                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by and should be read in
conjunction with the more detailed information and financial statements
(including the notes thereto) (the 'Financial Statements') appearing elsewhere
in this Prospectus. Unless otherwise indicated, all information contained in
this Prospectus (i) assumes that the Underwriters' over-allotment option is not
exercised, (ii) has been adjusted to give effect to a decrease in the number of
shares of the Common Stock through a 1-for-2.75 reverse split of the Common
Stock that was effected in December 1997, (iii) assumes the automatic conversion
of the Company's Series A Convertible Participating Preferred Stock (the 'Series
A Preferred Stock') and 10% PIK Series B Convertible Participating Preferred
Stock (the 'Series B Preferred Stock') upon consummation of the Offering and
(iv) reflects the filing of the Restated Certificate of Incorporation of the
Company and the adoption of the Restated By-laws of the Company, both of which
will occur prior to the consummation of the Offering. Certain terms used herein
are defined under 'Glossary'. All references to the Company contained in this
Prospectus, unless otherwise noted, include the Company's predecessor,
Integration Consortium, Inc. ('ICI').
 
                                  THE COMPANY
    
     Icon CMT Corp.'tm' ('Icon' or the 'Company') is an Internet solutions 
provider that offers a comprehensive range of services and products that enable 
corporate customers to implement their Internet, intranet and extranet 
strategies. Icon's mission is to provide end-to-end solutions to its customers 
by facilitating the distribution of the customers' information and applications 
over Icon's communications infrastructure as well as access to such information 
and applications.
     
     In order to provide end-to-end solutions, Icon offers services and products
in three key areas: (i) communications services, including high quality Internet
access and web/server hosting and management, enhanced by the Company's
proprietary technologies; (ii) a range of professional services, including
custom application and website development and design, systems integration and
maintenance and support services; and (iii) product resales, including hardware
and software, which are an integral component of systems design and integration.
Icon differentiates itself by integrating its services and products in order to
provide customized turnkey solutions for the needs of corporate customers.
Unlike many of Icon's competitors who focus on a single service or product, the
Company continuously expands the breadth of its services and its engineering
expertise to optimize its end-to-end solutions.
 
     The emergence of the Internet and the widespread adoption of Internet
Protocol ('IP') as a data transmission standard has resulted in an increasing
number of corporations exploring opportunities to provide IP-based applications
and services within their organization, and to their customers and business
partners. The broad range of business applications, combined with security and
performance requirements, have resulted in demand for high bandwidth networked
systems and for integration and custom application development services.
 
     Revenues generated by the Internet communications services market in the
United States, comprised of access and hosting, are expected to increase from
$1.4 billion in 1996 to $28.1 billion in 2000 according to Forrester Research,
Inc. while the worldwide Internet-related professional services market is
expected to grow from $2.5 billion in 1996 to $13.8 billion in 2000 according to
International Data Corporation. Icon focuses on the corporate market due to its
high growth, low customer turnover and demand for a broad range of higher
value-added Internet services and products.
 
     The Company's communications infrastructure is a key element of its
end-to-end solutions. The Company maintains a nationwide Asynchronous Transfer
Mode ('ATM') backbone that incorporates certain proprietary technologies and is
managed to deploy and distribute information and applications. The Company
manages its network to achieve utilization levels that enable it to operate in a
reliable and high performance manner. The Company controls its network and
provides hosting and management services from its state-of-the-art network
operations center ('NOC'). By controlling its own network, the Company can
develop, select and integrate appropriate technologies that enhance the
 
                                       3

<PAGE>

speed, security, reliability, flexibility and overall performance of its
communications infrastructure, enabling the Company to compete effectively and
meet increasingly demanding customer requirements.
 
     Icon's growth strategy is based on leveraging its capability to provide
end-to-end Internet solutions, which is often a decisive factor in attracting
new customers, as well as generating additional revenue from the existing
customer base. Icon's relationships with several customers, such as The
Associated Press, Bear, Stearns & Co. Inc. ('Bear Stearns') and CBS, Inc.
('CBS') demonstrate how single service or product offerings evolved into broader
solutions opportunities encompassing multiple communications and professional
services and products. To maintain its competitive advantage, Icon intends to:
(i) maintain its reliable and high performance communications infrastructure;
(ii) expand the bandwidth and reach of its network; (iii) expand and integrate
professional services offerings; (iv) continue to build efficient distribution
of services and products through direct and indirect sales channels; and (v)
potentially strengthen its market position through acquisitions.
 
     Icon's distribution strategy depends on a direct sales force, which has
increased from 25 to 33 sales staff during the first nine months of 1997,
dedicated to large accounts with significant revenue generating potential, and
on indirect distribution channels, such as significant relationships with
telecommunications providers like Bell Atlantic Internet Solutions, Inc. ('Bell
Atlantic Internet Solutions') and Fiberlink Communications Corp. ('Fiberlink'),
that extend the Company's reach without substantial costs. Bell Atlantic
Internet Solutions makes Icon's communications services available to requesting
corporate and residential customers and represents a rapidly growing revenue
stream for Icon. In November 1997, Icon entered into a joint venture agreement
with Teleway Corporation ('Teleway') that will extend the reach of the Company's
network into Japan. Recently, Kokusai Denshain Denwa Co. Ltd. announced that it
is in negotiations to acquire Teleway. The Company cannot predict the effect, if
any, such acquisition would have on the joint venture.
 
     Icon serves major corporations, predominantly in the financial services,
media, telecommunications and travel industries, including ABC Radio Network,
ACC Long Distance Corp., Alliance Capital Management LP, The Associated Press,
Barnes and Noble.com Inc., Bear Stearns, Bell Atlantic Internet Solutions,
Bloomberg Financial Markets, CBS, C-NET: The Computer Network, Comedy Central
Network, Daiwa Securities America, Inc., Deutsche Morgan Grenfell, Eastman Kodak
Company, Fiberlink, Galileo International, Merrill Lynch & Co. Inc.,
Metropolitan Life Insurance Co., Moore Capital Management, Inc., Kobra
International (Nicole Miller), Nomura Securities Co. Ltd., Omnipoint
Communications, Swissair, Swissotel, Tudor Investment Company and John Wiley &
Sons, Inc.
 
     ICI, the Company's predecessor, was incorporated in New York in February
1991. Icon was incorporated in Delaware in February 1995, and ICI was merged
with and into Icon in December 1995. The Company's principal executive offices
are located at 1200 Harbor Blvd., Weehawken, New Jersey 07087, and its telephone
number is (201) 601-2000. The Company also maintains an office at 1700 Broadway,
New York, New York 10019. Icon's e-mail address is [email protected], and its
website, which is not a part of this Prospectus, is http://www.icon.com.

LIMITED OPERATING HISTORY; HISTORY OF NEGATIVE CASH FLOW AND OPERATING LOSSES;
GOING CONCERN EXPLANATORY PARAGRAPH IN ACCOUNTANTS' REPORT
 
     The Company was founded in 1991, and consequently there is only a limited
operating history upon which an evaluation of the Company and its prospects can
be based. Although the Company has experienced revenue growth in recent years,
it has not been profitable for the last two years and the Company's recent
growth rate may not be sustainable and may not be indicative of future operating
results. To date, the Company has incurred negative cash flow from operations
and substantial and increasing net losses. Net cash used in operations for the
years ended December 31, 1995 and 1996 and the nine months ended September 30,
1996 and 1997 was $1.3 million, $5.0 million, $4.4 million and $8.6 million,
respectively. Losses from operations for the years ended December 31, 1995 and
1996 and the nine months ended September 30, 1996 and 1997 were $0.6 million,
$8.3 million, $5.8 million and $8.5 million, respectively. The Company had an
accumulated deficit at September 30, 1997 of $17.2 million. The Company expects
to continue to incur significant losses at least through 1998. The report of
independent accountants on the Financial Statements contains an explanatory
paragraph stating that the Financial Statements have been prepared assuming that
the Company will continue as a going concern while expressing substantial doubt
about the Company's ability to do so. The Company's present ability to continue
as a going concern is dependent on its ability to generate sufficient cash flow
to meet its obligations as they become due. The Company's significant operating
losses, expected additional losses and increasing cash and working capital
requirements (see Note 2 to the Financial Statements) raise substantial doubt
about the Company's ability to continue as a going concern.
 
     There can be no assurance that the Company will be successful in attracting
new customers or retaining current customers or continue to increase revenues or
generate profits. There can be no assurance that the Company will ever achieve
profitability. Furthermore, the Company will rely to a great extent on resellers
to market certain of its Internet access services. A substantial portion of such
services is currently resold by a limited number of such resellers. There can be
no assurance that any such resellers will continue to actively market the
Company's services. The Company's prospects must be considered in light of the
risks, expenses and difficulties frequently encountered by companies in their
early stage of development, particularly companies in new and rapidly evolving
markets. To address these risks, the Company must, among other things, respond
to competitive developments, continue to attract, retain and motivate qualified
persons and continue to upgrade its technologies and commercialize services and
products incorporating such technologies. There can be no assurance that the
Company will be successful in addressing such risks.

POTENTIAL FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
     The Company's quarterly operating results have in the past and may in the
future vary significantly depending upon factors such as the timing and
installation of significant orders, which in the past have been, and will in the
future be, delayed from time to time by delays in the provisioning of
telecommunications services and products by subcontractors. Additional factors
contributing to variability of quarterly operating results include the pricing
and mix of services and products sold by the Company, terminations of service,
new service and product introductions by the Company and its competitors, market
acceptance of new and enhanced versions of the Company's services and products,
changes in pricing or marketing policies by its competitors and the Company's
responses thereto, the Company's ability to obtain sufficient supplies of sole
source or limited source components, changes in the Company's communications
infrastructure costs, as a result of demand variation or otherwise, the
lengthening of the Company's sales cycle, access to capital and the timing of
the expansion of the Company's communications infrastructure.
 
CONCENTRATION OF REVENUES
 
     The Company in the past has derived, and, in the future, expects to derive,
a significant portion of its revenue from a relatively limited number of
customers. In 1994, 1995, 1996 and the first nine months of 1997, the Company
derived 25%, 28%, 30% and 49%, respectively, of its revenues from a single
customer, Bear Stearns. In 1994, 1995 and 1996, the Company derived 11%, 15% and
13%, respectively, of its revenues from a second customer, Nomura Securities Co.
Ltd. ('Nomura Securities'). In 1995, the Company derived 10% of its revenues
from a third customer, Merrill Lynch & Co. Inc. ('Merrill Lynch'). In 1996 and
the first nine months of 1997, the Company's top ten customers (in terms of
revenues to the Company) accounted for approximately 66% and 74% of its
revenues, respectively. A substantial majority of sales to Bear Stearns is
attributable to purchase orders issued from time to time and written agreements
with a duration of one year. The Company expects that revenues from Bear Stearns
will decrease as a percentage of revenues in future periods; however revenues
derived from a limited number of current and future customers are expected to
continue to represent a significant portion of the Company's revenues. As a
result, the loss of any of such customers could have a material adverse effect
on the Company's business, financial condition and results of operations. In
addition, there can be no assurance that revenues from customers that have
accounted for significant revenues in past periods, individually or as a group,
will continue, or if continued, will reach or exceed historical levels in any
future period. See 'Business -- Customers'.
 
MANAGEMENT OF GROWTH
 
   
     The Company is currently experiencing rapid growth that could strain the
Company's managerial and other resources. During the 12 months ended September
30, 1997, the number of the Company's employees increased from 170 to 229
full-time employees, and further significant increases are anticipated during
the balance of 1997 and in 1998. The Company's ability to manage its growth
effectively will require it to continue to improve its operational, financial
and other internal systems, and to train, motivate, manage and retain its
current employees and attract new employees. Any inability of the Company's
management to manage growth effectively could have a material adverse effect on
the Company's business, financial condition and results of operations.
    
 
DEPENDENCE UPON SUPPLIERS; SOLE AND LIMITED SOURCES OF SUPPLY
 
     The Company relies on other companies to supply certain key components of
its communications infrastructure, including telecommunications services and
networking equipment that, in the quantities and quality demanded by the
Company, are available only from sole or limited sources. MFS Datanet, Inc.
('MFS') is the primary provider to the Company of data communications facilities
and capacity and leases to the Company physical space for switches, modems and
other equipment. The Company has entered into an agreement with MFS that allows
the Company access to MFS communications facilities, including facilities at any
future sites. Such agreement may be terminated as early as December 1998, is not
exclusive and is subject to early termination under certain circumstances. MFS
 
                                       10
 

<PAGE>
<PAGE>

can enter into similar arrangements with the Company's competitors regarding its
backbone. In 1996, MFS merged with UUNET Technologies, Inc. ('UUNET'), a
competitor of the Company in the area of Internet access. MFS has been acquired
by WorldCom, Inc. ('WorldCom'), which is also a supplier of network services to
Icon. WorldCom has reached an agreement to acquire MCI Communications
Corporation ('MCI'), which is a major provider of Internet backbone services.
The combination of MFS, UUNET, WorldCom and MCI means that one of the Company's
major suppliers is also one of its most formidable competitors in providing
Internet services. The Company is also dependent upon LECs to provide
telecommunications services to the Company and its customers. The Company has
from time to time experienced delays in receiving telecommunications services,
and there can be no assurance that the Company will be able to obtain such
services on the scale and within the time frames required by the Company at an
acceptable cost, or at all. Any failure to obtain such services on a timely
basis at an acceptable cost, including termination or non-renewal of the
Company's relationship with MFS, would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     Certain of the Company's suppliers, including the RBOCs and other LECs,
currently are subject to tariff controls and other price constraints that in the
future may be changed. In addition, regulatory proposals are pending that may
affect the prices charged by the RBOCs and other LECs to their customers,
including the Company. Any such regulatory changes could result in increased
prices for services to the Company, which could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
     The routers, switches and modems used in the Company's communications
infrastructure are currently supplied solely by Cisco Systems Inc. ('Cisco').
The Company purchases these components pursuant to purchase orders placed from
time to time, does not carry significant inventories of these components and has
no guaranteed supply arrangements with Cisco. Cisco sells products to the
Company's competitors and may in the future become a competitor of the Company.
There can be no assurance that Cisco will not enter into exclusive arrangements
with the Company's competitors or that Cisco will continue to sell its products
or components to the Company at commercially reasonable prices, or at all. The
Company from time to time has experienced delays in receiving components from
Cisco. Expansion of communications infrastructures by the Company and others is
placing, and will continue to place, a significant demand on the Company's
suppliers, some of whom have limited resources and production capacity. In
addition, certain of the Company's suppliers, in turn, rely on sole or limited
sources of supply of components included in their products. Failure of the
Company's suppliers to meet such increasing demand may prevent them from
continuing to supply components and products in the quantities and quality and
at the times required by the Company, or at all. The Company's inability to
obtain sufficient quantities of sole or limited source components or to develop
alternative sources, if required, could result in delays and increased costs in
expanding, and overburdening of, the Company's communications infrastructure,
which would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
DEPENDENCE UPON COMMUNICATIONS INFRASTRUCTURE
 
     The Company is dependent on its suppliers' ability to provide necessary
products and components that comply with various Internet and telecommunications
standards and that interoperate with products and components from other vendors.
Any failure of the Company's sole or limited source suppliers to provide
products or components that comply with evolving Internet and telecommunications
standards or that interoperate with other products or components used by the
Company in its communications infrastructure could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     The Company's success will depend upon the capacity, reliability and
security of its communications infrastructure, including the facilities and
capacity leased from suppliers, including MFS. The Company must continue to
expand and adapt its communications infrastructure as the number of users and
the amount of information they wish to transport increases and to meet changing
customer requirements. The expansion and adaptation of the Company's
communications infrastructure will require substantial financial, operational
and management resources. There can be no assurance that the Company will be
able to expand or adapt its communications infrastructure to meet additional
demand or its customers'
 
                                       11
 

<PAGE>
<PAGE>

changing requirements on a timely basis and at a commercially reasonable cost,
or at all. Any failure of the Company to expand its communications
infrastructure on a timely basis or adapt it either to changing customer
requirements or to evolving industry standards could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
DEPENDENCE ON KEY PERSONNEL; ATTRACTION AND RETENTION OF EMPLOYEES
 
     The Company's performance is substantially dependent on the performance of
its executive officers and key employees. In particular, the future success of
the Company is dependent upon the personal efforts of the Company's founders,
Scott A. Baxter, Richard M. Brown and Scott Harmolin, each of whom is a director
and an executive officer of the Company. In the past 12 months, the Company has
hired several executives, including Kenneth J. Hall, Frank C. Cicio, Jr., Robert
J. Thalman, Jr. and Michael J. Gold. There can be no assurance these individuals
will remain with the Company or be successful. The loss of the services of any
of its executive officers or other key employees could have a material adverse
effect on the Company's business, financial condition and results of operations.
The Company does not maintain, nor is it currently contemplating obtaining, 'key
man' life insurance policies on any of its employees. See 'Management'.
 
     The Company's professional services business is labor intensive. The
Company's success will depend in large part upon its ability to attract,
develop, motivate and retain highly skilled technical employees, particularly
project managers and other senior personnel. Qualified project managers are in
great demand and are likely to remain a limited resource for the foreseeable
future. There can be no assurance that the Company will be able to attract and
retain sufficient numbers of highly skilled technical employees and project
managers. The loss of some or all of the Company's project managers and other
senior personnel could have a material adverse effect on the Company, including
its ability to secure and complete projects. While project managers and most
other senior personnel have not entered into employment agreements with the
Company, substantially all the Company's key employees and independent
contractors are parties to nonsolicitation, confidentiality and noncompetition
agreements with the Company. However, no assurance can be given that such
agreements will be honored or that the Company will be able to effectively
protect its rights to its unpatented trade secrets and know-how.
 
COMPETITION
 
     The markets served by the Company are extremely competitive. The Company
expects competition to persist, intensify and increase in the future. Because
there are no substantial barriers to entry, an influx of new market entrants is
expected to continue in response to the growing demand for information and data
communication technology services and products. Most of the Company's current
and potential competitors enjoy a greater market presence and possess
substantially greater technical, financial and marketing resources than the
Company.
 
     COMMUNICATIONS SERVICES
 
     The Company's current and prospective competitors in the Internet
communications services sector generally may be divided into the following five
groups: (i) telecommunications companies, such as AT&T Corp. ('AT&T'), MCI,
Sprint Corp. ('Sprint'), WorldCom, Intermedia Telecommunications Inc.
('Intermedia'), GTE Corporation ('GTE') and LECs; (ii) online services
providers, such as America Online Inc. ('America Online'),The Microsoft Network
('MSN') of Microsoft Corporation and Prodigy Services Company ('Prodigy'); (iii)
Internet service providers ('ISPs'), such as NETCOM On-Line Communications
Services, Inc. ('NETCOM'), PSINet, Inc. ('PSI'), Concentric Network Corporation
('Concentric') and other national and regional providers; (iv) cable modem
connectivity providers such as @Home Networks, Inc. ('@Home'); and (v) data
center providers such as Exodus Communications ('Exodus'). Most of these
competitors have greater market presence, engineering and marketing
capabilities, and financial, technological and personnel resources than those
available to the Company. As a result, they may be able to develop and expand
their communications infrastructures more quickly, adapt more swiftly to new or
emerging technologies and changes in customer
 
                                       12
 

<PAGE>
<PAGE>

requirements, take advantage of acquisitions and other opportunities more
readily, and devote greater resources to the marketing and sale of their
services than can the Company.
 
     Although most of the established online services companies and
telecommunications companies currently offer only limited Internet access
services, many of these companies have announced plans to offer expanded
Internet access services. In addition, the combination of MFS, UUNET, WorldCom
and MCI means that one of the Company's major suppliers is also one of its most
formidable competitors in providing Internet services. In addition, the Company
believes that new competitors, including large computer hardware and software,
media and telecommunications companies, such as the RBOCs, may enter or expand
their presence in the Internet access market, resulting in even greater
competition for the Company.
 
     The Company believes that competitive factors in the communications
services market include market presence, capacity, reliability, security of
communications infrastructure, quality of technical personnel, price, customer
support, new services and enhancements and conformity with industry standards.
There can be no assurance that the Company will have the financial resources,
technical expertise or marketing and support capabilities to compete
successfully in the communications services market. See
'Business -- Competition'.
 
     PROFESSIONAL SERVICES
 
     The professional services market is highly fragmented. The Company
currently encounters competition from mid-sized and regional consulting, design
and systems integration firms such as Cambridge Technology Partners, Inc.
('Cambridge Technology Partners') and Technology Solutions Co. ('Technology
Solutions'), and increasingly competes with large-scale systems integrators,
such as EDS Corp. ('EDS'). The Company's design group also competes with a
variety of interactive design firms including agency.com, Razorfish, USWeb and
CKS Group. The Company believes that the primary competitive factors at work in
this market are price, the ability to fashion and deliver efficient solutions to
customer needs, the quality of service, including project management and ongoing
support and maintenance, and the availability and quality of hardware and
software. Accordingly, the Company competes on the basis of its reputation,
personnel, technical sophistication and ability to provide single-source,
end-to-end solutions, including hardware and software product resales and
communications services. There can be no assurance that the Company will have
the financial resources, personnel, technical expertise or marketing and support
capabilities to continue to compete successfully in the professional services
market. See 'Business -- Competition'.
 
     PRODUCT RESALES
 
     The product resales market in which the Company competes is a high volume,
low margin business with minimal barriers to entry. Product resellers such as
the Company purchase information technology hardware and software products from
OEMs or wholesale distributors and resell the products to its customers. The
Company's current and prospective competitors generally can be divided into
three groups: (i) national and regional VARs, such as EJV Bridge Networks, Bell
Technology Group Ltd. ('Bell Technology') and LANCOM; (ii) national and regional
systems integrators, such as EDS, Sapient, Computer Associates International,
Inc. ('Computer Associates') and The Ergonomics Group; and (iii) hardware
distributors, such as CHS Electronics and ITOCHU Corporation ('ITOCHU'). Growing
product complexity, shorter product life cycles and an increasing number of
information technology products due to the emergence of open systems
architectures and the recognition of certain industry standards have led
resellers to depend on wholesale distributors for more of their product,
marketing and technical support needs. In addition, resellers increasingly rely
on wholesale distributors for inventory management and credit to avoid stocking
large inventories and maintaining credit lines to finance their working capital
needs. The need for resellers to implement high volume/low cost operations is
imperative in light of ongoing price competition and the increasing demand for
value-added services.
 
     The product resales industry is intensely competitive and such competition
is based primarily on price, product availability, speed and accuracy of
delivery, effectiveness of sales and marketing
 
                                       13
 

<PAGE>
<PAGE>

programs, credit availability, ability to tailor specific solutions to customer
needs, quality and breadth of product lines and services, and availability of
technical and product information. Resellers are experiencing additional
pressures from manufacturers that have been successful in selling directly to
the end-user, without the use of resellers. There can be no assurance that
resellers will not lose market share, or that they will not be forced in the
future to reduce prices in response to the actions of competitors and thereby
experience a further reduction in gross margins. As a result of intense price
competition in the product sales industry, reseller margins have continued to
narrow. To the Company, these narrow margins magnify the impact on operating
results of variations in operating costs. Recognizing the challenging dynamics
of the product resales market, the Company has de-emphasized its previous
product resales focus. However, the Company will continue to participate in the
product resales business, which the Company expects will be a source of
significant revenues for the foreseeable future, in order to include OEM
hardware and software in its comprehensive, end-to-end Internet solutions.
 
DEPENDENCE ON DISTRIBUTION AND MARKETING AGREEMENTS
 
     The Company believes that its success in penetrating markets for its
services depends in large part on its ability to maintain and develop additional
relationships with leading technology and communications companies and to
cultivate alternative relationships if distribution channels change. In May
1996, the Company and Bell Atlantic Internet Solutions entered into an
arrangement whereby Bell Atlantic Internet Solutions agreed to provide billing
services in connection with the selection by its customers of the Company's
communications services for both dedicated and switched access. In October 1997,
the Company extended its arrangement by entering into an updated global service
provider ('GSP') agreement with Bell Atlantic Internet Solutions. Also during
1996, the Company entered into agreements with each of Access Graphics, Inc.
('Access Graphics') and Merisel Americas, Inc. ('Merisel'), whereby these
companies agreed to distribute the Company's services and products to the
Company's resellers.
 
