                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     THE COMPANY

     We are a global provider of communications software solutions that enable
     carriers to more effectively design, deploy, diagnose, monitor and manage
     communications networks that carry signaling information used to control
     and deliver communications sessions and services. These communications
     sessions include phone calls, dial-up Internet access and other service
     transactions or sessions. Our solutions also address the fundamental
     business needs of communications carriers, such as improved billing,
     targeted sales and marketing, fraud prevention and enhanced routing. We
     provide these comprehensive offerings through our network intelligence,
     business intelligence and diagnostics solutions.

     CONSOLIDATION

     The consolidated financial statements include the accounts of our
     wholly-owned subsidiaries. Intercompany balances and transactions have been
     eliminated.

     UNAUDITED INTERIM FINANCIAL STATEMENTS

     We have prepared the accompanying unaudited consolidated financial
     statements in accordance with accounting principles generally accepted in
     the United States for interim financial information and the instructions to
     Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not
     include all of the information and footnotes required by accounting
     principles generally accepted in the United States for complete financial
     statements. In our opinion, all adjustments necessary, consisting solely of
     normal recurring adjustments, for a fair statement of the results for the
     interim periods presented have been included. These financial statements
     should be read in conjunction with the audited financial statements and
     related notes for the three years ended December 31, 2000, included in our
     Annual Report on Form 10-K filed with the Securities and Exchange
     Commission, or SEC, on March 26, 2001. Financial results for the three- and
     six-month periods ended June 30, 2001 are not necessarily indicative of the
     results that may be expected for any other interim period or for the year
     ending December 31, 2001.

     CASH AND CASH EQUIVALENTS

     All highly liquid securities with original maturities of three months or
     less are classified as cash equivalents. The carrying value of cash
     equivalents approximates fair market value.

     INVENTORIES

     Inventories are valued at the lower of standard cost, which approximates
     actual cost determined on a first-in, first-out basis, or market. At June
     30, 2001 and December 31, 2000, inventories consisted of the following (in
     thousands):

     REVENUE RECOGNITION

     Effective January 1, 2000, we adopted Statement of Position, or SOP, 98-9,
     MODIFICATION OF SOP 97-2, `SOFTWARE REVENUE RECOGNITION' WITH RESPECT TO
     CERTAIN TRANSACTIONS, which did not require a significant change to our
     revenue recognition policies. In December 1999, the SEC issued Staff
     Accounting Bulletin, or SAB, No. 101, REVENUE RECOGNITION IN FINANCIAL
     STATEMENTS, which we adopted in the fourth quarter of 2000 retroactive to
     January 1, 2000. The adoption of SAB 101 did not materially affect our
     revenue recognition policies.

     We derive revenues primarily from the sale of products and software license
     fees as well as services, which include product installation, product
     integration, training, warranty and product support services.

     Except as otherwise discussed below, revenues from product and license fees
     are recognized in the period we have completed all hardware manufacturing
     and/or software development to contractual specifications, factory testing
     has been completed, the product has been shipped to the customer, the fee
     is fixed and determinable and collection is considered probable. When we
     have significant obligations subsequent to shipment, for example,
     installation and system integration, revenues are recognized when there are
     no significant unfulfilled obligations. Revenues from arrangements that
     include significant acceptance terms are recognized when acceptance has
     occurred.

     Revenues for fixed-priced contracts that require significant software
     development and are generally in duration in excess of nine months are
     recognized using the percentage-of-completion method. Revenues from these
     contracts are recognized upon attainment of scheduled performance
     milestones. Anticipated losses on fixed-priced contracts are recognized
     when estimable.

     Revenues from product installation, product integration and other services,
     excluding product support services, are recognized when the services have
     been completed.

     We offer our customers product support services, which include the
     correction of software problems, telephone access to our technical
     personnel and the right to receive unspecified product updates, upgrades
     and enhancements, when and if they become available. Revenues from these
     services, including product support services included in initial licensing
     fees, are recognized ratably over the contract period. Product support
     services included in the initial licensing fee are allocated from the total
     contract amount based on the relative fair value of these services
     determined using vendor-specific objective evidence, or VSOE.

     Deferred revenues represent amounts billed to customers, but not yet
     recognized as revenue. Unbilled receivables represent amounts recognized as
     revenue, but not yet billed to customers.

     ACCOUNTING ESTIMATES

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

NOTE 2 - RELATED PARTY TRANSACTION

     Effective January 1, 2000, we sold our membership interest in Inet Global
     Research, L.L.C., to an entity controlled by a related party for a cash
     purchase price of $82,000. No gain or loss was recorded for the sale. This
     entity is currently performing services for us for which it is paid a
     monthly fee per dedicated full-time programmer plus reimbursement of
     reasonable business expenses. We paid approximately $835,000 for these
     services for the six months ended June 30, 2001, and approximately $180,000
     for the six months ended June 30, 2000.

                                  Page 8 of 26


NOTE 3 - RESTRUCTURING

     In March 2001, we recorded a restructuring charge of $526,000 primarily
     related to a workforce reduction of approximately 40 employees. The
     reduction affected all areas of the company. The charge primarily consisted
     of employee severance costs, professional fees and outplacement services.
     At June 30, 2001, the balance of these costs that remained to be paid
     totaled approximately $164,000.

     In May 2001, we announced our decision to refocus our strategy and
     streamline operations to reduce our cost structure in response to the
     generally weakened economic environment and changing demand characteristics
     in some of our markets. As part of this decision, we discontinued all
     efforts with respect to our softswitch offering, VIA-TM-, and reduced our
     workforce by approximately 115 employees. The reduction affected all areas
     of the company. We recorded a restructuring charge of approximately $1.7
     million, which consisted of employee severance costs of approximately $1.1
     million, professional fees and outplacement services of approximately
     $300,000 and the write-off of assets related to the VIA softswitch product
     of approximately $300,000. At June 30, 2001, the balance of these costs
     that remained to be paid totaled approximately $700,000.

     For the both the three- and six-month periods ended June 30, 2001, revenues
     from Deutsche Telekom AG accounted for more than 10% of total revenues. For
     the same prior-year periods, revenues from British Telecom and Worldcom
     each accounted for more than 10% of total revenues.

     We have no significant long-lived assets deployed outside of the United
     States.

NOTE 7 - DERIVATIVES

     On January 1, 2001, we adopted Statement of Financial Accounting Standards,
     or SFAS, No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING
     ACTIVITIES, as amended. SFAS 133 requires that all derivatives be
     recognized at fair value on the balance sheet, and that the corresponding
     gains or losses be included in comprehensive income, depending on the type
     of hedging relationship that exists. Adoption of this standard did not have
     a material effect on our financial statements.

