    Because this is only a summary, it does not contain all of the information

                                 NaviSite, Inc.

    NaviSite is an Internet application service provider offering Web site and
application hosting and management services. Our Internet application service
offerings allow businesses to outsource the deployment, configuration, hosting,
management and support of their Web sites and Internet applications in a cost-
effective and rapid manner. Our focus on enhanced management services, beyond
basic co-location services, allows us to meet the expanding needs of businesses
as their Web sites and Internet applications become more complex. We also
provide our customers with access to our state-of-the-art data centers and the
benefit of our direct private transit Internet connections to major Internet
backbone providers. We only use direct private transit Internet connections,
which differentiates our network infrastructure from that of most of our
competitors. These connections increase reliability and download speeds. Our
enhanced, integrated services enable our clients to realize the following key
benefits.

  .   Cost-Effective Application Services. Our scalable infrastructure,
      repeatable Internet application services and hosting and management
      expertise enable us to offer our customers application services on a
      cost-effective basis.

  .   Rapid Deployment. We are able to rapidly deploy Internet applications,
      allowing our customers to quickly launch Web sites and Internet
      applications, often in a matter of weeks.

  .   High-Performance, World-Class Infrastructure. Our infrastructure has
      been designed expressly to meet the more demanding technical
      requirements of increasingly sophisticated Web sites and Internet
      applications.

    The scalability of our infrastructure and cost-effectiveness of our
services allow us to offer a comprehensive suite of services to meet the
current and future hosting and management needs of our customers. Our suite of
service offerings includes:

  .   Web site and Internet application hosting, enabling access to our
      state-of-the-art data centers, bandwidth and basic back-up, storage and
      monitoring services;

  .   Enhanced server management, providing custom reporting, hardware
      options, load balancing and mirroring, system security, advanced back-
      up options, remote management and the services of our business solution
      managers;

  .   Specialized application management, providing management of e-commerce
      and other sophisticated applications and their underlying services,
      including ad-serving, streaming, databases and transaction processing;
      and

  .   Application rentals and related consulting and other professional
      services.

    Since our inception, we have experienced operating losses and negative cash
flows for each quarterly and annual period. We expect to continue to incur
operating losses for at least the next three years. In addition, the market we
serve is highly competitive, and our revenue could be adversely affected by
increased competition. To date, a material portion of our revenue has been
derived from CMGI, Inc. and entities in which CMGI holds an equity interest.
CMGI and these CMGI affiliates accounted for 62% of our revenue for the quarter
ended July 31, 1999 as compared to 90% of our revenue for the quarter ended
July 31, 1998.

    The dramatic growth in Internet usage in recent years, combined with the
Internet's enhanced functionality, accessibility and security, has made the
Internet increasingly attractive to businesses as a medium for communication
and commerce. As more businesses have incorporated the Internet into their
business strategy, a growing number of them have chosen to outsource Internet
application development, implementation and support, particularly the hosting
and management of their Web sites and Internet applications. Forrester
Research, Inc., a leading market research firm, has estimated that the market
for managed Web site hosting in the United States will grow from less than $1.0
billion in 1998 to over $14.0 billion in 2003. In January 1998, Forrester
Research estimated that the market for branded application outsourcing services
in the United States will grow to $21.1 billion by 2001.

    Our objective is to be the leading Internet application service provider.
We plan to achieve this goal by continuing to enhance and leverage our
expertise, service offerings and infrastructure to provide customers with
integrated, reliable and secure Internet-based business solutions. Key elements
of our strategy are to:

  .   expand and vary the applications and management services we offer to
      our customers;

  .   offer multiple service levels to customers;

  .   increase awareness of the NaviSite brand and associate it with the
      highest quality solutions and service;

  .   maintain the competitive advantage that our infrastructure and
      expertise provide;

  .   continue to leverage and develop key industry relationships;

  .   take advantage of foreign market opportunities; and

  .   continue to pursue focused, complementary acquisitions.

    CMGI will own approximately 72.1% of our outstanding common stock upon
completion of this offering. Accordingly, CMGI will have the power, acting
alone, to elect a majority of our board of directors and will have the ability
to determine the outcome of any corporate actions requiring stockholder
approval, regardless of how our other stockholders may vote. CMGI may exercise
its voting power by written consent, without convening a meeting of the
stockholders, meaning that CMGI will be able to effect a sale or merger of
NaviSite without prior notice to, or the consent of, our other stockholders.
CMGI's ownership may have the effect of delaying, deferring or preventing a
change in control of NaviSite. CMGI's interests could conflict with the
interests of our other stockholders.

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

    We were incorporated in Delaware in December 1998. At that time, we
received a contribution of assets from our predecessor, NaviSite Internet
Services Corporation. NaviSite Internet Services Corporation was incorporated
in Delaware in February 1997 under the name CMG Information Technology, Inc.
and changed its name to NaviSite Internet Services Corporation in May 1997. Our
principal investors include CMGI, Dell Computer Corporation and Microsoft
Corporation.

    Our principal executive offices are located at 100 Brickstone Square,
Andover, Massachusetts 01810, and our telephone number is (978) 552-3300. Our
Web site address is www.navisite.com. The information on our Web site is not
incorporated by reference into this prospectus and should not be considered as
part of this prospectus.

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

    Except as otherwise noted, the number of shares outstanding upon completion
of this offering:

  .   gives effect to the conversion of approximately $12,257,000 of
      indebtedness to CMGI into 111,424 shares of Series B convertible
      preferred stock prior to the completion of this offering;

  .   gives effect to the conversion of all outstanding shares of convertible
      preferred stock into an aggregate of 21,861,075 shares of common stock
      upon completion of this offering;

  .   does not reflect the exercise, in October 1999, of options for the
      purchase of 22,996 shares of common stock; and
  .   assumes no exercise of the underwriters' over-allotment option.

                                  RISK FACTORS

    You should carefully consider the following risks before making an
investment decision. Our financial condition and operating results could be
materially adversely affected by any of the risks set forth below. The market
price of our common stock could decline due to any of these risks, and you
could lose all or part of your investment. You also should refer to the other
information set forth in this prospectus, including our consolidated financial
statements and the accompanying notes appearing elsewhere in this prospectus.

                Risks Related to Our Company and Our Operations

We have a history of operating losses and expect future losses

    We cannot assure you that we will ever achieve profitability on a quarterly
or annual basis or, if we achieve profitability, that it will be sustainable.
We were organized in 1996 by CMGI, Inc., formerly known as CMG Information
Services, Inc., to support the networks and host the Web sites of CMGI and a
number of CMGI affiliates. It was not until the Fall of 1997 that we began
providing Web site hosting and Internet application management services to
companies unaffiliated with CMGI. Since our inception in 1996, we have
experienced operating losses and negative cash flows for each quarterly and
annual period. As of July 31, 1999, we had an accumulated deficit of $34.7
million. The income potential of our business is unproven, and our limited
operating history makes it difficult to evaluate our prospects. We anticipate
increased expenses as we continue to expand and improve our infrastructure,
invest in additional applications, enhance our application management
expertise, expand our sales and marketing efforts and pursue additional
industry relationships. As a result, we expect to incur operating losses for at
least the next three years.

Fluctuations in our quarterly operating results may negatively impact our stock
price

    Our quarterly operating results may fluctuate significantly in the future
as a result of a variety of factors, many of which are outside our control.
These factors include:

  .   the demand for and market acceptance of our Web site and Internet
      application hosting and management services;

  .   our ability to develop, market and introduce new services on a timely
      basis;

  .   downward price adjustments by our competitors;

  .   changes in the mix of services provided by our competitors;

  .   technical difficulties or system downtime affecting the Internet
      generally or our hosting operations specifically;

  .   our ability to meet any increased technological demands of our
      customers;

  .   the amount and timing of costs related to our marketing efforts and
      service introductions; and

  .   economic conditions specific to the Internet application service
      provider industry.

Our operating results for any particular quarter may fall short of our
expectations or those of investors or securities analysts. In this event, the
market price of our common stock would be likely to fall.

Our principal stockholder will continue to control us and may have interests
that conflict with those of our other stockholders

    As of August 31, 1999, CMGI, through its ownership of NaviSite Internet
Services Corporation, beneficially owned approximately 89.6% of our outstanding
common stock and, upon completion of this offering, will beneficially own
approximately 72.1% of our outstanding common stock. Accordingly, CMGI will
continue to have the power, acting alone, to elect a majority of our board of
directors and will have the ability to determine the outcome of any corporate
actions requiring stockholder approval, regardless of how our other

                                       7
<PAGE>

stockholders may vote. Under Delaware law, CMGI may exercise its voting power
by written consent, without convening a meeting of the stockholders, meaning
that CMGI will be able to effect a sale or merger of NaviSite without prior
notice to, or the consent of, our other stockholders. CMGI's interests could
conflict with the interests of our other stockholders. The possible need of
CMGI to maintain control of NaviSite in order to avoid becoming a registered
investment company could influence future decisions by CMGI as to the
disposition of any or all of its ownership position in NaviSite. CMGI would be
subject to numerous regulatory requirements with which it would have difficulty
complying if it were required to register as an investment company. As a
result, CMGI may be motivated to maintain at least a majority ownership
position in NaviSite, even if other stockholders of NaviSite might consider a
sale of control of NaviSite to be in their best interests. As long as it is a
majority stockholder, CMGI has contractual rights to purchase shares in any
future financing of NaviSite, other than this offering, sufficient to maintain
its majority ownership position. CMGI's ownership may have the effect of
delaying, deferring or preventing a change in control of our company 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 significant portion of our revenue is generated by CMGI and companies
affiliated with CMGI, and the loss of this revenue would substantially impair
the growth of our business

    A significant portion of our revenue currently is generated by services
provided to CMGI and CMGI affiliates, and we anticipate that we will continue
to receive a significant portion of our revenue in the future from CMGI and
CMGI affiliates. CMGI and CMGI affiliates accounted for 96% of our revenue in
fiscal 1998 and 67% of our revenue in fiscal 1999. We cannot assure you that
revenues generated by CMGI and CMGI affiliates will continue or that we will be
able to secure business from unaffiliated customers to replace these revenues
in the future. The loss of revenue from CMGI and CMGI affiliates, or our
inability to replace this operating revenue, would substantially impair the
growth of our business. A more detailed discussion of our customer
relationships with CMGI and its affiliates is included in this prospectus under
the headings "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Overview" and "Certain Transactions--Relationship and
Transactions between NaviSite and CMGI, Inc."

Our ability to grow our business would be substantially impaired if we were
unable to obtain, on commercially reasonable terms, certain equipment that is
currently provided under leases executed or guaranteed by CMGI

    Certain of the equipment that we use or provide to our customers for their
use in connection with our services is provided under leases executed or
guaranteed by CMGI. If CMGI discontinues this practice, which it could do at
any time, we or our customers would have to obtain this equipment directly, and
we cannot assure you that we or our customers could do so on similar financial
terms. Our ability to grow our business would be substantially impaired if we
or our customers were unable to obtain this equipment on commercially
reasonable terms. A more detailed discussion of our other arrangements with
CMGI and its affiliates is included in this prospectus under the heading
"Certain Transactions--Relationship and Transactions between NaviSite and CMGI,
Inc."

If the growth of the market for Internet commerce and communication does not
continue, there may be insufficient demand for our services, and as a result,
our business strategy may not be successful

    The increased use of the Internet for retrieving, sharing and transferring
information among businesses and consumers has developed only recently, and the
market for the purchase of products and services over the Internet is new and
emerging. If acceptance and growth of the Internet as a medium for commerce and
communication does not continue, our business strategy may not be successful
because there may not be a continuing market demand for our Web site and
Internet application hosting and management services. In addition, in order for
the market for our services to grow, consumers who have historically purchased
and communicated through traditional means must elect to purchase products and
services and conduct their communication online. These transitions must
continue to ensure a growing market for our Web site and Internet application
hosting and management services.

                                       8
<PAGE>

Our growth could be substantially limited if the market for Internet
application services fails to develop or if we cannot achieve broad market
acceptance

    The market for Internet application services has only developed recently
and is evolving rapidly. There is significant uncertainty as to whether the
Internet application service market will ultimately prove to be viable or, if
it becomes viable, that it will continue to grow. Historically, businesses have
been reluctant to outsource the hosting and management of sophisticated
applications and have considered third-party service vendors to be unequipped
to manage Internet applications critical to their businesses. If the market for
outsourced system and network management of Web sites and Internet applications
fails to develop, or develops more slowly than we expect, or if our Web site
and Internet application hosting and management services do not achieve broad
market acceptance, our growth could be substantially limited.

Our ability to successfully market our services could be substantially impaired
if we are unable to deploy new Internet applications or if new Internet
applications deployed by us prove to be unreliable, defective or incompatible

    We cannot assure you that we will not experience difficulties that could
delay or prevent the successful development, introduction or marketing of
Internet application services in the future. If any newly introduced Internet
applications suffer from reliability, quality or compatibility problems, market
acceptance of our services could be greatly hindered and our ability to attract
new customers could be adversely affected. We cannot assure you that new
applications deployed by us will be free from any reliability, quality or
compatibility problems. If we incur increased costs or are unable, for
technical or other reasons, to host and manage new Internet applications or
enhancements of existing applications, our ability to successfully market our
services could be substantially impaired.

The market we serve is highly competitive, and as an early stage company, we
may lack the financial and other resources, expertise or capability needed to
capture increased market share

    We compete in the Internet application service market. This market is
rapidly evolving, highly competitive and likely to be characterized by an
increasing number of market entrants and by industry consolidation. We believe
that participants in our market must grow rapidly and achieve a significant
presence to compete effectively. As an early stage company, our business is not
as developed as that of many of our competitors. For example, our facilities
currently have limited growth capacity and we have a significantly smaller
number of customers than many of the companies that compete in our market. We
estimate that the growth capacity of our facilities may be sufficient only for
the next two years. Insufficient growth capacity in our facilities could impair
our ability to achieve rapid growth through an increase in our customer base.
Moreover, many of our competitors have substantially greater financial,
technical and marketing resources, greater name recognition and more
established relationships in the industry than we have. We may lack the
financial and other resources, expertise or capability needed to capture
increased market share in this environment in the future. A more detailed
discussion regarding the competition we face is included in this prospectus
under the heading "Business--Competition."

Any interruptions in, or degradation of, our private transit Internet
connections could result in the loss of customers or hinder our ability to
attract new customers

    Our customers rely on our ability to move their digital content as
efficiently as possible to the people accessing their Web sites and Internet
applications. We utilize our direct private transit Internet connections to
major backbone providers as a means of avoiding congestion and resulting
performance degradation at public Internet exchange points. We rely on these
telecommunications network suppliers to maintain the operational integrity of
their backbones so that our private transit Internet connections operate
effectively. Any interruptions in, or degradation of, our private transit
Internet connections could result in the loss of customers or hinder our
ability to attract new customers.

                                       9
<PAGE>

Increased costs associated with our private transit Internet connections could
result in the loss of customers or significant increases in our operating costs

    Our private transit Internet connections are already more costly than
alternative arrangements commonly utilized to move Internet traffic. If our
providers increase the pricing associated with utilizing their bandwidth, we
may be required to identify alternative methods to distribute our customers'
digital content. We cannot assure you that our customers will continue to be
willing to pay the higher costs associated with direct private transit or that
we could effectively move to another network approach. If we are unable to
access alternative networks to distribute our customers' digital content on a
cost-effective basis or to pass any additional costs on to our customers, our
operating costs would increase significantly.

If we are unable to maintain existing and develop additional relationships with
Internet application software vendors, the sale, marketing and provision of our
Internet application services may be unsuccessful

    We believe that to penetrate the market for our Web site and Internet
application hosting and management services we must maintain existing and
develop additional relationships with industry-leading Internet application
software vendors and other third parties. We license or lease our software
applications from Internet application software vendors. The loss of any of
these applications could materially impair our ability to provide services to
our customers or require us to obtain substitute software applications of lower
quality or performance standards or at greater cost. In addition, because we
generally license applications on a non-exclusive basis, our competitors may
license and utilize the same software applications. In fact, many of the
companies with which we have strategic relationships currently have, or could
enter into, similar license agreements with our competitors or prospective
competitors. We cannot assure you that software applications will continue to
be available to us from Internet application software vendors on commercially
reasonable terms. If we are unable to identify and license software
applications which meet our targeted criteria for new application
introductions, we may have to discontinue or delay introduction of services
relating to these applications.

We purchase key components of our infrastructure from a limited number of
suppliers, and our inability or failure to obtain these components in a timely
manner could result in sustained equipment failure and a loss of revenue

    We purchase from a limited number of suppliers key components of our
infrastructure, including networking equipment, that are available only from
limited sources in the quantities and with the quality that we demand. For
example, we purchase most of the routers and switches used in our
infrastructure from Cisco Systems Inc. and most of the intelligent Web
switching technology from ArrowPoint Communications Inc. We cannot assure you
that we will have the necessary hardware or parts on hand or that our suppliers
will be able to provide them in a timely manner in the event of equipment
failure. Our inability or failure to obtain the necessary hardware or parts on
a timely basis could result in sustained equipment failure and a loss of
revenue due to customer loss or claims for service credits under our service
level guarantees.

Our inability to scale our infrastructure or otherwise manage our anticipated
growth and the related expansion of our operations could result in decreased
revenue and continued operating losses

    We have experienced rapid growth in our service offerings and our customer
base. As of July 31, 1998, we were a Web site hosting provider with
approximately 51 customers. As of July 31, 1999, we were providing Web site and
Internet application hosting and management services to approximately 126
customers. In order to service our growing customer base, we will need to
continue to improve and expand our network infrastructure, in particular
through the expansion of one of our existing data centers and the construction
of new data centers. The ability of our network to connect and manage a
substantial number of customers at high transmission speeds while maintaining
superior performance is largely unproven. If our network infrastructure is not
scalable, we may not be able to provide our services to additional customers,
which would result in decreased revenue.

                                       10
<PAGE>

    In addition, between July 31, 1998 and July 31, 1999, we increased the
number of our employees from 86 to 201. This growth has placed, and likely will
continue to place, a significant strain on our financial, management,
operational and other resources. To effectively manage our anticipated growth,
we will be required to continue to enhance our operating and financial
procedures and controls, to upgrade or replace our operational, financial and
management information systems and to attract, train, motivate, manage and
retain key employees. If we are unable to effectively manage our rapid growth,
we could experience continued operating losses.

You may experience additional dilution because our historical source of funding
is expected to change, and other funding may not be available to us on
favorable terms, if at all

    CMGI has historically funded our operations as needed, increasing our
obligations to CMGI and allowing us to maintain a zero-balance cash account. We
expect this source and manner of funding to continue until completion of this
offering. At that time, we expect that our net obligations to CMGI, together
with all convertible preferred stock held by CMGI, will be converted into
common stock at a ratio of ten shares of common stock for each outstanding
share of preferred stock. We do not expect to borrow funds from CMGI after
completion of this offering.

    After completion of, and the application of the net proceeds from, this
offering, we may need to raise additional funds. We cannot assure you that
additional financing will be available on terms favorable to us, if at all. If
adequate funds were not available or were not available on acceptable terms,
our ability to respond to competitive pressures would be significantly limited.
Moreover, if additional funds are raised through the issuance of equity or
convertible debt securities, your percentage ownership in us will be reduced,
and you may experience additional dilution.

Our network infrastructure could fail, which would damage our ability to
provide guaranteed levels of service and could result in significant operating
losses

    To provide our customers with guaranteed levels of service, we must operate
our network infrastructure on a 24-hour-a-day, seven-day-a-week basis without
interruption. In order to operate in this manner, we must protect our network
infrastructure, equipment and customer files against damage from human error,
natural disasters, unexpected equipment failure, power loss or
telecommunications failures, sabotage or other intentional acts of vandalism.
Even if we take precautions, the occurrence of a natural disaster, equipment
failure or other unanticipated problem at one or more of our data centers could
result in interruptions in the services we provide to our customers. We cannot
assure you that our disaster recovery plan will address all, or even most, of
the problems we may encounter in the event of such a disaster.

    We have experienced service interruptions in the past, and any future
service interruptions could:

  .   require us to spend substantial amounts of money to replace equipment
      or facilities;

  .   entitle customers to claim service credits under our service level
      guarantees;

  .   cause customers to seek damages for losses incurred; or

  .   make it more difficult for us to attract new customers or enter into
      additional strategic relationships.

Any of these occurrences could result in significant operating losses.

The misappropriation of our proprietary rights could result in the loss of our
competitive advantage in the market

    We rely on a combination of trademark, service mark, copyright and trade
secret laws and contractual restrictions to establish and protect our
proprietary rights. We do not own any patents that would prevent or inhibit
competitors from using our technology or entering our market. We cannot assure
you that the contractual arrangements or other steps taken by us to protect our
proprietary rights will prove sufficient to

                                       11
<PAGE>

prevent misappropriation of our proprietary rights or to deter independent,
third-party development of similar proprietary assets. In addition, we provide
our services in other countries where the laws may not afford adequate
protection for our proprietary rights. If our proprietary rights are
misappropriated, we may lose our competitive advantage in the market.

Third-party infringement claims against our technology suppliers, our customers
or us could result in disruptions in service, the loss of customers or costly
and time consuming litigation

    We license or lease most technologies used in the Internet application
services that we offer. Our technology suppliers may become subject to third-
party infringement claims which could result in their inability or
unwillingness to continue to license their technology to us. We expect that we
and our customers increasingly will be subject to third-party infringement
claims as the number of Web sites and third-party service providers for Web-
based businesses grows. In addition, we have received notices alleging that our
service marks infringe the trademark rights of third parties. We cannot assure
you that third parties will not assert claims against us in the future or that
these claims will not be successful. Any infringement claim as to our
technologies or services, regardless of its merit, could result in delays in
service, installation or upgrades, the loss of customers or costly and time-
consuming litigation, or require us to enter into royalty or licensing
agreements.

The loss of key officers and personnel could impair our ability to successfully
execute our business strategy, because we substantially rely on their
experience and management skills, or could jeopardize our ability to continue
to provide service to our customers

    We believe that the continued service of key personnel, including Joel B.
Rosen, our recently elected Chief Executive Officer, and Robert B. Eisenberg,
our founder and President, is a key component of the future success of our
business. None of our key officers or personnel is currently a party to an
employment agreement with us. This means that any officer or employee can
terminate his or her relationship with us at any time. In addition, we do not
carry life insurance for any of our key personnel to insure our business in the
event of their death. The loss of any of our key officers or personnel could
impair our ability to successfully execute our business strategy, because we
substantially rely on their experience and management skills.

    In addition, the loss of key members of our sales and marketing teams or
key technical service personnel could jeopardize our positive relations with
our customers. Any loss of key technical personnel would jeopardize the
stability of our infrastructure and our ability to provide the guaranteed
service levels our customers expect.

If we fail to attract and retain additional skilled personnel, our ability to
provide Web site and Internet application management and technical support may
be limited, and as a result, we may be unable to attract customers and grow our
business

    We believe that our ability to attract, train, motivate and retain highly
skilled technical, managerial and sales personnel, particularly in the areas of
Web site and Internet application management and technical support, is
essential to our future success. Our business requires individuals with
significant levels of Internet application expertise, in particular to win
consumer confidence in outsourcing the hosting and management of mission-
critical applications. Competition for such personnel is intense, and qualified
technical personnel are likely to remain a limited resource for the foreseeable
future. Locating candidates with the appropriate qualifications, particularly
in the desired geographic location, can be costly and difficult. We may not be
able to hire the necessary personnel to implement our business strategy, or we
may need to provide higher compensation to such personnel than we currently
anticipate. If we fail to attract and retain sufficient numbers of highly
skilled employees, our ability to provide Web site and Internet application
management and technical support may be limited, and as a result, we may be
unable to attract customers and grow our business.


                                       12
<PAGE>

Any future acquisitions we make of companies or technologies may result in
disruptions to our business or distractions of our management due to
difficulties in assimilating acquired personnel and operations

    Our business strategy contemplates future acquisitions of complementary
businesses or technologies. If we do pursue additional acquisitions, our risks
may increase because our ongoing business may be disrupted and management's
attention and resources may be diverted from other business concerns. In
addition, through acquisitions, we may enter into markets or market segments in
which we have limited prior experience.

    Once we complete an acquisition, we will face additional risks. These risks
include:

  .   difficulty assimilating acquired operations, technologies and
      personnel;

  .   inability to retain management and other key personnel of the acquired
      business; and

  .   changes in management or other key personnel that may harm
      relationships with the acquired business's customers and employees.

    In addition, for at least the next two years, our acquisitions must be
accounted for using the purchase method of accounting, which could result in
unfavorable accounting for our acquisitions. We cannot assure you that any
acquisitions will be successfully identified and completed or that, if one or
more acquisitions are completed, the acquired business, assets or technologies
will generate sufficient revenue to offset the associated costs or other
adverse effects.

The international market for our services is unproven, and as a result, the
revenue generated by any current or future international operations may not be
adequate to offset the expense of establishing and maintaining those operations

    One component of our long-term strategy is to expand into international
markets. The international market for Web site and Internet application hosting
and management services is unproven, and we cannot assure you that we will be
able to market, sell and provide our services successfully outside the United
States. We could suffer significant operating losses if the revenue generated
by any current or future international data center or other operations is not
adequate to offset the expense of establishing and maintaining those
international operations.

We face risks inherent in doing business in international markets which could
adversely affect the success of our international operations

    There are risks inherent in doing business in international markets,
including different regulatory requirements, trade barriers, challenges in
staffing and managing foreign operations, currency risk, different technology
standards, different tax structures which may adversely impact earnings,
different privacy, censorship and service provider liability standards and
regulations and foreign political and economic instability, any of which could
adversely affect the success of our international operations.

Problems relating to the "Year 2000 issue" could disrupt our operations,
resulting in lost revenue and increased operating costs

    Because we offer computer-related services and because of the business-
critical nature of many of our customers' applications, our risk of lawsuits
related to Year 2000 issues is likely to be greater than that of companies in
some other industries. Our worst case scenario regarding the Year 2000 issue
involves the complete or partial failure of one or more computer systems or
software products that underlie or comprise our services. A failure of this
kind could cause service interruptions or disruptions for one or more of our
customers. This scenario could arise as a result of a failure by us or our
product or service vendors to identify or effectively address Year 2000
problems in these systems or products. For example, Year 2000 patches provided
to us by key software or hardware vendors for customer servers or network
devices could fail, causing customer outages or degraded network performance.
Alternatively, patches provided by third parties for our desktop computers
could fail, impeding network access or compromising network performance.

                                       13
<PAGE>

    We confront the Year 2000 problem in several contexts:

    Our Facilities and Services. Because our network infrastructure
incorporates components from multiple hardware and software providers, we may
be unable to determine whether any of these components will cause unexpected
Year 2000 problems or whether different components will interact in a way that
causes malfunctions. In most cases, we do not independently verify through
testing the Year 2000 compliance of vendors' products, and we cannot offer any
assurance that vendors' guarantees, if and when provided, are true or
sufficient or that we will not encounter Year 2000 compliance problems
associated with those products. While we expect that our network infrastructure
and all other material components of our facilities will be Year 2000 compliant
on or before December 1, 1999, we cannot assure you that we will meet this goal
or that we will not discover any compliance problems in the future. Our failure
to adequately address Year 2000 compliance issues in our network infrastructure
could result in claims of mismanagement, misrepresentation or breach of
contract and related litigation, which could be costly and time-consuming for
us to defend.

    Our Customers. We also face risks from customer-provided hardware or
software that we host in our data centers. The failure of our customers and
third-party providers to ensure that this hardware and software is Year 2000
compliant could result in unforeseen problems within our network
infrastructure, which could result in lost revenue and increased operating
costs. In addition, we cannot give any assurances that our customers will
upgrade their internal networks which interface with our network infrastructure
or will otherwise provide appropriate remediation for Year 2000 compliance.

    Our Suppliers. We cannot assure you that we will be able to provide our
services and maintain our operations if we are unable to obtain products,
services or systems that are Year 2000 compliant when we need them. In
addition, if vendors and service providers cannot deliver their products
because of their own Year 2000 compliance problems, we could experience
increased operating costs and lost revenue.

    Information on our state of readiness, costs and contingency plans
regarding the Year 2000 issue is included in this prospectus under the heading
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Considerations."

                     Risks Related to the Internet Industry

The emergence and growth of a market for our Internet application services will
be impaired if third parties do not continue to develop and improve the
Internet infrastructure

    The recent growth in the use of the Internet has caused frequent periods of
performance degradation, requiring the upgrade of routers and switches,
telecommunications links and other components forming the infrastructure of the
Internet by Internet service providers and other organizations with links to
the Internet. Any perceived degradation in the performance of the Internet as a
means to transact business and communicate could undermine the benefits and
market acceptance of our Web site and Internet application hosting and
management services. Our services are ultimately limited by, and dependent
upon, the speed and reliability of hardware, communications services and
networks operated by third parties. Consequently, the emergence and growth of
the market for our Internet application services will be impaired if
improvements are not made to the entire Internet infrastructure to alleviate
overloading and congestion.

We could be subject to increased operating costs, as well as claims, litigation
or other potential liability, in connection with risks associated with Internet
security and the security of our systems

    A significant barrier to the growth of e-commerce and communications over
the Internet has been the need for secure transmission of confidential
information. Several of our Internet application services utilize encryption
and authentication technology licensed from third parties to provide the
protections necessary to effect secure transmission of confidential
information. We also rely on security systems designed by third parties and the
personnel in our network operations centers to secure our data centers. Any
unauthorized access,

                                       14
<PAGE>

computer viruses, accidental or intentional actions and other disruptions could
result in increased operating costs. For example, we may incur significant
costs to protect against these interruptions and the threat of security
breaches or to alleviate problems caused by such interruptions or breaches, and
we expect to expend significant financial resources in the future to equip our
new and existing data centers with state-of-the-art security measures. If a
third party were able to misappropriate a consumer's personal or proprietary
information, including credit card information, during the use of an
application solution provided by us, we could be subject to claims, litigation
or other potential liability.

We may become subject to burdensome government regulation and legal
uncertainties that could substantially impair the growth of our business or
expose us to unanticipated liabilities

    It is likely that laws and regulations directly applicable to the Internet
or to Internet application service providers may be adopted. These laws may
cover a variety of issues, including user privacy and the pricing,
characteristics and quality of products and services. The adoption or
modification of laws or regulations relating to commerce over the Internet
could substantially impair the growth of our business or expose us to
unanticipated liabilities. Moreover, the applicability of existing laws to the
Internet and Internet application service providers is uncertain. These
existing laws could expose us to substantial liability if they are found to be
applicable to our business. For example, we provide services over the Internet
in many states in the United States and in the United Kingdom, and we
facilitate the activities of our customers in these jurisdictions. As a result,
we may be required to qualify to do business, be subject to taxation or be
subject to other laws and regulations in these jurisdictions, even if we do not
have a physical presence, employees or property there.

We may be subject to legal claims in connection with the information
disseminated through our network which could have the effect of diverting
management's attention and require us to expend significant financial resources

    As an Internet application service provider, we may face potential direct
and indirect liability for claims of defamation, negligence, copyright, patent
or trademark infringement, violation of securities laws and other claims based
on the nature and content of the materials disseminated through our network.
For example, lawsuits may be brought against us claiming that content
distributed by some of our current or future customers may be regulated or
banned. In these and other instances, we may be required to engage in
protracted and expensive litigation which could have the effect of diverting
management's attention and require us to expend significant financial
resources. Our general liability insurance may not necessarily cover any of
these claims or may not be adequate to protect us against all liability that
may be imposed.

    In addition, on a limited number of occasions in the past, businesses,
organizations and individuals have sent unsolicited commercial e-mails from
servers hosted at our facilities to massive numbers of people, typically to
advertise products or services. This practice, known as "spamming," can lead to
complaints against service providers that enable such activities, particularly
where recipients view the materials received as offensive. We have in the past
received, and may in the future receive, letters from recipients of information
transmitted by our customers objecting to such transmission. Although we
prohibit our customers by contract from spamming, we cannot assure you that our
customers will not engage in this practice, which could subject us to claims
for damages.

                        Risks Related to this Offering

There is no prior public market for our common stock, and you may not be able
to resell shares of our common stock for a profit

    Prior to this offering, there has been no public market for our common
stock. We, together with the underwriters, will determine the initial public
offering price, and this price may not be the price at which the common stock
will trade after this offering. The market price of the common stock may
decline below the initial public offering price. Although the common stock
will be quoted on the Nasdaq National Market, an active trading market may not
develop after this offering. We cannot assure you of the extent to which
investor interest in NaviSite will lead to the development of an active
trading market or how liquid that market may become. A more detailed
discussion of factors to be considered in determining the initial public
offering price is included in this prospectus under the heading
"Underwriting."

The market price of our common stock may experience extreme price and volume
fluctuations

    The market price of the common stock may fluctuate substantially due to a
variety of factors, including:

  .   any actual or anticipated fluctuations in our financial condition and
      operating results;

  .   public announcements concerning us or our competitors, or the Internet
      industry;

  .   the introduction or market acceptance of new service offerings by us
      or our competitors;

  .   changes in industry research analysts' earnings estimates;

  .   changes in accounting principles;

  .   sales of our common stock by existing stockholders; and

  .   the loss of any of our key personnel.

