OUR COMPANY
 
   
     We are a provider of a wide range of hosting and enhanced Internet services
that enable our customers to deploy and manage their Web sites and network-based
applications more effectively than internally developed solutions. Our hosting
services store our customers' Web sites, software applications, and data on
servers typically housed in our data centers so that others on the Internet can
access and interact with our customers' Web sites and network-based
applications. Our Web hosting services provide a variety of hosting solutions to
meet the needs of businesses of all sizes, as their Web sites develop from
low-end marketing brochures to more complex, interactive Web sites and finally
to applications integral to their businesses, or mission-critical. Our
application hosting services provide our customers remote access to
mission-critical software applications and data 24 hours a day, 7 days a week,
365 days a year or 24x7.
    
 
   
     Since our inception in December 1997, we have grown rapidly through the
acquisition of 17 hosting and related Internet service businesses. We provide
Web hosting solutions to more than 47,000 customers, representing more than
79,000 registered Web sites that are actively maintained and used. We also host
more than 10,000 customized Lotus Notes/Domino based applications for more than
1,300 customers. Our pro forma net loss, giving effect to acquisitions completed
to date, was approximately $29.4 million for the year ended December 31, 1998
and our pro forma revenues for that same period were $41.3 million. For the year
ended December 31, 1998 and on a pro forma basis giving effect to acquisitions
completed to date:
    
 
   
     - 28.0% of our revenues were derived from our Web hosting product
       offerings;
    
 
   
     - 51.3% of our revenues were derived from our application hosting product
       offerings;
    
 
   
     - 14.0% of our revenues were derived from consulting services; and
    
 
   
     - 6.7% of our revenues were derived from other services.
    
 
   
     The number of businesses using the Internet is growing rapidly. Many of
these businesses outsource the hosting of their Web sites and software
applications, rather than incur the cost of in-house operations and maintenance.
International Data Corporation or "IDC" estimates that the worldwide market for
Web hosting services will grow from $696 million in 1998 to $10.7 billion by
2002, a 98.0% compounded annual growth rate. In addition, Forrester Research,
Inc. reports that the worldwide market for outsourcing application software
products will grow from approximately $1.0 billion in 1997 to over $21.0 billion
by 2001, a 111.1% compounded annual growth rate. Today, the hosting market is
fragmented, consisting for the most part of:
    
 
     - small local and regional providers who do not have the capital, resources
       or capabilities to provide quality services at competitive prices;
 
     - large national providers who focus on Internet connectivity rather than
       on hosting; and
 
     - consulting and Web design firms for which hosting is not their core
       competency.
 
     We believe that a significant market opportunity exists for a
nationally-recognized hosting solutions provider with the scale and expertise to
offer a wide range of value-priced services to businesses of all sizes. Through
the acquisition and consolidation of hosting and enhanced Internet service
businesses, we believe we can offer a full range of hosting services that enable
businesses to deploy, use, expand and update their Web sites and applications
infrastructures more rapidly and cost-effectively than internally developed
solutions.

     Our service offerings comprise three main areas: Web hosting, application
hosting and consulting.
 
Web Hosting.  Our Web hosting services include the following product offerings:
 
     Virtual Hosting.  Our virtual hosting solution provides Web site hosting on
     a server that is owned, managed and housed by us for multiple customers.
     This is an economical solution for customers with simple or moderately
     accessed sites.
 
     Dedicated Hosting.  Our dedicated hosting solution provides Web site
     hosting on a server that is managed, housed and typically owned by us for a
     single customer. Dedicated server Web hosting enables a customer to host
     complex Web sites and applications without the need to incur significant
     infrastructure and overhead costs. This solution provides greater server
     and network resources for our customers than virtual hosting and allows
     them to configure their hardware to optimize site performance. Companies
     with increasing levels of complexity, traffic or reliance on their Web
     sites may prefer dedicated hosting.
 
   
     Co-located Hosting.  Our co-located hosting solution provides Web hosting
     services on servers that are owned by our customers but which are managed
     and housed by us. In general, the co-located servers are housed separately
     from our shared and dedicated servers in our data centers which we monitor
     on a 24x7 basis and to which we allow customers limited access.
    
 
Application Hosting.  Our application hosting solution, through which we manage
software applications for our customers, is designed to support our customers'
Internet, intranet and extranet projects through a variety of service and
support options, with our primary platform being Lotus Notes/Domino. In
addition, through our strategic alliances with software vendors such as Lotus
and Microsoft, we host applications such as legal automation, sales automation
and distributed learning. We recently began offering ready-made, network-based
software applications that run on a remote server hosted by us, or Internet
rental applications, which allow anyone with a Web browser and an Internet
connection to use sophisticated server-based applications. Our application
hosting services consist of the following solutions:
 
     Groupware Hosting.  Groupware software applications allow people to work
     more closely together while located remotely from each other. We offer a
     range of groupware hosting solutions for the Lotus Notes/Domino platform
     which provides our customers with the infrastructure needed to support the
     following:
 
        - e-mail and other messaging methods for internal and external
          communication;
 
        - project team collaboration and document sharing;
 
        - business process automation and workflow; and
 
        - document libraries.
 
     Application Outsourcing.  We offer a range of application outsourcing
     services which provide our customers with the ability to capitalize on the
     latest Internet-enabled technologies while outsourcing information
     technology operations such as deployment strategies and maintenance and
     upgrades of software to a third party. Our application outsourcing
     offerings include:
 
        - Legal Automation.  Our legal automation solutions package offers our
          customers a suite of collaborative applications that assist corporate
          legal departments and their outside counsel in managing cases,
          budgets, intellectual property and workflow in a secure, reliable
          environment.
 
        - Sales Automation.  Our sales automation solutions package provides
          geographically distributed sales and marketing organizations with all
          the elements needed to quickly deploy a sales automation solution at a
          reasonable cost.
 
        - Distributed Learning.  Our distributed learning solutions offer our
          customers opportunities to deliver online training solutions.
 
Consulting Services.  We provide consulting services to our customers for
intranet, extranet and application hosting solutions, as well as for internal
networking implementations and back-end Web development projects. Consulting
services that we provide include:
 
        - desktop and network server support;
 
                                        2
<PAGE>   8
 
        - network architecture and design;
 
        - strategic technology planning; and
 
        - application development and implementation.
 
     We have two state-of-the-art primary data centers in Atlanta, Georgia and
Houston, Texas and a recently leased facility in Tysons Corner, Virginia. We
house co-located servers in separate limited-access rooms in our Atlanta and
Virginia data centers. In addition, we provide application hosting to our
customers primarily through our Houston data center. Our Atlanta and Houston
data centers are monitored on a 24x7 basis and include:
 
     - sophisticated monitoring and diagnosis;
 
     - 24x7 customer support;
 
     - multiple and high-speed network connections to the Internet; and
 
     - uninterruptible power supply.
 
     We seek to become the industry leader in hosting by providing businesses
with cost-effective, innovative solutions that will allow them to capitalize on
the potential of the Internet. To achieve this objective, our strategy includes
the following key elements:
 
     - Build the Interliant Brand.  We intend to continue to build the
       Interliant brand and strengthen brand recognition by marketing our full
       range of services through an integrated marketing communications program
       including public relations, print and online advertising campaigns and
       other strategic initiatives as well as cooperative promotions with key
       hardware and software vendors.
 
     - Continue Acquisition Program.  By integrating acquired companies, we
       believe we can achieve substantial economies of scale and operating
       efficiencies which will allow us to service customers of all sizes.
       Further, we intend to capitalize on business practices of acquired
       companies that we believe will best maintain our competitive advantage
       and ensure ongoing delivery of high quality hosting services to our
       customers.
 
     - Expand Multiple Sales Channels.  We currently use a variety of sales
       channels to reach our customers including our recently launched business
       partner program. We expect to increase our inbound and outbound telesales
       efforts, which are targeted primarily toward virtual and dedicated
       hosting customers as well as direct sales, which is targeted primarily
       toward co-located hosting customers.
 
     - Leverage the Interliant Customer Base.  We intend to capitalize on the
       enhanced revenue potential of the combined customer bases of our acquired
       companies by leveraging the numerous cross-selling opportunities that our
       expanded line of branded service offerings provides. In this regard, we
       seek to coordinate the selling efforts of our Web hosting, application
       hosting and consulting sales force to increase customer leads and
       referrals.
 
     - Develop Strategic Relationships.  We have established and continue to
       seek strategic relationships that enable us to provide complete, scalable
       and reliable hosting solutions to our customers, resellers and referral
       partners.
 
     On March 10, 1999, we completed the acquisition of substantially all the
assets of Interliant, Inc. In connection with that acquisition, we changed our
name from Sage Networks, Inc. to Interliant, Inc. For purposes of this document
the acquired business of Interliant, Inc. is referred to as Interliant Texas.
Interliant Texas had revenues in 1998 of $21.2 million.
 
   
     Upon completion of this offering, Web Hosting Organization LLC will control
approximately 60.5% of our common stock.
    
 
     Our principal executive offices are located at 215 First Street, Cambridge,
Massachusetts 02142, (617) 374-4700.

                                  RISK FACTORS
 
     Investing in our common stock involves risk. You should carefully consider
the risks and uncertainties described below and elsewhere in this prospectus
before making an investment decision. If any of the following risks or
uncertainties actually occur, our business could be adversely affected. In this
event, the trading price of our common stock could decline, and you could lose
all or a part of your investment.
 
WE HAVE A LIMITED OPERATING HISTORY AND MAY NOT SUCCESSFULLY IMPLEMENT OUR
BUSINESS PLAN.
 
     We have a very limited operating history. We were incorporated in December
1997 and began offering Web hosting services in February 1998. We only recently
completed the acquisition of the application hosting business of Interliant
Texas. As a result, our business model is still in development. Our business and
prospects must be considered in light of the risks frequently encountered by
companies in their early stages of development, particularly companies in the
new and rapidly evolving hosting and enhanced Internet services market. Some of
these risks relate to our ability to:
 
     - build a more comprehensive sales structure to support our business;
 
     - provide reliable and cost-effective services to our customers;
 
     - continue to build our operations and accounting infrastructure to
       accommodate additional customers;
 
     - respond to technological developments or service offerings by our
       competitors;
 
     - develop and offer new, successful products and services or differentiate
       such products and services from those offered by our competitors;
 
     - enter into strategic relationships with application software vendors;
 
     - build, maintain and expand distribution channels; and
 
     - attract and retain qualified personnel.
 
     We may not be successful in addressing these risks, and if we are not
successful, our business could be adversely affected.
 
WE HAVE A HISTORY OF SIGNIFICANT LOSSES AND THESE LOSSES MAY INCREASE IN THE
FUTURE.
 
     Since our inception in December 1997, we have experienced operating losses
and negative cash flows for each quarterly and annual period. As of December 31,
1998 and March 31, 1999, we had an accumulated deficit of approximately $9.9
million and $17.1 million, respectively. We experienced net losses of
approximately $9.7 million in the year ended December 31, 1998 and $7.2 million
in the three months ended March 31, 1999. The revenues and income potential of
our business is unproven, and our limited operating history makes it difficult
to evaluate our prospects. We anticipate increased expenses as we expand our
sales and marketing initiatives to continue to grow the Interliant brand, fund
greater levels of product development, continue to build out our data centers,
implement centralized billing, accounting and customer service systems and
continue our acquisition program.
 
     In addition, we have experienced growth in revenues, primarily attributable
to acquisitions, and we do not believe that this growth rate is necessarily
indicative of future operating results which will depend not only on continuing
our acquisition strategy but also on internal growth. We expect that future
acquisitions will increase our operating expenses and operating losses. As a
result, we expect to incur operating losses for the foreseeable future. We
cannot give any assurance that we will ever achieve profitability on a quarterly
or annual basis, or, if we achieve profitability, that it will be sustainable.
 
                                        6
<PAGE>   12
 
OUR QUARTERLY OPERATING RESULTS ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS. AS A
RESULT, PERIOD-TO-PERIOD COMPARISONS OF OUR RESULTS OF OPERATIONS ARE NOT
NECESSARILY MEANINGFUL AND SHOULD NOT BE RELIED UPON AS INDICATIONS OF FUTURE
PERFORMANCE.
 
     Our quarterly operating results may fluctuate significantly in the future
as a result of a variety of factors, some of which are outside of our control.
These factors include:
 
     - the demand for and market acceptance of our hosting and enhanced Internet
       services;
 
     - our ability to identify, complete and integrate acquisitions to sustain
       growth;
 
     - downward price adjustments by our competitors on services and products
       they offer which are similar to ours;
 
     - changes in the mix of products and services sold by our competitors;
 
     - technical difficulties or system downtime affecting the Internet
       generally or our hosting operations;
 
     - the ability to meet any increased technological demands of our customers;
 
     - the amount and timing of our costs related to our marketing efforts and
       service introductions by us or reseller or referral partners; and
 
     - economic conditions specific to the hosting industry.
 
     Therefore, our operating results for any particular quarter may differ
materially from our expectations or those of security analysts and may not be
indicative of future operating results which may adversely impact the price of
our common stock.
 
THE SUCCESS OF OUR BUSINESS PLAN DEPENDS ON OUR ABILITY TO MAKE ADDITIONAL
ACQUISITIONS.
 
     We intend to pursue opportunities to expand our business through the
acquisition of selected companies in targeted markets. Although we expect to
finance future acquisitions, in part, with some of the proceeds from this
offering and, at a future date with the issuance of additional shares of our
common stock or other debt or equity securities, we cannot guarantee that:
 
     - we will be able to identify appropriate acquisition candidates or
       negotiate acquisitions on favorable terms;
 
     - we will be able to obtain the financing necessary to complete future
       acquisitions; or
 
     - the issuance of our common stock or other securities in connection with
       any future acquisition will not result in a substantial dilution in the
       ownership interests of holders of our common stock.
 
THE SUCCESS OF OUR BUSINESS PLAN DEPENDS ON THE SUCCESSFUL INTEGRATION OF
ACQUISITIONS.
 
   
     Since February 1998, we have acquired 17 businesses, and we are currently
pursuing additional acquisitions. Our future success will depend in large part
on our ability to integrate these businesses or any future acquired businesses
with our existing operations. To integrate these businesses, we will need to:
    
 
     - consolidate their billing and accounting systems into our systems and
       implement financial and other control systems;
 
     - relocate the servers of acquired companies and other equipment to an
       Interliant facility;
 
     - migrate the operations of acquired companies onto our technology
       platforms;
 
     - integrate the customer accounts of acquired companies into our customer
       service system;
 
     - integrate the service offerings of acquired companies into the Interliant
       brand; and
 
     - identify resellers and referral partners of the services of acquired
       companies and migrate them to our business partner program.
 
                                        7
<PAGE>   13
 
   
     The 17 businesses we acquired are in various stages of the integration
process. Our integration plan is constantly changing as a result of our business
activities as well as future acquisitions. We are not able to estimate when, if
at all, all acquired companies will be fully integrated.
    
 
   
THE COSTS ASSOCIATED WITH AND MANAGEMENT RESOURCES DEDICATED TO INTEGRATING
BUSINESSES WE ACQUIRE AND INTERNAL CONTROLS WITH RESPECT TO THOSE ACQUIRED
BUSINESSES MAY ADVERSELY AFFECT OUR BUSINESS.
    
 
     We may not be able to successfully integrate acquired businesses with
existing operations without substantial costs, delays or other problems, if at
all. As we integrate acquired businesses:
 
     - we may lose certain customers of acquired companies due to difficulties
       during the integration process;
 
     - we may not be able to bill customers of the acquired companies accurately
       due to potential deficiencies in the internal controls of the acquired
       Web hosting companies such as inadequate back-office systems of the
       acquired companies and potential difficulties in migrating records onto
       our own systems;
 
     - we may experience difficulty in collecting accounts receivable of
       acquired companies due to inaccurate record keeping of the acquired
       companies;
 
     - key employees of the acquired companies whom we wish to retain may
       resign;
 
     - management's attention and resources could be diverted from our ongoing
       business concerns; and/or
 
     - we may not be able to integrate newly acquired technologies with our
       existing technologies.
 
     Acquisitions also involve a number of other risks, including adverse
effects on our operating results from increases in amortization of intangible
assets, increased compensation expense associated with newly hired employees and
unforeseen liabilities. In addition, any acquired company could significantly
underperform relative to our expectations. In particular, acquired companies
have often experienced modest revenue declines immediately following the closing
of the acquisition. Because we have only recently completed many of our
acquisitions, we are currently facing all of these challenges, and we have not
established our ability to meet them over the long term. As a result of all of
the foregoing, our pursuit of an acquisition strategy could adversely affect our
business.
 
   
OUR RECENT ACQUISITION OF INTERLIANT TEXAS, OUR LARGEST ACQUISITION TO DATE, MAY
ADVERSELY AFFECT OUR BUSINESS IF WE DO NOT SUCCESSFULLY INTEGRATE INTERLIANT
TEXAS OR IF THE COSTS AND MANAGEMENT RESOURCES WE EXPEND IN CONNECTION WITH THE
INTEGRATION EXCEED OUR EXPECTATIONS.
    
 
     In March 1999, we purchased, through a wholly-owned subsidiary,
substantially all the assets, and assumed certain liabilities, of Interliant
Texas, which had revenues of $21.2 million for the year ended December 31, 1998.
Our acquisition of the business of Interliant Texas has been our largest
acquisition to date, and we expect that it will have a continuing, significant
impact on our business. Although we do not currently intend to integrate all the
operations of Interliant Texas into our operations, we still expect to incur
significant integration costs. In addition, the following factors could increase
the costs of integration:
 
     - unexpected employee turnover;
 
     - delays in addressing duplicate operations; and
 
     - additional fees and charges to obtain consents, regulatory approvals or
       permits.
 
     Further, we cannot guarantee that we will realize the benefits or strategic
objectives we are seeking to obtain by acquiring Interliant Texas. Costs
associated with this acquisition that exceed our expectations would have an
adverse effect on our business.
 
                                        8
<PAGE>   14
 
   
A SIGNIFICANT PORTION OF OUR ASSETS CONSISTS OF INTANGIBLE ASSETS, THE
RECOVERABILITY OF WHICH IS NOT CERTAIN AND THE AMORTIZATION OF WHICH WILL
INCREASE LOSSES OR REDUCE EARNINGS IN THE FUTURE.
    
 
   
     In connection with all of our acquisitions completed to date, $85.2 million
of the aggregate purchase price has been allocated to intangible assets such as
covenants not to compete, customer lists, trade names, assembled work force and
goodwill. Annual amortization of these intangible assets will amount to
approximately $15.4 million and will increase as we acquire additional business.
Our business could suffer if changes in our industry or our inability to operate
the business successfully and produce positive cash flows from operations result
in an impairment in the value of our intangible assets and therefore necessitate
a write-off of all or part of these assets.
    
 
OUR APPLICATION HOSTING SOLUTIONS DEPEND ON SOFTWARE APPLICATIONS PROVIDED TO US
UNDER AGREEMENTS WE HAVE WITH APPLICATION SOFTWARE VENDORS.
 
     We obtain software products pursuant to agreements with Lotus and Microsoft
and package them as part of our application hosting solutions. The agreements
are typically for terms ranging from one to three years. If these agreements
were terminated or not renewed, we might have to discontinue products or
services that are central to our business strategy or delay their introduction
unless we could find, license and package equivalent technology. Our business
strategy also depends on obtaining additional application software. We cannot be
sure, however, that we will be able to obtain the new and enhanced applications
we may need to keep our solutions competitive. If we cannot obtain these
applications and as a result must discontinue, delay or reduce the availability
of our solutions or other products and services, our business may be adversely
affected.
 
OUR AGREEMENTS WITH APPLICATION SOFTWARE VENDORS ARE NOT EXCLUSIVE AND MAY NOT
PROVIDE US WITH ANY COMPETITIVE ADVANTAGE.
 
     None of our third-party agreements are exclusive. Our competitors may also
license and utilize the same technology in competition with us. We cannot be
sure that the vendors of technology used in our products will continue to
support this technology in its current form. Nor can we be sure that we will be
able to adapt our own products to changes in this technology. In addition, we
cannot be sure that the financial or other difficulties of third party vendors
will not have an adverse affect on the technologies incorporated in our
products, or that, if these technologies become unavailable, we will be able to
find suitable alternatives.
 
WE DEPEND ON OUR RESELLER SALES CHANNEL TO MARKET AND SELL MANY OF OUR SERVICES.
 
     We rely significantly on resellers to market and sell our services. We
estimate that as of December 31, 1998 approximately 16% of our active hosted
domains were maintained by resellers. For this purpose, we include as resellers
any entity which has three or more active domains hosted by us. Our failure to
maintain and grow our reseller sales channel may adversely affect our business.
Our agreements with resellers generally do not require that the resellers sell
any minimum level of our services and do not restrict the resellers' development
or sale of competitive services. We have very little control over whether these
resellers will dedicate resources or give priority to selling our services.
 
     We will need to continue to deliver reliable service and keep our reseller
pricing and support programs competitive. If we succeed in increasing our sales
through resellers, we may lose brand identification and brand loyalty, since our
services may not be identified by the Interliant brand or may be marketed
differently by our resellers.
 
WE ONLY RECENTLY BEGAN TO OFFER MANY OF OUR PRODUCTS AND SERVICES. IF THEY ARE
NOT ACCEPTED BY THE MARKET OR HAVE RELIABILITY OR QUALITY PROBLEMS OUR BUSINESS
MAY SUFFER.
 
     We have recently introduced new hosting solutions such as providing our
customers with integrated text, graphics, video, information and sound
capabilities on their Web sites, or multimedia hosting and providing our
customers with the ability to rent software applications instead of purchasing
them as well as
                                        9
<PAGE>   15
 
enhanced Internet services such as e-commerce and consulting services. If these
and other new hosting solutions and enhanced Internet services fail to gain
market acceptance, our business could be adversely affected. In addition, if
these newly introduced hosting solutions and enhanced Internet services have
reliability, quality or compatibility problems, market acceptance of these
products could be greatly hindered and our ability to attract new customers
could be adversely affected. We cannot offer any assurance that these new
solutions and services are free from any reliability, quality or compatibility
problems.
 
THE EXPECTED CONTINUED GROWTH IN THE MARKET FOR OUR PRODUCTS AND SERVICES MAY
NOT MATERIALIZE.
 
     Our market is new and rapidly evolving. Whether the market for our products
and services will continue to grow is uncertain. Our business would be adversely
affected if the hosting market does not continue to grow or if businesses prove
to be unwilling to outsource their hosting business.
 
     Our success depends in part on continued growth in the use of the Internet.
Our business would be adversely affected if Web usage does not continue to grow.
Web usage may be inhibited for a number of reasons, such as:
 
     - security and privacy concerns;
 
     - uncertainty of legal and regulatory issues concerning the use of the
       Internet;
 
     - inconsistent quality of service; and
 
     - lack of availability of cost-effective, high-speed connectivity.
 
OUR RAPID GROWTH AND EXPANSION HAS AND MAY CONTINUE TO SIGNIFICANTLY STRAIN OUR
RESOURCES.
 
   
     We are currently experiencing rapid growth, primarily due to our
acquisition of 17 businesses since February 1998. In addition, from inception we
have grown to 500 employees, which includes 19 employees on a contract basis.
This rapid growth of our business and our product and service offerings has
placed, and is likely to continue to place, a significant strain on our
operating and financial resources. Our future performance will partly depend on
our ability to manage our growth effectively, which will require that we further
develop our operating and financial system capabilities and controls. We have
invested, and intend to continue to invest, significant amounts in billing,
accounts receivable, customer service and financial systems which we believe,
once implemented, will be able to produce timely, accurate and consistent
information as our business continues to grow. However, because we employ a
strategy that includes a high level of acquisition activity, at any time there
are likely to be one or more operating businesses that have not been fully
integrated into our core systems and continue to produce financial and other
information from their existing systems. As a result, our ability to record,
process, summarize and report financial data could be adversely affected.
    
 
WE DEPEND ON THE GROWTH AND STABILITY OF THE INTERNET INFRASTRUCTURE.
 
     If the use of the Internet continues to grow, its infrastructure may not be
able to support the demands placed on it by such growth and its performance or
reliability may decline. In addition, Web sites have experienced interruptions
in their service as a result of outages and other delays occurring throughout
the Internet network infrastructure. If these outages or delays occur
frequently, use of the Internet as a commercial or business medium could, in the
future, grow more slowly or decline which would adversely affect our business.
 
WE DEPEND ON OUR NETWORK INFRASTRUCTURE. IF WE DO NOT HAVE CONTINUED ACCESS TO A
RELIABLE NETWORK, OUR BUSINESS WILL SUFFER.
 
     Our success partly depends upon the capacity, scalability, reliability and
security of our network infrastructure, including the capacity leased from our
telecommunications network suppliers such as UUNET Technologies, Inc. We depend
on these companies to provide uninterrupted and "bug free"
 
                                       10
<PAGE>   16
 
service and would be adversely affected if such services were not provided. In
addition, we would be adversely affected if such companies greatly increased the
prices of their services or if the telecommunications capacity available to us
was insufficient for our business purposes and we were unable to use alternative
networks or pass along any increased costs to our customers.
 
OUR BUSINESS AND EXPANSION MODELS ASSUME THAT WE WILL BE ABLE TO EASILY SCALE
OUR NETWORK INFRASTRUCTURE TO SUPPORT INCREASING NUMBERS OF CUSTOMERS AND
INCREASED TRAFFIC. HOWEVER, THE SCALABILITY OF OUR NETWORK IS UNPROVEN.
 
     We must continue to develop and expand our network infrastructure as the
number of users and the amount of information they wish to transport as well as
the number of products and services we offer increases and to meet changing
customer requirements. Our expansion and adaptation of our telecommunications
and hosting facility infrastructure will require substantial financial,
operational and management resources. If we are required to expand our network
significantly and rapidly due to increased usage, additional stress will be
placed upon our network hardware, traffic management systems and hosting
facilities. Due to the limited deployment of our services to date, the ability
of our network to connect and manage a substantially larger number of customers
at high transmission speeds while maintaining superior performance is unknown.
 
     As our customers' bandwidth usage increases, we will need to make
additional investments in our infrastructure to maintain adequate data
transmission speeds, the availability of which may be limited and the cost of
which may be significant. Additional network capacity may not be available from
third-party suppliers as it is needed by us. As a result, our network may not be
able to achieve or maintain a sufficiently high capacity of data transmission,
especially if customers' usage increases. Any failure on our part to achieve or
maintain high-capacity data transmission could significantly reduce consumer
demand for our services and adversely affect our business.
 
WE COULD EXPERIENCE SYSTEM FAILURES AND CAPACITY CONSTRAINTS, WHICH COULD AFFECT
OUR ABILITY TO COMPETE.
 
     To succeed, we must be able to operate our network infrastructure on a 24x7
basis without interruption. Our operations depend upon our ability to protect
our network infrastructure, equipment and customer files against damage from:
 
     - human error;
 
     - various natural disasters;
 
     - power loss or telecommunications failures; and
 
     - sabotage or other intentional acts of vandalism.
 
     However, even if we take precautions, the occurrence of a natural disaster
or other unanticipated problems at our data centers could result in
interruptions in the services we provide to our customers.
 
     At this time, we do not have a formal disaster recovery plan. Although we
believe that our Atlanta and Houston data centers are state-of-the-art and have
sufficient system protections in place to ensure high quality service with
minimal interruptions, we estimate that currently only approximately 34% of our
customers are hosted in these data centers. In addition, we may not integrate
into our Network Operations Centers all the data centers of companies we
acquire. Therefore, in some instances, our network reliability may be
compromised. Although we have attempted to build redundancy into our network and
hosting facilities, our data centers are currently subject to various single
points of failure. As a result, a problem with one of our routers, switches or
fiber paths could cause an interruption in the services we provide to some of
our customers. We have experienced interruptions in service in the past. Any
future interruptions could:
 
     - require us to spend substantial amounts of money replacing existing
       equipment or adding redundant facilities;
 
                                       11
<PAGE>   17
 
     - damage our reputation for reliable service;
 
     - cause existing end users, resellers and referral partners to cancel their
       contracts;
 
     - cause end users to seek damages for losses incurred; or
 
     - make it more difficult for us to attract new end users, resellers and
       referral partners.
 
     Any of these occurrences could adversely affect our business.
 
     We have entered into service level agreements with some of our customers,
and we anticipate that we will offer service level agreements to a larger group
of customers in the future. In that case, we could incur significant liability
to our customers in connection with any system downtime and those obligations
may adversely affect our business.
 
IF WE DO NOT RESPOND EFFECTIVELY AND ON A TIMELY BASIS TO RAPID TECHNOLOGICAL
CHANGE, OUR BUSINESS COULD SUFFER.
 
     The Internet industry is characterized by rapidly changing technology,
industry standards, customer needs and competition, as well as by frequent new
product and service introductions. Our future success will depend, in part, on
our ability to accomplish all of the following in a timely and cost-effective
manner, all while continuing to develop our business model and roll-out our
services on a national level:
 
     - effectively use and integrate leading technologies;
 
     - continue to develop our technical expertise;
 
     - enhance our products and current networking services;
 
     - develop new products and services that meet changing customer needs;
 
     - advertise and market our products and services; and
 
     - influence and respond to emerging industry standards and other changes.
 
     We cannot assure you that we will successfully use or develop new
technologies, introduce new services or enhance our existing services on a
timely basis, or that new technologies or enhancements used or developed by us
will achieve market acceptance. Our pursuit of necessary technological advances
may require substantial time and expense.
 
OUR FAILURE TO DEVELOP BRAND RECOGNITION FOR THE INTERLIANT BRAND COULD HURT OUR
BUSINESS.
 
     Upon acquiring Interliant Texas and its application hosting business, we
began the process of offering the full range of our hosting products and
enhanced Internet services under the Interliant brand. We are currently
marketing and expect to continue to market many of our products and services
under the Sage Networks brand and the brand names of acquired companies. Our
sales and marketing expenses were $2.6 million in the year ended December 31,
1998 and $1.9 million in the three months ended March 31, 1999. A key component
of our strategy is to significantly increase our sales and marketing activities.
This will include the expansion of our sales force, development of reseller and
referral partner channels and increased marketing efforts. As a result, sales
and marketing expenses will increase substantially in future periods. We expect
sales and marketing expenses for the year ending December 31, 1999 to exceed
$20.0 million. Our business could be adversely affected if the Interliant brand
is not well received by our customers, our marketing efforts are not productive
or we are otherwise unsuccessful in increasing our brand awareness.
 
WE OPERATE IN AN EXTREMELY COMPETITIVE MARKET AND MAY NOT BE ABLE TO COMPETE
EFFECTIVELY.
 
     Our current and prospective competitors are numerous. Many of our
competitors have substantially greater financial, technical and marketing
resources, larger customer bases, longer operating histories,
 
                                       12
<PAGE>   18
 
greater name recognition and more established relationships in the industry than
we do. Our current and prospective competitors generally may be divided into the
following groups:
 
     - other Web hosting and Internet services companies such as AboveNet
       Communications, Inc., Exodus Communications, Inc., Frontier GlobalCenter,
       Globix Corporation and local and regional hosting providers;
 
     - national and regional Internet service providers such as Concentric
       Network Corporation, MindSpring Enterprises, Inc., UUNET Technologies,
       Inc., PSINet Inc. and Verio Inc.;
 
     - global telecommunications companies including AT&T Corp., British
       Telecommunications plc, Telecom Italia SpA and Nippon Telegraph and
       Telephone Corp.;
 
     - regional and local telecommunications companies, including the regional
       Bell operating companies such as Bell Atlantic Corporation and US West,
       Inc.;
 
     - companies that focus on application hosting such as USinternetworking,
       Inc. and IBM Global Services; and
 
     - multimedia hosting companies such as broadcast.com.
 
WE DEPEND ON THE SKILLS OF KEY PERSONNEL.
 
     We are dependent on the continued service of our key personnel, including:
 
     - Leonard J. Fassler and Bradley A. Feld, our Co-Chairmen;
 
     - Stephen W. Maggs, our Chief Executive Officer and President;
 
     - James M. Lidestri, our Executive Vice President;
 
     - Rajat Bhargava, our Senior Vice President, Strategic Planning and
       Integration; and
 
     - William A. Wilson, our Chief Financial Officer.
 
     We recently entered into one-year employment agreements with Messrs.
Fassler, Maggs and Bhargava and a one-year consulting agreement with Mr. Feld
through Intensity Ventures, Inc. In addition, in connection with our acquisition
of Interliant Texas, we entered into a two-year employment agreement with Mr.
Lidestri. The loss of the services of one or more of these people could
adversely affect our business.
 
     Our Co-Chairmen, Bradley A. Feld and Leonard J. Fassler, are each currently
active in, and serve as directors and/or executive officers of, a number of
businesses other than Interliant. Although Mr. Feld spends approximately half of
his time and Mr. Fassler spends substantially all of his time at Interliant, and
both are active in its management, neither is contractually committed to spend
any specific amount of time at Interliant. If Mr. Feld or Mr. Fassler were to
significantly reduce the time they devoted to Interliant, our business may be
adversely affected.
 
WE OPERATE IN AN INDUSTRY WHERE IT IS DIFFICULT TO ATTRACT AND RETAIN QUALIFIED
PERSONNEL.
 
     We expect that we will need to hire additional personnel in all areas of
our business. The competition for personnel throughout our industry is intense.
At times, we have experienced difficulty in attracting qualified new personnel.
If we do not succeed in attracting new, qualified personnel or retaining and
motivating our current personnel, our business could suffer.
 
WE MAY NEED ADDITIONAL FUNDS WHICH, IF AVAILABLE COULD RESULT IN AN INCREASE IN
OUR INTEREST EXPENSE OR DILUTION OF YOUR SHAREHOLDINGS. IF THESE FUNDS ARE NOT
AVAILABLE, OUR BUSINESS COULD BE HURT.
 
     We currently anticipate that our available cash resources combined with the
net proceeds from this offering will be sufficient to fund our acquisition
program, the expansion of our sales and marketing program, completion of our
data centers and our other operating needs through the end of 1999.
                                       13
<PAGE>   19
 
Thereafter, we expect to require additional financing. At this time, we do not
have any credit facility or other working capital credit line under which we may
borrow funds for working capital or other general corporate purposes. If our
plans or assumptions change or are inaccurate, we may be required to seek
additional capital or seek capital sooner than anticipated. We may need to raise
funds through public or private debt or equity financing.
 
     If funds are raised through the issuance of equity securities, the
percentage ownership of our then current stockholders may be reduced and such
equity securities may have rights, preferences or privileges senior to those of
the holders of our common stock. If additional funds are raised through the
issuance of debt securities, such securities would have certain rights,
preferences and privileges senior to those of the holders of our common stock
and the terms of such debt could impose restrictions on our operations. If
additional funds become necessary, additional financing may not be available on
terms favorable to us, or at all. If adequate funds are not available on
acceptable terms, we may not be able to continue to fund our operations and
growth or to continue our acquisition program. Our inability to raise capital
could adversely affect our business.
 
   
CURRENCY FLUCTUATIONS AND DIFFERENT STANDARDS, REGULATIONS AND LAWS RELATING TO
OUR INTERNATIONAL OPERATIONS MAY ADVERSELY AFFECT OUR BUSINESS.
    
 
   
     On a pro forma basis, giving effect to acquisitions completed to date,
approximately 18.5% of our dollar amount of billings for the year ended December
31, 1998 and 19.8% for the three months ended March 31, 1999 were to customers
located outside the United States, primarily in Europe, Asia and South America.
    
 
   
     Our success may depend in part on expanding our international presence.
Because our sales overseas are denominated in U.S. dollars, currency
fluctuations may inhibit us from marketing our services to potential foreign
customers or collecting for services rendered to current foreign customers. In
addition different privacy, censorship and service provider liability standards
and regulations and different intellectual property laws in non-U.S. countries
may adversely affect our business.
    
 
   
DISRUPTION OF OUR SERVICES DUE TO ACCIDENTAL OR INTENTIONAL SECURITY BREACHES
MAY ADVERSELY IMPACT OUR BUSINESS.
    
 
     A significant barrier to the growth of e-commerce and communications over
the Internet has been the need for secure transmission of confidential
information. Despite our design and implementation of a variety of network
security measures, unauthorized access, computer viruses, accidental or
intentional actions and other disruptions could occur. We may incur significant
costs to protect against the threat of security breaches or to alleviate
problems caused by such breaches. If a third person were able to misappropriate
our users' personal or proprietary information or credit card information, we
could be subject to claims, litigation or other potential liabilities.
 
   
NEW LAWS AND REGULATIONS WHICH IMPACT OUR INDUSTRY COULD HARM OUR BUSINESS.
    
 
     We are not currently subject to direct regulation by the Federal
Communications Commission or any other governmental agency, other than
regulations applicable to businesses in general. However, in the future, we may
become subject to regulation by the FCC or another regulatory agency. Our
business could suffer depending on the extent to which our activities are
regulated or proposed to be regulated.
 
   
WE OPERATE IN AN UNCERTAIN REGULATORY AND LEGAL ENVIRONMENT WHICH MAY MAKE IT
MORE DIFFICULT TO DEFEND OURSELVES AGAINST ANY CLAIMS BROUGHT AGAINST US.
    
 
     While there are currently few laws or regulations which specifically
regulate Internet communications, laws and regulations directly applicable to
online commerce or Internet communications are becoming more prevalent. There is
much uncertainty regarding the marketplace impact of these laws. In addition,
various jurisdictions already have enacted laws covering intellectual property,
privacy, libel and taxation that could affect our business by virtue of their
impact on online commerce. Further, the growth of the
                                       14
<PAGE>   20
 
Internet, coupled with publicity regarding Internet fraud, may lead to the
enactment of more stringent consumer protection laws. If we become subject to
claims that we have violated any laws, even if we successfully defend against
these claims, our business could suffer. Moreover, new laws that impose
restrictions on our ability to follow current business practices or increase our
costs of doing business could hurt our business.
 
   
IF STATES AND COUNTRIES IN WHICH WE DO NOT CURRENTLY COLLECT SALES OR OTHER
TAXES MANDATE THAT WE DO SO, OUR BUSINESS COULD SUFFER.
    
 
     We currently do not collect sales or other taxes with respect to the sale
of services or products in states and countries where we believe we are not
required to do so. We do collect sales and other taxes in the states and
countries in which we have offices and are required by law to do so. One or more
jurisdictions have sought to impose sales or other tax obligations on companies
that engage in online commerce within their jurisdictions. A successful
assertion by one or more jurisdictions that we should collect sales or other
taxes on our products and services, or remit payment of sales or other taxes for
prior periods, could have an adverse effect on our business.
 
WE COULD FACE LIABILITY FOR INFORMATION DISSEMINATED THROUGH OUR NETWORK.
 
     It is possible that claims could be made against online services companies
and Internet service providers in connection with the nature and content of the
materials disseminated through their networks. Several private lawsuits are
pending against other entities which seek to impose liability upon online
services companies and Internet service providers as a result of the nature and
content of materials disseminated over the Internet. If any of these actions
succeed, we might be required to respond by investing substantial resources or
discontinuing some of our service or product offerings. The increased attention
focused upon liability issues as a result of these lawsuits and legislative
proposals could impact the growth of Internet use. Although we carry
professional liability insurance, it may not be adequate to compensate or may
not cover us in the event we become liable for information carried on or
disseminated through our networks. Any costs not covered by insurance incurred
as a result of such liability or asserted liability could adversely affect our
business.
 
WE DEPEND ON THE PROTECTION AND ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS.
 
   
     We currently license and may in the future license certain technologies
from third parties, which may subject us to infringement actions based upon the
technologies licensed from these third parties. Any of these claims, with or
without merit, could subject us to costly litigation and divert the attention of
our technical and management personnel. These third-party technology licenses
may not continue to be available to Interliant on commercially reasonable terms.
The loss of the ability to use such technology could require Interliant to
obtain the rights to use substitute technology, which could be more expensive or
offer lower quality or performance, and therefore have a material adverse effect
on Interliant's business.
    
 
OUR COMPUTER SYSTEMS AND THOSE OF THIRD PARTIES WITH WHOM WE DO BUSINESS MAY NOT
BE YEAR 2000 COMPLIANT, WHICH MAY CAUSE SYSTEM FAILURES AND DISRUPTIONS OF
OPERATIONS.
 
     Currently, many computer and software products are coded to accept
two-digit entries in the date code field. These date code fields will need to
accept four-digit entries to distinguish 21st century dates from 20th century
dates. As a result, many companies' software and computer systems, including
ours, may need to be upgraded or replaced in order to comply with Year 2000
requirements. We recognize the need to ensure that our operations will not be
adversely impacted by Year 2000 software and computer system failures.
 
     We have made a preliminary assessment of the Year 2000 readiness of our
information technology systems. In addition, we are currently seeking assurances
from our material hardware and software vendors that their products are Year
2000 compliant. Until such process is complete, we will not be able to
completely evaluate whether our information technology systems will need to be
revised or replaced.
 
                                       15
<PAGE>   21
 
Although we have not incurred any material expenditures in connection with
identifying or evaluating Year 2000 compliance issues to date, we do not at this
time possess the information necessary to estimate the potential costs of
revisions or replacements to our software and systems or third party software,
hardware or services that are determined not to be Year 2000 compliant. Such
expenses, if higher than anticipated, could have a material adverse effect on
our business.
 
     Although we are not currently aware of any Year 2000 compliance problems
relating to our information technology systems that would have a material
adverse effect on our business, there is no assurance that we will not discover
any such compliance problems. Our failure to fix or replace our software,
hardware or services on a timely basis could result in lost revenues, increased
operating costs and the loss of customers and other business interruptions, any
of which could have a material adverse effect on our business. Moreover, the
failure to adequately address Year 2000 compliance issues in our information
technology systems could result in claims of mismanagement, misrepresentation or
breach of contract and related litigation, which could be costly and
time-consuming to defend.
 
OUR STOCK PRICE MAY BE VOLATILE.
 
     There has not been a public market for our common stock. We cannot predict
the extent to which investor interest in Interliant will lead to the development
of a trading market or how liquid that market might become. Further, we cannot
guarantee that the price of our common stock will not decline below the initial
public offering price. Stock prices of technology companies, especially
Internet-related companies, have been highly volatile. The initial public
offering price may not be indicative of prices that will prevail in the trading
market. Various factors could cause the market price of our common stock to
fluctuate substantially. These factors may include:
 
     - variations in our revenue, earnings and cash flow;
 
     - announcements of new service offerings, technological innovations or
       price reductions by us, or our competitors or providers of alternative
       services; and
 
     - changes in analysts' recommendations or projections and general economic
       and market conditions.
 
     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 a company. Such litigation could result in substantial
costs and a diversion of management's attention and resources and could have a
material adverse effect on our business.
 
   
WEB HOSTING ORGANIZATION LLC WILL CONTROL APPROXIMATELY 60.5% OF OUR COMMON
STOCK AFTER THIS OFFERING, AND ITS INTERESTS MAY BE IN CONFLICT WITH THOSE OF
INTERLIANT AND THE OTHER STOCKHOLDERS.
    
 
     Immediately following this offering, Web Hosting Organization LLC will
control approximately 60.9% of our outstanding common stock. Accordingly, Web
Hosting Organization LLC will be able to control any stockholder vote, including
any vote on the election of directors. The members of Web Hosting Organization
LLC are affiliates of Charterhouse Group International, Inc. and the WHO
Management LLC, of which Interliant's Co-Chairmen, Leonard J. Fassler and
Bradley A. Feld, are the member managers. Web Hosting Organization LLC's
interests could conflict with the interests of our other stockholders. See
"Description of Capital Stock -- The WEB Hosting Organization Investment" and
"Related Party Transactions."
 
     Charterhouse Equity Partners III, L.P., which is an affiliate of
Charterhouse Group International, Inc., has the ability to control our direction
and future operations through its significant equity ownership of Web Hosting
Organization LLC. Certain decisions concerning our operations or financial
structure may present conflicts of interest between Charterhouse and our other
stockholders. In addition to its investments in us, Charterhouse or its
affiliates may in the future invest in other entities engaged in the hosting
business or other Internet-related business. As a result, Charterhouse or its
affiliates have, and may develop, relationships with businesses that are or may
be competitive with us. Conflicts may also arise in the negotiation or
enforcement of arrangements entered into by us and entities in which
Charterhouse has
                                       16
<PAGE>   22
 
an interest. Such conflicts of interest could cause Charterhouse to use its
significant ownership interest to force us to act in a manner adverse to the
interests of our other stockholders.
 
OUR STOCK PRICE MAY BE AFFECTED BY THE AVAILABILITY OF SHARES FOR SALE IN THE
NEAR FUTURE. THE FUTURE SALE OF LARGE AMOUNTS OF OUR STOCK, OR THE PERCEPTION
THAT SUCH SALES COULD OCCUR, COULD NEGATIVELY AFFECT OUR STOCK PRICE.
 
   
     The market price of the common stock could drop as a result of sales of a
large number of shares of common stock in the market after this offering. There
will be 41,663,045 shares of common stock outstanding immediately after this
offering. The 7,000,000 shares of common stock sold in this offering will be
freely tradable without restriction or further registration under the Securities
Act of 1933, as amended, unless such shares are held by "affiliates" of
Interliant, as that term is defined in Rule 144 under the Securities Act.
    
 
   
     Of the remaining 34,663,045 shares of common stock 34,621,085 are subject
to restrictions under Rule 144 of the Securities Act. Holders of 32,320,790
restricted shares have registration rights with respect to such shares. However,
such shares are subject to lock-up agreements pursuant to which the holders of
these shares have agreed, subject to certain limited exceptions, not to sell or
otherwise dispose of any of their shares for a period of 180 days after the date
of this prospectus, or exercise their registration rights, without the prior
written consent of Merrill Lynch & Co., Inc. See "Shares Eligible for Future
Sale."
    
 
   
     At the time of this offering, 3,649,234 shares of common stock issuable
upon exercise of options issued as compensation will also become available for
resale in the public market at prescribed times. We also intend to register
under the Securities Act the shares of common stock reserved for issuance under
our stock option plan. See "Shares Eligible for Future Sale."
    
 
FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS.
 
