NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Operations and
Significant Accounting Policies:



Visual Networks, Inc.
(the Company) designs, manufactures, sells and supports performance management platforms for communications networks.



Risk Factors



The Company is subject to certain risks and uncertainties which could affect its ability to continue as a going concern. These risks and uncertainties
include, but are not limited to: the timing and nature of repayment of the outstanding debentures (see Note 3), expenses and an uncertain outcome associated with the Paradyne litigation (see Note 4), customer migration to UpTime Select,
availability of hardware components, reliance on two subcontract manufacturers, limited access to the new line of credit (see Note 2), substantial dilution if the Company is required to raise capital through the sale of equity, the Companys
history of losses and the size of its accumulated deficit, uncertainty about future profitability, dependence on a limited number of major service provider customers for the majority of its revenue, long sales cycles, rapidly changing technology,
competition from several market segments, potential errors in the Companys products or services, and anti-takeover protections that may delay or prevent a change in control that could benefit stockholders.



The future success of the Company will depend upon its ability to generate
adequate cash for operating and capital needs. The Company is relying on its existing balance of cash and cash equivalents ($12.5 million at September 30, 2004), together with future sales and the collection of related accounts receivable to meet
its future operating cash requirements. If cash provided by these sources is inadequate and the new line of credit is not available or sufficient to fund future operations, the Company will be required to further reduce its expenditures for
operations or to seek additional capital through other means that may include additional borrowings, the sale of equity securities or the sale of assets. Under those circumstances, there can be no assurances that additional capital would be
available under reasonable or acceptable terms, particularly in light of the Companys history of losses and accumulated deficit position.



Financial Statement Presentation



The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America 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 the financial statements and the reported amounts of revenue and expenses during the
reporting periods. Actual results could differ from those estimates.



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 for the year ended December 31, 2003. 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 three and nine months ended September 30, 2004 are not necessarily indicative of the results that will be achieved for the year ended
December 31, 2004.

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



At June 30, 2004, the Company
held a certificate of deposit (CD) in the amount of $0.5 million which matured on July 31, 2004. This CD collateralized a $0.5 million letter of credit expiring on September 30, 2004 that was issued in favor of a subcontract
manufacturer. The balance of this collateralizing CD was $1.5 million at December 31, 2003. During the three months ended September 30, 2004, the subcontract manufacturer eliminated its letter of credit requirement and the $0.5 million CD was
transferred to cash.



At June 30, 2004, the Company held
another CD in the amount of $28,000, which matured on August 25, 2004 and collateralized a $28,000 letter of credit expiring on July 30, 2004 that was issued in favor of a customer. The balance of this collateralizing CD was $28,000 at December 31,
2003. During the three months ended September 30, 2004, the customer eliminated its letter of credit requirement and the $28,000 CD was transferred to cash.



The CDs were reflected as restricted short-term investments in the accompanying consolidated balance sheet at December 31, 2003.

Revenue Recognition



The Companys products and services include hardware, software,
professional services and technical support. The Company sells its products directly to service providers, through resellers (indirect channels) and, occasionally, to end-user customers. Professional services and technical support revenues are
included in support and services revenue in the accompanying consolidated statements of operations. The Company recognizes revenue from software licensing in accordance with the American Institute of Certified Public Accountants Statement of
Position (SOP) No. 97-2, Software Revenue Recognition. The Company recognizes revenue from the sale of hardware in accordance with SEC Staff Accounting Bulletin (SAB) No. 104, Revenue Recognition,
which summarizes existing accounting literature and requires that four criteria be 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; 3) the fee is fixed or determinable; and 4) collectibility is probable.



To determine if a fee is fixed or determinable, the Company evaluates rights of return, customer acceptance rights (if applicable), extended payment terms
(if any), and multiple-element arrangements of products and services to determine the impact on revenue recognition.



The Companys 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, the Company typically recognizes revenue when the right has expired or a specific end-user customer has been identified. If the Company has sufficient historical information to allow it to make an
estimate of returns in accordance with the Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards (SFAS) No. 48, Revenue Recognition When Right of Return Exists, the Company defers
revenue based on an estimate for such returns.



If an agreement
provides for evaluation or customer acceptance, the Company recognizes revenue upon the completion of the evaluation process, acceptance of the product by the customer and completion of all other criteria.



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



8

##### Table of Contents

whether the sales price is fixed or determinable and whether collectibility is probable. Payment terms generally 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 the particular customer and the specific facts of each arrangement. It is generally not the
Companys practice to offer payment terms that differ from its normal payment terms, and the Company has not written off any accounts receivable related to extended payment term arrangements.



Many of the Companys sales are multiple element arrangements and
include hardware, software, and technical support. The Companys software sales sometimes include professional services for implementation but these services are not a significant source of revenue. Training is also offered but is not a
significant source of revenue. Revenue from multiple element 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 any undelivered elements, typically professional services, technical support and training, have been determined based on the Companys specific objective
evidence of fair value, which is based on the price that the Company charges customers when the element is sold separately. Should the Company introduce new multiple element arrangements into its sales channels, a determination of the objective
evidence of the fair value of the undelivered elements will be necessary and an inability to provide objective evidence could impact the Companys ability to recognize revenue.



The Company generally recognizes revenue from services when the services are performed. The Companys technical support
contracts require it to provide technical support and unspecified software updates to customers on a when and if available basis. The Company recognizes 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 three years.



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.



Accrued Warranty Costs



The Company warrants Visual UpTime hardware for a period of up to five years. The Company warrants Visual UpTime Select hardware for one year. The
Company estimates its warranty obligation at the end of each period and charges changes in the liability to cost of revenue in the respective period. Such estimates are based on actual warranty cost experience.

warranty costs during the three months ended September 30, 2003 and 2004 (unaudited, in thousands):

Segment Reporting and Significant
Customers



Management has concluded that the
Companys operations occur in one segment based upon the information used by management in evaluating the performance of the business. The revenue and assets of the Companys foreign subsidiaries have not been significant.



For the three months ended September 30, 2003, four customers individually
represented 28%, 18%, 14% and 12% of revenue. For the three months ended September 30, 2004, three customers individually represented 29%, 28% and 15% of revenue. For the nine months ended September 30, 2003, three customers individually represented
32%, 20% and 12% of revenue. For the nine months ended September 30, 2004, four customers individually represented 23%, 21%, 18% and 15% of revenue.



