  This summary highlights the key information contained in this prospectus.
Because it is a summary, it does not contain all of the information you should
consider before making an investment decision. You should read the entire
prospectus carefully, including the section titled "Risk Factors" and the
financial statements and the notes relating to those statements. We will refer
to Digex, Incorporated and our predecessors as "Digex," "we," "us" and "our."
We will refer to our parent company, Intermedia Communications Inc., and its
subsidiaries, as "Intermedia."
 
                                     Digex
 
Our Company
 
  Digex is a leading provider of Internet hosting services to businesses and
institutions implementing complex, interactive Web sites and Web-based
applications. Our offerings include Web site and application hosting,
enterprise and consulting services. From major corporations to Internet start-
ups, our customers leverage our services to rapidly and cost-effectively deploy
secure and reliable business solutions including on-line banking, on-line
procurement and electronic retailing. We provide the computer hardware,
software, network technology, and systems management necessary to offer our
customers comprehensive outsourced Web site hosting solutions.
 
  We believe our singular focus on delivering mission-critical Web site and
application hosting solutions has been the major contributor to our growth.
Digex currently provides hosting services to over 550 customers, including
American Century Investments, Budget Rent-A-Car, Forbes, J. Crew, Kraft,
Universal Studios and Nike. We operate two state-of-the-art data centers
strategically positioned on the east and west coasts of the United States. In
these data centers, we house over 1,300 Windows NT and UNIX-based servers which
we own and manage. Our revenues have grown at a compounded annual growth rate
of 184% over the past two years from $2.8 million in 1996 to $22.6 million in
1998. Our revenue for the three months ended March 31, 1999 was $9.4 million.
The following are among the key factors that we believe will continue to drive
our growth:
 
  .  a highly scalable operating platform which was designed to facilitate
     the rapid, cost-efficient implementation and expansion of customers' Web
     site hosting initiatives;
 
  .  an experienced management team and technical experts, who in the
     aggregate hold over 200 technical certifications from leading companies
     such as Cisco Systems, Microsoft and Sun Microsystems;
 
  .  a highly skilled research and development organization dedicated to
     identifying the best available tools, technologies and processes;
 
  .  a growing, geographically distributed direct sales force; and
 
  .  a network of over 120 business partnership alliances which provide
     complementary design, development and integration services for our
     customers and which represent a significant source of new customer
     referrals for Digex.
 
Our Market Opportunity
 
  According to Forrester Research, Inc., the Web site hosting market is
projected to increase to over $10.5 billion by 2002, of which $8.0 billion is
expected to be complex Web site management services. In addition to the overall
expansion and ever-increasing ubiquity of the Internet, we believe one of the
key drivers of growth in the Web hosting industry is the increasing number of
businesses that have elected to outsource the management of their Web sites and
related operations. Web sites are mission-critical for virtually all Web-
centric companies and are becoming increasingly strategic for many mainstream
enterprises. At the same time, these operations and applications are becoming
more complex and challenging to operate. We offer
 
                                       3
<PAGE>
 
customers a comprehensive outsourcing solution designed to reduce costs, speed
implementation, reduce technology risks and provide guaranteed operating
performance. Key advantages we offer our customers include:
 
  .  a comprehensive suite of Web site and application hosting services;
 
  .  high-performance Internet and private network connectivity;
 
  .  responsive, 24-hour a day customer care and technical support;
 
  .  secure, state-of-the-art, fault-tolerant data centers; and
 
  .  predictable monthly fees.
 
Our Services
 
  We offer a full range of services to meet the rapidly evolving requirements
of complex Web sites, including:
 
  .  Web site management services which provide operations support for
     Windows NT and UNIX dedicated servers, server collocation, and network
     connectivity;
 
  .  integrated business solutions, which involve the hosting of leading Web-
     enabled business software applications such as electronic commerce,
     sales force automation and customer care;
 
  .  enterprise services such as firewall management, stress testing and
     customized Web site activity reporting; and
 
  .  consulting services including capacity planning, disaster recovery
     planning, migration planning and database optimization.
 
Our Strategy
 
  Our objective is to shape and lead the global market for Web site and
application hosting solutions. We intend to achieve this goal through a
strategy focused on the following:
 
  .  Expanding Our Premier Web Site Hosting Capabilities. We believe our
     scalable, open architecture will enable us to expand our operations
     while simultaneously maintaining the highest service levels. In
     addition, we believe our architecture will allow us to attain higher
     revenues, lower marginal unit costs and increase operating margins. In
     conjunction with this expansion, we plan to add additional data center
     capacity both domestically and internationally as appropriate to meet
     anticipated customer demand.
 
  .  Addressing Industry-Specific Customer Needs. Our marketing and operating
     strategy is designed to be market-driven. We intend to continue to focus
     on addressing the unique needs of our targeted customer base. We focus
     on specific industries which we believe have the highest propensity to
     outsource the management of complex, mission-critical Web sites.
 
  .  Developing Next Generation Service Offerings. As the underlying
     technology and functionality of the Internet evolves, we believe
     customers will continuously demand new and increasingly more robust
     services. Capitalizing on our strong technical skills and delivery
     platforms, we intend to be a leading provider of next generation Web-
     based service offerings.
 
  .  Expanding Capabilities Through Selective Strategic Partnering and
     Acquisitions. We intend to expand our network of strategic partnerships
     and to opportunistically acquire related businesses in order to cost-
     effectively augment our existing services, technologies, infrastructure,
     geographic presence or customer base.
 
Our History
 
  Our business started in 1996, as the Web site hosting unit (the
"Predecessor") of Business Internet, Inc. (previously known as DIGEX,
Incorporated), a company that was principally an Internet access and Web site
hosting services provider. Business Internet (at the time known as DIGEX,
Incorporated) went public in
 
                                       4
<PAGE>
 
October 1996, and was acquired by Intermedia in July 1997. In contemplation of
this offering, we were incorporated as Digex, Incorporated on April 27, 1999.
On that date, Business Internet contributed our assets to the newly formed
Digex, Incorporated in order to effect a recapitalization of our business. As
of the date of this prospectus, Business Internet, a wholly-owned subsidiary of
Intermedia, owns 100% of our outstanding common stock.
 
Our Address and Telephone Number
 
  The address of our principal executive offices is One Digex Plaza,
Beltsville, Maryland 20705 and our telephone number is (301) 847-5000.

    option is exercised in full, as described in "Underwriting."
 
(2) The Class B Common Stock is fully convertible into Class A Common Stock, on
    a one-for-one basis, at any time at the option of the holder or upon the
    transfer of the Class B Common Stock to any person or entity not affiliated
    with Intermedia.
 
(3) Due to certain restrictions in the bond indentures of Intermedia, our
    indirect parent, we will be required to use all of the net proceeds of this
    offering to purchase or construct Telecommunications Related Assets. The
    term "Telecommunications Related Assets" is defined under "Risk Factors--
    Digex is controlled by Intermedia," and would include data centers and
    related capital expenditures. In addition, prior to the closing of this
    offering, we will make arrangements for Intermedia to purchase from us some
    of the Telecommunications Related Assets purchased with the net proceeds of
    this offering. We expect to be able to use the proceeds of such sales to
    Intermedia for working capital purposes and to fund operating losses. This
    arrangement is explained under "Use of Proceeds."

                             Summary Financial Data
 
  The following table sets forth summary financial information of Digex for the
period from July 7, 1997 (date of acquisition) to December 31, 1997 and the
year ended December 31, 1998, and of the Predecessor for the year ended
December 31, 1996 and the period from January 1, 1997 to July 6, 1997. The
selected historical financial information has been derived from Digex's and the
Predecessor's financial statements which have been audited by Ernst & Young LLP
and are included elsewhere in this prospectus.
 
  The following table also sets forth our pro forma financial information for
the year ended December 31, 1997. The pro forma financial information gives
effect to the purchase by Intermedia of Business Internet as if such
acquisition had occurred on January 1, 1997, but only includes financial
information for the Predecessor. The presentation of pro forma financial
information is made to permit useful comparison of results of operations
between periods presented. This pro forma financial information is not
necessarily indicative of the operating results we would have achieved if the
Predecessor had been acquired on January 1, 1997. The relationship between
Business Internet and the Predecessor is more fully described in note 1 to the
financial statements.
 
  You should read the summary financial and other data below in conjunction

(1) This amount represents a one-time charge to operations for the charge off
    of purchased in-process research and development related to the Predecessor
    in connection with Intermedia's purchase of Business Internet on July 7,
    1997.
 
(2) Pro forma basic and diluted net loss per share have been calculated
    assuming that the common shares issued in connection with our
    recapitalization in April 1999 were outstanding for all periods of Digex
    presented.
 
(3) EBITDA, before certain charges, consists of earnings (loss) before tax
    benefit, depreciation and amortization and the charge off of purchased in-
    process research and development. EBITDA, before certain charges, does not
    represent funds available for management's discretionary use and is not
    intended to represent cash flow from operations. EBITDA, before certain
    charges, should be considered only as an alternative to net loss as an
    indication of operating performance or cash flows as a measure of
    liquidity.
 
(4) As Adjusted gives effect to the offering as if it had occurred on December
    31, 1998.
 
(5)  We have historically participated in a centralized cash management system
     of Intermedia and, as a result, have not carried cash balances on our
     financial statements. With the closing of this offering, we will be
     maintaining and reporting cash balances in our financial statements.

                                  RISK FACTORS
 
  Investing in our Class A Common Stock involves a high degree of risk. You
should carefully consider the risks and uncertainties described below before
you purchase any of our Class A Common Stock. These risks and uncertainties are
not the only ones we face. Unknown additional risks and uncertainties, or ones
that we currently consider immaterial, may also impair our business operations.
 
  If any of these risks or uncertainties actually occur, our business,
financial condition or results of operations could be materially adversely
affected. In this event, the trading price of our Class A Common Stock could
decline, and you could lose all or part of your investment.
 
We have a limited operating history and our business model is still evolving.
 
  We were established in January 1996 to provide Web site hosting services for
businesses deploying complex, mission-critical Web sites, which remains our
primary focus. Our range of service offerings has changed since 1996 and our
business model is still new and developing. For example, we recently began
offering integrated business solutions and enterprise services. Because some of
our services are new, we cannot be sure that businesses will buy them. As a
result, the revenue and income potential of our business is unproven. Our
limited operating history makes predicting future results difficult. Our
prospects must be considered in light of the risks, expenses and difficulties
encountered by companies in the new and rapidly evolving market for Web hosting
services. To address these risks, among other things, we must:
 
  .  provide reliable, technologically current and cost-effective services;
 
  .  continue to upgrade and expand our infrastructure;
 
  .  market our brand name and services effectively;
 
  .  maintain and develop our business partnership alliances; and
 
  .  retain and attract qualified personnel.
 
We have a history of significant losses and expect these losses to continue in
the foreseeable future.
 
  We have experienced operating losses and negative cash flows from operations
in each annual period from inception. As of December 31, 1998, our accumulated
losses since January 1, 1996 have amounted to approximately $47.9 million. We
had a net loss of $16.6 million for the year ended December 31, 1998. While our
revenues have grown in recent periods, we cannot assure you that this growth
will continue. In connection with our expansion plans, we anticipate making
significant investments in sales, marketing, technical and customer support
personnel, as well as in our data center infrastructure. As a result of our
expansion plans, we expect our net losses and negative cash flows from
operations to continue for the foreseeable future. We cannot assure you that we
will ever become or remain profitable or that we will generate positive cash
flows from operations.
 
Our quarterly and annual results may fluctuate resulting in fluctuations in the
price of our Class A Common Stock.
 
  Our results of operations fluctuate on a quarterly and annual basis. We
expect to continue experiencing significant fluctuations in our future
quarterly and annual results of operations due to a variety of factors, many of
which are outside our control, including:
 
  .  demand for and market acceptance of our services;
 
  .  introductions of new services by us and our competitors;
 
  .  capacity utilization of our data centers;
 
  .  timing of customer installations;
 
  .  the mix of services we sell;
 
                                       9
<PAGE>
 
  .  customer retention;
 
  .  the timing and magnitude of our capital expenditures, including
     construction costs related to the expansion of our operations;
 
  .  changes in our pricing policies and those of our competitors;
 
  .  fluctuations in bandwidth used by customers;
 
  .  our retention of key personnel; and
 
  .  other general economic factors.
 
  For these and other reasons, in some future quarters, our results of
operations may fall below the expectations of securities analysts or investors,
which could negatively affect the market price of our Class A Common Stock.
 
We operate in a relatively new and evolving market with uncertain prospects for
growth.
 
  The market for Web site hosting and related services has only recently begun
to develop and is evolving rapidly. We cannot guarantee that this market will
ultimately prove viable. Our future growth, if any, will depend on the
continued trend of businesses to outsource their Web site hosting and
management systems, and our ability to market our services effectively. There
can be no assurance that the market for our services will develop, that our
services will be adopted, or that businesses, organizations or consumers will
use these Internet-based services in the degree or manner that we expect. It is
possible that at some point businesses may find it cheaper, more secure or
otherwise preferable to host their Web sites internally and decide not to
outsource the management of their Web sites. If we are unable to react quickly
to changes in the market, if the market fails to develop, or develops more
slowly than expected, or if our services do not achieve market acceptance, then
we are unlikely to become or remain profitable.
 
We operate in a highly competitive market with limited barriers to entry.
 
  The market for hosting Web sites is highly competitive. There are few
substantial barriers to entry and we expect intense competition from existing
and future competitors. The principal competitive factors in this market
include:
 
  .  quality of services and scalability of infrastructure;
 
  .  network capacity, reliability, security and adaptability to new
     technologies;
 
  .  Internet system engineering expertise;
 
  .  quality of customer service and support;
 
  .  relationships with marketing partners and vendors;
 
  .  variety of services offered;
 
  .  price;
 
  .  product innovation;
 
  .  financial resources; and
 
  .  brand name recognition.
 
  Our current and potential competitors in the market include:
 
  .  Web hosting service providers;
 
  .  local, regional, national and international Internet service providers
     ("ISPs");
 
  .  local, regional, national and international telecommunications
     companies; and
 
  .  large information technology outsourcing firms.
 
 
                                       10
<PAGE>
 
  Our competitors may operate in one or more of these areas and include
companies such as AboveNet Communications, AT&T, Cable & Wireless, Concentric
Network, EDS, Exodus Communications, Frontier/GlobalCenter, Globix, GTE, IBM,
Intel, Level 3 Communications, MCI WorldCom, PSINet, Qwest Communications
International, and USinternetworking.
 
  Many of our 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
possess. As a result, some of our competitors may be able to develop and expand
their network infrastructures and service offerings more quickly, adapt to new
or emerging technologies and changes in customer requirements more quickly,
take advantage of acquisition and other opportunities more readily, devote
greater resources to the marketing and sale of their products and adopt more
aggressive pricing policies than we can. In addition, some competitors have
entered and will likely continue to enter into joint ventures or alliances to
provide additional services which may be competitive with those we provide.
 
  Some of our competitors may be able to bundle other telecommunications
services in connection with their Web site hosting services, which could allow
them to reduce the relative prices of their Web site hosting services. We may
not be able to overcome the effects of any such price reductions. In addition,
we believe the Web hosting market is likely to experience consolidation in the
near future, which could result in increased price and other competition that
would make it more difficult for us to compete. See "Business--Competition."
 
Our data centers and equipment, and the networks we rely on, are sensitive to
harm from human actions and natural disasters. Any resulting disruption could
significantly damage our business and reputation.
 
  We believe our reputation for providing reliable service to our customers is
critical to our future success. Our ability to maintain and enhance our
reputation will depend on the integrity, performance and security of our data
centers and equipment, and of the network infrastructure of our connectivity
providers, including our principal provider, Intermedia. Our data centers and
equipment, and the networks we use, however, are subject to damage from human
error and tampering, natural disasters, power loss, capacity limitations,
software defects, breaches of security, physical break-ins, telecommunications
failures, intentional acts of vandalism and other factors that have caused, and
will continue to cause, interruptions in service or reduced capacity for our
customers. Despite precautions we have taken and plan to take, the occurrence
of a natural disaster or other unanticipated problems could result in
interruptions in the services we provide to our customers. Such an occurrence
could have a materially negative impact on our business and reputation.
 
  Our customers often maintain confidential information on the servers hosted
in our data centers. We strive to protect this information and our network from
unauthorized access, computer viruses and other security threats by using
encryption, authentication technology, biometric identifiers and security
guards. However, such measures have been circumvented in the past and could be
circumvented in the future. Our customer information and network may be
vulnerable to the accidental or intentional actions of Internet users, current
and former employees or others. Such acts could potentially jeopardize the
security of confidential information such as credit card and bank account
numbers stored in our system and our customers' computer systems. This could
result in liability to us and in our loss of existing or potential customers.
Additionally, the expense required to eliminate computer viruses and alleviate
other security problems could be significant and result in delays or
interruption of service to our customers. Any interruptions in service,
capacity limitations or security breaches could seriously harm our reputation
for reliable service. If our customers become dissatisfied with our level of
service, they may choose to discontinue their relationship with us.
 
  We provide our customers with service level agreements. Our customer
contracts provide that if we do not meet the required service levels, we may
have to provide credits to our customers. Additionally, in the event of any
harm to customers resulting from disruption of our service, security breaches,
damage to equipment or other circumstances, we could be held liable for
damages. Awards for such damages might exceed our liability insurance by an
unknown but significant amount and could harm our business.
 
                                       11
<PAGE>
 
We may be unable to secure sufficient network capacity to meet our future needs
on reasonable terms or at all.
 
  As the number of users and the amount of information they wish to transport
increases and the customers' requirements continue to change, we must continue
to expand and adapt our network arrangements. We may not be able to secure
additional network capacity as quickly and cheaply as we may need to meet
customer demand. Under our anticipated network services arrangement with
Intermedia, we will be required to purchase 70% of our non-peered network
capacity requirements from Intermedia. We cannot be sure that Intermedia will
be able to continue to meet our network capacity requirements. Under our
arrangement, Intermedia has 30 days to notify us if it is unable to meet our
network capacity requirements before we can contract with third-party suppliers
and then we can make relatively short-term arrangements with third-party
suppliers only to obtain the additional capacity which Intermedia is unable to
provide. This could delay our obtaining additional capacity and result in our
having to pay higher prices for such additional network capacity. Also, there
can be no assurance that additional network capacity will be available from
third-party suppliers as it is needed. As a result, we cannot assure you that
we will have access to sufficient network capacity. Our failure to achieve or
maintain high capacity data transmission could negatively impact service levels
to our existing customers and limit our ability to attract new customers, which
would harm our business.
 
Our business, in large part, depends on network services we receive from
Intermedia. Any disruption of these services or Intermedia's inability to
maintain its peering relationships could be costly and harmful to our business.
 
  We currently rely exclusively on Intermedia for network services. Prior to
the closing of this offering, we expect to enter into a two-year network
services agreement with Intermedia. For the term of this agreement, we will be
required to purchase, and Intermedia will be required to provide, at least 70%
of our non-peered network capacity requirements. If this agreement were to be
terminated, we would need to rapidly secure an alternative provider of these
services. Accordingly, we could incur transition costs and our monthly costs of
operations could increase. In addition, such a transition could have a
detrimental effect on our customer service levels.
 
  The Internet is composed of many ISPs that operate their own networks and
interconnect with other ISPs at various peering points. Peering relationships
are a competitive factor that allow some Web hosting companies to provide
faster data transmission than others. Intermedia's tier-one status and numerous
peering relationships enable it to provide us faster data transmission than
many other ISPs provide. Although Intermedia meets the industry's current
standards for peering, there can be no guarantee that other national ISPs will
maintain peering relationships with Intermedia. In addition, the requirements
associated with maintaining peering relationships with the major national ISPs
may change. We cannot assure you Intermedia will be able to expand or adapt its
network infrastructure to meet any new requirements on a timely basis or at
all.
 
If we do not respond effectively and on a timely basis to rapid technological
change and evolving industry standards, our business could suffer.
 
