VISUAL NETWORKS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2002
(Unaudited)

1. Nature of Operations and Summary of Significant Accounting Policies:

Visual Networks, Inc. ("Visual" or the "Company") designs, manufactures,
sells and supports systems that manage the level of service provided over
telecommunications networks, including networks that support the Internet.

Risks and Other Important Factors

The Company incurred significant losses from the second quarter of 2000
through the fourth quarter of 2001. The deterioration of the Company's operating
results in 2000, excluding the effects of impairment and restructuring charges
and the write-off of in-process research and development ("IPR&D"), was due
primarily to decreased revenue and increased operating expenses compared to
1999. The Company made significant reductions in operating expenses in 2000,
2001 and 2002, including those resulting from the closure of three facilities
and the reduction of its workforce by approximately 270 employees from October
2000 through September 2002, approximately 40 of whom were terminated during the
nine months ended September 30, 2002.

Based on its current cost structure, the Company's ability to generate
operating income is, in large part, dependent on its success in achieving
quarterly revenue of at least $14.0 million to $15.0 million, achieving
quarterly gross margins of 70% to 75% and maintaining or further reducing
operating expenses. Due to market conditions, competitive pressures and other
factors beyond the Company's control, there can be no assurances that the
Company will be able to achieve these quarterly goals. In the event that the
Company does not realize anticipated cost reductions or achieve its revenue
goals, it may be required to further reduce its cost structure. While the
Company experienced its third consecutive quarter of profitability during the
three months ended September 30, 2002, there can be no assurance that the
Company will remain profitable.

The success of the Company is also dependent on its ability to generate
adequate cash for operating and capital needs. To meet its cash requirements,
the Company is relying on its existing cash and cash equivalents and the net
proceeds from the issuance of the convertible debentures (see Note 3), together
with future product sales and the collection of the related accounts receivable.
If cash provided by these sources is not sufficient to fund future operations,
the Company will be required to further reduce its operating expenditures or to
seek additional capital through other means including the sale of assets, the
sale of equity securities or additional borrowings. There can be no assurances
that additional capital will be available, or available on terms that are
reasonable or acceptable to the Company, particularly in light of the Company's
accumulated deficit position.

The Company's operations and financial position are subject to certain
risks and uncertainties including, among other things, its accumulated deficit,
uncertainty of future profitability and possible fluctuations in financial
results, substantial fixed operating costs, possible substantial dilution to
common stockholders as a result of the terms of its convertible debentures,
dependence on sales to key customers, including WorldCom, dependence on a
sole-source subcontract manufacturer, potential delisting and reduced liquidity
of its shares resulting from failure to meet Nasdaq listing requirements, the
potential triggering of early repayment of the debentures, the continued
downturn in the telecommunications industry, long sales cycles, improvements to
the infrastructure of the Internet, rapid technological change, growing
competition from several market segments, product errors, dependence upon sole
and limited source suppliers, potential fluctuations in component pricing,
potential claims of patent infringement by third parties, potential failure to
protect its intellectual property rights, dependence upon key employees, ability
to retain employees and the defense of a purported class action lawsuit. Failure
to meet any of these and other challenges could adversely affect the Company's
future operating results and financial condition.

Financial Statement Presentation

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, the
disclosure of contingent assets and liabilities at the date of statements and
the reported amounts of revenue and expenses during the reporting periods.
Actual results could differ from those estimates.

6


These financial statements are unaudited and have been prepared by the
Company pursuant to the rules and regulations of the Securities and Exchange
Commission regarding interim financial reporting. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements, and it is suggested
that these financial statements be read in conjunction with the financial
statements, and notes thereto, included in the Company's Annual Report on Form
10-K/A (Amendment No. 2) for the year ended December 31, 2001. In the opinion of
management, the comparative financial statements for the periods presented
herein include all adjustments that are normal and recurring which are necessary
for a fair presentation of results for the interim periods. The results of
operations for the nine months ended September 30, 2002 are not necessarily
indicative of the results that will be achieved for the entire year ending
December 31, 2002.

Principles of Consolidation

The consolidated financial statements include the accounts of Visual
Networks, Inc. and its wholly owned subsidiaries. All intercompany account
balances and transactions have been eliminated in consolidation.

Investments

The Company holds a certificate of deposit in the amount of $2.5 million
that matures on May 31, 2003. The certificate of deposit has been included as a
restricted short-term investment (see Note 2) in the accompanying consolidated
balance sheets as of December 31, 2001 and September 30, 2002. The certificate
of deposit is held by a bank to collateralize a $2.5 million letter of credit
issued in favor of one of the Company's contract manufacturers that expires on
September 30, 2003.

Inventory

Cost of revenue consists of subcontracting costs, component parts,
warehouse costs, direct compensation costs, warranty and other contractual
obligations, royalties, license fees and other overhead expenses related to the
manufacturing operations. Product cost of revenue includes both hardware and
software cost of revenue in the accompanying consolidated statements of
operations. Cost of revenue related to software sales has not been significant.
Support and services cost of revenue includes benchmark services, professional
services and technical support costs in the accompanying consolidated statements
of operations. Inventory is stated at the lower of average cost or market, and
consists of the following (unaudited, in thousands):

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

Revenue Recognition

The Company's performance management products and services include
hardware, software, professional services and technical support. In 2001, the
Company also provided benchmark services. Benchmark services, professional
services and technical support revenues are reported as service revenue in the
accompanying consolidated statements of operations. The Company recognizes
revenue from the sale or license of its products in accordance with the American
Institute of Certified Public Accountants Statement of Position No. 97-2,
"Software Revenue Recognition" and SEC Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements," which summarizes existing
accounting literature and require that four criteria are met prior to the
recognition of revenue. The Company's accounting policies regarding revenue
recognition are written to comply with the following criteria: 1) persuasive
evidence of an arrangement exists; 2) delivery has occurred or services have
been rendered; 3) the fees are fixed and determinable;

7


and 4) collectibility is probable. Where agreements provide for customer
acceptance, the Company recognizes revenue upon acceptance of the product by the
customer. Generally, the Company's agreements have not included any specific
customer acceptance provisions. However, the Company does allow some of its
customers to evaluate its products before making a decision to purchase. The
Company recognizes revenue under these arrangements once the evaluation process
is complete and all other criteria are met. Revenue from multiple-element
software arrangements is recognized using the residual method whereby the fair
value of any undelivered elements, such as customer support and services, is
deferred and any residual value is allocated to the software and recognized as
revenue upon delivery and passage of title. The fair values of professional
services, technical support and training have been determined based on the
Company's specific objective evidence of fair value. The Company's specific
objective evidence of fair value is based on the price the Company charges
customers when the service is sold separately.

Maintenance contracts require the Company to provide technical support and
unspecified software updates to customers on a when and if available basis. The
Company recognizes technical support revenue, including support revenue that is
bundled with product sales, ratably over the term of the contract period, which
generally ranges from one to three years. Revenue from professional services is
recognized when the services are performed. Subscription fees for the Company's
benchmark reports are recognized upon delivery of the reports.

The Company sells its products directly to service providers and end-user
customers, as well as through indirect channels. Certain reseller customers have
stock rotation rights, under which the customer can exchange previously
purchased products for other products of equal or greater cost, subject to
certain limitations, based on their end-user customers' requirements. The
Company recognizes revenue under these arrangements once the stock rotation
right expires or the product has been resold by the Company's master
distributor.

The Company examines the specific facts and circumstances of all sales
arrangements with payment terms extending beyond its normal payment terms to
make a determination of whether the sales price is fixed and determinable and
whether collectibility is probable. Payment terms are not tied to milestone
deliverables or customer acceptance. The evaluation of the impact on revenue
recognition, if any, includes the Company's history with its customers and the
specific facts of each arrangement. The Company generally does not offer payment
terms that differ from its normal payment terms.

The Company has agreements with certain service providers that provide
price protection in the event that more favorable prices and terms are granted
to any other similarly situated customer. When required, reserves for estimated
price protection credits are established by the Company concurrently with the
recognition of revenue. The Company monitors the factors that influence the
pricing of its products and service provider inventory levels and makes
adjustments to these reserves when management believes that actual price
protection credits may differ from established estimates.

In May 2001, the Company announced the discontinuation of the Visual
Trinity product. This product was the primary product acquired with Avesta, and
the Company stopped all development efforts on the Visual Trinity product in May
2001. The Company continued providing technical support for the Visual Trinity
product through September 2002 and has no remaining technical support
obligations to the Visual Trinity customers. As a result, revenue related to
this product subsequent to May 2001 consisted primarily of technical support
revenue, all of which was included in deferred revenue and recognized over the
terms of the relevant agreements.

In June 2001, the Company announced the sale of the Visual Internet
Benchmark service. The Company will continue to recognize revenue from the
Visual Internet Benchmark service for existing contracts, under which the
Company is still required to perform services through May 2003, most of which is
currently in deferred revenue. The Company receives royalty payments from the
purchaser on new contracts, which are included in support and services revenue
in the accompanying statement of operations for the three and nine months ended
September 30, 2002.

Credit Risk

Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of accounts receivable. The
Company generally sells its products to large telecommunications and Internet
service provider companies primarily in the United States. The Company grants
credit terms without collateral to its customers and, prior to the bankruptcy of
one of the Company's significant customers during the three months ended
September 30, 2002 as described below, has not experienced any significant
credit related losses. Accounts receivable include allowances to record
receivables at their estimated net realizable value. As of September 30, 2002,
one customer individually represented $4.0 million or 59% of accounts
receivable.

