                               PROSPECTUS SUMMARY

     You should read the following summary together with the more detailed
information about us, the common stock we are selling in this offering and our
consolidated financial statements, including the notes to those statements,
included elsewhere in this prospectus.

                                  OUR BUSINESS

     We are a business-to-business intermediary that facilitates the buying and
selling of capacity on communications networks. We facilitate the process
through which users of communications circuits obtain circuits dedicated for
their specific use from multiple vendors. We refer to this process as
"provisioning a circuit." We also facilitate the installation and servicing of
these dedicated circuits. Our clients are communications service providers, such
as telecommunications service providers, internet service providers and
application service providers, who buy capacity on communications circuits for
use by their customers. We obtain the communications capacity from transport
suppliers, who are the owners of the communications infrastructure over which
information is transmitted.

     Through our services, we provide our clients with an outsourced, integrated
solution to obtaining communications network capacity within a fragmented
network services market. The services we provide include:

     - assembling detailed information about available network capacity from
       multiple suppliers;

     - operating facilities where communications networks can be physically
       interconnected;

     - providing ongoing access to dedicated circuits; and

     - providing client support services.

     We offer our clients the ability to obtain pricing quotes and circuit
availability information and to order circuits over the Internet. We intend to
expand our Internet service offering to include network management, monitoring
and restoration. Through these services, we provide our clients with an
outsourced, integrated solution to the challenges they face within a fragmented
network services market.

     As an independent intermediary, we have been able to collect and assemble
network information from multiple transport suppliers. Our Universal Information
Exchange, or UIX, consists of several proprietary, interconnected databases
containing capacity, availability, physical location and pricing information
from over 35 transport suppliers and more than 75,000 physical sites. Through
our UIX we efficiently and cost-effectively provide our clients with dedicated
circuits that connect across the networks of multiple suppliers. In addition, we
operate network interconnection facilities called Universal Transport Exchanges,
or UTXs, where various transport suppliers can easily connect to the networks of
any other transport supplier in that facility. We also provide a single point of
contact for network management services, including network monitoring,
maintenance and restoration.

     As of December 31, 1999, we provided services to over 100 clients,
including AboveNet Communications (MFN), BCE Nexxia, Cable & Wireless, Teleglobe
Communications and UUNET, each of which represented at least 1% of our monthly
recurring revenues as of December 31, 1999.

                                THE OPPORTUNITY

     The communications network services market is competitive, complex and
fragmented. Domestic and international deregulation, combined with growth in
Internet usage, has spawned a rapid increase in the number of transport
suppliers and service providers as well as the strategies they employ to build
networks and reach customers. This diversity of industry participants and
business strategies has resulted in the development of multiple networks serving
various geographic regions. It is difficult to connect these networks together
due to the fact that transport suppliers and service providers do

                                        3
<PAGE>   6

not have access to pricing, capacity, availability and location information for
the networks of other suppliers. Because transport suppliers compete with each
other, they have little incentive to share this information or to locate their
equipment within competitors' facilities. To date, we believe that major
transport suppliers have not been able to effectively support dedicated circuits
that connect across the networks of multiple suppliers on their own networks, or
through efficient interconnection with other suppliers, to fully meet their
customers' requirements.

     Communications service providers and transport suppliers face a number of
challenges, as outlined below, due to the number of vendors in the market.

<S>                                             <C>
- - significant time and expense related to       - inability to efficiently fulfill customer
  pricing, obtaining and installing               demand for dedicated circuits due to the
  circuits;                                       limited coverage of their networks;
- - difficulty determining the availability of    - costs associated with selling excess
  capacity in a timely manner, which may          network capacity; and
  result in significant backlog of customer     - inability to provide a consistent level of
  orders and possibly lost revenues; and          service over multiple network segments.
- - inability to maintain, monitor and restore
  connections.
</TABLE>

                                  OUR SOLUTION

     Our integrated solution addresses these challenges and provides the
following key benefits to our clients:

     - Single Point of Contact for Supplying and Installing Circuits and
       Providing Network Management Services. As a third-party provider, we
       allow our clients to outsource the obtaining, installing and providing of
       their communications infrastructure. Our solution provides significant
       time, effort and cost savings to our clients who would otherwise be
       forced to independently analyze the capacity, availability and pricing of
       circuits from multiple vendors to construct and maintain circuits. In
       addition, we maintain a network management service organization through
       which we provide a single point of contact for 24-hour-a-day,
       seven-day-a-week network monitoring, maintenance and restoration across
       multiple vendor networks.

     - Efficient, Cost Effective Provision and Installation of Circuits Across
       Multiple Vendor Networks. We use the information contained in our UIX
       databases to efficiently and cost-effectively provide and install
       circuits across geographically dispersed, multiple vendor networks.

     - Easily Extended Network Coverage. Our clients are able to easily extend
       the coverage of their networks by purchasing dedicated circuits from us
       which access the networks of over 35 network transport suppliers.

     - Significant Source of Demand for Transport Capacity Suppliers. We
       represent a significant source of demand for transport suppliers because
       we purchase a large volume of circuits. We believe our transport
       suppliers consider us to be a valuable partner because we provide them
       efficient access to the capacity requirements of our clients.

     - Ongoing Client Support. We provide ongoing technical and administrative
       support during the circuit planning, ordering, provisioning and
       installation processes.

                                  RISK FACTORS

     An investment in our common stock involves a high degree of risk. Before
you invest in our common stock, you should consider carefully the risks
described below, together with all of the other information included in this
prospectus. If any of the risks described below were to occur, our business,
financial condition and results of operations could be materially adversely
affected. In that case, the trading price of our common stock could decline and
you could lose part or all of your investment.

IF WE FAIL TO INCREASE OUR REVENUES, WE WILL BE UNABLE TO ACHIEVE AND MAINTAIN
PROFITABILITY.

     We have incurred significant losses since inception and expect to continue
to incur losses in the future. As of December 31, 1999, we had an accumulated
deficit of $23.0 million. Although our revenues have grown from $899,000 in the
quarter ended December 31, 1998 to $5.7 million in the quarter ended December
31, 1999, we cannot be certain that our revenues will continue to grow, or that
we will achieve sufficient revenues to achieve profitability. We expect to
continue to incur significant and increasing expenses in order to:

     - expand sales and marketing activities to increase market acceptance;

     - expand our operational activities to further develop our business model;

     - expand our administrative organization to support the anticipated growth
       of our business;

     - expand and enhance our UIX databases; and

     - build out our UTX facilities.

     As a result, we will need to generate significantly higher revenues to
achieve and maintain profitability. If we fail to generate higher revenues, we
may continue to incur operating losses and net losses.

OUR LIMITED OPERATING HISTORY MAKES FORECASTING DIFFICULT.

     We have a limited operating history and, therefore, limited meaningful
historical financial data upon which to base our planned operating expenses.
Specifically, our UTX business model is relatively new, and we have not operated
our UIX databases in conjunction with our UTX facilities long enough to
accurately predict trends in our business. Moreover, we have not built out
enough UTX facilities to be able to test whether our strategy to utilize these
facilities will work. Accordingly, we are subject to all of the risks that are
associated with companies in an emerging industry and in an early stage of
development, including:

     - undercapitalization;

     - cash shortages;

     - the unproven nature of our business model;

     - the new and unproven nature of the market for our services;

     - the need to make significant expenditures and incur significant expenses
       as we develop our business, infrastructure and operations;

     - the lack of sufficient clients and revenues to sustain our operations and
       growth without additional financing;

     - difficulties in managing growth; and


     - limited experience in providing some of the services that we offer or
       plan to offer.



     For example, from time to time we enter into long-term agreements with
communications transport suppliers for the supply and installation of
communications network capacity. These

                                        8
<PAGE>   11


agreements generally provide for monthly minimum revenue commitments from us,
which we must negotiate based on forecasts of our future network capacity
requirements. As of March 10, 2000, we were party to contracts that will impose
minimum purchase commitments that we anticipate will total approximately $1.8
million per month by September 2000. If we fail to forecast our network capacity
requirements accurately or fail to accurately forecast other aspects of our
business, it will be difficult for us to become profitable, and you may lose
part or all of your investment.


WE HAVE AN UNPROVEN BUSINESS MODEL, AND WE CANNOT BE SURE THAT CLIENTS WILL
WIDELY ACCEPT OUR SERVICES.

     Our business strategy is unproven. To be successful, we must convince
prospective clients to entrust their network capacity data and transport
requirements to a company without a long and proven track record. We are not
aware of any companies that have a directly comparable business, and we cannot
be sure that clients will widely accept our services.

     Our ability to expand our client base may be limited by the following
factors:

     - the speed, reliability and cost effectiveness of our services;

     - the willingness of clients to outsource the obtaining of circuits;

     - our ability to market our services effectively; and

     - the growth of the Internet.

     We may not be able to execute our business model if the markets for our
services fail to develop or grow more slowly than anticipated, if competitors
enter the market or if we are unable to expand our client base.

OUR ABILITY TO IMPLEMENT AND MAINTAIN OUR UIX DATABASES IS UNPROVEN. IF WE
CANNOT INCREASE THE SCOPE AND ACCURACY OF THESE DATABASES AS PLANNED, OUR
ABILITY TO COST-EFFECTIVELY FACILITATE THE OBTAINING OF CIRCUITS FOR OUR CLIENTS
WILL BE AT RISK.

     To be successful, we must increase and update information about pricing,
capacity, availability and location of circuits contained in our databases. Our
ability to cost effectively facilitate the supplying of circuits and to provide
ongoing dedicated line circuit access depends upon the information we collect
from our transport suppliers regarding their networks, which we include in our
UIX databases. Our suppliers are not obligated to provide us with this
information and could decide to stop providing this information to us at any
time. Moreover, we cannot be certain that the information that our suppliers
share with us is completely accurate or current. If we cannot continue to
maintain and expand our UIX databases as planned, we may be unable to increase
our revenues or to cost-effectively facilitate the supplying of the circuits,
and we may never achieve profitability.

THE MARKET FOR OUR UTX SERVICES IS NEW AND UNPROVEN, AND WE HAVE LIMITED
EXPERIENCE PROVIDING OUR UTX SERVICES.

     The market for our UTX services is new and unproven. Our ability to
generate revenues will suffer if the market for these services fails to develop,
or develops more slowly than we expect. The growth of this market depends on
several uncertain events or occurrences including:

     - our ability to remain a neutral intermediary between transport suppliers
       and the willingness of these suppliers to install their equipment in our
       UTX facilities;

     - our ability to successfully and cost-effectively market our services to a
       sufficiently large number of clients; and

     - the increased need for high speed communications network services.

                                        9
<PAGE>   12

     To date, we have derived substantially all of our revenues from providing
on-going circuit access, and we have only limited experience providing our UTX
services. At March 7, 2000, we had two operational UTX sites and seven UTX
clients. However, these clients may terminate their UTX contracts at any time,
and our ability to generate revenues will suffer if we fail to maintain our
existing clients and to attract new clients for our UTX services.

CONSTRUCTION OF UTX FACILITIES IS EXPENSIVE AND TIME-CONSUMING AND WILL CAUSE A
SIGNIFICANT STRAIN ON THE CAPITAL RESOURCES AND OPERATION OF OUR BUSINESS.

     One of our key strategies is to expand our business by opening additional
UTX facilities in geographically diverse locations. As of December 31, 1999 we
had operational UTX facilities in Chicago and Santa Clara and UTX facilities
under construction in San Francisco, Los Angeles, Miami, Dallas and Washington,
D.C. We expect to begin the construction of eight additional UTX facilities in
the United States in 2000.

     If we are unable to generate sufficient cash flows or raise sufficient
funds, we may have to delay or abandon some or all of our development and
expansion plans. A delay in the expansion of our UTX facilities may make it more
difficult for us to respond to competitive pressures and establish our presence
in the market.

     It usually takes us at least six months to select an appropriate location
for a new UTX facility, construct the facility, install equipment and
communications network infrastructure and hire operations and sales personnel.
We must incur these costs before we have clients who purchase our services to be
delivered from the UTX facilities. If the demand does not develop as we
anticipate, we will have fixed costs without corresponding revenue and our
business will be harmed. Once a UTX facility becomes operational, we expect it
to experience losses for at least one year.

     Our ability to open UTX facilities is subject to a number of risks,
including the following:

     - the availability of appropriate space for these facilities on reasonable
       terms;

     - competition for limited space in desirable locations from large,
       well-capitalized companies that may be more attractive tenants for
       potential landlords;

     - construction delays;

     - cost overruns;

     - equipment and material delays; and

     - inability to obtain necessary permits on a timely basis.

     In addition, our costs will increase as we open additional UTX facilities.
These increased costs include:

     - leasing additional real estate;

     - expenses associated with hiring, training and managing new employees;

     - purchasing new equipment;

     - implementing power and redundancy systems;

     - implementing multiple communications connections; and

     - depreciation expense.

     An inability to establish additional UTX facilities as planned, to
effectively manage our expansion or to attract sufficient clients to our UTX
facilities would harm our ability to generate revenues.

                                       10
<PAGE>   13

IF WE CANNOT SUCCESSFULLY IMPLEMENT OUR NETWORK OPERATIONS CENTER, WE WILL BE
UNABLE TO PROVIDE MONITORING, MAINTENANCE AND RESTORATION SERVICES TO OUR
CLIENTS.

     One of our primary business objectives is to provide our clients with
network monitoring, maintenance and restoration services 24 hours a day, seven
days a week through a network operations center. However, we have not fully
developed this capacity and currently provide network management services
through an outsourcing arrangement with a third party, until our own facility
becomes operational. We recently acquired a network operations facility, but
have not yet upgraded this facility or begun hiring employees, and we have only
limited experience implementing services of this type. As a consequence, we
cannot be sure that our efforts to provide these services will be successful.
Our ability to implement this strategy will depend on many factors, including
our ability to upgrade the facility, install new equipment and hire, train and
manage employees.

     If we fail to successfully implement a network operations center, we may
not be able to monitor network operations effectively or troubleshoot circuits
in a cost-effective manner, which would cause us to lose clients and make it
difficult for us to attract new clients.

ALTHOUGH WE PLAN TO EXPAND INTERNATIONAL OPERATIONS, WE HAVE NO EXPERIENCE
OPERATING INTERNATIONALLY.

     An important component of our strategy is to expand into international
markets, such as Europe, Asia and South America. However, we have no experience
operating internationally. The risks inherent in conducting our business
internationally include:

     - unexpected changes in regulatory requirements and trade barriers;

     - unexpected changes in national and international (including European
       Union and World Trade Organization) regulatory requirements and trade
       barriers;

     - challenges in staffing and managing foreign operations;

     - differences in technology standards;

     - employment laws and practices in foreign countries;

     - longer payment cycles and problems in collecting accounts receivable;

     - inability to obtain access to transport capacity;

     - political instability;

     - fluctuations in currency exchange rates and imposition of currency
       exchange controls; and

     - potentially adverse tax consequences.

     In addition, in order to expand internationally, we may enter into joint
ventures or outsourcing agreements with third parties, acquire complementary
businesses or operations, or establish and maintain new operations outside of
the United States. We may not control or manage some or all of these operations.
As a result, we may be required to depend on third parties for the management of
these international operations. If these foreign operations are not successful,
they could significantly damage our reputation, which would harm our ability to
attract new clients and retain existing clients.

COMPETITION IN OUR INDUSTRY IS INTENSE AND GROWING, AND WE MAY BE UNABLE TO
COMPETE EFFECTIVELY.

     The market for the services we provide is highly fragmented. In addition,
the market in which we operate is new, rapidly evolving and highly competitive.
We believe that at this time no single competitor competes directly with us with
respect to all of the services we offer; however, we

                                       11
<PAGE>   14

currently or potentially compete with a variety of companies, including some of
our transport suppliers, with respect to our products and services individually,
including:

     - national and local carriers, such as AT&T, Broadwing, MCI WorldCom and
       Williams Communications;

     - companies that provide collocation facilities, such as AboveNet
       Communications (MFN), AT&T, Equinix, Exodus Communications, Frontier
       Global Center, and Intel;

     - competitive local exchange carriers, such as AT&T, ELI, ICG
       Communications, MCI WorldCom, NextLink Communications, and Pathnet; and

     - incumbent local exchange carriers, such as GTE and Sprint, and regional
       Bell operating companies such as BellSouth and SBC Communications.

     We expect to face additional competition from new market entrants in the
future as there are few substantial barriers to entry in our market. Significant
new competitors could arise from increased consolidation and strategic alliances
in the telecommunications industry. Other new entrants could enter the market
with a business model similar to ours. Our target markets may support only a
limited number of competitors. Operations in such markets with multiple
competitive providers may be unprofitable for one or more of such providers.
Prices in both the long distance business and the data transmission business
have declined significantly in recent years and are expected to continue to
decline.

     Moreover, while recent regulatory initiatives allow carriers such as us to
interconnect with incumbent local exchange carrier facilities and to obtain
unbundled network elements from incumbent local exchange carriers, certain
initiatives also provide increased pricing flexibility for, and relaxation of
regulatory oversight of, the incumbent local exchange carrier. This may present
incumbent local exchange carriers with an opportunity to subsidize services that
compete with our services with revenues generated from non-competitive services.
This would allow incumbent local exchange carriers to offer competitive services
at lower prices. Existing laws also restrict the regional Bell operating
companies from fully competing with us in the market for interstate and
international long distance telecommunications services, but also permit the
Federal Communications Commission, the FCC, to lessen or remove some
restrictions. If FCC decisions under existing law, or future amendments to
Federal telecommunications laws, permit the regional Bell operating companies to
compete fully with us in this market, our revenues from these services could be
reduced if these companies are able to attract a substantial portion of our
customers.

     We must distinguish ourselves through the quality of our client service,
our service offerings and brand name recognition. We may be unsuccessful in
doing this.

     Many of our potential competitors have certain advantages over us,
including:

     - substantially greater financial, technical, marketing and other
       resources, including brand or corporate name recognition;

     - larger customer bases;

     - longer operating histories; and

     - more established relationships in the industry.

     Our competitors may be able to use these advantages to:

     - expand their offerings more quickly;

     - adapt to new or emerging technologies and changes in customer
       requirements more quickly;

     - take advantage of acquisitions and other opportunities more readily;

     - enter into strategic relationships to rapidly grow the reach of their
       networks and capacity;

                                       12
<PAGE>   15

     - devote greater resources to the marketing and sale of their services; and

     - adopt more aggressive pricing and incentive policies, which could drive
       down margins.

     If we are unable to compete successfully against our current and future
competitors, our gross margins could decline and we could lose market share,
either of which could materially and adversely affect our business.

IF WE HAVE DIFFICULTIES OR DELAYS IN DELIVERING CIRCUITS TO OUR CLIENTS, OUR
ABILITY TO GENERATE REVENUE WILL SUFFER AND WE MAY LOSE EXISTING AND POTENTIAL
NEW CLIENTS.

     It typically takes 30 to 90 days to supply a circuit for a client, and we
do not begin to recognize revenue until a circuit has been installed and
accepted by the client. Once we agree to facilitate the supply of a circuit for
a client, we negotiate with one or more transport suppliers and manage the
personnel and field technicians of multiple vendors. A client can withdraw its
order with minimal liability at any time before accepting the circuit. We may
experience difficulties in facilitating the supply of circuits if our transport
suppliers run out of capacity, forcing us to look for alternative sources of
capacity at the last minute. If we are unable to facilitate the supply of a
circuit in a timely manner or fail to obtain client acceptance of the circuit,
we will be unable to recognize access revenues for that circuit, and our
operating results would be adversely affected. Furthermore, the ability of our
clients to cancel orders at any time before accepting the circuit may make it
difficult for us to forecast revenue and plan our expenses accordingly.

THE UNPREDICTABILITY OF OUR QUARTERLY RESULTS MAY ADVERSELY AFFECT THE TRADING
PRICE OF OUR COMMON STOCK.

     Our revenues and operating results will vary significantly from quarter to
quarter due to a number of factors, many of which we cannot control and any of
which may cause our stock price to fluctuate. These factors include the
following:

     - uncertainty regarding timing for supplying circuits or failure to obtain
       client acceptance of circuits;

     - timing of the completion of new UTX facilities;

     - decisions by end-users to reallocate their information resources to other
       purposes, including year 2000 preparedness;

     - costs related to acquisitions of technology or businesses;

     - decisions by existing clients not to renew services on a timely basis
       when existing client contracts terminate;

     - the amount of unused circuit capacity that we hold;

     - general economic conditions as well as those specific to the Internet and
       related industries; and

     - Internet growth and demand for Internet infrastructure.

     In addition, we depend on decisions by our clients to expand their Internet
infrastructure, which decisions in turn depend upon the success and expected
demand for the services these clients offer.

     We expect our operating expenses to increase significantly in future
periods. Our operating expenses are largely based on anticipated revenue trends,
and a high percentage of our expenses are, and will continue to be, fixed in the
short term due in large part to our construction of our UTX facilities. As a
result, fluctuations in our revenue for the reasons set forth above, or for any
other reason, could cause significant variations in our operating results from
quarter to quarter and could result in substantial operating losses.

                                       13
<PAGE>   16

     Because of these factors, we believe that quarter-to-quarter comparisons of
our operating results are not, and will not be, a good indication of our future
performance. It is likely that, in some future quarters, our operating results
may not meet the expectations of public market analysts and investors. In that
event, the price of our common stock may fall.

OUR FACILITIES AND THE NETWORKS ON WHICH WE DEPEND MAY FAIL, WHICH WOULD
SERIOUSLY HARM OUR BUSINESS.

     Our clients depend on our ability to provide ongoing dedicated circuit
access. The operation of these circuits depends on the networks of third party
transport suppliers, such as MCI WorldCom or Williams Communications. The
networks of transport suppliers and clients who may use our UTX facilities, may
be interrupted by failures in or damage to these facilities. Our facilities and
the ongoing circuit access we provide may be interrupted as a result of various
events, many of which we cannot control, including:

     - fire;

     - human error;

     - earthquakes, floods and other natural disasters;

     - train derailments or similar disasters along communications
       rights-of-way;

     - power loss;

     - telecommunications failures; or

     - sabotage or vandalism.

     We may be subject to legal claims and be liable for losses suffered by our
clients for disruptions to circuits or damage to client equipment resulting from
failures at our facilities or on the networks of third party providers. In
addition, we may be subject to legal claims and be liable for losses suffered by
clients and carriers who use our UTX facilities. Our contracts with our clients
and with carriers who use our UTX facilities attempt to eliminate our liability
for consequential or punitive damages and for damage to client equipment not
caused by our gross negligence or willful acts. However, those provisions may
not protect us from being held liable for those damages.

     We generally provide outage credits to our clients if circuit disruptions
occur. If our circuit failure rate is high, we may incur significant expenses
related to circuit outage credits, which would reduce our revenues. We would
also have to incur significant expenses in investigating and addressing the
causes of such circuit failures, which would divert resources from the expansion
of our services and cause our business to suffer. Clients may seek to terminate
their contracts with us if there is a circuit failure. In addition, if our
circuit failure rate is high, our reputation could be harmed, which would make
it difficult for us to retain and attract clients.

WE DEPEND ON SEVERAL LARGE CLIENTS, AND THE LOSS OF ONE OR MORE OF THESE
CLIENTS, OR A SIGNIFICANT DECREASE IN TOTAL REVENUES FROM ANY OF THESE CLIENTS,
COULD SIGNIFICANTLY REDUCE OUR REVENUE AND INCOME.

     Historically, a substantial portion of our revenues has come from a limited
number of clients. For example, for the year ended December 31, 1998 two clients
accounted for approximately 29% of our total revenues, and for the year ended
December 31, 1999, one client accounted for approximately 38% of our total
revenues. We have a number of significant revenue contracts with this customer.
These contracts expire on various dates between May 2000 and April 2007.

     If we lose one or more large clients, or if one or more of our large
clients reduces the services they purchase from us and we fail to add new
clients, our revenues could decline and our results of operations would suffer.

                                       14
<PAGE>   17

OUR CLIENTS MAY FAIL TO PAY OR BE UNABLE TO PAY THEIR OBLIGATIONS TO US IN A
TIMELY MANNER OR AT ALL.

     Some of our clients may have limited operating histories and may have
inadequate financial resources to meet all of their obligations. We recorded a
substantial bad debt expense during the year ended December 31, 1999 primarily
in connection with the failure by one of our clients to pay its bills. If other
of our clients are unable to meet their obligations to us, we may incur
additional bad debt expenses, which could harm our cash flows and results of
operations.

THE REGULATORY FRAMEWORK UNDER WHICH WE OPERATE AND NEW REGULATORY REQUIREMENTS
OR NEW INTERPRETATIONS OF EXISTING REGULATORY REQUIREMENTS COULD REQUIRE
SUBSTANTIAL TIME AND RESOURCES FOR COMPLIANCE, WHICH COULD MAKE IT DIFFICULT FOR
US TO OPERATE OUR BUSINESS.

     Our communications services are subject to both federal and state
regulation. In providing our interstate and international communications
services, we must comply with federal telecommunications laws and regulations
prescribed by the FCC. At the state level, we are subject to state laws and to
regulation by state public utility commissions. As we expand internationally, we
will also become subject to regulation by foreign authorities and, in some
markets, supra-national authorities, such as the European Union.

     These laws and regulations are subject to frequent changes and different
interpretations, and therefore, it is difficult for us to assess the impact of
these factors on our operations. The current domestic and international trend is
toward deregulation of telecommunications and Internet services. However, we
cannot assure you that this trend will continue, and it is possible that changes
in regulatory policies could limit our ability to compete in some markets. The
implementation, modification, interpretation and enforcement of laws and
regulations vary and can limit our ability to provide many of our services.

     We will need to obtain authorization from the FCC and many state public
utilities commissions to offer particular types of telecommunications services.
Once we receive this authorization, we will have to comply with a variety of
regulatory obligations on an ongoing basis. We cannot assure you that the FCC or
state commissions will grant the required authority (or do so in a timely
manner), or refrain from taking action against us if we are found to have
violated any requirements of their rules. If authority is not obtained or if our
schedules of prices, terms, and conditions are not filed, or are not updated, or
otherwise do not fully comply with the rules of the FCC or state regulatory
agencies, third parties or regulators could challenge our ability to offer our
services. Such challenges could cause us to incur substantial legal and
administrative expenses.

     For additional information on governmental regulations affecting us, see
"Business -- Governmental Regulation."

REQUIRED REGULATORY APPROVALS MAY INTERFERE WITH OR DELAY CORPORATE
TRANSACTIONS.

     As a regulated company, we are required to obtain the approval of the FCC
and certain state regulators before engaging in certain types of transactions,
including mergers, acquisitions of other regulated companies, sales of all or
substantial parts of our business, issuance of stock, and incurrence of debt
obligations. The particular types of transactions that require approval differ
in each jurisdiction. In several states, any transaction that results in a
transfer of 10% or more of our voting stock may require prior approval. If we
cannot obtain the required approvals, or if we encounter substantial delays in
obtaining them, we may not be able to enter into transactions on favorable terms
and our flexibility in operating our business will be limited. If our
flexibility is limited, we may not be able to optimize our operating results.