  Internet and networking technology is changing rapidly. Our future success
will depend largely on our ability to:
 
  .  offer services that incorporate leading technologies;
 
  .  address the increasingly sophisticated and varied needs of our current
     and prospective customers;
 
  .  respond to technological advances and emerging industry standards on a
     timely and cost-effective basis; and
 
  .  continue offering services that are compatible and interoperable with
     products, services and architectures of other vendors.
 
  Although we often work with various vendors in testing newly developed
products, there can be no assurance such products will be compatible with our
infrastructure or such products will adequately address
 
                                       12
<PAGE>
 
changing customer needs. Although we currently intend to support emerging
standards, there can be no assurance industry standards will be established or,
if they become established, that we will be able to conform to these new
standards in a timely fashion and maintain a competitive position in the
market. Our failure to conform to the prevailing standards, or the failure of
common standards to emerge, could harm our business. In addition, products,
services or technologies developed by others may render our services no longer
competitive or obsolete.
 
The growth of our business depends on the growth and performance of the
Internet.
 
  The increased use of the Internet for retrieving, sharing and transferring
information among businesses, consumers, suppliers and partners has only
recently begun to develop. Our success will depend on the continued growth in
Internet usage. Demand and market acceptance of the Internet are subject to a
high level of uncertainty and depend on a number of factors, including the
growth in consumer and business use of new interactive technologies, the
development of technologies that facilitate interactive communication between
organizations and targeted audiences, security concerns and increases in data
transport capacity. If the Internet as a commercial medium fails to grow or
develops more slowly than expected, then our business is unlikely to grow.
 
  The recent growth in the use of the Internet in general 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 ISPs and other organizations with links to
the Internet. Any perceived degradation in the performance of the Internet as a
whole could undermine the benefits of our services. The performance of our Web
site hosting services is ultimately limited by and relies on the speed and
reliability of the networks operated by third parties. Consequently, the
emergence and growth of the market for our services depends on improvements
being made to the entire Internet infrastructure to alleviate overloading and
congestion.
 
We may be unable to manage our anticipated growth effectively.
 
  Our future success depends in large part on our ability to manage the
anticipated growth in our business. For us to manage this growth, we will need
to:
 
  .  expand and enhance our operating and financial procedures and controls;
 
  .  replace or upgrade our operational and financial management information
     systems; and
 
  .  attract, train, manage and retain key employees.
 
  These activities are expected to place a significant strain on our financial
and management resources. If we are unable to manage growth effectively, our
business could suffer.
 
Our growth depends on our ability to expand data center capacity to meet
anticipated demand.
 
  Continuing to expand capacity is critical to achieving our business strategy.
This expansion is likely to include the need to add new hardware and software,
and may include the opening of additional data centers. We are currently
significantly expanding our data center capacity by constructing two new
facilities, one in Beltsville, Maryland, and another in San Jose, California to
augment our capacity in those regions. We intend to add data center capacity
over the next five years as justified by customer demand. Our ability to do so
successfully depends on:
 
  .  anticipating and planning for future demand levels;
 
  .  having access to sufficient capital; and
 
  .  locating and securing satisfactory data center sites and implementing
     the build-out of these sites, all of which may require significant lead
     time.
 
  If we cannot expand capacity effectively, our growth will suffer and we may
not be able to adequately meet the demands of existing customers.
 
                                       13
<PAGE>
 
We depend on our key personnel.
 
  Our success also depends in significant part on the continued services of our
key technical, sales and senior management personnel, including our President
and Chief Executive Officer, Nancy G. Faigen. Losing one or more of our key
employees could harm our business. In addition, we have recently hired a number
of key employees and officers, including our President and Chief Executive
Officer, and as a result, our entire management team has worked together for
only a brief time. We also have plans to hire additional executive management
personnel in the near future.
 
  We believe our short and long-term success depends largely on our ability to
attract and retain highly skilled technical, managerial and marketing
personnel, particularly additional management personnel in the areas of
application integration and technical support. Competition for such personnel
is intense. We may not be able to hire or retain the necessary personnel to
implement our business strategy, or we may need to pay higher compensation for
employees than we currently expect. Our inability to attract and retain such
personnel would limit our growth and harm our business.
 
Digex is controlled by Intermedia.
 
  Intermedia controls a majority of our voting power, and Intermedia's
interests in us may conflict with your interests as a stockholder. Intermedia,
through its wholly-owned subsidiary, Business Internet, owns all of the issued
and outstanding shares of our Class B Common Stock. When this offering is
completed, Intermedia will own     shares of Class B Common Stock. Each share
of Class B Common Stock is entitled to 10 votes, as compared to one vote for
each share of Class A Common Stock to be sold in this offering. Thus, after
this offering is completed, Intermedia will control approximately  % of the
voting power of Digex, and will be able to control the management and affairs
of Digex, and all matters submitted to our stockholders for approval, including
the election and removal of directors, and any merger, consolidation or sale of
all or substantially all of our assets. As a result, the price of our Class A
Common Stock may be affected.
 
  We may require additional funds to finance our business but our ability to
raise such funds is significantly limited by agreements that are binding on
Intermedia. Intermedia has issued debt securities to the public under seven
indentures. As a subsidiary of Intermedia, we are subject to a number of
restrictions under the Intermedia indentures. These restrictions will, among
other things, limit our ability to make certain restricted payments, incur
indebtedness and issue preferred stock, pay dividends or make other
distributions, engage in sale and leaseback transactions, create liens, sell
our assets, issue or sell our equity interests, or enter into certain mergers
and consolidations. As a result, our future financing sources will be
significantly limited and our use of any proceeds, including the net proceeds
of this offering, will be significantly restricted.
 
  We will be required to use all of the net proceeds of this offering to
purchase Telecommunications Related Assets within 270 days of this offering.
Telecommunications Related Assets mean assets used in connection with the
business of: (1) transmitting, or providing services relating to the
transmission of, voice, video or data through owned or leased transmission
facilities; (2) creating, developing of marketing communications related
network equipment, software and other devices for use relating to (1); or (3)
evaluating, participating in or pursuing any other activity or opportunity that
is related to those identified in (1) or (2); all as determined in good faith
by the board of directors of Intermedia. We will not be able to use the
proceeds of this offering directly to fund operating losses, working capital or
other uses that are not purchases of Telecommunications Related Assets. Because
we anticipate incurring operating losses and a significant need for working
capital for the foreseeable future, we expect that we will have to obtain funds
for such purposes from Intermedia or other sources. However, we are
significantly restricted as to the sources of funding that are available to us.
Prior to the closing of this offering, we will make arrangements with
Intermedia pursuant to which Intermedia will purchase from us, at our cost,
some of the Telecommunications Related Assets purchased with the net proceeds
of this offering. We expect to be able to use the proceeds of such sales of
telecommunications equipment to Intermedia for working capital purposes and to
fund operating losses. We believe that the net proceeds of this
 
                                       14
<PAGE>
 
offering should be sufficient to fund our capital needs into the second half of
2000. After that date, however, we will need to find sources of financing which
are likely to be significantly limited.
 
  We depend on Intermedia to fund our working capital and operating losses, but
Intermedia's ability to fund these needs is limited by its own substantial
indebtedness. Intermedia is and, after the offering, will continue to be highly
leveraged. At December 31, 1998, Intermedia had outstanding approximately $2.6
billion of debt and other liabilities (including trade payables), and
approximately $862.3 million of obligations with respect to four outstanding
series of preferred stock. The extent to which Intermedia is leveraged could
have a number of important consequences to you as our stockholder. We are, and
expect to continue to be, dependent on Intermedia for capital to fund our
working capital and operating losses. Intermedia's level of debt will require
it to dedicate a substantial portion of its future cash flow from operations
for payment of principal and interest on its debt, and dividends on and the
redemption of its preferred stock. Historically, Intermedia has not generated
sufficient cash flow to cover its operating and investing expenses. For the
year ended December 31, 1998, Intermedia's earnings were insufficient to cover
combined fixed charges and dividends on preferred stock. In addition, because
of the restrictions in the Intermedia indentures, Intermedia has only a limited
amount of cash that may be used for working capital purposes and to fund
operating losses. Consequently, Intermedia may not be able to provide us with a
source of funds for our working capital or operating losses.
 
  Our dependence on Intermedia and the degree to which Intermedia is leveraged
could have important consequences to our future operations, including but not
limited to:
 
  .  increasing our vulnerability to general adverse economic and industry
     conditions;
 
  .  limiting our ability to obtain additional financing to fund future
     working capital, operating losses, capital expenditures, acquisitions
     and other general corporate requirements;
 
  .  limiting our flexibility in reacting to changes in our business and the
     industry in which we compete; and
 
  .  placing us at a competitive disadvantage compared to better capitalized
     competitors.
 
  Our ability to issue additional capital stock is constrained by Intermedia's
ownership of the Class B Common Stock. In the future, Intermedia may elect to
sell shares of our Class B Common Stock that it controls to the public or to
distribute such shares to its own stockholders. If as a result of such sale or
distribution, Intermedia would no longer hold more than 50% of the total voting
power of our capital stock, the consent of the majority in principal amount of
the noteholders under the Intermedia indentures would be required for such a
sale or distribution. In addition, if we decide in the future to issue and sell
additional shares of our capital stock such that the voting power represented
by the Class B Common Stock held by Intermedia would no longer be greater than
50% of the total voting power of our capital stock, the consent of the majority
in principal amount of the noteholders under the Intermedia indentures would
also be required for such a sale. We would be free of the restrictions in the
Intermedia indentures only if Intermedia sold a sufficient number of its shares
of Digex to reduce its voting power below 50%.
 
  Digex does not have legal representation independent from Intermedia. Kronish
Lieb Weiner & Hellman LLP, counsel to Digex, is also counsel to Intermedia.
Consequently, Digex does not have legal representation independent from
Intermedia.
 
We are dependent on Intermedia for our general and administrative services.
 
  Intermedia has provided and is expected to continue to provide many of our
financial, administrative and operational services and related support
functions, including customer billing, legal, human resources, Year 2000
compliance and occasional network engineering. We have a General and
Administrative Services Agreement with Intermedia, as described under "Certain
Relationships--General and Administrative Services Agreement," to provide such
services over the next five years. Should Intermedia's provision of these
services no longer meet our needs or if Intermedia unexpectedly stops providing
these services for any reason, we could
 
                                       15
<PAGE>
 
face significant challenges and costs in transitioning to our own or
alternative general and administrative functions. Such a transition and any
resulting impairment of our operations could harm our financial results.
 
Regulatory and legal uncertainties could have significant costs or otherwise
harm our business.
 
  The law in the United States relating to the liability of on-line service
providers and ISPs for information carried on, disseminated through, or hosted
on their systems remains largely unsettled. Congress recently enacted the
"Digital Millennium Copyright Act," which became effective in October 1998. The
Digital Millennium Copyright Act includes a limitation on liability of on-line
service providers for copyright infringement for transmitting, routing, or
providing connections, transient storage, caching or storage at the direction
of a user. This limitation on liability applies if the service provider had no
actual knowledge or awareness that the transmitted or stored material was
infringing and if certain other conditions are met. See "Business--Government
Regulation." Since this law is new, we are unsure of how it will be applied to
limit any liability we may face in the future for any possible copyright
infringement or copyright-related issues. This new law also requires ISPs to
follow certain "notice and take-down" procedures in order to be able to take
advantage of the limitation on liability. We have not yet implemented such
procedures nor evaluated the cost of complying with them. Although our
customers are subject to an acceptable use policy which regulates their use of
our services, this policy and any enforcement of it may not be sufficient to
shield us from liability under the Digital Millenium Copyright Act or
otherwise.
 
  In addition, this new law addresses only copyright infringement. It may take
years to determine whether and how existing laws such as those governing other
types of intellectual property (such as trademarks), privacy, libel and
taxation apply to the Internet. If liability for materials carried on or
disseminated through their systems is imposed on ISPs, we would likely
implement measures to reduce our exposure to such liability. Such measures
could require us to expend substantial resources or discontinue certain product
or service offerings. In addition, increased attention to liability issues, as
a result of lawsuits, legislation and legislative proposals, could divert
management attention, result in unanticipated expenses and harm our business.
 
  The growth and development of the market for on-line commerce may prompt
calls for more stringent consumer protection laws, both in the United States
and abroad, that may impose additional burdens on companies conducting business
on-line. The adoption or modification of laws or regulations relating to the
Internet could adversely affect our business.
 
  We are not currently subject to direct regulation by the Federal
Communications Commission ("FCC") or any other government agency, other than as
to regulations applicable to business in general. However, in the future we may
be subject to regulation by the FCC or other federal or state agencies. Our
costs could increase and our business could suffer depending on the extent to
which our activities might be regulated.
 
Our business plan contemplates future international operations but there are
numerous risks and uncertainties in offering services outside of the United
States.
 
  We intend to expand into international markets and may build data centers
internationally. We cannot be sure that we will be able to successfully sell
our services or adequately maintain operations outside the United States. In
addition, there are certain risks inherent in conducting business
internationally. These include:
 
  .  unexpected changes in regulatory requirements;
 
  .  tariffs and other trade barriers;
 
  .  ability to secure and maintain the necessary physical and
     telecommunications infrastructure;
 
  .  challenges in staffing and managing foreign operations;
 
  .  differing technology standards;
 
  .  employment laws and practices in foreign countries;
 
  .  political instability;
 
                                       16
<PAGE>
 
  .  longer payment cycles and problems in collecting accounts receivable;
 
  .  fluctuations in currency exchange rates and imposition of currency
     exchange controls; and
 
  .  potentially adverse tax consequences.
 
  Any of these could adversely affect our international operations.
Furthermore, some foreign governments have enforced laws and regulations on
content distributed over the Internet that are more restrictive than those
currently in place in the United States. Any one or more of these factors could
adversely affect our contemplated future international operations and,
consequently, our business.
 
We may be unable to protect our intellectual property rights or to continue
using intellectual property that we license from others.
 
  We rely on a combination of copyright, trademark, service mark and trade
secret laws and contractual restrictions to establish and protect certain of
our proprietary rights. We have no patented technology that would bar
competitors from our market. Despite our efforts to protect our proprietary
rights, unauthorized parties may attempt to copy or otherwise obtain and use
our data or technology, such as our customized Digex Centralized Nervous System
applications.
 
  We also rely on certain technologies licensed from third parties. We cannot
be sure these licenses will remain available to us on commercially reasonable
terms or at all. The loss of such technology could require us to obtain
substitute technology of lower quality or performance standards or at greater
cost, which could harm our business.
 
We could lose revenues and our reputation may be damaged if our systems or
those of our customers are not Year 2000 compliant.
 
  Many currently installed computer systems and software products are coded to
accept only two-digit entries in the date code field. These date code fields
will need to accept four-digit entries in order for 20th century dates to be
distinguished from 21st century dates. As a result, before the end of this
year, computer systems and software used by many companies may need to be
upgraded to comply with these "Year 2000" requirements. Non-compliant systems
may cause miscalculations which will interfere with business activities or
simply fail to work at all.
 
  We have made arrangements with Intermedia for Year 2000 compliance services.
Under these arrangements, we have implemented a Year 2000 program intended to
ensure our computer systems and applications will function properly beyond
1999. We are continuing to study and resolve many of the Year 2000 issues which
could affect us. However, we cannot be sure that we will be able to promptly or
correctly address all the Year 2000 issues that could affect our systems,
especially where third parties are involved. Although we have requested
assurances from our suppliers that their products are Year 2000 compliant, not
every supplier has responded to our request. Despite the assurances we have
received, some of our suppliers' products and services could still fail and
affect our operations in unpredictable ways. If we cannot achieve Year 2000
compliance, our systems could be disrupted for a period of time. This would
cause a loss of revenues, including requests from customers for credits for
downtime. More importantly, any significant disruption would seriously damage
our business reputation. We might also face lawsuits for damages.
 
  Additionally, we cannot evaluate our customers' Year 2000 readiness. We
believe that we are not responsible for the Year 2000 compliance of our
customers' Web sites and we intend to notify them in writing of this fact and
to urge them to ensure that their sites are Year 2000 compliant. Some of our
customers' sites may fail due to Year 2000 issues and, while we believe that
the failure of any one customer's site will not affect other customers' sites
or our network, we cannot guarantee that this will be the case. Also, to the
extent that a customer's site is not functioning correctly and it is not
possible to determine that the malfunctioning is caused by the customer's
software, the customer may request service credits or we might otherwise have a
difficult time realizing the expected revenues from such a customer.

  Our statements regarding the Year 2000 issue are forward-looking statements
subject to a significant number of risks and uncertainties. While we have
attempted to reasonably evaluate the Year 2000 risks that we face, these risks
include many factors which are beyond our control and we cannot be sure of the
type or extent of damages that we might experience. The worst-case scenario
related to the Year 2000 issue would be an overall failure of the national
Internet and telecommunications infrastructure and the electrical grid. If this
happened, we would be unable to serve our customers for a period of time. Any
national disruption to these systems would have unpredictable and potentially
severe impacts on our business and financial condition.
 
  We strongly urge you to read about our Year 2000 efforts in this prospectus
under the heading "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Impact of Year 2000."
 
There has been no prior market for our Class A Common Stock and the market
price of the shares will fluctuate.
 
  There has not been a public market for the Class A Common Stock. We cannot be
sure that an active public market for the Class A Common Stock will develop or
continue after this offering. Prices for the Class A Common Stock will be
determined in the marketplace and may be influenced by many factors, including
variations in our financial results, changes in earnings estimates by industry
research analysts, investors' perceptions of us and general economic, industry
and market conditions. The initial public offering price per share of the Class
A Common Stock has been determined by negotiations among us and the
representatives of the underwriters. Investors may not be able to sell their
Class A Common Stock at or above the initial public offering price.
 
  We believe there are relatively few comparable companies that have publicly
traded equity securities. This may also affect the trading price of the Class A
Common Stock after this offering and make it more difficult for you to evaluate
the value of the Class A Common Stock.
 
  The market price of the shares of Class A Common Stock is likely to be highly
volatile and could be subject to wide fluctuations in response to, among other
things, the following factors:
 
  .  actual or anticipated variations in our results of operations;
 
  .  announcements of technological innovations;
 
  .  new products or services introduced by us or our competitors;
 
  .  changes in financial estimates by securities analysts;
 
  .  conditions and trends in the Internet;
 
  .  acquisitions or strategic alliances involving us, our competitors, our
     suppliers or our customers; and
 
  .  general market conditions and other factors.
 
  Further, the stock markets, and in particular the Nasdaq National Market,
have experienced extreme price and volume fluctuations that have particularly
affected the market prices of equity securities of many technology companies
and that often have been unrelated or disproportionate to the operating
performance of such companies. The trading prices of many technology companies'
stocks are at or near historical highs and reflect price to earnings ratios
substantially above historical levels. There can be no assurance these trading
prices and price to earnings ratios will be sustained. These broad market
factors may adversely affect the market price of our Class A Common Stock.
These market fluctuations, as well as general economic, political and market
conditions such as recessions, interest rates or international currency
fluctuations, may adversely affect the market price of the Class A Common
Stock. In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted against such companies. Such litigation, if instituted, could result
in substantial costs and a diversion of management's attention and resources,
which could harm our business.

Future sales of our common stock could adversely affect the price of the Class
A Common Stock.
 
  After this offering is completed,     shares of Class A Common Stock will be
issued and outstanding, assuming no exercise of the underwriters' over-
allotment option. All of the shares of Class A Common Stock sold in this
offering will be freely tradable under the Securities Act unless purchased by
our "affiliates," as that term is defined in the Securities Act. In connection
with this offering, our officers and directors and some of our stockholders
will be required to refrain from selling any shares of Common Stock for a
period of     days after the date of this prospectus without the written
consent of     . We cannot be sure what effect, if any, future sales of shares
or the availability of shares for future sale will have on the market price of
the Class A Common Stock. The market price of our Class A Common Stock could
drop due to sales of a large number of shares of our Class A Common Stock in
the market after this offering or the perception that such sales could occur.
These factors could also make it more difficult to raise funds through future
offerings of Common Stock.
 
