditures, the timing of
which can cause quarterly variability in our expenses. We believe continued
investment in product enhancements and new product development are critical to
attain our strategic objectives, and 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, and trade shows, advertising and promotional
expenses. We intend to expand our worldwide direct and indirect sales
organizations substantially by hiring additional sales personnel and
establishing additional sales offices. We plan to initiate additional marketing
programs to support our existing and new products and to build brand awareness
of the Riverstone name. We believe that continued investment in sales and
marketing is critical to our success and expect these expenses to increase in
absolute dollars in the future.

                                       11


General and Administrative. General and administrative expenses consist
primarily of employee compensation and related expenses, professional and
contractor fees, finance, legal, facilities, human resources and provisions for
doubtful accounts. Included in general and administrative expenses are expenses
for services provided by Cabletron under our services agreement with them
through August 6, 2001. Before the effective date of the services agreement,
March 1, 2000, Cabletron allocated to us general and administrative expenses
that it incurred on our behalf, based on headcount and revenue. We expect
general and administrative expenses to increase slightly in absolute dollars
over the next year as we complete the build-out of our own administrative
infrastructure.

Additional Option and Warrant Obligation. On August 6, 2001, Cabletron
distributed the 99,205,992 shares of Riverstone's common stock that it held to
its stockholders. In connection with this stock distribution, we were required
to issue to certain of Cabletron's investors warrants to purchase 230,364 shares
of our common stock, which number of shares was based on the number of shares
that the investors would have received in the distribution if the investors had
exercised the Cabletron warrants they held immediately before the record date of
the distribution. These warrants have a weighted average exercise price of
$29.18 and will expire on August 30, 2007. In addition, in connection with the
distribution, we were required to grant options under our 2000 Equity Incentive
Plan to purchase 3,146,272 shares of our common stock to those persons who held
compensatory Cabletron stock options. These options have a weighted average
exercise price of $7.93.

Stock-based compensation. We have recorded approximately $11.1 million of
unearned stock-based compensation primarily related to stock option grants to
employees based on the excess of the determined fair market value over the
exercise price at date of grant. This compensation expense is being recognized
over the four-year option vesting period on a straight-line basis. In the second
quarter of fiscal year 2002, we additionally recorded an expense $435,000 of
stock-based compensation relating to employment termination. We expect to
recognize stock-based compensation expenses of $3.2 million, $2.7 million, $2.7
million and $1.6 million during our fiscal years 2002, 2003, 2004 and 2005.

Basis of Presentation

Our fiscal year 2001 condensed consolidated financial statements have been taken
from the consolidated financial statements of Cabletron using historical results
of operations and historical basis of the assets and liabilities attributable to
our operations. The consolidated financial statements for fiscal 2001 and 2002
include allocations to us of Cabletron corporate expenses, including legal,
accounting, treasury, real estate, information technology, distribution,
customer services, sales, marketing, engineering and other corporate services
and infrastructure costs. All of the allocations and estimates in our financial
statements are based upon assumptions that our management and Cabletron's
management believe to be reasonable reflections of the cost of services provided
or the benefit received by us.

The financial information presented in this Form 10-Q is not indicative of our
financial position, results of operations or cash flows in the future, nor is it
necessarily indicative of what our financial position, results of operations or
cash flows would have been had we been a separate, stand-alone company for the
periods presented.

Three and six months ended September 1, 2001 and September 2, 2000

Net Revenues. Net revenues were $55.3 million for the three months ended
September 1, 2001 and $20.6 million for the three months ended September 2,
2000, representing an increase of $34.7 million or 169% from the second quarter
of fiscal year 2001 to the second quarter of fiscal year 2002. Net revenues were
$99.4 million for the six-month period ended September 1, 2001 and $36.3 million
for the six-month period ended September 2, 2000, representing an increase of
$63.1 million or 174% from the first six months of fiscal year 2001 to the first
six months of fiscal year 2002. The increase in net revenues was primarily due
to the addition of new customers both in the United States and internationally.
During the first six months of fiscal year 2002, revenues from international
regions grew at a faster rate than revenues from within the United States.
International revenues for the second quarter of fiscal 2002 were 49% of
revenues compared with 28% of revenues in the same period of fiscal 2001. For
the first six months of fiscal 2002, international revenues were 44% of revenues
compared with 25% in the same period of fiscal year 2001.

Cost of Revenues. Cost of revenues consists primarily of amounts paid to a
third-party manufacturer for purchased materials and services, and manufacturing
and professional services personnel and related costs. Cost of revenues for the
three months ended September 1, 2001 were $23.8 million with a gross margin of
56.9%, compared to cost of revenues of $9.2 million for the three months ended
September 2, 2000 and a gross margin of 55.4%. Cost of revenues for the six
months ended September 1, 2001 were $43.0 million with a gross margin of 56.8%,
compared to cost of revenues of $16.4 million for the six months ended September
2, 2000 and a gross margin of 54.8%. The increase in cost of revenues is
primarily related to the increase in sales volume. We expect cost of revenues to
continue to increase as net revenues increase. The improvement in gross margin
is primarily attributable to economies of scale achieved from increased sales
levels.

Research and Development. Research and development expenses excluding stock-
based compensation were $13.6 million for the three months ended September 1,
2001, an increase of $3.3 million over the comparable quarter of fiscal year
2001. Research and development expenses excluding stock-based compensation were
$26.9 million for the six months ended September 1, 2001, representing an
increase of $6.4 million over the comparable period a year ago. Research and
development expenses, excluding stock-based compensation, as a percentage of net
revenues were 25% and 50% of net revenues in the three months ended September 1,
2001 and September 2, 2000, respectively. For the first six months of fiscal
years 2002 and 2001, research and development expenses, excluding stock-based
compensation, as a percentage of net revenues were 27% and 56%, respectively.
The increase in absolute dollars represented the Company's continued investments
in personnel and related costs to support the Company's product development
efforts.

