     This summary highlights selected information contained elsewhere in this
prospectus. This summary may not contain all of the information that you should
consider before investing in our common stock. You should read the entire
prospectus carefully, including "Risk Factors" and our financial statements and
the notes to those statements, before making an investment decision.
 
OUR BUSINESS
 
     We provide Internet market research systems specifically designed for
Internet advertisers, advertising agencies and Web publishers, and we recently
introduced a system for online retailers and consumer brand marketers. These
systems help enable our clients to effectively harness the power of the Internet
as an advertising, marketing and retailing medium. Our internally developed
systems, which our clients access through our Web site, combine our databases of
consumer lifestyle, product preference and demographic data with powerful
technology that enables our clients to perform queries and searches to plan
campaigns and strategies. Our syndicated Internet consumer research data is
collected, on an exclusive basis, by The Gallup Organization, Inc., from a
statistically representative group of approximately 40,000 active adult Web
users. We believe that our systems facilitate the purchase and sale of
advertising on the Internet and are becoming an important information tool in
enabling the increase in consumer electronic commerce.
 
     We introduced the @plan Gutenberg Advertising System in June 1997. As of
March 31, 1999 we had contracts representing a total of over 275 Internet
advertisers, advertising agency offices, Web sites, online retailers and
consumer brand marketers. We currently have subscription contracts for our
systems with all of the top 20 Web publishers as measured by advertising
revenue, 65% of the top 20 U.S. advertising agencies primarily focused on the
Web as measured by billings and 70% of the top 20 "traditional" U.S. advertising
agencies as measured by billings. We introduced the @plan Kepler E-Business
System in December 1998 and as of March 31, 1999 we had contracts with eight
online retailers and consumer brand marketers.
 
   
     A representative list of our clients includes Buy.com, CBS MarketWatch,
Grey Interactive, Modem Media.Poppe Tyson, Starcom IP (Leo Burnett),
TicketMaster Online, Time Inc. New Media and USWeb/CKS. We believe that our
systems have been accepted as a necessary tool by our clients as evidenced by
our 93% subscription contract renewal rate from our inception in May 1996
through March 31, 1999, although this renewal rate is based on a limited number
of contracts and may not be representative of future renewal rates. In addition,
the market for Internet market research tools for Internet advertisers,
advertising agencies, Web publishers, online retailers and consumer brand
marketers is new and rapidly evolving, and we expect competition in this market
to intensify in the future which could result in a decline in our renewal rate.
    
 
THE MARKET OPPORTUNITY
 
     Market research systems enable advertisers, marketers and retailers in many
industries to optimize their competitive strategies by providing them with
highly detailed consumer behavior information. The characteristics of the
Internet as both a unique medium for advertising and a distinct marketing and
sales channel plus the substantial potential size of the Internet market have
heightened the need among Internet advertisers, advertising agencies, Web
publishers, online retailers and consumer brand marketers for these tools. The
rapid growth of the number of users and the number of content and electronic
commerce sites on the Internet requires these online market participants to
recognize and adapt to changing
                                        4
<PAGE>   6
 
conditions more quickly than in many traditional media, marketing and retailing
worlds. The diversity of these users and sites requires online market
participants to process vast amounts of information to achieve an understanding
of their target market and the online market as a whole. In addition, the
competitive environment on the Internet for a particular retailing category may
be wholly different than that in the traditional marketplace, requiring online
market participants to develop new understandings of different and evolving
competitive factors. As a result, online market participants are seeking
trusted, third-party neutral market research systems that will enable them to
navigate the dynamic online marketplace.
 
   
     To meet the needs of online market participants and help enable the rise of
advertising and consumer electronic commerce on the Web, a provider of Internet
market research systems must be able to overcome challenges, including:
    
 
     - amassing and maintaining a large, statistically representative consumer
       research database;
 
     - developing a sophisticated yet user-friendly, Web-based software
       interface;
 
     - establishing rigorous, third-party neutral methods and procedures for the
       collection of data; and
 
     - identifying, researching and reporting emerging consumer electronic
       commerce trends.
 
OUR STRATEGY
 
     Our objective is to be the leading provider of market research systems for
online market participants including Internet advertisers, advertising agencies,
Web publishers, online retailers and consumer brand marketers. The following are
the key elements of our strategy:
 
     - Increase market penetration of the @plan Kepler E-Business System
 
     - Enhance and expand the @plan Gutenberg Advertising System
 
     - Develop additional revenue sources
 
     - Expand sales efforts and maximize sales effectiveness
 
     - Continue to provide the highest level of client service
 
     - Leverage our market research to identify key trends
 
     Our headquarters are located at Three Landmark Square, Suite 400, Stamford,
Connecticut 06901, and our telephone number is (203) 961-0340.

     Contract value represents the annualized value of all of our subscription
contracts outstanding at the end of each period. This value includes amounts
that we have previously recognized as revenue as well as amounts which we expect
to recognize as revenue over the remainder of a contract. As of March 31, 1999,
we have recognized $2.5 million of revenues of the $5.9 million in contract
value. Contract value is provided because we believe that it is useful
information for evaluating our future ability to generate revenues. Contract
value should not be construed as an alternative to revenue or deferred revenue,
or any other indicator of our future operating performance or liquidity.
Contract value is not a financial measure determined in accordance with
generally accepted accounting principles and may not be comparable to similarly
titled measures of other companies.

                                  RISK FACTORS
 
     You should consider carefully 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
 
BECAUSE WE HAVE A LIMITED OPERATING HISTORY, IT IS DIFFICULT TO EVALUATE OUR
BUSINESS      AND PROSPECTS
 
     We were incorporated in May 1996 and have a limited operating history. An
investor in our common stock must consider the risks and difficulties frequently
encountered by early stage companies in new and rapidly evolving markets,
including the Internet advertising and electronic commerce markets. These risks
include our ability to:
 
     - sustain revenue growth rates;
 
     - manage our expanding operations;
 
     - compete with companies that have longer operating histories, greater name
       recognition and greater financial resources; and
 
     - expand our current client base.
 
     We also depend on the growing use of the Internet for advertising, commerce
and communication, and on general economic conditions. We cannot assure you that
our business strategy will be successful or that we will successfully address
these risks. Please see "Management's Discussion and Analysis of Financial
Condition and Results of Operations" for detailed information on our limited
operating history.
 
WE HAVE A HISTORY OF LOSSES, AND WE ANTICIPATE CONTINUED LOSSES
 
     To date, we have not made a profit. We incurred net losses of approximately
$661,000 during our inception period from May 29, 1996 through December 31,
1996, $2.8 million in 1997, $1.9 million in 1998, and approximately $342,000 for
the three months ended March 31, 1999. As of March 31, 1999, our accumulated
deficit was $5.7 million. We expect to continue incurring significant operating
and net losses through at least 2000 and, as a result, we will need to generate
significant revenues to achieve and maintain profitability. Although our
revenues have grown in recent quarters, we cannot assure you that we will
achieve sufficient revenues for profitability. Even if we do achieve
profitability, we cannot assure you that we can sustain or increase
profitability on a quarterly or annual basis in the future. Our results of
operations and financial condition will be harmed if revenues grow more slowly
than we anticipate, or if operating expenses exceed our expectations and cannot
be adjusted accordingly. Please see "Management's Discussion and Analysis of
Financial Condition and Results of Operations" for detailed information on our
history of losses and anticipation of continued losses.
 
WE DEPEND ON SUBSCRIPTION RENEWALS BY OUR CLIENTS AND A DECREASE IN OUR
     CURRENT RATE OF RENEWAL COULD CAUSE A DECLINE IN OUR REVENUE
 
     We derive all of our revenues from subscriptions to our systems. Because we
have a limited operating history, our subscription renewal rate is based on a
limited
 
                                        8
<PAGE>   10
 
number of contracts and we are not sure that we will continue to experience our
current rate of subscription renewal. If our renewal rate percentage declines,
our results of operations and financial condition could be harmed. Our
subscription renewal rates may decline as a result of a consolidation in our
client base, the emergence of direct competition or if a significant number of
our clients cease operations.
 
OUR BUSINESS WILL BE HARMED IF OUR RELATIONSHIP WITH GALLUP IS TERMINATED
     CAUSING UPDATES TO OUR DATABASE OR THE INTRODUCTION OF NEW PRODUCTS TO BE
     DELAYED.
 
     The methodology for the collection of data, the generation of a sample
population to be surveyed and the collection of data from that sample population
for both our Web user database and our U.S. population database is controlled
and conducted by Gallup. Our agreement with Gallup extends through 2006. Gallup
does not have the right to terminate the agreement prior to 2006, however, other
circumstances beyond our control, such as Gallup going out of business or Gallup
breaching the agreement, could cause the agreement to terminate early. We cannot
be sure that Gallup will continue to provide us services in a manner that allows
us to execute our business strategy. If our agreement with Gallup terminates for
any reason, we will need to find another firm to perform our research data
collection services and this could harm our business by delaying our ability to
update our database and introduce new products.
 
IF GALLUP EXPERIENCES PROBLEMS WITH THE TIMELY COLLECTION, PROCESSING, STORING
     OR DELIVERY OF ACCURATE DATA, WE MAY LOSE CREDIBILITY WITH OUR CLIENTS
 
     The data that comprises our exclusively owned databases is collected and
statistically processed by Gallup and delivered to us on a quarterly basis.
Gallup could experience problems with, or make errors in, collecting,
processing, storing or delivering the data. In addition, Gallup could experience
problems with the computer systems that process and store the data. These
problems could result in inaccuracies in, or in delays in delivery or loss of,
the data from Gallup. These inaccuracies, delays or losses could cause us to
lose credibility with our clients or breach some client contracts which could
cause us to lose clients and could harm our business.
 
WE HAVE EXPERIENCED SIGNIFICANT GROWTH IN OUR BUSINESS IN RECENT PERIODS AND ANY
     INABILITY TO MANAGE THIS GROWTH AND ANY FUTURE GROWTH COULD HARM OUR
     BUSINESS
 
     We have grown and expect to continue to grow both by adding new products
and hiring new employees. This growth has placed, and our anticipated future
growth in our operations will continue to place a strain on our management
systems and resources. We cannot assure you that our management team will be
able to efficiently or successfully manage our growth. In addition, we will need
to hire additional financial and operations personnel. We expect that we will
need to continue to improve our financial and managerial controls and reporting
systems and procedures, and we will need to continue to expand, train and manage
our workforce.
 
                                        9
<PAGE>   11
 
IF WE ARE UNABLE TO ATTRACT AND RETAIN SALES AND CLIENT SERVICE PERSONNEL OR WE
    ARE UNABLE TO ADEQUATELY TRAIN OUR SALES PERSONNEL IN A TIMELY MANNER, OUR
    BUSINESS AND FUTURE REVENUE GROWTH WOULD BE HARMED
 
     Our business would be harmed if we were unable to continue to attract,
retain and motivate highly qualified, experienced sales and client service
personnel. We need to hire additional sales and client service personnel to
achieve our growth objectives. Competition for these individuals is intense.
Even if we are able to hire additional sales personnel it will take months of
training before they are fully productive. We may be unable to attract, train
and retain an adequate number of individuals to meet our sales and client
service objectives.
 
OUR BUSINESS AND FUTURE REVENUE GROWTH MAY SUFFER IF WE ARE NOT SUCCESSFUL AT
    DEVELOPING AND INTRODUCING NEW PRODUCTS
 
     Our future growth depends in part on our ability to offer new products and
services on a timely and cost-effective basis. Our business may suffer if we
fail to develop and introduce new products or if our new products are not
accepted by the market or are accepted at a slower rate than we anticipate. In
December 1998, we introduced the @plan Kepler E-Business System for online
retailers and consumer brand marketers. We are currently developing more
detailed market research systems for specific client groups. There are many
costs and risks associated with developing and introducing these and other new
products, including:
 
     - significant market research data collection and software development
       costs;
 
     - a need for additional sales, client service and other personnel;
 
     - diversion of management attention and resources; and
 
     - the lack of acceptance of new products in the marketplace.
 
     We cannot assure you that we will be successful in developing and
introducing new products.
 
OUR FUTURE REVENUES MAY BE UNPREDICTABLE AND OUR QUARTERLY RESULTS ARE EXPECTED
    TO FLUCTUATE AND IF WE FAIL TO MEET THE EXPECTATIONS OF PUBLIC MARKET
    ANALYSTS AND INVESTORS, THE MARKET PRICE OF OUR COMMON STOCK COULD DECLINE
 
     Our operating results have varied on a quarterly basis and may fluctuate
significantly in the future as a result of a variety of factors, many of which
are outside our control. Due to these fluctuations, it is likely that in some
future quarters our operating results will fall below the expectations of
securities analysts and investors, which could cause the price of our common
stock to drop. Factors that may affect our quarterly operating results include:
 
     - market acceptance of the Web as an advertising medium;
 
     - the development of the electronic commerce market;
 
     - market acceptance of our products;
 
     - the amount and timing of operating costs and capital expenditures
       relating to the expansion of our business, including those related to our
       planned development of more detailed market research and planning
       systems;
 
     - variations in product or client mix, as pricing may vary based on the
       volume and type of subscriptions being sold to a client;
 
                                       10
<PAGE>   12
 
     - our ability to expand our client base and retain current clients;
 
     - new competitors entering our market;
 
     - general economic conditions as well as economic conditions specific to
       the Internet;
 
     - our ability to attract, train and retain qualified sales and other
       personnel;
 
     - technical difficulties or service interruptions; and
 
     - the magnitude and timing of strategic pricing changes, marketing
       decisions or acquisitions.
 
     Our limited operating history and the emerging nature of our markets make
prediction of future revenues difficult. Our expense levels are based, in part,
on our expectations with regard to future revenues, and to a large extent our
expenses are fixed, particularly in the short term. We cannot assure you that we
will be able to predict our future revenues accurately and we may be unable to
adjust spending in a timely manner to compensate for any unexpected revenue
shortfall. Accordingly, any significant shortfall in our expectations could
cause significant declines in our quarterly operating results.
 
     Due to all the foregoing factors, our quarterly revenues and operating
results are difficult to forecast. We believe that our quarterly revenues,
expenses and operating results could vary significantly in the future, and that
period-to-period comparisons should not be relied upon as indicators of future
performance.
 
WE MAY EXPERIENCE CLIENT DISSATISFACTION OR BE EXPOSED TO LIABILITY FOR
     SUPPLYING INACCURATE INFORMATION TO OUR CLIENTS
 
     Our data may contain inaccuracies as a result of data collection or
software errors, among other reasons. Our clients may become dissatisfied with
our systems, or we may face liability if we supply inaccurate information. Any
client dissatisfaction with our data would hinder our ability to attract new
clients and retain existing clients. If we face liability for supplying
inaccurate data, our business may suffer.
 
OUR REPUTATION AND THE ATTRACTIVENESS OF OUR SYSTEMS COULD BE IMPAIRED BY A
     FAILURE OF OUR COMPUTING SYSTEMS AND OUR INTERNET SERVICE PROVIDER'S
     COMPUTING SYSTEMS
 
     The performance of our server and networking hardware and software
infrastructure is critical to our business, reputation and ability to attract
and retain clients. Any system failure that causes an interruption in service or
a decrease in responsiveness of our processing or data storage capabilities
could impair our reputation and the attractiveness of our products. We entered
into an agreement with UUNet for our Internet connectivity. Any interruption in
the service that UUNet provides, or any failure of UUNet to handle higher
volumes of Internet users, would harm our business.
 
     The availability of our systems is dependent upon our ability and the
ability of our Internet service provider to protect our server and network
infrastructure against damage from:
 
     - human error;
 
     - fire;
 
     - flood;
 
                                       11
<PAGE>   13
 
     - power loss;
 
     - telecommunications failure;
 
     - sabotage; and
 
     - intentional acts of vandalism.
 
     Despite precautions taken by us and our Internet service provider, the
occurrence of natural disasters or other unanticipated problems at our or their
facilities could result in interruption in the availability of our systems or
significant damage to our equipment. Even though we have implemented network
security measures, our servers are vulnerable to computer viruses, break-ins and
similar disruptions from unauthorized tampering. The occurrence of any of these
events could result in interruptions, delays, the loss or corruption of our data
or cessations in the availability of our systems, which could harm our business
and our reputation.
 
WE HAVE EXPERIENCED AND MAY AGAIN EXPERIENCE SYSTEM CAPACITY CONSTRAINTS THAT
     COULD RESULT IN CLIENT DISSATISFACTION OR A LOSS OF CLIENTS
 
     An increase in the number of our clients, the addition of new products or
spikes in client demand, either unexpected or in connection with new data
releases, could strain the capacity of our computer systems, which could lead to
slower response time or system failures. For example, some of our clients
recently experienced delays in accessing our systems due to increased client use
following the Spring 1999 update of our databases. Our business could be harmed
by system failures or slowdowns that reduce the speed and responsiveness of our
data processing and diminish the experience for our clients. We face risks
related to our ability to scale up to our expected client levels while
maintaining superior performance. We may need to purchase additional servers to
maintain adequate data processing speeds.
 