                                       15

TELECOMMUNICATIONS REGULATIONS OF OTHER COUNTRIES MAY RESTRICT OUR OPERATIONS.

     We will be subject to the regulatory regimes in each of the countries in
which we conduct business. Local regulations range from permissive to
restrictive, depending upon the country. Changes to existing regulations of
foreign countries may decrease the opportunities that are available for us to
enter into those markets, or may increase our legal, administrative or
operational costs, or may constrain our activities in other ways that we cannot
necessarily anticipate. Any of these developments could impair our efforts to
develop foreign operations.

WE EXPECT TO INCUR OPERATIONAL AND MANAGEMENT INEFFICIENCIES WHEN WE ACQUIRE NEW
BUSINESSES.

     Part of our expansion strategy includes acquiring businesses and
technologies that we believe will complement our existing business. For example,
in 1999 we acquired two companies, and we may acquire additional companies in
the future. These acquisitions will likely involve some or all of the following
risks:

     - difficulty of assimilating acquired operations and personnel and
       information systems;

     - potential disruption of our ongoing business;

     - diversion of resources;

     - possible inability of management to maintain uniform standards, controls,
       procedures and policies;

     - possible difficulty of managing our growth;

     - risks of entering markets in which we have little experience; and

     - potential impairment of relationships with employees or clients.

     We may need to complete these transactions in order to remain competitive.
We cannot be sure that we will be able to obtain required financing for these
transactions or that these transactions will occur.

WE EXPECT TO REQUIRE ADDITIONAL THIRD-PARTY FINANCING, AND IF WE CANNOT OBTAIN
THIS FINANCING ON COMMERCIALLY REASONABLE TERMS, OUR ABILITY TO EXPAND OUR
BUSINESS WILL SUFFER.

     Our ability to meet our planned growth will require substantial cash
resources. We expect that the anticipated expansion of our UTX facilities,
including the completion of five UTX facilities currently under construction,
and the beginning of the construction of eight additional facilities during the
year 2000 (at an estimated average cost of $3.2 million per facility), and our
anticipated funding of negative cash flow from operating activities, will
require substantial capital. In addition, part of our expansion strategy
includes acquiring complementary businesses and technology, which may require us
to raise additional funds. We do not expect to generate significant cash flow
from operations in the near term. Accordingly, our ability to meet our
additional future capital needs will depend upon our ability to renegotiate,
extend or replace our credit facilities, obtain supplemental financing or raise
additional capital. Additional debt financing may limit our financial and
operating flexibility. We may not be able to renegotiate or replace our credit
and equipment lease facilities on a timely basis, on acceptable terms or at all.
Additional equity financing may not be available or may be dilutive to existing
stockholders. If we are unable to obtain future financing when needed or on
acceptable terms we may have to delay or abandon our development and expansion
plans, which could materially adversely affect our growth and ability to
compete.

                                       16

WE MUST EXPAND OUR MARKETING AND SALES OPERATIONS SUBSTANTIALLY TO INCREASE
MARKET AWARENESS AND SALES OF OUR SERVICES.

     Our services require a sophisticated sales effort that targets key people
within our prospective clients' organizations. This sales effort requires the
efforts of select personnel as well as specialized system and consulting
engineers within our organization. We have recently expanded our sales force and
plan to hire additional marketing and sales personnel and system and consulting
engineers, particularly individuals with experience in the telecommunications
industry. Competition for these individuals is intense, and we may not be able
to hire the number of qualified sales personnel and system and consulting
engineers we need. In addition, we may substantially increase our budget as part
of our marketing program. If we are unable to expand our marketing and sales
operations, we may not be able to increase market awareness or sales of our
products and services, which may prevent us from achieving and maintaining
profitability.

IF WE DO NOT EXPAND OUR CLIENT SUPPORT ORGANIZATION SUBSTANTIALLY, CLIENTS MAY
SIGNIFICANTLY REDUCE PURCHASES OF OUR SERVICES.

     We currently have a small client support organization and will need to
increase our staff to support new clients and the expanding needs of existing
clients. Our client support organization is responsible for providing our
clients with technical and operational support, and for identifying and
developing opportunities to provide additional services to our existing clients.
Competition for qualified client support personnel is intense because few people
have the necessary level of technical skills and experience in
telecommunications provisioning and network management. If we fail to expand our
client support organization, we may be limited in our ability to gain more
business from existing clients, and we may be unable to obtain or maintain
current information regarding our clients' and suppliers' communications
networks, which could limit our ability to provision future circuits for our
clients.

IF WE DO NOT ESTABLISH AND MAINTAIN KEY CLIENT RELATIONSHIPS, OUR REVENUES MAY
DECLINE.

     Our success will depend upon our ability to develop and manage key client
relationships in order to generate additional revenues from existing clients.
Our ability to develop and manage our client relationships depends on, among
other things:

     - our ability to maintain the timeliness and quality of our services in
       facilitating the supply of circuits;

     - our ability to deliver our clients additional services, such as network
       monitoring, maintenance and troubleshooting services;

     - our ability to expand our client support organization with additional,
       qualified personnel; and

     - performance by the transport suppliers with whom we contract to provide
       circuits to our clients.

     If we fail to establish and maintain these client relationships, our
revenues may stagnate or decline.

IF WE FAIL TO MANAGE EXPANSION EFFECTIVELY, OUR ABILITY TO INCREASE OUR SERVICES
AND CLIENT BASE COULD SUFFER.


     Our ability to successfully offer our services and implement our business
plan in a rapidly evolving market requires an effective planning and management
process. We continue to increase the scope of our operations and have
substantially increased the number of our employees. At December 31, 1997, we
had a total of five employees and at March 13, 2000, we had approximately 250
full-time employees. In addition, we plan to continue to hire a significant
number of employees. This growth has placed, and our anticipated growth in
future operations will continue to place, a significant strain on our management
systems and resources. We expect that we will need to continue to improve our
financial and managerial controls, reporting systems and procedures, and will
need to continue to


                                       17
<PAGE>   20

expand, train and manage our work force. Furthermore, we expect that we will be
required to manage multiple relationships with various clients, suppliers and
other third parties. We cannot be sure that we will be able to manage our
expansion effectively.

IF WE FAIL TO SUCCESSFULLY COMPLETE THE IMPLEMENTATION OF OUR MANAGEMENT
INFORMATION SYSTEMS OUR ABILITY TO EXPAND OUR BUSINESS COULD SUFFER.

     We are in the process of augmenting our management information systems to
facilitate management of client orders, client service, billing and financial
applications. Our ability to manage our business could be harmed if we fail to
successfully and promptly:

     - implement all applications of our management information systems;

     - integrate all the client records and the billing, ordering, inventory,
       management, accounting and other financial information systems of the
       businesses we have acquired or may acquire into our management
       information systems;

     - identify all of our information and processing needs;

     - repair "bugs" and design defects that may exist in our management
       information systems;

     - implement a wide area network connecting our main offices and our UTX
       facilities in different geographic locations; or

     - maintain and upgrade our management information systems as necessary.

     In addition, our ability to efficiently operate our business could suffer
if the software which runs our information systems malfunctions.

WE DEPEND ON OUR KEY PERSONNEL TO MANAGE OUR BUSINESS EFFECTIVELY IN A RAPIDLY
CHANGING MARKET, AND OUR ABILITY TO GENERATE REVENUES WILL SUFFER IF WE ARE
UNABLE TO RETAIN OUR KEY PERSONNEL AND HIRE ADDITIONAL PERSONNEL.

     Our future success depends upon the continued services of our executive
officers and other key sales, marketing and support personnel. In particular, we
rely upon the services of our President and Chief Executive Officer, Patrick C.
Shutt, and Chief Operating Officer, Robert J. Pommer, Jr. We do not have "key
person" life insurance policies covering any of our employees.

     In addition, we depend on the ability of a relatively new management team
to effectively execute our strategies. We recently hired several of our key
employees. Between June and February 2000, we hired our Executive Vice President
of Marketing and Executive Vice President of Client Services. Because some
members of our management team have worked together only for a short period of
time, we need to integrate these officers into our operations.

     We will need to hire additional personnel in our communications
provisioning, sales, marketing and support areas in the future, and we believe
our success depends, in large part, upon our ability to attract and retain these
key employees. Competition for these persons is intense, especially in the
communications provisioning area. In particular, we have experienced difficulty
in hiring qualified network engineers, and we may not be successful in
attracting and retaining these individuals. The loss of the services of any of
our key employees, the inability to attract or retain qualified personnel in the
future, or delays in hiring required personnel could limit our ability to
generate revenues.

BECAUSE WE HAVE NO PATENTED TECHNOLOGY AND HAVE LIMITED ABILITY TO PROTECT OUR
PROPRIETARY INFORMATION, COMPETITORS MAY MORE EASILY ENTER OUR MARKET AND HARM
OUR ABILITY TO GENERATE REVENUES.

     We have no patented technology that would preclude or inhibit competitors
from entering our market. We rely on a combination of copyright, trademark,
service mark and trade secret laws and contractual restrictions to establish and
protect our intellectual property. We have no federally
                                       18
<PAGE>   21

registered trademarks or service marks, although we have applied for
registration of certain of our service marks. Even if registration is granted,
we may be limited in the scope of services for which we may exclusively use our
service marks. We enter into confidentiality agreements with our employees,
consultants and partners, and we control access to, and distribution of, our
proprietary information. Our intellectual property may be misappropriated or a
third party may independently develop similar intellectual property. Moreover,
the laws of certain foreign countries may not protect our intellectual property
rights to the same extent as do the laws of the United States. Unauthorized use
of any of our proprietary information could expose us to competition which would
harm our ability to attract new and existing clients and generate revenues.

UNDETECTED COMPUTER ERRORS ASSOCIATED WITH THE YEAR 2000 PROBLEM COULD DISRUPT
OUR OPERATIONS.

     The year 2000 computer problem refers to the potential for system and
processing failures of date-related data as a result of computer-controlled
systems using two digits rather than four to define the applicable year. To
date, we have not encountered any problems relating to the well-publicized year
2000 computer problem. While we do not anticipate a material business
interruption, there remain risks that not all year 2000 problems have been
discovered. For example, the year 2000 is a leap year, which could cause
problems for computer hardware and software. If not fully resolved, the year
2000 computer problem could result in a system failure or miscalculations
causing disruptions of operations, including a temporary inability to process
transactions, send invoices or engage in similar normal business activities.

     We have designed our UIX databases for use in the year 2000 and beyond, and
we believe they are year 2000 compliant. Although we are past January 1, 2000,
and we believe that our UIX databases will function during the year 2000, we may
yet discover that our UIX databases may have problems because of the year 2000
calendar change. In addition, we may still find problems with our internal
systems. In either event, our ability to generate revenues could suffer. If our
suppliers, vendors, major distributors, partners, clients and service providers
fail to correct their year 2000 problems, these failures could disrupt our
operations, damage our relationships with our clients and harm our business. If
a year 2000 problem occurs, it may be difficult to determine which party's
products caused the problem. Due to the general uncertainty inherent in the year
2000 readiness of third-party suppliers and vendors, we are unable to determine
at this time whether year 2000 failures could harm our business and our
financial results.

     Our clients' purchasing plans could be affected by year 2000 issues if they
need to expend significant resources to fix their existing systems to become
year 2000 compliant. This situation may reduce funds available to employ our
services. In addition, some clients may wait to purchase our services until
after the year 2000, which may reduce our revenues in the short term. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Year 2000 Compliance".

THERE HAS BEEN NO PRIOR MARKET FOR OUR COMMON STOCK, AND A PUBLIC MARKET MAY NOT
DEVELOP OR BE SUSTAINED.

     Prior to this offering, you could not buy or sell our common stock
publicly. An active public market for our common stock may not develop or be
sustained after this offering, and the market price might fall below the initial
public offering price. The initial public offering price may bear no
relationship to the price at which our common stock will trade upon completion
of this offering. The initial public offering price will be determined based on
negotiations between us and the representatives of the underwriters, based on
factors that may not be indicative of future market performance. See
"Underwriting".

                                       19
<PAGE>   22

CERTAIN STOCKHOLDERS WILL CONTINUE TO HAVE SUBSTANTIAL CONTROL OVER UNIVERSAL
ACCESS AFTER THIS OFFERING AND COULD DELAY OR PREVENT A CHANGE IN CORPORATE
CONTROL.


     We anticipate that Internet Capital Group, Inc., funds affiliated with
ComVentures and other stockholders, directors and officers will, in the
aggregate, beneficially own approximately 55.84% of our outstanding common stock
following the completion of this offering assuming these entities and
individuals do not purchase additional shares in the offering. We have requested
the underwriters reserve up to 2,300,000 shares in this offering for purchase by
Internet Capital Group, Inc., although it has no obligation to buy any shares in
the offering. These stockholders, acting alone or together, would be able to
influence significantly all matters requiring approval by our stockholders,
including the election of directors and the approval of mergers or other
business combination transactions. See "Principal and Selling Stockholders".


PROVISIONS OF OUR CHARTER DOCUMENTS MAY HAVE ANTI-TAKEOVER EFFECTS THAT COULD
PREVENT A CHANGE IN CORPORATE CONTROL.

     Provisions of our amended and restated certificate of incorporation,
bylaws, and Delaware law could make it more difficult for a third party to
acquire us, even if doing so would be a benefit to our stockholders. See
"Description of Capital Stock".

THERE MAY BE SALES OF A SUBSTANTIAL AMOUNT OF OUR COMMON STOCK AFTER THIS
OFFERING THAT COULD CAUSE OUR STOCK PRICE TO FALL.


     Our current stockholders hold a substantial number of shares of our common
stock, which they will be able to sell in the public market in the near future.
All of the 11,000,000 shares sold in this offering will be freely tradable. The
remaining 76,460,616 shares outstanding, based on the number of shares
outstanding as of March 10, 2000, are restricted securities as defined in Rule
144 of the Securities Act of 1933. Approximately 5,050,766 shares will be
tradable, subject to certain conditions described in "Shares Eligible for Future
Sale", three business days after we publicly announce financial results for the
full fiscal quarter next following the fiscal quarter in which the date of this
prospectus falls. Approximately 61,382,506 of these shares will be tradable
beginning 180 days after the effective date of this offering, and the remainder
will become freely tradable at various times thereafter subject to certain
conditions described in "Shares Eligible for Future Sale". Sales of a
substantial number of shares of our common stock after this offering, or market
expectations that these sales may occur, could cause our stock price to fall. In
addition, the sale of these shares could impair our ability to raise capital by
selling additional common stock. See "Shares Eligible for Future Sale".


WE EXPECT TO EXPERIENCE VOLATILITY IN OUR SHARE PRICE WHICH COULD NEGATIVELY
AFFECT YOUR INVESTMENT.

     The market price of our common stock may fluctuate significantly in
response to a number of factors, some of which are beyond our control,
including:

     - quarterly variations in operating results;

     - changes in financial estimates by securities analysts;

     - changes in market valuations of Internet-related companies;

     - announcements by us or our competitors of new products and services or of
       significant acquisitions, strategic partnerships or joint ventures;

     - any loss of a major customer;

     - additions or departures of key personnel;

     - any deviations in net revenues or in losses from levels expected by
       securities analysts;

                                       20
<PAGE>   23

     - future sales of common stock; and

     - volume fluctuations, which are particularly common among highly volatile
       securities of Internet-related companies.

YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION.

     The initial public offering price is substantially higher than the book
value per share of our outstanding common stock immediately after the offering.
Accordingly, if you purchase common stock in the offering, you will incur
immediate dilution of approximately $7.37 per share. You will incur further
dilution if outstanding stock options and warrants are exercised. See
"Dilution".

                   NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Some of the information in this prospectus contains forward-looking
statements that involve substantial risks and uncertainties. You can identify
these statements by forward-looking words such as "may", "will", "expect",
"anticipate", "believe", "estimate", "plan" and "continue" or similar words. You
should read statements that contain these words carefully because they: (1)
discuss our future expectations; (2) contain projections of our future results
of operations or of our financial condition; or (3) state other
"forward-looking" information. We believe that it is important to communicate
our future expectations to our investors. However, there may be events in the
future that we have not accurately predicted or which we cannot control. These
events may include our future operating results, our ability to implement our
business plan, our efforts to address Year 2000 issues and potential
competition, among other things. The risk factors listed under "Risk Factors",
as well as any cautionary language in this prospectus, provide examples of
risks, uncertainties and events that may cause our actual results to differ
materially from the expectations we describe in our forward-looking statements.

                                USE OF PROCEEDS


     We estimate that the net proceeds to us from the sale of the 11,000,000
shares of common stock we are selling in the offering will be approximately
$90.6 million (or $104.4 million if the underwriters' option to purchase
additional shares as described in "Underwriting" is exercised in full), based on
an assumed initial public offering price of $9.00 per share and after deducting
an assumed underwriting discount and estimated offering expenses payable by us.


     We expect to use the net proceeds from this offering for working capital,
capital expenditures and general corporate purposes. In addition, we may use a
portion of the net proceeds to acquire complementary products, technologies or
businesses; however, we currently have no commitments or agreements, nor are we
involved in any negotiations, with respect to any such transactions. Pending use
of the net proceeds of this offering, we intend to invest the net proceeds in
interest-bearing, investment-grade securities.

                                DIVIDEND POLICY

     We have never declared or paid any dividends on our capital stock. We
currently expect to retain future earnings, if any, to operate and expand our
business and do not expect to pay any cash dividends in the foreseeable future.

                                 CAPITALIZATION

     The following table sets forth our capitalization as of December 31, 1999:

     - on an actual basis;

     - on a pro forma basis giving effect to the conversion of all outstanding
       shares of preferred stock into common stock and all preferred stock
       warrants to common stock warrants upon the closing of the offering
       (assuming that each share of Series E preferred stock converts into three
       shares of common stock); and

     - on a pro forma as adjusted basis to reflect the sale by us of 11,000,000
       shares of common stock in the offering at an assumed initial public
       offering price of $9.00 per share, after deducting an assumed
       underwriting discount and estimated offering expenses.

     This information should be read in conjunction with our financial
statements and the notes to those statements appearing elsewhere in this
prospectus.

                                    DILUTION

     If you invest in our common stock, your interest will be diluted to the
extent of the difference between the initial public offering price per share of
our common stock and the pro forma as adjusted net tangible book value per share
of our common stock after this offering. We calculate net tangible book value
per share by dividing the net tangible book value (total assets less intangible
assets and total liabilities) by the number of outstanding shares of common
stock.

     Our pro forma net tangible book value at December 31, 1999 was $49.6
million, or $0.66 per share, based on 74,809,264 shares of our common stock
outstanding after giving effect to the conversion of all outstanding shares of
preferred stock into common stock.

     After giving effect to the sale of the 11,000,000 shares of common stock by
us at an assumed initial public offering price of $9.00 per share (less an
assumed underwriting discount and estimated offering expenses payable by us),
our pro forma net tangible book value at December 31, 1999 would be $140.2
million, or $1.63 per share. This represents an immediate increase in the pro
forma net tangible book value of $0.97 per share to existing stockholders and an
immediate dilution of $7.37 per share to new investors, or approximately 82% of
the assumed initial public offering price of           per share.

     The following table illustrates this per share dilution:

     The following table shows on a pro forma basis at December 31, 1999, after
giving effect to the conversion of all outstanding shares of our preferred stock
into an aggregate of 42,834,243 shares of common stock upon the closing of this
offering, the number of shares of common stock purchased from us, the total
consideration paid to us and the average price paid per share by existing
stockholders and by new investors purchasing common stock in this offering:

                            SELECTED FINANCIAL DATA

     The selected financial data set forth below should be read in conjunction
with our financial statements and the notes to our financial statements and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations", included elsewhere in this prospectus. The statement of operations
data for the period from inception through December 31, 1997, and the years
ended December 31, 1998 and 1999, and the balance sheet data as of December 31,
1997, 1998 and 1999 are derived from, and are qualified by reference to, the
audited financial statements included elsewhere in this prospectus.

     The financial data as of and for the year ended December 31, 1999 reflects
the acquisitions of substantially all of the assets of Pacific Crest Networks,
Inc. and Stuff Software, Inc. on July 30, 1999 and November 1, 1999,
respectively. Both acquisitions were accounted for using the purchase method of
accounting.

     Pro forma basic and diluted net loss per share have been calculated
assuming the conversion into common stock of all preferred stock outstanding
during the relevant period, as if the shares had converted immediately upon
their issuance.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion of our financial condition and results of
operations should be read in conjunction with "Selected Financial Data" and our
financial statements and the notes to our financial statements included
elsewhere in this prospectus. This discussion contains forward-looking
statements that involve risks and uncertainties. Our actual results could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors including the risks described in "Risk Factors" and
elsewhere in this prospectus.

OVERVIEW

     We commenced operations on October 2, 1997. To date, we have derived
substantially all of our revenues from providing ongoing, dedicated circuit
access. Monthly recurring circuit revenues are generated under client contracts
with terms ranging from 12 to 60 months. Contracts with our clients may be
terminated by the client at any time. However, a client that cancels a contract
is required to pay us substantially all of the amounts payable over the
remaining term of the contract. Circuit charges are billed monthly in advance,
and circuit revenues are recognized in the month that service is provided.
Amounts billed in advance are recorded on the balance sheet as unearned revenue.
At December 31, 1999, unearned revenue was $2.1 million.

     Monthly recurring UTX revenues are generated from leasing space in our UTX
facilities. To date we have derived minimal revenue from UTX activities. Our UTX
billing and revenue recognition policies are the same as those described above
for circuits. In addition, we facilitate the provisioning, installation and
servicing of point-to-point dedicated circuits for our clients. To date, we have
not charged our clients for provisioning, installation or network management
services.

     At March 7, 2000, we had two operational UTX facilities and five UTX
facilities under construction. Construction, equipment and facility leasing
costs incurred in connection with the construction of a UTX facility are
capitalized until the facility becomes operational. Once the facility becomes
operational, these costs are amortized over the lesser of the term of the lease,
ranging from seven to 15 years, or the estimated useful life of the equipment.
At December 31, 1999, we had $16.2 million of capitalized UTX construction
costs. In addition, at December 31, 1999, we had outstanding commitments of
approximately $9.5 million with respect to UTX construction services and
approximately $28.5 million with respect to facility leases. In addition to the
two operational UTX facilities and five facilities under construction at March
7, 2000, we expect to commence construction on eight additional facilities
during 2000.

     Our clients are communications service providers and transport suppliers,
such as Internet service providers, competitive local exchange carriers,
incumbent telecommunication service providers and other application and network
service providers. Our largest two clients represented an aggregate of
approximately 29% of total revenues for the year ended December 31, 1998. Our
largest client represented approximately 38% of total revenues for the year
ended December 31, 1999.

     To date, cost of circuit access consists of amounts paid to transport
suppliers for circuits. We have negotiated volume discounts and network
route-specific discounts under contracts with the majority of our suppliers.
These contracts generally have terms ranging from three to ten years and include
minimum monthly purchase commitments that begin anywhere from six to twelve
months after we enter into the contract. At December 31, 1999, these minimum
purchase commitments totaled approximately $500,000 per month. However, actual
purchases have exceeded these minimum purchase commitments and for the year
ended December 31, 1999, totaled approximately $12.0 million. In addition, we
are party to contracts that will impose additional minimum purchase commitments
that we anticipate will total approximately $1.8 million per month by September
2000. In future periods we will incur costs associated with the UTX facilities
which will include amortization of certain UTX equipment costs and certain
technical labor.

                                       26
<PAGE>   29

     Operations and administration costs consist primarily of salaries and
employee benefits, facilities expenses for our headquarters and sales offices,
and sales and marketing expenses. We did not open our first sales offices until
June 1999 at which time we began to significantly expand our sales and marketing
staff. As a result, we have not historically segregated sales and marketing
expenses from operations and administration expenses.

     In July 1999, we acquired substantially all of the assets of Pacific Crest
Networks, Inc. in a transaction accounted for as a purchase. Intangible assets
of approximately $1.2 million were recorded in connection with the acquisition
and are amortized over five years. In addition, in November 1999, we acquired
substantially all of the assets of Stuff Software, Inc. in a transaction
accounted for as a purchase. Intangible assets of $1.3 million were recorded in
connection with the acquisition and are being amortized over five years.

     In each quarter since our inception, we have incurred operating losses and
net losses and experienced negative cash flows from operations. At December 31,
1999, we had an accumulated deficit of $23.0 million.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1999

REVENUES

     Revenues increased from $1.6 million for the year ended December 31, 1998
to $14.3 million for the year ended December 31, 1999. Substantially all of our
revenues consisted of circuit revenues in each of these periods. UTX revenues
represented less than 5% of revenues during these periods. The increase in
revenues was attributable to an increase in the volume of circuits sold, some of
which were higher capacity and, therefore, generated greater revenues per
circuit. In addition, there was an increase in the number of clients and
additional sales to existing clients.

COST OF CIRCUIT ACCESS

     Cost of circuit access increased from $1.3 million for the year ended
December 31, 1998 to $12.0 million for the year ended December 31, 1999. As a
percentage of revenues, cost of circuit access increased from 77% for the year
ended December 31, 1998 to 84% for the year ended December 31, 1999. The
increase in cost of circuit access in absolute dollars was primarily
attributable to an increase in the volume of circuits sold, some of which were
higher capacity and, therefore, generated greater cost per circuit. In addition,
there was an increase in the number of clients and additional sales to existing
clients. The increase in cost of circuit access as a percentage of revenues was
in part attributable to the fact that we deliberately reduced our margins on
certain high capacity circuits in an effort to attract large clients, and in
part attributable to $350,000 of circuit charges incurred for circuits that are
yet to be sold to clients.

     In April 1999 we reduced the margins on certain circuits sold to two high
profile clients in an effort to attract these clients. These margin reductions
were one-time occurrences. We do not expect to decrease margins on future sales.

OPERATIONS AND ADMINISTRATION (EXCLUDING STOCK OPTION PLAN COMPENSATION)

     Operations and administration expenses increased from $1.5 million for the
year ended December 31, 1998 to $13.6 million for the year ended December 31,
1999. The increase in operations and administration expenses was primarily
attributable to an increase in personnel and continued expansion of our sales
and marketing efforts. During the year ended December 31, 1999, we opened sales
offices in Vienna, Virginia and San Jose, California. The number of our
employees increased from 11 at December 31, 1998 to 135 at December 31, 1999. In
addition, we incurred bad debt expense of $42,000 for the year ended December
31, 1998 and $867,000 for the year ended December 31, 1999. Approximately
one-half of the increase in bad debt expense related to one

                                       27
<PAGE>   30


substantial client account, which represented over four months of billings. We
have revised our credit and collection procedures so that service is now
discontinued within two months of non-payment. The remainder of the increase in
bad debt expense is related to the creation of a general reserve for doubtful
accounts. Finally, we sold Series D Preferred Stock to service providers during
1999 for $992,000 less than the deemed fair market value of the stock at the
date of sale. Accordingly, we recognized this amount as operations and
administration expense during 1999. We expect total operations and
administration expenses to continue to increase in absolute dollars as we
continue to grow our revenues, but expect that operations and administration
expenses will ultimately decrease as a percentage of revenues as we leverage our
existing infrastructure.