A significant customer of the Company, WorldCom, filed for bankruptcy on
July 21, 2002. WorldCom represented approximately

8


$12.3 million and $7.6 million in revenue for the years ended December 31, 2000
and 2001, respectively, and approximately $1.3 million, $2.3 million and $2.1
million in revenue for the three months ended March 31, 2002, June 30, 2002 and
September 30, 2002, respectively. The Company wrote off approximately $0.7
million of accounts receivables due from WorldCom against the allowance for bad
debts during the three months ended September 30, 2002. The allowance for bad
debts was $1.1 million as of June 30, 2002 and $0.4 million as of September 30,
2002. Any future recoveries of these written-off receivables will be recorded
when and if they are received.

Due to the relationship that the Company has with WorldCom and its
customers, the Company is continuing to sell products to WorldCom during its
bankruptcy. The Company has taken steps to limit its financial exposure. In July
2002, the Company signed an agreement (the "July Agreement") with WorldCom that
established new terms and conditions under which the Company conducted business
with WorldCom during the initial weeks of WorldCom's bankruptcy. After WorldCom
demonstrated timely payment of post-petition purchase orders, the Company
entered into a subsequent amendment (the "August Amendment") that changed
WorldCom's payment terms to substantially those that existed prior to the
bankruptcy filing. WorldCom was in compliance with the terms of the July
Agreement and August Amendment during the three months ended September 30, 2002
and continues to be in compliance as of November 13, 2002.

Income Taxes

The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes." Under SFAS No. 109, deferred tax assets and
liabilities are computed based on the difference between the financial statement
and income tax bases of assets and liabilities using the enacted marginal tax
rate. SFAS No. 109 requires that the net deferred tax asset be reduced by a
valuation allowance if, based on the weight of available evidence, it is more
likely than not that some portion or all of the net deferred tax asset will not
be realized.

Comprehensive Income

The Company reports comprehensive income in accordance with SFAS No. 130,
"Reporting Comprehensive Income," which establishes rules for the reporting and
display of comprehensive income and its components. SFAS No. 130 requires
foreign currency translation adjustments and the unrealized gains and losses on
marketable securities to be included in other comprehensive income. Because the
Company has not had any significant components of other comprehensive income,
the reported net income (loss) does not differ materially from comprehensive
income (loss) for the three and nine months ended September 30, 2001. During
2002, the Company converted operations for its Canadian subsidiary to U.S.
Dollars and recorded the translation gain in the accompanying consolidated
statement of operations, and as of September 30, 2002, the Company had no
operations denominated in foreign currency.

Segment Reporting and Significant Customers

SFAS No. 131, "Disclosure about Segments of an Enterprise and Related
Information," establishes standards for the way that public business enterprises
report information about operating segments in annual financial statements and
requires that these enterprises report selected information about operating
segments in interim financial reports. Management has concluded that the
Company's operations occur in one segment only based upon the information used
by management in evaluating the performance of the business. SFAS No. 131 also
establishes standards for related disclosures about products and services,
geographic areas and major customers. The revenue and assets of the Company's
foreign subsidiaries have not been significant. During the nine months ended
September 30, 2002, the Company closed its branch in France and began efforts to
close its subsidiary in Singapore. For the nine months ended September 30, 2001,
three customers individually represented 29%, 15% and 10% of revenue. For the
nine months ended September 30, 2002, three customers individually represented
35%, 12% and 12% of revenue. The agreements with the Company's significant
customers do not obligate these customers to make any minimum purchases from the
Company.

The following table presents the Company's revenue by product (unaudited,
in thousands):

During 2001, the Company discontinued development and sales efforts of
Visual Trinity and sold the Visual Internet Benchmark service. During 2001, the
Company began evaluating the Visual eWatcher product, which, to date, has not
generated significant revenue. The Company believes this product's web
performance management functionality may be valuable and is exploring
alternatives for this product.

Basic and Diluted Earnings (Loss) Per Share

SFAS No. 128, "Earnings Per Share," requires dual presentation of basic
and diluted earnings (loss) per share. Basic earnings (loss) per share includes
no dilution and is computed by dividing net income (loss) available to common
stockholders by the weighted-average number of common shares outstanding for the
period.

Diluted earnings (loss) per share includes the potential dilution that
could occur if securities or other contracts to issue common stock were
exercised or converted into common stock. Options and warrants to purchase
8,259,120 shares of common stock that were outstanding as of September 30, 2001
were not included in the computation of diluted loss per share for the three and
nine months ended September 30, 2001 as their effect would be anti-dilutive. The
treasury stock effect of options and warrants to purchase 8,789,713 shares of
common stock that were outstanding at September 30, 2002 are included in the

New Accounting Pronouncements

In June 2001, the Financial Accounting Standards Board (the "FASB") issued
SFAS No. 141, "Business Combinations," and SFAS No. 142, "Goodwill and Other
Intangible Assets." SFAS No. 141 prospectively prohibits the pooling of interest
method of accounting for business combinations initiated after June 30, 2001.
SFAS No. 142 requires companies to cease amortizing goodwill on December 31,
2001 that existed at June 30, 2001. Any goodwill resulting from acquisitions
completed after June 30, 2001 will also not be amortized. SFAS No. 142 also
establishes a new method of testing goodwill for impairment on an annual basis
or on an interim basis if an event occurs or circumstances change that would
reduce the fair value of a reporting unit below its carrying value. The Company
did not have any outstanding goodwill or other intangibles as of December 31,
2001 and September 30, 2002. The Company also did not have any goodwill during
2001. The adoption of SFAS No. 142 did not have a material effect on the
Company's financial position or results of operations.

In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligations." It requires an entity to recognize the fair value of a
liability for an asset retirement obligation in the period in which it is
incurred if a reasonable estimate of fair value can be made. If a reasonable
estimate of fair value cannot be made in the period the asset retirement
obligation is incurred, the liability shall be recognized when a reasonable
estimate of fair value can be made. This new standard is effective in the first
quarter of

10


2003. The Company does not believe that SFAS No. 143 will have a material effect
on the Company's financial position or results of operations.

In August 2001, the FASB issued SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets," which supersedes SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of." Though it retains the basic requirements of SFAS No. 121
regarding when and how to measure impairment loss, SFAS No. 144 provides
additional implementation guidance. SFAS No. 144 is effective in the first
quarter of 2002. The Company adopted SFAS No. 144 during the nine months ended
September 30, 2002 and the adoption did not have a material effect on the
Company's financial position or results of operations.

In August 2002, the FASB issued SFAS No. 146 "Accounting for Costs
Associated with Exit or Disposal Activities". It addresses financial accounting
and reporting for costs associated with exit or disposal activities and
nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, "Liability
Recognition for Certain Employee Termination Benefits and Other Costs to Exit an
Activity (including Certain Costs Incurred in a Restructuring)." SFAS No. 146
requires that a liability for a cost associated with an exit or disposal
activity be recognized when the liability is incurred and establishes that fair
value is the objective for initial measurement of the liability. Under EITF
Issue No. 94-3, a liability for an exit cost is recognized at the date of an
entity's commitment to an exit plan. The new standard is effective for exit or
disposal activities that are initiated after December 31, 2002, with early
adoption encouraged. The Company does not believe that SFAS No. 146 will have a
material effect on the Company's financial position or results of operations.

2. Credit Agreements and Long-Term Debt:

During 2001 through March 2002, the Company maintained a credit facility,
as amended, that included an accounts receivable-based arrangement providing for
borrowings up to the lesser of $10.0 million or 80% of eligible accounts
receivable (as defined in the credit facility and determined by the bank). The
bank credit facility included an equipment financing facility. During the six
months ended September 30, 2001, the Company borrowed approximately $0.5 million
to be repaid over 36 months under the equipment financing facility, of which
$0.4 million was outstanding as of December 31, 2001. As of December 31, 2001,
the Company also had approximately $1.7 million of borrowings outstanding at an
interest rate of 6.75% under the accounts receivable-based arrangement.. In
connection with the issuance of the convertible debentures (see Note 3), the
Company repaid the outstanding balance of the credit facility, and the related
loan agreements were terminated. As a result, the borrowings under the accounts
receivable-based and equipment financing arrangements were classified as current
in the accompanying consolidated balance sheet as of December 31, 2001.

In December 2000, the bank issued a standby letter of credit, as amended,
in favor of the Company's contract manufacturer, that expires on September 30,
2003 in the amount of $2.5 million. The Company secured the letter of credit
with a pledge of a certificate of deposit in the amount of $2.5 million that
expires on May 31, 2003, as amended, which is recorded as a restricted
short-term investment in the accompanying consolidated balance sheets as of
December 31, 2001 and September 30, 2002.

3. Convertible Debentures:

In March 2002, the Company issued senior secured convertible debentures in
the aggregate amount of $10.5 million in a private placement. The Debentures are
due March 25, 2006, are payable in common stock or cash, at the Company's option
provided certain conditions are satisfied, and bear interest at an annual rate
of 5% payable quarterly in common stock or cash, at the Company's option,
provided certain conditions are satisfied. The Debentures are secured by a first
priority lien on substantially all of the Company's assets. The Debentures may
be converted initially into 2,986,093 shares of the Company's common stock at
the option of the holders at a price of $3.5163 per share, subject to certain
adjustments. The conversion price of the Debentures will adjust if the Company
issues additional shares of common stock or instruments convertible into common
stock at a price that is less than the then-effective conversion price of the
Debentures. The Company has the right to require the holders to convert their
Debentures into common stock if the closing price of the Company's common stock
exceeds 175% of the conversion price for 20 consecutive days after September 26,
2003.

The Debentures include certain financial covenants related to earnings
before interest, taxes, depreciation and amortization, less capital
expenditures, for 2002 and 2003. If the financial covenants are not met, the
holders may cause the Company to redeem the Debentures at a price equal to the
principal amount of the Debentures plus accrued interest. The redemption may be
made in common stock or cash, at the Company's option, provided certain
conditions are satisfied. Cash redemption of the Debentures also may be required
upon a specified change of control or upon the occurrence of any one of the
other triggering events, including but not limited

11


to, default on other indebtedness and failure to maintain the common stock
listing on an eligible market. In the event that the financial covenant for 2002
is achieved, the first priority lien in favor of the debenture holders shall be
released.