     OVERVIEW

     We were founded in 1989 and during the early stages of our operations we
     focused primarily on developing and selling diagnostics tools for a
     predecessor to the Signaling System #7, or SS7, signaling protocol. As the
     telecommunications industry increasingly adopted SS7, we shifted our focus
     to developing and deploying SS7-based solutions as well as broadening our
     product offerings. Our diagnostics solution, Spectra, was first introduced
     in December 1990 and is currently in its tenth generation release.
     Beginning in 1993, we focused a significant portion of our product
     development efforts on developing a complete monitoring and surveillance
     solution for SS7 networks, culminating in the introduction of our network
     intelligence solution, the GeoProbe-TM-, in late 1995. Beginning in late
     1999 and through 2000, we introduced a suite of business intelligence
     solutions called IT:seven-TM-. These applications enable carriers to
     protect and generate additional revenues within their networks and at
     interconnection boundaries. In June 2001, we introduced our next-generation
     diagnostics solution, Spectra2 MG-TM-. We continue to focus significant
     resources on the development of enhancements, new features and new
     applications for our existing product areas.

     Historically, we have generated substantially all of our revenues from
     sales of our network intelligence and diagnostics solutions. Specifically,
     revenues attributable to the GeoProbe have represented a majority of our
     total revenues since 1998. Although we expect diagnostics revenues to
     continue to represent a significant portion of total revenues for the
     foreseeable future, these revenues are expected to continue to decline as a
     percentage of total revenues as a result of higher growth rates for the
     network intelligence and business intelligence offerings. Our remaining
     revenues are derived from services relating to these and other products.
     These services include product installation, product integration, training,
     warranty and product support.

     RESULTS OF OPERATIONS

     The following table sets forth, for the periods presented, certain data
     derived from our unaudited consolidated statements of operations expressed
     as a percentage of total revenues. The financial results for the three- and
     six-month periods ended June 30, 2001 are not necessarily indicative of the
     results that may be expected for any other interim period or for the year
     ending December 31, 2001.

     REVENUES

     PRODUCT AND LICENSE FEES. Revenues from product and license fees decreased
     43.1% to $18.5 million for the three months ended June 30, 2001 from $32.6
     million for the three months ended June 30, 2000. For the six months ended
     June 30, 2001, revenues from product and license fees decreased 28.7% to
     $44.5 million from $62.5 million for the six months ended June 30, 2000.
     The decline in revenues from product and license fees is primarily
     attributable to fewer GeoProbe and IT:seven installations being completed
     to the point of enabling revenue recognition and a decrease in demand
     for our diagnostics products, both of which are primarily driven by the
     slowdown in the economy.

     SERVICES. Revenues from services increased 29.1% to $5.5 million for the
     three months ended June 30, 2001 from $4.2 million for the three months
     ended June 30, 2000. For the six months ended June 30, 2001, revenues from
     services increased 49.3% to $10.9 million from $7.3 million for the six
     months ended June 30, 2000. The increase in services revenues is primarily
     related to the recurring fees associated with product support services
     realized from our larger installed customer base.

     CONCENTRATION OF REVENUES. For both the three- and six-month periods
     ended June 30, 2001, revenues from Deutsche Telekom AG accounted for
     more than 10% of total revenues. For the same prior-year periods,
     revenues from British Telecom and Worldcom each accounted for more than
     10% of total revenues.

     INTERNATIONAL REVENUES. For the three months ended June 30, 2001,
     international revenues accounted for 57.4% of total revenues compared to
     63.7% of total revenues for the three months ended June 30, 2000. For the
     six months ended June 30, 2001, international revenues accounted for 62.0%
     of total revenues compared to 52.2% of total revenues for the six months
     ended June 30, 2000. Variations in the percentage of total revenues derived
     from international markets may occur given that a large percentage of our
     revenues are typically derived from a small number of customers, the
     specific make up of which varies from one quarter to the next.

                                 Page 12 of 26


     COST OF REVENUES

     PRODUCT AND LICENSE FEES. Cost of product and license fees consists
     primarily of hardware expenses and personnel and overhead costs related to
     the manufacturing, integration and installation of our products. Cost of
     product and license fees was $9.0 million, or 37.7% of total revenues, for
     the three months ended June 30, 2001, compared to $7.5 million, or 20.4% of
     total revenues, for the three months ended June 30, 2000. The increase in
     absolute dollars is primarily related to a $867,000 charge to cost of goods
     sold for excess and obsolete materials and canceled purchase commitments as
     well as increased installation related costs on a per project basis. The
     increase as a percentage of total revenues was primarily attributable to
     the charge to cost of goods sold for excess and obsolete materials and
     canceled purchase commitments as well as the decreased level of revenues.

     For the six months ended June 30, 2001, cost of product and license fees
     was $19.1 million, or 34.4% of total revenues, compared to $13.5 million,
     or 19.4% of total revenues, for the six months ended June 30, 2000. The
     increase in absolute dollars resulted primarily from increases in hardware
     costs attributable to our continued support of our legacy systems and to
     hardware design changes required to support new version releases. Also, in
     certain expansions, additional hardware is required to make the system
     compatible with the current generation of the GeoProbe platform. The
     increase in absolute dollars is also attributable to the charge to cost of
     goods sold for excess and obsolete materials and canceled purchase
     commitments. The increase as a percentage of total revenues was primarily
     attributable to that charge as well as the decreased level of revenues.

     SERVICES. Cost of services consists of expenses, primarily personnel costs,
     related to product support, training, and warranty and non-warranty work.
     Cost of services was $2.1 million, or 8.6% of total revenues, for the three
     months ended June 30, 2001 and $2.1 million, or 5.7% of total revenues, for
     the three months ended June 30, 2000. Cost of services was $4.7 million, or
     8.4% of total revenues, for the six months ended June 30, 2001 and $3.9
     million, or 5.5% of total revenues, for the six months ended June 30, 2000.
     Cost of services as a percentage of total revenues has historically
     fluctuated on a period-to-period basis based upon the relative mix of
     product support, training and warranty and non-warranty work for the
     period.

     OPERATING EXPENSES

     RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses
     consist primarily of personnel, contract labor, travel and facilities
     costs. These expenses increased to $9.9 million for the three months ended
     June 30, 2001 from $7.8 million for the three months ended June 30, 2000.
     The increase in absolute dollars was primarily due to increased staffing
     dedicated to research and development activities and higher wage levels
     required to retain qualified technical and engineering personnel. Research
     and development expenses as a percentage of total revenues were 41.3% for
     the three months ended June 30, 2001 and 21.3% for the three months ended
     June 30, 2000. The increase as a percentage of total revenues was
     attributable to the increase in staffing dedicated to research and
     development activities as well as a decreased level of revenues.