The Companys major service provider customers include, among others: AT&T, MCI, SBC, Sprint and Verizon. Revenue from service providers as a
percentage of total revenue was 78% and 88% for the three months ended September 30, 2003 and 2004, respectively. Revenue from service providers as a percentage of total revenue was 82% and 87% for the nine months ended September 30, 2003 and 2004,
respectively. The supply agreements with the Companys significant customers do not contain minimum purchase requirements.



As of September 30, 2004, three customers individually represented 31%, 28%, and 18% of accounts receivable.



Accounting for Stock Options



During the three months ended March 31, 2004, the Company granted
non-qualified stock options to purchase 465,213 shares of common stock to employees, under the 1997 Non-Qualified Stock Option Plan, at an issuance price that was less than the fair market value of the Companys common stock and recorded
deferred compensation of $330,000. The deferred compensation is being amortized over the vesting period of the stock options, which is 20% as of the grant date and the remaining portion over 24 equal monthly installments after the grant date. As a
result, the Company recorded deferred compensation expense of approximately $33,000 and $154,000 during the three and nine months ended September 30, 2004, respectively. The Company also recorded deferred compensation expense of $2,000 during the
nine months ended September 30, 2003.



If compensation expense
had been determined based on the fair value of the options at the grant dates consistent with the method of accounting under SFAS No. 123, Accounting for Certain Transactions Involving Stock Compensation, as amended by SFAS No. 148,
Accounting for Stock-Based Compensation-Transition and Disclosure, the Companys net earnings (loss) per share would have changed to the pro forma amounts indicated below (unaudited, in thousands, except per share amounts):

##### Table of Contents

The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing
model with the following assumptions used for grants during the nine months ended September 30, 2003 and 2004: no dividend yield, expected volatility from 180% to 395%, risk-free interest rates from 2.9% to 3.5% and an expected term of 5 years.
Assumptions used in determining the fair value of options are used solely for this purpose and there is no prediction or guarantee that the expense reflected under these assumptions will be realized.



Basic and Diluted Earnings (Loss) Per Share



Basic earnings or loss per share includes no dilution effect and is computed
by dividing net earnings or net loss available to common stockholders by the weighted-average number of common shares outstanding for the period.



Diluted earnings or 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 9,522,969 shares of common stock outstanding at September 30, 2003 were not included in the computation of diluted loss per share for the three and nine months ended September 30, 2003 as their effect would be anti-dilutive. The effect of
the Debentures issued in March 2002 (see Note 3) that were potentially convertible into 2,986,093 shares of common stock at September 30, 2003 has not been included in the computation of diluted loss per share for the three and nine months ended
September 30, 2003 as such effect would be anti-dilutive.



Options and warrants to purchase 10,544,748 shares were outstanding at September 30, 2004. The dilutive effect of certain of the options resulted in the addition of 1,841,736 shares in the computation of diluted earnings per share for the
three months ended September 30, 2004. Options and warrants outstanding at September 30, 2004 were not included in the computation of diluted loss per share for the nine months ended September 30, 2004 as their effect would be anti-dilutive. The
effect of the Debentures that are potentially convertible into 2,559,509 shares of common stock at September 30, 2004 has not been included in the computation of diluted earnings and loss per share for the three and nine months ended September 30,
2004, respectively, as such effect would be anti-dilutive.



The
computation of the earnings or loss per share is as follows (unaudited, in thousands, except per share data):

Adjustment



Prior to the Companys initial public offering in February 1998, a reserve was established to cover sales returns and allowances. The establishment
of this reserve was in accordance with Generally Accepted Accounting Principles in the United States of America and the balance of $1.7 million has been reflected as Deferred Revenue in the annual Consolidated Balance Sheets audited through December
31, 2003 and in the interim financial information through June 30, 2004.



The Companys current management has reviewed this $1.7 million reserve and has not found any evidence supporting its balance due to the fact that the Companys auditor at the time of the reserve
establishment has ceased to exist and personnel who were responsible for the account are no longer with the Company. The Companys position is that it is not appropriate for this unsubstantiated $1.7 million reserve balance to remain reflected
as a liability on the Companys Consolidated Balance Sheets.



Management has determined that it would not amend the Companys Annual Report on Form 10-K for the year ended December 31, 2003 to reflect a prior period reversal of the $1.7 million reserve balance. Management believes that it is not
practicable for prior year financial statements to be re-audited and the reserve balance reversal would not have an adverse effect on those prior year financial statements.



An adjustment reflecting a $1.7 million decrease in Deferred Revenue and a corresponding $1.7 million decrease in
Accumulated Deficit is reflected in the Consolidated Balance Sheet at September 30, 2004. When the Company files its Form 10-K for the year ended December 31, 2004 the Company will adjust the Deferred Revenue and Accumulated Deficit for all
periods presented for this $1.7 million adjustment.



2. Line of Credit:



In July 2004, the Company and Silicon Valley Bank
(SVB) entered into a $6.0 million line of credit agreement. Borrowings under the line of credit are available once the Debentures (see Note 3) have been fully repaid. The Company entered into this line of credit agreement primarily to
provide additional capital in the event that the Debenture holders exercise their right to require the Company to repay the Debentures in full prior to their due date, and the Company makes all or a substantial portion of the repayment in cash. No
amounts are outstanding under this line of credit at September 30, 2004.



The line of credit agreement with SVB expires on July 22, 2005, at which time any outstanding advances under the agreement are immediately payable. Under the agreement, the Company can borrow amounts not exceeding the
lesser of (i) $6.0 million or (ii) a borrowing base which is 80% of eligible accounts receivable as defined in the agreement. Interest is payable monthly at the greater of (i) SVBs prime rate plus 1.25% per annum or (ii) 5.25% per annum.
Collateral under the agreement consists of the Companys right, title and interest in and to substantially all of its assets other than its intellectual property. Once the Debentures are repaid, the agreement subjects the Company to certain
financial and other covenants, which are presently met.