THE LOSS OF SERVICES OF OUR KEY EXECUTIVES WOULD LIKELY HURT OUR BUSINESS
 
     Our future success depends to a significant extent on the continued service
of Mark K. Wright, our Chief Executive Officer and Chairman of our Board of
Directors, and Karl A. Spangenberg, our President and Chief Operating Officer.
We have no employment agreements with either of these executives. The loss of
the services of either of Messrs. Wright or Spangenberg would likely hurt our
business. Please see "Management" for detailed information on these key
executives.
 
WE FACE COMPETITION FROM MORE ESTABLISHED PROVIDERS OF INTERNET MARKET
     RESEARCH TOOLS THAT COULD CAUSE A LOSS OF CLIENTS OR CAUSE US TO REDUCE THE
     PRICES WE CAN CHARGE TO OUR CLIENTS
 
     Our market, namely providing market research tools for Internet
advertisers, advertising agencies, Web publishers, online retailers and consumer
brand marketers, is new and rapidly evolving. Competition for clients is intense
and is expected to increase in the future as existing competitors develop new
solutions, potential competitors become active in the market and our industry
consolidates. We cannot assure you that we will be able to compete successfully
or that competitive pressures will not harm our business. We believe that our
ability to compete depends upon many factors both within and beyond our control,
including the following:
 
     - the timing and market acceptance of new products and enhancements to
       existing products developed either by us or our competitors;
 
                                       12
<PAGE>   14
 
     - our client service and support efforts;
 
     - our sales and marketing efforts; and
 
     - the ease of use, performance, price and reliability of products developed
       either by us or our competitors.
 
     Most of our competitors have longer operating histories, greater name
recognition, larger client bases and significantly greater financial, technical
and marketing resources than we do. This may allow them to respond more quickly
than we can to new or emerging technologies and changes in client requirements.
It may also allow them to devote greater resources than we can to the
development, promotion and sale of their products and services. These
competitors may also engage in more extensive research and development,
undertake more far-reaching marketing campaigns, adopt more aggressive pricing
policies and make more attractive offers to existing and potential employees,
strategic partners, advertisers and Web publishers. We cannot assure you that
our current and potential competitors will not develop products or services that
are of equal or superior quality to ours or that achieve greater market
acceptance or that may be offered at lower prices. 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 or services to address the needs of our prospective customers. It
is possible that new competitors may emerge and rapidly acquire significant
market share. Increased competition is likely to result in price reductions,
reduced gross margins and loss of market share, all of which will harm our
business. Please see "Business -- Competition for Our Internet Clients" for
detailed information about our competition.
 
YEAR 2000 PROBLEMS MAY DISRUPT OUR OPERATIONS AND LIMIT THE AVAILABILITY OF OUR
     SYSTEMS WHICH COULD RESULT IN LOST REVENUES, INCREASED OPERATING COSTS OR
     THE LOSS OF CLIENTS
 
     Many currently installed computer systems and software products are coded
to accept or recognize only two digit entries in the date code field. These
systems and software products will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, computer
systems and software may need to be upgraded to comply with Year 2000
requirements or risk system failure or miscalculations causing disruptions of
normal business activities. All of the systems on which we rely including our
systems, Gallup's systems and third-party systems such as those of UUNet, may
not be Year 2000 compliant, and we cannot assure you that all these systems will
be made Year 2000 compliant in a timely manner or that the third parties upon
which our business depends will achieve Year 2000 compliance. Any failure to fix
or replace our internally developed systems, Gallup's systems, or other
third-party software, hardware or services on a timely basis could result in
lost revenues, increased operating costs, the loss of clients, or other business
interruptions, any of which could harm our business, results of operations and
financial condition. Moreover, the failure to adequately address Year 2000
compliance issues in our internally developed systems could result in claims of
negligence, mismanagement, misrepresentation or breach of contract and related
litigation, which could be costly and time-consuming to defend. Please see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Year 2000 Compliance" for more detailed information.
 
                                       13
<PAGE>   15
 
ANY FAILURE BY US TO PROTECT OUR INTELLECTUAL PROPERTY COULD HARM OUR BUSINESS
     AND COMPETITIVE POSITION
 
   
     Our success and our competitive position are dependent on our internally
developed methods, technologies and trademarks which we generally protect
through a combination of copyright, trademark and trade secrecy laws,
confidentiality agreements with third parties, and license agreements with
consultants, vendors and customers. Despite these protections, a third party
could, without authorization, copy or otherwise take information from our
database. Our agreements with employees, consultants and others who participate
in development activities could be breached. We may not have adequate remedies
for any breach, and our trade secrets may otherwise become known or
independently developed by competitors. We have filed applications for several
trademarks in the United States. We cannot assure you that any of our trademark
applications will be approved. Even if these applications are approved, the
trademarks may be successfully challenged by others or invalidated. Please see
"Business -- Protection of Our Proprietary Rights" for more detailed
information.
    
 
WE MAY INFRINGE THE PROPRIETARY RIGHTS OF OTHERS AND BE LIABLE FOR SIGNIFICANT
     DAMAGES
 
     There have been substantial amounts of litigation in the computer and
online industries regarding intellectual property assets. Third parties may
claim infringement by us with respect to current and future products, trademarks
or other proprietary rights, or we may counterclaim against these parties. Any
claims or counterclaims could be time-consuming, result in costly litigation,
divert management's attention, cause product release delays, require us to
redesign our products or require us to enter into royalty or licensing
agreements, any of which could harm our business and operating results. Royalty
and licensing agreements, if required, may not be available on terms acceptable
to us, or at all.
 
WE RELY ON THIRD PARTIES FOR THE DEVELOPMENT OF SOME OF OUR SOFTWARE TECHNOLOGY
 
     We hire third parties to develop some of our software technology. We cannot
assure you that we will continue to receive this technology from third parties
or that this technology will continue to be available at a reasonable cost. If
we are unable to develop additional software or upgrade our existing software,
we may experience delays in making our current and future systems accessible to
our clients.
 
ANY FUTURE ACQUISITIONS OF BUSINESSES OR TECHNOLOGIES COULD STRAIN OUR
     MANAGERIAL, OPERATIONAL AND FINANCIAL RESOURCES
 
     We may acquire or make investments in complementary businesses, products,
services or technologies. We cannot assure you that we will be able to make such
acquisitions or investments on commercially acceptable terms. If we acquire a
company, we could have difficulty in assimilating that company's personnel and
operations. In addition, the key personnel of the acquired company may decide
not to work for us. If we make other types of acquisitions, we could have
difficulty in assimilating the acquired products, services or technologies into
our operations. These difficulties could disrupt our ongoing business, distract
our management and employees, increase our expenses and harm our results of
operations due to accounting requirements such as the amortization of goodwill.
Furthermore, we may incur debt or issue equity securities to pay for any future
acquisitions. The issuance of equity securities could be dilutive to our
existing shareholders.

RISKS RELATED TO OUR INDUSTRY
 
IF INTERNET USAGE DOES NOT CONTINUE TO GROW, WE WILL NOT BE SUCCESSFUL
 
     Our business would be adversely affected if Internet usage does not
continue to grow rapidly. Internet usage may be inhibited for a number of
reasons, including:
 
     - inadequate network infrastructure;
 
     - security concerns;
 
     - inconsistent quality of service; or
 
     - lack of availability of cost-effective, high-speed service.
 
     Even if Internet usage grows, the Internet infrastructure may not be able
to support the demands placed on it by this growth. As a result, its performance
and reliability may decline. Even if the necessary infrastructure or
technologies are developed, we may have to adapt our systems accordingly. In
addition, Web sites and proprietary online services have experienced
interruptions in their service as a result of outages and other delays occurring
throughout their infrastructure. If these outages or delays frequently occur in
the future, Internet usage could grow more slowly or decline.
 
OUR LONG-TERM SUCCESS DEPENDS ON THE DEVELOPMENT OF THE ELECTRONIC COMMERCE
     MARKET
 
     If electronic commerce does not grow or grows more slowly than expected,
our business will suffer. Our long-term success depends on widespread market
acceptance of electronic commerce. A number of factors could prevent this
acceptance, including the following:
 
     - electronic commerce is at an early stage and buyers may be unwilling to
       shift their purchasing from traditional vendors to online vendors;
 
     - the necessary network infrastructure for substantial growth in usage of
       the Internet may not be adequately developed;
 
     - increased government regulation or taxation may adversely affect the
       viability of electronic commerce;
 
     - increases in the cost of telecommunications services could make access to
       the Internet prohibitively expensive for consumers;
 
     - insufficient availability of telecommunication services or changes in
       telecommunication services could result in slower response times; and
 
     - adverse publicity and consumer concern about the security of electronic
       commerce transactions could discourage its acceptance and growth.
 
WE WILL LOSE CLIENTS OR FAIL TO ATTRACT NEW CLIENTS IF THE INTERNET DOES NOT
     CONTINUE TO DEVELOP AS AN ADVERTISING MEDIUM
 
     Our future success depends on an increase in the use of the Internet as an
advertising medium. We would lose clients or fail to attract new clients if the
market for Internet advertising fails to develop or develops more slowly than we
expect. The Internet advertising market is new and rapidly evolving, and it
cannot yet be compared with traditional advertising media to gauge its
effectiveness and value to advertisers. As a result, demand and market
acceptance for our systems is uncertain. Many of our current or potential
clients have little or no experience using the
 
                                       15
<PAGE>   17
 
Internet for advertising purposes, and they have allocated only a limited
portion of their advertising budgets to Internet advertising. The adoption of
Internet advertising, particularly by those entities that have historically
relied upon traditional media for advertising, requires accepting a new way of
conducting business, exchanging information and advertising products and
services. Clients may find that Internet advertising is less effective for
promoting their products and services relative to traditional advertising media.
In addition, most of our current and potential Web publisher clients have little
or no experience in generating revenues from the sale of advertising space on

THE INTERNET MARKET RESEARCH INDUSTRY IS NEW AND CHANGING QUICKLY AND OUR
     SYSTEMS MAY NOT BE ACCEPTED BY OUR EXISTING AND FUTURE CLIENTS
 
   
     To date, no industry consensus has emerged as to what information tools
will be essential to buying and selling Internet advertising as well as to the
development of electronic commerce. Our existing and future clients may
challenge or refuse to accept the market research information that our systems
provide. Our clients may not be satisfied with our methodology for data
collection or may feel that our databases do not represent Internet users. Our
clients might turn to other current or future providers of market research
systems.
    
 
THE FAILURE OF INDUSTRY INITIATIVES TO SUPPORT OUR METHODOLOGIES OR THEIR
     ENDORSEMENT OF OTHER METHODOLOGIES MAY RESULT IN A DECLINE IN SALES OF
     SUBSCRIPTIONS FOR OUR SYSTEMS
 
   
     Key industry organizations, including the Internet Advertising Bureau, the
Media Ratings Council, the Advertising Research Foundation and FAST Forward,
have begun initiatives focusing on standards for Internet market research and
audience measurement. To the extent that some or all of these trade groups do
not support our methodologies or endorse other methodologies, our business and
financial condition could be harmed.
    
 
TECHNOLOGICAL CHANGE MAY RENDER OUR SYSTEMS OBSOLETE
 
     The Internet, the Internet advertising and electronic commerce markets are
characterized by rapidly changing technologies, evolving industry standards,
frequent new product and service introductions, and changing client demands. Our
systems may be rendered obsolete by those developments. Our future success
depends on our ability to adapt to rapidly changing technologies, to enhance our
existing products and to develop and introduce a variety of new products to
address our clients' changing needs. We may experience difficulties that could
delay or prevent the successful design, development, introduction or marketing
of our products. In addition, our new products or enhancements must meet the
requirements of our current and prospective clients and must achieve significant
market acceptance. Delays in introducing new products and enhancements may cause
clients to forego purchases of our products and purchase those of our
competitors.
 
WE MAY BECOME SUBJECT TO GOVERNMENT REGULATION THAT COULD INCREASE THE COST OF
     PROVIDING OUR SYSTEMS
 
     Any new laws or regulations relating to the Web could increase the cost of
providing our systems and harm our financial condition. In particular, laws and
regulations may be adopted in the future that address the pricing of Internet
access.
 
                                       16

Several telecommunications companies have petitioned the Federal Communications
Commission to regulate Internet service providers and online service providers
in a manner similar to long distance telephone carriers and to impose access
fees on these companies. This could increase the cost of providing our systems
over the Internet.
 
RISKS RELATED TO THIS OFFERING
 
CURRENT SHAREHOLDERS, OFFICERS AND DIRECTORS OWN A LARGE AMOUNT OF OUR STOCK AND
     WILL BE ABLE TO CONTROL MATTERS REQUIRING SHAREHOLDER APPROVAL
 
     After this offering, the directors and executive officers and their
affiliates will beneficially own 79.0% of the outstanding common stock. They
will be able to exercise control over all matters requiring shareholder
approval, including the election of directors and approval of significant
corporate transactions. This concentration of ownership could deter, delay or
prevent transactions that could result in a change in control which could cause
the price at which our common stock trades to drop.
 
SUBSTANTIAL SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE
 
     After this offering, we will have 10,948,600 outstanding shares of common
stock. Sales of a substantial number of shares of common stock in the public
market following this offering could depress the market price of our common
stock. All the shares sold in this offering will be freely tradable. Assuming
the effectiveness of lock-up arrangements restricting the sale of common stock
for a period of 180 days between our shareholders or us and the underwriters,
8,441,400 of the 10,948,600 shares of common stock outstanding after this
offering will be available for sale in the public market 180 days following the
date of this prospectus. Of these shares, 8,324,400 shares will be subject to
volume limitations under federal securities laws. In addition, at such time,
2,076,940 shares subject to options and warrants currently outstanding will be
exercisable and may be resold.
 
     If our shareholders sell substantial amounts of common stock in the public
market, including shares issued upon the exercise of outstanding options and
warrants, the market price of our common stock could fall. Please see "Shares
Eligible for Future Sale" and "Underwriting" for an explanation of what could
happen if our shareholders sell substantial amounts of common stock.
 
WE EXPECT TO EXPERIENCE VOLATILITY IN OUR STOCK PRICE THAT COULD AFFECT THE
     VALUE OF YOUR INVESTMENT
 
     There has never been a public market for our common stock. Accordingly, we
cannot predict the extent to which investor interest in our common stock will
lead to the development of a trading market or how liquid that market might
become. The initial public offering price will be determined through
negotiations between representatives of the underwriters and us and may not be
indicative of prices that will prevail in the trading market. The price at which
our common stock will trade after this offering is likely to be highly volatile
as the stock market in general, and
 
                                       17
<PAGE>   19
 
the market for Internet-related and technology companies in particular, has been
highly volatile. Factors that could cause volatility may include, among other
things:
 
     - actual or anticipated variations in quarterly operating results;
 
     - announcements of technological innovations;
 
     - changes in financial estimates by securities analysts;
 
     - conditions or trends in the Internet industry;
 
     - changes in the market valuations of other Internet companies;
 
     - announcements by us or our competitors of significant acquisitions,
       strategic partnerships or joint ventures;
 
     - capital commitments;
 
     - additions or departures of key personnel; and
 
     - sales of common stock.
 
     Many of these factors are beyond our control. These factors may depress the
market price of our common stock, regardless of our operating performance. As a
result, investors may not be able to resell their shares of our common stock at
or above the initial offering price. The trading prices of many technology and
Internet-related companies' stocks have reflected valuations substantially above
historical levels. We cannot assure you that our stock will trade at the same
levels of other Internet stocks or that Internet stocks in general will sustain
their current market prices.
 
THE BROAD DISCRETION WE HAVE IN THE USE OF PROCEEDS OF THIS OFFERING MAY
    INCREASE THE RISK THAT WE WILL NOT USE THEM EFFECTIVELY OR THAT WE WILL USE
    THEM IN WAYS WITH WHICH YOU MAY NOT AGREE
 
     The net proceeds of this offering will be added to our working capital and
will be available for general corporate purposes, including expansion of sales,
marketing and customer service capabilities and product development. In
addition, we may use a portion of the net proceeds to acquire or invest in
complementary businesses, technologies, services or products. We cannot state
with certainty particular uses for the net proceeds from this offering. Our
management will have broad discretion in the use of the net proceeds. Please see
"Use of Proceeds."
 
