                               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

                                       3
<PAGE>

   to perform sophisticated analyses of the behavior and interests of their
   Web site visitors.

   As of April 30, 1999, Engage had sold its products and services to
approximately 300 customers.

                             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:

  Exploit position as innovator in profiling technology. 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 and
   industry-specific markets such as the automotive and retail markets.

  Cross-sell family of Engage products and services. We intend to cross-sell
   our products and services to our existing installed base of customers.

  Maintain position as trusted leader in Internet privacy. We plan to maintain
   our commitment and leadership regarding issues of consumer privacy on the
   Internet.

                                Our History

   Engage was incorporated in Delaware on July 18, 1995. 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
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 $47.2 million since inception in

1995 and expects to continue to incur significant losses for the foreseeable
future. Engage operates in a highly competitive market and it may not achieve
profitability. A material portion of Engage's revenue to date has derived from
sales of products and services to affiliates of CMGI.

   Our principal executive offices are located at 100 Brickstone Square,
Andover, MA 01810. Our telephone number at that location is 978-684-3884. Our
Internet address is www.engage.com. The information contained on our Web site

                                  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 $47.2
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

   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. Decisions by our major customers not to contribute their data
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. Although

                                       7
<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 industry-specific markets

   We plan to develop Engage Knowledge data services that are tailored for the
requirements of specific markets, such as the automotive, retail and other
industry-specific 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 83%
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

                                       8
<PAGE>


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 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 and the first
nine months of fiscal 1999, sales of products and services to affiliates of
CMGI accounted for $235,000 and $1.4 million, respectively, 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.
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. 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" 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.

   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.
The European Union has recently adopted a directive addressing

                                       9
<PAGE>

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. 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. This growth has
placed a significant strain on our managerial, operational and financial
resources. 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.

   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

                                       10
<PAGE>

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 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.


                                       11
<PAGE>

   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
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

                                       12
<PAGE>

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.

   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

                                       13
<PAGE>


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  ,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. 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 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

   After this offering, there will be outstanding 45,973,798 shares of our
common stock, or 46,873,798 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
39,973,798 shares of common stock held by existing stockholders, 39,281,464 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

                                       14
<PAGE>

days after the date of this prospectus, subject in the case of shares held by
affiliates to compliance with applicable volume restrictions. Sales of a large
number of shares could have an adverse effect on the market price of our common
stock.



               You will suffer immediate and substantial dilution

   The initial public offering price per share will significantly exceed the
net tangible book value per share. Investors purchasing shares in this offering
will suffer dilution of $8.84 per share from their investment.

                                USE OF PROCEEDS

   Engage estimates that the net proceeds from its sale of 6,000,000 shares of
common stock will be $54.8 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 $63.2 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

  . 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
    application of the estimated net proceeds from the sale of common stock
    in this offering, assuming an initial public offering price of $10.00 per
    share, 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 (deficit) of Engage as of April 30,
1999 was approximately ($1.4) million, or approximately $(.03) per share of
common stock. Pro forma net tangible book value (deficit) 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 and the two-for-one stock split. After giving effect to the sale of the
common stock offered by Engage in this offering at an assumed initial public
offering price of $10.00 per share, 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 $53.4 million or approximately $1.16 per pro forma share of
common stock. This represents an immediate increase in net tangible book value
of $1.19 per share to Engage's existing stockholders and an immediate dilution
in net tangible book value of $8.84 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, I/PRO 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
provides notice of termination.

   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.

                                       20
<PAGE>


   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 $29.5 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 $1.5 million in cash, 49% of the shares
of Engage Technologies Japan, a joint venture with Sumitomo Corporation in
Japan. The joint venture was established to sell Engage's products and services
in Japan. This investment is being accounted for under the

                                       21
<PAGE>


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 $30.3 million, consisting of
$1.6 million in net cash, $20.9 million in CMGI shares and $7.8 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 $24.8 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 performance goals are met relating to the
gross revenue of I/PRO for the year ended March 31, 2000; data contributed to
the Engage knowledge database as of March 31, 2000; and various employees of
I/PRO continuing employment with Engage. 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'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,
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 $47.2 million. 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.

                             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

                                       22
<PAGE>


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.

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 $6.0 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 $6.7 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.

                                       23
<PAGE>


   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 $1.1 million in the nine months ended April 30, 1998 to
$2.8 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 $318,000 in the nine months ended April 30, 1998 to $3.2
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.

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 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. 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.

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.

                                       24
<PAGE>


   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 $2.3 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.

   Amortization of Goodwill and Other Intangibles. Amortization of goodwill and
other intangibles assets was $1.3 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.

                     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, Accipter 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
                                       25
<PAGE>


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
during fiscal 1998 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 this offering, will be sufficient to meet its
anticipated needs for working capital and capital expenditures on both a short-
term and a long-term basis for at least the 12 months following the date of
this prospectus. However, Engage may need to raise additional

                                       26
<PAGE>

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. 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
$29.5 million. In August 1998, Accipiter merged with Engage in a 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 31% 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 (the ability to operate
during a system failure) and scalability (the ability to expand capacity), (2)
an object-oriented user interface (a screen display that enables users to
easily operate a computer program), (3) application programming interfaces
(which enable a program to exchange data with other programs) and (4) a new
report engine (which is a component that generates reports).

   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 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

                                       27
<PAGE>


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 (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 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 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
$30.3 million. The portion of the purchase price allocated to in-process
research and development was $4.5 million, or approximately 15% 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 for the fault tolerance, scalability and
data processing efficiency that may be required 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 (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

                                       28
<PAGE>


forecast period, revenue was predicted to grow at rates comparable to the
growth of Internet 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 e-commerce (which is
supported by independent market data), 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 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. 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 (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 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

                                       30
<PAGE>


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 June 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 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.

                                    BUSINESS

                                     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.

                                       32
<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;

                                       33
<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

   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 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 algorithims 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.

   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, that the use of Engage profiles to
target advertisements can achieve click-through rates (the proportion of users
who click on an advertisement) greater than those achieved by untargeted
advertisements. 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 equal to or
greater than 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

                                       35
<PAGE>

or customers' internally developed solutions, allowing customers flexibility as
the uses of profiling and related applications develop and evolve.

   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:

Exploit Position as Innovator in Profiling Technology

   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

                                       36
<PAGE>


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 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.

immediately above it pointing upward at a box labelled "Engage or Third-Party
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 specific markets, such as 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

                                       37
<PAGE>

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 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.

Cross-sell 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 Trusted Leader in 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.

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
(currently stored as a browser cookie on the Web user's computer) to
distinguish each Web visitor. 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 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

                                       40
<PAGE>

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
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.

                                       41
<PAGE>

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 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.

                                       42

   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 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.

Consulting, Maintenance and Support Services

   Engage offers comprehensive services and product support to its customers.
Engage's service and support organization, consisting of 46 service
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.

                             Customer Case Studies

   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
                                       44
<PAGE>

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 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

                                       45
<PAGE>

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
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 has been designed to
operate anonymously and 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
(currently stored as a browser cookie on the Web user's computer) 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. 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.

                                      46
<PAGE>


   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 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

                                       47
<PAGE>

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 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,
                                       48
<PAGE>

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 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.

   Each executive officer is elected by, and serves at the discretion of, the
board of directors. Each of Engage's executive officers and directors, other
than nonemployee directors, devotes his full time to the affairs of Engage.
There are no family relationships among any of the directors or executive
officers of Engage.

                               Board Committees

   Engage has an audit committee and compensation committee of the board of
directors. The audit committee reviews the results and scope of audits and
other services provided by Engage's independent accountants. The audit
committee also reviews Engage's system of internal accounting and financial
controls. The audit committee consists of Messrs. Bennett, Goldman and
Hajducky.

   The compensation committee of the board of directors reviews and recommends
to the Board the compensation and benefits of all executive officers of
Engage, administers Engage's stock option plans and establishes and reviews
general policies relating to compensation and benefits of employees of Engage.
The compensation committee consists of Messrs. Bennett, Goldman and Wetherell.
Except as set forth in "Transactions and Relationship Between Engage and
CMGI", no interlocking relationships exist between Engage's board of directors
or compensation committee and the board of directors or compensation committee
of any other company.

                             Director Compensation

   Non-employee directors are reimbursed for their reasonable out-of-pocket
expenses incurred in attending meetings of the board of directors or of any
committee thereof. Engage intends to grant Mr. Evans an option to purchase
50,000 shares of its common stock, to vest over a five-year period, at an
exercise price of $2.38 per share. Mr. Goldman has been granted an option to
purchase 100,000 shares of Engage common stock, vesting over a four-year
period, at an exercise price of $0.24 per share. Mr. Bennett has been granted
an option to purchase 50,000 shares of Engage common stock, vesting over a
four-year period, at an exercise price of $4.19 per share.

   In May 1999, Engage and Mr. Evans entered into a consulting, invention and
non-disclosure agreement under which Mr. Evans provides programming and other
technical services to Engage. This agreement may be terminated at any time upon
90 days notice by Mr. Evans or Engage.

   No director who is an employee of Engage receives separate compensation for
services rendered as a director.

                             Executive Compensation

   The following table sets forth the total compensation paid or accrued for

                       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.

   The following table sets forth information regarding exercisable and
unexercisable stock options held as of July 31, 1998 by Messrs. Schaut and
Jaye. There was no public trading market for our common stock as of July 31,

determining the difference between the exercise price per share and an assumed
initial public offering price of $10.00 per share.

                                  Stock Plans

1995 Equity Incentive Plan

   The 1995 Equity Incentive Plan provides for the issuance of a maximum of
        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     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    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 83% 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.

                                       56
<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:

</TABLE>
   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, utilities and employee benefits
administration. Under this agreement, CMGI has also agreed to make available to
Engage at least    ,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.

   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

                                       57
<PAGE>


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

                         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.

                         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, there will be     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

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
45,973,798 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 39,973,798
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 39,281,464 shares of common stock,
including all of our officers and directors, 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 460,000 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

                                       63
<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

                          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.

                         ENGAGE TECHNOLOGIES, INC.

                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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)



 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.
Therefore, 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)

<PAGE>

                           ENGAGE TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

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 amounts due
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

 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 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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   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.

   Property and equipment recorded under capital leases amounted to
approximately $735,000 at April 30, 1999. Total accumulated amortization
related to these assets amounted to approximately $49,000 at April 30, 1999.
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 $1.47 million in cash, 49 percent
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

                           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 $29,489,000,
including acquisition costs of $198,000. The value of the CMGI shares included
in the purchase price was recorded net of a weighted average 15% 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 $9.2 million, or
approximately 31% 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 $30,264,000, 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 $7,794,000 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 $5.06 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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

   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 for the 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 (which is
supported by independent market data), 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.

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.

   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

   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

(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

a qualifying initial public offering, as defined in the stock purchase
agreement. See note 16.

 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

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.

   The components of comprehensive loss, net of income taxes, are as follows:

(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 insurance) through CMGI
and CMGI has guaranteed the Company's obligations under a lease for office
space used for research and development, sales and service operations. Amounts
due CMGI are included in "Debt to CMGI" on the 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,

(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 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 3,413,564 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 our board of directors
in June 1999, 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.

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. 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.

                         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

<PAGE>

                                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:

   In February 1997, the Company entered into a license agreement with CNET, a
customer. In connection with this agreement, the Company issued warrants to
purchase 181,862 shares of common stock at an initial exercise price of $2.50
per share. Such warrants vest during the two years after the date of the
agreement pursuant to certain conditions. The warrants are exercisable for two
years after the vesting period. If the license agreement between the Company
and CNET is terminated, the right to exercise these warrants will terminate
after 60 days.

   In June 1997, the Company entered into a consulting agreement with a
director of the Company. Pursuant to this agreement, the Company issued
warrants to purchase 60,000 shares of common stock at an initial exercise
price of $0.1373 per share. This warrant expires on June 12, 2002.

(5) Leases

   The Company has operating leases for office facilities, equipment, and
furniture. Rent expense under these leases and other month-to-month
arrangements totaled $163,407 and $14,311 in 1997 and 1996, respectively.

   The future minimum lease payments under the noncancellable lease agreements
are as follows:

(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.

(7) Related Party Transactions

   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.
The agreement ended in early 1998.

                       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.

<PAGE>

                         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
23% of accounts receivable as of December 31, 1998 and 1997.

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:

  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
minimum lease payments under the noncancelable operating leases are as follows:

   Rent expense for the years ended December 31, 1997 and 1998, and for the
three months ended March 31, 1998 and 1999 was $702,434, $578,839, $251,555 and
$271,693 respectively.

   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.

7. Stockholders' Equity

Convertible Preferred Stock

Dividends

   The holders of Series A, B, C and D preferred stock are entitled to
preferential noncumulative dividends at the rate of $0.0285, $0.111, $0.739 and
$0.0339 per share, respectively, if and when declared by the Board of
Directors. No dividends have been declared as of December 31, 1998 or 1997.

                   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
purchase of these in-process technologies, the Company issued 216,000 and
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.

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.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA

The unaudited pro forma combined condensed statements of operations of the
Company for the year ended July 31, 1998 and the nine months ended April 30,
1999 give pro forma effect to:

   .  the Accipiter acquisition;

   .  the I/PRO acquisition; and

  .  the related financing of the acquisitions above as if each had occurred
     as of August 1, 1997.

The results of operations of the Company for the fiscal year ended July 31,
1998 have been combined with the results of operations of Accipiter, Inc. for
the period August 1, 1997 through March 31, 1998 (the results of operations of
Accipiter for the period April 1, 1998 through July 31, 1998 are included in
the consolidated statement of operations of the Company), and the results of
operations of I/PRO for the twelve months ended September 30, 1998. In
addition, the results of operations for the Company for the nine months ended
April 30, 1999 have been combined with the results of operations of I/PRO for
the six months ended December 31, 1998. The results of operations of I/PRO for
July 1998 through September 1998 have been included in both unaudited pro forma
combined condensed statements of operations presented.

The Company has accounted for their acquisitions under the purchase method of
accounting. The total cost of businesses acquired including related fees and
expenses is allocated to the underlying tangible and intangible assets acquired
and liabilities assumed based on their respective fair values. The purchase
price allocations for the I/PRO acquisition included in the unaudited pro forma
data are preliminary. However, the Company does not expect that the final
allocation of the purchase price will be materially different from its
preliminary allocation.

The unaudited pro forma financial data are not necessarily indicative of the
results of operations or financial position of the Company had the transactions
assumed therein occurred, nor are they necessarily indicative of the results of
operations which may be expected to occur in the future. Furthermore, the
unaudited pro forma financial data are based upon assumptions that the Company
believes are reasonable and should be read in conjunction with the financial
statements and the accompanying notes included elsewhere in this prospectus.

       NOTES TO PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS

     Year ended July 31, 1998 and the nine months ended April 30, 1999

(a) Adjustment to in-process research and development reflects the elimination
    of $9,200 expensed to in-process research and development related to the
    acquisition of Accipiter in April, 1998 and $4,500 related to the
    acquisition of I/PRO in April 1999.

(b) Reflects additional goodwill and other intangible asset amortization
    expense related to the acquisition of Accipiter and I/PRO. For both
    Accipiter and I/PRO, goodwill is being amortized over five years, employee
    workforce is being amortized over two years and the tradename is being
    amortized over two years for Accipiter and five years for I/PRO, all using
    the straight-line method.

(c) Reflects additional amortization expense of developed technology acquired
    in the purchase of Accipiter and I/PRO. Developed technology is being
    amortized over five years using the straight-line method.

(d) Reflects a reduction in interest expense related to I/PRO borrowings that
    would have been settled by I/PRO had the acquisition been consummated at
    the beginning of the periods presented. This calculation was made based on
    actual amounts expensed by I/PRO in the related periods.

                             ---------------------

   If the underwriters sell more shares than the total number set forth in the
table above, the underwriters have an option to buy up to an additional 900,000
shares from Engage to cover such sales. They may exercise that option for 30
days. If any shares are purchased pursuant to this option, the underwriters
will severally purchase shares in approximately the same proportion as set
forth in the table above.

   The following table shows the per share and total underwriting discounts and
commissions to be paid to the underwriters by Engage. Such amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase additional shares.

   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 $    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 $    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 substantially all of its stockholders
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 underwriters through a directed share
program by customers, resellers and other parties having business relationships
with Engage. An aggregate of 300,000 shares of common stock offered by this
prospectus have been reserved for purchase from the underwriters through a
directed shares program by employees of Engage. 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.

                                      U-1

   Prior to this offering, there has been no public market for the shares. The
initial public offering price will be negotiated among Engage and the
representatives. Among the factors to be considered in determining the initial
public offering price of the shares, in addition to prevailing market
conditions, will be 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 has applied to list the common stock 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
$1,000,000.

   Engage has agreed to indemnify the several underwriters against liabilities,
including liabilities under the Securities Act of 1933.

Item 14. Indemnification of Directors and Officers.

The Delaware General Corporation Law and Engage's charter and by-laws provide
for indemnification of Engage's directors and officers for liabilities and
expenses that they may incur in such capacities. In general, directors and
officers are indemnified with respect to actions taken in good faith in a
manner reasonably believed to be in, or not opposed to, the best interests of
Engage and, with respect to any criminal action or proceeding, actions that the
indemnitee had no reasonable cause to believe were unlawful. Reference is made
to Engage's charter and by-laws filed as Exhibits 3.1 and 3.4 hereto,
respectively.

The Underwriting Agreement provides that the underwriters are obligated, under
some circumstances, to indemnify directors, officers and controlling persons of
Engage against some liabilities, including liabilities under the Securities Act
of 1933, as amended (the "Securities Act"). Reference is made to the form of
Underwriting Agreement filed as Exhibit 1.1 hereto.

Item 15. Recent Sales of Unregistered Securities.

In the three fiscal years preceding the filing of this registration statement,

<PAGE>

preferred stock to Sumitomo Corporation and Sumitomo Corporation of America at
a purchase price of $8.38 per share, for an aggregate consideration of
$2,000,000. Upon closing of the offering, the 238,597 outstanding shares of
Series B preferred stock will convert into 477,194 shares of common stock.
These shares were issued pursuant to Rule 506 under the Securities Act.

Engage issued a secured demand note to CMGI, dated February 1, 1999, in the
aggregate amount of $9,347,451, which is convertible into 164,371 shares of

convertible preferred stock will convert into 20 shares of common stock upon
the consummation of this offering. These shares were issued pursuant to Section
4(2) under the Securities Act.

In April 1999, Engage acquired I/PRO. As part of the acquisition, Engage issued
to I/PRO stockholders 1,010,184 shares of Engage common stock in exchange for

under the Securities Act.

for an aggregate purchase price of $31,682 pursuant to exercise of employee
options. These options and shares were issued pursuant to Rule 701 under the

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions described in Item 14 above, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes (1) to provide to the underwriters
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser; (2) that for purposes of determining
any liability under the Securities Act, the information omitted from the form
of prospectus filed as part of this registration statement in reliance upon
Rule 430A and contained in a form of prospectus filed by the registrant
pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be
deemed to be part of this registration statement as of the time it was declared
effective; and (3) that for the purpose of determining any liability under the
Securities Act, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

  As representatives of the several Underwriters
     named in Schedule I hereto,
85 Broad Street,

Ladies and Gentlemen:

     Engage Technologies, Inc., a Delaware corporation (the "Company"),
proposes, subject to the terms and conditions stated herein, to issue and sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an aggregate
of ........ shares (the "Firm Shares") and, at the election of the Underwriters,
up to ........ additional shares (the "Optional Shares") of Common Stock (par

Optional Shares that the Underwriters elect to purchase pursuant to Section 2
hereof being collectively called the "Shares").

     1.   The Company represents and warrants to, and agrees with, each of the
Underwriters that:

          (a)  A registration statement on Form S-1 (File No. 333-....) (the
"Initial Registration Statement") in respect of the Shares has been filed with
the Securities and Exchange Commission (the "Commission"); the Initial
Registration Statement and any post-effective amendment thereto, each in the
form heretofore delivered to you, and, excluding exhibits thereto, to you for
each of the other Underwriters, have been declared effective by the Commission
in such form; other than a registration statement, if any, increasing the size
of the offering (a "Rule 462(b) Registration Statement"), filed pursuant to Rule
462(b) under the Securities Act of 1933, as amended (the "Act"), which became
effective upon filing, no other document with respect to the Initial
Registration Statement has heretofore been filed with the Commission; and no
stop order suspending the effectiveness of the Initial Registration Statement,
any post-effective amendment thereto or the Rule 462(b) Registration Statement,
if any, has been issued and no proceeding for that purpose has been initiated or
threatened by the Commission (any preliminary prospectus included in the Initial
<PAGE>

Registration Statement or filed with the Commission pursuant to Rule 424(a) of
the rules and regulations of the Commission under the Act is hereinafter called
a "Preliminary Prospectus"; the various parts of the Initial Registration
Statement and the Rule 462(b) Registration Statement, if any, including all
exhibits thereto and including the information contained in the form of final
prospectus filed with the Commission pursuant to Rule 424(b) under the Act in
accordance with Section 5(a) hereof and deemed by virtue of Rule 430A under the
Act to be part of the Initial Registration Statement at the time it was declared
effective, each as amended at the time such part of the Initial Registration
Statement became effective or such part of the Rule 462(b) Registration
Statement, if any, became or hereafter becomes effective, are hereinafter
collectively called the "Registration Statement"; and such final prospectus, in
the form first filed pursuant to Rule 424(b) under the Act, is hereinafter
called the "Prospectus";

          (b)  No order preventing or suspending the use of any Preliminary
Prospectus has been issued by the Commission, and each Preliminary Prospectus,
at the time of filing thereof, conformed in all material respects to the
requirements of the Act and the rules and regulations of the Commission
thereunder, and did not contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; provided, however, that this representation and warranty
shall not apply to any statements or omissions made in reliance upon and in
conformity with information furnished in writing to the Company by an
Underwriter through Goldman, Sachs & Co. expressly for use therein;

          (c)  The Registration Statement conforms, and the Prospectus and any
further amendments or supplements to the Registration Statement or the
Prospectus will conform, in all material respects to the requirements of the Act
and the rules and regulations of the Commission thereunder and do not and will
not, as of the applicable effective date as to the Registration Statement and
any amendment thereto, and as of the applicable filing date as to the Prospectus
and any amendment or supplement thereto, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading; provided, however, that
this representation and warranty shall not apply to any statements or omissions
made in reliance upon and in conformity with information furnished in writing to
the Company by an Underwriter through Goldman, Sachs & Co. expressly for use
therein;

          (d)  Neither the Company nor any of its subsidiaries has sustained
since the date of the latest audited financial statements included in the
Prospectus any material loss or interference with its business from fire,
explosion, flood or other calamity, whether or not covered by insurance, or from
any labor dispute or court or governmental action, order or decree, otherwise
than as set forth or contemplated in the Prospectus; and, since the respective
dates as of which information is given in the Registration Statement and the
Prospectus, there has not been any change in the capital stock (other than
pursuant to the grant or exercise of options, or as a result of advances from
CMGI, Inc. (the "Parent") described in the Prospectus) or long-term debt of the
Company or any of its subsidiaries or any material adverse change, or any
development involving a prospective material adverse change, in or affecting the
general affairs, management, financial position, stockholders' equity or results
of operations of the Company and its subsidiaries, otherwise than as set forth
or contemplated in the Prospectus;

                                      -2-
<PAGE>

          (e)  The Company and its subsidiaries do not own any real property and
have good and marketable title to all personal property owned by them, free and
clear of all liens, encumbrances and defects except such as are described in the
Prospectus or such as do not materially affect the value of such property and do
not interfere with the use made and proposed to be made of such property by the
Company and its subsidiaries; and any real property and buildings held under
lease by the Company and its subsidiaries are held by them under valid,
subsisting and enforceable leases with such exceptions as are not material and
do not interfere with the use made and proposed to be made of such property and
buildings by the Company and its subsidiaries;

          (f)  The Company has been duly incorporated and is validly existing as
a corporation in good standing under the laws of the State of Delaware, with
power and authority (corporate and other) to own its properties and conduct its
business as described in the Prospectus, and has been duly qualified as a
foreign corporation for the transaction of business and is in good standing
under the laws of each other jurisdiction in which it owns or leases properties
or conducts any business so as to require such qualification, except where the
failure to be so qualified would not be reasonably likely to have a material
adverse effect on the business, financial condition, prospects or results of
operations of the Company and its subsidiaries, as a whole (a "Material Adverse
Effect); and each subsidiary of the Company has been duly incorporated and is
validly existing as a corporation in good standing under the laws of its
jurisdiction of incorporation;

          (g)  The Company has an authorized capitalization as set forth in the
Prospectus, and all of the issued shares of capital stock of the Company have
been duly and validly authorized and issued, are fully paid and non-assessable
and conform to the description of the Stock contained in the Prospectus; and all
of the issued shares of capital stock of each subsidiary of the Company have
been duly and validly authorized and issued, are fully paid and non-assessable
and (except for directors' qualifying shares [and except as set forth in the
Prospectus]) are owned directly or indirectly by the Company, free and clear of
all liens, encumbrances, equities or claims;

          (h)  The unissued Shares to be issued and sold by the Company to the
Underwriters hereunder have been duly and validly authorized and, when issued
and delivered against payment therefor as provided herein, will be duly and
validly issued and fully paid and non-assessable and will conform to the
description of the Stock contained in the Prospectus;

          (i)  The issue and sale of the Shares by the Company and the
compliance by the Company with all of the provisions of this Agreement and the
consummation of the transactions herein contemplated will not conflict with or
result in a breach or violation of any of the terms or provisions of, or
constitute a default under, any indenture, mortgage, deed of trust, loan
agreement or other agreement or instrument to which the Company or any of its
subsidiaries is a party or by which the Company or any of its subsidiaries is
bound or to which any of the property or assets of the Company or any of its
subsidiaries is subject, other than breaches or defaults that would not be
reasonably likely to have a Material Adverse Effect, nor will such action result
in any violation of the provisions of the Certificate of Incorporation or By-
laws of the Company or any statute or any order, rule or regulation of any court
or governmental agency or body having jurisdiction over the Company or any of
its subsidiaries or any of their properties; and no consent, approval,
authorization, order, registration or qualification of or with any such court or
governmental agency or body is required for the issue and sale of the Shares or
the consummation by the Company of the transactions contemplated by this
Agreement, except the registration under the Act of the Shares and such

                                      -3-
<PAGE>

consents, approvals, authorizations, registrations or qualifications as may be
required under state securities or Blue Sky laws in connection with the purchase
and distribution of the Shares by the Underwriters;

          (j)  Neither the Company nor any of its subsidiaries is (1) in
violation of its Certificate of Incorporation or By-laws or (2) in default in
the performance or observance of any obligation, agreement, covenant or
condition contained in any indenture, mortgage, deed of trust, loan agreement,
lease or other agreement or instrument to which it is a party or by which it or
any of its properties may be bound, except, in the case of clause (2), for such
defaults as are not reasonably likely to have a Material Adverse Effect;

          (k)  The statements set forth in the Prospectus under the caption
"Description of Capital Stock", insofar as they purport to constitute a summary
of the terms of the Stock and under the caption "Underwriting", insofar as they
purport to describe the provisions of the laws and documents referred to
therein, are accurate, complete and fair;

          (l)  Other than as set forth in the Prospectus, there are no legal or
governmental proceedings pending to which the Company or any of its subsidiaries
is a party or of which any property of the Company or any of its subsidiaries is
the subject which, if determined adversely to the Company or any of its
subsidiaries, would individually or in the aggregate be reasonably likely to
have a Material Adverse Effect; and, to the best of the Company's knowledge, no
such proceedings are threatened or contemplated by governmental authorities or
threatened by others;

          (m)  Other than as set forth in the Prospectus, the Company and its
subsidiaries own or have the right to use pursuant to license, sublicense,
agreement, or permission all patents, patent applications, trademarks, service
marks, trade names, copyrights, trade secrets, confidential information,

operation of the business of the Company and its subsidiaries as described in
the Prospectus and have taken all steps reasonably necessary to secure
assignments of such Intellectual Property from its employees and contractors; to
the knowledge of the Company none of the technology employed by the Company or

subsidiaries in violation of any contractual or fiduciary obligation binding on
the Company, its subsidiaries or any of their respective directors or executive
officers or, to the Company's knowledge, any of their respective employees or
consultants; and the Company and its subsidiaries have taken and will maintain
reasonable measures to prevent the unauthorized dissemination or publication of

have interfered with, infringed upon, misappropriated, or otherwise come into
conflict with any Intellectual Property rights of third parties, and the Company
and its subsidiaries have not received any charge, complaint, claim, demand, or
notice alleging any such interference, infringement, misappropriation, or
violation (including any claim that the Company or any of its subsidiaries must
license or refrain from using any intellectual property rights of any third
party) which, if the subject of any unfavorable decision, ruling or finding
would, individually or in the aggregate, be reasonably likely to have a Material
Adverse Effect;

     To the Company's knowledge, neither the Registration Statement nor the
Prospectus (A) contains any untrue statement of material fact with respect to
trademarks, trade names patents, mask works, copyrights, licenses, trade secrets
or other intellectual property rights owned by the Company or any of its
subsidiaries or (B) omits to state any material fact relating to trademarks,
trade names, patents, mask works, copyrights, licenses, trade secrets or other
intellectual property rights owned by the Company or any of its subsidiaries or
any allegation that is necessary to make the statement in the Registration
Statement or the Prospectus not misleading as to any such intellectual property
rights owned by the Company or any of its subsidiaries.

     To the Company's knowledge, there are no legal or governmental proceedings
pending relating to trademarks, trade names, patent rights, mask works, copy
rights, licenses, trade secrets or other intellectual property rights of the
Company or any of its subsidiaries other than the prosecution by the Company and
it subsidiaries of their patent applications before the United States Patent
Office and appropriate foreign government agencies, and no proceedings are
threatened or contemplated by governmental authorities or others relating to
trademarks, trade names, patent rights, mask works, copyrights, licenses or
other intellectual property rights of the Company or its subsidiaries.

          (n)  The Company is not and, after giving effect to the offering and

accountants as required by the Act and the rules and regulations of the
Commission thereunder; and

          (q)  The Company is in the process of reviewing its operations and
that of its subsidiaries and any third parties with which the Company or any of
its subsidiaries has a material relationship to evaluate the extent to which the
business or operations of the Company or any of its subsidiaries will be
affected by the Year 2000 Problem. As a result of such review, the Company has
no reason to believe, and does not believe, that the Year 2000 Problem will have
a Material Adverse Effect or result in any material loss or interference with
the Company's business or operations. The "Year 2000 Problem" as used herein
means any significant risk that computer hardware or software used in the
receipt, transmission, processing, manipulation, storage, retrieval,
retransmission or other utilization of data or in the operation of mechanical or

occurring after December 31, 1999, function at least as effectively as in the

               (iii)  The issue and sale of the Shares being delivered at such
     Time of Delivery by the Company and the compliance by the Company with all
     of the provisions of this Agreement and the consummation of the
     transactions herein contemplated will not conflict

                                      -12-

     with or result in a breach or violation of any of the terms or provisions
     of, or constitute a default under, any indenture, mortgage, deed of trust,
     loan agreement or other agreement or instrument known to such counsel to
     which the Company or any of its subsidiaries is a party or by which the
     Company or any of its subsidiaries is bound or to which any of the property
     or assets of the Company or any of its subsidiaries is subject, nor will
     such action result in any violation of the provisions of the Certificate of
     Incorporation or By-laws of the Company or any statute or any order, rule
     or regulation known to such counsel of any court or governmental agency or
     body having jurisdiction over the Company or any of its subsidiaries or any
     of their properties;

          (e)  On the date of the Prospectus at a time prior to the execution of
this Agreement, at 9:30 a.m., New York City time, on the effective date of any
post-effective amendment to the Registration Statement filed subsequent to the
date of this Agreement and also at each Time of Delivery, KPMG Peat Marwick LLP
shall have furnished to you a letter or letters, dated the respective dates of
delivery thereof, in form and substance satisfactory to you, to the effect set
forth in Annex I hereto (the executed copy of the letter delivered prior to the
execution of this Agreement is attached as Annex I(a) hereto and a draft of the
form of letter to be delivered on the effective date of any post-effective
amendment to the Registration Statement and as of each Time of Delivery is
attached as Annex I(b) hereto);

          (f)  (i)    Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included in
the Prospectus any loss or interference with its business from fire, explosion,
flood or other calamity, whether or not covered by insurance, or from any labor
dispute or court or governmental action, order or decree, otherwise than as set
forth or contemplated in the Prospectus, and (ii) since the respective dates as
of which information is given in the Prospectus there shall not have been any
change in the capital stock or long-term debt of the Company or any of its
subsidiaries or any change, or any development involving a prospective change,
in or affecting the general affairs, management, financial position,
stockholders' equity or results of operations of the Company and its
subsidiaries, otherwise than as set forth or contemplated in the Prospectus, the
effect of which, in any such case described in Clause (i) or (ii), is in the
judgment of the Representatives so material and adverse as to make it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Shares being delivered at such Time of Delivery on the terms and in the
manner contemplated in the Prospectus;

          (g)  On or after the date hereof (i) no downgrading shall have
occurred in the rating accorded the Company's debt securities by any "nationally
recognized statistical rating organization", as that term is defined by the
Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such
organization shall have publicly announced that it has under surveillance or
review, with possible negative implications, its rating of any of the Company's
debt securities;

          (h)  On or after the date hereof there shall not have occurred any of
the following: (i) a suspension or material limitation in trading in securities
generally on the New York Stock Exchange or on NASDAQ; (ii) a suspension or
material limitation in trading in the Company's securities on NASDAQ; (iii) a
general moratorium on commercial banking activities declared by either Federal
or New York or Massachusetts State authorities; or (iv) the outbreak or
escalation of hostilities involving the United States or the declaration by the
United States of a national emergency or war, if the effect of any such event
specified in this Clause (iv) in the judgment of the Representatives

                                      -13-
<PAGE>

makes it impracticable or inadvisable to proceed with the public offering or the
delivery of the Shares being delivered at such Time of Delivery on the terms and
in the manner contemplated in the Prospectus;

          (i)  The Shares to be sold at such Time of Delivery shall have been
duly listed for quotation on NASDAQ;

          (j)  The Company has obtained and delivered to the Underwriters
executed copies of an agreement from stockholders of the Company holding in
aggregate in excess of [95%] of the shares outstanding on the date of this
Agreement, substantially to the effect set forth in Subsection 5(e) hereof in
form and substance satisfactory to you;

          (k)  The Company shall have complied with the provisions of Section
5(c) hereof with respect to the furnishing of prospectuses on the New York
Business Day next succeeding the date of this Agreement; and

          (l)  The Company shall have furnished or caused to be furnished to you
at such Time of Delivery certificates of officers of the Company satisfactory to
you as to the accuracy of the representations and warranties of the Company
herein at and as of such Time of Delivery, as to the performance by the Company
of all of its obligations hereunder to be performed at or prior to such Time of
Delivery, as to the matters set forth in subsections (a) and (f) of this Section
and as to such other matters as you may reasonably request.

     8.   (a)  The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman, Sachs & Co. expressly for use therein.

          (b)  Each Underwriter will indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which the Company may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the

                                      -14-
<PAGE>

statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in any Preliminary Prospectus, the Registration
Statement or the Prospectus or any such amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by such
Underwriter through Goldman, Sachs & Co. expressly for use therein; and will
reimburse the Company for any legal or other expenses reasonably incurred by the
Company in connection with investigating or defending any such action or claim
as such expenses are incurred.

          (c)  Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of any indemnified party.

          (d)  If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Underwriters
on the other from the offering of the Shares. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law or if the indemnified party failed to give the notice required under
subsection (c) above, then each indemnifying party shall contribute to such
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company bear to the

                                      -15-
<PAGE>

total underwriting discounts and commissions received by the Underwriters, in
each case as set forth in the table on the cover page of the Prospectus. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or the Underwriters on the other and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Underwriters agree that
it would not be just and equitable if contributions pursuant to this subsection
(d) were determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to above in
this subsection (d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this subsection (d) shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (d), no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

          (e)  The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company (including any
person who, with his or her consent, is named in the Registration Statement as
about to become a director of the Company) and to each person, if any, who
controls the Company within the meaning of the Act.

     9.   (a)  If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within thirty-six hours
after such default by any Underwriter you do not arrange for the purchase of
such Shares, then the Company shall be entitled to a further period of thirty-
six hours within which to procure another party or other parties satisfactory to
you to purchase such Shares on such terms. In the event that, within the
respective prescribed periods, you notify the Company that you have so arranged
for the purchase of such Shares, or the Company notifies you that it has so
arranged for the purchase of such Shares, you or the Company shall have the
right to postpone such Time of Delivery for a period of not more than seven
days, in order to effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees to file promptly any amendments to the
Registration Statement or the Prospectus which in your opinion may thereby be
made necessary. The term "Underwriter" as used in this Agreement shall include
any person substituted under this

                                      -16-
<PAGE>

Section with like effect as if such person had originally been a party to this
Agreement with respect to such Shares.

          (b)  If, after giving effect to any arrangements for the purchase of
the Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased does not exceed one-eleventh of the aggregate number of all
the Shares to be purchased at such Time of Delivery, then the Company shall have
the right to require each non-defaulting Underwriter to purchase the number of
shares which such Underwriter agreed to purchase hereunder at such Time of
Delivery and, in addition, to require each non-defaulting Underwriter to
purchase its pro rata share (based on the number of Shares which such
Underwriter agreed to purchase hereunder) of the Shares of such defaulting
Underwriter or Underwriters for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

          (c)  If, after giving effect to any arrangements for the purchase of
the Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased exceeds one-eleventh of the aggregate number of all the
Shares to be purchased at such Time of Delivery, or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Shares of a defaulting Underwriter or Underwriters,
then this Agreement (or, with respect to the Second Time of Delivery, the
obligations of the Underwriters to purchase and of the Company to sell the
Optional Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company, except for the expenses to be borne
by the Company and the Underwriters as provided in Section 6 hereof and the
indemnity and contribution agreements in Section 8 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

          10.  The respective indemnities, agreements, representations,
warranties and other statements of the Company and the several Underwriters, as
set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of any Underwriter or any controlling person of any Underwriter, or the
Company, or any officer or director or controlling person of the Company, and
shall survive delivery of and payment for the Shares.

          11.  If this Agreement shall be terminated pursuant to Section 9
hereof, the Company shall not then be under any liability to any Underwriter
except as provided in Sections 6 and 8 hereof; but, if for any other reason, any
Shares are not delivered by or on behalf of the Company as provided herein, the
Company will reimburse the Underwriters through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Underwriters in making preparations for the
purchase, sale and delivery of the Shares not so delivered, but the Company
shall then be under no further liability to any Underwriter except as provided
in Sections 6 and 8 hereof.

          12.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement

                                      -17-
<PAGE>

on behalf of any Underwriter made or given by you jointly or by Goldman, Sachs &
Co. on behalf of you as the representatives.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 32 Old Slip, 9/th/ Floor, New York, New York 10005, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail to the
address of the Company set forth in the Registration Statement, Attention:
Secretary; provided, however, that any notice to an Underwriter pursuant to
Section 8(c) hereof shall be delivered or sent by mail, telex or facsimile
transmission to such Underwriter at its address set forth in its Underwriters'
Questionnaire, or telex constituting such Questionnaire, which address will be
supplied to the Company by you upon request.  Any such statements, requests,
notices or agreements shall take effect upon receipt thereof.

          13.  This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and, to the extent provided in
Sections 8 and 10 hereof, the officers and directors of the Company and each
person who controls the Company or any Underwriter, and their respective heirs,
executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement. No purchaser of
any of the Shares from any Underwriter shall be deemed a successor or assign by
reason merely of such purchase.

          14.  Time shall be of the essence of this Agreement. As used herein,
the term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

          15.  This Agreement shall be governed by and construed in accordance
with the laws of the State of New York.

          16.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

     Pursuant to Section 7(d) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

               (i)    They are independent certified public accountants with
respect to the Company and its subsidiaries within the meaning of the Act and
the applicable published rules and regulations thereunder;

               (ii)   In their opinion, the financial statements and any
supplementary financial information and schedules (and, if applicable, financial
forecasts and/or pro forma financial information) examined by them and included
in the Prospectus or the Registration Statement comply as to form in all
material respects with the applicable accounting requirements of the Act and the
related published rules and regulations thereunder; and, if applicable, they
have made a review in accordance with standards established by the American
Institute of Certified Public Accountants of the unaudited consolidated interim
financial statements, selected financial data, pro forma financial information,
financial forecasts and/or condensed financial statements derived from audited
financial statements of the Company for the periods specified in such letter, as
indicated in their reports thereon, copies of which have been furnished to the
representatives of the Underwriters (the "Representatives") and are attached
hereto;

               (iii)  They have made a review in accordance with standards
established by the American Institute of Certified Public Accountants of the
unaudited condensed consolidated statements of income, consolidated balance
sheets and consolidated statements of cash flows included in the Prospectus as
indicated in their reports thereon copies of which are attached hereto and on
the basis of specified procedures including inquiries of officials of the
Company who have responsibility for financial and accounting matters regarding
whether the unaudited condensed consolidated financial statements referred to in
paragraph (vi)(A)(i) below comply as to form in all material respects with the
applicable accounting requirements of the Act and the related published rules
and regulations, nothing came to their attention that cause them to believe that
the unaudited condensed consolidated financial statements do not comply as to
form in all material respects with the applicable accounting requirements of the
Act and the related published rules and regulations;

               (iv)   They have compared the information in the Prospectus under
selected captions with the disclosure requirements of Regulation S-K and on the
basis of limited procedures specified in such letter nothing came to their
attention as a result of the foregoing procedures that caused them to believe
that this information does not conform in all material respects with the
disclosure requirements of Items 301, 302, 402 and 503(d), respectively, of
Regulation S-K;

               (v)    On the basis of limited procedures, not constituting an
examination in accordance with generally accepted auditing standards, consisting
of a reading of the unaudited financial statements and other information
referred to below, a reading of the latest available interim financial
statements of the Company and its subsidiaries, inspection of the minute books
of the Company and its subsidiaries since the date of the latest audited
financial statements included in the Prospectus, inquiries of officials of the
Company and its subsidiaries responsible for financial and accounting matters
and such other inquiries and procedures as may be specified in such letter,
nothing came to their attention that caused them to believe that:

          (A)  (i)    the unaudited consolidated statements of income,
     consolidated balance sheets and consolidated statements of cash flows
     included in the Prospectus do not comply as to form in all material
     respects with the applicable accounting requirements of the Act and the
     related published rules and regulations, or (ii) any material modifications
     should be made to the unaudited condensed consolidated statements of
     income, consolidated balance sheets and consolidated statements of

                                      -21-
<PAGE>

     cash flows included in the Prospectus for them to be in conformity with
     generally accepted accounting principles;

          (B)  any other unaudited income statement data and balance sheet items
     included in the Prospectus do not agree with the corresponding items in the
     unaudited consolidated financial statements from which such data and items
     were derived, and any such unaudited data and items were not determined on
     a basis substantially consistent with the basis for the corresponding
     amounts in the audited consolidated financial statements included in the
     Prospectus;

          (C)  the unaudited financial statements which were not included in the
     Prospectus but from which were derived any unaudited condensed financial
     statements referred to in Clause (A) and any unaudited income statement
     data and balance sheet items included in the Prospectus and referred to in
     Clause (B) were not determined on a basis substantially consistent with the
     basis for the audited consolidated financial statements included in the
     Prospectus;

          (D)  any unaudited pro forma consolidated condensed financial
     statements included in the Prospectus do not comply as to form in all
     material respects with the applicable accounting requirements of the Act
     and the published rules and regulations thereunder or the pro forma
     adjustments have not been properly applied to the historical amounts in the
     compilation of those statements;

          (E)  as of a specified date not more than five days prior to the date

     RESOLVED:   That, pursuant to the authority expressly granted and vested in
                 the Board of Directors of this Corporation in accordance with
                 the provisions of its Amended and Restated Certificate of
                 Incorporation, a series of Preferred Stock of the Corporation
                 hereby is established, consisting of eight hundred thousand
                 (8000,000) shares, to be designated "Series A Convertible
                 Preferred Stock" (hereafter "Series A Preferred Stock"), the
                 Board of Directors be and hereby is authorized to issue such
                 shares of Series A Preferred Stock from time to time and for
                 such consideration and on such terms as the Board of Directors
                 shall determine; and subject to the limitations provided by law
                 and by the Corporation's Amended and Restate Certificate of
                 Incorporation, the powers, designations, preferences and
                 relative, participating, optional or other special rights,
                 powers or priorities of, and the qualifications, limitations or

                 follows:

     1.   Designation.  This series of Preferred Stock par value $0.01 per
          -----------

entitled to receive, out of funds legally available therefor, dividends computed
at a rate of 7% or $0.70 per share per annum (or a proportional part thereof for
a portion of a year and all subject to appropriate adjustment in the event of
any stock dividend, stock split, combination or other similar recapitalization
affecting such shares) commencing as of February 1, 1998, payable when, as and
if declared by the Board of Directors of the Corporation. The right to receive
dividends on Series A Preferred Stock shall be

<PAGE>

fact that no dividends have been declared on the Series A Preferred Stock in any
or every prior year.