Sales and Marketing. Sales and marketing expenses excluding stock-based
compensation were $13.7 million for the three months ended September 1, 2001, an
increase of $6.1 million over the comparable quarter in fiscal year 2001. Sales
and marketing expenses excluding stock-based compensation were $26.8 for the six
months ended September 1, 2001, representing an increase of $11.9 million over
the comparable period of fiscal year 2001. Sales and marketing expenses,
excluding stock-based compensation, as a percentage of net revenues were 25% and
37% of net revenues in the three months ended September 1, 2001 and September 2,
2000, respectively. For the first six months of fiscal years 2002 and 2001,
sales and marketing expenses, excluding stock-based compensation, as a
percentage of net revenues were 27% and 41%, respectively. The increase in
absolute dollars in sales and marketing expenses was due primarily to the
addition of sales and marketing personnel to support increased sales and
marketing activities.

General and Administrative. General and administrative expenses excluding stock-
based compensation were $5.8 million for the three months ended September 1,
2001, an increase of $2.7 million over the comparable quarter in fiscal year
2001. General and administrative expenses excluding stock-based compensation
were $10.8 million for the six months ended September 1, 2001, representing an
increase of $4.5 million over the comparable period of fiscal year 2001. General
and administrative expenses, excluding stock-based compensation, as a percentage
of net revenues were 10% and 15% in the three months ended September 1, 2001 and
September 2, 2000, respectively. first fiscal quarter of 2002 and 2001,
respectively. For the first six months of fiscal years 2002 and 2001, general
and administrative expenses, excluding stock-based compensation, as a percentage
of net revenues were 11% and 17%, respectively. The increase in absolute dollars
was primarily due to the addition of personnel to support the increase in
revenue and general corporate expenses consistent with the increased scale of
operations.

Stock-based Compensation. We recorded total deferred compensation of $11.1
million during the fiscal year ended March 3, 2001, related to stock option
grants to employees and an employee change in status, of which approximately
$685,000 was expensed during the three months ended September 1, 2001. In the
second quarter of fiscal year 2002, we recorded an additional $435,000 of stock-
based compensation expense relating to employment termination. Stock-based
compensation expense was classified as cost of revenues or operating expense
depending upon the classification of the respective employee.

Interest Income, Net. Interest income primarily consists of income on available-
for-sale investments. Interest income was $2.7 million for the three months
ended September 1, 2001, compared with $770,000 for the three months ended
September 2, 2000. The increase in interest income is a direct result of
increased cash and investment balances, resulting from the Company's initial

                                      13


public offering in February 2001, the exercise of warrants by strategic
investors at the time of the initial public offering, proceeds from the issuance
of common stock to Cabletron in July 2001 and stock option exercises in the
second quarter of fiscal year 2002.


Liquidity and Capital Resources

Prior to our initial public offering, Cabletron administered our cash. We
transferred cash receipts related to our business to Cabletron periodically, and
Cabletron provided funds to cover our disbursements. On March 3, 2001, we
reported cash of $31.2 million in our intercompany cash account. Cabletron
administered this intercompany account, as provided by our services agreement
with them, up to the completion of our separation from Cabletron in August 2001
when all intercompany accounts were settled. We completed our initial public
offering on February 22, 2001 and realized net proceeds of $108.8 million. At
the completion of our initial public offering, we also received $46.6 million
from the exercise of stock purchase rights by strategic investors. Pursuant to a
transfer agreement between Cabletron and us, on July 24, 2001, we issued
7,117,757 shares of our common stock to Cabletron in exchange for approximately
$122.2 million in cash and certain strategic investments. At September 1, 2001,
we had cash and cash equivalents of $153.1 million and short-term investments of
$68.4 million compared with $136.8 million cash and cash equivalents and short-
term investments of $21.5 million at March 3, 2001. The cash and short-term
investment accounts have been managed by us, and we began managing the cash from
our intercompany account with Cabletron upon the completion of our separation
from Cabletron. Cash equivalents consisted of government and non-government debt
securities and money market funds with original maturities of less than three
months. Short-term investments were comprised of U.S debt securities and
commercial paper with original maturities greater than three months but less
than a year. Long-term investments primarily consisted of government and non-
government debt securities with original maturities greater than a year and
minority investments in non publicly traded companies.

Net cash used in operating activities for the six months ended September 1, 2001
and September 2, 2000 was $4.7 million and $5.6 million, respectively. Cash used
by operating activities in these periods was primarily attributable to general
operating expenses, and increases in inventories and other working capital
items.

Net cash used in investing activities of $139.5 million for the six months ended
September 1, 2001 consisted of capital expenditures, purchases of short-term,
long-term and restricted investments. For the six months ended September 2, 2000
investing activities of $7.2 million were primarily capital expenditures.
Capital expenditures during both periods include production equipment, research
and development equipment, computers, enterprise resource planning software
applications and facility-related improvements.

Cash provided by financing activities was $129.4 million for the six months
ended September 1, 2001, as compared to $63.9 million for the six months ended
September 2, 2000. The net cash provided for the six months ended September 1,
2001 primarily consisted of proceeds from issuance of common stock, exercise of
stock options and net transfers from Cabletron under our agreement with them.
The net cash provided for the six months ended September 2, 2000 was primarily
attributable to net transfers from Cabletron.

Our future capital requirements will depend on a number of factors, including
the timing and rate of the expansion of our business. We anticipate an increase
in our capital expenditures to support growth in operations and infrastructure.
However, our underlying assumed levels of revenues and expenses may prove to be
inaccurate. We may need to raise additional funds through public or private
financing or other arrangements to:

    .    support more rapid expansion of our business than we anticipate;
    .    develop and introduce new or enhanced products or services;
    .    respond to competitive pressures;
    .    invest in or acquire businesses or technologies; or
    .    respond to unanticipated requirements or developments.


Financing may not be available to us, if needed, on favorable terms or at all.
If we raise additional funds through the issuance of equity securities, dilution
to existing stockholders may result. If sufficient funds are not available, we
may be unable to introduce new products and services, expand our sales force and
service organization or compete effectively in our markets, any of which could
materially harm our business, financial condition and results of operations.

We believe that our existing cash and cash equivalents will be sufficient to
meet our anticipated cash needs for working capital and capital expenditures
over the next twelve months.

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

Risks Related to Riverstone

We have a general history of losses and cannot assure you that we will operate
profitably in the future.

