THE COMPANY
 
     Interliant is a provider of a comprehensive suite of hosting and enhanced
Internet services that enable its 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 mission-critical applications. 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. Since our inception in December 1997, we have grown
rapidly through the acquisition of 16 hosting and related Internet service
businesses. We provide Web hosting solutions to more than 37,000 customers,
representing more than 65,000 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, Georgia
and Houston, Texas and a recently leased facility in the Washington D.C. area.
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.
 
     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.
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
 
                                        1

sites and applications infrastructures more rapidly and cost-effectively than
internally developed solutions. We offer the following hosting solutions to our
customers:
 
Web Hosting.  We offer Web hosting solutions to meet the current and future Web
hosting needs of our customers. Our product offerings include:
 
     Virtual Hosting.  We host these Web sites on a shared server. Virtual
     hosting is an economical solution for customers with simple or moderately
     accessed sites.
 
     Dedicated Hosting.  We host these Web sites on a dedicated server, which we
     typically own and maintain. 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.  Co-located hosting allows customers with sophisticated
     mission-critical applications to own and access their servers on a 24x7
     basis while delegating the day-to-day operations and technical management
     of their site to us. We house co-located servers in separate,
     limited-access rooms in our Atlanta and Washington D.C. area data centers.
 
     In addition to these basic hosting services, we offer our customers a
selection of enhanced Internet services, including e-commerce capabilities,
multimedia hosting and community hosting.
 
Application Hosting.  We provide application hosting solutions to our customers
primarily through our Houston data center. Our application hosting solution 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 Internet rental applications which allow anyone with a Web browser and
an Internet connection to use sophisticated server-based applications.
 
     Groupware Hosting.  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
 
        - collaborative Web-based intranets and extranets.
 
     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 non-core
     competencies 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 offer 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 provide
          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;
 
        - network architecture and design;
 
        - strategic technology planning; and
 
        - application development and implementation.
 
     We seek to become the industry benchmark 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 on the equity
       of 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 certain "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 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 Interliant brand 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. ("Interliant Texas"). Interliant Texas had revenues
in 1998 of $21.2 million. In connection with that acquisition, we changed our
name from Sage Networks, Inc. to Interliant, Inc.
 
     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. These risks and uncertainties are not the
only ones facing us. Additional risks and uncertainties not now known to us or
that we currently consider immaterial may also impair our business operations.
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. This
prospectus also contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ materially from those anticipated
in the forward-looking statements as a results of certain factors, including the
risks and uncertainties described below and elsewhere in this prospectus.
 
WE HAVE A LIMITED OPERATING HISTORY
 
     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.
 
     Since inception in December 1997, we have experienced operating losses and
negative cash flows for each quarterly and annual period. As of December 31,
1998, we had an accumulated deficit of approximately $9.9 million. 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.

WE FACE RISKS RELATED TO INTEGRATION OF ACQUISITIONS
 
     Since February 1998, we have acquired 16 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.
 
     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 on a
       timely basis due to 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.
 
     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.
                                        6
<PAGE>   11
 
WE DEPEND 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.
 
WE DEPEND ON STRATEGIC RELATIONSHIPS 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.
 
     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.
 
OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE
 
     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.

WE DEPEND ON CONTINUED GROWTH OF THE HOSTING MARKET
 
     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.
 
     In addition, our success depends in large 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.
 
WE DEPEND ON THE GROWTH 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
 
     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" 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.
 
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.
 
                                        8
<PAGE>   13
 
OUR NETWORK SYSTEM COULD FAIL
 
     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;
 
     - 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.
 
WE DEPEND ON NEW HOSTING SOLUTIONS AND ENHANCED INTERNET SERVICES
 
     We have recently introduced new hosting solutions and enhanced Internet
services, including e-commerce, multimedia hosting, community hosting, rental
applications 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.
 
WE DEPEND ON OUR RESELLER SALES CHANNEL
 
     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
 
                                        9
<PAGE>   14
 
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.
 
OUR GROWTH AND EXPANSION HAS AND MAY CONTINUE TO STRAIN OUR RESOURCES
 
     We are currently experiencing rapid growth, primarily due to our
acquisition of 16 businesses since February 1998. In addition, from inception we
have grown to 489 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.
 
OUR FUTURE SUCCESS DEPENDS ON OUR ABILITY TO SUSTAIN GROWTH
 
     Our ability to sustain growth depends on our ability to:
 
     - expand or retain our business with current customers;
 
     - acquire new customers;
 
     - develop and offer new, successful products and services or differentiate
       such products and services from those offered by our competitors;
 
     - continue to identify and finance appropriate acquisitions on favorable
       terms, or at all;
 
     - retain key employees or hire, train and manage new employees; and
 
     - effectively integrate acquired, and develop existing, billing, accounts
       receivable, customer service and financial systems and develop our
       information technology systems.
 
     Our failure to sustain growth could adversely affect our business.
 
WE DEPEND ON OUR ABILITY TO GROW THE INTERLIANT BRAND
 
     Upon acquiring Interliant Texas and its application hosting business, we
began the process of offering the full range of our hosting products and
services under the Interliant brand. Prior to this, we marketed all of our
products and services under the Sage Networks brand and the brand names of
acquired companies. In order to build the Interliant brand in the Web hosting
and consulting market as well as strengthen it in the application hosting
market, we must succeed in our marketing efforts and provide high quality
services at competitive prices. We will need to increase our marketing budget
substantially as part of our brand building efforts. Our business could be
adversely affected if the Interliant brand is not well received by our Web
hosting customers, our marketing efforts are not productive or we are otherwise
unsuccessful in increasing our brand awareness.

OUR MARKET IS EXTREMELY COMPETITIVE
 
     Our market is highly competitive. 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 new and additional value-added 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
 
     - multimedia 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 we do.
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.
 
     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. We 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 adversely affect our
business.
 
                                       11
<PAGE>   16
 
     In an effort to gain market share, certain of our competitors have offered
hosting services similar to ours at lower prices than ours 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 ours. We may not be able to reduce the pricing of
our services or offer incentives in response to the actions of our competitors
without an adverse impact on our business.
 
WE DEPEND ON 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;
 
     - James M. Lidestri, our Executive Vice President;
 
     - Rajat Bhargava, our Senior Vice President, Chief Operating Officer Web
       Hosting; 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.
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 NEED TO RECRUIT ADDITIONAL SKILLED PERSONNEL
 
     We believe that our short- and long-term success depends largely on our
ability to attract and retain highly skilled technical, managerial and marketing
personnel, particularly additional management personnel in the areas of
application integration and technical support. Competition for such personnel is
intense. We may not be able to hire the necessary personnel to implement our
business strategy, or we may need to provide higher compensation to employees
than we currently expect. We cannot be sure that we will succeed in attracting
and retaining the personnel we need to continue to grow. Our inability to
attract and retain such personnel could limit our growth and have an adverse
effect on our business.
 
THERE IS UNCERTAINTY AS TO OUR ABILITY TO OBTAIN FUTURE FINANCING TO MEET OUR
NEEDS
 
     We currently anticipate that our available cash resources combined with the
net proceeds from this offering will be sufficient to meet our operating needs
and to continue our acquisition program through the end of 1999. 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
 
                                       12
<PAGE>   17
 
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.
 
WE DEPEND ON OUR ABILITY TO ADAPT TO TECHNOLOGICAL CHANGES
 
     Our market is characterized by rapidly changing technology, evolving
industry standards and frequent new product announcements. These characteristics
are exacerbated by the recent growth of the Internet, the continued growth in
the use of commercial software applications and the intense competition in our
industry. To be successful, we must adapt to our rapidly changing market by
continually improving the performance, features and reliability of our services.
We could also incur substantial costs if we need to modify our services or
infrastructure in order to adapt to these changes. Our business could be
adversely affected if we incurred significant costs or could not adapt to these
changes.
 
WE FACE RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION AND OPERATIONS
 
     Approximately 13% of our dollar amount of billings were to customers
located outside of the United States, primarily in Europe and Asia. 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 there are certain risks to conducting business internationally
such as:
 
     - different regulatory requirements;
 
     - trade barriers;
 
     - different technology standards;
 
     - different tax structures which may adversely impact earnings;
 
     - different privacy, censorship and service provider liability standards
       and regulations;
 
     - different intellectual property laws; and
 
     - political and economic instability of certain foreign countries.
 
Any of these risks could adversely affect our business.
 
WE FACE RISKS ASSOCIATED WITH THE SECURITY OF OUR SYSTEMS
 
     A significant barrier to the growth of e-commerce and communications over
the Internet has been the need for secure transmission of confidential
information. Web usage could decline if any well-publicized compromise of
security occurred. 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.
 
WE COULD FACE GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES
 
     There are currently few laws or regulations that specifically regulate
communications, commerce or hosting activities on the Internet. However, laws
and regulations may be adopted in the future that address issues such as user
privacy, pricing, and the characteristics and quality of products and services.
For example, although parts of it were ultimately held unconstitutional, the
Communications Decency Act of 1996 prohibited the transmission over the Internet
of certain types of information and content. Other nations, including Germany,
have taken actions to restrict the free flow of material deemed to be
objectionable on the Internet. In addition, several telecommunications carriers
are seeking to have telecommunications over the
 
                                       13
<PAGE>   18
 
Internet regulated by the Federal Communications Commission in the same manner
as other telecommunications services.
 
     The growing use of the Internet has burdened the existing
telecommunications infrastructure in many areas and local telephone carriers,
such as Pacific Bell, have petitioned the Federal Communications Commission to
regulate Internet service providers and online services providers in a manner
similar to long distance telephone carriers and to impose access fees on these
companies. Moreover, it may take years to determine the extent to which existing
laws relating to issues such as intellectual property ownership, libel and
personal privacy, are applicable to the Internet. Any new laws or regulations
relating to the Internet could adversely affect 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 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
 
     The law relating to the liability of online services companies and Internet
access providers for information carried on or disseminated through their
networks by their customers or other third parties is unclear. It is possible
that claims could be made against online services companies and Internet service
providers under both U.S. and foreign law for defamation, negligence, copyright
or trademark infringement, or other theories based on the nature and content of
the materials disseminated through their networks. In addition, legislation has
been proposed that imposes liability for or prohibits the transmission over the
Internet of certain types of information, and we expect additional similar
proposals in the future.
 
     If potential liability is imposed on us or other Internet service providers
for information carried on or disseminated through our or their systems, we may
be required to implement measures to reduce our exposure to such liability. Such
measures may require the expenditure of substantial resources, or may cause us
to discontinue certain 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
 
     Trademarks and other proprietary rights are important to our success and
our competitive position. We do not have any patented technology that would
prevent competitors from entering our market. Although we seek to protect our
trademarks, copyrights and other proprietary rights, these actions may be
inadequate to protect them or to prevent others from claiming violations of
their trademarks, copyrights and other proprietary rights.
 
     To date, we have not been notified that our 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 Web sites infringes on a
third party's trademark. In response, we inform the customer of this claim and,
if necessary, will terminate a customer's service. We expect that participants
in the hosting and enhanced Internet services 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 a material adverse effect upon our
business.
 
                                       14
<PAGE>   19
 
     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 BUSINESS MAY BE IMPACTED BY THE YEAR 2000 ISSUE
 
     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. 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 HAS NO PRIOR TRADING MARKET AND 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. The initial public
offering price for the shares will be determined by negotiations between us and
the representatives of the underwriters and may not be indicative of prices that
will prevail in the trading market. The stock market has experienced significant
price and volume fluctuations, and the market prices of securities of technology
companies, particularly Internet-related companies, have been highly volatile.
Investors may not be able to resell their shares at or above the initial public
offering price. 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.
 
OUR COMMON STOCK IS CONTROLLED BY A SIGNIFICANT STOCKHOLDER WHOSE INTERESTS MAY
BE IN CONFLICT WITH THOSE OF INTERLIANT AND THE OTHER STOCKHOLDERS
 
     Immediately following this offering, Web Hosting Organization LLC will
beneficially own approximately   % 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
 
                                       15
<PAGE>   20
 
(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 "Certain 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 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.
 
THE SUBSTANTIAL NUMBER OF SHARES THAT WILL BE ELIGIBLE FOR SALE IN THE NEAR
FUTURE MAY ADVERSELY AFFECT THE MARKET PRICE OF OUR COMMON STOCK
 
     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           shares of common stock outstanding immediately after this
offering. The           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.
 
     The remaining           shares of common stock are subject to restrictions
under Rule 144 of the Securities Act. Holders of a majority of such 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."
 
     A substantial number of shares of common stock issued as compensation will
also become available for resale in the public market at prescribed times. In
addition, we 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.

<PAGE>   21
 
                                USE OF PROCEEDS
 
     Interliant estimates that it will receive net proceeds from the sale of
          shares in this offering (assuming an initial public offering price of
$     ) of approximately $     million ($     million if the underwriters'
over-allotment option is exercised in full), after deduction of underwriting
discounts and commissions and expenses payable by Interliant, estimated at
$     million ($     million if the underwriters' over-allotment option is
exercised in full).
 
     Interliant currently intends to use a significant portion of the net
proceeds of this offering for acquisitions. See "Business -- Strategy" and
"-- Acquisition Program." Interliant currently has no commitments or binding
agreements with respect to any acquisitions. Interliant also expects to use a
portion of the net proceeds for increased sales and marketing activities and for
capital expenditures, including the build-out of Interliant's data centers and
repayment of a 9% promissory note issued in favor of Mathew Wolf in connection
with the acquisition of Interliant Texas. This note will be paid in full upon
consummation of the 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, Interliant
intends to invest such funds in short-term investment grade interest-bearing
securities. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."
 
                                DIVIDEND POLICY
 
     Interliant has never paid or declared any cash dividends on its common
stock. Interliant currently intends to retain any future earnings for its
business and, therefore, does not anticipate paying cash dividends in the
foreseeable future. Future dividends, if any, will depend on, among other
things, Interliant's results of operations, capital requirements, restrictions
in loan agreements and on such other factors as the Board of Directors of
Interliant may, in its discretion, consider relevant.

                                 CAPITALIZATION
 
     The following table sets forth at December 31, 1998 (i) the actual
capitalization of Interliant, (ii) capitalization on a pro forma basis to
reflect (a) the amendment of Interliant's Restated Certificate of Incorporation
to provide for authorized capital stock of 100,000,000 shares of common stock
and           shares of undesignated preferred stock, (b) the issuance of
2,647,658 shares of Series A Redeemable Convertible Preferred Stock on January
28, 1999 and the conversion of all such 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"),
(c) the issuance of 6,600,000 shares of Common Stock to Web Hosting Organization
LLC on February 9, 1999 (see "Description of Capital Stock -- The WEB Hosting
Organization Investment") and (d) the acquisitions consummated since December
31, 1998 (See "Business -- Acquisition Program") and (iii) the pro forma
capitalization adjusted to reflect the offering contemplated hereby (assuming an
initial public offering price of $     per share after deducting the estimated
underwriting discounts and commissions and offering expenses). This table should
be read 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
 
     The pro forma net tangible book value of Interliant as of December 31, 1998
was $13,438,409 or $0.38 per share of common stock. "Pro Forma net tangible book
value per share" is determined by dividing the number of outstanding shares of
common stock into the net tangible book value of Interliant (total tangible
assets less total liabilities), after giving effect to the pro forma events
listed in the introductory paragraph of "Capitalization." After giving effect to
receipt of net proceeds from the sale of the           shares of common stock
offered by Interliant hereby (at an assumed initial public offering price of
$     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 December 31, 1998 would have been $     million, or $  .  per
share. This represents an immediate increase in net tangible book value of
$  .  per share to existing stockholders and an immediate dilution of $  .  per
share to new investors purchasing shares at the initial public offering price.
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 Consolidated Financial Statements and Notes
thereto, the Unaudited Pro Forma Consolidated Financial (formerly Sage Networks,
Inc.) 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
(formerly Sage Networks, Inc.) that have been audited by Ernst & Young LLP,
independent auditors, whose report with respect thereto is included elsewhere in
this prospectus.
 
     The unaudited pro forma statement of operations data for the year ended
December 31, 1998 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 assumes that
acquisitions completed in 1999 occurred on December 31, 1998, and includes the
December 31, 1998 historical consolidated balance sheet of Interliant adjusted
for the pro forma effects of these acquisitions. The unaudited pro forma balance
sheet data also reflects the sale in January 1999 of 2,647,658 shares of the
Series A Redeemable Convertible Preferred Stock and the sale in February 1999 of
the remaining shares of Common Stock to Web Hosting Organization LLC. "See
Description of Capital Stock -- The WEB Hosting Organization Investment" and the
"-- SOFTBANK Investment".
 
     Results of operations for the period from inception to December 31, 1997
and for the year ended December 31, 1998 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. 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

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
 
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following description of Interliant's financial condition and results
of operations should be read in conjunction with the Consolidated Financial
Statements 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. Interliant's
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
 
     Interliant is a provider of a comprehensive suite of hosting and enhanced
Internet services that enable its 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 mission-critical applications. 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. Since our inception in December 1997, we have grown
rapidly through the acquisition of 16 hosting and related Internet service
businesses. We provide Web hosting solutions to more than 37,000 customers,
representing more than 65,000 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 Washington D.C. area. 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.
 
     During 1998 and 1999, Interliant's 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. Interliant acquired 16 operating businesses
during 1998 and 1999 for total consideration of approximately $111.0 million,
including transaction costs. All acquisitions have been accounted for using the
purchase method of accounting which has resulted in the inclusion of substantial
intangible assets on Interliant's balance sheet. Of the total consideration,
approximately $34.0 million and $77.0 million was or will be allocated to
tangible assets and intangible assets, respectively. During 1998, approximately
$1.4 million of amortization of the intangible assets was charged to operations.
Additionally, during 1998 stock valued at approximately $2.6 million was issued
as compensation in connection with agreements entered into with sellers of
acquired operating businesses. During 1998, approximately $0.8 million of
deferred compensation was amortized and charged to operations. 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 acquired in 1998 by Interliant have been
small and entrepreneurial in nature and highly dependent on the focus and
attention of the owners. It has been Interliant's 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, Interliant re-assigned the owner to take
advantage of unique skill sets that have broad application within Interliant. 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 Interliant and the businesses it acquired.
 
                                       22

     Since its inception in December 1997, Interliant has experienced operating
losses and negative cash flows from operating activities for each quarterly and
annual period. As of December 31, 1998, Interliant had an accumulated deficit of
approximately $9.9 million. Had the companies acquired to date been included
since January 1, 1998, the accumulated deficit would have been $28.0 million.
The revenue and income potential of Interliant's business is unproven and its
limited operating history makes an evaluation of Interliant and its prospects
difficult. Interliant anticipates increased operating expenses as it expands its
sales and marketing initiatives to continue to grow the Interliant brand, funds
greater levels of product development, continues to build out its data centers,
implements centralized billing, accounting and customer service systems and
continue our acquisition program. Although Interliant has experienced revenue
growth, primarily attributable to acquisitions, Interliant does 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, Interliant expects to incur operating losses for the
foreseeable future. There can be no assurance that Interliant will ever achieve
profitability on a quarterly or annual basis, or, if achieved, will sustain
profitability. See "Risk Factors -- We have a limited operating history."
 
RESULTS OF OPERATIONS
 
  Revenues
 
     Interliant has historically derived its revenues from Web hosting, enhanced
Internet services and consulting services. In March 1999, Interliant acquired
Interliant Texas to enter the application hosting market. Revenues for
Interliant's Web hosting business consist primarily of hosting fees and setup
fees, which cover costs incurred by Interliant to establish a customer's Web
site. Interliant provides virtual, dedicated and co-located hosting. Interliant
charges its Web hosting customers a fixed amount for bandwidth availability and
incremental fees if those fixed amounts are exceeded. In addition, Interliant's
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 Interliant's co-located customers are charged for the amount of physical
space such co-located customers' servers occupy. Interliant charges flat rates
for its enhanced Internet services. For application hosting, Interliant's
revenues are comprised primarily of a one-time implementation fee and monthly
usage fees per number of end users. For its consulting services, Interliant
charges either a fixed fee or a fee based on time and materials.
 
     Interliant's contracts with its Web hosting customers typically range in
length from month-to-month to one year, a large proportion of which are
cancellable by either Interliant or its customers with 30 days notice.
Interliant's contracts with its 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. 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.
 
     Interliant's revenues increased to $4.9 million for the year ended December
31, 1998. This increase in revenues was primarily attributable to the 12
acquisitions consummated during 1998. For acquired Web hosting providers
included for a full quarter or more, Interliant estimates that the average
quarter-over-quarter revenue growth rate among these companies for quarters
subsequent to their acquisition was less than 5%.
 
     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 $16.8 million for
the year ended December 31, 1997. This increase was primarily due to an increase
in the number of higher revenue generating customers.
 
  Cost of Revenues
 
     Cost of revenues consists primarily of salaries and related expenses
associated with network operations personnel as well as data communications
expenses, including one-time fees for circuit installation and
 
                                       23
<PAGE>   28
 
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.
 
     Cost of revenues increased to $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 $21.2 million. Interliant
Texas accounted for 56% 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 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.
 
     Sales and marketing expense increased to $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 Interliant's
strategy is to significantly increase its sales and marketing activities for
application hosting and launch a line of Web hosting products under the
Interliant brand starting in May 1999. See "Business -- Strategy" and
"-- Marketing." This will include the expansion of its sales force, development
of reseller and referral partner channels and increased marketing efforts to
grow the Interliant brand. 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 72% 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.
 
  General and Administrative
 
     General and administrative expense includes the cost of customer service
functions including finance, accounting, human resources, legal and executive
salaries as well as fees paid for professional services and corporate overhead.
 
     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
$19.6 million. Interliant Texas accounted for 21% 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.
                                       24
<PAGE>   29
 
  Depreciation
 
     Depreciation expense increased to approximately $0.7 million for 1998. This
increase was due to the acquisition of approximately $5.7 million of furniture,
fixtures and equipment, including approximately $1.4 million acquired with
operating businesses acquired by Interliant during 1998. Investments included
the build-out and acquisition of equipment for Interliant's Web hosting
facilities to ensure high levels of service to its 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. Interliant expects depreciation expense to increase in the
future as it continues 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% 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 to 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 $13.2 million. Interliant Texas accounted for $7.4 million of such
amortization expense. Interliant expects amortization expense to increase in the
future as it continues to acquire businesses.
 
  Start-up and Acquisition Integration Costs
 
     Start-up and acquisition integration costs consist primarily of salaries
for our acquisition and integration team as well as related travel expenses.
Start-up and acquisition integration costs increased to $1.7 million for the
year ended December 31, 1998. This increase was primarily attributable to the 12
acquisitions consummated during 1998. Interliant expects start-up and
acquisition integration costs to remain relatively constant in future periods.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Interliant has historically financed its operations and acquisitions
primarily from private placements of equity. As of December 31, 1998, Interliant
had approximately $6.8 million of cash and cash equivalents on a historical
basis and $12.0 million on a pro forma basis. Subsequent to December 31, 1998,
Interliant received private equity investments of $13.0 million in January 1999
and $11.0 million in February 1999 from two investor groups. See "Description of
Capital Stock -- The WEB Hosting Organization Investment" and "-- The SOFTBANK
Investment." In February 1999, Interliant acquired substantially all of the
assets of Telephonetics International, Inc., Digiweb, Inc. and all of the
outstanding capital stock of Net Daemons Associates, Inc. for approximately
$11.5 million in cash and 1,015,000 shares of common stock in the aggregate. On
March 10, 1999, 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 and 4,091,642 shares of common stock. Such assumed
liabilities included 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), Interliant's principal
commitments consist of non-cancelable operating leases and contingent payments
of earnouts to certain sellers of operating companies acquired by Interliant. If
all earnout targets are achieved in full, total
 
                                       25
<PAGE>   30
 
payments pursuant to all earnouts will be $2.5 million in cash and 37,481 shares
of common stock in 1999 and $0.5 million in cash and 37,481 shares of common
stock in 2000.
 
     During 1998, Interliant constructed a data center in Atlanta into which the
majority of the operating businesses it acquired have been or are being
integrated. Interliant believes 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.
Interliant intends to invest approximately $5.0 million to build out its 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. Interliant may
decide to construct one or more additional facilities in 1999, dependent upon
acquisition activity. Interliant's 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.
 
     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 $642,371.30 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.
 
     Management believes that its existing cash and cash equivalents are
adequate to meet operating needs through the end of 1999 and will provide enough
funds to continue its acquisition program through 1999. Thereafter, Interliant
expects to require additional financing. If Interliant's plans or assumptions
change or prove to be inaccurate, Interliant may be required to seek additional
sources of capital or seek additional capital sooner than currently anticipated.
Interliant may also seek to raise additional capital to take advantage of
favorable conditions in the capital markets. Interliant has 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
Interliant's, 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.  Interliant 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. Interliant'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
Interliant's solutions to its customers, (iii) contacting vendors of material
non-IT systems, (iv) assessment of repair or replacement requirements, (v)
repair or replacement, (vi) implementation and (vii) creation of contingency
plans in the event of Year 2000 failures. Interliant has been informed by its
vendors of material hardware and software components of its IT systems that
their products used by Interliant are currently Year 2000 compliant. Interliant
is currently assessing the materiality of its 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,
Interliant will not be able to completely evaluate whether its IT systems or
non-IT systems will need to be revised or replaced. Interliant plans to complete
its Year 2000 evaluation during the second half of 1999.
 
     Costs.  To date, Interliant has not incurred any material expenditures in
connection with identifying or evaluating Year 2000 compliance issues. Most of
its expenses have related to the 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, Interliant does not possess
the information necessary to estimate the
                                       26
<PAGE>   31
 
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 Interliant does not
anticipate that such expenses will be material, such expenses, if higher than
anticipated, could have an adverse effect on Interliant's business.
 
     Risks.  Interliant 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 Interliant's business, results of operations and financial condition.
There is no assurance that Interliant 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 Interliant'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 Interliant 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 an
adverse effect on Interliant's business. 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's control will be Year 2000 compliant. The failure by such entities
to be Year 2000 compliant could result in a systemic failure beyond the control
of Interliant, such as a prolonged Internet, telecommunications or electrical
failure, which could also prevent Interliant 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 an adverse
effect on Interliant's business.
 
     Contingency Plan.  As discussed above, Interliant 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.

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 ("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
 
     - 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.
 
                                       28
<PAGE>   33
 
     According to an industry source, more than 108 million employees worldwide
will regularly work outside of the traditional office setting by 2002. As a
result of the development of alternative workplaces, an increasing number of
businesses are relying on the Internet to enable fast and efficient
communication, not just with employees, but with all of their constituencies.
 
     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 competencies;
 
     - 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 fault-tolerant and scalable network infrastructure. 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. As a result, Interliant
believes enterprises of all sizes are seeking outsourcing arrangements to help
build effective Web sites, improve the sites' reliability and performance,
provide continuous monitoring of their Internet operations and reduce costs.
 
     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.
 
THE INTERLIANT 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
       hosting; and
 
     - consulting and Web design firms for which hosting is not their core
       competency.
 
                                       29
<PAGE>   34
 
     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. These services 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 product or
service with only limited knowledge of the bundle of products and services
required to provide the complete business solution. Interliant believes 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.
 
THE INTERLIANT SOLUTION
 
     Interliant is a provider of hosting solutions that enable its 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.
Interliant offers 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. Interliant believes it has
developed the infrastructure, resources, application management expertise and
industry relationships required to capitalize on this emerging market
opportunity.
 
     Interliant provides the following advantages to its customers:
 
     Comprehensive Hosting Solutions.  Interliant is able to provide Web hosting
services that meet its customers' needs as their Web sites evolve from low-end
marketing "brochures" to more complex, interactive Web sites and finally to
mission-critical applications. In addition, our application hosting services
such as groupware hosting and application outsourcing can provide our customers
with continuously available remote access to mission-critical applications and
data. Finally, Interliant offers consulting services and a broad range of
enhanced Internet services such as e-commerce capabilities, multimedia hosting
and community hosting.
 
                                       30
<PAGE>   35
 
     Performance and Reliability.  Interliant's hosting solutions help to ensure
that its customers' Web sites and networking applications are continuously
online and deliver data rapidly to users. Interliant's 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 ("NOCs") monitor Interliant's network on a 24x7 basis and
allow its staff to minimize service interruptions.
 
     Cost Savings.  Interliant's customers benefit from its focus on hosting and
the capital and labor investments that Interliant has made to support hosting
and enhanced Internet services. For customers to replicate Interliant's
performance and reliability would require them to make significant expenditures
for equipment, personnel and dedicated bandwidth. Interliant believes that its
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.  Interliant is dedicated to providing the highest quality
customer service. Interliant endeavors 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 (e.g., disk storage capacity and bandwidth utilization).
 
STRATEGY
 
     Interliant's 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, Interliant's strategy includes the following key
elements:
 
     Build the Interliant Brand.  Interliant believes it has established a
strong brand identity within the application hosting industry. 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 the
Interliant brand. Interliant intends to continue to build on the equity of the
Interliant brand and strengthen brand recognition by marketing its 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.  Interliant intends to continue its
acquisition program to capitalize on consolidation opportunities in the hosting
and enhanced Internet services market in the United States and overseas.
Interliant expects that these acquisitions will also result in substantial
operating synergies, greater internal growth and cost savings. Further,
Interliant plans to capitalize on certain "best practices" it may identify
within acquired companies to maintain its competitive advantage and to ensure
ongoing delivery of high quality hosting services to its customers.
 
     Expand Multiple Sales Channels.  Interliant reaches its 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. Interliant intends to continue expanding these channels to
further enhance its ability to attract customers of all sizes. As an example,
Interliant recently launched its business partner program, creating standard
incentives across the entire Interliant product line to foster growth of its
business partner network.
 
     Leverage the Interliant Customer Base.  Interliant intends to capitalize on
the enhanced revenue potential of the customer bases of its acquired companies,
leveraging the numerous cross-selling opportunities of its expanded line of
branded service offerings. Interliant will use its multiple sales channels,
including its
 
                                       31
<PAGE>   36
 
direct sales force, to target specific customer segments within its diverse
customer base with relevant new Interliant offerings to realize increased
revenues. For example, Interliant believes that it can grow its revenues by
cross-selling existing Web hosting customers with application hosting and
consulting services. Further, Interliant believes that by coordinating the sales
efforts of its combined Web hosting, application hosting and consulting sales
forces, it can increase customer leads and referrals. Finally, Interliant
intends to assimilate the customer bases of its acquired companies into a
unified customer information management system to facilitate sophisticated
analysis and segmentation of its total customer base and thus enable it to
maximize marketing and sales opportunities.
 
     Develop Strategic Relationships.  Interliant has established and continues
to seek strategic relationships that enhance its infrastructure and distribution
capabilities and broaden its product offerings. Interliant believes that its
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 it to
provide complete, scalable and reliable hosting solutions to its customers,
resellers and referral partners.

</TABLE>
 
- ---------------
 * Prices are representative for products marketed under the Interliant brand
   and may not be representative for our products marketed under other brand
   names.
 
     All product offerings hosted in the Atlanta and Houston data centers are
designed to achieve optimal performance through features such as:
 
     - sophisticated monitoring, notification and diagnosis;
 
     - 24x7 customer support through the NOCs and customer service centers;
 
     - remote access management and reporting tools;
 
     - redundant and high-speed network;
 
                                       32
<PAGE>   37
 
     - 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 the Interliant
brand 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.
 
     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 Interliant's 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 Interliant brand 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. We derive a
substantial majority of our Web hosting revenues from virtual hosting.
 
     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 Interliant. 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. Interliant supports most
leading Internet hardware and software system vendor platforms, including
Solaris (Sun Microsystems, Inc. platform), Microsoft Windows NT (Intel/PC
platform) and Linux (Cobalt Networks, Inc.).
 
     Prices for dedicated hosting products marketed under the Interliant brand
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.  Interliant currently provides co-located hosting
services in its 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 Interliant's 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 the Interliant brand
range from $500 to $40,000 a month, which incorporates fees such as bandwidth
charges and space. For certain customers of acquired businesses, the price range
may be lower. In 1998, our average co-located customer paid $750 per month.
 
                                       33
<PAGE>   38
 
     We also provide the following enhanced Internet services to our Web hosting
customers:
 
     E-commerce Capabilities.  Through its reseller relationships, Interliant
offers a variety of e-commerce solutions to help businesses create and maintain
a successful Web storefront. Representative 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
 
     - 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.  Interliant allows its customers to include various
multimedia capabilities in their Web sites, including streaming audio and video
hosting. With the acquisition of Telephonetics International, Inc., Interliant
has added audio production and hosting capabilities to the suite of Internet
services available to its customers. In addition, Interliant provides its
customers with the ability to include Real Networks and Microsoft NetShow
content within their Web sites.
 
     Community Hosting.  Interliant allows customers of all sizes to include
community-building features such as e-mail and chat hosting. We provide POP
("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
 
     Interliant offers application hosting services which consist of groupware
hosting and application outsourcing solutions that provide its customers with
24x7 remote access to mission-critical applications and data.
 
     Groupware Hosting.  Interliant offers its customers a broad spectrum of
groupware hosting solutions for Lotus Notes/Domino, the industry-leading
groupware platform. Interliant's groupware hosting services provide
infrastructure 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;
 
     - sophisticated, collaborative Web-based intranets and extranets; and
 
     - proprietary or custom applications built for the groupware platform.
 
     Interliant seeks to provide the following benefits to its customers hosting
their groupware implementations with Interliant;
 
     - 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. Interliant's customers have
 
                                       34
<PAGE>   39
 
the option of using shared or dedicated servers in an Interliant data center for
their groupware hosting services, or can have their on-premise server managed by
Interliant's customer-managed server offering. Prices for Interliant's groupware
hosting services range from $1,500 to over $100,000 a month.
 
     Interliant provides hosting for Lotus Notes/Domino on both shared and
dedicated servers at an Interliant data center 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 servers at Interliant using the Internet or a
variety of private network options, including frame relay, dedicated lines and
local dialup access in more than 160 countries. Interliant provides 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, Interliant 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
Interliant is considering further expansion of this program to enhance its
Microsoft Exchange hosting offering.
 
     As part of its groupware hosting implementation process, Interliant starts
with best-practice system configurations and works with its 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 (Redundant Array
of Inexpensive Disks) storage and full server clustering. Once installed,
Interliant not only monitors 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.  Interliant's application outsourcing offers
customers an integrated solution that combines packaged application software
with managed hosting services. Interliant believes 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, Interliant enables businesses of all sizes to capitalize on the
latest Internet-enabled technologies while outsourcing non-core competencies
such as deployment and migration strategies and maintenance or software upgrades
to a third party. Interliant's branded application hosting services address the
following major business process areas:
 
     - Legal Automation.  Interliant's 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 Interliant's data centers.
       Interliant has entered into strategic alliances with application
       providers such as Caseworks, Tripoint Systems Development Corp., Occam's
       Razor Technologies and First Use Registration, L.L.C. to deliver a
       variety of legal automation solutions to the marketplace. Interliant
       believes that these solutions provide an effective and secure extranet
       for lawyers, including those who already have other applications in
       place. The legal automation suite of applications currently
 
                                       35
<PAGE>   40
 
       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.
 
     - Sales Automation.  Interliant's 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. Interliant believes that
       selling this solution as a service, rather than a technology, reduces the
       customer's initial capital investment, thereby making it easier to
       minimize the customer's technology risk. Accordingly, it also allows
       Interliant to engage clients in long-term contracts with fixed monthly
       payments. The application solution is customized, deployed, and fully
       managed and supported by Interliant, providing a single-source solution
       to customers. Interliant partners with leading packaged commercial
       software vendors, hardware vendors and system integrators to deliver
       these solutions.
 
            Interliant's sales automation services can be accessed through
       Interliant's 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 Interliant, 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, Interliant offers comprehensive solutions for corporate,
       academic, and non-profit customers. These solutions encompass
       browser-based, asynchronous (any time, any place) and synchronous (same
       time, any place) learning technologies, sophisticated course and student
       management systems, online facilitation, application sharing and
       whiteboard functionality. In addition, Interliant's distributed learning
       solutions leverage its core competencies:  Web hosting, multimedia
       technology and e-commerce, to deliver a complete package to the
       Interliant customers.
 
            Layering distributed learning know-how and functionality on top of
       its existing infrastructure services allows Interliant to quickly deliver
       cost-effective solutions. Interliant's 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.  Interliant 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 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. Interliant establishes
       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 Interliant and
       Lotus. Interliant has established a portal site, www.appsonline.com, that
       contains a catalog for these Internet rental applications.
 
       Interliant's 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
 
     Interliant provides consulting services for Intranet, extranet and
application hosting solutions, as well as for internal networking
implementations and back-end Web development projects. In addition, Interliant
provides support for its customers' enterprise networking needs. Interliant's
consulting services are scaled to meet each client's needs. Interliant addresses
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.
 
ACQUISITION PROGRAM
 
     Since inception, Interliant has acquired 16 companies and intends to
continue its acquisition program. Specifically, Interliant seeks 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.
 
Interliant believes that the integration of acquired companies will create
economies of scale and generate significant operating efficiencies. Because of
our ongoing acquisition strategy, Interliant expects that at all times some
portion of its acquired companies will be in various stages of integration.
Interliant seeks to identify areas in which acquired companies outperform its
competitors and adopt their "best practices." Once Interliant acquires 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 an Interliant facility. Generally, the
customers of the acquired company are then migrated onto the Interliant 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. Interliant's platform is typically more
robust than that of the acquired company and standardization allows Interliant
to manage the servers more efficiently. In certain circumstances, however,
Interliant finds that it is not strategic or cost-effective to migrate customers
to the Interliant platform.
 
     Customer Service Integration.  Interliant integrates its customer service
operations for its acquired Web hosting customers at its data center in Atlanta
and for its application hosting customers in Houston. By centralizing hosting
customer service, Interliant believes that it can improve performance while
reducing costs. In Atlanta, Interliant has 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 Interliant acquires
do not have adequate back-office systems or procedures. As a result, Interliant
is in the process of transitioning acquired companies onto the PORTAL Infranet
billing system. With PORTAL Infranet, Interliant's resellers, referral partners
and
 
                                       37
<PAGE>   42
 
customers will be able to obtain monthly statements delivered electronically
which Interliant believes will provide them with easy access to and accurate
tracking of their hosting expenditures. In particular, Interliant believes 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.  Interliant expects to integrate the majority of its
acquired companies into the Interliant product line, with uniform branding,
pricing strategies and distribution channels. In certain cases, however, where
an acquired company's brand is already established, Interliant 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 Interliant. Our long-term goal, however, is to migrate most
product offerings to the Interliant brand.
 
     The following chart identifies the 16 hosting and Internet-related service
companies acquired by Interliant, or from which Interliant has acquired
significant assets.

customers' needs. The following is a list of selected companies with whom
Interliant has a strategic relationship:
 
     IBM Corporation.  Interliant is 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

Lotus' highest recognition, the Lotus Beacon Award, most recently in January
1999.
 
     Interliant and Lotus Development Corporation are parties to a Joint
Development Agreement, dated April 27, 1998, which has a term of two years and
is automatically renewed for successive one year terms unless terminated by
either party upon prior written notice. Under this agreement, Lotus and
Interliant co-develop Lotus' Domino Instant!Host platform, which enables
application developers to deploy and offer Web-based collaborative applications.
 
     Microsoft Corporation.  Interliant is a Microsoft Certified Solution
Partner (MCSP) and is currently engaged in several strategic initiatives with
Microsoft. Interliant and Microsoft have entered into a co-marketing and
promotion agreement whereby Microsoft will include Interliant's 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 Interliant and its involvement in the
promotion of FrontPage 2000. In return, Interliant offers incentives on certain
of its services to induce the public to host a FrontPage 2000 Web site and has
agreed to feature Front Page 2000 on its Web site with greater frequency and
visibility than any competing product. 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.

     Interliant is also participating in a Microsoft initiative called the
Complete Commerce program. In conjunction with selected other MSCP Partners,
Interliant 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 Interliant market this program,
including promotional activities, marketing activities and participation in the
customer engagement activities. Our marketing activities for the Complete
Commerce program are scheduled to commence in April 1999. Interliant also
intends to develop services based on Microsoft's Commercial Internet Server.
Microsoft or Interliant can terminate this relationship at any time.
 
     UUNET Technologies, Inc.  Interliant has entered into an agreement with
UUNET to be Interliant's primary connectivity provider on a worldwide basis.
UUNET has agreed to provide minimum levels of connectivity from 100 Mbps to 600
Mbps of bandwidth. UUNET has agreed to significant discounts and competitive
pricing assurances over the term of the agreement. The connectivity may range in
capacity from T-1 to DS-3 to OC-12. At our Atlanta data center, we are currently
installing four OC-3 connections to diverse hubs in UUNET's network utilizing
diverse fiber for redundancy. Interliant may be subject to certain penalties
under its agreement with UUNET if certain usage requirements are not met. The
agreement has a three-year term and will be renewed automatically for an
additional year unless either party notifies the other of its intent not to
renew. In addition to the connectivity provisions, Interliant and UUNET have
agreed to develop and implement a joint marketing program including (i) allowing
Interliant to resell UUNET services through its network of resellers, (ii)
cooperating on mutually beneficial hosting and co-located remarketing agreements
and (iii) cooperating on international co-location facilities agreement.
 
     Equant, N.V.  Interliant has entered into an agreement in which Equant,
N.V. provides worldwide local dialup (X.25 and PPP) and dedicated (frame relay)
connectivity from more than 160 countries. Equant, N.V. provides significant
discounts to Interliant and competitive pricing assurances. In addition, Equant,
N.V. has entered into a distribution agreement with Interliant, in which Equant,
N.V.'s worldwide sales force is able to offer Interliant's groupware and
application hosting services to its customers. This agreement terminates on
December 19, 1999 unless the parties agree to renew the agreement by June 19,
1999.
 
     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. Interliant
has a worldwide non-exclusive fee-bearing license to (i) reproduce exact copies
of these software products onto its servers and to allow its customers to use
these products, (ii) reproduce exact object code copies of the products and
(iii) market and distribute the products as stand-alone products or bundled with
other Interliant product offerings. Interliant has agreed to certain minimum
purchase level commitments in its agreement with Allaire. In addition to the
fees Interliant pays for these licenses, Interliant has agreed to promote and
market actively Allaire's products. Interliant and Allaire have also agreed to
participate in certain joint marketing and promotional activities. Interliant's
one-year agreement with Allaire 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.
 
     Elemental Software, Inc.  Interliant has been granted a non-exclusive
license to market and resell Drumbeat(TM) 2000. By working with a Drumbeat(TM)
2000 ISP Hosting Partner such as Interliant, organizations will be able to
publish data-driven Active Server Pages (ASP) applications without the need to
set up and administer Web servers locally. As an ISP Hosting Partner, Interliant
also provides hosting accounts for trial Drumbeat(TM) 2000 users. The agreement
provides for Interliant to become a Drumbeat(TM) 2000 reseller for which it will
receive preferred pricing on each sale of Drumbeat(TM) 2000 generated through
the Elemental Software/ Interliant e-commerce Web site. Interliant and Elemental
have agreed to undertake certain cross marketing activities to promote the
launch of their partnership, including press releases, Web advertising and a
special promotion by Interliant of Drumbeat(TM) 2000. In addition, Interliant
has been given the opportunity to provide an insert card to be included in the
Drumbeat(TM) 2000 product packaging promoting its services. This agreement may
be terminated by either Elemental or Interliant with thirty days prior notice to
the other.
 
                                       40

     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 Interliant's customers can sell their
products and services online. Under the terms of the agreement, Interliant pays
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
Interliant. In addition, Interliant and iMALL have agreed to determine in good
faith by April 23, 1999 a minimum number of merchants Interliant is to have
using iSTORE(TM) in order for the terms of this agreement to remain in effect.
Interliant's agreement with iMALL states that it is intended to establish a
long-term relationship between Interliant and iMALL and as such has a three-year
term.
 
SALES AND DISTRIBUTION
 
     Interliant sells its hosting services to its customers through a variety of
sales channels. The following schematic represents Interliant's sales approach.
The prices set forth below are for product offerings marketed under the
Interliant brand.
                                  [FLOW CHART]
 
     Interliant has 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. Interliant's acquisition strategy has facilitated the
integration of different indirect and direct distribution channel models used by
acquired companies and has enabled Interliant to customize them to fit the needs
of specific markets in which it competes.
 
     Internet Marketing.  Interliant's Internet marketing sales program offers
an automated online sales interface to its customers that enables them to
purchase hosting services on a 24x7 basis from its Web site at
www.interliant.com or purchase Internet rental application services at
www.appsonline.com.
 
                                       41
<PAGE>   46
 
     Telesales.  In the telesales area, Interliant currently acquires, and plans
to develop further, its 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, Interliant's goal is
to develop the leading reseller and referral partner program in the industry
through its recently introduced business partner program. Interliant's 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
Interliant's prospective customer base as well as a sales force capable of
selling Internet services. The benefits to Interliant 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 solutions to
meet customer needs. Interliant offers its partners a discount from Interliant's
retail price on both products and services.
 
     Interliant believes that its 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 Interliant's hosting services and applications;
 
     - advanced technical support;
 
     - sales and marketing support services; and
 
     - training and support programs.
 
     Direct Sales.  Interliant has 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, Interliant has 52 employees engaged in distribution
and sales.
 
MARKETING
 
     Interliant markets its full range of branded hosting solutions via an
integrated marketing program. Interliant 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 Interliant's position as a full
service hosting provider. In addition, Interliant 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 Interliant's Web site to generate greater numbers of qualified
leads and to further increase awareness of the Interliant brand.
 
     When an acquired company's brand is already well-established, Interliant
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 Interliant. Interliant's long-term goal, however, is to migrate most of
its acquired product offerings to the Interliant brand. Interliant products are
available from its primary Web site at www.interliant.com as well as at
www.appsonline.com.
 
     Interliant expects to increase its marketing expenditures in order to
support its brand marketing and lead-generation efforts. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
CUSTOMER SERVICE
 
     Interliant views customer service as a critical part of its business
strategy. Interliant's customer service group has 129 employees who are mainly
located in its Atlanta and Houston data centers. The customer
 
                                       42
<PAGE>   47
 
service group is responsible for providing customer service to all of
Interliant's customers as well as its resellers and referral partners, including
helping customers to initially set up their Web sites, answering technical
questions or helping customers use Interliant's application hosting solutions
and other enhanced offerings. Through Interliant's customer service systems,
customer service representatives can generally resolve any issues in a timely
manner via e-mail or Interliant's toll-free number.
 
     Web Hosting Customer Service.  Interliant's Web hosting customers are
primarily serviced through its Atlanta data center. To ensure that each Web
hosting customer is connected with the customer service representative best able
to address its needs, Interliant's 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 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, Interliant is 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 Interliant believes will
provide them with easily accessible and accurate tracking of their hosting
expenditures. In particular, Interliant believes 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.  Interliant's application hosting
customers are primarily serviced through its 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.  Interliant also provides 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, Interliant 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
 
     Interliant has developed a secure, reliable, high-performance, and scalable
hosting solution, which it believes 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 Interliant's
personnel in Atlanta and Houston.
 
                                       43
<PAGE>   48
 
Interliant's strategy in developing its hosting solution focuses on utilizing
internally created technological innovations that it integrates with leading
software and hardware providers.
 
     Web Hosting Platform.  Although industry-standard Web servers are adequate
for basic Web hosting, Interliant believes that efficiently managing large
numbers of Web sites and users on a single server requires significant
technological innovations. Accordingly, Interliant has focused its technology
development efforts on creating various operating system level tools to
facilitate a high customer to server ratio. Interliant has developed multiple
Web hosting platforms that permit efficient hosting of more than 5,000 Web sites
on a Sun Microsystems, Inc. Solaris server. Interliant has 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.
Interliant's solution is scalable, allowing servers to be added while being
monitored centrally independent of where they are located. To address the
diverse requirements of its customers, Interliant offers Web hosting services on
a range of operating systems and computing platforms including Solaris (Sun
Microsystems, Inc. platform), Microsoft Windows NT (Intel/PC platform) and Linux
(Cobalt Networks, Inc.).
 
     Application Hosting Platform.  Interliant maintains a state-of-the-art data
center in Houston from which it manages its 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 Interliant's customer base. Consequently Interliant employs 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. Interliant offers connectivity to its systems from virtually anywhere in
the world, enabling customers to deploy global solutions. Customers can access
Interliant via the Internet, or through X.28 connections provided by Compuserve
and Equant, N.V. in more than 160 countries, or over Frame Relay through AT&T
Corp., Sprint Corporation, and MCI WorldCom, Inc. or domestically via a
toll-free number. Interliant uses 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 the entire Interliant
network, as well as consistency of security measures across all of its current
hosting platforms.
 
     Network Operations.  In order to provide its customers with high-quality
service, Interliant has invested substantial resources in building its network
infrastructure. Interliant has designed its network to minimize the effect of
any interruptions. Interliant has also implemented security measures and
monitoring systems to ensure that Interliant's network is protected, identify
potential sources of failure, limit downtime and notify staff of any problems.
Although Interliant has attempted to build redundancy into its network and
hosting facilities, its data centers are currently subject to various single
points of failure, and a problem with one of its routers or switches could cause
an interruption in the services Interliant provides to some of its customers.
 
     Interliant's NOCs are responsible for monitoring Interliant's entire
network on a 24x7 basis. Interliant monitors 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 Interliant has established procedures
for rapidly resolving any technical problems that arise. The NOCs are fully
integrated into Interliant's customer service facilities.
 
     Interliant currently has 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 Interliant's primary Web
hosting facility and the Houston data center is Interliant's primary groupware
and application outsourcing facility. The customer service and network
monitoring infrastructures are based in Atlanta and Houston.
 
     The Washington, D.C. area data center currently serves as a co-location
facility. Interliant has recently entered into a ten-year lease for
approximately 13,000 square feet of space in the Washington, D.C. area.
Interliant intends to use a portion of the proceeds from this offering to build
out this space and create a third
                                       44
<PAGE>   49
 
state-of-the-art data center for hosting and providing customer service. Once
the construction of this new space is completed, all of Interliant's Washington,
D.C. area operations will be moved into the new space. See " -- Facilities" and
"Use of Proceeds."
 
COMPETITION
 
     The market served by Interliant 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 Interliant
expects that it 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.
 
     Interliant may not have the resources, expertise or other competitive
factors to compete successfully in the future.
 
     Interliant's 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 Interliant's 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 Interliant. 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 Interliant. 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 Interliant.

     In an effort to gain market share, certain of Interliant's competitors have
offered hosting services similar to those of Interliant at lower prices than
those of Interliant or with incentives not matched by Interliant. In addition,
certain of Interliant's competitors may be able to provide customers with
additional benefits, which could reduce the overall costs of their services
relative to those of Interliant. Interliant 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.
Interliant also believes that the market in which it competes 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 Interliant's
business.
 
INTELLECTUAL PROPERTY RIGHTS
 
     Interliant relies on a combination of copyright, trademark, service mark,
trade secret laws and contractual restrictions to establish and protect certain
proprietary rights in its services. Interliant has no patented technology that
would preclude or inhibit competitors from entering Interliant's market. The
steps taken by Interliant to protect its intellectual property may not prove
sufficient to prevent misappropriation of Interliant's technology or to deter
independent third-party development of similar technologies. The laws of certain
foreign countries may not protect Interliant's services or intellectual property
rights to the same extent as do the laws of the United States. Interliant also
relies on certain technologies that it licenses from third parties. 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 an adverse effect on Interliant's business.
 
     To date, Interliant has not been notified that its services infringe on the
proprietary rights of third parties, but third parties could claim infringement
by Interliant with respect to current or future services. From time to time,
Interliant is notified that the content of one of its customer's sites infringes
on a third party's trademark. In response, Interliant informs the customer of
such claim and, if necessary, will terminate a customer's service. Interliant
expects that participants in its markets will be increasingly subject to
infringement claims as the number of services and competitors in Interliant's
industry segment grows. Any such claim, whether meritorious or not, could be
time-consuming, result in costly litigation, cause service installation delays
or require Interliant to enter into royalty or licensing agreements. Such
royalty or licensing agreements might not be available on terms acceptable to
Interliant or at all. As a result, any such claim could have an adverse effect
upon Interliant's business.
 
GOVERNMENT REGULATION
 
     Interliant is 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 Interliant and/or its customers to
potential liability, which in turn could have a material adverse effect on
Interliant's 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 Interliant
or increase the cost of doing business or in some other manner have an adverse
effect on Interliant's 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
                                       46
<PAGE>   51
 
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.
 
     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 Interliant's business.
 
     Any new legislation or regulation, or the application of laws or
regulations from jurisdictions whose laws do not currently apply to Interliant's
business, could have an adverse effect on Interliant's business.
 
EMPLOYEES
 
     As of the date hereof, Interliant has 489 employees (including 19 on a
contract basis), of which 86 are in sales, distribution and marketing, 174 are
in engineering and service development, 129 are in customer service and
technical support, 92 are in finance and administration and 8 in acquisition
integration. Interliant believes that its future success will depend in part
upon its continued ability to attract, hire and retain qualified personnel.
Although Interliant believes it has 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 Interliant may not be able to
identify, attract and retain such personnel in the future. None of Interliant's
employees are represented by a labor union, and management believes that its
employee relations are good.
 
FACILITIES
 
     Interliant's 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. Interliant also leases 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 the Washington, D.C. area under a
lease that expires in July 2001. Interliant also leases 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, Interliant has recently leased
approximately 13,000 square feet of space in the Washington, D.C. area under a
lease that expires in 2009. A portion of the proceeds of this offering will be
used by Interliant to build-out this space. Once the construction of this space
is completed, all of Interliant's Washington D.C. area operations will be moved
into this space. See "Use of Proceeds" and "Business -- Technology and Network
Operations."

OPTION GRANTS IN LAST FISCAL YEAR
 
     None of the Named Executive Officers were ever granted nor do any such
individuals own any options to purchase common stock of Interliant.
 
STOCK OPTION PLAN
 
     The Board of Directors of Interliant has adopted and the stockholders of
Interliant have approved Interliant's 1998 Stock Option Plan (the "Plan"), under
which stock options may be granted to officers, employees and consultants of
Interliant and its subsidiaries. The Plan permits the grant of stock options
that
 
                                       52
<PAGE>   57
 
qualify as incentive stock options ("ISOs") under Section 422 of the Internal
Revenue Code and nonqualified stock options ("NSOs"), which do not so qualify.
Interliant has authorized and reserved up to 3,800,000 shares of the common
stock for issuance under the Plan. Interliant has issued options for the
purchase of approximately                shares of the common stock under the
Plan. The shares may be unissued shares or treasury shares. If an option expires
or terminates for any reason without having been exercised in full, the
unpurchased shares subject to such option will again be available for grant
under the Plan. In the event of certain corporate reorganizations,
recapitalizations or other specified corporate transactions affecting Interliant
or the common stock, proportionate adjustments may be made to the number of
shares available for grant and to the number of shares and prices under
outstanding option grants made before the event.
 
     The Plan is administered by the Compensation Committee of the Board of
Directors (the "Committee"). Subject to the limitations set forth in the Plan,
the Committee has the authority to determine the persons to whom options will be
granted, the time at which 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 and the duration of the exercise period. The
Committee may provide for the acceleration of the exercise period of an option
at any time prior to its termination or upon the occurrence of specified events,
subject to limitations set forth in the Plan. Subject to the consent of an
optionee, the Committee has the authority to cancel and replace stock options
previously granted with new options for the same or a different number of shares
and having a higher or lower exercise price, and may amend the terms of any
outstanding stock option to provide for an exercise price that is higher or
lower than the current exercise price.
 
     All officers, employees and consultants of Interliant and its subsidiaries
are eligible to receive grants of stock options under the Plan, as selected by
the Committee. The exercise price of shares of common stock subject to options
granted under the 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 the
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 (determined at
the time of grant) that may be subject to ISOs that become exercisable by any
one employee in any one year is limited by the Internal Revenue Code to
$100,000. Options granted under the Plan will generally become vested and
exercisable over a four-year period in equal annual installments, unless the
Committee specifies a different vesting schedule. In the event of a "change in
control" of Interliant (as defined in the Plan), each option that was not then
vested will become fully vested and immediately exercisable.
 
     All options granted under the Plan are nontransferable by the optionee,
except for transfers upon the optionee's death 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 death or disability. In the case of any other
termination of employment, outstanding options that have previously become
vested will remain exercisable for a period of 90 days, except for a termination
"for cause" (as defined in the Plan), in which case all unexercised options will
be immediately forfeited. Under the 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.
 
     The Plan has a term of 10 years, subject to earlier termination or
amendment by the Board of Directors, 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. The 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 Interliant's Compensation
Committee during fiscal year 1998. During 1998, no committee member was an
officer or employee of Interliant. In addition, no interlocking relationship
exists between the Board of Directors of Interliant or Interliant's Compensation
 
                                       53
<PAGE>   58
 
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
 
     Interliant has entered into employment agreements (the "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 (with
automatic one-year renewals, subject to earlier termination as provided in the
Agreements). Under the Agreements, the employees are also entitled to
participate in the employee benefit plans of Interliant which are generally
available to the senior officers of Interliant.
 
     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 Interliant 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 Interliant 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.
 
     The Agreements include certain restrictive covenants for the benefit of
Interliant relating to non-disclosure by the employee of Interliant's
confidential business information, non-solicitation of Interliant's customers
and noncompetition by the employee with Interliant's business for a period of
two years following termination of employment with Interliant.
 
     Mr. Feld, through Intensity Ventures, Inc., has entered into a one-year
consulting agreement with Interliant with identical terms to the Agreements
(including annual compensation), except (i) Mr. Feld is not entitled to
participate in Interliant's employee benefit plans and (ii) the annual
consulting fee will be paid to Intensity Ventures, Inc. on a gross basis as an
independent contractor.
 
     Interliant has also entered into a two-year employment agreement with Mr.
Lidestri (the "Lidestri Agreement") which shall automatically be extended on a
month-to-month basis from the end of the term (subject to earlier termination as
provided in the Lidestri Agreement). The Lidestri Agreement provides for an
annual base salary of $180,000 and an annual bonus of up to $70,000 which amount
is determined based upon whether Mr. Lidestri meets or exceeds specified
performance objectives. In addition, under the Lidestri Agreement, Interliant is
obligated to pay Mr. Lidestri a signing bonus of $150,000 with $100,000 of such
bonus having been paid in March 1999 and the remaining $50,000 of which is
payable on the first anniversary of the Lidestri Agreement.
 
     Under the Lidestri Agreement, Mr. Lidestri is entitled to participate in
the employee benefit plans of Interliant which are generally available to the
employees of Interliant. The Lidestri Agreement includes provisions that are
effective upon termination of Mr. Lidestri's employment under certain
circumstances. Upon termination of Mr. Lidestri's employment by Interliant
without cause or by Mr. Lidestri for certain reasons as set forth in the
Lidestri Agreement, Mr. Lidestri shall be entitled to severance equal to (i) any
remaining unpaid portion of his signing bonus plus (ii) the greater of (A) the
unpaid portion of his annual base salary and other compensation for the
remainder of the term of the Lidestri Agreement, including a pro rata portion of
the performance-based bonus for the year in which his employment is terminated
reflecting the portion of the year during which he was employed by Interliant or
(B) an amount equal to six months of his monthly base salary plus a pro rata
portion of the performance-based bonus for the year in which his employment is
terminated reflecting the portion of the year during which he was employed by
Interliant. If Interliant terminates the Lidestri Agreement for cause, Mr.
Lidestri shall be entitled to receive only the unpaid portion of his monthly
base salary and all vested benefits under any benefit programs, in each case,
through the date of termination. In addition, Mr. Lidestri shall be entitled to
participate in the benefit programs of Interliant for the longer of the
remainder of the term of the Lidestri Agreement or six months from the date of
termination. In the event of termination due to death or disability during the
term of the Lidestri Agreement, Mr. Lidestri or Mr. Lidestri's estate, as
applicable, shall be entitled to receive (i) any and
                                       54
<PAGE>   59
 
all accrued and unpaid portions of his annual base salary to the date of death
or disability and (ii) employee benefits accrued but unpaid to the date of death
or disability.
 
     The Lidestri Agreement includes certain restrictive covenants for the
benefit of Interliant relating to non-disclosure by Mr. Lidestri of Interliant's
confidential business information, non-solicitation of Interliant's customers
and non-competition by Mr. Lidestri with Interliant's business during the term
of the Lidestri Agreement and for a period of time following termination of Mr.
Lidestri's employment with Interliant which shall be either one year from such
termination or two years following the date of the Lidestri Agreement depending
upon the reason for termination.
 
                              CERTAIN TRANSACTIONS
 
     Since Interliant's inception, Web Hosting Organization LLC ("WEB") and
SOFTBANK Technology Ventures and SOFTBANK Technology Advisors Fund L.P. ("the
SOFTBANK Purchasers") have each purchased securities from Interliant. WEB owns
25,200,000 shares of Interliant's common stock which were acquired from
Interliant in a series of six 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 effected in July 1998) of $1.67 per
share. The SOFTBANK Purchasers purchased from Interliant an aggregate of
2,647,658 shares of Interliant's redeemable convertible preferred stock and
warrants to purchase 749,625 shares of Interliant's common stock for an
aggregate purchase price of $13.0 million. The principal members of WEB are
Charterhouse Equity Partners III, L.P. ("CEP III") and WHO Management LLC
("WHO"). Leonard J. Fassler and Bradley A. Feld, Interliant's Co-Chairmen, are
the member managers of WHO. Bradley A. Feld is a Managing Director of the
SOFTBANK Purchasers. See "Description of Capital Stock -- The WEB Hosting
Investment" and " -- The SOFTBANK Investment."
 
     Pursuant to the terms of the Limited Liability Company Agreement of WEB
dated as of November 26, 1997, as amended by Amendment No. 1, dated as of March
4, 1998, (the "WEB LLC Agreement") the members of WEB shall be entitled to
receive a distribution of all cash funds or other property of WEB available from
any source other than the ordinary operations of its subsidiaries, after payment
of all expenses of WEB due at the time of such distribution ("Total Proceeds").
The Total Proceeds shall be distributed to the members of WEB in tranches with
priority given to covering members' federal tax liability, followed by return of
capital and then to achieve specified internal rates of return. The management
distribution to WHO increases as the members of WEB realize these specified
internal rates of return on their investment in WEB. Certain members of
Interliant's senior management may receive distributions from WHO which are
based upon the amount of Total Proceeds received by WHO. As a result, certain
members of senior management may be deemed to have a direct and/or indirect
beneficial interest in WHO. No Total Proceeds have been distributed to date.
 
     During 1998, in connection with certain of our acquisitions, Interliant
paid or accrued transaction fees of approximately $319,000 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
Interliant) to pay Charterhouse two percent (2%) of the total transaction costs
of each acquisition or investment by WEB or its affiliates (which includes
Interliant) in which Charterhouse or any of its affiliates directly or
indirectly provide all or a portion of the equity financing therefor.
 
     During 1998, we paid consulting fees of $120,000 to each of Sage Equities,
Inc. and Intensity Ventures Inc, whose principals are Messrs. Fassler and Feld,
respectively, pursuant to consulting agreements with each of them. Effective
January 1, 1999, Interliant entered into employment agreements with Messrs.
Fassler, Maggs and Bhargava and a consulting agreement with Mr. Feld, through
Intensity Ventures, Inc., pursuant to which each will be paid annual
compensation of $180,000. See "Management -- Employment Agreements."

     The following summary description of Interliant's capital stock does not
purport to be complete and is subject to, and qualified in its entirety by

     The authorized capital stock of Interliant consists of 100,000,000 shares
of common stock, par value $0.01 per share (the "Common Stock"), and
          shares of undesignated preferred stock, par value $0.01 per share (the
"Preferred Stock").
 
COMMON STOCK
 
     As of the date of this prospectus, and including 2,647,658 shares of Common
Stock to be issued upon the conversion of all outstanding Series A Redeemable
Convertible Preferred Stock upon the consummation of this offering (see "-- The
SOFTBANK Investment"), there are                shares of Common Stock
outstanding, held of record by                holders. All outstanding shares of
Common Stock are, and the shares of Common Stock offered hereby will be, when

     The holders of Common Stock will possess exclusive voting rights in
Interliant, except to the extent that the Board shall have designated voting
power with respect to any issued and outstanding Preferred Stock. Each holder of
Common Stock is entitled, on each matter submitted for a vote of holders of
Common Stock, to one vote for each share of such stock registered in such
holder's name on the books of Interliant. Except as otherwise required by law
and subject to the rights of any holders of Preferred Stock, the presence in
person or by proxy of the holders of record of a majority of the shares entitled
to vote at a meeting of stockholders constitutes a quorum for the transaction of
business at that meeting. Actions requiring approval of stockholders will
generally require approval by a majority vote at a meeting at which a quorum is
present, except that at each stockholder meeting for the election of directors,
provided a quorum is present, directors will be elected by a plurality of votes
validly cast in the election. Stockholders will not have any right to cumulate
votes in the election of directors. Certain stockholders of Interliant have been
given the right to nominate persons for election as directors. See "-- The
SOFTBANK Investment" and "-- The Interliant Acquisition."
 
     In the event of liquidation, dissolution or winding up of Interliant, the
holders of the Common Stock will be entitled to share ratably in the
distribution of all assets of Interliant remaining after payment of all of
Interliant's debts and liabilities and of all sums to which holders of any
Preferred Stock may be entitled. Holders of the Common Stock will not generally
be entitled to conversion, preemptive or other subscription rights with respect
to any shares of capital stock which may be issued by Interliant, and there are
no redemption or sinking fund provisions applicable to the Common Stock.
 
PREFERRED 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 "-- The SOFTBANK Investment"), there are no shares of Preferred Stock
issued or outstanding. The Preferred Stock may be issued by the Board in one or
more series and may have such voting rights, if any, designations, preferences
and other special rights and such qualifications, limitations and restrictions,
as the Board (or a duly authorized committee thereof) may fix by resolution or
resolutions. Moreover, the Board may issue such Preferred Stock, from time to
time, in transactions without the approval of the stockholders of Interliant,
and the preferences, designations, voting and other rights of any
 
                                       58
<PAGE>   63
 
such shares of Preferred Stock may materially limit or qualify the rights of the
outstanding shares of Common Stock.
 
     The holders of Preferred Stock may be given the right to vote for the
election of directors generally or to elect a specified number or percentage of
the members of the Board. The number of directors that may be elected by the
holders of any class or series of Preferred Stock having the right to elect
directors may be in addition to the number of directors fixed by or pursuant to
the Amended and Restated Certificate.
 
     One of the effects of undesignated Preferred Stock may be to enable the
Board to render more difficult or to discourage an attempt to obtain control of
Interliant by means of a tender offer, proxy contest, merger or otherwise, and
thereby to protect the continuity of Interliant's management. The issuance of
shares of Preferred Stock pursuant to the Board's authority described above may
adversely affect the rights of the holders of Common Stock. For example,
Preferred Stock issued by Interliant may rank prior to the Common Stock as to
dividend rights, liquidation preference or both, may have full or limited voting
rights and may be convertible into shares of 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.
 
COMMON STOCK WARRANTS
 
     Interliant has warrants outstanding for the purchase of 749,625 shares of
Common Stock at an exercise price of $6.67 per share. Warrants to purchase
735,532 shares of Common Stock at an exercise price of $6.67 per share were
issued to SOFTBANK Technology Ventures IV, L.P. and warrants to purchase 14,093
shares of Common Stock at an exercise price of $6.67 per share were issued to
SOFTBANK Technology Advisors Fund, L.P., each in connection with a Securities
Purchase Agreement dated as of January 28, 1999 between Interliant and the
SOFTBANK Purchasers. Such warrants are immediately exercisable and expire on the
earlier of (i) the date three years following the closing of the offering
contemplated by this prospectus and (ii) January 28, 2003. The exercise price
and number of shares of Common Stock issuable upon exercise of the
aforementioned warrants are subject to adjustment upon the occurrence of certain
events, including stock splits, stock dividends or other distributions,
reorganizations, recapitalizations, mergers, consolidations or sales. The shares
of Common Stock issuable upon exercise of the warrants are subject to certain
registration rights as described under "-- Registration Rights of Certain
Holders" below.
 
THE WEB HOSTING ORGANIZATION INVESTMENT
 
     WEB owns 25,200,000 shares of Common Stock, approximately      % of
Interliant's outstanding Common Stock following consummation of the offering
contemplated by this prospectus, acquired in accordance with a Subscription
Agreement dated as of December 8, 1997 between Interliant and WEB for an
aggregate purchase price of $42,000,000 (the "WEB Hosting Organization
Investment"). The shares were acquired 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 principal members of WEB are (i) CEP III, which is
an affiliate of Charterhouse and (ii) WHO (collectively with CEP III, the "WEB
Members"), of which Leonard J. Fassler and Bradley A. Feld are the member
managers. WHO is the Managing Member of WEB under the terms of WEB's Limited
Liability Company Agreement. 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. Pursuant to an
agreement dated November 26, 1997 among CEP III, Leonard J. Fassler and Bradley
A. Feld, the Board of Directors of Interliant will initially consist of three
designees of WHO and four designees of CEP III. The WHO designees are currently
Leonard J. Fassler, Bradley A. Feld and Stephen W. Maggs, and the CEP III
designees are currently Merril M. Halpern, Thomas C. Dircks, Patricia A. M.
Riley and Jay M. Gates. All of the CEP III designees are directors and/or
officers of Charterhouse. Pursuant to that agreement, unless CEP III and the
member managers agree, the only business Interliant will be involved in will be
acquiring and operating businesses in the Web hosting industry. WEB has certain
demand and incidental registration rights under the terms of (i) that certain
Investors Agreement dated as of January 28,
 
                                       59

1999 by and among Interliant, the SOFTBANK Purchasers and WEB (the "Investors
Agreement") and (ii) that certain Registration Rights Agreement dated as of
December 8, 1997 between Interliant and WEB (the "Registration Rights
Agreement"). See "-- Registration Rights of Certain Holders."
 
THE SOFTBANK INVESTMENT
 
     On January 28, 1999, the SOFTBANK Purchasers purchased from Interliant an
aggregate of 2,647,658 shares of Redeemable Convertible Preferred Stock and
warrants to purchase 749,625 shares of Common Stock for an aggregate purchase
price of $13,000,000 (the "SOFTBANK Investment"). Upon the consummation of the
offering contemplated by this prospectus, all of the outstanding shares of
Redeemable Convertible Preferred Stock will automatically and without further
required action be converted into an equal number of shares of Common Stock, and
the SOFTBANK Purchasers will own approximately      % of Interliant's
outstanding Common Stock. Bradley A. Feld, Co-Chairman and a director of
Interliant, is a general partner of the SOFTBANK Purchasers. See "Certain
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 as a director of Interliant and have the Board cause that
director to be a member of the Compensation Committee and/or the Audit Committee
of the 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 the Board of Directors of Interliant pursuant to
such provisions.
 
THE INTERLIANT ACQUISITION
 
     On March 10, 1999, pursuant to an Asset Purchase Agreement (the "Purchase
Agreement") by and among Interliant, (formerly Sage Networks, Inc.), Interliant
Texas and the shareholders of Interliant Texas (the "Seller Shareholders"),
Interliant (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 3,608,863 shares of Common Stock to be delivered at
the closing of the acquisition to Seller Shareholders, 114,644 shares of Common
Stock to be delivered at the closing of the acquisition to another entity,
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 the
Seller Shareholders under the Purchase Agreement. Unless Interliant makes 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 Seller Shareholders, on March 31, 2000.
 
     In addition, under the Purchase Agreement, Interliant issued        options
to purchase shares of Common Stock ("Interliant Options") of Interliant 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 the Shareholders of Interliant (the "Shareholders Agreement"). See
"-- Registration Rights of Certain Holders."
 
                                       60
<PAGE>   65
 
     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 the
Interliant 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 as a director of Interliant. To date, such parties have not exercised
such rights.
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
     The holders of an aggregate of 27,847,658 shares of Common Stock and
749,625 shares of Common Stock issuable upon the exercise of warrants have been
granted by Interliant certain demand and incidental registration rights. The
SOFTBANK Purchasers have such registration rights under the Investors Agreement
with respect to (i) 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 (ii) 749,625 shares of Common
Stock receivable upon the exercise of warrants, each purchased as part of the
SOFTBANK Investment. 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 as part of the WEB Hosting
Organization Investment. The Seller Shareholders have such 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 such rights with respect to
114,644 shares owned by it. The Shareholders Agreement provides that it shall be
amended as necessary to include any additional shares of Common Stock issuable
pursuant to the provisions in the Purchase Agreement regarding adjustment of
purchase price.
 
     In general, the holders of the aforementioned registration rights are
entitled, if Interliant proposes (including in connection with any registration
request by another stockholder) to file a registration statement under the
Securities Act covering its Common Stock or any securities exercisable or
exchangeable for or convertible into its Common Stock (with the exception of an
offering pursuant to a registration statement on Form S-4 or Form S-8 or similar
forms in connection with an exchange offer or any offering of securities solely
to Interliant's existing stockholders or employees of Interliant and its
subsidiaries and other than in connection with the offering contemplated by this
prospectus), to require Interliant to include a requested amount of their Common
Stock in Interliant's registered offering on the same terms and conditions
applicable to the other equity securities included in such registration
statement (a "Piggyback Registration Right"), subject to reduction if the
managing underwriter determines that the inclusion of such shares would
materially and adversely affect the success of this offering. Interliant can be
required to maintain the effectiveness of the registration statement until the
earlier of (i) 180 days after its effective date or (ii) consummation of the
distribution of Common Stock by the stockholders whose shares of Common Stock
are included in such registration statement.
 
     In addition to Piggyback Registration Rights, the holders of the
aforementioned registration rights other than the Seller Shareholders and
Broadview Holdings LLP are also entitled to require Interliant 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 its best efforts to register such shares under
the Securities Act of 1933, as amended (a "Demand Registration Right"), subject
to reduction based on the advice of the managing underwriter. A majority in
interest 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 in interest 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 Interliant becomes 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, Interliant is not obligated to effect Demand
Registration Rights at any time prior to the date six months following the
consummation of the offering contemplated by this prospectus, and Interliant may
also defer the effective date of a Demand Registration Right for a period of up
to 180 days under certain circumstances involving undisclosed material corporate
developments or transactions.
 
     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,
                                       61
<PAGE>   66
 
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. Interliant is 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 of Interliant in connection with the acquisition
of substantially all of the assets of Clever Computers, Inc. by Interliant,
Interliant agreed that in the event it grants 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
 
     Interliant's Amended and Restated Certificate contains a provision that is
designed to limit the directors' liability to the extent permitted by the
Delaware General Corporation Law and any amendments thereto. Specifically,
directors will not be held liable to Interliant or its stockholders for an act
or omission in such capacity as a director, except for liability as a result of:
(i) a breach of the duty of loyalty to Interliant or its stockholders, (ii) acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) payment of an improper dividend or improper
repurchase of Interliant's stock under Section 174 of the Delaware General
Corporation Law, or (iv) actions or omissions pursuant to which the director
received an improper personal benefit. The principal effect of the limitation on
liability provision is that a stockholder is unable to prosecute an action for
monetary damages against a director of Interliant unless the stockholder can
demonstrate one of the specified bases for liability. This provision, however,
does not eliminate or limit director liability arising in connection with causes
of action brought under the federal securities laws. Interliant's Amended and
Restated Certificate does not eliminate its directors' duty of care. The
inclusion of this provision in Interliant's 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 Interliant and its
stockholders. This provision should not affect the availability of equitable
remedies such as injunction or rescission based upon a director's breach of the
duty of care.
 
     The By-laws also provide that Interliant will indemnify its directors and
officers to the fullest extent permitted by Delaware law. Interliant is
generally required to indemnify its 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 Interliant or another entity that the director or officer serves
at Interliant's request, subject to certain conditions, and to advance funds to
its directors and officers to enable them to defend against such proceedings. To
receive indemnification, the director or officer must have been successful in
the legal proceeding or acted in good faith and in what was reasonably believed
to be a lawful manner in Interliant's best interest.
 
DELAWARE ANTI-TAKEOVER LAW
 
     Interliant is subject to the provisions of Section 203 of the Delaware
General Corporation Law ("Section 203"). Section 203 prohibits an "interested
stockholder" of a Delaware corporation from engaging in certain business
combinations with the corporation, including mergers or consolidations or
acquisitions of additional shares of the corporation, for a period of three
years following the time that the stockholder becomes an "interested
stockholder." An "interested stockholder" is defined to include persons owning
directly or indirectly 15% or more of the outstanding voting stock of a
corporation. The prohibitions under Section 203 are not applicable in certain
circumstances, including those in which (i) the business combination or the
transaction which results in the stockholder becoming an "interested
stockholder" is approved by the corporation's board of directors prior to the
time the stockholder becomes an "interested stockholder", (ii) the "interested
stockholder" upon consummation of such transaction owns at least 85% of the
voting stock of the corporation outstanding prior to such transaction, (iii) at
or subsequent to the time the stockholder becomes
                                       62
<PAGE>   67
 
an "interested stockholder", the business combination is approved by the
corporation's board of directors and authorized at an annual or special meeting
of stockholders by an affirmative vote of two-thirds of the outstanding voting
stock which is not owned by the "interested stockholder" or (iv) the corporation
has elected not to be governed by such prohibitions. The Board approved (i) the
acquisition of Common Stock by WEB as part of their approval of WEB Hosting
Organization Investment and (ii) the acquisition of Preferred Stock and warrants
by the SOFTBANK Purchasers as part of their approval of the SOFTBANK Investment
and, accordingly, the prohibitions under Section 203 will not apply to any
business combination with either WEB or the SOFTBANK Purchasers.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is                .
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, Interliant will have
shares of Common Stock outstanding (assuming no exercise of outstanding stock
options after                , 1998). Of these shares, the                shares
of Common Stock sold in this offering will be freely tradable without
restriction under the Securities Act, except that any shares purchased by
"affiliates" of Interliant ("Affiliates"), as that term is defined in Rule 144
("Rule 144") under the Securities Act, generally may be sold only in compliance
with the limitations of Rule 144 described below.
 
SALES OF RESTRICTED SECURITIES
 
     The remaining                shares of Common Stock outstanding upon
completion of this offering are deemed "Restricted Shares" under Rule 144. Of
the Restricted Shares, up to                shares will be eligible for sale in
the public market after this offering pursuant to Rule 144(k) under the
Securities Act; of these shares are subject to the 180-day Lock-up Agreements
described below, but will be eligible for sale in the public market beginning
180 days after the closing of this offering. Of the remaining Restricted Shares
outstanding,                shares will be eligible for resale under Rule 144
commencing 90 days after the date of this prospectus;                of these
shares are subject to the 180-day Lock-up Agreements.
 
     In general, under Rule 144 as currently in effect, a holder of Restricted
Shares who beneficially owns shares that were not acquired from Interliant or an
Affiliate within the previous one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of one
percent of the then outstanding shares of Common Stock (approximately shares
immediately after this offering) or the average weekly trading volume of the
Common Stock in the over-the-counter market during the four calendar weeks
preceding the date on which notice of the sale is filed with the Securities and
Exchange Commission. Sales under Rule 144 are subject to certain manner of sale
provisions, notice requirements and the availability of current public
information about Interliant. A person who is not deemed an Affiliate of
Interliant at any time during the three months preceding a sale and who
beneficially owns shares that were not acquired from Interliant or an Affiliate
within the previous two years is entitled to sell such shares under Rule 144(k)
without regard to volume limitations, manner of sale provisions, notice
requirements or the availability of current public information concerning
Interliant. In addition, Interliant's employees, directors, officers or
consultants who were issued shares pursuant to a written compensatory plan or
contract may be entitled to rely on the resale provisions of Rule 701 which
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, and permits affiliates to sell their Rule 701 shares
without having to comply with Rule 144's holding period restrictions, in each
case commencing 90 days after the date of this prospectus.
 