     The Company's distribution and marketing agreements, as well as the
arrangement with Bell Atlantic Internet Solutions, are non-exclusive, and many
of the companies with which the Company has such agreements also have similar
agreements with the Company's competitors or potential competitors.
Additionally, the Company's arrangement with Bell Atlantic Internet Solutions is
subject to regulatory scrutiny by federal and state authorities. See
'Business -- Government Regulation'. There can be no assurance that the
Company's distributors and OEM partners, most of which have significantly
greater financial and marketing resources than the Company, will not develop and
market products in competition with the Company in the future, discontinue their
relationships with the Company or form additional competing arrangements with
the Company's competitors. If certain of these agreements were discontinued or
renegotiated in a manner adverse to the Company, it could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
RISK OF SYSTEMS FAILURE
 
     The Company's operations are dependent upon its ability, and the ability of
its suppliers, such as MFS, to protect its communications infrastructure against
damage from fire, earthquakes, power loss, telecommunications failures and
similar events. Despite taking precautions, other Internet access providers have
suffered interruptions as a result of natural disasters and other unanticipated
problems, and in the future such events could cause interruptions in the
services provided by the Company. In addition, failure of the Company's
telecommunications vendors to provide the data communications capacity required
by the Company as a result of operational disruption or for any other reason
could cause interruptions in the services provided by the Company. Any damage or
failure that causes interruptions in the Company's operations could have a
material adverse effect on the Company's business, financial condition and
results of operations.

SECURITY RISKS
 
     Despite the implementation of security measures, any communications
infrastructure is vulnerable to computer viruses and other disruptive problems.
Other Internet access providers have in the past experienced, and the Company
may in the future experience, interruptions in service as a result of the
accidental or intentional actions of Internet users, current and former
employees or others. Unauthorized use could also potentially jeopardize the
security of confidential information stored in the computer systems of the
Company and its customers, which may result in liability of the Company to its
customers and also may deter potential subscribers. Although the Company intends
to continue to implement industry-standard security measures, such measures have
been circumvented in the past, and there can be no assurance that measures
implemented by the Company will not be circumvented in the future. Eliminating
computer viruses and alleviating other security problems may require
interruptions, delays or cessation of service to the Company's customers, all of
which could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
DEPENDENCE ON PROPRIETARY TECHNOLOGIES
 
     The Company's success and ability to compete is dependent in part upon its
proprietary technologies. While the Company relies on patent, trademark,
contract, trade secret and copyright law to protect its proprietary
technologies, it is possible for a third party to copy or otherwise obtain and
use the Company's technologies without authorization, or to develop similar
technologies independently. In addition, effective copyright and trade secret
protection may be unavailable or limited in certain foreign countries. Policing
unauthorized use of the Company's technologies is difficult. Certain of the
Company's software products are currently accessible over the Internet. Such
accessibility to such products increases the likelihood that third parties will
misappropriate them. There can be no assurance that the steps taken by the
Company will prevent misappropriation of its technologies. In addition,
litigation may be necessary in the future to enforce the Company's intellectual
property rights or to protect the Company's trade secrets. Such litigation could
result in substantial costs and diversion of resources and could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     Although the Company does not believe that its services or products
infringe the proprietary rights of any third parties, there can be no assurance
that third parties will not assert such claims against the Company in the future
or that such claims will not be successful. Additionally, the Company could
incur liability from alleged infringements of third party proprietary rights by
the Company's customers. The Company could incur substantial costs and diversion
of management resources with respect to the defense of any claims relating to
proprietary rights, which could materially adversely affect the Company's
business, financial condition and results of operations. Parties making such
claims could secure a judgment awarding substantial damages, as well as
injunctive or other equitable relief that could effectively block the Company's
ability to use or exploit the affected products in the United States or abroad.
Such a judgment could have a material adverse effect on the Company's business,
financial condition and results of operations. See 'Business -- Proprietary
Rights'.
 
     Certain technologies used in the Company's solutions are licensed or leased
from third parties, generally on a non-exclusive basis. The termination of any
of these licenses or leases may have a material adverse effect on the Company's
business, financial condition and results of operations. Replacement of certain
technologies licensed or leased by the Company could be costly and could result
in delays that could have a material adverse effect on the Company's business,
financial condition and results of operations. While it may be necessary or
desirable in the future to obtain other licenses or leases relating to one or
more of the Company's services or products or relating to current or future
technologies, there can be no assurance that the Company will be able to do so,
if at all, on commercially reasonable terms.
 
TECHNOLOGICAL CHANGE; MARKET ACCEPTANCE OF EVOLVING STANDARDS
 
     The markets the Company serves are subject to rapid technological change,
changing customer requirements, frequent new product introductions and evolving
industry standards that may render existing services and products obsolete. As a
result, the Company's position in its existing markets or
 
                                       15
 

<PAGE>
<PAGE>

other markets that it may enter could be eroded rapidly by product advancements
by competitors. The life cycles of the Company's services and products are
difficult to estimate. The Company's future success will depend, in part, upon
its ability to enhance existing services and products and to develop new
services and products on a timely basis. In addition, its services and products
must keep pace with technological developments, conform to evolving industry
standards, particularly client/server and Internet communications and security
protocols, and publishing formats, and address increasingly sophisticated
customer needs. There can be no assurance that the Company will not experience
difficulties that could delay or prevent the successful development,
introduction and marketing of services and products, or that new services and
products and enhancements will meet the requirements of the marketplace and
achieve market acceptance. If the Company is unable to develop and introduce
services and products in a timely manner in response to changing market
conditions or customer requirements, the Company's business, financial condition
and results of operations could be materially and adversely affected.
 
DEPENDENCE UPON GROWTH OF THE INTERNET
 
     The markets that the Company serves with its services and products are in
the early stage of development and dependent on the Internet. Since the markets
are relatively new and the level of competition is increasing, it is difficult
to anticipate the market growth rate and potential saturation. Sales of the
Company's services and products will depend in large part upon a robust industry
and infrastructure for providing commercial Internet access and carrying
Internet traffic and upon increased commercial use of the Internet. The Internet
may not prove to be a viable commercial marketplace or may develop at a slower
rate than would support the Company's continued growth because of inadequate
development of the necessary infrastructure, such as a reliable network, or
timely development of complementary products, such as high speed modems. There
can be no assurance that the infrastructure or complementary products necessary
to make the Internet a viable commercial marketplace will be developed or
available to the Company on reasonable terms. If the necessary infrastructure or
complementary products are not developed or are not made available to the
Company on reasonable terms, or if the Internet and related markets do not
become a significant commercial marketplace, the Company's business, financial
condition and results of operations and will be materially adversely affected.
See 'Business -- Market and Industry Overview'.
 
RISKS ASSOCIATED WITH ACQUISITIONS
 
     As part of its growth strategy, the Company intends to pursue acquisitions
of businesses or customer bases, and investments in, and strategic alliances
with, entities that complement or expand the Company's current operations or
capabilities. The Company is continuously evaluating potential investment
opportunities, but no assurance can be given that the Company will enter into
any understandings, commitments or agreements with respect to any acquisition,
investment, strategic alliance or related effort. Any acquisitions, investments,
strategic alliances or related effort will be accompanied by the risks commonly
encountered in such transactions or efforts. Such risks include, among others,
the failure to identify appropriate candidates, the inability to assimilate
operations and personnel of the respective entities, the potential disruption of
the Company's ongoing business, the inability of management to capitalize on the
opportunities presented by acquisitions, investments, strategic alliances or
related efforts, the failure to successfully incorporate licensed or acquired
technology and rights into the Company's services, the inability to maintain
uniform standards, controls, procedures and policies and the impairment of
relationships with employees and customers as a result of changes in management
or otherwise. Additionally, the Company may incur substantial additional
indebtedness in any acquisition, investment, strategic alliance or related
effort. Such indebtedness could have a material adverse effect on the Company's
business, financial condition and results of operations. There can be no
assurance that the Company would be successful in overcoming these risks or any
other difficulties encountered with respect to such acquisitions, investments,
strategic alliances or related efforts.

GOVERNMENT REGULATION
 
     The Company believes it is not currently subject to direct regulation by
the FCC or any other governmental agency, other than regulations applicable to
businesses generally. To date, the Federal Communications Commission (the 'FCC')
has not actively sought to regulate the provision of Internet access and related
services. Under current law, operators of 'enhanced' services are exempt from
FCC regulation, but operators of 'basic' services are not similarly exempt. The
FCC has not yet addressed whether providing transport services, including
Internet telephony, to customers over an IP-based network is an enhanced
service. A determination by the FCC that providing Internet transport or
telephony services to customers over an IP-based network is subject to
regulation could adversely impact the Company's ability to provide various
existing and planned services, to provide Bell Atlantic Internet Solutions'
customers with the option to purchase the Company's communications and other
services, and could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     In February 1996, the Telecommunications Act of 1996 was signed into law by
the President of the United States. Changes in the regulatory environment
relating to the Internet access industry, including regulatory changes that
directly or indirectly affect the regulatory status of Internet services, affect
telecommunications costs, including the application of access charges to
Internet services, or increase the likelihood or scope of competition from
regional telephone companies or others, could also have a material adverse
effect on the Company's business, financial condition and results of operations.
Due to the increase in Internet use and publicity, it is possible that laws and
regulations may be adopted with respect to the Internet, including with respect
to privacy, pricing and characteristics of services or products. Certain other
legislative initiatives, including those involving taxation of Internet services
and transactions, Internet regulation and universal service contribution
requirements for Internet providers, have also been proposed. The Company cannot
predict the impact, if any, that those or other future laws and regulations or
legal or regulatory changes may have on its business.
 
     In addition, Bell Atlantic Corporation ('Bell Atlantic') has filed a
petition with the FCC seeking relief from various regulations that affect the
deployment of advanced telecommunications services by RBOCs. The petition asks
the FCC to approve Bell Atlantic's (i) provision of high-speed broadband
services without regard to current geographic restrictions, (ii) development of
new services without current pricing, unbundling or separations restrictions and
(iii) sale of new services unrestricted by otherwise applicable price cap and
separate affiliate rules. If the FCC approves the petition, Bell Atlantic or
Bell Atlantic Internet Solutions may be able to undertake many of the functions
that the Company currently performs for Bell Atlantic Internet Solutions'
customers. The FCC has invited public comment on Bell Atlantic's request.
 
     Recently the FCC proposed to eliminate the requirement that RBOCs must file
comparably efficient interconnection plans and obtain approval for those plans
prior to providing new enhanced services. Elimination of this requirement could
lessen certain regulatory burdens currently imposed on Bell Atlantic Internet
Solutions. Furthermore, on December 31, 1997, a Federal District Court Judge
declared several provisions of the Telecommunications Act of 1996 (the
'Telecommunications Act') unconstitutional. If upheld on appeal, this decision
may allow Bell Atlantic to offer certain services, which Bell Atlantic Internet
Solutions and its affiliates have been prohibited from offering under the
Telecommunications Act, without the FCC finding Bell Atlantic to be in
compliance with the network unbundling and other competitive requirements set
out in the Telecommunications Act. The Company currently provides such services
for Bell Atlantic Internet Solutions' customers; and if the decision is upheld
on appeal, Bell Atlantic Internet Solutions or its affiliates may provide such
services directly to their customers.
 
     Bell Atlantic Internet Solutions' relationship with the Company is subject
to review and regulation by state and federal authorities, including the FCC.
Although the Company understands that Bell Atlantic Internet Solutions has
received the requisite approvals to provide service and make the Company's
services available to those of Bell Atlantic Internet Solutions' customers who
request them (which has only included customers in the traditional Bell Atlantic
southern region through the date of this Prospectus), a petition submitted by
MFS in July 1996 for reconsideration of such FCC approvals is currently pending
before the FCC. Additionally, the extension of the Company's service offerings
into
 
                                       17
 

<PAGE>
<PAGE>

the Bell Atlantic northern (NYNEX) region is subject to approvals at the state
and federal levels. There can be no assurance that Bell Atlantic Internet
Solutions will be successful in maintaining or procuring the requisite
regulatory approvals. Failure of Bell Atlantic Internet Solutions to maintain or
prospectively procure such approvals at the federal or state level could
adversely affect the Company's existing agreements with Bell Atlantic Internet
Solutions, and, as a result, the Company's business, financial condition and
results of operations.
 
     Federal and state laws and regulations relating to the liability of online
services companies and Internet access providers for information carried on or
disseminated through their networks is currently unsettled. Several private
lawsuits seeking to impose such liability upon online services companies and
Internet access providers are currently pending. In addition, legislation has
been enacted and new legislation has been proposed that imposes liability for or
prohibits the transmission on the Internet of certain types of information. The
imposition upon the Company and other Internet access providers of potential
liability for information carried on or disseminated through their systems could
require the Company to implement measures to reduce its exposure to such
liability, which may require the expenditure of substantial resources, or to
discontinue certain service or product offerings. The increased attention
focused upon liability issues as a result of these lawsuits and legislative
actions and proposals could impact the growth of Internet use. While the Company
carries professional liability insurance, it may not be adequate to compensate
or may not cover the Company in the event the Company becomes liable for
information carried on or disseminated through its networks. Any costs not
covered by insurance incurred as a result of such liability or asserted
liability could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FINANCING
 
     The Company currently anticipates that the net proceeds from the Offering,
the existing credit facility and funds from operations will be sufficient to
meet its anticipated working capital and capital expenditure requirements at
least through the end of 1998. The Company may need to raise additional funds
through public or private debt or equity financings or by contracting for an
expanded credit facility in order to meet its working capital and capital
expenditure requirements through the end of 1998, to take advantage of
unanticipated opportunities, including more rapid international expansion or
significant acquisitions of complementary businesses or technologies, or to
develop new products or otherwise respond to unanticipated competitive
pressures. Certain covenants under the Company's secured line of credit restrict
the Company, under certain conditions, from, among other things, incurring
additional borrowing or merging with another company. The Company's inability to
borrow additional funds could result in the Company seeking alternative forms of
equity financing, and there can be no assurance that the Company would be
successful in obtaining such financing. If additional funds are raised through
the issuance of equity securities, the percentage ownership of then current
stockholders of the Company may be reduced and such equity securities may have
rights, preferences or privileges senior to those of the holders of the Common
Stock. Any such equity financing may be dilutive to the Company's stockholders.
It is likely that any debt financing or credit facility would restrict the
Company's ability to make acquisitions, borrow from other sources or pay
dividends to stockholders in certain cases. The terms of any such debt or equity
financing could have a material adverse effect on the Company's business,
financial condition and results of operations. The Company does not currently
have any commitments for any additional equity or debt financing, and there can
be no assurance that any financing will be available to the Company or, if
available, that it can be obtained on terms acceptable to the Company. If
adequate funds are not available or are not available on acceptable terms, the
Company may not be able to take advantage of unanticipated opportunities,
develop new technologies or otherwise respond to unanticipated competitive
pressures, or fund its operations. Such inability could have a material adverse
effect on the Company's business, financial condition and results of operations.
See 'Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources'.
 
CONTINUING CONTROL BY CURRENT MANAGEMENT AND EXISTING STOCKHOLDERS
 
     Upon completion of the Offering, Scott A. Baxter, the Company's President,
Chief Executive Officer and Chairman of the Board of Directors, Richard M.
Brown, the Company's Vice President -- Information Technologies and Secretary,
and Scott Harmolin, the Company's Senior Vice President and
 
                                       18
 

<PAGE>
<PAGE>

Chief Technology Officer, each of whom is a director of the Company, will
beneficially own, in the aggregate, approximately 44% of the issued and
outstanding shares of Common Stock. As a result, these stockholders, if they
were to act in concert, would have effective control over the Company and on the
outcome of any matters submitted to the Company's stockholders for approval,
which influence might not be consistent with the interests of other
stockholders. In addition, if they were to act in concert, they may be able to
deter or cause a change in control of the Company and otherwise generally
control the Company's affairs.
 
BROAD DISCRETION IN APPLICATION OF PROCEEDS
 
     A substantial portion of the estimated net proceeds from the Offering will
be allocated to the Company's working capital and general corporate purposes.
Due to the number and variability of factors that will be analyzed before the
Company determines how to use such net proceeds, the Company will have broad
discretion in allocating a significant portion of the net proceeds from the
Offering without any action or approval of the Company's stockholders.
Accordingly, investors will not have the opportunity to evaluate the economic,
financial and other relevant information that will be considered by the Company
in determining the application of such net proceeds. See 'Use of Proceeds'.
 
DILUTION
 
     Purchasers of the Common Stock offered hereby will suffer immediate and
substantial dilution in the amount of $9.28 per share in the net tangible book
value per share of the Common Stock as of September 30, 1997 (assuming that the
initial public offering price of the Common Stock is the mid-point of the range
indicated on the front cover of this Prospectus). See 'Dilution'.
 
BENEFITS OF OFFERING TO CURRENT STOCKHOLDERS
 
     Upon consummation of the Offering, the Company's existing stockholders will
receive substantial benefits, including the creation of a public trading market
for their shares of Common Stock (although the holders of more than 10.7 million
shares of Common Stock have agreed that, for a period of 180 days after the date
of this Prospectus, they will not, among other things, sell such shares without
the prior written consent of Credit Suisse First Boston Corporation), the
corresponding facilitation of such sales in the secondary market and an
immediate increase in net tangible book value of $2.81 per share (based upon the
difference between the adjusted net tangible book value per share at September
30, 1997 and the mid-point of the range indicated on the front cover of this
Prospectus). If the Underwriters exercise their option to purchase 231,000
shares of Common Stock from the Selling Stockholders, such Selling Stockholders
will realize $2.8 million (after deducting underwriting discounts and
commissions and assuming the initial public offering price of the Common Stock
is the mid-point of the range on the cover of this Prospectus).
 
NO DIVIDENDS
 
     The Company has not paid dividends on the Common Stock and does not
anticipate paying any dividends to its stockholders in the foreseeable future.
The declaration and payment of any dividends in the future will be determined at
the discretion of the Board of Directors, and will depend upon the Company's
earnings, capital requirements, financial condition and other relevant factors.
The payment of cash dividends by the Company is prohibited under its revolving
line of credit. In addition, any future bank or other financing may restrict the
Company's ability to declare and pay dividends. See ' -- Future Capital Needs;
Uncertainty of Additional Financing'.
 
NO PRIOR MARKET; POSSIBLE VOLATILITY
 
     Prior to the Offering, there has been no public market for the Common Stock
of the Company. The initial public offering price will be determined by
negotiations among the Company, the Selling Stockholders and the Representatives
of the Underwriters. See 'Underwriting' for a discussion of the factors to be
considered in determining the initial public offering price. There can be no
assurance that an active public market will develop or be sustained after the
Offering or that the market price of the Common Stock will not decline below the
initial public offering price. Future announcements concerning the Company or
its competitors, quarterly variations in operating results, announcements of
technological innovations, the introduction of new services or products or
changes in services or
 
                                       19
 

<PAGE>
<PAGE>

products pricing policies by the Company or its competitors, proprietary rights
or other litigation, changes in earnings estimates by analysts or other factors
could cause the market price of the Common Stock to fluctuate substantially. In
addition, stock prices for many technology companies fluctuate widely for
reasons which may be unrelated to operating results. These fluctuations, as well
as general economic, market and political conditions such as recessions or
military conflicts, may materially and adversely affect the market price of the
Common Stock.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Future sales of shares of Common Stock by existing stockholders pursuant to
Rule 144 ('Rule 144') promulgated under the Securities Act or otherwise could
have an adverse effect on the price of the shares of the Common Stock. Upon
completion of the Offering, the Company will have 15,025,285 shares of Common
Stock outstanding (15,371,785 shares if the over-allotment option is exercised
in full). In addition, the Company has reserved for issuance 2,181,818 shares of
Common Stock upon exercise of options granted under the Company's Amended and
Restated 1995 Stock Option Plan (the '1995 Option Plan') and 948,891 shares of
Common Stock upon exercise of outstanding warrants.
 
     The 3,850,000 shares of Common Stock offered hereby (4,427,500 if the
over-allotment option is exercised in full) will be freely transferable without
restriction or further registration under the Securities Act except for any
shares purchased by an 'affiliate' of the Company within the meaning of Rule
144. The remaining 11,175,285 shares of Common Stock will be 'restricted
securities' as that term is defined in Rule 144, and may only be sold pursuant
to a registration statement under the Securities Act or an applicable exemption
from registration thereunder, including exemptions provided by Rule 144 and Rule
701. No prediction can be made as to the effect that future sales of Common
Stock, or the availability of shares of Common Stock for future sales, will have
on the market price of the Common Stock prevailing from time to time. 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 the Company's ability to raise capital through the future sale of
equity securities. See 'Management,' 'Principal and Selling Stockholders,'
'Shares Eligible for Future Sale' and 'Underwriting'.
 
     In addition, after the Offering, the holders of 4,629,831 shares of Common
Stock and 948,891 warrants will be entitled to certain rights with respect to
registration of such securities and/or securities underlying such securities
under the Securities Act. Registration of such securities under the Securities
Act would result in such securities becoming freely tradeable under the
Securities Act (except for securities purchased by affiliates of the Company)
immediately upon the effectiveness of such registration. See 'Description of
Capital Stock -- Registration Rights of Certain Holders'.
 
ANTI-TAKEOVER PROVISIONS
 
     Certain provisions of the Restated Certificate of Incorporation and
Restated By-laws could make it more difficult for a third party to acquire, and
could discourage a third party from attempting to acquire, control of the
Company. Certain of these provisions allow the Company to issue preferred stock
with rights senior to those of the Common Stock without any further vote or
action by the stockholders and other requirements which could make it more
difficult for stockholders to effect certain corporate actions. Such provisions
could limit the price that certain investors might be willing to pay in the
future for shares of the Common Stock and may have the effect of delaying or
preventing a change in control of the Company. The issuance of preferred stock
also could decrease the amount of earnings and assets available for distribution
to the holders of Common Stock or could adversely affect the rights and powers,
including voting rights, of the holders of the Common Stock. In addition,
certain provisions of the Delaware General Corporation Law prevent certain
stockholders from engaging in business combinations with the Company, subject to
certain exceptions. See 'Description of Capital Stock -- Certain Anti-Takeover
Charter Provisions and Statutory Provisions'.
 
LIMITATIONS ON LIABILITY OF DIRECTORS AND OFFICERS
 
     The Restated Certificate of Incorporation limits the liability of directors
of the Company for breach of fiduciary duty as a director except for (i) breach
of the duty of loyalty to the Company or its stockholders, (ii) acts not in good
faith, involving intentional misconduct or knowing violation of law, (iii)
certain violations of the Delaware General Corporation Law and (iv) transactions
where the
 
                                       20
 

<PAGE>
<PAGE>

director derived an improper benefit. In addition, the Restated Certificate of
Incorporation requires the Company to indemnify directors, officers, employees
and agents of the Company to the fullest extent permitted by such law. The
foregoing provisions may reduce the likelihood of derivative litigation against
directors and officers and may discourage or deter stockholders or management
from suing directors or officers for breaches of their duties to the Company,
even though such an action, if successful, might otherwise benefit the Company
and its stockholders. See 'Description of Capital Stock -- Limitations on
Liability and Indemnification of Officers and Directors'.
 
LIMITATION ON USE OF NET OPERATING LOSS CARRYFORWARDS
 
     Upon consummation of the Offering, there will be an 'ownership change' in
the Company within the meaning of Section 382 of the Internal Revenue Code of
1986, as amended (the 'Code'), which limits the ability of the Company to use
its net operating losses in a given year. Following an 'ownership change,' the
amount of available net operating loss carryforwards and credit equivalents from
periods before the ownership change that may be used by the Company in any tax
year following the change cannot exceed the 'long-term tax-exempt rate' at the
time of the Offering (which rate is 5.27% as of the date of this Prospectus)
multiplied by the value of the Company at the time of the Offering (with certain
adjustments).
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the Offering are estimated to be
approximately $45.7 million ($49.9 million if the over-allotment option is
exercised in full) after deducting underwriting discounts and commissions and
estimated expenses of the Offering payable by the Company.
 