     This prospectus contains certain forward-looking statements, relating to,
among other things, future results of operations, growth plans, sales, gross
margin and expense trends, capital requirements and general industry and
business conditions applicable to Interliant. These forward-looking statements
are based largely on Interliant's current expectations and are subject to a
number of risks and uncertainties. When used in this prospectus, the words
"anticipate," "believe," "estimate" and similar expressions are generally
intended to identify forward-looking statements. Actual results could differ
materially from these forward-looking statements. In addition to the other risks
described elsewhere in this "Risk Factors" discussion, important factors to
consider in evaluating such forward-looking statements include changes in
external competitive market factors, changes in Interliant's business strategy
or an inability to execute its strategy due to unanticipated changes in the
hosting industry or the economy in general and various other competitive factors
that may prevent Interliant from competing successfully in existing or future
markets. In light of these risks and uncertainties, there can be no assurance
that the forward-looking statements contained in this prospectus will be in fact
realized.

                                USE OF PROCEEDS
 
     We estimate that we will receive net proceeds from the sale of 7,000,000
shares in this offering of approximately $63.7 million assuming an initial
public offering price of $10.00 and, after deduction of underwriting discounts
and commissions and expenses payable by us, estimated at $6.3 million.
 
     We currently intend to use approximately $40.0 million of the net proceeds
of this offering for acquisitions. We are currently engaged in discussions with
respect to several acquisitions. See "Business -- Strategy" and "-- Acquisition
Program." We also expect to use the net proceeds as follows:
 
     - approximately $9.0 million for capital expenditures including completing
       and equipping our data centers; and
 
     - $8.0 million for repayment of a 9% promissory note issued in favor of
       Matthew Wolf in connection with the acquisition of Interliant Texas,
       which will be paid in full on the consummation of this offering.
 
See "Business -- Technology and Network Operations -- Network Operations" and
"-- Facilities."
 
     The balance of the net proceeds of this offering will be used for working
capital and general corporate purposes. Pending use of the net proceeds for the
above purposes, we intend to invest such funds in short-term investment grade
interest-bearing securities. See "Management's Discussion and Analysis of

                                DIVIDEND POLICY
 
     We have never paid or declared any cash dividends on our common stock. We
currently intend to retain any future earnings for our business and, therefore,
do not anticipate paying cash dividends in the foreseeable future. Future
dividends, if any, will depend on, among other things, our results of
operations, capital requirements, restrictions in loan agreements and on such
other factors as our Board of Directors may, in its discretion, consider
relevant.

                                 CAPITALIZATION
 
   
     The following table sets forth at March 31, 1999 (1) our actual
capitalization, (2) capitalization on a pro forma basis to reflect (a) the
amendment of our Restated Certificate of Incorporation to provide for authorized
capital stock of 200,000,000 shares of common stock and 1,000,000 shares of
undesignated preferred stock and (b) the exercise in April 1999 of warrants to
purchase 749,625 shares of common stock for gross proceeds of $5.0 million and
(3) the pro forma capitalization adjusted to reflect (a) the conversion of
2,647,658 shares of Series A Redeemable Convertible Preferred Stock into an
equal number of shares of common stock upon the consummation of this offering
(see "Description of Capital Stock -- The SOFTBANK Investment") and (b) this
offering, assuming an initial public offering price of $10.00 per share and
after deducting the estimated underwriting discounts and commissions and
offering expenses. You should read this table in conjunction with the Selected
Consolidated Financial Data, the Unaudited Pro Forma Consolidated Financial
Statements and Interliant's Consolidated Financial Statements and Notes thereto
included elsewhere in this prospectus.

                                    DILUTION
 
   
     Our pro forma negative net tangible book value as of March 31, 1999 was
$(2.9) million or $(0.09) per share of common stock. The pro forma net tangible
book value per share of common stock is determined by subtracting our total
liabilities from the total book value of our tangible assets and dividing the
difference by the number of shares of common stock deemed to be outstanding on
the date as of which such book value is determined, after giving effect to the
pro forma events listed in the introductory paragraph of "Capitalization." After
giving effect to (a) the conversion of 2,647,658 shares of Series A Redeemable
Convertible Preferred Stock into shares of common stock upon the consummation of
this offering (see "Description of Capital Stock -- The SOFTBANK Investment")
(b) receipt of net proceeds from the sale of the 7,000,000 shares of common
stock in this offering, assuming an initial public offering price of $10.00 per
share and after deducting the estimated underwriting discounts and commissions
and offering expenses, the pro forma net tangible book value of Interliant as of
March 31, 1999 would have been $73.8 million, or $1.78 per share. This
represents an immediate increase in net tangible book value of $1.87 per share
to existing stockholders and an immediate dilution of $8.22 per share to new
investors purchasing shares at the initial public offering price. Dilution is
defined as the reduction in the proportion of income, or earnings per share, to
which each share is entitled due to the issuance of additional shares. The
following table illustrates the per share dilution:

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
           (DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
     The following selected consolidated financial data should be read in
conjunction with Interliant's (formerly Sage Networks, Inc.) Consolidated
Financial Statements and Notes thereto, the Unaudited Pro Forma Consolidated
Financial Statements and "Management's Discussion and Analysis of Financial
Condition and Results of Operations" included elsewhere in this prospectus. The
statement of operations data for the period ended December 31, 1997 and the year
ended December 31, 1998, and the balance sheet data as of December 31, 1997 and
1998, are derived from the consolidated financial statements of Interliant that
have been audited by Ernst & Young LLP, independent auditors, whose report with
respect thereto is included elsewhere in this prospectus. The statement of
operations data for the three months ended March 31, 1998 and 1999 and the
balance sheet data as of March 31, 1999 have been derived from the unaudited
financial statements included in this prospectus. We believe that the unaudited
historical financial statements contain all adjustments needed to present fairly
the information in those statements, and that the adjustments made consist only
of recurring adjustments.
 
   
     The unaudited pro forma statement of operations data for the year ended
December 31, 1998 and for the three months ended March 31, 1999 assumes that the
acquisitions completed in 1998 and 1999 had occurred on January 1, 1998, and
includes the historical consolidated statements of operations of Interliant,
adjusted for the pro forma effects of such acquisitions. The unaudited pro forma
balance sheet data gives effect to the exercise in April 1999 of warrants to
purchase 749,625 shares of common stock for gross proceeds of $5.0 million. See
"Description of Capital Stock -- The SOFTBANK Investment." The unaudited pro
forma as adjusted balance sheet data gives effect to the conversion of 2,647,658
shares of Series A Redeemable Convertible Preferred Stock into shares of common
stock upon consummation of this offering (see "Description of Capital
Stock -- The SOFTBANK Investment") and the sale of 7,000,000 shares of common
stock offered hereby.
    
 
     Results of operations for the period from inception to December 31, 1997
and for the year ended December 31, 1998 and for the three months ended March
31, 1999 are not necessarily indicative of results of operations for future
periods. Interliant's development and expansion activities, including
acquisitions, during the periods shown below may significantly affect the
comparability of this data from one period to another. The unaudited pro forma
statement of operations data is not necessarily indicative of the results of
operations that would actually have occurred if the transactions had been
consummated as of January 1, 1998 and is not intended to indicate the expected
results for any future period. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

(1) EBITDA represents earnings before net interest expense, income taxes,
    depreciation and amortization and other income (expense). EBITDA is
    presented because it is a widely accepted financial indicator used by
    certain investors and analysts to analyze and compare companies on the basis
    of operating performance and because our management believes that EBITDA is
    an additional meaningful measure of performance and liquidity. EBITDA is not
    intended to present cash flows for the period, nor has it been presented as
    an alternative to operating income (loss) as an indicator of operating
    performance and should not be considered in isolation or as a substitute for
    measures of performance prepared in accordance with generally accepted
    accounting principles. The items excluded from the calculation of EBITDA are
    significant components in understanding and assessing our financial
    performance. Our computation of EBITDA may not be comparable to the
    computation of similarly titled measures of other companies. EBITDA does not
    represent funds available for discretionary uses. See Interliant's (formerly
    Sage Networks, Inc.) Consolidated Financial Statements and Notes thereto

and the Notes thereto and the Unaudited Pro Forma Consolidated Financial
Statements included elsewhere in this prospectus. This discussion contains
forward-looking statements based upon current expectations that involve risks
and uncertainties. Any statements contained herein that are not statements of
historical fact may be deemed to be forward-looking statements. Our actual
results and the timing of certain events may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such a discrepancy include, but are not limited to, those discussed in "Risk
Factors," "Business" and elsewhere in this prospectus.
 
OVERVIEW
 
   
     We are a provider of a wide range of hosting and enhanced Internet services
that enable our customers to deploy and manage their Web sites and network-based
applications more effectively than internally developed solutions. Our Web
hosting services provide virtual, dedicated and co-located hosting solutions to
meet the needs of businesses of all sizes, as their Web sites develop from
low-end marketing brochures to more complex, interactive Web sites and finally
to Web sites that are integral to the operating, marketing and sales and
customer support functions, or mission-critical, of a business. Our application
hosting services consist of groupware hosting and application outsourcing
solutions that can provide our customers with 24x7 remote access to
mission-critical applications and data required by their businesses.
    
 
   
     During 1998 and 1999, our strategy has been to rapidly acquire operating
companies in the Web hosting and application hosting services businesses, to
build or acquire data centers, and to integrate the acquired operations into
those data centers. We acquired 17 operating businesses during 1998 and 1999 for
total consideration of approximately $85.2 million, including transaction costs.
We have accounted for all acquisitions using the purchase method of accounting
which has resulted in the inclusion of substantial intangible assets on our
balance sheet. Of the total consideration, we paid $7.9 million of assumed
seller debt and have or will allocate approximately $(9.7) million to tangible
net assets and $87.0 million to intangible assets which are comprised of
covenants not to compete, customer lists, assembled work force, trade names and
goodwill. In connection with acquisitions where specific intangible assets were
not stated in the purchase agreements, an allocation methodology was applied to
each acquisition to determine the value to be assigned to each type of
intangible asset where appropriate. Amounts not allocated to specific intangible
assets have been recorded as goodwill. Recoverability of our investment in
intangible assets is dependent on our ability to operate our business
successfully and generate positive cash flows from operations. Annual charges to
operations for amortization of intangible assets will be approximately $15.4
million, which will result in increased losses or reduced net income. During
1998, we charged approximately $1.4 million of amortization of the intangible
assets to operations. Additionally, during 1998 we issued stock valued at
approximately $2.6 million as compensation in connection with agreements entered
into with sellers of acquired operating businesses. During 1998, we amortized
and charged to operations approximately $0.8 million of deferred compensation.
The purchase consideration for the acquisitions was in the form of cash, stock
or a combination of cash and stock. See "Business -- Acquisition Program."
    
 
     Most of the operating businesses we acquired in 1998 have been small and
entrepreneurial in nature and highly dependent on the focus and attention of the
owners. It has been our experience that during the negotiation period prior to
an acquisition, the attention of the owners has been diverted from the operation
of the business. The result of this has often been a modest revenue decline
immediately following the closing of the acquisition. In most cases, the owner
continued to have direct responsibility for the acquired business, but in some
instances, we re-assigned the owner to take advantage of unique skill sets that
have broad application within our operations. In those cases, the operating
businesses have experienced a modest decline in revenues due to loss of
customers. These factors resulted in minimal aggregate internal growth in 1998
for us and the businesses we acquired.
 
                                       23
<PAGE>   29
 
     Since our inception in December 1997, we have experienced operating losses
and negative cash flows from operating activities for each quarterly and annual
period. As of December 31, 1998, we had an accumulated deficit of approximately
$9.9 million. Had the companies acquired to date been included since January 1,
1998, our accumulated deficit would have been $29.5 million. The revenue and
income potential of our business is unproven and its limited operating history
makes an evaluation of us and our prospects difficult. We anticipate increased
operating expenses as we:
 
     - expand our sales and marketing initiatives to continue to grow our
       brands;
 
     - fund greater levels of product development;
 
     - continue to build-out our data centers;
 
     - implement centralized billing, accounting and customer service systems;
       and
 
     - continue our acquisition program.
 
Although we have experienced revenue growth, primarily attributable to
acquisitions, we do not believe that this growth is necessarily indicative of
future operating results. Future acquisitions are expected to increase operating
expenses and operating losses and as a result, we expect to incur operating
losses for the foreseeable future. We cannot assure you that we will ever
achieve profitability on a quarterly or annual basis, or, if achieved, that we
will sustain profitability. See "Risk Factors -- We have a history of
significant losses and these losses may increase in the future."
 
RESULTS OF OPERATIONS
 
     We derive our revenues from Web hosting, enhanced Internet services and
consulting services. In March 1999, we acquired Interliant Texas to enter the
application hosting market. Revenues for our Web hosting business consist
primarily of hosting fees and setup fees, which cover costs incurred by us to
establish a customer's Web site. We provide virtual, dedicated and co-located
hosting. We charge our Web hosting customers a fixed amount for bandwidth
availability and incremental fees if those fixed amounts are exceeded. In
addition, our virtual Web hosting customers are also charged for disk space on a
server, dedicated hosting customers are charged for use of one or more dedicated
servers and our co-located customers are charged for the amount of physical
space such co-located customers' servers occupy. We charge flat rates for our
enhanced Internet services. For application hosting, our revenues are comprised
primarily of a one-time implementation fee and monthly usage fees per number of
end users, including bandwidth fees. For our consulting services, we charge
either a fixed fee or a fee based on time and materials.
 
     Our contracts with our Web hosting customers typically range in length from
month-to-month to one year, a large proportion of which are cancellable by
either us or our customers with 30 days notice. Our contracts with our
application hosting customers typically range in length from one year to three
years. Revenues derived from hosting are recognized ratably over the applicable
contractual period. Payments received and billings in advance of providing
services are deferred until such services are provided. Revenues from consulting
services are recognized as the services are rendered. Substantially all of our
consulting contracts call for billings on a time and materials basis.
 
     Cost of revenues consists primarily of salaries and related expenses
associated with consulting and network operations personnel as well as data
communications expenses, including one-time fees for circuit installation and
variable recurring circuit payments to network providers. Monthly circuit
charges vary based upon circuit type, distance and usage, as well as the term of
the contract with the carrier.
 
     Sales and marketing expense consists of personnel costs associated with the
direct sales force, the internal telesales group and product marketing
employees, as well as costs associated with marketing programs, product
literature, external telemarketing costs and corporate marketing activities,
including public relations.
 
                                       24
<PAGE>   30
 
     Start-up and acquisition integration costs consist primarily of salaries
for our acquisition and integration team as well as related travel expenses.
 
     General and administrative expense includes the cost of customer service
functions including:
 
     - finance;
 
     - accounting;
 
     - human resources;
 
     - legal and executive salaries; and
 
     - fees paid for professional services and corporate overhead.
 
THREE MONTHS ENDED MARCH 31, 1999 AND 1998
 
  Revenues
 
     Revenues were $5.4 million for the three months ended March 31, 1999
representing an increase of $5.4 million from the comparable 1998 period. The
increase in revenues was due primarily to the 15 acquisitions consummated during
the last three quarters of 1998 and the first quarter of 1999.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
revenues for the quarter ended March 31, 1999 were $10.3 million. Interliant
Texas accounted for 44.8% of such revenues. Revenues for Interliant Texas were
$4.6 million for the quarter ended March 31, 1999 compared to $4.8 million for
the quarter ended March 31, 1998. This decrease was due to lower bandwidth
charges to our customers in 1999.
 
   
     For the three months ended March 31, 1999, on a pro forma basis and giving
effect to acquisitions completed to date:
    
 
   
     - Web hosting revenues comprised 31.4% of our revenues;
    
 
   
     - application hosting revenues comprised 44.8% of our revenues;
    
 
   
     - consulting services revenues comprised 16.0% of our revenues; and
    
 
   
     - each of disk space, excess bandwidth and one-time implementation fee
       revenues have been de minimus.
    
 
  Cost of Revenues
 
     Cost of revenues increased by $3.2 million for the three months ended March
31, 1999. This increase was attributable to the 15 acquisitions consummated
during the last three quarters of 1998 and the first quarter of 1999. In the
future, cost of revenues may fluctuate due to capacity utilization, the timing
of investments in data centers, changes in the mix of services, fluctuations in
bandwidth costs and increased levels of staffing.
 
     On a pro forma basis, giving effect to acquisitions completed to date, cost
of revenues for the quarter ended March 31, 1999 were $6.0 million. Interliant
Texas accounted for 46.7% of such costs of revenues. Cost of revenues for
Interliant Texas were $2.8 million for the quarter ended March 31, 1999,
approximately the same as the amount for the quarter ended March 31, 1998.
 
  Sales and Marketing
 
     Sales and marketing expense increased by $1.8 million for the three months
ended March 31, 1999. This increase was attributable to the 15 acquisitions
consummated during the last three quarters of 1998 and the first quarter of
1999. A key component of our strategy is to significantly increase our sales and
marketing activities for application hosting and Web hosting products. This will
include the expansion of our sales force, development of reseller and referral
partner channels and increased marketing efforts to
 
                                       25
<PAGE>   31
 
grow recognition of our brands. As a result, sales and marketing expenses will
increase substantially in future periods. We expect sales and marketing expenses
for the year ending December 31, 1999 to exceed $20.0 million.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
sales and marketing expense for the three months ended March 31, 1999 was $3.5
million. Interliant Texas accounted for 53.2% of such sales and marketing
expense. Sales and marketing expense for Interliant Texas were $1.9 million for
the three months ended March 31, 1999 compared to $1.5 million for the three
months ended March 31, 1998. This increase was attributable to increased
personnel in the sales force and the marketing staff.
 
  General and Administrative
 
     General and administrative expense increased by $3.4 million for the three
months ended March 31, 1999. This increase in general and administrative expense
was attributable to the 15 acquisitions consummated during the last three
quarters of 1998 and the first quarter of 1999 and increased investments in
infrastructure and levels of staffing to implement centralized billing,
accounting and customer service systems to integrate the operations of acquired
companies. Substantial staffing increases are expected to continue in future
periods.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
general and administrative expense for the three months ended March 31, 1999 was
$5.6 million. Interliant Texas accounted for 28% of such general and
administrative expense. General and administrative expense of Interliant Texas
was $1.6 million for the three months ended March 31, 1999 compared to $1.3
million for the three months ended March 31, 1998. This increase was
attributable to higher professional fees and training expenses.
 
  Depreciation
 
     Depreciation expense increased by $0.7 million for the three months ended
March 31, 1999. This increase in depreciation expense was attributable to the 15
acquisitions consummated during the last three quarters of 1998 and the first
quarter of 1999 and investment in plant and equipment by us to complete our data
center in Atlanta. We expect depreciation expense to increase in the future as
we continue to invest in data centers and systems to integrate future
acquisitions and support future growth.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
depreciation expense for the three month period ended March 31, 1999 was $1.3
million. Interliant Texas accounted for 53.8% of such depreciation expense.
Depreciation expense of Interliant Texas was $0.7 million compared to $0.5
million for the three month period ended March 31, 1998. This increase was due
to an increase in investment in computer hardware, primarily servers.
 
  Amortization
 
     Amortization expense increased by $2.1 million for the three months ended
March 31, 1999. This increase in amortization expense was attributable to the 15
acquisitions consummated during the last three quarters of 1998 and the first
quarter of 1999. We expect amortization expense to increase in future periods as
we continue to make additional acquisitions as well as reflect amortization of
intangibles associated with acquisitions consummated to date.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
amortization expense for the three month period ended March 31, 1999 was $4.2
million. Amortization expense related to the acquisition of Interliant Texas
represented 42.8% of such amortization expense.
 
  Start-up and Acquisition Integration Costs
 
     Start-up and acquisition integration costs increased by $0.9 million for
the three months ended March 31, 1999. This increase was attributable to our
continuing acquisition program and our expanded acquisition integration team,
including salaries and travel expenses, and the amortization of deferred stock
compensation costs.

YEAR ENDED DECEMBER 31, 1998 AND 1997
 
  Revenues
 
     Our revenues increased by $4.9 million for the year ended December 31,
1998. This increase in revenues was primarily attributable to the 12
acquisitions consummated during 1998.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
revenues for the year ended December 31, 1998 were $41.3 million. Interliant
Texas accounted for 51% of such revenues. Revenues for Interliant Texas were
$21.2 million for the year ended December 31, 1998 compared to $16.9 million for
the year ended December 31, 1997. This increase was primarily due to an increase
in the number of higher revenue generating customers.
 
   
     For the year ended December 31, 1998, on a pro forma basis and giving
effect to acquisitions completed to date:
    
 
   
     - Web hosting revenues comprised 28.0% of our revenues;
    
 
   
     - application hosting revenues comprised 51.3% of our revenues;
    
 
   
     - consulting services revenues comprised 14.0% of our revenues; and
    
 
   
     - each of disk space, excess bandwidth and one-time implementation fee
       revenues have been de minimus.
    
 
  Cost of Revenues
 
     Cost of revenues increased by $3.2 million for the year ended December 31,
1998. This increase in cost of revenues was attributable to the 12 acquisitions
consummated during 1998. In the future, cost of revenues may fluctuate due to
capacity utilization, the timing of investments in data centers, changes in the
mix of services, fluctuations in bandwidth costs and increased levels of
staffing.
 
     On a pro forma basis, giving effect to acquisitions completed to date, cost
of revenues for the year ended December 31, 1998 were $20.3 million. Interliant
Texas accounted for 58.5% of such cost of revenues. Cost of revenues for
Interliant Texas were $11.9 million for the year ended December 31, 1998
compared to $9.4 million for the year ended December 31, 1997. This increase was
primarily due to an increase in staffing, a change in mix of staff to higher
paid employees, including technical engineers, and increased connectivity costs
associated with network upgrades.
 
  Sales and Marketing
 
     Sales and marketing expense increased by $2.6 million for the year ended
December 31, 1998. This increase in sales and marketing expense was attributable
to the 12 acquisitions consummated during 1998. A key component of our strategy
is to significantly increase our sales and marketing activities for application
hosting and Web hosting products. See "Business -- Strategy" and "-- Marketing."
This will include the expansion of our sales force, development of reseller and
referral partner channels and increased marketing efforts to grow recognition of
our brands. As a result, sales and marketing expenses will increase
substantially in future periods.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
sales and marketing expense for the year ended December 31, 1998 was $9.4
million. Interliant Texas accounted for 71.6% of such sales and marketing
expense. Sales and marketing expense for Interliant Texas were $6.7 million for
the year ended December 31, 1998 compared to $4.4 million for the year ended
December 31, 1997. This increase was primarily due to an increase in staffing, a
change in mix of staff to higher paid employees and increased external marketing
costs.
 
                                       27
<PAGE>   33
 
  General and Administrative
 
     General and administrative expense increased to $5.1 million for the year
ended December 31, 1998 as compared to $0.2 million for the period from December
8, 1997 (inception) to December 31, 1997. This increase in general and
administrative expense was attributable to the 12 acquisitions consummated
during 1998 and increased investments in infrastructure and levels of staffing
to implement centralized billing, accounting and customer service systems to
integrate the operations of acquired companies. Staffing for general and
administrative functions increased substantially late in 1998 and is expected to
continue to increase during 1999 and as a result, general and administrative
expense will increase substantially in future periods.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
general and administrative expense for the year ended December 31, 1998 was
$20.6 million. Interliant Texas accounted for 20.1% of such general and
administrative expense. General and administrative expense of Interliant Texas
was $4.1 million for the year ended December 31, 1998 compared to $2.9 million
for the year ended December 31, 1997. This increase was primarily due to an
increase in staffing, a change in mix of staff to higher paid employees,
increased training costs and increased telecommunications costs.
 
  Depreciation
 
     Depreciation expense increased by approximately $0.7 million for 1998. This
increase was due to the acquisition of approximately $5.7 million of furniture,
fixtures and equipment. This amount includes approximately $1.4 million acquired
with operating businesses we acquired during 1998. Investments included the
build-out and acquisition of equipment for our Web hosting facilities to ensure
high levels of service to our customers and capacity for future growth and of
technology and infrastructure to implement centralized billing, accounting and
customer service systems to integrate the operations of acquired companies. We
expect depreciation expense to increase in the future as we continue to invest
in data centers and systems to integrate future acquisitions and support future
growth.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
depreciation expense for the year ended December 31, 1998 was $3.8 million.
Interliant Texas accounted for 66.1% of such depreciation expense. Depreciation
expense of Interliant Texas was $2.5 million for the year ended December 31,
1998 compared to $1.6 million for the year ended December 31, 1997. This
increase was due to an increase in investment in computer hardware, primarily
servers.
 
  Amortization
 
     Amortization expense increased by approximately $1.4 million in 1998. The
amortization expense was attributable to intangible assets associated with the
12 acquisitions consummated during 1998. On a pro forma basis, giving effect to
acquisitions completed to date, amortization expense for the year ended December
31, 1998 was $14.5 million. Amortization expenses related to the acquisition of
Interliant Texas represented $7.4 million of such amortization expense. We
expect amortization expense to increase in the future as we continue to acquire
businesses.
 
  Start-up and Acquisition Integration Costs
 
     Start-up and acquisition integration costs increased by $1.7 million for
the year ended December 31, 1998. This increase was primarily attributable to
the 12 acquisitions consummated during 1998. We expect start-up and acquisition
integration costs to remain relatively constant in future periods.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     We have historically financed our operations and acquisitions primarily
from private placements of equity. Net cash used in operations for the three
months ended March 31, 1999 was $4.2 million. This reflects primarily the net
loss for the period of $7.2 million along with changes in operating assets and
liabilities. Net cash used for investing activities for the three month period
ended March 31, 1999 was
 
                                       28
<PAGE>   34
 
$21.8 million, of which $1.0 million was for purchases of furniture, fixtures
and equipment, and $18.9 was for acquisitions of businesses. Net cash from
financing activities for the three month period ended March 31, 1999 was $23.6
million, reflecting $24.0 million of proceeds from issuance of common stock and
preferred stock less issuance costs and repayment of debt under equipment
financing facilities.
 
     We had $4.4 million in cash and cash equivalents at March 31, 1999. In
April 1999 the Company received $5.0 million for the issuance of common stock
upon the exercise of a warrant by SOFTBANK.
 
     In connection with our acquisition of Interliant Texas, we assumed a
promissory note in favor of Mathew Wolf in the amount of $8.0 million and a
promissory note in favor of Erving Wolf in the amount of $7.9 million. Upon the
closing of this acquisition, we paid in full the note in favor of Erving Wolf,
and we canceled the note in favor of Mathew Wolf and replaced it with a note
issued by us for the same principal amount (the "Wolf Note") which bears
interest at a rate of 9% per annum and is payable in full upon the completion of
this offering.
 
     In addition to funding ongoing operations and capital expenditures
including, without limitation, $4.0 million of expenditures planned to be made
in connection with the application hosting business, our principal commitments
consist of non-cancelable operating leases and contingent payments of earnouts
to certain sellers of operating companies acquired by us. If all earnout targets
are achieved in full, total payments pursuant to all earnouts will be $1.8
million in cash and 37,481 shares of common stock in 1999 and $1.3 million in
cash and 37,481 shares of common stock in 2000.
 
   
     During 1998, we constructed a data center in Atlanta into which the
majority of the operating businesses we acquired have been or are being
integrated. We believe that this facility has the capacity to service a larger
number of customers than are currently serviced there. The cost of constructing
and equipping this facility was approximately $2.0 million. We intend to invest
approximately $5.0 million to construct and equip our data centers as more
operating businesses are acquired and integrated into these facilities, and as
sales and marketing efforts generate internal growth, requiring additional
servers, routers and related equipment. We may decide to construct one or more
additional facilities in 1999, dependent upon acquisition activity. Our current
anticipated level of capital expenditures for 1999 is expected to be
approximately $15.0 million, but may vary from that amount depending upon
acquisitions and changes in operating plans. We are in the process of
negotiating a sale/leaseback transaction in the amount of approximately $6.0
million. Pursuant to the proposed transaction, we would sell and then lease back
some of our capital equipment, including computer, telecommunications and other
general office equipment in our data center in Atlanta.
    
 
     At March 31, 1999, restricted cash totaled $1.4 million. In connection with
our acquisition of Interliant Texas, we entered into an Assignment and
Assumption Agreement, dated March 10, 1999, pursuant to which we were assigned
all right, title and interest in and to, and assumed all obligations under, the
lease for the Houston data center. In connection with receiving the landlord's
consent to assignment of the lease, we were required to issue letters of credit
in favor of the landlord totaling approximately $0.7 million to replace the
letters of credit issued by Interliant Texas. The aggregate dollar amount which
may be drawn upon by the landlord under these letters of credit shall be reduced
at specified dates in specified amounts such that by August 8, 2000 all of the
letters of credit shall have lapsed. In addition, restricted cash includes
approximately $0.5 million held in escrow in connection with one of our
acquisitions and approximately $0.2 million held to secure outstanding letters
of credit used as deposits on our facilities.
 
     We believe that our existing cash and cash equivalents together with the
net proceeds of this offering will be adequate to meet operating needs through
the end of 1999 and will provide enough funds to continue our acquisition
program through 1999. Thereafter, we expect to require additional financing. If
our plans or assumptions change or prove to be inaccurate, we may be required to
seek additional sources of capital or seek additional capital sooner than
currently anticipated. We may also seek to raise additional capital to take
advantage of favorable conditions in the capital markets. We have no credit
facility or other working capital credit line under which it may borrow funds
for working capital or other general corporate purposes.

YEAR 2000 COMPLIANCE
 
     Currently, many computer and software products are coded to accept
two-digit entries in the date code field. These date code fields will need to
accept four-digit entries to distinguish 21st century dates from 20th century
dates. As a result, many companies' software and computer systems, including our
own, may need to be upgraded or replaced in order to comply with Year 2000
requirements. We recognize the need to ensure that our operations will not be
adversely impacted by Year 2000 software and computer system failures.
 
     State of Readiness.  We have made a preliminary assessment of the Year 2000
readiness of our information technology, or IT, systems, including the hardware
and software that enable us to provide and deliver our solutions, and our non-IT
systems. Our plan consists of:
 
     - quality assurance testing of our internally developed proprietary
       software and systems;
 
     - contacting third-party suppliers, vendors and licensors of material
       hardware, software and services that are both directly and indirectly
       related to the delivery of our solutions to our customers;
 
     - contacting vendors of material non-IT systems;
 
     - assessment of repair or replacement requirements;
 
     - repair or replacement;
 
     - implementation; and
 
     - creation of contingency plans in the event of Year 2000 failures.
 
     We have been informed by our vendors of material hardware and software
components of our IT systems that their products used by us are currently Year
2000 compliant. We are currently assessing the materiality of our non-IT systems
and will seek assurances of Year 2000 compliance from providers of material
non-IT systems. Until such testing is complete and such vendors and providers
are contacted, we will not be able to completely evaluate whether our IT systems
or non-IT systems will need to be revised or replaced. We plan to complete our
Year 2000 evaluation during the second half of 1999.
 
     Costs.  To date, we have not incurred any material expenditures in
connection with identifying or evaluating Year 2000 compliance issues. Most of
our expenses have related to our internal staffing costs associated with the
evaluation process and Year 2000 compliance matters generally. This trend is
expected to continue in the future. At this time, we do not possess the
information necessary to estimate the potential costs of revisions to our
software and systems should such revisions be required or the replacement of
third party software, hardware or services that are determined not to be Year
2000 compliant. Although we do not anticipate that such expenses will be
material, such expenses, if higher than anticipated, could have an adverse
effect on our business.
 
     Risks.  We are not currently aware of any Year 2000 compliance problems
relating to our IT or non-IT systems that would have a material adverse effect
on our business, results of operations and financial condition. We cannot give
you any assurance that we will not discover Year 2000 compliance problems in our
software and systems that will require substantial revisions. In addition, we
cannot give you any assurance that third party software, hardware or services
incorporated into our material IT and non-IT systems will not need to be revised
or replaced, all of which could be time consuming and expensive. Our failure to
fix or replace our software, hardware or services on a timely basis could result
in lost revenues, increased operating costs and the loss of customers and other
business interruptions, any of which could have an adverse effect on our
business. Moreover, the failure to adequately address Year 2000 compliance
issues in our IT and non-IT systems could result in claims of mismanagement,
misrepresentation or breach of contract and related litigation, which could be
costly and time-consuming to defend. In addition, we cannot give you any
assurance that governmental agencies, utility companies, telecommunication
companies, other Internet service providers, third party service providers,
hardware and software manufacturers and others outside our control will be Year
2000 compliant. The failure by such entities to be Year 2000 compliant could
result in a systemic failure beyond our control, such as a prolonged
                                       30
<PAGE>   36
 
Internet, telecommunications or electrical failure, which could also prevent us
from delivering our services to our customers, decrease the use of the Internet
or prevent users from accessing the Web sites of our customers. Any of these
occurrences could have an adverse effect on our business.
 
     Contingency Plan.  As discussed above, we are engaged in an ongoing Year
2000 assessment and have not yet developed any contingency plans. The responses
received from third-party vendors and service providers will be taken into
account in determining the nature and extent of any contingency plans.
 
   
INTEREST RATE RISK
    
 
   
     We have limited exposure to financial market risks, including changes in
interest rates. At March 31, 1999, we had short-term investments of
approximately $2.1 million. These short-term investments consist of highly
liquid investments in debt obligations of highly rated entities with maturities
of between one and 90 days. These investments are subject to interest rate risk
and will fall in value if market interest rates increase. We expect to hold
these investments until maturity, and therefore expect to realize the full value
of these investments, even though changes in interest rates may affect their
value prior to maturity. If interest rates decline over time, this will result
in a reduction of our interest as our cash is reinvested at lower rates.

                                    BUSINESS
 
OUR COMPANY
 
   
     We are a provider of a wide range of hosting and enhanced Internet services
that enable our customers to deploy and manage their Web sites and network-based
applications more effectively than internally developed solutions. Hosting
services we provide include:
    
 
     - Virtual hosting, or shared server hosting, which allows customers to
       store their databases, applications or Web sites on a shared server which
       is owned and maintained by us;
 
     - Dedicated hosting, which allows customers to store their databases,
       applications or Web sites on a server typically owned and maintained by
       us that is dedicated solely to that customer;
 
     - Co-located hosting, which allows customers to store their databases,
       applications or Web sites on servers that they own but which are
       maintained by us and are located in our data centers;
 
     - Groupware hosting, which allows customers to store groupware applications
       such as email, discussion forums and document libraries on computers
       which we own and manage in our data centers; and
 
     - Application outsourcing, which combines hosting services with prepackaged
       applications that can be sold directly to our customers. By doing so, our
       customers can quickly deploy a software application solution without
       having to purchase hardware, software or network connections.
 
   
     Since our inception in December 1997, we have grown rapidly through the
acquisition of 17 hosting and related Internet service businesses. We provide
Web hosting solutions to more than 47,000 customers, representing more than
79,000 active domains. We also host more than 10,000 customized Lotus Notes/
Domino based applications for more than 1,300 customers and believe that we are
the leading provider of Lotus Notes/Domino hosting solutions. We have two
state-of-the-art primary data centers in Atlanta and Houston and a recently
leased facility in the Tysons Corner, Virginia. Our Atlanta and Houston data
centers are monitored on a 24x7 basis and include sophisticated monitoring and
diagnosis, 24x7 customer support, redundant and high-speed network connectivity
and uninterruptible power supply.
    
 
INDUSTRY BACKGROUND
 
     Growth of the Internet.  The Internet is experiencing significant growth
and is emerging as a global medium for communications and commerce.
International Data Corporation or IDC estimates that the number of Web users
worldwide will increase from approximately 97.3 million at the end of 1998 to
319.8 million by the end of 2002, a 34.6% compounded annual growth rate. IDC
also estimates that the number of Web users in the United States will increase
from approximately 51.6 million at the end of 1998 to 135.9 million by the end
of 2002, a 27.4% compounded annual growth rate. During this same period, the
number of business Web sites in the United States is projected by Forrester
Research, Inc. to increase from approximately 650,000 in 1998 to approximately
2.6 million in 2002, a 41.1% compounded annual growth rate. This growth in the
number of Web users and number of Web sites is being driven by a number of
factors including:
 
     - the large and growing installed base of personal computers;
 
     - easier and less expensive alternatives for Internet access;
 
     - improvements in the speed, reliability and security of the Internet;
 
     - commerce-enabling technologies;
 
     - higher quality and more diverse content;
 
     - an increase in the number of networked applications; and
 
                                       32
<PAGE>   38
 
     - the proliferation of broadband technologies that promise consumers
       faster, more convenient access to the Internet.
 
     Growth in Business Use of the Internet.  The dramatic growth in usage
combined with enhanced functionality and accessibility have made the Internet an
increasingly attractive medium for businesses to:
 
     - disseminate information;
 
     - engage in e-commerce;
 
     - build customer relationships;
 
     - streamline and automate data-intensive processes; and
 
   
     - communicate more efficiently with dispersed employees.
    
 
     In the last several years, businesses have emerged with operating models
that are exclusively dependent on the Internet, while traditional businesses of
all sizes are working quickly to establish a Web presence. Many of these
businesses establish their initial online presence with a simple, static
brochure for marketing purposes. As they become more familiar with the Internet
as a communications platform, an increasing number of businesses are
implementing more complex, mission-critical applications on the Web including
sales, customer service, customer acquisition and retention, employee
communications and e-commerce between suppliers and business partners.
 
     Trend Toward Outsourcing.  According to Forrester Research, Inc., U.S.
firms are now spending approximately 25% of their overall IT budgets on
outsourcing services. These services include packaged application software
implementation and support, customer support and network development and
maintenance. Reasons for the growth in outsourcing include:
 
     - the desire of companies to focus on their core businesses;
 
     - the increased costs that businesses experience in developing and
       maintaining their networks and software applications;
 
     - the fast pace of technological change that shortens time to obsolescence
       and increases capital expenditures as companies attempt to capitalize on
       leading-edge technologies;
 
     - the challenges faced by companies in hiring, motivating and retaining
       qualified application engineers and IT employees; and
 
     - the desire of companies to reduce deployment time and risk.
 
     Trend Toward Web Hosting Outsourcing.  Many businesses, both small and
large, lack the resources and expertise to cost-effectively develop and
continually enhance their Web sites with evolving technologies while maintaining
a network infrastructure that remains operational in the event of a hardware or
software failure as well as supports increased bandwidth capability as their
business grows. Small- to medium-sized businesses typically lack the IT
resources, capital and scale to design their own Web sites and install, maintain
and monitor their own Web servers and Internet connectivity. Large businesses
typically require state-of-the-art facilities and networks that are monitored
and managed on a 24x7 basis by experts in Internet technology and that can be
upgraded and scaled to meet the needs of mission-critical Internet applications
that may be integral to their businesses. As a result, we believe enterprises of
all sizes are seeking outsourcing arrangements to help:
 
     - build effective Web sites;
 
     - improve their sites' reliability and performance;
 
     - provide continuous monitoring of their Internet operations; and
 
     - reduce costs.
 
                                       33
<PAGE>   39
 
     Trend Toward Application Hosting Outsourcing.  Businesses increasingly face
competitive demands to automate business processes. This problem has been
exacerbated by a shortage of IT professionals. Until recently, implementation of
Internet applications required development of in-house software applications or
the customization of existing packages. This made each implementation unique and
costly. It also made implementation time frames and costs unpredictable. We
believe that businesses of all sizes have a significant need to outsource the
hosting of these and other software applications to improve core business
processes, reduce costs and enhance their global competitive position.
 
OUR OPPORTUNITY
 
     Today the hosting market is fragmented, consisting for the most part of:
 
     - small local and regional providers who do not have the capital, resources
       or capabilities to provide quality services at competitive prices;
 
     - large national providers who focus on Internet connectivity rather than
       on hosting; and
 
     - consulting and Web design firms for which hosting is not their core
       competency.
 
     We believe that a significant market opportunity exists for a
nationally-recognized hosting solutions provider with the scale and expertise to
offer a wide range of value-priced services to businesses of all sizes.
Interliant believes that through the acquisition and consolidation of hosting
and enhanced Internet service businesses, a hosting provider can offer a full
range of services that enable businesses to deploy, use, expand and update their
Web sites and applications infrastructures more rapidly and cost-effectively
than internally developed solutions.
 
     Web Hosting Opportunity.  IDC estimates that the worldwide market for Web
hosting services will grow from $696 million in 1998 to $10.7 billion by 2002, a
98.0% compounded annual growth rate. The market for Web hosting services can be
segmented into virtual, dedicated and co-located hosting. Virtual hosting
primarily addresses the needs of small- to medium-sized businesses and includes
such services as disk space, shared connectivity and certain value-added
services such as e-mail hosting, e-commerce tools and other specialized
offerings. Dedicated and co-located hosting services primarily address the needs
of medium- to large-sized businesses and include:
 
     - dedicated server equipment owned by either the hosting provider or the
       customer, with an emphasis on network reliability;
 
     - 24x7 monitoring;
 
     - dedicated and redundant bandwidth;
 
     - flexibility to scale rapidly; and
 
     - high-end, value-added services such as consulting services, systems
       integration and links to legacy systems.
 
     We believe we are well positioned to take advantage of the opportunities
which exist for a nationally-recognized Web hosting solutions provider with the
scale and expertise to offer a wide range of value-priced services to businesses
of all sizes.
 
     Application Hosting Opportunity.  Forrester Research, Inc. reports that the
worldwide market for outsourcing application software products will grow from
approximately $1.0 billion in 1997 to over $21.0 billion by 2001, a 111.1%
compounded annual growth rate. Traditionally, enterprises faced with the issues
of internal development and maintenance of application hosting capabilities have
sought solutions from a variety of information technology providers including
system integrators, Internet service providers, hardware and software vendors
and telecommunication companies. Thus, these companies have had to work with at
least three independent suppliers: a software applications provider, a systems
integrator and a site hosting provider, or have had to support implementation
with in-house resources. There are inherent conflicts and difficulties with this
approach, as each supplier is dedicated to providing its own specific
 
                                       34
<PAGE>   40
 
product or service with only limited knowledge of the bundle of products and
services required to provide the complete business solution. We believe that
these trends create a substantial market opportunity for a single-source
solution that combines software from multiple vendors, hardware, systems
integration and Internet-based communications in an integrated service offering.
Interliant believes it is well-positioned to take advantage of these
opportunities as companies realize the value a single-source hosting service
provider can offer in facilitating deployment and improving management of their
corporate intranet and extranet solutions as well as mission-critical
applications.
 
OUR SOLUTION
 
     We are a provider of hosting solutions that enable our customers to deploy
and manage their Web sites and network-based applications more effectively than
internally developed solutions and to take advantage of a single-source solution
for their Internet-enabled application software needs. We offer a unique blend
of technological expertise, partnering ability and understanding of the business
and licensing models which it believes are essential to succeed in the hosting
marketplace. We believe we have developed the infrastructure, resources,
application management expertise and industry relationships required to
capitalize on this emerging market opportunity.
 
     We provide the following advantages to our customers:
 
     Comprehensive Hosting Solutions.  We are able to provide Web hosting
services that meet our customers' needs as their Web sites evolve from low-end
marketing brochures to more complex, interactive Web sites and finally to
applications that are integral to their businesses. In addition, our application
hosting services such as groupware hosting and application outsourcing can
provide our customers with continuously available remote access to applications
and data which are mission-critical. Finally, we offer consulting services and a
broad range of enhanced Internet services such as e-commerce capabilities,
multimedia hosting and community hosting.
 
     Performance and Reliability.  Our hosting solutions help to ensure that our
customers' Web sites and networking applications are continuously online and
deliver data rapidly to users. Our state-of-the-art data centers in Atlanta and
Houston provide high-quality performance and reliability through features such
as a redundant, high-speed, secure network architecture, continuous monitoring,
alternate power sources, environmental controls, regular data back-ups and a
fault tolerant hosting platform. Interliant's Network Operations Centers or NOCs
monitor Interliant's network on a 24x7 basis and allow its staff to minimize
service interruptions.
 
     Cost Savings.  Our customers benefit from our focus on hosting and the
capital and labor investments that we have made to support hosting and enhanced
Internet services. For customers to replicate our performance and reliability
would require them to make significant expenditures for equipment, personnel and
dedicated bandwidth. We believe that our hosting solutions are significantly
more cost-effective and reliable than in-house solutions, both for businesses
with low-end application requirements as well as for those businesses whose
Internet operations are mission-critical and require sophisticated application
support.
 
     Customer Service.  We are dedicated to providing the highest quality
customer service. We endeavor to provide rapid and accurate responses through
customer service personnel who can answer questions over the telephone or via
e-mail. In addition, Interliant's customer service organizations in Atlanta and
Houston can address technical problems on a 24x7 basis. Interliant has invested
in advanced customer service software and call routing technology to streamline
the customer service process. Interliant also offers customers who are hosted in
its Atlanta data center a self-service customer support alternative which
provides online access to account and billing data and site statistics such as
disk storage capacity and bandwidth utilization.

STRATEGY
 
     Our objective is to become the industry benchmark in the hosting services
market by providing businesses with cost-effective, innovative solutions that
will allow them to capitalize on the potential of the Internet. To achieve this
objective, our strategy includes the following key elements:
 
     Build the Interliant Brand.  We believe we have established a strong brand
identity within the application hosting industry under the Interliant brand. Our
brand will be enhanced as we begin marketing Web hosting products under the
Interliant brand and will be further enhanced as acquired companies are
assimilated under our brands. We intend to continue to build name recognition
for our brand and strengthen our brand recognition by marketing our full range
of services through an integrated marketing communications program using public
relations, print and online advertising campaigns and other strategic
initiatives as well as cooperative promotions with key hardware and software
vendors.
 
     Continue Acquisition Program.  We intend to continue our acquisition
program to capitalize on consolidation opportunities in the hosting and enhanced
Internet services market in the United States and overseas. We expect that these
acquisitions will also result in substantial operating synergies, greater
internal growth and cost savings. Further, we plan to capitalize on best
practices we may identify within acquired companies to maintain our competitive
advantage and to ensure ongoing delivery of high quality hosting services to our
customers.
 
     Expand Multiple Sales Channels.  We reach our customers through multiple
sales channels including a direct sales force, indirect sales through numerous
resellers and referral partners, inbound and outbound telesales and Web
marketing programs. We intend to continue expanding these channels to further
enhance our ability to attract customers of all sizes. As an example, we
recently launched our business partner program, creating standard incentives
across our entire product line to foster growth of our business partner network.
 
