                               PROSPECTUS SUMMARY

     This summary highlights selected information contained elsewhere in this
prospectus. You should read the following summary together with the more
detailed information in this prospectus, including risk factors, regarding our
company and the common stock sold in this offering.

                               NET.GENESIS CORP.

     We provide software and professional services that help our customers
understand, analyze and improve their online businesses. Our net.Analysis
software enables companies to collect, store, organize and analyze detailed
information about the online behavior of customers and other visitors on their
web sites. Through net.Analysis, our customers can also import and analyze
information about these e-customers that is available from other online and
offline software systems and databases. Our professional services organization
provides strategic analytic consulting and product integration and installation
services. This combined software and services solution enables companies to:

     - better tailor and target their marketing initiatives

     - restructure their web sites to facilitate electronic commerce, or
       e-commerce

     - provide more relevant and cost-effective content

     - improve web site design

     - better allocate advertising and partnership resources

     - better plan their investments in web site hardware and software

     As use of the Internet has grown, companies have invested in a variety of
software applications and services to develop and support their web sites and
improve the online experience of their e-customers. In the face of increasing
competition, online businesses are seeking to improve their ability to attract,
serve and retain customers and more effectively communicate and conduct
e-commerce with them. To achieve these objectives, companies must understand the
needs and web site behavior of their e-customers. Companies must also understand
the costs and benefits of each of their web initiatives, such as online
marketing campaigns, e-commerce efforts, web site content, advertising and other
promotional sponsorships, and their investments in web site hardware and
software. Complicating matters, companies often desire to understand the
behavior of their e-customers in the context of their traditional offline
businesses.

     Our net.Analysis software helps companies achieve these objectives by
collecting information about the online behavior of e-customers on their web
sites, such as the web pages they viewed most often, the banner advertisements
they clicked on, how they navigated through the site, how they purchased
products and services, and why they may have abandoned the site. With
net.Analysis' reporting capabilities, companies can select the data they wish to
analyze, segment that data according to criteria they establish, and use it to
analyze the online behavior of selected categories of e-customers.

     net.Analysis enables companies to organize this information, which we call
e-customer intelligence, in ways that help them understand and improve their
online businesses. For example, a company can use our software to identify the
characteristics of its best e-customers and to analyze trends in their online
activity. This can help the company evaluate the cost-effectiveness of its
e-commerce efforts, promotional campaigns or investments in content. With
net.Analysis, a company can also import customer information from its other
online and offline software systems and databases and correlate this information
with information about customers' online behavior to learn, for example, whether
e-customers buy from the company's offline retail establishments or respond to
the company's direct mail or other offline marketing initiatives. This ability
to form a

                                       3

<PAGE>   8

unified view of e-customer behavior in the context of the company's entire
business is a valuable asset for many companies.

     We have designed net.Analysis to perform reliably in complex web site
environments and to manage tens of millions to over 100 million hits per day. We
have also designed net.Analysis to be compatible with Microsoft Windows NT and
Unix, two widely used operating systems, and third-party software applications
and to simplify the development of add-on analytic applications.

     Our professional services organization has extensive experience using
net.Analysis to analyze and understand e-customer behavior, and uses this
expertise to help companies develop web-based performance measurements that are
relevant to their online businesses. We also help companies design web site
modifications and develop customized analyses and reports to meet their online
business goals.


     We have licensed net.Analysis to over 200 customers. In 1999, some of our
largest customers included Barnes & Noble, Bell Atlantic, Charles Schwab, Delta
Airlines, EarthWeb, Egreetings Network, Fidelity Investments, The Gap, General
Electric, Intraware, NextPlanetOver Online, Travelscape.com and Universal
Studios, none of which accounted for more than 10% of our total revenues in
1999. We target Fortune 1000 companies as well as new businesses using the
Internet as their primary business channel. We sell our products through our
direct sales force and to a lesser extent indirectly through arrangements with
systems integrators, original equipment manufacturers and other technology
providers.


     Our executive offices are located at 150 CambridgePark Drive, Cambridge,
Massachusetts 02140, and our telephone number at that location is (617)
665-9200. Our web site is located at www.netgen.com. Information contained on

                                  RISK FACTORS

     You should carefully consider the following risk factors and all other
information contained in this prospectus before purchasing our common stock.
Investing in our common stock involves a high degree of risk. Any of the
following risks could harm our business, results of operations and financial
condition and could result in a complete loss of your investment.

RISKS RELATED TO OUR BUSINESS

  OUR LIMITED OPERATING HISTORY MAKES IT DIFFICULT TO PREDICT OUR FUTURE
  OPERATIONS

     Although we were formed in 1994, our current business operations have a
limited history. We introduced the first version of our net.Analysis software in
January 1996 and recorded our first revenue from this product and related
services in February 1996. To date, we have generated only limited amounts of
revenue from the sale of net.Analysis and related products and services.
Accordingly, you have limited information about our company with which to
evaluate our business and prospects. Before buying our common stock, you should
consider the risks and difficulties frequently encountered by early stage
companies in new and rapidly evolving markets, particularly those companies
whose businesses depend on the Internet.

  WE HAVE A HISTORY OF LOSSES, EXPECT TO INCUR SUBSTANTIAL LOSSES AND NEGATIVE
  OPERATING CASH FLOWS AND MAY NOT ACHIEVE OR MAINTAIN PROFITABILITY IN THE
  FUTURE

     We have not achieved profitability since 1994. We expect to continue to
incur substantial losses for the foreseeable future and may never become
profitable. We incurred net losses of $3.1 million in 1997, $5.8 million in 1998
and $16.0 million in 1999. As a result of ongoing operating losses, we had an
accumulated deficit of $30.8 million at December 31, 1999. As we grow our
business, we expect operating expenses and capital expenditures to increase
significantly, and we expect to continue to incur losses and negative cash flow
from operations. As a result, we will need to generate significant revenue to
achieve and maintain profitability. We do not believe that we can sustain the
percentage rates at which our revenue has grown in recent quarters. We may not
be able to sustain or increase profitability or cash flows from operations on a
quarterly or annual basis in the future. Our failure to achieve or maintain
profitability may materially and adversely affect the market price of our common
stock.

  WE EXPECT OUR REVENUE AND RESULTS OF OPERATIONS TO FLUCTUATE. THE MARKET PRICE
  OF OUR COMMON STOCK WOULD LIKELY FALL IF OUR QUARTERLY RESULTS ARE LOWER THAN
  THE EXPECTATIONS OF SECURITY ANALYSTS OR STOCKHOLDERS

     We have experienced substantial fluctuations in both our annual and
quarterly revenue and results of operations, and we expect those fluctuations to
continue for the foreseeable future. We believe the following factors are those
most likely to cause our revenue and results of operations to fluctuate:

     - uncertain demand for our products and services

     - unanticipated changes in the market for e-customer intelligence software

     - the timing of sales and delivery of our products and services

     - the timing of customer implementations of our products

     - the mix of revenue derived from our products and services

     - timing of introductions of new products and services by us or our
       competitors

     - seasonal trends in our customers' business activity

     - timing of hiring of personnel and changes in productivity of our
       professional services personnel and direct sales personnel

                                       7

<PAGE>   12

If our revenue or results of operations fall below the expectations of
securities analysts or investors, the market price of our common stock would
likely fall, and you could lose some or all of your investment. We budget our
expenses in part according to the revenue we forecast. A significant percentage
of our expenses, particularly salaries and rent, are relatively fixed. In
addition, commissions for our sales personnel are generally based on the orders
we book rather than the revenue we recognize in the quarter and could therefore
increase in an amount disproportionate to the increase in revenue. As a result,
if our revenue falls below our expectations, we may be unable to curtail our
expenses quickly enough to avoid losses greater than expected. As a result, our
results of operations may be volatile and difficult to predict. We do not
believe that period-to-period comparisons of our revenue and operating results
are necessarily meaningful. You should not rely on the results of one quarter as
an indication of future performance.

  MOST OF OUR REVENUE EACH QUARTER IS DERIVED FROM A SMALL NUMBER OF LARGE
  ORDERS. IF WE FAIL TO COMPLETE ONE OR MORE LARGE ORDERS IN ANY QUARTER, OUR
  REVENUE COULD BE SIGNIFICANTLY LOWER THAN EXPECTED


     We derive a significant portion of our revenue in each quarter from a small
number of large orders. Our quarterly operating results would be adversely
affected if we were unable to complete one or more large orders in any quarter.
For example, during 1998 Bell Atlantic and E*Trade each accounted for more than
10% of our total revenue.


  OUR SALES CYCLES ARE LONG AND UNPREDICTABLE, MAKING IT DIFFICULT TO FORECAST
  OUR REVENUES AND BUDGET OUR EXPENSES

     Our sales cycles are long and unpredictable because we generally need to
educate potential customers about the benefits of e-customer intelligence
software. In addition, we believe that, for many of our potential customers, the
purchase of our software and services can represent a significant portion of
their web site budget and a substantial commitment of personnel resources. As a
result, we experience widely varying sales cycles that typically range from two
to six months. Our long and varying sales cycles make it difficult to predict
the quarter in which particular sales may occur and, therefore, to forecast our
revenue and budget our expenses. Moreover, we believe that, as our business
develops, a significant portion of our sales will increasingly fall within the
last month of a quarter, making it difficult to predict revenue until late in
the quarter and to adjust expenses accordingly.

  ALL OF OUR REVENUE IS DERIVED FROM OUR NET.ANALYSIS SOFTWARE AND RELATED
  PRODUCTS AND SERVICES, AND ANY DECLINE IN DEMAND FOR THAT PRODUCT OR RELATED
  PRODUCTS AND SERVICES WOULD SERIOUSLY HARM OUR BUSINESS


     Since 1996, our net.Analysis software and related products and services
have accounted for all of our revenue. We anticipate that sales of our
net.Analysis software and related products and services will continue to account
for substantially all of our revenue for the foreseeable future. Consequently,
any decline in the demand for our net.Analysis software, or its failure to
achieve and maintain market acceptance, would seriously harm our business.



  WE FACE INTENSE COMPETITION, AND IF WE ARE UNABLE TO COMPETE SUCCESSFULLY, WE
  COULD EXPERIENCE REDUCED DEMAND FOR OUR PRODUCTS AND SERVICES, PRICE
  REDUCTIONS AND REDUCED GROSS MARGINS FOR OUR PRODUCTS AND SERVICES, ANY OF
  WHICH WOULD SERIOUSLY HARM OUR BUSINESS



     Even though the market for e-customer intelligence software and other web
site analysis software is immature, it is already intensely competitive,
fragmented, evolving and subject to rapid technological change. We expect
competition to intensify in the future. Increased competition could result in
reduced demand for our products and services, price reductions and reduced gross
margins for our products and services, any of which could seriously harm our
business. For a discussion of our primary competitors, see
"Business -- Competition."

                                        8
<PAGE>   13


     We may not be able to compete successfully against current and future
competitors. Many of our competitors have longer operating histories and
significantly greater financial, technical, marketing and other resources than
we do. They have significantly greater name recognition and a larger installed
base of customers than we have. In addition, many of our competitors have well-
established relationships with our current and potential customers and have
extensive knowledge of our target markets. As a result, our competitors may be
able to respond more quickly to evolving industry standards and changes in
customer requirements, or to devote greater resources to the development,
promotion and sale of their products than we can. In the past, we have lost
potential customers to competitors for various reasons and may continue to do
so.



  INCREASED COOPERATION AND CONSOLIDATION AMONG OUR COMPETITORS COULD ENABLE
  THEM TO OFFER MORE COMPETITIVE PRODUCTS, WHICH COULD LEAD TO REDUCED SALES OF
  NET.ANALYSIS AND RELATED SERVICES



     Current and potential competitors have established or may establish
cooperative relationships among themselves or with third parties to increase the
ability of their products to address customer needs. In addition, companies
marketing Internet applications that are currently complementary to our products
could incorporate into their products enhanced analytic and reporting
capabilities that could adversely affect demand for our software and services.
We also expect that industry consolidation will increase competition. For
example, Vignette, a company with which we have a strategic technology
relationship, offers software that enables businesses to better manage their
online relationships by personalizing their web sites. Vignette recently
announced its agreement to acquire DataSage, a company that offers software that
collects real-time information on online customer interactions. With the
acquisition, Vignette will augment its ability to provide real-time reporting
and analysis of customer behavior. These additional capabilities may make its
products more competitive with net.Analysis. Similarly, Accrue recently acquired
Marketwave and NeoVista Software, and as a result can offer a wider selection of
products to its customers. Accordingly, it is possible that alliances among our
competitors, new competitors or companies that result from combinations among
our competitors, may emerge and rapidly acquire significant market share.



  OUR ABILITY TO INCREASE REVENUE DEPENDS ON EXPANDING OUR DIRECT SALES FORCE,
  WHICH MAY BE DIFFICULT BECAUSE OF THE SHORTAGE OF QUALIFIED SALES PERSONNEL
  AND BECAUSE IT TAKES TIME FOR NEW HIRES TO BECOME PRODUCTIVE


     If we are unable to significantly expand our direct sales force, we may not
increase our market share or revenue, which could seriously harm our business.
To date, we have derived the substantial majority of our revenue from the
efforts of our direct sales force. We believe we must increase the size of our
direct sales force in order to increase revenue. Competition for qualified sales
personnel is intense, and we may not be able to hire a sufficient number of
sales people with the skills we need. Moreover, the technical nature of our
products lengthens the time it takes for our new sales people to become
productive, typically three to six months. This lag in productivity may make it
more difficult to meet our sales growth targets. Further, we may not generate
sufficient sales to offset the increased expense resulting from growing our
sales force, and we may be unable to manage a larger sales force.

  IF WE ARE UNABLE TO EXPAND OUR INDIRECT SALES THROUGH INTERNET-ORIENTED
  SYSTEMS INTEGRATORS, RESELLERS, ORIGINAL EQUIPMENT MANUFACTURERS AND
  APPLICATION SERVICE PROVIDERS, WE MAY NOT MAINTAIN OR INCREASE OUR MARKET
  SHARE OR REVENUE, WHICH COULD SERIOUSLY HARM OUR BUSINESS

     Our strategy includes developing relationships with a variety of
Internet-oriented systems integrators, resellers, original equipment
manufacturers and application service providers in the United States and abroad
to augment the efforts of our direct sales force. These third parties may not
succeed in marketing or selling our products and services. We have little or no
control over the activities of these third parties, and poor performance by any
of them could injure our reputation, create liabilities for us and seriously
harm our business. These third parties may also market and

                                        9
<PAGE>   14

sell competing products and services, which could adversely affect sales of our
products and services. We may be unable to effectively manage potential
conflicts among these third parties. Our reliance on these third parties may
also increase our credit risk because we effectively bear the risk of
non-payment by both the third parties and their customers. Any failure by these
parties to pay for our products and services in a timely manner could reduce our
cash flows and harm our financial condition.

  OUR FAILURE TO UPGRADE OUR PRODUCTS AND INTRODUCE NEW PRODUCTS TO MEET MARKET
  REQUIREMENTS, SUCH AS DEMAND FOR THE ABILITY OF OUR SOFTWARE TO HANDLE
  INCREASING TRAFFIC ON WEBSITES, WOULD SERIOUSLY AFFECT OUR REVENUES AND HARM
  OUR BUSINESS

     If we are unable to upgrade our current products and introduce new products
and services to meet technological innovations or demands of online businesses,
we could lose current and potential customers, which would adversely affect our
revenue and harm our business. The market for our products experiences rapid
technological change, frequent new product introductions, Internet-related
technology enhancements, uncertain product life cycles, and changes in customer
requirements and preferences. The rapid growth of the Internet and intense
competition in our industry exacerbate these market characteristics. For
example, if we do not continue to upgrade our products to handle the increasing
traffic on our customers' web sites, demand for our software could diminish.
Similarly, widespread adoption of technology that enables web site visitors to
conceal their web site activities could seriously impair the capabilities and
usefulness of our products. Moreover, in developing our products, we make
assumptions regarding the industry standards and technologies that our customers
and competitors will adopt. If we choose to support standards or technologies
that the industry does not adopt, market acceptance of our products may be
significantly reduced or delayed. Upgrading or developing our technology poses
complex technical challenges and requires substantial expenditures and lead
times. We have experienced delays in releasing new and enhanced products and may
experience similar delays in the future. Any delays in developing and releasing
our new or enhanced products, or decisions by potential customers to defer
purchases in anticipation of new products or releases by us or our competitors,
could seriously harm our business.

  IF WE FAIL TO CONTINUE TO GENERATE REVENUE FROM OUR CURRENT CUSTOMERS, OUR
  BUSINESS WILL BE SERIOUSLY HARMED

     Our failure to continue to sell products and services to our existing
customers could seriously harm our business. In 1999, we derived approximately
50% of our total revenue from sales of products and services to customers that
had made purchases from us before 1999. We expect to continue to derive a
significant portion of our revenue from our existing customers. Our ability to
retain our customers will depend on a variety of factors, including the analytic
capabilities, scalability, compatibility, reliability and cost-effectiveness of
our products and services as well as our ability to effectively market our
products and services. If we fail to generate repeat and expanded business from
our current customers, our operating results would be seriously harmed.

  THE EXPANSION OF OUR BUSINESS HAS PLACED, AND CONTINUES TO PLACE, A
  SIGNIFICANT STRAIN ON OUR MANAGEMENT, OPERATING SYSTEMS AND RESOURCES AND
  COULD SERIOUSLY HARM US

     Our failure to properly manage the expansion of our business could
seriously harm us. Our business has recently experienced a period of significant
and rapid expansion that has placed, and continues to place, a significant
strain on our management, operating systems and resources. For example, Brian
Zanghi, our Executive Vice President and Chief Operating Officer, joined us in
January 2000, and several other members of our management team joined us in
1999. During 1999, the number of our employees grew from 64 to 150, and we plan
to continue to expand our business by hiring additional personnel. To the extent
that our business continues to grow rapidly, we must implement and improve our
operating systems, including our administrative, financial, customer

                                       10
<PAGE>   15

service and operational systems, procedures and controls. We are currently
implementing new software systems for enterprise resource planning and human
resources management, including payroll and benefits. We could be seriously
harmed if our current and anticipated personnel, systems, procedures and
controls are inadequate to support our future operations, or if we are unable to
complete the necessary improvements to our systems, procedures and controls on a
timely basis.

  IF WE LOSE THE SERVICES OF OUR CHIEF EXECUTIVE OFFICER, CHIEF FINANCIAL
  OFFICER OR OTHER MEMBERS OF OUR SENIOR MANAGEMENT TEAM, OUR BUSINESS COULD
  SUFFER

     Our future success depends on the continued service of our senior
management and other key personnel. In particular, we rely on the continued
services of Lawrence S. Bohn, our President and Chief Executive Officer, John
Delea, our Chief Financial Officer and Vice President of Finance and
Administration, Eric Richard, a founder and our Chief Technology Officer, and
Matthew Cutler, a founder and our Chief E-Business Intelligence Officer. The
loss of the services of one or more of these individuals or any other key
personnel could result in reduced sales, delays in new product development,
decreased customer satisfaction, a reduction of management resources and other
injury to our ability to achieve our business objectives. None of our key
personnel is bound by a long-term employment agreement with us, and we do not
intend to maintain any life insurance to compensate us for the loss of any of
our key personnel.

  BECAUSE THERE IS INTENSE COMPETITION FOR QUALIFIED PERSONNEL IN OUR INDUSTRY,
  WE MAY NOT BE ABLE TO RECRUIT OR RETAIN THE PERSONNEL WE NEED, WHICH COULD
  ADVERSELY AFFECT OUR ABILITY TO ACHIEVE OUR BUSINESS OBJECTIVES

     Our ability to achieve our business objectives could be adversely affected
if we cannot identify, attract, hire, train, retain and motivate a substantial
number of additional personnel. In particular, we are seeking to hire highly
skilled systems engineers and other technical and engineering personnel and
employees for our professional services organization. Because of the technical
nature of our products, it typically takes several months to train our
professional service personnel to provide services effectively. If we are unable
to expand and train our professional services staff, we could be unable to meet
customer demand for our services, which could cause customer dissatisfaction and
lost sales. Our headquarters are located in the metropolitan Boston,
Massachusetts area, and competition for qualified personnel in this area, as
well as the other areas where we need personnel, is intense. Competition is
particularly strong for qualified systems engineers and other software
development and technical personnel. Many other employers are able to offer
significantly more attractive compensation and benefits than we do. We may be
unable to recruit and retain the personnel we need. Our business would be
seriously harmed if we are unable to retain our existing employees or to hire
the other highly qualified personnel we need.

  IF WE FAIL TO SUCCESSFULLY PROMOTE OUR CORPORATE AND PRODUCT BRAND NAMES, OR
  IF WE INCUR SIGNIFICANT EXPENSES PROMOTING AND MAINTAINING OUR BRANDS, OUR
  BUSINESS COULD BE HARMED

     As competition in the market for our products increases, we believe the
importance of brand name recognition will increase. We have limited name
recognition, and our failure to achieve and maintain widespread recognition of
our corporate and product brand names may limit our sales opportunities, which
could limit our market share and seriously harm our long-term business
prospects. Successfully promoting and positioning our corporate and product
brands will depend largely on the effectiveness of our marketing efforts and our
ability to develop reliable and useful products at competitive prices. We may
find it necessary to accelerate expenditures on our sales and marketing efforts
or otherwise increase our budget for creating and maintaining brand awareness
among potential customers. If we fail to successfully promote and maintain our
brand or incur significant expenses in promoting our brand, our business,
results of operations and financial condition could be materially and adversely
affected.

                                       11
<PAGE>   16

  IF WE ARE UNABLE TO OBTAIN ADDITIONAL CAPITAL AS NEEDED IN THE FUTURE, OUR
  BUSINESS MAY BE ADVERSELY AFFECTED AND THE MARKET PRICE FOR OUR COMMON STOCK
  COULD BE SIGNIFICANTLY REDUCED

     We currently anticipate that our available cash resources and the net
proceeds from this offering will be sufficient to meet our anticipated working
capital and capital expenditure requirements for at least the next 12 months. We
may need to raise additional debt or equity capital, however, to fund more rapid
expansion of our operations and promotion of our corporate and brand names, to
enhance our products and services, or to make acquisitions. We have raised
capital through the issuance of debt or equity securities three times since June
1998. If we raise additional funds through further issuances of equity or
convertible debt securities, our existing stockholders could suffer significant
dilution, and any new equity securities we issue could have rights, preferences
and privileges superior to those of holders of our common stock, including
shares of common stock sold in this offering. In addition, we may not be able to
obtain additional financing on terms favorable to us, if at all. If adequate
funds are not available on terms favorable to us, our business, results of
operations and financial condition could be materially and adversely affected.

  WE MAY NEED TO ACQUIRE COMPLEMENTARY PRODUCTS, SERVICES, BUSINESSES OR
  TECHNOLOGIES TO REMAIN COMPETITIVE. ACQUISITIONS MAY BE UNAVAILABLE TO US OR
  MAY EXPOSE US TO RISKS THAT COULD NEGATIVELY AFFECT OUR OPERATING RESULTS

     We believe our customers will increasingly demand additional product
capabilities, features and services. Our internal resources may be inadequate to
meet those demands on a timely basis. As a result, we may need to acquire
products, services, businesses, technologies or other capabilities in order to
remain competitive. Our failure to meet customer demands could seriously harm
our business. We may be unable to successfully identify or acquire on
commercially reasonable terms the products, services, businesses, technologies
or capabilities that we need. Many of our competitors have greater financial
resources and more well-established industry relationships than we do, and may
therefore compete more effectively for acquisition opportunities. If we make an
acquisition, we may be exposed to additional risks that could seriously harm our
business, including the following:

     - acquired products, businesses, services, technologies and capabilities
       may not meet customer needs or may not achieve or sustain widespread
       market acceptance

     - we may encounter difficulties in assimilating acquired products,
       services, businesses, technologies and capabilities

     - we may encounter difficulties in integrating acquired personnel and
       operations

     - acquired products, services, businesses, technologies and capabilities
       may result in decreased revenue from our existing products and services

     Acquisitions could disrupt our ongoing business, distract our employees,
increase our expenses and adversely affect our results of operations. We could
issue equity securities to pay for an acquisition, which could dilute the equity
interests of our existing stockholders. In addition, acquisitions may involve
investment-related or other charges and amortization of acquired technology,
goodwill and other intangible assets, which may adversely affect our results of
operations.

  FUTURE EXPANSION OF OUR INTERNATIONAL OPERATIONS WILL REQUIRE SIGNIFICANT
  MANAGEMENT ATTENTION AND FINANCIAL RESOURCES AND OUR EFFORTS TO EXPAND
  INTERNATIONALLY MAY NOT SUCCEED

     We intend to expand our international operations and international sales
and marketing efforts, particularly in Europe and Asia. We have limited
experience in developing localized versions of our software products and in
marketing, selling and distributing our software and services internationally.
To date, our only offices outside the United States are located in London,
England. To
                                       12
<PAGE>   17

successfully expand international sales, we must expand our international
operations, recruit additional international sales and support personnel, and
expand our international distribution channels. This international expansion
strategy will require significant management attention and financial resources,
and we may not be successful in implementing our strategy. In particular,
because we rely on international resellers, our success in international markets
will depend to a significant degree on the success of those resellers and their
willingness to dedicate resources to the sale of our products and services.
International sales are subject to other inherent risks, such as:

     - compliance with multiple, conflicting and changing governmental laws and
       regulations

     - the existence of protectionist laws and business practices that favor
       local competition

     - longer sales and collection cycles, including difficulties obtaining and
       enforcing judgments against delinquent customers

     - foreign currency exchange rate fluctuations

     - difficulties in managing and staffing distant foreign operations

     - reduced protection for intellectual property rights in some countries

     - import and export licensing requirements

     - impact of recessions in economies outside the United States

     - seasonal reductions in business activity

     - political and economic instability

Our failure to manage these risks adequately could seriously harm our business.

  OUR BUSINESS AND PROSPECTS WOULD SUFFER IF WE ARE UNABLE TO PROTECT OUR
  INTELLECTUAL PROPERTY RIGHTS


     Our success depends in large part on our intellectual property,
particularly our software. If we fail to successfully enforce our intellectual
property rights, other companies might copy our technology or introduce products
or services that compete with ours. This could reduce our revenues and weaken
our competitive position. We rely solely on a combination of copyright,
trademark and trade secrets law, assignment of invention and confidentiality
agreements, confidentiality procedures and licensing arrangements to establish
and protect our intellectual property rights. We have no patents. We have filed
a provisional patent application relating to our net.Activator technology. We
have registered the trademarks net.Genesis and net.Analysis in the United States
and claim trademark rights in CartSmarts, Design for Analysis, DFA,
net.Dashboard, net.Instrument, net.Stream and ReportSite. Our efforts to protect
our intellectual property may be inadequate. Existing trade secret, copyright
and trademark laws offer only limited protection, and we may be unsuccessful in
obtaining that protection, or our efforts to obtain that protection may be
opposed by others. For example, we have been advised that our application to
register the mark net.Genesis in the European Union has been opposed by a large
Spanish insurance company that owns a number of marks incorporating the word
"Genesis." In addition, the laws of some foreign countries where we market our
products and services do not protect intellectual property rights to the same
extent as do the laws of the United States. We may be required to spend
significant resources to monitor infringement of and enforce our intellectual
property rights.


     Third parties could copy or otherwise obtain and use our products or
technology without our authorization. They could also independently develop
similar technology that may infringe our intellectual property rights. We may
not be able to detect infringement and may lose our competitive position in the
market before we do so. Competitors may also design around our technology or
develop competing technologies. If this occurs, our business and prospects would
be materially and adversely affected.

                                       13
<PAGE>   18

  OTHERS MAY BRING INFRINGEMENT CLAIMS AGAINST US WHICH COULD HARM OUR BUSINESS,
  RESULTS OF OPERATIONS AND FINANCIAL CONDITION

     Reliance on intellectual property rights is pervasive in our industry, and
we expect that as competition intensifies, companies will continue to pursue
vigorous enforcement of their intellectual property rights through litigation
and other means. As a result, third parties may claim that our products or
services infringe their intellectual property rights. Any such claim could
seriously harm our business, results of operations and financial condition. We
have not performed a comprehensive analysis of patents that may limit our
ability to do business. An increasing number of companies are seeking and
obtaining patents regarding methods of doing business on the Internet, and valid
patents that apply to our methods of doing business may have been issued or may
be issued in the future. Defending any claim of intellectual property
infringement, regardless of merit, is expensive and time-consuming and may
distract our management's attention away from our business. As a result of any
claim or anticipated claim, we may agree or be forced to:

     - pay substantial damages

     - cease selling or using products and services that incorporate the
       infringed intellectual property

     - obtain a license for the infringed intellectual property, which might not
       be available on commercially reasonable terms or which could adversely
       affect our results of operations and financial condition

     - attempt to modify our products and services to avoid infringing others'
       intellectual property rights, which we might be unable to do at all or
       quickly enough to prevent serious harm to our competitive position in the
       market

  YEAR 2000 PROBLEMS COULD HAVE AN ADVERSE EFFECT ON OUR OPERATIONS

     We are subject to potential Year 2000 problems affecting our internal
systems, the systems of our suppliers and our customers. If any of these were
not corrected for Year 2000 problems, our operations could be materially
impacted. We conducted a review and examination of these systems and a summary
of our results is included elsewhere in this prospectus.

  IF OUR SOFTWARE PRODUCES INACCURATE INFORMATION ABOUT THE ONLINE CUSTOMER
  BEHAVIOR AND TRANSACTIONS WE TRACK OR DISRUPTS THE FUNCTIONING OF OTHER
  APPLICATIONS, WE MAY EXPERIENCE CUSTOMER DISSATISFACTION, LOSS OF CUSTOMERS,
  OR BOTH, AND BE EXPOSED TO LAWSUITS

     The failure of our products to provide accurate information concerning web
site visitor behavior could result in adverse publicity, loss of or delay in
market acceptance and claims by customers against us, any of which could
seriously harm our business, results of operations and financial condition.
Software often contains defects, particularly when first introduced or updated,
which can adversely affect performance or result in inaccurate data. We may not
discover software defects that adversely affect our products until after they
are deployed. Moreover, our products typically become incorporated in our
customers' web site hardware and software systems, which vary greatly in
composition and complexity. As a result, we cannot anticipate and plan for the
configuration of every customer's system, and our products may not work properly
in every installation or may disrupt the proper functioning of other
applications within that system. Accordingly, customers may discover errors or
flaws in our products. Our license agreements typically contain provisions that
attempt to limit our liability, but these provisions may not be enforceable in
all circumstances. In some circumstances, we may be liable for damages caused by
those errors, which could seriously harm our business. We carry only limited
amounts of product liability insurance, which may be insufficient to protect us
from any losses we suffer.

RISKS RELATED TO OUR INDUSTRY

  IF THE INTERNET FAILS TO GROW AS A MEDIUM FOR COMMUNICATION AND ELECTRONIC
  COMMERCE, OUR FUTURE REVENUE AND BUSINESS PROSPECTS WOULD BE MATERIALLY AND
  ADVERSELY AFFECTED

     Our future revenue and business prospects depend in part on a significant
increase in the use of the Internet as a medium for communication and electronic
commerce. The Internet is still emerging as a channel for selling goods and
services to consumers and businesses. Further, Internet advertising and
marketing is new and rapidly evolving, and it cannot yet be compared with
traditional advertising media or marketing programs to gauge its effectiveness.
Our business and prospects will be materially and adversely affected if the
Internet does not become accepted as a medium for purchasing goods and services
online or for advertising and marketing.

  WE PARTICIPATE IN THE UNPROVEN MARKET FOR E-CUSTOMER INTELLIGENCE SOFTWARE,
  WHICH MAKES THE DEMAND FOR OUR PRODUCTS UNCERTAIN

     The market for e-customer intelligence products and services is in an early
stage of development and may not continue to grow. Accordingly, the demand for
our products is uncertain. Many companies in our target markets are unaware that
e-customer intelligence software such as ours is available or beneficial and may
choose to allocate their resources elsewhere, including to internally developed
e-customer intelligence capabilities. Moreover, many companies may continue to
rely on traditional offline customer intelligence methods. In order for us to be
successful, our potential customers must recognize the value of and decide to
invest in e-customer intelligence software, and, in particular, adopt our
product. Any failure of this market to continue to develop would seriously harm
our business.

  WE DEPEND ON THE CONTINUED VIABILITY OF THE INTERNET INFRASTRUCTURE

     Our business depends upon the development and maintenance of a viable
Internet infrastructure. The current Internet infrastructure may be unable to
support an increased number of users, greater frequency of use or increases in
user demand for faster access. The timely development of products such as
high-speed modems and communications equipment will be necessary to continue
reliable Internet access. In addition, the Internet has experienced outages and
delays as a result of damage to portions of its infrastructure. Outages and
delays could adversely affect our customers' web sites and third-party web
applications and the willingness of our current and potential customers to use
our e-customer intelligence software. Even if the necessary infrastructure or
technologies are developed, we may have to spend considerable resources to adapt
our offerings accordingly. In addition, the effectiveness of the Internet may
decline due to delays in the development or adoption of new standards and
protocols designed to support increased levels of activity. If new standards or
protocols are developed, we may be required to incur substantial expenditures to
adapt our products. Any of these events could seriously harm our business.

