                               PROSPECTUS SUMMARY

   You should read the following summary together with the more detailed
information and Engage's financial statements and the notes to those statements
appearing elsewhere in this prospectus.

   This prospectus contains forward-looking statements based on our current
expectations, assumptions, estimates and projections about Engage and our
industry. These forward-looking statements involve risks and uncertainties.
Engage's actual results could differ materially from those anticipated in these
forward-looking statements as a result of various factors, as more fully
described in the "Risk Factors" section and elsewhere in this prospectus.

                           Engage Technologies, Inc.

                                  Our Business

   Engage provides products and services that enable customers to create and
use profiles of individual Web visitors to target advertisements, content and
e-commerce offerings. An Engage profile is an anonymous collection of
information about an individual Web user's consumer interests, demographic
characteristics and geographic location. These profiles are developed through a
combination of a user's browsing behavior on participating sites on the
Internet and information the user has voluntarily declared at those sites, such
as information provided on an online registration form. Each anonymous profile
omits information that would permit the personal identification of the user,
such as name, address and e-mail address.

   Based on its proprietary technology, Engage has built a database currently
containing more than 30 million anonymous consumer profiles, which it has
created using data drawn from multiple, diverse Web sites. When a user visits a
Web site of any customer subscribing to the Engage Knowledge data service,
Engage matches that visitor with his or her profile in the profile database.
The Web site can then use that profile to target offerings to the visitor based
on his or her particular preferences, demographic characteristics and
geographic location.

   Each Engage profile contains numerical scores that rank a Web user's
preference level in hundreds of standard categories and subcategories, such as
books, business, computers, fashion, sports and travel. Categories can be
further customized to meet the needs of a specific customer or market. These
profiles are continuously updated and refined based on a visitor's browsing
behavior across multiple Web sites, including pages selected by the user, the
duration of the user's visits and the responses of the user to specific
advertisements and promotions.

   Engage's products and services include:

  . Engage Knowledge, a service that is currently being tested with customers
    and will allow real-time access to Engage's centralized database of
    anonymous profiles of Web users;

  . Engage ProfileServer, a software product used by customers to create and
    deliver site-specific profiles of Web users;

  . Accipiter AdManager, an online advertising management system that
    automates the scheduling, targeting and delivery of ads on Web sites and
    the reporting of advertising campaign results;

  . Accipiter AdBureau, an outsourced online advertising management service
    using AdManager technology;

  . I/PRO services, which provide outsourced Web site traffic analysis and
    audits; and

  . Engage DecisionSupportServer, a software product that allows customers to
    perform sophisticated analyses of the behavior and interests of their Web
    site visitors.

        Our Operating History and Future Dependence on Engage Knowledge

   Although Engage expects that a significant portion of its future growth will
be attributable to sales of subscriptions to its Engage Knowledge data service
and other products and services that will be based upon Engage's profiling
technology, Engage has to date recognized no revenue from the Engage Knowledge
service. Engage expects to begin to recognize revenue from sales of
subscriptions to the Engage Knowledge service in late July 1999. Engage has
generated most of its revenue to date through sales of its advertising
management software and outsourced services, as well as its services for
measuring and analyzing Web site traffic. Engage has incurred aggregate net
losses of approximately $47.6 million since inception in 1995, including net
losses of approximately $13.8 million in fiscal 1998, and expects to continue
to incur significant losses for the foreseeable future. Engage's ability to
reduce these losses will depend in large part on our ability to generate
significant additional revenues. Engage operates in a highly competitive market
and it may not achieve profitability. Sales of products and services to
affiliates of CMGI have accounted for approximately 14% of Engage's total
revenue through April 30, 1999. In the first nine months of fiscal 1999,
approximately 87% of the Company's total revenue was attributable to sales of
products rather than services.

                             Our Market Opportunity

   The Internet is capable of transforming the way businesses market and sell
products. The interactive nature of the Web offers the potential for businesses
to market to individuals on a one-to-one basis in real-time. Businesses are
seeking to improve the effectiveness of their marketing campaigns by directing
their advertisements and promotions toward the Web users they most want to
reach. By targeting advertisements and promotions to the most relevant users,
Internet marketers seek to improve their response rates and brand awareness and
reduce costs by eliminating spending that is not directed to their desired
audience.

   While the growth and interactive nature of the Internet are generating a
large volume of consumer data useful for targeted marketing, Web users are
increasingly concerned about the potential for loss or abuse of their privacy.
To balance the desires of Internet marketers and consumers, there is a need for
a solution that enables marketers to tailor their offerings effectively to
individual users, while also preserving the privacy and anonymity available to
individuals on the Internet.

                                  Our Strategy

   Engage's strategy includes a number of elements designed to enhance its
position as a provider of profile-driven Internet marketing products and
services:

   Establish Engage as a recognized brand for Internet profiling. We believe we
   have the opportunity to establish Engage as the recognized brand for
   audience targeting on the Internet by developing a family of "Engage-
   enabled" products and services that use our proprietary profiling
   technology.

   Offer multiple products based on open standards. To promote broad acceptance
   of Engage profiles, we plan to continue to design our products based on open
   standards that enable our products to work both with our own applications
   and third-party applications.

   Continue to enhance profiles. We intend to continue to improve the quality
   and usefulness of Engage Knowledge profiles by increasing our installed base
   of subscribers to the Engage Knowledge data service, improving our profiling
   algorithms and technology and refining our profile categories to provide
   broader, more detailed and market-specific information.

   Focus on specific markets. We plan to tailor our profiling products for
   specific markets, including Web publishers and advertising networks as well
   as the automotive and retail markets.

   Offer family of Engage products and services. We intend to offer a range of
   different products and services to our existing installed base of customers.

                                       4
<PAGE>


   Maintain position as advocate for Internet privacy. We plan to maintain our
   commitment regarding issues of consumer privacy on the Internet.

              Risks that could affect our opportunity and strategy

   Our market opportunity could be diminished by customer concerns about Web
sites that collect data about their visitors and slower than expected growth in
Internet advertising. Our ability to achieve our business strategy could be
hindered by slower than anticipated customer acceptance of the Engage Knowledge
service or the inability of Engage profiles to improve the effectiveness of the
marketing campaigns of advertisers and merchants.

                                Control by CMGI

   CMGI will own approximately 82% of the outstanding common stock after this
offering. CMGI's ownership may have the effect of delaying or preventing a
change of control of Engage. In addition, CMGI will have the power to elect
Engage's entire board of directors and approve or disapprove mergers or other
significant corporate transactions submitted to Engage stockholders for
approval.

                                  RISK FACTORS

   This offering involves a high degree of risk. You should carefully consider
the risks described below before you decide to buy our common stock. If any of
the following risks were to occur, our business, financial condition or results
of operations would likely suffer. In that event, the trading price of our
common stock could decline, and you may lose all or part of your investment.

      We have incurred substantial losses and anticipate continued losses

   We have never been profitable. We have incurred net losses totalling $47.6
million from inception to April 30, 1999. We expect to increase our spending
significantly and therefore expect to continue to incur significant losses for
the foreseeable future.

   We will need to generate significant additional revenue to achieve
profitability. We may not achieve profitability. If our revenue grows more
slowly than we anticipate or if our operating expenses either increase more
than we expect or cannot be reduced in light of lower revenue, our business,
financial condition and results of operations will be materially and adversely
affected.

 We have recently begun to introduce our Engage Knowledge data service, and it
      is uncertain whether it will achieve widespread customer acceptance

   We have implemented our Engage Knowledge data service with customers on a
test basis and have not yet realized any revenue from sales of this service.
While we expect to implement this service on a commercial basis in July 1999,
we may encounter delays or difficulties in this commercial introduction. The
profiling capabilities used to create and maintain the Engage Knowledge data
service serve as the platform for most of our current and planned profile-based
products and services. We expect that a significant portion of our future
revenue will depend on sales of the Engage Knowledge data service and other
products and services incorporating our profile technology. There can be no
assurance that our Engage Knowledge data service, or our profiling approach for
the creation of anonymous profiles, will achieve widespread customer
acceptance, and any failure to do so would have a material adverse effect on
our business, financial condition and results of operations.

 Profile-based targeting may not achieve its intended benefits and our revenue
                       therefore may not grow as expected

   Our products and services are designed to enable Web publishers, advertisers
and merchants to target their intended audiences more effectively. Because
Engage profiling technology is new, we cannot be sure that the use of our
anonymous profiles will result in more effective targeting of advertisements or
other marketing and promotional activities. Our revenue would be adversely
affected if advertisers and merchants do not perceive that the use of profiles
will improve the effectiveness of their marketing campaigns or if our customers
are otherwise unable to generate a sufficient return on investment from the use
of our profiles. If the use of our profile-based products and services does not
demonstrably improve the responsiveness of Web visitors, Engage's business,
financial condition and results of operations will be materially adversely
affected.

The value of the Engage Knowledge service depends on continued contributions of
                data from customers subscribing to this service

   Decisions by our major customers not to contribute their data to the Engage
Knowledge database would hinder the quality and growth of the Engage Knowledge
database and could severely impair the effectiveness and value of the Engage
Knowledge data service and our other planned profile-based products. The
anonymous user profiles currently in the Engage Knowledge database have been
created from data generated by customers that are testing the Engage Knowledge
data service. Organizations subscribing to the Engage Knowledge data service
currently can elect not to contribute user data to the Engage profile database.
These organizations may elect not to contribute data due to concerns relating
to sharing proprietary information about their users and perceived privacy
concerns. Although

                                       8
<PAGE>

customers that do not contribute their data generally are required to pay
significantly higher subscription fees for use of the Engage Knowledge data
service, the impact of these higher fees may be insufficient to cause customers
to contribute data to the Engage Knowledge database.

Our business may be seriously harmed if we do not successfully develop profile-
                based products and services for specific markets

   We plan to develop Engage Knowledge data services that are tailored for the
requirements of specific markets, such as the automotive and retail markets.
Our success in introducing these services will depend on our ability to obtain
access to the consumer information necessary to create a meaningful database of
market-specific interests and preferences, as well as the ability to enter into
marketing relationships with partners having expertise in these markets. There
can be no assurance that we will be successful in obtaining this data or the
necessary marketing relationships, and any failure to do so would impair our
ability to introduce our planned products and services for these markets.

  Our quarterly operating results are subject to significant fluctuations and
       you should not rely on them as an indication of our future results

   Our revenue and operating results may vary significantly from quarter to
quarter due to a number of factors, not all of which are in our control. Future
revenue is difficult to forecast and for the foreseeable future will be
influenced by the timing and amount of sales to new customers, as well as user
traffic levels and advertising and electronic commerce activity on our
customers' Web sites.

   The market for profile-based marketing products and services is new. As a
result, we must educate potential customers on the use and benefits of our
products and services. In addition, the implementation of the Engage Knowledge
data service requires a significant commitment of resources by our customers.
It can, in some cases, take our sales organization several months to finalize a
sale. This makes it difficult to predict the quarter in which a sale may occur.

   Many of our expenses, particularly personnel costs and rent, are relatively
fixed, and are incurred in part based on expectations of future revenue. We may
be unable to adjust spending quickly enough to offset any unexpected revenue
shortfall. Accordingly, any shortfall in revenue may cause significant
variation in operating results in any quarter.

   Because of these factors, you should not rely on quarter-to-quarter
comparisons of our results of operations as an indication of our future
performance. It is possible that, in future periods, our results of operations
may be below the expectations of public market analysts and investors. This
could cause the trading price of our common stock to decline.

  We have only been in business for a short period of time and your basis for
                            evaluating us is limited

   We began commercial shipments of our first software products in early 1998.
You must consider the risks, expenses and uncertainties that an early stage
company like ours faces, particularly in the new and rapidly evolving Internet
market. Because we have only recently commenced commercial sales, our past
results and rates of growth may not be meaningful and you should not rely on
them as an indication of our future performance.

  We will continue to be controlled by CMGI, Inc., whose interests may differ
                            from other stockholders

   CMGI, Inc. currently beneficially owns approximately 96% of the outstanding
shares of our common stock, and after the offering will own approximately 82%
of the outstanding shares of our common stock. Accordingly, CMGI will continue
to have the power to elect our entire board of directors and to approve or
disapprove any corporate transaction or other matter submitted to our
stockholders for approval, including the approval of mergers or other
significant corporate transactions. The interests of CMGI may differ from the
interests of the other stockholders. Future decisions by CMGI as to the
disposition of any or all of its ownership position in Engage could be
influenced by the possible need of CMGI to maintain control of Engage in

                                       9
<PAGE>

order for CMGI to avoid becoming a registered investment company. Registration
as an investment company would subject CMGI to numerous regulatory requirements
with which CMGI would have difficulty complying. As a result, CMGI may be
motivated to maintain at least a majority ownership position of Engage, even if
other stockholders of Engage might consider a sale of control of Engage to be
in their best interests. As long as it is a majority stockholder, CMGI has
contractual rights to purchase shares in any financing of Engage sufficient to
maintain its majority ownership position. CMGI's ownership may have the effect
of delaying or preventing a change in control of us or discouraging a potential
acquiror from attempting to obtain control of us, which in turn could adversely
affect the market price of our common stock.

A material portion of our growth to date has been attributable to sales to CMGI
                                   affiliates

   Eleven of our customers are affiliates of CMGI. In fiscal 1998, sales of
products and services to affiliates of CMGI accounted for $235,000, or
approximately 11%, of Engage's total revenue. In the first nine months of
fiscal 1999, sales of products and services to affiliates of CMGI accounted for
$1.4 million, or approximately 15%, of Engage's total revenue. To the extent
that our growth in revenue has been attributable to sales of products and
services to these affiliates, there can be no assurance that our historical
rate of growth is an indication of our future prospects.

             The terms of our sales to CMGI affiliates could change

   While Engage believes that the transactions between it and other affiliates
of CMGI have been on arms'-length terms, it is possible that Engage might have
received more favorable terms than it would have if it were not an affiliate of
CMGI. In addition, the terms of our sales to affiliated customers could change
if these customers cease to be affiliates of CMGI in the future. CMGI has been
and continues to be instrumental in introducing Engage to customers and other
business partners. If the relationship between Engage and CMGI ended or was
fundamentally altered, our business, financial condition and results of
operations could be materially adversely affected.

 Growing concerns about the use of "cookies" and data collection may limit our
                        ability to develop user profiles

   Web sites typically place small files of information commonly known as
"cookies" on a user's hard drive, generally without the user's knowledge or
consent. Cookie information is passed to the Web site through the Internet
user's browser software. Our technology currently uses cookies to collect
information about an Internet user's movement through the Internet. Most
currently available Internet browsers allow users to modify their browser
settings to prevent cookies from being stored on their hard drive, and a small
minority of users are currently choosing to do so. Users can also delete
cookies from their hard drive at any time.

   Some Internet commentators and privacy advocates have suggested limiting or
eliminating the use of cookies. The effectiveness of our technology could be
limited by any reduction or limitation in the use of cookies.

   If the use or effectiveness of cookies is limited, we would likely have to
switch to other technology that allows us to gather demographic and behavioral
information. While such technology currently exists, it is substantially less
effective than cookies. Replacement of cookies could require significant
reengineering time and resources, might not be completed in time to avoid
negative consequences to our business, financial condition or results of
operations, and might not be commercially feasible.

   In addition, privacy concerns may cause some Web users to be less likely to
visit Web sites that subscribe to the Engage Knowledge data service. If enough
Web users choose not to visit sites using or providing information to the
Engage Knowledge data service, our ability to sell subscriptions to the Engage
Knowledge data service would be adversely affected.This would, in turn, have a
material adverse effect on our business, financial condition or results of
operations.

                                       10

   Legislation or regulations may be adopted that could affect our ability to
 generate or use information for profiles and may hinder our ability to conduct
                                    business

   The legal and regulatory environment governing the Internet and the use of
information about Web users is uncertain and may change. United States
legislators in the past have introduced a number of bills aimed at regulating
the collection and use of personal data from Internet users and additional
similar bills are being considered during the current congressional session.
Although we believe that none of the current bills, as drafted, would have a
material adverse effect on our business, it is possible that a bill may be
modified and enacted into law that negatively affects our ability to collect
and use data about Web users. The European Union has recently adopted a
directive addressing data privacy that may result in limitations on the
collection and use of specific personal information regarding Internet users.
In addition, Germany has imposed its own laws protecting data that can become
personally identifiable through subsequent processing. Other countries may also
enact limitations on the use of personal data.

   To date, these regulations have not materially restricted the use of our
products. However, legislation or regulations may in the future be adopted
which may limit our ability to target advertising or collect and use
information in one or more countries. Further, a number of laws and regulations
have been and may be adopted covering issues such as pricing, acceptable
content, taxation and quality of products and services on the Internet. Such
legislation could dampen the growth in use of the Internet generally and
decrease the acceptance of the Internet as a communications and commercial
medium. In addition, due to the global nature of the Internet, it is possible
that multiple federal, state or foreign jurisdictions might inconsistently
regulate our activities and our customers. Any of the foregoing developments
could have a material adverse effect on our business, financial condition and
results of operations.

            We may have difficulty managing our expanding operations

   We have recently experienced a period of rapid growth. This growth has
placed a significant strain on our managerial, operational and financial
resources. Our total revenue increased from $25,000 in the fiscal year ended
July 31, 1997 to $2.2 million in the fiscal year ended July 31, 1998, and the
number of our employees increased from 67 as of July 31, 1997 to 209 as of
April 30, 1999. A number of our senior managers have been with us for less than
a year. To accommodate this growth, we must implement new or upgraded operating
and financial systems, procedures and controls throughout many different
locations. We may not succeed in these efforts. Our failure to expand and
integrate these areas in an efficient manner could have a material adverse
effect on our business, financial condition and results of operations. If we
continue to grow, we will need to recruit, train and retain a significant
number of employees, particularly employees with technical, marketing and sales
backgrounds. These individuals are in high demand. We may not be able to
attract the staff we need.

   The acceptance and effectiveness of Internet advertising is not yet fully
                                  established

   Our future success is dependent in part on an increase in the use of the
Internet as an advertising medium. The Internet advertising market is new and
rapidly evolving, and it cannot yet be compared with traditional advertising
media to gauge its effectiveness. As a result, demand for and market acceptance
of Internet advertising solutions are uncertain. In addition, there are
software programs that limit or prevent advertising from being delivered to a
user's computer. Web users' widespread adoption of such software would
significantly undermine the commercial viability of Internet advertising. If
the market for Internet advertising fails to develop or develops more slowly
than we expect, our business, financial condition and results of operations
could be materially and adversely affected.

                                       11
<PAGE>

   There are currently no generally accepted standards for the measurement of
the effectiveness of Internet advertising and standard measurements may need to
be developed to support and promote Internet advertising as a significant
advertising medium. Our advertising customers may challenge or refuse to accept
our or third-party measurements of advertisement delivery requests from the Web
sites of Web publishers using our solutions.

   The acceptance and effectiveness of the Internet as a medium for consumer
                   transactions is not yet fully established

   Our future success is dependent in part on an increase in the use of the
Internet for business transactions with consumers. The electronic commerce
market is new and rapidly evolving and the extent of consumer acceptance of the
Internet is uncertain. If a sufficiently broad base of consumers do not accept
the use of the Internet for transacting business, our business, financial
condition and results of operations could be materially and adversely affected.

      We have many competitors and may not be able to compete effectively

   The markets for Internet advertising, user targeting and Web site assessment
tools are intensely competitive. We compete directly with providers of
profiling technology, such as Personify, and indirectly with applications that
include more limited profiling capability integrated into their solutions, such
as BroadVision and Vignette. In addition, NetGravity, in concert with Aptex and
MatchLogic, and businesses that offer cash or other incentives to users to
voluntarily provide profile data, are expected to compete in the profiling
solutions market. The primary competitors to our advertising management
software are systems provided by NetGravity and Real Media. In the outsourced
ad serving market, we compete with providers of ad serving services, including
AdForce and DoubleClick. Our traffic measurement and analysis services and
software compete with software offered by Accrue, Andromedia, net.Genesis and
WebTrends, and our audit services compete with ABC Interactive, BPA and
PricewaterhouseCoopers. We also encounter competition from a number of other
sources, including content aggregation companies, companies operating
advertising sales networks, advertising agencies and other companies that
facilitate Internet advertising and electronic commerce.

   Many of our existing competitors, as well as a number of potential new
competitors, have longer operating histories, greater name recognition, larger
customer bases and significantly greater financial, technical and marketing
resources than we do. Such 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 competitors will not develop products
or services that are equal or superior to our solutions or that achieve greater
market acceptance than our solutions. In addition, current and potential
competitors have established or may establish cooperative relationships among
themselves or with third parties. Increased competition is likely to result in
price reductions, reduced gross margins and loss of market share. We cannot
assure you that we will be able to compete successfully or that competitive
pressures will not materially and adversely affect our business, financial
condition and results of operations.

   Companies doing business on the Internet, including ours, must also compete
with television, radio, cable and print media for a share of advertisers' total
advertising budgets.

Our systems may fail or experience slowdowns and we could lose key data used in
                               our user profiles

   Substantially all of our communications hardware and other data center
operations are located at NaviSite Inc.'s facilities in Andover, Massachusetts.
Fire, floods, earthquakes, power loss, telecommunications failures, break-ins
and similar events could damage these systems, including loss of data used to
create our user profiles. Our business, financial

                                       12
<PAGE>

condition and results of operations could be materially and adversely affected
if our systems were affected by any of these occurrences or if any data used in
our Engage Knowledge database were lost. Our insurance policies may not
adequately compensate us for any losses that may occur due to any failures or
interruptions in our systems or loss of data.

      We may need additional financing which could be difficult to obtain

   We intend to grow our business rapidly and expect to incur significant
operating losses for the foreseeable future. Therefore, we may require
significant external financing in the future. Obtaining additional financing
will be subject to a number of factors, including:

  . market conditions;

  . our operating performance; and

  . investor sentiment, particularly for Internet-related companies.

   These factors may make the timing, amount, terms and conditions of
additional financing unattractive for us. If we are unable to raise capital to
fund our growth, our business, financial condition and results of operations
would be materially and adversely affected.

       Technological change may render our products and services obsolete

   The Internet market is characterized by rapidly changing technology,
evolving industry standards, frequent new product announcements and
enhancements and changing customer demands. The introduction of new products
and services embodying new technologies and the emergence of new industry
standards can render existing products and services obsolete. Our success
depends on our ability to adapt to rapidly changing technologies and to improve
the performance, features and reliability of our services and products in
response to changing customer and industry demands. Furthermore, we may
experience difficulties that could delay or prevent the successful design,
development, testing, introduction or marketing of services. New services or
enhancements to existing services may not adequately meet the requirements of
our current and prospective customers or achieve any degree of significant
market acceptance.

           We face risks associated with our international operations
                            and plans for expansion

   We have operations in a number of international markets. We intend to
continue to expand our international operations and international sales and
marketing efforts. To date, we have limited experience in developing localized
versions of our solutions and in marketing, selling and distributing our
solutions internationally. We have established a direct sales office in the
United Kingdom and a joint venture with Sumitomo to conduct operations in
Japan. We intend to enter other international markets primarily by partnering
with locally based third parties, including entering into joint ventures and
distribution arrangements. Our success in such markets is directly dependent on
the success of our business partners and our and their dedication of sufficient
resources to our relationship.

   International operations are subject to other inherent risks, including:

  . compliance with the laws and regulations of different countries;

  . difficulties in enforcing contractual obligations and intellectual
    property rights in some countries;

  . difficulties and costs of staffing and managing foreign operations; and

  . fluctuations in currency exchange rates.

   These risks may materially and adversely affect our business, results of
operations and financial condition.

   We may not be successful in acquiring and integrating new technologies or
                                   businesses

   We have acquired two companies and intend in the future to continue to
acquire or make investments in complementary businesses, products, services or
technologies. We cannot assure you that we will be able to identify additional
acquisition or investment candidates. Even if we do identify suitable

                                       13
<PAGE>

candidates, we cannot assure you that we will be able to make such acquisitions
or investments on commercially acceptable terms. We recently purchased I/PRO
and may not be successful in managing its operations. In addition, the key
personnel of I/PRO or other acquired companies 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 adversely affect our
results of operations. 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 stockholders.

      We depend on the continued viability of the Internet infrastructure

   Our success depends upon the development and maintenance of a viable
Internet infrastructure. The current Internet infrastructure may be unable to
support an increased number of users. The timely development of products such
as high-speed modems and communications equipment will be necessary to continue
reliable Web access. Furthermore, the Web has experienced outages and delays as
a result of damage to portions of its infrastructure. Such outages and delays,
including those resulting from Year 2000 problems, could adversely affect Web
sites and the level of traffic on our customers' sites. The effectiveness of
the Web may decline due to delays in the development or adoption of new
standards and protocols designed to support increased levels of activity. If
such new infrastructure, standards or protocols are developed, we may be
required to incur substantial expenditures to adapt our products to the new
technologies.

     Our business may suffer if we cannot protect our intellectual property

   Our success and ability to compete are substantially dependent on our
internally developed technologies and trademarks, which we seek to protect
through a combination of patent, copyright, trade secret and trademark law. In
February 1998, we filed two patent applications in the United States. We cannot
assure you that any of our patent applications or trademark registrations will
be approved, or even if approved, would not be successfully challenged by
others or invalidated. In addition, we cannot assure you that we will be able
to prevent misappropriation of our solutions or technologies, particularly in
foreign countries where laws or law enforcement practices may not protect our
proprietary rights as fully as in the United States.

   Our profiling technology collects and utilizes data derived from user
activity on our customers' Web sites. This data is used for advertising and
content targeting. Although we believe that we have the right to use such data
and the compilation of such data in our database, we cannot assure you that any
trade secret, copyright or other protection will be available for such
information. In addition, others may claim rights to such information.

       Our business will suffer if we are unable to retain key personnel

   We depend on the services of our senior management and key technical
personnel. In particular, our success depends on the continued efforts of our
Chief Executive Officer, Paul L. Schaut; our Chief Operating Officer, David A.
Fish; and our Chief Technology Officer, Daniel J. Jaye, with whom we do not
have employment agreements. The loss of the services of any key employee could
have a material adverse effect on our business, financial condition and results
of operations.