In connection with the issuance of the Debentures, the Company issued to
the holders warrants to purchase 828,861 shares of its common stock at an
initial exercise price of $4.2755 per share. The exercise price will be adjusted
if the Company issues additional shares of common stock or instruments
convertible into common stock at a lower price than the then-effective exercise
price. The warrants expire on March 25, 2007.

The holders of the Debentures also received the right to purchase shares
of to-be-created Series A preferred stock (the "Preferred Stock Rights") at
certain dates in the future. The first Preferred Stock Right for 575 shares for
$5.8 million expired on May 6, 2002. The holders did not exercise the right to
purchase these shares of Series A preferred stock. A second Preferred Stock
Right for 307 shares for $3.1 million may be exercised at any time after
September 2002 but before June 2003. A third Preferred Stock Purchase Right for
170 shares for $1.7 million also expired on May 6, 2002. The holders also did
not exercise the right to purchase these shares of Series A preferred stock. The
Debenture holders were also granted certain equity participation and
registration rights.

Under the terms of the Debentures, a number of events could trigger the
Debenture holders' right to force early repayment of 115% of the outstanding
principal plus accrued and unpaid interest owed under the debentures. Events
constituting a triggering event include:

o default by the Company on other indebtedness or obligations under
any other debenture, mortgage, credit agreement or other facility,
indenture agreement, factoring agreement or other instrument under
which there may be issued, or by which there may be secured or
evidenced, any indebtedness for borrowed money or money due under
any long term leasing or factoring arrangement in an amount
exceeding $500,000;

o failure by the Company to have its common stock listed on an
eligible market;

o bankruptcy of the Company;

o engagement by the Company in certain change in control, sale of
assets or redemption transactions;

o failure by the Company to timely file its 2002 or 2003 annual
reports on Form 10-K; and

o certain other failures by the Company to perform obligations under
the Debenture agreement and/or the related agreements.

In addition, if the Company's earnings before interest, taxes,
depreciation and amortization, less capital expenditures, for the year ended
December 31, 2002 is less than $2.8 million, the Debenture holders may require
the Company to prepay all or a portion of up to 50% of the outstanding principal
amount of their Debentures. If the Company's earnings before interest, taxes,
depreciation and amortization, less capital expenditures, for the year ended
December 31, 2003 is less than $6.5 million, the Debenture holders may require
the Company to prepay all or a portion of up to 100% of the outstanding
principal amount of the Debentures.

If the Company does not have sufficient cash to repay these amounts if
required, the Company may be required to seek additional capital through a sale
of assets, sale of additional securities or through additional borrowings, none
of which may be available on terms reasonably acceptable to the Company.

The total Debentures of $10.5 million are included in the accompanying
balance sheet as of September 30, 2002, net of unamortized debt discount of
approximately $2.7 million, which represents the fair market value after
allocating the proceeds to the various additional components of the debt.
Approximately $2.1 million in proceeds from the Debentures were allocated to the
value of the warrants. The fair value of the warrants was determined using the
Black-Scholes valuation model with the following assumptions: no dividend yield,
expected volatility of 129%, risk-free interest rate of 4.85% and a term of five
years. Approximately $0.3 million in proceeds from the Debentures was allocated
to the value of the Preferred Stock Rights as determined by an appraisal. On the
date of issuance of the Debentures, the conversion price of the Debentures,
after taking into consideration the allocation of proceeds to the warrants and
Preferred Stock Rights, was less than the quoted market price of the Company's
common stock. Accordingly, approximately $1.0 million in proceeds from the
Debentures was allocated to additional paid-in capital to recognize this
beneficial conversion feature. The discount on the Debentures resulting from the
allocation of proceeds to the value of the warrants, Preferred Stock Rights and
beneficial conversion will be amortized as a charge to interest expense over the
four-year period until the Debentures become due in March 2006.

4. Commitments and Contingencies:

Litigation

In July, August and September 2000, several purported class action
complaints were filed against the Company and certain of the Company's former
executives (collectively, the "defendants"). These complaints have since been
combined into a single consolidated amended complaint (the "complaint"). The
complaint alleges that between February 7, 2000 and August 23, 2000, the
defendants made false and misleading statements, which had the effect of
inflating the market price of the Company's stock, in violation of Sections
10(b) and 20(a) of the Securities Exchange Act of 1934. On August 20, 2002,
United States District Judge Deborah K. Chasanow entered an order in the United
States District Court for the District of Maryland dismissing the complaint. On
September 17, 2002, the plaintiffs appealed the District Court's decision to the
United States Court of Appeals for the Fourth Circuit. The complaint does not
specify the amount of damages sought. The Company believes that the plaintiffs'
claims are without merit and intends to defend against these allegations
vigorously. The Company expects that a substantial portion of the legal costs
that it has incurred and may continue to incur related to this matter will be
paid by its directors' and officers' insurance policy. The Company cannot
presently determine the ultimate outcome of this action. A negative outcome
could have a material adverse effect on the Company's financial position or
results of operations. Failure to prevail in the litigation could result in,
among other things, the payment of substantial monetary damages in excess of any
amounts paid by the Company's directors' and officers' insurance. The Company
has not recorded any liability related to this matter in the accompanying
balance sheets as of December 31, 2001 and September 30, 2002.

The Company is periodically a party to disputes arising from normal
business activities including various employee-related matters. In the opinion
of management, resolution of these matters will not have a material adverse
effect upon the Company's financial position or future operating results.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Overview

From our incorporation in August 1993 through December 1996, our principal
objective was to secure sufficient equity financing to enable us to accelerate
product development efforts of Visual UpTime for frame relay deployment and
create the infrastructure necessary to support these efforts. We first shipped
Visual UpTime in mid-1995 and began generating significant revenue during 1996.
Since our inception, we have focused on establishing relationships with service
providers with the goal of having these service providers include our products
into their infrastructure or in their service offerings to their subscribers.
Consistent with this goal, we have established agreements with AT&T, Equant,
Sprint and WorldCom. During 1998, 1999 and 2000, we continued to focus on
selling Visual UpTime, and added to the following products: the Net2Net product,
Cell Tracer, in 1998; the Inverse products, Visual IP InSight and Visual
Internet Benchmark, in 1999; and the Avesta products, Visual Trinity and Visual
eWatcher, in 2000. During 2001, we discontinued development and sales efforts of
Visual Trinity and sold the Visual Internet Benchmark service. During 2001, we
began evaluating our Visual eWatcher product, which, to date, has not generated
significant revenue. We believe the web performance management functionality of
this product may be valuable, and we are exploring alternatives for this
product. During the nine months ended September 30, 2002, we amended our
agreement with Network Associates, Inc. (NAI) for the Cell Tracer product so
that NAI received the source code for the Visual Cell Tracer product to allow it
to support and modify the product. As a result of decreased demand from NAI, we
anticipate that NAI will place final orders with us by early 2003, and we do not
anticipate any significant revenue from the sale of this product to other
customers. In addition to final orders placed by NAI, we expect to recognize
approximately $1.5 million from deferred revenue as certain NAI stock rotation
rights expire. We continue to focus on sales of Visual UpTime and Visual IP
InSight. In response to these events, we have revised our business plan to
reflect lower projected revenues and reduced our operating expenses to a level
that we believe is sufficient to allow us to remain profitable if we are able to
achieve revenues of $14.0 million to $15.0 million each quarter and meet our
target operating margins.

We acquired Avesta Technologies on May 24, 2000. We believed that the
acquisition of Avesta would provide critical pieces to our articulated strategy
to become one of the largest network performance management vendors with one of
the industry's broadest portfolios of products and functionality. We also
anticipated that the merger would bring us closer to providing a single-vendor
solution to the internet infrastructure management needs of customers,
especially the integration of networks, systems and applications into a unified
service view for service providers and their enterprise subscribers. We expected
to generate revenue from the Avesta products of approximately $30 million in
2000. Instead, these products generated revenues of only $7.3 million in 2000,
and significantly increased our operating expenses. Subsequent to the
acquisition, we concluded that, without significant modifications, the primary
Avesta product, Trinity, was not a viable solution for our strategic service
provider customers. The product was more specifically targeted to direct
enterprise customers, which did not fit with our service provider focused
business plan. As a result of an analysis performed by a company-wide task
force, we determined that the time and expense required to make the Visual
Trinity product competitive in its market space and more suitable to our service
provider customers would be prohibitive. These factors, in conjunction with
revenue declines in our other products, resulted in a $328.8 million impairment
charge and $7.0 million in restructuring charges in 2000. In 2001, we
discontinued the Visual Trinity product, resulting in $3.3 million in additional
impairment charges related to the remaining intangible assets from the Avesta
acquisition, $3.7 million in a write down related to an investment that was
acquired with Avesta that was determined to be impaired as of December 31, 2001
and $2.3 million (net of reversals) in restructuring charges. We did not have
any significant remaining assets related to Avesta included in our balance sheet
as of December 31, 2001 or September 30, 2002.

Following the acquisition of Avesta, we allowed our business strategy to
become less focused, which increased the complexity of our business and
adversely affected our results of operations. We incurred significant losses
from the second quarter of 2000 through the fourth quarter of 2001. The
deterioration of our operating results that began in 2000, excluding the effects
of the impairment and restructuring charges and the write-off of in-process
research and development, was due primarily to decreased revenue and increased
operating expenses following the Avesta acquisition. In response, we made
significant reductions in operating expenses in the remainder of 2000, 2001 and
2002 resulting from the closure of three facilities and the reduction of our
workforce by approximately 270 employees from October 2000 through September
2002, including approximately 40 of whom were terminated during the nine months
ended September 30, 2002.