  THE CAPABILITIES OF OUR PRODUCTS COULD BE LIMITED BY THE PRIVACY CONCERNS OF
  ONLINE COMMERCE PARTICIPANTS AND GOVERNMENT REGULATORY REQUIREMENTS, WHICH
  COULD SERIOUSLY HARM OUR BUSINESS

     Web sites typically capture information about the preferences and
demographics of online users each time a user visits the web site or volunteers
information in response to survey or other questions. Our net.Analysis software
enables organizations to analyze and use this customer information for their
business purposes, including marketing campaigns and customer solicitations.
Privacy concerns may cause web site visitors to resist providing personal data,
to avoid web sites known to collect data on visitor behavior and to take other
steps to prevent the involuntary collection of personal data, all of which would
impair the effectiveness of our products and could seriously harm our business.
Moreover, even the perception of privacy concerns may indirectly

                                       15
<PAGE>   20

inhibit market acceptance of our products or services. If customer privacy
concerns are not adequately addressed, our business could be seriously harmed.

     In addition, federal, state, local or foreign governments or agencies have
adopted and may in the future adopt legislative or regulatory requirements
designed to protect individual privacy on the Internet. For example, the United
States' Children's Online Privacy Act, which took effect in October 1999,
imposes new obligations on all online businesses that target children under the
age of 13 and other requirements on all businesses engaged in online commerce to
protect the privacy of children under the age of 13. In addition, the European
Union has adopted a directive addressing data privacy that may result in
limitations on the collection and use of specific personal information regarding
Internet users. Developments like these may significantly impair the growth or
evolution of the Internet and online commerce. As a result, the demand for
products like net.Analysis may not grow as anticipated. This could seriously
harm our business.

  IF GOVERNMENT REGULATIONS AND LEGAL UNCERTAINTIES RELATED TO DOING BUSINESS ON
  THE INTERNET CAUSE A DECLINE IN E-COMMERCE AND INTERNET ADVERTISING AND
  MARKETING, OUR BUSINESS AND PROSPECTS COULD BE MATERIALLY AND ADVERSELY
  AFFECTED

     Laws and regulations directly applicable to Internet communications,
commerce and marketing are becoming more prevalent. If any of these laws hinders
the growth in use of the Internet generally or decreases the acceptance of the
Internet as a medium for communication, commerce and marketing, our business and
prospects may suffer materially. The United States Congress has enacted Internet
laws regarding children's privacy, copyrights and taxation. Other laws and
regulations may be adopted covering issues such as user privacy, pricing,
content, taxation and quality of products and services. State and foreign
governments might attempt to regulate Internet transmissions or levy sales or
other taxes relating to Internet activity. It may take years to determine
whether and how existing laws such as those governing intellectual property,
privacy, libel and taxation apply to the Internet and Internet advertising and
marketing services. In addition, the growth and development of the market for
Internet commerce may prompt calls for more stringent consumer protection laws,
both in the United States and abroad, that may impose additional burdens on
companies conducting business over the Internet.

  INCREASED LIMITATION OR ABOLITION OF THE USE OF COOKIES COULD LIMIT OUR
  ABILITY TO COLLECT DATA, IMPAIR THE EFFECTIVENESS OF OUR SOFTWARE AND REQUIRE
  PRODUCT MODIFICATIONS, ANY OF WHICH COULD SERIOUSLY HARM OUR BUSINESS

     The passage of laws limiting or abolishing the use of cookies could
seriously harm our business. A cookie is information created by a web server
that is stored on an end-user's computer, often without the user's knowledge,
that can be used to track and record the user's online behavior and profile.
Cookies generally may be removed or disabled by the user. Our products capture
some data with cookies to identify unique user information and preferences. Some
countries have imposed laws limiting the use of cookies, and a number of
commentators, advocates and governmental bodies in the United States and other
countries have urged passage of laws limiting or abolishing the use of cookies.
If these laws were passed, we would have to disable certain data collection
features of our products, which would reduce their usefulness to our customers,
and we might be unable to develop alternative methods to gather data currently
obtained with cookies. Even if we could develop those methods, the development
could involve significant expenses and might not occur in time to prevent damage
to our competitive position.

RISKS RELATED TO THIS OFFERING AND OWNERSHIP OF OUR COMMON STOCK

  FOLLOWING THE OFFERING, TRADING IN OUR COMMON STOCK MAY BE LIMITED AND YOU
  MUST BE ABLE TO WITHSTAND A POSSIBLE LOSS OF YOUR INVESTMENT

     This is our initial public offering. A public market for trading our common
stock has not existed before this offering. Although this offering will result
in a public trading market for our common stock, we do not know how liquid the
market for our stock will be. The price of the common stock being sold in this
offering will be determined through negotiations between the underwriters and
us. If you purchase common stock in this offering, you may not be able to resell
such stock at or above the price you paid.

  THE MARKET PRICE OF OUR COMMON STOCK MAY BE VOLATILE, WHICH COULD RESULT IN
  SUBSTANTIAL LOSSES FOR INVESTORS PURCHASING SHARES IN THIS OFFERING

     The market price of our common stock after this offering may vary from its
initial public offering price. Fluctuations in market price and volume are
particularly common among securities of Internet and other technology companies.
As a result, you may be unable to sell your shares of common stock at or above
the initial offering price. The market price of our common stock may fluctuate
significantly in response to the following factors, some of which are beyond our
control:

     - general fluctuations in stock market prices and volume, which are
       particularly common among highly volatile securities of software and
       Internet-related companies like ours

     - variations in our quarterly operating results

     - changes in securities analysts' estimates of our financial performance

     - changes in market valuations of similar companies

     - announcements by us or our competitors of significant products,
       contracts, acquisitions or strategic partnerships

     - additions or departures of key personnel

  WE COULD BE THE SUBJECT OF SECURITIES CLASS ACTION LITIGATION DUE TO FUTURE
  STOCK PRICE VOLATILITY

     The stock market in general, and market prices for the securities of
Internet-related companies like ours in particular, recently have experienced
extreme volatility that often has been unrelated to the operating performance of
the underlying companies. These broad market and industry fluctuations may
adversely affect the market price of our common stock, regardless of our
operating performance. Recently, when the market price of a stock has decreased
rapidly, holders of that stock have often instituted securities class action
litigation against the company that issued the stock. If any of our stockholders
brought a lawsuit against us, our defense of the lawsuit could be costly and
divert the time and attention of our management.

  SUBSTANTIAL SALES OF OUR COMMON STOCK COULD CAUSE OUR STOCK PRICE TO DECLINE

     Sales of a substantial number of shares of common stock after this
offering, or the perception that sales could occur, could adversely affect the
market price of the common stock. On completion of this offering, we will have
20,459,832 shares of common stock outstanding and 2,270,484 shares subject to
outstanding options and warrants. In general, the 4,250,000 shares sold in this
offering will be freely tradable without restriction or further registration
under the federal securities laws. The remaining 16,209,832 shares of common
stock outstanding on completion of the offering will be "restricted securities"
as that term is defined in Rule 144. Our directors, executive officers and most
other stockholders have executed lock-up agreements that limit their ability to
sell common stock. These stockholders have agreed not to sell or otherwise
dispose of any shares of common stock for a period of 180 days after the date of
this prospectus without the prior written approval of Chase

                                       17
<PAGE>   22

Securities Inc., which could be given at any time. When the lock-up agreements
expire or are terminated, most of the restricted securities will become eligible
for sale.

  MANAGEMENT COULD APPLY THE PROCEEDS OF THIS OFFERING TO USES THAT DO NOT
  INCREASE OUR MARKET VALUE OR IMPROVE OUR OPERATING RESULTS

     We will use our net proceeds from this offering for general corporate
purposes and working capital. We have not reserved or allocated the net proceeds
for any specific purpose, and we cannot state with certainty how our management
will use the net proceeds. Accordingly, our management will have considerable
discretion in applying the net proceeds. We may use the net proceeds for
purposes that do not result in any increase in our results of operations or
market value.

  OUR DIRECTORS AND MANAGEMENT WILL COLLECTIVELY CONTROL OVER 40% OF OUR
  OUTSTANDING COMMON STOCK

     Immediately after this offering, our directors and executive officers and
their affiliates will collectively control approximately 40% of our outstanding
common stock. As a result, these stockholders, if they act together, will be
able to influence our management and affairs and all matters requiring
stockholder approval, including the election of directors and approval of
significant corporate transactions. This concentration of ownership may have the
effect of delaying or preventing a change in control of our company and might
adversely affect the market price of our common stock.

  ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW COULD
  PREVENT OR DELAY A CHANGE IN CONTROL OF OUR COMPANY

     Provisions of our certificate of incorporation and by-laws may discourage,
delay or prevent a merger, acquisition or change of control that a stockholder
may consider favorable. These provisions could also discourage proxy contests
and make it more difficult for stockholders to elect directors and take other
corporate actions. The existence of these provisions could limit the price that
investors might be willing to pay in the future for shares of our common stock.
These provisions include:

     - authorizing the issuance of "blank check" preferred stock

     - providing for a classified board of directors with staggered, three-year
       terms

     - providing that directors may only be removed for cause by a two-thirds
       vote of stockholders

     - limiting the persons who may call special meetings of stockholders

     - prohibiting stockholder action by written consent

     - establishing advance notice requirements for nominations for election to
       the board of directors and for proposing matters to be submitted to a
       stockholder vote

     Delaware law may also discourage, delay or prevent someone from acquiring
or merging with our company or obtaining control of our company.

  INVESTORS IN THIS OFFERING WILL PAY A MUCH HIGHER PRICE THAN THE BOOK VALUE OF
  OUR COMMON STOCK

     The initial public offering price per share of our common stock is $9.25
higher than the pro forma net tangible book value per share of our common stock,
based on an assumed public offering price of $12.00 per share. As a result,
investors purchasing common stock in this offering will incur immediate and
substantial dilution. In the past, we issued options and warrants to acquire
common stock at prices significantly below the assumed initial public offering
price per share. To the extent

                                       18
<PAGE>   23

these outstanding options and warrants are later exercised, there will be
further dilution to investors.

  THE FORWARD-LOOKING STATEMENTS WE MAKE IN THIS PROSPECTUS MIGHT PROVE
  INACCURATE. AS A RESULT, OUR ACTUAL RESULTS, LEVELS OF ACTIVITY, PERFORMANCE
  OR ACHIEVEMENTS MAY DIFFER MATERIALLY FROM THOSE EXPRESSED IN THE
  FORWARD-LOOKING STATEMENTS

     Some of the statements we make in this prospectus are forward-looking
statements. In some cases, you can identify forward-looking statements by
terminology such as "may," "will," "should," "could," "expects," "plans,"
"intends," "anticipates," "believes," "estimates," "predicts," "potential" or
"continue" or similar terminology. These statements involve known and unknown
risks and uncertainties that may cause our actual results, levels of activity,
performance or achievements to differ materially from any future results, levels
of activity, performance or achievements expressed or implied by such
forward-looking statements. These factors include, among other things, those
listed under "Risk Factors" and elsewhere in this prospectus. We cannot
guarantee any future results, levels of activity, performance or achievements.
Moreover, neither we nor anyone else assumes responsibility for the accuracy and
completeness of these statements. We undertake no obligation to update any of
the forward-looking statements after the date of this prospectus.

     This prospectus includes forward-looking statements about market data
relating to the Internet and to us. These statements are based on estimates
contained in studies published by International Data Corporation, a market
research firm. International Data Corporation arrived at those estimates by
using methodologies and assumptions chosen by it. For example, International
Data Corporation's estimate of growth in Internet commerce revenue, appearing
below in "Business -- Industry Background," is based on extrapolation by
International Data Corporation from historical data collected by them from
surveys and interviews, including data about:

     - the installed base for personal computers and other Internet access
       devices

     - the number of users per device

     - the amount of time spent on the web

     - the value of user purchases on the web

     - the number of sites on the web

     If the methodologies and assumptions, such as those described above, that
International Data Corporation used to make these estimates prove to be
incorrect, actual results could differ from the estimates. There can be no
assurance that the market for Internet commerce will grow at the rate projected
by International Data Corporation. Failure of this market to grow at the
estimated rate could seriously harm our business and could cause the price of
our common stock to decline.

<PAGE>   24

                                USE OF PROCEEDS

     We estimate that the net proceeds from our sale of the 4,250,000 shares of
common stock we are offering will be approximately $46.4 million, based on an
assumed initial public offering price of $12.00 per share, after deducting
estimated underwriting discounts and commissions and estimated offering expenses
that we will pay. Our estimated net proceeds will be approximately $53.5 million
if the underwriters fully exercise their over-allotment option.


     The principal purposes of this offering are to obtain additional capital,
to create a public market for our common stock and to facilitate future access
to public equity markets. As of the date of this prospectus, we have not
allocated the net proceeds of this offering for specific uses. We intend to use
our net proceeds for working capital and general corporate purposes. The actual
amounts expended for specific purposes will vary significantly depending on a
number of factors, including cash generated from operations, if any, changes in
the competitive landscape, demands of customers, and the extent and timing of
our entry into target markets. We may also use a portion of the net proceeds for
acquisitions of businesses, products and technologies that complement our
business. Although we have evaluated possible acquisitions from time to time, we
currently have no commitments or agreements to make any acquisitions, and we
cannot assure you that we will make any acquisitions in the future. Pending
those uses, we intend to invest the net proceeds in U.S. government securities
and other short-term, investment-grade, interest-bearing instruments or high-
grade corporate notes.


                                DIVIDEND POLICY

     We have never declared or paid any cash dividends on shares of our capital
stock. We currently intend to retain any earnings to fund the development and
growth of our business and do not anticipate paying cash dividends in the
foreseeable future. Our payment of any future dividends will be at the
discretion of our board of directors after taking into account our financial
condition, operating results, cash needs and growth plans. Our agreement with
our lender contains restrictive covenants that generally prohibit us from paying
cash dividends, making any distribution on any class of stock or making stock
repurchases.

                                 CAPITALIZATION

     The following table summarizes our capitalization as of December 31, 1999:


     - on an actual basis, reflecting a charter amendment filed on February 2,
       2000 to effect a three-for-four reverse split of our common stock


     - on a pro forma as adjusted basis to reflect:

        - the conversion of all of our outstanding preferred stock into common
          stock upon completion of this offering

        - the issuance of 85,843 shares of common stock upon exercise of a
          warrant, which we expect will occur before the completion of this
          offering

        - a charter amendment, to be effective upon completion of this offering,
          that will authorize a class of undesignated preferred stock

        - our sale of 4,250,000 shares of common stock at an assumed initial
          public offering price of $12.00 per share, after deducting estimated
          underwriting discounts and commissions and estimated offering expenses
          that we will pay

     You should read this table together with our financial statements and
related notes appearing elsewhere in this prospectus.

     The information in the foregoing table excludes:

          December 31, 1999, which have a weighted average exercise price of
          $1.49 per share

        - 2,850,000 additional shares reserved as of December 31, 1999 for

                                    DILUTION

     Our pro forma net tangible book value as of December 31, 1999 was
approximately $9.4 million, or $0.59 per share of common stock. Pro forma net
tangible book value per share is determined by dividing the amount of our total
tangible assets less our total liabilities by the pro forma number of shares of
common stock outstanding, after giving effect to the conversion of our
outstanding preferred stock and the exercise of a warrant, which we expect will
occur before the completion of this offering. After giving effect to our sale of
4,250,000 shares of common stock at an assumed initial public offering price of
$12.00 per share and after deducting estimated underwriting discounts and
commissions and estimated offering expenses that we will pay, our adjusted pro
forma net tangible book value as of December 31, 1999 would have been $55.9
million, or $2.75 per share. This amount represents an immediate increase in pro
forma net tangible book value to our existing stockholders of $2.16 per share
and an immediate dilution to new investors of $9.25 per share. The following
table illustrates this per share dilution:

     If the underwriters exercise their option to purchase additional shares in
this offering in full, our adjusted pro forma net tangible book value at
December 31, 1999 would have been $63.0 million, or $3.00 per share,
representing an immediate increase in pro forma net tangible book value to our
existing stockholders of $2.41 per share and an immediate dilution to new
investors of $9.00 per share.

     The following table summarizes as of December 31, 1999, on a pro forma
basis after giving effect to the conversion of our outstanding preferred stock
and the exercise of a warrant as described above, the number of shares of common
stock purchased from us, the total consideration paid to us and the average
price per share paid by our existing stockholders and by new investors, based
upon an assumed initial public offering price of $12.00 per share before
deducting the estimated underwriting discounts and commissions and estimated
offering expenses payable by us.

     The preceding discussion and tables assume no exercise of any stock options
or warrants outstanding as of December 31, 1999, except as stated above. As of
December 31, 1999, there were outstanding options to purchase a total of
1,696,597 shares of common stock at a weighted average exercise price of $1.49
per share and warrants, other than that described above, to purchase a total of
209,804 shares of common stock at an exercise price of $2.45 per share. To the
extent any of these options or warrants are exercised, there will be further
dilution to new investors.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     You should read the following discussion and analysis of our financial
condition and results of operations together with "Selected Financial Data" and
our financial statements and related notes appearing elsewhere in this
prospectus. This discussion and analysis contains forward-looking statements
that involve risks, uncertainties and assumptions. Our actual results may differ
materially from those anticipated in these forward-looking statements as a
result of many factors, including those set forth under "Risk Factors" and
elsewhere in this prospectus.

OVERVIEW

     We offer e-customer intelligence software that enables companies to
understand and improve their online businesses. We license net.Analysis to
customers for a fee and also provide related maintenance and support services.
In addition, we provide professional consulting services. These services include
analytic consulting, product implementation, application integration,
customization of e-customer analysis reporting and training.

     From our inception in May 1994 through December 31, 1995, our operations
consisted primarily of start-up activities, including raising capital,
recruiting personnel, conducting research and development for net.Analysis and
several other Internet software product and service offerings that we have since
discontinued, establishing the market for our initial products and purchasing
operating assets. Since 1995, we have invested in research and development for
net.Analysis, building sales channels, expanding marketing activities and
developing administrative operations. In January 1996, we began actively
marketing our net.Analysis product. To date, we have developed and released four
major versions of net.Analysis. We currently have over 200 customers. We market
and sell our products primarily through our direct sales force.

     Since 1996, our net.Analysis software and related products and services
have accounted for all of our revenue. We anticipate that licensing of
net.Analysis and related products and services will continue to account for
substantially all of our revenue for the foreseeable future. Consequently, a
decline in the price of or demand for our net.Analysis software, or its failure
to achieve or maintain market acceptance, would seriously harm our business,
financial condition and results of operations.

     We license net.Analysis and our other software products to our customers
primarily on a perpetual, non-exclusive and non-transferable basis. Our pricing
model is based on the number of the customer's managed servers, the platform
supported and the number of end users of our software, allowing for additional
revenue as a customer's requirements grow. Support and maintenance contracts,
which are purchased with initial product licenses and are renewable annually
thereafter, entitle customers to telephone, e-mail and web-based support and to
routine product upgrades, when and if available. The price for our support and
maintenance services is based on a percentage of the then-current list price of
the software. Consulting fees for implementation services and training are
charged either on a time-and-materials basis or on a fixed-fee basis in the case
of packaged services, such as our FastPath implementation package.

     We recognize revenues in accordance with Statement of Position 97-2,
"Software Revenue Recognition," which we adopted in 1998. Fees from licenses are
recognized as revenue when a contract has been executed and the product has been
delivered, provided fees are fixed or determinable, collection is probable and
there are no uncertainties with respect to customer acceptance. If uncertainties
exist, we defer revenue until the customer accepts the product or service.
Revenue under arrangements where multiple products or services are sold together
under one contract is allocated to each element based on their relative fair
values, with these fair values being determined using the price charged when
that element is sold separately. License fees from software sold together with
services are generally recognized upon delivery of the software, provided that
the above criteria have been met and the services are not essential to the
functionality of the software. In instances where these criteria have not been
met, both the license
                                       25
<PAGE>   30

and professional services fees are recognized under the percentage-of-completion
method of contract accounting, based upon the proportion of hours expended to
total estimated hours at completion. Losses, if any, on fixed-price contracts
are recognized when the loss is determined.

     Service revenue consists of fees from professional services and from
software maintenance and support. Professional services include analytic
consulting, product implementation, application integration, report
customization, training and support. We recognize professional services fees as
we perform the services.

     Customers typically purchase maintenance and support agreements annually.
We recognize revenue from maintenance and support agreements ratably over the
term of the agreement, typically one year. We record cash receipts from clients
and billed amounts due from clients in excess of revenue recognized as deferred
revenue. The timing and amount of cash receipts from clients can vary
significantly depending on specific contract terms and can therefore have a
significant impact on the amount of deferred revenue in any given period.

     Since our inception, we have incurred substantial costs to develop our
technology and products, to recruit and train personnel for our engineering,
sales and marketing and professional services departments, and to establish our
administrative organization. As a result, we have incurred net losses in each
fiscal quarter since December 31, 1994 and, as of December 31, 1999, had an
accumulated deficit of $30.8 million. We anticipate that our operating expenses
will increase substantially in future quarters as we increase sales and
marketing operations, develop new distribution channels, fund greater levels of
research and development, broaden professional consulting services and support,
and improve operational and financial systems. We expect that these operating
expenses, as well as anticipated capital expenditures, will constitute a
material use of our cash resources. We expect to incur additional losses and
continued negative cash flow from operations. We may not achieve or sustain
profitability or positive cash flow from operations.

     We have recorded deferred stock-based compensation related to grants of
stock options. This amount represents the difference between the exercise price
of these stock option grants and the amount subsequently determined to be the
fair market value of the underlying common stock for financial reporting
purposes at the time of grant. Of this amount, we amortized approximately
$388,000 in 1999. We will amortize $5.7 million of stock-based compensation,
plus the additional amounts recorded in connection with stock options granted
after December 31, 1999, ratably over the remaining vesting periods of the
options, generally four years or less, which will affect our reported results of
operations through 2003. All of these amounts appear on our statements of
operations as stock-based compensation.

  Comparison of 1998 and 1999

     Total Revenue.  Total revenue increased by $4.9 million, or 317%, to $6.5
million for 1999 from $1.6 million for 1998. No customer accounted for 10% or
more of our total revenue in 1999.

     Product Revenue.  Product revenue increased by $2.9 million, or 304%, to
$3.8 million for 1999 from $937,000 for 1998. Substantially all of the growth in
product revenue was due to an increase of approximately 300% in the average
dollar size of licenses, attributable to larger implementations and price
increases. Product revenue as a percentage of total revenue decreased to 58% for
1999 from 60% for 1998. We anticipate that revenue from licenses of net.Analysis
will continue to represent a majority of our revenues in the future. We expect
that because of our small historical revenue base, the recent percentage growth
rates of our product revenue will not be sustainable in the future.

     Service Revenue.  Service revenue increased by $2.1 million, or 335%, to
$2.7 million for 1999 from $631,000 for 1998. Approximately $1.6 million of the
increase in the dollar amount of service revenue was attributable to increased
implementation and consulting services in connection with increased product
license sales. The balance of the increase was attributable to greater sales of
maintenance contracts associated with higher dollar value sales of net.Analysis
licenses. We expect that the recent percentage growth rates of our service
revenue will not be sustainable in the future.

     Cost of Product Revenue.  Cost of product revenue consists primarily of
royalties associated with third-party software embedded in our software products
and software product costs, such as user manuals, packaging and media costs.
Cost of product revenue decreased by $12,000, or 5%, to $220,000 for 1999 from
$232,000 for 1998. The decrease was attributable to a decrease in license fees

                                       27
<PAGE>   32

for third-party software purchased for resale by us as part of our net.Analysis
product. Cost of product revenue as a percentage of product revenue declined to
6% for 1999 from 25% for 1998. This decrease was attributable to the
above-mentioned decrease in license fees for third-party software.

     Cost of Service Revenue.  Cost of service revenue consists primarily of
salaries, benefits and associated overhead costs of our professional services
organization. Cost of service revenue increased by $2.4 million, or 310%, to
$3.1 million for 1999 from $761,000 for 1998. Substantially all of the increase
was attributable to an increased number of personnel in our professional
services organization. This growth has required that we invest in hiring and
training personnel and building a management and operational infrastructure.
This investment has resulted in the cost of service revenue exceeding our
service revenue. Cost of service revenue as a percentage of service revenue
decreased to 113% for 1999 from 121% for 1998. We expect that in dollar amount
our cost of service revenue will continue to exceed our service revenue for at
least the next several quarters.


     Sales and Marketing Expenses.  Sales and marketing expenses consist
primarily of personnel costs, including related overhead costs and commissions,
as well as travel and entertainment expenses, trade show and other promotional
expenses, advertising, and other marketing costs. Sales and marketing expenses
increased by $7.5 million, or 244%, to $10.5 million for 1999 from $3.0 million
for 1998. Approximately $4.1 million of the increase was due to increased
personnel in our sales and marketing departments. Approximately $1.7 million of
the increase was due to increased commissions earned by sales personnel on
higher dollar sales. The balance of the increase was attributable to increased
marketing communications expenditures associated with product introductions and
efforts to create increased awareness of our products and services. Sales and
marketing expenses as a percentage of total revenue declined to 160% for 1999
from 194% for 1998. We expect that sales and marketing expenses will continue to
increase in dollar amount to support marketing programs for new product
launches, promotion of awareness of our corporate and brand names, international
expansion and increased sales efforts. Sales and marketing expenses for the
three months ending March 31, 2000 will also include a charge of approximately
$143,000, excluding stock-based compensation of $351,000, which amounts are
attributable to a separation agreement entered into in January 2000 with our
former Vice President, Worldwide Sales and Service. See
"Management -- Separation Agreement."


     Research and Development Expenses.  Research and development expenses
consist primarily of salaries, benefits and related overhead costs attributable
to our research and development organization, as well as the cost of
consultants. Research and development expenses increased by $2.4 million, or
108%, to $4.7 million for 1999 from $2.3 million for 1998. Approximately $1.9
million of the increase was attributable to increased staffing and associated
support for software engineers required to expand and enhance our product
offerings. The balance of the increase was attributable to increased consulting
costs related to the development and enhancement of our products. Research and
development expenditures are charged to operations as incurred. Research and
development expenses as a percentage of total revenue declined to 72% for 1999
from 145% for 1998. We believe that research and development expenses will
continue to increase in dollar amount as we add additional research and
development personnel.

     General and Administrative Expenses.  General and administrative expenses
consist primarily of salaries, benefits and overhead costs associated with our
executive, finance, human resource, legal, accounting and internal information
system functions. General and administrative expenses increased by $2.4 million,
or 204%, to $3.5 million for 1999 from $1.1 million for 1998. Approximately
$900,000 of the increase was the result of increased staffing and associated
expenses necessary to manage and support our growth. Approximately $700,000 of
the increase was attributable to increased professional service fees. General
and administrative expenses as a percentage of total revenue declined to 53% for
1999 from 73% for 1998. We expect that general and administrative expenses will
continue to increase in dollar amount as we expand our operations and
infrastructure to support our planned future growth and transition to operating
as a public company.
                                       28

     Stock-based Compensation.  We incurred stock-based compensation expense of
$531,000 for 1999. The expense includes $143,000 related to extension of options
in connection with employee severance. It also includes $388,000 for
amortization of the deferred expense attributable to the issuance during 1999 of
stock options with exercise prices less than the amount subsequently determined
to be the fair market value of the underlying stock for financial reporting
purposes on the date of grant. These options generally vest over four years or
less. The remaining deferred compensation expense of approximately $5.7 million
will be amortized ratably over the remaining vesting periods of the options, and
will affect periods ending after December 31, 1999. We also expect to record a
charge for stock-based compensation of approximately $351,000 during the three
months ending March 31, 2000 in connection with the separation agreement entered
into in January 2000 with our former Vice President, Worldwide Sales and
Service.


     Other Income (Loss).  Other income (loss) consists of interest income,
interest expense, other income, loss on disposal of fixed assets and other
expenses. Other income decreased by $108,000 from $111,000 in 1998 to $3,000 for
1999 due to higher interest expense incurred on larger average outstanding
borrowings during 1999.

  Comparison of 1997 and 1998

     Total Revenue.  Total revenue increased by $559,000, or 55%, to $1.6
million for 1998 from $1.0 million for 1997. Two customers, E*Trade and Bell
Atlantic, each accounted for more than 10% of our total revenue in 1998.

     Product Revenue.  Product revenue increased by $92,000, or 11%, to $937,000
for 1998 from $845,000 for 1997. Substantially all of the increase in product
revenue was due to increased average dollar size of licenses. Product revenue as
a percentage of total revenue declined to 60% for 1998 from 84% for 1997.

     Service Revenue.  Service revenue increased by $468,000, or 286%, to
$631,000 for 1998 from $164,000 for 1997. Service revenue as a percentage of
total revenue increased to 40% for 1998 from 16% for 1997. Approximately
$360,000 of this growth was due to expanded implementation and consulting
service offerings. The balance of the increase was due to greater sales of
maintenance contracts associated with higher dollar sales of net.Analysis
licenses.

     Cost of Product Revenue.  Cost of product revenue increased by $141,000, or
155%, to $232,000 for 1998 from $91,000 for 1997. Approximately $110,000 of the
increase was attributable to increased license fees for third-party software
purchased for resale by us as part of our net.Analysis product. The balance of
the increase was attributable to increases in unit volume. Cost of product
revenue as a percentage of product revenue increased to 25% for 1998 from 11%
for 1997, primarily as a result of an increase in the cost of licenses of
third-party software that we resell as part of our solution.

     Cost of Service Revenue.  Cost of service revenue increased by $212,000, or
39%, to $761,000 for 1998 from $549,000 for 1997. Approximately $320,000 of the
increase was a result of an increase in the number of our professional services
personnel. The balance of the increase was attributable to increased
professional services costs. Cost of service revenue as a percentage of service
revenue declined to 121% for 1998 from 335% for 1997, primarily as a result of
increased utilization of our expanded professional services organization.

     Sales and Marketing Expenses.  Sales and marketing expenses increased by
$1.8 million, or 140%, to $3.0 million for 1998 from $1.3 million for 1997.
Approximately $1.0 million of the increase was due to increased headcount in our
sales and marketing departments, and approximately $600,000 of the increase was
due to increased marketing communications expenditures associated with our
products and services. The balance of the increase was due to increased
commissions earned by sales personnel on higher dollar sales.

                                       29
<PAGE>   34

     Research and Development Expenses.  Research and development expenses
increased by $856,000, or 61%, to $2.3 million for 1998 from $1.4 million for
1997. Approximately $590,000 of the increase was related to increased staffing
and associated support costs for software engineers required to expand and
enhance our product and services offerings. The balance of the increase was
attributable to increased consulting costs related to the development and
enhancement of our product offerings.

     General and Administrative Expenses.  General and administrative expenses
increased by $409,000, or 55%, to $1.1 million for 1998 from $738,000 for 1997.
Approximately $250,000 of the increase was due to increased staffing and
associated expenses necessary to manage and support our growth. The balance of
the increase was attributable to increases in office expenses, outside services
and other general and administrative expenses.

     Other Income (Loss).  Other income (loss) increased by $171,000 from a loss
of $60,000 in 1997 to income of $111,000 in 1998. The increase was due primarily
to a loss of $101,000 recognized in 1997 on the disposal of fixed assets related
to a discontinued service offering.

</TABLE>


     We have experienced substantial fluctuations in our quarterly results of
operations and we expect those fluctuations to continue. For example, costs
related to the hiring of our chief executive officer during the three months
ended June 30, 1998 substantially increased our general and administrative
expenses in the quarter. During the third and fourth quarters of 1998, our cost
of service revenue grew more rapidly than our service revenue, due to increases
in personnel and recruiting expenses related to our initiative to increase the
capacity of our professional services organization. Sales and marketing expense
grew more rapidly in the third quarter of 1998 than in previous quarters due to
a substantial increase in the number of our field sales personnel, who typically
require initial training and may take several months to become fully productive.
Our results of operations in the fourth quarter of 1998 were also affected by
higher than usual cost of product revenue, attributable to license fees for
third-party software purchased during the quarter for resale by us as part of
our net.Analysis solution. In the fourth quarter of 1999, our sales and
marketing expenses increased significantly as a result of increased commissions
earned by our sales personnel for orders significantly above their quotas.
Because our 1999 compensation plans for our sales personnel were generally based
on the orders we booked rather than the revenue we recognized, commission costs
increased in an amount disproportionate to the increase in revenue in the
quarter. For the reasons described above, we believe that period to-period
comparisons of our historical operating results are not necessarily meaningful
and should not be relied upon as an indication of future performance.


LIQUIDITY AND CAPITAL RESOURCES

     Since our inception, we have financed our operations primarily through
private sales of preferred stock, resulting in net proceeds of $35.0 million
through December 31, 1999. To a lesser extent, we have financed our operations
through debt and lease financing. As of December 31, 1999, we had $9.6 million
in cash and cash equivalents and $7.4 million in working capital.

                                       31
<PAGE>   36

     As of December 31, 1999, we had cash and cash equivalents totaling $9.6
million, an increase from $2.3 million of cash and cash equivalents held as of
December 31, 1998. This increase resulted primarily from our sale of preferred
stock in June 1999, which provided net proceeds of $20.8 million, reduced by
cash used to fund operations and investing activities for 1999.