OPTIONS
 
     Interliant intends 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 pursuant to Interliant's
stock option plans. Shares covered by these registration statements will
thereupon be
                                       63
<PAGE>   68
 
eligible for sale in the public markets, subject to the 180-day Lock-up
Agreements described below, to the extent applicable.
 
LOCK-UP AGREEMENTS
 
     Interliant and Interliant's executive officers and directors and all
existing stockholders have agreed, not to directly or indirectly (i) offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant for
the sale of or otherwise dispose of or transfer any shares of Common Stock or
securities convertible into or exchangeable or exercisable for or repayable with
Common Stock, whether now owned or thereafter acquired by the person executing
the agreement or with respect to which the person executing the agreement
thereafter acquires the power of disposition, or file a registration statement
under the Securities Act with respect to the foregoing; (ii) enter into any swap
or other agreement that transfers, in whole or in part, the economic consequence
of ownership of the Common Stock whether any such swap or transaction is to be
settled by delivery of Common Stock or other securities, in cash or otherwise;
or (iii) make any demand for, or exercise any right with respect to, the
registration of any share of Common Stock or any securities convertible into or
exchangeable for Common Stock, without the prior written consent of Merrill
Lynch on behalf of the Underwriters for a period of 180 days after the date of
this prospectus. Notwithstanding the foregoing, the stockholders of Interliant
may (i) transfer the securities to a third party as a bona fide gift; provided
that any donee agrees to be bound by the provisions of the agreement or (ii)
pledge their securities to Interliant in consideration for a loan from
Interliant.
 
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
Interliant's future ability to raise capital through an offering of equity
securities.

     In the Purchase Agreement, the several 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 Purchase Agreement provides that, in certain
circumstances, the purchase commitments of the nondefaulting Underwriters may be
increased or the Purchase Agreement may be terminated. The closing with respect
to the sale of shares of Common Stock to be purchased by the Underwriters are
conditioned upon one another.
 
     The Representatives have advised Interliant that the 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 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.
 
     Interliant has granted options to the Underwriters, exercisable for 30 days
after the date of this prospectus, to purchase up to an aggregate of additional
shares of Common Stock at the public offering price set forth on the cover page
of this prospectus, less the underwriting discount. The Underwriters may
exercise these options solely to cover over-allotments, if any, made on the sale
of the Common Stock offered hereby. To the extent that the Underwriters exercise
these options, each Underwriter will be obligated, subject to certain
conditions, to purchase a number of additional shares of Common Stock
proportionate to such Underwriter's initial amount reflected in the foregoing
table.
 
     The following table shows the per share and total public offering price,

options.

     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.
 
     At the request of Interliant, the Underwriters have reserved for sale, at
the initial public offering price, up to                of the shares offered
hereby to be sold to certain directors, officers, employees, distributors,
dealers, business associates and related persons of Interliant. The number of
shares of Common Stock available for sale to the general public will be reduced
to the extent such 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.
 
     Interliant and Interliant's executive officers and directors and all
existing stockholders have agreed, subject to certain exceptions, not to
directly or indirectly (i) offer, pledge, sell, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant
any option, right or warrant for the sale of or otherwise dispose of or transfer
any shares of Common Stock or securities convertible into or exchangeable or
exercisable for or repayable with Common Stock, whether now owned or thereafter
acquired by the person executing the agreement or with respect to which the
person executing the agreement thereafter acquires the power of disposition, or
file a registration statement under the Securities Act with respect to the
foregoing; (ii) enter into any swap or other agreement that transfers, in whole
or in part, the economic consequence of ownership of the Common Stock whether
any such swap or transaction is to be settled by delivery of Common Stock or
other securities, in cash or otherwise; or (iii) make any demand for, or
exercise any right with respect to, the registration of any share of Common
Stock or any securities convertible into or exchangeable for Common Stock,
without the prior written consent of Merrill Lynch on behalf of the Underwriters
for a period of 180 days after the date of this prospectus. Notwithstanding the
foregoing, the stockholders of Interliant may (i) transfer the securities to a
third party as a bona fide gift; provided that any donee agrees to be bound by
the provisions of the agreement or (ii) pledge their securities to Interliant in
consideration for a loan from Interliant. See "Shares Eligible for Future Sale."
 
     Prior to this offering, there has been no public market for the Common
Stock of Interliant. The initial public offering price will be determined
through negotiations between Interliant and the Representatives. The factors to
be considered in determining the initial public offering price, in addition to
prevailing market conditions, are expected to be price-earnings ratios of
publicly traded companies that the Representatives believe to be comparable to
Interliant, certain financial information of Interliant, the history of, and the
prospects for, Interliant and the industry in which it competes, and an
assessment of Interliant's management, its past and present operations, the
prospects for, and timing of, future revenues of Interliant, and the present
state of Interliant's development. There can be no assurance that an active
trading market will develop for the Common Stock or that the 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 hereby.
 
     The Underwriters do not intend to confirm sales of the Common Stock offered
hereby to any accounts over which they exercise discretionary authority.
 
     Interliant has agreed to indemnify the Underwriters against certain
liabilities, including certain liabilities under the Securities Act, or to
contribute to payments the Underwriters may be required to make in respect of
this offering.
 
     Until the distribution of the Common Stock is completed, rules of the
Securities and Exchange Commission (the "Commission") may limit the ability of
the Underwriters and certain selling group members to bid for and purchase the
Common Stock. As an exception to these rules, the Representatives are permitted
to engage in certain transactions that stabilize the price of the Common Stock.
Such transactions consist of bids or purchases for the purpose of pegging,
fixing or maintaining the price of the Common Stock.

     If the Underwriters create a short position in the Common Stock in
connection with the offering contemplated hereby, i.e., if they sell more shares
of Common Stock than are set forth on the cover page of this prospectus, the
Representatives may reduce that short position by purchasing Common Stock in the
open market. The Representatives may also elect to reduce any short position by
exercising all or part of the over-allotment options described above.
 
     The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Common Stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the 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 the Common Stock to the extent that it
discourages resales of the Common Stock.
 
     Neither Interliant 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 the Common Stock. In addition, neither
Interliant nor any of the Underwriters makes any representation that the
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 Interliant 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.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
Sage Networks, Inc.
 
     We have audited the accompanying consolidated balance sheets of 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
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
                               DECEMBER 31, 1998
 
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, Sage Networks Acquisition Corp. and B.N.
Technology, Inc., dba ICOM. All significant intercompany accounts and
transactions have been eliminated.
 
  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.
 
  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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  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              3 years
  equipment...............................
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 two to ten years (see Note 4).
 
  Impairment of Long-Lived Assets
 
     The Company continually reviews the carrying value of long-lived assets,
including furniture, fixtures and equipment, and intangible assets to determine
whether there are any indications of 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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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 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. 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.

</TABLE>
 
     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

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.
 
          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. 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

     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 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. 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, 1998, 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, 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.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
     During the period from inception through March 10, 1999, Sage Networks Inc.
("Sage" 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 balance sheet assumes that
acquisitions completed in 1999 occurred on December 31, 1998, and includes the
December 31, 1998 historical consolidated balance sheets of Sage and the
acquired businesses adjusted for the pro forma effects of these acquisitions,
including the payment of approximately $8.0 million of Interliant Texas' short
term notes payable on the date of the closing of the transaction. The unaudited
pro forma consolidated statement of operations for the year ended December 31,
1998 assumes that the acquisitions completed in 1998 and 1999 had occurred on
January 1, 1998, and includes the historical consolidated statements of
operations of Sage, adjusted for the pro forma effects of the acquisitions. The
unaudited pro forma consolidated balance sheet also reflects the sale in January
and February 1999 of the Series A Redeemable Convertible Preferred Stock and the
purchase of Common Stock by Web Hosting Organization LLC. (See notes 5 and 12 of
notes to the consolidated financial statements)
 
     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 Sage, 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 Sage believes are reasonable in the circumstances. The actual
adjustments may be revised upon completion of the purchase price allocations.

                         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.
 
  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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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, 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

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

                          INDEPENDENT AUDITOR'S REPORT
 
Board of Directors
B.N. Technology, Inc.
dba Internet Communications
Los Angeles, California
 
     We have audited the accompanying balance sheets of B.N. Technology, Inc.
dba Internet Communications as of December 31, 1996 and 1997, and the related
statements of operations and accumulated deficit, and cash flows for the period
April 15, 1996 (inception) through December 31, 1996 and for the year ended
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
ended December 31, 1997.

                         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.

     The Company's management believes that all information technology included
in the operating system, together with all products and services provided to its
customers or for internal use, in coordination with technology shared with
customers, suppliers or vendors, will accurately process transactions from 1999
and through the Twenty-First Century, including leap year calculations. Neither
performance nor functionality of such technology will be affected by the year
2000 issue.

                          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.

     We have audited the accompanying combined balance sheet of Telephonetics

combined statements of operations, capital deficit and cash flows for each of
the two years in the period then ended. These combined financial statements are
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.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of Telephonetics

                   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.

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
payment in 2004. However, NDA is only obligated to make payments, subject to
certain limitations, based on net profit as of the end of the fiscal year
preceding the relevant payment date. The note payable has an attached interest
rate of prime plus 1% (8.75% at December 31, 1998). The principal balance is
increased annually for the accrual of interest. The note payable is secured on a
pro rata basis by a security

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

                 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
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.

</TABLE>
 
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.
 
     A summary of the Option Plan as of December 31, 1996, 1997, and 1998 and
changes during the years ended on those dates are as follows:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     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:

</TABLE>
 
     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.
 
9.  COMMITMENTS AND CONTINGENCIES
 
     The Company leases various office space and equipment under noncancelable
operating leases expiring on various dates through 2001, generally with options
to renew under terms consistent with the original leases. The gross balance of
assets recorded under capital leases which are included in property and
equipment at December 31, 1997 and 1998 was approximately $287,000 and $291,000,
respectively. Associated accumulated depreciation was approximately $95,000 and
$165,000 at December 31, 1997 and 1998, respectively. At December 31, 1998,
future lease payments are as follows:

     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.
 
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 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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  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.

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>   170
 
     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

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.

ITEM 17.  UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes to provide to the
underwriters, at the closing specified in the underwriting agreement,
certificates in such denominations and registered in such names as required by
the underwriters to permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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.

                 CERTAIN COVENANTS OF THE COMPANY AND THE BUYER

         SECTION 1. NON-COMPETITION; NON-SOLICITATION. (A) Covenant of the
Company.

         (1) For a period commencing on the Closing Date and ending on the third
anniversary of the Closing Date (the "Non-Competition Period"), neither the
Company nor any successor thereto or acquiror of substantially all of the equity
or assets thereof shall engage in any capacity in an Internet Web hosting
business which is similar to or in competition with the Business. The parties
understand and specifically acknowledge that the Business operates world-wide
and its location is not limited to a specific geographical area. For this
reason, the parties agree that the Company's agreement not to compete in
accordance with this Article II, Section 1 is not limited to any specific
geographical area but is world wide. Notwithstanding the foregoing, the Company
may, during the Non-Competition Period or thereafter:

                  (a) acquire, merge with or into or be acquired by (a "Business
         Combination") any business entity which engages in the Internet Web
         hosting business, so long as the Company offers, or causes the
         successor in such Business Combination to offer (x) to sell, transfer
         or assign to Buyer (in either case, free and clear of all liens and
         encumbrances) all of the Web hosting customer base of such entity
         (other than customers that are Financial Services Companies) at a
         purchase price equal to 20% of the gross revenues of such acquired Web
         hosting customer base during the five year period following the date of
         the consummation of such Business Combination (which purchase price
         shall be payable by the Buyer quarterly in arrears during such five
         year period) and otherwise on customary terms and conditions for such a
         sale, transfer or assignment or (y) to the extent that such web hosting
         customer base cannot legally be sold, transferred or assigned, to enter
         into a Co-location Agreement with the Buyer with respect to such Web
         hosting customer base pursuant to which the Buyer shall receive 80% of
         the gross revenues of such acquired Web hosting customer base during
         the five year period following the date of the consummation of such
         Business Combination (which payments shall be made to the Buyer
         quarterly in arrears during such five year period) and otherwise on
         customary terms and conditions for such a Co-location Agreement ((x)
         and (y) shall collectively be referred to as the "Offer"); provided,
         however, that the Company shall not be required to make an Offer with
         respect to any Web hosting business that solely serves Financial
         Services Companies (as hereinafter defined);

                  (b) to engage in a Web hosting business that solely serves
         Financial Services Companies; or

                  (c) be acquired by or merge with a business entity that is a
         public company with a market cap in excess of $100,000,000.

Offer to the Buyer by written notice (the "Offer Notice"). The Offer Notice
shall set forth the name of the owner of the Web hosting business that is the
subject of the Offer, the annual revenues from the Web hosting customer base to
be acquired (determined in accordance with Article II, Section 1(1)(a)) and the
other material terms and conditions thereof. The Buyer may accept any Offer
within thirty (30) days of receipt of the Offer Notice. If Buyer accepts any
Offer, Buyer shall consummate the acquisition of such Web hosting business on
terms (other than purchase price) no less favorable than those contained in the
Offer Notice within thirty (30) days following the date of acceptance of such
Offer. If the Buyer does not accept any Offer within the required time or does

companies, insurance companies, broker-dealers, securities placement agents,
financial advisory firms, investor relations firms, hedge funds, mutual funds

         (4) Buyer and the Company acknowledge and agree that the damages to
Buyer as a result of the Company entering into any Business Combination in
breach of the provisions of Article II, Section 1(A)(1) of this Agreement cannot
be easily quantified. For this reason, Buyer and the Company expressly agree

breach.

proprietary information of Buyer, Parent or their respective affiliates or make
use of any of such information except in evaluating whether to enter into this
Agreement or unless such information is made public by a source other than the
Company or such disclosure is required by law or regulation or court or
administrative order. In connection with such evaluation, the Company may
disclose such proprietary information to its legal and financial consultants on
a need to know basis on the condition that those consultants are similarly
prohibited from further disclosing such information as provided herein.

second anniversary of the Closing Date, the Company, unless acting with the
express written consent of the Buyer or Parent, will not, directly or
indirectly, interfere with, solicit or endeavor to entice away:

<PAGE>   11
         services with respect to Parent's Internet Web hosting and related
         businesses), the Buyer, the Parent or any of their affiliates during
         the twelve months immediately preceding the date of such solicitation,
         interference or endeavor; or

                  (b) any person or entity who was a customer or client of the
         Company or of the Buyer or of the Parent, or any person or entity who
         requested or received a proposal from Buyer, Parent or the Company,
         with respect to any Internet Web hosting business similar to or in
         competition with the Business in which the Company, Buyer, Parent, or
         any of their affiliates is or has been engaged after the date of this
         Agreement.

         (B) Covenant of the Buyer.

except to the extent the Indemnifying Party is materially prejudiced by such

third party without the prior written consent of the Indemnifying Party, which
will not be unreasonably withheld or delayed, unless suit in respect of such

counsel and its own expense if the Indemnifying Party acknowledges to the
Indemnified Party in writing its obligation to indemnify the Indemnified Party

defense, prosecution and settlement of such action or proceeding. The
Indemnifying Party shall not, in the defense or prosecution of any such action
or proceeding except with the written consent of the Indemnified Party, consent

Indemnified Party from all liability in respect of the matter which is the
subject of such action or proceeding. The Indemnified Party shall cooperate in

pursuant to Article II, Section 2(B) of this Agreement upon the request of the
Buyer. Indemnity claims by Buyer, Parent or any such person shall be satisfied
first from the Security Bond and thereafter by the Company. The Security Bond
does not constitute a limit on the liability of the Company to Buyer, the Parent
or any such person hereunder, it being understood and agreed that the Company
shall remain liable to satisfy the amount of Claims which exceed the amount of
the Security Bond. The Security Bond shall be released on May 1, 1999, to the

         SECTION 2. TRANSITION ASSISTANCE AND ADJUSTMENTS.

customers included on the Customer List (other than the Excluded Customers) that
the Business has been sold to Buyer, including, without limitation, executing

associates of the Business, from maintaining the same business relationships
with Buyer or its successors and/or assigns after the Closing Date as were
maintained with the Company with respect to the Business prior to the Closing
Date.

         (D) The Buyer shall use its reasonable commercial efforts, without

Buyer in accordance with this Agreement. Following the Closing, neither the
Company nor any affiliate of the Company (as defined under federal securities
laws), shall not use the name "HostAmerica" or any confusingly similar name to

understands and agrees (i) that remedies at law for any breach of this Article

breach are not readily susceptible to measurement in monetary terms and (iii)

its counsel with respect to the meaning and effect of this Article IV, Section
2(E).

         SECTION 3. AUDIT OF BUSINESS. The Company shall make available to
Buyer, on the terms and conditions set forth in the Transition Service

               POST CLOSING PURCHASE PRICE ADJUSTMENT. (i) The parties to this
Agreement agree that notwithstanding the Closing Date, revenues and expenses of
the Business should be adjusted as of June 1, 1998. Accordingly, not more than
forty-five (45) days following the Closing Date, the Company shall deliver to
Buyer a statement of revenues (including a statement of the change in the
balance of deferred revenues from June 1, to June 8, 1998) and direct expenses
of the Business (in each case, determined in accordance with generally accepted
accounting principles) for the period from June 1, 1998 to the Closing Date (the
"Closing Statement").

         (ii) Within thirty (30) days after receipt of the Closing Statement,
Buyer shall communicate in writing to Seller any objection or disagreement that
it may have with the Closing Statement (an "Objection"). The Company shall have
fifteen (15) days after receipt of an Objection in which to respond in writing
to such Objection. If, after five (5) days following such fifteen day period,
Buyer and the Company have not resolved the matter in dispute, such matter shall
be submitted to KPMG Peat Marwick (or any other independent certified public
accountants, as Buyer and the Company may agree) for determination. Such
determination shall be made on or prior to the date that is sixty (60) days
following the date of the initial receipt by Buyer of the Closing Statement and
shall be binding on Buyer and the Company (the "Final Determination"). The cost
of such accountants shall be shared equally by the Buyer and the Company.

         (iii) If the revenues (after being adjusted by the change in deferred
revenues) exceed the direct expenses as set forth on the Closing Statement (as
resolved by the Buyer and the Company or as set forth in any Final
Determination), the Company shall pay the amount of such excess to Buyer. If the
direct expenses exceed the revenues (after such adjustment), the Buyer shall pay
the amount of such excess to the Company. Any payment pursuant to this Article
I, Section 2(b) shall be paid within five (5) business days after Buyer's and
the Company's resolution of the Closing Statement or receipt of the Final
Determination, if any.

            (b) Reserved.

            (c) Corporate Authorization. The execution, delivery and performance
by the Seller of the Transaction Documents to which Seller is a party, the Wolf
Notes and the bills of sale, assignments and other instruments of transfer
referred to in this Agreement to which Seller is a party, have been authorized
and approved by all requisite corporate action on the part of Seller, and Seller
has the power and authority to execute, deliver and perform the Transaction
Documents to which it is a party and to consummate the transactions contemplated
thereby, no other corporate or shareholder approval or authorization is required
on the part of Seller, any trustee, any lender to the Seller or any other person
by law or otherwise (except as have been obtained) in order to make the
Transaction Documents to which it is a party, the Wolf Notes and the bills of
sale, assignments and other instruments of transfer referred to in this
Agreement the valid, binding and enforceable obligations of Seller (subject to
the receipt of required consents to assignment of the Assigned Agreements and
the requirements of the HSR Act) except as enforcement thereof may be limited by
bankruptcy, insolvency, or other similar laws affecting the enforcement of
creditors' rights in general or by general principles of equity.

            (d) Purchased Assets; Business.

                  (i) Exhibit 5.01(d)(i) is a substantially accurate and
complete list of the Assigned Agreements, setting forth the name and date of,
and parties to, each such agreement, and indicating whether any consent is
required for the assignment of such agreement by Seller to Buyer, as
contemplated by this Agreement. All material Assigned Agreements (in terms of
both revenues and liabilities) are included in Exhibit 5.01(d)(i). True and
complete copies of the Assigned Agreements have been furnished or made available
to Buyer. The Seller has no material oral business agreements. Except as set
forth on Exhibit 5.01(d)(i), Seller is not in default (and no event or
circumstance exists which, with notice or lapse of time or both, would
constitute a default by Seller) in any material respect under any of the
Assigned Agreements and, to the Knowledge of Seller, no other party to the
Assigned Agreements is in default under such agreements. Each Assigned Agreement
is in full force and effect. Except for Employment Contracts and any consents,
waivers, or approvals required by the terms of the Assigned Agreements, Seller
has the right to assign the Assigned Agreements, and Seller has not otherwise
assigned, pledged or encumbered its interest in the Assigned Agreements except
as set forth in Exhibit 5.01(d)(i). Many Assigned Agreements contain maintenance
or warranty obligations on the part of Seller that under the terms of the
Assigned Agreement are limited to the revenues received by Seller under such
Assigned Agreement. In general, the Assigned Agreements exclude liability for
consequential damages.

                  (ii) Seller does not own any real property. Seller's leasehold
interest in each Site is a valid and subsisting leasehold interest in such Site
pursuant to the Lease applicable thereto, and such Lease affords the tenant
thereunder the legal right to occupy such Site as of the Closing Date in
accordance with the terms thereof. Each Lease is valid and enforceable by Seller
except as enforcement thereof may be limited by bankruptcy, insolvency, or other
similar laws affecting the enforcement of creditors' 


                                       5
<PAGE>   10

rights in general or by general principles of equity. Seller has performed, in
all material respects, all the obligations required to be performed by it under
each Lease and possesses and quietly enjoys the premises under each Lease.
Seller has not received notice of any pending or threatened condemnation
proceedings relating to all or any portion of the property or premises that are
the subject of any Lease and, to Seller's Knowledge, there are no such pending
or threatened proceedings.

                  (iii) Seller has good and marketable title to the Customer
Data and Fixed Assets owned by it and to the Receivables, Fixed Assets and Cash,
in each case, free and clear of all Encumbrances except those listed on Exhibit
5.01(d)(iii). The Receivables arose in the ordinary course of business of Seller
and constitute valid claims against the account debtors with respect thereto.
The Fixed Assets are in good and working condition, reasonable wear and tear and
obsolescence excepted.

                  (iv) Exhibit 5.01(d)(iv) sets forth the nature of the
operations at each Site and lists the Receivables as of February 28, 1999, Fixed
Assets as of February 28, 1999 and Other Property as of February 28, 1999. All
such property is located at the Sites or is in the possession of Employees of
the Seller.

                  (v) The Purchased Assets include all of the assets of Seller
used by Seller to conduct the Business as of the Closing Date consistent with
past practice (subject to Section 8.02 and other than the Excluded Assets).

            (e) Litigation. Except as set forth in Exhibit 5.01(e), there is no
litigation, action, suit, tax audit, proceeding or to the Knowledge of the
Seller, investigation pending or, to Seller's Knowledge, threatened with respect
to the Business, any of the Purchased Assets or any of the transactions
contemplated hereby before or by any Federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality,
or any other entity, which, if adversely determined, could reasonably be
expected to have a material adverse effect upon the Purchased Assets taken as a
whole or the conduct by Buyer after the Closing Date of a business at the Sites
substantially similar to the Business. Seller is not in default with respect to
any order, writ, injunction or decree of any court or Federal, state, municipal
or other governmental department, commission, board, bureau, agency or
instrumentality which, if not cured, could reasonably be expected to have a
material adverse effect upon the Purchased Assets taken as a whole or the
conduct by Buyer after the Closing Date of a business at the Sites substantially
similar to the Business.

            (f) No Conflict. Except as set forth in Exhibit 5.01(f), the
execution by Seller of the Transaction Documents to which it is a party, the
Wolf Notes and the bills of sale, assignments and other instruments of transfer
referred to in this Agreement, in each case, to which it is or will be a party,

agreements to which Seller will be a party and the consummation by Seller of the
transactions contemplated hereby or thereby (i) will not violate in any material
respect any provision of applicable law to which Seller is subject, (ii) subject
to required consents to assignment of Assigned Agreements will not conflict with
any provision of the Articles of Incorporation or Bylaws of Seller or conflict

default) under, or result in the termination of, or accelerate the performance
required by any of the terms, conditions or provisions of any contract,
agreement or other instrument binding on Seller, which conflict, default,
termination or acceleration would prevent, delay or impair Seller's ability to
consummate the transactions contemplated by this Agreement or have a material
adverse effect on Buyer, Sage or the Business, (iii) will not result in the
creation of any Encumbrance upon any of the Purchased Assets, (iv) do not
require the consent or approval of, or registration, declaration or filing with,
any court, administrative agency or commission or other governmental authority
or instrumentality, except for any filings under state laws required in

Act, and (v) do not violate any order, writ, injunction, decree, arbitral award,
statute, rule or regulation applicable to Seller, to any of the Purchased Assets
or to the Business of Seller, violation of which would prevent, delay or impair
Seller's ability to consummate the transactions contemplated by this Agreement
or have a material adverse effect upon Buyer or Sage or the conduct by Buyer or
Sage after the Closing Date of a business substantially similar to the Business.

            (g) No Other Agreements to Sell Assets or Business. Except as set
forth in Exhibit 5.01(g), Seller does not have any legal obligation, absolute or
contingent, to any other person or firm to sell the assets of Seller (other than

effect any merger, consolidation or other reorganization of Seller or to enter
into any agreement with respect thereto.

                  (ii) From and after the Closing Date to and including the date
two years following the Closing Date, Seller will not, unless acting with the
express written consent of Sage, directly or indirectly, solicit or interfere
with, or endeavor to entice away (x) any person who was employed by Seller or
Sage or any subsidiaries thereof, (y) any person who otherwise performed
services (other than legal, accounting, consulting or financial advisory
services) on a regular basis for Seller or Sage or any subsidiaries thereof or

the date hereof up to and including the Closing Date, permit Buyer and Buyer's
attorneys, accountants, agents and representatives full access to the books,
records, business and assets of Seller at any reasonable time and in any
reasonable manner on reasonable advance notice and in a manner that does not

action, or by inaction, permit an event to occur, which would result in any of
the representations and warranties of Seller or Shareholders herein contained

each Shareholder shall promptly give written notice to Buyer upon becoming aware
of (A) any fact which, if known on the date hereof, would have been required to
be set forth or disclosed pursuant to this Agreement, and (B) any impending or
threatened breach in any material respect of any of the representations and
warranties contained in this Agreement and with respect to the latter shall use
all reasonable efforts to remedy same.

            (f) Mutual Cooperation. The parties hereto will cooperate with each
other, and will use all commercially reasonable efforts to cause the fulfillment
of the conditions to the parties' obligations hereunder and to obtain as
promptly as possible all consents, authorizations, orders or approvals from each

with the transactions contemplated by this Agreement.

            (g) Further Assurances. Seller and Shareholders will cooperate fully
with Buyer and Sage in connection with the transactions contemplated by this
Agreement. Without limiting the generality of the foregoing, from and after the
Closing Date, from time to time, at the request of Buyer or Sage and without
further consideration, Seller and Shareholders will execute and deliver such
other instruments, including powers of attorney, and take such other action as
Buyer or Sage may reasonably request to more effectively put Buyer or Sage in
possession and operating control of all or any part of the Purchased Assets and
Assumed Liabilities.

            (h) No Mergers, Consolidations, Sales of Assets, Etc. Until the
earlier of the consummation of the transactions contemplated by this Agreement
or the termination date provided for in Section 9.02 below, neither Seller nor
any Shareholder will, directly or indirectly, solicit any inquiries or proposals
or enter into or continue any discussions, negotiations or agreements relating
to the sale or exchange of the capital stock of Seller, the merger of Seller
with, or the direct or indirect acquisition or disposition of a significant
amount of the Purchased Assets otherwise than in the ordinary course of the
business of Seller to or from, any person other than Buyer or its affiliates or
provide any assistance or any information to or otherwise cooperate with any
person in connection with any such inquiry, proposal or transaction.

            (i) Transition Arrangements for Seller. Following the Closing Date,
Sage and Buyer will make their personnel reasonably available to Seller during
normal business hours on a reasonable basis consistent with past practices, at
no cost to Seller, and will cooperate with Seller's reasonable requests to
provide information in order that Seller can prepare all tax returns due with
respect to 1998 and 1999. As soon as practicable but for not more than sixty
(60) days following the Closing Date, Sage and Buyer will make their personnel

respect to payroll, benefits and management information systems. Buyer will make
Edward Cavazos available to assist Seller with the prosecution and defense of
the JDA litigation described on Exhibit 5.01(e).

            (j) Announcements; Confidentiality. Except as otherwise required by
law, neither Seller, any Shareholder, Buyer nor Sage shall make any announcement
to the public of the transactions contemplated hereby other than jointly or as
otherwise agreed by them in writing. Buyer and Sage will keep confidential any
information not otherwise publicly available which is derived from access,
investigation or information furnished by Seller or Shareholders in connection
with this Agreement, including the negotiations conducted in connection
herewith, and if the transactions contemplated hereby are not consummated by
March 17, 1999 or this Agreement is terminated prior to such time, Buyer will
promptly return to Seller or Shareholders all such information, and copies and
extracts therefrom, and will not thereafter use such information for any
purpose. Buyer, Sage, Seller and Shareholders will keep confidential all drafts
and executed copies of this Agreement and the contents hereof, except to the
extent necessary to comply with any applicable law or regulation or any request
or order of any government agency or court of competent jurisdiction and except
as otherwise agreed pursuant to the first sentence of this paragraph.
Notwithstanding the foregoing provisions of this Section 8.01(j), Buyer, Sage,
Seller and Shareholders may disclose any such information to their respective
attorneys, accountants and investment advisors and to their respective employees
on a need to know basis.

            Section 8.02 Consents to Assignments; Permits. Anything in this
Agreement or the bills of sale notwithstanding, to the extent that any Assigned
Agreement to be sold, assigned, transferred or conveyed to Buyer, or any claim,
right or benefit arising thereunder or resulting therefrom (the "Interests"), is
not capable of being sold, assigned, transferred or conveyed without the
approval, consent or waiver of the other party thereto, or any third person
(including a government or governmental unit), or if such sale, assignment,
transfer or conveyance or attempted assignment, transfer or conveyance would
constitute a breach thereof or a violation of any law, decree, order, regulation
or other governmental edict, except as expressly otherwise provided in this
Section 8.02, this Agreement shall not constitute a sale, assignment, transfer
or conveyance thereof, or an attempted assignment, transfer or conveyance
thereof. After the Closing, until any Interest has been validly and effectively
assigned to Buyer, (i) prior to the date two years following the Closing Date,
Seller shall hold such Interest for the benefit of Buyer and Buyer shall be
entitled to receive all benefits under such Interest and shall be responsible
for the obligations under such Interest to the extent relating to the benefits
received, and (ii) any such Interest shall, notwithstanding the failure to
receive any approval, consent or waiver (but so long as the same shall not
constitute a violation of law), be deemed to be assigned, transferred or
conveyed to Buyer if (x) written notice of such assignment, transfer or
conveyance is given to the other party to such Interest on or before the Closing
Date and (y) the other party to such Interest does not, within three months
after the Closing, object to such assignment, transfer or conveyance or acts in
a manner inconsistent with such assignment, transfer or conveyance; provided
that, in any case, Buyer shall be subject to all liabilities and obligations
under such Assigned 


                                       31
<PAGE>   36

Agreement to the extent such liabilities or obligations would have been an
Assumed Liability had the applicable Agreement been transferred and assigned.
Seller will cooperate with Buyer and Sage to obtain any such approval, consent
or waiver not obtained prior to the Closing Date.

            Section 8.03 Survival of Representations, Warranties, Etc.

            (a) All covenants and agreements of the parties made in this
Agreement or provided herein shall survive the Closing Date without limit,
unless otherwise specifically provided herein. All representations and
warranties of the parties made in this Agreement or as provided herein shall
survive the Closing Date and for a period ending on December 31, 2000,
notwithstanding any investigation at any time made by or on behalf of the other
party; provided, however, that the representations and warranties relating to
any Tax and any environmental matter and the representations and warranties set
forth in the first sentence of Section 5.01(d)(iii) and the third sentence of
Section 5.01(q)(i) shall survive until six months after the applicable statute
of limitations (or any extension thereof) has expired (as the case may be, the
applicable "Survival Period"); and provided, further, that any representation or
warranty which is the subject of a specific claim or dispute asserted prior to
the expiration of the Survival Period shall survive with respect to such claim
or dispute until final resolution thereof. All claims for indemnity hereunder
shall be made in writing, and shall state with reasonable specificity the matter
for which indemnification is sought.

            (b) Shareholders' and Seller's Agreement to Indemnify. Seller and
Shareholders other than Michael August, jointly and severally, and Michael
August, severally, hereby agree to indemnify and hold Sage and Buyer and their
respective shareholders, officers and directors, harmless from and against any
and all claims, liabilities, losses, damages or injuries, together with costs
and expenses, including reasonable legal fees, arising out of or resulting from
(i) any incorrectness or incompleteness in the representations and warranties
made by Shareholders or Seller in this Agreement, (ii) any breach in any
material respect by any Shareholder or Seller, unless waived, of any covenant or
agreement of any Shareholder or Seller contained in or arising out of this
Agreement, (iii) the Business conducted by Seller, or otherwise in connection
with the Purchased Assets, prior to the Closing Date (except for the Assumed
Liabilities), (iv) any failure by Seller to comply with the bulk sales laws of
any jurisdiction and (v) any and all actions, suits, proceedings, claims,
demands, assessments and judgements incidental to the foregoing or the
enforcement of such indemnification. Notwithstanding the above provisions, the
Shareholders shall have no indemnity obligation with respect to Section 8.08(c).

            In addition to the foregoing provisions of this Section 8.03(b) and
without limiting the generality of such provisions, Seller and Shareholders,
other than Michael August, jointly and severally, and Michael August, severally,
agree to fully indemnify and hold harmless Sage and its affiliates and
shareholders, officers and directors of any of the foregoing against and in
respect of and, will reimburse Sage and its affiliates for: (a) any and all
liability whatsoever, and however imposed (including any claim asserted against
or deficiency assessed against or collected from or paid by Buyer, Sage or
Seller 


                                       32
<PAGE>   37

or any affiliates thereof), in respect of any Taxes of Seller (or any
predecessors of Seller) for any and all periods through the period ending on the
Closing Date, without regard to whether or not the existence of such liability
would constitute a breach of a representation or warranty made by Seller or
Shareholders hereunder and (b) any and all liabilities of Seller existing on, or
arising under or relating to activities or transactions of Seller other than the
Assumed Liabilities.

            (c) Agreement of Buyer and Sage to Indemnify. Buyer and Sage, hereby
agree, jointly and severally, to indemnify and hold Shareholders, Seller and
Seller's officers, directors and shareholders harmless from and against any and
all claims, liabilities, losses, damages or injuries, together with costs and
expenses, including reasonable legal fees, arising out of or resulting from (i)
any incorrectness or incompleteness in the representations and warranties made
by Buyer or Sage in this Agreement, (ii) any breach in any material respect by
Buyer or Sage, unless waived, of any covenant or agreement of Buyer or Sage
contained in or arising out of this Agreement, (iii) the activities or
transactions conducted by Buyer or Sage in connection with the Purchased Assets
on or after the Closing Date, and the Assumed Liabilities on or after the
Closing Date, (iv) any breach by Buyer of the Assignment Agreement, and (v) any
and all actions, suits, proceedings, claims, demands, assessments and judgments
incidental to the foregoing or the enforcement of such indemnification.

            (d) Claims. Each party shall retain its own counsel and defend
itself, subject to being reimbursed by the indemnifying party for reasonable
attorneys' fees and expenses pursuant to this Section 8.03. The indemnified
party agrees to give the indemnifying party written notice of any claim, demand,
action, suit, proceeding or discovery of fact upon which the indemnified party
intends to base a claim for indemnification ("Claim") under this Section 8.03.
The indemnifying party shall have the right to participate jointly with the
indemnified party in the indemnified party's defense of any Claim. With respect
to any issue involved in any such Claim, as to which the indemnifying party
shall have acknowledged in writing the obligation to indemnify the indemnified
party hereunder, the indemnifying party shall have the sole right to defend,
settle or otherwise dispose of such Claim, on such terms as the indemnifying
party, in its sole discretion, shall deem appropriate; provided that such terms
do not result in any unindemnified expense to the indemnified party. In
addition, the parties agree to cooperate in any defense or settlement and to
give each other full access to all information relevant thereto.

            (e) Remedies. (i) Claims by Buyer and Sage hereunder (including any
payment required by Section 8.03(b)) shall be satisfied first, from the Escrow
Deposit (to the extent not theretofore released to Seller or Shareholders) and
second, by means of an offset against any payment due pursuant to Section
3.01(b) and then by claims against the Seller and Shareholders. The indemnity
provided under Section 8.03(b) of this Agreement shall be the sole and exclusive
remedy of the parties to this Agreement for any claim arising under this
Agreement, except with respect to fraud by the Shareholders, and each party
agrees that it will not pursue any other remedy. Seller and each Shareholder
acknowledge that irreparable damage would result if the provisions of Sections
8.01(b), (d) and (h) were not complied with in accordance with their 


                                       33
<PAGE>   38

respective specific terms. Accordingly, Seller and Shareholders agree that Buyer
and Sage shall have the right, in addition to any other rights or remedies it
may have, to injunctive relief, in respect of any failure on the part of Seller
or Shareholders to comply with provisions of Sections 8.01(b), (d) or (h).

            (ii) Minimum Claim. Notwithstanding anything to the contrary
contained herein, no Claim by Buyer or Sage, on the one hand, or by Seller and
Shareholders, on the other hand, may be made hereunder unless the aggregate
amount of Claims by such party or parties hereunder exceeds $150,000 and the
amount for which an indemnitee is entitled to indemnification shall be the
amount by which the claim exceeds $150,000; provided, however that Buyer and
Sage shall indemnify Mathew Wolf for the full amount of any Claim with respect
to the matters for which indemnity is provided under Section 8.06 and Seller
shall indemnify Sage and Buyer for the full amount of any Claim with respect to
the matters for which indemnity is provided under Section 8.08(c).

            (iii) Limitation of Indemnity Obligations. The respective
obligations of Seller and Shareholders under Section 8.03(b) and Buyer and Sage
under Section 8.03(c) shall be limited to an aggregate amount equal to the sum
of (w) the Cash Consideration, (x) the Fair Market Value (determined in
accordance with Section 8.03(e)(iv)) of the Purchase Price Shares, (y) the
liability under the Wolf Notes assumed by the Buyer pursuant to Section
2.02(a)(ii) and (z) the Fair Market Value of the Sage Options (or the number of
shares of Common Stock issued on exercise of such Sage Options) (determined in
accordance with Section 8.03(e)(iv)) (the sum of (w), (x), (y) and (z) is
collectively, the "Indemnity Limit"). Buyer and Sage agree that Shareholders'
obligation to pay any Claim for indemnity under this Section 8.03 shall be
limited to 80% of the amount of such Claim. The Seller's and Shareholder's
liability under this Section 8.03 shall be limited to returning the Purchase
Price Shares and cash equal to the amount of payments made by Sage or Buyer
under the Wolf Notes. This limitation shall also apply to any claim based on the
fraud of any Shareholder. The Seller and any Shareholder may satisfy any Claim
hereunder in cash or by the delivery of Common Stock to Sage. The Seller and any
Shareholder may satisfy a specified dollar amount of an indemnity obligation by
returning shares of Common Stock equal to such amount with such shares valued at
Fair Market Value on the date of satisfaction of such indemnity obligation. If
Seller or Shareholder makes a cash payment to satisfy an indemnity obligation,
then for purposes of determining when all of the Purchase Price Shares have been
returned, the Seller or Shareholder shall be deemed to have returned shares
equal to the amount of cash paid divided by the Fair Market Value of the shares
on the date of satisfaction of such indemnity obligation.

            (iv) Determination of Indemnity Limit. For purposes of determining
the Indemnity Limit:

                  (A) The Purchase Price Shares constituting the Share
Consideration shall have a Fair Market Value of $6.67 per share.

                  (B) The Purchase Price Shares which are delivered pursuant to
Section 3.01(b) shall have a Fair Market Value equal to the lesser of $6.67 per
share or 


                                       34
<PAGE>   39

the Fair Market Value per share on the date of the delivery of such shares to
the Shareholders pursuant to the Agreement to Deliver Shares.

                  (C) The Fair Market Value of the Sage Options shall be equal
to the Fair Market Value of the Common Stock subject to such Sage Options as
determined under clauses (A) and (B) minus the exercise price thereof.

            Section 8.04 Inspection of Records. Seller and Shareholders agree,
prior to the Closing Date and for the three year period following the Closing
Date, to allow representatives of the Buyer and Sage reasonable opportunity from
time to time during normal business hours to inspect and make copies of the
books of account and other records of Seller which pertain to the Business and
which are not transferred to Buyer hereunder. Seller and Shareholders further
agree, prior to the Closing Date and for the three year period following the
Closing Date, to cooperate with Sage's accountants, counsel and other agents and
representatives, and to provide access to the Seller's records and to use
reasonable commercial efforts to provide access to the records of the Seller's
independent auditors (including, without limitation, all financial and
accounting books, workpapers and any consolidating and other worksheets of its
independent auditors). Sage shall be solely responsible for the costs and
expenses associated therewith.

            Section 8.05 Employee Matters. Buyer shall offer employment to all
Employees at the same salaries or wages as in effect immediately prior to the
Closing Date other than those employees identified on Exhibit 8.05. Any such
Employees accepting such offer shall become employees of Buyer (the "Hired
Employees") on the Closing Date (the "Hire Date"). Each Hired Employee shall
receive (i) credit under Buyer's employee benefit plans (including, without
limitation, pension, welfare and fringe benefit plans) for purposes of
determining eligibility and vesting under such plans and (ii) credit for
purposes of determining vacation and severance pay, for the period during which
such Hired Employee was employed by the Seller; provided, however, that in no
event shall the Buyer be required to provide such a credit to a Hired Employee
to the extent that such credit would result in a duplication of benefits. Each
Hired Employee shall be entitled to participate in the employee benefit plans
maintained by Buyer without any waiting periods, any evidence of insurability or
the application of any preexisting condition restrictions (to the extent such
waiting periods, insurability or preexisting conditions were waived under
Seller's plan) and with credit for claims incurred prior to the Hire Date for
purposes of applying co-payments, deductibles, out of pocket maximums and
similar matters.

            Section 8.06 Release of Guaranties. Promptly following the Closing
Date, Sage will cause Mathew Wolf to be released from his obligations under the
First USA Merchant Services, Inc. Credit Card Processing Services Agreement
Guaranty Addendum dated April 15, 1997 and the Guaranty dated July 31, 1996 of
Mathew Wolf in respect of the Master Lease Agreement between Wolf Communications
Company and NEC America, Inc. Sage will indemnify and hold Mathew Wolf harmless
with respect to his obligations under such Guaranty Addendum and Guaranty with
respect to periods following the Closing Date.

            Section 8.07 Tax Reporting. With respect to the reporting of the
transactions contemplated by this Agreement for tax purposes, the parties agree
to the following:

            (a) The Common Stock shall not be valued at an amount greater than
$6.67 per share except that if Sage is required by any governmental or
regulatory authority including the Securities Exchange Commission ("SEC") to
value the Common Stock issued under this Agreement at a higher amount, Sage
shall be permitted to value the Common Stock at such higher amount. On a timely
basis, Sage shall keep Seller informed as to all developments with respect to
the reporting of the value recorded for the Common Stock issued hereunder and
shall immediately inform Seller at the final determination regarding such value.

            (b) The consideration paid to Seller (including the Common Stock)
shall be allocated among the assets set forth on the Company's balance sheet at
the Closing Date at the net book value thereof and the balance will be allocated
to "Section 197 Intangibles" as such term is defined in Section 197(c) of the
Code.

            (c) The parties will attempt to agree on the reporting of the
transaction on Internal Revenue Service Form 8594, but each party is free to
report the transaction as it shall determine, in its sole discretion, provided
such reporting must be consistent with this Section 8.07.

            (d) The receipt of additional shares of Common Stock under Section
3.01(b) is not intended to produce additional gain for Seller or to result in
additional basis for Buyer.

            Section 8.08 Sage Options. (a) Seller will cooperate with Buyer to
cause all options to purchase capital stock of Seller (the "Seller Options")
outstanding, whether or not exercisable, at the Closing Date under the Wolf
Communications Company 1995 Employee Stock Option Plan, as amended and the
Interliant, Inc. Lidestri Stock Option Plan and Agreement (together the "Seller
Plan"), to be converted into options to purchase Sage's Common Stock pursuant to
the terms of the Sage Networks, Inc. 1998 Stock Option Plan (the "Sage Plan") in
such manner that Sage is "assuming a stock option in a transaction to which
Section 424(a) applied". Each Seller Option converted by Sage ("Sage Options")
shall be exercisable upon the terms and conditions set forth in Exhibit A-5 and
shall be exercisable for that whole number of shares of Sage Common Stock
(rounded down to the nearest whole share) equal to the number of shares of
Seller's common stock, $.01 par value per share, subject to such Seller Option
immediately prior to the Closing Date multiplied by .6079167 and (B) the option
price per share of Sage common stock, $.01 par value per share, subject to a
Sage Option shall be an amount equal to the option price per share of Seller's
common stock, $.01 par value per share, subject to such Seller Option in effect
immediately prior to the Closing Date divided by .3988448 (the option price per
share, as so determined, being rounded up to the next full cent).


                                       36
<PAGE>   41

            (b) The holders of Seller Options shall have 30 days following the
Closing Date in which to execute a Stock Option Substitution Agreement and a
Sage Option Agreement in the forms to be provided to such holders. In the event
that a holder of a Seller Option (a) fails to execute both a Stock Option
Substitution Agreement and a Sage Option Agreement within such 30 day period and
(b) exercises the Seller Option prior to the expiration of such 30 day period (a
"Nonparticipating Option Holder"), then, and only in such event, Sage shall
deliver to Seller (or Seller's designee), within 5 business days following the
execution and delivery to Sage of a Subscription Agreement and the Shareholders
Agreement by the Seller or Seller's designee, a number of shares of Sage Common
Stock (the "Unconverted Option Shares") equal to the number of shares of Sage
Common Stock with respect to which such Nonparticipating Option Holder would
have been granted vested Sage Options had such Nonparticipating Option Holder
executed both a Stock Option Substitution Agreement and a Sage Option Agreement
within such 30 day period.

            (c) Seller agrees to hold Buyer and Sage harmless with respect to
any loss or damage suffered by either of them arising out of any claim of the
Nonparticipating Option Holder with respect to the failure of Seller to make
such shares of Sage Common Stock or equivalent value available to him or her.

            (d) Seller agrees that Exhibit 8.08 sets forth a list of the holders
of each Seller Option and the number of Seller Options held by each such holder
and that each nonqualified option is preceded by the letters "NQ" and each
incentive stock option is not preceded by any letters.

            Section 8.09 Escrow Deposit.

            (a) Promptly following the Closing Date, a portion of the Share
Consideration shall be deposited in accordance with the provisions of Section
3(a) of the Agreement to Deliver Shares (the "Escrow Deposit").

            (b) During the period from the date hereof through and including
March 31, 2000 (the "Termination Date"), Buyer may notify Mathew Wolf ("Wolf")
that Buyer is asserting a Claim pursuant to the indemnification provisions
contained in Section 8.03 hereof to all or any portion of the Escrow Deposit
("Claim Notice"). If Wolf has received a Claim Notice prior to the Termination
Date, and the Claim Notice states a claim of Buyer or Sage to all or a portion
of the Escrow Deposit (the "Claimed Amount"), Wolf and Buyer shall either:

                  (i) agree on the disposition of the entire Claimed Amount
(which may include a cash payment rather than the application of the Escrow
Deposit) or a portion of the Claimed Amount such agreement not to be
unreasonably withheld or delayed by Buyer or Seller; or

                  (ii) In the absence of such agreement, seek a final
unappealable order, judgment or decree from a court of competent jurisdiction
directing the delivery of all or a portion of the Claimed Amount.

<PAGE>   42

            (c) If on or before the Termination Date Wolf has not received a
Claim Notice or any Claim Notice has been resolved to the parties' satisfaction,
then promptly after the Termination Date, Wolf and Buyer shall release the
Escrow Deposit then being held hereunder to Wolf.

Stock owned by such Stockholder or by any Affiliate of such Stockholder, either
in person or by proxy, at any annual or special meeting of stockholders of the

Investors agrees that it will not and will not permit any Affiliate to grant any
proxy or enter into or agree to be bound by any voting trust with respect to its
shares of Stock or to enter into any stockholder agreements or arrangements of

                                  ARTICLE III

                   RESTRICTIONS ON TRANSFERS BY THE INVESTORS

                  3.01 Restrictions on Transfers Generally. Each Investor hereby
agrees that such Investor shall not, and shall not permit any Affiliate to,
directly or indirectly, transfer, sell or otherwise dispose of, or create, incur
or assume any Encumbrance with respect to any shares of Stock or Equity
Securities other than (i) pursuant to an effective registration statement under
the Securities Act or (ii) pursuant to an exemption from registration under the
Securities Act and any state securities or Blue Sky laws.

                  3.02 Tag Along Right. If WHO proposes to transfer shares of
Stock or Equity Securities to any Person or Persons (other than to an
Affiliate), WHO shall notify the Purchasers in writing (the "Tag Along Notice")
of such proposed transfer and its terms and conditions. Within fifteen (15) days
of receipt of a Tag Along Notice, each Purchaser shall notify WHO if it elects
to participate in such transfer ("Tag Along Right") and shall state the number
of shares of Stock or Equity Securities that the Purchaser desires to sell. Upon
electing to transfer, each Purchaser shall be obligated to sell, at the same
price and on the same terms as WHO, the number of shares stated in its notice to
WHO. Each Purchaser may elect to sell such number of shares of Stock and number
of Equity Securities as is equal to the number of shares of Stock and number of
Equity Securities to be transferred multiplied by a fraction, the numerator of
which shall be the aggregate number of shares of Stock and Equity Securities
held by such Purchaser (calculated on a fully diluted basis) and the denominator
of which shall be the aggregate number of shares of Stock and number of Equity
Securities held by all transferors (calculated on a fully diluted basis). Each
such Purchaser shall agree to enter into a purchase agreement in form and
substance approved by WHO to the extent such agreement shall contain customary
representations as to ownership of the shares to be purchased and the absence of
liens thereon. If the sale is not consummated within one hundred eighty (180)
days following the delivery of the Tag Along Notice, then each Purchaser shall
no longer be obligated to sell such Purchaser's shares of Stock and Equity
Securities pursuant to such Tag Along Right but shall remain subject to the
provisions of this Section 3.02 with respect to any subsequent proposed transfer
described

                                       5
<PAGE>   6
in this Section 3.02. In the event that the proposed transferee does not
purchase all the shares of Stock and number of Equity Securities that the
Purchaser elects to sell pursuant to the foregoing on the same terms and
conditions as the securities purchased from WHO, then WHO shall not be permitted
to sell any securities to the proposed transferee. If no Tag Along Notice is
received by the end of the 15 days referred to above, WHO shall have the right
for a 180 day period thereafter to transfer the securities to the proposed
transferee on terms and conditions no more favorable to WHO than those stated in
the Tag Along Notice and in accordance with the provisions of this Section 3.02.

                  3.03 Drag Along Right.

                  (a) If at any time the Company or WHO (the "Proposing
Investor") proposes to transfer in a bona fide arm's length sale all or
substantially all of the assets or shares of capital stock of the Company or the
Stock and Equity Securities owned by WHO to any Person or Persons who are not
Affiliates of the Proposing Investor (the "Proposed Transferee"), the Proposing
Investor shall have the right (the "Drag Along Right"), subject to applicable
law and compliance with any other restrictions applicable to such transfer, to
require all Investors to sell, pursuant to Section 3.03(b), to the Proposed
Transferee, on the same terms and conditions as applicable to the Proposing
Investors except as limited in Section 3.03(b), all (but not less than all) of
the shares of such Stock and Equity Securities then held by such Investors.

                  (b) To exercise a Drag Along Right, the Proposing Investor
shall give each Investor (each, a "Drag-Along Investor"), at least fifteen (15)
days prior to the proposed transfer to the Proposed Transferee, a written notice
(the "Drag Along Notice") containing (a) the name and address of the Proposed
Transferee and (b) the proposed purchase price and the terms of payment and
other material terms and conditions of the Proposed Transferee's offer. Each
Drag-Along Investor shall thereafter be obligated to sell all of its shares of
Stock and Equity Securities to the Proposed Transferee. Each such Drag Along
Investor shall agree to enter into a purchase agreement in form and substance
approved by the Proposing Investors to the extent such agreement shall contain
customary representations from each Drag Along Investor as to ownership of the
shares to be purchased and the absence of liens thereon and customary
indemnification provisions solely with respect to such representations from the
Drag Along Investor. If the sale is not consummated within a period of one
hundred eighty (180) days following the date of the Drag Along Notice, then each
Drag Along Investor shall no longer be obligated to sell such Investor's shares
of Stock and Equity Securities pursuant to such Drag Along Right but shall
remain subject to the provisions of this Section 3.03 with respect to any
subsequent proposed transfer described in this Section 3.03. The Drag-Along
Investor shall not be required to participate in a proposed transfer pursuant to
the exercise of a Drag Along Right unless its liability for breaches of
representations and warranties made in connection with the sale thereunder is
limited to no more than the total sale price received by such Drag-Along
Investor in such sale.

                  3.04 Transfers to Affiliates; Other Transfers. The Purchasers
agree not to transfer or otherwise dispose of any shares of Preferred Stock or
Equity Securities of the Company or use any shares of Preferred Stock or Equity
Securities of the Company as collateral

                                       6
<PAGE>   7
for the purposes of securing any indebtedness for borrowed money or otherwise;
provided, however, a Purchaser (a) shall transfer its shares of Stock or Equity
Securities as required by Section 3.03, (b) may transfer its shares of Stock and
Equity Securities (i) in accordance with Section 3.02, (ii) to an Affiliate of
such Purchaser that is an investment fund or similar entity and that, in the
reasonable judgement of the Company, is not a competitor of the Company, (iii)
by gift or bequest or through inheritance to, or for the benefit of, a spouse or
children or (iv) by will or the laws of descent and distribution (each
transferee referred to in (ii), (iii) or (iv), a "Permitted Transferee").

                  3.05 Transferees Subject to Agreement. In the event of any
transfer of shares of Stock or Equity Securities by the Stockholders pursuant to
this Agreement, the transferee shall hold such shares of Stock or Equity
Securities so acquired with all the rights conferred by, and subject to all of
the restrictions imposed by, this Agreement, except if such transferee acquires
such shares of Stock or Equity Securities pursuant to the Company's performance
of its obligation under Sections 4.01 and 4.02 hereof. Any transferee of any
shares of Stock or Equity Securities shall, as a condition of the consummation
of such transfer, agree to be subject to the terms of this Agreement.

                  3.06 Right of First Refusal.(a) If, at any time, any Purchaser
desires to sell, transfer or otherwise dispose of any shares of Stock or Equity
Securities than owned by such Purchaser (other than a transfer to a Permitted
Transferee or sales pursuant to an effective registration statement under the
Securities Act) to any third party pursuant to a bona fide offer, such selling
Purchaser (the "Seller") shall first give a written notice to the Company and
WHO (the "Seller's Notice") stating the Seller's desire to make such sale,
transfer or other disposition and the terms of the offer, including the identity
of the person making the offer (the "Bona Fide Purchaser"), the amount and kind
of securities proposed to be transferred and the purchase price offered to the
Seller by the Bona Fide Purchaser. The Seller's Notice shall constitute an
irrevocable offer by the Seller to sell to WHO or its Members (the "Eligible
Investors") and the Company such securities at the price and on the terms
offered by the Bona Fide Purchaser.

                  (i) Within 10 business days after the receipt by WHO and the
         Company of the Seller's Notice, the Company may elect to purchase such
         securities at the price and on the terms offered by the Bona Fide
         Purchaser in cash under this Section 3.06(a) by giving notice to the
         Seller, with copies to WHO and the Eligible Investors as to the number,
         if any, of such securities it is electing to purchase (the "Company
         Notice"). The election to purchase such securities shall be made on
         behalf of the Company by those members of the Board of Directors of the
         Company not affiliated or associated with the Seller. The Company
         Notice shall be deemed to be an irrevocable commitment to purchase from
         the Seller in cash at the price and on the terms offered by the Bona
         Fide Purchaser the number of such securities that the Company specifies
         in the Company Notice. If the Company elects to purchase any of such
         securities, the Company shall have 20 business days from the date the
         Company Notice has been sent to fund such purchase.

                  (ii) If the Company does not elect to purchase all of such
         securities, WHO may elect (within 5 business days after the receipt by
         WHO of the Company Notice) to

                                       7
<PAGE>   8
         purchase such securities at the price and on the terms offered by the
         Bona Fide Purchase in cash under this Section 3.06(a) by giving a
         notice to the Seller, with copies to the Company and the Eligible
         Investors, as to the number of such securities, if any, it is electing
         to purchase (the "WHO Notice"). The WHO Notice shall be deemed to be an
         irrevocable commitment to purchase from the Seller in cash at the price
         and on the terms offered by the Bona Fide Purchaser the number of such
         securities that WHO has elected to purchase pursuant to the WHO Notice.
         If WHO elects to purchase any of such securities, WHO shall have 20
         business days from the date the WHO Notice has been sent to fund such
         purchase.

                  (iii) If the Company and WHO do not elect to purchase all of
         such securities, any Eligible Investor may elect (within 5 business
         days after the date of receipt by the Eligible Investors of the WHO
         Notice) to purchase such securities at the price and on the terms
         offered by the Bona Fide Purchaser in cash under this Section 3.06(a)
         by giving a notice to the Seller, with a copy to the Company and WHO as
         to the number of such securities, if any, it is electing to purchase
         (the "Eligible Investor Notice"). Each Eligible Investor that is given
         an Eligible Investor Notice shall be allocated a portion of the
         remaining securities pro rata based on its ownership interest in WHO.
         The Eligible Investor Notice shall be deemed to be an irrevocable
         commitment to purchase from the Seller in cash at the price and on the
         terms offered by the Bona Fide Purchaser the number of such securities
         that the Company specified in the Eligible Investor Notice. If an
         Eligible Investor elects to purchase any of such securities, such
         Eligible Investor shall have 20 business days from the date the
         Eligible Investor Notice has been sent to fund such purchase.

                  (b) If the Company, WHO and the Eligible Investors fail to
elect to purchase such securities within the time periods specified in Section
3.06(a), then the Seller (i) shall be under no obligation to sell any of such
securities to WHO, the Company or any Eligible Investors, unless the Seller so
elects, and (ii) may, within a period of three months from the date of the
Seller's Notice, sell all (but not less than all) such securities to the Bona
Fide Purchaser in cash at a price per share not less than the price and on the
terms offered by the Bona Fide Investor; provided, however, that such Bona Fide
Purchaser shall, in accordance with the provisions of Section 3.05 hereof, agree

the same manner as the Seller of such shares.

                  3.07 Restrictive Legends. Each share of Stock and Equity

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended, and
                  neither the securities nor any interest therein may be
                  offered, sold, transferred, pledged or disposed of in the
                  absence of such registration or an exemption under such Act
                  and the rules and regulations thereunder. The securities

                                   ARTICLE IV

                               REGISTRATION RIGHTS

                  4.01 Piggyback Registration.

                  (a) If the Company proposes (including in connection with any
demand registration by a Stockholder) to file any registration statement under
the Securities Act with respect to any Stock or Equity Security (other than
pursuant to a registration statement on Form S-4 or S-8 or any successor or
similar forms in connection with an exchange offer or any offering of securities
solely to the Company's then existing stockholders or employees of the Company
and its subsidiaries and other than in connection with the Company's initial
public offering), the Company shall give written notice of such proposed filing
to each Stockholder at least 30 days prior to such proposed filing. Such notice
shall offer to each Stockholder the opportunity to include in such registration
statement for resale by the Stockholders, such number of shares of Common Stock
each may request in a written notice to the Company (which notice shall specify
the number of shares to be disposed of by such holder and the intended method of
disposition thereof) within 20 days after the receipt of such notice from the
Company (a "Piggyback Registration"). The Company shall permit, or shall cause
the managing underwriter of any such proposed offering to permit, the shares of
Stock or Equity Securities requested to be included in the registration to be
included on the same terms and conditions as are applicable to the other Stock
or Equity Securities included in such registration statement. The Company or
such subsidiary, as applicable, shall not be required to maintain the
effectiveness of the registration statement beyond the earlier to occur of (i)
180 days after the effective date of the registration statement; and (ii)
consummation of the distribution by the Stockholders whose shares of Stock or
Equity Securities are included in such registration statement. If a Stockholder
includes shares of Stock or Equity Securities in a Piggyback Registration with
respect to any registration of (i) shares by the Company or (ii) shares held by
one or more of the Company's other stockholders, such Piggyback Registration
shall not be deemed to be the exercise of a Demand Registration Right by such
Stockholder.

                  (b) If the managing underwriter or underwriters, if any,
advise the Stockholders seeking to register shares of Stock or Equity Securities
under this Section 4.01 in writing that in its or their opinion that, the number
of securities proposed to be sold in such registration (including securities to
be included pursuant to Section 4.01(a) above) will materially adversely affect
the success of such offering, the Company will include in such registration the
number of securities, if any, which in the opinion of such underwriter or
underwriters, or the Company or such subsidiary, as the case may be, can be sold
as follows: (i) first, the shares the Company

                                       9
<PAGE>   10
proposes to sell; (ii) second, the shares of Common Stock requested to be
included in such registration by WHO and the Purchasers; and (iii) third, the
securities requested to be included by each other Person exercising any
Piggyback Registration rights; provided that (a) if all shares requested to be
included in such Piggyback Registration by members of any group set forth above
are not to be included, selection of shares to be included from within such
groups shall be made pro rata based on the number of shares that each member of
such group holds and (b) no Stockholder shall have the right to register shares
pursuant to this Section 4.01 if the Company is at such time, and has been
continuously during the immediately preceding three years, subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act and such
Stockholder is then entitled to sell all of its shares of Stock or Equity
Securities without any volume restrictions pursuant to Rule 144 of the
Securities Act or all of such shares of Stock or Equity Securities may be sold
pursuant to Rule 144(k) of the Securities Act.

                  4.02 Demand Registration Rights. Upon the written request (the
"Request") of such Stockholder having such rights that the Company register
under the Securities Act any or all shares of Stock or Equity Securities then
held by such Stockholder, the Company will include such shares in a registration
statement on Form S-1, Form S-2 or Form S-3 (or any equivalent form), and use
its best efforts to register such shares, under the Securities Act (a "Demand
Registration Right"). A majority in interest of the Purchasers shall have two
Demand Registration Rights with respect to the registration of shares of Form
S-1 and twenty percent in interest of the Purchasers shall have two Demand
Registration Rights with respect to the registration of shares on Form S-3 at
any time after the Company becomes eligible to use Form S-3. A Demand
Registration Right may not be exercised unless the managing underwriter or
underwriters, if any, or the Purchasers exercising such Demand Registration
Rights, if the offering is not underwritten, advise the Company that the
anticipated aggregate offering price of the shares of Common Stock to be sold by
the Purchasers exercising such Demand Registration Rights is at least
$10,000,000. The Company will promptly give written notice of such requested
registration to all other Stockholders and thereupon will use its best efforts
to effect the registration under the Securities Act of (i) the shares of Stock
or Equity Securities, which the Company has been so requested to register, for
disposition in accordance with the intended method of disposition stated in such
request; and (ii) all other Common Stock, the holders of which shall have,
within 20 days after the receipt of such written notice from the Company, made
written request (which notice shall specify the intended method of disposition
thereof) to the Company for registration thereof, all to the extent required to
permit the disposition (in accordance with the intended method thereof as
aforesaid) by all such holders of securities so to be registered; provided,
however, that the Company shall not be obligated to effect any such registration
pursuant to this Section 4.02 at any time prior to the date six months following
the consummation of the Company's initial public offering. Notwithstanding the
foregoing, the Company may defer the effective date of such Demand Registration
Right for a period of up to 180 days from the date of its receipt of exercise of
the Demand Registration Right or such shorter period provided below, if (i) at
the time of the exercise of the Demand Registration Right, the Company is
engaged in a material transaction or has an undisclosed material corporate
development, which in either case, would be required to be disclosed under the
federal securities laws in the registration statement, and (ii) the Company's
Board of Directors has made a good faith determination that making such
disclosure at such time would materially adversely affect

                                       10
<PAGE>   11
such transaction or development (in which case, the Company shall disclose the
matter as promptly as practicable and promptly thereafter file the registration
statement). The Company may defer a Demand Registration Right for not more than
180 days in any one-year period. If the managing underwriter or underwriters, if
any, advise the Stockholders seeking to register shares of Common Stock, under
this Section 4.02 in writing that in its or their opinion the number of
securities proposed to be sold in such registration will materially adversely
affect the success of such offering, the Company will include in such
registration the number of securities, if any, which in the opinion of such
underwriter or underwriters can be sold on a pro rata basis based on the number
of shares that each Stockholder holds.

                  4.03 Holdback Agreement. Notwithstanding any other provision
in this Article 4, the Company and each Stockholder whose shares of Common Stock
are included in a registration statement agrees it will not, and the Company
shall use its best efforts to not permit any Affiliate to (and it shall be a
condition to the rights of each Stockholder under this Article 4 that such
Stockholder does not) offer for public sale any shares of Common Stock or Equity
Securities, or effect any sale of securities pursuant to Rule 144, during the 10
days prior to and the 180 days after the closing date of any underwritten
offering thereunder unless such shares are covered by such registration
statement or such shorter period is agreed to by any managing underwriter or
underwriters of such offering.

                  4.04 Expenses. All Registration Expenses, disbursements and
fees incurred by the Company and the Stockholders in connection with any
registration under this Article 4 shall be borne by the Company.

                  4.05 Registration Procedures. In connection with the
registration of shares of Stock or Equity Securities under the Securities Act
pursuant to this Agreement, the Company, will furnish each Stockholder whose
shares of Stock or Equity Securities re registered thereunder and each
underwriter, if any, with a copy of the registration statement (including all
exhibits thereto) and all amendments thereto and will supply each such
Stockholder and each underwriter, if any, with copies of any prospectus included
therein (including a preliminary prospectus and all amendments and supplements
thereto) in such quantities as may be reasonably necessary for the purposes of
the proposed sale or distribution covered by such registration.

                  Notwithstanding anything to the contrary herein, the only
securities which the Company shall be required to register pursuant to this
Article 4 shall be shares of Common Stock; provided, however, that in any
underwritten public offering, the holders of Preferred Stock and any securities
exercisable or exchangeable for or convertible into Common Stock, and any
rights, options or warrants to acquire any of the foregoing, shall be entitled
to sell such securities to the underwriters for exercise, exchange or conversion
and sale of the shares of Common Stock issued upon exercise, exchange or
conversion thereof.

                  In connection with the Company's registration obligations
pursuant to this Article 4, the Company will use its best efforts to effect such
registration to permit the sale of such shares of Stock or Equity Securities in
accordance with the intended method or methods of disposition thereof, and
pursuant thereto the Company will:

                                       11
<PAGE>   12
                  (a) prepare and file with the SEC, as soon as practicable
after receiving a written notice pursuant to Section 4.02, a registration
statement on any appropriate form under the Securities Act, which form shall be
selected by the Company (and shall be reasonably acceptable to any managing
underwriter chosen by holders of shares covered by such registration statement)
and shall be available for the sale of the shares in accordance with the
intended method or methods of distribution thereof, and use its reasonable
efforts to cause such registration statement to become effective; provided that
before filing a registration statement or any prospectus related thereto or any
amendments or supplements thereto, including documents incorporated by reference
after the initial filing of any registration statement, the Company will furnish
copies of all such documents proposed to be filed to the holders of the shares
covered by such registration statement and underwriters, if any, and make the
Company's representatives available for discussion of such documents and other
relevant matters and shall reasonably consider such changes in such documents
prior to the filing thereof as such holders or underwriters may timely and
reasonably request. If any Stockholder whose shares of Stock or Equity
Securities are covered by such registration statement shall reasonably object to
any disclosure in or omission from any registration statement or any amendment
thereto or any prospectus or any supplement thereto (including documents
incorporated by reference) which the Company in good faith on the advice of
counsel believes is necessary or appropriate to be included therein or omitted
therefrom, and prior to the effectiveness of such registration advises the
Company that it chooses not to participate in such offering, such Stockholder
may choose not to participate in such offering;

                  (b) prepare and file with the SEC such amendments and
post-effective amendments to the registration statement as may be necessary to
keep such registration statement effective for the required duration thereof;
cause the related prospectus to be supplemented by any required prospectus
supplement, and as so supplemented to be filed pursuant to Rule 424 under the
Securities Act; and comply with the relevant provisions of the Securities Act
during the applicable period in accordance with the intended methods of
disposition by the sellers thereof set forth in such registration statement or
supplement to such prospectus;

                  (c) notify the selling Stockholders and the managing
underwriters if any, promptly, and (if requested by any such holder) confirm
such advice in writing, (A) when a prospectus or any prospectus supplement or
post-effective amendment has been filed, and, with respect to a registration
statement or any post-effective amendment, when the same has become effective,
(B) of any request by the SEC for amendments or supplements to a registration
statement or related prospectus or for additional information, (C) of the
issuance by the SEC of any stop order suspending the effectiveness of a
registration statement or the initiation of any proceedings for that purpose,
(D) of the receipt by the Company of any written notification with respect to
the suspension of the qualification of any of the shares for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, and (E) of the existence of any fact known to the Company which results
in a registration statement, a prospectus or any document incorporated therein
by reference containing an untrue statement of a material fact or omitting to
state a material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading;

                                       12
<PAGE>   13
                  (d) use reasonable efforts to obtain the withdrawal of any
order suspending the effectiveness of a registration statement at the earliest
practicable moment;

                  (e) if reasonably requested by the managing underwriters or a
selling Stockholder, promptly incorporate in a prospectus supplement or
post-effective amendment such information as the managing underwriters or a
selling Stockholder agree should be included therein, subject to the last
sentence of Section 4.05(a); and promptly make all required filings of such
prospectus supplement or post-effective amendment as soon as notified of the
matters to be incorporated in such prospectus supplement or post-effective
amendment;

                  (f) prior to any public offering of Stock or Equity
Securities, register or qualify or cooperate with the selling Stockholders, the
managing underwriters, if any, and their respective counsel in connection with
the registration or qualification of such shares for offer and sale under the
securities or "blue sky" laws of such jurisdictions within the United States as
any seller or underwriter reasonably requests in writing and do any and all
other acts or things reasonably necessary or advisable to enable the disposition
in such jurisdictions of the shares of Common Stock covered by the applicable
registration statement; provided that the Company will not be required to
qualify generally to do business in any jurisdiction where it would not
otherwise be required to be so qualified or to take any action which would
subject itself to taxation (other than a nominal amount) in any such
jurisdiction or to general service of process in any jurisdiction where it is
not then so subject;

                  (g) cooperate with the selling Stockholders and the managing
underwriters, if any, to facilitate the timely preparation and delivery of
certificates representing shares of Common Stock to be sold and not bearing any
restrictive legends; and enable such shares to be in such denominations and
registered in such names as the managing underwriters may request at least two
business days prior to any sale of shares to the underwriters;

                  (h) use its best efforts to cause the shares covered by the
applicable registration statement to be listed or registered with or approved by
any stock exchange or quotation system on which the shares of Stock or Equity
Securities are then listed and by such governmental agencies or authorities
within the United States as may be reasonably necessary to enable the seller or
sellers thereof or the underwriters, if any, to consummate the disposition of
such shares;

                  (i) if any fact contemplated by Section 4.05 (c)(E) shall
exist, prepare a supplement or post-effective amendment to the applicable
registration statement or the related prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the shares of Stock or Equity Securities being
sold thereunder, such prospectus will not contain any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading;

                  (j) provide a CUSIP number for all shares of Stock or Equity
Securities, no later than the effective date of the applicable registration
statement;

                                       13
<PAGE>   14
                  (k) enter into such agreements (including an underwriting
agreement) and take all such other actions in connection therewith in order to
expedite or facilitate the disposition of such shares of Stock or Equity
Securities and in such connection, whether or not an underwriting agreement is
entered into and whether or not the registration is an underwritten
registration: (A) make such representations and warranties to the holders of
such shares and the underwriters, if any, in form, substance and scope as are
customarily made by issuers to underwriters in primary underwritten offerings;
(B) obtain opinions of counsel to the Company (including counsel which may be an
employee of the Company) and updates thereof which counsel and opinions (in
form, scope and substance) shall be reasonably satisfactory to the managing
underwriters, if any, covering the matters customarily covered in opinions
requested by such holders and underwriters; (C) obtain "cold comfort" letters
and updates thereof from the Company's independent certified public accountants,
addressed to the selling holders and the underwriters, if any, such letters to
be in customary form and covering matters of the type customarily covered in
"cold comforts" letters to underwriters in connection with primary underwritten
offerings; (D) if any underwriting agreement is entered into, the same shall set
forth in full the indemnification provisions and procedures of Section 4.06 with
respect to all parties to be indemnified pursuant to such Section 4.06; and (E)
the Company shall deliver such documents and certificates as may be reasonably
requested by the holders of the Stock or Equity Securities being sold and the
managing underwriters, if any, to evidence compliance with clause (A) hereof and
with any customary conditions contained in the underwriting agreement or other
agreement entered into by the Company. The above shall be done at each closing
under such underwriting or similar agreement or as and to the extent otherwise
reasonably required thereunder;

                  (l) make available for inspection during normal business hours
by a representative of each Stockholder, any underwriter participating in any
disposition pursuant to a registration statement and any attorney or accountants
retained by such selling Stockholders or underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors and employees to supply all information
reasonably requested by such representative, underwriter, attorney or accountant
in connection with such registration statement; provided, that such
Stockholders, underwriters, attorneys or accountants execute prior thereto an
agreement with the Company that all such records, information or document shall
be kept confidential by such persons unless (A) disclosure of such records,
information or documents is required by law or by court or administrative order,
or (B) such records, information or documents are or become (but only when they
become) generally available to the public other than as a result of disclosure
in violation of this paragraph; and

                  (m) otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make generally available to the
Stockholders earnings statements satisfying the provisions of Section 1 l(a) of

(or 90 days, if such period is a fiscal year) (A) commencing at the end of any
fiscal quarter in which shares of Stock or Equity Securities are sold to
underwriters in an underwritten offering, or (B) if not sold to underwriters in
such an offering beginning with the first month of the Company's first fiscal
quarter commencing after the effective date of the registration statement, which
statements shall cover such 12-month periods.

<PAGE>   15
                  The Company may require each Stockholder who is a party hereto
as to which any registration is being effected to furnish to the Company such
information and undertakings as it may reasonably request regarding such
Stockholder and the distribution of such securities as the Company may from time
to time reasonably request in writing.

                  Each Stockholder who is a party hereto agrees (i) that upon
receipt of any notice from the Company of the happening of any event of the kind
described in Section 4.05 (c)(E) such Stockholder will forthwith discontinue
such Stockholder's disposition of shares of Stock or Equity Securities pursuant
to the registration statement relating to such shares until such Stockholder's
receipt of the copies of the supplemented or amended prospectus contemplated by
Section 4.05(i) and, if so directed by the Company, will deliver to the Company
(at the Company's expense) all copies then in such Stockholder's possession of
the prospectus relating to such shares current at the time of receipt of such
notice and (ii) that such Stockholder will immediately notify the Company, at
any time when a prospectus relating to the registration of such shares is
required to be delivered under the Securities Act, of the happening of any event
as a result of which information previously furnished by such holder to the
Company in writing for inclusion in such prospectus contains an untrue statement
of a material fact or omits to state any material fact required to be stated
therein, or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

                  4.06 Indemnification and Contribution.

                  (a) Indemnification. (i) In the event of any registration
under the Securities Act of any shares of Stock pursuant to this Article 4, the
Company hereby agrees to indemnify and hold harmless each Stockholder offering
or selling such shares and any underwriter, and their respective officers,
directors, stockholders, members, partners and affiliates, in connection with
such offer or sale against such losses, claims, damages, liabilities, costs or
expenses (including reimbursement for reasonable legal and other expenses) to
which any such person may become subject under the Securities Act or otherwise
insofar as such losses, claims, damages, liabilities, costs or expenses arise
out of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such shares
were registered under the Securities Act, any preliminary prospectus, final
prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any application or other filing under any "blue sky" or
state securities law, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, provided that the Company shall not be liable in any such case to
the extent that any such loss, claim, damage, liability (or action or proceeding
in respect thereof), cost or expense arises out of or is based upon an untrue
statement or omission or alleged omission made in such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement, or application or other filing, in reliance upon and in conformity
with written information furnished to the Company through an instrument duly
executed by any holder of the Company's securities or underwriter.

                  (ii) In the event of any registration under the Securities Act
of any shares of Common Stock pursuant to this Article 4, each Stockholder whose
shares of Stock or Equity Securities are included in such registration hereby
agrees to indemnify and hold harmless, but only for an amount, with respect to
such Stockholder, not in excess of the net proceeds realized by such Stockholder
from the sale of its shares of Common Stock registered pursuant to such
registration statement, both the Company and its officers, directors,
stockholders and affiliates, and any underwriter, and their respective officers,
directors, stockholders and affiliates, in connection with such offer or sale
against such losses, claims, damages, liabilities, costs or expenses (including
reimbursement for reasonable legal and other expenses) to which any such person
may become subject under the Securities Act or otherwise insofar as such losses,
claims, damages, liabilities, costs or expenses arise out of or are based solely
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such shares were registered
under the Securities Act, any preliminary prospectus, final prospectus or
summary prospectus contained therein, or any amendment or supplement thereto, or
any application or other filing under any "blue sky" or state securities law, or
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, to the extent that
such untrue statement or omission or alleged omission made in such registration
statement, any such preliminary prospectus, final prospectus, summary

                                       16
<PAGE>   17
prospectus, amendment or supplement, or application or other filing, is
contained in any written information furnished to the Company through an
instrument duly executed by such holder.

                  (b) Contribution.(i) If the indemnification provided for in
Section 4.06(a) is unavailable to persons to be indemnified pursuant thereto in
respect of any losses, claims, damages, liabilities, costs or expenses referred
to therein, then the Company, in lieu of indemnifying such person, shall
contribute to the amount paid or payable by such person as a result of such
losses, claims, damages, liabilities, costs or expenses, in such proportion as
is appropriate to reflect the relative fault of the Company and such persons in
connection with the actions which resulted in such losses, claims, damages,
liabilities, costs or expenses, as well as any other relevant equitable
considerations. The relative fault of the Company and such persons shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, the Company or such persons, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such action. The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities, costs and expenses referred to above shall be
deemed to include any legal or other fees or expenses reasonably incurred by
such party in connection with any investigation or proceeding.

                  (ii) The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 4.06(b) were determined by
pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 4.06(b), an
indemnified person shall not be required to contribute any amounts in excess of
the amount by which the total price at which the shares of Stock or Equity
Securities were sold by such indemnified person and distributed to the public
exceeds the amount of any damages which such indemnified person has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission and provided, however, that such Stockholder's
aggregate liability shall be limited to the net proceeds realized by such
Stockholder in such offering. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                  (iii) If indemnification is available under this Section 4,
the Company shall indemnify each indemnified party to the full extent provided
herein without regard to the relative fault of the Company or the indemnified
party or any other equitable consideration provided for in this Section 4.06(b).

                  (iv) In the event that any provisions of an indemnification
clause in an underwriting agreement executed by or on behalf of a holder differs
from a provision in this Article IV, such provision in the underwriting
agreement shall determine such holder's rights in respect thereof.