We returned to profitability for the three months ended March 31, 2002 and
have remained profitable since then. However, we have continued to experience
declining revenue from $56.9 million for the nine months ended September 30,
2001 to $46.7 million for the nine months ended September 30, 2002, including a
reduction in the sale of each of our major products. The decrease included $1.2
million in revenue from the Cell Tracer product, which consisted almost entirely
of reduced demand from NAI. Visual UpTime revenue decreased by $3.6 million
reflecting: 1) the overall downturn in the telecommunications industry, which
was reflected in a

14


slowdown in demand for telecommunications products and services, including those
based on our products and 2) tighter inventory control at our service provider
customers, specifically AT&T. Revenue from the Visual IP InSight product
decreased $0.2 million resulting from both the bankruptcies of many of the new
Internet Service Providers that were our primary targets for Visual IP InSight,
and the events of September 11, 2001, which caused a slowdown in acquisition and
deployment of telecommunications products and services, including those based on
Visual IP InSight. In addition, revenue from the Visual IP InSight product often
fluctuates significantly from quarter to quarter due to the sizeable orders from
a limited number of service providers that we are dependent upon for that
product. Such fluctuations can also significantly affect our gross margin
percentage because our software costs of revenue are so insignificant. The $5.7
million decrease in revenue from Visual eWatcher, Visual Internet Benchmark and
Visual Trinity reflects, respectively, the reduced sales and marketing focus on
Visual eWatcher as we evaluate prospects for that technology, the sale of Visual
Internet Benchmark and the discontinuation of sales of Visual Trinity.

Based on our current cost structure, our ability to generate operating
income in the future is, in large part, dependent on our success in achieving
quarterly revenue of at least $14.0 million to $15.0 million, achieving
quarterly gross margins of 70% to 75% and maintaining or further reducing
operating expenses. Due to market conditions, competitive pressures, and other
factors beyond our control, there can be no assurances that we will be able to
meet these goals. In the event that the anticipated revenue goals are not met,
we may be required to further reduce our cost structure.

We have addressed those factors that have caused revenue to decline and
that are within our control. We have refocused our sales, marketing and other
efforts on our core Visual UpTime and Visual IP InSight products and our core
service provider customers. We have directed our Visual IP InSight development
efforts at making the product more suitable for our core service provider
customers and enabling the use of our product in higher-margin broadband
networks over, for example, cable lines and Digital Subscriber Lines (DSL). We
have also aggressively reduced our operating expenses to be more in line with
our reduced revenue projections. While we do not know when the downturn in
telecommunications industry will end, or how robust the recovery will be once or
if it does begin, we have revised our business plan to reflect lower projected
revenues and reduced our operating expenses as we seek to remain profitable even
with this reduced demand. There can be no assurance that we will remain
profitable.

Our business may be adversely affected by WorldCom's bankruptcy. WorldCom,
one of our significant customers, filed for bankruptcy on July 21, 2002.
WorldCom represented $12.3 million and $7.6 million of our revenue for the years
ended December 31, 2000 and 2001, respectively, and $1.3 million, $2.3 million
and $2.1 million of our revenue for the three months ended March 31, 2002, June
30, 2002 and September 30, 2002, respectively. As of June 30, 2002, WorldCom
owed us approximately $1.3 million. We received a subsequent payment from
WorldCom prior to bankruptcy for approximately $0.7 million. The remaining
accounts receivable balance of approximately $0.7 million was written off
against the allowance for bad debts during the three months ended September 30,
2002. The allowance for bad debts was $1.1 million as of June 30, 2002 and $0.4
million as of September 30, 2002. Any future recoveries of these written-off
receivables will be recorded when and if they are received.

Due to the relationship that we have with WorldCom and its customers, we
are continuing to sell products to WorldCom during its bankruptcy. We have taken
steps to limit our financial exposure. In July 2002, we signed an agreement (the
"July Agreement") with WorldCom that established new terms and conditions, under
which we conducted business with WorldCom during the initial weeks of WorldCom's
bankruptcy. After WorldCom demonstrated timely payment of post-petition purchase
orders, we entered into a subsequent amendment (the "August Amendment") that
changed WorldCom's payment terms to substantially those that existed prior to
the bankruptcy filing. WorldCom was in compliance with the terms of the July
Agreement and August Amendment during the three months ended September 30, 2002
and continues to be in compliance as of November 13, 2002.

We face risks of delayed orders from another significant customer, Equant,
due to its slower than expected deployment of our products. Equant represented
$3.0 million, or 6.4%, of revenue for the nine months ended September 30, 2002.
Due to the slower deployment, revenue from this customer may be reduced for the
remainder of 2002.

Our business may also be impacted if we continue to fail to comply with
Nasdaq listing standards. We recently moved the trading of our common stock to
the Nasdaq Small Cap Market. To maintain the listing on this market, we are
required to meet certain listing requirements, including a minimum bid price of
$1.00 per share. If our stock price closes below the minimum bid price of $1.00
for 30 consecutive trading days, we would receive a deficiency notice and,
assuming we continue to satisfy the other Nasdaq listing requirements, would
have a grace period of 180 calendar days to cure the deficiency by meeting the
minimum closing bid price per share trading price for 10 consecutive trading
days. Even if we are able to comply with the minimum bid requirement, there is
no assurance that in the future we will continue to satisfy the other Nasdaq
listing requirements, with the result that our common stock may be delisted.
Should our common stock be delisted from the Nasdq Small Cap Market, it would
likely be traded on the so-called "pink sheets" or the "Electronic Bulletin
Board" maintained by the National Association of Securities Dealers, Inc.
Consequently, it

15


would likely be more difficult to trade in or obtain accurate quotations as to
the market price of our common stock. Furthermore, if we are no longer listed on
the Nasdaq Small Cap Market, our $10.5 million of outstanding debentures may be
accelerated and become immediately due and payable upon demand by the debenture
holders.

During the three months ended September 30, 2002, we accepted the
resignations of our President and Chief Executive Officer, Elton King, and our
Vice-President and Chief Financial Officer, John Saunders. The Board of
Directors appointed Peter Minihane as our interim President and Chief Executive
Officer. Mr. Minihane is also serving as our principal financial officer until
we find a new Chief Financial Officer. We are actively searching for a permanent
President and Chief Executive Officer and Chief Financial Officer. Because Mr.
Minihane was our Executive Vice-President, Chief Financial Officer and Treasurer
until January 2002 and has subsequently been a very active member of the Board
of Directors, we do not expect these management changes to impact our future
operations. Also during this period, Michael Cassity and Marc Benson resigned
from our Board of Directors. We are actively seeking new board members.

The manufacture of our products is primarily completed by a sole-source
manufacturer. We have entered into negotiations with a second contract
manufacturer to mitigate our risk of relying on our sole-source manufacturer.
The agreement with the second manufacturer is not complete as of the date of
this filing. Until the agreement with the second contract manufacturer is
complete, an unanticipated interruption or delay in the scheduled receipt of
products from our sole source contract manufacturer could reduce revenue.

Revenues from one of our major customers, Sprint, declined $4.5 million,
to $3.8 million for the nine months ended September 30, 2002 from $8.3 million
for the nine months ended September 30, 2001. We believe that the reduction in
Sprint revenue was the result of a loss of market share of Sprint to its
competitors coupled with our loss of business to competitors. The recent events
at WorldCom did not have a significant impact on revenue from WorldCom for the
nine months ended September 30, 2002. However, there is a risk that these events
could affect our future revenue.

Our primary sales and marketing strategy depends predominantly on sales to
telecommunications service providers. Aspects of our service provider deployment
strategy depend on the sale of Visual UpTime and Visual IP InSight to service
providers for use as operations tools in their own network infrastructures. In
addition, our service provider deployment strategy depends on the sale of Visual
UpTime and Visual IP InSight to service providers for resale and as the basis
for value-added services to their customers. on the reductions of capital
expenditures and the decline in the telecommunications markets may delay the
roll-out of new services based on our products. Furthermore, any potential
reduction in demand for value added services or products from the service
providers' customers would directly impact the volume of our products purchased.

We expect that a significant portion of our revenue during the remainder
of 2002 will be attributable to sales of Visual UpTime and Visual IP InSight to
service providers. The loss of any one of AT&T, Equant, Sprint or WorldCom,
which together have historically provided a majority of our revenue, would
result in a substantial loss of revenue that could have a material adverse
effect on our business. WorldCom posted losses in their most recent quarterly
reports, which coupled with WorldCom's bankruptcy, have created uncertainty
about potential changes in the buying habits of this key customer. Existing
service provider customers are not easily replaced because of the relatively few
participants in that market. High barriers to entry due to extraordinary capital
requirements and the increased potential that existing service providers may
merge or fail because of the current downturn in the telecommunications industry
may further reduce their number, and would make replacing a significant service
provider customer very difficult. Furthermore, our small number of service
provider customers means that the reduction, delay or cancellation of orders or
a delay in shipment of our products to any one service provider customer could
have a material adverse effect on our revenue for a quarter. Our anticipated
dependence on sizable orders from a limited number of service providers will
make the relationship between us and each service provider critically important
to our business. We currently have contracts with all of our material customers
and such contracts generally have automatic renewal provisions. Further, because
none of our agreements contain minimum purchase requirements, there can be no
assurance that the issuance of a purchase order will result in significant
recurring business. There can be no assurance that our customers will not elect
to terminate and renegotiate these contracts seeking more favorable terms.