     For the six months ended June 30, 2001, research and development expenses
     increased to $21.6 million from $14.9 million for the comparable prior-year
     period. The increase in absolute dollars was primarily due to increased
     staffing levels, higher wage levels required to retain qualified technical
     and engineering personnel and outsourced research and development. Research
     and development expenses as a percentage of total revenues were 39.0% for
     the six months ended June 30, 2001, and 21.4% for the six months ended June
     30, 2000. The increase as a percentage of total revenues was attributable
     to the increase in staffing dedicated to research and development
     activities and the decreased level of revenues.

     Software development costs are expensed as incurred until technological
     feasibility has been established, at which time subsequent costs are
     permitted to be capitalized until the product is available for general
     release to customers. To date, either the establishment of technological
     feasibility of our products has substantially coincided with their general
     release, or costs incurred subsequent to the achievement of

                                 Page 13 of 26


     technological feasibility have not been material. As a result, software
     development costs qualifying for capitalization have been insignificant,
     and we have not capitalized any software development costs.

     SALES AND MARKETING EXPENSES. Sales and marketing expenses consist
     primarily of personnel, travel, facilities, distributor commissions, and
     expenses for trade shows and advertising. These expenses increased to $5.1
     million for the three months ended June 30, 2001 from $4.0 million for the
     three months ended June 30, 2000. The increase in absolute dollars was
     primarily due to increased personnel costs related to increased average
     headcount. Sales and marketing expenses as a percentage of total revenues
     were 21.4% for the three months ended June 30, 2001 and 10.8% for the three
     months ended June 30, 2000. The increase as a percentage of total revenues
     was attributable to the combination of the increase in personnel costs
     related to increased average headcount and the decreased level of revenues.

     Sales and marketing expenses increased to $10.9 million for the six months
     ended June 30, 2001 from $8.2 million for the six months ended June 30,
     2000. The increase was primarily due to increased personnel costs related
     to increased average headcount and, to a lesser extent, increased
     international sales activities and increased promotional activities. Sales
     and marketing expenses as a percentage of total revenues were 19.6% for the
     six months ended June 30, 2001, and 11.8% for the six months ended June 30,
     2000. The increase as a percentage of total revenues was attributable to
     the combination of the increase in personnel costs related to increased
     average headcount and the decreased level of revenues.

     GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
     consist primarily of personnel, facilities and other costs of our finance,
     administrative and executive departments, as well as professional fees and
     expenses associated with legal and accounting requirements. These expenses
     decreased to $2.5 million for the three months ended June 30, 2001 from
     $3.0 million for the three months ended June 30, 2000. The decrease in
     absolute dollars was primarily related to decreased professional fees and
     decreased staffing levels. General and administrative expenses as a
     percentage of total revenues were 10.5% for the three months ended June 30,
     2001 and 8.2% for the three months ended June 30, 2000. The increase as a
     percentage of total revenues was attributable to the decreased level of
     revenues.

     General and administrative expenses decreased to $5.3 million for the six
     months ended June 30, 2001 from $5.5 million for the six months ended June
     30, 2000. The decrease was primarily related to decreased professional
     fees. General and administrative expenses as a percentage of total revenues
     were 9.5% for the six months ended June 30, 2001 and 7.8% for the six
     months ended June 30, 2000. The increase as a percentage of total revenues
     was attributable to the decreased level of revenues.

     RESTRUCTURING COSTS. We recorded a restructuring charge for the three
     months ended March 31, 2001 of $526,000 primarily related to a workforce
     reduction of approximately 40 employees. The reduction affected all areas
     of the company. The charge primarily consisted of employee severance costs,
     professional fees and outplacement services. At June 30, 2001, the balance
     of these costs that remained to be paid totaled approximately $164,000.

     In May 2001, we announced our decision to refocus our strategy and
     streamline operations to reduce our cost structure in response to the
     generally weakened economic environment and changing demand characteristics
     in some of our markets. As part of this decision, we discontinued all
     efforts with respect to our softswitch offering, VIA, and reduced our
     workforce by approximately 115 employees. The reduction affected all areas
     of the company. We recorded a restructuring charge for the three months
     ended June 30, 2001 of approximately $1.7 million, which consisted of
     employee severance costs of approximately $1.1 million, professional fees
     and outplacement services of approximately $300,000 and the write-off of
     assets related to the VIA softswitch of approximately $300,000. At June 30,
     2001, the balance of these costs that remained to be paid totaled
     approximately $700,000.

     OTHER INCOME

     Other income is primarily interest income earned on our cash and cash
     equivalents. Other income was $1.5 million for the three months ended June
     30, 2001 compared to $2.1 million for the three months ended June 30, 2000.
     Other income was $3.4 million for the six months ended June 30, 2001
     compared to

                                 Page 14 of 26


     $3.9 million for the six months ended June 30, 2000. The decrease for both
     the three- and six-month periods ended June 30, 2001 is attributable to the
     overall decrease in interest rates.

     PROVISION FOR INCOME TAXES

     The effective income tax rate for both the three and six months ended
     June 30, 2001 was a 36.0% benefit compared to a 34.0% provision for both
     the three and six months ended June 30, 2000.

     LIQUIDITY AND CAPITAL RESOURCES

     Since our inception, we have funded our operations and met our capital
     expenditure requirements primarily through cash flows from operations. We
     had working capital of $162.7 million at June 30, 2001 and $167.2 million
     at December 31, 2000. At June 30, 2001, we had $146.2 million in cash and
     cash equivalents, an increase of $14.8 million from $131.4 million in cash
     and cash equivalents at December 31, 2000. The increase in cash and cash
     equivalents is primarily attributable to a decrease in trade accounts
     receivable due to collections on these accounts, receipt of an income tax
     refund and proceeds from the issuance of common stock upon the exercise of
     stock options and purchases under our employee stock purchase plan.

     We have a credit facility with a bank providing for borrowings of up to
     $10.0 million. This credit facility will expire on August 15, 2001. Up to
     $5.0 million may be utilized to support letters of credit. The per annum
     usage fee on unused portions of the line is 0.125%. At our option,
     borrowings under this facility bear interest at either (i) the bank's prime
     rate reduced by up to 0.50% or (ii) the London interbank offered rate, or
     LIBOR, as adjusted to meet specified Federal Reserve requirements with
     respect to Eurocurrency liabilities, increased by up to 1.50%. This
     facility is collateralized by our accounts receivable, inventories and
     property and equipment. The credit facility restricts the payment of cash
     dividends without the bank's consent and includes covenants requiring us to
     maintain specified financial ratios and to not incur net losses in two
     consecutive quarters. At June 30, 2001, no amounts were outstanding under
     the credit facility and we had no outstanding letters of credit.