    In addition, the stock market has experienced extreme price and volume
fluctuations. The market prices of the securities of technology and Internet-
related companies have been especially volatile. This volatility has often
been unrelated to the operating performance of particular companies. In the
past, securities class action litigation has often been brought against
companies that experience volatility in the market price of their securities.
Whether or not meritorious, litigation brought against us could result in
substantial costs and a diversion of management's attention and resources.

If our existing stockholders sell a substantial number of shares of our common
stock in the public market, the market price of our common stock will likely
fall

    If our stockholders sell substantial amounts of our common stock in the
public market following this offering, including shares issuable upon the
exercise of outstanding options, the market price of our common stock will
likely fall. CMGI, Dell and Microsoft will directly own approximately 72.1%,
4.0% and 3.6%, respectively, of the outstanding shares of our common stock
upon completion of this offering and will have registration rights which will
permit them to sell all of these shares in the public market approximately 180
days after completion of this offering. These sales also might make it more
difficult for us to sell equity securities in the future at a time and price
that we deem appropriate. After this offering, we will have outstanding
27,430,413 shares of common stock. Of these shares, the 5,500,000 shares being
offered in this offering will be freely tradeable. Our directors, executive
officers and substantially all of our other stockholders have agreed that they
will not sell, directly or indirectly, any common stock without the prior
written consent of BancBoston Robertson Stephens Inc. for a period of 180 days
after the completion of this offering. However, BancBoston Robertson Stephens
Inc. may, in its sole discretion and at any time or from time to time, without
notice, release all or any portion of the securities subject to the lock-up
agreements. Additional information regarding the market for our common stock
is included in this prospectus under the headings "Shares Eligible for Future
Sale" and "Underwriting."

                                      16

We may spend a substantial portion of the net proceeds of this offering in ways
with which you may not agree

    We plan to use the net proceeds of this offering for investment in the
growth of our business, including enhancement and expansion of our network
infrastructure, expansion of our sales and marketing efforts, including the
hiring of additional personnel, enhancement of our application management and
technical expertise and possible acquisitions of complementary businesses and
technologies, and for working capital and general corporate purposes. Our
management will have broad discretion to allocate the net proceeds from this
offering. As a result, investors in this offering will be relying upon
management's judgment with only limited information about its specific
intentions regarding the use of proceeds. We cannot assure you that the
proceeds will be invested to yield a favorable return. Additional information
regarding the ways in which we intend to spend the proceeds of this offering is
included in this prospectus under the heading "Use of Proceeds."

Investors in this offering will experience immediate and substantial dilution
of their investment

    The initial public offering price is expected to be substantially higher
than the book value per share of the outstanding common stock. You will
therefore incur immediate and substantial dilution in the amount of $8.19 per
share based upon an assumed initial public offering price of $11.00 per share.
In addition, to the extent outstanding stock options are exercised, you will
incur further dilution. Additional information regarding the dilution to
investors in our initial public offering is included in this prospectus under
the heading "Dilution."

                           FORWARD-LOOKING STATEMENTS

    This prospectus contains forward-looking statements which involve risks and
uncertainties. These forward-looking statements are often accompanied by words
such as "believes," "anticipates," "plans," "expects" and similar expressions.
These statements include, without limitation, statements about the market
opportunity for Web site and Internet application hosting and management
services, our business strategy, competition and expected expense levels. Our
actual results could differ materially from those expressed or implied by these
forward-looking statements as a result of various factors, including the risk
factors described above and elsewhere in this prospectus.

<PAGE>

                                USE OF PROCEEDS

    We expect to receive net proceeds from the sale of the 5,500,000 shares of
common stock offered by us of approximately $54.7 million, or $63.1 million if
the over-allotment option granted to the underwriters is exercised in full,
based on an assumed initial public offering price of $11.00 per share, and
after deducting underwriting discounts and commissions and estimated offering
expenses payable by us.

    The principal purposes of this offering are:

  .   to increase our equity capital;

  .   to facilitate future access by us to public equity markets;

  .   to provide increased visibility and credibility in the marketplace;
      and

  .   to enhance our ability to use common stock as consideration for
      acquisitions and as a means of attracting and retaining key employees.

    We currently intend to use the net proceeds of this offering for the
following:

  .   enhancement and expansion of our network infrastructure;

  .   expansion of our sales and marketing efforts, including the hiring of
      additional personnel;

  .   enhancement of our application management and technical expertise; and

  .   working capital and general corporate purposes.

    In addition, we may also use a portion of the net proceeds of this offering
for the acquisition of businesses or technologies that are complementary to
those we currently possess. While we evaluate these types of opportunities from
time to time, there are currently no agreements with respect to any specific
acquisitions.

    We have not yet determined the actual expected expenditures and therefore
cannot estimate the amounts to be used for each purpose set forth above. The
amounts and timing of these expenditures will vary significantly depending upon
a number of factors, including, but not limited to, the availability of
construction financing, the success and timing of our hiring efforts, the
amount of cash generated by our operations and the market response to our Web
site and Internet application hosting and management services. Accordingly, our
management will retain broad discretion as to the allocation of the proceeds of
this offering.

    Pending use of the net proceeds as described above, we intend to invest the
net proceeds of this offering in short-term, interest-bearing, investment-grade
securities.

                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our common stock, and
we do not currently intend to pay any cash dividends on the common stock in the
foreseeable future. We expect to retain future earnings, if any, to fund the
development and growth of our business. Future dividends, if any, will be
determined by our board of directors. As a result of not collecting a dividend,
there is a risk that stockholders will not experience a positive return on
their investment unless they sell their shares of common stock at a profit.

                                 CAPITALIZATION

    The following table is a summary of our balance sheet at July 31, 1999:

  .  on an actual basis;

  .  on a pro forma basis after giving effect to the conversion of all
     shares of convertible preferred stock outstanding as of July 31, 1999

     additional shares of common stock upon the conversion of outstanding
     Series B convertible preferred stock issued to CMGI subsequent to July
     31, 1999 and to reflect the sale of 5,500,000 shares of common stock at
     an assumed initial public offering price of $11.00 per share, after
     deducting underwriting discounts and commissions and estimated offering
     expenses payable by us.

                                    DILUTION

    Our pro forma net tangible book value as of July 31, 1999 was $22,574,874,
or $1.03 per share of common stock, as adjusted to reflect the issuance to CMGI
of an aggregate of 1,114,240 additional shares of common stock upon the
conversion of outstanding Series B convertible preferred stock issued to CMGI
subsequent to July 31, 1999. Pro forma net tangible book value per share, as
adjusted to reflect the issuance of the additional CMGI shares, represents the
amount of our total tangible assets less total liabilities, divided by
21,930,413, the pro forma number of shares of common stock outstanding as of
July 31, 1999, as adjusted to reflect the issuance of the additional CMGI
shares. Pro forma net tangible book value dilution per share represents the
difference between the amount per share paid by new investors purchasing shares
of common stock in this offering and the pro forma net tangible book value per
share of common stock immediately after completion of this offering on a pro
forma basis, as adjusted to reflect the issuance of the additional CMGI shares
and the shares issued to new investors. After giving effect to the conversion
of all outstanding shares of convertible preferred stock into an aggregate of
21,861,075 shares of common stock upon completion of this offering and the sale
of the 5,500,000 shares of common stock offered by us at an assumed initial
public offering price of $11.00 per share of common stock, and after deducting
underwriting discounts and commissions and estimated offering expenses payable
by us, our pro forma net tangible book value as of July 31, 1999 would have
been $77,179,874, or $2.81 per share of common stock. This represents an
immediate increase in net tangible book value of $1.78 per share of common
stock to existing stockholders and an immediate dilution in pro forma net

purchasing shares of common stock in this offering. The following table

reserved for issuance upon exercise of outstanding options with a weighted
average exercise price of $2.49 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 contains forward-looking statements that involve
risks and uncertainties. Our actual results could differ materially from those
discussed in the forward-looking statements as a result of a number of factors,
including those set forth in the section of this prospectus under the heading
"Risk Factors" and elsewhere in this prospectus. The following information
should be read in conjunction with the "Selected Consolidated Financial Data"
and our consolidated financial statements and the accompanying notes, each of
which appears elsewhere in this prospectus.

Overview

    We provide enhanced, integrated hosting and management services for
business Web sites and Internet applications. We also provide application
rentals to customers and developers and supply related consulting services. Our
Internet application service offerings allow businesses to outsource the
deployment, configuration, hosting, management and support of their Web sites
and Internet applications in a cost-effective and rapid manner. Our focus on
enhanced management services, beyond basic co-location services, allows us to
meet the expanding needs of businesses as their Web sites and Internet
applications become more complex. The cost for our services varies from
customer to customer based on the number of hosted or managed servers and the
nature and level of services provided.

    We were incorporated in Delaware in December 1998 as a wholly owned
subsidiary of NaviSite Internet Services Corporation as part of a corporate
reorganization of NaviSite Internet Services Corporation. At that time, we
received a contribution of assets from NaviSite Internet Services Corporation
in exchange for 60,589 shares of our common stock and 1,323,953 shares of our
Series A convertible preferred stock. At the same time, NaviSite Internet
Services Corporation contributed the remainder of its assets to NaviNet, Inc.,
another newly formed subsidiary of NaviSite Internet Services Corporation.
Effective as of October 1, 1999, NaviSite Internet Services Corporation was
merged with and into CMGI, leaving NaviSite and NaviNet, Inc. as direct
subsidiaries of CMGI.

    Our predecessor, NaviSite Internet Services Corporation, was incorporated
in Delaware in February 1997 under the name CMG Information Technology, Inc.
and changed its name to NaviSite Internet Services Corporation in May 1997. We
commenced operations in July 1996, funded by CMGI, to support the networks and
host the Web sites of CMGI and a number of CMGI affiliates. CMGI affiliates
include all entities in which CMGI holds an equity interest. We began providing
Web site hosting and Internet application management services to companies
unaffiliated with CMGI in the Fall of 1997.

    All financial information presented here refers only to NaviSite, including
the hosting and Internet application management segments of NaviSite Internet
Services Corporation, and does not include the financial condition or results
of operations of NaviNet, Inc., including the dial-up operations of NaviSite
Internet Services Corporation.

    In July 1998, we acquired Servercast Communications, L.L.C., a Delaware
limited liability company and developer and integrator of Internet
applications, for $1.0 million in notes, plus bridge notes receivable of
$25,000 and $20,000 in acquisition costs. We acquired Servercast principally
for its expertise in online advertising, e-commerce, content management and
streaming media. The purchase price plus associated costs of the acquisition
were recorded as goodwill and are being amortized on a straight-line basis over
five years.

    We intend to expand domestically and internationally and currently have two
new data centers under construction. In addition, we recently converted 3,200
square feet of office space at our current data center location in Andover,
Massachusetts into data center space. In May 1999, we executed a 12-year lease
for a new 150,000 square foot facility located in Andover, Massachusetts,
currently being constructed to our

                                       23
<PAGE>


specifications, which will include a new data center. We anticipate that work
will be completed on the new Massachusetts facility in the Spring of 2000.
Construction also has started on a new 66,000 square foot facility located in
San Jose, California, which will include a new data center. In May 1999, we
executed a seven-year lease for this facility, which should be available for
occupation in the Fall of 1999. We currently are finalizing the terms of
construction contracts for the new Massachusetts facility and the new
California facility. Additional information on these construction contracts is
included in this prospectus under the heading "Certain Transactions--
Relationship and Transactions Between NaviSite and CMGI, Inc.--Leases,
Construction Contracts and CMGI Guarantees." The procurement, development and
equipping of these facilities will significantly increase our costs and
operating expenses.

    Our corporate headquarters are currently shared with CMGI and several other
CMGI affiliates. CMGI allocates rent, facility maintenance and service costs
among these affiliates based upon headcount within each affiliate and within
each department of each affiliate. Services provided by CMGI include support
for enterprise services, rent and facilities, human resources and benefits and
Internet marketing and business development. Actual expenses could have varied
had we been operating on a stand-alone basis. Costs are allocated to us on the
basis of the fair market value for the facilities used and the services
provided. We intend to relocate our executive offices to our new facility, also
located in Andover, Massachusetts, upon completion of that facility, and upon
that relocation, we will no longer share space with CMGI.

    We derive our revenue from a variety of services, including: Web site and
Internet application hosting, which includes access to our state-of-the-art
data centers, bandwidth and basic back-up, storage and monitoring services;
enhanced server management, which includes custom reporting, hardware options,
load balancing and mirroring, system security, advanced back-up options, remote
management and the services of our business solution managers; specialized
application management, which includes management of e-commerce and other
sophisticated applications and their underlying services, including ad-serving,
streaming, databases and transaction processing; and application rentals and
related consulting and other professional services. Revenue also includes
income from the rental of equipment to customers and one-time installation
fees. Revenue is recognized in the period in which the services are performed
and installation fees are recognized in the period of installation. Our
contracts generally are a one-year commitment.

    Our revenue from sales to related parties principally consists of sales of
services to CMGI and other customers that are CMGI affiliates. In general, in
pricing the services provided to CMGI and its affiliates, we have: negotiated
the services and levels of service to be provided; calculated the price of the
services at those service levels based on our then-current, standard prices;
and, in exchange for customer referrals provided to us by CMGI, discounted
these prices by 10%. Additional information about sales of services to CMGI and
its affiliates is included in this prospectus under the heading "Certain
Transactions--Relationship and Transactions between NaviSite and CMGI, Inc.--
Other Transactions with CMGI and its Affiliates." In fiscal 1999, we sold
services to CMGI and 19 CMGI affiliates totaling approximately $7.1 million, or
67% of revenue. Two of these customers accounted for approximately 22% and 16%
of revenue, respectively. As of July 31, 1999, through its ownership of
NaviSite Internet Services Corporation, CMGI owned approximately 89.6% of our
outstanding common stock, with most of the balance owned by Dell Computer
Corporation and Microsoft Corporation.

    Cost of revenue consists primarily of salaries and benefits for operations
personnel, bandwidth fees and related Internet connectivity charges, equipment
costs and related depreciation and costs to run our two data centers, such as
rent and utilities. We expect these costs to increase in dollar terms, but
decline on a percentage of revenue basis, with the growth of our overall
business. We also expect to achieve economies of scale as a result of spreading
more volume over fixed assets, increasing productivity and using new
technological tools.

    Selling and marketing expenses consist primarily of salaries and related
benefits, commissions and marketing expenses such as advertising, product
literature, trade shows, marketing and direct mail programs. We expect selling
and marketing expenses to increase significantly in dollar terms, but decline
on a percentage

                                       24
<PAGE>

of revenue basis, as we continue to invest in these areas to promote brand
recognition and to acquire new customers. We intend to accomplish this by
hiring additional sales and marketing personnel, opening additional sales
offices and increasing spending on public relations, advertising and marketing
programs.

    General and administrative expenses include the costs of financial, leasing
and administrative personnel, professional services and corporate overhead.
Also included are intercompany charges from CMGI for facilities, human resource
support and business development. We expect the dollar value of these expenses
to increase in future periods, but decline on a percentage of revenue basis, as
we hire additional personnel and incur additional costs related to the growth
of our business and our operations as a public company.

    Product development expenses consist mainly of salaries and related costs.
Our product development staff focuses on Internet applications and network
architecture. This group identifies new Internet application software
offerings, incorporates these new offerings into our suite of service offerings
and positions these new offerings for marketing, sale and deployment. Our
product development group also identifies, selects and implements the various
technologies, including network storage and back-up, that provide the basic
infrastructure for both our internal network and the solutions we offer our
customers. As with sales and marketing, we believe that increased investment in
product development is critical to attaining our strategic objectives and
maintaining our competitive edge. We expect the dollar value of product
development expenses to increase significantly in future periods, but decline
on a percentage of revenue basis.

    We have incurred significant net losses and negative cash flows from
operations since our inception and, as of July 31, 1999, had an accumulated
deficit of approximately $34.7 million. These losses primarily have been funded
by CMGI through the issuance of convertible preferred stock and convertible
debt and by equipment lease financing. We intend to continue to invest heavily
in sales, marketing, promotion, technology and infrastructure development as we
grow. As a result, we believe that we will continue to incur operating losses
and negative cash flows from operations for at least the next three years and
that the rate at which such losses will be incurred may increase.

Comparison of Fiscal Years Ended July 31, 1999 and 1998

 Revenue

    Total revenue increased 161% to approximately $10.5 million in fiscal 1999,
from approximately $4.0 million in fiscal 1998. The increase in revenue is due
to additional business with CMGI and CMGI affiliates and the increase in the
number of non-affiliated customers to 106 as of July 31, 1999 from 37 as of
July 31, 1998 (including customers of Servercast, acquired by us on July 1,
1998). Customers of Servercast accounted for $1,143,000, or 11%, of total
revenue in fiscal 1999.

 Cost of Revenue

    Cost of revenue increased 129% to approximately $20.3 million in fiscal
1999, from approximately $8.9 million in fiscal 1998. As a percentage of
revenue, cost of revenue decreased to 193% in fiscal 1999, from 220% in fiscal
1998. The dollar-value increase in each period is due primarily to the costs
associated with increased investment in our existing data centers. These costs
principally include labor and headcount expenses, additional equipment and
maintenance costs and increased bandwidth and connectivity charges.

 Operating Expenses

    Selling and Marketing. Selling and marketing expenses increased 172% to
approximately $6.9 million in fiscal 1999, from approximately $2.5 million in
fiscal 1998. This increase is due primarily to the development of NaviSite's
sales and marketing capability in connection with the commencement of sales to
unaffiliated customers. These costs primarily include salaries and commissions
and expenses for marketing programs, advertising and product literature.

    General and Administrative. General and administrative expenses increased
242% to approximately $4.8 million in fiscal 1999, from approximately $1.4
million in fiscal 1998. The dollar-value increase in general and administrative
expenses is due to both an increase in salaries and related costs, to
approximately $1.7 million in fiscal 1999, from approximately $752,000 in
fiscal 1998, resulting from the hiring of additional administrative and finance
personnel to support our growing operations and an increase in intercompany
charges from CMGI to approximately $494,000 in fiscal 1999, from approximately
$161,000 in fiscal 1998, for human resource support, business development and
corporate overhead. Other expenses contributing to the dollar-value increase
include moving and rental costs associated with the occupation of our current
corporate headquarters and legal and professional fees, which increased to
approximately $1.1 million in fiscal 1999, from approximately $221,000 in
fiscal 1998, associated with: Year 2000 consultants and contract labor; legal
review of operating contracts, leases, option plans and the Navisite Internet
Services Corporation corporate reorganization; and accounting and finance
contract labor. General and administrative expenses associated with Servercast
(acquired by us on July 1, 1998) increased to approximately $517,000 in fiscal
1999, from approximately $19,000 in fiscal 1998.

    Product Development. Product development expenses increased to $2.6 million
in fiscal 1999, from approximately $287,000 in fiscal 1998. This increase is
due primarily to the costs associated with an increase in product development
personnel by July 31, 1999 to 20, from one person at the inception of our
product development operations in 1998. This growth in product development
personnel reflects our increased service offerings and emphasis on application
services.

 Interest Expense, net

    Interest expense, net increased to approximately $347,000 in fiscal 1999,
from $85,000 in fiscal 1998. This increase is due primarily to the inclusion in
interest expense, net in fiscal 1999 of approximately $303,000 of interest on
intercompany debt at a rate of seven percent per annum pursuant to an
arrangement entered into between NaviSite and CMGI in the second half of fiscal
1998. Interest expense associated with the issuance of term notes in connection
with our acquisition, in July 1998, of Servercast totaled approximately $55,000
during fiscal 1999. Interest expense on long-term capital lease obligations is
also included in interest expense, net.

Comparison of Fiscal Years Ended July 31, 1998 and 1997

 Revenue

    Total revenue increased 20% to approximately $4.0 million in fiscal 1998,
from approximately $3.4 million in fiscal 1997. Because NaviSite first sold its
services to unaffiliated customers in the Fall of 1997, almost all of
NaviSite's revenue in fiscal 1998 and fiscal 1997 came from CMGI and CMGI
affiliates. The dollar-value increase in revenue in fiscal 1998 from fiscal
1997 is due to a growth in revenue of approximately $510,000 from services
provided to affiliated customers and the addition of commercial customers with
revenue totaling $158,000. In fiscal 1998, three customers, all affiliates of
CMGI, accounted for 40%, 19% and 11% of revenue, respectively. In fiscal 1997,
these same three customers accounted for 46%, 28% and 14% of revenue,
respectively.

 Cost of Revenue

    Cost of revenue increased 154% to approximately $8.9 million in fiscal
1998, from approximately $3.5 million in fiscal 1997. As a percentage of
revenue, cost of revenue increased to 220%, from 104%, reflecting costs
associated with the build-out of the Andover data center and the opening of the
Scotts Valley data center in anticipation of future growth.

 Operating Expenses

    Selling and Marketing. Selling and marketing expenses increased to $2.5
million in fiscal 1998, from $347,000 in fiscal 1997. The increases are the
result of significant growth in our sales force and marketing group during this
period as we commenced sales to unaffiliated customers. Advertising costs and
significant initial costs for product literature also are components of the
increase in fiscal 1998 over fiscal 1997.

    General and Administrative. General and administrative expenses increased
202% to approximately $1.4 million in fiscal 1998, from approximately $467,000
in fiscal 1997. These increases are the result of increased payroll and related
costs and professional fees required to support our growing operations.

    Product Development. Product development expenses increased to $287,000 in
fiscal 1998 due to initial hiring in our product development group at its
inception in fiscal 1998. Product development expenses were zero in fiscal
1997. The introduction of product development personnel reflects our increased
service offerings and emphasis on application services.

    Interest expense, net increased to $85,000 in fiscal 1998, from $1,000 in
fiscal 1997. The increase in fiscal 1998 from fiscal 1997 is due primarily to
the inclusion in interest expense, net in fiscal 1998 of approximately $65,000
of interest on intercompany debt at a rate of seven percent per annum pursuant
to an arrangement entered into between NaviSite and CMGI in the second half of
fiscal 1998. Interest expense on long-term capital lease obligations is also
included in interest expense, net in fiscal 1998 and is the sole component of
interest expense, net in fiscal 1997.

Income Taxes

    NaviSite is part of the CMGI consolidated group for tax purposes, and as
such, all benefits of federal tax losses from inception through July 31, 1999
have been used to the benefit of CMGI in its consolidated return. As a result,
NaviSite has no tax loss carryforwards or carrybacks as of July 31, 1999.

Liquidity and Capital Resources

    Since our inception, our operations have been funded primarily by CMGI
through the issuance of preferred stock and convertible debt.

    Net cash used in operating activities amounted to $20.2 million, $7.9
million and $644,000 for fiscal 1999, fiscal 1998 and fiscal 1997,
respectively. The increase in cash used in operations has primarily been caused
by increasing net operating losses, which are partially offset by non-cash
depreciation and amortization charges included in the applicable net loss and
increases in accounts payable and accrued expenses.

    Net cash used in investing activities amounted to $9.8 million, $1.2
million and $1.6 million during fiscal 1999, fiscal 1998 and fiscal 1997,
respectively. The net cash used for investing activities was utilized to
acquire property and equipment required to support the growth of the business
and to expand data center infrastructure.

    Net cash provided by financing activities amounted to $33.3 million, $9.1
million and $2.2 million for fiscal 1999, fiscal 1998 and fiscal 1997,
respectively. Cash provided for financing activities included funds advanced
from CMGI, totaling $19.0 million, to fund our operations in 1999. In addition,
cash provided by financing activities in fiscal 1999 included $8.0 million in
net proceeds from the issuance of Series C convertible preferred stock to Dell
Computer Corporation and $7.2 million in net proceeds from the issuance of
Series D convertible preferred stock to Microsoft Corporation. Cash provided by
financing activities in fiscal 1998 and fiscal 1997 primarily was related to
funds advanced from CMGI to fund our operations. Our current interest rate for
our financing activities through CMGI is seven percent. Non-cash financing
transactions included capital lease financing for equipment and a software
vendor payable in fiscal 1999 and fiscal 1998.

    CMGI has historically funded our operations as needed, increasing our
obligations to CMGI and allowing us to maintain a zero-balance cash account.
Customer and other receipts have been remitted to CMGI and have been applied to
reduce our obligations to CMGI. We have issued a secured convertible demand
note to CMGI in exchange for the cancellation of all outstanding intercompany
debt incurred by us to CMGI prior to April 30, 1999. This note also provides
for additional advances by CMGI to us after April 30, 1999. CMGI may elect to
convert amounts payable under the note into Series B convertible preferred
stock at any time. Additional intercompany debt accrues at a rate of seven
percent per year, compounded monthly until the day CMGI elects to convert the
debt into shares of Series B convertible preferred stock. The amount of each
borrowing represented by the note is convertible from time to time into the
number of shares of Series B convertible preferred stock equal to one-tenth of
the quotient of the aggregate amount of principal and interest to be so
converted, divided by the applicable conversion price for that fiscal quarter.

    The conversion price applicable to advances made in any fiscal quarter,
except advances made in the fiscal quarter during which a qualified initial
public offering occurs and advances converted into Series B convertible
preferred stock in the same fiscal quarter in which they were made, is
determined by dividing our total enterprise value as of the fiscal quarter end
(as determined in good faith by our board of directors) by the number of shares
of common stock outstanding on a fully diluted, as-if-converted basis. Our
total enterprise value, and the conversion price applicable to advances made
under the note, has increased significantly since the fiscal quarter ended
January 31, 1999. For the fiscal quarter ended January 31, 1999, our enterprise
value was based on a discounted cash flow analysis. Our enterprise value for
the fiscal quarter ended April 30, 1999, however, was determined through arms'
length negotiations with, and subsequent sales of our Series C convertible
preferred stock and Series D convertible preferred stock to, two unaffiliated
third parties-Dell and Microsoft. While our business experienced certain
positive operating results during our fiscal quarter ended April 30, 1999,
including principally growth in our revenue from customers unaffiliated with
CMGI and growth in the total number of our customers and in our customers
unaffiliated with CMGI, we believe that the significant increase in our total
enterprise value for our fiscal quarter ended April 30, 1999 from that for our
fiscal quarter ended January 31, 1999 results primarily from the fact that our
total enterprise value for our fiscal quarter ended April 30, 1999 was
determined through arms' length negotiations with our two third-party
investors. The conversion prices for the Series B convertible preferred stock
issued upon conversion of advances made under the note in the fiscal quarter
ended April 30, 1999, the Series C convertible preferred stock and the Series D
preferred stock all are based on our enterprise value for the fiscal quarter
ended April 30, 1999.

                                       29

    Under this note, intercompany debt in the aggregate amount of approximately
$10,761,000, representing $5,348,000 advanced during the quarter ended January
31, 1999 and an additional $5,413,000 advanced during the quarter ended April
30, 1999, in each case including interest accrued during the applicable fiscal
quarter, was converted into 490,332 shares of Series B convertible preferred
stock (based upon applicable conversion prices of $12.74 and $76.68,
respectively). Effective June 4, 1999, CMGI elected to convert intercompany
debt in the aggregate amount of approximately $3,952,000, representing funds
advanced subsequent to the quarter ended April 30, 1999, into 51,527 shares of
Series B convertible preferred stock (based upon a conversion price of $76.68).
Under the terms of the note, because CMGI elected to convert these advances
prior to the end of the fiscal quarter in which the advances were made, the
applicable conversion price was the conversion price in effect for the
immediately preceding fiscal quarter. Immediately prior to the completion of
this offering, CMGI will convert intercompany debt in the aggregate amount of
approximately $12,257,000, representing funds advanced subsequent to the
quarter ended July 31, 1999, into 111,424 shares of Series B convertible
preferred stock (based upon a conversion price of $110, assuming an initial
public offering price of $11.00 per share). Upon completion of this offering,
each issued and outstanding share of Series B convertible preferred stock will
convert into ten shares of common stock, or 6,532,830 shares of common stock in
the aggregate. We do not expect to borrow funds from CMGI after completion of
this offering.

    In connection with the construction contract for our new Andover,
Massachusetts facility, we will be required to obtain a letter of credit in the
amount of the remaining balance due under the contract, which is currently
estimated to be less than $15 million. See "Certain Transactions--Relationship
and Transactions between NaviSite and CMGI, Inc.--Leases, Construction
Contracts and CMGI Guarantees." We expect to commence negotiations on the terms
of the letter of credit prior to the completion of this offering.

    We have experienced a substantial increase in our expenditures since
inception consistent with our growth in operations and staffing. We anticipate
that expenditures will continue to increase for at least three years as we
accelerate the growth of our business. Additionally, we will continue to
evaluate investment opportunities in businesses that management believes will
complement our technologies and market strategies.

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

Quantitative and Qualitative Disclosure About Market Risk

    We are exposed to market risk related to changes in interest rates. We
intend to invest excess cash balances in cash equivalents. We believe that the
effect, if any, of reasonably possible near-term changes in interest rates on
our financial position, results of operations and cash flows will not be
material.

Year 2000 Considerations

    Currently, many installed computer systems and software products are coded
to accept only two-digit entries in the date code field. Beginning in the year
2000, 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 continue to function properly into the

                                       30
<PAGE>

Year 2000 and beyond. We recognize the need to assure that our operations will
not be adversely impacted by Year 2000 software and computer system failures.
We confront the Year 2000 problem in several contexts:

    Our Facilities and Services. We are a hosting and application management
services provider and we rely on our network infrastructure, software and
hardware to provide our services. Because we offer computer-related services
and because of the business-critical nature of many of our customers'
applications, our risk of lawsuits related to Year 2000 issues is likely to be
greater than that of companies in some other industries. We currently have 13
full-time employees and consultants dedicated to completing our internal Year
2000 project plan. As of July 31, 1999, we have spent nearly $950,000 on our
Year 2000 compliance effort and we have budgeted up to an additional $650,000
to complete our internal Year 2000 project plan.

    Our Year 2000 project plan consists of five phases:

  .  awareness, which consists of informing our employees, customers and
     suppliers (orally and in writing) of the need to remediate computer
     systems and software products relating to our operations;

  .  inventory, which is comprised of our efforts to identify and record the
     computer systems and software products involved in the provision of our
     service offerings and elsewhere in our operations;

  .  assessment, which is the process of isolating Year 2000 issues with the
     systems and products identified in the inventory phase of our Year 2000
     project plan and identifying necessary upgrades and replacements to
     address these Year 2000 issues;

  .  remediation, which consists of implementing the necessary upgrades and
     replacements identified in the assessment phase of our Year 2000
     project plan; and

  .  contingency planning, which involves both the proactive visioning of
     failures of computer systems and software products and of other adverse
     impacts on our operations caused by the failure or inadequate
     completion of one or more of the first four phases of our Year 2000
     project plan and the suggestion and documentation of reasonable
     solutions to resolve these potential failures.

We have substantially completed the awareness, inventory and assessment phases
of our Year 2000 project plan. We also continue to conduct awareness campaigns
as needed, update our inventory and conduct Year 2000 assessment on an ongoing
basis as new computer systems and software products are introduced to our data
centers or integrated into our operations. We intend to continue this ongoing
inventory and assessment process through at least December 31, 2000. The
awareness, inventory and assessment phases of our Year 2000 project plan
revealed to us a number of potential problems at the operating system and BIOS
levels with: hosted servers owned by both us and our customers; networked and
standalone desktop computers; and our network operations centers. In addition,
these phases of our plan revealed potential problems with hardware devices
utilized as part of our network infrastructure, including, for example,
routers. All of the revealed problems are ordinary and routine in nature, and
all are able to be remedied with standard software or hardware patches. In most
cases, if time permits, we test vendor software patches for Year 2000
compliance.

  We anticipate completing the remediation and contingency planning phases by
December 1, 1999. The remediation phase of our Year 2000 project plan is
designed to remediate Year 2000 problems at the operating system and BIOS
levels as to computer systems used by customers for whom we provide management
services. A number of managed servers remain on our inventory for remediation.
The remediation of certain of these servers has been delayed as a result of
customer requests to postpone scheduled remediation based on the internal
business needs of those customers. We believe that remediation will continue
through December 1, 1999 because of these delays with customer server
remediation and the potential release by suppliers of new patches. As new
managed servers are brought on line through at least December 31, 1999, we will
certify Year 2000 compliance before these servers are installed. As described
in further detail below, our co-location customers have full responsibility for
remediating their own servers and applications, and all of our customers are
responsible for remediating their own application software and any desktop
computers used by them in connection with the services we provide. Year 2000
problems isolated to date with respect to our desktop computers, network
operations centers and network infrastructure have been substantially
remediated.

                                       31
<PAGE>

    The formal contingency planning phase of our Year 2000 project plan is
complete. We anticipate continuing to update our contingency plans as required,
at least through the end of the remediation phase of our Year 2000 project
plan.

    Because our infrastructure incorporates components from different
providers, we may be unable to determine whether any of these components will
cause unexpected Year 2000 problems or whether different components will
interact in a way that causes malfunctions. While we expect that our network
infrastructure and all other material components of our facilities will not
experience any Year 2000-related failures, we cannot assure you that we will
not experience these failures or that we will not discover any compliance
problems in the future. Our failure timely and adequately to address Year 2000
compliance issues in our business could result in lost revenues and claims of
mismanagement, misrepresentation or breach of contract and related litigation,
which could be costly and time-consuming for us to defend.