     Our operating activities resulted in net cash used of $2.7 million for
1997, $5.1 million for 1998 and $13.0 million for 1999, primarily due to
operating losses.

     Our investing activities resulted in net cash used of $3.9 million for
1999, primarily due to capital expenditures. Our investing activities resulted
in net cash provided of $960,000 for 1997 and $132,000 for 1998.

     Our financing activities resulted in net cash provided of $24.3 million for
1999, primarily due to our sale of preferred stock in June 1999 and issuance of
long-term debt. Our financing activities resulted in net cash provided of $1.3
million for 1997 and $7.0 million for 1998. Our financing activities in these
periods principally consisted of sales of preferred stock and borrowings under a
term loan agreement.


     We have a subordinated debt agreement providing for term loans of up to
$4.0 million and an equipment line of credit of up to $1.0 million with
Comdisco, Inc. The term loans and the equipment line are payable in 36 monthly
payments and bear interest at rates of 13.5% and 9%, respectively. The term loan
agreement provides for a prepayment penalty of 1% to be charged upon repayment
within twelve months of the closing date of the loan. As of December 31, 1999,
we had $2.7 million outstanding under the term loan agreement and $476,000
outstanding under the equipment line. In order to make additional borrowings
under these loan arrangements, we must maintain certain financial reporting and
other covenants. We were in compliance with these covenants as of December 31,
1999.


     Capital expenditures totaled $111,000 for 1997, $776,000 for 1998 and $3.6
million for 1999. Our capital expenditures consisted of purchases of property
and equipment, including computer equipment and software. We expect capital
expenditures to increase for the foreseeable future as we increase our number of
employees, increase the size of our operating facilities, and improve and expand
our information systems. Since inception, we have generally funded capital
expenditures either through the use of working capital or with equipment loans
and lease financing.

     As of December 31, 1999, we had net operating loss carryforwards of $25.5
million and research and development credit carryforwards of $586,000. The net
operating loss and credit carryforwards will expire at various dates through
2019, if not used. Under the provisions of the Internal Revenue Code,
substantial changes in our ownership may limit the amount of net operating loss
carryforwards that could be utilized annually in the future to offset taxable
income. We have established a full valuation allowance in our financial
statements to reflect the uncertainty of our ability to use available tax loss
carryforwards and other deferred tax assets.

     We expect to experience significant growth in our operating expenses for
the foreseeable future in order to execute our business plan. As a result, we
expect that operating expenses, as well as anticipated capital expenditures,
will constitute a material use of our cash resources. In addition, we may
utilize cash resources to fund acquisitions of, or investments in, complementary
products, services, businesses or technologies. We believe that the net proceeds
from the sale of common stock in this offering, together with our existing cash
and cash equivalents, will be sufficient to finance our operations through at
least the next 12 months. Thereafter, we may find it necessary to obtain
additional equity or debt financing. Any needed financing may not be available
to us on commercially reasonable terms, if at all.

YEAR 2000 STATUS

     The "year 2000" issue refers generally to the problems that some software
may have in determining the correct century for the year, which may result in
failures or the creation of
                                       32
<PAGE>   37

erroneous results. Many currently installed computer systems and software
products originally could not reliably distinguish dates beginning on January 1,
2000 from earlier dates. It is possible that some companies' software and
computer systems have not been upgraded or replaced in order to correctly
process dates beginning in 2000.

     To date, we are not aware that any year 2000 issues have affected our
business. Nonetheless, it may be too early to conclude that year 2000 issues
will not adversely affect our operations. Our business depends on the operation
of numerous systems that could be affected by year 2000 related problems. Those
systems include:

     - hardware and software systems we use to deliver services to our
       customers, including our proprietary software systems as well as hardware
       and software supplied by third parties;

     - communications networks, such as the Internet and private intranets,
       which we depend on to communicate both internally and with our customers
       and potential customers;

     - the internal systems of our customers and suppliers;

     - the hardware and software systems we use internally to manage our
       business; and

     - non-information technology systems and services we use in our business,
       such as telephone systems and building systems.

     Any year 2000 problems that affect these systems could adversely affect our
operations. We did not undertake a study of our customers' year 2000 readiness
nor did we undertake a study of the environments in which our software may be
deployed. Our testing and review procedures may not have been adequate to
identify all potential year 2000 issues with these systems. With regard to our
software products and services, our testing of net.Analysis version 4.0 and
later releases revealed no year 2000 issues that have not been remedied. Despite
testing by us and by current and potential clients, and assurances from
developers of products incorporated into our products, our products may contain
undetected errors or defects associated with year 2000 date functions. Known or
unknown errors or defects in our products could result in delay or loss of
revenue, diversion of development resources, damage to our reputation, or
increased service and warranty costs, any of which could seriously harm our
business. Some commentators have predicted significant litigation regarding year
2000 compliance issues, and we are aware of such lawsuits against other software
vendors. Because of the unprecedented nature of such litigation, it is uncertain
whether or to what extent we may be affected by it.

     We did not incur any material expenditures in connection with identifying
or evaluating year 2000 compliance issues. We neither developed nor intend to
develop a year 2000 contingency plan.

RECENTLY ENACTED ACCOUNTING STANDARDS

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument be recorded in
the balance sheet as either an asset or liability measured at its fair value.
SFAS No. 133, as recently amended, is effective for fiscal years beginning after
June 15, 2000. Because we do not currently hold any derivative instruments and
do not currently engage in hedging activities, we expect the adoption of SFAS
No. 133 will not have a material impact on our financial position or operating
results.

DISCLOSURES ABOUT MARKET RISK

     Based on the nature and current levels of our investments, we have
concluded that we have no material market risk exposure.

                                    BUSINESS

     We provide software and professional services that help our customers
understand, analyze and improve their online businesses. Our net.Analysis
software enables companies to collect, store, organize and analyze detailed
information about the online behavior of customers and other visitors on their
web sites. Through net.Analysis, our customers can also import and analyze
information about these e-customers available from other online and offline
software systems and databases. Our professional services organization provides
strategic analytic consulting and product integration and installation services.
This combined software and services solution enables companies to better tailor
and target their marketing initiatives, restructure their web sites to
facilitate e-commerce, provide more relevant and cost-effective content, improve
web site design, better allocate advertising and partnership resources, and
better plan their investments in web site hardware and software.

INDUSTRY BACKGROUND

  Growth of the Internet and Online Commerce

     The Internet has emerged as a global medium that allows millions of people
to obtain information, communicate and conduct business. As Internet usage has
grown, companies have increasingly come to rely on both web sites and private
intranets as important business channels. Through the Internet, a company can
establish and maintain large numbers of direct relationships while avoiding many
traditional investments in business infrastructure, such as retail outlets,
distribution networks and sales personnel. Both traditional and Internet-based
companies use the Internet to communicate marketing and other information to
current and potential customers and to manage relationships with vendors,
business partners, employees and others. Increasingly, companies are using the
Internet to generate revenue through the sale of goods and services or the sale
of advertising. In October 1999, International Data Corporation estimated that
revenue from Internet commerce would increase from approximately $50 billion in
1998 to approximately $1.3 trillion in 2003.

  Increasing Investments in Web Site Hardware and Software

     As use of the Internet increased and businesses became aware of its
potential, both traditional and Internet-based companies began to invest more
heavily in the development, design and support of their web sites. Early web
sites began merely as efforts to build corporate brand identity and contained
little more than general corporate and marketing information. Many companies
have now enhanced the content and features of their web sites, not only to
attract and retain customers, but also to better serve their customers' needs.
For example, companies focused on electronic commerce, or e-commerce, have spent
significant funds to purchase a variety of advanced third-party software
applications to ensure that customers have a satisfying online experience. These
include software applications to serve visitors an enormous variety and number
of web pages, present multimedia content and banner advertisements, and process
orders securely and fulfill them reliably.

     Continued competition among e-commerce businesses for e-customers has also
contributed to the trend toward increased web site functionality. For example,
to attract and retain customers and build long-term customer loyalty, many
companies are now seeking to provide more personalized service to their online
customers. Numerous software applications now enable companies to customize or
personalize their web sites based on customers' stated or implied preferences,
as well as their demographic and behavioral profiles, previous purchasing
history or other offline relationships with the company.

     To support this high level of functionality, companies must often manage
large databases and integrate specialized web applications with offline
applications and databases, including their transaction processing, financial
accounting and customer relationship management systems. As a

                                       34
<PAGE>   39

result, many web sites have become complex systems comprised of multiple,
geographically dispersed servers running a variety of software applications and
managing extremely large volumes of online visitor traffic.

  The E-Customer Intelligence Opportunity

     As companies have increased investments in their web sites and as those
sites have become more important to their overall business operations, they have
begun to devote more attention to establishing and achieving specific business
goals for their web initiatives. For many companies, the principal objectives of
their web sites are to better attract, serve and retain customers and more
effectively conduct e-commerce with them. Companies have also begun to evaluate
whether they have allocated their resources wisely among their various web
investments, such as online marketing campaigns, web site content, advertising
and other promotional sponsorships, and web site hardware and software. To
achieve these objectives, companies must understand the needs and behavior of
their online customers as well as the specific costs and benefits of each of
their web initiatives. Complicating matters, companies often desire to analyze
and understand the behavior of their e-customers in the context of their
traditional offline businesses.

     To gain an understanding of their e-customers, companies often initially
purchase inexpensive web site statistics reporting software. These solutions
generally provide basic information on web site traffic, but do not answer many
of the detailed questions that business professionals have about e-customer
behavior. Marketing executives and information technology professionals need
answers to critical questions, such as:

     - where do our online customers come from? which banner ad placements,
       affiliates and other online sponsorships generate the most visitors and
       customers for our web site? what are the best sources for new customers?

     - how do customers typically navigate our web site? how can we make our web
       site easier to use and more effective at selling our products and
       services? which pages do our best customers visit most often before
       making a purchase on our site?

     - what are the profiles of our best customer segments? how do their web
       site behavior and other characteristics differ from visitors who do not
       make purchases?

     - are our existing offline customers using our web site? which ones? how?

     - which web pages do visitors view the most often? is this content
       cost-effective?

     - how do our employees use our intranet? what content do they seek most
       often? how can we deliver information to our employees more effectively
       and reduce our support costs?

     - can our suppliers easily transact business with us from our web site?

     - from which page do most visitors leave our web site? is there a problem
       with that page? to which web sites do they go?

     - do we have enough hardware and software to support our web site traffic?
       what are the most common failures? if our web site traffic grows, what
       additional hardware and software should we buy?

     To answer these questions and develop actionable business plans, companies
need an easy-to-use system that gathers comprehensive e-customer intelligence.
Businesses also need professional consulting services to help them identify the
e-customer intelligence they can use to take full advantage of their online
business opportunities. They need highly functional analytical solutions and
robust, interactive reporting capabilities that will help marketing and
information technology personnel understand and draw conclusions from this
e-customer intelligence. They need analysis that they can readily put into
action in the form of improvements to their web sites and other online and
offline marketing initiatives, and they need to be able to judge the success of
those
                                       35
<PAGE>   40

initiatives. Most companies also require a system that is compatible with their
other web-based software applications, that will perform reliably in complex web
environments receiving millions of hits per day, and that can integrate with
their existing customer information systems to provide a comprehensive view of
their customer base.

THE NET.GENESIS SOLUTION

     We offer e-customer intelligence software that enables our customers to
collect store, organize and analyze information about the online activity of
visitors to their web sites. We also offer a range of related professional
services. Together, our software and related services provide our customers with
the following benefits:

     Comprehensive Customer Information.  With net.Analysis, companies can build
a comprehensive database of e-customer intelligence. net.Analysis collects and
stores extensive near real-time and historical information about the online
activity of customers, down to the level of each individual mouse-click. With
its net.Instrument module, net.Analysis also enables a company to import
customer information from third-party web applications and databases, as well as
information gathered by offline software, such as transaction histories, call
center logs, customer profiles and marketing campaign data. Once net.Analysis
has imported this other data, net.Analysis can organize and correlate this
information with other information in the net.Analysis database. This integrated
database provides a company with a comprehensive view of its online customers,
and grows more valuable over time as it accumulates increasingly detailed
information about the company's customers and their characteristics, preferences
and behavior.

     Powerful Analytical Capabilities.  net.Analysis provides powerful
analytical capabilities and flexible reporting options designed to serve the
business needs of different groups within a company, such as marketing
executives, information technology professionals or other business managers.
net.Analysis helps companies identify trends in customer behavior and purchasing
patterns and thereby assess and improve their marketing, advertising and
e-commerce initiatives. Users can select the data they wish to analyze, apply
filters that refine the data and navigate through the data to identify unusual
patterns and significant trends. net.Analysis presents data in a series of
interactive charts that can be expanded or narrowed to encompass more or less
data, enabling users to drill down to a level as specific as individual
customers' demographic profiles or their paths through a web site, or
clickstreams. For example, users can correlate specific marketing campaigns with
customer purchases to determine whether the campaign was effective in increasing
sales. Users can also match this data with customer profiles to identify the
customer segments that responded best to the marketing campaign. With this
information, companies can better tailor their web sites, marketing campaigns
and e-commerce initiatives to meet the needs of their online customers.

     Compatibility with Other Software Applications.  net.Analysis has an open
and extensible architecture, meaning that it is designed to be integrated with
third-party software applications and databases. This open architecture makes it
easier for companies to gather information from a broad range of data sources
and to incorporate net.Analysis into complex web sites. This flexible
architecture makes our software attractive to companies seeking e-customer
intelligence software that will integrate with their other web applications and
existing offline systems. net.Analysis also supports multiple operating
platforms, including Microsoft Windows NT and Unix. In addition, third parties
may seek to build add-on applications or include the capabilities of
net.Analysis in systems or services that they offer to their customers. For
example, other software companies may seek to enter original equipment
manufacturer agreements with us and incorporate net.Analysis in a suite of
integrated software applications. Similarly, application service providers, or
companies that offer the usage of software as a service to their customers, may
seek to license net.Analysis to provide advanced e-customer intelligence
services to others.

     High Performance, Reliable Solution in Complex Environments.  Because our
target market includes some of the busiest web sites on the Internet, we have
designed net.Analysis to perform reliably in complex web site environments
managing tens of millions to over 100 million hits per day. net.Analysis uses
sophisticated data collection techniques and algorithms to maintain its
performance speed, even when used to analyze data from large web sites hosted on
multiple servers in different locations. For example, a leading Internet media
provider relies on net.Analysis to produce daily reports that integrate customer
activity across 12 separate web sites that generate millions of hits per day. In
addition, because net.Analysis frequently operates in complex, integrated web
environments where other software applications may fail, we have built into
net.Analysis backup, recovery and alert mechanisms to preserve data during
failures and ensure its reliability as a business-critical application.

     Strategic E-Customer Intelligence Services.  We provide professional
consulting services to help companies understand the depth of critical business
information that net.Analysis can gather from customer activity on their web
sites. In addition to product installation and configuration, application
integration and training services, we provide advanced analytic consulting
services to assist companies in understanding their business needs, developing
web-based criteria for evaluating the performance of their online businesses,
and designing web site modifications and developing customized analyses and
reports to address their particular requirements.

     We believe our software and service offerings enable our customers to
achieve significant benefits in the following areas:

     - better targeted and tailored marketing initiatives.  net.Analysis
       provides rich behavioral profiles of different segments of online
       visitors, enabling marketing professionals to tailor online and offline
       marketing initiatives such as online promotions, e-mail campaigns, direct
       mail and other promotional efforts.

     - more effective efforts to generate e-commerce.  With net.Analysis,
       companies can understand the web usage behavior and purchasing patterns
       of their best online customers. That information enables them to target
       their content, features and online marketing campaigns to those customers
       and to prospects that resemble those customers. Also, companies can
       understand which marketing campaigns are ineffective and find ways to
       improve them.

     - more relevant and cost-effective content.  By giving detailed information
       on the relative popularity of products, services and content,
       net.Analysis gives online business managers information they can use to
       improve the content of their web sites and intranets or alter it to
       attract different customers. Content managers can also assess the level
       of interest in particular content and determine whether that content is
       cost-effective.

     - better web site design.  By helping web site designers understand how
       users navigate through a web site to reach the content they seek,
       net.Analysis enables designers to shorten the path to the most popular
       content and develop a more intuitive web site layout for both new and
       experienced users.

     - improved allocation of advertising and partnership resources.  By
       enabling companies to trace each step of every visitor's path from
       arrival at the web site to departure, net.Analysis helps companies
       identify which online advertisements or promotional sponsorships were
       most effective at achieving specific business goals, such as registering
       new users or increasing sales of particular products.

     - better planning of investments in web site hardware and
       software.  net.Analysis enables companies to better measure how their web
       sites perform under varying traffic loads and with different end-user
       access technologies. With this type of information, companies can better
       plan investments in building additional capacity and improving interfaces
       with new user technology.

STRATEGY

     Our objective is to be the leading provider of e-customer intelligence
software and services. Our strategy to achieve this objective includes the
following elements:

     Extend Leadership Position in E-Customer Intelligence Solutions.  We intend
to continue to devote significant resources to the development of leading
e-customer intelligence software and services for complex, high-traffic web
environments. We began developing our core technology in 1994, when few
companies had a commercial presence on the web, and have continued to build our
expertise in developing highly functional, scalable and reliable e-customer
intelligence solutions. We intend to continue to enhance net.Analysis' data
collection, analytical and reporting functions to provide a more comprehensive
view of online customer relationships and to integrate with leading online
commerce applications and third-party offline data sources. We also intend to
equip marketing and executive personnel with additional customer analysis,
segmentation and predictive modeling applications. For example, we recently
introduced CartSmarts, an add-on application to net.Analysis that helps
e-commerce companies better understand customers' online shopping behavior. We
also recently announced our net.Activator product development initiative, which
is intended to allow our customers to use the information gathered through
net.Analysis as direct input to other software applications, such as
applications for direct e-mail marketing campaigns and ad targeting.

     Expand Sales and Distribution Channels.  We believe the market for
e-customer intelligence software is only beginning to emerge in the United
States and is even less developed outside the United States. We intend to
significantly expand our direct sales force in the United States and in selected
locations in Europe and Asia to enhance our long-term competitive position. We
also plan to develop relationships with additional systems integrators, original
equipment manufacturers, resellers and application service providers in the
United States and abroad to augment the efforts of our direct sales force. In
particular, our business development organization is focused on establishing
relationships with systems integrators to take advantage of their substantial
service and distribution capabilities. We intend to continue to train selected
system integrators to provide the full range of our professional services
directly to customers. In addition, we may begin to use, or license application
service providers to use, net.Analysis to offer e-customer intelligence services
on a subscription basis to e-commerce sites that do not independently license
net.Analysis.

     Deepen Penetration into Installed Base of Customers.  As of December 31,
1999, we had an installed base of more than 200 customers in a broad range of
industries. Many of our customers purchase additional products and services from
us after the initial installation of net.Analysis. For example, in 1999, we
derived approximately 50% of our total revenue from sales of products and
services to customers that had made purchases from us before 1999. We believe
several trends will create additional opportunities to market our products and
services to our existing customers, including the intensifying competition among
web sites for visitor attention, enhanced web site functionality, better
integration of web sites with existing business systems, growing internal
pressures to demonstrate the value of investments in web sites, and demand for
professional consulting services in developing web-based performance
measurements. Moreover, as we develop new applications or product enhancements,
we believe our existing customer base will be a significant market opportunity
for those products and related services.

     Expand Strategic Technology Relationships.  We believe that an extensive
network of strategic technology alliances will enhance the attractiveness of our
product and service offerings and provide additional marketing and distribution
channels. We have established strategic relationships with a number of companies
to offer software that integrates with other technologies important to our
customers' online business initiatives. For example, we have developed
relationships with DoubleClick, IBM, Net Perceptions and Vignette to ensure that
our products integrate with each other or to conduct co-marketing or co-selling
activities. In addition, we intend to expand the distribution of our software by
licensing net.Analysis for incorporation into other web applications.

                                       38
<PAGE>   43

We intend to build upon our existing relationships and establish additional
strategic technology relationships with leading online commerce software
providers.

     Expand Professional Services Capabilities.  We believe there are
significant opportunities to expand our consulting services, particularly our
strategic analytic consulting services. We intend to significantly expand our
professional services capabilities to enable us to assist customers in
developing and measuring web-based performance criteria that are relevant to
their businesses and in addressing key business issues associated with
implementing large-scale, strategically important online businesses. In
addition, we believe that further developing our professional services
capabilities will allow us to develop close customer relationships that may lead
to additional sales and product development opportunities.

     Pursue Strategic Acquisitions.  We intend to pursue acquisitions of
products, services and technologies that complement our existing business.
Although we have no present commitments or agreements regarding any
acquisitions, we believe that numerous acquisition candidates could enhance our
e-customer intelligence capabilities.

PRODUCTS AND SERVICES

     We offer highly scalable, reliable and functional e-customer intelligence
software for high-traffic e-commerce web sites and other complex web
environments. We currently offer our net.Analysis software application and a
complementary application for analyzing online shopping behavior, as well as a
variety of strategic analytic consulting services, implementation consulting
services and other services.

  SOFTWARE PRODUCTS

     net.Analysis 4.5.  net.Analysis collects and analyzes valuable information
about the behavior of visitors to the user's web site, such as which web sites
the visitors came from, what behavior they demonstrated on the site, how much
time they spent in various sections of the site, whether or not

                                       41
<PAGE>   46

they made purchases, and other clickstream patterns. net.Analysis can then
correlate this data with the organization's other online and offline business
information to develop a comprehensive view of its online customers.

     We have designed net.Analysis to support the large and complex web server
configurations common to high-traffic web sites. net.Analysis directly supports
the most popular relational databases and enables fast data import and
processing. We currently offer versions of net.Analysis for three popular
operating systems: Microsoft Windows NT, Sun Solaris and IBM AIX. We introduced
our first version of net.Analysis in January 1996 and released version 4.5, the
latest version, in October 1999.

     The net.Analysis application includes the following modules:

     net.Stream.  net.Stream is high-performance data importing software for
collecting continuous streams of data regarding web site activity. net.Stream
enables the user to collect data from multiple sources, such as files of web
server transaction logs, or log files, network packet sniffers, which analyze
packets of data as they pass over the network, and web server plug-ins, which
are software modules that extend the standard information logged by the web
server. With net.Stream, business and technical managers have access to a mix of
near real-time and historical data reports to support both tactical and
strategic decision-making. At the option of the user, net.Stream can prepare
summaries of detailed clickstream data, which can improve the overall response
time for targeted queries of the database during an analysis.

     net.Instrument.  net.Instrument is an advanced integration application for
combining and correlating online visitor behavior data with business data from
other sources. net.Instrument enables the user to discover meaningful business
trends by integrating and analyzing information from third-party web
applications and from traditional offline databases, such as product and
customer databases. Through net.Instrument, net.Analysis provides a complete
view of the online customer in the context of the overall business, and can
offer drill-down and data correlation reports for all of the organization's
information on its e-customers. net.Instrument also establishes a platform on
which users can develop new modules to take advantage of information and
technology provided by their strategic partners. For example, PixelPark, one of
our solution providers, has used net.Instrument to integrate net.Analysis with
Intershop's commerce server, called Enfinity, to provide a broader view of
online visitors and their transactional behavior as a value-added offering.

     net.Analysis DataStore.  With net.Analysis, a company can compile a vast
database of e-customer intelligence, including both online and offline
information, which can become a valuable information asset. The net.Analysis
DataStore contains both complete transaction data as well as summaries of that
data. This design facilitates both quick analysis of high-level questions and
more thorough analysis of questions that require a fine level of detail. Through
net.Instrument's integration capabilities, a company can also correlate web site
activity data in the net.Analysis DataStore with customer information compiled
in other databases. This information can include data from third-party web
applications and from offline sources, such as transaction histories, customer
profiles and marketing campaign data. Once information has been stored or
correlated in the net.Analysis DataStore, the customer can apply all of
net.Analysis' analytical tools and reporting capabilities to that information to
better understand and use the data to improve business decisions.

     Reporting Capabilities.  net.Analysis' reporting modules include
net.Reporter, HTML Reporter, ReportSite and net.Dashboard. net.Reporter is a
software application that resides on the end-users' computers and serves as the
principal desktop interface for net.Analysis. From net.Reporter, end users
perform in-depth, ad hoc analysis of the characteristics of e-customers and
their web site activity. net.Reporter includes point-and-click wizards to help
create sophisticated, customized reports, filters that allow users to focus on
unique aspects of e-customer intelligence, and drill-down capabilities that
permit users to probe anomalies and identify trends important to their business
activities. net.Reporter provides over 150 pre-defined reports, report wizards
and data analysis filters. HTML Reporter allows users to generate pre-defined
reports through a browser-based
                                       42
<PAGE>   47

interface. ReportSite is a pre-built intranet site that uses a simple,
calendar-based interface to provide access to automatically published
net.Analysis reports. net.Dashboard is a Java-based desktop interface that
enables a personalized view of near real-time web site activity data. This fully
customizable extension to net.Reporter presents e-metrics for managers across
the enterprise.

     These modules enable a company to produce a wide variety of reports with
varying levels of detail to satisfy the wide-ranging web site analysis needs of
individuals throughout the company. Frequently used reports include:

        - Top Content Pages
        - Top Authors
        - Top Advertisers by Impressions
        - Top Advertisers by Clickthrough
        - Top Pages by Time Spent
        - Clickstream Path Report
        - Top Referring Web Sites
        - Visit Recency and Frequency (CartSmarts)
        - Purchase Recency and Frequency (CartSmarts)
        - Repeat Customers (CartSmarts)

     Administrator Console.  net.Analysis' Administrator Console is a
browser-based administrative interface through which our customers can automate
and refine the web site analysis reporting process, from data collection to
report production and distribution. Our customer's net.Analysis administrator
can configure and manage net.Analysis data files, and can automate data
retrieval, importing, compression and storage on an hourly, daily, weekly or
monthly basis. Other data parameters can also be adjusted based on the needs of
the customer's business. For example, the Administrator Console permits the
administrator to adjust data collection parameters to collect all available data
or to sample the data.

     Licensing and Pricing.  We license net.Analysis according to the number of
managed servers and according to the number of end users of net.Analysis'
reporting capabilities. Each net.Analysis license includes the net.Analysis
application and a single end-user license for net.Reporter, HTML Reporter and
ReportSite. Every license also includes maintenance and support for twelve
months. Pricing for net.Analysis varies according to the platform for which it
is purchased. Pricing for additional end-user access to net.Reporter, HTML
Reporter and ReportSite increases according to the number of end users in the
customer's organization. The price of an entry-level system, including software
and related professional services, ranges from approximately $50,000 to
$100,000. We offer annual maintenance and support renewals for a fee based on a
percentage of the then-current list price of the installed applications. We
offer premium and customer support services for additional fees.

  ADD-ON APPLICATION TO NET.ANALYSIS

     CartSmarts.  CartSmarts provides online shopping analysis and reporting.
CartSmarts includes more than 40 pre-defined reports and filters specifically
for evaluating shopping behavior as customers progress through the purchase
process. These specialized online shopping reports include the following:

     - Purchase Path Report, which enables businesses to understand how visitors
       progress through or abandon each stage of the purchase process

     - Shopping Cart Activity Report, which enables businesses to understand how
       their customers use shopping carts, why they may abandon them at specific
       stages of the purchase process, and which purchases they complete

     - Acquisition Source Report, which enables users to understand which sites
       refer the best potential customers

PROFESSIONAL SERVICES

     We offer a range of professional services, including strategic analytic
consulting, product implementation, application integration, training programs
and technical support. We began to expand our professional services organization
significantly in 1998 and intend to continue to hire additional employees for
this department. We price our professional services primarily on a time-
and-materials basis and to a lesser extent on a fixed-price basis.

     Strategic Analytic Consulting Services.  We offer strategic analytic
consulting services primarily to customers that operate complex, high-traffic
web sites and customers that are developing or managing sophisticated online
businesses. We provide advanced consulting services to assist companies in
understanding their business needs, developing web-based performance
measurements, and designing web site modifications and developing customized
analyses and reports to address their particular requirements. We have also
developed a formalized web site analysis methodology, Design for Analysis, that
assists customers in designing or redesigning their web sites in ways that
facilitate analysis and reporting of their online businesses. Our professional
service organization also helps customers to plan cost-effective e-customer
intelligence strategies by, for example, evaluating trade-offs between the value
of storing massive quantities of data and the hardware, software and
organizational costs associated with that storage. We also assist customers in
interpreting their data, identifying trends and designing appropriate action
plans.

     Product Implementation and Application Integration Services.  We offer a
variety of product implementation consulting services, including FastPath.
FastPath services enable a customer to rapidly begin using net.Analysis and
includes an assessment of the customer's needs, product installation and
configuration, and introductory training. Application integration consulting
covers a broad array of services, including customization of net.Analysis
reports, integration with third-party web and offline applications and
databases, and the development of special software for unique customer
situations. On a limited basis, we have also provided for a fee ongoing data
management, analysis and reporting remotely from our offices.

     Training Programs.  Through our training programs, we help customers use
our products effectively and achieve their online business goals. We provide
instruction in the development, use and administration of net.Analysis to
marketing, business analysis, web site design and information technology
professionals and other end users. We offer courses at our training facilities
as well as at customers' locations. We also work closely with our solution
providers to train them in the use and extension of net.Analysis so they can
independently deliver professional services relating to net.Analysis.

     Technical Support Services.  Basic technical support services includes
product maintenance and phone, e-mail and web site support. For an additional
fee, we also offer premium and custom support services for customers with
special support needs.

     Since 1996, the majority of our research and development activities have
been directed towards creating new versions of our net.Analysis product to
extend and enhance its features, particularly its scalability, its ability to
integrate with other online and offline software applications and databases, and
its analytic capabilities. We intend to continue our investments in these areas
as well as in certain add-on technologies and applications, such as
net.Activator, a recently announced product development initiative. With
net.Activator, we intend to introduce an add-on application that will permit
organizations to use the information collected by net.Analysis as direct input
to other software applications, such as applications for direct marketing
campaigns and ad targeting.

     We have invested significant resources in developing an open and extensible
architecture to comply with widely accepted commercial software industry
standards for building large-scale Internet applications. We develop most of our
software in C++ and Java, two widely accepted

                                       44
<PAGE>   49

programming languages for application development. In addition, net.Analysis
meets ABC Interactive's standards for accuracy for independent verification of
online visitor information. Adherence to industry standards provides
compatibility with existing applications, simplifies the modification of our
software, and reduces the customer's need to purchase new software.

     We have focused our product development efforts in particular on developing
our software architecture to comply with eXtensible Markup Language, or XML, a
recently adopted standard for data representation and processing. We are also
actively developing and promoting a new initiative, known as Customer Profile
Exchange, or CPEX, a global standard for privacy-enabled customer data
interchange. Because we expect that the XML and CPEX standards will be widely
adopted in our industry, we believe that our initiatives with regard to these
standards will allow us to further our technology leadership position.

TECHNOLOGY

     We believe that net.Analysis excels in areas essential to complex,
high-traffic online businesses: scalability and performance, analytic
capabilities, compatible design and reliability.

     Highly Scalable Data Import Software Design.  We have designed net.Analysis
to meet the needs of customers with high-traffic web sites that process tens of
millions to over 100 million hits per day. net.Analysis works effectively with
large, complex web sites that have multiple, geographically distributed data
centers operating a mix of web server applications. We built our software around
our net.Stream technology, a highly scalable data import software design that
collects continuous streams of data regarding web site activity. The software
collects data from web server log files, network packet sniffers and web server
plug-ins. net.Analysis consolidates all the information from these disparate
data centers into one, chronologically ordered thread, enabling a coherent view
of web activity across the enterprise. net.Analysis avoids importing unwanted
data, such as activity caused by automated indexing by search engines.
net.Analysis then transforms the imported data into meaningful information for
subsequent analysis.

     net.Analysis applies a number of rules for sorting and grouping web-related
data to extract a sophisticated model of users and their behavior from low-level
visitor session information. net.Analysis tracks information about activities
such as promotion responses, e-commerce transactions and advertising
clickthroughs for subsequent analysis. These data importing and tracking
techniques provide a coherent and complete view of visitor activity on our
customer's web site.

     net.Analysis imports, manages and stores the complete history of each user
visit, which can result in extremely large volumes of data, particularly in
high-traffic environments. To maintain performance while analyzing these large
amounts of data, net.Analysis offers end-users the option to analyze groups of
similar data regarding web site behavior, while maintaining the underlying
information on the details of each user interaction. This method improves the
overall response time for queries of the database during an analysis. We
designed net.Analysis to take advantage of the benefits of each database
platform that it supports.

     We have designed the net.Analysis DataStore schema for high performance.
net.Analysis DataStore has both a transactional schema and a constellation
schema. The transactional schema is designed for loading large amounts of data
on a consistent basis and the constellation schema is designed for ad hoc,
interactive analysis. The schema also permits the efficient use of sophisticated
database resources, such as parallelized queries, for high scaling and
performance.