     Net cash provided by operating activities was $18.7 million for the six
     months ended June 30, 2001, compared to $12.0 million during the same
     period in 2000. Net cash provided by operating activities resulted
     primarily from a decrease in trade accounts receivable due to collections
     of these accounts and a decrease in income taxes receivable.

     Net cash used in investing activities was $6.1 million for the six months
     ended June 30, 2001 compared to $3.2 million during the same period in
     2000. Net cash used in investing activities for both periods related to
     purchases of property and equipment.

     Net cash provided by financing activities was $2.1 million for the six
     months ended June 30, 2001 and $1.9 million during the same period of 2000.
     Net cash provided by financing activities in both periods resulted from
     proceeds from the issuance of common stock upon the exercise of stock
     options and purchases under our employee stock purchase plan.

     In January 2000, we signed a ten-year lease agreement for our corporate
     headquarters facility in Richardson, Texas. We estimate that our remaining
     commitment for leasehold improvements for this office space is less than
     $100,000. We have no other material commitments for capital expenditures.
     Our current cash balances are sufficient to cover these estimated capital
     expenditures.

     Any material acquisition or joint venture could result in a decrease in our
     working capital, depending on the amount, timing and nature of the
     consideration to be paid. Absent any such acquisition or joint venture, we
     anticipate that current cash balances, potential cash flows from operations
     and available borrowings under any revolving credit facility then in place
     will be sufficient to meet our anticipated cash needs for working capital,
     capital expenditures and other activities for at least the next 12 months.
     Thereafter, if current sources are not sufficient to meet our needs, we may
     seek additional equity or debt financing. In addition, any material
     acquisition of complementary businesses, products or technologies or

                                 Page 15 of 26


     material joint venture could require us to obtain additional equity or debt
     financing. There can be no assurance that additional financing would be
     available on acceptable terms, if at all.

     RISK FACTORS

     OUR QUARTERLY FINANCIAL RESULTS FLUCTUATE AND ARE DIFFICULT TO PREDICT.

     Since our future financial results are likely to vary significantly from
     quarter to quarter, you should not rely on our results of operations during
     any particular quarter as an indication of our future performance in any
     fiscal year or quarterly period. Our quarterly financial results have
     varied significantly in the past and are likely to vary significantly from
     quarter to quarter in the future based on a number of factors, many of
     which are outside of our control. These factors include but are not limited
     to:

          o    the size, timing and terms of specific orders by customers;

          o    competition;

          o    the degree of market acceptance of new products and technologies
               introduced by us and our competitors;

          o    the mix of products and services sold by us;

          o    the timing of product shipments and product installations by us;

          o    the timing of customer acceptance of products we deliver to them;

          o    the capital spending patterns of our customers;

          o    the mix of domestic and international sales;

          o    the mix of new installations and system expansions;

          o    the timing of and level of our expenses;

          o    the relative percentages of products sold through our direct and
               indirect sales channels;

          o    customer order deferrals in anticipation of enhancements or new
               products;

          o    the timing of and level of our investments in research and
               development activities;

          o    changes in, and our ability to implement, our strategy;

          o    changes in the availability or cost of materials needed to
               produce our products;

          o    the progress and timing of the privatization and restructuring of
               telecommunications markets and the worldwide deregulation of the
               international telecommunications industry;

          o    defects and product quality problems;

          o    intellectual property disputes;

          o    expansion of and risks associated with our international
               operations; and

          o    changes in general economic conditions.

                                 Page 16 of 26


     Furthermore, a large portion of our operating expenses, including rent and
     salaries, is largely fixed in nature. Accordingly, if revenues are below
     expectations, our financial results are likely to be adversely and
     disproportionately affected because these operating expenses are not
     variable in the short term, and cannot be quickly reduced to respond to
     unanticipated decreases in revenues.

     The amount of revenues associated with particular product sales can vary
     significantly. The deferral or loss of one or more individually significant
     sales could harm our financial results in a particular quarter.

     Our financial results also are likely to fluctuate due to factors that
     impact our current and prospective customers. Expenditures by customers
     tend to vary in cycles that reflect overall economic conditions and
     individual budgeting and buying patterns and, in some cases, the ability of
     some of our customers to obtain the financing they require to make capital
     expenditures. Our business has been adversely affected by a softening
     economy and we would be further harmed by a further decline in the economic
     prospects of our customers or the economy in general. These adverse
     economic conditions could be expected to alter current or prospective
     customers' capital spending priorities or budget cycles, or extend our
     sales cycle with respect to some of our customers. Our business also could
     be harmed by changes in customer spending patterns reflecting industry
     trends. In addition, our financial results historically have been
     influenced by seasonal fluctuations, with revenues tending to be strongest
     in the fourth quarter of each year. We believe that this seasonality has
     been due to the capital appropriation practices of many of our customers.
     We expect that in future periods this seasonal trend may contribute to our
     first quarter revenues to remain consistent with, or decrease from, the
     level achieved in the preceding quarter.

     As a result of all of the foregoing, we cannot assure you that our revenues
     will grow in future periods or that we will be profitable. In addition, in
     some future quarters our financial results again may be below the
     expectations of public market analysts. In such event, the market price of
     our common stock likely would fall.

     CONSOLIDATIONS IN THE TELECOMMUNICATIONS INDUSTRY OR A FURTHER SLOWDOWN IN
     TELECOMMUNICATIONS SPENDING COULD HARM OUR BUSINESS, FINANCIAL CONDITION
     AND RESULTS OF OPERATIONS.

     We have derived substantially all of our revenues from sales of products
     and related services to the telecommunications industry. In recent months,
     we and a number of other companies have experienced reduced spending by
     telecommunications carriers and equipment manufacturers. Our business,
     financial condition and results of operations could be materially harmed in
     the event of a further significant slowdown in this industry or in the
     event there are consolidations of our current or prospective customers.
     Slowdowns in spending often cause delays in sales and installations and
     could cause cancellations, any of which would harm our financial results in
     a particular period.

     CHANGES OR DELAYS IN IMPLEMENTATION OF OUR PRODUCTS COULD HARM OUR
     FINANCIAL RESULTS.

     Revenues for our network intelligence and business intelligence solutions
     are typically recognized upon the completion of installation, unless the
     contract provides for significant additional obligations. Customer- or
     Inet-caused delays in the commencement or completion of scheduled product
     installations, which from time to time result from site-readiness delays,
     lack of resources or other issues and lengthening of implementation
     schedules due to the introduction of new features or applications, could
     materially harm our financial results. With respect to contracts providing
     for a significant payment or performance milestone tied to customer
     acceptance or allowing customer return, termination or similar rights prior
     to acceptance, revenue will generally not be recognized until the customer
     provides acceptance. Further, for new products, we also recognize revenue
     upon acceptance until a track record of installation is achieved, after
     which revenue recognition generally is tied to completion of installation.
     In cases where the recognition of revenue is tied to customer acceptance,
     the failure or delay in receiving such acceptance could harm our expected
     financial results for a particular period.