     The Company intends to use approximately $7.5 million of the net proceeds
for upgrade and expansion of its communications infrastructure. The balance of
the net proceeds ($38.2 million) will be used to fund working capital
requirements and for other general corporate purposes, including acquisitions.
Although the Company is continuously evaluating potential investment
opportunities, it does not have, nor can any assurance be given that it will
have, any understanding, commitment or agreement with respect to any
acquisition. If the over-allotment option is exercised in full, additional net
proceeds ($4.2 million) will be added to the Company's working capital.
 
     The amounts of the Company's expected expenditures described herein are
estimates and are subject to change. Unforeseen developments may require that
the Company reallocate a portion of the net proceeds. Pending application of the
proceeds of the Offering, the Company intends to invest the proceeds in
marketable, investment grade, interest-bearing instruments.
 
                                DIVIDEND POLICY
 
     The Company has not paid any cash dividend to stockholders and does not
anticipate paying such dividends in the foreseeable future, as the Company's
Board of Directors intends to retain earnings for use in the development and
continued expansion of the Company's business. The payment of cash dividends by
the Company is prohibited under its revolving line of credit. Any future
determination concerning the payment of dividends will be within the sole
discretion of the Board of Directors and will depend upon the existence of such
restriction, the Company's financial condition, the Company's results of
operations and such other factors as the Board of Directors deems relevant.

     Dilution is the amount by which the initial public offering price paid by
the purchasers of shares of Common Stock in the Offering exceeds the net
tangible book value per share of Common Stock after the Offering. The net
tangible book value per share of Common Stock is determined by subtracting the
total liabilities of the Company from the total book value of the tangible
assets of the Company and dividing the difference by the pro forma number of
shares of Common Stock deemed to be outstanding on the date as of which such
book value is determined.
 
     The net tangible book value of the Common Stock as of September 30, 1997
was $0.91 per share. After giving effect to the sale by the Company of the
3,850,000 shares of Common Stock offered hereby and the application of the net
proceeds therefrom of $45.7 million, the pro forma as adjusted net tangible book
value of the Company at September 30, 1997 would have been $55.9 million, or
$3.72 per share (assuming that the initial public offering price of the Common
Stock is the mid-point of the range indicated on the front cover of this
Prospectus). This represents an immediate increase in the net tangible book
value of $2.81 per share to existing holders of Common Stock and an immediate
dilution of $9.28 per share to new investors. The following table illustrates
this per share dilution (assuming that the initial public offering price of the
Common Stock is the mid-point of the range indicated on the front cover of this
Prospectus):

</TABLE>
 
     If the over-allotment option is exercised in full, the pro forma net
tangible book value per share of Common Stock after giving effect to the
Offering would be $3.91 per share, the increase in the net tangible book value
per share would be $3.00 and the dilution to persons who purchase shares of
Common Stock in the Offering would be $9.09 per share (assuming that the initial
public offering price of the Common Stock is the mid-point of the range
indicated on the front cover of this Prospectus).
 
     The following table summarizes, as of September 30, 1997, the number of
shares of Common Stock purchased from the Company, the total consideration paid
and the average price per share paid by the existing stockholders (including
holders of shares of Series A Preferred Stock and Series B Preferred Stock, all
of which will automatically convert into shares of Common Stock upon
Consummation of the Offering) and new investors, adjusted to give effect to the
sale of the shares of Common Stock offered hereby (assuming that the initial
public offering price of the Common Stock is the mid-point of the range
indicated on the front cover of this Prospectus) and before deducting the
underwriting discounts and commissions and estimated offering expenses payable
by the Company:

     As of September 30, 1997, there were outstanding options to purchase an
aggregate of 1,186,176 shares of Common Stock at a weighted average exercise
price of $6.83 per share and warrants to purchase 948,891 shares of Common Stock
exercisable at a weighted average exercise price of $5.59 per share. Since
September 30, 1997, the Company has granted options to purchase an additional
96,832 shares of Common Stock, each at an exercise price of $13.00. In addition,
options to purchase 31,627 shares of Common Stock, all with an exercise price of
$6.02 per share, were forfeited after September 30, 1997. To the extent these
options or warrants are exercised, there will be further dilution to new
investors. See 'Management -- 1995 Option Plan' and 'Description of Capital

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the Financial
Statements included elsewhere in this Prospectus. This discussion contains
forward-looking statements based on current expectations which involve risks and
uncertainties. Actual results and the timing of certain events may differ
significantly from those projected in such forward-looking statements due to a
number of factors, including those set forth under 'Risk Factors' and elsewhere
in this Prospectus.
 
OVERVIEW
 
     ICI, the Company's predecessor, was incorporated in New York in February
1991. Icon was incorporated in Delaware in February 1995, and ICI was merged
with and into Icon in December 1995. ICI was primarily engaged in the design,
marketing, installation and on-going support of high-end network-based
information management systems. ICI also focused on developing, customizing and
integrating both third-party and proprietary software applications.
 
     In 1995, recognizing the emergence of IP as a data transmission standard,
the Company's management redefined the Company's strategy to provide end-to-end
solutions that enable corporate customers to implement their Internet, intranet
and extranet strategies. The Company's revenues are primarily derived from the
following services and products: (i) a range of professional services, including
custom application and website development and design, systems integration and
maintenance and support services; (ii) communications services including
high-quality Internet access and related services, such as web/server hosting
and management, enhanced by the Company's proprietary technologies; and (iii)
product resales, including hardware and software sold as an integral part of
systems design and integration and as a means to sell integrated communications
and professional services and establish customer relationships.
 
     STATEMENT OF OPERATIONS
 
     The Company provides professional services to its customers to facilitate
the delivery of their information and applications over Icon's communications
infrastructure, including development, design and integration services and
maintenance and support services. Revenues from development, design and systems
integration contracts are recognized on a percentage-of-completion basis.
Maintenance and support services are typically provided in accordance with
annual agreements that are renewable at the discretion of the customer and
subject to change annually. Maintenance and support revenues are recognized
ratably over the term of the respective agreement.
 
     Revenues from communications services are generated by providing Internet
access and other related communications services, such as web/server hosting and
management. Communications services are generally provided based on one-year or
multi-year service agreements, which are renewable at the discretion of the
customer. Communications services revenues are recognized ratably over the term
of the respective service agreement.
 
     As a result of the Company's implementation of its end-to-end solutions
strategy, services revenues (which incorporate professional, communications and
media services) have increased on a yearly basis as a percentage of total
revenue. For the years ended December 31, 1994, 1995 and 1996, services revenues
comprised 10.1%, 18.3% and 22.0% of total net revenues, respectively. For the
nine months ended September 30, 1997 services revenues were 52.8% of total net
revenues as compared to 18.2% for the similar period in 1996. The increase in
services revenues as a percentage of total net revenues is expected to continue
to increase in the future. Historically, the Company generated limited media
revenues from selling advertisement space on its three new-media properties,
Word'tm', Charged'tm' and SportsFan Online. The Company is not actively
marketing these properties and does not expect to expand this business. The
Company has experienced and expects to continue to experience operating losses
in connection with the ongoing operation of its media properties. The Company
has recently commenced efforts to identify potential strategic partners to
assist in the exploitation of these properties. While it is the Company's
intention and desire to continue to design, produce and distribute such
properties, it does not intend to continue its role as a publisher of
proprietary properties. The
 
                                       25
 

<PAGE>
<PAGE>

Company's media properties have historically operated at a loss, but have
nevertheless served a valuable marketing function, helping the Company attract
employees and win new business.
 
     Historically the Company has experienced relatively stable gross margins on
product sales. For the years ended December 31, 1994, 1995 and 1996 gross
margins on product sales were 17.3%, 17.6% and 17.3%, respectively, and for the
nine months ended September 30, 1996 and 1997 were 17.6% and 18.4%,
respectively. Over the same periods gross margins on services have fluctuated as
cost of revenues, particularly on communications services, have increased in
advance of revenue growth for such services. The Company anticipates that in the
future services will provide greater opportunities for increased gross margins.
 
     The Company generates products revenues through the reselling of computer
and networking hardware and software, including network servers, routers,
firewall software, and database management software. Products revenues are
recognized upon shipment.
 
     Professional services cost of revenues consists of the labor and overhead
costs for the personnel performing the service including the cost of project
management, quality control and project review. Cost of communications services
revenues consists primarily of the cost to maintain and operate the Company's
communications infrastructure and customers' hosted web servers, access charges
from LECs and network and related communications facilities costs, depreciation
of network equipment and rental expenses for equipment pursuant to operating
leases. The Company expects its services revenues to continue to increase in
dollar amount, while declining as a percentage of services revenue as the
Company expands its customer base and more fully utilizes its communications
infrastructure. Cost of revenues for products consists primarily of the
Company's acquisition cost of computer and networking hardware and software that
is purchased from the manufacturers' distributors.
 
     General and administrative expenses consist primarily of personnel expense
and professional fees, as well as rent and operating costs of the Company's
facilities. The Company expects general and administrative expenses to increase
in dollar amount, reflecting the continued growth of its operations and the
costs associated with being a publicly held entity, but to decrease in future
years as a percentage of total net revenues.
 
     Selling and marketing expenses consist primarily of personnel expenses,
including salary, benefits, commissions, overhead costs and the cost of
marketing programs, such as advertising, trade shows and public relations. The
Company expects selling and marketing expenses to continue to increase in dollar
amount in future years as the Company's business grows and as it increases its
presence at trade shows, increases the size of its sales force and develops
additional materials to reach a larger audience. The Company expects marketing
expenses to decrease as a percentage of total net revenues due to the fact that
initial marketing expenses, such as development and preparation of collateral
materials, were incurred upon the expansion of business lines.
 
     Research and development expenses consist primarily of personnel and
related costs associated with the development of the Company's technologies. The
Company expects its research and development spending to continue to grow and to
increase modestly as a percentage of total operating expenses in future years.
The Company's expectations of significant revenue growth are not dependent,
however, upon the success of ongoing future research and development activities.
 
     OTHER
 
     In order to provide nationwide communications services including Internet
access, the Company entered into a three-year agreement in June 1995 with MFS to
access MFS' nationwide communications facilities and related communications
products and services. The terms of the agreement provide for the Company to pay
MFS primarily based on the average bandwidth of the Company's traffic
transmitted over MFS' communications facilities. The Company believes that the
usage-based pricing plan established in the agreement has allowed, and will
continue to allow, the Company to grow communications services revenues without
incurring the full fixed costs typically associated with building a nationwide
network and Internet access. The Company also believes that as the utilization
of its network increases the Company may elect to lease and install its own
dedicated high speed connections between nodes and may rely less on MFS'
communications facilities for data transport.

     The Company, which had been profitable prior to 1995, has incurred net
losses and negative cash flow from operations since transitioning its strategy
to provide end-to-end Internet solutions and expects to continue to operate at a
loss and experience negative cash flow at least through 1998. The Company's
attainment of profitability and positive cash flow is dependent upon its ability
to substantially grow its revenue base and achieve related operating
efficiencies.
 
     The Company will continue to focus on growing its professional services and
communications services businesses, which could require it to significantly
increase its expenses for personnel and marketing.
 
     The Company serves major customers in information intensive industries,
such as financial services, telecommunications, media and travel. Revenues
attributable to Bear Stearns comprised 24%, 28% and 30% of the Company's total
net revenues in 1994, 1995 and 1996, respectively, and 49% for the nine months
ended September 30, 1997. Revenues attributable to Nomura Securities comprised
11%, 15% and 13% of the Company's total net revenues in 1994, 1995 and 1996,
respectively, and 3% for the nine months ended September 30, 1997. Revenues
attributable to Merrill Lynch comprised 10% of the Company's total net revenues
in 1995. No other customers represented over 10% of the Company's total net
revenues in the same time periods. Management expects revenue concentration to
decline as the Company grows its services revenues.
 
     Historically, the Company has marketed and sold its services and products
through its direct sales force and through indirect channels. In May 1996, the
Company entered into an arrangement with Bell Atlantic Internet Solutions
whereby Bell Atlantic Internet Solutions agreed to provide billing services in
connection with the offering of the Company's communications services to
requesting Bell Atlantic Internet Solutions customers for both dedicated and
switched access, including residential customers. Revenues from customers
acquired through Bell Atlantic Internet Solutions were a significant portion of
communications services revenues in the nine months ended September 30, 1997.
The Company believes that revenues from this arrangement will continue to grow
and that this relationship will represent a significant element of Icon's
distribution strategy in Bell Atlantic Internet Solutions' region. In October
1997, the Company extended its arrangement by entering into an updated GSP
agreement with Bell Atlantic Internet Solutions to continue to make its services
available in the traditional Bell Atlantic southern region for switched and
dedicated services and to expand the Company's reach with respect to dedicated
services into the Bell Atlantic northern region (previously NYNEX) through
October 1999. The Company currently plans that it will make its services
available to requesting Bell Atlantic Internet Solutions business customers in
the northern region during the first half of 1998. See 'Business -- Sales and
Marketing'. The Company also has agreements with Access Graphics, Fiberlink,
Merisel and other resellers to resell the Company's communications services.
 
     The Company has incurred losses in 1995, 1996 and the nine months ended
September 30, 1997 that have generated net operating loss carryforwards of
approximately $15.3 million at September 30, 1997 for federal and state income
tax purposes. These carryforwards are available to offset future taxable income
and expire in 2011 through 2012 for federal income tax purposes. See 'Risk
Factors -- Limitations on Use of Net Operating Loss Carryforwards'.

     NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED
SEPTEMBER 30, 1996
 
     Revenues. Total net revenues were $30.3 million for the nine months ended
September 30, 1997, a $3.0 million increase over total net revenues of $27.3
million for the nine months ended September 30, 1996.
 
     Professional services revenues were $12.0 million and $3.9 million for the
nine months ended September 30, 1997 and 1996, respectively, representing an
increase of 205%. This increase was attributable to the growing demand for
professional services in its existing customer base and the acquisition of
several new customers, a high renewal rate of existing maintenance contracts, an
increased number of systems engineers available to perform these services and a
higher utilization and average billing rate per systems engineer.
 
     Communications services revenues were $3.9 million and $0.7 million for the
nine months ended September 30, 1997 and 1996, respectively, representing an
increase of over 470%. This increase is primarily attributable to the
acquisition of new customers and the arrangement with Bell Atlantic Internet
Solutions under which the Company began providing service in the third quarter
of 1996. Revenues derived from the Bell Atlantic Internet Solutions arrangement
were a significant component of communications revenues in the nine months ended
September 30, 1997.
 
     Products revenues were $14.3 million and $22.3 million for the nine months
ended September 30, 1997 and 1996, respectively. This decrease was due primarily
to the transition of the Company's focus from its historical role as a VAR to
providing IP network-related services.
 
     Cost of revenues. Total cost of revenues were $23.2 million and $22.7
million for the nine months ended September 30, 1997 and 1996, respectively,
representing 76.6% and 83.2% of total net revenues,
 
                                       28

respectively. The overall margin improvement was primarily attributable to the
continued successful implementation of the Company's strategy to sell
higher-margin professional services.
 
     Services cost of revenues were approximately $11.5 million and $4.3 million
for the nine months ended September 30, 1997 and 1996, respectively. This growth
is primarily attributable to the hiring of 23 additional professional services
personnel and the continued expansion of the Company's communications
infrastructure. As a percentage of services revenues, such costs declined to
72.0% in the nine months ended September 30, 1997 from 87.1% in the year earlier
period, mostly due to increased utilization of systems engineers.
 
     Products cost of revenues were $11.7 million and $18.4 million for the nine
months ended September 30, 1997 and 1996, respectively, representing 81.6% and
82.4% of products revenues for the nine months ended September 30, 1997 and
1996, respectively. The slight decrease in margin was due primarily to a change
in the mix of resold products.
 
     General and administrative. General and administrative expenses were $7.6
million and $5.0 million for the nine months ended September 30, 1997 and 1996,
respectively. This higher level of expenses reflects an increase in personnel
and professional fees necessary to manage the financial, legal and
administrative aspects of the business as well as rent and operating costs of
the Company's facilities. General and administrative expenses as a percentage of
total net revenues increased to 25.0% for the nine months ended September 30,
1997 from 18.5% in the year earlier period due to the expansion of the Company's
administrative infrastructure necessary to manage the rapid growth of the
Company's services business.
 
     Selling and marketing. Selling and marketing expenses were $6.5 million and
$4.4 million for the nine months ended September 30, 1997 and 1996,
respectively. The 49.1% increase in 1997 reflects increased spending including
the development of new marketing materials. Selling and marketing expenses as a
percentage of total net revenues increased to 21.6% for the nine months ended
September 30, 1997 from 16.1% in the year earlier period as a result of the
increased marketing effort.
 
     Research and development. Research and development expenses were $0.9
million and $0.6 million for the nine months ended September 30, 1997 and 1996,
respectively. This higher level of expense reflects an overall increase in the
number of personnel required to develop new technologies that enhance the
performance and reliability of the Company's network. Research and development
expenses as a percentage of total net revenues increased to 3.0% for the nine
months ended September 30, 1997 from 2.2% in the year earlier period as a result
of the Company's increased efforts to deliver enhanced communications services
to its customers.
 
     YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     Revenues. Total net revenues were $38.1 million in 1996, an $11.9 million
increase over total net revenues of $26.2 million in 1995.
 
     Professional services revenues were $6.6 million and $4.4 million in 1996
and 1995, respectively, representing an increase of 49.4%. This increase was
attributable to the growing demand for professional services in the Company's
existing customer base and the acquisition of several new customers, a high
renewal rate of existing maintenance contracts, the increased number of systems
engineers available to perform these services and a higher utilization and
average billing rate per systems engineer.
 
     Communications services revenues increased to $1.3 million in 1996 from
$0.2 million in 1995, representing an increase of 570%. This increase is
primarily attributable to the acquisition of new customers, the rollout of the
Bell Atlantic Internet Solutions arrangement in the second half of 1996 and the
continued cross-selling of communications services to the Company's existing
professional services and products customers.
 
     Products revenues were $29.7 million and $21.4 million in 1996 and 1995,
respectively, representing an increase of 38.8%. This increase was due primarily
to hardware and software resales related to large scale systems integration
projects for customers in the financial services industry.

million in 1996 and 1995, respectively, representing 82.5% and 77.3% of total
net revenues, respectively. This decline in margin is primarily attributable to
the expansion of the Company's network, resulting in significant fixed costs
with minimal communications services revenues.
 
     Services cost of revenues were $6.8 million and $2.5 million in 1996 and
1995, respectively. This growth is primarily attributable to the hiring of
professional services personnel, expansion of the Company's communications
infrastructure and costs associated with the Company's media properties. Such

from 9.3% in the year earlier period due to expansion of the Company's
administrative infrastructure necessary to manage the rapid growth of the
Company's services business.
 
     Selling and marketing. Selling and marketing expenses were $6.5 million and
$3.5 million in 1996 and 1995, respectively. The 88.5% increase in 1996 reflects
an increase in sales commissions resulting from increased services and products
revenues combined with increased marketing and promotional activities, including
advertising and trade shows. Selling and marketing expenses as a percentage of
total net revenues increased to 17.1% in 1996 from 13.2% in 1995 as a result of
the higher sales commissions and increased marketing and promotional activities.
 
     Research and development. Research and development expenses were $1.0
million and $0.4 million in 1996 and 1995, respectively. This higher level of

million in 1995 and 1994, respectively, representing 77.3% and 78.4% of total
net revenues, respectively.
 
     Services cost of revenues were $2.6 million and $0.8 million in 1995 and
1994, respectively. This growth was primarily attributable to the hiring of
professional services personnel and the initial investment in the communications
network. As a percentage of services revenues, such costs increased to 54.2% in
1995 from 39.6% in 1994, reflecting a lower utilization of professional services

and $0.5 million in 1995 and 1994, respectively.
 
QUARTERLY RESULTS OF OPERATIONS
 
     The Company's quarterly operating results have in the past and may in the
future vary significantly depending upon factors such as the timing and
installation of significant orders, which in the past have been and will in the
future be, delayed from time to time by delays in the provisioning of
telecommunications services and products by subcontractors. Additional factors
contributing to variability of quarterly operating results include the pricing
and mix of products and services sold by the Company, terminations of service,
new services and products introductions by the Company and its competitors,
market acceptance of new and enhanced versions of the Company's services and
products, changes in pricing or marketing policies by its competitors and the
Company's responses thereto, the Company's ability to obtain sufficient supplies
of sole source or limited source components, changes in the Company's
communications infrastructure costs, as a result of demand variation or
otherwise, the lengthening of the Company's sales cycle, access to capital and
the timing of the expansion of the Company's communications infrastructure.
 
     The following tables set forth the statement of operations data for each of
the seven quarters through September 30, 1997, as well as such operations data

$8.6 million and $4.4 million, respectively. Net cash used in investing
activities for the nine months ended September 30, 1997 and 1996 was
approximately $2.7 million and $3.0 million, respectively. For the nine months
ended September 30, 1997 and 1996, cash of approximately $15.3 million and $7.0
million, respectively, was provided by financing activities. Cash provided by
financing activities in the nine months ended September 30, 1997 includes
approximately $16.5 million in net proceeds from the issuance of the Series B
Preferred Stock.
 
     Net cash used in operating activities for the years ended December 31, 1995
and 1996 was $1.3 million and $5.0 million, respectively. Net cash flow provided
by financing activities was $2.9 million and $8.6 million for 1995 and 1996,
respectively.
 
     As of September 30, 1997, the Company's operating lease obligations were
projected to be $1.7 million, $1.4 million, and $1.1 million for 1998, 1999 and
2000, respectively.
 
     On August 13, 1996, the Company obtained a secured line of credit with The
CIT Group/Business Credit, Inc. ('CIT') for $10.0 million which expires on
August 13, 1998. Borrowings under this line are secured by substantially all of
the assets of the Company and are limited to a specified percentage of
qualifying accounts receivable less outstanding obligations of the Company owed
to CIT including outstanding letters of credit. Under this secured line of
credit, the Company may not pay cash dividends, pledge any of its assets to
third parties, borrow money from third parties, lend money to third parties or
merge or consolidate with third parties without CIT's prior written consent. At
December 31, 1996, borrowings under this line amounted to $2.2 million, and no
amounts were outstanding at September 30, 1997. The Company does not currently
expect that it will be necessary to use the secured line of credit to meet its
working capital and capital expenditure requirements through the end of 1998.
Interest is payable monthly at an annual rate equal to the prime rate plus one
percent. Following a change in the prime rate, the rate adjusts on the first of
the month following any change. Interest expense amounted to $0.1 million and
$0.4 million for the year ended December 31, 1996 and the nine-month period
ended September 30, 1997, respectively. As of September 30, 1997, there was $2.5
million available under the line.
 
     As of September 30, 1997, trade payables to a vendor in the amount of $2.6
million were secured by a lien on substantially all of the Company's assets.
 
     The Company has made capital investments in its network, NOC and other
capital assets totaling $1.0 million and $3.7 million in 1995 and 1996,
respectively, and $2.7 million in the nine months ended September 30, 1997. The
Company expects to make additional capital investments to expand and enhance its
operations of $2.5 million during the last quarter of 1997, and $4.9 million in
1998. The foregoing expectation with respect to capital investment is a
forward-looking statement that involves risks and uncertainties and the actual
amount of capital investment could vary materially as a result of a number of
factors, including those described in 'Risk Factors -- Future Capital Needs;
Uncertainty of Additional Financing'.
 