    Our Customers. We also face risks from customer-provided computer systems
and application software that we host in our data centers that in many cases
has been customized by outside service providers or customer personnel. While
we inform our co-location customers that they are responsible for the Year 2000
compliance of their hosted computer systems and all customers that they are
responsible for the Year 2000 compliance of their own application software, we
cannot assure you that our customers will take the steps necessary to achieve
Year 2000 compliance. The failure of customers and third-party providers to
ensure that their hosted computer systems and application software is Year 2000
compliant could disrupt our operations, resulting in lost revenue and increased
operating costs. In addition, our customers maintain their internal operations
on networks which may be impacted by Year 2000 complications, which could in
turn affect our internal structure or our ability to provide services to them.
We cannot assure you that our customers will upgrade their internal networks or
otherwise provide appropriate remediation for Year 2000 compliance. In
addition, in the event that a significant number of our customers experience
Year 2000-related problems, whether due to our products or not, demand for
technical support and assistance may increase dramatically. In this case, our
costs for providing technical support may rise and the quality of our service
or our ability to manage incoming requests may be impaired.

    Our Suppliers. In addition, we depend on software and hardware supplied by
numerous vendors to provide our application hosting and management services,
rental services and consulting services. We are currently seeking assurances
from our existing vendors that their products are Year 2000 compliant, and we
require that all new software application providers certify that they are Year
2000 compliant before we enter into agreements with them. However, because in
most cases we do not independently verify the Year 2000 compliance of vendors'
products, we cannot assure you that these vendors' guarantees are true or
sufficient or that we will not encounter Year 2000 compliance problems
involving their products.

    We cannot assure you that we will be able to provide our services and
maintain our operations if we are unable to obtain products, services or
systems that are Year 2000 compliant when we need them. In addition, if vendors
and service providers cannot deliver their products because of their own Year
2000 compliance problems or as a result of systemic failures such as power
outages relating to the Year 2000, we could experience increased operating
costs and lost revenue.

Inflation

    We believe that our revenues and results of operations have not been
significantly impacted by inflation during the past three fiscal years.

Recent Accounting Pronouncements

    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 certain internal costs
related to the implementation of computer software obtained for internal use.
NaviSite 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 issued
Statement of Position 98-5, "Reporting Costs of Start-Up Activities." 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 consolidated financial statements. NaviSite 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
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. NaviSite is required to adopt this standard in the first quarter of
fiscal year 2001 pursuant to SFAS No. 137 (issued in June 1999), which delays
the adoption of SFAS 133 until that time. NaviSite expects that the adoption of
SFAS 133 will not have a material impact on the its financial position or its
results of operations.

                                    BUSINESS

Company Overview

    NaviSite is an Internet application service provider offering Web site and
application hosting and management services. Our Internet application service
offerings allow businesses to outsource the deployment, configuration, hosting,
management and support of their Web sites and Internet applications in a cost-
effective and rapid manner. Our focus on enhanced management services, beyond
basic co-location services, allows us to meet the expanding needs of businesses
as their Web sites and Internet applications become more complex. We also
provide our customers with access to our state-of-the-art data centers and the
benefit of our direct private transit Internet connections to major Internet
backbone providers. We only use direct private transit Internet connections,
which differentiates our network infrastructure from that of most of our
competitors. These connections increase reliability and download speeds.

    The scalability of our infrastructure and cost-effectiveness of our
solutions allow us to offer a comprehensive suite of services to meet the
current and future hosting and management needs of our customers. Our suite of
service offerings includes:

  .   Web site and Internet application hosting, which includes access to
      our state-of-the-art data centers, bandwidth and basic back-up,
      storage and monitoring services;

  .   Enhanced server management, which includes custom reporting, hardware
      options, load balancing and mirroring, system security, advanced back-
      up options, remote management and the services of our business
      solution managers;

  .   Specialized application management, which includes management of e-
      commerce and other sophisticated applications and their underlying
      services, including ad-serving, streaming, databases and transaction
      processing; and

  .   Application rentals and related consulting and other professional
      services.

Industry Background

    Growth of Business Use of the Internet. The dramatic growth in Internet
usage in recent years, combined with enhanced functionality, accessibility and
security, has made the Internet increasingly attractive to businesses as a
medium for communication and commerce. Forrester Research, Inc. has estimated
that the number of U.S. enterprise businesses online will increase from
approximately 1.8 million in 1998 to approximately 4.3 million in 2003.

    As business use of the Internet grows, we believe those businesses which
are utilizing the Internet are seeking to identify and implement increasingly
sophisticated Internet applications. These new applications permit businesses
to:

  .   engage in business-to-business and business-to-consumer e-commerce;

  .   enhance business sales efforts through Web-based technologies such as
      ad-serving and streaming;

  .   build and enhance customer relationships by providing Internet-based
      customer service and technical support; and

  .   communicate and conduct business more rapidly and cost-effectively
      with customers, suppliers and employees worldwide.

    As a result, the proliferation of business Web sites and Internet
applications has created a strong demand for specialized information technology
support and application expertise.

    Movement Toward Outsourcing. A growing number of businesses using the
Internet as part of their business strategy have chosen to outsource Internet
application development, implementation and support, particularly the hosting
and management of their Web sites and Internet applications. This follows an
overall movement toward outsourcing of information technology services.
According to Forrester Research, businesses

                                       34
<PAGE>

in the United States are now spending approximately 25% of their overall
information technology budgets on outsourced services. The growth in outsourced
hosting and management of Web sites and Internet applications is driven by a
number of factors, including:

  .   the desire of businesses to improve the reliability, availability and
      overall performance of their Web sites and Internet applications as
      those applications increase in complexity and importance;

  .   the desire of businesses to reduce time to market;

  .   the challenges faced by businesses in hiring, training and retaining
      application engineers and information technology employees with
      Internet expertise;

  .   the increased costs associated with developing and maintaining
      business networks and software applications; and

  .   deployment risk and the risk of technological obsolescence as they
      attempt to capitalize on leading-edge technologies.

    Forrester Research has estimated that the market for managed Web site
hosting in the United States will grow from less than $1.0 billion in 1998 to
over $14.0 billion in 2003. In January 1998, Forrester Research estimated that
the market for branded application outsourcing services in the United States
will grow to $21.1 billion by 2001.

    Need for Providers of Enhanced, Integrated Hosting and Application
Management Services. Many businesses have outsourced hosting and management of
their Web sites and Internet applications. However, many Web site hosting
providers lack the requisite expertise to implement and manage increasingly
sophisticated Internet applications. Moreover, many of these providers lack the
scalable capacity, high-speed connectivity, monitoring capabilities and level
of reliability and availability which businesses demand. System integrators and
turnkey application developers often have the requisite expertise and resources
to supply businesses with highly customized application solutions, but these
solutions are expensive and time consuming to implement. Some businesses
attempt to reduce cost and shorten time to deployment by utilizing multiple
vendors, each of which provides only a partial solution. This has created
significant opportunity for an application service provider which can offer Web
site and Internet application deployment, configuration, hosting, management
and support.

The NaviSite Solution

    We provide a range of integrated, scalable Web site and Internet
application hosting and management services that can be deployed in a cost-
effective and rapid manner. Our Internet application service offerings allow
customers to outsource the deployment, configuration, hosting, management and
support of Web sites and Internet applications. Our focus on enhanced
management services, beyond basic co-location services, allows us to meet the
expanding needs of businesses as their Web sites and Internet applications
become more complex. Key components of our services include:

    Cost-Effective Application Services. The scalable nature of our
infrastructure, the repeatability of our Internet application services and our
hosting and management expertise allow us to provide our customers with Web
site and Internet application hosting and management services on a cost-
effective basis. We believe that our customers would otherwise be required to
make significant expenditures to replicate our performance, reliability and
expertise either internally or by using outside vendors.

    Rapid Deployment. We offer our customers the ability to rapidly deploy
Internet applications, often in a matter of weeks, instead of months. We
believe that we can deploy sophisticated Internet applications much more
rapidly than businesses can deploy the same applications in-house. Moreover,
our Internet application solutions can be deployed more rapidly than highly
customized applications. This is crucial as our customers develop a Web
presence and need to have their Web sites and Internet applications online as
quickly as possible.

                                       35
<PAGE>

    High-Performance, World-Class Infrastructure. Our infrastructure has been
designed expressly to meet the more demanding technical requirements of
sophisticated Web sites and Internet applications and to provide capacity ahead
of customer demand. We believe that this approach to capacity facilitates the
high-speed data transmission, reliability and availability which our customers'
Web sites and Internet applications demand. In addition, our direct private
transit Internet connections to major Internet backbone providers increase
reliability and download speeds and differentiate our network infrastructure
from that of most of our competitors. Our high-performance infrastructure
together with our trained and experienced staff enable us to offer levels of
service which are backed by guarantees which we believe are among the highest
and most comprehensive in the industry.

Strategy

    NaviSite's objective is to be the leading Internet application service
provider. We plan to achieve this goal by continuing to enhance and leverage
our expertise, service offerings and infrastructure to provide customers with
integrated, reliable and secure Internet-based business solutions. Key
components of our strategy include:

    Expand Our Suite of Internet Applications. We intend to both increase the
number and vary the kind of applications and application management services we
offer and increase revenue from application rentals. We continue to introduce
Internet business applications which enable customers to develop a Web-based
business presence. Currently, we offer our customers e-commerce and other
sophisticated applications and their underlying services, including ad-serving,
streaming, databases and transaction processing. We focus on application
services which are repeatable, meaning services that we can provide to
customers with minimal additional customization and integration. We believe
that this repeatability decreases our time to market, reduces our operating
risks and produces a higher return on our investment.

    Offer Multiple Service Levels to Meet the Evolving Needs of Customers. We
offer multiple service levels to customers so that we can meet their needs for
Internet application services at each stage in the development of their Web-
based operations. For example, a customer initially may use our Web site or
Internet application hosting services or enhanced server management. Later, as
its operations grow and the Internet becomes more of an integral part of its
business strategy, the customer may use our specialized application management
services or application rentals. We believe we have created a competitive
advantage by offering multiple service levels to meet the evolving needs of
customers.

    Increase Brand Awareness. We intend to increase awareness of the NaviSite
brand in key business markets and associate the NaviSite brand with the highest
quality Web site and Internet application hosting and management services, high
performance, world-class infrastructure and superior customer service. We
believe that this awareness and association is essential to the continued
expansion of our customer base. We plan to aggressively build the NaviSite
brand through our industry relationships and the use of marketing and co-
marketing programs.

    Enhance Our Expertise and Technological Capabilities. We have acquired, and
intend to continue to enhance, the expertise and technological capabilities
required to conduct and grow our business ahead of customer demand. This means
hiring and training application experts before introducing a new application to
customers. This also means expanding existing data centers, adding data
centers, keeping current with key technological trends and increasing
bandwidth. We intend to enhance our expertise by training existing personnel
and by hiring and retaining new application service professionals. We believe
the combination of our Web site and Internet application hosting and management
expertise and our scalable infrastructure provide us with a competitive
advantage.

    Continue to Develop and Leverage Industry Relationships. We believe our
industry relationships with Internet application software vendors and
developers, application and system integrators, hardware suppliers and others
provide us with enhanced market opportunities. Through these relationships, we
purchase, license or

                                       36
<PAGE>

lease services or products to expand our application service offerings or
infrastructure. We also intend to expand our channel sales capability by
working with an increasing number of system integrators and Internet
application software developers and providers. By leveraging our current and
future industry relationships, we intend to not only increase our market
visibility and credibility but also offer our clients more fully integrated
Web site and Internet application hosting and management services.

    Access Foreign Markets. We continually assess the need for foreign
operations based on opportunities in specific geographic locations. We
currently have data center capacity in Europe through a bilateral agreement
for Internet hosting services with Planet Online. This arrangement was
established to meet the overseas demands of existing domestic customers. As
the needs of our existing and prospective customers evolve, we intend to take
advantage of foreign market opportunities as they arise.

    Pursue Strategic Acquisitions. As opportunities arise, we intend to
continue to pursue strategic acquisitions that can provide complementary
capabilities, technical personnel, established customer relationships and
geographic presence in domestic and international markets.

Services

    We offer a comprehensive suite of services to meet the current and future
hosting and management needs of our customers.

    Web Site and Internet Application Hosting. Our Web site and Internet
application hosting services provide customers with access to our state-of-
the-art data centers, bandwidth and basic back-up, storage and monitoring
services. Customers are able to access their servers 24-hours-a-day, seven-
days-a-week. These co-located servers are securely housed in separate,
limited-access rooms in our data centers. In fiscal 1999, approximately 17% of
our revenue was derived from basic co-location customers to which we provide
no enhanced or specialized management services.

    Web Site and Application Management. We provide both enhanced server
management and specialized application management. Both types of management
services permit us to provide customers with comprehensive problem-solving
solutions, from identification to resolution to post-resolution analysis. To
provide these services, our trained technical personnel utilize advanced
network monitoring and management tools for Web site and application
troubleshooting, together with internal policies and procedures designed to
ensure rapid, effective solutions to technical problems.

    Our enhanced server management services include custom reporting, hardware
options, load balancing and mirroring, system security, advanced back-up
options, remote management and the services of our business solution managers.

    We also provide specialized application management services for select
software applications, such as:

  .   ad-serving, which allows customers to conduct advertising and
      profiling over the Internet; and

  .   e-commerce, which enables customers to implement online stores,
      customer ordering, payment and fulfillment.

    Application Rentals. We offer Internet application rentals to customers
and application developers who need to access sophisticated Internet
applications or application components which can be customized by developers
as part of a complete software solution. Often, obtaining a full license for
these applications is too expensive for customers or application developers,
especially for short-term or single-project use. In addition, these
applications may require experienced personnel to deploy and configure them.
Applications which we currently offer to customers on a rental basis include
Engage Technologies, Inc.'s ad-serving application and a number of Oracle
Corporation's database applications. Internet application components that we
offer to application developers include streaming, personalization,
statistical reporting and imaging services.

                                      37
<PAGE>

    Professional Services. We supply consulting and other professional services
to our customers. These services include network and system configuration and
architecture, project implementation, bandwidth planning and, in limited cases,
basic software development and system integration.

Sales and Marketing

    Our sales and marketing objective is to leverage our Web site and Internet
application hosting and management expertise to become the leading provider of
Internet application services. We have developed a sales and marketing strategy
that initially has targeted businesses that have adopted the Internet as an
integral part of their business strategy. We intend to increasingly target more
traditional enterprises as they incorporate the Internet into their business
models.

    Our sales efforts focus on direct sales, as well as channel sales through
various industry relationships. We plan to establish a leading position in our
target markets by aggressively expanding our sales force, continuing to
establish and leverage industry relationships to increase channel sales and
expanding our marketing staff.

    Direct Sales. Our direct sales professionals include:

  .   sales representatives, who conduct sales campaigns, identify targeted
      prospects, oversee sales territories and manage customer
      relationships;

  .   sales engineers, who discuss with prospective customers their Web site
      and Internet application hosting and management needs and technical
      requirements; and

  .   telesales representatives, who qualify customer leads.

    Our direct sales teams currently are located in: Andover, Massachusetts;
New York, New York; and San Jose and Los Angeles, California. We plan to expand
our sales force to provide geographic presence in other key markets.

    Channel Sales. We have developed important industry relationships to
enhance our channel sales and marketing capabilities. In 1998, we began
pursuing channel sales relationships through our Alliance Partner Program. We
also have generated leads or referrals on an informal basis from application
and system integrators and Internet application software vendors. We intend to
continue to leverage our industry relationships to develop customer referrals,
mutual referral relationships, enhanced service offerings, and in some cases,
co-selling and cross-selling opportunities. Although our industry relationships
have not yet matured into significant sources of new customers, we expect these
relationships to generate more referrals and leads in the future.

    Marketing. Our marketing group is responsible for corporate and product
marketing, product management, corporate communications, public relations, lead
generation and marketing communications. As with our sales approach, our
overall marketing strategy focuses on supporting both direct sales and channel
sales. The key goals for our current marketing efforts are to establish a
national and local awareness of the NaviSite brand and our services, position
ourselves as a leading Web site and Internet application hosting and management
partner, develop and enhance channel sales relationships and demonstrate to
potential customers how our services differentiate us from our competition. Our
marketing efforts include:

  .   comprehensive lead generation through telemarketing, direct marketing,
      direct mail programs, electronic and print advertising, seminars and
      targeted shows and events;

  .   interactive, online marketing programs;

  .   marketing communications and public relations materials to sustain
      press coverage in both trade and business publications;

  .   market development activities targeted to Web site design firms,
      Internet application developers and consultants;

                                       38
<PAGE>

  .   lead generation, referrals, mutual Web site links or co-marketing
      through industry relationships with technology vendors such as Cisco
      Systems Inc., Oracle Corporation, BMC Software Distribution, Inc., EMC
      Corporation and ArrowPoint Communications, Inc.; and

  .   strategic marketing relationships with Dell and Microsoft, which are
      principal stockholders of NaviSite.

    We expect to make significant investments in these and other marketing
programs to increase awareness of the NaviSite brand. We also intend to
continue to leverage our advantageous relationship with CMGI as a source of
lead generation and referrals for our services.

 Industry Relationships

    In our sales and marketing efforts, we are pursuing industry relationships
targeted by our Alliance Partner Program.

    Web and Application Developers. We have developed relationships with
multiple small- to medium-sized Web site design firms, Internet application
developers, consultants and other similar companies that have established
relationships with our target customers. These companies generally lack the
infrastructure and expertise needed to offer their customers a complete, cost-
effective solution and, as a result, turn to us to provide hosting and
management services and expertise to enhance their own product and service
offerings. These relationships provide us with greater market reach through
referrals, without the related overhead costs. In return, we offer these
companies discounts on our services, participation in networking events and
trade shows, joint marketing and promotional campaigns and Web site linkage.

    Application and System Integrators. We have developed relationships with
several high-end network integration companies and system integrators from whom
we receive assistance with complex development, integration and project
management and for whom we provide application hosting and management
solutions. These relationships enable us to deliver more comprehensive Internet
application solutions to meet the needs of our customers.

    Internet Application Software Vendors. We have developed relationships with
some of the leading Internet application software vendors. We target Internet
application software vendors with brand name recognition and established sales
and support channels. These relationships are mutually beneficial, providing us
with additional applications to sell or rent to our customers and the software
vendors with a distribution channel for their applications. We also benefit
from cross-selling and co-marketing opportunities and specialized product
training to enhance our application management expertise.

Customers

    We were organized in 1996 by CMGI to support the networks and host the Web
sites of CMGI and a number of CMGI affiliates. In the Fall of 1997, we began
supplying Web site hosting and management services to companies unaffiliated
with CMGI. As of July 31, 1999, we had approximately 126 customers, up from 51
as of July 31, 1998. CMGI and CMGI affiliates accounted for 62% of our revenue
for the quarter ended July 31, 1999 as compared to 90% of our revenue for the
quarter ended July 31, 1998. CMGI and CMGI affiliates accounted for 15% of our
customer base as of July 31, 1999 as compared to 27% of our customer base as of
July 31, 1998.

    A representative list of our customers as of July 31, 1999 includes:
AltaVista Company; Ancestry.com, Inc.; Catalog City, Inc.; Engage Technologies,
Inc.; FairMarket, Inc.; Furniture.com, Inc.; Planet Direct Corporation; Raging
Bull, Inc.; Send.com; ThingWorld.com; and TribalVoice.

                                       39
<PAGE>

Product Development

    Our product development staff focuses on Internet applications and network
architecture. This group identifies new Internet applications, incorporates
these applications into our suite of service offerings and positions them for
marketing, sale and rapid deployment. We focus on Internet applications that
permit us to offer our customers repeatable, scalable services. Our goal is to
introduce services capable of utilization by a large number of customers,
maximizing revenue production and minimizing the incremental operating cost for
each additional customer utilizing that service. As new applications are
introduced, our personnel integrate the application into our management and
billing systems, provide technical documentation and training and ensure the
security of the offering. This process is critical to our ability to provide
integrated, scalable applications to our customers and is designed to result in
increased operating margins, faster product delivery and improved customer
service.

    Our product development group also identifies, selects and implements the
various technologies, including network storage and back-up, that provide the
basic infrastructure for both our internal network and the solutions we offer
our customers.

Customer Service and Support

    We believe customer service and support is critical to our future success
and growth. Our customer care staff is focused on direct and indirect customer
service and support. We have developed a customized, life-cycle project
management approach to our operations. For some of our customers, we assign a
single business solutions manager who services the customer from deployment
through the entire customer relationship. This approach is designed to enhance
our responsiveness to customer requests, problem troubleshooting and technology
upgrades. In servicing and supporting our customers, we utilize a number of
state-of-the-art automated systems, including a knowledge-based problem-
resolution and trouble-ticketing system, an enterprise system monitoring
platform, sophisticated data storage, an enterprise tape backup system and a
corporate intranet with a built-in document management and source control
system. We believe that our approach to customer service and support and our
ability to rapidly respond to customer needs provides us with a significant
competitive advantage.

Network Infrastructure, Technology and Operations

    NaviSite entered the Internet application service market with the advantage
of a well developed infrastructure established by CMGI to support CMGI and a
number of its affiliates. We have differentiated our infrastructure from
competing application service providers through our direct private transit
Internet connections to five major Internet backbone providers. We designed our
infrastructure specifically to provide superior performance for our Web site
and Internet application hosting and management services, including multi-level
network redundancy to provide the highest levels of network uptime, reliable
and customized network security and fast, guaranteed response time and
availability of customers' content, which we deliver through our private
transit Internet connections. Our infrastructure is also designed to scale to
support continued growth. We believe that our sophisticated and highly
redundant infrastructure provides us with a competitive advantage over other
hosting vendors and most Internet service providers. Key elements of our
infrastructure include:

    Data Centers. Our strategy is to build a select number of high performance
data centers in order to provide our customers with a critical mass of
expertise in Internet applications and management services from each data
center, while capturing the benefits of centralized infrastructure and
staffing. We currently have data centers located in Andover, Massachusetts and
Scotts Valley, California. These state-of-the-art data centers incorporate
technically sophisticated components and are designed to be completely fault-
tolerant. The components used in our data centers include Cisco redundant core
routers, Cisco redundant core switching hubs and secure, virtual local area
networks. We obtain the equipment and tools necessary for our data center
operations, including our infrastructure hardware, networking and software
products from industry leaders such as ArrowPoint Communications, Cisco
Systems, Compaq Computer Corporation, Dell, EMC and Oracle.

                                       40
<PAGE>

    We are adding new data centers, including an additional data center in
Andover and a new data center in San Jose, California. Construction is
currently underway at both of these new sites.

    Private Transit Internet Connectivity. Our use of direct private transit
Internet connections to five major Internet backbone providers differentiates
our network infrastructure from that of our competitors. We have redundant
high-capacity Internet connections to UUNet, CERFnet and MCI on the East Coast
and UUNet, BBN, MCI and SprintLink on the West Coast. We have deployed direct
private transit Internet connections specifically to avoid congestion and data
loss at public Internet exchange points and the resulting degradation of
performance. Our private transit system enables us to provide fast, reliable
access for our customers' Web sites and Internet applications. Because we have
direct private transit links to Internet providers, we can directly monitor the
capacity of all of our connections and guarantee that we will have the
aggregate bandwidth to move large quantities of data at high transmission
speeds. Our private transit Internet connections also enable us to more
effectively launch new applications, such as streaming, which require high
bandwidth availability and run more effectively in a private transit model.

    Service Level Guarantees. The combination of our state-of-the-art
infrastructure, our customer-focused operations group and our hosting and
management expertise enable us to offer our customers service levels backed by
guarantees that we believe are among the highest and most comprehensive in the
industry. For example, we offer our customers 99.99% guarantees for network
segments, our facility and facility components. These guarantees translate into
no more than five minutes of consecutive, unscheduled downtime per month.

    Network Security. Our network incorporates host-based security with
CheckPoint back-end firewalls and Cisco router access control lists, as well as
SecurID token-based authentication. In addition to these physical security
measures, we have a formal security policy in place, including employee
training, that governs all facets of our business and guidelines governing
internal and external access to information housed in our network system.

    Network Operations Centers. Each NaviSite data center has its own network
operations center on site. Each network operations center is fully staffed 24-
hours-a-day, seven-days-a-week with Windows NT, UNIX, application and support
personnel. Our network operations centers perform first-level problem
identification and resolution. The design of our network operations centers
allows network engineers and support personnel to be promptly alerted to
problems, and we have established procedures for rapidly resolving any
technical issues that arise. Network management and monitoring tools
continuously monitor the network and server performance.

Competition

    We compete in the Internet application service market. This market is
evolving rapidly, is highly competitive and is likely to be characterized by an
increasing number of market entrants and by industry consolidation. Because
there are no substantial barriers to entry, we expect that we will face
competition from both existing competitors and new market entrants in the
future. We believe that participants in this market must grow rapidly and
achieve a significant presence to compete effectively. We believe that the
primary competitive factors determining success in our market include:

  .   a state-of-the-art infrastructure providing availability, speed,
      scalability and security;

  .   Web site and Internet application hosting and management expertise;

  .   fast and reliable Internet connectivity;

  .   a reputation for high-quality service and superior customer service
      and support;

  .   numerous and diverse service offerings and timely addition of value-
      added services;

  .   brand recognition;

  .   competitive pricing; and

                                       41

  .   adequate capital to permit continued investment in infrastructure,
      customer service and support and sales and marketing.

As an early stage company, we may lack the financial and other resources,
expertise or capabilities to capture increased market share in this environment
in the future.

    Our current and prospective competitors include:

  .   other providers of co-location or high-end Web site hosting and
      related services, including AboveNet Communications, Inc., Digex
      Corporation, Exodus Communications, Inc., Frontier GlobalCenter Inc.,
      Globix Corporation, Interliant, Inc. and a large number of local and
      regional hosting providers;

  .   national and regional Internet service providers, including Concentric
      Network Corporation, MindSpring Enterprises, Inc., PSINet Inc., UUNet,
      WorldCom and Verio Inc.;

  .   companies that focus on customized Internet application services,
      including AppNet Systems, Inc., CORIO, Inc., IBM Global Services,
      USinternetworking, Inc. and USWeb/CKS;

  .   application developers and Internet application software vendors,
      including Open Market, Inc., DoubleClick Inc. and broadcast.com inc.;

  .   large system integrators and information technology outsourcing firms,
      including Electronic Data Systems Corporation and International
      Business Machines Corporation; and

  .   global telecommunications companies, including AT&T Corp., MCI
      WorldCom, Inc. and Sprint Corporation, and regional and local
      telecommunications companies, including MediaOne Group, Inc. and
      regional Bell operating companies, such as Bell Atlantic Corporation.

    Many of these competitors have substantially greater financial, technical
and marketing resources, larger customer bases, longer operating histories,
greater name recognition and more established relationships in the industry
than we have. As a result, many of these competitors may be able to develop and
expand their network infrastructures and service offerings more rapidly, adapt
to new or emerging technologies and changes in customer requirements more
quickly, take advantage of acquisitions and other opportunities more readily,
devote greater resources to the marketing and sale of their services and adopt
more aggressive pricing policies than we can. Because of these competitive
factors and due to our comparatively small size and our lack of financial
resources, we may be unable to successfully compete in the Internet application
service market.

    In addition, we believe that there will be continued consolidation within
the Internet application service market in which we compete. Our competitors
may consolidate with one another, or acquire software application vendors or
technology providers, enabling them to more effectively compete with us. This
consolidation could affect prices and other competitive factors in ways which
would impede our ability to compete successfully in the Internet application
service market.

Proprietary Rights

    We rely on a combination of trademark, service mark, copyright and trade
secret laws and contractual restrictions to establish and protect our
proprietary rights and promote our reputation and the growth of our business.
We do not own any patents that would prevent or inhibit competitors from using
our technology or entering our market. While it is our practice to require all
of our employees, consultants and independent contractors to enter into
agreements containing non-disclosure, non-competition and non-solicitation
restrictions and covenants, and while our agreements with some of our customers
and suppliers include provisions prohibiting or restricting the disclosure of
proprietary information, we can not assure you that these contractual
arrangements or the other steps taken by us to protect our proprietary rights
will prove sufficient to prevent misappropriation of our proprietary rights or
to deter independent, third-party development of similar proprietary assets. In
addition, we provide our services in other countries where the laws may not
afford adequate protection for our proprietary rights.

                                       42
<PAGE>

    We license or lease most technologies used in our Internet application
services. Our technology suppliers may become subject to third-party
infringement claims which could result in their inability or unwillingness to
continue to license their technology to us. The loss of certain of our
technologies could impair our ability to provide services to our customers or
require us to obtain substitute technologies of lower quality or performance
standards or at greater cost. We expect that we and our customers increasingly
will be subject to third-party infringement claims as the number of Web sites
and third-party service providers for Web-based businesses grows. In addition,
we have received notices alleging that our use of our service marks infringes
the trademark rights of third parties. Although we do not believe that any of
these allegations have merit, or that our technologies or services otherwise
infringe the proprietary rights of any third parties, we cannot assure you that
third parties will not assert claims against us in the future or that these
claims will not be successful. Any infringement claim as to our technologies or
services, regardless of its merit, could be time-consuming, result in costly
litigation, cause delays in service, installation or upgrades, adversely impact
our relationships with suppliers or customers or require us to enter into
royalty or licensing agreements.

Government Regulation

    While there currently are few laws or regulations directly applicable to
the Internet or to Internet application service providers, due to the
increasing popularity of the Internet and Web-based applications it is likely
that such laws and regulations may be adopted. These laws may cover a variety
of issues including, for example, user privacy and the pricing, characteristics
and quality of products and services. The adoption or modification of laws or
regulations relating to commerce over the Internet could substantially impair
the future growth of our business or expose us to unanticipated liabilities.
Moreover, the applicability of existing laws to the Internet and Internet
application service providers is uncertain. These existing laws could expose us
to substantial liability if they are found to be applicable to our business.
For example, we provide services over the Internet in many states in the United
States and in the United Kingdom, and we facilitate the activities of our
customers in those jurisdictions. As a result, we may be required to qualify to
do business, be subject to taxation or be subject to other laws and regulations
in these jurisdictions, even if we do not have a physical presence or employees
or property there. The application of existing laws and regulations to the
Internet or our business, or the adoption of any new legislation or regulations
applicable to the Internet or our business, could materially adversely affect
our financial condition and operating results.

Employees

    As of August 31, 1999, we had 217 employees. Of these employees, 110 were
principally engaged in operations, 53 were principally engaged in sales and
marketing, 21 were principally engaged in product development and 33 were
principally engaged in finance and administration. None of our employees is
party to a collective bargaining agreement and we believe our relationship with
our employees is good. We also employ consultants and independent contractors
on a regular basis to assist in the completion of projects and we outsource our
direct telemarketing sales force. It is our practice to require all of our
employees, consultants and independent contractors to enter into agreements
containing non-disclosure, non-competition and non-solicitation restrictions or
covenants.

Facilities

    Existing Facilities. Our executive offices are located at 100 Brickstone
Square, Andover, Massachusetts and occupy approximately 17,800 square feet of
the space leased by CMGI at that location. We also occupy approximately 22,000
square feet at 300 Federal Street, Andover, Massachusetts, pursuant to an
agreement that expires in 2007. Part of this facility is utilized for our East
Coast data center, which we recently expanded. We believe that this facility
has sufficient growth capacity for approximately the next 10 months.

    We also occupy approximately 14,100 square feet at 1700 Greens Hill Road,
Scotts Valley, California, part of which is utilized for our West Coast data
center, pursuant to an agreement that expires in 2002. We believe that this
facility has sufficient growth capacity for approximately the next six months.
We do not have any current intention to expand the Scotts Valley facility.

                                       43
<PAGE>

    In addition, we occupy four offices at 304 Park Avenue South, 11th Floor,
New York, New York, pursuant to an agreement that expires in March 2001. This
office space is utilized by sales and marketing personnel.

    New Facilities. In May 1999, we executed a 12-year lease for a new 150,000
square foot facility located at 400 Minuteman Road, Andover, Massachusetts,
which is currently being constructed to our specifications. Part of this
facility will be utilized for a new data center. We currently are finalizing
the terms of the construction contract for the new Massachusetts facility and
we anticipate that work will be completed on this facility in the Spring of
2000. We believe that the new Massachusetts facility will have sufficient
growth capacity for at least the next two years. Construction also has started
on a new 66,000 square foot facility located in the Valley Technology Centre,
2720 Zanker Road, San Jose, California, part of which will be utilized for a
new data center. We also currently are finalizing the terms of the construction
contract for the new California facility. This facility should be available for
occupation in the Fall of 1999. In May 1999, we executed a seven-year lease for
this facility.

    We believe that upon completion of the two new facilities currently under
construction, our facilities will be adequate for at least the next two years
and that we will be able to obtain additional space as needed on commercially
reasonable terms.

    NaviSite is not currently a party to any material legal proceedings.

Board Committees

    NaviSite's board of directors has an audit committee and a compensation
committee. The audit committee determines our accounting policies and practices
and financial reporting and internal control structures, recommends to the
board of directors the appointment of independent auditors to audit our

financial controls. The audit committee consists of Messrs. Goldman, Moore and

determining salaries, incentives and other forms of compensation for officers

and benefit plans. The compensation committee consists of Messrs. Goldman,

Director Compensation

    We do not currently pay any cash compensation to members of our board for
attending meetings of the board of directors or committee meetings, but we do
reimburse directors for their reasonable travel expenses incurred in connection
with attending these meetings. Any board member who is not also an officer or
employee of NaviSite, any subsidiary of NaviSite or CMGI is entitled to non-
statutory stock options under our 1998 Director Stock Option Plan.