3. Convertible
Debentures:



In March 2002, the Company issued senior
secured convertible debentures (the Debentures) in the aggregate amount of $10.5 million in a private placement. The Debentures are due March 25, 2006, are payable in cash or common stock at the Companys option provided certain
conditions are satisfied, which are currently satisfied. The Debentures bear interest at an annual rate of 5% payable quarterly in cash or common stock, at the Companys option, provided certain conditions are satisfied, which are currently
satisfied. To date, all quarterly interest payments under the Debentures have been made in cash. The Debentures were convertible into 2,986,093 shares of common stock at the option of the Debenture holders at a price of $3.5163 per share, subject to
certain adjustments. The conversion price of the Debentures will adjust if the Company



12



---

##### Table of Contents

issues additional equity or instruments convertible into equity 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 Debenture holdings into common stock if the value weighted average price of the Companys common stock exceeds 175% of the conversion price
for 20 consecutive trading days. Debentures totaling $1.5 million were paid in cash in June 2004. The remaining Debentures totaling $9.0 million are convertible into 2,559,509 shares of common stock at September 30, 2004.



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 exercise price of $4.2755 per share. If the Company issues additional equity or instruments convertible into equity at a lower price than the then-effective exercise price, the
exercise price would be adjusted downward on a weighted average basis. The warrants expire on March 25, 2007.



Because the Company did not meet the earnings target for 2003 set forth in the Debentures, the Debenture holders may require that the Company repay, in
whole or in part, at any time and from time to time, the outstanding principal amount of their Debenture holdings, plus accrued interest. Under the terms of the Debentures: (i) a Debenture holder electing payment for some portion of the Debentures
must notify the Company of this election; (ii) the Company, in turn, must notify the Debenture holder of the manner in which it intends to repay that Debenture holder (either all cash or all common stock); and (iii) the notifying Debenture holder
then notifies the Company of the amount to be paid in that form at that time. The redemption of each Debenture may be made in cash or common stock, at the Companys option, provided certain conditions are satisfied, which the Company currently
satisfies.



In addition, 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:



| |  | 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;
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | failure by the Company to have its common stock listed on an eligible market;
| | - | -----------------------------------------------------------------------------



| |  | failure to have an effective registration statement covering the shares of common stock issuable upon conversion of the Debentures or exercise of the warrants;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | bankruptcy of the Company;
| | - | --------------------------



| |  | engagement by the Company in certain change in control, sale of assets or redemption transactions; and
| | - | ------------------------------------------------------------------------------------------------------



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



The aggregate amount of the Debentures is reflected in the accompanying
balance sheets as a current liability of $10.5 million and $9.0 million, net of unamortized debt discount of approximately $1.8 million and $1.0 million, as of December 31, 2003 and September 30, 2004, respectively. The net amount 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 was allocated to the value of the warrants. Approximately $0.3 million in proceeds from the
Debentures was allocated to additional paid-in capital to recognize the value of the rights of the holders to purchase shares of preferred stock, which expired in 2002, as determined by an appraisal. On the date of issuance of the Debentures, the
conversion price of the Debentures was less than the

##### Table of Contents

quoted market price of the Companys common stock. Accordingly, approximately $0.7 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 feature is being amortized as a charge to interest expense over the four-year period until the Debentures become due in March 2006. Debt issuance costs of approximately $0.9 million were deferred and are being amortized over the term of
the Debentures. Because of the early repayment of $1.5 million of the outstanding Debentures in June 2004, a proportionate amount of the unamortized discount and debt issuance costs associated with this $1.5 million repayment was amortized. The
related charge of approximately $0.3 million has been included in other expense in the Statements of Operations for the nine months ended September 30, 2004.



4. Commitments and Contingencies:



In January 2004, the Company received notice that a lawsuit had been filed by Paradyne Networks, Inc. (Paradyne) of Largo, Florida, in the
United States District Court for the Middle District of Florida, Tampa Division (the  Florida Court), seeking damages, and injunctive and declaratory relief, for the Companys alleged infringement of patents owned by Paradyne
Corporation, a subsidiary of Paradyne.



On May 14, 2004, the
Florida Court granted the Companys motion to dismiss the case for lack of subject matter jurisdiction and denied Paradynes motion for leave to amend its complaint and its motion for preliminary injunction. Paradyne did not appeal the
decision.



In a related matter, one of the Companys
subsidiaries, Visual Networks Operations, Inc., filed a lawsuit in United States District Court for the District of Maryland, Southern Division (the Maryland Court), against Paradyne Corporation. This lawsuit requests declaratory
judgment that Visual UpTime and Visual IP InSight do not infringe certain patents owned by Paradyne Corporation and that those patents are invalid and unenforceable and alleges that Paradynes assertion of its patents against the Company is
baseless and has been for the sole purpose of obtaining an unfair competitive advantage, and that Paradyne has infringed certain patents owned by the Company. Paradyne filed counterclaims alleging the Visual Networks, Inc. infringement of its
patents, mirroring the Florida claims. On October 15, 2004, Paradyne Corporation filed amended counterclaims, adding allegations of willful patent infringement and unenforceability of two of the Companys patents in the lawsuit. The Maryland
lawsuit presently is in the fact discovery phase of the litigation. The Maryland Court has scheduled a hearing concerning patent claim construction for February 7, 2005. A trial date has not yet been scheduled.



Despite the Companys belief that its products do not infringe upon
Paradynes patents and that Paradynes claims are frivolous and without merit, the conduct of the litigation is expensive and may divert the Companys resources from other activities, which could have a material adverse effect on the
Companys business and results of operations. At this point in the litigation, the likelihood of any outcome cannot be determined and the adverse effect of any finding cannot be estimated.



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 various employee-related matters will not have a material adverse effect upon the Companys financial position or future operating results.



Litigation costs are expensed as incurred.

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



This Managements Discussion and Analysis of Financial Condition and Results of Operations may contain forward-looking statements that involve risks
and uncertainties. Under the section Risk Factors, we have described what we believe to be some of the major risks related to these forward-looking statements, as well as the general outlook for our business. Investors should review
these risk factors and the rest of this Quarterly Report in combination with the more detailed description of our business in our 2003 Annual Report on Form 10-K for a more complete understanding of the risks associated with an investment in our
common stock.



Overview



We design, manufacture, sell, and support performance management platforms
for communications networks. We have two product lines, UpTime and IP InSight.