                           RIGHT TO ACQUIRE SECURITIES

                  5.01 Right to Acquire Securities. If at any time the Company
proposes to issue in any non-public offering Stock or Equity Securities of the
Company (except for (i) issuances pursuant to the terms of any stock option or
other incentive plan duly approved by the Board of Directors or (ii) issuances
in connection with (w) a conversion or exchange of any outstanding securities,
(x) a stock dividend, (y) an acquisition pursuant to the Company's acquisition
strategy set forth in the Company's Confidential Offering Memorandum dated March
12, 1998, as amended through January 15, 1999, without regard to the aggregate
amount of such offering specified in such Confidential Offering Memorandum, (z)
a merger, reclassification or other reorganization, then, as to the Purchasers,
so long as they shall hold any shares of Preferred Stock or Common Stock, the
Company shall:

                  (a) give written notice setting forth in reasonable detail (i)
the designation and all of the terms and provisions of the equity securities
proposed to be issued (the "Proposed Securities"), including, where applicable,
the voting powers, preferences and relative participating, optional or other
special rights, and the qualification, limitations or restrictions thereof and
interest or dividend rate and maturity; (ii) the price and other terms of the
proposed sale of such securities; (iii) the amount of such securities proposed
to be issued; and (iv) such other information as may be reasonably required or
requested by any such Stockholder in order to evaluate the proposed issuance;
and

                  (b) each Purchaser shall have the option to acquire a number
of shares or, if applicable, share equivalents of the Proposed Securities equal
to the number of shares of the Proposed Securities multiplied by a fraction, the
numerator of which shall be the number of shares of Common Stock or Common Stock
Equivalents held by such Purchaser and the denominator of which shall be the
total number of shares of Common Stock outstanding on a fully diluted basis.

                  (c) Each such Purchaser that wishes to exercise its purchase
rights hereunder shall deliver a written notice to that effect to the Company
within fifteen (15) days after its receipt of the notice specified in Section
5.01(a) from the Company. To the extent that a sufficient number of shares of
Common Stock or Common Stock Equivalents are not available for such purpose, the
Company shall take all action necessary and proper to authorize and issue such
Common Stock or Common Stock Equivalents.

                  (d) Upon the expiration of the offering period described
above, the Company will be free to sell Proposed Securities that such Purchasers
have not elected to purchase during the ninety (90) days following such
expiration on terms and conditions (considered as a whole) no more favorable to
the buyers thereof than those offered to such Purchasers. Any Proposed
Securities offered or sold by the Company after such 90-day period must be
re-offered to such Purchasers pursuant to this Section 5.01. The election by any
such Purchaser not to exercise its

                                       18
<PAGE>   19
subscription rights under this Section 5.01 in any one instance shall not affect
its right (other than in respect of a reduction in its percentage holdings) as
to any subsequent proposed issuance. Any sale of such securities by the Company
without first giving such Purchasers the rights described in this Section 5.01
shall be void and of no force and effect, and the Company shall cause any
correction required to be effected.

                  5.02 Expiration of Right. The parties hereto agree that the
rights set forth in Article V hereof shall expire and be of no further force and
effect as of the Expiration Date.

                                   ARTICLE VI

                      CERTAIN REPRESENTATIONS AND COVENANTS

                  6.01 Stockholder Representation. Each Stockholder represents
and warrants as to itself that as of the Closing Date (after giving effect to
all transactions occurring on or as of the Closing Date) such Stockholder is not
a party with any other Person to any other agreement with respect to the
holding, voting, acquisition or disposition of shares of Stock or Equity
Securities except as previously disclosed to the other Stockholders.

                  6.02 Company Representation. The Company represents and
warrants that as of the Closing Date (after giving effect to all transactions
occurring on or as of the Closing Date) (i) it is not a party with any other
Person to any other agreement with respect to the holding, voting, acquisition
or disposition of shares of Stock or Equity Securities to the other
Stockholders, and (ii) it has not granted to any other Person any other
registration rights with respect to capital stock of the Company, and no holder
of any capital stock of the Company shall have as of the date hereof any right
to require registration of any capital stock of the Company under the Securities
Act or to include any security in any registration statement filed by the
Company under the Securities Act except pursuant hereto; provided, however, that
the Company is a party to the Registration Rights Agreement dated as of December
8, 1997, between the Company and WHO.

                                  MISCELLANEOUS

                  7.01 Injunctive Relief. It is acknowledged that it will be
impossible to measure in money the damages that would be suffered if the parties
fail to comply with certain of the obligations imposed on them by this
Agreement, including without limitation those obligations set forth in Article
II, Article III, Article IV and Article V and that in the event of any such
failure, an aggrieved Person will be irreparably damaged and will not have an
adequate remedy at law. Any such Person shall, therefore, be entitled to
injunctive relief and/or specific performance to enforce such obligations, and
if any action should be brought in equity to enforce any of such provisions of
this Agreement, none of the parties hereto shall raise the defense that there is
an adequate remedy at law.

                  7.02 Further Assurances. Each party hereto shall do and
perform or cause to be done and performed all such further acts and things and
shall execute and deliver all such other agreements, certificates, instruments
and documents as any other party hereto reasonably may request in order to carry
out the intent and accomplish the purposes of this Agreement and the
consummation of the transactions contemplated hereby.

                  7.03 Governing Law. This Agreement shall be construed and
enforced in accordance with, and the rights of the parties shall be governed by,
the laws of the State of New York.

                  7.04 Entire Agreement; Amendment; Waiver. This Agreement (i)
contains the entire agreement among the parties hereto with respect to the
subject matter hereof, (ii) supersedes all prior written agreements and
negotiations and oral understandings, if any, with respect thereto, (iii) may
not be amended or supplemented except by an instrument or counterparts thereof
in writing signed by the Company, WHO and a majority in interest of the
Purchasers then holding Stock or Equity Securities. No waiver of any term or
provision shall be effective unless in writing signed by the party to be charged
and such waiver shall not be effective to any other provision of this Agreement.

                  7.05 Binding Effect. This Agreement shall be binding on and
inure to the benefit of the parties hereto and, subject to the terms and
provisions hereof, their respective legal representatives, successors and
permitted assigns.

                  7.06 Invalidity of Provision. The invalidity or
unenforceability of any provision of this Agreement in any jurisdiction shall
not affect the validity or enforceability of the remainder of this Agreement in
that jurisdiction or the validity or enforceability of this Agreement, including
that provision, in any other jurisdiction.

                  7.07 Counterparts. This Agreement may be executed
simultaneously in two or more counterparts, all of which taken together shall be
deemed but one and the same instrument.

not require any notice, consent or waiver under any material indenture,

commission, board, bureau, agency or instrumentality, domestic or foreign, (ii)
arbitration proceeding relating to the Company or any subsidiary thereof pending

to any order, writ, injunction or decree served upon the Company or such
subsidiary of any court or of any Federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign. To the best of the Company's knowledge, (x) the Company and
each subsidiary thereof has complied in all material respects with all laws,
rules, regulations and orders applicable to its business, operations,
properties, assets, products and services and (y) there is no such law, rule,
regulation or order that would prohibit the Company or any subsidiary thereof
from conducting its business as conducted or as proposed to be conducted. The
Company and each subsidiary thereof has all necessary permits, licenses and
other authorizations required to conduct its business as conducted and as
proposed to be conducted, and the Company and each subsidiary thereof has been
operating its business pursuant to and in compliance with the terms of all such
permits, licenses and other authorizations, in any


                                        6
<PAGE>   10

such case, other than any failure with such terms which would not have a
Material Adverse Effect.

            Section 2.8. Patents, Trademarks, Etc. The Company owns or possesses
adequate licenses, assignments or other rights to use all patents, patent
applications, trademarks, trademark applications, service marks, service mark
applications, trade names, copyrights, software, source code, object code,
manufacturing processes, formulae, trade secrets, customer lists and know how,
including any third party rights connected therewith (collectively,
"Intellectual Property") necessary to the conduct of its business as conducted
and as proposed to be conducted, and no claim is pending against the Company or,
to the best of the Company's knowledge, threatened to the effect that the
operations of the Company infringe upon or conflict with the asserted rights of
any other person under any Intellectual Property. The Company has not licensed
on an exclusive basis any of its Intellectual Property.

            To the knowledge of the Company, no claim is pending against the
Company or threatened to the effect that any such Intellectual Property owned or
licensed by the Company, or which the Company otherwise has the right to use, is
invalid or unenforceable by the Company. There are no restrictions on the
ability of the Company to compete against any third party.

            The Company has taken reasonable measures to protect and preserve
the security, confidentiality and value of its Intellectual Property, including
its trade secrets and other confidential information. To the knowledge of the
Company, no employee or consultant of the Company has used any trade secrets or
other confidential information of any other person in the course of their work
for the Company. To the knowledge of the Company, the Company is not making
unlawful use of any confidential information or trade secrets of any past or
present employees of the Company.

            The Company does not have any agreements or arrangements with former
employers of any of its employees relating to confidential information or trade
secrets of such employers. To the knowledge of the Company, the activities of
the Company's employees on behalf of the Company do not violate any agreements
or arrangements known to the Company which any such employees have with former
employers or any other entity to whom such employees may have rendered
consulting services.

            Section 2.9. Leasehold Interests; Title to Property. (a) Neither the
Company nor any subsidiary thereof owns any real property. Each lease or
agreement to which the Company or any subsidiary thereof is a party under which
it is a lessee of any property, real or personal, which leases and agreements
are set forth on the attached Schedule II, is a valid and subsisting agreement.
No event has occurred and is continuing which, with due notice or lapse of time
or both, would constitute a default or event of default by the Company or any
subsidiary thereof under any such lease or agreement or, to the best of the
Company's knowledge, by any other party thereto. The Company has not received
any notice of termination under any such lease.


                                       7

            (b) The Company and its subsidiaries own their respective properties
and assets reflected on the Unaudited Financial Statements or acquired by them
since the date of the Unaudited Financial Statements (other than properties and
assets disposed of in the ordinary course of business since the date of the
Unaudited Financial Statements), and all such properties and assets are free and
clear of mortgages, pledges, security interests, liens, charges, claims,
restrictions and other encumbrances, except for (i) liens for or current taxes
not yet due and payable, (ii) liabilities reflected on the Unaudited Financial
Statements or set forth on the attached Schedule II and (iii) liabilities which

material respects) and has paid all taxes owed by it, except taxes which have
not yet accrued or otherwise become due or for which adequate provision has been
made in the Audited Financial Statements and Unaudited Financial Statements, as
appropriate. The provision for taxes on the Unaudited Financial Statements is
sufficient as of its date for the payment of all accrued and unpaid federal,
state, county and local taxes of any nature of the Company, and any applicable
taxes owing to any foreign jurisdiction, whether or not assessed or disputed.
All taxes and other assessments and levies which the Company is required to
withhold or collect have been withheld and collected and have been paid over to
the proper governmental authorities, except where the failure to pay would not
have a Material Adverse Effect. With regard to the income tax returns of the
Company, the Company has not received notice of any audit or of any proposed
deficiencies from any taxing authority, and no controversy with respect to taxes
of any type is pending or, to the knowledge of the Company, threatened. There
are in effect no waivers of applicable statutes of limitations with respect to
any taxes owed by the Company for any year.

            Section 2.12. Agreements. The Company believes that none of the
business agreements, instruments and documents to which the Company or any
subsidiary thereof is a party are individually material to the business of the
Company and its consolidated subsidiaries based on the revenues payable or
receivable thereunder, and all such agreements, instruments and documents are
valid, binding and in full force and effect. The Company is a party to several
agreements to provide connectivity which contain penalties if the agreements are
terminated by the Company prior to the end of the stated term thereof. The
Company and each subsidiary thereof, and to the best of the Company's knowledge,
each other party thereto, have in all material respects performed all the
obligations required to be performed by them to date (or each non-performing

By-laws, as amended.

            Section 2.13. Loans and Advances. Neither the Company nor any

to employees of the Company or a subsidiary thereof in respect to reimbursable
business expenses anticipated to be incurred by them in connection with their
performance of services for the Company or such subsidiary.

            Section 2.14. Assumptions, Guaranties, Etc. of Indebtedness of Other
Persons. Neither the Company nor any subsidiary thereof has assumed, guaranteed,
endorsed or otherwise become directly or contingently liable on any indebtedness
of any other person (including, without limitation, liability by way of

Federal, state or other governmental agency or instrumentality is or will be

the Preferred Shares and the Warrants.

            Section 2.16. Disclosure. To the best of the Company's knowledge and
the knowledge of each of its subsidiaries, neither this Agreement, nor any
Schedule or Exhibit to this Agreement, the Unaudited Financial Statements nor
any other document, certificate or written instrument furnished to the

Preferred Shares and the Warrants being purchased by it on the Closing Date is,
at its option, subject to the satisfaction, on or before the Closing Date, of
the following conditions:

            (a) Opinion of Company's Counsel. The Purchasers shall have received
from Dewey Ballantine LLP, special counsel for the Company or from the general
counsel of the Company, one or more opinions dated as of the Closing Date, in
form and scope satisfactory to the Purchasers and their counsel, to the effect
that:

            (i) The Company is a corporation duly incorporated, validly existing
and in good standing under the laws of its jurisdiction of incorporation. The
Company has the corporate power and authority to execute, deliver and perform
this Agreement and the Investors Agreement, to issue, sell and deliver the
Preferred Shares and the Warrants and, upon conversion or exercise thereof, to
issue and deliver the Conversion Shares. The Company has the corporate power and
authority to own its properties and to conduct its business as it is presently
being conducted.

            (ii) This Agreement and the Investors Agreement have been duly
authorized, executed and delivered by the Company and constitute the legal,
valid and binding obligations of the Company, enforceable in accordance with
their respective terms (subject, as to enforcement of remedies, to the
discretion of courts in awarding equitable relief and to applicable bankruptcy,
reorganization, insolvency, moratorium and similar laws affecting the rights of
creditors generally), except that such counsel need not express any opinion as
to the validity or enforceability of the indemnification and contribution
provisions of the Investors Agreement.

            (iii) The execution and delivery by the Company of this Agreement
and the Investors Agreement, the performance by the Company of its obligations
hereunder and thereunder, the issuance, sale and delivery of the Preferred
Shares and the Warrants and, upon conversion or exercise thereof, the issuance
and delivery of the Conversion Shares, will not (x) violate any provision of law
applicable to the Company, the Charter or By-laws, as amended, of the Company,
(y) to the knowledge of such counsel, violate any order of any court or other
agency of government specifically applicable to the Company or its property or
any agreement of the Company, or conflict with, result in a breach of or
constitute (with due notice or lapse of time or both) a material default under,
accelerate or terminate any such indenture, agreement or other instrument, or
result in the creation or imposition of any lien, charge, restriction, claim or
encumbrance of any nature whatsoever upon any of the properties or assets of the
Company.

            (iv) The authorized capital stock of the Company as of the date
hereof consists of (i) 2,647,658 shares of Series A Convertible Preferred Stock,
$.0l par value (the "Series A Preferred Stock") and (ii) 35,000,000 shares of
Common Stock.


                                       14
<PAGE>   18

Immediately prior to the Closing, 19,217,197 shares of Common Stock will be
validly issued and outstanding, fully paid and nonassessable with no personal
liability attaching to the ownership thereof and no shares of Series A Preferred
Stock will have been issued. The Series A Preferred Stock, when issued to the
Purchasers pursuant to the terms of this Agreement and for the consideration set
forth herein, will be validly issued and outstanding, fully paid and
nonassessable with no personal liability attaching to the ownership thereof.
Immediately prior to the Closing, based on a review by such counsel of the stock
record and minute books of the Company, the amount of Common Stock issuable
pursuant to warrants, options, convertible securities, and other rights
(contingent or other) to purchase or otherwise acquire equity securities of the
Company, and the number of shares of Common Stock and the number of such
subscriptions, warrants, options, convertible securities, and other such rights
held by each, will be as set forth in Schedule II and Schedule III.

            (v) Except as otherwise set forth on Schedule II of this Agreement,
to the best of such counsels' knowledge, there is no litigation or governmental
proceeding or investigation pending or threatened before any New York or United
States federal court or governmental agency or body against the Company or any
subsidiary thereof.

            (vi) The Preferred Shares, the Warrants and the Conversion Shares
have been duly authorized. The issuance, sale and delivery of the Preferred
Shares and the Warrants and the issuance and delivery of the Conversion Shares
upon conversion of the Preferred Shares and the exercise of the Warrants have
been duly authorized by all required corporate action; the Preferred Shares have
been validly issued, are fully paid and nonassessable with no personal liability
attaching to the ownership thereof; the Warrants have been validly issued and
the Conversion Shares have been duly reserved for issuance upon conversion of
the Preferred Shares and exercise of the Warrants and, when issued in accordance
with the terms of this Agreement and the Company's Charter, as amended, will be
validly issued, fully paid and nonassessable with no personal liability
attaching to the ownership thereof. Neither the issuance, sale or delivery of
the Preferred Shares nor the issuance or delivery of the Conversion Shares is
subject to any preemptive right of stockholders of the Company arising under law
or the Charter or By-laws of the Company, each as amended, or, to the knowledge
of such counsel, to any contractual right of first refusal or other right in
favor of any person, except as set forth on Schedule II. Except as otherwise set
forth on Schedule II of this Agreement, to the best of our knowledge, there are
no agreements to acquire shares of capital stock of the Company or commitments
on the part of the Company to issue securities or rights to securities of the
Company.

            (vii) Assuming the accuracy of the representations and warranties of
the Purchasers set forth in Article III, the offer and sale of the Preferred
Shares and the Warrants pursuant to the terms of this Agreement and the
Investors Agreement are exempt from the registration requirements of Section 5
of the Securities Act, as amended, and, under such securities laws as they
presently exist, the issuance of Conversion Shares

upon conversion of the Preferred Shares or exercise of the Warrants will also be
exempt from such registration and qualification requirements.

            (b) Representations and Warranties to be True and Correct. The
representations and warranties contained in Article II shall be true, complete
and correct on and as of the Closing Date with the same effect as though such
representations and warranties had been made on and as of such date, and an
authorized officer of the Company shall have certified to such effect to the
Purchasers in writing.

            (c) Performance. The Company shall have performed and complied in
all material respects with all agreements contained herein required to be
performed or complied with by it prior to or at the Closing Date, and an

writing to such effect and to the further effect that all of the conditions set
forth in this Article IV have been satisfied.

                          REGISTRATION RIGHTS AGREEMENT

            Registration Rights Agreement, dated as of December __, 1997,
between SAGE NETWORKS, INC., a Delaware corporation (the "Company") and WEB
HOSTING ORGANIZATION LLC (the "Investor").

                                   WITNESSETH

            WHEREAS, the Company and the Investor have entered into a
Subscription Agreement (the "Purchase Agreement"), dated as of the date hereof,
pursuant to which the Company issued and sold to the Investor, and the Investor
purchased from the Company, an aggregate of 1,000,000 shares of the Company's
Common Stock, par value $.01 per share (the "Common Stock"); and

            WHEREAS, in order to induce the Investor to enter into the Purchase
Agreement (and to purchase such shares of Common Stock) the Company has agreed
to provide certain registration rights with respect thereto;

            NOW, THEREFORE, in consideration of the foregoing, the mutual
covenants and agreements contained herein and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, it
is agreed as follows:

1. Definitions. The following terms shall have (unless otherwise provided
elsewhere in this Registration Rights Agreement) the following respective
meanings (such meanings being equally applicable to both the singular and plural
form of the terms defined):

            "Agreement" means this Registration rights Agreement, including all
amendments, modifications and supplements and any exhibits or schedules to any
of the foregoing, and shall refer to the Agreement as the same may be in effect
at the time such reference becomes operative.

            "Common Stock" has the meaning given to it in the recitals hereto.

            "Indemnified Party" has the meaning given to it in Section 6(c).

            "Indemnifying Party" has the meaning given to it in Section 6(c).

            "NASD" means the National Association of Securities Dealers, Inc.,
or any successor corporation thereto.
<PAGE>   4

            "Purchase Agreement" has the meaning given to it in the recitals
hereto.

            "Registering Security Holder" has the meaning given to it in Section
3.

            "Registrable Securities" means, collectively, (i) the shares of
Common Stock issued and sold to the Investor pursuant to the Purchase Agreement,
(ii) any shares of Common Stock hereafter acquired by the Investor, or (iii) any
shares of Common Stock hereafter distributed to the Investor by the Company as a
stock dividend, stock spit, recapitalization, reclassification or otherwise;
provided, however, that any such securities shall cease to be Registrable
Securities when (i) such securities shall have been registered under the
Securities Act, the registration statement with respect to the sale of such
securities shall have become effective under the Securities Act and such
securities shall have been disposed of pursuant to such effective registration
statement, (ii) such securities shall have been otherwise transferred, if new
certificates or other evidences of ownership for them not bearing a legend
restricting further transfer and not subject to any stop transfer order or other
restrictions on transfer shall have been delivered by the Company and subsequent
disposition of such securities shall not require registration or qualification
of such securities under the Securities Act or any state securities law then in
force, (iii) such securities shall cease to be outstanding or (iv) such
securities shall be eligible for sale pursuant to Rule 144(k) under the
Securities Act or any successor rule which permits resale of such securities
without restriction.

            2. Required Registration. From and after the earlier of December __,
1998 or 180 days after the closing of the Company's first underwritten public
offering of its capital stock, after receipt of a written request from the
Investor the Company shall, as expeditiously as is possible, use its best
efforts to effect the registration under the Securities Act of all shares of
Registrable Securities which the Company has been so requested to register;
provided, however, that, subject to the provisions of the immediately following
sentence, the Company shall not be required to effect more than three
registrations of Registrable Securities pursuant to this Section 2. In order to
count as an "effected" registration statement, such registration statement shall
not have been withdrawn and all Registrable Securities registered pursuant to it
(excluding any overallotment shares) shall have been sold. The Company shall
have the right to defer the filing of any registration statement requested
pursuant to this Section 2 for a period not to exceed ninety (90) days if in the
good faith determination of the Board of Directors of the Company the filing of
such registration statement would be seriously detrimental to the Company.


                                       2
<PAGE>   5

            3. Incidental Registration. If the Company at any time proposes to
file on its behalf and/or on behalf of any of its security holders (the
"Registering Security Holders") a Registration Statement under the Securities
Act on any form (other than a Registration Statement on Form S-4 or S-8 or any
successor form for securities to be offered in a transaction of the type
referred to in Rule 145 under the Securities Act or to employees of the Company
pursuant to any employee benefit plan, respectively) for the general
registration of securities to be sold for cash with respect to any class of
equity security (as defined in Section 3(a)(11) of the Securities Exchange Act)
of the Company, it will give written notice to the Investor at least 30 days
before the initial filing with the Commission of such Registration Statement,
which notice shall set forth the intended method of disposition of the
securities proposed to be registered by the Company. The notice shall offer to
include in such filing the aggregate number of shares of Registrable Securities
as the Investor may request.

            The Company shall thereupon include in such filing the number of
shares of Registrable Securities for which registration is so requested, subject
to the next sentence, and shall use its best efforts to effect registration
under the Securities Act of such shares. If the managing underwriter of a
proposed public offering shall advise the Company in writing that, in its
opinion, the distribution of the Registrable Securities requested to be included
in the registration concurrently with the securities being registered by the
Company or such Registering Security Holder would materially and adversely
affect the distribution of such securities by the Company or such Registering
Security Holder, then all Registering Security Holders shall reduce the amount
of securities each intended to distribute through such offering on a pro rata
basis. If, after excluding all securities desired to be offered by the
Registering Security Holders, the managing underwriter of the proposed public
offering shall advise the Company in writing that, in its opinion, the
distribution of the Registrable securities requested to be included in the
registration concurrently with the securities being registered by the Company
would materially and adversely affect the distribution of such securities, then
the Investor shall reduce the amount of Registrable Securities it intends to
distribute to the extent necessary to permit such distribution.

            4. Registration Procedures. If the Company is required by the
provisions of section 2 or 3 to use its best efforts to effect the registration
of any of its securities under the Securities Act, the Company will, as
expeditiously as possible:

                  (a) prepare and file with the Commission a Registration
Statement with respect to such securities and use its best efforts to cause such
Registration Statement to become and remain effective for a period of time
required for the dis-


                                       3
<PAGE>   6

position of such securities by the holders thereof, but not to exceed 180 days;

                  (b) prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities covered by such Registration Statement until
the earlier of such time as all of such securities have been disposed of in a
public offering or the expiration of 180 days;

                  (c) furnish to the Investor such number of copies of a summary
prospectus or other prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other
documents, as such selling security holders may reasonably request;

                  (d) use its best efforts to register or qualify the securities
covered by such Registration Statement under such other securities or blue sky
laws of such jurisdictions within the United States and Puerto Rico as each
holder of such securities shall request (provided, however, that the Company
shall not be obligated to qualify as a foreign corporation to do business under
the laws of any jurisdiction in which it is not then qualified or to file any
general consent to service of process), and do such other reasonable acts and
things as may be required of it to enable such holder to consummate the
disposition in such jurisdiction of the securities covered by such Registration
Statement;

                  (e) furnish, in connection with any registration of
Registrable Securities, on the date that such shares of Registrable Securities
are delivered to the underwriters for sale pursuant to such registration or, if
such Registrable Securities are not being sold through underwriters, on the date
that the Registration Statement with respect to such shares of Registrable
Securities becomes effective, (1) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and if such Registrable Securities are not being sold
through underwriters, then to the Investor, in customary form and covering
matters of the type customarily covered in such legal opinions; and (2) a
comfort letter dated such date, from the independent certified public
accountants of the Company, addressed to the underwriters, if any, and if such
Registrable Securities are not being sold through underwriters, then to the
Investor and, if such accountants refuse to deliver such letter to the Investor,
then to the Company in a customary form and covering matters of the type
customarily covered by such comfort letters and as the underwriters or such
holder(s) shall reasonably request;


                                       4
<PAGE>   7

                  (f) enter into customary agreements (including an underwriting
agreement in customary form with customary indemnification provisions) and take
such other actions as are reasonably required in order to expedite or facilitate
the disposition of such Registrable Securities; and

                  (g) otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission, and make available to its
security holders, as soon as reasonably practicable, but not later than 18
months after the effective date of the Registration Statement, an earnings
statement covering the period of at least 12 months beginning with the first
full month after the effective date of such Registration Statement, which
earnings statements shall satisfy the provisions of Section 11(a) of the
Securities Act.

            It shall be a condition precedent to the obligation of the Company
to take any action pursuant to this Agreement in respect of the securities which
are to be registered at the request of the Investor that (i) the Investor shall
furnish to the Company such information regarding the securities held by the
Investor and the intended method of disposition thereof as the Company shall
reasonably request and as shall be required under the Securities Act in
connection with the action taken by the Company and (ii) that the Investor shall
deliver and perform under such underwriting agreement as may be reasonably
requested by the underwriters.

            5. Expenses. All expenses incurred in complying with this Agreement,
including, without limitation, all registration and filing fees (including all
expenses incident to filing with the NASD), printing expenses, fees and
disbursements of counsel for the Company and counsel for the Investor, expenses
of any special audits incident to or required by any such registration and
expenses of complying with the securities or blue sky laws of any jurisdictions
pursuant to Section 4(d), shall be paid by the Company, except that the Company
shall not be liable for any fees, discounts or commissions to any underwriter in
respect of the securities sold by the Investor.

            6. Indemnification and Contribution. (a) In the event of any
registration of any Registrable Securities under the Securities Act pursuant to
this Agreement, the Company shall indemnify and hold harmless the Investor, its
directors and officers, and each other Person (including each underwriter) who
participated in the offering of such Registrable Securities and each other
Person, if any, who controls the Investor or such participating Person within
the meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, the Investor or any such director or officer or
participating Person or controlling Person may become subject under the
Securities Act, the Securities Exchange Act, state securities or blue sky laws
or any other statute or at common


                                       5
<PAGE>   8

law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon (i) any untrue or alleged untrue
statement of any material fact contained in any Registration Statement under
which such securities were registered under the Securities Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto, (ii) any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading or (iii) any violation or alleged violation by the Company of the
Securities Act, the Securities Exchange Act, state securities or blue sky laws,
any other statute or common law; and the company shall reimburse the Investor or
such director, officer or participating Person or controlling Person for any
legal or any other expenses reasonably incurred by the Investor or such
director, officer or participating Person or controlling Person in connection
with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the Company shall not be liable in any such case
to the extent that any such loss, claim, damage or liability arises out of or is
based upon any untrue statement or omission made in such Registration Statement,
preliminary prospectus, prospectus or amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by the
Investor specifically for use therein. Such indemnity shall remain in full force
and effect regardless of any investigation made by or on behalf of the Investor
or such director, officer or participating Person or controlling Person, and
shall survive the transfer of such securities by the Investor.

                  (b) In the event of any registration of any Registrable
Securities under the Securities Act pursuant to this Agreement, the Investor
shall indemnify and hold harmless the Company, its directors and officers, and
each other Person (including each underwriter) who participated in the offering
of such Registrable Securities and each other Person, if any, who controls the
company or such participating Person within the meaning of the Securities Act,
against any losses, claims, damages or liabilities, joint or several, to which
the Company or any such director or officer or participating Person or
controlling Person may become subject under the Securities Act, the Securities
Exchange Act, state securities or blue sky laws or any other statute or at
common law, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue or alleged untrue
statement of any material fact contained in any Registration Statement under
which such securities were registered under the Securities Act, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto, or arise out of or are based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case where such statement or
omission is in conformity with written information


                                       6
<PAGE>   9

provided by the Investor expressly for use therein, and shall reimburse the
Company or such director, officer or participating Person or controlling Person
for any legal or any other expenses reasonably incurred by the Company or such
director, officer or participating Person or controlling Person in connection
with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the Investor shall not be liable for any amounts
in excess of the net proceeds received by it for the sale of its shares. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Company or such director, officer or participating
Person or controlling Person, and shall survive the transfer of such securities
by the Investor.

                  (c) Each party entitled to indemnification under this Section
6 shall give notice to the party required to provide indemnification promptly
after such indemnified party has actual knowledge of any claim as to which
indemnity may be sought, and shall permit the indemnifying party to assume the
defense of any such claim or any litigation resulting therefrom; provided, that
counsel for the indemnifying party, who shall conduct the defense of such claim
or litigation, shall be approved by the indemnified party (whose approval shall
not be unreasonably withheld); and, provided, further, that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under this Section 6. The indemnified
party may participate in such defense at such party's expense; provided,
however, that the indemnifying party shall pay such expense if representation of
such indemnified party by the counsel retained by the indemnifying party would
be inappropriate due to actual or potential differing interests between the
indemnified party and any other party represented by such counsel in such
proceeding. No indemnifying party, in the defense of any such claim or
litigation shall, except with the consent of each indemnified party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect of such claim or
litigation, and no indemnified party shall consent to entry of any judgment or
settle such claim or litigation without the prior written consent of the
indemnifying party.

                  (d) If the indemnification provided for in this Section 6 is
unavailable to an indemnified party hereunder in respect of any losses, claims,
damages, liabilities or expenses referred to therein, then the indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative fault of the indemnifying party and indemnified parties in
connection with the actions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable


                                       7
<PAGE>   10

considerations; provided that in the case of the Investor, such contribution
shall not exceed any amounts in excess of the net proceeds received by the
Investor for the sale of its shares. The relative fault of such indemnifying
party and indemnified parties shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact, has been made by, or relates to information supplied by, such indemnifying
party or indemnified parties, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such action. The
amount paid or payable by a party as a result of the losses, claims, damages,
liabilities and expenses referred to above shall be deemed to include any legal
or other fees or expenses reasonably incurred by such party in connection with
any investigation or proceeding.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not also guilty of such fraudulent misrepresentation.

                  (e) The obligations of the Company and the Investor under this
Section 6 shall survive the completion of any offering of Registrable Shares in
a registration statement under Sections 2 and 3, and otherwise.

            7. Market Stand-Off Agreement. If requested by an underwriter of
securities of the Company the Investor shall not sell or otherwise transfer or
dispose of any securities held by it during the one hundred twenty (120) day
period following the effective date of a Registration Statement; provided, that
all officers and directors of the Company, as well as all beneficial owners of
greater than 10% of the Company's Common Stock, enter into similar agreements.

            8. Miscellaneous.

                  (a) No Inconsistent Agreements. This agreement supersedes all
prior agreements regarding registration rights between the Company and the
Investor and all such prior agreements are deemed terminated hereby. The Company
is a party to no other agreements regarding registration rights. The Company
will not hereafter enter into any agreement with respect to its securities which
is inconsistent with the rights granted to the holders of Registrable Securities
in this Agreement. It is understood and agreed that the Company shall not enter
into any agreement other than this Agreement pursuant to which any


                                       8
<PAGE>   11

holder of securities is given the right to require that the Investor's
securities be registered under the Securities Act. The Company may enter into
agreements other than this Agreement pursuant to which the holders of the
Company's securities are granted incidental registration rights; provided,
however, that any such agreement shall provide that, in the event that an
underwriter determines that the distribution of all securities requested to be
included in the registration would materially and adversely affect the
distributions of such securities by the Company or the Investor, the security
holders party to such other agreement shall reduce the number of their
securities proposed to be registered (to zero, if necessary), prior to the
Investor reducing the number of its securities proposed to be registered.

                  (b) Remedies. The Investor, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Agreement. The Company
agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Agreement and
hereby agrees to waive the defense in any action for specific performance that a
remedy at law would be adequate.

                  (c) Amendments and Waivers. Except as otherwise provided
herein, the provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to departure from the provisions hereof
may not be given unless the Company and the Investor has approved the same in
writing.

consolidation or reorganization; provided, however, that the provisions of this
Section 8(f) shall not apply in the event of any merger, consolidation or
reorganization in which the Company is not the surviving corporation if all
holders of then Registrable Shares are entitled to receive in exchange for such
Registrable Shares consideration consisting solely of (i) cash, (ii) securities
of the acquiring corporation which may be immediately sold to the public without
registration under the Securities Act, or (iii) securities of the acquiring
corporation which the acquiring corporation has agreed to register within 90

the Securities Act.

                  (g) Headings. The headings in this Agreement are for

meaning hereof.

                  (h) Governing Law. This Agreement shall be governed by and
construed in accordance with the internal laws of the State of Delaware (i.e.,
without regard to its conflicts of law rules).

                  (i) Severability. Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Agreement.

                                  ARTICLE III.

                  RESTRICTIONS ON TRANSFERS BY THE STOCKHOLDER

            Section 3.01 Restrictions on Transfers Generally. Each Stockholder
hereby agrees that such Stockholder shall not, and shall not permit any
Affiliate to, directly or indirectly, transfer, sell or otherwise dispose of, or
create, incur or assume any Encumbrance with respect to any shares of Stock or
Equity Securities other than (i) pursuant to an effective registration statement
under the Securities Act or (ii) pursuant to an exemption from registration
under the Securities Act and any state securities or Blue Sky laws.

            Section 3.02 Tag Along Right. If WHO proposes to transfer shares of
Stock or Equity Securities to any Person or Persons (other than to an Affiliate)
in a transaction, WHO shall notify the Wolf Holders in writing (the "Tag Along
Notice") of such proposed transfer and its terms and conditions. Within fifteen
(15) days of receipt of a Tag Along Notice, each Wolf Holder shall notify WHO if
it elects to participate in such transfer ("Tag Along Right") and shall state
the number of shares of Stock that such Wolf Holder desires to sell. Upon
electing to transfer, the Wolf Holders shall be obligated to sell, at the same
price and on the same terms as WHO, the number of shares stated in its notice to
WHO. The Wolf Holders may elect to sell such number of shares of Stock as is
equal to the aggregate number of shares of Stock and number of Equity Securities
to be transferred in such transaction multiplied by a fraction, the numerator of
which shall be the aggregate number of shares of Stock held by the Wolf Holders
(calculated on a fully diluted basis) and the denominator of which shall be the
aggregate number of shares of Stock and number of Equity Securities held by all
transferors (calculated on a fully diluted basis). The Wolf Holders shall agree
to enter into a purchase agreement in form and substance approved by WHO to the
extent such agreement shall contain customary representations as to ownership of
the shares to be purchased and the absence of liens thereon. If the sale is not
consummated within one hundred eighty (180) days following the delivery of the
Tag Along Notice, then a Wolf Holder shall no longer be obligated to sell its
shares of Stock pursuant to such Tag Along Right but shall remain subject to the
provisions of this Section 3.02 with respect to any subsequent proposed transfer
described in this Section 3.02. In the event that the proposed transferee does
not purchase all the shares of Stock that a Wolf Holder elects to sell pursuant
to the foregoing on the same terms and conditions as the securities purchased
from WHO, then WHO shall not be permitted to sell any securities to the proposed
transferee. If no Tag Along Notice is received by the end of the 15 days
referred to above, WHO shall have the right for a 180 day period thereafter to
transfer the securities to the proposed transferee on terms and conditions no
more favorable to WHO than those stated in the Tag Along Notice and in
accordance with the provisions of this Section 3.02.

            Section 3.03 Drag Along Right. (a) If at any time the Company or WHO
(the "Proposing Investor") proposes to transfer in a bona fide arm's-length sale
all or substantially all of the shares of capital stock of the Company or the
Stock and Equity Securities owned by WHO to any Person or Persons who are not
Affiliates of the Proposing Investor (the "Proposed Transferee"), the Proposing
Investor shall have the right (the "Drag Along Right"), subject to applicable
law and compliance with any other restrictions applicable to such transfer, to
require

all Interliant Holders to sell, pursuant to Section 3.03(b), to the Proposed
Transferee, on the same terms and conditions as applicable to the Proposing
Investors except as limited in Section 3.03(b), such number of shares of Stock
as is equal to the aggregate number of shares of Stock and number of Equity
Securities to be transferred in such transaction multiplied by a fraction, the
numerator of which shall be the aggregate number of shares of Stock held by the
Interliant Holders (calculated on a fully diluted basis) and the denominator of
which shall be the aggregate number of shares of Stock and number of Equity
Securities held by all transferors (calculated on a fully diluted basis).

            (b) To exercise a Drag Along Right, the Proposing Investor shall
give the Company and each Interliant Holder (each, a "Drag Along Investor"), at
least fifteen (15) days prior to the proposed transfer to the Proposed
Transferee, a written notice (the "Drag Along Notice") containing (a) the name
and address of the Proposed Transferee and (b) the proposed purchase price and
the terms of payment and other material terms and conditions of the Proposed
Transferee's offer. Each Drag Along Investor shall thereafter be obligated to
sell its shares of Stock to the Proposed Transferee (such number of shares of
Stock to be calculated in accordance with Section 3.03(a)). Each such Drag Along
Investor shall agree to enter into a purchase agreement in form and substance
approved by the Proposing Investor to the extent such agreement shall contain
customary representations from each Drag Along Investor as to ownership of the
shares to be purchased and the absence of liens thereon and customary
indemnification provisions solely with respect to such representations from the
Drag Along Investor. If the sale is not consummated within a period of one
hundred eighty (180) days following the date of the Drag Along Notice, then each
Drag Along Investor shall no longer be obligated to sell such Drag Along
Investor's shares of Stock pursuant to such Drag Along Right but shall remain
subject to the provisions of this Section 3.03 with respect to any subsequent
proposed transfer described in this Section 3.03. The Drag Along Investor shall
not be required to participate in a proposed transfer pursuant to the exercise
of a Drag Along Right unless its liability for breaches of representations and
warranties made in connection with the sale thereunder is limited to no more
than the total sale price received by such Drag Along Investor in such sale.

            Section 3.04 Permitted Transfers. The Interliant Holders agree not
to transfer or otherwise dispose of any Stock of the Company or use any Stock of
the Company as collateral for the purposes of securing any indebtedness for
borrowed money or otherwise; provided, however, the Interliant Holders (a) shall
transfer their shares of Stock as required by Section 3.03, (b) may transfer
their shares of Stock (i) in accordance with Section 3.02 or Section 3.06, (ii)
to another Wolf Holder or an Affiliate of an Interliant Holder that is an
investment fund or similar entity and that, in the reasonable judgment of the
Company, is not a competitor of the Company, (iii) by gift or bequest or through
inheritance to, or for the benefit of, a spouse or children, (iv) by will or the
laws of descent and distribution or (v) to generate proceeds used to pay taxes
incurred by the Wolf Holders in connection with the transactions contemplated by
the Purchase Agreement and the Agreement to Deliver Shares.

            Section 3.05 Transferees Subject to Agreement. In the event of any
transfer of shares of Stock by any Interliant Holder pursuant to this Agreement,
the transferee shall hold 


                                       7
<PAGE>   8

such shares of Stock so acquired with all the rights conferred by, and subject
to all of the restrictions imposed by, this Agreement applicable to the
transferor of such shares of Stock. Any transferee of any shares of Stock shall,
as a condition of the consummation of such transfer, agree to be subject to the
terms of this Agreement.

            Section 3.06 Right of FIrst Refusal. (a) If, at any time, any
Interliant Holder desires to sell, transfer or otherwise dispose of any shares
of Stock then owned by such Interliant Holder (other than transfers pursuant to
(i) an effective registration statement under the Securities Act, (ii) Section
3.02, (iii) Section 3.03 or (iv) Section 3.04 (b)(ii), (iii) and (iv)) to any
third party pursuant to a bona fide offer, such Interliant Holder (the "Seller")
shall first give a written notice to the Company and WHO (the "Seller's Notice")
stating the Seller's desire to make such sale, transfer or other disposition and
the terms of the offer, including the identity of the person making the offer
(the "Bona Fide Purchaser"), the amount and kind of securities proposed to be
transferred and the purchase price offered to the Seller by the Bona Fide
Purchaser. The Seller's Notice shall constitute an irrevocable offer by the
Seller to sell to WHO or its Members (the "Eligible Investors") and the Company
such securities at the price and on the terms offered by the Bona Fide
Purchaser.

      (i)   Within 10 business days after the receipt by WHO and the Company of
            the Seller's Notice, the Company may elect to purchase such
            securities at the price and on the terms offered by the Bona Fide
            Purchaser in cash under this Section 3.06(a) by giving notice to the
            Seller, with copies to WHO and the Eligible Investors as to the
            number, if any, of such securities it is electing to purchase (the
            "Company Notice"). The election to purchase such securities shall be
            made on behalf of the Company by those members of the Board of
            Directors of the Company not affiliated or associated with the
            Seller. The Company Notice shall be deemed to be an irrevocable
            commitment to purchase from the Seller in cash at the price and on
            the terms offered by the Bona Fide Purchaser the number of such
            securities that the Company specifies in the Company Notice. If the
            Company elects to purchase any of such securities, the Company shall
            have 20 business days from the date the Company Notice has been sent
            to fund such purchase.

      (ii)  If the Company does not elect to purchase all of such securities,
            WHO may elect (within 5 business days after the receipt by WHO of
            the Company Notice) to purchase such securities at the price and on
            the terms offered by the Bona Fide Purchase in cash under this
            Section 3.06(a) by giving a notice to the Seller, with copies to the
            Company and the Eligible Investors, as to the number of such
            securities, if any, it is electing to purchase (the "WHO Notice").
            The WHO Notice shall be deemed to be an irrevocable commitment to
            purchase from the Seller in cash at the price and on the terms
            offered by the Bona Fide Purchaser the number of such securities
            that WHO has elected to purchase pursuant to the WHO Notice. If WHO
            elects to purchase any of such securities, WHO shall have 20


                                       8
<PAGE>   9

            business days from the date the WHO Notice has been sent to fund
            such purchase.

      (iii) If the Company and WHO do not elect to purchase all of such
            securities, any Eligible Investor may elect (within 5 business days
            after the date of receipt by the Eligible Investors of the WHO
            Notice) to purchase such securities at the price and on the terms
            offered by the Bona Fide Purchaser in cash under this Section
            3.06(a) by giving a notice to the Seller, with a copy to the Company
            and WHO as to the number of such securities, if any, it is electing
            to purchase (the "Eligible Investor Notice"). Each Eligible Investor
            that is given an Eligible Investor Notice shall be allocated a
            portion of the remaining securities pro rata based on its ownership
            interest in WHO. The Eligible Investor Notice shall be deemed to be
            an irrevocable commitment to purchase from the Seller in cash at the
            price and on the terms offered by the Bona Fide Purchaser the number
            of such securities that the Company specified in the Eligible
            Investor Notice. If an Eligible Investor elects to purchase any of
            such securities, such Eligible Investor shall have 20 business days
            from the date the Eligible Investor Notice has been sent to fund
            such purchase.

            (b) If the Company, WHO and the Eligible Investors fail to elect to
purchase such securities within the time periods specified in Section 3.06(a),
then the Seller (i) shall be under no obligation to sell any of such securities
to WHO, the Company or any Eligible Investors, unless the Seller so elects, and
(ii) may, within a period of one hundred and eighty (180) days from the date of
the Seller's Notice, sell all (but not less than all) such securities to the
Bona Fide Purchaser in cash at a price per share not less than the price and on
the terms offered by the Bona Fide Investor; provided, however, that such Bona
Fide Purchaser shall, in accordance with the provisions of Section 3.05 hereof,
agree to execute and be bound by the terms of this Agreement to the same extent
and in the same manner as the Seller of such shares.

            Section 3.07 Restrictive Legends. Each share of Stock and Equity
Securities shall bear a legend in substantially the following form:

            The securities represented by this certificate have not been
            registered under the Securities Act of 1933, as amended, and neither
            the securities nor any interest therein may be offered, sold,
            transferred, pledged or disposed of in the absence of such
            registration or an exemption under such Act and the rules and
            regulations thereunder. The securities represented by this
            certificate are subject to, and are transferable only upon
            compliance with, the provisions of the Shareholders Agreement dated
            as of March 2, 1999 among Sage Networks, Inc. and certain of its
            shareholders. A copy of the above-referenced agreement is on file at
            the office of Sage Networks, Inc.

                                  ARTICLE IV.

                               REGISTRATION RIGHTS

            Section 4.01 Piggyback Registration. (a) If the Company proposes
(including in connection with any demand registration by a Stockholder) to file
any registration statement under the Securities Act with respect to any Stock or
Equity Security (other than pursuant to a registration statement on Form S-4 or
S-8 or any successor or similar forms in connection with an exchange offer or
any offering of securities solely to the Company's then existing stockholders or
employees of the Company and its subsidiaries and other than in connection with
the Company's initial public offering), the Company shall give written notice of
such proposed filing to the Wolf Holders at least 30 days prior to such proposed
filing. Such notice shall offer to the Wolf Holders the opportunity to include
in such registration statement for resale by the Stockholders, such number of
shares of Common Stock each may request in a written notice to the Company
(which notice shall specify the number of shares to be disposed of by such
holder and the intended method of disposition thereof) within 20 days after the
receipt of such notice from the Company (a "Piggyback Registration"). The
Company shall permit, or shall cause the managing underwriter of any such
proposed offering to permit, the shares of Stock or Equity Securities requested
to be included in the registration to be included on the same terms and
conditions as are applicable to the other Stock or Equity Securities included in
such registration statement. The Company or such subsidiary, as applicable,
shall not be required to maintain the effectiveness of the registration
statement beyond the earlier to occur of (i) 180 days after the effective date
of the registration statement; and (ii) consummation of the distribution by the
Wolf Holders of the shares of Stock or Equity Securities that are included in
such registration statement.

            (b) If the managing underwriter or underwriters, if any, advise the
Wolf Holders and in writing that in its or their opinion that, the number of
securities proposed to be sold in such registration (including securities to be
included pursuant to Section 4.01(a) above) will materially adversely affect the
success of such offering, the Company will include in such registration the
number of securities, if any, which in the opinion of such underwriter or
underwriters, or the Company or such subsidiary, as the case may be, can be sold
as follows: (i) first, the shares the Company proposes to sell; (ii) second, the
shares of Common Stock requested to be included in such registration by WHO, the
purchasers of the Preferred Stock and the Wolf Holders; and (iii) third, the
securities requested to be included by each other Person exercising any
Piggyback Registration rights; provided that (a) if all shares requested to be
included in such Piggyback Registration by members of any group set forth above
are not to be included, selection of shares to be included from within such
groups shall be made pro rata based on the number of shares that each member of
such group holds and (b) the Wolf Holders shall not have the right to register
shares pursuant to this Section 4.01 if the Company is at such time, and has
been continuously during the immediately preceding three years, subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act and such
Stockholder is then entitled to 


                                       10
<PAGE>   11

sell all of its shares of Stock or Equity Securities without any volume
restrictions pursuant to Rule 144 of the Securities Act or all of such shares of
Stock or Equity Securities may be sold pursuant to Rule 144(k) of the Securities
Act.

            Section 4.02 Holdback Agreement. Notwithstanding any other provision
in this Article 4, the Company and The Wolf Holders each agree that it will not,
and the Company shall use its best efforts to not permit any Affiliate to (and
it shall be a condition to the rights of each Stockholder under this Article 4
that such Stockholder does not) offer for public sale any shares of Common Stock
or Equity Securities, or effect any sale of securities pursuant to Rule 144,
during the 10 days prior to and the 180 days after the closing date of any
underwritten offering thereunder unless such shares are covered by such
registration statement or such shorter period is agreed to by any managing
underwriter or underwriters of such offering.

            Section 4.03 Expenses. All Registration Expenses, disbursements and
fees incurred by the Company and the Stockholders in connection with any
registration under this Article 4 shall be borne by the Company.

            Section 4.04 Registration Procedures. In connection with the
registration of shares of Stock or Equity Securities under the Securities Act
pursuant to this Agreement, the Company, will furnish each Stockholder whose
shares of Stock or Equity Securities are registered thereunder and each
underwriter, if any, with a copy of the registration statement (including all
exhibits thereto) and all amendments thereto and will supply each such
Stockholder and each underwriter, if any, with copies of any prospectus included
therein (including a preliminary prospectus and all amendments and supplements
thereto) in such quantities as may be reasonably necessary for the purposes of
the proposed sale or distribution covered by such registration.

            Notwithstanding anything to the contrary herein, the only securities
which the Company shall be required to register pursuant to this Article 4 shall
be shares of Common Stock; provided, however, that in any underwritten public
offering, the holders of Preferred Stock and any securities exercisable or
exchangeable for or convertible into Common Stock, and any rights, options or
warrants to acquire any of the foregoing, shall be entitled to sell such
securities to the underwriters for exercise, exchange or conversion and sale of
the shares of Common Stock issued upon exercise, exchange or conversion thereof.

            In connection with the Company's registration obligations pursuant
to this Article 4, the Company will use its best efforts to effect such
registration to permit the sale of such shares of Stock or Equity Securities in
accordance with the intended method or methods of disposition thereof, and
pursuant thereto the Company will:

            (a) prepare and file with the SEC, as soon as practicable after
receiving a written notice pursuant to Section 4.02, a registration statement on
any appropriate form under the Securities Act, which form shall be selected by
the Company (and shall be reasonably acceptable to any managing underwriter
chosen by holders of shares covered by such registration statement) and shall be
available for the sale of the shares in accordance with the intended 


                                       11
<PAGE>   12

method or methods of distribution thereof, and use its reasonable efforts to
cause such registration statement to become effective; provided that before
filing a registration statement or any prospectus related thereto or any
amendments or supplements thereto, including documents incorporated by reference
after the initial filing of any registration statement, the Company will furnish
copies of all such documents proposed to be filed to the holders of the shares
covered by such registration statement and underwriters, if any, and make the
Company's representatives available for discussion of such documents and other
relevant matters and shall reasonably consider such changes in such documents
prior to the filing thereof as such holders or underwriters may timely and
reasonably request. If any Stockholder whose shares of Stock or Equity
Securities are covered by such registration statement shall reasonably object to
any disclosure in or omission from any registration statement or any amendment
thereto or any prospectus or any supplement thereto (including documents
incorporated by reference) which the Company in good faith on the advice of
counsel believes is necessary or appropriate to be included therein or omitted
therefrom, and prior to the effectiveness of such registration advises the
Company that it chooses not to participate in such offering, such Stockholder
may choose not to participate in such offering;

            (b) prepare and file with the SEC such amendments and post-effective
amendments to the registration statement as may be necessary to keep such
registration statement effective for the required duration thereof; cause the
related prospectus to be supplemented by any required prospectus supplement, and
as so supplemented to be filed pursuant to Rule 424 under the Securities Act;
and comply with the relevant provisions of the Securities Act during the
applicable period in accordance with the intended methods of disposition by the
sellers thereof set forth in such registration statement or supplement to such
prospectus;

            (c) notify the selling Stockholders and the managing underwriters if
any, promptly, and (if requested by any such holder) confirm such advice in
writing, (A) when a prospectus or any prospectus supplement or post-effective
amendment has been filed, and, with respect to a registration statement or any
post-effective amendment, when the same has become effective, (B) of any request
by the SEC for amendments or supplements to a registration statement or related
prospectus or for additional information, (C) of the issuance by the SEC of any
stop order suspending the effectiveness of a registration statement or the
initiation of any proceedings for that purpose, (D) of the receipt by the
Company of any written notification with respect to the suspension of the
qualification of any of the shares for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose, and (E) of the
existence of any fact known to the Company which results in a registration
statement, a prospectus or any document incorporated therein by reference
containing an untrue statement of a material fact or omitting to state a
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading;

            (d) use reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of a registration statement at the earliest
practicable moment;

            (e) if reasonably requested by the managing underwriters or a
selling Stockholder, promptly incorporate in a prospectus supplement or
post-effective amendment such 


                                       12
<PAGE>   13

information as the managing underwriters or a selling Stockholder agree should
be included therein, subject to the last sentence of Section 4.05(a); and
promptly make all required filings of such prospectus supplement or
post-effective amendment as soon as notified of the matters to be incorporated
in such prospectus supplement or post-effective amendment;

            (f) prior to any public offering of Stock or Equity Securities,
register or qualify or cooperate with the selling Stockholders, the managing
underwriters, if any, and their respective counsel in connection with the
registration or qualification of such shares for offer and sale under the
securities or "blue sky" laws of such jurisdictions within the United States as
any seller or underwriter reasonably requests in writing and do any and all
other acts or things reasonably necessary or advisable to enable the disposition
in such jurisdictions of the shares of Common Stock covered by the applicable
registration statement; provided that the Company will not be required to
qualify generally to do business in any jurisdiction where it would not
otherwise be required to be so qualified or to take any action which would
subject itself to taxation (other than a nominal amount) in any such
jurisdiction or to general service of process in any jurisdiction where it is
not then so subject;

            (g) cooperate with the selling Stockholders and the managing
underwriters, if any, to facilitate the timely preparation and delivery of
certificates representing shares of Common Stock to be sold and not bearing any
restrictive legends; and enable such shares to be in such denominations and
registered in such names as the managing underwriters may request at least two
business days prior to any sale of shares to the underwriters;

            (h) use its best efforts to cause the shares covered by the
applicable registration statement to be listed or registered with or approved by
any stock exchange or quotation system on which the shares of Stock or Equity
Securities are then listed and by such governmental agencies or authorities
within the United States as may be reasonably necessary to enable the seller or
sellers thereof or the underwriters, if any, to consummate the disposition of
such shares;

            (i) if any fact contemplated by Section 4.05 (c)(E) shall exist,
prepare a supplement or post-effective amendment to the applicable registration
statement or the related prospectus or any document incorporated therein by
reference or file any other required document so that, as thereafter delivered
to the purchasers of the shares of Stock or Equity Securities being sold
thereunder, such prospectus will not contain any untrue statement of a material
fact or omit to state any material fact necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading;

            (j) provide a CUSIP number for all shares of Stock or Equity
Securities, no later than the effective date of the applicable registration
statement;

            (k) enter into such agreements (including an underwriting agreement)
and take all such other actions in connection therewith in order to expedite or
facilitate the disposition of such shares of Stock or Equity Securities and in
such connection, whether or not an underwriting agreement is entered into and
whether or not the registration is an underwritten 


                                       13

registration: (A) make such representations and warranties to the holders of
such shares and the underwriters, if any, in form, substance and scope as are
customarily made by issuers to underwriters in primary underwritten offerings;
(B) obtain opinions of counsel to the Company (including counsel which may be an
employee of the Company) and updates thereof which counsel and opinions (in
form, scope and substance) shall be reasonably satisfactory to the managing
underwriters, if any, covering the matters customarily covered in opinions
requested by such holders and underwriters; (C) obtain "cold comfort" letters
and updates thereof from the Company's independent certified public accountants,
addressed to the selling holders and the underwriters, if any, such letters to
be in customary form and covering matters of the type customarily covered in
"cold comforts" letters to underwriters in connection with primary underwritten
offerings; (D) if any underwriting agreement is entered into, the same shall set
forth in full the indemnification provisions and procedures of Section 4.06 with
respect to all parties to be indemnified pursuant to such Section 4.06; and (E)
the Company shall deliver such documents and certificates as may be reasonably
requested by the holders of the Stock or Equity Securities being sold and the
managing underwriters, if any, to evidence compliance with clause (A) hereof and
with any customary conditions contained in the underwriting agreement or other
agreement entered into by the Company. The above shall be done at each closing
under such underwriting or similar agreement or as and to the extent otherwise
reasonably required thereunder;

            (l) make available for inspection during normal business hours by a
representative of each Stockholder, any underwriter participating in any
disposition pursuant to a registration statement and any attorney or accountants
retained by such selling Stockholders or underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors and employees to supply all information
reasonably requested by such representative, underwriter, attorney or accountant
in connection with such registration statement; provided, that such
Stockholders, underwriters, attorneys or accountants execute prior thereto an
agreement with the Company that all such records, information or document shall
be kept confidential by such persons unless (A) disclosure of such records,
information or documents is required by law or by court or administrative order,
or (B) such records, information or documents are or become (but only when they

(or 90 days, if such period is a fiscal year) (A) commencing at the end of any
fiscal quarter in which shares of Stock or Equity Securities are sold to
underwriters in an underwritten offering, or (B) if not sold to underwriters in
such an offering beginning with the first month of the Company's first fiscal
quarter commencing after the effective date of the registration statement, which
statements shall cover such 12-month periods. 

            The Company may require each Stockholder who is a party hereto as to
which any registration is being effected to furnish to the Company such
information and undertakings


                                       14
<PAGE>   15

as it may reasonably request regarding such Stockholder and the distribution of
such securities as the Company may from time to time reasonably request in
writing.

            Each Stockholder who is a party hereto agrees (i) that upon receipt
of any notice from the Company of the happening of any event of the kind
described in Section 4.05 (c)(E) such Stockholder will forthwith discontinue
such Stockholder's disposition of shares of Stock or Equity Securities pursuant
to the registration statement relating to such shares until such Stockholder's
receipt of the copies of the supplemented or amended prospectus contemplated by
Section 4.05(i) and, if so directed by the Company, will deliver to the Company
(at the Company's expense) all copies then in such Stockholder's possession of
the prospectus relating to such shares current at the time of receipt of such
notice and (ii) that such Stockholder will immediately notify the Company, at
any time when a prospectus relating to the registration of such shares is
required to be delivered under the Securities Act, of the happening of any event

Company in writing for inclusion in such prospectus contains an untrue statement
of a material fact or omits to state any material fact required to be stated
therein, or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

            Section 4.05 Indemnification and Contribution. (a) Indemnification.
(i) In the event of any registration under the Securities Act of any shares of
Stock pursuant to this Article 4, the Company hereby agrees to indemnify and

underwriter, and their respective officers, directors, stockholders, members,
partners and affiliates, in connection with such offer or sale against such
losses, claims, damages, liabilities, costs or expenses (including reimbursement
for reasonable legal and other expenses) to which any such person may become
subject under the Securities Act or otherwise insofar as such losses, claims,
damages, liabilities, costs or expenses arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such shares were registered under the
Securities Act, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, or any
application or other filing under any "blue sky" or state securities law, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, provided that the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage, liability (or action or proceeding in respect thereof), cost or
expense arises out of or is based upon an untrue statement or omission or
alleged omission made in such registration statement, preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement, or application or
other filing, in reliance upon and in conformity with written information
furnished to the Company through an instrument duly executed by any holder of
the Company's securities or underwriter.

      (ii)  In the event of any registration under the Securities Act of any
            shares of Common Stock pursuant to this Article 4, each Stockholder
            whose shares of Stock or Equity Securities are included in such
            registration hereby agrees to indemnify and hold harmless, but only
            for an amount, with respect to such Stockholder, not in excess of
            the net proceeds realized by 


                                       15
<PAGE>   16

            such Stockholder from the sale of its shares of Common Stock
            registered pursuant to such registration statement, both the Company
            and its officers, directors, stockholders and affiliates, and any
            underwriter, and their respective officers, directors, stockholders
            and affiliates, in connection with such offer or sale against such
            losses, claims, damages, liabilities, costs or expenses (including
            reimbursement for reasonable legal and other expenses) to which any
            such person may become subject under the Securities Act or otherwise
            insofar as such losses, claims, damages, liabilities, costs or
            expenses arise out of or are based solely upon any untrue statement
            or alleged untrue statement of any material fact contained in any
            registration statement under which such shares were registered under
            the Securities Act, any preliminary prospectus, final prospectus or
            summary prospectus contained therein, or any amendment or supplement
            thereto, or any application or other filing under any "blue sky" or
            state securities law, or any omission or alleged omission to state
            therein a material fact required to be stated therein or necessary
            to make the statements therein, in light of the circumstances under
            which they were made, not misleading, to the extent that such untrue
            statement or omission or alleged omission made in such registration
            statement, any such preliminary prospectus, final prospectus,
            summary prospectus, amendment or supplement, or application or other
            filing, is contained in any written information furnished to the
            Company through an instrument duly executed by such holder.

            (b) Contribution. (i) If the indemnification provided for in Section
4.06(a) is unavailable to persons to be indemnified pursuant thereto in respect
of any losses, claims, damages, liabilities, costs or expenses referred to
therein, then the Company, in lieu of indemnifying such person, shall contribute
to the amount paid or payable by such person as a result of such losses, claims,
damages, liabilities, costs or expenses, in such proportion as is appropriate to
reflect the relative fault of the Company and such persons in connection with
the actions which resulted in such losses, claims, damages, liabilities, costs
or expenses, as well as any other relevant equitable considerations. The
relative fault of the Company and such persons shall be determined by reference
to, among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact, has been made by, or relates to information supplied by,
the Company or such persons, and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such action. The amount
paid or payable by a party as a result of the losses, claims, damages,
liabilities, costs and expenses referred to above shall be deemed to include any
legal or other fees or expenses reasonably incurred by such party in connection
with any investigation or proceeding.

      (ii)  The parties hereto agree that it would not be just and equitable if
            contribution pursuant to this Section 4.06(b) were determined by pro
            rata allocation or by any other method of allocation which does not
            take account of the equitable considerations referred to in the
            immediately 


                                       16
<PAGE>   17

            preceding paragraph. Notwithstanding the provisions of this Section
            4.06(b), an indemnified person shall not be required to contribute
            any amounts in excess of the amount by which the total price at
            which the shares of Stock or Equity Securities were sold by such
            indemnified person and distributed to the public exceeds the amount
            of any damages which such indemnified person has otherwise been
            required to pay by reason of such untrue or alleged untrue statement
            or omission or alleged omission and provided, however, that such
            Stockholder's aggregate liability shall be limited to the net
            proceeds realized by such Stockholder in such offering. No person
            guilty of fraudulent misrepresentation (within the meaning of
            Section 11(f) of the Securities Act) shall be entitled to
            contribution from any person who was not guilty of such fraudulent
            misrepresentation.

      (iii) If indemnification is available under this Section 4, the Company
            shall indemnify each indemnified party to the full extent provided
            herein without regard to the relative fault of the Company or the
            indemnified party or any other equitable consideration provided for
            in this Section 4.06(b).

      (iv)  In the event that any provisions of an indemnification clause in an
            underwriting agreement executed by or on behalf of a holder differs
            from a provision in this Article IV, such provision in the
            underwriting agreement shall determine such holder's rights in
            respect thereof. 

                                   ARTICLE V.

                      CERTAIN REPRESENTATIONS AND COVENANTS

            Section 5.01 Stockholder Representation. Each Stockholder represents
and warrants as to itself that, in the case of the Wolf Holders, as of the
Closing Date and in the case of the other Interliant Holders as of the date such
Interliant Holder becomes a Stockholder under this Agreement (after giving
effect to all transactions occurring on or as of such date) such Stockholder is
not a party with any other Person to any other agreement with respect to the
holding, voting, acquisition or disposition of shares of Stock except as
previously disclosed to the other Stockholders.

            Section 5.02 Company Representation. The Company represents and
warrants that as of the Closing Date (after giving effect to all transactions
occurring on or as of the Closing Date) (i) it is not a party with any other
Person to any other agreement with respect to the holding, voting, acquisition
or disposition of shares of Stock or Equity Securities to the other
Stockholders, and (ii) it has not granted to any other Person any other
registration rights with respect to capital stock of the Company, and no holder
of any capital stock of the Company shall have as of the date hereof any right
to require registration of any capital stock of the Company under the Securities
Act or to include any security in any registration statement filed by the
Company under the Securities Act except pursuant hereto; provided, however, that
the Company 


                                       17
<PAGE>   18

is a party to the Registration Rights Agreement dated as of December 8, 1997,
between the Company and WHO and the Investors Agreement dated as of January 28,
1999, between the purchasers of the Preferred Stock, WHO and the Company (the
"Prior Agreements"). The Prior Agreements remain in full force and effect except
as modified by Section 4.01(b) hereof.

            Section 5.03 Lock-up Agreement. The Interliant Holders agree with
the Company to execute and deliver to the underwriters in connection with the
Company's initial public offering, a lock-up agreement in customary form,
restricting the transfer by the Interliant Holders of shares of Common Stock for
a period of not more than 180 days following the closing of such initial public
offering, provided that the lock-up period for any Interliant Holder shall not
be longer than the lock-up period applicable to WHO.

            Section 5.04 Registration Statement on Form S-8. The Company agrees
to file a Registration Statement on Form S-8 with the Securities and Exchange
Commission promptly upon completion of the initial public offering of Company's
Common Stock in order to register the Company's 1998 Stock Option Plan (the
"Plan") and the shares of Common Stock issuable upon exercise of Options granted
pursuant to the Plan.

                                  ARTICLE VI.

                                  MISCELLANEOUS

            Section 6.01 Injunctive Relief. It is acknowledged that it will be
impossible to measure in money the damages that would be suffered if the parties
fail to comply with certain of the obligations imposed on them by this
Agreement, including, without limitation, those obligations set forth in Article
II, Article III, Article IV and Article V and that in the event of any such
failure, an aggrieved Person will be irreparably damaged and will not have an
adequate remedy at law. Any such Person shall, therefore, be entitled to
injunctive relief and/or specific performance to enforce such obligations, and
if any action should be brought in equity to enforce any of such provisions of
this Agreement, none of the parties hereto shall raise the defense that there is
an adequate remedy at law.

            Section 6.02 Further Assurances. Each party hereto shall do and
perform or cause to be done and performed all such further acts and things and
shall execute and deliver all such other agreements, certificates, instruments
and documents as any other party hereto reasonably may request in order to carry
out the intent and accomplish the purposes of this Agreement and the
consummation of the transactions contemplated hereby.

            Section 6.03 Governing Law. This Agreement shall be construed and
enforced in accordance with, and the rights of the parties shall be governed by,
the laws of the State of New York.

            Section 6.04 Entire Agreement; Amendment; Waiver. This Agreement (i)
contains the entire agreement among the parties hereto with respect to the
subject matter hereof, (ii) supersedes all prior written agreements and
negotiations and oral understandings, if any, with respect thereto, (iii) may
not be amended or supplemented except by an instrument or 


                                       18
<PAGE>   19

counterparts thereof in writing signed by the Company and WHO, and to the extent
that any such amendment or supplement adversely affects the holders of the
Preferred Stock, the Wolf Holders or the Interliant Holders, by a majority in
interest of the holders of the Preferred Stock, a majority in interest of the
Wolf Holders and a majority in interest the Interliant Holders then holding
Stock or Equity Securities and adversely affected by such amendment or
supplement. No waiver of any term or provision shall be effective unless in
writing signed by the party to be charged and such waiver shall not be effective
to any other provision of this Agreement. Notwithstanding the foregoing, no
written instrument shall be required to be signed by any Stockholder in
connection with the amendment of Schedule I to add the names of exercising
holders of Options, shares delivered pursuant to Section 3.01(b) of the Purchase
Agreement or the name of Seller and any Unconverted Shares delivered to Seller.

            Section 6.05 Binding Effect. This Agreement shall be binding on and
inure to the benefit of the parties hereto and, subject to the terms and
provisions hereof, their respective legal representatives, successors and
permitted assigns.

            Section 6.06 Invalidity of Provision. The invalidity or
unenforceability of any provision of this Agreement in any jurisdiction shall
not affect the validity or enforceability of the remainder of this Agreement in
that jurisdiction or the validity or enforceability of this Agreement, including
that provision, in any other jurisdiction.

            Section 6.07 Counterparts. This Agreement may be executed
simultaneously in two or more counterparts, all of which taken together shall be
deemed but one and the same instrument.

            Section 6.08 Notices. All notices and other communications provided
for or given or made hereunder shall be in writing (including delivery by
facsimile transmission) and, unless otherwise provided herein, shall be deemed
to have been given when received by the party to whom such notice is to be given
at its address set forth on Schedule I, or such other address for the party as
shall be specified by notice given pursuant hereto.

            Section 6.09 Headings. The descriptive headings of the several
paragraphs of this Agreement are inserted for convenience only and do not
constitute part of this Agreement.

Charterhouse Equity Partners III, L.P.
and Chef Nominees Limited

Attention: Thomas C. Dirks

                              Re: Web Hosting Organization LLC

Dear Tom:

     Once the Limited Liability Company Agreement (the "Agreement") for Web 
Hosting Organization LLC ("WHO") is fully executed, it is our understanding 
that the following events will then take place:

     1.   A Delaware "C" corporation will be formed and will be known as
          SAGE Networks, Inc. ("SAGE").

     2.   The Board of Directors of SAGE will consist initially of seven
          members, three of whom will be designated by WHO Management LLC
          ("Management") and the other four will be designated by Charterhouse
          Equity Partners III, L.P. and Chef Nominees Limited (collectively
          "CEP Members").

     3.   Unless we and the CEP Members all agree, the only business SAGE will
          be involved in will be acquiring and operating businesses in the 
          web hosting industry.

     4.   We will mutually select the initial Chief Executive Officer and the
          initial Chief Financial Officer for SAGE.

     5.   SAGE will provide for an employee stock option plan and will allocate
          to that plan 5% of its common stock then outstanding, from time to
          time, on a fully diluted basis.

     6.   CEP Members and Management will vote the shares of WHO in SAGE to 
          cause its directors to effectuate all of the above.

     Kindly sign below confirming that this letter reflects the CEP Members'
understanding of the events which will follow the execution of the Agreement.

                                             Sincerely,



                                             /s/ Leonard J. Fassler, Manager

                                   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:

          on personal cars

     -    Airline club memberships

     -    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.

timetable.

5 LICENSE FEE

5.1 In consideration of the rights granted herein, Licensee shall pay Portal the
license fee specified in Schedule A on the Effective Date.

6 MAINTENANCE AND TECHNICAL SUPPORT

support in accordance with Portal's Gold Level Support Policy, a current copy of
which is provided at Schedule B. The first annual Gold Level Maintenance Support
payment shall be due upon the earlier of: (i) completion of implementation
services, or (ii) 180 days from the Effective Date hereof, whichever shall be
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
Portal Software and (ii) product Updates that Portal in its discretion makes

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
as specified in Portal's user documentation or other causes beyond the control

which may be necessary to use the Portal Software.

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
Portal gives Licensee written notice of such breach; or Portal may terminate
this Agreement immediately upon notice if Licensee breaches any of its
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
assignment for the benefit of creditors, or becomes subject to direct control of
a trustee, receiver or similar authority, unless Licensee remains current on all
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
this Agreement for any reason whatsoever, Licensee shall return the Portal
Software, derivative works and all copies thereof, in whole or in part, all
related Documentation and all copies thereof, and any other Confidential
Information in its possession. Licensee shall furnish Portal with a certificate
signed by an executive officer of Licensee verifying that the same has been
done.


7.7 Termination is not an exclusive remedy and all other remedies will be
available whether or not termination occurs.

                        Portal Proprietary & Confidential


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
representatives shall be entitled to review and audit such books and records
and/or Licensee's compliance with the provisions of this Agreement from time to


Portal SLSA                                                         Page 3 of 5

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

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.

12.1 Each Party acknowledges that the Confidential Information constitutes
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
Agreement and it will not disclose, or permit to be disclosed, the same directly

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:

                                                                        Page B 3

                                           GUIDELINES, POLICIES AND DEFINITIONS


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.

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.

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.

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

II.   PRODUCT LICENSE

2.1   RIGHTS GRANTED

      A. Vantive grants to Client a non-exclusive license to use the Products
Client obtains under this Agreement, as follows:

          i.   to use the Products solely for Client's own internal data
               processing operations on the Designated System or on a backup
               system if the Designated System is inoperative, up to any
               applicable maximum number of designated Users or Concurrent Users
               consistent with applicable licensed use limitations. Client may
               not relicense the Products or use the Products for third party
               training, commercial time-sharing, rental or service bureau use;

         ii.   to use the Documentation provided with the Products in support of
               Client's authorized use of the Products;

        iii.   to copy the Products for archival or backup purposes; no other
               copies shall be made without Vantive's prior written consent. All
               titles, trademarks, copyright and restricted rights notices shall
               be reproduced in such copies. All archival and backup copies of
               the Products are subject to the terms of this Agreement; and

         iv.   to modify the Products or combine them with other software
               products. The Products or such portions thereof included in such
               software products shall remain the property of Vantive and shall
               be subject to the terms of this Agreement.

           Client shall not copy or use the Products (including the
           Documentation) except as otherwise specified in this Agreement or an
           Order Form. Client shall have the right to allow Client's third party
           agents ("Agents") to use the Products for Client's internal use
           purposes so long as Client ensures that Agents use the Products in
           accordance with the terms of this Agreement.


<PAGE>   2



      B.   Client agrees not to cause or permit the reverse engineering,
           disassembly or decompilation of the Products. In jurisdictions where
           a right to reverse engineer is provided by law unless information is
           available about products in order to achieve interoperability,
           functional compatibility, or similar objectives, Client agrees to
           submit a detailed written proposal to Vantive concerning Client's
           information needs before engaging in reverse engineering. Vantive
           may, in its sole discretion, propose to Client terms and conditions
           under which it is willing to make such information available.

      C.   Vantive or its licensor's shall retain all title, copyright, trade
           secrets, patents, trademarks and other proprietary rights in the
           Products and all modifications, enhancements, and other works
           derivative of the Products. Client does not acquire any rights,
           express or implied, in the Products, other than those specified in
           this Agreement.

      D.   The Products are not intended for use in any nuclear, aviation, mass
           transit, medical, life support or other inherently dangerous
           applications or support thereof. It shall be Client's responsibility
           to take all appropriate measures to ensure the safe use of such
           applications if the Products are used for such purposes, and Vantive
           disclaims liability for any damages caused by such use of the
           Products and Client agrees to indemnify, defend and hold Vantive
           harmless for all claims arising from or related to such use.

      E.   Other Vantive products and/or runtime versions of third party
           software, including but not limited to relational database management
           systems, may be embedded in or delivered with Vantive Products
           licensed under this Agreement ("Ancillary Product"). Client shall be
           limited to use of Products licensed under this Agreement. Client's
           right to use any Ancillary Product shall be only as described in the
           Order Form or Documentation and limited to the use necessary to
           implement the Vantive Product ordered, as designated on the Order
           Form. Client shall have no right to use such Ancillary Product other
           than as necessary for the licensed ordinary use of the Vantive
           Product ordered and grants Vantive's licensors the right to protect
           its interests under this Agreement and agrees that such licensors are
           benefited by the provisions of this Agreement.

      F.   As an accommodation to Client, Vantive may supply Client with Limited
           Production Products. These Products are not suitable for production
           use.



2.2   TRANSFER AND ASSIGNMENT

      A.   Client may transfer a Product license within its organization upon
           written notice to Vantive; transfers are subject to the terms and
           fees, if any, specified in Vantive's transfer policy in effect at the
           time of the transfer.

      B.   Client may not assign this Agreement to a third party (i.e. a legal
           entity separate from Client) without the prior written consent of
           Vantive, and any such attempt shall be void. Vantive shall not
           unreasonably withhold such consent.

2.3   VERIFICATION

      On Vantive's written request, not more frequently than annually, Client
      shall furnish Vantive with a signed certification (a) verifying that the
      Products are being used pursuant to the terms of this Agreement and
      applicable Order Form; and (b) listing the locations, and types of the
      Designated Systems on which the Products are run.

      Vantive may, at its expense, audit Client's use of the Products. Any such
      audit shall be conducted during regular business hours at Client's
      facilities and shall not unreasonably interfere with Client's business.
      Audits shall be conducted no more than once annually.

III.  PROFESSIONAL SERVICES

3.1   CUSTOMER SUPPORT SERVICES

      Customer Support services ordered by Client will be provided subject to
      Vantive's Customer Support policies and fees in effect on the date
      Customer Support is ordered or renewed. Reinstatement of lapsed Customer
      Support Services is subject to Vantive's Customer Support reinstatement
      fees in effect on the date Customer Support is re-ordered, subject to
      payment by Client of the applicable fee. Client may obtain Customer
      Support Services for pre-production releases of Products and Limited
      Production Products on a time and materials basis.

3.2   CONSULTING AND TRAINING SERVICES

      Vantive will provide consulting and training services agreed to by the
      parties under the terms of this Agreement. All consulting services shall
      be billed on a time and materials basis unless the parties expressly agree
      otherwise in writing. Any consulting or training services acquired from
      Vantive shall be bid separately from the Product licenses and Client may
      acquire either Product licenses or consulting services without acquiring
      the other.

      Client agrees if Client hires any Vantive employee, consultant or
      subcontractor within twelve (12) months from the last date such person
      provided services hereunder, Client agrees to pay Vantive 50% of the first
      year's total compensation package offered by Client to that Vantive
      employee, consultant or subcontractor.

3.3   INCIDENTAL EXPENSES
      For any on site services requested by Client, Client shall reimburse
      Vantive for actual, reasonable travel and out-of pocket expenses incurred.

IV.   TERM AND TERMINATION

4.1   TERM

      If not otherwise specified on the Order Form, each Product license granted
      under this Agreement shall remain in effect perpetually, unless terminated
      as provided in Section 4.2 or 4.3 below or otherwise as provided herein.

4.2   TERMINATION BY CLIENT

      Client may terminate any Product license at any time; however, termination
      shall not relieve Client's obligations specified in Section 4.4.

4.3   TERMINATION BY VANTIVE

      Vantive may terminate this Agreement or any Product license upon written
      notice if Client breaches this Agreement and fails to correct the breach
      within 30 days following written notice specifying the breach.

4.4   EFFECT OF TERMINATION

      Termination of this Agreement or any license shall not limit either party
      from pursuing any other remedies available to it, including injunctive
      relief, nor shall such termination relieve Client's obligation to pay all
      fees that have accrued or are otherwise owed by Client under any Order
      Form or other similar ordering document under this Agreement. The parties'
      rights and obligations under Sections 2.1.B, 2.1.C, 2.1.D, 2.1.E and
      2.2.B, and Articles IV, V, VI,VII, and VIII shall survive termination of
      this Agreement.

4.5   HANDLING OF PRODUCTS UPON TERMINATION

      If a license granted under this Agreement expires or otherwise terminates,
      Client shall (a) cease using the applicable Products, and (b) certify to
      Vantive within one month after expiration or termination that Client has
      destroyed or has returned to Vantive the Products and all copies. This
      requirement applies to copies in all forms, partial and complete, in all
      types of media and computer memory, and whether or not modified or merged
      into other materials. Before returning Products to Vantive, Client shall
      acquire a Return Material Authorization ("RMA") number from Vantive.