     Since the Company expects to incur additional operating losses, the Company
intends to utilize the net proceeds from the Offering to meet its short term
capital requirements. The Company believes that proceeds from the Offering will
be sufficient to meet its anticipated cash needs for working capital and for the
acquisition of capital equipment through the end of 1998. However, there can be
no assurance that the Company will not require additional financing within this
time frame. The Company's forecast of the period of time through which its
financial resources will be adequate to support its operations is a
forward-looking statement that involves risks and uncertainties, and actual
results could vary. The Company may be required to raise additional funds
through public or private financing, strategic relationships or other
arrangements. There can be no assurance that such additional financing, if
needed, will be available on terms attractive to the Company, or at all.
Furthermore, any additional equity financing may be dilutive to stockholders,
and debt financing, if available, may involve restrictive covenants. Strategic
arrangements, if necessary to raise additional funds, may require the Company to
relinquish its rights to certain of its technologies. See 'Risk
Factors -- Future Capital Needs; Uncertainty of Additional Financing'.

   
RECENTLY ISSUED ACCOUNTING STANDARD
    
 
 
     In June 1997, FASB issued Financial Accounting Standards No. 130,
'Reporting Comprehensive Income' ('FAS 130'), which requires the presentation of
components of comprehensive income in a 
 
                                       33
 

<PAGE>
<PAGE>

company's financial statements for the reporting periods begining subsequent to
December 15, 1997. Comprehensive income is defined as the change in a company's
equity during a financial reporting period from transactions and other
circumstances from nonowner sources (including cumulative translation
adjustments, minimum pension liabilities and unrealized gains/losses on
available for sale securities). The adoption of FAS 130 is not expected to have
a material impact on the Company's financial statements.

GENERAL
 
     Icon is an Internet solutions provider that offers a comprehensive range of
services and products that enable corporate customers to implement their
Internet, intranet and extranet strategies. Icon's mission is to provide
end-to-end solutions to its customers by facilitating the distribution of the
customers' information and applications over Icon's communications
infrastructure as well as access to such information and applications. In order
to provide end-to-end solutions, Icon integrates services and products in three
key areas: (i) communications services, including high quality Internet access
and web/server hosting and management, enhanced by the Company's proprietary
technologies; (ii) a range of professional services, including custom
application and website development and design, systems integration and
maintenance and support services; and (iii) product resales, including hardware
and software, which are an integral component of systems design and integration
and serve as a means of establishing customer relationships. Icon differentiates
itself by integrating its services and products to provide customized turnkey
solutions for the needs of corporate customers. Icon's customers include major
corporations in the financial services, telecommunications, travel and media
industries, such as ABC Radio Network Inc. ('ABC Radio'), The Associated Press,
Bear Stearns, Bell Atlantic Internet Solutions, CBS, Galileo International
('Galileo'), Swissair and Swissotel.
 
MARKET AND INDUSTRY OVERVIEW
 
     The emergence of the Internet and the widespread adoption of IP as a data
transmission standard in the 1990s, combined with deregulation of the
telecommunications industry and advances in telecommunications technology, have
significantly increased the demand for providing data communications
applications and services over public networks. At the same time, growth in
client/server and distributed computing, multimedia personal computers and
online computing services and the proliferation of networking technologies have
resulted in a large and growing group of end-users who are accustomed to using
networked computers for a variety of purposes, including electronic mail,
electronic file transfers, online computing and electronic financial
transactions. These trends have increasingly led businesses to explore
opportunities to provide IP-based applications and services internally within
their organizations via intranets, externally to selected customers and business
partners via extranets and to the general public via the Internet.
 
     The ubiquitous nature and relatively low cost of the Internet have resulted
in its widespread usage for certain applications, most notably web browsing and
electronic mail. Use of the Internet for mission-critical business applications
is increasing even with the limited security and unreliable performance inherent
in the structure and management of the Internet, as well as the difficulties of
integrating web gateways and IP-based networks with applications traditionally
run on legacy systems. Additionally, emerging applications such as IP-based
audio and video applications and certain multimedia applications require a
communications infrastructure that has high performance characteristics,
including low latency (response time) and high throughput. These factors have
resulted in demand from an increasing number of businesses for high bandwidth
Internet access, secure networked systems, technology-related products and
integration and custom application development services. Revenues generated by
the Internet communications services market in the United States, comprised of
access and hosting, are expected to increase from $1.4 billion in 1996 to $28.1
billion in 2000 according to Forrester Research, Inc., while the worldwide
Internet-related professional services market is expected to grow from $2.5
billion in 1996 to $13.8 billion in 2000 according to International Data
Corporation.
 
     As the amount of information transmitted over the Internet has grown and
the speed and complexity of networks has increased, IP-based services and
products have become increasingly intertwined. Corporate customers have not only
come to rely on IP-based networks for distributing mission-critical information
and applications to end-users but have become dependent on the technical
services that enable access and distribution of this information, resulting in
an increasing number of outside vendors offering services to corporate
customers. However, given the growth in complexity and expenditures related to
implementation of Internet, intranet and extranet strategies, the Company
believes that customers are increasingly seeking a single-source provider.

STRATEGY
 
     Icon is an Internet solutions provider that offers a comprehensive range of
services and products that enable corporate customers to implement their
Internet, intranet and extranet strategies. Icon's mission is to provide
end-to-end solutions to its customers by facilitating the distribution of
customers' information and applications over Icon's communications
infrastructure as well as access to such information and applications. Unlike
many of its competitors who focus on a single service or product, the Company
continuously expands the breadth of its services and its engineering expertise
to provide customized turnkey solutions to meet the increasingly demanding
requirements of corporate customers. In order to provide end-to-end solutions,
Icon offers communications and professional services, as well as product resales
capabilities. The key strategic initiatives of the Company are to:
 
      Leverage Capability to Provide End-to-End Internet Solutions. Icon's
      ability to provide end-to-end solutions is often a decisive factor in
      attracting and retaining customers and contributes to generating
      additional business from its existing customer base. While some of the
      Company's customers are initially attracted to Icon's end-to-end
      solutions, others seek a specific service or product. The Company has
      historically succeeded in migrating many of such customers to become users
      of the Company's additional services and products. Icon's relationships
      with several customers, such as The Associated Press, Bear Stearns, CBS
      and Galileo, began with a single offering and evolved into an end-to-end
      solution encompassing multiple communications and professional services.
      The Company's strategy is to expand the number of customers who demand
      end-to-end solutions and to become an integral component of its customers'
      information technology infrastructure.
 
      Maintain Reliable and High Performance Communications Infrastructure. The
      Company maintains a nationwide communications infrastructure that
      incorporates proprietary technologies and is managed to deploy and
      distribute information and applications. The Company manages its network
      to achieve utilization levels that enable it to operate in a reliable and
      high performance manner. Icon controls its network and provides hosting
      and management services from its state-of-the-art NOC, enabling it to meet
      increasingly demanding customer requirements. The Company will continue to
      develop network-centric proprietary technologies and integrate third party
      technologies to optimize network performance and provide value-added
      network services to its customers. The Company currently focuses on new
      communications services offerings, such as back-up and recovery and wide
      area data caching, as well as real-time audio and video streaming and
      Internet telephony. Icon will seek to continue to develop its
      communications infrastructure to enhance the speed, security, reliability
      and overall performance of its network.
 
      Expand Network Domestically and Overseas. The Company plans to expand its
      network to specifically address the growing bandwidth and global reach
      requirements of its customers, both in the United States and
      internationally. Icon's agreement with MFS provides for access to MFS
      communications facilities throughout the country. The Company believes
      that the usage-based pricing model in its agreement with MFS enables it to
      enter new markets in a more advantageous manner than many of its
      competitors which, in many cases, must expend greater resources to build
      or lease facilities on a fixed-price basis. The Company also has
      agreements with other vendors who provide similar services, and the
      Company will pursue similar arrangements in the future as the Company
      continues to expand its network. In November 1997, the Company entered
      into a joint venture agreement with Teleway Corporation ('Teleway') that
      will extend the reach of the Company's network into Japan; however, this
      transaction is subject to third party and governmental consents and and no
      assurance can be made that the Company will obtain the required consents
      or that the transaction will otherwise be successful. Recently, Kokusai
      Denshain Denwa Co. Ltd. ('KDD') announced that it is in negotiations to
      acquire Teleway. The Company cannot predict the effect, if any, such
      acquisition would have on the joint venture.
 
      Expand and Integrate Professional Services Offerings. Icon's professional
      services include software application development, website design and
      development, integration with legacy systems, maintenance and support
      services and consulting. Unlike many of Icon's competitors, who focus on a
      single service or product, the Company continuously expands the breadth of
      its services and its engineering expertise to optimize its end-to-end
      solutions. The Company intends to continue
 
                                       36
 

<PAGE>
<PAGE>

      to develop and leverage both its expertise in designing graphical user
      interfaces (so-called 'front-end' design) and integrating with legacy data
      that resides on databases or mainframe systems (so-called 'back-end'
      integration).
 
      Continue to Build Efficient Distribution Through Direct and Indirect
      Channels. Icon will continue to grow its direct sales force, which has
      grown from 25 at the beginning of 1997 to 33 as of September 30, 1997. The
      direct sales force targets large accounts with significant revenue-
      generating potential. It focuses on information-intensive industries, such
      as financial services, media, telecommunications and travel. The Company
      believes that the organization of its direct sales force along industry
      lines enables it to leverage its expertise and develop solutions that can
      be replicated and tailored to meet recurring demands of corporate
      customers throughout a particular industry. In addition, the Company will
      continue to expand distribution relationships that enable it to compete
      effectively by expanding its customer base without substantial costs. The
      Company's indirect sales channels include relationships with
      telecommunications providers, such as Bell Atlantic Internet Solutions and
      Fiberlink, as well as resellers and master distributors. Bell Atlantic
      Internet Solutions offers its customers the option to select Icon as their
      global service provider to provide the long distance portion of the
      Internet access services. In October 1997, the Company extended its GSP
      agreement through October 1999 to continue to make its services available
      in the traditional Bell Atlantic southern region and to include the Bell
      Atlantic northern region (previously NYNEX) for dedicated access service.
      The Company currently plans that it will make its services available to
      Bell Atlantic Internet Solutions business customers in the northern region
      during the first half of 1998.
 
      Grow Through Acquisitions. The Company intends to strengthen its market
      position through acquisitions of companies that bring complementary
      expertise in certain segments of the Internet business and maximize value
      through cross-selling opportunities.
 
JOINT VENTURE
    
     In November 1997, the Company entered into an agreement with Teleway, a
Japanese communications company, pursuant to which they established Icon-Teleway
Internet Corporation ('ITIC'), to operate an Internet solutions business to
market end-to-end solutions to corporate customers in Japan (including Japanese
subsidiaries of United States corporations). Teleway, established in 1984, is
one of the largest long distance companies in Japan, with sales of approximately
$850 million in fiscal year 1996. Teleway will hold a 52% equity stake and Icon
will hold a 48% equity stake in ITIC, which will be formally established by the
first quarter of 1998. The services provided by ITIC will be similar to the
services provided by Icon in the United States, including communications
services, professional services and product resales. ITIC's network
infrastructure will be based on Teleway's nationwide ATM network.
     
     Teleway has agreed to provide ITIC an initial loan of /Y/1 billion
(approximately $8.3 million) and, upon request, to make an additional loan for
up to /Y/500 million (approximately $4.2 million) to fund operations. In
connection with the creation of the venture, the Company licensed to ITIC the
exclusive right to exploit Icon's intellectual property in Japan for a period of
five years. Any royalties received by Icon (up to a maximum of $8 million) will
be contributed back to ITIC as equity and will be matched by Teleway such that
the relative ownership is maintained. ITIC will use such equity contributions to
repay outstanding loans from Teleway and to fund operations. Icon and Teleway
have agreed to establish a network cross-connection between Icon's network in
the United States and Teleway's network in Japan. The parties have further
agreed to a reciprocal wholesale arrangement, on a 'most favored nations' basis,
pursuant to which Icon and ITIC will purchase communications services (including
Internet access) from each other at a wholesale price and resell such services
to customers in their respective countries. The transaction is subject to third
party and governmental consents.
 
     Recently, KDD announced that it is in negotiations to acquire Teleway. The
Company cannot predict the effect, if any, such acquisition would have on ITIC.
 
COMMUNICATIONS INFRASTRUCTURE
 
     The Company developed its communications infrastructure in recognition of
the market need for commercial-grade Internet access and value-added deployment
of mission-critical information and applications. The Company's customers use
the Company's communications infrastructure for private
 
                                       37
 

<PAGE>
<PAGE>

networks and commercial applications. The Company has developed proprietary
technologies that enhance network performance in terms of speed, reliability,
security and flexibility. See ' -- Research and Development.' The Company's
communications infrastructure is based upon an ATM architecture. As shown on the
map below, customers can connect to the Company's network from major cities
across the United States through dedicated high-speed leased lines. The network
is logically designed as a 'cloud,' with multiple high-speed paths between
switches, so as to reduce the possibility that any single point of failure will
cause network outage. The network uses state-of-the-art routing platforms,
including Cisco routers. Currently, the Company's backbone consists of 19 nodes,
and the Company currently plans to add several additional nodes.
 
MAP OF UNITED STATES AND THE COMPANY'S BACKBONE:
 
     After a customer's data has entered the Company's backbone, it is routed to
its destination, either over the Company's backbone or to another ISP's
backbone, which is facilitated through peering arrangements with other ISPs. In
order to peer with other Tier 1 ISPs, an ISP must demonstrate that its network
transports sufficient volumes of data and that it can peer at geographically
diverse locations. The Company has established Tier 1 peering arrangements with
other ISPs and long distance carriers enabling it to exchange traffic at major
peering points, including MAE-East, MAE-West, Ameritech Advanced Data Services
NAP, Digital Internet Exchange (including the CIX), Sprint Communications NAP
and Pacific Bell NAP. Peered ISPs share routing tables with each other so that
each ISP's customers can have access to the information on a peered-ISP's
network. Although many ISPs have recently been adding to their peering
eligibility requirements, the Company has been successful in qualifying for
these arrangements. The Company believes that the need to enter into peering
arrangements and the increasingly stringent eligibility standards to be met to
qualify for these relationships now provide a significant barrier to entry for
other companies trying to build nationwide backbones to provide Internet access.
The Company believes that its combination of a nationwide backbone and peering
arrangements establishes the Company as a Tier 1 provider, which differentiates
the Company from regional ISPs who, without peering arrangements, may have to
pay transit fees to national Internet carriers in order to exchange network
traffic.
 
     The Company's communications network consists of facilities leased from a
number of providers, including MFS, WorldCom and certain RBOCs, LECs and CAPs.
In June 1995, the Company entered into a service agreement with MFS that
provides the Company access to all of MFS' communications facilities throughout
the country. The Company believes that the usage-based pricing model in its
 
                                       38

<PAGE>

agreement with MFS enables it to enter new markets in a more advantageous manner
than many of its competitors which, in many cases, must expend greater resources
to build or lease facilities on a fixed-price basis. Furthermore, Icon's
agreement with MFS affords the Company the flexibility of converting to a fixed
price model, at its option, as utilization of facilities by the Company
increases. Pursuant to the agreement, MFS also provides certain additional
related services including, upon request by the Company, the provisioning of
local telecommunications services and co-location of certain of the Company's
equipment. Either MFS or Icon may terminate the agreement with or without cause,
with six months written notice, such termination to be effective as early as
December 1998. The Company has recently commenced discussions with MFS regarding
the potential extension of the agreement past December 1998 while at the same
time identifying alternative vendors who provide similar services to ensure the
continued uninterrupted operation of its high performance network. In November
1997, the Company entered into an agreement with Teleway pursuant to which they
established ITIC to operate an Internet solutions business to corporate
customers in Japan (including Japanese subsidiaries of United States
corporations); however, no assurance can be made at this time that this
transaction will be successful.
 
     The Company's network is monitored 24 hours per day, 7 days per week by its
NOC, located at its Weehawken, New Jersey headquarters. The NOC is the primary
control and networking equipment center for all forms of network operations.
Redundant network paths connect the NOC to the backbone, reducing the
possibility that a single point of failure will cause a network outage. The NOC
hosts systems, which consist of networking equipment, hardware and software, for
customers by providing space, connectivity, data protection and continuous
monitoring and maintenance. The Company maintains a second internal secure
network as a dedicated data conduit for backup and restoration of hosted client
data. To date, the Company has not experienced any network-wide outages or
significant losses of customer data.
 
SERVICES AND PRODUCTS
 
     The Company integrates services and products in three key areas: (i)
communications services, (ii) professional services and (iii) product resales.
 
     COMMUNICATIONS SERVICES
 
     Access Solutions. Icon's network access solutions enable customers to
deploy mission-critical information and applications over the Internet,
intranets and extranets. In some cases, the Company provides guaranteed levels
of service for dedicated Internet access to corporate customers and targets
performance benchmarks for connection success rates, latency levels and
throughput. The Company also provides switched Internet access including ISDN
and dial-up through Bell Atlantic Internet Solutions and may, in the future,
seek to expand its switched services to augment its dedicated offerings to its
corporate customers, who may want to provide switched access to their employees
or customers. In addition, the Company offers data back-up services by acting as
an outsourcer for archiving customers' data on its servers and systems, and
provides business recovery solutions by using its proprietary technologies. See
' -- Research and Development.'
 
     Depending upon the size of the customer and corresponding application and
information needs, bandwidth requirements vary widely. For example, audio and
video applications typically require greater bandwidth than text-based
applications. Icon offers five levels of Internet access to meet the wide range
of bandwidth needs:
 
       56 Kbps
 
       Fractional DS-1 (n x 64 Kbps; n<24)
 
       DS-1 (1.544 Mbps)
 
       Fractional DS-3 (n x 3 Mbps; 1<n<15)
 
       DS-3 (45 Mbps)
 
     Hosting and Management Solutions. Hosting and management solutions consist
of the provisioning, installation, maintenance and monitoring of the hardware
and software components that comprise a hosted system. The actual components of
web hosting are the server, the physical workstation or PC upon which the
website or application resides, the Company's NOC which hosts the server, a high
speed physical connection to the Company's backbone, server and power backup to
ensure 24 hour functionality, and maintenance, monitoring and management
services to ensure ongoing operation of
 
                                       39

<PAGE>

the server. Within both the NT and UNIX product lines, the Company offers a
diversity of hardware, software, network and service level configuration options
to meet the requirements of its sophisticated customer base. By outsourcing its
web server management function to the Company, a customer can reduce costs while
increasing reliability and performance of its servers. The Company offers 24
hours per day, 7 days per week monitoring of the server and Internet connection
through the Company's technical staff. In addition, Icon provides upgrades as
the customer's speed and capacity requirements grow. In addition to its existing
hosting facility at its corporate headquarters, the Company currently plans to
expand its hosting locations to include New York City and San Francisco.
 
     PROFESSIONAL SERVICES
 
     Custom Software Application Development. The Company designs and develops
specialized software applications that enable corporations to communicate
business information and conduct commerce through IP-based networks. The
Company's engineering staff is exprienced in programming languages such as C,
C++ and Java and works closely with its customers to analyze and design
specifications for IP-based applications. The Company has completed custom
application projects for customers including ABC Radio, The Associated Press,
Bear Stearns, CBS and Galileo.
 
     Website Design and Development. The Company is an established provider of
advanced website design and implementation services. The Company designs
websites ranging from basic 'inquiry only' sites to complex, interactive sites
featuring sophisticated graphics, animation, sound and other multimedia content.
The Company has completed website design projects for customers including Bell
Atlantic Internet Solutions, CBS News, a division of CBS, Comedy Central,
Deutsche Morgan Grenfell, Galileo, Eastman Kodak Company, Kobra International
(Nicole Miller), Swissair and Swissotel.
    
     In addition, the Company operates an interactive publishing unit that
produces three Internet-based media properties: Word'tm', a 'lifestyle'
publication targeted at 18-34 year olds; Charged'tm', focusing on the extreme
sports market; and SportsFan On-Line, a spectator-sports media property that
is a joint venture with Sports Fan Radio Network, a division of Winstar
Communications, Inc. The Company has experienced and expects to continue to
experience operating losses in connection with the ongoing operation of its
media properties. The Company has recently commenced efforts to identify
potential strategic partners to assist in the exploitation of these properties.
While it is the Company's desire to continue to design, produce and distribute
such properties, it does not intend to continue its role as publisher of
interactive media. The Company's interactive media properties have historically
operated at a loss, but have nevertheless served a valuable marketing function,
helping the Company attract employees and new business.
     
     Integration with Legacy Systems. The Company combines its expertise in
communications services, systems design and custom software and website design
and development to offer integration services. Icon's integration services
enable its customers to access corporate information that resides on legacy
systems, such as IBM or Unix mainframes, that are connected by network
architectures. The Company's technical engineers, whose training and
certification includes Sun Solaris, Netscape, Microsoft NT and Cisco, are
skilled at design and implementation of databases in order to reduce demands on
legacy systems and increase the efficiency of transporting corporate data
between legacy and client/server systems over an IP-based network. The Company
has completed integration projects for customers including ABC Radio, The
Associated Press, Bear Stearns, CBS News, Galileo, Merrill Lynch, Nomura
Securities, Omnipoint Communications ('Omnipoint'), Swissair, Tudor Investment
Company and John Wiley & Sons, Inc. ('John Wiley').
 
     Maintenance and Support of Customer IT Infrastructure. The Company's
maintenance and support services organization offers 24 hours per day, 7 days
per week hardware and software maintenance and support for its customers.
Services include call-in support, troubleshooting, software and hardware updates
and on-site helpdesk and general support personnel. Engagements of the Company
to perform maintenance and support services have often developed when or after
the customer has purchased products from the Company or used other professional
services. The Company has provided maintenance and support services for
customers including Bear Stearns, CBS, Merrill Lynch, Moore Capital Management,
Inc., Omnipoint, Tudor Investment Company and John Wiley.
 
     PRODUCT RESALES
 
     Product resales are an integral part of providing end-to-end solutions. The
Company identifies and resells hardware and software that become components of
its customers' information technology infrastructure. The Company, in certain
cases, leverages product resales to cross-sell Icon's end-to-end
 
                                       40
 

<PAGE>
<PAGE>

solutions to a growing customer base. The products include hardware and
networking equipment such as Sun Microsystems servers and Cisco routers, and
software such as Checkpoint firewalls, Netscape web servers and Oracle, Informix
and Sybase databases.
 
SALES AND MARKETING
     The Company's distribution strategy entails expanding its sales channels to
sell its services and products directly to commercial users and through a
network of indirect distribution channels, including OEM relationships, regional
systems integrators, VARs, distributors and relationships with
telecommunications companies, including Bell Atlantic Internet Solutions and
Fiberlink.
 
     DIRECT SALES FORCE
     The Company's direct sales force targets large accounts with significant
revenue-generating potential. The Company's sales group focuses on
information-intensive industries, such as financial services, media,
telecommunications and travel and includes customers such as ABC Radio, Bear
Stearns, CBS, Galileo and Nomura Securities. The Company believes that the
organization of its direct sales force along industry lines enables it to
leverage its expertise and develop solutions that can be replicated and tailored
to meet recurring demands of corporate customers throughout a particular
industry. As the size of the direct sales force grows, the Company plans to
expand into additional vertical segments, including general commercial and
consumer brand products. The Company has expanded its sales staff from 25 at the
beginning of 1997 to 33 as of September 30, 1997. Typically, the Company's sales
representatives receive a compensation package that includes a salary and
commissions that are based on actual sales and oriented toward selling higher
margin services.
 
     INDIRECT DISTRIBUTION CHANNELS
     The Company markets its services and products through a network of
third-party relationships, thereby expanding its customer base throughout the
country without incurring the associated sales, marketing and administrative
costs. Regional systems integrators, VARs and, in some cases, regional ISPs may
also resell the Company's services and products. By reselling the Company's
services and products, these companies are able to expand their service and
product offerings and provide more comprehensive solutions to their customers.
As an example of this strategy, the Company has entered into master distribution
agreements with Access Graphics and Merisel, two leading distributors of Sun
Microsystems Computer Company ('Sun') workstations, to bundle Sun web servers
with the Company's Internet access services. Such distributors and resellers may
participate in the Company's indirect distribution channel either by (i)
sublicensing the Company's services and products and reselling them to their
customers or (ii) referring orders to the Company in exchange for an agency
commission.
     Icon has also pursued a distribution strategy that enlists the assistance
of telecommunications companies who are already providing communications
services (such as local phone service or cable television) to existing
customers. This strategy enables the Company to leverage not only a
substantially larger sales and marketing infrastructure, but also strong
customer relationships. While the Company's margins are lower in this
distribution channel, the Company's resellers absorb all of the
customer-acquisition and administrative costs that would otherwise be borne by
the Company.
     In addition to its reseller agreements, pursuant to the arrangement with
Bell Atlantic Internet Solutions, Bell Atlantic Internet Solutions offers its
customers the option to purchase Icon's communications services and bills the
customers on Icon's behalf. In October 1997, the Company extended its
arrangement with Bell Atlantic Internet Solutions by entering into an updated
GSP agreement with Bell Atlantic Internet Solutions. The Company currently plans
to make its services available to requesting Bell Atlantic Internet Solutions
business customers in the Bell Atlantic northern region during the first quarter
of 1998. The Company intends to pursue additional relationships with other
telecommunications providers, including additional 'local telco service'
providers both using wireline and wireless facilities, including LECs, RBOCs,
CAPs and cable television companies.
 