    NaviSite has reserved for issuance 125,000 shares of common stock under the
1998 Director Stock Option Plan. As of August 31, 1999, options to purchase
75,000 shares of common stock were outstanding under the Director Stock Option
Plan. Options for 50,000 shares were granted with an exercise price of $0.34
per share, and options for the remaining 25,000 shares were granted at an
exercise price per share equal to the per share public offering price set forth
on the cover page of this prospectus. Effective as of October 8, 1999, no
further options will be granted under this plan. Commencing on December 28,
1998, the date that the Director Stock Option Plan was adopted, each non-
employee director of NaviSite was entitled to receive, upon the date of his or
her election, a non-statutory option to purchase 25,000 shares of common stock,
with the exception of Craig

                                       47
<PAGE>


Goldman, who was granted an option to purchase 50,000 shares of common stock
pursuant to the terms of the Director Stock Option Plan. The exercise price for
each automatic grant is equal to the fair market value of the common stock at
the time of grant, and each option has a maximum term of ten years, subject to
earlier termination following the optionee's cessation of service on the board
of directors. Each automatic option grant vests and becomes exercisable with
respect to 5,000 shares of common stock on the first anniversary of the date of
the grant, with the exception of the grant to Mr. Goldman, whose option vested
and became exercisable as to 10,000 shares on the date of grant. The remaining
option grant will become exercisable with respect to an additional 5,000 shares
(10,000 shares with respect to Mr. Goldman) on the date of each annual
stockholders' meeting at which the option holder is re-elected as a director.

    Effective as of October 8, 1999, we terminated the 1998 Director Stock
Option Plan and replaced it with the 1999 Stock Option Plan for Non-Employee
Directors, which was approved and adopted by our board of directors and our
stockholders in October 1999. A total of 250,000 shares of our common stock are
reserved for issuance under the new plan. Our directors who are not NaviSite
employees or otherwise affiliates, employees or designees of an institutional
or corporate investor that owns more than 5% of our outstanding common stock
are eligible to receive non-statutory stock options under the plan. Under the
new plan:

  .   we will grant an initial option to acquire 25,000 shares of our common
      stock to each eligible director who is elected a director for the
      first time after the plan is adopted on the date of that election;

  .   our board may, in its discretion, grant initial options to eligible
      directors first elected to our board prior to approval of the new plan
      by our stockholders on the date stockholder approval is obtained; and

  .   we also will grant an initial option to acquire 25,000 shares of our
      common stock to each director who

     .   ceases being an affiliate, employee or designee of an
         institutional or corporate investor that owns more than 5% of our
         outstanding common stock and

     .   is not otherwise an employee of us or any of our subsidiaries but

     .   remains as a member of our board on the date the director's
         affiliate, employee or designee status ceases.

We also will grant to eligible directors an additional option for the purchase
of 6,250 shares of our common stock on the first, and each subsequent,
anniversary of the grant of each director's initial option if the director is
still serving as one of our directors on that anniversary date. Our board has
discretion to increase to up to 100,000 shares the number of shares of common
stock subject to any initial option or additional option covering any vesting
period of up to 48 months that may be granted to an eligible director after the
date of the increase.

    The per share exercise price of options granted under the new plan will be
equal to the closing price of our common stock on a national securities
exchange or as quoted on the Nasdaq National Market, the average of the closing
bid and asked prices of our common stock in the over-the-counter market or the
fair market value of our common stock as determined by our board. Each initial
option granted under the new plan will vest and become exercisable as to 1/48th
of the number of shares originally subject to the option on each monthly
anniversary date of the date of grant if the optionee is still serving as a
director on that monthly anniversary date. Each additional option granted under
the new plan will vest and become exercisable as to 1/12th of the number of
shares originally subject to the option on each monthly anniversary date of the
date of grant commencing on the 37th monthly anniversary date if the optionee
is still serving as a director on that monthly anniversary date. All
outstanding options granted under the new plan immediately become exercisable
in full upon a change in control of NaviSite.

Stock Option Grants

    The following table sets forth information regarding options granted to the
executive officers named in the "Summary Compensation" table appearing above
during the fiscal year ended July 31, 1999. The exercise price per share of
each option is equal to the fair market value of the common stock of NaviSite
or CMGI, as applicable, on the date of grant as determined by the board of
directors. Potential realizable values set forth in the table are net of the
exercise price but before taxes associated with the exercise, are calculated
based on rules of the Securities and Exchange Commission and do not represent
an estimate or projection of future common stock prices. Actual gains, if any,
on stock option exercises are dependent on the future performance of NaviSite's
or CMGI's common stock, as applicable, overall stock market conditions and the
option-holders' continued employment with NaviSite through the vesting period.
The potential realizable values reflected in the table may not necessarily be
achieved. We have never granted any stock appreciation rights.

(1)  The value of unexercised in-the-money options is based upon the per share
     fair market value of the underlying stock on the date of exercise, minus
     the per share exercise price of the option, multiplied by the number of
     shares of stock underlying the option. With respect to the NaviSite
     options, the value of unexercised in-the-money options is based upon an
     assumed initial public offering price of $11.00 per share, minus the
     applicable option exercise price, multiplied by the number of shares of
     common stock underlying the option. With respect to the CMGI options, the
     value of unexercised in-the-money options is based on the difference
     between $92.19, which was the closing price of CMGI common stock on July
     31, 1999, and the applicable option exercise price. With respect to the
     NaviNet options, the value of unexercised in-the-money options is based on
     the difference between $1.65, which was the fair market value per share of
     the NaviNet common stock on July 31, 1999, as determined by an independent
     third-party valuation consultant, and the applicable option exercise
     price.

Employment and Non-Competition Agreements

    None of our executive officers has an employment agreement, although all of
our executive officers have entered into agreements that contain non-
disclosure, non-competition and non-solicitation restrictions and covenants,
including a provision prohibiting these officers from competing with NaviSite
during their employment with us and for a period of 12 months after termination
of their employment with us.

    In addition, each executive officer is party to an offer letter with CMGI
which sets forth his or her annual salary, annual bonus eligibility, option
grants and other benefits. Joel Rosen's offer letter, dated April 14, 1999,
provides that if he is terminated without cause or there is a substantive
change in his job title, responsibilities or location of employment, or a
reduction in his compensation, following a change of control of either NaviSite
or CMGI, then his options to purchase 534,166 shares of NaviSite common stock
and 100,000 shares of CMGI common stock will immediately become fully vested
and exercisable. Upon completion of this offering, NaviSite is assuming the
obligations applicable to NaviSite under these offer letters.

1998 Equity Incentive Plan

    NaviSite has reserved 5,562,212 shares of common stock for issuance under
the NaviSite 1998 Equity Incentive Plan, as amended and restated as of October
8, 1999. Under the Equity Incentive Plan, NaviSite is authorized to grant
incentive stock options, non-statutory stock options, stock appreciation rights
and restricted stock awards to employees, directors and consultants of
NaviSite, or any affiliate, who is capable of contributing significantly to our
successful performance. In general, options granted pursuant to the 1998 Equity
Incentive Plan are exercisable within four years of 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 any award or provide for cash
payments to the participants in exchange for their awards upon a change of
control of NaviSite. Options are not assignable or transferable except by will
or the laws of descent or distribution. Our board of directors may amend,
suspend or terminate the Equity Incentive Plan at any time, subject to any
required stockholder approval.

    As of August 31, 1999, options to purchase an aggregate of 2,564,161 shares
of common stock at a weighted average exercise price of $3.03 per share were
outstanding under the Equity Incentive Plan. As of August 31, 1999, we had not
granted any stock appreciation rights or issued any shares of restricted stock
under the Equity Incentive Plan.

1999 Employee Stock Purchase Plan

    The 1999 Employee Stock Purchase Plan was approved and adopted by our board
of directors and our stockholders in October 1999, to be effective upon
completion of this offering. The 1999 Employee Stock Purchase Plan provides for
the issuance of a maximum of 50,000 shares of our common stock.

    The 1999 Employee Stock Purchase Plan will be administered by the
compensation committee. All employees of NaviSite who have been employed by us
for at least six months and whose customary employment is for more than 20
hours per week and for more than five months in any calendar year are eligible
to participate in the 1999 Employee Stock Purchase Plan. Employees who would
own five percent or more of the total combined voting power or value of
NaviSite's stock immediately after having subscribed for shares under the 1999
Employee Stock Purchase Plan 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% of a participant's total cash compensation) from his or her pay
during each three-month payment period, with the exception of the first payment
period, which will commence upon the closing of this offering and end on
February 29, 2000. At the end of each payment period, except for the first
payment period following this offering, the participant's funds are used to
purchase shares of our common stock at a price equal to 85% of the lesser of
the last reported sale price of the common stock on the first or last business
day of the payment period. With respect to the first payment period following
this offering, the price will be equal to 85% of the lesser of the per share
public offering price set forth on the cover page of this prospectus or the
last reported sale price of the common stock on the last business day of the
payment period.

401(k) Plan

    NaviSite is a participating employer in the 401(k) defined contribution
profit sharing savings and retirement plan sponsored by CMGI. All NaviSite
employees who are at least 21 years of age and have satisfied the necessary
service eligibility requirements, except for nonresident aliens with no United
States source of income, are eligible to participate in the plan. Under our
401(k) plan, a participant employee may elect to reduce his or her current
compensation by up to the lower of 15% or the statutorily prescribed limit
($10,000 in 1999) and have the amount of the reduction contributed to the plan
on the employee's behalf as salary deferral contributions. The 401(k) plan
permits additional discretionary matching contributions by us with respect to
our employees' pre-tax contributions up to the first six percent of each
employee's salary contributed to the plan. The 401(k) plan also permits us to
make discretionary profit sharing contributions to the plan on behalf of our
employees. All contributions to the 401(k) plan by or on behalf of employees
are subject to aggregate annual limits prescribed by the Internal Revenue
Service.

Deferred Compensation Plan

    A Deferred Compensation Plan was approved and adopted by our board of
directors in October 1999, to be effective upon completion of this offering.
Under the terms of the deferred compensation plan, NaviSite employees who are
selected by our board of directors (as well as certain of our employees who
previously participated in a deferred compensation plan sponsored by CMGI) will
be able to elect to defer a portion of their compensation for the following
calendar year. Participants in the plan will be able to defer up to 25% of
their salary and 100% of their bonus compensation, which amounts will be paid
out at a later date at the participant's election. NaviSite also may make
discretionary contributions to a participant's account, to which the
participant generally will become entitled after five years of service with us.
NaviSite will maintain a bookkeeping account to track deferred amounts, which
amounts will be credited with gains or losses based on the performance of
deemed investment alternatives made available to participants under the plan.

Compensation Committee Interlocks and Insider Participation

    Prior to this offering, we had no separate compensation committee or other
board committee performing equivalent functions. These functions were performed
by our board of directors, which consisted of Joel B. Rosen and Robert B.
Eisenberg, our Chief Executive Officer and President, respectively, David S.
Wetherell, Chairman of the Board, President, Chief Executive Officer and
Secretary of CMGI, Craig D. Goldman, a director of CMGI, and Andrew J. Hajducky
III, Chief Financial Officer and Treasurer of CMGI.

                              CERTAIN TRANSACTIONS

Relationship and Transactions between NaviSite and CMGI, Inc.

    Our predecessor was incorporated in February 1997 as a wholly owned
subsidiary of CMGI. As of August 31, 1999, CMGI owned approximately 89.6% of
our common stock, including shares of convertible preferred stock held by CMGI
indirectly through our predecessor, which merged with and into CMGI effective
as of October 1, 1999. CMGI will directly own approximately 72.1% of our common
stock upon completion of this offering.

    CMGI has the power to elect our entire board of directors and to approve or
disapprove any corporate transactions or other matters submitted to our
stockholders for approval, including the approval of mergers or other
significant corporate transactions. CMGI may exercise its voting power by
written consent, without convening a meeting of the stockholders, meaning that
CMGI will be able to effect a sale or merger of NaviSite without prior notice
to, or the consent of, our other stockholders. CMGI also holds a majority
equity ownership position in many of our customers.

    NaviSite and CMGI have entered into or, upon or prior to completion of this
offering, will enter into the present and prospective arrangements and
transactions described below. These agreements were or will be negotiated
between CMGI, as a corporate parent, and NaviSite, its subsidiary, and
therefore are not the result of negotiations between independent parties.
NaviSite and CMGI intend that these agreements and the transactions provided
for in these agreements, taken as a whole, accommodate their respective
interests in a manner that is fair to both NaviSite and CMGI. However, because
of the complex nature of the various relationships among NaviSite, CMGI and
various CMGI affiliates, we cannot assure you that each of the agreements
described below, or the transactions provided for in these agreements, were or
will be effected on terms at least as favorable to NaviSite as NaviSite could
have obtained from unaffiliated third parties.

    NaviSite and CMGI or its affiliates may enter into additional or modified
arrangements and transactions in the future. NaviSite, CMGI or its affiliates,
as the case may be, will negotiate the terms of such arrangements and
transactions. Upon or prior to completion of this offering, NaviSite expects to
adopt a policy that all future arrangements between NaviSite and CMGI or its
affiliates, other than routine commercial transactions entered into in the
ordinary course of business, will be on terms that NaviSite believes are no
less favorable to it than the terms NaviSite believes would be available from
unaffiliated parties and must be approved by a majority of NaviSite'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 NaviSite and CMGI or its affiliates.

 Leases, Construction Contracts and CMGI Guarantees

    In connection with our execution of three of our real property leases, CMGI
has provided our landlords with guarantees of all of our obligations under the
leases. In connection with the execution of the lease for our Scotts Valley,
California facility, CMGI guaranteed the full performance of all of our
obligations through the expiration of the lease term. In connection with the
execution of the lease for our new Andover, Massachusetts facility, CMGI
executed an unconditional guaranty of the lease and an accompanying letter of
credit to ensure the full and punctual payment, as well as performance of all
of our obligations, under the lease. CMGI will be released from the Andover
guaranty upon the occurrence of the earlier of the closing of this offering or
the date on which we occupy the premises and begin to pay rent. CMGI also
executed an unconditional and irrevocable guaranty in connection with the
execution of the lease for our new facility in San Jose, California. CMGI will
be released from the San Jose lease guaranty within 15 days of the later of the
closing of this offering and the landlord's receipt of a letter of credit, in
the form specified in the guaranty, in the amount of approximately $2.4
million.

                                       54
<PAGE>


    We also currently are finalizing construction contracts in connection with
our new facilities in Andover, Massachusetts and San Jose, California. If we
execute either or both of these contracts prior to the completion of this
offering, CMGI will be required to execute a guarantee on our behalf with
respect to each executed contract. Each contract provides that CMGI will be
released from any related guarantee upon the completion of this offering. In
connection with the construction contract for the new Andover, Massachusetts
facility, we will be required, upon CMGI's release from its guarantee or, if
the contract is executed after the completion of this offering, upon execution
of the contract, to obtain a letter of credit in the amount of the remaining
balance due under the contract, which is currently estimated to be less than
$15 million.

    In addition, certain of the equipment that we use or provide to our
customers for their use in connection with our services is provided under
leases executed or guaranteed by CMGI. If CMGI discontinues this practice,
which it could do at any time, we or our customers would have to obtain this
equipment directly, and we cannot assure you that we or our customers could do
so on similar financial terms.

 Debt Conversion

    We have issued a secured convertible demand note to CMGI in exchange for
the cancellation of all intercompany debt incurred by us to CMGI subsequent to
the conversion of CMGI debt into Series A convertible preferred stock and prior
to April 30, 1999. This note also provides for additional advances by CMGI to
us after April 30, 1999. CMGI may elect to convert amounts payable under the
note into Series B convertible preferred stock at any time. Additional
intercompany debt incurred after April 30, 1999 accrues interest at a rate of
seven percent per year, compounded monthly until the day CMGI elects to convert
the debt into shares of Series B convertible preferred stock. The amount of
each borrowing represented by the note is convertible from time to time into
the number of shares of Series B convertible preferred stock equal to one-tenth
of the quotient of:

  .  the aggregate amount of principal and interest to be so converted,
     divided by

  .  the applicable conversion price for that fiscal quarter.

    The conversion price applicable to advances made in any fiscal quarter,
except advances made in the fiscal quarter during which a qualified initial
public offering occurs and advances converted into Series B convertible
preferred stock in the same fiscal quarter in which they were made, is
determined by dividing our total enterprise value as of the fiscal quarter end,
as determined in good faith by our board of directors, by the number of shares
of common stock outstanding on a fully diluted, as-if-converted basis. Each
share of Series B convertible preferred stock issued and outstanding will
convert into ten shares of common stock upon the completion of this offering.

    Under this note, intercompany debt in the aggregate amount of approximately
$10,761,000, representing $5,348,000 advanced during the quarter ended January
31, 1999 and an additional $5,413,000 advanced during the quarter ended April
30, 1999, in each case including interest accrued during the applicable fiscal
quarter, was converted into 490,332 shares of Series B convertible preferred
stock (based upon applicable conversion prices of $12.74 and $76.68,
respectively). Effective June 4, 1999, CMGI elected to convert intercompany
debt in the aggregate amount of approximately $3,952,000, representing funds
advanced subsequent to the quarter ended April 30, 1999, into 51,527 shares of
Series B convertible preferred stock (based upon a conversion price of $76.68).
Under the terms of the note, because CMGI elected to convert these advances
prior to the end of the fiscal quarter in which the advances were made, the
applicable conversion price was the conversion price in effect for the
immediately preceding fiscal quarter. Immediately prior to the completion of
this offering, CMGI will convert intercompany debt in the aggregate amount of
approximately $12,257,000, representing funds advanced subsequent to the
quarter ended July 31, 1999, into 111,424 shares of Series B convertible
preferred stock (based upon a conversion price of $110, assuming an initial
public offering price of $11.00 per share). Upon completion of this offering,
the 653,283 shares of Series B convertible preferred stock issued and
outstanding will convert into 6,532,830 shares of common stock. We do not
expect to borrow funds from CMGI after completion of this offering.

    This note is secured by all of our intellectual property and other assets,
whether now owned or hereafter acquired, under the terms of an intellectual
property security agreement and a security agreement between us and CMGI.

 Facilities and Administrative Support Agreement

    Upon completion of this offering, we will enter into a facilities and
administrative support agreement with CMGI under which CMGI will continue to
make available to us space at its headquarters in Andover, Massachusetts and
will provide various services to us, including: accounting, systems and related
services; rent and facilities; human resources and benefits; and Internet
marketing and business development.

    Under this agreement, CMGI also will agree to make available to us at least
17,800 square feet of space at its headquarters until completion of our new
Andover, Massachusetts facility. We intend to relocate our executive offices to
our new facility upon completion of that facility.

    The initial term of this agreement will be one year from the date of the
agreement, with automatic renewals at the end of the initial term and each
renewal term for successive one-year periods. Either party will be permitted to
terminate the facilities and administrative support agreement upon prior
written notice. The facilities and administrative support agreement will
automatically terminate upon the date CMGI owns less than 50% of our
outstanding common stock.

    The fees payable by us for the availability of space and other services are
typically determined through an allocation of CMGI's costs based upon the
proportion of our employee headcount to the total headcount of CMGI and other
CMGI affiliates located in the same facility or using the same services. Under
the facilities and administrative support agreement, we will pay CMGI a monthly
fee reflecting the cost of the services provided by CMGI based on the total
number of our employees and consultants on the last day of that month.

    In fiscal 1997, fiscal 1998 and fiscal 1999, we paid CMGI $48,000, $289,000
and $1,346,000, respectively, for services similar to those to be provided
under the facilities and administrative support agreement.

 Tax Allocation Agreement

    Upon completion of this offering, we will enter into a tax allocation
agreement with CMGI to allocate responsibilities, liabilities and benefits
relating to taxes. We will be required to pay our 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 as of which we 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 us against liability for all taxes in
respect of consolidated, combined or unitary tax returns for periods as to
which CMGI is filing group returns which include us. Accordingly, any
redetermined tax liabilities for those periods will be the responsibility of
CMGI, and any refunds or credits of taxes attributable to us or our
subsidiaries in respect of consolidated, combined or unitary tax returns for
those periods will be for the account of CMGI. We 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, with
respect to separately filed tax returns. We will indemnify CMGI against any tax
liability with respect to separately filed tax returns.

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

                                       56
<PAGE>

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

 Investor Rights Agreement

    Upon completion of this offering, we will enter into an investor rights
agreement with CMGI under which we 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 two
occasions, that NaviSite register the sale of all or part of their shares of
our common stock having an aggregate value of at least $10.0 million under the
Securities Act. In addition, at any time after we become eligible to file a
registration statement on Form S-3 under the Securities Act, CMGI and its
assignees will have the right to request, on up to five occasions, that we
effect a registration of their shares of our common stock having an aggregate
value of at least $2.5 million on Form S-3. CMGI and its assignees also are
entitled to include shares of our common stock in a registered offering by us
of our securities for our own account, subject to the underwriters' right to
reduce the number of included shares. We will pay all costs associated with the
registration of shares by us 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 our capital stock, we will permit CMGI, or the transferee, to purchase a
portion of any shares that we may in the future issue so that CMGI or the
transferee will 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 our common stock.

 Other Transactions with CMGI and its Affiliates

    We have agreements with numerous CMGI affiliates under which we provide
these affiliates with Web site and Internet application hosting services,
together with enhanced server management for both Web sites and Internet
applications and specialized application management services. We also rent
sophisticated software applications to a number of these affiliates and provide
consulting services to each of these affiliates on an as-needed basis.

    Our existing service agreements with CMGI affiliates are routine commercial
transactions entered into in the ordinary course of our business. We anticipate
that we will continue to enter into routine commercial transactions with CMGI
and its affiliates in the future. Currently, however, we have no long-term
contracts, right-of-first-refusal arrangements, business opportunity allocation
agreements or other material contractual arrangements or understandings with
CMGI or any of its affiliates regarding the continued sale of our services to
CMGI or its affiliates.

    In general, in pricing the services provided to CMGI and its affiliates, we
have: negotiated the services and levels of service to be provided; calculated
the price of the services at those service levels based on our then-current,
standard prices; and discounted these prices by 10%. This pricing policy is not
dictated by or provided for in any contractual arrangement. The discounts we
provide to CMGI and its affiliates, which also are available to industry
partners and other parties engaged in co-marketing or referral arrangements
with us, are afforded to CMGI and, at CMGI's direction, its affiliates because
of CMGI's customer referral relationship with us. Although there are no
agreements to this effect between us and CMGI, we expect both our customer
referral relationship with CMGI and the discounted pricing for services
provided to CMGI and its affiliates to continue after completion of this
offering.

    The chart set forth below lists the CMGI affiliates from which we derived
revenue in excess of $60,000 in each of the last three fiscal years and the
revenue derived from these CMGI affiliates for the fiscal years ended July 31,

$4,029,000 and $10,519,000, for the fiscal years ended July 31, 1997, 1998 and
1999, respectively.

Servercast Communications, L.L.C. Acquisition

 Term Notes

    In connection with our acquisition in July 1998 of Servercast, we issued
four term notes to the members of Servercast in the aggregate principal amount
of $1.0 million, payable on or before January 2, 2000, in exchange for all of
the membership interests in Servercast. CMGI has guaranteed the payment of each
of these term notes. CMGI's guarantee will terminate upon the earliest to occur
of (i) the closing of this offering, (ii) the sale of NaviSite to an acquiror
with a net worth of at least $15 million and (iii) the payment by us of all
amounts owed under the term notes.

    One of these term notes, in the principal amount of $279,100, was issued to
Peter C. Kirwan, Jr., our Chief Technology Officer, in exchange for his 27.91%
membership interest in Servercast. The note bears interest at the rate of 5.5%
per year (calculated on the basis of a 365-day year and the actual number of
days elapsed). The note provides that accrued interest will be paid in three
equal installments of $7,675.25 each, to be paid on January 2, 1999, July 2,
1999 and January 2, 2000. The first and second scheduled payments of

                                       58
<PAGE>

$7,675.25 each were made in full on January 2, 1999 and July 2, 1999,
respectively. Mr. Kirwan has agreed that payment of accrued interest or
principal may be offset by claims for indemnification that we may have pursuant
to the terms of the related purchase agreement and that 20% of any principal
amount paid prior to July 1, 2000 shall be delivered into an escrow fund for
the purpose of funding Mr. Kirwan's indemnification obligations to us.

 Bonus Agreement

    In connection with our acquisition of Servercast, we also entered into a
bonus agreement dated as of July 1, 1998 with Mr. Kirwan. The bonus agreement
provides that Mr. Kirwan will receive an incentive bonus payment if established
targets are met relating to the revenues and operating losses of Servercast for
the one-year period ended July 1, 1999. The maximum amount which Mr. Kirwan
could receive pursuant to the bonus agreement is $231,187. Pursuant to the
terms of the bonus agreement and the related purchase agreement, 20% of any
bonus amount due to Mr. Kirwan as of July 1, 1999 shall be delivered into the
escrow fund described above. In order to be eligible for the incentive bonus
and the return of any escrowed amount, Mr. Kirwan must remain an employee of
NaviSite through July 1, 1999 and July 1, 2000, respectively, unless he either
terminates his employment with just cause or is terminated by us without cause,
in which case he remains entitled to any bonus payments or escrowed amounts
due. Mr. Kirwan remains an employee of NaviSite, and we are currently in the
process of comparing actual revenues and operating losses against the targets
established in the bonus agreement to determine any bonus payment due to Mr.
Kirwan as of July 1, 1999.

    Pursuant to the bonus agreement, we also granted Mr. Kirwan non-statutory
stock options to purchase 50,000 shares of our common stock, at an exercise
price of $0.93 per share. One fourth, or 12,500, of the options vested and
became fully exercisable on July 1, 1999, and the remainder vest ratably at the
end of each month for 36 months, provided that Mr. Kirwan continues to be
employed by us.

               OWNERSHIP OF PRINCIPAL STOCKHOLDERS AND MANAGEMENT

    Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. Except as indicated by the footnotes below,
we believe, based on the information furnished to us, that the persons and
entities named in the tables below have sole voting and investment power with
respect to all shares of common stock shown as beneficially owned by them,
subject to applicable community property laws. Percentage of outstanding shares
of NaviSite common stock is based on 20,816,173 shares of common stock
outstanding as of August 31, 1999, and 27,430,413 shares of common stock
outstanding upon completion of this offering. Percentage of outstanding shares
of CMGI common stock is based on 114,582,987 shares of common stock outstanding
as of August 26, 1999. In computing the number of shares of common stock
beneficially owned by a person and the percentage ownership of that person,
shares of common stock subject to options held by that person that are
currently exercisable or exercisable within 60 days of August 31, 1999 are
deemed outstanding. These shares, however, are not deemed outstanding for the
purpose of computing the percentage ownership of any other person.

Principal Stockholders

    The following table sets forth information with respect to the beneficial
ownership of our common stock by our principal stockholders as of August 31,
1999 and as adjusted to reflect the sale of the shares of common stock offered
in this offering. The outstanding shares of common stock shown as held by CMGI
as of August 31, 1999 include shares issued upon completion of the corporate
reorganization of NaviSite Internet Services Corporation, effective as of
October 1, 1999, and conversion of convertible preferred stock held by CMGI as
of August 31, 1999. The percentage ownership of CMGI after this offering
reflects the issuance to CMGI of an aggregate of 1,114,240 additional shares of
common stock upon the conversion of outstanding Series B convertible preferred
stock.

    The following description of our capital stock and various provisions of
our revised certificate of incorporation and our revised by-laws is a summary.
Statements contained in this prospectus relating to such provisions are not
necessarily complete, and reference is made to the revised certificate of
incorporation and the revised by-laws that will become effective upon the
completion of this offering, copies of which have been filed with the
Securities and Exchange Commission as exhibits to our registration statement of
which this prospectus constitutes a part.

    Upon completion of this offering, our authorized capital stock will consist
of 150,000,000 shares of common stock, par value $0.01 per share, and 5,000,000
shares of preferred stock, par value $0.01 per share.

Common Stock

    As of August 31, 1999, there were 20,816,173 shares of common stock
outstanding, held of record by four stockholders. Upon completion of this
offering, there will be 27,403,413 shares of common stock outstanding. In
addition, as of August 31, 1999, there were outstanding stock options for the
purchase of a total of 2,639,161 shares of common stock. Shares of common stock
have the following rights, preferences and privileges:

    Voting Rights. Each outstanding share of common stock is entitled to one
vote on all matters submitted to a vote of NaviSite's stockholders, including
the election of directors. There are no cumulative voting rights, and therefore
the holders of a plurality of the shares of common stock voting for the
election of directors may elect all of NaviSite's directors standing for
election.

    Dividends. Holders of common stock are entitled to receive dividends at the
same rate if and when dividends are declared by NaviSite's board of directors
out of assets legally available for the payment of dividends, subject to
preferential rights of any outstanding shares of preferred stock.

    Liquidation. In the event of a liquidation, dissolution or winding up of
the affairs of NaviSite, whether voluntary or involuntary, after payment of the
debts and other liabilities of NaviSite and making provision for the holders of
any outstanding shares of preferred stock, the remaining assets of NaviSite
will be distributed ratably among the holders of shares of common stock.

    Rights and Preferences. The common stock has no preemptive, redemption,
conversion or subscription rights. 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 we may designate and issue in the future.

    Fully Paid and Nonassessable. All outstanding shares of common stock are,
and the shares of common stock to be issued pursuant to this offering will be,
fully paid and nonassessable.

Preferred Stock

    Upon completion of this offering, it is expected that all outstanding
shares of preferred stock will be converted into common stock. Pursuant to the
terms of our revised certificate of incorporation, 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 classes or series, and to
fix the voting powers, full or limited, or no voting powers, and the
distinctive designations, preferences and relative, participating, optional or
other special rights and the qualifications, limitations or restrictions of
these rights, of the shares of each such class or 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.

                                       62
<PAGE>

    We have 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 attempting to acquire, a majority of our
outstanding common stock.

Registration Rights

    Under the terms of the Series C and the Series D convertible preferred
stock purchase agreements entered into between us and each of the Series C
stockholder and the Series D stockholder, respectively, effective upon
completion of this offering, assuming the conversion of the preferred stock
held by the Series C stockholder and the Series D stockholder into common
stock, these stockholders, together with their permitted assignees,
collectively the holders of an aggregate of 2,088,715 shares of our common
stock, will have the right to register some or all of their shares under the
Securities Act under specified conditions. At any time after the six-month
anniversary of the closing of this offering, the holders of at least 50% of the
Series C shares or at least 50% of the Series D shares, as applicable, are
entitled to demand that we file a registration statement under the Securities
Act covering the registration of some or all of their shares, subject to
specified limitations. Under these demand registration rights, we are only
obligated to effect two registrations for each of the Series C stockholder,
together with its permitted assignees, and the Series D stockholder, together
with its permitted assignees. In addition, pursuant to the terms of the Series
C convertible preferred stock purchase agreement and the Series D convertible
preferred stock purchase agreement, after the completion of this offering, the
Series C and Series D stockholders will have unlimited incidental registration
rights in the event that we propose to register any shares of common stock
under the Securities Act, either for our own account or for the account of
other security holders. The Series C and Series D stockholders having
incidental registration rights are entitled to receive notice of any such
registration and are entitled to include their shares in the registration,
subject to specified limitations.

    In addition, at any time after the earlier of the one-year anniversary of
the closing of this offering or such time as we become eligible to file a
registration statement on Form S-3, the holders of at least 50% of the Series C
shares or at least 50% of the Series D shares, as applicable, are entitled to
require us to file a registration statement on Form S-3 covering their shares
of common stock. We will not be obligated to effect more than two Form S-3
registrations on behalf of either the Series C stockholder or the Series D
stockholder. These registration rights are subject to customary conditions and
limitations, including the right of the underwriters of an offering to limit
the number of shares of common stock held by security holders with registration
rights to be included in that registration. We also may defer a request for
registration for a period of not more than 90 days, subject to specified
conditions, if our board of directors determines that the requested
registration would be materially detrimental to us and our stockholders. We
generally are required to bear all of the expenses of all of the registrations
effected under the convertible preferred stock purchase agreements, excluding
underwriting discounts and commissions.

    The registration of any of the shares of common stock held by stockholders
with registration rights would result in these shares becoming freely tradeable
without restriction under the Securities Act immediately upon effectiveness of
that registration statement. Information regarding the registration rights of
CMGI is included in this prospectus under the heading "Certain Transactions--
Relationship and Transactions Between NaviSite and CMGI, Inc.--Investor Rights
Agreement."