We achieved profitability for the first time in the second quarter of fiscal
year 2002. Net income for the second quarter of fiscal year 2002 was $64,000.
However, the financial position, results of operations and cash flow of the
second quarter of 2002 may not necessarily be indicative of results to be
expected for the full fiscal year or any future periods. We cannot be certain
that we will realize sufficient revenue to sustain profitability in the future.
Portions of our historical financial data are based on Cabletron's financial
statements. During fiscal 2000 and 2001, we incurred net losses of $37.4 million
and $65.8 million, respectively. During the first quarter of fiscal 2002, our
net loss amounted to $4.7 million. We anticipate incurring significant and
increasing sales and marketing, product development and general and
administrative expenses, requiring us to realize significantly higher revenue to
sustain profitability.

An economic slowdown is being experienced by the United States, Europe and Asia-
Pacific, and if the slowdown continues for an extended period of time or if any
of these economies were to enter a recession, our ability to increase or sustain
our revenues may be limited. The events on September 11 in New York, N.Y. and
Washington, D.C. have increased the uncertainty in the U.S. economy and may have
increased the chances the current slowdown in the U.S. economy will become a
recession. These events have decreased our ability to project our revenue in
future quarters and may decrease the amount of funds our customers commit to
information technology infrastructure spending. Any reduction in or delay of
capital spending by our customers due to the events of September 11 will reduce
our future revenue and profitability.

Our exclusive focus on sales to service provider customers subjects us to risks
that may be greater than those for providers with a more diverse customer base.

Our customers consist of carriers, content hosting providers and metropolitan
area service providers, as well as traditional Internet service providers, whose
businesses depend on the continuing demand for differentiated services by their
customers. If this demand does not continue or the Internet does not continue to
expand as a widespread communications medium and commercial marketplace, the
demand for our products could decline. Our exposure to this risk is greater than
other vendors who sell to a more diversified customer base. We believe that
there are risks arising from doing business with service providers in these
markets that may not be faced by our competitors in their relationships with
corporate and other customers, including:

    .    any failure of a service provider's service to its customers that
         it attributes to our products, whether or not our products actually
         failed, which could lead to substantial negative publicity and
         undermine our efforts to increase our sales;

    .    the low level of brand loyalty demonstrated by service providers,
         which may cause them to switch to another supplier that provides, or
         that they believe provides, superior performance or cost-
         effectiveness;

    .    the introduction, or the planned introduction, of new products and
         product enhancements, which could cause service providers to cancel,
         reduce or delay existing orders; and

    .    service providers that are heavily dependent upon financing,
         particularly from the high yield debt market, to build out their
         infrastructure, who may decrease their infrastructure purchases if
         interest rates increase or if credit availability in these markets
         decreases.

    The occurrence of one or more of these events is likely to harm our
operating results.

Our quarterly revenue and operating results are likely to fluctuate,
particularly as we expand and if, as expected, our expenses rise, which could
cause us to miss quarterly revenue targets and result in a decline in our stock
price.

We base our operating expenses on anticipated revenue trends. A high percentage
of our expenses remain relatively fixed despite changes in revenue, including
marketing, research and development and general administrative expenses and
expenses for

                                      15


employee compensation other than sales commissions. This means that any failure
to achieve anticipated revenues could cause our quarterly operating results to
fall below the expectations of public market analysts or investors, which could
cause the price of our common stock to fall. As we expand, we expect our
expenses to rise significantly, which increases the magnitude of this risk.

Our quarterly 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;

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

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

    .    the timing and amount of non-cash stock based compensation charges;

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

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


Due to these factors, we believe that you should not rely on period-to-period
comparisons of our operating results as an indicator of our future performance.

We generally do not have binding commitments from our customers and if
significant customers cancel, reduce or delay a large purchase, our revenues may
decline and the price of our stock may fall.

Historically, a limited number of customers have accounted for a significant
portion of our revenue. For fiscal year 2001, Telseon accounted for over 10% of
our net revenue and during the first quarter of fiscal year 2002, IntelliSpace
accounted for over 10% of our net revenue. In the quarter ended September 1,
2001, Telindus accounted for over 10% of our net revenue. Customers making large
purchases from us are likely to vary over time, due to changes in our product
cycles, customer needs, competition or economic circumstances. For example,
Vitts Networks and Metricom have recently filed for bankruptcy and ceased
operations and Tellabs is purporting to terminate its agreement with us.
Although our largest customers may vary from period to period, we anticipate
that our operating results for any given period will continue to depend
significantly on large orders from a small number of customers. We generally do
not have binding commitments from most of our customers. If any of our large
customers cancel, reduce or delay purchases, our revenue and profitability would
be harmed because of our dependence on large customers.

Because the purchase of our products often represents a significant decision on
the part of potential customers, we may expend significant resources on
potential customers without achieving actual sales.

Purchases of our products often represent a significant strategic decision and
capital investment by our customers related to their communications
infrastructure and typically involve significant internal procedures involving
the evaluation, testing, implementation and acceptance of new technologies. This
evaluation process frequently results in a lengthy sales process, often ranging
from one month to longer than a year, and purchases of our products are subject
to a number of significant risks, including customer budgetary constraints and
internal acceptance reviews. During this time we may incur substantial sales and
marketing expenses and expend significant management effort. The length of the
sales cycle, and the magnitude of our investment in the sales process, is more
substantial for our service provider customers than it would typically be with
corporate customers. If sales forecasts from a specific customer for a
particular quarter are not realized in that quarter, we may be unable to
compensate for the shortfall, which could harm our operating results.

We may be unable to expand our sales and direct and indirect distribution
channels, which may hinder our ability to target multiple levels of a
prospective customer's organization and increase sales and revenues.

Our products and services require a sophisticated sales and marketing effort
targeted at several levels within a prospective customer's organization. Unless
we expand our sales force and maintain high levels of marketing activity, we
will be unable to increase revenues. Although we plan to continue to hire
additional sales personnel, competition for qualified sales personnel is
intense, and we may be unable to hire the sales personnel we require.

                                      16


Our sales and distribution strategy relies on value-added resellers, original
equipment manufacturers, or OEMs, our direct and indirect international sales
efforts and our ability to package our products into a complete network
infrastructure solution by working with other technology vendors. If we are
unable to establish new value-added reseller or OEM relationships, or if our
OEMs and valued-added resellers are unsuccessful in distributing our products,
our sales could suffer. Because we are not a vertically integrated network
infrastructure provider, if we fail to maintain existing technology vendor
relationships or to establish new ones, we will be unable to satisfy our
customers' need for complete, fully-integrated solutions and our business could
suffer.