     MARKETING
     The Company employs marketing and public relations personnel and works with
third-party advertising firms and consultants to provide broad coverage in
network computer and vertical industry publications. The Company participates in
nationwide industry trade shows, historically including NetWorld+InterOp,
Internet World and CompTel. The Company also participates in co-branding
promotions with strategic partners including Sun, Access Graphics and Merisel.
Recently, the Company expanded its marketing budget in an effort to increase its
brand recognition among potential customers in its target vertical markets.

     In 1994, 1995, 1996 and the first nine months of 1997, the Company derived
25%, 28%, 30%, respectively, and 49%, respectively, of its revenues from a
single customer, Bear Stearns. In 1994, 1995 and 1996, the Company derived 11%,
15% and 13%, respectively, of its revenues from a second customer, Nomura
Securities. In 1995, the Company derived 10% of its revenues from a third
customer, Merrill Lynch. Except for such revenues from such customers, the
Company did not derive 10% or more of its revenues from a single customer in
1994, 1995, 1996 or the first nine months of 1997.
 
KEY APPLICATIONS
 
     The following examples illustrate how the Company has provided
communications and professional services to facilitate access to and
distribution of mission-critical IP-based information and applications.
 
     BEAR, STEARNS & CO. INC.
 
     Historically, Icon had been a major technology product supplier for Bear
Stearns, reselling hardware and software products to the financial services
company since January 1994. In 1995, Bear Stearns hired the Company's
professional services unit to assist in the roll-out of desktop computers within
the firm. As part of the engagement, a number of the Company's engineers were
staffed on-site to assist with the installation and maintenance of the new
systems. Subsequently, Bear Stearns engaged Icon on projects to integrate Bear
Stearns' document management system into an IP-network through a web gateway and
to design, develop and implement its Correspondence System Project. Bear Stearns
also selected the Company to facilitate the migration of Bear Stearns' brokerage
clearing system to an IP-based network, to run the back-office transaction
processing on existing legacy networks and to operate Bear Stearns' systems and
mainframes consistent with its exacting reliability and security requirements.
Icon's solution included initial project consultation, design and development of
the application and IP-network, integration of the application and web gateway
with existing back-office legacy equipment and applications and associated
communications and maintenance services. With respect to this project, Icon
currently provides Internet access services, manages the server on which the
application resides, manages and maintains the IP-network and provides ongoing
consulting services. By implementing this solution, the Company believes that
Bear Stearns has been able to reduce the cost of maintaining a client/server
infrastructure, eliminate the need for application support on the PC level
through the use of Java and reduce WAN expenses by using the Company's network
rather than building its own.
 
     BELL ATLANTIC INTERNET SOLUTIONS
 
     In May 1996, Bell Atlantic Internet Solutions entered into an arrangement
to provide billing services in connection with the inclusion of Icon's
communications services as an option available to Bell Atlantic Internet
Solutions' customers. As a result of this arrangement, a significant percentage
of Bell Atlantic Internet Solutions' customers have selected Icon as their
global service provider to provide the long distance portion of the Internet
access services for both dedicated and switched access services. In light of the
success of this relationship, in June 1997, Bell Atlantic Internet Solutions
contracted with the Company to provide professional services to develop a
website for Bell Atlantic Internet Solutions' online marketing campaign. Icon's
professional services included the design and development of a system
architecture that facilitated users' access to product information and was
capable of distributing geographically specific information to users in
disparate locations. The Company also re-purposed existing marketing material to
take advantage of the interactive nature of the Internet. In October 1997, the
Company extended its arrangement with Bell Atlantic Internet Solutions by
entering into an updated GSP agreement with Bell Atlantic Internet Solutions.
The Company currently plans to make its services available to requesting Bell
Atlantic Internet Solutions customers in the northern region during the first
quarter of 1998.
 
     CBS, INC.
 
     Commencing in 1991, the Company began acting as a VAR for CBS. CBS
thereafter engaged Icon's professional services division to design and develop
an extranet to facilitate CBS' affiliates' access to
 
                                       43

programming information and CBS' ability to distribute real-time news and other
corporate information from internal databases. The Company provided consulting
services to help CBS design an efficient and cost-effective technology
infrastructure and integrate a streamlined data-filtering information
distribution application with back-end legacy databases and a web-based user
interface. In 1995, the customer selected Icon to provide hosting and Internet
access for the CBS website and other CBS-related websites. At the same time, CBS
selected Icon to develop and manage an Internet site providing live coverage of
the 1996 Presidential election, entitled 'Campaign '96.' The Company provided
CBS with an end-to-end solution, including design and implementation of the
back-end database architecture and the creation of dynamically-generated pages
with live streaming audio and video. The Company also provided hosted systems
management and maintenance and monitored bandwidth needs on a real-time basis.
In September 1997, CBS selected Icon as its communications services provider to
provide various services including hosting and access for the websites
'cbsnow.com' and 'cbs.com,' provide systems integration and infrastructure
planning services, and to provide technology products and associated
integration, maintenance and support services.
 
RESEARCH AND DEVELOPMENT
 
     To optimize overall network performance, Icon develops and markets
proprietary technologies. Icon's proprietary technologies are based on a modular
development approach that offers flexibility and allows for the reuse of
individual components and the rapid implementation of custom solutions. In
addition, Icon maintains a technology-neutral position thereby enabling it to
integrate third-party technologies to optimize its clients' solutions
irrespective of technology platform.
 
   
     OLive -- Objects Live. OLive'tm' is an object-oriented development platform
developed and used by the Company in the design of its proprietary technologies.
The Company designed OLive to simplify the development process of customized
network-centric applications solutions and is focused on re-usability,
interoperability and ease of customization.
    
 
   
     NESI. The protection of mission-critical data is of vital importance to a
company's business. As a result, corporations need business recovery
capabilities to replicate data in remote locations. To address data backup and
recovery needs, the Company developed NESI'tm', a technology that extends the
distance over which computers can communicate with peripherals such as disk
drives. Data can be sent over a WAN to be processed on a device at a remote
location, in the same manner as if the device were local. As a result,
administrative tools may be used to manage remote devices without modification.
Major benefits of NESI include the ability to be integrated with third-party
data mirroring products, such as Sun's Solstice DiskSuite and the Veritas Volume
Manager, and with data backup software. The Company plans to provide a business
recovery service by combining NESI with its proprietary IP replication
technology. IP replication technology redirects requests for data stored on a
specific server to one or more servers that are hosted on the Company's network
by replicating the IP address or identity of the original server. If data is
requested from a server that has failed, the request is re-directed to a
different NESI-enabled server that is storing a mirrored copy of the data. This
further improves recoverability of the data and speed of access to it. The
Company has a patent pending on the NESI technology.
    
 
   
     IconCache. End users often experience poor performance while waiting for
content to be downloaded from a web server. IconCache'tm', an OLive-based,
intelligent caching technology speeds this download process, enhancing the
access to and distribution of information over the Internet. Traditionally, when
end-users request data via the Internet, a server in a single location fulfills
the request. This configuration may result in poor performance due to high
server loads caused by overburdening the server with a high volume of requests
or increased latency or transmission delays caused by end-user requests
originating a significant distance from the server. IconCache improves network
performance by addressing both of these problems. Icon addresses server load and
distance-related latency problems in areas experiencing high request volume by
replicating server data and offloading or caching it to other servers.
Ultimately, IconCache diversifies single server loads and moves data closer to
the end-user, minimizing backbone traffic and enhancing performance. IconCache
is different from other caching technologies, such as proxy servers, that do not
provide high levels of data management and are typically used for simple static
websites. Icon plans to enhance the flexibility
    
 
                                       44

<PAGE>

of IconCache by combining it with IP replication. The Company has a patent
pending on this technology.
 
     IconFeed. In order to fulfill the growing need to publish and distribute
content over the Internet, Icon developed IconFeed'tm', an OLive-based content
publishing and distribution technology. IconFeed is an application that resides
on a server and receives data, regardless of format, and normalizes it for
optimal storage, maintenance and distribution on the web. The normalized data
can be stored in and accessed by a variety of data storage devices, including
databases and file systems. Ultimately, it is distributed and converted into a
format suitable for presentation via web servers, including HTML. The Company
has a patent pending on this technology.
 
     IconChat. The Internet enables the real-time interaction of end-users via
text, audio and video technologies. By incorporating these increasingly popular
interactive technologies into their websites, corporations are realizing
benefits, including the extended duration of end-user visits to revenue-
generating sites and the reduction of traditional communications costs. While
currently integrated with a third-party software product, IconChat'tm', a
text-based real-time discussion system, is the Company's first Internet-based
interactive offering. IconChat includes proprietary functionalities, including a
message board functionality that enables the electronic posting of messages
similar to that of a traditional bulletin board. The Company believes that
IconChat is ideal for corporate customers who want to facilitate real-time
text-based dialog among users of a company's website. It is offered as a
value-added service to Icon's communications services customers.
 
COMPETITION
 
     The markets served by the Company are extremely competitive. The influx of
new market entrants is expected to continue in each sector of the Company's
business to meet the growing demand for information technology and
communications services and products. Additionally, the Company believes that
such factors as shifting customer demands and the rapid pace of technological
advance will intensify competition and result in continual pressures to reduce
prices, enhance services and products and develop and exploit new technology.
Most of the Company's current and potential competitors enjoy a greater market
presence and possess substantially greater technical, financial and marketing
resources than the Company. The Company believes that its ability to compete
successfully depends upon a number of factors, including the performance,
reliability and security of its communications infrastructure, continued ability
to provide end-to-end Internet solutions, its ability to maintain and expand its
channels of distribution, its continued expertise in proprietary and third party
technologies, its ability to attract and retain service engineers, the pricing
policies of its competitors and suppliers, the variety of services it offers,
the timing of introductions of new services by the Company and its competitors,
customer support, the Company's ability to support industry standards and
industry and general economic trends.
 
     COMMUNICATIONS SERVICES
 
     The Company's current and prospective competitors in the Internet
communications services sector generally may be divided into the following five
groups: (i) telecommunications companies, such as AT&T, MCI, Sprint, WorldCom,
Intermedia, GTE and LECs; (ii) online services providers, such as America
Online, MSN and Prodigy; (iii) ISPs, such as NETCOM, PSI, Concentric and other
national and regional providers; (iv) cable modem connectivity providers such as
@Home; and (v) data center providers such as Exodus. Most of these competitors
have greater market presence, engineering and marketing capabilities, and
financial, technological and personnel resources than those available to the
Company. As a result, they may be able to develop and expand their
communications infrastractures more quickly, adapt more swiftly to new or
emerging technologies and changes in customer requirements, take advantage of
acquisition and other opportunities more readily, and devote greater resources
to the marketing and sale of their services and products than the Company. In
addition to the companies named above, various organizations have entered into
or are forming joint ventures or consortiums to provide services similar to
those of the Company. The Company believes that competitive factors in the
Internet services market include market presence, network capacity, reliability
and security, price, new products and enhancements and conformity with industry
standards.
 
                                       45
 

<PAGE>
<PAGE>

     Certain companies, including WorldCom, Intermedia and GTE, have also
obtained or expanded their Internet access services and products as a result of
acquisitions. In 1996, MFS merged with UUNET, a competitor of the Company in the
area of Internet access. MFS has been acquired by WorldCom, which is also a
supplier of network services to Icon. WorldCom has reached an agreement to
acquire MCI, which is a major provider of Internet backbone services. The
combination of MFS, UUNET, WorldCom and MCI means that one of the Company's
major suppliers is also one of its formidable competitors in providing Internet
services. Such acquisitions may permit the Company's competitors to devote
greater resources to the development and marketing of new competitive products
and services and the marketing of existing competitive products and services.
Additionally, certain distributors of the Company's services and products, such
as Bell Atlantic Internet Solutions, may compete with the Company in the future.
Certain companies are also providing high-speed data services using alternative
delivery methods such as cable television, direct broadcast satellites and
wireless cable.
 
     As a result of increased competition and vertical and horizontal
integration and consolidation in the industry, the Company could encounter
significant pricing pressure, which in turn could result in significant
reductions in the average selling price of the Company's services. For example,
certain of the Company's competitors that are telecommunications companies may
be able to provide customers with reduced communications costs in connection
with their Internet access services or private network services, reducing the
overall cost of their solutions and significantly increasing price pressures on
the Company. There can be no assurance that the Company will be able to offset
the effects of any such price reductions with an increase in the number of its
customers, higher revenue from enhanced services, cost reductions or otherwise.
 
     PROFESSIONAL SERVICES
 
     The professional services market is highly fragmented and served by
numerous providers, including consulting and systems integration firms,
facilities management and MIS outsourcing companies, applications software
firms, major equipment providers through their professional services units,
major accounting firms, general management consulting firms and website/intranet
design firms. The Company typically encounters competition from mid-sized and
regional consulting and systems integration firms, such as Cambridge Technology
Partners and Technology Solutions, and increasingly competes with large-scale
systems integrators, such as EDS. The Company's design group also competes with
a variety of interactive design firms including agency.com, Razorfish, USWeb and
CKS Group. The Company believes that the primary competitive factors at work in
this market are price, the ability to fashion and deliver efficient solutions to
customer needs, the quality of service, including project management and ongoing
support and maintenance, its ability to attract and retain service engineers and
the availability and quality of hardware. Accordingly, the Company competes on
the basis of its reputation, personnel, technical sophistication and ability to
provide single-source, end-to-end solutions.
 
     PRODUCT RESALES
 
     The product resales business is a highly competitive market with low
margins and no substantial barriers to entry. The Company believes that its
ability to compete successfully depends on a number of factors, including its
ability to integrate value-added services with its product resales, the price at
which the Company resells products, the speed and accuracy of delivery, the
effectiveness of sales and marketing programs, credit availability, the ability
to tailor specific solutions to customer needs, the quality and breadth of
products offered, the availability to offer product information and technical
support and industry and general economic trends.
 
     The Company's current and prospective competitors generally can be divided
into three groups: (i) national and regional VARs, such as EJV Bridge Networks,
Bell Technology and LANCOM; (ii) national and regional systems integrators, such
as EDS, Sapient, Computer Associates and The Ergonomics Group; and (iii)
hardware distributors, such as CHS Electronics and ITOCHU. Many of these
competitors have greater market presence and financial resources than those
available to the Company. As a result, they may be able to adapt more swiftly to
changes in market prices and customer requirements, provide financing to
customers for purchases, take advantage of acquisition and other opportunities
more readily, and devote greater resources to the marketing and sale of their
products
 
                                       46
 

<PAGE>
<PAGE>

than can the Company. In addition, the Company expects that additional
competitive pressure may arise from manufacturers that have been successful in
selling directly to the end-users without the use of resellers.
 
PROPRIETARY RIGHTS
 
     The Company believes that factors such as the technical and business
expertise of its personnel, attentive high-quality customer service and
strategic alliances with its suppliers and other vendors, have to date played a
predominant role in promoting its reputation and the growth of its business but
recognizes that its ability to compete effectively and to continue to grow will
depend increasingly on the use and appeal of its proprietary technology. While
the Company relies on patent, trademark, contract, trade secret and copyright
law to protect its proprietary technologies, it is possible for a third party to
copy or otherwise obtain and use the Company's technologies without
authorization, or to develop similar technologies independently. Although the
Company has not to date registered any trademark or service mark, it has applied
to register its name and logo design as trademarks and certain of its product
and service names and marks as trademarks or service marks in the United States.
The Company does not own but has applied for patents on certain of its
proprietary technologies. Although the Company does not believe that its
services or products infringe the proprietary rights of any third parties, there
can be no assurance that third parties will not assert such claims against the
Company in the future or that such claims will not be successful.
 
     In accordance with the Company's policy, all of the Company's employees and
consultants have entered into, and all future employee and consultants are
expected to enter into, agreements containing confidentiality and
nonsolicitation covenants. Similarly, the Company's agreements with customers
and suppliers include provisions prohibiting or restricting the disclosure of
proprietary information and products, the use of software in source code form
and the sublicensing of licensed software. The Company also monitors and limits
access to and the distribution of its proprietary technologies. In addition, the
Company sells or licenses its services and products in, and the Internet and
other global networks facilitate the delivery of the Company's software to,
other countries where the laws may not afford adequate protection of the
Company's proprietary rights in such products or provide effective means for its
enforcement of such rights.
 
     Certain technologies used in the Company's solutions are licensed or leased
by the Company, generally on a non-exclusive basis. There can be no assurance
that such technology will continue to be available to the Company on
commercially reasonable terms. The loss of such technology could impair the
Company's products or services or require the Company to obtain substitute
technologies of lower quality or performance standards or at greater cost. See
'Risk Factors -- Dependence on Proprietary Technologies'.
 
GOVERNMENTAL REGULATION
 
     The Company believes it is not currently subject to direct regulation by
the FCC or any other governmental agency, other than regulations applicable to
businesses generally. To date, the FCC has not actively sought to regulate the
provision of Internet access and related services. Except for the stand-alone
provision of underlying basic transmission capability, the offering of Internet
services or access to the Internet has generally been considered an 'enhanced
service,' a type of services offering that is not currently regulated by the
FCC. Whether the FCC will assert regulatory authority over the Internet and the
level of such regulation, if asserted, are pending issues at that agency, and
regulation of the Internet and related services in general is being considered
by lawmakers at many levels of government. The Company cannot predict whether
regulation may be imposed in the future, what form such regulation may take or
that such regulation will not adversely affect the Company's business, financial
condition or results of operations.
 
     Under current law, operators of 'enhanced' services are exempt from FCC
regulation, but operators of 'basic' services are not similarly exempt. The FCC
has not yet addressed whether providing transport services, including Internet
telephony, to customers over an IP-based network is an enhanced service. A
determination by the FCC that providing Internet transport or telephone services
 
                                       47
 

<PAGE>
<PAGE>

to customers over an IP-based network is subject to regulation would adversely
impact the Company's ability to provide various existing and planned services
and to provide Bell Atlantic Internet Solutions' customers with the option to
purchase the Company's communications and other services, and could have a
material adverse effect on the Company's business, financial condition and
results of operations. Some states may, however, seek to exercise regulatory
jurisdiction over certain aspects of such offerings.
 
     The FCC also extensively regulates the cable and broadcasting industries.
These regulations address, among other things, technical, ownership, competition
and content-related issues. To date, the FCC has not determined whether or to
what extent its regulatory framework can or should be extended to directly
govern analogous communications on the Internet, such as video and audio
streaming. There can be no guarantee that the limited regulatory burdens on the
Internet to date will not increase or that new laws governing the Internet will
not be passed.
 
     In February 1996, the Telecommunications Act of 1996 was signed into law by
the President of the United States. Changes in the regulatory environment
relating to the Internet access industry, including regulatory changes that
directly or indirectly affect the regulatory status of Internet services, affect
telecommunications costs, including the application of access charges to
Internet services, or increase the likelihood or scope of competition from
regional telephone companies or others, could have a material adverse effect on
the Company's business, financial condition and results of operations. Due to
the increase in Internet use and publicity, it is possible that laws and
regulations may be adopted with respect to the Internet, including with respect
to privacy, pricing and characteristics of services or products. Certain other
legislative initiatives, including those involving taxation of Internet services
and transactions, Internet regulation and universal service contribution
requirements for Internet providers have also been proposed. The Company cannot
predict the impact, if any, that these or other laws and regulations or legal or
regulatory changes may have on its business.
 
     In addition, Bell Atlantic has filed a petition with the FCC seeking relief
from various regulations that affect the deployment of advanced
telecommunications services by RBOCs. The petition asks the FCC to approve Bell
Atlantic's (i) provision of high-speed broadband services without regard to
current geographic restrictions, (ii) development of new services without
current pricing, unbundling or separations restrictions and (iii) sale of new
services unrestricted by otherwise applicable price cap and separate affiliate
rules. If the FCC approves the petition, Bell Atlantic or Bell Atlantic Internet
Solutions may be able to undertake many of the functions that the Company
currently performs for Bell Atlantic Internet Solutions' customers. The FCC has
invited public comment on Bell Atlantic's request.
 
     Recently the FCC proposed to eliminate the requirement that RBOCs must file
comparably efficient interconnection plans and obtain approval for those plans
prior to providing new enhanced services. Elimination of this requirement could
lessen certain regulatory burdens currently imposed on Bell Atlantic Internet
Solutions. Furthermore, on December 31, 1997, a Federal District Court Judge
declared several provisions of the Telecommunications Act unconstitutional. If
upheld on appeal, this decision may allow Bell Atlantic to offer certain
services, which Bell Atlantic Internet Solutions and its affiliates have been
prohibited from offering under the Telecommunications Act, without the FCC
finding Bell Atlantic to be in compliance with the network unbundling and other
competitive requirements set out in the Telecommunications Act. The Company
currently provides such services for Bell Atlantic Internet Solutions'
customers; and if the decision is upheld on appeal, Bell Atlantic Internet
Solutions or its affiliates may provide such services directly to their
customers.
 
     Bell Atlantic Internet Solutions' relationship with the Company is subject
to review and regulation by state and federal authorities, including the FCC.
Although the Company understands that Bell Atlantic Internet Solutions has
received the requisite approvals to provide service and make the Company's
services available to those of Bell Atlantic Internet Solutions' customers who
request them (which has only included customers in the traditional Bell Atlantic
southern region through the date of this Prospectus), a petition submitted by
MFS in July 1996 for reconsideration of such FCC approvals is currently pending
before the FCC. Additionally, the extension of the Company's service offerings
into the traditional Bell Atlantic northern region (NYNEX) is subject to
approvals at the state and federal levels. There can be no assurance that Bell
Atlantic Internet Solutions will be successful in maintaining or procuring the
requisite regulatory approvals. Failure of Bell Atlantic Internet Solutions to
maintain or prospectively procure such approvals at the federal or state level
could adversely affect the
 
                                       48
 

<PAGE>
<PAGE>

Company's existing agreements with Bell Atlantic Internet Solutions, and, as a
result, the Company's business, financial condition and results of operations.
 
     Additionally, certain lobbying groups are attempting to initiate
legislation which would compel ISPs to pay access charges for the use of some of
the local networks operated by the RBOCs. The adoption of such laws or
regulations could inhibit the continued growth of the Internet or other wide
area information networks, impose additional costs on the Company, expose the
Company to greater potential liability from regulatory actions or private legal
proceedings or otherwise adversely affect the Company's business operations or
performance. However, at present, the Company is unable to predict whether any
laws or regulations specifically applicable to the Company or its businesses
will be adopted, or, if any such laws or regulations are adopted, the nature or
extent of their impact on the information technology industry or the Company's
business operations or performance.
 
     Federal and state laws and regulations relating to the liability of online
services companies and Internet access providers for information carried on or
disseminated through their networks is currently unsettled. Several private
lawsuits seeking to impose such liability upon online services companies and
Internet access providers are currently pending.
 
     In addition, legislation has been enacted and new legislation has been
proposed that imposes liability for or prohibits the transmission on the
Internet of certain types of information. The imposition upon the Company and
other Internet access providers of potential liability for information carried
on or disseminated through their systems could require the Company to implement
measures to reduce its exposure to such liability, which may require the
expenditure of substantial resources, or to discontinue certain service or
product offerings. The increased attention focused upon liability issues as a
result of these lawsuits and legislative actions and proposals could impact the
growth of Internet use. While the Company carries professional liability
insurance, it may not be adequate to compensate or may not cover the Company in
the event the Company becomes liable for information carried on or disseminated
over its networks. See 'Risk Factors -- Government Regulation.'
 