A THIRD PARTY COULD BE PREVENTED FROM ACQUIRING YOUR SHARES OF STOCK AT A
    PREMIUM TO THE MARKET PRICE BECAUSE OF THE ANTI-TAKEOVER EFFECTS OF
    PROVISIONS IN OUR CHARTER, BYLAWS AND UNDER STATE LAW
 
     Our charter and bylaws provide for the establishment of a classified board
of directors, limitations on the ability of shareholders to call special
meetings, the lack of cumulative voting for directors and procedures for advance
notification of shareholder nominations and proposals. These charter and bylaw
provisions and provisions of Tennessee law could delay, deter or prevent a
change in control. After this offering our board of directors may issue up to
10,000,000 shares of preferred stock without any further vote or action by the
shareholders. The board can determine the price, rights, preferences, privileges
and restrictions, including voting rights, of those shares. The preferred stock
may be issued with voting, liquidation, dividend and other rights superior to
those of the common stock. The issuance of preferred stock could make it hard
for a third party to acquire a majority of our
 
                                       18
<PAGE>   20
 
outstanding voting stock. Please see "Description of Capital Stock" for more
information about material provisions of our charter, bylaws and Tennessee law.
 
INVESTORS IN THE OFFERING WILL INCUR DILUTION OF THEIR SHARES
 
     Investors purchasing shares of common stock in this offering will incur
immediate and substantial dilution in pro forma net tangible book value per
share. All of our outstanding options will be immediately exercisable and vested
upon the consummation of this offering. If these options are subsequently
exercised, there will be further dilution. Please see "Dilution" for an
explanation of the dilution investors will incur.
 
                           FORWARD LOOKING STATEMENTS
 
     There are statements under the captions "Prospectus Summary," "Risk
Factors," "Use of Proceeds," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business," and elsewhere in this
prospectus that are "forward-looking statements." These forward-looking
statements include, but are not limited to, statements about our plans,
objectives, expectations and intentions and other statements contained in this
prospectus that are not historical facts. When used in this prospectus, the
words "expect," "anticipate," "intend," "plan," "believe," "estimate" and
similar expressions are generally intended to identify forward-looking
statements. Because these forward-looking statements involve risks and
uncertainties, there are important factors that could cause actual results to
differ materially from those expressed or implied by these forward-looking
statements, including our plans, objectives, expectations and intentions and
other factors discussed under "Risk Factors."

<PAGE>   21
 
                                USE OF PROCEEDS
 
     We estimate that our net proceeds from the sale of the 2,500,000 shares of
common stock we are offering will be approximately $29.4 million, assuming an
initial public offering price of $13.00 per share and after deducting the
underwriting discounts and commissions and estimated offering expenses. If the
underwriters' over-allotment option is exercised in full, we estimate that our
net proceeds will be approximately $34.0 million, at an assumed initial public
offering price of $13.00 per share.
 
   
     We intend to use the net proceeds of this offering for general corporate
purposes, including working capital, an estimated $1.5 million over the next 12
months for the expansion of our sales, marketing and client service
capabilities, and an estimated $5.5 million over the next 12 months for product
development. In addition, we may use a portion of the net proceeds to acquire or
invest in complementary businesses, technologies, services or products; however,
we currently have no commitments or agreements and are not involved in any
negotiations with respect to any acquisition or investment. We cannot specify
with certainty the particular uses for the net proceeds to be received upon the
completion of this offering. Accordingly, our management team will have broad
discretion in applying the net proceeds.
    
 
     Pending such uses, we intend to invest the net proceeds of this offering in
short-term, interest-bearing, investment grade securities, certificates of
deposit or direct guaranteed obligations of the United States.
 
                                DIVIDEND POLICY
 
     We have never declared or paid any cash dividends. We do not expect to pay
any cash dividends on our capital stock in the foreseeable future. We currently
intend to retain future earnings, if any, to finance operations and the growth
of our business. We may incur indebtedness in the future which may prohibit or
effectively restrict the payment of dividends, although we have no current plans
to do so. Any future determination to pay cash dividends will be at the
discretion of our board of directors.

           deducting underwriting discounts and commissions and estimated
           offering expenses; and
 
        -  warrants to purchase 200,000 shares of common stock at an assumed

                                    DILUTION
 
     As of March 31, 1999, our pro forma net tangible book value after giving
effect to the conversion of our preferred stock was $3.6 million, or $0.43 per
share of common stock. Pro forma net tangible book value per share represents
the amount of our total tangible assets less total liabilities, divided by the
pro forma shares of common stock outstanding as of March 31, 1999. After giving
effect to the issuance and sale of the 2,500,000 shares of common stock offered
in this offering, and the application of the estimated net proceeds, our pro
forma net tangible book value as of March 31, 1999 would have been $33.0
million, or $3.02 per share. This represents an immediate increase in pro forma
net tangible book value of $2.59 per share to existing shareholders and an
immediate dilution of $9.98 per share to new investors. The following table
illustrates this per share dilution:

     The discussion and tables above assume no exercise of any stock options
outstanding as of March 31, 1999. As of March 31, 1999, there were options
outstanding to purchase a total of 1,852,740 shares of common stock with a
weighted average exercise price of $1.48 per share. If any of these options are
exercised, there will be further dilution to new investors. Please see

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     You should read the following discussion in conjunction with our financial
statements and the notes to those statements appearing elsewhere in this
prospectus.
 
OVERVIEW
 
     We were founded in May 1996. During the period from May 1996 to December
31, 1996, our inception period, we had no revenues and were primarily engaged in
the development and planning of our software and survey research
infrastructures. In June 1997, we introduced our first product system, the @plan
Gutenberg Advertising System. Since 1997, subscribers to this system have
included Internet advertisers, advertising agencies and Web publishers and, to a
lesser extent, online retailers and consumer brand marketers. During 1997, we
generated revenues of approximately $422,000, and continued to build our sales
and operations staff. During 1998, our first full year of sales, we continued to
grow our client subscriber base and generated revenues of $3.1 million. Despite
our growth in revenues, we incurred operating losses for the year, as our focus
continued to be on expanding our client and user bases, product development and
the hiring of additional sales, client service and operations personnel. During
1998, we opened a satellite office in San Francisco, California to service our
existing West Coast clients and to expand our client base in this market. In
December 1998, we introduced the @plan Kepler E-Business System specifically
designed for online retailers and consumer brand marketers.
 
     We derive all of our revenues from the sale of subscriptions to our
systems. The subscription contracts are generally non-cancelable for a period of
one year and most automatically renew unless we receive notice of termination
from the client prior to the anniversary date. Clients typically pay contract
fees on an annual, quarterly or monthly basis which are recorded as deferred
revenue until the revenue is recognized. Revenue is recognized on a straight
line basis beginning over the non-cancelable contract period, generally 12
months. Upon renewal, many of the subscription rates increase automatically in
accordance with contract provisions. These automatic increases are generally
higher in the first two renewal years than in subsequent renewal years where the
rate adjustment is based on increases in the Consumer Price Index, or CPI. We
have experienced a contract renewal rate of 93% from inception through March 31,
1999. The renewal rate is not necessarily indicative of the rate of future
retention of our revenue base. See "Risk Factors -- We depend on subscription
renewals by our clients and a decrease in our current rate of renewal could
cause a decline in our revenue."
 
     One measure of the volume of our business is "contract value" which
represents the annualized value of all contracts in effect at a given point in
time, without regard to the duration of contracts then outstanding and without
deducting revenue already recognized under these contracts. Our contract value
was $1.6 million at December 31, 1997, $4.6 million at December 31, 1998 and
$5.9 million at March 31, 1999. As of March 31, 1999, we have recognized $2.5
million of revenues of the $5.9 million in contract value.
 
     Our revenues and operating margins will fluctuate due, in part, to product
and customer mix. Annual subscriptions to the @plan Kepler E-Business System are
typically priced higher than annual subscriptions to the @plan Gutenberg Adver-
 
                                       24

tising System. Moreover, annual subscription pricing and renewal pricing are
often negotiated and may vary based on the volume of subscriptions being sold to
the client. Variations in product or client mix could cause our revenue and
operating results to fluctuate on a quarterly or annual basis.
 
     Product costs consist primarily of amounts paid to Gallup for quarterly
collection of data used in our market research systems. From time to time we
will engage Gallup on a case-by-case basis to collect additional data. In the
past, these additional engagements have caused our data collection costs to
fluctuate from quarter to quarter, and we expect quarterly data collection costs
to continue to fluctuate as we plan to continue to use Gallup for additional
data collection. Product costs will also increase as we collect data and incur
additional software development costs in conjunction with the development of new
products.
 
     Also included in product costs are software development costs which consist
primarily of the amortization of capitalized software development costs and, to
a lesser extent, other non-capitalized technology expenses such as Web site
maintenance. Software development costs represent direct expenses incurred to
improve or enhance our systems, including increasing access speeds, designing
new user interfaces and developing new system modules. As of March 31, 1999, we
had approximately $366,000 in capitalized software development costs which will
be amortized and expensed as product costs over the next one to three years. See
note 2 of the notes to our financial statements for an explanation of the
accounting for our software development costs.
 
   
     We have incurred significant losses since inception and as of March 31,
1999, we had an accumulated deficit of $5.7 million. Our net losses and
accumulated deficit resulted from our lack of substantial revenues and the
significant costs incurred in the development of our systems and in the
establishment of our operations infrastructure. We believe that our success will
depend largely on our ability to extend our leadership position as a source for
market research systems for the Internet. Accordingly, we intend to invest in
the development of new products, the enhancement of our current systems and in
the expansion of our sales force. As a result, we expect to incur additional
losses at least through December 31, 2000.
    
 
RESULTS OF OPERATIONS
 
THREE MONTHS ENDED MARCH 31, 1998 AND MARCH 31, 1999
 
     Revenues.  Total revenues increased from approximately $469,000 for the
three months ended March 31, 1998 to $1.3 million for the three months ended
March 31, 1999. The increase in revenues resulted principally from an increase
of approximately $501,000 in recurring revenues from the retention of existing
clients. Additionally, we experienced increased growth of approximately $367,000
in our subscription sales to new clients, including revenues from our Kepler
E-Business System launched in December 1998.
 
     Product Costs.  Product costs consist primarily of amounts paid to Gallup
for quarterly collection of data used in our market research systems and
software development costs. Product costs increased from approximately $408,000
for the three months ended March 31, 1998 to approximately $740,000 for the
three months ended March 31, 1999. This increase was due primarily to an
increase of approximately $217,000 in additional data collection costs and an
increase of
 
                                       25
<PAGE>   27
 
approximately $116,000 in software development costs associated with the
introduction of the @plan Kepler E-Business system. Our strategy includes the
development and introduction of new products. We are currently developing more
detailed market research systems for specific client groups. As a result, we
anticipate incurring increased data collection and software costs during the
remainder of 1999 and in future periods as we continue to develop additional
products.
 
     Selling and Marketing.  Selling and marketing costs consist primarily of
the personnel expenses associated with the sale and service of our systems,
including commissions, public relations costs and, to a lesser extent, marketing
expenses. Selling and marketing costs increased from approximately $295,000 for
the three months ended March 31, 1998 to approximately $539,000 for the three
months ended March 31, 1999. This increase was due largely to the expansion of
our sales force and client service team and commissions associated with
increased sales. Selling and marketing costs will increase as we continue to
expand our sales force and introduce new products.
 
     General and Administrative.  General and administrative expenses consist
primarily of salaries and related costs for our administrative, financial and
information technology personnel, professional fees, occupancy costs and general
office expenses. General and administrative expenses were approximately $182,000
for the three months ended March 31, 1998 as compared to approximately $433,000
for the three months ended March 31, 1999. This increase was primarily due to
the increase in personnel needed to support our expanding operations and related
costs. We anticipate hiring additional personnel and we will incur additional
costs related to being a public company, including directors' and officers'
liability insurance, investor relations programs and professional services fees.
Accordingly, general and administrative expenses will increase in future
periods.
 
     Interest income.  Interest income consists of interest on our cash and cash
equivalents. Interest income was approximately $53,000 for the three months
ended March 31, 1998 as compared to $37,000 for the three months ended March 31,
1999. The decrease in interest income was primarily attributable to the higher
cash balances during the three months ended March 31, 1998 as a result of net
proceeds from our sale of preferred stock in January 1998.
 
INCEPTION PERIOD AND YEARS ENDED DECEMBER 1997 AND 1998
 
     Revenues.  Total revenues increased from approximately $422,000 in 1997 to
$3.1 million in 1998. We had no revenues during our inception period from May
29, 1996 through December 31, 1996. The growth in revenues during 1998 resulted
principally from a $2.2 million increase in subscription sales for the @plan
Gutenberg Advertising System during our first full year of sales efforts, as
well as an approximate $455,000 increase in recurring revenues from the
retention of existing clients. We had nominal revenues from subscription sales
of the @plan Kepler E-Business System in 1998 as it was not introduced until
December 1998.
 
     Product Costs.  Product costs increased from approximately $487,000 in our
inception period to $1.7 million in 1997 due primarily to data collection costs
associated with the introduction of the @plan Gutenberg Advertising System in
June 1997. This increase was due primarily to an increase of approximately
$531,000 in additional data collection costs and an increase of approximately
$85,000 in
 
                                       26
<PAGE>   28
 
software development costs associated with the @plan Gutenberg Advertising
System and the launch of the @plan Kepler E-Business System.
 
     Selling and Marketing.  We had no selling and marketing costs during 1996
as the @plan Gutenberg Advertising System was not introduced until 1997. Selling
and marketing costs increased from approximately $819,000 in 1997 to $1.7
million in 1998. The increase was due largely to the expansion of our sales
force and client service team and commissions associated with increased sales.
 
     General and Administrative Expenses.  General and administrative expenses
were approximately $191,000 in our inception period, approximately $753,000 in
1997 and $1.1 million in 1998. The increase in each period was primarily
attributable to the increase in staffing levels to manage and support our
expanding operations.
 
     Interest Income.  Interest income was approximately $17,000 in our
inception period, approximately $80,000 in 1997 and approximately $192,000 in
1998. The increase in 1998 was primarily due to a higher investment balance as a
result of net proceeds of $5.1 million from our sale of preferred stock in 1998.

FACTORS AFFECTING QUARTERLY OPERATING RESULTS
 
     Our revenues increased during each quarter of 1998 and the first quarter of
1999. Quarterly revenue increased 35% from the first to the second quarter, 42%
from the second to the third quarter, 23% from the third to the fourth quarter
and 21% from the fourth quarter to the first quarter of 1999. These increases
were due to the growth in sales of subscriptions to the @plan Gutenberg
Advertising System, the effects of subscription renewals, which began in the
third quarter of 1998, and sales of the @plan Kepler E-Business System, which
was introduced in December 1998. These renewals reflect higher subscription
rates than those in place during the initial term of these contracts, in
accordance with contract provisions.
 
     Operating costs and expenses increased 45% from the first to the second
quarter, 9.3% from the second to the third quarter, 14% from the third to the
fourth quarter and increased 7.6% from the fourth quarter to the first quarter
of 1999. These increases were due primarily to additions of sales and
administrative personnel to sustain our growth and new product development
costs. Operating costs and expenses in the second quarter were impacted by
product development costs associated with our U.S. population data collection,
which was included with the @plan Kepler E-Business System beginning in the
fourth quarter. Loss from operations, in absolute dollars and as a percent of
revenues, decreased during the year due to increasing revenues from new
contracts and renewals and the maintenance of fixed expenses such as data
collection costs.
 
     Interest income remained relatively constant during the year but declined
as a percentage of revenues due to the growth in our revenues.
 
     Our operating results have varied on a quarterly basis and are expected to
fluctuate significantly in the future as a result of a variety of factors, many
of which are outside our control. Factors that may affect our quarterly
operating results include:
 
     - market acceptance of the Web as an advertising medium;
 
     - the development of the electronic commerce market;
 
     - market acceptance of our products and services;
 
   
     - the amount and timing of operating costs and capital expenditures
       relating to expansion of our business, including our planned development
       of more detailed market research systems;
    
 
     - variations in product or client mix, as pricing may vary based on the
       volume and type of subscription being sold to a client;
 
     - our ability to expand our customer base and retain current clients;
 
     - new competitors entering our market;
 
     - general economic conditions as well as economic conditions specific to
       the Internet;
 
     - our ability to attract and retain qualified sales and other personnel;
 
     - technical difficulties or service interruptions; and
 
     - strategic pricing changes, marketing decisions or acquisitions.
 
     Our limited operating history and the emerging nature of our markets make
prediction of future revenues difficult. Our expense levels are based, in part,
on our expectations with regard to future revenues, and to a large extent such
expenses are fixed, particularly in the short term. We cannot assure you that we
will be able to
 
                                       29
<PAGE>   31
 
predict our future revenue accurately and we may be unable to adjust spending in
a timely manner to compensate for any unexpected revenue shortfall. Accordingly,
any significant shortfall in our expectations could cause significant declines
in our quarterly operating results.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Since our inception, we have financed our operations primarily through the
private placement of preferred stock. Net proceeds from the sale of convertible
preferred stock from inception to March 31, 1999 have totaled $9.6 million. As
of March 31, 1999, we had $3.2 million in cash and cash equivalents.
 