Certain of our customers rely on us to arrange financing for our products, which
subjects us to credit and market risks.

Certain of our customers do not have or do not wish to commit the financial
resources required to purchase our products without financing, and these
customers expect us to arrange their financing. These financing arrangements
expose us to our customers' credit risk and in the past we have experienced
customer defaults. If customers default on their financing payments in the
future, our recognition of revenue from those customers will be harmed. Due to
recent public market volatility, a number of our current or prospective
customers may be unable to raise funding through the issuance of their equity
securities or otherwise in a timely fashion. This difficulty could result in an
increased need for financing provided either by us or with our assistance and an
increased risk of customer default. In the past, we benefited from Cabletron's
resources and credit in arranging financing for our customers. As a result of
our separation from Cabletron, we are a much smaller, stand-alone company, which
could impair our ability to provide or arrange and support customer financing.
If third party financing were to become less available due to credit market
factors, our ability to arrange third party financing for our customers could be
significantly limited, potentially resulting in reduced revenues.

We purchase several key components for our products from single or limited
sources and could lose sales if these sources fail to fulfill our needs.

We purchase several key components used in the manufacture of our products from
single or limited sources and are dependent upon supply from these sources to
meet our needs. We have worked with NEC and Agere to develop several of our key
proprietary application specific integrated circuits, or ASICs. These
proprietary ASICs are very complex, and NEC and Agere are our sole source
suppliers for the specific types of ASICs that they supply to us. We do not have
a long-term fixed price or minimum volume agreement with either of these
suppliers. Should we encounter problems with NEC or Agere, we would not be able
to develop an alternate source in a timely manner, which could hurt our ability
to deliver our routers.

We also purchase other critical components from single or limited sources. We
are likely to encounter shortages and delays in obtaining these or other
components in the future which could materially harm our ability to meet
customer orders.

Recently, California has been experiencing a shortage of electric power supply
that has resulted in intermittent loss of power in the form of rolling
blackouts. While we have not encountered any shortages or delay in obtaining key
components as a result of this energy situation, continued or extended blackouts
could adversely affect our suppliers' ability to produce and deliver key
components on a timely basis.

We base our purchasing decisions on a forecast of anticipated orders of our
products, and if we miscalculate our needs or are not able to obtain necessary
components, we could be harmed.

We use a forward-looking forecast of anticipated product orders to determine our
material requirements, and if customer orders do not match forecasts, we may
have excess or inadequate inventory of materials and components. In the past, we
have experienced shortages of some components, resulting in delays in filling
orders. For example, recent high demand in the cellular phone industry for
Tantalum capacitors, a component required to manufacture our products, has led
to shortages and price increases for these capacitors. We have also experienced
delays in the prototyping of our ASICs during initial product development, which
in turn has led to delays in product introductions. If we cannot obtain
necessary components, we may not be able to meet customer orders and our
business and results of operations could suffer.

We depend on a single contract manufacturer for substantially all of our
manufacturing requirements, and a failure by this contract manufacturer would
impair our ability to deliver products.

We outsource all of our manufacturing to one company, Flextronics International,
Ltd., which manufactures our products in San Jose, California. If the demand for
our products grows, we will need to increase our material purchases and our
contract manufacturing capacity with Flextronics or add additional contract
manufacturers. Our existing and future contract manufacturers may not meet our
future requirements. We have experienced a delay in product shipments from our
contract manufacturer in the past, which in turn delayed product shipments to
our customers. We may in the future experience similar and other problems, such
as insufficient quantity of product, which could materially harm our business
and operating results. While Flextronics has not experienced any power failures
to date as a result of the recent California energy shortage that have prevented
its ability to

                                      17


manufacture our products, continued or extended blackouts could adversely affect
Flextronics' ability to manufacture our products and meet scheduled delivery
needs. The inability of our contract manufacturer to provide us with adequate
supplies of high-quality products or the loss of our contract manufacturer would
cause a delay in our ability to fulfill orders while we obtain a replacement
manufacturer and would have a material adverse effect on our business, operating
results and financial condition.

Substantially all of our revenues come from sales of our RS router family,
making us dependent on widespread market acceptance of these products.

Substantially all of our revenues result from sales of our RS router family.
Continuing market acceptance of our products is critical to our future success,
and we are more dependent on the market acceptance of our individual product
family than competitors with broader product offerings. Factors that may affect
the market acceptance of our products include:

    .    adoption of advanced routing and switching products and technologies;

    .    the performance, price and total cost of ownership of our products;

    .    the availability and price of competing products and technologies;

    .    brand recognition of the Riverstone name; and

    .    the success and development of our sales and marketing organizations
         and resellers.

    If we fail to achieve market acceptance for our router family, our revenues
may be harmed.


The market for network equipment is subject to rapid technological change and if
we fail to accurately predict and respond to market developments or demands, we
will be unable to compete successfully.

The market for network equipment is characterized by rapid technological change,
frequent new product introductions, changes in customer requirements and
evolving industry standards. Our future performance will depend on our
successful development and introduction and the market acceptance of new and
enhanced products that address customer requirements in a cost-effective manner.
We may be unsuccessful in completing the development or introduction of these
product enhancements or new products on a timely basis or at all. The failure of
these enhancements or new products to operate as expected could delay or prevent
future sales. Developments in routers and routing software could also
significantly reduce demand for our product. Alternative technologies and
customer requirements could achieve widespread market acceptance and displace
the technologies, protocols and service requirements on which our product lines
are based. Our technological approach may not achieve broad market acceptance,
and other technologies or devices may supplant our approach.

If we and the third parties providing services for us are unable to deliver the
high level of customer service and support demanded by our customers, we may
lose customers and our operating results will suffer.

Our customers demand a high level of customer service and support. Our customer
service and support functions are provided by a combination of our internal
product support group and Digital Equipment (India). We are in the process of
transitioning the services provided by Digital Equipment (India) to internal
field service and support services. We may experience a disruption in our
ability to support customers during this transition period, which could
significantly reduce customer satisfaction and impair our ability to retain
customers and make future sales. We are also considering other third parties to
provide certain customer support services. We may be unable to manage
effectively those third parties who provide support services for us and they may
provide inadequate levels of customer support.