          (b) The Corporation shall not declare or pay any distributions on
shares of Common Stock until the holders of shares of Series A Preferred Stock
then outstanding shall have first received a distribution at the rate specified
in paragraph (a) of this Section 2 calculated on a cumulative basis from the
date of issuance of said stock compounded annually as of any anniversary of the
date of issuance of such shares.

otherwise, "distribution" shall mean the transfer of cash or property without
consideration, whether by way of dividend or otherwise, payable other than in
Common Stock or other securities of the Corporation, or the purchase or
redemption of shares of the Corporation (other than repurchases of Common Stock
help by employees or directors of, or consultants to, the Corporation pursuant
to agreements providing for such repurchase and other than redemptions in
liquidation or dissolution of the Corporation) for cash or property, including
any such transfer, purchase or redemption by a subsidiary of the Corporation.

     3.   Liquidation, Dissolution or Winding Up.
          --------------------------------------

          (a) In the event of any liquidation, dissolution or winding up of the
Company, and provided that the amount available for distribution to holders of
the Series A Preferred Stock pursuant to this Section 3 is less than $10.00 per
share plus a dividend computed at a rate of 7% or $0.70 per share per annum,
compounded annually as of February 1, 1998 (such amount to be equitably adjusted
whenever there shall occur a stock split, combination, reclassification or other
similar event as provided in Section 5(e)(ii) hereof), whether voluntary or
involuntary, the entire assets of the Company available for such distribution
shall be distributed ratably among the holders of the Series A Preferred Stock.

          (b) In the event of any liquidation, dissolution or winding up of the
Company, and provided that the amount available for distribution to holders of
the Series A Preferred Stock pursuant to this Section 3 is at least $10.00 per
share plus a dividend computed at a rate of 7% or $0.70 per share per annum,
compounded annually as of February 1, 1998 (such amount to be equitably adjusted
whenever there shall occur a stock split, combination, reclassification or other
similar event as provided in Section 5(e)(ii) hereof), whether voluntary or
involuntary, holders of each share of Series A Preferred Stock shall be entitled
to be paid first out of the assets of the Company available for distribution to
holders of the Company's capital stock of all classes, whether such assets are
capital, surplus, or earnings, before any sums shall be paid or any assets
distributed among the holders of any other class of capital

                                     - 2 -
<PAGE>

stock, an amount equal to $10.00 per share of Series A Preferred Stock plus a
dividend computed at a rate of 7% or $0.70 per share per annum, compounded
annually as of February 1, 1998. After the payment of the preferential amount
required to be paid to the holders of the Series A Preferred Stock, upon the
liquidation, dissolution or winding up of the Corporation, the holders of shares
of the Corporation's Common Stock shall be entitled to receive the remaining
assets and funds of the Corporation available for distribution to its
stockholders.

          (c) A consolidation or merger of the Company or a sale of all or
substantially all of the assets of the Company shall be regarded as a
liquidation, dissolution or winding up of the affairs of the Company within the
meaning of this Section 3; provided, however, that each holder of Series A
Preferred Stock shall have the right to elect the benefits of the provisions of
Section 5(h) hereof in lieu of receiving payment in liquidation, dissolution or
winding up of the Company pursuant to this Section 3.  Each holder of Series A
Preferred Stock shall notify the Company in advance of its election to obtain
the benefits of this Section 3(c) or of Section 5(b), which notification shall
be given not later than a date specified in writing to each holder by the
Company to be at least five (5) days prior to the effective date of such
consolidation, merger or sale.  If a holder fails to make any election, he shall
be deemed to have elected the benefits of this Section 3(c).

          (d) Whenever the distribution provided for herein shall be paid in
property other than cash, the value of such distribution shall be the fair
market value of such property as determined in good faith by the Board of
Directors of the Company.

     4.   Voting Power. Except as otherwise expressly provided in Section 8
          ------------
hereof, or as required by law, each holder of Series A Preferred Stock shall be
entitled to vote on all matters and shall be entitled to that number of votes
equal to the largest number of whole shares of Common Stock into which such
holder's shares of Series A Preferred Stock could be converted, pursuant to the
provisions of Section 5 hereof (taking into account all accrued and unpaid
dividends, if any, with respect to such Series A Preferred Stock), at the record
date for the determination of shareholders entitled to vote on such matter or,
if no such record date is established, at the date such vote is taken or any
written consent of shareholders is solicited. Except as otherwise expressly
provided herein or as required by law, the holders of shares of Series A
Preferred Stock and of Common Stock shall be entitled to vote together as a
class on all matters.

     5.   Conversion Rights.  The holders of the Series A Preferred Stock shall
          -----------------
have the following conversion rights:

          (a) General.  Subject to and in compliance with the provisions of this
              -------
Section 5, any shares of the Series A Preferred Stock, may, at the option of the
holder,


                                     - 3 -
<PAGE>

be converted at any time or from time to time into fully-paid and non-
assessable shares (calculated as to each conversion to the largest whole share)
of Common Stock. The number of shares of Common Stock to which a holder of
Series A Preferred Stock shall be entitled upon conversion shall be the product
obtained by multiplying the Applicable Conversion Rate (determined as provided
in Section 5(c) by the number of shares of Series A Preferred Stock being
converted.  Upon conversion of their shares of Series A Preferred Stock into
shares of Common Stock, holders of shares of Series A Preferred Stock shall also
have the option to have all declared but unpaid dividends on such shares of
Series A Preferred Stock converted into shares of Common Stock.  the number of
shares of Common Stock to be received upon the conversion of such declared but
unpaid dividends shall be computed by multiplying the number of shares of Series
A Preferred Stock which could have been purchased with such declared but unpaid
dividends, assuming a Series A Preferred Stock purchase price of $10.00 per
share, by the Applicable Conversion Rate in effect at the time of such
conversion.

          (b) Conversion Following Underwritten Public Offering.
              -------------------------------------------------

          (i) All outstanding shares of Series A Preferred Stock shall, upon the
closing of an underwritten public offering pursuant to an effective registration
statement under the Securities Act of 1933, as amended, covering the offering
and sale of Common Stock for the account of the Company in which the Common
Stock is sold at a price to the public of not less than the amount per share
which would be equal to $10.00 per share plus a dividend computed at a rate of
7% or $0.70 per share per annum, compounded annually as of February 1, 1998
(such amount to be equitably adjusted whenever there shall occur a stock split,
combination, reclassification or other similar event affecting the Common Stock)
and in which the aggregate gross proceeds (before deduction of any underwriting
discounts, commissions or expenses) received by the Company from such public
offering, shall equal or exceed Fifteen Million Dollars ($15,0000,000), be
converted automatically into the number of shares of Common Stock to which a
holder of Series A Preferred Stock shall be entitled upon conversion pursuant to
Section 5(a) hereof without any further action by such holders and whether or
not the certificates representing such shares are surrendered to the Company or
its transfer agent for the Common Stock.

          (ii)  Upon the occurrence of the conversion specified in Section
5(b)(i), the holders of such Series A Preferred Stock shall surrender the
certificates representing such shares at the office of the Company or of its
transfer agent for the Common Stock.  Thereupon, there shall be issued and
delivered to each such holder a certificate or certificates for the number of
shares of Common Stock into which the shares of the Series A Preferred Stock
surrendered were convertible on the date on which such conversion occurred.  The
Company shall not be obligated to issue certificates evidencing the shares of
Common Stock issuable upon such

                                     - 4 -
<PAGE>

conversion unless certificates evidencing such shares of the Series A Preferred
Stock being converted are either delivered to the Company or any such transfer
agent or the holder notifies the Company or any such transfer agent that such
certificates have been lost, stolen or destroyed and executes an agreement
satisfactory to the Company to indemnify the Company from any loss incurred by
it in connection therewith. In addition, the Company may, if the Board of
Directors deems it reasonably necessary, require the holder to post a bond in
connection with such indemnity agreement.

          (c) Applicable Conversion Rate.  The conversion rate in effect at any
              --------------------------
time (the "Applicable Conversion Rate") shall be the quotient obtained by
dividing (i) $10.00 by (ii) the Applicable Conversion Value, calculated as
provided in Section 5(d).

          (d) Applicable Conversion Value.  The Applicable Conversion Value in
              ---------------------------
effect from time to time, except as adjusted in accordance with Section 5(e)
hereof, shall be $1.00 as of the date of this Certificate of Series A
Convertible Preferred Stock.

          (e) Adjustments to Applicable Conversion Value.
              ------------------------------------------

                  (i) Upon Sales of Common Stock. If the Company shall, while
                      --------------------------
there are any shares of Series A Preferred Stock outstanding, issue or sell
shares of its Common Stock without consideration or at a price per share less
than the Applicable Conversion Value in effect immediately prior to such
issuance or sale, then in each such case such Applicable Conversion Value upon
each such issuance or sale, except as hereinafter provided, shall be adjusted to
an amount determined by multiplying such Applicable Conversion Value by a
fraction:

                       (A) the numerator of which shall be (a) the number of
     shares of Common Stock outstanding immediately prior to the issuance of
     such additional shares of Common Stock, calculated on a fully diluted basis
     assuming exercise or conversion of all securities exercisable for or
     convertible into Common Stock, whether or not such exercise or conversion
     is unvested or otherwise conditional, plus (b) the number of shares of
     Common Stock which the net aggregate consideration received by the
     Corporation for the total number of such additional shares of Common Stock
     so issued would purchase at the Applicable conversion Value, and

                       (B) the denominator of which shall be (a) the number of
     shares of Common Stock outstanding immediately prior to the issuance of
     such additional shares of Common Stock, calculated on a fully diluted basis
     assuming exercise or

                                     - 5 -
<PAGE>

     conversion of all securities exercisable for or convertible into Common
     Stock, whether or not such exercise or conversion is unvested or otherwise
     conditional, plus (b) the number of such additional shares of Common Stock
     so issued or deemed issued.

The Corporation's issuance of up to an aggregate of two million (2,000,000)
shares of Common Stock (such amount to be equitably adjusted whenever there
shall occur a stock split, combination, reclassification or other similar event
affecting the Common Stock), or options exercisable therefor, pursuant to any
stock purchase or stock option plan or other individual or group incentive
program of any kind approved by the Board of Directors to the Corporation's
officers, directors, employees or consultants shall not be deemed an issuance of
additional shares of Common Stock and shall have no effect on the calculations
contemplated by this Section 5(e).

     For the purposes of this Section 5(e), the issuance of any warrants,
options, subscriptions or purchase rights with respect to shares of Common Stock
and the issuance of any securities convertible into or exchangeable for shares
of Common Stock (or the issuance of any warrants, options or any rights with
respect to such convertible or exchangeable securities) whether or not such
conversion or exchange is conditional, shall be deemed an issuance at such time
of such Common Stock if the Net Consideration Per Share (as hereinafter
determined) which may be received by the Company for such Common Stock shall be
less than the Applicable Conversion Value at the time of such issuance.  Any
obligation, agreement or undertaking to issue warrants, options, subscriptions
or purchase rights at any time in the future shall be deemed to be an issuance
at any time such obligation, agreement or undertaking is made or arises.  No
adjustment of the Applicable Conversion Value shall be made under this Section
5(e) upon the issuance of any shares of Common Stock which are issued pursuant
to the exercise of any warrants, options, subscriptions or purchase rights or
pursuant to the exercise of any conversion or exchange rights in any convertible
securities if any adjustment shall previously have been made upon the issuance
of any such warrants, options or subscriptions or purchase rights or upon the
issuance of any convertible securities (or upon the issuance of any warrants,
options or any rights therefor) as above provided.  Any adjustment of the
Applicable Conversion Value with respect to this paragraph which relates to
warrants, potions, subscriptions or purchase rights with respect to shares of
Common Stock shall be disregarded if, as, and when all of such warrants,
options, subscriptions or purchase rights expire or are cancelled without being
exercised, so that the Applicable Conversion Value effective immediately upon
such cancellation or expiration shall be equal to the Applicable Conversion
Value in effect at the time of the issuance of the expired or cancelled
warrants, options, subscriptions or purchase rights, with such additional
adjustments as would have been made to that Applicable Conversion Value had the
expired or cancelled warrants, options, subscriptions or purchase rights not
been issued.  For purposes of this paragraph, the "Net

                                     - 6 -
<PAGE>

Consideration Per Share" which may be received by the Company shall be
determined as follows:

                       (A) The "Net Consideration Per Share" shall mean the
     amount equal to the total amount of consideration, if any, received by the
     Company for the issuance of such warrants, options, subscriptions or other
     purchase rights or convertible or exchangeable securities, plus the minimum
     amount of consideration, if any, payable to the Company upon exercise,
     conversion or exchange thereof, divided by the aggregate number of shares
     of Common Stock that would be issued if all such warrants, options,
     subscriptions or other purchase rights or convertible or exchangeable
     securities were exercised, exchanged or converted.

                       (B) The "Net Consideration Per Share" which may be
     received by the Company shall be determined in each instance as of the date
     of issuance of warrants, options, subscriptions or other purchase rights or
     convertible or exchangeable securities without giving effect to any
     possible future price adjustments or rate adjustments which may be
     applicable with respect to such warrants, options, subscriptions or other
     purchase rights or convertible or exchangeable securities.

     For purposes of this Section 5(e), if a part or all of the consideration
received by the Company in connection with the issuance of shares of the Common
Stock or the issuance of any of the securities described in this Section 5(e)
consists of property other than cash, the Company at its expense will promptly
cause independent public accountants of recognized standing selected by the
Company to value such property, whereupon such value shall be given to such
consideration and shall be recorded on the books of the Company with respect to
receipt of such property.

     This Section 5(e)(i) shall not apply under any of the circumstances which
would constitute an Extraordinary Common Stock Event (as hereinafter defined in
Section 5(e)(ii)).

                  (ii)    Upon an Extraordinary Common Stock Event.  Upon the
                          ----------------------------------------
happening of an Extraordinary Common Stock Event (as hereinafter defined), the
Applicable Conversion Value shall, simultaneously with the happening of such
Extraordinary Common Stock Event, be adjusted by multiplying the then effective
Applicable Conversion Value by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such
Extraordinary Common Stock Event and the denominator of which shall be the

                                     - 7 -
<PAGE>

number of shares of Common Stock outstanding immediately after such
Extraordinary Common Stock event, and the product so obtained shall thereafter
be the Applicable Conversion Value.  The Applicable Conversion value, as so
adjusted, shall be readjusted in the same manner upon the happening of any
successive Extraordinary Common Stock Event or Events.

     "Extraordinary Common Stock Event" shall mean (i) the issue of additional
shares of Common Stock as a dividend or other distribution on outstanding shares
of Common Stock, (ii) the subdivision of outstanding shares of Common Stock into
a greater number of shares of Common Stock, or (iii) the combination of
outstanding shares of the Common Stock into a smaller number of shares of Common
Stock.

          (f) Dividends.  In the event the Company shall make or issue, or fix a
              ---------
record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in securities of the Company
other than shares of Common Stock or in assets (excluding cash dividends or
distributions), then and in each such event provisions shall be made so that the
holders of Series A Preferred Stock shall receive upon conversion thereof in
addition to the number of shares of Common Stock receivable thereupon, the
number of securities or such other assets of the Company which they would have
received had their Series A Preferred Stock been converted into Common Stock on
the date of such event and had they thereafter, during the period from the date
of such event to and including the Conversion Date (as that term is hereafter
defined in Section 5(j)), retained such securities or such other assets
receivable by them as aforesaid during such period, giving application to all
adjustments called for during such period under this Section 5 with respect to
the rights of the holders of the Series A Preferred Stock.

          (g) Recapitalization or Reclassification.  If the Common Stock
              ------------------------------------
issuable upon the conversion of the Series A Preferred Stock shall be changed
into the same or a different number of shares of any class or classes of stock
of the Corporation, whether by recapitalization, reclassification or otherwise
(other than a subdivision or combination of shares or stock dividend provided
for elsewhere in this Section 5, or a reorganization, merger, consolidation or
sale of assets provided for elsewhere in this Section 5), then and in each such
event the holder of each share of Series A Preferred Stock shall have the right
thereafter to convert such share into the kind and amount of shares of stock and
other securities and property receivable upon such reorganization,
reclassification or other change by holders of the number of shares of Common
Stock into which such share of Series A Preferred Stock might have been
converted (taking into account all accrued and unpaid dividends and interest
with respect to such Series A Preferred Stock) immediately prior to such
reorganization, reclassification or change, all subject to further adjustment as
provided herein.


                                     - 8 -
<PAGE>

          (h) Capitalization Reorganization, Merger or Sale of Assets.  If at
              -------------------------------------------------------
any time or from time to time there shall be a capital reorganization of the
Common Stock (other than a subdivision, combination, reclassification or
exchange of shares provided for elsewhere in this Section 5) or a merger or
consolidation of the Company with or into another corporation or entity, or the
sale of all or substantially all of the Company's properties and assets to any
other person or persons, then, as a part of such reorganization, merger,
consolidation or sale, provision shall be made so that the holders of the Series
A Preferred Stock shall thereafter be entitled to receive upon conversion of the
Series A Preferred Stock, the number of shares of stock or other securities or
property of the Company, or of the successor corporation or entity resulting
from such merger, consolidation or sale, to which a holder of Common Stock
issuable upon conversion would have been entitled on such capital
reorganization, merger, consolidation, or sale.  In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 5
with respect to the rights of the holders of the Series A Preferred Stock after
the reorganization, merger, consolidation or sale to the end that the provisions
of this Section 5 (including adjustment of the Applicable Conversion Value then
in effect and the number of shares purchasable upon conversion of the Series A
Preferred Stock) shall be applicable after that event in as nearly equivalent a
manner as may be practicable.

     Each holder of Series A Preferred Stock upon the occurrence of a capital
reorganization, merger or consolidation of the Company, or the sale of all or
substantially all its assets and properties as such events are more fully set
forth in the first paragraph of this Section 5(h), shall have the option of
electing treatment of his shares of Series A Preferred Stock under either this
Section 5(h) or Section 3(b) hereof, notice of which election shall be submitted
in writing to the Company at its principal offices no later than five (5) days
before the effective date of such event.

          (i) Accountant's Certificate as to Adjustments.  In each case of an
              ------------------------------------------
adjustment or readjustment of the Applicable Conversion Rate, the Company will
furnish each holder of Series A Preferred Stock with a certificate, prepared by
its chief financial officer showing such adjustment or readjustment, and stating
in detail the facts upon which such adjustment or readjustment is based.  Upon
the request of any holder, the Company will cause its independent public
accountants to confirm the accuracy of such adjustment or readjustment.

          (j) Exercise of Conversion Privilege.  To exercise his conversion
              --------------------------------
privilege, a holder of Series A Preferred Stock shall surrender the certificate
or certificates representing the shares being converted to the Company at its
principal office, and shall give written notice to the Company at that office
that such holder elects to convert such shares.  Such notice shall also state
the name or names (with address or addresses) in which the certificate or
certificates for shares of Common Stock issuable upon such conversion shall be
issued.  The certificate or certificates for

                                     - 9 -
<PAGE>

shares of Series A Preferred Stock surrendered for conversion shall be
accompanied by proper assignment thereof to the Company or in blank. The date
when such written notice is received by the Company, together with the
certificate or certificates representing the shares of Series A Preferred Stock
being converted, shall be the "Conversion Date." As promptly as practicable
after the conversion Date, the Company shall issue and shall deliver to the
holder of the shares of Series A Preferred Stock being converted, or on its
written order, such certificate or certificates as it may request for the number
of whole shares of Common Stock issuable upon the conversion of such shares of
Series A Preferred Stock in accordance with the provisions of this Section 5,
cash in the amount of all unpaid dividends on such shares of Series A Preferred
Stock, up to and including the Conversion Date, unless conversion of such unpaid
dividends into Common Stock has been elected, and cash, as provided in Section
5(k), in respect of any fraction of a share of Common Stock issuable upon such
conversion. Such conversion shall be deemed to have been effected immediately
prior to the close of business on the Conversion Date, and at such time the
rights of the holder as holder of the converted shares of Series A Preferred
Stock shall cease and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock shall be issuable upon
such conversion shall be deemed to have become the holder or holders of record
of the shares of Common Stock represented thereby.

          (k) Cash in Lieu of Fractional Shares.  No fractional shares of Common
              ---------------------------------
Stock or scrip representing fractional shares shall be issued upon the
conversion of shares of Series A Preferred Stock.  Instead of any fractional
shares of Common Stock which would otherwise be issuable upon conversion of
Series A Preferred Stock, the Company shall pay to the holder of the shares of
Series A Preferred Stock which were converted a cash adjustment in respect of
such fractional shares in an amount equal to the same fraction of the market
price per share of the Common Stock (as determined in a reasonable manner
prescribed by the Board of Directors) at the close of business on the Conversion
Date.  The determination as to whether or not any fractional shares are issuable
shall be based upon the total number of shares of Series A Preferred Stock being
converted at any one time by any holder thereof, not upon each share of Series A
Preferred Stock being converted.

          (l) Partial Conversion.  In the event some but not all of the shares
              ------------------
of Series A Preferred Stock represented by a certificate or certificates
surrendered by a holder are converted, the Company shall execute and deliver to
or on the order of the holder, at the expense of the Company, a new certificate
representing the number of shares of Series A Preferred Stock which were not
converted.

          (m) Reservation of Common Stock.  The Company shall at all times
              ---------------------------
reserve and keep available out of its authorized but unissued shares of Common
Stock, solely for the purpose of effecting the conversion of the shares of the
Series A Preferred Stock, such number of its shares of Common Stock as shall
from time to

                                    - 10 -
<PAGE>

time be sufficient to effect the conversion of all outstanding shares of the
Series A Preferred Stock and all unpaid dividends thereon, and if at any time
the number of authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of all then outstanding shares of the Series
A Preferred Stock and all unpaid dividends thereon, the Company shall take such
corporate action as may be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purpose.

     6.   Redemption.
          ----------

          (a) At the written election of a majority in interest of the holders
of Series A Preferred Stock on or before March 1, 2005, beginning on August 1,
2005 and on the first day of July in each year thereafter (the "Redemption
Date"), the Company shall redeem twenty-five percent (25%) of all of the
outstanding shares of Series A Preferred Stock; provided, however, that the
Company's redemption option shall be reduced by the number of shares of Series A
Preferred Stock that have been converted prior to any such Redemption Date, and
such reduction shall apply first to the Redemption Date immediately following
such conversion and thereafter any balance shall apply to any Subsequent
Redemption Dates.  The redemption price for each share of Series A Preferred
Stock redeemed pursuant to this Section 6 shall be $10.00 per share plus a
dividend computed at a rate of 7% or $0.70 per share per annum, compounded
annually as of February 1, 1998 (the "Redemption Price").  Each redemption of
Series A Preferred Stock shall be made so that the number of shares of Series A
Preferred Stock held by each holder whose shares are being redeemed shall be
reduced in an amount which shall bear the same ratio to the total number of
shares of Series A Preferred Stock being redeemed as all such shares then held
by such registered owner bears to the aggregate number of shares of Series A
Preferred Stock then outstanding and held by all registered owners whose shares
are being redeemed.

          (b) The Redemption Price set forth in this Section 6 shall be subject
to equitable adjustment whenever there shall occur a stock split, combination,
reclassification or other similar event involving the Series A Preferred Stock.

          (c) At least thirty (30) days before any Redemption Date pursuant to
Section 6(a), written notice (hereinafter referred to as the "Redemption
Notice") shall be mailed, postage prepaid, to each holder of record of the
Series A Preferred Stock which is to be redeemed, at its address shown on the
records of the Company; provided, however, that the giving of such Redemption
Notice shall not affect the conversion rights of such holder pursuant to Section
5 hereof; provided, further, that the Company's failure to give such Redemption
Notice shall in no way affect its obligation to redeem the shares of Series A
Preferred Stock as provided in Section 6(a) hereof.  The Redemption Notice shall
contain the following information:

                                    - 11 -
<PAGE>

                  (i) The number of shares of Series A Preferred Stock held by
the holder which shall be redeemed by the Company and the total number of shares
of Series A Preferred Stock held by all holders to be so redeemed,

                  (ii) The Redemption Date and the applicable Redemption Price,
and

                  (iii) That the holder is to surrender to the Company, at the
place designated therein, its certificate or certificates representing the
shares of Series A Preferred Stock to be redeemed.

          (d) Each holder of shares of Series A Preferred Stock to be redeemed
shall surrender the certificate or certificates representing such shares to the
Company at the place designated in the Redemption Notice, and thereupon the
applicable Redemption Price for such shares as set forth in this Section 6 shall
be paid to the order of the person whose name appears on such certificate or
certificates and each surrendered certificate shall be cancelled and retired.

          (e) If any shares of Series A Preferred Stock are not redeemed solely
because a holder fails to surrender the certificate or certificates representing
such shares pursuant to Section 6(d) hereof, then, from and after the Redemption
Date, such shares of Series A Preferred Stock thereupon subject to redemption
shall not be entitled to any further accrual of any dividends pursuant to
Section 2 hereof or to the conversion provisions set forth in Section 5 hereof,
unless the company otherwise specifically agrees in writing.

     7.   No Reissuance of Series A Preferred Stock.  No share or shares of
          -----------------------------------------
Series A Preferred Stock acquired by the Company by reason of redemption,
purchase, conversion or otherwise shall be reissued, and all such shares shall
be cancelled, retired and eliminated from the shares which the Company shall be
authorized to issue.  The Company may from time to time take such appropriate
corporate action as may be necessary to reduce the authorized number of shares
of the Series A Preferred Stock accordingly.

     8.   Restrictions and Limitations.
          ----------------------------

          (a) Except as expressly provided herein or as required by law, neither
the Company nor any subsidiary of the Company (which shall mean any corporation
or trust of which the Company directly or indirectly owns at the time all of the
outstanding shares of every class of such corporation or trust other than
directors' qualifying shares) shall, without the vote or written consent by the
holders of at least a majority of the then outstanding shares of the Series A
Preferred Stock voting together, each share of Series A Preferred Stock to be
entitled to one vote in each instance for each share of Common Stock into which
such Preferred Stock is then convertible:

                  (i) Redeem, purchase or otherwise acquire for value or (pay
in, to or set aside for a sinking fund for such purpose), any share or shares of
Series A Preferred Sock other than pursuant to the redemption provisions
contained elsewhere herein;

                  (ii) Authorize or issue, or obligate itself to authorize or
issue, any other equity security senior to or on a parity with the Series A
Preferred Stock as to liquidation preferences, conversion rights, redemption
rights, dividend rights, voting rights or otherwise;

                  (iii)  Effect any sale, lease, assignment, transfer or other
conveyance of all or substantially all of the assets of the Company or any

                  (iv) Effect any bank borrowings in excess of an aggregate
amount of Two Hundred Fifty Thousand Dollars ($250,000) U.S.;

                  (v) Effect any merger by the Company with or into any business
entity or any acquisition by the Company of any assets or business having a fair
market value in excess of One Million Dollars ($1,000,000) U.S.; or

                  (vi) Amend its Amended and Restated Certificate of
Incorporation, if such amendment would change any of the rights, preferences,
privileges of or limitations provided for herein for the benefit of any shares
of Series A Preferred Stock.

     9.   No Dilution or Impairment.  Except as provided in Section 8 above, the
          -------------------------
Company will not, by amendment of its Amended and Restated Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of the
Series A Preferred Stock set forth herein, but will at all times in good faith
assist in the carrying out of all such terms and in the taking of all such
actions as may be necessary or appropriate in order to protect the rights of the
holders of the Series A Preferred Stock against dilution or other impairment.
Without limiting the generality of the foregoing, the Company (a) will not
increase the par value of any shares of stock receivable on the conversion of
the Series A Preferred Stock above the amount payable therefor on such
conversion, (b) will take all such action as may be necessary or appropriate in
order that the Company may validly and legally issue fully paid

Stock from time to time outstanding and all accrued and unpaid dividends
thereon, and (c) will not transfer all or substantially all of its properties
and assets to any other person (corporate or otherwise), or consolidate with or
merge into any other person or permit any such person to consolidate with or
merge into the Company (if the Company is not the surviving person), unless such
other person shall expressly assume in writing and will be bound by all the
terms of the Series A Preferred Stock set forth herein.

     10.  Notices of Record Date.  In the event of
          ----------------------

          (a) any taking by the Company of a record of the holders of any class
of securities for the purpose of determining the holders thereof who are

          (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of Series A
Preferred Stock then outstanding shall be entitled to be paid out of the assets
of the Corporation available for distribution to its stockholders, after and
subject to the payment in full of all amounts required to be distributed to the
holders of any other class or series of stock of the Corporation ranking on
liquidation prior and in preference to the Series A Preferred Stock, but before
any payment shall be made to the holders of Series B Preferred Stock, Common
Stock or any other class or series of stock ranking on liquidation junior to the
Series A Preferred Stock, by reason of their
<PAGE>

ownership thereof, an amount equal to $10.00 per share (subject to appropriate
adjustment in the event of any stock dividend, stock split, combination or other
similar recapitalization affecting such shares), plus any accrued but unpaid
dividends with respect thereto. If upon any such liquidation, dissolution or
winding up of the Corporation, the remaining assets of the Corporation available
for distribution to its stockholders shall be insufficient to pay the holders of
shares of Series A Preferred Stock the full amount to which they shall be
entitled, the holders of shares of Series A Preferred Stock and any class or
series of stock ranking on liquidation on a parity with the Series A Preferred
Stock shall share ratably in any distribution of the remaining assets and funds
of the Corporation in proportion to the respective amounts which would otherwise
be payable in respect of the shares held by them upon such distribution if all
amounts payable on or with respect to such shares were paid in full.

          (b) After the payment of all preferential amounts required to be paid
to the holders of Series A Preferred Stock and any other class or series of
stock of the Corporation ranking on liquidation senior to the Series B Preferred
Stock, but before any payment shall be made to the holders of Common Stock or
any other class or series of stock ranking on liquidation junior to the Series B
Preferred Stock upon the liquidation, dissolution or winding up of the
Corporation, the holders of shares of Series B Preferred Stock then outstanding
shall be entitled to be paid out of the assets of the Corporation available for
distribution to its stockholders, by reason of their ownership thereof, an
amount equal to $8.3823 per share (subject to appropriate adjustment in the
event of any stock dividend, stock split, combination or other similar
recapitalization affecting such shares).  If upon any such liquidation,
dissolution or winding up of the Corporation, the remaining assets of the
Corporation available for distribution to its stockholders shall be insufficient
to pay the holders of shares of Series B Preferred Stock the full amount to
which they shall be entitled, the holders of shares of Series B Preferred Stock
and any class or series of stock ranking on liquidation on a parity with the
Series B Preferred Stock shall share ratably in any distribution of the
remaining assets and funds of the Corporation in proportion to the respective
amounts which would otherwise be payable in respect of the shares held by them
upon such distribution if all amounts payable on or with respect to such shares
were paid in full.

          (c) After the payment of all preferential amounts required to be paid
to the holders of Series A Preferred Stock, Series B Preferred Stock and any
other class or series of stock ranking on liquidation senior to the Common
Stock, upon the dissolution, liquidation or winding up of the Corporation, the
holders of shares of Common Stock then outstanding shall be entitled to receive,
on a pro-rata basis the remaining funds and assets of the Corporation available
for distribution to its stockholders.

          (d) With respect to the Series B Preferred Stock, a merger or
consolidation of the Corporation into or with another corporation in which the
holders of the outstanding capital stock of the Corporation immediately prior to
such
<PAGE>

merger or consolidation do not hold a majority of the outstanding capital
stock of the surviving corporation, or the sale of all or substantially all the
assets of the Corporation, shall be deemed to be a liquidation, dissolution or
winding up of the Corporation for purposes of this Section 2 unless the holder
of at least 51% of the then outstanding shares of Series B Preferred Stock elect
to have such events not deemed to be a liquidation, dissolution or winding up of
the Corporation by giving written notice thereof to the Corporation at least ten
(10) days before the effective date of such event.  If such notice is given, the
provisions of Subsection 4(h) below shall apply.  Whenever the distribution
provided for herein shall be paid in property other than cash, the value of such
distribution shall be the fair market value of such property as determined in
good faith by the Board of Directors of the Corporation.

     3.   Voting Power.  Except as otherwise expressly provided herein or as
          ------------
required by law, each holder of Series B Preferred Stock shall be entitled to
vote on all matters and shall be entitled to that number of votes equal to the
largest number of whole shares of Common Stock into which such holders shares of
Series B Preferred Stock could be converted, pursuant to the provisions of
Section 4 hereof (taking into account all declared but unpaid dividends, if any,
with respect to such Series B Preferred Stock), at the record date for the
determination of stockholders entitled to vote on such matter or, if no such
record date is established, at the date such vote is taken or any written
consent of stockholders is solicited.  Except as otherwise expressly provided
herein or as required by law, the holders of shares of Series A Preferred Stock,
Series B Preferred Stock and of Common Stock shall be entitled to vote together
as a class on all matters.

     4.   Conversion Rights.  The holders of the Series B Preferred Stock shall
          -----------------
have the following conversion rights:

          (a) General.  Subject to and in compliance with the provisions of this
              -------
Section 4, any shares of the Series B Preferred Stock, may, at the option of the
holder, be converted at any time or from time to time into fully-paid and non-
assessable shares (calculated as to each conversion to the largest whole share)
of Common Stock. The number of shares of Common Stock to which a holder of
Series B Preferred Stock shall be entitled upon conversion shall be the product
obtained by multiplying the Applicable Conversion Rate (determined as provided
in Section 4(c)) by the number of shares of Series B Preferred Stock being
converted.  Upon conversion of their shares of Series B Preferred Stock into
shares of Common Stock, holders of shares of Series B Preferred Stock shall also
have the option to have all declared but unpaid dividends on such shares of
Series B Preferred Stock converted into shares of Common Stock.  The number of
shares of Common Stock to be received upon the conversion of such declared but
unpaid dividends shall be computed by multiplying the number of shares of Series
B Preferred Stock which could have been purchased with such declared but unpaid
dividends, assuming a Series B Preferred Stock purchase price of $8.3823 per
share, by the Applicable Conversion Rate in effect at the time of such
conversion.
<PAGE>

          (b) Conversion Following Underwritten Public Offering.
              -------------------------------------------------

          (i) All outstanding shares of Series B Preferred Stock shall, upon the
closing of an underwritten public offering pursuant to an effective registration
statement under the Securities Act of 1933 as amended, covering the offering and
sale of Common Stock for the account of the Company in which the Common Stock is
sold at a price to the public of not less than the amount per share which would
be equal to $10.70 per share (such amount to be equitably adjusted whenever
there shall occur a stock split combination, reclassification or other similar
event affecting the Common Stock) and in which the aggregate gross proceeds
(before deduction of any underwriting discounts, commissions or expenses)
received by the Company from such public offering, shall equal or exceed Fifteen
Million Dollars ($15,000,000), be converted automatically into the number of
shares of Common Stock to which a holder of Series B Preferred Stock shall be
entitled upon conversion pursuant to Section 4(a) hereof without any further
action by such holders and whether or not the certificates representing such
shares are surrendered to the Company or its transfer agent for the Common
Stock.

          (ii)  Upon the occurrence of the conversion specified in Section
4(b)(i), the holders of such Series B Preferred Stock shall surrender the
certificates representing such shares at the office of the Company or of its
transfer agent for the Common Stock.  Thereupon, there shall be issued and
delivered to each such holder a certificate or certificates for the number of
shares of Common Stock into which the shares of the Series B Preferred Stock
surrendered were convertible on the date on which such conversion occurred.  The
Company shall not be obligated to issue certificates evidencing the shares of
Common Stock issuable upon such conversion unless certificates evidencing such
shares of the Series B Preferred Stock being converted are either delivered to
the Company or any such transfer agent or the holder notifies the Company or any
such transfer agent that such certificates have been lost, stolen or destroyed
and executes an agreement satisfactory to the Company to indemnify the Company
from any loss incurred by it in connection therewith.  In addition, the Company
may, if the Board of Directors deems it reasonably necessary, require the holder
to post a bond in connection with such indemnity agreement.

          (c) Applicable Conversion Rate.  The conversion rate in effect at any
              --------------------------
time (the "Applicable Conversion Rate") shall be the quotient obtained by
dividing (i) $8.3823 by (ii) the Applicable Conversion Value, calculated as
provided in Section 4(d).

          (d) Applicable Conversion Value.  The Applicable Conversion Value in
              ---------------------------
effect from time to time, except as adjusted in accordance with Section 4(e)
hereof, shall be $8.3823 as of the date of this Certificate of Series B
Convertible Preferred Stock.
<PAGE>

          (e) Adjustments to Applicable Conversion Value.
              ------------------------------------------

                  (i) Upon Sales of Common Stock. If the Company shall, while
                      --------------------------
there are any shares of Series B Preferred Stock outstanding, issue or sell
shares of its Common Stock without consideration or at a price per share less
than the Applicable Conversion Value in effect immediately prior to such
issuance or sale, then in each such case such Applicable Conversion Value upon
each such issuance or sale, except as hereinafter provided, shall be adjusted to
an amount equal to a fraction:

                       (A) the numerator of which shall be (a) the Applicable
     Conversion Value prior to the issuance multiplied by the number of shares
     of Common Stock outstanding immediately prior to the issuance of such
     additional shares of Common Stock, calculated on a fully diluted basis
     assuming exercise or conversion of all securities exercisable for or
     convertible into Common Stock, whether or not such exercise or conversion
     is unvested or otherwise conditional, plus (b) the price per share of such
     additional shares of Common Stock multiplied by number of such additional
     shares of Common Stock so issued or deemed issued, and

                       (B) the denominator of which shall be (a) the number of
     shares of Common Stock outstanding immediately prior to the issuance of
     such additional shares of Common Stock, calculated on a fully diluted basis
     assuming exercise or conversion of all securities exercisable for or
     convertible into Common Stock, whether or not such exercise or conversion
     is unvested or otherwise conditional, plus (b) the number of such
     additional shares of Common stock so issued or deemed issued.

The Corporation's issuance of shares of Common Stock, or options exercisable
therefor, pursuant to any stock purchase or stock option plan or other
individual or group incentive program of any kind approved by the Board of
Directors to the Corporation's officers, directors, employees or consultants
shall not be deemed an issuance of additional shares of Common Stock and shall
have no effect on the calculations contemplated by this Section 4(e).

     For the purposes of this Section 4(e), the issuance of any warrants,
options, subscriptions or purchase rights with respect to shares of Common Stock
and the issuance of any securities convertible into or exchangeable for shares
of Common Stock (or the issuance of any warrants, options or any rights with
respect to such convertible or exchangeable securities) whether or not such
conversion or exchange is conditional, shall be deemed an issuance at such time
of such Common Stock if the Net Consideration Per Share (as hereinafter
determined) which may be received by the Company for such Common Stock shall be
less than the Applicable Conversion
<PAGE>

Value at the time of such issuance. Any obligation, agreement or undertaking to
issue warrants, options, subscriptions or purchase rights at any time in the
future shall be deemed to be an issuance at any time such obligation, agreement
or undertaking is made or arises. No adjustment of the Applicable Conversion
Value shall be made under this Section 4(e) upon the issuance of any shares of
Common Stock which are issued pursuant to the exercise of any warrants, options
subscriptions or purchase rights or pursuant to the exercise of any conversion
or exchange rights in any convertible securities if any adjustment shall
previously have been made upon the issuance of any such warrants, options or
subscriptions or purchase rights or upon the issuance of any convertible
securities (or upon the issuance of any warrants, options or any rights
therefor) as above provided. Any adjustment of the Applicable Conversion Value
with respect to this paragraph which relates to warrants, options, subscriptions
or purchase rights with respect to shares of Common Stock shall be disregarded
if, as, and when all of such warrants, options, subscriptions or purchase rights
expire or are canceled without being exercised, so that the Applicable
Conversion Value effective immediately upon such cancellation or expiration
shall be equal to the Applicable Conversion Value in effect at the time of the
issuance of the expired or canceled warrants, options, subscriptions or purchase
rights, with such additional adjustments as would have been made to that
Applicable Conversion Value had the expired or canceled warrants, options,
subscriptions or purchase rights not been issued. For purposes of this
paragraph, the "Net Consideration Per Share" which may be received by the
Company shall be determined as follows:

                    (A) The "Net Consideration Per Share" shall mean the amount
               equal to the total amount of consideration, if any, received by
               the Company for the issuance of such warrants, options,
               subscriptions or other purchase rights or convertible or
               exchangeable securities, plus the minimum amount of
               consideration, if any, payable to the Company upon exercise,
               conversion or exchange thereof, divided by the aggregate number
               of shares of Common Stock that would be issued if all such
               warrants, options, subscriptions or other purchase rights or
               convertible or exchangeable securities were exercised, exchanged
               or converted.

                    (B) The "Net Consideration Per Share" which may be received
               by the Company shall be determined in each instance as of the
               date of issuance of warrants, options, subscriptions or other
               purchase rights or convertible or exchangeable securities without
               giving effect to any possible future price adjustments or rate
               adjustments which may be applicable with respect to such
               warrants, options, subscriptions or other purchase rights or
               convertible or exchangeable securities.
<PAGE>

     For purposes of this Section 4(e), if a part or all of the consideration
received by the Company in connection with the issuance of shares of the Common
Stock or the issuance of any of the securities described in this Section 4(e)
consists of property other than cash, the Company at its expense will promptly
cause independent public accountants of recognized standing selected by the
Company to value such property, whereupon such value shall be given to such
consideration and shall be recorded on the books of the Company with respect to
receipt of such property.

     This Section 4(e)(i) shall not apply under any of the circumstances which
would constitute an Extraordinary Common Stock Event (as hereinafter defined in
Section 4(e)(ii)).

                  (ii)  Upon an Extraordinary Common Stock Event.  Upon the
                        ----------------------------------------
happening of an Extraordinary Common Stock Event (as hereinafter defined), the
Applicable Conversion Value shall, simultaneously with the happening of such
Extraordinary Common Stock Event, be adjusted by multiplying the then effective
Applicable Conversion Value by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such
Extraordinary Common Stock Event and the denominator of which shall be the
number of shares of Common Stock outstanding immediately after such
Extraordinary Common Stock event, and the product so obtained shall thereafter
be the Applicable Conversion Value.  The Applicable Conversion Value, as so
adjusted, shall be readjusted in the same manner upon the happening of any
successive Extraordinary Common Stock Event or Events.

     "Extraordinary Common Stock Event" shall mean (i) the issue of additional
shares of Common Stock as a dividend or other distribution on outstanding shares
of Common Stock, (ii) the subdivision of outstanding shares of Common Stock into
a greater number of shares of Common Stock, or (iii) the combination of
outstanding shares of the Common Stock into a smaller number of shares of Common
Stock.

          (f) Dividends.  In the event the Company shall make or issue, or fix a
              ---------
record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in securities of the Company
other than shares of Common Stock or in assets (excluding cash dividends or
distributions), then and in each such event provisions shall be made so that the
holders of Series B Preferred Stock shall receive upon conversion thereof in
addition to the number of shares of Common Stock receivable thereupon the number
of securities or such other assets of the Company which they would have received
had their Series B Preferred Stock been converted into Common Stock on the date
of such event and had they thereafter, during the period from the date of such
event to and including the Conversion Date (as that term is hereafter defined in
Section 4(j)), retained such securities or such other assets receivable by them
as aforesaid during such period, giving application to all adjustments called
for during such period under this Section 4 with respect to the rights of the
holders of the Series B Preferred Stock.
<PAGE>

          (g) Recapitalization or Reclassification.  If the Common Stock
              ------------------------------------
issuable upon the conversion of the Series B Preferred Stock shall be changed
into the same or a different number of shares of any class or classes of stock
of the Corporation, whether by recapitalization, reclassification or otherwise
(other than a subdivision or combination of shares or stock dividend provided
for elsewhere in this Section 4, or a reorganization, merger, consolidation or
sale of assets provided for elsewhere in this Section 4), then and in each such
event the holder of each share of Series B Preferred Stock shall have the right
thereafter to convert such share into the kind and amount of shares of stock and
other securities and property receivable upon such reorganization,
reclassification or other change by holders of the number of shares of Common
Stock into which such share of Series B Preferred Stock might have been
converted (taking into account all declared and unpaid dividends and interest
with respect to such Series B Preferred Stock) immediately prior to such
reorganization, reclassification or change, all subject to further adjustment as
provided herein.