V.    INDEMNITY, WARRANTIES, REMEDIES

5.1   INFRINGEMENT INDEMNITY

      Vantive will defend and indemnify Client against a claim that Products
      furnished and used within the scope of this Agreement infringe a United
      States copyright or patent provided that: (a) Client notifies Vantive in
      writing within 30 days of the claim; (b) Vantive has sole control of the
      defense and all related settlement negotiations; and (c) Client provides
      Vantive with the assistance, information and authority necessary to
      perform Vantive's obligations under this section. Reasonable out-of-pocket
      expenses incurred by Client in providing such assistance will be
      reimbursed by Vantive.

      Vantive shall have no liability for any claim of infringement based on;
      (a) use of a superseded or altered release of Products if the infringement
      would have been avoided by the use of a current unaltered release of the
      Products that Vantive provides to Client; or (b) the combination,
      operation or use of any Products furnished under this Agreement with
      software, hardware or other materials not furnished by Vantive if such
      infringement would have been avoided by the use of the Products without
      such software, hardware or other materials.

      In the event the Products are held or are believed by Vantive to infringe,
      Vantive shall have the option, at its expense, to (a) modify the Products
      to be non infringing, (b) obtain for Client a license to continue using
      the Products; or (c) terminate the license for the infringing Products and
      refund the license fees paid for those Products, prorated over a five year
      term from the Commencement Date. This Section 5.1 states Vantive's or
      Vantive's licensor's entire liability and Client's exclusive remedy for
      infringement or any intellectual property warranty.

5.2   WARRANTIES AND DISCLAIMERS

      A. PRODUCT WARRANTIES

         Vantive warrants the tapes, diskettes or other media to be free of

      C. SERVICES WARRANTY

         Vantive warrants that its Customer Support and consulting services will

      D. DISCLAIMERS


         THE WARRANTIES ABOVE ARE EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES,
         WHETHER EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF
         MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

         REQUIREMENTS, THAT THE PRODUCTS WILL OPERATE IN THE COMBINATIONS WHICH
         CLIENT MAY SELECT FOR USE, THAT THE OPERATION OF THE PRODUCTS WILL BE
         UNINTERRUPTED OR ERROR-FREE, OR THAT ALL PRODUCT ERRORS WILL BE

            VANTIVE POLICY REGARDING INVOICING FOR CUSTOMARY TRAVEL
                              AND LIVING EXPENSES


Vantive invoices its customers for customary travel and living expenses incurred
in the process of providing consulting, training or customer support services
that have been request by Vantive's customers.

The purpose of this document is to describe the guidelines that Vantive has
established for its consultants and other personnel ("consultants" hereafter in
this document) regarding travel and living expenses and Vantive's policies
regarding invoicing Vantive customers for such travel and living expenses.

Vantive consultants are encouraged to be prudent at all times regarding
incurring travel and living expenses. Special guidelines for travel and living
expenses and other administrative is described below.

We hope that this document provides you with useful information. If you have any
questions, please contact Vantive's Director of Finance at Vantive's corporate
headquarters of the Vantive regional consulting manager who handles consulting
services for your account.

GUIDELINES FOR TRAVEL AND LIVING EXPENSES

         Air Travel

         Vantive consultants travel non-stop coach class whenever possible.
         Vantive's travel agency has been instructed to book Vantive consultants
         on the lowest fare for non-stop flights that result in the consultant
         traveling between the hours of 6:00 a.m. and 11:00 p.m. In general,
         Vantive consultants are not asked to incur extra stops or take
         "red-eye" flights in order to reduce the cost of air travel.

         Overnight Lodging

         Vantive consultants are encouraged to ask Vantive's customers for
         recommendations regarding lodging. Vantive consultants attempt to stay
         in accommodations that are located close to the customer's site and in
         accommodations where the customer has negotiated preferred rates for
         lodging.

         Meals

         Vantive consultants are allowed to submit either tactual expenses for
         meals, or a per diem meal rate. For example, the Internal Revenue
         Service standard per diem (a flat rate which includes amounts spent on
         food, beverages, taxes and related tips) for meal allowance is $38 a
         day for Santa Clara County, California. There are designated per diem
         meal rates for other locations in the United States. Please check the
         attached per diem chart for guidelines. Vantive consultants are
         encouraged to keep their daily meal expenses to $35 or less per day.

         The default method for handling meal expenses may vary depending upon
         the specific consultant who is performing work on a particular project.
         If you (the customer) have a preference for actual expenses or per
         diem, please inform the Vantive consulting manager who is responsible
         for your project prior to the commencement of the project.

         Incidental

         Incidental expenses include costs for laundry, cleaning and tips for
         services. Incidental expenses are normally not charged on consulting
         engagements where the consultant is on the customer's site for less
         than two weeks consecutively.

                                    EXHIBIT A



         Automobile.  Public Transportation

         Vantive consultants use their judgement in determining the use of
         rented automobiles, tax, subway, etc. when traveling between airports,
         train stations, places of overnight lodging and customer sites.
         Automobile rentals are usually made on special corporate rates from
         either Hertz, Avis or Budget rental car services.

         Mileage Rate, Parking Fees and Tolls

         The standard mileage rate for the cost of operating a consultant's
         automobile is 30 cents per mile for all business miles. In addition to
         using the standard mileage rate, consultants may submit all
         business-related parking fees and tolls.

         Other expenses that are directly related to the services provided by
         Vantive

         Vantive consultants are encouraged to make prudent purchasing decisions
         for materials that are directly related to the providing of consulting,
         training and customer support services. Expenses for these types of
         materials are invoiced to Vantive's customers.

         Other expenses that are not directly related to the services provided
         by Vantive

         Vantive does not invoice its customers for expenses incurred by Vantive
         consultants for movies, shows and other types of expenses that are not
         directly related to the providing of services to Vantive's customers.

Travel Expense Reports, Receipts, Administrative Costs and Invoices

Vantive consultants are required to submit travel expense reports for all travel
associated with Vantive Company business. The amounts to be invoiced to
customers are clearly indicated on the expense reports. Vantive consultants are
required to submit receipts for all expenses over $15. Vantive uses relevant
consultant expense reports in computing the amounts that are invoiced to
Vantive's customers. Copies of relevant expense reports are included with
invoices for travel and living expenses. Receipts are not included along with
the invoices. Receipts are provided upon request. If receipts are requested, a
15% administrative cost is added to the expenses that are invoiced to the
customer. If receipts are not requested, the travel and living expenses are
invoiced to the customer at Vantive's out of pocket cost.

Currency Conversions

For international expenses that require currency conversion, Vantive makes
reasonable efforts to compute the currency conversion at the average rate that
was in effect for the relevant international currencies during the time that the
Vantive employee was incurring international expenses.

Timing of Invoices

Vantive invoices its customers for travel and living expenses as soon as
possible after the receipt of the relevant expense reports from Vantive
consultants. These invoices are usually sent to customers within the two weeks
of the conclusion of the trip to the customer site by the Vantive consultant.

                     [UUNET Technologies, Inc. Letterhead]


                 MASTER DISCOUNTED INTERNET SERVICES AGREEMENT

This Master Internet Services Agreement ("Agreement") is made by and between

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.

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.

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

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.

of these meetings shall be followed by an executive meeting at which at least
one officer of Customer attends.

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.

     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

     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 **.

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 ** for internet traffic in years two and three of the
term commitment, ** of any  **  shall be purchased from UUNET. If the **
requirement is not met, Customer will pay UUNET ** in the amount of ** for each
** by which Customer has **  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 ** from UUNET in an amount equal to or greater than **.

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.

7.  The Service Level Agreement ("SLA") for this service, which is made a part
    of this Agreement, is set forth at www.uu.net/customers/sla/terms.html and
    applies only to customers agreeing to a Term Commitment of at least one
    year. UUNET reserves the right to amend the SLA from time to time effective
    upon posting of the revised SLA to the URL or other notice to Customer;
    provided, that in the event of any amendment resulting in a material
    reduction of the SLA's service levels or credits, Customer may terminate
    this Agreement without penalty by providing UUNET written notice of
    termination during the 30 days following notice of such amendment. The SLA
    sets forth Customer's sole remedies for any claim relating to this service
    or the UUNET Network, including any failure to meet any guarantee set forth
    in the SLA. UUNET's records and data shall be the basis for all SLA
    calculations and determinations. Notwithstanding anything to the contrary,
    the maximum amount of credit in any calendar month under the SLA shall not
    exceed the Monthly Fee and/or Start-up Charge which, absent the credit,
    would have been charged to UUNET service that month (collectively the "UUNET
    Fees"); provided, that the maximum amount of credit for failure to meet the
    Availability Guarantee shall not exceed the sum of (a) the UUNET Fees, plus
    (b) the telephone company line charge which, absent the credit, would have
    been charged for such month. If Customer receives credits under this Section
    in three consecutive months, Customer may terminate without penalty
    (including, without limitation, the early termination penalty described
    above in paragraph 6) by providing UUNET written notice of termination in
    the fourth month.

8.  Neither party may use the other party's name, trademarks, tradenames or
    other proprietary identifying symbols without the prior written approval of
    the other party. Neither party may assign or transfer any of its rights or
    obligations under this Agreement without the express, prior written consent
    of the other party; provided, that either party may assign or transfer this
    Agreement to any affiliate of such party upon advance written notice to the
    other party. 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.

9.  These Terms and Conditions are applicable to Services purchased pursuant to
    the Master Discounted Internet Services Agreement between UUNET
    Technologies, Inc., and Customer dated February 17, 1999 and shall prevail
    notwithstanding any variance with terms and conditions of any order
    submitted. Activation of service shall indicate UUNET's acceptance of this
    Agreement. Use of the UUNET Network constitutes acceptance of these Terms
    and Conditions.

                                   ELIGIBILITY

                  All Eligible Persons are eligible to receive a grant of an
Option under the Plan. The Committee shall, in its sole discretion, determine
and designate from time to time those Eligible Persons who are to be granted an
Option.


                                   ARTICLE IV

                                 ADMINISTRATION

                  4.1 Committee Members. The Plan shall be administered by a
Committee comprised of no fewer than two persons selected by the Board, or by
the full Board. Solely to the extent deemed necessary or advisable by the Board,
each Committee member shall meet the definition of a "nonemployee director" for
purposes of such Rule 16b-3 under the Exchange Act and of an "outside director"
under Section 162(m) of the Code.

                  4.2 Committee Authority. Subject to the express provisions of 
the Plan, the Committee shall have the authority, in its discretion, to
determine the Eligible Persons to whom an Option shall be granted, the time or
times at which an Option shall be granted, the number of shares of Common Stock
subject to each Option, the Option Price of the shares subject to each Option
and the time or times when each Option shall become exercisable and the duration
of the exercise period. Subject to the express provisions of the Plan, the
Committee shall also have discretionary authority to interpret the Plan, to
prescribe, amend and rescind rules and regulations relating to it, to determine
the details and provisions of each Stock Option Agreement, and to make all the
determinations necessary or advisable in the administration of the Plan. All
such actions and determinations by the Committee shall be conclusively binding
for all purposes and upon all persons. No Committee member shall be liable for
any action or determination made in good faith with respect to the Plan, any
Option or any Stock Option Agreement entered into hereunder.


                                   ARTICLE V

                         SHARES OF STOCK SUBJECT TO PLAN

                  5.1 Number of Shares. Subject to adjustment pursuant to the
provisions of Section 5.2 hereof, the maximum number of shares of Common Stock
which may be issued and sold hereunder shall be 1,500,000 shares. Shares of
Common Stock issued and sold under the Plan may be either authorized but
unissued shares or shares held in the Company's treasury. Shares of Common Stock
covered by an Option that shall have been exercised shall not again be

                                       3
<PAGE>   4
available for an Option grant. If an Option shall terminate for any reason
(including, without limitation, the cancellation of an Option pursuant to
Section 6.6 hereof) without being wholly exercised, the number of shares to
which such Option termination relates shall again be available for grant
hereunder.

                  5.2 Antidilution. In the event of a reorganization,
recapitalization, stock split, stock dividend, combination of shares, merger or
consolidation, or the sale, conveyance, or other transfer by the Company of all
or substantially all of its property, or any other change in the corporate
structure or shares of the Company, pursuant to any of which events the then
outstanding shares of Common Stock are split up or combined, or are changed
into, become exchangeable at the holder's election for, or entitle the holder
thereof to, cash, other shares of stock, or any of the consideration, or in the
case of any other transaction described in Section 424(a) of the Code, the
Committee may (i) change the number and kind of shares (including by
substitution of shares of another corporation) subject to the Options and/or the
Option Price of such shares in the manner that it shall deem to be equitable and
appropriate or (ii) provide for an appropriate and proportionate cash settlement
or distribution. In no event may any such change be made to an Incentive Stock
Option which would constitute a "modification" within the meaning of Section
424(h)(3) of the Code without the written consent of the Optionee adversely
affected thereby.


                                   ARTICLE VI

                                     OPTIONS

                  6.1 Grant of Option. An Option may be granted to any Eligible
Person selected by the Committee. The grant of an Option shall first be
effective upon the date it is approved by the Committee, except to the extent
the Committee shall specify a later date upon which the grant of an Option shall
first be effective. Each Option shall be designated, at the discretion of the
Committee, as an Incentive Stock Option or a Nonqualified Stock Option, provided
that Incentive Stock Options may only be granted to Eligible Persons who are
considered employees of the Company or any Subsidiary for purposes of Section
422 of the Code. The Company and the Optionee shall execute a Stock Option
Agreement which shall set forth such terms and conditions of the Option as may
be determined by the Committee to be consistent with the Plan, and which may
include additional provisions and restrictions that are not inconsistent with
the Plan.

                  6.2 Option Price. The Option Price shall be determined by the
Committee; provided, however, that the Option Price shall not be less than 100
percent of the Fair Market Value of a share of Common Stock on the trading date
immediately preceding the Date of Grant.

                                       4
<PAGE>   5
                  6. 3 Vesting; Term of Option. Unless otherwise specified by 
the Committee in the Stock Option Agreement for an Optionee, an Option shall
vest and become exercisable in cumulative annual installments, each of which
shall relate to one-fourth of the number of shares of Common Stock originally
covered thereby (as may be adjusted in accordance with Section 5.2 hereof), on
the first, second, third and fourth anniversaries of the Date of Grant,
respectively, provided that the Optionee remains an Eligible Person on each such
anniversary. Notwithstanding the foregoing, the Committee, in its sole
discretion, may accelerate the exercisability of any Option at any time, and an
Option may become vested and exercisable in accordance with the provisions of
Articles VIII and IX hereof. Subject to Article VIII hereof, the period during
which a vested Option may be exercised shall be ten years from the Date of
Grant, unless a shorter exercise period is specified by the Committee in the
Stock Option Agreement for an Optionee.

                  6. 4 Option Exercise; Withholding. An Option may be exercised 
in whole or in part at any time, with respect to whole shares only, within the
period permitted for the exercise thereof, and shall be exercised by written
notice of intent to exercise the Option with respect to a specified number of
shares delivered to the Company at its principal office, and payment in full to
the Company at said office of the amount of the Option Price for the number of
shares of the Common Stock with respect to which the Option is then being
exercised. Payment of the Option Price shall be made (i) in cash or by cash
equivalent, (ii) at the discretion of the Committee, in Common Stock owned by
the Optionee for more than six months on the date of exercise, valued at the
Fair Market Value of such shares on the trading date immediately preceding the
date of exercise or (iii) at the discretion of the Committee, by a combination
of such cash and such Common Stock. In addition to and at the time of payment of
the Option Price, the Optionee shall pay to the Company in cash or, at the
discretion of the Committee, in Common Stock the full amount of all federal and
state withholding and other employment taxes applicable to the taxable income of
such Optionee resulting from such exercise.

                  6. 5 Limited Transferability of Option and Nontransferability
of Option. All Options shall be nontransferable except upon the Optionee's
death, by the Optionee's will or the laws of descent and distribution. No
transfer of an Option by the Optionee by will or by laws of descent and
distribution shall be effective to bind the Company unless the Company shall
have been furnished with written notice thereof and an authenticated copy of the
will and/or such other evidence as the Committee may deem necessary to establish
the validity of the transfer. During the lifetime of an Optionee, the Option
shall be exercisable only by him, except that, in the case of an Optionee who is
legally incapacitated, the Option shall be exercisable by his guardian or legal
representative.

                  6. 6 Cancellation, Substitution and Amendment of Options. The
Committee shall have the authority to effect,

                                       5
<PAGE>   6
at any time and from time to time, with the consent of the affected Optionees,
(i) the cancellation of any or all outstanding Options and the grant in
substitution therefor of new Options covering the same or different numbers of
shares of Common Stock and having an Option Price which may be the same as or
different than the Option Price of the cancelled Options or (ii) the amendment
of the terms of any and all outstanding Options.


                                  ARTICLE VII

                            ADDITIONAL RULES FOR ISOS

                  7. 1 Ten-Percent Owners. Notwithstanding any other provisions
of this Plan to the contrary, in the case of an Incentive Stock Option granted
to a Ten-Percent Owner, (i) the period during which any such Incentive Stock
Option may be exercised shall not be greater than five years from the Date of
Grant and (ii) the Option Price of such Incentive Stock Option shall not be less
than 110 percent of the Fair Market Value of a share of Common Stock on the Date
of Grant.

                  7. 2 Annual Limits. No Incentive Stock Option shall be granted
to an Optionee as a result of which the aggregate fair market value (determined
as of the date of grant) of the stock with respect to which incentive stock
options are exercisable for the first time in any calendar year under the Plan,
and any other stock option plans of the Company, any Subsidiary or any parent
corporation, would exceed $100,000, determined in accordance with Section 422(d)
of the Code. This limitation shall be applied by taking options into account in
the order in which granted.

                  7. 3 Disqualifying Dispositions. If shares of Common Stock
acquired by exercise of an Incentive Stock Option are disposed of within two
years following the Date of Grant or within one year following the transfer of
such shares to the Optionee upon exercise, the Optionee shall, within 10 days
after such disposition, notify the Company in writing of the date and terms of
such disposition and provide such other information regarding the disposition as
the Committee may reasonably require.

                  7. 4 Other Terms and Conditions. Any Incentive Stock Option
granted hereunder shall contain such additional terms and conditions, not
inconsistent with the terms of this Plan, as are deemed necessary or desirable
by the Committee, which terms, together with the terms of this Plan, shall be
intended and interpreted to cause such Incentive Stock Option to qualify as an
"incentive stock option" under Section 422 of the Code.


                                  ARTICLE VIII

                             TERMINATION OF SERVICE

                  8. 1 Death. If an Optionee shall die at any time after the
Date of Grant and while he is an Eligible Person, the executor or administrator
of the estate of the decedent, or the person or persons to whom an Option shall
have been validly transferred in accordance with Section 6.5 hereof pursuant to
will or the laws of descent and distribution, shall have the right, during the
period ending one year after the date of the Optionee's death (subject to
Sections 6.3 and 7.1 hereof concerning the maximum term of an Option), to
exercise the Optionee's Option to the extent that it was exercisable at the date
of the Optionee's death and shall not have been previously exercised. The
Committee may determine at or after grant to make any portion of his Option that
is not exercisable at the date of death immediately vested and exercisable.

                  8. 2 Disability. If an Optionee's employment or other service
with the Company or any Subsidiary shall be terminated as a result of his
permanent and total disability (within the meaning of Section 22(e)(3) of the
Code) at any time after the Date of Grant and while he is an Eligible Person,
the Optionee (or in the case of an Optionee who is legally incapacitated, his
guardian or legal representative) shall have the right, during a period ending
one year after the date of his disability (subject to Sections 6.3 and 7.1
hereof concerning the maximum term of an Option), to exercise an Option to the
extent that it was exercisable at the date of such termination of employment or
other service and shall not have been exercised. The Committee may determine at
or after grant to make any portion of his Option that is not exercisable at the
date of termination of employment or other service due to disability immediately
vested and exercisable.

                  8. 3 Termination for Cause. If an Optionee's employment or
other service with the Company or any Subsidiary shall be terminated for cause,
the Optionee's right to exercise any unexercised portion of an Option shall
immediately terminate and all rights thereunder shall cease. For purposes of
this Section 8.3, termination for "cause" shall include, but not be limited to,
embezzlement or misappropriation of corporate funds, any acts of dishonesty
resulting in conviction for a felony, misconduct resulting in material injury to
the Company or any Subsidiary, significant activities harmful to the reputation
of the Company or any Subsidiary, a significant violation of Company or
Subsidiary policy, willful refusal to perform, or substantial disregard of, the
duties properly assigned to the Optionee, or a significant violation of any
contractual, statutory or common law duty of loyalty to the Company or any
Subsidiary. The Committee shall have the power to determine whether the Optionee
has been terminated for cause and the date upon which such termination for cause
occurs. Any such determination shall be final, conclusive and binding upon the
Optionee.

<PAGE>   8
                  8. 4 Other Termination of Service. If an Optionee's employment
or other service with the Company or any Subsidiary shall be terminated for any
reason other than death, permanent and total disability or termination for
cause, the Optionee shall have the right, during the period ending 90 days after
such termination (subject to Sections 6.3 and 7.1 hereof concerning the maximum
term of an Option), to exercise an Option to the extent that it was exercisable
at the date of such termination and shall not have been exercised. For purposes
of this Section 8.4, an Optionee shall not be considered to have terminated
employment or other service with the Company or any Subsidiary until the
expiration of the period of any military, sick leave or other bona fide leave of
absence, up to a maximum period of 90 days (or such greater period during which
the Optionee is guaranteed reemployment either by statute or contract).

                                CHANGE IN CONTROL

                  9. 1 Change in Control. Upon a "change in control" of the
Company (as defined below), each outstanding Option, to the extent that it shall
not otherwise have become vested and exercisable, shall automatically become
fully and immediately vested and exercisable, without regard to any otherwise
applicable vesting requirement under Section 6.3 hereof; provided, however, that
no such vesting shall occur if provision has been made in writing in connection
with such transaction for (a) the continuation of the Plan and/or the assumption
of such Options by a successor corporation (or a parent or subsidiary thereof)
or (b) the substitution for such Options of new options covering the stock of a
successor corporation (or a parent or subsidiary thereof), with appropriate
adjustments as to the number and kinds of shares and exercise prices. In the
event of any such continuation, assumption or substitution, the Plan and/or such
Options shall continue in the manner and under the terms so provided.

                  9. 2 Definition. For purposes of Section 9.1 hereof, a "change
in control" of the Company shall mean:

                  (i) an acquisition subsequent to the date hereof by any
         person, entity or group (within the meaning of Section 13(d)(3) or
         14(d)(2) of the Securities Exchange Act of 1934, as amended (the
         "Exchange Act")) (a "Person"), of beneficial ownership (within the
         meaning of Rule 13d-3 promulgated under the Exchange Act) of 30% or
         more of either (A) the then outstanding shares of Common Stock or (B)
         the combined voting power of the then outstanding voting securities of
         the Company entitled to vote generally in the election of directors
         (the "Outstanding Company Voting Securities"); excluding, however, the
         following: (1) any acquisition directly from the Company, other than an
         acquisition by virtue of the exercise of a conversion privilege unless
         the security being so converted was itself acquired directly from the
         Company, (2) any acquisition by the Company and (3) any acquisition by
         an employee benefit plan (or related trust) sponsored or maintained by
         the Company;

                  (ii) a change in the composition of the Board such that during
         any period of two consecutive years, individuals who at the beginning
         of such period constitute the Board, and any new director (other than a
         director designated by a person who has entered into an agreement with
         the Company to effect a transaction described in paragraphs (i), (iii)
         or (iv) of this section) whose election by the Board or nomination for
         election by the Company's stockholders was approved by a vote of at
         least two-thirds of the directors then still in office who either were
         directors at the beginning of the period or whose election or
         nomination for election was previously so approved, cease for any
         reason to constitute at least a majority of the members thereof;

<PAGE>   10
                  (iii) the approval by the stockholders of the Company of a
         merger, consolidation, reorganization or similar corporate transaction,
         whether or not the Company is the surviving corporation in such
         transaction, in which outstanding shares of Common Stock are converted
         into (A) shares of stock of another company, other than a conversion
         into shares of voting common stock of the successor corporation (or a
         holding company thereof) representing 80% of the voting power of all
         capital stock thereof outstanding immediately after the merger or
         consolidation or (B) other securities (of either the Company or another
         company) or cash or other property;

                  (v) the adoption by the Board of a resolution to the effect

Plan) for the shares of Common Stock purchased by exercise of an Option as soon
as practicable after due exercise and payment of the aggregate Option Price for
such shares. A separate stock certificate or separate stock certificates shall
be issued for any shares of Common Stock purchased pursuant to the exercise of
an Option that is an Incentive Stock Option, which certificate or certificates
shall not include any shares of Common Stock that were purchased pursuant to the
exercise of an Option that is a Nonqualified Stock Option.

                  10. 2 Conditions. The Company shall not be required to issue
or deliver any certificate for shares of Common Stock purchased upon the

         of such shares, under any federal or state law or under the rulings or

         governmental regulatory body, that the Committee shall in its sole
         discretion deem necessary or advisable;

<PAGE>   11
                  (ii) the obtaining of any approval or other clearance from any
         federal or state governmental agency which the Committee shall in its
         sole discretion determine to be necessary or advisable;

                  (iii) the lapse of such reasonable period of time following
         the exercise of the Option as the Committee from time to time may
         establish for reasons of administrative convenience;

                  (iv) satisfaction by the Optionee of all applicable
         withholding taxes or other withholding liabilities; and

                  (v) if required by the Committee, in its sole discretion, the
         receipt by the Company from an Optionee of (i) a representation in
         writing that the shares of Common Stock received upon exercise of an
         Option are being acquired for investment and not with a view to
         distribution and (ii) such other representations and warranties as are
         deemed necessary by counsel to the Company.

                  10. 3 Legends. The Company reserves the right to legend any
certificate for shares of Common Stock, conditioning sales of such shares upon
compliance with applicable federal and state securities laws and regulations.

                  11.2 Termination. The Plan shall terminate on the date
immediately preceding the tenth anniversary of the date the Plan is adopted by
the Board. The Board may, in its sole discretion and at any earlier date,
terminate the Plan. Notwithstanding the foregoing, no termination of the Plan
shall in any manner affect any Option theretofore granted without the consent of
the Optionee or the permitted transferee of the Option.

                  11.3 Amendment. The Board may at any time and from time to
time and in any respect, amend or modify the Plan. Solely to the extent deemed
necessary or advisable by the Board, for purposes of complying with Sections 422
or 162(m) of the Code or rules of any securities exchange or for any other
reason, the Board may seek the approval of any such amendment by the Company's
stockholders. Any such approval shall be by the affirmative votes of the
stockholders of the Company present, or represented, and entitled to vote at a

                                  MISCELLANEOUS

                  12. 1 Employment or other Service. Nothing in the Plan, in the
grant of any Option or in any Stock Option Agreement shall confer upon any
Eligible Person the right to continue in the capacity in which he is employed by
or otherwise provides services to the Company or any Subsidiary. Notwithstanding
anything contained in the Plan to the contrary, unless otherwise provided in a
Stock Option Agreement, no Option shall be affected by any change of duties or
position of the Optionee (including a transfer to or from the Company or any
Subsidiary), so long as such Optionee continues to be an Eligible Person.

                  12. 2 Rights as Shareholder. An Optionee or the permitted
transferee of an Option shall have no rights as a shareholder with respect to
any shares subject to such Option prior to the purchase of such shares by
exercise of such Option as provided herein. Nothing contained herein or in the
Stock Option Agreement relating to any Option shall create an obligation on the
part of the Company to repurchase any shares of Common Stock purchased
hereunder.

                  12. 3 Other Compensation and Benefit Plans. The adoption of
the Plan shall not affect any other stock option or incentive or other
compensation plans in effect for the Company or any Subsidiary, nor shall the
Plan preclude the Company from establishing any other forms of incentive or
other compensation for employees of the Company or any Subsidiary. The amount of
any compensation deemed to be received by an Optionee as a result of the
exercise of an Option or the sale of shares received upon such exercise shall
not constitute compensation with respect to which any other employee benefits of
such Optionee are determined, including, without limitation, benefits under any
bonus, pension, profit sharing, life insurance or salary continuation plan,
except as otherwise specifically determined by the Board or the Committee or
provided by the terms of such plan.

                  12. 4 Plan Binding on Successors. The Plan shall be binding
upon the Company, its successors and assigns, and the Optionee, his executor,
administrator and permitted transferees.

                  12. 5 Construction and Interpretation. Whenever used herein,
nouns in the singular shall include the plural, and the masculine pronoun shall
include the feminine

gender. Headings of Articles and Sections hereof are inserted for convenience
and reference and constitute no part of the Plan.

                  12. 6 Severability. If any provision of the Plan or any Stock
Option Agreement shall be determined to be illegal or unenforceable by any court
of law in any jurisdiction, the remaining provisions hereof and thereof shall be
severable and enforceable in accordance with their terms, and all provisions
shall remain enforceable in any other jurisdiction.

                  12. 7 Governing Law. The validity and construction of this
Plan and of the Stock Option Agreements shall be governed by the laws of the
State of Delaware.

                               SAGE NETWORKS, INC.

                     Incentive Stock Option Award Agreement

Award Agreement, dated as of March 10, 1999 (the "Date of Issuance"), between
Sage Networks, Inc., a Delaware corporation (the "Company"), and [MERGE FIELD 1]
(the "Optionee"), an employee of the Company. This Award Agreement is pursuant
to the terms of the Company's 1998 Stock Option Plan (the "Plan"). The
applicable terms of the Plan are incorporated herein by reference, including the
definition of terms contained in the Plan.

            WHEREAS, pursuant to the terms of the Asset Purchase Agreement,
dated as of March 8, 1999, among the Company, Sage Networks Acquisition Corp.,
a Delaware corporation, and Interliant, Inc., a Texas corporation (the "Asset
Purchase Agreement"), the option to purchase shares of Interliant common stock
(the "Interliant Option") granted to the Optionee is to be converted at the
Closing Date (as defined in the Asset Purchase Agreement) into an option to
purchase under the Plan shares of the common stock, $.01 par value, of the
Company (the "Common Stock") on the terms and subject to the conditions set
forth in this Award Agreement.

            Section 1. Stock Option Award. The Company grants to the Optionee,
on the terms and conditions hereinafter set forth, an Option with respect to
[MERGE FIELD 2] shares of the Common Stock (the "Option Shares"). The Option is
intended to qualify as an Incentive Stock Option under Section 422 of the Code.

            Section 2. Exercise Price. The exercise price per share of the
Option Shares shall be $0.13 per share.

            Section 3. Vesting of Stock Option [MERGE FIELD 3] of the Option
Shares shall be vested and exercisable on the Date of Issuance. [MERGE FIELD 4]
of the Option Shares shall become vested and exercisable upon the earlier of (i)
the first anniversary of the Closing Date provided that a Liquidity Event (as
defined in the Asset Purchase Agreement) has not taken place on or before such
date, or (ii) the date of a Liquidity Event provided the fair market value (as
defined in the Asset Purchase Agreement) of the aggregate issued and outstanding
shares of the Common Stock upon the occurrence of such Liquidity Event
(excluding the shares of Common Stock offered by the Company in connection with
the Liquidity Event) is less than $300,000,000. In the event such number of
Option Shares do not become vested on the earlier of such dates, the Option
shall lapse with respect to such number of Option Shares.

            Section 4. Incentive Stock Option Limitation. Pursuant to Section
7.2 of the Plan and Section 422(d) of the Code, to the extent the aggregate fair
market value of stock with respect to which the Option (together with any other
incentive stock options of the Company and its subsidiaries) is exercisable for
the first time by the Optionee during any calendar year exceeds $100,000, the
portion of the Option representing such excess shall not be treated as an
Incentive Stock Option and shall instead be treated as a Nonqualified Option
under the Plan.

<PAGE>   2

            Section 5. Option Term. Option Shares that become exercisable
pursuant to Section 3 hereof may be purchased at any time during the Option
Term. For purposes hereof, the "Option Term" shall commence on the Date of
Issuance and shall expire on the tenth anniversary of the Date of Grant, unless
earlier terminated upon the Optionee's termination from service as an employee
as provided in Section 6 hereof. For purposes hereof, the Date of Grant shall be
the date on which the Interliant Option was granted. Upon the expiration of the
Option Term, any unexercised Option Shares shall be cancelled and shall be of no
further force or effect.

            Section 6. Termination of Service. If Optionee's service as an
employee of the Company is terminated, the Optionee shall retain the right to
exercise any Option Shares until (i) in the event of a termination for any
reason other than death, "disability" or "retirement", the earlier of the
expiration of the Option Term or thirty (30) days after the date of such
termination of employment, (ii) in the event of a termination on account of
death, "disability" or "retirement", the earlier of the expiration of the Option
Term or three (3) months after such termination of employment; provided,
however, that in the event the Optionee's employment is terminated by the
Company for "cause", such Optionee's right to exercise any Option Shares shall
terminate as of 12:01 a.m. on the date of such termination of employment.

            For purposes of this Section 6: (i) "disability" shall mean the
Optionee being unable to engage in substantial gainful activity by reason of any
medically determinable physical or mental impairment that can be expected to
result in death or that has lasted or can be expected to last for a continuous
period of not less that one hundred eighty (180) days as determined by the board
of directors of the Company (the "Board"), with such determination to be final
and conclusive on all parties; (ii) "retirement" shall mean the termination of
employment or affiliation from the Company constituting retirement on or after
attaining age 65, as determined by the Board; and (iii) "cause" shall mean (A)
in the event that the Optionee is subject to any employment agreement or written
affiliation agreement between the Optionee and the Company, termination of
employment on account of the Optionee's breach of any such agreement that has
not been cured following thirty (30) days written notice (or the cure has not
been commenced and continued with reasonable diligence with a view to effecting
the cure within sixty (60) days of written notice), or (B) the Board determines
that such Optionee is being terminated because such Optionee admits, or is shown
to have committed, any fraud, dishonesty or act of willful misconduct in the
performance of the Optionee's duties to the Company.

            Section 7. Procedure for Exercise. The Option may be exercised, in
whole or part (for the purchase of whole shares only), by delivery of a written
notice (the "Notice") from the Optionee to the Secretary of the Company at the
Company's principal office, which Notice shall: (i) state the number of Option
Shares being exercised; (ii) include any representation of the Optionee required
pursuant to Section 9 hereof; (iii) in the event that the Option shall be
exercised by any person other than the Optionee pursuant to Section 12 hereof,
include appropriate proof of the right of such person to exercise the Option;
and (iv)

comply with such further requirements consistent with the Plan as the Committee
may from time to time prescribe. In addition, as a condition to exercise all or
any part of the Option, the Optionee must execute and deliver to the Company a
Shareholders Agreement in the form attached hereto as Exhibit A.

            Section 8. Payment of Exercise Price and Tax Withholding. Payment of
the exercise price for the Option Shares shall be made in cash or by cashier's
check, certified check or postal or express money order. In addition and at the
time of exercise, as a condition of delivery of the Option Shares, the Optionee
shall remit to the Company all required federal, state and local withholding tax
amounts in any manner permitted for the payment of the exercise price as
provided above.

            Section 9. Investment Representation. Upon the exercise of the
Option at a time when there is not in effect a registration statement under the
Securities Act of 1933 relating to the Option Shares, the Optionee hereby
represents and warrants, and by virtue of such exercise shall be deemed to
represent and warrant, to the Company that the Option Shares shall be acquired
for investment and not with a view to the distribution thereof, and not with any
present intention of distributing the same, and the Optionee shall provide the
Company with such further representations and warranties as the Company may
require in order to ensure compliance with applicable federal and state
securities, blue sky and other laws. No Option Shares shall be purchased upon
the exercise of the Option unless and until the Company and/or the Optionee
shall have complied with all applicable federal or state registration, listing
and/or qualification requirements and all other requirements of law or of any
regulatory agencies having jurisdiction, unless the Committee has received
evidence satisfactory to it that a prospective Optionee may acquire such shares
pursuant to an exemption from registration under the applicable securities laws.
Any determination in this connection by the Committee shall be final, binding,
and conclusive. The Company reserves the right to legend any certificate for
shares of Common Stock, conditioning sales of such shares upon compliance with
applicable federal and state securities laws and regulations.

            Section 10. No Rights as Stockholder or Employee.

            (a) The Optionee shall not have any privileges of a stockholder of
the Company with respect to any Option Shares subject to (but not acquired upon
valid exercise of) the Option, nor shall the Company have any obligation to
issue any dividends or otherwise afford any rights to which shares of Common
Stock are entitled with respect to any such Option Shares, until the date of the
issuance to the Optionee of a stock certificate evidencing such shares.

            (b) Nothing in this Award Agreement or the Option shall confer upon
the Optionee any right to continue as an employee of the Company or to interfere
in any way with the right of the Company to terminate the Optionee's employment
at any time.


                                       3
<PAGE>   4

            Section 11. Adjustments. If at any time while the Option is
outstanding, the number of outstanding shares of Common Stock is changed by
reason of a reorganization, recapitalization, stock split or any of the other
events described in Section 5.2 of the Plan, the number and kind of Option
Shares and/or the exercise price of such Option Shares shall be adjusted in
accordance with the provisions of Section 5.2 of the Plan.

            Section 12. Restriction on Transfer of Option. The Option may not be
transferred, pledged, assigned, hypothecated or otherwise disposed of in any way
by the Optionee, except by will or by the laws of descent and distribution. In
the event an Optionee becomes legally incapacitated, his Option shall be
exercisable by his legal guardian, committee or legal representative. If the
Optionee dies, the Option shall thereafter be exercisable by the Optionee's
executors or administrators. The Option shall not be subject to execution,
attachment or similar process. Any attempted assignment, transfer, pledge,
hypothecation or other disposition of the Option contrary to the provisions
hereof, and the levy of any execution, attachment or similar process upon the
Option, shall be null and void and without effect.

            Section 13. Lock-Up Agreement. As a condition to the grant of the
Option, Optionee agrees to execute and deliver to the underwriters in connection
with the Company's initial public offering, a lock-up agreement in customary
form, restricting the transfer by the Optionee of shares of the Common Stock and
Options for a period of not more that 180 days following the closing of such
initial public offering.

            Section 14. Notices. Any notice hereunder by the Optionee shall be
given to the Company in writing and such notice shall be deemed duly given only
upon receipt thereof at the Company's office at [11 Martine Avenue, White
Plains, NY 106063, Attention General Counsel], or at such other address as the
Company may designate by notice to the Optionee. Any notice hereunder by the
Company shall be given to the Optionee in writing and such notice shall be
deemed duly given only upon receipt thereof at such address as the Optionee may
have on file with the Company.

            Section 15. Construction. The construction of this Award Agreement
is vested in the Committee, and the Committee's construction shall be final and
conclusive.

            Section 16. Governing Law. This Award Agreement shall be construed
and enforced in accordance with the laws of the State of Delaware, without
giving effect to the choice of law principles thereof.

            Section 17. Entire Agreement. This Award Agreement and the Plan
constitute the entire agreement between the parties with respect to the subject
matter hereof and thereof and supersede all prior written or oral negotiations,
commitments, representations and agreements with respect thereto and the
Optionee agrees that, as of the Closing Date, the Interliant Option shall be
superceded and shall be of no further force or effect, and the Optionee shall
have no further rights in connection therewith.

                               SAGE NETWORKS, INC.

                    Nonqualified Stock Option Award Agreement

Award Agreement, dated as of March 10, 1999 (the "Date of Issuance"), between
Sage Networks, Inc., a Delaware corporation (the "Company"), and FIELD_1 (the
"Optionee"), an employee of the Company or a subsidiary of the Company. This
Award Agreement is pursuant to the terms of the Company's 1998 Stock Option Plan
(the "Plan"). The applicable terms of the Plan are incorporated herein by
reference, including the definition of terms contained in the Plan.

            WHEREAS, pursuant to the terms of the Asset Purchase Agreement,
dated as of March 8, 1999, among the Company, Sage Networks Acquisition Corp., a
Delaware corporation, and Interliant, Inc., a Texas corporation (the "Asset
Purchase Agreement"), the option to purchase shares of Interliant common stock
(the "Interliant Option") granted to the Optionee is to be converted at the
Closing Date (as defined in the Asset Purchase Agreement) into an option to
purchase under the Plan shares of the common stock, $.01 par value, of the
Company (the "Common Stock") on the terms and subject to the conditions set
forth in this Award Agreement.

            Section 1. Stock Option Award. The Company grants to the Optionee,
on the terms and conditions hereinafter set forth, an Option with respect to
FIELD_2 shares of the Common Stock (the "Option Shares"). The Option is not
intended to qualify as an Incentive Stock Option under Section 422 of the Code.

            Section 2. Exercise Price. The exercise price per share of the
Option Shares shall be $0.13 per share.

            Section 3. Vesting of Stock Option. FIELD_3 of the Option Shares
shall be vested and exercisable on the Date of Issuance. If the "Fair Market
Value" (as defined in the Asset Purchase Agreement) of the aggregate issued and
outstanding shares of the Common Stock of the Company determined on the date of
the occurrence of a Liquidity Event (as defined in the Asset Purchase Agreement)
(excluding the shares of Common Stock of the Company issued by the Company in
connection with the Liquidity Event, if any) is less than $300,000,000 and the
Company consummates the Liquidity Event, additional Option Shares shall become
vested and exercisable on the date of occurrence of the Liquidity Event such
that the aggregate of the Optionee's vested and exercisable Option Shares on
such date equals FIELD_4 of the vested and exercisable Total Option Shares with
such result rounded down to the nearest whole number of shares. For purposes
hereof, Total Option Shares shall mean such number of shares of Common Stock
subject to options delivered or deliverable to all Optionees who receive option
grants on the Date of Issuance such that the aggregate value of such shares is
equal to $13,023,778 (determined at the Fair Market Value (as defined in the
Asset Purchase Agreement) of such shares on the date of the Liquidity Event) but
in no event shall the Total Option Shares be more than 2,322,139. If a Liquidity
Event does not occur on or before the first anniversary of the Closing Date, all
of the Option Shares shall be vested and exercisable on such anniversary date.
The Option

vested and exercisable in accordance with the provisions of this Section 3.

            Section 4. Option Term. Option Shares that become exercisable
pursuant to Section 3 hereof may be purchased at any time during the Option
Term. For purposes hereof, the "Option Term" shall commence on the Date of

earlier terminated upon the Optionee's termination from service as an employee
as provided in Section 5 hereof. For purposes hereof, the Date of Grant shall be
the date on which the Interliant Option was granted. Upon the expiration of the
Option Term, any unexercised Option Shares shall be cancelled and shall be of no
further force or effect.

            Section 5. Termination of Service. If Optionee's service as an

event of a termination for any reason other than death, "disability" or
"retirement", the earlier of the expiration of the Option Term or thirty (30)
days after the date of such termination of employment, (ii) in the event of a
termination on account of death, "disability" or "retirement", the earlier of
the expiration of the Option Term or three (3) months after such termination of
employment; provided, however, that in the event the Optionee's employment is
terminated by the Company or a subsidiary of the Company, as applicable, for
"cause", such Optionee's right to exercise any Option Shares shall terminate as
of 12:01 a.m. on the date of such termination of employment.

            For purposes of this Section 5: (i) "disability" shall mean the
Optionee being unable to engage in substantial gainful activity by reason of any
medically determinable physical or mental impairment that can be expected to
result in death or that has lasted or can be expected to last for a continuous
period of not less that one hundred eighty (180) days as determined by the board
of directors of the Company (the "Board"), with such determination to be final
and conclusive on all parties; (ii) "retirement" shall mean the termination of
employment or affiliation from the Company or a subsidiary of the Company, as
applicable, constituting retirement on or after attaining age 65, as determined
by the Board; and (iii) "cause" shall mean (A) in the event that the Optionee is
subject to any employment agreement or written affiliation agreement between the
Optionee and the Company or a subsidiary of the Company, as applicable,
termination of employment on account of the Optionee's breach of any such
agreement that has not been cured following thirty (30) days written notice (or
the cure has not been commenced and continued with reasonable diligence with a
view to effecting the cure within sixty (60) days of written notice), or (B) the
Board determines that such Optionee is being terminated because such Optionee
admits, or is shown to have committed, any fraud, dishonesty or act of willful
misconduct in the performance of the Optionee's duties to the Company or a
subsidiary of the Company, as applicable.

Any determination in this connection by the Committee shall be final, binding,
and conclusive. The Company reserves the right to legend any certificate for

                              EMPLOYMENT AGREEMENT


         This Agreement made and entered into as of the 1st day of January,
1999, by and between SAGE NETWORKS, INC., a Delaware corporation, having a place
of business at 215 First Street, Cambridge, MA 02142 ("Employer"), and, Leonard
J. Fassler, having an address at 7 Old Woods Drive, Harrison, NY 10528
("Employee").


                                   WITNESSETH:


         WHEREAS, Employer is engaged in the Internet Web hosting and related
services business; and

         WHEREAS, Employer desires to employ Employee as Co-Chairman of
Employer, and Employee desires to be so employed by Employer, all pursuant to
the terms and conditions hereinafter set forth.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
promises and covenants herein contained, it is agreed as follows:


         1.       EMPLOYMENT:  DUTIES

                  (a) Employer hereby agrees to employ Employee, and Employee
hereby agrees to accept employment during the term hereof as Co-Chairman of
Employer, and shall perform such services as are customarily performed by
persons holding such offices and shall be subject at all times to the direction
of the Board of Directors of Employer. Nothing herein contained shall be
construed as, including, but not limited to (i) preventing Employee from
devoting a portion of his business time to other business ventures of Employee
or preventing Employee from investing his personal assets in any business,
provided such business venture or business does not compete with Employer or
conflict with Employee's duties and obligations as an officer and director of
the Employer, or (ii) preventing Employee from purchasing securities in any
corporation whose securities are regularly publicly traded, if such purchases
shall not result in his owning beneficially at any time 5% or more of the equity
securities of any corporation engaged in a business which is competitive to that
of Employer.

         2.       TERM

                  Employee's employment hereunder shall be for a term commencing
January 1, 1999 and ending on December 31, 1999. The Agreement shall be
automatically extended from year to year thereafter unless either party gives
not less than three (3) months prior written notice to the other that such party
elects to have the Agreement terminated effective at the end of the initial or
then current renewal term.
<PAGE>   2
         3.       COMPENSATION

         (a) As compensation for the performance of his duties on behalf of
Employer, Employer shall pay Employee a salary at the rate of One Hundred Eighty
Thousand Dollars ($180,000.00) per annum, payable in installments in accordance
with the usual practice of the Employer.

         (b) Employer shall reimburse Employee for the expenses incurred by
Employee in connection with his duties hereunder upon presentation by Employee
of the details of vouchers for such expenses in accordance with customary
Employer practice.

         (c) Employee shall be entitled to participate in all retirement, life
insurance, medical insurance, disability insurance, vacation, savings and other
employee benefit plans generally available to the senior officers of the
Company, so long as such benefits comply with applicable law (including without
limitation the Internal Revenue Code of 1986, as amended, and ERISA).


         4.       NON-COMPETITION

         (a) During the term of this Agreement and for a period of twenty-four
(24) months from the date of termination of his employment hereunder for
whatever reason, Employee agrees that he will not solicit any customers who are
presently or may hereafter become customers of Employer unless such solicitation
is entirely unrelated to Employer's business, or compete in any way with
Employer alone or together with others in which Employer is engaged in business
at the time of termination of employment.

         (b) Subsequent to the expiration or termination of this Agreement,
Employee will not interfere with or disrupt or attempt to disrupt Employer's
business relationship with its customers or suppliers or solicit the employees
or Employer.

         (c) During the term of this Agreement and for a period of twenty-four
(24) months from the date of termination of his employment hereunder for
whatever reason, Employee will not disclose or use or enable anyone else to use
any information or data which may be obtained by him or available to him during
the term of employment.

         (d) In the event that Employee breaches any provisions of this
paragraph or there is a threatened breach, then, in addition to any other rights
which Employer may have, Employer shall be entitled to injunctive relief to
enforce the restrictions contained herein. In the event that an actual
proceeding is brought in equity 


                                       2
<PAGE>   3
to enforce the provisions of this paragraph, Employee shall not urge as a
defense that there is an adequate remedy at law nor shall Employer be prevented
from seeking any other remedies which may be available.

         (e) The existence of any claim or cause of action by Employee against
Employer, whether predicated upon this Agreement or otherwise, shall not
constitute a defense to the enforcement by Employer of the foregoing restrictive
covenants but shall be litigated separately.


         5.       TERMINATION

         (a) Anything to the contrary notwithstanding, this Agreement shall
terminate 30 days after the Employee's (i) death or (ii) disability for a period
of not less than twenty-six consecutive weeks; provided, however, that the
provisions of Section 6 hereof shall remain in full force and effect through the
end of the term hereof.

         (b) Employee's employment hereunder may also be terminated by the
Employer before the expiration of the term hereof only for cause as herein
defined. "Cause" shall mean only one or both of the following occurrences:


                  (i) The Employee's conviction of a felony by a court of
         competent jurisdiction (which conviction, through lapse of time or
         otherwise, is not subject to appeal); or

                 (ii) The Employee's commission of an act of fraud or 
         embezzlement upon the Employer.


         6.       SEVERANCE

                  In the event of termination of employment of Employee by
Employer before the expiration of the term hereof, except when such termination
is in accordance with the provisions of paragraph 5(a) or 5(b) hereof, Employer
will provide Employee with severance pay in an amount equal to Employee's base
annual salary through the end of the term hereof, which shall be payable in a
lump sum, discounted based on the prime rate of Chase Bank then in effect, which
lump sum shall be payable within 30 days of the date of termination. Employer
shall also continue to provide to Employee the retirement benefits, life
insurance, medical insurance and disability insurance pursuant to Section 3(d)
through the end of the term hereof.

                  In the event of termination of employment of Employee before
the expiration of the term hereof pursuant to the provisions of paragraph 5(a)
hereof, Employer will: (i) provide Employee (or Employee's estate) with
severance pay in an 



                                       3

amount equal to one year's base annual salary, which shall be payable in a lump
sum, discounted based on the prime rate of Chase Bank then in effect, which lump
sum shall be payable within 30 days of the date of termination; (ii) continue to
provide to Employee the retirement benefits, life insurance, medical insurance
and disability insurance pursuant to Section 3(d) through the end of the term
hereof; and (iii) continue to provide Employee's spouse and minor children with
medical benefits pursuant to Section 3(d) through the end of the term hereof.

                  8. SEVERABILITY OF PROVISIONS

                  If any provision of this Agreement shall be declared by a
court of competent jurisdiction to be invalid, illegal or incapable of being
enforced in whole or in part, the remaining conditions and provisions or
portions thereof shall nevertheless remain in full force and effect and
enforceable to the extent they are valid, legal and enforceable, and no
provision shall be deemed dependent upon any other covenant or provision unless
so expressed herein.


                  9. GOVERNING LAW

                  This Agreement shall be construed and governed by the laws of
the State of New York.


                  10. NON-WAIVER

                  The failure of either party to insist upon the strict
performance of any term or condition in this Agreement shall not be considered a
waiver or relinquishment of future compliance therewith.


                  11. ENTIRE AGREEMENT; MODIFICATION

his or its duties under this Agreement without the prior written consent of the
other party; provided, however, that (i) this Agreement shall inure to the
benefit of and be binding upon the successors and assigns of the Employer upon

      3. Duties.

            The Employee shall exercise such powers and perform such duties and

his entire business time, energy and attention to the business of the Employer,
or its subsidiaries. The Employee shall be the Executive Vice President of the
Employer and President of Interliant of Texas, Inc., a Delaware corporation and
a wholly owned subsidiary of Employer. The Employee shall report to the Chief

      4. Non-Competition; Nonsolicitation; Confidentiality; Intellectual
         Property Matters.

the Agreement Term or as of the date of termination, as the case may be, that is
located or does business in any state in the United States or anywhere
throughout the world except as an officer, director, shareholder or employee of
the Employer or any affiliate thereof. However, nothing in this Section 4 shall
prohibit the Employee from acquiring or holding any issue of stock or securities
of any person that has any securities registered under Section 12 of the
Securities Exchange Act of 1934, as amended, listed on a national securities
exchange or quoted on the automated quotation system of the National Association
of Securities Dealers, Inc. so long as (i) the Employee is not deemed to be an
"affiliate" of such person as such term is used in paragraphs (c) and (d) of
Rule 145 under the Securities Act of 1933, as amended, and (ii) the Employee
and/or members of his immediate family or persons under his control do not own
or hold more than 5% of any voting securities of any such person.

            (b) During the Agreement Term and for the Restricted Period, the
Employee will not, unless acting with the express written consent of Employer,
directly or indirectly, solicit or interfere with, or endeavor to entice away:

                  (i) any person who has rendered services as an employee for
                  the Company with respect to the Business or the Employer or
                  any of their respective affiliates during the 12 month period
                  immediately preceding the date of termination or expiration of
                  this Agreement; or

                  (ii) with respect to any business substantially similar to the
                  business in which the Employer or any of its affiliates is or
                  has been engaged on or after the date of this Agreement, any
                  person or entity who was a customer or client of the Employer,
                  the Company or any of their respective affiliates at any point
                  during the 12 months preceding the termination or expiration
                  of this Agreement or any person or entity who requested or
                  received a proposal from the Employer, the Company or any of
                  their respective affiliates within the 12 months preceding the
                  termination or expiration of this Agreement.

            (c) During the Agreement Term and at all times thereafter the
Employee agrees to hold in confidence all matters and things related to the
business of the Employer and each of its direct and indirect subsidiaries or
affiliates of a confidential or secret nature (including, without limitation,
all private or proprietary information) which the Employee may acquire, learn,
develop or create during the Agreement Term and will not, without the written
consent of Employer, except in the performance of the Employee's duties as an
employee of the Employer, use, publish or disclose any such matter or thing
except to the extent that (i) such information is otherwise publicly available
or (ii) disclosure is required by applicable law, regulation, legal process or
court order or (iii) such information is otherwise lawfully obtained by the
Employee.

            (d) The Employee hereby assigns, and agrees to assign, to the
Employer all of the Employee's right, title and interest in and to all
inventions, discoveries, improvements, ideas, computer or other apparatus
programs and related documentation, and other works of authorship, whether or
not patentable, copyrightable or subject to other forms of protection, that are
made, created, developed, written or conceived by the Employee during the
Agreement Term (and any written or oral extension thereof), whether during or
outside of regular work hours, either solely or jointly with another, in whole
or in part, either (i) in the course of the Employee's employment by the
Employer or its affiliates and on behalf of the Employer as part of the
Employee's duties or (ii) relating to the actual or anticipated business or
research or development of the Employer, or, (iii) in either of both instances
described in the foregoing clauses "(i)" or "(ii)," with the use of the
Employer's time, material, private or proprietary information, or facilities
(herein each designated "Intellectual Property"). Notwithstanding the foregoing,
it is understood and agreed between the Employer and the Employee that, from
time to time, the Employee has engaged in writing and speaking activities that
are not related to his duties to the Employer hereunder, and that the Employee
shall be permitted to continue to engage in such activities and shall be
permitted to do so during regular work hours and with the use of the Employer's
facilities (but no private or proprietary information of the Employer), so long
as these activities do not materially interfere with the performance by the
Employee of his duties hereunder. The Employee agrees to execute (without charge
to the Employer) a specific assignment of title to Employer and to do anything
else reasonably necessary to enable Employer to secure a patent, copyright or
other form of protection for said Intellectual Property anywhere in the world.
The Employee acknowledges and agrees that the copyrights in Intellectual
Property created within the scope of the Employee's employment belong to the
Employer by operation of law.

            (e) The Employee agrees to execute upon request by the Employer from
time to time during the Agreement Term, any nondisclosure, intellectual property
or confidentiality agreements which the Employer may require its employees
generally to execute, consistent with the foregoing and paragraph (d) above, but
not inconsistent with other terms of this Agreement.

      5. Salary; Bonuses.

            (a) As compensation for the Employee's services to be rendered to
the Employer and in consideration for the covenants and agreements of the
Employee contained herein, the Employer shall pay to the Employee an annual Base
Salary of $180,000.


                                       4
<PAGE>   5

            (b) The Base Salary shall be payable in substantially equal
installments and in substantially the same manner that salaries are paid by the
Employer to other employees in comparable positions with the Employer. The Board
(or a committee of the Board) shall make an annual review of the Base Salary and
may, but shall not be obligated to, in its sole discretion, make increases
thereto.

            (c) The Employer shall pay to the Employee a signing bonus (the
"Signing Bonus"). The Signing Bonus shall be equal to $150,000, two-thirds
(i.e., $100,000) of which shall be payable upon execution and delivery of this
Agreement by the parties hereto. The remaining one-third (i.e., $50,000) shall
be payable on the first anniversary of the date of this Agreement, provided that
this Agreement has not been terminated by the Employer for Cause or by the
Employee without Good Reason on or before the date that such installment is
payable.

            (d) The Employer shall pay to the Employee an objectives-based bonus
(the "Objective-Based Bonus"). The Objective Based-Bonus shall be equal to
$70,000 per year and shall be paid to Employee upon Employee meeting or
exceeding certain objectives as determined in good faith by the Chief Executive
Officer of Employer in consultation with Employee.

      6. Vacation.

            The Employee shall be entitled to vacation periods annually during
the Employee's employment under this Agreement consistent with the Employer's
vacation policy for employees generally.

      7. Reimbursement for Expenses.

            The Employer shall reimburse the Employee for all reasonable and
necessary expenses and other disbursements actually incurred by the Employee for
and on behalf of the Employer in the performance of the Employee's duties upon
submission of adequate documentation of such expenses and in accordance with the
Company's reimbursement policy then in effect.

      8. Benefits.

            The Employee shall be entitled to participate in any health, medical
and dental, insurance or similar plan or program of the Employer established or
in effect for the benefit of its employees generally (collectively, "Insurance
Benefits").

      9. Termination By Employer for Cause.

            Termination of this Agreement for "Cause" by the Employer shall mean
termination due to the occurrence of any of the following events:

      (a) if the Employee is convicted of any crime (whether or not involving
the Employer) which constitutes a felony or involves moral turpitude, fraud or
misrepresentation;


                                       5
<PAGE>   6

      (b) if the Employee engages in dishonest conduct in connection with the
Employee's employment, which is fraud, theft or misappropriation or embezzlement
of Employer's funds, which termination shall be effective on the tenth (10th)
day after written notice from Employer is delivered to the Employee and Employee
shall have had a reasonable opportunity to be heard by the Chairman or
Co-Chairman of the Employer;

      (c) if the Employee shall have breached any of the Employee's material
obligations under this Agreement, (other than an inadvertent breach as to which
the Employee shall have discontinued the activity causing the breach within two
(2) business days following delivery of notice thereof to the Employee); or

      (d) if the Employee has habitually failed to follow the reasonable
directives of the Employer for the performance of the Employee's duties or
responsibilities hereunder (other than any failure resulting from the Employee's
incapacity due to physical or mental illness), including, without limitation,
the Employee's duties and responsibilities under Section 3 hereof, after due
notice to the Employee, and a reasonable opportunity to be heard by the Chairman
or Co-Chairman of the Employer within one month after the giving of such notice
and to correct such failure.

      10. Certain Remedies.

            (a) In the event the Employer terminates this Agreement for Cause as
defined in Section 9 above, all of the Employee's rights under this Agreement
shall thereupon terminate and Employee shall be entitled only to all accrued and
unpaid portions of the Base Salary through the date of such termination, and to
all vested benefits under any employee benefit plans maintained by the Employer,
whether funded or unfunded, accrued through the date of such termination.
Notwithstanding the foregoing, such termination shall be without prejudice to
any right the Employee may have to continue to participate, on a post-employment
basis, in any retirement plan of the Employer now existing or established
hereafter for the benefit of its employees in general or any health plan of the
Employer, to the extent the Employee is eligible under the general provisions
thereof or as required by applicable law, including, without limitation, COBRA.

            (b) In the event of termination by the Employer without Cause or in
the event the Contract Termination Date occurs on account of the Board or an
officer of Employer at the direction of the Board, giving the notice provided
for in Section 2(a) hereof or the Employee terminates this Agreement for Good
Reason, the Employer shall pay to the Employee (i) any remaining amount of the
Signing Bonus, plus (ii) the greater of (A) the amount of remaining Base Salary
and other compensation due to the Employee under the terms of this Agreement
(including, without limitation, a pro rata portion of the Objective-Based Bonus
earned during the year in which Employee's employment is terminated for the
portion of the year that the Employee was employed by the Employer), as in
effect at such time, and (B) an amount equal to six (6) months of his monthly
Base Salary in effect at the Date of Termination or the Contract Termination
Date, as the case may be, plus a pro rata portion of the Objective-Based Bonus
earned during the year in which Employee's employment is terminated for the
portion of the year that the Employee was employed by the Employer during the
year of such termination, and the Employee's participation in all customary
benefit programs established by the Employer shall 


                                       6
<PAGE>   7

continue as before termination during the longer of the remainder of the
Agreement Term and such six-month period, as if he continued to be employed by
the Employer during such period. In the event any such benefit program is by law
not available to non-employees, the Employer will provide a comparable benefit
to the Employee during such period. The date on which a termination pursuant to
this Section 10(b) becomes effective (the "Date of Termination") shall be the
date on which the party terminating this Agreement gives the other party written
notice of termination in accordance with the terms hereof.

      11. No Mitigation

            The provisions of this Agreement are not intended to, nor shall they
be construed to require that, the Employee mitigate the amount of any payment
provided for in this Agreement by seeking or accepting other employment. Without
limiting the foregoing, the Employer's obligations to make the payments to the
Employee under this Agreement and otherwise perform its obligations hereunder
shall not be affected by any right of set-off that the Employer may have against
the Employee.

      12. Notice.

            Any notice required or permitted to be given hereunder shall be in
writing and shall be deemed to have been duly given if delivered or mailed by
registered mail, postage prepaid: if to the Employee at the Employee's address
set forth on the first page hereof, or at such other address as Employee shall
designate by notice to the Employer, and if to the Employer at 215 First Street,
Cambridge, MA 02142, with a copy to Bruce S. Klein, Senior Vice President and
General Counsel, Sage Networks, Inc., 11 Martine Avenue, 12th Floor, White
Plains, NY 10606, or at such other address as it shall designate by notice to
the Employee.

      13. Successors and Assigns.

            This Agreement is personal in its nature and neither of the parties
hereto shall, without the consent of the other, assign or transfer this
Agreement or any rights or obligations hereunder, except that Employer may
assign this Agreement to any successor entity resulting from a merger,
consolidation, sale of stock of Employer or sale of substantially all of the
assets of Employer, provided that such successor entity expressly assumes all
the the obligations of the Employer under this Agreement. This Agreement shall
inure to the benefit of and be enforceable by the Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees. If the Employee should die while any amount would still
be payable to him hereunder if he had continued to live, all such amounts,
unless otherwise provided herein, shall be paid in accordance with the terms of
this Agreement to the Employee's devisee, legatee or other designee or, if there
is no such designee, to the Employee's estate.

      14. Governing Law; Jurisdiction.


                                       7
<PAGE>   8

            This Agreement shall be governed by and construed and enforced in
accordance with the laws of the State of New York without regard to its conflict
of law rules. The Employer and the Employee submit and consent to the exclusive
jurisdiction of the state and federal courts located in the State of New York,
Counties of New York or Westchester with respect to any legal actions between
them relating to this Agreement.

      15. Only Contract Relating to Employment; Amendments.

            This Agreement supersedes any prior contracts relating to employment
between the Employee and the Employer and constitutes the full and complete
agreement between the Employee and the Employer in such respect and no
statement, representation, warranty or covenant has been made by either party
with respect thereto except as expressly set forth herein. This Agreement cannot
be changed, modified or amended and no provision or requirement hereof may be
waived without the consent in writing of the Employee and the Employer.

      16. Headings.

            The headings in this Agreement are for convenience of reference only
and shall not control or affect the meaning or construction of this Agreement.

      17. Severability.

            The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect. If any provision
contained in this Agreement is found to be unenforceable by reason of the
extent, duration or scope thereof, or otherwise, then the court making such
determination shall have the right to reduce such extent, duration, scope or
other provision so that in its reduced form any such restriction shall
thereafter be enforceable to the maximum extent permitted by law. It is the
intent of the parties hereto that the covenants contained in this Agreement
shall be enforced to the fullest extent permissible under the laws and public
policies of each jurisdiction in which enforcement is sought (the Employee
hereby acknowledging that said restrictions are reasonably necessary for the
protection of the Employer).

      18. Counterparts.

            This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original but all of which together shall constitute one
and the same instrument.

            IN WITNESS WHEREOF, the Employer and the Employee have caused this
Agreement to be executed as of the date first above written.

                                  DEED OF LEASE


              THIS DEED OF LEASE ("Lease") is made as of the 11th day of
     February, 1999, by and between WESTWOOD CENTER, L.L.C., a Delaware limited
     liability company ("Landlord"), and SAGE NETWORKS, INC., a Delaware
     corporation ("Tenant").

                                R E C I T A L S:

              Landlord, for and in consideration of the rents and all other
     charges and payments hereunder and of the covenants, agreements, terms,
     provisions and conditions to be kept and performed hereunder by Tenant,
     grants and conveys to Tenant, and Tenant hereby hires and takes from
     Landlord, a leasehold interest in the premises described below
     ("Premises"), subject to all matters hereinafter set forth and upon and
     subject to the covenants, agreements, terms, provisions and conditions of
     this Lease for the term hereinafter stated.

              NOW THEREFORE Landlord and Tenant hereby agree to the following:

I.       TERMS.

         A. Premises. (a) The premises demised by this Lease will consist of
approximately 13,171 rentable square feet of space (the "Premises") measured by
Landlord's architect in accordance with the 1989 Washington, D.C. Commercial
Association of Realtors ("WDCAR") Standard Method of Measurement, and shall be
comprised of suite _____ on the first floor in that building located at 8619
Westwood Center Drive, McLean, Fairfax County, Virginia (the "Building"),
together with the right to the use of not more than forty nine (49) parking
spaces located in the adjacent parking facility (including any parking structure
and/or surface lot as may exist for the Building from time to time), and the
non-exclusive use of various Common Areas (as defined in Section 39 hereof), as
more particularly set forth herein. The land upon which the Building is
situated, which is generally depicted on the diagram attached hereto as Exhibit
B (the "Site Plan") and incorporated herein by reference, shall be referred to
hereinafter as the "Land". The Land and the Building are collectively referred
to herein as the "Project". The location and dimensions of the Premises are
shown on the conceptual floor plans attached hereto as Exhibit A and
incorporated herein by reference. No easement for light or air is incorporated
in or intended to be conveyed with the Premises.

         (b) Upon completion of the final plans and specifications for the
Premises, Landlord shall deliver to Tenant a certificate indicating the total
square footage of the Premises based upon an opinion of a registered architect.
Tenant, or its representatives, shall have the right to access, review and
remeasure the Premises; provided, however, Tenant shall give notice exercising
such right within fifteen (15) days after receipt of the Landlord's notice or
Tenant shall be deemed to have waived that right. If Tenant's remeasurement
discloses a 
<PAGE>   6
discrepancy of more than one and one-half percent (1-1/2%), then the Lease shall
be adjusted in accordance with such remeasurement unless Landlord disputes the
results of Tenant's remeasurement, in which event, prior to the remeasurement
being considered effective, the question of such measurement shall be submitted
to Arbitration in accordance with Section 49 hereof, (provided that in such
event the initial two arbitrators shall be each of Landlord's and Tenants
architects, the third arbitrator must also be a licensed architect), and rather
than the determination of the third arbitrator being binding, the square footage
of the Premises shall be deemed to be the average of the determinations of those
two architects whose determinations are the closest, with the third to be
disregarded. If the remeasurement (or, if disputed, Arbitration) establishes
that there was a discrepancy adverse to Tenant of more than three percent (3%)
or more, then Landlord shall reimburse Tenant for the reasonable and actual cost
of remeasurement and of any Arbitration within thirty (30) days after invoice
therefor, and if the remeasurement establishes that there was a discrepancy of
less than three percent (3%), then Tenant shall reimburse Landlord for the
reasonable Arbitration expenses within thirty (30) days after invoice therefor.
The foregoing shall not affect the Commencement Date of this Lease, and pending
resolution pursuant hereto, Base Rent paid hereunder shall be based upon the
estimate set forth above. Further the foregoing measurement (i) shall only be
available as of substantial completion and not thereafter, and (ii) shall cause
adjustment in the amount of the Allowance (as defined in Exhibit C) and in
Tenant's Share.

         B. Tenant's Share. "Tenant's Share" shall mean a fraction, the
numerator of which is the total rentable square footage of the Premises as
determined in accordance with Section 1.1 hereof, and the denominator of which
is 97,081, representing the total rentable square footage of the Building. No
adjustment shall be made for space within the Project occupied by any building
engineer(s) or similar on-site property management or operational personnel,
provided any such space will be located within a core area location to be
determined within the reasonable judgment of Landlord.

         C. Lease Term. The term of this Lease (the "Term" or "Lease Term")
shall commence on the "Commencement Date" as defined in Section 1.4 below (and
as more fully set forth in Exhibit C hereto), and shall expire one hundred
twenty (120) months after the Commencement Date (the "Lease Expiration Date");
provided that if the Commencement Date is a date other than the first day of a
calendar month, the Lease Term shall run for the number of months set forth
above from the first day of the calendar month following the Commencement Date.

         D. Commencement Date.

                  1. The "Commencement Date" shall be ninety (90) days after the
date upon which Landlord delivers the Notice of Possession (as defined in
Exhibit C attached hereto) to Tenant, and Tenant is able to enter the Premises
for the purposes of performing Tenant's Work therein as identified in Exhibit C
attached hereto. Notwithstanding the foregoing, for purposes of this Lease, the
term "Commencement Date" shall also mean any adjusted Commencement Date which
may be established pursuant to the provisions of this
<PAGE>   7
Lease. Landlord and Tenant hereby agree to execute a Declaration, in the form
attached hereto as Exhibit E, to confirm the Commencement Date. Tenant's failure
to execute said Declaration shall not affect the Commencement Date, or the Lease
Expiration Date, as the same may be determined by the terms of this Lease.

         E. Base Rent. The base rent payable by Tenant hereunder ("Base Rent")
is set forth in this Section 1.5.1, below. The Base Rent payable to Landlord is
in addition to (and not to be reduced by) any payment of Additional Rent (as
hereinafter defined) hereunder. Base Rent is "net" of electrical service which
will be contracted for and paid directly by Tenant. Base Rent shall be payable
monthly, in equal monthly installments, in advance, on the first day of each
calendar month of the Term, without prior notice, demand, deduction or offset.

     1.5.1 Subject to the provisions of Section 1.5.2 below, the annual Base
Rent for the Premises (monthly installments of which may be referred to herein
as "Monthly Base Rent") for the initial Lease Year of the Term shall be Twenty
Three Dollars and Fifty Cents ($23.50) per square foot of the Premises.
Thereafter, as of the first twelve (12) month anniversary of the Commencement
Date and each annual anniversary thereafter, the Base Rent shall be increased to
an amount equal to one hundred three percent (103%) of the Base Rent for the
immediately preceding Lease Year.

     1.5.2 In the event Tenant exercises its Renewal Option in
accordance with Section 51 of this Lease, Base Rent and escalations for the
Renewal Term under this Lease shall be as set forth in Section 51 below.

         F. Additional Rent. Tenant's Share of Real Estate Taxes (as defined in
Section 10), Operating Costs (as defined in Section 9) and any other sum owed or

deduction. Estimates of those items of Additional Rent described in Section 9
and Section 10 of this Lease shall be provided by Landlord to Tenant in
accordance with the terms of Sections 9 and 10 hereof, and shall be payable

<PAGE>   9
         II.  PAYMENT OF BASE RENT & ADDITIONAL RENT.

Tenant shall pay Landlord the Base Rent and Additional Rent due under this Lease
without prior notice, demand, deduction or offset, in lawful money of the United
States. Base Rent and Additional Rent shall be paid at the address noted in
Section 1.8, or to such other party or at such other place as Landlord may
hereafter from time to time designate in writing. Base Rent and Additional Rent
under this Lease for any partial month at the beginning or end of the Lease Term
shall be prorated. Except for monthly installments of estimated Additional Rent
as set forth in Sections 9 and 10 of this Lease, or as otherwise provided in
this Lease, all payments of Additional Rent shall be paid no later than ten (10)
business days after the date Landlord notifies Tenant in writing of the amount
thereof. In the event of any dispute concerning the computation of the amount of
any Additional Rent due, Tenant shall pay the amount specified by Landlord
pending the resolution of the dispute, and, subject to Section 9.4 hereof, such
payment shall be without prejudice to Tenant's right to continue to challenge
the disputed computation.

         III. SECURITY AND ADVANCE DEPOSIT.
         
         A. Security Deposit. Simultaneously with the execution of this Lease by
Tenant, Tenant shall provide Landlord with a security deposit in an amount equal
to One Hundred Fifty Thousand Dollars ($150,000.00) (the "Security Deposit").
The Security Deposit shall constitute security for payment of Base Rent and
Additional Rent and for any and all other obligations of Tenant under this
Lease. If Tenant defaults, beyond any applicable cure period, with respect to
any covenant or condition of this Lease, including but not limited to the
payment of Base Rent, Additional Rent or any other payment due under this Lease,
and the obligation of Tenant to maintain the Premises and deliver possession
thereof back to Landlord at the expiration or earlier termination of the Lease
Term in the condition required herein, then Landlord may (without any waiver of
Tenant's default being deemed to have occurred) apply all or any part of the
Security Deposit to the payment of any sum in default beyond any applicable cure
period, or any other reasonable sum which Landlord may be required or deem
necessary to spend or incur by reason of Tenant's default, or to satisfy in part
or in whole any damages suffered by Landlord as a result of Tenant's default
which continues to exist beyond any applicable cure period. In the event of such
application, Tenant shall promptly deposit with Landlord the amount necessary to
restore the Security Deposit to the full amount set forth above. The parties
expressly acknowledge and agree that the Security Deposit is not an advance
payment of Base Rent or Additional Rent, nor a measure of Landlord's damages in
the event of any default by Tenant. If Tenant shall have fully complied with all
of the covenants and conditions of this Lease, but not otherwise, the amount of
the Security Deposit then held by Landlord shall be repaid to Tenant within
thirty (30) days after the expiration or sooner termination of this Lease. In
the event of a sale or transfer of Landlord's estate or interest in the
Building, Landlord shall transfer the Security Deposit to the purchaser or
transferee, and upon such transfer Landlord shall be considered released by
Tenant from all liability for the return of the Security Deposit, provided such
assignee assumes all prospective liability of Landlord hereunder. The Security
Deposit shall
<PAGE>   10
be posted in cash or by letter of credit, and, if in the form of letter of
credit shall be a clean, irrevocable letter of credit from an institution and in
form and substance reasonably satisfactory to Landlord in all respects. If in
the form of letter of credit, the same shall be "evergreen" and shall be renewed
automatically on an annual basis throughout the Term (or, alternatively, a
replacement letter of credit shall be furnished to Landlord, which letter of
credit must satisfy all of the conditions set forth above and which replacement
letter of credit shall be delivered not later than thirty (30) days prior to the
then scheduled expiry date of the existing letter of credit); failing which
Landlord shall be entitled to draw thereon and hold the proceeds therefrom in
cash as the Security Deposit hereunder.

3.2 Advance Deposit. Simultaneously with the execution of this Lease by Tenant,
Tenant shall deposit with Landlord the sum of $27,439.00 as a deposit of the
first month's Rent (the "Advance Deposit"), which shall be applied by Landlord
on behalf of the Tenant to the payment of the first month's Rent when due and
payable. Any good faith deposit made at the time Tenant executed and delivered
to Landlord any letter of intent or proposal to lease shall be applied toward
the amount of the Advance Deposit. The Advance Deposit, prior to its being
applied to the payment of monthly Rent, shall constitute security for the
payment and performance by Tenant of all of Tenant's obligations, covenants,
conditions and agreements under this Lease, but shall not be deemed liquidated
damages, but shall be applied in reduction of Tenant's total obligation(s) to
Landlord.

3.3 No Separate Account. Landlord shall not be obligated to hold the Security
Deposit (if converted to cash) or the Advance Deposit in a separate account from
other Building or Project funds.

3.4 Reduction of Security Deposit. Provided that no Default or Event of Default
then exists by or on behalf of Tenant hereunder, and further provided that there
then exists no condition or situation which, with the giving of notice or the
passage of time could constitute a default or Event of Default by or on behalf
of Tenant hereunder, commencing as of the fourth annual anniversary of the
Commencement Date and continuing (subject to the foregoing condition) on each
annual anniversary thereafter, Tenant shall have the right to reduce the
Security Deposit by an amount equal to twenty-five percent (25%) of the amount
of the original Security Deposit such that, provided the foregoing condition is
met, as of the expiration of the seventh (7th) Lease Year, the Security Deposit
shall be extinguished. In the event the Security Deposit is in the form of a
letter of credit, such reduction shall take place by replacement letter of
credit in form and substance consistent with Section 3.1 above, and Tenant
acknowledges and agrees that Landlord shall have no obligation to release the
then existing letter of credit to Tenant until an original replacement letter of
credit consistent with this Article 3 has been delivered to Landlord.

         IV. USES; TENANT COVENANTS.

         A. Permitted Uses. The Premises are to be used for general office,
network operation center and administration purposes and such other uses
incidental to such uses and 
<PAGE>   11
consistent with the operation of a first class office building as may be
permitted by applicable law, provided such uses shall not include any retail,
industrial or manufacturing use.

         B. Other General Use Covenants. Tenant shall not commit or allow to be
committed any waste upon the Premises, or any public or private nuisance.
Tenant, at its expense, shall comply with all laws relating to its use and
occupancy of the Premises and shall observe the Rules and Regulations attached
hereto as Exhibit D. No act shall be done in or about the Premises that is
unlawful, or which will increase the existing rate of insurance on the Building.
To the best of Landlord's knowledge, the proposed use will not increase the
existing rate of insurance on the Building. In the event of a breach of the
covenant set forth in the immediately preceding sentence regarding insurance
rates, Tenant shall cease the activity giving rise to such increase and, to the
extent any increased insurance premiums were in fact paid by Landlord as a
result of such activity, Tenant shall pay to Landlord any and all such increases
in insurance premiums resulting from such breach, provided that so long as
Tenant continues to pay such increases in premiums, and provided that the
activity giving rise to such increased premiums is an activity permitted under
Section 4.1, above, the continuation of such activity by Tenant shall not be
prohibited or constitute a breach of this Lease.

         V. ENVIRONMENTAL PROVISIONS; RECYCLING. 

         A. General. Tenant agrees to comply (and to cause its agents,
employees, contractors and, while within the Premises, invitees to comply) with
any and all applicable Environmental Laws (as defined below) in connection with
(1) Tenant's use and occupancy of the Premises, (2) any use and occupancy of the
Premises arising in connection with any assignment of this Lease, or sublease or
license of the Premises or any part thereof, and (3) any other fact or
circumstance the existence of which legally imposes on Tenant the obligation to
so comply therewith. Tenant shall provide all information within Tenant's
control requested by Landlord and/or governmental authorities in connection with
Environmental Laws or Hazardous Materials (defined below) relating to the
matters contemplated in the preceding sentence.