                  Year 2000 problems may disrupt our business

   Many currently installed computer systems and software products only accept
two digits to identify the year in any date. Therefore, the year 2000 will
appear as "00", which the system might consider to be the year 1900 rather than
the year 2000. This could result in system failures, delays or miscalculations
causing disruptions to our operations.

                                       14
<PAGE>

   The failure of any of our systems or systems maintained by third parties to
be Year 2000 compliant could:

  . cause us to incur significant expenses to remedy any problems;

  . affect the availability and performance of our network; or

  . otherwise seriously damage our business.

   A significant Year 2000-related disruption to our network could cause our
users, advertisers or electronic commerce partners to be dissatisfied with our
network or could impose an unmanageable burden on our technical support staff.
Our failure to correct a material Year 2000 problem could have a material
adverse effect on our business, financial condition and results of operations.

 Engage will continue to rely on CMGI for various administrative services, and
      conflicts of interest could arise in the provision of such services

   Upon the closing of this offering, CMGI and Engage will enter into a
facilities and administrative support agreement under which CMGI will continue
to make available space at its headquarters in Massachusetts and will provide
various services to Engage, including tax and administration, computer and
information systems, telecommunications, utilities and employee benefits
administration. Under this agreement, CMGI has agreed to make available to
Engage at least 28,000 square feet of space at its headquarters facilities in
Andover, Massachusetts, subject to termination upon at least 12 months' notice
by CMGI. The fees payable by Engage for the availability of space and other
services are typically determined through an allocation of CMGI's costs based
upon the proportion of Engage's employee headcount to the total headcount of
CMGI and other CMGI-related companies located in the same facility or using the
same services. We have not independently determined the market value for these
services and may be paying more than fair market value for them if this
allocation method does not fairly reflect Engage's use of these services or if
CMGI were obtaining them at rates greater than their fair market value. This
agreement may be amended by agreement of CMGI and Engage. It is possible that
personnel of CMGI providing these services may encounter conflicts of interests
such as demands on their time by CMGI that might detract from their level of
availability or service to Engage. In addition, Engage's reliance on these
services could result in higher costs than would be incurred if Engage were to
obtain such services from an unrelated third party.

     We will have discretion as to the use of the proceeds of this offering

   We currently have no specific uses planned for the net proceeds of this
offering. As a result, our management will have broad discretion in applying
the net proceeds of this offering, and could include uses with which
stockholders may disagree. The failure of management to apply such funds
effectively could have a material adverse effect on our business, financial
condition and results of operations. See "Use of Proceeds".

Our stock price is likely to be highly volatile

   Following this offering, an active trading market may not develop or be
sustained for our common stock. The price at which our common stock will trade
after this offering is likely to be highly volatile and may fluctuate
substantially due to a number of factors, including:

  . actual or anticipated fluctuations in our results of operations;

  . changes in or our failure to meet securities analysts' expectations;

  . technological innovations;

  . increased competition;

  . conditions and trends in the Internet and other technology industries;
    and

  . general market conditions.

   In addition, the stock market has from time to time experienced significant
price and volume fluctuations that have affected the market prices for the
securities of technology companies, particularly Internet companies. These
broad market fluctuations may result in a

                                       15
<PAGE>

material decline in the market price of our common stock, regardless of our
operating performance. In the past, following periods of volatility in the
market price of a particular company's securities, securities class action
litigation has often been brought against that company. We may become involved
in this type of litigation in the future. Litigation is often expensive and
diverts management's attention and resources, which could have a material
adverse effect upon our business, financial condition and results of
operations.

   Shares eligible for public sale after this offering could adversely affect
                                our stock price

   The availability of a large number of shares for sale could result in the
need for sellers to accept a lower price in order to complete a sale. This
would result in a lower market price of our common stock. After this offering,
there will be outstanding 46,911,798 shares of our common stock, or 47,811,798
shares if the underwriters' over-allotment option is exercised in full. Of
these shares, the 6,000,000 shares sold in this offering will be freely
tradeable except for any shares purchased by our "affiliates" as defined in
Rule 144 under the Securities Act. Of the remaining 40,911,798 shares of common
stock held by existing stockholders, 40,219,464 are subject to 180-day lock-up
agreements and are eligible for sale only if registered or if they qualify for
an exemption from registration under Rules 144, 144(k) or 701 under the
Securities Act. Subject to the provisions of Rules 144, 144(k) and 701, at
least 30,477,194 shares will be available for sale in the public market 180
days after the date of this prospectus, subject in the case of shares held by
affiliates to compliance with applicable volume restrictions.

               You will suffer immediate and substantial dilution

   The initial public offering price per share will significantly exceed the
net tangible book value per share. If Engage were to liquidate immediately
after the offering, investors purchasing shares in this offering would receive
a per share amount of tangible assets net of liabilities that would be less
than the initial public offering price per share. Investors purchasing shares
in this offering will suffer dilution of $12.99 per share from their
investment.

 Some shares in this offering may
   have been offered or sold in
  violation of the Securities Act
              of 1933

   Prior to the effectiveness of the registration statement covering the shares
of our common stock being sold in this offering, Hambrecht & Quist, an
underwriter of this offering, provided written materials to approximately 80
employees of Engage that we had designated as potential purchasers of up to
300,000 shares of common stock in this offering through a directed share
program. These materials may constitute a prospectus that does not meet the
requirements of the Securities Act of 1933. No employee who received these
written materials should rely upon them in any manner in making a decision
whether to purchase shares of common stock in this offering.

   If the distribution of these materials by Hambrecht & Quist did constitute a
violation of the Securities Act of 1933, the recipients of these materials who
purchased common stock in this offering would have the right, for a period of
one year from the date of their purchase of common stock, to obtain recovery of
the consideration paid in connection with their purchase of common stock or, if
they had already sold the stock, sue us for damages resulting from their
purchase of common stock. These damages could total up to approximately $4.5
million plus interest, based on the initial public offering price of $15.00 per
share, if these investors seek recovery or damages after an entire loss of

                                USE OF PROCEEDS

   Engage estimates that the net proceeds from its sale of 6,000,000 shares of
common stock will be $82.4 million, after deducting the underwriting discount
and estimated offering expenses payable by Engage. If the underwriters' over-
allotment option is exercised in full, Engage estimates that the net proceeds
will be $95.0 million.

   Engage presently intends to use a portion of the net proceeds from this
offering for general corporate purposes, including working capital, product
development, increasing sales and marketing capabilities and expanding
international operations. Engage may also use a portion of the net proceeds to
acquire or invest in complementary businesses or products or to obtain the
right to use complementary technologies. Engage has no specific understandings,
commitments or agreements with respect to any such acquisition or investment.
Pending these uses, the net proceeds of this offering will be invested in
short-term, interest-bearing, investment-grade securities.

                                DIVIDEND POLICY

   Engage has never declared or paid any cash dividends on its capital stock.
Engage presently intends to retain future earnings, if any, to finance the
expansion of its business and does not expect to pay any cash dividends in the
foreseeable future. Payment of future cash dividends, if any, will be at the
discretion of Engage's board of directors after taking into account various
factors, including Engage's financial condition, operating results, current and
anticipated cash needs and plans for expansion.

                                CAPITALIZATION


   The following table sets forth Engage's capitalization as of April 30,
1999:

  . on an actual basis after giving effect to the two-for-one common stock
    split;

  . on a pro forma basis to reflect the conversion of Engage's debt to CMGI
    into convertible preferred stock and the conversion of all of Engage's
    convertible preferred stock into common stock and the sale of 938,000
    shares of common stock to be issued prior to the closing of this offering
    for net proceeds of approximately $13.1 million; and

  . on a pro forma as adjusted basis to reflect the conversion of Engage's
    debt to CMGI into convertible preferred stock, the conversion of all of
    Engage's convertible preferred stock into common stock and the sale of
    938,000 shares of common stock to be issued prior to the closing of this
    offering for net proceeds of approximately $13.1 million and the
    application of the estimated net proceeds from the sale of common stock
    in this offering, after deducting the underwriting discount and estimated
    offering expenses payable by Engage.

   Historically, CMGI has funded Engage's operations as needed, with a
corresponding increase in Engage's debt to CMGI. Customer and other receipts
are transferred to CMGI and are applied to reduce Engage's obligations to
CMGI. Engage expects that it will continue to borrow funds from CMGI under
this arrangement until the closing of this offering and that the net
obligations incurred after the end of the fiscal quarter preceding the
closing, to the extent outstanding, will be converted into additional shares
of Engage common stock at the initial public offering price.

                                    DILUTION

   The pro forma net tangible book value of Engage as of April 30, 1999 was
approximately $11.7 million, or approximately $.29 per share of common stock.
Pro forma net tangible book value per share represents the amount of Engage's
total tangible assets less total liabilities, divided by the pro forma number
of shares of common stock outstanding, after giving effect to the conversion of
Engage's debt to CMGI into convertible preferred stock and the conversion of
all of Engage's convertible preferrred stock into common stock, the sale of
938,000 shares of common stock to be issued prior to the closing of this
offering for net proceeds of approximately $13.1 million and the two-for-one
stock split. After giving effect to the sale of the common stock offered by
Engage in this offering and after deducting the underwriting discount and
estimated offering expenses payable by Engage, the pro forma net tangible book
value of Engage, as adjusted, as of April 30, 1999 would have been
approximately $94.1 million or approximately $2.01 per pro forma share of
common stock. This represents an immediate increase in net tangible book value
of $1.72 per share to Engage's existing stockholders and an immediate dilution
in net tangible book value of $12.99 per share to new investors of common stock
in this offering. If the initial public offering price is higher or lower, the
dilution to the new investors will be greater or less, respectively. The
following table illustrates this per share dilution:

   This discussion and table assume no exercise of options outstanding under
Engage's 1995 Equity Incentive Plan. As of April 30, 1999, there were options
outstanding to purchase a total of 6,467,794 shares of common stock at a
weighted average exercise price of $2.16 per share. To the extent that any of
these options are exercised, there will be further dilution to new investors.

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

   The following discussion should be read in conjunction with Engage's
financial statements and notes to those statements and other financial
information appearing elsewhere in this prospectus. In addition to historical
information, the following discussion and other parts of this prospectus
contain forward-looking information that involves risks and uncertainties.
Engage's actual results could differ materially from those anticipated by such
forward-looking information due to various factors, including, but not limited
to, those set forth under "Risk Factors" and elsewhere in this prospectus.

   References to fiscal 1996, fiscal 1997 and fiscal 1998 mean the fiscal years
ended July 31, 1996, 1997 and 1998, respectively.

                                    Overview

   Engage offers a range of software products and services that enable Web
publishers, advertisers and merchants to target and deliver advertisements,
content and e-commerce offerings to their audiences and to measure their
effectiveness.

   Engage commenced operations in September 1995 as a wholly-owned subsidiary
of CMGI. As of April 30, 1999, CMGI owned approximately 96% of the outstanding
common stock of Engage.

   Engage derives its revenues from product revenue and service and support
revenue. Product revenue consists of revenue from: (1) licenses of its software
products, AdManager, ProfileServer and DecisionSupportServer, and (2)
subscriptions to its service offerings, AdBureau advertising management
services, I/PRO web site traffic measurement, auditing and analysis services
and the Engage Knowledge data service.

   Product licenses are typically perpetual, although some have a one to three
year term. The fees for licenses of AdManager vary based on the volume of
advertisements served, and the fees for licenses of ProfileServer and
DecisionSupportServer vary based on the volume of activity on the customer's
site. Engage recognizes revenue from product licenses when a signed, non-
cancellable license exists, delivery of the product has occurred and Engage's
fees are fixed and determinable and collection is probable. Engage typically
recognizes revenue from perpetual product licenses in the quarter in which the
software is shipped and recognizes revenue from periodic licenses ratably over
the period of the license.

   Subscriptions to Engage's services typically have a one year term, although
some are on a quarterly basis. The subscription fees for the Engage Knowledge
data service vary based on traffic to the customer's site, contributions of
data by the customer and the application with which the service is used. In the
future, fees may also vary based on the number of profiles used. The fees for
AdBureau vary based on the number of advertisements served. Revenue is
recognized ratably over the period of the subscription or, in the case of
usage-based subscriptions, monthly based on actual usage. Subscription
agreements typically include terms for automatic renewal unless the customer

   Engage's support and service revenue derives from its software maintenance
and other professional services, including consulting, installation and
training. Engage recognizes revenue from these services upon the delivery of
these services or, in the case of maintenance agreements, over the term of the
agreement. To date, substantially all of Engage's customers have entered into
maintenance contracts.

   Engage began commercial shipments of its first software products,
ProfileServer and DecisionSupportServer, in the early part of fiscal 1998.
Effective April 1998, Engage acquired Accipiter, Inc., and began to sell the
Accipiter AdManager system and subscriptions to the Accipiter AdBureau service.
In April 1999, Engage acquired Internet Profiles Corporation (I/PRO) and began
to sell the I/PRO line of analysis and audit products and services. As of April
30, 1999, Engage had implemented its Engage Knowledge data service with
customers on a test basis.

                                       21

   Engage has not recognized any revenue from the Engage Knowledge data service
through April 30, 1999. However, Engage expects that a significant portion of
its future revenue will be attributable to the Engage Knowledge data service
and other products and services based on its profiling technology that enable
its customers to create and use profiles that categorize information about a
Web user's consumer and demographic characteristics and geographic location.
Engage expects that it will begin to implement this service on a commercial
basis in July 1999. Any failure of the Engage Knowledge data service, or
Engage's global profiling technology, to achieve widespread customer acceptance
would have a material adverse effect on Engage's business, financial condition
and results of operation.

   Engage's revenue from sales to related parties consists of sales of products
and services to customers that are affiliates of CMGI. In the nine months ended
April 30, 1999, Engage sold products and services to 11 affiliates of CMGI.
Engage believes that the terms and conditions of those sales are not materially
different than the terms and conditions of sales to unrelated third parties.

   In August 1997, Engage sold rights to some of its data warehouse products to
Red Brick Systems, Inc. for $9.5 million in cash and 238,160 shares of Red
Brick common stock, recording a pretax gain of $9.2 million on the sale. In
January 1999, the Red Brick shares were exchanged for 142,896 shares of
Informix Corp. due to Informix's acquisition of Red Brick.

   In April 1998, CMGI acquired Accipiter, which sells Internet advertising
management solutions, in exchange for 10,109,536 shares of CMGI common stock.
In August 1998, Accipiter was merged with Engage in a stock-for-stock merger in
which 700,000 shares of Engage's Series A convertible preferred stock were
issued to CMGI. Engage has reflected the acquisition of Accipiter in its
consolidated financial statements as if it occurred in April 1998. The total
purchase price for Accipiter was valued at $31.3 million. Upon consummation of
the Accipiter acquisition, CMGI, in its consolidated financial statements,
reported an expense of approximately $18.0 million representing acquired in-
process research and development that had not yet reached technological
feasibility and had no alternative future use. On May 7, 1999, CMGI announced a
voluntary restatement of the in-process research and development charge related
to the Accipiter acquisition to address valuation methodologies suggested by
the Securities and Exchange Commission in a letter dated September 9, 1998 to
the American Institute of Certified Public Accountants SEC Regulations
Committee and as clarified through subsequent practice. Upon consideration of
this guidance and additional practice that has developed since the Commission's
letter was first made public, the $18.0 million charge as previously reported
by CMGI has been reduced to $9.2 million and amounts allocated to goodwill and
other intangible assets have been increased from $11.5 million to $20.3
million. Engage has reflected the Accipiter acquisition accounting in its
consolidated financial statements as adjusted for the current Commission
methodologies.

   Approximately $1.7 million of deferred compensation was recorded during
fiscal 1998 relating to approximately 173,080 shares of CMGI common stock held
in escrow to be issued to employee stockholders of Accipiter who satisfy a two-
year employment continuation provision. Compensation expense is being
recognized over the two-year service period beginning April 1, 1998. The
acquisition has been accounted for using the purchase method, and, accordingly,
the purchase price has been allocated to the assets purchased and liabilities
assumed based upon their fair values at the date of acquisition. The portion of
the purchase price allocated to goodwill and developed technology is being
amortized on a straight-line basis over five years. Amounts allocated to the
employee workforce and the Accipiter trade name are being amortized on a
straight-line basis over two years.

   In August 1998, Engage acquired, for $1.4 million in cash, 49% of the shares
of Engage Technologies Japan, a joint venture with Sumitomo Corporation in
Japan. Engage's ownership interest was subsequently reduced to 46% after the
issuance of additional equity in the joint venture to a new investor. The joint
venture was established to sell Engage's
                                       22
<PAGE>

products and services in Japan. This investment is being accounted for under
the equity method of accounting. Engage's share of the joint venture's foreign
currency translation adjustments is reflected in both the investment account
and in shareholders' equity as a component of comprehensive income on the
consolidated balance sheet. Under a separate license agreement, Engage licensed
its Engage Knowledge technology to the joint venture in consideration for a
non-refundable $3.0 million prepaid royalty and future royalties of 11.11% of
future revenue. The initial lump sum royalty has been deferred and is being
recognized as income over three years beginning in December 1998, the estimated
period over which Engage expects to provide maintenance and support. In
addition, Engage and the joint venture entered into a reseller agreement under
which Engage granted the joint venture an exclusive right to resell its
products to end users in Japan. Under the terms of the reseller agreement, the
joint venture is entitled to purchase Engage's products for resale to end-users
in Japan, excluding Japanese distribution rights granted to Red Brick.

   In April 1999, Engage acquired I/PRO, which provides Web site traffic
measurement and audit services, for approximately $32.7 million, consisting of
$1.6 million in net cash, $20.9 million in CMGI shares and $10.2 million in
Engage shares and options. The acquisition has been accounted for using the
purchase method, and, accordingly, the purchase price has been allocated to the
assets purchased and liabilities assumed based upon their fair values at the
dates of acquisition. Engage has recorded an expense of $4.5 million in the
third quarter of fiscal 1999 representing acquired in-process research and
development that had not yet reached technological feasibility and had no
alternative future use. Goodwill and other intangibles, totaling $27.2 million,
were recorded and are being amortized on a straight-line basis over two or five
years, depending on the asset class. In addition, CMGI must pay up to $3.0
million to I/PRO stockholders if the following performance goals are met:

  . the gross revenue of I/PRO for the year ended March 31, 2000 exceeds
    $10.8 million;

  . as of May 31, 1999 data contributed to the Engage knowledge database
    equals 65% or more of the volume of data contributed to I/PRO on the
    closing of the transaction and this data constitutes 75% or more of the
    data generated by visitors to the Web sites of I/PRO customers as of
    March 31, 2000; and

  . various employees of I/PRO are employed by Engage on March 31, 2000.

   Engage must reimburse CMGI for any such payments, at CMGI's election, in
cash or by issuance of shares of Engage common stock at its then fair market
value. Any additional payment will be treated as additional purchase price and
amortized over the balance of the two or five year period.

   Engage recorded deferred compensation of $1.7 million in 1998 related to the
Accipiter acquisition and $4.2 million for the nine months ended April 30,
1999, representing the difference between the exercise price of stock options
granted and the estimated fair market value of the underlying common stock at
the date of grant. The difference is recorded as a reduction of stockholders'
equity and is being amortized over the vesting period of applicable options,
typically four years. Of the total deferred compensation amount, $1.1 million
had been amortized as of April 30, 1999. The amortization of deferred
compensation is recorded as an operating expense. We currently expect to
amortize the following remaining amounts of deferred compensation as of April
30, 1999 in the periods indicated:

   Engage's corporate headquarters are shared with CMGI and several other CMGI
affiliates. CMGI allocates facility and services costs among these affiliates
based upon headcount within each affiliate and within each department of each
affiliate. Services provided by CMGI include support for human resources,

                                       23
<PAGE>

systems, business development and marketing. Actual expenses could have varied
had Engage been operating on a stand-alone basis. Costs allocated to Engage are
considered to equal fair market value for the facilities used and services
provided.

   Engage has incurred significant net losses and negative cash flows from
operations since its inception, and as of April 30, 1999, had an accumulated
deficit of approximately $47.6 million. Engage had net losses of $13.8 million
in fiscal 1998 and $21.2 million in the first nine months of fiscal 1999. These
losses have been funded primarily through the issuance of preferred stock and
from funds advanced by CMGI. Engage intends to continue to invest heavily in
sales, marketing and promotion, technology and infrastructure development. As a
result, Engage believes that it will continue to incur operating losses and
negative cash flows from operations for the foreseeable future and that the
rate at which such losses will be incurred may increase from current levels.

   Engage has entered into an agreement with Compaq Computer whereby Compaq
will license Accipiter AdManager, Decision SupportServer and ProfileServer from
Engage. Engage also has entered into an agreement with Compaq pursuant to which
Engage will issue Compaq prior to the closing of this offering 938,000 shares
of common stock at a purchase price of $14.00 per share resulting in
approximately $13.1 million of net proceeds to Engage.

                             Results of Operations

Comparison of the Nine Months Ended April 30, 1998 and April 30, 1999

Revenue

   Total revenue increased from $613,000 in the nine months ended April 30,
1998 to $9.0 million in the nine months ended April 30, 1999, primarily as a
result of the commencement of sales of Accipiter AdManager and AdBureau due to
the acquisition of Accipiter as well as the introduction of ProfileServer and
DecisionSupportServer. In addition, a portion of this increase is the result of
the acquisition of I/PRO and the inclusion of I/PRO's April 1999 revenue in
product revenues for the nine months ended April 30, 1999. Revenue from product
licenses accounted for approximately 85% of total revenue during the nine-month
period ended April 30, 1998, compared to approximately 87% during the nine-
month period ended April 30, 1999. Revenue from one customer accounted for
approximately 10% of total revenue during the nine months ended April 30, 1999.

Cost of Revenue

   Cost of product revenue includes royalties paid to various parties for the
incorporation of their technology into Engage's products, as well as fees paid
for outsourced data center operations and the amortization of developed
technology acquired in the Accipiter and I/PRO acquisitions. Cost of support
and services revenue is primarily comprised of payroll and benefits, and
allocated overhead costs associated with Engage's customer support,
installation and training staff.

   Cost of product revenue increased from $36,000 in the nine months ended
April 30, 1998 to $1.3 million in the nine months ended April 30, 1999. The
increase was due primarily to an increase in operational costs associated with
the introduction of Engage's AdBureau services. In addition, a portion of the
increase is the result of costs associated with the resale of a third-party
vendor's products in conjunction with Engage's product offerings. The costs
associated with such arrangements typically provide for lower margins than
Engage's other product offerings. Finally, a portion of the increase is the
result of increased amortization costs resulting from the amortization of
developed technology acquired in the Accipiter and I/PRO acquisitions.

   Cost of service and support revenue increased from $1.2 million in the nine
months ended April 30, 1998 to $4.3 million in the nine months ended April 30,
1999. Costs in both periods exceeded the related revenue due to Engage's
continued investment in service and support staff in advance of anticipated
product sales. Engage's service and support staff increased from 30 at April
30, 1998 to 63 at April 30, 1999.
                                       24

Operating Expenses

   In-Process Research and Development. In-process research and development
expense was $9.2 million during the nine months ended April 30, 1998 due to the
completion of the Accipiter transaction, compared to $4.5 million during the
nine months ended April 30, 1999 which resulted from the I/PRO acquisition.

   Research and Development. Research and development expenses consist
primarily of payroll and related costs, consulting and contractor fees,
facility-related costs, such as rent and computer and network services, and
depreciation expenses. Research and development expenses increased from
$4.7 million in the nine months ended April 30, 1998 to $5.8 million in the
nine months ended April 30, 1999. The increases were the result of the growth
of Engage's research and development activities and the inclusion of
Accipiter's operations for the entire nine-month period ended April 30, 1999,
and the inclusion of I/PRO's operations for one month in the nine-month period
ended April 30, 1999. These increases in costs were partially offset by a
decrease in facility and related costs that resulted from lower allocated costs
from CMGI due to higher utilization rates of corporate facilities and increased
staffing at other entities within CMGI.

   Selling and Marketing. Selling and marketing expenses consist primarily of
payroll and related costs, consulting and professional fees and advertising
expenses. Selling and marketing expenses increased from $2.5 million in the
nine months ended April 30, 1998 to $6.6 million in the nine months ended April
30, 1999. The increase in costs was primarily due to the continuing expansion
of Engage's sales force and the inclusion of Accipiter's and I/PRO's
operations. Engage's sales and marketing staff increased from 27 at April 30,
1998 to 66 at April 30, 1999. In addition, a portion of the increase was
related to increases in product advertising costs resulting from the release of
new products.

   General and Administrative. General and administrative costs consist
principally of payroll and related costs, consulting and professional fees,
facility and related costs and depreciation expense. General and administrative
expenses increased from $1.0 million in the nine months ended April 30, 1998 to
$2.4 million in the nine months ended April 30, 1999. The increase was
primarily due to an increase in payroll and related costs associated with the
support of growing operations as well as the inclusion of Accipiter's and
I/PRO's operations. In addition, a portion of this increase was the result of
increased professional fees incurred in connection with increased contract
activity and the formation of Engage's Japanese joint venture.

   Amortization of Goodwill and other Intangibles. Amortization of intangible
assets increased from $358,000 in the nine months ended April 30, 1998 to $3.5
million during the nine months ended April 30, 1999. The increase was primarily
due to the acquisition of Accipiter in April 1998, and to a lesser extent, the
acquisition of I/PRO in April 1999.

Stock Compensation

   Stock compensation costs increased from $65,000 in the nine months ended
April 30, 1998 to $657,000 during the nine months ended April 30, 1999.
Beginning in April 1998, Engage commenced the recognition of compensation
expense relating to approximately 173,080 shares of CMGI common stock held in
escrow to be issued to employee stockholders of Accipiter who satisfy a two-
year employment continuation provision. Additionally, stock compensation costs
of $69,000 were recorded during the nine months ended April 30, 1999 as a
result of stock options granted during 1999 with exercise prices below the
estimated fair market value of the common stock at the date of grant.

Gain on Sale of Product Rights

   Gain on sale of product rights was approximately $9.2 million during the
nine months ended April 30, 1998 as a result of Engage's sale of some rights to
its data warehouse products to Red Brick during the first quarter of fiscal
1998.