These product lines allow businesses and organizations (which we call enterprises), and their providers of network services (which we call service providers and systems integrators) to measure the performance of their
networks, to determine whether a network is performing consistent with the requirements of the software applications running on that network, and to determine whether the level of service being provided is meeting those standards agreed upon by the
service provider and its enterprise customer. These platforms also help enterprises understand how their software applications and users are using the network, the performance those applications and users are experiencing, and required network
capacity. Our platforms constantly monitor the data traffic traveling between service providers and enterprises networks. Network operators using our platforms can quickly identify and isolate network problems without dispatching
personnel to remote sites. By learning how much traffic is traveling on the service provider network and understanding the characteristics of that traffic, network operators can efficiently address bandwidth capacity and response time issues.
Although our products do not currently perform any active control of networks or applications, they are categorized as performance management tools and we refer to our products as those that manage networks.



UpTime manages the performance of application delivery on private data
networks and consists of Visual UpTime® and Visual UpTime® Select. UpTime is our original flagship product suite. The vast majority of our revenues are derived from UpTime and UpTime Select.



UpTime Select was announced in October 2003 as the successor to UpTime. UpTime Select offers a flexible,
software-based solution that enterprise customers, service providers and systems integrators can cost-effectively implement and incrementally enhance in step with the unique and changing needs of their dynamic IT environments. We recorded initial
UpTime Select revenue in the three months ended June 30, 2004.



Visual IP InSight® is a software-based service performance management platform for public Internet Protocol (IP) networks. It enables service providers and enterprises to manage IP connectivity and accessibility to IP
network services from the end-users perspective. It helps manage IP connectivity independent of IP access technologies. A small portion of our revenues are derived from IP Insight.



We market our products to enterprises, service providers, and systems integrators. Network performance is critical to
enterprises because networks enable applications that are vital to an enterprises operations. Enterprises require tools to ensure the availability of their networks and the applications those networks support, to predict and validate network
performance, and to optimize the price/performance ratio of their networks.



Service providers and systems integrators use our products to create services that are differentiated from their competitors and to reduce their operating and other costs associated with initiating and providing
services for their customers. Our major service provider customers include, among others: AT&T, MCI, SBC, Sprint and Verizon.

We incurred net losses in 2003 and in the first six months of 2004. Our 2003 revenue was adversely
affected by a continued slowdown in the global economy and depressed end-user information technology spending. These factors contributed to significant competitive pressure on the average selling price of our products, tighter service provider
inventory control and the loss of business to competitors.



However, we have recorded sequential quarterly revenue improvement since the three months ended September 30, 2003. We also returned to profitability in the three months ended September 30, 2004. Despite these improvements, there can be no
assurance that there will be continued revenue growth and/or profitability.



Prior to our initial public offering in February 1998, a reserve was established to cover sales returns and allowances. The establishment of this reserve was in accordance with Generally Accepted Accounting Principles
in the United States of America and the balance of $1.7 million has been reflected as Deferred Revenue in the annual Consolidated Balance Sheets audited through December 31, 2003 and in the interim financial information through June 30, 2004.



Our current management has reviewed this $1.7 million reserve
and has not found any evidence supporting its balance due to the fact that our auditor at the time of the reserve establishment has ceased to exist and personnel who were responsible for the account are no longer with the Company. Our position is
that it is not appropriate for this unsubstantiated reserve balance to remain reflected as a liability on our Consolidated Balance Sheets.



Management has determined that it would not amend our Annual Report on Form 10-K for the year ended December 31, 2003 to reflect a prior period reversal
of the $1.7 million reserve balance. Management believes that it is not practicable for prior year financial statements to be re-audited and the reserve balance reversal would not have an adverse effect on those prior period financial statements.



An adjustment reflecting a $1.7 million decrease in Deferred
Revenue and a corresponding $1.7 million decrease in Accumulated Deficit is reflected in the Consolidated Balance Sheet at September 30, 2004. When the Company files its Form 10-K for the year ended December 31, 2004 the Company will adjust the
Deferred Revenue and Accumulated Deficit for all periods presented for this $1.7 million adjustment.



Results of Operations



The primary statements of operations components are:



Revenue. Our revenue consists of three types: hardware, software, and support and services. The fees we receive associated with the licensing of our software products are classified as software revenue. The sale of the
hardware component of the Visual UpTime and Visual UpTime Select platforms, the analysis service element (ASE), is classified as hardware. UpTime sales are primarily hardware. In contrast, UpTime Select sales have unbundled
hardware and software components and such sales are reflected under hardware and/or software as appropriate. Sales of IP InSight are primarily classified as software. Sales of discontinued products are software revenue. Sales of technical support,
professional services and training for all products are classified as support and services revenue.



Cost of revenue and gross profit.Product cost of revenue consists of contract manufacturing costs, component parts, warehouse costs,
warranty, 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 outsourced benchmark services, professional services and technical support costs.

Revenue



| |  | Hardware revenueincreased from period to period due to increased UpTime and Uptime Select hardware sales to SBC, MCI and Sprint primarily due to increased market
demand caused by the introduction of Visual UpTime Select. These increases were partially offset by decreased hardware sales to AT&T in 2004 due to tighter inventory controls. Revenue related to Visual UpTime hardware was $20.2 million
and $23.5 million during the nine months ended September 30, 2003 and 2004, respectively. No revenue related to Visual UpTime Select hardware was recorded during 2003. Revenue related to Visual UpTime Select hardware was $4.1 million
during the nine months ended September 30, 2004.

| |  | Software revenue increased from period to period due to UpTime Selectsoftware sales which began in 2004 and were $3.6 million during the nine months ended September
30, 2004. This increase was partially offset by a $0.5 million decrease in Visual IP Insight sales, which often fluctuate due to the uncertain timing of large orders. Revenue related to Visual IP Insight software was $0.6 million and $0.1 million
during the nine months ended September 30, 2003 and 2004, respectively.