OPERATIONS AND ADMINISTRATION (STOCK OPTION PLAN COMPENSATION)

     During 1998, we recorded a total of $2.0 million and during the year ended
December 31, 1999, we recorded a total of $14.1 million in deferred stock option
plan compensation as a result of granting options to employees and non-employees
with per share exercise prices deemed to be below the fair market value of our
common stock at the date of grant. Deferred stock option plan compensation is
amortized over the vesting period of the related options. Amortization expense
totaled $3.5 million for the year ended December 31, 1999. We expect to
recognize additional deferred stock option plan compensation expense of
approximately $11.9 million over the next four years, based upon options
outstanding at December 31, 1999.

     In addition, during the year ended December 31, 1999 we recorded $4.6
million of stock option plan compensation expense, related to loans issued to
three officers of the Company, in connection with exercise of stock options.

DEPRECIATION

     Depreciation expense includes depreciation of furniture, fixtures and
equipment at our office facilities and of equipment at our UTX facilities. We
expect depreciation expense to increase substantially in the future as we
continue to place our UTX facilities into service.

INTEREST EXPENSE AND INTEREST INCOME

     Interest expense increased from $27,000 for the year ended December 31,
1998 to $81,000 for the year ended December 31, 1999. The increase was
attributable to additional borrowings under a term loan and line of credit
facility used for general working capital requirements and to fund capital
expenditures.

     Interest income increased from $8,000 for the year ended December 31, 1998
to $739,000 for the year ended December 31, 1999. The increase was attributable
to investing a portion of the proceeds from our Series A, Series B, Series C,
Series D and Series E preferred stock offerings in short-term money market
instruments.

INCOME TAXES

     From our inception through September 27, 1998, we elected to be treated as
a subchapter S-corporation for income tax purposes. On September 27, 1998, we
converted to a C-corporation. At December 31, 1999, we had approximately
$10,091,000 of federal and state net operating loss carryforwards. These
carryforwards may be available to offset future taxable income. Our federal and
state net operating loss carryforwards expire at various dates beginning in
2018. Due to the uncertainty that we will generate future earnings sufficient to
enable us to realize the benefit of these net operating loss carryforwards, we
have recorded a valuation allowance for the full amount of our deferred tax
asset. As a result, no income tax benefit has been recorded in our statement of
operations. We assess the realizability of our deferred tax asset on an ongoing
basis and adjust the valuation allowance based on this assessment. Additionally,
Section 382 of the Internal Revenue Code of 1986, as amended imposes annual
limitations on the use of net operating loss carryforwards if

                                       28
<PAGE>   31

there is a change in ownership, as defined, within any three year period. The
utilization of certain net operating loss carryforwards may be limited due to
our capital stock transactions.

PERIOD FROM INCEPTION TO DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31,
1998

REVENUES

     We commenced operations on October 2, 1997. Revenues increased from $77,000
during the period ended December 31, 1997 to $1.6 million during the year ended
December 31, 1998. The increase in revenues was primarily attributable to growth
in the number of our clients.

COST OF CIRCUIT ACCESS

     Cost of circuit access increased from $66,000 for the period ended December
31,1997 to $1.3 million for the year ended December 31, 1998. As a percentage of
total revenues, cost of circuit access decreased from 86% for the period ended
December 31, 1997 to 77% for the year ended December 31, 1998. The increase in
cost of circuit access in absolute dollars was attributable to an increase in
the number of circuits purchased. The decrease in cost of circuit access as a
percentage of revenues was attributable to volume discounts negotiated with our
transport suppliers, reflecting higher purchasing levels.

OPERATIONS AND ADMINISTRATION (EXCLUDING STOCK OPTION PLAN COMPENSATION)

     Operations and administration expenses increased from $180,000 for the
period ended December 31, 1997 to $1.5 million for the year ended December 31,
1998. The increase was primarily attributable to growth in headcount and
expansion of our corporate headquarters. Our employee headcount increased from
five at December 31, 1997 to 20 at December 31, 1998.

OPERATIONS AND ADMINISTRATION (STOCK OPTION PLAN COMPENSATION)

     During 1998, we recorded a total of $2.0 million in deferred stock option
plan compensation as a result of granting options to employees with per share
exercise prices determined to be below the fair market value of our common stock
at the date of grant. Amortization expense totaled $389,000 for the year ended
December 31, 1998. In addition, during 1998, we recorded $300,000 of stock
option plan compensation in connection with options issued to non-employees in
exchange for services.

INTEREST EXPENSE AND INTEREST INCOME

     Interest expense increased from $1,000 for the period ended December 31,
1997 to $27,000 for the year ended December 31, 1998. The increase was
attributable to additional borrowings from stockholders and under a term loan
used to fund our working capital needs.

OTHER EXPENSE

     Other expense totaled $100,000 for the year ended December 31, 1998. The
amount related to a settlement paid upon termination of an executed letter of
intent to acquire a network access service provider.

</TABLE>

     Our future revenues and operating results may vary significantly from
quarter to quarter due to a number of factors, many of which we cannot control.
These factors include those described in "Risk Factors" included elsewhere in
this prospectus.

LIQUIDITY AND CAPITAL RESOURCES

     We have financed our operations primarily through private placements as
well as through borrowings from stockholders and financial institutions. Since
inception through December 31, 1999, we have raised $63.4 million in capital
through private placements of common and convertible preferred stock and common
and preferred stock warrants. Our principal uses of cash are to fund operating
losses, working capital requirements and capital expenditures. At December 31,
1999, we had $38.0 million in cash and cash equivalents.

     In March 1999, we entered into a credit agreement with a bank under which
we may request the bank to issue letters of credit or we may borrow up to a
total of $4.0 million. The agreement provides that outstanding borrowings bear
interest at the bank's prime rate and expires in April 2000. This credit
agreement requires as to maintain a cash balance in a custodial account at an
amount not less than the total borrowings and letters of credit outstanding.
Letters of credit totaling $1.7 million were outstanding under the agreement as
of December 31, 1999. At January 31, 2000, letters of credit totaling $500,000
were outstanding under the agreement.

     In September 1999, we entered into a credit agreement with a bank under
which we may request the bank to issue letters of credit or we may borrow up to
a total of $6.0 million. The agreement expires in August 2000. Outstanding
borrowings under the agreement bear interest at rates ranging from the bank's
prime rate to the bank's prime rate plus 3% and are secured by substantially all
of our assets. The agreement requires that we maintain specified debt to
tangible net worth and quick ratios. The Company was in compliance with both
ratios at December 31, 1999. Letters of credit totaling $2.2 million were
outstanding under the agreement as of December 31, 1999.

     In December 1999, we entered into a credit agreement with a bank and
borrowed $3.3 million. Outstanding borrowings bear interest at approximately 15%
and are secured by specifically identified assets. The agreement expires in
November 2002 and requires that we maintain an unrestricted cash balance of at
least $15 million. As of December 31, 1999, the outstanding balance of this loan
was $3.2 million.

     Net cash used in operating activities increased from $946,000 for the year
ended December 31, 1998 to $6.9 million for the year ended December 31, 1999.
The increase in net cash used was

                                       30
<PAGE>   33

primarily due to increased net losses and increased accounts receivable,
partially offset by increased accounts payable, accrued expenses and unearned
revenue. We anticipate that we will continue to require cash to support our
future operating activities.

     Net cash used in investing activities totaled $265,000 for the year ended
December 31, 1998 and related to purchases of property and equipment. Net cash
used in investing activities totaled $19.6 million for the year ended December
31, 1999, and related to purchases of property and equipment, funds advanced in
exchange for notes receivable, and the purchases of Pacific Crest Networks and
Stuff Software, Inc. We expect to increase our investments in equipment in the
near term substantially as we increase our number of UTX facilities.

     At December 31, 1999 we had two operational UTX facilities and five
facilities under construction. In addition to these facilities we intend to
commence construction on eight additional facilities during 2000.

     We plan to spend approximately $50.0 million on capital expenditures during
2000, including approximately $6.0 million on the completion of the five
facilities under construction and $25.6 million on the construction of eight
additional facilities, the remainder of which will be used to fund the expansion
of corporate facilities and the build out of corporate infrastructure. We
anticipate we will use part of the proceeds of this offering for these capital
expenditures.

     Net cash provided by financing activities increased from $2.1 million for
the year ended December 31, 1998 to $63.7 million for the year ended December
31, 1999. The increase was primarily due to the receipt of proceeds from the
issuance of convertible preferred stock. Pending their use, we invested these
proceeds primarily in marketable securities, with an original maturity of not
greater than six months. We intend to continue investing surplus cash in similar
securities.

     In July 1999, we acquired substantially all of the assets and assumed
certain liabilities of Pacific Crest Networks, Inc. for a total purchase price
of $1.4 million (comprised of $1.1 million in a cash and the assumption of debt,
and 82,353 shares of Series D convertible preferred stock with a fair market
value of $4.25 per share on the date of issuance). In November 1999, we acquired
substantially all of the assets of Stuff Software, Inc. for a total purchase
price of $1.2 million (comprised of $930,000 in cash and 50,021 shares of common
stock with a fair market value of $6.10 per share on the date of issuance). The
cash portion of these purchases was funded with proceeds from the issuance of
convertible preferred stock.

     Our future capital requirements will depend on a number of factors,
including market acceptance of our services, the resources we devote to
developing, selling and marketing our services and the rate at which we expand
our UTX facilities. In addition, we plan to continue to evaluate possible
investments in complementary businesses, products and technologies. Although we
believe that the net proceeds from this offering, together with existing cash
balances, will be sufficient to fund our operations for at least the next twelve
months, we may require additional financing within this time frame. Additional
funding may not be available on terms acceptable to us, or at all.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE SENSITIVITY

     We maintain our cash equivalents and short-term investments primarily in a
portfolio comprised of commercial paper, money market funds and investment grade
debt securities. As of December 31, 1999, all of our investments had maturities
of less than six months. Accordingly, we do not believe that our investments
have significant exposure to interest rate risk.

EXCHANGE RATE SENSITIVITY

     We operate primarily in the United States, and all our revenues and
expenses to date have been in US dollars. Accordingly, we have had no material
exposure to foreign currency rate fluctuations.

<PAGE>   34

YEAR 2000

IMPACT OF THE YEAR 2000 COMPUTER PROBLEM

     The year 2000 computer problem refers to the potential for system and
processing failures of date-related data as a result of computer-controlled
systems using two digits rather than four to define the applicable year. For
example, computer programs that have time-sensitive software may recognize a
date represented as "00" as the year 1900 rather than the year 2000. This could
result in a system failure or miscalculations causing disruptions of operations,
including among other things, a temporary inability to process transactions,
send invoices, or engage in similar normal business activities.

STATE OF READINESS

     We completed our assessment of our year 2000 readiness and our inventory
and testing of certain internal systems. We are currently requesting
confirmation of year 2000 compliance from our suppliers.

     Based upon our year 2000 assessment, we do not believe that we have any
significant systems that are not year 2000 compliant. We have represented to
some of our customers that our computer systems will continue to process date
data in the year 2000 and beyond, including leap year calculations.

     The applications for our UIX databases were developed internally within the
last two years using year 2000 compliant equipment, operating systems and
software development tools. We developed these databases and systems to be year
2000 compliant. We have obtained assurances from third parties or internally
verified that the systems and equipment in our UTX facilities are year 2000
compliant.

     We have used commercially available software to verify that our internally
used hardware and software, including applications used for accounting, order
entry and invoicing are year 2000 compliant.

     To date, we have not experienced any significant year 2000 problems.
However, a programming error that has not yet been discovered, whether in
hardware and software not used every day or otherwise, could still cause
problems during the year 2000 and harm our business.

COST

     Based on our assessments to date we believe that we will be able to manage
our year 2000 transition without any material adverse effect on our business or
results of operations. To date our costs of assessing our year 2000 readiness
have not been material.

RISKS

     We believe that our most significant year 2000 risk is that third parties,
such as transport suppliers and utility providers, do not fully address their
year 2000 issues.

     Failure of our transport suppliers to adequately address their year 2000
issues could result in circuit outages. We generally provide outage credits to
our clients if circuit disruptions occur. A high circuit failure rate may result
in lost revenues and lost customers and may divert resources from the expansion
of our services and adversely affect our business and results of operations. To
date, no circuit disruptions or failures have occurred as a result of the year
2000.

     Failure of our internal systems to be ready for year 2000 could delay order
processing, provisioning of circuits and issuing invoices. To date, we have
experienced no delays as a result of the year 2000.

                                       32
<PAGE>   35

CONTINGENCY PLAN

     We will continue to assess our year 2000 issues. We have developed a
contingency plan in the event our efforts to identify year 2000 problems are not
effective. This plan includes:

     - temporary relocation of head office functions;

     - using contract personnel to correct any problems;

     - using alternative sources of transport capacity; and

     - increasing work hours for our personnel.

     Based upon our evaluation of these issues, we believe that year 2000 issues
will not have a material impact on our financial condition or results of
operation. However, we cannot assure you that we will not be affected by such
issues. In addition, if any significant transport supplier, utility provider or
other third party with whom we deal fails to ensure year 2000 compliance, our
financial condition or results of operations could suffer.

                                    BUSINESS

OVERVIEW

     We are a business-to-business intermediary that facilitates the buying and
selling of capacity on communications networks. We facilitate the process
through which users of communications circuits obtain circuits dedicated for
their specific use from multiple vendors. We refer to this process as
"provisioning a circuit." We also facilitate the installation and servicing of
these dedicated circuits. Our clients are communications service providers, such
as telecommunications service providers, internet service providers and
application service providers, who buy capacity on communications circuits for
use by their customers. We obtain the communications capacity from transport
suppliers, who are the owners of the communications infrastructure over which
information is transmitted.

     Through our services, we provide our clients with an outsourced, integrated
solution to obtaining communications network capacity within a fragmented
network services market. The services we provide include:

     - assembling detailed information about available network capacity from
       multiple suppliers;

     - operating facilities where communications networks can be physically
       interconnected;

     - providing ongoing access to dedicated circuits; and

     - providing client support services.

We offer our clients the ability to obtain pricing quotes and circuit
availability information and to order circuits over the Internet. We intend to
expand our Internet service offering to include network management, monitoring
and restoration. Through these services, we provide our clients with an
outsourced, integrated solution to the challenges they face within a fragmented
network services market.

     As an independent intermediary, we have been able to collect and assemble
network information from multiple transport suppliers. Our UIX consists of
several proprietary, interconnected databases containing pricing, capacity,
availability, location and interconnection information, currently from over 35
transport suppliers and more than 75,000 physical sites. Our UIX enables us to
efficiently and cost-effectively facilitate the design, provisioning,
installation and maintenance of circuits across multiple vendor networks for our
clients. Our UTX facilities are physical sites where transport capacity
suppliers and our clients lease space to locate communications equipment and
interconnect with the networks of transport suppliers. Our UTX facilities enable
our clients to more easily extend the geographic reach of their networks through
interconnection. We also provide a single point of contact for network
management services, including network monitoring, maintenance and restoration.

     By assembling network information, managing physical network
interconnections and providing dedicated support services, we intend to improve
the overall efficiency of the network infrastructure services market and,
ultimately, create the foundation for a seamlessly connected, global
communications network.


     We were incorporated in Illinois and began operations in October 1997. We
reincorporated in Delaware in June 1999. We operated as a subchapter "S"
corporation until September 1998, when we converted to a "C" corporation. To
date, we have derived substantially all of our revenues from providing ongoing,
dedicated circuit access, generating our first revenues from this source in the
quarter ended December 31, 1997. At March 10, 2000 we had two operational UTX
facilities and five UTX facilities under construction. However, to date we have
derived minimal revenues from UTX facilities. In each quarter since our
inception, we have incurred operating losses and net losses and experienced
negative cash flows from operations. At December 31, 1999, we had an accumulated
deficit of $23.0 million.

INDUSTRY BACKGROUND

MARKET OPPORTUNITY

     The Internet is emerging as a global medium for communications and
commerce. According to International Data Corporation (IDC), the number of
Internet users will grow from 142 million at the end of 1998 to 502 million by
2003. Businesses in particular are becoming increasingly dependent on Internet
enabled applications to facilitate transactions and are using the Internet for a
variety of activities, including disseminating corporate information,
advertising, sales, customer service, training and communications with business
partners. Forrester Research estimates that U.S. business trade on the Internet
will grow from $43 billion in 1998 to $1.3 trillion in 2003.

     The growth in Internet usage, and in particular the adoption and use of the
Internet by businesses, has created substantial global demand for additional
network infrastructure and underlying communications capacity. We believe that
the increased reliance by businesses on data-intensive applications, including
data communications, electronic commerce, video and graphics, will continue to
support this trend. In addition, we believe that the resulting demand for
network capacity to transmit data will accelerate as communications service
providers increasingly offer high speed data access to businesses.

     According to the Yankee Group, the U.S. market for Internet capacity and
network services will total $56.8 billion by 2002. Service providers currently
rely on multiple suppliers of communications infrastructure. These suppliers
focus on any one or a combination of geographically dispersed network segments,
including local segments, intercity segments, interbuilding segments, and
segments connecting the networks of multiple providers. The ability of a service
provider to obtain dedicated circuits and infrastructure services quickly and
efficiently is becoming increasingly difficult as the number of transport
suppliers increases.

FRAGMENTED MARKET

     The market for communications network capacity and infrastructure services
is complex, competitive and fragmented due to the growth in the number of
service providers and suppliers of communications infrastructure. This growth is
attributed to the deregulation of the telecommunications industry beginning with
the 1984 divestiture of AT&T and continuing with the Telecommunications Act of
1996. The Telecommunications Act of 1996 has spawned a rapid increase in the
number of transport suppliers and service providers, including:

     - competitive local exchange carriers, which are communications companies
       authorized by local regulatory authorities to offer competing local
       communication services;

     - interexchange carriers, which are communications companies that offer
       service between local service areas in different geographic areas;

     - Internet service providers;

     - application service providers, which are companies that offer individuals
       or enterprises access over the Internet to application programs and
       related services that would otherwise have to be located in their own
       personal or enterprise computers;

     - cable operators; and

     - public utility companies.

     Similar deregulation is occurring in international markets. The increase in
the number of transport suppliers and service providers competing in and across
different geographically dispersed network segments has impeded the development
of seamless communications networks.

     With the growth in Internet communications and commerce and the
increasingly competitive market for network capacity and infrastructure
services, transport suppliers have employed a variety of

                                       35
<PAGE>   38

business strategies to compete. These strategies include building or acquiring
additional network infrastructure, entering into interconnection agreements,
reselling or exchanging network capacity and offering new services. As a result,
multiple networks have developed serving various geographic regions and focusing
on different network segments. In this competitive, multiple vendor market, we
believe that to date, transport suppliers have not been able to effectively
support dedicated circuit connections on their own networks, or through
efficient interconnection with other suppliers, to fully meet their customers'
requirements.

     Compounding the problems associated with a fragmented, multiple-vendor
market, transport suppliers and service providers have placed a higher priority
on obtaining customers to build market share rather than on interconnecting
their independently built networks. In addition, it is difficult to connect
networks together due to the fact that transport suppliers and service providers
do not have access to pricing, capacity, availability, and location information
for the networks of other suppliers. Because transport suppliers compete with
each other, they have little incentive to share this information or to locate
their equipment within competitors' facilities in order to connect their
networks.

CHALLENGES FOR SERVICE PROVIDERS

     The fragmented nature of the market causes a number of challenges for
telecommunications service providers, ISPs, ASPs and other buyers of
communication capacity, including:

     - significant time and expense related to obtaining and installing circuits
       across multiple vendor networks;

     - lack of information about vendor networks, making it difficult to
       determine the availability of capacity in a timely manner, which may
       result in significant backlog of customer orders, lost revenues and
       possibly lost customers; and

     - inability to maintain, monitor and restore connections across multiple
       vendor networks.

CHALLENGES FOR TRANSPORT SUPPLIERS

     The fragmented nature of the market also causes a number of challenges for
interexchange carriers, local loop, and other suppliers of communications
infrastructure, including:

     - inability to efficiently fulfill customer demand for dedicated circuits
       due to the limited coverage of their networks and limited
       interconnections with other carrier networks;

     - costs associated with selling excess network capacity on existing routes
       to multiple buyers; and

     - inability to provide a consistent level of service due to the lack of
       information about and control over network segments owned by multiple
       vendors.

OUR SOLUTION

     Our integrated solution addresses these challenges and provides the
following key advantages:

     SINGLE POINT OF CONTACT FOR SUPPLYING AND INSTALLING CIRCUITS AND PROVIDING
NETWORK MANAGEMENT SERVICES. As a third-party provider, we allow our clients to
outsource the obtaining, installing and providing of their communications
infrastructure. Our solution provides significant time, effort and cost savings
to our clients who would otherwise be forced to independently analyze the
capacity, availability and pricing of circuits from multiple vendors to
construct and maintain circuits. In addition, we maintain a network management
service organization through which we provide a single point of contact for
24-hour-a-day, seven-day-a-week network monitoring, maintenance and restoration
across multiple vendor networks. Our organization interfaces with the network
management organizations of our transport suppliers, which enables us to
identify and isolate circuit outages and facilitate their restoration throughout
each segment of dedicated circuits. Without these services a

                                       36
<PAGE>   39

client would have to contact multiple vendors to determine the source of a
circuit outage and to restore the circuit. We are currently providing these
services in conjunction with an outsourcing arrangement with a third party until
our own facility becomes operational.

     EFFICIENT, COST EFFECTIVE PROVISION AND INSTALLATION OF CIRCUITS ACROSS
MULTIPLE VENDOR NETWORKS. We efficiently and cost-effectively supply and install
circuits across multiple vendor networks to buyers of communications transport
capacity. As an independent intermediary, we have been able to collect network
information from multiple transport suppliers. Using this information, which is
contained in our UIX databases, we efficiently and cost effectively provide our
clients circuit solutions across geographically dispersed network segments.

     EASILY EXTENDED NETWORK COVERAGE. Suppliers of communications
infrastructure are able to easily extend the coverage of their networks by
purchasing access to dedicated circuits from us. We provide clients a single
point of contact from which to access the networks of over 35 transport
suppliers. In addition, by locating in our UTX facilities, we believe that
transport suppliers can access these networks faster and more cost-effectively,
utilizing a cross connect circuit connection within our UTX facility rather than
a local loop connection. With access to a greater number of circuit routes, our
clients are better positioned to offer a broader range of options to their
customers. We currently have two operational UTX facilities in two cities in the
United States and are in the process of constructing five additional sites.

     SIGNIFICANT SOURCE OF DEMAND FOR TRANSPORT CAPACITY SUPPLIERS. Through our
UIX databases, we are able to match our clients' demand with the available
capacity of transport suppliers. We represent a significant source of demand for
transport suppliers because we purchase a large volume of circuits. We believe
our transport suppliers consider us to be a valuable partner because we provide
them efficient access to the capacity requirements of our clients. We believe
that by working with us, transport suppliers can reduce their costs associated
with selling excess network capacity on existing routes to multiple buyers.

     ONGOING CLIENT SUPPORT. Our approach to client support involves developing
an understanding of our clients' business objectives, competitive environment,
market initiatives and service needs by maintaining close contact with our
clients through our Client Advocacy Services group. This group places highly
trained technical personnel in the field that are responsible for understanding
and rapidly responding to our clients' needs. Client Advocacy Services personnel
provide technical and administrative support during the circuit planning,
ordering, supply and installation processes and are available for ongoing
consultation.

OUR STRATEGY

     Our objective is to facilitate the creation of a seamlessly connected,
global communications network by improving the overall efficiency of the market
for network capacity and infrastructure services. To achieve this objective, we
intend to:

     CONTINUE TO ENHANCE INTERNET FUNCTIONALITY OF OUR UIX. We are currently
developing the infrastructure to provide an enhanced Internet interface that
will enable our clients to obtain price quotes, order circuits and receive
dedicated monitoring and support services, all in real time. We believe these
initiatives will enhance the efficiency and reliability of our web-based
services and will enable us to offer a more complete, electronic commerce
solution to our clients.

     CONTINUE TO EXPAND AND POPULATE OUR UIX DATABASES. We plan to continue to
gather data elements from our existing transport suppliers, including
information about pricing, capacity, availability, location and interconnection
information and other network elements for inclusion in our UIX databases. We
also plan to add information to our UIX on the networks of domestic and
international transport suppliers from whom we do not currently gather
information. We believe that our UIX databases provide us with a competitive
advantage and will become more difficult for a competitor to replicate as we
enhance the data and functionality of our UIX over time.

                                       37
<PAGE>   40

     CONTINUE TO DEVELOP UTX FACILITIES. We plan to continue to construct
additional UTX facilities in strategic locations within North America, Europe,
Asia and South America. In addition, we intend to construct UTX facilities that
are designed to meet the specific service requirements of major metropolitan
areas, regional sites and high occupancy buildings. We believe these facilities
will provide our clients a convenient and cost-effective method to interconnect
with multiple service providers and transport suppliers. We also believe that
our UTX facilities represent a platform for offering new services to our clients
and transport suppliers alike. For example, once a transport supplier places its
network in our UTX facility, the supplier may utilize our UTX services to
interconnect with other suppliers in that UTX facility to extend the geographic
coverage of its network.

     OPTIMIZE CIRCUIT CONFIGURATIONS TO GAIN EFFICIENCIES. We will use the
information available in our UIX and the extensive connections in our UTX
facilities to join discrete circuits between network access points. This will
allow us to optimize circuit configurations and realize network and economic
efficiencies.

     EXPAND INTERNATIONALLY. A number of international markets, such as Europe,
Asia and South America, have experienced deregulation similar to that in North
America and are therefore experiencing problems associated with fragmentation of
the network capacity market. We plan to offer our UIX, UTX and client support
services in international markets. We believe we can use our experience in the
U.S. market to achieve a competitive advantage by being one of the first to
address the network capacity constraints currently developing in international
markets. Given the high rates of interconnection between our clients and
emerging European suppliers, we believe that Europe represents our most
compelling international opportunity at this time.

     ENHANCE CAPABILITIES THROUGH ACQUISITIONS AND PARTNERSHIPS. We plan to
continue to acquire complementary businesses or technologies and to enter into
strategic partnerships. For example, in 1999 we completed two acquisitions to
expand and enhance the capabilities of our UIX databases.

SERVICES

     We offer our clients an integrated solution utilizing our UIX databases,
our UTX facilities and our client support services.

UNIVERSAL INFORMATION EXCHANGE (UIX)

     Our UIX consists of several proprietary, interconnected databases
containing capacity, availability, physical location and pricing information
from over 35 transport suppliers and more than 75,000 physical sites. The UIX
databases contain over 3.3 million data elements. We expect this number will
grow as we continue to add information to our UIX about the networks of new
transport suppliers. We offer our clients the ability to access information and
obtain services from our UIX using the Internet. By utilizing our UIX we are
able to provide our clients with a single point of contact for the supply and
installation of circuits from multiple vendors, as well as circuit access and
network monitoring. We believe our UIX enables us to provide these services more
efficiently and cost-effectively than traditional communications transport
suppliers.

     We utilize our UIX to offer our clients a comprehensive range of services
including:

     QUOTING. Our quoting system can be accessed over the Internet and enables
clients to request and receive quotes for circuit configuration, supply and
installation. We are generally able to provide a basic quote within 24 hours of
our clients' request.