          (h) Capital Reorganization, Merger or Sale of Assets.  If at any time
              ------------------------------------------------
or from time to time there shall be a capital reorganization of the Common Stock
(other than a subdivision, combination, reclassification or exchange of shares
provided for elsewhere in this Section 4) or a merger or consolidation of the
Company with or into another corporation or entity, or the sale of all or
substantially all of the Company's properties and assets to any other person or
persons, then, as a part of such reorganization, merger, consolidation or sale,
provision shall be made so that the holders of the Series B Preferred Stock
shall thereafter be entitled to receive upon conversion of the Series B
Preferred Stock the number of shares of stock or other securities or property of
the Company, or of the successor corporation or entity resulting from such
merger, consolidation or sale, to which such holders would be entitled if they
were holders of the number of shares of Common Stock they were entitled to
receive on conversion of the Series B Preferred Stock held by them immediately
prior to such capital reorganization, merger consolidation, or sale.  In any
such case, appropriate adjustment shall be made in the application of the
provisions of this Section 4 with respect to the rights of the holders of the
Series B Preferred Stock after the reorganization, merger, consolidation or sale
to the end that the provisions of this Section 4 (including adjustment of the
Applicable Conversion Value then in effect and the number of shares purchasable
upon conversion of the Series B Preferred Stock) shall be applicable after that
event in as nearly equivalent a manner as may be practicable.

     Each holder of Series B Preferred Stock upon the occurrence of a capital
reorganization, merger or consolidation of the Company, or the sale of all or
substantially all its assets and properties as such events are more fully set
forth in the first paragraph of this Section 4(h), shall have the option of
electing treatment of his shares of Series B Preferred Stock under either this
Section 4(h) or Section 2(d) hereof, notice of which election shall be submitted
in writing to the Company at its principal offices no later than five (5) days
before the effective date of such event.
<PAGE>

          (i) Accountant's Certificate as to Adjustments.  In each case of an
              ------------------------------------------
adjustment or readjustment of the Applicable Conversion Rate, the Company will
furnish each holder of Series B Preferred Stock with a certificate, prepared by
its chief financial officer showing such adjustment or readjustment, and stating
in detail the facts upon which such adjustment or readjustment is based.  Upon
the request of any holder, the Company will cause its independent public
accountants to confirm the accuracy of such adjustment or readjustment.

          (j) Exercise of Conversion Privilege.  To exercise his conversion
              --------------------------------
privilege, a holder of Series B Preferred Stock shall surrender the certificate
or certificates representing the shares being converted to the Company at its
principal office, and shall give written notice to the Company at that office
that such holder elects to convert such shares.  Such notice shall also state
the name or names (with address or addresses) in which the certificate or
certificates for shares of Common Stock issuable upon such conversion shall be
issued.  The certificate or certificates for shares of Series B Preferred Stock
surrendered for conversion shall be accompanied by proper assignment thereof to
the Company or in blank.  The date when such written notice is received by the
Company, together with the certificate or certificates representing the shares
of Series B Preferred Stock being converted, shall be the "Conversion Date".  As
promptly as practicable after the Conversion Date, the Company shall issue and
shall deliver to the holder of the shares of Series B Preferred Stock being
converted, or on its written order, such certificate or certificates as it may
request for the number of whole shares of Common Stock issuable upon the
conversion of such shares of Series B Preferred Stock in accordance with the
provisions of this Section 4, cash in the amount of all unpaid dividends on such
shares of Series B Preferred Stock, up to and including the Conversion Date,
unless conversion of such unpaid dividends into Common Stock has been elected
and cash, as provided in Section 4(k), in respect of any fraction of a share of
Common Stock issuable upon such conversion.  Such conversion shall be deemed to
have been effected immediately prior to the close of business on the Conversion
Date, and at such time the rights of the holder as holder of the converted
shares of Series B Preferred Stock shall cease and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares of Common Stock represented thereby.

          (k) Cash in Lieu of Fractional Shares.  No fractional shares of Common
              ---------------------------------
Stock or scrip representing fractional shares shall be issued upon the
conversion of shares of Series B Preferred Stock.  Instead of any fractional
shares of Common Stock which would otherwise be issuable upon conversion of
Series B Preferred Stock, the Company shall pay to the holder of the shares of
Series B Preferred Stock which were converted a cash adjustment in respect of
such fractional shares in an amount equal to the same fraction of the market
price per share of the Common Stock (as determined in a reasonable manner
prescribed by the Board of Directors) at the close of business on the Conversion
Date.  The determination as to whether or not any fractional shares are issuable
shall be based upon the total
<PAGE>

number of shares of Series B preferred Stock being converted at any one time by
any holder thereof, not upon each share of Series B Preferred Stock being
converted.

          (l) Partial Conversion.  In the event some but not all of the shares
              ------------------
of Series B Preferred Stock represented by a certificate or certificates
surrendered by a holder are converted, the Company shall execute and deliver to
or on the order of the holder, at the expense of the Company, a new certificate
representing the number of shares of Series B Preferred Stock which were not
converted.

          (m) Reservation of Common Stock.  The Company shall at all times
              ---------------------------
reserve and keep available out of its authorized but unissued shares of Common
Stock, solely for the purpose of effecting the conversion of the shares of the
Series B Preferred Stock, such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all outstanding
shares of the Series B Preferred Stock and all unpaid dividends thereon, and if
at any time the number of authorized but unissued shares of Common Stock shall
not be sufficient to effect the conversion of all then outstanding shares of the
Series B Preferred Stock and all unpaid dividends thereon, the Company shall
take such corporate action as may be necessary to increase its authorized but
unissued shares of Common Stock to such number of shares as shall be sufficient
for such purpose.

     5.   No Reissuance of Series B Preferred Stock.  No share or shares of
          -----------------------------------------
Series B Preferred Stock acquired by the Company by reason of purchase or
conversion shall be reissued, and all such shares shall be canceled, retired and
eliminated from the shares which the Company shall be authorized to issue.  The
Company may from time to time take such appropriate corporate action as may be
necessary to reduce the authorized number of shares of the Series B Preferred
Stock accordingly; provided, that this provision shall not be construed to
permit the amendment of this Certificate of Designation with respect to any
matter other than the number of shares of Series B Stock authorized for
issuance, except with the consent of the holders of a majority in interest of
the issued and outstanding Series B Preferred Stock.

     6.   No Dilution or Impairment.  The Company will not, by amendment of its
          -------------------------
Amended and Restated Certificate of Incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of the Series B Preferred Stock set forth
herein, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such actions as may be necessary or
appropriate in order to protect the rights of the holders of the Series B
Preferred Stock against dilution or other impairment.  Without limiting the
generality of the foregoing, the Company (a) will not increase the par value of
any shares of stock receivable on the conversion of the Series B Preferred Stock
above the amount payable therefor on such conversion, (b) will take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and non-assessable shares of stock on the
conversion of all Series B Preferred Stock from time to time outstanding and all
accrued and unpaid
<PAGE>

dividends thereon, and (c) will not transfer all or substantially all of its
properties and assets to any other person (corporate or otherwise), or
consolidate with or merge into any other person or permit any such person to
consolidate with or merge into the Company (if the Company is not the surviving
person), unless such other person shall expressly assume in writing and will be
bound by all the terms of the Series B Preferred Stock set forth herein.

     7.   Notices of Record Date.  In the event of
          ----------------------

          (a) any taking by the Company of a record of the holders of any class
of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

          (b) any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company, any merger or
consolidation of the Company, or any transfer of all or substantially all of the
assets of the Company to any other corporation or any other entity or person, or

          (c) any voluntary or involuntary dissolution, liquidation or winding
up of the Company,

then and in each such event the Company shall mail or cause to be mailed to each
holder of Series B Preferred Stock a notice specifying (i) the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right and a description of such dividend, distribution or right, (ii) the date
on which any such reorganization, reclassification, recapitalization, transfer,
consolidation, merger, dissolution, liquidation or winding up is expected to
become effective, (iii) the time, if any, that is to be fixed, as to when the
holders of record of Common Stock (or other securities) shall be entitled to
exchange their shares of Common Stock (or other securities) for securities or
other property deliverable upon such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding up.  Such notice shall be mailed at least twenty (20) days prior to the
date specified in such notice on which such action is to be taken.

     This Certificate of Designation was duly adopted in accordance with the
applicable provisions of Section 151 of the Delaware General Corporation Law.

                                                                    ------------

                           ENGAGE TECHNOLOGIES, INC.

                       1999 EMPLOYEE STOCK PURCHASE PLAN

     The purpose of this Plan is to provide eligible employees of Engage
Technologies, Inc. (the "Company") and certain of its subsidiaries with
opportunities to purchase shares of the Company's common stock, $.01 par value
(the "Common Stock").  _______________ (______) shares of Common Stock (prior to
giving effect to the ____-for-____ stock split approved by the Company's Board
of Directors on ______, 1999) in the aggregate have been approved for this
purpose.  This Plan is intended to qualify as an "employee stock purchase plan"
as defined in Section 423 of the Internal Revenue Code of 1986, as amended (the
"Code"), and the regulations promulgated thereunder, and shall be interpreted
consistent therewith.

     1.   Administration.  The Plan will be administered by the Company's Board
          --------------
of Directors (the "Board") or by a Committee appointed by the Board (the
"Committee").  The Board or the Committee has authority to make rules and
regulations for the administration of the Plan and its interpretation and
decisions with regard thereto shall be final and conclusive.

     2.   Eligibility.  All employees of the Company, including Directors who
          -----------
are employees, and all employees of any subsidiary of the Company (as defined in
Section 424(f) of the Code) designated by the Board or the Committee from time
to time (a "Designated Subsidiary"), are eligible to participate in any one or
more of the offerings of Options (as defined in Section 9) to purchase Common
Stock under the Plan provided that:

          (a)  they are customarily employed by the Company or a Designated
     Subsidiary for more than 20 hours a week and for more than five months in a
     calendar year; and

          (b)  they have been employed by the Company or a Designated Subsidiary
     for at least six months prior to enrolling in the Plan; and

          (c)  they are employees of the Company or a Designated Subsidiary on
     the first day of the applicable Plan Period (as defined below).

     No employee may be granted an option hereunder if such employee,
immediately after the option is granted, owns 5% or more of the total combined
voting power or value of the stock of the Company or any subsidiary.  For
purposes of the preceding sentence, the attribution rules of Section 424(d) of
the Code shall apply in determining the stock ownership of an employee, and all
stock which the employee has a contractual right to purchase shall be treated as
stock owned by the employee.
<PAGE>

     3.   Offerings.  The Company will make one or more offerings ("Offerings")
          ---------
to employees to purchase stock under this Plan.  Unless otherwise determined by
the Board or Committee, the first Offering will commence on the effective date
of the Company's initial public offering of Common Stock (the "Effective Date")
and end on the last day of the first month following the end of the fiscal
quarter in which such Offering commences, provided that if upon the commencement
of such initial Offering there are less than 30 days remaining in such quarter,
such Offering shall end on the last day of the first month following the next
succeeding fiscal quarter. Unless otherwise determined by the Board or the
Committee, subsequent Offerings will commence on the date after the end of the
preceding Offering and will end on the last day of the third full month
thereafter.  Each such period is referred to as a Plan Period (a "Plan Period").
The Board or the Committee may, at its discretion, choose a different Plan
Period for any Offerings.

     4.   Participation.  An employee eligible on the first day of any Offering
          -------------
(an "Offering Commencement Date") may participate in such Offering by completing
and forwarding a payroll deduction authorization form to the employee's
appropriate payroll office at least seven (7) days prior to the applicable
Offering Commencement Date.  The form will authorize a regular payroll deduction
from the Compensation received by the employee during the Plan Period.  Unless
an employee files a new form or withdraws from the Plan, his or her deductions
and purchases will continue at the same rate for future Offerings under the Plan
as long as the Plan remains in effect.  The term "Compensation" means the amount
of money reportable on the employee's Federal Income Tax Withholding Statement,
excluding overtime, shift premium, incentive or bonus awards, allowances and
reimbursements for expenses such as relocation allowances for travel expenses,
income or gains on the exercise of Company stock options or stock appreciation
rights, and similar items, whether or not shown on the employee's Federal Income
Tax Withholding Statement, but including, in the case of salespersons, sales
commissions to the extent determined by the Board or the Committee.

     5.   Deductions.  The Company will maintain payroll deduction accounts for
          ----------
all participating employees.  With respect to any Offering made under this Plan,
an employee may authorize a payroll deduction in any whole percentage (not less
than 1% or more than 10%) or dollar amount not less than $10, or such lesser
amount as the Board or Committee shall determine before the start of each Plan
Period, of the Compensation he or she receives during the Plan Period or such
shorter period during which deductions from payroll are made, provided that such
                                                              --------
percentage or amount may not result in total deductions of less than $100 for
any Plan Period for any employee.

     No employee may be granted an Option (as defined in Section 9) which
permits his rights to purchase Common Stock under this Plan and any other

                                      -2-
<PAGE>

employee stock purchase plan (as defined in Section 423(b) of the Code) of the
Company and its subsidiaries, to accrue at a rate which exceeds $25,000 of the
fair market value of such Common Stock (determined at the Offering Commencement
Date of the Plan Period) for each calendar year in which the Option is
outstanding at any time.

     6.   Deduction Changes.  An employee may decrease, increase or discontinue
          -----------------
his payroll deduction once during any Plan Period, by filing a new payroll
deduction authorization form.  If an employee elects to discontinue his payroll
deductions during a Plan Period, but does not elect to withdraw his funds
pursuant to Section 8 hereof, funds deducted prior to his or her election to
discontinue will be applied to the purchase of Common Stock on the Exercise Date
(as defined below).

     7.   Interest.  Interest will not be paid on any employee accounts, except
          --------
to the extent that the Board or the Committee, in its sole discretion, elects to
credit employee accounts with interest at such per annum rate as it may from
time to time determine.

     8.   Withdrawal of Funds.  An employee may at any time prior to the close
          -------------------
of business on the last business day in a Plan Period and for any reason
permanently draw out the balance accumulated in the employee's account and
thereby withdraw from participation in an Offering.  Partial withdrawals are not
permitted.  The employee may not begin participation again during the remainder
of the Plan Period. The employee may participate in any subsequent Offering in
accordance with terms and conditions established by the Board or the Committee.

     9.   Purchase of Shares.  On the Offering Commencement Date of each Plan
          ------------------
Period, the Company will grant to each eligible employee who is then a
participant in the Plan an option ("Option") to purchase on the last business
day of such Plan Period (the "Exercise Date"), at the Option Price hereinafter
provided for, the largest number of whole shares of Common Stock of the Company
as does not exceed the number of shares determined by multiplying $1,667 by the
number of full months in the Offering Period and dividing the result by the
closing price (as defined below) on the Offering Commencement Date of such Plan
Period.

     The purchase price for each share purchased will be 85% of the closing
price of the Common Stock on (i) the first business day of such Plan Period or
(ii) the Exercise Date, whichever closing price shall be less.  Such closing
price shall be (a) the closing price on any national securities exchange on
which the Common Stock is listed, (b) the closing price on the Nasdaq National
Market or (c) the average of the closing bid and asked prices in the over-the-
counter-market, whichever is applicable, as published in The Wall Street
                                                         ---------------
Journal.  If no sales of Common Stock were made on such a day, the price of the
- -------
Common Stock for purposes of clauses (a) and (b) above shall be the reported
price for the next preceding day on which sales were made.

                                      -3-
<PAGE>

     Each employee who continues to be a participant in the Plan on the Exercise
Date shall be deemed to have exercised his or her Option at the Option Price on
such date and shall be deemed to have purchased from the Company the number of
full shares of Common Stock reserved for the purpose of the Plan that his
accumulated payroll deductions on such date will pay for, but not in excess of
the maximum number determined in the manner set forth above.

     Any balance remaining in an employee's payroll deduction account at the end
of a Plan Period, other than amounts that would have otherwise been applied for
the payment of fractional shares, will be automatically refunded to the
employee.

     10.  Issuance of Certificates.  Certificates representing shares of Common
          ------------------------
Stock purchased under the Plan may be issued only in the name of the employee,
in the name of the employee and another person of legal age as joint tenants
with rights of survivorship, or (in the Company's sole discretion) in the name
of a brokerage firm, bank or other nominee holder designated by the employee.
The Company may, in its sole discretion and in compliance with applicable laws,
authorize the use of book entry registration of shares in lieu of issuing stock
certificates.

     11.  Rights on Retirement, Death or Termination of Employment.  In the
          --------------------------------------------------------
event of a participating employee's termination of employment prior to the last
business day of a Plan Period, no payroll deduction shall be taken from any pay
due and owing to an employee and the balance in the employee's account shall be
paid to the employee or, in the event of the employee's death, (a) to a
beneficiary previously designated in a revocable notice signed by the employee
(with any spousal consent required under state law) or (b) in the absence of
such a designated beneficiary, to the executor or administrator of the
employee's estate or (c) if no such executor or administrator has been appointed
to the knowledge of the Company, to such other person(s) as the Company may, in
its discretion, designate.  If, prior to the last business day of the Plan
Period, the Designated Subsidiary by which an employee is employed shall cease
to be a subsidiary of the Company, or if the employee is transferred to a
subsidiary of the Company that is not a Designated Subsidiary, the employee
shall be deemed to have terminated employment for the purposes of this Plan.

     12.  Optionees Not Stockholders.  Neither the granting of an Option to an
          --------------------------
employee nor the deductions from his pay shall constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him or her.

     13.  Rights Not Transferable.  Rights under this Plan are not transferable
          -----------------------
by a participating employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.

                                      -4-
<PAGE>

     14.  Application of Funds.  All funds received or held by the Company under
          --------------------
this Plan may be combined with other corporate funds and may be used for any
corporate purpose.

     15.  Adjustment in Case of Changes Affecting Common Stock.  In the event of
          ----------------------------------------------------
a subdivision of outstanding shares of Common Stock, or the payment of a
dividend in Common Stock, the number of shares approved for this Plan, and the
share limitation set forth in Section 9, shall be increased proportionately, and
such other adjustment shall be made as may be deemed equitable by the Board or
the Committee.  In the event of any other change affecting the Common Stock,
such adjustment shall be made as may be deemed equitable by the Board or the
Committee to give proper effect to such event.

     16.  Merger.  In the event of a merger or consolidation of the Company with
          ------
or into another corporation, or of a sale of all or substantially all of the
assets of the Company, while unexercised Options remain outstanding under the
Plan, (a) subject to the provisions of clauses (b) and (c), after the effective
date of such transaction, each holder of an outstanding Option shall be
entitled, upon exercise of such Option, to receive in lieu of shares of Common
Stock, shares of such stock or other securities as the holders of shares of
Common Stock received pursuant to the terms of such transaction; or (b) all
outstanding Options may be cancelled by the Board or the Committee as of a date
prior to the effective date of any such transaction and all payroll deductions
shall be paid out to the participating employees; or (c) all outstanding Options
may be cancelled by the Board or the Committee as of the effective date of any
such transaction, provided that notice of such cancellation shall be given to
each holder of an Option, and each holder of an Option shall have the right to
exercise such Option in full based on payroll deductions then credited to his
account as of a date determined by the Board or the Committee, which date shall
not be less than ten (10) days preceding the effective date of such transaction.

     17.  Amendment of the Plan.  The Board may at any time, and from time to
          ---------------------
time, amend this Plan in any respect, except that (a) if the approval of any
such amendment by the shareholders of the Company is required by Section 423 of
the Code, such amendment shall not be effected without such approval, and (b) in
no event may any amendment be made which would cause the Plan to fail to comply
with Section 423 of the Code.

     18.  Insufficient Shares.  In the event that the total number of shares of
          -------------------
Common Stock specified in elections to be purchased under any Offering plus the
number of shares purchased under previous Offerings under this Plan exceeds the
maximum number of shares issuable under this Plan, the Board or the Committee
will allot the shares then available on a pro rata basis.

     19.  Termination of the Plan.  This Plan may be terminated at any time by
          -----------------------
the Board.  Upon termination of this Plan all amounts in the accounts of
participating employees shall be promptly refunded.

                                      -5-
<PAGE>

     20.  Governmental Regulations.  The Company's obligation to sell and
          ------------------------
deliver Common Stock under this Plan is subject to listing on a national stock
exchange or quotation on the Nasdaq National Market (to the extent the Common
Stock is then so listed or quoted) and the approval of all governmental
authorities required in connection with the authorization, issuance or sale of
such stock.

     21.  Governing Law.  The Plan shall be governed by Delaware law except to
          -------------
the extent that such law is preempted by federal law.

     22.  Issuance of Shares.  Shares may be issued upon exercise of an Option
          ------------------
from authorized but unissued Common Stock, from shares held in the treasury of
the Company, or from any other proper source.

     23.  Notification upon Sale of Shares.  Each employee agrees, by entering
          --------------------------------
the Plan, to promptly give the Company notice of any disposition of shares
purchased under the Plan where such disposition occurs within two years after
the date of grant of the Option pursuant to which such shares were purchased.

     24.  Effective Date and Approval of Shareholders.  The Plan shall take
          -------------------------------------------
effect on _____, 1999 subject to approval by the shareholders of the Company as
required by Section 423 of the Code, which approval must occur within twelve
months of the adoption of the Plan by the Board.

September 16, 1998

This letter agreement ("Agreement") will serve as a binding agreement between
Engage Technologies, Inc. ("Engage") on the one hand, and NaviSite Internet
Services Corporation ("NaviSite") and Servercast Communications, L.L.C.
("Servercast" collectively with NaviSite, "NaviSite/Servercast"), on the other
hand, concerning their respective responsibilities and the revenue sharing
arrangement between the parties for jointly providing the ad management service
solution to be called "AdBureau." This Agreement will remain in force until the
parties complete a definitive agreement ("Definitive Agreement") that more fully
describes terms of the arrangement between Engage and NaviSite/Servercast.

Engage will be responsible for providing the Accipiter AdManager software as
well as the sales, marketing, billing and end user support of Customers using
the AdBureau service.

NaviSite/Servercast will provide Internet connectivity, hardware, Oracle
databases and other relevant software. NaviSite/Servercast will additionally
market and sell AdBureau and bill directly the clients to whom it has sold
AdBureau.

The fees and revenue sharing for the AdBureau service will be as follows:

Fees:
- ----

 .    Set-up Fee:  [**] NaviSite/Servercast,  [**] Engage). (NaviSite and Engage
     will discuss guidelines to reduce set-up fees to close sale.)

 .    Engage will sell the AdBureau service at the mutually agreed CPM pricing
     levels. A schedule is attached. Changes in pricing will require
     NaviSite/Servercast's approval. AdBureau prices assume an average ad size
     of 10Kb. If a customer's monthly ads, on average, exceed 10Kb, the customer
     will incur an additional monthly fee.

Revenue sharing:
- ---------------

 .    If AdBureau is sold through Engage the revenue split will be
          NaviSite/ServerCast -[**] Engage -[**]
 .    If AdBureau is sold through NaviSite/ServerCast the revenue split will be

Terms and Mutual Exclusivity
- ----------------------------

The initial of the Definitive Agreement shall be three (3) years commencing as
of the Effective Date, unless terminated sooner for a material breach and other
customary early termination events. Engage agrees to partner exclusively with
NaviSite worldwide for the delivery of AdBureau for a three-year period,
beginning on the effective date of the Definitive Agreement. While this is a
worldwide exclusive, if NaviSite is unable to provide, or chooses not to
provide, services in certain foreign markets, Engage will be free to establish
relationships with other vendors to provide AdBureau services in those markets.

NaviSite, in turn, will not partner with competitive ad serving software
companies to resell their ad serving software as a service. However, NaviSite
will not be restricted from selling hosting services to customers for
competitive ad serving software. Additionally, NaviSite may sell competitive ad
serving software as a service if it is Engage-enable or it receives Engage's
prior approval.

The Definitive Agreement will include revenue and profitability targets to be
mutually agreed upon by the parties. There will be a review period every six (6)
months to evaluate if monthly revenues or profitability are below target, in
which case we will jointly re-architect the AdBureau service without affecting
current clients.

Upon the completion of the initial term, the Definitive shall automatically
renew for an additional one (1) year term, unless either party gives written
notice to terminate ninety (90) days prior to the expiration of the initial term
or any renewal term.

Additional provisions:
- ---------------------

 .    All contracts with customers will be signed with a 1-year minimum to
     ensure that any additional infrastructure incurred by NaviSite/ServerCast
     will be covered. Variations from the 1-year contract will require
     NaviSite/Servercast's approval.

 .    Engage will provide NaviSite/Sercast with the standard AdBureau contract
     for its review/approval. Variations from this standard contract will
     require approval by both parties to ensure mutual acceptability.

 .    NaviSite/Servercast will participate in testing all Beta versions of
     AdManager. It will roll out new version based on reasonable best efforts
     and reflecting the commercial viability of these new versions. Engage will
     make reasonable best efforts to develop these new versions of AdManager
     with the needs of NaviSite/Servercast and AdBureau customers in mind.

         Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission.  Asterisks denote omissions.

 .    Monthly minimum prices:
     Tier One (small customers with limited capital; ad serving size,[**]
     impressions per month). For these small customers Navisite/Servercast will
     not use Oracle.

There will be a cold back-up which means ad serving will be down for about 5 to
10 minutes (in the early am) daily. Fee: [**] monthly minimum with a set-up
charge of [**] upgrade to move to Oracle/Tier two. (To complete the sale, Engage
may drop the minimum charges to [**] monthly and [**] set up.)

Tier Two (customers with greater financial resources; ad serving volume, 1 ad on
up). For these customers NaviSite/Servercast will be using Oracle databases with
a hot back-up. Fee: [**] monthly minimum which corresponds to serving roughly
[**] ad impressions a month at the [**] CPM. (To complete the sale, Engage may
drop the minimum charges to [**] monthly and a [**] set-up.)

The parties hereby execute this Agreement by signing this letter in the space

hours to the records of Provider for purposes of audit of fees, if any, due and

Engage's reasonable request for Provider to make such inspection with respect to
a subdistributor.  Engage shall be provided a reasonable opportunity to
interview Provider's Subscribers and subdistributors and any employees who have
engaged in the marketing related to the Data Services in order to corroborate
the information contained in such records.  If any such audit reveals an
underpayment of more than 5% with respect to amounts due in any fiscal quarter
of Provider, Provider shall pay the cost of Engage's audit.

4.   Proprietary Rights.
     ------------------

     4.1  Ownership of Know How.  For purposes of this Agreement only, as
          ---------------------
between the parties, Engage and its suppliers have and shall retain all right,
title and interest in and to the Technology and Know How (subject to the
licenses granted herein), all copies, enhancements, improvements and Derivative
Works thereof (including revisions, updates, versions and releases), and all
other materials, including intellectual property rights therein whether existing
as of the Effective Date or created by Engage thereafter, subject to the rights
granted to Provider hereunder.  Provider shall retain all right, title and
interest (subject to the licenses granted herein) to technology and data created
by Provider.  In the event that Sumitomo Corporation or Provider (each an
"Inventing Party") creates a module or other functionality that

                                       7
<PAGE>

may function independently from the Know How, such Inventing Party shall, at the
request of Engage, grant Engage a worldwide, royalty-bearing, perpetual license
to use and commercialize such module or functionality (i) outside of the
Territory and (ii) inside the Territory upon the termination or expiration of
this Agreement, subject to mutual agreement between the Inventing Party and
Engage on the additional terms and conditions governing such license.

     4.2  Rights to Data.
          --------------

          4.2.1  Rights of Provider.  Provider and Engage shall agree on
                 ------------------
reasonable terms and conditions (including without limitation price) upon which
Provider shall be permitted to access and use, solely within the Territory, data
from Engage's proprietary data repository.  The price for such access and use
shall be a reasonable cost plus nominal margin.

          4.2.2  Rights of Engage.  Provider hereby grants to Engage a paid-up,
                 ----------------
royalty-free, worldwide, perpetual, irrevocable license to access, copy and use,
solely outside of the Territory, data from Provider's data repository.

5.   Trademark License.
     -----------------

     Engage hereby grants to Provider the right in the Territory during the term
of this Agreement to use the name "Engage.Knowledge" (the "Mark") only on or in
connection with the Data Services and Products and Provider's advertising for
the Data Services and Products, provided that Provider shall:  (i) only use the
Mark in the form and manner, and in accordance with the quality standards, that
Engage prescribes (and which it may change from time to time); (ii) at Engage's
request, submit samples of packaging and advertising to Engage for approval;
(iii) upon termination of this Agreement for any reason, immediately cease all
use of the Mark.  All goodwill associated with the Mark and Provider's use of
such Mark shall inure to Engage. Provider shall not contest the validity of,
use, register or attempt to register, or take other action with respect to any
name, logo, trademark, service mark, or other identifier used anywhere in the
world by Engage (or a mark confusingly similar thereto), except to the extent
authorized in writing by Engage in advance.  Provider's use of the Mark shall
clearly identify Engage as the owner of the Mark.  Provider shall immediately
notify Engage of any potential infringement of the Mark of which Provider
becomes aware.

6.   Confidentiality.
     ---------------

     6.1  Confidential Information.  The parties acknowledge and agree that
          ------------------------
during the course of performing their respective duties under this Agreement,
the parties may exchange confidential and proprietary information ("Confidential
Information"). Confidential Information shall include, without limitation, the
Know

                                       8
<PAGE>

How, the terms of this Agreement, customer lists, trade secrets, product plans
and schedules, new product information, technical data and know-how,
instructional and operating manuals, financial information, marketing and sales
data and plans, and other oral and written information. Each party acknowledges
that the Confidential Information of the other party constitutes valuable trade
secrets of that party. Each party agrees, therefore, to preserve the
confidential nature of the other party's Confidential Information by retaining
such Confidential Information in strict confidence and using such Confidential
Information only as required to perform hereunder. Each party agrees to promptly
report to the other party any violations of these provisions by its employees,
consultants, or agents of which they are aware. Except as expressly permitted
under this Agreement, neither party shall use, copy, make, modify, display or
transmit the Confidential Information, in whole or in part, or cause or permit
any third party to do so, without the prior written consent of the other party.
A party shall have no duty of confidentiality under this Section 6.1 with
respect to information the receiving party can document: (a) is or has become
readily publicly available without restriction through no fault of the receiving
party or its employees or agents; (b) is received without restriction from a
third party lawfully in possession of such information and lawfully empowered to
disclose such information; (c) was rightfully in possession of the receiving
party without restriction prior to its disclosure by the other party; (d) was
independently developed by the receiving party without access to such
Confidential Information; or (e) was required to be disclosed by a court or
other governmental authority after reasonable notice is given to the other
party.

     6.2  Equitable Relief.  If either party breaches any obligation with
          ----------------
respect to the use or confidentiality of the Confidential Information, the other
party shall be entitled to equitable relief to protect its interests therein,
including without limitation preliminary and permanent injunctive relief in
addition to any other remedies it may have.

7.   Term and Termination.
     --------------------

     7.1  Term.  This Agreement shall commence as of the Effective Date and,
          ----
unless sooner terminated as set forth in Section 7.2, continue indefinitely.

     7.2  Termination.
          -----------

          7.2.1  Termination for Cause.  Either party may, at its option,
                 ---------------------
terminate this Agreement if (i) the other party materially breaches a material
provision of this Agreement, (ii) such party gives the other party written
notice of such material breach (the "Default Notice") stating such party's
intention to terminate this Agreement, (iii) the other party fails to correct
such breach within thirty (30) days following its receipt of the Default Notice,
and (iv) such party gives the other party

                                       9
<PAGE>

written notice of termination of this Agreement, which termination will be
effective upon its receipt.

          7.2.2  Termination for Financial Distress.  In the event that either
                 ----------------------------------
party files a petition in bankruptcy, or has such a petition filed against it
that is not dismissed within thirty (30) days after filing, or is placed in a
receivership or reorganization proceeding or is placed in a trusteeship
involving an insolvency, or ceases doing business in the ordinary course, this
Agreement automatically shall terminate.

          7.2.3  Additional Termination Rights.  Engage may elect to terminate
                 -----------------------------
this Agreement immediately upon notice to Provider in the event that:  (i) the
Shareholders Agreement between Engage and Sumitomo Corporation of even date
herewith (the "Shareholders Agreement") is terminated for a reason not
attributable to Engage, or (ii) Provider is liquidated or dissolved for any
reason, in which case termination of this Agreement shall be effected
immediately prior to Provider's duly authorized decision to liquidate or
dissolve and otherwise in such a manner as to comply with applicable law and the
objective of this Section 7.2.3, or (iv) Sumitomo Corporation has not, on or
prior to August 31, 1998, satisfied the conditions of Sections 2.2 and 2.3 of
the Shareholders Agreement and consummated an equity investment in Engage of no
less than $1,500,000 due to a reason solely attributable to Sumitomo.

          7.2.4  Nonexclusive Remedy.  Termination is not an exclusive remedy
                 -------------------
and all other remedies will be available whether or not termination occurs.

8.   Effect of Termination.
     ---------------------

     8.1  Consequences.  Upon expiration or termination of this Agreement for
          ------------
any reason:  (i) all licenses and other rights granted to Provider under this
Agreement will become null and void; (ii) each party will return all tangible
embodiments of Confidential Information, catalogs and sales literature in its
possession or control, or at the other party's option, destroy such materials
and provide the other party with a certificate signed by an executive officer
attesting to the destruction thereof; and (iii) all outstanding obligations or
commitments of either party to pay amounts to the other party, if any, will
become immediately due and payable.  Each party understands that the rights of
termination hereunder are absolute.  Notwithstanding the foregoing, upon the
expiration or termination of this Agreement (but not in the event of termination
of this Agreement due to a breach by Provider), Provider may retain and use
internally, solely for purposes of providing maintenance and support services to
Subscribers, a copy of the Technology if Provider is contractually obligated, as
of the effective date of termination or expiration, to provide such services;
provided, however, that (a) the foregoing right shall terminate earlier of (i)
expiration of the last such Subscriber agreement and (ii) one (1) year from the
date of

                                       10
<PAGE>

such termination, and (b) Engage shall have no obligation to provide Provider or
its Subscribers with any maintenance or support services.

     8.2  No Separation Compensation.  Under no circumstances shall Engage be
          --------------------------
liable to Provider or any of its subdistributors by reason of termination,
expiration or nonrenewal of this Agreement for indemnification, compensation,
reimbursement, or damages for loss of prospective compensation, goodwill or loss
thereof, or expenditures, investments, leases, or any type of commitment made in
connection with the business of such party or in reliance on the existence of
this Agreement including, but not limited to advertising and promotion costs,
costs of supplies, termination of employees, employee salaries, and other such
costs and expenses.

9.   Indemnification.
     ---------------

     9.1  Indemnification of Provider.  Engage shall, at its expense, indemnify,
          ---------------------------
hold harmless and defend Provider from and against any and all damages, costs
and expenses, including reasonable attorneys' fees, incurred by Provider in
connection with a claim that the Technology, as delivered by Engage and used by
Provider within the scope of this Agreement, infringes any copyright, provided
that Provider notifies Engage promptly in writing of the infringement claim and
Engage has sole control over the defense or settlement of such claim and
Provider, at its expense, provides reasonable assistance in the defense of the
same.  Notwithstanding the foregoing, in the event that an infringement is found
and continued use of the Technology is enjoined, Engage will, at its option and
expense, either:  (i) procure for Provider the right to continue to use the
Technology; (ii) modify or alter the Technology so that it becomes non-
infringing; or (iii) replace the Technology with a non-infringing alternative.
If all of these options may only be exercised by Engage at an unreasonable cost,
then Engage may require Provider to immediately cease all use and distribution
of the Technology and terminate the Subscription Agreements under this Agreement
and pay to the Provider the Technology purchase fees that Provider paid to
Engage, less a portion for prior usage, amortized over a 3 year period.

     Engage shall have no obligation to indemnify Provider with respect to any
claim based upon (i) any modification of the Technology by a party other than
Engage; (ii) the combination, operation or use of the Technology with a non-
Engage software program or data if the claim would have been avoided had such
combination, operation or use not occurred; or (iii) the use of other than the
latest release of the Technology, if such claim could have been avoided by use
of the latest unmodified release.  Engage's obligation to indemnify Provider
will be reduced to the extent the damages could have been reduced by Provider's
use of the latest release.

     9.2  Indemnification of Engage.  Provider shall, at its expense, indemnify,
          -------------------------
hold harmless and defend Engage from, and against any and all damages, costs and
expenses including reasonable attorneys' fees, incurred by Engage in connection
with

                                       11
<PAGE>

any claim (i) against Engage by any Subscriber which relates to such
Subscriber's relationship with Provider or a subdistributor (and not to any
direct relationship which Engage may have with such Subscriber), (ii) arising
from the performance of the Data Services by Provider, or (iii) any
representation, promise, guarantee or warranty made or implied by Provider or a
subdistributor to the extent it exceeds or differs from those expressly set
forth in the documentation accompanying the Data Services EXCEPT as may be
attributed to Engage's failure to meet the representations, warranties,
covenants or other agreements herein or in the Shareholders Agreement:

10.  Warranty and Disclaimer.
     -----------------------

     10.1  Warranty of Authority.  Engage represents and warrants that it
           ---------------------
possesses the rights in the Know How to perform its obligations hereunder.  The
representations and warranties contained in Clauses 22.2 and 22.4 of the
Shareholders Agreement shall apply in relation to the Technology as if they were
set forth in full herein for the benefit of Provider.

     10.2  DISCLAIMER OF WARRANTIES.  EXCEPT AS SET FORTH HEREIN OR IN THE
           ------------------------
SHAREHOLDERS AGREEMENT, ENGAGE MAKES NO WARRANTIES OR REPRESENTATIONS TO
PROVIDER OR ANY OTHER PERSON AS TO THE TECHNOLOGY, SOFTWARE OR ANY SERVICES
RENDERED WITH THE TECHNOLOGY OR SOFTWARE.  ENGAGE DISCLAIMS ALL EXPRESS AND
IMPLIED WARRANTIES, ORAL OR WRITTEN, INCLUDING BUT NOT LIMITED TO, IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT
AND ANY WARRANTIES ARISING FROM COURSE OF DEALING, COURSE OF PERFORMANCE OR
USAGE OF THE TRADE.

     10.3  Acknowledgment.  Provider acknowledges that the Know How and
           --------------
Technology have not been prepared to meet the individual requirements of
Provider or its Subscribers.  It is the responsibility of Provider and its
Subscribers to ensure that the functions and facilities performed by the
Technology and Data Services meet the Subscriber's requirements.

11.  Limitation of Liability.
     -----------------------

     NOTWITHSTANDING ANYTHING ELSE IN THIS AGREEMENT OR OTHERWISE, NEITHER
ENGAGE NOR ITS AFFILIATES SHALL BE LIABLE OR OBLIGATED WITH RESPECT TO THE
SUBJECT MATTER OF THIS AGREEMENT OR UNDER ANY CONTRACT, NEGLIGENCE, STRICT
LIABILITY OR OTHER LEGAL OR EQUITABLE THEORY (I) FOR ANY AMOUNTS IN EXCESS IN
THE AGGREGATE OF THE FEES PAID TO IT HEREUNDER; OR (II) SPECIAL, CONSEQUENTIAL,
INCIDENTAL, RELIANCE, EXEMPLARY, OR INDIRECT DAMAGES (INCLUDING SUCH DAMAGES DUE
TO LOSS OF DATA, PROFITS,

                                       12

written consent of Engage (and any attempt to do so shall be null and void).
Subject to the limitations above, this Agreement will mutually benefit and be
binding upon the parties, their successors and assigns.

     13.2  Waiver.  No waiver of any portion of this Agreement shall be
           ------
effective unless in writing. The failure of a party at any time to require
performance by the other party of any provision shall in no way affect the right
of such party to enforce that or any other provision of this Agreement. No
waiver of any breach of this Agreement shall constitute a waiver of any
subsequent breach of the same or any other provision of this Agreement.

     13.3  Notices.  All notices given pursuant to this Agreement shall be in
           -------
writing sent prepaid by certified or registered mail or overnight express

service shall be effective as of the first business day following submission to
the overnight express delivery service.  All such notices shall be directed to
the respective parties at the addresses set forth on the first page of this
Agreement unless either party notifies the other in writing of a new address.

     13.4  Law and Jurisdiction.  This Agreement shall be governed and
           --------------------
interpreted in all respects by and according to the laws of the Commonwealth of
Massachusetts, U.S.A., excluding its choice of law provisions.  It is the

with the said rules. In the event that the arbitration is sought by Engage, the
arbitration shall be held in Tokyo, Japan. In the event that the arbitration is
sought by Provider, the arbitration shall be held in Boston, Massachusetts,
U.S.A. The arbitration shall be in the English language. Notwithstanding the
foregoing, each party shall have the right to institute judicial proceedings
against the other party or anyone acting by, through or under such other party
in order to enforce the instituting party's rights hereunder through reformation
of contract, specific performance, injunction or similar equitable relief.

to contribute to the Data Repository.

will at all times during the term of this Agreement establish, maintain and post
on each web site served by an Enterprise Server or Local Server a written policy
regarding the collection and use by Licensee of visitor information.

6.   RIGHT TO USE SOFTWARE

<PAGE>

license to install and operate only on Licensee's premises in the U.S. the
Software solely for Licensee's own internal use on one or more Enterprise or
Local Servers hosting the Domain Name(s).

     6.2  Restrictions.  Licensee may use the Software only for the purpose of
          ------------
subscribing and/or contributing to the Data Repository.  Without limiting the
foregoing, Licensee may not use the Software for the purpose of creating,
maintaining or operating an enterprise or any other data repository.  Except as
expressly provided herein, Licensee shall not, and shall not permit others to,
use, modify, copy (except for one Licensee back-up copy containing Engage's
copyright notices and other proprietary marks), distribute, sublicense, assign,
use for service bureau purposes, share, timeshare, rent or otherwise transfer,
or decompile, disassemble, reverse engineer or otherwise attempt to derive the
source code form of the Software, in whole or in part.  All rights not expressly
granted to Licensee are reserved by Engage.  There are no implied rights.

     6.3  Indemnification.  Engage, at its expense, shall defend any action,
          ---------------
suit or proceeding brought against Licensee which alleges that the Software
infringes any U.S. copyright and Engage shall pay damages finally awarded
against Licensee; provided that Licensee promptly notifies Engage of the action
and gives Engage the opportunity, sole authority, information and assistance (at
Engage's expense) for control of the defense and settlement of the action; but
Engage shall not be responsible for any legal costs incurred or settlement made
without notice and its consent.  Engage may, at its sole option and at its
expense, either:  (i) replace or modify the Software to make it non-infringing
without material impairment of its functionality; (ii) obtain for Licensee the
right to continue using the Software, or (iii) terminate this Agreement.  Engage
shall have no liability for any infringement or claim thereof based upon:  (a)
the combination of the Software with products not provided by Engage, or (b)
modification or alteration of the Software by any person or entity other than
Engage.  THIS SECTION STATES ENGAGE'S SOLE LIABILITY WITH RESPECT TO
INFRINGEMENT OF ANY INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS.

     6.4  Maintenance Services.  Subject to the terms and conditions of this
          --------------------
Agreement, Engage will provide Licensee with the Software maintenance services
set forth in Attachment 1 during the term of this Agreement.

          ------------
future, to Engage and its successors and assigns, all right, title and interest
in and to the Visitor Data, as well as all intellectual property rights therein.
From time to time upon the request of Engage or its successor or assign,
Contributor will make such further assignments and confirm such assignments by
execution and delivery of such assignments, confirmations of assignment, or
other written instruments as Engage may reasonably request in order to
effectuate this Section 7.2.

     7.3  Confidentiality.  Licensee acknowledges and agrees that (i) the Data,
          ---------------
Profiles, Documentation and the design, operational methods and coding of the
Software (collectively "Confidential Materials") are not generally known to, or
readily ascertainable by, the public, (ii) Engage uses all reasonable efforts on
a consistent basis to prevent the acquisition, disclosure or use of the
Confidential Materials without the specific consent of Engage, (iii) Engage
derives substantial economic value from the secrecy of the Confidential
Materials, and (iv) acquisition, disclosure or use, beyond the limited extent
permitted herein, of the Confidential Materials would cause significant damage
to Engage's business.  Accordingly, Licensee agrees to hold the Confidential
Materials in strict confidence and not to disclose the Confidential Materials to
any third party without the prior consent of Engage.

     7.4  Equitable Relief.  Licensee acknowledges that the unauthorized
          ----------------
disclosure or use of the Confidential Materials other than as expressly set
forth herein will (i) substantially diminish the value to Engage of the
Confidential Materials and (ii) cause irreparable injury in a short period of
time, and that Engage's remedy at law for such unauthorized disclosure or use is
inadequate.  Accordingly, if Licensee breaches any of its obligations with
respect to the confidentiality or use of the Confidential Materials, Engage will
be entitled to equitable relief to protect its interests therein, including, but
not limited to, preliminary and permanent injunctive relief, in addition to any
other remedies it may have, without the necessity of posting bond.

its End Users any maintenance or support services.  Reseller may elect to
purchase maintenance and support services from Engage pursuant to a separate
maintenance services agreement (the "Maintenance Services Agreement"); in such
event, Engage shall be responsible for providing such services only to Reseller

"Warranty Defects").  Reseller shall use its commercially reasonable best
efforts to resolve with End Users all user and operational errors. If problems
are attributable to defective media, Engage shall, as soon as practicable,
supply replacement Products at no cost to Reseller.  If Reseller believes that
user problems are due to Warranty Defects, it shall promptly report this fact to
Engage and Engage shall make its best endeavors to remedy such Warranty Defects
pursuant to Section 2.5.2 and Section 11.1.

warranted performance during the Warranty Period because of such Warranty

of any purchase order, confirmation, or similar form even if signed by the
parties after the Effective Date shall have no force or effect.  All orders are

provisions by its employees, consultants, or agents of which they are aware.
Except as expressly permitted under this Agreement, neither party shall use,
copy, make, modify, display or transmit the Confidential Information, in whole

written consent of the other party.  A party shall have no duty of
confidentiality under this Section 7 with respect to information the receiving
party can document: (a) is or has become readily publicly available without
restriction through no fault of the receiving party or its employees or agents;
(b) is received without restriction from a third party lawfully in possession of
such information and lawfully empowered to disclose such information; (c) was
rightfully in possession

<PAGE>

of the receiving party without restriction prior to its disclosure by the other
party; (d) was independently developed by the receiving party without access to

other governmental authority after reasonable notice is given to the other
party.