LEGAL PROCEEDINGS
 
     The Company is not a party to, nor is any of its property the subject of,
any material pending legal proceedings.
 
EMPLOYEES
 
     As of September 30, 1997, the Company had 229 employees, all of whom were
full time. Of these, 98 were principally engaged in professional services, 28

engaged in the interactive publishing group, 36 were principally engaged in
sales and marketing, 13 were principally engaged in research and development, 10
were principally engaged in operations and 33 were principally engaged in
finance, administration, legal, management information systems and human
resources. None of the Company's employees is represented by a labor union. The
Company considers its relations with its employees to be satisfactory.
 
PROPERTIES
 
     The Company currently occupies approximately 55,000 square feet in a modern
office building in Weehawken, New Jersey, under a lease which expires on
February 28, 2006. The Company's NOC is located at its Weehawken building. The
Company also leases approximately 5,700 square feet for its New York City office
and is negotiating a possible lease of approximately 20,000 square feet of space
to replace the existing New York City office.

automatically granted immediately following each annual meeting of stockholders

EMPLOYMENT AGREEMENTS
 
     In December 1995, the Company entered into five-year employment agreements
with Messrs. Baxter, Brown and Harmolin. In May 1997, each of the agreements was
amended to extend the employment term until May 2002. The agreements provide for
Mr. Baxter to serve as the Company's Chief Executive Officer and President, for
Mr. Brown to serve as the Company's Vice President -- Information Technologies
and Secretary and for Mr. Harmolin to serve as the Company's Senior Vice
President and Chief Technology Officer at a minimum annual base salary of
$185,000, $180,000 and $180,000, respectively. Mr. Baxter's agreement also
provides for the payment of a guaranteed quarterly bonus in the amount of
$30,000, and Mr. Brown's and Mr. Harmolin's agreements each provide for the
payment of a guaranteed quarterly bonus in the amount of $10,000. Each also
receives additional salary increases and bonuses as the Board of Directors may
grant, as well as those benefits generally provided to other executive officers
of the Company, and an automobile allowance. In the event of termination of
employment of any of such executives following a change of control (as defined
in such employment agreements) of the Company, the Company has agreed to pay the
respective executive severance in an amount equal to 2.99 multiplied by his base
amount (as defined in section 280G(b)(3) of the Internal Revenue Code of 1986,
as amended (the 'Code')). Each executive has also agreed not to compete against
the Company during the term of his employment, and not to solicit or perform
services for any customers or solicit any employee of the Company during the
term of his employment and for a period of 12 months after the termination of
his employment.
 
     In February and March 1997, the Company entered into employment agreements
with Messrs. Cicio and Hall, respectively, pursuant to which they are
employees-at-will. The agreements provide for each to be paid a minimum annual
base salary of $200,000 and a performance-based bonus. If either is terminated
without cause, he is entitled to receive his salary compensation otherwise
payable for a period of six months; provided, however, that if the Company has
extended such employee's related non-compete agreement, then such employee is
entitled to receive his salary compensation otherwise
 
                                       53
 

<PAGE>
<PAGE>

payable for a period of 12 months. Messrs. Cicio and Hall were each granted an
option to purchase 109,091 and 87,273 shares of Common Stock, respectively.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The Company did not have a compensation committee during the fiscal year
ended December 31, 1996; its function was performed by the Board of Directors.
Messrs. Baxter, Brown and Harmolin, as the three members of the Board of
Directors, each participated in deliberations concerning executive officer
compensation. In June 1997, the Company established a Compensation Committee and
an Audit Committee. The members of the Compensation Committee are Messrs.
Baxter, Brown, Harmolin and Weisman and the members of the Audit Committee are
Messrs. Baxter, Harmolin and Weisman. Upon the consummation of this Offering,
the Board of Directors intends to reconstitute the Audit Committee such that a
majority of the members of such Committee will be non-employee directors (as
defined in Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as
amended).
 
1995 OPTION PLAN
 
     In October 1995, the Board of Directors adopted and the stockholders of the
Company approved the 1995 Option Plan. The 1995 Option Plan provides for the
grant of (i) options that are intended to qualify as incentive stock options
('Incentive Stock Options') within the meaning of Section 422 of the Code to key
employees (including directors and officers who are key employees) and (ii)
options not intended so to qualify ('Nonqualified Stock Options') to key
employees (including directors and officers who are key employees of the
Company), non-employee directors and consultants. The total number of shares of
Common Stock for which options may be granted under the 1995 Option Plan is
2,181,818 shares.
 
     The 1995 Option Plan is to be administered by the Board of Directors, which
will determine to whom options are granted, the number of shares subject to such
options, and the terms, exercise prices and other terms and conditions of the
exercise thereof.
 
     The exercise price of any Incentive Stock Option granted under the 1995
Option Plan must be at least equal to the fair market value of the shares
subject to such option on the date of grant, while the exercise price of any
Incentive Stock Option granted to any participant who owns stock possessing more
than 10% of the total combined voting power of the Company's outstanding capital
stock must be at least equal to 110% of the fair market value of the shares
subject to such option on the date of grant. The determination of fair market
value is made by the Board of Directors based primarily upon reference to the
fair market value of recent sales of the Company's securities to unrelated third
parties. The term of each Incentive Stock Option granted pursuant to the 1995
Option Plan cannot exceed ten years, while the term of any Incentive Stock
Option granted to a participant who owns stock possessing more than 10% of the
total combined voting power of the Company's outstanding capital stock cannot
exceed five years. Options become exercisable at such times and in such
installments as is provided in the option contract for each individual option.
No option granted under the 1995 Option Plan is transferable by the optionee
other than by will or the laws of descent and distribution and each option is
exercisable during the lifetime of the optionee only by such optionee.
 
     Pursuant to option contracts granted to certain executive officers and
certain key employees of the Company, the vesting of certain unvested options
granted to such individuals will accelerate (i) upon such individual's
termination of employment without cause, as a result of death or as a result of
disability and (ii) upon certain changes in control (each, an 'Acceleration
Date'). Pursuant to such agreements, the options otherwise exercisable within up
to three years (depending on the terms of the option contract such individual
has negotiated with the Company) will vest upon the occurrence of an
Acceleration Date.
 
     As of the date of this Prospectus, under the 1995 Option Plan, the Company
has granted to certain of its employees options to purchase up to 1,186,286
shares of Common Stock at an exercise price between $6.02 and $13.48 per share,
of which options with respect to 245,273 shares are currently exercisable and
the balance thereof becomes exercisable at various times after January 15, 1998.
The Company has also granted to one of its former employees options to purchase
up to 65,455 shares of
 
                                       54
 

<PAGE>
<PAGE>

Common Stock at an exercise price of $14.27 per share, all of which options are
currently exercisable. All such options have terms of ten years, and provide
that, upon the earliest to occur of the death, permanent total disability or
termination without cause of employment of the option holder, such option will
become immediately exercisable with respect to all shares of Common Stock
subject thereto as to which such option would otherwise have been exercisable
within three years after the occurrence of such event.
 
AGREEMENTS WITH EMPLOYEES
 
     Each employee of the Company is required to enter into an agreement with
the Company pursuant to which such person agrees (i) to assign to the Company
any inventions relating to such person's employment conceived during such
person's employment by the Company, (ii) not to disclose confidential
information to third parties, (iii) not to engage in any business that is
competitive with the Company during the term of such person's employment, (iv)
not to hire any employee of the Company during such person's employment and for
a period of 12 months following the termination of such person's employment and
(v) not to perform services for any customer of the Company for a period of 12
months following the termination of such person's employment. The agreement also
provides that the employee is an 'at will' employee and that either the Company
or the employee may terminate employment with the Company at any time with or
without cause.
 
401(k) PLAN
 
     In January 1993 the Company adopted a tax-qualified employee savings and
retirement plan (the '401(k) Plan') covering the Company's employees. Pursuant
to the 401(k) Plan, employees may elect to reduce their current compensation by
up to the lesser of 10% of eligible compensation or the statutorily prescribed
annual limit ($9,500 in 1997) and have the amount of such reduction contributed
to the 401(k) Plan. The trustees under the 401(k) Plan, at the direction of each
participant, invest the assets of the 401(k) Plan. The 401(k) Plan is intended
to qualify under Section 401 of the Code so that contributions by employees to
the 401(k) Plan, and income earned on plan contributions, are not taxable to
employees until withdrawn.
 
PROFIT SHARING PLAN
 
     The Company has a profit sharing plan covering substantially all full-time
employees. Contributions by the Company to the profit sharing plan amounted to
$129,000 and $28,000 in 1994 and 1996, respectively. There were no contributions
to the profit sharing plan during 1995 and the nine months ended September 30,
1997.

                              CERTAIN TRANSACTIONS
 
     On August 30, 1995, the Company made loans of $50,000 to Messrs. Baxter,
Brown and Harmolin. Interest accrues at an annual rate of 7%. The loans
including accrued interest are due on demand.
 
     Messrs. Baxter, Brown and Harmolin are party to a Stockholders' Agreement
dated as of July 17, 1995, as amended, pursuant to which, in the event any of
them desires to accept an offer from a third-party to purchase any shares of
Common Stock owned by such stockholder, the Company and the other two
stockholders have the right to purchase such shares at a price that is adjusted
annually pursuant to the mutual agreement of Messrs. Baxter, Brown and Harmolin
(the 'Agreed Upon Price'). If any of Messrs. Baxter, Brown or Harmolin becomes
disabled, is terminated for any reason, engages in a competitive business or is
adjudicated bankrupt, then the Company and the remaining two stockholders have
the right to purchase all the shares then owned by such stockholder at the
Agreed Upon Price. Upon the death of any of them, the Company is obligated to

obligated to sell such shares, at the Agreed Upon Price.

L.P. ('TAP'), loaned to the Company an aggregate principal amount of $1.0
million pursuant to a convertible note bearing interest at a rate of 10% per
annum. In consideration for such loan, the Company granted to such lenders a
warrant to purchase an aggregate of 41,511 shares of Common Stock at an exercise
price of $6.02 per share. On May 30, 1997, such lenders converted the $1.0
million note and $20,000 of accrued but unpaid interest thereon into an
aggregate of 10,200 shares of Series B Preferred Stock.

shares of preferred stock, par value $.01 per share (the 'Preferred Stock'),
450,000 shares of which are designated as Series A Convertible Participating
Preferred Stock and 415,000 shares of which are designated as 10% PIK Series B
Convertible Participating Preferred Stock. Upon consummation of the Offering,
15,025,285 shares of Common Stock will be issued and outstanding and no shares
of Preferred Stock will be outstanding. The discussion herein describes the
Company's capital stock, Restated Certificate of Incorporation and Restated
By-laws. The following summary description of the Company's capital stock
describes all material provisions of, but does not purport to be complete and is
subject to, and qualified in its entirety by, the Restated Certificate of
Incorporation and the Restated By-laws of the Company that are included as
exhibits to the Registration Statement of which this Prospectus forms a part and
by the provisions of applicable law.
 
COMMON STOCK
 
     As of September 30, 1997, there were 6,545,454 shares of Common Stock
outstanding held by three holders of record. The issued and outstanding shares
of Common Stock are, and the shares of Common Stock being offered will be upon
payment therefor, validly issued, fully paid and non-assessable. Subject to the
prior rights of the holders of any Preferred Stock, the holders of outstanding
shares of Common Stock are entitled to receive dividends out of assets legally
available therefor at such times and in such amounts as the Board of Directors
may from time to time determine. See 'Dividend Policy'. Following consummation
of the Offering, shares of Common Stock will not be redeemable or convertible,
and the holders thereof will have no preemptive or subscription rights to
purchase any securities of the Company. Upon liquidation, dissolution or winding
up of the Company, the holders of Common Stock are entitled to receive pro rata
the assets of the Company which are legally available for distribution, after
payment of all debts and other liabilities and subject to the prior rights of
any holders of Preferred Stock then outstanding. Each outstanding share of
Common Stock is entitled to one vote on all matters submitted to a vote of
stockholders.
 
     The Common Stock has been approved for listing on the NNM under the symbol
'ICMT', subject to official notice of issuance.
 
PREFERRED STOCK
 
     As of September 30, 1997, there were 422,607 shares of Series A Preferred
Stock outstanding, which shares were sold by the Company in January 1996 for an
aggregate of $9.9 million, held by approximately 60 holders of record. The
issued and outstanding shares of Series A Preferred Stock are validly issued,
fully paid and non-assessable. Pursuant to the terms of the Certificate of
Incorporation in effect prior to the Offering, upon the consummation of this
Offering, the shares of Series A Preferred Stock will be converted automatically
into 1,637,061 shares of Common Stock. Each share of Series A Preferred Stock
converts into approximately 3.87 shares of Common Stock at the option of the
holder and automatically upon consummation of a public offering by the Company
in which it receives at least $20 million in gross proceeds or the sale of all
or substantially all of the Company's assets or outstanding capital stock, each
at a price of at least $12.05 per share of Common Stock.
 
     As of September 30, 1997, there were 180,240 shares of Series B Preferred
Stock outstanding, which shares were sold by the Company from May through
September 1997 for an aggregate of $18.0 million, held by 18 holders of record.
The issued and outstanding shares of Series B Preferred Stock are validly
issued, fully paid and non-assessable. Pursuant to the terms of the Certificate
of Incorporation in effect prior to the Offering, upon the consummation of the
Offering, the shares of Series B Preferred Stock will be converted automatically
into 2,992,770 shares of Common Stock. Each share of Series B Preferred Stock
converts into approximately 16.60 shares of Common Stock at the option of the
holder and automatically upon consummation of a public offering by the Company
in which it receives at least $20 million in gross proceeds or the sale of all
or substantially all of the Company's assets or outstanding capital stock, each
at a price of at least $12.05 per share of Common Stock.

<PAGE>

     The Company's Board of Directors may, without further action by the
Company's stockholders, from time to time, direct the issuance of up to
1,000,000 shares of Preferred Stock in series and may, at the time of issuance,
determine the rights, preferences and limitations of each series. Satisfaction
of any dividend preferences of outstanding shares of Preferred Stock would
reduce the amount of funds available for the payment of dividends on shares of
Common Stock. Holders of shares of Preferred Stock may be entitled to receive a
preference payment in the event of any liquidation, dissolution or winding-up of
the Company before any payment is made to the holders of shares of Common Stock.
Under certain circumstances, the issuance of shares of Preferred Stock may
render more difficult or tend to discourage a merger, tender offer or proxy
contest, the assumption of control by a holder of a large block of the Company's
securities or the removal of incumbent management. The Board of Directors of the
Company, without stockholder approval, may issue shares of Preferred Stock with
voting and conversion rights which could adversely affect the holders of shares
of Common Stock. Upon consummation of the Offering, there will be no shares of
Preferred Stock outstanding, and the Company has no present intention to issue
any shares of Preferred Stock.
 
WARRANTS
 
     There are currently outstanding warrants to purchase an aggregate of
948,891 shares of Common Stock, of which warrants to purchase 68,180 shares of
Common Stock have an exercise price of $.03 and warrants to purchase 880,711
shares of Common Stock have an exercise price of $6.02. Of the warrants with an
exercise price of $.03, 15,542 expire on January 29, 2001; 94 expire on March
14, 2001; 50,042 expire on May 30, 2007; and 2,502 expire on September 2, 2007.
Of the warrants with an exercise price of $6.02, 41,511 expire on December 31,
2002; 838,199 expire on May 30, 2007; and 1,001 expire on September 2, 2007. The
warrants have customary anti-dilution provisions.
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
     Pursuant to an Investors' Rights Agreement among the Company and the
holders of the Series A Preferred Stock, dated as of January 30, 1996,
Registration Rights Agreements between the Company and each holder of the Series
B Preferred Stock, dated between May 30, 1997 and September 22, 1997 and certain
warrants issued by the Company (collectively, the 'Registration Rights
Agreements'), certain securityholders of the Company (the 'Holders') that will
own approximately 4,629,831 shares of Common Stock, shares of Common Stock
issuable upon exercise of warrants to purchase 933,255 shares of Common Stock
and 891,744 warrants to purchase Common Stock (collectively, the 'Registrable
Securities') or their permitted transferees are entitled to registration rights
with respect to the Registrable Securities at any time following the earlier of
(i) 180 days following consummation of the Offering and (ii) January 30, 1999.
Additionally, the holders of warrants to purchase 15,636 shares of Common Stock
have the right to register such shares of Common Stock on a registration
statement filed by the Company.
 
     Under the terms of the Registration Rights Agreements between the Company
and the Holders of such Registrable Securities, if the Company proposes to
register any of its securities under the Securities Act, either for its own
account or for the account of other securityholders exercising registration
rights, such Holders are entitled to notice of such registration and are
entitled to include their Registrable Securities therein at the Company's
expense; such Holders, however, have waived their right to register their
Registrable Securities in the Offering. Holders of Registrable Securities also
have the right to demand that the Company file a registration statement under
the Securities Act, subject to certain conditions and limitations, among them
the right of the underwriters of an offering to limit the number of shares
included in such registration in certain circumstances.
 
CERTAIN ANTI-TAKEOVER CHARTER PROVISIONS AND STATUTORY PROVISIONS
 
     The Restated Certificate of Incorporation requires that special meetings of
the stockholders of the Company be called only by a majority of the Board of
Directors or by certain officers. The Restated Certificate of Incorporation also
provides that the Board of Directors shall be divided into three classes, with
each class containing as equal a number of directors as possible; after an
interim period of three years following consummation of the Offering, all
directors will be elected for three years and only one class of directors will
come up for election each year. The Restated Certificate of Incorporation
further
 
                                       60
 

<PAGE>
<PAGE>

provides that the Company's by-laws may only be amended by the affirmative vote
of two-thirds of the shares of the Company entitled to vote for the election of
directors or by a majority of the Board of Directors, but that certain
provisions may only be amended or repealed by the affirmative vote of two-thirds
of the shares of the Company entitled to vote for the election of directors.
Pursuant to the Restated Certificate of Incorporation, each of the foregoing
provisions may only be amended by a two-thirds vote of the shares of the Company
entitled to vote for the election of directors.
 
     The Company's Board of Directors may, without further action by the
Company's stockholders, from time to time, direct the issuance of up to
1,000,000 shares of Preferred Stock. Under certain circumstances the issuance of
shares of Preferred Stock may render more difficult or tend to discourage a
merger, tender offer or proxy contest, the assumption of control by a holder of
a large block of the Company's securities or the removal or incumbent
management.
 
     The Restated By-laws provide that stockholders seeking to bring business
before or to nominate directors at any annual meeting of stockholders must
provide timely notice thereof in writing. To be timely, a stockholder's notice
must be delivered to, or mailed and received at, the principal executive offices
of the Company not less than 60 days nor more than 90 days prior to such meeting
or, if less than 70 days' notice was given for the meeting, within 10 days
following the date on which such notice was given. The Restated By-laws also
will specify certain requirements for a stockholder's notice to be in proper
written form. These provisions will restrict the ability of stockholders to
bring matters before the stockholders or to make nominations for directors at
meetings of stockholders.
 
     Following the consummation of the Offering, the Company will be subject to
the 'business combination' provisions of the Delaware General Corporation Law.
In general, such provisions prohibit a publicly held Delaware corporation from
engaging in various 'business combination' transactions with any 'interested
stockholder' for a period of three years after the date of the transaction in
which the person became an 'interested stockholder,' unless (i) the transaction
is approved by the Board of Directors prior to the date the interested
stockholder obtained such status, (ii) upon consummation of the transaction
which resulted in the stockholder becoming an 'interested stockholder,' the
'interested stockholder' owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced, excluding for
purposes of determining the number of shares outstanding those shares owned by
(a) persons who are directors and also officers and (b) employee stock plans in
which employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer, or (iii) on or subsequent to such date the 'business combination' is
approved by the board of directors and authorized at an annual or special
meeting of stockholders by the affirmative vote of at least 66 2/3% of the
outstanding voting stock which is not owned by the 'interested stockholder.' A
'business combination' is defined to include mergers, asset sales and other
transactions resulting in financial benefit to a stockholder. In general, an
'interested stockholder' is a person who, together with affiliates and
associates, owns (or within three years, did own) 15% or more of a corporation's
voting stock. The statute could prohibit or delay mergers or other takeover or
change in control attempts with respect to the Company and, accordingly, may
discourage attempts to acquire the Company.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     The Restated Certificate of Incorporation limits the liability of directors
for breach of fiduciary duty as a director except for (i) breach of the duty of
loyalty to the Company or its stockholders, (ii) acts not in good faith,
involving intentional misconduct or knowing violation of law, (iii) certain
violations of the Delaware General Corporation Law and (iv) transactions where
the director derived an improper benefit. In addition, the Restated Certificate
of Incorporation provides that the Company shall indemnify directors, officers,
employees and agents of the Company acting in such capacity to the fullest
extent permitted by such law.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock will be Chase Mellon
Shareholder Services, L.L.C.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion the Offering the Company will have 15,025,285 shares of
Common Stock outstanding (15,371,785 shares if the over-allotment option is
exercised in full). The 3,850,000 shares of Common Stock (4,427,500 shares if
the over-allotment option is exercised in full) sold in the Offering will be
freely tradeable without restriction or further registration under the
Securities Act, unless held by an 'affiliate' of the Company as that term is
defined in Rule 144 promulgated under the Securities Act ('Rule 144'), which
shares will be subject to the resale limitations of Rule 144. The remaining
11,175,285 shares of Common Stock have not been registered under the Securities
Act and may not be sold unless they are registered or unless an exemption from
registration, such as the exemption provided by Rule 144 or Rule 701 under the
Securities Act ('Rule 701'), is available.
 
     In general, under Rule 144 as currently in effect, a stockholder (or
stockholders whose shares are aggregated) who has beneficially owned shares
constituting 'restricted securities' (generally defined as securities acquired
from the Company or an affiliate of the Company in a non-public transaction) for
at least one year, is entitled to sell within any three-month period a number of
shares that does not exceed the greater of one percent of the outstanding Common
Stock or the average weekly trading volume in the Common Stock during the four
calendar weeks preceding the date on which notice of such sale is filed pursuant
to Rule 144. Sales under Rule 144 are also subject to certain provisions
regarding the manner of sale, notice requirements and the availability of
current public information about the Company. A stockholder (or stockholders
whose shares are aggregated) who is not an affiliate of the Company for at least
90 days prior to a proposed transaction and who has beneficially owned
'restricted securities' for at least two years is entitled to sell such shares
under Rule 144 without regard to the limitations described above. Rule 701
provides that, beginning 90 days after the date of this Prospectus, shares of
Common Stock acquired on the exercise of options outstanding prior to the date
of this Prospectus may be resold by persons other than affiliates of the Company
without regard to the current public information, holding period, volume
limitations and notice provision of Rule 144, and by affiliates subject to all
the provisions of Rule 144 except its one-year minimum holding period.
Accordingly, the Company believes that, under prevailing interpretations of
Rules 144 and 701, 6,545,454 shares of Common Stock that constitute 'restricted
securities' will be eligible for sale, subject to the contractual lock-up
provisions described below, 90 days after the date of this Prospectus, and
4,629,831 shares of Common Stock would be eligible for sale beginning one year
from the date of this Prospectus, subject to certain volume and other
limitations under Rule 144. The Company intends to file one or more registration
statements under the Securities Act to register the shares of Common Stock
issued and reserved for issuance in compensatory arrangements and under the 1995
Option Plan. Registration would permit the resale of such shares by
non-affiliates and affiliates, subject to the lock-up described below, in the
public markets without restriction under the Securities Act.
 