     ORDER PROCESSING. Clients can place orders online by directly entering
information about their desired circuit, including capacity requirement,
physical location, contract terms, technical specifications and special
instructions.

                                       38
<PAGE>   41

     SUPPLY AND INSTALLATION OF CIRCUITS. Our UIX contains information on the
processes by which over 35 transport suppliers supply and install circuits. By
using this information we are able to work with the personnel and field
technicians of multiple vendors to provide dedicated circuits to our clients. As
part of our service we provide our clients with a graphical design layout record
showing critical network points and a weekly status update.

[In this space we will insert a diagram depicting representative circuit
segments (local loop, long haul, local loop) that could create a single
end-to-end circuit between end customers in New York City and San Francisco.]

     CIRCUIT ACCESS. We provide our clients with ongoing dedicated circuit
access over the networks of multiple vendors through long term contracts, with
terms typically ranging from 12 to 60 months. Our clients remit payment to us
for this ongoing circuit access on a monthly recurring basis for the life of the
contract.

     A circuit can be delivered at different speeds and capacities. We currently
are able to provide our clients circuit access at data rates ranging from DS-1
circuits carrying data at a rate of 1.536 million bits per second to OC-192
circuits carrying data at a rate of 192 OC-1 signals or 9.952 billion bits per
second.

     BILLING. We compile the costs of multiple vendor circuit segments and
present our clients with a single monthly invoice containing a single line item
for each service. This eliminates the need for our clients to process multiple
vendor bills and reduces our clients' processing time and costs.

     NETWORK MANAGEMENT SERVICES. We provide 24-hour-a-day, seven-day-a-week
network management services, offering a single point of contact for network
monitoring, maintenance and restoration across multiple vendor networks. Through
this single point of contact, we generate one client reference record of a
problem, which we use to provide network management across multiple vendor
networks and to provide our clients with reporting and trouble resolution. This
single client reference record increases response time and decreases down time
in a circuit outage.

     Our organization interacts with the network management organizations of our
transport suppliers, enabling us to identify and isolate circuit outages and to
facilitate their restoration throughout each segment of a circuit. Without these
services a client would have to contact multiple vendors to determine the source
of a circuit outage and to restore the circuit. Currently, our network
management services are partially outsourced through a third party until our own
facility becomes operational.

UNIVERSAL TRANSPORT EXCHANGE (UTX)

     Our UTX facilities provide interconnection points between multiple network
service providers and transport suppliers. Network service providers and
transport suppliers lease space in our facilities to place network equipment
that may be connected to other network service providers and transport suppliers
in the facility. Our UTX facilities may range in size from 500 square feet to
10,000 square feet.

     Our facilities do not depend on any particular technology and are open to
multiple competing network service providers and transport suppliers, such as
local exchange carriers, interexchange

                                       39
<PAGE>   42

carriers, competitive local exchange carriers, ISPs and ASPs. We are not aligned
with or reliant upon any single or group of transport suppliers. We believe that
our UTX clients are attracted to our neutral position, which both alleviates
their competitive concerns and provides them a broader range of solutions.

     As of March 7, 2000 we had two operational UTX facilities in Chicago and
Santa Clara, and five UTX facilities under construction in Dallas, Los Angeles,
Miami, San Francisco and Washington, D.C. We expect to commence construction on
eight additional facilities during 2000.

     Our UTX facilities are integrated with our UIX databases. Our UTX
facilities enable us to obtain additional information regarding available
network capacity and points of access that is entered into our UIX databases.
This additional information enables us to use our UIX databases more efficiently
to provide circuits and network monitoring services for our clients.

CLIENT SUPPORT SERVICES

     CLIENT ADVOCACY SERVICES. We provide high quality client support services
through our Client Advocacy Services organization. Our Client Advocacy Services
personnel are highly trained field representatives with extensive knowledge of
our services and an understanding of our client's business objectives. These
representatives team with both our sales and provisioning organizations to meet
client service expectations, and also provide technical assistance and field
support during circuit testing and installation.

     CARRIER DEVELOPMENT SERVICES. Our development services personnel are
responsible for managing our relationships with our existing transport suppliers
and for identifying new relationships.

SALES AND MARKETING

     Our sales and marketing efforts are focused on achieving broad market
penetration and increasing brand name recognition. Our sales efforts target
ISPs, telecommunications service providers and ASPs that we believe have the
greatest need for transport capacity and infrastructure services.

SALES

     We have developed a two-tiered sales strategy which is designed to (a)
target new accounts through our direct sales representatives and (b) identify
opportunities for additional sales to our existing client base through our
account managers. As of December 31, 1999 our sales staff consisted of 18 direct
sales representatives, including six account managers in 12 sales offices in the
United States, including offices in California, Virginia, New York and Illinois.
The direct sales force is divided into two geographic regions in the United
States and is supervised by regional directors, each of whom has responsibility
for all sales functions in his geographic region. The account management group
is supervised by a director and targets larger clients, based on recurring
monthly revenue.

     We have developed programs to attract and retain a highly skilled,
motivated sales staff that possesses the necessary technical skills,
consultative sales experience and knowledge of its assigned territory markets.
These programs include technical and sales process training and instruction in
consultative selling techniques. Our sales representatives and account managers
are compensated through a combination of base salary and performance-based
bonuses.

MARKETING

     We direct our corporate marketing efforts to a select market segment of
clients, including Internet service providers, application service providers and
telecommunications service providers. Our marketing activities include the
following:

     - Participation at telecommunication industry tradeshows where our clients
       and prospects are in attendance;

                                       40
<PAGE>   43

     - Advertising in telecommunications trade publications that target
       transport suppliers and service providers;

     - Direct mail campaigns that use tradeshow lists in order to attract the
       show's participants to our booth to learn about our current service
       offerings; and

     - Press releases about our services.

     We intend to increase marketing expenditures in future periods in an effort
to stimulate demand for our services and build brand awareness.

CLIENTS

     As of December 31, 1999, we had more than 100 clients, including
telecommunication services providers, Internet services providers and
application service providers. For the year ended December 31, 1999, AboveNet
Communications (MFN) accounted for 38% of our revenues. For the year ended
December 31, 1998, Carmen Associates accounted for approximately 16% of our
revenues and GTE Internetworking accounted for approximately 13% of our
revenues. The following is a list of all of our clients accounting for over 1%
of our monthly recurring revenues generated under client contracts as of
December 31, 1999:

AboveNet Communications (MFN)
AIT/PrePay Worldwide
Atlas Communications
BCE Nexxia
Business Technology Services
Cable & Wireless
CETLink
Electric Lightwave
Fiber Network Solutions
IDT
Internet Capital Group
InterXchange
Kivex
MegsInet
NapNet
Pathnet
Road Runner
Teleglobe Communications
UUNET

     Our client contracts generally provide for terms ranging from 12 to 60
months. Our clients may terminate their contracts at any time. However, a client
that cancels a contract is required to pay us substantially all of the amounts
payable over the remaining term of the contract. We bill for circuit charges
monthly in advance, and we recognize circuit revenues in the month that we
provide the service.


VENDORS



     From time to time we enter into long-term contracts, commonly referred to
as "master service agreements" or "master carrier agreements", with
communications transport suppliers for the supply and installation of network
capacity. As of March 10, 2000, we had master carrier agreements with the
following vendors:



AT&T


GTE


IXC (Broadwing)


Level(3) Communications


MCI Worldcom Communications


Williams Communications



     Our master carrier agreements generally provide for terms ranging from
three to ten years and provide for a monthly minimum revenue commitment for the
term of the contract. These master carrier agreements will impose minimum
purchase commitments on us that we anticipate will total approximately $1.8
million per month by September 2000. Under a master carrier agreement, each
circuit provided by a transport supplier has its own term, generally ranging
from 12 to 60 months, and is governed by the terms and conditions set forth in
the master carrier agreement. If we cancel a contract with a transport supplier
with respect to a particular circuit, we must generally pay cancellation charges
that can equal substantially all of the amount payable over the remaining term
of the contract for that circuit.

<PAGE>   44

COMPETITION

     The market for the services we provide is highly fragmented. We believe
that at this time no single competitor competes directly with us with respect to
all of the services we offer. However, we currently or potentially compete with
a variety of companies with respect to our services on an individual basis.
There are few substantial barriers to entry into our market, and we expect that
we will face additional competition from existing and new global entrants in the
future. We believe that any entrant in this market must grow rapidly and achieve
a significant presence in the market in order to compete effectively. We believe
that the principal competitive factors in this market include:

     - the ability to access information regarding multiple vendor networks;

     - the ability to provide connections to networks of multiple vendors;

     - the ability to provide comprehensive network management services
       including troubleshooting and circuit restoration across multiple network
       environments;

     - the ability to secure strategic relationships with carriers and clients;

     - the ability to provide a high level of ongoing client service and
       support;

     - the ability to locate interconnection facilities in strategic locations;
       and

     - brand recognition.

     We might not have the resources or expertise to compete successfully in the
future. For additional information on the competitive risks that we face, you
should read the section entitled "Risk Factors -- Competition in our industry is
intense and growing, and we may be unable to compete effectively".

INTELLECTUAL PROPERTY RIGHTS

     We rely on a combination of copyright, trademark, service mark and trade
secret laws and contractual restrictions to establish and protect proprietary
rights in our intellectual property. We have no patented technology that would
preclude or inhibit competitors from entering our market. We have no federally
registered trademarks or service marks, although we have applied for
registration of certain of our service marks. Even if registration is granted,
we may be limited in the scope of services for which we may exclusively use our
service marks. We enter into confidentiality agreements with our employees,
consultants and partners, and we control access to, and distribution of, our
proprietary information. Our intellectual property may be misappropriated or a
third party may independently develop similar intellectual property. Moreover,
the laws of certain foreign countries may not protect our intellectual property
rights to the same extent as do the laws of the United States. Unauthorized use
of any of our proprietary information could seriously harm our business.

GOVERNMENT REGULATION

     We plan to offer communications common carrier services that will be
subject to regulation by federal, state and local government agencies. Most data
and Internet services are not subject to regulation, although communications
services used for access to the Internet are regulated. We have obtained certain
federal and state regulatory authorizations for our regulated service offerings,
and are in the process of applying for additional authorizations.

     The FCC will exercise jurisdiction over our facilities and services to the
extent those facilities are used to provide, originate or terminate interstate
domestic or international common carrier communications. State regulatory
commissions will have jurisdiction over our services to the extent they are used
to originate or terminate intrastate common carrier communications.
Municipalities and other local government agencies may require carriers to
obtain licenses or franchises regulating use of public rights-of-way to install
and operate their networks. Many of the regulations issued by these regulatory
bodies may change and are the subject of various judicial proceedings,
legislative hearings and administrative proposals. In addition, federal, state
and local authorities may seek to tax the

                                       42
<PAGE>   45

services which we provide, which could impair the profitability of our business.
We cannot predict the results of any changes.

     As we expand our business to other countries, we will become subject to
similar regulatory issues in each country in which we do business. Although the
trend in regulation globally is towards less regulation of competitive
telecommunications markets, regulations in particular countries may limit our
service offerings or our ability to compete effectively.

FEDERAL REGULATION

     The FCC regulates us as a non-dominant communications common carrier. The
FCC's generally applicable regulations permit us to provide interstate domestic
common carrier services without any further authorization, and we also have
received authority from the FCC to provide international services between the
United States and foreign countries. Our interstate domestic and international
services are not subject to significant federal regulation, although we are
required to file schedules of our prices, terms, and conditions, or tariffs with
the FCC for our telecommunications services, and to pay regulatory fees and
assessments based on our interstate and international telecommunications
revenues. The FCC has the authority to condition, modify, cancel, terminate or
revoke our licenses and authorizations for failure to comply with federal laws
or the rules, regulations and policies of the FCC. The FCC may also impose fines
or other penalties for violations. The FCC also imposes prior approval
requirements on transfers of control and assignments of authorizations. While we
believe we are in compliance with applicable laws and regulations, we cannot
assure you that the FCC or third parties will not raise issues with regard to
our compliance.

     INTERNATIONAL SERVICES. The FCC has adopted rules for a multi-year
transition to lower international settlements payments by U.S. common carriers.
We believe that these rules are likely to lead to lower rates for certain
international services and increased demand for these services, including
capacity on the U.S. facilities that provide these services.

LOCAL COMPETITION RULES

     The FCC's role with respect to local telephone competition arises
principally from the Telecommunications Act of 1996. This Act preempts state and
local laws to the extent that they prevent competitive entry into the provision
of any telecommunications service and gives the FCC jurisdiction over important
issues related to local competition.

     Incumbent local exchange carriers (ILECs), such as the regional Bell
operating companies and affiliates of GTE and Sprint, are required to negotiate
in good faith with competing carriers on rates, terms and conditions for
interconnection, access to unbundled elements, resale, and other duties imposed
by the Telecommunications Act of 1996. The Telecommunications Act provides
procedures and timetables for negotiation, arbitration and approval of
interconnection agreements. Arbitration decisions involving interconnection
arrangements in several states have been challenged and appealed to Federal
courts. We may experience difficulty in obtaining timely implementation of local
interconnection agreements, and we can provide no assurance we will offer local
services in these areas in accordance with our projected schedule, if at all.

     The duties imposed on ILECs by the Telecommunications Act of 1996 include
the following:

     INTERCONNECTION. ILECs are required to provide interconnection for
competing local telecommunications carriers at any technically feasible point,
on rates, terms and conditions that are just, reasonable and nondiscriminatory.

     ACCESS TO UNBUNDLED ELEMENTS. ILECs are required to provide access to
network elements on an unbundled basis at any technically feasible point, on
rates, terms, and conditions that are just, reasonable, and nondiscriminatory.
On November 5, 1999, the FCC, in response to a recent U.S. Supreme Court
decision, released an Order revising its rules on the network elements that
incumbents must make available, particularly those used in the provision of
advanced services.

                                       43
<PAGE>   46

Among other things, this Order confirms that dedicated transport, including dark
fiber, is among the network elements that ILECs must provide on a unbundled
basis. A subsequent FCC order, released on December 9, 1999, requires ILECs to
unbundle the high-frequency portion of local access lines, so as to permit
competing carriers to offer broadband data services over the same copper wires
the ILEC uses to provide voice telephone service. While we do not believe that
these revisions will have significant impact on our business, other parties may
request an appeal of this Order, which will create continued uncertainty.

     COLLOCATION. ILECs are required to provide physical collocation of
equipment necessary for interconnection or access to unbundled network elements
at the ILEC's premises, except that the ILEC may offer alternative arrangements,
if it demonstrates to the state regulatory commission that physical collocation
is not practical for technical reasons, or because of space limitations. On
March 18, 1999, the FCC adopted measures designed to facilitate a competitor's
ability to access ILEC collocation space, including a requirement that ILECs
permit collocation without construction of a "cage" to enclose the competitor's
equipment, and a requirement that competitors be able to locate all equipment
necessary for interconnection, among other things.

     TRANSPORT AND TERMINATION CHARGES. ILECs and competitive local exchange
carriers (CLECs) must enter into reciprocal arrangements for transport and
termination of local telephone calls. State regulatory commissions, during
arbitrations, should set symmetrical prices for these services based on
forward-looking economic costs, using the Total Element Long Run Incremental
Cost, or TELRIC, methodology.

     PRICING METHODOLOGIES. State commissions are required to set arbitrated
rates for interconnection and unbundled elements based on the ILEC's TELRIC,
plus a reasonable share of forward-looking joint and common costs.

     RESALE. State commissions are required to identify which marketing,
billing, collection, and other costs will be avoided, or that are avoidable, by
ILECs when they provide services on a wholesale basis and to calculate the
portion of the retail rates for those services that is attributable to the
avoided and avoidable costs.

     ACCESS TO RIGHTS-OF-WAY. Telecommunications carriers and utilities are
required to provide nondiscriminatory access to their poles, ducts, conduits,
and rights-of-way.

     The Telecommunications Act of 1996 also eliminates previous prohibitions on
the provision of long distance services by the regional Bell operating companies
and GTE's telephone operating company subsidiaries. These companies are now
generally permitted to compete in providing long distance services, except that
the regional Bell operating companies are not allowed to provide long distance
service within the regions in which they also provide local exchange service,
known as "in-region service," until they receive specific approval of the FCC on
a state-by-state basis, based on satisfying several conditions, including a
checklist of requirements intended to open local telephone markets to
competition.

     In December 1999, the FCC authorized Bell Atlantic to provide in-region
long distance service in New York state. We expect that the FCC will consider
several other applications by regional Bell operating companies to provide
in-region services within the coming year. If the FCC permits regional Bell
operating companies to provide long distance service in their local service
regions before they meet our local interconnection needs, they would be able to
offer integrated local and long distance services and could have a significant
competitive advantage in marketing those services to their existing local
clients.

ILEC PRICING FLEXIBILITY

     In an Order issued in August 1999, the FCC granted the major local exchange
carriers increased pricing flexibility upon demonstration of increased
competition (or potential competition) in relevant markets. That process will
give ILECs progressively greater flexibility in setting rates as competition

                                       44
<PAGE>   47

develops, gradually replacing regulation with competition as the primary means
of setting prices. This ruling will permit the ILECs to charge different rates
for the same service in different geographic markets, and in some cases to
negotiate customer-specific price terms. Although currently under appeal at the
FCC and the District of Columbia Circuit Court, this FCC decision is likely to
have a significant impact on the interstate access prices charged by the ILECs
with which we compete, and hence on our operations, expenses, pricing and
revenue. The ILECs' prices for these services will affect us both directly, as a
customer buying services from the ILECs for resale to our customers, and
indirectly, as a competitor.

UNIVERSAL SERVICE REFORM

     On May 8, 1997, the FCC issued an order to implement the provisions of the
Telecommunications Act relating to the preservation of advancement of universal
telephone service. All telecommunications carriers providing interstate
telecommunications services, including us, must contribute to the universal
service support fund. These contributions became due beginning in 1998 for all
providers of interstate telecommunications services. Contributions are assessed
based on interstate and international end user telecommunications. Contribution
factors vary quarterly and carriers, including us, are billed monthly.

STATE REGULATION

     We will offer intrastate common carrier services and are subject to various
state laws and regulations. Most public utility commissions require some form of
certification or registration. We must acquire such authority before commencing
service. In most states, we are also required to file tariffs or price lists
setting forth the terms, conditions and prices for services that are classified
as intrastate. We are required to update or amend these tariffs when we adjust
our rates or add new products and are subject to various other regulatory
requirements, including payment of fees and filing of reports, in these states.

     Many states also require prior approval for transfers of control of
certified carriers, corporate reorganizations, acquisitions of
telecommunications operations, assignment of carrier assets, carrier stock
offerings and incurrence of significant debt obligations. Some states treat the
transfer of only 10% of the voting stock of a regulated company, or its parent
company, as a transfer of control that requires prior approval. The need to
obtain these approvals may delay, and therefore may affect the terms of, major
financing transactions in the future.

     States generally retain the right to sanction a carrier or to revoke
certification if a carrier violates relevant laws or regulations. If any state
regulatory agency were to conclude that we are or were providing intrastate
services without the appropriate authority, the agency could initiate
enforcement actions, which could include the imposition of fines, a requirement
to disgorge revenues, or the refusal to grant the regulatory authority necessary
for the future provision of intrastate communications services.

     We have applications pending to provide resold and network-based
competitive local exchange and interexchange services in many states and plan to
submit applications nationwide by the end of the year. We cannot be sure that we
will receive the authorizations we seek currently or in the future.

LOCAL GOVERNMENT AUTHORIZATIONS

     In some municipalities, we may be required to pay license or franchise fees
based on a percentage of gross revenue, as well as post performance bonds or
letters of credit. In many markets, the incumbent providers do not pay these
franchise fees or pay fees that are substantially less than those that we will
be required to pay. To the extent that competitors do not pay the same level of
fees as we do, we could be at a competitive disadvantage.

                                       45
<PAGE>   48

     At present, we have no plans to construct transmission facilities (such as
fiber optic lines) in public rights-of-way, but if we do so in the future we may
become subject to more extensive local government regulations.

INTERNATIONAL REGULATION

     In some countries where we plan to operate, local laws or regulations limit
or require prior government approval for the provision of international
telecommunications service in competition with authorized carriers. For example,
our provision of services over facilities using our own network or by purchasing
minutes from other carriers for resale to our customers may be affected by
increased regulatory requirements in a foreign jurisdiction. Also, local laws
and regulations differ significantly among the jurisdictions in which we operate
or plan to operate, and, within such jurisdictions, the interpretation and
enforcement of these laws and regulations can be unpredictable. We cannot be
sure that future regulatory, judicial, legislative or political changes will
permit us to offer to residents of these countries all or any of its services or
will not have a material adverse effect on us. In addition, we cannot be sure
that regulators or third parties will not raise material issues regarding our
compliance with applicable laws or regulations, or that governmental decisions
will not harm our business.

     In addition, the World Trade Organization Agreement, which reflects efforts
to eliminate government-owned telecommunications monopolies throughout Asia,
Europe and Latin America, may affect us. Although we believe that these
deregulation efforts will create opportunities for new entrants in the
telecommunications service industry, they also create enhanced opportunities for
foreign telecommunications carriers to compete against us.

LEGAL PROCEEDINGS


     In February 2000, a complaint was filed in the Superior Court of
California, County of Santa Clara, against us and other parties by Point West
Ventures, L.P., previously known as Fourteen Hill Capital, L.P. and certain
other shareholders in Vaultline Incorporated. The claim arises out of a letter
of intent that we entered into in December 1998 relating to our potential
acquisition of Vaultline. The letter stated that it was not binding on the
parties except with respect to a $250,000 advance to be made by us and certain
obligations of Vaultline. The letter contemplated that we would undertake a due
diligence investigation of Vaultline. After performing the due diligence, we
determined not to complete the transaction and entered into a mutual settlement
agreement and release. Subsequently, Vaultline ceased doing business. The
claimants contend that the mutual settlement agreement executed by the president
of Vaultline was unauthorized. They allege that we, certain of our officers and
others conspired to deprive them of their interests in Vaultline. They are
seeking damages in excess of $10,000,000. We believe all of our legal
obligations were satisfied and intend to vigorously contest any claims asserted
against us relating to this matter.


EMPLOYEES


     As of March 13, 2000, we had approximately 250 full-time employees, none of
whom was represented by a labor union. Our future performance depends, in
significant part, upon the continued service of our key technical, sales and
senior management personnel. All of our executive officers are subject to
employment agreements for specific terms. For additional information on these
employment agreements, please see "Management -- Employment Agreements" and
"-- Change of Control Agreements". The loss of the services of one or more of
our key employees could have a material adverse effect on our business,
financial condition and results of operations. To date, we have not experienced
any work stoppages, and we consider our relations with our employees to be good.

FACILITIES

     Our headquarters are located in Chicago, Illinois, where we lease 32,142

BOARD OF DIRECTORS

be divided into three classes: Class I, whose terms will expire at the annual
meeting of stockholders to be held in 2000; Class II, whose term will expire at
the annual meeting of stockholders to be held in 2001; and Class III, whose term
will expire at the annual meeting of the stockholders to be held in 2002. This
classification of our board of directors may delay or prevent a change in
control of our company or in our management. See "Description of Capital
Stock -- Delaware Anti-Takeover Law and Certain Charter and Bylaw Provisions".


     Our executive officers are appointed by our board of directors on an annual
basis and serve until their successors have been elected and qualified. There
are no family relationships among any of our directors, officers or key
employees.

BOARD COMMITTEES

     We established an audit committee and a compensation committee in August
1999. The audit committee consists of Messrs. Slevin, Schocken and Van der Meer.
The audit committee reviews our internal accounting procedures and consults with
and reviews the services provided by our independent accountants.

     The compensation committee consists of Messrs. Kapsalis, Schocken and Van
der Meer. The compensation committee reviews and recommends to our board of
directors the compensation of all of our officers and directors, including stock
compensation and loans and establishes and reviews general policies relating to
the compensation and benefits of our employees.

                                       50
<PAGE>   53

     We established an option committee consisting of Messrs. Pommer, Schocken,

equity grants pursuant to our stock option plans to our employees other than
executive officers.

     We established a nominating committee in February 1999, consisting of

appointment of directors to our board of directors.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION


     The members of our compensation committee are Messrs. Kapsalis, Schocken
and Van der Meer. None of the members of the compensation committee is currently
or has been, at any time since our formation, one of our officers or employees.
None of our executive officers currently serves or in the past has served as a
member of the board of directors or compensation committee of any entity that
has one or more executive officers serving on our board or compensation
committee. Mr. Kapsalis is a holder of approximately 4.84% of our outstanding
stock. He is also principal of K&D Consulting. We paid K&D Consulting $3,000 per
month from April 1999 to October 1999 for management consulting services. Mr.
Van der Meer is a partner of ComVentures, a holder of approximately 17.02% of
our outstanding stock that has purchased shares of Series B preferred stock,
Series C preferred stock and Series D preferred stock. Mr. Schocken is the
chairman of Broadmark Capital Corporation, a holder of approximately 1.02% of
our outstanding stock that has purchased shares of our common stock, Series A
preferred stock and Series D preferred stock. Broadmark Capital Corporation
provided financial services to us in connection with the placement of our Series
A preferred stock and Series D preferred stock. As consideration for these
services, we paid Broadmark approximately $502,190 and issued them warrants for
our common stock and our Series A preferred stock. In addition, Broadmark
received options to purchase a total of 839,994 shares of our common stock from
John Drummond, a 5% stockholder, Thomas Kapsalis, a 5% stockholder and a
director, and another stockholder. See "Transactions with Related Parties and
Insiders." Prior to the formation of the compensation committee, compensation
decisions were made by our entire board of directors.


DIRECTOR COMPENSATION

     Other than our stock option grant to Paolo Guidi in August 1999 which is
described in "Transactions With Related Parties and Insiders -- Option Grants to
Executive Officers and Directors" and the payment of $2,000 to Mr. Guidi for
each board meeting that he attends in person or by telephone, we do not
currently compensate our directors in cash for their service as members of our
board of directors, although they are reimbursed for certain expenses in
connection with attendance at board of director and committee meetings. Our 1999
Director Option Plan provides for the automatic grant of non-statutory stock
options to nonemployee directors. For further information regarding the
provisions of the 1999 Director Option Plan, see "-- Incentive Stock Plans".

LIMITATIONS ON DIRECTORS' LIABILITY AND INDEMNIFICATION

     Our certificate of incorporation will, upon the closing of this offering,
limit the liability of directors to the maximum extent permitted by Delaware
law. Delaware law provides that directors of a corporation will not be
personally liable for monetary damages for breach of their fiduciary duties as
directors, except liability for:

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

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

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

     - any transaction from which the director derived an improper personal
       benefit.
                                       51
<PAGE>   54

     The limitation of liability does not apply to liabilities arising under the
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission.

     Our certificate of incorporation and bylaws provide that we will indemnify
our directors and officers and may indemnify our employees and other agents to
the fullest extent permitted by law. We believe that indemnification under our
bylaws covers at least negligence on the part of indemnified parties. Our bylaws
also permit us to secure insurance on behalf of any officer, director, employee
or other agent for any liability arising out of his or her actions in their
capacity as an officer, director, employee or other agent, regardless of whether
the bylaws would permit indemnification.