     Leverage the Interliant Customer Base.  We intend to capitalize on the
enhanced revenue potential of the customer bases of our acquired companies,
leveraging the numerous cross-selling opportunities of our expanded line of
branded service offerings. We will use our multiple sales channels, including
our direct sales force, to target specific customer segments within our diverse
customer base with relevant new product offerings to realize increased revenues.
For example, we believe that we can grow our revenues by cross-selling existing
Web hosting customers with application hosting and consulting services. Further,
we believe that by coordinating the sales efforts of our combined Web hosting,
application hosting and consulting sales forces, we can increase customer leads
and referrals. Finally, we intend to assimilate the customer bases of our
acquired companies into a unified customer information management system to
facilitate sophisticated analysis and segmentation of our total customer base
and thus enable us to maximize marketing and sales opportunities.
 
     Develop Strategic Relationships.  We have established and continue to seek
strategic relationships that enhance our infrastructure and distribution
capabilities and broaden our product offerings. We believe that our strategic
alliances with companies such as IBM Corporation, Lotus Development Corporation,
Microsoft Corporation, UUNET Technologies, Inc., Equant, N.V., Allaire
Corporation, Elemental Software, Inc. and iMall, Inc. enable us to provide
complete, scalable and reliable hosting solutions to our customers, resellers
and referral partners.

     - 24x7 customer support through the NOCs and customer service centers;
 
     - remote access management and reporting tools;
 
     - a high-speed network designed to continue operating in the case of any
       software or hardware failure;
 
     - uninterruptible power supply, including back-up generators capable of
       sustaining server operations for more than one week;
 
     - firewall, intrusion monitoring and site security auditing;
 
     - full daily back-ups with off-site storage;
 
     - air-conditioned, static and humidity controlled environment; and
 
     - high level of physical security.
 
It is our intention that all product offerings marketed under our brands and
hosted at data centers other than Atlanta and Houston also have the above
features. Customers generally pay monthly, quarterly or annual fees for the
services used, as well as one-time fees for installation and any equipment
purchased by the customer.
 
   
     On a pro forma basis, giving effect to acquisitions completed to date, Web
hosting revenues comprised 28.0% of our revenues in the year ended December 31,
1998 and 31.4% of our revenues for the three months ended March 31, 1999.
Although we do not account for revenues based on the virtual, dedicated and
co-located components of our Web hosting product offerings, we derive a
substantial majority of our revenues from virtual hosting as 84.0% of active
domains managed by us at March 31, 1999 are virtual hosting domains.

     Virtual Hosting.  Our virtual hosting solution provides customers with all
the elements needed to establish a basic presence on the Web at a reasonable
cost. This entry-level service is known as virtual hosting because the
customer's home page has its own domain name, www.mycompany.com, and appears to
exist as a stand-alone server. It operates with the speed and efficiency of
Interliant's high-speed connections and its location at our facility remains
invisible to Web site visitors. Customers are able to have their own Web site
with a domain name at a fraction of the cost of maintaining it themselves. As a
result, virtual hosting is an economical solution for relatively simple or
moderately accessed Web sites. Because customers do not need to invest in costly
hardware or personnel to accommodate future growth, we believe this solution
also maximizes the customers' flexibility.
 
   
     For these accounts, we host the site on a UNIX or Windows NT server that is
shared by multiple customers. Prices for virtual hosting products marketed under
the Sage Networks and Interliant brands range from $25 to $350 a month,
depending on the data transfer limit, storage capacity, number of e-mail
accounts provided and additional functionality requested such as e-commerce
capabilities, multimedia hosting and community hosting. For certain customers of
acquired businesses, the price range may be lower depending upon the
functionality of the services and reflecting a lower level of services requested
by such customers. In 1998, our average virtual hosting customer paid
approximately $20 per month.
    
 
     Dedicated Hosting.  As companies increase the complexity, level of traffic
or reliance on their Web sites, they may prefer to host their Web site on a
dedicated server, which is typically owned and maintained by us. A dedicated
server provides greater server and network resources to our customers than
virtual hosting and allows them to configure their hardware to optimize site
performance. Customers receive a high level of site security, maintenance, and
technical support without the prohibitive costs of setting up and maintaining
their own server and Internet connection. We support most leading Internet
hardware and software system vendor platforms, including Solaris which operates
on a Sun Microsystems, Inc. platform, Microsoft Windows NT which operates on a
Intel/PC platform and Linux which operates on a Cobalt Networks, Inc. platform.
 
     Prices for dedicated hosting products marketed under the Sage Networks and
Interliant brands range from $100 to $5,000 a month, depending upon the hardware
configuration, bandwidth requirements and additional features that may be
requested by our customers. For certain customers of acquired businesses, the
price range may be lower. In 1998, our average dedicated hosting customer paid
$1,000 per month.
 
     Co-located Hosting.  We currently provide co-located hosting services in
our Atlanta and Washington, D.C. area data centers for customers with
sophisticated, mission-critical applications. This solution allows the customer
to own and access their servers on a 24x7 basis while delegating the day-to-day
management of their Web site to our IT specialists. In addition, co-located
servers are housed in separate, limited-access rooms in our data center. Prices
for co-located products marketed under our Sage Networks and Interliant brands
range from $500 to $40,000 a month, which incorporates fees such as bandwidth
charges and space. Bandwidth is the capacity of a telecommunications network to
carry voice, data and video information. For certain customers of acquired
businesses, the price range may be lower. In 1998, our average co-located
customer paid $750 per month.
 
     We also provide the following enhanced Internet services to our Web hosting
customers:
 
     E-commerce Capabilities.  Through our reseller relationships, we offer a
variety of e-commerce solutions to help businesses create and maintain a
successful Web storefront. E-commerce provides businesses the ability to sell
products and services on the Internet. The e-commerce capability can be added to
an existing Web site or it can be the basis for a Web site, starting with the
customer's product catalog. Representative e-commerce offerings include:
 
     - a full suite of Internet payment solutions offered by CyberCash, Inc.,
       including payment services for credit card, micropayment and Internet
       check transactions;
 
     - ShopSite from Open Market, Inc. which allows users to build quickly a
       simple catalog and begin taking orders; and
 
                                       38
<PAGE>   44
 
     - SoftCart from Mercantec which allows users to create sophisticated
       e-commerce Web sites that includes order taking, credit card processing
       and order fulfillment.
 
     Multimedia Hosting.  We allow our customers to include various multimedia
capabilities in their Web sites, including integrated text, graphics, video,
information and sound capabilities. With the acquisition of Telephonetics
International, Inc., we have added audio production and hosting capabilities to
the suite of Internet services available to our customers. In addition, we
provide our customers with the ability to include Real Networks and Microsoft
NetShow content within their Web sites.
 
     Community Hosting.  We allow customers of all sizes to include
community-building features such as e-mail and chat hosting. We provide POP or
Post Office Protocol e-mail boxes that can be used to send and receive e-mail
from any connection to the Internet and include unlimited aliases, forwarding
and auto-responders. We also offer chat hosting through our relationship with
eShare Technologies.
 
  APPLICATION HOSTING SERVICES
 
     We offer application hosting services which consist of groupware hosting
and application outsourcing solutions that provide its customers with 24x7
remote access to applications and data that are integral to their businesses.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
application hosting revenues comprised 51.3% of our revenues in the year ended
December 31, 1998 and 44.8% of our revenues for the three months ended March 31,
1999.
 
     Groupware Hosting.  We offer our customers a broad spectrum of groupware
hosting solutions for Lotus Notes/Domino, the industry-leading groupware
platform. Our groupware hosting solutions allow our customers who want to work
together collectively while located remotely from each other to store software
applications that facilitate this type of work environment on a computer that we
own and manage for them. Our groupware hosting services provide support for the
following:
 
     - feature-rich e-mail and other types of messaging for internal and
       external communication;
 
     - workgroup and project team collaboration and document sharing;
 
     - business process automation and workflow; and
 
     - proprietary or custom applications built for the groupware platform.
 
     We also can provide our customers with sophisticated, collaborative
Web-based intranets and extranet. An intranet is an Internet network which
usually belongs to a corporation and is accessible only by employees, or others
who have authorized access. An extranet is basically an intranet that provides
various levels of accessibility to outsiders who through a user name and
password can access selected parts of the extranet. We seek to provide the
following benefits to our customers hosting their groupware implementations with
us:
 
     - reduced deployment time and risk;
 
     - reduced day-to-day operational responsibility, allowing in-house IT
       departments to focus on creating strategic value;
 
     - lower ongoing cost;
 
     - no capital investment in servers, facilities and other infrastructure;
 
     - access to emerging technologies and improved responsiveness to change;
       and
 
     - 24x7 operations, high availability, rapid scalability and robust
       security.
 
     Customers generally pay monthly fees for the services offered, as well as
one-time fees for installation and deployment services. Customers typically sign
one- to three-year service contracts. Our customers have the option of using
shared or dedicated servers in one of our data centers for their groupware
hosting
 
                                       39
<PAGE>   45
 
services, or can have their on-premise server managed by our customer-managed
server offering. Prices for our groupware hosting services range from $1,500 to
over $100,000 a month.
 
     We provide hosting for groupware applications that are specifically
tailored for a Lotus Notes/Domino operating environment on both shared and
dedicated servers at one of our data centers or on the customer's premises. The
hosted servers support connections to:
 
     - geographically dispersed Lotus Domino servers for messaging and
       replication;
 
     - Lotus Notes clients for remote access to e-mail and Lotus Notes
       applications; and
 
     - Web browsers for intranets and extranets.
 
     Customers can connect to our servers using the Internet or a variety of
private network options, including frame relay, dedicated lines and local dialup
access in more than 160 countries. We provide messaging gateway services for
Lotus Domino, including:
 
     - Internet e-mail;
 
     - X.400 mail;
 
     - Lotus cc:Mail;
 
     - fax; and
 
     - a variety of pager networks.
 
     In addition, we and certain customers have established a Lotus
Domino/Microsoft Exchange messaging interoperability technology pilot program
which will allow users of both systems to communicate electronically, and we are
considering further expansion of this program to enhance our Microsoft Exchange
hosting offering.
 
     As part of our groupware hosting implementation process, we start with what
we believe to be the best available system configurations and work with our
customers to modify them to the customer's specific needs. Customers may choose
from a wide variety of hardware capacity and availability options, including
RAID, or Redundant Array of Inexpensive Disks, storage and full server
clustering. Once installed, we not only monitor server hardware, operating
system and application-level system performance, but also can provide full
server administration services including adding or deleting users, database
installation, access control changes and other required server administration
tasks.
 
     This groupware hosting service is also available for custom implementations
in conjunction with Interliant's consulting service offerings.
 
     Application Outsourcing.  Our application outsourcing offers customers an
integrated solution that combines packaged application software with managed
hosting services. We believe it is an industry leader in forging strategic
relationships with leading application developers and other key partners to
deliver these best-of-breed solutions. Through such strategic relationships, we
enable businesses of all sizes to capitalize on the latest Internet-enabled
technologies while outsourcing non-core business operations such as deployment
and migration strategies and maintenance or software upgrades to a third party.
Our branded application hosting services address the following major business
process areas:
 
   
     - Legal Automation.  Our legal automation solutions offer customers a suite
       of collaborative applications that assist attorneys in securely and
       reliably managing litigation, intellectual property matters and general
       workflow within corporate legal departments and law firms. These
       applications can be customized, deployed, supported and fully managed on
       dedicated or shared servers at our data centers. The legal automation
       suite of applications currently encompasses both Web-based and client
       server applications that are priced from $100 to $300 per user per month,
       as well as Internet rental applications that are priced as low as $20 per
       user per month.
    
 
                                       40
<PAGE>   46
 
     - Sales Automation.  Our sales automation services provide geographically
       distributed sales and marketing organizations with all the elements
       needed to quickly deploy a sales automation solution at a reasonable
       cost. These solutions include modules for
 
        - opportunity management;
 
        - contact and account management;
 
        - revenue forecasting reports;
 
        - an integrated group calendar;
 
        - automated proposal generator;
 
        - pricing information;
 
        - telesales campaign management; and
 
        - correspondence and fulfillment in a shared hosting environment.
 
        We believe that selling application outsourcing as part of a package of
      hosting services rather than as a product to be installed and managed by
      the customer, reduces the customer's initial capital investment, thereby
      making it easier to minimize the customer's technology risk. Accordingly,
      it also allows us to engage clients in long-term contracts with fixed
      monthly payments. The application solution is customized, deployed, and
      fully managed and supported by us, providing a single-source solution to
      customers. We partner with leading packaged commercial software vendors,
      hardware vendors and system integrators to deliver these solutions.
 
        Our sales automation services can be accessed through our secure network
      using a variety of dial-up or dedicated access methods on a 24x7 basis,
      leading to more efficient practices and effective communications. The
      solution can be easily configured to the customer's selling methodology
      and can be deployed within 30 days. The solutions range in price from $100
      to $200 per user per month depending upon the application features,
      hardware configuration and amount of disk storage needed.
 
     - Distributed Learning.  Distributed Learning over the Web represents a
       broad, horizontal market for us, with opportunities to deliver online
       training in virtually all market segments. Working with leading software
       technology vendors, best-of-breed content providers and business
       partners, we offer comprehensive solutions for corporate, academic, and
       non-profit customers. These solutions encompass:
 
        - browser based, asynchronous or any time, any place learning
          technologies;
 
        - browser based, synchronous or same time, any place learning
          technologies;
 
        - sophisticated course and student management systems;
 
        - online facilitation; and
 
        - application sharing.
 
     In addition, our distributed learning solutions leverage our core
     competencies:  Web hosting, multimedia technology and e-commerce, to
     deliver a complete package to our customers.
 
        Layering distributed learning know-how and functionality on top of its
      existing infrastructure services allows us to quickly deliver
      cost-effective solutions. Our Distributed Learning services are priced on
      a "per user, per course," or a "per person, per year" basis, with the
      typical cost of instruction per user per course in the range of $20 to
      $75. Costs are driven largely by the course's duration and complexity, as
      well as by the range of application level services that the customer
      desires. Deployment of existing courses is very rapid, with students
      typically able to access courses within a few days following registration.
 
     - Rental Applications.  We are is working to create a new generation of
       100% Web-based application solutions that are designed to be delivered as
       services over the Internet. No installation is required
 
                                       41
<PAGE>   47
 
       as users need only a Web browser and an Internet connection to select,
       set up, configure and use a rental application. Pricing models vary based
       on application usage models, but are all inclusive of the fees for
       application licensing, hosting, and basic support. We establish
       partnerships with software vendors to create these application services,
       many of which will be based on Lotus Domino Instant!Host, a platform for
       application hosting service providers co-developed by us and Lotus. We
       have established a portal site, www.appsonline.com, that contains a
       catalog for these Internet rental applications.
 
            Our first Internet rental application is Lotus Instant!TEAMROOM, a
       "teamware" collaboration tool available for a $14.95 monthly fee per end
       user which allows distributed teams to discuss issues, share documents,
       and track action items. Additional rental application services in
       development include teamware for specific vertical market segments, an
       application which allows companies to hold private auctions online, and
       more sophisticated collaboration tools for project management,
       calendaring and scheduling and document management.
 
  CONSULTING SERVICES
 
     We provide consulting services for Intranet, extranet and application
hosting solutions, as well as for internal networking implementations and
back-end Web development projects. In addition, we provide support for our
customers' enterprise networking needs. Our consulting services are scaled to
meet each client's needs. We address the complete spectrum of services,
including:
 
     - desktop and network server support;
 
     - network architecture and design;
 
     - local area network, wide area network and virtual private network design;
 
     - strategic technology planning;
 
     - application development and implementation; and
 
     - Web hosting.
 
     On a pro forma basis, giving effect to acquisitions completed to date,
consulting services revenues comprised 14.0% of our revenues in the year ended
December 31, 1998 and 16.0% of our revenues for the three months ended March 31,
1999.
 
ACQUISITION PROGRAM
 
     Since inception, we have acquired 16 companies and intend to continue its
acquisition program. Specifically, we seek to identify businesses which will
generate a positive return on investment and:
 
     - expand its customer base;
 
     - complement and expand its product and service offerings;
 
     - enhance its engineering and technical capabilities;
 
     - strengthen its reseller and referral partner relationships; and/or
 
     - broaden its management team.
 
We believe that the integration of acquired companies will create economies of
scale and generate significant operating efficiencies. Because of our ongoing
acquisition strategy, we expect that at all times some portion of its acquired
companies will be in various stages of integration. We seek to identify areas in
which acquired companies outperform its competitors and adopt their best
practices. Once we acquire a company, a multi-disciplinary team begins the
four-step integration process:
 
     Technical Integration.  Technical integration begins with the physical move
of the acquired company's equipment into one of our facilities. Generally, the
customers of the acquired company are then
 
                                       42
<PAGE>   48
 
migrated onto the our hosting platforms. Migration entails duplicating the
server contents onto a new server, which runs in parallel for a test period,
before being switched over. For Web sites with real-time databases or customized
applications, the process can become significantly more complex. Our platform is
typically more robust than that of the acquired company and standardization
allows us to manage the servers more efficiently. In certain circumstances,
however, Interliant finds that it is not strategic or cost-effective to migrate
customers to our platform.
 
     Customer Service Integration.  We integrate our customer service operations
for our acquired Web hosting customers at our data center in Atlanta and for our
application hosting customers in Houston. By centralizing hosting customer
service, we believe that it can improve performance while reducing costs. In
Atlanta, we have implemented the Vantive Support system, a customer/asset
management tracking application, which enables a customer service representative
to view a customer's entire account, including past and recent interactions with
the customer. Further, the Vantive Support system provides a resolution database
that recognizes and documents support records into a central repository that can
be accessed by all customer service personnel.
 
     Business Systems Integration.  Many of the businesses we acquire do not
have adequate back-office systems or procedures. As a result, we are in the
process of transitioning acquired companies onto the PORTAL Infranet billing
system. With PORTAL Infranet, our resellers, referral partners and customers
will be able to obtain monthly statements delivered electronically which we
believe will provide them with easy access to and accurate tracking of our
hosting expenditures. In particular, we believe that PORTAL will allow resellers
and referral partners to add new products and services, as well as pricing
discounts and incentive programs, in a timely and cost-effective manner.
 
     Product Integration.  We expect to integrate the majority of its acquired
companies into our product line, with uniform branding, pricing strategies and
distribution channels. In certain cases, however, where an acquired company's
brand is already established, we may for a period of time continue to market
certain products and services under the existing brand in order to capitalize on
the competitive advantages the acquired brand name may bring to us. Our
long-term goal, however, is to migrate most product offerings to our brand.

     We are currently engaged in discussions with respect to several
acquisitions. With respect to one of those acquisitions, we have entered into a
non-binding letter of intent. We cannot assure you that this transaction will be
consummated, or if consummated as to the terms of the transaction. The following
is a summary of the potential acquisition:
    
 
   
     - It is engaged in the virtual hosting business.
    
 
   
     - It had unaudited revenues of $2.8 million and (loss) of $(6.6) million
       for the year ended December 31, 1998.
    
 
   
     - Although we are currently renegotiating the letter of intent, we expect
       the consideration to be paid to be up to 1.7 million shares of common
       stock plus earnout consideration of up to an additional 500,000 shares of
       common stock.
    
 
CUSTOMERS
 
   
     We have established a diversified customer base across our service
offerings. Our customers include a variety of business types, ranging from small
office/home office companies through Fortune 500 companies. In addition, our
customers also include resellers of our services such as Web consulting firms,
Internet service providers, network integration companies and system integrators
who sell our services to their customers. We do not believe that the loss of any
one customer would materially adversely affect us.
    
 
   
     Web Hosting Customers.  Our contracts with our Web hosting customers
generally cover services for a period ranging from one month to two years. We

STRATEGIC RELATIONSHIPS
 
     Interliant's strategic relationships and partnerships with leading
technology companies allow it to provide a wide range of services to meet its
customers' needs. The following is a list of selected companies with whom
Interliant has a strategic relationship:
 
   
     IBM Corporation.  We are an IBM BESTeam partner and began offering the IBM
Net.Commerce Hosting Server product in January 1999. IBM currently lists
Interliant on its Web site as one of a select group of partners that are able to
offer this product. Interliant intends to introduce Net.Commerce hosting
services to our large reseller community as a world-class end-to-end e-commerce
solution. Interliant is also hosting IBM Net.Commerce Pro solutions for
dedicated server customers who maintain large e-stores and require large scale
implementations. There is no written contract that governs this relationship
with IBM and either of us can terminate this relationship at any time.
Currently, we do not have any financial commitments to IBM as a result of this
arrangement, and we do not expect this relationship to generate any material
financial commitments for us in the future.
    
 
     Lotus Development Corporation.  We believe we are a leading partner of
IBM's Lotus software division and are a Lotus Net Service Provider, Lotus Net
Service Provider/Alliance Partner, as well as a Lotus Premier Business Partner.
We provide a variety of messaging and hosting services for Lotus Notes/ Domino
Internet, intranet and extranet applications. We are currently listed by Lotus
on several sections of Lotus' Web site as one of a select group of partners that
provide hosting services for Lotus Notes/Domino and other Lotus application
solutions and have twice been recognized with Lotus' highest recognition, the
Lotus Beacon Award, most recently in January 1999.
 
     We are parties to a Joint Development Agreement with Lotus Development
Corporation, dated April 27, 1998, which is scheduled to expire on April 27,
2000, but will be automatically renewed for additional one year terms unless
terminated by either party upon prior written notice. Under this agreement,
together with Lotus we co-developed Lotus' Domino Instant! Host platform, which
enables
 
                                       45
<PAGE>   51
 
   
application developers to deploy and offer Web-based collaborative applications.
[Under the terms of this agreement, we share joint development responsibilities
with Lotus. Terms of this agreement include:
    
 
   
     - We are obligated to contribute proprietary computer code owned by us, to
      name one of our employees as the project liaison and to provide
      non-dedicated architectural and project management assistance to Lotus.
    
 
   
     - Lotus is obligated to contribute substantially similar type of
      intellectual property and personnel resources to the project.
    
 
   
     - Lotus is obligated to pay us a royalty equal to a percentage of the net
      revenues received from licensing Instant! Host.
    
 
   
     - We must pay Lotus at its standard rate for all copies of Instant! Host
      which we desire to license.
    
 
   
     - If Lotus engages in product development or promotional activities which
       impact its ability to generate revenues from the sale of Instant! Host,
       the agreement will terminate and Lotus will be obligated to pay us up to
       $250,000 in penalties depending upon the amount of royalties paid to us
       through the date of termination.
    
 
   
     Microsoft Corporation.  We are a Microsoft Certified Solution Partner
(MCSP) and are currently engaged in several strategic initiatives with
Microsoft. We have entered into a co-marketing and promotion agreement whereby
Microsoft will include our advertisements in a catalog that is inserted into
every FrontPage 2000 product box that is packaged for retail sale. Microsoft has
also agreed that it will issue a press release on its Web site highlighting our
joint involvement in the promotion of FrontPage 2000. In return, we have agreed
to feature Front Page 2000 on our Web site with greater frequency and visibility
than any competing product and have agreed to offer either free Web hosting with
a value of up to $105 or free or reduced registration and set-up fees with a
value of up to $500, in order to induce the public to host a FrontPage 2000 Web
site. This agreement remains in effect until the earlier of the initial release
of the next version of FrontPage, Microsoft ceasing to produce FrontPage, or
December 31, 2000.
    
 
   
     We are also participating in a Microsoft initiative called the Complete
Commerce program. In conjunction with selected other MCSP's, we will incent
customers seeking to engage in e-commerce activities on the Web to enter into
this program by offering a specially priced, all inclusive storefront hosting
package integrating shipping, credit card processing and tax elements. The
service will also include consulting and development of the storefront
application Web site, back-end integration and hosting activities. Microsoft
will provide resources to help us market this program, including promotional
activities, marketing activities and participation in the customer engagement
activities. Our marketing activities for the Complete Commerce program commenced
in April 1999. This relationship may be terminated at any time by either party.
We currently have no material financial commitments under either of these
agreements; and we do not expect either of these agreements to generate any
material financial commitments for us in the future.
    
 
   
     UUNET Technologies, Inc.  On February 17, 1999 we entered into an agreement
with UUNET to be our primary connectivity provider on a worldwide basis. The
agreement is scheduled to expire on February 19, 2002, but will be renewed
automatically for an additional year unless either party notifies the other of
its intent not to renew. Terms of this agreement include:
    
 
   
     - UUNET has agreed to provide and we have agreed to purchase minimum levels
       of connectivity from 100 Mbps to 600 Mbps of bandwidth.
    
 
   
     - Upon execution of this agreement we were committed to purchase 100 Mbps
       of bandwidth.
    
 
   
     - We must increase our bandwidth purchases to 300 Mbps of bandwidth by
       December 31, 1999 and 600 Mbps of bandwidth by December 31, 2000.
    
 
   
     - UUNET has agreed to significant discounts and competitive pricing
       assurances over the term of the agreement.
    
 
                                       46
<PAGE>   52
 
   
- - We have agreed that if during the second and third years of this agreement, we
  obtain over 600 Mbps of bandwidth for our Internet traffic, we will purchase a
  percentage of all bandwidth in excess of 600 Mbps from UUNET. If we do not
  purchase the agreed upon percentage of capacity from UUNET, we must pay UUNET
  a flat rate for each Mbps we are obligated but fail to purchase from them.
    
 
   
     Under the terms of the agreement, the connectivity may range in capacity
from T-1 to DS-3 to OC-12 which are the technical names of the physical
telecommunications connections or pipelines that will be used to transport data.
A larger pipeline can carry a greater volume of data at a greater speed. For
example, a T-1 can carry 1.544 megabytes per second; a DS-3 can carry 44.736
megabytes per second and an OC-12 can carry 622 megabytes per second. At our
Atlanta data center, we are currently installing four OC-3.
    
   
connections; each of which can carry 155.52 megabytes of data per second to
diverse hubs in UUNET's network utilizing diverse fiber for redundancy. In
addition to the connectivity provisions, our companies have agreed to develop
and implement a joint marketing program including:
    
 
     - allowing us to resell UUNET services through our network of resellers;
 
     - cooperating on mutually beneficial hosting and co-located remarketing
       agreements; and
 
     - cooperating on international co-location facilities agreement.
 
   
Our current financial commitments under this agreement are not material nor do
we expect our future financial commitments, including the increase in the
minimum bandwidth commitment and the possibility of having to pay penalties, to
be material.
    
 
   
     Equant, N.V.  We have entered into a Network Services agreement in which
Equant, N.V. provides worldwide local dialup (X.25 and PPP) and dedicated (frame
relay) connectivity from more than 160 countries. The original agreement expired
on December 31, 1997, and since then we have continually renewed it for
successive three month terms. The current term expires on June 30, 1999. Equant,
N.V. provides significant discounts to us and competitive pricing assurances. In
addition, Equant, N.V. has entered into a distribution agreement with us, in
which Equant, N.V.'s worldwide sales force is able to offer our groupware and
application hosting services to its customers. The distribution agreement
terminates on December 19, 1999 unless the parties agree to renew the agreement
by June 19, 1999. We currently have no material financial commitments under
either of these agreements; and we do not expect either of these agreements to
generate any material financial commitments for us in the future.
    
 
     Allaire Corporation.  Allaire markets and distributes proprietary
commercial computer software products such as Cold Fusion Enterprise Application
Server, Cold Fusion Professional Application Server and Home Site. We have a
worldwide non-exclusive fee-bearing license to:
 
     - reproduce exact copies of these software products onto its servers and to
       allow its customers to use these products;
 
     - reproduce exact object code copies of the products; and
 
     - market and distribute the products as stand-alone products or bundled
       with our other product offerings.
 
   
This one-year agreement commenced February 2, 1999 and will be automatically
renewed for another year unless either party notifies the other that it elects
not to renew within sixty days of the original termination date. Upon execution
of the agreement we paid Allaire an aggregate of $66,552 covering product user
and subscription fees, distribution copies, training fees and annual support
fees. We are also obligated to purchase five additional hosted copies, products
and subscriptions during each of the last three calendar quarters of the
original term of the agreement at an aggregate price of approximately $15,000
per quarter.
    
 
     In addition to the fees we pay for these licenses, we have agreed to
promote and market actively Allaire's products. We have also agreed to
participate in certain joint marketing and promotional activities.
 
     Elemental Software, Inc.  We have been granted a non-exclusive,
royalty-free license to market and resell Drumbeat(TM) 2000. By working with a
Drumbeat(TM) 2000 ISP Hosting Partner such as our company, organizations will be
able to publish data-driven Active Server Pages (ASP) applications without the
need
                                       47
<PAGE>   53
 
   
to set up and administer Web servers locally. As an ISP Hosting Partner, we also
provides hosting accounts for trial Drumbeat(TM) 2000 users. Under this
agreement, we are a Drumbeat(TM) 2000 reseller which means our customers receive
preferred pricing on each sale of Drumbeat(TM) 2000 generated through the
Elemental Software/Interliant e-commerce Web site. We have agreed to undertake
certain cross marketing activities to promote the launch of our partnership,
including press releases, Web advertising and a special promotion by us of
Drumbeat(TM) 2000. In addition, we have been given the opportunity to provide an
insert card to be included in the Drumbeat(TM) 2000 product packaging promoting
our services. This agreement which is dated December 13, 1998 may be terminated
by either Elemental or us with thirty days prior notice to the other. We do not
have nor do we expect to incur in the future any material financial commitments
as a result of this agreement.
    
 
   
     iMALL, Inc.  iMALL operates an Internet shopping mall and has created a
suite of e-commerce tools labeled iSTORE(TM) and Bolt-on e-commerce(TM).
Interliant and iMALL have agreed to use iMALL's experience and technical
infrastructure to create a mall where our customers can sell their products and
services online. Under the terms of the agreement, we pay iMALL for the use of
the Bolt-on e-commerce(TM) solution and iSTORE(TM) at various discounted rates
based on the number of iMALL accounts created by us. The aggregate amount of
fees payable under this agreement over the term of the agreement are not
material. Our agreement with iMALL states that it is intended to establish a
long-term relationship between us and iMALL and as such has a three-year term
which commenced on October 23, 1998.
    
 
     Revenues and expenses generated by these strategic relationships are
recognized on an accrual basis. Where appropriate, revenue and expenses are
matched.

SALES     INTERNET   TELESALES/      DIRECT
STRATEGY  MARKETING  INDIRECT SALES  SALES
</TABLE>
 
     We have historically used a variety of marketing and sales techniques,
including Internet marketing, telesales, indirect sales channels, such as
resellers and referral partners, and direct sales in order to increase its
market share. Our acquisition strategy has facilitated the integration of
different indirect and direct distribution channel models used by acquired
companies and has enabled us to customize them to fit the needs of specific
markets in which we compete.
 
     Internet Marketing.  Our Internet marketing sales program offers an
automated online sales interface to our customers that enables them to purchase
hosting services on a 24x7 basis from our Web site at www.interliant.com and
www.sagenetworks.com or purchase Internet rental application services at
www.appsonline.com.
 
     Telesales.  In the telesales area, we currently acquire, and plan to
develop further, our hosting accounts through inbound calls generated through
traditional media and outbound telesales to pre-qualified potential customers.
 
     Indirect Sales.  In the indirect sales channel area, our goal is to develop
the leading reseller and referral partner program in the industry through our
recently introduced business partner program. Our target partners include
reseller and referral partners, such as Web consulting firms, Internet service
providers, independent software vendors, network integration companies and
system integrators that have an established relationship with our prospective
customer base as well as a sales force capable of selling Internet services. The
benefits to us of using these indirect sales channels include greater market
reach without fixed overhead costs and the ability to use the partners to assist
in the delivery of complete
 
                                       49
<PAGE>   55
 
solutions to meet customer needs. We offer our partners a discount from our
retail price on both products and services.
 
     We believe that our business partner program offers its reseller and
referral partners a wide variety of benefits such as:
 
     - financial incentives including volume discounts and/or royalties, waived
       set up fees and advantageous software leasing opportunities;
 
     - access to our hosting services and applications;
 
     - advanced technical support;
 
     - sales and marketing support services; and
 
     - training and support programs.
 
     Direct Sales.  We have a sales group dedicated to selling hosting and
consulting solutions to large enterprises and other businesses whose Internet
operations are mission-critical.
 
   
     As of the date hereof, we have 53 employees engaged in distribution and
sales.
    
 
MARKETING
 
     We market our full range of hosting solutions under the SageNetworks and
Interliant brands via a marketing program that seeks to use a variety of media
and channels. We will continue to invest in building greater equity of the
Interliant brand worldwide, using a variety of marketing techniques including
print advertisements in key industry publications, broadcast advertising, direct
marketing and online advertising, such as general rotation and keyword-specific
Web banner advertisements. The focus of these branding efforts is primarily to
reinforce our position as a full service hosting provider. In addition, we will
also employ a number of other marketing tactics and communications vehicles,
such as product literature, trade shows, promotions with key hardware and
software vendors, direct response programs and our Web site to generate greater
numbers of qualified leads and to further increase awareness of our brand.
 
     When an acquired company's brand is already well-established, we may for a
period of time continue to market certain products and services under that brand
to capitalize on the competitive advantages the acquired brand may bring to us.
Our long-term goal, however, is to migrate most of our acquired product
offerings to our brands. Our products are available from our primary Web site at
www.interliant.com as well as at www.appsonline.com.
 
     We expect to increase our marketing expenditures in order to support our
brand marketing and lead-generation efforts. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
CUSTOMER SERVICE
 
   
     We view customer service as a critical part of our business strategy. Our
customer service group has 136 employees who are mainly located in our Atlanta
and Houston data centers. The customer service group is responsible for
providing customer service to all of our customers as well as our resellers and
referral partners, including helping customers to initially set up their Web
sites, answering technical questions or helping customers use our application
hosting solutions and other enhanced offerings. Through our customer service
systems, customer service representatives can generally resolve any issues in a
timely manner via e-mail or our toll-free number.
    
 
     Web Hosting Customer Service.  Our Web hosting customers are primarily
serviced through our Atlanta data center. To ensure that each Web hosting
customer is connected with the customer service representative best able to
address its needs, our call center routing system, provided by Aspect
Communications, directs calls based on the phone number dialed or the menu
choice selected. In addition, the Vantive Support system, a customer/asset
management tracking application, enables a customer
 
                                       50
<PAGE>   56
 
service representative to view a customer's entire account, including past and
recent interactions with such customer. Further, the Vantive Support system
provides a resolution database that recognizes and documents support records
into a central repository that can be accessed by all customer service
personnel. This database categorizes all reported problems so that if a
particular problem recurs, customer service representatives can view its prior
resolution and provide timely and accurate customer service. The Vantive Support
system is also linked to the Vantive Sales Force Automation module which helps
sales staff get current information on the status of accounts, recent problems
or account issues prior to calling customers to pursue new business
opportunities.
 
     In addition to the Aspect and Vantive systems, we are in the process of
implementing the PORTAL Infranet billing system. With PORTAL Infranet,
Interliant's resellers, referral partners and customers will be able to obtain
monthly statements delivered electronically which we believe will provide them
with easily accessible and accurate tracking of their hosting expenditures. In
particular, we believe that PORTAL will allow resellers and referral partners to
add new products and services, as well as pricing discounts and incentive
programs, in a timely and cost-effective manner.
 
     Application Hosting Customer Service.  Our application hosting customers
are primarily serviced through our Houston data center. Customers serviced in
Houston can contact a Technical Support Engineer on a 24x7 basis to address
issues including registration, mail routing, connectivity or enhancements to a
customer account such as rolling out new databases and changing access control
lists. Certain customer accounts also have access to dedicated support engineers
who are familiar with each unique configuration or requirement a larger customer
may have. A focused support team handles all the application hosting support
requirements via several mechanisms including a facilitated discussion database
environment available over the Internet where customers, application developers
and support technicians can discuss pertinent issues and build a relevant
knowledge base. Customers may also access support staff through e-mail as well
as through a toll-free number.
 
     On-line Customer Service.  We also provide resellers and customers who are
hosted in its Atlanta data center the opportunity to access an online control
panel which serves as a personalized, virtual customer service representative.
When fully implemented through PORTAL, this online control panel will enable
customers to find information they need such as billing histories, orders and
account profiles in a timely manner. In addition, at that time, the online
control panel will offer viewing of real-time billing statements and invoices,
the ability to order new or additional services, access to an online Web
development library, free applications and step-by-step guidance through common
Web publishing procedures. Thus, our resellers, referral partners and end users
hosted in Atlanta will have the option of accessing account and services
information themselves online or by calling the customer service centers.
 
TECHNOLOGY AND NETWORK OPERATIONS
 
     We have developed a secure, reliable, high-performance, and scalable
hosting solution, which we believe provides a significant competitive advantage
in the market. This solution is comprised of multiple hosting platforms that
incorporate automated functionality and a network infrastructure that includes
multiple Internet data centers and is monitored on a 24x7 basis by our personnel
in Atlanta and Houston. our strategy in developing our hosting solution focuses
on utilizing internally created technological innovations that we integrate with
leading software and hardware providers.
 
     Web Hosting Platform.  Although industry-standard Web servers are adequate
for basic Web hosting, we believe that efficiently managing large numbers of Web
sites and users on a single server requires significant technological
innovations. Accordingly, we have focused our technology development efforts on
creating various operating system level tools to facilitate a high customer to
server ratio. We have developed multiple Web hosting platforms that permit
efficient hosting of more than 5,000 Web sites on a Sun Microsystems, Inc.
Solaris server. We have also developed Web server applications designed to
improve performance in a virtual server environment and implemented resource
monitoring tools designed to report and address scarcity of shared computer
processing units and memory resources. Our solution is scalable, allowing
servers to be added while being monitored centrally independent of where they
are
 
                                       51
<PAGE>   57
 
located. To address the diverse requirements of our customers, we offer Web
hosting services on a range of operating systems and computing platforms
including Solaris which operates on a Sun Microsystems, Inc. platform, Microsoft
Windows NT which operates on an Intel/PC platform and Linux which operates on a
Cobalt Networks, Inc. platform.
 
     Application Hosting Platform.  We maintain a state-of-the-art data center
in Houston from which we manage our application hosting services. This facility
features separate, redundant fiber and power connections, diesel generators,
cooling systems and uninterruptible power supplies designed to provide on site
power for up to four weeks. Quality and security are paramount concerns for our
customer base. Consequently, we employ several security measures including:
 
     - 24x7 building guards;
 
     - electronic surveillance;
 
     - limited access electronic card key measures; as well as
 
     - the physical separation of servers from administrative workstations.
 
     The Houston facility includes high-end Compaq servers equipped with
multiple power supplies and RAID technology. Other strategic providers include
Sun Microsystems, Microsoft, and Lotus. We offer connectivity to our systems
from virtually anywhere in the world, enabling customers to deploy global
solutions. Customers can access us:
 
     - via the Internet;
 
     - through X.28 connections provided by Compuserve and Equant, N.V. in more
       than 160 countries;
 
     - over Frame Relay through AT&T Corp., Sprint Corporation and MCI Worldcom,
       Inc.; or
 
     - domestically via a toll-free number.
 
     We use two DS-3 connections to the Internet provisioned directly off a
SONET ring. Internally developed management and monitoring systems provide
insight into the performance of our entire network, as well as consistency of
security measures across all of our current hosting platforms.
 
     Network Operations.  In order to provide its customers with high-quality
service, we have invested substantial resources in building our network
infrastructure. We have designed our network to minimize the effect of any
interruptions. We have also implemented security measures and monitoring systems
to ensure that our network is protected, identify potential sources of failure,
limit downtime and notify staff of any problems. Although we have attempted to
build redundancy into our network and hosting facilities, our data centers are
currently subject to various single points of failure, and a problem with one of
our routers or switches could cause an interruption in the services we provide
to some of our customers.
 
     Our NOCs are responsible for monitoring our entire network on a 24x7 basis.
We monitor each piece of equipment, including routers, switches and servers. The
NOCs also monitor all Internet and telecommunications connections and ensures
that they are functional and properly loaded. The design of the NOCs enables
systems administrators and support staff to be promptly alerted to problems, and
we have established procedures for rapidly resolving any technical problems that
arise. The NOCs are fully integrated into our customer service facilities.
 
     We currently have two primary data centers located in Atlanta and Houston.
These data centers are fitted with continuous monitoring capabilities, back-up
generators and environmental controls to ensure high-quality service with
minimal interruptions. The Atlanta data center is our primary Web hosting
facility and the Houston data center is our primary groupware and application
outsourcing facility. The customer service and network monitoring
infrastructures are based in Atlanta and Houston.
 
     Our Virginia data center currently serves as a co-location facility. We
have recently entered into a ten-year lease for approximately 13,000 square feet
of space in Tysons Corner, Virginia. We intend to use a portion of the proceeds
from this offering to complete construction of this space and create a third
state-
 
                                       52
<PAGE>   58
 
of-the-art data center for hosting and providing customer service. Once the
construction of this new space is completed, all of our Washington, D.C. area
operations will be moved into the new space. See " -- Facilities" and "Use of
Proceeds."
 
COMPETITION
 
     The market served by us is highly competitive. Although barriers to entry
and continued growth are increasing, there are still few substantial barriers to
entry, particularly with respect to virtual hosting, and we expect that we will
face additional competition from existing competitors and new market entrants in
the future. The principal competitive factors in this market include:
 
     - quality of service, including network capability, scalability,
       reliability and functionality;
 
     - customer service and support;
 
     - variety of services and products offered;
 
     - price;
 
     - brand name;
 
     - Internet system engineering and technical expertise;
 
     - timing of introductions of additional value services and products;
 
     - network security;
 
     - financial resources; and
 
     - conformity with industry standards.
 
     We may not have the resources, expertise or other competitive factors to
compete successfully in the future.
 
     Our current and potential competitors include:
 
     - other Web hosting and Internet services companies such as AboveNet
       Communications, Inc., Exodus Communications, Inc., Frontier GlobalCenter,
       Globix Corporation and local and regional hosting providers;
 
     - national and regional Internet service providers such as Concentric
       Network Corporation, MindSpring Enterprises, Inc., UUNET Technologies,
       Inc., PSINet Inc. and Verio Inc.;
 
     - global telecommunications companies including AT&T Corp., British
       Telecommunications plc, Telecom Italia SpA and Nippon Telegraph and
       Telephone Corp.;
 
     - regional and local telecommunications companies, including the regional
       Bell operating companies such as Bell Atlantic Corporation and US West,
       Inc.;
 
     - companies that focus on application hosting such as USinternetworking,
       Inc. and IBM Global Services; and
 
     - audio and video content hosting companies such as broadcast.com.
 
     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 us. As
a result, certain of these competitors may be able to develop and expand their
network infrastructures and service offerings more rapidly, adapt to new or
emerging technologies and changes in customer requirements more quickly, take
advantage of acquisition and other opportunities more readily, devote greater
resources to the marketing and sale of their services and adopt more aggressive
pricing policies than can we. In addition, these competitors have entered and
will likely continue to enter into joint ventures or consortia to provide
additional services competitive with those provided by us.
                                       53
<PAGE>   59
 
     In an effort to gain market share, certain of our competitors have offered
hosting services similar to those of us at lower prices than those of us or with
incentives not matched by us. In addition, certain of our competitors may be
able to provide customers with additional benefits, which could reduce the
overall costs of their services relative to those of us. We may not be able to
reduce the pricing of its services or offer incentives in response to the
actions of its competitors without a material adverse impact on its operating
results. We also believe that the market in which we compete is likely to
encounter consolidation in the near future, which could result in increased
price and other competition that could have an adverse effect on our business.
 
INTELLECTUAL PROPERTY RIGHTS
 
     We rely on a combination of copyright, trademark, service mark, trade
secret laws and contractual restrictions to establish and protect certain
proprietary rights in its services. We have no patented technology that would
preclude or inhibit competitors from entering our market. The steps taken by us
to protect its intellectual property may not prove sufficient to prevent
misappropriation of our technology or to deter independent third-party
development of similar technologies. The laws of certain foreign countries may
not protect our services or intellectual property rights to the same extent as
do the laws of the United States. We also rely on certain technologies that it
licenses from third parties. These third-party technology licenses may not
continue to be available to us on commercially reasonable terms. The loss of the
ability to use such technology could require us to obtain the rights to use
substitute technology, which could be more expensive or offer lower quality or
performance, and therefore have an adverse effect on our business.
 
     To date, we have not been notified that its services infringe on the
proprietary rights of third parties, but third parties could claim infringement
by us with respect to current or future services. From time to time, we are
notified that the content of one of our customer's sites infringes on a third
party's trademark or copyright. In response, we inform the customer of such
claim and, if necessary, will terminate a customer's service. We expect that
participants in our markets will be increasingly subject to infringement claims
as the number of services and competitors in our industry segment grows. Any
such claim, whether meritorious or not, could be time-consuming, result in
costly litigation, cause service installation delays or require us to enter into
royalty or licensing agreements. Such royalty or licensing agreements might not
be available on terms acceptable to us or at all. As a result, any such claim
could have an adverse effect upon our business.
 
GOVERNMENT REGULATION
 
     We are not currently subject to direct federal, state or local government
regulation, other than regulations that apply to businesses generally. Only a
small body of laws and regulations currently applies specifically to hosting and
commerce activities, or access to the Internet. Due to the increasing popularity
and use of the Internet, however, it is possible that laws and regulations with
respect to the Internet may be adopted at international, federal, state and
local levels, 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. Although sections of the Communication Decency Act of 1996 (the
"CDA") that, among other things, 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 CDA could subject us and/or its customers to
potential liability, which in turn could have a material adverse effect on our
business, results of operations and financial condition. The adoption of any
such laws or regulations might decrease the growth of the Internet, which in
turn could decrease the demand for the services of us or increase the cost of
doing business or in some other manner have an adverse effect on our business.
 
     We currently do not collect sales or other taxes with respect to the sale
of services or products in states and countries where we believe we are not
required to do so. We do collect sales and other taxes in the states we have
offices and are required by law to do so. One or more jurisdictions have sought
to
                                       54
<PAGE>   60
 
impose sales or other tax obligations on companies that engage in online
commerce within their jurisdictions. A successful assertion by one or more
jurisdictions that we should collect sales or other taxes on our products and
services, or remit payment of sales or other taxes for prior periods, could have
an adverse effect on our business.
 
     In addition, applicability to the Internet of existing laws governing
issues such as property ownership, copyright 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. Changes to such laws intended
to address these issues could create uncertainty in the marketplace that could
reduce demand for the services of Interliant or increase the cost of doing
business as a result of costs of litigation or increased service delivery costs,
or could in some other manner have an adverse effect on our business.
 
     Any new legislation or regulation, or the application of laws or
regulations from jurisdictions whose laws do not currently apply to our
business, could have an adverse effect on our business.
 