You will suffer immediate and substantial dilution.
 
  Purchasers of the Class A Common Stock being offered will experience
immediate and substantial dilution in the net tangible book value of their
Class A Common Stock. See "Dilution."
 
Some provisions of the Delaware Anti-Takeover Law and of our certificate of
incorporation and bylaws could discourage a takeover of Digex and adversely
affect the price of the Class A Common Stock.
 
  Upon completion of this offering, our board of directors will have the
authority to issue up to     shares of preferred stock and to determine the
price, rights, preferences, privileges and restrictions, including voting
rights, of those shares without any further vote or action by the stockholders.
The rights of the holders of any of our common stock will be subject to, and
may be adversely affected by, the rights of the holders of any preferred stock
that may be issued in the future. The issuance of preferred stock, while
providing flexibility in connection with possible acquisitions and other
corporate purposes, could have the effect of making it more difficult for a
third party to acquire a majority of our outstanding voting stock. We have no
current plans to issue shares of preferred stock. We are also subject to
certain provisions of Delaware law which could have the effect of delaying,
deterring or preventing a change in control of Digex, including Section 203 of
the Delaware General Corporation Law, which prohibits a Delaware corporation
from engaging in any business combination with any interested stockholder for a
period of three years from the date the person became an interested stockholder
unless certain conditions are met. In addition, our certificate of
incorporation and bylaws contain certain provisions that, together with
Intermedia's ownership of Class B Common Stock, which is entitled to 10 votes
per share, could discourage potential takeover attempts and make attempts by
stockholders to change management more difficult, which could adversely affect
the market price of our Class A Common Stock.
 
This prospectus includes forward-looking statements which could differ from
actual future results.
 
  Some of the statements in this prospectus that are not historical facts are
"forward-looking statements." Forward-looking statements can be identified by
the use of words such as "estimates," "plans," "anticipates," "expects,"
"intends," "believes" or the negative thereof or other variations thereon or by
discussions of strategy that involve risks and uncertainties. Examples of
forward-looking statements include discussions relating to:
 
  .  plans to expand our existing Web site hosting services and applications
     for enterprises doing business on the Internet;
 
  .  introductions of new products and services;
 
  .  proposals to build new data centers in various geographic areas;
 
  .  estimates of market sizes and addressable markets for our services and
     products;
 
  .  anticipated revenues from designated markets during 1999 and later
     years; and
 
                                       19

  .  statements regarding the future course of our relationship with
     Intermedia.
 
  We wish to caution you that all the forward-looking statements contained in
this prospectus are only estimates and predictions. Our actual results could
differ materially from those anticipated in the forward-looking statements due
to risks, uncertainties or actual events differing from the assumptions
underlying these statements. Such risks, uncertainties and assumptions include,
but are not limited to, those discussed in this prospectus.

                                USE OF PROCEEDS
 
  We estimate the net proceeds from the sale of the     shares of Class A
Common Stock we are offering will be approximately $     million, at an assumed
initial public offering price of $    per share and after deducting the
estimated underwriting discounts and commissions and estimated offering
expenses. If the underwriters' over-allotment option is exercised in full, we
estimate such net proceeds will be approximately $    million. The principal
purposes of this offering are to obtain additional capital, create a public
market for our Class A Common Stock and facilitate our future access to the
public capital markets.
 
  Under the terms of Intermedia's indentures, described under "Risk Factors--
Digex is controlled by Intermedia," we will be required to use all of the net
proceeds of this offering to purchase Telecommunications Related Assets. We
intend to use approximately $    of the net proceeds to continue to expand and
enhance our data center infrastructure. We expect that some of the remaining
Telecommunications Related Assets, which we will be required to purchase, will
be sold to Intermedia at our costs. We expect to be able to use the proceeds of
such sales to Intermedia for working capital purposes and to fund our operating
losses. The amounts actually expended for such capital expenditures and working
capital purposes may vary significantly, depending on a number of factors,
including our future revenues and Intermedia's availability of funds.
 
  A portion of the net proceeds may also be used to acquire or invest in
complementary businesses, technologies, product lines or products. We have no
current plans, agreements or commitments with respect to any such acquisition,
and we are not currently engaged in any negotiations with respect to any such
transaction. Pending use of the net proceeds of this offering, we intend to
invest the net proceeds in short-term, interest-bearing, investment grade
securities.
 
                                DIVIDEND POLICY
 
  We do not anticipate paying any dividends on any of our common stock in the
foreseeable future. Moreover, because we are subject to restrictions under the
Intermedia indentures, we are effectively prohibited from paying dividends. We
may also incur indebtedness in the future which may prohibit or effectively
restrict the payment of dividends.

expenses that we will pay and the application of the estimated net proceeds
from this offering. This table should be read in conjunction with the financial

                                    DILUTION
 
  Our net tangible book value as of     , 1999 was approximately $    million,
or $    per share of Class A and Class B Common Stock. Pro forma net tangible
book value per share represents the amount of total tangible assets less total
liabilities, divided by the pro forma number of shares of Class A Common Stock
and Class B Common Stock outstanding as of     , 1999. After giving effect to
the issuance and sale of the     shares of Class A Common Stock offered hereby
at an assumed initial public offering price of $    per share and after
deducting estimated underwriting discounts and commissions and estimated
offering expenses, our pro forma net tangible book value as of     , 1999 would
be $    million, or $    per share. This represents an immediate increase in
pro forma net tangible book value of $    per share to existing stockholders
and an immediate dilution of $    per share to new investors. The following
table illustrates this per share dilution:

                            SELECTED FINANCIAL DATA
 
  The following table sets forth selected historical financial information of
Digex for the period from July 7, 1997 (date of acquisition) to December 31,
1997 and the year ended December 31, 1998, and of the Predecessor for the year
ended December 31, 1996 and the period from January 1, 1997 to July 6, 1997.
The selected historical financial information has been derived from Digex's and
the Predecessor's financial statements which have been audited by Ernst & Young
LLP and are included elsewhere in this prospectus.
 
  The following table also sets forth our pro forma financial information for
the year ended December 31, 1997. The pro forma financial information gives
effect to the purchase by Intermedia of Business Internet as if such
acquisition had occurred on January 1, 1997, but only includes financial
information for the Predecessor. The presentation of pro forma financial
information was made to permit useful comparison of results of operations
between periods presented. This pro forma financial information is not
necessarily indicative of the operating results we would have achieved if the
Predecessor had been acquired on January 1, 1997. The relationship between
Business Internet and the Predecessor is more fully described in note 1 to the
financial statements.
 
  You should read the selected financial data below in conjunction with our
audited financial statements and the related notes and the Predecessor's
audited financial statements included elsewhere in this prospectus. You should
also read the accompanying "Management's Discussion and Analysis of Financial
Condition and Results of Operations," also contained later in this prospectus.

(3) EBITDA before certain charges consists of earnings (loss) before tax
    benefit, depreciation and amortization and the charge off of purchased in-
    process research and development. EBITDA, before certain charges, does not
    represent funds available for management's discretionary use and is not
    intended to represent cash flow for operations. EBITDA before certain
    charges should be considered only as an alternative to net loss as an
    indication of operating performance or cash flows as a measure of
    liquidity.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the financial
statements and notes relating to those statements appearing elsewhere in this
prospectus.
 
Overview
 
  Digex is a leading provider of Internet hosting services to businesses and
institutions implementing complex, interactive Web sites and Web-based
applications. Our offerings include Web site and application hosting,
enterprise and consulting services. From major corporations to Internet start-
ups, our clients leverage our services to rapidly and cost-effectively deploy
secure and reliable business solutions including on-line banking, on-line
procurement and electronic retailing. We provide the computer hardware,
software, network technology, and systems management necessary to offer our
customers comprehensive outsourced Web site hosting solutions.
 
  We believe our singular focus on delivering mission-critical Web site and
application hosting solutions has been the major contributor to our growth.
Digex currently provides hosting services to over 550 customers, including
American Century Investments, Budget Rent-A-Car, Forbes, J. Crew, Kraft,
Universal Studios and Nike. We operate two state-of-the-art data centers
strategically positioned on the east and west coasts of the United States. In
these data centers, we house over 1,300 Windows NT and UNIX-based servers which
we own and manage. Our revenues have grown at a compounded annual growth rate
of 184% over the past two years from $2.8 million in 1996 to $22.6 million in
1998. The following are among the key factors that we believe will continue to
drive our growth:
 
  .  a highly scalable operating platform which was designed to facilitate
     the rapid, cost-efficient implementation and expansion of customers' Web
     site hosting initiatives;
 
  .  an experienced management team and technical experts, who in the
     aggregate hold over 200 technical certifications from leading companies
     such as Cisco Systems, Microsoft and Sun Microsystems;
 
  .  a highly skilled research and development organization dedicated to
     identifying the best available tools, technologies and processes;
 
  .  a growing, geographically distributed direct sales force; and
 
  .  a network of over 120 business partnership alliances which provide
     complementary design, development and integration services for our
     customers and which represent a significant source of new customer
     referrals for Digex.
 
  We offer a full range of complementary value-added services designed to
handle the rapidly evolving requirements of complex Web sites. Our services
include the following:
 
  .  Web site management services;
 
  .  integrated business solutions;
 
  .  enterprise services; and
 
  .  consulting services.
 
  Our business started in 1996, as the Web site hosting unit (the
"Predecessor") of Business Internet Inc. (previously known as DIGEX,
Incorporated), a company that was principally an Internet access and Web site
hosting services provider. Business Internet (at the time known as DIGEX,
Incorporated) went public in October 1996, and was acquired by Intermedia in
July 1997. In contemplation of this offering, we were incorporated as Digex,
Incorporated on April 27, 1999. On that date, Business Internet contributed our
assets to the newly formed Digex, Incorporated in order to effect a
recapitalization of our business. As of the date of this prospectus, Business
Internet, a wholly-owned subsidiary of Intermedia, owns 100% of our common
stock.
 
                                       26
<PAGE>
 
  Revenue. Our revenues consist primarily of monthly fees from sales of our Web
site hosting and other related services. Contracts for these services are
typically between one and three years in length. In addition to Web hosting, we
have also recently begun to offer integrated business solutions, enterprise
services and consulting services and believe that we will begin to derive
increasing amounts of revenues from the sale of these services in the future.
 
  Cost and Expenses. Cost and expenses include:
 
    .cost of operations;
 
    .cost of services;
 
    .selling, general and administrative expenses; and
 
    .depreciation and amortization expense.
 
  Cost of operations consist primarily of the costs for our network
connectivity. We expect our network connectivity requirements to grow in
conjunction with the growth of our overall business and accordingly expect
these costs to increase in the future.
 
  Cost of services consist principally of salaries and benefits for our
technical operations and customer service personnel and facilities
administration, including rent, maintenance and utilities to support our data
centers. We expect our cost of services to increase in dollar amount but to
decline as a percentage of revenue due to economies of scale and expected
improvements in technology and productivity.
 
  Selling, general and administrative expenses consist primarily of salaries
and benefits for our marketing, sales and support personnel, advertising costs,
consultant's fees and other miscellaneous expenses including travel and
entertainment expenses. We expect selling, general and administrative expenses
in the future to increase in dollar amount but to decline as a percentage of
revenue.
 
  Depreciation and amortization expense consists primarily of depreciation of
our data center equipment and related assets and amortization of our intangible
assets. We expect these expenses to increase due to our plans to invest
significant capital to expand our data center capacity.

Results of Operations
 
  The following table presents certain information derived from the audited
financial statements for the years ended December 31, 1996 and 1998 expressed
as a percentage of revenue. For the purposes of the following discussion and
analysis, the results of operations of the Predecessor for the period from
January 1, 1997 to July 6, 1997, have been adjusted to reflect the acquisition
of Business Internet by Intermedia as if the acquisition had occurred at the
beginning of 1997 and have been combined with the results of our operations for
the period from July 7, 1997 (date of acquisition) to December 31, 1997. This
computation was done to permit useful, complete year comparisons between the
results for 1996, 1997 and 1998. However, this pro forma information is not
necessarily indicative of the operating results we would have achieved if the
Predecessor had been acquired on January 1, 1997.

Year Ended December 31, 1998 Compared to Pro Forma Year Ended December 31, 1997
 
  Revenue. Revenues were $22.6 million for the year ended December 31, 1998
compared to $11.6 million for the year ended December 31, 1997, an increase of
94.9%. The $11.0 million increase in revenue was a result of our increased
marketing efforts, and market acceptance of our new products, resulting in
growth in our number of customers. We also experienced increases in revenue
from existing customers through upgrades and value added services. This
translated into higher average revenues per server. Additionally, during 1998
we increased the number of quota-bearing sales representatives.
 
  Cost of Operations. Our cost of operations was $6.7 million for the year
ended December 31, 1998, compared to $2.8 million for the year ended December
31, 1997. The $3.9 million increase was due to increased network capacity
requirements necessary to support our growing business. In addition, we also
experienced an increase in the average network bandwidth per server. As a
percentage of revenue, the cost of operations increased to 29.6% in 1998 from
24.2% in 1997 primarily as a result of our purchasing added capacity per server
in 1998 as compared to 1997 to improve customer Web site performance.
 
  Cost of Services. Our cost of services was $7.0 million for the year ended
December 31,1998, compared to $3.4 million for the year ended December 31,
1997. The $3.6 million increase was due primarily to the hiring of additional
engineering and operations staff to support our expanded customer base. As a
percentage of revenue, the cost of services increased to 31.1% in 1998 from
29.5% in 1997.
 
  Selling, General and Administrative. Expenses increased to $17.5 million for
the year ended December 31, 1998, compared to $13.1 million for the year ended
December 31, 1997. The $4.4 million increase was due
 
                                       28
<PAGE>
 
to higher commission expenses associated with our increased sales levels as
well as increases in our administrative headcount. As a percentage of revenue,
the expenses decreased to 77.5% in 1998 from 112.7% in 1997 due to economies of
scale.
 
  Depreciation and Amortization. Depreciation and amortization increased to
$8.1 million for the year ended December 31, 1998, compared to $4.9 million for
the year ended December 31, 1997. The $3.2 million increase was largely due to
increased capital expenditures for servers and other data center related
equipment.
 
  Income Tax Benefit. Our income tax benefit decreased to $159,000 for the year
ended December 31, 1998, compared to $4.7 million for the year ended December
31, 1997. The 1998 income tax benefit represents the recognition of a portion
of the benefits associated with 1998 tax net operating loss carryforwards.
Benefits were recognized in 1998 to the extent of unused deferred tax credits
originating in previous periods.
 
  Net Loss. Net losses decreased to $(16.6) million for the year ended December
31, 1998, compared to $(22.9) million for the year ended December 31, 1997.
 
Pro Forma Year Ended December 31, 1997 Compared to the Year Ended December 31,
1996
 
  Revenue. Revenues were $11.6 million for the year ended December 31, 1997,
compared to $2.8 million for the year ended December 31, 1996, an increase of
314%. The $8.8 million increase in revenue was due primarily to our increased
marketing and sales efforts and the increased market acceptance of dedicated
Web site hosting as a viable outsourcing solution.
 
  Cost of Operations. Our cost of operations was $2.8 million for the year
ended December 31, 1997, compared to $2.0 million for the year ended December
31, 1996. The $806,000 increase was due to increased network connectivity
expenses in connection with the growth in the number of managed servers. This
increase in our cost of operations was partially offset by the more favorable
network connectivity pricing we received subsequent to Intermedia's acquisition
of Business Internet in July 1997. As a percentage of revenue, the cost of
operations declined to 24.2% in 1997 from 71.4% in 1996 primarily as a result
of the favorable pricing from Intermedia.
 
  Cost of Services. Our cost of services was $3.4 million for the year ended
December 31, 1997, compared to $684,000 for the year ended December 31, 1996.
The $2.7 million increase was due primarily to headcount increases in customer
service and operations during 1997. As a percentage of revenue, the cost of
services increased to 29.5% in 1997 from 24.4% in 1996, primarily due to the
additional customer service and operations employees who were hired in
conjunction with the expansion of our marketing efforts to support the
anticipated growth in our business.
 
  Selling, General and Administrative. Expenses increased to $13.1 million for
the year ended December 31, 1997, compared to $3.2 million for the year ended
December 31, 1996. The $9.9 million increase was due to significant increases
in headcount in our sales, marketing, management information, and
administration departments, as well as one time expenditures for employee
recruitment, relocation, and training. As a percentage of revenue, the expenses
decreased to 112.7% in 1997 from 114.0% in 1996.
 
  Depreciation and Amortization. Depreciation and amortization increased to
$4.9 million for the year ended December 31, 1997, compared to $591,000 for the
year ended December 31, 1996. The $4.3 million increase was due to the
amortization of intangible assets in connection with the purchase of Business
Internet as allocated to us. This increase was also due to increased capital
expenditures for servers and other data center related equipment connected with
the continued expansion of our business.
 
  Charge off of Purchased In-Process Research and Development. The charge for
purchased in-process research and development of $15.0 million in 1997
represents the amount of purchased in-process research and development
associated with the purchase of Business Internet by Intermedia. In connection
with this
 
                                       29
<PAGE>
 
acquisition, Intermedia allocated $15.0 million of the purchase price to in-
process research and development projects that relate directly to us. This
allocation represents the estimated fair value based on risk-adjusted cash
flows related to the incomplete products. At the date of acquisition, the
development of these projects had not yet reached technological feasibility and
the in-process research and development had no alternative future uses.
Accordingly, these costs were expensed as a one-time charge to earnings in
1997.
 
  Income Tax Benefit. Our income tax benefit increased to $4.7 million for the
year ended December 31, 1997, compared to $0 for the year ended December 31,
1996. The income tax benefit in 1997 results from our ability to recognize the
benefits of our 1997 net tax operating loss carryforward to the extent of
available and unused tax credits that arose in connection with Intermedia's
purchase of Business Internet. Such tax credits relate to the purchase
accounting differences between bases in our identifiable intangible assets.
 
  Net Loss. Net losses decreased to $(22.9) million for the year ended December
31, 1997, compared to $(3.7) million for the year ended December 31, 1996.
 
Liquidity and Capital Resources
 
  We have used cash in our operating and investing activities during all
periods since inception. These cash usages have been funded by permanent
contributions to capital. Such contributions amounted to $24.5 million and
$41.9 million in 1997 and 1998, respectively.
 
  Net cash used in operating activities in 1996, 1997 and 1998 was $2.6
million, $13.3 million and $10.9 million, respectively. Net cash used for
operating activities in each of these periods was primarily the result of
operating losses, offset in part by increases in accounts payable and accrued
expenses.
 
  Net cash used for investing activities in 1996, 1997 and 1998 was $1.4
million, $56.2 million and $30.9 million, respectively. Net cash used for
investing activities in each of these periods was primarily the result of
capital expenditures for data center infrastructure, as well as leasehold
improvements, furniture and fixtures and computers and other equipment.
Additionally, in July of 1997, goodwill and other intangible assets were
allocated to us for separate reporting purposes, and shown as a use of cash.
Although we have plans to invest significantly in property and equipment, we
have no material commitments for such items at this time.
 
  Our operating activities are expected to result in uses of cash for several
years, as we expand our data center capacity, increase our headcount in support
of such operations and invest in our marketing organization. In addition, we
expect to invest significantly in the purchase of property and equipment. Our
management believes that the proceeds of this offering will be sufficient to
meet our projected cash needs into the second half of 2000. We intend to seek
funding from external sources to meet our cash needs subsequent to that date.
There can be no assurance that such funding will be available on terms
satisfactory to us. Alternatively, Intermedia could advance funds to us to meet
our requirements after that date, but it has no obligation to do so.
 
Impact of Year 2000
 
  The Year 2000 issue is the result of computer-controlled systems using two
digits rather than four to define the applicable year. For example, computer
programs that have time-sensitive software may recognize a date ending in "00"
as the year 1900 rather than the year 2000. This could result in system failure
or miscalculations causing disruptions of operations including, among other
things, a temporary inability to process transactions, send invoices, or engage
in similar normal business activities. To ensure that our computer systems and
applications will function properly beyond 1999, through Intermedia, we have
implemented a Year 2000 program.
 