     Analytic Capabilities.  We have designed net.Analysis to provide multiple
analytic interfaces to meet the needs of different information consumers. The
most powerful of these interfaces is net.Reporter. net.Reporter allows for the
creation of custom reports as well as in-depth, ad hoc analysis. net.Reporter's
flexible interface allows users to establish business rules, concentrate on
particular segments of users, and compare those segments with one another by
building, combining and applying reusable filters. In addition, we have designed
a rich set of point-and-click wizards to simplify the process of creating
sophisticated custom reports.

     net.Analysis is designed to analyze dynamic web sites effectively. We have
included capabilities such as our Key Value Analysis, which enables users to
analyze web sites that employ dynamic content-serving technology. These
capabilities provide insight on how visitors use online forms and search engine
keywords and respond to banner advertising.

     Standard, Compatible Design.  We have built net.Analysis using a
standards-based, compatible design that allows customers to easily manage
net.Analysis and integrate it with their existing hardware and software.
net.Analysis supports Microsoft Windows NT, Sun Solaris and IBM AIX. In
addition, net.Analysis directly supports standard relational databases such as
Oracle, Microsoft SQL Server, Sybase and Informix.

                                       46
<PAGE>   51

     We have designed net.Analysis to combine and correlate data from a
company's other databases and applications with data regarding the behavior of
its online customers. This capability extends the power of net.Analysis in two
ways. First, it allows net.Analysis to flexibly interact with the company's
existing hardware and software and enhances the value of the company's existing
customer information resources. Second, it enhances the analytic capabilities of
net.Analysis by enabling end users to pursue more sophisticated questions about
visitor behavior on their sites.

     With its compatible design, net.Analysis can be easily incorporated into
complex web environments and can be used as a platform upon which customers can
build additional applications, such as PixelPark's integration of net.Analysis
with Intershop's commerce server.

     Reliability.  We have designed net.Analysis to serve as a software
application on which companies, including large-scale enterprises with vast
amounts of data to manage, can rely in their everyday business decisionmaking.
To that end, we have incorporated technologies that are designed to simplify
system administration and oversight, such as automated scheduling facilities to
handle data collection, data archival and report publishing. We have also
incorporated automated monitoring and alerting features to manage these
processes, as well as recovery systems to minimize the impact of power failures,
third-party application faults and system overloads. In addition, we have
developed an application to allow customers to integrate net.Analysis with
systems management applications. We believe the combination of these design
elements makes net.Analysis suited to serve as a business-critical component of
a company's information technology system.

STRATEGIC TECHNOLOGY RELATIONSHIPS

     To provide our customers with a complete solution, ensure that our own
products are compatible with the most advanced available technology and increase
the reach of our sales and marketing efforts, we have established relationships
with a select group of software and service providers that we believe are
leaders in their respective markets. Our relationships with these companies may
include joint development efforts directed at integrating our respective
products, joint participation in trade shows, seminars or user conferences, or
reciprocal product and sales training. We believe that our association with
these companies benefits our customers and helps to position us as a technology

SALES AND MARKETING

     We sell net.Analysis worldwide through our direct sales force and, to a
lesser extent, through relationships with resellers and other strategic
partners. As of January 15, 2000, our sales force consisted of 40 sales
professionals located in Atlanta, Boston, Chicago, Cupertino, Dallas, Los
Angeles, New York, Raleigh, Tampa and London. Our direct sales force focuses on
selling net.Analysis to customers that maintain strategic, high-traffic
commercial web sites. We utilize sales teams consisting of both sales and
technical professionals who work directly with potential customers, or with our
partners, to provide proposals and demonstrations designed to address the
specific needs of potential customers. We intend to increase our direct sales
force, both

                                       48
<PAGE>   53

domestically and abroad, and to develop relationships with additional resellers,
systems integrators, original equipment manufacturers and application service
providers.

     We have established relationships with web solution providers in numerous
domestic and international locations to augment our ability to offer our
products and services. Several of our solution providers are authorized
resellers of our products and have completed the training we require to provide
professional consulting services, technical integration services and technical
support on our behalf.

     We intend to license our software to other software and service companies
for incorporation into their e-commerce and other application suites, such as
with Harte-Hanks. In addition, we intend to license our software to companies
that may resell our solution as a subscription service offering.

     We focus our marketing efforts on creating awareness of our solution among
business executives, marketing professionals, web administrators and other
information technology professionals considering large-scale e-customer
intelligence solutions. We conduct a variety of marketing programs worldwide to
educate our target market. We have engaged in marketing activities such as
online seminars and promotions, direct marketing, trade shows, press and
industry analyst relations, and users conferences. We invest substantial effort
in our web site to support our corporate image in the online business community
and to generate sales leads. We make available on our web site extensive product
information, including a virtual tour of common business scenarios, which shows
online visitors typical applications of our product by marketing, advertising,
information technology and executive-level employees. Our marketing organization
works closely with our customers, direct sales organization and partners to
capture, organize and prioritize customer feedback to help guide our product
development organization.

COMPETITION

     The market for e-customer intelligence software and other web site analysis
software and related services is immature, fragmented, intensely competitive,
rapidly evolving and subject to rapid technological change. We expect that
competition will continue to intensify. Increased competition may result in
reduced market acceptance of our products, price reductions and reduced gross
margins, any of which could seriously harm our business. Competitors vary in
size and in the scope and breadth of the products and services they offer. Our
competitors include:

     - other companies developing and offering stand-alone e-customer
       intelligence and web site analysis software, such as Accrue, Macromedia
       (with its recent acquisition of Andromedia) and WebTrends

     - web application companies whose products have some of the functionality
       of our products, such as Microsoft, which includes web site statistical
       reporting in its Site Server software

     - companies offering traditional offline business intelligence or decision
       support solutions

     - providers of service-based solutions

     - internal development groups within prospective customers' organizations

     Some of our current and potential competitors have longer operating
histories and significantly greater financial, technical, marketing and other
resources than we do. They have significantly greater name recognition and a
larger installed base of customers. In addition, many of our competitors have
well-established relationships with our current and potential customers. In the
past, we have lost potential customers to competitors for various reasons and
may continue to do so. In addition, current and potential competitors have
established or may establish cooperative relationships among themselves or with
third parties to increase the ability of their products to address customer
needs. Companies marketing Internet applications that are currently
complementary to our products could incorporate into their products enhanced
analytic and reporting functionality that could adversely affect demand for our
software and services. For example,
                                       49
<PAGE>   54

Vignette recently acquired DataSage. Accordingly, new competitors or alliances
among competitors may emerge and rapidly acquire significant market share.

     We believe that the principal competitive factors in the market for our
products are:

     - the ability of a product to scale and support the requirements of
       complex, high-traffic web sites

     - depth of reporting and analysis capabilities

     - data collection capabilities and techniques

     - ability to integrate with the customer's web environment, and offline
       applications and data

     - ability to offer strategic professional services

     - quality of customer support

     - price

Although we believe that our solution competes favorably with respect to these
factors, our market is relatively new and is developing rapidly. We may not be
able to maintain our competitive position against current and potential
competitors, especially those with significantly greater financial, marketing,
service, technical and other resources.

EMPLOYEES

     As of January 15, 2000, we had 160 full-time employees, including 40 in
sales, 39 in engineering, 34 in professional services and technical support, 25
in general and administrative, and 22 in marketing and business development.
None of our employees is represented by a labor union, and we have never
experienced a work stoppage. We believe that our relations with our employees
are good.

FACILITIES

     Our headquarters are located in Cambridge, Massachusetts, where we lease
approximately 25,000 square feet of office space under a lease expiring in
August 2004. We expect that these facilities will meet our needs through
mid-2000 and that suitable additional or substitute space will be available as
needed. We also lease sales and service offices in Cupertino and London. We
lease these offices under agreements with remaining terms of less than two
years.

LEGAL PROCEEDINGS

     We are not currently subject to any material legal proceedings.

and holds office until his or her successor is elected and qualified or until
his or her earlier resignation or removal. There are no family relationships
among any of our directors and executive officers.

BOARD COMMITTEES

     Our board of directors established an audit committee in December 1999. The
audit committee consists of Robert N. Goldman, Rory T. O'Driscoll and Stephen J.
Ricci. The audit committee reviews our internal accounting procedures, evaluates
our audit and control functions, and reviews the results and scope of the audit
and other services provided by our independent public accountants.

1999. The compensation committee consists of Kathleen L. Biro and Ted R.
Dintersmith. The compensation committee reviews and recommends to the board of
directors the compensation and benefits of our officers and directors and
administers and grants options under our stock plans. The compensation committee
also establishes and reviews general policies relating to the compensation and
benefits of our employees.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     No member of our board of directors or our compensation committee serves as
a member of the board of directors or compensation committee of any entity that
has one or more executive officers serving as a member of our board of directors
or compensation committee.

DIRECTOR COMPENSATION

     All of our directors are reimbursed for expenses incurred in attending
meetings of the board of directors and its committees. In addition, our
non-employee directors are eligible to receive automatic grants of stock options
under our 1999 Stock Incentive Plan. Currently, we do not otherwise compensate
directors for their services as members of the board of directors or any
committee of the board. In connection with the election of Kathleen L. Biro to
our board, we granted her an option on April 12, 1999 to purchase 18,750 shares
of common stock at an exercise price of $0.67 per share. The option vests as to
one third of the shares subject to the option on April 12, 2000 and as to an
additional 8.33% of those shares each quarter thereafter until fully vested.

     Each non-employee director will receive an option to purchase 18,750 shares
of our common stock on the effective date of this offering. These options will
vest in annual installments over three years from the date of grant. In
addition, each non-employee director will receive an option to purchase 3,750
shares of our common stock on the date of each annual meeting of stockholders
commencing with the 2000 annual meeting of stockholders. These options will be

     In 1999, in addition to the compensation stated in the foregoing table, we
also provided each of our full-time employees with term life insurance in an
amount equal to their annual salary. Because we pay a single premium for the
entire group of employees, we are unable to calculate the dollar amount of the
premium attributable to any particular employee. Mr. Hodskins resigned from his
employment with us effective January 31, 2000.

     All options described in the foregoing table vest as to 25% of the shares
subject to the option on the first anniversary of the date of grant and as to an
additional 6.25% of such shares each quarter thereafter until fully vested.
However, each executive officer may exercise his or her options at any time upon
entering into a stock restriction and repurchase agreement containing an

                                       55
<PAGE>   60

identical vesting schedule. See "Transactions with Related Parties--Acceleration
of Stock Option Vesting for Executive Officers."

     The percentage of total options is based on an aggregate of 1,308,337
options that we granted during 1999 to our employees, including the named
executive officers. We granted these options with an exercise price equal to the
fair market value of our common stock on the date of grant, as determined in
good faith by our board of directors. All of the options have a term of 10
years, subject to earlier termination in the event of a termination of
employment. The exercise price for all options may be paid in cash, shares of
common stock, or a combination of cash and shares.

     The potential realizable values are based on the assumption that our common
stock will appreciate at the annual rate shown, compounded annually, from the
date of grant until the expiration of the ten-year term. These numbers are
calculated based on SEC requirements and do not reflect our projections or
estimates of future stock price growth. Actual gains, if any, on stock option
exercises will depend on the future performance of the common stock. This table
does not take into account any appreciation in the price of our common stock
from the date of grant to the current date. The values shown are net of the
option exercise price, but do not reflect deductions for taxes or other expenses
associated with the exercise.

</TABLE>

     The value realized upon exercise of an option equals the difference between
the fair market value of our common stock on the date of exercise, minus the per
share exercise price, multiplied by the number of shares purchased. The value of
unexercised in-the-money options equals the difference between the fair market
value of our common stock on December 31, 1999, minus the per share exercise
price, multiplied by the number of shares underlying the option. Accordingly,
solely for purposes of this table we have assumed that the fair market value of
our common stock throughout 1999 was $12.00 per share, the assumed initial
public offering price. In 1999, we entered into arrangements with some of our
executive officers to accelerate the vesting of their options upon the
conditions described in "Transactions with Related Parties--Acceleration of
Stock Option Vesting for Executive Officers."

EMPLOYEE BENEFIT PLANS

  1995 Stock Option Plan

     In 1995, our board adopted and our stockholders approved the 1995 stock
option plan and reserved 987,606 shares of common stock for issuance under the
plan. In July 1998, we amended the

                                       56
<PAGE>   61

plan to increase the number of shares authorized for issuance under the plan to
3,000,000. In September 1999, we amended the plan to increase the number of
shares authorized for issuance under the plan to 3,750,000. On January 26, 2000,
options to purchase a total of 1,582,180 shares of common stock were outstanding
under the 1995 plan. These options had a weighted average exercise price of
$1.58 per share. In connection with the adoption of the 1999 stock incentive
plan described below, the board terminated further issuances of options under
the 1995 plan.

     The 1995 plan authorizes the grant of options to purchase common stock
intended to qualify as incentive stock options, as defined in Section 422 of the
Internal Revenue Code, and nonstatutory stock options. The exercise price of
incentive options granted under the 1995 plan must be at least equal to the fair
market value of our common stock on the date of grant. The terms of these
options may not exceed ten years. The exercise price of incentive options
granted to an optionee who owns stock possessing more than 10% of the voting
power of our outstanding capital stock must be at least equal to 110% of the
fair market value of the common stock on the date of grant. This type of
optionee must exercise his or her option within five years from the date of
grant.

     The 1995 plan provides that, upon a change of control of our company:

     - all outstanding options will be exchanged for similar options of the
       corporation surviving any change of control

     - the vesting of all outstanding options will be accelerated by twelve
       months

For these purposes, a "change of control" means the occurrence of any of the
following:

     - any person becomes a beneficial owner, directly or indirectly, of 50% or
       more of the combined voting power of our outstanding shares

     - any merger or consolidation of net.Genesis with another company, other
       than a merger or consolidation in which our voting shares outstanding
       immediately before the merger or consolidation represent more than 50% of
       the combined voting power of the voting shares of the surviving entity

     - the liquidation, sale or disposition of all or substantially all of our
       assets

     The 1995 plan is administered by the compensation committee of our board of
directors.

  1999 Stock Incentive Plan

     In December 1999, our board of directors adopted and our stockholders
approved our 1999 stock incentive plan. The 1999 plan initially authorizes the
issuance of up to 2,625,000 shares of our common stock and authorizes an
additional 375,000 shares of our common stock on each of the first three
anniversaries of the date of adoption of the plan. On January 26, 2000, options
to purchase a total of 478,500 shares of common stock were outstanding under the
1999 plan.

     The 1999 plan authorizes the grant of options to purchase common stock
intended to qualify as incentive stock options, as defined in Section 422 of the
Internal Revenue Code, and nonstatutory stock options. The 1999 plan also
provides for awards of stock appreciation rights, performance shares, restricted
stock and other stock-based awards.

     Our officers, directors, employees, consultants and advisors are eligible
to receive awards under the 1999 plan. No participant may receive awards for
over 750,000 shares of common stock in any calendar year.

     Incentive options may be granted under the 1999 plan to our employees and
employees of our affiliates within the meaning of the Internal Revenue Code,
including our officers and directors as well as officers and directors of our
affiliates who are also employees. The exercise price of incentive options
granted under the 1999 plan must be at least equal to the fair market value of
our common stock on the date of grant. The exercise price of incentive options
granted to an optionee

                                       57
<PAGE>   62

who owns stock possessing more than 10% of the voting power of our outstanding
capital stock must be at least equal to 110% of the fair market value of the
common stock on the date of grant. This type of optionee must exercise his or
her option within five years from the date of grant.

     Under the terms of the 1999 plan, we may grant nonstatutory options to our
officers and other employees, our directors, and other individuals providing
services to us. There are no limits on the exercise price of nonstatutory
options granted under the 1999 plan.

     Under the terms of the 1999 plan, non-employee directors will also receive
certain automatic option grants as described in "Management -- Director
Compensation."

     The 1999 plan provides that, upon a change of control of our company:

     - all outstanding options will be exchanged for similar options of the
       corporation surviving any change of control

     - the vesting of all outstanding options will be accelerated by twelve
       months

For these purposes, a "change of control" has the same meaning as under the 1995
plan.

     The 1999 plan is administered by the compensation committee of the board of
directors. The compensation committee selects the individuals to whom awards
will be granted and determines the exercise price and other terms of each award,
subject to the provisions of the 1999 plan.

  1999 Employee Stock Purchase Plan

     In December 1999, our board of directors adopted and our stockholders
approved our 1999 employee stock purchase plan. The stock purchase plan
initially authorizes the issuance of up to 225,000 shares of our common stock
and authorizes an additional 52,500 shares of our common stock on each of the
first three anniversaries of the date of adoption of the plan.

     All of our employees who have completed three months of employment and
whose customary employment is more than 20 hours per week and for more than five
months in any calendar year are eligible to participate in the stock purchase
plan. Employees who own stock and hold outstanding options to purchase stock
representing five percent or more of the total combined voting power or value of
all classes of our stock are not eligible to participate in the stock purchase
plan.

     At the commencement of each designated payroll deduction period, or
offering period, an eligible employee may authorize us to deduct between 1% to
10%, in increments of 1%, of his or her base pay. On the last business day of
the offering period, we will deem the employee to have exercised the option, at
the exercise option price, to the extent of accumulated payroll deductions. The
purchase price will be 85% of the closing market price of our common stock on
either the first or last business day of the offering period, whichever is
lower.

     No employee is allowed to buy shares of common stock worth more than
$25,000, based on the fair market value of the common stock on the first day of
the offering period, in any calendar year under the plan.

     The stock purchase plan is administered by the compensation committee of
the board of directors.

  401(k) Plan

     We have adopted an employee savings and retirement plan qualified under
Section 401 of the Internal Revenue Code and covering all of our employees.
Employees may elect to reduce their current compensation by up to the
statutorily prescribed annual limit and have the amount of the reduction
contributed to the 401(k) plan. We may make matching or additional contributions
to the 401(k) plan in amounts to be determined annually by our board of
directors.

EMPLOYMENT AGREEMENT

     On May 28, 1998, we hired Lawrence S. Bohn to serve as our President and
Chief Executive Officer and we entered into an employment agreement and a stock
restriction and repurchase agreement with him. Under the employment agreement,
we agreed to employ Mr. Bohn as our President and Chief Executive Officer at an
annual salary of $150,000, which our board may increase annually. We also agreed
to pay Mr. Bohn a signing bonus of $51,750 upon the commencement of his
employment and a 1999 tax bonus of $36,000 on April 1, 1999. The agreement does
not specify a term of employment; rather, Mr. Bohn remains an employee-at-will.
Under the agreement, Mr. Bohn is entitled to participate in any bonus, group
health, medical reimbursement or life insurance programs that we may offer.

     Mr. Bohn used the $51,750 signing bonus we paid him under the employment
agreement to purchase, on a restricted basis, 776,250 shares of our common stock
at a price of approximately $0.07 per share, which our board of directors
determined was the fair market value of the common stock on the date of
purchase. Under the terms of the stock restriction and repurchase agreement, we
have the right to repurchase these shares of restricted stock if Mr. Bohn's
employment is terminated. Our right to repurchase these shares of restricted
stock expires in 48 equal monthly installments. Upon the closing of this
offering, our right to repurchase these shares of restricted stock will expire.

     Under the employment agreement, we must pay Mr. Bohn severance payments in
an amount equal to the salary and bonus paid to him over the immediately
preceding 12 months if his employment is terminated:

     - by us without good cause, which means dishonesty, any misappropriation of
       our assets, gross failure to perform his duties, the commission of any
       felony or any crime involving moral turpitude, or any breach of his
       obligations under his confidentiality, assignment of inventions and
       non-competition agreement with us

     - upon a change of control of net.Genesis

     - as a result of any attempt by us to force Mr. Bohn to relocate
       involuntarily his place of employment by more than 100 miles from
       Cambridge, Massachusetts

     - as a result of any action by us that has the effect of significantly
       diminishing his level of responsibility as President and Chief Executive
       Officer

     We also agreed to use our best efforts to cause Mr. Bohn to be elected to
our board of directors. The employment agreement further provides that if Mr.
Bohn's employment is terminated for any reason, he will be deemed to have
resigned as a director and from all other positions with net.Genesis. While Mr.
Bohn serves as our Chief Executive Officer, he is entitled to approve the
appointment of any Chairman of the Board.

SEPARATION AGREEMENT

     On January 14, 2000, we entered into a separation agreement with Roger
Hodskins, our former Vice President, Worldwide Sales and Service. Under the
agreement, Mr. Hodskins resigned his employment, effective January 31, 2000. We
agreed to continue to pay Mr. Hodskins his current base salary until at least
August 1, 2000, with a possible extension until November 1, 2000 if Mr. Hodskins
has not obtained alternative employment by that time. We also agreed to pay Mr.
Hodskins additional amounts equal to one-half of his maximum bonus for 1999. Mr.
Hodskins is entitled to participate in our insurance and other employee benefit
programs until July 31, 2000. We also agreed that the shares of restricted stock
that Mr. Hodskins purchased from us would continue to vest until August 5, 2000.

LIABILITY LIMITATIONS AND INDEMNIFICATION

     Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law permits a corporation to
provide that its directors will not be personally liable for monetary damages
for breach of their fiduciary duties as directors, except liability for:

     - any breach of their duty of loyalty to the corporation or its
       stockholders

     - acts or omissions that are not in good faith or that involve intentional
       misconduct or a knowing violation of law

     - unlawful payments of dividends or unlawful stock repurchases or
       redemptions

     - any transaction from which the director derived an improper personal
       benefit

     The limitations do not apply to liabilities arising under the federal
securities laws and do not affect the availability of equitable remedies,
including injunctive relief or rescission.

     Our certificate of incorporation and by-laws provide that we will indemnify
our directors and officers, and may indemnify other employees and agents, to the
maximum extent permitted by law. We believe that indemnification under our
by-laws covers at least negligence and gross negligence on the part of
indemnified parties. Our by-laws also permit us to secure insurance on behalf of
any officer, director, employee or agent for any liability arising out of
actions in his or her capacity as an officer, director, employee or agent,
regardless of whether the by-laws would permit indemnification. We have obtained
an insurance policy that insures our directors and officers against losses,
above a deductible amount, from specified types of claims. We believe that these
provisions and policies are desirable to help us attract and retain qualified
persons as directors and executive officers.

     The limited liability and indemnification provisions in our certificate of
incorporation and by-laws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful, might otherwise benefit us and our
stockholders. A stockholder's investment in us may be adversely affected to the
extent we pay the costs of settlement or damage awards against our directors and
officers under these indemnification provisions.

     At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees in which indemnification is sought, nor are
we aware of any threatened litigation that may result in claims for
indemnification.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to our directors, officers and controlling persons under our
certificate of incorporation or by-laws, we have been advised that in the
opinion of the SEC this indemnification is against public policy as expressed in
the Securities Act and is, therefore, unenforceable.

                       TRANSACTIONS WITH RELATED PARTIES

SALES OF PREFERRED STOCK

     A number of our directors, executive officers and stockholders beneficially
owning more than 5% of our common stock have participated in transactions in
which they purchased shares of our preferred stock. We believe that we sold
these shares at their fair market value and that the terms of these transactions
were no less favorable than we could have obtained from unaffiliated third
parties. The following table summarizes these transactions:

SALE OF COMMON STOCK TO LAWRENCE S. BOHN

     On May 28, 1998, in connection with the employment of Lawrence S. Bohn as
our President and Chief Executive Officer, we issued and sold to Mr. Bohn
776,250 shares of our common stock for approximately $0.07 a share, which our
Board of Directors determined to be the fair market value of our common stock at
the time. On the same date, we entered into a stock restriction and repurchase
agreement with Mr. Bohn providing that if he ceases to be employed by us prior
to the full vesting of his shares, we may repurchase the unvested shares for
approximately $0.001 per share. This option to repurchase lapses in 48 equal
monthly installments, calculated from March 23, 1998. The stock restriction and
repurchase agreement will terminate upon the closing of this offering.

LOAN TO LAWRENCE S. BOHN

     On May 4, 1999, Mr. Bohn exercised an option to purchase 607,500 shares of
our common stock at an exercise price of $0.16 per share. This option was
accelerated as described below. We loaned Mr. Bohn $96,390 towards this
purchase. The full recourse loan is evidenced by a promissory note from Mr. Bohn
to us. The loan is secured by the 607,500 shares of common stock that Mr. Bohn
purchased.

ACCELERATION OF STOCK OPTION VESTING FOR EXECUTIVE OFFICERS

     We have made arrangements with our executive officers to accelerate the
vesting of their options in full if they enter into stock restriction and
repurchase agreements with us. Under the stock restriction and repurchase
agreements, if an executive officer ceases to be employed by us before any of
the shares purchased would otherwise have vested under the option agreement, we
have the right to repurchase those shares at the same price for which the
officer purchased them. The following table provides information regarding the
executive officers who have entered into these arrangements with us, the date of
the transaction, the exercise price and number of options that were accelerated,
the number of shares purchased (including shares that were already vested and
therefore not subject to any stock restriction and repurchase agreement), and
the extent to which acceleration of vesting of the shares purchased will occur
upon a change in control of our company.

     On June 22, 1999, John Delea, our Chief Financial Officer, exercised an
option to purchase 150,000 shares of common stock. Because the shares were
vested under the terms of the option, he was not required to enter into a stock
restriction and repurchase agreement with us. In addition to the options
exercised as indicated above, Mr. Delea has options to purchase an additional
22,500 shares of common stock, Ms. Estabrook has options to purchase an
additional 86,250 shares of common stock and Mr. George has options to purchase
an additional 52,500 shares of common stock, which each may exercise at any time
upon entering into an appropriate stock restriction and repurchase agreement
with us. In September 1999, Christopher Paul's employment with us terminated,
and in December 1999 we repurchased from him 124,687 shares of common stock
pursuant to his stock restriction and repurchase agreements.

TERMS OF TRANSACTIONS

     We believe that all of the transactions described above were made on terms
no less favorable to us than we would have obtained from unaffiliated third
parties. We have adopted a policy under which all future transactions between us
and any of our directors, executive officers or 5% stockholders must be on terms
no less favorable to us than we would obtain from unaffiliated third parties and
must be approved by a majority of the disinterested members of the board of
directors.

                             PRINCIPAL STOCKHOLDERS

     The following table provides information about the beneficial ownership of
our common stock as of January 26, 2000, by:

     - each person or entity known to own beneficially more than five percent of
       our common stock

     - each of the named executive officers

     - each of our directors

     - all of our executive officers and directors as a group

     In accordance with SEC rules, beneficial ownership includes any shares for
which a person or entity has sole or shared voting power or investment power and
any shares of which the person or entity has the right to acquire beneficial
ownership within 60 days after January 26, 2000 through the exercise of any
option or otherwise. Except as noted below, we believe that the persons named in
the table have sole voting and investment power with respect to the shares of
common stock set forth opposite their names. Percentage of beneficial ownership
is based on 16,123,989 shares of common stock outstanding as of January 26,
2000, including shares into which our outstanding preferred stock will convert
upon completion of this offering, and 20,459,832 shares of common stock that
will be outstanding after completion of this offering, including 85,843 shares
that we expect to issue upon the exercise of a warrant before the completion of
this offering. All shares included in the "Right to Acquire" column represent
shares subject to outstanding stock options exercisable within 60 days after
January 26, 2000. The address of our executive officers and directors is in care
of net.Genesis Corp., 150 CambridgePark Drive, Cambridge, Massachusetts 02140.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     Upon completion of this offering, we will be authorized to issue
100,000,000 shares of common stock, $0.001 par value, and 5,000,000 shares of
undesignated preferred stock, $0.001 par value. The following is a summary
description of our capital stock.

COMMON STOCK

     As of January 26, 2000, there were 16,123,989 shares of common stock
outstanding, assuming the conversion of all outstanding shares of preferred
stock into common stock upon completion of this offering. The shares were held
of record by 156 stockholders.

     Holders of common stock are entitled to one vote per share on all matters
to be voted upon by the stockholders. Holders of common stock are entitled to
receive their proportionate share of dividends, if any, declared from time to
time by the board of directors out of funds legally available for that purpose.
See "Dividend Policy." In the event of our liquidation, dissolution or winding
up, holders of common stock are entitled to their proportionate share of all
assets remaining after payment of liabilities, after taking into consideration
the prior distribution rights of any preferred stock then outstanding. Common
stock has no preemptive or conversion rights or other subscription rights. No
redemption or sinking fund provisions apply to the common stock. All outstanding
shares of common stock are fully paid and nonassessable, and the shares of
common stock being offered by us will be fully paid and nonassessable upon the
completion of this offering.

PREFERRED STOCK


     Immediately prior to this offering, our certificate of incorporation
provided for six series of preferred stock. Upon the completion of this
offering, each outstanding share of preferred stock will automatically convert
into 0.75 shares of common stock. See "Transactions with Related Parties --
Sales of Preferred Stock" for a description of purchases of our preferred stock
by our directors, executive officers and 5% stockholders.


     Upon the completion of this offering, the board of directors will be
authorized, without stockholder approval, to issue from time to time up to
5,000,000 shares of preferred stock in one or more series, each series to have
whatever rights and preferences, including voting rights, dividend rights,
conversion rights, redemption privileges and liquidation preferences, that the
board of directors may determine. The rights of the holders of common stock will
be affected by, and may be adversely affected by, the rights of holders of any
preferred stock that we may issue in the future. The issuance of preferred
stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of making it
more difficult for others to acquire, or of discouraging others from attempting
to acquire, a majority of our outstanding voting stock. We have no current plans
to issue any shares of preferred stock.

WARRANTS

     We have outstanding warrants to purchase 209,804 shares at an exercise
price of $2.45 per share. These warrants will expire three years after
completion of this offering. We also have outstanding a warrant to purchase
85,843 shares at an exercise price of $4.43. This warrant will expire upon the
effective date of this offering. We expect the holder of this warrant to
exercise the warrant before that date.

REGISTRATION RIGHTS

     After the completion of this offering, the holders of approximately
12,259,455 shares of common stock and warrants to purchase 209,804 shares of
common stock, or their permitted transferees, will

                                       65
<PAGE>   70

be entitled to certain rights with respect to registration of their shares, or
"registrable securities," under the Securities Act.

     At any time after 180 days following the effective date of the registration
statement for this offering, the holders of at least 50% of the registrable
securities then outstanding can require us to file a registration statement
covering their registrable securities if the reasonably anticipated aggregate
offering price to the public would exceed $7.5 million. In addition, two years
after this offering, holders of registrable securities may require us to
register their shares for public resale on Form S-3 or any successor form if we
are able to use that form and the reasonably anticipated aggregate offering
price to the public would exceed $1.0 million. Furthermore, if we choose to
register any of our shares of common stock or other securities for any public
offering, the holders of registrable securities are entitled to include their
registrable securities in the registration, subject to the right of the managing
underwriter of the offering to reduce the number of shares to be registered in
view of market conditions. This incidental registration right has been waived
with respect to this offering. We will pay all of the expenses of any
registration, other than underwriting discounts and commissions and
extraordinary expenses attributable to any one security holder. If any person
with registration rights holds less than 1% of our outstanding capital stock,
the person's registration rights terminate when the person becomes entitled to
sell all of its shares in any 90-day period under Rule 144 of the Securities
Act.

     If our stockholders with registration rights cause a large number of
securities to be registered and sold in the public market, those sales could
cause the market price of our common stock to fall. If we were to initiate a
registration and include registrable securities because of the exercise of
registration rights, the inclusion of registrable securities could adversely
affect our ability to raise capital.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF DELAWARE LAW AND OUR CHARTER AND BY-LAWS

     Provisions of Delaware law and our certificate of incorporation and by-laws
could make it more difficult to acquire us by means of a tender offer, a proxy
contest, open market purchases, removal of incumbent directors and otherwise.
These provisions, summarized below, are expected to discourage types of coercive
takeover practices and inadequate takeover bids and to encourage persons seeking
to acquire control of us to first negotiate with us. We believe that the
benefits of increased protection of our potential ability to negotiate with the
proponent of an unfriendly or unsolicited proposal to acquire or restructure us
outweigh the disadvantages of discouraging takeover or acquisition proposals
because negotiation of these proposals could result in an improvement of their
terms.

     We must comply with Section 203 of the Delaware General Corporation Law, an
anti-takeover law. In general, Section 203 prohibits a publicly held Delaware
corporation from engaging in a business combination with an interested
stockholder for a period of three years following the date the person became an
interested stockholder, unless the business combination or the transaction in
which the person became an interested stockholder is approved in a prescribed
manner. Generally, a business combination includes a merger, asset or stock
sale, or other transaction resulting in a financial benefit to an interested
stockholder. An interested stockholder includes a person who, together with
affiliates and associates, owns, or did own within three years before the
determination of interested stockholder status, 15% or more of the corporation's
voting stock. The existence of this provision generally will have an
anti-takeover effect for transactions not approved in advance by the board of
directors, including discouraging attempts that might result in a premium over
the market price for the shares of common stock held by stockholders.

     Upon the completion of this offering, our certificate of incorporation and
by-laws will require that any action required or permitted to be taken by our
stockholders must be effected at a duly called annual or special meeting of the
stockholders and may not be effected by a consent in writing. In addition, upon
the completion of this offering, special meetings of our stockholders may

                                       66
<PAGE>   71

be called only by the board of directors or some of our officers. Our
certificate of incorporation and by-laws also provide that, effective upon the
completion of this offering, our board of directors will be divided into three
classes, with each class serving staggered three-year terms. These provisions
may have the effect of deterring hostile takeovers or delaying changes in our
control or management.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is BankBoston, N.A.