     The Company and the holders of more than 10.7 million shares of Common
Stock (including, among others, the Company's executive officers, directors
owning securities of the Company before the Offering and the Selling
Stockholders) have agreed that, for a period of 180 days after the date of this
Prospectus, they will not (i) offer, sell, contract to sell, pledge or otherwise
dispose of, directly or indirectly, or, in the case of the Company, file with
the Securities and Exchange Commission a registration statement under the
Securities Act relating to, any shares of Common Stock or securities convertible
into or exchangeable or exercisable for any shares of Common Stock, or publicly
disclose the intention to make any such offer, sale, contract to sell, pledge,
disposition or, in the case of the Company, filing, or (ii) enter into any swap
or other agreement that transfers, in whole or in part, any of the economic
consequences of ownership of such shares of Common Stock, whether any
transaction described in clause (i) or (ii) above is to be settled by delivery
of shares of Common Stock or such other securities, in cash or otherwise, in
each case without the prior written consent of Credit Suisse First Boston
Corporation, except in the case of the Company, issuances of Common Stock
pursuant to the conversion or exchange of convertible or exchangeable securities
or the exercise of warrants or options, in each case outstanding on the date of
this Prospectus, grants of employee stock options pursuant to the 1995 Option
Plan and issuances of Common Stock pursuant to the exercise of such options, and
except in the case of an individual, bona fide gifts or similar transfers to or
for the benefit, directly or indirectly, of members of such individual's family
for estate planning purposes provided that such gifts or transfers are made
other than on any securities exchange or in the over-the-counter market and that
 
                                       62

<PAGE>

such donees or transferees agree to terms substantially similar to the foregoing
for the benefit of the Company and the Underwriters.
 
     In addition, after the Offering, the holders of 4,629,831 shares of Common
Stock will be entitled to certain rights with respect to registration of such
shares under the Securities Act. Registration of such shares under the
Securities Act would result in such shares becoming freely tradeable without
restriction under the Securities Act (except for shares purchased by affiliates
of the Company) immediately upon the effectiveness of such registration. See
'Description of Capital Stock -- Registration Rights of Certain Holders'.
 
     Prior to the Offering, there has been no public trading market for the
shares of Common Stock, and there can be no assurance that a regular trading
market will develop after the Offering, or that if it is developed, it will be
sustained. In addition, no prediction can be made as to the effect, if any, that
market sales of shares of Common Stock or the availability of such shares for
sale will have on the market prices prevailing from time to time. Nevertheless,
the possibility that substantial numbers of shares of Common Stock may be sold
in the public market may adversely affect prevailing market prices for the
shares of Common Stock and could impair the Company's ability to raise capital
through the sale of its equity securities.
 
                       CERTAIN UNITED STATES FEDERAL TAX
                        CONSEQUENCES TO NON-U.S. HOLDERS
 
     The following is a general summary of certain U.S. Federal income and
estate tax consequences expected to result under current law from the purchase,
ownership, sale or other taxable disposition of Common Stock by any person or
entity other than (a) a citizen or resident of the United States, (b) a
corporation created or organized in or under the laws of the United States or of
any State thereof (including the District of Columbia), (c) an estate or trust
described in Section 7701(a)(30) of the Internal Revenue Code of 1986, as
amended (the 'Code') or (d) a person or entity otherwise subject to U.S. Federal
income taxation on income from sources outside the United States (a 'Non-U.S.
Holder'). This summary does not address all U.S. Federal income and estate tax
considerations that may be relevant to Non-U.S. Holders in light of their
particular circumstances or to certain Non-U.S. Holders that may be subject to
special treatment under U.S. Federal income tax laws. Furthermore, this summary
does not discuss any aspects of foreign, state or local taxation. This summary
is based on current provisions of the Code, existing, temporary and proposed
regulations promulgated thereunder and administrative and judicial
interpretations thereof, all of which are subject to change, possibly with
retroactive effect. No legal opinion is being rendered to the Company in respect
of the United States tax consequences to a holder of Common Stock who is a
non-U.S. Holder. PROSPECTIVE PURCHASERS OF COMMON STOCK ARE ADVISED TO CONSULT
THEIR TAX ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES OF ACQUIRING, HOLDING
AND DISPOSING OF COMMON STOCK.
 
DIVIDENDS
 
     Dividends paid to a Non-U.S. Holder of Common Stock generally will be
subject to withholding of U.S. Federal income tax at a 30% rate (or such lower
rate as may be specified by an applicable income tax treaty) unless the dividend
is (a) effectively connected with the conduct of a trade or business of the
Non-U.S. Holder within the United States or (b) if a tax treaty applies, is
attributable to a United States permanent establishment of the Non-U.S. Holder,
in which cases the dividend will be taxed at ordinary U.S. Federal income tax
rates. If the Non-U.S. Holder is a corporation, such effectively connected
income may also be subject to an additional 'branch profits tax.' A Non-U.S.
Holder may be required to satisfy certain certification requirements in order to
claim treaty benefits or otherwise claim a reduction of, or exemption from, the
withholding obligation pursuant to the above described rules.
 
SALE OR OTHER DISPOSITION OF COMMON STOCK
 
     A Non-U.S. Holder generally will not be subject to U.S. Federal income or
withholding tax in respect of any gain recognized on the sale or other taxable
disposition of Common Stock unless (a) the gain is effectively connected with a
trade or business of the Non-U.S. Holder in the United States; (b) in
 
                                       63
 

<PAGE>
<PAGE>

the case of a Non-U.S. Holder who is an individual and holds the Common Stock as
a capital asset, the holder is present in the United States for 183 or more days
in the taxable year of the disposition and satisfies certain other conditions;
(c) the Non-U.S. Holder is subject to tax pursuant to the provisions of U.S.
Federal income tax law applicable to certain United States expatriates; or (d)
(i) the Company is or has been during certain periods preceding the disposition
a 'U.S. real property holding corporation' for U.S. Federal income tax purposes
(which the Company does not believe it is or is likely to become) and, (ii)
assuming that the Common Stock will be 'regularly traded on an established
securities market' for tax purposes, the Non-U.S. Holder held, directly or
indirectly, at any time during the five-year period ending on the date of
disposition, more than 5% of the outstanding Common Stock.
 
BACKUP WITHHOLDING AND REPORTING REQUIREMENTS
 
     On October 6, 1997, the Internal Revenue Service issued final regulations
relating to withholding, information reporting and backup withholding that unify
current certification procedures and forms and clarify reliance standards (the
'Final Regulations'). The Final Regulations generally will be effective with
respect to payments made after December 31, 1998. Except as provided below, this
section describes rules applicable to payments made on or before December 31,
1998.
 
     Dividends. United States backup withholding tax generally will not apply to
dividends paid on Common Stock to a Non-U.S. Holder at an address outside the
United States. The Company must report annually to the Internal Revenue Service
and to each Non-U.S. Holder the amount of dividends paid to, and the tax
withheld with respect to, such holder, regardless of whether any tax was
actually withheld. This information may also be made available to the tax
authorities in the Non-U.S. Holder's country of residence.
 
     Sale or Other Disposition of Common Stock. Upon the sale or other taxable
disposition of Common Stock by a Non-U.S. Holder to or through a United States
office of a broker, the broker must backup withhold at a rate of 31% and report
the sale to the Internal Revenue Service, unless the holder certifies its
Non-U.S. status under penalties of perjury or otherwise establishes an
exemption. Upon the sale or other taxable disposition of Common Stock by a
Non-U.S. Holder to or through the foreign office of a United States broker, or a
foreign broker with certain types of relationships to the United States, the
broker must report the sale to the Internal Revenue Service (but not backup
withhold), unless the broker has documentary evidence in its files that the
seller is a Non-U.S. Holder and/or certain other conditions are met, or the
holder otherwise establishes an exemption.
 
     Amounts withheld under the backup withholding rules generally are allowable
as a credit against such Non-U.S. Holder's U.S. Federal income tax liability (if
any), which may entitle such Non-U.S. Holder to a refund, provided that the
required information is furnished to the Internal Revenue Service.
 
     The Final Regulations eliminate the general prior legal presumption that
dividends paid to an address in a foreign country are paid to a resident of that
country. In addition, the Final Regulations impose certain certification and
documentation requirements on Non-U.S. Holders claiming the benefit of a reduced
withholding rate with respect to dividends under a tax treaty or otherwise
claiming a reduction of, or exemption from, the withholding obligation described
above.
 
     PROSPECTIVE PURCHASERS OF THE COMMON STOCK ARE URGED TO CONSULT THEIR OWN
TAX ADVISORS AS TO THE EFFECT, IF ANY, OF THE FINAL REGULATIONS ON THEIR
PURCHASE, OWNERSHIP AND DISPOSITION OF THE COMMON STOCK.
 
FEDERAL ESTATE TAXES
 
     Common Stock owned or treated as owned by an individual Non-U.S. Holder who
is not a citizen or resident (as specially defined for U.S. Federal estate tax
purposes) of the United States at the time of death will be included in such
individual's gross estate for U.S. Federal estate tax purposes, unless an
applicable estate tax treaty provides otherwise.

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will be obligated to purchase all the shares of Common Stock
offered hereby (other than those shares covered by the over-allotment option
described below) if any are purchased. The Underwriting Agreement provides that,
in the event of a default by an Underwriter, in certain circumstances the
purchase commitments of non-defaulting Underwriters may be increased or the
Underwriting Agreement may be terminated.
 
     Under the Underwriting Agreement, the Company and the Selling Stockholders
have granted to the Underwriters an option, exercisable by Credit Suisse First
Boston Corporation on behalf of the Underwriters, expiring at the close of
business on the 30th day after the date of this Prospectus, to purchase up to
346,500 additional shares from the Company and an aggregate of 231,000
additional outstanding shares from the Selling Stockholders at the initial
public offering price less the underwriting discounts and commissions, all as
set forth on the cover page of this Prospectus. Such option may be exercised
only to cover over-allotments in the sale of the shares of Common Stock offered
hereby. To the extent such option is exercised, each Underwriter will become
obligated, subject to certain conditions, to purchase approximately the same
percentage of additional shares being sold to the Underwriters as the number of
shares set forth next to such Underwriter's name in the preceding table bears to
the total number of shares. Any shares of Common Stock purchased pursuant to the
exercise of such option will be purchased first from the Selling Stockholders
and thereafter from the Company.
 
     The Company has been advised by the Representatives that the Underwriters
propose to offer the shares of Common Stock offered hereby to the public
initially at the offering price set forth on the cover page of this Prospectus
and, through the Representatives, to certain dealers at such price less a
concession of $     per share and that the Underwriters and such dealers may
allow a discount of $     per share on sales to certain other dealers. After the
initial public offering, the public offering price and concession and discount
to dealers may be changed by the Representatives.
 
     In July 1997, an employee of Credit Suisse First Boston Corporation
purchased 200 shares of Series B Preferred Stock for an aggregate cash
consideration of $20,000. Such 200 shares of Series B Preferred Stock are deemed
to be underwriting compensation received by Credit Suisse First Boston
Corporation in connection with the Offering under Rule 2710 of the National
Association of Securities Dealers, Inc. Conduct Rules ('Rule 2710'). Pursuant to
Rule 2710, such employee has agreed that, for a period of one year following the
date on which the Registration Statement relating to the Offering, of which this
Prospectus constitutes a part, is declared effective by the Securities and
Exchange Commission, he will not, subject to certain exceptions, sell, transfer,
assign, pledge or hypothecate (i) such 200 shares of Series B Preferred Stock or
(ii) the shares of Common Stock into which such 200 shares of Series B Preferred
Stock are convertible.
 
     The Representatives have informed the Company that they do not expect
discretionary sales by the Underwriters to exceed 5% of the number of shares of
Common Stock offered hereby.
 
     The Company and the holders of more than 10.7 million shares of Common
Stock (including, among others, the Company's executive officers, directors
owning securities of the Company before the
 
                                       65
 

<PAGE>
<PAGE>

Offering and the Selling Stockholders) have agreed that, for a period of 180
days after the date of this Prospectus, they will not (i) offer, sell, contract
to sell, pledge or otherwise dispose of, directly or indirectly, or, in the case
of the Company, file with the Securities and Exchange Commission a registration
statement under the Securities Act relating to, any shares of Common Stock or
securities convertible into or exchangeable or exercisable for any shares of
Common Stock, or publicly disclose the intention to make any such offer, sale,
contract to sell, pledge, disposition or, in the case of the Company, filing, or
(ii) enter into any swap or other agreement that transfers, in whole or in part,
any of the economic consequences of ownership of such shares of Common Stock,
whether any transaction described in clause (i) or (ii) above is to be settled
by delivery of shares of Common Stock or such other securities, in cash or
otherwise, in each case without the prior written consent of Credit Suisse First
Boston Corporation, except in the case of the Company issuances of Common Stock
pursuant to the conversion or exchange of convertible or exchangeable securities
or the exercise of warrants or options, in each case outstanding on the date of
this Prospectus, grants of employee stock options pursuant to the 1995 Option
Plan and issuances of Common Stock pursuant to the exercise of such options, and
except in the case of an individual, bona fide gifts or similar transfers to or
for the benefit, directly or indirectly, of members of such individual's family
for estate planning purposes provided that such gifts or transfers are made
other than on any securities exchange or in the over-the-counter market and that
such donees or transferees agree to terms substantially similar to the foregoing
for the benefit of the Company and the Underwriters.
 
     The Company has reserved for purchase from the Underwriters at the initial
public offering price up to 192,500 shares of Common Stock which may be
purchased by certain employees of the Company and certain other individuals
through a directed share program. The number of shares of Common Stock available
for sale to the general public in the Offering will be reduced to the extent
such persons purchase the reserved shares. Any reserved shares not so purchased
will be offered by the Underwriters to the general public on the same terms as
the other shares offered hereby.
 
     The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including civil liabilities under the
Securities Act, and to contribute to payments which the Underwriters may be
required to make in respect thereof.
 
     The Common Stock has been approved for listing on the NNM under the symbol
'ICMT', subject to official notice of issuance.
 
     Prior to the Offering there has been no public market for the Common Stock.
The initial public offering price for the Common Stock will be determined by
negotiation between the Company and Credit Suisse First Boston Corporation on
behalf of the Underwriters and does not necessarily reflect the market price of
the Common Stock following the Offering. Among the principal factors to be
considered in determining the initial public offering price will be market
conditions for initial public offerings, the history of and prospects for the
Company's business, the Company's past and present operations, its past and
present earnings and current financial position, an assessment of the Company's
management, the market of securities of companies in businesses similar to those
of the Company, the general condition of the securities markets and other
relevant factors. There can be no assurance that the initial public offering
price will correspond to the price at which the Common Stock will develop and
continue after the Offering.
 
     The Representatives, on behalf of the Underwriters, may engage in
over-allotment, stabilizing transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Securities Exchange Act
of 1934, as amended. Over-allotment involves syndicate sales in excess of the
offering size, which creates a syndicate short position. Stabilizing
transactions permit bids to purchase the underlying security so long as the
stabilizing bids do not exceed a specified maximum. Syndicate covering
transactions involve purchases of the Common Stock in the open market after the
distribution has been completed in order to cover syndicate short positions.
Penalty bids permit the Representatives to reclaim a selling concession from a
syndicate member when Common Stock originally sold by such syndicate member is
purchased in a syndicate covering transaction to cover syndicate short
positions. Such stabilizing transactions, syndicate covering transactions and
penalty bids may cause the price of the Common Stock to be higher than it would
otherwise be in the absence of such transactions. These transactions may be
effected on the NNM or otherwise and, if commenced, may be discontinued at any
time.

RESALE RESTRICTIONS
 
     The distribution of the Common Stock in Canada is being made only on a
private placement basis exempt from the requirement that the Company and the
Selling Stockholders prepare and file a prospectus with the securities
regulatory authorities in each province where trades of Common Stock are
effected. Accordingly, any resale of the Common Stock in Canada must be made in
accordance with applicable securities laws which will vary depending on the
relevant jurisdiction, and which may require resales to be made in accordance
with available statutory exemptions or pursuant to a discretionary exemption
granted by the applicable Canadian securities regulatory authority. Purchasers
are advised to seek legal advice prior to any resale of the Common Stock.
 
REPRESENTATIONS OF PURCHASERS
 
     Each purchaser of Common Stock in Canada who receives a purchase
confirmation will be deemed to represent to the Company, the Selling
Stockholders and the dealer from whom such purchase confirmation is received
that (i) such purchaser is entitled under applicable provincial securities laws
to purchase such Common Stock without the benefit of a prospectus qualified
under such securities laws, (ii) where required by law, that such purchaser is
purchasing as principal and not as agent, and (iii) such purchaser has reviewed
the text above under 'Resale Restrictions.'
 
ENFORCEMENT OF LEGAL RIGHTS
 
     All of the issuer's directors and officers as well as the experts named
herein and the Selling Stockholders may be located outside of Canada and, as a
result, it may not be possible for Canadian purchasers to effect service of
process within Canada upon the issuer or such persons. All or a substantial
portion of the assets of the issuer and such persons may be located outside of
Canada and, as a result, it may not be possible to satisfy a judgment against
the issuer or such persons in Canada or to enforce a judgment obtained in
Canadian courts against such issuer or persons outside of Canada.
 
NOTICE TO BRITISH COLUMBIA RESIDENTS
 
     A purchaser of Common Stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
Common Stock acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from the Company. Only one
such report must be filed in respect of Common Stock acquired on the same date
and under the same prospectus exemption.
 
TAXATION AND ELIGIBILITY FOR INVESTMENT

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
ICON CMT CORP.
 
     In our opinion, the accompanying balance sheet and the related statements
of operations, of changes in stockholders' equity (deficit) and of cash flows
present fairly, in all material respects, the financial position of Icon CMT
Corp. (the 'Company') at December 31, 1995 and 1996 and September 30, 1997, and
the results of its operations and its cash flows for each of the three years in
the period ended December 31, 1996 and the nine months ended September 30, 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 statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audits to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.
 
     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 2 to the
financial statements, the Company has incurred substantial operating losses,
expects to incur substantial additional losses and expects that its cash and
working capital requirements will continue to increase as the Company's
operations continue to expand. These and other factors, as discussed in Note 2,
raise substantial doubt about its ability to continue as a going concern.
Management's plans in regards to these matters are also described in Note 2. The
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
                (UNAUDITED WITH RESPECT TO THE NINE MONTH PERIOD
                           ENDED SEPTEMBER 30, 1996)
               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
1. ORGANIZATION AND BUSINESS
 
ORGANIZATION
 
     Icon CMT Corp. (the 'Company' or 'Icon') was incorporated in February 1995
under the laws of the State of Delaware for the purpose of merging with
Integration Consortium, Inc. (the 'Predecessor'), which was incorporated in 1991
under the laws of the State of New York. In July 1995, the stockholders of the
Predecessor exchanged their shares of the Predecessor for 6,545,454 shares of
the common stock of Icon and the Predecessor became a wholly owned subsidiary of
Icon. A merger of Icon and the Predecessor was effected in December 1995, and
pursuant to the merger agreement, Icon was the surviving entity. The share
exchange and subsequent merger has been accounted for in a manner similar to a
pooling of interests. References herein to the operations and historical
financial information of the 'Company' prior to the date of the share exchange
refer to the operations and historical financial information of the Predecessor.
Unless the context otherwise requires, all other references herein to the
'Company' refer to Icon.
 
BUSINESS
 
     From inception through 1994, the Company was primarily engaged in the
design, marketing, sale, installation and on-going support of information
management systems and distribution of information over networks. Through 1994,
the Company primarily generated revenue through the sales of hardware and
services to migrate its customers' networks to local client/server environments
and by managing, maintaining and expanding those networks.
 
     During 1995 the Company began its transition to become an end-to-end
Internet solutions provider to corporate customers. The Company currently
derives its revenues from the following services and products: (i) professional
services including custom application development and design, systems
integration and maintenance and support services, (ii) high quality Internet
access and related communications services such as web/server hosting and
management and (iii) product resales, including hardware and software, as a part
of systems design and integration.
 
2. BASIS OF PRESENTATION
 
     The Company has incurred significant operating losses for the year ended
December 31, 1996 and the nine months ended September 30, 1997. At December 31,
1996 and September 30, 1997 the Company had an accumulated deficit of $8,073 and
$17,161, respectively, and working capital of ($1,900) and $5,090, respectively.
Such losses have resulted principally from general and administrative and
selling and marketing expenses associated with the Company's expanded level of
operations. The Company expects that its cash and working capital requirements
will continue to increase as the Company's operations continue to expand and it
will require additional financing to achieve its business objectives. In order
to fund these efforts, the Company completed private placements of its
mandatorily redeemable Series A Convertible Participating Preferred Stock (the
'Series A Preferred') during 1996 (Note 6) and its mandatorily redeemable 10%
PIK Series B Convertible Participating Preferred Stock (the 'Series B
Preferred') during the nine months ended September 30, 1997. The Company
utilized the net proceeds from these issuances for the repayment of short-term
debt and working capital, including marketing and product line expansions.
 
     The accompanying financial statements have been prepared assuming the
Company will continue as a going concern. The Company's significant net
operating losses, expected substantial additional losses and increasing working
capital requirements raise substantial doubt about the Company's present ability
to continue as a going concern. The Company's ability to continue as a going
concern is dependent upon its ability to generate sufficient cash flow to meet
its obligations as they come due.

                                 ICON CMT CORP.
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                (UNAUDITED WITH RESPECT TO THE NINE MONTH PERIOD
                           ENDED SEPTEMBER 30, 1996)
               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
     At September 30, 1997, the Company had an option to issue and sell up to an
additional 50,000 shares of Series B Preferred to investors at a per share price
of $100.00 to fund its future cash requirements (Note 6). Additionally, the
Company had a secured line of credit available at September 30, 1997 (Note 5).
 
     Management is also actively pursuing other financing options which include
securing additional equity financing through an initial public offering and
believes that sufficient funding will be available to meet its planned business
objectives; however, there can be no assurance that the Company will be
successful in its efforts to raise additional capital. The financial statements
do not include any adjustments relating to the recoverability of the carrying
amount of recorded assets or the amount of liabilities that might result from
the outcome of these uncertainties.
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ACCOUNTING ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
SERVICES REVENUE
 
     Revenue from custom software development, database design, outsourcing and
corporate website production is recognized as the services are rendered or on a
percentage of completion basis for contracts requiring milestone achievements
prior to invoicing.
 
     Revenue from communications services, such as Internet access, hosting
services, on-site maintenance, product enhancements and telephone support, is
recognized ratably over the period of the agreement as the services are
provided, typically one year.
 
     Revenue from sponsorships of digital publications is recognized ratably
over the period in which the sponsorship is displayed on a website or webzine
produced by the Company.
 
     Unbilled costs and accrued earnings consist primarily of services performed
which were not billed at the end of the period due to specific contractual terms
established with certain customers.
 
PRODUCTS REVENUE
 
     Revenue from the resale of products, which consist of high-end
non-proprietary network hardware and software products, is recognized upon
shipment to the customer when no significant vendor obligations exist and
collectibility is probable.
 
DEFERRED REVENUE
 
     Deferred revenue consists principally of billings in advance for services
not yet provided.
 
CASH EQUIVALENTS
 
     Cash equivalents consist of short-term, highly liquid investments, with
original maturities of less than three months when purchased and are stated at
cost. Interest is accrued as earned.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                (UNAUDITED WITH RESPECT TO THE NINE MONTH PERIOD
                           ENDED SEPTEMBER 30, 1996)
               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
INVENTORIES
 
     Inventories, which consist principally of purchased computer hardware, are
stated at the lower of cost (determined on a first-in, first-out basis) or
market value.
 
EQUIPMENT
 
     Equipment is stated at cost. Depreciation is provided on a straight-line
basis over the estimated useful lives of the respective assets, none of which
exceeds five years. Depreciation expense related to equipment used solely for
communications-related services is included in services cost of revenues.
 
RESEARCH AND DEVELOPMENT
 
     The Company charges all costs incurred to establish the technological
feasibility of a product or product enhancement to research and development
expense.
 
INCOME TAXES
 
     Income taxes are accounted for under the asset and liability method.
Deferred income taxes are recorded for temporary differences between financial
statement carrying amounts and the tax basis of assets and liabilities. Deferred
tax assets and liabilities reflect the tax rates expected to be in effect for
the years in which the differences are expected to reverse. A valuation
allowance is provided if it is more likely than not that some or all of the
deferred tax asset will not be realized.
 