Equity in Loss of Joint Venture

   Equity in loss of joint venture was a loss of approximately $417,000 during
the nine months

                                       25
<PAGE>

ended April 30, 1999. In August 1998, Engage acquired 49% of the shares of
Engage Technologies Japan, a joint venture with Sumitomo Corporation in Japan.
Engage's ownership interest was subsequently reduced to 46% after the issuance
of additional equity in the joint venture to a new investor. The joint venture
was established to sell Engage's products and services in Japan. This
investment is being accounted for under the equity method of accounting, and as
such, Engage's portion of the joint venture's losses during the nine months
ended April 30, 1999 are included in Engage's results of operations.

Interest Expense, Net

   Interest expense, net was approximately $60,000 for the nine months ended
April 30, 1998, compared to $411,000 for the nine months ended April 30, 1999.
No interest expense was recorded during the first six months of the nine months
ended April 30, 1998. In the second half of fiscal 1998, Engage entered into an
arrangement with CMGI which requires Engage to accrue interest on intercompany
debt at a rate of 7% per annum.

Net Loss

   Net loss increased from $9.2 million in the nine months ended April 30, 1998
to $21.2 million in the nine months ended April 30, 1999. The increase was
primarily due to increased operating expenses. In addition, in the 1998 period,
Engage realized a gain of $9.2 million on the sale of certain product rights.

Comparison of Fiscal Years Ended July 31, 1996, 1997 and 1998

Revenue

   Total revenue increased from zero in fiscal 1996 to $25,000 in fiscal 1997
and $2.2 million in fiscal 1998. The increase in fiscal 1998 resulted from the
acquisition of Accipiter in April 1998, which added Accipiter's AdManager and
AdBureau products and services to Engage's product portfolio, as well as the
introduction of Engage's ProfileServer and DecisionSupportServer products. All
revenue during fiscal 1997 was derived from one customer, while revenue from
three customers accounted for 20%, 12% and 11% of revenue during fiscal 1998.

Cost of Revenue

   Cost of product revenue was 10% of product revenue in fiscal 1998. Cost of
service and support revenue exceeded services and support revenue in fiscal
1998 as Engage hired additional services and support staff throughout the year
in anticipation of increased product sales. In addition, Engage's release of
several new products during the year resulted in additional support costs to
diagnose and correct customer-specific product issues that typically occur with
the release of a new software product.

Operating Expenses

   In-Process Research and Development. In-process research and development
expense in fiscal 1998 was $9.2 million, resulting from the acquisition of
Accipiter.

   Research and Development. Research and development expenses increased from
$1.8 million in fiscal 1996 to $7.3 million in fiscal 1997 and decreased to
$5.9 million in fiscal 1998. The increase in fiscal 1997 was due to significant
increases in personnel costs associated with the continued development of new
products. The decrease in fiscal 1998 was primarily due to a decrease in
staffing that occurred when Engage sold some rights to its data warehouse
products to Red Brick at the beginning of fiscal 1998. In addition, a portion
of the decrease was the result of reassigning employees from research and
development to product support, consulting and training upon the release of
several of Engage's products in fiscal 1998.

   Selling and Marketing. Selling and marketing expenses increased from
$155,000 in fiscal 1996 to $1.6 million in fiscal 1997 and $4.0 million in
fiscal 1998. The increases were the result of significant growth in Engage's
sales force during this period, as well as increased advertising expenditures
in fiscal 1998.

   General and Administrative. General and administrative expenses increased
from $428,000 in fiscal 1996 to $1.4 million in fiscal 1997 and $2.0 million in
fiscal 1998. The increase was the result of increased payroll and related
costs, as well as increased facilities costs required to support growing
operations.

                                       26
<PAGE>

   Amortization of Goodwill and Other Intangibles. Amortization of goodwill and
other intangible assets was $1.4 million in fiscal 1998, resulting from the
acquisition of Accipiter in April 1998.

Gain on Sale of Product Rights

   Gain on sale of product rights was $9.2 million in fiscal 1998, as a result
of the sale of rights to data warehouse products to Red Brick.

Interest Expense, Net

   Interest expense, net was $172,000 in fiscal 1998. In the second half of
fiscal 1998, Engage entered into an arrangement with CMGI which requires Engage
to accrue interest on intercompany debt at a rate of 7% per annum. No interest
expense was recorded in fiscal 1997.

Net Loss

   Net loss was $2.4 million in fiscal 1996, $10.3 million in fiscal 1997 and
$13.8 million in fiscal 1998. The increase in net loss over this period was
attributable primarily to increased operating expenses.

                     Combined Historical Quarterly Revenue

   The following table sets forth unaudited combined historical revenue for the
six quarters ended April 30, 1999. Total revenue has been derived by adding the
quarterly historical revenue of Engage, Accipiter and I/PRO as if Engage had
acquired Accipiter and I/PRO on August 1, 1997. Engage acquired Accipiter in
April 1998 and I/PRO in April 1999. This data has been derived from unaudited
financial statements of Engage, Accipiter and I/PRO and
does not necessarily reflect the total revenue that would have been achieved if
Engage had acquired Accipiter and I/PRO as of August 1, 1997. This data is not
necessarily indicative of the future quarterly revenue of Engage.

                        Liquidity and Capital Resources

   Since its inception, Engage has financed its operations primarily through
funds advanced from CMGI. In addition, Engage has funded its investing
activities, specifically its acquisition of Accipiter and I/PRO, through the
issuance of its convertible preferred stock.

   Net cash used in operating activities amounted to approximately $2.0
million, $9.0 million, $10.5 million for fiscal 1996, fiscal 1997 and fiscal
1998, respectively, and amounted to approximately $7.9 million and $7.2 million
for the nine months ended April 30, 1998 and 1999, respectively. The increase
in cash used in operations has primarily been caused by increasing net
operating losses, which are partially offset by non-cash depreciation and
amortization charges included in the applicable net income or loss. In
addition, net cash used in operating activities in fiscal 1998 and the nine
months ended April 30, 1998 included a non-cash gain on sale of product rights
of $9.2 million, partially offset by the non-cash write-off of in-process
research and development costs. Net cash used in operations during the nine
months ended April 30, 1999 included approximately $2.8 million from the
increase in accrued expenses during the period, as well as $3.2 million from
the increase in deferred revenue during the period. The increase in deferred
revenue is the result of advance payments received from customers for Engage's
products.

   Net cash used in investing activities amounted to approximately $1.6
million, $490,000 and $1.2 million during fiscal 1996, fiscal 1997 and the nine
months ended April 30, 1999, respectively, while investing activities provided
$473,000 and $536,000 of cash during fiscal 1998 and the nine months ended
April 30, 1998, respectively. Investing activities used $1.6 million, $490,000,
$216,000, $153,000 and $165,000 during fiscal 1996, fiscal 1997 and fiscal 1998
and the nine months ended April 30, 1998 and 1999 to acquire property and
equipment required to support the growth of the business. Investing activities

and the nine months ended April 30, 1998 included $689,000 of net cash acquired
from the acquisition of Accipiter. Investing activities during the nine months
ended April 30, 1999 used approximately $1.4 million in Engage's investment in
a Japanese joint venture, which was partially offset by $347,000 of net cash
acquired from the acquisition of I/PRO.

   Net cash provided by financing activities amounted to approximately $3.6
million, $9.5 million, $10.1 million for fiscal 1996, fiscal 1997 and fiscal
1998, respectively and amounted to $7.9 million and $9.0 million for the nine
months ended April 30, 1998 and 1999, respectively. Cash provided in each
period was primarily related to funds advanced from CMGI to fund Engage's
operations. Cash provided by financing activities during fiscal 1997 was
partially offset by the repayment of debt of $1.0 million. Cash provided by
financing activities during the nine months ended April 30, 1999 includes net
proceeds of $1.9 million from the issuance of Series B convertible preferred
stock.

   Under an informal arrangement with CMGI, Engage has maintained a zero
balance cash account. CMGI has funded Engage's operations as needed, with a
corresponding increase in Engage's obligations to CMGI. Customer and other
receipts have been remitted to CMGI and have been applied to reduce Engage's
obligations to CMGI. The outstanding balance of Engage's obligations to CMGI at
the end of each fiscal quarter, commencing with the quarter ended January 31,
1998, have been evidenced by demand promissory notes bearing interest at an
annual rate of 7% and convertible into shares of Engage convertible preferred
stock at the fair market value of such stock as of the end of the applicable
quarter. As of April 30, 1999, there were outstanding $37.4 million in
principal amount of these notes to CMGI of which $22.1 million in principal
amount was attributable to the acquisition of I/PRO. Engage expects that it
will continue to borrow funds from CMGI under this arrangement until the
closing of this offering and that the net obligations incurred after the end of
the fiscal quarter preceding the closing, to the extent outstanding, will be
converted into Engage common stock at the initial public offering price.

   Engage has experienced a substantial increase in its expenditures since
inception
consistent with its growth in operations and staffing. Engage anticipates that
expenditures will continue to increase for the foreseeable future as Engage
accelerates the growth of its business. Additionally, Engage will continue to
evaluate investment opportunities in businesses that management believes will
complement its technologies and market strategies.

   Engage currently anticipates that its available cash resources, together
with the net proceeds from the sale of 938,000 shares of common stock to be
issued prior to the closing of this offering and the net proceeds from this
offering, will be sufficient to meet its anticipated needs for working capital
and capital expenditures for at least the 12 months following the date of this
prospectus. However, Engage may need to raise additional funds in order to fund
more rapid expansion, to develop new or enhance existing services or products,
to respond to competitive pressures or to acquire complementary products,
businesses or technologies. On a long-term basis, Engage may require additional
external financing through credit facilities, sales of additional equity or
other financing vehicles. If additional funds are raised through the issuance
of equity or convertible debt securities, the percentage ownership of Engage's
stockholders will be reduced and its stockholders may experience additional
dilution. Engage cannot assure you that additional financing will be available
on terms favorable to Engage, or at all. If adequate funds are not available or
are not available on acceptable terms, Engage's ability to fund its expansion,
take advantage of unanticipated opportunities, develop or enhance services or
products or otherwise respond to competitive pressures would be significantly
limited.

                      In-Process Research and Development

Accipiter

   CMGI acquired Accipiter on April 8, 1998 for total purchase consideration of
$31.3 million. In August 1998, Accipiter merged with Engage in a

                                       28
<PAGE>

stock-for-stock merger in which consideration of 700,000 shares of Engage
Series A Convertible Preferred Stock were issued to CMGI. The portion of the
purchase price allocated to in-process research and development was $9.2
million, or approximately 29% of the total purchase price. At the acquisition
date, Accipiter's major in-process project was the development of AdManager
version 4.0, which was intended to provide the ad serving functionality that
customers were requiring as the use of the Internet rapidly increased and
customer Web sites became more complex. In general, previous AdManager releases
did not provide for the fault tolerance, redundancy and scalability that
customers began to seek after AdManager versions 1.0 and 2.0 were released.
Accordingly, customers' long-term product needs required Accipiter to
substantially redesign the AdManager architecture to develop new technologies
to provide:

  . improved fault tolerance, which is the ability to operate during a system
    failure, and scalability, which is the ability to expand capacity,

  . an object-oriented user interface, which is a screen display that enables
    users to easily operate a computer program,

  . application programming interfaces, which enable a program to exchange
    data with other programs and

  . a new report engine, which is a component that generates reports.

   This redesigned AdManager architecture was later released as version 4.0.

   At the date of the acquisition, management estimated that completion of the
AdManager version 4.0 technology would be accomplished by June 1998. Engage
began beta testing AdManager version 4.0 at a customer site in June 1998 and
commercially released the product in August 1998. The initial development
effort had commenced in late 1997. At the acquisition date, the new AdManager
technology had not reached a completed prototype stage and beta testing had not
yet commenced. At the time of the Accipiter purchase, the AdManager version 4.0
project was approximately 71% complete.

   The value of in-process research and development was determined using an
income approach. This approach takes into consideration earnings remaining
after deducting from cash flows related to the in-process technology, the
market rates of return on contributory assets, including developed technology,
assembled workforce, working capital and fixed assets. The cash flows are then
discounted to present value at an appropriate rate. Discount rates are
determined by an analysis of the risks associated with each of the identified
intangible assets. The discount rate used for in-process research and
development was 24.5%, a slight premium over the estimated weighted-average
cost of capital of 24%, and the discount rate used for developed technology was
21%.

   The resulting net cash flows to which the discount rate was applied are
based on Engage management's estimates of revenues, cost of revenues, research
and development costs, selling and marketing costs, general and administrative
costs, and income taxes from such acquired technology. These estimates are
based on the assumptions set forth below.

   Accipiter recorded revenue in 1997 of less than $1 million. Because of the
absence of meaningful historical revenue of Accipiter, management projected
revenue for the initial year of the forecast period based on its assessment of
future market potential and the ability of Accipiter to successfully launch its
new product offering. After the initial year of the users and online activity
and the impact such growth would have on Internet advertising. These
projections are based on Engage management's estimates of the significant
growth in the number of companies engaged in e-commerce, the need for e-
commerce companies to serve ads over the Internet, expected trends in
technology and the nature and expected timing of new product introductions by
Engage and its competitors. These estimates also include growth related to the
use of Accipiter technologies in conjunction with Engage's products, the
marketing and distribution of the resulting products through Engage's sales
force and the benefits of Engage's incremental financial support and stability.

                                       29
<PAGE>

   Engage's estimated cost of sales as a percentage of revenue is expected to
be slightly lower than Accipiter's on a stand-alone basis, which was 16% in
1997, as fixed costs included in cost of sales are spread over a larger revenue
base and provide for the realization of efficiencies due to economies of scale
through combined operations. Due to these savings, the estimated cost of sales
as a percentage of revenue is expected to decrease by 1% each year from
Accipiter's historical percentage, to a low of 11% in the fifth forecast year.

   Engage's selling, general and administrative costs are expected to be higher
than Accipiter's on an absolute basis, but lower as a percentage of revenue.
Due to the small revenue base in 1997 and the impact of significant costs
associated with building a corporate infrastructure and building a workforce
for future operations, Accipiter's selling, general and administrative costs in
1997, as a percent of revenue, are not representative of the expected costs for
the combined operations of Engage and Accipiter. Efficiencies due to economies
of scale through combined operations, such as consolidated marketing and
advertising programs, are expected to be realized immediately.

I/PRO

   Engage acquired I/PRO on April 7, 1999 for total purchase consideration of
$32.7 million. The portion of the purchase price allocated to in-process
research and development was $4.5 million, or approximately 14% of the total
purchase price. At the acquisition date, I/PRO's major in-process project was
the development of a new data processing system, project name Normandy, which
is intended to provide improved functionality. In general, the existing data
processing system does not provide sufficient fault tolerance, scalability and
data processing efficiency to meet future customer needs. Accordingly,
customers' long-term product needs required I/PRO to substantially redesign the
data processing system to develop new technologies in the areas of: (1) fault
tolerance and scalability, (2) system management, (3) data capture and (4) path
analysis functionality, which is the ability to track movement of Web visitors
across Web pages.

   At the date of the acquisition, management estimated that completion of the
Normandy technology would be accomplished by August 1999. The initial
development effort had commenced in late 1998. At the acquisition date, the new
Normandy technology had not reached a completed prototype stage and beta
testing had not yet commenced. At the time of the I/PRO purchase, the Normandy
project was approximately 64% complete.

   The value of in-process research and development was determined using an
income approach. This approach takes into consideration earnings remaining
after deducting from cash flows related to the in-process technology, the
market rates of return on contributory assets, including core developed
technology, assembled workforce, working capital and fixed assets. The cash
flows are then discounted to present value at an appropriate rate. Discount
rates are determined by an analysis of the risks associated with each of the
identified intangible assets. The discount rate used for in-process research
and development was 30%, a premium over the estimated weighted-average cost of
capital of 25%, and the discount rate used for core developed technology was
22%.

   The resulting net cash flows to which the discount rate was applied are
based on Engage management's estimates of revenues, cost of revenues, research
and development costs, selling and marketing costs, general and administrative
costs, and income taxes from such acquired technology. These estimates are
based on the assumptions set forth below.

   Management projected average annual revenue increases for the forecast
period based on its assessment of future market potential and the ability of
I/PRO to successfully implement the Normandy technology. Revenue was predicted
to grow at rates comparable to the growth of Internet users and online activity
and the impact such growth would have on Internet service companies. Revenue
related to the Normandy project were separately identified.

   These projections are based on Engage management's estimates of the
significant growth in the number of companies engaged in

                                       30
<PAGE>

e-commerce, the need for e-commerce companies to utilize independent audit,
verification and analysis services, expected trends in technology and the
nature and expected timing of new product introductions by its competitors.
These estimates also include growth related to the use of certain I/PRO
technologies in conjunction with Engage's products and the benefits of Engage's
incremental financial support and stability.

   I/PRO's estimated cost of sales as a percentage of revenue is expected to
significantly decrease on a stand-alone basis, which was 85% in 1998, as
certain fixed costs included in cost of sales are spread over a larger revenue
base and provide for the realization of efficiencies due to economies of scale.
The Normandy technology is expected to greatly increase the automation of data
processing, allowing significant labor cost savings per revenue dollar.
Increases in hardware utilization are also expected. Due to these savings, the
estimated cost of sales as a percentage of revenue is expected to decrease to a
low of 20% in the fifth forecast year.

   I/PRO's operating expenses are expected to increase on an absolute basis,
but to significantly decrease as a percentage of revenue over the term of the
forecast, which was 192% in 1998. Certain fixed expenses are spread over a
larger revenue base and provide for the realization of efficiencies due to
economies of scale. Due to these savings, the estimated cost of sales as a
percentage of revenue is expected to decrease to a low of 49% in the fifth
forecast year.

                        Recent Accounting Pronouncements

   In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information". SFAS No.
131 establishes standards for the way that public business enterprises report
selected information about operating segments in annual and interim financial
statements. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. SFAS No. 131
requires the use of the "management approach" in disclosing segment
information, based largely on how senior management generally analyzes the
business operations. SFAS No. 131 has been adopted by Engage effective August
1, 1998.

   In March 1998, the Accounting Standards Executive Committee of 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". SOP 98-1 requires the capitalization of various internal costs
related to the implementation of computer software obtained for internal use.
Engage is required to adopt this standard in the first quarter of fiscal year
2000, and expects that the adoption of SOP 98-1 will not have a material impact
on its financial position or its results of operations.

   In April 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants issued Statement of Position 98-5,
"Reporting Costs of Start-Up Activities". Under SOP 98-5, the cost of start-up
activities should be expended as incurred. Start-up activities are broadly
defined as those one-time activities related to opening a new facility,
introducing a new product or service, conducting business in a new territory,
conducting business with a new class of customer, commencing some new operation
or organizing a new entity. SOP 98-5 is effective for Engage's fiscal 1999
financial statements. Engage does not expect its adoption to have a material
impact on its financial position or results of operations.

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities". SFAS No. 133
establishes accounting and reporting standards for derivative instruments,
including some derivative instruments embedded in other contracts, collectively
referred to as derivatives, and for hedging activities. SFAS No. 133 requires
the recognition of all derivatives as either assets or liabilities in the
statement of financial position and the measurement of those

                                       31
<PAGE>

instruments at fair value. Engage is required to adopt this standard in the
first quarter of fiscal year 2000, and expects that the adoption of SFAS No.
133 will not have a material impact on its financial position or its results of
operations.

                              Year 2000 Compliance

   Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. These date code fields
will need to accept four digit entries to distinguish 21st century dates from
20th century dates. As a result, many companies' software and computer systems
may need to be upgraded or replaced in order to comply with these "Year 2000"
requirements or risk system failure or miscalculations causing disruptions of
normal business activities. Engage is in the process of evaluating and
correcting the Year 2000 compliance of its proprietary products and services
and third party equipment and software that it uses, as well as its non-
information technology systems, such as building security, voice mail and other
systems.

State of Readiness

   Engage has made an assessment of the Year 2000 readiness of its operating,
financial and administrative systems, including the hardware and software that
support Engage's systems. Engage's Year 2000 compliance efforts consist of the
following:

  . identification of all software products, information technology systems
    and non-information technology systems that may be affected by Year 2000
    issues;

  . assessment of repair or replacement requirements;

  . repair or replacement;

  . testing;

  . implementation; and

  . creation of contingency plans in the event of Year 2000 failures.

   For its currently marketed software products, Engage has substantially
completed its Year 2000 compliance testing efforts and believes that its
products are Year 2000 compliant in all material respects. Engage also has
conducted less extensive testing of older versions of its products. While
Engage is not aware of any material respect in which its older products are not
Year 2000 compliant, it intends to offer customers using older products the
option to upgrade to current versions at no additional charge. Engage also has
tested and continues to test its internal and third-party provided systems that
are used to deliver customer services. Engage has received assurances from
NaviSite, a major third-party vendor, that NaviSite will be responsible for
ensuring that its system is Year 2000 ready.

   For all other systems, Engage's Year 2000 task force is currently conducting
an inventory of and developing testing procedures for all software and related
systems that it believes may be affected by Year 2000 issues. Since third
parties developed and currently support many of the systems that Engage uses, a
significant part of this effort will be to ensure that these third-party
systems are Year 2000 compliant. To date the internal evaluation has resulted
in the identification of a small number of desktop computers whose operating
systems are not Year 2000 compliant; these computers were replaced by Engage in
the third quarter of fiscal 1999. Until such testing is completed and such
vendors and providers are contacted, Engage will not be able to completely
evaluate whether its systems will need to be revised or replaced. The testing
and implementation phases are expected to be completed by the end of July 1999.

Costs

   Through April 1999, Engage has spent approximately $374,000 on Year 2000
compliance issues and expects to incur an additional $550,000 in connection
with identifying, evaluating and addressing Year 2000 compliance issues and
replacing non-compliant computer hardware. Most of Engage's expenses have
related to, and are expected to continue to relate to, the operating costs
associated with time spent by employees and consultants in the evaluation
process and Year 2000 compliance matters generally. Such

                                       32
<PAGE>

expenses, if higher than anticipated, could have a material adverse effect on
Engage's business, financial condition and results of operations.

Risks

   Engage is not currently aware of any Year 2000 compliance problems relating
to its products or systems that would have a material adverse effect on its
business, financial condition and results of operations, without taking into
account Engage's efforts to avoid or fix such problems. There can be no
assurance that Engage will not discover Year 2000 compliance problems in its
products or systems that will require substantial revision. In addition, there
can be no assurance that third-party software, hardware or services
incorporated into Engage's material systems will not need to be revised or
replaced, all of which could be time-consuming and expensive. The failure of
Engage to fix or replace its internally developed proprietary software or
third-party software, hardware or services on a timely basis could result in
lost revenue, increased operating costs, the loss of customers and other
business interruptions, any of which could have a material adverse effect on
Engage's business, financial condition and results of operations. Moreover, the
failure to adequately address Year 2000 compliance issues in its internally
developed proprietary software could result in claims of mismanagement,
misrepresentation or breach of contract and related litigation, which could be
costly and time-consuming to defend.

   Engage is heavily dependent on NaviSite to provide outsourced data services.
A significant Year 2000 related disruption of the outsourced data services that
NaviSite provides to Engage could cause customers to consider canceling
services with Engage or cause an unmanageable burden on Engage's technical
support, which in turn could materially and adversely affect Engage's business,
financial condition and results of operations.

   In addition, there can be no assurance that governmental agencies, utility
companies, Internet access companies, third-party service providers and others
outside of Engage's control will be Year 2000 compliant. The failure by such
entities to be Year 2000 compliant could result in a systemic failure beyond
the control of Engage, such as a prolonged Internet, telecommunications or
electrical failure, which could also prevent Engage from delivering its
services to its customers, decrease the use of the Internet or prevent users
from accessing its Web sites which could have a material adverse effect on
Engage's business, financial condition and results of operations.

Contingency Plan

   As discussed above, Engage is engaged in an ongoing Year 2000 assessment and
is in the process of developing contingency plans. The results of Engage's Year
2000 simulation testing and the responses received from third-party vendors and
service providers will be taken into account in adopting final contingency
plans.

                                     Engage

   Engage offers a range of products and services that enable Web publishers,
advertisers and merchants to target the delivery of advertisements, content and
e-commerce offerings to their audiences and to measure their effectiveness.
Engage has generated most of its revenue to date through sales of its
advertising management software and outsourced services, as well as its
services for measuring and analyzing Web site traffic. Engage is currently
testing its Engage Knowledge data service with customers, and plans to
implement this service on a commercial basis in July 1999. Engage Knowledge
will provide real-time access to Engage's database of more than 30 million
anonymous profiles of Web users for more effective targeting of online
advertising, promotions and content. Engage expects that a significant portion
of its future growth will be attributable to sales of subscriptions to the
Engage Knowledge data service and other products and services that will be
based upon Engage's profiling technology.

                              Industry Background

Growth of the Internet and Internet Marketing, Commerce and Analysis

   The Internet has emerged as a significant global communications medium. The
growth in the number of Web users is expected to continue as Internet access
becomes more widely available, bandwidth increases and Internet content
improves and incorporates more multimedia capabilities. International Data
Corporation (IDC) has estimated that the number of Web users worldwide will
increase from approximately 97 million at the end of 1998 to approximately 320
million by the end of 2002, representing a compound annual growth rate of 35%.

   As the Internet grows, advertisers and marketers have the opportunity to
reach broad, global audiences. Jupiter Communications has estimated that
spending for advertising on the Internet in the United States will increase
from approximately $1.9 billion in 1998 to $7.7 billion by 2002, representing a
compound annual growth rate of 42%. The Direct Marketing Association has
estimated that spending on Internet direct marketing to consumers will grow
from an estimated $224 million in 1998 to $2.0 billion in 2003, representing a
compound annual growth rate of 55%. Due to the growth in the number of Web
users, the interactive nature of the Web and the Web's global reach,
advertisers and marketers are increasing their use of the Internet to promote
their products, services and brands. In particular, the Web allows advertisers
and marketers to target an advertisement or offering to each user in real-time
and receive direct user feedback.