LISTING

     We have applied to list our common stock on the Nasdaq National Market
under the symbol NTGX.

                                       67
<PAGE>   72

                        SHARES ELIGIBLE FOR FUTURE SALE

     Before this offering, there has been no market for our common stock. We
cannot predict the effect, if any, that sales of shares of common stock to the
public or the availability of shares for sale to the public will have on the
market price of the common stock prevailing from time to time. Nevertheless, if
a significant number of shares of common stock are sold in the public market, or
if people believe that such sales may occur, the prevailing market price of our
common stock could decline and could impair our future ability to raise capital
through the sale of our equity securities.

     Giving effect to this offering and the exercise of a warrant, upon
completion of this offering we will have outstanding 20,459,832 shares of common
stock, assuming no exercise of any other outstanding options or warrants after
January 26, 2000. Of these shares, the 4,250,000 shares sold in this offering
will be freely tradable without restriction under the Securities Act except for
any shares purchased by affiliates of net.Genesis, as that term is defined in
Rule 144 under the Securities Act.

     The remaining 16,209,832 shares of common stock were issued and sold by us
in reliance on exemptions from the registration requirements of the Securities
Act and as a result are restricted securities. A total of 16,057,509 shares are
subject to lock-up agreements with the underwriters that provide that the
holders of those shares may not dispose of or hedge any common stock or
securities convertible into or exchangeable for shares of common stock. These
restrictions will be in effect for a period of 180 days after the date of this
prospectus. At any time and without notice, Chase Securities Inc. may, in its
sole discretion, release some or all of the securities from these lock-up
agreements. In addition, holders of stock options and warrants could exercise
these options and warrants and sell the shares issued upon exercise as described
below. The following table describes the number of outstanding shares that will
become eligible for sale in the public market on several relevant dates.

</TABLE>

RULE 144

     In general, under Rule 144, an affiliate of net.Genesis, or any person or
persons whose shares are aggregated, who has beneficially owned restricted
shares for at least one year, generally including the holding period of any
prior owner other than an affiliate from whom the holder acquired the shares for
value, will be entitled to sell in any three-month period a number of shares
that does not exceed the greater of:

     - one percent of the then-outstanding shares of common stock (approximately
       204,598 shares immediately after this offering)

     - the average weekly trading volume during the four calendar weeks before
       the date on which the seller files a notice of the proposed sale with the
       SEC

                                       68
<PAGE>   73

     Sales under Rule 144 must also comply with manner of sale provisions and
notice requirements, and information about us must be publicly available. All
holders of Rule 144 shares are required to wait until 90 days after the date of
this prospectus before selling those shares.

RULE 144(k)

     Under Rule 144(k), a person who has not been an affiliate of net.Genesis at
any time during the three months before a sale, and who has beneficially owned
the shares proposed to be sold for at least two years, generally including the
holding period of any prior owner other than an affiliate from whom the holder
acquired the shares for value, is entitled to sell those shares without
complying with the volume limitation, manner of sale, notice filing or public
information requirements of Rule 144. Therefore, unless otherwise restricted,
shares eligible for sale under Rule 144(k) may be sold immediately upon the
completion of this offering.

RULE 701

     Any of our employees, officers, directors or consultants who purchased
shares pursuant to a written compensatory plan or contract may be entitled to
rely on the resale provision of Rule 701. Rule 701 permits affiliates to sell
their Rule 701 shares under Rule 144 without complying with the holding period
requirements of Rule 144. Rule 701 further provides that non-affiliates may sell
these shares in reliance on Rule 144 without having to comply with the holding
period, public information, volume limitation or notice provisions of Rule 144.
All holders of Rule 701 shares are required to wait until 90 days after the date
of this prospectus before selling those shares.

     We are unable to estimate the number of shares that will be sold under
Rules 144, 144(k) and 701 because that number will depend on the market price
for the common stock, the personal circumstances of the sellers and other
factors. Upon the completion of this offering, we intend to file a registration
statement on Form S-8 under the Securities Act covering, among other things,
shares of common stock covered by outstanding options under our stock plans.
Based on the number of shares covered by outstanding options and reserved for
issuance under our stock plans as of January 26, 2000, the registration
statement would cover approximately 4,321,556 shares. The registration statement
will become effective upon filing. Accordingly, shares registered under the
registration statement on Form S-8 will be available for sale in the open market
immediately, after complying with Rule 144 volume limitations applicable to
affiliates, and with applicable 180-day lock-up agreements.

REGISTRATION RIGHTS

     After the completion of this offering, holders of approximately 12,259,455
shares of common stock and warrants to purchase 209,804 shares of common stock
will be entitled to specific rights to register those shares for sale in the
public market. See "Description of Capital Stock -- Registration Rights."
Registration of these shares under the Securities Act would result in the shares
becoming freely tradable without restriction under the Securities Act, except
for shares purchased by affiliates, immediately upon the effectiveness of the
registration.

</TABLE>

     The underwriting agreement provides that the obligations of the
underwriters are conditioned on the absence of any material adverse change in
our business and the receipt of certificates, opinions and letters from us, our
counsel and our independent auditors. The underwriters are committed to purchase
all shares of common stock offered in this prospectus if any shares are
purchased.

     The underwriters propose to offer the shares of common stock directly to
the public at the public offering price set forth on the cover page of this
prospectus and to dealers at the public offering price less a concession not in
excess of $          per share. The underwriters may allow and the dealers may
reallow a concession not in excess of $          per share to other dealers.
After the public offering of the shares, the underwriters may change the
offering price and other selling terms. The representatives of the underwriters
have informed us that the underwriters do not intend to confirm discretionary
sales in excess of 5% of the shares of common stock offered by this prospectus.

     We have granted to the underwriters an option, exercisable no later than 30
days after the date of this prospectus, to purchase up to 637,500 additional
shares of common stock at the public offering price, less the underwriting
discount set forth on the cover page of this prospectus. To the extent that the
underwriters exercise this option, each underwriter will have a firm commitment
to purchase a number of shares that approximately reflects the same percentage
of total shares the underwriter purchased in the above table. We will be
obligated to sell shares to the underwriters to the extent the option is
exercised. The underwriters may exercise this option only to cover over-
allotments made in connection with the sale of common stock offered in this
prospectus.

     The following table shows the per share and total underwriting discounts
and commissions that we will pay to the underwriters. The underwriting discount
was determined based on an arms' length negotiation between the representatives
of the underwriters and us. These amounts are shown assuming both no exercise
and full exercise of the underwriters' over-allotment option to purchase
additional shares.

     We estimate that our share of the total expenses of the offering, excluding
underwriting discounts and commissions, will be approximately $1,000,000. The
offering of the shares is made for delivery when, as and if accepted by the
underwriters and subject to prior sale and to withdrawal,

                                       70

cancellation or modification of the offering without notice. The underwriters
reserve the right to reject an order for the purchase of shares in whole or in
part.

     We have agreed to indemnify the underwriters against liabilities, including
liabilities under the Securities Act, and to contribute to payments the
underwriters may be required to make in respect of those liabilities.

     Chase Securities Inc. and its affiliates beneficially own an aggregate of
349,360 shares of our common stock. Chase Securities Inc. also holds a warrant
to purchase 85,843 shares of common stock that will expire upon the effective
date of this offering. We expect Chase Securities Inc. to exercise this warrant
before that date.

     Substantially all of our stockholders holding in the aggregate 16,057,509
shares of common stock, and including all of our executive officers and
directors, have agreed that they will not, without the prior written consent of
Chase Securities Inc., offer, sell or otherwise dispose of any shares of common
stock, options or warrants to acquire shares of common stock or securities
exchangeable for or convertible into shares of common stock owned by them during
the 180-day period following the date of this prospectus. We have agreed that we
will not, without the prior written consent of Chase Securities Inc., offer,
sell or otherwise dispose of any shares of common stock, options or warrants to
acquire shares of common stock or securities exchangeable for or convertible
into shares of common stock during the 180-day period following the date of this
prospectus, except that we may issue shares upon the exercise of options granted
prior to the date of this prospectus and may grant additional options under our
stock plans, provided that, without the prior written consent of Chase
Securities Inc., any additional options shall not be exercisable during the
180-day period.

     At our request, the underwriters have reserved up to 340,000 shares of
common stock to be sold in the offering and offered for sale, at the public
offering price, to our directors, officers, employees, business associates such
as customers and suppliers and persons related to, or affiliated with the
foregoing persons. The number of shares available for sale to the general public
in the offering will be reduced to the extent these persons purchase the
reserved shares. Any reserved shares not so purchased will be offered to the
general public on the same basis as other shares offered by this prospectus.

     Persons participating in this offering may over-allot or effect
transactions that stabilize, maintain or otherwise affect the market price of
the common stock at levels above those that might otherwise prevail in the open
market, including by entering stabilizing bids, effecting syndicate covering
transactions or imposing penalty bids. A stabilizing bid means the placing of
any bid or the effecting of any purchase for the purpose of pegging, fixing or
maintaining the price of the common stock. A syndicate covering transaction
means the placing of any bid on behalf of the underwriting syndicate or the
effecting of any purchase to reduce a short position created in connection with
the offering. A penalty bid means an arrangement that permits the underwriters
to reclaim a selling concession from a syndicate member in connection with the
offering when shares of common stock sold by the syndicate member are purchased
in syndicate covering transactions. These transactions may be effected on the
Nasdaq National Market, in the over-the-counter market or otherwise.
Stabilizing, if commenced, may be discontinued at any time.

     Before this offering, there was no public market for the common stock. The
initial public offering price for the common stock will be determined by
negotiations between ourselves and the representatives. Among the factors to be
considered in determining the initial public offering price will be prevailing
market and economic conditions, our revenues and earnings, market valuations of
other companies engaged in activities similar to ours, estimates of our business
potential and prospects, the present state of our business operations, our
management and other factors deemed relevant.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
of net.Genesis Corp.


In our opinion, the accompanying balance sheets and the related statements of
operations, of changes in stockholders' equity (deficit) and of cash flows
present fairly, in all material respects, the financial position of net.Genesis
Corp. at December 31, 1998 and 1999, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1999 in
conformity with accounting principles generally accepted in the United States.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS

1. NATURE OF THE BUSINESS AND BASIS OF FINANCIAL STATEMENTS

     net.Genesis provides software and professional services that help its
customers understand, analyze and improve their online businesses. Its
net.Analysis software enables companies to collect, store, organize and analyze
detailed information about the online behavior of customers and other visitors
on their web sites. The Company operates in one business segment and its
principal markets are the domestic and international business markets. In
addition, the Company provides consulting, training, maintenance and support
services to facilitate the installation and use of its software.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Significant accounting policies followed in the preparation of the
financial statements are as follows:

  Pro Forma Balance Sheet (Unaudited)

     Upon the closing of the Company's initial public offering, all of the
outstanding shares of Series A, B, C, D, and F convertible preferred stock will
automatically convert on a .75-for-1 basis to approximately 12,867,683 shares of
the Company's common stock assuming an offering price of greater than $8.85 per
share. The unaudited pro forma presentation of the balance sheet has been
prepared assuming the conversion of the convertible preferred stock into common
stock as of December 31, 1999.

  Use of Estimates

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

  Cash Equivalents, Short-term Investments and Marketable Securities

     The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. The Company invests its
excess cash primarily in a money market account which is managed by a financial
institution with a strong credit rating. Accordingly, these investments are
subject to minimal credit and market risk and are classified as
available-for-sale. At December 31, 1998 and 1999, the Company's cash
equivalents consisted of certificates of deposit and money market funds totaling
approximately $1,860,000 and $8,754,487, respectively. The carrying amount in
the financial statements approximates fair value because of the short maturity
and holding period of these instruments. At December 31, 1999, all of the
Company's short-term investments and marketable securities consist of common
stock recorded at fair value and classified as available for sale. Realized
gains and losses on sales of securities for the years ended December 31, 1997,
1998, and 1999 were not significant.

     Restricted Cash

     Restricted cash represents a deposit held at a major financial institution
as collateral for letters of credit that secure the Company's payroll liability,
office lease and leases of certain of the Company's fixed assets.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     Revenue Recognition

     SOP No. 97-2, as amended, was adopted by the Company in the fiscal year
beginning January 1, 1998. The Company generates several types of revenue,
including the following:

          License Fees

     The Company's standard end user license agreement for the Company's
products provides for an initial fee to use the product in perpetuity up to a
maximum number of users. The Company also enters into other license agreement
types, typically with major end user customers, which allow for the use of the
Company's products, usually restricted by the number of employees, the number of
users, number of servers or the license term. Fees from licenses are recognized
as revenue when a contract has been executed and the product has been delivered,
provided fees are fixed or determinable, collection is probable and there are no
uncertainties with respect to customer acceptance. If uncertainties exist,
revenue is deferred until such time as the customer accepts the product or
service. Revenue under arrangements where multiple products or services are sold
together under one contract is allocated to each element based on their relative
fair values, with these fair values being determined using the price charged
when that element is sold separately. License fees from software sold together
with services are generally recognized upon delivery of the software provided
that the above criteria have been met and the services are not essential to the
functionality of the software. In instances where the aforementioned criteria
have not been met, both the license and professional services fees are
recognized under the percentage of completion method of contract accounting,
based upon the proportion of hours expended to total estimated hours at
completion. Losses, if any, on fixed price contracts are recognized when the
loss is determined.

          Service and Support Agreements

     The Company provides consulting, installation and training services to its
customers. Revenue from such services is generally recognized over the period
during which the applicable service is to be performed or on a
services-performed basis. Support agreements generally call for the Company to
provide technical support and software updates to customers. Revenue for support
agreements is recognized ratably over the term of the support agreement and is
included in services revenue in the accompanying statements of operations.

     Fair Value of Financial Instruments

     The carrying amounts of the Company's financial instruments, which include
cash equivalents, short-term investments and marketable securities, accounts
receivable, accounts payable, accrued expenses, capital lease obligations and
debt, approximate their fair values at December 31, 1998 and 1999.

 Concentrations of Credit Risk, Significant Customers and Revenue by Geographic
 Region

     Financial instruments which potentially expose the Company to
concentrations of credit risk include accounts receivable. The Company performs
ongoing evaluations of customers' financial condition and does not generally
require collateral. The Company maintains reserves for potential credit losses,
which in the aggregate, have not exceeded management's expectations.

     At December 31, 1998, accounts receivable from one customer accounted for
approximately 13% of total accounts receivable. At December 31, 1999, accounts
receivable from one customer accounted for approximately 11% of total accounts
receivable.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     During the year ended December 31, 1998, revenue from each of two customers
accounted for approximately 11% of total revenue. During the years ended
December 31, 1997 and 1999, no customer accounted for more than 10% of total
revenue.

     The Company markets its products and related services to customers in many
industries, principally in the United States, Europe and Australia. Revenue by
geographic region is as follows:

</TABLE>

  Fixed Assets

     Fixed assets are recorded at cost and depreciated using the straight-line
method over the estimated useful lives of the assets. Capital leases and
leasehold improvements are amortized over the lease life or the estimated useful
life of the asset. Upon retirement or sale, the costs of the assets disposed and
the related accumulated depreciation are removed from the accounts and any
resulting gain or loss is included in the determination of income. Maintenance
and repair costs are charged to expense as incurred. Estimated useful lives
generally range from three to five years.

  Research and Development and Software Development Costs

     Costs incurred in the research and development of the Company's products
are expensed as incurred. Software development costs incurred subsequent to the
establishment of technological feasibility are capitalized in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting for the
Cost of Computer Software to be Sold, Leased or Otherwise Marketed." No software
development costs were capitalized during 1997, 1998 or 1999 since costs
incurred subsequent to the establishment of technological feasibility were not
significant.

  Advertising Expense

     The Company recognizes advertising expense as incurred. Advertising expense
was approximately $93,000, $49,000 and $130,720 for the years ended December 31,
1997, 1998, and 1999, respectively.

  Accounting for Stock-Based Compensation

     The Company accounts for stock-based awards to employees using the
intrinsic value method as prescribed by Accounting Principles Board Opinion
("APB") No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. The Company has adopted the provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation," through disclosure only (Note 8).

 Net Loss per Share and Unaudited Pro Forma Net Loss Per Share

     Basic and diluted net loss available to common stockholders per share is
computed by dividing loss available to common stockholders by the weighted
average number of shares of common stock outstanding during the period,
excluding shares of common stock subject to repurchase. Diluted net

                                       F-9

                               net.GENESIS CORP.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

loss available to common stockholders per share does not differ from basic net
loss per share since potential common shares from conversion of preferred stock
and exercise of stock options and warrants are anti-dilutive for all periods
presented. Unaudited pro forma basic and diluted net loss available to common
stockholders per share have been calculated assuming the conversion of all
outstanding shares of preferred stock into common shares, as if the shares had
converted immediately upon their issuance.

  Recently Enacted Accounting Standards

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument be recorded in
the balance sheet as either an asset or liability measured at its fair value.
SFAS No. 133, as recently amended, is effective for fiscal years beginning after
June 15, 2000. Because the Company does not currently hold any derivative
instruments and does not currently engage in hedging activities, the Company
expects that adoption of SFAS No. 133 will not have a material impact on its
financial position or operating results.

3. ACCOUNTS RECEIVABLE

     Provisions for doubtful accounts charged to the statement of operations
were $3,992, $42,215 and $307,340 in 1997, 1998 and 1999, respectively, and
write-offs against the allowances were $14,774, $0 and $0 in 1997, 1998 and
1999, respectively.

5. CAPITAL LEASE AND BORROWINGS

     In January 1999, the Company entered into an agreement with a leasing
company to establish a line of credit that enabled the Company to finance up to
$1,000,000 in purchases of property and equipment under capital leases (the
"lease line"). Each borrowing under the lease line is payable in equal monthly
installments over a period of 36 months and bears interest at a rate of 9% per
annum. In connection with this agreement, the Company granted warrants to
purchase 35,307 shares of the Company's Series E preferred stock at an exercise
price equal to $1.84 per share. These warrants are exercisable immediately and
expire five years from the grant date, or three years from the effective date of
an initial public offering, whichever is earlier. The value ascribed by
management to these warrants was $32,235 and was computed using the
Black-Scholes model with the following assumptions: Series E redeemable
convertible preferred stock fair value of $1.84 per share; warrant exercise
price of $1.84 per share; dividend yield of 0%; risk-free interest rate of

                                      F-10

5.02%; expected term of 5 years (life of the warrants); and 50% volatility.
There is $411,168 outstanding on the lease line at December 31, 1999. The future
minimum lease payments as of December 31, 1999 are $475,885.

     During 1999, the Company sold and immediately leased back certain equipment
under the lease line. Total computer equipment of $443,507 was purchased under
the lease line. Amortization of property and equipment under the lease line
totaled $84,723 during the year ended December 31, 1999 and is included in
depreciation expense. Interest expense relating to the lease line totaled
$24,629 for the year ended December 31, 1999.

     In January 1999, the Company entered into a subordinated debt agreement
providing for borrowings of up to $4,000,000. The subordinated debt is payable
in 36 monthly payments and bears interest at a rate of 13.5%. At December 31,
1999, the Company had $2,904,292 outstanding under the agreement.

     In connection with the subordinated debt, the Company granted warrants to
purchase 244,432 shares of the Company's Series E redeemable convertible
preferred stock at an exercise price equal to $1.84 per share. These warrants
are exercisable immediately and expire five years from the grant date, or three
years from the effective date of an initial public offering, whichever is
earlier. The value ascribed by management to these warrants was $223,167 and was
computed using the Black-Scholes model with the following assumptions: Series E
redeemable convertible preferred stock fair value of $1.84 per share; warrant
exercise price of $1.84 per share; dividend yield of 0%; risk free interest rate
of 5.02%; expected term of 5 years (life of the warrants); and 50% volatility.
The warrant value was recorded as a debt discount and is being amortized to
interest expense over the term of the loans.

     The subordinated debt and the lease line are secured by substantially all
assets of the Company. Under these agreements, the Company is required to comply
with certain covenants. The Company is in compliance with these covenants for
all periods presented.

     In February 1996, the Company entered into a Credit Agreement for an
equipment term loan providing for eligible borrowings of up to $250,000.
Eligible borrowings under the term loan were based on accounts receivable and
other assets and determined according to a formula defined in the Credit
Agreement. At December 31, 1998 and 1999, the Company had $9,083 and $0,

  Conversion

     Each share of the Series A, Series B, Series C, Series D, Series E and
Series F Preferred Stock is convertible at any time at the option of the holder
into shares of common stock at a ratio of .75 shares of common stock for each
share of Preferred Stock, subject to certain anti-dilution adjustments. In
addition, the conversion ratio is subject to adjustment, as defined in the
agreement, in the event that the Company issues common stock or preferred stock
at a per share price less than the original purchase prices for all series of
Preferred Stock.

     The Series A, Series B, Series C, Series D, Series E and Series F Preferred
Stock will automatically convert to common stock immediately prior to the
closing of a public offering of the Company's common stock resulting in gross
proceeds of at least $20,000,000 based on an offering price per share of not
less than $8.85.

  Dividends

     Dividends on the Series A Preferred Stock are payable when and if declared
by the Board of Directors. Through December 31, 1999, no dividends have been
declared or paid by the Company.

     The holders of Series B, Series C, Series D, Series E and Series F
Preferred Stock are entitled to receive cumulative dividends at an annual rate
of 7% of the original purchase price. Dividends are payable whether or not
declared. Cumulative and unpaid dividends on Series B, Series C, Series D,
Series E and Series F Preferred Stock were $921,665, $235,468, $743,400, $0 and
$898,333 at December 31, 1999, respectively.

  Liquidation Preference

     In the event of any liquidation, dissolution or winding up of the affairs
of the Company, the holders of the Series B, Series C, Series D, Series E and
Series F Preferred Stock are entitled to receive on a pro rata basis, prior and
in preference to the holders of other preferred or common stock, $5.15 per
share, $.50 per share, $1.20 per share, $1.84 per share and $3.32 per share,
respectively, plus all accrued and unpaid dividends.

     The holders of Series A-1 Preferred Stock, Series A-2 Preferred Stock and
Series A-3 Preferred Stock will be entitled to receive in preference to the
holders of the common stock an amount equal to $.25, $1.38 and $2.50,
respectively, plus any accrued but unpaid dividends.

  Voting Rights

     Each holder of the Series A, Series B, Series C, Series D, Series E and
Series F Preferred Stock is entitled to the number of votes equal to the number
of shares of common stock into which such holder's shares are convertible at the
record date for such vote.

     Holders of the Series B, Series C, Series D, Series E and Series F
Preferred Stock are also entitled to vote together as a separate class to
approve or reject certain transactions, including mergers and certain changes to
equity.

8. COMMON STOCK

     Each share of common stock entitles the holder to one vote on all matters
submitted to a vote of the Company's stockholders. Common stockholders are
entitled to receive dividends, if any, as may be declared by the Board of
Directors, subject to any preferential dividend rights of the preferred
stockholders.

     In October 1997, the Board of Directors authorized a 1-for-5 reverse stock
split of the Company's common stock. All common share and per share amounts
included in the accompanying financial statements and notes thereto have been
adjusted to reflect the reverse stock split.

     In June 1998, the Company increased the number of authorized shares of
common stock from 11,697,872 to 17,500,000 shares.

     In June 1999, the Company increased the number of authorized shares of
common stock from 17,500,000 to 24,000,000 shares.

     In December 1999, the Company increased the number of authorized shares of
common stock from 24,000,000 to 100,000,000 shares.

     In January 2000, the Company authorized a 3-for-4 reverse split of its
common stock. As a result, all references to common stock share and per share
amounts, including options and warrants to purchase common stock, have been
retroactively restated to reflect the reverse split.

     The Company has reserved 14,564,294 shares of common stock for the
conversion of the Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock and for the exercise of outstanding options at December 31,
1999.

  Stock Restriction Agreements

     The Company has entered into stock restriction agreements with certain
common stockholders. The agreements provide that in the event that any
individual who is a party to such agreement is no longer employed by the
Company, the Company may repurchase all shares that are not vested

                                      F-14

at the time the individual ceases to be employed by the Company. These shares
generally vest over four years, as defined in the agreements. At December 31,
1998 and 1999, approximately 719,534 and 1,267,626 shares of common stock,
respectively, are subject to repurchase.

9. STOCK OPTIONS

     The 1995 Incentive Stock Option Plan (the "Plan") provides for the grant of
incentive stock options and nonqualified stock options. The Board of Directors
is responsible for administration of the Plan. The Board of Directors determines
the term of each option, option exercise price, number of shares for which each
option is granted and the rate at which each option is exercisable. Options
generally vest ratably over four years. Options granted under the Plan generally
expire ten years from the date of the grant.

     Nonqualified stock options may be granted to any officer, employee,
director or consultant at an exercise price per share as determined by the
Company's Board of Directors.

     In July 1998, the Company increased the number of options available for
grant under the Plan to 3,000,000.

     In September 1999, the Company increased the number of options available
for grant under the Plan from 3,000,000 to 3,750,000.

     Transactions under the 1995 Stock Option Plan for the years ended December
31, 1997, 1998, and 1999 are summarized as follows:

     As of December 31, 1997, 1998 and 1999, 41,448, 320,638 and 170,525 options
were exercisable, respectively, under the Plan. The weighted average fair value
of options granted, all with exercise prices equal to the fair market value of
the Company's common stock at the date of grant, during 1997 and 1998 was $.11
and $.04, respectively. The weighted average fair value of options granted, all
with exercise prices below the fair market value of the Company's common stock
at the date of grant, was $4.92 during 1999.

     During 1997, the Company's Board of Directors determined that, because
certain stock options held by employees of the Company had an exercise price
significantly higher than the fair value of

the Company's common stock, such stock options were not providing the incentive
intended. Accordingly, in September 1997, options to purchase 351,165 shares of
common stock with an exercise price of $1.87 per share were canceled and
reissued at a price of $.07 per share. The exercise price of the repriced
options equaled the fair market value of the Company's common stock on the date
of repricing.

     During the year ended December 31, 1999, the Company issued options to
certain employees under the Plan with exercise prices below the amount
subsequently determined to be the fair market value of the common stock at the
date of grant for financial reporting purposes. In accordance with the
requirements of APB 25, the Company has recorded deferred compensation for the
differences between the exercise price of the options and the deemed fair market
value of the Company's stock at the date of grant. This deferred compensation is
amortized to expense over the vesting periods, generally four years.

     As discussed in Note 2, the Company has adopted SFAS 123 through disclosure
only. Had compensation cost for the Company's option plan been determined based
on the fair value of the options at the grant dates, as prescribed in SFAS 123,
the Company's net loss and basic and diluted net loss per share on a pro forma
basis would have been as follows:

     The fair value of each option grant is estimated on the date of grant using
the minimum value method with the following assumptions used for grants during
the applicable period:

     Because the determination of the fair value of all options granted after
the Company becomes a public entity will include an expected volatility factor
in addition to the factors noted above, and because additional option grants are
expected to be made and options vest over several years, the above pro forma
disclosures are not representative of the pro forma effects on reported net
income or loss for future years.

  1999 Stock Incentive Plan

     In December 1999, the Company adopted its 1999 stock incentive plan and
reserved 2,625,000 shares of common stock for issuance under the plan. As of
December 31, 1999, no options or other awards had been granted under the 1999
plan. The 1999 plan authorizes the grant of incentive options and nonqualified
options and also provides for awards of stock appreciation rights, performance
shares, restricted stock and other stock-based awards.

     Incentive options may be granted under the 1999 plan to key employees of
the Company and its affiliates within the meaning of the Internal Revenue Code,
including officers and directors as well as officers and directors of the
Company's affiliates who are also employees. The exercise price of incentive
options granted under the 1999 plan must be at least equal to the fair market
value of the common stock on the date of grant. The exercise price of incentive
options granted to an optionee who owns stock possessing more than 10% of the
voting power of our outstanding capital stock must be at least equal to 110% of
the fair market value of the common stock on the date of grant, and such
optionee must exercise his or her option within five years from the date of the
grant of such option.

     Additionally, the Company may grant nonqualified options to its officers
and other employees, directors, and other individuals providing services to the
Company. There are no limits on the exercise price of nonqualified options
granted under the 1999 plan.

     The 1999 plan is administered by the compensation committee of the board of
directors. The compensation committee selects the individuals to whom options
will be granted and determines the option exercise price and other terms of each
award, subject to the provisions of the 1999 plan.

  1999 Employee Stock Purchase Plan

     In December 1999, the Company adopted its 1999 employee stock purchase plan
and reserved 225,000 shares of common stock for issuance under the plan.

     Under the terms of the stock purchase plan, all employees who have
completed three months of employment and whose customary employment is more than
20 hours per week and more than five months in the calendar year are eligible to
participate in the stock purchase plan. Employees who own stock and hold
outstanding options to purchase stock representing five percent or more of the
total combined voting power or value of all classes of the Company's stock are
not eligible to participate in the stock purchase plan.

     At the commencement of each designated payroll deduction period, or
offering period, an eligible employee may authorize the Company to deduct
between 1% to 10%, in increments of 1%, of his or her base pay. On the last
business day of the offering period, the Company will deem the employee to have
exercised the option, at the exercise option price, to the extent of accumulated
payroll deductions. The purchase price will be 85% of the closing market price
of the common stock on either (a) the first business day of the offering period
or (b) the last business day of the offering period, whichever is lower.

     As of December 31, 1999 no stock has been issued under the plan.

10. INCOME TAXES

     Deferred tax assets consist of the following:

                                             ===========    ===========    ============
</TABLE>

     The Company has provided a full valuation allowance for the deferred tax
assets since it is more likely than not that these future benefits will not be
realized. If the Company achieves future profitability, a significant portion of
these deferred tax assets could be available to offset future income taxes.

     At December 31, 1999, the Company has federal and state net operating loss
and research and development tax credit carryforwards of approximately
$25,541,000 and $586,000, respectively, available to reduce future federal and
state income taxes payable. These net operating loss carryforwards and credits
expire through 2019.

     Certain substantial changes in the Company's ownership occurred during 1997
and 1996. As a result, under the provisions of Section 382 of the Internal
Revenue Code, the amount of net operating loss carryforwards available annually
to offset future taxable income may be limited. The amount of this annual
limitation is determined based upon the Company's value prior to the ownership
changes taking place. Subsequent significant ownership changes could further
affect the limitation in future years.

</TABLE>

     Future minimum lease payments under operating leases have not been reduced
for future sublease rental income of approximately $768,000.

     Rental expense under operating leases for the years ended December 31,
1997, 1998 and 1999 was $200,966, $268,681 and $658,278, respectively.

     The Company is from time to time subject to legal proceedings and claims
which arise in the normal course of its business. In the opinion of management,
the amount of ultimate liability with respect to these actions will not have a
material adverse affect on the Company's financial position or results of
operations.

  Royalty Agreements

     The Company maintains several agreements under which the Company has
obtained the right to use technology related to certain software developed by
others. In exchange, the Company is required to pay royalties as a fixed
percentage of software sales as stipulated in the royalty agreements. Royalty
expense of approximately $34,500, $149,500 and $120,800 was incurred for the
years ended December 31, 1997, 1998 and 1999, respectively.

but were not included in the computations of diluted earnings per share as the
inclusion of these shares would have been anti-dilutive.

13. 401(k) PLAN

     In January 1997, the Company adopted an employee savings and retirement
plan which covers all employees and is qualified under Section 401 of the
Internal Revenue Code. Employees may elect to make voluntary contributions to
the 401(k) plan, based on a percentage of their pretax earnings, up to the
statutorily prescribed annual limit. The Company may make matching or additional
contributions to the 401(k) plan in amounts determined annually by the Board of
Directors. Through December 31, 1999, the Company has made no contributions to
the 401(k) plan.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law authorizes a Delaware
corporation to indemnify its present and former directors and officers under
certain conditions. Article Seventh of our certificate of incorporation provides
that we shall indemnify each person who at any time is, or shall have been, one
of our directors or officers and was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact
that he or she is or was one of our directors or officers, or is or was serving
at our request as a director, officer, trustee of, or in similar capacity with,
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement incurred in connection with any such action, suit or proceeding,
to the maximum extent permitted by the Delaware General Corporation Law, as
currently in effect or amended in the future. No amendment to or repeal of the
provisions of Article Seventh of our certificate of incorporation shall deprive
a director or officer of the benefit of those Articles with respect to any act
or failure occurring prior to such amendment or repeal.

     Section 102(b)(7) of the Delaware General Corporation Law authorizes a
Delaware corporation to adopt a charter provision eliminating or limiting the
personal liability of directors to the corporation or its stockholders for
breach of fiduciary duty as directors, provided that the provision may not
eliminate or limit the liability of directors for:

     - any breach of the director's duty of loyalty to the corporation or its
       stockholders

     - any acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law

     - any payment of a dividend or approval of a stock purchase that is illegal
       under Section 174 of the Delaware General Corporation Law

     - any transaction from which the director derived an improper personal
       benefit

     Article Ninth of our certificate of incorporation provides that, to the
maximum extent permitted by the Delaware General Corporation Law, none of our
directors shall be personally liable to us or to any of our stockholders for
monetary damages arising out of that director's breach

                                      II-1
<PAGE>   100

of fiduciary duty as one of our directors. No amendment to or repeal of the
provisions of Article Ninth shall apply to or have any effect on the liability
or the alleged liability of any of our directors with respect to any act or
failure to act of that director occurring before the amendment or repeal. A
principal effect of Article Ninth is to limit or eliminate the potential
liability of our directors for monetary damages arising from breaches of their
duty of care, unless the breach involves one of the four exceptions described
above.