     Net cash used in operating activities was approximately $570,000 in our
inception period, $2.8 million in 1997, $1.8 million in 1998 and approximately
$398,000 for the three months ended March 31, 1999. Cash used in operating
activities in each period was primarily attributable to net operating losses and
increases in accounts receivable which were partially offset by increases in
deferred revenue and accrued expenses.
 
     Deferred revenue increased from approximately $367,000 at December 31, 1997
to $1.1 million at December 31, 1998 and to $1.6 million at March 31, 1999.
Deferred revenue represents amounts invoiced under contract prior to our
rendering of services to the client. Unbilled accounts receivable increased from
approximately $91,000 at December 31, 1997 to approximately $245,000 at December
31, 1998, and decreased to approximately $241,000 at March 31, 1999. Unbilled
accounts receivable represents the value of services provided prior to
invoicing.
 
     Net cash used in investing activities was approximately $11,000 in our
inception period, $214,000 in 1997, $533,000 in 1998 and $127,000 for the three
months ended March 31, 1999. Cash used in investing activities in each period
was primarily attributable to software development costs and purchases of
property and equipment.
 
     Net cash provided by financing activities was $2.2 million in our inception
period, $2.3 million in 1997, $5.1 million in 1998 and $0 for the three months
ended March 31, 1999. Cash provided by financing activities in each period was
primarily attributable to the proceeds from the sale of preferred stock, net of
issuance costs.
 
     We believe that the net proceeds from this offering, together with our
existing cash and cash equivalents, will be sufficient to meet our working
capital and capital expenditure requirements for at least the 18 months
following this offering. Thereafter, we may be required to raise additional
funds. If additional funds are raised through the issuance of equity securities,
our shareholders may experience significant dilution. There can be no assurance
that additional funding, if needed, will be available on attractive terms, or at
all. If financing is not available when required or is not available on
acceptable terms, we may be unable to develop or enhance our products or
services. The failure to raise capital when needed could harm our business,
operating results and financial condition.
 
COMMITMENTS AND CONTINGENCIES
 
     During the first quarter of 1999, we issued 47,340 options to our
employees. These options had an exercise price that was approximately $8.67 less
per share than the fair market value of our common stock on the date of grant.
Accordingly, we
 
                                       30
<PAGE>   32
 
plan to recognize compensation expense of approximately $481,000 over the 48
month vesting period for these options. During the three months ended March 31,
1999, we recognized approximately $30,000 of this expense. However, as these
options will vest at the time of our initial public offering, we expect that we
will recognize the remaining $451,000 of expense during the second quarter of
1999.
 
     Simultaneous with the closing of this offering, Mark K. Wright, a director
and our Chief Executive Officer, Gary R. Haynes, a director, and each of the
preferred shareholders will receive warrants to purchase an aggregate number of
shares of common stock equal to 8% of the number of shares sold in this offering
at an exercise price equal to the initial public offering price. Of these
warrants, 12.5% will be granted to each of Messrs. Wright and Haynes. The
preferred shareholders, including Messrs. Wright and Haynes, will receive a pro
rata portion of the remaining 75% of the warrants. These warrants are
exercisable for seven years.
 
     We will account for these warrants at the time of issuance as follows:
 
     - For warrants issued to Messrs. Wright and Haynes, we will apply the
       provisions of Accounting Principles Boards Opinion No. 25, "Accounting
       for Stock Issued to Employees," and record compensation expense for the
       difference between the fair value of our common stock at the time of
       grant, based on our initial public offering price, and the exercise price
       of the warrant. As these amounts will be equivalent on the date of grant,
       we do not expect to record any compensation expense for these warrants.
 
     - For warrants issued to the holders of our preferred stock, we will record
       the value of these warrants, as determined by using the Black-Scholes
       model, as a dividend to these shareholders on the date of grant. This
       dividend will increase our accumulated deficit but will have no effect on
       reported net income (loss). While the actual value of the warrants issued
       to these shareholders cannot be determined until the date of grant, we
       estimate that the value of this dividend will approximate $1.2 million.
 
     We have no material commitments other than our lease for our corporate
headquarters and obligations under our agreement with Gallup. Our agreement with
Gallup provides us with initial baseline data and quarterly tracking data
collection. The agreement has a one-year term with nine successive one-year
renewals and is cancelable by us upon 90-days' written notice prior to an
anniversary date. The annual renewal provides for CPI increases to the
associated fees. Our strategy includes the development and introduction of new
products. We are currently developing more detailed market research systems for
specific client groups. As a result, we anticipate incurring increased data
collection and software costs during the remainder of 1999 and in future periods
as we continue to develop additional products.
 
YEAR 2000 COMPLIANCE
 
     Overview. Many currently installed computer systems and software products
are coded to accept or recognize only two digit entries in the date code field.
These systems and software products will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, computer
systems and software may need to be upgraded to comply with Year 2000
requirements or risk system failure or miscalculations causing disruptions of
normal business activities.
 
                                       31
<PAGE>   33
 
     State of Readiness. We have made a preliminary assessment of the Year 2000
readiness of all of our information technology systems, including the computer
hardware and software that support our systems and our financial and
administrative systems as well as our non-information technology systems such as
our office facilities. Our plan for addressing Year 2000 has three phases:
 
     - identification and evaluation of Year 2000 issues;
 
     - development of plans for addressing the issues and prioritization of
       those issues; and
 
     - implementation of plans and verification of the effectiveness of those
       plans.
 
   
     We do not have any contracts with external contractors to complete our Year
2000 compliance projects. In relation to our information technology systems, we
have reviewed the software obtained from third parties that is incorporated into
our products, and are seeking assurances from our vendors that licensed software
is Year 2000 compliant. In particular, we have received assurances from our
relational database provider, our operating system vendor and accounting systems
vendor that the programs are Year 2000 compliant. Further, we are in the process
of reviewing our internally developed software and are working with our third
party software developer to seek their assurance that their development and
backup systems are compliant. Additionally, we are in the process of reviewing
our Internet connectivity with UUNet as it relates to the delivery of our
products to our clients. We plan to have completed a full review of our
information technology systems by the end of the second quarter of 1999 and plan
to complete all testing by the end of the third quarter of 1999. We have not
reassigned or hired any employees to exclusively work on our Year 2000 review.
    
 
   
     Our non-information technology systems are currently being evaluated.
Preliminary responses from our lessor have indicated that our Stamford,
Connecticut facilities are compliant with respect to electrical and climate
control systems. Beginning in the second quarter of 1999 we plan to further
focus on our telecommunications equipment and voicemail systems. We have
identified other vendors whose Year 2000 compliance may have an impact on our
business, such as our payroll processing company. We are sending letters to our
other vendors requesting Year 2000 certification to ensure their Year 2000
compliance. We plan to conduct a Year 2000 simulation test by the end of the
third quarter of 1999 in order to complete our verification and testing of all
non-information technology systems and to assure the reliability of our risk and
cost estimates for our Year 2000 compliance. If any of these vendors cannot
become Year 2000 compliant, we could have systems failures, telecommunications
problems or electrical failures.
    
 
     We rely on Gallup for our data collection efforts. Gallup has advised us
that they are finalizing their Year 2000 compliance review of their systems and
are implementing any necessary hardware and software upgrades. Beginning in the
second quarter of 1999, we plan to request another letter from Gallup regarding
its Year 2000 efforts to enable us to reassess Gallup's compliance progress and
develop any necessary testing plans. We plan to establish a contingency plan in
the fourth quarter of 1999 after our simulation tests are complete.
 
     Costs. To date, we have not incurred any incremental costs in connection
with identifying, evaluating or addressing Year 2000 compliance issues. Most of
our expenses have related to, and are expected to continue to relate to, the
operating costs associated with time spent by employees in the evaluation
process and
 
                                       32
<PAGE>   34
 
Year 2000 compliance matters generally. At this time, we do not possess the
information necessary to estimate the potential costs of either revisions to our
systems, should revisions be required, or replacement of third-party software,
hardware or services that are determined not to be Year 2000 compliant. Although
we do not anticipate that such expenses will be material, these expenses, if
higher than anticipated, could harm our financial performance.
 
     Worst-Case Scenario. We believe that our most reasonably possible worst
case scenario would exist if Gallup's systems were subject to unexpected Year
2000 complications. This could potentially affect our ability to release timely
data in the first quarter or second quarter of 2000 depending on the nature of
the affected systems. If we determine that Gallup is unable to meet data
delivery requirements on a timely basis, we would ask Gallup to accelerate data
collection and data processing which may cause us to incur additional costs.
However, there can be no assurance that Gallup could collect and process data
under an accelerated schedule. We will continue to monitor this and any other
potential areas of exposure and develop contingency plans accordingly.
 
     Risks. We are not currently aware of any Year 2000 compliance problems
relating to our systems that would harm our business, results of operations and
financial condition, other than those previously discussed. We cannot assure you
that we will not discover Year 2000 compliance issues in our systems that will
require substantial revision. In addition, we can not assure you that
third-party software, hardware or services incorporated into our systems will
not need to be revised or replaced, all of which could be time consuming and
expensive.
 
     Our failure to fix or replace our internally developed systems or
third-party software, hardware or services on a timely basis could result in
lost revenues, increased operating costs, the loss of clients, or other business
interruptions, any of which could harm our business, results of operations and
financial condition. Moreover, the failure to adequately address Year 2000
compliance issues in our internally developed systems could result in claims of
mismanagement, misrepresentation or breach of contract and related litigation,
which could be costly and time-consuming to defend.
 
     In addition, there can be no assurance that governmental agencies, utility
companies, Internet access companies, third-party service providers and others
outside of our control will be Year 2000 compliant. The failure by such entities
to be Year 2000 compliant could result in a systemic failure beyond our control,
such as prolonged Internet, telecommunications or electrical failure. This could
prevent our users from accessing our system, which could harm our business,
results of operations and financial condition. Our contingency plan in this
event would be to provide data to our clients on a manual basis until our Year
2000 issues could be corrected.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1, "Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use." Statement of Position 98-1 is effective
for financial statements for years beginning after December 15, 1998. Statement
of Position 98-1 provides guidance over accounting for computer software
developed or obtained for internal use including the requirement to capitalize
specific costs and
 
                                       33
<PAGE>   35
 
amortization of such costs. We do not expect this standard to have a material
effect on our capitalization policy.
 
     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities." Statement of Position 98-5, which is effective for fiscal years
beginning after December 15, 1998, provides guidance on the reporting of
start-up costs and organization costs. It requires costs of start up activities
and organization costs to be expensed as incurred. The adoption of this standard
is not expected to have a significant impact on our results of operations,
financial position or cash flows.
 
     We do not believe that any other recent pronouncements will have a
significant impact on our results of operations, financial position or cash
flows.

                                    BUSINESS
OVERVIEW
 
     We provide Internet market research systems specifically designed for
Internet advertisers, advertising agencies and Web publishers, and we recently
introduced a system for online retailers and consumer brand marketers. These
systems help enable our clients to effectively harness the power of the Internet
as an advertising, marketing and retailing medium. Our internally developed
systems, which our clients access through our Web site, combine our databases of
consumer lifestyle, product preference and demographic data with powerful
technology that enables our clients to perform queries and searches to plan
campaigns and strategies. Our syndicated Internet consumer research data is
collected, on an exclusive basis, by Gallup from a statistically representative
group of approximately 40,000 active adult Web users. We believe that our
systems facilitate the purchase and sale of advertising on the Internet and are
becoming an important information tool in enabling the increase in consumer
electronic commerce.
 
     We introduced the @plan Gutenberg Advertising System in June 1997 and as of
March 31, 1999 we had contracts representing a total of over 275 Internet
advertisers, advertising agency offices, Web sites, online retailers and
consumer brand marketers. We currently have subscription contracts for our
systems with all of the top 20 Web publishers as measured by advertising
revenues, 65% of the top 20 U.S. advertising agencies primarily focused on the
Web as measured by billings and 70% of the top 20 "traditional" U.S. advertising
agencies as measured by billings. We introduced the @plan Kepler E-Business
System in December 1998 and as of March 31, 1999 we had contracts with eight
online retailers and consumer brand marketers.
 
BACKGROUND OF THE INTERNET INDUSTRY
 
     Growth of the Internet, Web Advertising and Online Commerce
 
   
     The Internet is rapidly emerging as a mass communications and commerce
medium enabling millions of people worldwide to share information, be
entertained, communicate and research or make consumer purchases electronically.
Based on industry sources, management believes that worldwide Internet usage
will grow from approximately 97 million users at the end of 1998 to 320 million
in 2002. This growth is driven by a number of factors, including an expanding
base of personal computers and other devices, more convenient, faster and
inexpensive access to the Internet and the increasing importance of the Internet
as a sales, marketing and distribution channel, communications medium and
information resource.
    
 
   
     The Internet is evolving into an important medium for advertisers due to
its interactive nature, its potential for highly targeted advertising and its
ability to reach a workplace audience. These unique characteristics, combined
with the growth in the number of Internet users and the compelling demographics
of these users, have led to a significant increase in Internet advertising.
Based on industry sources, management believes that expenditures on Internet
advertising in the United States will grow from $1.3 billion in 1998 to $10.4
billion in 2003.
    
 
     The Internet is increasingly affecting the methods by which businesses are
selling goods and services and developing relationships with their current and
potential customers. The Internet provides businesses with the ability to reach
a global audience, achieve greater economies of scale, and operate with minimal
 
                                       35
<PAGE>   37
 
   
infrastructure while providing consumers with a broad selection of goods and
services, increased pricing power and unparalleled convenience. In addition,
businesses that are not actively selling goods and services online are
integrating the Internet into their marketing strategy to acquire and retain
customers and enhance their marketing capabilities. Based on industry sources,
management believes that the value of goods and services purchased on the
Internet will increase from approximately $32 billion in 1998 to over $400
billion in 2002.
    
 
     Need for Internet Market Research Tools
 
     As the Internet advertising, marketing and retailing environment continues
to rapidly evolve, online market participants are continually challenged to
define and reach their target audiences, develop cost-efficient customer
acquisition and retention strategies and develop their business strategies and
tactics. Market research tools enable advertisers, marketers, and retailers in
many industries to optimize their competitive strategies by providing them with
highly detailed consumer behavior information.
 
     The characteristics of the Internet as both a unique medium for advertising
and a distinct marketing and sales channel plus the substantial potential size
of the Internet market have heightened the need among online market participants
for these tools. The rapid growth in the number of users as well as in the
number of content and electronic commerce sites on the Internet requires online
market participants to recognize and adapt to changing conditions more quickly
than in many traditional media, marketing and retailing environments. The
diversity of these users and sites requires online market participants to
process vast amounts of information to achieve an understanding of both their
target market and the online market as a whole. In addition, the competitive
environment on the Internet for a particular retailing category may be wholly
different than that in the traditional marketplace requiring online market
participants to develop new understandings of different and evolving competitive
factors.
 
     As a result, online market participants are seeking trusted, third-party
neutral Internet market research and planning tools that will enable them to
navigate the volatile and dynamic online marketplace. Each of these online
market participants has particular needs to successfully implement their online
strategy, including the following:
 
     Internet Advertisers and Advertising Agencies.  The Internet's unique
capability to provide advertisers with the ability to target users with specific
interests and characteristics, and in particular, hard to reach workplace users,
creates a need for Internet market research tools to inform and support those
targeting decisions. In addition, Internet advertisers and advertising agencies
are continually trying to define the role of the Internet in the total mix of
media to efficiently reach their target audience. In order to most effectively
incorporate Internet advertising into their overall marketing plans, advertisers
must have access to tools that enable them to understand the particular
strengths and weaknesses of the Internet in reaching their target audience.
 
     Web Publishers.  The market among sellers of Internet advertising is
becoming increasingly competitive as new advertiser-supported Web sites are
launched every day and existing advertiser supported Web sites seek to continue
their growth. New and existing Web publishers need Internet market research
tools to allow them to better understand their audiences in order to
differentiate themselves from
 
                                       36
<PAGE>   38
 
competing Web sites. To maximize their advertising revenues, Web publishers must
be able to optimize their sales efforts by identifying those potential
advertisers who would be interested in the audience their Web site can deliver.
Once these potential advertisers have been identified, Web publishers need to be
able to provide convincing, third-party neutral information to show that they
can deliver a specific advertiser's target audience and show how their site
differs from competitor sites as it relates to the specific needs of the
advertiser.
 
     Online Retailers and Consumer Brand Marketers.  As the number of retailers
and consumer brand marketers conducting business and marketing products and
services to consumers online continues to increase, the Internet has become a
highly competitive retail and marketing environment. Established businesses in
industries such as retailing and financial services must compete with online
companies in a dramatically different environment. In order to compete in this
environment, online retailers need Internet market research tools that will
enable them to develop cost-effective, highly targeted customer acquisition and
retention strategies. Both online retailers and consumer brand marketers need
Internet market research tools that will enable them to leverage the Internet to
target marketing relationships and promotional opportunities with their current
and potential customers.
 