                                 Page 17 of 26


     ANY REVERSAL OR SLOWDOWN IN DEREGULATION OF TELECOMMUNICATIONS MARKETS
     COULD MATERIALLY HARM THE MARKET FOR OUR PRODUCTS.

     Future growth in the markets for our products will depend in part on
     continued privatization, deregulation and the restructuring of
     telecommunications markets worldwide. Any reversal or slowdown in the pace
     of this privatization, deregulation or restructuring could materially harm
     the markets for our products. Moreover, the consequences of deregulation
     are subject to many uncertainties, including judicial and administrative
     proceedings that affect the pace at which the changes contemplated by
     deregulation occur, and other regulatory, economic and political factors.
     Any invalidation, repeal or modification of the requirements imposed by the
     Telecommunications Act of 1996, the local telephone competition rules
     adopted by the U.S. Federal Communications Commission to implement that Act
     or similar international regulation could materially harm our business,
     financial condition and results of operations. Furthermore, the
     uncertainties associated with deregulation have in the past, and could in
     the future, cause our customers to delay purchasing decisions pending the
     resolution of these uncertainties.

     THE SALES CYCLE FOR OUR PRODUCTS IS LONG, WHICH COULD HARM OUR QUARTERLY
     FINANCIAL RESULTS.

     Sales of our network intelligence and business intelligence products and
     solutions are made predominately to large communications service providers
     and involve significant capital expenditures and lengthy implementation
     processes. Prospective customers generally commit significant resources to
     an evaluation of our product offerings and our competitors' product
     offerings and require each vendor to expend substantial time, effort and
     money educating the prospective customer about the value of each vendor's
     solutions. Consequently, sales to this type of customer generally require
     an extensive sales effort throughout the customer's organization and final
     approval by an executive officer or other senior level employee. We
     frequently experience delays following initial contact with a prospective
     customer and expend substantial funds and management effort pursuing these
     sales. Additionally, delays associated with potential customers' internal
     approval and contracting procedures, procurement practices, testing and
     acceptance processes are common and may cause potential sales to be delayed
     or foregone. As a result of these or other factors, the sales cycle for our
     solutions is long, historically ranging from six to 12 months for our
     network intelligence and business intelligence solutions (excluding the
     cycle for subsequent applications and enhancements, which varies widely)
     and up to three months for occasional, large sales of our diagnostics
     solutions, and we have experienced lengthening sales cycles during the
     current soft economy. Accordingly, our ability to forecast the timing and
     amount of specific sales is limited, and the deferral or loss of one or
     more significant sales could materially harm anticipated financial results
     in a particular quarter, particularly if there are significant sales and
     marketing expenses associated with any deferred or lost sales.

     ANY DECREASE IN DEMAND FOR OUR PRODUCTS COULD SIGNIFICANTLY DECREASE OUR
     SALES.

     Our principal products, the GeoProbe, IT:seven and Spectra, generate
     substantially all of our revenues today and are expected to continue to
     account for substantially all of our revenues for the foreseeable future.
     Any downturn in the demand for these products would materially harm our
     business, financial condition and results of operations. We cannot assure
     you that we will be successful in developing any other products or taking
     any other steps to reduce the risk associated with any slowdown in demand
     for the GeoProbe, IT:seven and/or Spectra.

     IF THE MARKET FOR CONVERGING AND NEXT-GENERATION NETWORK SOLUTIONS FAILS TO
     DEVELOP OR GROWS MORE SLOWLY THAN WE ANTICIPATE, OUR FINANCIAL RESULTS
     COULD BE HARMED.

     Our future financial results are dependent in significant part on the
     continued viability and expansion of SS7 signaling networks, the
     convergence of the public switched telephone network, or PSTN, with new
     packet-based networks (for example, Internet protocol, or IP, and
     asynchronous transfer mode, or ATM) and the build out of next-generation
     networks. Our business, financial condition and results of operations could
     be materially harmed if the market for converging and next-generation
     network solutions fails to develop or grows more slowly than we currently
     anticipate.

                                 Page 18 of 26


     COMPETITION COULD REDUCE OUR MARKET SHARE, WHICH WOULD LIKELY HARM OUR
     BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

     The market for signaling-based communications network solutions is
     relatively new, intensely competitive, both in the U.S. and
     internationally, and subject to rapid technological change, evolving
     industry standards and regulatory developments. Competition for all of our
     solutions is expected to continue and in some cases intensify in the
     future. We compete with a number of U.S. and international suppliers that
     vary in size, and in the scope and breadth of the products and services
     offered. Certain of our competitors have, in relation to us, longer
     operating histories, larger installed customer bases, longer-standing
     relationships with customers, greater name recognition and significantly
     greater financial, technical, marketing, customer service, public
     relations, distribution and other resources. Additionally, it is possible
     that new competitors or alliances among competitors could emerge and
     rapidly acquire significant market share. As a result, these competitors
     may be able to more quickly develop or adapt to new or emerging
     technologies and changes in customer requirements, or devote greater
     resources to the development, promotion and sale of their products.
     Increased competition is likely to result in price reductions, reduced
     margins and loss of market share. The competitive pressures we face could
     materially harm our business, financial condition and results of
     operations.

     RAPID GROWTH AND EXPANSION OF OUR BUSINESS MAY STRAIN OUR RESOURCES AND
     HINDER OUR ABILITY TO IMPLEMENT OUR BUSINESS STRATEGY.

     We have historically experienced rapid and significant growth that has
     placed, and may continue to place, a significant strain on our management,
     information systems and operations. Any significant additional growth will
     require us to improve our financial, operational and management information
     and control systems and procedures.

     We anticipate that continued growth, if any, could require us to recruit
     and hire a substantial number of new employees, particularly sales and
     marketing personnel and technical personnel with signaling and IP knowledge
     and experience, both in the U.S. and internationally. Competition for
     personnel is intense, and we have at times experienced difficulty in
     recruiting qualified personnel. We historically have filled a portion of
     our new personnel needs with non-U.S. citizens holding temporary work visas
     that allow these individuals to work in the U.S. for only a limited period
     of time. Accordingly, any change in U.S. immigration policy further
     limiting the issuance of temporary work visas could adversely affect our
     ability to recruit new personnel. Furthermore, the addition of significant
     numbers of new personnel requires us to incur significant start-up
     expenses, including recruiting fees, procurement of office space and
     equipment, and initial training costs; and, we often experience low
     utilization rates with new personnel. We may be unable to successfully
     recruit or retain additional personnel as needed. In addition, the start-up
     expenses incurred in connection with the hiring of additional personnel
     could harm our future financial results.