         B. Tenant's Warranties and Covenants

     During the Term and any Renewal Term (as hereafter defined) of the Lease,
Tenant warrants, represents and covenants to and with Landlord as follows:

                  1. Tenant will not introduce, or permit or suffer the
introduction, within the Premises or the Project of (A) asbestos in any form,
(B) urea formaldehyde foam insulation, (C) transformers or other equipment which
contain dielectric fluid containing polychlorinated biphenyls, or (D) except as
permitted below, any flammable explosives, radioactive materials or other
substance constituting "hazardous materials" or "hazardous wastes" pursuant to
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended (42 U.S.C. Sections 9601 et seq.), the Hazardous Materials
<PAGE>   12
Transportation Act, as amended (49 U.S.C. Sections 1801 et seq.), the Resource
Conservation and Recovery Act, as amended (42 U.S.C. Sections 9601 et seq.) and
the regulations adopted and promulgated pursuant thereto, the Federal Water
Pollution Control Act (33 U.S.C. Section 1251 et seq.), the Clean Air Act (42
U.S.C. Section 7401 et seq.), and in the regulations adopted and publications
promulgated pursuant thereto, or successor legislation thereto, or any other
Federal, state or local environmental law, ordinance, rule, regulation and/or
other statute of a governmental or quasi-governmental authority relating to
pollution or protection of the environment (collectively, "Environmental Laws").
The substances described in (A), (B), (C) or (D) above are hereinafter
collectively referred to herein as "Hazardous Materials".

                  2. Except as expressly permitted hereby, the Premises will
never be used by Tenant for any activities involving, directly or indirectly,
the use, generation, treatment, transportation, storage or disposal of any
Hazardous Materials, or to refine, produce, store, handle, transfer, process or
transport Hazardous Materials.

                  3. Tenant (A) shall comply with the Environmental Laws and all
other applicable laws, rules and regulations or orders pertaining to health, the
environment or Hazardous Materials, in so far as such laws pertain to Tenant's
use and occupancy of the Premises or the need for such compliance arises due to
the acts or omissions of Tenant, its agents, employees, contractors, invitees
(while within the Premises), subtenants or assignees, (B) shall not, except as
specifically permitted hereby, store, utilize, generate, treat, transport or
dispose of (or permit or acquiesce in the storage, utilization, generation,
transportation, treatment or disposal of) any Hazardous Materials on or from the
Premises, (C) shall cause its agents, employees, licensees, contractors,
invitees (while within the Premises), subtenants and assignees to comply with
the representations, warranties and covenants herein contained and be
responsible for any non-compliance by any such party(ies), (D) agrees that no
portion of the Premises will be used by Tenant or any assignee or subtenant of
Tenant as a landfill or a dump, and (E) will not install any underground tanks
of any type.

                  4. In the event of any future storage, presence, utilization,
generation, transportation, treatment or disposal of Hazardous Materials in, on
or about the Premises, or in the event of any Hazardous Materials Release (as
hereinafter defined) which in either case is attributable, in whole or in part,
to the presence of Hazardous Materials existing in, on or about on the Project
subsequent to the Commencement Date and is caused, directly or indirectly, by
Tenant or Tenant's agents, employees, contractors, licensees, invitees (while
within the Premises), sub-tenants or assignees, or is otherwise Tenant's
responsibility under the terms of this Lease, Tenant shall, at the direction of
Landlord or any federal, state, or local authority or other governmental
authority, remove or cause the removal of any such Hazardous Materials and
rectify any such Hazardous Materials Release, and otherwise comply or cause
compliance with the laws, rules, regulations or orders of such authority, all at
the expense of Tenant, including without limitation, the undertaking and
completion of all investigations, studies, sampling and testing and all
remedial, removal and other actions necessary to clean up and remove all
Hazardous Materials, on, from or affecting the Premises. If, under such
circumstances, Tenant shall fail to proceed with such removal or
<PAGE>   13
otherwise comply with such laws, rules, regulations or orders within the cure
period permitted under the applicable regulation or order, the same shall
constitute a default under this Lease and, upon forty eight (48) hours notice
given by Landlord to Tenant, Landlord may, but shall not be obligated to, take
such action as may be reasonably necessary under the circumstance to eliminate
such Hazardous Materials from the Premises or otherwise comply with the
applicable law, rule, regulation or order, acting either in its own name or in
the name of Tenant pursuant to this Section, and the cost thereof shall be borne
by Tenant and thereupon become due and payable as Additional Rent hereunder;
provided, however, that Landlord shall not exercise its self-help rights
hereunder, nor exercise any right otherwise provided herein to terminate this
Lease or Tenant's right of possession due to Tenant's failure or inability to
correct such problem within a time certain as long as Tenant is at all times
using its best efforts its efforts to correct the problem (provided however,
that if Landlord determines, in its reasonable discretion, that there exists a
substantial risk of governmental enforcement action against Landlord, or
governmental or third party civil liability to Landlord, if Landlord fails to
take independent action immediately to remediate an environmental problem which
is otherwise Tenant's responsibility under this Section 5, then Landlord shall,
notwithstanding Tenant's continuing best efforts to correct the problem, be
entitled to take such independent action, and to recover the reasonable and
actual costs associated therewith from Tenant). Tenant shall give to Landlord
and its authorized agents and employees access to the Premises for such purposes
and hereby specifically grants to Landlord a license to remove the Hazardous
Materials and otherwise comply with such applicable laws, rules, regulations or
orders, acting either in its own name or in the name of the Tenant pursuant to
this Section.

                  5. Landlord represents, warrants and covenants that to the
best of its current actual knowledge, as of the date of execution hereof, the
Land is free from any Hazardous Materials and is not in violation of any
Environmental Laws. Tenant shall not be liable for the performance of any
remedial action required, fines, penalties or any other charges which may be
assessed relating to any Hazardous Materials in existence at or on the Premises
as of the Commencement Date.

                  6. Each of Tenant and Landlord hereby indemnifies and holds
the other and their respective shareholders, constituents, subsidiaries,
affiliates, officers, directors, partners, employees, agents and trustees
harmless from, against, for and in respect of, any and all damages, losses,
settlement payments, obligations, liabilities, claims, actions or causes of
actions, encumbrances, fines, penalties, and costs and expenses suffered,
sustained, incurred or required to be paid by any such indemnified party
(including, without limitation, reasonable fees and disbursements or attorneys,
engineers, laboratories, contractors and consultants) because of, or arising out
of or relating to a violation of any of the indemnifying party's
representations, warranties and covenants under this Section, including any
Environmental Liabilities (as hereinbelow defined) arising therefrom. For
purposes of this indemnification clause, "Environmental Liabilities" shall
include all costs and liabilities with respect to the presence, removal,
utilization, generation, storage, transportation, disposal or treatment of any
Hazardous Materials or any release, spill, leak, pumping, pouring, emitting,
emptying, discharge, injection, escaping, leaching, dumping or 
<PAGE>   14
disposing into the environment (air, land or water) of any Hazardous Materials
(each a "Hazardous Materials Release"), including without limitation, cleanups,
remedial and response actions, remedial investigations and feasibility studies,
permits and licenses required by, or undertaken in order to comply with the
requirements of, any federal, state or local law, regulation, or agency or
court, any damages for injury to person, property or natural resources, claims
of governmental agencies or third parties for cleanup costs and costs of
removal, discharge, and satisfaction of all liens, encumbrances and restrictions
on the Premises relating to the foregoing. The foregoing notwithstanding, the
foregoing indemnifications shall not encompass consequential damages or damages
related to loss of business or business interruption which may arise on account
of the presence of any Hazardous Materials on or about the Project. The
foregoing indemnification and the responsibilities of Tenant and Landlord under
this Section shall survive the termination or expiration of this Lease.

                  7. Tenant shall promptly notify Landlord in writing of the
occurrence of any Hazardous Materials Release or any pending or threatened
regulatory actions, or any claims made by any governmental authority or third
party, relating to any Hazardous Materials or Hazardous Materials Release on or
from the Premises, and shall promptly furnish Landlord with copies of any
correspondence or legal pleadings or documents in connection therewith. Landlord
shall have the right, but shall not be obligated, to notify any governmental
authority of any state of facts which may come to its attention with respect to
any Hazardous Materials or Hazardous Materials Release on or from the Premises
following consultation with Tenant.

                  8. Tenant agrees that Landlord shall have the right (but not
the obligation) to conduct, or to have conducted by its agents or contractors,
such periodic environmental inspections of the Project as Landlord shall
reasonably deem necessary or advisable from time to time. Landlord shall provide
Tenant with no less than seventy-two (72) hours prior notice of any such
inspection within the interior of the Premises, except in case of an emergency,
in which case only such notice as may be practicable under the circumstance
shall be required. The cost of any such inspection shall be borne by Tenant in
the event such inspection determines that Tenant has breached the covenants set
forth in Section 5.2.3 above.

         C. Permitted Materials. Notwithstanding the foregoing, Tenant and its
assignees, subtenants and licensees shall be permitted to store reasonable
amounts of Hazardous Materials that are typically used in an ordinary general
office use environment such as ordinary cleaners, printer and duplication
supplies and similar materials (the "Permitted Materials") provided such
Permitted Materials are properly used, stored and disposed of in a manner and
location meeting all Environmental Laws. Any such use, storage and disposal
shall be subject to all of the terms of this Section (except for the terms
prohibiting same), and Tenant shall be responsible for obtaining any required
permits and paying any fees and providing any testing required by any
governmental agency with respect to the Permitted Materials. If Landlord in its
reasonable opinion determines that any Permitted Materials are being improperly
stored, used or disposed of, then Tenant shall immediately take such 
<PAGE>   15
corrective action as requested by Landlord. Should Tenant fail to take such
corrective action within three (3) business days of receipt of such notice (or
such shorter time as may be set forth in such notice in the event Landlord
determines that the same presents a possible threat to person or property within
the Building), Landlord shall have the right to perform such work on Tenant's
behalf and at Tenant's sole expense, and Tenant shall promptly reimburse
Landlord for any and all costs associated with said work.

         D. Recycling Regulations. Landlord shall, as an Operating Cost
hereunder, provide receptacles and containers as necessary for Tenant to comply
with all orders, requirements and conditions now or hereafter imposed by any
ordinances, laws, orders and/or regulations (hereinafter collectively called
"regulations") of any governmental body having jurisdiction over the Premises or
the Building regarding the collection, sorting, separation and recycling of
waste products, garbage, refuse and trash (hereinafter collectively called
"waste products").

         VI. LATE CHARGES; INTEREST
<PAGE>   16

         A. Tenant hereby acknowledges that late payment to Landlord of Base
Rent or Additional Rent will cause Landlord to incur administrative costs and
loss of investment income not contemplated by this Lease, the exact amount of
which will be extremely difficult to ascertain. If any Base Rent or Additional
Rent due from Tenant is not received by Landlord or Landlord's designated agent
by that date which is seven (7) days after the date the same is due (or, in the
event that Tenant is late in payment more than two [2] times in any twelve [12]
month period, then thereafter in the event any such payment is not received by
Landlord by the date the same is due), then Tenant shall pay to Landlord a late
charge equal to five percent (5%) of such overdue amount. The parties hereby
agree that such late charges represent a fair and reasonable estimate of the
administrative cost that Landlord will incur by reason of Tenant's late payment.
Landlord's acceptance of such late charges shall not constitute a waiver of
Tenant's Default with respect to such overdue amount or otherwise estop Landlord
from exercising any of the other rights and remedies granted hereunder.

         B. In addition to the administrative late charge provided for under
Section 6.1, above, if any Base Rent or Additional Rent or any other sum due
hereunder from Tenant to Landlord is not paid by that date which is seven (7)
days after the date the same is due (or, in the event that Tenant is late in
payment more than two [2] times in any twelve [12] month period, then thereafter
in the event any such payment is not received by Landlord by the date the same
is due), then the entire unpaid amount shall bear interest from the date
originally due until the date paid at an annual rate of interest equal to the
"prime rate" of interest as published in the Wall Street Journal (or, if not
published, as established by the then largest national banking association in
the United States of America) from time to time (the "Prime Rate") plus three
percent (3%) (the "Default Rate").

         VII. REPAIRS AND MAINTENANCE.

7.1 Landlord's Obligations. Landlord shall be responsible for and shall
maintain, repair, replace and keep in good operating condition, comparable to
similar properties in the McLean, Virginia area, the Common Areas (as defined in
Section 39 below) (including, without limitation, the lobbies, elevators,
stairs, grounds, loading areas and corridors), the roofs, foundations, floors,
ceilings, walls, windows, load-bearing elements, conduits and structural walls
and other structural elements of the Building, the underground utility and sewer
pipes of the Building, all base building mechanical, electrical, plumbing, HVAC
system and the sprinkler system and other fire and life-safety systems, and the
adjacent parking structure and surface parking facility, the cost of which shall
be included within Operating Costs except to the extent set forth in Section
9.6, hereof; provided that, to the extent the need for any such repairs or
replacements arise as a the result of the negligence or willful misconduct of
Tenant (or Tenant's agents, employees, contractors, invitees (while within the
Premises), assignees or sub-tenants) and the same is not covered under the
policies of casualty insurance which are required to be carried by the parties
pursuant to this Lease (in which case the proceeds of such insurance will be
utilized to satisfy the cost thereof), the cost
<PAGE>   17
of such repairs or replacements shall be reimbursable by Tenant to Landlord as
Additional Rent under this Lease, and such reimbursement shall be due not later
than ten (10) business days after Landlord's written demand therefore. 

7.2. Repair Standards. All repairs and maintenance required of Landlord pursuant
to this Section or elsewhere in this Lease shall be performed in accordance with
standards applicable to comparable office buildings in McLean, Virginia, and
performed in a timely and diligent fashion. Landlord agrees to diligently attend
to any routine repairs or maintenance needs brought to its attention by Tenant
as soon as reasonably practicable and in a manner calculated to minimize to the
extent possible disruption of Tenant's business activities.

7.3 Tenant's Obligations. Subject to Landlord's obligations as set forth in
Section 7.1 above and its right of access pursuant to Section 18, and except for
janitorial and cleaning services (to the extent provided for under Section 8.1,
below), Tenant shall be exclusively responsible for all repairs and maintenance
to the interior non-structural portions of the Premises. Tenant shall promptly
report in writing to Landlord any defective condition in the Premises known to
Tenant which Landlord is required to repair, and failure to so report such
defects shall excuse any delay by Landlord in commencing and completing such
repair to the extent the same would otherwise be Landlord's responsibility under
this Lease, provided that (i) Landlord shall not be so excused if Landlord had
actual knowledge of the need for such repair independent of Tenant's
notification, and (ii) once Landlord is notified or has actual knowledge of the
need for such repair, Landlord's repair obligation under Section 7.1, above,
shall be fully effective as to such item (and, to the extent any delay in
reporting such defects results in the otherwise avoidable need to perform a
capital repair or replacement which under Section 9.5 is excluded from Operating
Costs, in lieu of an ordinary repair which under Section 9.5 would be included
within Operating Costs, Tenant shall be responsible for the reasonable and
actual cost of such capital repair or replacement unless Tenant can demonstrate
that a capital repair or replacement to such item would in any event have been
necessary within twelve (12) months thereafter, even if the defective condition
had been reported to Landlord or known by Landlord in a timely fashion).
Landlord's obligation to make repairs shall be limited to the express
obligations stated herein.

         VIII. UTILITIES AND SERVICES.

         A. Services. Landlord shall furnish Tenant with the following services
and facilities, the cost of all of which shall be deemed Operating Costs
hereunder: (i) at least one elevator in the Building subject to call at all
times, including Sundays and holidays; (ii) zoned heating, ventilation and air
conditioning within the Premises at all times, within the temperature and
humidity ranges usually furnished in comparable office buildings in the McLean,
Virginia area (provided that such services in the Common Areas of the Building
shall only be provided during business hours, excluding holidays); (iii)
balancing of the HVAC system when necessary in an effort to provide reasonably
uniform air temperatures throughout the zones within the Premises; (iv) hot and
cold running water sufficient for needs attributable to a general office use;
(v) public lavatory facilities and supplies and janitorial and char services,
including trash removal and recycling, Monday through Friday, except 
<PAGE>   18
holidays; (v) replacement of light bulbs (in fixed lighting fixtures only)
throughout the Premises; and (vi) access to the Project 24 hours a day, 365 days
a year, including holidays. For purposes hereof, "holidays" shall be: New Year's
Day, Memorial Day, July 4th, Labor Day, Thanksgiving, and Christmas, and
business hours shall be 7:30 a.m. to 6:00 p.m. Monday through Friday, excluding
holidays, and 9:00 a.m. to 2:00 p.m. on Saturdays, excluding holidays. Landlord
shall provide perimeter security for the Premises limited to a Data Watch or
similar key-card system, 24 hours a day, 365 days a year. All key-cards for such
system shall be obtained by Tenant in accordance with Section 42 hereof.

8.2 Additional Services. If Tenant requires cleaning services, light bulb or
fixture replacement or other services on weekends or holidays, Landlord shall
make reasonable efforts to provide such additional service after reasonable
prior written request therefor from Tenant, and Tenant shall reimburse Landlord
for such additional service within ten (10) days of request therefore, at the
actual direct cost to Landlord. Additionally, the Premises shall be separately
metered for electrical consumption and therefor Tenant shall pay the cost of all
HVAC services for the Premises. Landlord shall provide such additional services
provided that Tenant shall pay 100% of the cost thereof as Additional Rent
hereunder.

8.3 Additional Provisions. Except as specifically and expressly set forth
hereinbelow, in no event shall Landlord be liable to Tenant for (a) any damage
to the Premises, or (b) any loss, damage or injury to any property therein or
thereon, or (c) any claims for the interruption of or loss to Tenant's business
or for any damages or consequential losses occasioned by bursting, rupture,
leakage or overflow of any plumbing or other pipes or other similar cause in,
above, upon or about the Premises or the Building, unless such loss, damage or
injury is the result of the gross negligence or willful misconduct of Landlord,
and is not covered by the insurance required to be carried by Tenant hereunder.
If any public utility or governmental body shall require Landlord or Tenant to
restrict the consumption of any utility or reduce any service to the Premises or
the Building, Landlord and Tenant shall comply with such requirements, without
any abatement or reduction of the Base Rent, Additional Rent or other sums
payable by Tenant hereunder.

8.4 Electrical Service. The Premises will be separately metered for electrical
service in accordance with the provisions of EXHIBIT C attached hereto. Tenant
shall be solely responsible for obtaining electrical service for the Premises
from the appropriate utility, and for the payment of all costs of electrical
service provided to the Premises directly to the service provider. Landlord
shall have no liability or obligation in respect of or as a result of Tenant's
failure to obtain or maintain electrical service to the Premises.

         IX. INCREASES IN OPERATING COSTS.
<PAGE>   19
9.1 Defined. For each calendar year or portion thereof during the Term, Tenant
shall pay as additional rent to Landlord, without diminution, set-off or
deduction, Tenant's Share of an amount (hereinafter referred to as "Expense
Increases") equal to the difference between:

     (A) "Tenant's Share" of "Operating Costs" (defined in Section 9.5, below)
for such calendar year; and

     (B) "Tenant's Share" of "Operating Costs" for the "Operating Costs Base
Year" (defined below).

9.2 Base Year. For all purposes hereof, the Operating Costs Base Year shall be
the 1999 calendar year.

9.3 Estimated Payments. Commencing with the first day of the second Lease Year
of the Lease Term, Tenant shall make monthly installment payments toward
Tenant's Share of Expense Increases on an estimated basis, based on Landlord's
reasonable estimate of Expense Increases for such calendar year. Landlord shall
provide its estimate of such costs with as much advance notice as is reasonably
possible. Tenant shall pay Landlord, as additional rent, commencing on the first
day of the month immediately following the last day of the Operating Costs Base
Year, and on the first day of each month thereafter during the Term, one-twelfth
(1/12th) of Landlord's estimate of Tenant's Share of Expense Increases for the
then-current calendar year. If at any time or times during such calendar year,
it appears to Landlord that Tenant's Share of Expense Increases for such
calendar year will vary from Landlord's estimate by more than five percent (5%)
on an annualized basis, Landlord may, by written notice to Tenant, revise its
estimate for such calendar year and Tenant's estimated payments hereunder for
the balance of such calendar year shall thereupon be based on such revised
estimate.

9.4 Annual Reconciliation. Within one hundred twenty (120) days after the end of
each calendar year after the Operating Costs Base Year, Landlord shall provide
to Tenant a statement (the "Expense Statement") setting forth the total
Operating Costs for such calendar year and Tenant's Share of Expense Increases
for such year, calculated in accordance with Section 9.1, above. Within fifteen
(15) days after the delivery of such Expense Statement, Tenant shall pay to
Landlord any deficiency between the amount shown as Tenant's Share of Operating
Costs for such calendar year and the estimated payments made by Tenant toward
such amount in accordance with Section 9.3, above. In the case of excess
estimated payments, the excess shall be applied against estimated payments of
Operating Costs for the subsequent calendar year, unless the Lease shall have
expired, in which event Landlord shall refund such excess, without interest,
with the delivery of the Expense Statement.

9.5 Operating Costs. The term "Operating Costs" shall mean any and all expenses
incurred by Landlord in connection with the operation, management, maintenance
and repair of the Building and the Land, and all easements, rights and
appurtenances thereto, including, but not limited to: (a) the cost of the
personal property used in conjunction therewith; (b) costs to repair and
maintain the Building and/or roof; (c) all expenses paid or incurred by Landlord
for electricity for the Common Areas of the Building, including any surcharges
imposed, and for water, gas, sewers, oil and utility services for the Building
(except as charged directly to tenants); (d) the costs and expenses incurred in
connection with the provision of the utilities
<PAGE>   20
and services set forth in Section 8, above, including without limitation the
maintenance, repair and replacement of the Building systems furnishing such
utilities and/or services; (e) Building supplies and materials; (f) cleaning and
janitorial services in or about the Premises, the Building (including without
limitation common areas) and the Land; (g) window glass replacement, repair and

governmental laws, rules, orders or regulations enacted after the date hereof;
(j) utility taxes; (k) compensation (including employment taxes, salaries,
wages, medical, surgical, and general welfare benefits (including health,
accident and group life insurance), pension payments, payroll taxes, and
worker's compensation insurance) for all persons who perform duties in
connection with the operation, management, maintenance and repair of the
Building (equitably pro-rated to the extent any such personnel is not employed
at the Building on a full time basis); (l) any capital expenditures incurred
either to reduce Operating Costs, to comply with any governmental law, order,
regulation or other requirement (e.g., a code-mandated life safety system)
enacted after the date hereof, or to replace existing equipment and machinery
necessary to the day to day operation of the Building, or which are capital
replacements (i.e., replacements of common area or common usage Building
components and systems in lieu of capital repairs otherwise required to be made
thereto, but excluding replacement of the Building roof, parking lot and/or
garage), provided that any capital expenditure which does not result in a
quantifiable reduction of Operating Costs shall be amortized over the useful
life thereof, not to exceed ten (10) years, and only the amortized annual
portion, together with interest at a rate of twelve percent (12%) per annum,
shall be recoverable by Landlord under this Section 9.5(l) in any one year; (m)
cost of premiums for casualty, liability, elevator, workman's compensation,
boiler and machinery, sprinkler leakage, rent loss, use and occupancy and other
insurance; (n) license, permit and inspection fees, excluding Tenant
Improvements; (o) management fees; (p) consulting fees in connection with the
provision of common area maintenance services; (q) costs of continuing education
and professional trade and association dues for Building management staff; (r)
vault space rentals and public space rentals, if any; (s) personal property

or other assessments for project-wide common area services; and (bb) any other
expense or charge whether or not hereinbefore described which, in accordance
with generally accepted accounting and management practices, would be considered
a reasonable and necessary expense of maintaining, managing, operating or
repairing the Building and/or the Land. 

9.6 Exclusions. Notwithstanding the foregoing, Operating Costs shall not include
any of the following: (1) capital expenditures, except those set forth in item
9.5 (l), above; (2) costs of any special services rendered to individual tenants
(including Tenant), for which a special, separate charge shall be made (and
shall be payable within ten (10) days of written demand); (3) painting,
redecorating or other work which Landlord performs for specific tenants, the
expenses of which are paid by such tenants; (4) Real Estate Taxes (as defined in
Section 10); 
<PAGE>   21
(5) depreciation or amortization of costs required to be capitalized in
accordance with generally accepted accounting practices (except as set forth in

salaries, wages, or other compensation paid to officers or executives of
Landlord in their capacities as officers and executives; (10) and any other
expenses for which Landlord actually receives direct reimbursement from
insurance, condemnation awards, other tenants or any other source but excluding
general payments of Expense Increases pursuant to this Section 9 by Tenant and
other tenants of the Building.

9.7 Further Adjustment. In the event Landlord shall furnish any utility or
service which is included in the definition of Operating Costs to less than one
hundred percent (100%) of the rentable area of the Building because (i) the
average occupancy level of the Building for the Base Services Year and/or any
subsequent calendar year was not one hundred percent (100%) or more of full
occupancy, (ii) any such utility or service is not required by or provided to
one or more of the tenants or occupants of the Building, or (iii) any tenant or
occupant is itself obtaining or providing any such utility or services, then the
Operating Costs for such year (including, as set forth above, the Base Services
Year) shall be adjusted to include all additional costs, expenses and
disbursements that Landlord reasonably determines would have been incurred if
Landlord had provided all such utilities and services to all tenants and
occupants in the Building, and shall be allocated among the tenants by the
Landlord to reflect those costs which would have occurred had the Building been
one hundred percent (100%) occupied during the year in question and such
utilities and services provided to all tenants. The intent of this Section 9.7
is to ensure that the reimbursement of all Operating Costs is fair and equitably
allocated among the tenants receiving the utilities and services in question. In
the calculation of Operating Costs hereunder, no expense shall be charged more
than once, and in no event shall any such calculation result in payment by
Tenant of an amount greater than Tenant's Share of actual Expense Increases for
the applicable time period.

9.8 Multi-Project Operating Costs. The Building is a part of a larger project or
development and as such, Landlord shall have the right (but not the obligation)
to allocate to the Building an appropriate portion of those Operating Costs
which are incurred with respect to the project as a whole. By way of example,
landscaping costs for a multi-building project shall be allocated on a
proportionate basis between all tenantable buildings in the project.

         X. INCREASES IN REAL ESTATE TAXES

10.1 Defined. For each calendar year or portion thereof during the Term, Tenant
shall pay as additional rent to Landlord, without diminution, set-off or
deduction, Tenant's share of an amount (hereinafter referred to as "Tax
Increases") equal to the difference between:

     (A) "Tenant's Share" of "Real Estate Taxes" (defined in Section 10.5,
below) paid in such calendar year; and

     (B) "Tenant's Share" of "Real Estate Taxes" paid in the "Real Estate Tax
Base Year" (defined below.)
<PAGE>   22
10.2 Base Year. For all purposes hereof, the Real Estate Tax Base Year shall be
the 1999 calendar year.

10.3 Estimated Payments. Commencing with the first day of the second Lease Year
of the Lease Term, Tenant shall make monthly installment payments toward
Tenant's Share of Tax Increases on an estimated basis, based on Landlord's
reasonable estimate of Tax Increases for such calendar year. Tenant shall pay
Landlord, as additional rent, commencing on the first day of the month
immediately following the last day of the Real Estate Tax Base Year, and on the
first day of each month thereafter during the Term, one-twelfth (1/12th) of
Landlord's estimate of Tenant's Share of Tax Increases for the then-current
calendar year. If at any time or times during such calendar year, it appears to
Landlord that Tenant's Share of Tax Increases for such calendar year will vary
from Landlord's estimate by more than five percent (5%) on an annualized basis,
Landlord may, by written notice to Tenant, revise its estimate for such calendar
year and Tenant's estimated payments hereunder for such calendar year shall
thereupon be based on such revised estimate.

10.4 Annual Reconciliation. Within one hundred twenty (120) days after the end
of each calendar year after the Real Estate Tax Base Year, Landlord shall
provide to Tenant a statement (the "Expense Statement") setting forth the total
Real Estate Taxes for such calendar year and Tenant's Share of Tax Increases for
the applicable year. Within fifteen (15) days after the delivery of such Expense
Statement, Tenant shall pay to Landlord any deficiency between the amount shown
as Tenant's Share of Tax Increases for such calendar year and the estimated
payments made by Tenant toward such amount in accordance with Section 10.3,
above. In the case of excess estimated payments, the excess shall be applied
against estimated payments of Real Estate Taxes for the subsequent calendar
year, unless the Lease shall have expired, in which event Landlord shall refund
such excess, without interest, with the delivery of the Expense Statement.

10.5 Real Estate Taxes. For purposes of this Lease, "Real Estate Taxes" shall
mean all taxes and assessments, general or special, ordinary or extraordinary,
foreseen or unforeseen, assessed, levied or imposed upon the Building or the
Land, or assessed, levied or imposed upon the fixtures, machinery, equipment or
systems in, upon or used in connection with the operation of the Building or the
Land under the current or any future taxation or assessment system or
modification of, supplement to, or substitute for such system. Real Estate Taxes
shall include all reasonable expenses (including, but not limited to, attorneys'
fees, disbursements and actual costs) incurred by Landlord in obtaining or
attempting to obtain a reduction of such taxes, rates or assessments, including
any legal fees and costs incurred in connection with contesting or appealing the
amounts or the imposition of any Real Estate Taxes. Landlord shall have the
right to pay any special assessment by installments, and in such event Real
Estate Taxes shall include such installments and interest paid on the unpaid
balance of the assessment. Real Estate Taxes shall not include income,
franchise, estate or sales tax imposed on Landlord as opposed to the Building or
Land.

         XI. ADDITIONAL PROVISIONS; OPERATING COSTS AND REAL ESTATE
             TAXES.
<PAGE>   23
         A. Partial Year; End of Term. To the extent that a more accurate method
of allocating same cannot be implemented by Landlord, Tenant's Share of
Operating Costs and Real Estate Taxes for any partial calendar year shall be
determined by multiplying the amount of Tenant's Share thereof for the full
calendar year by a fraction, the numerator of which is the number of days during
such partial year falling within the Term and the denominator of which is 365.
If this Lease terminates on a day other than the last day of a calendar year,
the amount of any adjustment to Tenant's Share of Real Estate Taxes with respect
to the year in which such termination occurs shall be prorated on the basis
which the number of days from January 1 of such year to and including such
termination date bears to 365; and any amount payable by Landlord to Tenant or
Tenant to Landlord with respect to such adjustment shall be payable within
thirty (30) days after delivery by Landlord to Tenant of the applicable Expense
Statement and Tax Statement with respect to such year.

         B. Other Taxes. In addition to Tenant's Share of Operating Costs and
Real Estate Taxes, Tenant shall pay, prior to delinquency, all personal property
taxes payable with respect to all property of Tenant located in the Premises or
the Building, and shall provide promptly, upon request of Landlord, written
proof of such payment.

         C. Covenant Regarding Timely Payment of Operating Costs and Real Estate
Taxes. Landlord covenants to pay all Operating Costs and Real Estate Taxes
before the same become delinquent, subject to Tenant's obligation to make the
payments contemplated by Article 9 and Article 10, above, in a timely fashion.
Tenant shall not be responsible for reimbursement to Landlord of any interest
charge or penalty for late payment by Landlord of Operating Costs and/or Real
Estate Taxes, provided that payment of Tenant's pro rata share of such expense
has been timely made by Tenant to Landlord pursuant to the terms of this Lease.

11.4 Contesting Real Estate Taxes. Landlord will have the right to employ a tax
consulting firm to attempt to assure a fair tax burden on the Project, provided
Landlord will use reasonable efforts to minimize the cost of such service. The
reasonable cost of such service shall be included in the Real Estate Taxes
hereunder in the year same were incurred or paid, at Landlord's election.
Additionally, during any such period, Landlord shall have the right, in its
reasonable judgment, to contest any tax assessment, valuation or levy against
the Project, and to retain legal counsel and expert witnesses to assist in such
contest and otherwise to incur expenses in such contest, and any reasonable
fees, expenses and costs incurred by Landlord in contesting any assessments,
levies or tax rate applicable to the Project, whether or not such contest is
successful, shall be included in Real Estate Taxes as set forth above. In the
event Landlord is successful in obtaining a reduction in any Real Estate Taxes
due for periods of time within the Term, provided any such reduction or credit
is obtained during the Term, Tenant shall share in the benefit of such reduction
(net of all costs, expenses and fees incurred by Landlord in pursuing and
obtaining such reduction) by applying Tenant's pro rata share of such reduction
or credit (to the extent the amount thereof was paid to Landlord in a timely
fashion pursuant to the terms of this Lease) to Tenant's Share of Tax Increases
next coming due.

11.5 Arbitration. Disputes regarding Operating Costs, Real Estate Taxes, and any
audit thereof, shall be subject to arbitration in accordance with the provisions
of Section 49 hereof.
<PAGE>   24
         XII. TENANT'S INSURANCE.

         A.  Coverage Requirements. Tenant shall during the Term of this Lease,
pro cure at its expense and keep in force the following insurance:

 ..............Commercial general liability insurance naming the Landlord and
              Landlord's managing agent as additional insureds against any and
              all claims for bodily injury and property damage occurring in or
              about the Premises or any appurtenances thereto covering the
              operation of the Tenant (its employees, agents, and invitees) and
              any subtenants, licensees and concessionaires of the Tenant. Such
              insurance shall be written on an "Occurrence Form" and shall

              thereto. Such insurance shall have a limit of not less than One

              Dollars ($2,000,000.00) general aggregate with an excess
              (umbrella) liability insurance in the amount of Two Million
              Dollars ($2,000,000.00) per occurrence and Two Million Dollars
              ($2,000,000.00) annually in the aggregate; provided, however that
              no such limits shall be deemed limitation of the liability of
              Tenant hereunder. If Tenant has other locations that it owns or
              leases, the policy shall include an aggregate limit per location
              endorsement. Such liability insurance shall be primary and not
              contributing to any insurance available to Landlord and Landlord's
              insurance shall be in excess thereto. In no event shall the limits
              of such insurance be considered as limiting the liability of
              Tenant under this Lease;

 ..............Personal property insurance insuring all equipment, trade
              fixtures, inventory, fixtures and personal property located within
              the Premises (excluding leasehold improvements, which shall be
              insured by and remain the property of Landlord). Such insurance
              shall be written on a replacement cost basis in an amount equal to
              one hundred percent (100%) of the full replacement value of the
              aggregate of the foregoing;

              Workers' compensation and occupational disease insurance, employee
              benefit insurance and any other insurance in the statutory amounts

              liability insurance with a limit of One Million Dollars
              ($1,000,000.00) for each accident.

              Business income insurance and loss of rental insurance in an
              amount equal to at least to eighteen (18) months Rent.

         B.  Rating; Certificates; Cancellation. The policies required to be
maintained by Tenant shall be with companies rated A-X or better in the most
current issue of Best's Insurance Reports. Insurers shall be licensed to do
business in the Commonwealth of 
<PAGE>   25
Virginia and domiciled in the USA. Any deductible amounts under any insurance
policies required hereunder shall be commercially reasonable. Certificates of
insurance and certified copies of the policies shall be delivered to Landlord
prior to the Commencement Date and annually thereafter at least thirty (30) days
prior to the expiration date of the old policy. Tenant shall have the right to
provide insurance coverage which it is obligated to carry pursuant to the terms
hereof in a blanket policy, provided such blanket policy expressly affords
coverage to the Premises and to Landlord as required by this Lease. Each policy
of insurance shall provide notification to Landlord and any mortgagee(s) of
Landlord at least thirty (30) days prior to any cancellation or modification to
reduce the insurance coverage.

         C.   Other. In the event Tenant does not purchase the insurance
required by this Lease or keep the same in full force and effect, and the same
is not corrected within one (1) business day following written notice thereof
from Landlord to Tenant, then Landlord may, but shall not be obligated to,
purchase the necessary insurance and pay the premium therefore. Tenant shall
repay to Landlord, as Additional Rent, any and all reasonable expenses
(including attorneys' fees) and damages which Landlord may sustain by reason of
the failure of Tenant to obtain and maintain insurance.

         XIII. LANDLORD'S INSURANCE.

         A.   Coverage. At all times during the Lease Term, Landlord will
maintain, the cost of which shall be reimbursable as an Operating Cost
hereunder, (a) fire and extended coverage insurance covering the Project,
including all of Tenant's Work, in an amount equal to one hundred percent (100%)
of the replacement value thereof, and (b) public liability and property damage
insurance in such amounts as Landlord deems reasonable from time to time.
Landlord shall also have the right to obtain such other types and amounts of
insurance coverage on the Building (including loss of rental insurance) and
Landlord's liability in connection with the Building as are customary or
advisable for a comparable office project in the McLean, Virginia area, as
determined by Landlord in Landlord's reasonable judgment. Any dispute regarding
the appropriateness of such additional insurance coverage shall be subject to
arbitration pursuant to Section 49 of this Lease.

         B.   Rating; Certificates; Cancellation. The policies required to be
maintained by Landlord shall be with companies rated A-X or better in the most
current issue of Best's Insurance Reports. Insurers shall be licensed to do
business in the Commonwealth of Virginia and domiciled in the USA. Any
deductible amounts under any insurance policies required hereunder shall be
commercially reasonable, in Landlord's reasonable judgement. Landlord shall have
the right to provide insurance coverage which it is obligated to carry pursuant
to the terms hereof in a blanket policy, provided such blanket policy expressly
affords coverage to the Project and to Tenant as required by this Lease.

         XIV. DAMAGE OR DESTRUCTION.

         A.   Damage Repair.

     14.1.1 If the Building or Premises shall be destroyed or rendered
untenantable, either wholly or in part, by fire or other casualty, then Landlord
shall, within thirty (30) days after
<PAGE>   26
the date of such casualty, provide Tenant with Landlord's good faith written
estimate (the "Estimate") of how long it will take to repair or restore the
Premises.

     14.1.2 If neither party elects to terminate this Lease in accordance with
the terms hereof following any casualty, then Landlord shall commence promptly
and diligently prosecute to completion the restoration of the Premises to their
previous condition, subject to Force Majeure as defined herein and delays caused
by Tenant; and pending substantial completion of such restoration, the Base Rent
and Additional Rent shall be abated in the same proportion as the untenantable
portion of the Premises bears to the whole thereof, and this Lease shall
continue in full force and effect.

     14.1.3 If Landlord estimates within the Estimate that it will require in
excess of one hundred eighty three (183) days after the date Tenant's right of
termination hereunder expires to fully repair or restore the Premises in
accordance herewith, then, within thirty (30) days after Landlord delivers
Tenant the Estimate, Tenant and Landlord shall each have the right to terminate
this Lease by written notice to the other, which termination shall be effective
as of the date of such notice of termination, and all liabilities and
obligations of Landlord and Tenant thereafter accruing shall terminate and be of
no legal force and effect except as otherwise specifically set forth herein.
Notwithstanding the foregoing, Tenant shall not have the right to terminate this
Lease if the fire or other casualty was the result of Tenant's negligence or
willful misconduct.

     14.1.4 If neither party elects to terminate the Lease and Landlord fails or
declines to exercise any other termination right pursuant to this Section 14,
Landlord will use all reasonable efforts to commence and complete its
restoration of the affected portions of the Premises promptly, and in the event
Landlord is unable to complete such restoration within one hundred eighty three
(183) days after the date Tenant's right of termination hereunder expires (or
such longer period as was referenced in the Estimate, if applicable), as such
period may be extended due to Force Majeure or due to any Tenant Delays (as such
term is defined in Exhibit C hereof, and not limited as to the number of days)
then within thirty (30) days after the expiration of such period (but in all
events prior to the date Landlord completes its restoration of the Premises),
Tenant shall again have the right to terminate this Lease upon thirty (30) days
prior written notice to Landlord; provided, however, that if Landlord
substantially completes such restoration (such that Tenant may lawfully re-enter
and occupy the Premises in accordance with the terms of this Lease) prior to the
end of the thirty (30) day notice period, Tenant's notice of termination shall
be deemed rescinded and ineffective for all purposes, and this Lease shall
continue in full force and effect. The provisions of this Section are in lieu of
any statutory termination provisions allowable in the event of casualty damage.

     14.1.5 If at any time in the course of its restoration of damaged portions
of the Premises, Landlord believes in good faith that its original Estimate is
no longer accurate for reasons other than Force Majeure (in which event the
provisions of Section 14.1.4 shall control), Landlord shall have the right to
deliver a revised Estimate to Tenant of the additional time period which
Landlord believes will be required to fully repair or restore the Premises in
accordance herewith, and, unless Tenant terminates this Lease by written notice
to Landlord within ten (10) business days after its receipt of such revised
Estimate from Landlord, Tenant shall be deemed to have agreed that, for all
purposes of this Section 14.1, the 183 day time limit otherwise imposed upon
completion of Landlord's restoration of the damaged portions of the Premises
shall be extended by the number of additional days needed to complete 
<PAGE>   27
estimated by Landlord within such revised Estimate. If Tenant elects to
terminate this Lease as to the damaged Building after receiving such a revised
Estimate from Landlord, as aforesaid, such termination shall be effective as of
the date of such notice of termination, and all liabilities and obligations of
Landlord and Tenant thereafter accruing hereunder with respect to such Building
shall terminate and be of no legal force and effect except as otherwise
specifically set forth herein.

         B. Reconstruction. If all or any portion of the Premises is damaged by
fire or other casualty and this Lease is not terminated in accordance with the
provisions hereof, then all insurance proceeds under the policy referred to in
Section 13.1 hereof that are recovered by Landlord on account of any such damage
by fire or casualty shall be made available for the payment of the cost of
repair, replacing and rebuilding.

         C. Business Interruption. Other than rental abatement as and to the
extent provided in Section 14.1, no damages, compensation or claim shall be
payable by Landlord for inconvenience or loss of business arising from
interruption of business, repair or restoration of the Building or Premises.

14.4 Repairs. Landlord's repair obligations, should it elect to repair, shall be
limited to the base Building, Common Areas and all interior improvements to and
property within the Premises which are covered or required to be covered
hereunder by Landlord's insurance. Landlord shall use reasonable efforts to
commence such repairs and restorations within a reasonable period after Landlord
elects to restore the Premises, and to complete such repairs within the time
frames referenced in Section 14.1, above. Tenant acknowledges that any such
repairs or restorations shall be subject to applicable laws and governmental
requirements, any disbursement requirements imposed by Landlord's mortgagee (if
any), and to delay in the process of adjusting any insurance claim associated
therewith; and delays resulting from any of the foregoing shall constitute a
"Force Majeure" hereunder, shall not in any event constitute a breach of this
Lease by Landlord, and shall extend the time for completing such restoration as
long as Landlord uses reasonable efforts to commence and complete such repairs
and restorations in a timely fashion.

14.5 End of Term Casualty. Anything herein to the contrary notwithstanding, if
more than thirty (30%) of the Premises is destroyed or damaged during the last
eighteen (18) months of the Lease Term, then either Landlord or Tenant shall
have the right to terminate this Lease (in whole if the damage extends to all of
the Premises or otherwise as to the affected portion of the Premises within the
Building) upon thirty (30) days prior written notice to the other, which
termination shall be effective on the thirtieth (30th) day after the other
party's receipt of such notice. Such notice must be delivered within thirty (30)
days after such casualty, or shall be deemed waived; provided, however, that
Tenant may revoke such termination notice, and require Landlord to restore the
Premises, by exercising any renewal option provided herein, if any.

         XV.  MACHINERY AND EQUIPMENT; ALTERATIONS AND ADDITIONS; REMOVAL OF
              FIXTURES.
<PAGE>   28
                  A. Tenant shall not place a load upon the floor of the
Premises which exceeds the maximum live load per square foot which Landlord (or
Landlord's architect or engineer) reasonably determines is appropriate for the
Building without Landlord's prior written consent. Tenant will not install or
operate in the Premises any electrical or other equipment requiring any changes,
replacements or additions to any base building system, without Landlord's prior
written consent, which shall not be unreasonably withheld, conditioned or
delayed (and if such consent is granted Tenant shall be responsible for the
costs of such changes, replacements or additions).

                  B. Tenant shall not make or allow to be made any alterations,
additions or improvements to or on the Premises which affect any structural or
building system components of the Premises or which, under applicable codes,
rules and/or regulations require any building electrical, plumbing or other
permit, without Landlord's prior written consent, which consent shall not be
unreasonably withheld, conditioned or delayed. Tenant shall have the right to
make any other alterations, repairs, additions or improvements in or to the
Premises without Landlord's prior written consent provided (i) the same do not
diminish the value of the Premises, and (ii) Tenant provides Landlord with prior
written notice thereof; provided, however that no exterior modification shall be
made in any event without Landlord's prior written consent in all cases. Any
such alterations, additions or improvements, including, but not limited to, wall
covering, paneling and built-in cabinet work, shall be made at Tenant's sole
expense (and, with respect to structural alterations, according to plans and
specifications approved in writing by Landlord), in compliance with all
applicable laws, by a licensed contractor, and in a good and workmanlike manner
conforming in quality and design with the Premises existing as of the
Commencement Date, shall not diminish the value of the Building or the Premises
and shall at once become a part of the realty and shall be surrendered with the
Premises (except as provided in Section 15.3, below). Tenant shall have the
right to use its own vendors to perform alterations to the Premises, subject to
Landlord's approval, which approval shall not be unreasonably withheld, in cases
where the underlying alteration requires Landlord's consent hereunder.

                  C. Upon the expiration or sooner termination of the Lease
Term, Tenant shall, at Tenant's sole expense, with due diligence, remove any
alterations, additions, or improvements made by Tenant which are designated by
Landlord to be removed at the time its consent to the installation thereof is
granted, and repair any damage to the Premises caused by such removal. Tenant
shall remove any of its movable property, trade fixtures and roof devices.
Tenant shall pay Landlord any damages for injury to the Premises or Building
resulting from such removal. All items of Tenant's personal property that are
not removed from the Premises or the Building by Tenant at the termination of
this Lease shall be deemed abandoned and become the exclusive property of
Landlord, without further notice to or demand upon Tenant. If the Premises are
not surrendered as and when aforesaid, Tenant shall indemnify Landlord against
all claims, losses, costs, expenses (including reasonable attorneys' fees) and
liabilities resulting from the delay by Tenant in so surrendering the same,
including without limitation any claims made by any succeeding occupant founded
on such delay. Tenant's obligations under these Sections 15.2 and 15.3 shall
survive the expiration or termination of this Lease.
<PAGE>   29
         XVI.   ACCEPTANCE OF PREMISES.

Landlord shall tender, and Tenant shall accept possession of, the Premises in
accordance with the terms of Exhibit C attached hereto. All provisions regarding
delivery of possession of the Premises, construction of leasehold improvements
to the Premises and any adjustments which may be made with respect to the
Commencement Date (as defined in Section 1.4) are set forth in Exhibit C.

         XVII.  TENANT IMPROVEMENTS.

The provisions governing initial improvements to be performed by Landlord or
Tenant to the Premises are set forth in Exhibit C hereto.

         XVIII. ACCESS.

18.1 Subject to the restrictions set forth below, Tenant shall permit Landlord
and its agents to enter the Premises at all reasonable times to inspect the
same; to show the Premises to prospective tenants, or interested parties such as
prospective lenders and purchasers; to exercise its rights under Section 48; to
clean, repair, alter or improve the Premises or the Building; to discharge
Tenant's obligations when Tenant has failed to do so within a reasonable time
after written notice from Landlord, subject to the express terms of this Lease;
to post notices of non-responsibility and similar notices and "For Sale" signs
and to place "For Lease" signs upon or adjacent to the Building or the Premises.
Tenant shall permit Landlord and its agents to enter the Premises at any time in
the event of an emergency. When reasonably necessary, Landlord may temporarily
close entrances, doors, corridors, elevators or other facilities without
liability to Tenant by reason of such closure. In exercising the foregoing
rights, Landlord shall use reasonable efforts to minimize any disruption to
Tenant's business. Landlord shall coordinate any entry, pursuant to the
foregoing, into the Premises with Tenant's facilities supervisor at least 24
hours in advance (except in cases of emergency involving fire or other casualty,
or other risk of injury or death to persons), and Landlord acknowledges that
Tenant may require Landlord and its agents to be accompanied by a representative
of Tenant for security purposes upon Landlord's entry to certain limited
portions of the Premises (other than in cases of emergency involving fire or
other casualty, or other risk of injury or death to persons) for legitimate,
documented security purposes. Tenant shall supply Landlord with telephone
numbers for Tenant's facilities supervisor so that Landlord will be able to
comply with established security procedures to the extent feasible under the
circumstances in the event Landlord requires immediate access to the Premises to
cure any emergency situation.

18.2 Landlord shall be excused from such of its obligations under this Lease as
are directly and materially impacted by the inability of Landlord to access the
Premises or any applicable part thereof due to Tenant's security restrictions,
if and to the extent the performance of such obligations was in fact hindered,
frustrated, or rendered impossible or impracticable due to the effect of such
restrictions on access.

         XIX.   MUTUAL WAIVER OF SUBROGATION.
<PAGE>   30
19.1 Tenant. Notwithstanding anything to the contrary in this Lease, whether the
loss or damage is due to the negligence of Landlord or Landlord's agents or
employees, or any other cause, Tenant hereby releases Landlord and Landlord's
agents and employees from responsibility for and waives its entire claim of
recovery for (i) any and all loss or damage to the personal property of Tenant
located in the Project, arising out of any of the perils which are covered by
Tenant's property insurance policy, with extended coverage endorsements which
Tenant is required to obtain under the applicable provisions of this Lease,
whether or not actually obtained, or (ii) loss resulting from business
interruption at the Premises, arising out of any of the perils which are or are
required to be covered by the business interruption insurance policy required to
be carried by Tenant under this Lease.

19.2 Landlord. Notwithstanding anything to the contrary in this Lease, whether
the loss or damage is due to the negligence of Tenant or Tenant's agents or
employees, or any other cause, Landlord hereby releases Tenant and Tenant's
agents and employees from responsibility for and waives its entire claim of
recovery for any and all loss or damage to the Building or any personal property
of Landlord located about the Project and the Building generally and all
property attached thereto (excluding any such property required to be insured by
Tenant hereunder), arising out of any of the perils which are covered by
Landlord's property insurance policy which Landlord is required to obtain under
the applicable provisions of this Lease, whether or not actually obtained.

19.3 Carriers. Landlord and Tenant shall each cause its respective insurance
carrier(s) to consent to such waiver of all rights of subrogation against the
other, and to issue an endorsement to all policies of insurance obtained by such
party confirming that the foregoing release and waiver will not invalidate such
policies.

         XX.  INDEMNIFICATION.

20.1 Subject to the provisions of Section 19 hereof and other provisions of this
Lease, Tenant shall indemnify and hold harmless Landlord, its agents, employees,
officers, directors, partners and shareholders from and against any and all
third party claims, liabilities, judgments, demands, causes of action, claims,
losses, damages, costs and expenses, including reasonable attorneys' fees and
costs, arising out of such third party claims, to the extent arising out of (i)
the use and occupancy of the Premises by Tenant, its officers, contractors,
licensees, agents, servants, employees, guests, invitees, visitors, assignees or
subtenants; (ii) the negligence or willful misconduct of Tenant, its officers,
contractors, licensees, agents, servants, employees, guests, invitees, visitors,
assignees or subtenants, in or about the Project; and/or (iii) any breach or
Default by Tenant under this Lease; provided that this indemnity shall not apply
to any loss, damage, liability or expense resulting from injuries to third
parties caused by the negligence or willful misconduct of Landlord, or its
officers, contractors, licensees, agents, employees or invitees (while within
the Premises).

20.2 The indemnifications set forth in this Section 20 shall survive termination
of this Lease.

         XXI. ASSIGNMENT AND SUBLETTING.
<PAGE>   31
         A. Consent Required. Except as specifically set forth herein to the
contrary, Tenant shall not assign, encumber, mortgage, pledge, license,
hypothecate or otherwise transfer the Premises or this Lease, or sublease all or
any part of the Premises, or permit the use or occupancy of the Premises by any
party other than Tenant, without the prior written consent of Landlord, in its
sole and absolute discretion.

         B. Procedure. Tenant must request Landlord's consent to such assignment
or sublease in writing at least fifteen (15) business days prior to the
commencement date of the proposed sublease or assignment, which written request
must include (a) the name and address of the proposed assignee or subtenant, (b)
the nature and character of the business of the proposed assignee or subtenant,
(c) financial information (including financial statements) of the proposed
assignee or subtenant, and (d) a copy of the proposed sublet or assignment
agreement. Tenant shall also provide any additional information Landlord
reasonably requests regarding such proposed assignment or subletting. Within ten
(10) days after Landlord receives Tenant's request (with all required
information included), Landlord shall, by written notice to Tenant, elect
either: (i) to grant its consent to such proposed assignment or subletting, or
(ii) to deny its consent to such proposed assignment or subletting, setting
forth with specificity the reason for such denial. If Landlord does not exercise
either of the above options within ten (10) business days after Landlord
receives Tenant's request, then Tenant may assign or sublease the Premises upon
the terms stated in Tenant's request.

         C. Conditions. Any subleases and/or assignments hereunder are also
subject to all of the following terms and conditions:

                  1. If Landlord approves an assignment or sublease as herein
provided (other than an assignment or sublease pursuant to Section 21.4 hereof),
Tenant shall pay to Landlord, as Additional Rent due under this Lease (which
amounts shall be due immediately upon receipt by Tenant), fifty percent (50%) of
the "Net Profits" (as defined below) generated from such transaction during each
Lease Year. For purposes hereof, the term "Net Profits" means: (i) with respect
to assignment, the amount paid by the assignee to acquire Tenant's rights under
the Lease, less (1) the portion of such sum fairly attributable to the
acquisition of Tenant's leasehold improvements or personal property which were
funded solely by Tenant, and (2) all reasonable and actual out-of-pocket
expenses incurred and paid by Tenant in procuring such assignment, including,
without limitation, brokerage fees, advertising costs, legal fees, allowances,
the cost of leasehold improvements and other concessions; and (ii) with respect
to a sublease, the amount, if any, by which the rent, any additional rent and
any other sums payable by the subtenant to Tenant under such sublease exceeds
the sum of (x) that portion of the Base Rent plus Additional Rent payable by
Tenant hereunder which is allocable to the portion of the Premises which is the
subject of such sublease, (y) all reasonable and actual out-of-pocket expenses
incurred by Tenant in procuring such sublease, including, without limitation,
brokerage fees, advertising costs, legal fees, allowances, the cost of leasehold
improvements and other concessions, and (z) the amortized costs of any leasehold
improvements or personal property provided as a part of such transaction and
existing prior to the commencement of the sublease term to the extent funded
solely by Tenant. The foregoing payments shall be made to Landlord by Tenant
immediately upon receipt of such sums by Tenant.
<PAGE>   32
                  2. No consent to any assignment or sublease shall constitute a
further waiver of the provisions of this Section, and all subsequent assignments
or subleases may be made only with the prior written consent of Landlord. In no
event shall any consent by Landlord be construed to permit reassignment or
resubletting by a permitted assignee or sublessee.

                  3. Tenant shall remain liable for all Lease obligations, all
of which shall be unaffected by any such sublease or assignment, and which Lease
obligations shall remain in full force and effect for all purposes. An assignee
of Tenant, at the option of Landlord, shall become directly liable to Landlord
for all obligations of Tenant hereunder, but no sublease or assignment by Tenant
shall relieve Tenant of any liability hereunder.

                  4. Any assignment or sublease without Landlord's prior written
consent shall be void, and shall, at the option of the Landlord, constitute a
Default under this Lease.

                  5. The term of any such assignment or sublease shall not
extend beyond the Lease Term. In no event will any assignee or subtenant (other
than pursuant to a transfer of the Lease within the scope of Section 21.4,
below) have the right to renew or extend the term of this Lease pursuant to
Section 51, below, which right shall be deemed personal to Tenant.

         21.3.6 Without limitation, it shall not be unreasonable for Landlord to
deny its consent to any proposed assignment or sublease if the proposed assignee
or subtenant fails to satisfy any one or more of the following criteria: (1) if
the proposed assignee or sublessee has a net worth such that Landlord determines
in its reasonable judgment that the proposed assignee or subtenant may be unable
to meet its financial and other obligations under this Lease after such
assignment or sublease; (2) if the proposed assignee or subtenant proposes to
use the Premises for a purpose which is not a permitted use hereunder; (3) if
the proposed assignee or subtenant has a history of landlord/tenant or
debtor/creditor problems (such as, but not limited to, defaults, evictions, or
other disputes) with Landlord, other landlords or other creditors; or (4)
Landlord determines, in its reasonable judgment, that the proposed
assignment/sublease documentation is not acceptable, and the proposed assignee
or subtenant has failed to cure same after reasonable notice by Landlord (not to
exceed ten [10] days in any event).

         A. Affiliated Entity; Sale of Business; Co-Location Agreements.
Notwithstanding anything to the contrary in this Lease, so long as such transfer
is not effectuated as part of a transaction or series of transfers orchestrated
in order to effect a transfer of this Lease (or Tenant's interest herein) in
isolation to Tenant's other leasehold interests and assets, Landlord's written
consent shall not be required for any sublease, assignment or other transfer of
this Lease to any other entity which (i) controls or is controlled by Tenant, or
(ii) is controlled by Tenant's parent company, or (iii) which purchases all or
substantially all of the assets of Tenant, or (iv) which purchases all or
substantially all of the ownership interests or stock of Tenant, provided,
however, that in each such event Tenant shall continue to remain fully liable
under the Lease, on a joint and several basis with the assignee or acquiror of
such assets or stock. Tenant shall be required to give Landlord at least thirty
(30) days written notice in advance of any such sublease or
<PAGE>   33
assignment, except with respect to transfers by operation of law occasioned
through a sale of publicly traded shares in Tenant. Further and in addition to
the foregoing, notwithstanding anything to the contrary in this Lease, Tenant
shall not be prohibited by this Section 21 from entering into agreements with
Tenant's customers, in the ordinary course of Tenant's business, pursuant to
which Tenant permits such customers to locate equipment within the Premises;
provided however that in any such event no such customers shall be deemed to be
in privity with Landlord hereunder, nor shall any such parties be considered
third party beneficiaries of any of the rights of Tenant hereunder.

         XXII.  ADVERTISING.

Tenant shall not display any sign, graphics, notice, picture, or poster, or any
advertising matter whatsoever, anywhere in or about the Premises or the Building
at places visible from anywhere outside or at the entrance to the Premises
without first obtaining Landlord's written consent thereto, which Landlord may
grant or withhold in its sole discretion; provided, however that Landlord's
consent to a proposal by Tenant to install logo signage in the reception area of
the Premises shall not be unreasonably withheld, conditioned or delayed. Tenant
shall be responsible to maintain any permitted signs and remove the same at
Lease termination. If Tenant shall fail to do so, Landlord may do so at Tenant's
cost. Tenant shall be responsible to Landlord for any damage caused by the
installation, use, maintenance or removal of any such signs.

         XXIII. LIENS.

Tenant shall keep the Premises and the Building free from any liens arising out
of any work performed, materials ordered or obligations incurred by or on behalf
of Tenant, and Tenant hereby agrees to indemnify and hold Landlord, its agents,
employees, independent contractors, officers, directors, partners, and
shareholders harmless from any liability, cost or expense (including attorneys'
fees and defense costs) for or arising from such liens. Tenant shall cause any
such lien imposed to be released of record by payment or posting of the proper
bond acceptable to Landlord within twenty (20) days after written request by
Landlord. Tenant shall give Landlord written notice of Tenant's intention to
perform work on the Premises which might result in any claim of lien at least
ten (10) days prior to the commencement of such work to enable Landlord to post
and record a Notice of Nonresponsibility or other notice deemed proper before
commencement of any such work. If Tenant fails to remove any lien within the
prescribed twenty (20) day period, then Landlord may do so at Tenant's expense
and Tenant's reimbursement to Landlord for such amount, including reasonable
attorneys' fees and costs, shall be deemed Additional Rent hereunder.

         XXIV. DEFAULT.

         A. Tenant's Default. A "Default" under this Lease by Tenant shall exist
if any of the following occurs (taking into account the expiration of the notice
and cure periods provided for below):

                  1. If Tenant fails to pay Base Rent, Additional Rent or any
other sum required to be paid hereunder within five (5) days after written
notice from Landlord that such payment was due, but was not paid as of the due
date (provided, however, if Landlord
<PAGE>   34
has delivered two (2) such notices to Tenant within the prior twelve (12) month
period, any subsequent failure to pay Base Rent, Additional Rent or any other
sum required to be paid to Landlord hereunder on or before the due date for such
payment occurring shall constitute a Default by Tenant without requirement of
such five (5) day notice and opportunity to cure; but in the event a full year
elapses between such failures then Tenant shall again have the right to such
cure period); or

                  2. If Tenant fails to perform any term, covenant or condition
of this Lease except those requiring the payment of money to Landlord as set
forth in Section 24.1.1 above, and Tenant fails to cure such breach within
thirty (30) days after written notice from Landlord where such breach could
reasonably be cured within such thirty (30) day period; provided, however, that
where such failure could not reasonably be cured within the thirty (30) day
period, that Tenant shall not be in Default if it commences such performance
promptly after its receipt of Landlord's written notice and diligently
thereafter prosecutes the same to completion; provided that no such grace period
to be permitted in the event of any one or more of the following: (i) the
Default relates to the maintenance of insurance obligations, (ii) the Default
relates to the assignment and subletting provisions, (iii) the Default relates
to a violation of Section 5.2 of this Lease, (iv) the Default is of a nature as
set forth in Section 24.1.3, in which event the periods set forth therein shall
control, or Section 24.1.4, in which event there shall be no applicable cure
period, or (v) there exists a reasonable possibility of danger to the health or
safety of the Landlord, the Tenant, Tenant's invitees, or any other occupants
of, or visitors to, the Building; or

                  3. If Tenant shall (i) make an assignment for the benefit of
creditors, (ii) acquiesce in a petition in any court in any bankruptcy,
reorganization, composition, extension or insolvency proceedings, (iii) seek,
consent to or acquiesce in the appointment of any trustee, receiver or
liquidator of Tenant and of all or substantially all of Tenant's property, (iv)
file a petition seeking an order for relief for the benefit of Tenant under the
Bankruptcy Code, as now or hereafter amended or supplemented, or by filing any
petition under any other present or future federal, state or other statute or
law for the same or similar relief, or (v) fail to win the dismissal,
discontinuation or vacating of any involuntary bankruptcy proceeding filed
against Tenant within sixty (60) days after such proceeding is initiated; or

     24.1.4 If Tenant shall have abandoned or vacated the Premises or any
material (i.e., in excess of 30%) portion thereof.

         A. Remedies. Upon a Default, Landlord shall have the following
remedies, in addition to all other rights and remedies provided by law or
available in equity or otherwise provided in this Lease, any one or more of
which Landlord may resort to cumulatively, consecutively, or in the alternative:

                  1. Landlord may continue this Lease in full force and effect,
and this Lease shall continue in full force and effect as long as Landlord does
not terminate this Lease, and Landlord shall have the right to collect Base
Rent, Additional Rent and other charges when due.
<PAGE>   35
                  2. Landlord may terminate this Lease, or may terminate
Tenant's right to possession of the Premises, at any time by giving written
notice to that effect, in which event Landlord covenants to use commercially
reasonable efforts to relet the Premises or any part thereof and mitigate its
damages, as more fully set forth herein. Upon the giving of a notice of the
termination of this Lease, this Lease (and all of Tenant's rights hereunder)
shall immediately terminate, provided that, without limitation, Tenant's
obligation to pay Base Rent, Additional Rent, and any damages otherwise payable
under this Section 24, shall survive such termination and shall not be
extinguished thereby. Upon the giving of a notice of the termination of Tenant's
right of possession, all of Tenant's rights in and to possession of the Premises
shall terminate but this Lease shall continue subject to the effect of this
Section 24. Upon either such termination, Tenant shall surrender and vacate the
Premises in the condition required by Section 26, and Landlord may re-enter
(provided it can do so without breach of peace) and take possession of the
Premises and all the remaining improvements or property and eject Tenant or any
of the Tenant's subtenants, assignees or other person or persons claiming any
right under or through Tenant or eject some and not others or eject none. This
Lease may also be terminated by a judgment specifically providing for
termination. Any termination under this Section shall not release Tenant from
the payment of any sum then due Landlord or from any claim for damages or Base
Rent, Additional Rent or other sum previously accrued or thereafter accruing
against Tenant, all of which shall expressly survive such termination. Reletting
may be for a period shorter or longer than the remaining Lease Term. No act by
Landlord other than giving written notice to Tenant shall terminate this Lease.
Acts of maintenance, efforts to relet the Premises or the appointment of a
receiver on Landlord's initiative to protect Landlord's interest under this
Lease shall not constitute a constructive or other termination of Tenant's right
to possession or of this Lease, either of which may be effected solely by an
express written notice from Landlord to Tenant. On termination, Landlord shall
have the right to remove all Tenant's personal property and store same at
Tenant's cost, and to recover from Tenant as damages:

                  a) The worth at the time of award of unpaid Base Rent,
Additional Rent and other sums due and payable which had been earned at the time
of termination; plus

                  b) The worth at the time of award of the amount by which the
unpaid Base Rent, Additional Rent and other sums due and payable which would
have been payable after termination for the balance of the Lease Term exceeds
the fair rental value of the Premises for the balance of the Term; plus

                  c) Any other amount necessary to compensate Landlord for all
of the out-of-pocket costs incurred on account of Tenant's failure to perform
Tenant's obligations under this Lease, including, without limitation, any costs
or expenses reasonably incurred by Landlord: (i) in retaking possession of the
Premises; (ii) in maintaining, repairing, preserving, restoring, replacing,
cleaning, altering or rehabilitating the Premises or a portion thereof,
including such acts for reletting to a new tenant or tenants; (iii) for leasing
commissions; or (iv) for any other costs necessary or appropriate to relet the
Premises. To the extent any of such costs are incurred in connection with a
lease transaction having a term in excess of the remaining Term hereof, all of
the foregoing costs incurred in connection therewith shall be amortized on a
straight-line basis over the term of such new lease, assuming equal monthly
installments of principal and interest, at an interest rate of twelve
<PAGE>   36
percent (12%), and Tenant's liability shall be limited to the amortized portion
of the same (i.e., the monthly payments as so determined) falling within the
Term hereof.

                  d) The "worth at the time of award" of the amounts referred to
in Section 24.2.2.1 is computed by allowing interest at the Default Rate through
the date of payment. The "worth at the time of award" of the amounts referred to
in Section 24.2.2.2 shall be computed by discounting the same to present value
using the Discount Rate. In lieu of the amounts recoverable by Landlord pursuant
to Section 24.2.2.2, above, but in addition to the amounts specified in Section
24.2.2.1 and 24.2.2.3 (or any other portion of this Section 24), Landlord may,
at its sole election, recover "Indemnity Payments," as defined hereinbelow, from
Tenant. For purposes of this Lease "Indemnity Payments" means an amount equal to
the Base Rent, Additional Rent and other payments provided for in this Lease
which would have become due and owing hereunder from time to time during the
unexpired Lease Term after the effective date of the termination, but for such
termination, less the Base Rent, Additional Rent and other payments, if any,
actually collected from Tenant or others, by Landlord and allocable to the
Premises. If Landlord elects to pursue Indemnity Payments as set forth above,
Tenant shall, on demand, make Indemnity Payments monthly, and Landlord may sue
for all Indemnity Payments at any time after they accrue, either monthly, or at
less frequent intervals. Tenant further agrees that Landlord may bring suit for
Indemnity Payments and/or any other damages recoverable herein at or after the
end of the Lease Term as originally contemplated under this Lease, and Tenant
agrees that, in such event, Landlord's cause of action to recover the Indemnity
Payments shall be deemed to have accrued on the last day of the Lease Term as
originally contemplated. In seeking any new tenant for the Premises, Landlord
shall be entitled to grant any reasonable concessions. In no event shall Tenant
be entitled to any excess of any rental obtained by reletting over and above the
rental herein reserved. To the fullest extent permitted by law, Tenant waives
redemption or relief from forfeiture under any other present or future law, in
the event Tenant is evicted or Landlord takes possession of the Premises by
reason of any Default of Tenant hereunder.

                  3. Landlord may, with or without terminating this Lease,
re-enter the Premises pursuant to judicial process (except in the event of
Tenant's abandonment of the Premises in which event no judicial process shall be
required) and remove all persons and property from the Premises; such property
may be removed and stored in a public warehouse or elsewhere at the cost of and
for the account of Tenant. No re-entry or taking possession of the Premises by
Landlord pursuant to this Section shall be construed as an election to terminate
this Lease unless a written notice of such intention is given to Tenant, or
possession of the Premises is assumed by a new tenant, in which event Tenant's
liability is mitigated by the amount of rent actually received by Landlord from
such other tenant, less the actual costs incurred by Landlord in obtaining such
new tenant; including, but not limited to market based brokerage fees, legal
fees, tenant improvement costs, lease concessions and any other cost.

                  4. Tenant, on its own behalf and on behalf of all persons
claiming through or under Tenant, including all creditors, does hereby
specifically waive and surrender any and all rights and privileges, so far as is
permitted by law, which Tenant and all such persons might otherwise have under
any present or future law (1) except as may be otherwise specifically required
herein, to the service of any notice to quit or of Landlord's intention to
<PAGE>   37
re-enter or to institute legal proceedings, which notice may otherwise be
required to be given, (2) to redeem the Premises, (3) to re-enter or repossess
the Premises, (4) to restore the operation of this Lease, with respect to any
dispossession of Tenant by judgment or warrant of any court or judge, or any
re-entry by Landlord, or any expiration or termination of this Lease, whether
such dispossession, re-entry, expiration or termination shall be by operation of
law or pursuant to the provisions of this Lease, (5) to the benefit of any law
which exempts property from liability for debt or for distress for rent or (6)
to a trial by jury in any claim, action proceeding or counter-claim arising out
of or in any way connected with this Lease.

     24.2.5 In the event of termination of this Lease or repossession of the
Premises after a Default, Landlord agrees to use commercially reasonable efforts
to mitigate its damages and relet the Premises after any termination of this
Lease or Tenant's right to possession of the Premises hereunder, provided that
(i) (if applicable) Landlord shall not be obligated to show preference for
reletting the Premises over any other vacant space in the Project, (ii) Landlord
shall have the right (but not the obligation) to divide the Premises, or to
consolidate portions of the Premises with other spaces, in order to facilitate
such reletting, as Landlord deems appropriate, (iii) Landlord shall not have any
obligation to use efforts other than commercially reasonable efforts under the
circumstances to collect rental after any such reletting, and (iv) Landlord may
relet the whole or any portion of the Premises for any period, to any tenant,
and for any use and purpose, upon such terms as it deems appropriate, and may
grant any rental or other lease concessions as it deems advisable, including
free rent. In any dispute regarding whether Landlord has met its obligation to
use commercially reasonable efforts to mitigate its damages hereunder, Tenant
shall have the burden of proving, by clear and convincing evidence, that
Landlord has failed to do so. In no event shall Tenant be entitled to any excess
of any rental obtained under this Section 24.2.5 by reletting over and above the
Base Rent and Additional Rent herein reserved.

         XXV. SUBORDINATION.

25.1 Subordination. This Lease shall at all times be and remain subject and
subordinate to the lien of any mortgage, deed of trust, ground lease or
underlying lease now or hereafter in force against the Premises, and to all
advances made or hereafter to be made upon the security thereof. Tenant shall
execute and return to Landlord any customary documentation requested by Landlord
in order to confirm the foregoing subordination within ten (10) days after
Landlord's written request. In the event any proceedings are brought for
foreclosure, or in the event of the exercise of the power of sale under any
mortgage or deed of trust made by the Landlord covering the Premises, Tenant
shall attorn to the purchaser at any such foreclosure, or to the grantee of a
deed in lieu of foreclosure, and recognize such purchaser or grantee as the
Landlord under this Lease. Tenant agrees that no mortgagee or successor to such
mortgagee shall be (i) bound by any payment of Base Rent or Additional Rent for
more than one (1) month in advance, (ii) bound by any amendment or modification
of this Lease made without the consent of Landlord's mortgagee or such successor
in interest, (iii) liable for damages for any breach, act or omission of any
prior landlord, or (iv) subject to any claim of offset or defenses that Tenant
may have against any prior landlord; provided that such mortgagee or successor
shall not be relieved of the obligation to comply with all of the Landlord's
obligations under the Lease accruing from and after the date such mortgagee or
successor takes title to the Project, irrespective of whether the original
non-compliance with any such obligation arose prior to and is continuing as of
such date, or arose on or after
<PAGE>   38
such date (provided however that if such obligation arose prior to the date such
mortgagee or successor took title to the Project, such mortgagee or successor
shall not be deemed in default until after the provision of any notice of
default required by this Lease to such mortgagee or successor, and its failure
to cure same within the cure period provided for herein).

25.2 Non-Disturbance Agreement. Landlord agrees to use good faith efforts to
obtain a Subordination, Non-Disturbance and Attornment Agreement from any
present (if any) or future mortgagee for the Building in a form to be negotiated
between Landlord, Tenant and the applicable mortgagee or deed of trust holder,
using such mortgagee's standard form, and approval of which by Tenant and
Landlord shall not be unreasonably withheld, conditioned or delayed (as
reasonably approved by Landlord, Tenant and such Mortgagee, an "SNDA"),
providing, inter alia, (i) for the subordination of this Lease to such mortgage,
(ii) for the attornment of Tenant to Landlord's successor in title, and (iii)
that, as long as Tenant is not in default hereunder beyond any applicable notice
and cure period, Tenant's right of possession and other leasehold rights shall
not be disturbed in the event of a foreclosure of such mortgage. Upon obtaining
such SNDA from such mortgagee, Tenant agrees to promptly execute and deliver
such SNDA to Landlord. Notwithstanding the foregoing, Landlord's ability to
obtain an SNDA shall not be a condition hereof, and the failure of Landlord to
obtain an SNDA shall not be deemed a default by Landlord hereunder or entitle
Tenant to exercise any remedial action.

         XXVI. SURRENDER OF POSSESSION.

Upon expiration of the Lease Term, Tenant shall promptly and peacefully
surrender the Premises to Landlord in as good condition as when received by
Tenant from Landlord or as thereafter improved, reasonable use and wear and tear
and damage by fire, casualty and condemnation excepted. If the Premises are not
surrendered in accordance with the terms of this Lease, Tenant shall indemnify
Landlord and its agents, employees, independent contractors, officers,
directors, partners, and shareholders against any loss or liability including
reasonable attorneys' fees and costs, and including liability to succeeding
tenants, resulting from delay by Tenant in so surrendering the Premises. This
indemnification shall survive termination of this Lease.

         XXVII. NON-WAIVER.

Waiver by Landlord of any breach of any term, covenant or condition herein
contained shall not be deemed to be a waiver of such term, covenant, or
condition(s), or any subsequent breach of the same or any other term, covenant
or condition of this Lease, other than the failure of Tenant to pay the
particular rental so accepted, regardless of Landlord's knowledge of such
preceding breach at the time of acceptance of such Base Rent.

         XXVIII. HOLDOVER.

If Tenant shall, without the written consent of Landlord, hold over after the
expiration of the Lease Term, Tenant shall be deemed a tenant at sufferance,
which tenancy may be terminated as provided by applicable state law. During any
holdover tenancy (whether or not consented to by Landlord), unless Landlord has
otherwise agreed in writing, Tenant agrees to pay to Landlord, a per diem
occupancy charge equal to one hundred fifty percent (150%) of the per
<PAGE>   39
diem Base Rent and Additional Rent as was in effect under this Lease for the
last month of the Lease Term. Such payments shall be made within five (5) days
after Landlord's demand, and in no event less often than once per month (in
advance). In the case of a holdover which has been consented to by Landlord,
unless otherwise agreed to in writing by Landlord and Tenant, Tenant shall give
to Landlord thirty (30) days prior written notice of any intention to quit the
Premises, and Tenant shall be entitled to thirty (30) days prior written notice
to quit the Premises, except in the event of non-payment of Base Rent or
Additional Rent in advance or the breach of any other covenant or the existence
of a Default. Upon expiration of the Lease Term as provided herein, Tenant shall
not be entitled to any notice to quit, the usual notice to quit being hereby
expressly waived under such circumstances, and Tenant shall surrender the
Premises on the last day of the Lease Term as provided in Section 26, above.

         XXIX. CONDEMNATION.

29.1 Definitions. The terms "eminent domain", "condemnation", and "taken", and
the like in this Section 29 include takings for public or quasi-public use, and
sales under threat of condemnation and private purchases in place of
condemnation by any authority authorized to exercise the power of eminent
domain. 

29.2 Taking. If the whole of the Premises is taken, either permanently or
temporarily, by eminent domain or condemnation, this Lease shall automatically
terminate as of the date title vests in the condemning authority, and Tenant
shall pay all Base Rent, Additional Rent, and other payments up to that date. If
twenty percent (20%) or more of the Premises is permanently taken, or if access
to the Tenant is, by virtue of a taking, permanently denied or materially
adversely affected, by eminent domain or condemnation, then Landlord or Tenant
shall have the right (to be exercised by written notice to the other within
sixty (60) days after receipt of notice of said taking) to terminate this Lease
from the date when possession is taken thereunder pursuant to such proceeding or
purchase. If neither party elects to terminate this Lease, as aforesaid, then
Landlord shall within a reasonable time after title vests in the condemning
authority, repair and restore, at Landlord's expense, the portion not taken so
as to render same into an architectural whole to the fullest extent reasonably
possible, and, if any portion of the Premises is taken, thereafter the Base Rent
shall be reduced (on a per square foot basis) in proportion to the portion of
the Premises taken. If there is a temporary taking involving the Premises or
Building, if a taking of other portions of the Building or Common Areas does not
deny Tenant access to and continued use (in the same manner as prior to the
taking) of the Building and Premises, or if less than twenty percent (20%) of
the Premises is permanently taken by eminent domain or condemnation and does not
deny Tenant access to and continued use of the Building and Premises, then this
Lease shall not terminate, and Landlord shall repair and restore, at its own
expense, the portion not taken so as to render same into an architectural whole
to the fullest extent reasonably possible, and, if any portion of the Premises
was taken, thereafter the Base Rent shall be reduced (on a per square foot
basis) in proportion to the portion of the Premises taken.

29.3 Award. Except as set forth below, Landlord reserves all rights to damages
to the Premises or arising out of the loss of any leasehold interest in the
Premises created hereby, arising in connection with any partial or entire taking
by eminent domain or condemnation. Tenant hereby assigns to Landlord any right
Tenant may have to such damages or award, and Tenant shall make no claim against
Landlord or the condemning authority for damages for termination of Tenant's
leasehold interest or for interference with Tenant's business as a result 
<PAGE>   40
of such taking. The foregoing notwithstanding, Tenant shall have the right to
claim and recover from the condemning authority compensation for any loss which
Tenant may incur for Tenant's moving expenses, business interruption or taking
of Tenant's personal property (but specifically excluding any leasehold interest
in the Building or Premises) under the then applicable law provided that Tenant
shall not make any claim that will detract from or diminish any award for which
Landlord may make a claim.

         XXX. NOTICES.

All notices and demands which may be required or permitted to be given to either
party hereunder shall be in writing, and shall be delivered personally or sent
by United States certified mail, postage prepaid, return receipt requested, or
by Federal Express or other reputable overnight carrier, to the addresses set
out in Section 1.7, and to such other person or place as each party may from
time to time designate in a notice to the other. Notice shall be deemed given
upon the earlier of actual receipt or refusal of delivery.

         XXXI. MORTGAGEE PROTECTION.

Tenant agrees to give any mortgagee(s) and/or trust deed holder(s), by
registered mail, a copy of any notice of default served upon the Landlord,
provided that prior to such notice Tenant has been notified in writing (by way
of notice of assignment of rents and leases, or otherwise) of the addresses of
such mortgagee(s) and/or trust deed holder(s). Tenant further agrees that if
Landlord shall have failed to cure such default within the time provided for in
this Lease, then the mortgagee(s) and/or trust deed holder(s) shall have an
additional thirty (30) days within which to cure such default or if such default
cannot be cured within that time, then such additional time as may be necessary
if within such thirty (30) days any mortgagee and/or trust deed holder(s) has
commenced and is diligently pursuing the remedies necessary to cure such
default, during which time Tenant shall not have the right to pursue any claim
against Landlord, such mortgagee and/or such trust deed holder(s), including but
not limited to any claim of actual or constructive eviction.