Our operations and financial position are subject to certain other risks
and uncertainties, including among others, our accumulated deficit, uncertainty
of future profitability and possible fluctuations in financial results,
substantial fixed operating costs, possible dilution to our common stockholders
due to the conversion features of our convertible debentures, dependence on
sales to key customers, dependence on WorldCom as a significant customer,
dependence on a sole-source subcontract manufacturer, potential delisting and
reduced liquidity of our shares resulting from failure to meet Nasdaq listing
requirements, the potential triggering of early repayment of our debentures, the
continued downturn in the telecommunications industry, long sales cycles,
improvements to the infrastructure of the Internet, rapid technological change,
growing competition from several market segments, errors in our products,
dependence upon sole and limited source suppliers, potential fluctuations in
component pricing, potential claims of patent infringement by third parties,
potential failure to protect our intellectual property rights, dependence upon
key employees, ability to retain employees and the defense of a purported class
action lawsuit. Failure to meet any of these and other challenges could
adversely affect our future operating results.

Results of Operations for the Three Months Ended September 30, 2002 Compared
with the Three Months Ended September 30, 2001

Revenue

Our revenue can be divided into three types: hardware, software and
support and services. Each of our products has components of each revenue type.
Sales of Visual UpTime are primarily classified as hardware revenue. We also
sell licenses related to Visual UpTime that are classified as software revenue.
Sales of Cell Tracer are classified as hardware revenue. Sales of Visual IP
InSight are primarily classified as software revenue. However, sales of our
newest hardware product, the ISE, which embeds certain Visual IP InSight
functionality in a hardware device, are classified as hardware revenue. Sales of
our Visual IP InSight subscription service, which we no longer offer to our
customers, were classified as support and services revenue. Sales of Visual
eWatcher are classified as software revenue. Sales of Visual Trinity, prior to
discontinuation in May 2001, were classified as software revenue. Sales of the
Visual Internet Benchmark service, prior to sale of that product in June 2001,
were classified as support and services revenue. Royalties from the Visual
Internet Benchmark service are classified as support and services revenue. Sales
of technical support, professional services and training for all of our products
are classified as support and services revenue.

Total revenue was $19.2 million for the three months ended September 30,
2001 compared to $14.7 million for the three months ended September 30, 2002, a
decrease of $4.5 million primarily from Sprint due to loss of Sprint market
share to competitors and our loss of business to competitors. Sales to all
service providers increased from approximately 77% of revenue for the three
months ended September 30, 2001 to 79% for the three months ended September 30,
2002. We anticipate that the percentage of revenue attributable to our service
providers for the remainder of 2002 will be consistent with the levels achieved
during the three months ended September 30, 2002.

Hardware revenue. Hardware revenue was $12.7 million for the three months
ended September 30, 2001 compared to $12.0 million for the three months ended
September 30, 2002, a decrease of $0.7 million. The overall decrease was due to
decreased demand for Cell Tracer. The decrease in Cell Tracer revenue of $0.7
million, from one customer, NAI was attributable to reduced demand from NAI. We
anticipate that NAI will place final orders with us by early 2003, and we do not
anticipate any significant revenue from the sale of this product to other
customers. In addition to final orders placed by NAI, we expect to recognize
approximately $1.5 million from deferred revenue as certain NAI stock rotation
rights expire. Revenue from Visual UpTime increased by $0.5 million from the
three months ended September 30, 2001 to the three months ended September 30,
2002 despite the decrease in Sprint revenue of $1.4 million. We believe the
reduction in Sprint revenue was the result of a loss of market share of Sprint
to its competitors coupled with our loss of business to competitors, which was
offset by increases in revenue from AT&T and WorldCom of $0.9 million and $0.6
million, respectively. The recent events at WorldCom did not have a significant
impact on revenue from WorldCom for the three months ended September 30, 2002.
However, there is a risk that WorldCom's bankruptcy could have an impact on our
future revenue.

Software revenue. Software revenue was $3.2 million for the three months
ended September 30, 2001 compared to $0.1 million for the three months ended
September 30, 2002, a decrease of $3.1 million. The decrease was primarily due
to a decrease in demand for Visual IP InSight.

Support and services revenue. Support and services revenue was $3.3
million for the three months ended September 30, 2001 and $2.5 million for the
three months ended September 30, 2002, a decrease of $0.8 million. The decrease
in support and services revenue was primarily attributable to decreased revenue
from support of the Visual Trinity product of $0.5 million and Visual Internet
Benchmark of $0.7 million due to expired contracts that have not renewed as a
result of the discontinuation of these products during the three months ended
September 30, 2001. Since September 30, 2001, we sell Visual IP InSight as a
software license only. Prior to September 30, 2001, we offered both a
subscription service and a software license for that product. Subscription fees
for Visual IP InSight decreased by $0.4 million as customers have migrated to a
perpetual license for that product. These decreases are partially offset by
increased technical support revenue for Visual IP InSight and the larger
installed base of our Visual UpTime product for which we are selling technical
support. We will continue to recognize revenue from the Visual Internet
Benchmark service that was sold during 2001, for existing contracts under which
we are still required to perform services through May 2003, most of which is
currently in deferred revenue. We also receive royalty payments from the
purchaser on new contracts. All of the remaining deferred revenue related to
technical support of the Visual Trinity product has been recognized as of
September 30, 2002. We will not have any additional revenue from the Visual
Trinity product in the future.

Cost of revenue and gross profit

Cost of revenue consists of subcontracting costs, component parts,
warehouse costs, direct compensation costs, communication costs, warranty and
other contractual obligations, royalties, license fees and other overhead
expenses related to manufacturing operations and support of our software
products and benchmark services.

Total cost of revenue was $7.1 million for the three months ended
September 30, 2001 compared to $4.4 million for the three months ended September
30, 2002, a decrease of $2.7 million. Gross profit was $12.1 million for the
three months ended September 30, 2001 compared to $10.2 million for the three
months ended September 30, 2002, a decrease of $1.9 million. Gross profit margin
was 63.0% of revenue for the three months ended September 30, 2001 as compared
to 69.9% of revenue for the three months ended September 30, 2002. The increase
in gross profit margin percentage was primarily attributable to the overall high
margin of our new Visual UpTime 7.0 and 7.1 releases, decreased lower margin
Cell Tracer revenue, decreased fixed costs such as fees paid to third parties to
provide the Visual IP InSight subscription service and Visual Internet Benchmark
service to customers for which we had existing contracts and overall decreased
fixed costs in our manufacturing and support operations due to our cost
reduction initiatives being implemented since the fourth quarter of 2000. Our
future gross margins may be affected by a number of factors, including product
mix, the proportion of sales to service providers, competitive pricing,
manufacturing volumes and an increase in the cost of component parts. Based on
our current product offerings and the level of fixed cost reductions that has
been achieved to date, we expect our future margins to be in the range of 70% to
75%.

Product cost of revenue. Product cost of revenue, which includes both
hardware and software cost of revenue, was $5.3 million for the three months
ended September 30, 2001 compared to $4.1 million for the three months ended
September 30, 2002, a decrease of $1.2 million. Our software costs of revenue
are insignificant. The gross profit margin attributable to products was 66.7%
for the three months ended September 30, 2001 and September 30, 2002. The gross
profit margin remained flat even though we had a significant decrease in
software revenue, which was $3.2 million for the three months ended September
30, 2001 compared to $0.1 million for the three months ended September 30, 2002.
This decrease is partially offset by the overall high margin of our new Visual
UpTime 7.0 and 7.1 releases, decreased low margin Cell Tracer revenue and
overall decreased fixed costs in our manufacturing and support operations due to
our cost cutting initiatives being implemented since the fourth quarter of 2000.

Support and services cost of revenue. Support and services cost of
revenue, which includes Visual Internet Benchmark services, Visual IP InSight
subscription services, professional services and technical support costs, was
$1.8 million for three months ended September 30, 2001 compared to $0.4 million
for the three months ended September 30, 2002, a decrease of $1.4 million. The
gross profit margin attributable to support and services was 45.5% for the three
months ended September 30, 2001 and 85.5% for the three months ended September
30, 2002. The increase in gross profit margin was primarily due to decreased
fixed costs such as fees paid to third parties to provide the Visual IP InSight
subscription service and Visual Internet Benchmark service to customers for
which we had existing contracts.

Research and development expense. Research and development expense
consists of compensation for research and development staff, depreciation of
test and development equipment, certain software development costs and costs of
prototype materials. Research and development expense was $4.6 million for the
three months ended September 30, 2001 compared to $3.1 million for the three
months ended September 30, 2002, a decrease of $1.5 million. The decrease in
research and development expense was due primarily to the full period effect of
workforce reductions and facility closures during 2001 and additional workforce
reductions during 2002. Research and development expense was 23.7% and 20.9% of
revenue for the three months ended September 30, 2001 and 2002, respectively.
For the remainder of 2002, we intend to incur research and development expense
at or below the level of such expense in the third quarter of 2002 as a result
of our continued focus on the control of operating expenses.

Sales and marketing expense. Sales and marketing expense consists of
compensation for the sales and marketing staff, commissions, pre-sales support,
travel and entertainment expense, trade shows and other marketing programs.
Sales and marketing expense was $8.4 million for the three months ended
September 30, 2001 compared to $4.5 million for the three months ended September
30, 2002, a decrease of $3.9 million. The decrease in sales and marketing
expense was due primarily to the full period effect of workforce reductions and
facility closures during 2001 and 2002. Sales and marketing expense was 43.8%
and 31.0% of revenue for the three months ended September 30, 2001 and 2002,
respectively. For the remainder of 2002, we intend to incur sales and marketing
expense at or below the level of such expense in the third quarter of 2002 as a
result of our continued focus on the control of operating expenses.