     Challenges of Providing Internet Market Research Systems
 
     To meet the needs of online market participants and help enable the
increase in advertising and consumer electronic commerce on the Web, a provider
of Internet market research systems must be able to overcome many challenges,
including:
 
     - amassing and maintaining a large, statistically representative consumer
       research database in order to capture the complexity of the online space,
       the diversity of the online audience and the fragmentation of
       advertising, marketing and retailing competitors;
 
     - developing a sophisticated yet user-friendly, Web-based software
       interface that enables the user to efficiently process and analyze large
       amounts of discrete information to meet its own unique decision support
       and planning needs;
 
     - establishing rigorous, third-party neutral methodological and data
       collection procedures to ensure the accuracy and integrity of the
       information; and
 
     - identifying, researching and reporting emerging consumer electronic
       commerce trends.
 
     We believe that a significant opportunity exists for a company to provide
Internet market research tools that provide the type of detailed, third-party
neutral marketing research information that online market participants require.
By integrating a comprehensive and reliable database with sophisticated
workstation and decision support software, a Web-based system can enable online
market participants to make informed Internet advertising, marketing and
retailing decisions.
 
THE @PLAN SOLUTION
 
     Our Internet market research systems help enable our clients to effectively
harness the power of the Internet as an advertising, marketing and retailing
medium. Our internally developed systems, which our clients access through our
Web site, combine databases of consumer lifestyle, product preference and
demographic data
 
                                       37
<PAGE>   39
 
with powerful technology that enables our clients to perform queries and
searches to plan campaigns and strategies. Our syndicated Internet consumer
research data is collected, on an exclusive basis, by Gallup from a
statistically representative group of approximately 40,000 active adult Web
users. We believe that our systems facilitate the purchase and sale of
advertising on the Internet and are becoming an important information tool in
enabling the rise of consumer electronic commerce. We currently have
subscription contracts for the delivery of our services to all of the top 20 Web
publishers as measured by advertising revenues, 65% of the top 20 U.S.
advertising agencies primarily focused on the Web as measured by billings and
70% of the top 20 "traditional" U.S. advertising agencies as measured by
billings.
 
     We currently provide two Internet market research systems: the @plan
Gutenberg Advertising System for Internet advertisers, advertising agencies and
Web publishers and the @plan Kepler E-Business System for online retailers and
consumer brand marketers. Each of our systems provides reliable, third-party
neutral information.
 
     To Internet advertisers and advertising agencies, the @plan Gutenberg
Advertising System delivers Internet market research tools that help enable an
advertiser or advertising agency to:
 
     - assess the role the Web should play in achieving a client's specific
       advertising objectives;
 
     - determine the most efficient way to reach client defined audiences on the
       Web; and
 
     - make meaningful comparisons of the relative cost of reaching target
       audiences across a large number of advertiser supported Web sites.
 
     To Web publishers, the @plan Gutenberg Advertising System delivers Internet
market research tools that help enable a Web publisher to:
 
     - target its sales efforts by identifying its best brand and category
       prospects for advertising and sponsorship revenue;
 
     - access and compare the demographic lifestyle and product preference
       profiling information for other major advertiser-supported Web sites; and
 
     - obtain a comprehensive understanding of its users' interests and
       lifestyles to develop better positioning and content development
       strategies.
 
     To online retailers and consumer brand marketers, the @plan Kepler
E-Business System delivers Internet market research tools that help enable a
retailer or marketer to:
 
     - create sophisticated online retailing strategies by better understanding
       how shopping and purchase behaviors differ between the online and
       traditional retail environments for a variety of consumer product and
       service categories;
 
     - identify and assess the consumer lifestyle, product preference and
       demographic profiles of consumers shopping on competitors' Web sites;
 
     - develop cost-effective, highly-targeted customer acquisition and
       retention strategies; and
 
     - target marketing relationships and promotional opportunities with current
       and potential customers.

STRATEGY TO ACHIEVE THE @PLAN SOLUTION
 
     Our objective is to be the leading provider of Internet market research
systems for online market participants including Internet advertisers,
advertising agencies, Web publishers, online retailers and consumer brand
marketers. The following are the key elements of our strategy:
 
     Increase Market Penetration of the @plan Kepler E-Business System. We
intend to increase the market penetration of the @plan Kepler E-Business System
by continuing to target our sales and marketing efforts toward online retailers
and consumer brand marketers. We introduced the @plan Kepler E-Business System
in December 1998 and as of March 31, 1999 we had entered into contracts with
eight online retailers and consumer brand marketers. We intend to establish the
@plan Kepler E-Business System as the recognized leader in its market to
capitalize on the projected growth of electronic commerce.
 
     Enhance and Expand the @plan Gutenberg Advertising System. We intend to
expand our sales and marketing efforts of the @plan Gutenberg Advertising
System. Further, we intend to leverage our proprietary information and
technology to further enhance the @plan Gutenberg Advertising System and
facilitate the development of additional features. We believe that our
proprietary information and software interface and the experience and knowledge
gained through the delivery of our systems provide us with a significant
competitive advantage.
 
     Develop Additional Revenue Sources. We intend to leverage our database of
information, our technology, our expertise and our existing client base to
develop new sources of revenue. As the Internet continues to grow and evolve, we
believe the demand for more detailed Internet market research tools will
increase. We intend to meet this demand by continually developing new
information products that are of interest to our clients. In addition, we intend
to leverage our relationships with existing clients by expanding existing
contracts to include additional client offices and Web properties.
 
     Expand Sales Efforts and Maximize Sales Effectiveness. We believe that a
strong sales organization is essential to effectively sell our systems. Our
current sales team consists of highly qualified, experienced individuals who are
able to effectively sell our sophisticated systems. To increase our market
penetration, particularly in the growing electronic commerce segment, we intend
to continue to expand our sales efforts by rapidly expanding our sales team.
 
     Continue to Provide the Highest Level of Client Service. We emphasize high
quality service for our clients and take a proactive approach to ensure that our
clients are satisfied. We believe client satisfaction is the key to ensuring
high rates of contract renewal, and, accordingly, we maintain a dedicated client
service team that provides service, training and client support. We compensate
our client service managers in part based on targeted levels of renewal rates.
In addition, as our client base increases we intend to continue to build our
client service team to offer a high level of service, training and support.
 
     Leverage Our Market Research to Identify Key Trends. We believe that a
significant source of value to our clients is our ability to track trends in the
online marketplace. We continually update our data collection process to capture
relevant information to define these trends. We intend to continue to use and
refine these
 
                                       39
<PAGE>   41
 
tracking techniques to provide the information that our clients need and to
identify appropriate areas of expansion for our products.
 
OUR SYSTEMS
 
     We provide two Internet market research systems: the @plan Gutenberg
Advertising System for advertisers, advertising agencies and Web publishers and
the @plan Kepler E-Business System for online retailers and consumer brand
marketers. These systems are accessed through our Web site by entering a
password combination that allows our clients access to our sophisticated
software interfaces through which they can query various datasets in our
exclusively owned and controlled databases. The datasets and databases that new
clients can access generally depends on the system to which they subscribe as
set forth below:
 
                       @PLAN GUTENBERG ADVERTISING SYSTEM
- ------------------------------------------------
- - Advertiser-supported Web site specific profiling data
- - Web site advertising rate card, site description and contact information data,
  which we call our B.R.E.W. database
- - Web adult consumer lifestyle and product preference data
                         @PLAN KEPLER E-BUSINESS SYSTEM
- ------------------------------------------------
- - Electronic commerce/retailing Web site specific profiling data
- - Adult U.S. population lifestyle and product preference database
- - Web adult consumer lifestyle and product preference data
- - Advertiser-supported Web site-specific profiling data
 
     @plan Gutenberg Advertising System
 
     The @plan Gutenberg Advertising System is a comprehensive advertising
decision support and planning system providing lifestyle, product preference and
demographic profile information across a large number of advertiser-supported
Web sites.
 
     Internet advertisers and advertising agencies can query the system on an
interactive basis to better understand the role the Internet should play in
attaining specific advertising objectives. Clients can conduct queries on
various client defined targets, such as Web audiences, advertiser-supported Web
sites, or particular products or services. By combining the results of those
queries with current rate card information from our B.R.E.W. database, clients
can develop comprehensive and sophisticated media plans and marketing campaigns
for reaching a specific target audience in the most efficient and cost-effective
manner.
 
     Web publishers utilize the system to develop specific strategies for
optimizing their sales efforts toward those advertisers who would be most
interested in reaching the audience that the publisher's Web site can deliver.
The system provides the support for these optimization strategies and sales
efforts in the form of highly detailed, third-party neutral and comparable
lifestyle, product preference, shopping behavior and demographic profiling data
across a large number of advertiser supported Web sites. Web publishers can also
use the system to assess the strengths and weaknesses of their competitors as
well as to help differentiate the competitive position of their sites.

     @plan Kepler E-Business System
 
     The @plan Kepler E-Business System is a comprehensive consumer Internet
market research and planning system providing lifestyle, product preference,
shopping behavior and demographic profiling data across a large number of
advertiser-supported Web sites and consumer electronic commerce retail sites and
categories. Online retailers and consumer brand marketers utilize the system to
understand and track their competitive strengths and weaknesses in order to
assess their strategy in both traditional and online markets. The system
provides support for these assessments in the form of highly detailed and
comparable information across a large number of consumer electronic commerce
retail Web sites. Online retailers can also use this information to develop more
effective and cost-efficient customer acquisition and retention strategies. The
system also provides access to a database reflecting select lifestyle, product
preference and demographic profiling data for the total U.S. adult population.
Online retailers and consumer brand marketers utilize the system to access this
data to track differences in retailing trends between traditional and online
markets to better understand how the online market differs from the traditional
market in their particular retail category. Online retailers and consumer brand
marketers can also utilize the system to combine this profile information with
content site information to arrive at statistical estimates of the market
penetration for various products and services sold on the Internet.

     Following are examples of the manner in which our systems are used by
particular clients in each category. These case studies are not necessarily
representative of how our other clients may use our systems.
 
     Advertising Agency.
 
     Starcom IP
 
     Starcom IP, a division of Leo Burnett Company, Inc., is dedicated to
developing media strategies that build their clients' brands. To develop these
strategies effectively, they invest in a variety of media planning, buying and
research resources. Starcom IP subscribes to the @plan Gutenberg Advertising
System.
 
     Recently, a U.S. packaged goods company asked Starcom IP to help create a
targeted Web media plan for them. The client's target audience was men age 21
and older who are active sports enthusiasts. Starcom IP used the @plan Gutenberg
Advertising System to calculate which advertiser-supported Web sites would
efficiently deliver this target audience. Starcom IP then used the @plan system
to sort through the possible Web sites to be considered, arriving at a list of
Web sites for their recommended media plan. Once they completed the site
selection, Starcom IP used the @plan Gutenberg Advertising System to profile the
selected Web sites to ensure that the strengths of those sites fit the client's
specific needs.
 
     Web Publisher.
 
     The Mining Company
 
     The Mining Company is a network of more than 600 branded Web sites, each of
which is managed by a company-trained subject expert who offers visitors to
their Web site experienced guidance, altogether comprising more than 12,000
topics. The Mining Company subscribed to the @plan Gutenberg Advertising System
to understand what distinguishes their audience from the audiences of other
portals and community sites.
 
     When The Mining Company began conducting business on the Internet, they
faced a number of competitors for the advertising revenue they needed to support
their business. They needed to quickly identify the key areas of strength for
their product and develop a credible sales story that allowed them to position
their audience to the advertising buying community. The @plan Gutenberg
Advertising System provided The Mining Company's sales team with the consumer
lifestyle, product preference and demographic information that advertisers
demand. Based on the information generated by the @plan Gutenberg Advertising
System, The Mining Company positioned their audience as people who actively shop
and purchase online. This positioning provided the key point of differentiation
for their resulting sales and marketing effort.
 
     The Mining Company also used the @plan profiling tools to further identify
the relative strengths and weaknesses of their audience. From this analysis, The
Mining Company was able to develop a strategy to focus their sales efforts on
the areas with the strongest advertising sales potential. Information on the
strengths of their audience was combined with data on Web advertising
expenditures to establish priorities for the sales team to pursue.

     Online Retailer.
 
     TicketMaster Online
 
     TicketMaster Online-CitySearch, Inc. is a provider of local city guides,
local advertising and live event ticketing on the Internet, offering online
ticketing, merchandise, electronic coupons and other electronic commerce
transactions to a range of customers. TicketMaster subscribed to the @plan
Gutenberg Advertising System to obtain the consumer lifestyle, product
preference and demographic information they needed to manage, grow and expand
the scope of their new electronic commerce and advertising businesses.
 
     TicketMaster's traditional business is driven by four key consumer
ticketing segments: concerts, sports, family and theatre. TicketMaster's online
commerce activity was highly concentrated in the concert ticketing segment.
Using data generated by the @plan Gutenberg Advertising System, TicketMaster
determined that the primary reason for this was that the audience attracted to
their Web site fell within a narrow niche of 18-34 year olds who were single and
had lower incomes than the average Web user. To expand their audience and
commerce activity beyond this segment, TicketMaster used the @plan Gutenberg
Advertising System to identify the online behaviors for those Web users in each
of their other key segments. TicketMaster then used this information to help
develop specific marketing plans targeted to these consumers.
 
DATA COLLECTION AND RESULTING DATABASES
 
     We maintain statistically representative market research information
databases collected from approximately 40,000 active adult Web users. In
addition, information is collected from approximately 8,100 adult non-Web users
for use in our U.S. population database. The methodology for collecting our
data, the generation of a sample population to be surveyed and the collection of
data from that sample population for all of our databases is controlled and
conducted by Gallup, which uses a random scientific sample telephone dialing
process to generate an initial pool of potential survey participants. Data is
collected from the participants first on the phone and, for the Web user
database, by means of an extensive interactive online survey software program.
The survey software employs a "decision tree" methodology that automatically
poses specific questions based on a respondent's prior pattern of replies. The
online survey software can collect a wide variety of data while maintaining the
interest of the respondent because it automatically adjusts to the specific
behavior and interests of the respondent. For a subset of non-Web users,
consumer lifestyle, product preference and demographic data is collected by
means of an extensive phone interview. This data is used to create our U.S.
population database. The data collected is then incorporated into a number of
distinct datasets. These datasets include a U.S. consumer lifestyle and product
preference dataset, an electronic commerce/retailing Web site profile dataset,
an advertiser-supported Web site profiling dataset and a Web consumer lifestyle
and product preference dataset.
 
     We employ stringent controls to ensure the integrity of our consumer market
research data. Before any data point can be considered for reporting, it must
first pass rigorous statistical tests. In addition, we update the database every
three months by adding information collected from approximately 10,000 new
representative, active adult Web users while retiring the information collected
from the approximately 10,000 Web users that has been in our database the
longest. Our sample size
 
                                       43
<PAGE>   45
 
of approximately 40,000 active adult Web users exceeds that which is necessary
to provide a statistically reliable representation of Web behavior.
 
SALES AND MARKETING OF OUR SYSTEMS
 
     We sell our systems through a sales team located in Stamford, Connecticut
and San Francisco, California. Our current sales team consists of highly
qualified, experienced individuals who are able to effectively sell our
sophisticated systems. We intend to expand our sales team by adding additional
experienced individuals. Our sales team has a number of selling protocols and
systems in place to maximize prospecting and closing of subscription contracts.
Our systems are generally sold on an annual subscription basis. As of March 31,
1999, approximately 97% of our contracts provide for automatic one year renewals
unless the client provides written notice of termination prior to the
anniversary date of the contract.
 
     We take a highly selective approach to our marketing. To help build brand
awareness with our prospective customers, we largely rely on one-to-one live
product demonstrations of our systems. In addition, we seek speaking engagements
at very select events where current and prospective clients are concentrated. We
also produce marketing materials, including media kits and presentations, in
support of sales to prospective customers.
 
OUR CLIENT SERVICE TEAM
 
     We believe that our ability to establish and maintain long-term client
relationships and high contract renewal rates in part depends upon the strength
of our client service operations and team. Our client service team consists of
client service managers located in Stamford, Connecticut and San Francisco,
California. We motivate our client service managers to provide the highest
quality service by basing a portion of their compensation on both the renewal
rates of the clients they support and the overall client renewal rate. In
addition to providing training and client support, this group works proactively
with our clients to help them maximize the value they derive from our systems.
Each client service manager supports and is responsible for approximately 25-30
contracts. The assignments vary in relation to specific client needs but are
generally defined geographically to enhance opportunities for personal contact.
The client service managers are responsible for training their clients in how to
use the system and the research information that our systems provide, resolving
any problems their clients have with our systems, and providing strategic
insight and technical support. The client service managers also obtain feedback
from their clients to assist us in anticipating client needs and developing new
systems. We monitor our clients' use of the systems on a continual basis to
gauge client satisfaction. We intend to continue to build our client service
team as our client base increases to offer a high level of client service,
training and support.
 