     OUR BUSINESS DEPENDS ON RETAINING OUR EXISTING KEY PERSONNEL.

     Our business depends to a significant extent upon the continued service and
     performance of a relatively small number of key senior managers, technical
     personnel and sales and marketing personnel, few of whom are bound by an
     employment agreement. The loss of any existing key personnel, or the
     inability to attract, motivate and retain additional key personnel, could
     harm our business, financial condition and results of operations.

     WE MAY BE UNABLE TO ADAPT TO RAPID TECHNOLOGICAL CHANGE AND EVOLVING
     CUSTOMER REQUIREMENTS.

     The market for our products is characterized by rapid technological
     advances, evolving industry and customer-specific protocol standards,
     changes in customer requirements and frequent new product introductions and
     enhancements. The introduction of communications network management
     products involving superior technologies or the evolution of alternative
     technologies or new industry protocol standards could render our existing
     products, as well as products currently under development, obsolete

                                 Page 19 of 26


     and unmarketable. We believe that our future success will depend in part
     upon our ability, on a timely and cost-effective basis, to continue to:

          o    enhance our network intelligence, business intelligence and
               diagnostics solutions;

          o    develop and introduce new products for the communications network
               management market and other markets;

          o    keep pace with evolving industry protocol standards and changing
               customer needs; and

          o    achieve broad market acceptance for our products.

     We cannot assure you that we will achieve these objectives.

     OUR FUTURE SUCCESS WILL DEPEND ON OUR ABILITY TO DEVELOP NEW PRODUCTS BASED
     ON EMERGING TECHNOLOGIES.

     We expect carrier spending for legacy networks to decrease over time, which
     requires that we develop solutions for networks based on emerging packet
     technologies and standards, such as IP and ATM. These emerging technologies
     and standards are likely to be characterized by continuing technological
     developments, evolving industry standards and changing customer
     requirements. We may not successfully develop competitive products for
     these emerging technologies and standards, which could harm our business,
     financial condition and results of operations.

     Products as complex as those currently under development by us frequently
     are subject to delays, and we cannot assure you that we will not encounter
     difficulties that could delay or prevent the successful and timely
     development, introduction and marketing of these potential new products.
     Even if such potential new products are developed and introduced, we cannot
     assure you that they will achieve any significant degree of market
     acceptance. Failure to release these or any other potential new products on
     a timely basis, or failure of these or any other potential new products, if
     and when released, to achieve any significant degree of market acceptance,
     could materially harm our business, financial condition and results of
     operations.

     WE HAVE INTERNATIONAL CUSTOMERS, AND, AS A RESULT, OUR BUSINESS MAY BE
     HARMED BY POLITICAL AND ECONOMIC CONDITIONS IN FOREIGN MARKETS AND THE
     CHALLENGES ASSOCIATED WITH OPERATING INTERNATIONALLY.

     Our international operations are subject to the risks inherent in
     international business activities. We believe that continued growth, if
     any, could require expansion of our efforts in international markets. This
     expansion may be costly and time-consuming and may not generate returns for
     a significant period of time, if at all. The risks inherent in
     international operations include:

          o    management of geographically dispersed operations;

          o    a longer sales cycle, especially in areas of recent expansion;

          o    longer accounts receivable payment cycles, and greater difficulty
               in the collection of past due accounts;

          o    difficulty in establishing relationships with government-owned or
               subsidized communications providers;

          o    general economic conditions in each country;

          o    currency controls and exchange rate fluctuations;

          o    seasonal reductions in business activity specific to certain
               markets;

                                 Page 20 of 26


          o    loss of revenues, property and equipment from expropriation,
               nationalization, war, insurrection, terrorism and other political
               risks;

          o    foreign taxes and the overlap of different tax structures,
               including modifications to the U.S. tax code as a result of
               international trade regulations;

          o    greater difficulty in safeguarding intellectual property;

          o    import and export licensing requirements and other trade
               restrictions;

          o    involuntary renegotiation of contracts with foreign governments
               and communications carriers; and

          o    existence or adoption of laws and regulations affecting the pace
               of deregulation, taxation of our business and the general
               business climate for foreign companies.

     Continued international expansion of our business will require further
     significant management attention and financial resources. In order to
     further expand internationally, we may be required to establish
     relationships with additional distributors and third-party integrators. We
     cannot assure you that we will effectively establish such relationships. If
     international revenues are not adequate to offset the additional expenses
     of expanding international operations, it could harm our business,
     financial condition and results of operations.

     To date, a very high percentage of international sales have been
     denominated in U.S. dollars, and accordingly we have not been significantly
     exposed to fluctuations in non-U.S. currency exchange rates. As a result,
     our revenues in international markets may be harmed by a strengthening U.S.
     dollar. However, we expect that in future periods a greater portion of
     international sales may be denominated in currencies other than U.S.
     dollars, thereby exposing us to exchange rate gains and losses on non-U.S.
     currency transactions. We may choose to limit such exposure by entering
     into various hedging strategies. We cannot be certain that any hedging
     strategies that we undertake would be successful in avoiding
     exchange-related losses.

     WE MAY BE UNABLE TO PRODUCE SUFFICIENT QUANTITIES OF OUR PRODUCTS BECAUSE
     WE OBTAIN KEY COMPONENTS FROM SOLE AND LIMITED SOURCE SUPPLIERS. IF WE ARE
     UNABLE TO OBTAIN THESE COMPONENTS, WE COULD BE UNABLE TO SHIP OUR PRODUCTS
     IN A TIMELY MANNER.

     Currently, our products utilize certain semiconductors that are available
     from only one manufacturer and other components that are available from
     only one or a limited number of suppliers. While alternative suppliers have
     been identified for a variety of key components, those alternative sources
     have not been qualified by us. Our qualification process could be lengthy,
     and we cannot assure you that additional sources would become available to
     us on a timely basis, or if such sources were to become available, that the
     components would be comparable in price and quality to our current
     components. We have no long-term agreements with our suppliers and, in the
     case of many components, make our purchases with purchase orders on an
     "as-needed basis." Certain components require an order lead-time of
     approximately nine months. Other components that currently are readily
     available may become difficult to obtain in the future. Our failure to
     order sufficient quantities of these components in advance of product
     delivery deadlines could prevent us from adequately responding to
     unanticipated increases in customer orders. In the past, we have
     experienced delays in the receipt of a variety of our key components, which
     have resulted in delays in product deliveries. We could experience delays
     or reductions in product shipments or increases in product costs if we are
     unable to obtain sufficient key components as required or to develop
     alternative sources if and as required in the future.