General and administrative expense. General and administrative expense
consists of the costs of executive management, finance, administration and other
activities. General and administrative expense was $2.1 million for the three
months ended September 30, 2001 compared with $1.6 million for the three months
ended September 30, 2002, a decrease of $0.5 million. The decrease in general

19


and administrative expense was due primarily to the full period effect of
workforce reductions and facility closures during 2001 and additional workforce
reductions during 2002. General and administrative expense was 11.0% and 11.0%
of revenue for the three months ended September 30, 2001 and 2002, respectively.
For the remainder of 2002, we intend to incur general and administrative expense
at or below the level of such expense in the third quarter of 2002 or decrease
them in absolute dollars during 2002 as a result of our continued focus on the
control of operating expenses.

Amortization of acquired intangibles. We recorded $13,000 in amortization
of goodwill and other intangibles during the three months ended September 30,
2001 related to the Avesta acquisition. All amounts of goodwill and other
intangible assets were amortized or written-off as of December 31, 2001.
Therefore, no amortization was recorded during the three months ended September
30, 2002.

Interest income (expense), net. Interest income, net, was $10,000 for the
three months ended September 30, 2001 compared to expense of $0.4 million for
the three months ended September 30, 2002. The decrease of $0.4 million was
primarily due to both cash and non-cash interest expense related to the
convertible debentures we issued in March 2002 (see Note 3).

Net income (loss). Net loss for the three months ended September 30, 2001
was $3.0 million as compared to net income of $0.7 million for the three months
ended September 30, 2002, an increase in income of $3.7 million. The increase
was due primarily to decreases in cost of sales and operating expenses offset by
decreased revenue.

Results of Operations for the Nine Months Ended September 30, 2002 Compared with
the Nine Months Ended September 30, 2001

Revenue

Total revenue was $56.9 million for the nine months ended September 30,
2001 compared to $46.7 million for the nine months ended September 30, 2002, a
decrease of $10.2 million. Sales to all service providers increased from
approximately 80% of revenue for the nine months ended September 30, 2001 to 85%
for the nine months ended September 30, 2002.

Hardware revenue. Hardware revenue was $39.4 million for the nine months
ended September 30, 2001 compared to $31.9 million for the nine months ended
September 30, 2002, a decrease of $7.5 million. The overall decrease was due
primarily to decreased demand for Visual UpTime and Cell Tracer. The decrease in
Cell Tracer revenue of $1.2 million, from NAI, was attributable to reduced
demand. The decrease in sales of Visual UpTime, primarily from service providers
and value-added resellers, of $3.6 million was primarily attributable to a
decrease in purchases from Sprint of $4.5 million. We believe the reduction in
Sprint revenue was the result of a loss of market share of Sprint to its
competitors coupled with our loss of business to competitors. The recent events
at WorldCom did not have a significant impact on revenue from WorldCom for the
three months ended September 30, 2002. However, there is a risk that WorldCom's
bankruptcy could have an impact on our future revenue.

Software revenue. Software revenue was $4.5 million for the nine months
ended September 30, 2001 compared to $5.2 million for the nine months ended
September 30, 2002, an increase of $0.7 million. A significant sale of Visual IP
Insight to Verizon resulted in $3.5 million of the $5.2 million total software
revenue during the nine months ended September 30, 2002. This sale is the
primary source of the increase. This increase is partially offset by a decrease
in revenue from the Visual Trinity product, the primary product acquired from
Avesta, resulting from the discontinuation of that product.

Support and services revenue. Support and services revenue was $13.0
million for the nine months ended September 30, 2001 and $9.6 million for the
nine months ended September 30, 2002, a decrease of $3.4 million. The decrease
in support and services revenue was primarily attributable to decreased revenue
from the Visual Trinity product and Visual Internet Benchmark due to expired
contracts that have not renewed as a result of the discontinuation of these
products during the three months ended September 30, 2001. Subscription fees for
Visual IP InSight decreased by approximately $1.6 million as customers have
migrated to a perpetual license for that product. Since September 30, 2001, we
sell Visual IP InSight as a software license only. Prior to September 30, 2001,
we offered both a subscription service and a software license for that product.
These combined decreases are offset by the larger installed base of our Visual
UpTime product for which we are selling technical support.

Cost of revenue and gross profit

Total cost of revenue was $23.4 million for the nine months ended
September 30, 2001 compared to $13.0 million for the nine months ended September
30, 2002, a decrease of $10.4 million. Gross profit remained flat at $33.6
million for the nine months ended

20


September 30, 2001 and 2002. Gross profit margin was 59.0% of revenue for the
nine months ended September 30, 2001 as compared to 72.0% of revenue for the
nine months ended September 30, 2002.

Product cost of revenue. Product cost of revenue was $17.1 million for the
nine months ended September 30, 2001 compared to $11.4 million for the nine
months ended September 30, 2002, a decrease of $5.7 million. Our software costs
of revenue are insignificant. The gross profit margin attributable to products
was 61.1% for the nine months ended September 30, 2001 and 69.4% for the nine
months ended September 30, 2002. The increase in gross profit margin was
primarily attributable to a significant high margin Visual IP InSight sale, the
overall high margin of our new Visual UpTime 7.0 and 7.1 releases, decreased low
margin Cell Tracer revenue and overall decreased fixed costs in our
manufacturing and support operations due to our cost cutting initiatives.

Support and services cost of revenue. Support and services cost of revenue
was $6.3 million for nine months ended September 30, 2001 compared to $1.7
million for the nine months ended September 30, 2002, a decrease of $4.6
million. The gross profit margin attributable to support and services was 51.8%
for the nine months ended September 30, 2001 and 82.4% for the nine months ended
September 30, 2002. The increase in gross profit margin was primarily due to
decreased fixed costs such as fees paid to third parties to provide the Visual
IP InSight subscription service and Visual Internet Benchmark service to
customers for which we had existing contracts.

Research and development expense. Research and development expense was
$15.7 million for the nine months ended September 30, 2001 compared to $9.5
million for the nine months ended September 30, 2002, a decrease of $6.2
million. The decrease in research and development expense was due primarily to
the full period effect of workforce reductions and facility closures during 2001
and additional workforce reductions during 2002. Research and development
expense was 27.6% and 20.4% of revenue for the nine months ended September 30,
2001 and 2002, respectively.

Sales and marketing expense. Sales and marketing expense was $27.0 million
for the nine months ended September 30, 2001 compared to $15.7 million for the
nine months ended September 30, 2002, a decrease of $11.3 million. The decrease
in sales and marketing expense was due primarily to the full period effect of
workforce reductions and facility closures during 2001 and 2002. Sales and
marketing expense was 47.5% and 33.7% of revenue for the nine months ended
September 30, 2001 and 2002, respectively.

General and administrative expense. General and administrative expense was
$7.1 million for the nine months ended September 30, 2001 compared with $5.4
million for the nine months ended September 30, 2002, a decrease of $1.7
million. The decrease in general and administrative expense was due primarily to
the full period effect of workforce reductions and facility closures during 2001
and additional workforce reductions during 2002 offset by the bad debt expense
of $0.5 million recorded to cover our financial exposure from WorldCom. General
and administrative expense was 12.5% and 11.5% of revenue for the nine months
ended September 30, 2001 and 2002, respectively.

Restructuring and impairment charges. We reversed approximately $0.7
million of prior period restructuring charges in the nine months ended September
30, 2001. The reversal resulted primarily from the lower than estimated costs
related to facility closings. We recorded a restructuring charge in the nine
months ended September 30, 2001 in the amount of $3.9 million related primarily
to a workforce reduction of approximately 50 employees and the closure of our
New York facility as a result of the discontinuation of the Visual Trinity
product. We recorded an impairment charge of $3.1 million in the nine months
ended September 30, 2001 for the write-off of intangible assets related to the
Avesta acquisition. There have been no restructuring or impairment charges in
2002. Costs associated with the workforce reductions in 2002 have been charged
to operating expenses as incurred.

Amortization of acquired intangibles. We recorded $0.8 million in
amortization of goodwill and other intangibles during the nine months ended
September 30, 2001 related to the Avesta acquisition. All amounts of goodwill
and other intangible assets were amortized or written-off as of December 31,
2001. Therefore, no amortization was recorded during the nine months ended
September 30, 2002.

Interest income (expense), net. Interest income, net, was $0.4 million for
the nine months ended September 30, 2001 compared to expense of $0.8 million for
the nine months ended September 30, 2002. The decrease of $1.2 million was
primarily due to both cash and non-cash interest expense related to the
convertible debentures we issued in March 2002 (see Note 3) plus interest
expense incurred on borrowings under our line of credit facility prior to the
issuance of the convertible debentures.

Net income (loss). Net loss for the nine months ended September 30, 2001
was $23.0 million as compared to net income of $2.2 million for the nine months
ended September 30, 2002, an increase in income of $25.2 million. The increase
was due primarily to decreases in cost of sales, operating expenses,
restructuring and impairment charges and amortization of intangible assets
offset by decreased revenue.

Liquidity and Capital Resources

At December 31, 2001, our unrestricted cash balance was $5.9 million
compared to $12.2 million as of September 30, 2002, an increase of $6.3 million.
This increase is primarily attributable to $9.6 million in cash received from
the issuance of convertible debentures, net of issuance costs, in March 2002,
offset by cash used in operations as well as the payment of the outstanding
balances under our credit facility and capital leases. Net cash used in
operating activities during the nine months ended September 30, 2002 was $0.5
million. We also used cash of $0.9 million to purchase equipment and other fixed
assets, made principal payments on capital lease obligations of $0.3 million and
made principal payments on our credit facility obligations of $2.0 million. Cash
provided by the sale of common stock pursuant to the exercise of employee stock
options and our employee stock purchase plan was $0.3 million.