Participation Rights

    Under the terms of the Series C convertible preferred stock purchase
agreement and the Series D convertible preferred stock purchase agreement
entered into between us and each of the Series C stockholder and the Series D
stockholder, respectively, we agreed that, in connection with certain
underwritten public offerings of our common stock, which would include this
offering assuming the conversion of the preferred stock held by the Series C
and the Series D stockholders into common stock, we would use all commercially
reasonable efforts to require that the underwriters offer to each of the Series
C stockholder and the Series D stockholder shares of the common stock to be
sold in the offering. Under these agreements, each of the Series C stockholder
and the Series D stockholder would be permitted to purchase, at the gross price
per share

                                       63
<PAGE>

negotiated by us with the underwriters of the offering as reflected in the
final prospectus, up to an aggregate of 0.5% of the outstanding shares of our
common stock on a fully diluted basis, after giving effect to the sale of
shares of common stock in the offering. In connection with an offering to which
these participation rights are applicable, we agreed to deliver or cause to be
delivered a copy of the preliminary prospectus for the offering to both the
Series C stockholder and the Series D stockholder simultaneously with the
distribution of same to the public at large by the underwriters. The Series C
stockholder and the Series D stockholder each then are entitled to exercise its
respective right of participation by delivering written notice to us not later
than five business days prior to the pricing of the offering. The underwriters
of the offering then are entitled to reduce the number of shares of common
stock to be offered to the Series C stockholder and the Series D stockholder to
the extent deemed necessary in the underwriters' reasonable judgment to ensure
the success of such offering or to comply with applicable rules and
regulations. Because, notwithstanding our commercially reasonable efforts, it
is not possible under applicable law to sell shares to the Series C stockholder
and Series D stockholders in this offering, the Series C stockholder and the
Series D stockholder have waived their respective rights to participate.

Delaware Anti-Takeover Statute

    Our revised certificate of incorporation 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 or their affiliates. An interested stockholder is
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. Because of this election, Section 203 will
not apply to us.

Limitation of Liability and Indemnification

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

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

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

  .   unlawful payments of dividends or unlawful stock repurchases or
      redemptions; or

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

This provision has no effect on any non-monetary remedies that may be available
to us or our stockholders, nor does it relieve us or our officers or directors
from compliance with federal or state securities laws.

    Our revised certificate of incorporation also generally provides that we
will indemnify, to the fullest extent permitted by Section 145 of the Delaware
General Corporation Law, any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit,
investigation, administrative hearing or any other proceeding by reason of the
fact that he or she is or was a director or officer of ours, or is or was
serving at our request as a director, officer, employee or agent of another
entity, against expenses incurred by him or her in connection with that
proceeding. An officer or director will not be entitled to indemnification by
us if:

  .   the officer or director did not act in good faith and in a manner
      reasonably believed to be in, or not opposed to, our best interests;
      or

  .   with respect to any criminal action or proceeding, the officer or
      director had reasonable cause to believe his or her conduct was
      unlawful.

    In addition, we plan to enter into indemnification agreements with our
directors containing provisions which may require us, among other things, to
indemnify our 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

                                       64
<PAGE>

proceeding against them as to which they could be indemnified. Insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers or persons controlling NaviSite pursuant to
the foregoing provisions or otherwise, NaviSite has been informed 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.

    NaviSite's revised certificate of incorporation also permits NaviSite to
secure insurance on behalf of any officer or director for any liability arising
out of his or her actions in such capacity, regardless of whether our revised
certificate of incorporation would otherwise permit indemnification for that
liability. Our officers and directors are currently insured under a policy
procured by CMGI that provides coverage against losses arising from claims
against them for any actual or alleged act, omission, misstatement, misleading
statement, neglect, error or breach of duty by them in their capacity as
officers or directors of NaviSite. We also have obtained our own liability
insurance for our officers and directors effective as of September 20, 1999.

    At the present time, there is no pending litigation or proceeding involving
any director, officer, employee or agent of NaviSite in which indemnification
will be required or permitted. We are not aware of any threatened litigation or
proceeding which may result in a claim for such indemnification.

Transfer Agent and Registrar

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

                        SHARES ELIGIBLE FOR FUTURE SALE

Effect of Sales of Shares

    Prior to this offering, no public market existed for our common stock, and
we can make no prediction as to the effect, if any, that sales of shares of
common stock or the availability of shares of our common stock for sale will
have on the market price of the common stock prevailing from time to time.
Nevertheless, sales of substantial amounts of our common stock in the public
market, or the perception that such sales occur, could adversely affect the
market price of our common stock and could impair our future ability to raise
capital through an offering of our equity securities.

Sale of Restricted Shares

    Upon completion of this offering, we will have an aggregate of 27,453,409
shares of common stock outstanding (including 22,996 shares issued in October
1999 upon the exercise of outstanding options). Of these outstanding shares,
the 5,500,000 shares sold in this offering will be freely tradable without
restriction or further registration under the Securities Act, except that any
shares purchased by our "affiliates," as that term is defined in Rule 144 under
the Securities Act, generally only may be sold in compliance with the
limitations of Rule 144 described below. All of the remaining 21,953,409 shares
of common stock that will be outstanding after this offering will be
"restricted securities" as that term is defined under Rule 144. Restricted
securities may be sold in the public market only if they qualify for an
exemption from registration under Rule 144, including Rule 144(k), or Rule 701
under the Securities Act.

Lock-Up Agreements

    Our directors, executive officers and substantially all of our other
stockholders, holding 21,903,409 shares in the aggregate upon completion of
this offering (including 22,996 shares issued in October 1999 upon the exercise
of outstanding options), have agreed that they will not sell, directly or
indirectly, any shares of common stock without the prior written consent of
BancBoston Robertson Stephens Inc. for a lock-up period of 180 days from the
date of this prospectus. Upon expiration of the lock-up period, 180 days after
the date of this prospectus, 42,334 shares will be available for resale to the
public in accordance with Rule 144, including Rule 144(k), or Rule 701.

Rule 144

    In general, under Rule 144 as currently in effect, commencing 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year is entitled to sell within any three-month
period a number of shares that does not exceed the greater of:

  .   1% of the number of shares of common stock then outstanding, which is
      expected to be approximately 274,534 shares upon completion of this
      offering (including 22,996 shares issued in October 1999 upon the
      exercise of outstanding options); 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, subject to the
      restrictions specified in Rule 144.

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.
Commencing 90 days after the date of this prospectus, 50,000 shares not subject
to a lock-up agreement will be available for resale to the public in accordance
with Rule 144.

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 is entitled to sell such
shares under Rule 144(k) without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144. Therefore,
unless otherwise restricted, Rule 144(k) shares may be sold immediately upon
completion of this offering. Immediately upon completion of this offering, no
outstanding shares may be sold under Rule 144(k).

                                       66
<PAGE>

Rule 701

    In general, under Rule 701 of the Securities Act as currently in effect,
any of our employees, consultants or advisors who purchase shares from us in
connection with a compensatory stock plan or other written agreement are
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.

Stock Options

    As of August 31, 1999, options to purchase a total of 2,639,161 shares of
common stock were outstanding, of which 690,426 were then exercisable. Upon
completion of this offering, we intend to file a registration statement to
register for resale an aggregate of 5,914,216 shares of common stock reserved
or anticipated to be reserved for issuance under our 1998 Equity Incentive
Plan, our 1998 Director Stock Option Plan, our 1999 Stock Option Plan for Non-
Employee Directors and our 1999 Employee Stock Purchase Plan. That registration
statement will become effective immediately upon filing. Accordingly, shares
covered by that registration statement will become eligible for sale in the
public markets, subject to vesting restrictions, Rule 144 volume limitations
applicable to our affiliates or the lock-up agreements with BancBoston
Robertson Stephens Inc. All holders of outstanding options have entered into
lock-up agreements.

    We have agreed not to sell or otherwise dispose of any shares of common
stock during the 180-day period following the date of the prospectus, except we
may issue and grant options to purchase shares of common stock under the 1998
Equity Incentive Plan, the 1998 Director Stock Option Plan, the 1999 Stock
Option Plan for Non-Employee Directors and the 1999 Employee Stock Purchase
Plan. In addition, we may issue shares of common stock in connection with an
acquisition of another company if the terms of such issuance provide that the
common stock so issued shall not be resold prior to the expiration of the 180-
day lock-up period.

Registration Rights

    Upon completion of this offering, under specified circumstances and subject
to customary conditions, the holders of an aggregate of 21,861,075 shares of
our common stock, including CMGI, which will directly own approximately
19,772,360 shares upon completion of this offering, or their permitted
assignees, will be entitled to rights with respect to the registration under
the Securities Act of some or all of their shares, subject to the 180-day lock-
up period described above. Under the agreements providing for these
registration rights, these stockholders are subject to lock-up periods of not
more than 180 days following the date of this prospectus or any subsequent
prospectus. A more detailed discussion of these registration rights is included
in this prospectus under the headings "Certain Transactions--Relationship and
Transactions Between NaviSite and CMGI, Inc.--Investor Rights Agreement" and
"Description of Capital Stock--Registration Rights."

division of First Albany Corporation, have severally agreed with us, subject to

</TABLE>

    The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price on the
cover page of this prospectus and to some dealers at that price less a
concession of not in excess of $    per share, of which $    may be reallowed
to other dealers. After this offering, the public offering price, concession
and reallowance to dealers may be reduced by the representatives. This
reduction will not change the amount of proceeds to be received by us as stated
on the cover page of this prospectus. The common stock is offered by the
underwriters as stated herein, subject to receipt and acceptance by them and
subject to their right to reject any order in whole or in part.

    Over-Allotment Option. We have granted to the underwriters an option,
exercisable during the 30-day period after the date of this prospectus, to
purchase up to 825,000 additional shares of common stock at the same price per
share as we will receive for the 5,500,000 shares that the underwriters have
agreed to purchase. To the extent that the underwriters exercise this option,
each of the underwriters will have a firm commitment to purchase approximately
the same percentage of the additional shares that the number of shares of
common stock to be purchased by it shown in the above table represents as a
percentage of the 5,500,000 shares offered in this offering. If purchased,
these additional shares will be sold by the underwriters on the same terms as
those on which the 5,500,000 shares are being sold. We will be obligated,
pursuant to the option, to sell shares to the extent the option is exercised.
The underwriters may exercise this option only to cover over-allotments made in
connection with the sale of the shares of common stock offered hereby. If this
option is exercised in full, the total price to the public, underwriting
discounts and commissions and proceeds to us will be $   , $    and $   ,
respectively. The underwriting discount and commission per share is equal to
the public offering price per share of common stock less the amount paid by the
underwriters to us per share of common stock.

    NaviSite estimates total expenses payable by us in connection with this
offering, other than the underwriting discounts and commissions referred to
above, will be approximately $1.6 million.

    Indemnity. The underwriting agreement contains covenants of indemnity among
the underwriters and us against various civil liabilities, including
liabilities under the Securities Act and liabilities arising from breaches of
representations and warranties contained in the underwriting agreement.

    Lock-Up Agreements. Each executive officer and director and substantially
all of our stockholders have agreed, during the period of 180 days after the
date of this prospectus, subject to various exceptions, not to offer to sell,
contract to sell, or otherwise sell, dispose of, loan, pledge or grant any
rights with respect to any shares of common stock or any options or warrants to
purchase any shares of common stock, or any securities convertible into or
exchangeable for shares of common stock owned as of the date of this prospectus
or thereafter acquired directly by these holders or with respect to which they
have the power of disposition, without the prior written consent of BancBoston
Robertson Stephens Inc. However, BancBoston Robertson Stephens Inc. may, in its
sole discretion and at any time or from time to time, without notice, release
all or any

                                       68
<PAGE>

portion of securities subject to the lock-up agreements. There are no existing
agreements between the representatives and any of our stockholders who have
executed a lock-up agreement providing consent to the sale of shares prior to
the expiration of the lock-up period.

    In addition, we have agreed that during the lock-up period we will not,
without the prior written consent of BancBoston Robertson Stephens Inc.,
subject to various exceptions:

  .   consent to the disposition of any shares held by stockholders subject
      to lock-up agreements prior to the expiration of the lock-up period; or

  .   issue, sell, contract to sell, or otherwise dispose of, any shares of
      common stock, any options to purchase any shares of common stock or any
      securities convertible into, exercisable for or exchangeable for shares
      of common stock other than our sale of shares in this offering, the
      issuance of our common stock upon the exercise of outstanding options,
      the issuance of options under existing stock option and incentive plans
      provided the options do not vest prior to the expiration of the lock-up
      period and the issuance of our common stock in connection with an
      acquisition of another company if the terms of such issuance provide
      that the common stock so issued shall be subject to the terms of the
      lock-up agreement. Please refer to the information in this prospectus
      under the heading "Shares Eligible for Future Sale."

    The underwriters have advised us that they do not intend to confirm sales
to any accounts over which they exercise discretionary authority.

    Public Offering Price. Prior to this offering, there has been no public
market for the common stock. Consequently, the public offering price for the
common stock offered by this prospectus will be determined through negotiations
among the representatives and us. Among the factors to be considered in such
negotiations, the primary factors are prevailing market conditions, some of our
financial information, market valuations of other companies that we and the
representatives believe to be comparable to us, estimates of our business
potential, the present state of our development and other factors deemed
relevant.

    Directed Share Program. The underwriters have reserved an aggregate of
275,000 shares of common stock to be issued by us and offered for sale in this
offering for purchase from the underwriters through a directed share program by
officers, directors and employees of NaviSite. An additional 275,000 shares of
common stock to be issued by us and offered for sale in this offering have been
reserved for purchase from the underwriters through a directed share program by
vendors, business partners, customers and potential customers of NaviSite. In
addition, the underwriters have reserved an aggregate of 825,000 shares of
common stock to be issued by us and offered for sale in this offering for
purchase from the underwriters through a directed share program by United
States stockholders of CMGI who hold at least 100 shares of CMGI stock as of
August 25, 1999 and who have access to the Internet and a personal e-mail
address. These sales will be at the initial public offering price. We cannot
assure you that any of the reserved shares will be so purchased. The number of
shares of common stock available for sale to the general public in this
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 in this offering.

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

    Participation Rights. Assuming the conversion into common stock of our
preferred stock held by Dell and Microsoft, we have agreed to use all
commercially reasonable efforts to require that the underwriters offer to Dell
and Microsoft in this offering up to an aggregate of 0.5% of the outstanding
shares of our common

                                       69
<PAGE>

stock, calculated on a fully diluted basis, after giving effect to the sale of
shares of common stock in this offering. Because, notwithstanding our

    Stabilization. The representatives have advised us that, pursuant to
Regulation M under the Securities Act, some persons participating in this
offering may engage in transactions, including stabilizing bids, syndicate
covering transactions or the imposition of penalty bids, that may have the
effect of stabilizing or maintaining the market price of the common stock at a
level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of shares of common stock on
behalf of the underwriters for the purpose of fixing or maintaining the price
of the common stock. A "syndicate covering transaction" is the bid for or the
purchase of common stock on behalf of the underwriters to reduce a short
position incurred by the underwriters in connection with this offering. A
"penalty bid" is an arrangement permitting the representatives to reclaim the
selling concession otherwise accruing to an underwriter or syndicate member in
connection with this offering if the common stock originally sold by such
underwriter or syndicate member is purchased by the representatives in a
syndicate covering transaction and has therefore not been effectively placed by
such underwriter or syndicate member. The representatives have advised us that
these transactions may be effected on the Nasdaq National Market or otherwise
and, if commenced, may be discontinued at any time.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
NaviSite, Inc.:

    We have audited the accompanying consolidated balance sheets of NaviSite,
Inc. as of July 31, 1998 and 1999, and the related consolidated statements of
operations, stockholders' equity (deficit), and cash flows for each of the
years in the three-year period ended July 31, 1999. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of NaviSite, Inc. as of July
31, 1998 and 1999, and the results of its operations and its cash flows for
each of the years in the three-year period ended July 31, 1999, in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                          July 31, 1997, 1998 and 1999

(1) Description of Business

    NaviSite, Inc. (the "Company") is a leading provider of business critical
Internet outsourcing solutions, specializing in high-end Web hosting and
application services for companies conducting business on the Internet.
Substantially all revenues are generated from customers in the United States.

(2) Summary of Significant Accounting Policies

 (a) Basis of Presentation

    The Company is a majority owned subsidiary of CMGI, Inc. ("CMGI" or
"Parent"). The Company commenced operations in July 1996 and was incorporated
on February 3, 1997 as CMG Information Technology, Inc. (subsequently renamed
NaviSite Internet Services Corporation). On December 28, 1998, the assets and
liabilities of the Company were contributed to a newly-formed subsidiary,
NaviSite, Inc. The assets and liabilities were recorded at historical amounts
as the entities were under common control. 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 July 1996.

    The consolidated financial statements include certain allocations from CMGI
for certain general and administrative expenses such as rent, legal services,
insurance, and employee benefits. Allocations are based primarily on headcount.
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.

 (b) Principles of Consolidation

    The accompanying financial statements include the accounts of the Company
and its wholly owned subsidiary, Servercast Communications, L.L.C.
("Servercast") after elimination of all significant intercompany balances and
transactions.

 (c) 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.

 (d) Revenue Recognition

    Revenue consists of monthly fees for server hosting, systems
administration, application rentals and Web site management services. Revenue
(other than installation fees) is generally billed and recognized over the term
of the contract, generally one year, based on actual usage. Installation fees
are typically recognized at the time that installation occurs. Payments
received in advance of providing services are deferred until the period such
services are provided.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                          July 31, 1997, 1998 and 1999


 (e) Cash

    Under an arrangement with CMGI, the Company maintained a zero balance cash
account. Cash required by the Company for the funding of its operations was
provided as needed with a corresponding increase to the "Debt to CMGI" account.
Customer receipts and other cash receipts of the Company were remitted to CMGI
upon receipt by the Company and serve to reduce the "Debt to CMGI" account.

    During fiscal 1998, non-cash investing activities included the acquisition
of Servercast (see note 4) in exchange for term notes totaling $1,000,000.

    During fiscal 1999, non-cash financing activities included the issuance of
1,323,953 shares of the Company's Series A Convertible Preferred Stock ("Series
A Preferred Stock") in exchange for 8,000,000 shares of the Company's common
stock and $15,767,600 reduction in debt to CMGI and the issuance of 541,859
shares of the Company's Series B Convertible Preferred Stock ("Series B
Preferred Stock") in exchange for a $14,713,000 reduction in debt to CMGI (see
note 9). Non-cash financing activities also included a software licensing
arrangement, including services and maintenance of $923,000, for an aggregate
of $2.5 million, payable over a three-year period. The Company has recorded
deferred IPO costs of $496,000, which are included in accrued expenses at July
31, 1999.

    The Company purchased $195,000 and $378,000 of equipment under capital
lease obligations during the fiscal years ended July 31, 1998 and 1999,
respectively.

 (f) Software Development Costs

    Software development costs are accounted for under Statement of Financial
Accounting Standard ("SFAS") No. 86, Accounting for Costs of Computer Software
to be Sold, Leased or Otherwise Marketed ("SFAS 86"). Capitalization of
software development costs commences upon the establishment of technological
feasibility. To date, all such amounts have been insignificant, and,
accordingly, the Company has charged all such costs to product development
expense.

 (g) 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 acquired 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.

 (h) Goodwill

    Goodwill relates to the Company's purchase of its wholly owned subsidiary,
Servercast, in July 1998 (see note 4). Such costs are being amortized on a
straight-line basis over five years, the period expected to be benefited.

 (i) 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
ongoing basis, management reviews the value and period of amortization or
depreciation of long-lived assets, including goodwill. During this review, the
significant assumptions used in determining the original cost of long-lived
assets are reevaluated. Although the

                                 NAVISITE, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                          July 31, 1997, 1998 and 1999

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 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.

 (j) 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 for the amounts 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.

 (k) Advertising Costs

    The Company recognizes advertising costs as incurred. The Company did not
incur any advertising costs during fiscal 1997. Advertising expense was
approximately $266,000 and $417,000 for the fiscal years ended July 31, 1998
and 1999, respectively.

 (l) 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 10).

 (m) Historical and Unaudited Pro Forma Basic and Diluted Net Loss per Share

    The Company has adopted SFAS No. 128, Earnings Per Share ("SFAS 128"). In
accordance with SFAS No. 128, basic earnings (loss) per share is computed using
the weighted average number of common shares outstanding during the period.
Diluted earnings (loss) per share is computed using the weighted average number
of common and dilutive common equivalent shares outstanding during the period,
using either the "as-if-converted" method for convertible preferred stock or
the treasury stock method for options, unless such amounts are anti-dilutive.

                          July 31, 1997, 1998 and 1999

    As described in note 9, conversion of all preferred stock and amounts due
to CMGI, if any, outstanding at July 1, 1999, 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 consolidated statements of operations for the fiscal year ended
July 31, 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 "as-if-converted" method.

    The reconciliation of the numerators and denominators of the unaudited pro
forma basic and diluted net loss per share computation for the Company's
reported net loss for the year ended July 31, 1999 is as follows (in thousands,
except per share data):

 (n) Segment Reporting

    The Company has adopted the provisions of SFAS No. 131, Disclosures About
Segments of an Enterprise and Related Information ("SFAS 131"), effective
August 1, 1998. 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. The Company currently operates in only one segment, and as
such, no additional disclosures are required.

 (o) 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 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 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
consolidated financial statements. The Company does not expect its adoption to
have a material impact on its financial position or results of operations.

                          July 31, 1997, 1998 and 1999


    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 year 2001 pursuant to SFAS No. 137 (issued in June 1999),
which delays the adoption of SFAS 133 until that time. The Company expects that
the adoption of SFAS 133 will not have a material impact on the its financial
position or its results of operations.

(4) Acquisition of Servercast Communications, L.L.C.

    In July 1998, the Company acquired Servercast Communications, L.L.C.
("Servercast"), a leading provider of high-performance Internet outsourcing
solutions. The Company issued $1,000,000 in term notes with principal payable
on January 2, 2000. CMGI has guaranteed the payment of these term notes.
Interest accrues at the rate of 5.5% and is payable in three equal installments
on January 2, 1999, July 2, 1999 and January 2, 2000. The total purchase price
for Servercast was valued at $1,045,000, including acquisition costs of
$20,000, and bridge notes receivable of $25,000.

    Total purchase price was allocated as follows (in thousands):

                                                  ======
</TABLE>
    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.
The results of operations of Servercast have been included in the Company's
consolidated financial statements from July 1, 1998.

    The portion of the purchase price allocated to goodwill is being amortized
on a straight-line basis over five years. Amortization of goodwill resulting
from the acquisition of Servercast was approximately $17,000 for the one month
period in the fiscal year ended July 31, 1998 in which Servercast was owned by
the Company and $203,000 for the year ended July 31, 1999.

    The following table represents the unaudited pro forma results of
operations of the Company for the years ended July 31, 1997 and 1998, as if the
Servercast purchase had occurred at the beginning of the respective periods.
These pro forma results include adjustments for the amortization of goodwill
and increased interest expense on debt related to the acquisition. They have
been prepared for comparative purposes only and do not purport to be indicative
of what would have occurred had the acquisition been made at the beginning of
the respective periods or of results that may occur in the future.

(5) Debt to CMGI

    Commencing in February 1998, advances made by CMGI to the Company accrued
interest at the annual rate of 7%. In December 1998, advances of $15,767,600
from CMGI, including accrued interest thereon, were converted into 1,323,953
shares of Series A Preferred Stock. These advances were made by CMGI to the
Company from inception through October 1998. In May 1999, the Company
formalized its borrowing arrangement with CMGI and executed a secured
convertible demand note with CMGI dated as of May 1, 1999 (the "Secured
Convertible Demand Note"). The Secured Convertible Demand Note covers advances
made by CMGI to the Company for periods commencing in November 1998. Under the
Secured Convertible Demand Note, 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 B Preferred Stock. The number of Series B 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 is made. (The conversion price applicable to advances made and
interest accrued during a fiscal quarter in which an offering triggering
automatic conversion into Company common stock of Series B Preferred Stock
occurs is equal to the public offering price per share, and the conversion
price applicable to advances made and interest accrued during a fiscal quarter
in which CMGI elects to connect those advances or that interest prior to the
end of that fiscal quarter is the conversion price in effect for the
immediately preceding fiscal quarter). Effective June 4, 1999, CMGI elected to
convert advances and accrued interest outstanding at May 31, 1999 in the amount
of $14,713,000 into 541,859 shares of Series B Convertible Preferred Stock. See
also Note 9.

    Average balances outstanding in Debt to CMGI for the years ended July 31,
1997, 1998, and 1999 amounted to $965,000, $6,113,000 and $8,107,000,
respectively.

(7) Commitments and Contingencies

  (a) Leases

    CMGI has entered into noncancelable operating leases on behalf of the
Company covering certain of its office facilities and equipment which expire

the Company's headquarters for which it is charged based upon an allocation of
the total costs for the facilities at market rates. Substantially all leases
for real property have been guaranteed by CMGI.

    Total rent expense amounted to $1,722,000, $3,567,000 and $5,983,000 for
the years ended July 31, 1997, 1998 and 1999, respectively.

</TABLE>

    In May 1999, the Company agreed to lease an additional 150,000 square feet
in Andover, Massachusetts over an initial lease term of 12 years. Further, the
Company made a cash payment to the developers of $5.7 million to fund
construction of leasehold improvements and provided a letter of credit for $4.0
million as a construction and lease security deposit and is committed to
provide $2.5 million as an additional security deposit. Also, in May 1999, the
Company agreed to lease a 66,000 square foot facility in San Jose, California
for a lease term of seven years. Further, the Company has made a lease deposit
of $252,000 and provided a letter of credit for $2.4 million as a lease
security deposit to be reduced annually based on the remaining term of the
lease. CMGI has guaranteed both of these leases. CMGI will be released from the
Andover guaranty upon the earlier of the completion of an initial public
offering or the date on which the Company occupies the premises and begins to
pay rent. CMGI will be released from the San Jose guaranty within 15 days of
the later of the closing of this offering and the execution by the Company of a
letter of credit in the amount of approximately $2.4 million.

    The Company is currently finalizing construction contracts in connection
with its new facilities in San Jose, California and Andover, Massachusetts. If
the Company executes either or both of these contracts prior to the completion
of the initial public offering, CMGI will be required to execute a guarantee on
the Company's behalf with respect to each executed contract. Each contract
provides that CMGI will be released from any related guarantee upon completion
of the initial public offering. In connection with the construction contract
for the new Andover, Massachusetts facility, the Company will be required, upon
CMGI's release from its guarantee or, if the contract is executed after the
completion of the initial public offering, upon execution of the contract, to
obtain a letter of credit in the amount of the remaining balance due under the
contract, which is currently estimated to be less than $15 million.

  (b) Litigation

    The Company is subject to legal proceedings and claims which arise in the
ordinary course of its business. In the opinion of management, the amount of
ultimate liability with respect to these actions will not materially affect the
consolidated financial position or results from operations of the Company.

(8) 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 July 31,
1999, the Company had no federal net operating loss carryforwards available to
offset future taxable income as the Company's parent, CMGI, has utilized
substantially all of the Company's federal net operating losses through July
31, 1999. The Company has recorded a full valuation allowance against its
deferred tax assets since management believes that, after considering all the
available objective evidence, both positive and negative, historical and
prospective, with greater weight given to historical evidence, it is more
likely than not that these assets will not be realized. No income tax benefit
has been recorded for all periods presented because of the valuation allowance.

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

shares of Series A Preferred Stock in exchange for 8,000,000 shares of common
stock and $15,767,600 in principal amount of Debt to CMGI. The Series A

 (b) Series B Preferred Stock

    In May 1999, the Board of Directors approved the designation of 1,000,000
shares of the Company's preferred stock as Series B Preferred Stock. Effective

outstanding under the Secured Convertible Demand Note as of January 31, 1999,
April 30 and May 31, 1999, in the aggregate amount of $14,713,000 into 541,859
shares of Series B Preferred Stock. The conversion of advances and accrued
interest into Series B Preferred Stock was based on the estimated fair value of
the Company as of the end of each of the fiscal quarters in which such advances
were made, except with respect to the advances converted as of June 4, 1999,
prior to the end of the fiscal quarter. Under the terms of the Secured
Convertible Demand Note, advances converted prior to the end of the fiscal
quarter in which they were made are converted based upon the conversion price
in effect for the immediately preceding fiscal quarter. Based on an enterprise
valuation determined through a discounted cash flow analysis for the fiscal
quarter ended January 31, 1999, $5,347,705 of advances and accrued interest
were converted at a per share price of $12.74 into 419,738 shares of Series B
Preferred Stock. Based on an enterprise valuation determined through arms'
length negotiations with, and subsequent sales of Series C Preferred Stock and
Series D Preferred Stock to, two unaffiliated third parties on June 4, 1999, a
per share valuation of $76.68 was utilized to convert $5,413,117 and $3,952,110
of advances and accrued interest into 70,594 and 51,527 shares of Series B
Preferred Stock, respectively.

    The Series B Preferred Stock is entitled to received noncumulative annual
dividends at 7%, as and if declared. No dividends have been declared or paid by
the Company. The Series B Preferred Stock is fully participating, voting and
convertible into 10 shares of common stock, subject to certain adjustments. In
the event of any liquidation, dissolution or winding up of the Company, the
Series B Preferred Stock ranks pari passu with the Series A Preferred Stock,
and has a liquidation preference equal to its purchase price plus dividends
computed at 7% per annum. The Series B Preferred Stock is convertible into
common stock immediately at the option of the holder and automatically converts
into common stock upon the completion of a qualifying initial public offering.

    At July 31, 1999, 5,418,590 shares of common stock have been reserved for
issuance upon the conversion of the Series B Preferred Stock. See also Note 14.

certain adjustments. In the event of any liquidation, dissolution or winding up
of the Company, the Series C Preferred Stock ranks pari passu with the Series A
and B Preferred Stock and has a liquidation preference equal to its purchase
price plus dividends computed at 7% per annum. The Series C Preferred Stock

(10) Stock Option Plans

 (a) NaviSite 1998 Equity Incentive Plan

    In December 1998, the Company's Board of Directors and Stockholders
approved the 1998 Equity Incentive Plan, as amended (the "1998 Plan"). The 1998
plan replaced NaviSite Internet Services Corporation's 1997 Equity Incentive
Plan (the "1997 Plan"). All options outstanding under the 1997 Plan were
cancelled and replaced with an equivalent amount of options issued in
accordance with the 1998 Plan. Under the 1998 Plan, non-qualified stock options
or incentive stock options may be granted to the Company's or its affiliates'
employees, directors and consultants, as defined, up to a maximum number of
shares of common stock not to exceed 2,500,000 shares. In August 1999, the
Board of Directors approved an increase in the number of shares authorized
under the 1998 Plan to 5,562,212. The Board of Directors administers this plan,
selects the individuals to whom options will be granted and determines the
number of shares and exercise price of each option. Options are granted at
estimated fair market value based on third-party valuations or cash equity
transactions with unrelated parties (when available). Options granted under the
1998 Plan have a five-year maximum term and typically vest over a four year
period, with 25% of options granted becoming exercisable one year from the date
of grant and the remaining 75% vesting monthly for the next thirty-six (36)
months. The following table reflects activity and historical exercise prices of
stock options under the Company's 1998 Plan for the three years ended July 31,
1999.

the date of his or her election, a non-statutory option to purchase common
stock as defined. A maximum number of 125,000 shares of common stock are
authorized for issuance under the 1998 Director Plan. Each automatic grant will
have an exercise price equal to the current fair market value of the common
stock at the time of grant and will have a maximum term of ten years, subject
to earlier termination following the optionee's cessation of service on the
board of directors. Each automatic option grant shall vest and become
exercisable with respect to 20% of the options granted on the first anniversary
of the date of the grant, and shall become exercisable with respect to an
additional 20% on the date of each annual stockholders' meeting at which the
option-holder is re-elected as director.

    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 the stock-based compensation plans in which the
Company's employees participate. Had compensation cost for awards in fiscal
1997, 1998 and 1999 under the three stock-based compensation plans in which the
Company's employees participate been determined based on the fair value method
set forth under SFAS 123, the pro forma effect on the Company's net loss would
have been as follows:

                          July 31, 1997, 1998 and 1999


The pro forma per share net loss reflects the fair-value compensation cost
associated with option grants to the Company's employees under the 1986 Plan.

    The fair value of each stock option grant has been estimated on the date of
grant using the Black-Scholes option pricing model with the following weighted
average assumptions for fiscal 1997, 1998 and 1999, respectively: volatility of
59.00%, 75.50% and 100%; risk-free interest rate of 6.19%, 5.48% and 5.16%;
4-year expected life of options for all years; and 0% dividend yield for all
years. The weighted average fair value per share of options granted during
fiscal 1997, 1998 and 1999 was $0.01, $0.21 and $3.08, respectively.

    The fair value of each stock option granted under the 1986 Plan has been
estimated on the date of grant using the Black-Scholes option pricing model
with the following weighted average assumptions for fiscal 1997, 1998 and 1999,
respectively: volatility of 66.69%, 90.07% and 100%; risk-free interest rate of
6.19%, 5.50% and 5.16%; expected life of options of 6.2, 4.2 years and 4.3
years; and 0% dividend yield for all years. The weighted average fair value per
share of options granted during fiscal 1997, 1998 and 1999 was $1.30, $1.58 and
$31.58, respectively.

(11) Comprehensive Income

    The Company adopted SFAS No. 130, Reporting Comprehensive Income (SFAS
130). This statement requires that all components of comprehensive income be
reported in the financial statements in the period in which they are
recognized. For each year reported, comprehensive loss under SFAS 130 was
equivalent to the Company's net loss reported in the accompanying consolidated
statements of operations.