          ----------------

party shall be entitled to equitable relief to protect its interests therein,

addition to any other remedies it may have.

Shareholders Agreement relating to the Reseller between Engage and SC (the

                 ----------------------------------
party files a petition in bankruptcy, or has such a petition filed against it

Agreement automatically shall terminate.

          8.2.4  Additional Termination Rights.  Engage may elect to terminate

commitments of either party to pay amounts to the other party, if any, will
become immediately due and payable; and (iv) for any order of Products received
but not shipped at the time of termination, Engage shall have the option to
cancel the order or fulfill the order in the case of the Agreement being
terminated due to the reason attributable to Reseller.  Each party understands

foregoing, upon the expiration or termination of this Agreement (but not in the
event of termination of this Agreement due to a breach by Reseller), (a) if

for credit, and (b) Reseller may retain and use internally, solely for purposes
of providing maintenance and support services to End Users, a copy of each

have no obligation to provide Reseller or its End Users with any maintenance or
support services.

thereof, or expenditures,

                                       10
<PAGE>

investments, leases, or any type of commitment made in connection with the
business of such party or in reliance on the existence of this Agreement
including, but not limited to advertising and promotion costs, costs of
supplies, termination of employees, employee salaries, and other such costs and
expenses.

10.  Indemnification.
     ---------------

     10.1  Indemnification of Reseller.  Engage shall, at its expense,
           ---------------------------
indemnify, hold harmless and defend Reseller from and against any and all
damages, costs and expenses, including reasonable attorneys' fees, incurred by
Reseller in connection with (a) a claim that a Product, as delivered by Engage
and used by Reseller within the scope of this Agreement, infringes any
copyright, (b) a prohibition or restriction on Reseller's exercise of any right
granted in Section 2 hereof during the term of this Agreement other than those
prohibitions or restrictions set forth in this Agreement (or any other agreement
between the parties); provided that Reseller notifies Engage promptly in writing
of the infringement claim and Engage has sole control over the defense or
settlement of such claim and Reseller, at its expense, provides reasonable
assistance in the defense of the same. Notwithstanding the foregoing, in the
event that an infringement is found and continued use of a Product is enjoined,
Engage will, at its option and expense, either: (i) procure for Reseller the
right to continue to use the Product; (ii) modify or alter the Product so that
it becomes non-infringing; or (iii) replace the Product with a non-infringing
alternative. If all of these options may only be exercised by Engage at an
unreasonable cost, then Engage may require Reseller to immediately cease all use
and distribution of the Product and terminate the End User Licenses granted
under this Agreement and pay to the Reseller the Product purchase fees that
Reseller paid to Engage, less a portion for prior usage, amortized over a 3 year
period.

     Engage shall have no obligation to indemnify Reseller with respect to any
claim based upon (i) any modification of a Product by a party other than Engage;
(ii) the combination, operation or use of the Product with a non-Engage software
program or data if the claim would have been avoided had such combination,
operation or use not occurred; or (iii) the use of other than the latest release
of a Product, if such claim could have been avoided by use of the latest
unmodified release, which release is provided by Engage to Reseller pursuant to
the terms of the Maintenance Services Agreement.  Engage's obligation to
indemnify Reseller will be reduced to the extent the damages could have been
reduced by Reseller's use of the latest release.

     10.2  Indemnification of Engage.  Reseller shall, at its expense,
           -------------------------
indemnify, hold harmless and defend Engage from, and against any and all
damages, costs and expenses including reasonable attorneys' fees, incurred by
Engage in connection with any claim (i) against Engage by an End User which
relates to such End User's relationship with Reseller or a subdistributor (and
not to any direct relationship which Engage may have with such End User), (ii)
described in clauses (i) through (iii) of Section 10.1 above, (iii)

                                       11
<PAGE>

arising from the performance of a Product or maintenance and support services
rendered or required to be rendered in connection with the distribution of a
Product to an End User, except, if Reseller has purchased maintenance and
support services from Engage, as may be attributed to Engage's failure to render
such maintenance and support services to Reseller, or (iv) any representation,
promise, guarantee or warranty made or implied by Reseller or a subdistributor
to the extent it exceeds or differs from those expressly set forth in the
documentation accompapying a Product, EXCEPT as may be attributed to Engage's
failure to meet the representations, warranties, covenants or other agreements
herein or in the Shareholders Agreement.

     10.3  Use of Engage Name.  The rights and obligations contained in Section
           ------------------
12 of the Shareholders Agreement shall apply in relation to the Products as if
they were set forth in full herein for the benefit of Reseller.

     -----------------------

     11.1  Warranty of Authority.  Engage represents and warrants that it
           ---------------------
possesses the rights in the Products to perform its obligations hereunder.  The
representations, warranties and covenants contained in Clauses 22.2 and 22.4 of
the Shareholders Agreement shall apply in relation to the Products as if they
were set forth in full herein for the benefit of Reseller.

     11.2  DISCLAIMER OF WARRANTIES.  OTHER THAN THE WARRANTIES MADE TO RESELLER
           ------------------------
CONTAINED OR REFERENCED HEREIN, ENGAGE MAKES NO WARRANTIES OR REPRESENTATIONS AS
TO ANY PRODUCT OR AS TO ANY SERVICES RENDERED TO RESELLER OR ANY OTHER PERSON.
ENGAGE RESERVES THE RIGHT TO CHANGE ITS PRODUCT WARRANTY AND SERVICE POLICIES AT
ANY TIME, WITHOUT FURTHER NOTICE AND WITHOUT FURTHER LIABILITY TO RESELLER OR
ANY OTHER PERSON SUBJECT TO THE CONSENT OF RESELLER WHICH CONSENT WILL NOT BE
UNREASONABLY WITHHELD.  EXCEPT AS SET FORTH ABOVE, AND TO THE EXThNT PERMITTED
BY APPUCABLE LAW, ENGAGE DISCLAIMS ALL EXPRESS AND IMPLIED WARRANTIES, ORAL OR
WRITTEN, INCLUDING BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT AND ANY WARRANTIES ARISING
FROM COURSE OF DEALING, COURSE OF PERFORMANCE OR USAGE OF THE TRADE.

     11.3  Acknowledgement.  Reseller acknowledges that the Products have not
           ---------------
been prepared to meet the individual requirements of Reseller or its End Users.

                      ARTICLE 1:  DELIVERIES AND UPDATES

1.1  Delivery of Red Brick Formation.
     -------------------------------

     Immediately following execution of this Agreement Red Brick will provide
Licensee at no cost with one (1) master media containing the beta version of Red

         Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


Formation 1.3 beta to the extent such documentation is then available (together
the "Red Brick Formation Licensed Materials").

     Red Brick's obligation to provide source code for the Red Brick Formation
Licensed Materials will not apply for portions, but only such portions, of the
Red Brick Formation Licensed Materials which are licensed to Red Brick by third
parties under agreements which do not permit the provision to Licensee of a
source code form of such portions of the Red Brick Formation Licensed Materials.
Red Brick's obligation to provide source code for the Red Brick Formation
Licensed Materials also will not apply to portions of the Red Brick Formation
Licensed Materials which are derived from Red Brick Warehouse Products which
existed before Red Brick's acquisition of the Database Technology from Licensee,
do not incorporate, in whole or in part, any of the Database Technology, and
whose absence shall not reduce the functionality of the Red Brick Formation
Licensed Materials or Database Technology below the performance level of such
materials at August 29, 1997, notwithstanding minor software defects which may
have existed as of August 29, 1997.

1.2  Delivery of Database Technology.
     -------------------------------

     Upon completion of the Services requested in Work Order Number One (as such
terms are defined in that certain Consulting Services Agreement entered into
between the parties as of August 29, 1997 ("Consulting Agreement")), Red Brick
shall provide Licensee at no cost with one (1) master media containing the

of each item of all documentation for the Database Technology to the extent such
documentation is then available.

1.3  Updates.
     -------

     Upon the earlier of (i) [**] or (ii) completion of the deliverable
described in Section 3(b) of Work Order Number Two of the Consulting Agreement
(the "Start Date") and for a period of two years thereafter, Red Brick shall
provide Licensee at no cost with one (1) master media containing all Updates in
source code and object code form and one (1) master copy of each item of all
documentation for all Updates to the extent such documentation is then
available.  Beginning [**] after the Start Date, Red Brick shall provide
Licensee with all subsequent Updates at the same time Red Brick makes such
Updates available to its customers, provided Licensee has elected to pay Royalty
                                    --------

         Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


terminate automatically upon the [**] anniversary of the Start Date; provided
that if the last Update provided by Red Brick to Licensee during such [**]
period was made generally available to customers more than [**], then Red Brick
shall provide Licensee with the next Update, at such time as such Update is made
available to customers, at no charge (the period through the later of such
Update or [**] after the Start Date is the "[**] Period").  All Updates provided
by Red Brick to Licensee pursuant to this Section 1.3 shall be deemed part of
the "Licensed Software" for purposes of this Agreement.

     Red Brick's obligation to provide source code for the Updates will not
apply for portions, but only such portions, of the Updates which are licensed to
Red Brick by third parties under agreements which do not permit the provision to
Licensee of a source code form of such portions of the Updates.  Red Brick's
obligation to provide source code for the Updates also will not apply to
portions of the Updates which are derived from Red Brick Warehouse Products
which existed before Red Brick's acquisition of the Database Technology from
Licensee, do not incorporate, in whole or in part, any of the Database
Technology, and whose absence shall not reduce the functionality of the Updates
or Database Technology below the performance level of such materials at August
29, 1997, notwithstanding minor software defects which may have existed as of
August 29, 1997.

1.4  Development of Additional Features for Red Brick Formation.
     ----------------------------------------------------------

     Red Brick will use commercially reasonable efforts to develop and deliver
to Licensee a modified version of the Red Brick Formation Licensed Materials by
[**] (the "Modified Red Brick Formation Licensed Materials").  The Modified Red
Brick Formation Licensed Materials will include the features set forth in
Exhibit 4 attached hereto.  Red Brick will began work on the Modified Red Brick
Formation Licensed Materials [**] of the signing of this Agreement.  Thereafter,
until the Modified Red Brick Formation Licensed Materials are delivered to
Licensee, Red Brick will provide Licensee on a weekly basis with a copy of the
high level project plan for the completion of the Modified Red Brick Formation
Licensed Materials and weekly status against the plan. Failure by Red Brick to
deliver the Modified Red Brick Formation Licensed Materials to Licensee by [**]
shall result in Red Brick being required to make the payments specified below in
compensation of the damages to Licensee for such delay in delivery.  Upon the
end [**], if Red Brick has failed to make delivery of the Modified Red Brick
Formation Licensed Materials by such date, Red Brick shall pay to Licensee the
sum of [**].  As an example, if Red Brick delivers the Modified Red Brick
Formation Licensed Materials on [**],Red Brick would be obligated to pay
Licensee [**].  Red Brick's obligations [**], which maximum payment

        Securities and Exchange Commission. Asterisks denote omissions.


will be reached in the event that delivery of the Modified Red Brick Formation
Licensed Materials [**].

     If Red Brick is not able, through commercially reasonable efforts, to
obtain the third party licenses and rights to the software necessary to develop
and include in the Modified Red Brick Formation Licensed Materials the features
set forth in Exhibit 4, then Licensee will use commercially reasonable efforts
to obtain such rights on behalf of Red Brick and/or to grant such rights to Red
Brick.  If neither Red Brick or Licensee is able to obtain such licenses and
rights for Red Brick's benefit in developing and implementing the features set
forth in Exhibit 4, then Red Brick will not be required to implement the
features, but only such features, in the Modified Red Brick Formation Licensed
Materials, for which the parties are not able to obtain the necessary third
party licenses and rights.

     If Red Brick chooses not to market a specific database adapter set forth in
Exhibit 4 and as such does not obtain the third party licenses and rights to the
software necessary to market such adapter, then, in the event Licensee desires
that the Modified Red Brick Formation Licensed Materials contain such adapter,
Licensee will use commercially reasonable efforts to obtain such rights on
behalf of Red Brick and/or to grant such rights to Red Brick.  If Licensee is
not able to obtain such licenses and rights for Red Brick's benefit in including
a specific database adapter set forth in Exhibit 4, then Red Brick will not be
required to implement the specific adapter, but only such adapter, in the
Modified Red Brick Formation Licensed Materials, for which the Licensee is not
able to obtain the necessary third party licenses and rights.

1.5  Delivery of Modified Red Brick Formation Licensed Materials.
     -----------------------------------------------------------

     Upon completion of the development of the Modified Red Brick Formation
Licensed Materials, Red Brick shall provide Licensee at no cost with one (1)
master media containing the Modified Red Brick Formation Licensed Materials in
both object code and source code form and one (1) master copy of each item of
all documentation for the Modified Red Brick Formation Licensed Materials to the
extent such documentation is then available.

     Red Brick's obligation to provide source code for the Modified Red Brick
Formation Licensed Materials will not apply for portions, but only such
portions, of the Modified Red Brick Formation Licensed Materials which are
licensed to Red Brick by third parties under agreements which do not permit the
provision to Licensee of a source code form of such portions of the Modified Red
Brick Formation Licensed Materials.  Red Brick's obligation to provide source
code for the Modified Red Brick Formation Licensed

Materials also will not apply to portions of the Modified Red Brick Formation
Licensed Materials which are derived from Red Brick Warehouse Products which
existed before Red Brick's acquisition of the Database Technology from Licensee,
do not incorporate, in whole or in part, any of the Database Technology, and
whose absence shall not reduce the functionality of the Modified Red Brick
Formation Licensed Materials or Database Technology below the performance level
of such materials at August 29, 1997, notwithstanding minor software defects
which may have existed as of August 29, 1997.

1.6  Ongoing Support of Modifications.
     --------------------------------

     Red Brick covenants and agrees that for all future versions and Updates to
the Database Technology, Red Brick Formation Licensed Materials and Modified Red
Brick Formation Licensed Materials (the "Licensed Software"), which future
versions and Updates occur subsequent to the development of the Modified Red
Brick Formation Licensed Materials called for by Section 1.4 of this Agreement,
Red Brick will continually maintain, update and support in such future versions
and Updates of the Licensed Software the features set forth on Exhibit 4 hereto.

available to its customers, provided Licensee is current in the payment of all
Royalty Fees and is in good standing under this Agreement; and (b) Licensee
shall be obligated to pay Red Brick the Royalty Fees solely with respect to
revenue recognized from the Application Suite Components incorporating Updates
received after the [**] Period and distributed to its customers in accordance

Each quarter during the term of this Agreement, within fifteen (15) days after
the end of the quarter, Red Brick shall provide Licensee an invoice and report
documenting such costs incurred by Red Brick during the quarter, and a full and
accurate accounting thereof.

     2.5.3  Royalty Fee Reports.  Each quarter during the term of this Agreement

describing any Royalty Fee payments made or due; number of copies of the
Application Suite shipped; the shipment date; and the end user name, address,
hardware, and operating system; as well as any information necessary or useful

parties will also mutually agree upon the terms and responsibilities between the
parties for all installation, training and consultation, and all other
maintenance and support directly to end users with respect to any Licensed
Software incorporated into the Application Suite.

2.7  Escrow of Source Code.  Red Brick agrees that upon the request of a
     ---------------------
licensee of Licensee or its Resellers (known as an "End User"), which End User
has licensed all or any part of the Licensed Software, Red Brick will allow
Licensee or its Resellers to place into an escrow one (1) copy of the latest
version of the source code of all Licensed Software licensed to such End User,
together with all related programmer documentation, instructions, flow charts
and other materials necessary for a reasonably skilled programmer or analyst to
use the said source code to maintain and modify the Licensed Software licensed
to such End User, without the assistance of other persons or reference to other
persons (the "Source Code Materials").  Red Brick shall promptly supplement said
deposit with Source Code Materials for any new Updates, releases or additional
products licensed to Licensee, and sublicensed by Licensee or its Resellers to
End User during the term of this Agreement.  The deposit will be pursuant to the
terms of an agreement (the "Escrow Agreement") among Licensee or its Resellers,
End User and a third party escrow firm of national reputation specializing in
software escrows ("Escrow Agent") and will be in a form mutually acceptable to
such Licensee or its Resellers, End User and Escrow Agent.  In the event such an
Escrow Agreement is established, Red Brick hereby grants to the Licensee, its
Resellers and the End User for whose benefit the escrow is established the
license rights to the Licensed Software which are granted pursuant to the Escrow
Agreement.

     ------------------------

     The parties acknowledge and agree that during the course of performing
their duties under this Agreement, the parties may exchange confidential and

Application Suite, trade secrets, product plans and schedules, new product
information, technical data and know-how, instructional and operating manuals,

Confidential Information of the other party constitutes valuable trade secrets
of that party.  Both parties agree that this Agreement establishes a
confidential relationship between Licensee and Red Brick as to the other party's
Confidential Information.  Each party agrees, therefore, to preserve the
confidential nature of the other party's Confidential Information by retaining
and using such Confidential Information in trust and confidence, solely in
accordance with their rights under this Agreement, and further agrees not to

agreement between the parties) (i) use the Confidential Information; (ii)

neither party shall copy or make, or cause or permit any third party to copy
such Confidential Information, in whole or in part, without the prior written
consent of the other party. A party receiving Confidential Information shall not
be obligated under this Section 3.4 with respect to information the receiving
party can document: (a) is or has become readily publicly available without
restriction through no fault of the receiving party or its employees or agents;
(b) is received without restriction from a third party lawfully in possession of
such information and lawfully empowered to disclose such information; (c) was
rightfully in possession of the receiving party without restriction prior to its

Allocated Application Suite Revenue    Percent due Red Brick as Royalty Fee

              [**]                                   [**]

              [**]                                   [**]

              [**]                                   [**]

              [**]                                   [**]


Where "Allocated Application Suite Revenue" means the aggregate annual revenue
net of returns and allowances recognized by Licensee from the sale,
licensing or distribution of the Application Suite Components incorporating
Updates received by Licensee after the [**] Period.

Royalty Fees are calculated on a graduated basis with the beginning balance
starting from zero each year.  For example, if Allocated Application Suite
Revenue for Year 1 was [**], the Royalty Fee for Year 1 would be calculated as
follows:  [**].  In Year 2, the calculation would begin from $0 again.  Royalty
Fees are calculated based on Total Annual Revenue, but are payable on a
quarterly basis in accordance with Sections 2.5.3 and 2.5.4 of the Agreement.

In addition to Licensee's obligation to pay Royalty Fees, Licensee shall have an
obligation, commencing on the Effective Date of this Agreement, to make Pass-
Through Royalty Fee payments to Red Brick in accordance with Section 2.5.2 of

or "service bureau" purposes the System or Localized System, in whole or in
part, except as specifically permitted herein. Xbeam has the right to request

          ------------------------------------
with written notice of any material breach of this Agreement, including any
misuse of the System or Localized System by Xbeam, where misuse is defined as
any usage beyond that specified in Section 3.2 or expressly authorized under the

time, and that ADSmart's remedy at law for such Misuse is inadequate.

                       Error Correction and Enhancements

Error Correction
- ----------------

     During the terms of this Agreement, ADSmart shall provide error correction
services ("Error Correction Services") pursuant to the following procedures:

Each party shall designate a primary and secondary contact (with telephone,
pager and fax numbers and email addresses) for communications and receipt of
materials related to Error Correction Services.

1.   Each party shall designate a primary and secondary contact (with telephone,
pager and fax numbers and email addresses) for communications and receipt of
materials related to Error Correction Services.

2.   ADSmart's designated representative shall receive and process Xbeam's
reports of~any Errors in the Localized System between the hours of 9:00 a.m. to
5:00 p.m. EST Monday through Friday, excluding ADSmart holidays. For reporting
of a Class 1 Error, an ADSmart representative will be available by pager on a
24-hours per day.

3.   Xbeam shall advise ADSmart of any Error within two (2) working days after
its becoming aware of such Errors. Xbeam shall provide all information
reasonably requested by ADSmart from time to time to assist ADSmart in
identifying and solving the Errors. Xbeam shall bear all shipping charges,
communications charges, and the like that are associated with providing such
data to AD Smart.

4.   ADSmart and Xbeam shall mutually agree to classify reported Errors as
follows:

     Class 1 Error:      Renders the Localized System unusable or the use
                         thereof commercially infeasible.

     Class 2 Error:      Renders a significant function of the Localized System
                         unusable or the use thereof commercially unfeasible.

     Class 3 Error       All other Errors are Class 3 Errors, in particular, all
                         Documentation shortcomings and deviations that do not
                         have the operational or economic consequences as
                         defined for Class 1 and Class 2 Errors shall be deemed
                         Class 3 Errors.

                                       29
<PAGE>

In the event of any dispute related to the classification of an Error, Xbeam's
classification, if reasonable, shall govern.

5.   With respect to Class 1 and Class 2 Errors, within two (2) working days of
receipt of notice of any such Error, ADSmart shall, at no additional charge, use
best efforts to either: (i) provide Xbeam with a response specific to the Errors
described, sufficient to alleviate any adverse effect of the Error on the
utility of the Localized System satisfactory to Xbeam, or (ii) provide Xbeam
with a response describing ADSmart's then-existing diagnosis of the Errors
described and outlining ADSmart's then existing plan and timetable for
correcting the Errors, in which case ADSmart shall report its progress in
correcting the Errors to correcting the Errors. As well as informing Xbeam at
least weekly. In addition, ADSmart shall inform Xbeam of any action that ADSmart
believes should be taken by Xbeam for data preservation or other damage.

6.   With respect to Class 3 Errors ADSmart will respond with a proposed plan of
action back to Xbeam via email within five (5) working days and the parties will
mutually agree on the plan of action.

If Xbeam determines that the Errors will not be corrected by any action as above
and ask reasonably, ADSmart shall dispatch its competent engineer to correct
such Errors.

This paragraph states Xbeam's exclusive remedy and ADSmart's sole obligation~for
Error Correction. Under no circumstances does ADSmart warrant that all Errors
can or will be corrected.


Enhancements
- ------------

Xbeam will notify ADSmart, in writing, of all proposed enhancements to the
System and Localized System. ADSmart will respond with a proposed plan of action
back to Xbeam via email within fourteen working days and the parties will
mutually agree on the plan of action.

                                   --------

Reference is made to Exclusive Strategic Alliance Agreement dated January 7,
1998 (the "Agreement") between Engage Technologies, Inc. ("EG"), ADSmart
Corporation ("ADSmart") and Cross Beam Networks Corporation ("Xbeam").


EG for itself and ADS mart and Sumitomo Corporation for itself and Xbeam hereby
agree as follows:


1.   EG acknowledges that it has acquired the engineering division of ADSmart
     and it shall be responsible for developing the next version of Accipiter
     based ADSmart and also for providing on-going version-up of the same.

2.   EG/ADSmart and SC/Xbeam shall immediately meet to clarify the status of the
     project of such development on the part of ADSmart and shall discuss and
     agree upon (i) the completion date for the localization of the next version
     of Accipiter based ADS mart and (ii) the commencement date of the services
     based on that next version, each of which shall be on or before the end of
     December, 1998. Such next version needs to be acceptable to the customers
     in Japan. Until the completion of such next version, EG shall provide full
     support and assistance utilizing their commercial and technical resources
     in order to keep the reputation and goodwill of ADSmart and keep the
     services of ADSmart attractive to the customers in Japan. EG shall at its
     responsibility procure that the localization and the commencement of the
     services of ADSmart shall be completed by the above-mentioned dates. It is
     a condition to SC's execution of the contract in relation to the
     establishment of a joint venture company between SC and EG for the purpose
     of pursuing the business opportunities in the territory of Japan through
     the commercialization of Internet behavioral profiling and marketing
     products, database subscription services and the performance of related
     consulting services (the "Contract") that the above mentioned dates shall
     have been agreed upon among EG/ADSmart and SC/Xbeam by the end of June,
     1998. For avoidance of doubt, the foregoing shall be without prejudice to
     SC/Xbeam's right to the payment of liquidated damages for delay payable by
     ADSmart under the Agreement.

3.   This Addendum is an integral part of the Agreement. Terms already defined
     in the Agreement but not otherwise defined in this Addendum shall have the
     same meanings defined in the Agreement.

                        SERVICES AND LICENSE AGREEMENT


     This Services and License Agreement ("Agreement"), effective as of October
29, 1997 ("Effective Date"), is made by and between Lycos, Inc., a Delaware
Corporation with a principal place of business at 500 Old Connecticut Path,
Framingham, MA. 01701-4576 ("Lycos"), and Engage Technologies, Inc., a
Massachusetts Corporation with a principal place of business at 100 Brickstone

                                   Recitals
                                   --------

     A.   Lycos is the owner or Licensee of certain Web services (collectively,
the "Lycos Services"), which are accessible through the URL www.lycos.com (the
"Lycos Site");

     B.   Engage provides open, standards-based software solutions that enable
companies to distinguish, understand and engage prospects and customers in
personalized communications over the Web.

     C.   The purpose of this Agreement is to address Lycos' requirement for a
visitor profiling system with the capability to drive visitor-specific
applications.  The system integrates advanced Neural Network technology from
Nestor, Inc. for the decision rule engine with the Engage large-scale
clickstream data processing capability. The system offers an optimized approach
to Lycos' long-term requirements and is aimed at strengthening the Lycos brand
with an industry-leading capability in visitor profiling, clickstream data
mining and personalization of services and content.

     D.   Engage agrees to provide stated service in exchange for Lycos' public
support of the Engage Suite of products and access to Lycos' clickstream data.

     E.   Lycos and Engage desire to enter other arrangements as more
particularly described herein.

     NOW, THEREFORE, for good and valuable consideration, receipt and
sufficiency of which are hereby acknowledged, Lycos and Engage hereby agree as
follows:
<PAGE>

                                     Terms
                                     -----

     1.   Lycos will:
          ----------

     a)   Lycos will provide Engage with the specifications of the various NT-
     based servers on which Engage will install the Web server kits.

     b)   Lycos will provide Engage with a map of Lycos' Web site operations and
     product areas as well as detailed traffic volume data per respective areas
     to enable resource planning at the hosting facility in Andover.  Lycos will
     include a determination of the amount of data it wishes to maintain online
     at Engage's hosting facility.

     c)   Lycos will provide Engage with a content description of Lycos' Web
     site pages to enable classification and will work with Engage in specifying
     the number of categories which should be addressed by the user profiling
     system.

     d)   Lycos will provide a Windows NT-based server at Lycos' operations site
     to load and operate the Engage Discover decision support module.

     e)   Lycos will facilitate and manage the technical interface between
     Engage, Lycos and Accipiter.

     f)   Lycos will work with Nestor Interactive, Inc. ("Nestor") to develop
     the models for the Communication Strategies driving the personalization
     services application and will endeavor in becoming thoroughly familiar in
     the usage of Nestor-provided operator controls for managing Communications
     Strategies and content serving.

     g)   Lycos will provide open access to its operations team for
     representatives of Engage and Nestor, Inc. and will designate a team leader
     on Lycos' side responsibilities for direct interface with the Engage-Nestor

     operations and data communications, b) personalization services, and c)
     advertising management.

     h)   Lycos grants to Engage a non-exclusive, perpetual, world wide, fully
     paid up, royalty free license to use all Lycos, Inc. clickstream data
     provided to Engage under this Agreement.  Engage may retain the clickstream
     data indefinitely and shall be allowed to merge, transform, enhance or
     perform operations on the data for further resale on the marketplace with
     the expressed limitations that (i) such data may not be aggregated and
     presented in a form or manner that would permit it to be identified as
     Lycos' and (ii) such data shall not contain the means to identify personal
     and confidential data provided by Lycos' users and/or the means to
     associate identifiable individual Lycos'

     collateral, press releases (as set forth below) and on the Engage website
     in support of the marketing and sale of commercial versions of the full
     range of Engage' Suite of products. Lycos will provide an overall level of
     marketing support no less than the level of marketing support provided by
     Lycos to Nestor pursuant to that certain Letter Agreement between Lycos and

     incorporated herein by reference. Each promotional item must be approved in

          areas determined by Lycos;
          2.   To generate and update a database of registered users with their
          corresponding interests and activity log data;
          3.   To generate and update a database of anonymous users with their
          corresponding interests and activity log data;
          4.   To generate user profiles from which personalized services and
          targeted content can be served to users;
          5.   To generate user profiles allowing improved ad targeting; and

          6.   To provide reporting and analysis tools for measuring site
          activity.

     b)   Engage will install and test a host server for Lycos' operations at
     Engage's Andover facility.  This host server, defined as "Engage Hosting
     Services", will be configured to provide sufficient data storage and
     processing resources to allow uninterrupted processing of Lycos data on a 7
     day/24 hours per day basis and according to the volume and schedule
     determined by Lycos as well as the length of time required to maintain data
     online.  This is a material term of this Agreement.

     c)   Engage will install and test Web Server kits at Lycos' operations in
     the Windows-NT servers defined by Lycos.  These kits will provide the data
     collection capability (Engage.Journal) and the user registration capability
     (Engage.Portrait).

     d)   Engage will procure, install and test the necessary data communication
     channels, hardware and software, under the sub-contract from Navisite, to
     transmit raw clickstream data from Lycos' operations in Pittsburgh to
     Engage's facility in Andover and return processed user profiles from
     Andover back to Pittsburgh.

     e)   Engage will build the Lycos site classification tables for the
     personalization areas and other sections of Lycos' site which are
     complementary to the search engine function.

     and database at Lycos' site and at the Andover hosting facility providing
     Lycos with the capability to carry out the queries on the processed data.

     designated server.  This module will be used by the applications to
     retrieve user profiles for the content personalization application.

     h)   Engage will provide data inputs in the form of user profiles generated
     by the Engage software to Lycos' ad targeting system (Accipiter) and will
     work with Lycos' advertising management team in formatting the data
     according to the ad server engine requirement and as defined by the Lycos
     technical operations team.

     i)   Engage will develop in conjunction with Nestor, an integrated system
     consisting of Engage user profiling software and Nestor Neural Network rule
     engine.  This is a material provision of this Agreement.  Notwithstanding
     the foregoing, however, Engage shall not be liable for any breach of this

                                      -4-
<PAGE>

     Agreement caused by the failure of any software provided by Nestor if
     Engage procures a reasonably acceptable replacement for such failed
     software within forty-five (45) days after written notice from Lycos.  This
     integrated system will be hosted at Engage's facilities in Andover and will
     be the platform from which Lycos' personalization services servers will
     operate.

     j)   Engage will migrate the full Windows NT-based application to the main
     Lycos operation running under Digital UNIX/Netscape 2.0 (or higher) web
     server environment within 30 days of Lycos upgrading to Netscape 2.0 (or
     higher).

     k)   Engage will provide Lycos with software updates for Engage software
     modules installed at Lycos provided Lycos' operations remain on the server
     software environments discussed above.

     l)   Engage will place in escrow with Data Securities International, Inc.
     ("DSI"), pursuant to the FlexSAFE Escrow Agreement attached hereto as
     Appendix E and incorporated herein by reference, a copy of the source code
     for each component of the Engage Suite that is owned by Engage, e.g.,
     Engage.Journal, Engage.Link, and Engage.Portrait, and Engage will use
     commercially reasonable efforts to acquire the rights to place into escrow,
     for Lycos' protection, the source code for each component of the Engage
     Suite that is licensed by Engage from a third party.  In the event the
     Escrow Material is distributed by the Escrow Agent to the License pursuant
     to the FlexSAFE Escrow Agreement, and provided that Lycos is in compliance
     with the terms of the Software License Agreement attached hereto as
     Appendix D and incorporated herein by reference ("Software License
     Agreement"), Engage hereby grants to Lycos a non-exclusive, non-
     transferable limited license to permit only its employees with a "need to
     know," who have signed a confidentiality agreement with Lycos containing
     terms no less protective of Engage's rights than those in this paragraph,
     the right to use the Source Code only on Lycos' facilities and solely to
     support Lycos' use of the object code form of the Engage Suite as permitted
     in the Software License Agreement.  Lycos shall maintain the Source Code in
     strict confidence and shall not use, reproduce, modify, access, disclose,
     reverse engineer, display, transfer or transmit the Source Code, except as
     expressly permitted herein.  This limited Source Code license is further
     subject to the same Software License Agreement restrictions as govern
     Lycos' use of the Engage Suite, provided that the terms of this Section
     2(1) shall govern over any conflicting terms in the Software License
     Agreement.  Without in any way limiting the generality of the foregoing,
     Licensee shall not be permitted to sell or license the Escrow Material to
     any third party and Lycos shall return the Source Code to Engage
     immediately upon the cure, cancellation, removal or other termination or
     expiration of the event giving rise under the Escrow Agreement to the
     release

                                      -5-

     Escrow Agreement. Engage will pay all future charges owed to DSI, and will
     provide Lycos with proof of payment.

     of Work attached hereto as Appendix B and incorporated herein by reference.

          shall renew automatically for successive one year periods unless
          either party gives written notice of cancellation to the other party
          within thirty (30) days prior to the commencement of any such renewal
          date.

     4.   Pricing.  The pricing for hosting and integration services provided by

Dear Ted:

Reference is made to the request by Lycos, Inc. ("Lycos") that Nestor
Interactive, Inc. ("Nestor") deliver and license a copy or copies of Nestor's
software program called InterSite (the "Nestor Software") to Engage
Technologies, Inc. (the "Licensee") and permit the Licensee to sublicense that
copy or copies to Lycos in conjunction with Licensee's license to Lycos of the
Engage Enterprise Suite (the "Subject Product").

Nestor is willing to so license and deliver the Nestor Software to Licensee
conditioned on and subject to Lycos' agreement to the following:

1.   Lycos shall fully comply with all of the terms and conditions of the
     license of the Subject Product between the Licensee and Lycos.

2.   Lycos and Nestor shall jointly release a press release in the form attached
     hereto, the timing of which shall be subject to both parties' reasonable
     approval, but no later than December 1, 1997.

3.   As long as Lycos uses the Nestor Software, Lycos shall:

     (i)    identify Nestor as Lycos's exclusive vendor of "neural network ad
            targeting software";
     (ii)   maintain on Lycos's Web pages on which the Nestor Software
            participates in ad selection or personalization, a GIF image (the
            placements, compositions and sizes of which shall be similar to
            those of the GIF images of other software providers on such Web
            pages (if any) and shall in any event be subject to Nestor's advance
            approval, which approval shall not be unreasonably withheld), which
            shall be linked to such Web pages as Nestor reasonably may elect
            from time to time;
     (iii)  allow and host such visits to its facilities by potential customers
            for the Nestor Software as Nestor may reasonably request;
     (iv)   participate in such sales conference calls for the Nestor Software
            as Nestor may reasonably request;

     (v)    recommend the Nestor Software as its preferred solution to all
            Lycos's customers (including without limitation Barnes and Noble,
            Prodigy, Accipiter, Planet Direct, GTE Corporation, United Parcel
            Service of America, Inc., and InfoSpace) and other third parties who
            inquire; and
     (vi)   not in any way disparage the Nestor Software to any third party.

4.   Personnel of Lycos reasonably acceptable to Nestor shall present the
     keynote address at the 1998 InterSite User's Group meeting.

5.   If Lycos at any time pays the Licensee a license fee for or in connection
     with the Subject Product, the continued use of the Nestor Software by
     Licensee shall be subject to such fee as Nestor and Lycos shall then agree
     after good faith negotiation.

6.   Nestor may immediately terminate the license of the Nestor Software to the
     Licensee if (i) Lycos and Nestor, each acting in good faith, fail to agree
     on the fees as provided in paragraph 5 of this letter agreement, (ii) if
     Lycos fails to fully and timely perform any of its obligations under this
     letter agreement.

7.   Lycos will provide Nestor with 3,000,000 banner advertisements, on a run of
     site and space available basis, over a three month period.

8.   Nestor assumes no obligation or liability for, and Lycos will indemnify,
     defend and hold Nestor harmless from, any expenses, damages, costs
     (including reasonable attorneys' fees) or losses resulting from, arising

     duties contained in this letter agreement or (ii) the use by Lycos of the
     Nestor Software.

9.   Lycos will maintain the confidentiality of, and not disclose to any third
     party (except the Licensee), the terms and conditions of this letter
     agreement.

10.  THE NESTOR SOFTWARE IS LICENSED TO THE LICENSEE AS-IS.

11.  REGARDLESS OF WHETHER ANY REMEDY HEREIN FAILS OF ITS ESSENTIAL PURPOSE, IN
     NO EVENT WILL NESTOR OR ANY THIRD PARTY SOFTWARE SUPPLIER BE LIABLE FOR ANY
     INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, INDIRECT OR CONSEQUENTIAL DAMAGES
     ARISING OUT OF OR RELATING IN ANY WAY TO THIS LETTER AGREEMENT.  THE NESTOR
     SOFTWARE OR THE USE OF THE SAME (INCLUDING, WITHOUT LIMITATION, DAMAGES FOR
     LOST INFORMATION, LOST SAVINGS, LOST PROFITS OR BUSINESS INTERRUPTION),
     EVEN IF NESTOR AND/OR THE THIRD-PARTY SOFTWARE SUPPLIERS HAVE BEEN
     INFORMED, ARE AWARE, OR SHOULD BE OR HAVE BEEN AWARE, OF THE POSSIBILITY OF
     SUCH

                                      -14-

       Securities and Exchange Commission.  Asterisks denote omissions.

     DAMAGES.  THE SOLE REMEDY FOR ANY DISK OR OTHER MACHINE READABLE MATERIAL

     SUPPLIERS BE LIABLE IN DAMAGES OR OTHERWISE IN EXCESS OF[**].

12.  This letter agreement has been entered into, delivered and is to be
     governed by, construed, interpreted and enforced in accordance with the
     laws of the State of New York (without giving reference to choice-of-law
     provisions) from time to time in effect.  The parties agree that the United

     not apply to any of the transactions which are contemplated by this letter
     agreement.

13.  Any dispute arising out of or relating to this letter agreement, a breach
     hereof, or Lycos' use of the Nestor Software, shall be settled by
     arbitration before one neutral arbitrator (selected from a panel of
     attorneys having experience with the knowledge of computers and the
     computer business) in New York City and administered by the American
     Arbitration Association in accordance with its Commercial Arbitration
     Rules.  Any provisional or equitable remedy which would be available from a
     court of law shall be available from the arbitrator to the Parties.  In any
     such proceeding, limited civil discovery shall be permitted for the
     production of documents, which shall be governed by the Federal Rules of
     Civil Procedure (without reference to any local rules of a particular
     court).  All issues regarding discovery requests shall be decided by the
     arbitrator.  Judgment upon the award of the arbitrator may be enforced in
     any court having jurisdiction with respect thereto.  The parties hereby
     consent to the non-exclusive jurisdiction of the courts of the State of New
     York or to any Federal court located within the State of New York for any
     action (i) to compel arbitration, (ii) to enforce the award of the
     arbitrator or, (iii) at any time prior to the qualification and appointment
     of the arbitrator, for temporary, interim or provisional equitable remedies
     and to service of process in any such action by registered mail, return
     receipt requested, or by any other means provided by law.

subject to export or import control and LYCOS agrees that any such items or the

right, duty or obligation under this Agreement without ENGAGE's prior written
consent.

agreement between the parties with respect to the subject matter hereof.
Different or additional terms contained in purchase orders, other documents
supplied by LYCOS, and all other communications, both oral and written, between

13.5   If any provision or portion of this Agreement or attached Schedule is
held to be unenforceable or invalid, the remaining provisions and portions
thereof shall nevertheless be given full force and effect, and the parties agree
to negotiate, in good faith, a substitute valid provision which most nearly
effects the parties' intent in entering this Agreement or attached Schedule.

13.6   Neither party will be deemed in default of any obligation hereunder nor
be liable for any failure or delay in performance which results directly or
indirectly from any cause beyond its reasonable control, including without
limitation, "Acts of God", acts of civil or military authority, strikes, fire,
theft, delays by suppliers, or action or inaction by the other party or any
third party.

13.7   Nothing in this Agreement shall be construed to imply a joint venture,
partnership or agency relationship between the parties and ENGAGE shall be
considered an independent contractor when performing any Services under this
Agreement.

their duly authorized representatives.

     2.   Co-Branding of Products.
          ------------------------

     (a)  Exclusive Tradenames for Products.  The Parties agree that during the
          -----------------------------------
          term of this Agreement, the Products will be marketed by I/PRO,
          Nielsen and any Reseller only under the tradenames "Nielsen-I/PRO
          I/COUNT" and "Nielsen-I/PRO I/AUDIT", without regard to the sales
          channel employed.

     (b)  Co-Branding of Future Products.  To the extent either Party intends to

          any such Future Products, and Nielsen will have no obligation under
          this Agreement to sell and/or market any Future Products, absent an
          amendment of this Agreement or a new agreement regarding such Future
          Products.

     3.   Sales and Distribution Rights; License Agreements.
          --------------------------------------------------

     (a)  Grant of Marketing Rights.  Subject to the terms and conditions of
          -------------------------
          this Agreement, I/PRO grants to Nielsen a world-wide non-exclusive,
          non-transferable (except as set forth in Section 16(a) hereto) license
          to market the Products and Services to End Customers and to Resellers
          of the Products and Services. Promptly following notice from Nielsen
          of a completed Product sale by Nielsen, Nielsen will enter into a
          license agreement with the End Customer or Reseller and I/PRO will
          implement the Product in accordance with I/PRO's installation
          procedures.

     (b)  License Agreements.  Distribution of the Product to End Customers or
          -------------------
          Resellers shall be made only pursuant to a license agreement executed
          and delivered by the Party (either I/PRO or Nielsen, as the case may
          be), which shall be in such form as the Parties may adopt from time to
          time. Except as expressly provided herein, Nielsen shall have no
          independent right to bind I/PRO to any agreement or to reproduce,
          license or distribute the Products. Nielsen will be provided with the
          opportunity to review the forms of agreements to be used with End
          Customers and Resellers, and may provide I/PRO with suggested
          modifications. I/PRO will promptly evaluate and, when appropriate,
          incorporate such suggestions into I/PRO's form agreements. The Parties
          will review the forms of agreement to be used with End customers and

                                      -3-
<PAGE>

          Resellers and will attempt to establish mutually acceptable forms of
          agreement to be used for such purposes. In the event the Parties are
          unable to agree, each Party shall be entitled to use its preferred
          form of agreement, provided that the terms of such agreement shall not
          impose any material obligation on the other Party not otherwise
          imposed upon that Party herein, or materially disadvantage or
          otherwise damage the legitimate business interests of the other Party.

     (c)  No Restrictions on End Customer Sales.  Each Party may market the
          --------------------------------------
          Products to any End Customer, even if such End User is or could be
          deemed to be a competitor of Nielsen or I/PRO.

     (d)  Notice of I/PRO Resellers.  I/PRO shall provide Nielsen with prompt
          --------------------------
          notice of the identity of all of I/PRO's End customers and Resellers
          for the Products, and all sales by I/PRO of the Products shall be
          subject to the terms and conditions of this Agreement.  If Nielsen has
          objections to any standards and quality levels then practiced by
          Nielsen), Nielsen will document such objections to I/PRO, so that a
          joint decision can be taken on whether the relationship with the
          objectionable Reseller should be continued.  If I/PRO chooses to
          continue its relationship with such Reseller, I/PRO will provide
          Nielsen with a list of End Customers served by the objectionable
          Reseller, and Nielsen will be permitted to notify those customers that
          it is not supporting product sold by that Reseller.  In addition,
          I/PRO shall remove Nielsen's name or logo from Products licensed to
          such objectionable Reseller by I/PRO.

     4.   Joint Sales and Marketing.
          --------------------------

     (a)  Concerted Efforts.  Each Party agrees to use its reasonable efforts to
          ------------------
          sell the Products through all distribution channels that they may deem
          appropriate including, in the case of Nielsen, through all reasonable
          efforts of existing sales organizations within Nielsen Media Research.
          The parties currently anticipate that Nielsen will focus on direct
          sales to End Customers, while I/PRO will focus on indirect sales
          thorough Resellers; provided that each Party may employ either
          indirect or direct sales strategies in such Party's discretion, and it
          is expressly understood and agreed between the parties that nothing
          herein shall prevent either Party from accepting inquiries and
          business from potential customers within the other Party's area of
          focus.