                                 Page 21 of 26


     OUR INVENTORY MAY BECOME OBSOLETE OR UNUSABLE.

     We make advance purchases of certain components in relatively large
     quantities to ensure that we have an adequate and readily available supply.
     Our failure to accurately project our needs for these components and the
     demand for our products that incorporate them, or changes in our business
     strategy that reduce our need for these components could result in these
     components becoming obsolete prior to their intended use or otherwise
     unusable in our business. For example, during the three months ended June
     30, 2001, we wrote-off approximately $300,000 of assets related to the VIA
     softswitch product following our decision to refocus our strategy and
     streamline operations to reduce our cost structure in response to the
     generally weakened economic environment and changing demand characteristics
     in some of our markets.

     WE RELY ON THIRD-PARTY SUBCONTRACTORS TO MANUFACTURE AND DEVELOP OUR
     PRODUCTS. OUR ABILITY TO SELL PRODUCTS TO OUR CUSTOMERS COULD BE IMPAIRED
     IF THESE SUBCONTRACTORS DO NOT MEET THEIR COMMITMENTS TO US.

     We rely exclusively upon third-party subcontractors to manufacture our
     subassemblies, and we have retained, from time to time, third-party design
     services in the development of application-specific integrated circuits or
     the layout of circuit boards. We also frequently subcontract the
     development of specific features and enhancements of our products. Our
     reliance on third-party subcontractors involves a number of risks,
     including the potential absence of adequate capacity, the unavailability of
     or interruption in access to certain process technologies, and reduced
     control over product quality, delivery schedules, manufacturing yields and
     costs. Any disruption in our relationships with third-party subcontractors
     and our inability to develop alternative sources if and as required in the
     future could result in delays or reductions in product shipments or
     increases in product costs.

     WE RELY UPON SOFTWARE LICENSED FROM THIRD PARTIES. IF WE ARE UNABLE TO
     MAINTAIN THESE SOFTWARE LICENSES ON COMMERCIALLY REASONABLE TERMS, OUR
     BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS COULD BE HARMED.

     We rely upon software that we license from third parties, including
     software that is integrated with our internally developed software and used
     in our products to perform key functions. The inability to maintain any
     software licenses on commercially reasonable terms could result in shipment
     delays or reductions until equivalent software could be developed or
     licensed and integrated into our products, which could harm our business,
     financial condition and results of operations.

     WE MAY NOT RECEIVE THE INTENDED BENEFITS OF FUTURE ACQUISITIONS, JOINT
     VENTURES OR OTHER BUSINESS RELATIONSHIPS.

     We may in the future pursue acquisitions of businesses, products and
     technologies, or the establishment of joint venture, strategic partnership
     or other arrangements that could expand our business. The negotiation of
     potential acquisitions or strategic relationships, as well as the
     integration of an acquired or jointly developed business, technology or
     product, could cause diversion of management's time and resources. Future
     acquisitions and strategic relationships by us could result in potentially
     dilutive issuances of equity securities, the incurrence of debt and
     contingent liabilities, amortization of intangibles, research and
     development write-offs and other acquisition-related expenses. We cannot
     assure you that any acquisition or joint venture will be successfully
     integrated with our operations. If we were to pursue any such acquisition
     or strategic relationship, we may not receive the intended benefits of the
     acquisition or strategic relationship. Also, we may pursue arrangements
     with third parties to perform specified activities for us such as the
     development of products or product features. We cannot assure you that
     these arrangements will produce to the level of quality or in the time
     frame expected, which could materially harm our business.

                                 Page 22 of 26


     WE MAY RELY ON STRATEGIC DISTRIBUTION AND MARKETING RELATIONSHIPS WITH
     MANUFACTURERS OF COMPLIMENTARY PRODUCTS. IF WE FAIL TO DERIVE BENEFITS FROM
     OUR FUTURE STRATEGIC RELATIONSHIPS, OUR BUSINESS MAY SUFFER.

     We may in the future develop distribution and marketing relationships with
     other companies as part of our business strategy. If we cannot successfully
     enter and maintain these types of relationships on favorable terms, our
     business may suffer.

     There are various risks associated with our reliance on these
     relationships, including:

          o    the number of different companies that we may be able to support
               will be limited by the finite amount of our resources available
               to support the varying levels of customized engineering required
               to achieve and maintain interoperability and feature/function
               performance;

          o    these companies may not develop or deliver their products on a
               timely basis, or may not develop products that perform as
               expected or are priced competitively;

          o    these companies may subsequently change the design of their
               products in a manner that requires substantial additional
               development by us to keep our products compatible;

          o    these companies may develop a fully-integrated solution that
               alleviates the need for non-integrated products, including our
               products; and

          o    some of our current and potential strategic partners are either
               actual or potential competitors, which may impair the viability
               of these relationships.

     Many of these risks are outside of our control. Any of these risks could
     materially harm our business, financial condition and results of
     operations.

     WE MAY BE ACCUSED OF INFRINGING THE PROPRIETARY RIGHTS OF OTHERS, WHICH
     COULD SUBJECT US TO COSTLY AND TIME-CONSUMING LITIGATION.

     The communications industry is characterized by the existence of a large
     number of patents and frequent allegations of patent infringement. We have
     received, and may receive in the future, notices from holders of patents
     that raise issues as to possible infringement by our products. As the
     number of competitive products increases and the functionality of these
     products further overlaps, we believe that we may become increasingly
     subject to allegations of infringement. To date, we have engaged in
     correspondence with two third-party holders of patents as a result of such
     notices. While we believe that our products do not infringe on any valid
     patents cited in the notices, questions of infringement and the validity of
     patents in the field of communications signaling technologies involve
     highly technical and subjective analyses. We cannot assure you that any of
     these patent holders, or others, will not initiate legal proceedings in the
     future against us, or that if any proceedings were initiated, we would be
     successful in defending ourselves. Any proceeding could be time consuming
     and expensive to defend or resolve, result in substantial diversion of
     management resources, cause product shipment delays, or force us to enter
     into royalty or license agreements rather than dispute the merits of any
     such proceeding initiated against us. We cannot assure you that any such
     royalty or license agreements would be available on terms acceptable to us,
     if at all.

     OUR LIMITED ABILITY OR FAILURE TO PROTECT OUR INTELLECTUAL PROPERTY MAY
     MATERIALLY HARM OUR ABILITY TO COMPETE.