         XXXII. COSTS AND ATTORNEYS' FEES.

In any litigation between the parties arising out of this Lease, and in
connection with any consultations with counsel and other actions taken or
notices delivered, in relation to a default by any party to this Lease, the
non-prevailing party shall pay to the prevailing party all reasonable expenses
and court costs including attorneys' fees incurred by the prevailing party, in
preparation for and (if applicable) at trial, and on appeal. Such attorney's
fees and costs shall be payable upon demand.

         XXXIII. BROKERS.

Tenant represents and warrants to Landlord that neither it nor its officers or
agents nor anyone acting on its behalf has dealt with any real estate broker
other than Trammell Crow Real Estate Services, Inc. (on behalf of Landlord) and
Julien J. Studley, Inc. (on behalf of Tenant) in the negotiating or making of
this Lease, both of which shall be paid a fee by Landlord, pursuant to separate
written agreement, upon the consummation of this Lease. Tenant agrees to
indemnify and hold Landlord, its agents, employees, partners, directors,
<PAGE>   41
shareholders and independent contractors harmless from all liabilities, costs,
demands, judgments, settlements, claims and losses, including reasonable
attorney's fees and costs, incurred by Landlord in conjunction with any such
claim or claims of any other broker or brokers claiming to have interested
Tenant in the Building or Premises or claiming to have caused Tenant to enter
into this Lease. Landlord represents that it has not dealt with any brokers
other than the parties listed above in negotiating and entering into this Lease
and shall indemnify, defend and hold Tenant harmless from any breach of the
foregoing representation and warranty.

         XXXIV. LANDLORD'S LIABILITY.

         Anything in this Lease to the contrary notwithstanding, covenants,
undertakings and agreements herein made on the part of Landlord, are made and
intended not for the purpose of binding Landlord personally or the assets of
Landlord but are made and intended to bind only Landlord's interest in the
Premises and Building, as the same may, from time to time, be encumbered; no
personal liability shall at any time be assumed by or asserted or enforceable
against Landlord or any member, manager, officer, employee, agent, trustee,
beneficiary, or individual partner of Landlord or of any member, manager,
officer, employee, agent, trustee, beneficiary, or individual partner of
Landlord, or any of their respective heirs, legal representatives, successors
and assigns on account of this Lease or on account of any covenant, undertaking
or agreement of Landlord in this Lease or any claim made against Landlord under
this Lease; and Tenant agrees to look solely to the interests of Landlord in the
Premises and the Building for the enforcement of any claims against Landlord
arising hereunder. Any and all personal liability, if any, beyond that which may
be asserted under this Section 34 is hereby expressly waived and released by
Tenant and by all persons claiming by, through, or under Tenant. In addition, in
no event shall Landlord be in default of this Lease unless Tenant notifies
Landlord of the precise nature of the alleged breach by Landlord, and Landlord
fails to cure such breach within fifteen (15) days after the date of Landlord's
receipt of such notice or refusal of delivery (provided that if the alleged
breach is of such a nature that it cannot reasonably be cured within such
fifteen (15) day period, then Landlord shall not be in default if Landlord
commences a cure within such fifteen (15) day period and diligently thereafter
prosecutes such cure to completion). In no event shall Tenant have any right to
terminate this Lease by virtue of any uncured default by Landlord.

         XXXV. ESTOPPEL CERTIFICATES.

Tenant shall, from time to time, within ten (10) business days of Landlord's
written request, execute, acknowledge and deliver to Landlord or its designee a
written statement stating: the date the Lease was executed and the date it
expires; the date the Tenant entered occupancy of the Premises; the amount of
Base Rent, Additional Rent and other charges due hereunder and the date to which
such amounts have been paid; that this Lease is in full force and effect and has
not been assigned, modified, supplemented or amended in any way (or specifying
the date and terms of any agreement so affecting this Lease); that this Lease
represents the entire agreement between the parties as to this leasing; that all
conditions under this Lease to be performed by the Landlord have been satisfied
(or specifying any such conditions that have not been satisfied); that all
required contributions by Landlord to Tenant on account of Tenant's improvements
have been received (or specifying any such contributions that have not been
received); that to Tenant's knowledge, following reasonable investigation and
<PAGE>   42
inquiry, there are no existing defenses or offsets which the Tenant has against
the enforcement of this Lease by the Landlord; that no Base Rent or Additional
Rent has been paid more than one (1) month in advance; that no security has been
deposited with Landlord (or, if so, the amount thereof) other than the Security
Deposit; or any other customary factual matters evidencing the status of the
Lease, as may be reasonably required either by a lender making a loan to
Landlord to be secured by a deed of trust or mortgage against the Building, or a
purchaser of the Building, which written statement shall, to the extent the
certifications required to be made therein are true and correct as of such time,
be in substantially the same form as Exhibit F attached hereto and made a part
hereof by this reference. It is intended that any such statement delivered
pursuant to this paragraph may be relied upon by a prospective purchaser of
Landlord's interest or a mortgagee of Landlord's interest or assignee of any
mortgage upon Landlord's interest in the Building. If Tenant fails to respond
within ten (10) business days after receipt by Tenant of a written request by
Landlord as herein provided, Tenant shall be deemed to have given such
certificate as above provided without modification and shall be deemed to have
admitted the accuracy of any information supplied by Landlord to a prospective
purchaser or mortgagee consistent with the terms of the estoppel so requested.

Landlord shall, from time to time, within ten (10) business days of Tenant's
written request, execute, acknowledge and deliver to Tenant or its designee a
written statement stating: the date the Lease was executed and the date it
expires; the date the Tenant entered occupancy of the Premises; the amount of
Base Rent, Additional Rent and other charges due hereunder and the date to which
such amounts have been paid; that this Lease is in full force and effect and has
not been assigned, modified, supplemented or amended in any way (or specifying
the date and terms of any agreement so affecting this Lease); that this Lease
represents the entire agreement between the parties as to this leasing; that all
conditions under this Lease to be performed by the Tenant have been satisfied
(or specifying any such conditions that have not been satisfied); that to
Landlord's knowledge, there are no defaults by Tenant under this Lease.

         XXXVI. FINANCIAL REPRESENTATIONS AND INFORMATION.

         Tenant has provided Landlord prior to the date hereof with the
information regarding Tenant's net asset value and financial condition that is
attached as Exhibit G hereto and made a part hereof. Tenant represents that the
information contained in Exhibit G is true, correct and complete, and
acknowledges that Landlord is relying thereupon (without additional
investigation) in entering into this Lease with Tenant. Tenant shall deliver to
Landlord updated information, using the same format (and containing not less
than the same level of detail) set forth in Exhibit G, certified by Tenant's
chief financial officer as true, correct and complete as of the date made,
within ten (10) business days after Landlord's written request (which shall be
limited to one (1) request per calendar quarter during the Lease Term). In the
event Tenant ever provides to any creditor of Tenant's (including but not
limited to lenders, other landlords and/or judgment creditors) formal financial
statements regarding Tenant (including but not limited a detailed balance sheet,
a profit and loss statement, and/or a cash flow statement), whether or not
audited by an independent certified public accountant, Tenant agrees to provide
the same information to Landlord, within ten (10) business days after
<PAGE>   43
Landlord's written request (which shall be limited to one (1) request per
calendar quarter during the Lease Term).

Within ten (10) days after Landlord's request, Tenant shall deliver to Landlord
a year-to-date financial statement of Tenant for Tenant's current fiscal year
and annual financial statements for the two (2) fiscal years prior to Tenant's
current fiscal year, which financial statements shall be prepared by a certified
public accountant in accordance with generally accepted accounting principles
consistently applied and include a balance sheet and profit and loss statement
and which annual financial statements shall be audited by a certified public
accountant. In the event that Tenant does not produce nor possess financial
statements, Tenant shall deliver to Landlord, in lieu of financial statements,
internal balance sheets, the accuracy of which shall have been certified to by
the president, a vice president, the treasurer or assistant treasurer of Tenant.
Such certifications shall specifically state that the balance sheets are
accurate and full representations of the financial condition of Tenant. To the
extent tenant is not a publicly traded company, Landlord agrees that it shall
use reasonable efforts to maintain the confidentiality of Tenant's financial
information; provided, however that Landlord shall be permitted to disclose same
to Landlord's lenders, prospective purchasers, and investors.

         XXXVII. TRANSFER OF LANDLORD'S INTEREST.

In the event of any transfer(s) of Landlord's interest in the Premises or the
Building to a bona-fide third-party purchaser, other than a transfer for
security purposes only, upon the assumption of this Lease by the transferee, the
transferor shall be automatically relieved of any and all obligations and
liabilities on the part of Landlord accruing from and after the date of such
transfer, and Tenant agrees to attorn to the transferee.

         XXXVIII. RIGHT TO PERFORM.

If Tenant shall fail to pay any sum of money, other than Base Rent and
Additional Rent, required to be paid by it hereunder or shall fail to perform
any other act on its part to be performed hereunder, and (except in the event of
emergency in which case no grace or cure period shall be applicable or required)
such failure shall continue for ten (10) days after notice to Tenant (or such
other cure period as may be provided for herein), Landlord may, but shall not be
obligated so to do, and without waiving or releasing Tenant from any obligations
of Tenant, make any such payment or perform any such other act on Tenant's part
to be made or performed as provided in this Lease. Landlord shall have (in
addition to any other right or remedy of Landlord) the same rights and remedies
in the event of the nonpayment of sums due under this section as in the case of
Default by Tenant in the payment of Base Rent. All sums paid by Landlord and all
penalties, interest and costs in connection therewith, shall be due and payable
by Tenant upon written demand within ten (10) business days after such payment
by Landlord, together with interest thereon at the Default Rate from such date
to the date of payment.

         XXXIX. COMMON AREAS
<PAGE>   44

For purposes hereof, the term "Common Areas" shall mean (i) all portions of the
Land other than portions upon which the Building is situated, including
landscaped areas and the like, as the same may be modified from time to time by
Landlord; (ii) all loading docks, corridors, lobbies, elevator cabs, stairs and
other portions of the Building that would customarily be made available to
tenants of the Building, as the same may be modified from time to time by
Landlord; (iii) any parking deck, parking structure, or surface parking
facility, and any connector from the Building thereto; and (iv) any areas which
are common areas for, on, or utilized in general by tenants, owners and/or
occupants of the complex.

         XD. SALES AND AUCTIONS.

Tenant may not display or sell merchandise outside the exterior walls and
doorways of the Premises and may not use such areas for storage. Tenant shall
not conduct or permit to be conducted any sale by auction in, upon or from the
Premises whether said auction be voluntary, involuntary, pursuant to any
assignment for the payment of creditors or pursuant to any bankruptcy or other
insolvency proceedings.

         XDI. ACCESS TO ROOF.

41.1 Subject to (i) compliance with all rules, regulations, proffers, statutes
and codes of any governmental authority having jurisdiction thereover, and (ii)
subject to Landlord's prior written consent, which consent shall not be
unreasonably withheld, conditioned or delayed, Tenant shall have the right of
access to and non-exclusive use of the roof of the Building for the installation
of various communication equipment (Tenant's "Roof Use"); provided further that
such installation and the Roof Use shall not void any roof or other warranty
applicable to the Building and that all such installations shall be located and
screened in a manner mutually acceptable to both Landlord and Tenant.

41.2 If the rate of any insurance carried by Landlord is increased as a result
of Tenant's Roof Use, then Tenant will pay to Landlord within ten (10) days
before the date Landlord is obligated to pay a premium on the insurance (or
within ten (10) days after Landlord delivers to Tenant a certified statement
from Landlord's insurance carrier stating that the rate increase was caused by
Tenant's Roof Use, whichever date is later), a sum equal to the difference
between the original premium and the increased premium resulting from the Roof
Use.

41.3 Landlord has not made any representations or promises pertaining to the
suitability of the Building's rooftop for the Roof Use. Tenant, for the purpose
of this paragraph and its right to rooftop access hereunder, accepts the rooftop
in its "as is" condition.

41.4 Tenant will obtain prior to installation, any and all necessary licenses,
approvals, permits, etc., necessary for the installation, maintenance and use of
any equipment installed pursuant to this Section 41. Tenant's Roof Use shall not
in any way conflict with any applicable law, statute, proffer, ordinance or
governmental rules or regulation now in force or which may hereafter be enacted.
The Tenant will, at its sole cost and expense, promptly comply or ensure that
the Building complies with all laws, statutes, proffers, ordinances,
<PAGE>   45
governmental rules or regulations, or requirements of any board of fire
insurance underwriters or other similar bodies now or hereafter constituted
relating to or affecting Tenant's Roof Use. Tenant shall indemnify and hold
Landlord harmless from and against any and all loss, cost (including reasonable
attorney's fees incurred in defending Landlord), damage or liability arising out
of any violations of said laws, statutes, proffers, ordinances rule or
regulations.

41.5 Tenant's Roof Use shall be exercised: (1) in such manner as will not create
any hazardous condition or interfere with or impair the operation of the
heating, ventilation, air conditioning, plumbing, electrical, fire protection,
life safety, public utilities or other systems or facilities in the Building;
(2) in compliance with all applicable laws, codes, proffers, statutes and
regulations; (3) in such a manner as will not directly or indirectly interfere
with, delay, restrict or impose any expense, work or obligation upon Landlord in
the use or operation of the Building; (4) at Tenant's cost, including the cost
of repairing all damage to the Building and any personal injury and/or property
damage attributable to the installation, inspection, adjustment, maintenance,
removal or replacement of any equipment or apparatus on the roofs approved
hereunder; and (5) in a manner which will not void or invalidate any roof
warranty then in effect with respect to the roof of the Building. Tenant's Roof
Use shall be used solely in the ordinary course of Tenant's business operations
and specifically not for commercial resale or any similar purpose, and any use
of the roof outside of the ordinary course of Tenant's business operations (such
as, but not limited to, subleasing portions of the roof for profit to third
parties) shall be subject to Landlord's consent, which consent may be given or
withheld in Landlord's sole and absolute discretion.

         XDII. ACCESS.

Landlord shall install access control systems to the Common Area entrances of
the Building and Landlord shall provide on or before the Commencement Date, 100
key cards therefore, the cost of which shall be paid by Landlord. Thereafter,
Tenant may obtain from the applicable security system vendor as many key cards
as Tenant requires, at Tenant's sole expense (which shall be Landlord's actual
cost from the security company providing such service). All monitoring costs
attributable to such system(s), if any, shall constitute Operating Costs for all
purposes hereof.

         XDIII. AUTHORITY OF LANDLORD AND TENANT.

 Each of Landlord and Tenant shall furnish the other with appropriate
partnership and/or corporate resolutions, as applicable, confirming that the
individual executing this Lease on behalf of each has been duly authorized to
execute and deliver this Lease on behalf of such party and that this Lease is
binding upon such party.

         XDIV. NO ACCORD OR SATISFACTION.

No payment by Tenant or receipt by Landlord of a lesser amount than the Base
Rent, Additional Rent and other sums due hereunder shall be deemed to be other
than on account of the earliest Base Rent or other sums due, nor shall any
endorsement or statement on any check or accompanying any check or payment be
deemed an accord and satisfaction; and
<PAGE>   46
Landlord may accept such check or payment without prejudice to Landlord's right
to recover the balance of such Base Rent, Additional Rent or other sum and to
pursue any other remedy provided in this Lease.

         XDV. LEGAL REQUIREMENTS.

Landlord shall cause the Building (but not the Premises, for which Tenant shall
be solely responsible) to comply as of the Commencement Date with all laws,
orders, ordinances and regulations of Federal and local authorities and with
directions of public rules, recommendations, requirements and regulations of the
Board of Fire Underwriters, Landlord's insurance companies and any other
organization establishing insurance rates in the geographical area where the
Project is located and all applicable building codes, to the extent the same are
applicable to the Building, respecting all matters of the Project other than the
use and occupancy of the Premises by Tenant, including, without limitation, the
accessibility requirements of the Americans with Disabilities Act ("ADA"), all
zoning and other land use laws, and all Environmental Laws. To landlord's
knowledge, having done no independent investigation or inquiry, the proposed use
of the Premises by Tenant will not violate currently applicable zoning
regulations as they pertain to the Building.

         XDVI. PARKING.

Tenant shall have the right (together with Landlord and its agents, employees
and contractors, and together with the rights of other tenants in the Building
and the Project) to use, from the parking areas available to the Project in the
parking structure and surface parking on the Project and Common Areas an amount
of parking as set forth in Section 1.1 hereof (i.e., 49 aggregate spaces). Such
parking right shall be non-exclusive, and on an unreserved basis. Tenant agrees
not to overburden the Building's parking facilities.


         XDVII. GENERAL PROVISIONS.

         A. Acceptance. This Lease shall only become effective and binding upon
full execution hereof by Landlord and Tenant and delivery of a signed copy by
Landlord to Tenant.

         B. Joint Obligation. If there be more than one Tenant, the obligations
hereunder imposed shall be joint and several.

         C. Marginal Headings, Etc. The marginal headings, Table of Contents,

contained, subject to the provisions as to assignment, inure to and bind the

Landlord nor Tenant shall record this Lease or a memorandum hereof.

         G. Quiet Possession. Upon Tenant's paying the Base Rent and Additional
Rent reserved hereunder and observing and performing all of the covenants,
conditions and provisions on Tenant's part to be observed and performed

anyone claiming by, through or under Landlord, but in all events subject to all
the provisions of this Lease.

         H. Inability to Perform; Force Majeure. This Lease and the obligations
of the Tenant hereunder shall not be affected or impaired because either
Landlord or Tenant is unable to fulfill any of its obligations hereunder or is
delayed in doing so, to the extent such inability or delay is caused by reason
of war, civil unrest, strike, labor troubles, unusually inclement weather,
governmental delays, inability to procure services or materials despite
reasonable efforts, third party delays, acts of God, or any other cause(s)
beyond the reasonable control of the Landlord (which causes are referred to
collectively herein as "Force Majeure".) Any time specified obligation of
Landlord or Tenant in this Lease shall be extended one day for each day of delay
suffered by Landlord or Tenant as a result of the occurrence of any Force
Majeure. The foregoing notwithstanding in no event will an event of Force
Majeure extend the time within which Tenant or Landlord must perform any of its
monetary obligations under this Lease.

         I. Partial Invalidity. Any provision of this Lease which shall prove to
be invalid, void, or illegal shall in no way affect, impair or invalidate any
other provision hereof and such other provision(s) shall remain in full force
and effect.

         J. Cumulative Remedies. No remedy or election hereunder shall be deemed
exclusive but shall, whenever possible, be cumulative with all other remedies at
law or in equity.

         K. Entire Agreement. This Lease contains the entire agreement of the
parties hereto and no representations, inducements, promises or agreements, oral
or otherwise, between the parties, not embodied herein, shall be of any force or
effect.

         L. Survival. All indemnities set forth in this Lease shall survive the
expiration or earlier termination of this Lease.

         M. Consents. If any provision of this Lease subjects any action,
inaction, activity or other right or obligation of any party to the prior
consent or approval of the other, such consent shall not be unreasonably
withheld, conditioned or delayed unless otherwise specifically provided herein.
<PAGE>   48
         N. Saving Clause. In the event (but solely to the extent) the
limitations on Landlord's liability set forth in Section 8.3 of this Lease would
be held to be unenforceable or void in the absence of a modification holding the
Landlord liable to Tenant or to another person for injury, loss, damage or
liability arising from Landlord's omission, fault, negligence or other
misconduct on or about the Premises, or other areas of the Building appurtenant
thereto or used in connection therewith and not under Tenant's exclusive
control, then such provision shall be deemed modified as and to the extent (but
solely to the extent) necessary to render such provision enforceable under
applicable law. The foregoing shall not affect the application of Section 34 of
this Lease to limit the assets available for execution of any claim against
Landlord.

47.15 Rule Against Perpetuities. In order to ensure the compliance of this Lease
with any rule against perpetuities that may be in force in the state in which
the Premises are located, and without limiting or otherwise affecting either
Landlord's or Tenant's obligations under this Lease, as stated in the other
sections hereof, or modifying any other termination rights which may be set
forth herein, Landlord and Tenant agree that, irrespective of the reasons
therefor (other than a Default by Tenant), in the event Tenant fails to take
possession of the Premises and commence paying Base Rent and Additional Rent
hereunder within ten (10) years after the date of execution of this Lease, then
this Lease, and the obligations of the parties hereunder, shall be deemed to be
null and void and of no further force and effect. Without affecting the specific
timing requirements otherwise applicable thereto under this Lease, any and all
options granted to Tenant under this Lease (including, without limitation,
expansion, renewal, right of first refusal, right of first offer, and like
options) must be exercised by Tenant, if at all, during the term of this Lease.

         XDVIII. RULES AND REGULATIONS.

Tenant agrees to comply with the Rules and Regulations attached hereto as
Exhibit D.

         XDIX. ARBITRATION.

49.1 If arbitration is specifically agreed upon hereunder as a dispute
resolution procedure, the arbitration shall be conducted as provided in this
Section. All proceedings shall be conducted according to the Commercial
Arbitration Rules of the American Arbitration Association, except as hereinafter
provided. No action at law or in equity in connection with any such dispute
shall be brought until arbitration hereunder shall have been waived, either
expressly or pursuant to this Section. The judgment upon the award rendered in
any arbitration hereunder shall be final and binding on both parties hereto and
may be entered in any court having jurisdiction thereof. During any arbitration
proceeding pursuant to this Section, the parties shall continue to perform and
discharge all of their respective obligations under this Lease, except as
otherwise provided in this Lease.

49.2 All disputes that are required to be arbitrated in accordance with this
Lease shall be raised by notice to the other party, which notice shall state
with particularity the nature of the dispute and the demand for relief, making
specific reference by article number and title of the provisions of this Lease
alleged to have given rise to the dispute. The notice shall also refer to this
Section and shall state whether or not the party giving the notice demands
arbitration under this Section.
<PAGE>   49
49.3 Within thirty (30) days of any demand for arbitration, each of Tenant and
Landlord shall appoint one (1) arbitrator, and within ten (10) days of their
appointment, the two (2) arbitrators thus selected shall jointly select a third
(3rd) arbitrator. All arbitrators shall have at least ten (10) years' experience
in commercial real estate matters and, in particular, the subject matter of the
dispute, to act as arbitrator hereunder. If either party fails to select an
arbitrator within the initial thirty (30) day period, or if the two (2)
arbitrators are unable to agree upon a third (3rd) arbitrator, then, upon the
request of either party, the remaining arbitrator(s) shall be appointed by The
American Arbitration Association. The arbitration proceedings shall take place a
mutually acceptable location in the Washington, D.C./Baltimore metropolitan
areas.

49.4 The right of Landlord and Tenant to submit a dispute to arbitration is
limited to issues specifically agreed in this Lease to be submitted to
arbitration, and specifically does not apply to any remedial action undertaken
by Landlord pursuant to the provisions of Section 24 hereof. When resolving any
dispute, the arbitrator shall apply the pertinent provisions of this Lease
without departure therefrom in any respect. The arbitrator shall not have the
power to change any of the provisions of this Lease, but this Section shall not
prevent in any appropriate case the interpretation, construction and
determination by the arbitrator of the applicable provisions of this Lease to
the extent necessary in applying the same to the matters to be determined by
arbitration.

49.5 Without limitation, any dispute between Landlord and Tenant regarding the
application, interpretation or effect of the provisions of Exhibit C to
particular factual circumstances, including without limitation any dispute
regarding approval of plans and specifications for Tenant's Work, compliance of
construction with the approved plans and specifications therefor (or as
otherwise required by this Lease), Substantial Completion of all or any part of
Tenant's Work, completion of punch list items and Landlord's calculation of the
total Costs, shall be subject to arbitration pursuant to this Section 49 if
Landlord and Tenant cannot resolve such dispute voluntarily.

         D. WAIVER OF JURY TRIAL.

LANDLORD AND TENANT HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM BROUGHT BY EITHER OF THEM AGAINST THE OTHER ON ALL MATTERS ARISING
OUT OF THIS LEASE, OR THE USE AND OCCUPANCY OF THE PREMISES. IF LANDLORD
COMMENCES ANY SUMMARY PROCEEDING FOR NON-PAYMENT OF BASE RENT OR ADDITIONAL
RENT, TENANT WILL NOT INTERPOSE (AND WAIVES THE RIGHT TO INTERPOSE) ANY
NON-MANDATORY COUNTERCLAIM IN ANY SUCH PROCEEDING.

         DI. RENEWAL TERM.

         A. Provided Tenant is not in Default of this Lease at the time its
rights hereunder are to be exercised, Tenant shall have the option ("Renewal
Option") to extend the Lease Term for one (1) extension period of sixty (60)
months (the "Renewal Term") provided Tenant gives written notice to Landlord of
its election to exercise such Renewal Option (the "Renewal Notice") not more
than eighteen (18) nor less than twelve (12) months
<PAGE>   50
prior to the expiration of the last day of the initial Lease Term. Time is of
the essence in this Section 51.

         B. All terms and conditions of this Lease, including without
limitation, all provisions governing the payment of Additional Rent, shall
remain in full force and effect during the Renewal Term, except the Base Rent
shall be as set forth in this Section 51.

         C. The Base Rent payable upon the commencement of the Renewal Term
shall equal one hundred percent (100%) of the then prevailing market rental rate
(including base rental rate, annual escalation rate, and any applicable tenant
concessions) applicable to renewal terms with respect to comparable space in
comparable buildings in the Tysons Corner, Virginia area, (the "Fair Market
Rate" or "FMR") (but not less than the Rent for the prior Lease Year) at the
time of the commencement of the applicable Renewal Term, determined based upon
then existing renewal market conditions applicable to the leasing of comparable
space in comparable buildings in the vicinity of the Project (taking into
consideration use, location, quality, age and location of the applicable
building and the definition of net rentable area as well as then market lease
concessions, and improvement allowances). Further, the Fair Market Rate shall be
determined on a net basis, with Tenant remaining responsible for all Additional
Rent as set forth herein. Landlord and Tenant shall negotiate in good faith and
in accordance with the procedure set forth in Section 51.4, below, to determine
the Fair Market Rate which will be applicable during the Renewal Term, with the
goal of concluding such negotiation or triggering a determination of the FMR
using a three-broker method (as described in Section 51.5, below) within not
more than sixty (60) days after the date of Landlord's receipt of the Renewal
Notice.

         D. Within ten (10) days after Landlord receives Tenant's Renewal Notice
exercising the Renewal Option referenced above, Landlord will provide Tenant
with a written notice (the "FMR Notice") indicating the base rental rate and
annual escalation rate which Landlord in good faith believes represents the then
current FMR for the Premises. If Tenant is in agreement with the base rental
rate and annual escalation rate stated in the FMR Notice, Tenant shall so notify
Landlord within twenty (20) days after its receipt thereof, in which case such
base rental rate and annual escalation rate shall constitute the FMR for such
Renewal Term within the meaning of this Section 51. If Tenant believes in good
faith that the base rental rate and annual escalation rate stated by Landlord in
the FMR Notice are in excess of actual FMR for the Premises, Tenant shall so
notify Landlord in writing prior to the end of the twenty (20) day period after
Tenant received Landlord's FMR Notice, stating in its response (hereinafter
referred to as "Tenant's Counterproposal") the base rental rate and annual
escalation rate which Tenant in good faith believes represents the then current
FMR for the Premises. If Tenant fails to respond to the Landlord's FMR Notice
within such twenty (20) day period, Tenant shall be deemed to have accepted the
base rental rate and annual escalation rate stated in Landlord's FMR Notice. If
Tenant does provide Tenant's Counterproposal to Landlord in a timely fashion,
and Landlord agrees that the base rental rate and annual escalation rate stated
in Tenant's Counterproposal represent the then current FMR, Landlord shall so
notify Tenant within twenty (20) days after its receipt thereof, in which case
such base rental rate and annual escalation rate shall constitute the FMR for
such Renewal Term within the meaning of this Section 51. If Landlord fails to
respond to the Tenant's Counterproposal within twenty (20) days after Landlord's
receipt of the Tenant's Counterproposal, or rejects the rental rate and
escalation rate stated therein, then the parties
<PAGE>   51
agree to submit the issue of what constitutes the appropriate FMR for the
Premises for the Renewal Term to determination using a "three broker method" as
described in Section 51.5, below.

         E. If the parties submit the issue of what constitutes the appropriate
FMR for the Premises for the Renewal Term to determination using a "three broker
method", then the Base Rent and annual escalations applicable during the Renewal
Term shall be equal to the FMR and annual escalation rates determined by a board
of three (3) licensed real estate brokers, one of whom shall be named by
Landlord, one by Tenant, and the two so appointed shall select the third. Each
member of the board of brokers shall be licensed in the Commonwealth of Virginia
as a real estate broker, with a substantial familiarity in the field of
commercial office leasing in McLean, Virginia having no less than ten (10) years
experience in such field, and recognized as ethical and reputable within the
field. Landlord and Tenant agree to make their appointments within five (5)
business days after the earlier to occur of (i) the expiration of the ten (10)
day period after Landlord's receipt of Tenant's Counterproposal, or (ii) the
date Landlord notifies Tenant of its rejection of Tenant's Counterproposal. The
two (2) brokers selected by Landlord and Tenant shall promptly select a third
broker within ten (10) days after they both have been appointed, and each
broker, within ten (10) days after the third broker is selected, shall submit
his or her determination of the said FMR and escalations (taking into account
the provisions of Section 51.3 hereof). If either of the parties fail to select
a broker within the aforesaid time periods, the broker selected by the other
party shall select the other two (2) brokers to participate in the
determination, each of which shall meet the selection criteria set forth above,
and be affiliated with a different company from the first broker and from each
other; and if the brokers selected by Landlord and Tenant are unable to reach
agreement on the identity of the third broker within the applicable ten (10) day
period, then the third broker shall be designated (in compliance with the
applicable criteria set forth above) by an agent of the Virginia Board of
Realtors in office at such time. The FMR shall be the average of amount
determined by the two brokers whose determinations are closest in amount to each
other (or [a] if two brokers reach an identical determination, the determination
of such two brokers, or, as applicable [b] if two brokers' estimates are the
same monetary difference from the third, but in opposite directions, the average
of the three brokers shall prevail), provided that if the two (2) most proximate
determinations of FMR differ by more than five percent (5%), then the
determination of FMR by such board of three brokers shall be null and void, and
Landlord and Tenant shall, within five (5) business days thereafter, appoint a
new board of three different real estate brokers meeting the above-stated
criteria, who shall convene in accordance with the procedures and time frames
set forth above in order to render a new determination, as if the first
determination had never taken place. After the Fair Market Rent has been
established, the brokers shall immediately notify the parties in writing, and
such determination shall be conclusive and binding upon the parties. Landlord
and Tenant shall each pay the fee of the broker selected by it, and they shall
equally share the payment of the fee of the third broker.

IN WITNESS WHEREOF, Landlord and Tenant have executed this Deed of Lease, or
have caused this Deed of Lease to be executed on their respective behalves by
their duly authorized officers, as of the day and year first above written.

                                       LANDLORD:

                               Description of Land
<PAGE>   55
                                    EXHIBIT C

                        Construction/Build-Out Provisions
                        Landlord's Work and Tenant's Work

         1. Preparation of Plans and Specifications. Landlord and Tenant on a
preliminary space plan for the construction of initial leasehold improvements to
the Premises (the "Space Plan"), a copy of which is attached as Schedule C-1
hereto and made a part hereof. (The Space Plan includes related specifications
for interior tenant finishes, to the extent same deviate from Building
standard.) With respect to such initial leasehold improvements, within ten (10)
days after the execution of this Lease, Tenant shall submit to Landlord all
information (the "Plans Information") needed in order for Landlord's architects,
engineers and/or other construction personnel ("Landlord's Architect") to
prepare architectural plans, construction drawings and finishes for the
Premises, consistent with the Space Plan. Landlord shall provide all Building
systems information necessary for Landlord's Architect to prepare mechanical,
electrical and plumbing ("MEP") drawings. Within thirty (30) days of receipt of
all information required from Tenant, Landlord's Architect shall prepare the
architectural plans, construction drawings and finishes, and the MEP's, for the
Premises, as required for the permitting and construction of the Premises
("Plans and Specifications"). Landlord shall deliver the completed Plans and
Specifications to Tenant promptly after completion. If Tenant fails to provide
all necessary Plans Information, Landlord or Landlord's Architect shall notify
Tenant of any such missing information, and Tenant shall deliver same to
Landlord within five (5) days after such notification. Any period of delay
caused by Tenant's failure to provide all the Plans Information when required
above shall toll the aforementioned thirty (30) day period until Tenant delivers
such information, and shall constitute a "Tenant Delay" (as defined in paragraph
9 of this Exhibit C, below) hereunder.

         2. Approval of Plans and Specifications. As soon as practicable after
receipt of such Plans and Specifications, but in no event more than five (5)
days after receipt thereof, Tenant shall return to Landlord such Plans and
Specifications with Tenant's suggested modifications and/or approval. If, upon
receipt of Tenant's modified Plans and Specifications, Landlord wishes to take
exception to Tenant's modifications, Landlord may do so within five (5) business
days after the date upon which Landlord receives Tenant's modified Plans and
Specifications. If Landlord takes exception, then Landlord and Tenant shall
negotiate in good faith to promptly resolve any disagreements and make
modifications to the Plans and Specifications which are acceptable to Landlord
and Tenant. The parties shall attempt to reach agreement as soon as possible,
and in all events within five (5) business days after the date upon which
Landlord receives Tenant's proposed modifications to the Plans and
Specifications.

         3. Revisions to Plans and Specifications. If Tenant's modifications are
acceptable to Landlord, said Plans and Specifications shall thereafter be
revised by Landlord to reflect the applicable changes, and the same shall be
resubmitted to Tenant for approval within five (5) business days after their
receipt by Landlord. If Landlord takes exception to Tenant's modifications, said
Plans and Specifications shall be revised by Landlord to reflect any changes
agreed upon in the above referenced good faith negotiations within three (3)
business days after the expiration of the five (5) business day negotiating
period set forth in paragraph 2, above. Landlord shall deliver the revised Plans
and Specifications to Tenant prior to the expiration of such three (3) business
day period, and Tenant shall grant its approval or disapproval thereto, and/or
state any further objections or proposed modifications, within three (3)
business days after receipt thereof. After the first submission and
resubmission, Landlord and Tenant agree to restrict further objections or
disputes to matters which have not previously been agreed upon or accepted by
the other party. The parties shall, in all events, act in good faith and use all
reasonable efforts to reach agreement as soon as possible, and in all events
within fifteen (15) 
<PAGE>   56
business days after the date upon which Landlord first received Tenant's
modified Plans and Specifications. The process of submissions and resubmissions
shall continue thereafter until final agreement is reached, and in such process,
the parties shall thereafter adhere to the three (3) business day response time
required after the second resubmission. Each party agrees that its failure to
respond to a submission or resubmission within the above-referenced time frames
shall constitute such party's acceptance of the submission or resubmission in
question.

         4.       Landlord's Work.

                  (A) Upon Landlord and Tenant's final approval of the Plans and
Specifications, the same shall constitute the "Approved Plans", and the work
shown on the Approved Plans shall be deemed "Landlord's Work" unless otherwise
noted thereon. Following final approval of the Approved Plans, Landlord agrees
to apply for a building permit and upon the later of the date of issuance
thereof, or that date which is fifteen (15) days after the existing tenant
occupying the Premises vacates therefrom, to cause Landlord's Work to be
completed, installed or performed, as the case may be, in accordance therewith,
subject only to minor variations and/or variations necessitated by the
unavailability of specified materials and equipment. The costs associated with
Landlord's Work shall be paid as provided in Paragraphs 6 and 7, below.

                  (B) Except as above provided, no deviation from the Approved
Plans shall be made by either party except by written change order approved by
the other party, which approval shall not be unreasonably withheld or delayed.
In the event Tenant requests or causes the need for any change orders with
respect to Landlord's Work, the net cost of such change orders shall be at
Tenant's sole cost and any delays resulting therefrom shall constitute "Tenant
Delays" hereunder. In the event any change orders increase the cost of
Landlord's Work, Tenant shall pay Landlord the incremental additional cost
associated with any such change orders within fifteen (15) days after Landlord's
demand therefor.

         5.       Tenant's Work.

                  (A) Notwithstanding anything to the contrary in this Exhibit
C, Tenant shall be responsible for all work, construction, installations or
improvements in or to the Premises which are not designated as Landlord's Work
(including but not limited to all fixtures, furniture, equipment and other
office installations.) Such work shall hereinafter be referred to as "Tenant's
Work," and shall be at Tenant's sole cost and expense. Prior to commencing
Tenant's Work, Tenant shall submit to Landlord, for Landlord's review and
approval, which shall not be unreasonably withheld, drawings and specifications
for Tenant's Work, showing all aspects of such work. Tenant's Work shall be
deemed to constitute an "alteration" within the meaning of Section 15 of the
Lease, and shall be subject to the terms of (and approval procedures described
in) Section 15 of the Lease even if Tenant's Work takes place prior to the
Commencement Date of this Lease.

                  (B) Tenant shall be responsible for and shall pay when due all
costs associated with the preparation of plans and the performance of Tenant's
Work incurred in accordance with this Exhibit C. Failure by Tenant to pay the
costs associated with Tenant's Work on a timely basis so as to avoid the
assertion of any statutory and/or common law lien against the Premises or the
Building shall constitute a default by Tenant for all purposes of the Lease.

         6. Improvement Allowance Defined. In consideration of Tenant's
fulfillment of all of its obligations under this Exhibit C and the performance
of all of its financial and other obligations under the Lease, Landlord shall
make a one-time contribution of up to $131,710.00 (which is calculated as
<PAGE>   57
$10.00 per rentable square foot of the Premises), to be applied solely toward
actual hard and soft costs paid by Landlord in the design, purchase,
construction and installation of Landlord's Work and for no other purpose, in
accordance with the terms of this Exhibit C. Landlord's total financial
obligation with respect to the purchase, construction, and installation of
Landlord's Work or any other improvements to the Premises shall be limited
solely to the Improvement Allowance, and Tenant shall be solely responsible for
any and all such costs in excess of the Improvement Allowance. Costs to be
applied against the Improvement Allowance shall include, without limitation,
architectural and engineering fees and expenses associated with the preparation
and review of the Plans and Specifications and the Approved Plans (both prior to
and after the date of the Lease); permit and inspection fees; cost of labor,
materials, general conditions and contractor profits arising under the
construction contract(s) pursuant to which Landlord's Work is performed; a
construction management fee payable to Landlord's construction manager in the
amount of four percent of managed costs; and any other hard and soft costs
associated with the performance of the Landlord's Work.

         7.       Improvement Allowance Payment Schedule.

                  (A) Landlord shall apply the Improvement Allowance toward the
cost of Landlord's Work, as defined by and in accordance with the terms of this
Exhibit C. Landlord agrees that the Improvement Allowance shall be applied
solely to pay costs of design and construction of Landlord's Work in the
Premises.

                  (B) If, during the course of performing Landlord's Work,
Landlord in good faith believes that the cost of Landlord's Work will exceed the
Improvement Allowance, Landlord shall notify Tenant in writing, which notice
shall include Landlord's good faith estimate of the additional cost to complete
Landlord's Work (the "Completion Deposit"). Within fifteen (15) days after
receipt of such notice, Tenant shall pay Landlord (or, if Landlord elects,
Tenant shall pay Landlord's contractor) the Completion Deposit. If Tenant fails
to pay the Completion Deposit as and when due hereunder, (i) such failure shall
constitute a Tenant Delay and a default under the Lease, and (ii) Landlord shall
have the right to halt Landlord's Work.

                  (C) The following provisions shall apply with respect to any
underpayment or overpayment by Tenant in the event Tenant pays the Completion
Deposit hereunder. If the Final Statement states that the Actual Cost exceeds
the sum of the Improvement Allowance and (if any) the Completion Deposit (the
"Total Tenant Payment"), then Tenant shall pay Landlord an amount equal to the
difference between the Actual Cost and the Total Tenant Payment within fifteen
(15) days after receipt of Landlord's statement. If the Final Statement states
that the Actual Cost is less than the Total Tenant Payment, then Landlord shall
credit the unused portion of the Total Tenant Payment (but not more than the
unused portion of the Completion Deposit) toward Tenant's next due payment(s) of
Rent and additional rent.

         8.       Permits.

                  (A) Except as provided below, Landlord shall obtain all
necessary permits in connection with Landlord's Work. Landlord's Work shall not
be deemed Substantially Complete until Landlord obtains all final inspection
approvals which are required for Landlord to deliver the Premises to Tenant with
Landlord's Work completed, and that can be obtained by Landlord prior to Tenant
performing Tenant's Work and prior to Tenant installing its fixtures, furniture
and equipment (including, if the same may be issued prior to Tenant's
performance of Tenant's Work, if any, and installation of its fixtures,
furniture and equipment , a non residential use permit for the Premises).
<PAGE>   58
                  (B) Tenant shall be responsible for applying for and obtaining
all permits required for Tenant to perform Tenant's Work, or to operate within
the Premises, including without limitation (and except as provided in Paragraph
8(A), above) the final non residential use permit or its equivalent, and for
obtaining any final fire inspection approval required after installation of its
fixtures, furniture and equipment.

         9. Tenant Delays. Tenant acknowledges that delays in preparation of
Approved Plans and/or in the construction of Landlord's Work caused by Tenant
may otherwise result in deferral of the Possession Date (defined below), and
consequently the Commencement Date (as such term is defined in Section 1.4 of
the Lease), and thus Tenant's obligation to pay Rent, additional rent and other
charges due under this Lease to Landlord. Accordingly, Tenant agrees that the
Commencement Date shall be deemed to have been moved up one (1) day for each day
of delay in the commencement or completion of Landlord's Work occasioned by any
"Tenant Delay", which term shall include, without limitation, any delay in the
commencement or completion of Landlord's Work caused by the acts or omissions of
Tenant, its agents, architects, employees, contractors and invitees. (For
purposes of illustration only, if the Commencement Date is April 15, 1999, and
there were ten (10) days of Tenant Delays, the Commencement Date shall be deemed
to have occurred on April 5, 1999.)

         10. Delivery & Acceptance of Possession. When Landlord's Work is
substantially complete, Landlord shall deliver to Tenant a written notice (the
"Completion Notice") certifying that Landlord's Work is "Substantially Complete"
(as defined in the Lease). Within five (5) days after Landlord delivers the
Completion Notice, Tenant and a representative of Landlord shall jointly inspect
the Premises, as Tenant deems appropriate and Tenant shall be deemed to have
accepted the Premises (in their condition as of the date of the Completion
Notice but without waiving Landlord's ability, if any, to correct punch list
items pursuant to Paragraph 11 below) on the earlier of (i) the date of such
joint inspection, or (ii) the fifth (5th) day after Landlord delivers the
Completion Notice; which date may be referred to hereinafter as the "Possession
Date."

         11. Punch List. If, as a result of the aforementioned joint inspection,
Tenant discovers minor deviations or variations from the Approved Plans of a
nature commonly found on a "punch list" (as that term is used in the
construction industry), Tenant shall promptly notify Landlord of such
deviations; provided, however, that in the event of a dispute, Landlord (or
Landlord's Architect) and Tenant (or Tenant's architect) shall negotiate in good
faith, using their reasonable discretion, to determine which items constitute
punch list items. The existence of such punch list items shall not postpone the
Commencement Date of this Lease nor the obligation of Tenant to pay Rent,
additional rent or any other charges due under this Lease.

         12. Provisions Regarding Tenant's Work. The following shall apply with
respect to Tenant's Work, and any subsequent alterations to the Premises
(hereafter, "alterations") by Tenant made pursuant to section 15 of the Lease.

                  (A) First-Class Lien-Free Completion. Tenant shall only use
new, first-class materials in connection with Tenant's Work and alterations, and
same shall be paid for in full and in a timely fashion by Tenant, and shall be
performed in a lien-free, first-class, and good and workmanlike manner, and in
accordance with applicable codes and requirements. Tenant's Work and alterations
shall comply with the requirements of the Americans with Disabilities Act
("ADA").
                  (B) Bonding. All contractors and subcontractors performing any
work on behalf of Tenant within the Premises shall be subject to Landlord's
approval, and shall be bonded (or, at Landlord's
<PAGE>   59
option, bondable) and licensed to do business in jurisdiction within which the
Premises is located.

                  (C) Insurance Requirements During Construction.

                           (1) Tenant shall secure, pay for, and maintain, or
cause its contractors and subcontractors to secure, pay for, and maintain,
during the continuance of construction and fixturing work within the Premises,
all of the insurance policies required in the amounts as set forth herein,
together with such insurance as may from time to time be required by city,
county, state or federal laws, codes, regulations or authorities.

                           (2) Tenant's Work and alterations may not commence,
nor may either party permit its contractors and subcontractors to commence any
work, until all required insurance has been obtained, and, if Landlord requests,
until Tenant's certificates of such insurance have been delivered to Landlord.
Tenant's insurance policies shall name the Landlord, Landlord's mortgagee(s) and
Landlord's Architect and general contractor for the Premises as additional
insureds. Tenant's certificates of insurance shall provide that no change or
cancellation of such insurance coverage shall be undertaken without thirty (30)
days' prior written notice to Landlord.

                           (3) Landlord shall have the right to require Tenant,
and Tenant shall have the duty, to stop work in the Premises immediately if any
of the coverage Tenant is required to carry herein lapses during the course of
the work, in which event Tenant's Work (or alterations) may not be resumed until
the required insurance is obtained and satisfactory evidence of same is provided
to Landlord.

                           (4) In the event Tenant employs a contractor or
subcontractor to perform all or part of Tenant's Work and/or alterations, Tenant
shall purchase, or cause its contractor to carry, General Contractor's and
Subcontractor's Required Minimum Coverages and Limits of Liability as follows
(the insurance required under this Exhibit C shall be in addition to any and all
insurance required to be procured by Tenant pursuant to the terms of the Lease):

                           required by any Employee Benefit Act or similar
                           statute applicable where the work is to be performed,
                           as will protect the contractor and subcontractors
                           from any and all liability under the aforementioned
                           act(s) or similar statute.

                                    (ii) Comprehensive General Liability
                           Insurance (including Contractor's Protective
                           Liability) in an amount not less than $5,000,000 per

                           damage liability or a combination thereof (combined
                           single limit coverage) with a minimum aggregate limit
                           of $5,000,000. Such insurance shall insure Tenant's
                           general contractor against any and all claims for
                           personal injury, death, and damage to the property of
                           others arising from its operations under its
                           contract, whether such operations are performed by
                           Tenant's contractors, subcontractors, or
                           sub-subcontractors, or by anyone directly or
                           indirectly employed by any of them.

                           operation of any automotive equipment, whether
<PAGE>   60
                           owned, leased, or otherwise held, including
                           employer's non-ownership and hired car liability
                           endorsements, in an amount not less than $2,000,000
                           per occurrence and $2,000,000 aggregate, combined
                           single limit bodily injury and property damage
                           liability.

         (D) Tenant agrees that Landlord will have the right to inspect the
performance of Tenant's Work or alterations by Tenant's contractor(s) and
subcontractor(s), through Landlord's construction manager, and Tenant agrees to
cooperate with Landlord to facilitate such inspection, including without
limitation: (a) notifying Landlord and such construction manager prior to any
and all government inspections of Tenant's Work so that Landlord's construction
manager can be present therefor; (b) permitting Landlord's construction manager
free and clear access to the Premises during the construction period, as
necessary to perform such inspections, and (c) complying (or causing its
contractor to comply) with the reasonable directions of such construction
manager in connection with Tenant's Work or alterations, as long as such
directions are not inconsistent with the Approved Plans. Landlord shall use
reasonable efforts not to interfere unreasonably with the performance of
Tenant's Work during the course of any inspections by Landlord or Landlord's
construction manager pursuant to this Paragraph 12(D)

         (E) In the performance of Tenant's Work or alterations in accordance
with this Lease, Tenant shall cause its contractor to use reasonable and
diligent efforts not to interfere with ongoing operations in the Building.
Without limiting the foregoing, Tenant agrees to cause its contractor to use
reasonable and diligent efforts to minimize excess noise, and to limit its
construction activities to the portion of the Premises being constructed and
those portions of the common area (if any) in which Tenant is permitted to
perform alterations or Tenant's Work in accordance with the Approved Plans.

         (F) Tenant's contractor shall be responsible for all utility costs
associated with the performance of Tenant's Work or alterations and shall either
supply its own electricity and other utilities, or shall reimburse Landlord for
all utility consumption associated with such work. Tenant's contractor shall
keep all construction areas reasonably clean and free of trash and debris, and
shall police the activities of its contractors, subcontractors and their
respective employees with regard to keeping the Building and land clean, and not
disturbing the other tenants and occupants of the Building in the course of such
construction activities. Tenant agrees to follow (or to cause its contractors
and subcontractors to follow) all reasonable directions given to Tenant or its
contractor and subcontractors by Landlord's construction manager. Tenant's
construction contract shall indemnify Tenant and Landlord from damages, losses
and expenses associated with the acts and omissions of Tenant's contractor, its
agents, employees and subcontractors, and shall otherwise be subject to
Landlord's prior reasonable approval.

         (G) Tenant shall provide to Landlord copies of all applications for
permits, copies of all governmental inspection reports and/or certificates, and
any and all notices or violations communicated to Tenant or its contractors by
applicable governmental authorities, promptly upon receipt and/or submission
thereof, as the case may be. Tenant agrees to comply (or to cause its
contractors to comply) with all applicable federal, state and local laws,
regulations and ordinances in the performance of Tenant's Work or alterations,
and to promptly rectify any violations of such laws caused by the acts or
omission of Tenant, its employees, agents and/or contractors, and Tenant shall
be responsible for any non-compliance by Tenant or its agents, employees and
contractors. In the event (i) of any violation of this Exhibit C, or (ii) the
construction of any improvements in the Premises which are not within the scope
of the Approved Plans (or other Landlord-approved plans), Landlord shall have
the right to cause Tenant and Tenant's contractor to stop Tenant's Work or
alterations and to remove any such improvements which have been constructed in
violation of the Approved Plans (or other Landlord-approved plans) or this
Exhibit C at Tenant's expense, and to seek any and all appropriate legal and
<PAGE>   61
equitable relief in order to enforce the provisions of this Exhibit C.

Landlord's agent will be prevented by the on-site security guard.

         20. Tenant shall store all its trash and garbage within the Premises.

Dear Sirs:

         This estoppel certificate is given to you such that you, your lenders

company ("Landlord/Assignor"). A copy of the Deed of Lease and any amendments,
exhibits and addenda thereto is attached hereto as Exhibit A (the "Lease").
Tenant hereby represents to Landlord and to ____________________________

         (a)      Tenant has accepted and is occupying the Premises;

         (b)      the Lease has not been modified or amended except as stated in
                  the documents attached hereto as Exhibit A, and constitutes

         WHEREAS, Sublessor, as "Tenant", entered into a lease with Metropolitan
Life Insurance Company and Centennial Equities Corporation, as joint venturers
doing business as "Perimeter Center Properties" (the "Prime Landlord"), as
"Landlord", originally dated September 8, 1983, as amended from time to time
(collectively the "Prime Lease"), pursuant to which Sublessor leased all of that
certain building known as "Building 64A" at Perimeter Center (the "Building").
Said Prime Lease to which reference is made above is incorporated herein by this
reference. The Building and the land upon which said Building is located (which

described on Exhibit "A", attached hereto and by this reference incorporated
herein, is herein referred to as the "Property".

         WHEREAS, Sublessor and Sublessee have agreed that Sublessor shall
sublet approximately 7,240 rentable square feet of such space as rented under
the Prime Lease to Sublessee, as such space is shown on Exhibit "B", upon the
terms and conditions as herein described.

         NOW THEREFORE, for Ten and No/100 Dollars ($10.00) and other good and
valuable consideration, paid by the parties hereto to one another, the receipt
and sufficiency of which are hereby acknowledged by the parties hereto, the
parties hereto hereby covenant and agree as follows:

1.       Premises and Rent

         (a) Sublessor hereby subleases and rents to Sublessee, and Sublessee
hereby subleases and rents from Sublessor, under the sublease arrangement set
forth herein, 7,240 rentable square feet of space ( the "Sublease Premises") as
shown on Exhibit "B", being a portion of the rentable space on floor G1. Such
space is immediately available for Sublessee to perform tenant fit-up and finish
work therein, subject to the terms of Paragraph 2 herein. "Base Rent" (as
described herein) will commence upon the occupancy of the Sublease Premises by
Sublessee for the purpose of conducting business, but no later than July 1, 1998

         (b) The Base Rent for the Sublease Premises due from Sublessee to
Sublessor shall be at an annual rate of $25.59 per rentable square foot per
annum, exclusive of the cost of electricity, which will be metered and paid

will escalate by three percent (3%) per annum, on each anniversary date of the
Commencement Date. Exhibit "C", by this reference incorporated herein, is a

                             Atlanta, Georgia 30303

                             Attention: Joyce Baker

         (d) The Sublease Premises shall include Sublessee's right to use, in
common with others, public lobbies, entrances, stairs, corridors, elevators,
cafeterias (if any), and other public portions of the Building. All the windows
and outside walls of the Sublease Premises, and any space in the Sublease
Premises used for shafts, pipes, conduits, ducts, telephone ducts and equipment,
electric or other utilities, sinks or other Building facilities, and the use
thereof and access thereto through the Sublease Premises for the purposes of
operation, maintenance, inspection, display and repairs are hereby reserved to
Sublessor. No easement for light, air or view is granted or implied hereunder,
and the reduction or elimination of Sublessee's light, air or view will not
affect this Sublease.

         (e) Sublessee shall install, at Sublessee's sole cost, meters to
separately meter the electricity distributed to and consumed in the Sublease
Premises.

2. Term. The term of the Sublease shall begin upon the Commencement Date,
and end on June 30, 2003. However, Sublessee shall have the right to access to
the Sublease Premises upon the due execution of this Sublease by all parties
hereto, to perform work therein under the terms of this Sublease, but without
the obligation to pay Base Rent until the Commencement Date.

3. No Assignment.

         (a) Except as set forth below Sublessee shall not assign this Sublease
nor sublet the Sublease in whole or in part and shall not permit Sublessee's
interest in this Sublease to be vested in any third party by operation of law or
otherwise, without obtaining Sublessor's prior written consent, such consent not
to be unreasonably withheld, conditioned or delayed. Sublessor shall give notice
to Sublessee with Sublessor's response to any proposed assignment or sublease
within twenty (20) days after Sublessor receives all of the "Required Sublease
Information" (as that term is herein defined).

         (b) Sublessee shall, however, have the right to assign the Sublease or
sub-sublet the Sublease Premises, or any part thereof, without Sublessor's
consent, and without submitting to Sublessor the Required Sublease Information,
but subject to Sublessor's rights to notice and prohibition contained in this
subparagraph (b), to (i) any entity which controls, is controlled by, or is
under common control with, Sublessee, (ii) any entity resulting from a merger or
consolidation with Sublessee, (iii) any entity which acquires all or
substantially all the assets of Sublessee or of an entity described in this
subparagraph (b) (iv) any entity which acquires all or substantially all of the
assets of a division, affiliate or subsidiary of Sublessee or a division of an
entity described in this subparagraph (b), but only if such organization is
occupying the Sublease Premises, or (v) any entity which acquires a line of
business from Sublessee, and such line of business was conducted in the Sublease
Premises. Sublessee shall have the obligation to notify Sublessor of its intent
to enter into any such arrangement, and if Sublessor reasonably determines that
the proposed assignee


                                      -2-
<PAGE>   3

would cause a violation by Sublessor of its obligations under the Prime Lease,
Sublessor shall have the right to prohibit such arrangement based upon the issue
of violation by Sublessor of its obligations under the Prime Lease, by giving
written notice thereof, acknowledged by Prime Landlord, within ten (10) days of
receipt of Sublessee's notice.

         (c) No assignment or subletting shall affect the continuing primary
liability of Sublessee (which, following assignment, shall be joint and several
with the assignee), and Sublessee shall not be released from performing any of
the terms, covenants and conditions of this Lease, unless Sublessor, after
giving due consideration to the issue, believes in its sole and absolute
discretion that the credit history, net assets, cash on hand and other relevant
financial strengths of the assignee or sublessee are such that its interests are
sufficiently protected after releasing Sublessee from liability.

         (d) For the purposes of this Paragraph the Required Sublease
Information shall include the following: (i)the identity and business of the
proposed sublessee or assignee; (ii) financial information from the previous
three (3) years and a credit history of the proposed sublessee or assignee;
(iii) a copy of the proposed sublease or assignment of lease to which Sublessee
intends to be a party; (iv) the proposed use of the space by the proposed
sublessee or assignee.

         (e) Notwithstanding any provision in this Sublease to the contrary, it
shall not be unreasonable for Sublessor to withhold its consent to any proposed
transfer, assignment, or subletting of the Sublease Premises if (i) the proposed
transferee's anticipated use of the Sublease Premises involves the generation,
storage, use, treatment, or disposal of Hazardous Material, other than any
"Permitted Hazardous Material" (as that term is herein defined); or (ii) the
proposed transferee has been required by any prior landlord, lender, or
governmental authority to take remedial action in connection with Hazardous
Material contaminating a property if the contamination resulted from such
transferee's actions or use of the property in question.

         (f) Except in the case of Sublessee's assignment or sub-sublease under
subparagraph (b) above, Sublessee shall reimburse Sublessor on demand for any
reasonable costs that Sublessor may incur in connection with said assignment or
sublease, including the reasonable costs actually paid, if any, of investigating
the acceptability of the proposed assignee or subtenant, and reasonable legal
costs incurred in connection with the granting or withholding of any requested
consent, up to, but not in excess of, Five Hundred and No/100 Dollars ($500.00)
per request.

4. Tenant Improvement Allowance. Sublessor shall provide to Sublessee a tenant
improvement allowance of up to $21,720, which is equal to $3.00 per rentable
square foot of the Sublease Premises. Such amount will be payable by Sublessor
to Sublessee in one lump sum cash payment within 30 days of the due execution of
this Sublease by all parties thereto.

5. Renewal Right. For so long as no Event of Default has occurred and is
continuing, and Sublessee (and not a sub-sublessee or an assignee of Sublessee)
is in occupancy of the Sublease Premises, Sublessee shall have the one time
right to renew this Lease for the period from July 1, 2003, through February 28,
2006, at the then escalated Base Rent rate, with such Base Rent rate continuing
to escalate at a rate of three percent (3%) per annum, on each anniversary of
the Commencement Date. Such right must be exercised no later than October 31,
2002 by a notice to Sublessor.

6. Omitted.

7. Letter of Credit. (a) Sublessee shall deliver to Sublessor an irrevocable,
unconditional letter of credit in favor of Sublessor in an initial amount (as
may be reduced as set forth below) of $99,999.00, in a form acceptable to
Sublessor and issued by a bank, acceptable to Sublessor, in or having a
correspondent bank in the Atlanta, Georgia metropolitan area. If Sublessee
defaults or otherwise fails to comply with the terms of the Sublease for any
reason, Sublessor may immediately draw upon and receive payment under said
letter of credit, it being the express intent of Sublessor and Sublessee that
the letter of credit be used as a security deposit, securing the full and
complete performance by Sublessee of Sublessee obligations under the Sublease.
Any such draw by Sublessor shall include a statement that an Event of Default on
the part of Sublessee has occurred and is continuing. Such letter of credit
shall permit transfers of the payee thereunder if Sublessor transfers its
interest in the Sublease Premises or the Building. The letter of credit shall be
open and may be drawn upon for a period which expires one (1) month after the
scheduled expiration of the Term; provided however, that such letter of credit
may be a duration shorter than said period so long as Sublessee replaces said
letter of credit with a new letter of credit, on the same terms and conditions,
and in the same amount, as the prior letter of credit, at least one (1) month
prior to the expiration of the prior letter of credit. If Sublessee fails to
replace a prior letter of credit within the period required herein, then
Sublessor shall be immediately authorized and entitled to demand and receive
payment under said letter of credit, and to apply and hold the proceeds
therefrom as a security deposit. If such a security deposit is created as a
result of this paragraph and there is an Event of Default on the part of
Sublessee under the Sublease for any reason, Sublessor may, after giving five
(5) days advance notice to Sublessee, without prejudice to Sublessor's other
remedies, apply part or all of the Security Deposit to cure Sublessee's default.
If Sublessor so uses part or all of the Security Deposit, then Sublessee shall
with ten (10) days after written demand, pay Sublessor the amount used to
restore the Security Deposit to its original amount.

         (b) If no Event of Default on the part of Sublessee has occurred and is
continuing, and Sublessor has not previously drawn upon the letter of credit,
then on or after the 1st anniversary of the Commencement Date, the amount of
letter of credit may be reduced (by a replacement letter of credit, in
accordance with the terms of Paragraph 7(a) above), by Tenant to a letter of
credit in the face amount of $84,560.00.

         (c) If no Event of Default on the part of Sublessee has occurred and is
continuing, and Sublessor has not previously drawn upon the letter of credit,
then on or after the 2nd anniversary of the Commencement Date, the amount of
letter of credit may be reduced (by a replacement letter of credit, in
accordance with the terms of Paragraph 7(a) above), by Tenant to a letter of
credit in the face amount of $70,121.00.

8. Other Charges; Operating Costs. Normal operating costs for a data center
operation are included in the Base Rent. These include 24 hours per day, 7 days
per week, HVAC support, secured access, raised computer flooring, and special
fire protection systems. Also included in the Base Rent will be Uninterruptable
Power Service ("UPS"), through the Building's UPS system. In addition to the
Base Rent, Sublessee will reimburse Sublessor for any special operating costs as
reasonably determined by Sublessor, if such costs are incurred due to or as a
result of additional services requested by Sublessee.

9. Subordinate to Prime Lease. This Sublease is subject and subordinate in all
instances and under all circumstances to the Prime Lease. Except as may be
inconsistent with the terms hereof,


                                      -4-
<PAGE>   5

all the terms, covenants and conditions in the Prime Lease contained shall be
applicable to this Sublease with the same force and affect as if Sublessor were
the "Landlord" under the Prime Lease and Sublessee were the "Tenant" thereunder;
and in case of any breach hereof by Sublessee, Sublessor shall have all the
rights against Sublessee as would be available to Prime Landlord against
Sublessor as "Tenant" under the Prime Lease.

10. Omitted

11. Omitted.

12. Use. Sublessee shall use the Sublease Premises in accordance with and
subject to the Prime Lease, and in a manner which does not interfere with
Sublessor or create any disturbance or nuisance to any other party, including
any other subtenants or users of the Building. The Sublease Premises may be used
as a data center, plus general office purposes incidental thereto and, in
connection therewith, Sublessee may permit servers or other such equipment of
third-parties to be placed or located within the Sublease Premises, and such use
by third-parties shall not be deemed a sublease or assignment for the purposes
of this Sublease. The use by Sublessee as contemplated above does not, to
Sublessor's knowledge, violate the terms of any certificate of occupancy issued
for the Sublease Premises.

13. Condition of Sublease Premises; Review by Sublease.

         (a) Sublessee shall take the Sublease Premises "as is, where is",
except that Sublessor has agreed to and shall provide, at no additional cost or
expense to Sublessee, a demising wall separating the Sublease Premises from
other space in the Building, in accordance with all applicable codes, but
otherwise as Sublessor deems appropriate. Sublessee has had the opportunity to
and has inspected the Sublease Premises, and Sublessor makes and has made no
representations or warranties whatsoever with respect to the Sublease Premises
or the fitness thereof for Sublessee's intended purpose.

         (b) Sublessee hereby acknowledges and agrees that Sublessee has had the
opportunity of and has reviewed the Prime Lease. Sublessor makes no
representations or warranties about said Prime Lease or its current status,
except as provided herein.

14. Brokerage. CB COMMERCIAL REAL ESTATE GROUP, INC. ("CB") HAS ACTED AS AGENT
FOR SUBLESSOR IN THIS TRANSACTION. THE WESLEY COMPANY HAS ACTED AS AGENT FOR
SUBLESSEE IN THIS TRANSACTION. CB AND THE WESLEY COMPANY SHALL EACH BE PAID A
COMMISSION BY SUBLESSOR AS INDICATED IN EXHIBIT "D". Sublessor and Sublessee
hereby covenant and agree to one another that no brokerage fees or commissions
are due with respect to or in conjunction with this Sublease as a result of such
party having dealt with any broker other than CB or THE WESLEY COMPANY.
Sublessor and Sublessee hereby indemnify one another, and hold one another
harmless, from and against all loss, cost, damage or expense, including, but not
limited to, attorney's fees and court costs, incurred by a party hereto as a
result of any claims for brokerage fees or commissions due which are made by
reason of such party having dealt with any broker (other than CB or THE WESLEY
COMPANY). Sublessee shall cause any agent or broker representing Sublessee to
execute a lien waiver to and for the benefit of Sublessor and Prime Landlord,
upon receipt by such agent or broker of any commission due hereunder, waiving
any and all lien rights with respect to the Building or Property such agent or
broker has or might have under Georgia law.

therein, such insurance coverage to be equal to the full replacement value of
such improvements and property, as such may increase from time to time; (ii)
worker's compensation insurance required by the State of Georgia; and (iii)
commercial general liability coverage on an occurrence basis for injury to or
death of a person or persons and for damage to property occasioned by or arising
out of the condition, use, or occupancy of the Sublease Premises, or other
portions of the Building, including contractual liability and such other
coverages and endorsements as are reasonably required by Sublessor, such policy
to have a combined single limit of not less than Three Million and No/100
Dollars ($3,000,000) for any bodily injury or property damage occurring as a
result of or in connection with the above. Prime Landlord, Sublessor and
Sublessor's property manager shall be named additional insureds on the policies
required hereunder and such policies shall provide that the coverage thereunder
is primary to, and not contributing with, any policy carried by any such
additional insured.

         (b) Sublessee shall have included in all policies of insurance
respectively obtained by it with respect to the Building or Sublease Premises a
waiver by the insurer of all right of subrogation against the Sublessor in
connection with any loss or damage thereby insured against, and Sublessor shall
have included in all property insurance policies required to be maintained by
Sublessor under this Sublease a waiver by the insurer of all right of
subrogation against the Sublessee in connection with any loss or damage thereby
insured against. To the full extent permitted by law, Sublessor as to its
property insurance policies and Sublessee as to all its policies, each waives
all right of recovery against the other for, and agrees to release the other
from liability for, loss or damage to the extent such loss or damage results
from a cause covered by valid and collectible insurance in effect at the time of
such loss or damage; provided however, that the foregoing release by each party
is conditioned upon the other party's carrying insurance with the above
described waiver of subrogation to the extent required above, and if such
coverage is not obtained or maintained by either party, then the other party's
foregoing release shall be deemed to be rescinded until such waiver is either
obtained or reinstated.

         (c) All said insurance policies shall be carried with companies
licensed to do business in the State of Georgia reasonably satisfactory to
Sublessor having a Best's Rating of A XII or better and shall be noncancellable
and nonamendable except after thirty (30) days' written notice to Sublessor. At
Sublessor's request, duly executed certificates of such insurance shall be
delivered to Sublessor prior to the Commencement Date and at least thirty (30)
days prior to the expiration of each respective policy term. Sublessor shall
have the right to periodically review the coverages required hereunder and if
Sublessor deems it reasonably necessary to require additional coverage resulting
from inflation or from increases in jury verdicts or other economic conditions
in the jurisdiction where the Property is located, Sublessee shall obtain the
coverage requested by Sublessor.

16. Sublessee's Care Of The Sublease Premises.

         (a) Sublessee will maintain the Sublease Premises and the fixtures and
appurtenances therein in at least the same condition that existed on the
Commencement Date, and will not commit


                                      -6-

or permit waste therein. Any repair work, maintenance and any alterations
permitted by Sublessor in the Sublease Premises (i) shall be done at Sublessee's
sole cost and expense; (ii) shall be done by Sublessor's employees or agents or,
with Sublessor's consent, by persons requested by Sublessee; and (iii) shall
first be consented to by Sublessor. Sublessee shall, at Sublessee's expense, but
under the direction of Sublessor and performed by Sublessor's employees or
agents, or with Sublessor's consent, by persons requested by Sublessee and
consented to by Sublessor, promptly repair any injury or damage to the Sublease
Premises or Building caused by the misuse or neglect thereof by Sublessee, by
Sublessee's contractors, subcontractors, customers, employees, licensees,
agents, or invitees.

         (b) Sublessee will not, without Sublessor's prior consent, and, as
applicable under the Prime Lease, without the prior consent of Prime Landlord,
make alterations, additions or improvements (including, but not limited to,
structural alterations, additions or improvements) in or about Sublease Premises
and will not do anything to or on the Sublease Premises which will increase the
rate of insurance on the Building or the Property. All alterations, additions or
improvements of a permanent nature made or installed by Sublessee to the
Sublease Premises shall become the property of Sublessor at the expiration or
early termination of this Lease. Sublessor reserves the right to require
Sublessee to remove any improvements or additions made to the Sublease Premises
by Sublessee and to repair and restore the Sublease Premises to their condition
prior to such alteration, addition or improvement, reasonable wear and tear,
unrepaired casualty and condemnation excepted, unless Sublessor and, if
applicable, Prime Landlord, has agreed at or prior to the time Sublessee
requests the right to make such alteration, addition or improvement that such
item need not be removed by Sublessee at the expiration or early termination of
the Term.

         (c) No later than the last day of the Term, Sublessee will remove
Sublessee's personal property and repair injury done by or in connection with
installation or removal of said property and surrender the Sublease Premises
(together with all keys, access cards or entrance passes to the Sublease
Premises and/or the Building) in as good a condition at the beginning of the
Term, reasonable wear and tear, unrepaired casualty and condemnation excepted.
All property of Sublessee remaining in the Sublease Premises after expiration or
early termination of the Term shall be deemed conclusively abandoned and may be
removed by Sublessor, and Sublessee shall reimburse Sublessor for the cost of
removing the same, subject however, to Sublessor's right to require Sublessee to
remove any improvements or additions made to the Sublease Premises by Sublessee
pursuant to the preceding Paragraph.

         (d) In doing any work on the installation of Sublessee's furnishings,
fixtures, or equipment in the Sublease Premises, Sublessee will use only
contractors or workers consented to by Sublessor prior to the time such work is
commenced. The foregoing sentence shall not apply to any internal wiring or
cabling in the Sublease Premises, so long as such work is done in accordance
with all applicable codes and legal requirements. Sublessor may condition its
consent upon its receipt from such contractors or workers of acceptable (i) lien
waivers; and (ii) evidence of liability and personal property insurance coverage
in amounts and with insurance carriers satisfactory to Sublessor. Sublessee
shall promptly remove any lien or claim of lien for material or labor claimed
against the Sublease Premises or Building, or both, by such contractors or
workers if such claim should arise, and hereby indemnifies and holds Sublessor
harmless from and against any and all loss, cost, damage, expense or liabilities
including, but not limited to, attorney's fees, incurred by Sublessor, as a
result of or in any way related to such claims or liens.

         (e) All personal property brought into the Sublease Premises by
Sublessee, its employees, licensees and invitees shall be at the sole risk of
Sublessee, and Sublessor shall not be liable for theft thereof or of money
deposited therein or for any damages thereto, such theft or damage being the
sole responsibility of Sublessee, unless arising out of the gross negligence or
willful misconduct of Sublessee.

17. Default By Sublessee; Sublessor's Remedies.

         (a) The occurrence of any of the following shall constitute an Event of
Default hereunder by Sublessee:

                  (i)      The Rent or any other sum of money due of Sublessee
                           hereunder is not paid within five (5) business days
                           of the effective date of notice of such late payment;

                  (ii)     The Sublease Premises are abandoned or vacated;

                  (iii)    Any petition is filed by or against Sublessee under
                           any section or chapter of the National or Federal
                           Bankruptcy Act or any other applicable Federal or
                           State bankruptcy, insolvency or other similar law,
                           and, in the case of a petition filed against
                           Sublessee, such petition is not dismissed within
                           ninety (90) days after the date of such filing; if
                           Sublessee shall become insolvent or transfer property
                           to defraud creditors; if Sublessee shall make an
                           assignment for the benefit of creditors; or if
                           receiver is appointed for any of Sublessee's assets;

                  (iv)     Sublessee fails to bond off or otherwise remove any
                           lien filed against the Sublease Premises or the
                           Building by reason of Sublessee's actions, within
                           fifteen (15) business days after Sublessee has notice
                           of the filing of such lien;

                  (v)      Sublessee fails to observe, perform and keep the
                           covenants, agreements, provisions, stipulations,
                           conditions and Rules herein contained to be observed,
                           performed and kept by Sublessee (other than the
                           failure to pay when due any Rent or any other sum of
                           money becoming due Sublessor hereunder, which under
                           all circumstances is governed by and subject to
                           Paragraph 17(a)(i) herein), and persists in such
                           failure after fifteen (15) days written notice by
                           Sublessor requiring that Sublessee remedy, correct,
                           desist or comply (or if any such failure to comply on
                           the part of Sublessee would reasonably require more
                           than fifteen (15) days to rectify, unless Sublessee
                           commences rectification within the fifteen (15) day
                           notice period and thereafter promptly, effectively
                           and continuously proceeds with the rectification of
                           the failure to comply on the part of Sublessee and,
                           in all such events, cures such failure to comply on
                           the part of Sublessee no later than ninety (90) days
                           after such notice).

         (b) Upon the occurrence of an Event of Default, Sublessor shall have
the option to do and perform any one or more of the following:

                  (i)      Terminate this Sublease, in which event Sublessee
                           shall immediately surrender the Sublease Premises to
                           Sublessor. If Sublessee shall fail to do so,
                           Sublessor may, without further notice and without
                           prejudice to any other


                                      -8-
<PAGE>   9

                           remedy Sublessor may have, enter upon the Sublease
                           Premises as permitted by law, without the requirement
                           of resorting to the dispossessory procedures set
                           forth in O.C.G.A.SectionSection44-7-50 et seq. and
                           expel or remove Sublessee and Sublessee's effects
                           without being liable for any claim for trespass or
                           damages therefor. Upon any such termination,
                           Sublessee shall remain liable to Sublessor for
                           damages, due and payable monthly on the day Rent
                           would have been payable hereunder, in an amount equal
                           to the Rent and any other amounts which would have
                           been owing by Sublessee for the balance of the Term,
                           had this Sublease not been terminated, less the net
                           proceeds, if any, of any reletting of the Sublease
                           Premises by Sublessor, after deducting all of
                           Sublessor's costs and expenses (including, without
                           limitation, advertising expenses and professional
                           fees) incurred in connection with or in any way
                           related to the termination of this Sublease, eviction
                           of Sublessee and such reletting; and/or

                  (ii)     Declare the entire amount of Rent calculated on the
                           current rate being paid by Sublessee, and other sums
                           which would become due and payable during the
                           remainder of the Term, discounted to present value by
                           using a reasonable discount rate selected by
                           Sublessor, to be due and payable immediately. Upon
                           such acceleration of such amounts, Sublessee agrees
                           to pay the same at once, together with all Rent and
                           other amounts theretofore due, less the market value
                           of the Sublease Premises for the remainder of the
                           Term, as reasonably determined by Sublessor (taking
                           into consideration the probable costs of marketing
                           and reletting the Sublease Premises, then-current
                           rental rates, probable rental rates for the remainder
                           of the Term, probable concession packages, the
                           probability of reletting the Sublease Premises and
                           the probable amount of time which will elapse before
                           the Sublease Premises are relet), at Sublessor's
                           address as provided herein; provided however, that
                           such payment shall not constitute a penalty or
                           forfeiture but shall constitute liquidated damages
                           for Sublessee's failure to comply with the terms and
                           provisions of this Sublease (Sublessor and Sublessee
                           agreeing that Sublessor's actual damages in such an
                           event are impossible to ascertain and that the amount
                           set forth above is a reasonable estimate thereof).
                           The acceptance of such payment by Sublessor shall not
                           constitute a waiver of rights or remedies to
                           Sublessor for any failure of Sublessee thereafter
                           occurring to comply with any term, provision,
                           condition or covenant of this Sublease; and/or

                  (iii)    Enter the Sublease Premises as permitted by law,
                           without the requirement of resorting to the
                           dispossessory procedures set forth in
                           O.C.G.A.SectionSection44-7-50 et seq. and without
                           being liable for any claim for trespass or damages
                           therefor, and, in connection therewith, rekey the
                           Sublease Premises, remove Sublessee's effects
                           therefrom and store the same at Sublessee's expense,
                           without being liable for any damage thereto, and
                           relet the Sublease Premises as the agent of
                           Sublessee, without advertisement, by private
                           negotiations, for any term Sublessor deems proper,
                           and receive the rent therefor. Sublessee shall pay
                           Sublessor on demand any deficiency that may arise by
                           reason of


                                      -9-
<PAGE>   10

                           such reletting, but Sublessee shall not be entitled
                           to any surplus so arising. Sublessee shall reimburse
                           Sublessor for all costs and expenses (including,
                           without limitation, advertising expenses and
                           professional fees) incurred in connection with or in
                           any way related to the eviction of Sublessee and
                           reletting the Sublease Premises, and for the amount
                           of any other Rent which would have been due of
                           Sublessee to Sublessor hereunder if not for certain
                           concessions granted by Sublessor to Sublessee.
                           Sublessor, in addition to but not in lieu of or in
                           limitation of any other right or remedy provided to
                           Sublessor under the terms of this Sublease or
                           otherwise (but only to the extent such sum is not
                           reimbursed to Sublessor in conjunction with any other
                           payment made by Sublessee to Sublessor), shall have
                           the right to be immediately repaid by Sublessee the
                           amount of all sums expended by Sublessor and not
                           repaid by Sublessee in connection with preparing or
                           improving the Sublease Premises to Sublessee's
                           specifications and any and all reasonable costs and
                           expenses incurred in renovating or altering the
                           Sublease Premises to make it suitable for reletting;
                           and/or

                  (iv)     Do whatever Sublessee is obligated to do under this
                           Sublease, including, but not limited to, entering the
                           Sublease Premises, without being liable to
                           prosecution or any claims for damages, in order to
                           accomplish this purpose. Sublessee agrees to
                           reimburse Sublessor immediately upon demand for any
                           reasonable expenses which Sublessor may incur in thus
                           effecting compliance with this Lease on behalf of
                           Sublessee. Sublessor shall not be liable for any
                           damages resulting to Sublessee from such action,
                           whether caused by the negligence of Sublessor or
                           otherwise.

         (c) Pursuit by Sublessor of any of the foregoing remedies shall not
preclude the pursuit of general or special damages incurred, or of any of the
other remedies provided herein, at law or in equity.

         (d) No act or thing done by Sublessor or Sublessor's employees or
agents during the Term shall be deemed an acceptance of a surrender of the
Sublease Premises. Neither the mention in this Sublease of any particular
remedy, nor the exercise by Sublessor of any particular remedy hereunder, at law
or in equity, shall preclude Sublessor from any other remedy Sublessor might
have under this Sublease, at law or in equity. Any waiver of or redress for any
violation of any covenant or condition contained in this Sublease or any of the
Rules now or hereafter adopted by Sublessor, shall not prevent a subsequent act,
which would have originally constituted a violation, from having all the force
and effect of an original violation. The receipt by Sublessor of Rent with
knowledge of the breach of any covenant in this Sublease shall not be deemed a
waiver of such breach.