     (b)  Coordination of Efforts.  I/PRO shall be responsible for the
          ------------------------
          coordination of sales and marketing efforts, including the development
          and maintenance of a shared leads and sales database, and the
          scheduling of monthly joint sales meetings.  The parties will
          coordinate their efforts to

                                      -4-
<PAGE>

          ensure that branding, logos, promotional look and product messages
          used by each Party shall be as consistent as possible. I/PRO and
          Nielsen will use reasonable efforts to minimize sales and customer
          conflicts in the Parties' respective sales efforts. Each Party will
          designate a contact person for the other Party with respect to
          activities under this Agreement, and the operational employees form
          the major departments of each Party will establish direct
          relationships.

     (c)  Confirmation of Capacity.  Nielsen agrees that in the course of its
          -------------------------
          sales efforts it will not schedule installations or other service
          activities by I/PRO except with I/PRO's prior confirmation of
          availability of capacity.

     (d)  Reseller Materials.  The Parties shall ensure that the messages and
          ------------------
          materials used by Resellers shall be consistent with those used by the
          Parties. Neither Nielsen nor any Reseller identified by Nielsen will
          make any representations, warranties or guaranties with respect to the
          specifications, features or capabilities of the Products or Services
          that are not consistent with I/PRO's then-current published Product
          descriptions and specifications.

     5.   Price, Payment and Commissions.
          ------------------------------

     (a)  Pricing.  Nielsen and I/PRO will market the Products only in
          --------
          accordance with a pricing schedule to be jointly established from time
          to time by mutual agreement of the Parties. The pricing schedule will
          include a range of allowable discounts applicable under specified
          market and customer conditions. I/PRO and Nielsen may from time to
          time and by mutual agreement change the prices and discounts set forth
          on the rate card. Pricing for separate but related Products and
          related services will identify each component separately and will be
          consistently valued.

     (b)  Commissions.
          ------------

               (i)  Amount. During the term of this Agreement, I/PRO will pay to
                    ------
Nielsen commissions equal to a percentage of Net Revenues (as defined below)
from Products (a) sold primarily through the efforts of Nielsen (or through any
Reseller identified and closed by Nielsen), in the percentage amounts set forth
on Exhibit B with respect to sales to U.S.-based End customers or Resellers
   ---------
("U.S. Customers"); and (b) sold primarily through the efforts of I/PRO (or by
any Reseller not identified and closed by Nielsen), in the percentage amounts
set forth on Exhibit C with respect to sales to U.S. Customers. The Parties
             ---------
agree to negotiate in good faith to set Commissions payable on sales to
non-U.S.-based End Customers and

                                      -5-

         Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission.  Asterisks denote omissions.

Resellers ("foreign Customers") on a country-by-country basis.  If the Parties
cannot agree upon Commissions payable to Foreign Customers in any particular
country within thirty (30) days of the commencement of such good faith
negotiations, which thirty-day period shall begin to run upon receipt by one
Party of written notice that the other Party desires to begin such negotiations
accompanied by such information as the notifying party believes, in good faith,
provides a well-founded basis for the commissions proposed by the notifying
Party, then Commissions payable with respect to such sales in such country shall
be as set forth on Exhibit B (with respect to sales by Nielsen), or Exhibit C
                   ---------                                        ---------
(with respect to sales by I/PRO), as the case may be. The Parties recognize that
because the costs associated with sales and service for Foreign Customers are
likely higher than for U.S. Customers, prices of the Products and Commissions
payable on sales of the Products to Foreign Customers may be adjusted upon
mutual agreement of the Parties.  As used herein, "Net Revenues" means[**].
Each Party will invoice its respective Customers or Resellers.  Commissions will
be paid to Nielsen at the end of each quarter with respect to Net Revenues and
accounts which are thirty (30) days or more overdue.  It is understood that
whichever Party is responsible in law for the payment of taxes (if any) upon
revenues received from a Customer or Reseller shall pay such taxes, and shall be
responsible for the collection of such taxes.

          (ii)      Disputes.  The Parties agree to mutually determine in good
                    ---------
faith the amount of commission due in the event that I/PRO and Nielsen shall
disagree as to the Party responsible for the sale to the End Customer or
Reseller.  I/PRO agrees to give Nielsen credit and pay Nielsen in accordance
with Exhibit B for any End Customers or Resellers over which a reasonable
     ---------
conflict arises.

          (iii)     Adjustments.  The commissions set forth on Exhibit B and
                    ------------                               ---------
Exhibit C may be adjusted by mutual agreement of the Parties to reflect changes
- ---------
in pricing, costs, and market conditions, as the case may be. The Parties
acknowledge and agree that commissions must be set and periodically adjusted so
that prices can remain competitive with the marketplace, provide a reasonable
profit to I/PRO in each Product category, and a reasonable compensation to
Nielsen for its sales, support, and promotional efforts. In addition to
adjustments to commissions, the Parties also agree to consider other alternate
means of responding to competitive pressures on pricing of the Products.
Commissions on Future Products, if any, Parties subject to this Agreement will
be established upon mutual agreement of the Parties.

          (iv)      During the term of this Agreement, and for a period of two
(2) years thereafter, each Party will maintain books and records in connection
with its sales and marketing of the Products pursuant to this Agreement in
sufficient

                                      -6-
<PAGE>

detail to permit the other Party to verify compliance with the terms and
conditions of this Agreement. Each Party will have the right through its
independent auditors to inspect such books and records of the other Party solely
to verify the amount of commissions payable pursuant to this Section 5. Any such
audit will be conducted on reasonable notice and during regular business hours
and will not interfere unreasonably with either Party's business activities.
Audits will be made not more than twice annually.

     6.   Product Development and Maintenance.  I/PRO will use its best efforts
          ------------------------------------
to ensure high quality standards for the Products, and will use its best efforts
to resolve any errors in systems or reports. I/PRO will be responsible for
Product Development. I/PRO agrees to consider suggestions and requirements of
the respective sales personnel of each Party, as well as customer response data
and feedback, and shall make such enhancements to the Products as are reasonable
and appropriate in light of overall technical and operational constraints of
I/PRO. I/PRO will schedule monthly coordination meetings between its Product
Development staff and sales personnel of each Party as an aid in meeting its
Product Development obligations. I/PRO will devote its reasonable best efforts
to continue to provide superior value to End Customers, including sufficient
resources to maintain the Products. I/PRO acknowledges that it is I/PRO's
intention to develop and maintain Products that are deemed in customer technical
evaluations to be demonstrably superior overall to similarly priced competitive
products. If at any time a majority of customer technical evaluations clearly
indicate that the Products are inferior overall to similarly priced competitive
products, Nielsen shall provide I/PRO with the results of such studies and shall
make specific recommendations (the "Recommendations") regarding the manner in
which the Products shall be improved. I/PRO shall have a reasonable time, which
shall not be less than six (6) months or substantially more than nine (9)
months, to implement the Recommendations. If after such period a majority of
customer technical evaluations clearly indicate that, for the reasons addressed
by the Recommendations, the Product is inferior overall to similarly priced
competitive products, Nielsen shall have the right to terminate this Agreement
upon 30 days written notice to I/PRO.

     7.   Support.  Each Party shall be responsible, through its respective
          --------
sales organization and at its own expense, to provide an initial response to End
Customers and Resellers closed by such Party as to questions concerning
technical issues, problems or questions regarding the Products. Further
Technical Support will be provided solely by I/PRO, in accordance with I/PRO's
customer support policies in effect from time to time. Nielsen shall have the
right, at Nielsen's expense, to supplement the Technical Support provided by
I/PRO. If at any time Nielsen can demonstrate to I/PRO based upon significant
indications of customer dissatisfaction that I/PRO's technical support is
insufficient to meet the needs of End Customers and Resellers, Nielsen and I/PRO
shall work together to establish adequate customer support, which shall be
financed by appropriate offsets to commissions payable, or

                                      -7-

         Confidential Materials omitted and filed separately with the

such other method upon which the parties mutually agree. In addition, Nielsen
may provide additional analysis products and services to I/COUNT End Customers.
Nielsen may price such products and services separately; provided that the I/PRO
will receive a commission upon such products and services which is mutually
acceptable to both Parties. Nielsen may at its own expense also set up a hot-
line for third party I/AUDIT support, in addition to the standard I/AUDIT
support provided by I/PRO.

     8.   Exclusivity.
          ------------

     (a)  No Substantially Similar Agreements.  During the term of the
          ------------------------------------
          Agreement, I/PRO will not enter into any other comprehensive
          agreement, such as this one, for the co-branding and marketing of the
          Products; provided that I/PRO shall be permitted to enter into
          bundling relationships with respect to other companies' products or
          services.

     (b)  [**].  During the term of this Agreement, [**] will include a [**] and
          other material terms [**].  In the event that [**].  Information [**]
          shall be deemed to be Confidential Information [**], and shall be
          treated in accordance with Section 10 of this Agreement.  [**].  The
          Parties hereby expressly acknowledge that Nielsen's relationship with
          Anywhere Online shall not be subject to this Section 8(b).

     (c)  Derivative Informational Products and Services.  The Parties may, upon
          -----------------------------------------------
          mutual agreement, develop and brand derivative informational products
          and services based on data collected through use of the Products sold
          pursuant to this Agreement.  The Parties will share the revenues from
          such products in such manner as the Parties may agree.

     9.   Property Rights.
          ----------------

     (a)  Intellectual Property Rights.  I/PRO and Nielsen acknowledge and agree
          ----------------------------
          that I/PRO owns all of the I/PRO Proprietary Rights.  Any use by
          Nielsen of such I/PRO Proprietary Rights is authorized only for the
          purposes herein set forth and upon termination of this Agreement for
          any reason, such authorization will cease.  Nielsen and I/PRO
          acknowledge and agree that Nielsen owns all of the Nielsen Proprietary
          Rights.  Any use by I/PRO of such Nielsen Proprietary Rights is
          authorized only for the purposes herein set forth and upon termination
          of this Agreement for any reason, such authorization will cease.

                                      -8-
<PAGE>

          Ownership of products and services developed jointly by the Parties in
          the future shall be determined by mutual agreement of the Parties.

     (b)  No Other Rights.  Nielsen may not, directly or through any person or
          ----------------
          entity, in any form or manner, copy, distribute, reproduce,
          incorporate, use or allow access to the Products or modify, prepare
          derivative works of, decompile, reverse engineer, disassemble or
          otherwise attempt to derive source code or object code from the
          Products, except as I/PRO may agree in writing.  Each Party will take
          appropriate steps with End Customers and Resellers, as the other Party
          may reasonably request, to inform them of and assure their compliance
          with the restrictions contained in this Agreement.

     (c)  Proprietary Notices.  Neither Party will remove from any copy of the
          --------------------
          Products any copyright and other proprietary notices of the other
          Party.

     (d)  Use of Trademarks.  Subject to the terms and conditions of this
          ------------------
          Agreement, during the term of this Agreement each Party grants to the
          other a non-exclusive, world-wide license to use the other Party's
          tradename and trademarks (collectively, the "Trademarks") to the
          extent included in the Product names set forth in Section 2(a), and
          for the purpose of marketing and selling the Products; provided that
          the user submits all such media to the other Party for prior approval
          and follows reasonable trademark usage guidelines communicated by the
          other Party. Each Party understands that the other has applied for
          and/or obtained applicable federal and state registration of certain
          of the Trademarks and agrees, to so indicate on the box containing the
          Products and in any advertisement, promotional materials or other
          documents that contain the Trademarks. Except as expressly provided
          herein, their Agreement shall not be construed to grant to any Party
          any right, title or interest in the other's Trademarks. Upon
          termination of this Agreement for any reason, each Party will
          immediately cease all use of Products' names and Trademarks and
          destroy or deliver to the other Party all materials in the user's
          control or possession which bear such names and trademarks, including
          any sales literature. At no time during or after the term of this
          Agreement will either Party challenge or assist others to challenge
          the other's Trademarks or the registration thereof or attempt to
          register any trademarks, marks or tradenames confusingly similar to
          those of the other. Each Party will present and promote the sale of
          the Products and Services fairly.

     10.  Confidentiality.
          ----------------

     (a)  General.  Except as provided in this Agreement, each Party will not
          --------
          use in any way for its own account of any third party, nor disclose to
          any third party, any such Confidential Information revealed to it by
          the other Party. Each Party agrees to protect any Confidential
          Information from disclosure to others with at least the same degree of
          care as that which is accorded to its own proprietary information, but
          in no event with less than reasonable care. In the event of
          termination of this Agreement, each Party agrees not use or disclose
          any Confidential Information, to destroy or return all written or
          electronic copies of Confidential Information of the other Party and
          each Party will not develop or have developed any product programs
          utilizing any of the Confidential Information.

     (b)  Exceptions.  The foregoing restrictions will not apply to information
          -----------
          that (i) is known to each Party at the time of disclosure to that
          Party as demonstrated by written or electronic records of the
          receiving Party, (ii) has become publicly known through no wrongful
          act of the receiving Party, (iii) has been rightfully received by a
          Party from a third party authorized to make such disclosure without
          restriction, or (iv) has been approved for release by written
          authorization of the disclosing Party.

     (c)  Notice.  Each Party agrees to notify the other promptly in the event
          -------
          of any breach of confidentiality its security under conditions in
          which it would appear that any Confidential Information was prejudiced
          or exposed to loss.  Each Party shall, upon request of the other, take
          all reasonable steps necessary to recover any confidential Information
          disclosed to or placed in the possession of the receiving Party by
          virtue of this Agreement.  The cost of taking such actions shall be
          borne solely by the breaching Party.

     (d)  Non-Disclosure Agreement.  The parties agree that the Non-Disclosure
          -------------------------
          Agreement dated January 20, 1995 shall remain in full force and effect
          as to disclosures made prior to the date of this Agreement.

     11.  Indemnity.
          ---------

     (a)  Indemnification by I/PRO.  I/PRO agrees, at its own expense, to defend
          ------------------------
          or at its option to settle any claim or action brought against Nielsen
          on the issue of infringement of any patent, copyright or other
          intellectual property right of any third party by the Products as used
          or distributed within the scope of this Agreement, and to indemnify
          Nielsen against all damages and costs, including reasonable legal
          fees, which may be

                                      -10-
<PAGE>

          assessed against Nielsen under any such claim or action; provided that
                                                                   --------
          Nielsen provides I/PRO with (i) prompt written notice of such claim or
          action, (ii) sole control and authority over the defense or settlement
          of such claim or action and (iii) the authority, information and
          assistance that is reasonably necessary for defense or settlement of
          the claim or action. In the event that the Products, or a part
          thereof, are held, or in I/PRO's sole opinion, may be held to
          constitute an infringement, I/PRO, at its option and expense, may
          either (w) procure, at no additional cost to Nielsen or any and all
          End Customers or Resellers with whom Nielsen has completed a Product
          sale, the right to continue to use the Product(s), (x) modify the
          Products so they become non-infringing, (y) replace the Products with
          functionally equivalent non-infringing materials reasonably acceptable
          to Nielsen or (z) accept return of the Products. Notwithstanding the
          foregoing, I/PRO will have no liability if the alleged infringement
          arises from (i) the use, in the manner specified in relevant I/PRO
          documentation, of other than a then current release of the Products,
          or (ii) combinations of the Products with non-I/PRO programs or
          products, including any Nielsen products, unless such combination is
          authorized in advance in writing by I/PRO. THE FOREGOING STATES THE
          ENTIRE LIABILITY AND OBLIGATIONS OF I/PRO AND THE EXCLUSIVE REMEDY OF
          NIELSEN, WITH RESPECT TO ANY ALLEGED OR ACTUAL INFRINGEMENT OF
          PATENTS, COPYRIGHTS, TRADE SECRETS, TRADEMARKS OR OTHER INTELLECTUAL
          PROPERTY RIGHTS BY THE PRODUCTS. In addition, I/PRO agrees to
          indemnify and hold Nielsen harmless from and against any cost, loss,
          expense (including attorney's fees) resulting from any and all claims
          by third parties for loss, damage or injury allegedly caused by any
          wrongful act, misrepresentation or omission by I/PRO in connection
          with I/PRO's activities under this Agreement; Nielsen has have the
          right to participate at its expense in any such dispute.

     (b)  Indemnification by Nielsen.  Nielsen agrees to indemnify and hold
          --------------------------
          I/PRO harmless from and against any cost, loss, expense (including
          attorney's fees) resulting from any and all claims by third parties
          for loss, damage or injury allegedly caused by any wrongful act,
          misrepresentation or omission by Nielsen in connection with Nielsen's
          activities under this Agreement; I/PRO shall have the right to
          participate at its expense in any such dispute.  Notwithstanding the
          foregoing, Nielsen assumes no liability hereunder for claims or
          actions resulting from or arising out of the design, development
          and/or operation of the Products.

     12.  Warranty Disclaimer.  EXCEPT AS EXPRESSLY PROVIDED HEREIN, I/PRO
          -------------------
GRANTS NO WARRANTIES, EXPRESS OR IMPLIED, BY STATUTE OR OTHERWISE, REGARDING THE
PRODUCTS, THEIR FITNESS FOR ANY PURPOSE, THEIR QUALITY, THEIR MERCHANTABILITY,
OR OTHERWISE.

     13.  Termination.
          -----------

     (a)  Term.  This Agreement shall become effective on the date first written
          ----
          on this Agreement and shall continue for a period of three (3) years,
          and shall be continued thereafter unless either Party notifies the
          other of termination of the Agreement not less than nine (9) months
          prior to the effective date of such termination.

     (b)  Termination for Cause.  Either Party may terminate this Agreement at
          ---------------------
          any time if the other Party materially breaches this Agreement and
          fails to cure such breach within sixty (60) days after written notice
          of such breach, or if the other Party shall become insolvent, or if
          either Party makes an assignment for the benefit of creditors, or if
          there are instituted by or against either party proceedings in
          bankruptcy or under any insolvency or similar law or for
          reorganization, receivership or dissolution.

     (c)  Termination Liability.  Neither party shall be liable in any manner on
          ---------------------
          account of such Party's determination on termination or cancellation
          of this Agreement in accordance with its terms.  Each Party shall
          immediately discontinue all advertising and marketing references of
          any kind to the other Party and/or its products upon such termination
          or cancellation.  The rights of termination and cancellation as set
          forth herein are absolute.

     (d)  Obligations Upon Termination.  The termination or expiration of this
          ----------------------------
          Agreement shall in no way relieve either party from its obligations to
          pay the other any sums accrued hereunder prior to such termination or
          expiration.

     14.  Limitation of Liability.  EXCEPT AS SET FORTH IN SECTION 11 HERETO,
          -----------------------
NEITHER I/PRO NOR NIELSEN SHALL HAVE ANY LIABILITY TO THE OTHER, FOR ANY LOST
PROFITS OR COSTS OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR FOR ANY
INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES HOWEVER CAUSED AND WHETHER ARISING
UNDER CONTRACT, TORT OR OTHER THEORY OF LIABILITY. IT IS ACKNOWLEDGED BY THE
PARTIES THAT NOTHING IN THIS SECTION 14 SHALL LIMIT A PARTY'S OBLIGATION TO PAY
AMOUNTS ALREADY DUE AND OWING TO THE OTHER PARTY. THESE LIMITATIONS SHALL APPLY

                                      -12-
<PAGE>

NOTWITHSTANDING THE FAILURE OF THE ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

     15.  Certain Equity Matters.  The Parties acknowledge and agree that,
          ----------------------
concurrently with the execution and delivery of this Agreement, I/PRO is
delivering to Nielsen certain warrants to purchase Common Stock of I/PRO.  I/PRO
also agrees during the term of this Agreement to provide notice of each meeting
of I/PRO's Board of Directors and will permit a representative of Nielsen (who
shall be reasonably acceptable to I/PRO) to attend such meetings, without any
power to vote and subject to exclusion with respect to any portion of any Board
meeting which, in the good faith determination of I/PRO's Board of Directors,
involves confidential information of I/PRO disclosure of which to Nielsen would
be expected to involve a conflict of interest detrimental to I/PRO.  Nielsen
may, upon appropriate notice to I/PRO's President or Chairman of the Board of
Directors, submit appropriate matters for the agenda at any such Board meeting.

     16.  Miscellaneous.
          -------------

     (a)  Assignment.  This Agreement will be binding upon and inure to the
          ----------
          benefit of the parties hereto and their permitted successors and
          assigns. Notwithstanding the foregoing, neither this Agreement, nor
          any rights or obligations hereunder, may be assigned or otherwise
          transferred by either Party, except to any successor to all or
          substantially all of such Party's assets or a majority of the voting
          power of such Party's capital stock or, in the case of Nielsen, to an
          assignee of or successor to substantially all of the business or
          assets of Nielsen's Nielsen Media Research division.  Any other
          assignment or transfer without prior written consent will be null and
          void.

     (b)  Severability.  If one or more provisions of this Agreement are held to
          ------------
          be unenforceable under applicable law, the parties agree to
          renegotiate such provision in good faith.  In the event that the
          parties cannot reach a mutually agreeable and enforceable replacement
          for such provision, then (x) such provision shall be excluded from
          this Agreement, (y) the balance of the Agreement shall be interpreted
          as if such provision were so excluded and (z) the balance of the
          Agreement shall be enforceable in accordance with its terms.

     (c)  Legal Expenses.  The prevailing party in any legal action brought by

         at any time before the Surveyor has determined it.

8.2.3    The Landlord and the Tenant may agree that, taking into account the

         after that Review Date.

8.2.4    If the Landlord and the Tenant have not agreed the Open Market Rent

         which will be deemed due as additional rent and recoverable as rent in
         arrears.

8.4.5    The Landlord will not be liable to the Tenant for any failure of the
         Surveyor to determine the Open Market Rent as instructed.

         relevant Review Date, then the Rent shall continue to be payable at the

         the period from the relevant Review Date until that Quarter Day will
         become due together with interest on that shortfall at the Base Rate
         from the date or dates on which such shortfall became due.

         Landlord will be entitled to require a review of the Rent in accordance
         with this clause, except that the revised Rent will be the highest of:

8.6.1    the Open Market Rent at that further Review Date;

8.6.2    the Rent reserved immediately before that further Review Date; and

8.6.3    the Rent reserved immediately before the relevant legislative
         restriction became applicable to this Lease.

8.7      Guarantors not to take part in the review

10.2.1   If the Premises, or any part of the Building over which the Tenant
         exercises rights granted by this Lease, are damaged or destroyed by an
         Insured Risk, then:

         (a)   unless payment of any insurance monies is refused because of any

         (b)   subject to the Landlord being able to obtain any necessary
               consents; and

         Premises;

10.3.3   pay on demand a fair proportion of the costs incurred or payable by the

         least three years after any previous such valuation;

10.3.4   comply with the requirements of the insurers relating to the Premises
         and the rights granted to the Tenant by this Lease;

10.3.5   not do or omit to do anything which may make any insurance of the
         Building or of any adjoining property of the Landlord, taken out by the
         Landlord or any superior landlord, void or voidable, or which would
         result in an increase in the premiums for such insurance;

10.3.6   give the Landlord immediate written notice of any damage to or

         the Building, or any adjoining property of the Landlord, by an Insured
         Risk, because of any act or omission of the Tenant;

         from any insurance taken out by the Landlord; and

10.3.11  not take out any insurance of the Premises against the Insured Risks in
         its own name other than in respect of any part of the Premises
         installed by or on behalf of the Tenant or any undertenant or any other
         occupier, and other than in respect of any plate glass at the Premises.

         the means of access restored; or the Service Media over which the
         rights are exercised are repaired or restored.

10.4.3   The Rent will not be suspended to the extent that any loss of rent
         insurance has been made ineffective, or payment of it has been refused
         by the insurers because of any act or omission by the Tenant.

                            discretion, and from time to time, provides for the

11.2      Landlord's obligations

11.2.1    The Landlord shall provide the Services in a manner which the Landlord
          reasonably considers appropriate.

11.2.2    The Landlord will have no liability for any failure or interruption of
          any Service:

          (a)  while the Tenant is in arrears with payment of the Rent or other
               sums due under this Lease;

          (b)  during the proper inspection, maintenance, repair or replacement
               of any relevant Service Media or equipment;

          (c)  resulting from a shortage of fuel, water, materials or labour;

          (d)  resulting from a breakdown of any equipment used in connection
               with the provision of the Services; or

          (e)  resulting from act or omission of any employee, contractor or
               agent of the Landlord,

               or for any other reason beyond the reasonable control of the
               Landlord.

11.2.3    In the circumstances mentioned in paragraphs (b), (c), (d) and (e)
          above, the Landlord shall restore the relevant Service as soon as is
          reasonably practicable.

11.2.4    The Landlord shall produce the Certificate to the Tenant as soon as
          practicable after the end of the Service Charge Year.

11.2.5    The Landlord shall, but at the cost of the Tenant, allow the Tenant to
          inspect any invoices and receipts for the Services as long as the
          Tenant has given the Landlord reasonable written notice.

11.2.6    If any Office in the Building is unlet for any period, the Landlord
          shall bear a fair proportion of the Landlord's Expenses in respect of
          that Office.

11.3      Tenant's obligations

11.3.1    The Tenant shall pay the Service Charge Estimate, and any VAT on it
          and the Service Charge Balance, and any VAT on it as provided in
          clause 7.1 (Tenant's obligation to pay rent).

                                      37
<PAGE>

11.3.2   If the date of this deed does not coincide with the beginning of a
         Service Charge Year, the Service Charge due from the Tenant for the
         part of that Service Charge Year which is within the Term will be
         reduced by the proportion which the part of that Service Charge Year
         which is before the beginning of the Term bears to one year, and the
         Service Charge Estimate for that part of that Service Charge Year will
         be adjusted accordingly.

11.3.3   If the end of the Term does not coincide with the end of a Service
         Charge Year, the Service Charge due from the Tenant for the part of
         that Service Charge Year which is within the Term will be reduced by
         the proportion which the part of that Service Charge Year which is
         after the end of the Term bears to one year.

11.4     Estimating and revising the Service Charge

11.4.1   The Landlord shall give the Tenant a statement of the Service Charge
         Estimate for each Service Charge Year. Until the statement has been
         given, the Service Charge Estimate shall be payable at the rate of the
         Service Charge Estimate for the previous Service Charge Year. Once the
         statement has been given, the remaining installments of the Service
         Charge Estimate and any VAT on them will be adjusted so as to provide
         for payment of the whole Service Charge Estimate for that Service
         Charge Year to be paid during the year.

11.4.2   If, during a Service Charge Year, the Landlord reasonably expects the
         cost of the Services to increase materially above its previous estimate
         of the cost of the Services for that Service Charge Year, the Landlord
         may revise its estimate of those costs. The Service Charge Estimate
         will be based on that revised estimate and the remaining installments
         of the Service Charge Estimate adjusted so that the revised Service
         Charge Estimate will have been paid by the end of that Service Charge
         Year. The Landlord may revise the Service Charge Estimate more than
         once in a Service Charge Year.

11.5     General provisions

11.5.1   In the absence of manifest error, the Certificate will be conclusive as
         to the amount of the Service Charge.

11.5.2   The Landlord shall notify the Tenant in writing of any change in the
         date of the beginning of the Service Charge Year.

11.5.3   If the Service Charge for any Service Charge Year is less than the
         Service Charge Estimate (as and if revised), the balance will be
         credited against the installments of the Service Charge Estimate due
         from the Tenant in the

                                      38
<PAGE>

         following Service Charge Year, or, at the end of the Term, set off
         against any sums due from the Tenant to the Landlord with any balance
         being repaid to the Tenant.

11.5.4   The Landlord's Expenses for the Service Charge Year in which the
         beginning of the Term falls may include costs incurred by or provided
         for or on behalf of the Landlord before the beginning of the Term so
         far as they relate to Services which are to be provided during the
         Term. The Landlord's Expenses in any Service Charge Year may include
         provisions for expenses to be made after the end of the Term so far as
         such provisions are reasonable having regard to the Services which are
         provided during the Term.

          the matter.

20.9      Sale of goods after end of Term

20.9.1    The Tenant irrevocably appoints the Landlord as its agent to store or

          Working Days after the end of the Term.

20.9.2    The Landlord may store or dispose of such items after that time as it
          thinks fit and without any liability to the Tenant, other than to

          costs of sale or storage incurred by the Landlord.

20.9.3    The Tenant agrees to indemnify the Landlord against any liability
          incurred by the Landlord by reason of the Landlord disposing of any

CLAUSE 23

23.1      In this clause 23 "Termination Date" means 24 March 2004;

23.2      Subject to the pre-conditions contained in clause 23.3 being satisfied
          on the Termination Date, and subject to the provisions of clause 23.4
          either party may determine the Term on the Termination Date by giving
          to the other not less than six month's written notice. The Term will
          then determine on the Termination Date, but without prejudice to any
          rights of either party against the other for any antecedent breach of
          its obligations under this Lease.

23.3      The pre-conditions are that:

23.3.1    (in the case only of a notice served by the Tenant) materially the
          Premises are in a state consistent with the proper performance of the
          Tenant's obligations contained in clause 12;

23.3.2    (in the case only of a notice served by the Tenant) vacant possession
          of the whole of the Premises is given to the Landlord;

23.3.3    the party giving the notice referred to in clause 23.2 pays to the
          other party a sum equal to 3 months' Rent at the rate of the Rent per
          annum payable immediately preceding the Termination Date;

23.3.4    (in the case only of a notice served by the Tenant) all Rent and other
          sums due under this Lease up to the Termination Date have been paid in
          full.

23.4      In the case only where the notice referred to in clause 23.2 is served
          by the Tenant the Landlord may waive any of the pre-conditions
          contained in clause 23.3 at any time before the Termination Date by
          written notice to the Tenant.

23.5      In the case where the notice referred to in clause 23.2 is served by
          the Landlord this Lease shall determine notwithstanding that the
          Landlord has not made payment as referred to in clause 23.3.3 but in
          such event the liability of the Landlord to make such payment shall
          remain.

23.6      Time will be of the essence for the purposes of this clause 23.

          and in full, the Guarantor agrees not, without the consent of the
          Landlord with such consent not to be unreasonably withheld or delayed,
          to:

          be guaranteed under this deed against the Tenant or any other person
          who is liable;

7.1.2     demand or accept any security from the Tenant or any other person who

after receipt of such dividends, compositions and moneys, may remain owing or
expressed to be owing to the Landlord.

GUARANTOR TO TAKE A NEW LEASE

- --------------------------------------------------------------------------------

CLAUSE 9

9.1       In this clause a "Relevant Event" is:

9.1.1     the surrender of disclaimer of the Lease, or the Tenant's obligations
          under it by a liquidator or trustee in bankruptcy of the Tenant;

9.1.2     the disclaimer of the Lease after it has become bona vacantia;

9.1.3     the forfeiture of the Lease; or

9.1.4     the Tenant (being a body corporate) ceasing to exist (whether or not
          the Tenant is capable of being reconstituted or reinstated).

9.2       If a Relevant Event occurs the Guarantor agrees, at the request of the
          Landlord made within 12 months following the Landlord having notice of
          the Relevant Event, to take a new lease of the Premises from the
          Landlord.

9.3       Such new lease shall:

9.3.1     be for a term commencing on the date of the Relevant Event and be
          equal to the unexpired residue of the term of years granted by the
          Lease (or the residue which would be unexpired but for the Relevant
          Event) as at the date of the Relevant Event;

9.3.2     reserve a rent equal to the Rent reserved under the Lease immediately
          before the Relevant Event and otherwise be on the same terms as the
          Lease; and

9.3.3     take effect from the date of the Relevant Event.

9.4       The new lease will take effect subject to the Lease, if and to the
          extent that it is still subsisting, and subject to any underlease or
          other interest created or permitted by the Tenant or its predecessors
          in title.

9.5       The Guarantor shall pay the Landlord's costs (on an indemnity basis)
          in connection with the grant of such new lease and shall execute
          deliver and pay the stamp duty on a counterpart of it to the Landlord.

9.6       The Guarantor shall before the grant of such new lease make a joint
          application with the Landlord (in a form reasonably determined by the
          Landlord) to a court of competent jurisdiction for an order to be made

                                       77

          authorizing an agreement between the Landlord and the Guarantor to
          exclude the provisions of sections 24 to 28 of the Landlord and Tenant
          Act 1954 from the tenancy to be created by the new lease.

9.7       If the Landlord does not require the Guarantor to take a new lease of
          the Premises, the Guarantor shall nevertheless pay on demand to the
          Landlord a sum equal to the Rent and other sums due under the Lease
          which would have been payable but for the Relevant Event in respect of
          the period from the date of the Relevant Event until six months after
          it or, if sooner, the date the Premises are re-let.

SUPPLEMENTARY PROVISIONS

- --------------------------------------------------------------------------------

CLAUSE 10

10.1      This deed is in addition to any other security or any other right or
          remedy held by or available to the Landlord from time to time.

10.2      As and when called upon to do so by either the Landlord or the Tenant,
          the Guarantor shall enter into any document supplemental to the Lease
          (by deed if required) for the purpose of consenting to the Tenant
          entering into such supplemental document and confirming that, subject
          only to subsection 18(3) of the Landlord and Tenant (Covenants) Act
          1995 (Effect of variations on guarantors), all the obligations of the
          Guarantor will remain in full force and effect in respect of the
          Lease.

10.3      The Guarantor agrees to pay to the Landlord on demand, and on an
          indemnity basis, all legal and other costs and charges which may be
          payable by the Landlord in relation to the enforcement of the
          Guarantor's obligations in this deed.

10.4      The Guarantor agrees to pay interest on each amount demanded of it
          under this deed, at the Interest Rate until payment (both before and
          after any judgment), except that where the sum demanded from the
          Guarantor is interest due from the Tenant at that rate and is paid by
          the Guarantor immediately on demand, the Guarantor will not be liable
          to pay further interest on that sum.

10.5      Each of the provisions of this deed is distinct and severable from the
          others, and if at any time one or more such provisions is or becomes
          illegal, invalid or unenforceable (either wholly or to any extent),
          the validity, legality and enforceability of the remaining provisions
          (or the same provision to any other extent) will not be affected or

     This Agreement is made as of the _____ day of ________ 1999, by and between
Engage Technologies, Inc., a Delaware corporation (the "Corporation), and

     WHEREAS, it is essential to the Corporation to retain and attract as
directors the most capable persons available, and

     WHEREAS, it is the express policy of the Corporation to indemnify its
directors so as to provide them with the maximum possible protection permitted
by law, and

     WHEREAS, Indemnitee does not regard the protection available under the
Corporation's Certificate of Incorporation and insurance as adequate in the
present circumstances, and may not be willing to serve or remain as a director
without adequate protection, and

     WHEREAS, the Corporation desires Indemnitee to serve, or continue to serve,
as a director of the Corporation.

     NOW THEREFORE, the Corporation and Indemnitee do hereby agree as follows:

     1.   Agreement to Serve.  Indemnitee agrees to serve or continue to serve
          ------------------
as a director of the Corporation for so long as he is duly elected or appointed
or until such time as he tenders his resignation in writing.

     2.   Definitions.  As used in this Agreement:
          -----------

          (a)  The term "Proceeding" shall include any threatened, pending or
completed action, suit, or proceeding, whether brought by or in the right of the
Corporation or otherwise and whether of a civil, criminal, administrative or
investigative nature, and any appeal therefrom.

          (b)  The term "Corporate Status" shall mean the status of a person who
is or was a director of the Corporation, or is or was serving, or has agreed to
serve, at the request of the Corporation, as a director, officer, partner,
trustee, employee or agent of another corporation, partnership, joint venture,

administrative proceedings or appeals, but shall not include the amount of
judgments, fines or penalties against Indemnitee or amounts paid in settlement
in connection with such matters.

          (d)  References to "other enterprise" shall include employee benefit
plans; references to "fines" shall include any excise tax assessed with respect
to any employee benefit plan; references to "serving at the request of the
Corporation" shall include any service as a director, officer, employee or agent

this Agreement.

     3.   Indemnification in Third-Party Proceedings.  The Corporation shall
          ------------------------------------------
indemnify Indemnitee in accordance with the provisions of this Paragraph 3 if
Indemnitee was or is a party to or threatened to be made a party to or otherwise
involved in any Proceeding (other than a Proceeding by or in the right of the
Corporation to procure a judgment in its favor) by reason of his Corporate
Status or by reason of any action alleged to have been taken or omitted in
connection therewith, against all Expenses, judgments, fines, penalties and
amounts paid in settlement actually and reasonably incurred by Indemnitee or on
his behalf in connection with such Proceeding, if Indemnitee acted in good faith
and in a manner which he reasonably believed to be in, or not opposed to, the
best interests of the Corporation and, with respect to any criminal Proceeding,
had no reasonable cause to believe that his conduct was unlawful.  The
termination of any Proceeding by judgment, order, settlement, conviction or upon
a plea of nolo contendere, or its equivalent, shall not, of itself, create a
          ---- ----------
presumption that Indemnitee did not act in good faith and in a manner which he
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, and, with respect to any criminal Proceeding, had reasonable cause

of any action alleged to have been taken or omitted in connection therewith,
against all Expenses and, to the extent permitted by law, amounts paid in
settlement actually and

                                      -2-
<PAGE>

reasonably incurred by Indemnitee or on his behalf in connection with such
Proceeding, if he acted in good faith and in a manner which he reasonably
believed to be in, or not opposed to, the best interests of the Corporation,
except that no indemnification shall be made under this Paragraph 4 in respect
of any claim, issue, or matter as to which Indemnitee shall have been adjudged
to be liable to the Corporation, unless and only to the extent that the Court of
Chancery of Delaware shall determine upon application that, despite the
adjudication of such liability but in view of all the circumstances of the case,
Indemnitee is fairly and reasonably entitled to indemnity for such Expenses as
the Court of Chancery shall deem proper.

     5.   Exceptions to Right of Indemnification.  Notwithstanding anything to
          --------------------------------------
the contrary in this Agreement, except as set forth in Paragraph 10, the
Corporation shall not indemnify the Indemnitee in connection with a Proceeding
(or part thereof) initiated by the Indemnitee unless the initiation thereof was
approved by the Board of Directors of the Corporation.  Notwithstanding anything
to the contrary in this Agreement, the Corporation shall not indemnify the
Indemnitee to the extent the Indemnitee is reimbursed from the proceeds of
insurance, and in the event the Corporation makes any indemnification payments
to the Indemnitee and the Indemnitee is subsequently reimbursed from the
proceeds of insurance, the Indemnitee shall promptly refund such indemnification
payments to the Corporation to the extent of such insurance reimbursement.

     6.   Indemnification of Expenses of Successful Party.  Notwithstanding any
          -----------------------------------------------
other provision of this Agreement, to the extent that Indemnitee has been
successful, on the merits or otherwise, in defense of any Proceeding or in
defense of any claim, issue or matter therein, Indemnitee shall be indemnified
against all Expenses incurred by him or on his behalf in connection therewith.
Without limiting the foregoing, if any Proceeding or any claim, issue or matter
therein is disposed of, on the merits or otherwise (including a disposition
without prejudice), without (i) the disposition being adverse to the Indemnitee,
(ii) an adjudication that the Indemnitee was liable to the Corporation, (iii) a
plea of guilty or nolo contendere by the Indemnitee, (iv) an adjudication that
                  ---------------
the Indemnitee did not act in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

     7.   Notification and Defense of Claim.  As a condition precedent to his
          ---------------------------------
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any Proceeding for which indemnity will or could be
sought by him and provide the Corporation with a copy of any summons, citation,
subpoena, complaint, indictment, information or other document relating to such
Proceeding with which he is served.  With respect to any Proceeding of which the
Corporation is

                                      -3-
<PAGE>

so notified, the Corporation will be entitled to participate therein at its own
expense and/or to assume the defense thereof at its own expense, with legal
counsel reasonably acceptable to the Indemnitee. After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such claim,
other than as provided below in this Paragraph 7. The Indemnitee shall have the
right to employ his own counsel in connection with such claim, but the fees and
expenses of such counsel incurred after notice from the Corporation of its
assumption of the defense thereof shall be at the expense of the Indemnitee
unless (i) the employment of counsel by the Indemnitee has been authorized by
the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded
that there may be a conflict of interest or position on any significant issue
between the Corporation and the Indemnitee in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of counsel for the Indemnitee shall be at the expense of the Corporation, except
as otherwise expressly provided by this Agreement. The Corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the Corporation or as to which counsel for
the Indemnitee shall have reasonably made the conclusion provided for in clause
(ii) above. The Corporation shall not be required to indemnify the Indemnitee
under this Agreement for any amounts paid in settlement of any Proceeding
effected without its written consent. The Corporation shall not settle any
Proceeding in any manner which would impose any penalty or limitation on
Indemnitee without Indemnitee's written consent. Neither the Corporation nor the
Indemnitee will unreasonably withhold their consent to any proposed settlement.

     8.   Advancement of Expenses.  Any Expenses incurred by the Indemnitee in
          -----------------------
connection with any such Proceeding to which the Indemnitee was or is a party or
is threatened to be a party by reason of his Corporate Status or by reason of
any action alleged to have been taken or omitted in connection therewith shall
be paid by the Corporation in advance of the final disposition of such matter;
provided, however, that the payment of such Expenses incurred by the Indemnitee
- --------  -------
in advance of the final disposition of such matter shall be made only upon
receipt of an undertaking by or on behalf of the Indemnitee to repay all amounts
so advanced in the event that it shall ultimately be determined that the
Indemnitee is not entitled to be indemnified by the Corporation as authorized in
this Agreement.  Such Expenses shall be paid immediately upon the written
request of the Indemnitee to the Corporation.

     9.   Procedure for Indemnification.  In order to obtain indemnification
          -----------------------------
pursuant to Paragraphs 3, 4 or 6 of this Agreement, Indemnitee shall submit to
the Corporation a written request, including in such request such documentation
and information as is reasonably available to Indemnitee and is reasonably
necessary to

                                      -4-
<PAGE>

determine whether and to what extent Indemnitee is entitled to indemnification
or advancement of Expenses. Any such indemnification shall be made promptly, and
in any event within 60 days after receipt by the Corporation of the written
request of the Indemnitee, unless with respect to requests under Paragraphs 3 or
4 the Corporation determines within such 60-day period that such Indemnitee did
not meet the applicable standard of conduct set forth in Paragraph 3 or 4, as
the case may be. Such determination, and any determination pursuant to Section 8
that advanced Expenses must be repaid to the Corporation, shall be made in each
instance (a) by a majority vote of the directors of the Corporation consisting
of persons who are not at that time parties to the Proceeding ("disinterested
directors"), whether or not a quorum, (b) by a committee of disinterested
directors designated by majority vote of disinterested directors, whether or not
a quorum, (c) if there are no disinterested directors, or if disinterested
directors so direct, by independent legal counsel (who may, to the extent
permitted by applicable law, be regular legal counsel to the Corporation) in a
written opinion, or (d) by the stockholders.

     10.  Remedies.  The right to indemnification and immediate advancement of
          --------
Expenses as provided by this Agreement shall be enforceable by the Indemnitee in
any court of competent jurisdiction.  Unless otherwise required by law, the
burden of proving that indemnification is not appropriate shall be on the
Corporation.  Neither the failure of the Corporation to have made a
determination prior to the commencement of such action that indemnification is
proper in the circumstances because Indemnitee has met the applicable standard
of conduct, nor an actual determination by the Corporation pursuant to Paragraph
9 that Indemnitee has not met such applicable standard of conduct, shall be a
defense to the action or create a presumption that Indemnitee has not met the
applicable standard of conduct. Indemnitee's expenses (of the type described in
the definition of "Expenses" in Paragraph 2(c)) reasonably incurred in
connection with successfully establishing his right to indemnification, in whole
or in part, in any such Proceeding shall also be indemnified by the Corporation.

     11.  Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------
provision of this Agreement to indemnification by the Corporation for some or a
portion of the Expenses, judgments, fines, penalties or amounts paid in
settlement actually and reasonably incurred by him or on his behalf in
connection with any Proceeding but not, however, for the total amount thereof,
the Corporation shall nevertheless indemnify Indemnitee for the portion of such
Expenses, judgments, fines, penalties or amounts paid in settlement to which
Indemnitee is entitled.

     12.  Subrogation.  In the event of any payment under this Agreement, the
          -----------
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnitee, who shall execute all papers required and take
all action necessary to secure such rights, including execution of such
documents as are necessary to enable the Corporation to bring suit to enforce
such rights.

                                      -5-
<PAGE>

     13.  Term of Agreement.  This Agreement shall continue until and terminate
          -----------------
upon the later of (a) six years after the date that Indemnitee shall have ceased
to serve as a director of the Corporation or, at the request of the Corporation,
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise or (b) the final termination of all
Proceedings pending on the date set forth in clause (a) in respect of which
Indemnitee is granted rights of indemnification or advancement of Expenses
hereunder and of any proceeding commenced by Indemnitee pursuant to Paragraph 10
of this Agreement relating thereto.