     Our continued success is dependent in part upon our proprietary technology.
     To protect our proprietary technology, we rely on a combination of
     technical innovation, trade secret, copyright and trademark laws,
     non-disclosure agreements and, to a lesser extent, patents, each of which
     affords only limited protection. In addition, the laws of some foreign
     countries do not protect our proprietary rights in the products to the

                                 Page 23 of 26


     same extent as do the laws of the U.S. Despite the measures taken by us, it
     may be possible for a third party to copy or otherwise obtain and use our
     proprietary technology and information without authorization. Policing
     unauthorized use of our products is difficult, and litigation may be
     necessary in the future to enforce our intellectual property rights. Any
     litigation could be time consuming and expensive to prosecute or resolve,
     result in substantial diversion of management resources, and materially
     harm our business, financial condition and results of operations. We cannot
     assure you that we will be successful in protecting our proprietary
     technology or that our proprietary rights will provide us a meaningful
     competitive advantage.

     WE MAY FACE POTENTIAL LIABILITY FOR PRODUCT DEFECTS.

     Products as complex as ours may contain undetected defects or errors when
     first introduced or as enhancements are released that, despite our testing,
     are not discovered until after a product has been installed and used by
     customers, which could result in delayed market acceptance of the product
     or damage to our reputation and business. To date, we have not been
     materially harmed by products containing defects or errors. We attempt to
     include provisions in our agreements with customers that are intended to
     limit our exposure to potential liability for damages arising out of
     defects or errors in our products. However, the nature and extent of these
     limitations vary from customer to customer and it is possible that these
     limitations may not be effective as a result of unfavorable judicial
     decisions or laws enacted in the future. Although we have not experienced
     any product liability suits to date, the sale and support of our products
     entail the risk of these claims. Any product liability claim brought
     against us, regardless of its merit, could result in material expense to
     us, diversion of management time and attention, and damage to our business
     reputation and our ability to retain existing customers or attract new
     customers.

     OUR THREE FOUNDERS OWN APPROXIMATELY 78% OF OUR COMMON STOCK, WHICH ALLOWS
     THEM TO CONTROL THE MANAGEMENT AND AFFAIRS OF OUR COMPANY OR PREVENT A
     CHANGE OF CONTROL.

     As of June 30, 2001, our three founders, Samuel S. Simonian, Elie S.
     Akilian and Mark A. Weinzierl, beneficially owned approximately 78% of the
     outstanding shares of our common stock. Consequently, two or more of these
     individuals, acting together, could control the outcome of all matters
     submitted for stockholder action, including the election of our board of
     directors and the approval of significant corporate transactions. They
     effectively control the management and affairs of our company, which could
     have the effect of delaying or preventing a change in control of our
     company. In addition, Messrs. Simonian, Akilian and Weinzierl are each
     members of our board of directors and have significant influence in
     directing the actions taken by our board.

     OUR BUSINESS AND REPUTATION COULD SUFFER IF WE DO NOT PREVENT SECURITY
     BREACHES.

     We have included security features in some of our products that are
     intended to protect the privacy and integrity of customer data. Despite the
     existence of these security features, our products may be vulnerable to
     breaches in security due to unknown defects in the security mechanisms, as
     well as vulnerabilities inherent in the operating system or hardware
     platform on which the product runs and/or the networks linked to that
     platform. Security vulnerabilities, regardless of origin, could jeopardize
     the security of information stored in and transmitted through the computer
     systems of our customers. Any security problem may require significant
     capital expenditures to solve and could materially harm our reputation and
     product acceptance.

     WE HAVE ADOPTED ANTI-TAKEOVER DEFENSES THAT COULD DELAY OR PREVENT AN
     ACQUISITION OF OUR COMPANY.

     Our certificate of incorporation and bylaws and Delaware law contain
     provisions that may have the effect of discouraging, delaying or preventing
     a change in control of our company or unsolicited acquisition proposals
     that a stockholder may consider favorable. For example, we have a
     classified board of directors with three-year terms, our stockholders are
     unable to take action by written consent and our stockholders are limited
     in their ability to make proposals at stockholder meetings.

                                 Page 24 of 26


     VOLATILITY IN OUR STOCK PRICE COULD RESULT IN CLAIMS AGAINST US.

     The market price of our common stock has been, and is likely to continue to
     be, highly volatile and may be significantly affected by factors such as:

          o    variations in our results of operations;

          o    changes in our business strategy;

          o    future sales of common stock;

          o    the announcement of technological innovations or new products by
               us, our competitors and others;

          o    market analysts' estimates of our performance;

          o    general market and economic conditions; and

          o    equity market conditions and industry-specific equity market
               trends.

     The public markets have experienced significant volatility that has
     particularly affected the market prices of securities of many technology
     and telecommunications companies for reasons that have often been unrelated
     to financial results. This volatility has and may continue to materially
     harm the market price of our common stock as well as our visibility and
     credibility in our markets.

     Additionally, in the past, securities class action litigation often has
     been brought against a company following periods of volatility in the
     market price of its common stock. We may be the target of similar
     litigation in the future. Securities litigation could result in substantial
     costs and divert our management's attention and resources.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     We are exposed to immaterial levels of market risk. Revenues from customers
     located outside of the U.S. represented 62.0% of total revenues for the six
     months ended June 30, 2001, 55.8% of total revenues in 2000, 51.7% of total
     revenues in 1999 and 52.2% of total revenues in 1998. To date, a very high
     percentage of international revenues have been denominated in U.S. dollars,
     and accordingly, we have not been significantly exposed to fluctuations in
     currency exchange rates.

     Our international business is subject to the typical risks of any
     international business, including, but not limited to, the risks described
     in Item 2 - "Management's Discussion and Analysis of Financial Condition
     and Results of Operations - Risk Factors". Accordingly, our future results
     could be materially harmed by changes in these or other factors.

     Currently, our cash is solely invested in money market funds denominated in
     U.S. dollars. We account for these investments in accordance with SFAS No.
     115, ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES.
     These cash equivalents are treated as available-for-sale under SFAS No.
     115. The carrying value of these cash equivalents approximates fair market
     value.

PART II. OTHER INFORMATION

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

     The Securities and Exchange Commission on May 26, 1999 declared effective
     the Registration Statement on Form S-1 (File No. 333-59753) relating to the
     initial public offering of our common stock. As of June 30, 2001, we have
     used all of the net offering proceeds for the purchase of temporary
     investments, consisting of cash, cash equivalents, and short-term
     investments. We currently intend to use the net proceeds of the offering
     for working capital and general corporate purposes, including financing
     accounts receivable and capital expenditures made in the ordinary course of
     business. We also may apply a portion of the proceeds of the offering to
     acquire businesses, products and technologies, or enter into joint venture
     arrangements, that are complementary to our business and product offerings;
     however, at this time we have not identified a specific acquisition or
     joint venture or allocated a specific amount for this purpose.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     Meeting of Stockholders, or until their successors have been elected and
     qualified.