Our products are very complex and undetected defects may increase our costs and
harm our reputation with our customers.

Networking products are extremely complex and must operate successfully with
equally complex products of other vendors. These products frequently contain
undetected software or hardware errors when first introduced or as new upgrades
are released. Additionally, the pressures we face to be the first to market new
products, increases the possibility that we will offer products in which we or
our customers later discover errors. We have experienced new product and product
upgrade errors in the past and expect similar problems in the future. These
problems could result in our incurring significant warranty and repair costs,
divert the attention of our engineering personnel from our product development
efforts and cause significant customer relations problems and our stock price to
fall.

                                      18


We have limited ability to engage in acquisitions and other strategic
transactions using our equity because of the federal income tax requirements for
a tax-free distribution.

For the distribution of our stock by Cabletron (now known as Enterasys) to
qualify as tax-free to Enterasys, there must not be a change in ownership of 50%
or greater in either the voting power or value of either our stock or Enterasys'
stock that is considered to be part of a plan or series of transactions related
to the distribution. If there is a direct or indirect acquisition of our or
Enterasys' stock by one or more persons during the four-year period beginning
two years before and ending two years after the distribution, it will be
presumed to be part of a plan or series of related transactions related to
Enterasys' intended distribution of our stock. Unless this presumption is
successfully rebutted, the distribution will be taxable to Enterasys.

We have entered into a tax sharing agreement with Enterasys, Aprisma and GNTS.
This agreement requires us to indemnify the other parties if the distribution by
Cabletron of its Riverstone shares does not qualify as tax-free due to actions
we take or that otherwise relate to us, including any change of ownership of us.
The process for determining whether a change of ownership has occurred under the
tax rules is complex. If we do not carefully monitor our compliance with these
rules, we might inadvertently cause a change of ownership to occur, triggering
our obligation to indemnify Enterasys and the other parties to the tax sharing
agreement. Our obligation to indemnify these parties if a change of ownership
causes the distribution not to be tax-free could discourage or prevent a third
party from making a proposal to acquire us.

For the reasons described above, our ability to use our stock for acquisitions
and other similar strategic transactions or for compensation for employees and
others is restricted. Many of our competitors use their equity to complete
acquisitions, to expand their product offerings and speed the development of new
technology and to attract and retain employees and other key personnel, giving
them a potentially significant competitive advantage over us.

We jointly own with Enterasys some of our intellectual property, and our
business could be harmed if Enterasys uses this intellectual property to compete
with us.

Intellectual property that relates to a family of ASICs used in both our RS
router family and Enterasys' Smart Switch Router product family is owned jointly
by Enterasys and us. Enterasys is primarily a provider of local area network
products for the enterprise market. There are no contractual provisions that
prohibit Enterasys from developing products that are competitive with our
products, including products based upon the jointly assigned intellectual
property. If Enterasys is acquired by one of our competitors, there are no
contractual provisions that would prohibit the combined company from developing
products competitive with our products.

Our limited ability to protect our intellectual property may hinder our ability
to compete.

We rely on a combination of patent, copyright, trademark and trade secret laws
and restrictions on disclosure of confidential information to protect our
intellectual property rights. We cannot assure you that any patents that we hold
will protect our intellectual property or will not be challenged by third
parties. Other parties may also independently develop similar or competing
products that do not infringe our patents. Although we attempt to protect our
intellectual property rights, we may be unable to prevent the misappropriation
of our intellectual property, 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 claims that our intellectual property infringes upon the
proprietary rights of others, and a successful claim could harm our ability to
sell and develop our products.

If other parties claim that our products infringe upon their intellectual
property we would be forced to defend ourselves or our customers, manufacturers
or suppliers against those claims. We could incur substantial costs to prosecute
or defend those claims. A successful claim of infringement against us and our
failure or inability to develop non-infringing technology or license the
infringed technology on acceptable terms and on a timely basis could harm our
business, results of operations and financial condition.

We have recently begun to expand our international sales effort, and marketing
and distributing our products outside of the United States may require increased
expenses and greater exposure to risks that we may not be able to successfully
address.

Our growth strategy depends in part on the expansion of our international sales
and operations. International sales, which were negligible in fiscal 1999,
increased to 23% of our revenue in fiscal 2000 and 32% in fiscal 2001. During
the first and second fiscal quarter 2002, our international sales were 38% and
49%, respectively. The international market for our products is less mature than
the market in the United States, and our strategy of selling to service
providers that operate in the metropolitan area network

                                      19


may be unsuccessful on an international basis. Operating internationally exposes
us to risks such as longer accounts receivable collection cycles, difficulties
in staffing and managing operations across disparate geographic areas and
tariffs, export controls and other trade barriers. We conduct our international
sales in either U.S. dollars or local currencies and a change in the value of
the U.S. dollar relative to foreign currencies could make our products less
competitive in international markets. We are also subject to fluctuations in
exchange rates between the U.S. dollar and the particular local currency. We may
determine to engage in hedging transactions to minimize the risk of fluctuations
and if we are not successful in managing hedging transactions, we could incur
losses.

If we fail to address the strain on our resources caused by our growth or if we
are unable to attract and retain qualified personnel, we may not be able to
achieve our objectives and our business could be harmed.

We have experienced a period of rapid growth and expansion, which has placed,
and continues to place, a significant strain on our management, operational and
financial resources. From February 28, 1999 to September 1, 2001, the number of
our employees increased from 163 to 506 and is expected to continue to increase.
Our management team has only been recently formed and has had limited experience
managing rapidly growing companies. Some members of our management team have
joined us only recently. Our success depends to a significant degree upon the
continued contributions of our key management, engineering, sales and marketing,
customer support and manufacturing personnel, many of whom would be difficult to
replace. In particular, we believe that our future success is highly dependent
on Romulus Pereira, our president and chief executive officer.