                                       30
<PAGE>
 
Project and State of Readiness
 
  We have developed a five-phase plan that is designed to assess the impact of
the Year 2000 issue on its information technology ("IT") and non-information
technology ("Non-IT"). This table represents management's best estimates of our
progress as of March 31, 1999 and expected dates of completion with respect to
our mission-critical and non-mission-critical systems:

</TABLE>
 
  Because it is not always necessary to complete one phase prior to completing
the next, some projects within a given phase have been started, while there may
be outstanding tasks associated with prior phases. Priority is always placed on
mission critical systems.
 
 Phase I Preliminary Activity
 
  This phase is a phase of awareness and education. The outcome of this phase
was our understanding of the criticality, risks, size and scope of the Year
2000 problem.
 
 Phase II Problem Determination
 
  In this phase we performed an inventory and assessment to determine which
portions of our hardware and software would have to be replaced or modified in
order for our networks, office equipment and information management systems to
function properly after December 31, 1999. Such determinations were based in
part on representations made by hardware and software vendors as to the Year
2000 compliance of the systems we use. However, there can be no assurances that
any vendor representations received by us were accurate or complete. We also
conducted a risk assessment to identify those systems whose failure would be
expected to result in the greatest risk to our business. As of March 31, 1998,
Phase II of the plan was 100% complete with respect to IT and 100% complete
with respect to Non-IT. However, there can be no assurances that mission
critical equipment has not been overlooked.
 
 Phase III Plan Complete & Resources Committed
 
  During Phase III, we designed a plan to make the necessary modifications to
and/or replace the impacted software and hardware and committed the resources
towards the completion of such a plan. While we believe we have almost
completed our plan for achieving Year 2000 compliance, the discovery of
additional IT or Non-IT systems requiring remediation could adversely impact
the current plan and the resources required to implement the plan.
 
 Phase IV Operational Sustainability
 
  We are actively engaged in Phase IV, using both internal and external
resources to reprogram, or replace, and test certain components of our networks
and information processing systems for Year 2000 compliance and scheduling the
installation of other necessary hardware and software upgrades. Although we
intend to conduct tests to ensure the equipment is Year 2000 compliant, we will
focus primarily on those systems whose failure would pose the greatest risks to
our operations. There can be no assurance that we have not overlooked mission
critical IT or Non-IT systems. We will not likely test all of our equipment and
will rely upon vendor
 
                                       31
<PAGE>
 
representations, if received, where tests are not conducted. There can be no
assurance that any vendor representation will be accurate or complete. As of
March 31, 1999, Phase IV of the plan was 50% complete for IT and 50% for Non-
IT. We expect to complete Phase IV by September 30, 1999.
 
 Phase V Fully Compliant
 
  We plan to be fully compliant on mission-critical components no later than
September 30, 1999, which is prior to any anticipated impact on our operating
systems. Though the majority of the work will be completed by early third
quarter 1999, there are elements that will not be completed (Phase V) until
late in the third quarter of 1999 primarily due to limited availability of
compliant software and hardware and prioritization of mission critical systems.
As of March 31, 1999, we estimate that our remediation efforts are
approximately 50% complete overall.
 
  We believe that we have allocated adequate resources for this purpose and
expect our Year 2000 date conversion program to be successfully completed on a
timely basis. However, there can be no assurance that it will successfully
implement all of the necessary upgrades in a timely manner. We presently
believe that with modifications to existing software and conversions to new
software and hardware, the Year 2000 issue will not pose significant
operational programs for our systems or have any adverse impact on our
customers or business units. However, if such modifications and conversions are
not made, or are not completed in a timely fashion, the Year 2000 problem could
harm our reputation and business.
 
Costs
 
  We have tracked Year 2000 costs on a company-wide basis by segregating our
internal and external costs and hardware and software costs. The internal costs
are comprised of employee hours, and external costs are comprised of outside
consultant costs.
 
  The cost estimates presented below do not include system upgrades that would
otherwise result as part of our capital expenditure program. The estimated
costs of the project and the date which we have established to complete the
Year 2000 modifications are based on management's best estimates, which were
derived utilizing numerous assumptions of future events, including the
continued availability of certain resources, third party modification plans and
other factors. However, there can be no guarantee that these estimates will be
achieved and actual results could differ materially from those anticipated.
Specific factors that might cause such material differences include, but are
not limited to, the availability and cost of personnel trained in this area,
the ability to locate and correct all relevant computer codes, unanticipated
mergers and acquisitions, and similar uncertainties.
 
  A summary of historical and estimated costs for the Year 2000 project are
listed below:

        Total.................................................    $1,220,000
</TABLE>
 
Risks and Contingency Plan
 
  While we are working to test our own mission-critical systems for Year 2000
compliance, we do not control the systems of our suppliers. We are currently
seeking assurance from our suppliers and strategic business partners regarding
the Year 2000 readiness of their systems. We are currently planning
interoperability tests to ensure that our suppliers' and business partners'
systems will accurately interact with our systems into and beyond the Year
2000. Importantly, we are relying on Intermedia's Year 2000 compliance efforts
to ensure
 
                                       32
<PAGE>
 
that our connectivity with Intermedia is available after December 31, 1999.
Notwithstanding any measures we may take, there is some risk that the
interaction of our systems and those of our suppliers or business partners may
be impacted by the Year 2000 date change. In addition, in light of the vast
interconnection and interoperability of telecommunications networks and the
Internet worldwide, to provide services to our customers is dependent in large
part on the networks and systems of other carriers. To the extent the networks
and systems of those carriers are adversely impacted by Year 2000 problems, our
ability to service our customers may be adversely impacted as well. Any such
impact could have a material adverse effect on our operations.
 
  The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations. Such failures could materially and adversely affect the company's
results of operations, liquidity and financial condition. Due to the general
uncertainty inherent in the Year 2000 problem, resulting in part from the
uncertainty of the Year 2000 readiness of third-party suppliers and customers,
we are unable to determine at this time whether the consequences of Year 2000
failures will have a material impact on our results of operations, liquidity or
financial condition. The Year 2000 project is expected to significantly reduce
our level of uncertainty about the Year 2000 problem and, in particular, about
the Year 2000 compliance and readiness of our material suppliers and business
partners. We believe that, with the implementation of new business systems and
completion of the Year 2000 project as scheduled, the possibility of
significant interruptions of normal operations should be reduced.
 
  In a recent Securities and Exchange Commission release regarding Year 2000
disclosure, the Securities and Exchange Commission stated that public companies
must disclose the most reasonably likely worst case Year 2000 scenario.
Although it is not possible to assess the likelihood of any of the following
events, each must be included in a consideration of worst case scenarios:
widespread failure of electrical, gas, and similar supplies serving us,
widespread disruption of the services provided by common communications
carriers; similar disruption to the means and modes of transportation for us
and our employees, contractors, suppliers and customers; significant disruption
to our ability to gain access to, and remain working in, office buildings and
other facilities; the failure of substantial numbers of our critical computer
hardware and software systems, including both internal business systems and
systems controlling operational facilities such as electrical generation,
transmission and distribution systems; and the failure of outside entities'
systems, including systems related to banking and finance. We urge you to read
"Risk Factors--We could lose revenues and our reputation may be damaged if our
systems or those of our customers are not Year 2000 compliant."
 
 
  If we cannot operate effectively after December 31, 1999, we could, among
other things, face substantial claims by customers or loss of revenue due to
service interruptions, inability to fulfill contractural obligations or bill
customers accurately and on a timely basis, and increased expenses associated
with litigation, stabilization of operations following critical system failures
and the execution of contingency plans. We could also experience an inability
by customers and others to pay, on a timely basis or at all, obligations owed
to us. Under these circumstances, the adverse effects, although not
quantifiable at this time, would be material.
 
  We believe that our critical systems will be Year 2000 compliant before
January 1, 2000. Intermedia's Year 2000 Executive Steering Committee convened
in first quarter 1999 and is scheduled to meet regularly throughout the year.
This committee includes members of Intermedia's management and our President,
Nancy G. Faigen. The committee is working to oversee and allocate additional
resources, if required, for the final plans for Year 2000 readiness. Having
identified our mission-critical systems and those of our key suppliers, and the
associated risks of failure to ensure that those systems are Year 2000 ready,
we are in the process of devising contingency plans which will be implemented
in the event any such systems are not Year 2000 compliant in a timely manner.
Business continuity plans are under development by us and will be ready for
implementation by the fourth quarter of 1999.

Industry Background
 
Introduction
 
  Use of the Internet, including intranets and extranets, has grown rapidly in
recent years. This growth has been driven by a number of factors, including the
large and growing installed base of personal computers, improvements in network
architectures, increasing numbers of network-enabled applications, the
emergence of compelling content and commerce-enabling technologies, and easier,
faster and cheaper Internet access. As a result of this growing use, the
Internet has become an important new global communications and commerce medium.
The Internet represents an opportunity for enterprises to interact in new and
different ways with a large number of customers, employees, suppliers and
partners. Enterprises are responding to this opportunity by rapidly increasing
their investment in Internet sites and services.
 
 
                                       34

  Over the last several years, enterprises that focus solely on distributing
products and services over the Internet have emerged and, more recently,
mainstream businesses have begun to implement Web sites to complement
traditional business models and applications. Among the various factors which
continue to attract these businesses to the Internet is the transformation of
Web sites from being primarily text-based and informational to becoming
interactive, multimedia-enabled and transaction oriented. New technologies and
development tools have also led to the Web-enabling of traditional business
functions and applications such as customer service, procurement, human
resource management and sales force automation. Internet operations and
applications are mission-critical for virtually all Web-centric companies and
are becoming increasingly mission-critical for many mainstream enterprises. At
the same time, these operations and applications are becoming more complex and
challenging to operate. Ensuring the quality, reliability, and availability of
these Internet operations typically requires substantial investments in
developing Internet expertise and infrastructures. However, such a continuing
significant investment of resources is often an inefficient use of an
enterprise's limited resources. As a result, businesses are increasingly
seeking collaborative outsourcing arrangements that can increase performance,
provide continuous operation of their Internet solutions, and reduce Internet
operating expenses.
 
  According to Forrester Research, approximately half of the Fortune 1000 firms
they surveyed have outsourced the management of their Web sites. Forrester
reports that companies outsource Web site management primarily for the
following reasons:
 
  .  scarcity of technical skills;
 
  .  performance;
 
  .  speed of implementation; and
 
  .  security.
 
  We believe additional benefits of outsourcing the management of a complex Web
site include lower total costs, higher service level guarantees and reduced
risk of technology obsolescence.
 
Emergence of Web Hosting Service Providers
 
  In order to establish a high quality, reliable Web site or to run a Web-based
application on the Internet, businesses must, among other things, procure and
integrate sophisticated hardware and software, develop application specific
technical skills, and have access to a secure, fault tolerant physical location
and redundant Internet connectivity. While it is possible for a business to
provide all of these elements in-house, many companies elect to outsource all
or a portion of their Web-site operations to companies offering Web hosting
services. Web hosting companies, in general, provide various infrastructure-
related services, including secure, monitored data centers, uninterrupted power
supply and high-speed network connectivity. We categorize the market for
outsourced Web hosting services into the following:
 
  .  Shared Hosting: customers share server hardware and bandwidth with other
     customers. Shared hosting provides a price competitive entry point for
     individuals and businesses desiring a simple Web site.
 
  .  Collocation Hosting: customers own their hardware, software and network
     equipment which is housed at the Web site hosting company's facilities.
     The customers retain responsibility for the installation, management,
     scalability and security of their Web sites. While collocation requires
     the customer to assume the majority of the responsibilities for the
     operation of its Web site, collocation has been and remains an
     attractive option for Web-centric companies with advanced in-house
     Internet expertise.
 
  .  Dedicated Hosting: customers are provided a complete Web site hosting
     solution. Unlike collocation, the service provider supplies the
     hardware, software, network equipment and support necessary to run the
     Web site. As Web sites have become more complex, even large and
     technically astute businesses have found Internet technologies and
     solutions a challenge to manage. For such
 
                                       35
<PAGE>
 
     companies, including many Fortune 2000 companies, dedicated Web site
     hosting has become a preferred alternative.
 
  .  Application Hosting: customers are provided the services of dedicated
     Web site hosting along with the management of Web-enabled business
     applications supporting such common business processes as customer
     service, procurement, human resource management and sales force
     automation. The service provider implements and configures such business
     applications to meet the specific needs of its customers. For large and
     small businesses alike, business process hosting offers numerous
     benefits, including faster time-to-market, access to advanced
     application skills and significantly lower costs of operation.
 
  A variety of companies, such as ISPs and large systems integrators, offer
products and services that attempt to address enterprises' Internet outsourcing
needs. However, we believe the solutions offered by these companies fail to
address certain elements required to ensure that customers' mission-critical
Internet operations are reliable, scalable and responsive. ISPs have
traditionally focused on providing Internet access and many have not developed
the technical expertise and physical resources to support mission-critical Web
sites. In addition, many large systems integrators focus primarily on large
enterprises and traditional information technologies. These firms often lack
the network and Internet expertise required to provide mission-critical
solutions. As a result, we believe a significant opportunity exists for a
highly-focused company to provide a combination of complex Web site hosting,
outsourced applications management and professional consulting services that
enable businesses to implement reliable, high performance and cost effective
mission-critical Internet solutions.
 
The Digex Solution
 
  We focus primarily on providing dedicated Web site and application hosting
services. Our core competency is developing and managing mission-critical Web
solutions for Fortune 2000 companies and Web-centric businesses. We believe we
are uniquely positioned to assist such businesses in optimizing the potential
of the Internet and their Internet-related applications by providing our
customers with the following key advantages:
 
  A Comprehensive Suite of Web Site and Application Hosting Services. We
provide a suite of services that enable companies to conduct business on the
Internet. Using a large, multi-specialized technical staff of certified
engineers, and through the security and reliability of our state-of-the-art
data centers, we provide the services and expertise to ensure secure, scalable,
high-performance operation of mission-critical Web sites 24 hours a day. These
services include:
 
  .  Web site management services such as operating and supporting Windows NT
     and UNIX-based dedicated servers, providing server collocation, and
     private network connectivity;
 
  .  integrated business solutions, which involve the hosting of leading Web-
     enabled business software applications such as electronic commerce,
     sales force automation and customer care;
 
  .  enterprise services such as firewall management, stress testing and
     customized Web site activity reporting; and
 
  .  consulting services including capacity planning, disaster recovery
     planning, migration planning and database optimization.
 
  As part of our services, we provide the installation and maintenance of
industry-leading hardware and software, core technical expertise, high-volume
backup and recovery systems and 24 hours a day monitoring by our Server
Operations Center ("SOC").
 
  High-Performance Internet and Private Network Connectivity. We provide high
performance network connectivity services for our customers' Web sites as well
as direct private networking options for secure "back-end" network connections
to private corporate networks and information systems. Through our network
 
                                       36
<PAGE>
 
services agreement with Intermedia, we offer superior Internet connectivity
that provides the following direct benefits to customers:
 
  .  connectivity to a diversely, redundant high-speed national network via
     Intermedia, a tier-one ISP;
 
  .  use of all of Intermedia's public and private peering relationships
     permitting direct exchange of traffic with a significantly large number
     of carriers and ISPs;
 
  .  use of all of Intermedia's regional direct connections to major ISPs,
     dial-up carriers, and content service providers; and
 
  .  service level agreements guaranteeing high availability and performance.
 
Digex also intends to provide diversified connectivity options to other major
backbones in addition to Intermedia, offering customers an additional service
enhancement. We also intend to establish and maintain our own public and
private peering arrangements.
 
  Responsive Customer Care and Technical Support. We strive to provide superior
customer service. This includes 24-hour a day direct access to a large staff of
customer care and technical support personnel and a variety of proactive
monitoring services from our state-of-the-art SOC. We believe this level of
customer support significantly differentiates Digex in the marketplace.
 
  At our SOC, we monitor and report on the health of servers, networks, and
security devices managed by Digex. The SOC uses a variety of technologies and
tools to monitor specific network devices, such as routers, switches and load
balancing equipment. The SOC oversees a large number of server resources, such
as CPU, system processes, log files, TCP ports, disk space and others, and
security devices, such as firewalls.
 
  Secure, Fault-Tolerant Data Centers. Our data centers have been engineered to
meet the highest expectations of our most demanding customers across our target
markets, including the particularly stringent requirements of the financial
industry.
 
  Our data centers contain multiple, free-standing computer rooms to provide
containment and isolation. Separate mechanical rooms adjacent to each computer
room house cooling and mechanical equipment, eliminating the possible
introduction of liquid into the computer room from equipment leakage. We use
redundant uninterruptable power supply systems and redundant generators to
ensure that the power system is capable of maintaining power to the data center
in the event of any component failure. State-of-the-art physical security has
been implemented through tightly controlled security zones requiring both card
and biometric identification. Over 100 surveillance cameras record all movement
through the data centers and security guards provide real-time visibility.
Cooling and environmental controls for each data center are designed to monitor
and ensure proper temperature and humidity levels. Finally, all
telecommunications connections enter the data centers through multiple points
from diverse service arrangements to ensure continued operation of service
without degradation in the unlikely event of a cable cut or local carrier
network outage.
 
  Predictable Monthly Fees. We provide our services for predictable monthly
fees, enabling our customers to accurately budget costs for Web site hosting
services. These fees are typically contracted as part of one, two or three-year
agreements. These agreements provide service level guarantees and permit
technology upgrades at any time during the life of a contract.
 
Digex Strategy
 
  Our objective is to maintain our leadership position in the industry and
continue to shape and lead the global market for hosting complex Web sites. We
intend to accomplish this by delivering secure, scalable, high-performance Web
site hosting solutions. Our business strategy focuses on the following:
 
  Expand Our Premier Web Hosting Capabilities. We are currently expanding the
capacity of our east and west coast data centers. We intend to continue to add
data center capacity over the next five years as justified
 
                                       37
<PAGE>
 
by customer demand. We believe our ability to readily grow and scale our
operations while simultaneously maintaining the highest service levels will
allow us to continue to attain higher revenues, lower marginal unit costs and
higher operating margins. The following are among the key initiatives we have
instituted to maintain the quality and scalability of our operations:
 
  .  Our Distributed Internet Server Array ("DISA") architecture is
     specifically designed to facilitate Web site operating scalability. DISA
     unifies interrelated layers of hardware and software around industry
     standard solutions. Our customers are strongly encouraged to adopt the
     DISA architecture in implementing their Web initiatives. The consistency
     and reliability afforded by our DISA architecture facilitates rapid and
     cost-efficient implementation of our customers' Web hosting initiatives.
     Other Web hosting companies typically have opted not to standardize
     their operating architectures. The resulting multiple architectures
     significantly complicate and limit the flexibility of their operations.
 
  .  We believe our technical staff is among the most highly skilled and
     trained in the Web hosting industry. We believe our technical staff
     affords us a unique competitive advantage and has been instrumental in
     attracting many of our Fortune 2000 customers. In addition, we believe
     the depth and scope of our staff's technical skill base is essential to
     our ability to maintain our high quality service levels. To attract and
     retain these individuals, we offer competitive financial incentives, in-
     house and external training programs, and the opportunity to work with
     cutting-edge technology.
 
  .  The Digex Central Nervous System (DCNS) is our end-to-end integrated
     customer relationship management system. Currently, DCNS provides
     support for key customer care functions like sales management, contract
     management, order entry, product fulfillment, problem management, and
     billing. It serves as a repository for information about the customer
     and a customer's Web site. Future enhancements include Web-enabling
     DCNS. This will allow customers to access and view the status of their
     account on-line. We believe this functionality will increase customer
     satisfaction while reducing customer service costs.
 