   The Internet also has emerged as a significant global medium for the
electronic transaction of business, or e-commerce. Forrester Research has
estimated that consumer purchases of goods and services over the Internet in
the United States will increase from approximately $8 billion in 1998 to
approximately $76 billion in 2002, representing a compound annual growth rate
of 76%. Consumers can benefit from the faster, more convenient and potentially
less expensive transactions that e-commerce can provide, while merchants can
cost-effectively reach a global audience. The Internet is also playing an
increasingly important role in facilitating offline transactions by providing
more and better information to consumers. For example, although very few
automobiles are actually sold online, Forrester Research has estimated that in
1998 approximately 2.0 million Web households, representing 13% of all new car
purchases, used the Internet to research and select a vehicle before visiting
the dealer and that 6.4 million households, representing 41% of all new car
purchases, will use the Internet prior to purchasing a vehicle by 2002. As
electronic commerce expands, traditional and Internet merchants are turning to
the Web to locate customers, advertise and market their products and facilitate
transactions.

                                       34
<PAGE>

   By knowing more about their customers and their customers' preferences, Web
publishers and merchants can improve their sites to address the interests of
their audience. The interactive nature of the Web allows businesses to gather a
wealth of information. However, there are few tools currently available that
effectively use that data to measure and analyze the activities and behavior of
Web site visitors to facilitate strategic decision making.

Increasing Demand for Targeting Capabilities

   Early Internet marketing efforts were directed primarily at placing
advertisements on the most frequently visited Web sites and pages within those
sites. As the Internet has matured, businesses have sought to improve the
effectiveness of their marketing campaigns by directing their advertisements
and promotions toward the Web users they most want to reach. By targeting
advertisements and offerings to the most relevant users, Internet marketers
seek to improve their response rates and brand awareness and reduce costs by
eliminating spending that is not directed at their intended audience.

   As marketers have become more sophisticated in their approach to marketing
over the Internet, an increasing number of advertising-supported sites have
been established, increasing the number of competitors offering advertising
impressions and exerting downward pressure on advertising prices. In March
1999, Jupiter Communications estimated that between 70% and 80% of the
advertising inventory on Web sites was unsold. Web publishers are seeking to
sell more inventory at higher rates by offering advertisers the ability to
target advertisements based on the interests and demographic characteristics of
the visitor, rather than simply the content of the page being viewed.

   Increasingly, Internet marketers are demanding a better return on
investment. Return on investment is favorably affected by either increasing
response rate or brand awareness (return) or reducing costs of advertisements
or transactions (investment). Because the response rate for Internet
advertising is typically very low, businesses that can attain even a small
absolute increase in the advertising response rate can increase their return on
investment substantially. In addition, the large number of Web users and the
global nature of the Internet can lead to inefficient spending when merchants
deliver untargeted advertisements or promotional offerings to Web users. These
merchants expect to improve their return on investment by targeting their
advertising and offerings to those Web users who meet their desired criteria.
Although marketers can indirectly target their messages by delivering
advertisements to a specific Web site or Web page, many businesses desire to
improve their return on investment further by directly targeting
advertisements, e-commerce offerings and other content using detailed data
about a visitor's preferences and demographic characteristics.

   In addition, Web publishers and merchants are seeking to increase the
frequency and duration of Web user visits to their sites to enable them to sell
more advertising inventory and increase e-commerce revenue. By customizing the
content of Web pages to reflect users' interests and preferences, Web
publishers and merchants are seeking to attract more traffic to their Web
sites, increase visitor loyalty and improve the appeal of their e-commerce
offerings.

The Need for Solutions to Distinguish Web Users While Respecting Their Privacy

   The Web offers the potential for Web publishers, advertisers and merchants
to better understand their respective audiences and to capitalize on the
individual targeting capability, real-time feedback and other marketing
advantages offered by the Internet. Significant information about Web site
visitors can be derived from an analysis of:

  . the Web sites and page views selected by users;

  . the pattern in which users move from one site or page to another;

  . the duration of a user's visit to a site or page;

                                       35
<PAGE>

  . the purchasing and other activities of users while at a Web site; and

  . the responses of visitors to specific advertisements and promotions.

   While the Internet offers the opportunity to collect a wide variety of
information that could be used to improve audience targeting, Web users are
increasingly concerned about the potential for loss or abuse of their privacy.
Although Web site visitors can obtain significant benefits from a Web
publisher's or merchant's ability to personalize content and target e-commerce
offerings based on the user's tastes and preferences, many consumers do not
want specific identifiable information about themselves, such as their name,
home or e-mail address, made available to third parties.

   To balance the desires of marketers and consumers, there is a need for a
solution that will enable Internet marketers to tailor offerings effectively to
each user while at the same time preserving the privacy and anonymity available
to individuals on the Internet.

                              The Engage Solution

   An Engage profile is an anonymous collection of information about an
individual Web user's consumer interests, demographic characteristics and
geographic location. These profiles are developed through a combination of a
user's browsing behavior on participating sites on the Internet and information
the user has voluntarily declared at these sites, such as information provided
on an online registration form. Each anonymous profile omits information that
would permit the personal identification of the user, such as name, address and
e-mail address.

   Based on its proprietary technology, Engage has built a database containing
more than 30 million anonymous consumer profiles, which it has created from
data drawn from multiple, diverse Web sites. Customers can use these profiles
to target relevant advertisements, content and e-commerce offerings to
individual Web users based on each user's particular preferences, demographic
characteristics and geographic location.

   Engage's profiling technology can create local and global user profiles.
Local profiles, which are created and maintained by Engage's customers, contain
data derived from the customer's own Web site and typically map preferences
based on particular interest categories designed by the customer and
demographic characteristics. Global profiles, which are compiled from data
contributed to the centralized Engage Knowledge database from the Web sites of
all participating Engage customers, are provided to customers on a subscription
basis and provide a broader and more detailed description of users' interests.
These global profiles do not contain personally identifiable information of
individual users, such as name, home or e-mail address, IP address or domain
name.

   Each Engage global profile contains a series of numerical scores reflecting
each Web user's inferred preference level in hundreds of standard categories
and subcategories, such as books, business, computers, fashion, sports and
travel as well as demographic and geographic information. Categories can be
further customized to meet the needs of a specific customer or market. Engage
software uses sophisticated proprietary algorithms and methodologies to
continuously update and refine these global profiles based on a visitor's
browsing behavior across multiple Web sites, including pages selected by the
user, the duration of the user's visits and the responses of the user to
specific advertisements and promotions. Engage global profiles also incorporate
anonymous demographic and geographic information reported voluntarily by a
visitor, such as data from an onsite registration form.

   When a user visits a Web site of any customer subscribing to the Engage
Knowledge data service, Engage matches that visitor with his or her profile in
the global profile database. The profile is transmitted in real-time to the
subscribing Engage Knowledge customer site, which can then use the profile to
target advertisements, content and e-commerce offerings to that visitor. Based
on past user behavior at other Web sites, an Engage customer can determine the
interests and tailor the experience of even first-time visitors to its Web
site.

                                       37
<PAGE>

   Engage believes that its profiling technology provides a significantly more
meaningful picture of Web user preferences than other available targeting
solutions because:

  . Engage builds and constantly updates its profiles based on a user's Web
    browsing behavior, resulting in more detailed and current profiles than
    could be created with registration or other declared data only;

  . Engage profiles classify visitor information across hundreds of interest
    categories and subcategories, allowing Web publishers, advertisers and
    merchants to identify more precisely their target audience;

  . Engage global profiles are developed from data gathered from many diverse
    Web sites, generating more detailed and comprehensive information about
    Web users than could be gathered from any single site; and

  . The Engage Knowledge database currently contains more than 30 million
    user profiles, enabling the use of targeting applications for a
    significant proportion of Web site visitors.

   Engage believes, based on preliminary results of a study conducted for
Engage by a market research organization, Ipsos-ASI, that the use of Engage
profiles to target advertisements can achieve click-through rates greater than
those achieved by untargeted advertisements. Click-through rates represent the
proportion of viewers who click on an advertisement. Engage also believes,
based on this study, that the use of Engage profiles to target advertisements
on Web pages whose content is unrelated to the advertisement can achieve
click-through rates comparable to those achieved by the targeting of
advertisements based on the content of the Web page.

   Engage profiles are designed to work with other Engage applications, third-
party software or customers' internally developed solutions, allowing
customers flexibility as the uses of profiling and related applications
develop and evolve.

might contain:

   Building upon its profiling capabilities, Engage offers the following
profile-based marketing solutions:

Targeted Delivery of Advertising

   Engage's advertising management software and services allow Web publishers
and advertising networks to target advertising campaigns using either local
profiles or global profiles from the Engage Knowledge data service. Engage also
offers a turnkey outsourced advertising management service that allows Web
sites to gain the advantage of profile-based advertising without making a
significant upfront investment of cash and personnel. By allowing advertisers
to target advertisements based not only on the content of the Web page being
viewed, but also on the visitor's profile, these advertising solutions are
designed to enable Web publishers and advertising networks to sell more of
their advertising inventory and to allow advertisers to improve their return on
investment. Engage's advertising management products, when used in conjunction
with its profiling products and services, can schedule and serve advertisements
in real-time while simultaneously optimizing the impact of a message by, for
example, showing a minivan advertisement to a visitor interested in family
subjects and a sport utility vehicle advertisement to an outdoor enthusiast. In
addition, if it is known that a user is a likely minivan buyer, specific ads
can be served when the visitor is in an unrelated site or section of a site.

Targeted Delivery of Content and Commerce Offerings

   Engage's profiling software and global profiles allow Web publishers and
merchants to customize the content of Web pages and target e-commerce offerings
and promotions based on each individual user's interests. By providing Web site
visitors information that is more relevant to them, Web publishers and
merchants can strengthen visitor loyalty and increase the likelihood that a
visitor will stay at the site and make a purchase. A Web site focusing on music
can dynamically alter a Web page to present, for example, a special offer on a
jazz CD only to those visitors whose profiles indicate strong interests in jazz
and offer a different promotion to visitors with classical music interests.

Web Site Traffic Measurement, Auditing and Analysis

   Engage's analysis and traffic measurement products and services allow Web
publishers and merchants to collect, manage and analyze data about visitors and
their behavior. By analyzing how users behave and react to specific
advertising, pages or specific content areas, Web publishers can better
understand their visitors and improve the effectiveness of their Web sites.
Engage offers a range of solutions, from a basic outsourced reporting service
to sophisticated software enabling analysis of large amounts of data. Engage
also offers a comprehensive range of auditing services, including total site
traffic audits and internal reporting verification. Engage's auditing services
allow Web publishers to provide advertising buyers with the standardized
verification from an independent third party that these buyers increasingly
require before they will purchase Internet advertising inventory.

                                    Strategy

   Our objective is to enhance our position as a leading provider of profile-
based Internet marketing solutions for Web publishers, advertisers and
merchants. Our strategy to achieve this objective includes the following key
elements:

Establish Engage as a Recognized Brand for Internet Profiling

   We believe that we have the opportunity to establish Engage as the
recognized brand for profile-based marketing solutions on the Internet. To
capitalize on this opportunity, we are creating a family of "Engage-enabled"
products and services that incorporate our profiling technology to serve a
broad array of customer targeting needs on the Internet. Expanding from the
initial use of our profiling technology in targeting the delivery of
advertisements through our Accipiter advertisement management software, we plan
to integrate our profiling technology with our I/PRO market intelligence
services so that customers can better measure and analyze audience

                                       39
<PAGE>

behavior at their Web sites. We also plan to develop solutions that will allow
Web publishers, advertisers and merchants to more effectively reach customers
in specific markets, such as automotive and retail and other industry-specific
markets. By implementing our solutions across a broad spectrum of customers and
customer applications, we will seek to establish our profiling technology as
the most widely-used platform for the targeting of advertisements, content and
e-commerce offerings on the Web.

Offer Multiple Products Based on Open Standards

   We offer multiple products and services based on open standards that
facilitate the use of Engage's solutions with third-party applications. For
example, our customers can use Engage Knowledge to target advertisements in
conjunction with either our own Accipiter products or advertising management
software provided by other vendors. By enabling customers to choose
applications from third-party vendors, we believe we will be able to broaden
the market for Engage-enabled solutions and increase the quantity and quality
of the profiles compiled in the Engage Knowledge database.

Applications" and within this box are subheadings labelled "Advertising
Delivery", "Content Publishing" and "E-Commerce Server". This box has arrows
immediately above it pointing toward three boxes labelled "Targeted Ad",
"Personalized Content" and "Customized Offer".]

Continue to Enhance Engage Global Profile Database

   Each user visit to the Web site of a participating subscriber to the Engage
Knowledge data service contributes to the depth of the global profile database
and enhances its value to all customers. We will continue to increase the
quality and usefulness of Engage Knowledge profiles by:

  . expanding the number of consumer profiles through an increase in our
    installed base of subscribers and contributors to the Engage Knowledge
    data service;

  . developing new profiling algorithms to glean additional knowledge about
    Web users from data compiled for each profile; and

  . refining our interest categories and subcategories to provide more
    detailed and market-specific user profiles.

Focus on Specific Markets

   We plan to develop and sell specific Internet marketing solutions for
different markets. We are initially focusing on Web publishers and advertising
networks that derive revenue from advertising on the Web. For this market, we
are enhancing our Accipiter advertising management software and services to
allow Web publishers and advertising networks to use global profiles to
optimize utilization of their advertising space. In addition, we will seek to
increase our customers' advertising revenue by allowing them to offer a new
program to advertisers in which an advertiser will pay for the delivery of
advertising impressions only to those Web site visitors whose Engage profile
matches designated criteria. Our fees for this program will consist of a
portion of the advertising revenue generated when one of our profiles is used.

   We also plan to focus on the automotive and retail and other industry-
specific markets. For each market, we plan to develop and market tailored
versions of our Engage Knowledge database that will measure interest levels in
categories specific to those markets. For the automobile market, we will work
with key automotive sites to capture specific and detailed information about
automotive users presently in the purchase cycle and to provide manufacturers
the ability to study consumer preferences for specific automobiles or features.
For the retail market, we will continue to refine geographic-targeting

                                       40
<PAGE>

capabilities so that national retailers can address specific needs and
preferences within each local audience through the Internet.

   We also will aggressively pursue distribution arrangements with companies
that install and integrate hardware and software systems for third parties and
with independent software vendors who can deploy our profiling technologies for
specific markets. Through these indirect channels, we will seek to extend the
deployment of Engage technology and expand our customer base.

Offer Family of Engage Products and Services

   We will seek to increase our sales to our installed base of customers by
offering a range of software and services that utilize common Engage profiling
technology. For example, if a customer uses Accipiter AdManager software to
deliver Web advertisements, we will seek to sell a subscription to the Engage
Knowledge data service to enable the customer to improve advertising response
rates and brand awareness. We may also offer the customer a subscription to our
I/PRO services to measure and better understand visitor behavior. Using our
complementary line of software and services, a customer can rely upon Engage
Knowledge profiles to perform a wide range of functions and thus avoid the time
and expense otherwise required to collect, process and store large volumes of
user data multiple times for multiple functions.

Maintain Position as Advocate for Internet Privacy

   We believe that concerns about loss of privacy are increasingly important to
Internet users and therefore have designed the Engage Knowledge database with
the goal of being a leader in the protection of the privacy of individuals. We
have been an active participant in the establishment of technology, industry
and regulatory frameworks for Internet privacy and plan to continue to be
aggressive in promoting our commitment to privacy.

Expand into International Markets

   We currently market our products and services worldwide through a sales
office in London, our U.S. headquarters and through a joint venture in Japan
established with Sumitomo in July 1998. In addition, we plan to open an office
in Germany in 1999. As of April 30, 1999, we had 22 customers in Europe and
seven elsewhere outside the United States. We plan to expand our penetration of
the international market primarily through joint ventures with partners abroad.

                             Products and Services

   Engage offers a range of software and services that enable Web publishers,
advertisers and merchants to target and deliver advertisements, content and e-
commerce offerings to their audiences and to measure their effectiveness.


Engage Knowledge Data Service

   The Engage Knowledge data service uses a database which contains user
profiles collected from participating sites across the Web. Engage's database
has been designed to create, refine and deliver millions of profiles in real-
time to meet the demands of multiple Web sites. The global profiles used in the
delivery of the Engage Knowledge data service omit personally identifiable
information of individual users such as name, home or e-mail address, IP
address or domain name. The database assigns a computer-generated identifier to
distinguish each Web visitor. This identifier is currently stored as a browser
cookie on the Web user's computer. This Engage Knowledge identifier is
correlated with site-specific identifiers using a proprietary technique called
"dual blind" identification. This technique protects the privacy of the
individual because the participating Web site cannot access the Engage
Knowledge identifier and Engage does not maintain any personally identifiable
information that may have been gathered at the Web site.

   Engage Knowledge global profiles contain a series of numerical ranking
codes, as well as demographic and geographic information, with

                                       41
<PAGE>

scores that indicate the level of the consumer's interest in a category or the
accuracy of a demographic or geographic attribute. The categories are
hierarchical, with the top level representing a broad interest area such as
"Books", and lower levels representing increased specificity, such as
"Children's Books". Engage also maintains demographic and geographic
information for each profile by using computer algorithms that infer
demographic characteristics or geographic locations based on Web browsing
behavior at participating sites and by using declared information reported
voluntarily by the visitor, such as data provided by a user on an online
registration form. Engage does not retain any of the personally identifiable
information that may have been provided on the registration form, and therefore
the identity of the Web user cannot be derived from the information contained
in the global profile. Each Web page at a customer site is classified to
indicate the interest categories that will be attributed to visitors to that
page.

   When a user visits a Web site of any customer subscribing to the Engage
Knowledge data service, Engage matches that visitor to his or her profile in
the global profile database. The profile is then transmitted in real-time to
the subscribing Engage Knowledge customer site, which can then use the profile
to target advertisements, content and e-commerce offerings to that visitor.

   As a Web visitor browses through any Engage-enabled Web site, Engage's
software dynamically updates and refines the profile of that visitor based on
the recency, frequency and duration of the consumer's browsing behavior in each
interest category. The Engage Knowledge database can be integrated with third-
party data sources, such as geographic databases, to further enhance the
consumer profiles. Unlike profiles based solely on static registration data,
Engage Knowledge profiles are constantly changing to more accurately reflect
the current interests of an individual.

   Engage Knowledge profiles can be used to enhance third-party software
applications by providing targeting capabilities. These applications include
advertising management, content delivery and e-commerce offerings. Engage
provides software tools and services to facilitate the integration of Engage
Knowledge profiles with these third-party applications.

   An Engage Knowledge subscription is combined with a license to the Engage
software modules necessary to identify visitors, collect and transfer behavior
records and access profile information. Periodic subscriptions are usually
offered on a quarterly basis and the fees vary depending on traffic to the
customer's site and the application with which the service is used. Engage
expects that fees in the future will also vary based on the number of profiles
used. Engage believes that most customers will contribute their clickstream
data to the Engage Knowledge data service in exchange for reduced subscription
rates and to enhance the quality of future global profiles. Although data
contribution is not required, customers who do not contribute their site
clickstream data to Engage Knowledge are required to pay significantly higher
fees for use of the Engage Knowledge profiles. Monthly fees can range from a
few thousand dollars for a low volume Web site to hundreds of thousands of
dollars for a large customer with multiple Web sites.

   In March 1999, Engage introduced GeoKnowledge, a data service that features
multiple types of geographic data combined with profiles from the Engage
Knowledge database.

   As of April 30, 1999, Engage had implemented the Engage Knowledge data
service with customers on a test basis. Engage expects to implement the Engage
Knowledge data service on a commercial basis in July 1999.

Engage ProfileServer

   Engage ProfileServer software collects Web visitor behavior data at the
customer's Web site and declared user information reported voluntarily by a
visitor to create and deliver profiles of individual Web site visitors. The
system enables customers to create their own local profile database, which is
maintained at the customer's site, and to use these local profiles to target
advertisements, content and e-commerce offerings. The ProfileServer system
                                       42
<PAGE>

permits customers to customize the interest categories in the local profiles so
that they track preferences specific to the customer's market. For example, a
clothing retailer could create size and style subcategories. Customers can also
use the system to collect proprietary user data, including identifying
information supplied voluntarily by visitors to their sites. The local
databases created with ProfileServer, which do not become part of the Engage
Knowledge database, can be used by customers either alone or in conjunction
with the Engage Knowledge data service.

   ProfileServer is offered to customers under perpetual or annual subscription
licenses with fees that vary based on the volume of visitor activity on the
customer's sites. ProfileServer software typically ranges in price from $12,000
for a basic configuration at a small Web site to up to $100,000 for a complete
feature installation at a high volume site.

Online Advertising Systems and Services

   Engage's Accipiter ad management systems and services are designed to manage
and deliver advertising and direct marketing promotions on individual Web sites
and networks of Web sites.

   Accipiter AdManager. Accipiter AdManager automates online advertising
management for Web sites by scheduling and targeting ads, automatically
rotating ad inventory and generating up-to-the-minute, customized reports.
AdManager tracks all active advertising campaigns and Web site visitors and
optimizes scheduling of advertisements in real-time to ensure that each
campaign is delivered on schedule to qualified visitors or to the specified
content areas of a site.

   AdManager allows sites to deliver relevant advertising to individual
visitors using a wide range of targeting criteria, including:

  . Engage global and local profiles;

  . area of content that a visitor is viewing;

  . geographic location of users;

  . key-word or key-phrase searches; and

  . time of day or day of week.

   AdManager provides versatile easy-to-use scheduling features. Advertisements
within a campaign can be scheduled by the total number of impressions or
clicks, by specific time frames specified by the advertiser or any combination
of counts and date ranges. The campaign reservation system can lock in portions
of available inventory for upcoming campaigns.

   Customers can access a variety of reports to see how well a campaign is
performing. Reports can detail, for example, how many impressions and clicks
were generated both from the entire site and by each ad and advertiser.
AdManager also enables customers to securely assign access privileges for
specific functions or information to a variety of users at different levels
from different organizations. For example, a single system can provide
different levels of access to advertising agencies, web site advertising sales
representatives, and third party advertising sales representatives. AdManager
can be distributed across multiple servers to expand ad serving capacity and
provide high availability to handle the volume requirements of the largest Web
sites.

   AdManager is offered to customers under perpetual licenses or annual
subscription licenses, with fees that vary based on the number of
advertisements served. A typical AdManager installation ranges in cost from
$12,000 to more than $100,000, with an additional monthly fee for access to the
Engage Knowledge database.

   Accipiter AdBureau. Accipiter AdBureau is Engage's turnkey, outsourced
advertisement management service based on AdManager technology. By subscribing
to AdBureau, a customer can obtain the advertisement management capabilities of
AdManager without the need to invest in on-site and management hardware, server
and administrative software or databases.

   AdBureau is marketed primarily to start-up and mid-sized Web sites, as well
as advertising networks. AdBureau is offered to customers under an annual
agreement providing for fees based on the number of advertisements served, with
a $3,500 one-time set up fee and monthly fees based on the number of
advertisments

                                       43
<PAGE>

served, ranging from $1,000 per month for the smallest Web sites to more than
$15,000 per month for high volume sites.

Web Site Traffic Measurement, Auditing and Analysis

   Engage offers products and services that provide Web site traffic
measurement and analysis and verification of site traffic and advertising
results. Through its I/PRO services, Engage currently measures over seven
billion page views per month across over 350 Web sites.

   I/PRO NetLine. I/PRO NetLine is an outsourced traffic measurement service
that continuously measures Web site traffic and delivers results on a daily
basis to the customer. This service enables customers to access reports
immediately, combine data from multiple sites and standardize information for
meaningful comparisons. I/PRO provides a wide range of standard reports and
enables users to customize their reports and the data to be tracked. I/PRO
provides standard reports that contain key data about traffic at a Web site,
including information about the number of users to visit a Web site, the
duration of user visits and the most frequently visited pages of the site.
Customized reports can include information regarding specific pages,
directories and clicks and other in depth data. I/PRO NetLine is priced based
on the volume of traffic at the sites being measured and the number of reports
that are requested, and fees typically range from $2,500 to $5,000 per month.
I/PRO also offers extensive support by professional service account managers
and custom research capabilities.

   Engage plans to offer I/PRO NetLine in conjunction with Engage Knowledge
services for global audience analysis. Using profile information from the
Engage Knowledge database, customers of I/PRO NetLine will be able to customize
reports to include more detailed and comprehensive user information, which will
enhance the I/PRO NetLine traffic measurement service.

   Nielsen I/PRO I/Audit. Nielsen I/PRO I/Audit outsourced services include
audits of circulation on total audience, specific advertisements or advertising
campaigns, internal management systems and co-operative marketing arrangements.
Nielsen I/PRO I/Audit verifies information directly at the specific Web site
rather than relying on a sample from a panel or other indirect methods. Engage
believes that I/PRO was the first company to offer Web site specific audits of
Web site traffic and advertising campaigns. Engage believes that over 70% of
the 50 most visited sites currently use Nielsen I/PRO I/Audit. Nielsen I/PRO
I/Audit reports are guaranteed to be delivered within ten days of I/PRO's
receipt of the necessary data. Nielsen I/PRO I/Audit services are priced based
on the volume of traffic at the sites being audited and fees typically range
from $2,000 to $4,000 per month. I/PRO has a co-branding and reselling
agreement with Nielsen Media Research and pays royalties to Nielsen on sales of
I/PRO services.

   I/PRO Research Services. I/PRO offers custom consulting services to help
clients meet their Web marketing goals. These services combine analysis of Web
audience data with customized research. Consultants produce in-depth reports
and detailed analyses that allow customers to measure audience behavior,
monitor results against strategic objectives and more effectively manage their
Web strategies. Clients contract for research services on a project basis or at
a stated daily rate.

   Engage DecisionSupportServer. Engage DecisionSupportServer is a data
warehouse management and analysis solution that is implemented at the
customer's site. DecisionSupportServer supports a complex, visitor-focused
marketing analysis of Web site usage details and profiles. Web marketers can
monitor standard Web site usage and visitor reports or use Engage's Web
marketing analysis application to answer critical and sophisticated business
questions about visitors, their behavior and their profiles. For example, a
marketer could configure DecisionSupportServer to determine the percentage of a
Web site's repeat visitors who initially visited the Web site from the major
portal sites and who have an interest in sports. DecisionSupportServer can be
used in conjunction with a variety of decision support applications from
Business Objects and other
                                       44
<PAGE>

data warehousing vendors. In addition, customers with unique requirements can
retain professional services from Engage or one of its system integration
partners to customize the data warehouse.