We believe our future success also depends on our ability to attract and retain
highly skilled managerial, engineering, sales and marketing, finance, customer
support and manufacturing personnel. Competition for these personnel is intense,
especially in the San Francisco bay area, and we have had difficulty hiring
employees in the timeframe we desire, particularly software and hardware
engineers. We may be unsuccessful in attracting and retaining personnel. The
loss of the services of any of our key personnel, the inability to attract or
retain qualified personnel in the future or delays in hiring required personnel,
particularly engineers and sales personnel, could make it difficult for us to
manage our business and meet key objectives, such as timely product
introductions.

We rely on independent service providers to supply our back-office functions,
and if they fail to deliver adequate services, our business will suffer.

We rely on service providers to supply us with many of our operational and back-
office functions, including human resources applications, enterprise resource
management applications and customer relationship management applications.
Although these functions are critical to our business, we neither own the
software that performs these functions nor, in some cases, the hardware on which
these programs and our data reside. If there is a significant degradation or
failure in service, we may be unable to quickly and cost-effectively transition
to other service providers or provide the necessary functionality ourselves and
our business could be disrupted.

Risks Related to Our Industry

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

The market for network equipment is very competitive and has historically been
dominated by Cisco Systems. Other principal competitors include established
companies such as Extreme Networks, Foundry Networks, Juniper Networks, Lucent,
Nortel Networks and Siemens. We also experience competition from a number of
other smaller public and private companies. These competitors may have developed
or could in the future develop new technologies that compete with our products
or even make our products obsolete. Consolidation in our industry is occurring
and is likely to continue. Future acquisitions by, and mergers among, our
competitors and potential competitors could expand their product offerings and
accelerate their development of new technologies, providing them with a
competitive advantage.

Many of our competitors have significantly more established customer support and
professional services organizations and substantially greater financial
resources than we do. Many of our competitors also have much greater name
recognition and have a more extensive customer base and broader customer
relationships and product offerings than we do. These companies can rely on
their customer bases and broader product offerings and adopt aggressive pricing
policies to gain market share. We expect that competitive pressures may result
in price reductions, reduced margins and loss of market share, which would
materially harm our business, results of operations and financial condition.

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

Our industry has experienced rapid erosion of average selling prices. We
anticipate that the average selling prices of our products

                                      20


will decrease in the future in response to competitive pricing pressures,
increased sales discounts, new product introductions by us or our competitors
and increasing availability of relatively inexpensive standard microprocessors
that can perform some of our products' functionality. If we are unable to
achieve sufficient cost reductions and increases in sales volumes, this decline
in average selling prices will reduce our revenue and gross margins.

If our products do not comply with complex governmental regulations and evolving
industry standards, our products may not be widely accepted, which may prevent
us from sustaining our revenues or profitability.

The market for network equipment products is characterized by the need to
support industry standards as different standards emerge, evolve and achieve
acceptance. To be competitive, we must continually introduce new products and
product enhancements that meet these emerging standards. We have had to delay
the introduction of new products to comply with third party standards testing.
We may be unable to address compatibility and interoperability issues that arise
from technological changes and evolving industry standards. In the United
States, our products must comply with various governmental regulations and
industry regulations and standards, including those defined by the Federal
Communications Commission, Underwriters Laboratories and Networking Equipment
Building Standards, or NEBS. Internationally, products that we develop may be
required to comply with standards or obtain certifications established by
telecommunications authorities in various countries and with recommendations of
the International Telecommunications Union. If we do not comply with existing or
evolving industry standards or fail to obtain timely domestic or foreign
regulatory approvals or certificates, we will be unable to sell our products
where these standards or regulations apply, which may prevent us from sustaining
our revenues or achieving profitability.

Risks Related to Our Separation from Cabletron

Our historical financial information may not be representative of our results as
a separate company.

Our consolidated financial statements are based on the consolidated financial
statements of Cabletron, using the historical results of operations and
historical bases of the assets and liabilities of the Cabletron router and
switch business contributed to us. The historical financial information we have
included in this Report on Form 10-Q does not necessarily reflect what our
financial position, results of operations and cash flows would have been had we
been a separate, stand-alone entity during the periods presented. Cabletron did
not account for us as a separate, stand-alone entity before June 3, 2000. Our
costs and expenses include allocations from Cabletron for centralized corporate
services and infrastructure costs, including:

    .    customer service;

    .    sales;

    .    information technology;

    .    distribution;

    .    legal and accounting;

    .    real estate; and

    .    treasury.

These allocations have been determined on bases that we and Cabletron considered
to be reasonable reflections of the utilization of services provided to or the
benefit received by us. The historical financial information is not necessarily
indicative of what our results of operations, financial position and cash flows
will be in the future. We have not made adjustments to our historical financial
information to reflect many significant changes related to our cost structure,
funding and operations due to our separation from Cabletron, including increased
costs from reduced economies of scale, increased marketing expenses related to
building a company brand identity separate from Cabletron and the increased
costs of being a publicly traded, stand-alone company.

Cabletron no longer provides us administrative services and we no longer use
Cabletron's operational and administrative infrastructure, and our ability to
operate our business may suffer if we do not successfully replace this
infrastructure and services.

Under a services agreement, prior to its distribution of our common stock, we
used Cabletron's administrative infrastructure and Cabletron provided us
centralized corporate functions, including legal, accounting, payroll and other
services. If we are not successful in replacing the services and infrastructure
systems previously provided by Cabletron, or if there is a failure or

                                      21


significant downtime in our systems, our business could be harmed. To
successfully implement and operate our own systems, we must be able to attract
and retain a significant number of highly skilled employees.

We cannot rely on Cabletron to fund our future capital requirements, and
financing from other sources may not be available on favorable terms or at all.

In the past, our capital needs were satisfied by Cabletron. However, following
our separation, Cabletron is no longer a source of funds to finance our working
capital or other cash requirements or to support customer financing. Financing
or financial support from other sources, if needed, may not be available on
favorable terms or at all.

We believe our capital requirements will vary greatly from quarter to quarter.
Capital expenditures, fluctuations in our operating results, financing
activities, acquisitions, investments and inventory and receivables management
may contribute to these fluctuations. We believe that the proceeds from our
initial public offering, our sale of common stock to Cabletron in July 2001 and
our future cash flow from operations, will be sufficient to satisfy our working
capital, capital expenditure and research and development requirements for at
least the next twelve months. However, we may require or choose to obtain
additional debt or equity financing to finance acquisitions or other investments
in our business. Future equity financings may be dilutive to the existing
holders of our common stock. Future debt financings could involve restrictive
covenants. We will likely not be able to obtain debt financing with interest
rates and other terms as favorable as those that Cabletron could obtain.