Liquidity and Capital Resources



We require substantial working capital to fund our business, particularly to finance inventories, accounts receivable, research and development
activities, operating expenses 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), cash provided by operating
activities, bank borrowings, and the proceeds from the issuance of the Debentures. Our future capital requirements will depend on many factors, including the timing and nature of repayment of the Debentures, the rate of future revenue growth, if
any, and the acceptance of our new Visual UpTime Select product suite by our customers. Other relevant factors include gross profit and operating expense levels, including product research and development, sales and marketing and general and
administrative expenses. If cash provided by currently available sources is not sufficient, we will be required to further reduce our expenditures for operations and/or to seek additional capital through other means that may include additional
borrowings and/or the sale of equity securities or the sale of assets. Our access to the Silicon Valley Bank (SVB) line of credit, unavailable until the Debentures are fully repaid, may be limited if we have an insufficient borrowing
base or if we cannot meet the financial and other covenants required under the line of credit agreement. Under those circumstances, there can be no assurance that additional capital will be available, or available on terms that are reasonable or
acceptable to us, and our business and financial condition may be materially and adversely affected.



At September 30, 2004, our principal source of liquidity was our existing balance of cash and cash equivalents of $12.5 million.



Our operating activities consumed $3.1 million in cash and cash equivalents
for the nine months ended September 30, 2003 and 2004. A major factor affecting operating activities in 2003 was the $3.8 million decrease in accounts payable and accrued expenses, reflecting decreased business activity. Costs and operating expenses
were lower in the three months ended September 30, 2003 relative to the three months ended December 31, 2002.



A major factor affecting operating activities in 2004 was the $4.4 million increase in accounts receivable. The increase in accounts receivable was due to
increased revenue, the timing of billings in the three months ended September 30, 2004, and accelerated collections at the end of 2003.



Our investing activities provided cash and cash equivalents of $0.2 million and $0.8 million for the nine months ended September 30, 2003 and 2004,
respectively. Proceeds from certificate of deposit liquidations were approximately $1.0 and $1.5 million in the nine months ended September 30, 2003 and 2004, respectively (see Note 1 of Notes to Consolidated Financial Statements).



Our financing activities provided cash and cash equivalents of $0.3 million
for the nine months ended September 30, 2003 and used cash and cash equivalents of approximately $0.8 million in the nine months ended September 30, 2004. Changes in cash related to 2004 activities primarily reflect the repayment of $1.5 million in
Debentures (see Note 3 of Notes to Consolidated Financial Statements).

We have a subtenant
occupying a portion of our office space under a sublease that expires in December 2004. Future minimum lease payments due from the sublessee are approximately $0.1 million as of September 30, 2004. We are currently in negotiations with the sublessee
to extend the sublease to December 2005.



The terms of the
Debentures provide for a number of events that could trigger the Debenture holders right to force early repayment of 115% of the outstanding principal plus accrued and unpaid interest. The terms also included an earnings target related to our
financial performance, which we did not meet for 2003. As a result, the Debenture holders may require that we repay, in whole or in part, at any time and from time to time, the outstanding principal amount of their Debenture holdings, plus accrued
interest. Each early repayment, if any, may be made in cash or common stock, at our option, provided certain conditions are satisfied, which we currently satisfy. If we choose to issue common stock to repay the debt, our stockholders could be
subject to significant dilution.



On May 11, 2004, we received
a definitive, binding notice from two Debenture holders requesting the repayment in full of an aggregate of $1.5 million of our $10.5 million outstanding Debentures. Pursuant to this notice, on June 11, 2004, we paid $1.5 million in cash to these
two Debenture holders.



Should we receive any further repayment
requests, we intend to carefully evaluate and balance liquidity concerns against dilution considerations and make each determination of whether to repay in cash or common stock on a case-by-case basis. If we choose to repay a Debenture holder with
shares of our common stock and the per share issuance price of the stock is less than $3.5163, the conversion price of any outstanding Debentures would be adjusted downward to the issuance price of such stock. In addition, under the terms of the
warrants held by the Debenture holders, an issuance of shares below the exercise price of the warrants would cause the exercise price to be adjusted on a weighted-average basis. Based upon our current revenue and expense expectations, we believe
that we would have sufficient operating capital for at least the next twelve months in the event we repay the remaining $9.0 million in Debentures in cash.



The following table outlines the number of shares into which the Debentures would be convertible if we issue additional equity (including for repayment of
the Debentures) at prices specified, as well as the total percent of the outstanding shares of the Company that such shares would represent upon conversion, calculated using the number of shares outstanding as of November 10, 2004:

The warrants are subject to weighted average anti-dilution protection which would decrease the exercise
price and increase the number of shares issuable under the warrants. These changes would be determined once the total investment amount and price per share of any future equity issuance were known.



In order to provide us with additional capital resources in the event that
the Debentures are paid in full, we entered into a $6.0 million line of credit agreement with SVB. Borrowings under the line of credit would be available only after the Debentures are fully paid (see Note 2 of Notes to Consolidated Financial
Statements).



We are involved in a lawsuit in which we are
litigating our claims that (i) our products do not infringe patents owned by a competitor, those patents are invalid and unenforceable, and the competitors assertion of its patents against us is baseless and has been for the sole purpose of
obtaining an unfair competitive advantage and (ii) that competitor has infringed certain patents owned by us. The competitor has filed counterclaims alleging our infringement of its patents and unenforceability of two of our patents in the lawsuit.



Despite our belief that our claims are correct and that our
position will ultimately be vindicated, the conduct of this litigation is expensive and may divert our resources from other activities, which could have a material adverse effect on our business and results of operations. At this point in the
litigation, the likelihood of any outcome cannot be determined and the adverse effect of any finding cannot be estimated.



We have commitments related to inventory purchased by certain suppliers on our behalf. If such inventory is not used within a specified period of time or
we discontinue a product for which the suppliers have made purchases or we terminate a relationship with the supplier for which we have set minimum inventory requirements, we are required to purchase the excess inventory from the suppliers.
Additionally, if we cancel a purchase order placed with a supplier, we may be subject to certain costs and fees. As of September 30, 2004, anticipated demand exceeds the supply of inventory. As such, we do not have a liability recorded as of
September 30, 2004 for inventory purchase commitments.



We do
not engage in any off-balance sheet financing arrangements. In particular, we do not have any so-called limited purpose entities, which include special purpose entities and structured finance entities.