  Address Industry-Specific Customer Needs. Our marketing and operating
strategy is designed to exploit our expertise in addressing the unique,
industry-specific needs of our targeted customer base. This targeted customer
base is comprised of companies and agencies in the following industries:
financial services and insurance, media and entertainment, manufacturing,
travel and hospitality, retail and distribution, technology and communications,
healthcare, and government. We have chosen to focus on these specific
industries because we believe they have the highest propensity to outsource
complex, mission-critical Web sites. We believe this strategy provides a number
of benefits including:
 
  .  the ability to realize cost efficiencies by developing industry-specific
     Web solutions that form the basis for serving other customers in the
     same or similar industries;
 
  .  the ability to develop industry expertise which will enable us to
     proactively address the needs of our customers, thereby differentiating
     Digex from the competition; and
 
  .  development of a referenceable customer base that validates our
     industry-specific Web solutions and expertise.
 
  In conjunction with this strategy, we have designated teams consisting of
individuals from our sales, technical and customer support divisions to focus
exclusively on those specific industries which comprise our target market.
 
  Develop Next Generation Service Offerings.  As the underlying technology and
functionality of Web-based products evolve, we believe customers will
continuously demand new service offerings. We believe the depth of our Web site
management skills positions Digex to be a leading provider of next generation
Web-based service offerings. The following are among the new service
initiatives we are currently pursuing:
 
  .  Web-Enabled Business Applications. We believe Web hosting will become a
     vehicle and platform for operating and supporting leading packaged
     software applications that can be used for such common business
     processes as e-commerce, sales force automation, customer support and
     human
 
                                       38
<PAGE>
 
     resource management. We intend to continue partnering with various
     software developers, systems integrators and information technology
     firms that own and develop these business applications by providing the
     Web hosting platform to deliver their applications over the Web. To
     date, we focus on providing applications which address the following
     areas:
 
    .  electronic commerce solutions, such as on-line storefronts, including
       electronic catalogs and shopping carts;
 
    .  business intelligence solutions, such as analytic applications to
       mine corporate data warehouses;
 
    .  relationship management solutions, such as customer acquisition,
       self-service, and self-sales applications;
 
    .  human resources solutions, such as recruiting, training and on-line
       benefits applications;
 
    .  finance and accounting solutions, such as billing and time-tracking
       applications; and
 
    .  supply chain management solutions, such as procurement, trading and
       other intercompany applications.
 
  .  Value-added, Recurring Services. We have developed various value-added
     services, which we believe significantly enhance the availability and
     effectiveness of our customers' Web sites. Examples of these services
     are testing, security, database, reporting and intranet service
     offerings. We intend to continue developing services that improve the
     effectiveness of Web sites and optimize their performance.
 
  .  Proactive Customer Service Management. We believe our hardware and
     software monitoring capabilities uniquely position us to anticipate the
     Web site hosting needs of our existing customers. We are developing new
     tools which will both facilitate the identification of problems with a
     customer's existing Web site hosting platform and alert client managers
     to the Digex services that can be used to address these issues and
     optimize Web site performance.
 
  Expand Capabilities Through Selective Strategic Partnering and
Acquisitions. We currently have partnership alliances with over 120 Web design
and development companies and interactive media agencies. These businesses
typically partner with Digex because our high quality services support and
augment, rather than compete with, their own product and service offerings.
Together with our business partners, we can provide our customers with end-to-
end Web site solutions. In 1998, we created the Digex e-Link Partner
Program(TM), which continues to attract leading interactive media and Web
development companies such as Proxicom, Sapient, Studio Archetype and
Agency.com. In addition, during the second quarter of 1999, we are planning to
launch the Digex app-Link Partner Program(TM) in order to expand our
partnership alliances to include systems integrators, value-added resellers
and consultants. Our partnership programs provide a valuable, cost-effective
channel for our services as well as a highly productive customer referral
source.
 
  In addition, we may seek to opportunistically acquire companies which we
believe will enable us to cost-effectively augment our existing products and
services, technology, infrastructure, skill set, geographic presence or
customer base.
 
Digex Services
 
  We offer a full range of complementary value-added services designed to
handle the rapidly evolving requirements of complex Web sites. Our services
include the following:
 
  .  Web site management services;
 
  .  integrated business solutions;
 
  .  enterprise services; and
 
  .  consulting services.

  .  dedicated security options;
 
  .  standard rack equipment; and
 
  .  special rates on Digex services.
 
  Intelligent Networking. We offer a variety of intelligent networking services
to customers with multiple servers, including load balancing and geographical
distribution of network traffic. We expect demand for this product to increase
as more customers move to multiple server solutions.
 
  Private Networking. Our private networking services are primarily used to
securely connect a customer's Web site at Digex to their private corporate
network or information system.
 
  Integrated Business Solutions (IBS)
 
  Our Integrated Business Solutions provide customers with Web site hosting
services designed specifically to operate and support leading packaged software
applications. We partner closely with the business applications vendors to
build valuable skills around their applications with an emphasis on the
operation of the application on the Internet.
 
 
                                       40
<PAGE>
 
  Our IBS services specifically target six distinct functional solution areas:
electronic commerce, business intelligence, relationship management, human
resources, finance and accounting solutions and supply chain management. We
provide application rental, application hosting services and compelling service
level guarantees to our customers. The key benefits of these solutions include:
 
  .  installation and maintenance of pre-configured and pre-tested bundles of
     the solution on a hardware configuration that handles predicted user
     capacity;
 
  .  application software rental and upgrades;
 
  .  dedicated support personnel;
 
  .  advanced data recovery and storage options for the specific application
     and database; and
 
  .  special rates on other Digex products and services.
 
  Our IBS services are detailed as follows:
 
  Electronic Commerce Solutions. Our electronic commerce solutions enable
businesses to directly sell products and services over the Internet to create
an on-line storefront, including electronic catalogs and shopping carts. These
solutions include options for order processing, fulfillment, invoicing, and
payment. Digex's private networking products permit businesses to connect their
commerce Web sites to various payment processing centers and private corporate
information systems ensuring customers secure routing of payment information
and transaction processing.
 
  The Pandesic e-Business Solution(TM) is our first electronic commerce
solution offering. Pandesic is a joint venture between SAP and Intel, offering
end-to-end commerce functionality for businesses. Today, Digex manages over 45
customers using the Pandesic solution, representing over 100 servers.
 
  Business Intelligence Solutions. Our business intelligence solutions will
provide customers fast and easy access to corporate information using analytic
applications to mine corporate data warehouses. By leveraging the Internet and
Digex's business intelligence solutions, businesses empower executives,
employees, shareholders, partners, and others with access to up-to-date
information. We believe these applications facilitate sophisticated analysis
and real-time monitoring of important indicators to assist companies in their
decision making processes.
 
  Relationship Management Solutions. Our relationship management solutions will
provide customers with the ability to extend critical business information to
sales personnel and customers. These solutions include customer acquisition,
self-service and self-sales applications.
 
  Human Resources Solutions. Our human resources solutions will provide
customers with the ability to take advantage of the Internet to extend human
resource functionality to employees anywhere, anytime. Companies will be able
to improve their ability to manage open positions, performing activities such
as recruiting and training and to allow employees to access on-line and modify
benefits and other personal information.
 
  Finance and Accounting Solutions. Our finance and accounting solutions will
provide customers with support for accounting, billing, compensation, time
tracking, and other financial management functions. For example, Digex can
manage a company's time and expense reporting application to provide global
access for employees to enter time sheets and expense reports.
 
  Supply Chain Management Solutions. Our supply chain management solutions will
provide customers with application solutions that help businesses improve the
effectiveness and reliability of a company's supply chain system. Using the
Internet as the vehicle, these solutions can extend a company's supply chain
management system to otherwise cost-prohibitive partners, improving performance
and lowering costs.

  Enterprise Services
 
  Our enterprise services help companies deploy and maintain effective Web
sites. We believe these value-added, repeatable services will become
increasingly important to our customers as they look to ensure a higher level
of Web site availability, security and reporting. Our enterprise services
include the following:
 
  Testing Services. Our testing services aim to identify problems that could
degrade the expected performance and availability of a customer's Web site. For
example, our stress testing services simulate users accessing a Web site to
provide information for isolating problems, optimizing performance and
accelerating the deployment of Web sites.
 
  Reporting Services. Our reporting services are designed to provide timely,
reliable information about user activity on a customer's Web site. Businesses
can use these reports to assess the effectiveness of their Web sites and to
increase their knowledge of the preferences, habits and demographic
characteristics of their Web site visitors.
 
  Security Services. Our security services are designed to ensure the security
of a customer's Web site. These services include firewalls, encryption and
authentication devices.
 
  Database Services. Our database services provide the installation,
configuration, maintenance and support of leading databases.
 
Consulting Services
 
  Our consulting services provide customized assistance to customers with
unique architecture, deployment or maintenance requirements. These services
include high-availability design, performance tuning, site architecture
assessment, migration planning, capacity planning, disaster recovery planning
and database optimization. Our consulting services typically assist customers
with limited resources or who lack Internet and technical expertise. Our
consulting engagements typically range from a few hours to a few weeks
depending on the complexity and volume of the services needed. We believe our
consulting services will play an increasingly important role in supporting the
implementation and maintenance of complex Web sites as customers continue to
rapidly adopt emerging technologies.
 
Customers
 
  We have a large and diverse customer base ranging from Fortune 50 companies
to small and medium size businesses that rely heavily on the Internet. Our
customers are primarily located within the United States. As of April 1, 1999,
we were serving over 550 customers, covering most major industries. Our
customer contracts typically range in duration from one to three years. The
majority of our customers operate in industries which fall within our key
targeted industry segments and include the following:

Sales, Marketing and Service Delivery
 
  Our sales objective is to achieve broad market penetration by focusing on
market segments which, we believe, have both a high propensity to outsource and
to deploy complex, mission-critical Web sites. We sell our services directly
through a highly-skilled professional sales force and receive referrals through
an extensive network of business partners.
 
  Direct Sales. As of April 1, 1999, our direct sales force consisted of over
60 experienced, quota-bearing sales representatives. We have organized the
sales force into three units: major accounts, mid-market/Web-centric, and
alternate channel. The major accounts unit focuses on Fortune 2000 companies
and is aligned by industry. The mid-market/Web-centric unit addresses the large
and growing number of referrals coming from our regionally based business
partners, and is organized into three geographic regions: eastern, central and
western United States. Our alternate channel sales group works closely with our
business alliance solutions partners, such as Pandesic. Supporting each of
these units is a site engineering team that provides pre-sales technical
support, including requirements gathering, configuration support, site
architecture, and project management.
 
  Strategic Partners--The Digex e-Link Partner ProgramTM. In 1998, we created
the Digex e-Link Partner Program(TM), which, we believe, has attracted some of
the leading interactive media and Web site development companies to partner
with Digex. To date, our business partners include such companies as Proxicom,
Agency.com, Xerox Connect and T3 Media. We currently have over 120 business
partnership alliances that are a significant source of sales leads and
opportunities. These business partners include Web site developers, Web site
designers, interactive and new media agencies, and systems integrators. We
collaborate, instead of compete, with our partners and complement each other's
skills in an effort to bring the best overall solution to our customers.
Typically, in these collaborative relationships, we focus on Web site hosting,
while our strategic partners concentrate on Web site design, development and
systems integration.
 
   The success of this program has encouraged us to introduce the Digex app-
Link Partner Program(TM). The Digex app-Link Partner Program(TM) will target
consultants and systems integrators, value-added hardware resellers and
application solution providers. Our partnership programs provide incentives to
refer business to us, and we often work together with our partners directly
with the client. Our strategy is to continue leveraging our partners as a
referral channel and a source for identifying market trends and emerging
customer requirements.
 
  Marketing. We intend to continue our transformation into a highly focused,
market driven company. Our marketing organization is responsible for building
Digex's brand awareness, identifying key target markets and developing
innovative services to meet the evolving demands of the marketplace. Another
objective of our marketing effort is to stimulate the demand for Digex services
through a broad range of marketing communications and public relations
activities. Our primary communication vehicles include advertising, trade
shows, direct response programs, event sponsorship and the Digex Web sites.
 
Data Center Infrastructure
 
  We presently operate two highly secure, fault-tolerant data centers
specifically designed for the 24-hour a day hosting of Web sites and Web-based
applications. Our east coast data center is strategically located near major
network access points (NAPs) in the Washington, D.C. metropolitan area. Our
west coast data center is situated near the western NAPs and the headquarters
of many of our strategic technology providers. We are expanding our total data
center capacity to over 225,000 square feet in 1999, and expect to add
additional data center capacity over the next five years as appropriate to meet
anticipated customer and market demand.
 
  Our data centers combine the predictability and control of traditional
mainframe-based data centers with the network access and capacity required for
today's Internet-based computing. Our data centers are designed to provide
consistently high service levels while permitting customers to rapidly deploy
new and strategic applications without substantially increasing cost or
incurring risk.

<PAGE>
 
  The physical infrastructure and security controls of our data centers have
been designed to support rigorous requirements for secure data storage and
processing. Specifically, our data centers offer the following major physical
benefits to our customers:
 
  .state-of-the-art physical security;
 
  .multi-redundant mechanics, utilities and environmental controls;
 
  .high-performance multi-network points of presence (WebPOPs); and
 
  .fully-integrated customer work-areas.
 
  State-of-the-art physical security. Our data centers include multiple
separate computer rooms offering customers a high degree of containment and
isolation from accidents or disasters occurring within or outside of each data
center. Physical security has been implemented through tightly controlled
security zones requiring both access card and biometric identification. Each
data center has five security zones that require separate access levels to gain
entry. Our highest security zones include computer rooms physically constructed
as a building-within-a-building, with fire suppression and other controls
separate from the remainder of the data center. Fencing above the ceiling and
below the raised floor isolate each security zone. Over 100 surveillance
cameras record all movement through the data centers and security guards
provide real-time visibility. Our cooling towers are surrounded by security
fences and monitored by cameras. Our dual 20,000 gallon diesel fuel tanks are
safely buried underground.
 
  Multi-redundant mechanics, utilities and environmental controls. Within each
data center, separate mechanical rooms exist adjacent to each computer room.
These mechanical rooms house all cooling and mechanical equipment, eliminating
the possible introduction of liquid into the computer rooms from equipment
leakage. We use redundant uninterruptable power supply systems and redundant
generators, to ensure the power system is capable of maintaining power to the
data center in the event of any component failure. Cooling and environmental
controls for each data center are designed to monitor and ensure proper
temperature and humidity.
 
  High-performance WebPOPs. Our data centers include physically separated
WebPOPs, which are network points of presence within our data centers. These
WebPOPs provide high-performance, reliable networking connectivity to multiple
national Internet backbone carriers for our customers. Telecommunications
circuits enter the data centers through multiple points from diverse service
providers. Multiple points of presence ensure continued operation of service
without degradation in the unlikely event of a cable cut or local carrier
network outage.
 
  Fully-integrated customer work areas. Our data centers include separate,
private customer work areas. These work areas are isolated from the security
zones that house our servers permitting customers to work on on-site as
necessary. These work areas provide computing and personal resources, such as
customer breakrooms and wash areas.
 
Competition
 
  The market served by Digex is highly competitive. There are few substantial
barriers to entry, and we expect to face additional competition from existing
competitors and new market entrants in the future. The principal competitive
factors in this market include Internet system engineering expertise, customer
care, network capability and quality of service.
 
  Our current and potential competitors in the market include:
 
  .  Web hosting service providers;
 
  .  local, regional, national and international ISPs;
 
  .  local, regional, national and international telecommunications
     companies; and
 
  .  large information technology outsourcing firms.
 
 
                                       44
<PAGE>
 
  Our competitors may operate in one or more of these areas and include
companies such as AboveNet Communications, AT&T, Cable & Wireless, Concentric
Network, EDS, Exodus Communications, Frontier/GlobalCenter, Globix, GTE, Intel,
Level 3 Communications, MCI WorldCom, PSINet, IBM, Qwest Communications
International, and USinternetworking.
 
  We believe our experience and reputation for delivering high quality, complex
Web site hosting services differentiate us from our key competitors. We focus
on our core competency of Web site and application hosting as opposed to
offering hosting as a complement to a wide range of communication services. We
believe we have defined and offer the industry's most complete set of functions
required to configure, engineer, implement and maintain complex, transactional
Web sites. We believe our DISA architecture, data centers, and technical team
distinguish us from our competition and enable us to provide among the highest
quality end-to-end complex Web site hosting solutions.
 
Intellectual Property Rights
 
  We rely on a combination of copyright, trademark, service mark and trade
secret laws and contractual restrictions to establish and protect certain
proprietary rights in our data, applications and services. We have no patented
technology that would bar competitors from our market. We also rely on certain
technologies we license from third parties, such as Microsoft, Netscape and
Micromuse. There can be no assurance these third-party technology licenses will
continue to be available to us on commercially reasonable terms. The loss of
such technology could require us to obtain substitute technology of lower
quality or performance standards or at greater cost, which could harm our
business. However, other than our trademarks and service marks, we do not
believe that the loss of any particular one of our intellectual property rights
would harm our business.
 
Government Regulation
 
  We are not currently subject to direct federal, state or local government
regulation, other than regulations applicable to businesses generally. There is
currently only a small body of laws and regulations directly applicable to
access to or commerce on the Internet.
 
  Congress recently enacted the "Digital Millennium Copyright Act," which
became effective in October 1998. The Digital Millennium Copyright Act includes
a limitation on liability of on-line service providers for copyright
infringement for transmitting, routing, or providing connections, transient
storage, caching or storage at the direction of a user. This limitation on
liability applies if the service provider had no actual knowledge or awareness
that the transmitted or stored material was infringing and if certain other
conditions are met. Since this law is new, we are unsure of how it will be
applied to limit any liability we may face in the future for any possible
copyright infringement or copyright-related issues. This new law also requires
ISPs to follow certain "notice and take-down" procedures in order to be able to
take advantage of the limitation on liability. We have not yet implemented such
procedures nor evaluated the cost of complying with them. However, our
customers are subject to an acceptable use policy which prohibits them from
posting, transmitting or storing material on or through any of our services
which, in our sole judgment is (1) in violation of any local, state, federal or
foreign law or regulation, (2) threatening, obscene, indecent or defamatory or
that otherwise could adversely affect any individual, group or entity or (3) in
violation of the intellectual property rights or other rights of any person.
Although this policy is designed to promote the security, reliability and
privacy of our systems and network, there is no assurance that our policy will
accomplish this goal or shield us from liability under the Digital Millennium
Copyright Act.
 
  Despite enactment of the Digital Millenium Copyright Act, the law relating to
the liability of on-line services companies and Internet access providers for
information carried on or disseminated through their networks remains largely
unsettled. It is possible claims could be made against on-line services
companies and Internet access providers under both United States and foreign
law for defamation, obscenity, negligence, copyright or trademark infringement,
or other theories based on the nature and content of the materials
 
                                       45
<PAGE>
 
disseminated through their networks. Several private lawsuits seeking to impose
such liability upon on-line services companies and Internet access providers
are currently pending.
 
  Although sections of the Communications Decency Act of 1996 that proposed to
impose criminal penalties on anyone distributing indecent material to minors
over the Internet were held to be unconstitutional by the U.S. Supreme Court,
similar laws may be proposed, adopted and upheld. The nature of future
legislation and the manner in which it may be interpreted and enforced cannot
be fully determined and, therefore, legislation similar to the Communications
Decency Act could subject us and/or our customers to potential liability, which
in turn could have a material adverse effect on our business. The adoption of
any of these types of laws or regulations might decrease the growth of the
Internet, which in turn could decrease the demand for our services or increase
our cost of doing business or in some other manner have a material adverse
effect on our business.
 