(12) Related Party Transactions

    CMGI has provided the Company with accounting, 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 for CMGI's
corporate headquarters through an allocation based upon the company's headcount
located on the premises 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. CMGI also
has provided the Company with Internet marketing and business development
services. Amounts due CMGI are included in "Debt to CMGI" on the consolidated
balance sheets. The following table summarizes the expenses allocated to the
Company by CMGI for enterprise services, rent and facilities, human resources
and benefits and Internet marketing and business development:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                          July 31, 1997, 1998 and 1999


    The Company sells its products and services to companies in which CMGI has
an investment interest or a significant ownership interest. Total revenue
realized from services to related parties was $3,361,000, $3,871,000 and
$7,058,000 for the fiscal years ended July 31, 1997, 1998 and 1999,
respectively. These related parties typically receive a 10% discount for
services provided by the Company. The related cost of revenue is consistent
with the costs incurred on similar transactions with unrelated parties.

    The Company provides administrative services related to the leasing of
equipment on behalf of CMGI and related entities. These services include the
negotiation of lease terms and conditions and payment of lessors' monthly lease
charges. CMGI or the related entity is then charged the actual lease fees.
Under this arrangement, CMGI bears all liability for payment, and NaviSite is
not financially obligated under the leases.

(13) Concentration of Credit Risk

    Amounts included in the consolidated balance sheets for accounts
receivable, debt to CMGI, accounts payable, accrued expenses and notes payable
approximate their fair value due to their short maturities. Financial
instruments that potentially subject the Company to concentration of credit
risk consist primarily of trade receivables. 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 an allowance for potential credit losses and such
losses have been within management's expectations.

    For the year ended July 31, 1997, all of the Company's revenue was earned
from related parties. Three of these related parties accounted for 46%, 28% and
14% of revenue earned during the year ended July 31, 1997. For the fiscal year
ended July 31, 1998, 96% ($3,871,000) of the Company's revenue was earned from
related parties. Three of these related parties accounted for 40%, 19% and 11%
of revenue earned for the fiscal year ended July 31, 1998. For the fiscal year
ended July 31, 1999, 67% ($7,058,000) of the Company's revenue was earned from
related parties. Two of these related parties accounted for 22% and 16% of
revenue earned during the fiscal year ended July 31, 1999.

    Accounts receivable at July 31, 1998 included 63% due from related parties,
with two related entities comprising 37% and 15%. Accounts receivable at July
31, 1999 included 30% due from related parties, with one related entity
comprising 13%.

(14) Subsequent Events

 (a) 1999 Employee Stock Purchase Plan

    The 1999 Employee Stock Purchase Plan (the "Stock Purchase Plan") was
adopted by the Company's Board of Directors and Stockholders in October 1999.
The Stock Purchase Plan provides for the issuance of a maximum of 50,000 shares
of the Company's common stock.


 (b) Deferred Compensation Plan

    A Deferred Compensation Plan (the "Deferred Compensation Plan") was adopted
by the Company's Board of Directors in October 1999. Under the terms of the
Deferred Compensation Plan, the Company's employees who are selected by the
Board of Directors (as well as certain of the Company's employees who
previously participated in a deferred compensation plan sponsored by CMGI) will
be able to elect to defer a portion of their compensation for the following
calendar year. The Company also may make discretionary contributions to a
participant's account, to which the participant generally will become entitled
after five years of service with the Company.

 (c) 1999 Director Stock Option Plan

    In October 1999, the Company terminated the 1998 Director Plan and the
Board of Directors and the Stockholders approved and adopted the 1999 Stock
Option Plan for Non-Employee Directors (the "1999 Director Plan"). A total of
250,000 shares of common stock are reserved for issuance under the 1999
Director Plan. Directors who are not NaviSite employees or otherwise
affiliates, employees or designees of an institutional or corporate investor
that owns more than 5% of outstanding common stock will be eligible to receive
non-statutory stock options under the 1999 Director Plan. Under the 1999
Director Plan, the Company will grant an initial option to acquire 25,000
shares of common stock to each eligible director who is elected a director for
the first time.






    The Company also will grant to eligible directors an additional option for
the purchase of 6,250 shares of common stock on the first, and each subsequent,
anniversary of the grant of each director's initial option if the director is
still serving as one of the Company's directors on that anniversary date. The
Board of Directors has discretion to increase to up to 100,000 shares the
number of shares of common stock subject to any initial option or additional
option covering any vesting period of up to 48 months that may be granted to an
eligible director after the date of the increase.

 (d) Series B Preferred Stock

    Immediately prior to the completion of the initial public offering, CMGI
will convert intercompany debt in the aggregate amount of approximately
$12,257,000, representing funds advanced subsequent to the quarter ended July
31, 1999, into 111,424 shares of Series B Preferred Stock (based upon a
conversion price of $110, assuming an initial public offering price of $11.00
per share). The Company does not expect to borrow funds from CMGI after the
completion of the initial public offering.

                         NOTES TO FINANCIAL STATEMENTS

                      December 31, 1997 and June 30, 1998

(1) Organization

    Servercast Communications, L.L.C., ("Servercast" or the "Company") was
organized on February 6, 1997 as a Delaware limited liability company. The
Company's operating agreement indicates that Servercast will cease to operate
no later than December 1, 2050. Profits and losses are allocated to members in
accordance with the proportionate percentage interest as determined by the fair
market value of their original capital contribution. As a limited liability
company, the members' liability is limited to the amounts of their investment
in the Company.

    The Company provides Web site hosting and maintenance for a variety of
companies engaging in electronic commerce. Servercast also develops Web sites.
Servercast's customers are located throughout the United States.

(2) Summary of Significant Accounting Policies

 (a) Revenue Recognition

    Revenue for hosting and maintaining Web sites is recognized ratably over
the life of the contract, typically one year. Revenue from the development of
Web sites is recognized as the services are performed.

 (b) Cash Equivalents

    For purposes of the statement of cash flows, Servercast considers all
highly liquid debt instruments with an original maturity of three months or
less to be cash equivalents.

 (c) Property and Equipment

    Property and equipment are stated at cost. Depreciation and amortization
are provided for on the straight-line basis over the estimated useful lives of
the related assets. The depreciation period is generally three to seven years.

 (d) Income Taxes

    The Company is treated as a partnership for federal and state tax purposes
and thus is not subject to income taxes. The members of the Company must
include their proportionate share of the Company's profits and losses in their
respective personal tax returns. Accordingly, no provision has been made for
income taxes.

    For income tax purposes, the Company has elected to report under the
accrual basis of accounting. At December 31, 1997 and June 30, 1998, the tax
bases of the Company's assets and liabilities are $8,167 and $9,092 less,
respectively, than the financial reporting bases of these assets and
liabilities. The difference results from the use of different methods related
to reporting depreciation, and the Company's allowance for doubtful accounts
which is not deductible until the accounts are written-off.

 (e) Long-Lived Asset Impairment

    The Company adopted Statement of Financial Accounting Standards No. 121,
Accounting for the Impairment of Long-Lived Assets to be Disposed Of ("SFAS No.
121"). SFAS No. 121 addresses the accounting for the impairment of long-lived
assets, certain identifiable intangible assets and goodwill when events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. The Company adoption of SFAS No. 121 had no material impact on
its results of operations or financial condition.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                      December 31, 1997 and June 30, 1998


 (f) Fair Value of Financial Instruments

    The Company adopted Statement of Financial Accounting Standards No. 107,
"Disclosures About Fair Value of Financial Statements" ("SFAS No. 107"), which
requires that the Company estimate and disclose the fair value of each material
class of financial instrument for which it is practicable to estimate that
value. In accordance with SFAS No. 107, the Company has identified its material
financial instruments as cash, trade receivables and payables and notes
payable. The carrying amount of cash, trade receivables, trade payables and
notes payable approximate fair value because of the short-term nature of these
financial instruments.

 (g) Concentration of Credit Risk

    Financial instruments which subject the Company to credit risk consist
principally of trade receivables. The Company's policy with respect to the
credit risk of trade receivables is to evaluate, prior to the extension of
credit, each customer's financial condition and to determine the amount of open
credit to be extended.

 (h) Management's Estimates

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount 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.

 (i) Comprehensive Income

    On January 1, 1998, the Company adopted the provisions of Statement of
Financial Accounting Standards No. 131, "Reporting Comprehensive Income" ("SFAS
No. 131"). SFAS No. 131 requires that the components of comprehensive income be
reported in the financial statements. For the period from inception (February
6, 1997) through December 31, 1997 and for the six months ended June 30, 1998,
the Company's net loss was equal to its total comprehensive loss.

(3) Commitments

    The Company leases certain office facilities under operating leases with an
initial term of less than one year. Additionally, the Company leases certain
floor space at facilities that house its equipment used for Web site hosting.
The lessors of these locations provide the Company with Web hosting and
maintenance services for the benefit of the Company's customers. These
agreements also have initial terms of one year or less.

    For the period from inception (February 6, 1997) through December 31, 1997
and for the six months ended June 30, 1998, rent and Web hosting expenses under
these agreements amounted to $102,117 and $68,901, respectively. Of these
amounts, $64,352 and $47,769 were included in cost of revenues in the
accompanying statements of operations, respectively. For the period from
inception (February 6, 1997) through December 31, 1997 and for the six months
ended June 30, 1998, $33,305 and $12,175 of the rents included in selling,
general and administrative expenses were paid to a related party who is a
member of the Company. Subsequent to the sale of the Company on July 1, 1998
(see note 6), the Company relocated its Web hosting equipment to sites
maintained by the purchaser, and, accordingly, the Company no longer leases
these Web hosting sites from unrelated third parties.

                      December 31, 1997 and June 30, 1998


(4) Note Payable

    At June 30, 1998, note payable represented a $25,000 note payable, due upon
demand, to NaviSite Internet Services, Inc. ("NaviSite") (see note 6). The note
is secured by substantially all assets of the Company and bears interest at a
rate of 5.50% per annum.

(5) Major Customers

    At December 31, 1997, three customers accounted for 31%, 34% and 26% of
accounts receivable, respectively. Revenue earned from these customers for the
period from inception (February 6, 1997) through December 31, 1997 amounted to
36%, 22% and 12%, respectively, of total revenue during the period.

    At June 30, 1998, three customers accounted for 30%, 20% and 18% of
accounts receivable, respectively. Revenue earned from these customers for the
six months ended June 30, 1998 amounted to 28%, 5% and 6% of total revenue
during the period.

(6) Subsequent Event

    Effective July 1, 1998, NaviSite purchased the outstanding membership
interests of all members in exchange for a $1,000,000 note payable. The
acquisition will be recorded using the purchase method of accounting.

             UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL DATA

    The unaudited pro forma combined condensed statement of operations of the
Company for the year ended July 31, 1998 gives pro forma effect to the July 1,
1998 acquisition of Servercast Communications, L.L.C. ("Servercast") as if it
had occurred on 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 Servercast for the period from August 1, 1997 through June 30,
1998 (the results of operations of Servercast for the period July 1, 1998
through July 31, 1998 are included in the consolidated statement of operations
of the Company).

    The Company has accounted for the acquisition under the purchase method of
accounting. The total cost of the acquired business of $1,045,000, including
direct acquisition costs, has been allocated to the underlying tangible and
intangible assets acquired and liabilities assumed based on their respective
fair values, resulting in goodwill of $1,014,000.

    The unaudited pro forma financial data are not necessarily indicative of
the results of operations of the Company had the transaction occurred on August
1, 1997, 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 should be read in conjunction with the consolidated financial
statements and notes thereto included elsewhere in this prospectus.

Item 14. Indemnification of Directors and Officers.

    The Delaware General Corporation Law and our revised certificate of
incorporation provide for indemnification of our officers and directors for
liabilities and expenses that they may incur in such capacities.

    Our revised certificate of incorporation generally provides that we shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit, investigation,
administrative hearing or any other proceeding by reason of the fact that he or
she is or was a director or officer of ours, or is or was serving at our
request as a director, officer, employee or agent of another entity, against
expenses incurred by him or her in connection with such proceeding. An officer
or director shall not be entitled to indemnification by us if:

  .   the officer or director did not act in good faith and in a manner
      reasonably believed to be in, or not opposed to, our best interests;
      or

  .   with respect to any criminal action or proceeding, the officer or
      director had reasonable cause to believe his conduct was unlawful.

    Our revised certificate of incorporation limits the liability of our
directors to the maximum extent permitted by Delaware law. Section 145 of the
Delaware General Corporation Law provides that directors will not be personally
liable for monetary damages for breach of their fiduciary duties as directors,
except liability for:

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

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

  . unlawful payments of dividends or unlawful stock repurchases or
  redemptions; or

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

    This provision has no effect on any non-monetary remedies that may be
available to us or our stockholders, nor does it relieve us or our officers or
directors from compliance with federal or state securities laws.

                                      II-1

    The underwriting agreement provides that the underwriters are obligated,
under certain circumstances, to indemnify directors, officers and controlling
persons of NaviSite against some liabilities, including liabilities under the
Securities Act. Reference is made to the form of underwriting agreement filed
as Exhibit 1.1 hereto.

    Our officers and directors are currently insured under a policy procured by
CMGI that provides coverage against losses arising from claims against them for
any actual or alleged act, omission, misstatement, misleading statement,
neglect, error or breach of duty by them in their capacity as officers or
directors of NaviSite. We also have obtained our own liability insurance for
our officers and directors effective as of September 20, 1999. At the present
time, there is no pending litigation or proceeding involving any director,
officer, employee or agent of NaviSite in which indemnification will be
required or permitted. We are not aware of any threatened litigation or
proceeding that may result in a claim for such indemnification.

Item 15. Recent Sales of Unregistered Securities.

    In the three fiscal years preceding the filing of this registration
statement, NaviSite has issued the following securities that were not
registered under the Securities Act:

    (a) Issuance of Capital Stock.

    In December 1998, NaviSite issued 60,589 shares of common stock and
1,323,953 shares of Series A convertible preferred stock to NaviSite Internet
Services Corporation, our predecessor and a wholly owned subsidiary of CMGI,
Inc., in exchange for a contribution of assets from NaviSite Internet Services
Corporation. In April 1999, NaviSite issued an additional 8,749 shares of
common stock to NaviSite Internet Services Corporation. Upon the merger of
NaviSite Internet Services Corporation with and into CMGI, which was effective
as of October 1, 1999, the 69,338 shares of common stock held of record by
NaviSite Internet Services Corporation were exchanged for outstanding shares of
NaviSite Internet Services Corporation which were issued to NaviSite employees
pursuant to option exercises under the 1997 NaviSite Internet Services
Corporation Equity Incentive Plan. The 1998 NaviSite, Inc. Equity Incentive
Plan replaces the 1997 NaviSite Internet Services Corporation Equity Incentive
Plan. Upon the merger of NaviSite Internet Services Corporation with and into
CMGI, all of the outstanding options granted under the 1997 Equity Incentive
Plan were cancelled and replaced with an equivalent amount of options issued in
accordance with our 1998 Equity Incentive Plan.

    The 1,323,953 shares of Series A convertible preferred stock were
distributed to CMGI upon consummation of the merger. Every one share of Series
A convertible preferred stock will convert into 10 shares of common stock upon
completion of this offering.

    In June 1999, NaviSite issued 541,859 shares of its Series B convertible
preferred stock to CMGI in exchange for cancellation of an aggregate of
$14,712,932 of intercompany debt pursuant to a secured convertible demand note
to CMGI dated May 1, 1999. It is expected that every one share of Series B
convertible preferred stock will convert into 10 shares of common stock upon
completion of this offering.

    In June 1999, pursuant to the Series C Preferred Stock Purchase Agreement
between NaviSite and Dell USA L.P., NaviSite issued 1,095,472 shares of Series
C convertible preferred stock to Dell at a purchase price of $7.40 per share or
$8,106,493, in the aggregate. It is expected that upon completion of this
offering, the 1,095,472 shares of Series C convertible preferred stock will
convert into 1,095,472 shares of common stock.

    In June 1999, pursuant to the Series D Convertible Preferred Stock Purchase
Agreement between NaviSite and Microsoft Corporation, NaviSite issued 993,243
shares of its Series D convertible preferred stock to Microsoft, at a purchase
price of $7.40 per share or $7,350,000, in the aggregate. It is expected that
upon completion of this offering, the 993,243 shares of Series D convertible
preferred stock will convert into 993,243 shares of common stock.

    In October 1999, options were exercised for an aggregate of 22,996 shares
of common stock, for an aggregate consideration of $14,651.50.

                                      II-2

    (b) Grants of Stock Options.

    In December 1998, the NaviSite, Inc. 1998 Equity Incentive Plan replaced
the 1997 NaviSite Internet Services Corporation Equity Incentive Plan. As noted
in Item 15(a) above, as part of the corporate reorganization of NaviSite
Internet Services Corporation, all options outstanding under the 1997 NaviSite
Internet Services Corporation Equity Incentive Plan were cancelled and replaced
with an equivalent amount of options issued in accordance with our 1998 Equity
Incentive Plan upon the merger of NaviSite Internet Services Corporation with
and into CMGI. As of September 30, 1999, we had granted options to purchase an
aggregate of 2,564,161 shares of common stock under the 1998 Equity Incentive
Plan (which number includes options granted in replacement of options granted
by NaviSite Internet Services Corporation under the 1997 NaviSite Internet
Services Corporation Equity Incentive Plan), exercisable at a weighted average
exercise price of $3.03 per share.

    On December 28, 1998, we granted options to purchase 50,000 shares of
common stock under our 1998 Director Stock Option Plan exercisable at $0.34 per
share.

    On August 18, 1999, we granted options to purchase 25,000 shares of common
stock under our 1998 Director Stock Option Plan at an exercise price per share
equal to the per share public offering price set forth on the cover page of
this prospectus.

    No underwriters were involved in the foregoing sales of securities. These
sales were made in reliance upon an exemption from the registration provisions
of the Securities Act set forth in Section 4(2) thereof relative to sales by an
issuer not involving any public offering or the rules and regulations
thereunder or, in the case of options to purchase common stock, Rule 701 under
the Securities Act. All of the foregoing securities are deemed restricted
securities for purposes of the Securities Act.

Item 17. Undertakings.

    The undersigned Registrant hereby undertakes 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.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, 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) that for the purposes of determining any liability under the
      Securities Act of 1933, the information omitted from the form of
      prospectus filed as part of this registration statement in reliance
      upon Rule 430A and contained in a form of prospectus filed by the
      Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the
      Securities Act shall be deemed to be part of this registration
      statement as of the time it was declared effective.

  (2) that for the purpose of determining any liability under the Securities
      Act of 1933, each post-effective amendment that contains a form of
      prospectus shall be deemed to be a new registration statement relating
      to the securities offered therein, and the offering of such securities
      at that time shall be deemed to be the initial bona fide offering
      thereof.

1.   ARTICLE 1 GENERAL PROVISIONS

          1.1  BASIC DEFINITIONS

               1.1.1  THE CONTRACT DOCUMENTS

The Contract Documents consist of the Agreement between Owner and Contractor
(hereinafter the Agreement), Conditions of the Contract (General, Supplementary
and other Conditions), Drawings, Specifications, Addenda issued prior to
execution of the Contract, other documents listed in the Agreement and
modifications issued after execution of the Contract. A Modification is (1) a
written amendment to the Contract signed by both parties, (2) a Change Order,
(3) a Construction Change Directive or (4) a written order for a minor change in
the Work issued by the Architect. Unless specifically enumerated in the
Agreement, the Contract Documents do not include other documents such as bidding
requirements (advertisement or invitation to bid, Instructions to Bidders,
sample forms, the Contractor's bid or portions of Addenda relating to bidding
requirements).

               1.1.2  THE CONTRACT

The Contract Documents form the Contract for Construction. The Contract
represents the entire and integrated agreement between the parties hereto and
supersedes prior negotiations, representations or agreements, either written or
oral. The Contract may be amended or modified only by a Modification. The
Contract Documents shall not be construed to create a contractual relationship
of any kind (1) [TEXT DELETED] (2) between the Owner and a Subcontractor or Sub-
subcontractor, (3) between the Owner and Architect or (4) between any persons or
entities other than the Owner and Contractor. [TEXT DELETED].

               1.1.3  THE WORK

The term "Work" means the construction and services required by the Contract
Documents, whether completed or partially completed, and includes all other
labor, materials, equipment and services provided or to be provided by the
Contractor to fulfill the Contractor's obligations. The Work may constitute the
whole or a part of the Project.
<PAGE>

               1.1.4  THE PROJECT

The Project is the total construction of which the Work performed under the
Contract Documents may be the whole or a part and which may include construction
by the Owner or by separate contractors.

               1.1.5  THE DRAWINGS

The Drawings are the graphic and pictorial portions of the Contract Documents
showing the design, location and dimensions of the Work, generally including
plans, elevations, sections, details, schedules and diagrams.

               1.1.6  THE SPECIFICATIONS

The Specifications are that portion of the Contract Documents consisting of the
written requirements for materials, equipment, systems, standards and
workmanship for the Work, and performance of related services.

               1.1.7  THE PROJECT MANUAL

The Project Manual is a volume assembled for the Work which may include the
bidding requirements, sample forms, Conditions of the Contract and
Specifications.

          1.2  CORRELATION AND INTENT OF THE CONTRACT DOCUMENTS

               1.2.1  The intent of the Contract Documents is to include all
items necessary for the proper execution and completion of the Work by the
Contractor. The Contract Documents are complementary, and what is required by
one shall be as binding as if required by all; performance by the Contractor
shall be required only to the extent consistent with the Contract Documents and
reasonably inerrable from them as being necessary to produce the indicated
results.

               1.2.2  Organization of the Specifications into divisions,
sections and articles, and arrangement of Drawings shall not control the
Contractor in dividing the Work among Subcontractors or in establishing the
extent of Work to be performed by any trade.
<PAGE>

               1.2.3  Unless otherwise stated in the Contract Documents, words
which have well-known technical or construction industry meanings are used in
the Contract Documents in accordance with such recognized meanings.

          1.3  CAPITALIZATION

               1.3.1  Terms capitalized in these General Conditions include
those which are (1) specifically defined, (1) specifically defined, (2) the
titles of numbered articles and identified references to Paragraphs,
subparagraphs and Clauses in the document or (3) the titles of other document
published by the American Institute Architects.

          1.4  INTERPRETATION

               1.4.1  In the interest of brevity the Contract Documents
frequently omit modifying words such as "all" and "any" and articles such as
"the" and "an," but the fact that a modifier or an article is absent from one
statement and appears in another is not intended to affect the interpretation of
either statement.

          1.5  EXECUTION OF CONTRACT DOCUMENTS

               1.5.1  The contract Documents shall be signed by the Owner and
Contractor. [TEXT DELETED]

               1.5.2  Execution of the Contract by the Contractor is a
representation that the Contractor has visited the site, become generally
familiar with local conditions under which the Work is to be performed and
correlated personal observations with requirements of the Contract Documents.

          1.6  OWNERSHIP AND USE OF DRAWINGS, SPECIFICATIONS AND OTHER
INSTRUMENTS OF SERVICE

the property on which the Project is located, usually referred to as the site,
and the owner's interest therein.

          2.2  INFORMATION AND SERVICES REQUIRED OF THE OWNER

               2.2.1  The Owner shall, at the written request of the contractor,
prior to commencement of the Work and thereafter, furnish to the Contractor
reasonable evidence that financial arrangements have been made to fulfill the
Owner's obligations under the Contract. Furnishing of such evidence shall be a
condition precedent to commencement or continuation of the Work. After such
evidence has been furnished, the Owner shall not materially vary such financial
arrangements without prior notice to the Contractor.

               2.2.2  [TEXT DELETED]

               2.2.3  [TEXT DELETED]
<PAGE>

               2.2.4  Information or services required of the Owner by the
Contract Documents shall be furnished by the Owner with reasonable promptness.

          2.3  OWNER'S RIGHT TO STOP THE WORK

               2.3.1  If the Contractor fails to correct Work which is not in
accordance with the requirements of the Contract Documents as required by
Paragraph 12.2 or persistently fails to carry out Work in accordance with the
Contract Documents, the Owner may issue a written order to the Contractor to
stop the Work, or any portion thereof, until the cause for such order has been
eliminated; however, the right of the Owner to stop the Work shall not give rise
to a duty on the part of the Owner to exercise this right for the benefit of the
Contractor or any other person or entity, except to the extent required by
Subparagraph 6.1.3.

          2.4  OWNER'S RIGHT TO CARRY OUT THE WORK

               2.4.1  If the Contractor defaults or neglects to carry out the
Work in accordance with the Contract Documents and fails within a seven-day
period after receipt of written notice from the Owner to commence and continue
correction of such default or neglect with diligence and promptness, the Owner
may after such seven-day period give the Contractor a second written notice to
correct such deficiencies with a three-day period. If the Contractor within such
three-day period after receipt of such second notice fails to commence and
continue to correct any deficiencies, the Owner may, without prejudice to other
remedies the Owner may have, correct such deficiencies. In such case an
appropriate. Change Order shall be issued deducting from payments then or
thereafter due the Contractor the reasonable cost of correcting such
deficiencies, including Owner's expenses and compensation for the Architect'
additional services made necessary by such default, neglect or failure. [TEXT
DELETED] If payments then or thereafter due the contractor are not
<PAGE>

sufficient to cover such amounts, the Contractor shall pay the difference to the
Owner.

3.   ARTICLE 3 CONTRACTOR

          3.1  GENERAL

               3.1.1  The Contractor is the person or entity identified as such
in the Agreement and is referred to throughout the Contract Documents as if
singular in number. The term "contractor" means the Contractor or the
contractor's authorized representative.

               3.1.2  The Contractor shall perform the Work in accordance with
the Contract Documents.

               3.1.3  The Contractor shall not be relieved of obligations to

portion of the Work, as well as the information furnished by the Owner pursuant
to Subparagraph 2.2.3, shall take field measurements of any existing conditions
related to that portion of the Work and shall observe any conditions at the site
affecting it. These obligations are for the purpose of facilitating construction
by the Contractor and are not for the purpose of discovering errors, omissions,
or inconsistencies in the Contract Documents; however, any errors
inconsistencies or omissions discovered by the Contractor shall be reported
promptly to the [TEXT DELETED] Owner. [TEXT DELETED]
<PAGE>

               3.2.2  Any design errors or omissions noted by the Contractor
during this review shall be reported promptly to the [TEXT DELETED] Owner, but

means, methods, techniques, sequences or procedures. If the Contractor
determines that such means, methods, techniques, sequences or procedures may not
be safe, the Contractor shall give timely written notice to the Owner [TEXT
DELETED] and shall not proceed with that portion of the Work without further
written instructions from the [TEXT DELETED] Owner. If the Contractor is then
instructed to proceed with the required means, methods, techniques, sequences or
procedures without acceptance of changes proposed by the Contractor, the Owner
shall be solely responsible for any resulting loss or damage.

               3.3.2  The Contractor shall be responsible to the owner for acts
and omissions of the Contractor's employees, Subcontractors and their agents and
employees, and other persons or entities performing portions of the Work for or

portions of Work already performed to determine that such portions are in proper
conditions to receive subsequent Work.
<PAGE>

          3.4  LABOR AND MATERIALS

consent of the owner, [TEXT DELETED] and in accordance with a Change Order.

               3.4.3  The Contractor shall enforce strict discipline and good
order among the Contractors employees and other persons carrying out the

bear such professional's written approval when submitted to the [TEXT DELETED]
Owner. The Owner [TEXT DELETED] shall be entitled to rely upon the adequacy,
accuracy and completeness of the services, certifications or approvals performed
by such design professionals, provided the Owner [TEXT DELETED] have specified
to the Contractor all performance and design criteria that such services must
satisfy. Pursuant to this Subparagraph 3.12.10, the [TEXT DELETED] Owner will

Claims shall rest with the party making the Claim.

               4.3.2  Time Limits on Claims. Claims by either party must be

been reasonably anticipated and had an adverse effect on the scheduled
construction.

               4.3.8  Injury or Damage to Person or Property. If either party to

party to investigate the matter.

               4.3.9  If unit prices are stated in the Contract Documents or
subsequently agreed upon, and if quantities originally contemplated are
materially changed in a proposed Change Order or Construction Change Directive
so that application of such unit prices to quantities of Work proposed will

               4.6.1  [TEXT DELETED]

               4.6.2  Claims not resolved by mediation shall be decided by
arbitration which, unless the parties mutually agree otherwise, shall be in
accordance with the Construction Industry Arbitration Rules of the American
Arbitration Association currently in effect. The demand for arbitration shall be
filed in writing with the other party to the Contract and with the American
Arbitration Association. [TEXT DELETED]

               4.6.3  A demand for arbitration shall be made within the time
limits specified in Subparagraphs 4.4.6 and 4.6.1 as applicable, and in other
cases within a reasonable time after the Claim has arisen, and in no event shall
it be made after the date when institution of legal or equitable proceedings
based on such Claim would be barred by the applicable statute of limitations as
determined pursuant to Paragraph 13.7.

               4.6.4  Limitation on Consolidation or Joinder. [TEXT DELETED]. No
arbitration shall include, by consolidation or joinder or in any other manner,
parties other than the Owner, Contractor, a separate contractor as described in
Article 6 and other persons substantially involved in a common question of fact
or law whose presence is required if complete relief is to be accorded in
arbitration. No person or entity other than the Owner, Contractor or a separate
contractor as described in Article 6 shall be included as an original third
party or additional third party to an arbitration whose interest or
responsibility is insubstantial. Consent to arbitration involving an additional
person or entity shall not constitute consent to arbitration of a Claim not
described therein or with a person or entity not named or described therein. The
foregoing agreement to arbitrate and other agreements to arbitrate with an
additional person or entity duly consented to by parties to the
<PAGE>

Agreement shall be specifically enforceable under applicable law in any court
having jurisdiction thereof.

5.   SUBCONTRACTORS

          5.1  DEFINITIONS

               5.1.1  A Subcontractor is a person or entity who has a direct
contract with the Contractor to perform a portion of the work at the site. The
term "Subcontractor" is referred to throughout the Contract Documents as if
singular in number and means a Subcontractor or an authorized representative of
the Subcontractor. The term "Subcontractor" does not include a separate
contractor or subcontractors of a separate contractor.

               5.1.2  A Sub-subcontractor is a person or entity who has a direct
or indirect contract with a Subcontractor to perform a portion of the Work at
the site. The term "Sub-subcontractor" is referred to throughout the Contract
Documents as if singular in number and means a Sub-subcontractor or an
authorized representative of the Sub-subcontractor.

          5.2  AWARD OF SUBCONTRACTS AND OTHER CONTRACTS FOR PORTIONS OF THE
WORK

               5.2.1  [TEXT DELETED]. The Contractor, as soon as practicable
after award of the Contract, shall furnish in writing to the Owner [TEXT
DELETED] the names of persons or entities (including those who are to furnish
materials or equipment fabricated to a special design) proposed for each
principal
<PAGE>

portion of the Work. The [TEXT DELETED] Owner will promptly reply to the
Contractor in writing stating whether or not the Owner [TEXT DELETED], after due
investigation, has reasonable objection to any such proposed person or entity.
[TEXT DELETED]

               5.2.2  The Contractor shall not contract with a proposed person
or entity to whom the Owner [TEXT DELETED] has made reasonable and timely
objection. The Contractor shall not be required to contract with anyone to whom
the Contractor has made reasonable objection.


               5.2.3  If the Owner [TEXT DELETED ] has reasonable objection to a
person or entity proposed by the Contractor, the Contractor shall propose
another to whom the Owner [TEXT DELETED] has no reasonable objection. If the
proposed but rejected Subcontractor was reasonably capable of performing the
Work, the Contract Sum and Contract Time shall be increased or decreased by the
difference, if any, occasioned by such change, and an appropriate Change Order
shall be issued before commencement of the substitute Subcontractor's work.
However, no increase in the Contract Sum or Contract Time shall be allowed for
such change unless the Contractor has acted promptly and responsively in
submitting names as required.

          5.3  SUBCONTRACTUAL RELATIONS

               5.3.1  By appropriate written agreement, [TEXT DELETED] the
Contractor shall require each Subcontractor, to the extent of the Work to be
performed by the Subcontractor, to be bound to the Contractor by terms of the
Contract Documents, and to assume toward the Contractor all the obligations and
responsibilities, including the responsibility for safety of the Subcontractor's
Work, which the Contractor, by these Documents, assumes toward the Owner [TEXT
DELETED]. Each subcontract agreement shall preserve and protect the rights of
the Owner [TEXT DELETED] under the Contract Documents with respect to the Work
to be performed by the Subcontractor so that subcontracting thereof will not
prejudice such rights, and shall allow to the Subcontractor, unless specifically
provided otherwise in the subcontract agreement, the benefit of all rights,
remedies and redress against the Contractor that the Contractor, by the Contract
Documents, has against
<PAGE>

the Owner. Where appropriate, the Contractor shall require each Subcontractor to
enter into similar agreements with Sub-subcontractors. The Contractor shall make
available to each proposed Subcontractor, prior to the execution of the
subcontract agreement, copies of the Contract Documents to which the
Subcontractor will be bound, and, upon written request of the Subcontractor,
identify to the Subcontractor terms and conditions of the proposed subcontract
agreement which may be at variance with the Contract Documents. Subcontractors
will similarly make copies of applicable portions of such documents available to
their respective proposed Sub-subcontractors.