TECHNOLOGY AND INFRASTRUCTURE
 
     One of our principal strengths is our internally developed technology,
which has been designed specifically for our Internet-based systems. Our
technology architecture features specially adapted capabilities to enhance
performance and reliability.
 
     Our systems run on a network of high-speed computers. The data is stored on
a redundant disk array which provides continuous service in the event of disk
failures. Current backup copies of the complete system are stored off site to
provide for data
 
                                       44
<PAGE>   46
 
recovery in the event of disaster. Real-time monitors alert our system
administrators to software and hardware failures and performance degradation 24
hours a day.
 
     Clients access our systems over the Web via a secure gateway to our Web
servers in Stamford, Connecticut. Our servers are linked to the Internet via a
digital circuit, which provides a scalable high bandwidth connection. We have in
place a temporary backup circuit which can be used in the event of failure of
our primary connection.
 
     Our databases are implemented atop a multi-tiered software architecture.
This architecture consists of relational database software, a Web server and our
exclusively owned and controlled applications. These applications employ special
purpose data access methods and algorithms to implement the analytic research
methodologies we developed in partnership with Gallup. Our software design is
the result of extensive research in relational database modeling, statistical
analysis and graphical user interfaces. All aspects of the software architecture
are designed to accommodate substantial growth of our client base.
 
     We believe that our future success will depend in part on our ability to
continue to maintain and enhance our systems and applications. To this end, we
intend to leverage the modular nature of our systems' architecture to enable us
to develop new applications rapidly. We expect that most enhancements to
existing and new systems and applications will be developed internally and
implemented using our outside suppliers of coding services. We believe that
timely development of new and enhanced applications and technology is necessary
to remain competitive in the marketplace. Accordingly, we intend to continue to
make investments in development and engineering.
 
DEVELOPMENT OF NEW PRODUCTS
 
     We believe that our future success depends on our ability to enhance our
current systems and continually develop new systems and products. Our executive
management takes an active role in the development of these enhancements and new
products. In December 1998, we introduced the @plan Kepler E-Business System.
Gallup assisted us in the development of methodology for the collection of
additional data for this system. We are internally developing more detailed
market research systems for specific client groups. We intend to capitalize on
our relationship with Gallup to gather the data necessary for these new systems.
For this additional data collection we will incur substantial expenses.
 
     We also intend to leverage our database of information, our technology, our
expertise and our existing client base to develop new information products of
interest to our clients. We continually track trends in the online marketplace
during our data collection efforts. We rely on our tracking techniques to assist
us in identifying appropriate areas of expansion for our products.
 
COMPETITION FOR OUR INTERNET CLIENTS
 
   
     The market for market research tools for Internet advertisers, advertising
agencies, Web publishers, online retailers and consumer brand marketers is new
and rapidly evolving, and we expect competition in this market to intensify in
the future. While we do not believe any of our competitors currently offer
Internet market research systems that provide the same search, query and
planning capabilities as our systems, we face competition from a number of
companies who provide services to a
    
 
                                       45
<PAGE>   47
 
   
similar base of clients and who could develop systems that more directly compete
with our systems. In some cases our services are complementary to services
provided by other companies and in some cases, particularly with respect to Web
"ratings" companies, our services are considered to be a substitute. Please see
"Risk Factors -- We face competition from more established providers of Internet
market research tools that could cause a loss of clients or cause us to reduce
the prices we can charge to our clients."
    
 
     Our competitors include:
 
   
     - Web "ratings" companies, including Media Metrix and Nielsen Media
       Research/NetRatings, that rely on using a sample group of respondents
       where software is installed on a respondent's computer and passively
       monitors Web behavior;
    
 
     - "auditing" companies, including I/PRO, that audit viewers in terms of
       page views, site impressions and navigation on a subject Web site;
 
     - advertisement targeting providers, including DoubleClick, 24/7 Media and
       NetGravity, that place advertisements on networks of Web sites and
       collect data on viewer response;
 
     - advertisement performance measurement companies, including MatchLogic;
 
     - Web advertising management services, including AdKnowledge;
 
     - online research and consulting providers, including Jupiter
       Communications; and
 
     - syndicated market research providers in traditional publishing, including
       MRI and Simmons.
 
     Most of these companies have greater financial, technical, product
development, marketing and other resources than we have. These companies may be
better known and have longer operating histories than we have. We believe that
our ability to compete depends on many factors both within and beyond our
control, including the following:
 
     - the timing and market acceptance of new solutions and enhancements to
       existing solutions developed by us or our competitors;
 
     - customer service and support efforts;
 
     - sales and marketing efforts; and
 
     - the ease of use, performance, price and reliability of solutions
       developed by us or our competitors.
 
PROTECTION OF OUR PROPRIETARY RIGHTS
 
     Proprietary rights are important to our success and our competitive
position. To protect our proprietary rights, we rely on copyright, trademark,
and trade secret laws, confidentiality agreements with third parties, and
license agreements with consultants, vendors and customers. Despite such
protection, a third party could, without authorization, copy or otherwise
appropriate information from our database. Our agreements with employees,
consultants and others who participate in development activities could be
breached. We may not have adequate remedies for any breach, and our trade
secrets may otherwise become known or independently developed by competitors. In
addition, the laws of some foreign countries do not
 
                                       46
<PAGE>   48
 
protect our proprietary rights to the same extent as do the laws of the United
States, and effective copyright, trademark and trade secret protection may not
be available in those jurisdictions.
 
     We have applied for registration of several trademarks in the United
States. None of these applications have been approved to date, and there can be
no assurance that the applications will be approved in the future. Even if these
applications are approved, the trademarks may be successfully challenged by
others or invalidated. If the applications are not approved because third
parties own the trademarks, the use of the trademarks will be restricted unless
we enter into arrangements with the third parties which may be unavailable on
commercially reasonable terms.
 
     There have been substantial amounts of litigation in the computer and
online industries regarding intellectual property assets. Third parties may
claim infringement by us with respect to current and future products,
trademarks, or other proprietary rights, or we may counterclaim against these
parties. Any such claims or counterclaims could be time-consuming, result in
costly litigation, divert management's attention, cause product release delays,
require us to redesign our products or require us to enter into royalty or
licensing agreements, any of which could harm our business, financial condition

BOARD COMMITTEES
 
     The board of directors recently created an audit committee and a

and procedures, the scope of the audit and will recommend the appointment of the
independent auditors. The members of the audit committee are Donald M. Johnston,

committee will evaluate and approve the compensation policies for the executive

DIRECTOR COMPENSATION
 
     Directors who are not our employees will receive an annual directors' fee
of $6,000 and directors' fees of $1,000 for each board meeting attended and $500
for each committee meeting attended. We will also reimburse directors for their
expenses incurred in connection with their activities as our directors.
Directors who are also our employees will receive no compensation for serving on
the board of directors.
 
     On March 11, 1999, we adopted our 1999 Stock Incentive Plan to attract and
retain the services of our key employees, consultants and non-employee members
of our board of directors. Each member of the board of directors who is not an
employee of ours, is not a former employee still receiving compensation for
prior services, other than benefits under a tax-qualified plan, and is not
currently receiving remuneration from us in any capacity other than as a
director will be eligible for the grant of stock options under the 1999 Plan.
Currently, all directors other than Mr. Wright are eligible to participate in
the 1999 Plan.
 
     Contingent upon the effectiveness of the registration statement relating to
this offering five directors will be granted options to purchase 25,000 shares
of our common stock at the initial offering price. These options vest
immediately upon grant. Additionally, upon the election of any new member of the
board of directors, that member will be granted an option to purchase 25,000
shares of common stock at the fair market value at the date of grant, vesting in
five equal annual installments beginning on the first anniversary of the date of
grant. Each year immediately following the date of our annual meeting, beginning
with the next annual meeting of our shareholders and provided that a sufficient
number of shares remain available under the 1999 Plan, there automatically will
be granted to each non-employee director who is then serving on the board an
option to purchase 3,000 shares of our common stock, which options will be
immediately vested. The options to be granted under the 1999 Plan will be
nonqualified stock options. Nonqualified stock options are stock options which
do not constitute "incentive stock options" within the meaning of Section 422A
of the Internal Revenue Code.
 
     Mark K. Wright, Gary R. Haynes and Roger J. Thomson, three of our
directors, are also holders of shares of our preferred stock. All holders of our
preferred stock,
 
                                       50

including these three directors, will be issued warrants to purchase shares of
our common stock upon consummation of this offering.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Before this offering, we did not have a compensation committee, and
compensation decisions were made by the full board of directors. Upon completion
of this offering, the compensation committee will make compensation
recommendations to the board of directors. No interlocking relationship exists
between the board of directors or compensation committee and the board of
directors or compensation committee of any other company, nor has any
interlocking relationship existed in the past.

                       OPTION GRANTS IN FISCAL YEAR 1998
 
     The following table sets forth information regarding stock options granted
during 1998 to the executive officers named in the Summary Compensation Table
above, including the potential realizable value over the 10 year term of the
options based on assumed rates of stock appreciation of 5% and 10%, compounded
annually. These assumed rates of appreciation comply with the rules of the SEC
and do not represent our estimate of future stock prices. Actual gains, if any,
on stock option exercises will be dependent on the future performance of our
common stock. In 1998, we granted options to acquire up to an aggregate of
349,200 shares to employees, consultants, directors and other persons having a
business relationship with us, all under the 1996 Plan and all at an exercise
price equal to not less than the fair market value of our common stock on the
date of grant as determined in good faith by the board of directors. Optionees
may pay the exercise price by check, note, delivery of already-owned shares of
our common stock or any other instrument the board will accept. Options under
the 1996 Plan will fully vest upon the completion of this offering.

     No options were exercised during 1998 by our Chief Executive Officer or any
other of our executive officers. The following table sets forth information
about the number and year-end value of exercisable and unexercisable options
held by the executive officers named in the Summary Compensation Table for the

$13.00 per share, minus the exercise price, multiplied by the number of shares
underlying the option. Under the terms of the 1996 Stock Option Plan, all of
these options become exercisable immediately upon the consummation of this

STOCK PLANS
 
     1996 Stock Option Plan.  We adopted the 1996 Stock Option Plan in July
1996, and it was amended and restated in August 1997 and January 1998. The
purpose of the plan is to attract, retain and reward directors, officers, key
employees and consultants by offering equity interests in our company. The plan
provides for grants of incentive stock options, within the meaning of Section
422A of the Internal Revenue Code of 1986, and non-qualified stock options. Our
board of directors and shareholders authorized a total of 1,980,000 shares of
common stock for issuance under this plan. Upon consummation of this offering,
no further awards of stock options will be granted under the 1996 plan.
 
     All options granted under this plan shall become immediately exercisable
and vested upon the closing of this offering. As of March 31, 1999, we have
granted options for the purchase of 1,852,740 shares of common stock to
employees, consultants, directors and other persons having a business
relationship with us.
 
   
     1999 Stock Incentive Plan.  Our board of directors adopted the 1999 Stock
Incentive Plan in March 1999 and it was approved by our shareholders in March
1999. The purpose of the plan is to attract, retain and reward key employees,
consultants and non-employee directors. This plan allows flexibility in the
award of stock based incentive compensation to these people. The plan provides
for grants of incentive stock options, non-qualified stock options, stock
appreciation rights, restricted stock, and other stock-based awards. To date
options to purchase 24,000 shares of common stock have been granted to new
employees under the 1999 plan at an exercise price equal to the initial offering
price. These options vest quarterly over a period of three years. In addition,
upon effectiveness of the registration statement relating to this offering, five
directors will be granted options to purchase 25,000 shares of our common stock
at the initial offering price. These options vest immediately upon grant.
    
 
                                       53
<PAGE>   55
 
     The plan authorizes up to 800,000 shares of common stock for issuance under
the plan plus an annual increase to be added on each anniversary date of the
adoption of this plan equal to the lesser of 400,000 shares, two percent of the
outstanding shares of our common stock on that anniversary date or a number
determined by our Board of Directors. However, no individual may receive options
to purchase more than 100,000 shares of common stock in any fiscal year.
Whenever a share of common stock underlying a stock option is no longer subject
to that option, that share of common stock shall again be available for
distribution under the plan.
 
     This plan will be administered by the compensation committee of the board
of directors. The compensation committee will have the authority to:
 
     - select the individuals who may receive the grant for the options;
 
     - determine the number of shares to be covered by each option or other
       awards to be granted; and
 
     - determine the terms and conditions of the option, including the share
       price, vesting schedule and any restrictions or limitations on the
       options.
 
     Grants under the plan may consist of options intended to qualify as
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended, non-qualified stock options that are not
intended to qualify, stock appreciation rights, restricted stock or other
stock-based awards. Grants can be made to any key employee, consultant and
non-employee director. Incentive stock options may only be granted to our
employees.
 
     The option price for each share of common stock underlying an incentive
stock option shall be at least 100% of the fair market value of the stock at the
date of grant. The option price for non-qualified stock options shall be at
least 85% of the fair market value of the underlying stock at the date of grant.
No incentive stock option shall be exercisable after 10 years from the date of
grant. Incentive stock options are not transferrable except to members of the
optionees' immediate family or by will or the laws of descent and distribution.
 
     If an optionee's employment terminates because of death, any option held by
the optionee may be exercised to the extent the option was exercisable at the
time of death. This exercise must occur within one year from the date of death
or until the term of the option expires, whichever is shorter.
 
     If an optionee's employment is terminated because of disability, any option
held by the optionee may be exercised to the extent the option was exercisable
at the time of the disability, unless accelerated by the committee. This
exercise must occur within three years from the date of the disability or until
the term of the option expires for non-qualified options and one year from the
date of disability or until the term of the option expires for incentive stock
options, whichever is shorter.
 
     If an optionee's employment terminates because of retirement, any option
held by the optionee may be exercised to the extent the option was exercisable
at the time of the retirement, unless accelerated by the committee. This
exercise must occur within three years from the date of the retirement or until
the term of the option expires for non-qualified options and three months from
the date of the retirement or until the term of the option expires for
investment stock options, whichever is shorter.

<PAGE>   56
 
     If an optionee's employment is involuntarily terminated without cause, as
that term is defined in the plan, any option held by the optionee may be
exercised to the extent the option was exercisable at the time of termination.
This exercise must occur before the earlier of three months from the date of
termination or the expiration of the option. The compensation committee may
extend the exercise period for six months or until the term of the option
expires whichever is shorter. However, any option that is not exercised within
three months will be treated as a non-qualified stock option.
 
     If an optionee voluntarily terminates employment, any option held by the
optionee may be exercised to the extent the option was exercisable at the time
of termination. This exercise must occur within three months from the date of
termination or until the term of the option expires, whichever is shorter. The
compensation committee may extend the exercise period for six months or until
the term of the option expires, whichever is shorter. However, any option that
is not exercised within three months will be treated as a non-qualified stock
option.
 
     Stock appreciation rights can be granted in connection with all or part of
any stock option granted. They will terminate and no longer be exercisable when
the related stock option terminates. They are only exercisable at the time and
to the extent that the stock options to which they relate are exercisable.
Shares of restricted stock can be issued alone, in addition to or with other
awards granted under the plan. The committee can place limitations on the sale
or transfer of the restricted stock. Other stock-based awards can be granted by
the committee in its discretion. For a description of awards to non-employee
directors, please see "Management -- Compensation of Directors."
 
     The compensation committee can adjust the number of shares reserved for
issuance under the plan if there is a merger, reorganization, consolidation,
recapitalization, extraordinary cash dividend, stock dividend, stock split or
other change in corporate structure. If there is a change in control, any
awarded option shall become fully exercisable and vested. This change of control
can occur if any person or entity acquires more than 50% of the voting power of
our capital stock or if our existing shareholders hold less than 50% of our
outstanding securities after a cash tender or exchange offer, merger or other
business combination, sale of assets or contested election.
 
SEVERANCE AGREEMENTS
 
     Upon consummation of this offering, we will enter into severance agreements
with our executive officers. These agreements provide for a severance payment to
the executive officer if, within six months of a change in control of our
business, the executive's:
 
     - job function is changed;
 
     - base salary is reduced;
 
     - office is relocated; or
 
     - employment is terminated, other than by death, disability, retirement or
       for cause.
 
This payment will be an amount equal to six months of the executive's current
base salary.

                          DESCRIPTION OF CAPITAL STOCK
 
     The following description of our capital stock and the provisions of our
charter and bylaws are only summaries and are qualified by reference to our
charter and bylaws filed as exhibits to the registration statement of which this
prospectus is a part. Our authorized capital stock consists of 50,000,000 shares
of common stock, no par value per share, and 10,000,000 shares of preferred
stock, no par value per share. As of March 31, 1999, there were 907,200 shares

shareholders, 2,016,000 shares of Series B convertible preferred stock
outstanding held of record by nine shareholders and 1,725,667 shares of Series C

offering.
 