  Due to the increasing popularity and use of the Internet, it is likely a
number of additional laws and regulations may be adopted at the federal, state
and local levels with respect to the Internet, covering issues such as user
privacy, freedom of expression, pricing, characteristics and quality of
products and services, taxation, advertising, intellectual property rights,
information security and the convergence of traditional telecommunications
services with Internet communications. The adoption of any such laws or
regulations might decrease the growth of the Internet, which in turn could
decrease the demand for our services or increase the cost of doing business or
in some other manner have a material adverse effect on our business, results of
operations or financial condition. In addition, applicability to the Internet
of existing laws governing issues such as property ownership, copyrights and
other intellectual property issues, taxation, libel, obscenity and personal
privacy is uncertain. The vast majority of such laws were adopted prior to the
advent of the Internet and related technologies and, as a result, do not
contemplate or address the unique issues of the Internet and related
technologies.
 
Employees
 
  As of April 1, 1999, we employed approximately 436 full-time employees. None
of our employees are covered by a collective bargaining agreement. We believe
that our employee relations are good.
 
Properties
 
  We currently share leased space with Intermedia totaling approximately 80,000
square feet in two buildings in Beltsville, Maryland. These facilities house
our east coast data center, our executive and administrative offices, and our
regional sales office. At the end of June 1999, we expect to relocate to two
different leased buildings in Beltsville, Maryland occupying a total of
approximately 122,000 square feet. We also lease a total of approximately
76,000 square feet in two other buildings--one in Cupertino, California, and
one in San Jose, California. These house our west coast data facilities and
regional sales office. We believe that our properties are adequate and suitable
for their intended purposes.
 
Legal Proceedings
 
  We do not believe that there are any pending or threatened legal proceedings
that, if adversely determined, would have a material adverse effect on us.

Indemnifications of Directors and Executive Officers and Limitation of
Liability
 
  Our certificate of incorporation includes a provision that eliminates the
personal liability of our directors for monetary damages for breach of
fiduciary duty as a director, except for liability:
 
  .for any breach of the director's duty of loyalty to us or our
  stockholders;
 
 
                                       51
<PAGE>
 
  .  for acts or omissions not in good faith or that involve intentional
     misconduct or a knowing violation of law;
 
  .  under section 174 of the Delaware General Corporation Law regarding
     unlawful dividends and stock purchases; or
 
  .  for any transaction from which the director derived an improper personal
     benefit.
 
These provisions are permitted under Delaware law.
 
  Our bylaws provide that:
 
  .  we must indemnify our directors, officers, employees and agents to the
     fullest extent permitted by Delaware law, subject to certain very
     limited exceptions; and
 
  .  we must advance expenses, as incurred, to our directors and executive
     officers in connection with a legal proceeding to the fullest extent
     permitted by Delaware Law, subject to certain very limited exceptions.
 
  We intend to obtain directors' and officers' insurance providing
indemnification for our directors, officers and certain employees for certain
liabilities.
 
  The limitation of liability and indemnification provisions in our certificate
of incorporation and bylaws may discourage stockholders from bringing a lawsuit
against directors for breach of their fiduciary duty. They may also have the
effect of reducing the likelihood or derivative litigation against directors
and officers, even though such an action, if successful, might otherwise
benefit us and our stockholders. Furthermore, a stockholder's investment may be
adversely affected to the extent we pay the costs of settlement and damage
awards against directors and officers pursuant to these indemnification
provisions.
 
  There is no pending litigation or proceeding involving any of our directors,
officers or employees regarding which indemnification is sought, nor are we
aware of any threatened litigation that may result in claims for
indemnification.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling Digex pursuant
to the foregoing provisions, we have been informed that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  Prior to the closing of this offering, we will enter into the following
agreements with Intermedia: General and Administrative Services Agreement,
Master Network Services Agreement, Public Internet Access Services Agreement,
and Customer Network and Application Services Agreement. These agreements are
described below. The General and Administrative Services Agreement is included
as an exhibit to the registration statement of which this prospectus forms a
part.
 
General and Administrative Services Agreement
 
  Under the General and Administrative Services Agreement, Intermedia will
provide us with a variety of general and administrative services, including:
 
  . finance, accounting and administration services, such as cash management,
    corporate banking, risk management, liability insurance, debt management,
    filing of state and federal tax returns, assistance in evaluating and
    structuring potential acquisitions, coordination of required public
    filings, fixed asset reporting, accounts payable, accounts receivable and
    collection, general ledger, and purchasing management;
 
  . human resources services, such as employee and labor relations, employee
    and management training;
 
  . legal services in the areas of labor, employment and litigation
    management;
 
  . Year 2000 compliance services; and
 
  . network engineering services, as we may request from time to time.
 
  The General and Administrative Services Agreement will provide for a five-
year initial term. Thereafter, the term will be automatically renewed for a
two-year term, unless at least six months prior to the termination of the
initial term either we or Intermedia notifies the other that it does not wish
to renew the term. In addition, we may terminate any of the services provided
to us on 90-day prior notice at any time after the 60th day after the
completion of this offering, except that we may not:
 
  . terminate, other than for cause or after a change of control of Digex,
    the tax and treasury management services during the initial term; or
 
  . give notice of termination of any of the finance, accounting,
    administration and Year 2000 compliance services during the period
    between October 1, 1999 and February 28, 2000.
 
Master Network Services Agreement, Public Internet Access Services Agreement,
and Customer Network and Application Services Agreement
 
  We expect that Intermedia directly or through Business Internet will be our
preferred provider of a variety of Internet access, network and related value-
added services in the following two categories:
 
  . public internet access services for the transit of data from our data
    centers to the Internet, and assisting in the design, implementation and
    management of Internet points of presence for the routing of our data
    traffic to Intermedia's and other network service providers' networks
    ("Internet Access Services"); and
 
  . customer products and services for resale by us to our customers under
    the Digex and/or Intermedia brand ("Customer Services").
 
  Prior to the closing of this offering, we will enter into a Master Network
Services Agreement (the "Master Agreement"), Public Internet Access Services
Agreement (the "Access Agreement"), and Customer Network and Application
Services Agreement with Intermedia (the "Customer Services Agreement") for the
provision of these services to us by Intermedia.
 
  The Master Agreement contains the general terms and conditions under which
Intermedia will provide to us the Internet Access Services and the Customer
Services. The Master Agreement has an initial term of two
 
                                       53
<PAGE>
 
years, which is automatically renewable for successive one-year periods. Either
we or Intermedia may elect not to renew the term by giving the other party
notice at least six months before the scheduled expiration of the initial term
or the then current renewal term.
 
  The Access Agreement contains specific provisions that apply to Internet
Access Services. The Customer Services Agreement applies specifically to
Customer Services. The Access Agreement and the Customer Services Agreement,
together, are referred to as the "Services Agreements." Specific service orders
will be issued under each of the Services Agreements to specify the details for
the particular services to be provided.
 
  The Master Agreement provides, among other things, that:
 
  . we will be treated as a most favored customer entitled to rates and fees
    as low as those granted by Intermedia to any other customer purchasing
    substantially similar services, provided that we purchase 70% of our non-
    peered requirements from Intermedia;
 
  . we may request and receive from Intermedia additional services or feature
    enhancements to the services described above;
 
  . we and Intermedia will share with each other customer information and may
    market products and services to each others' customers; and
 
  . during the term of this agreement and for six months after its
    termination, neither party is allowed to compete with the "core" business
    of the other. Our core business is defined to include the dedicated Web
    hosting business as currently conducted by us. Intermedia's core business
    is defined to include the services described in the related Service
    Agreements as conducted by Intermedia.
 
  The Master Agreement limits Intermedia's aggregate liability to us to the
average monthly recurring charges paid by us for the particular service to
which our claim may pertain, and also excludes any consequential or other
special damages. Other than specific service level commitments set out in the
Services Agreements, Intermedia's services under the Master Agreement are
provided on an "as is" and "as available" basis without any express or implied
warranties.
 
  Internet Access Services. Under the Access Agreement, we will be required to
purchase from Intermedia, and Intermedia will provide us through its own
network and its peering arrangements, 70% of our requirements for non-peered
network transit services. The Access Agreement contemplates that we will
provide quarterly forecasts of our network capacity requirements to Intermedia.
If Intermedia does not have the capacity to, or otherwise elects not to,
fulfill any portion of this 70% requirement, we may purchase this portion of
the 70% requirement from other network providers. We may purchase the remaining
non-peered network transit services (up to 30% of our requirements) from other
network service providers, provided that Intermedia may take over these
arrangements and succeed to us as provider of record for this transit if
Intermedia determines that doing so will not endanger its tier-one status as a
network service provider and ISP and otherwise comply with law and industry
standards. We believe that this arrangement will enable us to provide customer
diversity and network balancing, and to meet specific customer and
international requirements. Because of our commitment to obtain at least 70% of
our non-peered network service requirements from Intermedia, we will receive
certain discounts on monthly recurring charges based on the volume of our
traffic.
 
  Intermedia has made certain service level commitments to us for its network
transit services. These commitments cover both network availability and
performance (packet delivery and latency). In addition, we will be one of
Intermedia's major customers and will receive dedicated support under
Intermedia's Major Customer Program.
 
  Under the Access Agreement, Intermedia will also assist us in the design,
implementation and management of Internet points of presence for the routing of
data traffic from each of our data centers to Intermedia's and other network
service providers' networks.
 
 
                                       54
<PAGE>
 
  Customer Services. Customer Services that Intermedia will provide to us, and
which we will be able to market and sell to our customers under the Digex
and/or Intermedia name, include:
 
  . Internet access services offered by Intermedia to its customers;
 
  . wide area network services, such as frame relay and ATM;
 
  . managed connectivity services;
 
  . value-added services, such as worldwide remote dial access to the
    Internet, firewall installation and other security solutions, e-mail
    relay back-up services, messenger mail services, fax over IP services
    that provide Web-to-fax and fax-to-Web capability, and news services
    enabling customers to have access to USENET news groups and to operate
    news servers; and
 
  . private line point-to-point services such as 56k, T1 and DSL.
 
Restructuring Transactions
 
  In conjunction with this offering, Business Internet has contributed to us
the Web hosting business described in this prospectus in exchange for all the
shares of our Class B Common Stock.
 
Relationship with Bear, Stearns & Co. Inc.
 
  Bear, Stearns & Co. Inc. is serving as joint lead underwriting manager of
this offering for Digex. Pierce J. Roberts, Jr., who is currently serving as a
director of Digex, was an employee of Bear Stearns until August 1998.
Immediately prior to his departure from Bear Stearns, Mr. Roberts served as a
Senior Managing Director and head of the Global Telecommunications Group.
 
  Bear Stearns or its affiliates have provided and may in the future provide
investment banking or other financial services to Intermedia, the parent
company of Digex, and its affiliates in the ordinary course of business, for
which it has received and is expected to receive customary fees and expenses.
Bear Stearns has been an initial purchaser for numerous issuances of securities
by Intermedia.

    , 1999, there were outstanding     shares of Class B Common Stock, all of
which were owned by Intermedia through Business Internet, its wholly-owned
subsidiary.
 
  The following summary is qualified by our certificate of incorporation and
bylaws, which are included as exhibits to the registration statement of which
this prospectus forms a part.
 
Common Stock
 
  Shares of Class A Common Stock and Class B Common Stock are substantially
identical in all respects except that: (1) the holders of Class B Common Stock
are entitled to 10 votes per share, and the holders of Class A Common Stock are
entitled to one vote per share on all matters submitted to a vote of
shareholders; and (2) each share of Class B Common Stock is convertible into
one share of Class A Common Stock at the option of the holder and automatically
upon the occurrence of a Conversion Event. A "Conversion Event" is defined as a
direct or indirect transfer of beneficial ownership of Class B Common Stock to
any person or entity that does not control, is not controlled by and is not
under common control with Intermedia.
 
  Subject to preferences that may be applicable to any preferred stock
outstanding at the time, the holders of our outstanding shares of Common Stock
are entitled to receive dividends out of legally available assets at such times
and in such amounts as the board of directors from time to time may determine.
Cumulative voting for the election of directors is not authorized by our
certificate of incorporation, which means that the holders of a majority of the
votes can elect all of the directors then standing for election. The Common
Stock is not entitled to preemptive rights and, except as described in the
preceding paragraph with respect to Class B Common Stock, is not subject to
conversion or redemption. Upon liquidation, dissolution or winding-up, the
assets legally available for distribution to stockholders are distributable
ratably among the holders of the Common Stock after payment of liquidation
preferences, if any, on any outstanding preferred stock and payment of other
claims of creditors. Each outstanding share of Common Stock, and all Common
Stock paid for after this offering, is duly and validly issued, and fully paid
and nonassessable.
 
Preferred Stock
 
  The board of directors is authorized, subject to any limitations prescribed
by Delaware law, to issue preferred stock in one or more series. The board of
directors can fix the rights, preferences and privileges of the shares of each
series and any qualifications, limitations or restrictions thereon.
 
  The board of directors may authorize the issuance of preferred stock with
voting or conversion rights that could adversely affect the voting power or
other rights of the holders of Common Stock. The issuance of preferred stock,
while providing flexibility in connection with possible acquisitions and other
corporate purposes could, among other things, under certain circumstances, have
the effect of delaying, deferring or preventing a change in control of Digex.
We have no current plan to issue any shares of preferred stock.
 
Delaware Anti-Takeover Law
 
  We are subject to the provisions of Section 203 of the Delaware General
Corporation Law concerning corporate takeovers. This section prevents certain
Delaware corporations from engaging, under certain circumstances, in a
"business combination," which includes a merger or sale of more than 10% of the
corporation's assets, with any "interested stockholder," or a stockholder who
owns 15% or more of the corporation's outstanding voting stock, as well as
affiliates and associates of any such persons, for three years following the
date that such stockholder became an "interested stockholder" unless:
 
                                       57
<PAGE>
 
  . the transaction in which such stockholder became an "interested
    stockholder" is approved by the board of directors prior to the date the
    "interested stockholder" attained such status;
 
  . upon consummation of the transaction that resulted in the stockholder's
    becoming an "interested stockholder," the "interested stockholder" owned
    at least 85% of the voting stock of the corporation outstanding at the
    time the transaction commenced, excluding those shares owned by persons
    who are directors and also officers; or
 
  . on or subsequent to such date the "business combination" is approved by
    the board of directors and authorized at an annual or special meeting of
    stockholders by the affirmative vote of at least two-thirds of the
    outstanding voting stock that is not owned by the "interested
    stockholder."
 
  This statute could prohibit or delay mergers or other takeover or change-in-
control attempts with respect to Digex and, accordingly, may discourage
attempts to acquire us.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, we will have outstanding an aggregate of
     shares of our Common Stock, assuming no exercise of the underwriters'
over-allotment option, and      shares of Class B Common Stock. All shares of
Class B Common Stock are convertible into shares of our Class A Common Stock,
on a one-for-one basis, at any time at the option of the holder or upon a
direct or indirect transfer to any person or entity not affiliated with
Intermedia. All of the shares sold in this offering will be freely tradable
without restriction or further registration under the Securities Act, unless
such shares are purchased by "affiliates" as that term is defined in Rule 144
under the Securities Act. The      shares of Class B Common Stock, and the
shares of Class A Common Stock into which they are convertible, held by
Intermedia are "restricted securities" as that term is defined in Rule 144
under the Securities Act. Restricted securities may be sold in the public
market only if registered or if they qualify for an exemption from registration
under Rule 144 or 701 promulgated under the Securities Act, which rules are
summarized below.
 
  As a result of the contractual restrictions described below and the
provisions of Rule 144 and 701, the restricted securities will be available for
sale in the public market on the date which is one year from the date of the
effectiveness of the reorganization, subject to the volume limitations and
other conditions of Rule 144. The shares could be available for resale
immediately upon the expiration of such    -day period in the event of a
favorable interpretation by the Securities and Exchange Commission of certain
provisions of Rule 144.
 
Lock-Up Agreements
 
  All of our officers, directors and stockholders have signed lock-up
agreements under which they agreed not to transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for shares of Common Stock, for a period of 180
days after the date of this prospectus. Transfers or dispositions can be made
sooner with the prior written consent of      or as provided in the
stockholders' agreement.
 
Rule 144
 
  In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
Class A Common Stock for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of:
 
  . 1% of the number of shares of Class A Common Stock then outstanding,
    which will equal approximately      shares immediately after this
    offering; or
 
  . the average weekly trading volume of the Class A Common Stock on the
    Nasdaq National Market during the four calendar weeks preceding the
    filing of a notice on Form 144 with respect to such sale.
 
  Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about us.
 
Rule 144(k)
 
  Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.
 
                                       59
<PAGE>
 
Therefore, unless otherwise restricted, "144(k) shares" may be sold immediately
upon the completion of this offering.
 
Rule 701
 
  In general, under Rule 701 of the Securities Act as currently in effect, any
of our employees, consultants or advisors who purchases shares from us in
connection with a compensatory stock or option plan or other written agreement
is eligible to resell such shares 90 days after the effective date of this
offering in reliance on Rule 144, but without compliance with certain
restrictions, including the holding period, contained in Rule 144.
 
Stock Options
 
   Prior to this offering, we intend to adopt an equity incentive compensation
plan. Immediately after this offering, we intend to file a registration
statement under the Securities Act covering       shares of Class A Common
Stock that will be reserved for issuance under our equity incentive plan and
the directors' stock option plan and the shares reserved for issuance upon
exercise of outstanding non-plan options. Such registration statement is
expected to be filed and become effective as soon as practicable after the
effective date of this offering. Accordingly, shares registered under such
registration statement will, subject to vesting provisions and Rule 144 volume
limitations applicable to our affiliates, be available for sale in the open
market immediately after the 180-day lock-up agreements expire.

</TABLE>
 
  The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares included in this
offering are subject to approval of legal matters by their counsel and to
customary conditions, including the effectiveness of the registration
statement, the continuing correctness of our representations to them, the
receipt of a "comfort letter" from our accountants, the listing of the common
stock on the Nasdaq National Market and no occurrence of an event that would
have a material adverse effect on our business. The underwriters are obligated
to purchase and accept delivery of all the shares, other than those covered by
the over-allotment option described below, if they purchase any of the shares.
 
  We have granted to the underwriters an option, exercisable for     days from
the date of the underwriting agreement, to purchase up to     additional shares
at the public offering price less the underwriting fees. The underwriters may
exercise such option solely to cover over-allotments, if any, made in
connection with this offering. To the extent that the underwriters exercise
such option, each underwriter will become obligated, subject to conditions, to
purchase a number of additional shares approximately proportionate to such
underwriter's initial purchase commitment.
 
  The underwriters propose to initially offer some of the shares directly to
the public at the public offering price set forth on the cover page of this
prospectus and some of the shares to dealers at the public offering price less
a concession not in excess of $    per share. The underwriters may allow, and
such dealers may re-allow, a concession not in excess of $    per share on
sales to other dealers. After the initial offering of the shares to the public,
the representatives of the underwriters may change the public offering price
and such concessions. The underwriters do not intend to confirm sales to any
accounts over which they exercise discretionary authority.
 
  The following table shows the underwriting fees to be paid to the
underwriters by us in connection with this offering. These amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase additional shares of the Class A Common Stock.

  In order to facilitate the offering of the Class A Common Stock, the
underwriters may engage in transactions that stabilize, maintain or otherwise
affect the market price of the Class A Common Stock. Specifically, the
underwriters may over-allot shares of the Class A Common Stock in connection
with this offering, thereby creating a short position in the Class A Common
Stock for their own account. Additionally, to cover such over-allotments or to
stabilize the market price of the Class A Common Stock, the underwriters may
bid for, and purchase, shares of the Class A Common Stock in the open market.
Finally, the representatives, on behalf of the underwriters, also may reclaim
selling concessions allowed to an underwriter or dealer if the underwriting
syndicate repurchases shares distributed by that underwriter or dealer. Any of
these activities may maintain the market price of our Class A Common Stock at a
level above that which might otherwise prevail in the open market. The
underwriters are not required to engage in these activities and, if commenced,
may end any of these activities at any time.
 
  We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act.
 
  The representatives of the underwriters have advised us that the underwriters
do not intend to confirm sales to any account over which they exercise
discretionary authority.
 
  We have applied to list our Class A Common Stock on the NASDAQ National
Market under the symbol "DIGX".
 