EMPLOYEES
 
   
     As of the date hereof, we have 500 employees (including 19 on a contract
basis), of which 87 are in sales, distribution and marketing, 175 are in
engineering and service development, 136 are in customer service and technical
support, 94 are in finance and administration and 8 in acquisition integration.
We believe that our future success will depend in part upon our continued
ability to attract, hire and retain qualified personnel. Although we believe we
have thus far been successful in this endeavor (including a high retention rate
of key employees from acquired companies), the competition for such personnel is
intense, and we may not be able to identify, attract and retain such personnel
in the future. None of our employees are represented by a labor union, and
management believes that our employee relations are good.
    
 
FACILITIES
 
     Our executive offices are located in Cambridge, Massachusetts and consist
of approximately 7,800 square feet that are leased pursuant to an agreement that
expires in June 1999. Although we have not yet entered into a definitive
agreement, we are in negotiations for the lease of office space in Purchase, New
York. We intend to relocate our executive offices to such space as soon as
possible after execution of a lease. We also lease approximately 15,740 square
feet in Atlanta, Georgia under an agreement that expires in June 2003 and
approximately 1,000 square feet of space in McLean, Virginia area under a lease
that expires in July 2001. We also lease 59,885 square feet of space in Houston,
Texas under an agreement that expires in August 2001 and office space in London,
England. In addition, we have recently leased approximately 13,000 square feet
of space in Tysons Corner, Virginia under a lease that expires in 2009. A
portion of the proceeds of this offering will be used by us to complete and
equip this space. Once the construction of this space is completed, all of our
McLean, Virginia operations will be moved into this space. See "Use of Proceeds"
and "Business -- Technology and Network Operations."
 
LEGAL PROCEEDINGS
 
     In the ordinary course of business, we may be involved in legal proceedings
from time to time. As of the date of this prospectus, there are no material
legal proceedings pending against us.

OPTION GRANTS IN LAST FISCAL YEAR
 
     None of the named executive officers were granted options in the last
fiscal year. On April 15, 1999, our Compensation Committee granted an aggregate
of 375,000 options to senior management, including:
 
     - options to purchase 30,000 shares of common stock at an exercise price of
       $8.00 per share to Stephen W. Maggs;
 
     - options to purchase 30,000 shares of common stock at an exercise prices
     of $8.00 per share to
      Rajat Bhargava;
 
     - options to purchase 25,000 shares of common stock at an exercise price of
       $8.00 per share to Francis J. Alfano;
 
     - options to purchase 25,000 shares of common stock at an exercise price of
     $8.00 per share to
      Bruce S. Klein; and
 
     - options to purchase 25,000 shares of common stock at an exercise price of
       $8.00 per share to William A. Wilson.
 
STOCK OPTION PLAN
 
     Our Board of Directors has adopted and our stockholders have approved the
Interliant 1998 Stock Option Plan, under which stock options may be granted to
our officers, employees and consultants and to officers, employees and
consultants of our subsidiaries. Our stock option plan allows our Board of
Directors to award up to an aggregate of 3,800,000 options to purchase an
identical number of shares of our common stock to qualified recipients. As of
the date of this prospectus, our Board has granted a total of 3,697,994 options.
Any options which have been granted but which expire or terminate unexercised
are returned to the plan and may be granted at a later date to any qualified
recipient.
 
     Our stock option plan is administered by the Compensation Committee of the
Board of Directors. The Committee has the authority to determine:
 
     - the persons to whom options will be granted;
 
     - when options will be granted;
 
     - the number of shares subject to each option;
 
     - the exercise price of each option;
 
     - the time or times at which the options will become exercisable;
 
     - the duration of the exercise period; and
 
     - provide for the acceleration of the exercise period.
 
In addition, if we are involved in a merger, reorganization, stock split or
other type of corporate transaction that would diminish the value of our
outstanding options, the Compensation Committee may adjust the number of options
granted and/or the exercise price of such options in order to ensure that option
holders are treated equitably.
 
     Our stock option plan also permits the grant of stock options that qualify
as incentive stock options ("ISOs") under Section 422 of the Internal Revenue
Code and nonqualified stock options ("NSOs"), which do not so qualify.
 
     The exercise price of options granted under our stock option plan may not
be less than 100% of the fair market value of the common stock on the date of
grant. The maximum term of options granted under our stock option plan is 10
years from the date of grant. ISOs granted to any employee who is a 10%
shareholder of Interliant are subject to special limitations relating to the
exercise price and term of the options. The value of common stock subject to
ISOs that become exercisable by any one employee in any one year is limited by
the Internal Revenue Code to $100,000. For this purpose, the value of common
                                       61
<PAGE>   67
 
stock is determined at the time of grant. Options granted under our stock option
plan will generally become vested and exercisable over a four-year period in
equal annual installments. However, if any of the events listed below occurs and
provided that no written provision has been made, in connection with any such
event, for (1) the continuation of the stock option plan and/or the assumption
of all outstanding options by a successor corporation, or (2) the substitution
for such options of new options covering the stock of a successor corporation
then each option that was not then vested prior to such event will become fully
vested and immediately exercisable:
 
     - An acquisition by any person or group of related individuals of
       beneficial ownership of 30% or more of either the outstanding shares of
       our common stock or the combined voting power of our outstanding voting
       securities;
 
     - A change in the composition of our Board of Directors during any period
       of two consecutive years which results in the directors in office at the
       beginning of such period plus any newly elected or nominated directors no
       longer constituting at least a majority of our Board of Directors;
 
     - The approval by our stockholders of a merger, consolidation or
       reorganization in which outstanding shares of our common stock are
       converted into:
 
        - shares of stock of another company, unless our stockholders end up
          owning 80% or more of the voting power of such other company;
 
        - other securities of our company or another company unless our
          stockholders hold at least 80% of the voting power of our company or
          such other company; or
 
        - cash or other property;
 
     - The approval by our stockholders of the sale or other disposition of all
       or substantially all of our assets or our liquidation of dissolution; or
 
     - The adoption by our Board of Directors of a resolution to the effect that
       any person has acquired effective control of our business and affairs.
 
     All options granted under our stock option plan may not be transferred,
except upon the death of the optionholder in accordance with his will or
applicable law. In the event of an optionee's death or permanent and total
disability, outstanding options that have become exercisable will remain
exercisable for a period of one year, and the Committee will have the discretion
to determine the extent to which any unvested options shall become vested and
exercisable in connection with such death or disability. In the case of any
other termination of employment, except for a termination for cause as described
below, outstanding options that have previously become vested will remain
exercisable for a period of 90 days. All unexercised options will be immediately
forfeited by any employee who is terminated as a result of any of the following:
 
     - embezzlement or misappropriation of corporate funds;
 
     - conviction for a felony;
 
     - misconduct resulting in material injury to us;
 
     - significant activities harmful to our reputation of the reputation or any
       of our subsidiaries;
 
     - a significant violation of our corporate policies;
 
     - willful refusal to perform, or substantial disregard of, the duties
       properly assigned to the option holder;
 
     - a significant violation of any contractual, statutory or common law duty
       of loyalty to us or any of our subsidiaries.
 
                                       62
<PAGE>   68
 
     Under our stock option plan, the exercise price of an option is payable in
cash or, in the discretion of the Committee, in common stock or a combination of
cash and common stock. An optionee must satisfy all applicable tax withholding
requirements at the time of exercise.
 
     Our stock option plan has a term of 10 years, and all options granted under
the Plan prior to its termination remain outstanding until they have been
exercised or are terminated in accordance with their terms. Our Board of
Directors may amend the Plan at any time.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Mr. Dircks and Ms. Riley served as members of our Compensation Committee
during fiscal year 1998. During 1998, no committee member was an officer or
employee of ours. In addition, no interlocking relationship exists between our
Board of Directors or our Compensation Committee and the board of directors or
compensation committee of any other company, nor has any such interlocking
relationship existed in the past.
 
EMPLOYMENT AGREEMENTS
 
     We have entered into employment agreements with Messrs. Fassler, Maggs and
Bhargava, pursuant to which each will receive annual compensation of $180,000.
The Agreements provide for a term of one year and will renew automatically for
additional one-year terms unless we or the employee deliver a notice of
non-renewal at least three months prior to termination of the term. Under the
Agreements, the employees are also entitled to participate in our employee
benefit plans which are generally available to our senior officers.
 
     The Agreements include provisions that are effective upon the termination
of employment of the employees under certain circumstances. In general, the
employees are entitled to severance upon termination by us without "cause". The
severance shall be equal to the amount of the employee's base salary yet to be
paid for the unexpired portion of the term of the Agreement, discounted based on
a specified published interest rate. In the event of termination due to death or
disability for a specified period of time, the employee or the employee's
estate, as applicable, shall be entitled to receive one-year's base salary,
discounted based on a specified published interest rate and we shall continue to
provide the employee, his spouse and minor children, as applicable, with certain
medical and other benefits through the end of the term of the Agreement.
 
     For our protection, the agreements prohibit Messrs. Fassler and Bhargava
during and for periods of twenty-four and twelve months, respectively after the
end of their individual employment, from:
 
     - Soliciting any customers which are in any way related to our business;
 
     - Competing with us in any way; or
 
     - Disclosing or enabling anyone else to use any information he obtains
       during his employment.
 
     Each Agreement also prohibits Messrs. Fassler and Bhargava from:
 
     - Interfering or attempting to disrupt our business relationship with
       customers or suppliers; or
 
     - Soliciting our employees.
 
   
     The prohibitions contained in Mr. Maggs's contract are identical to those
contained in Mr. Fassler's contract, except Mr. Maggs is not prohibited from
engaging in Internet related business activities through Channel Reps, Inc. or
any of its subsidiaries or divisions or Channel Force, Inc.
    
 
     Mr. Feld, through Intensity Ventures, Inc., has entered into a one-year
consulting agreement with us with substantially identical terms to the
agreements described above, except that Mr. Feld is not prohibited from
competing with us and is not entitled to participate in our employee benefit
plans. His annual consulting fee of $180,000 will be paid to Intensity Ventures,
Inc. on a gross basis as an independent contractor.
 
                                       63
<PAGE>   69
 
     We have also entered into a two-year employment agreement with Mr. Lidestri
which shall automatically be extended on a month-to-month basis from the end of
the term unless we or Mr. Lidestri deliver a notice stating a desire to
terminate the agreement. The agreement provides for an annual base salary of
$180,000 and an annual bonus of up to $70,000 based upon whether Mr. Lidestri
meets or exceeds specified performance objectives. In addition, under the
agreement, We are obligated to pay Mr. Lidestri a signing bonus of $150,000 with
$100,000 of such bonus having been paid in April 1999 and the remaining $50,000
of which is payable on the first anniversary of the agreement.
 
     Under the agreement, Mr. Lidestri is entitled to participate in our
employee benefit plans which are generally available to our employees. The
agreement states that upon termination of Mr. Lidestri's employment by us
without cause or by Mr. Lidestri as allowed under the agreement, he shall be
entitled to severance comprised of the following components:
 
          - any remaining unpaid portion of his signing bonus; plus
 
          - the greater of (A) the unpaid portion of his annual base salary and
            other compensation for the remainder of the term of the agreement,
            including a pro rata portion of the performance-based bonus for the
            year in which his employment is terminated, or (B) an amount equal
            to six months of his annual base salary and other compensation for
            the remainder of the term of the agreement plus a pro rata portion
            of the performance-based bonus for the year in which his employment
            is terminated.
 
     In addition, Mr. Lidestri shall be entitled to participate in our benefit
programs for a minimum of six months from the date of termination.
 
     If we terminate the agreement for cause, Mr. Lidestri shall be entitled to
receive only the unpaid portion of his base salary and all vested benefits under
any benefit programs, in each case, through the date of termination.
 
     In the event of termination due to death or disability during the term of
the agreement, Mr. Lidestri or Mr. Lidestri's estate, as applicable, shall be
entitled to receive all accrued and unpaid portions of his annual base salary to
the date of his death or disability and all employee benefits accrued but unpaid
to the date of his death or disability.
 
     Under the terms of the agreement for a period of time following termination
of Mr. Lidestri's employment with us, which shall be either one year from such
termination, one year following the expiration of the agreement or two years
following the date of the agreement depending upon the reason for termination,
Mr. Lidestri is prohibited from engaging in the following activities:
 
     - Competing with us or any of our subsidiaries in any way, except as an
       officer, director, shareholder or employee of ours or any of our
       affiliates.
 
     - Soliciting or interfering with, or attempting to hire:
 
          - any person who was employed by us or one of our affiliates or
            subsidiaries during the 12 months before the end of the agreement;
 
          - any person who was a customer or client or requested or received a
            proposal from us or one of our affiliates or subsidiaries during the
            12 months before the end of the agreement; or
 
     - Using, disclosing or publishing any confidential material related to our
       business or the business of any of our subsidiaries or affiliates which
       he acquired while employed with us, unless the material is publicly
       available, otherwise lawfully obtained or must be disclosed by law.

FEES PAID BY US TO OUR SIGNIFICANT STOCKHOLDERS
 
     During 1999 and 1998, in connection with certain of our acquisitions, we
paid or accrued transaction fees of approximately $361,000 and $337,000,
respectively, to Charterhouse, which is an affiliate of CEP III. Such fees were
paid pursuant to the terms of the WEB LLC Agreement which require WEB or its
affiliates, which includes us, to pay Charterhouse two percent (2%) of the total
transaction costs of each acquisition or investment by WEB or its affiliates,
which includes us, in which Charterhouse or any of its affiliates directly or
indirectly provide all or a portion of the equity financing therefor.
Charterhouse will not receive any fees with respect to this arrangement in the

(1) Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission, based on factors including voting and
    investment power with respect to shares. Shares of common stock subject to
    options currently exercisable within 60 days of April 30, 1999 are deemed
    outstanding for the purpose of computing the percentage of ownership of the
    person holding such options, but are not deemed outstanding for computing
    the percentage ownership of any other person.

                          DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED STOCK; ISSUED AND OUTSTANDING SHARES
 
     Our authorized capital stock consists of 200,000,000 shares of common
stock, par value $0.01 per share, and 1,000,000 shares of undesignated preferred
stock, par value $0.01 per share.
 
COMMON STOCK
 
   
     Following the offering 41,663,045 shares of common stock will be issued and
outstanding based on the number of shares of common stock outstanding as of the
date hereof and assuming the issuance of 2,647,658 shares of common stock upon
the conversion of all outstanding Series A Redeemable Convertible Preferred
Stock (see "-- The SOFTBANK Investment"). All of the issued and outstanding
shares of common stock are, and the shares of common stock offered hereby will
upon completion of this offering be fully paid and nonassessable.
    
 
     The following summarizes the rights of holders of our common stock:
 
     - each holder of shares of common stock is entitled to one vote per share
       on all matters to be voted on by stockholders generally, including the
       election of directors;
 
     - there are no cumulative voting rights;
 
     - the holders of our common stock are entitled to dividends which may be
       paid in cash, property or shares of our capital stock and other
       distributions as may be declared from time to time by the board of
       directors out of funds legally available for that purpose, if any;
 
     - upon our liquidation, dissolution or winding up, the holders of shares of
       common stock will be entitled to share ratably in the distribution of all
       of our assets remaining available for distribution after satisfaction of
       all our debts and liabilities and the payment of the liquidation
       preference of any outstanding preferred stock; and
 
     - upon completion of this offering, the holders of common stock have no
       preemptive or other subscription rights to purchase shares of our stock,
       nor will holders be entitled to the benefits of any redemption or sinking
       fund provisions.
 
   
     As of the date hereof, there were approximately 45 record owners of common
stock.
    
 
     Certain stockholders of Interliant have been given the right to nominate
persons for election as directors. See "-- The SOFTBANK Investment" and "-- The
Interliant Acquisition."
 
PREFERRED STOCK
 
     Our certificate of incorporation authorizes our board of directors to
create and issue one or more series of preferred stock and determine the rights
and preferences of each series within the limits set forth in our certificate of
incorporation and applicable law. Among other rights, the board of directors may
determine, without further vote or action by our stockholders:
 
     - the number of shares constituting the series and the distinctive
       designation of the series;
 
     - the dividend rate on the shares of the series, whether dividends will be
       cumulative, and if so, from which date or dates, and the relative rights
       of priority, if any, of payment of dividends on shares of the series;
 
     - whether the series will have voting rights in addition to the voting
       rights provided by law and, if so, the terms of such voting rights;
 
     - whether the series will have conversion privileges and, if so, the terms
       and conditions of conversion;
 
     - whether or not the shares of the series will be redeemable or
       exchangeable, and if so, the dates, terms and conditions of redemption or
       exchange, as the case may be;
                                       69
<PAGE>   75
 
     - whether the series will have a sinking fund for the redemption or
       purchase of shares of that series, and, if so, the terms and amount of
       the sinking fund; and
 
     - the rights of the shares of the series in the event of our voluntary or
       involuntary liquidation, dissolution or winding up and the relative
       rights or priority, if any, of payment of shares of the series.
 
     Unless otherwise provided by our Board of Directors, the shares of all
series of preferred stock will rank on a parity with respect to the payment of
dividends and to the distribution of assets upon liquidation. Although we have
no present plans to issue any shares of preferred stock, any future issuance of
shares of preferred stock, or the issuance of rights to purchase preferred
shares, may have the effect of delaying, deferring or preventing a change of
control in our company or an unsolicited acquisition proposal. The issuance of
preferred stock also could decrease the amount of earnings and assets available
for distribution to the holders of common stock or could adversely affect the
rights and powers, including voting rights, of the holders of the common stock.
Accordingly, the issuance of shares of preferred stock may discourage bids for
the common stock at a premium or may otherwise adversely affect the market price
of the common stock.
 
     Currently, excluding 2,647,658 shares of Series A Redeemable Convertible
Preferred Stock that will be converted into an equal number of shares of common
stock upon the consummation of this offering and which will then cease to exist
(see "Description of Capital Stock -- The SOFTBANK Investment"), there are no
shares of preferred stock issued or outstanding.
 
THE WEB HOSTING ORGANIZATION INVESTMENT
 
   
     WEB owns 25,200,000 shares of our common stock, which will represent
approximately 60.5% of our outstanding common stock following consummation of
this offering. The shares were acquired for an aggregate purchase price of $42.0
million in a series of 6 transactions in December 1997, May 1998, June 1998,
September 1998, December 1998 and February 1999, in each case at a price, giving
effect to the 3-for-1 stock split effective in July 1998, of $1.67 per share.
The terms of the sale and purchase of these shares are set forth in a
subscription agreement dated December 8, 1997 between WEB and us. The principal
members of WEB are (1) CEP III, which is an affiliate of Charterhouse and (2)
WHO (collectively with CEP III, the "WEB Members"), of which Leonard J. Fassler
and Bradley A. Feld are the member managers. The WEB Members have agreed that
WEB shall be under the exclusive direction of a management committee comprised
of seven members and will vote such member's interest in WEB so that a majority
of the members of such management committee will be designees of Charterhouse.
WEB has certain demand and incidental registration rights under the terms of an
Investors Agreement dated as of January 28, 1999 and a Registration Rights
Agreement dated as of December 8, 1997. See "Description of Capital
Stock -- Registration Rights of Certain Holders."
    
 
THE SOFTBANK INVESTMENT
 
     On January 28, 1999, the SOFTBANK Purchasers purchased from an aggregate of
2,647,658 shares of our Redeemable Convertible Preferred Stock and warrants to
purchase 749,625 shares of our common stock for an aggregate purchase price of
$13.0 million. On April 19, 1999, the SOFTBANK Purchasers exercised their
warrants at an aggregate exercise price of $5.0 million and now own 749,625
shares of our common stock. Upon the consummation of this offering, all of the
outstanding shares of Redeemable Convertible Preferred Stock will automatically
be converted into an equal number of shares of our common stock, and the
SOFTBANK Purchasers will own approximately 8.2% of our outstanding common stock.
Bradley A. Feld, our Co-Chairman and director, is a general partner of the
SOFTBANK Purchasers. See "Related Party Transactions." The SOFTBANK Purchasers
have certain demand and incidental registration rights under the terms of the
Investors Agreement. See "Registration Rights of Certain Holders." A majority in
interest of the SOFTBANK Purchasers also have the right, under the Investors
Agreement, to nominate one person for election to our Board of Directors and
have the Board cause that director to be a member of the Compensation Committee
and/or the Audit Committee of the
 
                                       70
<PAGE>   76
 
Board. Such director will be subject to removal by the SOFTBANK Purchasers at
any time, with or without cause, and the SOFTBANK Purchasers will have the right
to call a special meeting of stockholders at any time for the sole purpose of
removing and replacing such director. WEB has agreed to vote its shares in a
manner consistent with these and the other terms of the Investors Agreement. Mr.
Charles R. Lax is currently serving as a director and a member of the
Compensation Committee of our Board of Directors pursuant to such provisions.
 
THE INTERLIANT ACQUISITION
 
     On March 10, 1999, pursuant to an Asset Purchase Agreement with Interliant
Texas and the shareholders of Interliant Texas, we, partly through a
wholly-owned subsidiary, acquired substantially all of the assets and assumed
specified liabilities of Interliant Texas for $100,000 in cash, 4,091,642 shares
of common stock and the assumption of promissory notes in favor of Mathew Wolf
and Erving Wolf in the aggregate amount of $15.9 million. Upon the closing of
the acquisition, the $7.9 million note in favor of Erving Wolf was paid in full
and the $8.0 million note issued by Interliant Texas in favor of Mathew Wolf was
canceled and replaced by the Wolf Note. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
     The 4,091,642 shares of common stock issued in connection with the
acquisition were delivered pursuant to an Agreement to Deliver Shares which
provided, among other things, for 3,608,863 shares of common stock to be
delivered at the closing of the acquisition to the shareholders of Interliant
Texas, 114,644 shares of common stock to be delivered at the closing of the
acquisition to Broadview Holdings LLP, 18,135 shares of common stock to be
delivered on the first business day following January 1, 2000 and 350,000 shares
of common stock to be placed in escrow to support the indemnification
obligations of Interliant Texas and its shareholders under the Purchase
Agreement. Unless we make a claim against the escrowed shares in accordance with
the provisions of the Purchase Agreement, the shares of common stock placed in
escrow will be distributed to Mathew Wolf, one of the shareholders of Interliant
Texas, on March 31, 2000.
 
     In addition, under the Purchase Agreement, we issued 2,322,139 options to
purchase shares of our common stock at an exercise price of $0.13 per share. All
or a portion of such Interliant Options are fully vested and exercisable.
 
     The Shareholders have certain incidental registration rights under the
terms of the Shareholders Agreement, dated as of March 10, 1999 by and among all
of our shareholders. See "-- Registration Rights of Certain Holders."
 
     For so long as all of the parties who received shares of common stock
pursuant to the Agreement to Deliver Shares and certain holders of our options
own in the aggregate 5% of more of the issued and outstanding common stock, such
parties shall have the right to nominate one person for election to our Board of
Directors. To date, such parties have not exercised such rights.
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
     We have granted the holders of an aggregate of 32,320,790 shares of common
stock certain demand and incidental registration rights. The SOFTBANK Purchasers
have such registration rights under the Investors Agreement with respect to
2,647,658 shares of common stock to be received upon the consummation of this
offering from the conversion of an equal number of shares of Redeemable
Convertible Preferred Stock and 749,625 shares of common stock received on April
19, 1999 upon the exercise of warrants. WEB has such registration rights under
the terms of each of the Investors Agreement and the Registration Rights
Agreement with respect to 25,200,000 shares of common stock purchased. The
Seller Shareholders have incidental registration rights under the terms of the
Shareholders Agreement with respect to 3,608,863 shares of common stock received
as consideration for the sale of substantially all of the assets of Interliant
Texas and Broadview Holdings LLP has incidental registration rights with respect
to 114,644 shares owned by it. The Shareholders Agreement provides that it shall
be amended as
 
                                       71
<PAGE>   77
 
necessary to include any additional shares of common stock issuable pursuant to
the provisions in the Purchase Agreement regarding adjustment of purchase price.
 
     If we propose to file a registration statement under the Securities Act
covering our common stock or any securities exercisable or exchangeable for or
convertible into our common stock holders of piggyback registration rights may
require us to include a requested amount of their common stock in our registered
offering on the same terms and conditions applicable to the other equity
securities included in such registration statement. We may reduce the number of
shares to be registered if the managing underwriter determines that the
inclusion of such shares would materially and adversely affect the success of
this offering. These piggyback registration rights do not apply to the
registration of securities in connection with our employee benefit plans or
securities issuable in a merger, exchange offer or similar transaction.
 
     Demand registration rights entitle the holder to require us to include a
requested amount of their common stock in a registration statement on Form S-1,
Form S-2 or Form S-3 and to use our best efforts to register such shares under
the Securities Act of 1933, as amended based on the advice of the managing
underwriter. A majority of the SOFTBANK Purchasers may exercise two demand
registration rights with respect to the registration of shares of common stock
on Form S-1, and twenty percent of the SOFTBANK Purchasers may exercise two
demand registration rights with respect to the registration of shares of common
stock on Form S-3 at any time we become eligible to use Form S-3. WEB may
exercise three demand registration rights with respect to the shares of common
stock that it owns. However, we are not required to register shares under demand
registration rights sooner than six months following the consummation of this
offering.
 
     Each stockholder with the foregoing piggyback registration rights and
demand registration rights whose shares of common stock are included in a
registration statement must agree not to offer for public sale any shares of
common stock or securities exercisable or exchangeable for or convertible into
common stock, or effect any sale of securities pursuant to Rule 144 under the
Securities Act of 1933, as amended, during the ten days prior to and the 180
days after the closing date of any underwritten offering unless such shares are
covered by such registration statement or a shorter period is agreed to by the
managing underwriter. We are required to bear all related registration expenses
(excluding any underwriting discounts or commissions, if any), disbursements and
fees in connection with the exercise of Piggyback Registration Rights and Demand
Registration Rights.
 
     In addition, in connection with the issuance to Mr. Steven C. Dabbs of
150,000 shares of common stock in connection with the acquisition of
substantially all of the assets of Clever Computers, Inc., we have agreed that
in the event we grant registration rights with respect to shares of common stock
to any other employee of Interliant or its affiliates, employed in a position
comparable or junior to Mr. Dabbs, identical registration rights shall be given
to Mr. Dabbs.
 
LIMITATIONS ON DIRECTOR LIABILITY
 
     Our certificate of incorporation provides that, to the fullest extent
permitted by the Delaware General Corporation Law, none of our directors will be
personally liable to us or our stockholders for monetary damages. Section
102(b)(7) of the Delaware General Corporation Law currently provides that a
director's liability for breach of fiduciary duty to a corporation may be
eliminated, except for liability:
 
     - for any breach of the director's duty of loyalty to the corporation or
       its stockholders;
 
     - for acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;
 
     - under Section 174 of the Delaware General Corporation Law, for unlawful
       dividends or unlawful stock repurchases or redemptions; and
 
     - for any transaction from which the director derives an improper personal
       benefit.
 
     Any amendment to these provisions of the Delaware General Corporation Law
will automatically be incorporated by reference into our certificate of
incorporation without any vote on the part of its
                                       72
<PAGE>   78
 
stockholders unless otherwise required, including this provision in our Amended
and Restated Certificate may, however, discourage or deter stockholders or
management from bringing a lawsuit against directors for a breach of their
fiduciary duties, even though such an action, if successful, might otherwise
have benefit us and our stockholders.
 
     The By-laws provide that we will indemnify our directors and officers to
the fullest extent permitted by Delaware law. Generally, we are required to
indemnify our directors and officers for all:
 
     - judgments;
 
     - fines;
 
     - settlements;
 
     - legal fees; and
 
     - other expenses
 
incurred in connection with pending or threatened legal proceedings because of
the director's or officer's position with us.
 
SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW
 
     We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. Under Section 203, business combinations between a Delaware
corporation whose stock generally is publicly traded or held of record by more
than 2,000 stockholders and an interested stockholder are generally prohibited
for a three-year period following the date that such a stockholder became an
interested stockholder, unless:
 
     - the corporation has elected in its original certificate of incorporation
       not to be governed by Section 203. We did not make this election;
 
     - the business combination was approved by the board of directors of the
       corporation before the other party to the business combination became an
       interested stockholder;
 
     - upon consummation of the transaction that made it an interested
       stockholder, the interested stockholder owned at least 85% of the voting
       stock of the corporation outstanding at the commencement of the
       transaction, excluding voting stock owned by directors who are also
       officers or held in employee benefit plans in which the employees do not
       have a confidential right to tender or vote stock held by the plan; or
 
     - the business combination was approved by the board of directors of the
       corporation and ratified by two-thirds of the voting stock not owned by
       the interested stockholder.
 
     The three-year prohibition also does not apply to some business
combinations proposed by an interested stockholder following the announcement or
notification of an extraordinary transaction involving the corporation and a
person who had not been an interested stockholder during the previous three
years or who became an interested stockholder with the approval of the majority
of the corporation's directors.
 
     The term "business combination" is defined generally under Section 203 to
include mergers or consolidations between a Delaware corporation and an
interested stockholder, transactions with an interested stockholder involving
the assets or stock of the corporation or its majority-owned subsidiaries and
transactions which increase an interested stockholder's percentage ownership of
stock. The term "interested stockholder" is defined generally under Section 203
as a stockholder who, together with affiliates and associates, owns or within
three years prior did own 15% or more of a Delaware corporation's voting stock.
Section 203 could prohibit or delay a merger, takeover or other change in
control of us and therefore could discourage attempts to acquire us.
 
     Our Board approved both the acquisition of common stock by WEB as part of
their approval of WEB Hosting Organization Investment and the acquisition of
preferred stock and warrants by the SOFTBANK

Purchasers as part of their approval of the SOFTBANK Investment and,

combination with either WEB or the SOFTBANK Purchasers.

SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Immediately following this offering, there will be 41,663,045 shares of our
common stock issued and outstanding assuming that no option holder exercises any
outstanding stock options after April 29, 1999. Of these shares, the 7,000,000
shares of common stock to be sold in this offering will be immediately eligible
for sale in the public market. Of the remaining 34,663,045 issued and
outstanding shares 34,621,085 will be restricted securities within the meaning
of Rule 144 and may not be publicly resold, except in compliance with the
registration requirements of the Securities Act pursuant to an exemption from
registration, including that provided by Rule 144. All of the restricted shares
are subject to the 180-day lock-up agreements described below.
    
 
RULE 144
 
     In general, under Rule 144, a person, or persons whose shares are
aggregated, who has beneficially owned restricted securities for at least one
year, including a person who may be deemed an affiliate, is entitled to sell
within any three month period a number of our shares of common stock that does
not exceed the greater of:
 
     - 1% of the then-outstanding shares of our common stock; or
 
     - the average weekly trading volume of our common stock on the NASDAQ
       National Market during the four calendar weeks preceding the date on
       which notice of sale is filed with the Securities and Exchange
       Commission.
 
Sales under Rule 144 are subject to restrictions relating to manner of sale,
notice and the availability of current public information about us. Commencing
90 days after the date of this prospectus, 3,150,000 shares of common stock will
be eligible for resale under Rule 144. All of such shares are subject to the
180-day Lock-up Agreements described below.
 
     A person who is not deemed an affiliate of ours at any time during the 90
days preceding a sale and who has beneficially owned shares for at least two
years would be entitled to sell shares following this offering under Rule 144(k)
without regard to the volume limitations, manner of sale provisions or notice
requirements of Rule 144.
 
RULE 701
 
     Our employees, directors, officers or consultants who purchase our shares
in connection with a written compensatory plan or contract may be entitled to
rely on the resale provisions of Rule 701. Rule 701 permits non-affiliates to
sell their Rule 701 shares without having to comply with the public information,
holding period, volume limitation or notice provisions of Rule 144. Affiliates
may sell their Rule 701 shares without having to comply with Rule 144's holding
period restrictions. In each of these cases Rule 701 allows the shareholders to
sell 90 days after the date of this prospectus.
 
OPTIONS
 
     We intend to file one or more registration statements on Form S-8 under the
Securities Act to register all shares of Common Stock subject to outstanding
stock options and Common Stock issuable
                                       74
<PAGE>   80
 
pursuant to our stock option plans. Shares covered by these registration
statements will thereupon be eligible for sale in the public markets, subject to
the 180-day Lock-up Agreements described below, to the extent applicable.
 
LOCK-UP AGREEMENTS
 
     For a period of 180 days after the date of this prospectus, we, our
executive officers, directors and substantially all of our stockholders, have
agreed not to, without approval by Merrill Lynch:
 
     - sell, dispose of or transfer any shares of common stock or securities
       convertible into common stock;
 
     - enter into any agreement that transfers any part of the economic
       consequence of ownership of the common stock; or
 
     - seek or exercise any right to register any share of common stock or
       security convertible into common stock.
 
     Our stockholders do, however, have the right to:
 
     - transfer the securities as a gift, if the recipient agrees to be bound by
       the provisions of the lock-up agreement; or
 
     - pledge their securities to us in consideration for a loan from us.
 
     In addition, we do have the right to transfer common stock in connection
with an acquisition, if any recipient of such shares agrees to be bound by the
provisions of the lock-up agreement.
 
EFFECT OF SALES OF SHARES
 
     No prediction can be made as to the effect, if any, that future sales of
shares of common stock or the availability of shares for future sale will have
on the prevailing market price for the common stock. Sales of substantial
amounts of common stock, or the perception that such sales could occur, could
adversely affect prevailing market prices for the common stock and could impair
our future ability to raise capital through an offering of equity securities.

     We have also entered into an international purchase agreement with certain
international managers outside the United States and Canada for whom Merrill
Lynch International, Donaldson, Lufkin & Jenrette International and CIBC World
Markets International Limited are acting as lead managers. Subject to the terms
and conditions set forth in the international purchase agreement, and
concurrently with the sale of 6,125,000 shares of common stock to the U.S.
underwriters pursuant to the U.S. purchase agreement, we have agreed to sell to
the international managers and the international managers severally have agreed
to purchase from us an aggregate of 875,000 shares of common stock. The initial
public offering price per share and the total underwriting discount per share of
common stock are identical under the U.S. purchase agreement and the
international purchase agreement.
 
     In the U.S. purchase agreement and the international purchase agreement,
the several U.S. underwriters and the several international underwriters have
agreed, subject to the terms and conditions set forth therein, to purchase all
of the shares of common stock being sold pursuant to each such agreement if any
of the shares of common stock being sold pursuant to such agreement are
purchased. In the event of a default by an underwriter, the U.S. purchase
agreement and the international purchase agreement provide that, in certain
circumstances, the purchase commitments of the nondefaulting underwriters may be
increased or the purchase agreements may be terminated. The closings with
respect to the sale of shares of common stock to be purchased by the U.S.
underwriters and the international managers are conditioned upon one another.
 
     We have agreed to indemnify the U.S. underwriters and the international
managers against some liabilities, including some liabilities under the
Securities Act, or to contribute to payments the U.S. underwriters and the
international managers may be required to make in respect of those liabilities.
 
     The shares of common stock are being offered by the several underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to approval of certain legal matters by counsel for the underwriters and certain
other conditions. The underwriters reserve the right to withdraw, cancel or
modify such offer and reject orders in whole or in part.

COMMISSIONS AND DISCOUNTS
 
     The U.S. representatives have advised us that the U.S. underwriters propose
initially to offer the shares of common stock to the public at the initial
public offering price set forth on the cover page of this prospectus, and to
certain dealers at such price less a concession not in excess of $     per share
of common stock. The U.S. underwriters may allow, and such dealers may reallow,
a discount not in excess of $     per share of common stock to certain other
dealers. After the initial public offering, the public offering price,
concession and discount may change.
 
     The following table shows the per share and total public offering price,
underwriting discount to be paid by us to the U.S. underwriters and the
international managers and the proceeds before expenses to us. This information
is presented assuming either no exercise or full exercise by the U.S.
underwriters and the international managers of their over-allotment options.

     The expenses of the offerings (exclusive of the underwriting discount and
commissions) are estimated at $1.4 million and are payable by us.
 
INTERSYNDICATE AGREEMENT
 
     The U.S. underwriters and the international managers have entered into an
intersyndicate agreement that provides for the coordination of their activities.
Under the terms of the intersyndicate agreement, the U.S. underwriters and the
international managers are permitted to sell shares of our common stock to each
other for purposes of resale at the initial public offering price, less an
amount not greater than the selling concession. Under the terms of the
intersyndicate agreement, the U.S. underwriters and any dealer to whom they sell
shares of our common stock will not offer to sell or sell shares of our common
stock to persons who are non-U.S. or non-Canadian persons or to persons they
believe intend to resell to persons who are non-U.S. or non-Canadian persons,
and the international managers and any dealer to whom they sell shares of common
stock will not offer to sell or sell shares of common stock to U.S. persons or
to Canadian persons or to persons they believe intend to resell to U.S. or
Canadian persons, except in the case of transactions under the terms of the
intersyndicate agreement.
 
OVER-ALLOTMENT OPTION
 
     We have granted options to the U.S. underwriters, exercisable for 30 days
after the date of this prospectus, to purchase up to an aggregate of 920,000
additional shares of common stock at the public offering price set forth on the
cover page of this prospectus, less the underwriting discount. The U.S.
underwriters may exercise this option solely to cover over-allotments, if any,
made on the sale of the common stock offered hereby. To the extent that the U.S.
underwriters exercise this option, each U.S. underwriter will be obligated,
subject to certain conditions, to purchase a number of additional shares of
common stock proportionate to such U.S. underwriter's initial amount reflected
in the foregoing table.
 
     We also have granted an option to the international managers, exercisable
for 30 days after the date of this prospectus, to purchase up to an aggregate of
130,000 additional shares of common stock to cover over-allotments, if any, on
terms similar to those granted to the U.S. underwriters.
 
     The shares of common stock are being offered by the several underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to approval of certain legal matters by counsel for the underwriters and certain
other conditions. The underwriters reserve the right to withdraw, cancel or
modify such offer and to reject orders in whole or in part.

RESERVED SHARES
 
     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to 350,000 shares, or 5%, of the shares offered
hereby, to be sold to some of our directors, officers, employees, distributors,
dealers, business associates and related persons. The number of shares of common
stock available for sale to the general public will be reduced to the extent
those persons purchase such reserved shares. Any reserved shares which are not
orally confirmed for purchase within one day of the pricing of this offering
will be offered by the underwriters to the general public on the same terms as
the other shares offered in this prospectus.
 
NO SALES OF SIMILAR SECURITIES
 
     For a period of 180 days after the date of this prospectus, we, our
executive officers, directors and substantially all of our stockholders, have
agreed not to directly or indirectly, without approval by Merrill Lynch on
behalf of the underwriters:
 
     - Offer, pledge, sell, dispose of or transfer any shares of common stock or
       securities convertible into common stock;
 
     - Enter into any agreement that transfers any part of the economic
       consequence of ownership of the common stock; or
 
     - Seek or exercise any right to register any share of common stock or
       security convertible into common stock.
 
     Our stockholders do, however, have the right to:
 
     - Transfer the securities as a gift, if the recipient agrees to be bound by
       the provisions of the lock-up agreement; or
 
     - Pledge their securities to us in consideration for a loan from us.
 
     In addition, we have the right to transfer common stock in connection with
an acquisition, if any recipient of such shares agrees to be bound by the
provisions of the lock-up agreement.
 
QUOTATION ON THE NASDAQ NATIONAL MARKET
 
     Our common stock has been approved for quotation on the Nasdaq National
Market, subject to official notice of issuance, under the symbol "INIT."
 
     Before this offering, there has been no public market for our common stock.
The initial public offering price will be determined through negotiations
between us and the U.S. representatives and the lead managers. The factors to be
considered in determining the initial public offering price, in addition to
prevailing market conditions, are expected to be the valuation multiples of
publicly traded companies that the U.S. representatives and the lead managers
believe to be comparable to us, certain of our financial information, the
history of, and the prospects for, our company and the industry in which we
compete, and an assessment of our management, its past and present operations,
the prospects for, and timing of, our future revenues, the present state of our
development and the above factors in relation to market values and various value
measures of other companies engaged in activities similar to ours. There can be
no assurance that an active trading market will develop for our common stock or
that our common stock will trade in the public market subsequent to this
offering at or above the initial public offering price.
 
     The underwriters do not expect sales of the common stock to be made to any
accounts over which they exercise discretionary authority to exceed 5% of the
number of shares being offered in this offering.
 
PRICE STABILIZATION, SHORT POSITIONS AND PENALTY BIDS
 
     Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters and
certain selling group members to bid for and
 
                                       78
<PAGE>   84
 
purchase our common stock. As an exception to these rules, the U.S.
representatives are permitted to engage in certain transactions that stabilize
the price of our common stock. Such transactions consist of bids or purchases
for the purpose of pegging, fixing or maintaining the price of our common stock.
 
     If the underwriters create a short position in our common stock in
connection with the offering contemplated hereby, i.e., if they sell more shares
of our common stock than are set forth on the cover page of this prospectus, the
U.S. representatives may reduce that short position by purchasing our common
stock in the open market. The U.S. representatives may also elect to reduce any
short position by exercising all or part of the over-allotment option described
above.
 
     The U.S. representatives may also impose a penalty bid on our underwriters
and selling group members. This means that if the U.S. representatives purchase
shares of our common stock in the open market to reduce the underwriters' short
position or to stabilize the price of the our common stock, they may reclaim the
amount of the selling concession from the underwriters and selling group members
who sold those shares.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of our common stock to the extent that it
discourages resales of our common stock.
 
     Neither we nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of our common stock. In addition, neither
we nor any of the underwriters makes any representation that the U.S.
representatives will engage in such transactions or that such transactions, once
commenced, will not be discontinued.
 
                                 LEGAL MATTERS
 
     The validity of the shares of common stock offered hereby will be passed
upon for us by Dewey Ballantine LLP, New York, New York. Certain legal matters
in connection with the offering will be passed upon for the underwriters by
Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo Alto,
California.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
   
Interliant, Inc. (formerly known as Sage Networks, Inc.)
    
 
   
     We have audited the accompanying consolidated balance sheets of Interliant,
Inc. (formerly known as Sage Networks, Inc.) (the Company) as of December 31,
1997 and 1998, and the related consolidated statements of operations,
stockholders' equity, and cash flows for the period December 8, 1997 (inception)
to December 31, 1997 and the year ended December 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
    
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
   
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Interliant, Inc. (formerly known as Sage Networks, Inc.) at December 31, 1997
and 1998, and the consolidated results of its operations and its cash flows for
the period December 8, 1997 (inception) to December 31, 1997 and the year ended
December 31, 1998, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE PERIOD FROM DECEMBER 8, 1997 (INCEPTION) TO DECEMBER 31, 1997, THE YEAR
 ENDED DECEMBER 31, 1998 AND THE THREE MONTHS ENDED MARCH 31, 1999 (UNAUDITED)
 
1. BUSINESS
 
     Sage Networks, Inc. (the Company) was organized under the laws of the State
of Delaware on December 8, 1997. Web Hosting Organization LLC (WEB), a Delaware
Limited Liability Company, is the majority and controlling shareholder of the
Company. WEB's investors are comprised of Charterhouse Equity Partners III, L.P.
and Chef Nominees Limited (collectively, CEP Members) and WHO Management, LLC
(WHO). As of December 31, 1998, CEP Members have invested $29,000,000, and WHO
has invested $2,000,000 in WEB. WEB has, in turn, invested $31,000,000 in the
Company. CEP Members have allocated an additional $11,000,000 to invest in WEB,
and have funded the remaining amount pursuant to a stock subscription agreement
(see Notes 7 and 12).
 
     Since its formation, the Company has been in the process of developing a
Web hosting business. The Company continues to build its Web hosting business
primarily through the acquisition of the Web hosting assets of Internet service
providers, system integrators and Web hosting companies. The primary sources of
revenue are from recurring fees charged to customers for hosting their Web sites
on the Company's server systems. The Company focuses on delivering high-quality,
reliable and flexible Web hosting services.
 
     Prior to 1998, the Company was in the development stage.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated.
 
  Unaudited Interim Financial Information
 
     The interim financial information as of March 31, 1999 and for the three
months ended March 31, 1998 and 1999 is unaudited and has been prepared on the
same basis as the audited financial statements. In the opinion of management,
such unaudited information includes all adjustments (consisting only of normal
recurring adjustments) necessary for a fair presentation of the interim
information. Operating results for the three months ended March 31, 1998 and
1999 are not necessarily indicative of the results that may be expected for the
year ending December 31, 1999.
 
  Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity (at date of purchase) of three months or less to be the
equivalent of cash for the purpose of balance sheet and statement of cash flows
presentation. Cash equivalents, which consist primarily of money market
accounts, are carried at cost, which approximates market value.
 
  Fair Value of Financial Instruments
 
     Carrying amounts of financial instruments held by the Company, which
include cash equivalents, accounts receivable, accounts payable and accrued
expenses, approximate fair value due to their short duration.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Concentrations of Credit Risk
 
     Financial instruments that potentially subject the Company to
concentrations of credit risk are comprised principally of cash, cash
equivalents and accounts receivable. As of December 31, 1998, the Company's cash
and cash equivalents are deposited with various domestic financial institutions.
With respect to accounts receivable, the Company's customer base is dispersed
across many geographic areas. The Company monitors customer payment history,
generally does not require collateral and establishes reserves for uncollectible
accounts as warranted. In addition to individual customers, the Company also
provides Web hosting services to resellers, who, in turn, provide services to
their own customers.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent liabilities, at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
  Furniture, Fixtures and Equipment
 
     Furniture, fixtures and equipment are stated at cost. Major additions and
betterments are capitalized, while replacements, maintenance and repairs that do
not improve or extend the life of the assets are charged to expense.
Depreciation has been provided using the straight-line method over the estimated
useful lives of the assets as follows:
 
<TABLE>
<S>                                         <C>
Network software and equipment............  3 years
Furniture, fixtures and office
  equipment...............................  3 years
Leasehold improvements....................  Lesser of remaining lease-term or useful
                                            life
</TABLE>
 
  Internally Developed Software
 
     In 1998, the Company adopted Statement of Position 98-1, Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use (SOP 98-1)
issued by the American Institute of Certified Public Accountants. SOP 98-1
permits the capitalization of certain internally developed costs related to the
development of internally used software. During 1998, the Company capitalized
approximately $650,000 of project costs related to software developed
internally.
 
  Intangible Assets
 
     Intangible assets consist primarily of customer lists, covenants not to
compete, other identifiable intangibles and goodwill, which arose from the
acquisitions of several Web hosting companies and are being amortized on a
straight-line basis over periods ranging from one to ten years (see Note 4).
 