          5.4  CONTINGENT ASSIGNMENT OF  SUBCONTRACTS

                5.4.1 Each subcontract agreement for a portion of the Work is
assigned by the Contractor to the Owner provided that:

                      5.4.1.1  assignment is effective only after termination of
the Contract by the Owner for cause pursuant to Paragraph 14.2 and only for
those subcontract agreements which the Owner accepts by notifying the
Subcontractor and Contractor in writing; and

                      5.4.1.2  assignment is subject to the prior rights of the
surety, if any, obligated under bond relating to the Contract.

               5.4.2  Upon such assignment, if the Work has been suspended for
more than 30 days, the Subcontractor's compensation shall be equitably adjusted
for increases in cost resulting from the suspension.


6.   CONSTRUCTION BY OWNER OR BY SEPARATE CONTRACTORS


          6.1  OWNER'S RIGHT TO PERFORM CONSTRUCTION AND TO AWARD SEPARATE
CONTRACTS

               6.1.1  The Owner reserves the right to perform construction or
operations related to the Project with the Owner's own forces, and to award
separate contracts in connection with other portions of the Project or other
construction or
<PAGE>

operations on the site under Conditions of the Contract identical or
substantially similar to these including those portions related to insurance and
waiver of subrogation. If the Contractor claims that delay or additional cost is
involved because of such action by the Owner, the Contractor shall make such
Claim as provided in Paragraph 4.3.

               6.1.2  When separate contracts are awarded for different portions
of the Project or other construction or operations on the site, the term
"Contractor" in the Contract Documents in each case shall mean the Contractor
who executes each separate Owner-Contractor Agreement.

               6.1.3  [TEXT DELETED]. The Contractor shall make any revisions to
the construction schedule deemed necessary after a joint review and mutual
agreement. The construction schedules shall then constitute the schedules to be
used by the Contractor, separate contractors and the Other until subsequently
revised.

               6.1.4  Unless otherwise provided in the Contract Documents, when
the Owner performs construction or operations related to the Project and the
Owner's own forces, the Owner shall be deemed to be subject to the same
obligations and to have the same rights which apply to the Contractor under the
Conditions of the Contract, including, without excluding others, those stated in
Article 3, this Article 6 and Articles 10, 11 and 12.

          6.2  MUTUAL RESPONSIBILITY

               6.2.1  The Contractor shall afford the Owner and separate

required by the Contract documents.

               6.2.2  If part of the Contractor's Work depends for proper
execution or results upon construction or operations by the Owner or a separate
contractor, the Contractor shall, prior to proceeding with that portion of the
Work,
<PAGE>

promptly report to the [TEXT DELETED] apparent discrepancies or defects in such
other construction that would render it unsuitable for such proper execution and
results. Failure of the contractor so to report shall constitute an
acknowledgment that the Owner's or separate contractor's completed or partially
completed construction is fit and proper to receive the Contractor's Work,
except as to defects not then reasonably discoverable.

               6.2.3  The Owner shall be reimbursed by the Contractor for costs
incurred by the Owner which are payable to a separate contractor because of
delays, improperly timed activities or defective construction of the Contractor.

Contractor because of delays, improperly timed activities, damage to the Work or
defective construction of a separate contractor.

          6.3  OWNER'S RIGHT TO CLEAN UP

               6.3.1  If a dispute arises among the Contractor, separate
contractors and the Owner as to the responsibility under their respective
contracts for maintaining the premises and surrounding area free from waste
materials and rubbish, the Owner may clean up and [TEXT DELETED] allocate the
cost among those responsible.

7.   CHANGES IN THE WORK

          7.1  GENERAL

<PAGE>

               7.1.1  Changes in the Work may be accomplished after execution of
the Contract, and without invalidating the Contract, by Change Order,
Construction Change Directive or order for a minor change in the Work, subject
to the limitations stated in this Article 7 and elsewhere in the Contract
Documents.

               7.1.2  A Change Order shall be based upon agreement among the
Owner, and Contractor [TEXT DELETED] a Construction Change Directive requires
agreement by the Owner [TEXT DELETED] and may or may not be agreed to by the
Contractor; an order for a minor change in the Work may be issued by the [TEXT
DELETED] Owner alone.

               7.1.3  Changes in the Work shall be performed under applicable
provisions of the Contract Documents, and the Contractor shall proceed promptly,
unless otherwise provided in the Change Order, Construction Change Directive or
order for a minor change in the Work.

          7.2  CHANGE ORDERS

               7.2.1  [TEXT DELETED]

               7.2.2  Methods used in determining adjustments to the Contract
Sum may include those listed in Subparagraph 7.3.3.

          7.3  CONSTRUCTION CHANGE DIRECTIVES

               7.3.1  A Construction Change Directive is a written order [TEXT
DELETED] signed by the Owner [TEXT DELETED], directing a change in the Work
prior to the agreement on adjustment, if any, in the Contract sum or Contract
Time, or both. The Owner may by Construction Change Directive, without
invalidating the Contract, order changes in the Work within the general scope of
the Contract consisting of additions, deletions or other revisions, the Contract
Sum and Contract Time being adjusted accordingly.

               7.3.2  A Construction Change Directive shall be used in the
absence of total agreement on the terms of a Change Order.
<PAGE>

               7.3.3  If the Construction Change Directive provides for an
adjustment to the Contract Sum, the adjustment shall be based on one of the
following methods:

          .1   mutual acceptance of a lump sum properly itemized and supported
               by sufficient substantiating data to permit evaluation;

          .2   unit prices stated in the Contract Documents or subsequently
               agreed upon

          .3   cost to be determined in a manner agreed upon by the parties and
               a mutually acceptable fixed or percentage fee; or

          .4   as provided in Subparagraph 7.3.6.

               7.3.4  Upon receipt of a Construction Change Directive, the
Contractor shall promptly proceed with the change in the Work involved and
advise the [TEXT DELETED] Owner of the Contractor's agreement or disagreement
with the method, if any, provided in the Construction Change Directive for
determining the proposed adjustment in the Contract Sum or Contract Time.

               7.3.5  A Construction Change Directive signed by the Contractor
indicates the agreement of the Contractor therewith, including adjustment in
Contract Sum and Contract Time or the method for determining them. Such
agreement shall be effective immediately and shall be recorded as a Change
Order.

               7.3.6  If the Contractor does not respond promptly or disagrees
with the method for adjustment in the Contract Sum, the method and the
adjustment shall be determined by the Architect on the basis of reasonable
expenditures and savings of those performing the Work attributable to the
change, including, in the case of an increase in the Contract Sum, a reasonable
allowance for overhead and profit. In such case, and also under Clause 7.3.3.3,
the Contractor shall keep and present, in such form as the Architect may
prescribe, an itemized accounting together with appropriate supporting data.
Unless otherwise provided in the Contract Docu-
<PAGE>

ments, costs for the purposes of this Subparagraph 7.3.6 shall be limited to the
following:

          .1   costs of labor, including social security, old age and
               unemployment insurance, fringe benefits required by agreement or
               custom, and workers' compensation insurance;

          .2   costs of materials, supplies and equipment, including cost of
               transportation, whether incorporated or consumed;

          .3   rental costs of machinery and equipment, exclusive of hand tools,
               whether rented from the Contractor or others;

          .4   costs of premiums for all bonds and insurance, permit fees, and
               sales, use of similar taxes related to the Work; and

          .5   additional costs of supervision and field office personnel
               directly attributable to the change.

               7.3.7  The amount of credit to be allowed by the Contractor to
the Owner for a deletion or change which results in a net decrease in the
Contract Sum shall be actual net cost [TEXT DELETED]. When both additions and
credits covering related Work or substitutions are involved in a change, the
allowance for overhead and profit shall be figured on the basis of net increase,
if any, with respect to that change.

               7.3.8  Pending final determination of the total cost of a
Construction Change Directive to the Owner, amounts not in dispute for such
changes in the Work shall be included in Applications for Payment accompanied by
a Change Order indicating the parties' agreement with part or all of such costs.
[TEXT  DELETED]


               7.3.9   When the Owner and Contractor agree with [TEXT DELETED]
the adjustments in the Contract Sum and Contract Time, or otherwise reach
agreement upon the adjustments, such agreement shall be effective immedi-
<PAGE>

ately and shall be recorded by preparation and execution of an appropriate
Change Order.

8.   TIME

          8.1  DEFINITIONS

               8.1.2  The date of commencement of the Work is the date
established in the Agreement.

               8.1.3  [TEXT DELETED]

               8.1.4  The term "day" as used in the Contract Documents shall
mean calendar day unless otherwise specifically defined.

          8.2  PROGRESS AND COMPLETION

               8.2.1  Time limits stated in the Contract Documents are of the
essence of the Contract. By executing the Agreement the Contractor confirms that
the Contract Time is a reasonable period for performing the Work.

               8.2.2  The Contractor shall not knowingly, except by agreement or
instruction of the Owner in writing, prematurely commence operations on the site
or elsewhere prior to the effective date of insurance required by Article 11 to
be furnished by the Contractor and Owner. The date of commencement of the Work
shall not be changed by the effective date of such insurance. Unless the date of
<PAGE>

commencement is established by the Contract Documents or a notice to proceed
given by the Owner, the Contractor shall notify the Owner in writing not less
than five days or other agreed period before commencing the Work to permit the
timely filing of mortgages, mechanic's liens and other security interests.

               8.2.3  The Contractor shall proceed expeditiously with adequate
forces and shall achieve Substantial Completion within the Contract Time.

          8.3  DELAYS AND EXTENSIONS OF TIME

               8.3.1  If the Contractor is delayed at any time in the
commencement or progress of the Work by an act or neglect of the Owner, [TEXT

by the Owner, or by changes ordered in the Work, or by labor disputes, fires,
unusual delay in deliveries, unavoidable casualties or other causes beyond the
Contractor's control, and are not reasonably foreseeable [TEXT DELETED] then the
Contract Time shall be extended by the Change Order for such reasonable time as
the [TEXT DELETED] Owner and Contractor may mutually determine.

               8.3.2  Claims relating to time shall be made in accordance with
applicable provisions of Paragraph 4.3.

               8.3.3  This Paragraph 8.3 does not preclude recovery of damages
for delay by either party under other provisions of the Contract Documents.

               9.2.1  Before the first Application for Payment, the Contractor
shall submit to the [TEXT DELETED] Owner a schedule of values allocated to
various portions of the Work, prepared in such form and supported by such data

basis for reviewing the Contractor's Applications for Payment.

          9.3  APPLICATIONS FOR PAYMENT

               9.3.1  At least ten days before the date established for each
progress payment, the Contractor shall submit to the [TEXT DELETED] Owner an

DELETED] but not yet included in Change Orders.

                      9.3.1.2  Such applications may not include requests for

and shall include the costs of applicable insurance, storage and transportation
to the site for such materials and equipment stored off the site.

               9.6.2  The Contractor shall promptly pay each Subcontractor, upon
receipt of payment from the Owner, out of the amount paid to the Contractor on
account of such Subcontractor's portion of the Work, the amount to which said
Subcontractor is entitled, reflecting percentages actually retained from the
payments to the Contractor on account of such Subcontractor's portion of the
Work. The Contractor shall, by appropriate agreement with each Subcontractor,
require each Subcontractor to make payments to Sub-subcontractors in a similar
manner.

               9.6.3  [TEXT DELETED]

               9.6.4  [TEXT DELETED] The Owner [TEXT DELETED] shall not have an
obligation to pay or to see to the payment of money to a Subcontractor except as
may otherwise be required by law.

               9.6.5  Payment to material suppliers shall be treated in a manner
similar to that provided in Subparagraphs 9.6.2, 9.6.3 and 9.6.4.
<PAGE>

               9.6.6  [TEXT DELETED] A progress payment, or partial or entire
use or occupancy of the Project by the Owner shall not constitute acceptance of
Work not in accordance with the Contract Documents.

               9.6.7  Unless the Contractor provides the Owner with a payment
bond in the full penal sum of the Contract Sum, payments received by the
Contractor for Work properly performed by Subcontractors and suppliers shall be
held by the Contractor for those Subcontractors or suppliers who performed Work
or furnished materials, or both, under contract with the Contractor for which
payment was made by the Owner. Nothing contained herein shall require money to
be placed in a separate account and not commingled with money of the Contractor,
shall create any fiduciary liability or tort liability on the part of the
Contractor for breach of trust or shall entitle any person or entity to an award
of punitive damages against the Contractor for breach of the requirements of
this provision.

               9.7.1  [TEXT DELETED]

          9.8  SUBSTANTIAL COMPLETION

               9.8.1  [TEXT DELETED]

               9.8.2  When the Contractor considers that the Work, or a portion
thereof which the Owner agrees to accept separately, is substantially complete,
the Contractor shall prepare and submit to the Owner [TEXT DELETED] a
comprehensive list of items to be completed or corrected prior to final payment.
Failure to include an item on such list does not alter the responsibility of the
Contractor to complete all Work in accordance with the Contract Documents.

               9.8.3  Upon receipt of the Contractor's list, the [TEXT DELETED]
Owner will make an inspection to determine whether the Work or designated
portion thereof is substantially complete. If the [TEXT DELETED] Owner's
inspection discloses any item, whether or not included on the Contractor's list,
which is not sufficiently complete in accordance with the Contract Documents so
that the
<PAGE>

Owner can occupy or utilize the Work or designated portion thereof for its
intended use, the Contractor shall, before insurance of the Certificate of
Substantial Completion, complete or correct such item upon notification by the
[TEXT DELETED] Owner. In such case, the Contractor shall then submit a request
for another inspection by the [TEXT DELETED] Owner to determine Substantial
Completion.

               9.8.4  When the Work or designated portion thereof is
substantially complete, the [TEXT DELETED] Owner will prepare a Certificate of
Substantial Completion which shall establish the date of Substantial Completion,
shall establish responsibilities of the Owner and Contractor for security,
maintenance, heat, utilities, damage to the Work and insurance, and shall fix
the time within which the Contractor shall finish all items on the list
accompanying the Certificate. Warranties required by the Contract Documents
shall commence on the date of Substantial Completion of the Work or designated
portion thereof, unless otherwise provided in the Certificate of Substantial
Completion.

               9.8.5  The Certificate of Substantial Completion shall be
submitted to the [TEXT DELETED] Contractor for [TEXT DELETED] its written
acceptance of responsibilities assigned to them in such Certificate. Upon such
acceptance and consent of surety, if any Upon Substantial Completion of the Work
, the Owner shall make payment of retainage applying to such Work or designated
portion thereof. such payment shall be adjusted for Work that is incomplete or
not in accordance with the requirements of the Contract Documents.

          9.9  PARTIAL OCCUPANCY OR USE

               9.9.1  The Owner may occupy or use any completed or partially
completed portion of the Work at any stage when such portion is designated by
separate agreement with the Contractor, provided such occupancy or use is
consented to by the insurer as required under Clause 11.4.1.5 and authorized by
public authorities having jurisdiction over the Work. Such partial occupancy or
use may commence whether or not the portion is substantially complete, provided
the Owner and Contractor have accepted in writing the responsibilities assigned
to each of them for payments, retainage, if any, security, maintenance, heat,
utilities, damage to the Work and insurance, and have agreed in writing
concerning the period for correction
<PAGE>

of the Work and commencement of warranties required by the Contract Documents.
When the Contractor considers a portion substantially complete, the Contractor
shall prepare and submit a list to the [TEXT DELETED] Owner [TEXT DELETED].
Consent of the Contractor to partial occupancy or use shall not be unreasonably
withheld. The stage of the progress of the Work shall be determined by written
agreement between the Owner and Contractor. [TEXT DELETED]

               9.9.2  Immediately prior to such partial occupancy or use, the
own, and Contractor [TEXT DELETED] shall jointly inspect the area to be occupied
or portion of the Work to be used in order to determine and record the condition
of the Work.

               9.9.3  Unless otherwise agreed upon, partial occupancy or use of
a portion or portions of the Work shall not constitute acceptance of Work not
complying with the requirements of the Contract Documents.

          9.10 FINAL COMPLETION AND FINAL PAYMENT

               9.10.1 [TEXT DELETED]

               9.10.2 neither final payment nor any remaining retained
percentage shall become due until the Contractor submits to the [TEXT DELETED]
Owner (1) an affidavit that payrolls, bills for materials and equipment, and
other indebtedness connected with the Work for which the Owner or the Owner's
property might be responsible or encumbered (less amounts withheld by Owner)
have been paid or otherwise satisfied, (2) a certificate evidencing that
insurance required by the Contract Documents to remain in force after final
payment is currently in effect and will not be canceled or allowed to expire
until at lease 30 days' prior written notice has been given to the Owner, (3) a
written statement that the Contractor knows of no substantial reason that the
insurance will not be renewable to cover the period required by the Contract
Documents, (4) consent of surety, if any, to final payment and (5), if required
by the Owner, other data establishing payment or satisfaction of obligations,
such as receipts, releases and waivers of liens, claims, security interests or
encumbrances arising out of the Contract, to the extent and in such form as may
be designated by the Owner. If a Subcontractor refuses to furnish a release or
waiver
<PAGE>

required by the Owner, the Contractor may furnish a bond satisfactory to the
Owner to indemnify the Owner against such lien. If such lien remains unsatisfied
after payments are made, the Contractor shall refund to the Owner all money that
the Owner may be compelled to pay in discharging such lien, including all costs
and reasonable attorneys' fees.

               9.10.3  If, after Substantial Completion of the Work, final
completion thereof is materially delayed through no fault of the Contractor or
by issuance of Change Orders affecting final completion, [TEXT DELETED] the
Owner shall, upon application by the Contractor [TEXT DELETED], and without
terminating the Contract, make payment of the balance due for that portion of
the Work fully completed and accepted. If the remaining balance for Work not
fully completed or corrected is less than retainage stipulated in the Contract
Documents, and if bonds have been furnished, the written consent of surety to
payment of the balance due for that portion of the Work fully completed and
accepted shall be submitted by the [TEXT DELETED] Contractor to the [TEXT
DELETED] Owner prior to [DELETE- certification of] such payment. Such payment
shall be made under terms and conditions governing final payment, except that it
shall not constitute a waiver of claims.

               9.10.4  The making of final payment shall constitute a waiver of
Claims by the Owner except those arising from:

          .1   liens, Claims, security interests or encumbrances arising out of
               the Contract and unsettled;

          .2   failure of the Work to comply with the requirements of the
               Contract Documents; or

          .3   terms of special warranties required by the Contract Documents.
<PAGE>

          .4   Acceptance of final payment by the Contractor, a Subcontractor or
               material supplier shall constitute a waiver of claims by that
               payee except those previously made in writing and identified by
               that payee as unsettled at the time of final Application for
               Payment.

Owner from claims set forth below which may arise out of or result from the
Contractor's operations under the Contract and for which the Contractor may be

<PAGE>

               11.1.2  The insurance required by Subparagraph 11.1.1 shall be
written for not less than limits of liability specified in the Contract
Documents or required by law, whichever coverage is greater. Coverages, whether
written on an occurrence or claims-made basis, shall be maintained without

               11.3.1  Optionally, the Owner may require the Contractor to
purchase and maintain Project Management Protective Liability insurance from the
Contractor's usual sources as primary coverage for the Owner's, Contractor's and
Architect's vicarious liability for construction operations under the Contract.
Unless otherwise required by the Contract Documents, the Owner shall reimburse
the Contractor by increasing the Contract Sum to pay the cost of purchasing and
maintaining such optional insurance coverage, and the Contractor shall not be
responsible
<PAGE>

for purchasing any other liability insurance on behalf of the Owner.
The minimum limits of liability purchased with such coverage shall be equal to
the aggregate of the limits required for Contractor's Liability Insurance under
Clauses 11.1.1.2 through 11.1.1.5.

               11.3.2  To the extent damages are covered by Project management
Protective Liability insurance, the Owner, Contractor and Architect waive all
rights against each other for damages, except such rights as they may have to
the proceeds of such insurance. The policy shall provide for such waivers of
subrogation by endorsement or otherwise.

               11.3.3  The Owner shall not require the Contractor to include the
Owner, Architect or other persons or entities as additional insureds on the
Contractor's Liability Insurance coverage under Paragraph 11.1.

          11.4 PROPERTY INSURANCE

               11.4.1  Unless otherwise provided, the Owner shall purchase and
maintain, in a company or companies lawfully authorized to do business in the
jurisdiction in which the Project is located, property insurance written on a
builder's risk "all-risk" or equivalent policy form in the amount of the initial
Contract Sum, plus value of subsequent Contract modifications and cost of
materials supplied or installed by others, comprising total value for the entire
Project at the site on a replacement cost basis without optical deductibles.
Such property insurance shall be maintained, unless otherwise provided in the
Contract Documents or otherwise agreed in writing by all persons and entities
who are beneficiaries of such insurance, until final payment has been made as
provided in Paragraph 9.10 or until no person or entity other than the Owner has
an insurable interest in the property required by this Paragraph 11.4 to be
covered, whichever is later. This insurance shall include interests of the
Owner, the Contractor, Subcontractors, and Sub-subcontractors in the Project.

                       11.4.1.1  Property insurance shall be on an "all-risk" or
equivalent policy form and shall include, without limitation, insurance against
the perils of fire (with extended coverage) and physical loss or damage

<PAGE>

without duplication of coverage, theft, vandalism, malicious mischief, collapse,
earthquake, flood, windstorm, falsework, testing and startup, temporary
buildings and debris removal including demolition occasioned by enforcement of
any applicable legal requirements, and shall cover reasonable compensation for
Architect's and Contractor's services and expenses required as a result of such
insured loss.

                      11.4.1.2  If the Owner does not intend to purchase such
property insurance required by the Contract and with all of the coverages in the
amount described above, the Owner shall so inform the Contractor in writing
prior to commencement of the Work. The Contractor may then effect insurance
which will protect the interests of the contractor, Subcontractors and Sub-
subcontractors in the Work, and by appropriate Change Order the cost thereof
shall be charged to the Owner. If the Contractor is damaged by the failure or
neglect of the Owner to purchase or maintain insurance as described above,
without so notifying the Contractor in writing, then the Owner shall bear all
reasonable costs properly attributable thereto.

                      11.4.1.3  If the property insurance requires deductibles,
the Owner shall pay costs not covered because of such deductibles.

                      11.4.1.4  This property insurance shall cover portions of
the Work stored off the site, and also portions of the Work in transit.

                      11.4.1.5  Partial occupancy or use in accordance with
Paragraph 9.9 shall not commence until the insurance company or companies
providing property insurance have consented to such partial occupancy or use by
endorsement or otherwise. The Owner and the Contractor shall take reasonable
steps to obtain consent of the insurance company or companies and shall, without
mutual written consent, take no action with respect to partial occupancy or use
that would cause cancellation, lapse or reduction of insurance.

               11.4.2  Boiler and Machinery Insurance. The Owner shall purchase
and maintain boiler and machinery insurance required by the Contract Document or
by law, which shall specifically cover such insured objects during installation
and until final acceptance by the Owner, this insurance shall include
<PAGE>

interests of the Owner, Contractor, Subcontractors and Sub-subcontractors in the
Work, and the Owner and Contractor shall be named insureds.

               11.4.3  Loss of Insurance. The Owner, at the Owner's option, may
purchase and maintain such insurance as will insure the Owner against loss of
use of the Owner's property due to fire or other hazards, however caused. The
Owner waives all rights of action against the Contractor for loss of use of the
Owner's property, including consequential losses due to fire or other hazards
however caused.

               11.4.4  If the Contractor requests in writing that insurance for
risks other than those described herein or other special causes of loss be
included in the property insurance policy, the Owner shall, if possible, include
such insurance, and the cost thereof shall be charged to the Contractor by
appropriate Change Order.

               11.4.5  If during the Project construction period the Owner
insures properties, real or personal or both, at or adjacent to the site by
property insurance under policies separate from those insuring the Project, or
if after final payment property insurance is to be provided on the completed
Project through a policy or policies other than those insuring the Project
during the construction period, the Owner shall waive all rights in accordance
with the terms of Subparagraph 11.4.7 for damages caused by fire or other causes
of loss covered by this separate property insurance. All separate policies shall
provide this waiver of subrogation by endorsement or otherwise.

               11.4.6  Before an exposure to loss may occur, the Owner shall
file with the Contractor a copy of each policy that includes insurance coverages
required by this Paragraph 11.4. Each policy shall contain all generally
applicable conditions, definitions, exclusions and endorsements related to this
Project. Each policy shall contain a provision that the policy will not be
canceled or allowed to expire, and that its limits will not be reduced, until at
least 30 days' prior written notice has been given to the Contractor.

               11.4.7  Waivers of Subrogation. The Owner and Contractor waive
all rights against (1) each other and any of their subcontractors, sub-subcon-
<PAGE>

tractors, agents and employees, each of the other, and (2) the Architect,
Architect's consultants, separate contractors described in Article 6, if any,
and any of their subcontractors, sub-subcontractors, agents and employees, for
damages caused by fire or other causes of loss to the extent covered by property
insurance obtained pursuant to this Paragraph 11.4 or other property insurance
applicable to the Work, except such rights as they have to proceeds of such
insurance held by the Owner as fiduciary. The Owner or Contractor, as
appropriate, shall required of the Architect, Architect's consultants, separate
contractors described in Article 6, if any, and the subcontractors, sub-
subcontractors, agents and employees of any of them, by appropriate agreements,
written where legally required for validity, similar waivers each in favor of
other parties enumerated herein. the policies shall provide such waivers of
subrogation by endorsement or otherwise. A waiver of subrogation shall be
effective as to a person or entity even though that person or entity would
otherwise have a duty of indemnification, contractual or otherwise, did not pay
the insurance premium directly or indirectly, and whether or not the person or
entity had an insurable interest in the property damaged.

               11.4.8  A loss insured under Owner's property insurance shall be
adjusted by the Owner as fiduciary and made payable to the Owner as fiduciary
for the insureds, as their interests may appear, subject to requirements of any
applicable mortgagee clause and of Subparagraph 11.4.10. The Contractor shall
pay Subcontractors their just shares of insurance proceeds received by the
Contractor, and by appropriate agreements, written where legally required for
validity, shall require Subcontractors to make payments to their Sub-
subcontractors in similar manner.

               11.4.9  If required in writing by a party in interest, the Owner
as fiduciary shall, upon occurrence of an insured loss, give bond for proper
performance of the Owner's duties. The cost of required bonds shall be charged
against proceeds received as fiduciary. The Owner shall deposit in a separate
account proceeds so received, which the Owner shall distribute in accordance
with such agreement as the parties in interest may reach, or in accordance with
an arbitration award in which case the procedure shall be as provided in
Paragraph 4.6. If after such loss not other special agreement is made and unless
the Owner terminates the Contract for conve-
<PAGE>

nience, replacement of damaged property shall be performed by the Contractor
after notification of a Change in the Work in accordance with Article 7.

               11.4.10 The Owner as fiduciary shall have power to adjust and
settle a loss with insurers unless one of the parties in interest shall object
in writing within five days after occurrence of loss to the Owner's exercise of
this power, if such objection is made, the dispute shall be resolved as provided
in Paragraphs 4.5 and 4.6. The Owner as fiduciary shall, in the case of
arbitration, make settlement with insurers in accordance with directions of the
arbitrators. If distribution of insurance proceeds by arbitration is required,
the arbitrators will direct such distribution.

          11.5 PERFORMANCE BOND AND PAYMENT BOND

               11.5.1  The Owner shall have the right to require the Contractor
to furnish bonds covering faithful performance of the Contract and payment of

specifically required in the Contract Documents on the date of execution of the
Contract.

               11.5.2  Upon the request of any person or entity appearing to be
a potential beneficiary of bonds covering payment of obligations arising under
the Contract, the Contractor shall promptly furnish a copy of the bonds or shall
permit a copy to be made.

12.  UNCOVERING AND CORRECTION OF WORK

          12.1 UNCOVERING OF WORK

               12.1.1  If a portion of the Work is covered contrary to the [TEXT
DELETED] requirements specifically expressed in the Contract Documents, it must,
if required in writing by the [TEXT DELETED] requirements specifically expressed
in the Contract Documents, it must, if required in writing by the [TEXT DELETED]
Owner be uncovered for the [TEXT DELETED] Owner's examination and be replaced at
the Contractor's expense without change in the Contract Time.
<PAGE>

               12.1.2  If a portion of the Work has been covered with the [TEXT
DELETED] Owner has not specifically requested to examine prior to its being
covered, the [TEXT DELETED] Owner may request to see such Work and it shall be
uncovered by the Contractor. If such Work is in accordance with the Contract
Documents, costs of uncovering and replacement shall, by appropriate Change
Order, be at the Owner's expense. if such Work is not in accordance with the
Contract Documents, correction shall be at the Contractor's expense unless the
condition was caused by the Owner or a separate contractor in which event the
Owner shall be responsible for payment of such costs.

          12.2 CORRECTION OF WORK

               12.2.1  BEFORE OR AFTER SUBSTANTIAL COMPLETION

                       12.2.1.1  The Contractor shall promptly correct Work
reject by the [TEXT DELETED] Owner or failing to conform to the requirements of
the contract Documents, whether discovered before or after Substantial
Completion and whether or not fabricated, installed or completed. Costs of
correcting such rejected Work, including additional testing and inspections and
[TEXT DELETED] expenses made necessary thereby, shall be at the Contractor's
expense.

               12.2.2  AFTER SUBSTANTIAL COMPLETION

                       12.2.2.1  In addition to the contractor's obligations
under Paragraph 3.5, if, within one year after the date of Substantial
Completion of the Work or designated portion thereof or after the date for
commencement of warranties established under Subparagraph 9.9.1, or by terms of
an applicable special warranty required by the Contract Documents, any of the
Work is found to be not in accordance with the requirements of the Contract
Documents, the Contractor shall correct it promptly after receipt of written
notice from the Owner to do so unless the Owner has previously given the
Contractor a written acceptance of such condition. The Owner shall give such
notice promptly after discovery of the condition. During the one-year period for
correction of Work, if the Owner fails to notify the contractor and give the
Contractor an opportunity to make the correction, the Owner waives the rights to
require correction by the Contractor and to make a claim for breach of
<PAGE>

warranty. If the Contractor fails to correct nonconforming Work within a
reasonable time during that period after receipt of notice from the Owner [TEXT
DELETED], the Owner may correct it in accordance with Paragraph 2.4.

                      12.2.2.2   The one-year period for correction of Work
shall be extended with respect to portions of Work first performed after
Substantial Completion by the period of time between Substantial Completion and

               12.2.3  The Contractor shall remove from the site portions of the
Work which are not in accordance with the requirements of the Contract Documents
and are neither corrected by the Contractor nor accepted by the Owner.

               12.2.4  The Contractor shall bear the cost of correcting
destroyed or damaged construction, whether completed or partially completed, of
the Owner or separate contractors caused by the Contractor's correction or
removal of Work which is not in accordance with the requirements of the Contract
Documents.

               12.2.5  Nothing contained in this Paragraph 12.2 shall be
construed to establish a period of limitation with respect to other obligations
which the contractor might have under the Contract Documents. Establishment of
the one-year period for correction of Work as described in Subparagraph 12.2.2
relates only to the specific obligation of the contractor to correct the Work,
and has no relationship to the time within which the obligation to comply with
the Contract Documents may be sought to be enforced, nor to the time within
which proceedings may be commenced to establish the Contractor's liability with
respect to the Contractor's obligations other than specifically to correct the
Work.

          12.3 ACCEPTANCE OF NONCONFORMING WORK

               12.3.1  If the Owner prefers to accept Work which is not in
accordance with the requirements of the Contract Documents, the Owner may do so
instead of requiring its removal and correction, in which case the Contract Sum
will
<PAGE>

be reduced as appropriate and equitable. Such adjustment shall be effected
whether or not final payment has been made.

13.  MISCELLANEOUS PROVISIONS

that party shall nevertheless remain legally responsible for all obligations
under the Contract.

               13.2.2  The Owner may, without consent of the Contractor, assign
the Contract to an institutional lender providing construction financing for the
Project. In such event, the lender shall assume the Owner's rights and
obligations under the Contract Documents. The Contractor shall execute all
consents reasonably required to facilitate such assignment.

available by law.

writing.

time. Unless otherwise provided, the Contractor shall make arrangements of such
tests, inspections and approvals with an independent testing laboratory or
entity acceptable to the Owner, or with the appropriate public authority, and
shall bear all related costs of tests, inspections and approvals. The Contractor
shall give the [TEXT DELETED] Owner timely notice of when and where tests and
inspections are to be made so that the [TEXT DELETED] Owner may be present for
such procedures. The Owner shall bear costs of tests, inspections or approvals
which do not become requirements until after bids are received or negotiations
concluded.

               13.5.2  If the [TEXT DELETED] Owner or public authorities having
jurisdiction determine that portions of the Work require additional testing,
inspection or approval not included under Subparagraph 13.5.1, the [TEXT
DELETED] Owner will, [TEXT DELETED] instruct the Contractor to make arrangements
for such additional testing, inspection or approval by an entity acceptable to

shall be at the Contractor's expense.

               13.5.4  Required certificates of testing, inspection or approval

               13.5.5  If the [TEXT DELETED] Owner is to observe tests,
inspections or approvals required by the Contract Documents, the [TEXT DELETED]
Owner will do so promptly and, where practicable, at the normal place of
testing.