     Section 145 of the Delaware General Corporation Law also authorizes a
Delaware corporation to obtain insurance on behalf of its directors and officers
against liabilities incurred by them in those capacities. We have procured a
directors' and officers' liability and company reimbursement liability insurance
policy that insures (a) our directors and officers against losses, above a
deductible amount, arising from specified types of claims made against them by
reason of enumerated acts done or attempted by our directors or officers and (b)
us against losses, above a deductible amount, arising from any of the specified
types of claims, but only if we are required or permitted to indemnify our
directors or officers for those losses under statutory or common law or under
provisions of our certificate of incorporation or by-laws.

     The preceding discussion gives effect to amendments of our certificate of
incorporation and by-laws that will become effective upon completion of the
offering contemplated by this Registration Statement.

     Please also see section 7 of the underwriting agreement relating to the
offering, to be filed as Exhibit 1.1 to this Registration Statement, for
indemnification arrangements between us and the underwriters.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

     Since January 26, 1997, we have issued and sold unregistered securities as
described below.

     From January 26, 1997 through the date of this registration statement, we
issued options to purchase a total of 5,582,545 shares of our common stock to
our employees and options to purchase 37,500 shares of our common stock to our
directors and consultants.

     From January 26, 1997 through the date of this registration statement, we
issued and sold an aggregate of 2,052,320 shares of common stock to our
employees, directors and consultants upon exercise of options previously granted
to them, at per share prices ranging from approximately $0.07 to $0.16. We
realized aggregate proceeds of $290,429 from these sales.

     On May 28, 1998, we issued and sold 776,250 shares of common stock to our
President and Chief Executive Officer, Lawrence S. Bohn, for proceeds of
$51,750, or approximately $0.07 per share.

     On September 12, 1997, we sold 2,928,316 shares of series C convertible
preferred stock to 36 accredited investors for proceeds of $1,464,158, or $.50
per share.

     In June and August 1998, we sold a total of 5,899,999 shares of series D
convertible preferred stock to 30 accredited investors for proceeds of
$7,080,000, or $1.20 per share.

     In January 1999, we issued to Comdisco, Inc., an accredited investor, two
warrants to purchase shares of Series E convertible preferred stock at an
aggregate exercise price of $515,000. At the time of issuance, the price and
number of shares subject to the warrant were determined by formula. In June
1999, the warrant was determined to be exercisable for 279,739 shares of Series
E convertible preferred stock at an exercise price of $1.84 per share.

     In June 1999, we sold 6,626,508 shares of series F convertible preferred
stock to 41 accredited investors for proceeds of $22,000,007, or $3.32 per
share. Chase Securities Inc. acted as our placement agent for this offering. In
consideration for their services, we paid Chase Securities Inc.

                                      II-2
<PAGE>   101

$1,158,756 and issued to them a warrant to purchase up to 114,458 shares of our
series F convertible preferred stock at an exercise price of $3.32 per share.

     Each of the sales described above was completed without registration under
the Securities Act in reliance upon one or more of the following exemptions:

     - Section 4(2) of the Securities Act or Rule 506 of Regulation D
       promulgated under the Securities Act for transactions not involving a
       public offering or

     - Rule 701 promulgated under the Securities Act with respect to certain of
       the options and shares of common stock issued to our employees, directors
       and consultants

     None of the sales of the securities we issued have involved the use of an
underwriter, and except for the Series F offering described above, no
commissions were paid in connection with the sale of any of the securities we
issued.

ITEM 17.  UNDERTAKINGS.

     We undertake to provide to the underwriters at the closing specified in the
underwriting agreement, certificates in denominations and registered in names as
required by the underwriters to permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to our directors, officers and controlling persons pursuant to
the foregoing provisions, or otherwise, we have been advised that in the opinion
of the SEC that indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against those liabilities (other than our payment of expenses
incurred or paid by one of our directors, officers or controlling persons of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by our directors, officers or controlling persons in connection with
the securities being registered, we will, unless in the opinion of our counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether that indemnification by us is
against public policy as expressed in the Securities Act and we will be governed
by the final adjudication of such issue.

     We undertake that:

          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus we filed pursuant to Rule 424(b)(1) or (4) or 497(h)
     under the Securities Act shall be deemed to be part of this registration
     statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of those securities at that time shall be
     deemed to be the initial bona fide offering thereof.

     (a) On the basis of the representations and warranties and subject to the
terms and conditions herein set forth, the Company agrees to issue and sell
4,250,000 shares of the Underwritten Stock to the several Underwriters and each
of the Underwriters agrees to purchase from the Company the respective aggregate
number of shares of Underwritten Stock set forth opposite its name in Schedule
I. The price at which such shares of Underwritten Stock shall be sold by the
Company and purchased by the several Underwriters shall be $___ per share. In
making this Agreement, each Underwriter is contracting severally and not
jointly; except as provided in paragraphs (b) and (c) of this Section 3, the
agreement of each Underwriter is to purchase only the respective number of
shares of the Underwritten Stock specified in Schedule I.

     (b) If for any reason one or more of the Underwriters shall fail or refuse
(otherwise than for a reason sufficient to justify the termination of this
Agreement under the provisions of Section 8 or 9 hereof) to purchase and pay for
the number of shares of the Stock agreed to be purchased by such Underwriter or
Underwriters, the Company shall immediately give notice thereof to you, and the
non-defaulting Underwriters shall have the right within 24 hours after the
receipt by you of such notice to purchase, or procure one or more other
Underwriters to purchase,

                                       7

<PAGE>   8

in such proportions as may be agreed upon between you and such purchasing
Underwriter or Underwriters and upon the terms herein set forth, all or any part
of the shares of the Stock which such defaulting Underwriter or Underwriters
agreed to purchase. If the non-defaulting Underwriters fail so to make such
arrangements with respect to all such shares and portion, the number of shares
of the Stock which each non-defaulting Underwriter is otherwise obligated to
purchase under this Agreement shall be automatically increased on a pro rata
basis to absorb the remaining shares and portion which the defaulting
Underwriter or Underwriters agreed to purchase; provided, however, that the
non-defaulting Underwriters shall not be obligated to purchase the shares and
portion which the defaulting Underwriter or Underwriters agreed to purchase if
the aggregate number of such shares of the Stock exceeds 10% of the total number
of shares of the Stock which all Underwriters agreed to purchase hereunder. If
the total number of shares of the Stock which the defaulting Underwriter or
Underwriters agreed to purchase shall not be purchased or absorbed in accordance
with the two preceding sentences, the Company shall have the right, within 24
hours next succeeding the 24-hour period above referred to, to make arrangements
with other underwriters or purchasers satisfactory to you for purchase of such
shares and portion on the terms herein set forth. In any such case, either you
or the Company shall have the right to postpone the Closing Date determined as
provided in Section 5 hereof for not more than seven business days after the
date originally fixed as the Closing Date pursuant to said Section 5 in order
that any necessary changes in the Registration Statement, the Prospectus or any
other documents or arrangements may be made. If neither the non-defaulting
Underwriters nor the Company shall make arrangements within the 24-hour periods
stated above for the purchase of all the shares of the Stock which the
defaulting Underwriter or Underwriters agreed to purchase hereunder, this
Agreement shall be terminated without further act or deed and without any
liability on the part of the Company to any non-defaulting Underwriter and
without any liability on the part of any non-defaulting Underwriter to the
Company. Nothing in this paragraph (b), and no action taken hereunder, shall
relieve any defaulting Underwriter from liability in respect of any default of
such Underwriter under this Agreement.

     (c) On the basis of the representations, warranties and covenants herein
contained, and subject to the terms and conditions herein set forth, the Company
grants an option to the several Underwriters to purchase, severally and not
jointly, up to 637,500 shares in the aggregate of the Option Stock from the
Company at the same price per share as the Underwriters shall pay for the
Underwritten Stock. Said option may be exercised only to cover over-allotments
in the sale of the Underwritten Stock by the Underwriters and may be exercised
in whole or in part at any time (but not more than once) on or before the
thirtieth day after the date of this Agreement upon written or telegraphic
notice by you to the Company setting forth the aggregate number of shares of the
Option Stock as to which the several Underwriters are exercising the option.
Delivery of certificates for the shares of Option Stock, and payment therefor,
shall be made as provided in Section 5 hereof. The number of shares of the
Option Stock to be purchased by each Underwriter shall be the same percentage of
the total number of shares of the Option Stock to be purchased by the several
Underwriters as such Underwriter is purchasing of the Underwritten Stock, as
adjusted by you in such manner as you deem advisable to avoid fractional shares.

Underwriters, may (but shall not be obligated to) make payment to the Company
for shares to be purchased by any Underwriter whose check shall not have been
received by you on the Closing Date or any later date on which Option Stock is

     (c) The Company will (i) on or before the Closing Date, deliver to you four
signed copies of the Registration Statement as originally filed and of each

misleading in the light of the circumstances existing at the time it is
delivered to a purchaser of the Stock, the Company will forthwith prepare and
file with the Commission a supplement to the Prospectus or an amended prospectus
so that the Prospectus as so supplemented or amended will not contain any untrue

at the time such Prospectus is delivered to such purchaser, not misleading. If,
after the initial public offering of the Stock by the Underwriters and during
such period, the Underwriters shall propose to vary the terms of offering
thereof by reason of changes in general market conditions or otherwise, you will
advise the Company in writing of the proposed variation, and, if in the opinion
either of counsel for the Company or of counsel for the Underwriters such
proposed variation requires that the Prospectus be supplemented or amended, the
Company will forthwith prepare and file with the Commission a supplement to the
Prospectus or an amended prospectus setting forth such variation. The Company
authorizes the Underwriters and all dealers to whom any of the Stock may be sold
by the several Underwriters to use the Prospectus, as from time to time amended
or supplemented, in connection with the sale of the Stock in accordance with the
applicable provisions of the Securities Act and the applicable rules and
regulations thereunder for such period.

     (e) Prior to the filing thereof with the Commission, the Company will
submit to you, for your information, a copy of any post-effective amendment to
the Registration Statement and any supplement to the Prospectus or any amended
prospectus proposed to be filed.

     (f) The Company will cooperate, when and as requested by you, in the
qualification of the Stock for offer and sale under the securities or blue sky
laws of such jurisdictions as you may designate and, during the period in which
a prospectus is required by law to be delivered by an Underwriter or dealer, in
keeping such qualifications in good standing under said securities or blue sky
laws; provided, however, that the Company shall not be obligated to file any
general consent to service of process or to qualify as a foreign corporation in
any jurisdiction in which it is not so qualified. The Company will, from time to
time, prepare and file such statements, reports, and other documents as are or
may be required to continue such qualifications in effect for so long a period
as you may reasonably request for distribution of the Stock.

     (g) During a period of five years commencing with the date hereof, the
Company will furnish to you, and to each Underwriter who may so request in
writing, copies of all periodic and special reports furnished to shareholders of
the Company and of all information, documents and reports filed with the
Commission.

     (h) Not later than the 45th day following the end of the fiscal quarter
first occurring after the first anniversary of the Effective Date, the Company
will make generally available to its security holders an earnings statement in
accordance with Section 11(a) of the Securities Act and Rule 158 thereunder.

     (i) The Company agrees to pay all costs and expenses incident to the
performance of its obligations under this Agreement, including all costs and
expenses incident to (i) the preparation, printing and filing with the
Commission and the National Association of Securities Dealers, Inc. of the
Registration Statement, any Preliminary Prospectus and the Prospectus, (ii) the
furnishing to the Underwriters of copies of any Preliminary Prospectus and of
the several

                                       11

<PAGE>   12

documents required by paragraph (c) of this Section 6 to be so furnished, (iii)
the printing of this Agreement and related documents delivered to the
Underwriters, (iv) the preparation, printing and filing of all supplements and
amendments to the Prospectus referred to in paragraph (d) of this Section 6, (v)
the furnishing to you and the Underwriters of the reports and information
referred to in paragraph (g) of this Section 6 and (vi) the printing and
issuance of stock certificates, including the transfer agent's fees.

     (j) The Company agrees to reimburse you, for the account of the several
Underwriters, for blue sky fees and related disbursements (including counsel
fees and disbursements and cost of printing memoranda for the Underwriters) paid
by or for the account of the Underwriters or their counsel in qualifying the
Stock under state securities or blue sky laws and in the review of the offering
by the NASD.

     (k) The Company hereby agrees that, without the prior written consent of
Hambrecht & Quist LLC on behalf of the Underwriters, the Company will not, for a
period of 180 days following the commencement of the public offering of the
Stock by the Underwriters, directly or indirectly, (i) sell, offer, contract to
sell, make any short sale, pledge, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer or dispose of any shares of Common Stock or any
securities convertible into or exchangeable or exercisable for or any rights to
purchase or acquire Common Stock or (ii) enter into any swap or other agreement
that transfers, in whole or in part, any of the economic consequences or
ownership of Common Stock, whether any such transaction described in clause (i)
or (ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise. The foregoing sentence shall not apply to (A)
the Stock to be sold to the Underwriters pursuant to this Agreement, (B) shares
of Common Stock issued by the Company upon the exercise of options granted under
the stock option plans of the Company (the "Option Plans") or upon the exercise
of warrants outstanding as of the date hereof, all as described in the
Preliminary Prospectus, and (C) options to purchase Common Stock granted under
the Option Plans.

     (l) If at any time during the 25-day period after the Registration
Statement becomes effective any rumor, publication or event relating to or
affecting the Company shall occur as a result of which in your opinion the
market price for the Stock has been or is likely to be materially affected
(regardless of whether such rumor, publication or event necessitates a
supplement to or amendment of the Prospectus), the Company will, after written
notice from you advising the Company to the effect set forth above, forthwith
prepare, consult with you concerning the substance of, and disseminate a press
release or other public statement, reasonably satisfactory to you, responding to
or commenting on such rumor, publication or event.

     (m) The Company is familiar with the Investment Company Act of 1940, as
amended, and has in the past conducted its affairs, and will in the future
conduct its affairs, in such a manner to ensure that the Company was not and
will not be an "investment company" or a company "controlled" by an "investment
company" within the meaning of the Investment Company Act of 1940, as amended,
and the rules and regulations thereunder.

     7.  INDEMNIFICATION AND CONTRIBUTION.

     (a) The Company agrees to indemnify and hold harmless each Underwriter and
each person (including each partner or officer thereof) who controls any
Underwriter within the meaning of Section 15 of the Securities Act from and
against any and all losses, claims, damages or liabilities, joint or several, to
which such indemnified parties or any of them may become subject under the
Securities Act, the Securities Exchange Act of 1934, as amended (herein called
the Exchange Act), or the common law or otherwise, and the Company agrees to
reimburse each such Underwriter and controlling person for any legal or other
expenses (including, except as otherwise hereinafter provided, reasonable fees
and disbursements of counsel) incurred by the respective indemnified parties in
connection with defending against any such losses, claims, damages or
liabilities or in connection with any investigation or inquiry of, or other
proceeding which may be brought against, the respective indemnified parties, in
each case arising out of or based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement
(including the Prospectus as part thereof and any Rule 462(b) registration
statement) or any post-effective amendment thereto (including any Rule 462(b)
registration statement), or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or (ii) any untrue statement or alleged untrue statement
of a material fact contained in any Preliminary Prospectus or the Prospectus (as
amended or as supplemented if the Company shall have filed with the Commission
any amendment thereof or supplement thereto) or the omission or alleged omission
to state therein a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; provided, however, that (1) the indemnity agreements of the Company
contained in this paragraph (a) shall not apply to any such losses, claims,
damages, liabilities or expenses if such statement or omission was made in
reliance upon and in conformity with information furnished as herein stated or
otherwise furnished in writing to the Company by or on behalf of any Underwriter
for use in any Preliminary Prospectus or the Registration Statement or the
Prospectus or any such amendment thereof or supplement thereto and (2) the
indemnity agreement contained in this paragraph (a) with respect to any
Preliminary Prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting any such losses, claims, damages, liabilities or
expenses purchased the Stock which is the subject thereof (or to the benefit of
any person controlling such Underwriter) if at or prior to the written
confirmation of the sale of such Stock a copy of the Prospectus (or the
Prospectus as amended or supplemented) was not sent or delivered to such person
and the untrue statement or omission of a material fact contained in such
Preliminary Prospectus was corrected in the Prospectus (or the Prospectus as
amended or supplemented) unless the failure is the result of noncompliance by
the Company with paragraph (c) of Section 6 hereof. The indemnity agreements of
the Company contained in this paragraph (a) and the representations and
warranties of the Company contained in Section 2 hereof shall remain operative
and in full force and effect regardless of any investigation made by or on
behalf of any indemnified party and shall survive the delivery of and payment
for the Stock.

     (b) Each Underwriter severally agrees to indemnify and hold harmless the
Company, each of its officers who signs the Registration Statement on his own
behalf or pursuant to a power of attorney, each of its directors, each other
Underwriter and each person (including each partner or officer thereof) who
controls the Company or any such other Underwriter within the meaning of Section
15 of the Securities Act, from and against any and all losses, claims,

                                       13

<PAGE>   14

damages or liabilities, joint or several, to which such indemnified parties or
any of them may become subject under the Securities Act, the Exchange Act, or
the common law or otherwise and to reimburse each of them for any legal or other
expenses (including, except as otherwise hereinafter provided, reasonable fees
and disbursements of counsel) incurred by the respective indemnified parties in
connection with defending against any such losses, claims, damages or
liabilities or in connection with any investigation or inquiry of, or other
proceeding which may be brought against, the respective indemnified parties, in
each case arising out of or based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement
(including the Prospectus as part thereof and any Rule 462(b) registration
statement) or any post-effective amendment thereto (including any Rule 462(b)
registration statement) or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading or (ii) any untrue statement or alleged untrue statement
of a material fact contained in the Prospectus (as amended or as supplemented if
the Company shall have filed with the Commission any amendment thereof or
supplement thereto) or the omission or alleged omission to state therein a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading, if such statement
or omission was made in reliance upon and in conformity with information
furnished as herein stated or otherwise furnished in writing to the Company by
or on behalf of such indemnifying Underwriter for use in the Registration
Statement or the Prospectus or any such amendment thereof or supplement thereto.
The indemnity agreement of each Underwriter contained in this paragraph (b)
shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any indemnified party and shall survive
the delivery of and payment for the Stock.

     (c) Each party indemnified under the provision of paragraphs (a) and (b) of
this Section 7 agrees that, upon the service of a summons or other initial legal
process upon it in any action or suit instituted against it or upon its receipt
of written notification of the commencement of any investigation or inquiry of,
or proceeding against, it in respect of which indemnity may be sought on account
of any indemnity agreement contained in such paragraphs, it will promptly give
written notice (herein called the Notice) of such service or notification to the
party or parties from whom indemnification may be sought hereunder. No
indemnification provided for in such paragraphs shall be available to any party
who shall fail so to give the Notice if the party to whom such Notice was not
given was unaware of the action, suit, investigation, inquiry or proceeding to
which the Notice would have related and was prejudiced by the failure to give
the Notice, but the omission so to notify such indemnifying party or parties of
any such service or notification shall not relieve such indemnifying party or
parties from any liability which it or they may have to the indemnified party
for contribution or otherwise than on account of such indemnity agreement. Any
indemnifying party shall be entitled at its own expense to participate in the
defense of any action, suit or proceeding against, or investigation or inquiry
of, an indemnified party. Any indemnifying party shall be entitled, if it so
elects within a reasonable time after receipt of the Notice by giving written
notice (herein called the Notice of Defense) to the indemnified party, to assume
(alone or in conjunction with any other indemnifying party or parties) the
entire defense of such action, suit, investigation, inquiry or proceeding, in
which event such defense shall be conducted, at the expense of the indemnifying
party or parties, by counsel chosen by such indemnifying party or parties and
reasonably satisfactory to the indemnified party or parties; PROVIDED, HOWEVER,
that (i) if the indemnified party or parties reasonably determine that there may
be a conflict between the positions of the indemnifying

                                       14

<PAGE>   15

party or parties and of the indemnified party or parties in conducting the
defense of such action, suit, investigation, inquiry or proceeding or that there
may be legal defenses available to such indemnified party or parties different
from or in addition to those available to the indemnifying party or parties,
then counsel for the indemnified party or parties shall be entitled to conduct
the defense to the extent reasonably determined by such counsel to be necessary
to protect the interests of the indemnified party or parties and (ii) in any
event, the indemnified party or parties shall be entitled to have counsel chosen
by such indemnified party or parties participate in, but not conduct, the
defense. If, within a reasonable time after receipt of the Notice, an
indemnifying party gives a Notice of Defense and the counsel chosen by the
indemnifying party or parties is reasonably satisfactory to the indemnified
party or parties, the indemnifying party or parties will not be liable under
paragraphs (a) through (c) of this Section 7 for any legal or other expenses
subsequently incurred by the indemnified party or parties in connection with the
defense of the action, suit, investigation, inquiry or proceeding, except that
(A) the indemnifying party or parties shall bear the legal and other expenses
incurred in connection with the conduct of the defense as referred to in clause
(i) of the proviso to the preceding sentence and (B) the indemnifying party or
parties shall bear such other expenses as it or they have authorized to be
incurred by the indemnified party or parties. If, within a reasonable time after
receipt of the Notice, no Notice of Defense has been given, the indemnifying
party or parties shall be responsible for any legal or other expenses incurred
by the indemnified party or parties in connection with the defense of the
action, suit, investigation, inquiry or proceeding.

     (d) If the indemnification provided for in this Section 7 is unavailable or
insufficient to hold harmless an indemnified party under paragraph (a) or (b) of
this Section 7, then each indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of the losses, claims, damages or liabilities
referred to in paragraph (a) or (b) of this Section 7 (i) in such proportion as
is appropriate to reflect the relative benefits received by each indemnifying
party from the offering of the Stock or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of each indemnifying party in connection with
the statements or omissions that resulted in such losses, claims, damages or
liabilities, or actions in respect thereof, as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Underwriters shall be deemed to be in the same respective proportions as the
total net proceeds from the offering of the Stock received by the Company and
the total underwriting discount received by the Underwriters, as set forth in
the table on the cover page of the Prospectus, bear to the aggregate public
offering price of the Stock. Relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by each indemnifying party and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission.

     The parties agree that it would not be just and equitable if contributions
pursuant to this paragraph (d) were to be determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method of allocation which does not take into account the equitable
considerations referred to in the first sentence of this paragraph (d). The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities, or actions in respect thereof, referred to in the first sentence
of this paragraph (d) shall be deemed to

                                       15

<PAGE>   16

include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigation, preparing to defend or defending against
any action or claim which is the subject of this paragraph (d). Notwithstanding
the provisions of this paragraph (d), no Underwriter shall be required to
contribute any amount in excess of the underwriting discount applicable to the
Stock purchased by such Underwriter. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this paragraph
(d) to contribute are several in proportion to their respective underwriting
obligations and not joint.

     Each party entitled to contribution agrees that upon the service of a
summons or other initial legal process upon it in any action instituted against
it in respect of which contribution may be sought, it will promptly give written
notice of such service to the party or parties from whom contribution may be
sought, but the omission so to notify such party or parties of any such service
shall not relieve the party from whom contribution may be sought from any
obligation it may have hereunder or otherwise (except as specifically provided
in paragraph (c) of this Section 7).

     (e) The Company will not, without the prior written consent of each
Underwriter, settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not such Underwriter or any
person who controls such Underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act is a party to such claim,
action, suit or proceeding) unless such settlement, compromise or consent
includes an unconditional release of such Underwriter and each such controlling
person from all liability arising out of such claim, action, suit or proceeding.

     8.  TERMINATION. This Agreement may be terminated by you at any time prior
to the Closing Date by giving written notice to the Company if after the date of
this Agreement trading in the Common Stock shall have been suspended, or if
there shall have occurred (i) the engagement in hostilities or an escalation of
major hostilities by the United States or the declaration of war or a national
emergency by the United States on or after the date hereof, (ii) any outbreak of
hostilities or other national or international calamity or crisis or change in
economic or political conditions if the effect of such outbreak, calamity,
crisis or change in economic or political conditions in the financial markets of
the United States would, in the Underwriters' reasonable judgment, make the
offering or delivery of the Stock impracticable, (iii) suspension of trading in
securities generally or a material adverse decline in value of securities
generally on the New York Stock Exchange, The Nasdaq National Market, or
limitations on prices (other than limitations on hours or numbers of days of
trading) for securities on either such exchange or system, (iv) the enactment,
publication, decree or other promulgation of any federal or state statute,
regulation, rule or order of, or commencement of any proceeding or investigation
by, any court, legislative body, agency or other governmental authority which in
the Underwriters' reasonable opinion materially and adversely affects or will
materially or adversely affect the business or operations of the Company, (v)
declaration of a banking moratorium by either federal or New York State
authorities or (vi) the taking of any action by any federal, state or local
government or agency in respect of its monetary or fiscal affairs which in the
Underwriters' reasonable opinion has a material adverse effect on the securities
markets in

                                       16

<PAGE>   17

the United States. If this Agreement shall be terminated pursuant to this
Section 8, there shall be no liability of the Company to the Underwriters and no
liability of the Underwriters to the Company; provided, however, that in the
event of any such termination the Company agrees to indemnify and hold harmless
the Underwriters from all costs or expenses incident to the performance of the
obligations of the Company under this Agreement, including all costs and
expenses referred to in paragraphs (i) and (j) of Section 6 hereof.

     9.  CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The obligations of the several
Underwriters to purchase and pay for the Stock shall be subject to the
performance by the Company of all its obligations to be performed hereunder at

purchased, as the case may be, and to the following further conditions:

     (a) The Registration Statement shall have become effective; and no stop
order suspending the effectiveness thereof shall have been issued and no
proceedings therefor shall be pending or threatened by the Commission.

     (b) The legality and sufficiency of the sale of the Stock hereunder and the

Closing Date by Testa, Hurwitz & Thibeault, LLP, counsel for the Underwriters.

     (c) You shall have received from Foley, Hoag & Eliot LLP, counsel for the
Company, an opinion, addressed to the Underwriters and dated the Closing Date,
covering the matters set forth in Annex A hereto, and if Option Stock is
purchased at any date after the Closing Date, additional opinion from such
counsel, addressed to the Underwriters and dated such later date, confirming
that the statements expressed as of the Closing Date in such opinion remain
valid as of such later date.

     (d) You shall be satisfied that (i) as of the Effective Date, the
statements made in the Registration Statement and the Prospectus were true and
correct and neither the Registration Statement nor the Prospectus omitted to
state any material fact required to be stated therein or necessary in order to
make the statements therein, respectively, not misleading, (ii) since the
Effective Date, no event has occurred which should have been set forth in a
supplement or amendment to the Prospectus which has not been set forth in such a
supplement or amendment, (iii) since the respective dates as of which
information is given in the Registration Statement and the Prospectus, there has
not been any material adverse change or any development which the Company has a
reasonable basis to believe may result in a prospective material adverse change
in the business, properties, financial condition or results of operations of the
Company, whether or not arising from transactions in the ordinary course of
business, other than as set forth in the Registration Statement and Prospectus,
and, since such dates, except in the ordinary course of business, the Company
has not entered into any material transaction not referred to in the
Registration Statement and the Prospectus, (iv) the Company does not have any
material contingent obligations which are not disclosed in the Registration
Statement and the Prospectus, (v) there is no action, suit, claim or proceeding

<PAGE>   18

government agency or body, or otherwise, that (a) reasonably would be expected
to have a material adverse effect, (b) reasonably would be expected to prevent
consummation of the transactions contemplated hereby or (c) is required to be
disclosed in the Registration Statement and not otherwise disclosed, (vi) there
are not any franchises, contracts, leases or other documents which are required
to be filed as exhibits to the Registration Statement which have not been filed
as required, (vii) the representations and warranties of the Company herein are
true and correct in all material respects as of the Closing Date or any later
date on which Option Stock is to be purchased, as the case may be, and (viii)
there has not been any material change in the market for securities in general
or in political, financial or economic conditions from those reasonably
foreseeable as to render it impracticable in your reasonable judgment to make a
public offering of the Stock, or a material adverse change in market levels for
securities in general (or those of companies in particular) or financial or
economic conditions which render it inadvisable to proceed.

     (e) You shall have received on the Closing Date and on any later date on
which Option Stock is purchased a certificate, dated the Closing Date or such
later date, as the case may be, and signed by the President and the Chief
Financial Officer of the Company, stating that the respective signers of said
certificate have carefully examined the Registration Statement in the form in
which it originally became effective and the Prospectus contained therein and
any supplements or amendments thereto, and that the statements included in
clauses (i) through (vii) of paragraph (d) of this Section 9 are true and
correct.

     (f) You shall have received from PricewaterhouseCoopers, LLP, a letter or
letters, addressed to the Underwriters and dated the Closing Date and any later

public accountants with respect to the Company within the meaning of the
Securities Act and the applicable published rules and regulations thereunder and
based upon the procedures described in their letter delivered to you
concurrently with the execution of this Agreement (herein called the Original
Letter), but carried out to a date not more than three business days prior to
the Closing Date or such later date on which Option Stock is purchased (i)
confirming, to the extent true, that the statements and conclusions set forth in
the Original Letter are accurate as of the Closing Date or such later date, as
the case may be, and (ii) setting forth any revisions and additions to the
statements and conclusions set forth in the Original Letter which are necessary
to reflect any changes in the facts described in the Original Letter since the
date of the Original Letter or to reflect the availability of more recent
financial statements, data or information. The letters shall not disclose any
change, or any development involving a prospective change, in or affecting the
business or properties of the Company which, in your sole judgment, makes it
impractical or inadvisable to proceed with the public offering of the Stock or
the purchase of the Option Stock as contemplated by the Prospectus.

     (g) You shall have been furnished evidence in usual written or telegraphic
form from the appropriate authorities of the several jurisdictions, or other
evidence satisfactory to you, of the qualification referred to in paragraph (f)
of Section 6 hereof.

     (h) Prior to the Closing Date, the Stock to be issued and sold by the
Company shall have been duly authorized for listing by the Nasdaq National

                                       18

<PAGE>   19

     (i) On or prior to the Closing Date, you shall have received from all
shareholders agreements, in form reasonably satisfactory to Hambrecht & Quist
LLC, stating that without the prior written consent of Hambrecht & Quist LLC on
behalf of the Underwriters, such person or entity will not, for a period of 180
days following the commencement of the public offering of the Stock by the
Underwriters, directly or indirectly, (i) sell, offer, contract to sell,
transfer the economic risk of ownership in, make any short sale, pledge or
otherwise transfer or dispose of any shares of Common Stock or any securities
convertible into or exchangeable or exercisable for or any other rights to
purchase or acquire Common Stock.

     All the agreements, opinions, certificates and letters mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if Testa, Hurwitz & Thibeault, LLP, counsel for the
Underwriters, shall be satisfied that they comply in form and scope.

     In case any of the conditions specified in this Section 9 shall not be
fulfilled, this Agreement may be terminated by you by giving notice to the
Company. Any such termination shall be without liability of the Company to the
Underwriters and without liability of the Underwriters to the Company; provided,
however, that (i) in the event of such termination, the Company agrees to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company under this Agreement,
including all costs and expenses referred to in paragraphs (i) and (j) of
Section 6 hereof, and (ii) if this Agreement is terminated by you because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein, to fulfill any of the conditions herein, or to comply with any
provision hereof other than by reason of a default by any of the Underwriters,
the Company will reimburse the Underwriters severally upon demand for all
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
that shall have been incurred by them in connection with the transactions
contemplated hereby.

     10.  CONDITIONS OF THE OBLIGATION OF THE COMPANY. The obligation of the
Company to deliver the Stock shall be subject to the conditions that (a) the
Registration Statement shall have become effective and (b) no stop order
suspending the effectiveness thereof shall be in effect and no proceedings
therefor shall be pending or threatened by the Commission.

     In case either of the conditions specified in this Section 10 shall not be
fulfilled, this Agreement may be terminated by the Company by giving notice to
you. Any such termination shall be without liability of the Company to the
Underwriters and without liability of the Underwriters to the Company; provided,
however, that in the event of any such termination the Company agrees to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company under this Agreement,
including all costs and expenses referred to in paragraphs (i) and (j) of
Section 6 hereof.