  Impairment of Long-Lived Assets
 
   
     The Company continually reviews amortization periods and the carrying value
of long-lived assets, including furniture, fixtures and equipment, and
intangible assets to determine whether there are any indications of reduction in
useful lives or impairment losses. If indications of impairment are present in
long-lived assets, the estimated future undiscounted cash flows associated with
the corresponding assets would be compared to its carrying amount to determine
if a change in useful life or a write-down to fair value is necessary.

  Revenue Recognition
    
 
   
     Through December 31, 1998 revenues consisted of Web hosting services and
set-up fees. As a result of acquisitions in February and March 1999 (see Note
12) the Company began earning revenues from application hosting and related one
time implementation fees and consulting services.
    
 
   
     The Company generally sells its Web hosting services for contractual
periods ranging from one to twelve months. Revenues from these services are
recognized ratably over the contractual period. Payments received and billings
in advance of providing services are deferred until the period such services are
provided. Set-up fees, which cover costs incurred by the Company to establish a
customer's Web site and are non-refundable, are recognized when the set-up
services are performed and the Company has no further obligation with respect to
such set-up fees. Incremental fees for excess bandwidth and storage usage are
billed and recorded as revenues as customers utilize such services. To date,
such fees have been de minimus.
    
 
   
     Application hosting revenues are comprised of monthly usage fees per number
of end users, including bandwidth fees and one-time implementation fees, all of
which are recorded as revenue at the time the services are used by the customer.
One time implementation fees which cover costs incurred by the Company to
establish a customer's site and are nonrefundable, are recognized when the site
is established and the Company has no further obligation with respect to such
fees. To date such fees have been de minimus.
    
 
   
     Revenues from consulting services are recognized as the services are
rendered, provided that no significant obligations remain and collection of the
receivable is considered probable. Generally, contracts call for billings on a
time and materials basis; however, in instances when a fixed fee contract is
signed, revenue is recognized on a percentage-of-completion basis.
    
 
   
  Advertising Expenses
    
 
     All advertising costs are expensed as incurred. Advertising expenses for
the year ended December 31, 1998 amounted to $672,000. No advertising costs were
incurred in the period December 8, 1997 (inception) through December 31, 1997.
 
  Start-Up and Acquisition Integration Costs
 
   
     In connection with acquisitions made by the Company during the year ended
December 31, 1998 (see Note 5), the Company incurred payroll, consulting and
travel costs to start-up and integrate the acquisitions into the Company.
    
 
  Income Taxes
 
     The Company accounts for income taxes using the liability method under
which 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.
 
  Net Loss Per Share
 
     Net loss per share is presented in accordance with the provisions of
Statement of Financial Accounting Standards No. 128, Earnings Per Share. Basic
net loss per share is computed based on the weighted average number of shares of
common stock outstanding. Diluted loss per share does not differ from basic loss
per share since potential common shares to be issued upon exercise of stock
options are anti-dilutive for the periods presented.

7. STOCKHOLDERS' EQUITY
 
  Common Stock
 
     Pursuant to a Stock Subscription Agreement dated December 8, 1997 between
the Company and WEB, WEB purchased 15,600,000 shares of the Company's Common
Stock during the year ended December 31, 1998 and 3,000,000 shares during the
period December 8, 1997 (inception) to December 31, 1997, all at $1.67 per
share. WEB is entitled to purchase an additional 6,600,000 shares at $1.67
pursuant to the Stock Subscription Agreement (see Note 12).
 
     The Board of Directors approved a three-for-one stock split of the
Company's Common Stock on July 28, 1998. The accompanying financial statements
have been retroactively restated to give effect to the stock split.
 
  Stock Option Plan
 
     On February 1, 1998, the Company adopted the Sage Networks, Inc. 1998 Stock
Option Plan (the Plan), which is administered by the Board of Directors (the
Committee). Under the terms of the Plan, the Committee may grant stock options
to officers, employees and consultants of the Company. The Plan permits the
grant of incentive stock options (ISOs) and nonqualified stock options (NSOs).
As of December 31, 1998, the Company has reserved 1,500,000 shares of Common
Stock for issuance under the Plan. Stock options may not be granted at less than
100% of the fair market value of the Common Stock on the date of the grant and
may not expire more than ten years from the date of the grant. Options granted
under the Plan generally will become exercisable over a four-year period in
equal annual

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
installments unless the Committee specifies a different vesting schedule. In the
event of a change in control of the Company, each option becomes immediately
vested and exercisable, provided that no written provision has been made, in
connection with any such event, for (1) the continuation of the stock option
plan and/or the assumption of all outstanding options by a successor corporation
or (2) the substitution for such options of new options covering the stock of a
successor corporation. The Plan has a term of ten years, subject to earlier
termination or amendment by the Committee, and all options under the Plan prior
to its termination remain outstanding until they have been exercised or
terminated.
 
     During the year ended December 31, 1998, the Company granted 440,500
options at prices ranging from $1.67 to $6.67 per share. The weighted-average
exercise price of the options granted was $4.11. No options were exercised,
canceled or forfeited during the year ended December 31, 1998. No options are
vested at December 31, 1998.
 
  Stock-Based Compensation
 
     As discussed in Note 2, the Company applies APB 25 and related
interpretations in accounting for its stock option plan. Accordingly, since the
Company grants stock options with exercise prices at least equal to fair value
at the date of grant, no compensation expense has been recognized relating to
option grants in 1998.
 
     As required under FAS 123, the following pro forma net loss and net loss
per share presentations reflect the amortization of the option grant fair value
as expense. For purposes of this disclosure, the estimated fair value of the
options is amortized to expense over the options' vesting periods. The Company's
pro forma information follows for the year ended December 31, 1998:
 
<TABLE>
<S>                                                           <C>
Pro forma net loss..........................................  $(9,756,000)
Pro forma net loss per share -- basic and diluted...........  $     (1.11)
</TABLE>
 
     The weighted average grant date value was $0.83 for stock options issued in
1998, and the weighted-average remaining contractual life for options
outstanding as of December 31, 1998 is 9.4 years. Significant assumptions used
in determining this value include a risk free interest rate of 5.6%, expected
life of the options of four years, and a dividend rate of zero.
 
     The effects on pro forma disclosures of applying SFAS 123 are not likely to
be representative of the effects on pro forma disclosures in future years as the
period presented includes only one year of option grants under the Plan.
 
8. INCOME TAXES
 
     As of December 31, 1998, the Company has federal and state net operating
loss carryforwards of approximately $7,700,000. The net operating loss
carryforwards will expire at various dates beginning in the years 2003 through
2018 if not utilized.
 
     Significant components of the Company's deferred tax assets and liabilities
for federal and state income taxes consist of the following at December 31,
1998:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company believes that, based on a number of factors, the available
objective evidence creates sufficient uncertainty regarding the realization of
the deferred tax assets such that a full valuation allowance has been recorded.
The Company will continue to assess the realization of the deferred tax assets
based on actual and forecasted operating results.
 
9. LEASES
 
     The Company leases its data centers and certain office space under
noncancelable operating leases, which expire at various dates through June 2009.
Some of the leases contain renewal options. Total rent expense for all operating
leases was approximately $7,000 and $420,000 for the period December 8, 1997
(inception) to December 31, 1997 and the year ended December 31, 1998,
respectively. In connection with one of the leases, the Company has given the
landlord a standby letter of credit in the amount of approximately $100,000 in
lieu of a security deposit.
 
     Future minimum lease commitments for noncancelable operating leases are as
follows at December 31, 1998:

10. RELATED-PARTY TRANSACTIONS
 
     In connection with the acquisitions of certain Web hosting assets of
various entities (see Note 5), the Company paid or accrued transaction fees of
approximately $319,000 to Charterhouse Group International, Inc., a related
party of WEB. These fees are included in the respective purchase price
allocations as capitalized transaction costs.
 
   
     The Company receives consulting services from Sage Equities, Inc. and
Intensity Ventures, Inc., whose principals are the co-chairmen of the Company
and members of WHO, for the purpose of identifying and executing potential
acquisitions. Sage Equities, Inc. and Intensity Ventures, Inc. are each paid
fees of $10,000 (plus expenses) per month for such services. For the period
December 8, 1997 (inception) to December 31, 1997 and the year ended December
31, 1998, the Company incurred costs under these agreements of $25,000 and
$120,000, respectively, for Sage Equities, Inc., and $17,000 and $232,000 (of
which $112,000 were expenses), respectively, for Intensity Ventures. At December
31, 1997, these entities were owed a total of $84,959 by the Company for such
consulting services, which was paid in 1998.
    
 
     The Company also receives consulting services from one other member of WHO.
During the period December 8, 1997 (inception) to December 31, 1997 and the year
ended December 31, 1998, the Company incurred costs relating to these services
totaling approximately $8,000 and $44,000, respectively.
 
11. EMPLOYEE BENEFIT PLAN
 
     In 1998, the Company instituted a 401k Plan for all employees who have
attained age 21 and have been employed by the Company or by an acquired business
for one month. Participating employees may make contributions to the plan up to
15% of their compensation. The Plan provides that the Company may

make discretionary contributions to the Plan on behalf of participating
employees. The Company did not make any such contributions for the year ended
December 31, 1998.
 
12. SUBSEQUENT EVENTS
 
     On January 28, 1999, the Company's Board of Directors and Stockholders
approved an amendment to the Company's certificate of incorporation (Charter) to
increase the number of authorized shares to 35,000,000 shares of Common Stock
and up to 2,647,658 shares of Preferred Stock, all of which is designated as
Series A Convertible Preferred Stock (Series A Preferred).
 
     On January 28, 1999, pursuant to a Securities Purchase Agreement (the
Purchase Agreement) the Company sold to Softbank Technology Ventures IV L.P. and
one of its affiliates (the Series A Investors), 2,647,658 shares of its Series A
Preferred at a price of $4.91 per Series A Preferred share and issued 749,625
Common Stock warrants of the Company for cash of $13,000,000. The Series A
Preferred is convertible at any time, at the option of the holder, into the
Company's Common Stock, subject to anti-dilution provisions as set forth in the
Charter. In the event of a qualifying public offering (as defined in the
Charter), however, the Series A Preferred is automatically converted into Common
Stock. If the Series A Preferred is not converted before January 28, 2006, a
majority in interest of the holders thereof may request the Company to redeem
the Series A Preferred at $4.91 per share plus any accrued but unpaid dividends
on such shares. Because of the redemption features of the Series A Preferred, it
will not be reported as a component of stockholders' equity. The warrants are
immediately exercisable at a price of $6.67 per share. The warrants expire on
the earlier of three years subsequent to the consummation of the Company's
initial public offering or January 28, 2003. The Company, the Series A Investors
and WEB have entered into an Investors Agreement dated January 28, 1999, which
provides the Series A Investors to nominate a director to the Company's Board of
Directors and grants the Series A Investors preemptive rights and certain
registration rights.
 
     On February 9, 1999, pursuant to its stock subscription agreement, WEB
purchased the remaining 6,600,000 shares of the Company's Common Stock for an
aggregate of $11,000,000 (see Note 7).
 
     The Company consummated the following acquisitions in the early part of
February 1999, each of which will be accounted for using the purchase method of
accounting:
 
          The purchase of certain assets of Telephonetics International, Inc., a
     provider of customized music and messages on hold recording services to
     businesses utilizing on-hold telephone equipment. The purchase price
     consists of cash of $3,000,000 and 140,000 shares of the Company's Common
     Stock valued at $6.67 per share.
 
          The purchase of all of the outstanding stock of Net Daemons
     Associates, Inc. (NDA), a provider of Web development and system
     integration activity for Internet and IP Networks. The purchase price
     consists of cash of $500,000 and 425,000 shares of the Company's Common
     Stock valued at $6.67 per share. In addition, the Company has agreed to pay
     certain officers of NDA $2,371,000 to induce them to enter into non-compete
     agreements and to pay approximately $436,000 to cancel certain NDA stock
     options. The agreement also provides for contingent purchase consideration
     of $500,000 in cash and 74,963 shares of the Company's Common Stock if
     specified gross revenue and gross margin targets are achieved in the
     twelve-month period following the acquisition. The payment of contingent
     consideration, if any, will be recorded as additional purchase price. The
     shares of stock and cash to be paid for the contingent purchase
     consideration have been deposited with an escrow agent.
 
          The purchase of the Web hosting assets of Digiweb, Inc., a Web hosting
     company. The purchase price consists of cash of approximately $5,000,000
     and 450,000 shares of the Company's Common

     Stock valued at $6.67. The agreement provides for contingent purchase
     consideration of $1,000,000 if specified revenue and earnings targets are
     achieved in the year ending December 31, 1999. The payment of contingent
     consideration, if any, will be recorded as additional purchase price.
 
     In March 1999, the Company's stockholders approved an amendment to the
Company's certificate of incorporation to increase the number of authorized
shares of Common Stock to 100,000,000, and, on March 10, 1999, the Company
acquired substantially all of the assets and assumed specified liabilities of
Interliant, Inc., a provider of groupware hosting and application outsourcing
services. The purchase price consisted of $100,000 in cash and 4,091,642 shares
of the Company's Common Stock valued at $6.67 per share, and options to purchase
up to 2,322,179 shares of the Company's Common Stock. In addition, the Company
paid $7,900,000 on an outstanding note payable of Interliant, Inc. at closing
and will pay the balance of the note ($8,000,000) at the earlier of the
completion of an initial public offering of the Company's Common Stock or
September 1999. The transaction will be accounted for using the purchase method
of accounting. In connection with this acquisition, the Company changed its name
to Interliant, Inc.
 
     The purchase consideration for the acquisitions referred to above is as

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
     During the period from inception through March 10, 1999, Interliant, Inc.
(formerly, Sage Networks, Inc.) ("Interliant" or the "Company") completed
numerous business combinations, whereby the Company acquired shares of common
stock, or certain net assets of entities operating in the Internet industry.
Business combinations are accounted for using the purchase method of accounting.
 
     The unaudited pro forma consolidated statement of operations for the year
ended December 31, 1998 and the three months ended March 31, 1999 assumes that
the acquisitions completed in 1998 and 1999 had occurred on January 1, 1998, and
includes the historical consolidated statements of operations of Interliant,
adjusted for the pro forma effects of the acquisitions.
 
     The unaudited pro forma consolidated statement of operations is not
necessarily indicative of the results of operations that would actually have
occurred if the transactions had been consummated as of January 1, 1998 and is
not intended to indicate the expected results for any future period. These
statements should be read in conjunction with the historical consolidated
financial statements and related notes thereto of Interliant, and of certain
acquired businesses, included elsewhere in this prospectus.
 
     The unaudited pro forma adjustments are based upon preliminary estimates
and certain assumptions that management of Interliant believes are reasonable in
the circumstances. The actual adjustments may be revised upon completion of the
purchase price allocations. Except for additions to intangible assets on
contingent purchase price payments based on the underlying purchase agreements,
management of Interliant does not believe that actual adjustments will be
materially different from preliminary estimates.

assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1. SIGNIFICANT ACCOUNTING POLICIES
 
 Nature of business
 
     Clever Computers, Inc. was incorporated October 25, 1993 in the State of
Georgia. The Company is engaged in the business of Internet Web hosting.
 
  Property and equipment
 
     Property and equipment are recorded at cost. Depreciation is provided over
the estimated useful lives of the assets by accelerated and straight line
methods.
 
  Statement of cash flows
 
     The Company considers instruments with a maturity of three months or less
to be cash equivalents for purposes of the statement of cash flows.
 
  Income taxes
 
     Income taxes are accounted for in accordance with provisions of Statement
of Financial Accounting Standards No. 109. Deferred income taxes have been
provided for the difference in bad debt expense for income tax and financial
statement reporting purposes.
 
  Organization costs
 
     Organization costs are being amortized on a straight line basis over five
years.
 
  Deferred revenues
 
     As part of their standard service agreements with customers, the Company
bills for all services for three months in advance. As a result, a portion of
revenues collected and billed for as of year end relates to services not yet
performed. The deferred revenue associated with these services is recognized on
the balance sheet as a current liability.
 
  Estimates
 
     Management uses estimates and assumptions in preparing financial
statements. Those estimates and assumptions affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities, and
the reported revenues and expenses. Actual results could differ from those
estimates.
 
NOTE 2. LEASES
 
     The Company leases office facilities and certain equipment. Renewal options
are available on some of these leases.
 
     Future minimum lease payments required on noncancelable operating leases
having initial or remaining terms in excess of one year as of December 31, 1997,
are as follows:

                          INDEPENDENT AUDITOR'S REPORT
 
To the Board of Directors
Sage Networks, Inc.
 
     We have audited the accompanying balance sheets of Tri Star Web Creations,
Inc. as of December 31, 1996 and 1997, and the related statements of operations,
and changes in retained earnings, and cash flows for the years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free from
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 Tri Star Web Creations, Inc.
as of December 31, 1996 and 1997, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting
principles.

                               DECEMBER 31, 1997
 
NOTE 1. DESCRIPTION OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
 
     Description of Operations:  Tri Star Web Creations, Inc. (the "Company") is
primarily engaged in the business of providing web hosting services for
companies and individuals nationwide placing websites on the Internet.
 
  Summary of Significant Accounting Policies
 
     Revenue Recognition:  The Company recognizes service revenues ratably as
hosting services are provided.
 
     Concentrations of Credit Risk:  The Company extends credit based on an
evaluation of the customer's financial condition, generally without requiring
collateral. Exposure to losses on receivables is principally dependent on each
customer's financial condition. The Company monitors its exposure for credit
losses and maintains allowances for anticipated losses.
 
     Fixed Assets:  Fixed assets are carried at cost, less accumulated
depreciation. Depreciation is computed using the straight-line method over the
estimated useful lives of the related assets which range from five to seven
years.
 
     Income Taxes:  The Company, with the consent of its stockholders, has
elected to be taxed under sections of the federal and state income tax laws
which provide that, in lieu of corporation income taxes, the stockholder
separately accounts for the Company's items of income, deduction, losses and
credits. Therefore, no provision or liability for Federal tax is reflected in
the financial statements. A provision for state taxes is included in operating
expenses.
 
     Use of Estimates in the Preparation of Financial Statements:  The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the dates of the financial statements and
the reported amounts of revenues and expenses during the reporting periods.
Actual results could differ from those estimates.
 
NOTE 2. FIXED ASSETS
 
     Fixed assets consist of the following at December 31:

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
HomeCom Communications, Inc.
 
     In our opinion, the accompanying statements of assets and liabilities and
the related statements of revenues and expenses and of cash flows present
fairly, in all material respects, the financial position of HostAmerica, a
division of HomeCom Communications, Inc., at December 31, 1996 and 1997, and the
results of its operations and its cash flows for the three years in the period
ended December 31, 1997, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.
 
     The accompanying financial statements have been carved out of the
historical financial statements of HomeCom Communications, Inc. As such, these
financial statements represent a lesser business component and are not intended
to be a complete presentation of the financial position or the results of
operations or cash flows of the Company were it to operate on a stand-alone
basis. A description of the significant assumptions used to prepare the
carve-out financial statements is included in Note 1 to the financial
statements.
 
     As discussed in Note 1 to the financial statements, substantially all the
assets of HostAmerica were sold to Sage Acquisition Corp. on June 9, 1998.

                         NOTES TO FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Business
 
     HostAmerica is a trade name of HomeCom Communications, Inc. ("HomeCom")
under which HomeCom provides full service Internet Web site hosting services.
The Web hosting operations of HomeCom conducted under the HostAmerica trade name
are herein referred to as "HostAmerica" or "the Division".
 
     On June 9, 1998, HomeCom sold certain assets of the Division, consisting
principally of hosting contracts, equipment and the trade name "HostAmerica" to
Sage Acquisition Corp. for $4,500,000. Pursuant to the terms of the Asset
Purchase Agreement (the "Agreement"), HomeCom retained all of the accounts
receivable of HostAmerica existing as of May 31, 1998, and retained certain
hosting contracts, and the right to perform hosting services in the future for
companies in the financial services industry. The Agreement required the deposit
of $250,000 of the proceeds to be held in escrow until May 1, 1999, for the
purpose of indemnifying Sage Acquisition Corp. for representations and
warranties made by HomeCom under the Agreement.
 
  Basis of Presentation
 
     Historically, financial statements were not prepared for the Division. The
accompanying financial statements have been prepared in accordance with
generally accepted accounting principles and have been "carved out" of the
financial statements of HomeCom for each of the periods, and as of each of the
dates presented. As such, these statements represent a lesser business component
and are not intended to be a complete presentation of the financial position or
the results of operations or cash flows of the Division were it to operate on a
stand-alone basis.
 
     The accompanying financial statements exclude the assets, liabilities and
revenues related to certain premium hosting accounts referred to as Excluded
Customers in the Agreement. The statements of revenues and expenses of the
Division include all revenues and costs directly attributable to the Division
and also include allocations of corporate overhead from HomeCom. Expenses have
been allocated based on a variety of methods depending on the nature of the
expense. Such allocation methods include proportional HostAmerica revenues to
total HomeCom revenues, headcount equivalents and management estimates. The cost
of providing hosting services represents direct payroll and related costs of
those employees involved in providing hosting services and an allocation of
Internet connection services. An allocation of corporate marketing expenses and
corporate administrative functions (including data services, employee benefits,
legal, insurance, accounting and other corporate overhead) has been included in
the selling and marketing and general and administrative operating expenses in
the statements of revenues and expenses. Depreciation has been computed based
upon a computation of the direct expenses related to the assets sold under the
terms of the Agreement plus an allocation of general corporate depreciation.
Management believes these allocations are reasonable. These allocations are not
necessarily indicative of the costs and expenses that would have resulted if the
Division had been operated as a separate entity.
 
  Accounts Receivable, Net
 
     Accounts receivable represent amounts receivable from the class of hosting
customer subject to the Agreement and are shown net of the allowance for
doubtful accounts. The allowance was approximately $27,000 and approximately
$90,000 at December 31, 1996 and 1997, respectively.

                              HOSTAMERICA DIVISION
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Computer Equipment, Net
 
     Computer equipment is recorded at cost less accumulated depreciation, which
is computed using the straight-line method over the estimated useful lives of
the related assets (three years). Maintenance and repairs are charged to expense
as incurred. Upon sale, retirement or other disposition of these assets, the
cost and the related accumulated depreciation are removed from the respective
accounts and any gain or loss on the disposition is included in income.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
  Revenue Recognition
 
     HostAmerica recognizes revenues ratably over the period for which the Web
site hosting services are provided. Deferred revenue, as reflected on the
accompanying statements of assets and liabilities, represents the amount of
billings recorded in advance of services being provided.
 
  Advertising Expenses
 
     All advertising costs are expensed when incurred. Advertising expenses
allocated to the Division were approximately $1,000, $32,000, and $384,000 for
the years ended December 31, 1995, 1996 and 1997, respectively.
 
  Income Taxes
 
     The Division is not a legal entity. The Division has been included in
HomeCom's consolidated federal income tax returns for all periods prior to June
9, 1998. The Division was not a party to any tax sharing agreement and,
accordingly, no benefit for income taxes has been reflected in the accompanying
statements of revenues and expenses.
 
2. COMPUTER EQUIPMENT
 
     Computer equipment, net, represents the specific assets defined in the
agreement used in the provision of hosting services and is comprised of the
following as of:

3. COMMITMENTS AND CONTINGENCIES
 
     The Division's software and equipment are vulnerable to computer viruses or
similar disruptive problems caused by customers or other Internet users.
Computer viruses or problems caused by third parties could lead to
interruptions, delays or cessation in service to the Division's customers.
Moreover,
 
                                      F-40

                              HOSTAMERICA DIVISION
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
customers of the Division could use computer files and information stored on or
transmitted to Web server computers maintained by the Division to engage in
illegal activities that may be unknown or undetectable by the Division,
including fraud and misrepresentation, and unauthorized access to computer
systems of others. Furthermore, inappropriate use of the Internet by third
parties could also jeopardize the security of customers' confidential
information that is stored in the Division's computer systems. Any such actions
could subject the Division to liability to third parties. The Division does not
have errors and omissions, product liability or other insurance to protect
against risks caused by computer viruses or other misuse of software or
equipment by third parties. Although the Division attempts to limit its
liability to customers for these types of risks through contractual provisions,
there can be no assurance that these provisions will be enforceable.
 
     Various legal proceedings may arise in the normal course of business.
Management does not believe that there are currently any asserted or unasserted
claims that will have a material adverse effect on the statements of assets and
liabilities, statements of revenues and expenses or cash flows of the Division.
 
4. CONCENTRATION OF CREDIT RISKS
 
     Financial instruments that potentially subject the Division to significant
concentrations of credit risk consist principally of accounts receivable.
 
     Concentration of credit risk with respect to trade receivables is monitored
by the Division through ongoing credit evaluations of its customers' financial
condition. No customer accounted for more than 10% of the revenues of the
Division during 1995, 1996 or 1997.

statements of operations and accumulated deficit, and cash flows for the period

December 31, 1997. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     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 amount 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 audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material aspects, the financial position of B.N. Technology, Inc. as of
December 31, 1996 and 1997, and the results of its operations and its cash flows
for the period April 16, 1996 (inception) through December 31, 1996 and the year

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1996 AND 1997
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The summary of significant accounting policies of B.N. Technology, Inc.
(the Company) is presented to assist in understanding the Company's financial
statements. The financial statements and notes are representations of the
Company's management, which is responsible for their integrity and objectivity.
These accounting policies conform to generally accepted accounting principles
and have been consistently applied in the preparation of the financial
statements.
 
  Business activity
 
     The Company was incorporated on April 16, 1996, and is located in Los
Angeles, California. The Company is an Internet Web hosting service provider.
 
  Revenue recognition
 
     Revenue consists primarily of fees for hosting Web sites. Fees received are
earned according to the subscription period sold. Subscription periods are sold
on a monthly, quarterly and annual basis.
 
     Deferred revenue represents fees received from quarterly and annual
subscriptions which extend beyond the current balance sheet date.
 
  Property and equipment
 
     Property and equipment is carried at cost. The cost is depreciated over the
estimated useful lives of the related assets. Depreciation is computed on the
straight-line method for financial reporting purposes and on the accelerated
cost recovery system method for income tax purposes.
 
     Expenditures for major renewals and betterments that extend the useful
lives of property and equipment are capitalized. Expenditures for maintenance
and repairs are charged to expense as incurred.
 
  Advertising
 
     Advertising costs are expensed as incurred. Advertising expense was $8,818
and $98,484 for the period ended December 31, 1996 and the year ended December
31, 1997, respectively.
 
  Use of estimates in preparation of financial statements
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that directly affect the results of reported assets, liabilities,
revenue and expenses. Actual results may differ from these estimates.
 
  Income taxes
 
     Current income taxes are based on the taxable income for the year, as
measured by the current year's tax returns. Deferred income taxes arise
primarily due to differences between the basis of deferred revenue used for
financial statements versus cash basis used for income tax reporting purposes.

                          INDEPENDENT AUDITOR'S REPORT
 
To the Board of Directors and Stockholders
GEN International, Inc. and Subsidiaries
 
     We have audited the accompanying consolidated balance sheet of GEN
International, Inc. and Subsidiaries (formerly Global Entrepreneurs Network,
Inc.) as of December 31, 1995, 1996 and 1997, and the related consolidated
statements of operations, changes in stockholders' deficiency, and cash flows
for the period April 4, 1995 (inception) through December 31, 1995, and the
years ended December 31, 1996 and 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of GEN International, Inc. and
Subsidiaries as of December 31, 1995, 1996 and 1997, and the results of their
operations and their cash flows for the period April 4, 1995 (inception) to
December 31, 1995, and the years ended December 31, 1996, and 1997, in
conformity with generally accepted accounting principles.
 
     The accompanying consolidated financial statements have been prepared
assuming the Company will continue as a going concern. As discussed in Note 9 to
the financial statements, the Company has incurred net losses, and has a working
capital deficiency and a stockholders' deficiency as of December 31, 1997. In
March 1998, Global Entrepreneurs Network, Inc., a wholly-owned subsidiary filed
a voluntary petition for reorganization under Chapter 11 of the Bankruptcy Code.
These conditions raise substantial doubt about the Company's ability to continue
as a going concern. Management's plans with regard to these matters are
discussed in Note 9. The financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

                               DECEMBER 31, 1997
 
NOTE 1. ORGANIZATION, BUSINESS COMBINATIONS AND ACQUISITIONS, AND SUMMARY OF
        SIGNIFICANT ACCOUNTING POLICIES
 
     Organization:  GEN International, Inc. (the "Company"), a successor entity
to Global Entrepreneurs Network, Inc. (Global), is located in St. Petersburg,
Florida and is a global network and information provider connected to the
Internet. The Company also offers storage, transfer, and Web hosting services to
its members worldwide, primarily small and medium sized businesses. The Company
was organized as a shell in June 1997. In this connection, Global, originally
incorporated in April 1995 exchanged its then outstanding common stock
(5,325,000 shares) for the common stock (2,662,500 shares) of the Company. The
Company also issued options to the former stockholders of Global. The financial
statements from inception (April 4, 1995) through the exchange in June 1997,
represent the accounts and activities of Global. In connection with this
exchange, Global became a wholly-owned subsidiary of the Company. The Company
also acquired in June 1997, the outstanding common stock of GEN Events, Inc.,
GEN Network Operations Center, Inc., and GEN Europe, Inc., shell entities with
no assets, liabilities or operations, whose shares were also substantially owned
by the principal shareholder of Global. Nominal consideration was assigned to
the 7,000,000 shares issued by the Company in this connection.
 
  Summary of Significant Accounting Policies
 
     Principles of Consolidation:  The consolidated financial statements include
the accounts of the Company, and its wholly-owned subsidiaries as follows:
 
     - Global Entrepreneurs Network, Inc.
 
     - GEN Network Operations Center, Inc.
 
     - GEN Europe, Inc.
 
     - GEN Events, Inc.
 
     All significant intercompany balances and transactions have been eliminated
in the consolidated financial statements.
 
     Revenue Recognition:  Recurring revenues consist primarily of monthly fees
charged to members for Web hosting services and are recognized at the beginning
of each month for which services are rendered. Other revenues generally
represent one-time set up fees and are recorded as earned. Deferred revenue
consists primarily of the unexpired portion of annual prepaid membership fees.
 
     Property and Equipment:  Property and equipment is stated at cost and
depreciated using the straight-line method over the estimated useful life of the
assets, generally three years for computers and computer related equipment and
five years for other non-computer furniture and equipment. Leasehold
improvements are amortized over the term of the lease.
 
     Capital Leases:  The Company leases certain of its phone and other computer
related equipment under capital lease agreements. The assets and liabilities
under capital leases are recorded at the lesser of the present value of future
minimum lease payments, including estimated bargain purchase options, or the
fair value of the assets under lease. Assets under capital lease are amortized
over the lesser of their estimated useful lives of three to five years or the
term of the lease.
 
     Income Taxes:  Income taxes are computed using the asset and liability
method. Under this method, deferred tax assets and liabilities are determined
based on differences between the financial reporting and

tax bases of assets and liabilities and are measured using the currently enacted
tax rates and laws. There were no deferred taxes in 1995, 1996 and 1997.
 
     Advertising:  The Company expenses advertising costs as they are incurred.
 
     Use of Estimates in the Preparation of Financial Statements:  The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
NOTE 2. PROPERTY AND EQUIPMENT
 
     Property and equipment consist of the following at December 31, 1996 and
1997:

NOTE 3. LINE OF CREDIT
 
     The Company has a line of credit with a financial institution amounting to
$50,000. The line bears interest at 2% above the prime lending rate and is due
on demand.
 
NOTE 4. ADVANCES FROM STOCKHOLDER
 
     Advances from stockholder originally due in September 1996, bear interest
at 18% per annum. Repayment of the advances was extended until such time as the
Company has sufficient resources to satisfy the obligations. Interest expense
for the year ended December 31, 1997 was $7,611. Interest in 1996 was not
material.
 
NOTE 5. STOCK-BASED COMPENSATION
 
     During 1997, the Company issued options to purchase 3,715,000 shares of
common stock of the Company to certain officers, directors, stockholders and
employees at exercise prices ranging from $0.10 to $1.00. The options are
exercisable upon certain vesting requirements and/or in the event the Company
has a public offering.
 
     During 1997, 1,010,000 options not subject to vesting requirements were
exercised for $101,000. Options to purchase 2,705,000 shares of common stock
were outstanding at December 31, 1997 at a weighted average exercise price of
approximately $1.00. All outstanding options were exercisable at December 31,
1997.
 
     In accordance with Accounting Principles Board Statement No. 25 (APB 25),
no compensation cost has been recognized in accounting for the stock options
issued during 1997. Because the Company's stock options have characteristics
significantly different than those of traded options, compensation cost for the
Company's 1997 grants, based upon the fair value method consistent with
Financial Accounting Statement No. 123, is not determinable.

NOTE 6. COMMITMENT
 
     Lease:  The Company had an operating lease for its corporate office, which
expired in January 1998, and was renewed through October 1998. Rent expense for
the years ending December 31, 1997 and 1996, and for the period April 4, 1995
(inception) through December 31, 1995 was $27,000, $29,445 and $5,524,
respectively.
 
NOTE 7. INCOME TAXES
 
     At December 31, 1997, the Company had net operating loss carryforwards of
approximately $1,020,000, which expire in 2010 through 2012. At December 31,
1997, the expected tax benefit from the future realization of this operating
loss carryforward of approximately $401,000 has been offset by an equivalent
valuation allowance, in view of the uncertainty as to ultimate realization.
 
NOTE 8. CAPITAL LEASES
 
     During 1997, the Company entered into capital lease arrangements for
computer equipment and other office equipment. The leases, which expire in 1999
through 2000, require the Company to pay taxes, maintenance and insurance.
Annual minimum commitments under the lease arrangements are as follows:

NOTE 9. GOING CONCERN
 
     As indicated in the accompanying financial statements, the Company and its
wholly-owned subsidiaries, have incurred net operating losses, and as of
December 31, 1997, has a working capital deficiency of approximately $775,000
and a stockholders' deficiency of approximately $610,000. During March 1998,
Global Entrepreneurs Network, Inc. filed a voluntary petition for reorganization
under Chapter 11 of the Federal Bankruptcy Code, and was authorized to continue
managing and operating the business as debtor in possession subject to the
control and supervision of the Bankruptcy Court.
 
     Management of the Company is aggressively seeking additional sources of
capital and financing, and in August, 1998, the Company entered into a contract
with Sage Networks, Inc. for the sale of certain of its assets for cash and
assumption of certain of its liabilities, which sale was subsequently
consummated in September 1998. The ability of the Company to continue as a going
concern is dependent upon obtaining additional capital and financing. The
consolidated financial statements do not include any adjustments that might be
necessary if the Company is unable to continue as a going concern.
 
NOTE 10. SUBSEQUENT EVENTS
 
     In March 1998, the Company effected a 2 for 1 stock split.

                         NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 1997 AND 1998
 
NOTE 1. ORGANIZATION, BUSINESS COMBINATIONS AND ACQUISITIONS, AND SUMMARY OF
        SIGNIFICANT ACCOUNTING POLICIES
 
     Organization:  Digiweb, Inc. ("Digiweb" or the "Company") is a provider of
Web hosting and co-located services catering to small and medium sized
businesses. Based in College Park, Maryland, Digiweb offers three core services:
shared server Web hosting, dedicated server Web hosting and co-located.
 
     Revenue Recognition:  Recurring revenues consist primarily of monthly fees
charged to members for Web hosting services and are recognized ratably over the
periods for which services are rendered. Other revenues generally represent
one-time set up fees and are recorded as earned. Deferred revenue consists
primarily of the unexpired portion of annual prepaid membership fees.
 
     Property and Equipment:  Property and equipment is stated at cost and
depreciated using the straight-line method over the estimated useful life of the
assets, generally three to five years for computers and computer related
equipment and seven years for other non-computer furniture and equipment.
Leasehold improvements are amortized over the term of the lease.
 
     Capital Leases:  The Company leases certain of its autos and other computer
related equipment under capital lease agreements. The assets and liabilities
under capital leases are recorded at the lesser of the present value of future
minimum lease payments, including estimated bargain purchase options, or the
fair value of the assets under lease. Assets under capital lease are amortized
over the lesser of their estimated useful lives of three to five years or the
term of the lease.
 
     Income Taxes:  No provision for income taxes has been recorded in the
financial statements due to the Company's S Corporation status. Individual
stockholders are taxed on their respective shares of the entities' income and
receive the benefits of the entities' income tax credits.
 
     Advertising:  The Company expenses advertising costs as they are incurred.
 
     Use of Estimates in the Preparation of Financial Statements:  The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

the responsibility of the Companies management. Our responsibility is to express
an opinion on these combined financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the combined 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 our audits provide a reasonable basis for our
opinion.

                   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
DESCRIPTION OF BUSINESS
 
     Telephonetics International, Inc. (Telephonetics) and State of the Art,
Inc. were incorporated in the State of Florida in 1982 and 1980, respectively,
for the purpose of providing customized audio programming for telephone hold
lines and other telecommunication applications. Presently such applications
include automated attendant, voice mail, integrated voice response and
computer/telephone integration applications, which collectively comprise the
Companies' sole business segment. The Companies' principle administrative,
production and sales facility is located in Miami, Florida.
 
PRINCIPLES OF COMBINATION
 
     The combined financial statements include the accounts of Telephonetics
International, Inc. and its substantially inactive affiliate corporation, State
of the Art, Inc., collectively, the Companies. Telephonetics' majority
shareholder owns 85% of State of the Art, Inc.'s common stock and substantially
controls its operations. Intercompany advances and transactions have been
eliminated.
 
CASH AND CASH EQUIVALENTS
 
     For the purpose of the statements of cash flows, the Companies consider all
highly liquid debt instruments purchased with an original maturity of three
months or less to be cash equivalents.
 
REVENUE RECOGNITION
 
     A typical sales agreement for services entitles a customer to receive and
requires the Companies to provide upon customer request specified programming
services over a one year period. Billings to customers for such services are
rendered at the date of the agreement and recognized as revenue on a
straight-line basis over the term of the agreement. Revenue from telephone
answering devices and accessory sales are recognized upon shipment to the
customer.
 
INVENTORIES
 
     Inventories are stated at the lower of cost or market using the first in,
first-out method.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is recorded at cost. Depreciation and amortization
is computed by the straight line method based on the estimated useful lives of
the related assets. Leasehold improvements are amortized over the shorter of the
life of the asset or the lease.
 
INCOME TAXES
 
     The Companies, with the consent of all of their shareholders, have elected
to be taxed under the provisions of Subchapter S of the Internal Revenue Code.
Under those provisions, the Companies do not provide for or pay Federal and
certain State corporate income taxes on their taxable income. Instead, the
stockholders are liable for individual Federal and State income taxes, if any,
on their share of the Companies taxable income.
 
PREPARATION OF COMBINED FINANCIAL STATEMENTS
 
     The preparation of the combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the combined financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from estimated amounts.

           SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
 
CONCENTRATION OF CREDIT RISK
 
     The Companies' credit risk relates to cash and cash equivalents and
accounts receivable. Cash and cash equivalents are primarily held in bank
accounts and overnight investments. These banks are insured up to $100,000 by
the FDIC. Periodically, cash balances may exceed this amount. The credit risk
associated with accounts receivable is minimal due to the Companies' customer
base and ongoing control procedures which monitor the credit worthiness of
customers.
 
NEW ACCOUNTING PRONOUNCEMENT
 
     SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities," establishes accounting and reporting standards for derivative
instruments and for hedging activities. It requires that an entity recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The statement applies to
all entities and is effective for all fiscal quarters of fiscal years beginning
after June 15, 1999. The Companies did not engage in derivative instruments or
hedging activities in any periods presented in the financial statements.

</TABLE>
 
2. NOTES PAYABLE
 
     At December 31, 1998, the Companies have a financing agreement with a
financial institution which provides for a demand revolving line of credit with
maximum borrowings of $150,000. Outstanding amounts under this facility bear
annual interest at 1% over the prime rate (8.75% at December 31, 1998), payable
monthly. Amounts borrowed under this facility are collateralized by
Telephonetics International, Inc.'s accounts receivable and guaranteed by the
Company's President and principal shareholder. At December 31, 1998, amounts
outstanding under the line of credit aggregate $90,000.
 
     The revolving line of credit agreement, requires the Companies to comply
with certain covenants, the most restrictive of which requires the Companies to
maintain tangible net worth (as defined) of at least $500,000. At December 31,
1998, the Companies were not in compliance with this covenant and accordingly,
the obligation could be called for repayment.
 
3. NOTE PAYABLE TO SHAREHOLDER
 
     On May 28, 1998, the Companies' principal shareholder loaned $70,000 to the
Companies for working capital purposes. The note bears interest at 10% annually
payable in monthly principal installments of $3,000 beginning September 1998. At
December 31, 1998, outstanding amount due to the principal shareholder
aggregated $50,000.
 
4. RELATED PARTY TRANSACTIONS
 
     During 1997 and 1998, the Companies paid rent to companies owned by the
Companies' principal officers in the amount of $38,500 and $104,000,
respectively.
 
5. SIGNIFICANT CUSTOMER
 
     For the years ended December 31, 1997 and 1998, one customer accounted for
47% and 55% of revenues, respectively; at December 31, 1998, accounts receivable
from this customer amounted to approximately $337,600.
 
6. FINANCIAL INSTRUMENTS
 
     The carrying amounts of financial instruments including certificates of
deposit, accounts receivable, accounts payable and debt approximated fair value
due to the relatively short maturity.

     Rent expense in 1997 and 1998 aggregated approximately $102,000 and
$160,000, including $38,500 and $104,000 to related parties, respectively.
 
     The Companies are required to pay a fee for the use of custom audio
production. During 1997 and 1998, approximately $33,000 and $40,000 of royalties
were paid, respectively.
 
8. DEFERRED COMPENSATION PLAN
 
     The Companies have a defined contribution plan established pursuant to
Section 401(k) of the Internal Revenue Code. Employees contribute to the plan a
percentage of their salaries, subject to certain dollar limitations and the
Companies match a portion of the employees' contributions. The Companies'
contributions to the plan for the years ended December 31, 1997 and 1998
aggregated $16,200 and $17,000, respectively.
 
9. CAPITAL DEFICIT
 
     On December 15, 1997 at a special meeting of the stockholders, an action
was approved to recapitalize Telephonetics by reducing the par value of each
share of common stock from $1 per share to $.001 per share and increasing the
number of authorized shares of common stock from 100,000 shares to 15,000,000
shares. The then issued 100,000 shares of $1 par value common stock (comprised
of 80,000 outstanding shares and 20,000 shares of Treasury stock) were
subsequently exchanged (at a ratio of 73.75 to 1) for 7,375,000 shares of $.001
par value common stock, comprised of 5,900,000 outstanding shares and 1,475,000
shares of Treasury stock. All share and per share data in the accompanying
financial statements have been retroactively restated to give effect to the
recapitalization.
 
     In July 1997, an investor subscribed for the purchase of 100,000 shares of
Telephonetics' recapitalized $.001 par value common stock for aggregate
consideration of $495,000. The shares were issued during 1998 following
consummation of the recapitalization.
 
     During the year ended December 31, 1997, Telephonetics temporarily acquired
all of the outstanding shares of common stock of Quicklab Multimedia Centers,
Inc. in exchange for 2,950,000 shares of common stock. To facilitate the
transaction, for which the Company did not then have sufficient authorized and
unissued shares of common stock, the Company's then sole stockholder contributed
2,950,000 shares owned by him to the Company which were issued to the seller.
The acquisition was subsequently rescinded and the 2,950,000 shares of common
stock were returned to the stockholder. In connection with the rescinded
transaction, the Company loaned Quick Lab Multimedia Centers, Inc. $110,000
under the terms of an unsecured note receivable bearing interest at prime plus
1% (8.75% at

December 31, 1998). During the year ended December 31, 1998, the Company
recorded a $110,000 provision for possible losses on the note.
 
10. SUBSEQUENT EVENT
 
     In January 1999, the Companies entered into a letter of intent with Sage
Networks, Inc. (Sage) for the sale of substantially all their assets and
assumption of substantially all of their liabilities in exchange for $3,000,000
in cash and 140,000 shares of Sage common stock.
 
11. YEAR 2000 ISSUES (UNAUDITED)
 
     Like other companies, the Companies could be adversely affected if the
computer systems we, our suppliers or customers use do not properly process and
calculate date-related information and data from the period surrounding and
including January 1, 2000. This is commonly known as the "Year 2000" issue.
Additionally, this issue could impact non-computer systems and devices such as
production equipment, elevators, etc.
 
     The Companies are implementing a plan to modify their business technologies
to be ready for the year 2000 and are in the process of converting critical data
processing systems. The project is expected to be substantially complete by
June, 1999 and to cost between $125,000 and $150,000. The Companies do not
expect this effort to have a significant effect on operations.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders
of Net Daemons Associates, Inc.:
 
     We have audited the accompanying balance sheets of Net Daemons Associates,
Inc. (the "Company") as of December 31, 1997 and 1998, and the related
statements of income, stockholders' deficit and cash flows for the years then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Company at December 31, 1997 and 1998,
and the results of its operations and its cash flows for the years then ended in
conformity with generally accepted accounting principles.

                     YEARS ENDED DECEMBER 31, 1997 AND 1998
 
1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Net Daemons Associates, Inc. ("NDA" or the "Company") specializes in
providing business with team-based network and system administration solutions.
NDA network and system services include outsourced network/system
administration; LAN/WAN design and implementation; network growth and transition
planning; Internet connectivity; security consulting; and customized network
solutions. In addition, NDA provides Web site development and network consulting
services.
 
     NEW ACCOUNTING PRONOUNCEMENTS -- During the year, the Company adopted
Financial Accounting Standards Board ("FASB") Statement No. 130, "Reporting
Comprehensive Income." Statement No. 130 requires the reporting of comprehensive
income in addition to net income from operations. Comprehensive income is a more
inclusive financial reporting methodology that includes disclosure of certain
financial information that historically has not been recognized in the
calculation of net income. Comprehensive income encompasses all changes in
stockholders' equity (except those arising from transactions with stockholders).
The Company had no other components of comprehensive income. As this new
standard only requires additional information in the financial statements, it
does not affect the Company's financial position or results of operations.
 
     USE OF ESTIMATES -- The preparation of financial statements in accordance
with generally accepted accounting principles requires the use of estimates.
These estimates include the allowance for doubtful accounts and certain accruals
and are based upon assumptions developed by management about the appropriate
carrying value of assets and liabilities. Actual results could differ from these
estimates.
 