The plaintiffs in Cabletron's outstanding class action suit might seek to add us
to this litigation or seek payment of any related damages.

Since December 1997, Cabletron has been party to an outstanding class action
suit alleging that during the period of March 3, 1997 through December 2, 1997,
Cabletron released false and misleading information about its operations and
that Cabletron's accounting practices resulted in the disclosure of materially
misleading financial results. The plaintiffs' complaint does not specify the
amount of damages, but if the plaintiffs prevail Enterasys (formerly Cabletron)
could be required to pay substantial damages. The plaintiffs in this matter
might seek to involve us in this litigation or, if they prevail in this
litigation, might seek to recover damages from us, particularly if Cabletron has
insufficient assets.

Conflicts of interest may arise because our directors and executive officers
have ownership interests in Enterasys and  Aprisma.

Many of our directors and executive officers have a substantial amount of their
personal financial portfolios in Enterasys common stock and options to purchase
Enterasys common stock. Our directors also hold options to purchase stock of
Aprisma. Conflict of interest may arise between Enterasys and us in a number of
areas relating to our past and ongoing relationships, including tax,
indemnification, intellectual property and other matters arising from our
separation from Cabletron, which is now Enterasys. These factors could create,
or appear to create, potential conflicts of interest when directors and officers
are faced with decisions that could have different implications for Enterasys,
Aprisma and us. In our certificate of incorporation we have renounced any
interest in business opportunities that are presented to Cabletron (now known as
Enterasys), its subsidiaries other than us, or our officers or directors who are
employees of Enterasys or its subsidiaries other than us at the time the
opportunity is presented.

We could incur significant tax liability if the distribution does not qualify
for tax-free treatment, which could require us to pay Enterasys a substantial
amount of money.

Cabletron (now known as Enterasys) announced that it received from the U.S.
Internal Revenue Service a private letter ruling that its distribution of shares
of our common stock will be free of U.S. federal income taxes. Although private
letter rulings are generally binding on the IRS, Enterasys will not be able to
rely on the ruling if any of the factual representations or assumptions made to
obtain the ruling are, or become, incorrect or untrue in any material respect.
We have entered into a tax sharing agreement which is among Enterasys, Aprisma,
GNTS and us. The tax sharing agreement requires us to indemnify the other
parties if the distribution by Cabletron of its Riverstone shares does not
qualify as tax-free due to actions we take or that otherwise relate to us. In
addition to our liability under the tax sharing agreement, under United States
Federal income tax laws, we would be jointly and severally liable for the
federal income taxes of Cabletron resulting from the distribution being taxable.
This means that even if we do not have to indemnify Enterasys under the tax
sharing agreement because we did not take any specific action to cause the
distribution to fail as a tax-free event, we may still be liable for any part
of, including the whole amount of, these liabilities and expenses if Enterasys
fails to pay them.

Risks Related to Our Stock

Our stock price has been and may continue to be volatile, which could result in
substantial losses for individual stockholders.

                                      22


The stock markets in general, and the markets for high technology stocks in
particular, have experienced extreme volatility that has often been unrelated to
the operating performance of particular companies. For example, during the first
nine months of calendar year 2001, the Nasdaq Composite Index had a closing low
of 1423.19, representing 50.2% less than the closing high of 2859.15 for the
same period. The market price of our common stock has been volatile and we
expect that it will continue to be volatile.

Anti-takeover provisions could make it more difficult for a third party to
acquire us.

We have adopted a shareholder rights plan and declared a dividend distribution
of one right for each outstanding share of common stock to stockholders of
record as of July 26, 2001. Each right entitles the holder to purchase upon
certain events one one-thousandth of a share of our Series A Preferred Stock for
$115. Under certain circumstances, if a person or group acquires 15% or more of
our outstanding common stock, holders of the rights (other than the person or
group triggering their exercise) will be able to purchase, in exchange for the
exercise price, shares of our common stock, and in certain cases, shares of
stock of a company into which we are merged, having a value of double the
exercise price. Because the rights may substantially dilute the stock ownership
of a person or group attempting to take us over without the approval of our
board of directors, our rights plan could make it more difficult for a third
party to acquire us, or a significant percentage of our outstanding capital
stock, without first negotiating with our board of directors regarding such
acquisition.

In addition, our board of directors has the authority to issue up to 2,000,000
shares of preferred stock (of which 200,000 shares have been designated as
Series A Preferred Stock) and to determine the price, rights, preferences,
privileges and restrictions, including voting rights, of those shares without
any further vote or action by the stockholders. The rights of the holders of
common stock may be subject to, and may be adversely affected by, the rights of
the holders of any preferred stock that may be issued in the future. The
issuance of preferred stock may have the effect of delaying, deferring or
preventing a change of control of us without further action by the stockholders
and may adversely affect the voting and other rights of the holders of common
stock. Further, certain provisions of our charter documents may have the effect
of delaying or preventing changes in control or management of Riverstone.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

The primary objective of our investment activities is to preserve principal
while at the same time maximizing the income we receive from our investments
without significantly increasing risk. Some of the securities that we have
invested in may be subject to market risk. This means that a change in
prevailing interest rates may cause the principal amount of the investment to
fluctuate. To minimize this risk, we maintain our portfolio of cash equivalents
and short-term investments in a variety of securities, including commercial
paper, government and non-government debt securities and money market funds. In
general, money market funds are not subject to market risk because the interest
paid on such funds fluctuates with the prevailing interest rate.


Foreign Currency Exchange Risk

The Company, as a result of its global operating and financing activities, is
exposed to changes in foreign currency exchange rates. Management is currently
assessing the exchange rate risk management strategy, including using foreign
exchange forward and option contracts to hedge some balance sheet exposure
against future movements in foreign exchange rates. Gains and losses on the
forward and option contracts are largely offset by gains and losses on the
underlying exposure and consequently a sudden or significant change in foreign
exchange rates would not have a material impact on future net income or cash
flows. We do not now or in the future intend to use derivative financial
instruments for trading purposes.