   Engage DecisionSupportServer is offered to customers under perpetual
licenses or annual subscriptions with fees that vary based on the volume of
visitor activity on the customer's sites. Engage customizes and operates
DecisionSupportServer in-house for specific market segments and customer-
specific analytic consulting engagements. The license fee for
DecisionSupportServer typically ranges from $40,000 to more than $100,000.

   Engage Knowledge Research Services. Engage plans to offer Engage Knowledge
Research Services, consisting of custom analysis, research and consulting
services that use information contained in Engage's profile database. Using
this service, customers can obtain analysis of Web-wide user behavior to
identify emerging trends.

professionals as of April 30, 1999, assists customers in implementing,
administering and maintaining Engage products and services.

   Professional Services. Engage's team of service professionals provides
customers with consulting services, project implementation and integration
services and training. Engage's service professionals assist customers with
strategic site assessments and deployment planning in order to optimize each
customer's use of Engage products. These professionals also help customers
implement Engage products and integrate them into the customer's existing
technology infrastructure. Engage's professional services are generally billed
at a daily rate for each consultant employed on a project.

   Maintenance and Support Services. Engage provides maintenance and support
services to customers pursuant to annual maintenance agreements. These services
include software version updates and maintenance, as well as telephone and on-
site support. Engage provides regular functional releases to its customers, as
well as maintenance releases as needed. Engage offers a variety of support
services, including "help desk" telephone support on a 14 hours per day, five
days per week basis and a dedicated technical support Web site on a 24 hours
per day, seven days per week basis. Engage's maintenance and support activities
are supplemented by training programs for customers, including introductory
training courses for new users and custom designed seminars for experienced
users of Engage products.

   Engage's annual fees for maintenance and support services are based on a
percentage of the list price for the customer's software license fee, typically
ranging from 18% to 25%. To date, substantially all of Engage's customers have
entered into maintenance contracts.

                                   Customers

   Engage licenses its software products to Web publishers and merchants for

   The following customer case studies illustrate the selection, use and
implementation of Engage products and services by three customers that Engage
believes represent typical customers for its products.

Ancestry.com -- Profile Based Advertising and Analysis

   Ancestry.com, an affiliate of CMGI, is a comprehensive genealogy resource on
the Web, providing users with a large online repository of family and historic
data. Site visitors have free access to genealogical records online. For a
nominal fee, subscribers have complete access to the site's 1,500 databases.

   Ancestry.com needed a set of integrated tools for the analysis of Web
traffic collected at its site, user profiling and ad management to enhance the
online experience for site visitors and to increase the effectiveness of
promotions and advertising at its site. Specifically, the site wanted to
understand more about its visitors, convert unregistered visitors to registered
visitors and deliver personalized advertising to its online audience.
Ancestry.com installed Engage Accipiter AdManager advertising management
software to serve online ads and intends to deliver personalized offers through
Engage ProfileServer. To expand its targeting capabilities beyond site-specific
customer information, the site has also subscribed to the Engage Knowledge data
service. In addition, Ancestry.com is installing Engage DecisionSupportServer,
Engage's strategic market intelligence tool, to analyze the collected local
profile data, and uses the Nielsen I/PRO I/Audit services for third-party
verification of its site traffic data.

   Through the use of Engage products and services, Ancestry.com will own a
growing proprietary database of local user profiles which it expects will
enable it to better understand the behavioral patterns of its online visitors.
Ancestry.com plans to use the Engage Knowledge data service to deliver targeted
advertising to its online audience.

Ticketmaster -- Profile Based Targeting of Electronic Commerce and Content

   Ticketmaster Online is an automated ticketing services company. Ticketmaster
uses Engage ProfileServer to personalize online retailing based on declared
profiles and to target advertising based on both declared and observed behavior
online. In July 1998, Ticketmaster was seeking to address the personalization
requirements of its MyTicketmaster site, and needed a solution that
permitted profiles to drive other vendors' personalization applications.
Ticketmaster selected Engage because it offered application-independent
profiling technology that could meet its targeting requirements. Engage worked
with Ticketmaster to integrate a third party's content management application
with Engage's ProfileServer software. Ticketmaster currently
                                       46
<PAGE>

has plans to integrate another third party's advertising managment system.
Engage ProfileServer software captures registration details at the
MyTicketmaster area of the site and the clickstream behavior of visitors
throughout its site. Engage ProfileServer creates user profiles based on
declared and behavior data and maintains them in a centralized proprietary
repository for visitor data. In addition, Ticketmaster installed Engage's
DecisionSupportServer strategic market intelligence tool to analyze the
collected data.

   With its growing proprietary database of local user profiles, Ticketmaster
expects to be able to enhance the online experience of its repeat site visitors
by recommending events and providing customized offers that appeal to them
individually, thereby increasing the revenue potential of its site.

Weather.com -- Web Site Traffic Measurement, Auditing and Analysis

   Weather.com is the online arm of The Weather Channel. Weather.com uses I/PRO
NetLine to increase advertising revenue, to make resource allocation decisions
and to drive strategic partnerships. By understanding the total circulation of
different areas of the site, weather.com is able to charge a premium for high
traffic areas. I/PRO NetLine reports user requests for weather information by
zip codes allowing weather.com to sell these impressions as highly targeted
advertising opportunities at a premium. I/PRO NetLine's ability to report
activity at the most detailed level facilitates resource allocation decisions
by allowing weather.com to understand the resources required to maintain
different parts of its site and the revenue each part generates. Weather.com
also uses I/PRO NetLine to help assess the opportunities for marketing
relationships that will increase traffic at its site and to monitor the
performance of these arrangements on an ongoing basis.

   Weather.com also subscribes to the monthly Nielsen I/PRO I/Audit. The audit
report is used in sales presentations to existing and new advertisers to prove
traffic volumes and campaign results.

                              Sales and Marketing

United States

   Our sales and marketing strategy in the United States is to sell:

  . directly to prominent Web publishers, large advertisers and Web site
    networks;

  . through original equipment manufacturer, reseller and co-marketing
    arrangements to reach other customers; and

  . through Web design and systems integration firms.

   As of April 30, 1999, our sales and marketing organization consisted of 66
employees. Our field sales organization is supported by sales representatives
and systems engineers located throughout the United States. Sales
representatives handle incoming calls, help generate qualified leads and
generally advance the sales process. Systems engineers provide comprehensive
pre-sales technical services and support, including creating and delivering
technical and architectural presentations, product demonstrations and product
training, as well as post-sales telephone support, problem escalation
management, patch distribution and publication of technical notes. Our sales
and marketing employees are located in Andover, Massachusetts; Raleigh, North
Carolina; Redwood City, California; and San Francisco, California.

   The sales teams for our Accipiter ad management systems and I/PRO services
are organized as dedicated groups focused on sales in specific geographic
regions. A subset of the sales force for Engage Knowledge and Engage profiling
products are targeted to specific industry groups, thereby enabling them to
develop an in-depth understanding of the evolving needs of a particular
industry and the Web publishers, advertising networks and Web sites focused on
that industry. In addition, each sales force identifies cross-selling
opportunities for other Engage products.

   An important element of our sales strategy is to form business relationships
with third parties to assist us in marketing and selling our

                                       47
<PAGE>

products. We will seek to enter into original equipment manufacturer
relationships that permit us to embed our software products within products
sold by other vendors, such as e-commerce and Web serving software and hardware
systems. In addition, some of our indirect sales channels will consist of
either reseller arrangements, in which our partner resells and possibly
customizes our products, or co-marketing arrangements, in which we will work
together with our partner to promote and generate sales referrals for each
others' respective products. We also expect to develop relationships with
Internet systems integrators who often recommend advertising and marketing
management and other Internet solutions to their clients as part of their
design, procurement and deployment work.

   To support our sales efforts and actively promote the Engage brand, we
conduct comprehensive marketing programs, including public relations, print
advertisements, online advertisements, seminars, trade shows and ongoing
customer communications programs.

International

   We maintain a sales office in London and expect to open an additional office
in Germany in 1999. We intend to expand our operations outside the United
States primarily by partnering with locally-based third parties, including
entering into joint ventures and distribution arrangements. We have formed a
joint venture for the Japanese market with Sumitomo Corporation. As part of
this joint venture, Sumitomo markets a Japanese language version of Engage
software products and the Engage Knowledge data service throughout Japan.

                                    Privacy

   The Web offers the potential for privacy by allowing parties to communicate
one-to-one without knowing each others' identity. However, Web users are
increasingly concerned about privacy and the ability of third parties to gather
personal data about them from their activities on the Web. For this reason, the
Engage Knowledge global database of profiles does not store personal
information of individual users such as name, home or e-mail address, IP
address or domain name.

   We maintain this level of privacy through a proprietary methodology known as
"dual blind" identification. We assign an anonymous numerical identifier to
each Web visitor and match this "blind" identifier only with information
relating to online usage of a specific computer and do not store or otherwise
use any personally identifying information. This identifier is currently stored
as a browser cookie on the Web user's computer. Each Web visitor also is
assigned a different identifier for each Engage-enabled Web site visited. This
technique is known as "dual blind" identification because a Web site does not
have access to the Engage Knowledge identifier and cannot correlate the
information it may have with information from other Web sites. Conversely, we
do not maintain any information identifying particular users that a Web site
may have correlated with a visitor's local Web site identifier.

   We also protect Web user privacy by contractually prohibiting Web sites
subscribing to Engage Knowledge from using global profiles other than for the
purpose of tailoring the experience of the visitor. Customers may not store the
information, correlate it to personal information or use it to try to infer the
physical identity of the visitor. In addition, since October 1998, Engage has
required all contributors to Engage Knowledge to post a privacy policy
statement on their Web sites disclosing that the site provides non-personally
identifiable information to Engage. The policy statement must include a link to
the Engage Web site where a Web user may opt out of the Engage Knowledge
database by clicking on a link that automatically replaces the Engage Knowledge
identifier on the user's computer. We believe that these protections and our
dual blind identification technology are essential to allow sites to
responsibly use global anonymous profiles for their own enterprise
applications.

   We actively participate in the development of privacy standards for the
Internet and are a key contributor to industry groups that are developing
industry standards for privacy. For example, we are a co-author of several of
the specifications of the World Wide Web Consortium's Platform for Privacy
Preferences Project, supported by AOL/Netscape, AT&T, IBM, Microsoft and
others, which seeks to

                                       48
<PAGE>

develop an industry standard that will allow Web users to express their privacy
preferences about the type and amount of information they are willing to share
with Web applications. We believe our products will support the standards that
are ultimately produced by this project. We have also authored a proposed
protocol for the distribution of privacy labels for Web cookies as part of
privacy standards developed by the Internet Engineering Task Force. We are a
participant on the board of advisors of TRUSTe, of which we are a corporate
sponsor. TRUSTe is a non-profit organization with the goal of promoting the
adoption of fair information practices on the Web through a program which
permits Web sites to display a seal representing compliance with TRUSTe privacy
guidelines. Engage is also a member of the Online Privacy Alliance, which is an
organization dedicated to improving the protection of individuals' privacy
online through self regulatory efforts. We actively monitor proposed privacy
laws and regulations and seek to comply with all applicable privacy
requirements, both in the United States and throughout the world.

                            Operating Infrastructure

   Engage's operating infrastructure has been designed to support the combined
volumes of its largest Web site customers. Engage's data center operations are
provided by NaviSite, an affiliate of CMGI, and are located in Andover,
Massachusetts. Engage's infrastructure is designed for maximum reliability,
including redundant network access, backup power pools and advanced network
security. NaviSite provides comprehensive facilities management services,
including monitoring and support 24 hours per day, seven days per week.

   Engage operations are run by a variety of Sun Enterprise servers of various
sizes to support its AdBureau and Engage Knowledge operations. All of Engage's
production data is archived nightly to offline, offsite storage.

   NaviSite's facilities are powered by multiple uninterruptible power supplies
and contain smoke and heat detection, fire suppression, fluid detection and
other disaster protection systems. Engage's data center operations are
controlled using strict password management and physical security measures.

                             Intellectual Property

   We have filed for patents covering our profiling algorithm and our dual-
blind methodology for protecting end-user privacy. The profiling algorithm
patent application covers the process and algorithm for creating user interest
profiles from behavioral data. The dual-blind methodology patent application
covers the process of identifying visitors uniquely at each Web site while
maintaining a central database of cross-referenceable identifiers and allowing
Web sites to access globally-derived data only via their local identifier.
There can be no assurance that any of our patent applications will be granted.
Even if they are granted, these patents may be successfully challenged by
others or invalidated.

   The Engage Knowledge database contains detailed information about millions
of Web users. We believe we have rights to this database's entire data content,
all records and all derived information from the database as a whole, all
updating routines and quality assurance processes and all underlying data
warehousing technology. However, there can be no assurance that any patent,
trade secret or other intellectual property protection will be available for
such information.

   We rely upon a combination of patent, trade secret, copyright and trademark
laws to protect our intellectual property. We also limit access to and
distribution of our proprietary information. However, the steps we take to
protect our intellectual property may not be adequate to deter misappropriation
of our proprietary information. In addition, we may be unable to detect
unauthorized uses of and take appropriate steps to enforce our intellectual
property rights.

   Although we believe that our services and products do not infringe on the
intellectual property rights of others, we are subject to the risk that such a
claim may be asserted against us in the future.

                                  Competition

   The market for Internet marketing solutions, including consumer profiling,
online advertising services and systems, and Web site

                                       49
<PAGE>

traffic analysis is new, rapidly evolving and intensely competitive. Engage
expects competition to increase both from existing competitors and new market
entrants for various components of its services. Engage competes primarily on
the basis of its product features and performance, such as its scalable,
application-independent technology and the anonymity and quality of its global
database of profiles, level of service and, to a lesser extent, on price.

Profiling Solutions

   Engage competes directly with providers of profiling technology, such as
Personify, and indirectly with applications that include more limited profiling
capability integrated into their solution, such as BroadVision and Vignette.
NetGravity, through a partnership with Aptex and MatchLogic, and businesses
that offer cash or other incentives to users to voluntarily provide profile
data have indicated their intent to compete in the global profiling solutions
market. Engage also competes with companies such as DoubleClick and MatchLogic
that have the ability to aggregate large quantities of customer behavior data
across the Web.

Online Advertising Systems and Services

   The primary competitors to Engage's Accipiter AdManager software are
providers of ad serving systems, such as NetGravity and Real Media. In the
outsourced ad serving market, Engage's Accipiter AdBureau service competes with
providers of ad serving services, such as those offered by Adforce and
DoubleClick.

Web Site Traffic Measurement, Auditing and Analysis

   The primary competitors for I/PRO's NetLine Web measurement service and the
Engage DecisionSupportServer product are companies offering outsourced
solutions or software solutions, such as Accrue, Andromedia, net.Genesis and
WebTrends. Nielsen I/PRO I/Audit service competes with auditing services from
ABC Interactive, BPA and PricewaterhouseCoopers.

   Many of Engage's current competitors, as well as a number of potential new
competitors, have longer operating histories, greater name recognition and
substantially greater financial, technical and marketing resources than Engage.
Engage's current and potential competitors also may have more extensive
customer bases and larger proprietary databases. In addition, current and
potential competitors have established or may establish cooperative
relationships among themselves or with third parties to more effectively
distribute their products or to enhance their product and service offerings.

   In addition to these current and potential commercial competitors, Engage
also faces competition from the internal capabilities of some potential
customers. Some of the largest Web publishers use internally developed
interactive marketing solutions rather than the commercial solutions offered by
Engage and its competitors. There can be no assurance that Engage will be able
to compete successfully with these internally developed solutions.

   Increased competition may result in price reductions, reduced gross margins
and loss of market share, any of which could have a material adverse effect on
Engage's business, financial condition and results of operations. There can be
no assurance that Engage will be able to compete successfully against existing
or potential competitors or that competitive pressures will not have a material
adverse effect on Engage's business, financial condition and results of
operations.

                                   Employees

   As of April 30, 1999, Engage had 209 employees and 40 contractors. Employees
included 57 in development, 63 in customer support and operations, 66 in
selling and marketing, and 23 in administration. Of these, 203 employees were
located in the United States and 6 in Europe. Included in the 40 contractors
are 11 offshore contract developers in India.

   Engage believes that its future success is dependent on attracting and
retaining highly skilled engineering, sales and marketing, and

                                       50
<PAGE>

senior management personnel. Competition for such personnel is intense, and
there can be no assurance that Engage will continue to be able to attract and
retain high-caliber employees. Engage believes that the use of offshore
developers gives it access to scarce technical talent at a favorable cost.

   Engage is not subject to any collective bargaining agreements and believes
that its relationship with its employees is good.

                                   Facilities

   Engage's principal executive offices are located in Andover, Massachusetts,
with an engineering center in Raleigh, North Carolina, and offices in Redwood
City and San Francisco, California and a sales office in London. Consisting of
an aggregate of approximately 55,000 square feet, these facilities are
currently leased to the Company under leases which are allocated to Engage from
CMGI on a headcount basis or expire in 1999, 2002 and 2004, respectively.
Engage also leases space for its sales and marketing efforts in New York and
the United Kingdom. Engage believes that suitable additional space to
accommodate the anticipated growth will be available in the future on
commercially reasonable terms.

                               Legal Proceedings

   Engage is not a party to any material legal proceedings.

                       Option Grants In Last Fiscal Year

   The following table sets forth grants of stock options to Mr. Schaut for the
fiscal year ended July 31, 1998. The exercise price per share of each option
was equal to the fair market value of the common stock on the date of grant as
determined by the board of directors. The potential realizable value is
calculated based on the term of the option at its time of grant (five years).
It is calculated assuming that the fair market value of common stock on the
date of grant appreciates at the indicated annual rate compounded annually for
the entire term of the option, and that the option is exercised and sold on the
last day of its term for the appreciated stock price. These numbers are
calculated based on the requirements of the Securities and Exchange Commission
and do not reflect Engage's estimate of future stock price growth. Mr. Jaye
received no options to purchase either Engage common stock or CMGI common stock
in fiscal 1998.

                                  Stock Plans

1995 Equity Incentive Plan

   The 1995 Equity Incentive Plan provides for the issuance of a maximum of
15,000,000 shares of common stock. Under the 1995 Equity Incentive Plan, Engage
is authorized to grant incentive stock options, non-qualified stock options,
stock appreciation rights and restricted stock awards to employees, consultants
and directors. In general, options granted pursuant to the 1995 Equity
Incentive Plan expire within five years after the original grant date. The
board of directors or an appropriate committee of the Board has the right, at
its discretion, to accelerate the vesting of unexercisable options upon a
change of control of Engage. Options are not assignable or transferable except
by will or the laws of descent or distribution. As of April 30, 1999, an
aggregate of 6,467,794 shares of common stock at a weighted average price of
$2.16 per share were outstanding under the 1995 Equity Incentive Plan.

1999 Employee Stock Purchase Plan

   The 1999 Employee Stock Purchase Plan was adopted by our board of directors
in June 1999. The 1999 Employee Stock Purchase Plan provides for the issuance
of a maximum of 750,000 shares of common stock.

   The 1999 Employee Stock Purchase Plan will be administered by the
compensation committee. All employees of Engage whose customary employment is
for more than 20 hours per week and for more than 6 months in any calendar year
are eligible to participate in the 1999 Employee Stock Purchase Plan. Employees
who would own 5% or more of the total combined voting power or value of
Engage's stock immediately after the grant of the option may not participate in
the 1999 Employee Stock Purchase Plan. To participate in the 1999 Employee
Stock Purchase Plan, an employee must authorize us to deduct an amount, not
less than one percent nor more than 10 percent of a participant's total cash
compensation, from his or her pay during three month plan periods. The exercise
price for the option granted in each payment period is 85% of the lesser of the
last reported sale price of the common stock on the first or last business day
of the plan period.

1999 Stock Option Plan for Non-Employee Directors

   The 1999 Stock Option Plan for Non-Employee Directors was adopted by our
board of directors in June 1999. Under the terms of the 1999 Stock Option Plan
for Non-Employee Directors, directors who are not employees of Engage or any
subsidiary of Engage and not affiliates of an institutional investor that owns
shares of Engage's common stock receive nonstatutory options to purchase shares
of Engage's common stock. A total of 250,000 shares of common stock may be
issued upon exercise of options granted under the plan. The board of directors
has discretion to establish the terms of options granted under the plan. All
options must have an exercise price equal to the fair market value of the
common stock on the date of grant.

                     TRANSACTIONS AND RELATIONSHIP BETWEEN
                                ENGAGE AND CMGI
   Engage was incorporated in July 1995 as a wholly owned subsidiary of CMGI.
CMGI currently owns approximately 96% of Engage's common stock, assuming the
conversion of the convertible note and shares of convertible preferred stock
held by CMGI as of April 30, 1999, and will own 82% upon the closing of this
offering.

   CMGI has the power to elect the entire board of directors of Engage and to
approve or disapprove any corporate transactions or other matters submitted to
Engage stockholders for approval, including the approval of mergers or other
significant corporate transactions. CMGI also holds a majority ownership
position in many of Engage's customers and in NaviSite, which provides data
center operations to Engage.

   Upon the completion of this offering, Engage and CMGI will enter into the
agreements described below for the purpose of defining various present and
prospective arrangements and transactions between them. These agreements were
negotiated between a parent and its subsidiary and therefore are not the result
of negotiations between independent parties. Engage and CMGI intend that these
agreements and the transactions provided for in such agreements, taken as a
whole, accommodate their respective interests in a manner that is fair to both
Engage and CMGI. However, because of the complex nature of the various
relationships between Engage, CMGI and various CMGI subsidiaries and
affiliates, there can be no assurance that each of the agreements described
below, or the transactions provided for in the agreements, were effected on
terms at least as favorable to Engage as Engage could have obtained from
unaffiliated third parties.

   Engage, CMGI and their respective subsidiaries may enter into additional or
modified arrangements and transactions in the future. Engage, CMGI or their
respective subsidiaries, as the case may be, will negotiate the terms of such
arrangements and transactions. Engage expects to adopt a policy that all future
arrangements between Engage and CMGI and their respective subsidiaries will be
on terms that Engage believes are no less favorable to Engage than the terms
Engage believes would be available from unaffiliated parties and must be
approved by a majority of Engage's directors who are not employees of CMGI,
even though such directors may be less than a quorum.

   The following is a summary of the material arrangements and transactions
between Engage and CMGI.

                                Debt Conversion

   In July 1998, Engage issued 800,000 shares of its Series A convertible
preferred stock to CMGI in exchange for (i) cancellation of $8.0 million of
intercompany debt and (ii) shares of common stock of Engage previously held by
CMGI. In July 1998, Engage issued 700,000 shares of its Series A convertible
preferred stock to CMGI pursuant to the merger agreement between Engage and
Accipiter. CMGI currently owns 1,500,000 shares of Engage's Series A
convertible preferred stock at an average purchase price of $2.67 per share.
Each share of Series A convertible preferred stock will convert into 20 shares
of common stock upon the consummation of this offering.

   Engage has issued a secured convertible demand note to CMGI in exchange for
the cancellation of all intercompany debt incurred by Engage to CMGI prior to
February 1, 1999. This note provides that CMGI may elect to convert amounts
payable under the note into Series C convertible preferred stock at any time.
The amount of each borrowing represented by the note is convertible into shares
of Series C convertible preferred stock at the fair market value of such shares
as of the end of the fiscal quarter in which the borrowing was made. In April
1999, Engage borrowed $22,086,307 from CMGI in connection with the acquisition
of I/PRO. Such borrowings are convertible into Series C convertible preferred
stock at a common equivalent price of $5.06 per share. Additional intercompany
debt incurred after February 1, 1999 accrues interest at a rate of 7% per year
compounded monthly until the day CMGI elects to convert the debt into shares of
Series C convertible preferred stock.

                                       58
<PAGE>

All notes held by CMGI were converted into Series C convertible preferred stock
in May 1999. Each share of Series C convertible preferred stock will convert
into twenty shares of common stock upon the completion of this offering.

   The following table illustrates the amount of indebtedness of Engage to CMGI
as of April 30, 1999 and the terms on which it has been converted into Series C
convertible preferred stock:

(1) Excludes $481,221 recorded as additional debt to CMGI pursuant to Engage's
    recording the value of the CMGI shares contributed by CMGI for the I/PRO
    acquisition. Under an informal agreement with CMGI, Engage anticipates that
    this amount will be recorded as additional paid in capital upon the
    ultimate conversion of the CMGI debt.
   Engage expects to borrow additional amounts from CMGI to fund its operations
prior to the closing of this offering, and such borrowings and accrued
interest, net of any repayments, will be converted into additional shares of
common stock at the initial public offering price upon the closing of this
offering.

                Facilities and Administrative Support Agreement

   Upon the closing of this offering, CMGI and Engage will enter a facilities
and administrative support agreement under which CMGI will continue to make
available space at its headquarters in Andover, Massachusetts and will provide
various services to Engage, including tax and administrative, computer and
information systems, telecommunications and utilities. Under this agreement,
CMGI has also agreed to make available to Engage at least 28,000 square feet of
space at its headquarters facilities, subject to termination upon at least 12
months' notice by CMGI. The fees payable by Engage for the availability of
space and other services are typically determined through an allocation of
CMGI's costs based upon the proportion of Engage's employee headcount to the
total headcount of CMGI and other CMGI-related companies located in the same
facility or using the same services.

   In fiscal 1998 and the nine months ended April 30, 1999, Engage paid CMGI
$339,000 and $365,000 or services similar to those provided under the
administrative support agreement.

                            Tax Allocation Agreement

   Upon the closing of this offering, Engage will enter into a tax allocation
agreement with CMGI to allocate responsibilities, liabilities and benefits
relating to taxes. Engage will be required to pay its share of income taxes
shown as due on any consolidated, combined, or unitary tax returns filed by
CMGI for tax periods ending on or before or including the date on which date
Engage will no longer be a member of CMGI's group for federal, state, or local
tax purposes, as the case may be. CMGI will indemnify Engage against liability
for all taxes in respect of consolidated, combined, or unitary tax returns for
such periods. Accordingly, any redetermined tax liabilities for such periods
will be the responsibility of CMGI, and any refunds or credits of taxes
attributable to Engage or its subsidiaries in respect of consolidated,
combined, or unitary tax returns for such periods will be for the account of
CMGI. Engage will be responsible for filing any separate tax returns for any
taxable period and will be responsible for any tax liabilities (and entitled to
any refunds or credits of taxes) in respect of such returns. Engage will
indemnify CMGI against liability for such taxes.