     We have entered into agreements to indemnify our directors and executive
officers, in addition to the indemnification provided for in our bylaws. These
agreements, among other things, provide for indemnification for judgments,
fines, settlement amounts and certain expenses, including attorneys' fees
incurred by the director, executive officer or controller in any action or
proceeding, including any action by or in our right, arising out of the person's
services as a director, executive officer or controller of us, any of our
subsidiaries or any other company or enterprise to which the person provides
services at our request. We believe that these provisions and agreements are
necessary to attract and retain qualified persons as directors and executive
officers.

     The limited liability and indemnification provisions in our certificate of
incorporation and bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful, might otherwise benefit us and our
stockholders. A stockholder's investment in us may be adversely affected to the
extent we pay the costs of settlement or damage awards against our directors and
officers under these indemnification provisions.

     At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees in which indemnification is sought, nor are
we aware of any threatened litigation that may result in claims for
indemnification.

EXECUTIVE COMPENSATION

     The following table sets forth the compensation earned, awarded or paid for
services rendered to us in all capacities for the fiscal year ended December 31,
1999 by our Chief Executive Officer and our next four most highly compensated
executive officers who earned more than $100,000 in salary and bonus during the
fiscal year ended December 31, 1999, whom we refer to in this prospectus
collectively as the "named executive officers":

OPTION GRANTS IN LAST FISCAL YEAR

     The following table shows information regarding stock options granted to
the named executive officers during the fiscal year ended December 31, 1999. The
potential realizable value is based on the assumption that our common stock
appreciates at the annual rate shown, compounded annually, from the date of
grant until the expiration of the ten-year term. These numbers are calculated
based on Securities and Exchange Commission requirements and do not reflect
projections or estimates of future stock price growth. Potential realizable
values are computed by:

     - Multiplying the number of shares of common stock underlying each option
       by $9.00 per share, the assumed initial public offering price per share;

     - Assuming that the total stock value derived from that calculation
       compounds at the annual 0%, 5% or 10% rate shown in the table for the
       entire ten-year term of the option; and

     - Subtracting from that result the total option exercise price.

     Actual gains, if any, on stock option exercises will be dependent on the
future performance of our common stock.

     The percentage of total options granted is based on an aggregate of
7,131,250 options granted by us during the fiscal year ended December 31, 1999,
to our employees including the named executive officers. Unless otherwise
indicated, options were granted with an exercise price equal to the fair market
value of our common stock, as determined in good faith by our board of directors
at the time of the grants.

of directors, minus the per share exercise price, multiplied by the number of
shares underlying the option.

INCENTIVE STOCK PLANS

1998 EMPLOYEE STOCK OPTION PLAN

     Our 1998 Employee Stock Option Plan, referred to as the "1998 Plan", was
adopted by our board of directors on July 10, 1998 and approved by our
stockholders on May 1, 1998. Our board of directors has decided that as of the
effective date of this offering no further options will be granted under the
1998 Plan. However, the provisions of our 1998 Plan will continue to govern
outstanding options issued under the 1998 Plan. Our 1998 Plan provides for the
grant of incentive stock options, within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended, referred to as the "Code", to our
employees and for the grant of nonstatutory stock options to our employees,
directors and consultants.


     NUMBER OF SHARES OF COMMON STOCK AVAILABLE UNDER THE 1998 PLAN. The maximum
number of shares that may be issued under the 1998 Plan is 13,000,000 shares of
our common stock. As of March 10, 2000 options to purchase 10,688,179 shares of
our common stock were outstanding under the 1998 Plan.


     ADMINISTRATION OF THE 1998 PLAN. Our board of directors or a committee
appointed by our board of directors administers the 1998 Plan. The board or
committee has the authority to determine the terms of the option grants under
the 1998 Plan including the exercise price, the number of shares covered by each
option, the vesting of options and the form of consideration payable upon
exercise.

     OPTIONS. The exercise price of incentive stock options granted under the
1998 Plan may not be lower than the fair market value, as determined by our
board of directors on the date of grant, of our common stock and the term of an
option may not exceed 10 years. If one of our stockholders owned 10% of the
voting power of all classes of our outstanding capital stock and is granted an
incentive stock option, the exercise price may not be lower than 110% of the
fair market value on the date of grant and the term may be no longer than five
years.

     If an optionee's employment is terminated due to death or disability, he or
she generally will have one year to exercise any of his or her outstanding
options. If an optionee's employment is terminated due to retirement, he or she
generally will have three years to exercise each outstanding option. If an

                                       55
<PAGE>   58

optionee's employment is terminated for any other reason, he or she generally
will have three months to exercise any options held by him or her; provided,
however an optionee's options will terminate immediately upon his or her
termination for cause.

     Options granted under our 1998 Plan are not transferable other than by
will, the laws of inheritance or pursuant to a qualified domestic relations
order.

     ADJUSTMENTS UPON MERGER OR ASSET SALE. Our 1998 Plan provides that if we
merge with or into another corporation or sell substantially all of our assets,
the successor corporation will assume or substitute each option. If the
outstanding options are not assumed or substituted by the successor corporation,
the committee has the discretion to allow each option to be exercisable in full,
including shares that would not otherwise be exercisable at the time of such
merger or sale of assets. If the outstanding options are not assumed or
substituted by the successor corporation and the committee chooses to accelerate
the exercisability of outstanding options, all options will terminate if not
exercised during the 30-day period prior to the merger or sale of assets.

1999 STOCK PLAN

     Our board of directors adopted the 1999 Stock Plan, referred to as the
"1999 Plan", in November 1999. The 1999 Plan was approved by our stockholders in
January 2000. Our 1999 Plan provides for the grant of incentive stock options,
within the meaning of Section 422 of the Code, to our employees, and for the
grant of nonstatutory stock options and stock purchase rights to our employees,
directors and consultants.


     NUMBER OF SHARES OF COMMON STOCK AVAILABLE UNDER THE 1999 PLAN. As of March
10, 2000, a total of 10,000,000 shares of our common stock were reserved for
issuance pursuant to the 1999 Plan, of which options to acquire 623,750 shares
were issued and outstanding as of that date. We anticipate that we will grant
approximately 475,000 additional shares under our 1999 Plan prior to the closing
of this offering. Our 1999 Plan provides for annual increases in the number of
shares available for issuance under our 1999 Plan on the first day of each
fiscal year, beginning with our fiscal year 2001, equal to the lesser of 5% of
the outstanding shares of common stock on the first day of our fiscal year,
10,000,000 shares of our common stock, or an amount determined by our board of
directors.


     ADMINISTRATION OF THE 1999 PLAN. Our board of directors or a committee of
our board of directors administers the 1999 Plan. In the case of options
intended to qualify as "performance-based compensation" within the meaning of
Section 162(m) of the Code, the committee will consist of two or more "outside
directors" within the meaning of Section 162(m) of the Code. The administrator
has the authority to determine the terms of the options or stock purchase rights
granted, including the exercise price, the number of shares subject to each
option or stock purchase right, the exercisability of the options and the form
of consideration payable upon exercise.

     OPTIONS. The administrator determines the exercise price of options granted
under the 1999 Plan, but with respect to nonstatutory stock options intended to
qualify as "performance-based compensation" within the meaning of Section 162(m)
of the Code and all incentive stock options, the exercise price must at least be
equal to the fair market value of our common stock on the date of the grant. The
term of an incentive stock option may not exceed ten years, except that with
respect to any participant who owns 10% of the voting power of all classes of
our outstanding capital stock, the term must not exceed five years and the
exercise price must equal at least 110% of the fair market value on the grant
date. The administrator determines the term of all other options.

     No optionee may be granted an option to purchase more than 3,000,000 shares
in any fiscal year; except that an optionee in his initial term of service may
receive options to purchase up to an additional 2,000,000 shares.

     After termination of the employment of one of our employees, directors or
consultants, he or she may exercise vested options for the period of time
subsequent to termination stated in the option

                                       56
<PAGE>   59

agreement or for three months if a period is not stated in the option agreement.
If termination of employment is due to death or disability, vested options will
remain exercisable for 12 months or for the period stated in the option
agreement. However, an option may never be exercised later than the expiration
of its term.

     STOCK PURCHASE RIGHTS. Stock purchase rights, which represent the right to
purchase our common stock, may be issued under our 1999 Plan. The administrator
determines the exercise price of stock purchase rights granted under our 1999
Plan. Unless the administrator determines otherwise, a restricted stock purchase
agreement, an agreement between us and an optionee which governs the terms of
stock purchase rights, will grant us a repurchase option that we may exercise
upon the voluntary or involuntary termination of the purchaser's service with us
for any reason, including death or disability. The purchase price for shares we
repurchase will generally be the original price paid by the purchaser and may be
paid by cancellation of any indebtedness of the purchaser to us. The
administrator determines the rate at which our repurchase option will lapse.

     TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS. Our 1999 Plan
generally does not allow for the transfer of options or stock purchase rights,
and, during the lifetime of the optionee, only the optionee may exercise an
option and stock purchase right. However, the administrator has the authority to
allow for the transferability of options and stock purchase rights.

     ADJUSTMENTS UPON MERGER OR ASSET SALE. Our 1999 Plan provides that if we
merge with or into another corporation or sell substantially all of our assets,
the successor corporation will assume or substitute each option or stock
purchase right. If the outstanding options or stock purchase rights are not
assumed or substituted, the administrator will provide notice to the optionee
that he or she has the right to exercise the option or stock purchase right as
to all of the shares subject to the option or stock purchase right, including
shares which would not otherwise be exercisable, for a period of 15 days from
the date of the notice. The option or stock purchase right will terminate upon
the expiration of the 15-day period provided for in the notice.

     AMENDMENT AND TERMINATION OF OUR 1999 PLAN. Our 1999 Plan will
automatically terminate in 2009, unless our board of directors terminates it
sooner. However, our board of directors may amend, suspend or terminate the 1999
Plan provided it does not adversely affect any option previously granted under
our 1999 Plan.

1999 EMPLOYEE STOCK PURCHASE PLAN

     Concurrently with this offering, we intend to establish an employee stock
purchase plan. The employee stock purchase plan was adopted by our board in
November 1999 and was approved by our stockholders in January 2000.

     NUMBER OF SHARES OF COMMON STOCK AVAILABLE UNDER THE PURCHASE PLAN. A total
of 500,000 shares of our common stock will be made available for issuance under
the employee stock purchase plan. In addition, our employee stock purchase plan
provides for annual increases in the number of shares available for issuance
under the employee stock purchase plan on the first day of each fiscal year,
beginning with our fiscal year 2001, equal to the lesser of 2% of the
outstanding shares of our common stock on the first day of the fiscal year,
3,000,000 shares, or such other amount as our board of directors may determine.

     ADMINISTRATION OF THE PURCHASE PLAN. Our board of directors or a committee
of our board administers the employee stock purchase plan. Our board of
directors or its committee has full and exclusive authority to interpret the
terms of the employee stock purchase plan.

     ELIGIBILITY TO PARTICIPATE. Our employees are eligible to participate if
they are customarily employed by us or any participating subsidiary for at least
20 hours per week and more than five

                                       57
<PAGE>   60

months in any calendar year. However, an employee may not be granted an option
to purchase stock under the employee stock purchase plan if such employee:

     - immediately after grant will own stock possessing 5% or more of the total
       combined voting power or value of all classes of our capital stock, or

     - has rights to purchase stock under any of our employee stock purchase
       plans that accrue at a rate that exceeds $25,000 worth of stock for each
       calendar year.

     OFFERING PERIODS AND CONTRIBUTIONS. Our employee stock purchase plan is
intended to meet the requirements of Section 423 of the Internal Revenue Code
and contains consecutive, overlapping 24-month offering periods. Each offering
period includes four 6-month purchase periods. The offering periods generally
start on the first trading day on or after May 1st and November 1st of each
year, except for the first such offering period which will commence on the first
trading day on or after the effective date of this offering and will end on the
last trading day on or before April 30, 2002.

     Our employee stock purchase plan permits participants to purchase common
stock through payroll deductions of up to 15% of their eligible compensation
which includes a participant's base salary, wages, overtime pay, commissions,
bonuses and other compensation remuneration paid directly to the employee. A
participant may not purchase more than 3,000 shares during a six month purchase
period.

     PURCHASE OF SHARES. Amounts deducted and accumulated by the participant are
used to purchase shares of our common stock at the end of each six-month
purchase period. The price is 85% of the lower of the fair market value of our
common stock at the beginning of an offering period or at the end of a purchase
period. If the fair market value at the end of a purchase period is less than
the fair market value at the beginning of the offering period, participants will
be withdrawn from the current offering period following their purchase of shares
on the purchase date and will be automatically re-enrolled in a new offering
period. Participants may end their participation at any time during an offering
period, and will be paid their payroll deductions to date. Participation ends
automatically upon termination of employment with us.

     TRANSFERABILITY OF RIGHTS. A participant may not transfer rights granted
under the employee stock purchase plan other than by will, the laws of descent
and distribution or as otherwise provided under the employee stock purchase
plan.

     ADJUSTMENTS UPON MERGER OR ASSET SALE. If we merge with or into another
corporation or sell substantially all of our assets, a successor corporation may
assume or substitute each outstanding option. If the successor corporation
refuses to assume or substitute for the outstanding options, the offering period
then in progress will be shortened, and a new exercise date will be set.

     AMENDMENT AND TERMINATION OF THE PURCHASE PLAN. Our employee stock purchase
plan will terminate in 2009. However, our board of directors may at any time and
for any reason amend or terminate our employee stock purchase plan, except that,
subject to certain exceptions described in the employee stock purchase plan, no
such action may adversely affect any outstanding rights to purchase stock under
our employee stock purchase plan.

1999 DIRECTOR OPTION PLAN

     Our board of directors adopted the 1999 Director Option Plan in November
1999. The director plan was approved by to our stockholders in January 2000. The
director plan provides for the periodic grant of nonstatutory stock options to
our non-employee directors.

     NUMBER OF SHARES AVAILABLE UNDER THE DIRECTOR PLAN. As of December 31,
1999, a total of 500,000 shares were reserved for issuance under the director
plan. No options will be granted under the director plan until the effective
date of this offering.

                                       58
<PAGE>   61

     OPTIONS. All grants of options to our non-employee directors under the
director plan are automatic. We will grant each non-employee director an option
to purchase 20,000 shares upon the later of (i) the effective date of the
director plan, or (ii) when such person first becomes a non-employee director;
however those directors who became non-employee directors by ceasing to be
employee directors will not receive such an option grant. All non-employee
directors who have been a director for at least six months as of June 30th of
each year will receive an option to purchase 5,000 shares on June 30th of each
year.

     All options granted under our director plan have a term of ten years and an
exercise price equal to fair market value on the date of grant. Each
20,000-share option becomes exercisable as to 25% of the shares subject to the
option on each anniversary of the date of grant, provided the non-employee
director remains a director on such dates. Each annual 5,000-share option
becomes exercisable as to 100% of the shares subject to the option on the first
anniversary of the date of grant, provided the non-employee director remains a
director on such date.

     After termination as a non-employee director, an optionee must exercise an
option within the time set forth in his or her option agreement. If termination
is due to death or disability, the option will remain exercisable for 12 months.
In all other cases, the option will remain exercisable for a period of three
months. However, an option may never be exercised later than the expiration of
its term.

     TRANSFERABILITY OF OPTIONS. A non-employee director may not transfer
options granted under our director plan other than by will or the laws of
descent and distribution. Only the non-employee director may exercise the option
during his or her lifetime.

     ADJUSTMENTS UPON MERGER OR AN ASSET SALE. If we merge with or into another
corporation or sell substantially all of our assets, the successor corporation
will assume or substitute each option. If such assumption or substitution
occurs, the options will continue to be exercisable according to the same terms
as before the merger or sale of assets. Following such assumption or
substitution, if a non-employee director is terminated other than by voluntary
resignation, the option will become fully exercisable, including as to shares
for which it would not otherwise be exercisable and generally will remain
exercisable for a period of three months. If the outstanding options are not
assumed or substituted for, our board of directors will notify each non-employee
director that he or she has the right to exercise the option as to all shares
subject to the option for a period of 30 days following the date of the notice.
The option will terminate upon the expiration of the 30-day period.

     AMENDMENT AND TERMINATION OF THE DIRECTOR PLAN. Unless terminated sooner,
our director plan will automatically terminate in 2009. Our board of directors
may amend, alter, suspend, or discontinue the director plan, but no such action
may adversely affect any grant made under the director plan.

401(k) PLAN

     In 1999, we adopted the Universal Access, Inc. 401(k) Savings Plan and
Trust, covering our eligible full-time employees located in the United States.
The 401(k) plan is intended to meet the requirements of Sections 401(a) and
401(k) of the Internal Revenue Code, as amended, so that contributions to the
401(k) plan by employees, and the investment earnings thereon, are not taxable
to employees until withdrawn from the 401(k) plan. Under the 401(k) plan,
employees may elect to reduce their current eligible compensation by up to the
lesser of 15% of their annual compensation or the statutorily prescribed annual
limit ($10,500 in 2000) and to have the amount of the reduction contributed to
the 401(k) plan. The 401(k) plan does permit discretionary matching
contributions to the 401(k) plan by us on behalf of participants in the 401(k)
plan who have completed at least a year of service to us. To date, there have
been no matching contributions.

                             PRINCIPAL STOCKHOLDERS


     The following table sets forth information regarding the beneficial
ownership of our common stock as of March 10, 2000, and as adjusted to reflect
the sale of common stock offered by this prospectus, by:


     - each of the individuals listed on the "Summary Compensation Table" above;

     - each of our directors;

     - each person (or group of affiliated persons) who is known by us to own
       beneficially 5% or more of our common stock; and

     - all current directors and executive officers as a group.


     Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. In computing the number of shares
beneficially owned by a person and the percentage ownership of that person,
shares of common stock subject to options held by that person that are currently
exercisable or exercisable within 60 days of March 10, 2000, are deemed issued
and outstanding. These shares, however, are not deemed outstanding for purposes
of computing percentage ownership of each other stockholder.


     Except as indicated in the footnotes to this table and subject to
applicable community property laws, each stockholder named in the table has sole
voting and investment power with respect to the shares shown as beneficially
owned by them. This table also includes shares owned by a spouse as community
property.


     Percentage of ownership is based on 76,460,616 shares of common stock
outstanding on March 10, 2000 and 87,460,616 shares of common stock outstanding
after completion of this offering. The percentage of common stock outstanding as
of March 10, 2000 is calculated in accordance with the rules of the Securities
and Exchange Commission and assumes, for purposes of this calculation, that all
outstanding preferred stock has been converted into common stock. This table
assumes no exercise of the underwriters' over-allotment option. Unless otherwise
indicated, the address of each of


                                       67

the individuals named below is: c/o Universal Access, Inc., 100 North Riverside

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     We are authorized to issue 1,000,000,000 shares of common stock, $0.01 par
value, and 20,000,000 shares of undesignated preferred stock, $0.01 par value.
The following description of our capital stock does not purport to be complete
and is subject to and qualified by our certificate of incorporation and amended
and restated bylaws, which are included as exhibits to the Registration
Statement of which this prospectus forms a part, and by the provisions of
applicable Delaware law.

COMMON STOCK


     As of March 10, 2000, there were 76,460,616 shares of common stock
outstanding, as adjusted to reflect the conversion of all outstanding shares of
preferred stock into common stock (assuming no adjustment to the Series E
preferred stock conversion ratio as discussed below), which were held of record
by approximately 228 stockholders.


     Our Amended Certificate of Designations provides that each share of Series
E preferred stock will be initially convertible into three shares of common
stock upon the completion of this offering. However, the Series E conversion
ratio for the Series E preferred stock will be multiplied by the lesser of 3.75
and X, where X equals the greater of (A) 1 or (B) the quotient obtained by
dividing (i) $750,000,000 by (ii) the product of (x) the number of shares of
common stock outstanding immediately before this offering is completed (on a
fully diluted and as converted basis, without taking into account additional
shares of common stock that would be issuable to Series E preferred stock as a
result of this adjustment) and (y) the initial public offering price per share
in this offering.

     The following examples illustrate the effect that this adjustment to the
Series E preferred stock's conversion ratio would have on the number of shares
of our common stock outstanding upon completion of this offering, based on the
87,218,414 shares of common stock outstanding on an as-converted and
fully-diluted basis as of December 31, 1999:

     - If the initial public offering price per share is $9.00 (the midpoint of
       the assumed range as set forth in this prospectus), no adjustment would
       be made to the conversion ratio. As a consequence, each share of Series E
       preferred stock would be convertible into three shares of common stock,
       and we would have an aggregate of 85,809,264 shares of common stock
       outstanding upon completion of this offering.

     - If the initial public offering price per share is $8.60 or greater, no
       adjustment would be made to the conversion ratio. As a consequence, each
       share of Series E preferred stock would be convertible into three shares
       of common stock, and we would have an aggregate of 85,809,264 shares of
       common stock outstanding upon completion of this offering.

     - If the initial public offering price per share is $2.29 or less, then the
       conversion ratio would be multiplied by 3.75. As a consequence, each
       share of Series E preferred stock would be convertible into 11.25 shares
       of common stock, and we would have an aggregate of 98,657,690 shares of
       common stock outstanding upon completion of this offering.

     The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the board of directors out of funds legally available for that
purpose. See "Dividend Policy". In the event of a liquidation, dissolution or
winding up of Universal Access, the holders of common stock are entitled to
share ratably in all assets remaining after payment of liabilities, subject to
prior distribution rights of preferred stock, if any, then outstanding. The
common stock has no preemptive or conversion rights or other subscription
rights. There are no redemption or sinking fund provisions applicable to the
common stock. All outstanding shares of common stock are

                                       70
<PAGE>   73

fully paid and nonassessable, and the shares of common stock to be issued upon
the closing of this offering will be fully paid and nonassessable.

PREFERRED STOCK

     The board of directors has the authority, without action by the
stockholders, to designate and issue preferred stock in one or more series and
to designate the rights, preferences and privileges of each series, any or all
of which may be greater than the rights of the common stock. We cannot state the
actual effect of the issuance of any shares of preferred stock upon the rights
of holders of the common stock until the board of directors determines the
specific rights of the holders of the preferred stock. However, the effects
might include, among other things, restricting dividends on the common stock,
diluting the voting power of the common stock, impairing the liquidation rights
of the common stock and delaying or preventing a change in control of Universal
Access without further action by the stockholders. We have no present plans to
issue any shares of preferred stock.

WARRANTS


     At March 10, 2000, there were the following warrants outstanding:



     - a warrant to purchase a total of 1,000,002 shares of common stock which
       will expire on February 8, 2004, unless earlier exercised; and



     - a warrant to purchase a total of 120,000 shares of common stock (assuming
       no adjustment to the Series E preferred stock conversion ratio) which
       will expire on November 10, 2004, unless earlier exercised.


     All five of these warrants will remain outstanding after the completion of
this offering and may be exercised on a "net" basis. If a warrant is exercisable
on a "net" basis, instead of paying the exercise price in cash, the holder may
instruct us to retain a number of shares that has a fair market value at the
time of exercise equal to the aggregate exercise price.

REGISTRATION RIGHTS


     As of March 10, 2000 the holders of 39,634,614 shares of common stock, as
converted, and the holders of warrants and options to purchase 1,959,996 shares
of common stock, as converted, or their permitted transferees are entitled to
certain rights with respect to registration under the Securities Act of the
shares held by them at any time after 180 days following the closing of this
offering. Subject to limitations specified in the agreements, these registration
rights include the following:


     - Piggyback Registration Rights: We must allow the holders of registrable
       securities to register all or, any portion of the holder's registrable
       securities concurrently with any registration statement we file. These
       rights are subject to the right of the underwriter to reduce the number
       of shares proposed to be registered in view of market conditions.

     - S-3 Registration Rights: The holders of at least twenty percent of the
       then outstanding registrable securities may require us to register all or
       a portion of their registrable securities on Form S-3 when use of this
       form becomes available to us.

     - Demand Registration Rights: If at any time prior to February 5, 2007, we
       receive a registration request from at least a majority of the holders of
       Series B and Series D preferred stock who have registration rights, then
       we must prepare, file and use our best efforts to effect up to two
       registration statements.

     We will bear all registration expenses other than underwriting discounts
and commissions for holders exercising piggyback rights and S-3 registration
rights.

DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS

     Certain provisions of Delaware law and our certificate of incorporation and
bylaws could make it more difficult to acquire us by means of a tender offer, a
proxy contest or otherwise to remove incumbent officers and directors. These
provisions, summarized below, are expected to discourage certain types of
coercive takeover practices and inadequate takeover bids and to encourage
persons seeking to acquire control of us to first negotiate with us. We believe
that the benefits of our potential ability to negotiate with the proponent of an
unfriendly or unsolicited proposal to acquire or restructure us outweigh the
disadvantages of discouraging takeover or acquisition proposals because, among
other things, negotiation of these proposals could result in an improvement of
their terms.

     We are subject to Section 203 of the Delaware General Corporation Law, an
anti-takeover law. In general, Section 203 prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years following the date the person became an
interested stockholder, unless (with certain exceptions) the "business
combination" or the transaction in which the person became an interested
stockholder is approved in a prescribed manner. Generally, a "business
combination" includes a merger, asset or stock sale, or other transaction
resulting in a financial benefit to the interested stockholder. Generally, an
"interested stockholder" is a person who, together with affiliates and
associates, owns (or within three years prior to the determination of interested
stockholder status, did own) 15% or more of a corporation's voting stock. The
existence of this provision would be expected to have an anti-takeover effect
with respect to transactions not approved in advance by the board of directors,
including discouraging attempts that might result in a premium over the market
price for the shares of common stock held by stockholders.

     Our certificate of incorporation and bylaws require that any action
required or permitted to be taken by our stockholders must be effected at a duly
called annual or special meeting of the stockholders and may not be effected by
a consent in writing. In addition, special meetings of our stockholders may be
called only by the board of directors or certain of our officers. Our
certificate of incorporation and bylaws also provide that, beginning upon the
closing of this offering, our board of directors will be divided into three
classes, with each class serving staggered three-year terms, and that certain
amendments of the certificate of incorporation and of the bylaws require the
approval of holders of at least 66 2/3% of the voting power of all outstanding
stock. These provisions may have the effect of deterring hostile takeovers or
delaying changes in control or management of Universal Access.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is Norwest
Shareholder Services.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Immediately prior to this offering, there was no public market for our
common stock. Future sales of substantial amounts of common stock in the public
market could adversely affect the market price of the common stock.


     Upon completion of this offering, we will have outstanding 87,460,616
shares of common stock, assuming the issuance of 11,000,000 shares of common
stock offered by us and no exercise of options after March 10, 2000, and
assuming no exercise of the underwriters' option to purchase additional shares
in the offering. All of the 11,000,000 shares sold in this offering will be
freely tradable without restriction or further registration under the Securities
Act; provided, however, that if shares are purchased by "affiliates" as that
term is defined in Rule 144 under the Securities Act, their sales of shares
would be subject to certain limitations and restrictions that are described
below.