  Prior to this offering, there has been no public market for our Common Stock.
Consequently, the initial public offering price for our Common Stock will be
determined by negotiation among the Company and the representatives of the
underwriters. Among the factors to be considered in determining the public
offering price will be:
 
  . prevailing market conditions;
 
  . our results of operations in recent periods;
 
  . the present stage of our development;
 
  . the market capitalizations and stages of development of generally
    comparable companies; and
 
  . estimates of our business potential.
 
  Bear, Stearns & Co. Inc. or its affiliates have provided and may in the
future provide investment banking or other financial services to Intermedia
Communications, Inc., the parent company of Digex, and its affiliates in the
ordinary course of business, for which it has received and is expected to
receive customary fees and expenses. To date, Bear, Stearns has been an initial
purchaser for numerous issuances of securities by Intermedia.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Class A Common Stock offered hereby will be
passed upon for us by Kronish Lieb Weiner & Hellman LLP, New York, New York.
Ralph J. Sutcliffe, a partner of Kronish Lieb Weiner & Hellman LLP,

                         Report of Independent Auditors
 
The Board of Directors and Stockholders
Digex, Incorporated
 
  We have audited the accompanying balance sheets of Digex, Incorporated
(formerly the Web site hosting unit of Business Internet, Inc.) as of December
31, 1997 and 1998, and the related statements of operations, changes in owner's
equity and cash flows for the period from July 7, 1997 (date of acquisition) to
December 31, 1997, and the year ended December 31, 1998. Our audits included
the financial statement schedule listed in the index at Item 16(b). These
financial statements and this schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule 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 Digex, Incorporated at
December 31, 1997 and 1998, and the results of its operations and its cash
flows for the period from July 7, 1997 (date of acquisition) to December 31,
1997 and the year ended December 31, 1998, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.

1. Organization, Basis of Presentation and Significant Accounting Policies
 
Organization
 
  Digex, Incorporated (the "Company") was incorporated on April 27, 1999, under
the laws of the State of Delaware. The Company's business was operated as the
Web site hosting unit of Intermedia Communications Inc. ("Intermedia" or the
"Parent Company") since its acquisition by Intermedia on July 7, 1997. On that
date, Intermedia acquired Business Internet, Inc. (previously known as DIGEX,
Incorporated), of which the Web site hosting unit (the "Predecessor") was a
part, in a business combination accounted for as a purchase. The Web site
hosting unit presented in the accompanying financial statements had no legal
status or existence prior to the incorporation of the Company on April 27,
1999.
 
  The Company commenced operations in January 1996 as a provider of complex Web
hosting services principally to Fortune 2000 companies. The Company's services
include implementing and maintaining secure, scaleable, high-performance Web
sites on the Internet 24 hours a day. In addition, the Company provides a
comprehensive suite of Web management services, including business process
solutions and value-added testing services directed toward improving its
customers' overall Internet performance.
 
Basis of Presentation
 
  The accompanying financial statements of the Company reflect the carved-out
operations and financial position of the Web site hosting unit of Intermedia
for all periods since July 7, 1997. The accompanying financial statements of
the Predecessor reflect its operations and financial position from inception,
January 1, 1996, to July 6, 1997. As more fully discussed in Note 2, "Related
Party Transactions and Corporate Allocations," the financial statements for all
periods presented include allocations of network costs and corporate expenses.
In addition, for financial reporting purposes, the equity activity of the
Company, prior to its incorporation, and the Predecessor has been accumulated
into a single disclosure caption entitled "Owner's Net Investment."
 
  The Company does not expect to generate positive cash flow from its
operations for several years. As a result, the Company intends to seek funding
from external sources. Management of the Company and of Intermedia believe that
the proceeds of the offering described in Note 12 will be sufficient to meet
the Company's projected cash needs into the second half of 2000. In the event
the contemplated offering does not close, Intermedia, as the Company's indirect
parent, will fund the Company's cash requirements for a period of at least one
year. If the proceeds from the contemplated offering are ultimately less than
currently anticipated, management believes the Company can curtail operating
and capital outlays at levels sufficient to support the Company's current
operations. Intermedia will continue to fund the operating and capital
requirements of the Company until consummation of the offering.
 
Significant Accounting Policies
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

1. Organization, Basis of Presentation and Significant Accounting Policies
(Continued)
 
 
 Revenue Recognition and Accounts Receivable
 
  Revenues principally consist of installation fees and monthly service fees
charged to customers under contracts having terms that typically range from one
to three years. Installation fees are recognized upon the customer-approved
completion of the Web Site installation. Monthly service fees are recognized in
the month the service is rendered over the contract period. Certain customer
payments for Web site management services received in advance of service
delivery are deferred until the service is performed. Additional services are
recognized in the month the services are performed.
 
  The Company's accounts receivable are financial instruments that expose the
Company to credit risk, as defined by Statement of Financial Accounting
Standards No. 105, Disclosure of Information About Financial Instruments with
Off-Balance Sheet Risk and Financial Instruments with Concentrations of Credit
Risk (SFAS 105). Accounts receivable are due from commercial entities to whom
credit is extended based on evaluation of the customer's financial condition,
and generally collateral is not required. Anticipated credit losses are
provided for in the financial statements and have been within management's
expectations for all periods presented.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over estimated useful lives of the property and equipment,
generally five years for equipment and up to fifteen years for leasehold
improvements. Equipment acquired under capital leases is amortized using the
straight-line method over the lesser of the lease term or the estimated useful
life of the asset, generally five years. The cost of license agreements with
software vendors is amortized over five years.
 
 Intangible Assets
 
  Intangible assets include assets that arose in connection with the purchase
of Business Internet by Intermedia. Identifiable intangible assets arising from
the purchase are stated at cost and consist of trade name, customer lists,
acquired workforce, developed technology and goodwill. Amortization of these
assets is computed using the straight-line method over the estimated periods of
benefit, generally five years for developed technologies and ten years for all
other intangible assets.
 
 Impairment of Long-Lived Assets
 
  In accordance with Statement on Accounting Standards No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of
(SFAS 121), the Company reviews its long-lived assets for impairment when
events or changes in circumstances indicate the carrying value of such assets
may not be recoverable. This review consists of a comparison of the carrying
value of the asset with the asset's expected future undiscounted cash flows
without interest costs. Estimates of expected future cash flows represent
management's best estimate based on reasonable and supportable assumptions and
projections. If the expected future cash flow exceeds the carrying value of the
asset, no impairment indicator is considered present. If the carrying value
exceeds the future cash flow, an impairment indicator is considered present.
Such impairment would be measured and recognized using a discounted cash flow
method.
 
 Financial Instruments
 
  The carrying amounts reported in the balance sheets for accounts receivable
and accounts payable approximate their fair values.

 Advertising Costs
 
 
  The Company expenses advertising costs as incurred. Advertising expense
amounted to $515, $2,016, $2,076 and $2,544 for the year ended December 31,
1996, the period from January 1, 1997 to July 6, 1997, the period from July 7,
1997 to December 31, 1997, and the year ended December 31, 1998, respectively.
 
 Stock-Based Compensation
 
  Prior to the Company's incorporation, the Company's employees participated in
the stock option plans of Intermedia. The Company accounts for employee stock-
based compensation in accordance with Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees, and related Interpretations,
because the alternative fair value accounting model provided under Statement of
Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation
(SFAS 123), is not required. Accordingly, in cases where exercise prices equal
or exceed fair market value of the underlying Intermedia common stock, the
Company recognizes no compensation expense. In cases where exercise prices are
less than the fair value, compensation is recognized over the period of
performance or vesting period.
 
 Income Taxes
 
  The operations of the Company and of the Predecessor were included in the
consolidated income tax returns of Intermedia and Business Internet,
respectively. For reporting purposes, the Company has used the asset and
liability method in accounting for income taxes, prescribed in Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109),
except that the presentation reflects the parent companies as if they were the
taxing jurisdictions. Under this method, deferred tax assets and liabilities
are determined based on differences between financial reporting and tax bases
of assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.
 
 Comprehensive Income
 
  In June 1997, the FASB issued Statement of Financial Accounting Standards No.
130, Reporting Comprehensive Income (SFAS 130). SFAS 130 requires that total
comprehensive income (loss) be disclosed with equal prominence as net income.
Comprehensive income is defined as changes in stockholder's equity exclusive of
transactions with owners, such as capital contributions and dividends. The
Company and the Predecessor adopted this Standard in 1998 and implemented the
Standard for all years presented herein. The Company's and Predecessor's
comprehensive losses were equal to net losses for all periods presented.
 
 Segment Reporting
 
  The Company and the Predecessor operated during all periods in a single
segment when applying the management approach defined in Statement of Financial
Accounting Standards No. 131, Disclosures about Segments of an Enterprise and
Related Information (SFAS 131).
 
 Pro Forma Earnings (Loss) Per Share
 
  Pro forma basic and diluted net loss per share of the Company has been
calculated using the weighted average common shares and dilutive equivalent
shares issued in connection with the Company's recapitalization assumed
outstanding for all periods of Digex presented.

2. Related Party Transactions and Corporate Allocations
 
  The Predecessor and the Company utilized the central cash management systems
of Business Internet and Intermedia, respectively. Cash requirements during
these periods were satisfied by cash transactions and transfers that were
accounted for through an intercompany account. In addition, the parent
companies charged the Company for identifiable corporate and operating
expenses, such as network cost and for corporate overhead. Intercompany account
balances for all periods presented have been treated as permanent contributions
and have been reflected as a component of owner's net investment in the
accompanying financial statements.

the accompanying financial statements:

of acquisition, the trade name was valued at $11,000. The Company and another
operating unit of Intermedia shared the value of this trade name during the
period from July 7, 1997 through December 31, 1998. Amortization expense
allocated to the Company in the accompanying financial statements was based on
the relative percentage of historical revenues of the Company versus those of
another operating unit of Intermedia. Approximately 24% of the total
amortization during that period is reflected in the accompanying financial
statements.

5. Stock-Based Compensation Arrangements
 
  Under the provisions of the Intermedia 1996 Long-Term Incentive Plan (1996
Plan), certain employees and directors of the Company have been granted options
to buy shares of Intermedia common stock, generally at market value with terms
of five to ten years. Under the provisions of the Business Internet Equity
Participation Plan, employees were awarded stock options, generally at market
value with terms of five years. Options in Business Internet that were held by
employees of the Predecessor were converted into 456,632 Intermedia options in
the 1996 Plan upon the purchase of Business Internet, applying the same terms
and conditions as existed under the Business Internet Equity Participation
Plan.

  At December 31, 1998, the Company's net operating loss carryforward for
federal income tax purposes is approximately $27,400, with expiration periods
beginning in 2011 through 2018. As a result of the recapitalization of the
Company, the net operating loss carryforwards will be limited such that no
benefit will enure to the newly formed corporation.

9. Business Combination
 
  On July 7, 1997, Intermedia purchased the outstanding common stock of
Business Internet, a nationwide Internet services provider and Web site
management company in a business combination accounted for as a purchase. The
purchase price was allocated to the fair values of assets acquired and
liabilities assumed, with the difference recorded as goodwill, which is being
amortized over ten years.
 
  The following table summarizes the allocation of the purchase price to the
acquired assets and assumed net liabilities of the Company:
 
<TABLE>
      <S>                                                           <C>

                                                                    --------
                                                                    $ 47,221
                                                                    ========
</TABLE>
 
  The amount allocated to in-process research and development ("R&D") $15,000
was recorded as a one-time charge to operations in 1997 because the technology
was not fully developed and had no future alternative use.
 
  The purchased in-process research and development related to the Predecessor
related to next generation Web site management services that were valued
utilizing the Exclusion Methodology. Under the Exclusion Methodology, future
revenue streams associated with the incomplete portion of the projects are
excluded from the valuation model. On the date of the purchase, the Company
estimated that the overall state of completion of the projects was
approximately 75% and the expected future costs to complete the projects would
be approximately $100 in the remainder of 1997 and $400 in 1998.
 
  The developed technologies acquired related to the group of servers hosting
customer Web sites located at the Company's Beltsville headquarters. This site
was inadequate to service the increasing number of sites under management by
the Company. The current software used in the Beltsville headquarters at the
time of the purchase had limited functionality and required the integration of
more sophisticated tools to handle complex network management activities. The
in-process research and development was considered to be a significant step
forward since it involved the development, construction, and integration of an
additional Web site management facility on the west coast. This technologically
advanced Web site management facility will incorporate the new software arising
from the Company's joint development efforts with Microsoft Corporation.
Additionally, the west coast facility will incorporate the next generation
routers. These advancements are expected to ultimately result in faster and
easier installation of customers' servers and efficient traffic management with
significantly less overhead.

9. Business Combination (Continued)
 
  On an unaudited pro forma basis, assuming the purchase had occurred at the
beginning of the 1997 year, total revenues would have been $11,612, net loss
would have been $(22,852) and net loss per share (basic and diluted) would have
been $(22.85), assuming that the recapitalization discussed in Note 10 had been
in effect for that period. However, pro forma results do not purport to be
indicative of the results that would have occurred if the acquisition had
occurred at the beginning of year.
 
10. Recapitalization and Affiliate Agreements (Unaudited)
 
Recapitalization
 
  On April 27, 1999, the Company filed its Certificate of Incorporation in the
state of Delaware. Pursuant to the Certificate, the Company is authorized to
issue up to 9,000 shares of $.01 par value common stock, of which 6,000 will be
classified Class A and 3,000 Class B, and 100 shares of Preferred Stock. The
Class A and Class B common stock will be identified in all respects except that
the Class A will be entitled to one vote for each share and the Class B will be
entitled to ten votes for each share. In addition, on that date, Business
Internet contributed the Company's assets to the newly formed corporation.
Liabilities of the Company were retained by Business Internet under this
recapitalization. The unaudited pro forma balance sheet at December 31, 1998
reflects the pro forma effect of this recapitalization.
 
Master Network Services Agreement
 
  Pursuant to a Master Network Services Agreement, to be finalized before
consummation of the offering as described in Note 12, between Intermedia and
the Company, Intermedia will provide Internet network access, as well as
network-related services. The Master Network Agreement has an initial term of
two years, and requires the Company to purchase at least 70% of its non-peering
Internet and network access requirements from Intermedia. Rates charged to the
Company will generally be consistent with rates incurred during the periods
presented in the accompanying financial statements.
 
General and Administrative Services Agreement
 
  Pursuant to a General and Administrative Services Agreement, entered into in
April, 1999, between Intermedia and the Company, Intermedia will provide the
back office and administrative services as listed below:
 
  .Corporate Human Resources, including labor relations, payroll and training
 
  .Treasury Management Services
 
  .Tax services, including tax return preparation
 
  .Facilities management services
 
  .Accounting and back office support services
 
  .Investor relations
 
  .Network engineering services

                  (In thousands, except per share information)
 
 
10. Recapitalization and Affiliate Agreements (Unaudited)
 
  The General and Administrative Services Agreement has an initial term of five
years. Rates charged to the Company for these services are believed to be
consistent with the allocations in the accompanying financial statements. Rates
for services not previously provided to the Company (e.g. investor relations)
are based upon Intermedia and the Company's best estimate of the fair value of
those services.
 
11. Segments
 
  As a provider of Web site hosting service, the Company has one reportable
operating segment. The revenue of this single segment is derived from service
offerings as reported in the Company's statement of operations. Substantially
all of the Company's revenue is attributable to customers in the United States.
Additionally, all of the Company's assets are located within the United States.
 
12. Proposed Public Offering of Common Stock (Unaudited)
 
  The Board of Directors of Intermedia has authorized management of the Company
to file a registration statement with the Securities and Exchange Commission
for the initial public offering of the Company's Class A Common Stock. The
Company contemplates using the proceeds from the proposed public offering to
finance its growth plans.

Item 14. Indemnification of Directors and Officers.
 
  Digex's Certificate of Incorporation provides that Digex shall, to the
fullest extent permitted by the Delaware General Corporation Law (the "DGCL"),
indemnify all persons whom it may indemnify pursuant thereto (i.e., directors
and officers) and shall advance expenses incurred in defending any proceeding
for which such right to indemnification is applicable, provided that, if the
DGCL so requires, the indemnitee provides Digex with an undertaking to repay
all amounts advanced if it is determined by a final judicial decision that such
person is not entitled to indemnification pursuant to this provision. Digex's
Certificate of Incorporation also contains a provision eliminating the personal
liability of Digex's directors for monetary damages for breach of any fiduciary
duty. By virtue of this provision, under the DGCL, a director of Digex will not
be personally liable for monetary damages for breach of his fiduciary duty as a
director, except for liability for (i) any breach of the director's duty of
loyalty to Digex or its stockholders, (ii) acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
dividends or stock purchases or redemptions that are unlawful under the DGCL,
and (iv) any transaction from which a director derives an improper personal
benefit. However, this provision of Digex's Certificate of Incorporation
pertains only to breaches of duty by directors as directors and not in any
other corporate capacity such as officers, and limits liability only for
breaches of fiduciary duties under the DGCL and not for violations of other
laws, such as the federal securities laws. As a result of the inclusion of such
provision, stockholders may be unable to recover monetary damages against
directors for actions taken by them that constitute negligence or gross
negligence or that are in violation of their fiduciary duties, although it may
be possible to obtain injunctive or other equitable relief with respect to such
actions. The inclusion of this provision in Digex's Certificate of
Incorporation may have the effect of reducing the likelihood of derivative
litigation against directors, and may discourage or deter stockholders or
management from bringing a lawsuit against directors for breach of their duty
of care, even though such an action, if successful, might otherwise have
benefited Digex and its stockholders.
 
Item 15. Recent Sales of Unregistered Securities.
 
  As of April 27, 1999, there had been no sales of Digex's unregistered
securities.

Item 17. Undertakings.
 
  The undersigned Registrant hereby undertakes:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by Digex pursuant to Rule 424(b)(1) or (4) or 497(h)
  under the Securities Act shall be deemed to be part of this Registration
  Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new Registration Statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be an initial bona fide offering thereof.
 
    (3) To provide to the Underwriters at the closing specified in the
  underwriting agreements, 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
may be permitted to directors, officers and controlling persons of Digex
pursuant to the foregoing provisions, or otherwise, Digex 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 Digex of expenses incurred or paid by a
director, officer or controlling person of Digex 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, Digex
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 of 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.

                         CERTIFICATE OF INCORPORATION
                                      OF
                              DIGEX, INCORPORATED
                                        
     FIRST:  The name of the corporation is Digex, Incorporated (hereinafter
     -----                                                                  
referred to as the "Corporation").

     SECOND:  The address of the registered office of the Corporation in the
     ------

     -----                                                                   
activity for which a corporation may be organized under the General Corporation
Laws of the State of Delaware as set forth in Title 8 of the Delaware Code (the
"GCL").

     FOURTH:  The total number of shares of stock which the Corporation shall
     ------                                                                  
have authority to issue is 9,100 shares divided into the following classes:

          (i)  6,000 shares of Class A Common Stock, par value $.01 per share
(hereinafter referred to as "Class A Common Stock");

          (ii) 3,000 shares of Class B Common Stock, par value $.01 per share
(hereinafter referred to as "Class B Common Stock"); and

          (iii) 100 shares of Preferred Stock, par value $.01 per share
(hereinafter referred to as "Preferred Stock").

          The Corporation's Class A Common Stock and Class B Common Stock are
referred to hereinafter, collectively, as the "Common Stock."


          A.  Powers and Rights of Holders of Common Stock.
          --  -------------------------------------------- 

          1.  Except as stated in paragraphs 3, 4, 5 and 9 of this Subpart A of
Article FOURTH, the Class A Common Stock and Class B Common Stock shall be
identical in all respects and shall have equal powers, preferences, rights and
privileges.

                                      -1-
<PAGE>
 
          2.  Except as may be otherwise required by law, and subject to the
provisions of any series of Preferred Stock at the time outstanding, the holders
of Class A Common Stock and Class B Common Stock issued and outstanding shall
have and possess the exclusive voting rights and powers, whether at a meeting of
stockholders or in connection with any action taken by written consent.