                                       59
<PAGE>

   Neither CMGI nor Engage will have any obligation to make any payment to the
other party for the use of such other party's tax attributes such as net
operating losses. However, if one party realizes a windfall tax benefit because
of an adjustment to items on the other party's tax return, the party that
realizes the windfall tax benefit will be required to pay to the other party
the actual incremental tax savings it has realized. For example, if an expense
deducted by CMGI for a period prior to the closing date were disallowed and
required to be capitalized by Engage for a period after the closing date,
thereby generating future depreciation deductions to Engage, Engage would be
required to pay to CMGI any incremental tax savings as a result of such
depreciation deductions when such tax savings are actually realized by Engage.

   Each of Engage and CMGI has control of any audit, appeal, litigation or
settlement of any issue raised with respect to a tax return for which it has
filing responsibility. Payments of claims under the agreement must be made
within 30 days of the date that a written demand for the claim is delivered.
Interest accrues on payments that are not made within 10 days of the final due
date at the rate applicable to under payments of the applicable tax. Any
dispute concerning the calculation or basis of determination of any payment
provided under the tax allocation agreement will be resolved by a law firm or
"big five" accounting firm selected and paid for jointly by the parties.

                           Investor Rights Agreement


   Upon the closing of the offering, Engage and CMGI will enter into an
investor rights agreement under which Engage will grant CMGI registration
rights and rights to purchase shares to maintain its majority ownership. Under
this agreement, CMGI and its assignees will have the right to demand, on up to
seven occasions, that Engage register under the Securities Act the sale of all
or part of their shares of Engage common stock. CMGI and its assignees are also
entitled to include shares of Engage common stock in a registered offering of
securities by Engage for its own account, subject to the underwriters' right to
reduce the number of included shares. Engage will pay all costs associated with
such registration of shares pursuant to this agreement, other than underwriting
discounts and commissions and various other expenses. Also under this
agreement, until such time as CMGI, or any permitted transferee, owns less than
a majority of voting power of the outstanding shares of capital stock of
Engage, Engage will permit CMGI, or the transferee, to purchase a portion in
any shares that it may in the future issue so that CMGI or the transferee may
maintain its majority ownership position. Any such purchases will be at the
same price as is paid by third parties for the shares. This right is
transferable by CMGI to any party that acquires directly from CMGI shares of
common stock representing at least a majority of the outstanding shares of
common stock of Engage.

                    Other Transactions with CMGI Affiliates

   Engage outsources its data center operations for Engage Knowledge and its
AdBureau advertising management service to NaviSite, a CMGI affiliate. For
Engage Knowledge, Engage leases computer equipment and space for equipment from
NaviSite. Engage pays NaviSite fees based on the amount of space and amount of
telecommunications services used by NaviSite to support Engage Knowledge. For
AdBureau, NaviSite provides comprehensive operational and facilities support.
Engage pays NaviSite a percentage of AdBureau revenue. Engage also leases
office computer equipment from NaviSite. Engage expects to continue to
outsource its data center operations to NaviSite and to lease computer
equipment and space for such equipment from NaviSite. Engage paid a total of
$1.2 million, $889,000 and $1.6 million to NaviSite for these services in
fiscal 1997, fiscal 1998 and the nine months ended April 30, 1999.

   Engage sells its products and services to customers affiliated with CMGI. In
fiscal 1998 and the nine months ended April 30, 1999, revenue of Engage from
sales to these affiliated companies totalled $235,000 and $1.4 million.

                         DESCRIPTION OF CAPITAL STOCK
   Effective upon the closing of this offering and the filing of Engage's
amended and restated certificate of incorporation, the authorized capital
stock of Engage will consist of 150,000,000 shares of common stock, par value
$.01 per share, and 5,000,000 shares of preferred stock, par value $.01 per
share.

   The following summary description of Engage's capital stock, as of the
closing of this offering, is not intended to be complete and is qualified by
reference to the provisions of applicable law and to Engage's amended and
restated certificate of incorporation and amended and restated by-laws filed
as exhibits to the registration statement of which this prospectus is a part.

                                 Common Stock

   As of April 30, 1999, there were 39,973,798 shares of common stock
outstanding and held of record by 82 stockholders, after giving effect to the
conversion of all convertible demand notes held by CMGI into convertible
preferred stock and outstanding shares of convertible preferred stock into
common stock upon the closing of this offering. Based upon the number of
shares outstanding as of April 30, 1999 and giving effect to the issuance of
the shares of common stock offered by Engage hereby and the sale of 938,000
shares of common stock to be issued prior to the closing of this offering,
there will be 46,911,798 shares of common stock outstanding upon the closing
of this offering. In addition, as of April 30, 1999, there were outstanding
stock options for the purchase of a total of 6,467,794 shares of common stock.

   Holders of common stock are entitled to one vote per share for each share
held of record on all matters submitted to a vote of stockholders and do not
have cumulative voting rights. Directors are elected by a plurality of the
votes of the shares present in person or by proxy at the meeting. The holders
of common stock are entitled to receive ratably such lawful dividends as may
be declared by the board of directors. However, such dividends are subject to
preferences that may be applicable to the holders of any outstanding shares of
preferred stock. In the event of a liquidation, dissolution or winding up of
the affairs of Engage, whether voluntarily or involuntarily, the holders of
common stock will be entitled to receive pro rata all of the remaining assets
of Engage available for distribution to its stockholders. Any such pro rata
distribution would be subject to the rights of the holders of any outstanding
shares of preferred stock. The common stock has no preemptive, redemption,
conversion or subscription rights. All outstanding shares of common stock are
fully paid and non-assessable. The shares of common stock to be issued by
Engage in this offering will be fully paid and non-assessable. The rights,
powers, preferences and privileges of holders of common stock are subject to,
and may be adversely affected by, the rights of the holders of shares of any
series of preferred stock that Engage may designate and issue in the future.
Upon the closing of this offering, there will be no shares of preferred stock
outstanding.

                                Preferred Stock

   The board of directors will be authorized, subject to any limitations
prescribed by Delaware law, without further stockholder approval, to issue
from time to time up to an aggregate of 5,000,000 shares of preferred stock,
in one or more series. The board of directors is also authorized, subject to
the limitations prescribed by Delaware law, to establish the number of shares
to be included in each series and to fix the voting powers, preferences,
qualifications and special or relative rights or privileges of each series.
The board of directors is authorized to issue preferred stock with voting,
conversion and other rights and preferences that could adversely affect the
voting power or other rights of the holders of common stock.

   Engage has no current plans to issue any preferred stock. However, the
issuance of preferred stock or of rights to purchase preferred stock could
have the effect of making it more difficult for a third party to acquire, or
of discouraging a third party from attemping to acquire, a majority of the
outstanding common stock of Engage.

                              Registration Rights

   The Series B Convertible Preferred Stock Purchase Agreement dated as of
July 31, 1998
                                      63
<PAGE>

provides that the holders of 238,597 shares are entitled to rights with respect
to the registration of such shares under the Securities Act. If Engage proposes
to register any of its securities under the Securities Act, either for its own
account or for the account of another securityholder, the holders are entitled
to notice of such registration and to include their registrable shares in such
registration. However, in the event of a registration pursuant to an
underwritten public offering of common stock, the underwriters shall have the
right to limit the number of shares included in such registration. These rights
terminate for a holder at such time as such holder could sell all of its shares
under Rule 144(k) under the Securities Act. See "Transactions and Relationship
Between Engage and CMGI -- Investor Rights Agreement" for information
concerning registration rights granted to CMGI.

                Section 203 of Delaware General Corporation Law

   The certificate of incorporation of Engage contains a provision expressly
electing not to be governed by Section 203 of the Delaware General Corporation
Law. In general, Section 203 restricts some business combinations involving
interested stockholders, defined as any person or entity that is the beneficial
owner of at least 15% of a corporation's voting stock or is an affiliate or
associate of the corporation or the owner of 15% or more of the outstanding
voting stock of the corporation at any time in the past three years, or their
affiliates. Because of such election, Section 203 will not apply to Engage.

                  Limitation of Liability and Indemnification

   The certificate of incorporation provides that no director of Engage shall
be personally liable to Engage or to its stockholders for monetary damages for
breach of fiduciary duty as a director, except that the limitation shall not
eliminate or limit liability to the extent that the elimination or limitation
of such liability is not permitted by the Delaware General Corporation Law as
it exists or may later be amended.

   The certificate of incorporation further provides for the indemnification of
Engage's directors and officers to the fullest extent permitted by Section 145
of the Delaware General Corporation Law, including circumstances in which
indemnification is otherwise discretionary. In addition, Engage plans to enter
into indemnification agreements with its directors containing provisions which
may require Engage, among other things, to indemnify its directors against
various liabilities that may arise by virtue of their status or service as
directors, and to advance their expenses incurred as a result of any proceeding
against them as to which they could be indemnified.

                              Stock Transfer Agent

                        SHARES ELIGIBLE FOR FUTURE SALE

   Sales of substantial amounts of our common stock in the public market could
adversely affect prevailing market prices of our common stock. Furthermore,
since some shares of common stock will not be available for sale shortly after
this offering because of the contractual and legal restrictions on resale
described below, sales of substantial amounts of common stock in the public
market after these restrictions lapse could adversely affect the prevailing
market price and our ability to raise equity capital in the future.

   Upon completion of this offering, we will have outstanding an aggregate of
46,911,798 shares of our common stock assuming no exercise of outstanding
options. Of these shares, all of the shares sold in this offering will be
freely tradable without restriction or further registration under the
Securities Act, unless such shares are purchased by "affiliates" as that term
is defined in Rule 144 under the Securities Act. Of the remaining 40,911,798
shares, all shares 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 Rule 144 or 701 under the Securities Act, which rules are summarized
below.

                               Lock-Up Agreements

   Stockholders holding an aggregate of 39,901,614 shares of common stock,
including all of our officers and directors who hold shares of common stock or
options to purchase shares of common stock, have signed lock-up agreements with
the underwriters under which they agreed 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 Goldman, Sachs & Co.;

  . in the case of transfers to affiliates;

  . as a bona fide gift; or

  . to any trust.

   Upon expiration of the lock-up period, 180 days after the date of this
prospectus,     shares will be available for resale to the public in accordance
with Rule 144.

   In addition, stockholders holding an aggregate of 1,010,184 shares have
signed lock-up agreements with CMGI under which they agreed 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 until April 7, 2000. CMGI has agreed not to waive these restrictions for
a period of 180 days after the date of this prospectus, without the consent of
Goldman Sachs & Co.

                                    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 would be entitled to sell within any three-
month period a number of shares that does not exceed the greater of:

  . 1% of the number of shares of common stock then outstanding, which will
    equal approximately 469,000 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 preceding the filing of a
    notice on Form 144 with respect to such sale.

   Sales under Rule 144 are also subject to 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 is not one of our affiliates at any time
during the three months preceding a sale, and who has beneficially owned the
shares proposed to be sold for at least two years, including the holding period
of any prior owner other than an affiliate, is entitled to sell such shares
without complying with the manner of sale, public information, volume
limitation or notice provisions of

                                       65
<PAGE>

Rule 144. Therefore, unless otherwise restricted, "144(k) shares" may be sold
immediately upon the completion of this offering.

                                    Rule 701

   In general, under Rule 701 of the Securities Act as currently in effect, any
of our employees, consultants or advisors who purchases shares from us in
connection with a compensatory stock plan or other written agreement is
eligible to resell such shares 90 days after the effective date of this
offering in reliance on Rule 144, but without compliance with various
restrictions, including the holding period, contained in Rule 144.

                              Registration Rights

   Upon completion of this offering, the holders of 38,748,474 shares of our
common stock or their transferees, including CMGI, will be entitled to various
rights with respect to the registration of such shares under the Securities
Act. See "Description of Capital Stock --Registration Rights" and "Transactions
and Relationship Between Engage and CMGI --Investor Rights Agreement".

                          Independent Auditors' Report

The Board of Directors
Engage Technologies, Inc.:

We have audited the accompanying consolidated balance sheets of Engage
Technologies, Inc. and subsidiaries as of July 31, 1997 and 1998, and April 30,
1999, and the related consolidated statements of operations, changes in
stockholders' equity (deficit), and cash flows for each of the years in the
three-year period ended July 31, 1998 and the nine months ended April 30, 1999.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these consolidated 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 consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Engage
Technologies, Inc. and subsidiaries as of July 31, 1997 and 1998 and April 30,
1999, and the results of their operations and their cash flows for each of the
years in the three-year period ended July 31, 1998 and the nine months ended
April 30, 1999, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

           All information included in these footnotes as of and for
               the nine months ended April 30, 1998 is unaudited

(1) Description of Business

   Engage provides products and services that enable customers to create and
use profiles of individual Web visitors to target advertisements, content and
e-commerce offerings.

(2) Summary of Significant Accounting Policies

 Basis of Presentation

   The Company is a majority owned subsidiary of CMGI, Inc. ("CMGI"). The
accompanying consolidated financial statements, which have been prepared as if
the Company had operated as a separate stand-alone entity for all periods
presented, include only revenue and expenses attributable to the Company since
it commenced operations in September 1995.

   The consolidated financial statements include certain allocations based on
headcount from CMGI for certain general and administrative expenses such as
rent, legal services, insurance and employee benefits. Management believes that
the method used to allocate the costs and expenses is reasonable; however, such
allocated amounts may or may not necessarily be indicative of what actual
expenses would have been incurred had the Company operated independently of
CMGI.

 Principles of Consolidation

   The accompanying financial statements include the accounts of the Company
and its wholly-owned subsidiaries, Internet Profiles Corporations ("I/PRO") and
Engage Technologies Limited, after elimination of all significant intercompany
balances and transactions.

 Use of Estimates

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

 Revenue Recognition

   Prior to August 1, 1998, revenue from sales of product licenses to customers
were generally recognized when the product was shipped, provided no significant
obligations remain and collectibility is probable, in accordance with Statement
of Position ("SOP") 91-1, Software Revenue Recognition. Effective August 1,
1998, the Company adopted the provisions of SOP 97-2, Software Revenue
Recognition. For transactions after August 1, 1998, revenues from software
product licenses and web-site traffic audit reports are generally recognized
when (i) a signed noncancelable software license exists, (ii) delivery has
occurred, (iii) the Company's fee is fixed or determinable, and (iv)
collectibility is probable. Revenue from license agreements that have
significant customizations and modifications of the software product is
deferred and recognized using the percentage of completion method. There was no
material change to the Company's accounting for revenue as a result of the
adoption of SOP 97-2.

                           ENGAGE TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   Revenue from periodic subscriptions is recognized ratably over the
subscription term, typically twelve months. Revenue from usage based
subscriptions is recognized monthly based on actual usage.

   Service and support revenue includes software maintenance and other
professional services revenues, primarily from consulting, implementation and
training. Revenue from software maintenance is deferred and recognized ratably
over the term of each maintenance agreement, typically twelve months. Revenue
from professional services is recognized as the services are performed,
collectibility is probable and such revenues are contractually non-refundable.

   Amounts collected prior to satisfying the above revenue recognition criteria
are classified as deferred revenue.

 Cash

   Under an arrangement with CMGI, the Company maintains a zero balance cash
account. Cash required by the Company for the funding of its operations is
provided as needed with a corresponding increase in the "Debt to CMGI" account.
Customer receipts and other cash receipts of the Company are remitted to CMGI
upon receipt by the Company and serve to reduce the "Debt to CMGI" account.
Cash on hand at July 31, 1998 and April 30, 1999 is held by the Company's
subsidiaries.

   During fiscal 1998, non-cash investing activities included the sale of data
warehouse product rights in exchange for available-for-sale securities and the
repayment of approximately $8,400,000 of debt due to CMGI. In addition, non-
cash investing activities also include the Company's acquisition of Accipiter
(see note 7) in exchange for 700,000 shares of the Company's Series A
Convertible Preferred Stock.

   During fiscal 1998, non-cash financing activities included the issuance of
800,000 shares of the Company's Series A Convertible Preferred Stock in
exchange for 16,000,000 shares of the Company's common stock and an $8,000,000
reduction in the debt to CMGI (see note 10).

   During fiscal 1999, non-cash investing activities include the acquisition of
I/PRO (see note 7) in exchange for 1,010,184 shares of the Company's common
stock, and additional debt to CMGI totaling $22,086,000.

 Marketable Securities

   The appropriate classification of marketable securities is determined at the
time of acquisition and reevaluated at each balance sheet date. Marketable
securities have been classified as available-for-sale and are carried at fair
value, based on quoted market prices, with unrealized gains and losses included
in accumulated other comprehensive income (loss) on the consolidated balance
sheets.

 Property and Equipment

   Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets.
Leasehold improvements and assets under capital leases are amortized using the
straight-line method over the shorter of the lease term or estimated useful
life of the asset. Expenditures for maintenance and repairs are charged to
expense as incurred.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


 Investment in Joint Venture

   The Company's investment in the common stock of a Japanese joint venture is
accounted for by the equity method.

 Intangibles

   Intangibles relate to the Company's purchase of Accipiter, Inc. in April
1998 and I/PRO in April 1999 (see note 7). Such costs are being amortized on a
straight-line basis over either two or five years, depending on the periods
expected to be benefited.

 Accounting for Impairment of Long-Lived Assets

   The Company assesses the need to record impairment losses on long-lived
assets used in operations when indicators of impairment are present. On an on-
going basis, management reviews the value and period of amortization or
depreciation of long-lived assets, including costs in excess of net assets of
companies acquired. During this review, the significant assumptions used in
determining the original cost of long-lived assets are reevaluated. Although
the assumptions may vary from transaction to transaction, they generally
include revenue growth, operating results, cash flows and other indicators of
value. Management then determines whether there has been a permanent impairment
of the value of long-lived assets by comparing future estimated undiscounted
cash flows to the asset's carrying value. If the estimated future undiscounted
cash flows exceed the carrying value of the asset, a loss is recorded as the
excess of the asset's carrying value over fair value.

 Research and Development Costs and Software Costs

   Expenditures related to the development of new products and processes,
including significant improvements and refinements to existing products and the
development of software, are expensed as incurred, unless they are required to
be capitalized. Software development costs are required to be capitalized when
a product's technological feasibility has been established by completion of a
detailed program design or working model of the product, and ending when a
product is available for general release to customers. To date, the
establishment of technological feasibility and general release have
substantially coincided. As a result, there have been no capitalized software
development costs to date. Additionally, at the date of acquisition or
investment, the components of the purchase price of each acquisition or
investment are evaluated to identify amounts allocated to in-process research
and development. Upon completion of acquisition accounting and valuation, such
amounts are charged to expense if technological feasibility had not been
reached at the acquisition date.

 Foreign Currency Translation

   The functional currency for the Company's foreign subsidiary and its
investment in joint venture is its local currency. The financial statements of
this subsidiary and the joint venture are translated into United States dollars
using period-end exchange rates for assets and liabilities and average exchange
rates during the period for revenues and expenses. The resulting translation
adjustments are included in accumulated other comprehensive income (loss) on
the consolidated balance sheets. Net gains and losses resulting from foreign
currency transactions arising from exchange rate fluctuations on transactions
denominated in currencies other than the functional currencies are included in
the consolidated statements of operations and were immaterial for all periods
presented.

 Income Taxes

   The Company accounts for income taxes under the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. 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. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date. The Company is currently greater than 80% owned by CMGI, and as
such, CMGI realizes the full benefit of all federal and part of the state net
operating losses that have been incurred by the Company. Therefore, such net
operating losses incurred by the Company will have no future benefit to the
Company. The tax sharing agreement between the Company and CMGI requires the
Company to reimburse CMGI to the extent it contributes to the consolidated tax
liability of the CMGI group; however, under the policy, CMGI is not obligated
to reimburse the Company for any losses utilized in the consolidated CMGI
group.

 Advertising Costs

   The Company expenses advertising costs as incurred. The Company did not
incur any advertising costs during the year ended July 31, 1996. Advertising
expense was approximately $40,000, $175,000 and $564,000 for the fiscal years
ended July 31, 1997 and 1998 and the nine months ended April 30, 1999,
respectively.

 Stock-Based Compensation Plans

   The Company has adopted SFAS No. 123, Accounting for Stock-Based
Compensation ("SFAS 123"). As permitted by SFAS 123, the Company measures
compensation cost in accordance with Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees ("APB No. 25"), and related
interpretations. Accordingly, no accounting recognition is given to stock
options granted at fair market value until they are exercised. Upon exercise,
net proceeds, including income tax benefits realized, are credited to equity.
Compensation cost for stock options granted with exercise prices below
estimated fair market value is recognized over the vesting period, typically
four years. The adoption of SFAS 123 was not material to the Company's
financial condition or results of operations; however, the pro forma impact on
earnings has been disclosed in the notes to the consolidated financial
statements as required by SFAS 123 (see note 11).

 Segment Reporting

   The Company has adopted SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information" ("SFAS 131"). SFAS 131 establishes
standards for the way that public business enterprises report selected
information about operating segments in annual and interim financial
statements. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. SFAS 131 requires
the use of the "management approach" in disclosing segment information, based
largely on how senior management generally analyzes the business operations.
SFAS 131 has been adopted effective August 1, 1998. The Company currently
operates in only one segment, and as such, no additional disclosures are
required.

 Unaudited Pro Forma Basic and Diluted Net Loss per Share

   Unaudited pro forma basic earnings (loss) per share is based upon the
weighted average number of common shares outstanding during the period.
Unaudited pro forma diluted earnings (loss) per share is based upon the
weighted average number of common shares outstanding during the period plus
additional weighted average common equivalent shares outstanding during the
period, computed using the "if-converted method". Common equivalent shares have
been excluded from the computation of diluted loss per share in each period, as
their effect would have been anti-dilutive in each period presented.

   As described in note 16, conversion of all preferred stock and debt to CMGI
will occur upon the completion of a qualified public offering of the Company's
common stock. The unaudited pro forma basic and diluted net loss per share
information included in the accompanying statements of operations for the year
ended July 31, 1998 and the nine months ended April 30, 1999 reflects the
impact on unaudited pro forma basic and diluted net loss per share of such
conversion as of the beginning of each period or date of issuance, if later,
using the if-converted method.

   Historical basic and diluted net loss per share have not been presented
because they are irrelevant due to the significant change in the Company's
capital structure and resultant basic and diluted loss per share that will
result upon conversion of the convertible preferred stock and debt to CMGI.

   The reconciliation of the numerators and denominators of the unaudited pro
forma basic and unaudited pro forma diluted loss per share computation for the
Company's reported net loss is as follows:

 New Accounting Pronouncements

   In March 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants ("AcSEC"), issued Statement of
Position 98-1, "Accounting for the Cost of Computer Software Developed or
Obtained for Internal Use" ("SOP 98-1"). SOP 98-1 requires the

                                      F-11

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

capitalization of certain internal costs related to the implementation of
computer software obtained for internal use. The Company is required to adopt
this standard in the first quarter of fiscal 2000, and expects that the
adoption of SOP 98-1 will not have a material impact on its financial position
or its results of operations.

   In April 1998, the AcSEC issued Statement of Position 98-5, "Reporting Costs
of Start-Up Activities" ("SOP 98-5"). Under SOP 98-5, the cost of start-up
activities should be expensed as incurred. Start-up activities are broadly
defined as those one-time activities related to opening a new facility,
introducing a new product or service, conducting business in a new territory,
conducting business with a new class of customer, commencing some new operation
or organizing a new entity. SOP 98-5 is effective for the Company's fiscal 2000
financial statements. The Company does not expect its adoption to have a
material impact on its financial position or results of operations.

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133").
SFAS 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts (collectively referred to as derivatives) and for hedging activities.
SFAS 133 requires the recognition of all derivatives as either assets or
liabilities in the statement of financial position and the measurement of those
instruments at fair value. The Company is required to adopt this standard in
the first quarter of fiscal 2000, and expects that the adoption of SFAS 133
will not have a material impact on the its financial position or its results of
operations. On May 20, 1999, a proposed Statement of Financial Accounting
Standards was issued for public comment in which the proposal, if approved,
will delay implementation until the first quarter of the Company's fiscal year
2000.

 Unaudited Interim Financial Information

   The consolidated financial statements for the nine months ended April 30,
1998 are unaudited; however, in the opinion of management, all adjustments
(consisting of normal recurring adjustments) necessary for a fair presentation
of the financial statements for the interim period have been included. Results
of operations for the interim periods presented are not necessarily indicative
of the results that may be expected for the full fiscal year or any other
future period.

(3) Sale of Product Rights

   In August 1997, the Company sold rights to some of its data warehouse
software products to Red Brick Systems, Inc. ("Red Brick") for $9,500,000 in
cash and 238,160 shares of Red Brick common stock, recording a pretax gain of
$9,240,000 on the sale. The cash component was received directly by CMGI and
Debt to CMGI was reduced by a corresponding amount. In January 1999, the Red
Brick shares were exchanged for 142,896 shares of Informix Corp. due to
Informix's acquisition of Red Brick.

(4) Available-for-Sale Securities

   Available-for-sale securities at July 31, 1998 consists of 238,160 shares of
Red Brick common stock received as part of the Company's sale of product rights
to Red Brick. Available-for-sale securities at April 30, 1999 consists of
142,896 shares of Informix Corp. (see note 3). These securities are carried at
fair value based on quoted market prices. A $1,193,000 and $724,000 unrealized
holding loss was recorded on the Red Brick shares at July 31, 1998 and April
30, 1999, respectively, based on the change in market value since the date of
acquisition. The unrealized holding loss is presented in the equity section of
the Company's consolidated balance sheet as a component of accumulated other
comprehensive loss.

The Company had no assets under capital lease at July 31, 1997 or 1998.