     The remaining 76,460,616 shares of common stock held by existing
stockholders were issued and sold by us in reliance on exemptions from the
registration requirements of the Securities Act. Of these shares, all 76,460,616
shares will be subject to "lock-up" agreements described below on the effective
date of this offering. On the effective date of this offering, shares not
subject to the lock-up agreements described below will not be eligible for sale
pursuant to Rule 144(k). All of the directors and officers as well as
stockholders collectively holding more than 100% of the outstanding common stock
have entered into lock-up agreements with the underwriters that provide that the
shares set forth in the table below will become eligible for sale on the dates
set forth in the table below, subject in most cases to the limitations of Rule
144. In addition, holders of stock options could exercise such options and sell
certain of the shares issued upon exercise as described below.

RULE 144

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


     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately 874,606 shares immediately after this offering; or


     - the average weekly trading volume of the common stock on the Nasdaq
       National Market during the four calendar weeks preceding the filing of a
       notice on Form 144 with respect to such sale.

     Sales under Rule 144 are also subject to certain other requirements
regarding the manner of sale, notice filing and the availability of current
public information about us.

RULE 144(k)

     Under Rule 144(k), a person who is not deemed to have been one of our
"affiliates" at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an "affiliate", is
entitled to sell such shares without complying with the manner of sale, notice
filing, volume limitation or notice provisions of Rule 144. Therefore, unless
otherwise restricted, "144(k) shares" may be sold immediately upon the
completion of this offering.

RULE 701

     In general, under Rule 701, any of our employees, directors, officers,
consultants or advisors who purchases shares from us in connection with a
compensatory stock or option plan or other written agreement before the
effective date of this offering is entitled to resell such shares 90 days after
the effective date of this offering in reliance on Rule 144, without having to
comply with certain restrictions, including the holding period, contained in
Rule 144.

     The SEC has indicated that Rule 701 will apply to typical stock options
granted by an issuer before it becomes subject to the reporting requirements of
the Securities Exchange Act of 1934, along with the shares acquired upon
exercise of such options (including exercises after the date of this
prospectus). Securities issued in reliance on Rule 701 are restricted securities
and, subject to the contractual restrictions described above, beginning 90 days
after the date of this prospectus, may be sold by persons other than
"affiliates", as defined in Rule 144, subject only to the manner of sale
provisions of Rule 144 and by "affiliates" under Rule 144 without compliance
with its one year minimum holding period requirement.

                                  UNDERWRITING

     Universal Access and the underwriters for the offering (the "Underwriters")
named below have entered into an underwriting agreement with respect to the
shares being offered. Subject to certain conditions, each Underwriter has
severally agreed to purchase the number of shares indicated in the following
table. Goldman, Sachs & Co., Chase Securities Inc. and FleetBoston Robertson
Stephens Inc. are the representatives of the Underwriters.

</TABLE>

     If the Underwriters sell more shares than the total number set forth in the
table above, the Underwriters have an option to buy up to an additional
1,650,000 shares from us to cover such sales. They may exercise that option for
30 days. If any shares are purchased pursuant to this option, the Underwriters
will severally purchase shares in approximately the same proportion as set forth
in the table above.

     The following tables show the per share and total underwriting discounts
and commissions to be paid to the Underwriters by us. Such amounts are shown
assuming both no exercise and full exercise of the Underwriters' option to
purchase 1,650,000 additional shares.

     Shares sold by the Underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus. Any
shares sold by the Underwriters to securities dealers may be sold at a discount
of up to $     per share from the initial public offering price. Any such
securities dealers may resell any shares purchased from the Underwriters to
certain other brokers or dealers at a discount of up to $     per share from the
initial public offering price. If all the shares are not sold at the initial
offering price, the representatives may change the offering price and the other
selling terms.

     Universal Access, its directors, officers, employees, and certain
stockholders have agreed with the Underwriters not to sell, contract to sell,
pledge, grant an option to purchase, make a short sale or otherwise dispose of
any of our common stock or securities convertible into or exchangeable for
shares of our common stock during the period from the date of this prospectus
continuing through the

                                       75
<PAGE>   78

lock-up period, except with the prior written consent of Goldman, Sachs & Co. At
any time beginning on the third business day following the public release of our
earnings for the full fiscal quarter next following the fiscal quarter in which
the date of this prospectus falls, each stockholder may sell, contract to sell,
pledge, grant an option to purchase, make a short sale or otherwise dispose of
up to 10% of his or her shares owned as of the date of this prospectus. Each
stockholder may sell, contract to sell, pledge, grant an option to purchase,
make a short sale or otherwise dispose of his or her remaining shares at any
time on or following the date which is 180 days after the date of this
prospectus. This agreement does not apply to any existing employee benefit
plans. See "Shares Available for Future Sale" for a discussion of certain
transfer restrictions.

     At the request of Universal Access, the Underwriters have reserved at the
initial public offering price up to 2,300,000 shares of common stock for sale to
an existing stockholder of Universal Access. This stockholder expressed an
interest in purchasing such shares of common stock in this offering. This
stockholder has agreed that, if it does purchase any of such reserved shares,
the reserved shares will be subject to the lock-up described in the immediately
preceding paragraph. There can be no assurance that any of the reserved shares
will be purchased. The number of shares available for sale to the general public
in this offering will be reduced by the number of reserved shares sold. Any
reserved shares not so purchased will be offered to the general public on the
same basis as the other shares offered in this offering.

     In addition, at our request, the Underwriters have reserved up to 3.5
percent of the shares of common stock to be issued by Universal Access and
offered in this offering for sale, at the initial public offering price, to
persons with relationships with Universal Access. The number of shares available
for sale to the general public will be reduced to the extent that such persons
purchase such reserved shares. Any reserved shares which are not so purchased
will be offered by the Underwriters to the general public on the same basis as
the other shares of common stock offered by this prospectus.

     Universal Access has applied for quotation of the common stock on the
Nasdaq National Market under the symbol "UAXS".

     Prior to the offering, there has been no public market for the shares. The
initial public offering price will be negotiated among Universal Access and the
representatives. Among the factors to be considered in determining the initial
public offering price of the shares, in addition to prevailing market
conditions, will be our historical performance, estimates of our business
potential and earnings prospects, an assessment of our management and the
consideration of the above factors in relation to market valuation of companies
in related businesses.

     In connection with the offering, the Underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the Underwriters of a greater
number of shares than they are required to purchase in the offering. Stabilizing
transactions consist of certain bids or purchases made for the purpose of
preventing or retarding a decline in the market price of the common stock while
the offering is in progress.

     The Underwriters also may impose a penalty bid. This occurs when a
particular Underwriter repays to the Underwriters a portion of the underwriting
discount received by it because the representatives have repurchased shares sold
by or for the account of such Underwriter in stabilizing or short covering
transactions.

     These activities by the Underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the open
market. If these activities are commenced, they may be discontinued by the
Underwriters at any time. These transactions may be effected on the Nasdaq
National Market, in the over-the-counter market or otherwise.

                                       76
<PAGE>   79

     A prospectus in electronic format may be made available on the web sites
maintained by one or more underwriters. The underwriters may agree to allocate a
number of shares to underwriters for sale to their online brokerage account
holders. Internet distributions will be allocated by the lead managers to
underwriters that may make Internet distributions on the same basis as other
allocations.

     The Underwriters do not expect sales to discretionary accounts to exceed
five percent of the total number of shares offered.

     Universal Access estimates that the total expenses of the offering,
excluding underwriting discounts and commissions, will be approximately
$1,500,000.

     Universal Access has agreed to indemnify the several Underwriters against
certain liabilities, including liabilities under the Securities Act of 1933.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of Universal Access, Inc.

     In our opinion, the accompanying balance sheet and the related statements
of operations, of cash flows and of changes in stockholders' (deficit) equity
present fairly, in all material respects, the financial position of Universal
Access, Inc. at December 31, 1998 and 1999, and the results of its operations
and its cash flows for the period from October 2, 1997 (date of inception)
through December 31, 1997 and the years ended December 31, 1998 and 1999, in
conformity with accounting principles generally accepted in the United States.
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
auditing standards generally accepted in the United States, which require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE COMPANY

     Universal Access, Inc. (the "Company" or "UAI"), was organized and
commenced operations on October 2, 1997 for the purpose of facilitating the
provisioning, installation and servicing of dedicated communications circuits
for service providers who buy network capacity and transport suppliers who sell
network capacity. UAI provides dedicated circuit access and leases space in the
Company's Universal Transport Exchanges, or UTXs, where transport suppliers can
access the network connections of other transport suppliers. UAI operated as a
subchapter S-Corporation until September 27, 1998, at which time it converted to
a C-Corporation.

UNAUDITED PRO FORMA BALANCE SHEET

     Upon the closing of UAI's initial public offering, all of the shares of
preferred stock outstanding as of December 31, 1999 will automatically convert
into 42,834,243 shares of common stock and all preferred stock warrants
outstanding as of December 31, 1999 will automatically convert into warrants to
purchase an aggregate of 1,583,400 shares of common stock. These conversions
have been reflected in the unaudited pro forma balance sheet as of December 31,
1999. These conversions contemplate a 3-to-1 conversion ratio for Series E
Cumulative Convertible Preferred Stock and Series E Cumulative Convertible
Preferred Stock Warrants. This conversion ratio is subject to increase as
described in Note 12.

NET LOSS PER SHARE

     Basic net loss per share is computed using the weighted average number of
shares of common stock outstanding. Diluted loss per share does not differ from
basic loss per share since potential common shares from conversion of preferred
stock, stock options and warrants are anti-dilutive for all periods presented.
Pro forma basic and diluted net loss per share have been calculated assuming the
conversion of all shares of preferred stock outstanding during each period
presented into common shares, as if the shares had converted immediately upon
their issuance.

REVENUE RECOGNITION

     The following is UAI's revenue recognition policy for each type of revenue:

     Circuit access -- This is revenue earned by providing customers with
dedicated circuit access. Customers subscribe to circuit access services under
contracts ranging from twelve to sixty months. Circuit access is billed in
advance on a monthly basis. UAI recognizes revenue for circuit access as the
service is provided, and advanced billings are recorded as unearned revenue.

     Universal Transport Exchange (UTX) -- This is revenue earned by leasing
space in UAI facilities to network service providers and transport suppliers so
that they can place network equipment that may be connected to other network
service providers and transport suppliers in the UTX facility. UTX revenue is
billed in advance on a monthly basis. UAI recognizes UTX revenue on a
straight-line basis over the duration of the UTX lease, and advanced billings
are recorded as unearned revenue.

     Installation revenue -- This is revenue earned by installing a customer
circuit or installing customer UTX equipment. Through December 31, 1999, no
installation revenue has been recognized. Material installation revenue will be
recognized proportionately over the term of the related circuit access
agreement.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include cash on hand, money market funds and all
investments with an initial maturity of three months or less. All cash
equivalents are recorded at cost.

ACCOUNTS RECEIVABLE

     The allowance for doubtful accounts was $4,000, $46,000 and $649,000 at
December 31, 1997 and 1998 and 1999, respectively.

     Financial instruments that could potentially subject UAI to concentration
of credit risk primarily include accounts receivable. As of December 31, 1999,
two customers represented 55% of accounts receivable. During 1999, one customer
represented 38% of total revenues. As of December 31, 1998, two customers
represented 38% of total accounts receivable and an aggregate of 29% of total
revenues during 1998. As of December 31, 1997, three customers represented 94%
of total accounts receivable and 81% of total revenues during 1997. If any of
these individually significant customers are unable to meet their financial
obligations, results of operations of the Company could be adversely affected.

STOCK-BASED COMPENSATION

     The Company accounts for stock-based awards to employees using the
intrinsic value method as prescribed by Accounting Principles Board ("APB")
Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. Accordingly, no compensation expense is recorded for options
issued to employees or directors in fixed amounts and with fixed exercise prices
at least equal to the fair market value of the Company's common stock at the
date of grant. The Company has adopted the provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation," through disclosure only (Note 10).
All stock-based awards to non-employees are accounted for at their fair value in
accordance with SFAS No. 123.

COMPREHENSIVE INCOME

     SFAS No. 130 requires that a full set of general purpose financial
statements include the reporting of "comprehensive income." Comprehensive income
is comprised of two components: net income and other comprehensive income, with
other comprehensive income being comprised of foreign currency items, minimum
pension liability adjustments and unrealized gains and losses on certain
investments in debt and equity securities. During the periods ended December 31,
1997, 1998 and 1999, comprehensive income was comprised solely of net income. As
a result, the adoption of SFAS No. 130 had no impact on the Company's financial
statements.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost with depreciation and
amortization provided for using the straight-line method. Leasehold improvements
are amortized over the life of the lease. Depreciable lives used by the Company
for its classes of assets are as follows:

<TABLE>
<S>                                                           <C>
Furniture and fixtures......................................  3 years
UTX equipment...............................................  7 years
Computer hardware and other equipment.......................  3 years
</TABLE>

     Repairs and maintenance, which do not significantly increase the life of
the related assets, are expensed as incurred.

                             UNIVERSAL ACCESS, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

SOFTWARE CAPITALIZATION

     UAI purchases software and performs certain modification and development
activities on this software. All purchased and developed software is intended
for internal use, and accordingly, UAI accounts for these costs in accordance
with the provisions of SOP 98-1. Software costs are amortized on a straight-line
basis over a period of three years.

INTANGIBLE ASSETS

     The excess of purchase price over net assets of acquired businesses is
allocated among the identifiable intangible assets purchased and goodwill.
Intangible assets are amortized on a straight-line basis over their estimated
useful lives, generally five years.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.

IMPAIRMENT OF LONG-LIVED ASSETS

     The Company reviews its long-lived assets, including property, equipment
and intangibles, whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. The Company estimates the future cash
flows expected to result from the asset, and if the sum of the expected
undiscounted future cash flows is less than the carrying amount of the long-
lived asset, the Company recognizes an impairment loss by reducing the
depreciated cost of the long-lived asset to its estimated fair value. To date,
the Company has not recognized impairment losses on any long-lived assets.

INCOME TAXES

     On September 27, 1998, UAI changed status from an S-Corporation to a
C-Corporation. As of this date, the Company established a deferred tax asset
which reflects the tax consequences in future years of differences between the
tax basis of assets and liabilities and their financial reporting amounts. The
deferred tax asset was recorded net of a valuation allowance to reduce the
deferred tax asset to an amount that is more likely than not to be realized.

     Prior to September 27, 1998, all attributes for federal income taxes passed
through to the stockholders. Accordingly, no income tax provision or deferred
tax amounts were recorded prior to this date. Had the Company been a
C-Corporation from October 2, 1997 (inception) to September 27, 1998, no income
taxes would have been due since the Company incurred losses during this time
period.

NOTE 2 -- STOCK SPLITS AND DIVIDEND

     The Company effected a 500-for-1 common stock split in July 1998, a 2-for-1
common stock split in February 1999, a 3-for-2 common stock split in June 1999
and declared a 1-for-1 stock dividend in September 1999. All share and per share
amounts have been retroactively restated to reflect such splits and the
dividend.

NOTE 3 -- ACQUISITIONS

     On July 30, 1999, UAI acquired substantially all of the assets and
liabilities of Pacific Crest Networks, Inc ("PCN") in exchange for $833,000 in
cash, $224,000 in the assumption of debt, and 82,353 shares of Series D
Preferred Stock with a fair market value of $4.25 per share. Assets purchased
included all property and equipment, cash accounts, receivables, software,
customer lists and intellectual property. Also, as part of purchase, UAI assumed
certain liabilities of PCN including $276,000 of accounts payable, $418,000 of
obligations under capital leases, and obligations under operating leases and
vendor contracts. This acquisition was accounted for under the purchase method
of accounting. UAI assigned $1,245,000 to identifiable intangible assets and
goodwill and is amortizing this amount on a straight-line basis over a period of
five years, which represents the estimated useful lives of these intangible
assets.

     On November 1, 1999, UAI acquired substantially all of the assets of Stuff
Software, Inc. ("SSI") in exchange for $930,000 in cash and 50,021 shares of UAI
common stock with an estimated fair market value of $6.10 per share. Assets
purchased include accounts receivable, customer lists, software and intellectual
property. This acquisition was accounted for under the purchase method of
accounting. UAI assigned $1,320,000 to identifiable intangible assets and is
amortizing this amount on a straight-line basis over a period of five years. SSI
developed software and databases for the telecommunications industry. UAI will
use the assets acquired from SSI to further enhance the development of Universal
Information Exchange services.

     The following unaudited pro forma information presents the results of
operations as if the PCN and SSI acquisitions had occurred at the beginning the
periods shown after taking into account the effect of certain adjustments and
eliminations. This summary is not necessarily indicative of what the results of
operations of UAI, PCN and SSI would have been if they were a single entity
during such periods, nor does it purport to represent results of operations for
any future periods (in thousands, except per share data).

</TABLE>

     In December 1999, the Company entered into three separate term loans in the
aggregate amount of $3,300,000. Equal monthly principal and interest payments
are due commencing on December 15, 1999 and continuing through November 15,
2002. Principal amounts due under this term loan are as follows:
2000 -- $942,000, 2001 -- $1,092,000, 2002 -- $1,154,000. These notes are
collaterized by certain UAI equipment and also require UAI to maintain an
unrestricted cash balance of at least $15 million.

     In November 1997 and March 1998, the Company entered into separate note
payable agreements with two of its shareholders in the original principal
amounts of $76,000 and $50,000, respectively. The notes payable bear interest at
rates of 8.25% and 12%, respectively, and are due upon demand. The note with the
original principal amount of $76,000 is collateralized by a $63,000 security
deposit. The $50,000 note payable is unsecured. These notes were repaid in full
during 1999.

     In November 1998, the Company entered into a 36-month term loan agreement
with a bank, in the original principal amount of $149,000, for the purchase of
office furniture and equipment. The note payable is collateralized by the
Company's property and equipment, cash deposits and money market accounts with
the Bank. This note was repaid in full during 1999.

     In connection with the July 30, 1999 purchase of PCN, UAI assumed the
following debt: $150,000 note payable with a bank, $20,000 note payable to an
individual and a $54,000 note payable to the City of Eugene, OR. The $150,000
note payable to the bank was paid in full prior to December 31, 1999. The other
notes remain outstanding at December 31, 1999. The $20,000 note payable bears
interest at a rate of 10% payable monthly. The entire principal is due on
December 17, 2000. The note can be prepaid by the Company at any time without
penalty. The $54,000 City of Eugene, OR note payable bears interest at 7%. The
entire balance was due on August 1, 1999. This balance was paid in full in
February 2000.

     The Company executed unsecured promissory notes with a shareholder dated
December 29, 1998, in the original aggregate principal amount of $100,000. The
notes bear interest at a rate of 10% per year and are due upon demand, after
March 31, 1999. The Company did not receive the proceeds of these promissory
notes until after December 31, 1998; as such the notes payable were offset by
the proceeds receivable at that date for presentation purposes.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     At December 31, 1999, the Company has two line of credit arrangements to
borrow up to a total of $10,000,000. The line of credit arrangements permit
borrowings of $6,000,000 and $4,000,000 and expire in August of 2000 and April
of 2000, respectively. The available line of credit is reduced by the amount of
outstanding letters of credit. As of December 31, 1999, UAI has outstanding
letters of credit of $3,804,000, resulting in a total available line of credit
of $6,196,000. The $4,000,000 line of credit requires UAI to maintain a cash
balance in a custodial account at an amount not less than the total borrowings
and letters of credit outstanding.

NOTE 6 -- INCOME TAXES

     There is no current provision or benefit for income taxes recorded for the
period from September 27, 1998, the date of C-Corporation conversion, to
December 31, 1999, as the Company has generated net operating losses for income
taxes purposes for which there is no carryback potential. There is no deferred
provision or benefit for income taxes recorded as the Company is in a net
deferred tax asset position for which a full valuation allowance has been
recorded due to uncertainty of realization.

     The components of the deferred income tax asset are as follows (in
thousands):

     At December 31, 1999, the Company had federal and state net operating loss
carryforwards of $10,091,000. These federal and state net operating loss
carryforwards expire at various dates beginning in 2018. Due to the uncertainty
that UAI will generate future earnings sufficient to realize the benefit of
these net operating loss carryforwards, a valuation allowance for the full
amount of the deferred tax asset has been recorded. Additionally, Section 382 of
the Internal Revenue Code imposes annual limitations on the use of net operating
loss carryforwards if there is a change in ownership, as defined, within any
three-year period. The utilization of certain net operating loss carryforwards
may be limited due to the Company's capital stock transactions.

     In addition to the leases, the Company has entered into leased line
agreements with telecommunications vendors for high-capacity bandwidth. These
leases are cancelable at any time with a maximum 30-day notice. The Company, in
turn, contracts with customers for the use of the leased high-capacity
bandwidth. The customer contracts generally provide for cancellation penalties
equal to the sum of all payments due through the remainder of the contract, less
6%.

     UAI has standby letters of credit which have been issued on its behalf
totaling $3,804,000 securing performance of certain contracts with carriers and
landlords. These letters of credit expire in April 2000 and August 2000, in the
amounts of $1,656,000 and $2,148,000, respectively.


     In February 2000 a complaint was filed in the Superior Court of California,
County of Santa Clara, against UAI and other parties by Point West Ventures,
L.P., previously known as Fourteen Hill Capital,

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

L.P. and certain other shareholders in Vaultline Incorporated. The claim arises
out of a letter of intent that UAI entered into in December 1998 relating to
UAI's potential acquisition of Vaultline. The letter stated that it was not
binding on the parties except with respect to a $250,000 advance to be made by
UAI and certain obligations of Vaultline. The letter contemplated that UAI would
undertake a due diligence investigation of Vaultline. After performing the due
diligence, UAI determined not to complete the transaction and entered into a
mutual settlement agreement and release. Subsequently, Vaultline ceased doing
business. The claimants contend that the mutual settlement agreement executed by
the president of Vaultline was unauthorized. They allege that UAI, certain of
UAI's officers and others conspired to deprive them of their interests in
Vaultline. They are seeking damages in excess of $10,000,000. UAI believes all
legal obligations were satisfied and intends to vigorously contest any claims
relating to this matter. Accordingly, no amount has been accrued as a liability
as of December 31, 1998 and 1999.

     The Company is involved in various other legal matters in the ordinary
course of business. In the opinion of management, the ultimate resolution of
these matters will not have a material adverse impact on the Company's financial
position, results of operations or cash flows.

NOTE 8 -- RELATED PARTY TRANSACTIONS

     During 1998, UAI entered into certain transactions with shareholders and
directors for the lease of office space and pager equipment. Rent expense for
these leases approximated $65,000 in 1998. There was no related party rent
expense incurred in 1999.

     During 1998 and 1999, UAI paid Broadmark Capital Corporation ("Broadmark"),
an entity for which a member of the UAI Board of Directors serves as Chairman,
certain consideration in exchange for services rendered related to the sale of
preferred stock. During 1999, UAI paid cash amounts of $162,000, $200,000 and
$140,000 to Broadmark in connection with the sale of Series A, B and D
Cumulative Convertible Preferred Stock, respectively. These amounts were
recorded as issuance costs, and deducted from the gross proceeds of the
respective preferred stock series. During 1999, UAI issued to Broadmark 360,000
common stock warrants with an exercise price of $.50 in connection with services
rendered related to the issuance of Series B Cumulative Convertible Preferred
Stock ("Series B Preferred Stock"). UAI also issued to Broadmark 77,233 Series A
Cumulative Convertible Preferred Stock Warrants ("Series A Warrants") in
connection with services rendered related to the issuance of Series A Cumulative
Convertible Preferred Stock. UAI issued 33,333 and 43,900 of these Series A
Warrants in 1998 and 1999, respectively. The common stock warrants and the
Series A Warrants were valued at $13,000 and $83,000, respectively, using the
Black-Scholes valuation model. UAI issued $36,000 of the Series A Warrants in
1998 and $47,000 of the Series A Warrants in 1999. Also, in connection with
services rendered related to the sale of Series B Preferred Stock, UAI caused
options to purchase 840,000 shares of common stock at $.50 per share to be
granted by certain principal shareholders of the Company's common stock. The
840,000 common stock options granted by the principal shareholders were valued
at $31,000 using the Black-Scholes valuation model. This amount was recorded as
paid-in capital.

     On May 27, 1999, UAI executed a full-recourse promissory note in connection
with a loan to an officer of the Company for a principal amount of $200,000 with
a per annum interest rate of 6%. The promissory note will become immediately due
and payable on April 30, 2004.

     On August 4, 1999, three of the Company's officers were granted options to
purchase a total of 1,000,000 shares of common stock at exercise prices ranging
from $1.38 to $1.51 per share. These exercise prices were at or above the fair
market value of the common stock on August 4, 1999. These stock options vested
immediately and were exercised on the date of grant. In connection with the
exercise, the UAI board of directors authorized loans to these officers,
pursuant to non-recourse

promissory notes for a total amount of $1,485,000 with an annual interest rate
of 6%. The promissory notes will become immediately due and payable on August 4,
2004. The issuance of these notes receivable to effect the exercise of these
stock options caused variable plan accounting to apply to the underlying stock
options. Accordingly, during 1999, UAI recorded $4,611,000 of stock option plan
compensation expense related to these notes. The terms of these notes receivable
were amended on December 6, 1999 such that no future stock option plan
compensation expense will be recognized related to the stock options underlying
these notes.

NOTE 9 -- INDUSTRY SEGMENT AND GEOGRAPHIC INFORMATION

     The company is currently operating under one segment, the provisioning of
network access.

     From its inception through December 31, 1999, substantially all of the
Company's identifiable assets were located in the United States. During that
same period, substantially all of the Company's revenues were derived from sales
to customers based in the United States. The Company currently operates under
one operating segment. Operating activities of this segment primarily consist of
the provision of dedicated circuit access and related Universal Transport
Exchange and Universal Information Exchange services.

NOTE 10 -- EMPLOYEE BENEFIT PLANS AND EMPLOYMENT AGREEMENTS

EMPLOYEE SAVINGS AND BENEFIT PLANS

     As of January 1, 1999, UAI implemented a retirement savings plan pursuant
to Section 401(k) of the Internal Revenue Code, which covers substantially all
of the Company's employees. Employer contributions to the retirement savings
plan are discretionary. During 1999, $58,000 of employer contributions were
recorded as an expense.

EMPLOYMENT AGREEMENTS

     UAI has entered into employment agreements with several of its key
employees which have initial terms ranging from one to three years, after which
they are renewable for additional one-year periods. The employment agreements
entitle the employee to receive certain severance payments for termination of
employment without cause, as defined by the agreements. These employment
agreements will require UAI to pay these key employees approximately $1.1
million in salary from December 31, 1999 through the end of the respective
agreements. The agreements also provide for the payment of both discretionary
and performance based bonuses.

STOCK OPTION PLANS

     In July of 1998, UAI's Board of Directors adopted the 1998 Employee Stock
Option Plan (the "1998 Plan") for the Company's directors, officers, employees
and key advisors. The total number of shares of UAI common stock reserved for
issuance under the Plan is 13,000,000. Awards granted under the plan are at the
discretion of the Company's Board of Directors, or a compensation committee
appointed by the Board of Directors, and may be in the form of either incentive
or nonqualified stock options. At December 31, 1999, 934,250 shares of common
stock were available for additional awards under the plan.