     14.  Indemnification Hereunder Not Exclusive.  The indemnification and
          ---------------------------------------
advancement of Expenses provided by this Agreement shall not be deemed exclusive
of any other rights to which Indemnitee may be entitled under the Certification
of Incorporation, the By-Laws, any agreement, any vote of stockholders or
disinterested directors, the General Corporation Law of Delaware, any other law
(common or statutory), or otherwise, both as to action in his official capacity
and as to action in another capacity while holding office for the Corporation.
Nothing contained in this Agreement shall be deemed to prohibit the Corporation
from purchasing and maintaining insurance, at its expense, to protect itself or
the Indemnitee against any expense, liability or loss incurred by it or him in
any such capacity, or arising out of his status as such, whether or not the
Indemnitee would be indemnified against such expense, liability or loss under
this Agreement; provided that the Corporation shall not be liable under this
Agreement to make any payment of amounts otherwise indemnifiable hereunder if
and to the extent that Indemnitee has otherwise actually received such payment
under any insurance policy, contract, agreement or otherwise.

     15.  No Special Rights.  Nothing herein shall confer upon Indemnitee any
          -----------------
right to continue to serve as a director of the Corporation for any period of
time or at any particular rate of compensation.

     16.  Savings Clause.  If this Agreement or any portion thereof shall be
          --------------
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify Indemnitee as to Expenses, judgments,
fines, penalties and amounts paid in settlement with respect to any Proceeding
to the full extent permitted by any applicable portion of this Agreement that
shall not have been invalidated and to the fullest extent permitted by
applicable law.

     17.  Counterparts.  This Agreement may be executed in any number of
          ------------
counterparts, each of which shall constitute the original.

     18.  Successors and Assigns.  This Agreement shall be binding upon the
          ----------------------
Corporation and its successors and assigns and shall inure to the benefit of the
estate, heirs, executors, administrators and personal representatives of
Indemnitee.

                                      -6-
<PAGE>

     19.  Headings.  The headings of the paragraphs of this Agreement are
          --------
inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction thereof.

     20.  Modification and Waiver.  This Agreement may be amended from time to
          -----------------------
time to reflect changes in Delaware law or for other reasons.  No supplement,
modification or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto.  No waiver of any of the provisions of
this Agreement shall be deemed or shall constitute a waiver of any other
provision hereof nor shall any such waiver constitute a continuing waiver.

     21.  Notices.  All notices, requests, demands and other communications
          -------
hereunder shall be in writing and shall be deemed to have been given (i) when
delivered by hand or (ii) if mailed by certified or registered mail with postage
prepaid, on the third day after the date on which it is so mailed:

          (a)  if to the Indemnitee, to:

               ______________________
               ______________________
               ______________________

          (b)  if to the Corporation, to:

               Andover, Massachusetts  01810
               Attn:  Paul L. Schaut, President

or to such other address as may have been furnished to Indemnitee by the
Corporation or to the Corporation by Indemnitee, as the case may be.

     22.  Applicable Law.  This Agreement shall be governed by and construed in
          --------------
accordance with the laws of the State of Delaware.

     23.  Enforcement.  The Corporation expressly confirms and agrees that it
          -----------
has entered into this Agreement in order to induce Indemnitee to continue to
serve as a director of the Corporation, and acknowledges that Indemnitee is
relying upon this Agreement in continuing in such capacity.

     2.   Registration Rights
          -------------------

          2.1  Required Registrations.
               ----------------------

               (a)  At any time following 180 days after the closing of the
Initial Public Offering, a Stockholder or Stockholders may request, in writing,
that the Company effect the registration on Form S-1 or Form S-2 (or any
successor form) of Registrable Shares owned by such Stockholder or Stockholders
having an aggregate value of at least $10,000,000 (based on the then current
public market price).

               (b)  At any time after the Company becomes eligible to file a
Registration Statement on Form S-3 (or any successor form relating to secondary
offerings), a Stockholder or Stockholders may request, in writing, that the
Company effect the registration on Form S-3 (or such successor form), of
Registrable Shares having an aggregate value of at least $2,500,000 (based on
the then current public market price).

               (c)  Upon receipt of any request for registration pursuant to
this Section 2, the Company shall promptly give written notice of such proposed
registration to all other Stockholders. Such Stockholders shall have the right,
by giving written notice to the Company within 15 days after the Company
provides its notice, to elect to have included in such registration such of
their Registrable Shares as such Stockholders may request in such notice of
election, subject in the case of an underwritten offering to the approval of the
managing underwriter as provided in Section 2.1(d) below. Thereupon, the Company
shall, as expeditiously as possible, use its best efforts to effect the
registration on an appropriate registration form of all Registrable Shares which
the Company has been requested to so register (provided, however, that in the
case of a registration requested under Section 2.1(b), the Company will only be
obligated to effect such registration on Form S-3 (or any successor form)).

               (d)  If the Initiating Holders intend to distribute the
Registrable Shares covered by their request by means of an underwriting, they
shall so advise the Company as a part of their request made pursuant to Section
2.1(a) or (b), as the case may be, and the Company shall include such
information in its written notice referred to in Section 2.1(c). The right of
any other Stockholder to include its Registrable Shares in such registration
pursuant to Section 2.1(a) or (b), as the case may be, shall be conditioned upon
such other Stockholder's participation in such underwriting on the terms set
forth herein. If the managing underwriter determines that the marketing factors
require a limitation of the number of shares to be underwritten, the number of
Registrable Shares to be included in a Registration Statement filed pursuant to
this Section 2.1, shall be reduced pro rata among the requesting Stockholders
based on the quotient of (1) the total Registrable Shares to be included in the
Registration Statement, divided by (2) the total number of Registrable Shares
that requested registration.

                                      -3-
<PAGE>

               (e)  The Initiating Holders shall have the right to select the
managing underwriter(s) for any underwritten offering requested pursuant to
Section 2.1(a) or (b), subject to the approval of the Company, which approval
will not be unreasonably withheld.

               (f)  The Company shall not be required to effect more than two
registrations pursuant to Section 2.1(a) or more than five registrations
pursuant to Section 2.1(b).  In addition, the Company shall not be required to
effect any registration within 90 days after the effective date of any other
Registration Statement of the Company relating to an underwritten offering.  For
purposes of this Section 2.1(f), a Registration Statement shall not be counted
until such time as such Registration Statement has been declared effective by
the Commission (unless the Initiating Holders withdraw their request for such
registration (other than as a result of information concerning the business or
financial condition of the Company which is made known to the Stockholders after
the date on which such registration was requested) and elect not to pay the
Registration Expenses therefor pursuant to Section 2.4).

               (g)  If at the time of any request to register Registrable Shares
by Initiating Holders pursuant to this Section 2.1, the Company is engaged or
has plans to engage in a registered public offering or is engaged in any other
activity which, in the good faith determination of the Company's Board of
Directors, would be adversely affected by the requested registration or
financial statements required for the requested registration are not then
available, then the Company may at its option direct that such request be
delayed for a period not in excess of 90 days from the date of such request,
such right to delay a request to be exercised by the Company not more than once
in any 12-month period.

          2.2  Incidental Registration.
               -----------------------

               (a)  Whenever the Company proposes to file a Registration
Statement (other than a Registration Statement filed pursuant to Section 2.1) at
any time and from time to time, it will, prior to such filing, give written
notice to all Stockholders of its intention to do so; provided, that no such
                                                      --------
notice need be given if no Registrable Shares are to be included therein as a
result of a determination of the managing underwriter pursuant to Section
2.2(b). Upon the written request of a Stockholder or Stockholders given within
20 days after the Company provides such notice (which request shall state the
intended method of disposition of such Registrable Shares), the Company shall
use its best efforts to cause all Registrable Shares which the Company has been
requested by such Stockholder or Stockholders to register to be registered under
the Securities Act to the extent necessary to permit

                                      -4-
<PAGE>

their sale or other disposition in accordance with the intended methods of
distribution specified in the request of such Stockholder or Stockholders;
provided that the Company shall have the right to postpone or withdraw any
registration effected pursuant to this Section 2.2 without obligation to any
Stockholder.

               (b)  If the registration for which the Company gives notice
pursuant to Section 2.2(a) involves an underwriting, the Company shall so advise
the Stockholders as a part of the written notice given pursuant to Section
2.2(a). In such event, the right of any Stockholder to include its Registrable
Shares in such registration pursuant to Section 2.2 shall be conditioned upon
such Stockholder's participation in such underwriting on the terms set forth
herein. All Stockholders proposing to distribute their securities through such
underwriting shall enter into an underwriting agreement in customary form with
the underwriter or underwriters selected for the underwriting by the Company.
Notwithstanding any other provision of this Section 2.2, if the managing
underwriter determines that the inclusion of all shares requested to be
registered would adversely affect the offering, the Company may limit the number
of Registrable Shares to be included in the registration and underwriting. The
Company shall so advise all holders of Registrable Shares requesting
registration, and the number of shares that are entitled to be included in the
registration and underwriting shall be allocated in the following manner. The
securities of the Company held by holders other than Stockholders and other
stockholders entitled to include shares therein ("Other Holders") shall be
excluded from such registration and underwriting to the extent deemed advisable
by the managing underwriter, and, if a further limitation on the number of
shares is required, the number of shares that may be included in such
registration and underwriting shall be allocated among all Stockholders and
Other Holders requesting registration in proportion, as nearly as practicable,
to the respective number of shares of Common Stock which they held at the time
the Company gives the notice specified in Section 2.2(a). If any Stockholder or
Other Holder would thus be entitled to include more securities than such holder
requested to be registered, the excess shall be allocated among other requesting
Stockholders and Other Holders pro rata in the manner described in the preceding
sentence. If any holder of Registrable Shares or any Other Holder disapproves of
the terms of any such underwriting, such person may elect to withdraw therefrom
by written notice to the Company, and any Registrable Shares or other securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration.

               (c)  Notwithstanding the foregoing, the Company shall not be
required, pursuant to this Section 2.2, to include any Registrable Shares in a
Registration Statement if such Registrable Shares can then be sold pursuant to
Rule 144(k) under the Securities Act and represent less than 1% of the then
outstanding shares of Common Stock.

                                      -5-

          2.3  Registration Procedures.
               -----------------------

               (a)  If and whenever the Company is required by the provisions of
this Agreement to use its best efforts to effect the registration of any
Registrable Shares under the Securities Act, the Company shall:

                    (i)    file with the Commission a Registration Statement
with respect to such Registrable Shares and use its best efforts to cause that
Registration Statement to become effective as soon as possible;

                    (ii)   as expeditiously as possible prepare and file with
the Commission any amendments and supplements to the Registration Statement and
the prospectus included in the Registration Statement as may be necessary to
comply with the provisions of the Securities Act (including the anti-fraud
provisions thereof) and to keep the Registration Statement effective for 12
months from the effective date or such lesser period until all such Registrable
Shares are sold;

                    (iii)  as expeditiously as possible furnish to each Selling
Stockholder such reasonable numbers of copies of the Prospectus, including any
preliminary Prospectus, in conformity with the requirements of the Securities
Act, and such other documents as such Selling Stockholder may reasonably request
in order to facilitate the public sale or other disposition of the Registrable
Shares owned by such Selling Stockholder;

                    (iv)   as expeditiously as possible use its best efforts to
register or qualify the Registrable Shares covered by the Registration Statement
under the securities or Blue Sky laws of such states as the Selling Stockholders
shall reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the Selling Stockholders to consummate the
public sale or other disposition in such states of the Registrable Shares owned
by the Selling Stockholder; provided, however, that the Company shall not be
                            --------  -------
required in connection with this paragraph (iv) to qualify as a foreign
corporation or execute a general consent to service of process in any
jurisdiction;

                    (v)    as expeditiously as possible, cause all such
Registrable Shares to be listed on each securities exchange or automated
quotation system on which similar securities issued by the Company are then
listed; and

                    (vi)   promptly make available for inspection by the Selling
Stockholders, any managing underwriter participating in any disposition pursuant
to such Registration Statement, and any attorney or accountant or other agent
retained by any such underwriter or selected by the Selling Stockholders, all
financial and other records, pertinent corporate documents and properties of the
Company and cause the Company's officers, directors, employees and independent

                                      -6-
<PAGE>

accountants to supply all information reasonably requested by any such seller,
underwriter, attorney, accountant or agent in connection with such Registration
Statement.

               (b)  If the Company has delivered a Prospectus to the Selling
Stockholders and after having done so the Prospectus is amended to comply with
the requirements of the Securities Act, the Company shall promptly notify the
Selling Stockholders and, if requested, the Selling Stockholders shall
immediately cease making offers of Registrable Shares and return all
Prospectuses to the Company. The Company shall promptly provide the Selling
Stockholders with revised Prospectuses and, following receipt of the revised
Prospectuses, the Selling Stockholders shall be free to resume making offers of
the Registrable Shares.

               (c)  In the event that, in the judgment of the Company, it is
advisable to suspend use of a Prospectus included in a Registration Statement
due to pending material developments or other events that have not yet been
publicly disclosed and as to which the Company believes public disclosure would
be detrimental to the Company, the Company shall notify all Selling Stockholders
to such effect, and, upon receipt of such notice, each such Selling Stockholder
shall immediately discontinue any sales of Registrable Shares pursuant to such
Registration Statement until such Selling Stockholder has received copies of a
supplemented or amended Prospectus or until such Selling Stockholder is advised
in writing by the Company that the then current Prospectus may be used and has
received copies of any additional or supplemental filings that are incorporated
or deemed incorporated by reference in such Prospectus. Notwithstanding anything
to the contrary herein, the Company shall not exercise its rights under this
Section 2.3(c) to suspend sales of Registrable Shares for a period in excess of
90 days in any 365-day period.

          2.4  Allocation of Expenses.  The Company will pay all Registration
               ----------------------
Expenses for all registrations under this Agreement; provided, however, that if
                                                     --------  -------
a registration under Section 2.1 is withdrawn at the request of the Initiating
Holders (other than as a result of information concerning the business or
financial condition of the Company which is made known to the Stockholders after
the date on which such registration was requested) and if the Initiating Holders
elect not to have such registration counted as a registration requested under
Section 2.1, the requesting Stockholders shall pay the Registration Expenses of
such registration pro rata in accordance with the number of their Registrable
Shares included in such registration. For purposes of this Section, the term
"Registration Expenses" shall mean all expenses incurred by the Company in
complying with this Agreement, including, without limitation, all registration
and filing fees, exchange listing fees, printing expenses, fees and expenses of
counsel for the Company and the fees and expenses of one counsel selected by the
Selling Stockholders to represent the Selling Stockholders, state Blue Sky fees
and expenses, and the expense of any special audits incident to or required by
any such registration, but excluding underwriting discounts, selling commissions
and the fees and expenses of Selling Stockholders' own counsel (other than the
counsel selected to represent all Selling Stockholders).

          2.5  Indemnification and Contribution.
               --------------------------------

               (a)  In the event of any registration of any of the Registrable
Shares under the Securities Act pursuant to this Agreement, the Company will
indemnify and hold harmless the seller of such Registrable Shares, each
underwriter of such Registrable Shares, and each other person, if any, who
controls such seller or underwriter within the meaning of the Securities Act or
the Exchange Act against any losses, claims, damages or liabilities, joint or
several, to which such seller, underwriter or controlling person may become
subject under the Securities Act, the Exchange Act, state securities or Blue Sky
laws or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in any Registration
Statement under which such Registrable Shares were registered under the
Securities Act, any preliminary prospectus or final prospectus contained in the
Registration Statement, or any amendment or supplement to such Registration
Statement, or arise out of or are based upon the omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and the Company will reimburse such seller,
underwriter and each such controlling person for any legal or any other expenses
reasonably incurred by such seller, underwriter or controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
                     --------  -------
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any untrue statement or omission made in such
Registration Statement, preliminary prospectus or prospectus, or any such
amendment or supplement, in reliance upon and in conformity with information
furnished to the Company, in writing, by or on behalf of such seller,
underwriter or controlling person specifically for use in the preparation
thereof.

               (b)  In the event of any registration of any of the Registrable
Shares under the Securities Act pursuant to this Agreement, each seller of
Registrable Shares, severally and not jointly, will indemnify and hold harmless
the Company, each of its directors and officers and each underwriter (if any)
and each person, if any, who controls the Company or any such underwriter within
the meaning of the Securities Act or the Exchange Act, against any losses,
claims, damages or liabilities, joint or several, to which the Company, such
directors and officers, underwriter or controlling person may become subject
under the Securities Act, Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in any Registration

                                      -8-
<PAGE>

Statement under which such Registrable Shares were registered under the
Securities Act, any preliminary prospectus or final prospectus contained in the
Registration Statement, or any amendment or supplement to the Registration
Statement, or arise out of or are based upon any omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, if the statement or omission was made in
reliance upon and in conformity with information relating to such seller
furnished in writing to the Company by or on behalf of such seller specifically
for use in connection with the preparation of such Registration Statement,
prospectus, amendment or supplement; provided, however, that the obligations of
                                     --------  -------
a Stockholder hereunder shall be limited to an amount equal to the net proceeds
to such Stockholder of Registrable Shares sold in connection with such
registration.

               (c)  Each party entitled to indemnification under this Section
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided, that counsel for the Indemnifying
                                --------
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld); and, provided, further, that the failure of any Indemnified Party to
                --------  -------
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section except to the extent that the Indemnifying Party
is adversely affected by such failure. The Indemnified Party may participate in
such defense at such party's expense; provided, however, that the Indemnifying
                                      --------  -------
Party shall pay such expense if representation of such Indemnified Party by the
counsel retained by the Indemnifying Party would be inappropriate due to actual
or potential differing interests between the Indemnified Party and any other
party represented by such counsel in such proceeding; provided further that in
                                                      -------- -------
no event shall the Indemnifying Party be required to pay the expenses of more
than one law firm per jurisdiction as counsel for the Indemnified Party.  The
Indemnifying Party also shall be responsible for the expenses of such defense if
the Indemnifying Party does not elect to assume such defense.  No Indemnifying
Party, in the defense of any such claim or litigation shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect of such claim or litigation, and no Indemnified Party
shall consent to entry of any judgment or settle such claim or litigation
without the prior written consent of the Indemnifying Party, which consent shall
not be unreasonably withheld.

               (d)  In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in this Section 2.5 is
due in accordance with its terms but for any reason is held to be unavailable to
an Indemnified Party in respect to any losses, claims, damages and liabilities
referred to herein, then the Indemnifying Party shall, in lieu of indemnifying
such Indemnified

                                      -9-
<PAGE>

Party, contribute to the amount paid or payable by such Indemnified Party as a
result of such losses, claims, damages or liabilities to which such party may be
subject in such proportion as is appropriate to reflect the relative fault of
the Company on the one hand and the Stockholders on the other in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative fault of the Company and the Stockholders shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of material fact related to information supplied by the Company or the
Stockholders and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Company
and the Stockholders agree that it would not be just and equitable if
contribution pursuant to this Section 2.5 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph of Section 2.5, (a) in no case shall any one Stockholder be
liable or responsible for any amount in excess of the net proceeds received by
such Stockholder from the offering of Registrable Shares and (b) the Company
shall be liable and responsible for any amount in excess of such proceeds;
provided, however, that no person guilty of fraudulent misrepresentation (within
- --------  -------
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  Any party entitled to contribution will, promptly after
receipt of notice of commencement of any action, suit or proceeding against such
party in respect of which a claim for contribution may be made against another
party or parties under this Section, notify such party or parties from whom
contribution may be sought, but the omission so to notify such party or parties
from whom contribution may be sought shall not relieve such party from any other
obligation it or they may have thereunder or otherwise under this Section.  No
party shall be liable for contribution with respect to any action, suit,
proceeding or claim settled without its prior written consent, which consent
shall not be unreasonably withheld.

          2.6  Other Matters with Respect to Underwritten Offerings.  In the
               ----------------------------------------------------
event that Registrable Shares are sold pursuant to a Registration Statement in
an underwritten offering pursuant to Section 2.1, the Company agrees to enter
into an underwriting agreement containing customary representations and
warranties with respect to the business and operations of the Company and
customary covenants and agreements to be performed by the Company, including
without limitation customary provisions with respect to indemnification by the
Company of the underwriters of such offering.

          2.7  Information by Holder.  Each holder of Registrable Shares
               ---------------------
included in any registration shall furnish to the Company such information
regarding such holder and the distribution proposed by such holder as the
Company may reasonably request in writing and as shall be required in connection
with any registration, qualification or compliance referred to in this
Agreement.

     3.   Right Of First Refusal
          ----------------------

          3.1  Rights of Investor
               ------------------

               (a)  Until the first date on which the Investor or any Permitted
Transferee (as defined below) owns less than a majority, by voting power, of the
outstanding shares of capital stock of the Company (assuming the exercise and
conversion of all outstanding options, warrants and convertible securities), the
Company shall not issue or sell (i) any shares of its Common Stock, (ii) any
other voting equity securities of the Company, including, without limitation,
shares of preferred stock, (iii) any option, warrant or other right to subscribe
for, purchase or otherwise acquire any voting equity securities of the Company,
or (iv) any debt securities convertible into voting capital stock of the Company
(collectively, the "Offered Securities"), unless in each such case the Company
shall have first complied with this Section 3.1.  The Company shall deliver to
the Investor a written notice of any proposed or intended issuance or sale of
Offered Securities (the "Offer"), which Offer shall (i) identify and describe
the Offered Securities, (ii) describe the price and other terms upon which they
are to be issued or sold, and the number or amount of the Offered Securities to
be issued or sold, (iii) identify the persons or entities (if known) to which or
with which the Offered Securities are to be offered, issued or sold and (iv)
offer to issue and sell to the Investor a number of the Offered Securities (the
"Available Amount") such that, after the issuance and sale of all of the Offered
Securities, including the purchase of the Available Amount by the Investor, the
Investor would own at least a majority, by voting power, of the outstanding
capital stock of the Company (assuming the exercise and conversion of all
outstanding options, warrants and convertible securities).  The Company shall
not be required to offer any Offered Securities to the Investor hereunder if,
after the issuance and sale thereof, the Investor (or the Permitted Transferee)
would continue to own at least a majority, by voting power, of the outstanding
capital stock of the Company (assuming the exercise and conversion of all
outstanding options, warrants and convertible securities).

               (b)  To accept an Offer, in whole or in part, the Investor must
deliver a written notice to the Company within 20 days after its receipt of the
Offer, setting forth the portion of the Available Amount that the Investor
elects to purchase (the "Notice of Acceptance").

               (c)  The Company shall have 180 days from the expiration of the
period set forth in Section 3.1(b) above to issue or sell all or any part of
such Offered Securities as to which a Notice of Acceptance has not been given by
the Investor, upon terms and conditions which are not more favorable, in the
aggregate, to the acquiring person or persons or less favorable to the Company
than those set forth in the Offer. If the consideration to be received by the
Company from the sale of Offered Securities consists of anything other than
cash, the Board of Directors of

                                      -11-
<PAGE>

the Company shall in good faith determine the cash equivalent of such non-cash
consideration and the Investor may pay an equivalent portion of its purchase
price for the Offered Securities in cash.

               (d)  The purchase by the Investor of any Offered Securities is
subject in all cases to the preparation, execution and delivery by the Company
and the Investor of a purchase agreement relating to such Offered Securities
reasonably satisfactory in form and substance to the Investor.

               (e)  The rights of the Investor under this Section 3 shall not
apply to the grant of options to officers, directors, consultants and employees
of the Company or any subsidiary pursuant to any plan, agreement or arrangement
approved by a vote of not less than a majority of the members of the Board of
Directors of the Company, provided, however, that if the exercise of any such
                          --------
options results in the reduction of the Investor's, or Permitted Transferee's,
ownership to less than a majority, by voting power, of the outstanding capital
stock of the Company, the Company shall so notify the Investor (or Permitted
Transferee), and the Investor or Permitted Transferee shall have the right,
within 30 days after such notice, to purchase from the Company, at a price equal
to the then Fair Market Value (as defined below) thereof, such number of shares
of Common Stock as would increase its ownership to a majority, by voting power,
of the outstanding capital stock of the Company.  "Fair Market Value" shall mean
the average closing price of the Common Stock, on the NASDAQ National Market (or
other principal securities exchange on which the Common Stock is traded), during
the 10-day period ending on the day prior to the date of purchase.

          3.2  Termination.  This Section 3 shall terminate upon the earlier of
               -----------
(i) the sale of all or substantially all of the assets or business of the
Company, by merger, sale of assets or otherwise, and (ii) the first date on
which the Investor (or Permitted Transferee) owns less than a majority, by
voting power, of the outstanding capital stock of the Company for 30 consecutive
days.

          3.3  Permitted Transferee.  For purposes hereof, a "Permitted
               --------------------
Transferee" shall mean any person or entity that acquires directly from the
Investor shares of Common Stock representing at least a majority of the
outstanding shares of Common Stock of the Company and to which the Investor
assigns, in writing, its rights under this Section 3.  Upon such assignment, the
Permitted Transferee shall be considered the "Investor" for purposes of Section
3 of this Agreement.

     4.   Transfers of Rights.  The rights and obligations of the Investor under
          -------------------
Section 2 may be assigned by to any person or entity that requires at least
$2,500,000 shares of Common Stock (as adjusted in stock splits and similar
events) from the Investor.  The rights and obligations of the Investor under
Section 3 may be assigned only to a Permitted Transferee, and, upon such
assignment, the rights and obligations

                                      -12-
<PAGE>

of the Investor under Section 3 shall terminate. In the event of any such
transfer, the transferee must provide written notice of such assignment to the
Company and agree in writing to be bound by the applicable provisions of this
Agreement.

     5.   General.
          -------

          (a)  Severability.  The invalidity or unenforceability of any

3.   It is specifically understood and agreed that during the term of this

copyright or susceptible to other forms of protection, that relate to the actual
or anticipated business or research or development of Engage; or, are suggested
by or result from any task assigned or work performed by Consultant for or on
behalf of Engage.  Consultant acknowledges that the copyrights in Developments
created in the scope of performance of this Agreement, belong to Engage by

on the request of Engage, to promptly execute separate written assignments to
Engage and do all things reasonably necessary to enable Engage to secure
patents, register copyrights or obtain any other forms of protection for
Developments in the United States and in other countries, at Consultant's usual
rate of compensation plus required expenses.  In the event Engage is unable,
after sending notice by certified mail with return receipt requested to the
address of Consultant on page 1 of this Agreement or other address supplied by
Consultant in writing to Engage, to secure Consultant's authorized signature on
any letters patent, copyright or other analogous protection relating to a
Development, for any reason whatsoever, Consultant hereby designates and
appoints Engage and its duly authorized officers and agents as Consultant's
agent and attorney-in-fact, to act for and in Consultant's behalf to execute and

<PAGE>

9.   Engage, its subsidiaries, licensees, successors and assigns (direct or
indirect), are not required to designate Consultant as the Inventor, creator or
author of any Development, when such Development is distributed publicly or
otherwise.  Consultant waives and releases, to the extent permitted by law, all
rights to such designation and any rights concerning future modifications of
such Developments.

10.  Consultant understands that this Agreement does not create an obligation on
Engage or any other person to continue Consultant's engagement.

11.  Rights and assignments granted by Consultant in this Agreement are
assignable by Engage and are for the benefit of the successors and assigns of
Engage.  Consultant shall not assign this Agreement or any rights under this
Agreement.  Consultant's obligations under this Agreement shall survive the
termination of Consultant's engagement by Engage regardless of the manner of
such termination and shall be binding upon Consultant's successors in interest
or other legal representatives.

12.  Consultant acknowledges that any breach of its obligations under this
Agreement may result in irreparable injury to Engage.  Engage may, therefore, be
entitled, without restricting Engage from other legal and equitable remedies, to
injunctive and other equitable relief to prevent or restrain the breach of this
Agreement.

13.  Consultant hereby acknowledges that Engage is now and may hereafter be
subject to non-disclosure or confidentiality agreements with third persons
pursuant to which Engage must protect or refrain from use of proprietary
information which is the property of such third persons.  Consultant hereby
agrees upon the directive of Engage to be bound by the terms of such agreements
in the event Consultant has access to the proprietary information protected
thereunder to the same extent as if Consultant was an original signatory
thereto.

14.  No delay or omission by either party in exercising any right under this
Agreement will operate as a waiver of that or any other right; a waiver or
consent given by a party on any one occasion is effective only in that instance
and will not be construed as a bar to or waiver of any right on any other
occasion.

15.  With respect to the subject matter hereof, this Agreement, including
Schedules A and B attached hereto, supersedes all previous oral or written
communications, representations, understandings, undertakings, or agreements by
or with Engage and this Agreement can only be amended by a writing signed by
both parties; provided that, subject to Section 6 of this Agreement, this
Agreement shall not supersede the Nondisclosure, Noncompetition and Inventions
Agreement entered into between CMG Information Services, Inc. and Chris Evans
dated April 8, 1998.

16.  In the event any paragraph or provision of this Agreement shall be held to
be illegal or unenforceable, such paragraph or provision shall be severed from
this Agreement and the entire Agreement shall not fail on account thereof, but
shall otherwise remain in full force and effect.  This Agreement may be signed
in two or more counterparts, each of which shall be deemed an original and all
of which shall together constitute one agreement.

17.  This Agreement shall be governed by the laws of the Commonwealth of
Massachusetts, without regard to its conflict of laws provisions.

     WHEREAS, Engage wishes to merge a corporation formed and incorporated in
Delaware and wholly owned by Engage with I/PRO in accordance with California
law, in which I/PRO will be the surviving company and wholly owned by Engage and
in which the remaining stockholders of I/PRO will receive cash compensation (the
"Merger"); and

     WHEREAS, CMGI will hold over 80% of the capital stock of Engage on a fully
diluted, as converted basis after consummation of the transactions contemplated
by this Inter-Company Agreement.

     NOW, THEREFORE, in consideration of the mutual promises, covenants and
conditions hereinafter set forth and other good and valuable consideration, the
parties hereto hereby agree as follows:

     1.   Upon the terms and subject to the conditions of this Inter-Company
Agreement (the "Agreement"), CMGI hereby agrees to contribute to Engage, and
Engage hereby agrees to accept from CMGI, all shares of I/PRO common stock, par
value $0.001 per share, (the "I/PRO Stock") purchased by CMGI on April 7, 1999,
pursuant to Section 1.1(b) of the Purchase Agreement (purchased by CMGI in
return for 180,266 shares of CMGI Common Stock disbursed by CMGI to Stockholders
as part of the Initial Consideration as provided therein). In consideration for
such I/PRO Stock, and for CMGI's cash payments of (a) $1,160,000 distributed
pursuant to Section 7.3 of the Purchase Agreement and (b) $27.13 distributed for
fractional shares; and (c) $612,838.08 distributed to unaccredited shareholders
and as part of the squeezeout merger (less $112,498.50 received back by CMGI as
the exercise price of the Comdisco warrant) and all as set forth in the
Breakdown of the Initial IPRO Price hereby certified by Engage to be true and
correct and attached hereto as Exhibit B, Engage hereby agrees to issue to CMGI
218,460 shares of Series C Preferred Stock of Engage valued at $101.10 per share
with an Applicable Purchase Price of $ 101.10 per share, and initially
convertible into 2,184,600 shares of Engage Common Stock. Such Series C
Preferred Stock shall have the rights and privileges as are set forth in the
form of Certificate of Designations attached hereto as Exhibit C. In the event
CMGI is required to pay any additional amounts in connection with the initial
acquisition of
<PAGE>

I/PRO (exclusive of Contingent Consideration or amounts paid in connection with
any claimed breach of Section 4 of the Purchase Agreement) whether in connection
with appraisal rights or additional payments to unaccredited investors or in
connection with the squeezeout merger or otherwise, then Engage shall
immediately reimburse CMGI for any and all such payments by paying CMGI, at
CMGI's sole option, cash in the amount of such payments or by issuing to CMGI
additional shares of Engage Series C Preferred Stock and valued for purposes of
this calculation at $101.10 per share with an Applicable Purchase Price of $
101.10 per share (or following a Qualified Public Offering by issuing to CMGI
shares of Engage Common Stock into which said shares of Series C Preferred Stock
would have been converted upon such Qualified Public offering valued for
purposes of this calculation at $ 10.11 per share). Sums payable out of the
Escrow to the Purchasers shall be paid entirely to Engage.

     2.   The transactions contemplated by Section 1 of this Inter-Company
Agreement shall for purposes of this Agreement be deemed to have taken place on
April 7, 1999, the closing date of the I/PRO acquisition.

     3.   Any amounts paid by CMGI pursuant to the Purchase Agreement in
connection with the payment of Contingent Consideration shall be paid by CMGI in
cash or CMGI common stock, as applicable. Engage shall immediately reimburse
CMGI for any and all such payments by paying CMGI, at CMGI's sole option, cash
in the amount of such payments or by issuing to CMGI additional shares of Engage
Series C Preferred Stock valued for purposes of this calculation with reference
to the total enterprise valuation of Engage as of the end of the immediately
preceding fiscal quarter (as determined by the Board of Directors of Engage in
good faith and in a manner consistent with past practice and satisfactory to
CMGI in all respects) (or following a Qualified Public Offering by issuing to
CMGI shares of Engage Common Stock valued at the average closing price of such
stock during the 20 trading days ending on the third trading day prior to the
date of issuance). All CMGI Common Stock shall be valued in accordance with
Section 1.1 (b)(vii) of the Purchase Agreement.

     4.   Attached hereto as Exhibit D is the capitalization table of Engage as
of the date hereof, after giving effect to the initial acquisition transactions
contemplated by the Purchase Agreement.

     5.   As between CMGI and Engage, any liability arising from a breach of any
representation in Section 4 of the Purchase Agreement relating to CMGI shall be
the responsibility of CMGI, and any liability arising from a breach of any
representation in Section 4 relating to Engage shall be the responsibility of
Engage.

     6.   The purpose of this Agreement is to provide for the equitable
adjustment of amounts due Engage and CMGI with respect to the acquisition of

                                      -2-

I/PRO by Engage as set forth above and shall not under any circumstances be
deemed to create any rights in, or confer any benefits upon, any third party or
parties (including, without limitation, the former stockholders of I/PRO) in any
respect. Nothing herein shall be construed as waiving or affecting any
respective rights of the Purchasers with respect to any amounts held in escrow
or with respect to any amounts due from the Stockholders or with respect to any
indemnification obligations or otherwise. Capitalized terms used herein which
are defined in the Purchase Agreement have the same meanings herein as therein,
except to the extent that such meanings are amended hereby.

     IN WITNESS WHEREOF, the parties have executed this Inter-Company Agreement
as of the date first above written.

subsequent to providing the estimate of 7.3 expenses to us). Under the terms of
the Stock Purchase Agreement, any difference between actual and assumed
obligations is to be refunded to stockholders. The above assumes that CMGI will
need to refund $24,732 to the IPRO shareholders, presumably into escrow.

     Engage Technologies, Inc., a Delaware corporation (the "Company"), pursuant
to authority conferred on the Board of Directors of the Company by the
Certificate of Incorporation of the Company, as amended to date, and in
accordance with the provisions of Section 151 of the General Corporation Law of
the State of Delaware, certifies that the Board of Directors of the Company, at
a meeting duly held on May 5, 1999, has duly adopted the following resolution
providing for the establishment and issuance of a series of Preferred Stock to
be designated "Series C Convertible Preferred Stock" and to consist of two
million (2,000,000) shares as follows:

     RESOLVED: That, pursuant to the authority expressly granted and vested in
               the Board of Directors of the Company in accordance with the
               provisions of Section 151 of the General Corporation Law of the
               State of Delaware and its Amended and Restated Certificate of
               Incorporation, a series of Preferred Stock of the Company hereby
               is established, consisting of two million (2,000,000) shares to
               be designated "Series C Convertible Preferred Stock" (hereinafter
               "Series C Preferred Stock"); the Board of Directors be and hereby
               is authorized to issue such shares of Series C Preferred Stock
               from time to time and for such consideration and on such terms as
               the Board of Directors shall determine; and subject to the
               limitations provided by law and by the Amended and Restated
               Certificate of Incorporation, the powers, designations,
               preferences and relative, participating, optional or other
               special rights of, and the qualifications, limitations or
               restrictions upon, the Series C Preferred Stock shall be as
               follows:

     1.   Designation.  This series of Preferred Stock, par value $0.01 per
          -----------
share, shall be designated the "Series C Convertible Preferred Stock"
(hereinafter "Series C Preferred Stock").

     2.   Dividends.
          ---------

          (a) The holders of shares of Series C Preferred Stock shall be
entitled to receive, out of funds legally available therefor, dividends computed
at a rate of 7% of the Applicable Purchase Price (as defined in Section 3(a)
below) per share per annum (or a proportional part thereof for a portion of a
year and all subject to appropriate adjustment in the event of any stock
dividend, stock split, combination or other similar recapitalization affecting
such shares) commencing as of the date the particular shares of Series C
Preferred Stock are issued (the "Applicable Issue Date"), payable when, as and
if declared by the Board of Directors of the Company. The
<PAGE>

right to receive dividends on Series C Preferred Stock shall be non- cumulative,
and no right to receive dividends shall accrue by reason of the fact that no
dividends have been declared on the Series C Preferred Stock in any or every
prior year.

          (b) The Company shall not declare or pay any distributions on shares
of Common Stock until the holders of shares of Series C Preferred Stock then
outstanding shall have first received a distribution at the rate specified in
paragraph (a) of this Section 2 calculated on a cumulative basis from the date
of issuance of said stock compounded annually as of any anniversary of the date
of issuance of such shares.

          (c) For purposes of this Section 2, unless the context requires
otherwise, "distribution" shall mean the transfer of cash or property without
consideration, whether by way of dividend or otherwise, payable other than in
Common Stock or other securities of the Company, or the purchase or redemption
of shares of the Company (other than repurchases of Common Stock held by
employees or directors of, or consultants to, the Company pursuant to agreements
providing for such repurchase and other than redemptions in liquidation or
dissolution of the Company) for cash or property, including any such transfer,
purchase or redemption by a subsidiary of the Company.

     3.   Liquidation, Dissolution or Winding Up.
          --------------------------------------

          (a) In the event of any liquidation, dissolution or winding up of the
Company, and provided that the amount available for distribution to each holder
of the Series C Preferred Stock pursuant to this Section 3 is less than the
Applicable Purchase Price (as defined below) per share plus a dividend computed
at a rate of 7% per share per annum, compounded annually beginning as of the
Applicable Issue Date (such amount to be equitably adjusted whenever there shall
occur a stock split, combination, reclassification or other similar event as
provided in Section 5(e)(ii) hereof), whether voluntary or involuntary, the
entire assets of the Company available for such distribution shall, after
satisfaction of all payment obligations under the Company's Series A Preferred
Stock, be distributed ratably among the holders of the Series C Preferred Stock.
The "Applicable Purchase Price" for each share of Series C Preferred Stock shall
be the price paid for such share on the Applicable Issue Date.

It is expressly contemplated that separate tranches of shares of Series C
Preferred Stock issued on different dates will have different Applicable
Purchase Prices.

          (b) In the event of any liquidation, dissolution or winding up of the
Company, and provided that the amount available for distribution to each holder
of the Series C Preferred Stock pursuant to this Section 3 is at least equal to
the Applicable Purchase Price per share plus a dividend computed at a rate of 7%
of the Applicable Purchase Price for each such share per annum, compounded
annually as

                                      -2-
<PAGE>

of the Applicable Issue Date (such amount to be equitably adjusted whenever
there shall occur a stock split, combination, reclassification or other similar
event as provided in Section 5(e)(ii) hereof), whether voluntary or involuntary,
holders of each share of Series C Preferred Stock shall, after satisfaction of
all payment obligations under the Company's Series A Preferred Stock, be
entitled to be paid first out of the assets of the Company available for
distribution to holders of the Company's capital stock of all classes, whether
such assets are capital, surplus, or earnings, before any sums shall be paid or
any assets distributed among the holders of any other class of capital stock, an
amount equal to the Applicable Purchase Price for each share of Series C
Preferred Stock plus a dividend computed at a rate of 7% per share per annum,
compounded annually as of the Applicable Issue Date. After the payment of the
preferential amount required to be paid to the holders of the Series C Preferred
Stock, upon the liquidation, dissolution or winding up of the Company, the
holders of shares of the Company's Common Stock shall be entitled to receive the
remaining assets and funds of the Company available for distribution to its
stockholders.

          (c) A consolidation or merger of the Company or a sale of all or
substantially all of the assets of the Company shall be regarded as a
liquidation, dissolution or winding up of the affairs of the Company within the
meaning of this Section 3; provided, however, that each holder of Series C
Preferred Stock shall have the right to elect the benefits of the provisions of
Section 5(h) hereof in lieu of receiving payment in liquidation, dissolution or
winding up of the Company pursuant to this Section 3. Each holder of Series C
Preferred Stock shall notify the Company in advance of its election to obtain
the benefits of this Section 3(c) or of Section 5(h), which notification shall
be given not later than a date specified in writing to each holder by the
Company to be at least five (5) days prior to the effective date of such
consolidation, merger or sale. If a holder fails to make any election, he shall
be deemed to have elected the benefits of this Section 3(c).

          (d) Whenever the distribution provided for herein shall be paid in
property other than cash, the value of such distribution shall be the fair
market value of such property as determined in good faith by the Board of
Directors of the Company.

     4.   Voting Power. Except as otherwise expressly provided in Section  7
          ------------
hereof, or as required by law, each holder of Series C Preferred Stock shall be
entitled to vote on all matters and shall be entitled to that number of votes
equal to the largest number of whole shares of Common Stock into which such
holder's shares of Series C Preferred Stock could be converted, pursuant to the
provisions of Section 5 hereof (taking into account all declared and unpaid
dividends, if any, with respect to such Series C Preferred Stock), at the record
date for the determination of shareholders entitled to vote on such matter or,
if no such record date is established, at the date such vote is taken or any
written consent of shareholders is solicited.

Except as otherwise expressly provided herein or as required by law, the holders
of shares of Series C Preferred Stock and of Common Stock shall be entitled to
vote together as a class on all matters.

     5.   Conversion Rights. The holders of the Series C Preferred Stock shall
          -----------------
have the following conversion rights:

          (a) General. Subject to and in compliance with the provisions of this
              -------
Section 5, any shares of the Series C Preferred Stock, may, at the option of the
holder, be converted at any time or from time to time into fully-paid and non-
assessable shares (calculated as to each conversion to the largest whole share)
of Common Stock. The number of shares of Common Stock to which a holder of
Series C Preferred Stock shall be entitled upon conversion shall be calculated
by adding together each product obtained by multiplying the Applicable
Conversion Rate (determined as provided in Section 5(c)) for each tranche of
Series C Preferred Stock held by such holder by the number of shares of each
tranche of Series C Preferred Stock having such particular Applicable Purchase
Price being converted. Upon conversion of their shares of Series C Preferred
Stock into shares of Common Stock, holders of shares of Series C Preferred Stock
shall also have the option to have all declared but unpaid dividends on such
shares of Series C Preferred Stock converted into shares of Common Stock. The
number of shares of Common Stock to be received upon the conversion of such
declared but unpaid dividends shall, for each tranche of Series C Preferred
Stock, be computed by multiplying the number of shares of Series C Preferred
Stock which could have been purchased with such declared but unpaid dividends,
assuming a Series C Preferred Stock purchase price equal to the Applicable
Purchase Price per share, by the Applicable Conversion Rate in effect for such
tranche at the time of such conversion.

          (b) Conversion Following Underwritten Public offering.

          (i) All outstanding shares of Series C Preferred Stock shall, upon the
closing of an underwritten public offering pursuant to an effective registration
statement under the Securities Act of 1933, as amended, covering the offering
and sale of Common Stock for the account of the Company in which the Common
Stock is sold at a price to the public of not less than an amount per share to
be calculated as follows: (A) the aggregate sum of the Applicable Purchase Price
for each tranche of Series C Preferred Stock multiplied by the number of shares
issued in such tranche plus a dividend computed at a rate of 7% per share per
annum, compounded annually as of the Applicable Issue Date (such amount to be
equitably adjusted whenever there shall occur a stock split, combination,
reclassification or other similar event affecting the Common Stock) divided by
(B) the total number of shares of Series C Preferred Stock issued and
outstanding, and in which the aggregate gross proceeds (before deduction of any
underwriting discounts, commissions or expenses) received by the Company from
such public offering, shall

                                      -4-
<PAGE>

equal or exceed Fifteen Million Dollars ($15,000,000), be converted
automatically into the number of shares of Common Stock to which a holder of
Series C Preferred Stock shall be entitled upon conversion pursuant to Section
5(a) hereof without any further action by such holders and whether or not the
certificates representing such shares are surrendered to the Company or its
transfer agent for the Common Stock.

              (ii) Upon the occurrence of the conversion specified in Section
5(b)(i), the holders of such Series C Preferred Stock shall surrender the
certificates representing such shares at the office of the Company or of its
transfer agent for the Common Stock. Thereupon, there shall be issued and
delivered to each such holder a certificate or certificates for the number of
shares of Common Stock into which the shares of the Series C Preferred Stock
surrendered were convertible on the date on which such conversion occurred. The
Company shall not be obligated to issue certificates evidencing the shares of
Common Stock issuable upon such conversion unless certificates evidencing such
shares of the Series C Preferred Stock being converted are either delivered to
the Company or any such transfer agent or the holder notifies the Company or any
such transfer agent that such certificates have been lost, stolen or destroyed
and executes an agreement satisfactory to the Company to indemnify the Company
from any loss incurred by it in connection therewith. In addition, the Company
may, if the Board of Directors deems it reasonably necessary, require the holder
to post a bond in connection with such indemnity agreement.