     REVENUE RECOGNITION -- Revenue from consulting services is recognized as
the services are rendered, provided that no significant obligations remain and
collection of the receivable is considered probable. Generally, contracts call
for billings on a time and materials basis; however, in instances when a fixed
fee contract is signed, revenue is recognized on a percentage-of-completion
basis. At December 31, 1997 and 1998, NDA had $62,910 and $52,127 of deferred
revenue recorded, respectively.
 
     CONCENTRATION OF CREDIT RISK -- The majority of NDA's revenue is from
customers in high technology industries, who are not required to provide
collateral. NDA's customers are dispersed over a wide geographic area and are
subject to periodic review under the Company's credit policies. The Company does
not believe that it is subject to any unusual credit risks, other than the
normal level of risk attendant to operating its business.
 
     PROPERTY AND EQUIPMENT -- Property and equipment are recorded at cost and
depreciated using the straight-line method over their estimated useful lives
(three to seven years). Leasehold improvements are amortized over the life of
the lease.
 
     INCOME TAXES -- Deferred income taxes are provided for the tax consequences
of differences in bases between assets and liabilities for book and tax
purposes. Deferred taxes are measured using currently enacted tax rates which
are expected to be in effect when such differences reverse.
 
     STOCK-BASED COMPENSATION -- Compensation cost associated with awards of
stock or options to employees is measured using the intrinsic-value method
prescribed by Accounting Principles Board Opinion No. 25 (see Note 6).
 
     RECLASSIFICATIONS -- Certain amounts in the financial statements have been
reclassified to conform with the 1998 presentation.

4. NOTE PAYABLE -- BANK
 
     Note payable -- bank represents the outstanding balance under a $400,000
working capital line of credit and a $100,000 line with a term conversion
feature ("the conversion line"). Interest on the lines are payable monthly based
on prime (7.75% at December 31, 1998). The lines are secured by and cross-
collateralized by substantially all assets of NDA, are personally guaranteed by
NDA's stockholders, and require the maintenance of customary financial covenants
including minimum retained earnings of $475,000. The lines are subject to
renewal annually and expires on July 1, 1999. The conversion line is to be
utilized to finance 80% of the purchase price of new equipment and converts to a
term loan in July 1999. After conversion, the loan will be payable in 48 equal
monthly installments of principal plus interest at the bank's then prime rate.
Amounts available under the lines were $500,000 at December 31, 1998.
 
5. LONG-TERM DEBT
 
     EQUIPMENT LOAN -- The equipment loan requires monthly principal and
interest payments with principal payments based on a four-year straight-line
amortization schedule. Interest is based on prime (7.75% at December 31, 1998).
The equipment loan is secured by substantially all assets of NDA and is
personally guaranteed by NDA's stockholders.
 
     TERM LOAN -- In connection with the acquisition of an automobile in June
1996, NDA entered into a term loan (the "term loan") with a bank for $23,504.
The term loan requires monthly payments of principal and interest (at 8.75%)
through May 2001.
 
     STOCKHOLDER DEBT -- In connection with the repurchase of 855,000 shares of
common stock in December 1997, the Company entered into a $940,000 note payable
agreement (the "note payable"). This agreement calls for principal payments in
the amount of $125,333 to be made annually in 1999 through 2003 with a balloon

6. STOCKHOLDERS' DEFICIT
 
     COMMON STOCK -- During fiscal year 1997, NDA issued 62,500 common shares at
a price of $2.00 per share. Of the $125,000 in proceeds due from the sale of
these shares, $100,000 had been collected, leaving an outstanding balance of
$25,000 at December 31, 1997. On February 19, 1998, the outstanding balance was
collected.
 
     TREASURY STOCK -- In December 1997, NDA purchased 855,000 shares of common
stock. NDA's purchases of shares of common stock are recorded as "Treasury
Stock" and result in a reduction of "Stockholders' Deficit."
 
     STOCK OPTION PLAN -- NDA's Incentive Stock Option Plan (the "Plan"),
established in December 1996, provides for grants of options to purchase up to
200,000 shares of common stock. Grants may be in the form of incentive stock
options or nonqualified options. Exercise prices and vesting periods are
determined by the Board on the date of grant. Options generally vest ratably
over a four-year period. A summary of activity in the Plan is as follows:

     PRO FORMA DISCLOSURE -- As described in Note 1, NDA uses the
intrinsic-value method to measure compensation for equity awards to employees.
Had NDA used the fair-value method to measure compensation, reported net income
would have been $64,577 in 1997 and $9,097 in 1998.
 
     The minimum-value method was used to measure the fair value of equity
awards in this disclosure. Key assumptions used to apply this pricing model were
average risk-free rates of 6% and expected option lives of ten years. The
estimated fair value of awards made in 1997 and 1998 were $94,710 and $190,332,
respectively.
 
     RESERVED SHARES -- At December 31, 1997 and 1998, 200,000 shares of common
stock were reserved for issuance upon exercise of options.

Agreement also provides for contingent consideration of $500,000 in cash and
74,963 shares of Sage common stock if certain gross revenue and gross margin
targets are met in the twelve months period following the acquisition. The
transaction closed on February 17, 1999. As a result of the acquisition, on

To Shareholder
    
   
Rancher 1 Corp. (formerly known as Interliant, Inc.)
    
 
   
     We have audited the accompanying balance sheets of Rancher 1 Corp.
(formerly known as Interliant, Inc.) (the "Company") as of December 31, 1997 and
1998, and the related statements of operations, shareholder's deficit and cash
flows for each of the three years in the period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
    
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Rancher 1 Corp. (formerly
known as Interliant, Inc.) at December 31, 1997 and 1998, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.

                 YEARS ENDED DECEMBER 31, 1996, 1997, AND 1998
 
1.  DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
     Interliant, Inc. (the "Company") was organized under the laws of the State
of Texas on July 12, 1993, under the name Wolf Communications Company. The
Company's name was changed to Interliant, Inc., effective January 20, 1997.
Interliant, Inc., is a privately owned company that provides secure
network-based hosting and messaging services on a Lotus Notes platform, enabling
worldwide continuously available remote access to business-critical applications
and data. The Company also provides vertical solutions for various markets
including distance learning, sales force automation, legal, and mortgage
banking. It is also developing hosting solutions for Microsoft Exchange and
Microsoft's Commercial Internet System, as well as a remote server management
solution.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying value of the Company's financial instruments, except notes
payable to shareholder and related party and the capital lease obligation,
approximate fair value. The fair value of notes payable to shareholder and
related party and the capital lease obligation are not determinable as the
Company's borrowings are from the shareholder and a related party and the
capital lease obligation is guaranteed by the shareholder.
 
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.
 
STOCK-BASED COMPENSATION
 
     The Company grants stock options to employees for shares with an exercise
price no less than the value of the shares at the date of grant. The company
accounts for such stock option grants in accordance with Accounting Principles
Board Opinion No. 25, Accounting for Stock Issued to Employees ("APB 25").
 
REVENUE RECOGNITION
 
     Revenues consist primarily of network service and related fees for
services, generally provided under contractual periods ranging from one to
twelve months. Revenues from these services are generally recognized when the
services are performed. Revenues in excess of amounts billed are accrued and
presented as unbilled revenue in the accompanying balance sheets.
 
ADVERTISING EXPENSES
 
     All advertising costs are expensed as incurred. Advertising expenses were
approximately $122,000, $415,000, and $571,000 for the years ended December 31,
1996, 1997, and 1998, respectively.
 
COST OF SERVICE REVENUE
 
     Cost of service revenue includes internally-funded research and development
costs, which are expensed as incurred. Research and development costs were
approximately $600,000, $1,100,000, and $1,500,000 in 1996, 1997, and 1998,
respectively.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is stated at cost. Depreciation is provided using
the straight-line method over the estimated useful lives of the assets as
follows:
 
<TABLE>
<S>                                                           <C>
Computer equipment and software.............................       3 years
Furniture, fixtures and office equipment....................  5 to 7 years
</TABLE>
 
     Amortization of leasehold improvements is provided using the straight-line
method over the shorter of the remaining estimated useful lives or the lease
terms. Depreciation expense in 1997 of approximately $287,000 is presented on
the statements of operations as an offset to the gain on settlement of
litigation.
 
     The costs of ordinary maintenance and repairs are charged to expense while
renewals and replacements are capitalized.
 
INCOME TAXES
 
     The shareholder has elected S corporation status for the Company for
federal income tax purposes. Under S corporation regulations, revenues and
expenses of the Company are reportable for federal income tax purposes in the
income tax return of the shareholder. Accordingly, no provision for federal
income tax is included in the accompanying financial statements.
 
CONCENTRATION OF CREDIT RISK
 
     Financial instruments which subject the Company to concentrations of credit
risk consist principally of accounts receivable. The Company provides credit, in
the normal course of business, to a number of geographically dispersed
customers, primarily within the United States. Collateral is generally not
required on these receivables. The Company maintains allowances for potential
credit losses, and customers can be denied access to services in the event of
non-payment. During 1997 and 1998, the Company's largest customer represented
approximately 10% of total revenues.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
     Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, Reporting Comprehensive Income ("SFAS 130"). SFAS
130 establishes new rules for the reporting and display of comprehensive income
and its components. Certain items which were previously required to be reported
separately in shareholder's equity, such as unrealized gains or losses on
available-for-sale securities, minimum pension liability adjustments and foreign
currency translation adjustments, are now required to be included in other
comprehensive income. For 1996, 1997, and 1998 the Company's comprehensive
income was the same as net income, and the adoption of SFAS 130 had no impact on
the presentation of the financial statements.
 
     In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, Disclosures about Segments of an
Enterprise and Related Information ("SFAS 131"). SFAS 131 requires disclosure of
certain information regarding operating segments, products, services, geographic
areas of operation and major customers. The disclosures prescribed by SFAS 131
are effective for the year ended December 31, 1998. The Company has determined
that it does not have separately reportable segments, as defined by SFAS 131,
and thus no segment disclosures have been presented.
 
     In March 1998, the AICPA issued Statement of Position 98-1, Accounting for
the Costs of Computer Software Developed or Obtained for Internal Use (SOP
98-1), which is effective for the financial statements for fiscal years
beginning after December 15, 1998. SOP 98-1 will result in the capitalization of

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
certain qualifying costs incurred in the development of software for internal
use; however, the adoption of SOP 98-1 is not expected to have a material impact
on the Company's earnings or financial position.
 
2.  INVESTMENT IN AND ADVANCES TO JOINT VENTURE
 
     The Company is a 50% partner in TITLELINK, L.L.C., a joint venture which
offers a network-based service to facilitate the closing of real estate
transactions within the financial community. The Company provides working
capital requirements as needed. The Company has provided an allowance against
its advances to the joint venture of approximately $30,000 and $114,000 at
December 31, 1997 and 1998, respectively, which is included in investment in and
advances to joint venture.
 
3.  PROPERTY AND EQUIPMENT
 
     Property and equipment consists of the following at December 31:

4.  NOTES PAYABLE TO SHAREHOLDER AND RELATED PARTY
 
     Notes payable to shareholder and related party includes unsecured
borrowings from the Company's shareholder totaling $4,310,000 and $7,910,000 at
December 31, 1997 and 1998, respectively, and unsecured borrowings from a
related party totaling $6,515,000 and $7,215,000 at December 31, 1997 and 1998,
respectively. These advances have been used to fund the Company's operations.
These notes bear interest, payable monthly, at annual rates ranging from 5.5% to
6.1% in 1997, and 4.3% to 5.6% in 1998. The borrowings mature on March 31, 1999.
 
     The Company paid interest associated with the notes payable to affiliates
of approximately $199,000, $449,000, and $696,000 in 1996, 1997, and 1998,
respectively.
 
5.  RELATED PARTY TRANSACTIONS
 
     The Company has an informal agreement with a related party whereby the
Company provides certain administrative services to the related party. The
related party compensates the Company for these services on a monthly basis,
which totaled $12,000, $48,000, and $48,000 in 1996, 1997, and 1998,
respectively. The amount due to the Company for these services totaled $12,000
at December 31, 1998, and there was no related amount due to the Company at
December 31, 1997.
 
6.  EMPLOYEE BENEFIT PLAN
 
     Substantially all of the Company's employees are participants in a
discretionary, defined contribution plan with salary deferral contributions as
provided under Section 401(k) of the Internal Revenue Code. Voluntary salary
deferral contributions are made by employees, subject to a maximum of 15% of
annual compensation and are matched 100% of the first 5% by Company
contributions. The charge to expense for

the Company's contributions was $109,000, $254,000, and $404,000 for the years
ended December 31, 1996, 1997, and 1998, respectively.
 
7.  STOCK SPLIT
 
     Effective December 16, 1996, the Board of Directors approved a four-for-one
split of the Company's common stock effected in the form of a stock dividend,
resulting in a total of 10,000,000 shares outstanding. All references in the
financial statements which relate to the number of shares of Common Stock have
been restated to reflect the stock split.
 
8.  EMPLOYEE STOCK OPTION PLAN
 
     In 1995, the Company's sole director (the "Director") adopted the 1995
Employee Stock Option Plan (the "Option Plan"), pursuant to which options to
purchase up to an aggregate of 4,000,000 shares of the Company's common stock
may be granted. The Option Plan is administered by the Director. Among other
things, the Director determines which employees will receive options, the number
of shares covered by any option granted, and the exercise price and other terms
and conditions of each such option.
 
     All options granted under the Option Plan are nontransferable except by the
laws of descent and distribution. All options also expire ten years after the
date of grant or upon earlier termination of employment unless due to death,
disability, or retirement, in which case the option remains exercisable for an
additional three months in the case for Incentive Options and one year for
Non-Qualified Options. Options granted vest over periods ranging from immediate
vesting to vesting in equal increments over four years from the date of grant.
The exercise price of the options approximated the fair value of the common
stock on the date of grant, and accordingly, no compensation expense has been
recorded. The weighted-average remaining contractual life of options at December
31, 1996, 1997, and 1998 was 9.7 years, 8.8 years, and 8.0 years, respectively.

</TABLE>
 
     At December 31, 1996, 1997, and 1998, the Company had reserved 4,000,000
shares of common stock for issuance in connection with the exercise of stock
options.
 
     The Company has elected to follow APB 25 and related interpretations in
accounting for employee stock options. Accordingly, no compensation expense has
been recognized for these stock options. Pro forma information regarding net
income and earnings per share is required by FASB Statement No. 123, Accounting
for Stock-Based Compensation ("FAS 123"), which also requires that the
information be determined as if the Company had accounted for its employee stock
options under the fair value method of FAS 123. The fair value for these options
was estimated at the date of grant using a minimum value option pricing model
with the following weighted-average assumptions:

     The minimum value method calculated the fair value of these options as
zero; therefore, pro forma net loss is the same as net loss for each year
presented.

     Total rent expense for operating leases for the years ended December 31,
1996, 1997, and 1998 was $797,000, $1,700,000, and $1,449,000, respectively.
 
     The Company has a facility with a bank for letters of credit totaling
$541,000 at December 31, 1998 relating to the Company's data center operating
lease. There were no amounts outstanding under the letter of credit facility at
December 31, 1998.
 
10.  LITIGATION
 
     In 1997 and 1998, the Company received proceeds of $2,500,000 and $600,000,
respectively, from the settlement of legal claims relating to a trademark
dispute. These amounts are presented in the statements of operations net of
costs related to the settlement of $1,148,000 in 1997.
 
     The Company is involved in various lawsuits and legal proceedings which
have arisen in the normal course of business. While the ultimate results of
these matters cannot be predicted with certainty, management does not expect
them to have a material adverse effect on the financial position of the Company.
 
11.  SUBSEQUENT EVENT
 
   
     In February 1999, the shareholder reached an agreement in principle to sell
substantially all of the assets and certain liabilities of the Company. The
transaction closed on March 10, 1999. The Company has obtained approval of the
proposed transaction with the holders of outstanding borrowings. On March 10,
1999, the Company changed its name to Rancher 1 Corp.
    
 
12.  YEAR 2000 ISSUE (UNAUDITED)
 
     Currently, many computer and software products are coded to accept
two-digit entries in the date code field. These date code fields will need to
accept four-digit entries to distinguish 21st century dates from 20th century
dates. As a result, many companies' software and computer systems, including the
Company's, may need to be upgraded or replaced in order to comply with Year 2000
requirements. We

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
recognize the need to ensure that our operations will not be adversely impacted
by Year 2000 software and computer system failures.
 
  State of Readiness
 
     The Company has made a preliminary assessment of the Year 2000 readiness of
its information technology ("IT") systems, including the hardware and software
that enable it to provide and deliver its solutions, and its non-IT systems. The
Company's plan consists of (i) quality assurance testing of its internally
developed proprietary software and systems; (ii) contacting third-party
suppliers, vendors and licensors of material hardware, software and services
that are both directly and indirectly related to the delivery of the Company's
solutions to it customers; (iii) assessment of repair or replacement
requirements; (iv) repair or replacement; (v) implementation; and (vi) creation
of contingency plans in the event of Year 2000 failures. The Company is
currently assessing the materiality of its IT and non-IT systems and will seek
assurances of Year 2000 compliance from providers of material systems. Until
such testing is complete and such vendors and providers are contacted, the
Company will not be able to completely evaluate whether its IT systems or non-IT
systems will need to be revised or replaced. The Company plans to complete its
Year 2000 evaluation during the second half of 1999.
 
  Costs
 
     To date, the Company has not incurred any material expenditures in
connection with identifying or evaluating Year 2000 compliance issues. Most of
its expenses have related to, and are expected to continue to relate to, the
internal staffing costs associated with the evaluation process and Year 2000
compliance matters generally. At this time, the Company does not possess the
information necessary to estimate the potential costs of revisions to its
software and systems should such revisions be required or the replacement of
third party software, hardware or services that are determined not to be Year
2000 compliant. Although the Company does not anticipate that such expenses will
be material, such expenses if higher than anticipated, could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
  Risks
 
     The Company is not currently aware of any Year 2000 compliance problems
relating to its IT or non-IT systems that would have a material adverse effect
on the Company's business, results of operations and financial condition. There
is no assurance that the Company will not discover Year 2000 compliance problems
in its software and systems that will require substantial revisions. In
addition, there is no assurance that third party software, hardware or services
incorporated into the Company's material IT and non-IT systems will not need to
be revised or replaced, all of which could be time consuming and expensive. The
failure of the Company to fix or replace its software, hardware or services on a
timely basis could result in lost revenues, increased operating costs and the
loss of customers and other business interruptions, any of which could have a
material adverse effect on the Company's business, results of operations and
financial condition. Moreover, the failure to adequately address Year 2000
compliance issues in its IT and non-IT systems could result in claims of
mismanagement, misrepresentation or breach of contract and related litigation,
which could be costly and time-consuming to defend. In addition, there can be no
assurance that governmental agencies, utility companies, telecommunication
companies, other Internet service providers, third party service providers,
hardware and software manufacturers and others outside Interliant control will
be Year 2000 compliant. The failure by such entities to be Year 2000 compliant
could result in a systemic failure beyond the control of the Company such as a
prolonged Internet, telecommunications or electrical failure, which could also
prevent the Company from delivering its services to its customers, decrease the
use of the Internet or prevent users from accessing the Web sites

of its customers. Any of these occurrences could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
  Contingency Plan
 
     As discussed above, the Company is engaged in an ongoing Year 2000
assessment and has not yet developed any contingency plans. The responses
received from third-party vendors and service providers will be taken into
account in determining the nature and extent of any contingency plans.

     We intend to offer our common stock outside the United States and Canada
through a number of international managers and in the United States and Canada
through a number of U.S. underwriters. Merrill Lynch International, Donaldson,
Lufkin & Jenrette International and CIBC World Markets International Limited are
acting as lead managers for each of the international managers named below.
Subject to the terms and conditions set forth in an international purchase
agreement among us and the international managers, and concurrently with the
sale of 6,125,000 shares of common stock to the U.S. underwriters, we have
agreed to sell to the international managers, and each of the international
managers severally and not jointly has agreed to purchase from us, the number of
shares of common stock set forth opposite its name below.

     We have also entered into a U.S. purchase agreement with certain
underwriters in the United States and Canada for whom Merrill Lynch, Pierce,
Fenner & Smith Incorporated, Donaldson, Lufkin & Jenrette and CIBC World Markets
Corp. are acting as U.S. representatives. Subject to the terms and conditions
set forth in the U.S. purchase agreement, and concurrently with the sale of
875,000 shares of common stock to the international managers pursuant to the
international purchase agreement, we have agreed to sell to the U.S.
underwriters and the U.S. underwriters severally have agreed to purchase from us
an aggregate of 6,125,000 shares of common stock. The initial public offering
price per share and the total underwriting discount per share of common stock
are identical under the U.S. purchase agreement and the international purchase
agreement.
 
     In the international purchase agreement and the U.S. purchase agreement,
the several international managers and the several U.S. underwriters have
agreed, subject to the terms and conditions set forth therein, to purchase all
of the shares of common stock being sold pursuant to each such agreement if any
of the shares of common stock being sold pursuant to such agreement are
purchased. In the event of a default by an underwriter, the U.S. Purchase
Agreement and the international purchase agreement provide that, in certain
circumstances, the purchase commitments of the nondefaulting underwriters may be
increased or the purchase agreements may be terminated. The closings with
respect to the sale of shares of common stock to be purchased by the U.S.
underwriters and the international managers are conditioned upon one another.
 
     We have agreed to indemnify the U.S. underwriters and the international
managers against some liabilities, including some liabilities under the
Securities Act, or to contribute to payments the U.S. underwriters and the
international managers may be required to make in respect of those liabilities.
 
     The shares of common stock are being offered by the several underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to approval of certain legal matters by counsel for the

underwriters and certain other conditions. The underwriters reserve the right to
withdraw, cancel or modify such offer and reject orders in whole or in part.
 
COMMISSIONS AND DISCOUNTS
 
     The lead managers have advised us that the lead managers propose initially
to offer the shares of common stock to the public at the initial public offering
price set forth on the cover page of this prospectus, and to certain dealers at
such price less a concession not in excess of $     per share of common stock.
The international managers may allow, and such dealers may reallow, a discount
not in excess of $     per share of common stock to certain other dealers. After
the initial public offering, the public offering price, concession and discount
may change.
 
     The following table shows the per share and total public offering price,
underwriting discount to be paid by us to the U.S. underwriters and the
international managers and the proceeds before expenses to us. This information
is presented assuming either no exercise or full exercise by the U.S.
underwriters and the international managers of their over-allotment options.

     The expenses of the offerings (exclusive of the underwriting discount and
commissions) are estimated at $1.4 million and are payable by us.
 
INTERSYNDICATE AGREEMENT
 
     The international managers and the U.S. underwriters have entered into an
intersyndicate agreement that provides for the coordination of their activities.
Under the terms of the intersyndicate agreement, the international managers and
the U.S. underwriters are permitted to sell shares of our common stock to each
other for purposes of resale at the initial public offering price, less an
amount not greater than the selling concession. Under the terms of the
intersyndicate agreement, the U.S. underwriters and any dealer to whom they sell
shares of our common stock will not offer to sell or sell shares of our common
stock to persons who are non-U.S. or non-Canadian persons or to persons they
believe intend to resell to persons who are non-U.S. or non-Canadian persons,
and the international managers and any dealer to whom they sell shares of common
stock will not offer to sell or sell shares of common stock to U.S. persons or
to Canadian persons or to persons they believe intend to resell to U.S. or
Canadian persons, except in the case of transactions under the terms of the
intersyndicate agreement.
 
OVER-ALLOTMENT OPTION
 
     We have granted options to the international managers, exercisable for 30
days after the date of this prospectus, to purchase up to an aggregate of
130,000 additional shares of common stock at the public offering price set forth
on the cover page of this prospectus, less the underwriting discount. The
international managers may exercise this option solely to cover over-allotments,
if any, made on the sale of the common stock offered hereby. To the extent that
the international managers exercise this option, each international managers
will be obligated, subject to certain conditions, to purchase a number of
additional shares of common stock proportionate to such international managers's
initial amount reflected in the foregoing table.
 
     We also have granted an option to the U.S. underwriters, exercisable for 30
days after the date of this prospectus, to purchase up to an aggregate of
920,000 additional shares of common stock to cover over-allotments, if any, on
terms similar to those granted to the international managers.

RESERVED SHARES
 
     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to 350,000, or 5%, of the shares offered hereby to be
sold to some of our directors, officers, employees, distributors, dealers,
business associates and related persons. The number of shares of common stock
available for sale to the general public will be reduced to the extent those
persons purchase such reserved shares. Any reserved shares which are not orally
confirmed for purchase within one day of the pricing of this offering will be
offered by the underwriters to the general public on the same terms as the other
shares offered in this prospectus.
 
NO SALES OF SIMILAR SECURITIES
 
     For a period of 180 days after the date of this prospectus, we, our
executive officers, directors and stockholders, have agreed not to directly or
indirectly, without approval by Merrill Lynch on behalf of the underwriters:
 
     - Offer, pledge, sell, dispose of or transfer any shares of common stock or
       securities convertible into common stock;
 
     - Enter into any agreement that transfers any part of the economic
       consequence of ownership of the common stock; or
 
     - Seek or exercise any right to register any share of common stock or
       security convertible into common stock.
 
     Our stockholders do, however, have the right to:
 
     - Transfer the securities as a gift, if the recipient agrees to be bound by
       the provisions of the lock-up agreement; or
 
     - Pledge their securities to us in consideration for a loan from us.
 
     In addition, we have the right to transfer common stock in connection with
an acquisition, if any recipient of such shares agrees to be bound by the
provisions of the lock-up agreement.
 
QUOTATION ON THE NASDAQ NATIONAL MARKET
 
     Our common stock has been approved for quotation on the Nasdaq National
Market, subject to official notice of issuance, under the symbol "INIT."
 
     Before this offering, there has been no public market for our common stock.
The initial public offering price will be determined through negotiations
between us and the U.S. representatives and the lead managers. The factors to be
considered in determining the initial public offering price, in addition to
prevailing market conditions, are expected to be the valuation multiples of
publicly traded companies that the U.S. representatives and the lead managers
believe to be comparable to us, certain of our financial information, the
history of, and the prospects for, our company and the industry in which we
compete, and an assessment of our management, its past and present operations,
the prospects for, and timing of, our future revenues, the present state of our
development, and the above factors in relation to market values and various
value measures of other companies engaged in activities similar to ours. There
can be no assurance that an active trading market will develop for our common
stock or that our common stock will trade in the public market subsequent to
this offering at or above the initial public offering price.
 
     The underwriters do not expect sales of the common stock to be made to any
accounts over which they exercise discretionary authority to exceed 5% of the
number of shares being offered in this offering.

PRICE STABILIZATION, SHORT POSITIONS AND PENALTY BIDS
 
     Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters and
certain selling group members to bid for and purchase our common stock. As an
exception to these rules, the U.S. representatives are permitted to engage in
certain transactions that stabilize the price of our common stock. Such
transactions consist of bids or purchases for the purpose of pegging, fixing or
maintaining the price of our common stock.
 
     If the underwriters create a short position in our common stock in
connection with the offering contemplated hereby, i.e., if they sell more shares
of our common stock than are set forth on the cover page of this prospectus, the
U.S. representatives may reduce that short position by purchasing our common
stock in the open market. The U.S. representatives may also elect to reduce any
short position by exercising all or part of the over-allotment option described
above.
 
     The U.S. representatives may also impose a penalty bid on our underwriters
and selling group members. This means that if the U.S. representatives purchase
shares of our common stock in the open market to reduce the underwriters' short
position or to stabilize the price of the our common stock, they may reclaim the
amount of the selling concession from the underwriters and selling group members
who sold those shares.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of our common stock to the extent that it
discourages resales of our common stock.
 
     Neither we nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of our common stock. In addition, neither
we nor any of the underwriters makes any representation that the U.S.
representatives will engage in such transactions or that such transactions, once
commenced, will not be discontinued.
 
UK SELLING RESTRICTIONS

and, prior to the expiration of the period of six months from the closing date,

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a Delaware corporation may 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, 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 interests of the
corporation, and, with respect to any criminal action or proceeding, had no
cause to believe his conduct was unlawful.
 
     Section 145(b) of the DGCL provides that a Delaware corporation may
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 such
person acted in any of the capacities set forth above, against expenses actually
and reasonably incurred by him in connection with the defense or settlement of
such action or suit if he acted under similar standards, except that no
indemnification may 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 that the court in which such action or suit was brought shall
determine that despite the adjudication of liability, such person is fairly and
reasonably entitled to be indemnified for such expenses which the court shall
deem proper.
 
     Section 145 of the DGCL further provides that to the extent a director or
officer of a corporation has been successful in the defense of any action, suit
or proceeding referred to in subsections (a) and (b) or in the defense of any
claim, issue, or matter therein, he shall be indemnified against any expenses
actually and reasonably incurred by him in connection therewith; that
indemnification provided for by Section 145 shall not be deemed exclusive of any
other rights to which the indemnified party may be entitled; and that the
corporation may purchase and maintain insurance on behalf of a director,
officer, employee or agent of the corporation against any liability asserted
against him or 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 liabilities under Section 145.
                                      II-1
<PAGE>   192
 
     Section 102(b)(7) of the DGCL provides that a corporation in its original
certificate of incorporation or an amendment thereto validly approved by
stockholders may eliminate or limit personal liability of members of its board
of directors or governing body for breach of a director's fiduciary duty.
However, no such provision may eliminate or limit the liability of a director
for breaching his duty of loyalty, failing to act on good faith, engaging in
intentional misconduct or knowingly violating a law, paying a dividend or
approving a stock repurchase which was illegal or obtaining an improper personal
benefit. A provision of this type has no effect on the availability of equitable
remedies, such as injunction or rescission, for breach of fiduciary duty.
Interliant's Restated Certificate of Incorporation contains such a provision.
 
     Interliant's Certificate of Incorporation and By-Laws provide that
Interliant shall indemnify officers and directors and, to the extent permitted
by the Board of Directors, employees and agents of Interliant, to the full
extent permitted by and in the manner permissible under the laws of the State of
Delaware. In addition, the By-Laws permit the Board of Directors to authorize
Interliant to purchase and maintain insurance against any liability asserted
against any director, officer, employee or agent of Interliant arising out of
his capacity as such.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
     In the three years preceding the filing of this Registration Statement,
Interliant has issued securities that were not registered under the Securities
Act of 1933, as amended (the "Securities Act") to a limited number of persons,
as described below.
 
     Interliant believes that the transactions described below were exempt from
registration under the Securities Act pursuant to Section 4(2) of the Securities
Act, or Regulation D promulgated thereunder, as transactions by an issuer not
involving public offering, or pursuant to Rule 701 promulgated under Section
3(b) of the Securities Act, as transactions pursuant to compensatory benefit
plans and contracts relating to compensation. The recipients of securities in
each such transaction represented that they were acquiring the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof and appropriate legends were affixed to the share
certificates issued in such transactions. All recipients had adequate access,
through their relationships with Interliant, to information about Interliant, or
were given an adequate opportunity to review information about Interliant.

has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and this offering of such securities at the
     time shall be deemed to be the initial bona fide offering thereof.

                AMENDED AND RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                                INTERLIANT, INC.

                  Interliant, Inc. (hereinafter called the "Corporation"), a
corporation organized and existing under the laws of the State of Delaware,
hereby certifies as follows:

   
                  The Corporation was originally incorporated under the name of
Sage Networks, Inc., and the original Certificate of Incorporation was filed
with the Secretary of State of the State of Delaware on December 8, 1997. An
Amended and Restated Certificate of Incorporation of the Corporation was filed
with the Secretary of State of the State of Delaware on March 2, 1998. Such
certificate was amended pursuant to a Certificate of Amendment of Certificate of
Incorporation of the Corporation filed with the Secretary of State of the State
of Delaware on July 28, 1998, a Certificate of Amendment of Certificate of
Incorporation of the Corporation filed with the Secretary of State of the State
of Delaware on January 26, 1999, a Certificate of Amendment of Certificate of
Incorporation of the Corporation filed with the Secretary of State of the State
of Delaware on March 2, 1999 and a Certificate of Amendment of Certificate of
Incorporation of the Corporation filed with the Secretary of State of the State
of Delaware on March 11, 1999. The latter Certificate of Amendment changed the
name of the Corporation to Interliant, Inc.
    

                   1. Pursuant to Sections 242 and 245 of the Delaware General
   Corporation Law, this Amended and Restated Certificate of Incorporation
   restates and integrates and further amends the provisions of the Certificate
   of Incorporation of the Corporation.

                   2. The text of the Certificate of Incorporation of the
   Corporation is hereby restated, integrated and amended to read in its
   entirety as follows:
<PAGE>   2
                  FIRST:   The name of the Corporation is Interliant, Inc.

                  SECOND: The address of the registered office and registered
agent in this state is Corporation Service Company, 1013 Centre Road in the City
of Wilmington, County of New Castle, and the name of the registered agent at
said address is Corporation Service Company.

                  THIRD: The nature of the business of the Corporation and its
purpose is to engage in any lawful act or activity for which corporations may be
organized under the Delaware General Corporation Law (the "DGCL").

   
                  FOURTH: The authorized capital stock of the Corporation shall
consist of (i) 2,647,658 shares of Series A Convertible Preferred Stock, par
value $.01 per share (the "Series A Preferred"), (ii) [200,000,000] shares of
Common Stock, par value $.01 per share (the "Common Stock"), and (iii)
[1,000,000] shares of preferred stock, par value $.01 per share (the "Preferred
Stock").
    

                  The Corporation shall reserve at all times so long as any
shares of Series A Preferred remain outstanding, free from preemptive rights,
out of its treasury stock or its authorized but unissued shares of Common Stock,
or both, solely for the purposes of effecting the conversion of the shares of
Series A Preferred, sufficient shares of Common Stock to provide for the
conversion of all outstanding shares of Series A Preferred.

                  The Corporation shall from time to time in accordance with the
laws of the State of Delaware increase the authorized amount of its Common Stock
if at any time the number of shares of Common Stock remaining unissued and
available for issuance shall not be sufficient to permit conversion of the
Series A Preferred.

                  All shares of Common Stock which may be issued upon conversion
of the shares of Series A Preferred will upon issuance by the Corporation be
duly and validly issued, fully paid and nonassessable and free from all taxes,
liens and charges with respect to the issuance thereof and the Corporation shall
take no action which will cause a contrary result.

                  The rights, preferences, privileges and restrictions granted
to or imposed upon the Series A Preferred and the Common Stock or the holders
thereof are as follows:

A.       SERIES A CONVERTIBLE PREFERRED STOCK

                  Section 1. Dividends. No dividends shall accrue on the Series
A Preferred. The holders of the Series A Preferred shall be entitled to receive,
out of funds legally available therefor, dividends at the same rate as dividends
are paid with respect to the Common Stock (treating each share of Series A
Preferred as being equal to the number of shares of Common Stock (including
fractions of a share) into which each share of Series A Preferred is then
convertible). All numbers relating to the calculation of dividends shall be
subject to equitable adjustment in the event of any stock dividend, stock split,
combination, reorganization, recapitalization, reclassification or other similar
event involving a change in the capital structure of the Series A Preferred.

                                       2
<PAGE>   3
                  Section 2. Liquidation Preference. Subject to Section 2(d)
hereof, in the event of a Liquidity Event (as hereinafter defined), before any
distribution or payment may be made with respect to the Common Stock or any
other series or class of capital stock ranking on liquidation junior to the
Series A Preferred, holders of each share of Series A Preferred at each holders
sole option shall be entitled to be paid first out of the assets of the
Corporation available for distribution to holders of the Corporation's capital
stock of all classes, whether such assets are capital, surplus, or capital
earnings, as follows:

                  (a) The holders of the Series A Preferred shall be entitled to
receive at each holders sole option, prior and in preference to any distribution
of any of the assets or surplus funds of the Corporation to the holders of the
Common Stock, by reason of their ownership of such stock, the amount equal to
the sum of $4.91 per share for each share of Series A Preferred (as adjusted for
any stock splits, stock dividends, combinations, recapitalizations,
reclassifications or other similar events involving a change in the capital
structure of the Series A Preferred) plus any dividends declared but unpaid on
such share (the "Liquidation Amount"), plus an additional amount equal to 8% per
annum on the Liquidation Amount accrued from the date of issuance of each such
share of Series A Preferred to the date of payment of the Liquidation Amount
(together with the Liquidation Amount, the "Liquidation Preference. If the
assets of the Corporation legally available for distribution to the holders of
the Series A Preferred are insufficient to permit payment of the Liquidation
Preference Amount in full to all holders of Series A Preferred, the holders of
the Series A Preferred shall share ratably in any distribution of available
assets to the holders of Series A Preferred pro rata in proportion to the
respective Liquidation Preference Amounts each such holder would otherwise be
entitled to receive if all Liquidation Preference Amounts with respect to such
shares were paid in full.

                  (b) After payment has been made to the holders of the Series A
Preferred of the full amounts to which they shall be entitled as set forth in
Section 2(a), then the entire remaining assets and funds of the Corporation
legally available for distribution, if any, shall be distributed on a pro rata
basis on the outstanding Common Stock.

                  (c) For purposes of this Section 2, the term "Liquidity Event"
shall mean any one or more of the following: (i) a liquidation, dissolution or
winding-up of the Corporation, whether voluntary or involuntary; (ii) a sale of
all or substantially all of the assets of the Corporation, or a merger or
consolidation of the Corporation with or into any other entity in which the
aggregate Transaction Value (as hereinafter defined) is less than or equal to
$143,000,000 (other than a merger or consolidation in which shares of the
Corporation's voting capital interests outstanding immediately before such
merger or consolidation are exchanged or converted into or constitute shares
which represent more than fifty percent (50%) of the surviving entity's voting
capital interests after such consolidation or merger) or (iii) a transaction or
series of related transactions in which a person or group of persons (as defined
in Rule 13d-5(b)(1) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) acquires beneficial ownership (as determined in accordance with
Rule 13d-3 of the Exchange Act) of more than 50% of the 

                                       3
<PAGE>   4
voting power of the Corporation (the Liquidity Events described in (ii) and
(iii) of this clause are collectively, the "Sale Transaction Liquidity Events");
provided, however, that any reorganization, merger or consolidation involving
(1) only a change in the state of incorporation of the Corporation, (2) a merger
of the Corporation with or into a wholly-owned subsidiary of the Corporation
that is incorporated in the United States of America, or (3) an acquisition by
merger, reorganization or consolidation, of which the Corporation is
substantively the surviving corporation and operates as a going concern, of
another entity or corporation incorporated in the United States of America that
is engaged in a business similar or related to the business of the Corporation
and which does not involve a recapitalization or conversion of the Series A
Preferred shall not constitute a "Sale Transaction Liquidity Event".

                  (d) Notwithstanding the foregoing, in the event of a Sale
Transaction Liquidity Event in which the aggregate Transaction Value is greater
than $143,000,000 (subject to the provisos set forth in Section 2(c) herein),
the holders of Series A Preferred shall be entitled to receive their pro rata
share of the assets or proceeds, as the case may be, as if they had converted
their shares of Series A Preferred into Common Stock immediately prior to such
transaction at the then applicable Conversion Price pursuant to the provisions
of Section 4 hereof.

                  (e) For purposes of this Section 2, the term "Transaction
Value" with respect to any transaction, shall mean the amount of consideration
actually received (x) by the shareholders of the Corporation and (y) by the
Corporation, in each case, with respect to such transaction; provided, however,
that such aggregate consideration shall not be deemed to include (i) amounts
received by the holders of options, warrants and convertible securities which
are not exercisable at the time of or upon consummation of such transaction (ii)
the amount of any indebtedness for borrowed money set forth on the consolidated
balance sheet of the Corporation and its subsidiaries as of the last fiscal
quarter prior to the consummation of such transaction) or balance sheet, if any,
prepared in connection with such transaction, or (iii) contingent payments to
the Corporation or its shareholders (including but not limited to "earnouts")
and which, in the case of (i), (ii) and (iii), are assumed by the purchaser or
an affiliate in such transaction.

                  Section 3.  Redemption.

                  (a) Within thirty days following the written request (the
"Redemption Request") of a majority in interest of the holders of the Series A
Preferred, which Redemption Request may be given at any time on or after the
seventh anniversary of the date of initial issuance of Series A Preferred (the
"Redemption Date"), the Corporation shall redeem the Series A Preferred by
paying in cash therefor, $4.91 per share of Series A Preferred (as adjusted for
any stock splits, stock dividends, combinations, recapitalizations,
reclassifications or other similar events involving a change in the capital
structure of the Series A Preferred) plus all declared but unpaid dividends on
such shares (the "Redemption Price").

                  (b) At least ten (10) but no more than twenty (20) days prior
to the Redemption Date written notice shall be mailed, first class postage
prepaid, to each 

                                       4
<PAGE>   5
holder of the Series A Preferred at the address set forth in the records of the
Corporation, notifying such holder of the place at which payment may be obtained
on the Redemption Date for the shares of Series A Preferred and calling upon
such holder to surrender to the Corporation, in the manner and at the place
designated, such holder's certificate or certificates representing the shares to
be redeemed (the "Redemption Notice"). On or after the Redemption Date, each
holder of Series A Preferred shall surrender to the Corporation the certificate
or certificates representing such shares, in the manner and at the place
designated in the Redemption Notice, and thereupon the Redemption Price of such
shares shall be payable to the order of the person whose name appears on such
certificate or certificates as the owner thereof and each surrendered
certificate shall be canceled.

                  (c) From and after the Redemption Date, unless there shall
have been a default in payment of the Redemption Price, all rights of the
holders of shares of Series A Preferred as holders of Series A Preferred (except
the right to receive the Redemption Price without interest upon surrender of
their certificate or certificates) shall cease with respect to such shares, and
such shares shall not thereafter be transferred on the books of the Corporation
or be deemed to be outstanding for any purpose whatsoever. If the funds of the
Corporation legally available for redemption of shares of Series A Preferred on
the Redemption Date are insufficient to redeem the total number of shares of
Series A Preferred, those funds which are legally available will be used to
redeem the maximum possible number of such shares ratably among the holders of
such shares to be redeemed based upon their holdings of Series A Preferred. The
shares of Series A Preferred not redeemed shall remain outstanding and entitled
to all the rights and preferences provided herein. At any time thereafter when
additional funds of the Corporation are legally available for the redemption of
shares of Series A Preferred such funds will immediately be used to redeem the
balance of the shares which the Corporation has become obliged to redeem on any
Redemption Date but which it has not redeemed.

                  Section 4. Conversion. The holders of the Series A Preferred
shall have conversion rights as follows (the "Conversion Rights"):

                  (a) Right to Convert Series A Preferred. Each share of Series
A Preferred shall be convertible, at the option of the holder thereof, at any
time after the date of issuance of such share, at the office of the Corporation
or any transfer agent for the Series A Preferred, into such number of fully paid
and nonassessable shares of Common Stock as is determined by multiplying each
share of Series A Preferred by the quotient obtained by dividing $4.91 by the
then applicable Series A Conversion Price. The price at which shares of Common
Stock shall be deliverable upon conversion of the Series A Preferred (the
"Series A Conversion Price") shall initially be $4.91 per share of Common Stock.
Such initial Series A Conversion Price shall be subject to adjustment as
hereinafter provided.

                  (b) Automatic Conversion of Series A Preferred. Each share of
the Series A Preferred shall automatically be converted into shares of Common
Stock at the then effective Series A Conversion Price, immediately prior to the
effectiveness of a Qualifying Public Offering (as hereinafter defined) at the
then applicable Series A 

                                       5
<PAGE>   6
Conversion Price. For purposes of this Section 4, the term "Qualifying Public
Offering" shall mean a firm commitment underwritten public offering of Common
Stock by the Corporation with a nationally recognized investment banking firm,
which results in gross proceeds to the Corporation equal to or greater than
$30,000,000 and in which the pre-money valuation of the Corporation immediately
prior to such offering is equal to or greater than $ 150,000,000. The automatic
conversion of the Series A Preferred into shares of Common Stock shall be
subject in all circumstances to the closing and consummation of the offer and
sale of shares of Common Stock in a Qualified Public Offering.

                  (c) Mechanics of Conversion. No fractional shares of Common
Stock shall be issued upon conversion of the Series A Preferred. In lieu of any
fractional share to which the holder would otherwise be entitled, the
Corporation shall (after aggregating all shares into which shares of Series A
Preferred held by each holder could be converted) pay cash equal to such
fraction multiplied by the market price per share of Common Stock (as determined
in a reasonable manner presented by the Board of Directors) at the close of
business on the date of conversion. Before any holder of Series A Preferred
shall be entitled to convert the same into full shares of Common Stock and to
receive certificates therefor, the holder shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of any
transfer agent, and shall give written notice to the Corporation at such office
that the holder elects to convert all or any number of shares of the Series A
Preferred represented by such certificate or certificates, provided, however,
that in the event of an automatic conversion pursuant to clause (b) of this
Section 4, the outstanding shares of Series A Preferred shall be converted
automatically without any further action by the holders of such shares and
whether or not the certificates representing such shares are surrendered to the
Corporation or its transfer agent, and provided further, that the Corporation
shall not be obligated to issue certificates evidencing the shares of Common
Stock issuable upon such automatic conversion unless the certificates evidencing
such shares of Series A Preferred are either delivered to the Corporation or its
transfer agent as provided above, or the holder notifies the Corporation or its
transfer agent that such certificates have been lost, stolen or destroyed and
executes an agreement satisfactory to the Corporation to indemnify the
Corporation from any loss incurred by it in connection with such certificates.
The Corporation shall, as soon as practicable after such delivery, or such
agreement and indemnification in the case of a lost certificate, issue and
deliver at the office of the Corporation or of any transfer agent, as the case
may be, to such holder of Series A Preferred, a certificate or certificates for
the number of shares of Common Stock to which the holder shall be entitled as
aforesaid and a check payable to the holder in the amount of any cash amounts
payable as the result of a conversion into a fractional share of Common Stock.
Such conversion shall not terminate the rights of the holders of the Series A
Preferred or Common Stock issuable upon conversion of the Series A Preferred to
receive dividends which have been declared but are unpaid with respect to the
Series A Preferred prior to the date of conversion. Except as provided above,
such conversion shall be deemed to have been made immediately prior to the close
of business on the date of such surrender of the shares of Series A Preferred to
be converted, or in the case of automatic conversion immediately prior to the
close of business on the date of closing of a Qualifying Public Offering, and
the person or persons entitled to receive the shares of 

                                       6
<PAGE>   7
Common Stock issuable upon such conversion shall be treated for all purposes as
the record holder or holders of such shares of Common Stock at the close of
business on such date.