18. Condemnation. If the Sublease Premises, or a part of such Sublease Premises
(comprising at least ten percent (10%) of the rentable square feet therein) such
that the Sublease Premises are unusable, are taken by eminent domain or other
similar proceeding or are conveyed in lieu of such taking, then at the option of
either Sublessor or Sublessee, such option to be exercised, if at all, within
thirty (30) days after the party first has knowledge of the condemnation, this
Sublease shall expire on the date when title or right of possession vests, and
Rent paid for any period beyond said


                                      -10-
<PAGE>   11

date shall be repaid to Sublessee. If there is a partial taking where this
Sublease is not terminated, the Rent shall be adjusted in proportion to the
square feet of Sublease Premises taken, determined by Sublessor. In either
event, Sublessor shall be entitled, and Sublessee shall not have any right, to
claim any award made in any condemnation proceeding, action or ruling relating
to the Building or the Property; provided, however, Sublessee shall be entitled
to make a claim in any condemnation proceeding, action or ruling relating to the
Building for Sublessee's moving and relocation expenses and the unamortized
value of leasehold improvements in the Sublease Premises actually paid for by
Sublessee, to the extent such claim does not in any manner impact upon or reduce
Sublessor's claim or award in such condemnation proceeding, action or ruling.
Sublessor shall have, in Sublessor's sole discretion, the option of terminating
this Sublease if any such condemnation, action, ruling or conveyance in lieu
thereof makes continuation of Sublessor's use of the Building economically
unfeasible.

19. Inspections. Sublessor, its agents or employees may enter the Sublease
Premises at reasonable hours, upon reasonable notice (except in an emergency,
for which no notice shall be required), to (a) exhibit the Sublease Premises to
prospective purchasers or, during the last six (6) months of the Term or if an
Event of Default on the part of Sublessee has occurred and is continuing,
sublessees or other potential occupants of the Sublease Premises or the
Building; (b) inspect the Sublease Premises to see that Sublessee is complying
with its obligations hereunder; and (c) make repairs (i) required of Sublessor
under the terms hereof; (ii) to any adjoining space in the Building; or (iii) to
any systems serving the Building which run through the Sublease Premises.
Sublessor shall endeavor to conduct any such inspections or entries in the
Sublease Premises in such a manner as to not unreasonably disrupt or interrupt
Sublessee's operations in the Sublease Premises.

20. Subordination.

         (a) This Sublease shall be subject and subordinate to the Prime Lease
and to any underlying land leases or deeds to secure debt which may now or
hereafter affect this Lease, the Building or the Property and also to all
renewals, modifications, extensions, consolidations, and replacements of such
underlying land leases and such deeds to secure debt. In confirmation of the
subordination set forth in this Paragraph 20, Sublessee shall, at Sublessor's
request, execute and deliver such further instruments as may be desired by the
holder of the deed to secure debt (a "Mortgagee") or by any lessor under any
such underlying land leases. Notwithstanding the foregoing, Sublessor or such
Mortgagee shall have the right to subordinate or cause to be subordinated, in
whole or in part, any such underlying land leases or deeds to secure debt to
this Sublease (but not in respect to priority of entitlement of insurance or
condemnation proceeds). If any such underlying land leases or deeds to secure
debt terminate for any reason or any such deeds to secure debt are foreclosed or
a conveyance in lieu of foreclosure is made for any reason, Sublessee shall,
notwithstanding any subordination, deliver to Mortgagee within ten (10) days of
written request an attornment agreement, providing that such Sublessee shall
continue to abide by and comply with the terms and conditions of this Sublease.

         (b) If any proceedings are brought for the foreclosure of, or in the
event of exercise of the power of sale or conveyance in lieu of foreclosure
under any deed to secure debt, Sublessee shall at the option of the purchaser at
such foreclosure or other sale, attorn to such purchaser and recognize such
person as Sublessor under this Sublease. The institution of any suit, action or
other


                                      -11-
<PAGE>   12

proceeding by a Mortgagee or a sale of the Sublease Property pursuant to the
powers granted to a Mortgagee under its deed to secure debt, shall not, by
operation of law or otherwise, result in the cancellation or the termination of
this Sublease or of the obligations of Sublessee hereunder.

         (c) If such purchaser requests and accepts such attornment, from and
after such attornment, Sublessee shall have the same remedies against such
purchaser for the breach of an agreement contained in this Lease that Sublessee
might have had against Sublessor if the deed to secure debt had not been
terminated or foreclosed, except such purchaser shall not be (i) liable for any
act or omission of the prior Sublessor; (ii) subject to any offsets or defenses
which Sublessee might have against the prior Sublessor; or (iii) bound by any
Rent or security deposit which Sublessee might have paid in advance to the prior
Sublessor.

21. Indemnification And Hold Harmless.

         (a) Sublessee hereby indemnifies, agrees to defend and holds Sublessor
harmless from and against any injury, expense, damage, liability or claim,
imposed on Sublessor by any person whomsoever, whether due to damage to the
Sublease Premises, claims for injuries to the person or property of any other
Sublessee of the Building or of any other person in or about the Building for
any purpose whatsoever, or administrative or criminal action by a governmental
authority, provided such injury, expense, damage, liability or claim results
either directly or indirectly from the act, omission, negligence, misconduct or
breach of any provisions of this Sublease by Sublessee, the agents, contractors,
or employees of Sublessee, or any other person entering upon the Sublease
Premises under express or implied invitation or consent of Sublessee, and
provided further that in assessing Sublessee's liability hereunder, the
negligence (if any) of Sublessor associated with such occurrence or incident
shall be taken into account. Sublessee further agrees to reimburse Sublessor,
its agents, contractors or employees or Sublessor's property manager for any
reasonable costs or expenses, including, but not limited to, court costs and
reasonable attorney's fees, which Sublessor or Sublessor's property manager may
incur in investigating, handling or litigating any such claim or any action by a
governmental authority.

         (b) Sublessee shall give notice to Sublessor of any defective condition
in or about the Sublease Premises known to Sublessee, and further agrees to
attempt to contact Sublessor by telephone reasonably promptly, or if such
condition is, in Sublessee's reasonable judgment, dangerous, immediately in such
instance.

22. Taxes on Sublessee's Property. Sublessee shall be liable for all taxes
levied or assessed against personal property, furniture or fixtures placed by
Sublessee in the Sublease Premises (herein called "Sublessee's Property"). If
any such taxes for which Sublessee is liable are levied or assessed against
Sublessor or Sublessor's property and if Sublessor elects to pay the same, after
notice to Sublessor, or if the assessed value of Sublessor's Property is
increased as a result of inclusion of Sublessee's Property, and Sublessor elects
to pay the taxes based on such increase, Sublessee shall pay to Sublessor upon
demand and evidence of payment that part of such taxes for which Sublessee is
primarily liable hereunder.

23. Mechanic's Lien. In the case of the filing of any mechanic's lien upon the
Sublease Premises, the Building or any improvements thereon during the Term
caused by or resulting from any work performed, materials furnished or
obligation incurred by or at the request of Sublessee, Sublessee will promptly
pay, post an adequate bond or otherwise discharge the same. If default in


                                      -12-
<PAGE>   13

payment or discharge thereof, or failure to post bond, shall continue for thirty
(30) days after notice thereto from Sublessor to Sublessee, Sublessor shall have
the right and privilege at Sublessor's option, in addition to and not in lieu of
any other remedies available to Sublessee hereunder, of bonding off said lien.
In such event, any amounts so paid, including expenses and interest, shall be so
much Rent hereunder due from Sublessee to Sublessor and shall be repaid to
Sublessor immediately on demand.

24. Remedies Cumulative. The rights given to Sublessor and Sublessee herein are
in addition to any rights that may be given to Sublessor or Sublessee by any
statute or under law.

25. Entire Agreement-No Waiver. This Sublease contains the entire agreement of
the parties hereto and no representations, inducements, promises or agreements,
oral or otherwise, between the parties not embodied herein shall be of any force
and effect. The failure of either party to insist in any instance on strict
performance of any covenant or condition hereof, or to exercise any option
herein contained, shall not be construed as a waiver of such covenant, condition
or option in any other instance. This Sublease cannot be changed or terminated
orally, and can be modified only in writing, executed by each party hereto.

26. Holding Over. If Sublessee remains in possession of the Sublease Premises
after expiration of the Term, or after any termination of the Sublease by
Sublessor, with Sublessor's acquiescence and without any written agreement
between the parties, Sublessee shall be a tenant at sufferance and such tenancy
shall be subject to all the provisions hereof, except that the Monthly Rental
for said holdover period shall be one hundred fifty percent (150%) of the amount
of Rent due in the last month of the Term, for the first three (3) months of any
such holdover, and then double the amount of such Rent thereafter. There shall
be no renewal of this Sublease by operation of law. Nothing in this Paragraph
shall be construed as a consent by Sublessor to the possession of the Sublease
Premises by Sublessee after the expiration of the Term or any termination of the
Sublease by Sublessor.

27. Estoppel Certificates. (a) Sublessee shall furnish from time to time when
requested by Sublessor or the holder of any deed to secure debt or mortgage
covering all or any part of the Building or the improvements therein or the
Sublease Premises or any interest of Sublessor therein, a certificate signed by
Sublessee confirming and containing the following factual certifications: (i)
this Sublease is unmodified and in full force and effect (or if there shall have
been modifications that this Sublease is in full force and effect as modified
and stating such modifications); (ii) the dates to which all rental and other
charges have been paid and whether any such payment represents payment in
advance; and (iii) to the best knowledge of Sublessee no default of the other
party in the performance of any covenant, agreement or condition has occurred
and remains uncured or has been waived or, if default has occurred, the steps
being taken, if any, to cure or correct the same, and Sublessee shall, within
fifteen (15) days following receipt of said proposed certificate from Sublessor,
return a fully executed copy of said certificate to Sublessor.

         (b) Sublessor shall furnish from time to time when requested by
Sublessee, a certificate signed by Sublessor confirming and containing the
following factual certifications: (i) this Sublease is unmodified and in full
force and effect (or if there shall have been modifications that this Sublease
is in full force and effect as modified and stating such modifications); (ii)
the dates to which all rental and other charges have been paid and whether any
such payment represents payment in advance; and (iii) to the best knowledge of
Sublessor no default of the other party in the


                                      -13-
<PAGE>   14

performance of any covenant, agreement or condition has occurred and remains
uncured or has been waived or, if default has occurred, the steps being taken,
if any, to cure or correct the same, and Sublessor shall, within fifteen (15)
days following receipt of said proposed certificate from Sublessee, return a
fully executed copy of said certificate to Sublessee.

28. Other Charges. If Sublessor is charged for additional rent or any other sums
pursuant to the provisions of the Prime Lease, as a result of or in connection
with requests made or actions taken by Sublessee, including, but not limited to,
Article II thereof, Sublessee shall be liable for Sublessee's Share of such
additional rent or other sums, unless such charge arises out of the acts or
failure to act (where action is required) of Sublessor. If Sublessee shall
procure any additional services from the Building, such as alterations or
after-hour air conditioning, Sublessee shall pay for same at the rates charged
therefor by the Prime Landlord and shall make such payment to the Sublessor or
Prime Landlord, as Sublessor shall direct. If payment is made to Sublessor,
Sublessor shall be liable to Prime Landlord for such charges and shall indemnify
and hold harmless Sublessee against any claim by Prime Landlord, for payment.
Any sums payable by Sublessee under this Paragraph shall be additional Rent and
collectible by Sublessor as such. If Sublessor receives any refund from Prime
Landlord, Sublessee shall be entitled to the return of so much thereof as shall
be attributable to prior payments by Sublessee.

29. Headings. The headings in this Sublease are included for convenience only
and shall not be taken into consideration in any construction or interpretation
of any part of this Sublease.

30. Attorney's Fees. If Sublessor has to engage or consult with an attorney as a
result of or in connection with a failure by Sublessee to pay any Rent as and
when due under the Sublease, then Sublessee shall owe to Sublessor, in addition
to and not in lieu of any other amounts due hereunder, and shall pay within ten
(10) days after demand for payment therefor is made, all such attorneys fees
incurred by Sublessor. Also, if any law suit or court action between Sublessor
and Sublessee arises out of or under this Sublease, the prevailing party in such
law suit or court action shall be entitled to and shall collect from the
non-prevailing party the reasonable attorney's fees and court costs actually
incurred by the prevailing party with respect to said lawsuit or court action.

31. Time Of Essence.  TIME IS OF THE ESSENCE OF THIS SUBLEASE.

32. No Estate In Land. Sublessee has only a usufruct under this Sublease, not
subject to levy or sale. No estate shall pass out of Sublessor by this Sublease.

33. Services. (a) Except as otherwise provided herein, the only services or
rights to which Sublessee is entitled hereunder are those to which Sublessor is
entitled to as "Tenant" under the Prime Lease, and Sublessee shall be entitled
to all such services or rights. For all such services and rights Sublessee will
look to Prime Landlord under the Prime Lease. Notwithstanding the foregoing
sentence, unless consented to by Sublessor, Sublessee shall not contact Prime
Landlord directly, but instead shall request that Sublessor do so, if Sublessee
is not receiving services from Prime Landlord as provided for in the Prime
Lease.

         (b) Supplementing Paragraph 8 of this Sublease, the following services
are (by way of illustration but not limitation) available and shall be provided
to the Sublease Premises and are included in the Base Rent:

                  1.       Halon and other specialized fire protection systems.


                                      -14-
<PAGE>   15

                  2.       Uninterruptable Power Systems, generators, power
                           distribution units, and batteries.

                  3.       24-hours per day, 7 days per week, HVAC systems

                  4.       Raised, computer flooring

                  5.       Special security or monitoring systems

                  6.       Janitorial Service

                  7.       Elevator Service

34. No Acts. Neither party shall do nor permit anything to be done which would
cause the Prime Lease to be terminated or forfeited or any claims to accrue to
the benefit of Prime Landlord by reason of any right of termination or
forfeiture reserved or vested in Prime Landlord under the Prime Lease, or any
rights to damages accruing to or for the benefit of Prime Landlord under the
Prime Lease, and each party shall indemnify, agree to defend and hold the other
party harmless from and against all loss, cost, damage or expense, including,
but not limited to, attorney's fees and court costs, incurred by such party by
reason of any default on the part of the other party by reason of which the
Prime Lease may be terminated or forfeited, or any claims shall accrue to the
benefit of or for Prime Landlord under the Prime Lease. Notwithstanding the
above, if Sublessee fails to make a payment when due hereunder, then Sublessor
may not, in turn, fail to pay Prime Landlord the rent due under the Prime Lease,
and make a claim against Sublessee hereunder that Sublessee, by virtue of such
non-payment, has caused a default under the Prime Lease. Sublessor shall provide
to Sublessee in a reasonably prompt manner any notice received by Sublessor from
Prime Landlord of a default under the Prime Lease to the extent such default
relates to the Sublease Premises and events, occurrences or actions arising
therefrom or therein.

35. Parking Arrangements. Sublessor shall maintain parking spaces on the
Property for use by Sublessee and Sublessee's invitees and employees, on an
unreserved and non-exclusive basis in the ratio 4.0 parking passes per 1000
rentable square feet of office space leased by Sublessee, and Sublessee shall
use no more than said amount of parking spaces. Such parking shall be available
subject to the limitations and conditions from time to time imposed by
Sublessor.

36. Rules And Regulations. The Rules on Exhibit "E" are a part of this Sublease.
Sublessor may from time to time reasonably amend, modify, delete or add
additional Rules for the use, operation, safety, cleanliness and care of the
Sublease Premises and the Building. Such new or modified Rules shall be
effective upon notice to Sublessee. Sublessee will cause its employees and
agents, or any others permitted by Sublessee to occupy or enter the Sublease
Premises to at all times abide by the Rules. If there is a breach of any Rules,
Sublessor shall have all remedies in this Sublease provided for in an Event of
Default by Sublessee. Sublessor shall not be responsible to Sublessee for the
nonobservance by any other Sublessee or person of any such Rules.

37. Late Payments. Any payment due of Sublessee hereunder not received by
Sublessor within five (5) days of the date when due shall be assessed a five
percent (5%) charge for Sublessor's administrative and other costs in processing
and pursuing the payment of such late payment, and shall be assessed an
additional five percent (5%) charge for the aforesaid costs of Sublessor for
each month thereafter until paid in full; provided, however, that the aforesaid
five percent (5%) charge shall not be due the 1st time in any twelve (12) month
period that a payment is not made when due


                                      -15-
<PAGE>   16

by Sublessee, unless such payment is not made within five (5) days after notice
that such payment has not been made is given to Sublessee. Acceptance by
Sublessor of a payment, and the cashing of a check, in an amount less than that
which is currently due shall in no way affect Sublessor's rights under this
Sublease and in no way be an accord and satisfaction. This provision does not
prevent Sublessor from declaring the non-payment of Rent when due an event of
default hereunder.

38. Severability And Interpretation.

         (a) if any clause or provision of this Sublease shall be deemed
illegal, invalid or unenforceable under present or future laws effective during
the Term, the remainder of this Sublease shall not be affected by such
illegality, invalidity or unenforceability, and in lieu of each clause or
provision of this Sublease that is illegal, invalid or unenforceable, there
shall be added as a part of this Lease a clause or provision as similar in terms
to such illegal, invalid or unenforceable clause or provision as may be possible
and be legal, valid and enforceable.

         (b) If any provisions of this Sublease require judicial interpretation,
the court interpreting or construing the same shall not apply a presumption that
the terms of any such provision shall be more strictly construed against one
party or the other by reason of the rule of construction that a document is to
be construed most strictly against the party who itself or through its agent
prepared the same, as all parties hereto have participated in the preparation of
this Sublease.

39. Multiple Sublessees. If more than one individual or entity comprises and
constitutes Sublessee, then all individuals and entities comprising Sublessee
are and shall be jointly and severally liable for the due and proper performance
of Sublessee's duties and obligations arising under or in connection with this
Sublease.

40. Force Majeure. Sublessor and Sublessee shall be excused for the period of
any delay and shall not be deemed in default with respect to the performance of
any of the terms, covenants, and conditions of this Sublease when prevented from
so doing by causes beyond Sublessor's and Sublessee's respective, reasonable
control, which shall include, but not be limited to, all labor disputes,
governmental regulations or controls, fire or other casualty, inability to
obtain any material or services, or acts of God; provided however, in no event
and under no circumstances shall an inability or failure to pay money be
attributable to or be excused by any of the matters set forth above.

41. Quiet Enjoyment. So long as an Event of Default on the part of Sublessee has
not occurred and is continuing, Sublessor shall warrant and defend Sublessee in
the quiet enjoyment and possession of the Sublease Premises during the Term
against any and all claims made by, through or under Sublessor, subject to the
terms of this Sublease.

42. Exculpation Of Sublessor. Sublessor's liability to Sublessee with respect to
this Sublease shall be limited solely to Sublessor's interest in the Building.
Neither Sublessor nor any of the partners of Sublessor nor any officer,
director, or shareholder of Sublessor shall have any personal liability
whatsoever with respect to this Sublease. No partners of Sublessee, nor any
officer, director, or shareholder of Sublessee shall have any personal liability
whatsoever with respect to the Sublease.

43. Original Instrument. Any number of counterparts of this Sublease may be
executed, and each such counterpart shall be deemed to be an original
instrument.


                                      -16-
<PAGE>   17

44. Georgia Law. This Sublease has been made under and shall be construed and
interpreted under and in accordance with the laws of the State of Georgia.

45. No Recordation Of Sublease. Without the prior consent of Sublessor, neither
this Sublease nor any memorandum hereof shall be recorded or placed on public
record.

46. Hazardous Wastes.

         (a) Sublessee shall not (either with or without negligence) cause or
permit the escape, disposal or release of any biologically or chemically active
or other hazardous substances or materials. Sublessee shall not allow the
storage or use of such substances or materials in any manner not sanctioned by
law, nor allow to be brought into the Building, the Sublease Premises or the
Property, any such materials or substances except to use in the ordinary course
of Sublessee's business, and then only if such are "Permitted Hazardous
Substances" (as that term is herein defined). Without limitation, hazardous
substances and materials shall include those described in the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, 42
U.S.C. Section 9601 et seq., the Resource Conservation and Recovery Act, as
amended, 42 U.S.C. Section 6901 et seq., any applicable state or local laws and
the regulations adopted under these acts. If any lender or governmental agency
shall ever require testing to ascertain whether or not there has been any
release of hazardous materials, then the reasonable costs thereof shall be
reimbursed by Sublessee to Sublessor upon demand as additional charges if such
requirement applies to the Sublease Premises. In addition, Sublessee shall
execute affidavits, representations and the like from time to time at
Sublessor's request concerning Sublessee's best knowledge and belief regarding
the presence of hazardous substances or materials on the Sublease Premises. In
all events, Sublessee shall indemnify Sublessor in the manner elsewhere provided
in this Sublease from any release of hazardous materials on the Sublease
Premises occurring while Sublessee is in possession, or elsewhere if caused by
Sublessee or persons acting under Sublessee. The within covenants shall survive
the expiration or earlier termination of the Term.

         (b) As used herein, the term "Hazardous Material" means any hazardous
or toxic substance, material, or waste which is or becomes regulated as such by
any local governmental authority or the United States Government. The term
"Hazardous Material" includes, without limitation, any material or substance
which is (i) defined as a "hazardous waste", "extremely hazardous waste", or
"restricted hazardous waste" or similar term under the law of the jurisdiction
where the property is located, or (ii) designated as a "hazardous substance"
pursuant to Section 311 of the Federal Water Pollution Control Act (33 U.S.C.
Section 1317), (iii) defined as a "hazardous waste" pursuant to Section 1004 of
the Federal Resource Conservation and Recovery Act, 47 U.S. Section 6901 et seq.
(42 U.S.C. Section 6903), or (iv) defined as a "hazardous substance" pursuant to
Section 101 of the Comprehensive Environmental Response, Compensation and
Liability Act, 42 U.S.C. Section 9601 et seq. (42 U.S.C. Section 9601).

         (c) The term "Permitted Hazardous Substances" shall mean such Hazardous
Substances as are commonly and legally used or stored as a consequence of using,
maintaining or operating the Sublease Premises, but only so long as the
quantities thereof do not pose a threat to public health or to the environment
or would necessitate a "response action" as that term is defined in CERCLA, and
so long as Landlord strictly complies or causes compliance with all applicable
governmental rules and regulations concerning the use, storage, production,
transportation and disposal of such Hazardous Substances.


                                      -17-
<PAGE>   18

         (d) The Sublease Premises and the Building have not to Sublessor's
knowledge, but without any independent investigation or inquiry of any nature or
kind, been used by Sublessor for the handling, treatment, storage or disposal of
any Hazardous Material; no Release (hereinafter defined) of any Hazardous
Material and no soil, water or air contamination by any Hazardous Material has
occurred or is occurring in, from or on the Sublease Premises or the Building;
Sublessor has not arranged for the disposal of any Hazardous Material on the
Sublease Premises or the Building; Sublessor has complied with all reporting
requirements under any applicable federal, state or local environmental laws and
permits as they relate to the Sublease Premises, and there are no existing
violations by the Sublessor of any such environmental laws or permits; there are
no claims, actions, suits, proceedings or investigations related to the
presence, release, production, handling, discharge, spillage, transportation or
disposal of any Hazardous Material or contamination of soil, water or air by any
Hazardous Material pending or threatened with respect to the Sublease Premises
or the Building or otherwise against Sublessor in any court or before any state,
federal or other governmental agency or private arbitration tribunal and there
is no basis for any such claim, and action, suit, proceeding or investigation;
and the Sublease Premises and the Building are free from radon contamination.
Release shall mean any spilling, leaking, pumping, pouring, emitting, emptying,
discharging, injecting, escaping, leaching, dumping, or disposing into the
environment (including the abandonment or discarding of barrels, containers, and
other closed receptacles containing any Hazardous Material).

         (e) In the event the presence of any Hazardous Material in the Building
or the soil or ground water on or under the Building caused by Sublessor has
resulted in any contamination of the Building or the soil or ground water on or
under the Building, Sublessor hereby indemnifies Sublessee from and against any,
and agrees to defend and hold Sublessee harmless from and against any and all
loss, damage, cost and/or expenses (including, without limitation, sums paid in
settlement of claims, attorneys' fees, consultant fees and expert fees) which
arise during or after the Term of this Sublease as a result therefrom. This
indemnification of Sublessee by Sublessor includes, without limitation, costs
incurred by Sublessee in connection with any investigation of site conditions or
any cleanup, remedial, removal, or restoration work required by any federal,
state, or local governmental agency or political subdivision because of
Hazardous Material present in the soil or ground water on or under the Building
which results from such a breach. If Sublessor is required by law to remediate
such condition, Sublessor shall do so in a manner which does not unreasonably
disrupt or interfere with Sublessee's use of the Sublease Premises.

47. Sublease Binding Upon Delivery. This Sublease shall not be binding until and
unless all parties have duly executed said Lease and a fully executed
counterpart of said Sublease has been delivered to Sublessee.

48. Omitted.

49. Maintenance of Building and Services. Sublessor shall, at Sublessee's
request, use all reasonable efforts to cause Prime Landlord to (i) maintain or
cause to be maintained and make or cause to be made all necessary repairs to the
Building as more fully described in the Prime Lease, including, without
limitation, the mechanical systems of the Sublease Premises and Building, and
all interior and exterior structural elements of the Sublease Premises and
Building, including, without limitation, the exterior doors, walls, windows,
glass, ceilings, floors, foundation, and roof; (ii) furnish or provide or cause
to be furnished or provided through Prime Landlord, to Sublessee


                                      -18-
<PAGE>   19

the services more fully described in the Prime Lease. Sublessor shall notify
Sublessee of any services or operations it has assumed, or at any time assumes,
under the Prime Lease.

50. Sublessor's Compliance with Prime Lease. Sublessor covenants and agrees to
comply with the terms of the Prime Lease and this Sublease. Sublessor covenants
and agrees to use its best efforts to enforce the Prime Lease for the benefit of
Sublessee and to take such actions in connection therewith as Sublessee may
reasonably request and, if Sublessor fails to do so, Sublessee may, upon ten
(10) days prior notice to Sublessor, elect to seek to enforce against Prime
Landlord the terms of the Prime Lease directly. Sublessor shall not cancel,
terminate or amend the Prime Lease which does not materially affect Sublessee,
without the prior written consent of Sublessee, which in the case of amendment
shall not be unreasonably withheld. Provided an Event of Default on the part of
Sublessee has not occurred and is continuing, Sublessor agrees to maintain the
Prime Lease in force during the Term of this Sublease and to pay rent to Prime
Landlord in accordance with the terms of the Prime Lease. Without limiting any
other right or remedy of Sublessee under this Sublease, if Prime Landlord seeks
to terminate the Prime Lease because of a default or alleged default by
Sublessor under the Prime Lease, Sublessor shall use its best efforts to
maintain the Prime Lease in full force and effect for the benefit of Sublessee
and/or to claim and pursue any right of redemption or relief from any forfeiture
of the Prime Lease (and as a consequence thereof any forfeiture of this
Sublease) to which Sublessor may be entitled at law or in equity. In furtherance
and not in limitation of the foregoing, after written notice, if it reasonably
appears that Sublessor will not cure any default under the Prime Lease within
the applicable grace period, Sublessee may cure any default at Sublessor's cost.
If Sublessee at any time, by reason of Sublessor's default, pays any sum to cure
any default, the sum so paid by Sublessee shall be immediately due from
Sublessor to Sublessee on demand and evidence of payment, and shall bear
interest at the "Default Rate" (as that term is herein defined) from the date
paid by Sublessee until Sublessee shall have been reimbursed by Sublessor. Said
sum, together with interest thereon, may be offset against the Rent. Sublessee
may exercise any or all other rights or remedies available at law or equity,
including, without limitation, the right to obtain restraining orders,
injunctions and decrees of specific performance.

51. Sublessor's Representations and Warranties. Sublessor represents and
warrants that, to Sublessor's best knowledge and belief, and solely in its
capacity as a "Tenant", and without any independent investigation or inquiry of
any nature or kind whatsoever by Sublessor:

         (a) No default on the part of Sublessor exists under the Prime Lease,
the Prime Lease is in full force and effect and all payments of rent and other
charges payable by Sublessor to Prime Sublessor under the Prime Lease are
current.

         (b) Sublessor holds a leasehold interest in and to the Sublease
Premises under the Prime Lease, and has full right and lawful authority to enter
into this Sublease.

52. Sublease Intended to Benefit Affiliates of Sublessor. Sublessor is entering
into this Sublease not only for its own benefit but also for the benefit of any
affiliates of, or with a common parent with, Sublessor, present and future, and
that each such affiliate of Sublessor or other party described above occupying
any portion of the Sublease Premises shall be a third-party beneficiary of this
Sublease (a "Benefited Party", or collectively the "Benefited Parties").
However, in no event shall any provision of this Sublease be construed as making
any affiliate of or party related to Sublessor liable for any rents or other
amounts due hereunder. Present affiliates of Sublessor include Alabama Power
Company, Georgia Power Company, Gulf Power Company, Mississippi Power Company,
Savannah Electric and Power Company, Southern Nuclear Operating Company,

                      FIRST AMENDMENT TO SUBLEASE AGREEMENT


         THIS FIRST AMENDMENT TO SUBLEASE AGREEMENT ("First Amendment") is made
as of this 15th day of December, 1998, between SOUTHERN COMPANY SERVICES, INC.,
having an office at 64 Perimeter Center East, Atlanta, Georgia 30346
("Sublessor"), and SAGE NETWORKS, INC., having an office at 64 Perimeter Center
East, Suite G-300, Atlanta, Georgia 30346 ("Tenant", hereinafter referred to as
"Sublessee").

                              W I T N E S S E T H:

         WHEREAS, Sublessor and Sublessee entered into that certain Sublease
Agreement, dated the 29th day of May, 1998 ("the "Sublease"), for space known as
Suite G-300 (the "Sublease Premises") located in that certain building known as
64A Perimeter Center, Atlanta, Georgia (the Building"); and

         WHEREAS, pursuant to the Sublease, Sublessee has notified Sublessor of
Sublessee's desire to sublease additional space in the Building; and

         WHEREAS, Sublessor and Sublessee desire to enter into this First
Amendment for the purpose of evidencing their mutual understanding and agreement
regarding the expansion of the Sublease Premises and certain other matters
relating thereto as set forth in this First Amendment;

         NOW, THEREFORE, for and in consideration of the mutual covenants and
agreements hereinafter contained, and for Ten and No/100ths Dollars ($10.00) and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, Sublessor and Sublessee, intending to be legally bound,
agree as follows:

1.       DEFINED TERMS. All terms used herein and denoted by their initial
         capitalization shall have the meanings set forth in the Sublease unless
         set forth herein to the contrary.

2.       DATA CENTER EXPANSION PREMISES. The approximately 7,240 rentable square
         feet in the Building leased to Sublessee pursuant to the Sublease is
         defined in the Sublease and in this First Amendment as the "Sublease
         Premises". As of the Data Center Expansion Premises Commencement Date
         (hereinafter defined), the Sublease Premises is expanded to include the
         approximate 8,500 rentable square feet of Data Center Space (the "Data
         Center Expansion Premises") on floor G2 of the Building as shown on the
         drawing attached as Exhibit "A".

         Adding the Data Center Expansion Premises increases the Sublease
         Premises to 15,740 rentable square feet. Sublessor and Sublessee agree
         the measurement of 8,500 rentable square feet of Data Center Expansion
         Premises represents Sublessor's estimate in accordance with preliminary
         Sublessee designs. On or before January 31, 1999, this First Amendment
         shall be reasonably modified to reflect the actual rentable square feet
         of the final design of the Data Center Expansion Premises, such
         modification to be mutually determined by Sublessor and Sublessee.
         Usable square
<PAGE>   2
         feet shall be measured according to the Standard Method for Measuring
         Area in Office Buildings, ANSI Z65.1-1996 (BOMA).

         Sublessee hereby subleases the Data Center Expansion Premises and the
         Temporary Office Space (as hereafter defined) on the same terms and
         conditions as the Sublease Premises except as otherwise set forth
         herein to the contrary; provided, however, Sublessee shall receive no
         concessions or allowance on account of subleasing the Data Center
         Expansion Premises, except as specifically set forth in this First
         Amendment. Among those same terms and conditions of the Sublease which
         shall apply to the Data Center Expansion Premises, but not in
         limitation thereof, shall be Sublessee's renewal rights set forth in
         Paragraph 5 of the Sublease.

3.       DATA CENTER EXPANSION PREMISES TERM. The term for the Data Center
         Expansion Premises (as part of the Sublease Premises) shall commence on
         the Data Center Expansion Premises Commencement Date (as herein
         defined) and end on June 30, 2003 (subject to Sublessee's renewal
         rights set forth in Paragraph 5 of the Sublease). The Data Center
         Expansion Premises Commencement Date shall be the later of August 1,
         1999, or 30 days after the Data Center Expansion Premises are made
         available to Sublessee for Sublessee to commence its improvement work.
         Sublessee recognizes that the Data Center Expansion Premises are (a)
         being made available because Sublessor is relocating the users of such
         space into another building and that Sublessor anticipates that such
         relocation shall be accomplished and the Data Center Expansion Premises
         shall be available to Sublessee for Sublessee to commence its
         improvement work, by June 30, 1999; (b) that such relocation may be
         delayed if the space in the other building is not available, and (c)
         any such delay in the relocation and resulting availability of such
         space for use by Sublessee shall not eliminate or limit the obligations
         of Sublessee under the Sublease or this First Amendment, or create any
         claims against Sublessor, except to the extent the commencement date
         and corresponding rent obligations of Sublessee hereunder may be
         delayed. Notwithstanding anything to the contrary stated herein, if the
         Data Center Expansion Premises is not available to Sublessee for
         Sublessee to commence its improvement work by June 30,1999, then
         Sublessee may, at its option, and as its sole and exclusive remedy for
         such late availability, terminate the portion of this First Amendment
         relative to the Data Center Expansion Premises, by a notice to
         Sublessor indicating such termination, such notice to be delivered to
         Sublessor on or before July 15, 1999.

4.       BASE RENT FOR THE DATA CENTER EXPANSION PREMISES. The Base Rent for the
         Data Center Expansion Premises shall be equal to the Base Rent in the
         Sublease on a per rentable square foot basis as shown in Exhibit "B"
         attached hereto and incorporated herein by this reference. The Base
         Rent shown in Exhibit "B" includes the escalations required by
         Paragraph 1.b of the Sublease.

5.       TENANT IMPROVEMENT ALLOWANCE. Sublessor shall provide to Sublessee a
         Tenant Improvement Allowance equal to $0.05 per rentable square foot
         per month from the Data Center Rent Commencement Date to the end of the
         Term (i.e., June 30, 2003). By way of illustration only, assuming a
         Data Center Rent Commencement Date of August 1, 1999, the Tenant
         Improvement Allowance will be $14,875.00 (35 months times $0.05 per
         month per rentable square foot times 8,500 rentable square feet). Such
         Tenant Improvement Allowance will be payable to Sublessee by Sublessor


                                       2
<PAGE>   3
         within 15 days of the Data Center Expansion Premises being made
         available to Sublessee for Sublessee to commence its improvement work.

6.       TEMPORARY OFFICE SPACE. Sublessor agrees to sublease, "as-is, where
         is", the space indicated in Exhibit "A.1." for use as temporary office
         space (the "Temporary Office Space"). The commencement date for the
         term of the sublease of the Temporary Office Space on the 1st floor
         consisting of 15,000 rentable square feet shall be the later of
         December 15, 1998 or the date that Sublessee takes occupancy of the
         Temporary Office Space. On or before January 31, 1999, this First
         Amendment shall be reasonably modified to reflect the actual rentable
         square feet of the final design of the Temporary Office Space, such
         modification to be mutually determined by Sublessor and Sublessee.
         Usable square feet shall be measured according to the Standard Method
         for Measuring Area in Office Buildings, ANSI Z65.1-1996 (BOMA). The
         rental rate for the Temporary Office Space shall be $19.00 per rentable
         square foot which is a full service rate including operating expenses.
         Set forth in Exhibit B is a schedule of rent for the Temporary Office
         Space during the period from December 15, 1998 to December 14, 1999,
         subject to appropriate adjustment if the Commencement Date is other
         than December 15th. The term of the sublease of the Temporary Office
         Space shall end twelve (12) months from the date of commencement of
         same. Notwithstanding the foregoing, Sublessee shall have the option to
         extend the term of all or a portion of the Temporary Office Space (such
         portion as, in the sole opinion of the Sublessor, must not interfere
         with the use or sublease of the remainder of the Temporary Office Space
         and shall be no less than 2,000 rentable square feet) for an additional
         period of time terminating on the same date as the expiration of the
         Term of the Sublease (including any renewal thereof) upon the same
         terms and conditions set forth herein except the Base Rent therefore
         shall escalate by 3% per annum on each anniversary date, by delivering
         to Sublessor notice of its intent to do so provided such notice is
         delivered at least 90 days prior to the expiration of the term of the
         sublease of the Temporary Office Space.

7.       CONDITION OF SUBLEASE PREMISES. Sublessee shall take the Data Center
         Expansion Premises and the Temporary Office Space "as-is, where is",
         except that Sublessor has agreed to and shall provide, at no additional
         cost or expense to Sublessee, demising walls separating the Data Center
         Expansion Premises from other space on floor G2 and separating the
         Temporary Office Space from the other space on the 1st floor, in
         accordance with all applicable codes, but otherwise as Sublessor deems
         appropriate. In the case of the Data Center Expansion Premises, such
         demising wall shall be constructed during the time Sublessee is
         performing its construction in the Data Center Expansion Premises prior
         to the Data Center Expansion Premises Commencement Date, reasonably
         coordinated with Sublessee's construction so as not to interfere or
         cause a delay therewith. In the case of the Temporary Office Space,
         such demising wall(s) shall be constructed at such times as to minimize
         the disturbance of Sublessee's operations in the applicable areas.
         Sublessee has had the opportunity to and has inspected the Data Center
         Expansion Premises and the Temporary Office Space, and Sublessor makes
         and has made no representations or warranties whatsoever with respect
         to the Data Center Expansion Premises or Temporary Office Space or the
         fitness thereof for Sublessee's use. Notwithstanding anything to the
         contrary contained herein, all demising walls to be constructed by the


                                       3
<PAGE>   4
         Sublessor in the Data Center Expansion Premises and the Temporary
         Office Space shall be constructed in such locations as mutually agreed
         upon by the parties.

8.       PARKING ARRANGEMENTS. Paragraph 35 of the Sublease is deleted in its
         entirety and the following is substituted therefor: Sublessee shall be
         entitled to 2 parking passes per 1,000 rentable square feet of data
         center space and 4 parking passes per 1,000 rentable square feet of
         office space (including Temporary Office Space during the term of the
         Sublease for the Temporary Office Space) and Sublessee shall use no
         more than said amount of parking passes.

9.       LETTER OF CREDIT. The initial Letter of Credit amount of $99,999.00 as
         specified in Paragraph 7, subpart (a) of the Sublease will be replaced
         by a letter of credit of $140,000.00 with all other stipulations of
         Paragraph 7, subpart (a) of the Sublease remaining in effect. The
         reduced letter of credit referenced in Paragraph 7, subpart (b) of the
         Sublease is increased to $125,000. The reduced letter of credit
         referenced in Paragraph 7, subpart (c) of the Sublease is increased to
         $99,999.00.

10.      BROKERAGE COMMISSIONS. CB RICHARD ELLIS, INC. ("CBRE") HAS ACTED AS
         AGENT FOR SUBLESSOR IN THIS TRANSACTION. THE WESLEY COMPANY HAS ACTED
         AS AGENT FOR SUBLESSEE IN THIS TRANSACTION. CBRE AND THE WESLEY COMPANY
         SHALL EACH BE PAID A COMMISSION BY SUBLESSOR PURSUANT TO A SEPARATE
         AGREEMENT. Sublessor shall indemnify and hold Sublessee harmless, from
         and against all loss, cost, damage or expense, including, but not
         limited to, attorney's fees and court costs, incurred by Sublessee as
         result of Sublessor's breach of the foregoing covenant to pay CBRE and
         the Wesley Company their respective commissions due in connection with
         this transaction. Sublessor and Sublessee hereby indemnify one another,
         and hold one another harmless, from and against all loss, cost, damage
         or expense, including, but not limited to, attorney's fees and court
         costs, incurred by a party hereto as a result of any claims for
         brokerage fees or commissions due which are made by reason of such
         party having dealt with any broker (other than CBRE or THE WESLEY
         COMPANY). Sublessee shall cause any agent or broker representing
         Sublessee to execute a lien waiver to and for the benefit of Sublessor
         and Prime Landlord, upon receipt by such agent or broker of any
         commission due hereunder, waiving any and all lien rights with respect
         to the Building or Property such agent or broker has or might have
         under Georgia law.

11.      BINDING EFFECT. This First Amendment shall be governed by and construed
         in accordance with the laws of the State of Georgia, and shall be
         binding upon and inure to the benefit of the parties hereto and their
         respective heirs, successors, representatives and assigns, but always
         subject, in case of the Sublessee, to the limitations on assignment and
         sublease set forth in the Sublease. In the event of any inconsistency
         or conflict between the terms of this First Amendment and the Sublease,
         the terms hereof shall control. Time is of the essence of all terms of
         this First Amendment.

12.      CONTINUED VALIDITY. Except as hereinabove provided, all other terms and
         conditions of the Sublease shall remain unchanged and in full force and
         effect, and are hereby ratified and confirmed by Sublessor and
         Sublessee. Sublessee and Sublessor hereby


                                       4
<PAGE>   5
         each acknowledge and agree that, as of the date hereof, the Sublease is

         whatsoever and no Events of Default on the part of Sublessor or
         Sublessee have occurred under the Sublease.

13.      MODIFICATIONS. This First Amendment may not be changed, modified,
         discharged or terminated orally or in any manner other than by an
         agreement in writing signed by the Sublessor and Sublessee or their
         respective heirs, representatives, successors and permitted assigns.

14.      AUTHORITY. The person executing this First Amendment on behalf of
         Sublessee does hereby personally represent and warrant that Sublessee
         is a validly existing corporation and is fully authorized and qualified
         to do business in the State of Georgia, that the corporation has full
         right and authority to enter into this First Amendment, and the
         undersigned, who is signing on behalf of the corporation, is a duly
         authorized officer of the corporation and is authorized to sign on
         behalf of the corporation.

         IN WITNESS WHEREOF, the parties have set their hands and affixed their
seals to this First Amendment to be effective as of the day and year first above
written.

            Provisions) described as the Premises in Item 2 of the Basic Lease
            Provisions and that is more particularly described by the
            crosshatched area on Exhibit A attached hereto (hereinafter called
            (the "Premises"). The agreed rentable area of the Premises is hereby
            stipulated to be the "Agreed Rentable Area" of the Premises set
            forth in Item 2.b of the Basic Lease Provisions, irrespective of
            whether the same should be more or less as a result of minor
            variations resulting from construction of Tenant's Improvements (as
            defined in the Work Letter (herein so called) attached hereto as
            Exhibit C). The agreed rentable area of the Building is hereby
            stipulated to be the "Agreed Rentable Area" of the Building set
            forth in Item 1.b of the Basic Lease Provisions, irrespective of
            whether the same should be more or less as a result of minor
            variations resulting from actual construction or repair of the
            Building. Landlord also grants Tenant a non-exclusive license for
            the Term to use the Common Areas (as hereinafter defined) of the
            Building in common with others entitled to use the Common Areas,
            including, without limitation, Landlord, other tenants of the
            Building and their respective employees and invitees, and other
            persons authorized by Landlord, subject to the terms and conditions
            of this Lease and the rules and regulations applicable to the Common
            Areas.

1.102       Initial Term and Commencement. The initial term of this Lease shall
            be the period of time specified in Item 6 of the Basic Lease
            Provisions. The initial term shall commence on the Commencement Date
            (herein so called) set forth in Item 7 of the Basic Lease Provisions
            (as such Commencement Date may be adjusted pursuant to Sections 4
            and $ of the Work Letter) and, unless sooner terminated pursuant to
            the terms of this Lease, the initial term shall expire, without
            notice to Tenant, on the Expiration Date (herein so called) set
            forth in Item 8 of the Basic Lease Provisions (as such Expiration
            Date may be adjusted pursuant to Sections 4 and 5 of the Work
            Letter). As used in this Lease, "Term" shall mean the Initial Term
            and any validly exercised Renewal Term (as defined in Rider 1
            attached hereto).

SECTION 1.2 INSPECTION AND DELIVERY OF PREMISES, CONSTRUCTION OF LEASE SPACE
IMPROVEMENTS AND POSSESSION.

1.201       Delivery and Completion. Tenant hereby acknowledges that Tenant has
            inspected the Premises and the Common Areas (as hereinafter defined)
            and, except for latent defects discovered and reported to Landlord
            by Tenant within one hundred eighty (180) days from the Commencement
            Date, hereby (i) accepts the Common Areas in "as is" condition for
            all purposes, subject to Landlord's completion of its obligations
            under the Work Letter and (ii) subject to Landlord's completion of
            its obligations under the Work Letter, accepts the Premises
            (including the suitability of the Premises for the Permitted Use)
            for all purposes. Tenant will perform or cause to be performed the
            work and/or construction of Tenant's Improvements (as defined in the
            Work Letter) in accordance with the terms of the Work Letter and
            will use reasonable efforts to Substantially Complete (as defined in
            the Work Letter) Tenant's Improvements by the Commencement Date set
            forth in Item 7 of the Basic Lease Provisions. If Tenant's
            Improvements are not Substantially Complete by the Commencement Date
            set forth in Item 7 of the Basic Lease Provisions for any reason
            whatsoever (including, without limitation, because of any delays
            caused by Landlord), Tenant's sole remedy shall be an adjustment of
            the Commencement Date and the Expiration Date to the extent
            permitted under Sections 4 and 5 of the Work Letter.


                                       1

1.202       Acceptance of Premises Memorandum. Upon Substantial Completion (as
            defined in the Work Letter) of Tenant's Improvements, Landlord and
            Tenant shall execute the Acceptance of Premises Memorandum (herein
            so called) attached hereto as Exhibit D. If Tenant occupies the
            Premises without executing an Acceptance of Premises Memorandum,
            Tenant shall be deemed to have accepted the Premises for all
            purposes and Substantial Completion shall be deemed to have occurred
            on the earlier to occur of (i) actual occupancy or (ii) the
            Commencement Date set forth in Item 7 of the Basic Lease Provisions.

SECTION 1.3 REDELIVERY OF THE PREMISES. Upon the expiration or earlier
termination of this Lease or upon the exercise by Landlord of its right to
re-enter the Premises without terminating this Lease and subject to Tenant's
remaining obligations under this Section, Tenant shall immediately deliver to
Landlord the Premises, ordinary wear and tear excepted, but free of offensive
odors and in a safe, clean, neat, sanitary and operational condition, together
with all keys and parking and access cards. Tenant shall (i) within seven (7)
days after the expiration or earlier termination of this Lease, remove from the
Premises, at the sole expense of Tenant and unless Landlord is asserting its
lien rights therein, any equipment, machinery, trade fixtures and personalty
installed or placed in the Premises by or on behalf of Tenant and (ii) if
requested by Landlord for improvements designated at the time Landlord grants
consent to the construction or installation of the Tenant Improvements, (a)
remove all or any part of said improvements made to and conduit installed in the
Premises or the Building by or on behalf of Tenant and (b) restore the Premises
to the condition existing prior to the installation of such improvements. All
removals and work described above shall be accomplished in a good and
workmanlike manner and shall be conducted in a fashion so as not to damage the
Premises or the Building or any portion thereof. Tenant shall, at its expense,
promptly repair any damage caused by any such removal or work. If Tenant fails
to deliver the Premises in the condition aforesaid, then Landlord may restore
the Premises to such a condition at Tenant's expense. All property required to
be removed pursuant to this Section not removed within the time period required
hereunder shall thereupon be conclusively presumed to have been abandoned by
Tenant and Landlord may, at its option, take over possession of such property
and either (a) declare the same to be the property of Landlord by written notice
to Tenant at the address provided herein or (b) at the sole cost and expense of
Tenant, remove and store and/or dispose of the same or any pan thereof in any
manner that Landlord shall choose without incurring liability to Tenant or any
other person.

SECTION 1.4 HOLDING OVER. In the event Tenant or any party under Tenant claiming
rights to this Lease, retains possession of the Premises after the expiration or
earlier termination of this Lease, such possession shall constitute and be
construed as a tenancy at will only, subject, however, to all of the terms,
provisions, covenants and agreements on the pan of Tenant hereunder; such
parties shall be subject to immediate eviction and removal and Tenant or any
such party shall pay Landlord as rent for the period of such holdover an amount
equal to the greater of (i) one and one-half (1.5) times the Basic Annual Rent
and Additional Rent (as hereinafter defined) in effect immediately preceding
expiration or termination, as applicable, prorated on a daily basis or (ii) the
then prevailing market rental rate, prorated on a daily basis. Landlord and
Tenant agree that they have included the foregoing provision for liquidated
damages because the actual damages to be incurred by Landlord can reasonably be
expected to approximate the amount of liquidated damages called for herein and
because the actual amount of such damages would be difficult if not impossible
to measure accurately. Tenant shall also pay and agrees to indemnify and hold
Landlord harmless from any and all damages sustained by Landlord as a result of
such holdover. The rent during such holdover period shall be payable to Landlord
in accordance with the provisions of Article 2. Tenant will vacate the Premises
and deliver same to Landlord within fourteen (14) days after Landlord's delivery
of written notice to Tenant to vacate the Premises. No holding over by Tenant,
whether with or without consent of Landlord, shall operate to extend the term of
this Lease; no payments of money by Tenant to Landlord after the expiration or
earlier termination of this Lease shall reinstate, continue or extend the term
of this Lease; and no extension of this Lease after the expiration or earlier
termination thereof shall be valid unless and until the same shall be reduced to
writing and signed by both Landlord and Tenant.

                  improvement made to the Property by Landlord that is required
                  under any governmental law or regulation which is not in
                  effect, or is in effect but is not interpreted to affect the
                  Building, on the date this Lease is executed, amortized over
                  its useful life, together with an amount equal to interest at
                  the rate often percent (10%) per annum (the "Amortization

                  Operating Expenses), amortized over such period as is

                  equal to interest at the Amortization Rate on the unamortized

            (e)   Adjustments on Account of Submetered Electricity. So long as

                  applicable year, and the cost of submetered electricity
                  provided to other tenants of the Building during the
                  applicable year; Tenant's pro rata share of Operating Expenses
                  shall include the electrical expenses attributable to areas of
                  the Building other than tenant occupied or occupiable areas
                  multiplied by a fraction, the numerator of which is the Agreed
                  Rentable Area of the Premises and denominator of which is the
                  Agreed Rentable Area of the Building.

2.202       Gross-Up. Operating Expenses shall be grossed up to include all
            additional costs and expenses of owning, operating, maintaining and
            managing the Building which Landlord reasonably determines that it
            would have incurred, paid or been obligated to pay during such year
            if the Building had been one hundred percent (100%) occupied.

2.203       Payment Obligation. In addition to the Basic Rent specified in this
            Lease, Tenant shall pay to Landlord the Additional Rent, in each
            calendar year or partial calendar year during the term of this
            Lease, payable in monthly installments as hereinafter provided. At
            least thirty (30) days prior to each calendar year commencing after
            the Commencement Date (or as soon thereafter as is reasonably
            possible), Landlord shall give Tenant written notice of Tenant's
            estimated Additional Rent (other than Monthly Submetered Electrical
            Charges, Monthly Submetered BTU Charges and the charge for after
            hours HVAC, each of which will be payable monthly in arrears within
            thirty (30) days after receipt of an invoice therefor) for the
            applicable calendar year and the amount of the monthly installment
            due for each month during such year. Tenant shall pay to Landlord on
            the first day of each month beginning the first calendar year
            occurring after the Commencement Date the amount of the applicable
            monthly installment; provided, however, if the applicable


                                       4
<PAGE>   14

            installment covers a partial month, then such installment shall be
            prorated on a daily basis. Within one hundred twenty (120) days
            after the end of (i) each calendar year and (ii) the Expiration Date
            or as soon thereafter as is reasonably possible, Landlord shall
            prepare and deliver to Tenant a statement showing Tenant's actual
            Additional Rent for the applicable calendar year, provided that with
            respect to the calendar year in which the Expiration Date occurs,
            (x) that calendar year shall be deemed to have commenced on January
            1 of that year and ended on the Expiration Date (the "Final Calendar
            Year") and (y) Landlord shall have the right to estimate the actual
            Operating Expenses allocable to the Final Calendar Year but which
            are not determinable within such 120 day period. If Tenant's total
            monthly payments of Additional Rent for the applicable year are less
            than Tenant's actual Additional Rent, then Tenant shall pay to
            Landlord the amount of such underpayment. If Tenant's total monthly
            payments of Additional Rent for the applicable year are more than
            Tenant's actual Additional Rent, then Landlord shall credit against
            the next Additional Rent payment or payments due from Tenant the
            amount of such overpayment; provided, however, with respect to the
            Final Calendar Year, Landlord shall pay to Tenant the amount of such
            excess payments, less any amounts then owed to Landlord. Unless
            Tenant takes written exception to any item within ninety (90) days
            after the furnishing of an annual statement, such statement shall be
            considered as final and accepted by Tenant. Any amount due Landlord
            as shown on any such statement shall be paid by Tenant within thirty
            (30) days after it is furnished to Tenant.

2.204       Revisions in Estimated Additional Rent. If Real Estate Taxes,
            utility expenses or Additional Pass Through Costs increase during a
            calendar year (based on new information and supporting documentation
            from actual or anticipated operations of the Building) or if the
            number of square feet of rentable area in the Premises increases,
            Landlord may revise the estimated Additional Rent during such year
            by giving Tenant written notice to that effect and thereafter Tenant
            shall pay to Landlord, in each of the remaining months of such year,
            an additional amount equal to the amount of such increase in the
            estimated Additional Rent divided by the number of months remaining
            in such year.

SECTION 2.3 RENT DEFINED AND NO OFFSETS. Basic Annual Rent, Additional Rent and
all other sums (whether or not expressly designated as rent) required to be paid
to Landlord by Tenant under this Lease (including, without limitation, any sums

forth in Sections 5.202, 7.1 and 8.3.

SECTION 2.4 LATE CHARGES. If any installment of Basic Annual Rent or Additional

                                SECURITY DEPOSIT

Tenant will provide to Landlord on the date this Lease is executed by Tenant the
Security Deposit set forth in Item 9 of the Basic Lease Provisions as security
for the performance of the terms hereof by Tenant. The Security Deposit may be
in the form of an unconditional and irrevocable letter of credit with a term of
no less than one year and on a form satisfactory to Landlord, which shall be
renewed or shall provide for adjustment in a manner reasonably satisfactory to
Landlord each year in accordance with the following schedule:

            End of first Lease year - renew in same amount

            End of second Lease year - renew in 2/3 of original amount

            End of third Lease year - renew in 1/2 of original amount

No Security Deposit shall be required after the fourth anniversary of the
Commencement Date. Tenant shall, at the proper times prior to the fourth
anniversary of the Commencement Date, provide an additional Security Deposit
with Landlord on the same prorata percentages and for the same time frames with
respect to any future finish allowance given to Tenant in connection with an
expansion or other addition to the Premises. Tenant shall not be entitled to
interest thereon and Landlord may commingle such Security Deposit with any other
funds of Landlord. The Security Deposit shall not be considered an advance
payment of rental or a measure of Landlord's damages in case of default by
Tenant. If Tenant defaults with respect to any provision of this Lease, Landlord
may, but shall not be required to, from time to time, without prejudice to any
other remedy, draw on any letter of credit and use, apply or retain all or any
part of this Security Deposit for the payment of any Rent or any other sum in
default or for the payment of any other amount which Landlord may spend or
become obligated to spend by reason of Tenant's default or to compensate
Landlord for any other loss or damage which Landlord may suffer by reason of
Tenant's default, including, without limitation, costs and attorneys' fees
incurred by Landlord to recover possession of the Premises. If Tenant is not in
default of the Lease on the fourth anniversary of the Commencement Date, the
Security Deposit shall be reduced to $0.00 and any letter of credit shall
promptly be returned to Tenant. Tenant agrees that it will not assign or
encumber or attempt to assign or encumber the monies deposited herein as the
Security Deposit and that Landlord and its successors and assigns shall not be
bound by any such actual or attempted assignment or encumbrance. Regardless of
any assignment of this Lease by Tenant, Landlord may return the Security Deposit
to the original Tenant, in the absence of evidence satisfactory to Landlord of
an assignment of the right to receive the Security Deposit or any part of the
balance thereof.

                                OCCUPANCY AND USE

SECTION 4.1 USE OF PREMISES.

4.101       General. The Premises shall, subject to the remaining provisions of
            this Section, be used solely for the Permitted Use (herein so
            called) specified in Item II of the Basic Lease Provisions. Without
            in any way limiting the foregoing, Tenant will not use, occupy or
            permit the use or occupancy of the Premises for any purpose (and the
            Permitted Use shall not include any use) which is forbidden by or in
            violation of any law, ordinance or governmental or municipal
            regulation, order, or certificate of occupancy, or which may be
            dangerous to life, limb or property; or permit the maintenance of
            any public or private nuisance; or do or permit any other thing
            which may disturb the quiet enjoyment of any other tenant of the
            Property; or keep any substance or carry on or permit any operation
            which might emit offensive odors or conditions from the Premises; or
            commit or suffer or permit any waste in or upon the Premises; or
            sell, or permit the sale in any form by or to any of Tenant's agents
            or employees or other parties in the Premises except through vending
            machines in employee lunch or rest areas within the Premises for use
            by Tenant's employees only; or use any apparatus which makes undue
            noise or vibrations in the Building; or permit anything to be done
            which would increase the fire and extended coverage insurance rate
            on the Building or Building contents and, if there is any increase
            in such rate by reason of acts of Tenant, then Tenant agrees to pay
            such increase upon demand therefor by Landlord; or use, occupy or
            permit the use or occupancy of the Premises as offices or agencies
            of a foreign government or political subdivision, offices of any
            governmental bureau or agency of the United States or any state or
            political subdivision thereof, or offices of personnel agencies.
            Payment by Tenant of any such rate increase shall not be a waiver of
            Tenant's duty to comply herewith. Tenant shall keep the Premises
            neat and clean at all times. Tenant shall promptly correct any
            violation of a governmental law, rule or regulation relating to the
            Premises. Tenant shall comply with any direction of any governmental
            authority having jurisdiction which imposes any duty upon Tenant or
            Landlord with respect to the Premises or with respect to the
            occupancy or use thereof.

                  or toxic substances, materials, wastes or chemicals under
                  then-current applicable governmental laws, rules or
                  regulations.

            (b)   Tenant shall not knowingly incorporate into, or use or
                  otherwise place or dispose of at, the Premises, the Building
                  or on the Land any Hazardous Materials, except for use and
                  storage of cleaning and office supplies used in the ordinary
                  course of Tenant's business and then only if (i) such
                  materials are in small quantities, properly labeled and
                  contained, (ii) such materials are handled and disposed of in
                  accordance with the highest accepted industry standards for
                  safety, storage, use and disposal, (iii) notice of and a copy
                  of the current material safety data sheet is provided to
                  Landlord for each such hazardous or toxic material and (iv)
                  such materials are used, transported, stored, handled and
                  disposed of in accordance with all applicable governmental
                  laws, rules and regulations. Landlord shall have the right to
                  periodically inspect, take samples for testing and otherwise
                  investigate the Premises for the presence of Hazardous
                  Materials.

            (c)   Landlord shall not knowingly dispose of at the Premises,
                  Building or the Land any Hazardous Materials and shall
                  otherwise deal with all Hazardous Materials at the Premises,
                  Building or Land of which Landlord is aware in a manner that
                  will not materially and adversely affect Tenant's access, use
                  or occupancy of the Premises.

            (d)   If Landlord or Tenant ever has knowledge of the presence in
                  the Premises or the Building or the Land of Hazardous
                  Materials which affect the Premises, the party having
                  knowledge shall notify the other party thereof in writing
                  promptly after obtaining such knowledge.

            (e)   If Tenant or its employees, agents or contractors shall ever
                  violate the provisions of paragraph (a) of this subsection
                  4.102 or otherwise contaminate the Premises or the Property,
                  then Tenant shall clean up, remove and dispose of the material
                  causing the violation, in compliance with all applicable
                  governmental standards, laws, rules and regulations and then
                  prevalent industry practice and standards and shall repair any
                  damage to the Premises or Building within such period of time
                  as may be reasonable under the circumstances after written
                  notice by Landlord (collectively, "Tenant's Environmental
                  Corrective Work"). Tenant shall notify Landlord of its method,
                  time and procedure for any clean up or removal and Landlord
                  shall have the right to require reasonable changes in such
                  method, time or procedure or to require the same to be done
                  after normal business hours. Tenant's obligations under this
                  subsection 4.102(e) shall survive the termination or
                  expiration of this Lease.

            (f)   If any Tenant's Environmental Corrective Work (i) is to occur
                  outside of the Premises or (ii) will in any way affect any
                  portion of the Building other than the Premises, then Landlord
                  shall have the right to undertake Tenant's Environmental
                  Corrective Work. Tenant shall allow Landlord, its agents,
                  employees and contractors such access to the Premises as
                  Landlord may reasonably request in order to perform such
                  Tenant's Environmental Corrective Work.

            (g)   To the actual knowledge of Landlord, (i) no Hazardous
                  Materials are present on the Property or the soil, surface
                  water or groundwater thereof in amounts exceeding applicable
                  law, (ii) no underground storage tanks are present on the
                  Property in violation of applicable law, and (iii) no action,

            as interpreted and enforced, for each of the following: (i)
            alterations or improvements to any portion of the Premises
            (including the initial build-out of the Premises); (ii) obligations
            or complaints resulting in obligations, arising under or out of
            Title I of the Americans With Disabilities Act or Tenant's
            employer-employee obligations; (iii) obligations, or complaints
            resulting in obligations, arising under or out of the conduct or
            operations of Tenant's business, including any obligations or
            requirements for barrier removal to customers or invitees as a
            commercial facility or as a public accommodation (as defined in the
            Disability Acts); and (iv) any change in the nature of Tenant's
            business, or its employees, or financial net worth, or Tenant's

            should be expanded to include a full floor, Landlord (and not
            Tenant) shall be responsible for compliance with the Disabilities
            Acts with respect to all Common Areas within the Premises, provided
            that Landlord's responsibilities shall not exceed those applicable
            to Landlord if the Premises were on a multi-tenant floor and shall
            not increase by virtue of Tenant's specific use of the Premises.

SECTION 4.2 PERMITS. Tenant shall obtain the certificate of occupancy, if any,
required for occupancy of the Premises following construction of Tenant's
Improvements. If any governmental license or permit shall be required for the
proper and lawful conduct of Tenant's business in the Premises or any part
thereof, Tenant, at its expense, shall procure and thereafter maintain such
license or permit. Additionally, if Tenant's Improvements or any subsequent
alteration or improvement made to the Premises by Tenant or Tenant's use of the
Premises require any modification or amendment of any certificate of occupancy
for the Building or the issuance of any other permit of any nature whatsoever,
Tenant shall, at its expense, take all actions to procure any such modification
or amendment or additional permit.

SECTION 4.3 COMPLIANCE WITH LAWS. Tenant shall comply with all laws, statutes,
ordinances, orders and regulations affecting (i) Tenant's use and occupancy of
the Premises, (ii) any improvements constructed within the Building by or on
behalf of Tenant and (iii) any equipment installed within the Building by Tenant

regulations (the "Rules and Regulations") generally applying to tenants in the
Building as may be reasonably adopted from time to time by Landlord for the
management, safety, care and cleanliness of, and the preservation of good order
and protection of property in, the Premises and the Building and at the
Property. All such Rules and Regulations are hereby made a part hereof.
Notwithstanding anything contained herein to the contrary, Tenant shall not be
required to comply with any new or amended rules and regulations, if the same
are designed to have a discriminatory effect on Tenant or unreasonably and
materially interfere with Tenant's permitted use of the Premises. The Rules and
Regulations in effect on the date hereof are on file with the Property Manager
and are attached hereto as Rider 4. All changes and amendments to the Rules and
Regulations sent by Landlord to Tenant in writing and conforming to the
foregoing standards shall be carried out and observed by Tenant. Landlord hereby
reserves all rights necessary to implement and enforce the Rules and Regulations
and each and every provision of this Lease.

SECTION 4.5 ACCESS. Without being deemed guilty of an eviction of Tenant and
without abatement of Rent, Landlord or its authorized agents shall have the
right to enter the Premises, upon reasonable notice, to inspect the Premises, to
show the Premises to prospective lenders, purchasers or tenants and to fulfill
Landlord's obligations or exercise its rights under this Lease. Tenant hereby
waives any claim for damages for any injury or inconvenience to or interference
with Tenant's business, any loss of occupancy or quiet enjoyment of the Premises
and any other loss occasioned by Landlord's reasonable exercise of its rights
under this Section 4.5. For each of the aforesaid purposes, Landlord shall at
all times have and retain a key with which to unlock the doors to and within the
Premises, excluding Tenant's vaults and safes. Landlord shall have the right to
enter the Premises in

when entering the secured area (shown as the cross-hatched area on Exhibit A-1).
Any such entry by Landlord and Landlord's agents shall comply with all
reasonable security measures of Tenant, and shall be made so as not to
unreasonably interfere with the conduct of Tenant's business.

                  serving the Building, at such temperatures and in such amounts
                  as is customary in buildings of comparable size, quality and
                  in the general vicinity of the Building, with such adjustments
                  as Landlord reasonably deems necessary for the comfortable
                  occupancy of the Premises, subject to events of force majeure
                  and to any governmental requirements, ordinances, rules,
                  regulations, guidelines or standards relating to, among other
                  things, energy conservation. Landlord shall, on a continuous
                  basis and at all times, supply the Premises with chilled water
                  from the Building's HVAC system to meet the following
                  performance standards: chilled water meeting the load
                  requirements of one (1) ton per 200 square feet of Agreed
                  Rentable Area leased by Tenant delivered at a specified
                  constant temperature (+/-5(0) F.) selected from temperatures
                  in a range from 42 - 48 F. The specific temperature may be
                  changed by Landlord from time to time within the range

                  requested by Tenant within the time periods specified by
                  Landlord, and provided Tenant pays, as Additional Rent,
                  Landlord's then current actual cost to provide after hours
                  HVAC. The current actual cost is $25.00 per hour.

            (c)   Submetering of Air Conditioning. Tenant, as part of Tenant's
                  Improvements, shall install, maintain and repair at Tenant's
                  expense separate metering for all of Tenant's mainframe
                  computer heat exchangers, Tenant's HVAC air handling units,
                  and Tenant's fan coil units in the Computing Center (such
                  mainframe computer heat exchangers, HVAC air handling units,
                  and fan coil units are called the "HVAC Equipment" and such


                                       9
<PAGE>   19

                  meters are called "BTU Meters"). The BTU Meters measure the
                  energy consumed by the HVAC Equipment by British Thermal Units
                  ("BTUs"). As part of Additional Rent, Tenant will pay
                  Landlord, monthly, the cost of the energy consumed by the HVAC
                  Equipment ("Monthly Submetered BTU Charges"), which cost shall
                  be the product of (x) the BTUs consumed during such month by
                  the HVAC Equipment (as evidenced by the BTU Meters),
                  multiplied by (y) the per hour amount then charged to tenants
                  in the Building generally, but not to exceed Landlord's then
                  current actual cost, which rate is currently $8.56 per
                  1,000,000 BTUs per hour.

5.103       Electricity.

            (a)   Consumption. Landlord shall furnish to the Premises electric
                  current for normal office purposes at the electrical panel on
                  the Building Floor on which the Premises are located;
                  provided, however, Tenant shall be solely responsible for the
                  costs of electrical consumption (without duplication) within
                  the Premises which is in excess of 7.0 watts per square foot
                  of the Agreed Net Rentable Area of the Premises (such
                  consumption is herein referred to as "Excess Consumption" and
                  the costs of Excess Consumption are herein referred to as
                  "Excess Consumption Costs"). Without in any way limiting
                  Tenant's responsibility for Excess Consumption Costs, Tenant
                  shall not (i) without the express prior written consent of
                  Landlord (except as provided below), install or use or permit
                  the installation or use of any computer or electronic data
                  processing equipment or any other electrical equipment which
                  (singly) requires a voltage other than 120 volts single phase
                  or otherwise has high electrical consumption or (ii) use
                  electric current in excess of the capacity of the feeders or
                  lines to the Building or the risers or wiring installation of
                  the Building or the Premises.

            (b)   Submetering Electrical Usage. All electricity delivered to the
                  Premises shall be submetered, and in that regard Tenant shall,
                  at Tenant's expense and as part of Tenant's Improvements,
                  install or cause to be installed, maintain and repair
                  submeters. All electrical lines to or panel boxes for the
                  Premises that are submetered are herein referred to as
                  "Submetered Lines," and each such submeter which measures
                  electrical consumption of the Submetered Lines or the Premises
                  is herein referred to as a "Submeter." As a part of Additional
                  Rent, Tenant shall pay Landlord the Excess Consumption Costs,
                  which shall be equal to the kilowatt hours of Excess
                  Consumption multiplied by the then current cost per kilowatt
                  hour of electricity charged by the electric utility provider
                  to the Building. Billing for metered electricity will be on an
                  actual cost basis from the electric utility without mark-up to
                  Landlord.

            (c)   UPS. Landlord shall also furnish, twenty-four (24) hours a
                  day, seven (7) days a week, to the Premises uninterruptible
                  power supply ("UPS") power with the characteristics described
                  below to meet Tenant's loads in an amount not to exceed 50
                  kVA. Tenant shall have the right to install, at its sole cost
                  and expense and with Landlord's prior written approval,
                  equipment of high electrical consumption (480 volts) which may
                  be connected to the UPS source on Tenant's floor. Tenant may
                  install, at its sole cost and expense and with Landlord's
                  prior written approval, circuits within the Premises to
                  connect to the UPS. All requirements for UPS will be
                  separately metered and billed to the Tenant as additional
                  rent. The Building shall also provide for Tenant's use an
                  alternate electrical power supply to the Premises from standby
                  generators located in the Building ("Building Backup
                  Generators"). Such alternate supply shall be used only in case
                  the Building's normal power supply is interrupted or during
                  temporary, scheduled testing of such equipment, or as deemed
                  necessary by Landlord. Such power supply shall be sufficient
                  to supply, under normal operating conditions, electrical power
                  adequate for the operation of the Building, subject to the
                  limitations described herein, and the Premises. For purposes
                  of this 5.103(c), the total power requirements for all
                  equipment in the Premises,


                                       10

                  whether non-emergency or emergency, shall not exceed 111 kVA.
                  In the event Tenant desires to exceed the 111 kVA limit,
                  Tenant must obtain the written approval of Landlord and, if
                  approved (and subject to availability), Tenant shall pay a
                  one-time charge of Landlord's cost to provide such additional
                  power, which cost is currently $750 per kVA. The Building
                  Back-up Generators shall be maintained so as to start up and
                  operate automatically in the event of interruption of normal
                  power supply, and shall provide emergency power to all
                  Building systems on a priority basis. As generator capacity
                  becomes available, the system begins loading the critical load
                  groups in order of priority. The system will not add load
                  unless generator capacity is available. Those Building systems
                  receiving priority in order of their importance are fire and
                  life safety systems, elevator systems, chilled water and
                  building automation systems, UPS power and data center floors
                  of the Building. Tenant acknowledges that in the event of an
                  emergency, the Building Back-up Generators may be required to
                  shed non-critical loads servicing standard Building systems
                  lighting to office space and Common Areas, power to the
                  cafeteria, components of the transportation systems and other
                  Building systems not critical to the continued operation of
                  the data center floors.

5.104       Water. Landlord shall furnish regular (not deionized) water for
            humidification, drinking, cleaning and lavatory purposes only in the
            Premises and to appropriate places in the Common Areas.

5.105       Janitorial Services. Landlord shall provide janitorial services to
            the Premises after 6:00 p.m. in accordance with the standards set
            forth on Exhibit H attached hereto and made a part hereof, provided 
            Tenant complies with subsection 6.201 below.

5.106       Common Areas. Landlord shall perform routine maintenance in the
            Common Areas (hereinafter defined).

5.107       Bulbs and Ballasts. Landlord shall provide Building standard bulbs
            and ballasts as necessary in the Premises. Landlord shall also
            provide non-building standard bulbs and ballasts provided Tenant
            shall pay the cost thereof, together with an administrative fee
            equal to ten percent (10%) of such cost.

5.108       Fire Suppression. Landlord shall provide Tenant access to the
            existing Building fire alarm system to accommodate a separate
            pre-action fire suppression system to be installed by Tenant at its
            sole cost and expense within the Premises. The Tenant fire
            suppression system shall be compatible with the Building fire alarm
            system and shall otherwise be acceptable to Landlord in its sole
            discretion. Tenant shall provide to Landlord written plans and
            specifications for the Tenant fire suppression system. All wiring
            and other improvements necessary for the system outside of the
            Building fire alarm closet, including (without limitation) control
            wires for indication of system alarm, system trouble, system tamper,
            and flow condition, shall be installed and paid for by Tenant.

5.109       Security. Landlord shall provide security personnel, equipment, and
            access control in accordance with the practice generally of other
            Class A high-rise office buildings in the Central Business District
            of Houston, Texas. Tenant acknowledges that, currently, Landlord
            maintains security personnel on site twenty-four (24) hours per day,
            seven (7) days per week and a security officer at the main lobby
            security desk from 8 a.m. to 7 p.m., with the building security
            control center manned twenty-four (24) hours per day. Landlord shall
            permit Tenant, at Tenant's sole cost and expense, to utilize the
            Building's security control systems to limit access to the Premises
            upon terms and conditions currently followed by other tenants of the
            Building using such system. Landlord shall provide Tenant, at no
            expense to Tenant, one hundred (100) security cards for purposes of
            permitting Tenant and its employees to access the Building security
            system.

SECTION 5.2 SERVICE INTERRUPTION.

5.201       Service Interruption. Landlord shall not be liable for and, except
            as provided in subsection 5.202 below, Tenant shall not be entitled
            to any abatement or reduction of Rent by reason of, Landlord's
            failure to maintain temperature or electrical constancy levels or to
            furnish any of the foregoing services when such failure is caused by
            accident, breakage, repairs, strikes, lockouts or other labor
            disturbance or labor dispute of any character, governmental
            regulation, moratorium or other governmental action, inability by
            exercise of reasonable diligence to obtain electricity, water or
            fuel, or by any other cause beyond Landlord's reasonable control
            (collectively, "Uncontrollable Events"), nor shall any such
            Uncontrollable Event or results or effects thereof be construed as
            an eviction (constructive or actual) of Tenant or as a breach of any
            implied warranty, or relieve Tenant front the obligation to perform
            any covenant or agreement herein and in no event shall Landlord be
            liable for damage to persons or property (including, without
            limitation, business interruption), or be in default hereunder, as a
            result of any such Uncontrollable Event or results or effects
            thereof. However, promptly upon any interruption, curtailment,
            stoppage or suspension of services and/or utilities to be furnished
            by Landlord under Section 5.1, Landlord will commence diligent good
            faith efforts to restore same and will diligently proceed with such
            efforts until such services and/or utilities are restored.

5.202       Limited Right to Abatement of Rent. If any portion of the Premises
            becomes unfit for occupancy because Landlord fails to deliver any
            service as required under Section 5.1 above for any period (other
            than a reconstruction period conducted pursuant to Section 7.1 or
            Article 8 below) exceeding five (5) consecutive days after written
            notice by Tenant to Landlord and provided such failure is not caused
            by Tenant, Tenant's contractors or any of their respective agents or
            employees, Tenant shall be entitled to a fair partial abatement of
            Basic Annual Rent and Additional Rent for any such portion of the
            Premises from the expiration of such five (5) consecutive day period
            until such service is restored. If the failure to furnish services
            which causes the Premises to be unfit for occupancy is caused by the
            failure of Landlord, its employees, agents or contractors, to
            perform Landlord's duties under this Lease and is not cured within
            thirty (30) consecutive days after receipt of Tenant's notice to
            Landlord, or if the failure to furnish services which causes the
            Premises to be unfit for occupancy is not caused by such failure and
            is not cured within ninety (90) consecutive days after receipt of
            Tenant's notice to Landlord, then Tenant at its option may terminate
            this Lease and all of its obligations for the remaining balance of
            the Term by delivering notice to Landlord within ten (10) days after
            the applicable thirty (30) consecutive day period or ninety (90)
            consecutive day period, as the case may be. For purposes of this
            Section 5.202, the term "unfit for occupancy" shall mean the
            Premises cannot reasonably be used for its then current Permitted
            Use.

                                    ARTICLE 6
               MAINTENANCE, REPAIRS, ALTERATIONS AND IMPROVEMENTS

SECTION 6.1 LANDLORD'S OBLIGATION TO MAINTAIN AND REPAIR. Landlord shall
(subject to Section 7.1, Section 7.4, Article 8 below and Landlord's rights
under Section 2.2 above and except for ordinary wear and tear) maintain exterior
walls, roof and load bearing elements and Common Areas of the Building. Except
for load bearing elements of the Building located within the Premises, Landlord
shall not be required to maintain or repair any portion of the Premises.

SECTION 6.2 TENANT'S OBLIGATION TO MAINTAIN AND REPAIR.

6.201       Tenant's Obligation. Tenant shall, at Tenant's sole cost and
            expense, (i) maintain and keep the interior of the Premises
            (including, but not limited to, all fixtures, walls, ceilings,
            floors, doors, windows [except replacement of exterior plate glass
            unless the replacement is by reason of damage caused by Tenant],
            appliances and equipment which are a part of the Premises) in good
            repair and condition, (ii) repair or replace any damage or injury
            done to the Building or any other part of the


                                       12
<PAGE>   22

            property caused by Tenant, Tenant's agents, employees, licensees,
            invitees or visitors or resulting from a breach of its obligations
            under this Section 6.2 and (iii) indemnify and hold Landlord
            harmless from, and reimburse Landlord for and with respect to, any
            and all costs, expenses (including reasonable attorneys' fees),
            claims and causes of action arising from or incurred by and/or
            asserted in connection with such maintenance, repairs, replacements,
            damage or injury. All repairs and replacements performed by or on
            behalf of Tenant shall be performed in a good and workmanlike manner
            and in accordance with the standards applicable to alterations or
            improvements performed by Tenant. Tenant shall continue to pay Rent,
            without abatement, during any period that repairs or replacements
            are performed or required to be performed by Tenant under this
            Section 6.2.

6.202       Rights of Landlord. Landlord shall have the same rights with respect
            to repairs performed by Tenant as Landlord has with respect to
            improvements and alterations performed by Tenant under subsection
            9.303 below. In the event Tenant fails, in the reasonable judgment
            of Landlord, to maintain the Premises in good order, condition and
            repair, or otherwise satisfy its repair and replacement obligations
            under subsection 6.201 above, Landlord shall have the right to
            perform such maintenance, repairs and replacements at Tenant's
            expense. Tenant shall pay to Landlord on demand any such cost or
            expense incurred by Landlord, together with interest thereon at the
            rate specified in Section 15.10 below from the date of demand until
            paid.

SECTION 6.3 IMPROVEMENTS AND ALTERATIONS.

6.301       Landlord's Construction Obligation. Landlord's sole construction
            obligation under this Lease is as set forth in the Work Letter.