Critical Accounting Policies and Estimates



The preparation of consolidated financial statements requires us to make
estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. Those policies are described in our 2003 Annual Report on Form 10-K. On an ongoing
basis, we re-evaluate our estimates, including those related to bad debts, inventory, investment, income taxes, warranty obligations, and contingencies and litigation. We base our estimates on historical experience and on various other assumptions
that we believe to be reasonable under the circumstances. Among other things, these estimates form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may
differ from these estimates under different assumptions or conditions. We consider our critical accounting policies to be the following:



Revenue Recognition



We recognize revenue from the sale of hardware, the licensing of software and the provision of support and other services. Our revenue recognition
policies follow the American Institute of Certified Public Accountants Statement of Position (SOP) No. 97-2, Software Revenue Recognition and SEC Staff Accounting Bulletin (SAB) No. 104, Revenue
Recognition, which summarizes existing accounting literature and requires that four criteria be met prior to the recognition of revenue. Our accounting policies



25



---

##### Table of Contents

regarding revenue recognition are written to comply with the required criteria (see Note 1 of Notes to Consolidated
Financial Statements): 1) persuasive evidence of an arrangement exists; 2) delivery has occurred; 3) the fee is fixed or determinable; and 4) collectibility is probable. The third and fourth criteria may require us to make significant judgments or
estimates.



Reserve for Inventory Obsolescence



Because of the lead times required to obtain manufactured product, we must
maintain sufficient quantities of inventory for 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 the value of estimated
excess and obsolete inventory to the lower of cost or market value. The estimates are based on historical trends, forecasts and specific customer or transaction information. It is generally our policy to write down inventory based on the number of
items that we do not expect to sell within a one year period. If future demand is lower than currently estimated, additional write-downs of our inventory may be required. During the first nine months of 2004, we recorded a charge of $0.4 million
related to excess and obsolete inventory.



Deferred Tax Valuation
Allowance



We calculate a valuation allowance against
gross deferred tax assets in accordance with the provisions of Statement of Financial Accounting Standard No. 109, Accounting for Income Taxes (SFAS No. 109) which requires an assessment of both positive and negative evidence
when measuring the need for a valuation allowance. In managements opinion, our cumulative loss in the most recent three-year period represents sufficient negative evidence to require a full valuation allowance under the provisions of SFAS No.
109. We intend to maintain a full valuation allowance until sufficient positive evidence exists to support the reversal of any portion of the allowance.



Risk Factors



Investing in our securities involves a high degree of risk. In addition to the other information contained in this quarterly report, including the reports
we incorporate by reference, you should consider the following factors before investing in our securities.



Our Debenture holders now have the right to demand repayment of any or all of our Debentures at any time and from time to time.



Because we did not meet the financial targets for 2003 under our Debentures, the Debenture holders may require that we repay
any or all of the outstanding principal amount of their Debentures plus accrued interest at any time and from time to time. The choice of whether to repay all common stock or all cash is in our absolute discretion provided we meet certain criteria
specified in the Debentures, which we currently meet. If we choose to repay any such demand with common stock, such issuance would have a dilutive effect on our common stockholders. If the issuance price of such shares is below the then-current
conversion price of the Debentures, the conversion price of the Debentures is immediately reset to such lower price and the exercise price of the warrants and the number of shares issuable upon exercise would be adjusted upwards on a
weighted-average basis.



If we choose to repay any such demand
with cash, and we do not have sufficient cash to both repay amounts and to fund ongoing operations, 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 acceptable to us. Our business and financial condition could be materially and adversely affected.



The ongoing patent litigation between us and Paradyne, and any other potential intellectual property litigation, could have a significant detrimental effect on our
business.



Despite our belief that our products do not
infringe Paradynes patents and that



26



---

##### Table of Contents

Paradynes claims are frivolous and without merit, the conduct of this litigation is expensive and may divert our
resources from other productive activities, which could have a material adverse effect on our business and results of operations. At this point in the litigation, the likelihood of any outcome cannot be determined and the adverse effect of any
finding cannot be estimated.



Additionally, if others claim
that our products infringe on their intellectual property rights, whether the claims are valid or not, we may be forced to incur significant litigation expense, pay damages, delay product shipments, re-engineer our products or acquire licenses to
the claimants intellectual property. We may be unable to develop non-infringing technology or to obtain licenses on commercially reasonable terms. We expect that these claims may become more common as the number of products in the network
management industry increases and the functionality of these products further overlaps. If a claimant is successful in a lawsuit arising from such a claim, it could have a material adverse effect on our business. Adverse publicity related to any
intellectual property litigation also could harm (i) the sale of our products and damage our competitive position; (ii) the market for our common stock; and (iii) our ability to obtain additional capital, lines of credit or other borrowings on terms
acceptable to us.



We may not be able to comply with the requirements of
Section 404 of the Sarbanes-Oxley Act.



Beginning with
the year ended December 31, 2004, Section 404 of the Sarbanes-Oxley Act of 2002 will require us to include an internal control report of management with our Annual Report on Form 10-K, which is to include managements assessment of the
effectiveness of our internal control over financial reporting as of the end of the fiscal year. That report will also be required to include a statement that our independent auditors have issued an attestation report on both managements
assessment of our control over financial reporting and on the operating effectiveness of our internal control over financial reporting.



In order to achieve compliance with Section 404 within the prescribed period, management has adopted a detailed project work plan to assess the adequacy
of our internal control over financial reporting, remediate any control deficiencies that have been identified, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for
internal control over financial reporting. However, we may not be able to complete in a timely manner the work necessary for management to issue its management report and may not be able to report that our internal control over financial reporting
is effective. In addition, we can give no assurance that our independent auditors will be able to issue unqualified attestation reports on either managements assessment or on the operating effectiveness of our internal control over financial
reporting.



We may experience difficulties in migrating customers to the
new Visual UpTime Select product suite.



Visual UpTime
Select is based on a new licensing model and includes significant new technological innovations. We have sales and technical obstacles to overcome related to upgrading Visual UpTime customers to Visual UpTime Select. These obstacles
may delay new orders, slow product deployment or result in other unforeseen challenges with otherwise negative impacts.



We may not be able to obtain critical hardware components.