     In November 1999, UAI's Board of Directors adopted the 1999 Stock Plan and
the 1999 Director Option Plan. The 1999 Director Option Plan will be effective
on the effective date of a qualified initial public offering. Upon a qualified
initial public offering, no further options will be granted under the 1998 Plan.
The 1999 Stock Plan provides for the grant of incentive stock options to
employees, and the grant of nonstatutory stock options and stock purchase rights
to employees, directors and

consultants. As of December 31, 1999, 10,000,000 shares of common stock were
reserved for issuance pursuant to the 1999 Stock Plan. The 1999 Director Option
Plan provides for the issuance of options to purchase 20,000 shares of common
stock to each non-employee director upon the later of (i) the effective date of
the 1999 Director Option Plan or (ii) when such person first becomes a non-
employee director, and provides for the issuance of options to purchase 5,000
shares of common stock to each non-employee director on June 30 of each year,
subject to certain limitations. As of December 31, 1999, 500,000 shares of
common stock were reserved for issuance pursuant to the 1999 Director Option
Plan.

     If the Company had elected to recognize compensation cost based on the fair
value of the options as prescribed by Statement of Financial Accounting Standard
No. 123, "Accounting for Stock-Based Compensation", the following results would
have occurred using the Black-Scholes option-pricing model with the listed

     The Company recognized $689,000 and $8,146,000 of option plan compensation
expense during 1998 and 1999, respectively, and expects to recognize additional
expense of approximately $11,909,000 over the next four years relating to such
options as they vest. The $8,146,000 of option plan compensation expense for
1999 consisted of $3,535,000 related to the amortization of deferred stock
option plan compensation and $4,611,000 related to the options exercised in
exchange for notes receivable as described in Note 8.

     The vesting term of options granted under the Plan shall be fixed by the
Board of Directors, or compensation committee elected by the Board of Directors,
but in no case shall be exercisable for more than 10 years after the date the
option is granted. For option grants to persons owning 10% of the voting power
of all outstanding classes of UAI capital stock, the exercise price may not be
lower than 110% of the fair market value on the date of the grant and the option
term may not exceed 5 years.

     During 1998, 600,000 stock options were issued to non-employees for
services rendered during 1998. These options were issued with an exercise price
of $0.01, were immediately exercisable, and comprised $300,000 of the $689,000
stock option plan compensation expense recognized during 1998. During 1998, all
options issued to non-employees were exercised.

     The above disclosures include 200,000 options granted on August 4, 1999 to
a non-employee director, for which $764,000 of compensation expense was
recognized during 1999.

NOTE 11 -- NET LOSS PER SHARE

     The Company had securities outstanding which could potentially dilute basic
earnings per share in the future, but were excluded in the computation of
diluted net loss per share in the periods presented, as their effect would have
been anti-dilutive. Such outstanding securities are convertible into the number
of shares of common stock as set forth in the table below at December 31, 1998
and 1999. There were no potentially dilutive securities outstanding from
inception through December 31, 1997.

NOTE 12 -- CONVERTIBLE PREFERRED STOCK AND WARRANTS

     During 1998, UAI issued 335,334 shares of Series A Redeemable Cumulative
Convertible Preferred Stock ("Series A Preferred Stock") for gross proceeds of
$1,006,000. Additionally, UAI received cash and accepted subscription documents
for 385,830 shares of Series A Redeemable Cumulative Convertible Preferred Stock
("Unissued Series A Preferred Stock") for gross proceeds of $1,157,000. This
amount, net of issuance costs of $153,000, was recorded as a liability as of
December 31, 1998. As of December 31, 1998, the Company had authorized 1,000,000
shares of Series A Preferred Stock. On February 8, 1999, UAI issued 436,997
shares of Series A Preferred Stock for gross proceeds of $1,311,000. Included in
this issuance were the 385,830 shares related to the amount presented as
Unissued Series A Preferred Stock at December 31, 1998.

     In connection with the 1998 sale of Series A Preferred Stock, UAI issued
warrants (the "Series A Warrants") to purchase an additional 33,333 shares of
Series A Preferred Stock at $3.00 per share. These warrants were valued at
$36,000 using the Black-Scholes valuation model. In connection with the February
1999 sale of Series A Preferred Stock UAI issued warrants to purchase 43,900
shares of Series A Preferred Stock at $3.00 per share. These warrants were
valued at $47,000 using the Black-

Scholes option valuation model. The Series A Warrants are exercisable for a
period of five years after the issuance date. The Series A Preferred Stock is
shown net of the fair value of the Series A Warrants.

     As of December 31, 1998, the holders of Series A Preferred Stock had the
right to demand the Company to redeem one-third of the shares originally
purchased on each of the fourth, fifth, and sixth anniversaries of the closing
and UAI had the right to redeem not less than all of the outstanding Series A
Preferred Stock between the third and sixth anniversaries of the closing. All
redemptions were to be made at amount equal to the sum of the original purchase
price of the Series A Preferred Stock plus accumulated but unpaid dividends. On
February 3, 1999, the Series A Preferred Stock holders approved an amended
Certificate of Designations, Rights and Preferences whereby this mandatory
redemption feature was terminated. Accordingly, the entire balance of the
redeemable cumulative convertible preferred stock and redeemable cumulative
convertible preferred stock warrants was reclassified to stockholders' equity on
February 3, 1999.

cumulative convertible preferred stock warrants are as follows (in thousands,

     On February 8, 1999, UAI issued 2,000,000 shares of Series B Redeemable
Cumulative Convertible Preferred Stock ("Series B Preferred Stock") for gross
proceeds of $6,000,000. In conjunction with the issuance of the Series B
Preferred Stock, the Company issued warrants to purchase an additional 400,002
shares of Series B Preferred Stock (the "Series B Warrants") at an exercise
price of $0.01 per share and warrants to purchase 360,000 shares of Common Stock
at $.50 per share, and caused options to purchase 840,000 shares of Common Stock
at $.50 per share to be granted by certain principal shareholders of the
Company's Common Stock. The 840,000 common stock options granted by the
principal shareholders were valued at $31,000 using the Black-Scholes valuation
model. This amount was recorded as additional paid-in capital. Series B
Preferred Stock is convertible into Common Stock on a 6-for-1 basis. During the
six month period ended June 30, 1999, 233,335 of the Series B Warrants were
exercised.

     On May 13, 1999, UAI issued 666,667 shares of Series C Convertible
Preferred Stock ("Series C Preferred Stock") for gross proceeds of $2,000,001.

     During the period from June 30, 1999 to September 30, 1999, UAI issued
5,957,611 shares of Series D Cumulative Convertible Preferred Stock ("Series D
Preferred Stock") for gross proceeds of $25,319,847. The Company also issued
82,353 shares valued at $4.25 per share in connection with the purchase of
certain assets of PCN (see Note 3). The Company also issued 2,733 shares of
Series D Preferred Stock on December 6, 1999 for gross proceeds of $50,014.

     On November 10, 1999, UAI issued 1,557,385 shares of Series E Cumulative
Convertible Preferred Stock ("Series E Preferred Stock") and warrants to
purchase an additional 40,000 shares of Series E Preferred Stock for gross
proceeds of $28.5 million. The Company ascribed $136,000 of the proceeds to the
warrants using the Black-Scholes option valuation model. Series E Preferred
Stock is convertible into Common stock on a 3-for-1 basis. The conversion ratio
for the Series E Preferred Stock will be multiplied by the quotient of $750
million divided by the product of the number of fully diluted shares of common
stock outstanding immediately before an initial public offering multiplied by
the initial public offering per share price (such quotient is not to be less
than 1). The conversion ratio cannot exceed 3.75-for-1. The Company's initial
public offering (IPO) document estimates that the IPO price per share will be
between $8.00 and $10.00. If the IPO is ultimately priced at $8.00 per share,
the Company will record a "deemed dividend" at that time in the amount of
$2,135,000. The amount of the deemed dividend will decrease as the IPO price
increases above $8.00 per share and will be zero at an IPO price of $8.60 per
share. The Series E Preferred Stock warrants have an exercise price of $18.30
per share.

     A portion of the Series D Preferred Stock was issued at a price that was
below the deemed fair market value of the equivalent amount of common stock.
Accordingly, the Company recorded a deemed dividend of $9.0 million related to
the issuance of Series D Preferred Stock. The deemed dividend has been included
in the accretion and dividends on redeemable and nonredeemable cumulative
convertible preferred stock for purposes of determining basic and diluted net
loss per common share.

     Upon liquidation or dissolution, shareholders of Preferred Stock will be
distributed available assets up to the sum of the original purchase price plus
accumulated but unpaid dividends. This distribution has preference over any
distribution to common stock holders.

     Holders of the Company's Preferred Stock are entitled to cumulative
dividends (payable in cash or stock at the Company's discretion) and have the
right to convert their shares at any time into shares of UAI Common Stock as
follows:

     A qualified initial public offering of at least $1 per share triggers a
mandatory conversion of all outstanding Preferred Stock into Common Stock, and
of all outstanding Preferred Stock Warrants into warrants to purchase Common
Stock at the above conversion ratios.

     The holders of the Preferred Stock and the holders of Common Stock vote as
one class, subject to certain provisions. Each share of Preferred Stock is
entitled to cast the number of votes equal to the number of Common Shares into
which their preferred stock is convertible.

NOTE 1 -- DESCRIPTION OF THE COMPANY

     Pacific Crest Networks, Inc. (the "Company" or "PCN"), an Oregon
Corporation, was originally organized in 1995 as Cascade Communications Group
("Cascade"), a partnership, for the purpose of providing internet access
services. In May 1996, the partners of Cascade formed a new corporation, Pacific
Crest Interactive, Inc., and assigned all of the assets and liabilities of
Cascade to the new corporation. During 1997, Pacific Crest Interactive continued
to provide internet access services; however, it also began to focus on the
development and deployment of broadband network access and introduced its core
broadband network products in 1998. In October 1998, the Company changed its
name to Pacific Crest Networks, Inc. The Company presently provides internet
access services to the general public and high-speed broadband network
technologies and data transport services primarily to internet service providers
and business customers. During 1998, all of the Company's customers were located
in the State of Oregon, and in 1999, operations were expanded to the State of
Washington.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

     The accompanying interim financial statements as of June 30, 1999 and for
the six months ended June 30, 1998 and 1999 and the related notes have not been
audited. However, they have been prepared in conformity with the accounting
principles stated in the audited financial statements for the years ended
December 31, 1997 and 1998 and include all adjustments, which were of a normal
and recurring nature, which in the opinion of management are necessary to
present fairly the financial position of the Company and results of operations
and cash flows for the periods presented. The operating results for the interim
periods are not necessarily indicative of results expected for the full years.

REVENUE RECOGNITION

     The following describes PCN's revenue recognition policy for each type of
revenue:

     Internet access (Pond) -- This revenue relates to internet access service
that PCN provides to business and residential customers. This service is billed
monthly in advance at the beginning of each calendar month. This revenue is then
recognized during the month that the service is provided.

     Digital subscriber line (DSL or SNAP) service -- This revenue relates to
the provision of digital subscriber lines to both end users and internet service
providers (ISPs). This service is billed monthly on a calendar month basis in
the month that the service is provided. Revenue is recognized each month as the
service is provided.

     DSL service to multi-unit residences (DASH) -- This revenue relates to the
provision of DSL service to multi-unit residences. This service is billed
monthly on a calendar month basis in the month that the service is provided.
Revenue is recognized each month as the service is provided.

CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include cash on hand, money market funds and all
investments with an initial maturity of three months or less. All cash
equivalents are recorded at cost.

STOCK-BASED COMPENSATION

     The Company accounts for stock-based awards to employees using the
intrinsic value method as prescribed by Accounting Principles Board ("APB")
Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. Accordingly, no compensation expense is recorded for options
issued to employees in fixed amounts and with fixed exercise prices at least
equal to the fair market value of the Company's common stock at the date of
grant. The Company has adopted the provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation," through disclosure only (Note 7). All stock-based
awards to non-employees are accounted for at their fair value in accordance with
SFAS No. 123.

COMPREHENSIVE INCOME

     SFAS No. 130 requires that a full set of general purpose financial
statements include the reporting of "comprehensive income." Comprehensive income
is comprised of two components: net income and other comprehensive income, with
other comprehensive income being comprised of foreign currency items, minimum
pension liability adjustments and unrealized gains and losses on certain
investments in debt and equity securities. During the years ended December 31,
1997 and 1998, comprehensive income was comprised solely of net income. As a
result, the adoption of SFAS No. 130 had no impact on the Company's financial
statements.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost with depreciation provided for
under the straight-line method. Leasehold improvements are amortized over the
remaining life of the lease. Depreciable lives used by the Company for its
classes of assets are as follows:

<TABLE>
<S>                                                          <C>
Furniture and fixtures.....................................  7 years
Computer hardware..........................................  5 years
Computer software..........................................  3 years
</TABLE>

     Certain property and equipment has been acquired through capital leasing
arrangements. This property and equipment is recorded at the present value of
total lease payments using the rate of interest implicit in the lease. The
recorded amount is then amortized over the lesser of the useful life of the
related asset or the term of the lease.

INCOME TAXES

     Deferred income taxes are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax basis and for tax
carryforwards. Deferred tax assets are offset by a valuation allowance to the
extent it is more likely than not that the future tax benefit of the deferred
tax asset will not be realized.

     The Company has established a net deferred tax asset which reflects the tax
consequences in future years of differences between the tax basis of assets and
liabilities and their financial reporting amounts. The deferred tax asset was
recorded net of a valuation allowance to reduce the deferred tax asset to an
amount that is more likely than not going to be realized.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.

     During 1998, the Company issued an unsecured note payable to an unrelated
individual for $20,000. The note bears interest at a rate of 10% payable
monthly. The entire principal is due on December 17, 2000. The note can be
prepaid by the Company at any time without penalty.

     During 1998, the Company obtained an unsecured line of credit of $400,000
from a shareholder. At December 31, 1998, the balance outstanding was $158,000.
The line of credit does not bear interest and all outstanding borrowings are due
on December 31, 1999 or upon the sale of the Company. An interest rate on the
borrowings was imputed at a rate of 12%, which represents management's estimate
of the Company's unsecured borrowing rate. Interest expense on this note was
$2,000 in 1998. The imputed interest is included in the balance of the note
since the Company intends to repay the shareholder the principal balance plus
all imputed interest.

     During 1997, two shareholders advanced funds to the Company. As of December
31, 1997, the balance of the outstanding borrowings was $6,000. During 1998,
$4,000 of this balance was paid in full, and the remaining $2,000 was added to
the $158,000 note payable described above. These borrowings were not subject to
any written agreement. The Company did not record imputed interest on these
borrowings since the estimated interest charges were insignificant.

     In August 1998, the Company issued a $150,000 note payable to a Bank. This
note bears interest at a rate of prime plus 3% with interest payments due
monthly. The interest rate at December 31, 1998 was 10.75%. The entire balance
of this note is due upon demand with an established final maturity of August 1,
1999. The note is collateralized by substantially all of the assets of the
Company. Further, the entire principal balance of the note and accrued interest
are personally guaranteed by the three stockholders of the Company.

     In September 1996, the Company entered into a business loan agreement with
the City of Eugene, Oregon in the amount of $100,000. The note bears interest at
7%. The Company is currently paying monthly interest and principal payments of
approximately $2,000 with a final principal payment of $51,000 due on August 1,
1999. This loan is collateralized by substantially all of the assets of the
Company. In addition, a stockholder of the Company personally guaranteed the
entire loan balance and accrued interest and also pledged certain personal real
property as collateral.

     At December 31, 1997 and 1998, the Company had a federal and state net
operating loss carryforwards of $131,000 and $518,000, respectively. The net
operating losses will expire in 2016 through 2018 for federal purposes, and 2011
through 2013 for state purposes. Upon cumulative ownership changes of more than
50% over a three year period (see Note 10), certain limitations apply to the
amount of net operating loss that can be deducted from taxable income in each
future year. The net operating loss carryforward limitation in each year in the
carryforward period approximates the product of the fair market value of the
Company immediately before ownership transfer multiplied by the long-term
federal interest rate.

NOTE 7 -- STOCK OPTIONS

     During 1997 and 1998, the Company's Board of Directors granted stock
options to two individuals who were both employees of the Company and members of
the Board of Directors. The Company does not have a formal stock option plan,
nor are there any shares specifically reserved for stock option grants. All
options issued had an exercise price of $.001, were immediately exercisable, and
expired three years after the date of grant.

     During 1997 and 1998, the Company calculated compensation cost based on the
fair value of the underlying Common Stock on the date of grant. The fair value
of the Common Stock was deemed to represent the fair value of the stock options,
since the exercise price of the stock options was de minimis.

     During 1997 and 1998, the Company recognized stock option plan compensation
expense of $20,000 and $248,000, respectively.

     The weighted average fair value of all options granted during 1997 and 1998
was $.0305 and $.0354, respectively.

     As set forth in Note 2, the Company accounts for stock based awards to
employees in accordance with APB 25. Compensation cost would remain unchanged

123.

all of the issued and outstanding preferred stock to common stock. This action

the initial issuance price of the common stock.

                         NOTES TO FINANCIAL STATEMENTS
                  INFORMATION FOR THE NINE MONTH PERIODS ENDED
                    SEPTEMBER 30, 1998 AND 1999 IS UNAUDITED

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE COMPANY

     Stuff Software, Inc. (the "Company") operates as a Florida Subchapter S
Corporation. From its inception through November 30, 1998, Stuff Software, Inc.
operated as a sole proprietorship. The November 30, 1998 reorganization is
reflected retroactively throughout the financial statements for all periods
presented. The Company develops software and databases for use in the area of
telecommunications cost and benefit analysis.

BASIS OF PRESENTATION

     The accompanying interim financial statements as of September 30, 1999 and
for the nine months ended September 30, 1998 and 1999 and the related notes have
not been audited. However, they have been prepared in conformity with the
accounting principles stated in the audited financial statements for the years
ended December 31, 1997 and 1998 and include all adjustments, which were of a
normal and recurring nature, which in the opinion of management are necessary to
present fairly the financial position of the Company and results of operations
and cash flows for the periods presented. The operating results for the interim
periods are not necessarily indicative of results expected for the full years.

REVENUE RECOGNITION

     Substantially all of the Company's revenues are derived from selling
information in a database maintained by the Company, and providing customers
with either quarterly or monthly updates of this database information. The
initial database and subsequent updates are provided to customers on CD-ROM. For
sales of the CD-ROM database that provide for periodic updates, revenue is
recognized on a straight-line basis over the term of the respective customer
contract. For sales of the CD-ROM database where the Company is not obligated to
provide any future updates or services, the entire sale amount is recognized
upon delivery of the CD-ROM database.

ACCOUNTS RECEIVABLE

     Financial instruments that could potentially subject Stuff Software to
concentration of credit risk primarily include accounts receivable. As of
December 31, 1998, three customers represented 43% of total accounts receivable
and no customer represented more than 10% of total revenues during 1998. As of
December 31, 1997, no customer represented more than 10% of total accounts
receivable and no customer represented more than 10% of total revenues during
1997. If any of these individually significant customers are unable to meet
their financial obligations, results of operations of the Company could be
adversely affected.

COMPREHENSIVE INCOME

     SFAS No. 130 requires that a full set of general purpose financial
statements include the reporting of "comprehensive income." Comprehensive income
is comprised of two components: net income and other comprehensive income, with
other comprehensive income being comprised of foreign currency items, minimum
pension liability adjustments and unrealized gains and losses on certain
investments in debt and equity securities. During the years ended December 31,
1997 and 1998, comprehensive income was comprised solely of net income. As a
result, the adoption of SFAS No. 130 had no impact on the Company's financial
statements.

                  INFORMATION FOR THE NINE MONTH PERIODS ENDED
                    SEPTEMBER 30, 1998 AND 1999 IS UNAUDITED

ADVERTISING COSTS

     The Company expenses advertising costs as incurred. For the years ended
December 31, 1997 and 1998, advertising expense totaled $5,000 and $6,000,
respectively.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.

NOTE 2 -- INCOME TAXES

     Stuff Software, Inc. changed status from a sole proprietor to a
S-Corporation on November 30, 1998. For both a sole proprietorship and a
S-Corporation, all attributes for federal and state income taxes pass through to
the stockholder. Accordingly, no income tax provision or deferred tax amounts
have been recorded.

NOTE 3 -- INDUSTRY SEGMENT AND GEOGRAPHIC INFORMATION

     During the years ended December 31, 1997 and 1998, substantially all of the
Company's identifiable assets were located in the United States. During that
same period, substantially all of the Company's revenues were derived from sales
to customers based in the United States.

                          UNAUDITED PRO FORMA COMBINED
                            STATEMENT OF OPERATIONS

     The following unaudited pro forma combined statement of operations assumes
the acquisitions of Pacific Crest Networks, Inc. d/b/a The Pond ("Pacific Crest
Networks" or "PCN") and Stuff Software, Inc. ("Stuff Software" or "SSI") by
Universal Access, Inc. ("Universal Access" or "UAI") accounted for on the
purchase method of accounting and are based on the respective historical
financial statements and the notes thereto, which are included in this
Registration Statement. No unaudited pro forma balance sheet is presented, as
all assets and liabilities of PCN and SSI are included in the audited balance
sheet of UAI as of December 31, 1999. This unaudited pro forma statement of
operations gives effect to the acquisitions as if they had occurred on January
1, 1999. The unaudited pro forma combined statement of operations for the year
ended December 31, 1999 combines UAI's audited historical results for the year
ended December 31, 1999 with the unaudited historical statements of operations
of Pacific Crest Networks and Stuff Software for the periods from January 1,
1999 to July 30, 1999 and November 1, 1999, the respective acquisition dates.

     There were no material differences between the accounting policies of UAI
and those of Pacific Crest Networks and Stuff Software.

     The unaudited pro forma information included herein is presented for
illustrative purposes only and is not necessarily indicative of the operating
results that would have occurred had the acquisitions been consummated at the
beginning of the period presented, nor is it necessarily indicative of future
operating results.

     These pro forma financial statements are based on, and should be read in
conjunction with, the historical financial statements and the related notes
thereto of Universal Access, Pacific Crest Networks and Stuff Software included
in this Registration Statement.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

     Article VIII of Universal Access' Restated Certificate of Incorporation
provides for the indemnification of directors to the fullest extent permissible
under Delaware law.

     Article VI of Universal Access' Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of Universal Access if
such person acted in good faith and in a manner reasonably believed to be in and
not opposed to the best interest of Universal Access, and, with respect to any
criminal action or proceeding, the indemnified party had no reason to believe
his or her conduct was unlawful.

     Universal Access has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for in
Universal Access' Bylaws, and intends to enter into indemnification agreements
with any new directors and executive officers in the future.

    ITEM 17. UNDERTAKINGS

     Universal Access hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification by Universal Access for liabilities arising
under the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of Universal Access pursuant to the provisions referenced in
Item 14 of this Registration Statement or otherwise, Universal Access has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act, and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by Universal Access of expenses
incurred or paid by a director, officer, or controlling person of Universal
Access in the successful defense of any action, suit or proceeding) is asserted
by a director, officer or controlling

                                      II-7
<PAGE>   134

person in connection with the securities being registered hereunder, Universal
Access will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

     Universal Access 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 Universal Access pursuant to Rule 424(b)(1)
     or (4) or 497(h) under the Securities Act shall be deemed to be part of
     this Registration Statement as of the time it was declared effective.

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

                           CARRIER SERVICES AGREEMENT
                                  (MULTIMEDIA)

                                                         AGREEMENT NO.98R0613.00


This Carrier Services Agreement (this "Agreement") is made this 29th day of
June, 1998, by and between Williams Communications, Inc. d/b/a Williams Network
Services, a Delaware corporation ("Seller"), with its principal place of
business at One Williams Center, 26th Floor, Tulsa, Oklahoma 74172 and Universal
Access, Inc., an Illinois corporation ("Customer"), with its principal place of
business at 1021 Adams Street, Suite 101, Chicago, Illinois 60607, for the
provision of multimedia telecommunications services, set forth in this
Agreement.

1.0.     SCHEDULES.

The Schedules attached to this Agreement and made a part hereof are:

Schedule A - Williams Network Services Asynchronous Transfer Mode Service
Schedule including Pricing and Specifications

Schedule B - Williams Network Services Private Line Service Schedule including
Pricing and Specifications

Schedule C - List of Seller's On-Net Cities

2.0.     DESCRIPTION OF SERVICES AND PRICING.

Customer may order from Seller multimedia transmission services ("Services"),
the terms and conditions of which and the charges for which are set forth in
Seller's currently prevailing Multimedia Transmission Service Schedule relating
to such Services (the "Service Schedule"). Current Service Schedules are
attached to this Agreement, labeled as consecutive Schedules and incorporated
herein by this reference. Seller offers such Services, as defined in the
applicable Service Schedule, upon the terms and conditions set forth in the
Service Schedule, this Agreement, and any applicable tariff (the "Tariff") filed
by Seller with the Federal Communications Commission. The terms and conditions
of this Agreement (including the Schedules) are subject to change in accordance
with and to the extent of any changes made in such Tariff, if applicable, or as
such changes are generally applicable to Seller's other customers ordering
similar services, provided, however in no event shall the cost of On-Net IXC
Services be increased from current levels for the remainder of the term of this
Agreement. All Services and "Ancillary Services," as defined in Section 5.3, are
subject to availability.

3.0      EFFECTIVE DATE AND TERM

3.1      This Agreement shall become effective on the date on which Seller signs
the Agreement ("Effective Date").

3.2       The duration of this Agreement shall continue for a term of [***]
years (the "Initial Term") from the date by which Customer must meet its Revenue
Commitment (as defined below). This Agreement shall thereafter automatically
renew for successive five-year periods (each, a "Renewal Term") unless canceled
by either party by giving written notice of such cancellation not less than
sixty (60) days before the end of the Initial Term or any Renewal Term. Unless
Customer is in Default, any Service being provided at the time of termination
shall continue until the natural end of such Service as specified in the
applicable Service Schedule upon the terms and conditions of this Agreement;
provided that Customer may not order any new Service without first renewing this

Agreement. The charges for Services and Ancillary Services during any such
extension shall be the then current Seller charges provided, however in no event
shall the cost of On-Net IXC Services be increased from current levels for the
remainder of the term of this Agreement. To the extent Seller (a) files a Tariff
incorporating a reduction in the price applicable to any Service or Ancillary
Service being provided to Customer under this Agreement or any Service Schedule,
or (b) reduces its standard list price for any Service or Ancillary Service for
such Service being provided to Customer under this Agreement or any Service
Schedule, then Seller shall reduce the prices charged to Customer
proportionately with respect to any such Service or Ancillary Service as of the
date of filing of such Tariff or reduction of such standard list price, as the
case may be (i.e. a retail price reduction of 10% would constitute a 10% price
reduction on existing rates for Customer on the services effected.)