We require substantial working capital to fund our business, particularly
to finance inventories, accounts receivable, research and development activities
and capital expenditures. To date, we have financed our operations and capital
expenditures primarily with the proceeds from our initial public offering
completed in February 1998, our operating income and the proceeds from the
issuance of convertible debentures in March 2002. In 2001, we became dependent
on cash that was provided by our bank under a credit facility. In addition, from
time to time, we have obtained advance payments in connection with certain
customer purchase orders. In the fourth quarter of 2001, we received an advance
payment of approximately $3.6 million that was classified as a customer deposit
in the accompanying consolidated balance sheet as of December 31, 2001; the
related customer orders were fulfilled in February 2002. We do not anticipate
receiving customer advance payments in the future. Our future capital
requirements will depend on many factors, including the rate of revenue growth,
if any, as well as our gross margin and our levels of operating expenses,
including product research and development, sales and marketing and general and
administrative expenses.

Our revenue for the nine months ended September 30, 2002 was $46.7
million, which was a decrease of $10.2 million compared to the nine months ended
September 30, 2001. In response to the trends of decreasing revenue and
increasing operating expenses that began in the second quarter of 2000 following
our acquisition of Avesta, we initiated a restructuring plan in the fourth
quarter of 2000 to realign our product portfolio, streamline our operations and
devote resources to the markets and products that we believe have the greatest
opportunity for growth. In the second quarter of 2001, we announced a plan to
discontinue development and sales efforts on the Visual Trinity product, the
primary product acquired from Avesta, and eliminate the related costs. In the
fourth quarter of 2001 and first and second quarters of 2002, we made additional
reductions in staff and other operating costs. As a result of these actions,
operating expenses, excluding charges related to acquisitions and restructuring
and impairment charges, have been reduced from a level of $49.9 million for the
nine months ended September 30, 2001 to $30.6 million for the nine months ended
September 30, 2002. As a result of our cost reductions to date, we returned to
profitability for the three and nine months ended September 30, 2002.

Our ability to generate operating income in the future is dependent upon
not only our continued success in reducing operating expenses, but also our
ability to sustain revenue. General market conditions, competitive pressures and
other factors beyond our control may adversely affect our ability to generate
sufficient revenue to enable us to remain profitable. Our ability to sustain
revenue may be negatively affected by our dependence on sales to our service
providers. Pressure on capital expenditures and the decline in the
telecommunications industry may delay the roll-out of new services offered by
our service providers based on our products. Furthermore, any potential
reduction in demand for value added services or products from the service
providers' customers directly impacts the volume of our products purchased and
may impact our ability to sustain revenue. However, we believe that our revenue
goals are achievable based on the role that our products have in directly
enhancing our service providers' product offerings and related profit margins.

The recent events at WorldCom did not have a significant impact on revenue
from WorldCom for the nine months ended September 30, 2002. However, WorldCom's
bankruptcy could have a material adverse impact on our future revenue. As of
September 30, 2002, WorldCom owed us $0.1 million that is included in accounts
receivable in the accompanying balance sheet. We wrote-off approximately $0.7
million in accounts receivable related to amounts WorldCom owed to us prior to
the bankruptcy filing against the allowance for bad debts during the nine months
ended September 30, 2002. Any future recoveries of these written off receivables
will be recorded when and if they are received.

The current level of our operating expenses, which include a substantial
fixed component in the form of compensation, other employee-related costs,
occupancy costs and other costs incurred under contractual arrangements, is
based, in part, on our expectation of future revenue. In the event that the
anticipated cost reductions are not realized or we do not meet our revenue
goals, we may be required to further reduce our cost structure. While we are
able to further reduce these expenses, should reductions become appropriate, it
would take at least thirty to ninety days for the full effects of any such
further expense reductions to be felt. If revenue

22


levels are below expectations, operating results are likely to be materially and
adversely affected because we may not be able to reduce operating expenses in
sufficient time to compensate for the reduction in revenue. There can be no
assurances that we will be able to sustain revenue or remain profitable. Failure
to sustain revenue and remain profitable coupled with our limited capital
resources and significant accumulated deficit could also result in our inability
to continue as a going concern.

The significant operating losses incurred by us since the third quarter of
2000 have resulted in a significant reduction in our cash. In order to
strengthen our financial position and provide cash for working capital purposes,
in March 2002, we issued senior secured convertible debentures in the aggregate
amount of $10.5 million in a private placement. The debentures are due March 25,
2006, are payable in common stock or cash, at our option, provided certain
conditions are satisfied and bear interest at an annual rate of 5% payable
quarterly in common stock or cash, at our option, provided certain conditions
are satisfied. The debentures are secured by a first priority lien on
substantially all of our assets. The debentures may be converted initially into
2,986,093 shares of our common stock at the option of the holders at a price of
$3.5163 per share, subject to certain adjustments. The conversion price will
adjust if we issue certain additional shares of our common stock or instruments
convertible into common stock at a price that is less than the conversion price
of the debentures. We have the right to require the holders to convert their
debentures into common stock if the closing price of our common stock exceeds
175% of the conversion price for 20 consecutive days after September 26, 2003.

The debentures include certain financial covenants related to earnings
before interest, taxes, depreciation and amortization for 2002 and 2003. If the
financial covenants are not met, the holders may cause us to redeem the
debentures at a price equal to the principal amount of the debentures plus
accrued interest. The redemption may be made in common stock or cash at our
option provided certain conditions are satisfied. Cash redemption of the
debentures also may be required upon a specified change of control or upon the
occurrence of any one of the other triggering events, including but not limited
to, our default on other indebtedness and our failure to maintain our common
stock listing on an eligible market. In the event that the financial covenant
for 2002 is achieved, the first priority lien in favor of the debenture holders
shall be released.

We also issued warrants to purchase 828,861 shares of our common stock at
an initial exercise price of $4.2755 per share. The exercise price may be
adjusted if we issue certain additional shares of our common stock or
instruments convertible into common stock at a lower price than the initial
exercise price. The warrants expire on March 25, 2007. The holders of the
debentures also received the right to purchase shares of to-be-created Series A
preferred stock (the "Preferred Stock Rights") at certain dates in the future.
The first Preferred Stock Right for 575 shares for $5.8 million expired on May
6, 2002. The holders did not exercise the right to purchase these shares of
Series A preferred stock. A second Preferred Stock Right for 307 shares for $3.1
million may be exercised at any time after the six-month anniversary but before
the fifteen-month anniversary of the issuance of the debentures. A third
Preferred Stock Purchase Right for 170 shares for $1.7 million expired on May 6,
2002. The holders did not exercise the right to purchase these shares of Series
A preferred stock. The debenture holders were also granted certain equity
participation and registration rights.

Under the terms of the debentures, a number of events could trigger the
debenture holders' right to force early repayment of 115% of the outstanding
principal plus accrued and unpaid interest owed under the debentures. Events
constituting a triggering event include:

o our default on other indebtedness or obligations under any other
debenture, any mortgage, credit agreement or other facility,
indenture agreement, factoring agreement or other instrument under
which there may be issued, or by which there may be secured or
evidenced, any indebtedness for borrowed money or money due under
any long term leasing or factoring arrangement in an amount
exceeding $500,000;

o failure to have our common stock listed on an eligible market;

o our bankruptcy;

o engaging in certain change in control, sale of assets or redemption
transactions;

o failure to timely file our 2002 or 2003 annual reports; and

o certain other failures to perform our obligations under the
debenture agreement and/or the related agreements.

In addition, if our earnings before interest, taxes, depreciation and
amortization, less capital expenditures, for the fiscal year ended December 31,
2002 is less than $2.8 million, our debenture holders may require that we prepay
all or a portion of up to 50% of the outstanding principal amount of their
debentures. If our earnings before interest, taxes, depreciation and
amortization, less capital expenditures, for the fiscal year ended December 31,
2003 is less than $6.5 million, our debenture holders may require that we prepay
all or a portion of up to 100% of the outstanding principal amount of their
debentures.

23


If we do not have sufficient cash to repay these amounts early, we may be
required to seek additional capital through a sale of assets, sale of additional
securities or through additional borrowings, none of which may be available on
terms reasonably acceptable to us.

In connection with the issuance of the debentures, the outstanding amounts
borrowed from the bank under our accounts receivable-based and our equipment
financing arrangements were repaid, and the related loan agreements were
terminated. The standby letter of credit, as amended, issued by the bank in
December 2000 in the amount of $2.5 million with an expiration date of September
30, 2003 remains outstanding and secured with our pledge of a certificate of
deposit in the amount of $2.5 million that matures on May 31, 2003.

The following table represents our future minimum payments (including
interest) related to our outstanding Debentures and obligations we have under
operating leases (unaudited, in thousands):

Subsequent to the receipt of the $10.5 million investment, our cash
position has improved. Our balance of cash and cash equivalents was $12.2
million as of September 30, 2002, up $6.3 million from December 31, 2001.
Accounts payable and accrued expenses totaled $8.5 million at September 30,
2002, down $3.2 million from December 31, 2001, and current assets exceeded
current liabilities by approximately $8.1 million.

The future success of our company will be dependent upon, among other
factors, our ability to generate adequate cash for operating and capital needs.
We are relying on our existing balance of cash and cash equivalents and the net
proceeds from the issuance of the convertible debentures discussed above
together with future sales and the collection of the related accounts
receivable, at least at the levels set forth in our business plan, to meet our
future cash requirements for at least the next twelve months. If cash provided
by these sources is not sufficient, we will be required to further reduce our
expenditures for operations or to seek additional capital through other means
that may include the sale of assets, the sale of equity securities or additional
borrowings. There can be no assurance that additional capital will be available,
or available on terms that are reasonable or acceptable to us. If we are unable
to generate additional cash, our business and financial condition may be
materially and adversely affected such that we may need to consider other
alternatives for our future.