          (c) Applicable Conversion Rate. The conversion rate in effect at any
              --------------------------
time (the "Applicable Conversion Rate") shall be the quotient obtained by
dividing (i) the Applicable Purchase Price by (ii) the Applicable Conversion
Value, calculated as provided in Section 5(d).

          (d) Applicable Conversion Value. The Applicable Conversion Value in
              ---------------------------
effect from time to time, except as subsequently adjusted in accordance with
Section 5(e) hereof, shall be equal to the quotient obtained by dividing (i) the
Applicable Purchase Price by (ii) ten (10).

          (e) Adjustments to Applicable Conversion Value.

              (i) Upon Sales of Common Stock. If the Company shall, while there
                  --------------------------
are any shares of Series C Preferred Stock outstanding, issue or sell shares of
its Common Stock without consideration or at a price per share less than the
Applicable Conversion Value for any tranche of Series C Preferred Stock in
effect immediately prior to such issuance or sale, then in each such case such
Applicable Conversion Value for such tranche of Series C Preferred Stock upon
each such issuance or sale, except as hereinafter provided, shall be adjusted to
an amount determined by multiplying such Applicable Conversion Value by a
fraction:

                                      -5-
<PAGE>

               (A) the numerator of which shall be (a) the number of shares of
               Common Stock outstanding immediately prior to the issuance of
               such additional shares of Common Stock, calculated on a fully
               diluted basis assuming exercise or conversion of all securities
               exercisable for or convertible into Common Stock, whether or not
               such exercise or conversion is unvested or otherwise conditional,
               plus (b) the number of shares of Common Stock which the net
               aggregate consideration received by the Company for the total
               number of such additional shares of Common Stock so issued would
               purchase at the Applicable Conversion Value for such tranche, and

               (B) the denominator of which shall be (a) the number of shares of
               Common Stock outstanding immediately prior to the issuance of
               such additional shares of Common Stock, calculated on a fully
               diluted basis assuming exercise or conversion of all securities
               exercisable for or convertible into Common Stock, whether or not
               such exercise or conversion is unvested or otherwise conditional,
               plus (b) the number of such additional shares of Common Stock so
               issued or deemed issued.

The Company's issuance of up to an aggregate of 3,544,737 shares of Common Stock
or such greater number if approved by a majority of the Board of Directors (such
amount to be equitably adjusted whenever there shall occur a stock split,
combination, reclassification or other similar event affecting the Common
Stock), or options exercisable therefor, pursuant to any stock purchase or stock
option plan or other individual or group incentive program of any kind approved
by the Board of Directors to the Company's officers, directors, employees or
consultants shall have no effect on the calculations contemplated by this
Section  5(e).

               (C) For the purposes of this Section 5(e), with respect to each
               tranche of Series C Preferred Stock, the issuance of any
               warrants, options, subscriptions or purchase rights with respect
               to shares of Common Stock and the issuance of any securities
               convertible into or exchangeable for shares of Common Stock (or
               the issuance of any warrants, options or any rights with respect
               to such convertible or exchangeable securities) whether or not
               such conversion or exchange is conditional, shall be deemed an
               issuance at such time of such Common Stock. Any obligation,
               agreement or undertaking to issue warrants, options,
               subscriptions or purchase rights at any time in the future

                                      -6-
<PAGE>

               shall be deemed to be an issuance at any time such obligation,
               agreement or undertaking is made or arises.  No adjustment of the
               Applicable Conversion Value for any such tranche shall be made
               under this Section 5(e) upon the issuance of any shares of
               Common Stock which are issued pursuant to the exercise of any
               warrants, options, subscriptions or purchase rights or pursuant
               to the exercise of any conversion or exchange rights in any
               convertible securities if any adjustment shall previously have
               been made upon the issuance of any such warrants, options or
               subscriptions or purchase rights or upon the issuance of any
               convertible securities (or upon the issuance of any warrants,
               options or any rights therefor) as above provided.  Any
               adjustment of the Applicable Conversion Value with respect to
               this paragraph for any tranche of Series C Preferred Stock which
               relates to warrants, options, subscriptions or purchase rights
               with respect to shares of Common Stock shall be disregarded if,
               as, and when all of such warrants, options, subscriptions or
               purchase rights expire or are canceled without being exercised,
               so that the Applicable Conversion Value for such tranche
               effective immediately upon such cancellation or expiration shall
               be equal to the Applicable Conversion Value for such tranche in
               effect at the time of the issuance of the expired or canceled
               warrants, options, subscriptions or purchase rights, with such
               additional adjustments as would have been made to that Applicable
               Conversion Value had the expired or canceled warrants, options,
               subscriptions or purchase rights not been issued.

     For purposes of this Section 5(e), if a part or all of the consideration
received by the Company in connection with the issuance of shares of the Common
Stock or the issuance of any of the securities described in this Section  5(e)
consists of property other than cash, the Company at its expense will promptly
cause independent public accountants of recognized standing selected by the
Company to value such property, whereupon such value shall be given to such
consideration and shall be recorded on the books of the Company with respect to
receipt of such property.

     This Section 5(e)(i) shall not apply under any of the circumstances which
would constitute an Extraordinary Common Stock Event (as hereinafter defined in
Section  5(e)(ii)).

                                      -7-
<PAGE>

             (ii) Extraordinary Common Stock Event.  Upon the happening of an
                  --------------------------------
Extraordinary Common Stock Event (as hereinafter defined), the Applicable
Conversion Value for each tranche of Series C Preferred Stock shall,
simultaneously with the happening of such Extraordinary Common Stock Event, be
adjusted by multiplying the then effective Applicable Conversion Value for such
tranche by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to such Extraordinary Common Stock
Event and the denominator of which shall be the number of shares of Common Stock
outstanding immediately after such Extraordinary Common Stock event, and the
product so obtained shall thereafter be the Applicable Conversion Value for such
tranche.  The Applicable Conversion Value for such tranche, as so adjusted,
shall be readjusted in the same manner upon the happening of any successive
Extraordinary Common Stock Event or Events.

     "Extraordinary Common Stock Event" shall mean (i) the issue of additional
shares of Common Stock as a dividend or other distribution on outstanding shares
of Common Stock, (ii) the subdivision of outstanding shares of Common Stock into
a greater number of shares of Common Stock, or (iii) the combination of
outstanding shares of the Common Stock into a smaller number of shares of Common
Stock.

          (f) Dividends.  In the event the Company shall make or issue, or fix a
              ---------
record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in securities of the Company
other than shares of Common Stock or in assets (excluding cash dividends or
distributions), then and in each such event provisions shall be made so that the
holders of Series C Preferred Stock shall receive upon conversion thereof in
addition to the number of shares of Common Stock receivable thereupon, the
number of securities or such other assets of the Company which they would have
received had their Series C Preferred Stock been converted into Common Stock on
the date of such event and had they thereafter, during the period from the date
of such event to and including the Conversion Date (as that term is hereafter
defined in Section  5(j)), retained such securities or such other assets
receivable by them as aforesaid during such period, giving application to all
adjustments called for during such period under this Section  5 with respect to
the rights of the holders of the Series C Preferred Stock.

          (g) Recapitalization or Reclassification.  If the Common Stock
              ------------------------------------
issuable upon the conversion of the Series C Preferred Stock shall be changed
into the same or a different number of shares of any class or classes of stock
of the Company, whether by recapitalization, reclassification or otherwise
(other than a subdivision or combination of shares or stock dividend provided
for elsewhere in this Section  5, or a reorganization, merger, consolidation or
sale of assets provided for elsewhere in this Section  5), then and in each such
event the holder of each share of Series C Preferred Stock shall have the right
thereafter to convert such share into the kind and amount of shares of stock and
other securities and property receivable upon such

                                      -8-
<PAGE>

reorganization, reclassification or other change by holders of the number of
shares of Common Stock into which such share of Series C Preferred Stock might
have been converted (taking into account all accrued and unpaid dividends and
interest with respect to such Series C Preferred Stock) immediately prior to
such reorganization, reclassification or change, all subject to further
adjustment as provided herein.

          (h)  Capital Reorganization Merger or Sale of Assets.  If at any time
               -----------------------------------------------
or from time to time there shall be a capital reorganization of the Common Stock
(other than a subdivision, combination, reclassification or exchange of shares
provided for elsewhere in this Section  5) or a merger or consolidation of the
Company with or into another corporation or entity, or the sale of all or
substantially all of the Company's properties and assets to any other person or
persons, then, as a part of such reorganization, merger, consolidation or sale,
provision shall be made so that each holder of the Series C Preferred Stock
shall thereafter be entitled to receive upon conversion of such holder's shares
of Series C Preferred Stock, the number of shares of stock or other securities
or property of the Company, or of the successor corporation or entity resulting
from such merger, consolidation or sale, to which a holder of Common Stock
issuable upon conversion would have been entitled on such capital
reorganization, merger, consolidation, or sale.  In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section  5
with respect to the rights of the holders of the Series C Preferred Stock after
the reorganization, merger, consolidation or sale to the end that the provisions
of this Section  5 (including adjustment of the Applicable Conversion Value then
in effect and the number of shares purchasable upon conversion of each tranche
of Series C Preferred Stock) shall be applicable after that event in as nearly
equivalent a manner as may be practicable.

     Each holder of Series C Preferred Stock upon the occurrence of a capital
reorganization, merger or consolidation of the Company, or the sale of all or
substantially all its assets and properties as such events are more fully set
forth in the first paragraph of this Section  5(h), shall have the option of
electing treatment of his shares of Series C Preferred Stock under either this
Section  5(h) or Section  3(b) hereof, notice of which election shall be
submitted in writing to the Company at its principal offices no later than five
(5) days before the effective date of such event.

          (i)  Accountant's Certificate as to Adjustments.  In each case of an
               ------------------------------------------
adjustment or readjustment of the Applicable Conversion Rate, the Company will
furnish each holder of Series C Preferred Stock with a certificate, prepared by
its chief financial officer showing such adjustment or readjustment, and stating
in detail the facts upon which such adjustment or readjustment is based.  Upon
the request of any holder, the Company will cause its independent public
accountants to confirm the accuracy of such adjustment or readjustment.

                                      -9-
<PAGE>

          (j) Exercise of Conversion Privilege.  To exercise his conversion
              --------------------------------
privilege, a holder of Series C Preferred Stock shall surrender the certificate
or certificates representing the shares being converted to the Company at its
principal office, and shall give written notice to the Company at such office
that such holder elects to convert such shares.  Such notice shall also state
the name or names (with address or addresses) in which the certificate or
certificates for shares of Common Stock issuable upon such conversion shall be
issued.  The certificate or certificates for shares of Series C Preferred Stock
surrendered for conversion shall be accompanied by proper assignment thereof to
the Company or in blank.  The date when such written notice is received by the
Company, together with the certificate or certificates representing the shares
of Series C Preferred Stock being converted, shall be the "Conversion Date".  As
promptly as practicable after the Conversion Date, the Company shall issue and
shall deliver to the holder of the shares of Series C Preferred Stock being
converted, or on its written order, such certificate or certificates as it may
request for the number of whole shares of Common Stock issuable upon the
conversion of such shares of Series C Preferred Stock in accordance with the
provisions of this Section  5, cash in the amount of all declared but unpaid
dividends on such shares of Series C Preferred Stock, up to and including the
Conversion Date, unless conversion of such declared but unpaid dividends into
Common Stock has been elected, and cash, as provided in Section  5(k), in
respect of any fraction of a share of Common Stock issuable upon such
conversion. Such conversion shall be deemed to have been effected immediately
prior to the close of business on the Conversion Date, and at such time the
rights of the holder as holder of the converted shares of Series C Preferred
Stock shall cease and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock shall be issuable upon
such conversion shall be deemed to have become the holder or holders of record
of the shares of Common Stock represented thereby.

          (k) Cash in Lieu of Fractional Shares.  No fractional shares of Common
              ---------------------------------
Stock or scrip representing fractional shares shall be issued upon the
conversion of shares of Series C Preferred Stock.  Instead of any fractional
shares of Common Stock which would otherwise be issuable upon conversion of
Series C Preferred Stock, the Company shall pay to the holder of the shares of
Series C Preferred Stock which were converted a cash adjustment in respect of
such fractional shares in an amount equal to the same fraction of the market
price per share of the Common Stock (as determined in a reasonable manner
prescribed by the Board of Directors) at the close of business on the Conversion
Date.  The determination as to whether or not any fractional shares are issuable
shall be based upon the total number of shares of Series C Preferred Stock being
converted at any one time by any holder thereof, not upon each share of Series C
Preferred Stock being converted.

          (l) Partial Conversion.  In the event some but not all of the shares
              ------------------
of Series C Preferred Stock represented by a certificate or certificates
surrendered by a holder are converted, the Company shall execute and deliver to
or on the order of the

                                     -10-
<PAGE>

 holder, at the expense of the Company, a new certificate representing the
number of shares of Series C Preferred Stock which were not converted.

          (m) Reservation of Common Stock.  The Company shall at all times
              ---------------------------
reserve and keep available out of its authorized but unissued shares of Common
Stock, solely for the purpose of effecting the conversion of the shares of the
Series C Preferred Stock, such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all outstanding
shares of the Series C Preferred Stock and all unpaid dividends thereon, and if
at any time the number of authorized but unissued shares of Common Stock shall
not be sufficient to effect the conversion of all then outstanding shares of the
Series C Preferred Stock and all unpaid dividends thereon, the Company shall
take such corporate action as may be necessary to increase its authorized but
unissued shares of Common Stock to such number of shares as shall be sufficient
for such purpose.

     6.   No Reissuance of Series C Preferred Stock.  No share or shares of
          -----------------------------------------
Series C Preferred Stock acquired by the Company by reason of redemption,
purchase, conversion or otherwise shall be reissued, and all such shares shall
be canceled, retired and eliminated from the shares which the Company shall be
authorized to issue.  The Company may from time to time take such appropriate
corporate action as may be necessary to reduce the authorized number of shares
of the Series C Preferred Stock accordingly.

     7.   Restrictions and Limitations.
          ----------------------------

          (a) Except as expressly provided herein or as required by law, neither
the Company nor any subsidiary of the Company (which shall mean any corporation
or trust of which the Company directly or indirectly owns at the time all of the
outstanding shares of every class of such corporation or trust other than
directors' qualifying shares) shall, without the vote or written consent by the
holders of at least a majority of the then outstanding shares of the Series C
Preferred Stock voting together, each share of Series C Preferred Stock to be
entitled to one vote in each instance for each share of Common Stock into which
such Preferred Stock is then convertible:

             (i)   Redeem, purchase or otherwise acquire for value or (pay in,
to or set aside for a sinking fund for such purpose), any share or shares of
Series C Preferred Stock;

             (ii)  Authorize or issue, or obligate itself to authorize or issue,
any other equity security senior to or on a parity with the Series C Preferred
Stock as to liquidation preferences, conversion rights, redemption rights,
dividend rights, voting rights or otherwise;

                                     -11-
<PAGE>

             (iii) Effect any sale, lease, assignment, transfer or other
conveyance of all or substantially all of the assets of the Company or any
subsidiary thereof, or any consolidation or merger involving the Company or any
subsidiary thereof, or any reclassification or other change of stock, or any
recapitalization or any dissolution, liquidation or winding up of the Company;

             (iv)  Effect any merger by the Company with or into any business
entity or any acquisition by the Company of any assets or business having a fair
market value in excess of One Million Dollars ($1,000,000) U.S.; or

             (v)   Amend its Amended and Restated Certificate of Incorporation,
if such amendment would change any of the rights, preferences, privileges of or
limitations provided for herein for the benefit of any shares of Series C
Preferred Stock.

     8.   No Dilution or Impairment.  Except as provided in Section  7 above,
          -------------------------
the Company will not, by amendment of its Amended and Restated Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of the
Series C Preferred Stock set forth herein, but will at all times in good faith
assist in the carrying out of all such terms and in the taking of all such
actions as may be necessary or appropriate in order to protect the rights of the
holders of the Series C Preferred Stock against dilution or other impairment.
Without limiting the generality of the foregoing, the Company (a) will not
increase the par value of any shares of stock receivable on the conversion of
the Series C Preferred Stock above the amount payable therefor on such
conversion, (b) will take all such action as may be necessary or appropriate in
order that the Company may validly and legally issue fully paid and non-
assessable shares of stock on the conversion of all Series C Preferred Stock
from time to time outstanding and all accrued and unpaid dividends thereon, and
(c) will not transfer all or substantially all of its properties and assets to
any other person (corporate or otherwise), or consolidate with or merge into any
other person or permit any such person to consolidate with or merge into the
Company (if the Company is not the surviving person), unless such other person
shall expressly assume in writing and will be bound by all the terms of the
Series C Preferred Stock set forth herein.

     9.   Notices of Record Date.  In the event of
          ----------------------

          (a) any taking by the Company of a record of the holders of any class
of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

                                     -12-
<PAGE>

          (b) any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company, any merger or
consolidation of the Company, or any transfer of all or substantially all of the
assets of the Company to any other corporation, or any other entity or person,
or

          (c) any voluntary or involuntary dissolution, liquidation or winding
up of the Company, then and in each such event the Company shall mail or cause
to be mailed to each holder of Series C Preferred Stock a notice specifying (i)
the date on which any such record is to be taken for the purpose of such
dividend, distribution or right and a description of such dividend, distribution
or right, (ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding up is expected to become effective, (iii) the time, if any, that is to
be fixed, as to when the holders of record of Common Stock (or other securities)
shall be entitled to exchange their shares of Common Stock (or other securities)
for securities or other property deliverable upon such reorganization,
reclassification, recapitalization, transfer, consolidation, merger,
dissolution, liquidation or winding up.  Such notice shall be mailed at least
twenty (20) days prior to the date specified in such notice on which such action
is to be taken.

     This Certificate of Designation was duly adopted in accordance with the
applicable provisions of Section 151 of the Delaware General Corporation Law.

$20,000,000                                            as of FEBRUARY 1, 1999
                                                         Andover, Massachusetts

     FOR VALUE RECEIVED, the undersigned ENGAGE TECHNOLOGIES, INC., a Delaware
corporation (the "Borrower"), hereby promises to pay to the order of CMGI, INC.,
                  --------
a Delaware corporation (the "Lender"), ON DEMAND the lesser of (i) the principal
                             ------
sum of Twenty Million Dollars ($20,000,000) or (ii) the aggregate unpaid
principal amount of all advances hereunder, together with accrued interest
thereon. Interest, if not paid, shall be added to principal monthly (and
interest shall thereafter accrue thereon) on the last day of each calendar month
at the rate of seven percent (7%) per annum based on the average of (i) the
aggregate unpaid principal amount of all advances made hereunder as of the last
day of the immediately preceding month and (ii) the aggregate unpaid principal
amount of all advances made hereunder as of the last day of the month for which
interest is being calculated.  The unpaid principal balance and all accrued
interest on this Note at any time shall be determined from the records of the
Lender which shall constitute presumptive evidence of such amounts and may be
summarized on Schedule I hereto, which may be updated by the Lender from time to
              ----------
time to reflect new advances and repayment or conversion of indebtedness.  As
soon as practicable after each January 31, April 30, July 31 and October 31
(each a "Fiscal Quarter End"), the Borrower shall provide notice to the Lender
         ------------------
of the Conversion Price applicable to the fiscal quarter then ended.
NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS NOTE SHALL OBLIGATE THE LENDER TO
MAKE ANY ADVANCES HEREUNDER.

     Advances in the aggregate amount of $9,347,451 (representing $5,334,605
advanced on or before April 30, 1998, an additional $2,418,456 advanced on or
before July 31, 1998, an additional $598,117 advanced on or before October 31,
1998 and an additional $996,273 advanced on or before January 31, 1999, in each
case including interest accrued during the applicable fiscal quarter) made by
the Lender to the Borrower prior to the date hereof shall be converted into
164,371 shares of Series C Stock (as defined below) of the Borrower (based upon
applicable conversion prices of $4.75, $6.95, $8.50 and $9.74, respectively) as
soon as practicable after the date hereof without further accrual of interest
thereon and shall not constitute advances hereunder.

     The Lender, in its sole discretion, will at any time and from time to time
have the option, exercisable by written notice to the Borrower in substantially
the form attached as Exhibit A hereto, to require the Borrower to satisfy all or
                     ---------
any part of the indebtedness represented by this Note (including both principal
and accrued interest) by issuing to the Lender (or its nominee(s)) shares of the
Borrower's capital stock in the following manner:

          (A) prior to a Qualified Public Offering, the Borrower shall issue
     that number of shares of its Series C Convertible Preferred Stock, $0.01
     par value per share (the "Series C Stock"), equal to one-tenth of the
                               --------------
     quotient of (i) the aggregate
<PAGE>

     amount of principal and interest to be so converted for any particular date
     divided by (ii) the applicable Conversion Price (as defined below,
     -------
     proportionately adjusted in the event that from time to time following the
     date of determination thereof there occurs any stock dividend, stock split,
     reverse stock split, recapitalization, or other similar event affecting the
     Borrower's Series C Stock); and

          (B) following a Qualified Public Offering, the Borrower shall issue
     that number of shares of its common stock, $0.01 par value per share (the
     "Common Stock"), equal to the quotient of (i) the aggregate amount of
     -------------
     principal and interest to be so converted for any particular date divided
                                                                       -------
     by (ii) the applicable Conversion Price (as defined below, proportionately
     adjusted in the event that from time to time following the date of
     determination thereof there occurs any stock dividend, stock split, reverse
     stock split, recapitalization, or other similar event affecting the
     Borrower's Common Stock).

A "Qualified Public Offering" shall mean a transaction which triggers the
   -------------------------
mandatory conversion into Common Stock of the Series C Stock pursuant to the
terms of Section 5(b) of the Certificate of Designation of the Series C Stock.

     The "Conversion Price" applicable to the conversion of the principal amount
          ----------------
of advances made, and interest accrued, during any particular fiscal quarter
shall be determined as of the Fiscal Quarter End for that particular fiscal
quarter by dividing (i) the total enterprise valuation of the Borrower (as
determined by the Board of Directors of the Borrower in good faith and in a
manner satisfactory to the Lender in all respects) as of the Fiscal Quarter End
for that particular fiscal quarter by (ii) the number of shares of the
Borrower's Common Stock outstanding at such Fiscal Quarter End determined on a
fully-diluted, as-if-converted basis (and assuming the conversion of all
convertible securities, the grant of all options available under any option
plans and the exercise of all options, whether vested and unvested, warrants and
other rights to acquire equity interests in the Borrower of any nature
whatsoever). It is expressly contemplated that advances made, and interest
accrued, during each fiscal quarter will have a different applicable Conversion
Price depending upon the total enterprise valuation and number of shares of
Common Stock deemed outstanding as of the Fiscal Quarter End for that particular
fiscal quarter. Notwithstanding the foregoing, (i) the Conversion Price
applicable to the principal amount of advances made, and interest accrued,
during the fiscal quarter in which a Qualified Public Offering occurs shall be
equal to the price per share of Common Stock to the public in such offering and
(ii) the Conversion Price applicable to the principal amount of any advances
made, and interest accrued, during a fiscal quarter if the Lender elects to
convert such advances and/or interest prior to the Fiscal Quarter End of such
fiscal quarter shall be the Conversion Price in effect for the immediately
preceding fiscal quarter.

                                      -2-

     This Note may be voluntarily prepaid in whole or in part at any time
without premium or penalty upon thirty (30) days written notice to the Lender.
Any such prepayment shall be applied to advances and compounded interest in
inverse order of incurrence.

     If any payment of principal or interest hereon shall become due on a day
which is not a day on which banks are open for normal business hours in Andover
or Boston, Massachusetts, such payment shall be made on the next succeeding
business day and such extension of time shall in such case be included in
computing interest in connection with such payment.

     Payments of both principal and interest hereon shall be made in immediately
available funds at the office of the Lender, at Andover, Massachusetts, or at
such other place as the holder hereof shall designate to the Borrower in
writing, in lawful money of the United States of America.

     This Note will be secured by certain assets of the Borrower pursuant to a
certain Security Agreement and a certain Intellectual Property Security
Agreement (the "Security Agreements"), to be entered into between the Borrower
                -------------------
and the Lender.  The rights of the Lender under this paragraph are in addition
to any other rights and remedies (including other rights of setoff) which the
Lender may have.  The Lender shall be permitted to exercise its rights as a
secured party under the Security Agreements to the extent permitted by
applicable law.

     Except to the extent otherwise required by the context of this Note, the
word "Lender" wherever used herein shall mean and include the holder of this
Note originally issued to CMGI, Inc.

     This Note for all purposes shall be governed by and construed in accordance
with the laws of the Commonwealth of Massachusetts without regard to its
conflicts of laws rules. The Borrower waives presentment, demand, notice,
protest and all other demands and notices in connection with the delivery,
acceptance, performance, default and enforcement of this Note. The Borrower
hereby irrevocably and unconditionally submits, for itself and its property, to
the non-exclusive jurisdiction of the courts of the Commonwealth of
Massachusetts and of the United States District Court for the District of
Massachusetts, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Note or the Security Agreements,
or for recognition or enforcement of any judgment, and the Borrower hereby
irrevocably and unconditionally agrees that all claims in respect of any such
action or proceeding may be heard and determined in such Massachusetts court
(or, to the extent permitted by law, in such Federal court). The Borrower agrees
that a final judgment in any such action or proceeding shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or in any other
manner provided by law. Nothing in this Note shall affect any

                                      -3-

right that the Lender may otherwise have to bring any action or proceeding
relating to this Note against the Borrower or its properties in the courts of
any jurisdiction.

     THE LENDER AND THE BORROWER AGREE THAT NEITHER OF THEM NOR ANY ASSIGNEE OR
SUCCESSOR SHALL (A) SEEK A JURY TRIAL IN ANY LAWSUIT, PROCEEDING, COUNTERCLAIM
OR ANY OTHER ACTION BASED UPON, OR ARISING OUT OF, THIS NOTE, ANY RELATED
INSTRUMENTS, ANY COLLATERAL OR THE DEALINGS OR THE RELATIONSHIP BETWEEN OR AMONG
ANY OF THEM, OR (B) SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN
WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. THE PROVISIONS OF THIS
PARAGRAPH HAVE BEEN FULLY DISCUSSED BY THE LENDER AND THE BORROWER, AND THESE
PROVISIONS SHALL BE SUBJECT TO NO EXCEPTIONS. NEITHER THE LENDER NOR THE
BORROWER HAS AGREED WITH OR REPRESENTED TO THE OTHER THAT THE PROVISIONS OF THIS
PARAGRAPH WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.

     If any provision of this Note shall be held invalid or unenforceable by any
court of competent jurisdiction, that holding shall not invalidate or render
unenforceable any other provision hereof.

                                                              ------

     WHEREAS, the Lender has agreed, in its sole discretion, to advance funds to

Secured Convertible Demand Note dated as of February 1, 1999 (the "Note"); and
                                                                   ----

     WHEREAS, the willingness of the Lender to make the Loans is subject to the
condition, among others, that the Debtor shall execute and deliver this
Agreement and grant the security interest hereinafter described;

     NOW THEREFORE, in consideration of the willingness of the Lender to make

interest in and lien on all of the tangible and intangible personal property and
fixtures of the Debtor, including without limitation the property described
below, whether now owned or existing or hereafter acquired or arising, together
with any and all additions thereto and replacements therefor and proceeds and

                                                               ----------

limitation all present and future goods, inventory (including, without
limitation, all printed materials, merchandise, raw materials, work in process,
finished goods and supplies), equipment, merchandise, furniture, fixtures,
office supplies, motor vehicles, machinery, paper, tools, computers, and
associated equipment now owned or hereafter acquired, including, without
limitation, the tangible personal property used in the operation of the
businesses of the Debtor;

          (b) to the extent that such rights are assignable as collateral, the
Debtor's rights under all present and future authorizations, permits, licenses
and franchises issued, granted or licensed to the Debtor for the operation of
its business,
<PAGE>

including, without limitation, each of the authorizations, permits, licenses and
franchises listed on the Intellectual Property Security Agreement executed this
date from the Debtor to the Lender;

          (c) to the extent that such rights are assignable, all of the Debtor's
rights under all present and future vendor or customer contracts and all
franchise, distribution, construction, engineering, management, direct marketing
and advertising and related agreements; and

          (d) all of the Debtor's other personal property, including, without
limitation, all present and future accounts, accounts receivable, investment
property, rights to proceeds of letters of credit, contract rights, general
intangibles (including without limitation, all goodwill, all trademarks,
intellectual property, all customer lists, vendor lists, and other printed
materials, including all catalogs, indexes, lists, data and other documents and
papers relating thereto, blue prints, designs and research and development), any
information stored on any medium, including electronic medium, related to any of
the personal property of the Debtor, all instruments, documents and chattel
paper, and all debts, obligations and liabilities in whatever form owing to the
Debtor from any person, firm or corporation or any other legal entity, whether
now existing or hereafter arising, now or hereafter received by or belonging or
owing to the Debtor, and all guaranties and security therefor.

     Any of the foregoing terms which are defined in the Uniform Commercial Code
shall have the meaning provided in the Uniform Commercial Code as supplemented
and expanded by the foregoing.

     3.   Secured Obligations.  The security interest hereby granted shall
          -------------------
secure the due and punctual payment and performance of the following liabilities
and obligations of the Debtor (herein called the "Secured Obligations"):
                                                  -------------------

          (a) Principal of and premium, if any, and interest on the Loans;

          (b) Any and all obligations of the Debtor to the Lender under the
Note; and

          (c) Any and all other obligations of the Debtor to the Lender.

     4.   Perfection Certificate.  The Debtor has delivered to the Lender a
          ----------------------
Perfection Certificate in the form appended hereto as Schedule I.  The Debtor
represents to the Lender that the completed Perfection Certificate delivered to
the Lender is true and correct in every respect and the facts contained in such
certificate are accurate.  The Debtor shall supplement the Perfection
Certificate promptly after

                                       2
<PAGE>

obtaining information which would require a correction or addition to the
Perfection Certificate.

     5.   Special Warranties and Covenants of the Debtor.  The Debtor hereby
          ----------------------------------------------
warrants and covenants to the Lender that:

          (a) The address shown at the beginning of this Agreement is the
current principal place of business of the Debtor, and all of the Debtor's
current additional places of business, if any, and the locations of all of the
Collateral currently are listed in the Perfection Certificate delivered pursuant
to Section 4 above. The Debtor will not change its principal or any other place
of business, or the location of any Collateral from the locations set forth in
the Perfection Certificate, or make any change in the Debtor's name or conduct
the Debtor's business operations under any fictitious business name or trade
name, without, in any such case, at least thirty (30) days' prior written notice
to the Lender.

          (b) Except for the security interest created hereunder, the Debtor is
the owner of the Collateral free from any lien, security interest or encumbrance
and the Debtor will defend the Collateral against all claims and demands of all
persons at any time claiming the same or any interest therein.

          (c) Except as otherwise consented to in writing by the Lender, the
Debtor will not sell or otherwise dispose of any of the Collateral or any
interest therein nor will the Debtor create, incur or permit to exist any
mortgage, lien, charge, encumbrance or security interest whatsoever with respect
to the Collateral.

          (d) Except for Collateral that is obsolete or no longer used in the
Debtor's business, the Debtor will keep the Collateral in good order and repair
(normal wear excepted) and adequately insured at all times.  The Debtor will pay
promptly when due all taxes and assessments on the Collateral or for its use or
operation, except for taxes and assessments contested in good faith and for
which adequate reserves are created.  The Lender may at its option discharge any
taxes, liens, security interests or other encumbrances to which any Collateral
is at any time subject, and may, upon the failure of the Debtor to do so in
accordance with the terms hereof, purchase insurance on any Collateral and pay
for the repair, maintenance or preservation thereof, and the Debtor agrees to
reimburse the Lender on demand for any payments or expenses incurred by the
Lender pursuant to the foregoing authorization and any unreimbursed amounts
shall constitute Secured Obligations for all purposes hereof.

          (e) The Collateral may be transferred to a third party upon a default
without the consent of any other third party.

                                       3
<PAGE>

          (f) The Debtor will promptly execute and deliver to the Lender such
financing statements, certificates and other documents or instruments as may be
necessary to enable the Lender to perfect or from time to time renew the
security interest granted hereby, including, without limitation, such financing
statements, certificates and other documents as may be necessary to perfect a
security interest in any additional Collateral hereafter acquired by the Debtor
or in any replacements or proceeds thereof.  The Debtor authorizes and appoints
the Lender, in case of need, to execute such financing statements, certificates
and other documents pertaining to the Lender's security interest in the
Collateral in its stead, with full power of substitution, as the Debtor's
attorney in fact.  The Lender may from time to time request and the Debtor shall
deliver copies of all customer lists and vendor lists.  The Debtor further
agrees that a carbon, photographic or other reproduction of a security agreement
or financing statement is sufficient as a financing statement under this
Agreement.

          (g) The Debtor will give the Lender notice of each office at which
records of the Debtor pertaining to all intangible items of Collateral are kept.
Except as may be provided in such notice, the records concerning all intangible
Collateral are and will be kept at the address shown at the beginning of this
Agreement as the principal place of business of the Debtor.

          (h) To the extent that the Debtor is a beneficiary under any written
Letter of credit now or hereafter issued in favor of the Debtor, the Debtor
shall deliver such Letter of credit to the Lender.  The Lender shall from time
to time, at the request and expense of the Debtor, make such arrangements with
the Debtor as are in the Lender's reasonable judgment necessary and appropriate
so that the Debtor may make any drawing to which the Debtor is entitled under
such Letter of credit, without impairment of the Lender's perfected security
interest in the Debtor's rights to the proceeds of such Letter of credit or in
the actual proceeds of such drawing.  At the Lender's request, the Debtor shall,
for any Letter of credit, whether or not written, now or hereinafter issued in
favor of the Debtor as beneficiary, execute and deliver to the issuer any
confirmer of such Letter of credit an assignment of proceeds form, in favor of
the Lender and satisfactory to the Lender and such issuer or (as the case may
be) such confirmer, requiring the proceeds of any drawing under such Letter of
credit to be paid directly to the Lender for application under the Note.

     6.   Fixtures, etc.  It is the intention of the parties hereto that none of
          -------------
the Collateral shall become fixtures and the Debtor will take all such
reasonable action or actions as may be necessary to prevent any of the
Collateral from becoming fixtures. Without limiting the generality of the
foregoing, the Debtor will, if requested by the Lender, use commercially
reasonable efforts to obtain waivers of lien, in form satisfactory to the
Lender, from each lessor of real property on which any of the Collateral is or
is to be located.

     7.   Events of Default.  The Debtor shall be in default under this
          -----------------
Agreement (an "Event of Default") upon the happening of any Event of Default
               ----------------
under the Note.

     8.   Rights and Remedies of Lender.  Upon the occurrence of any Event of
          -----------------------------
Default, such default not having previously been waived, remedied or cured, the
Lender shall have the following rights and remedies:

          (a) All rights and remedies provided by law, including, without
limitation, those provided by the Uniform Commercial Code;

          (b) All rights and remedies provided in this Agreement; and

          (c) All rights and remedies provided in any other agreement, document
or instrument pertaining to the Secured Obligations.

     9.   Right of Lender to Dispose of Collateral, etc.  Upon the occurrence of
          ---------------------------------------------
any Event of Default, such Event of Default not having previously been waived,
remedied or cured, but subject to the provisions of the Uniform Commercial Code
or other applicable law, the Lender shall have the right to take possession of
the Collateral and, in addition thereto, the right to enter upon any premises on
which the Collateral or any part thereof may be situated and remove the same
therefrom.  The Lender may require the Debtor to make the Collateral (to the
extent the same is moveable) available to the Lender at a place to be designated
by the Lender which is reasonably convenient to both parties or transfer any
information related to the Collateral to the Lender by electronic medium.
Unless the Collateral is perishable or threatens to decline speedily in value or
is of a type customarily sold on a recognized market, the Lender will give the
Debtor at least ten (10) days' prior written notice in accordance with paragraph
18 hereof of the time and place of any public sale of any of the Collateral or
of the time after which any private sale or any other intended disposition
thereof is to be made.  Any such notice shall be deemed to meet any requirement
hereunder or under any applicable law (including the Uniform Commercial Code)
that reasonable notification be given of the time and place of such sale or
other disposition.

     10.  Note.  Notwithstanding any other provision of this Agreement, the
          ----
rights of the parties hereunder are subject to the provisions of the Note.

     11.  Right of Lender to Use and Operate Collateral, etc.  Upon the
          --------------------------------------------------
occurrence of any Event of Default, such default not having previously been
waived, remedied or cured, but subject to the provisions of the Uniform
Commercial Code or other applicable law, the Lender shall have the right and
power to take possession of all or any part of the Collateral, and to exclude
the Debtor and all persons claiming under the Debtor wholly or partly therefrom,
and thereafter to hold, store, and/or use, operate, manage and control the same.
Upon any such taking of possession, the

                                       5
<PAGE>

Lender may, from time to time, at the expense of the Debtor, make all such
repairs, replacements, alterations, additions and improvements to and of the
Collateral as the Lender may deem proper. In any such case the Lender shall have
the right to manage and control the Collateral and to carry on the business and
to exercise all rights and powers of the Debtor in respect thereto as the Lender
shall deem best, including the right to enter into any and all such agreements
with respect to the operation of the Collateral or any part thereof as the
Lender may see fit; and the Lender shall be entitled to collect and receive all
rents, issues, profits, fees, revenues and other income of the same and every
part thereof. Such rents, issues, profits, fees, revenues and other income shall
be applied to pay the expenses of holding and operating the Collateral and of
conducting the business thereof, and of all maintenance, repairs, replacements,
alterations, additions and improvements, and to make all payments which the
Lender may be required or may elect to make, if any, for taxes, assessments,
insurance and other charges upon the Collateral or any part thereof, and all
other payments which the Lender may be required or authorized to make under any
provision of this Agreement (including legal costs and attorneys' fees). The
remainder of such rents, issues, profits, fees, revenues and other income shall
be applied as provided in paragraph 13. Without limiting the generality of the
foregoing or limiting in any way the rights of the Lender under applicable law,
at any time after (i) the entire principal balance of any Loan shall have become
due and payable (whether at maturity, by acceleration or otherwise) and (ii) the
Lender shall have provided to the Debtor not less than ten (10) days prior
written notice of its intention to apply for a receiver, the Lender shall be
entitled to apply for and have a receiver appointed under state or federal law
by a court of competent jurisdiction in any action taken by the Lender to
enforce its rights and remedies hereunder in order to manage, protect, preserve,
sell and otherwise dispose of all or any portion of the Collateral and continue
the operation of the business of the Debtor, and to collect all revenues and
profits thereof and apply the same to the payment of all expenses and other
charges of such receivership, including the compensation of the receiver, and to
the payment of the Secured Obligations as aforesaid until a sale or other
disposition of such Collateral shall be finally made and consummated. THE DEBTOR
HEREBY IRREVOCABLY CONSENTS TO AND WAIVES ANY RIGHT TO OBJECT TO OR OTHERWISE
CONTEST THE APPOINTMENT OF RECEIVER AS PROVIDED ABOVE. THE DEBTOR (I) GRANTS
SUCH WAIVER AND CONSENT KNOWINGLY AFTER HAVING DISCUSSED THE IMPLICATIONS
THEREOF WITH COUNSEL, (II) ACKNOWLEDGES THAT (A) THE UNCONTESTED RIGHT TO HAVE A
RECEIVER APPOINTED FOR THE FOREGOING PURPOSES IS CONSIDERED ESSENTIAL BY THE
LENDER IN CONNECTION WITH THE ENFORCEMENT OF IT S RIGHTS AND REMEDIES HEREUNDER
AND UNDER THE NOTE, AND (B) THE AVAILABILITY OF SUCH APPOINTMENT AS A REMEDY
UNDER THE FOREGOING CIRCUMSTANCES WAS A MATERIAL FACTOR IN INDUCING THE LENDER
TO MAKE THE LOANS TO THE DEBTOR, AND (III) AGREES TO ENTER INTO ANY AND ALL
STIPULATIONS IN ANY LEGAL ACTIONS, OR AGREEMENTS OR OTHER INSTRUMENTS IN

                                       6
<PAGE>

CONNECTION WITH THE FOREGOING AND TO COOPERATE FULLY WITH THE LENDER IN
CONNECTION WITH THE ASSUMPTION AND EXERCISE OF CONTROL BY THE RECEIVER OVER ALL
OR ANY PORTION OF THE COLLATERAL. THE LENDER ACKNOWLEDGES AND AGREES THAT
NOTHING IN THIS PARAGRAPH 11 SHALL BE DEEMED TO CONSTITUTE A WAIVER OF THE
DEBTOR'S RIGHT TO FILE FOR PROTECTION UNDER TITLE 11 OF THE UNITED STATES CODE
AT ANY TIME PRIOR TO THE APPOINTMENT OF A RECEIVER.

     12.  Collection of Accounts Receivable, etc.  Upon the occurrence of any
          --------------------------------------
Event of Default, such default not having previously been waived, remedied or
cured, the Lender may notify or may require the Debtor to notify account
debtors, including without limitation, customers and vendors, obligated on any
or all of the Debtor's accounts receivable, whether now existing or hereafter
arising, to make payment directly to the Lender, and may take possession of all
proceeds of any accounts in the Debtor's possession, and may take any other
steps which the Lender deems necessary or advisable to collect any or all such
accounts receivable or other Collateral or proceeds thereof.

     13.  Proceeds of Collateral.  After deducting all costs and expenses of
          ----------------------
collection, storage, custody, sale or other disposition and delivery (including
legal costs and attorneys' fees) and all other charges against the Collateral,
the residue of the proceeds of any such sale or disposition shall be applied to
the payment of the Secured Obligations in such order of priority as the Lender
shall determine (consistent with the Credit Agreement) and any surplus shall be
returned to the Debtor or to any person or party lawfully entitled thereto
(including, if applicable, any subordinated creditors of the Debtor).  By way of
enlargement and not by way of limitation of the rights of the Lender under
applicable law or the Note, the Lender shall be entitled to allocate its
application of the Collateral, and the proceeds thereof, to the Secured
Obligations (including without limitation the Loans) in such proportions and in
such order as the Lender, in its sole discretion, shall decide (consistent with
the Note).  In the event the proceeds of any sale, lease or other disposition of
the Collateral hereunder are insufficient to pay all of the Secured Obligations
in full, the Debtor will be liable for the deficiency, together with interest
thereon at the maximum rate provided in the Note, and the cost and expenses of
collection of such deficiency, including (to the extent permitted by law),
without limitation, reasonable attorneys' fees, expenses and disbursements.

     14.  Waivers, etc.  The Debtor hereby waives presentment, demand, notice,
          ------------
protest and, except as is otherwise provided herein, all other demands and
notices in connection with this Agreement or the enforcement of the Lender's
rights hereunder or in connection with any Secured Obligations or any
Collateral; consents to and waives notice of the granting of renewals,
extensions of time for payment or other indulgences to the Debtor or to any
account debtor in respect of any account

                                       7
<PAGE>

receivable or to any other third party, or substitution, release or surrender of
any Collateral, the addition or release of persons primarily or secondarily
liable on any Secured Obligation or on any account receivable or other
Collateral, the acceptance of partial payments on any Secured Obligation or on
any account receivable or other Collateral and/or the settlement or compromise
thereof. No delay or omission on the part of the Lender in exercising any right
hereunder shall operate as a waiver of such right or of any other right
hereunder. Any waiver of any such right on any one occasion shall not be
construed as a bar to or waiver of any such right on any future occasion. THE
DEBTOR FURTHER WAIVES ANY RIGHT IT MAY HAVE UNDER THE CONSTITUTION OF THE STATE
OF NEW YORK, UNDER THE CONSTITUTION OF ANY STATE IN WHICH ANY OF THE COLLATERAL
MAY BE LOCATED, OR UNDER THE CONSTITUTION OF THE UNITED STATES OF AMERICA, TO
NOTICE (OTHER THAN ANY REQUIREMENT OF NOTICE PROVIDED HEREIN) OR TO A JUDICIAL
HEARING PRIOR TO THE EXERCISE OF ANY RIGHT OR REMEDY PROVIDED BY THIS AGREEMENT
TO THE LENDER AND WAIVES ITS RIGHTS, IF ANY, TO SET ASIDE OR INVALIDATE ANY SALE
DULY CONSUMMATED IN ACCORDANCE WITH THE FOREGOING PROVISIONS HEREOF ON THE
GROUNDS (IF SUCH BE THE CASE) THAT THE SALE WAS CONSUMMATED WITHOUT A PRIOR
JUDICIAL HEARING. The Debtor's waivers under this section have been made
voluntarily, intelligently and knowingly and after the Debtor has been apprized
and counseled by its attorneys as to the nature thereof and its possible
alternative rights.