(6) Investment in Joint Venture

   In August 1998, the Company acquired for $1.4 million in cash, 49% of the
shares of Engage Technologies Japan (the "Joint Venture"), a joint venture with
Sumitomo Corporation in Japan. The Company's ownership interest was reduced to
46.3% in March 1999 as a result of the Joint Venture's selling an ownership
interest to an additional investor. The Joint Venture was established to sell
the Company's products and services in Japan. The Joint Venture is authorized
to solicit additional investors so long as the new investors' ownership
interests do not exceed 30% on a fully diluted, aggregate ownership basis. If
the Joint Venture requires funds in excess of $4 million (excluding the
parties' initial capital contributions) for its operations, the Company is
required to provide a bank guarantee in an amount proportionate to its
ownership interest. This investment is being accounted for under the equity
method of accounting. The Company's share of the Joint Venture's foreign
currency translation adjustments is reflected in both the investment account
and shareholders' equity on the consolidated balance sheet as a component of
accumulated other comprehensive income (loss).

   Under a separate license agreement, the Company licensed its Engage
Knowledge technology to the Joint Venture in consideration for a non-refundable
$3 million prepaid royalty and royalties of 11.11% of all future revenues. The
initial prepaid royalty has been recorded as deferred revenue and is being
recognized as income over three years, the estimated period over which the
Company expects to provide maintenance and support. In addition, the Company
and the Joint Venture entered into a reseller agreement under which the Company
granted the Joint Venture an exclusive right to resell its products to end
users in Japan, excluding certain Japanese distribution rights granted to Red
Brick (see Note 3).

(7) Acquisitions

 Accipiter

   In April 1998, CMGI acquired Accipiter, Inc. ("Accipiter"), a company
specializing in Internet advertising management solutions, in exchange for
10,109,536 shares of CMGI Common Stock

                                      F-13
<PAGE>

                           ENGAGE TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

(which number reflects three CMGI two-for-one stock splits between April 1998
and the date of these financial statements). In August 1998, Accipiter was
legally merged with the Company in a stock-for-stock merger in which
consideration of 700,000 shares of the Company's Series A Convertible Preferred
Stock was issued to CMGI. The Company has reflected in its consolidated
financial statements and the acquisition of Accipiter as if they occurred in
April 1998. The total purchase price for Accipiter was valued at $31,253,000,
including acquisition costs of $198,000. The value of the CMGI shares included
in the purchase price was recorded net of a weighted average 10% market value
discount to reflect the restrictions on transferability.

   Management is primarily responsible for estimating the fair value of
purchased in-process research and development. The portion of the purchase
price allocated to in-process research and development was $9,200,000, or
approximately 29% of the total purchase price. At the acquisition date,
Accipiter's major in-process project was the development of AdManager version
4.0, which was intended to provide the ad serving functionality that customers
were requiring as the use of the Internet rapidly increased and customer Web
sites became more complex. In general, previous AdManager releases did not
provide for the fault tolerance, redundancy and scalability that customers
began to seek after AdManager versions 1.0 and 2.0 were released. Accordingly,
customers' long-term product needs required Accipiter to substantially redesign
the AdManager architecture (later released as version 4.0) to develop new
technologies in the areas of: (1) fault tolerance and scalability, (2) an
object-oriented user interface, (3) application programming interfaces and (4)
a new report engine.

   At the date of the acquisition, management estimated that completion of the
AdManager version 4.0 technology would be accomplished by June 1998. Engage
began testing AdManager version 4.0 at a customer's site (beta testing) in June
1998 and commercially released the product in August 1998. The initial
development effort had commenced in late 1997. At the acquisition date, the new
AdManager technology had not reached a completed prototype stage and beta
testing had not yet commenced. At the time of the Accipiter purchase, the
AdManager version 4.0 project was approximately 71% complete.

   The value of in-process research and development was determined using an
income approach. This approach takes into consideration earnings remaining
after deducting from cash flows related to the in-process technology, the
market rates of return on contributory assets, including developed technology,
assembled workforce, working capital and fixed assets. The cash flows are then
discounted to present value at an appropriate rate. Discount rates are
determined by an analysis of the risks associated with each of the identified
intangible assets. The discount rate used for in-process research and
development was 24.5%, a slight premium over the estimated weighted-average
cost of capital of 24%, and the discount rate used for developed technology was
21%.

   The resulting net cash flows to which the discount rate was applied are
based on Engage management's estimates of revenues, cost of revenues, research
and development costs, selling and marketing costs, general and administrative
costs, and income taxes from such acquired technology. These estimates are
based on the assumptions set forth below.

   Accipiter recorded revenue in 1997 of less than $1 million. Because of the
absence of meaningful historical revenue of Accipiter, management projected
revenue for the initial year of the forecast period based on its assessment of
future market potential and the ability of Accipiter to successfully launch its
new product offering. After the initial year of the forecast period, revenue
was predicted to grow at rates comparable to the growth of Internet users and
online activity and the impact such growth would have on Internet advertising.

                           ENGAGE TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   These projections are based on Engage management's estimates of the
significant growth in the number of companies engaged in e-commerce (which is
supported by independent market data), the need for e-commerce companies to
serve ads over the Internet, expected trends in technology (such as increased
speed of the Internet, reduced hardware costs and the resulting increase in new
Internet users to whom ads will be served) and the nature and expected timing
of new product introductions by Engage and its competitors. These estimates
also include growth related to the use of certain Accipiter technologies in
conjunction with Engage's products, the marketing and distribution of the
resulting products through Engage's sales force and the benefits of Engage's
incremental financial support and stability.

   Engage's estimated cost of sales as a percentage of revenue is expected to
be slightly lower than Accipiter's (classified as support and royalties by
Accipiter) on a stand-alone basis (16% in 1997), as certain fixed costs
included in cost of sales are spread over a larger revenue base and provide for
the realization of efficiencies due to economies of scale through combined
operations. Due to these savings, the estimated cost of sales as a percentage
of revenue is expected to decrease by 1% each year from Accipiter's historical
percentage, to a low of 11% in the fifth forecast year.

   Engage's selling, general and administrative costs are expected to be higher
than Accipiter's on an absolute basis, but lower as a percentage of revenue.
Due to the small revenue base in 1997 and the impact of significant costs
associated with building a corporate infrastructure and building a workforce
for future operations, Accipiter's selling, general and administrative costs in
1997, as a percent of revenue, are not representative of the expected costs for
the combined operations of Engage and Accipiter. Efficiencies due to economies
of scale through combined operations, such as consolidated marketing and
advertising programs, are expected to be realized immediately.

   Approximately $1,700,000 of deferred compensation was recorded during fiscal
1998 relating to approximately 173,080 shares of CMGI common stock issued to
the then employee stockholders of Accipiter, which are being held in escrow.
These shares are subject to forfeiture upon termination of employment over a
two-year period. Compensation expense is being recognized over the two-year
service period beginning August 1, 1998.

 I/PRO

   In April 1999, Engage acquired I/PRO, a provider of Web-site traffic
measurement and audit services, for approximately $32,651,000, including
acquisition costs of $244,000. The purchase price consisted of $1,563,000 in
net cash, $20,907,000 in CMGI common shares and $10,181,000 in Engage common
shares and options. The per share value of the CMGI shares included in the
purchase price was $57.99, net of a 9% weighted average market value discount
to reflect the restriction on transferability. The per share value of the
Engage shares included in the purchase price was $6.58 per share. In addition,
CMGI must pay up to $3,000,000 to the former I/PRO stockholders if stated
performance goals are met by I/PRO one year after the closing. Engage must
reimburse CMGI for any payments, due under stated performance goals, in cash or
by issuance of shares of Engage's Series C convertible preferred stock at its
then fair market value, at CMGI's election. Any additional payments will be
treated as additional purchase price.

   I/PRO's major in-process project was the development of a new data
processing system, project name Normandy, which is intended to provide the
improved functionality required as the use of the Internet rapidly increases
and customer Web site activity increases in volume and complexity. In general,
the existing data processing system does not provide sufficient fault
tolerance, scalability, and data processing efficiency that will be required to
meet future customer needs. Accordingly, customer's long-term product needs
required I/PRO to substantially redesign the data processing system to develop
new technologies in the areas of: (1) fault tolerance and scalability, (2)
system management, (3) data capture and (4) path analysis functionality.

   At the date of the acquisition, management estimated that completion of the
Normandy technology would be accomplished by August, 1999. The initial
development effort had commenced in late 1998. At the acquisition date, the new
Normandy technology had not reached a completed prototype stage and beta
testing had not yet commenced. At the time of the I/PRO purchase, the Normandy
project was approximately 64% complete.

   The value of in-process research and development was determined using an
income approach. This approach takes into consideration earnings remaining
after deducting from cash flows related to the in-process technology, the
market rates of returns on contributory assets, including core developed
technology, assembled workforce, working capital and fixed assets. The cash
flows are then discounted to present value at an appropriate rate. Discount
rates are determined by an analysis of the risks associated with each of the
identified intangible assets. The discount rate used for in-process research
and development was 30%, a premium over the estimated weighted-average cost of
capital of 25%, and the discount rate used for core developed technology was
22%.

   The resulting net cash flows to which the discount rate was applied are
based on Engage management's estimates of revenues, cost of revenues, research
and development costs, selling and marketing costs, general and administrative
costs, and income taxes from such acquired technology. These estimates are
based on the assumptions set forth below.

   Management projected average annual revenues increases for the forecast
period based on its assessment of future market potential and the ability of
I/PRO to successfully implement the Normandy technology. Revenue was predicted
to grow at rates comparable to the growth of Internet users and online activity
and the impact such growth would have on Internet service companies. Revenues
related to the Normandy project were identified.

   These projections are based on Engage management's estimates of the
significant growth in the number of companies engaged in e-commerce, the need
for e-commerce companies to utilize independent audit, verification and
analysis services, expected trends in technology (such as increased speed of
the Internet, reduced hardware costs and the resulting increase in new Internet
users) and the nature and expected timing of new product introductions by
Engage and its competitors. These estimates also include growth related to the
use of certain I/PRO technologies in conjunction with Engage's products and the
benefits of Engage's incremental financial support and stability.

   I/PRO's estimated cost of sales as a percentage of revenue is expected to
significantly decrease on a stand-alone basis (85% in 1998), as certain fixed
costs included in cost of sales are spread over a larger revenue base and
provide for the realization of efficiencies due to economies of scale. Normandy
technology is expected to greatly increase the automation of data processing
allowing significant labor cost savings per revenue dollar. Increases in
hardware utilization are also expected.

expected to decrease to a low of 20% in the fifth forecast year.

   The acquisitions of Accipiter and I/PRO have been accounted for using the
purchase method, and, accordingly, the purchase prices have been allocated to
the assets purchased and liabilities assumed based upon their fair values at
the dates of acquisition. The amount of the purchase prices allocated to
goodwill and developed technology is being amortized on a straight-line basis
over five years. The amount of the purchase price allocated to other
identifiable intangible assets is being amortized on a straight line basis over
the following periods; Accipiter and I/PRO work force over two years, Accipiter
trade name over two years, and I/PRO tradename over five years. Amortization of
developed technology is charged to cost of product revenue while both goodwill
and other identifiable intangible assets are reflected as separate components
within operating expenses.

   The purchase price of the Accipiter and I/PRO acquisitions was allocated as
follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

   In addition to leasing computer equipment under various capital leases, the
Company has entered into noncancelable operating leases covering certain of its
office facilities and equipment which expire through 2004. In addition, the
Company pays CMGI for office facilities used as the Company's headquarters for
which it is charged based upon an allocation of the total costs for the
facilities at market rates.

   The Company leases certain property and equipment from a subsidiary of CMGI.
Under the arrangement, the related party negotiates the terms and conditions of
the lease and obtains the assets to be leased. The related party bears all
liability for payment, and the Company is not financially obligated under the
leases. The Company is charged the actual lease fees paid by the related party,
plus an additional administrative charge that approximates the fair value of
the services received.

   Total rent expense amounted to $36,000, $305,000, $483,000 and $758,000 for
the years ended July 31, 1996, 1997 and 1998 and the nine months ended April
30, 1999, respectively. Rent expense for office facilities paid to CMGI
amounted to approximately $35,000, $274,000, $258,000 and $214,000 for the
years ended July 31, 1996, 1997 and 1998 and the nine months ended April 30,
1999, respectively. Rent expense for equipment paid to a subsidiary of CMGI
amounted to approximately $1,000, $31,000, $125,000 and $231,000 for the years
ended July 31, 1996, 1997 and 1998 and the nine months ended April 30, 1999,

   (b) Contingencies

   Prior to the effectiveness of the registration statement covering the sale
of Engage common stock being sold in the initial public offering, Hambrecht &
Quist, an underwriter of the offering, provided written materials to
approximately 80 Engage employees that Engage had designated as potential
purchasers of up to 300,000 shares of common stock in the offering through a
directed share program. These materials may constitute a prospectus that does
not meet the requirements of the Securities Act of 1933.

                                      F-18
<PAGE>

                           ENGAGE TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   If the distribution of these materials by Hambrecht & Quist did constitute a
violation of the Securities Act of 1933, the recipients of the materials who
purchased common stock in the offering would have the right, for a period of
one year from the date of their purchase of common stock, to obtain recovery of
the consideration paid in connection with their purchase of common stock or, if
they had already sold the stock, sue Engage for damages resulting from their
purchase of common stock. Hambrecht & Quist has agreed to indemnify both Engage
and the other underwriters for liabilities arising out of the distribution of
these written materials to participants in the directed share program. These
damages could total up to approximately $4.5 million plus interest, based on
the initial public offering price of $15.00 per share, if these investors seek
recovery or damages after an entire loss of their investment. While the
ultimate outcome of these matters cannot be determined, Engage does not expect
that they will have a material adverse effect on its consolidated financial
position, results of operations or cash flows.

(9) Income Taxes

   No provision for federal or state income taxes has been recorded as the
Company incurred net operating losses for all periods presented. At April 30,
1999, the Company had no significant net operating loss carryforwards available
to offset future federal taxable income as the Company's parent, CMGI, has
utilized substantially all of the Company's net operating losses through April
30, 1999. The Company has recorded a full valuation allowance against its
deferred tax assets since management believes that, after considering all the
available objective evidence, both positive and negative, historical and
prospective, with greater weight given to historical evidence, it is not more
likely than not that these assets will be realized. No income tax benefit has
been recorded for all periods presented because of the valuation allowance.

   Temporary differences between the financial statement carrying amounts and
tax bases of assets and liabilities that give rise to significant portions of
federal deferred tax assets (liabilities) are comprised of the following:

(10) Stockholders' Equity

   In July 1998, the Company's shareholders authorized 5,000,000 shares of
preferred stock, of which 1,500,000 have been designated as Series A
convertible preferred stock ("Series A Preferred Stock") and 238,597 shares
have been designated as Series B convertible preferred stock ("Series B
Preferred Stock"). In May 1999, the Board of Directors approved the designation
of 2,000,000 shares of the Company's preferred stock as Series C Convertible
Preferred Stock ("Series C Preferred Stock").

 Series A Preferred Stock

   In July 1998, the Board of Directors authorized and issued 800,000 shares of
Series A Preferred Stock in exchange for 16,000,000 shares of the Company's
common stock and $8,000,000 in principal amount of debt to CMGI. The Series A
Preferred Stock is entitled to receive annual dividends at 7%, as and if
declared. As of and prior to July 31, 1998, no dividends had been declared or
paid by the Company. Each share of Series A Convertible Preferred Stock votes
on an as-converted basis and is convertible into twenty shares of common stock
under certain conditions and subject to certain adjustments. In the event of
any liquidation, dissolution or winding up of the Company, the Series A
Preferred Stock has a liquidation preference of $5 per share, plus cumulative
dividends of 7% compounded annually beginning on February 1, 1998. The Series A
Preferred Stock is convertible into common stock immediately at the option of
the holder, and automatically converts into common stock upon the completion of
a qualifying initial public offering, as defined. See note 16.

   In July 1998, the Board of Directors authorized the issuance of an
additional 700,000 shares of Series A Preferred Stock to CMGI in connection
with the Company's acquisition of Accipiter, Inc.

 Series B Preferred Stock

   In August 1998, the Board of Directors designated and issued 238,597 shares
of Series B Preferred Stock. Proceeds from the sale were $1,934,000, net of
issuance costs of $6,000. Each share of Series B Preferred Stock votes on an
as-converted basis and is convertible into two shares of common stock under
certain conditions and subject to certain adjustments. In the event of any
liquidation, dissolution or winding up of the Company, the Series B Preferred
Stock has a liquidation preference of $8.38 per share, subject to the prior
payment of the liquidation preference on Series A Preferred Stock. The Series B
Preferred Stock is convertible into common stock immediately at the option of
the holder, and automatically converts into common stock upon the completion of
a qualifying initial public offering, as defined in the stock purchase
agreement. See note 16.

 Unaudited Pro Forma Balance Sheet

(11) Stock Option Plans

 Engage 1995 Equity Incentive Plan

   In August 1995, the Company's Board of Directors and Stockholders approved
the 1995 Equity Incentive Plan (the "1995 Plan"). Under the 1995 Plan, non-
qualified stock options or incentive stock options may be granted to the
Company's or its affiliates' employees, as defined. The Board of Directors
administers this plan, selects the individuals to whom options will be granted,
and determines the number of shares and exercise price of each option. Options
granted under the 1995 Plan typically vest over a four year period, with 25% of
options granted becoming exercisable one year from the date of grant and the
remaining 75% vesting monthly for the next thirty-six (36) months. The
following table reflects activity and historical prices of stock options under
the Company's 1995 Plan for the three years ended July 31, 1998 and the nine

 CMGI 1986 Stock Option Plan

   Certain Engage employees have been granted stock options under the CMGI 1986
Stock Option Plan (the "1986 Plan"). Options under the 1986 Plan are granted at
fair market value on the date of the grant and are generally exercisable in
equal cumulative installments over a four-to-ten year period beginning one year
after the date of grant. Outstanding options under the 1986 Plan expire through
2007. Under the 1986 Plan, non-qualified stock options or incentive stock
options may be granted to CMGI's or its subsidiaries' employees, as defined.
The Board of Directors of CMGI administers this plan, selects the individuals
to whom options will be granted, and determines the number of shares and
exercise price of each option. The following table reflects activity and
historical prices of stock options granted to Company employees under CMGI's
1986 Plan for the three years ended July 31, 1998 and the nine months ended
April 30, 1999:

   SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), sets
forth a fair-value based method of recognizing stock-based compensation
expense. As permitted by SFAS No. 123, the Company has elected to continue to
apply APB No. 25 to account for its stock-based compensation plans. Had
compensation cost for awards in fiscal 1996, 1997 and 1998 under the Company's
stock-based compensation plans been determined based on the fair value method
set forth under SFAS 123, the pro forma effect on the Company's net loss would
have been as follows:

   The fair value of each stock option grant has been estimated on the date of
grant using the Black-Scholes option pricing model with the following weighted
average assumptions for fiscal 1996, 1997 and 1998, and the nine moneths ended
April 30, 1999, respectively: volatility of 80.30%, 66.69%, 90.07% and 100.00%;
risk-free interest rate of 5.81%, 6.19%, 5.48% and 5.16%; expected life of
options of 4.0, 4.0, 3.4 and 2.5 years; and 0% dividend yield for all years.
The weighted average fair value per share of options granted during fiscal
1996, 1997 and 1998 and the nine months ended April 30, 1999 was $0.10, $0.34,
$0.86 and $1.42, respectively.

(12) Comprehensive Income

   Effective August 1, 1998, the Company adopted Statement of Financial
Accounting Standard ("SFAS") No. 130, "Reporting Comprehensive Income." This
statement requires that all components of comprehensive income be reported in
the financial statements in the period in which they are recognized. The
components of comprehensive loss for the Company include net loss, the net
change in foreign currency translation adjustments and unrealized holding gains
and losses on available-for-sale securities. The financial statements of prior
periods have been reclassified for comparative purposes.

(13) Concentration of Credit Risk

   Amounts included in the consolidated balance sheets for accounts receivable,
debt to CMGI, accounts payable and accrued expenses approximate their fair
value due to their short maturities. Financial instruments that potentially
subject the Company to credit risk consist primarily of accounts receivable.
The Company performs periodic credit evaluations of its customers' financial
condition and generally does not require collateral or other security against
trade receivable balances; however, it does maintain reserves for potential
credit losses and such losses have been within management's expectations. The
Company's revenue for the year ended July 31, 1997 was derived from one
customer. Sales to three customers accounted for 20%, 12% and 11% of total
revenues for the year ended July 31, 1998. Sales to two customers accounted for
17% and 16% of total revenues for the nine months ended April 30, 1998 and
sales to one customer accounted for 10% of total revenues for the nine months
ended April 30, 1999. Accounts receivable at July 31, 1997 was due from one
customer. Accounts receivable due from three customers approximated 23%, 12%
and 12% of total accounts receivable at July 31, 1998. Accounts receivable from
two customers approximated 20% and 13% of total accounts receivable at April
30, 1999. The Company's customer base consists of geographically diverse
customers across many industries.

(14) Related Party Transactions

   CMGI has provided the Company with systems and related services ("enterprise
services") at amounts that approximated the fair value of services received in
each of the periods presented in these financial statements. The Company also
occupies facilities that are leased by CMGI, whereby CMGI charges the Company
for its share of rent and related facility costs through an allocation based
upon the company's headcount in relation to total headcount for all CMGI
companies located in the premises. The Company has also purchased certain
employee benefits (including 401(k) plan participation by employees of the
Company) and insurance (including property and casualty

consolidated balance sheets. See note 16. The following summarizes the expenses
allocated to the Company by CMGI for enterprise services, rent and facilities,
and human resources:

   In addition, beginning in fiscal 1997, the Company outsources data center
operations and management information services from CMGI and one of its
affiliates, for which fees were charged at estimated fair value of $1,162,000,
$889,000 and $1,633,000 during the years ended July 31, 1997 and 1998 and the
nine months ended April 30, 1999, respectively.

   The Company leases certain property and equipment from a subsidiary of CMGI.
Under the arrangement, the related party negotiates the terms and conditions of
the lease and obtains the assets to be leased. The related party bears all
liability for payment, and the Company is not financially obligated under the
leases. The Company is charged the actual lease fees paid by the related party,
plus an additional administrative charge that approximates the fair value of
the services received (see note 8).

   The Company sells its products and services to companies that CMGI has an
investment interest or a significant ownership interest. The Company sold no
products to related parties in fiscal 1996 and 1997. Total revenue realized
from sales to related parties were $235,000 and $1,364,000 for the fiscal year
ended July 31, 1998 and the nine months ended April 30, 1999. The related cost
of revenue is consistent with the costs incurred on similar transactions with
unrelated parties.

(15) Geographic Information

   The Company currently has offices in the United States and the United
Kingdom. The Company markets its products worldwide. Revenues are grouped into
three main geographic areas; United States, Europe and Rest of world. Revenue

(16) Subsequent Events

 Designation of Series C Convertible Preferred Stock

   In May 1999, the Board of Directors approved the designation of 2,000,000
shares of the Company's preferred stock as Series C Convertible Preferred Stock
("Series C Preferred Stock"). The Series C Preferred Stock is entitled to
receive noncumulative annual dividends, payable when, as and if declared at the
rate of 7% per annum. In the event of any liquidation, dissolution or winding
up of the Company, the Series C Preferred Stock ranks senior to the Series B
Preferred Stock and pari passu with the Series A Preferred Stock, and has a
liquidation preference equal to its purchase

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

price plus dividends computed at 7% per share per annum. Each share of Series C
Preferred Stock votes on an as-converted basis and is convertible at the option
of the holder into twenty shares of common stock, subject to certain
adjustments. Upon the closing of a qualifying initial public offering, all
outstanding shares of Series C Preferred Stock will convert into common stock.

Debt to CMGI

   In May 1999, the Company formalized its borrowing arrangement with CMGI and
executed a secured convertible demand note with CMGI dated February 1, 1999.
Advances accrue interest at the annual rate of 7%, and advances and accrued
interest may be prepaid without penalty. Advances outstanding under this note
are secured by substantially all assets and intellectual property of the
Company and principal, and accrued interest may be converted at the option of
CMGI into shares of Series C Preferred Stock. The number of Series C Preferred
shares to be issued upon conversion of each borrowing represented by the note
is based on the estimated fair value of the Company at the end of the quarter
in which such borrowing was made.

   In accordance with this arrangement, CMGI elected to convert advances and
accrued interest outstanding at April 30, 1999 in the amount of $37,447,000
into 413,564 shares of Series C Preferred Stock.

Authorized Share Increase and Stock Split

   In June 1999, the Board of Directors approved an increase in the number of
authorized common shares from 30,000,000 to 150,000,000. Upon approval of the
share increase, a two-for-one stock split was declared. All share data shown in
the accompanying consolidated financial statements have been retroactively
restated to reflect this split.

1999 Employee Stock Purchase Plan

   The 1999 Employee Stock Purchase Plan was adopted by the board of directors
in June 1999. The 1999 Employee Stock Purchase Plan provides for the issuance
of a maximum of 750,000 shares of common stock and will be administered by the
compensation committee. All employees of Engage whose customary employment is
for more than 20 hours per week and for more than 6 months in any calendar year
are eligible to participate in the 1999 Employee Stock Purchase Plan.

1999 Stock Option Plan for Non-Employee Directors

   The 1999 Stock Option Plan for Non-Employee Directors was adopted by the
board of directors in June 1999. Under the terms of the 1999 Stock Option Plan
for Non-Employee Directors, directors who are not employees of Engage or any
subsidiary of Engage and not affiliates of an institutional investor that owns
shares of Engage's common stock receive nonstatutory options to purchase shares
of Engage's common stock. A total of 250,000 shares of common stock may be
issued upon exercise of options granted under the plan. The board of directors
has discretion to establish the terms of options granted under the plan. All
options must have an exercise price equal to the fair market value of the
common stock on the date of grant.

Issuance of Common Shares to Compaq Computer

   In July 1999, the Company entered into an agreement with Compaq Computer
Corporation pursuant to which the Company will issue 938,000 shares of its
common stock to Compaq.

                         NOTES TO FINANCIAL STATEMENTS

                           December 31, 1997 and 1996

(1) Company Operations and Summary of Significant Accounting Policies

   (a) Nature of Business and Presentation

   Accipiter, Inc. (the "Company") develops and markets Internet application
software that enables web sites to deliver targeted advertising based on
specific demographic profiles and to track individual visitors on a web site.
Most of the Company's efforts since incorporation have been devoted to
obtaining capital and developing and testing products. Accipiter's clients are
both domestic and international organizations with web sites on the Internet.