COMMON STOCK
 
     Holders of the common stock are entitled to receive, when and if declared
by the board of directors, dividends and other distributions in cash, stock or
property from our assets or funds legally available for those purposes subject
to any dividend preferences that may be attributable to preferred stock. Holders
of common stock are entitled to one vote for each share held of record on all
matters on which shareholders may vote. Holders of common stock are not entitled
to cumulative voting for the election of directors.
 
     There are no preemptive, conversion, redemption or sinking fund provisions
applicable to the common stock. All outstanding shares of common stock are fully
paid and non-assessable. In the event of our liquidation, dissolution or winding
up, holders of common stock are entitled to share ratably in the assets
available for distribution.

outstanding. This number consists of 907,200 shares of common stock currently

stock upon consummation of the offering. After this conversion, our board of
directors, without further action by the shareholders, is authorized to issue an
aggregate of 10,000,000 shares of preferred stock. Currently, we have no plans
to issue a new series of preferred stock. Our board of directors may, without
shareholder approval, issue preferred stock with dividend rates, redemption
prices, preferences on liquidation or dissolution, conversion rights, voting
rights and any other preferences, which rights and preferences could adversely
affect the voting power of the holders of common stock. Issuance of preferred
stock could make it harder for a third party to acquire, or could discourage or
delay a third party from acquiring, a majority of our outstanding stock.
 
     The 4,189,667 shares of preferred stock currently outstanding have
preemptive rights.

REGISTRATION RIGHTS
 
     After the consummation of the offering, the holders of warrants to purchase
200,000 shares, 230,000 shares if the underwriters' over-allotment option is
exercised in full, of common stock or their transferees, and holders of
7,541,400 shares of common stock issuable upon conversion of the preferred stock
will have registration rights with respect to those securities. These rights are
described in a shareholders agreement between us and the holders of those
securities. The agreement provides for registration rights upon the demand of
the holders of at least 51% of the outstanding shares of our preferred stock. In
addition, pursuant to that agreement, the holders are entitled, subject to some
limitations, to require us to include their securities in future registration
statements we file under the Securities Act of 1933, referred to as piggyback
registration rights. The holders of those securities also are entitled, subject
to some limitations, to require us to register their securities on a
registration statement on Form S-3 once we are eligible to use a Form S-3 in
connection with registrations. However, holders of these shares will be
restricted from exercising these rights until 180 days after the date of this
prospectus. Registration of shares of common stock by the exercise of these
demand registration rights, piggyback registration rights or S-3 registration
rights under the Securities Act of 1933 would result in these shares becoming
freely tradable without restriction under the Securities Act of 1933 immediately
upon the effectiveness of such registration. Please see "Risk
Factors -- Substantial sales of our common stock may depress our stock price"
and "Shares Eligible for Future Sale."
 
CLASSIFIED BOARD OF DIRECTORS
 
     Immediately prior to the effectiveness of this offering, our board of
directors will be divided into three classes of directors serving staggered
three-year terms. As a result, approximately one-third of the board of directors
will be elected each year. This provision, along with the provision authorizing
the board of directors to fill vacant directorships or increase the size of the
board of directors, may deter a shareholder from removing incumbent directors
and gaining control of the board of directors by filling vacancies created by
the removal with its own nominees.
 
SHAREHOLDER ACTION; SPECIAL MEETING OF SHAREHOLDERS
 
     The charter that will become effective immediately prior to the
effectiveness of this offering states that shareholders may not take action by
written consent, but only at duly called annual or special meetings of
shareholders. The charter also provides that special meetings of shareholders
may be called only by the chairman of the board of directors or by a majority of
the board of directors.
 
ADVANCE NOTICE REQUIREMENTS FOR SHAREHOLDER PROPOSALS AND DIRECTOR NOMINATIONS
 
     The bylaws provide that shareholders must provide timely notice in writing
to bring business before an annual meeting of shareholders or to nominate
candidates for election as directors at an annual meeting of shareholders. To be
timely notice for an annual meeting, a shareholders's notice must be delivered
to or mailed and received at our principal executive officers at least 120 days
before the first anniversary of the date our notice of annual meeting was
provided for the previous year's annual meeting of shareholders. If no annual
meeting of shareholders was held in the previous year or the date of the annual
meeting of shareholders has been changed to be more than 30 calendar days
earlier than or 60 calendar days after that
 
                                       62
<PAGE>   64
 
anniversary, notice by the shareholder, to be timely, must be received at least
60 days but no more than 90 days before the annual meeting of shareholders or
the close of business on the 10th day following the date on which notice of the
date of the meeting is given to shareholders or made public, whichever first
occurs. To be timely notice for a special meeting, a shareholder's notice must
be delivered to us by the close of business 10 days after notice of the meeting
is given to shareholders. The bylaws also specify requirements as to the form
and content of a shareholders' notice. These provisions may keep shareholders
from bringing matters before an annual meeting of shareholders or from making
nominations for directors at an annual meeting of shareholders.
 
AUTHORIZED BUT UNISSUED SHARES
 
     The authorized but unissued shares of common stock and preferred stock are
available for future issuance without shareholder approval. These additional
shares may be used for a variety of corporate purposes, including future public
offerings to raise additional capital, corporate acquisitions and employee
benefit plans. The existence of authorized but unissued shares of common stock
and preferred stock could make it harder or discourage an attempt to obtain
control of us by a proxy contest, tender offer, merger or otherwise.
 
TENNESSEE ANTI-TAKEOVER LAW AND CHARTER AND BYLAW PROVISIONS THAT MAY HAVE AN
  ANTI-TAKEOVER EFFECT
 
     Provisions in our charter, bylaws and Tennessee law could make it harder
for someone to acquire us through a tender offer, proxy contest or otherwise.
 
     The Tennessee Business Combination Act provides that a party owning 10% or
more of the stock in a "resident domestic corporation" is an "interested
shareholder." An interested shareholder cannot engage in a business combination
with the resident domestic corporation unless the combination:
 
     - takes place at least five years after the interested shareholder first
       acquired 10% or more of the resident domestic corporation; and
 
   
     - either is approved by at least two-thirds of the non-interested voting
       shares of the resident domestic corporation or satisfies the fairness
       conditions specified in the Combination Act.
    
 
     These provisions apply unless one of two events occurs:
 
     - a business combination with an entity can proceed without delay when
       approved by the target corporation's board of directors before that
       entity becomes an interested shareholder, or
 
     - the resident corporation may enact a charter amendment or bylaw to remove
       itself entirely from the Combination Act. This charter or bylaw amendment
       must be approved by a majority of the shareholders who have held shares
       for more than one year before the vote. In addition, the charter
       amendment or bylaw cannot become operative until two years after the
       vote. An interested shareholder, for purposes of the Combination Act, is
       any person who is an affiliate or associate of the corporation, or the
       beneficial owner, directly or indirectly, of 10% or more of the
       outstanding voting shares of the corporation.
 
     The Tennessee Greenmail Act prohibits us from purchasing or agreeing to
purchase any of our securities, at a price higher than fair market value, from a
 
                                       63
<PAGE>   65
 
holder of 3% or more of any class of our securities who has beneficially owned
the securities for less than two years. We can make this purchase if the
majority of the outstanding shares of each class of voting stock issued by us
approves the purchase or we make an offer of at least equal value per share to
all holders of shares of that class.
 
     The effect of the above may make a change of control of our business harder
by delaying, deferring or preventing a tender offer or takeover attempt that you
might consider to be in your best interest. This includes those attempts that
might result in the payment of a premium over the market price for your shares.
They may also promote the continuity of our management by making it harder for
you to remove or change the incumbent members of the board of directors.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     Our charter provides that, to the fullest extent permitted by the Tennessee
Business Corporation Act, a director will not be liable to us or our
shareholders for monetary damages for breach of his or her fiduciary duty as a
director. Under the TBCA, directors have a fiduciary duty which is not
eliminated by this provision in our charter. In some circumstances, equitable
remedies such as injunctive or other forms of nonmonetary relief will remain
available. In addition, each director will continue to be subject to liability
under the TBCA for:
 
     - breach of the director's duty of loyalty;
 
     - acts or omissions which are found by a court of competent jurisdiction to
       be not in good faith or knowing violations of law;
 
     - actions leading to improper personal benefit to the director; and
 
     - payment of dividends that are prohibited by the TBCA.
 
This charter provision does not affect the directors' responsibilities under any
other laws, such as the Federal securities laws or state or Federal
environmental laws.
 
     The TBCA provides that a corporation may indemnify any director or officer
against liability incurred in connection with a proceeding if the director or
officer acted in good faith or reasonably believed, in the case of conduct in
his or her official capacity with the corporation, that the conduct was in the
corporation's best interest. In all other civil cases, a corporation may
indemnify a director or officer who reasonably believed that his or her conduct
was not opposed to the best interest of the corporation. In connection with any
criminal proceeding, a corporation may indemnify any director or officer who had
no reasonable cause to believe that his or her conduct was unlawful.
 
     In actions brought by or in the right of the corporation, however, the TBCA
does not allow indemnification if the director or officer is adjudged to be
liable to the corporation. Similarly, the TBCA prohibits indemnification of a
director or officer if the director or officer is adjudged liable in a
proceeding because a personal benefit was improperly received.
 
     In cases when the director or officer is wholly successful, on the merits
or otherwise, in the defense of any proceeding brought because of his or her
status as a director or officer of a corporation, the corporation must indemnify
the director or officer against reasonable expenses incurred in the proceeding.
Also, the TBCA provides that a court may order a corporation to indemnify a
director or officer for
 
                                       64
<PAGE>   66
 
reasonable expense if, in consideration of all relevant circumstances, the court
determines that the individual is fairly and reasonably entitled to
indemnification, whether or not the individual acted in good faith or reasonably
believed his or her conduct was in the corporation's best interest.
 
     Our bylaws provide that we shall indemnify and advance expenses to our
directors and officers to the fullest extent permitted by the TBCA. We also
intend to maintain insurance to protect any director or officer against any
liability and to enter into indemnification agreements to create a contractual
obligation to indemnify our directors and officers. These agreements, among
other things, indemnify our directors and officers for some expenses, including
attorneys' fees and associated legal expenses, judgments and fines and amounts
paid in settlement, actually and reasonably incurred by any of these persons in
any action, suit or proceeding arising out the person's services as our director
or officer. We believe that these provisions and agreements are necessary to
attract and retain qualified directors and officers.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of our common stock in the public market after
the offering could adversely affect the market price of our common stock and our
ability to raise equity capital in the future on terms favorable to us.
 
     After the offering, 10,948,600 shares of our common stock will be
outstanding, assuming that the underwriters do not exercise the over-allotment
option. Of these shares, all of the 2,500,000 shares sold in this offering will
be freely tradable without restriction or further registration under the
Securities Act, unless these shares are purchased by "affiliates" as that term
is defined in Rule 144 under the Securities Act. The remaining shares of common
stock held by existing shareholders are "restricted securities" as that term is
defined in Rule 144 under the Securities Act. Restricted securities may be sold
in the public market only if registered or if they qualify for an exemption from
registration under Rules 144 or 701 under the Securities Act, which rules are
summarized below.
 
     The following table shows approximately when the 8,448,600 shares of our
common stock that are not being sold in this offering but which will be
outstanding when this offering is complete will be eligible for sale in the
public market:

</TABLE>
    
 
     Resale of most of the restricted shares that will become available for sale
in the public market starting 180 days after the effective date will be limited
by volume and other resale restrictions under Rule 144 because the holders are
our affiliates.
 
RULE 144
 
     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year is entitled to sell, within any three-month
period, a number of shares that is not more than the greater of:
 
     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately 109,486 shares immediately after this offering; or
 
     - the average weekly trading volume of the common stock on the Nasdaq
       National Market during the four calendar weeks before a notice of the
       sale on Form 144 is filed.
 
     Sales under Rule 144 must also comply with manner of sale provisions and
notice requirements and to the availability of current public information about
us.
 
RULE 144(K)
 
     Under Rule 144(k), a person who has not been one of our affiliates at any
time during the 90 days before a sale, and who has beneficially owned the
restricted shares for at least two years, is entitled to sell the shares without
complying with the manner of sale, public information, volume limitation or
notice provisions of Rule 144.

<PAGE>   68
 
RULE 701
 
     In general, under Rule 701 of the Securities Act as currently in effect,
any of our employees, consultants or advisors who purchase shares from us under
a stock option plan or other written agreement can resell those shares 90 days
after the effective date of this offering in reliance on Rule 144, but without
complying with some of the restrictions, including the holding period, contained
in Rule 144. All of the options issued under our 1996 Stock Option Plan will
become immediately vested and exercisable upon consummation of this offering and
will be able to be resold after the 90 day period, subject to any lock-up
agreements.
 
LOCK-UP AGREEMENTS
 
     Executive officers, directors, shareholders and optionees who will hold an
aggregate of 10,518,340 shares of our common stock after this offering will sign
lock-up agreements under which they will agree not to transfer or dispose of,
directly or indirectly, any shares of common stock or any securities convertible
into or exercisable or exchangeable for shares of common stock, for a period of
180 days after the date of this prospectus. Transfers or dispositions can be
made sooner with the prior written consent of Hambrecht & Quist.
 
REGISTRATION RIGHTS
 
     Upon completion of this offering, the holders of 7,541,400 shares of our
common stock and of warrants to purchase 200,000 shares, 230,000 if the
underwriters' over-allotment option is exercised in full, of our common stock
will be entitled to rights with respect to the registration of their shares
under the Securities Act. Please see "Description of Capital
Stock -- Registration Rights" for a more detailed description of these
registration rights. After registration, these shares will become freely
tradeable without restriction under the Securities Act. Any sales of securities
by these shareholders could have a material adverse effect on the trading price
of our common stock.
 
STOCK OPTIONS
 
     Immediately after this offering we intend to file a registration statement
under the Securities Act covering 2,780,000 shares of common stock reserved for
issuance under our stock option plans. Each year as the number of shares
reserved for issuance under our 1999 Stock Incentive Plan increases, we will
file an amendment to the registration statement covering the additional shares.
As of March 31, 1999, options to purchase 1,852,740 shares of common stock were
issued and outstanding. All 1,852,740 options to purchase shares of common stock
will become vested at the date of this offering. When the lock-up agreements
described above expire, all of these options will be freely tradable. This
registration statement is expected to be filed and become effective as soon as
practicable after the effective date of this offering. Accordingly, shares
registered under that registration statement will, subject to vesting provisions
and Rule 144 volume limitations applicable to our affiliates, be available for
sale in the open market immediately after the 180 day lock-up agreements expire.

     The Underwriting Agreement provides that the obligations of the
underwriters are subject to conditions precedent, including the absence of any
material adverse change in our business and the receipt of certificates,
opinions and letters from us, our counsel and the independent auditors. The
nature of the underwriters' obligation is such that they are committed to
purchase all shares of common stock offered hereby if any shares are purchased.
 
     The following tables show the per share and total underwriting discounts
and commissions we will pay to the underwriters. These amounts are shown

     We estimate that the total expenses of this offering, excluding
underwriting discounts and commissions, will be approximately $800,000.
 
     The underwriters propose to offer the shares of common stock directly to
the public at the initial public offering price shown on the cover page of this
prospectus and to some dealers at such 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 some other dealers. After the
initial public offering of the shares, the offering price and other selling
terms may be changed by the underwriters. The representatives have informed us
that the underwriters do not intend to confirm discretionary sales of more than
5% of the shares of common stock offered in this offering.
 
     We have granted to the underwriters an option, exercisable no later than 30
days after the date of this prospectus, to purchase up to 375,000 additional
shares
 
                                       69
<PAGE>   71
 
of common stock at the initial public offering price, less the underwriting
discount stated on the cover page of this prospectus. To the extent that the
underwriters exercise this option, each of the underwriters will have a firm
commitment to purchase approximately the same percentage thereof which the
number of shares of common stock to be purchased by it shown in the above table
bears to the total number of shares of common stock offered hereby. We will be
obligated, pursuant to the option, 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 shares of common
stock offered hereby.
 
     The offering of the shares is made for delivery when, as and if accepted by
the underwriters and subject to prior sale and withdrawal, 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 they may
incur, including liabilities under the Securities Act, and to contribute to
payments the underwriters may be required to make in respect thereof.
 
     Our shareholders, including executive officers and directors, and optionees
who will own in the aggregate 10,518,340 shares of common stock after the
offering, have agreed not to, without the prior written consent of Hambrecht &
Quist LLC, 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 Hambrecht & Quist LLC, 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 hereof, and may grant additional options under our stock option plans,
provided that, without the prior written consent of Hambrecht & Quist LLC, the
additional options shall not be exercisable during that period.
 
     Prior to this offering, there has been no public market for the common
stock. The initial public offering price for the common stock will be determined
by negotiation among us and the representatives of the underwriters. Among the
factors to be considered in determining the initial public offering price are
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 our prospects, the present state of our business
operations, our management and other factors deemed relevant.
 