         (d) Series A Preferred Conversion Price Adjustments. The Series A
Conversion Price shall be subject to adjustment upon the issuance of Additional
Shares of Common Stock from time to time as follows:

                  (i) Special Definitions. For purposes of this Section 4(d),
the following definitions shall apply:

                      (1) "Options" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities.

                      (2) "Original Issue Date" shall mean the date on which the
first share of Series A Preferred was first issued.

                      (3) "Convertible Securities" shall mean any evidences of
indebtedness, shares (other than Common Stock and Series A Preferred) or other
securities convertible into or exchangeable for Common Stock.

                      (4) "Conversion Price" shall be the Series A Conversion 
Price.

                      (5) "Additional Shares of Common Stock" shall mean all 
shares of Common Stock issued (or, pursuant to Section 4(d)(iii) below, deemed
to be issued) by the Corporation after the Original Issue Date other than shares
of Common Stock issued or issuable:

                           (A) in an amount not exceeding 1,500,000 shares of
Common Stock to officers, directors and employees of, and consultants and
vendors to the Corporation or any subsidiary thereof, pursuant to a stock option
plan, stock purchase plan or other employee stock incentive plan approved by the
Board of Directors or other stock arrangements which have been approved by the
Board of Directors at prices or exercise prices determined by the Board of
Directors to be not less than the fair market value of such shares, options or
other stock arrangements on the date of grant thereof;

                           (B) upon conversion of shares of the Series A
Preferred or the exercise or conversion of any Options outstanding on the
Original Issue Date;

                           (C) pursuant to any event for which adjustment has
already been made pursuant to this Section 4(d);

                           (D) as a dividend or distribution on the Series A
Preferred;

                                       7
<PAGE>   8

                           (E) as a dividend or distribution on the Common
Stock;

                           (F) upon any subdivision or split up of Common Stock;

                           (G) upon any capital reorganization of the
Corporation; or

                           (H) up to an aggregate of 9,214,344 shares as all or
a portion of the consideration for acquisitions by the Corporation pursuant to
the Corporation's acquisition strategy in effect on the Original Issue Date.

                  (ii) No Adjustment of Conversion Price. No adjustment in the
Conversion Price shall be made in respect of the issuance of Additional Shares
of Common Stock unless the consideration per share for an Additional Share of
Common Stock issued or deemed to be issued by the Corporation is less than the
Conversion Price, in effect on the date of and immediately prior to such issue.

                  (iii) Deemed Issue of Additional Shares of Common Stock.
Except as provided in Section 4(d)(i)(5) above, in the event the Corporation at
any time or from time to time after the Original Issue Date shall issue any
Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such a record date shall have been fixed, as
of the close of business on such record date, provided that Additional Shares of
Common Stock shall not be deemed to have been issued unless the consideration
per share (determined pursuant to Section 4(g)(v) below) of such Additional
Shares of Common Stock would be less than the Conversion Price in effect on the
date of and immediately prior to such issue, or such record date, as the case
may be, and provided further that in any such case in which Additional Shares of
Common Stock are deemed to be issued:

                           (1) no further adjustment in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                           (2) if such Options or Convertible Securities by
their terms provide, with the passage of time or otherwise, for any increase or
decrease in the consideration payable to the Corporation, or increase or
decrease in the number of shares of Common Stock issuable, upon the exercise,
conversion or exchange thereof, the Conversion Price computed upon the initial
Conversion Price thereof set forth in Section 

                                       8
<PAGE>   9
4(a) above (or upon the occurrence of a record date with respect thereto), and
any subsequent adjustments based thereon, shall, upon any such increase or
decrease becoming effective, be recomputed to reflect such increase or decrease
insofar as it affects such Options or the rights of conversion or exchange under
such Convertible Securities;

                                    (3) on the expiration or cancellation of any
Options or the termination of the right to convert or exchange any Convertible
Securities which shall have not been exercised, if the Conversion Price shall
have been adjusted upon the original issuance thereof or shall have been
subsequently adjusted pursuant to clause (2) above, the Conversion Price shall
be recomputed as if the only Additional Shares of Common Stock issued were
shares of Common Stock, if any, actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities and the
consideration received therefore was the consideration actually received by the
Corporation for the issue of all such Options, whether or not exercised, plus
the consideration actually received by the Corporation upon such exercise, or
for the issue of all such Convertible Securities which were actually converted
or exchanged plus the consideration actually received by the Corporation upon
such conversion or exchange, if any; and

                                    (4) no readjustment pursuant to clause (2)
or clause (3) above shall have the effect of increasing the Conversion Price to
an amount which exceeds the lower of (i) the initial Conversion Price on the
original adjustment date (unless the Conversion Price is increased above the
initial Conversion Price pursuant to Section 4(e)(2) or (e)(4)), or (ii) the
Conversion Price that would have resulted from any issuances of Additional
Shares of Common Stock (other than those the subject of such adjustments)
between the original adjustment date and such readjustment date; and

                           (iv) Adjustment of Conversion Price Upon Issuance of
Additional Shares of Common Stock. In the event this Corporation shall issue
Additional Shares of Common Stock (including Additional Shares of Common Stock
deemed to be issued pursuant to Section 4(d)(iii), but excluding stock
dividends, subdivisions or split-ups that are the subject of adjustment pursuant
to Section 4(e)) without consideration or for a consideration per share less
than the Conversion Price applicable on and immediately prior to such issue,
then and in such event, the Conversion Price shall be reduced concurrently with
such issue, to a price (calculated to the nearest cent) determined by
multiplying the Conversion Price in effect on the date of and immediately prior
to such issue by a fraction, the numerator of which shall be the sum of (i) the
number of shares of Common Stock outstanding immediately prior to such issue (on
a fully diluted as converted basis), including without limitation the number of
shares of Common Stock issuable upon conversion of the Series A Preferred
outstanding immediately prior to such issue and (ii) the number of shares of
Common Stock which the aggregate consideration received by the Corporation for
the total number of Additional Shares of Common Stock so issued would purchase
at the Conversion Price in effect on the date of and immediately prior to such
issue; and the denominator of which shall be the sum of (i) the number of shares
of Common Stock outstanding immediately prior to such issue (on a fully diluted
as converted basis), including without limitation the


                                       9
<PAGE>   10
number of shares of Common Stock issuable upon conversion of the Series A
Preferred outstanding immediately prior to such issue and (ii) the number of
such Additional Shares of Common Stock so issued.

                           (v) Determination of Consideration. For purposes of
this Section 4(g), the consideration received by the Corporation for the issue
of any Additional Shares of Common Stock shall be computed as follows:

                                    (1) Cash and Property. Such consideration
shall:

                                            (A) insofar as it consists of cash,
be computed at the aggregate amount of cash received by the Corporation;

                                            (B) insofar as it consists of
property other than cash, be computed at the fair value thereof at the time of
such issue, as determined in good faith by the Board of Directors; and

                                            (C) in the event Additional Shares
of Common Stock are issued together with other shares or securities or other
assets of the Corporation for consideration which covers both, be the proportion
of such consideration so received, computed as provided in clauses (A) and (B)
above, as determined in good faith by the Board of Directors.

                                    (2) Options and Convertible Securities. The
consideration per share received by the Corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 4(d)(ii) and
4(d)(iii), relating to Options and Convertible Securities, shall be determined
by dividing:

                                            (A) the total amount, if any,
received or receivable by the Corporation as consideration for the issue of such
Options or Convertible Securities, plus the (ii) aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration) payable to the Corporation upon the exercise of such Options or
the conversion or exchange of such Convertible Securities, or in the case of
Options for Convertible Securities, the exercise of such options for Convertible
Securities and the conversion or exchange of such Convertible Securities by

                                            (B) the maximum number of shares of
Common Stock (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such number)
issuable upon the exercise of such Options or the conversion or exchange of such
Convertible Securities.

                  (e) Adjustment of Conversion Price of Series A Preferred. The
Series A Conversion Price shall be subject to adjustment from time to time as
follows:

                           (1) Adjustments for Subdivisions of Common Stock. If
the number of shares of Common Stock outstanding at any time after filing this
Certificate of Amendment to Certificate of Incorporation with the Secretary of
State of the State of


                                       10
<PAGE>   11
Delaware is increased by a stock dividend payable in shares of Common Stock or
by a subdivision or split up of stock, then the Series A Conversion Price then
in effect shall, concurrently with the effectiveness of such dividend,
subdivision or split up, be proportionately decreased so that the number of
shares of Common Stock issuable on conversion of each share of Series A
Preferred shall be increased in proportion to such increase of outstanding
shares of Common Stock.

                           (2) Adjustments for Combinations of Common Stock. If
the number of shares of Common Stock outstanding at any time after filing this
Certificate of Amendment to Certificate of Incorporation with the Secretary of
State of the State of Delaware is decreased by a combination of the outstanding
shares of Common Stock, then the Series A Conversion Price then in effect shall,
concurrently with the effectiveness of such combination, be proportionately
increased so that the number of shares of Common Stock issuable upon conversion
of each share of Series A Preferred shall be decreased in proportion to such
decrease in outstanding shares of Common Stock.

                           (3) Adjustments for Stock Dividends and Other
Distributions. In the event the Corporation at any time or from time to time
makes or fixes a record date for the determination of holders of Common Stock
entitled to receive any distribution (excluding any repurchases of securities by
the Corporation not made on a pro rata basis from all holders of any class of
the Corporation's securities) payable in property or in securities of the
Corporation other than shares of Common Stock, then and in each such event the
holders of Series A Preferred shall receive at the time of such distribution,
the amount of property or the number of securities of the Corporation that they
would have received had their Series A Preferred been converted into Common
Stock on the date of such event.

                           (4) Adjustments for Reclassification, Exchange and
Substitution. Except as provided in Section 2 upon a Liquidity Event, if the
Common Stock issuable upon conversion of the Series A Preferred shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision or combination of shares provided for above), each share of
Series A Preferred shall thereafter be convertible into, in lieu of the number
of shares of Common Stock which the holders would otherwise have been entitled
to receive, a number of shares of such other class or classes of stock
equivalent to the number of shares of Common Stock that would have been subject
to receipt by the holders upon conversion of the Series A Preferred immediately
before that change. In addition, to the extent applicable in any reorganization
or recapitalization, provision shall be made so that the holders of the Series A
Preferred shall thereafter be entitled to receive upon conversion of the Series
A Preferred the number of shares of stock or other securities or property of the
Corporation or otherwise, to which a holder of Common Stock deliverable upon
conversion would have been entitled on such reorganization or recapitalization.

                  (f) Amendments to Certificate of Incorporation. The
Corporation shall not amend its Certificate of Incorporation without the
approval, by vote or written


                                       11
<PAGE>   12
consent, by the holders of at least 66 2/3% of the then outstanding shares of
Series A Preferred, voting together as a separate class, if such amendment would
(x) amend, alter or change any of the rights, preferences, privileges of or
limitations provided for herein for the benefit of any shares of Series A
Preferred, (y) increase or decrease (other than by redemption or conversion) the
authorized number of shares of Series A Preferred or (iii) create any new class
of equity securities having rights and preferences senior to or on a parity with
the Series A Preferred with respect to voting, dividends or liquidation
preference.

                  (g) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Series A Conversion Price pursuant to Section
4(d), the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Series A Preferred a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based. The Corporation shall, upon the written request at any time of any holder
of Series A Preferred, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Series A Conversion Price at the time in effect, and (iii) the number of shares
of Common Stock and the amount, if any, of other property which at the time
would be received upon the conversion of Series A Preferred. Notwithstanding the
foregoing, no adjustment of the Series A Conversion Price shall be made if the
amount of any such adjustment would be an amount less than $1.00, but any such
amount shall be carried forward and an adjustment with respect thereof shall be
made at the time of and together with any subsequent adjustment which, together
with such amount and any other amount(s) so carried forward, shall aggregate an
increase or decrease of $1.00 or more.

                  (h) Notices of Record Date. In the event that the Corporation
shall propose at any time:

                           (i) to declare any dividend or distribution upon its
Common Stock, whether in cash, property, stock or other securities, whether or
not a regular cash dividend and whether or not out of earnings or earned
surplus;

                           (ii) to offer for subscription pro rata to the
holders of any class or series of its stock any additional shares of stock of
any class or series or other rights;

                           (iii) to effect any reclassification or
recapitalization of its Common Stock outstanding involving a change in the
Common Stock; or

                           (iv) to merge or consolidate with or into any other
corporation, or sell, lease or convey all or substantially ail its property or
business, or to liquidate, dissolve or wind up;

then, in connection with each such event, the Corporation shall send to the
holders of the Series A Preferred:

                                       12
<PAGE>   13
                                    (1) at least twenty (20) days' prior written
notice of the date on which a record shall be taken for such dividend,
distribution or subscription rights (and specifying the date on which the
holders of Common Stock shall be entitled thereto) or for determining rights to
vote in respect of the matters referred to in (iii) and (iv) above; and

                                    (2) in the case of the matters referred to
in (iii) and (iv) above, at least twenty (20) days' prior written notice of the
date when the same shall take place (and specifying the date on which the
holders of Common Stock shall be entitled to exchange their Common Stock for
securities or other property deliverable upon the occurrence of such event).

                  Each such written notice shall be delivered personally or
given by first class mail, postage prepaid, addressed to the holders of Series A
Preferred at the address for each such holder as shown on the books of the
Corporation.

                  Section 5. Voting. Except as may be otherwise provided in
these terms of the Series A Preferred or by law, the Series A Preferred shall
vote together with all other classes and series of voting stock of the
Corporation as a single class on all actions to be taken by the stockholders of
the Corporation. Each share of Series A Preferred shall entitle the holder
thereof to such number of votes per share on each such action as shall equal the
number of shares of Common Stock (including fractions of a share) into which
each share of Series A Preferred is then convertible pursuant to Section 4
hereof.

B.       COMMON STOCK

                  All shares of Common Stock will be identical and will entitle
the holders thereof to the same rights and privileges.

                  Section 1. Dividends. When, as and if dividends are declared
thereon, whether payable in cash, property or securities of the Corporation, the
holders of Common Stock will be entitled to share equally in and receive, in
accordance with the number of shares of Common Stock held by each such holder,
such dividends. Dividends payable under this Section 1 shall be paid to the
holders of record of the outstanding Common Stock as their names shall appear on
the stock register of the Corporation on the record date fixed by the Board of
Directors in advance of declaration and payment of each dividend. Any Common
Stock issued as a dividend pursuant to this Section 1 shall, when so issued, be
duly authorized, validly issued, fully paid and non-assessable, and free of all
liens and charges.

                  Notwithstanding anything contained herein to the contrary, no
dividends on Common Stock shall be declared by the Corporation's Board of
Directors or paid or set apart for payment by the Corporation at any time that
such declaration, payment, or setting apart is prohibited by applicable law.

                  Section 2. Voting Rights. Each holder of the Common Stock
shall be entitled to one vote for each share of Common Stock held on all matters
submitted to a vote of the stockholders.

                  Section 3. Other Rights. Except for and subject to those
rights expressly granted to the holders of Series A Preferred, or as otherwise
provided herein, and except as may be provided by the laws of the State of
Delaware, the holders of Common Stock shall have exclusively all other rights of
stockholders, including, without limitation, (a) the right to receive dividends,
when, as and if declared by the Board of Directors, out of assets lawfully
available therefor, and (b) in the event of any distribution of assets upon a
liquidation, dissolution or winding up or otherwise, the right to receive
ratably and equally with all other holders of Common Stock all of the assets and
funds of the Corporation remaining after the payment to the holders of the
Series A Preferred, of the specific amounts which they are entitled to receive
upon such liquidation, dissolution or winding up. For the purposes of this
Section 3, neither the consolidation, combination or merger of the Corporation
with or into any other corporation or corporations in which the stockholders of
the Corporation receive cash or capital stock and/or other securities (including
debt securities) of the acquiring corporation (or of the direct or indirect
parent corporation of the acquiring corporation), nor the sale, lease, or
transfer by the Corporation of all or any part of its assets, nor the reduction
of the capital stock of the Corporation, shall be deemed to be a liquidation,
dissolution or winding up of the Corporation.

                  Subject to Section A.4(f) of this Paragraph Fourth, the Board
of Directors (or a duly authorized committee thereof) is hereby expressly

unissued shares of Preferred Stock, one or more series of Preferred Stock which
shall have the powers, terms, conditions, designations, preferences and
privileges, the relative, participating, optional and other special rights, and
the qualifications, limitations and restrictions, if any, as provided herein.
Before any shares of any such series are issued, the Board of Directors (or a
duly authorized committee thereof) shall fix, and is hereby expressly empowered
to fix, as to the shares of any such series:

                  (a) the designation of such series, the number of shares to
constitute such series and the stated value thereof, if different from the par
value thereof;

                  (b) whether the shares of such series shall have voting rights
or powers, in addition to any voting rights required by law and, if so, the
terms of such voting rights or powers, which may be full or limited;

                  (c) the dividends, if any, payable on such series, whether any
such dividends shall be cumulative and, if so, from what dates, the conditions
and dates upon which such dividends shall be payable, the preferences or
relation which such dividends shall bear to the dividends payable on any shares
of stock of any other class or any other series of this class;

                  (d) whether the shares of such series shall be subject to
redemption by the Corporation and, if so, the times, prices and other conditions
of such redemption;

                                       14
<PAGE>   15
                  (e) the amount or amounts payable upon shares of such series
upon, and the rights of the holders of such series in, the liquidation,
dissolution or winding up, or upon any distribution of the assets, of the
Corporation;

                  (f) whether the shares of such series shall be subject to the
operation of a retirement or sinking fund and, if so, the extent to which and
manner in which any such retirement or sinking fund shall be applied to the
purchase or redemption of the shares of such series for retirement or other
corporate purposes and the terms and provisions relative to the operation
thereof;

                  (g) whether the shares of such series shall be convertible
into or exchangeable for shares of stock of any other class or any other series
of this class or any other securities and, if so, the price or prices or the
rate or rates of conversion or exchange and the method, if any, of adjusting the
same, and any other terms and conditions of conversion or exchange;

                  (h) the limitations and restrictions, if any, to be effective
while any shares of such series are outstanding upon the payment of dividends or
the making of other distributions on, and upon the purchase, redemption or other
acquisition by the Corporation of, the Common Stock or shares of stock of any
other class or any other series of this class;

                  (i) the conditions or restrictions, if any, to be effective
while any shares of such series are outstanding upon the creation of
indebtedness of the Corporation or upon the issue of any additional stock,
including additional shares of such series or of any other series of this class
or of any other class; and

                  (j) any other powers, designations, preferences and relative,
participating, optional or other special rights, and any qualifications,
limitations, or restrictions thereof.

                   The powers, designations, preferences and relative,
participating, optional or other special rights of each series of Preferred
Stock, and the qualifications, limitations or restrictions thereof, if any, may
differ from those of any and all other series at any time outstanding. The Board
of Directors is hereby expressly authorized from time to time to increase (but
not above the total number of shares thereof then outstanding) the number of
shares of Preferred Stock designated to any one or more series of Preferred
Stock pursuant to this Section C of this Paragraph Fourth.

                  Fifth: A. Board of Directors. The number of directors of the
Corporation shall consist of not less than five (5) nor more than fifteen (15)
directors. The exact number of directors shall be determined from time to time
by a resolution or resolutions adopted by the affirmative vote of a majority of
the total number of directors which the Corporation would have if there were no
vacancies or by resolution adopted by the stockholders. Directors (whether
elected at an annual meeting or to fill a vacancy or otherwise) shall hold
office for a term expiring at the next annual meeting of stockholders


                                       15
<PAGE>   16
of the Corporation, at which meeting their successors will be elected. Directors
shall hold office until their successors are duly elected and qualified,
subject, however, to a director's prior death, resignation, disqualification or
removal from office. Any additional director elected to fill a vacancy resulting
from an increase in the number of directors shall hold office for a term that
shall coincide with the remaining term of the existing directors, but in no case
shall a decrease in the number of directors shorten the term of any incumbent
directors.

                  B. Removal of Directors. A director may be removed from
office, either with or without cause, by the affirmative vote of the holders of
a majority of the combined voting power of all outstanding shares of stock then
entitled to vote generally in the election of directors, voting as a single
class.

                  Sixth: The following provisions are inserted for the
management of the business and for the conduct of the affairs of the
Corporation, and in furtherance and, except as specifically set forth in this
Paragraph, not in limitation of the powers of the Corporation and of its
directors and stockholders conferred by statute:

                  (1) Subject to the provisions of Paragraph Eleventh hereof,
the Board of Directors shall have power without (except as provided by
applicable law) the assent or vote of the stockholders to make, alter, amend,
change, add to or repeal the By-laws of the Corporation; to authorize and cause
to be executed mortgages and liens upon all or any part of the property of the
Corporation; to determine the use and disposition of any surplus or net profits;
to fix the times for the declaration and payment of dividends; and to set apart
out of any of the funds of the Corporation available for dividends a reserve or
reserves for any proper purpose and to abolish any such reserve.

                  (2) In addition to the powers and authorities hereinbefore or
by statute expressly conferred upon them, the Board of Directors is hereby
empowered to exercise all such powers and do all such acts and things as may be
exercised or done by the Corporation; subject, nevertheless, to the provisions
of the laws of the state of Delaware, this Amended and Restated Certificate of
Incorporation and the Corporation's By-laws, as in effect from time to time.

                  SEVENTH: The books and records of the Corporation may be kept
(subject to any mandatory requirement of law) outside the State of Delaware at
such place or places as may be designated from time to time by the Board of
Directors or by the By-laws of the Corporation.

                  EIGHTH: No director shall be liable to the Corporation or any
of its stockholders for monetary damages for breach of fiduciary duty as a
director, provided that the foregoing does not eliminate or limit any liability
that may exist with respect to (1) a breach of the director's duty of loyalty to
the Corporation or its stockholders, (2) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (3)
liability under Section 174 of the DGCL or (4) a transaction from which the
director derived an improper personal benefit, it being the intention of the
foregoing provision to eliminate the liability of the Corporation's directors to
the


                                       16
<PAGE>   17
Corporation or its stockholders to the fullest extent permitted by Section
102(b)(7) of the DGCL, as in effect on the date hereof and as such Section may
be amended after the date hereof to the extent such amendment permits such
liability to be further eliminated or limited. No amendment, modification or
repeal of this Paragraph Eighth shall adversely affect any right or protection
of a director that exists at the time of such amendment, modification or repeal.

                  NINTH: Subject to the provisions of Section A.4(f) of
Paragraph Fourth, the Corporation reserves the right to amend or repeal any
provision contained in this Amended and Restated Certificate of Incorporation in
the manner now or hereafter prescribed by the laws of the State of Delaware, and
all rights herein conferred upon stockholders or directors are granted subject
to this reservation.

                  TENTH: Following the consummation of an initial public
offering of Common Stock or any transaction or event as a result of which any
Common Stock is listed on a national securities exchange or registered under
Section 12 of the Securities Exchange Act of 1934, as amended, any action
required or permitted to be taken by the stockholders of the Corporation must be
affected at a duly called annual or special meeting of stockholders of the
Corporation, or by a consent in writing to the taking of such action if
provision for such consent is made in the Corporation's By-laws.

                  ELEVENTH: In furtherance and not in limitation of the power
conferred upon the Board of Directors by law, the Board of Directors shall have
the power to make, adopt, alter, amend and repeal from time to time the By-laws
of the Corporation, subject to the right of the stockholders entitled to vote
with respect thereto to alter, amend and repeal By-laws adopted by the Board of
Directors.

                   3. This Amended and Restated Certificate of Incorporation was
   duly adopted in accordance with the provisions of Sections 242 and 245 of the
   DGCL. The Board of Directors adopted resolutions setting forth this Amended
   and Restated Certificate of Incorporation, declaring its advisability and
   directing its consideration by the stockholders of the Corporation. A
   majority of the stockholders of the Corporation duly approved this Amended
   and Restated Certificate of Incorporation in accordance with Section 242 of
   the DGCL by executing a Waiver of Meeting of Stockholders and Majority
   Written Consent to Adoption of Resolutions pursuant to Section 228 of the
   DGCL, and written notice of such consent has been given to all stockholders
   who have not consented in writing to said amendments.

                                   SCHEDULE B
                               SAGE NETWORKS, INC.
                     CORPORATE TRAVEL AND ENTERTAINMENT POLICY

                         Policy Dated: February 16, 1999

General Policy

It is Sage's policy to reimburse employees for actual, reasonable and proper
business expenditures that are incurred while conducting authorized business for
Sage and that meet IRS regulations as a business expense. Managers are
responsible for ensuring that employees who incur travel or entertainment
expenses comply with the guidelines in this policy. Employees traveling on
corporate business are expected to exercise good judgement, ensure that
expenditures incurred are reasonable, necessary and in the best interest of the
Company and are within the guidelines of this policy.

Scope

All Sage employees.

Procedures

It is the responsibility of each manager reviewing and approving expense reports
to ensure that reported expenses are in accordance with these policies, and
properly documented. Reimbursement of reported expenses are subject to audit by
Sage and the IRS to ensure compliance with this policy and Internal Revenue
Service regulations.

Fraudulent entries on expense reports are considered cause for immediate
dismissal.

A.    Expense Reporting/Processing

- -    All employees should use the standard Sage expense report form for
     reporting expenses. An electronic version is available as an excel
     spreadsheet.

- -    Receipts are required for all expenses.

- -    Purpose of the trip (if applicable), should be noted on the expense report.

- -    Expenses must be itemized in the appropriate columns. Include the business
     purpose, name of restaurant and name of attendees and affiliation for all
     business meals with two or more people, in the description column of the
     expense report.

- -    Employees submitting more than one expense report should be sure that the
     receipts related to each report are attached to the appropriate report.

- -    Completed expense reports should be submitted to the employee's direct
     supervisor for approval. It is the responsibility of the manager to REVIEW
     the expense report before approving. The report should then be submitted to
     the Finance Department for
<PAGE>   7
     processing. All properly approved expense reports received by 12 noon on
     Friday will be processed by Finance by the following Friday, if not sooner.

- -    Expense reports are to be submitted to the employee's direct supervisor for
     approval within one week of completion of travel. Expense reports received
     more than 60 days after the expense is incurred will not be reimbursed.

- -    Unusual items not specifically approved by the Controller or COO will be
     questioned via e-mail requesting an explanation of the item from the
     employee. The employee's expense report will not be processed until the
     unusual items are satisfactorily explained.

B.    Lost Receipts

- -    If an employee loses a receipt for airline tickets, hotel charges or rental
     cars, the vendor can usually provide detailed copies of receipts. For
     expenses paid in cash or lost receipts, a letter from the employee's
     supervisor authorizing payment without receipt must be attached to the
     expense report.

C.    Travel Authorization

- -    All travel must be approved IN ADVANCE by the employee's direct supervisor.
     This should be done using the Company's Travel Authorization Form and
     should indicate all options researched (i.e., flights, Saturday stay,
     etc.). All approved Travel Authorization Forms should be forwarded to the
     Finance Department. Expenses incurred without proper approval will not be
     reimbursed.

- -    Employees must make all of their own travel arrangements through Vista
     Travel Agency, the Company's travel agency. Vista has negotiated corporate
     air, hotel and car rental rates for the Company, which may not be available
     if these providers are contacted directly. Expenses related to travel
     arrangements not made through Vista may not reimbursable unless
     documentation can be provided indicating that lower prices can be obtained
     elsewhere.

- -    Vista can be reached at (617) 621-0100 in MA or (800) 875-0100 out of MA,
     ask for Sharon McHugh (x230), who is the agent handling Sage's account.
     Vista's office manager is Jan Daubenspeck (x223) if Sharon is not
     available. After hours or in emergencies, employees can call (800)
     676-0371.

D.    Air Travel

- -    Whenever possible, reservations for travel should be made at least 7 days
     in advance of a trip in order to take advantage of the lowest possible
     airfares. Employees should evaluate the likelihood of changing plans before
     booking a penalty fare.

- -    Vista has been instructed to find Sage employees the lowest airfare
     possible, including fares that require connections or plane changes. The
     travel agency has been instructed to call the COO or Controller to approve
     the selection of a more expensive flight by an employee. The employee must
     provide the COO or Controller with a valid business need for the approval
     of the more expensive flight.
<PAGE>   8
- -    From time to time, the Company may require that employees travel with a
     particular airline with which it has negotiated special rates.

- -    All air travel should be coach class, except for international flights of
     more than six hours, in which case business class is allowed.

- -    Employees can use their own frequent flyer mileage to upgrade their
     seating, however they cannot select a higher priced flight in order to be
     able to upgrade their seat.

- -    Employees may retain any frequent flyer miles earned while traveling on
     company business. However, participation in these programs may not result
     in any incremental costs to the Company when selecting a flight.

- -    No more than five employees may travel on the same flight.

E.    Ground Transportation

- -    Each employee should assess the cost of ground transportation (i.e., car
     rental vs. taxi) and choose the least expensive option.

- -    No private limousines are allowed. Public airport or hotel limousine
     services that are shared are acceptable. Reservations for these services
     should be made through the Company's travel agency. Again, Vista Travel
     Agency has negotiated corporate rates that may not be available if an
     employee calls the limousine service directly.

- -    When an employee's personal car is used for business travel, other than
     normal commuting, the Company will reimburse the employee at a rate of $.31
     cents/mile.

- -    Travel to and from the airport is reimbursable.

F.    Rental Cars

- -    Midsize cars are to be used in all cases unless more than four people are
     traveling together.

- -    Employees are expected to refuel rental cars before returning them to avoid
     excessive fuel charges by the rental agency.

- -    As most credit card companies provide collision coverage, this coverage
     should be waived to avoid unnecessary charges.

G.    Hotels

- -    All hotel reservations should be made through Vista Travel Agency to ensure
     the lowest available rates. Employees are expected to stay in moderately
     priced business class hotels or motels. From time to time, the Company may
     require that employees stay in a particular hotel with which it has
     negotiated special rates.

- -    If a reservation must be canceled, employees should call the travel agency
     as soon as possible at the phone number above or call the hotel directly to
     avoid unnecessary charges.

- -    In-room entertainment (movies, drinks, etc.) is not reimbursable.

H.    Meals
<PAGE>   9
- -    Reimbursable meals are limited to $45 per day in the following cities: New
     York, Chicago, Los Angeles, San Francisco and Boston. Reimbursable meals
     are limited to $35 per day in all other cities. These are maximum
     reimbursable costs. Actual costs should be submitted on expense reports and
     RECEIPTS ARE REQUIRED for reimbursement. Tear off tabs are not acceptable.

- -    Room service meals are reimbursable as long as they are within the above
     limits including any gratuities or service charges.

- -    Employee lunches are not reimbursable unless they are approved by the CEO
     or COO.

I.    Entertainment

- -    Entertainment expenses for clients or other business associates are
     reimbursable if the entertainment is the setting for the business meeting.
     An explanation of the business purpose, the location of the restaurant or
     establishment and the name of the attendees and their company affiliation
     should be indicated on the expense report.

J.    Recruiting

- -    Travel related to potential recruits must be approved in advance by the CEO
     or COO. The Company will reimburse the recruit's expenses in accordance
     with the above employee policy. All recruits must submit expense reports
     with receipts. The expense report must be approved by the department
     manager. Travel arrangements should be made through Vista Travel.

K.    Telephone

- -    Reasonable costs for phone call for business purposes are reimbursable.
     These include business calls made from hotel rooms or from home office
     sites.

- -    Cellular phone calls will not be reimbursed.

- -    Phone calls on airplanes are not reimbursable unless it is an emergency.

L.    Laundry

- -    Reasonable costs for laundry are reimbursable for trips that require the
     employee to be away from home for five consecutive days or more.

M.    Travelers Check Fees

- -    The Company will reimburse fees for travelers checks. A receipt should be
     submitted with the expense report.

N.    Unusual Items
<PAGE>   10
- -    Unusual expenses must have written approval by the department manager
     attached to the expense report. Unusual items include:

     -    An amount spent for a reimbursable item that exceeds the normal
          guidelines.

     -    An expenditure that is not normally considered a business expense.

O.    Non-Reimbursable Expenses

- -    Personal items and services purchased while traveling are not reimbursable.
     These items include, but are not limited to:

     -    Traffic Fines

     -    Loss of cash advance

     -    Toiletries

     -    Newspapers or magazines

     -    Medicine


P.    Overseas Conversion Rates

- -    All expenses should be reported in US dollars. All currency exchange
     receipts should be saved and used for conversion for actual foreign
     expenses. If an expense is charged on a credit card, the actual conversion
     rate should appear on the statement. This rate should be used for expense
     reimbursement. If a conversion rate cannot be established by these means,
     then the current rate as published in the Wall Street Journal may be used.

Q.    Questions Regarding Travel Policy

- -    Please refer questions regarding the Company's travel policy to your
     immediate supervisor or to the Finance Department.

first.

6.2 Support Services shall consist of (i) error correction and telephone support
provided during Portal's normal business hours to Licensee's technical support
contact concerning the installation and use of the then current release of the

charges a separate fee. Portal shall have no obligation to support (a) altered,
damaged or modified Portal Software (except as authorized by Portal or if such
modifications or customizations are performed by Portal Professional Services
Group during implementation) or any portion of the Portal Software incorporated
into other software, (b) Portal Software that is not the then current or
immediately previous sequential release, (c) problems caused by Licensee's
negligence, abuse, or misapplication, or use of the Portal Software other than

6.3 Portal may elect on sixty (60) days notice (i) effective on any Annual
Maintenance Fee payment date thereafter with respect to any particular Portal
Software, to change the Annual Maintenance Fee and support services terms for
that Portal Software to its then standard fees and terms and/or (ii) effective
on the third or any later Annual Maintenance Fee payment date with respect to
any particular Portal Software, not to provide Support Services to Licensee for
that Portal Software, in which cases Licensee may elect to forego further
Support Services and Annual Maintenance Fees for such Portal Software, whereupon
Portal shall refund Licensee any Support Services fees pro-rated for the balance
of the annual term.

6.4 Upon completion of the implementation of the Portal Software by Portal,
Portal will provide Licensee with a letter confirming that such installation of
the Portal Software was authorized and that Portal's maintenance, technical

7 TERMINATION

7.1 This Agreement commences on the Effective Date and will remain in force
until it is terminated.

7.2 Licensee may, upon thirty (30) days prior written notice to Portal,
terminate this Agreement. However, no such termination will entitle Licensee to
a refund of any portion of any monies which have been paid to Portal.

7.3 Portal may, by written notice to Licensee, terminate this Agreement if any
of the following events ("Termination Events") occur, provided that no such
termination will entitle Licensee to a refund of any portion of any monies which
have been paid to Portal;

7.3.1 Licensee is in breach of this Agreement in any material respect, which
breach, if capable of being cured, is not cured within thirty (30) days after

obligations under Section 3 above in any material respect;

7.3.2 Licensee terminates its business activities or becomes insolvent, admits
in writing to its inability to generally pay its debts as they mature, makes an

payment obligations hereunder and any such payments are not reasonably
susceptible to being reclaimed or refunded.

7.4 Termination will become effective immediately under Section 7.3.2 or on the
date set forth in the written notice of termination under Section 7.3.1 provided
such date is not less than thirty (30) days from delivery of said notice.
Termination of this Agreement will not affect the provisions regarding
Licensee's or Portal's treatment of Confidential Information, provisions
relating to the payments of amounts due, provisions limiting or disclaiming
Portal's liability, and/or provisions regarding applicable law, which provisions
will survive termination of this Agreement.

7.5 Upon termination, all licenses granted hereunder shall cease to be effective
and Licensee shall immediately cease all use of any affected Portal Software,
Documentation and Portal Confidential Information.

7.6 Within fourteen (14) days of the date of termination or discontinuance of

8 INDEMNIFICATION FOR INFRINGEMENT

8.1 Portal shall, at its expense defend or settle any claim, action or
allegation brought against Licensee that the Portal Software infringes any
patent, copyright, trade secret or other proprietary right of any third party,
and Portal will similarly indemnify and hold harmless Licensee from damages and
costs incurred by Licensee (including reasonable attorneys' fees and costs) as a
result of any such claims of infringement and shall pay any final judgment
awarded or settlements entered into; provided that Licensee gives prompt written
notice to Portal of any such claim, action or allegation of infringement and
gives Portal the authority to proceed as contemplated herein. Portal will have
the exclusive right to defend any such claim, action, or allegation and make
settlements thereof at its own discretion, and Licensee may not settle or
compromise such claim, action or allegation, except with prior written consent
of Portal. Licensee shall give such assistance and information as Portal may
reasonably require to settle or oppose such claims.

8.2 In the event any such infringement, claim, action, or allegation is brought
or threatened, Portal may, at its sole option and expense:

8.2.1 Procure for Licensee the right to continue use of the Portal Software or
the infringing portion thereof;

8.2.2 Modify, amend or replace the Portal Software or infringing part thereof
with other software which has substantially the same or better capabilities;

8.2.3 If neither of the foregoing is commercially practicable, Portal shall
refund the portion of the licensee fee specified on Schedule A related to the
infringing part thereof less one-forty-eighth (1/48) thereof for each month or
portion thereof that this Agreement has been in effect. In the event that such
refund is made, Licensee shall immediately cease using the infringing portion of
the Portal Software and will remove the same from its system and so certify to
Portal. By paying a refund in the manner herein contemplated Portal will be
released from any further obligation whatsoever to Licensee in connection with
the infringing part of the Portal Software. If, as a result of having terminated
its licenses with respect to any infringing Portal Software, Licensee is unable
to use any or all of the other components of the Portal Software licensed
hereunder, Licensee shall be permitted to terminate its licenses for those other
Portal Software components upon the same terms and conditions as applicable to
the infringing Portal Software Components set forth above.

8.3 THE FOREGOING OBLIGATIONS SHALL NOT APPLY TO THE EXTENT THE INFRINGEMENT
ARISES AS A RESULT OF MODIFICATIONS TO THE PORTAL SOFTWARE MADE BY ANY PARTY
OTHER THAN PORTAL OR PORTAL'S AUTHORIZED REPRESENTATIVE. THIS SECTION 8 STATES
THE ENTIRE LIABILITY OF PORTAL WITH RESPECT TO INFRINGEMENT OF ANY PATENT,
COPYRIGHT, TRADE SECRET OR OTHER PROPRIETARY RIGHT.

9 WARRANTY AND LIMITATION OF LIABILITY

9.1 Portal warrants to Licensee that the Portal Software will perform in
substantial accordance with the Documentation for a period of one hundred eighty
(180) days from the Effective Date. Portal represents and warrants that the
Portal Software is designated to be used prior to, during and after the calendar
year 2000 and that the Portal Software will operate during each such time period
without error relating to, or the product of, date data which references
different centuries or more than one century. If the Portal Software does not
perform as warranted, Portal shall undertake to correct the non-conforming part
of the Portal Software, or if correction is reasonably not possible, replace
such non-conforming part of the Portal Software free of charge. If neither of
the foregoing is commercially practicable, Portal shall refund the monies paid
by Licensee for that non-conforming part of the Portal Software. In the event
that such refund is made, Portal may amend Schedule A with respect to the
non-conforming part of the software program. The foregoing Year 2000 Warranty
shall not apply to the extent that the Portal Software is used or interfaced
with other software, data or operating systems which are not Year 2000 compliant
and it is reasonably established that such non-compliant software, data or
operating system is the source of the Year 2000 problem or if the Portal
Software has been modified in a manner not authorized by Portal. THE FOREGOING
ARE LICENSEE'S SOLE AND EXCLUSIVE REMEDIES FOR BREACH OF WARRANTY. The warranty
set forth above is made to and for the benefit of Licensee only and will be
enforceable against Portal only if:

9.1.1 The Portal Software has been properly installed and has been used at all
times in accordance with the Documentation and this Agreement;

9.1.2 All modifications, alterations or additions to the Portal Software, if
any, have been made using Portal Software Customization Tools provided by Portal
to Licensee; and

9.1.3 Licensee has not made or caused to be made modifications, alterations or
additions to the Portal Software that cause it to deviate from the
Documentation.

9.2 Except as set forth above, Portal makes no warranties, whether express or
implied, or statutory regarding or relating to the Portal Software or the
Documentation, or any materials or services furnished or provided to Licensee
under this Agreement. Specifically, Portal does not warrant that the Portal
Software will be error free or will perform in an uninterrupted manner. To the
maximum extent allowed by law, Portal specifically disclaims all implied
warranties of merchantability and fitness for a particular purpose (even if
Portal had been informed of such purpose) with respect to the Portal Software,
Documentation and support and with respect to the use of any of the foregoing.

9.3 IN NO EVENT WILL PORTAL OR ITS SUBCONTRACTORS BE LIABLE FOR ANY LOSS OF
PROFITS, LOSS OF USE, BUSINESS INTERRUPTION, LOSS OF DATA, COST OF COVER OR
INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND IN CONNECTION
WITH OR ARISING OUT OF THE FURNISHING, PERFORMANCE OR USE OF THE PORTAL SOFTWARE
OR SERVICES PERFORMED HEREUNDER OR ANY DELAY IN DELIVERY OR FURNISHING THE
PORTAL SOFTWARE OR SAID SERVICES WHETHER ALLEGED AS A BREACH OF CONTRACT OR
TORTIOUS CONDUCT, INCLUDING NEGLIGENCE, EVEN IF PORTAL HAD BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGE.

9.4 PORTAL'S MAXIMUM AGGREGATE LIABILITY (WHETHER IN CONTRACT, TORT OR ANY OTHER
FORM OF LIABILITY) FOR DAMAGES OR LOSS, HOWSOEVER ARISING OR CAUSED, WHETHER OR
NOT ARISING FROM PORTAL'S NEGLIGENCE, SHALL IN NO EVENT BE GREATER THAN (a) IN
THE EVENT SUCH DAMAGE IS NOT RELATED TO SUPPORT, THE LICENSE FEE SPECIFIED IN
SCHEDULE A RELATED TO THE PARTICULAR PORTAL SOFTWARE PROGRAM WHICH CAUSED THE
DAMAGE OR LOSS, OR (b) IN THE EVENT SUCH DAMAGE OR LOSS IS RELATED TO SUPPORT,
THE SUPPORT FEES PAID BY LICENSEE FOR THE THEN CURRENT SUPPORT TERM.

9.5 No employee, agent, representative or affiliate of Portal has authority to
bind Portal to any oral representations or warranty concerning the Portal
Software. Any written representation or warranty not expressly contained in this
Agreement is unenforceable.

10 EMBEDDED REPORTING /COMPLIANCE ROUTINE; AUDIT RIGHTS

Licensee shall keep and maintain full, accurate and detailed records regarding
the License and the number of End Users of the Portal Software. Portal or its

11 ASSIGNMENT/BINDING AGREEMENT

Neither this Agreement nor any rights under this Agreement may be assigned or
otherwise transferred by Licensee, in whole or in part, whether voluntary or by
operation of law, except by way of sale of assets, merger or consolidation,
without the prior written consent of Portal, which consent shall not be
unreasonably withheld or delayed, provided that in the case of any such sale of
assets, merger or consolidation, the number of Subscribers shall not be
increased beyond the maximum number of Subscribers in the block of Subscribers
then applicable immediately prior to such sale of assets, merger or
consolidation. Subject to the foregoing, this Agreement will be binding upon and
will inure to the benefit of the parties and their respective successors and
assigns. Notwithstanding the foregoing, no transfer or assignment of Licensee's
rights hereunder shall be effective unless and until (1) Licensee has paid and
remains current on all amounts due hereunder, and (2) the purported assignee
agrees in writing to be bound by all of the obligations of Licensee hereunder.
Further, neither this Agreement nor the licenses granted hereunder shall be
transferable to any direct competitor of Portal.

valuable trade secrets and each party agrees that it shall use the Confidential
Information of the other party solely in accordance with the provisions of this

practical under the circumstances, Receiving Party provides to Disclosing Party
prior notice of the intended disclosure and an opportunity to respond or object
to the disclosure or if prior notice is not permitted or practical under the
circumstances, prompt notice of such disclosure.

12.2 In the event of actual or threatened breach of the provisions of Section 3
or Section 12.1, the non-breaching party will be entitled to immediate
injunctive and other equitable relief, without bond and without the necessity of
showing actual damage.

SUPPORT OVERVIEW

As Portal grows we are committed to continuing to develop our world-class
technical support service organization to provide the best support services to
our customer. The following are procedures that we would like to implement to
ensure that you, as a customer, receive the proper and prompt assistance when
needed.

There are currently two methods of addressing issues raised for support. They
are:

PORTAL ERROR TRACKING SYSTEM (PETS)

Production related errors are defects/bugs of Infranet that occurred during the
execution of a production system and should be reported as such in Portal's
Error Tracking System (PETS).

Please submit an error report for the problem using PETS -- www.pin.com (there
are separate instructions for how to logon to PETS and use it). Our response
time for the defect will be based on the severity levels and individual
customer's support contract. If the defect is not resolved in a satisfactory
manner, please escalate the situation per the escalation process.

WEB-BASED SUPPORT

For all those technical, development, non-production related questions, please
start by submitting the question/issue via our Web-Based Support:

      www.portal.com/WebSupport/login.htm

Each customer contact is provided with a login ID and unique password.  To
obtain your login and password, register by completing our online registration
form:

PORTAL ERROR TRACKING SYSTEM (PETS)

PETS Ticket Severity Definitions:

SEVERITY 1- PRODUCTION ISSUE - Major product defect causing complete loss of
service.  Resolution: work until complete

(Portal found bugs - major product defect that would likely cause full loss of
service to a customer's production system)

      Examples:

     -    System failure prevents end-users from accessing network service.

     -    Failover not successful in routing around problems.

     -    Repeated data loss or data corruption occurs to object data.

     -    Repeated software failures that result in total interruption of
          service.

SEVERITY 2 - PRODUCTION ISSUE/EMERGENCY DEVELOPMENT ISSUE - Serious product
defect causing major but intermittent loss of production service or preventing
imminent deployment of system under development. No workaround is available, but
operation can continue in a restricted fashion. Resolution: Work until complete.

(Portal found bugs - serious product defect that would likely cause major but
intermittent loss of service at a customer site.)

      Examples:

     -    System failure prevents end-users from signing up for service, but
          allows end users to access network services.

     -    System failure prevents billing collections from occurring, but allows
          end-users to access network service.