   The Company was accounted for as a development stage enterprise in
accordance with Statement of Financial Accounting Standards No. 7, "Accounting
and Reporting by Development Stage Enterprises" in 1996. Operations commenced
in 1997.

 Interim Financial Statements

   The financial statements of Accipiter, Inc. as of March 31, 1998 and for the
three months ended March 31, 1997 and 1998 are unaudited. All adjustments and
accruals (consisting only of normal recurring adjustments) have been recorded
that, in the opinion of management, are necessary for a fair presentation.
Results of operations for the interim periods are not necessarily indicative of
the results for the full year.

   (b) Revenue Recognition

   The Company's revenue, which consists of license fees, software support and
consulting fees, is recognized in accordance with AICPA Statement of Position
91-1, "Software Revenue Recognition" (AICPA SOP 91-1). Revenue from license
fees is recognized upon shipment of the product and fulfillment of acceptance
terms, if any. Revenue from software support and consulting services is
recognized as services are provided.

   (c) Income Taxes

   Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss carryforwards. 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. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.

   (d) Property and Equipment

   Property and equipment, consist of computer and office equipment which is
being depreciated using the straight-line method over its estimated useful life
of five years for furniture and three years for office equipment.

   (e) Research and Development

   Research and development expenditures are expensed as incurred. Software
development costs are required to be capitalized when a product's technological
feasibility has been established either by completion of a detail program
design or a working model of the product and ending when a product is available
for general release to consumers. To date, attainment of technological
feasibility

                                ACCIPITER, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

of the Company's products and general release to customers have substantially
coincided. As a result, the Company has not capitalized any software
development costs since such costs have not been significant.

   (f) Use of Estimates

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

(2) Income Taxes

   There was no income tax benefit for the year ended December 31, 1997 and the
period from April 4, 1996 (inception) to December 31, 1996. The difference
between the actual tax and the expected benefit is as follows:

</TABLE>

   At December 31, 1997, the Company has net operating loss carryforwards
(NOL's) for federal income tax purposes of approximately $1,895,000 which
expire in varying amounts between 2011 and 2012. The Company has NOL's for
state tax purposes of approximately $1,895,000 which expire in varying amounts
between 2001 and 2002. Additionally, the Company has research and development
credits of approximately $23,000 which expire in varying amounts between 2009
and 2010. Due to the uncertainty regarding the ultimate realizability of the
Company's NOL's, a full valuation allowance has been provided such that
deferred tax assets are not recognized.

   The components of deferred tax assets and deferred tax liabilities as of
December 31, 1997 and 1996 are as follows:

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   The Tax Reform Act of 1986 contains provisions which limit the ability to
utilize net operating loss carryforwards in the case of certain events
including significant changes in ownership interests. If the Company's NOL's
are limited, and the Company has taxable income which exceeds the permissible
yearly NOL, the Company would incur federal income tax liability even though
NOL's would be available in future years.

(3) Note payable

   During December 1996, the holder of the preferred stock ("Investor")
advanced $250,000 in the form of a convertible note that accrued interest at
10%. The Investor advanced an additional $250,000 in 1997. The advances
totaling $500,000 were converted to 422,000 shares of Series A preferred stock
in 1997. Accrued interest of $3,485 was converted to 2,941 shares of Series A
preferred stock in 1997.

   During May 1997, the Investor advanced the Company $300,000 in the form of a
convertible note that accrued interest at 10% and which was subsequently
converted to 218,500 shares of Series B preferred stock. Accrued interest of
$5,610 was converted to 4,086 shares of Series B preferred stock in 1997.

(4) Capital Structure

   The Company is authorized to issue up 8,000,000 shares of $.01 par value
common stock and 4,250,000 shares of $.001 par value preferred stock, of which
1,735,299 shares have been designated as Series A convertible preferred stock
and 2,514,701 shares have been designated as Series B convertible preferred
stock.

Series A and B preferred stock ("preferred stock")

   The significant terms of the preferred stock are as follows:

   Dividends--The holders of the preferred stock are eligible to receive
dividends if and when declared by the Board of Directors of the Company. The
preferred stockholders' right to receive dividends is senior to that of common
stockholders.

   Liquidation Preference--The holders of preferred stock are senior to the
common shareholders in the event of liquidation. The Series A preferred
stockholders are entitled to receive a liquidation preference of $0.50 per
preferred share. The Series B preferred stockholders are entitled to receive a
liquidation preference of $1.373 per preferred share.

   Redemption and Conversion--Each share of preferred stock is convertible into
common stock at the rate of one common share to one preferred share. The
preferred stock is convertible upon the occurrence of an initial public
offering or at the option of the preferred stockholders. In the event the
preferred stock has not been redeemed or converted prior to July 1, 2002, the
shares are redeemable at the option of the stockholders, with one-third payable
on July 1, 2002, one-third payable on July 1, 2003, and one-third payable on
July 1, 2004, from legally available funds on a pro rata basis at the
liquidation preference.

   Voting Rights--The holders of the preferred stock are generally entitled to
vote based on the number of common shares they would receive upon conversion.

Stock Options

   On May 30, 1996, the Board of Directors adopted a stock option plan to
create an additional incentive for key employees, directors and consultants or
advisors. At December 31, 1997, 1,050,000 common shares were authorized for
issuance to be granted within 10 years of plan adoption. The

                                ACCIPITER, INC.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)

Company issued incentive stock options to acquire 796,250 shares of common
stock to employees and nonqualified options to acquire 71,864 common shares to
a director during the period from adoption of the plan to December 31, 1997.
The exercise price for options issued through February 1997 was set at
$0.0667. The exercise price for options issued after February 1997 was set at
$0.1373. Exercise prices were estimated to approximate the market value of the
common stock on the date of issuance. Generally, the options provide that
after a six month waiting period, vesting occurs ratably each month over
forty-two months. At December 31, 1997, options for 143,481 shares were
vested. No options have been exercised as of December 31, 1997.

   The Company accounts for its stock option plan in accordance with the
provisions of Accounting Principles Board ("APB") Opinion No. 25, Accounting
for Stock Issued to Employees, and related interpretations. As such,
compensation expense is recorded on the date of grant only if the current
market price of the underlying stock exceeds the exercise price.

   SFAS No. 123, Accounting for Stock-Based Compensation, permits entities to
recognize compensation expense over the vesting period using the fair value of
all stock-based awards on the date of grant. Alternatively, SFAS No. 123 also
allows entities to continue to apply the provisions of APB Opinion No. 25 and
provide pro forma net income and earnings per share disclosures for employee
stock option grants made in 1996 and future years as if the fair-value-based
method defined in SFAS No. 123 had been applied. The Company has elected to
apply the provisions of APB Opinion No. 25.

   The fair value of each option granted is estimated on the date of the grant
using the Black-Scholes option pricing model with the following assumptions
used for the grants in 1997 and 1996; dividend yield of 0%; expected
volatility of 0%; risk-free interest rate of 5.0% to 6.0%; and expected lives
of 10 years for each option. The pro forma disclosures have not been included
as the fair value of options granted for the year ended December 31, 1997 are
immaterial.

   A summary of the status of the Company's stock plan as of December 1997 and
1996 and changes during the years then ended is presented below:

(6) Subsequent Event

   On March 11, the Company and CMGI entered into a letter agreement,
providing for the acquisition of the Company by CMGI. The transaction closed
on April 8, 1998. The agreement provides that the Company will be merged with
a newly created wholly-owned subsidiary of CMGI. It also provides that each
common share of the Company and stock equivalents determined on a fully-
diluted as-converted basis will be converted into the right to receive
$35,000,000 worth of CMGI common stock, price determined on March 2, 1998 as
$55.50 per share. If the price of common stock of CMGI fluctuates according to
the agreement at the acquisition date, the number of shares may vary
accordingly. The letter agreement provides that the acquisition is subject to
the execution of a definitive agreement and to the occurrence or waiver of
certain conditions.

   As noted in note 4, the Company entered into a consulting agreement with a
director in June 1997. Payments under this agreement in 1997 totaled $42,000.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders
Internet Profiles Corporation:

In our opinion, the accompanying balance sheets and the related statements of
operations, of stockholders' equity (deficit) and of cash flows present fairly,
in all material respects, the financial position of Internet Profiles
Corporation at December 31, 1998 and 1997 and the results of its operations and
cash flows for the years then ended, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has incurred recurring losses from operations
and has an accumulated deficit of $27,768,378 at December 31, 1998 that raise
substantial doubt as to its ability to continue as a going concern.
Management's plans in regard to those matters are also described in Note 1. The
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS

1. Formation and Business of the Company and Basis of Presentation of the
   Financial Statements

   Internet Profiles Corporation (the "Company") was incorporated in California
on August 4, 1994 as a provider of software and services that help customers
analyze and obtain independent verification of Web site activity. The Nielsen
I/PRO Netline service provides an outsourced solution for comprehensive site
analysis and reporting directly to the customer's desktop. Nielsen I/PRO
I/Audit provides third party verification of web site traffic, validating a web
site as an advertising vehicle for media buyers. Customized measurement
services are also available, which provide a comprehensive and customized array
of measurement and analysis for E-Commerce, ad-supported and corporate
web sites.

   The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. The Company has suffered recurring
losses from operations and at December 31, 1998, the Company had an accumulated
deficit of $27,768,378. The Company expects to incur further losses related to
its operations. The Company's operations are currently funded by proceeds from
the sale of convertible debt. In order to fund continuing operations, the
Company entered into a definitive purchase agreement as of March 1, 1999,
whereby the Company will be acquired by CMGI, Inc. (see Note 11).

2. Summary of Significant Accounting Policies

Use of estimates

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

Cash and cash equivalents

   The Company considers all highly liquid investments purchased with an
original or remaining maturity of less than three months at the date of
purchase to be cash equivalents. Substantially all of its cash and cash
equivalents are custodied with one major financial institution.

Fair value of financial instruments

   Carrying amounts of certain of the Company's financial instruments including
cash and cash equivalents, accounts receivable, accounts payable, accrued
expenses and other liabilities approximate fair value due to their short
maturities. Based upon borrowing rates currently available to the Company for
loans with similar terms, the carrying value of capital lease obligations
approximate fair value.

Revenue recognition

   The Company generally recognizes revenue on its Netline product ratably over
the subscription period as the services are provided. The Company recognizes
revenue on its I/Audit product upon delivery of its Web site audit reports. The
Company provides an allowance for sales returns and doubtful accounts
receivable, where appropriate.

                         INTERNET PROFILES CORPORATION

                  NOTES TO FINANCIAL STATEMENTS--(Continued)

Depreciation and amortization

   Property and equipment are stated at cost and are depreciated on a
straight-line basis over the estimated useful lives, which are generally three
years. Software and marketing database licenses are carried at cost, which is
amortized on a straight-line basis over their estimated useful lives,
generally four years. Upon disposal, the assets and related accumulated
depreciation or amortization are removed from the Company's accounts and the
resulting gains or losses are reflected in the current operations.

Research and development costs

   Research and development costs are charged to operations as incurred.
Software development costs are capitalized beginning when a product's
technological feasibility has been established and ending when a product is
available for general release to customers. To date, the establishment of
technological feasibility of the Company's products and general release have
substantially coincided, and as a result, the Company has not capitalized any
software development costs.

Reclassifications

   Certain prior-year amounts have been reclassified to conform with the
current-year presentation.

Income taxes

   The Company accounts for income taxes under Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes." Under
this method, deferred tax assets and liabilities are determined based on the
differences between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to affect taxable income. Valuation allowances are
established when necessary to reduce deferred taxes to the amounts expected to
be realized.

Concentration of credit risk

   Financial instruments which potentially subject the Company to
concentration of credit risk consist principally of cash and cash equivalents
and accounts receivable. Substantially all of its cash and cash equivalents
are custodied with one major financial institution. Deposits held with banks
may exceed the amount of insurance provided on such deposits. Generally these
deposits may be redeemed upon demand and therefore, bear minimal risk.

   The Company performs Web site audit services to customers throughout the
United States. One customer, a corporate partner and investor, accounted for

Certain risks and uncertainties

   The Company's products and services are concentrated in a single segment in
the internet industry which is characterized by rapid technological advances,
changes in customer requirements and evolving regulatory requirements and
industry standards. The success of the Company depends on the management's
ability to anticipate or to respond quickly and adequately to technological
developments in its industry, changes in customer requirements or changes in
regulatory requirements or industry standards. Any significant delays in the
development or introduction of products or services could have a material
adverse effect on the Company's business and operating results.

   The Company also entered into a loan and security agreement for equipment
purchases with a financial institution under which the Company borrowed an
aggregate amount of $768,050. The equipment line consists of advances for the
acquisition of equipment through October 1997. The equipment loan bears
interest at the bank's prime rate plus 0.5% (9.00% and 8.25% at December 31,
1997 and 1998, respectively) and is payable in monthly installments ending
December 2000. The loan is secured by substantially all assets of the Company.

   Future minimum payments under this loan agreement are as follows:

   Year ended December 31,

</TABLE>

  The agreement in respect of the loan contains certain covenants related to
the Company's quick ratio, liquidity and profitability. Default on any
covenant may affect the commitment by the bank to continue to lend under the
agreement and, if not corrected, could accelerate the maturity of any
borrowings outstanding under the agreement. At December 31, 1998, and at
various dates throughout the year, the Company was not in compliance with
certain covenants. The Company has obtained waivers in respect of non-
compliance as of December 31, 1998. The Company was in default of certain
covenants subsequent to December 31, 1998, which if not corrected, could
accelerate the maturity of borrowings still outstanding. Therefore, all
balances outstanding at December 31, 1998 have been classified as current.

   In November and December 1998, the Company obtained a series of bridge
loans totaling approximately $1,999,721 from a group of existing preferred
shareholders. The notes bear interest at an annual rate of 6% which accrues
daily and is added to the principal balance, with principal and

interest to be repaid, in total, six months after the commencement of the note
term. On the sale or merger of the Company, the loans would have certain
repayment preferences involving either conversion of the notes to a new series
of preferred stock, or repayment of the loans prior to distribution of any
funds to holders of any class of Company preferred or common stock.

6. Commitments

   The Company leases three facilities under noncancelable operating leases
expiring in September 1999 and July 2002. The Company is responsible for
certain taxes, maintenance costs and insurance under these leases. Future

   In 1995 the Company entered into an agreement with a corporate partner and
investor for the sale and marketing of existing internet usage measurement and
analysis products and services developed by the Company. Under this agreement,
the Company is required to pay commissions on net revenues from products sold
in the US primarily through the efforts of this corporate partner, as well as
on products sold through the efforts of the Company. Revenues related to this
agreement from products sold primarily through the efforts of this corporate
partner for the years ended December 31, 1997 and 1998 totaled $390,995 and
$363,508, respectively. Commissions incurred relative to this agreement on
products sold through the efforts of the Company for the years ended December
31, 1997 and 1998 totaled $146,188 and $236,454 respectively. The agreement
expired in September 1998 and was extended for an additional year, and may
continue to be extended by the mutual agreement of the parties. As of December
31, 1997 and 1998 under this agreement, amounts payable to the corporate
partner totaled $259,688 and $236,454 respectively, and amounts receivable from
the corporate partner totaled $222,209 and $268,090, respectively.

   In October 1997, the Company agreed to pay $175,000 to a software vendor for
a software license, payable in six monthly installments of $29,167 per month,
with the first such payment being due and payable upon the earlier of ten days
following the date upon which the vendor files a petition in bankruptcy, or 390
days from October 31, 1997. No payments related to this agreement were made
during the year ended December 31, 1998. During January 1999, the balance
outstanding on this agreement was paid in full to the software vendor.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


Liquidation

   Series D preferred stock will be entitled to receive in preference to the
holders of the Series A, B and C preferred stock and the common stock an amount
per share equal to $0.339. The maximum aggregate amount the holders of the
Series A, B and C preferred stock will be entitled to receive is $4,861,463.
The respective liquidation preferences of the Series A, B and C preferred stock
adjust annually on May of each year to provide the Series C preferred with an
annual increase in its liquidation preference amount of five percent. Any
assets remaining after the distribution to the Series A, B, C and D preferred
stock will be distributed pro-rata to the holders of the common stock.

Mergers

   A merger, reorganization or sale of all or substantially all of the assets
of the Company in which more than 50% of the outstanding stock of the Company
is exchanged, shall be deemed to be a liquidation, dissolution or winding up.

Voting

   The holders of each share of Series A, B, C and D preferred stock shall have
the right to one vote for each share of common stock into which such preferred
stock could then be converted, and with respect to such vote, such holder shall
have full voting rights and powers equal to the voting rights and powers of the
holders of common stock.

Conversion

   Each share of Series A, B, C and D preferred stock, at the option of the
holder, may be converted into the number of fully paid and nonassessable shares
of common stock as is determined by dividing the conversion price per share in
effect for the preferred stock at the time of conversion into the per share
conversion value of such shares. The initial conversion price per share and the
per share conversion value of Series A, B, C and D preferred stock are $0.285,
$0.57, $2.47 and $0.339 per share, respectively. The initial conversion price
of preferred stock is subject to adjustment from time to time. The number of
shares into which a share of preferred stock is convertible is referred to as
the conversion rate of such series.

   Conversion is automatic at its then effective conversion rate immediately
upon a closing of a firm commitment underwritten public offering pursuant to an
effective registration statement under the Securities Act of 1933, as amended,
covering the offer and sale of equity securities.

Common stock

   The Company issued 1,000,000 shares of its common stock to the founders
under a stock purchase agreement. Each share of common stock is entitled to one
vote. The holders of common stock are also entitled to receive dividends
whenever funds are legally available and when declared by the Board of
Directors, subject to the prior rights of holders of all classes of stock
outstanding. As of December 31, 1998 and 1997, no dividends have been declared.

Stock issued in exchange for in-process technologies

   In November 1997, the Company acquired the rights to certain technologies
which were previously held by two unrelated companies. In connection with the

111,214 shares of common stock at fair value of $162,000 and $83,411,
respectively. These amounts were immediately expensed to the statement of
operations as part of the expenses for research and development.

are full recourse promissory notes bearing interest at 6%, and are
collateralized by the stock issued upon exercise of the stock options. Interest
is payable in arrears, with both interest and principle being due and payable
on the fourth anniversary of the date of the making of the note. Should certain
circumstances occur, the Company has the right to repurchase any of the shares
related to the early exercise of unvested options described above.

Stock Options

   The Company has adopted the 1995 Stock Option Plan (the "Plan") under which
incentive stock options may be granted to employees and nonstatutory stock
options may be granted to employees and consultants. In December 1997, the
Company's Board of Directors increased the number of common stock shares
reserved for issuance under the 1995 Stock Option Plan to 10,030,095.

   The Board of Directors may issue incentive stock options to employees and
nonstatutory stock options to consultants or employees. The Board of Directors
has the authority to determine to whom options will be granted, the number of
shares, the term and exercise price (which cannot be less than fair market
value at date of grant for incentive stock options or 85% of fair market value
for nonstatutory stock options). If an employee or person owns stock
representing more than 10% of the outstanding voting shares, the price of each
share shall be at least 110% of fair market value, as determined by the Board
of Directors. Stock options generally expire ten years from the date of grant.
Options granted under the Plan generally become exercisable starting one year
after the date of grant, with 25% of the shares subject to the option becoming
exercisable at that time and an additional 1/16 of such shares becoming
exercisable each quarter thereafter.

   Activity under the Plan is as follows:

Pro forma stock-based compensation

   During October 1995, the Financial Accounting Standards Board issued
Statement No. 123 ("SFAS No. 123"), "Accounting for Stock-Based Compensation,"
which establishes a fair value based method of accounting for stock-based
compensation plans. The Company has chosen to continue to account for employee
stock options under APB Opinion No. 25, "Accounting for Stock Issued to
Employees" with disclosure of pro forma information concerning its stock option
plan in accordance with SFAS No. 123. The following disclosures are provided
pursuant to SFAS No. 123:

   Fair value of each option grant is estimated on the date of the grant using
the Black-Scholes option pricing model with the following weighted average
assumptions used for grants in 1997 and 1998.

</TABLE>

   Due to the uncertainty surrounding the realization of the favorable tax
attributes in future tax returns, the Company has placed a valuation allowance
against its otherwise recognizable net deferred tax asset. The valuation
allowance increased by $2,616,592 in 1997 and $2,400,362 in 1998.

   As of December 31, 1998, the Company has net operating loss carryforwards
of approximately $25,071,000 and $17,891,000 for federal and California state
tax purposes, respectively. Such carryforwards expire in varying amounts
through the year 2018 if not used before such time to offset future taxable
income or tax liabilities.

   Due to changes in the Company's ownership, the amount of net operating loss
carryforwards available to offset future federal and state taxable income or
tax may be limited by Internal Revenue Code (IRC) Section 382. The amount of
such limitation, if any, has not been determined.

9. Sale of Technology

   In October 1998, the Company sold the rights to one of its internet
properties in exchange for cash proceeds of $160,000 and certain limited
future advertising rights valued at $25,000, resulting in a gain of $185,000.

10. Employee Benefit Plan

   Essentially all Company employees are covered by a Company-sponsored 401(k)
plan, which qualifies under Section 401(k) of the Internal Revenue Code of
1986, as amended. Each eligible

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

employee may elect to contribute to the plan, through payroll deductions, up to
15% of compensation, subject to certain limitations. The Company, at its
discretion, may make additional contributions. No such additional contributions
were made during the years ended December 31, 1997 or 1998.

11. Subsequent Events

   In February 1999, the Company transferred its rights to certain technologies
used in measuring and reporting the results of advertising campaigns in
exchange for cash proceeds of $300,000. This amount is subject to increase if
certain performance goals are met during 1999. The entire purchase price was
recorded as a gain, as, in compliance with its normal accounting policies, the
Company had previously expensed all costs associated with the development of
this technology.

   On March 1, 1999, the Company signed a binding letter of intent to be
acquired by CMGI, Inc. and Engage Technologies, Inc. Upon signing of a
definitive purchase agreement, the Company will become a wholly owned
subsidiary of Engage Technologies, Inc., which is in turn a majority owned
subsidiary of CMGI, Inc. A portion of the purchase price will be used to retire
certain liabilities, including the outstanding balance on a loan and security
agreement with a financial institution, attorney and broker fees related to the
transaction, and certain other commitments. Approximately 10% of the remaining
purchase price will be used to retire a portion of the outstanding common stock
of the Company. The remainder, in the form of various forms of equity vehicles
available to CMGI, Inc., will be used to retire the balance of the Company's
common and preferred stock.

   Shares sold by the underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus.
Any shares sold by the underwriters to securities dealers may be sold at a
discount of up to $0.63 per share from the initial public offering price. Any
such securities dealers may resell any shares purchased from the underwriters
to other brokers or dealers at a discount of up to $0.10 per share from the
initial public offering price. If all the shares are not sold at the initial
public offering price, the representatives may change the offering price and
the other selling terms.

   Engage and its directors, officers and persons beneficially owning more than
98% of its common stock have agreed with the underwriters not to dispose of or
hedge any of their common stock or securities convertible into or exchangeable
for shares of common stock during the period from the date of this prospectus
continuing through the date 180 days after the date of this prospectus, except
with the prior written consent of the representatives. This agreement does not
apply to gifts or transfers to affiliates or transactions under any existing
employee benefit plans. Please see "Shares Eligible for Future Sale" for a
discussion of various transfer restrictions.

   An aggregate of 300,000 shares of common stock offered by this prospectus
have been reserved for purchase from the

                                      U-1
<PAGE>

underwriters through a directed share program by customers, suppliers,
distributors and other of Engage's business partners. An aggregate of 300,000
shares of common stock offered by this prospectus have been reserved for
purchase from the underwriters through a directed share program by employees of
Engage. An aggregate of 600,000 shares of common stock offered by this
prospectus have been reserved for purchase from the underwriters through a
directed share program by United States shareholders of CMGI, who hold more
than 100 shares of CMGI stock as of June 15, 1999 and who have access to the
Internet and a personal e-mail address. Such sales will be at the initial
public offering price. There can be no assurance that any of the reserved
shares will be so purchased. The number of shares available for sale to the
general public in the offering will be reduced by the number of reserved shares
sold. Any reserved shares not purchased will be offered to the general public
on the same basis as the other shares offered by this prospectus.

   The CMGI directed share program is being administered by Wit Capital.
Purchases of the reserved shares are to be made through an account at Wit
Capital in accordance with Wit Capital's procedures for opening an account and
transacting in securities. In addition, Wit Capital is an underwriter of
additional shares in the offering. A prospectus in electronic format is being
made available on a Web site maintained by Wit Capital. Other than the
prospectus in electronic format, the information on Wit Capital's Web site and
any information provided on any other Web site maintained by Wit Capital is not
part of this prospectus and has not been approved or endorsed by Engage or any
underwriter and should not be relied upon by prospective investors.

   Prior to this offering, there has been no public market for the shares. The
initial public offering price was negotiated among Engage and the
representatives. The primary factors that Engage and the representatives
considered in determining the initial public offering price of the shares, in
addition to prevailing market conditions, were Engage's historical performance,
estimates of the business potential and earnings prospects of Engage, an
assessment of Engage's management and the consideration of the above factors in
relation to market valuation of companies in related businesses.

   Engage's common stock has been approved for quotation on the Nasdaq National
Market under the symbol "ENGA".

   In connection with this offering, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in this offering.
Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of the common
stock while this offering is in progress.

   The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because the representatives have repurchased shares
sold by or for the account of such underwriter in stabilizing or short covering
transactions.

   These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the
open market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on the Nasdaq
National Market, in the over-the-counter market or otherwise.

   The underwriters do not expect sales to discretionary accounts to exceed
five percent of the total number of shares offered.

   Engage estimates that its share of the total expenses of this offering,
excluding underwriting discounts and commissions, will be approximately
$1,275,000.

   Engage has agreed to indemnify the several underwriters against liabilities,
including liabilities under the Securities Act of 1933. In addition, Hambrecht
& Quist has agreed to indemnify both Engage and the other underwriters for
liabilities arising out of the distribution of written materials that Hambrecht
& Quist provided to approximately 80 Engage employees that Engage had
designated as potential purchasers of up to 300,000 shares of common stock in
this offering through a directed share program.