     11.  REIMBURSEMENT OF CERTAIN EXPENSES. In addition to its other
obligations under Section 7 of this Agreement, the Company hereby agrees to
reimburse on a quarterly basis the Underwriters for all reasonable legal and
other expenses incurred in connection with investigating or defending any claim,
action, investigation, inquiry or other proceeding arising out of or based upon
any statement or omission, or any alleged statement or omission, described

                                       19

<PAGE>   20

                                     ANNEX A

         MATTERS TO BE COVERED IN THE OPINION OF FOLEY, HOAG & ELIOT LLP
                             COUNSEL FOR THE COMPANY


     (i) The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the jurisdiction of its
incorporation, is duly qualified as a foreign corporation and in good standing
in each of the jurisdictions listed in Schedule __ hereto, and has full
corporate power and authority to own or lease its properties and conduct its

     (ii) the authorized capital stock of the Company consists of
shares of Preferred Stock, $.001 par value per share, of which there are no
outstanding shares, and        shares of Common Stock, $.001 par value per
share, of which there are outstanding        shares (including the
Underwritten Stock plus the number of shares of Option Stock issued on the date
hereof) and such additional number of shares, if any, as may have been issued
after        and prior to the Closing Date, pursuant to        ; proper
corporate proceedings have been taken validly to authorize such authorized
capital stock; all of the outstanding shares of such capital stock (including
the Underwritten Stock and the shares of Option Stock issued, if any) have been
duly and validly issued and are fully paid and nonassessable; any Option Stock
purchased after the Closing Date, when issued and delivered to and paid for by
the Underwriters as provided in the Underwriting Agreement, will have been duly
and validly issued and be fully paid and nonassessable; and no preemptive rights
of, or rights of refusal in favor of, shareholders exist with respect to the
Stock, or the issue and sale thereof, pursuant to the Certificate of
Incorporation or Bylaws of the Company and, to the knowledge of such counsel,
there are no contractual preemptive rights that have not been waived, rights of
first refusal or rights of co-sale which exist with respect to the issue and
sale of the Stock;

     (iii) the Registration Statement has become effective under the Securities
Act and, to the best of such counsel's knowledge, no stop order suspending the
effectiveness of the Registration Statement or suspending or preventing the use
of the Prospectus is in effect and no proceedings for that purpose have been
instituted or are pending or contemplated by the Commission;

     (iv) the Registration Statement, when filed and declared effective, and the
Prospectus, at the Closing Date (except as to the financial statements and
schedules and other financial data contained therein, as to which such counsel
need express no opinion) comply as to form in all material respects with the
requirements of the Securities Act and with the rules and regulations of the
Commission thereunder;

     (v) the information required to be set forth in the Registration Statement
in answer to Items 9, 10 (insofar as it relates to such counsel) and 11(c) of
Form S-1 is to the best of such counsel's knowledge accurately and adequately
set forth therein in all material respects or no response is required with
respect to such Items; the statements under the captions "Description of Capital
Stock" and "Shares Eligible for Future Sale"

                                       23

<PAGE>   24

in the Prospectus, insofar as such statements constitute matters of law or legal
conclusions, have been reviewed by such counsel and are accurate and complete
statements of the information called for with respect to such matters; and, to
the best of such counsel's knowledge, the description of the Company's stock
option plans and the options granted and which may be granted thereunder and the
options granted otherwise than under such plans set forth in the Prospectus
accurately and fairly presents the information required to be shown with respect
to said plans and options to the extent required by the Securities Act and the
rules and regulations of the Commission thereunder;

     (vi) to such counsel's knowledge, there are no agreements, franchises,
contracts, leases, documents or legal proceedings, pending or threatened, which
in the opinion of such counsel are of a character required to be described in
the Registration Statement or the Prospectus or to be filed as exhibits to the
Registration Statement, which are not described and filed as required;

     (vii) to the best of such counsel's knowledge, there is no action, suit or
proceeding, at law or in equity, pending against the Company before any court or
administrative agency, which, if determined adversely to the Company, would
materially adversely affect the business, operations, financial condition,
income or business prospects of the Company or prevent consummation of the
transactions contemplated by the Underwriting Agreement;

     (viii) the Underwriting Agreement has been duly authorized, executed and
delivered by the Company;

     (ix) the issue and sale by the Company of the shares of Stock sold by the
Company as contemplated by the Underwriting Agreement will not conflict with, or
result in a breach of, the Certificate of Incorporation or Bylaws of the Company
or any agreement or instrument known to such counsel to which the Company is a
party or any applicable law or regulation, or so far as is known to such
counsel, any order, writ, injunction or decree, of any jurisdiction, court or
governmental instrumentality;

     (x) [except as set forth in the Registration Statement and Prospectus,] no
holders of shares of Common Stock or other securities of the Company have
registration rights with respect to securities of the Company; and all holders
of securities of the Company having rights to the registration of shares of
Common Stock, or other securities, because of the filing of the Registration
Statement by the Company have waived such rights or such rights have expired by
reason of lapse of time following notification of the Company's intent to file
the Registration Statement;

     (xi) each consent, approval, authorization, order, designation, declaration
or filing by or with any United States Federal, State or foreign regulatory,
administrative or other governmental agency or body or court is required in
connection with the execution and delivery by the Company of the Underwriting
Agreement and the consummation of the transactions contemplated in the
Underwriting Agreement, except such as have been obtained under the Securities
Act, such additional steps as may be required by the NASD

                                       24

<PAGE>   25


and such as may be required under state securities or blue sky laws in
connection with the purchase and distribution of the Stock by the Underwriters;

     (xii) the Stock issued and sold by the Company will been duly authorized
for listing by the Nasdaq National Market upon official notice of issuance;

     (xiii) the Company is not, and upon consummation of the transactions
contemplated by the Underwriting Agreement and application of the net proceeds
from the sale of the Stock as set forth under the caption "Use of Proceeds" in
the Prospectus, will not be, an "investment company" within the meaning of the
Investment Company Act of 1940, as amended, and the rules and regulations
thereunder; and

     (xiv) assuming the Underwriters purchased such Stock in good faith and
without notice of any adverse claim within the meaning of Section 8-302 of the
Uniform Commercial Code as in effect in the Commonwealth of Massachusetts, when
certificates therefor have been delivered and paid for by the Underwriters as
provided in the Underwriting Agreement, the Underwriters will have acquired good
and valid title in such stock free of any such adverse claim.

     In addition to the matters set forth above, counsel rendering the foregoing
opinion shall also include a statement to the effect that nothing has come to
the attention of such counsel that leads them to believe that the Registration
Statement (except as to the financial statements, including the notes thereto,
and the other financial, accounting and statistical data contained therein at
the Effective Date (but after giving effect to changes incorporated pursuant to
Rule 430A under the Act) contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading, or that the Prospectus (except as to
the financial statements, including the notes thereto, and the other financial,
accounting and statistical data contained therein), as of its date or at the
Closing Date (or any later date on which Option Stock is purchased), contained
or contains any untrue statement of a material fact or omitted or omits to state
a material fact necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. With respect to
such statement, such counsel may state that their belief is based upon the
procedures set forth therein, but is without independent check or verification.

         2.2.1 License to Integrate MicroStrategy Product. MicroStrategy grants
         to Netgen a non-exclusive, non-transferable and royalty-free license to
         reproduce, create derivative works of and use copies of the

         Netgen Product to create the Integrated Product; (ii) develop Product
         Releases, Update Releases, and Version Releases of the Integrated
         Product; and (iii) maintain and support the Integrated Product and

         2.2.2 License to Copy and Distribute Documentation. MicroStrategy
         grants to Netgen a non-exclusive, non-transferable and royalty-free

         Integrated Product.

         2.2.3 License to Demonstrate. MicroStrategy grants to Netgen a

         but only as provided in


                                       3
<PAGE>   4
         Exhibit F. Netgen shall take all reasonable precautions against
         unauthorized disclosure or copying of the MicroStrategy Product while
         the Integrated Product is being demonstrated. Netgen shall take all
         reasonable steps to ensure that the MicroStrategy Product is
         inaccessible during inactive demonstration times, delete any
         demonstration copies of the MicroStrategy Product upon completion of
         any demonstration at a customer site and further exercise commercially
         reasonable efforts to ensure the security of the MicroStrategy Product.

         2.2.4 License to Grant Evaluation Licenses. MicroStrategy grants to
         Netgen a non-exclusive, non-transferable and royalty-free license to
         allow Evaluations of the MicroStrategy Product solely as part of the
         Integrated Product, but only pursuant to an end-user license agreement
         substantially equivalent in terms to the "net.Genesis Software License
         Agreement" attached hereto as Exhibit B. Netgen may copy the
         MicroStrategy Product for Evaluation, but only as provided in
         Exhibit F.

         2.2.5 License to Distribute as Part of Integrated Product.
         MicroStrategy grants to Netgen the nonexclusive, non-transferable
         worldwide right to reproduce, market, sublicense and distribute copies
         of the MicroStrategy Product on disk, CD-ROM, or via electronic
         download, solely as part of the Integrated Product. Except as otherwise
         set forth in Section 2.2.6, this is not a license to market, sublicense
         or distribute the MicroStrategy Products or user documentation
         separately nor permit the use of the MicroStrategy Products outside of
         the Integrated Application, and such action shall be a material breach
         of this Agreement.

         2.2.6 License to Distribute Existing MicroStrategy Product.
         MicroStrategy grants to Netgen the nonexclusive, non-transferable
         worldwide right to distribute copies of the MicroStrategy Product,
         unbundled, until release of the Integrated Product, but only pursuant
         to a written sublicense agreement that, in addition to including
         restrictions substantially similar to those contained in the
         "net.Genesis Software License Agreement" attached hereto as Exhibit B,
         explicitly states that the unbundled MicroStrategy Product may be used
         only with the Netgen Products (the "Combined Solution"). This right
         shall automatically expire by June 30, 2000. Netgen must replace the
         Combined Solution with the Integrated Product for all End Users who
         receive a license to the Combined Solution within six (6) months of the
         release of the Integrated Product. Except as otherwise set forth in
         Section 2.2.6, this is not a license to market, sublicense or
         distribute the MicroStrategy Products or user documentation separately
         nor permit the use of the MicroStrategy Products outside of the
         Integrated Application, and such action shall be a material breach of
         this Agreement.

         2.3 Terms of Distribution. Except as otherwise set forth in Section
         2.2.6, Netgen agrees that it will distribute the MicroStrategy Product
         as permitted in section 2.2 only pursuant to an end-user license
         agreement substantially equivalent in terms to the "net.Genesis End
         User License Agreement" attached hereto as Exhibit B.


                                       4
<PAGE>   5
This "net.Genesis End User License Agreement" shall at a minimum: (a) restrict
use of the MicroStrategy Products to use as part of the Integrated Solution; and
(b) restrict use of the MicroStrategy Product to use for analysis of the Web
traffic data combined with other enterprise data sources captured and correlated
by the Integrated Product.

2.4 License Restrictions. Netgen agrees that it shall not, and shall not permit
others to, decompile, disassemble, reverse engineer or otherwise decode or
derive source code of the MicroStrategy Product. In addition, Netgen shall not
rent the Integrated Products, provide third parties with access to the
Integrated Products through a service bureau or commercial time-sharing
arrangement or use the Integrated Products for outsourcing without the prior
written approval of MicroStrategy, which approval shall not be unreasonably
withheld.

2.5 Sublicensing Rights. The licenses granted in Section 2.2 may be sublicensed
to Resellers and OEMs who have executed written agreements with Netgen
containing terms at least as restrictive as those contained herein for the
purpose of facilitating distribution of the Integrated Product and/or creating
and distributing OEM Products. Netgen shall report to MicroStrategy on a monthly
basis the names of all Resellers and OEMs it has sublicensed hereunder.

3.       ROYALTIES, PAYMENT TERMS, AND RECORDS

3.1 Royalty Rate. Beginning on October 1, 1999, Netgen shall pay MicroStrategy
[*] Where Netgen sells more than [*] Named User Licenses for the Integrated
Product or the Combined Solution to a given End User, Netgen shall pay
MicroStrategy the fees set forth in Exhibit A for each Named User over [*].

3.2 Reports. Netgen shall prepare and maintain complete and accurate books and
records documenting the licensing of the Integrated Product or Combined Solution
and any compensation received therefrom. In addition, Netgen shall compile
quarterly financial results detailing total product revenue and total
maintenance revenue. Within forty-five (45) days of the close of each quarter,
Netgen shall report to MicroStrategy, in writing, the sale of Integrated
Products or Combined Solutions from the previous quarter including the name,
address and contact person for each customer, a copy of its quarterly financial
statement and the total royalty due MicroStrategy (the "Royalty Report").

3.3 Payments. All payments to MicroStrategy shall be denominated and made in
U.S. dollars, and are due within thirty (30) days of transmitting the Royalty
Report. Payments will be conducted via check drawn from a U.S. bank, or via
cable transfer of funds to a bank account to be specified by MicroStrategy.
Prices listed are exclusive of any shipping costs, import duties, transfer fees,
sales, use, value-added, privilege, excise or

                                       5

similar taxes or duties levied upon MicroStrategy, or any other charges or
assessments established by any government agency that are based upon licensing
of the MicroStrategy Product or Integrated Product pursuant to this Agreement,
all of which shall be paid by Netgen with the exception of taxes, duties or fees
based on MicroStrategy's net income.

3.4 Audit Rights. During the term of this Agreement and for a period of two (2)
years thereafter, MicroStrategy shall have the right, at its expense and upon
reasonable notice, to have examined by an independent, certified public
accountant subject to mutually acceptable nondisclosure agreement, Netgen's
books and records once each calendar year, in order to determine and verify
performance under this Agreement. Any discrepancy between royalties paid and
royalties actually due discovered pursuant to such examination shall be payable
within thirty (30) days of completion of the examination. In the event that an
audit discloses underpayment by Netgen of at least (5%) Netgen shall reimburse
MicroStrategy for the costs incurred in conducting the audit.

3.5 Renegotiation. Any time after the first year of this agreement, if more than
[*] is derived from products other than its Web analysis products, which shall
embed the MicroStrategy Products, then Netgen may request a re-negotiation of
the Royalties. Netgen may request such a re-negotiation by sending MicroStrategy
written notification that the threshold has been crossed and Netgen desires to
re-negotiate the royalties. Once Microstrategy receives the notice of
re-negotiation, the parties will meet and confer within ten (10) business days
to choose an independent auditor to determine the percentage of [*] that is not
attributable to Web analysis products and report back to both companies. The
percentage of revenue not attributable to Web analysis products that embed the
MicroStrategy Products shall then be carved out of the [*] definition for future
quarters. Any time after the renegotiated rates take effect, if less than [*] is
derived from products other than Web analysis products then MicroStrategy may
request a re-negotiation of the Royalties. MicroStrategy shall be required to
give Netgen notice of the re-negotiation. If MicroStrategy notifies Netgen of
the re-negotiation, then the definition of [*] shall be reset to the current
definition.

4.       MICROSTRATEGY DEVELOPMENT AND MARKETING ASSISTANCE TO NETGEN

4.1 Public Statements. The parties will agree in advance to the text of all
press releases and public disclosures associated with activities under this
Agreement, including without limitation any termination or expiration of this
Agreement. The parties will issue a joint release announcing the joint business
relationship.

the option to participate in each other's beta programs. MicroStrategy will
ensure that Netgen be a high-priority alpha and beta site for the MicroStrategy

high-priority developer level support and first mover advantage over all other
Web analysis companies.

4.3 Cooperative Marketing Plan. Netgen and MicroStrategy will exercise their
reasonable endeavors within sixty (60) days of the signing of this Agreement to
draw up a cooperative marketing plan.

4.4 Development Partner Designation. MicroStrategy will work with Netgen and use
commercially reasonable efforts to create a unique, distinct classification for
the partnership and MicroStrategy will not remove this designation during the
term of this Agreement without giving Netgen at least twelve (12) months prior
notice of the change in designation. This classification will enable Netgen to
develop and market a product or interface (to be defined) that will be uniquely
promoted by MicroStrategy to its customer base royalty-free. The purpose of this
is to "seed" the MicroStrategy market with an opportunity to collect Web data.

4.5 Co-Development Efforts. MicroStrategy agrees to co-locate a Netgen engineer
with the development team for the MicroStrategy Product, at mutually agreed upon
times, to use best efforts to incorporate Netgen's feature requirements
necessary to build the Integrated Product, and to otherwise provide the
development support more fully set forth in Exhibit C.

4.6 Right of First Refusal. MicroStrategy agrees to grant Netgen a right of
first refusal to license any new MicroStrategy Product on terms and conditions
substantially identical hereto. However, notwithstanding the foregoing,
MicroStrategy reserves the right to charge additional fees for certain products
if MicroStrategy determines, in its reasonable judgement, that the nature of the
product warrants such additional fees.

4.7 Non-Compete Notification. During the term of this Agreement, MicroStrategy
agrees that it will promote Netgen as a value-added partner. If MicroStrategy
enters the Web analysis business, either through acquisition or development of
an integrated Web analysis software product that combines collection and
analysis of Web site visitor behavior information and correlation of this
behavioral data with other business information on a stand-alone basis in direct
competition with Netgen, MicroStrategy shall give Netgen ninety (90) days prior
written notice before delivering such Web analysis software product to market.
If MicroStrategy provides such notice to Netgen, then Netgen may cancel this
Agreement within ninety (90) days of its receipt of such notice.

6.       TERM AND TERMINATION OF AGREEMENT

Agreement, the duties and rights of the parties shall be as follows:

         6.4.1 Netgen's rights granted under this Agreement will terminate and,
         except as provided herein, Netgen shall immediately cease reproduction,
         distribution and use of the MicroStrategy Product and Documentation, or
         any related technical or marketing material. Netgen shall immediately
         return to MicroStrategy all Master Disks, Documentation Media and other
         copies of the MicroStrategy Product and Documentation, as well as all
         MicroStrategy supplied copies of technical and marketing materials
         relating to the MicroStrategy Product or of the products of
         MicroStrategy. Netgen shall promptly return to MicroStrategy any
         Confidential Information belonging to MicroStrategy and MicroStrategy
         shall promptly return to Netgen any Confidential Information belonging
         to Netgen

         6.4.2 Within thirty (30) days of termination of this Agreement, a duly
         authorized officer of Netgen shall certify in writing that all of the
         items set forth in paragraph 6.4.1 above belonging to MicroStrategy
         have been returned to MicroStrategy and a duly authorized officer of
         MicroStrategy shall certify in writing that all of the items set forth

         Agreement. It is understood and agreed that the rights of termination
         and non-renewal set forth in this Agreement shall be absolute, that the
         parties have considered that expenses may be incurred in preparing for
         performance hereunder, and that financial loss or damage may result
         from such termination or non-renewal. It is the express intent of the
         parties that neither shall be liable to the other, for direct damages
         or incidental or consequential damages or of any kind otherwise, by
         reason of termination or non-renewal as herein provided.

         6.4.4 Notwithstanding the foregoing, upon termination, Netgen shall be
         entitled to retain thirty (30) copies of the MicroStrategy Product in
         order to support its existing customers. In the event that termination
         results from MicroStrategy's failure to maintain and upgrade the
         MicroStrategy Product as required by this Agreement, Netgen shall be
         entitled to use the source code of the MicroStrategy Product as
         provided in Section 12.

6.5 Survival. The provisions of Sections 2.4, 3.1 - 3.5, 6.4, 7, 8, 9, 10, 12
and 13 shall survive termination or expiration of this Agreement.

discretion, the correction of the MicroStrategy Product errors that cause breach
of the warranty, replacement of the MicroStrategy Product, or return of the fees
paid to MicroStrategy for the MicroStrategy Product upon Netgen's return of the

PARTY HERETO BE LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL OR
PUNITIVE DAMAGES, ARISING OUT OF THIS AGREEMENT. THE FOREGOING LIMITATION OF
LIABILITY SHALL APPLY REGARDLESS OF THE CAUSE OF ACTION UNDER WHICH SUCH DAMAGES
ARE SOUGHT, INCLUDING, WITHOUT LIMITATION, BREACH OF CONTRACT, NEGLIGENCE OR
OTHER TORT. THE FOREGOING LIMITATION DOES NOT APPLY TO DAMAGES ARISING FROM
PERSONAL INJURY CAUSED BY THE NEGLIGENCE OF EITHER PARTY. Except for amounts

(Indemnification Claims) or breaches of Section 10 (Confidentiality) in no event
shall either party's liability to the other party under this Agreement exceed
the amount of royalties paid by Netgen for the twelve (12) months preceding such
liability.

7.4 Year 2000 Warranty. MicroStrategy warrants to Netgen through June 30, 2000
that the unmodified MicroStrategy Products will not fail or produce incorrect
results when processing with four (4)-digit dates for the year 2000 or beyond;
provided, however, that MicroStrategy makes no warranty with respect to any such
failure or incorrect result that may arise due to: (i) the quality of the data
sought to be processed


                                       9
<PAGE>   10
with the Integrated Product; (ii) the effect of other software not licensed by
MicroStrategy to Netgen or developed by MicroStrategy for Netgen; or (iii) the
use of the software in an operating environment or on a platform not specified

For any breach of this warranty, Netgen's exclusive remedy and MicroStrategy's
entire liability shall be, at MicroStrategy's sole discretion, the correction of
the MicroStrategy Product errors that cause breach of the warranty, replacement
of the MicroStrategy Product, or return of the fees paid to MicroStrategy for
the MicroStrategy Product upon Netgen's return of the Product to MicroStrategy.

8.       INDEMNITY

8.1 Defense or Settlement of Claims. MicroStrategy agrees to defend, or at its
option to settle, any claim, suit or proceeding brought against Netgen based on
a third party claim that the MicroStrategy Product, as delivered to Netgen
pursuant to this Agreement, infringes upon any patent or upon any copyright or
violates the trade secret or other intellectual property rights of any third
party in the Territory (hereinafter "Infringement Claims"); provided
MicroStrategy is notified promptly in writing of an Infringement Claim and has
sole control over its defense or settlement, and Netgen provides reasonable
assistance in the defense of same.

8.2 Infringement Cures. Following notice of an Infringement Claim, or if

the request of Netgen or to meet any specifications provided by Netgen; (ii)
combination of a MicroStrategy Product with non-MicroStrategy programs, data,
hardware, or other materials, if such infringement claim would have been avoided
by the exclusive use of the unmodified MicroStrategy Product alone. For all
infringement claims to which this Subsection 8.3 is applicable, Netgen agrees to
indemnify and defend MicroStrategy, provided Netgen is notified promptly in
writing of an infringement claim and has sole control over its defense or
settlement, and MicroStrategy provides reasonable assistance in the defense of
same.

12.      ESCROW

12.1 Escrow Account. Within sixty (60) days of the Effective Date, MicroStrategy
agrees to deposit in an escrow account pursuant to an escrow agreement among
MicroStrategy and a third party escrow agent used by MicroStrategy (currently
Fort Knoxx) (the "Escrow Agent"), a copy of the source code of the MicroStrategy
Product (the "Escrow Material"). The escrow agreement shall contain, at a
minimum, the terms and conditions set forth in this Section 12. MicroStrategy
shall keep Escrow Material current and allow periodic audit by Escrow Agent of
compliance to this provision. Netgen shall bear all fees, expenses and other
costs to open and maintain such escrow account. If a Release Condition (as
defined in Section 12.2 below) occurs, and the Escrow Agent provides the Escrow
Material to Netgen in accordance with the escrow agreement, Netgen agrees to
hold all materials and information in the escrow account in strictest confidence
pursuant to the provisions contained in Section 10, and not to use them for any
purpose other than those purposes contemplated under Section 12.3 below.

12.2 Release. The Escrow Material shall remain under seal and unopened unless
and until a Release Condition occurs. Netgen shall notify MicroStrategy in
writing if it intends to seek release of the Escrow Material from the Escrow
Agent because (a) MicroStrategy has filed for bankruptcy under Chapter 7 or 11
of the Bankruptcy Act or a petition has been filed against MicroStrategy and
such petition has not been withdrawn or dismissed with prejudice within sixty
(60) days of such filing, (b) MicroStrategy ceases to do business in the
ordinary course for a period of at least sixty (60) days, or (c)


                                       13
<PAGE>   14
MicroStrategy materially breaches its support obligations under this Agreement,
and such breach remains uncured for a period of at least sixty (60) days after
MicroStrategy receives written notice of the breach from Netgen (the "Release
Conditions"). If MicroStrategy notifies Netgen in writing that it disputes
whether the Release Condition has occurred, officers of each of the parties
shall negotiate for a period of ten (10) business days to attempt to resolve the
dispute. At the end of such ten (10) business day period, if the parties have
not resolved the dispute, the matter shall be referred to arbitration in the
manner provided in Section 12.4 below.

12.3 License. Upon the release of the Escrow Material pursuant to section 12.2
above, Netgen shall have a non-exclusive, non-transferable license to use and
modify the Escrow Material as necessary to fully exercise the rights granted in
Section 2 hereof, including the right to use, modify and create derivative works
of the Escrow Material solely in order to maintain and support the Integrated
Product, and the right to modify and create derivative works of the Escrow
Material in order to create Product Releases, Version Releases and Update
Releases of the Integrated Product. Netgen shall not distribute, sell or
sublicense the Escrow Material. Subject to the licenses expressly granted in
this Agreement, MicroStrategy shall retain all right, title and interest in and
to the Escrow Material, including any modifications made thereto by Netgen. For
purposes of this section, Netgen may contract with and make the Escrow Material
available to a third party solely for the purpose of exercising its rights under
this section.

12.4 Arbitration. The parties agree that, if MicroStrategy reasonably disputes
the occurrence of the Release Condition as set forth above, it shall submit such
dispute for binding arbitration in accordance with the then-current commercial
arbitration rules of the American Arbitration Association ("Rules"). The
arbitration shall be conducted by one (1) arbitrator appointed in accordance
with the Rules. The sole question before the arbitrator shall be whether the
Release Condition existed at the time of Netgen's notice to MicroStrategy. If
the arbitrator finds that the Release Condition did exist at the time of
Netgen's notice to MicroStrategy, the Escrow Agent is hereby authorized to
release the Escrow Material to Netgen. The non-prevailing party in the
arbitration shall pay all fees and charges of the American Arbitration
Association; each party, however, shall be responsible for the payment of all
fees and expenses connected with the presentation of its respective case.

                            DRAFT - NOT FOR SIGNATURE
                     NET.GENESIS SOFTWARE LICENSE AGREEMENT

THIS IS A LEGAL AGREEMENT ("AGREEMENT") BETWEEN YOU AND NET.GENESIS CORPORATION
("NET.GENESIS").

1.       DEFINITIONS

A.       "Confidential Information" shall mean the Products, Product
         information, trade secrets and technical information disclosed in
         relation to this Agreement, the terms and pricing under this Agreement
         and all information clearly identified as confidential.

B.       "Product" shall mean a computer software program belonging to
         net.Genesis's net.Analysis(TM) software family that is identified on
         your invoice, for which you are granted a license pursuant to this
         Agreement ("Software"); the user guides and manuals associated with the
         Software ("Documentation"); and any and all Updates to, or patches and
         fixes for, the Software and Documentation. The term "Product" shall not
         include any code that has been modified or developed by you.

C.       "Technical Support Services" shall mean the maintenance and support
         provided by net.Genesis in accordance with net.Genesis's then-current
         technical support policies and procedures for the applicable
         Product(s).

D.       "Update" shall mean any subsequent release of Software and/or
         Documentation that is made generally available to licensees subscribing
         to Technical Support Services at no additional charge other than media
         and handling charges. Updates shall not include any release, option or
         future product that net.Genesis licenses separately.

E.       "Territory" shall mean all countries of the world, subject however to
         all applicable U.S. export restrictions.

2.       LICENSE

A.       net.Genesis grants to you a non-exclusive and non-transferable license
         to use the Software in object code form only for your own internal data
         processing and analysis operations, and to use the Documentation in
         support of such use of the Software in the Territory, subject to the
         terms and conditions of this Agreement. Your use of the Software is
         limited to the number of single or multiple CPU systems ("Managed
         Server Boxes") and number of users that are specified on your invoice.
         In addition to the Software specified on your invoice, and at no
         additional cost, net.Genesis grants to you a runtime license to use the
         net.Analysis Software Development Kit ("net.Analysis SDK") solely for
         the purpose of using the Product(s) or installing and using bug fixes
         and product enhancements from net.Genesis or its certified partners.

B.       net.Genesis grants to you a non-exclusive, non-transferable license to
         make object code copies of the Software for archival, disaster recovery
         and routine backup as is reasonably necessary. You may make a
         reasonable number of copies of the Documentation, or parts thereof, for
         internal use at your place of business. All titles, trademarks,
         copyright and restricted rights notices shall be reproduced in all
         Product copies. All copies of the Products are subject to the terms of
         this Agreement.

C.       net.Genesis shall retain all title, copyright and other proprietary
         rights in the Software and Documentation. You shall not acquire any
         rights, express or implied, in the Products, other than those specified
         in this Agreement.

3.       AUDIT

         net.Genesis shall have the right, at its expense, to conduct an audit
         to verify that you are using the Products to process and analyze data
         generated by the number of servers specified on your invoice, and that
         the Products are being used by the number of users specified on your
         invoice. Any such audit shall be conducted during regular business
         hours and shall not unreasonably interfere with your business
         activities. If an audit reveals that you have distributed or allowed
         use of the Products in excess


                                       18
<PAGE>   19
         of the use permitted by this Agreement, you shall pay net.Genesis for
         such unauthorized use based on the net.Genesis price list in effect at
         the time the audit is completed. If the underpaid fees exceed five
         percent (5%) of the license fees paid, then you shall pay net.Genesis's
         reasonable costs of conducting the audit. net.Genesis shall conduct
         audits not more than once per year; provided however that if the
         underpaid fees exceed five percent (5%) of the license fees paid then
         net.Genesis shall be entitled to conduct a second audit within the same
         year.

4.       UNAUTHORIZED USE

         You may not: (i) market, license, distribute, transfer, sublicense or
         otherwise commercially exploit the Software or Documentation; (ii)
         permit the use of the Software or Documentation by others or otherwise
         operate the Software for third parties (e.g., as a service bureau or
         data processing service); (iii) modify the Software or translate or
         port the Software or Documentation into any other computer or human
         language without the prior written consent of net.Genesis; (iv)
         disassemble, reverse engineer or decompile the Software or cause or
         permit reverse engineering, disassembly or decompilation of the
         Software, except to the extent that applicable law expressly allows
         such actions; (v) publish or provide the results of any benchmark or
         comparison tests run on the Software to any third party, without the
         prior written consent of net.Genesis; or (vi) sell, lend, rent, give,
         assign or otherwise transfer or dispose of the Software or the
         Documentation.

5.       LIMITED WARRANTIES AND DISCLAIMERS

A.       Software Warranty. net.Genesis warrants, for a period of ninety (90)
         days from the date the Software is delivered or, if the Software is
         installed by net.Genesis, from the date the Software is installed (the
         "Warranty Period") that the Software, if operated as directed, will
         substantially achieve the functionality described in the Documentation.
         net.Genesis also warrants that the unmodified Software will not produce
         errors processing date data in connection with the year change from
         December 31, 1999 to January 1, 2000 when used in accordance with the
         instructions, recommendations, and exceptions set forth in the
         Documentation, provided all other products (e.g., other software,
         firmware, and hardware) used with the Software properly exchange date
         data with the Software. Notwithstanding the foregoing, net.Genesis
         makes no warranty with respect to failures that are caused directly by
         the underlying hardware and operating system software on which the
         Software is used if such underlying hardware and operating system has
         not been approved by net.Genesis for use with the Software.

B.       Media Warranty. net.Genesis warrants that the media containing the
         Software, if provided by net.Genesis, is free from defects in material
         and workmanship under normal use for thirty (30) days from the date of
         your invoice.

C.       Conditions to Limited Warranties. The limited warranties in this
         Section 5 are conditioned upon your use of the Software in accordance
         with the instructions provided in the Documentation. The limited
         warranties set forth in this Section 5 shall not apply to the extent
         that an error occurs because of and would not have occurred but for:
         (i) modifications made to the Software by a party other than
         net.Genesis; (ii) your failure to implement enhancements provided to
         you by net.Genesis; or (iii) your use of the Software in connection
         with any computer equipment or devices not meeting the minimum
         requirements set forth in the Documentation.

D.       Disclaimers. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW,
         NET.GENESIS AND ITS SUPPLIERS DISCLAIM ALL OTHER WARRANTIES, EXPRESS OR
         IMPLIED, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY
         OR FITNESS FOR A PARTICULAR PURPOSE WITH REGARD TO THE SOFTWARE AND
         DOCUMENTATION.

         net.Genesis does not warrant that the Software will meet your
         requirements or operate with all equipment and software configurations.
         Furthermore, you acknowledge that due to the complex nature of computer
         software, however, it is impossible to ensure that the Software is
         completely error free, will operate without interruption or that all
         Software errors will be corrected. To the extent you obtain any
         pre-production releases of the Software, such Software is distributed
         "as is" with no warranty of any kind.

E.       Exclusive Remedies. For breach of any of the warranties contained in
         this Section 5, your exclusive remedy, and net.Genesis's entire
         liability, shall be: (i) to replace defective media returned within
         thirty (30) days of the date of your invoice; or (ii) at net.Genesis's
         sole discretion, to correct Software errors that cause breach of the
         warranty, to replace the Software, or to advise you how to achieve
         substantially the same functionality described in the Documentation.