SEVERITY 3 -  Significant product defect causing loss of service of one or more
functions.  Workaround is not available, or functionality loss is critical to
system operation.  Resolution: Patch or next release, if imminent

      Examples:

     -    System failure prevents admin users from performing specific account
          updates, but all other functions are working. However, the missing
          function is critical to determining customer's sales commissions.

     -    System failure prevents end-users from accessing web pages for account
          information, but allows end-users to access network service. However,
          for many users, the web is the only access available to them.


                                                                        Page B 4

                                           GUIDELINES, POLICIES AND DEFINITIONS


SEVERITY 4 - Product defect causing loss of service of one or more functions.
Workaround is available, or functionality loss is not critical to system
operation. Resolution: Next or future release

      Examples:

     -    System failure prevents admin users from performing specific account
          updates, but all other system functions are working.

     -    System failure prevents end-users from accessing web pages for account
          information, but allows end-users to access network service.

SEVERITY 5 - Minor product defect causing little or no end-user visible loss of
service.  This category includes cosmetic errors or defects where the impact to
a customer's operation is minor.  Resolution:  Candidate for future release

      Examples:

     -    Documentation errors requiring correction or clarification.

     -    Most error message problems.

     -    System failure that occurs rarely and where failover successfully
          routes around the failure.

SEVERITY 10 -Enhancement request to Infranet for new feature or modification to
existing feature rendering the feature more effective, complete or easier to
use.  Resolution:  Candidate for future release

      Examples:

     -    Additional summary reports by cycle, accounts, etc.

     -    Additional screens in the web interface.


                                                                        Page B 5

Changing Severity Level of a PETS Ticket:

      When a PETS ticket is initially submitted, the submitter makes their best
      estimate of the appropriate severity level of the ticket and files it as
      such. As Portal and the submitter work on the reported issue, it may
      become clear that the severity level should be changed. If the submitter
      wishes to change the severity level, they should send an email to
      [email protected] listing the PETS id number, what severity level to
      change from and to, and why the change is being requested.

      If in reviewing the PETS ticket, Portal's analysis is that a change in
      severity levels is consistent with the definitions above, Portal will
      change the severity level and notify the submitter.

Status Definitions in PETS:

   SUBMITTED - Ticket has been logged into PETS for tracking

   PENDING - Not enough information has been logged in the ticket; more
      information is needed from the submitter for Portal to further analyze the
      problem. Information to include when submitting a PETS ticket includes:
      how to reproduce the error, any non-reproducible symptoms and any error
      messages. Customers should update the PETS ticket with the additional
      information and inform support by sending an email to
      [email protected]. Technical support will change the status of the
      ticket so that it is continued to be worked on.

   QUALIFIED - Infranet Technical Support has reviewed the ticket and qualified
      it as warranting Engineering evaluation. If the issue can be resolved
      without Engineering evaluation, the Technical Support personnel will drive
      resolution rather than qualifying it to pass to Engineering for
      evaluation.

   ASSIGNED - Engineering resources have been assigned to resolve the error.

   EVALUATED - Engineering has evaluated the ticket and considers the ticket to
      contain enough information to proceed.

   INTEGRATED - The error is fixed and tested. The fix is incorporated into a
      release of Infranet.

   DELIVERED - The fix is delivered to the customer as either a patch or a
      future release. Delivered is the final status for any PETS ticket that
      requires code changes.


                                                                        Page B 7
<PAGE>   15
                                                                PRODUCT SUPPORT
                                           GUIDELINES, POLICIES AND DEFINITIONS


   CLOSED - No action needed because the reported issue is a duplicate of an
      existing ticket, it turns out not to be an error or it cannot be
      reproduced. Closed is the final status for any PETS ticket that does not
      require code changes.

Typical Progression Through Status

      The order in which the status indicators are listed in the prior pages is
      close to the typical progression through to resolution of a PETS ticket.
      All tickets are automatically tagged with a status of Submitted when they
      are filed. Infranet Technical Support personnel are the first ones at
      Portal to review a PETS ticket. They will do one of three things. 1) They
      may see that more information is needed, note what information is needed
      in the activity log of the PETS ticket and change the status to Pending
      until more information is submitted to [email protected]. 2) They
      may determine that this PETS ticket warrants review by Portal Engineering
      and mark the status as Qualified. Or 3) they answer the question
      themselves if the answer does not require any code changes, and then mark
      the status as Closed.

      Once a PETS ticket is marked as qualified, then Portal Engineering reviews
      it, assigns it to an appropriate engineer and marks the status as
      Assigned. When an engineer reviews the PETS ticket, they may do one of
      three things: 1) Evaluate it, determine they have enough information to
      reach a resolution and mark the status as Evaluated. 2) Evaluate it,
      determine that more information is necessary, list what information is
      necessary in the activity log of the PETS ticket and mark the status as
      Pending. 3) Evaluate the ticket, determine that it should be closed for
      some reason, indicate the reason (such as duplicate of another PETS
      ticket, not reproducible or not an error) and change the status to Closed.

      After a Portal engineer has evaluated a PETS ticket and determined that
      enough information is available, the engineer will work on a fix for the
      error. Once a fix has been implemented, tested and integrated into an
      Infranet build, then the engineer will change the status to Integrated.

      After the build in which the fix has been integrated is delivered (posted
      to the Portal web site) as a Release or an Update, then the PETS ticket
      status is changed to Delivered and the activity log is updated with the
      name of the Release or Update. Delivered is the final status for any PETS
      ticket that requires code change. Closed is the final status for PETS
      tickets that do not require code changes.

Changing the Status of a PETS Ticket


                                                                        Page B 8

                                           GUIDELINES, POLICIES AND DEFINITIONS


      As the ticket progresses through to resolution, Portal will update the
      status of the PETS ticket. If the submitter wishes to update the status of
      a ticket, for example when they've provided requested additional
      information in response to a status of Pending, the submitter should send
      an email to [email protected] requesting the status change.

Activity Log in PETS Tickets

      Portal will add to the activity log of a PETS ticket as it progresses
      through to resolution. Any information that is pertinent will be added to
      the log. In particular when a ticket's status is changed to Pending,
      details of what information is needed is described in the activity log.

PETS Review Cycles

      Portal does a full review of outstanding PETS tickets at least once during
      the course of each Infranet release. Since Infranet releases are scheduled
      3 times a year, all the outstanding PETS ticket will be reviewed at least
      three times a year.

COMMUNICATION

PETS Severity 1 Tickets

      For Severity 1 tickets Portal provides updates to submitter as pertinent
      information is available. These updates are provided via phone, fax or
      email as the situation warrants. The definition of Severity 1 as complete
      loss of service in production will be strictly adhered to and any tickets
      that do not fall within this definition either initially or after a work
      around has been provided will be reassigned to a lower severity level.

PETS Severity 2 Tickets

      For Severity 2 tickets Portal provides updates to submitter as pertinent
      information is available. These updates are provided via phone, fax or
      email as the situation warrants. The definition of Severity 2 as major
      loss of service in production or preventing deployment will be strictly
      adhered to and any tickets that do not fall within this definition either
      initially or after a work around has been provided will be reassigned to a
      lower severity level.

                                           GUIDELINES, POLICIES AND DEFINITIONS


PETS Severity 3, 4, 5 and 10 Tickets

      Portal communicates updates on these tickets via PETS as pertinent
      information is available. The PETS system permits users to search for
      recently updated tickets and it will also send out an automatic email when
      a ticket is changed.

WEB-BASED SUPPORT

Technical support is available to all Portal customers with a current customer
support contract. Portal's Web-Based support provides fast and easy access to
all your technical support cases. It allows you to add a new case, or update and
monitor the status of an existing case. Each case is associated with a case
number for reference and tracking purposes.

Case Submission:

When you submit a question or issue to us, please make sure you do the following
so we can best serve you:

1. Give us a DETAILED DESCRIPTION OF YOUR PROBLEM.

2. Give us a DETAILED DESCRIPTION OF WHAT YOU HAVE DONE to try to solve the
   problem on your own. Have you read the documentation? Have your looked in the
   error log?

3. Email any configuration or log files to [email protected]. Please include
   your case number and company name in the subject header of the email. For
   example, "Portal case# 1234: dm_oracle pinlog files"

   NOTE: Be aware that when you CC people in your email to us with aliases, we
   may not get the full email address of the CC'ed person. If that is the case,
   we will be unable to send a reply to them. You will need to forward our reply
   to them yourself.

All questions submitted are researched and answered in a timely manner. Portal
will log all questions/issues in the order they are received and will work on
them IN THAT ORDER. Once the question has been understood and analyzed, an
estimate of how long it would take to resolve it will be provided back to the
customer IF an answer or a solution is not available in a reasonable amount of
time.

Technical Support Contacts

To ensure that we provide uniform support to each of our customers, each
customer account is required to designate two senior level contacts to function

SOFTWARE ERRORS

First Customer Ship Releases and Update Releases

      Portal will work on tickets of severity 1, 2, and 3 until they are
      resolved. Fixes for these tickets are targeted to be included in an Update
      Release of the currently shipping Infranet release as well as in the
      following release.

      Portal schedules one Update Release four weeks after the First Customer
      Ship (FCS) of an Infranet Release. An Update Release is a full Infranet
      release with additional fixes integrated. After the scheduled Update
      Release that Portal posts to the web 4 weeks after FCS, any other Update
      Releases are posted on an as-needed basis. For example, Portal posted
      Infranet 5.1 Update 5. Update Releases contain the cumulative set of fixes
      available for a given release. Update Releases should be downloaded and
      installed in full to ensure that you have the most recent, supported
      version of Infranet.


                                                                       Page B 12

                                           GUIDELINES, POLICIES AND DEFINITIONS


      Tickets of severity 4 are targeted for fixing in the next release,
      severity 5 for fixing in a future release and tickets of severity 10 are
      candidates for a future release.

Product Support Period

      Infranet releases are supported for a period of 6 months after the
      subsequent release of Infranet ships. For example, Infranet 5.1 will be
      supported for 6 months after the release of Infranet 5.2 or for a total of
      10 months after shipping 5.1 (since 5.2 ships 4 months after 5.1, 5.1 is
      supported for that 4 months plus an additional 6 months for a total of 10
      months.). Portal highly encourages customers to upgrade to the latest
      release of Infranet in order to benefit from the latest features and
      fixes. Yet, we understand that it does take time to migrate to the latest
      release, so we have allocated a period of a total of ten months to support
      a release: four months until the next release ships (Infranet releases
      ship three times a year, every four months) plus six months after the next
      release ships.

                            DIRECTIONS TO USING PETS2

GETTING STARTED

You can get to PETS2, login via the www.pin.com web site. Log into this site
using your current user name and password. Once on, click on PETS2. The system
will ask you for another login and password. This is not the same user
login/password that was used in PETS. Support will let you know your new login.
The password is the same as before. When you type in your login and password,
make sure you use capitals when specified. PETS2 is now case sensitive.

- --------------------------------------------------------------------------------
Select one of the schemas in the list below.

Click on Query OR  Submit (or use the buttons which follow the list) to open the
selected schema for Query OR Submit.

    PETS2                PETS:User Comments

Click on QUERY OR SUBMIT to start working with the selected schema.
- --------------------------------------------------------------------------------

You will see the above when you first login. The PETS2 schema is used for
tickets. The PETS:User Comments schema is used for User Comments.

SEARCHING AND MODIFYING A TICKET

To search or modify a ticket, choose the PETS2 schema and click on QUERY. You
may search on any one of the fields you see. You may select from the pulldown
menu for any or all of these fields. If a field is left blank, that field is
considered a wildcard. If you leave all the fields blank, all wildcards, you'll
get all your tickets in PETS2.

After you've made your search criteria selection, hit RUN QUERY and a list of
all tickets matching your set of criteria will appear. You can either view or
modify those tickets.

SUBMITTING A TICKET

To submit a ticket, choose the PETS2 schema and click on the SUBMIT button at
the top of the page to get a blank ticket. Currently, the only way to get back
to the PETS2 page is to use a bookmark or to hit "back" in your browser. We are
looking into changing that.

There are several fields that are required in submitting a ticket. They are the
following:

- - Severity         - Release     - Product      - OS        - Problem Summary
- - Problem Detail   - Last Name   - Caller ID    - Hdwr      - DB


                                                                       Page B 14
<PAGE>   22
                                                                PRODUCT SUPPORT
                                           GUIDELINES, POLICIES AND DEFINITIONS


If you don't fill in all the fields, you'll get an error message and your ticket
won't be submitted.

After you've filled everything out, click on SUBMIT at the top or bottom of the
screen. The next screen will tell you if the submission was successful. To get
back to the any of the previous screens, just hit "back" on your browser.

SUBMITTING SUGGESTIONS FOR IMPROVING OR FIXING PETS2

There are two ways to do suggest improvements for PETS2. You can either file a
ticket against PETS2 by following the instructions above and choosing PETS as a
product or you can submit a comment.

To submit a suggestion for improving or changing PETS2 itself, choose the
"PETS:User Comments" schema in the first screen after logging in and click on
SUBMIT. Fill in the Description field and the optional Comments field and click
on SUBMIT.

SEARCHING FOR A USER COMMENT

You can search for a user's comment by filling in any one of the fields. Most
likely, you will only fill in the "Company Name" field. PETS2 is case sensitive
so be sure to fill in the "Company Name" exactly as it appears when you
submitted it. Hit QUERY when you have entered in the field. PETS2 will give you
a list of comments matching your criteria. You can only view the comment even
though it says you can modify it. If you try to modify, it will give you an
error. We will change that for future releases.

THE QUERY BAR

The query bar is used for complex queries. We don't suggest you use it.

 PROJECT OVERVIEW

     The Portal Professional Services Group (PPSG) is pleased to present this
     statement of work (SOW) to Sage Networks. PPSG provides client assistance
     in the areas of implementation, training and technical support. This SOW
     describes our concept of support for the implementation of Infranet in the
     Sage Networks environment.



     Among the many benefits of Infranet is its ability to reduce Sage Networks
     time to market for new products. Therefore, PPSG's goal is to get Sage
     Networks operational within the business space as quickly as possible. To
     accomplish this, we will perform an implementation customized to meet Sage
     Networks specific requirements. In addition to the Phase 1 implementation
     effort Portal will, in parallel, assist Sage Networks in the further
     development of a roll out strategy and project plan for phases beyond the
     initial implementation.




SCOPE


     The scope of this statement of work includes the following:

         -        The performance of a mini-workshop (3 days) to further define
                  implementation requirements and the final Phase 1
                  deliverables.

         -        The development of a project workbook and detailed design
                  specification.

         -        The installation of Infranet Foundation, client applications,
                  and any purchased managers, i.e., email manager.

         -        Configuration and customization of Infranet as necessary.

         -        Unit and integration testing

         -        Cutover assistance

         -        Management reporting and meetings

                     [UUNET Technologies, Inc. Letterhead]


                 MASTER DISCOUNTED INTERNET SERVICES AGREEMENT

This Master Internet Services Agreement ("Agreement") is made by and between
UUNET Technologies, Inc., with its principal offices at 3060 Williams Drive,
Fairfax, VA 22031 ("UUNET") and Sage Networks, Inc. ("Customer") with its
principal offices located at 64 Perimeter Center, Atlanta, Georgia 30341 for the
purpose of setting forth the terms and conditions relating to the purchase of
UUNET's Internet products and services by the Eligible Participants, as defined
in Section 1 below.

1. DEFINITIONS. 

"Eligible Participants" means Customer, its Affiliates and any other entities
that UUNET and Customer mutually agree upon, are eligible to participate in the
offerings under this Agreement. "Affiliate" means with respect to a party, an
entity controlled by, controlling or under common control with such party.
"Effective Date" means the effective date of this Agreement which shall be the
last date of the signatures of a duly authorized representative of a party
affixed below.

2. SERVICES.

The services that are currently available hereunder from UUNET and its
Affiliates (the "Services") are set forth in the attached Schedule 1. UUNET may
amend Schedule 1 or Schedule 2 at any time and from time to time remove Services
if they should be discontinued or add new services (which shall be included
within the term "Services" upon such addition) by providing a revised copy
thereof to Customer. Such amendments shall be prospective only and shall not
affect any existing Service being provided by UUNET or any of its Affiliates to
Eligible Participants at the time of amendment which Services shall continue to
be offered to Customer for the balance of the Term hereof at the prices and with
the discounts set forth on Schedule 1 attached hereto.

3. PRICING AND DISCOUNTS.

3.1 The prices and discounts for Services applicable to this Agreement are
detailed in Schedule 1, and shall be applicable for the duration of the initial
term set forth in Section 6 unless otherwise amended as provided for below in
this Section 3.2. The discounts shall not be combined with promotional discounts
as may be available from time to time from UUNET. An Eligible Participant may
elect, at the time of any order for Services, the applicable discount set forth
in Schedule 1 or the terms of any promotion then in effect. In either event, the
discount or promotion shall only be available if Eligible Participant agrees to
the standard terms and conditions applicable to such Service and commits to
purchase that Service for a minimum one year term or such longer term as may be
specified in the applicable Service Agreement. 

3.2 The parties acknowledge and agree that they have negotiated competitive 
pricing for the Services.

   
3.2.1 Not more often than once every six months Customer may request that UUNET
review whether the pricing available to Customer hereunder is as competitive as
pricing for comparable services purchased from UUNET in similar quantities by
similarly situated customers, and if UUNET determines that this pricing is not
competitive then UUNET may at its election adjust the fees for the Services to
make the fees competitive or terminate this Agreement upon sixty days written
notice.
    

   
3.2.2 After two years of the Effective date of this Agreement, if industry
pricing or comparable services purchased in similar quantities from other
national Internet service providers is different than the fees set forth in
Schedule 1, at Customer's request, the parties shall renegotiate the fees for
the services to make the fees competitive with industry pricing.
    

3.2.3 For purposes of making price adjustments hereunder, UUNET may consider,
among other things, the minimum Mbps commitment, the number and type of
telecommunications lines being serviced, and the term of comparable contracts.
<PAGE>   2
4. FORECASTS.

Two weeks prior to the end of each calendar quarter Customer shall, based on the
best available information, provide UUNET a forecast of orders likely to be
generated pursuant to this Agreement on a per service and per country basis.
Customer and UUNET shall meet at Customer's principal office during the first
two weeks of each calendar quarter during the term of this Agreement to discuss
Customer's estimate of anticipated Eligible Participants' needs for Services on
a per service and per country basis for the ensuing calendar quarter.
Additionally, these meetings will be designed to promote discussions of the
most appropriate network architecture to service Sage Networks' customers. Each
of these meetings shall be followed by an executive meeting at which at least
one officer of Customer attends.

5. SERVICE ORDERS AND COORDINATION.

Eligible Participants will coordinate all orders for Services through UUNET's
designated Account Manager. Only Eligible Participants who identify themselves
as Eligible Participants under this Agreement will be offered the discount set
forth in Schedule 1. The Eligible Participant ordering Service will enter into a
service agreement with UUNET for each Service. Each service agreement shall set
forth the terms, conditions, and pricing of the Service. The current terms and
conditions applicable to purchases of dedicated Internet connections are set
forth in Schedule 2. If any Eligible Participant believes that the level of such
Service or support in any case is insufficient, that Eligible Participant may
contact UUNET's designated Account Manager for assistance with problem
resolution.

6. TERM OF THE AGREEMENT.

(a)  Unless terminated by Customer in accordance with the provisions of
     paragraph (b) of this Section 6. The initial term of this Agreement shall
     be three years from the Effective Date which term shall be automatically
     renewed for an additional one year term, provided that neither party has
     delivered to the other a written notice of intent not to renew for the
     forthcoming term not less than 60 days in advance of the end of the
     then-current term. The term commitment will commence and continue for three
     years from the Commitment date (as stated in Schedule 1) upon which
     Customer will have ordered the minimum Mbps commitment set forth in
     Schedule 1.

   
(b)  UUNET acknowledges that it is Customer's primary Internet service provider.
     UUNET agrees that that if in any calendar quarter Customer receives credits
     under the applicable Service Level Agreement referenced in Section 7 of
     Schedule 2 for more than ** of the circuits ordered from UUNET then
     Section 12 ("Primary Provider") of this Agreement shall be null and void.
    

7. CONSULTING.

UUNET will (at no additional charge) provide one day of on-site assistance once
quarterly and provide remote assistance as reasonably required to assist
Customer in routing traffic and configuring equipment.

8. LIMITATION OF LIABILITY.

NOTWITHSTANDING ANYTHING ELSE TO THE CONTRARY STATED OR IMPLIED HEREIN OR IN 
ANY SERVICE AGREEMENT, NEITHER PARTY SHALL HAVE ANY LIABILITY TO THE OTHER 
PARTY WHATSOEVER FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR 
SPECIAL DAMAGES, INCLUDING WITHOUT LIMITATION, LOSS OF PROFIT, LOSS OF REVENUE, 
OR LOSS OF BUSINESS SUFFERED BY THE OTHER OR BY ANY ELIGIBLE PARTICIPANT, 
ASSIGNEE OR OTHER TRANSFEREE OF THE OTHER, EVEN IF INFORMED IN ADVANCE OF THE 
POSSIBILITY OF SUCH DAMAGES.

9. ACCEPTABLE USE.

UUNET's services may only be used for lawful purposes. Use of any Service must
comply with the then-current version of the UUNET Acceptable Use Policy
("Policy") for the country in which the service is provided, available at the
following URL:www.uu.net/usepolicy, and in the event no Policy is available for
that country the U.S. policy shall apply. UUNET reserves the right to change
the Policy from time to time, effective upon posting of the revised Policy at
the URL. UUNET reserves the right to suspend the Service or terminate this
Agreement effective upon notice for a violation of the Policy.

10. INVOICING AND PAYMENT.

UUNET will invoice each Eligible Participant for the applicable Service in 
accordance with the terms of the applicable service agreement. The Eligible 
Participant obtaining Service will make payment for Services in accordance with 
the terms of each applicable service agreement.

11. MARKETING AND PUBLICITY.

UUNET and Customer will design and implement a joint marketing program, and
promptly after execution of this Agreement the respective points of contract of
each party shall


<PAGE>   3
agree upon a plan setting forth the approved joint activities. Such joint
marketing program shall include, but not be limited to, (i) allowing Customer to
resell UUNET Service through Customer's network of resellers, (ii) cooperating
on mutually beneficial hosting and co-location remarketing programs and (iii)
cooperation on international co-location facilities agreements. Other than (a)
identifying UUNET to Eligible Participants as Customer's preferred internet
service provider, and (b) any mutually approved joint marketing programs,
neither party shall publicize the existence of this Agreement without the
written consent of the other, except as may be required by applicable law,
regulation, or government order. Neither party may use the name, logo,
trademarks, service marks or other proprietary identifying symbols of the other
party in any advertising, signage, marketing materials, brochures or any other
materials in any medium without the other party's express advance written
consent. Any such permitted use shall be only within guidelines provided by such
party. Neither party shall issue any press release, announcement or public
statement with respect to this Agreement or the other party without the other
party's express advance written consent. Any breach of this Section shall be a
material breach of this Agreement constituting cause for termination.

12. PRIMARY PROVIDER.

   
Both parties understand that this is a "non-exclusive" agreement. However,
Customer agrees that subject to the terms of this Section, UUNET will become and
remain the primary provider of internet services for the Sage Networks. In the
event Customer obtains over 600 Mbps of bandwith for internet traffic in years
two and three of the term commitment, ** of any  bandwith over 600 Mbps shall
be purchased from UUNET. If the ** requirement is not met, Customer will pay
UUNET Shortfall Revenue in the amount of ** per Mbps for each Mbps by which
Customer has fallen short  of the ** requirement. Customer shall notify UUNET
immediately upon determining that the ** requirement in this Section has not
been met. Customer shall provide UUNET relevant records relating to this Section
at each quarterly business review held pursuant to Section 4. Notwithstanding
anything to the contrary stated herein, this Section 12 shall be inapplicable if
Customer has purchased bandwith from UUNET in an amount equal to or greater
than ** of the applicable Minimum Mbps Commitment set forth in Schedule 1.
    

13. AUDIT.

In order to verify the statements issued by Customer in connection with Section
12 or the performance of Customer's financial obligations to UUNET hereunder,
UUNET may cause, upon ten (10) days' prior notice (i) an audit to be made of the
Customer's relevant customer books and records and/or (ii) an inspection to be
made of the Customer's relevant facilities and procedures. Any audit and/or
inspection shall be conducted during regular business hours at Customer's
facilities and in a manner that does not interfere with Customer's normal
business activities. Any audit shall be conducted by an independent certified
public accountant selected by UUNET (other than on a contingent fee basis) who
will be subject to the confidentiality provisions of this Agreement. UUNET will
be entitled to receive the final written report from the selected auditor. All
records and the final written report shall remain the confidential information
of UUNET. Customer agrees to provide the selected auditor access to the relevant
records and facilities. UUNET agrees to, or to cause the auditor to, deliver a
copy of the final report to Customer promptly upon completion of the audit.
Customer shall notify UUNET within thirty (30) days of its receipt of the report
of any disagreements with the findings contained therein. Such notice shall
state the basis upon which Customer disagrees with the findings and shall be
accompanied by data to support its assertions. If within thirty (30) days of
delivery of such notice to UUNET, Customer and UUNET cannot agree on the numbers
or the amounts reported, a second audit shall be conducted by an independent
certified public accountant mutually agreed to by the parties. The cost of such
second audit shall be borne equally by both parties and the conclusions shall be
binding upon both parties. Customer shall make prompt adjustments to compensate
for any errors or omissions disclosed by the audit. Any such audit shall be paid
for by UUNET unless material discrepancies are disclosed. "Material" shall mean
an error of five percent (5%) or more of the number or amount that was reported.
If material discrepancies are disclosed, Customer agrees to reimburse UUNET for
the reasonable costs (based on current market prices) associated with the audit
in addition to all sums due. In no event shall audits be made more frequently
than annually.

14. OPPORTUNITY TO BID.

In the event Customer requires additional telecommunications services (including
Internet-protocol-based services and traditional voice services), Customer shall
provide UUNET and its affiliates an opportunity to propose terms under which
they could provide such services to Customer.

15. CONFIDENTIALITY

The prices and terms of this Agreement shall be held confidential by each party,
as shall each party's confidential or proprietary information, including,
without limitation, any information obtained by UUNET, its agents or
representatives in the course of performing an audit pursuant to Section 13 of
this Agreement ("Confidential Information"). UUNET's performance under this
Agreement, the quality of UUNET network performance, the discounts and prices
set forth in
<PAGE>   4
Schedule 1 and any data provided by UUNET to Customer regarding performance of 
the UUNET network shall be deemed UUNET Confidential Information. Neither party 
shall disclose the other party's Confidential Information to third parties 
without the other party's written consent, except as permitted pursuant to this 
Section. Each party shall disseminate the other party's Confidential 
Information among its employees only on a need-to-know basis and shall use such 
Confidential Information only for the purpose of performing its obligations 
hereunder. To the extent a party is required by applicable law, regulation, or 
a government agency or court order, subpoena, or investigative demand, to 
disclose the existence or terms of this Agreement, or the other party's 
Confidential Information, such party shall use its reasonable efforts to 
minimize such disclosure and obtain an assurance that the recipient shall 
accord confidential treatment to such Confidential Information, and shall 
notify the other party contemporaneously of such disclosure. Either party, in 
its discretion, may terminate this Agreement for cause upon ten days' notice 
and without penalty in the event of any breach of this Section. The obligations 
in this Section shall survive any termination of this Agreement for a period of 
two years.

16.  GENERAL.

This Agreement may not be assigned by either party without the prior written 
consent of the other, which consent shall not be unreasonably withheld, 
conditioned or delayed, provided, however, that this Agreement shall be 
binding upon and inure to the benefit of any successor in interest to Customer 
resulting from, among other things, a merger, consolidation, sale of stock or 
sale of substantially all of the assets of Customer. No failure on the part of 
either party to exercise, and no delay in exercising, any right or remedy 
hereunder shall operate as a waiver thereof; nor shall any single or partial 
exercise of any right or remedy hereunder preclude any other or further 
exercise thereof or the exercise of any other right or remedy granted hereby or 
by law. This Agreement supersedes all prior or contemporaneous representations, 
agreements or understandings concerning the subject matter hereof. If any term 
of this Agreement, or the application of such term to any person or 
circumstance, shall be held invalid, the remainder of this Agreement, or the 
application of such term to persons or circumstances other than those to which 
it is held invalid, shall not be affected thereby. The effective date of this 
Agreement is the last date of the signatures of a duly authorized 
representative of a party affixed below.

                                   SCHEDULE 2

                              TERMS AND CONDITIONS

1. UUNET Technologies, Inc. ("UUNET") exercises no control over, and accepts no
   responsibility for, the content of the information passing through UUNET's
   host computers, network hubs and points of presence (the "UUNET Network").
   EXCEPT AS EXPRESSLY SET FORTH IN SECTION 7 BELOW, UUNET (a) MAKES NO
   WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, FOR THE SERVICES AND
   EQUIPMENT IT IS PROVIDING, AND (b) DISCLAIMS ANY WARRANTY OF TITLE,
   MERCHANTABILITY, NON-INFRINGEMENT OR FITNESS FOR A PARTICULAR PURPOSE. Use of
   any information obtained via the UUNET Network is at Customer's own risk.
   UUNET specifically denies any responsibility for the accuracy or quality of
   information obtained through its services. UUNET shall not be liable for any
   delay or failure in performance due to Force Majeure, which shall include
   without limitation acts of God, earthquake, labor disputes, changes in law,
   regulation or government policy, riots, war, fire, epidemics, acts or
   omissions of vendors or suppliers, equipment failures, transportation
   difficulties, or other occurrences which are beyond UUNET's reasonable
   control.

2. All use of the UUNET Network and the service must comply with the
   then-current version of the UUNET Acceptable Use Policy ("Policy") which is
   made a part of this Agreement and is available at the following URL:
   www.uu.net/usepolicy.html. UUNET reserves the right to amend the Policy from
   time to time, effective upon posting of the revised Policy at the URL or
   other notice to Customer. UUNET reserves the right to suspend the service or
   terminate this Agreement effective upon notice for a violation of the Policy.
   Customer agrees to indemnify and hold harmless UUNET from any losses,
   damages, costs or expenses resulting from any third party claim or allegation
   ("Claim") arising out of or relating to use of the service, including any
   Claim which, if true, would constitute a violation of the Policy.

3. NEITHER PARTY SHALL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE
   OR CONSEQUENTIAL DAMAGES THAT RESULT FROM CUSTOMER'S OR CUSTOMER'S USERS' USE
   OF THE UUNET NETWORK AND THE SERVICE INCLUDING, WITHOUT LIMITATION, ANY SUCH
   DAMAGES FOR LOSS OF DATA RESULTING FROM DELAYS, NON-DELIVERIES, MISDELIVERIES
   OR SERVICE INTERRUPTIONS. Notwithstanding anything to the contrary stated in
   this Agreement, Customer's sole remedies for any claims relating to this
   service or the UUNET Network are set forth in Section 7 below.

4. Networks assigned from a UUNET net-block are non-portable. Network space
   allocated by UUNET must be returned to UUNET in the event Customer
   discontinues service.

5. Payment is due 30 days after date of invoice. Accounts are in default if
   payment is not received within 30 days after date of invoice. If payment is
   returned to UUNET unpaid Customer is immediately in default and subject to a
   returned check charge of $25 from UUNET. Accounts unpaid 60 days after date
   of invoice may have service interrupted or terminated. Such interruption does
   not relieve Customer of the obligation to pay the Monthly Fee. Only a written
   request to terminate Customer's service relieves Customer of the obligation
   to pay the Monthly Fee. Accounts in default are subject to an interest charge
   on the outstanding balance of the lesser of 1.5% per month or the maximum
   rate permitted by law. Customer agrees to pay UUNET its reasonable expenses,
   including attorney and collection agency fees, incurred in enforcing its
   rights under these Terms and Conditions. Prices are exclusive of any taxes
   which may be levied or assessed upon the Equipment or services provided
   hereunder. Any such taxes shall be paid by Customer. If Customer is exempt
   from otherwise applicable taxes, Customer must submit its tax identification
   number and exemption certificate at the same time it submits this Agreement.

6. Billing for UUNET service will commence when a UUNET hub and a functioning
   telephone circuit are prepared to route IP packets to Customer's site. The
   Start-up Charge is invoiced upon acceptance of this Agreement by UUNET.
   Charges for Equipment shall be invoiced upon shipment. Service is invoiced
   monthly in advance, and may be canceled only by 60 days' advance written
   notice. In the event of early cancellation of a Term Commitment, Customer
   will be required to
<PAGE>   7
    pay 75% of UUNET's standard Monthly Fee for each month remaining in the Term
    Commitment. UUNET reserves the right to change the rates by notifying
    Customer 60 days in advance of the effective date of the change.

    delay in exercising, any right or remedy hereunder shall operate as a waiver
    thereof nor shall any single or partial exercise of any right or remedy
    hereunder preclude any other or further exercise thereof or the exercise of
    any other right or remedy granted hereby or by law.

                          JOINT DEVELOPMENT AGREEMENT

      This Joint Development Agreement dated as of April 27, 1998 (this
"Agreement") is between Lotus Development Corporation, a Delaware corporation
with offices at 55 Cambridge Parkway, Cambridge, MA 02142 ("Lotus") and
Interliant, Inc., a Texas corporation with a place of business at 1301 Fannin,
Suite 700, Houston, Texas 77002 ("Interliant").

                                   Background

      Lotus has developed certain technology to be included in Louts Domino
Instant! Host ("Instant! Host") as a service provider hosting platform for
Lotus' Instant! Applications. The initial code implementing such technology is
currently included in Lotus Instant!TEAMROOM. Interliant, as a network service
provider of Lotus Notes and Lotus Domino services, is interested in developing a
set of service offerings based on Instant! Host technology that implements
Lotus' "Instant!" products and related strategies. Lotus and Interliant share a
common interest in reducing time to market for Lotus Instant! applications, and
in producing an Instant! Host platform that benefits from each party's knowledge
and expertise in producing quality Notes/Domino-based application hosting
platforms. Lotus and Interliant now wish jointly to develop commercial versions
of instant! Host on the terms and conditions set forth herein. Therefore, the
parties agree as follows:

1. Development.

      (a) Joint Responsibility. Lotus and Interliant shall have joint
architectural design, product management and product development responsibility
for Lotus instant! Host, and have agreed on resources to be contributed,
timelines, project plans and contingencies. Each party agrees in good faith to
use diligent efforts to undertake and complete the development of a version of
Lotus Instant! Host as contemplated hereunder and in accordance with functional
specifications developed and agreed to by Lotus and Interliant (the "Work").

      (b) Lotus Instant! Host Software Developer Kit, version 1.1. As agreed by
the parties, the first phase of development is the development of the Lotus
Instant! Host Developer Kit, version 1.x. This development kit will be made
available by Lotus or Interliant, as the case may be, to Lotus and Interliant
business partners at no charge. The parties acknowledge that version 1.0 of such
development kit is complete and was made available for shipment on or about July
20, 1997 and that version 1.1 is complete and was made available for shipment on
or about December 15, 1997.

      (c) Functional Specifications and the Development Schedules. During the
course of development, Interliant shall implement changes to the functional
specifications made by Lotus from time to time. Lotus shall, in consultation
with Interliant and based on reasonable work estimates supplied by Interliant,
revise any relevant development schedules as reasonably necessary in Lotus'
reasonable judgment, to accommodate changes made in the functional
specification. Nothing herein shall require Lotus to revise development
schedules based on delays attributable to Interliant or on Interliant's failure
to meet the development schedules once revised to accommodate the changes to the
functional specification.


                                       1
<PAGE>   2

      (d) Product Development Review. Lotus shall appoint an employee to serve
as project manager ("Lotus Project Manager") and Interliant shall appoint an
employee to serve as development liaison ("Interliant Liaison") throughout the
course of development contemplated by this Agreement. Initially the Lotus
Project Manager shall be Corinne Acheson and the Interliant Liaison shall be
David Botello. The parties may, at their own option, each appoint other
employees to serve in such or other formal capacities during the term of this
Agreement. The Lotus Project Manager and the Interliant Liaison shall meet at
mutually agreed times and locations in order to discuss the status and progress
of the development work on Instant! Host.

      (e) Lotus Personnel. Lotus will provide non-dedicated architectural and
product management assistance for Instant! Host, as well as qualified dedicated
development personnel to complete Instant! Host product development, pursuant to
the agreed upon development schedules.

      (f) Interliant Personnel. Interliant will provide non-dedicated
architectural and product management assistance to Lotus for Instant! Host.
Interliant will provide qualified dedicated development personnel to work with
the Instant! Host product development team, pursuant to the agreed upon
development schedules.

      (g) Documentation. The parties shall jointly write and produce any
necessary written end-user documentation and shall create the text for the
"op-screen" help and documentation for Instant! Host.

      (h) Testing. The joint Lotus/Interliant development team shall conduct
interim evaluation and testing of Instant! Host on agreed upon dates. Upon
completion of the development of Instant! Host, such joint development team
shall deliver to Lotus and Interliant a final commercial release of Instant!
Host, in both source and object code form, as well as all programmer's notes and
technical documentation used or developed in performing the Work.

      (i) Acceptance. Within ten (10) business days after the delivery by the
joint Lotus/Interliant development team to both Interliant and Lotus of each
development version and of the final release version of Instant! Host, each
party shall review and test the Instant! Host product and Lotus shall either
accept or reject the delivery. In the event of rejection, Lotus shall specify
the manner in which the version fails to meet the requirements of the agreed
upon functional specifications. After such notification, the joint development
team shall correct the aforesaid problems or deficiencies within ten (10)
business days (if practicable). Upon any redelivery, Lotus shall, in its
reasonable judgment, determine whether or not to accept such redelivered version
of Instant! Host or to require another iteration of the process.

2. Ownership; Licenses. (a) Lotus acknowledges that all code contributed or
developed by Interliant hereunder and identified as "Interliant Code" on
Schedule 1 attached hereto (the "Interliant Code") remains the sole property of
Interliant, and Interliant acknowledges that all code contributed or developed
by Lotus hereunder and identified as "Lotus Code" on Schedule 2 attached hereto
(the "Lotus Code") remains the sole property of Lotus. For the term of this

any time in a writing and by mutual agreement of the other Party. With respect
to any source code proprietary to the other party (to the extent such other

in confidence, and to protect such source code using the same degree of care it
uses to protect its own proprietary and confidential information of like
importance.

   
      (b) Subject to acceptance of Instant! Host by Lotus pursuant to Section
1(i) above, Lotus hereby grants Interliant a royalty-free license to use and
modify the Lotus Code for the sole purpose of enhancing its Domino-based hosting
services, provided that if Interliant ceases jointly developing new versions of
Instant! Host. Interliant will receive updates to the source code for new
versions developed by Lotus only so long as Interliant is actively hosting the
complete Lotus family of Domino Instant! Applications and offering them to the
marketplace.
    

      (c) Subject to acceptance of Instant! Host by Lotus pursuant to Section
1(i) above, Interliant hereby grants Lotus a perpetual, irrevocable license to
use, copy and modify, distribute, and sublicense the Interliant Code (as defined
in Section 2(a) hereof) as part of Instant! Host (or any successor product, or
product in which the Instant! Host code is incorporated), subject to the
nondisclosure requirements with respect the source code contained in said
Section 2(a). Additionally, Lotus shall have the irrevocable right to assign the
licenses granted hereunder in connection with any sale or transfer of the
Instant! Host product or the Louts Code or any exclusive licensing arrangement
with respect thereto.

   
      (d) Subject to acceptance of Instant! Host by Lotus pursuant to Section 1,
Lotus will have the right, without payment of any royalties other than those set
forth in Section 3 thereof, independently to develop and market successor
versions of Instant! Host (whether or not such versions constitute derivative
works) and extensions to Instant! Host which add additional features and
functionality, so long as such extension do not constitute derivative works.
Interliant agrees that it shall not create either extensions or derivative works
(within the meaning of the U.S. Copyright Act of 1976, as amended) of Instant!
Host or the Interliant Code which offer similar functionality as Instant! Host
as it applies to Domino applications. Except as expressly permitted in Section
2(b), Interliant may not create derivative works of the Lotus Code.
    

      (e) As long as Instant! Host contains the Interliant Code, all derivative
works of the Interliant Code created by Interliant that apply to Lotus Domino

granted to Lotus in Section 2(c) hereof herein with respect to Instant! Host.

      (f) Interliant may host other service providers using Instant! Host.
Interliant shall not otherwise have the right to resell the Instant! Host

sales of instant! Host at Lotus' published Instant! Host rates.

      (g) Interliant has the right to make pre-release versions of Instant! Host
available to its business partners in connection with their application
development efforts with the prior written approval of Lotus, pursuant to the
terms and conditions of Lotus' standard beta agreement.

      (h) If, so long as Lotus is obligated to pay royalties to Interliant
hereunder, Lotus desires, or is required, to sell or transfer all or
substantially all of the Instant! Host product or Lotus Code to an unaffiliated
third party or to IBM Global Services, Lotus shall first offer to sell such
Lotus Code to Interliant at the same price and upon the same terms (or terms as
similar as reasonably possible). Such right of first refusal shall be provided
to Interliant by written notice (the "Notice of Offer") given to Interliant of
the proposed sale or transfer. The Notice of Offer shall set forth with
reasonable specificity the price and other terms and conditions of the proposed
sale or transfer. Interliant shall then have the right, exercisable by written
notice to Lotus (the "Notice of Acceptance") delivered within fifteen (15) days
following the receipt of the Notice of Offer, to elect to purchase the Lotus
Code at the price and on the terms set forth in the Notice of Offer. Such
purchase by Interliant shall be consummated within ninety (90) days following
delivery of the Notice of Acceptance unless otherwise agreed by the parties. If
Interliant elects not to purchase the Lotus Code, then Lotus shall be free to
sell or transfer such Lotus Code to such third party.
    

      (i) Interliant agrees that, during the Term hereof, it will not sell or
transfer the Interliant Code to any unaffiliated third party, except in
connection with an acquisition by a third party of a majority of the voting
securities of Interliant or all or substantially all of Interliant's assets.

   
3. Royalties. (a) As full consideration for the satisfaction of Interliant's
development obligations in Section 1 hereof and for the licenses granted by
Interliant to Lotus in Section 2 hereof Lotus agrees to pay Interliant a
royalty equal to ** of the net revenue (determined in accordance with generally
accepted accounting principles, consistently applied) received in connection
with the licensing of Instant! Host (or any successor product) by Lotus. The
foregoing percentage may be adjusted by Lotus in good faith based on the value
of Interliant's overall contribution to the Instant! Host development effort
(including intellectual property and expertise) as reflected in the then-current
versions of Instant! Host and the Domino Instant! Host software developers kit,
provided that (i) there shall be not more than one (1) such adjustment during
the first year of the Term hereof, (ii) such adjustment may only occur ** with
respect to each new major release of Instant! Host, (iii) any such adjustment
which results in a reduction of the royalty percentage payable to Interliant
shall not reduce such royalty percentage by more than ** of the royalty
percentage that was payable with respect to the immediately preceding major
release of Instant! Host, and (iv) prior to any adjustment, Lotus informs
Interliant of its decision and engages in good faith discussions with regarding
Lotus' justification for such adjustment.
    

      (b) Lotus will establish standard rates under which it will license
Instant! Host to third parties. Lotus reserves the right to modify its standard
rates and/or licensing model as it sees fit.

      (c) Interliant will be required to pay Lotus for Instant! Host licenses at
Lotus' then applicable standard service provider rates for non-Lotus developed
Instant! applications offered for subscription to users via Instant! Host.

years, commencing on the date first above written. Thereafter, this Agreement
shall automatically renew for successive one-year renewal terms, unless either

      (e) If, so long as Lotus is obligated to pay royalties to Interliant
hereunder, Lotus incorporates all or substantially all of the Interliant Code in
Lotus Domino or in another Lotus product at no additional charge to Lotus Domino
licensees (excluding such beta, evaluation and promotional programs of limited
duration, which, in the case of evaluation and promotional programs, shall not
exceed three (3) months, as are customary in the software industry), this
Agreement shall automatically terminate, provided that in such event Lotus
agrees to pay Interliant an amount equal to ** multiplied by the royalty
percentage (expressed as a decimal) set forth in Section 3 hereof, less the
aggregate royalties paid to Interliant pursuant to Section 3 hereof through the
effective date of such termination. For purposes of this provision, a
promotional program shall not include bundling the Instant! Host product or
licenses with another product or products at no additional charge. Should Lotus
choose to bundle the Instant! Host product or licenses in such a manner, then
Lotus shall pay Interliant royalties pursuant to Section 3(a) of this Agreement
for each copy of Instant! Host or each license thereof so bundled following the
end of any permitted three-month evaluation or promotional period, based on
Lotus' then published rates or license fees. If, so long as Lotus is obligated
to pay royalties to Interliant hereunder, Lotus releases one or more additional
major versions of Instant! Host, Lotus agrees to pay an additional amount equal
to ** multiplied by the royalty percentage (expressed as a decimal) applicable
to each such additional major version less aggregate royalties paid by Lotus. In
the event that Lotus elects to discontinue Instant! Host entirely, the
provisions of the second sentence of Section 2(d) of this agreement shall no
longer apply, and Lotus will notify Interliant and will offer to either license
or assign the Lotus Code contained in Instant! Host to Interliant on terms and
conditions to be negotiated in good faith, so that Interliant may continue to
offer Instant! Host as an Interliant product following any such discontinuation.
    

      (f) Termination shall not limit or restrict any of the remedies otherwise
available to the parties hereunder.

10. Survival. In addition to the survival of the licenses as described in
Section 9(d) above, the provisions of Sections 2, 3 (but only so long as
Instant! Host contains the Interliant Code), 7, 8, 9(e), and 11 hereof shall
survive the expiration or earlier termination of this Agreement in accordance
with their respective terms.

11. Miscellaneous.

      (a) Enforceability. It is the desire and intent of the parties hereto that
the provisions of this Agreement shall be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought. Accordingly, if any particular provision to this
Agreement shall be adjudicated to be invalid or unenforceable, such provision
shall be deemed amended to delete therefrom the portion thus adjudicated to be
invalid or unenforceable and shall otherwise remain in full force and effect.

      (b) Parties Independent. In making and performing this Agreement, the
parties act and shall act at all times as independent contractors and nothing
contained in this Agreement shall be construed or implied to create an agency,
partnership or employer and employee relationship