Our contract manufacturers purchase a number of critical components from vendors for which alternative sources are not currently available. Delays or
interruptions in the supply of these components could result in delays or reductions in product shipments. The purchase of these components from outside suppliers on a sole source basis subjects us to risks, including the continued availability of
supplies, price increases and potential quality assurance problems. While alternative suppliers may be available, these suppliers must be identified and qualified. We cannot be certain that any such suppliers will meet



27



---

##### Table of Contents

its required qualifications or that alternative suppliers can be identified in a timely fashion, if at all. Our contract
manufacturers may not be able to obtain sufficient quantities of these components on the same or substantially the same terms. Consolidations involving suppliers could further reduce the number of component alternatives and affect the cost of such
supplies. An increase in the cost of such supplies could make our products less competitive. Production delays, lower margins or less competitive product pricing could have a material adverse effect on our business and results of operations.



We rely on two firms for contract manufacturing services.



We have outsourced the manufacture of the ASE to two
contract manufacturing firms. We derive a substantial portion of our revenue from the sale of ASEs. A contract manufacturer could decide to reduce or eliminate the amount of credit extended to us or to suspend the shipment of products due to
concerns about our financial condition or credit and inventory risk.



If we are required to establish alternative contract manufacturers, there can be no assurances that we would be able to do so, or on acceptable terms. If we were required to replace our contract manufacturers, we could experience
substantial production delays and be required to pay substantially higher prices in order to complete delivery of customers orders. Such a delay or price increase could have a material adverse effect on our revenue and gross profit.



Our access to the SVB line of credit may be limited.



Our access to the SVB line of credit, unavailable until the Debentures
are fully repaid, may be limited if we have an insufficient borrowing base or if we cannot meet the financial and other covenants required by the facility. Under those circumstances, there can be no assurance that additional capital will be
available, or available on terms that are reasonable or acceptable to us, and our business and financial condition may be materially and adversely affected.



Substantial dilution to our common stockholders could result if we are required to raise additional capital through the sale of equity below certain price
thresholds.



Debentures outstanding of $9.0 million
are convertible into 2,559,509 shares of our common stock at the rate of $3.5163 per share and the associated warrants are exercisable for 828,861 shares of our common stock at a price of $4.2755 per share. The Debentures contain full
ratchet anti-dilution price protection. This means that if we issue additional shares of common stock in connection with a financing or under other circumstances at a price lower than $3.5163 per share, the Debentures would become convertible
into a greater number of shares of common stock than they are today. Issuances of common stock that do not trigger this anti-dilution protection include: issuances as part of an acquisition or strategic investment, issuances under our stock
incentive plan or employee stock purchase plan, or issuances as part of a public offering of more than $30.0 million.



The warrants are subject to weighted average anti-dilution protection which would decrease the exercise price and increase the number of shares issuable
under the warrants. These changes would be determined once the total investment amount and price per share of any future equity issuance were known.



We have an accumulated deficit of $473.8 million.



Our operating losses since 2000 plus the effects of impairment and restructuring charges, amortization of intangible assets and the write-off of
in-process research and development have resulted in an accumulated deficit of $473.8 million at September 30, 2004. This accumulated deficit could affect our ability to raise equity financing, arrange bank financing or arrange credit from suppliers
on reasonable or acceptable terms.

##### Table of Contents

We may not be profitable in the future.



Our ability to generate operating income in the future is dependent on our success in growing revenue and managing operating
expenses. Market conditions, competitive pressures, and other factors beyond our control, may adversely affect our ability to adequately sustain revenue in the future. In particular, our ability to sustain revenue may be negatively affected by our
dependence on our service provider customers. Pressure on capital expenditures and the decline of the telecommunications industry may delay the roll-out of new services based on our products offered by our service provider customers. Any potential
reduction in demand for value added services or products, which our products support, from the service providers customers, directly impacts the purchase volume of our products and may impact our ability to sustain revenue. While we were
profitable in the three months ended September 30, 2004, we may be required to reduce operating expenses if future revenue projections fall short of expectations. Our operating expenses include substantial fixed components which cannot be reduced
quickly. If anticipated revenue levels are below expectations, operating results are likely to be materially and adversely affected because we may not be able to reduce operating expenses on a timely basis.



We are highly dependent on sales to telecommunications service providers.



Our primary sales and marketing strategy has
predominantly revolved around sales to telecommunications service providers. We expect that a significant portion of our revenue in 2004 will be attributable to sales of Visual UpTime, Visual UpTime Select and Visual IP InSight to service
providers. The loss of any one of our service provider customers, which together have historically provided a majority of our revenue, could result in a substantial loss of revenue that could have a material adverse effect on our business and
results of operations. 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 possibility that existing service
providers may merge or fail may further reduce their numbers. Furthermore, the small number of network service providers 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 in any given quarter. Our anticipated dependence on sizable orders from a limited number of service provider customers will make the relationship between us and each service provider
critically important to our business. Further, because our agreements do not contain minimum purchase requirements, there can be no assurance of significant business with our service provider customers on an ongoing basis. With the introduction of
Visual UpTime Select, we anticipate that we will see growth in revenue from our value added reseller channel, although there can be no assurance that such growth will occur.



Our long sales cycle, which has had a median length of approximately five to six months, requires us to expend significant resources
on potential sales opportunities that may never be consummated.



Our sales cycles are relatively long because large enterprises, our target end-user market, frequently experience delays in making significant capital expenditures on complicated systems. For enterprise customers, our
historical sales cycle has a median of approximately five to six months. This extended cycle increases the risk that a potential customer might lower its capital expenditures or change product functionality requirements during the sales process.
Because we are required to commit substantial sales and marketing resources during this extended time period without any assurance of consummating an eventual sale, we risk incurring significant expense without generating any associated revenue.



Failure to adapt to rapid technological change could adversely affect
our ability to compete effectively.



The market for
our products is characterized by rapid changes, including continuing advances in technology, frequent new product introductions, changes in customer



29



---

##### Table of Contents

requirements and preferences and changes in industry standards. If we are unable to develop and introduce new products
and product enhancements in a timely fashion that accommodate future changes, we will likely lose customers and business which could have a material adverse effect on our business, financial condition and results of operations. The introduction of
new technologies, advances in techniques for network services, the integration of service level management functionality into other network hardware components and improvements to the infrastructure of the Internet could render our products obsolete
or unmarketable. There can be no assurance that (i) there will continue to be a need for our products; (ii) our existing products will continue to compete successfully; (iii) our future product offerings will keep pace with the technological changes
implemented by our competitors; (iv) our products will satisfy evolving industry standards or preferences of existing or prospective customers; or (v) we will be successful in developing and marketing products for any future technology.