                                      24


PART II. OTHER INFORMATION

Item 1. Legal Proceedings

A consolidated class action lawsuit raising claims against Cabletron and some
officers and directors of Cabletron was filed in the United States district
court for the district of New Hampshire and, following transfer, is pending in
the district of Rhode Island. The complaint alleges that Cabletron and several
of its officers and directors made materially false and misleading information
about Cabletron's operations and acted in violation of Section 10(b) of and Rule
10b-5 under the Securities Exchange Act of 1934 during the period between March
3, 1997 and December 2, 1997. The complaint also alleges that Cabletron's
accounting practices resulted in the disclosure of materially misleading
financial results during the same period. More specifically, the complaint
challenged Cabletron's revenue recognition policies, accounting for product
returns, and the validity of some sales. The complaint does not specify the
amount of damages sought on behalf of the class. The plaintiffs served a second
consolidated class action complaint and Cabletron filed a motion to dismiss this
complaint. In a ruling dated May 23, 2001, the district court dismissed this
complaint with prejudice. The plaintiffs have appealed this ruling to the First
Circuit Court of Appeals. If the plaintiffs were to prevail on appeal, and
ultimately prevail on the merits of the case, Enterasys (formerly known as
Cabletron) could be required to pay substantial damages.

We have not assumed any liabilities from Enterasys for this litigation. We have
not been named as a defendant in this litigation and none of our officers or
directors is named as a defendant to this litigation. However, the plaintiffs
might attempt to involve us in this litigation or might seek to have us pay
damages if Enterasys has insufficient assets to cover any resulting damages. Any
involvement in this litigation could be protracted and may result in a diversion
of management and other resources. The payment of substantial legal costs or
damages, or the diversion of our management and other resources, could have a
material adverse effect on our business, financial condition or results of
operations.

On August 28, 2001, Tellabs Operations, Inc. filed an action against Riverstone
in the Chancery Division of the Circuit Court of Cook County, Illinois alleging
that Riverstone breached the Strategic Alliance Agreement dated as of November
17, 2000 between Riverstone and Tellabs and committed various torts by (i)
failing to provide Tellabls with CMTS products that met the technical
specifications in the agreement; (ii) misrepresenting to Tellabs the technical
capabilities of Riverstone's CMTS products; and (iii) improperly selling
Riverstone products to Tellabs customers. Tellabs' complaint seeks compensatory
damages in excess of $10 million, plus punitive damages and costs in unspecified
amounts. On that same date, Tellabs purported to terminate the agreement and is
seeking a declaratory judgment that it has no further obligations under the
agreement. We believe that Tellabs' claims are without merit and intend to
vigorously defend this proceeding. On August 29, 2001, Riverstone filed suit
against Tellabs in the Superior Court for Santa Clara County, California seeking
compensatory damages in excess of $60 million, including over $56 million in
unfulfilled minimum purchase obligations Tellabs was required to make under the
agreement. Riverstone has filed a motion in the Illinois case to have that
action dismissed or stayed, so that the parties' dispute can be heard in the
first instance in the California case.

We have granted options to purchase shares of our common stock under our 2000
equity incentive plan to our employees and employees of Cabletron and its
affiliates and to our advisors and consultants. As a result of the nature of the
persons who received these options and the vesting provisions of these options,
we may have violated the California state securities laws because we did not
qualify options granted prior to February 22, 2001 under California state
securities laws. Because these option grants were not qualified under California
state securities laws, persons residing in California who received these options
may have a claim against us. Accordingly, we currently intend to offer to
repurchase outstanding options to purchase shares of our common stock granted
under our 2000 equity incentive plan prior to February 22, 2001 to persons who
resided in California at the time of grant.

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

Item 2. Changes in Securities and Use of Proceeds

On February 16, 2001, in connection with the initial public offering of our
common stock, $0.01 par value, a Registration Statement on Form S-1 (No. 333-
45958) was declared effective by the Securities and Exchange Commission
registering 11,500,000 shares for an aggregate estimated maximum offering price
of $161,000,000. We expect to use the net proceeds of the offering for working
capital and for other general corporate purposes. We will use our working
capital to fund our operating expenses including our increased research and
development costs and the expansion of our sales and marketing force. We may use
a portion of the net proceeds to acquire complementary products, technologies or
businesses. However, we have no commitments or agreements for any specific
acquisitions and are not in negotiations for any acquisition transactions.

                                      25


Until the use of the net proceeds from our initial public offering as described
above, we plan to invest the net proceeds in short and long-term, investment
grade, interest bearing obligations.

Pursuant to an agreement between Cabletron and Riverstone, Riverstone issued
7,117,757 shares of its common stock to Cabletron in exchange for approximately
$122 million in cash and certain strategic investments valued at approximately
$13 million. This issuance was exempt from registration as a private offering
pursuant to Rule 4(2) of the Securities Exchange Act of 1934, as amended.

Item 3. Defaults Upon Senior Securities

None.

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

The Company held its Annual Meeting of Stockholders on July 31, 2001 to (i)

Equity Incentive Plan (Amended and Restated) to increase the number of shares
reserved under the plan to 50 million and to add an automatic share increase to
the plan, and adopt the plan as so amended and (iii) adopt the Company's
Employee Stock Purchase Plan.

At the Annual Meeting the preceding proposals were voted on with the following
results:

Item 5. Other Information

Pursuant to an agreement between Cabletron and Riverstone, in July 2001,
Riverstone received $1.5 million from Cabletron to release Cabletron from its
obligation to indemnify Riverstone for amounts paid or expenses incurred in
connection with Riverstone's proposed rescission offer.

On July 31, 2001, Riverstone's board of directors voted to remove the
restrictions on transfer of 2.5 million shares underlying options granted to
Messrs. Patel, Jaeger and Kirkpatrick.

On July 13, 2001, the Riverstone board of directors approved the adoption of a
stockholder rights plan. Under the plan, one right was issued for each share of
the Company's common stock outstanding on July 26, 2001. Stock issued after that
date will be issued with an attached right. Each right would initially represent
the right, under certain circumstances, to purchase 1/1000 of a share of a new
series of preferred stock of the Company at an exercise price of $115 per share.