Critical Accounting Policies and Estimates

Our significant accounting policies are described in Note 1 of Notes to
Consolidated Financial Statements and more fully in our Annual Report on Form
10-K/A. We consider the accounting policies related to revenue recognition and
inventory valuation to be critical to the understanding of our results of
operations. Our critical accounting policies also include the areas where we
have made the most difficult, subjective or complex judgments in making
estimates, and where these estimates can significantly impact our financial
results under different assumptions and conditions. We prepare our financial
statements in conformity with generally accepted accounting principles in the
United States. As such, we are required to make certain estimates, judgments and
assumptions that we believe are reasonable based upon the information available.
These estimates and assumptions affect the reported amounts of assets and
liabilities at the date of the financial statements and the reported amounts of
revenue and expenses during the periods presented. Actual results could differ
from those estimates.

Revenue Recognition

Our revenue recognition policies follow the American Institute of
Certified Public Accountants Statement of Position No. 97-2, "Software Revenue
Recognition" and SEC Staff Accounting Bulletin No. 101, "Revenue Recognition in
Financial Statements," which summarizes existing accounting literature and
requires that four criteria be met prior to the recognition of revenue. Our
accounting policies regarding revenue recognition are written to comply with the
following criteria (see Note 1 of Notes to Consolidated Financial

24


Statements): 1) persuasive evidence of an arrangement exists; 2) delivery has
occurred; 3) the fee is fixed and determinable; and 4) collectibility is
probable. The third and fourth criteria may require us to make significant
judgments or estimates.

To determine if a fee is fixed and determinable, we evaluate rights of
return, customer acceptance rights, if applicable, and multiple-element
arrangements of products and services to determine the impact on revenue
recognition. Our agreements generally have not included rights of return except
in certain reseller relationships that include stock rotation rights. If an
agreement provides for a right of return, we recognize revenue when the right
has expired or the product has been resold by the master distributor. If an
agreement provides for evaluation or customer acceptance, we recognize revenue
upon the completion of the evaluation process, acceptance of the product by the
customer and completion of all other criteria. Revenue from multiple-element
software arrangements is recognized using the residual method whereby the fair
value of any undelivered elements, such as customer support and services, is
deferred and any residual value is allocated to the software and recognized as
revenue upon delivery. The fair values of professional services, technical
support and training have been determined based on our specific objective
evidence of fair value. Our vendor specific objective evidence of fair value is
based on the price that we charge customers when the element is sold separately.

Our maintenance contracts require us to provide technical support and
unspecified software updates to customers on a when and if available basis. We
recognize customer support revenue, including support revenue that is bundled
with product sales, ratably over the term of the contract period, which
generally ranges from one to five years. We recognize revenue from services when
the services are performed. Subscription fees for our benchmark reports are
recognized upon delivery of the reports.

We sell our products directly to service providers, end-user customers and
through indirect channels. Certain reseller customers have stock rotation
rights, under which the customer can exchange previously purchased products for
other products of equal or greater cost, subject to certain limitations, based
on their end-user customers' requirements. We recognize revenue under these
arrangements once the stock rotation right expires or the product has been
resold by our master distributor.

We also examine the specific facts and circumstances of all sales
arrangements with payment terms extending beyond our normal payment terms to
make a determination of whether the sales price is fixed and determinable and
whether collectibility is probable. Payment terms are not tied to milestone
deliverables or customer acceptance. Our evaluation of the impact on revenue
recognition, if any, includes our history with our customers and the specific
facts of each arrangement. It is generally not our practice to offer payment
terms that differ from our normal payment terms, and we have not written off any
accounts receivable related to extended payment term arrangements.

Inventory

Because of the order lead times required to obtain manufactured product,
we must maintain sufficient quantities of inventory of all of our products to
meet expected demand. If actual demand is much lower than forecasted, we may not
be able to dispose of our inventory at or above its cost. We write down our
inventory for estimated excess and obsolete amounts to the lower of cost or
market value. If future demand is lower than currently estimated, additional
write-downs of our inventory may be required.

Allowance for Bad Debt

We grant credit terms without collateral to our customers and, prior to
September 30, 2002, have not experienced any significant credit related losses.
During the nine months ended September 30, 2002, the Company wrote-off
approximately $0.7 million in receivable balances due from WorldCom following
WorldCom's bankruptcy filing against the allowance for bad debts. Any future
recoveries of these written-off receivables will be recorded when and if they
are received. Accounts receivable include allowances to record receivables at
their estimated net realizable value, which is determined based on estimates for
bad debt. If future events occur that impact our customers, additional
write-downs of our accounts receivable may be required.

Factors That May Affect Future Results

Our operations and financial condition are subject to certain other risks
and uncertainties, including among others, our accumulated deficit and
uncertainty of future profitability and possible fluctuations in financial
results, dependence on network service providers, substantial fixed operating
costs, possible dilution to our common stockholders, dependence on sales to key
customers, including WorldCom, dependence on a sole-source subcontract
manufacturer, potential delisting and reduced liquidity of our shares resulting
from failure to meet Nasdaq listing requirements, the potential triggering of
early repayment of our debentures, the downturn in the telecommunications
industry, long sales cycles, improvements to the infrastructure of the Internet,
rapid technological change, growing competition from several market segments,
errors in our products, dependence upon sole and limited source suppliers,

25


potential fluctuations in component pricing, potential claims of patent
infringement by third parties, potential failure to protect our intellectual
property rights, dependence upon key employees, ability to retain employees and
the defense of a purported class action lawsuit. In addition, the September 11,
2001 terrorist attacks and the military actions being taken by the United States
and its allies have created substantial economic and political uncertainties
that could have an adverse effect on Visual Networks' business. The market for
our products is growing and our business environment is characterized by rapid
technological changes, changes in customer requirements and new emerging market
segments. Consequently, to compete effectively, we must make frequent new
product introductions and enhancements and deploy sales and marketing resources
to take advantage of new business opportunities. Failure to meet any of these
and other challenges could adversely affect our future operating results.

In light of the uncertainty regarding the use of past audits by Arthur
Andersen LLP, our former auditors, we may be required to take action, including
asking our current auditors, PricewaterhouseCoopers LLP, to undertake an audit,
with respect to our financial statements for the periods ended December 31,
2001. We may undertake this action if we conclude that to do so would increase
our flexibility with respect to future transactions and corporate structuring or
ensure that we can meet our compliance requirements. No such transactions are
currently planned.

This Quarterly Report on Form 10-Q contains forward-looking information
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934, and is subject to the safe harbor
created by those sections. Our future results may be impacted by the various
important factors summarized in this Quarterly Report and more fully discussed
in our Annual Report on Form 10-K/A (Amendment No. 2) for the year ended
December 31, 2001.

Item 3. Qualitative and Quantitative Disclosure About Market Risk

During the three months ended March 31, 2002, we issued long-term debt in
the form of the convertible debentures discussed in Note 3 of Notes to
Consolidated Financial Statements. The convertible debentures bear interest at a
fixed annual rate of 5%. There have been no other material changes in the market
risks faced by us or in how those risks are managed since December 31, 2001.
Refer to our Annual Report on Form 10-K/A (Amendment No. 2) for year ended
December 31, 2001 for a discussion about such market risk.

While substantially all of our product sales to date have been made to
customers in the United States, we plan to sell our products to foreign
customers at prices denominated in U.S. dollars. However, if we commence selling
material volumes of product to such customers at prices not denominated in U.S.
dollars, we intend to adopt a strategy to hedge against fluctuations in foreign
currency.

Item 4. Controls and Procedures

Our management, under the supervision and with the participation of Peter
J. Minihane, our Interim President and Chief Executive Officer and principal
financial officer, performed an evaluation of the effectiveness of the design
and operation of our disclosure controls and procedures within 90 days before
the filing of this quarterly report. Based on that evaluation, Mr. Minihane
concluded that our disclosure controls and procedures are effective. There have
been no significant changes in our internal controls or in other factors that
could significantly affect internal controls subsequent to this evaluation.

PART II -- OTHER INFORMATION

Item 1. Legal Proceedings

In July, August and September 2000, several purported class action
complaints were filed against us and certain former executives (collectively,
the "defendants"). These complaints have since been combined into a single
consolidated amended complaint (the "complaint"). The complaint alleges that
between February 7, 2000 and August 23, 2000, the defendants made false and
misleading statements, which had the effect of inflating the market price of our
stock, in violation of Sections 10(b) and 20(a) of the Securities Exchange Act
of 1934. On August 20, 2002, United States District Judge Deborah K. Chasanow
entered an order in the United States District Court for the District of
Maryland dismissing the complaint. On September 17, 2002, the plaintiffs
appealed the District Court's decision to the United States Court of Appeals for
the Fourth Circuit. The complaint does not specify the amount of damages sought.
We believe that the plaintiffs' claims are without merit and intend to defend
against these allegations vigorously. We expect that a substantial portion of
the legal costs that we have incurred and may continue to incur related to this
matter will be paid by our directors' and officers' insurance policy. We cannot
presently determine the ultimate outcome of this action. A negative outcome
could have a material adverse effect on our financial position or results of
operations. Failure to prevail in the litigation could result in, among other
things, the payment of substantial monetary damages, in excess of any amounts
paid by our directors' and officers' insurance. We have not recorded any
liability related to this matter in the accompanying balance sheets as of
December 31, 2001 and September 30, 2002.

We are periodically a party to disputes arising from normal business
activities including various employee-related matters. In the opinion of
management, resolution of these matters will not have a material adverse effect
upon our financial position or future operating results.

Item 2. Changes in Securities and Use of Proceeds

None.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Submission of Matters to Vote of Security Holders

None.

Item 5. Other Information

None.

(b) Reports on Form 8-K

(1) The Company filed a Current Report on Form 8-K on August 19, 2001,
reporting that the Quarterly Report on Form 10-Q for the quarter