We face growing competition from several market segments that could make it
difficult for us to acquire and retain customers.



We
face competition from several market segments whose functionality our products integrate. We expect competition in each of these market segments to intensify in the future. Our primary current competitors include, or in the future may include, the
following: Adtran, Brix, Concord, Kentrox, Lucent Technologies, NetScout, Packeteer, and Paradyne. Our competitors vary in size and in the scope and breadth of the products and services that they offer. While we intend to compete by offering
superior features, performance, reliability and flexibility at competitive prices and on the strength of our relationships with service providers, many of these competitors have greater financial, technical, marketing and other resources than us,
and some have well-established relationships with our current and potential customers. As a result, these competitors may be able to respond to new or emerging technologies and changes in customer requirements more effectively than us, or devote
greater resources than us to the development, promotion and sale of products. In addition, we believe that competitors from one or more of our market segments could partner with each other to offer products that supply functionality approaching that
provided by Visual UpTime Select. Increased competition may result in price reductions, reduced profitability and loss of market share, any of which could have a material adverse effect on our business and results of operations.



Errors in our products or services could discourage customers and damage our
reputation.



Products and services as complex as those
we offer may contain undetected errors or failures when first introduced or as new versions are released. There can be no assurance that, despite testing by us and by current and potential customers, errors will not be found in new products and
services until commercial shipments have commenced. Such errors can substantially delay the time until we are able to generate revenue from new product releases and could force us to divert additional development resources to correct the errors. If
such errors are detected after shipments have been made, then our reputation may be damaged, and we may incur substantial costs covering warranty claims.



In our research and development spending plan, we allocate approximately twenty percent of the engineering budget for sustaining issues.
Sustaining issues include fixing problems in released products that were not identified in the development and testing cycle. If during a given period, problems are found that cause the allocation of more than twenty percent of our
resources to fixing these problems, then the next round of product feature releases can be delayed by this diversion of resources.



We have anti-takeover protections that may delay or prevent a change in control that could benefit our stockholders.



Terms of our certificate of incorporation and bylaws make it more difficult
for another individual or company to acquire control of our company, even if a change of control would benefit our stockholders. These terms include:



| |  | our board of directors, without stockholder approval, may issue up to 5,000,000 shares of preferred stock on terms that they determine. This preferred stock could be issued quickly
with terms that delay or prevent the change in control of our company, make removal of management more difficult or depress the price of our stock;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



30



---

##### Table of Contents

| |  | certain provisions of our certificate of incorporation and bylaws and of Delaware law could delay or make more difficult a merger, tender offer or proxy contest;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law which prohibits a publicly held Delaware corporation from engaging in a
business combination with an interested stockholder for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a
prescribed manner;
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | our board of directors is staggered so that only a portion of its members are elected each year;
| | - | --------------------------------------------------------------------------------------------------



| |  | only our board of directors, our chairman of the board, our president, or stockholders holding a majority of our stock can call special stockholder meetings; and
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | special procedures must be followed in order for stockholders to present proposals at stockholder meetings.
| | - | -----------------------------------------------------------------------------------------------------------



In addition, the outstanding Debentures may become immediately due and
payable upon a change of control, which could have the effect of discouraging an acquisition that might otherwise benefit our stockholders.



Item 3. Qualitative and Quantitative Disclosure About Market Risk



The Debentures bear interest at a fixed annual rate of 5%. We are also exposed to market risk from changes in interest rates. Our investment policy
restricts us to investing only in investment-grade securities. A failure of these investment securities to perform at their historical levels could reduce the interest income realized by us.



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 United States dollars. However, if we commence selling material volumes of product to such customers at prices not denominated in United
States 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 the Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures
(as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that as of September 30, 2004, our disclosure controls and procedures are effective.
There have been no significant changes in our internal control or in factors that could significantly affect internal control or in factors that could significantly affect internal controls subsequent to the date we carried out this evaluation.

PART II  OTHER INFORMATION



Item 1. Legal Proceedings



In
January 2004, we received notice that a lawsuit had been filed by Paradyne Networks, Inc. (Paradyne), of Largo, Florida, in the United States District Court for the Middle District of Florida, Tampa Division (the Florida
Court), seeking damages, and injunctive and declaratory relief, for our alleged infringement of patents owned by Paradyne Corporation, a subsidiary of Paradyne.



On May 14, 2004, the Florida Court granted our motion to dismiss the case for lack of subject matter jurisdiction and denied
Paradynes motion for leave to amend its complaint and its motion for preliminary injunction. Paradyne did not appeal the decision.



In a related matter, one of our subsidiaries, Visual Networks Operations, Inc., filed a lawsuit in United States District Court for the District of
Maryland, Southern Division (the Maryland Court), against Paradyne Corporation. This lawsuit requests declaratory judgment that Visual UpTime and Visual IP InSight do not infringe certain patents owned by Paradyne Corporation and that
those patents are invalid and unenforceable and alleges that Paradynes assertion of its patents against us is baseless and has been for the sole purpose of obtaining an unfair competitive advantage, and that Paradyne has infringed certain
patents own by us. Paradyne filed counterclaims alleging the Visual Networks Operations, Inc. infringement of its patents, mirroring the Florida claims. On October 15, 2004, Paradyne Corporation filed amended counterclaims, adding allegations of
willful patent infringement and unenforceability of two of our patents in the lawsuit. The Maryland lawsuit presently is in the fact discovery phase of the litigation. The Maryland Court has scheduled a hearing concerning patent claim construction
for February 7, 2005. A trial date has not yet been scheduled.



Despite managements belief that our products do not infringe upon the Paradyne subsidiarys patents and that Paradynes claims are frivolous and without merit, the conduct of the litigation is expensive and may divert our
resources from other activities, which could have a material adverse effect on our business and results of operations. At this point in the litigation, the likelihood of any outcome cannot be determined and the adverse effect of any finding cannot
be estimated.



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