   
     Some of the persons participating in this offering may over-allot or effect
transactions which stabilize, maintain or otherwise affect the market price of
the common stock at levels above those which 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 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
    
 
                                       70
<PAGE>   72
 
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. This stabilizing, if commenced, may be
discontinued at any time.
 
                                 LEGAL MATTERS
 
   
     The validity of the common stock offered by this prospectus will be passed
upon for us by Bass, Berry & Sims PLC, Nashville, Tennessee. Legal matters in
connection with this offering will be passed upon for the underwriters by Wilson
Sonsini Goodrich & Rosati, Professional Corporation, Palo Alto, California.
    
 
                                    EXPERTS
 
     The audited financial statements and schedules included in this prospectus
and elsewhere in the registration statement have been audited by Arthur Andersen
LLP, independent public accountants, as indicated in their reports with respect
thereto, and are included herein in reliance upon the authority of said firm as
experts in giving said reports.
 
               CHANGE IN INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
     Our board of directors has selected Arthur Andersen LLP to serve as
independent auditors for the current fiscal year. Arthur Andersen LLP has served
as our independent auditors since November 11, 1998. On November 11, 1998, we
dismissed Kraft Bros, Esstman Patton & Harrell, PLLC as our independent
accountants. Kraft Bros' reports on the financial statements for the years ended
December 31, 1996 and 1997 did not contain any adverse opinion or disclaimer of
opinion and were not qualified or modified as to uncertainty, audit scope or
accounting principle. The decision to change independent accountants was
approved by the board of directors. During the years ended December 31, 1996 and
1997 and through November 11, 1998 there were no reportable events, as defined
in regulations of the Securities and Exchange Commission, or disagreements with
Kraft Bros on any matters of accounting principles or practices, financial
statement disclosure or auditing scope or procedure. Prior to retaining Arthur

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders of @plan.inc:
 
     We have audited the accompanying balance sheets of @plan.inc (a Tennessee
corporation) as of December 31, 1998 and 1997, and the related statements of
operations, shareholders' equity (deficit) and cash flows for the years then
ended and for the period from inception (May 29, 1996) to December 31, 1996.
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 in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of @plan.inc as of December 31,
1998 and 1997, and the results of its operations and its cash flows for the
years then ended and for the period from inception to December 31, 1996, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  GENERAL:
 
     @plan.inc was incorporated in the State of Tennessee in May 1996. We are
based in Stamford, Connecticut, and are a provider of Internet market research
systems for Internet advertisers, advertising agencies, Web publisher, online
retailers and consumer brand marketers.
 
2.  SIGNIFICANT ACCOUNTING POLICIES:
 
UNAUDITED INTERIM FINANCIAL INFORMATION
 
     The financial information as of March 31, 1999 and for the three months
ended March 31, 1998 and 1999 is unaudited, but includes all adjustments,
consisting only of normal recurring adjustments, that we consider necessary for
a fair presentation of our financial position at March 31, 1999, and our
operations and cash flows for the three months ended March 31, 1998 and 1999.
Operating results for the three months ended March 31, 1999 are not necessarily
indicative of results that may be expected for the entire year.
 
REVENUE RECOGNITION
 
     We provide Internet market research systems to our clients on a renewable
subscription basis. We recognize revenue ratably over the contract period, which
is generally twelve months. We bill our clients for our services based on terms
of the contracts, which may not coincide with criteria required for revenue
recognition.
 
     On the accompanying balance sheets, deferred revenue represents amounts
invoiced prior to rendering our services while unbilled receivables represents
the value of services rendered prior to being invoiced. Substantially all of the
deferred and unbilled revenue will be earned and billed, respectively, within
twelve months of the respective period ends.
 
     Upon signing a contract, our sales representatives become eligible for a
commission. These commissions are paid at the time of the contract signing. For
financial reporting purposes, we capitalize these commissions as a component of
prepaid expenses and amortize these amounts over the lives of the related
contracts.
 
CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents include cash on hand and all investments in
highly liquid instruments purchased with original maturities of three months or
less. Funds in excess of operating cash needs are maintained in a money market
fund, which may exceed the amount insured by the Federal Deposit Insurance
Corporation.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is stated at cost less accumulated depreciation and
amortization. Depreciation and amortization are calculated using the
straight-line method over the estimated useful lives of the assets, ranging from
three to five years.
 
SOFTWARE DEVELOPMENT COSTS
 
     We capitalize direct costs relating to our computer software development
upon the establishment of technological feasibility. Until our products reach
technological feasibility, all

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
costs related to development efforts are expensed as a component of product
costs. Software development costs, subsequent to technological feasibility and
prior to general release, have been capitalized and are reported at the lower of
unamortized cost or net realizable value. We amortize capitalized software
development costs on a straight-line basis for periods ranging from one to three
years. As of December 31, 1997 and 1998 and March 31, 1999, software development
costs are as follows:

</TABLE>
 
     We periodically review our software development costs and property and
equipment for any potential impairments. We consider undiscounted cash flows,
future operating results, trends or other relevant information in assessing
whether the carrying value of our assets is recoverable. At March 31, 1999, we
do not believe that any of our assets are impaired.
 
INCOME TAXES
 
     We recognize deferred tax assets and liabilities for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. Valuation allowances are
established when necessary to reduce deferred tax assets to the amount expected
to be realized.
 
LOSS PER SHARE
 
     Basic loss per share amounts are computed by dividing the net loss by the
weighted average number of shares of common stock outstanding during the period.
Diluted loss per share is computed by dividing the net loss by the weighted
average number of shares of common stock outstanding during the period plus the
effects of any potentially dilutive securities. In the accompanying statements
of operations, diluted loss per share does not include the effects of
potentially dilutive securities for all periods presented as they would have
been anti-dilutive in years in which a loss is reported.

     The following summarizes the securities outstanding which are excluded from
the loss per share calculation as amounts would have an antidilutive effect.
Preferred Stock is reflected on an "if-converted" basis. See note 4.

</TABLE>
 
STOCK-BASED COMPENSATION
 
     We account for our stock-based compensation to our employees by recognizing
compensation expense for the difference between the estimated fair value of our
stock at the date of grant and the exercise price of the granted stock.
Stock-based grants issued to non-employees are recorded at either the fair value
of the services provided at the fair value of the stock issued, as determined
using the Black-Scholes model.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires us to make estimates and assumptions.
These estimates and assumptions affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements. These assumptions also affect the reported amounts of
revenue and expenses during the reporting periods. Actual results could differ
from those estimates and assumptions.
 
CONCENTRATION OF CREDIT RISK
 
     We invest the majority of our cash balances in short-term, high quality
marketable securities. Our accounts receivable balances are domestic. No single
client represents a significant credit risk to us.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amount of all of our cash and cash equivalents, accounts
receivable and accounts payable approximate fair value due to the short-term
nature of these accounts.
 
STOCK-SPLIT
 
     The accompanying financial statements give retroactive effect to a 2,500
for 1 stock-split of our common stock which occurred on July 23, 1996 and a 1.8
for 1 stock-split that was approved by our Board of Directors on March 10, 1999.

4.  PREFERRED STOCK:
 
     Since our inception, we have issued three series of mandatory redeemable
convertible preferred stock. The following is a discussion of each of these
issuances.
 
     In 1996 and 1997, we issued a total of 448,000 shares of Series A preferred
stock and 2,016,000 shares of Series B preferred stock at a purchase price of
$1.00 and $2.00 per share, respectively. In 1998, we issued 1,725,667 shares of
Series C preferred stock at a purchase price of $3.00 per share. Each share of
preferred stock is convertible into 1.8 shares of common stock at any time, at
the option of the holder, or automatically upon successful completion of an
initial public offering yielding gross proceeds of at least $12.0 million and at
an initial public offering price of not less than $6.00 per share.
 
     We have reserved 7,541,400 shares of common stock for issuance upon
conversion of these convertible preferred shares.
 
     The preferred shareholders are not entitled to receive any preferential
dividends until the respective sixth anniversaries of the initial issuance dates
of the shares (Series A -- July 2002; Series B -- October 2002; Series
C -- January 2004). Thereafter, the preferred shareholders will be entitled to
receive dividends at the annual rate of $0.10, $0.20 and $0.30 per share,
respectively, on a cumulative basis from and after the sixth anniversary. Under
our Preferred Stock agreements, dividends on our common stock are restricted to
stock dividends through July 2002.
 
     We will redeem the preferred stock, if not previously converted, of each
preferred shareholder in 48 equal monthly installments beginning on the sixth
anniversary of the respective original issue dates. In the event of any
consolidation, merger, statutory share exchange, liquidation, dissolution or
winding up of our business, the holders of preferred stock will be paid first
out of any distribution of holders of our common and preferred stock at an
amount per share equal to $1.00, $2.00 and $3.00, respectively, plus any

to 8% of the number of shares sold in the offering at a price equal to the
initial price to the public. Of these warrants, 12.5% will be granted to the
director and officer. The preferred shareholders, including the director and
officer, will receive a pro rata portion of the remaining 75% of the warrants.
These warrants are exercisable for seven years.
 
     We will account for these warrants at the time of issuance as follows:
 
     - For warrants issued to the employee and director, we will apply the
       provisions of Accounting Principles Boards Opinion No. 25, "Accounting
       for Stock Issued to Employees," and record compensation expense for the
       difference between the fair value of our common stock at the time of
       grant, based on our initial public offering price, and the exercise price
       of the warrant. As these amounts are expected to be equivalent on the
       date of grant, we do not expect to record any compensation expense for
       these warrants.
 
     - For warrants issued to the holders of our preferred stock, we will record
       the value of these warrants, as determined by using the Black-Scholes
       model, as a dividend to these shareholders on the date of grant. This
       dividend will increase our accumulated deficit but will have no effect on
       reported net income (loss). While the actual value of the warrants issued
       to these shareholders cannot be determined until the date of grant, we
       estimate that the value of this dividend will approximate $1.2 million.
 
5.  STOCK OPTION PLAN:
 
     In 1996, we created the 1996 Stock Option Plan. This plan, as amended,
provides for stock option grants to employees, members of our board of
directors, our consultants and other persons having a business relationship with
us. Under this plan, the option price as determined by the board of directors
cannot be less than 100% of the fair market value of our common stock, at grant,
in the case of incentive stock options, and not less than 50% of the fair market
value of our common stock, at grant, in the case of non-qualified stock options.
Exceptions exist under certain conditions. No options will be exercisable more
than ten years after the date the option is granted. Options that we have
granted under our plan generally vest ratably over a four year period, beginning
at the date of grant. All unvested options will immediately vest upon an initial
public offering of our common stock.

     During 1999, we issued 47,340 options to our employees. These options had
an exercise price that was approximately $8.67 less per share than the fair
market value of our common stock on the date of grant. Accordingly, we plan to
recognize compensation expense of approximately $481,000 over the 48 month
vesting period for these options. During the three months ended March 31, 1999,
we recognized approximately $30,000 of this expense. However, as these options
will vest at the time of our initial public offering (see Note 8), we expect
that we will recognize the remaining $451,000 of expense during the second
quarter of 1999.

     In 1998, we granted 36,000 stock options at an exercise price of $3.33 to
non-employees. We recognized expense in the amount of $27,418 in connection with
these grants, which was estimated using the Black-Scholes model and the
following assumptions:
 
     - risk free interest rate of 5.3%,
 
     - expected dividend yield of 0%,
 
     - expected life of 5.0 years and
 
     - expected volatility of 0%
 
     The fair value of all of our other option grants is estimated on the date
of grant using the Black-Scholes model with the following weighted-average
assumptions used for grants in 1996, 1997 and 1998:
 
     - weighted-average risk free interest rates of 6.7%, 6.5% and 5.3%,
       respectively,
 
     - expected dividend yields of 0%,
 
     - expected lives of 6.0 years and
 
     - expected volatility of 0%.
 
     Except for the two series of option grants discussed above, no compensation
cost has been recognized for any option grants in the accompanying statements of
operations. Had compensation costs been recorded, our net loss and basic and
diluted loss per share would have been reduced from the following as reported
amounts to the following pro forma amounts:

     Since inception, we have generated losses for both book and tax purposes.
We have not recorded potential income tax benefits that we may receive from our
ability to apply current losses to future years in which we have taxable income.
Under accounting rules, these benefits can only be recorded when it is more
likely than not that these benefits will be realized. Due to our limited
operating history, we currently cannot make this assessment.
 
     At March 31, 1999, we have net operating loss carryforwards for federal and
state income tax purposes totaling approximately $5.1 million (unaudited), which
will expire from 2011 through 2014.
 
     Our net deferred tax asset consists of the following amounts of deferred

CONTRACTUAL COMMITMENTS
 
     We have a Letter of Agreement with The Gallup Organization, Inc. which was
entered into on September 6, 1996. This agreement was amended on January 5,
1998, August 20, 1998 and February 19, 1999. Under this agreement Gallup
provides us with initial baseline data and quarterly tracking survey research.
The agreement has a one-year term with nine successive one-year renewals, and is
cancelable only by us upon 90-days' written notice prior to an anniversary date.
 
8.  SUBSEQUENT EVENT (UNAUDITED):
 
     We are currently pursuing an initial public offering of our common stock.
We expect to offer approximately 2,500,000 shares of our common stock at an
initial offering price of approximately $13.00 per share.
 
     In March 1999, we adopted a new stock incentive plan (the 1999 Stock Plan).
The 1999 Stock Plan provides for the issuance of 800,000 options to purchase
common stock to key employees, consultants and non-employee directors. Options
to purchase 24,000 shares of common stock have been granted at the initial
public offering price in April 1999.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Under the Tennessee Business Corporation Act, there is no specific
provision either expressly permitting or prohibiting a corporation from limiting
the liability of its directors for monetary damages. Our charter provides that,
to the fullest extent permitted by the TBCA, a director will not be liable to
the corporation or its shareholders for monetary damages for breach of his or
her fiduciary duty as a director.
 
     The TBCA provides that a corporation may indemnify any director or officer
against liability incurred in connection with a proceeding if the director or
officer acted in good faith or reasonably believed, in the case of conduct in
his or her official capacity with the corporation, that the conduct was in the
corporation's best interest. In all other civil cases, a corporation may
indemnify a director or officer who reasonably believed that his or her conduct
was not opposed to the best interest of the corporation. In connection with any
criminal proceeding, a corporation may indemnify any director or officer who had
no reasonable cause to believe that his or her conduct was unlawful.
 
     In actions brought by or in the right of the corporation, however, the TBCA
does not allow indemnification if the director or officer is adjudged to be
liable to the corporation. Similarly, the TBCA prohibits indemnification in
connection with any proceeding charging improper personal benefit to a director
or officer if the director or officer is adjudged liable because a personal
benefit was improperly received.
 
                                      II-1
<PAGE>   92
 
     In cases when the director or officer is wholly successful, on the merits
or otherwise, in the defense of any proceeding instigated because of his or her
status as a director or officer of a corporation, the TBCA mandates that the
corporation indemnify the director or officer against reasonable expenses
incurred in the proceeding. Notwithstanding the foregoing, the TBCA provides
that a court may order a corporation to indemnify a director or officer for
reasonable expense if, in consideration of all relevant circumstances, the court
determines that the individual is fairly and reasonably entitled to
indemnification, whether or not the standard of conduct stated above was met.
 
     Our bylaws provide that we shall indemnify and advance expenses to our
directors and officers to the fullest extent permitted by the TBCA. We also
maintain insurance to protect any director or officer against any liability and
have entered into indemnification agreements with each of our directors.
 
     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under our charter. We are not aware of any threatened
litigation or proceeding that may result in a claim for such indemnification.

ITEM 17.  UNDERTAKINGS
 
     (a) The undersigned registrant hereby undertakes to provide to the
underwriter at the closing specified in the underwriting agreements certificates
in such denominations and registered in such names as required by the
underwriter to permit prompt delivery to each purchaser.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 14, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than payment by the registrant
of expenses incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.
 
     (c) The undersigned registrant hereby undertakes that: (i) for purposes of
determining any liability under the Securities Act of 1933, 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 filed by the
registrant 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; (ii) for the purpose of determining any liability under the
Securities Act of 1933, 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 such securities at that time
shall be deemed to be the initial bona fide offering thereof.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To @plan.inc:
 
     We have audited in accordance with generally accepted auditing standards,
the financial statements of @plan.inc included in this registration statement
and have issued our report thereon dated March 11, 1999. Our audit was made for
the purpose of forming an opinion on the basic financial statements taken as a
whole. The schedule of Valuation and Qualifying Accounts is the responsibility
of the Company's management and is presented for purposes of complying with the
Securities and Exchange Commissions rules and is not part of the basic financial
statements. This schedule has been subjected to the auditing procedures applied
in the audit of the basic financial statements and, in our opinion, fairly
states in all material respects the financial data required to be set forth
therein in relation to the basic financial statements taken as a whole.