6.       LIMITATION OF LIABILITY

         TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL
         NET.GENESIS OR ITS SUPPLIERS BE LIABLE FOR INDIRECT, INCIDENTAL,
         SPECIAL, OR CONSEQUENTIAL DAMAGES (INCLUDING, WITHOUT LIMITATION,
         DAMAGES FOR LOSS OF BUSINESS PROFITS, BUSINESS INTERRUPTION, LOSS OF
         BUSINESS INFORMATION, OR ANY OTHER PECUNIARY LOSS) ARISING OUT OF THE
         USE OR INABILITY TO USE THIS SOFTWARE, EVEN IF NET.GENESIS HAS BEEN
         ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. NET.GENESIS'S LIABILITY FOR
         DAMAGES HEREUNDER SHALL IN NO EVENT EXCEED THE AMOUNT OF LICENSE FEES
         PAID BY YOU UNDER THIS AGREEMENT.

7.       INTELLECTUAL PROPERTY RIGHTS AND CONFIDENTIALITY

A.       You acknowledge that the Software, including methods, processes or
         techniques utilized therein, are proprietary to and valuable trade
         secrets of net.Genesis and are protected by United States copyright law
         and international treaties. You shall take no actions that impair or
         infringe net.Genesis's intellectual property rights. You agree not to
         use, copy, modify, transfer, download, merge, make any translation or
         derivative work or otherwise deal with the Software except as expressly
         provided in this Agreement. In no event shall you cause or permit the
         disassembly, reverse compilation or other decoding of any Software. You
         agree not to remove or destroy any copyright notices, other proprietary
         markings or confidentiality legends placed upon or contained within the
         Software.

B.       During the term of this Agreement, each party may have access to the
         other party's Confidential Information. "Confidential Information"
         includes, without limitation, information pertaining to the parties'
         respective businesses and includes, without limitation, methods, plans,
         customers and/or projects and financial information. A party's
         Confidential Information shall not include information that: (i) is or
         becomes a part of the public domain through no act or omission of the
         other party; (ii) was in the other party's lawful possession prior to
         the disclosure and had not been obtained by the other party either
         directly or indirectly from the disclosing party; (iii) is lawfully
         disclosed to the other party by a third party without restriction on
         disclosure; or (iv) is independently developed by the other party.

C.       The parties agree to hold each other's Confidential Information in
         confidence during the term of this Agreement and for a period of two
         (2) years after termination of this Agreement. The parties agree that,
         unless required by law, they shall not make each other's Confidential
         Information available in any form to any third party or to use each
         other's Confidential Information for any purpose other than the
         implementation of this Agreement. Each party agrees to take all
         reasonable steps to ensure that Confidential Information is not
         disclosed or distributed by its employees or agents in violation of the
         terms of this Agreement. Furthermore, you agree not to use any
         Confidential Information of net.Genesis to create any computer software
         program or user documentation that is substantially similar to any
         net.Genesis product.


8.       TECHNICAL SUPPORT SERVICES

         net.Genesis provides Technical Support Services (including product
         maintenance and upgrades) only through separate Support Agreements.
         Please contact net.Genesis if you want to obtain support through the
         execution of such agreement.

9.       TERM AND TERMINATION

A.       Term. This Agreement shall remain in effect until terminated in
         accordance with this Section 9. If not terminated as provided herein,
         the license granted under this Agreement shall remain in effect
         perpetually.

B.       Termination by net.Genesis. net.Genesis may terminate this Agreement or
         any license upon written notice if you have materially breached the
         terms and conditions of this Agreement and fail to correct the breach
         within thirty (30) days following written notice informing you of the
         breach.

C.       Termination by You. You may terminate any license or this Agreement at
         any time; termination shall not, however, relieve you of the
         obligations specified in Sections 9.D and 9.E below.



                                       20
<PAGE>   21
D.       Effect of Termination. Termination of this Agreement or any license
         shall not prevent either party from pursuing other remedies available
         to it, including injunctive relief, nor shall such termination relieve
         your obligation to pay all fees that have accrued or are otherwise owed
         by you under this Agreement.

E.       Handling of Products upon Termination. If the license granted under
         this Agreement expires or otherwise terminates, you shall: (a) cease
         using the applicable Products, and (b) certify to net.Genesis within
         thirty (30) days after expiration or termination that you have
         destroyed or have returned to net.Genesis the Products and all copies
         thereof and any Confidential Information in your possession or control;
         provided, however, that in the event that only certain licenses granted
         under this Agreement expire or are terminated, you may retain any
         Confidential Information that relates to the licenses you continues to
         hold. This requirement applies to copies in all forms, partial and
         complete, in all types of media and computer memory, and whether or not
         modified or merged into other materials.

10.      INVOICING AND PAYMENT

         All fees shall be calculated based upon net.Genesis's prices in effect
         at the time of any quote or order, as applicable. All fees shall be
         payable thirty (30) days from the date of invoice, and shall be deemed
         overdue if they remain unpaid thereafter. Any amounts payable by you
         hereunder which remain unpaid after the due date shall be subject to a
         late charge equal to one and one-half percent (1.5%) per month or the
         highest rate allowable by law, whichever is lower, from the due date
         until such amount is paid. You agree to pay applicable shipping and
         handling charges. If your procedures require you to issue a purchase
         order, all purchase orders or ordering documents shall be governed by
         the terms of this Agreement. In no event shall the terms of any
         purchase order you issue to net.Genesis be given any force or effect.

11.      GENERAL

A.       Governing Law. This Agreement is governed by the laws of the
         Commonwealth of Massachusetts, excluding the application of its
         conflict of laws provisions. The federal and state courts of

C.       Waiver. To be enforceable, any waiver of this Agreement or any
         provision thereof must be in writing and signed by the waiving party.
         Should either party waive or excuse a breach by the other party, such
         waiver shall not constitute a consent to, waiver of, or excuse of any
         different or subsequent breach, whether or not of the same kind as the
         original breach.

D.       Severability. If for any reason a court if competent jurisdiction finds
         any provision or portion of this Agreement to be unenforceable, that
         provision will be enforced to the maximum extent permissible so as to
         effect the intent of the parties, and the remainder of this Agreement
         will continue in full force and effect.

E.       Export Restrictions. The Software may be subject to the export controls
         of the United States Departments of State and Commerce and you agree to
         comply fully with all applicable U.S. regulations governing the export,
         destination, ultimate end user and other restrictions relating to the
         Software.

F.       U.S. Government Restricted Rights. Software acquired with United States
         Federal Government funds or intended for use within or for any United
         States federal agency are provided with "LIMITED RIGHTS" and

H.       Force Majeure. Neither party will be responsible for failure of
         performance, other than for an obligation to pay money, due to causes
         beyond its control, including, without limitation, acts of God or
         nature; labor disputes; sovereign acts of any federal, state or foreign
         governments; or shortage of materials.

         2.04 Representations by the Purchasers. All representations and
warranties of the Purchasers in this Section 2.04 are made severally and not
jointly as follows:

                  (a) Each Purchaser represents that it is acquiring the
         Purchased Shares and any Conversion Shares for its own account and for
         the purpose of investment and not with a view to distribution or resale
         thereof; subject, nevertheless, to the condition that the disposition
         of the property of each Purchaser shall at all times be within its
         control, subject to applicable law and contractual restrictions. Each
         Purchaser which is not an individual further represents and warrants
         that it was not organized for the specific purpose of acquiring the
         Purchased Shares. Each Purchaser further represents and warrants that
         such Purchaser is (or, in the case of a partnership, it and all of its
         partners are) an "accredited investor" for purposes of the Securities
         Act (unless otherwise indicated on Exhibit 2.01A hereto) and Regulation
         D thereunder and warrants that it has knowledge and experience in
         financial and business matters such that it is capable of evaluating
         the merits and risks of the investment to be made hereunder, and that
         such Purchaser is financially able to undertake the risks involved in
         such an investment. Each Purchaser further acknowledges that it has had
         a full opportunity to request from the Company and to review and has
         received all information which it deems relevant in making an informed
         and knowledgeable decision to purchase the Purchased Shares being
         purchased by it hereunder. Each Purchaser understands and agrees that
         (i) the Purchased Shares and the Conversion Shares have not been
         registered under the Securities Act by reason of their issuance in a
         transaction exempt from the registration requirements of the Securities
         Act pursuant to Section 4(2) or Regulation D promulgated thereunder,
         (ii) the Purchased Shares and the Conversion Shares must be held
         indefinitely unless a registration statement covering such shares is
         effective under the Securities Act or unless an exception from
         registration under such Act is available, (iii) the Purchased Shares
         and the Conversion Shares will bear a legend to that effect and (iv)
         the Company will make a notation on its transfer books to such effect.
         Each Purchaser not an Accredited Investor makes the representations in
         this Section 2.04 except as to his status as an Accredited Investor.

                  (b) The principal office or residence of each Purchaser, and
         the place at which the decision to participate in this Agreement and
         the transactions contemplated hereby was made is located at the address
         appearing below such Purchaser's name on Exhibit 2.01A hereto. Each
         Purchaser which is not an individual and whose address appearing below
         such Purchaser's name on Exhibit 2.01A is located in Massachusetts
         further represents that it is an "institutional buyer" as that term is
         used in Section 402 (b) (8) of the Massachusetts Uniform Securities
         Act.

                  (c) Each Purchaser represents and warrants that this Agreement
         and all transactions contemplated hereunder have been duly authorized
         by all necessary action on its part and that this Agreement has been
         duly executed and delivered by it or on its behalf and is a valid and
         binding agreement enforceable against it in accordance with its terms.

<PAGE>   6
                  (d) Each Purchaser represents that no person, firm or
         corporation has or will have, as a result of any act or omission by
         such Purchaser, any right, interest or valid claim against the Company
         for any commission, fee or other compensation as a finder or broker, or
         in any similar capacity, in connection with the transactions
         contemplated by this Agreement.

valid, binding and enforceable against the Company in accordance with their
terms. Sufficient shares of authorized but unissued Common Stock of the Company
have been reserved by appropriate corporate action in connection with the
prospective conversion of the Purchased Shares. The issuance of the Purchased
Shares, and the issuance of the Conversion Shares upon the conversion of the
Purchased Shares, are not subject to preemptive or other preferential rights, or

sale, execution or delivery by the Company, or for the performance by it of its
obligations under, this Agreement, the agreements referred to in Article III
hereof or the Purchased Shares shall have been made prior to, and shall be

investigation pending or, to the knowledge of the Company, threatened against
the Company affecting any of its properties or assets, or, to the knowledge of
the Company, after due inquiry, against any officer, Key Employee or principal
stockholder of the Company that might result, either in any case or in the
aggregate, in any material adverse change in the business, operations, affairs
or condition of the Company, or any of its properties or assets, or pending or,
to the knowledge of the Company, threatened against the Company that might call
into question the validity of this Agreement, the issuance of the Purchased
Shares, or any action taken or to be taken pursuant hereto or thereto. Neither
the Company nor, to the knowledge of the Company, after due inquiry, any
officer, Key Employee or principal stockholder of the Company or its
Subsidiaries, is in default with respect to any order, writ, injunction, decree,
ruling or decision of any court, commission, board or other government agency
that might result, either in any case or in the aggregate, in any material
adverse change in the business, operations, affairs or condition of the Company
or any of its properties or assets. The foregoing sentences include, without
limiting their generality, actions pending or threatened (or any basis therefor
known to the Company) involving the prior employment of employees of the Company
and the use in any of the Company's business of any information or techniques
allegedly proprietary to any of their former employers.

         4.05 Certain Agreements of Officers and Employees.

                  (a) To the best of the Company's knowledge and belief, after
         due inquiry, no employee of the Company is in violation of any material
         term of any employment contract, patent disclosure agreement,
         non-competition agreement, or any other contract or agreement or any
         restrictive covenant relating to the right of any such officer or
         employee to be employed by the Company because of the nature of the
         business conducted by the Company or relating to the use of trade
         secrets or proprietary information of others, and to the best of the
         Company's knowledge and belief, the continued employment of the
         Company's officers and employees do not subject the Company or the
         Purchasers to any liability arising from such agreements.

                  (b) To the Company's knowledge, no officers of the Company,
         nor any Key Employees of the Company whose termination, either

         with the Company.

                  (c) The Company is not a party to any collective bargaining
         agreement and, to the best of its knowledge, after due inquiry, there

documents, as amended, and by-laws, as amended, and in all material respects
with the terms and provisions of each material mortgage, indenture, lease,
agreement and other instrument relating to obligations of the Company, and, to
the best of the Company's knowledge, of all material judgments, decrees,
governmental orders, statutes, rules or regulations by which it is bound or to
which its properties or assets are subject. Neither the execution and delivery
of this Agreement or the Purchased Shares, nor the consummation of any
transaction contemplated hereby or thereby, has constituted or resulted in or
will constitute or result in a default or violation of any material term or
provision in any of the foregoing documents or instruments.

         4.07 Federal Reserve Regulations. The Company is not engaged in the
business of extending credit for the purpose of purchasing or carrying margin
securities (within the meaning of Regulation G of the Board of Governors of the
Federal Reserve System), and no part of the proceeds of the Purchased Shares
will be used to purchase or carry any margin security or to extend credit to
others for the purpose of purchasing or carrying any margin security or in any
other manner which would involve a violation of any of the regulations of the
Board of Governors of the Federal Reserve System.

         4.08 Title to Assets. The company has good and marketable title in fee
to such of its fixed assets as are real property, and good title to all of its
other assets now carried on its books, including those reflected in the most
recent balance sheet of the Company described below in Section 4.10, or acquired
since the date of such balance sheet (except personal property disposed of since
said date in the ordinary course of business) free of any mortgages, pledges,
charges, liens, security interests or other encumbrances, except those indicated
in Exhibit 4.08 hereto and except for liens for current taxes not yet due and
payable and minor imperfections of title, if any, not material in nature or
amount and not materially detracting from the value or impairing the use of the
property subject thereto or impairing the operations of the Company. The Company
enjoys peaceful and undisturbed possession under all leases under which it is
operating and is in compliance in all material respects with all such leases,
and all said leases are valid and subsisting and in full force and effect.

         4.09 Patents and Intellectual Property Rights. The Company owns or has
a valid right, or will be able to obtain at reasonable cost standard in the
industry the right, to use the patents, patent rights, licenses, trade secrets,
trademarks, trademark rights, trade names or trade name rights or franchises,
copyrights, inventions, and


                                      -9-
<PAGE>   10
intellectual property rights material to the conduct of its businesses as now
operated (the "Company's Intellectual Property"); and no claim is pending to the
effect that the operations of the Company, and to the Company's knowledge, the
operations of the Company will not, conflict with valid patents, patent rights,
licenses, trade secrets, trademarks, trademark rights, trade names or trade name
rights or franchises, copyrights, inventions, and intellectual property rights
of others. Except as set forth in Exhibit 4.09 hereto, and except for the
payment of the customary fees for the right to use commercially available
software, the Company has no obligation to compensate any Person for the use of
any of the Company's Intellectual Property and has granted to no Person any
license or other rights to use in any manner any of the Company's Intellectual
Property, whether requiring the payment of royalties or not.

provisions of the Securities Act.

         4.20 No Brokers or Finders. No Person has or will have, as a result of
the transactions contemplated by this Agreement, any right, interest or valid

offer and sale of all shares of capital stock or other securities of the Company
issued before the Closing complied with or were exempt from registration or
qualification under all federal and state securities laws. No securities of the
Company have been issued prior hereto at a price which would result in an
increase in the number of shares of Common Stock issuable upon conversion of any
outstanding shares of any series or subseries of Series A Preferred Stock or
Series B Preferred Stock pursuant to the provisions of Article Fourth, A, 5(e)
or (f) of the Charter.

         2.04 Representations by the Purchasers. All representations and
warranties of the Purchasers in this Section 2.04 are made severally and not
jointly as follows:

                  (a) Each Purchaser represents that it is acquiring the
         Purchased Shares and any Conversion Shares for its own account and for
         the purpose of investment and not with a view to distribution or resale
         thereof; subject, nevertheless, to the condition that the disposition
         of the property of each Purchaser shall at all times be within its
         control, subject to applicable law and contractual restrictions. Each
         Purchaser which is not an individual further represents and warrants
         that it was not organized for the specific purpose of acquiring the
         Purchased Shares. Each Purchaser further represents and warrants that
         such Purchaser is (or, in the case of a partnership, it and all of its
         partners are) an "accredited investor" for purposes of the Securities
         Act (unless otherwise indicated on Exhibit 2.01A hereto) and Regulation
         D thereunder and warrants that it has knowledge and experience in
         financial and business matters such that it is capable of evaluating
         the merits and risks of the investment to be made hereunder, and that
         such Purchaser is financially able to undertake the risks involved in
         such an investment. Each Purchaser further acknowledges that it has had
         a full opportunity to request from the Company and to review and has
         received all information which it deems relevant in making an informed
         and knowledgeable decision to purchase the Purchased Shares being
         purchased by it hereunder. Each Purchaser understands and agrees that
         (i) the Purchased Shares and the Conversion Shares have not been
         registered under the Securities Act by reason of their issuance in a
         transaction exempt from the registration requirements of the Securities
         Act pursuant to Section 4(2) or Regulation D promulgated thereunder,
         (ii) the Purchased Shares and the Conversion Shares must be held
         indefinitely unless a registration statement covering such shares is
         effective under the Securities Act or unless an exception from
         registration under such Act is available, (iii) the Purchased Shares
         and the Conversion Shares will bear a legend to that effect and (iv)
         the Company will make a notation on its transfer books to such effect.
         Each Purchaser not an Accredited Investor makes the representations in
         this Section 2.04 except as to his status as an Accredited Investor.

                  (b) The principal office or residence of each Purchaser, and
         the place at which the decision to participate in this Agreement and
         the transactions contemplated hereby was made is located at the address
         appearing below such Purchaser's name on Exhibit 2.01A hereto. Each
         Purchaser which is not an individual and whose address appearing below
         such Purchaser's name on Exhibit 2.01A is located in Massachusetts
         further represents that it is an "institutional buyer" as that term is
         used in Section 402 (b) (8) of the Massachusetts Uniform Securities
         Act.

                  (c) Each Purchaser represents and warrants that this Agreement
         and all transactions contemplated hereunder have been duly authorized
         by all necessary action on its part and that this Agreement has been
         duly executed and delivered by it or on its behalf and is a valid and
         binding agreement enforceable against it in accordance with its terms.

                  (d) Each Purchaser represents that no person, firm or
         corporation has or will have, as a result of any act or omission by
         such Purchaser, any right, interest or valid claim against the Company
         for any commission, fee or other compensation as a finder or broker, or
         in any similar capacity, in connection with the transactions
         contemplated by this Agreement.

organized and validly existing corporation in good standing under the laws of
the jurisdiction in which it is organized and has all requisite corporate power
and authority for the ownership and operation of its properties and for the
carrying on of its business as now conducted. The Company is duly licensed or
qualified and in good standing as a foreign corporation authorized to do
business in The Commonwealth of Massachusetts and in each other jurisdiction in

                                      -7-
<PAGE>   8
         4.02 Corporate Action. The Company has all necessary corporate power
and has taken all corporate action required for the due authorization, execution
and delivery of this Agreement and any other agreements and instruments executed
in connection herewith and for the due authorization, issuance and delivery of
the Purchased Shares, and this Agreement and any such other agreements are
valid, binding and enforceable against the Company in accordance with their
terms. Sufficient shares of authorized but unissued Common Stock of the Company
have been reserved by appropriate corporate action in connection with the
prospective conversion of the Purchased Shares. The issuance of the Purchased
Shares, and the issuance of the Conversion Shares upon the conversion of the
Purchased Shares, are not subject to preemptive or other preferential rights, or
similar statutory or contractual rights, either arising pursuant to any
agreement or instrument to which the Company is a party or which are otherwise
binding upon the Company.

         4.03 Governmental Approvals. All authorizations, consents, approvals,
licenses, exemptions from or filings, or registrations with any court or
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, necessary for, or in connection with, the offer, issuance,
sale, execution or delivery by the Company, or for the performance by it of its
obligations under, this Agreement, the agreements referred to in Article III
hereof or the Purchased Shares shall have been made prior to, and shall be
effective as of, the Initial Closing (except for any post-sale filings that may
be required under federal or state securities laws, which will be filed by the
Company in a timely manner).

         4.04 Litigation. There is no litigation or governmental proceeding or
investigation pending or, to the knowledge of the Company, threatened against
the Company affecting any of its properties or assets, or, to the knowledge of
the Company, after due inquiry, against any officer, Key Employee or principal
stockholder of the Company that might result, either in any case or in the
aggregate, in any material adverse change in the business, operations, affairs
or condition of the Company, or any of its properties or assets, or pending or,
to the knowledge of the Company, threatened against the Company that might call
into question the validity of this Agreement, the issuance of the Purchased
Shares, or any action taken or to be taken pursuant hereto or thereto. Neither
the Company nor, to the knowledge of the Company, after due inquiry, any
officer, Key Employee or principal stockholder of the Company or its
Subsidiaries, is in default with respect to any order, writ, injunction, decree,
ruling or decision of any court, commission, board or other government agency
that might result, either in any case or in the aggregate, in any material
adverse change in the business, operations, affairs or condition of the Company
or any of its properties or assets. The foregoing sentences include, without
limiting their generality, actions pending or threatened (or any basis therefor
known to the Company) involving the prior employment of employees of the Company
and the use in any of the Company's business of any information or techniques
allegedly proprietary to any of their former employers.

         4.05 Certain Agreements of Officers and Employees.

                  (a) To the best of the Company's knowledge and belief, after
         due inquiry, no employee of the Company is in violation of any material
         term of any employment contract, patent disclosure agreement,
         non-competition agreement, or any other contract or agreement or any
         restrictive covenant relating to the right of any such officer or
         employee to be employed by the Company because of the nature of the
         business conducted by the Company or relating to the use of trade
         secrets or proprietary information of others, and to the best of the
         Company's knowledge and belief, the continued employment of the
         Company's officers and employees do not subject the Company or the
         Purchasers to any liability arising from such agreements.


                                      -8-
<PAGE>   9
                  (b) To the Company's knowledge, no officers of the Company,
         nor any Key Employees of the Company whose termination, either
         individually or in the aggregate, would have a material adverse effect
         on the Company, has any present intention of terminating his employment
         with the Company.

                  (c) The Company is not a party to any collective bargaining
         agreement and, to the best of its knowledge, after due inquiry, there
         have been no pending labor problems involving collective disputes or
         disturbances with any group of employees and, to the knowledge of the
         Company, there have been no attempts to organize its employees by any
         union or similar association.

         4.06 Compliance with Other Instruments. The Company is in compliance in
all respects with the terms and provisions of this Agreement and of its charter
documents, as amended, and by-laws, as amended, and in all material respects
with the terms and provisions of each material mortgage, indenture, lease,
agreement and other instrument relating to obligations of the Company, and, to
the best of the Company's knowledge, of all material judgments, decrees,
governmental orders, statutes, rules or regulations by which it is bound or to
which its properties or assets are subject. Neither the execution and delivery
of this Agreement or the Purchased Shares, nor the consummation of any
transaction contemplated hereby or thereby, has constituted or resulted in or
will constitute or result (with or without the giving of notice or passage of
time) in a default or violation of any material term or provision in any of the
foregoing documents or instruments.

         4.07 Federal Reserve Regulations. The Company is not engaged in the
business of extending credit for the purpose of purchasing or carrying margin
securities (within the meaning of Regulation G of the Board of Governors of the
Federal Reserve System), and no part of the proceeds of the Purchased Shares
will be used to purchase or carry any margin security or to extend credit to
others for the purpose of purchasing or carrying any margin security or in any
other manner which would involve a violation of any of the regulations of the
Board of Governors of the Federal Reserve System.

         4.08 Title to Assets. The company has good and marketable title in fee
to such of its fixed assets as are real property, and good title to all of its
other assets now carried on its books, including those reflected in the most
recent balance sheet of the Company described below in Section 4.10, or acquired
since the date of such balance sheet (except personal property disposed of since
said date in the ordinary course of business) free of any mortgages, pledges,
charges, liens, security interests or other encumbrances, except those indicated
in Exhibit 4.08 hereto and except for liens for current taxes not yet due and
payable and minor imperfections of title, if any, not material in nature or
amount and not materially detracting from the value or impairing the use of the
property subject thereto or impairing the operations of the Company. The Company
enjoys peaceful and undisturbed possession under all leases under which it is
operating and is in compliance in all material respects with all such leases,
and all said leases are valid and subsisting and in full force and effect.

         4.09 Patents and Intellectual Property Rights. The Company owns or has
a valid right, or will be able to obtain at reasonable cost standard in the
industry the right, to use the patents, patent rights, licenses, trade secrets,
trademarks, trademark rights, trade names or trade name rights or franchises,
copyrights, inventions, and intellectual property rights material to the conduct
of its businesses as now operated (the "Company's Intellectual Property"); and
no claim is pending to the effect that the operations of the Company, and to the
Company's knowledge, the operations of the Company will not, conflict with valid
patents, patent rights, licenses, trade secrets, trademarks, trademark rights,
trade names or trade name rights or franchises, copyrights, inventions, and


                                      -9-

intellectual property rights of others. Except as set forth in Exhibit 4.09
hereto, and except for the payment of the customary fees for the right to use
commercially available software, the Company has no obligation to compensate any
Person for the use of any of the Company's Intellectual Property and has granted
to no Person any license or other rights to use in any manner any of the
Company's Intellectual Property, whether requiring the payment of royalties or
not.

the audited balance sheet of the Company as of December 31, 1998 and the related
audited statements of income and statement of cash flows of the Company for the
twelve month period ended December 31, 1998 and the statement of changes in
redeemable preferred stock and stockholders' equity for the period ended

         business of the Company;

                  (d) Any waiver or compromise by the Company of a valuable
         right or of a material debt owed to it;

         or any of its Subsidiaries that any Purchaser may from time to time
         reasonably request.

         5.03 Confidentiality. Any confidential information obtained by any
holder of the Purchased Shares or Conversion Shares pursuant to this Agreement
shall be treated as confidential and shall not be disclosed to a third party
without the prior written consent of the Company, except that any Purchaser


                                      -17-
<PAGE>   18
may disclose such information to its investment advisers, attorneys,
accountants, consultants and other professionals to the extent necessary to
obtain their services in connection with such Purchaser's investment in the
Company, and to its officers, directors, shareholders and/or partners, and
except further that such information shall not be deemed confidential for the
purpose of enforcement of this Agreement or valuation of the Purchased Shares or
Conversion Shares and said information shall not be deemed confidential after it
becomes publicly known through no fault of the recipient. Notwithstanding the
foregoing, a holder of Purchased Shares shall be authorized to disclose
confidential information of the Company pursuant to the requirement or request
of a governmental body with jurisdiction, to the extent such disclosure is
required by a valid and applicable statute, rule, regulation, order, decree,
judgment or similar act, and notice is given by such holder of Purchased Shares
to the Company of any such requirement or request, which notice is adequate to
enable the Company to seasonably seek an appropriate protective order or
exemption from such requirement or request. Notwithstanding the foregoing, a
holder of Purchased Shares may disclose confidential information of the Company
to a governmental regulatory authority having jurisdiction over such holder
incident to an investigation or examination of such holder's affairs by such
regulatory authority, without providing the notice to the Company required by
the preceding sentence, in circumstances where such notice cannot practicably be
provided.

         5.04 Reserve for Conversion Shares. The Company shall at all times
reserve and keep available out of its authorized but unissued shares of Common
Stock, for the purpose of effecting the conversion of the Purchased Shares and
otherwise complying with the terms of this Agreement, such number of its duly
authorized shares of Common Stock as shall be sufficient to effect the
conversion of the Purchased Shares from time to time outstanding or otherwise to
comply with the terms of this Agreement. If at any time the number of authorized
but unissued shares of Common Stock shall not be sufficient to effect the
conversion of the Purchased Shares or otherwise to comply with the terms of this
Agreement, the Company will forthwith take such corporate action as may be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purposes. The Company will
obtain any authorization, consent, approval or other action by or make any
filing with any court or administrative body that may be required under
applicable state securities laws in connection with the issuance of shares of
Common Stock upon conversion of the Purchased Shares.

         5.05 Small Business Administration Matters.

                  (a) The proceeds from the issuance and sale of the Series F
         Preferred Stock will be used by the Company for working capital and
         other general corporate purposes, which may include, without
         limitation, one or more of the following as determined by the Company
         in its sole discretion: administration, marketing obtaining capital and
         other equipment and sales. The Company will provide to each Investor
         identified as a licensed Small Business Investment Company on Exhibit
         5.05 hereto (each an "SBIC Investor"), and to the Small Business
         Administration (the "SBA"), reasonable access to the Company's books
         and records for the purpose of confirming the use of proceeds by the
         Company.

                  (b) For a period of one (1) year following the Closing, the
         Company will not change the nature of its business activity if such
         change would render the Company "ineligible" as provided in Section
         107.720 of Title 13 of the Code of Federal Regulations (the "Federal
         Regulations").


                                      -18-
<PAGE>   19
                  (c) So long as any SBIC Investor holds any securities of the
         Company, the Company will at all times comply with the
         non-discrimination requirements of Sections 112, 113 and 117 of Title
         13 of the Federal Regulations.

                  (d) The Company will promptly provide each SBIC Investor who
         so requests in writing to the Company, specifying in such written
         request the nature of such required information in reasonable detail,
         such information as such SBIC Investor requests, in order to permit
         such SBIC Investor to comply with such SBIC Investor's obligations
         under the Small Business Act of 1958, as amended (the "Small Business
         Act"), and the regulations promulgated thereunder and related thereto.
         Any submission of financial information pursuant to this Section 5.05
         shall be under cover of a certificate executed by the Company's
         President, Chief Executive Officer, Chief Financial Officer or
         Treasurer, certifying that such information (i) relates to the Company,
         (ii) to the best of the Company's knowledge is accurate and (iii) if
         applicable, has been audited by the Company's independent auditors.

                  (e) For purposes of this Agreement, a "Regulatory Problem"
         means any set of facts or circumstances wherein both (i) it has been
         asserted by any governmental regulatory agency with jurisdiction over
         an SBIC Investor that such SBIC Investor is not entitled to hold, or
         exercise any significant right with respect to equity securities of the
         Company, including the Series A Preferred Stock or the currently
         unissued Common Stock of the Company into which the Series A Preferred
         Stock is convertible and (ii) such SBIC Investor reasonably determines
         that such assertion is meritorious and that the solutions proposed by
         such SBIC Investor are necessary to cure such regulatory violation by
         such SBIC Investor. If an SBIC Investor determines that it has a
         Regulatory Problem, it will so notify the Company and the other
         Investors as soon as practicable in writing. After giving such notice,
         such SBIC Investor will have the right to transfer its Series F
         Preferred Stock, and/or the shares of Common Stock issuable upon
         conversion of such Series F Preferred Stock, without regard to any
         restrictions on transfer set forth in this Agreement or any other
         agreement identified herien (collectively, the "Related Agreements") or
         in the Company's Certificate of Incorporation or Bylaws, other than
         restrictions related to securities laws, provided that the transferee
         agrees to become a party to this Agreement and/or to such relevant
         Related Agreements, and acknowledges that such securities will become
         again, after such transfer to such transferee, bound by all then
         relevant provisions relating to further transfer thereof by transferee,
         and the Company will take all such actions as are reasonably requested
         by such SBIC Investor in order to (i) effectuate and facilitate any
         transfer by such SBIC Investor of any securities of the Company then
         held by such SBIC Investor to any person designated by such SBIC
         Investor, (ii) permit such SBIC Investor (or any of its affilites) to
         exchange all or any portion of any voting security of the Company then
         held by such SBIC Investor on a share-for-share basis for shares of a
         nonvoting security of the Company as will be created by action of the
         Board, and, to the extent required by law, its stockholders, which
         nonvoting security will be identical in all respects to the voting
         security exchanged for it, except that it will be nonvoting and will be
         convertible into a voting security on such terms, solely as required to
         allow such SBIC Investor to comply with then-applicable regulatory
         considerations, as are requested by such SBIC Investor in good faith,
         and (iii) amend, and use its reasonable efforts to cause such other
         relevant parties, including without limitation, the Company's
         stockholders, to take such actions as are legally required in order to
         amend, this Agreement, the Related Agreements, the Company's
         Certificate of Incorporation, the Company's Bylaws and related
         agreements and instruments in order to effectuate and reflect the
         foregoing. The parties to this Agreement (other than the Company) will
         vote all of the Company's voting securities held by them, and will
         execute and deliver all


                                      -19-

         documents and instruments requested by them by the Company, in favor of
         and to effect such amendments and actions.

         6.01 No Waiver; Cumulative Remedies. No failure or delay on the part of
any Purchaser, or any other holder of the Purchased Shares or Conversion Shares

for this purpose all Purchased Shares as if converted to Conversion Shares) and
shall, in each such case, deliver copies of such consent in writing to any
holders who did not execute the same; provided, however, that no such consent
shall be effective to reduce the percentage of the consent of the holders of the
Conversion Shares which is required under this Section nor to affect or alter
the rights under Section 5.01(i) and 5.02 hereof of any Purchaser who purchases
at least 250,000 Purchased Shares at the Closing pursuant to this Agreement,
without the consent of such party (so long as it holds any Purchased Shares

satisfaction of conditions stated therein and any waiver or consent shall be

given.