     15.  Termination; Assignment, etc.  This Agreement and the security
          ----------------------------
interest in the Collateral created hereby shall terminate when all of the
Secured Obligations have been paid and finally discharged in full and no Lender
is obligated to make additional Loans under the Credit Agreement.  In such
event, the Lender agrees to execute appropriate releases of liens on the
Collateral.  No waiver by the Lender or by any other holder of Secured
Obligations of any default shall be effective unless in writing nor operate as a
waiver of any other default or of the same default on a future occasion.  In the

                                                           -----
     further represents and warrants to the Lender that Schedules A, B and C

     hereto, respectively, are true, correct and complete lists as of the date
     hereof of all Patents, Trademarks and Copyrights owned by Pledgor and that

     --------------------
     matters set forth therein as of the date hereof.

          (b) Pledgor has full corporate power, authority and legal right to
     pledge and grant a security interest in the Pledged Collateral in
     accordance with the terms of this Agreement and this Agreement has been
     duly and validly executed and delivered by Pledgor, constitutes the legal,
     valid and binding obligation of Pledgor, enforceable against Pledgor in
     accordance with its terms, subject to applicable bankruptcy, insolvency,
     reorganization, moratorium or other laws affecting creditors' rights
     generally and subject to general principles of equity, regardless of
     whether considered in a proceeding in equity or at law.

          (c) Except as set forth on Schedule E hereto and except for filings
                                     ----------
     with the Patent and Trademark Office, under the UCC and under applicable
     foreign law, no authorization, consent, approval, license, qualification or
     formal exemption from, nor any filing, declaration or registration with,
     any court (other than in connection with the exercise of judicial
     remedies), governmental agency or regulatory authority, or with any
     securities exchange or any other Person is required in connection with (1)
     the pledge by Pledgor of the Pledged Collateral pursuant to this Agreement,
     or the execution, delivery or performance by Pledgor of this Agreement, (2)
     the grant of a security interest (including the priority

                                       4
<PAGE>

     thereof when the appropriate filings have been made and accepted) in, the
     Pledged Collateral by Pledgor in the manner and for the purpose
     contemplated by this Agreement or (3) the exercise of the rights and
     remedies of the Lender created hereby.

          (d) Pledgor has made and will continue to make all necessary filings
     and recordations from time to time and use appropriate statutory notice to
     protect its interests in the Pledged Collateral, including without
     limitation, appropriate recordations of its interests in the Patents and
     Trademarks in the United States Patent and Trademark Office and in
     corresponding offices wherever it does business using such Patents and
     Trademarks throughout the world and its claims to Copyrights in the United
     States Copyright Office, in each case including exclusive licenses and as
     otherwise requested from time to time by the Lender, but in any event all
     in a manner consistent with prudent and commercially reasonable business
     practices.

          (e) Pledgor owns or has rights to use all the Pledged Collateral and
     all rights with respect to any of the foregoing used in, necessary for or
     material to Pledgor's business as currently conducted and as contemplated
     to be conducted pursuant to the Loan Documents.  To Pledgor's best
     knowledge, the use of such Pledged Collateral and all rights with respect
     to the foregoing by Pledgor does not infringe on the rights of any Person
     and, except as set forth on Schedule F attached hereto, no material claim
                                 ----------
     has been made and remains outstanding that Pledgor's use of the Pledged
     Collateral does or may violate the rights of any third person.

          (f) Upon filings and the acceptance thereof in the appropriate offices
     under the UCC and in the United States Patent and Trademark Office and the
     United States Copyright Office, this Agreement will create a valid and duly
     perfected first priority lien and security interest in the United States in
     the Pledged Collateral, subject to no Liens.

     Section 6.  Covenants.
                 ---------

          (a) On a continuing basis, Pledgor will, at the expense of Pledgor,
     subject to any prior licenses, Liens and restrictions, make, execute,
     acknowledge and deliver, and file and record in the proper filing and
     recording offices, all such instruments or documents, including, without
     limitation, appropriate financing and continuation statements, exclusive
     licenses and collateral agreements, and take all such action (limited, as
     aforesaid, if applicable) as may reasonably be deemed necessary or
     appropriate by the Lender (i) to carry out the intent and purposes of this
     Agreement, (ii) to assure and confirm to the Lender the grant or perfection
     of a security interest in the Pledged Collateral for the benefit of the
     Secured Parties, and (iii) during the continuation of an Event of Default,
     to enable

                                       5
<PAGE>

     the Secured Parties to exercise and enforce their rights and remedies
     hereunder with respect to any Pledged Collateral. Without limiting the
     generality of the foregoing, Pledgor:

     with Pledgor's obligations hereunder;

          Copyright Office with respect to any Patent, Trademark or Copyright
          material to Pledgor's business; or

               (ii) any written claim received, the institution of any
          proceeding or any materially adverse determination in any federal,
          state, local or foreign court or administrative bodies regarding
          Pledgor's claim of ownership in or right to use any of the Pledged
          Collateral, its right to register the Pledged Collateral, or its right
          to keep and maintain such registration in full force and effect;

          (D) will properly maintain and protect the Pledged Collateral to the
     extent necessary or appropriate for the conduct of Pledgor's business (as

     consistent with Pledgor's current practice in accordance with applicable
     statutory requirements;

          (E) will not grant or permit to exist any Lien upon or with respect to

     payable in respect of the Pledged Collateral, that, if not paid, could
     result in a material adverse effect, before the same shall become
     delinquent or in default, except where (a) the validity or amount thereof
     is being contested in good faith by appropriate proceedings, (b) Pledgor
     has set aside on its books adequate reserves with respect thereto in
     accordance with GAAP and (c) the failure to make payment pending such
     contest could not reasonably be expected to result in a material adverse
     effect;

          (L) will comply in all material respects with all laws, rules and
     regulations applicable to the Pledged Collateral; and

          (M) will deposit with the Lender, at such times as the Lender shall
     reasonably request, copies of all source code of all software owned by
     Pledgor as the Lender shall request which is material to the operation of
     Pledgor's business and such source code copy shall be of the most current
     version of all software and shall include all modifications and
     enhancements thereto and shall be

                                       7

     annotated so as to be easily understood by a software technician of
     reasonable proficiency.

          (b) If, before the Secured Obligations shall have been paid and
     satisfied in full in cash or cash equivalents, Pledgor shall, (1) obtain
     any rights to any additional Pledged Collateral or (2) become entitled to
     the benefit of any additional Pledged Collateral or any renewal or
     extension thereof, including any reissue, division, continuation, or
     continuation-in-part of any Patent, or any improvement on any Patent, the
     provisions of this Agreement shall automatically apply thereto and any item
     enumerated in clause 6(b)(1) or clause 6(b)(2) with respect to Pledgor
     shall automatically constitute Pledged Collateral if such would have
     constituted Pledged Collateral at the time of execution of this Agreement,
     and be subject to the assignment, Lien and security interest created by
     this Agreement without further action by any party.  Pledgor shall promptly
     provide to the Lender written notice of any of the foregoing.  Pledgor
     shall, at least once in each calendar quarter, provide written notice to
     the Lender of all applications for Patents and all applications for
     registration of Trademarks or Copyrights made during the preceding calendar
     quarter.  Pledgor agrees, promptly following the written request by the
     Lender, to confirm the attachment of the lien and security interest created
     by this Agreement to any rights described in clause 6(b)(1) or clause
     6(b)(2) above if such would have constituted Pledged Collateral at the time
     of execution of this Agreement by execution of an instrument in form
     acceptable to the Lender.

          (c) Pledgor authorizes the Lender to modify this Agreement by amending
     Schedules A, B and/or C annexed hereto to include any future Pledged
     -----------------------
     Collateral of Pledgor, including, without limitations any of the items
     listed in Section 6(b).

          (d) Pledgor shall file and prosecute diligently all applications for
     Patents, Trademarks or Copyrights now or hereafter pending that would be
     useful or beneficial to the businesses of Pledgor to which any such
     applications pertain, and to do all acts necessary to preserve and maintain
     all rights in the Pledged Collateral unless such Pledged Collateral has
     become obsolete to Pledgor's business, as reasonably determined by Pledgor
     consistent with prudent and commercially reasonable business practices.
     Any and all costs and expenses incurred in connection with any such actions
     shall be borne by Pledgor.  Except in accordance with prudent and
     commercially reasonable business practices, Pledgor shall not abandon any
     right to file a Patent, Trademark or Copyright application or any pending
     Patent, Trademark or Copyright application or any Patent, Trademark or
     Copyright without the consent of the Lender.

     Section 7.  Transfers and Other Liens.  Pledgor will not (a) sell, convey,
                 -------------------------

except for licensing in the ordinary course of business or (b) create or permit
to exist any Lien upon or with respect to any of the Pledged Collateral, except
for Liens for taxes, assessments or government charges or claims the payment of
which is not at the time required and inchoate Liens imposed by law (each of
which shall, except to the extent otherwise required by law, be subordinate to
the lien created by this Agreement) and the lien granted to the Lender under
this Agreement.

     Section 8.  Remedies upon Default.
                 ---------------------

          (a) If any Event of Default shall have occurred and be continuing, the
     Lender may to the full extent permitted by law, (1) exercise any and all
     rights as beneficial and legal owner of the Pledged Collateral, including,
     without limitation, perfecting assignment of any and all contractual rights
     and powers with respect to the Pledged Collateral and (2) sell or assign or
     grant a license to use, or cause to be sold or assigned or a license
     granted to use any or all of the Pledged Collateral (in the case of
     Trademarks, along with the goodwill associated therewith) or any part
     thereof, in each case, free of all rights and claims of Pledgor therein and
     thereto.  In accordance with such rights, the Lender shall have (A) the
     right to cause any or all of the Pledged Collateral to be transferred of
     record into the name of the Lender or its nominee and (B) the right to
     impose (i) such limitations and restrictions on the sale or assignment of
     the Pledged Collateral as the Secured Parties may deem to be necessary or
     appropriate to comply with any law, rule or regulation (federal, state or
     local) having applicability to the sale or assignment, and (ii) any
     necessary or appropriate requirements for any required governmental
     approvals or consents.

          (b) Except as provided in this Section 8 and other express notice
     provisions of the Loan Documents, Pledgor hereby expressly waives, to the
     fullest extent permitted by applicable law, any and all notices,
     advertisements, hearings or process of law in connection with the exercise
     by the Secured Parties of any of their rights and remedies hereunder.

          (c) Pledgor agrees that, to the extent notice of sale shall be
     required by law, ten (10) days' notice from the Lender of the time and
     place of any public sale or of the time after which a private sale or other
     intended disposition is to take place shall be commercially reasonable
     notification of such matters.  In addition to the rights and remedies
     provided in this Agreement and in the other Loan Documents, the Secured
     Parties shall have all the rights and remedies of a secured party under the
     UCC.

          (d) Except as otherwise provided herein, Pledgor hereby waives, to the
     fullest extent permitted by applicable law, notice or judicial hearing in
     connection with the Lender's taking possession or the Lender's disposition
     of any of the Pledged Collateral, including, without limitation, any and
     all prior notice and

                                       9
<PAGE>

     rights to a hearing for any prejudgment remedy or remedies and any such
     right which Pledgor would otherwise have under law, and Pledgor hereby
     further waives to the extent permitted by applicable law: (1) all damages
     occasioned by any such taking of possession; (2) all other requirements as
     to the time, place and terms of sale or other requirements with respect to
     the enforcement of the Secured Parties' rights hereunder; and (3) all
     rights of redemption, appraisal, valuation, stay, extension or moratorium
     now or hereafter in force under any applicable law. Any sale of, or the
     grant of options to purchase, or any other realization upon, any Pledged
     Collateral shall operate to divest all right, title, interest, claim and
     demand, either at law or in equity, of Pledgor therein and thereto, and
     shall be a perpetual bar both at law and in equity against Pledgor and
     against any and all Persons claiming or attempting to claim the Pledged
     Collateral so sold, optioned or realized upon, or any part thereof, from,
     through or under Pledgor.

     Section 9.  Application of Proceeds.  The proceeds of any Pledged
                 -----------------------
Collateral obtained pursuant to the exercise of any remedy set forth in Section
8 shall be applied, together with any other sums then held by the Lender
pursuant to this Agreement, promptly by the Lender:

          First, to the payment of all costs and expenses, fees, commissions and
          -----
     taxes of such sale, collection or other realization, including, without
     limitation, reasonable reimbursement to the Lender, and its agents and
     counsel for all expenses, fees, liabilities and advances made or incurred
     by them in connection therewith and all expenses, liabilities and advances
     made or incurred by the Lender in connection therewith, together with
     interest on each such amount at the rate then in effect under the Note;

          Second, to the payment of all other costs and expenses of such sale,
          ------
     collection or other realization, including, without limitation, reasonable
     reimbursement to the Lender and its agents and counsel for all expenses,
     fees, liabilities and advances made or incurred by them in connection
     therewith and all costs, liabilities and indebtedness made or incurred by
     the Lender in connection therewith together with interest on each such
     amount at the highest rate then in effect under the Note;

          Third, to the indefeasible payment in full in cash of the Secured
          -----
     Obligations, ratably according to the unpaid amounts thereof, without
     preference or priority of any kind among amounts so due and payable; and

          Fourth, to Pledgor, or its successors or assigns, or to whomsoever may
          ------
     be lawfully entitled to receive the same or as a court of competent
     jurisdiction may direct, of any surplus then remaining from such Proceeds.

                                       10
<PAGE>

     Section 10.  Expenses.  Pledgor will pay on demand all expenses of the
                  --------

therewith, or the administration, default or collection of the Loans or
administration, default, collection in connection with the Lender's exercise,
preservation or enforcement of any of its rights, remedies or options
thereunder, including, without limitation, reasonable fees and disbursements of
outside legal counsel or accounting, consulting, brokerage or other similar
professional fees or expenses, and any fees or expenses associated with any
travel or other costs relating to any appraisals or examinations conducted in
connection with the Secure Obligations or any Collateral therefor, and the
amount of all such expenses shall, until paid, bear interest at the rate
applicable to principal hereunder (including any default rate).

     Section 11.  No Waiver; Cumulative Remedies.
                  ------------------------------

          (a) No failure on the part of the Lender or the Secured Parties to
     exercise, no course of dealing with respect to, and no delay on the part of
     the Lender in exercising, any right, power or remedy hereunder shall
     operate as a waiver thereof; nor shall any single or partial exercise of
     any such right, power or remedy hereunder preclude any other or further
     exercise thereof or the exercise of any other right, power or remedy.  The
     remedies herein provided are cumulative and are not exclusive of any
     remedies provided by law.

          (b) In the event the Lender shall have instituted any proceeding to
     enforce any right, power or remedy under this instrument by foreclosure,
     sale, entry or otherwise, and such proceeding shall have been discontinued
     or abandoned for any reason or shall have been determined adversely to the
     Lender, then and in every such case, Pledgor and the Lender shall, to the
     extent permitted by applicable law, be restored to their respective former
     positions and rights hereunder with respect to the Pledged Collateral, and
     all rights, remedies and powers of the Lender shall continue as if no such
     proceeding had been instituted.

     Section 12.  The Lender May Perform, the Lender Appointed Attorney-in-Fact.
                  -------------------------------------------------------------
If Pledgor shall fail to do any act or thing that it has covenanted to do
hereunder or any warranty on the part of Pledgor contained herein shall be
breached, the Lender may (but shall not be obligated to) do the same or cause it
to be done or remedy any such breach, and may expend funds for such purpose.
Any and all amounts so expended by the Lender shall be paid by Pledgor promptly
upon demand therefor, with interest at the highest rate then in effect under the
Note during the period from and including the date on which such funds were so
expended to the date of repayment.  Pledgor's obligations under this Section 12
shall survive the termination of this Agreement and the discharge of Pledgor's
other obligations hereunder.  Pledgor hereby appoints the Lender its attorney-
in-fact with an interest, with full authority in the place and stead of Pledgor
and in the name of Pledgor, or otherwise, from time to time in the Lender's
reasonable

                                       11
<PAGE>

discretion to take any action and to execute any instruments consistent with the
terms of this Agreement and the other Loan Documents which the Lender may deem
necessary or advisable to accomplish the purposes of this Agreement. The
foregoing grant of authority is a power of attorney coupled with an interest and
such appointment shall be irrevocable for the term of this Agreement. Pledgor
hereby ratifies all that such attorney shall lawfully do or cause to be done by
virtue hereof.

     Section 13.  Indemnity.
                  ---------

          (a) Indemnity.  Pledgor agrees to indemnify, reimburse and hold the
              ---------
     Lender and its successors, assigns, employees, agents and servants
     (collectively, "Indemnitees") harmless from and against any and all
     liabilities, obligations, damages, injuries, penalties, claims, demands,
     actions, suits, judgments and any and all costs and expenses (including,
     without limitation, attorneys' fees and expenses and the allocated costs of
     internal counsel) of whatsoever kind and nature imposed on, asserted
     against or incurred by any of the Indemnitees in any way relating to or
     arising out of this Agreement or the other Loan Documents or in any other
     way connected with the administration of the transactions contemplated
     hereby or the enforcement of any of the terms hereof, or the preservation
     of any rights hereunder, or in any way relating to or arising out of the
     manufacture, processing, ownership, ordering, purchase, delivery, control,
     acceptance, lease, financing, possession, operation, condition, sale,
     return or other disposition, or use of the Pledged Collateral (including,
     without limitation, latent or other defects, whether or not discoverable,
     any claim for patent, trademark, trade secret or copyright infringement),
     the violation of the laws of any country, state or other governmental body
     or unit, any tort (including, without limitation, claims arising or imposed
     under the doctrine of strict liability, or for or on account of injury to
     or the death of any Person (including any Indemnitee)), or property damage,
     or contract claim; provided that Pledgor shall have no obligation to an
     Indemnitee hereunder to the extent it is finally judicially determined that
     such indemnified liabilities arise solely from the gross negligence or
     willful misconduct of that Indemnitee.  Upon written notice by any
     Indemnitee of the assertion of such a liability, obligation, damage,
     injury, penalty, claim, demand, action, judgment or suit, Pledgor shall
     assume full responsibility for the defense thereof.  If any action, suit or
     proceeding arising from any of the foregoing is brought against any
     Indemnitee, Pledgor shall, if requested by such Indemnitee, resist and
     defend such action, suit or proceeding or cause the same to be resisted and
     defended by counsel reasonably satisfactory to such Indemnitee.  Each
     Indemnitee shall, unless any other Indemnitee has made the request
     described in the preceding sentence and such request has been complied
     with, have the right to employ its own counsel (or internal counsel) to
     investigate and control the defense of any matter covered by the indemnity
     set forth in this Section 13 and the fees and expenses of such counsel
     shall be paid by Pledgor; provided that, only to the extent that no
     conflict exists between or among the

                                       12
<PAGE>

     Indemnitees as reasonably determined by the Indemnitees, Pledgor shall not
     be obligated to pay the fees and expenses of more than one counsel for all
     Indemnitees as a group with respect to any such matter, action, suit or
     proceeding.

          (b) Misrepresentations.  Without limiting the application of
              ------------------
     subsection 13(a), Pledgor agrees to pay, indemnify and hold each Indemnitee
     harmless from and against any loss, costs, damages and expenses which such
     Indemnitee may suffer, expend or incur in consequence of or growing out of
     any misrepresentation by Pledgor in this Agreement or any of the other Loan
     Documents or in any statement or writing contemplated by or made dr
     delivered pursuant to or in connection with this Agreement or any of the
     other Loan Documents.

          (c) Contributions.  If and to the extent that the obligations of
              -------------
     Pledgor under this Section 13 are unenforceable for any reason, Pledgor
     hereby agrees to make the maximum contribution to the payment and
     satisfaction of such obligations that is permissible under applicable law.

          (d) Survival.  The obligations of Pledgor contained in this Section 13
              --------
     shall survive the termination of this Agreement and the discharge of
     Pledgor's other obligations hereunder and under the other Loan Documents.

          (e) Reimbursement.  Any amounts paid by any Indemnitee as to which
              -------------
     such Indemnitee has the right to reimbursement shall constitute Secured
     Obligations secured by the Pledged Collateral.

     Section 14.  Litigation.
                  ----------

          (a) Pledgor shall have the right to commence and prosecute in its own
     name, as real party in interest, for its own benefit and at its own
     expense, such applications for protection of Pledged Collateral, suits,
     proceedings or other actions for infringement, counterfeiting, unfair
     competition, dilution or other damage as are in its reasonable business
     judgment necessary to protect the Pledged Collateral.  Pledgor shall
     promptly notify the Lender in writing as to the commencement and
     prosecution of any such actions, or threat thereof relating to the Pledged
     Collateral and shall provide to the Lender such information with respect
     thereto as may be reasonably requested.  The Lender shall provide all
     reasonable and necessary cooperation in connection with any such suit,
     proceeding or action, including, without limitation, joining as a necessary
     party.

          (b) Upon the occurrence and during the continuation of an Event of
     Default, the Lender shall have the right but shall in no way be obligated
     to file applications for protection of the Pledged Collateral and/or bring
     suit in the name

                                       13
<PAGE>

     of Pledgor, the Lender or the Lender to enforce the Pledged Collateral and
     any license thereunder; in the event of such suit, Pledgor shall, at the
     request of the Lender, do any and all lawful acts and execute any and all
     documents required by the Lender in aid of such enforcement and Pledgor
     shall promptly, upon demand, reimburse and indemnify the Lender, as the
     case may be, for all costs and expenses incurred by the Lender in the
     exercise of its rights under this Section 14. In the event that the Lender
     shall elect not to bring suit to enforce the Pledged Collateral, Pledgor
     agrees to use all measures, whether by action, suit, proceeding or
     otherwise, to prevent the infringement, counterfeiting or other diminution
     in value of any of the Pledged Collateral by others and for that purpose
     agrees to diligently maintain any action, suit or proceeding against any
     person so infringing necessary to prevent such infringement as is in the
     reasonable business judgment of Pledgor necessary to protect the Pledged
     Collateral and the Lender shall provide, at Pledgor's expense, all
     necessary and reasonable assistance to Pledgor to maintain such action.

     Section 15.  Modifications in Writing.  No amendment, modification,
                  ------------------------
supplement, termination or waiver of or to any provision of this Agreement, nor
consent to any departure by Pledgor therefrom, shall be effective unless the
same shall be in writing and signed by the Lender and, except in the case of any
such termination, waiver or consent, by the Pledgor.  Any amendment,
modification or supplement of or to any provision of this Agreement, any waiver
of any provision of this Agreement, and any consent to any departure by Pledgor
from the terms of any provision of this Agreement, shall be effective only in
the specific instance and for the specific purpose for which made or given.
Except where notice is specifically required by this Agreement or any other Loan
Document, no notice to or demand on Pledgor in any case shall entitle Pledgor to
any other or further notice or demand in similar or other circumstances.

     Section 16.  Termination; Release.  When all the Secured Obligations (other
                  --------------------
than Secured Obligations in the nature of continuing indemnitees or expense
reimbursement obligations not yet due and payable) have been paid in full and
have been terminated and the Lender and the Pledgor agree to terminate this
Agreement, this Agreement shall terminate.  Upon termination of this Agreement
the Lender shall, upon the request and at the expense of Pledgor, forthwith
assign, transfer and deliver to Pledgor against receipt and without recourse to
or warranty by the Lender, such of the Pledged Collateral to be released (in the
case of a release) as may be in the possession of the Lender and as shall not
have been sold or otherwise applied pursuant to the terms hereof, on the order
of and at the expense of Pledgor, and proper instruments (including UCC
termination statements on Form UCC-3 and documents suitable for recordation in
the United States Patent and Trademark Office, the United States Copyright
Office or similar domestic or foreign authority) acknowledging the termination
of this Agreement or the release of such Pledged Collateral, as the case may be.

                  -------------

be, if at any time any amount received by the Lender in respect of the Secured
Obligations is rescinded or must otherwise be restored or returned by the Lender
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of
Pledgor or upon the appointment of any intervenor or conservator of, or trustee
or similar official for, Pledgor or any substantial part of its properties, or
otherwise, all as though such payments had not been made.

otherwise, subject however, to the provisions of the Note.

                  --------------------
AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE

                  --------------------
law, all obligations of Pledgor hereunder shall be absolute and unconditional
irrespective of:

          (a) any bankruptcy, insolvency, reorganization, arrangement,
     readjustment, composition liquidation or the like of Pledgor or any other
     Subsidiary of Pledgor;

          (b) any lack of validity or enforceability of the Note, any other Loan
     Document, or any other agreement or instrument relating thereto;

          (c) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Secured Obligations, or any other
     amendment or waiver of or any consent to any departure from the Note, any
     other Loan Document, or any other agreement or instrument relating thereto;

          (d) any exchange, release or non-perfection of any other collateral,
     or any release or amendment or waiver of or consent to any departure from
     any guarantee, for all or any of the Secured Obligations; or

Secured Obligations under any statute or rule of law now or hereafter in effect
which provides that the exercise of any particular right or remedy as provided
for herein (by judicial proceedings or otherwise) constitutes the exclusive
means for satisfaction of the Secured Obligations or which makes unavailable any
further judgment or any other right or remedy provided for herein because the
Lender elected to proceed with the exercise of such initial right or remedy or
because of any failure by the Lender to comply with laws that prescribe
conditions to the entitlement to such subsequent judgment or the availability of
such subsequent right or remedy.  In the event that, notwithstanding the
foregoing waiver, any court shall for any reason hold that such subsequent
judgment or action is not available to the Lender, Pledgor shall not (a)
introduce in any other jurisdiction any judgment so holding as a defense to
enforcement against Pledgor of any remedy in the Note or executed in connection
with the Note or (b) seek to have such judgment recognized or entered in any
other jurisdiction, and any such judgment shall in all events be limited in
application only to the state or jurisdiction where rendered and only with
respect to the collateral referred to in such judgment.

     Section 28.  Future Advances.  This Agreement shall secure the payment of
                  ---------------
any amounts advanced from time to time pursuant to the Note.

                            STOCK PURCHASE AGREEMENT


     THIS AGREEMENT dated as of April 7,1999, among CMGI, Inc., a Delaware
corporation ("CMGI"), Engage Technologies, Inc., a Delaware corporation and a
majority- owned subsidiary of CMGI ("Engage," collectively with CMGI the
"Purchasers," and each individually a "Purchaser"), Internet Profiles
Corporation, a California corporation (the "Company"), and the stockholders of
the Company listed on Schedule 1 hereto (collectively, the "Stockholders" and
                      ----------
each a "Stockholder").

                                   WITNESSETH

     WHEREAS each of the Stockholders owns (or will own as of the Closing (as
defined) through conversion or otherwise) the number of the issued and
outstanding shares (collectively, the "Shares" and each a "Share") of the common
stock, par value $0.001 per share (the "Common Stock"), of the Company set forth
opposite such Stockholder's name and address on Schedule 1 attached hereto,
                                                ----------
which Shares in the aggregate represent at least 90% of the issued and
outstanding shares of the capital stock of the Company on a fully diluted, as-
converted basis on the date of this Agreement;

     WHEREAS Purchasers desire to acquire the Shares from the Stockholders, and
the Stockholders desire to sell the Shares to Purchasers, upon the terms and
subject to the conditions hereinafter set forth.

     NOW THEREFORE, in consideration of the foregoing and of the covenants set
forth below, the parties hereby agree as follows:


                  SECTION 1 - PURCHASE AND SALE OF THE SHARES

     1.1  Purchase and Sale.
          -----------------

          (a) For the purposes of this Agreement:

              (i) "Fully Diluted Shares" means the total number of outstanding
                   --------------------
shares of common stock of the Company as determined on a fully diluted, as
converted basis with respect to any convertible preferred stock, convertible
notes, other convertible securities, options or other rights to acquire a
capital interest in or stock of the Company; provided, however, that "Fully
Diluted Shares" shall not be deemed to include the Underwater Warrants (as
defined).  The number of Fully Diluted Shares is 59,068,868.

              (ii) "CMGI Stock Number" means, with respect to a certain dollar
                    -----------------
value, the number of shares of CMGI common stock, par value $0.01 per share
("CMGI Common Stock"), equal to such dollar value when a share of CMGI Common
<PAGE>

Stock is valued at the average of the closing prices per share of CMGI Common
Stock as reported on the NASDAQ National Market System during the twenty (20)
consecutive trading days ending on March 1, 1999.  In accordance with the
foregoing, each share of CMGI Common Stock is valued at $113.31 per share.  The
CMGI Stock Number shall be adjusted, as necessary, to reflect any stock split,
reverse stock split, stock dividend or stock combination affecting CMGI Common
Stock as a class occurring after the third trading day prior to the Closing
Date.

              (iii)  "Engage Stock Number" means, with respect to a certain
                     -------------------
dollar value, the number of shares of Engage common stock, par value $0.01 per
share ("Engage Common Stock"), valued at a pre-Closing valuation for Engage of
Two Hundred Million Dollars ($200,000,000).  There are 19,777,041 shares of
Engage Common Stock outstanding as of January 31, 1999 determined on a fully
diluted, as converted basis with respect to any convertible preferred stock,
convertible notes, other convertible securities, options or other rights to
acquire a capital interest in or stock of Engage.  In accordance with the
foregoing, each share of Engage Common Stock is valued for purposes hereof at
$10.11 per share.

          (b) Upon the terms and subject to the conditions of this Agreement, at
the Closing, each of the Stockholders agrees to sell to Purchasers, and
Purchasers agree to purchase from each of the Stockholders, all of the Shares
owned by each such Stockholder, as set forth opposite such Stockholder's name on
Schedule 1 hereto. The purchase price for each Share (the "Base Purchase Price")
- ----------
shall be an amount equal to the product of Thirty Million Dollars ($30,000,000)
and the Stockholders' Interest (as defined), less any reduction pursuant to
Section 7.3 hereof, and (in order to provide for payment by the Company,
following the Closing, of certain fees described in Section 7.3) divided by the
product of the Stockholders' Interest and the number of Fully Diluted Shares.
"Stockholders' Interest" means the aggregate percentage interest of the Fully
Diluted Shares (as used to calculate the Base Purchase Price) held by the
Stockholders.  The Base Purchase Price shall be paid in CMGI Common Stock in a
CMGI Stock Number derived from 80% of the Base Purchase Price and in Engage
Common Stock in an Engage Stock Number derived from 20% of the Base Purchase
Price (collectively, the "Initial Consideration").

              (i) Within 30 days after March 31,2000, Purchasers shall deliver
to the Stockholders' Representative (as defined below), a profit and loss
statement showing gross revenues for the Company, prepared in accordance with
generally accepted accounting principles on a basis consistent with the
accounting principles utilized in the preparation of the Company's year-end
financial statements, and including all revenues derived from the sale of
products and services of the Company, whether recorded on the books of the

to purchase Engage Common Stock in accordance with the terms of an agreement to
be signed by the optionholders so electing.  Upon such election, all rights with
respect to Company Common Stock under outstanding Company options shall
thereupon be converted into rights with respect to Engage Common Stock.
Accordingly, from and after the Closing Date, (i) each Company option so
exchanged may be exercised solely for shares of Engage Common Stock, (ii) the
number of shares of Engage Common Stock subject to each such exchanged Company
option shall be equal to the number of shares of Company Common Stock that were

by .050305, rounded down to the nearest whole number of shares of Engage Common
Stock, (iii) the per share exercise price for Engage Common Stock issuable upon
exercise of each such exchanged Company option shall be determined by dividing
the exercise price per share of Company Common Stock subject to such Company
option, as in effect immediately prior to the Closing Date, by .050305 and
rounding down the resulting exercise price to the nearest whole cent, and (iv)
all restrictions on the exercise of each such exchanged Company option shall
continue in full force and effect, and the term, exercisability, vesting
schedule and other provisions of such Company option shall otherwise remain
materially unchanged; provided, however, that each such exchanged Company option
shall be a nonstatutory stock option and not an incentive stock option.  The
parties hereto shall take all reasonable efforts to effect the exchange of
options for those optionholders electing for such exchange, as set forth in this
Section 5.12(a).

          (b) With respect to the stock options to purchase the Company's Common
Stock granted in December 1998, outside the Company's stock option plan, all
such options shall be exercised at or prior to the Closing, and holders thereof
who are accredited investors shall receive stock consideration hereunder with
respect thereto, and holders thereof who are not accredited investors shall
receive cash under a stock purchase agreement (the "Unaccredited Person Stock
Purchase Agreement") with respect thereto.

Stock granted to accredited investors who exercised early-exercise provisions

have been satisfied at or prior to Closing, the holders of the Company's Common
Stock issued pursuant thereto shall receive stock consideration hereunder with
respect thereto.

          (d) With respect to the stock options to purchase the Company's Common
Stock granted to unaccredited investors who exercised early-exercise provisions
applicable to such options and in connection with which the vesting criteria
have been satisfied at or prior to Closing, the holders of the Company's Common
Stock issued pursuant thereto shall receive options to purchase Engage Common
Stock with respect thereto as described in subsection (a) above.

          (e) With respect to the stock options to purchase the Company's Common
Stock granted to any persons who exercised early-exercise provisions applicable
to such options and in connection with which the vesting criteria have not been
satisfied at or prior to Closing, the holders of the Company's Common Stock
issued pursuant thereto shall receive options to purchase Engage Common Stock
with respect thereto as described in subsection (a) above.

          (f) With respect to the shares of the Company's Common Stock referred
to in subsections (d) and (e) above, such shares shall be cancelled and the
notes payable to the Company relating to the exercises prices therefore shall be
cancelled.

          -----------------
Date, the Purchaser shall cause to be mailed to the then-existing shareholders
of record of the Company a notice of the intention to merge (the "Merger") the
Company with a newly-created subsidiary of Engage or CMGI, and the Purchasers
shall cause the Merger to be effected within 30 days following the Closing Date.
In the Merger each outstanding share of Common Stock shall be converted into the
right to receive a pro rata share of (i) $30 million minus the aggregate Initial
Consideration (without giving effect to any reduction pursuant to Section 7.3)
and (ii) for each of the two performance goals specified in Subsections
1.1(b)(v) and 1.1(b)(vi), if such goal is met, $1.5 million minus the aggregate
Contingent Consideration paid to the Stockholders in connection therewith.

for the elimination of all series of preferred stock of the Company and the
concomitant conversion into Common Stock of all such eliminated preferred stock
and (ii) give notice of termination of all Underwater Warrants to the holders
thereof. In the event that holders of any Underwater Warrants elect to exercise
(prior to termination) such Underwater Warrants, Purchasers shall issue CMGI
Common Stock and Engage Common Stock to such holders as if such holders had so
exercised prior to the Closing Date, provided that such holders agree to be
bound by the terms of this Agreement. Anything to the contrary contained herein
notwithstanding, Stockholders shall indemnify Purchasers in full with respect to
(x) any failure to give timely notice of termination under the Underwater
Warrants and (y) the amount, if any, by which the fair market value of CMGI
Common Stock and Engage Common Stock, valued at the date of issuance (by
reference to the 20 prior trading days as relates to CMGI and the good faith
estimate of the Board of Directors as relates to Engage) issued to holders of
Underwater Warrants, or the consideration payable to such holders in the Merger
(as a result of appraisal rights or otherwise), exceeds the aggregate Exercise
Prices actually paid to the Company with respect to such Underwater Warrants in
accordance with and subject to the limitations of Section 10 herein (without
giving effect to provisions of Section 10.4 herein applicable solely to third-
party claims).

                         SECTION 10 - INDEMNIFICATION

     10.1  Survival. Notwithstanding any right of any party to fully investigate
           --------
the affairs of the other party and notwithstanding any knowledge of facts
determined or determinable by such party pursuant to such investigation or right
of investigation, each party has the right to rely fully upon the
representations, warranties, covenants and agreements of each other party given
or made in this Agreement or any Related Instrument.  All such representations,
warranties, covenants and agreements shall survive the execution and delivery
hereof and the Closing hereunder, subject to the limitations set forth herein.
Purchasers shall have no right to recovery against any Stockholder (or any
officer, director, employee or agent of a party) other than through the exercise
of the indemnification rights set forth in Sections 10.2 and 10.3, which shall
constitute the sole and exclusive remedy after the Closing Date for any breach
of any representation, warranty or covenant of the Company or any Stockholder
contained herein or in the certificates described in Sections 7.8 and 7.9
delivered pursuant hereto, other than a fraudulent or intentional breach.

     10.2  Obligation of Stockholders to Indemnify.
           ---------------------------------------

          (a) Subsequent to the Closing, each Stockholder listed on Schedule 1
                                                                    ----------
indemnifies and holds harmless the Purchasers (and their respective directors,
officers, employees, agents, affiliates and assigns) from and against all
losses, liabilities, damages, deficiencies, costs or expenses, including
interest and penalties imposed or assessed by any judicial or administrative
body and reasonable attorneys' fees, whether or not arising out of third-party
claims and including all amounts reasonably paid in investigation, defense or
settlement of the foregoing pursuant to this Section 10 (the "Losses") based
upon, arising out of or otherwise in respect of (1) any inaccuracy in or breach
of any representation, warranty or covenant of the Company contained herein or
in the certificates described in Sections 7.8 and 7.9 delivered pursuant hereto
(2) the failure to obtain the consent to the transactions contemplated hereby of
the lessor under the Loft Lease between the Company and Harrow Realty, Inc.
regarding Room 1502(A), 25 West 45th Street, New York, New York and (3) subject
to the material performance by Purchasers of the covenants contained in Section
5.13, as relates to the Merger, or otherwise in connection herewith, the failure
to obtain the consent of all holders of Common Stock or of Fully

                                       45
<PAGE>

Diluted Shares (a) for the period beginning on the Closing Date and ending on
the first anniversary of the Closing Date, up to such Stockholder's pro-rata
share (based on the Shares held by such individual as listed on Schedule 1) of
                                                                ----------
One Hundred Percent (100%) of the Initial Consideration held in Escrow and (b)
for the period beginning on the day after the first anniversary of the Closing
Date and ending on the second anniversary of the Closing Date, up to such
Stockholder's pro-rata share (based on the Shares held by such individual as
listed on Schedule 1) of Fifty Percent (50%) of the Initial Consideration
          ----------
originally held in Escrow plus Fifty Percent (50%) of any Contingent
Consideration otherwise payable to such Stockholder.

          (b) Notwithstanding the above, with respect to any indemnification
obligation arising as a result of an inaccuracy in a representation or warranty
in Sections 3.1, 3.2 or 3.3, indemnification in an amount equal to the total
consideration received by a Stockholder shall be payable by such Stockholder
without time limitation.

          (c) Limitations on Indemnification.  The limitations of Sections 10.2
              ------------------------------
with respect to a Stockholder shall not apply in the case of a fraudulent or
intentional misrepresentation or breach by that Stockholder.

     10.3  Notice and Defense of Claims. Promptly after receipt of notice of any
           ----------------------------
claim, liability or expense for which a party seeks indemnification hereunder,
such party shall give written notice thereof to the indemnifying party, but such
notification shall not be a condition to indemnification hereunder except to the
extent of actual prejudice to the indemnifying party.  The notice shall state
the information then available regarding the amount and nature of such claim,
liability or expense and shall specify the provision or provisions of this
Agreement under which the liability or obligation is asserted.  If within 30
days after receiving such notice the indemnifying party gives written notice to
the indemnified party stating that it intends to defend against such claim,
liability or expense at its own cost and expense, then defense of such matter,
including selection of counsel (subject to the consent of the indemnified party
which consent shall not be unreasonably withheld), shall be by the indemnifying
party and the indemnified party shall make no payment on such claim, liability
or expense as long as the indemnifying party is conducting a good faith and
diligent defense.  Notwithstanding the foregoing, the indemnified party shall at
all times have the right to fully participate in such defense at its own expense
directly or through counsel; provided, however, if the named parties to the
action or proceeding include both the indemnifying party and the indemnified
party and representation of both parties by the same counsel would be
inappropriate under applicable standards of professional conduct, the expense of
separate counsel for the indemnified party shall be paid by the indemnifying
party.  If no such notice of intent to dispute and defend is given by the
indemnifying party, or if such diligent good faith defense is not being or
ceases to be conducted, the indemnified party shall, at the expense of the
indemnifying party, undertake the defense of such claim,

                                       46
<PAGE>

liability or expense with counsel selected by the indemnified party, and shall
have the right to compromise or settle the same exercising reasonable business
judgment. The indemnified party shall make available all information and
assistance that the indemnifying party may reasonably request and shall
cooperate with the indemnifying party in such defense. No indemnifying party
shall without the prior written consent of the indemnified party (which consent
shall not be unreasonably withheld), settle or compromise or consent to the
entry of any judgment with respect to any pending or threatened claim, action,
suit or proceeding in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified party is an actual or potential
party to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

                          SECTION 11 - MISCELLANEOUS

     11.1  Material Adverse Change. All references to a party or the business of

<PAGE>

the correct amount of Sub Taxes due in respect of the Consolidated Returns is
billed to and paid by Sub:

     (a)  An estimate of the amount of such Sub Taxes due, which estimate shall
be determined in good faith and shall reflect amounts, if any, previously paid
by Sub with respect to Sub Taxes through the Closing Date, shall be billed to
Sub and paid to Parent prior to the Closing Date.

     (b)  Upon filing of the Consolidated Returns for the taxable year which
shall include the period commencing on August 1 and ending on the Closing Date,
either

          (i)  the unpaid amount, if any, of Sub Taxes due in respect of such
Consolidated Returns shall be billed to Sub, and Sub or its designee shall pay
such amount to Parent within 30 days after receiving written notice from Parent
of such amount, or,

          (ii)  if the amount of such Sub Taxes paid to Parent, if any, exceeds
the amount of the Sub Taxes due in respect of such Consolidated Returns, Parent
or its designee shall pay such excess to Sub or its designee within 30 days
after filing the Consolidated Returns for the taxable year which includes the
Closing Date.

     (c)  Sub Taxes due in respect of Consolidated Returns shall be determined
in accordance with (i) the method set forth in Section 1552(a)(1) of the Code
and U.S. Federal Income Tax Regulation Sections 1.1552-1(a)(1) and 1.1552-1(b),
(ii) none of the three methods of allocation under Section 1.1502-33(d)
(sometimes referred to as the three "Complementary Methods"), and (iii) the
practices of the parties for Tax periods ended prior to the Closing Date.

     (d)  Except as provided in Section 3.7 and the last sentence of this
subsection (d), no party shall have any obligation to make any payments to
another party for the use of such other party's Tax attributes pursuant to U.S.
Federal Income Tax Regulation Section 1.1502-33(d), or otherwise.
Notwithstanding the preceding sentence, Parent shall be required to reimburse
Sub for any payments required to be made in respect of periods ending on or
before the Closing Date by Sub to Sumitomo pursuant to Section 3.4.1 of the
License Agreement between Sub and Sumitomo dated as of July 31, 1998.

     Section 3.2   Subject to the provisions of Section 3.1, Parent shall be
liable for any and all Sub Taxes in respect of all Consolidated Returns due or
payable by Parent for any taxable year or Tax period ending on or before the
Closing Date.

     Section 3.3   Subject to the provisions of Section 3.1, Sub and Sub
Subsidiaries shall be liable for (i) any and all Sub Taxes in respect of
Consolidated Returns due or payable to Parent by Sub under Section 3.1, and (ii)
any and all Taxes (other than Sub Taxes in respect of Consolidated Returns)
<PAGE>

due or payable by Sub or Sub Subsidiaries for any taxable year or Tax period
(whether ending before, on or after the Closing Date).

     Section 3.4   Any Taxes (other than ad valorem, personal property and real
property Taxes) for any Tax period beginning before the Closing Date and ending
after the Closing Date shall be apportioned between Sub as a member of the
Parent Group and Sub as a separate company which is not a member of the Parent
Group, respectively, based on the actual operations of Sub and/or Sub
Subsidiaries, as the case may be, during the portion of such period ending on
the Closing Date, and the portion of such period beginning on the day following
the Closing Date, and each portion of such period shall be deemed to be a Tax
period subject to the provisions of Sections 3.2 and 3.3.  In the case of ad
valorem, personal property and real property Taxes such apportionment shall be
on a per diem basis.

     Section 3.5   Sub shall file or cause to be filed all required state,
local and foreign non-Consolidated Returns with respect to Sub and Sub
Subsidiaries for the Tax period beginning before the Closing Date and ending
after the Closing Date, and any such unfiled Tax Returns for periods ending on
or before the Closing Date, and Sub shall pay or cause its Subsidiaries to pay
all Taxes shown as due on any such Tax Returns.

     Section 3.6   Any refunds or credits of Sub Taxes in respect of
Consolidated Returns for any taxable year or Tax period ending on or before the
Closing Date shall be for the account of Parent and Parent Subsidiaries.  Any
refunds or credits of Taxes (other than Sub Taxes in respect of Consolidated
Returns) paid by Sub or Sub Subsidiaries for any taxable year or Tax period
(whether ending before, on or after the Closing Date) shall be for the account
of Sub and its Subsidiaries.

     Section 3.7

     (a)  Parent shall promptly pay to Sub the amount of any incremental Tax
savings generated by (i) a deduction, credit or exclusion that (A) is actually
realized by the Parent Group with respect to Taxes for a taxable period ending
on or before the Closing Date and (B) relates to or is based on an item that is
the basis for a similar deduction, credit or exclusion taken on a Return with
respect to Taxes of Sub or Sub Subsidiaries for a taxable period ending after