   
EARNINGS (LOSS) PER COMMON SHARE
    
 
   
     Effective December 31, 1997 the Company adopted Financial Accounting
Standards No. 128, 'Earnings per Share' ('FAS 128') which requires presentation
of basic earnings per share ('Basic EPS') and diluted earnings per share
('Diluted EPS') by all entities that have publicly traded common stock or
potential common stock (options, warrants, convertible securities or contingent
stock arrangements). FAS 128 also requires presentation of earnings per share by
an entity that has made a filing or is in the process of filing with a
regulatory agency in preparation for the sale of those securities in a public
market. Basic EPS is computed by dividing income available to common
stockholders by the weighted average number of common shares outstanding during
the period. Diluted EPS gives effect to all dilutive potential common shares
outstanding during the period. The computation of Diluted EPS does not assume
conversion, exercise or contingent exercise of securities that would have an
antidilutive effect on earnings.
    
 
   
     All prior periods presented have been restated for the adoption of FAS 128.
The adoption of FAS 128 did not have a significant impact on the earnings (loss)
per share of prior periods. The computations of basic earnings (loss) per share
and diluted earnings (loss) per share for the years ended December 31, 1994,
1995, 1996 and for the nine months ended September 30, 1996 and 1997 are as
follows:

common stock, with exercise prices ranging from $6.02 to $14.27 have been
excluded from the computation of diluted loss per share as they are
antidilutive. Outstanding warrants to purchase 948,891 shares of common stock,
with exercise prices ranging from $0.03 to $6.02, were also antidilutive and
excluded from the computation of diluted loss per share at September 30, 1997.

INTERIM FINANCIAL DATA
 
   
     The unaudited financial data for the nine months ended September 30, 1996
has been prepared by management and include all adjustments, consisting only of
normal recurring adjustments, necessary to present fairly the results of
operations and cash flows. The results of operations for the nine months ended
September 30, 1997 are not necessarily indicative of the operating results to be
expected for the year ended December 31, 1997.
    
 
RECLASSIFICATIONS
 
     Certain prior year amounts have been reclassified to conform with their
1997 presentation.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying value of accounts receivable, notes receivable, accounts
payable, accrued expenses and notes payable approximate their fair values due to
the relatively short maturity of these instruments.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
   
     In June 1997, the FASB issued Financial Accounting Standards No. 130,
'Reporting Comprehensive Income' ('FAS 130'), which requires the presentation of
the components of comprehensive income in a company's financial statements for
reporting periods beginning subsequent to December 15, 1997. Comprehensive
income is defined as the change in a company's equity during a financial
reporting period from transactions and other circumstances from nonowner sources
(including cumulative translation adjustments, minimum pension liabilities and
unrealized gains/losses on available-for-sale

5. NOTES PAYABLE
 
SECURED LINE OF CREDIT
 
     On August 14, 1995, the Company obtained a secured line of credit with a
bank for $3,000 which expired on June 30, 1996. Borrowings under this line were
secured by certain assets of the Company. At December 31, 1995, borrowings under
this line amounted to $3,000. Interest was charged at the bank's prime rate plus
one percent, which was 9.5% at December 31, 1995. Interest expense amounted to
$78 and $25 in 1995 and 1996, respectively. This line of credit was repaid in
full on January 31, 1996.
 
     On August 13, 1996, the Company obtained a secured line of credit with a
lending institution for $10,000 which expires on August 13, 1998. Borrowings
under this line are secured by substantially all of the assets of the Company.
Borrowings under this line are limited to a specified percentage of qualifying
accounts receivable less outstanding obligations of the Company owed to the
lending institution including outstanding letters of credit. The payment of cash
dividends is prohibited under this secured line of credit. At December 31, 1996,
borrowings under this line amounted to $2,194 and no amounts were outstanding at
September 30, 1997. Interest is payable monthly at an annual rate equal to the
lending institution's prime rate plus one percent, which was 9.25% and 9.50% at
December 31, 1996 and September 30, 1997, respectively. The rate adjusts on the
first of the month following any change. Interest expense amounted to $50 and
$314 for the year ended December 31, 1996 and the nine month period ended
September 30, 1997, respectively. The agreement requires an annual commitment
fee of approximately $28.
 
     At December 31, 1996 and September 30, 1997, irrevocable letters of credit
of $500 and $1,000, respectively, were issued under this agreement which are
being maintained as security for performance under long-term property lease
agreements.
 
     At September 30, 1997, amounts available under the secured line of credit
were $2,479.

BRIDGE FINANCING
 
     In March 1997, the Company obtained a $1,000 unsecured bridge loan which
bore interest at a rate of 10% per annum from a holder of the Series A
Preferred. The terms of the loan provided for a rate of interest of 10% per
annum through June 30, 1997 and 18% per annum from July 1, 1997, payable
monthly. The loan was payable upon demand by the holder at any time after the
earliest of the following to occur: (i) the closing of initial public offering
in the amount of $8,000 or greater, (ii) the closing of a private placement of
any class of the Company's capital stock equal to or exceeding $8,000, (iii) a
'Disposal Event' as defined by the loan agreement, or (iv) September 30, 1997.
 
     The loan agreement also provided that upon completion of a public offering
or private placement equal to or exceeding $8,000, the holder of the loan had
the option to convert the outstanding principal amount of the note and accrued
and unpaid interest into the class of capital stock issued in the public or
private offering. In May 1997 the holder of the loan converted the loan plus
accrued interest thereon, in the amount of $20, into 10,200 shares of Series B
Preferred.
 
     In further consideration of the loan, upon completion of the Series B
Preferred financing, the Company issued a warrant to the Series A Preferred
holder to purchase 41,511 shares of common stock at an initial exercise price of
$6.02 per share. The warrant is exercisable for a period of ten years from the
date of issuance. The fair value of the warrant, in the amount of $103, has been
recorded as additional paid-in capital.
 
6. COMMON STOCK AND CONVERTIBLE PARTICIPATING PREFERRED STOCK
 
COMMON STOCK SPLIT, INCREASE IN AUTHORIZED COMMON SHARES AND CHANGE TO PAR VALUE
OF COMMON STOCK
 
     Effective May 30, 1997, the Company implemented a six-for-one stock split
applicable to all issued and outstanding shares of the Company's common stock
and increased the number of authorized shares of common stock from 10,000,000 to
50,000,000. In addition, the par value of the Company's common stock was changed
from $.01 per share to $.001 per share.
 
SERIES A CONVERTIBLE PARTICIPATING PREFERRED STOCK
 
     In January 1996, the Company issued 422,607 shares of Series A Preferred at
$23.33 per share providing gross proceeds of $9,859 and net proceeds, after
deducting expenses, of $9,389. Each share of Series A Preferred is convertible
at the option of the holder into the number of shares of common stock determined
by dividing $23.33 by the conversion price. The initial conversion price was
$10.70, which is subject to adjustment to the share price of any security
issuances at a per share price lower than $10.70 prior to the second anniversary
of the date of issuance of the Series A Preferred stock. Subsequent to the
second anniversary of the issuance of the Series A Preferred the Series A shares
are subject to weighted average anti-dilution provisions. Upon issuance of the
initial Series B Preferred on May 30, 1997 (See below), the conversion price of
the Series A Preferred was adjusted to $6.02 per share. The Series A Preferred
shares will automatically convert into common stock upon the consummation of a
public offering of the Company's common stock with gross proceeds and a per
share price of qualifying amounts.
 
     At any time after the fifth anniversary of the date of issuance of the
Series A Preferred, a holder, at their option, may sell such shares to the
Company at a redemption price of $23.33 per share plus a redemption premium
equal to $1.40 per annum accruing from the date of issuance to the redemption
date, less any dividends paid thereon prior to the redemption date and including
the amount of any dividends or other distributions declared but unpaid on the
Series A Preferred. The Series A Preferred will have an aggregate redemption
value of $12,817 at January 30, 2001, the earliest date at which

redemption may be required. The excess of the redemption value over the carrying
value is being recorded by periodic charges to stockholders' equity through the
earliest date at which the Series A Preferred holders may require redemption of
the Series A Preferred.
 
     The holders of Series A Preferred are entitled to vote on matters which
holders of common stock have the right to vote.
 
     In connection with this transaction, the Company issued a warrant for the
purchase of 15,542 shares of the Company's common stock, at an initial exercise
price of $0.03 per share, as a placement fee to a financial advisor. The fair
value of the warrant in the amount of $166 has been recorded to additional
paid-in capital. The warrant is exercisable for a period of ten years from the
date of issuance.
 
10% PIK SERIES B CONVERTIBLE PARTICIPATING PREFERRED STOCK
 
     On May 30, 1997, the Company issued and sold 100,000 shares of the Series B
Preferred at $100.00 per share providing gross proceeds of $10,000 and net
proceeds, after deducting expenses, of $9,601. Subsequent to the initial
issuance, and prior to the first anniversary of the closing date, subject to
certain closing conditions, the Company has the option to issue and sell up to
an additional 50,000 shares to the original investors at a price per share of
$100.00. As of September 30, 1997, the Company has not exercised this option.
This option lapses upon the closing of an initial public offering by the
Company. In connection with this transaction, the Company issued a warrant for
the purchase of 838,199 shares of the Company's common stock, at an initial
exercise price of $6.02 per share, to the original investors of the Series B
Preferred. The warrant is exercisable for a period of ten years from the date of
issuance. The fair value of the warrant, in the amount of $1,958, has been
recorded as additional paid-in capital.
 
     The holders of the Series B Preferred have the right to convert such shares
into common stock at an initial conversion rate of $100.00 divided by a
conversion price of $6.02 per share. In the event the Company exercises its
option to sell the additional 50,000 shares of Series B Preferred to the
original investors, the conversion price will be amended to $4.51 per share. In
addition: (i) such shares will automatically convert into common stock upon the
consummation of a public offering or sale transaction of qualifying size of the
Company's common stock, (ii) any time after the fifth anniversary of the date of
issuance of the Series B Preferred, a holder at its option may sell such shares
to the Company at a redemption amount, and (iii) in the event of a liquidation
of the Company the holders of the Series B Preferred are entitled to a senior
liquidation preference (each as defined).
 
     An in-kind dividend will accrue at an annual rate of 10%. The excess of
redemption value over carrying value, is being recorded by periodic charges to
stockholders' equity through May 30, 2002, the earliest date the Series B
Preferred holders may require redemption of the Series B Preferred. The Series B
Preferred will have an aggregate redemption value of $16,530 at May 30, 2002.
The holders of Series B Preferred shall participate equally per share in any
dividends to holders of common stock or the Series A Preferred in excess of an
annual rate of 10% and shall be entitled to vote on matters which holders of
common stock have the right to vote.
 
     Also in connection with the initial issuance of Series B Preferred, the
Company issued a warrant to a financial advisor for the purchase of 50,042
shares of common stock at an exercise price of $0.03 per share. The fair value
of the warrant, in the amount of $301, has been recorded to additional paid-in
capital.
 
     Prior to the initial issuance of the Series B Preferred, the original
Series B Preferred investors advanced amounts to the Company in the form of
bridge loans totaling $5,750 bearing interest at an annual rate of 10%. Such
advances were repaid with interest in the amount of $16, upon the closing of the
initial issuance of the Series B Preferred.

     During the period from July 1997 to September 1997, the Company issued and
sold an additional 70,040 shares of the Series B Preferred at $100.00 per share,
providing gross proceeds of $7,004 and net proceeds, after deducting expenses,
of $6,907.
 
7. TRANSACTIONS WITH RELATED PARTIES
 
     On July 17, 1995, the three founders and principal stockholders of the
Company entered into an agreement whereby, among other things, each of these
stockholders agreed to grant to the other two stockholders the right of first
refusal to purchase any shares of the Company's common stock they propose to
sell on substantially the same terms as a potential third-party is offering and,
upon their death, the right to purchase any or all of their shares of common
stock of the Company at the fair market value on the date of death.
 
     In August 1995, the Company made loans in the amount of $50 to each of its
three principal stockholders. The loans bear interest at a rate of 7% per annum.
Interest income from such loans amounted to $3, $14, and $8 for the years ended
December 31, 1995 and 1996 and the nine month period ended September 30, 1997,
respectively. The loans, and accrued interest thereon, are due on demand.
 
     On December 4, 1995, the Company entered into employment agreements with
each of its three principal stockholders and founders, which expire five years
from the date of the agreement. The employment agreements, which provide for
base salaries and guaranteed bonuses, contain certain non-compete clauses which
are in effect for a period of one year following termination of employment. In
the event of termination of employment of any of such principal stockholders
following a change in control (as defined in the employment agreements), that
has not been approved by the Board of Directors, the principal stockholders will
receive a termination payment equal to 2.99 times their respective base salary.
On June 2, 1997, the employment agreements were amended by the Company. As a
result of these amendments, the expiration dates of the agreements were extended
to May 29, 2002.
 
8. STOCK OPTION, DEFINED CONTRIBUTION AND PROFIT SHARING PLANS
 
STOCK OPTION PLANS
 
     In July 1995, the Company adopted a stock option plan (the 'July Plan')
which was subsequently terminated by the Company's Board of Directors on October
23, 1995. Pursuant to the July Plan, the Company granted certain employees
options to purchase 552,000 shares of the Company's common stock at $0.27 per
share. The Company recorded $133 of compensation expense during 1995 related to
the grant of such options. As of the date of grant, 65,455 options were
exercisable, and none were exercised prior to October 23, 1995, the date on
which the July Plan and all options granted pursuant thereto were canceled.
 
     On October 23, 1995, the Company implemented its 1995 Stock Option Plan
(the 'Plan'), whereby incentive and nonqualified options to purchase up to
1,090,909 shares of the Company's common stock may be granted to key employees,
directors and consultants. On March 14, 1997, the Board of Directors approved an
amendment to the Plan whereby the aggregate number of shares of common stock for
which options may be granted under the Plan was increased to 1,636,363. The
exercise and vesting periods and the exercise price for options granted under
the Plan are determined by a Committee of the Board of Directors. The Plan
stipulates that no option may be exercisable after ten years from the date of
grant. The fair market value of the Company's common stock is determined by the
Board of Directors. Options granted under the Plan generally vest in equal
installments over periods ranging from one to five years.

               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
     Under the Plan, each non-employee director, upon their initial appointment,
shall be granted options to purchase 3,273 shares of the Company's common stock
at a price equal to its fair market value at the date of grant. Additionally,
options to purchase 2,182 shares of the Company's common stock at the then fair
market value shall be granted immediately following each annual meeting of the
stockholders. These options are exercisable for five years from the date of
grant. No such options have yet been granted as of December 31, 1996 and
September 30, 1997.
 
     On June 18, 1997 outstanding employee stock options, with exercise prices
ranging from $6.42 to $14.27, to purchase 868,364 shares of common stock were
repriced at $6.02 per share, which was the fair market value as determined by

     The Company applies Accounting Principles Board Opinion No. 25 'Accounting
for Stock Issued to Employees,' and related interpretations in accounting for
its Plan and other stock-based compensation issued to employees and directors.
During the year ended December 31, 1996 and the nine months ended September 30,
1997, the Company was not required to recognize compensation expense for options
granted to employees.

     Had compensation cost for options grants to employees been determined based
upon the fair value at the date of grant for awards under the Plan consistent
with the methodology prescribed under Financial Accounting Standards No. 123,
'Accounting for Stock Based Compensation,' ('FAS 123'), the Company's net loss
for the years ended December 31, 1995 and 1996 and the nine months ended
September 30, 1997 would have increased by approximately $35, $529 and $401,
respectively.
 
     The fair values of options granted to employees during the years ended
December 31, 1995 and 1996 and the nine months ended September 30, 1997 has been
determined on the date of the respective grant using the Black-Scholes
option-pricing model based on the following weighted average assumptions:

DEFINED CONTRIBUTION AND PROFIT SHARING PLANS
 
     The Company has a defined contribution savings plan (the 'Plan'), which
qualifies under Section 401(k) of the Internal Revenue Code, for employees
meeting certain service requirements. Participants may contribute up to 10% of
their gross wages not to exceed, in any given year, a limitation set by Internal
Revenue Service regulations. The Plan provides for discretionary contributions
to be made by the Company as determined by the Company's Board of Directors. The
Company has not made any contributions to the Plan during periods presented. The
Company also has a profit sharing plan (the 'PSP') covering substantially all
full-time employees. Contributions by the Company to the PSP amounted to $129
and $28 in 1994 and 1996, respectively. There were no contributions to the PSP
during 1995 and the nine months ended September 30, 1997.
 
9. CONCENTRATION OF RISK AND CUSTOMER INFORMATION
 
     A significant percentage (49%, 58%, 68% and 62% in the years ended December
31, 1994, 1995 and 1996 and the nine months ended September 30, 1997,
respectively) of the Company's revenues are derived from domestic third-party
financial services companies. Financial instruments which potentially subject
the Company to concentrations of credit risk are primarily cash, accounts
receivable, notes receivable, accounts payable and short-term notes payable. The
Company generally does not require collateral and the majority of its trade
receivables are unsecured. The Company is directly affected by the well being of
the financial services industry; however, the Company does not believe
significant credit risk exists at September 30, 1997. The Company relies on
other companies to supply certain key components of its network infrastructure,
including telecommunications services and networking equipment, which, in the
quantities and quality required by the Company, are available only from a
limited number of sources. The Company is also dependent upon local exchange
carriers to provide telecommunications services to the Company and its
customers. There can be no assurance that the Company will be able to obtain
such services on the scale and within the time frames required by the Company at
an acceptable cost, or at all.
 
     The network-based information management systems sold by the Company are
provided by one manufacturer for whom the Company serves as a value-added
reseller. Termination or loss of the Company's agreement with this manufacturer
may have a material adverse impact on the Company's financial position and
results of operations.

                (UNAUDITED WITH RESPECT TO THE NINE MONTH PERIOD
                           ENDED SEPTEMBER 30, 1996)
               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
     For the years ended December 31, 1994, 1995 and 1996 and the nine months
ended September 30, 1997 a single customer accounted for 25%, 28%, 30% and 49%
of net revenues, respectively. For the years ended December 31, 1994, 1995 and
1996 a second customer accounted for 11%, 15% and 13% of net revenues,
respectively. For the year ended December 31, 1995 a third customer accounted
for 10% of net revenues.
 
10. INCOME TAXES
 
     The Company has incurred losses during 1995, 1996 and the nine months ended
September 30, 1997, which have generated net operating loss carryforwards of
approximately $15,272 at September 30, 1997, for federal and state income tax
purposes. These carryforwards are available to offset future taxable income and
expire in 2011 through 2012 for federal income tax purposes. At September 30,
1997 the Company also had research and development tax credit carryforwards in
the amount of $87 which expire in 2001. These losses and credits are subject to
limitation on future years utilization should certain ownership changes occur.
 
     The net operating loss carryforwards and temporary differences between
carrying amounts of assets and liabilities for financial reporting and income
tax purposes result in a net deferred tax benefit of $7,486 at September 30,
1997. The Company's operating plans anticipate taxable income in future periods;
however, such plans make significant assumptions which cannot be reasonably
assured including continued market acceptance of the Company's products and
services by customers. Therefore, in consideration of the Company's accumulated
losses and the uncertainty of its ability to utilize this deferred tax benefit
in the future, the Company has recorded a valuation allowance in the amount of
$7,486 at September 30, 1997, respectively, to offset the deferred tax benefit
amount.
 
     Significant components of the noncurrent deferred tax assets at December
31, 1994, 1995, 1996 and September 30, 1997 are as follows:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                (UNAUDITED WITH RESPECT TO THE NINE MONTH PERIOD
                           ENDED SEPTEMBER 30, 1996)
               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
OTHER
 
     In February 1997, the Company entered into an agreement to purchase
interexchange telecommunications services through February 29, 2000. Pursuant to
this agreement the Company has a monthy commitment, before discounts, of $50.
These purchase commitments are not expected to exceed usage requirements in any
of the months covered by the agreement.
 
     At September 30, 1997 trade payables to a vendor in the amount of $2,614
were secured by substantially all of the assets of the Company. The security
agreement is subordinated to the security interests of a lending institution in
connection with a secured line of credit (Note 5).
 
12. INITIAL PUBLIC OFFERING AND PRO FORMA PRESENTATION
 
     On October 16, 1997, the Board of Directors of the Company authorized
management to pursue an underwritten sale of shares of the Company's common
stock in an initial public offering (the 'IPO') pursuant to the Securities Act
of 1933. In connection with the IPO, on October 16, 1997 the Company's Board of
Directors approved a 1-for-2.75 reverse stock split to be applicable to all
issued and outstanding shares of the Company's common stock, which split became
effective on December 15, 1997. All common shares, stock options, warrants and
related per share data, reflected in the accompanying financial statements and
notes thereto, have been presented as if the stock split had occurred on January
1, 1994. In addition the Board of Directors has approved an increase in the
shares available for grant under the Plan from 1,636,364 to 2,181,818. Such
increase will be effective only upon completion of the initial public offering.
 
     Upon the closing of the IPO, all outstanding shares of Series A and Series
B Preferred Stock will automatically convert into an aggregate of 4,629,831
shares of common stock. The pro forma effects of this conversion have been
reflected in unaudited pro forma stockholders' equity at September 30, 1997 and
pro forma earnings per share for the year ended December 31, 1996 and the nine
months ended September 30, 1997.
 
     Upon consummation of the IPO, the agreement among the three founders and
principal stockholders of the Company (Note 7) will be terminated.

ITEM 14. INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS.
 
     Section 145 of the General Corporation Law of Delaware provides that
directors, officers, employees or agents of Delaware corporations are entitled,
under certain circumstances, to be indemnified against expenses (including
attorneys' fees) and other liabilities actually and reasonably incurred by them
in connection with any suit brought against them in their capacity as a
director, officer, employee or agent, if they acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests of
the corporation, and with respect to any criminal action or proceeding, if they
had no reasonable cause to believe their conduct was unlawful. Section 145 also
provides that directors, officers, employees and agents may also be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
them in connection with a derivative suit bought against them in their capacity
as a director, officer, employee or agent, as the case may be, if they acted in
good faith and in a manner they reasonably believed to be in or not opposed to
the best interests of the corporation, except that no indemnification may be
made without court approval if such person was adjudged liable to the
corporation.
 
     Article Eleventh of the Restated Certificate of Incorporation provides that
the registrant shall indemnify any and all persons to the fullest extent
permitted by the General Corporation Law of Delaware.
 
     Section 7 of the Underwriting Agreement (Exhibit 1.1) provides for
indemnification by the underwriters of the Selling Stockholders for certain
liabilities, including certain liabilities under the Securities Act of 1933,
under certain circumstances.
 
     The Company maintains a directors and officers liability insurance policy
with Rock River Insurance Company. The policy insures the directors and officers
of the Company against loss arising from certain claims made against such
directors or officers by reason of certain wrongful acts. The policy provides
combined limit of liability of $5,000,000 per policy year for both directors'
and officers' liability coverage at an annual premium of $90,000.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     (a) On May 30, 1997, the registrant effected a 6 for 1 stock split of its
Common Stock. For each share of Common Stock outstanding on May 30, 1997, the
holder thereof received six shares of Common Stock.
 
     (b) In January 1996, the Company sold 422,607 shares of Series A
Convertible Participating Preferred Stock, par value $.01 per share ('Series A
Preferred Stock'), at $23.33 per share, each of which is convertible into shares
of Common Stock at a price of $6.02 per share, and issued between
 
                                      II-1
 

<PAGE>

Stock at an exercise price of $6.02 per share and 52,544 shares of Common Stock

     The issuance of securities set forth in (a) above is believed by the

reliance upon Section 3(a)(9) of such Act. The issuance of securities set forth
in (b) above is believed by the registrant to be exempt from registration in

     The following financial statement schedule of the registrant is filed
herewith:
 
        (b) SCHEDULE
 
     Schedule II -- Valuation and Qualifying Accounts
 
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 requested by the underwriters to
permit prompt delivery to each purchaser.
     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 the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
     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 of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