               13.5.6  Tests or inspections conducted pursuant to the Contract
Documents shall be made promptly to avoid unreasonable delay in the Work.

7.3.8  The Owner and the Design/Builder waive all rights against each other and
the Architect and other design professionals, contractors, subcontractors,
agents and employees; each of the other, for damages caused by fire or other
perils to the extent covered by property insurance obtained pursuant to this

procedures provided in Article 10.  If distribution of insurance proceeds by
arbitration is required, the arbitrators will direct such distribution.

7.3.11  Partial occupancy or use prior to Substantial Completion shall not
commence until the insurance company or companies providing property insurance
have consented to such partial occupancy or use by endorsement or otherwise.
The Owner and the Design/Builder shall take reasonable steps to obtain consent
of the insurance company or companies and shall not, without mutual written
consent, take any action with respect to partial occupancy or use that would
cause cancellation, lapse or reduction of coverage.

7.4     LOSS OF USE INSURANCE

                              CHANGES IN THE WORK

8.1    CHANGES

8.1.1  Changes in the Work may be accomplished after execution of this Part 2
Agreement, without invalidating this Part 2 Agreement by Change Order,
Construction Change Directive, or order for a minor change in the Work, subject
to the limitations stated in the Contract Documents.

8.1.2  A Change Order shall be based upon agreement between the Owner and the
Design/Builder, a Construction Change Directive may be issued by the Owner
without the agreement of the Design/Builder, an order for a minor change in the
Work may be issued by the Design/Builder alone.

8.1.3  Changes in the Work shall be performed under applicable provisions of the
Contract Documents, and the Design/Builder shall proceed promptly, unless
otherwise provided in the Change Order, Construction Change Directive, or order
for a minor change in the Work.

8.1.4  If unit prices are stated in the Contract Documents or subsequently
agreed upon, and if quantities originally contemplated are so changed in a
proposed Change Order or Construction Change Directive that application of such
unit prices to quantities of Work proposed will cause substantial inequity to
the Owner or the Design/Builder, the applicable unit prices shall be equitably
adjusted.

8.2    CHANGE ORDERS

8.2.1  A Change Order is a written instrument prepared by the Design/Builder and
signed by the Owner and the Design/Builder, stating their agreement upon all of
the following:

       .1   a change in the Work;

       .2   the amount of the adjustment, if any, in the Contract Sum; and
<PAGE>

       .3   the extent of the adjustment, if any, in the contract Time.

8.2.2  If the owner requests a proposal for a change in the Work from the
Design/Builder and subsequently elects not to proceed with the change, a Change
Order shall be issued to reimburse the Design/Builder for any costs incurred for
estimating services, design services or preparation of proposed revisions to the
Contract Documents.

8.3    CONSTRUCTION CHANGE DIRECTIVES

8.3.1  A Construction Change Directive is a written order prepared and signed by
the Owner, directing a change in the Work prior to agreement on adjustment, if
any, in the Contract Sum or Contract Time, or both.

8.3.2  Except as otherwise agreed by the Owner and the Design/Builder, the
adjustment to the Contract Sum shall be determined on the basis of reasonable
expenditures and savings of those performing the Work attributable to the
change, including the expenditures for design services and revisions to the
Contract Documents.  In case of an increase in the Contract Sum, the cost shall
include a reasonable allowance for overhead and profit.  In such case, the
Design/Builder shall keep and present an itemized accounting together with
appropriate supporting date for inclusion in a Change Order.  Unless otherwise
provided in the Contract Documents, costs for these purposes shall be limited to
the following:

       .1   costs of lab or, including social security, old age and unemployment
            insurance, fringe benefits required by agreement or custom, and
            workers' compensation insurance;

       .2   costs of materials, supplies and equipment, including cost of
            transportation, whether incorporated or consumed;

       .3   rental costs of machinery and equipment exclusive of hand tools,
            whether rented from the Design/Builder or others;

       .4   costs of premiums for all bonds and insurance permit fees, and
            sales, use or similar taxes;
<PAGE>

       .5   additional costs of supervision and field office personnel directly
            attributable to the change; and fees paid to the Architect,
            engineers and other professionals.

8.3.3  Pending final determination of cost to the Owner amounts not in dispute
may be included in Applications for Payment.  The amount of credit to be allowed
by the Design/Builder to the Owner for deletion or change which results in a net
decrease in the Contract Sum will be actual net cost.  When both additions and
credits covering related Work or substitutions are involved in a change, the
allowance for overhead and profit shall be figured on the basis of the net
increase, if any, with respect to that change.

8.3.4  When the Owner and the Design/Builder agree upon the adjustments in the
Contract Sum and Contract Sum and Contract Time, such agreement shall be
effective immediately and shall be recorded by preparation and execution of an
appropriate Change Order.

8.4    MINOR CHANGES IN THE WORK

8.4.1  The Design/Builder shall have authority to make minor changes in the
Construction Documents and construction consistent with the intent of the
Contract Documents when such minor changes to not involve adjustment in the
Contract Sum or extension of the Contract Time.  The Design/Builder shall
promptly inform the Owner, in writing, of minor changes in the Construction
Documents and construction. [TEXT DELETED]

8.5    CONCEALED CONDITIONS

8.5.1  If conditions are encountered at the site which are (1) subsurface or
otherwise concealed physical conditions which differ materially from those
indicated in the Contract Documents, or (2) unknown physical conditions of an
unusual nature which differ materially from those ordinarily found to exist and
generally recognized as inherent in construction activities of the character
provided for in the Contract Documents, then notice by the observing party shall
be given to the other party promptly before conditions are disturbed and in no
event later than 21 days after first observance of the conditions.  The Contract
Sum shall be equitably adjusted for such
<PAGE>

concealed or unknown conditions by Change Order upon claim by either party made
within 21 days after the claimant becomes aware of the conditions. Any
information on the design drawings for the building in which the site is located
shall not be deemed a "concealed condition."

8.6    REGULATORY CHANGES

8.6.1  The Design/Builder shall be compensated for changes in the construction
necessitated by the enactment or revision of codes, laws or regulations
subsequent to the [TEXT DELETED] execution of this Agreement.


                                   ARTICLE 9
                              CORRECTION OF WORK

9.1    The Design/Builder shall promptly correct Work rejected by the Owner or
known by the Design/Builder to be defective or failing to conform to the
requirements of the Contract Documents, whether observed before or after
Substantial Completion and whether or not fabricated, installed or completed.
The Design/Builder shall bear costs of correcting such rejected Work, including
testing and inspections.

9.2    If, within one (1) year after the date of Substantial Completion of the
Work or, after the date for commencement of warranties established in a written
agreement between the Owner and the Design/Builder, or by terms of an applicable
special warranty required by the Contract Documents, any of the Work is found to
be not in accordance with the requirements of the Contract Documents, the
Design/Builder shall correct it promptly after receipt of a written notice from
the Owner to do so unless the Owner has previously given the Design/Builder a
written acceptance of such condition.

9.3    Nothing contained in this Article 9 shall be construed to establish a
period of limitation with respect to other obligations which the Design/Builder
might have under the Contract Documents.  Establishment of the time period of
one (1) year as described in Subparagraph 9.2 relates only to the specific
obligation of the Design/Builder to correct the Work, and has no relationship to
the time within which
<PAGE>

the obligation to comply with the Contract Documents may be sought to be
enforced, nor to the time within which proceedings may be commenced to establish
the Design/Builder's liability with respect to the Design/Builder's obligations
other than specifically to correct the Work.

9.4    If the Design/Builder fails to correct nonconforming Work as required or
fails to carry out Work in accordance with the Contract Documents, the Owner, by
written order signed personally or by an agent specifically so empowered by the
Owner in writing, may order the Design/Builder to stop the Work, or any portion
thereof, until the cause for such order has been eliminated; however, the
Owner's right to stop the Work shall not give rise to a duty on the part of the
Owner to exercise the right for benefit of the Design/Builder or other persons
or entities.

9.5    If the Design/Builder defaults or neglects to carry out the Work in
accordance with the Contract Documents and fails within seven (7) days after the
receipt of written notice from the Owner to commence and continue correction of
such default or neglect with diligence and promptness, the Owner may give a
second written notice to the Design/Builder and seven (7) days following receipt
by the Design/Builder of that second written notice and without prejudice to
other remedies, the Owner may have, correct such deficiencies.  In such case an
appropriate Change Order shall be issued deducting from payments then or
thereafter due the Design Builder, the costs of correcting such deficiencies.
If the payments then or thereafter due the Design/Builder are not sufficient to
cover the amount of the deduction, the Design/Builder shall pay the difference
to the Owner.  Such action by the Owner shall be subject to dispute resolution
procedures as provided in Article 10.


                                   ARTICLE 10

10.1   Subject to Article 14.9 Claims, disputes or other matters in question
arising out of or relating to this Part 2 Agreement or breach thereof shall be

arbitration be made after the date when institution of legal or equitable
proceedings based on such claim, dispute or other matter in question would be
barred by the applicable statutes of repose or limitations.

10.4   An arbitration pursuant to this Article may be joined with an arbitration
involving common issues of law or fact between the Design/Builder and any person
or entity with whom the Design/Builder has a contractual obligation to arbitrate
disputes.  No other arbitration arising out of or relating to this Part 2
Agreement shall include, by consolidation, joinder or in any other manner, an
additional person or entity not a party to this Part 2 Agreement or not a party
to an agreement with the Design/Builder, except by written consent containing a
specific reference to this Part 2 Agreement signed by the Owner, the
Design/Builder and any other person or entities sought to be joined.  Consent to
arbitration involving an additional person or entity shall not constitute
consent to arbitration of any claim, dispute or other matter in question not
described in the written consent or with a person or entity not named or
described therein.  The foregoing agreement to arbitrate and other agreements to
arbitrate with an additional person or entity duly consented to by the parties
to this Part 2 Agreement shall be specifically enforceable in accordance with
applicable law in any court having jurisdiction thereof.

10.5   The award rendered by the arbitrator or arbitrators shall be final, and
judgment may be entered upon it in accordance with applicable law in any court
having jurisdiction thereof.

related to the Project with the Owner's own forces, and to award separate
contracts in connection with other portions of the Project or other construction
or operations on the site under conditions of insurance and waiver of
subrogation identical to the provisions of this Part 2 Agreement. If the
Design/Builder claims that delay or additional cost is involved because of such
action by the Owner, the Design/Builder shall assert such claims as provided in
Subparagraph 11.4.

11.3.2  The Design/Builder shall afford the Owner's separate contractors
reasonable opportunity for introduction and storage of their materials and
equipment and performance of their activities and shall connect and coordinate
the Design/Builder's construction and operations with theirs as required by the
Contract Documents.

11.3.3  Costs caused by delays or by improperly timed activities or defective
construction shall be borne by the party responsible therefor.


11.4    CLAIMS FOR DAMAGES

or indirectly employed by the Design/Builder or anyone for whose acts the
Design/Builder may be liable, regardless of whether or not such claim, damage,
loss or expense is caused in part by a party indemnified hereunder. Such
obligation shall not be construed to negate, abridge, or reduce other rights or
obligations of indemnity which would otherwise exist as to a party or person
described in this Paragraph 11.5.

11.5.2  In claims against any person or entity indemnified under this Paragraph
11.5 by an employee of the Design/Builder, anyone directly or indirectly

     the job site.  Contractor shall employ, and shall require its
     Subcontractors to employ, workers on the Work who will at all times work in

     stopped or materially delayed due to a labor dispute involving the

ARTICLE 7 - CHANGES IN THE WORK

Add the following at the end of Subparagraph 7.1.1:

     The parties hereby acknowledge the Project is being designed and built on a
     so-called "fast track" basis.  As such, the Drawings and Specifications are
     not complete as of the date hereof.  The development of the Drawings and
     Specifications may require multiple rounds of drafting, review, comments,
     changes and modifications.  The Project Construction Budget, and the
     Project Schedule (including the date of Substantial Completion) shall be
     subject to adjustment in connection with such changes and modifications to
     the Drawings and Specifications.  However, subject to the provisions of
     Section 7.2.1, no such change or modification to the Drawings and
     Specifications shall constitute (or require) a "Change Order" or entitle
     Contractor to any claim for an adjustment to Contractor's cost and fee,
     notwithstanding whether any such change or modification requires
     alteration, removal, replacement or reperformance of Work that has been
     completed, provided the Work requested can be completed by the date of
     11/1/99.  Should the "Change Order" cause an extension of Contractor
     service beyond the date of 11/1/99, the Contractor will provide a revised
     Exhibit B for the cost of the administration of the change with a fee
     calculation as per the terms of Article 17.2.1.

Add the following at the end of Subparagraph 7.1.2:

     No Change Order involving an adjustment in the Contract Sum or an extension
     of the Contract Time shall in any event be issued except with the written
     approval of Owner.

Add the following at the end of Paragraph 7.1:

     7.1.4  Refinements and detailing will be accomplished from time to time
     with respect to the Drawings and Specifications, including the addition of
     items or materials that may have been omitted from the Drawings or
     Specifications but that are necessary to complete a detail shown, specified
     or reasonably inferable therefrom.  If any item or material shown on the
     Drawings is omitted from or excepted in the Specifications, or vice versa,
     or if any omitted item or material is inferable to complete the detail
     shown or specified, Contractor shall, without any increase in the Contract
     Sum or extension of the Contract Time, furnish and install such item or
     material of type and quality as established by the balance of the detail
     shown and specified.

     7.1.5  Contractor represents and warrants that, to the extent reasonable
     under the circumstances, it has studied and familiarized itself with the
     Contract Documents and the site and the utility services provided thereto.
     Any change in the Work required because Contractor failed to anticipate or
     discover a condition at the site or failed to anticipate or discover that
     the utility services to the site or the Contract Documents are insufficient
     to complete the Work, which change could have been avoided had Contractor
     properly studied and familiarized itself with the Contract Documents and
     the site and the utility services provided thereto, shall not result in any
     increase in the Contract Sum or extension of the Contract Time.

     7.1.6  If the adjustment to the Contract Sum resulting from a change in the
     Work is determined under Paragraph 7.3.6, the following shall apply:

          .1  The cost of the Work shall include an allowance for Contractor's
               overhead or profit in the form of an adjustment in Contractor's
               Fee (but only in accordance with Article 17 hereof) pursuant to
               the terms of the Contract, subject to Owner's approval in all
               cases.

          .2  On Work performed by Subcontractors (excluding the Contractor's
               architect and engineer), but not by Sub-subcontractors, the
               Subcontractors' allowance for overhead and profit shall not
               exceed 15% of direct costs.

                                       5
<PAGE>

          .3  On Work performed by Sub-subcontractors, the subcontractors'
               allowance for overhead and profit shall not exceed 10% of total
               direct costs.

Delete Subparagraph 7.2.1 and insert the following:

     A "Change Order" is a written order to the Contractor signed by the Owner
     or its authorized agent issued after the execution of this Agreement and
     the finalization of any applicable Drawings and Specifications, authorizing
     a Change in the Project or the method or manner of performance and/or an
     adjustment in the Project Construction Budget or the Substantial Completion
     Date. Subcontractors shall be entitled to adjustment of their fees and
     costs for Change Order work in accordance with the terms of their
     respective Subcontracts. The Contractor shall be entitled to compensation
     for all Costs of the Project incurred by Contractor in connection with the
     applicable Change Order work as per the parameters outlined in Section
     7.1.1 above.

In the second and fifth lines of Subparagraph 7.3.6 change "Architect" to
"Owner."

Add the following new Subparagraph at the end of Paragraph 7.3:

     7.3.10  Contractor shall submit to Owner, within seven (7) days after a
     written request therefor from Owner or within seven (7) days after an order
     to proceed with a change in the Work pending issuance of a Change Order, an
     accurate written estimate of any increase or decrease in costs and of any
     delay in the time of completion that will result from the proposed change.
     The estimate shall indicate the quantity and unit price of each item of
     materials and the number of hours of work and hourly rate for each class of
     labor, as well as the description and amounts of all other costs and
     sources of delay.

ARTICLE 8 - TIME

                    extras for which no Change Order has been processed, and
                    listing all Change Orders that have been processed that
                    affect the Contract Sum;

          (ii)      Such other certifications or evidence supporting
                    Contractor's right to payment as the Owner's landlord may
                    require;

          (iii)    an affidavit of Contractor that all amounts owed to
                    Subcontractors, to suppliers of materials, and to laborers
                    for work and materials, furnished for the purpose of the
                    performance of the Work or otherwise related to

                    such Work for which payment is made have been paid in full,
                    and waiving any claim for a mechanics or materialman's lien
                    on the Work;

          (iv)      a waiver and subordination of lien in form and substance
                    satisfactory to the Owner in accordance with California lien
                    law from each Subcontractor performing any portion of the
                    Work;

                    obligations, such as receipts, releases, certificates,
                    affidavits and subordinations and/or waivers of liens

     Payment by the Owner to the Contractor less retainage as hereinafter
     provided, shall be made in accordance with the terms of this Agreement.
     The Owner shall withhold from each monthly payment an amount equal to ten
     percent (10%) on account of each Subcontractor's payment. At such time as
     each Subcontractor's Work is fifty percent (50%) complete, no further
     retainage will be withheld, provided, in the Owner's and Contractor's
     opinions, the Subcontractor is performing satisfactorily.  The Contractor
     will be paid one hundred percent (100%) of its direct costs and fee earned
     to the billing date.  There will be no retainage, however, on the Design
     Phase.

Add the following subparagraph to 9.3.3:

     The submission of any Application for Payment shall, upon receipt of such
     payment and to the fullest extent permitted by law, be conclusively deemed
     to waive all liens with respect to such work, materials and labor to which
     Contractor then may be entitled; provided, however, that in no event shall
     such waiver of lien rights waive right to payment for such work, materials
     and labor.

     If a lien or notice of contract is filed or claimed against the Work by any
     Subcontractor, Sub-Subcontractor, laborer or supplier of materials,
     Contractor shall immediately bond such lien or cause such lien to be
     discharged.  Any payment due Contractor under the Contract Documents shall
     be reduced by an amount up to two hundred percent (200%) of the amount of
     any lien until such lien is removed as of record and/or bonded.

Insert the following:

     9.4.2  An Application for Payment will constitute a representation by
     Contractor to Owner that the Work has progressed to the point indicated and
     that the quality of the Work is in accordance with the Contract Documents.

Insert the following at the beginning of Subparagraph 9.5.1:

     "Owner may withhold payment in whole or in part, to the extent reasonably
     necessary to protect Owner, if the representations in Subparagraph 9.4.2
     cannot be made.  The Owner may also withhold payment or, because of
     subsequently discovered evidence, may nullify the whole or a part of a
     payment previously issued, to such extent as necessary to protect the Owner
     from loss for which the Contractor is responsible, including loss resulting
     from acts and omissions described in Subparagraph 3.3.2 because of:"

Delete Subparagraph 9.7.1.  Section 12.2 as revised in A191, Part 2 to govern

     before being compensated therefor by Owner), rebates and refunds, and all
     returns from sale of surplus materials and equipment, shall be credited to
     the Cost of the Project.  In the event of a discount offered by a
     subcontractor at the time of bid, Contractor shall inform and discuss with

     the Work hereunder, Contractor shall immediately take all steps necessary
     to deal with the Hazardous Materials in accordance with all applicable laws

     costs, including, without limitation, reasonable attorneys' fees,
     remediation costs and liability arising by virtue of such a release of
     Hazardous Materials in any form on or about the Project site as a result of
     the act, omission or neglect of Contractor or any of its contractors, or
     their respective employees, agents and representatives (and without any
     fault on the part of Owner, its separate contractors or their respective

Changes in the Project
- ----------------------

9.1.1   The parties hereby acknowledge the Project is being designed and built
on a so-called "fast track" basis. As such, the Drawings and Specifications are
not complete as of the date hereof. The development of the Drawings and
Specifications may require multiple rounds of drafting, review, comments,
changes and modifications. The Project Construction Budget and the Project
Schedule (including the date of Substantial Completion) shall be subject to
adjustment in connection with such

                                                                              11
<PAGE>

changes and modifications to the Drawings and Specifications. However, subject
to the provisions of Section 9.1.2 and 9.1.3 below, no such change or and
modification to the Drawings and Specifications shall constitute (or require) a
"Change Order" or entitle Construction Manager to any claim for an adjustment to
Construction Manager's fee, notwithstanding whether any such change or
modification requires alteration, removal, replacement or reperformance of Work
which has been completed provided the Work requested is within the parameters of
the scope of the Work outlined in, contemplated by or reasonably inferable from
Exhibit A and that the Work can be completed by the date of 1/28/00, which is
the date of cost projection outlined in Exhibit B and which date is subject to
extension to the extent not caused by or resulting from any negligence or
default of the Construction Manager. Should the "Change Order" be materially
different than the scope of Work outlined in, contemplated by or reasonably
inferable from Exhibit A and/or should the Change Order cause an extension of
Construction Manager service beyond the date of 1/28/00 (as the same may be
extended as aforesaid), but subject to the provisions of Section 7.2 hereof, the
Construction Manager will provide a revised Exhibit B for the cost of the
administration of the change with a fee calculation as per the terms of Article
7.2.1.

9.1.2  A "Change Order" is a written order to the Construction Manager signed by
the Tenant or his authorized agent issued after the execution of this Agreement
and the finalization of any applicable Drawings and Specifications, authorizing
a Change in the Project or the method or manner of performance and/or an
adjustment in the Project Construction Budget, the Construction Manager's fee or
the Substantial Completion Date. Trade Contractors shall be entitled to
adjustment of their fees and costs for Change Order work in accordance with the
terms of their respective Trade Contracts. The Construction Manager shall be
entitled to compensation for all Costs of the Project incurred by Construction
Manager in connection with the applicable Change Order work as per the
parameters outlined in Section 9.1.1 above.

9.1.3  Should (i) concealed conditions encountered in the performance of the
Work below the surface of the ground, or (ii) concealed or unknown conditions in
any existing structure which are at variance with the conditions indicated by
the Drawings, Specifications, or Tenant furnished information, or (iii) unknown
physical conditions below the surface of the ground or concealed or unknown
conditions in an existing structure which are of an unusual nature, differing
materially from those ordinarily encountered and generally recognized as
inherent in work of the character provided for in this Agreement be encountered,
then, to the extent that such conditions were not reasonably foreseeable by
Construction Manager, the Project Construction Budget and the Substantial
Completion Date shall be equitably adjusted by Change Order upon claim by either
party made within seven (7) days after the date of discovery of the applicable
condition (provided, however, that Construction Manager's fee shall not be
increased except to the extent that the applicable condition results in a delay
in the date of Substantial Completion, in which case Construction Manager's fee
shall be equitably adjusted). No such claim shall be valid unless so made. Any
change in the Project Construction Budget or the Substantial Completion Date or
Construction Manager's fee resulting from such claim shall be authorized only by
Change Order.

9.2    Claims for Additional Cost or Time
       ----------------------------------

9.2.1  If the Construction Manager wishes to make a claim for an extension in
the Substantial Completion Date, he shall give the Tenant written notice thereof
within seven (7) days time after the occurrence of the event giving rise to such
claim. This notice shall be given by the Construction Manager before proceeding
to execute any Work, except in an emergency endangering life or property in
which case the Construction Manager shall act, at his discretion, to prevent
threatened damage, injury or loss. Claims arising from delay shall be made
within seven (7) days time after the delay. No such claim shall be valid unless
so made. Any change in the Project Construction Budget or Substantial Completion
Date resulting from such claim shall be authorized by Change Order.

9.3    Minor Changes in the Project

in the Tenant's and the Construction Manager's opinions, the Trade Contractor is
performing satisfactorily. The Construction Manager will be paid one hundred
percent (100%) of its direct costs and fee earned to the billing date.

11.1.1 The Construction Manager shall maintain detailed statements, including

Work, Tenant shall release the retainage held by Tenant with respect to the Cost
of the Project, less an amount equal to 200% of the estimated cost of completing
any unfinished punchlist items, provided that said unfinished items are listed
separately and the estimated cost of completing any unfinished items likewise
listed separately. Thereafter, Tenant shall pay to Construction Manager, within
thirty (30) days of the Construction Manager's invoice, the amount retained for
incomplete items as each of said items is completed.

11.3   The Construction Manager shall pay all the amounts due Trade Contractors
or other persons with whom he has a contract within seven (7) days after receipt

Construction Manager shall submit to Tenant satisfactory evidence that all
payrolls, materials bills and other indebtedness connected with the Project have
been paid or otherwise satisfied, together with final lien waivers from each
Trade Contractor and Supplier.

11.4   If the Tenant should fail to pay the Construction Manager within seven
(7) days after the time the payment of any amount becomes due, then the
Construction Manager may, upon seven (7) additional days' written notice to the
Tenant and the Architect/Engineer, stop the Project until payment of the amount
owing has been received.

                                                                              13
<PAGE>

11.5  Payments due but unpaid shall bear interest at the rate of one percent
above the Fleet/Norstar Bank prime rate prevailing on the date payment was due.

11.6  In the event a lien or notice of contract is filed or claimed against the
Project site by any Trade Contractor, laborer or supplier of materials, the

showing such coverage to be in force shall be filed with the Tenant prior to
commencement of the Work.

12.2.6    In the event the Tenant elects to provide insurance coverage for the
Construction Manager and/or its Trade Contractors and Trade Subcontractors via a

not afford the same coverage as stated herein above, the Construction Manager
may purchase a Difference in Conditions policy, the premium for which shall be
reimbursed to the Construction Manager as a Cost of the Project.

12.3  Tenant's Liability Insurance
      ----------------------------

12.3.1    The Tenant shall be responsible for purchasing and maintaining his own
liability insurance and, at his option, may purchase and maintain such insurance
as will protect him against claims which may arise from operations under this
Agreement.

12.4  Insurance to Protect Project
      ----------------------------

12.4.1    The Tenant shall purchase and maintain property insurance in a form
acceptable to the Construction Manager upon the entire Project for the full cost
of replacement as of the time of any loss. This insurance shall include as named
insured the Tenant, Landlord, the Construction Manager, Trade Contractors and
their Trade Subcontractors and shall insure against loss from the perils of
Fire, Extended Coverage, and shall include "All Risk" insurance for physical
loss or damage including, without duplication of coverage, at least theft,
vandalism, malicious mischief, transit, collapse, flood, and earthquake. The
Tenant will increase limits of coverage, if necessary, to reflect estimated
replacement cost. The Tenant will be responsible for any co-insurance penalties
or deductibles (provided, however, that Construction Manager shall pay the
amount of the one thousand dollar ($1,000) deductible to the extent that the
applicable loss or claim arises from any negligence of Construction Manager or
any Trade Contractor). If the Project covers an addition to or is adjacent to an
existing building, the Construction Manager, Trade Contractors and their Trade
Subcontractors shall be named as additional insurers under the Tenant's Property
Insurance covering such building and its contents.

12.4.1.1  If the Tenant finds it necessary to occupy or use a portion or
portions of the Project prior to Substantial Completion thereof, such occupancy
shall not commence prior to a time mutually agreed to by the Tenant and
Construction Manager and to which the insurance company or companies providing
the property insurance have consented by endorsement to the policy or policies.
This insurance shall not be cancelled or lapsed on account of such partial
occupancy.  Consent of the Construction Manager and of the insurance company or
companies to such occupancy or use shall not be unreasonably withheld.

                                                                              15
<PAGE>

12.4.2  The Tenant shall purchase and maintain such boiler and machinery
insurance as may be required or necessary. This insurance shall include the
interests of the Tenant, the Construction Manager, Trade Contractors and their
Trade Subcontractors in the Work.

12.4.3  The Tenant shall purchase and maintain such insurance as will protect
the Tenant, Landlord and Construction Manager against loss of use of Tenant's
and Landlord's property due to those perils insured pursuant to Subparagraph
12.4.1. Such policy will provide coverage for expediting expenses of materials,
continuing overhead of the Tenant, Landlord and Construction Manager, necessary
labor expense, including overtime, and other determined exposures approved by
Tenant. Exposures of the Tenant, Landlord and the Construction Manager shall be
determined by mutual agreement and separate limits of coverage fixed for each
item.

12.4.4  The Tenant shall file a copy of certificates for all such policies with
the Construction Manager before an exposure to loss may occur. Copies of any
subsequent endorsements will be furnished to the Construction Manager. The
Construction Manager will be given sixty (60) days notice of cancellation, non-
renewal, or any endorsements restricting or reducing coverage. If the Tenant
does not intend to purchase such insurance, he shall inform the Construction
Manager in writing prior to the commencement of the Work. The Construction
Manager may then effect insurance which will protect the interest of himself,
the Trade Contractors and their Trade Subcontractors in the Project, the cost of
which shall be a Cost of the Project pursuant to Article 8, and the Project
Construction Budget shall be increased accordingly. If the Construction Manager
is damaged by failure of the Tenant to purchase or maintain such insurance or to
so notify the Construction Manager, the Tenant shall bear all reasonable costs
properly attributable thereto.

12.5  Property Insurance Loss Adjustment
      ----------------------------------

12.5.1  Any insured loss shall be adjusted by the Tenant and/or the Landlord and
made payable to the Tenant and/or the Landlord as trustees for the insured, as
their interests may appear, subject to any applicable mortgagee clause.

12.5.2  Upon the occurrence of an insured loss, monies received will be
deposited in a separate account and the trustees shall make distribution in
accordance with the agreement of the parties in interest.

12.6  Waiver of Subrogation
      ---------------------

12.6.1  The Tenant and Construction Manager waive all rights against each other,
the Architect/Engineer, Trade Contractors, and their Trade Subcontractors for
damages caused by perils covered by insurance provided under Paragraph 12.4,
except such rights as they may have to the proceeds of such insurance held by
the Tenant and Construction Manager as trustees. The Construction Manager shall
require similar waivers from all Trade Contractors and their Trade
Subcontractors.

12.6.2  The Tenant and Construction Manager waive all rights against each other
and the Architect/Engineer, Trade Contractors and their Trade Subcontractors for
loss or damage to any equipment used in connection with the Project and covered
by any property insurance. The Construction Manager shall require similar
waivers from all Trade Contractors and their Trade Subcontractors.

12.6.3  The Tenant waives subrogation against the Construction Manager,
Engineer, Trade Contractors, and their Trade Subcontractors on all property and
consequential loss policies carried by the Tenant on adjacent properties and
under property and consequential loss policies purchased for the Project after
its completion.

12.6.4  If the policies of insurance referred to in this Paragraph require an
endorsement to provide for continued coverage where there is a waiver of
subrogation, the owners of such policies will cause them to be so endorsed.

12.6.5  The Construction Manager shall require all Trade Contractors to carry
and maintain until completion of such Trade Contractor's work insurance meeting
at least the following requirements: (i) worker's compensation having the
statutory coverage, (ii) comprehensive general liability insurance having

                                                                              16
<PAGE>

coverage limits which are commercially reasonable for the applicable trades and
approved by Tenant, and (iii) owned, non-owned and hired motor vehicle insurance
having coverage limits which are commercially reasonable for the applicable
trades and approved by Tenant. Such policies of insurance shall name Tenant and
Landlord as additional insureds.

13.1  Termination by the Construction Manager
      ---------------------------------------

13.1.1  If the Project, in whole or substantial part, is stopped for a period of
thirty days under an order of any court or other public authority having
jurisdiction, or as a result of an act of government, such as a declaration of a
national emergency making materials unavailable, through no act or fault of the
Construction Manager, or if the Project should be stopped for a period of thirty
days by the Construction Manager for the Tenant's failure to make payment
thereon, then the Construction Manager may, upon seven days' written notice to
the Tenant, terminate this Agreement and recover from the Tenant payment for all
work executed, the Construction Manager's Fee earned to date (which shall be in

his own forces, the Tenant shall have the right, but not the obligation, after
seven days' written notice during which period the Construction Manager fails to
perform such obligation, to make good such deficiencies and charge Construction
Manager for all costs incurred for the remedy of such deficiencies.

13.2.2  If the Construction Manager is adjudged a bankrupt, or if he makes a
general assignment for the benefit of his creditors, or if a receiver is
appointed on account of his insolvency, or if he refuses or fails, except in
cases for which extension of time is provided, to supply enough properly skilled
workmen or proper materials (and such default is not cured within seven (7) days
after notice from Tenant), or if he fails to make proper payment to Trade
Contractors or for materials or labor, or violates any laws, ordinances, rules,
regulations or orders of any public authority having jurisdiction, or otherwise
is guilty of a violation of any provision of this Agreement (and such default is
not cured within seven (7) days after notice from Tenant), then the Tenant may,
without prejudice to any right or remedy, upon giving the Construction Manager
and his surety, if any, written notice, terminate this Agreement and take
possession of the site and of all materials, equipment, tools, construction
equipment and machinery thereon owned by the Construction Manager and may finish
the Project by whatever method he may deem expedient.  In such case, the
Construction Manager shall not be entitled to receive any further payment until
the Project is finished.  The Construction Manager shall be responsible for
damages incurred by the Tenant arising as a direct result of the Construction
Manager's default hereunder.

13.2.3. The Tenant reserves the right to terminate this agreement for
convenience at any time.  Tenant will provide seven (7) days written notice to
the Construction Manager and will pay all costs incurred to that point in time