6.302       Alteration of Building. Subject to Section 4.5, Landlord hereby
            reserves the right and at all times shall have the right to repair,
            change, redecorate, alter, improve, modify, renovate, enclose or
            make additions to any, part of the Property (including, without
            limitation, structural elements and load bearing elements within the
            Premises) and to enclose and/or change the arrangement and/or
            location of driveways or parking areas or landscaping or other
            Common Areas of the Property, all without being held guilty of an
            actual or constructive eviction of Tenant or breach of any implied
            warranty and without an abatement of Rent (the "Reserved Right").
            Without in any way limiting the generality of the foregoing,
            Landlord's Reserved Right shall include, but not be limited to, the
            right to do any of the following: (i) erect and construct
            scaffolding, pipe, conduit and other structures on, within and
            outside of the Premises when reasonably required by the nature of
            the changes, alterations, improvements, modifications, renovations
            and/or additions being performed, (ii) repair, change, renovate,
            remodel, alter, improve, modify or make additions to the
            arrangement, appearance, location and/or size of entrances or
            passageways, doors and doorways, corridors, elevators, elevator
            lobbies, stairs, toilets or other Common Areas or Service Areas,
            (iii) temporarily close any Common Area and/or temporarily suspend
            Building services and facilities in connection with any repairs,
            changes, alterations, modifications, renovations or additions to any
            part of the Building, (iv) repair, change, alter or improve
            plumbing, pipes and conduits located in the Building, including
            without limitation, those located within the Premises, the Common
            Areas, the Service Corridors or the Service Areas (hereinafter
            defined) of the Building and (v) repair, change, modify, alter,
            improve, renovate or make additions to the Building's central
            heating, ventilation, air conditioning, electrical, mechanical or
            plumbing systems. When exercising the Reserved Right, Landlord will
            interfere with Tenant's use and occupancy of the Premises as little
            as is reasonably practicable. Landlord shall schedule all repairs
            and alterations, except emergencies, with twenty-four (24) hours
            notice to Tenant and shall, to the extent possible, conduct the same
            before or after normal business hours so as to minimize disruption
            of Tenant's business operations. Absent an emergency, Landlord shall
            not enter the secure area identified in Exhibit A-I unless
            accompanied by a representative of Tenant. Landlord shall be
            relieved of all obligations to provide services to the secured area
            chat require Landlord's access to the secured area, such as
            janitorial service. If Landlord enters such secure area during an
            emergency,


                                       13
<PAGE>   23

            Landlord shall use reasonable efforts to notify Tenant of such entry
            immediately thereafter. For purposes of this Lease, an emergency
            shall be deemed to exist if Landlord reasonably believes that a
            condition within the Premises presents an imminent danger of injury
            or loss of life or damage to property.

6.303       Alterations, Additions, Improvements and Installations by Tenant.
            Tenant shall not, without the prior written consent of Landlord,
            make any changes, modifications, alterations, additions or
            improvements (other than Tenant's Improvements under the Work
            Letter) to, or install any equipment or machinery (other than office
            equipment and unattached personal property) on, the Premises (all
            such changes, modifications, alterations, additions, improvements
            (other than Tenant's Improvements under the Work Letter] and
            installations are herein collectively referred to as
            "Installations") if any such Installations would (i) affect any
            structural element of the Property, (ii) reduce the load bearing
            capacity of any portion of the Building or the Garage (other than by
            reason of the weight of the Installations themselves, as long as
            total load capacity is not exceeded), (iii) involve slab
            penetrations or curtain wall penetrations in the Building or Garage,
            (iv) penetrate into portions of the Building outside of the
            Premises, or (iv) adversely affect (A) the functioning of the
            Building HVAC system, or the electrical, mechanical, plumbing,
            lighting, life safety or any other system of the Building or (B)
            Landlord's ability to deliver Building services to other tenants of
            the Building. As to Installations not covered by the preceding
            sentence, Tenant will not perform same without the prior written
            consent of Landlord, which consent shall not be unreasonably
            withheld, conditioned or delayed. All Installations shall be at
            Tenant's sole cost and expense. Without in any way limiting
            Landlord's consent rights, Tenant shall not be permitted to proceed
            until (a) Landlord approves the contractor or person making such
            Installations and approves such contractor's insurance coverage to
            be provided in connection with the work, (b) Landlord approves final
            and complete plans and specifications for the work and (c) the
            appropriate governmental agency, if any, has approved the plans and
            specifications for such work. All work performed by Tenant or its
            contractor relating to the Installations shall conform to applicable
            governmental laws, rules and regulations, including, without
            limitation, the Disability Acts. Upon completion of the
            Installations, Tenant shall deliver to Landlord "as built" plans. If
            Landlord performs such Installations, Tenant shall pay Landlord, as
            Additional Rent, the cost thereof plus fifteen percent (15%) as
            reimbursement for Landlord's overhead. Each payment shall be made to
            Landlord within ten (10) days after receipt of an invoice from
            Landlord. All Installations that constitute improvements constructed
            within the Premises shall be surrendered with the Premises at the
            expiration or earlier termination of this Lease, unless Landlord
            requests that same be removed pursuant to Section 1.3 above. Tenant
            shall indemnify and hold Landlord harmless from, and reimburse
            Landlord for and with respect to, any and all costs, expenses
            (including reasonable attorneys' fees and court costs), demands,
            claims, causes of action and liens arising from or in connection
            with any Installations performed by or on behalf of Tenant. All
            Installations performed by or on behalf of Tenant will be performed
            diligently and in a first-class workmanlike manner and in compliance
            with all applicable laws, ordinances, regulations and rules of any
            public authority having jurisdiction over the Building and/or
            Tenant's and Landlord's insurance carriers. Landlord will have the
            right, but not the obligation, to inspect periodically the work on
            the Premises and may require reasonable changes in the method or
            quality of the work.

            construction of improvements (including, without limitation,
            Tenant's Improvements) in the Premises shall not in any way be
            construed as or constitute a representation or warranty of Landlord
            as to the abilities of the contractor or the adequacy or sufficiency
            of such drawings, plans or specifications or the improvements to
            which they relate, for any use, purpose or condition.

                          INSURANCE, FIRE AND CASUALTY

SECTION 7.1 TOTAL OR PARTIAL DESTRUCTION OF THE BUILDING OR THE PREMISES. In the
event that the Building is totally destroyed by fire or other casualty or in the
event the Building (or any portion thereof) is so damaged that the Premises will
be, in Landlord's reasonable opinion, unfit for occupancy (as defined in Section
5.202 hereof) for a period exceeding one hundred eighty (180) days after the
date of such damage, Landlord or Tenant may terminate this Lease, in which event
Basic Annual Rent and Additional Rent shall be abated during the unexpired
portion of this Lease effective with the date of such damage. Landlord or Tenant
shall exercise the termination right pursuant to the preceding sentence, if at
all, by delivering written notice of termination within ten (10) days after
Landlord's determination given to Tenant in writing that the repairs cannot be
completed within such one hundred eighty (180) day period. In the event the
Building or the Premises are damaged by fire or other casualty and, in
Landlord's reasonable opinion, the Premises can be made tenantable within one
hundred eighty (180) days after the date of such damage, or if the damage is
more serious but neither Landlord nor Tenant elects to terminate this Lease
pursuant to this Section, in either such event Landlord shall, within sixty (60)
days after the date of such damage, commence rebuilding or repairing the
Building and the Premises (including Tenant's Improvements), but only to the
extent of insurance proceeds actually received by Landlord for such repairs, to
substantially the same condition which existed immediately prior to the
happening of the casualty. Landlord shall allow Tenant a fair diminution of
Basic Annual Rent and Additional Rent during the time the Premises are unfit for
occupancy; provided, that if such casualty was caused by Tenant, its agents,
employees, or contractors, Basic Annual Rent and Additional Rent shall be abated
only to the extent Landlord is compensated for such Basic Annual Rent and
Additional Rent by loss of rents insurance, if any. Notwithstanding any
provision or inference herein to the contrary, Landlord's obligation to restore
the Building and the Premises is expressly limited to the amount of casualty
insurance proceeds actually received by Landlord. Without limiting the preceding
sentence, Tenant understands and agrees that if any mortgagee under a deed of
trust, security agreement or mortgage on the Building should require that the
insurance proceeds be used to retire or reduce the mortgage debt or if the
insurance company issuing Landlord's fire and casualty insurance policy fails or
refuses to pay Landlord the proceeds under such policy, Landlord shall have no
obligation to rebuild and this Lease shall terminate upon notice by Landlord to
Tenant. Any insurance which may be carried by Landlord or Tenant against loss or
damage to the Building or to the Premises shall be for the sole benefit of the
party carrying such insurance and under its sole control.

                  Installations and all other fixtures, equipment and personalty
                  located in the Premises. Such policy will be written in the
                  names of Tenant, Landlord and any other parties reasonably
                  designated by Landlord from time to time, as their respective
                  interests may appear. The property insurance may, with the
                  consent of the Landlord, provide for a reasonable deductible.

            and/or the Premises) and (d) Tenant's insurance is primary in the
            event of overlapping coverage which may be carried by Landlord.

7.203       Proof of Insurance. Tenant shall deliver to Landlord certified
            copies of all policies of insurance required by this Section 7.2 or
            duly executed Certificates of Insurance evidencing in-force coverage

            shall have no rights in any policy or policies maintained by
            Landlord.

negligence or other tortious conduct, acts or omissions of the released party or
the released party's directors, employees, agents or invitees), to their
respective property, the Premises, its contents or to any other portion of the
Building or the Property arising from any risk covered by the fire and extended

party. Without in any way limiting the foregoing waivers and to the extent
permitted by applicable law, the parties hereto each, on behalf of their
respective insurance companies insuring the property of either Landlord or
Tenant against any such loss, waive any right of subrogation that Landlord or
Tenant or their respective insurers may have against the other party or their
respective officers, directors, employees, agents or invitees and all rights of
their respective insurance companies based upon an assignment from its insured.
Each party to this Lease agrees immediately to give to each such insurance
company written notification of the terms of the mutual waivers contained in

Property or any portion thereof that, in Landlord's reasonable opinion, is
necessary to the continued efficient and/or economically feasible use of the
Property shall be taken or condemned in whole or in part for public purposes, or
sold to a condemning authority in lieu of taking, then the term of this Lease
shall, at the option of Landlord, forthwith cease and terminate.

SECTION 8.2 TOTAL CONDEMNATION OF PREMISES. In the event that all or
substantially all of the Premises is taken or condemned or sold in lieu thereof
or if Tenant will be unable to use a substantial portion of the Premises or it
is reasonably anticipated that safe and reasonable access to the Building will
not be available or that Tenant's use of the Premises in the manner used
immediately prior to such taking will be substantially impaired for a period of
one hundred eighty (180) consecutive days by reason of a taking, either Landlord
or Tenant may terminate this Lease by delivering written notice thereof to the
other within ten (10) business days after notice of the taking, condemnation or
sale in lieu thereof to be effective as of the date of such taking, condemnation
or sale in lieu thereof.

SECTION 8.3 CONDEMNATION WITHOUT TERMINATION. If upon a taking or condemnation
or sale in lieu of the taking of all or less than all of the Property which (a)
does not give either Landlord or Tenant the right to terminate this Lease or (b)
gives either Landlord or Tenant the right to terminate this Lease pursuant to
Section 8.1 or 8.2 above and neither Landlord nor Tenant elect to exercise such
termination right, then this Lease shall continue in full force and effect,
provided that, if the taking, condemnation or sale includes any portion of the
Premises, the Basic Annual Rent and Additional Rent shall be redetermined on the
basis of the remaining square feet of Agreed Rentable Area of the Premises.
Landlord, at Landlord's sole option and expense, shall restore and reconstruct
the Building to substantially its former condition to the extent that the same
may be reasonably feasible, but such work shall not be required to exceed the
scope of the work done by Landlord in originally constructing


                                       17
<PAGE>   27

the Building, nor shall Landlord in any event be required to spend for such work
an amount in excess of the amount received by Landlord as compensation or
damages (over and above amounts going to the mortgagee of the property taken)
for the part of the Building or the Premises so taken.

SECTION 8.4 CONDEMNATION PROCEEDS. Landlord shall receive the entire award
(which shall include sales proceeds) payable as a result of a condemnation,
taking or sale in lieu thereof. Tenant hereby expressly assigns to Landlord any
and all right, title and interest of Tenant now or hereafter arising in and to
any such award. Tenant shall, however, have the right to recover from such
authority through a separate award which does not reduce Landlord's award, any
compensation as may be awarded to Tenant on account of moving and relocation
expenses and depreciation to and removal of Tenant's physical property.

                                    ARTICLE 9
                                      LIENS

Tenant shall keep the Premises free from all liens arising out of any work
performed, materials furnished or obligations incurred by or for Tenant and
Tenant shall indemnify and hold Landlord harmless from, and reimburse Landlord
for and with respect to, any and all claims, causes of action, damages, expenses
(including reasonable attorneys' fees), arising from or in connection with any
such liens. In the event that Tenant shall not, within ten (10) days following
notification to Tenant of the imposition of any such lien, cause the same to be
released of record by payment or the posting of a bond in amount, form and
substance reasonably acceptable to Landlord, Landlord shall have, in addition to
all other remedies provided herein and by law, the right but not the obligation,
to cause the same to be released by such means as it shall deem proper,
including payment of or defense against the Claim giving rise to such lien. All
amounts paid or incurred by Landlord in connection therewith shall be paid by
Tenant to Landlord on demand and shall bear interest from the date of demand
until paid at the rate set forth in Section 15.10 below. Nothing in this Lease
shall be deemed or construed in any way as constituting the consent or request
of Landlord, express or implied, by inference or otherwise, to any contractor,
subcontractor, laborer or materialman for the performance of any labor or the
furnishing of any materials for any specific improvement, alteration or repair
of or to the Building or the Premises or any part thereof, nor as giving Tenant
any right, power or authority to contract for or permit the rendering of any
services or the furnishing of any materials that would give rise to the filing
of any mechanic's or other liens against the interest of Landlord in the
Property or the Premises.

                                   ARTICLE 10
                           TAXES ON TENANT'S PROPERTY

Tenant shall be liable for and shall pay, prior to their becoming delinquent,
any and all taxes and assessments levied against, and any increases in Real
Estate Taxes as a result of, any personal property or trade or other fixtures
placed by Tenant in or about the Premises and any improvements (other than
Tenant's Improvements) constructed in the Premises by or on behalf of Tenant.

                                   ARTICLE 11
                            SUBLETTING AND ASSIGNING

SECTION 11.1 SUBLEASE AND ASSIGNMENT. Tenant shall not assign this Lease, or
allow it to be assigned, in whole or in part, by operation of law or otherwise
(it being agreed that for purposes of this Lease, assignment shall include,
without limitation, the transfer of a majority interest of stock, partnership or
other forms of ownership interests, merger or dissolution) or mortgage or pledge
the same, or sublet the Premises or any part thereof or permit the Premises to
be occupied by any firm, person, partnership or corporation or any combination
thereof, other than Tenant, without the prior written consent of Landlord. In no
event shall any assignment or sublease ever release Tenant from any obligation
or liability hereunder.

SECTION 11.2 TENANT'S CONTINUING OBLIGATIONS. Without limiting Landlord's
consent rights and as a condition to obtaining Landlord's consent, (i) each
assignee must assume all obligations under this Lease and (ii) each subtenant
must confirm that its sublease is subject and subordinate to this Lease. In
addition, each assignee and subtenant shall agree to cause the Premises to
comply at all times with all requirements of the Disability Acts


                                       18
<PAGE>   28

(as amended), including, but not limited to, obligations arising out of or
associated with such assignee's or subtenant's use of or activities or business
operations conducted within the Premises. No assignee or subtenant of the
Premises or any portion thereof may assign or sublet the Premises or any portion
thereof. Consent by Landlord to one or more assignments or sublettings shall not
operate as a waiver of Landlord's rights as to any subsequent assignments and/or
sublettings. All reasonable legal fees and expenses incurred by Landlord in
connection with any assignment or sublease proposed by Tenant will be the
responsibility of Tenant and will be paid by Tenant upon receipt of an invoice
from Landlord.

SECTION 11.3 LANDLORD'S RIGHTS RELATING TO ASSIGNEE OR SUBTENANT. To the extent
the rentals or income derived from any sublease or assignment exceed the rentals
due hereunder, all such excess rentals (after first deducting all reasonable
costs associated with such sublease or assignment) shall be the property of and
paid over to Landlord in consideration for Landlord's consent to the applicable
assignment or sublease. Landlord may at its option collect directly from such
assignee or subtenant all rents becoming due to Tenant under such assignment or
sublease. Tenant here by authorizes and directs any such assignee or subtenant
to make such payments of rent directly to Landlord upon receipt of notice from
Landlord, and Tenant agrees that any such payments made by an assignee or
subtenant to Landlord shall, to the extent of the payments so made, be a full
and complete release and discharge of rent owed to Tenant by such assignee or
subtenant. No direct collection by Landlord from any such assignee or subtenant
shall be construed to constitute a novation or a release of Tenant or any
guarantor of Tenant from the further performance of its obligations hereunder.
Receipt by Landlord of any rent from any assignee, subtenant or occupant of the
Premises or any part thereof shall not be deemed a waiver of the above covenant
in this Lease against assignment and subletting or a release of Tenant under
this Lease. In the event that, following an assignment or subletting, this Lease
or the rights and obligations of Tenant hereunder are terminated for any reason,
including without limitation in connection with default by or bankruptcy of
Tenant (which, for the purposes of this Section 11.3, shall include all persons
or entities claiming by or through Tenant), Landlord may, at its sole option,
consider this Lease to be thereafter a direct lease to the assignee or subtenant
of Tenant upon the terms and conditions contained in this Lease.

SECTION 11.4 ERISA AND UBTI RESTRICTIONS. Notwithstanding anything to the
contrary contained herein, including, without limitation Sections 11.1 and 11.2
above, no assignment or subletting shall be permitted if (i) the proposed
assignee or subtenant or any person which, directly or indirectly, controls, is
controlled by, or is under common control with, the proposed assignee or
subtenant directly or indirectly, controls, is controlled by, or is under common
control with Landlord or any person who controls Landlord; and (ii) the proposed
assignment or sublease (1) provides for a rental or other payment for the
leasing, use, occupancy or utilization of all or any portion of the Premises
based, in whole or in part, on the income or profits derived by any person from
the property so leased, used, occupied or utilized other than an amount based on
a fixed percentage or percentages of gross receipts or sales or (2) does not
provide that such assignee or subtenant shall not enter into any lease,
sublease, license, concession or other agreement for the use, occupancy or
utilization of all or any portion of the Premises which provides for a rental or
other payment for such use, occupancy or utilization based, in whole or in part,
on the income or profits derived by any person from the property so leased,
used, occupied or utilized other than an amount based on a fixed percentage or
percentages of gross receipts or sales; or (iii) in the reasonable opinion of
Landlord's counsel, such proposed assignment or subletting will (1) cause a
violation of the Employee Retirement Income Security Act of 1974 by such
proposed assignee or subtenant, by Landlord, or by any person which, directly or
indirectly, controls, is controlled by, or is under common control with,
Landlord or any person who controls Landlord or (2) result in Landlord, or any
person which, directly or indirectly controls Landlord, receiving "unrelated
business taxable income" (as defined in the Internal Revenue Code).

SECTION 11.5 ASSIGNMENT BY OPERATION OF LAW. The dissolution of a corporation or
partnership which is Tenant, the transfer of a majority of the assets of Tenant,
the addition and withdrawal of shareholders in a corporation which is Tenant and
the withdrawal from and addition of partners to any partnership which is Tenant
shall constitute an assignment of this Lease which is prohibited without
Landlord's consent. However, notwithstanding the foregoing and for purposes of
this Lease, the following shall not be considered assignments prohibited
hereunder or otherwise require Landlord's consent: (1) the dissolution of Tenant
(if Tenant is a partnership) and immediate reconstitution into a partnership or
the addition or withdrawal of partners, or the reallocation of interests among
partners of Tenant; (2) the dissolution of Tenant (if Tenant is a corporation)
and the


                                       19
<PAGE>   29

immediate reconstitution of Tenant into a new corporation, or the addition of
stockholders and the withdrawal of stockholders in the normal course of Tenant's
business, (3) the assignment of this Lease to any successor of Tenant (A) into
which or with which Tenant is merged or consolidated, (B) arising from the
transfer of Tenant's interest under this Lease made in conjunction with the
transfer of a majority of the assets and liabilities of Tenant, or (C) arising
from the acquisition of the assets and liabilities of another corporation by
Tenant so long as in each of the circumstances described in (1) through (3)
above the surviving partnership, corporation or assignee shall assume all
obligations of Tenant hereunder and include a majority of the partners that were
partners (in the case of a partnership) or include the same controlling
shareholders (in the case of a corporation) of Tenant during the twelve (12)
month period immediately prior to the time of the applicable event and the
surviving partnership, corporation or assignee can demonstrate to Landlord's
reasonable satisfaction the same or better financial strength as possessed by
Tenant on the date hereof. Further, Landlord agrees to not unreasonably withhold
or delay its consent to any proposed sublease or assignment to an Affiliate of
Tenant.

                    TRANSFERS BY LANDLORD, SUBORDINATION AND
                          TENANT'S ESTOPPEL CERTIFICATE

SECTION 12.1 SALE OF THE PROPERTY. In the event of a sale, transfer or
conveyance by Landlord of the Property (which sale, transfer or conveyance by
Landlord may be consummated freely without consent or approval of Tenant), the
same shall operate to release Landlord from any and all liability under this
Lease arising after the date of such sale, provided that if a Security Deposit
has been made by Tenant, Landlord shall not be released from liability with
respect thereto unless Landlord transfers the Security Deposit to the purchaser.

SECTION 12.2 SUBORDINATION, ATTORNMENT AND NOTICE. This Lease is subject and
subordinate to (i) any lease wherein Landlord is the tenant and to the liens of
any and all mortgages and deeds of trust, regardless of whether such lease,
mortgage or deed of trust now exists or may hereafter be created with regard to
all or any part of the Property, (ii) any and all advances (including interest
thereon) to be made under any such lease, mortgage or deed of trust and (iii)
all modifications, consolidations, renewals, replacements and extensions of any
such lease, mortgage or deed of trust. Tenant also agrees that any lessor,
mortgagee or trustee may elect (which election shall be revocable) to have this
Lease superior to any lease or lien of its mortgage or deed of trust and, in the
event of such election and upon notification by such lessor, mortgagee or
trustee to Tenant to that effect, this Lease shall be deemed superior to the
said lease, mortgage or deed of trust, whether this Lease is dated prior to or
subsequent to the date of said lease, mortgage or deed of trust. Tenant shall,
in the event of the sale or assignment of Landlord's interest in the Premises
(except in a sale-leaseback financing transaction), or in the event of the
termination of any lease in a sale-leaseback financing transaction wherein
Landlord is the lessee, attorn to and recognize such purchaser, assignee or
mortgagee as Landlord under this Lease. Tenant shall, in the event of any
proceedings brought for the foreclosure of, or in the event of the exercise of
the power of sale under, any mortgage or deed of trust covering the Premises,
attorn to and recognize purchaser at such sale, assignee or mortgagee, as the
case may be, as Landlord under this Lease. The above subordination and
attornment clauses shall be self-operative and no further instruments of
subordination or attornment need be required by any mortgagee, trustee, lessor,
purchaser or assignee. In confirmation thereof, Tenant agrees that, upon the
request of Landlord, or any such lessor, mortgagee, trustee, purchaser or
assignee, Tenant shall execute and deliver whatever instruments may be required
for such purposes and to carry out the intent of this Section 12.2. If an
Affiliate of Landlord shall be the mortgagee, then it shall be an express
condition precedent to the effectiveness of the agreement to subordinate set
forth in this Section 12.2 that Landlord obtain from Landlord's mortgagee an
agreement, on mortgagee's standard form, that, notwithstanding any foreclosure
by Landlord's mortgagee's, or deed, or other conveyance in lieu of foreclosure
with respect thereto, Tenant's leasehold estate created hereunder and Tenant's
other options and rights arising out of this Lease should not be disturbed or
affected so long as no default by Tenant exists under the terms of this Lease
(after notice and opportunity to cure as provided herein).

SECTION 12.3 TENANT'S ESTOPPEL CERTIFICATE. Tenant shall, upon the request of
Landlord or any mortgagee of Landlord, without additional consideration, deliver
an estoppel certificate, consisting of reasonable statements required by
Landlord, any mortgagee or purchaser of any interest in the Property, which
statements may include but shall not be limited to the following: this Lease is
in full force and effect, with rental paid through [a


                                       20

current date]; this Lease has not been modified or amended; Landlord is not in
default and Landlord has fully performed all of Landlord's obligations
hereunder; and such other statements as may reasonably be required by the
requesting party. If Tenant is unable to make any of the statements contained in
the estoppel certificate because the same is untrue, Tenant shall with
specificity state the reason why such statement is untrue. Tenant shall, if
requested by Landlord or any such mortgagee, deliver to Landlord a fully
executed instrument in form reasonably satisfactory to Landlord evidencing the
agreement of Tenant to the mortgage or other hypothecation by Landlord of the
interest of Landlord hereunder.

this Lease.

13.101      Failure to Pay Rent. Any failure by Tenant to pay Rent or to make
            any other payment required to be made by Tenant hereunder within
            five (5) days following written notice to Tenant; however, no notice
            shall be required for default in payment of Rent after the second
            such monetary default during any twelve (12) month period.

13.102      Failure to Perform. Except for a failure covered by subsection
            13.101 above or 13.103 below, any failure by Tenant to observe and
            perform any provision of this Lease to be observed or performed by
            Tenant where such failure continues for thirty (30) days after
            written notice to Tenant, provided that if such failure cannot be
            cured within said thirty (30) day period, Tenant shall not be in
            default hereunder so long as Tenant commences curative action within
            such thirty (30) day period, diligently and continuously pursues the
            curative action and fully and completely cures the failure within
            ninety (90) days after such written notice to Tenant. However, such
            ninety (90) days may be extended as necessary if the default does
            not adversely impact the Building operations or Building systems or
            any other tenant in the Building and so long as Tenant diligently
            and continuously pursues the curative action.

            twelve (12) month period to perform and observe a particular
            provision of this Lease to be observed or performed by Tenant (other
            than the failure to pay Rent, which in all instances will be covered
            by subsection 13.101 above), no notice being required for any such
            third failure.

13.104      Bankruptcy, Insolvency, Etc. Tenant or any guarantor of Tenant's
            obligations hereunder (hereinafter called "Guarantor", whether one
            (1) or more), (i) cannot meet its obligations as they become due,
            (ii) becomes or is declared insolvent according to any law, (iii)
            makes a transfer in fraud of creditors according to any applicable
            law, (iv) assigns or conveys all or a substantial portion of its
            property for the benefit of creditors or (v) files a petition for
            relief under the Federal Bankruptcy Code or any other present or
            future federal or state insolvency, bankruptcy or similar law
            (collectively, "applicable bankruptcy law"); a receiver or trustee
            is appointed for Tenant or Guarantor or its property; the interest
            of Tenant or Guarantor under this Lease is levied on under execution
            or under other legal process; any involuntary petition is filed
            against Tenant or Guarantor under applicable bankruptcy law; or any
            action is taken to reorganize or modify Tenant's or Guarantor's
            capital structure if Tenant or Guarantor is a corporation or other
            entity (provided that no such levy, execution, legal process or
            petition filed against Tenant or Guarantor shall constitute a breach
            of this lease if Tenant or Guarantor shall vigorously contest the
            same by appropriate proceedings and shall remove or vacate the same
            within ninety (90) days from the date of its creation, service or
            filing).

13.105      Loss of Right to do Business. If Tenant is a corporation or limited
            partnership, Tenant fails to maintain its right to do business in
            the State of Texas or fails to pay any applicable annual


                                       21
<PAGE>   31

            franchise taxes as and when same become finally due and payable and
            such failure continues for a period of thirty (30) days after
            written notice of same from Landlord to Tenant.

13.106      Dissolution or Liquidation. If Tenant is a corporation or
            partnership, Tenant dissolves or liquidates or otherwise fails to

SECTION 13.2 REMEDIES OF LANDLORD.

13.201      Termination of the Lease. Upon the occurrence of a default by Tenant
            hereunder, Landlord may, without judicial process, terminate this
            Lease by giving written notice thereof to Tenant (whereupon all
            obligations and liabilities of Landlord hereunder shall terminate)
            and, without further notice and without liability, repossess the
            Premises. Landlord shall be entitled to recover all loss and damage
            Landlord may suffer by reason of such termination, whether through
            inability to relet the Premises on satisfactory terms or otherwise,
            including without limitation, the following (without duplication of
            any element of damages):

                  (1)   accrued Rent to the date of termination and Late
                        Charges, plus interest thereon at the rate established
                        under Section 15.10 below from the date due through the
                        date paid or date of any judgment or award by any court
                        of competent jurisdiction, the unamortized cost of
                        Tenant's Improvements, brokers' fees and commissions,
                        attorneys' fees, moving allowances and any other costs
                        incurred by Landlord in connection with making or
                        executing this Lease, the cost of recovering the
                        Premises and the costs of reletting the Premises
                        (including, without limitation, advertising costs,
                        brokerage fees, leasing commissions, reasonable
                        attorneys' fees and refurbishing costs and other costs
                        in readying the Premises for a new tenant);

                  (2)   the present value of the Rent (discounted at a rate of
                        interest equal to six percent [6%] per annum [the
                        "Discount Rate"]) that would have accrued under this
                        Lease for the balance of the Lease term but for such
                        termination, reduced by the reasonable fair market
                        rental value of the Premises for such balance of the
                        Lease term (determined from the present value of the
                        actual base rents, discounted at the Discount Rate,
                        received and to be received from Landlord's reletting of
                        the Premises or, if the Premises are not relet, the base
                        rents, discounted at the Discount Rate, that would be
                        received from a comparable lease and comparable tenant
                        for a comparable term and taking into account among
                        other things, the condition of the Premises, market
                        conditions and the period of time the Premises may
                        reasonably remain vacant before Landlord is able to
                        re-lease the same to a suitable replacement tenant, it
                        being agreed that Landlord shall have no obligation to
                        relet or attempt to relet the Premises);

                  (3)   plus any other costs or amounts necessary to compensate
                        Landlord for its damages.

13.202      Repossession and Re-Entry. Upon the occurrence of a default by
            Tenant hereunder, Landlord may, without judicial process,
            immediately terminate Tenant's right of possession of the Premises
            (whereupon all obligations and liability of Landlord hereunder shall
            terminate), but not terminate this Lease, and, without notice,
            demand or liability, enter upon the Premises or any part thereof,
            take absolute possession of the same, expel or remove Tenant and any
            other person or entity who may be occupying the Premises and change
            the locks. If Landlord terminates Tenant's possession of the
            Premises under this subsection 13.202, (i) Landlord shall have no
            obligation whatsoever to tender to Tenant a key for new locks
            installed in the Premises, (ii) Tenant shall have no further right
            to possession of the Premises and (iii) Landlord shall have no
            obligation whatsoever to relet or attempt to relet the Premises.
            Landlord may, however, at its sole option relet the Premises or


                                       22
<PAGE>   32

            any part thereof for such terms and such rents as Landlord may in
            its sole discretion elect. If Landlord elects to relet the Premises,
            rent received by Landlord from such reletting shall be applied
            first, to the payment of any indebtedness other than Rent due
            hereunder from Tenant to Landlord (in such order as Landlord shall
            designate), second, to the payment of any costs of such reletting,
            including, without limitation, refurbishing costs, reasonable
            attorneys' fees, advertising costs, brokerage fees and leasing
            commissions and third, to the payment of Rent due and unpaid
            hereunder (in such order as Landlord shall designate), and Tenant
            shall satisfy and pay to Landlord any deficiency upon demand
            therefor from time to time. Landlord shall not be responsible or
            liable for any failure to relet the Premises or any part thereof or
            for any failure to collect any rent due upon any such reletting. No
            such re-entry or taking of possession of the Premises by Landlord
            shall be construed as an election on Landlord's part to terminate
            this Lease unless a written notice of such termination is given to
            Tenant pursuant to subsection 13.201 above. If Landlord relets the
            Premises, either before or after the termination of this Lease, all
            such rentals received from such lease shall be and remain the
            exclusive property of Landlord, and Tenant shall not be, at any
            time, entitled to recover any such rental. Landlord may at any time
            after a reletting elect to terminate this Lease.

13.203      Cure of Default. Upon the occurrence of a default hereunder by
            Tenant, Landlord may, without judicial process and without having
            any liability therefor, enter upon the Premises and do whatever
            Tenant is obligated to do under the terms of this Lease and Tenant
            agrees to reimburse Landlord on demand for any expenses which
            Landlord may incur in effecting compliance with Tenant's obligations
            under this Lease, and Tenant further agrees that Landlord shall not
            be liable for any damages resulting to Tenant from such action,
            whether caused by the negligence of Landlord, its agents, employees,
            contractors or otherwise.

13.204      Continuing Obligations. No repossession of or re-entering upon the
            Premises or any part thereof pursuant to subsection 13.202 or 13.203
            above or otherwise and no reletting of the Premises or any part
            thereof pursuant to subsection 13.202 above shall relieve Tenant or
            any Guarantor of its liabilities and obligations hereunder, all of
            which shall survive such repossession or re-entering. In the event
            of any such repossession of or re-entering upon the Premises or any
            part thereof by reason of the occurrence of a default, Tenant will
            continue to pay to Landlord Rent required to be paid by Tenant.

13.205      Cumulative Remedies. No right or remedy herein conferred upon or
            reserved to Landlord is intended to be exclusive of any other right
            or remedy set forth herein or otherwise available to Landlord at law
            or in equity and each and every right and remedy shall be cumulative
            and in addition to any other right or remedy given hereunder or now
            or hereafter existing at law or in equity or by statute. In addition
            to the other remedies provided in this Lease and without limiting
            the preceding sentence, Landlord shall be entitled, to the extent
            permitted by applicable law, to injunctive relief in case of the
            violation, or attempted or threatened violation, of any of the
            covenants, agreements, conditions or provisions of this Lease, or to
            a decree compelling performance of any of the covenants, agreements,
            conditions or provisions of this Lease, or to any other remedy
            allowed to Landlord at law or in equity.

SECTION 13.3. DEFAULTS BY LANDLORD, Landlord shall be in default under this
Lease if and only if Landlord fails to perform any of its obligations hereunder
and said failure continues for a period of thirty (30) days after Tenant
delivers written notice thereof to Landlord and each mortgagee who has a lien
against any portion of the Property and whose name and address has been provided
to Tenant, provided that if such failure cannot reasonably be cured within said
thirty (30) day period, Landlord shall not be in default hereunder if the
curative action is commenced within said thirty (30) day period and is
thereafter diligently pursued until cured. In no event shall (i) Tenant claim a
constructive or actual eviction or that the Premises have become unsuitable
hereunder or (ii) a constructive or actual eviction or breach of any implied
warranty be deemed to have occurred under this Lease, prior to the expiration of
the notice and cure periods provided under this Section 13.3. Any notice of a
failure to perform by Landlord shall be sent to Landlord at the addresses and to
the attention of the parties set forth


                                       23
<PAGE>   33

in the Basic Lease Provisions. Any notice of a failure to perform by Landlord
not sent to Landlord at all addresses and/or to the attention of all parties
required under this Section and to each mortgagee who is entitled to notice or
not sent in compliance with Article 14 below shall be of no force or effect.

SECTION 13.4 LANDLORD'S LIABILITY.

13.401      Tenant's Rights in Respect of Landlord Default. Tenant is granted no
            contractual right of termination by this Lease, except to the extent
            and only to the extent set forth in Sections 5.202, 7.1 and 8.2
            above and Section 13.7 below. If Tenant shall recover a money
            judgment against Landlord, such judgment shall be satisfied only out
            of the right, title and interest of Landlord in the Property (as the
            same may then be encumbered) and, subject to the rights of
            mortgagees, any insurance carried in the name of Landlord and
            Landlord shall not be liable for any deficiency. If Landlord is
            found to be in default hereunder by reason of its failure to give a
            consent that it is required to give hereunder, Tenant's sole remedy
            will be an action for specific performance or injunction. The
            foregoing sentence shall in no event be construed as mandatorily
            requiring Landlord to give consents under this Lease. In no event
            shall either Landlord or Tenant be liable to the other for
            consequential or special damages by reason of a failure to perform
            (or a default) by the respective party hereunder. In no event shall
            Tenant have the right to levy execution against any property of
            Landlord other than its interest in the Property as hereinbefore
            expressly provided.

13.402      Certain Limitations on Landlord's Liability. Unless caused by
            Landlord's gross negligence or willful misconduct and without
            limiting the provisions of Section 7.4, Landlord shall not be liable
            to Tenant for any claims, actions, demands, costs, expenses, damage
            or liability of any kind (i) arising out of the use, occupancy or
            enjoyment of the Premises by Tenant or any person therein or holding
            under Tenant or by or through the acts or omissions of any of their
            respective employees, officers, agents, invitees or contractors,
            (ii) caused by or arising out of fire, explosion, falling sheetrock,
            gas, electricity, water, rain, snow or dampness, or leaks in any
            part of the Premises, (iii) caused by or arising out of damage to
            the roof, pipes, appliances or plumbing works or any damage to or
            malfunction of heating, ventilation or air conditioning equipment or
            (iv) caused by Tenants or any persons either in the Premises or
            elsewhere in the Building (other than Common Areas) or by occupants
            of property adjacent to the Building or Common Areas or by the
            public or by the construction of any private, public or quasi-public
            work. In no event shall Landlord be liable to Tenant for any loss of
            or damage to property of Tenant or of others located in the Premises
            or the Building by reason of theft or burglary.

                  significantly disparate bargaining position with respect to
                  this Lease and the transaction evidenced hereby.

            (2)   Tenant represents to Landlord that Tenant is represented by

                  Lease, Tenant is a business consumer as that term is used in
                  the DTPA (i.e., Tenant is an individual, partnership or
                  corporation who seeks or acquires by purchase or lease, any
                  goods or services for commercial or business use).

            (4)   Landlord and Tenant agree that the total consideration paid or

                  million or more according to the most recent financial
                  statement of Tenant prepared in accordance with generally
                  accepted accounting principles, failing which Landlord and
                  Tenant shall have their respective legal counsel sign this
                  Lease in the space provided on the signature page hereof.
                  Tenant further represents that it has knowledge and experience
                  in financial and business matters that enable it to evaluate
                  the merits and risks of this transaction.

                  agents, property managers, brokers and contractors and their
                  respective heirs, personal representatives, successors and
                  assigns, that all of the provisions of the DTPA (except for
                  Section 17.555 thereof) which are or may be applicable to this
                  Lease and the transaction evidenced hereby are hereby waived,
                  including specifically, without limitation, all rights and
                  remedies resulting from or arising out of any and all acts or

                  of this Lease. The provisions of this Section shall survive
                  the execution and any termination of this Lease.

SECTION 13.7 LEASE CANCELLATION OPTIONS.

13.701      Initial Cancellation Options. Tenant shall have two (2) options to
            terminate this Lease, such termination to be effective at the
            expiration of the twenty-fourth (24th) full calendar month following
            the Commencement Date or the thirty-sixth (36th) full calendar month
            following the Commencement Date, respectively (each a "Termination
            Date") by providing written notice to Landlord no later than six (6)
            full calendar months prior to the applicable Termination Date and by
            paying to Landlord on or prior to the applicable Termination Date,
            the Cancellation Payment. The term "Cancellation Payment" shall mean
            an amount, as of the Termination Date, equal to Landlord's
            unamortized leasing costs, which shall consist of the remaining book
            balance of the sum of the following costs, based on straight line
            depreciation over the initial Term using a 10% interest factor:

                  (i)   the Finish Allowance provided for in Exhibit C: and

                  (ii)  all amounts due to brokers or other third parties in
                        connection with the Lease

            , all as more specifically shown on Exhibit F, attached hereto and
            made a part hereof. Notwithstanding the foregoing, Tenant's right to
            terminate the Lease may not be exercised unless (a) Landlord is
            unable to accommodate Tenant's actual expansion requirements on
            Floor 7 of the Building within one hundred eighty (180) days after
            written notice from Tenant of its good faith actual expansion needs,
            or (b) Tenant or any subsequent permitted third party nonaffiliated
            assignee of Tenant's rights hereunder completely ceases doing
            business in any form.

13.702      Additional Cancellation Option. In addition to the lease
            cancellation options granted above, Tenant shall have a third option
            to terminate the Lease at any time after the end of the second
            annual

            anniversary of the Commencement Date and until six (6) months prior
            to the expiration of the Initial Term, to be exercised in the manner
            provided for in Section 13.701 above in the event that (a)
            substantially all of the assets of Tenant are sold or 50 percent or
            more of the voting stock of Tenant is sold or transferred, in each
            instance as part of an arms length sale to a bonafide third party
            that is unaffiliated with Tenant in any respect, and (b) thereafter,
            Tenant's principal place of business operation shall be moved to a
            location that is outside Harris County, Texas or any county
            adjoining Harris County. In such event, and in addition to the
            Cancellation Payment provided for in Section 13.701 above, Tenant
            shall pay an additional payment ("Relocation Cancellation Payment")
            equal to (6) months of Basic Rent as provided for in this Lease.

SECTION 13.8 SATELLITE DISH. Tenant may, at Tenant's sole cost and expense
(including any above Building standard utilities used therefor), construct,
install, operate and secure no more than one (1) satellite antenna on the roof
of the Building in an area designated by Landlord (the "Satellite") and the
necessary cabling from the Satellite to the Premises, all in accordance with
specifications approved by Landlord (the "Satellite System"). Landlord shall
charge Tenant for the lease of the roof space at the current rate generally
prevailing from time to time for other tenants in the Building. The Satellite
System shall be for Tenant's sole use and not for use by others. Landlord may
cause Tenant to relocate the Satellite on the roof of the Building from time to
time at Tenant's expense if required for maintenance purposes or if required by
law or upon request by Landlord because of any other cause beyond Landlord's
control. Tenant agrees to install, use, and maintain the Satellite System so as
not to interfere with other operations from the roof of the Building, including
existing satellite or antenna transmissions, and in full compliance with all
applicable laws including rules, regulations, and guidelines promulgated by the
Federal Communications Commission, and Tenant agrees to indemnify and hold
Landlord harmless from and against all costs (including attorneys' fees and
court costs), claims, liabilities or obligations arising from the placement,
construction or use of the Satellite System. Tenant shall maintain the Satellite
System in good condition and shall, at the end of the Term, remove the Satellite
System and all related improvements installed by Tenant and repair all damage to
the roof caused by such removal.

SECTION 15.3 NO WAIVER. No waiver by Landlord or by Tenant of any provision of
this Lease shall be deemed to be a waiver by either party of any other provision
of this Lease. No waiver by Landlord of any breach by Tenant shall be deemed a
waiver of any subsequent breach by Tenant of the same or any other provision. No
waiver by Tenant of any breach by Landlord shall be deemed a waiver of any
subsequent breach by Landlord of the same or any other provision. The failure of
Landlord or Tenant to insist at any time upon the strict performance of any
covenant or agreement or to exercise any option, right, power or remedy
contained in this Lease shall not be construed as a waiver or a relinquishment
thereof for the future. Landlord's consent to or approval of any act by Tenant
requiring Landlord's consent or approval shall not be deemed to render
unnecessary the obtaining of Landlord's consent to or approval of any subsequent
act of Tenant. Tenant's consent to or approval of any act by Landlord requiring
Tenant's consent or approval shall not be deemed to render unnecessary the
obtaining of Tenant's consent to or approval of any subsequent act of Landlord.
No act or thing done by Landlord or Landlord's agents during the term of this
Lease shall be deemed an acceptance of a surrender of the Premises, unless done
in writing signed by Landlord, The delivery of the keys to any employee or agent
of Landlord shall not operate as a termination of this Lease or a surrender of
the Premises. The acceptance of any Rent by Landlord following a breach of this
Lease by Tenant shall not constitute a waiver by Landlord of such breach or any
other breach. The payment of Rent by Tenant following a breach of this Lease by
Landlord shall not constitute a waiver by Tenant of any such breach or any other
breach. No waiver by Landlord or Tenant of any provision of this Lease shall be
deemed to have been made unless such waiver is expressly stated in writing
signed by the waiving party. No payment by Tenant or receipt by Landlord of a
lesser amount than the monthly installment of Rent due under this Lease shall be
deemed to be other than on account of the earliest Rent due hereunder, nor shall
any endorsement or statement on any check or any letter accompanying any check
or payment as Rent be deemed an accord and satisfaction and Landlord may accept
such check or payment without prejudice to Landlord's right to recover the
balance of such rent or pursue any other remedy which may be available to
Landlord.

SECTION 15.4 APPLICABLE LAW. This Lease shall be governed by and construed in
accordance with the laws of the State of Texas.

Lease, including, without limitation, the Rules and Regulations. The Building,

                  substantially identical space (as to tenant improvements), of
                  at least the same size insofar as square footage, and at the
                  same monthly rental as set out in the Lease, within the
                  Building upon giving Tenant one hundred twenty (120) days
                  prior written notice of such intention to relocate Tenant,
                  which notice shall set forth the relevant details with respect
                  to such new space in the Building ("Substituted Premises").
                  Effective on the date of such relocation, this lease shall be
                  amended via an amendment to same, to be executed by both
                  Landlord and Tenant, by deleting the description of the
                  original Premises and substituting therefor the description of
                  the Substituted Premises, it being understood and agreed that
                  all other terms and conditions of this Lease shall remain the
                  same. In no event shall the term for the Substituted Premises
                  commence prior to the date when the leasehold improvements in
                  the Substituted Premises are substantially completed by
                  Landlord and/or its contractors, at Landlord's sole cost and
                  expense, on Tenant's behalf. Anything in the foregoing
                  provisions of this Section 15.19 (a) to the contrary
                  notwithstanding, Landlord shall not have the right to relocate
                  the Premises if less than twelve (12) months remain in the
                  Term (except if Tenant shall have exercised its Renewal Option
                  pursuant to Rider 1) or in the Renewal Term, as the case may
                  be.

            (b)   Landlord shall pay for or otherwise reimburse Tenant for all
                  reasonable out-of-pocket expense incurred by Tenant pursuant
                  to the relocation to the Substituted Premises, including, but
                  not limited to, the following: (i) all reasonable costs and
                  expenses, including filing fees and building permits, of
                  reconstructing leasehold improvements in the Substituted
                  Premises to substantially the same condition and level of
                  improvements as existed in the Premises prior to such
                  relocation (i.e. to replicate the Premises); (ii) reasonable
                  moving costs insofar as furniture, fixtures and equipment,
                  filing cabinets and the contents thereof, supplies, telephone
                  and equipment (including disconnect and connect charges),
                  computer equipment, and all other property (including personal
                  property) of Tenant and its employees located in the Premises
                  (using a commercial mover reasonably approved by Tenant or if
                  Tenant elects to do the moving itself, Landlord will reimburse
                  Tenant for the reasonable costs it would have incurred had a
                  commercial mover acceptable to Landlord been hired on a
                  competitive basis; (iii) fiber network, and other
                  communications- and computer-related cabling and connections
                  setup charges; (iv) space planning/interior architecture and
                  engineering fees; (v) reasonable reprinting of stationary,
                  brochures and all other printed materials used by Tenant in
                  its business (on which the address of the Premises appears) of
                  the same quality and quantity as on hand immediately


                                       29
<PAGE>   39

                  prior to Landlord's notice to Tenant of its exercising of this
                  relocation right; and (vi) reasonable costs of
                  change-of-address announcement cards, plus postage costs,
                  directly related to such change-of-address notification to
                  Tenant's clients and vendors.

            (c)   Landlord shall provide substantially the same expansion and
                  first offer rights in generally similar locations and
                  condition (including contiguity), relative to the existing
                  location of the Premises and the expansion and first offer
                  space, on the same terms and conditions as available to Tenant
                  pursuant to Riders 2 and 3; and Tenant's Renewal Option, as
                  set forth in Rider 1, shall remain in full force and effect.
                  Landlord agrees to use reasonable efforts to accommodate the
                  schedule upon which Tenant desires to be relocated so as to
                  avoid an unreasonable interruption of Tenant's operation of
                  its business.

Tenant agree as follows:

1. Plans.

1.1 Construction Plans. Tenant's architect shall prepare and deliver to
Landlord, within fourteen (14) calendar days after execution of the Lease,
construction plans (such construction plans, when approved, and all changes and
amendments thereto agreed to by Landlord and Tenant in writing, are herein
called the `Construction Plans") for all of Tenant's improvements in the
Premises, (all improvements required by the Construction Plans are herein called
"Tenant's Improvements"), including complete detail and finish drawings for
partitions, doors, reflected ceiling, telephone outlets, electrical switches and
outlets and building standard heating, ventilation and air conditioning
equipment and controls. Within five (5) business days after Construction Plans
are delivered to Landlord, Landlord shall approve (which approval shall not be
unreasonably withheld) or disapprove same in writing and if disapproved,
Landlord shall provide Tenant, Tenant's architect and Tenant's engineer specific
reasons for disapproval. Tenant shall promptly revise and redeliver the
Construction Plans for Landlord's review. The foregoing process shall continue
until the Construction Plans are approved by Landlord.

1.2 Changes to Approved Plans. If any re-drawing or re-drafting of the
Construction Plans is necessitated by Tenant's requested changes (all of which
shall be subject to Landlord's approval), the expense of any such re-drawing or
re-drafting required in connection therewith, Landlord's review of such
re-drawing or re-drafting, and the expense of any work and improvements

Review Fee"). The Construction Plans Review Fee shall not exceed $3,840.00.

1.4 Compliance With Disability Acts. Tenant shall cause the construction of
Tenant's Improvements to be completed such that Tenant, the Premises and
Tenant's Improvements (as constructed) will be in compliance with the Disability
Acts. Tenant shall indemnify and hold harmless Landlord from and against, and
reimburse Landlord for and with respect to, any and all claims, liabilities and
expenses (including, without limitation reasonable attorneys' fees and expenses)
incurred by or asserted against Landlord by reason of or in connection with any
violation of the Disability Acts by Tenant and/or Tenant's Improvements or the
Premises not being in compliance with the Disability Acts. The foregoing
indemnity shall not include any claims or expenses arising out of the negligence

<PAGE>   44

Tenant's Improvements (the "Contract Sum"). Any unused Finish Allowance may be

or additional space leased by Tenant during the Term. Tenant acknowledges that
demolition of existing improvements, addition or movement of lights,

one (1) fixture per eighty (80) rentable square foot leased. Tenant may
additionally utilize raised flooring panels and ceiling tile from space outside
of the Premises on the 7th Floor to replace panels/tiles in the Premises and may
utilize all existing improvements in the Premises.

2.2 Excess Costs. If the sum of the Permitted Costs exceeds the Finish
Allowance, then Tenant shall pay all such excess costs.

3. Tenant's Contractor.

      (a)   Notwithstanding anything in this Exhibit C to the contrary, Tenant
            shall contract with Burr Computer Environments, Inc. (the "Tenant's
            Contractor") to construct Tenant's Improvements. Tenant's Contractor
            shall (and its contract shall so provide that it shall):

            (i)   be capable of working in harmony with the Landlord's space
                  planners, architects, engineers, contractors, workmen,
                  mechanics, or other agents or independent contractors in the
                  performance of their work ("Landlord's Agents") and shall
                  comply with such reasonable rules and regulations as may be
                  promulgated by Landlord;

            (ii)  maintain such payment and performance bonds and insurance in
                  force and effect as may be reasonably requested by Landlord or
                  as required by applicable law; and

            (iii) use reasonable efforts to reach an understanding with
                  Landlord's Agents as to the conduct of their work, including

                  temporary utilities, protection of installed materials or-
                  equipment, sanitary facilities, temporary heating, lighting
                  and cooling and access to the Premises (it being understood
                  that the Tenant's Contractor shall arrange with and pay to
                  Landlord's Agents an amount, if any, negotiated by such
                  parties in good faith, with respect to such functions and
                  services).

      (b)   Landlord's sole obligation with respect to construction of the
            Tenant's Improvements shall be to deliver the Premises in its as-is
            condition and contribute the Finish Allowance in accordance with
            Section 2 of this Exhibit C.

      (c)   Tenant's Contractor shall use only subcontractors pre-approved by
            Landlord for all mechanical, electrical, plumbing or fire protection
            work within the Building. Landlord and Tenant agree that Fisk
            Electric shall be the electrical subcontractor.

      (d)   The Construction Plans Review Fee shall be payable to Landlord in
            consideration of Landlord's engineers (CHP & Associates) review of
            Tenant's Construction Plans drawn by Tenant's engineers, and may be
            offset against the Finish Allowance as invoices are received by
            Landlord from CHP & Associates.

Prior to the Commencement Date, Tenant, Tenant's Contractor and other authorized
representatives of Tenant shall have the right to enter upon the Premises for
the purposes of preparing the Premises for construction and for construction of
Tenant's Improvements. Landlord shall not be liable for any injury, loss or
damage to any of Tenant's installations or decorations made prior to the
Commencement Date and not installed by Landlord. Tenant shall indemnify and hold
harmless Landlord and Landlord's Agents from and against and reimburse Landlord
for and with respect to, any and all costs, expenses, claims, liabilities and
causes of action arising out of or in


                                      C-ii
<PAGE>   45

connection with work performed in the Premises by or on behalf of Tenant.
Landlord is not responsible for the function and maintenance of Tenant's
Improvements which are different than Landlord's standard improvements at the
Property or improvements, equipment, cabinets or fixtures not installed by
Landlord. Such entry by Tenant and the Tenant's Contractor pursuant to this
Section 3 shall be deemed to be under all of the terms, covenants, provisions
and conditions of the Lease except the covenant to pay Rent.

4. Delays. Delays in the completion of Construction Plans or completion of
construction of Tenant's Improvements or in obtaining a certificate of
occupancy, if required by the applicable governmental authority, caused by
Tenant, Tenant's Contractor (hereinafter defined) or any person, firm or
corporation employed by Tenant or Tenant's Contractor shall constitute "Tenant
Delay". If the completion of Tenant's Improvements are affected by any Tenant
Delay, then the date Substantial Completion shall be deemed to have occurred
shall be the date the Premises are Substantially Complete, but moved up by one
day for each day of Tenant Delay (by way of example, if the Premises would have
been Substantially Complete on December 1 but for three (3) days of Tenant
Delay, the date of Substantial Completion shall be deemed to have occurred on
November 28). If the completion of Tenant's Improvements are affected by any
delay other than Tenant Delay, then the date Substantial Completion shall be
deemed to have occurred shall be the date the Premises are Substantially
Complete, but moved back (i.e., extended) by one day for each day of such delay
(by way of example, if the Premises would have been Substantially Complete on
December 1 but for three days of delay that are not Tenant Delays, the date of
Substantial Completion shall be deemed to have occurred on December 4).

5. Substantial Completion and Punch List. The terms "Substantial Completion" and
"Substantially Complete," as applicable, shall mean when Tenant's Improvements
are sufficiently completed in accordance with the Construction Plans so that
Tenant can reasonably use the Premises for the Permitted Use (as described in
Item 11 of the Basic Lease Provisions). When Landlord considers Tenant's
Improvements to be Substantially Complete, Landlord will notify Tenant and
within two (2) business days thereafter, Landlord's representative and Tenant's
representative shall conduct a walk-through of the Premises and identify any
necessary touch-up work, repairs and minor completion items as are necessary for
final completion of Tenant's Improvements. Neither Landlord's representative nor
Tenant's representative shall unreasonably withhold his agreement on punch list
items. The Commencement Date set forth in No. 7 of the Basic Lease Provisions is
calculated based on Tenant substantially completing all of Tenant's Improvements
within ten (10) weeks after Landlord's approval of Construction Plans. The
Commencement Date shall be adjusted commensurately with adjustments in
Substantial Completion as set forth in Paragraph 4 above and shall occur on the
date of Substantial Completion whether or not occurring before or after the date
set forth in the Basic Lease Provisions.

6. Temporary Supply of Power. Prior to the Commencement Date and during
construction of Tenant's Improvements, Landlord shall supply temporary power,
HVAC, freight elevator and security during construction, at no additional charge
to Tenant so long as and to the extent that Tenant's usage is reasonable.

7. Special Improvements. Tenant shall have the right to include the following
improvements within Tenant's Improvements, provided the construction and
installation of same are performed by contractors acceptable to Landlord:

      (a)   modification of existing sprinkler system in Premises in a manner
            acceptable to Landlord; and

      (b)   tie in by Tenant into the Building's security system in a manner
            acceptable to Landlord.

8. Landlord's Work. Landlord's sole obligation shall be to construct, at
Landlord's expense, the Landlord's Work, as follows:

            (i)   All Labor, materials, equipment, services and other items
                  necessary to complete the multi-tenant corridor(s) and core
                  finishes, including the elevator lobby on Level 7, in a manner
                  consistent with the other low rise multi-tenant floors in the
                  Building.

            (ii)  All terminations and modifications necessary to existing fire
                  alarm system to accommodate the signals from the tenant system
                  requiring integration with the Building's system.

            (iii) Terminations made at the electrical closet, transformers,
                  risers, conduits, feeders and switchboards necessary to
                  furnish the Premises with electrical power as outlined in

of the Contractor, the cost of such will be negotiated to provide a fair and
equitable arrangement for both parties.

      Tenant is not in default under this Lease, (ii) Tenant then occupies, and
      the Premises then consist of, at least all the original Premises and (iii)

      to or exceeding 12,312 square feet (the "Renewal Space") for one (1)

      and conditions contained in this Lease with the exceptions that (x) this
      Lease shall not be further available for renewal and (y) the rental for
      the Renewal Term shall be the "Market Rental Rate", but in no event will
      the Base Annual Rent for the Renewal Term be less than the Base Annual
      Rent for the last twelve (12) calendar months of the initial term of the
      Lease. If Tenant renews for less than all of the Premises, then the
      configuration of the Renewal Space and the portion of the Premises not
      renewed must be reasonably acceptable to Landlord.

2.    The Market Rental Rate is hereby defined to mean the then prevailing fair
      market rental rate in the Building determined on a "gross" lease basis as
      of the exercise of the respective provision by Tenant, which a willing
      tenant would pay and a willing landlord would accept for space of
      comparable size and condition, taking into consideration all relevant
      factors, including the following:

      (1)   use, location, size and/or floor level(s) of the space in question,
            including view, elevator lobby exposure, etc.;

      (8)   refurbishment and repainting allowances;

      (9)   club membership;

            cooling and heating, plus hourly charges therefor);

      (12)  distinction between "gross" and "net" lease

      (13)  base year or dollar amount for escalation purposes (both operating

      (15)  credit standing and financial stature of the tenant;

      (16)  term of length of lease;

      (17)  the time the particular rental rate under consideration is to become
            effective.

      Landlord will take into consideration the tenant inducements offered in
      the transactions considered by Landlord in determining the Market Rental
      Rate.

3.    If Tenant desires to renew this Lease, Tenant must notify Landlord in
      writing of its intention to renew on or before the date which is at least
      nine (9) months but no more than twelve (12) months prior to the
      Expiration Date. If Tenant timely notifies Landlord of Tenant's exercise
      of its right to renew, this Lease shall be extended as provided herein and
      Landlord and Tenant shall enter into an amendment to this Lease to reflect
      the extension of the term and changes in Rent in accordance with this
      Rider. If Tenant fails to timely notify Landlord in writing of Tenant's
      exercise of its right to renew, this Lease shall end on the Expiration
      Date and Landlord shall have no further obligations or liability
      hereunder.

4.    The Renewal Space shall be delivered to Tenant in an "as is", broom-clean
      condition. Landlord will, however, provide Tenant with a refurbishment
      allowance in an amount not to exceed $5.00 per square foot of Rentable
      Area within the Renewal Space. Such finish allowance shall be used to
      refurbish improvements in the Renewal Space in accordance with plans
      approved by Landlord. The refurbishment allowance shall be taken into
      consideration in determining the Market Rental Rate for the renewal. Any
      unused allowance shall, at Tenant's option, be applied to future leasehold
      improvements or refurbishments in the Renewal Space.

      except for latent defects reported to Landlord within one hundred eighty
      (180) days after delivery, and (ii) within one hundred eighty (180) days
      after Landlord's receipt of the expansion notice from Tenant. The
      Expansion Space will become part of the Premises and be leased to Tenant
      on the same terms as the initial Premises, including Landlord's
      obligations to furnish Tenant with the same finish allowance and
      concessions as provided for the initial Premises, reduced, however, as
      necessary to permit Landlord to fully amortize on a straight line basis
      using a 10% interest factor the finish allowance and concessions over the
      balance of the Term (not including renewal terms). Such finish allowance
      shall be used to refurbish and/or construct improvements in the Expansion
      Space. Within fifteen (15) days after delivering to Landlord the Expansion
      Notice, Landlord and Tenant shall enter into a work letter in
      substantially the form of Exhibit C attached to the Lease (including a
      reasonable Construction Plans Review Fee), it being understood, however,
      that such form shall be modified to reflect appropriate dates, and such
      other changes as are necessary to reflect the agreement of the parties.

C.    Basic Annual Rent for the Expansion Space will be equal to the product of
      the Agreed Rentable Area per square foot rent applicable to the Premises
      (at the time such Basic Annual Rent is calculated) under Item 3 of the
      Basic Lease Provisions, multiplied by the agreed rentable area of the
      Expansion Space. Basic Monthly Rent for the Expansion Space will be equal
      to one-twelfth (1/12th) of the Basic Annual Rent for the Expansion Space.
      Basic Annual Rent and Additional Rent for the Expansion Space shall
      commence on the earlier to occur of (i) the earlier of Substantial
      Completion or ten weeks after Landlord's delivery of the Expansion Space
      to Tenant for construction of improvements (subject to extension for-
      Force Majeure and subject to Landlord's not unreasonably delaying its
      approval of Construction Plans, as provided in the Expansion Space work
      letter) and (ii) the date that Tenant commences use of the applicable
      Expansion Space. Upon such rent commencement date. (w) the Agreed Rentable
      Area of the Premises shall be deemed increased by the agreed rentable area
      for the Expansion Space, (x) the Basic Annual Rent for the Premises shall
      be deemed increased by an amount equal to the Basic Annual Rent for the
      Expansion Space, (y) Basic Monthly Rent for the Premises shall be deemed
      increased to an amount equal to one twelfth (1/12th) of the Basic Annual
      Rent for the Premises (as increased) and (z) Additional Rent for the
      Premises shall be recalculated on the basis of the increased Agreed
      Rentable Area of the Premises.

D.    At such time as Basic Annual Rent commences with respect to any Expansion
      Space, Landlord and Tenant will enter into an amendment to this Lease
      accurately reflecting the addition of the Expansion Space to the Premises,
      (ii) the increase in the Basic Annual Rent and Additional Rent payable
      under this Lease, (iii) the increase in Tenant's Pro Rata Share Percentage
      and (iv) such other amendments as are necessary.

E.    Landlord and Tenant shall promptly execute an Acceptance of Premises
      Memorandum in substantially the form of Exhibit D attached to the Lease.
      If Tenant occupies the Expansion Space without executing the Acceptance of
      Premises Memorandum, Tenant shall be deemed to have accepted the Expansion
      Space for all purposes.

F.    Notwithstanding any provision or inference in this Rider to the contrary,
      the Expansion Option shall expire and be of no further force or effect on
      the earlier of (i) the expiration or earlier termination of the initial
      term of this Lease, (ii) a default by Tenant under this Lease beyond any
      applicable grace period or (iii) the eighteen month anniversary of the
      Commencement Date. In the event Tenant has not exercised the Expansion
      Option on or before the eighteen (18) month anniversary of the
      Commencement Date, the Expansion Space shall revert to being controlled by
      the Right of Opportunity and Offer set forth in Rider 3.

                  TENANT'S RIGHT OF OPPORTUNITY AND FIRST OFFER

      This Rider is attached to and a part of that certain Lease Agreement dated
as of _____________, 1995, executed by and between LASALLE PARTNERS MANAGEMENT
LIMITED (in its capacity as agent for Fannin Street Limited Partnership, a
Delaware limited partnership), and WOLF COMMUNICATIONS COMPANY, a Texas
corporation ("Tenant"). Any capitalized term not defined herein shall have the
meaning assigned to it in the Lease. Landlord and Tenant agree as follows:

A.    Prior to leasing to a third party any of the area described on Schedule A
      attached to this Rider (the "Opportunity Expansion Space"), Landlord shall
      deliver to Tenant a written statement ("Statement") setting forth that the
      entire Opportunity Expansion Space, or named portion thereof, is or will
      be available for direct lease and, in the case of space for which Landlord
      has received an offer to lease from a bona ride prospective tenant (a
      "Third Party Offer"), the name of such tenant. A prospective tenant shall
      be considered bona fide when such prospective tenant has delivered to
      Landlord a counter-proposal to lease the space, at which time Landlord
      shall provide Tenant with the amount of space and the term (including
      renewal terms) contained within the offer. Tenant shall have ten (10)
      business days after receipt of the Statement in the case of a Third Parry
      Offer, or twenty (20) business days otherwise, within which to notify
      Landlord in writing that it desires to lease the entire applicable
      Opportunity Expansion Space set forth in the Statement (each such written
      notice is herein referred to as a "Notice"). Failure by Tenant to notify
      Landlord within such applicable period shall be deemed an election by
      Tenant not to lease the applicable Opportunity Expansion Space and
      Landlord shall have the right to lease such space. If Landlord does not
      lease such Opportunity Expansion Space within the later of (x) one hundred
      twenty (120) days after Landlord's receipt of Tenant's Notice or (y)
      termination of continuous good faith negotiations with the prospective
      tenant, then Landlord will again comply with the provisions of this Rider
      prior to leasing such space to any other third party. Tenant may at any
      time during the Term express interest in any space which is available in
      the Opportunity Expansion Space, and Landlord shall provide a Statement to
      Tenant covering such space. If and when Tenant leases all Opportunity
      Expansion Space (including any Expansion Space which may then be subject
      to this Rider 3), Tenant's rights hereunder shall be extended to all space
      on the 7th floor of the Building which is or may become available for
      lease, subject to (a) prior rights of other tenants in the Building and
      (b) renewals by tenants actually occupying space on the 7th floor whether
      or not such renewals are set forth in their leases.

B.    If Tenant exercises a right to take any Opportunity Expansion Space prior
      to the eighteen (18) month anniversary of the Commencement Date, then such
      Opportunity Expansion Space shall be provided upon the same terms as the
      initial Premises, including Landlord's obligation to furnish the same
      finish allowance and concessions as provided for the initial Premises,
      reduced, however, as necessary to permit Landlord to fully amortize on a
      straight line basis using a 10% interest factor the finish allowance and
      concessions over the balance of the Term (not including any renewal term).
      Thereafter, the Opportunity Expansion Space shall be leased to Tenant upon
      all terms and conditions of this Lease with the following exceptions: (i)
      all Opportunity Expansion Space shall be delivered to Tenant in "as is"
      condition, except for latent defects reported to Landlord within one
      hundred eighty (180) days after delivery; (ii) Basic Annual Rent for the
      Opportunity Expansion Space will be the Market Rental Rate determined as
      set forth in Rider 1; (iii) the Basic Monthly Rent for the agreed rentable
      area of the Opportunity Expansion Space will be equal to one-twelfth
      (1/12th) of the Basic Annual Rent for the Opportunity Expansion Space;
      (iv) the Opportunity Expansion Space will be improved in accordance with
      paragraph D of this Rider; (v) Tenant shall not be entitled to any
      allowances or inducements with respect to the applicable Opportunity
      Expansion Space; and (vi) Basic Annual Rent and Additional Rent with
      respect to the applicable Opportunity Expansion Space shall commence on
      the earlier to Occur of (x) the date that Tenant commences use of the
      applicable Opportunity Expansion Space for any purpose or (y) the earlier
      of Substantial Completion or ten (10) weeks from the date Landlord
      delivers the Opportunity Expansion Space to Tenant for construction of
      leasehold improvements (subject to extension for Force Majeure and
      Landlord not unreasonably delaying its consent


                                    Rider 3-i
<PAGE>   65

      to the Construction Plans, as provided in the Opportunity Expansion Space
      work letter). Upon such rent commencement date, (1) the Agreed Rentable
      Area of the Premises shall be deemed increased by the agreed rentable area
      of the Opportunity Expansion Space, (2) Basic Annual Rent for the Premises
      shall be deemed increased by an amount equal to the Basic Annual Rent for
      the Opportunity Expansion Space, (3) Basic Monthly Rent for the Premises
      shall be deemed increased to an amount equal to one twelfth (1/12th) of
      the Basic Annual Rent for the increased Premises and (4) Additional Rent
      for the Premises shall be recalculated on the basis of the increased
      Agreed Rentable Area of the Premises.

C.    The failure of Tenant to exercise its rights to take Opportunity Expansion
      Space in any given instance shall not prejudice its right to exercise its
      rights to lease with respect to any other space or the same space after
      the appropriate period, should all or any part of such space again become
      available for direct lease or should Landlord again have a bona fide,
      prospective tenant for such space.

D.    Within fifteen (15) days after Landlord's receipt of a Notice, Tenant and
      Landlord will enter into a work letter substantially in the form of
      Exhibit C attached to the Lease (including a reasonable Construction Plans
      Review Fee), provided that such form shall be amended to (i) set forth
      appropriate dates, (ii) amend the finish allowance to be an amount
      calculated in accordance with the other provision of this Rider 3 and
      (iii) provide for such other matters as are necessary to reflect the
      agreements of the parties with respect to the finish out of the applicable
      Opportunity Expansion Space. Pursuant to the work letter, Tenant shall
      construct or cause to be constructed improvements in the applicable
      Opportunity Expansion Space in substantial accordance with construction
      plans agreed to by Landlord and Tenant.

E.    Landlord and Tenant shall promptly upon request of Landlord execute an
      Acceptance of Premises Memorandum in substantially the form of Exhibit D
      attached to the Lease. If Tenant occupies any Opportunity Expansion Space
      without executing the Acceptance of Premises Memorandum, Tenant shall be
      deemed to have accepted such Opportunity Expansion Space for all purposes.

F.    Within fifteen (15) days after Landlord's receipt of a Notice, Landlord
      and Tenant will enter into an amendment to this Lease accurately
      reflecting (i) the addition of the applicable Opportunity Expansion Space
      to the Premises, (ii) the increase in Basic Annual Rent and Additional
      Rent payable under this Lease, (iii) the increase in Tenant's Pro Rata
      Share Percentage and (iv) such other amendments as are necessary.

G.    Notwithstanding any other provision or inference herein to the contrary,
      Tenant's rights and Landlord's obligations under this Rider shall expire
      and be of no further force or effect on the expiration or earlier
      termination of the initial term of this Lease, or during the continuation
      of a default by Tenant under this Lease.

                               FIRST AMENDMENT TO
                            STANDARD LEASE AGREEMENT

      THIS FIRST AMENDMENT TO STANDARD LEASE AGREEMENT (this "Amendment") is
made by and between LASALLE PARTNERS MANAGEMENT LIMITED (in its capacity as
agent for Fannin Street Limited Partnership, a Delaware limited partnership)
("Landlord") and WOLF COMMUNICATIONS COMPANY, a Texas corporation ("Tenant"),
effective this the 18th day of January, 1996 ("Effective Date").

                               W I T N E S S E T H

      WHEREAS, Landlord and Tenant have entered into that certain Standard Lease
Agreement dated June 11, 1995 ("Lease"), for the lease of approximately 12,312
square feet of Agreed Rentable Area (the "Initial Space") located on Floor 7 at
the 1301 Fannin Street Building ("Building") (the land on which the Building is
located is more particularly described in Exhibit "B" attached to the Lease),
all in accordance with the terms, conditions, covenants and obligations
contained in the Lease and the exhibits and riders attached to the Lease; and

      WHEREAS, beginning on the Effective Date, Tenant desires to expand the
Initial Space to include approximately 10,948 square feet of Agreed Rentable
Area located on the 7th Floor of the Building, as shown on the attached Exhibit
"A" (the "Initial Expansion Space").

      NOW, THEREFORE, in and for the premises contained in this Amendment and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, Landlord and Tenant agrees to amend the Lease as follows:

1.    Item 2 of the Basic Lease Provisions is amended to reflect the addition of
      the Initial Expansion Space to the Premises, and the Agreed Rentable Area
      of the Premises beginning on the Effective Date shall read as follows:

      Agreed Rentable Area: 23,260 square feat.

      However, Tenant shall initially occupy only 6570 square feet of the
      Initial Expansion Space. An additional 2189 square feet of Rentable Area
      shall be added on the three (3) month anniversary of the Commencement Date
      for the Initial Expansion Space and an additional 2189 square feet of
      Rentable Area shall be added on the six (6) month anniversary of the
      Commencement Date for the Initial Expansion Space.

2.    Basic Rent for the Initial Expansion Space shall be as follows:

      Lease. The amounts set forth above have been determined based on Tenant's
      staged occupancy of the Initial Expansion Space.

<PAGE>   2

3.    Item 4 of the Basic Lease Provisions is amended to reflect the addition of
      the Initial Expansion Space and shall read as follow:

      Tenant's Pro Rata Share Percentage: 2.966% (the Agreed Rentable Area of
      the Premises divided by the Agreed Rentable Area of the Building,
      expressed in a percentage).

4.    The Initial Expansion Space shall become a part of the leased premises in
      accordance with Rider 3 to the Lease and shall be governed by the
      provisions or the Lease, except for the following matters:

      (a) Tenant has as of the date hereof submitted to Landlord an additional
      Security Deposit in the amount of $209,983.05 as contemplated by, and
      which is to be held and renewed in accordance with, Article 3 of the
      Lease.

      (b) The Lease Cancellation Options contained in Section 13.701 shall apply
      with respect to the entire Premises measured from the original
      Commencement Date. However, the Cancellation Payment shall be increased to
      reflect the increased unamortized leasing costs attributable to the
      Initial Expansion Space: and at the time Tenant executes the Acceptance of
      Premises Memorandum with respect to the Initial Expansion Space, Tenant
      and Landlord agree to replace the existing Exhibit F to the Lease with a
      revised Exhibit F reflecting such increase in the Cancellation Payment.

      (c) The leasehold improvements in the Initial Expansion Space shall be
      constructed in accordance with the Work Letter attached as Exhibit C to
      the Lease, except as follows:

            (i) The time frame for delivery of Construction Plans in Section 1.1
            of Exhibit C shall run from the Effective Date and not the execution
            of the Lease.

            (ii) The Finish Allowance and other concessions for the Initial
            Expansion Space shall be reduced in accordance with Rider 3 to the
            Lease to $14.44 per square foot of Rentable Area within the Initial
            Expansion Space. The foregoing amount is calculated based on a March
            16, 1996 Commencement Date. Such amount shall be adjusted if the
            Commencement Date for the Initial Expansion Space is other than
            March 16, 1996, by using the following formula:

                            STANDARD LEASE AGREEMENT

      THIS SECOND AMENDMENT TO STANDARD LEASE AGREEMENT (this "Amendment") is
made by and between LASALLE PARTNERS MANAGEMENT LIMITED (in its capacity as
agent for Fannin Street Limited Partnership, a Delaware limited partnership)
("Landlord") and WOLF COMMUNICATIONS COMPANY, a Texas corporation ("Tenant"),
effective this the 8th day of August, 1996.

                               W I T N E S S E T H

      WHEREAS, Landlord and Tenant have entered Into that certain Standard Lease
Agreement dated June 11, 1995, as amended by First Amendment to Standard Lease
Agreement dated effective January 18, 1996 (as amended to date, the "Lease"),
for the lease of approximately 23,260 square feet of Agreed Rentable Area
comprised of the Initial Space (12,312 square feet of Agreed Rentable Area) and
the Initial Expansion Space (10,948 square feet of Agreed Rentable Area) located
on Floor 7 of the 1301 Fannin Street Building ("Building") (the land on which
the Building is located is more particularly described in Exhibit "B" attached
to the Lease), all in accordance with the terms, conditions, covenants and
obligations contained in the Lease and the exhibits and riders attached to the
Lease: and

      WHEREAS, beginning on December 1, 1996 (the "Effective Date"), Tenant
desires to expand the Premises to include approximately 36,625 square feet of
Agreed Rentable Area located on the 7th Floor of the Building, as shown on the
attached Exhibit "A" (the "Second Expansion Space").

      NOW, THEREFORE, in and for the premises contained in this Amendment and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, Landlord and Tenant agree to amend the Lease as follows:

1.    Item 2 of the Basic Lease Provisions is amended to reflect the addition of
      the Second Expansion Space to the Premises, and the Agreed Rentable Area
      of the Premises beginning on the Effective Date shall read as follows:

      Agreed Rentable Area: 59,885 square feet.

2.    Basic Rent for the Second Expansion Space shall be as follows:

</TABLE>

      The rental periods referenced above shall be calculated from the Effective
      Date.

3.    Item 4 of the Basic Lease Provisions is amended to reflect the addition of
      the Second Expansion Space and shall read as follows:

      Tenant's Pro Rata Share Percentage: 7.64% (the Agreed Rentable Area of the
      Premises divided by the Agreed Rentable Area of the Building, expressed in
      a percentage).

<PAGE>   2

4.    The Second Expansion Space shall become a part of the Premises in
      accordance with Rider 3 to the Lease and shall be governed by the
      provisions of the Lease, except for the following matters:

      (a) Tenant has as of the date hereof submitted to Landlord an additional
      Security Deposit in the amount of $6l0,264.00 as contemplated by, and
      which is to be held and renewed in accordance with, Article 3 of the
      Lease.

      (b) The Lease Cancellation Option contained in Section 13.701(a) shall be
      terminated and shall no longer be of any force and effect by virtue of
      Tenant having leased all available space on floor 7 of the Building,
      However, for purposes of Section 13.701(b) and 13.702, the Cancellation
      Payment referenced in Section 13.70: shall be increased to reflect the
      increased unamortized leasing costs attributable to the Second Expansion
      Space: and at the time Tenant executes the Acceptance of Premises
      Memorandum with respect to the Second Expansion Space, Tenant and Landlord
      agree to replace the existing Exhibit F to the Lease with a revised
      Exhibit F reflecting such increase in the Cancellation Payment.

      (c) The leasehold improvements in the Second Expansion Space shall be
      constructed in accordance with the Work Letter attached as Exhibit C to
      the Lease, except as follows:

            (i) The time frame for delivery of Construction Plans in Section 1.1
            of Exhibit C shall run from the Effective Date and not the date of
            execution of the Lease.

            (ii) The Finish Allowance and other concessions for the Second
            Expansion Space shall be reduced in accordance with Rider 3 to the
            Lease to $12.56 per square foot of Rentable Area within the Second
            Expansion Space.

            (iii) Landlord shall have no obligation to construct the Landlord's
            Work set forth in Section 8(i), because that work has been completed
            and accepted by Tenant.

5.    Tenant having leased all remaining available space on floor 7 of the
      Building, the Opportunity Expansion Space and Tenant's rights under Rider
      3 to the Lease are modified to cover all space on the 18th floor in
      accordance with the terms of Paragraph A of Rider 3, subject to (a) prior
      rights of other tenants in the Building and (b) renewals by tenants
      actually occupying space on the 18th floor, whether or not such renewals
      are set forth in their leases. Consequently, Schedule A of Rider 3 to the
      Lease is deleted and the term "Opportunity Expansion Space" shall be
      deemed to refer to the entire 18th floor of the Building. As of the
      Effective Date, the only existing lease to which Tenant takes subject is
      the lease with Exxon Corporation.

6.    Section 5.103(c) of the Lease is amended to reflect that Landlord shall
      now furnish UPS power to meet Tenant's loads in an amount not to exceed
      250 KVA: and the total power requirements for all equipment in the
      Premises, whether non-emergency or emergency, shall not exceed 500 KVA.

7.    All capitalized terms used herein and not otherwise defined herein shall
      have the meaning given to such terms in the Lease. Unless specifically
      modified by the foregoing provisions, all of the terms and conditions of
      the Lease shall remain unchanged and in full force and effect, it being
      the intent of the parties to add the Second Expansion Space to the
      Premises.