          3.  Each holder of Class A Common Stock issued and outstanding shall
be entitled to one (1) vote for each share of Class A Common Stock registered in
such holder's name on the books of the Corporation, and each holder of Class B
Common Stock issued and outstanding shall be entitled to ten (10) votes for each
share of Class B Common Stock registered in such holder's name on the books of
the Corporation.  Except as may be otherwise required by law, the holders of the
Class A Common Stock and Class B Common Stock shall vote together as a single
class.

          4.  Any direct or indirect transfer of issued and outstanding shares
of Class B Common Stock other than to a Permitted Holder (as defined herein) or
any event or circumstance as a result of which a holder of Class B Common Stock
ceases to be a Permitted Holder shall result in the automatic conversion of the
shares of Class B Common Stock being transferred to or held by such non-
Permitted Holder into a like number of shares of Class A Common Stock.  No
purported transfer of shares of Class B Common Stock shall be effective unless
and until the transferor has surrendered to the Corporation, at its office or
agency maintained for that purpose, the certificates representing the shares of
Class B Common Stock to be transferred, which certificates shall be duly
endorsed or accompanied by executed stock powers, with the signatures
appropriately guaranteed.  All such certificates shall be accompanied by written
notice of the holder's intention to transfer the shares, including a statement
of the number of shares of Class B Common Stock to be transferred and, if
applicable, converted and the name or names and address or addresses in which
the certificate or certificates for shares of Class B Common Stock or Class A
Common Stock, as the case may be, issuable upon such conversion shall be issued
and, if required, funds for the payment of any applicable transfer taxes. The
Corporation, as soon as practicable thereafter, will deliver at said office to
the transferee of converted shares of Class B Common Stock, or to any nominee or
designee of such transferee, a certificate or certificates for the number of
full shares of Class A Common Stock issuable upon such conversion and, in the
event that the transferor is transferring less than the aggregate number of
shares represented by the certificates surrendered, a certificate or
certificates for the number of full shares of Class B Common Stock not being
transferred.  Shares of Class B Common Stock shall be deemed to have been
converted as of the date of the surrender of the shares for transfer to a non-
Permitted Holder and conversion as hereinbefore provided, or the date on which a
holder of Class B Common Stock ceases to be a Permitted Holder, as the case may
be, and the person or persons in whose name Class A Common Stock is issuable
upon such conversion shall be treated for all purposes as the record holder or
holders of such Class A Common Stock on such date.  

                                      -2-
<PAGE>

Shares of Class B Common Stock so converted shall be returned to the status of
authorized and unissued shares of Class B Common Stock. The Corporation shall at
all times reserve for issuance a number of shares of Class A Common Stock (which
may include Class A Common Stock held by the Corporation as treasury stock)
which shall be sufficient for issuance upon conversion of all of the then
outstanding Class B Common Stock pursuant to this Section 4 or otherwise. The
Corporation as a condition to the transfer or the registration of transfer of
shares of Class B Common Stock to a purported Permitted Holder, may require the
furnishing of such affidavits or other proof as it reasonably deems necessary to
establish that such transferee is a Permitted Holder. For purposes hereof, (a)
"Permitted Holder" shall be defined as Intermedia Communications Inc., or any of
its Affiliates, (b) "Affiliate" shall mean, with respect to any Person, another
Person directly or indirectly controlling, controlled by, or under direct or
indirect common control with, such person, provided, however, that no employee
of the Corporation or any of its subsidiaries shall be deemed to be an Affiliate
solely by reason of his or her capacity as an employee, or by reason of any
employment agreement, and (c) "Person" means and includes an individual, a
partnership, a limited liability company, a joint venture, a corporation, a
trust, an unincorporated organization and a government or any department or
agency thereof. All certificates evidencing shares of Class B Common Stock shall
be endorsed with a legend making appropriate reference to the foregoing
provisions regarding automatic conversion.

          5.  Each holder of Class B Common Stock issued and outstanding shall
be entitled, at such holder's option, to convert shares of Class B Common Stock
registered on the books of the Corporation in such holder's name into a like
number of shares of Class A Common Stock.  If Intermedia Communications Inc. and
its Affiliates shall at any time elect to convert all of the shares of Class B
Common Stock then issued and outstanding and held by them into shares of Class A
Common Stock, whether by transfer pursuant to Section 4 or by conversion
pursuant to this Section 5, all of the other shares of Class B Common Stock
issued and outstanding as of the date of such conversion shall be automatically
converted into shares of Class A Common Stock on a share for share basis and
shall otherwise cease to be outstanding, effective as of the date of such
transfer and/or conversion by Intermedia Communications Inc. and its Affiliates.
All Persons registered as holders of shares of Class B Common Stock on the date
of such conversion shall be treated for all purposes as the record holders of an
equal number of shares of Class A Common Stock on such date.  The Corporation,
as soon as practicable thereafter, will deliver to each of the holders of the
shares of Class B Common Stock converted into shares of Class A Common Stock a
certificate or certificates for the Class A Common Stock against receipt from
such holder of the certificate theretofore representing an equal number of
shares of Class B Common Stock.  Pending delivery of certificates for shares of
Class A Common Stock after such conversion, certificates for shares of Class B
Common Stock so converted shall be deemed to be certificates for an equal number
of shares of Class A Common Stock.

                                      -3-
<PAGE>

          6.  Dividends may be paid to the holders of the Class A Common Stock
and Class B Common Stock, as and when declared by the Board of Directors, out of
any funds of the Corporation legally available for the payment of such
dividends. If and when dividends on the Class A Common Stock and Class B Common
Stock are declared from time to time by the Board of Directors, whether payable
in cash, in property or in shares of stock of the Corporation, the holders of
the Class A Common Stock and Class B Common Stock shall be entitled to share
equally, on a per share basis, in such dividends. If shares of Class B Common
Stock are paid as dividends on Class B Common Stock and shares of Class A Common
Stock are paid as dividends on Class A Common Stock, in an equal amount per
share of Class B Common Stock and Class A Common Stock in proportionate amounts,
such payment will be deemed to be a like dividend or other distribution.

          7.  Subject to the provisions of any series of Preferred Stock at the
time outstanding, upon liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the net assets of the Corporation
shall be distributed to the holders of the Class A Common Stock and Class B
Common Stock, on a pro rata basis, based on the number of shares held by each
such holder, without regard to class.

          8.  If the Corporation shall in any manner split, subdivide, combine
or reclassify any outstanding shares of a class of Common Stock, the outstanding
shares of the other class of Common Stock shall be proportionately split,
subdivided, combined or reclassified in the same manner and on the same basis as
the outstanding shares of the class of Common Stock that have been split,
subdivided, combined or reclassified, unless a different basis has been
consented to by the holders of a majority of the outstanding shares of the class
of Common Stock adversely affected.

          9.  In the event of any corporate merger, consolidation, purchase or
acquisition of property or stock or other reorganization in which any
consideration is to be received by the holders of Class B Common Stock and the
holders of Class A Common Stock, if the consideration shall consist in any part
of voting securities (or of options or warrants to purchase voting securities,
or of securities convertible into or exchangeable for voting securities), the
holders of Class B Common Stock shall receive, on a per share basis, voting
securities with ten times the number of votes per share as those voting
securities to be received by the holders of Class A Common Stock (or options or
warrants to purchase, or securities convertible into or exchangeable for voting
securities with ten times the number of votes per share as those voting
securities upon the exercise of the options or warrants, or into which the
convertible or exchangeable securities may be converted or exchanged, received
by the holder of Class A Common Stock).

          B.  Preferred Stock.
          --  --------------- 

     The Board of Directors is authorized, subject to any limitations prescribed
by law, to provide for the issuance of the shares of Preferred Stock in one or
more series, and by filing a certificate pursuant to the applicable law of the
State of Delaware, to establish from time to time the number of shares to be
included in each such series, and to fix the designation, powers, preferences
and rights of the shares of each such series and any qualifications, limitations
or restrictions thereof. The number of authorized shares of Preferred Stock may
be increased (but not below the number of shares thereof then outstanding) by
the approval of a majority of the votes entitled to be cast by the holders of
the Common Stock, without a vote of the holders of the Preferred Stock, or of
any series thereof, unless a vote of any such holders is required pursuant to
the certificate or certificates establishing the series of Preferred Stock.

     FIFTH:  The following provisions are inserted for the management of the
     -----                                                                  
business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

          A.  The business and affairs of the Corporation shall be managed by or
under the direction of the Board of Directors.  In addition to the powers and
authority expressly conferred upon them by the GCL or by this Certificate of
Incorporation or the Bylaws of the Corporation, the directors are hereby
empowered to exercise all such powers and do all such acts and things as may be
exercised or done by the Corporation.

          B.  The Board of Directors may adopt, amend or repeal the Bylaws of
the Corporation.

          C.  Election of directors need not be by written ballot.

     SIXTH:    The officers of the Corporation shall be chosen in such a manner,
     -----                                                                      
shall hold their offices for such terms and shall carry out such duties as are
determined solely by the Board of Directors, subject to the right of the Board
of Directors to remove any officer or officers at any time with or without
cause.

     SEVENTH:  No director of the Corporation shall be personally liable to the
     -------                                                                   
Corporation or its stockholders for monetary damages for any breach of fiduciary
duty by such a director as a director.  Notwithstanding the foregoing sentence,
a director shall be liable to the extent provided by applicable law (i) for any
breach of the director's duty of loyalty to the Corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the
GCL or (iv) for any transaction from which such director derived an improper
personal benefit.  This Article SEVENTH is also 

                                      -5-
<PAGE>

contained in the Corporation's Bylaws. No amendment to or repeal of this Article
SEVENTH shall apply to or have an effect on the liability or alleged liability
of any director of the Corporation for or with respect to any acts or omissions
of such director occurring prior to such amendment or repeal. If the GCL is
amended hereafter to further eliminate or limit the personal liability of
directors, the liability of a director of the Corporation shall be limited or
eliminated to the fullest extent permitted by the GCL, as amended.
 
     EIGHTH:  A.  Right to Indemnification.  Each person who was or is made a
     ------   ----------------------------                                   
party to or is threatened to be made a party to or is involuntarily involved in
any action, suit or proceeding, whether civil, criminal, administrative or
investigative (a "Proceeding"), by reason of the fact that he or she is or was a
director or officer of the Corporation, or is or was serving (during his or her
tenure as director and/or officer) at the request of the Corporation as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, whether the basis of such Proceeding
is an alleged action or inaction in an official capacity as a director or
officer or in any other capacity while serving as a director or officer, shall
be indemnified and held harmless by the Corporation to the fullest extent
authorized by the GCL (or other applicable law), as the same exists or may
hereafter be amended, against all expense, liability and loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid or to be paid in settlement) reasonably incurred or suffered by such person
in connection with such Proceeding.  Such director or officer shall have the
right to be paid by the Corporation for expenses incurred in defending any such
Proceeding in advance of its final disposition; provided, however, if the GCL
(or other applicable law) requires, the payment of such expenses in advance of
the final disposition of any such Proceeding shall be made only upon receipt by
the Corporation of an undertaking by or on behalf of such director or officer to
repay all amounts so advanced if it should be determined ultimately that he or

prior public disclosure of the date of the meeting is given or made to
stockholders, notice by the stockholder to be timely must be so received not

that nothing in this Section 11 of this Article II shall be deemed to preclude
discussion by 

                                       8
<PAGE>
 
any stockholder of any business properly brought before the annual meeting in
accordance with said procedure.

          The chairman of an annual meeting shall, if the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting in accordance with the provisions of this Section 11 of this
Article II, and if he should so determine, he shall so declare to the meeting
and any such business not properly brought before the meeting shall not be
transacted.

may be made at a meeting of stockholders by or at the direction of the Board of
Directors, by any nominating committee or person appointed by the Board of
Directors or by any stockholder of the corporation entitled to vote for the
election of Directors at the meeting who complies with the notice procedures set
forth in this Section 1 of this Article III.  Such nominations, other than those
made by or at the direction of the Board of Directors, shall be made 

                                       9

pursuant to timely notice in writing to the Secretary of the Corporation. To be
timely, a stockholder's notice shall be delivered to or mailed and received at
the principal executive offices of the Corporation not less than 50 days nor
more than 60 days prior to the meeting; provided, however, that in the event
that less than 50 days' notice or prior public disclosure of the date of the
meeting is given or made to stockholders, notice by the stockholder to be timely
must be so received not later than the close of business on the 10/th/ day
following the day on which such notice of the date of the annual meeting was
mailed or such public disclosure was made. Such stockholder's notice to the
Secretary shall set forth: (a) as to each person whom the stockholder proposes
to nominate for election or re-election as a Director, (i) the name, age,

authority; and (b) as to the stockholder giving the notice (i) the name and
record address of the stockholder, and (ii) the class and number of shares of
capital stock of the Corporation which are beneficially owned by the
stockholder. The Corporation may require any proposed nominee to furnish such
other information as may reasonably be required by the Corporation to determine
the eligibility of such proposed nominee to serve as a Director of the
Corporation. No person shall be eligible for election as a Director of the
Corporation unless nominated in accordance with the procedures set forth herein.
The chairman of the meeting shall, if the facts warrant, determine and declare
to the meeting that a nomination was not made in accordance with the foregoing
procedures, and if he should so determine, he shall so declare to the meeting
and the defective nomination shall be disregarded.

          Section 2.  Number and Election of Directors.  The Board of Directors

originally elected for a term expiring at the annual meeting of stockholders to
be held in 2001, and another class to be originally elected for a term expiring
at the annual meeting of stockholders to be held in 2002, with each class to
hold office until its successor is elected and qualified. At each annual meeting
of the stockholders of the Corporation, the successors of the class of directors
whose term expires at that meeting shall be elected to hold office for a term
expiring at the annual meeting of stockholders held in the third year following
the year of their election. Any director may be removed from office, with or
without cause and only by the affirmative vote of the holders of at least 75% of
the voting power of all the shares of the Corporation entitled to vote generally
in the election of directors, voting together as a single class. Any director
may resign at any time upon notice to the Corporation. Directors need not be
stockholders.

          Section 7.  Actions of Board.  Unless otherwise provided by the
          ---------   ----------------                                   
Certificate of Incorporation or these Bylaws, any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting, if all the members of the Board of Directors or
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board of Directors or
committee.

          Section 8.  Meetings by Means of Conference Telephone. Unless
          ---------   -----------------------------------------

Board of Directors, may participate in a meeting of the Board of Directors or
such committee by means of a conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and such participation in a meeting pursuant to this Section 8 shall
constitute presence in person at such meeting.

          Section 9.  Committees.  The Board of Directors may, by resolution
          ---------   ----------                                            
passed by a majority of the entire Board of Directors, 

                                       15
<PAGE>
 
designate one or more committees, each such committee to consist of one or more
of the directors of the Corporation. The Board of Directors may designate one or
more directors as alternate members of any committee, who may replace any absent
or disqualified member at any meeting of any such committee. In the absence or
disqualification of a member of a committee, and in the absence of a designation
by the Board of Directors of an alternate member to replace the absent or
disqualified member, the member or members thereof present at any meeting and
not disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any absent or disqualified member. Any committee, to the
extent allowed by law and provided in the resolution establishing such
committee, shall have and may exercise all the powers and authority of the Board
of Directors in the management of the business and affairs of the Corporation,
and may authorize the seal of the Corporation to be affixed to all papers which
may require it; but no such committee shall have the power or authority in
reference to amending the Certificate of Incorporation, adopting an agreement of
merger or consolidation, recommending to the stockholders the sale, lease or
exchange of all or substantially all of the Corporation's 

                                       16
<PAGE>
 
property and assets, recommending to the stockholders a dissolution of the
Corporation or a revocation of a dissolution, or amending the Bylaws of the
Corporation; and, unless the resolution or the Certificate of Incorporation
expressly so provides, no such committee shall have the power or authority to
declare a dividend or to authorize the issuance of stock. Each committee shall
keep regular minutes of its meetings and report the same to the Board of
Directors when required.

          Section 10.  Compensation.  Unless otherwise restricted by the
          ----------   ------------                                     
Certificate of Incorporation or these Bylaws, the Board of Directors shall have
the authority to fix the compensation of directors.  The directors may be paid
their expenses, if any, of attendance at each meeting of the Board of Directors
and may be paid a fixed sum for attendance at each meeting of the Board of
Directors or a stated salary as director.  No such payment shall preclude any
director from serving the Corporation in any other capacity and receiving
compensation therefor.  Members of special or standing committees may be allowed
like reimbursement of expenses for attending committee meetings.

          Section 11.  Interested Directors.  No contract or transaction between
          ----------   --------------------                                     
the Corporation and one or more of its directors or officers, or between the
Corporation and any other 

                                       17
<PAGE>
 
corporation, partnership, association, or other organization in which one or
more of its directors or officers are directors or officers, or have a financial
interest, shall be void or voidable solely for this reason, or solely because
the director or officer is present at or participates in the meeting of the
Board of Directors or committee thereof which authorizes the contract or
transaction, or solely because his or their votes are counted for such purpose
if (i) the material facts as to his or their relationship or interest and as to
the contract or transaction are disclosed or are known to the Board of Directors
or their committee, and the Board of Directors or committee in good faith
authorizes the contract or transaction by the affirmative votes of a majority of
the disinterested directors, even though the disinterested directors be less
than a quorum; or (ii) the material facts as to his or their relationship or
interest and as to the contract or transaction are disclosed or are known to the
shareholders entitled to vote thereon, and the contract or transaction is
specifically approved in good faith by vote of the shareholders; or (iii) the
contract or transaction is fair as to the Corporation as of the time it is
authorized, approved or ratified, by the Board of Directors, a committee thereof
or the shareholders. Common or interested directors may be counted in

                                       18

determining the presence of a quorum at a meeting of the Board of Directors or

          Section 12.  Indemnification.  (a)  The Corporation 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 or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Corporation) by reason of the fact that he is or was a director,
officer, employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interest of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its 

                                       19
<PAGE>
 
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

          (b) The Corporation 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 or suit by or in the right of the Corporation to procure a judgment in
its favor by reason of the fact that he is or was a director, officer, employee
or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interest of the Corporation and except that no such indemnification shall
be made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable to the Corporation unless and only to the extent

                                       20
<PAGE>
 
that the Court of Chancery of Delaware or the court in which such action or suit
was brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such Court
of Chancery or such other court shall deem proper.

          (c) To the extent that a director, officer, employee or agent of the
Corporation shall be successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection herewith.

          (d) Any indemnification under paragraphs (a) and (b) (unless ordered
by a court) shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in paragraphs (a) and (b).  Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (2) if such a 

                                       21
<PAGE>
 
quorum is not obtainable, or, even if obtainable a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or (3)
by the stockholders.

          (e) Expenses incurred by an officer or director in defending a civil
or criminal action, suit or proceeding may be paid by the Corporation in advance
of the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
the Corporation as authorized in this Section 12. Such expenses incurred by
other employees and agents may be so paid upon such terms and conditions, if
any, as the Board of Directors deems appropriate.

          (f) The indemnification and advancement of expenses provided by, or
granted pursuant to, the other paragraphs of this Section 12 shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office.

          (g) The Board of Directors may authorize, by a vote of a majority of a
quorum of the Board of Directors, the Corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the Corporation would have the power to indemnify him
against such liability under the provisions of this Section 12.

          (h) For the purposes of this Section 12, references to "the
Corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall 

                                       23
<PAGE>
 
stand in the same position under the provisions of this Section with respect to
the resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.

          (i) For purposes of this Section, references to "other enterprises"
shall include employee benefit plans, references to "fines" shall include any
excise taxes assessed on a person with respect to any employee benefit plan; and
references to "serving at the request of the Corporation" shall include service
as a director, officer, employee or agent of the Corporation which imposes
duties on, or involves services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants or beneficiaries; and
a person who acted in good faith and in a manner he reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the Corporation" as referred to in this Section.

          (j) The indemnification and advancement of expenses provided by, or
granted pursuant to, this Section 12 shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer, 

                                       24
<PAGE>
 
employee or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.