3.3     Commencing [***] months after the calendar month including the Effective
Date, Customer shall be obligated to have signed orders for on-network Services
in the amount of [***] dollars [***] in total aggregate monthly billings (the
"Revenue Commitment"). For the first [***] months, Customer will receive the
discounted rate associated with the [***] revenue level. If, after the [***]
month, Customer reaches [***]in monthly revenues, it will receive the discounted
rate associated with the [***] revenue level. If Customer reaches [***] in
monthly revenues by month [***], it will receive the discounted rate associated
with the [***]revenue level. If Customer reaches [***] in monthly revenues by
month [***] or at the month thereafter, Customer will receive the discounted
rate associated with the [***] and over revenue level. If any of the above
revenue levels are achieved, Customer will be billed at the discounted rate
associated with the revenue level they have achieved. All charges for Services
in this Agreement shall be determined in accordance with the pricing set forth
in the Service Schedules attached hereto or on Customer's Service Orders, as
applicable, inclusive of any discounts applicable to Customer, but exclusive of
any credits to which Customer may be entitled, late payment penalties, taxes and
other government-imposed surcharges. Customer's purchases of Services shall also
not include payments made by Customer to Seller to reimburse Seller for third
party costs paid to unaffiliated entities, including, but not limited to, local
access charges, taxes, installation charges, off-network charges, one-time fees
and other similar costs. To the extent that, in any month during the Initial
Term hereof, Customer fails to have signed orders or a total aggregate billing
of applicable Services from Seller greater than or equal to the Revenue
Commitment amount, Williams shall invoice Customer on Customer's next invoice,
an amount equal to the difference between the Revenue Commitment amount and the
amount of Services actually purchased or committed to by order by Customer. For
purposes of this entire agreement, "on-network" means interexchange service
provided by Seller on facilities owned by Seller and bounded by Seller points of
presence or services that are ordered and scheduled to be Seller owned
facilities within a one year period from the date of order. (i.e. Customer will
receive On-Net pricing at the time of the order provided that the Seller has
indicated that the route will be On-Net within 12 months of the order.) At the
time that the Off-Net circuit is available for On-net use, Customer agrees to
convert circuit to On-net facilities at the first mutually acceptable date and
time.

4.0      SERVICE ORDERS.

Services requested by Customer hereunder shall be requested on Seller's Service
Order forms in effect from time to time or on Customer's forms accepted in
writing by Seller ("Service Orders"). Each Service Order shall reference this
Agreement and its respective Agreement number. Seller reserves the right not to
accept a Service Order under this Agreement at any time.

When a Service Order is placed, the Customer will indicate a requested start
date (A Requested Start Date). Seller will make reasonable efforts to meet the
Requested Start Date. In the event that a Requested Start Date is altered, the
actual Start Date will be changed to reflect the number of days of delay or
advance, as appropriate.

This Agreement shall apply to all Services and Ancillary Services provided by
Seller to the Customer whether

                                  Page 2 of 24

pursuant to a Service Order or otherwise.

Any conflicting, different or additional terms and conditions contained in
Customer's acknowledgment or Service Order or elsewhere are objected to by
Seller and shall not constitute part of this Agreement. No action by Seller
(including, without limitation, provision of Services or Ancillary Services to
Customer pursuant to such Service Order) shall be construed as binding or
estopping Seller with respect to such term or condition, unless the Service
Order containing said specific term or condition has been signed by an
authorized headquarters representative of Seller.

Seller shall make reasonable efforts to provide Services within its standard
service implementation interval or on Customer's requested Start Date. Services
shall begin on the date Seller issues notice that service is available (the
"Start of Service Notice or (SOSN), indicating the service has been tested by
Seller in accordance with Seller's standard specifications and that the service
meets or exceeds those specifications.


Customer may request a delay in the Start Date of an order, a move, or
rearrangement when Seller receives delay request a minimum of fifteen (15) days
prior to the due date and the requested delay does not extend beyond (30)
cumulative days from the Service Orders initial Start Date. When Customer has
delayed a Service Order for the maximum thirty (30) cumulative calendar days,
the order may not be delayed again by Customer. Once the maximum thirty (30)
day delay has been achieved, Customer has the option to (a) accept the billing
for the Service Order, or (b) cancel the Service Order and pay the applicable
cancellation charges for the facilities ordered. The billing or cancellation is
effective on the 30th cumulative calendar of the delay. If Customer elects to
accept billing, the installation will be completed as soon as reasonably
practical after Customer advises Seller that the installation can be completed.



5.0.     LOCAL ACCESS AND ANCILLARY SERVICES.



5.1.     Seller shall, on behalf and upon request of Customer, obtain
telecommunications facilities connecting Customer, with an approved vendor of
Seller, to a Seller Point of Presence (POP). Customer will execute a Letter of
Agency, on such form as provided by Seller, authorizing Seller to interact
directly with the provider(s) of these access telecommunications facilities.
When Seller acts as Customers agent, Customer is responsible for charges
including without limitation, monthly charges, usage charges, installation
charges, non-recurring charges, or applicable termination/cancellation
liabilities, of the provider(s) of telecommunications facilities to Seller POPs.

5.2.     In doing so, Seller shall be responsible for provisioning and the
initial testing of an interconnection (reasonably coordinated with Start of
Service) between such interexchange service set forth in the Service Order and
a Customer designated termination point ("Local Access"). Charges to Customer
for Local Access Service administered on behalf of Customer by Seller shall not
exceed charges Customer would otherwise pay the same Local Access Provider for
the relevant interconnection and/or service. Should Customer be able to provide
Seller with a quote for the same Local Access service from the Same Local
Access Provider, Seller agrees to match quote for such service.

5.3.     Seller may also provide other extraordinary service to Customer for
reasons including but not limited to: (a) Customer's request to expedite
Service availability to a date earlier than Seller's published installation
interval or a previously accepted Start Date; (b) Service redesign or other
activity occasioned by receipt of inaccurate information from Customer; (c)
reinstallation charges following any suspension of the Service for cause by
Seller; (d) Customer's request for use of routes or facilities other than those
selected by Seller for provision of the Service; and (e) other circumstances in
which extraordinary costs and expenses are generated by Customer and reasonably
incurred by Seller (services under this subsection 5.3 are collectively
referred to herein as ("Ancillary Services").

5.4.     Recurring and non-recurring charges to Customer for Local and
Ancillary Services shall be established as of Seller's acceptance of the
Service Order relevant thereto. RECURRING CHARGES FOR LOCAL ACCESS BILLING
ADMINISTERED BY SELLER AND CHARGED TO CUSTOMER SHALL BE SUBJECT TO ADJUSTMENT
AT SUCH TIMES AS SELLER SHALL DETERMINE, NOT TO EXCEED THE PREVAILING CHARGES
OF SUCH LOCAL ACCESS PROVIDERS AS WOULD OTHERWISE BE PAID DIRECTLY BY CUSTOMER
FOR THE RELEVANT INTERCONNECTION OR SERVICE.

6.0.     CHANGES IN SERVICE PARAMETERS.

6.1.     Cancellation of Services. Customer may cancel any Service or Ancillary
Service provided hereunder by providing written notification to Seller thereof
ninety 90) days in advance of the effective date of cancellation. In the event
of such cancellation, Customer shall not be required to pay to Seller a
cancellation charge as long as the circuit has been in service for at least
twelve (12) months, Customer's Revenue Commitment is still being met the
cancellation, and as long as Customer pays to Seller all termination liability
and one-time charges for local access or off-net, third party provided
facilities that are impacted by the cancellation. Customer shall also not be
required to pay to Seller a cancellation charge (except as set forth in Section
6.2 below) if Customer exercises the portability option defined in Section 6.2.
In the event the cancellation of the Service or Ancillary Service causes
Customer's monthly purchase of Services to fall below the Revenue Commitment
amount, Customer agrees to pay, the monthly difference between the Committed
Revenue amount and the amount actually billed until such time as Customer's
orders or billings exceed this Committed Revenue amount, and (ii) any
non-recurring payments not yet paid together with any termination liability
associated with Local Access. Customer agrees that the actual damages in the
event of such cancellation would be difficult or impossible to ascertain, and
that the cancellation charge in this Section 6.1 is intended, therefore, to
establish liquidated damages and is not intended as a penalty. Notwithstanding
the foregoing, and upon thirty (30) day's prior written notice to the other
party, either Customer or Seller shall have the right, without cancellation
charge or other liability to the other party, to cancel the affected portion of
any Service or Ancillary Service, if Seller is prohibited by governmental
authority from furnishing or Customer is prohibited from using such portion, or
if any material rate or term contained herein and relevant to the affected
portion of any Service or Ancillary Service is substantially changed by order of
the highest court of competent jurisdiction to adjudicate the matter, the
Federal Communications Commission, or other local, state or federal government
authority.


6.2      Portability. After any Service or Ancillary Service has been in effect
for a period of at least twelve (12) months, Customer shall have the option to
disconnect a circuit and turn up a new circuit as a replacement without
incurring a termination liability charge. The replacement circuit must be for
the same or greater term and the same or greater revenue as the circuit being
replaced. Should Customer exercise this portability option, Customer will be
liable for (i) all termination liability charges for local access or off-net,
third party provided facilities that are impacted by the move of the circuit;
and (ii) for all disconnect and one-time charges due to Seller under Seller's
standard disconnect and new installation rates and charges; and (iii) any
one-time local access charges and the new monthly recurring local access
charges. All circuits shall have portability within all areas served by Seller
on its network, subject to available capacity.

6.3      Service Migration. If Customer wishes to upgrade to a higher bandwidth
of service, Customer has forty-five (45) days from the turnup of the higher
bandwidth circuit in which to groom existing circuits onto the higher bandwidth
of service. During this forty-five (45) day period, the Customer will not be
billed for the higher bandwidth. After the forty-five (45) day period from
circuit turnup, billing for the higher bandwidth circuit commences, whether or
not if the existing circuits have been disconnected and groomed onto the larger
bandwidth.


7.0.     PAYMENT TERMS.

7.1.     Due Date and Invoice. All amounts stated on each monthly invoice are
due and payable thirty (30) days from the date of the invoice ("Due Date")
subject to postponement of disputed charges until resolution thereof as set
forth




                                  Page 4 of 24



<PAGE>   5

below. Customer agrees to remit payment to Seller at the remittance address. In
the event Customer fails to make full payment to the proper address by the Due
Date, Customer shall also pay a late fee in the amount of the lesser of one and
one-half percent (1 1/2) of the unpaid balance per month or the maximum lawful
rate under applicable state law which shall accrue from the Due Date. Customer
acknowledges and understands that all charges are computed exclusive of any
applicable federal, state or local use, excise, valued added, gross receipts,
sales and privilege taxes, duties, fees or similar liabilities (other than
general income or property taxes imposed on Seller), whether charged to or
against Seller, its suppliers or affiliates or Customer associated with the
Service or Ancillary Service provided to Customer ("Additional Charges"). Such
Additional Charges shall be paid by Customer in addition to all other charges
provided for herein.

Payment for all prorated monthly recurring charges (charges for monthly Service
or Ancillary Service provided for less than a calendar month), installation and
other non-recurring charges shall be billed following the receipt of any such
Services or Ancillary Service. Payment for all monthly recurring charges for
full months during which Service or Ancillary Service are to be provided shall
be due in advance.

If Customer in good faith disputes any portion of an invoice it must pay the
undisputed amount of the invoice on or before its Due Date and provide written
notice to Seller of the billing dispute within sixty (60) days thereafter. Such
notice must include documentation substantiating the dispute. Customer's failure
to notify Seller, of a dispute shall be deemed to be Customer's acceptance of
such charges. The parties will make a good faith effort to resolve billing
disputes as expeditiously as possible. If a dispute is resolved in favor of
Customer, Customer shall receive a credit on their next bill for the amount
determined to be due, if not, the additional sum due shall be payable no later
than 30 days following a dermination that it is due.

7.2.     Suspension of Service. In the event payment in full is not received
from Customer on or before sixty (60) days following the Due Date, Seller shall
have the right, after giving Customer ten (10) days notice, to suspend all or
any portion of the Services or Ancillary Service to Customer. If only a portion
of the Services or Ancillary Service are suspended and Customer does not cure
within ten days of delivery of notice of such partial suspension of Service,
Seller may suspend all or any additional portion of the Services or Ancillary
Service to Customer. Seller may continue suspension until such time as Customer
has paid in full all charges then due, including any late fees as specified
herein. Following such payment, Seller shall be required to reinstitute Service
or Ancillary Service to Customer only on the provision by Customer of
satisfactory assurance, in Seller's sole discretion which shall not be
unreasonably exercised of Customer's ability to pay for Service or Ancillary
Service. If Customer fails to provide such satisfactory assurance by a date
determined by and acceptable to Seller, Customer shall be deemed to have
canceled the Services or Ancillary Service provided under this Agreement
effective on the date of such suspension and shall remain liable for all
cancellation charges as set forth in Section 6.1. Further, if at any time there
is a material adverse change in Customer's creditworthiness or a material change
in Customer's financial position, then in addition to any other remedies
available to Seller, Seller may elect, in its sole discretion, to exercise one
or more of the following remedies: (i) cause the start of the Service or
Ancillary Service described in a previously executed Service Order to be
withheld; (ii) cease providing Service pursuant to a notice of suspension; (iii)
decline to accept a Service Order or other requests from Customer to provide
Service or Ancillary Service which Seller may otherwise be obligated to accept;
and/or (iv) condition its provision of Service or Ancillary Service or
acceptance of a Service Order on Customer's assurance of payment which shall be
a deposit or such other means to establish reasonable assurance of payment. An
adverse material change in Customer's creditworthiness shall include, but not be
limited to: (a) Customer's default of its financial obligations to Seller under
this or any other agreement with Seller; which default remains uncured. (b)
failure of Customer to make full payment of charges due hereunder on or before
the Due Date on three (3) or more occasions during any period of twelve (12) or
fewer months or Customer's failure to make such payment on or before the Due
Date in any two (2) consecutive months; (c) acquisition of Customer (whether in
whole or by majority or controlling interest) by an entity which is insolvent,
which is subject to bankruptcy or insolvency proceedings, which owes past due
amounts to Seller or any entity affiliated with Seller or which is a materially
greater credit risk than Customer; or, (d)


                                  Page 5 of 24


<PAGE>   6

Customer having filed for bankruptcy or insolvency proceedings or an involuntary
petition for Bankruptcy has been filed against Customer which has not been
deismissed within 60 days of the initial filing date. An adverse material change
in Customer's financial position shall include, but not be limited to: (a) a
decrease in net worth or working capital of five percent (5%) or greater; or,
(b) negative net worth or working capital. If Customer's financial statements
are not public information, Customer shall be required to provide financial
statements upon the request of Seller and Seller agrees hereby to hold such
financial statements in strict confidence subject only to the right to use such
financial statements for the purposes of this Agreement.

7.3.     Taxes. If any sales taxes, valued added taxes or similar charges or
impositions are asserted against Seller after, or as a result of, Customer's use
of Services or Ancillary Service by any local, state, national, international,
public or quasi-public governmental entity or foreign government or its
political subdivision, including without limitation, any tax or charge levied to
support the Universal Service Fund contemplated by the Telecommunications Act of
1996, Customer shall be solely responsible for such taxes, charges or
impositions. Customer agrees to pay any such taxes, charges or impositions and
hold Seller harmless from any liability or expense associated with such taxes,
charges or impositions.

7.4      Adjustments. Seller may make billing adjustments for a period of two
(2) years after the Due Date of an invoice, or two (2) years after the date a
service is rendered, whichever is later.

8.0.     GENERAL AGREEMENT.

8.1.     Warranty and Disclaimer of Warranty. Seller warrants that Services or
Ancillary Service shall be provided to Customer in accordance with the technical
parameters set forth in the applicable Service Schedule. Seller shall use
commercially reasonable efforts under the circumstances to remedy any delays,
interruptions, omissions, mistakes, accidents or errors in the Services or
Ancillary Service and restore such Services or Ancillary Service to comply with
the terms hereof. THE FOREGOING WARRANTY AND THE OUTAGE CREDITS REMEDY PROVIDED
TO CUSTOMER AS SET FORTH IN THE APPLICABLE SERVICE SCHEDULE FOR THE FAILURE TO
COMPLY WITH THIS WARRANTY ARE EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES OR
REMEDIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT LIMITATION,
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

8.2.     Limitation of Liability. IN THE EVENT OF ANY BREACH OF THIS AGREEMENT
OR ANY FAILURE OF THE SERVICES OR THE ANCILLARY SERVICES, WHATSOEVER, NO
PROVIDER (AS DEFINED IN SECTION 8.3) SHALL BE LIABLE FOR ANY DIRECT, INDIRECT,
CONSEQUENTIAL, SPECIAL, ACTUAL, INCIDENTAL, PUNITIVE OR ANY OTHER DAMAGES, OR
FOR ANY LOST PROFITS OF ANY KIND OR NATURE WHATSOEVER.

NEITHER CUSTOMER NOR ANY PROVIDER SHALL BE LIABLE TO THE OTHER FOR ANY
CONSEQUENTIAL, SPECIAL, INCIDENTAL, PUNITIVE OR ANY OTHER SIMILAR DAMAGES, OR
FOR ANY LOST PROFITS OF ANY KIND OR NATURE WHATSOEVER WITH RESPECT TO THIS
AGREEMENT OR FOR THE LOSS OR FAILURE OF THE SERVICES OR THE ANCILLARY SERVICES.

8.3.     Customer Content and Indemnity. Customer shall make all arrangements
with copyright holders, music licensing organizations, performers'
representatives or other parties for necessary authorizations, clearances or
consents with respect to transmission contents ("Consents"). Customer shall

referred to as "Providers")



                                  Page 6 of 24


<PAGE>   7

against and from any court, administrative or agency action, suit or similar
proceeding, whether civil or criminal, private or public, brought against
Providers arising out of or related to the contents transmitted hereunder (over
Seller's network or otherwise) including, but not limited to, claims, actual or
alleged, relating to any violation of copyright law, export control laws,
failure to procure Consents, failure to meet governmental or other technical
broadcast standards, or that such transmission contents are libelous,
slanderous, an invasion of privacy, pornographic, or otherwise unauthorized or
illegal. Seller may terminate or restrict any transmissions over the network if,
in its judgment, (a) such actions are reasonably appropriate to avoid violation
of applicable law; or (b) there is a reasonable risk that criminal, civil or
administrative proceedings or investigations based upon the transmission
contents shall be instituted against Providers. Customer agrees not to use
Services or Ancillary Service for any unlawful purpose, including without
limitation any use which constitutes or may constitute a violation of any local,
state or federal obscenity law.

8.4.     a) Customer and Seller shall, indemnify and hold harmless the other
against and from any and all claims for physical property damage, physical
personal injury or wrongful death to the extent that such arises out of the
negligence or willful misconduct of the respective indemnifying party, its
employees, agents, or contractors in connection with the provision of Services,
Ancillary Services or other performance.

         b) With respect to third parties that use Services or Ancillary Service

Schedule A

              Williams Network Asynchronous Transfer Mode ServiceTM

                               SERVICES & PRICING

This Asynchronous Transfer Mode Service Schedule ("ATMSS") is made as of this
__21st__ day of __May ______, 1998__, and is subject to that Carrier Services
Agreement No. _____________ (the "CSA") by and between Williams Communications,
Inc. d/b/a Williams Network Services, a Delaware corporation ("Williams"), and
Universal Access, Inc., an __ Illinois______________ corporation ("Customer").

1.       DESCRIPTION: Williams Network Asynchronous. Transfer Mode (ATM) is
         multi-service technology that provides integration of disparate
         networks onto a single communications infrastructure. ATM technology
         takes voice, data and video packets and divides them into equally
         sized, 53-byte cells and transmits them over the Williams Network ATM
         network. Williams Network ATM service is designed for two (2) primary
         applications. These applications include ATM transport and backbone
         connectivity. ATM transport provides multimedia aggregation and video
         transmission. Multimedia transmission is suited for transporting voice,
         data and video while video transmission is best designed for
         point-to-point video services. Backbone connectivity provides for the
         interconnection of local area networks (LANs) as well as
         interconnection of existing Network Access Points (NAPs) or private
         peering backbones.

2.       RATES & CHARGES: Williams Network ATM service has three basic rate
         elements; Access, Port Connections, and either Committed Bit Rate
         (CBR), or Variable Bit Rate (VBR) Permanent Virtual Circuits (PVCs) and
         Virtual Paths (VPs).


         2.1      Permanent virtual circuit (PVC) and Virtual Path (VP)
                  bandwidth charges. PVC and VP charges are based on the class
                  of service (CoS) and bandwidth selected. Bandwidth charges are
                  stated in Committed Information Rates (CIR) or Megabit per
                  second (Mbps) increments for one-way, or Simplex PVCs. CIR
                  increments are available in 1Meg increments up to 40Mbps for
                  DS3 ports, 5 Meg increments up to 150 Mpbs for OC3 ports and
                  25 Meg increments up to 600 Mbps for OC12 ports. Two Classes
                  of Service are offered; Constant Bit Rate (CBR) and Variable
                  Bit Rate non real time (VBRnrt). Monthly recurring charges for
                  port, PVCs and VPs are as follows:

2.1.1    ATM SERVICES

PRICING

ATM Transport includes both Recurring and Non-Recurring charges and discounts
based on term and monthly revenue commitment.

RECURRING CHARGES

ATM pricing is based on flat monthly fee assessed per node, which includes a
flat port charge based on the port connection speed, a charge for each PVCs CIR
going out from the port, and local access. ATM Transport Service is priced
simplex, meaning that a PVCs CIR is priced for both the ingress and egress CIR.

PARENT/SUBSIDIARY RELATIONSHIPS. If parent/subsidiary billing is provided, all
subsidiaries will contribute toward the overall commitment. The same discount,
based on the revenue commitment will apply for all subsidiary accounts.

CROSS PRODUCT DISCOUNTING. Revenue commitment levels are transferable to any of
the products in the product suite. For example, a private line revenue
commitment of $50,000 for 1 Year term can be used to determine the discount
applied for ATM services for the same term ($50,000 1 Year commitment would
equate to a.14% discount).

         written approval, order its own local access services. If Customer
         orders its own Local Access Services, Customer shall be billed
         directly by the supplier of such services and Williams shall not be
         responsible for billing any such charges.


3.       OFF-NET SERVICES PRICING: All services provided to Customer which are
         not on network facilities owned by Williams will be priced on an

               Williams Network Asynchronous Transfer Mode Service

                            Technical Specifications



1.0      Definition. Williams Network technical specifications are stated as an
         objective that the ATM network will perform in accordance with
         prevailing telecommunications industry standards. Williams Network will
         use reasonable efforts to remedy delays, interruptions, omissions or
         mistakes within the ATM network.

1.1      Performance Objectives. All service provided under the Williams Network
         Asynchronous Transfer Mode Service are measured using two variables:
         Network availability and Mean-time-to-repair.

1.2      Network Availability is a measurement of actual service time to stated
         service time. Network Availability objective: -99.99%

1.3      MTTR is the average time required to restore service and resume
         availability and is stated in terms of equipment and cable outages. The
         time is measured from the moment the outage is reported until the
         service is available and applies specifically to equipment outages or
         failures.

         MTTR objective:      -2 Hours (Equipment)

                              -6 Hours (First Fibers on Cable)

1.4      Calculation. Williams Network calculates network availability on
         customer action requests. The customer must notify Williams Network
         Customer Care Department and initiate an action request to determine if
         service level variables 1.2 & 1.3 were met.

[***] Additional Installation charges shall apply when Williams is required to
install equipment other than that normally required to provide the service or
when Customer requests special equipment. The above non-recurring charges are
subject to change, upon thirty (30) days prior written notice from Williams to
Customer.

3.       TERM OF SERVICES:

3.1      Upon acceptance of a Service Order, Williams shall confirm Customer's
         requested Start Date, or inform Customer of the estimated date for the
         delivery of each service. Williams shall use reasonable efforts to
         install each such service on or before the Start Date, but the
         inability of Williams to deliver a facility by such date shall not be a
         Default under this Agreement. If Williams fails to make any facility
         available within thirty (30) days after the Start Date, Customer's sole
         remedy shall be to cancel the Service Order which pertains to such
         Service by ten (10) calendar days prior written notice to Williams.

3.2      The effective date of each service (the "Service Effective Date") shall
         begin on the date on which Customer accepts delivery of such Service.
         If Customer fails to give written notice that the Service is in
         material non-compliance with the applicable technical specifications,
         as modified from time to time by Williams (the "Specifications") within
         fifteen (15) business days after notification to Customer by Williams
         that the Service is available, Customer shall be deemed to have
         accepted such Service, and the Service Effective Date shall commence as
         of the fifteenth (15th) business day following such notification by
         Williams. Following notice by Customer of material non-compliance as
         set forth above, Williams shall promptly take such reasonable action as
         is necessary to correct any such non-compliance in the Service and
         shall, upon correction, notify Customer of a new Service Effective
         Date.

4.       CHANGE OF SERVICES:

4.1      Change of Service Date. If Customer desires to change the date on which
         Customer has requested that Service be available, Customer may be
         charged a Change of Service Date Charge. Such charge will not apply to
         Customer's first change request, as long as such request is made within
         fifteen (15) business days prior to the original Requested Service
         Date. If Customer makes a second change, or such change is requested
         after fifteen (15) days prior to the original Requested Service Date,
         Customer will be charged Williams' then applicable Change of Service
         Date Charge. Customer will also be charged for any charges incurred by
         Williams from third party providers as a result of Customer's request
         for Change of Service Date.

4.2      Change of Service Order. If Customer requests a modification to the
         information contained in a Service Order (other than a Change of
         Service Date) prior to completion of installation of the Service,
         Customer will incur a Change of Service Order Charge. No charge will be
         incurred if the change is to the IXC part of the Service Order and is
         administrative in nature (i.e. billing address, contact information,
         etc.). A charge will be incurred if the administrative change relates
         to Local Access for which Williams is acting as agent.

         Change of Service Order charges will be lower if the Customer requests
         such change within five (5) business days after a Service Order has
         been accepted by Williams ("pre-engineering") and will be higher if
         such change is received after that time ("post-engineering"). Any
         expedited order will be considered to be in the post-engineering stage
         two (2) business days after the Service Order is accepted by Williams.

<PAGE>   20

4.3      Change of Service Charges. If Customer requests a change to Services
         after such Services have been installed, Customer will incur a Change
         of Service Charge. If such Change of Service is administrative in
         nature, Customer will not incur a charge, unless such administrative
         change applies to Local Access services which have been ordered by
         Williams as agent for Customer. In addition to the Change of Service
         Charge, Customer will be responsible for any charges due to
         re-engineering which is required as a result of Customer's request for
         Change of Service.

5.       OFF-NET SERVICES PRICING: All services provided to Customer which are
         not on network facilities owned by Williams will be priced on an
         individual case basis at the time Customer requests such service.

6.       OUTAGE CREDITS:

6.1      Customer acknowledges the possibility of an unscheduled, continuous
         and/or interrupted period of time when a Service or Services are
         "UNAVAILABLE" (as defined in the Specifications) for a continuous
         period of two (2) hours (hereafter an "OUTAGE"). An Outage shall begin
         upon recognition by Williams that the Service is interrupted. In the
         event of an Outage, Customer shall be entitled to a credit (the "OUTAGE
         CREDIT") at the rate of 1/720 of the monthly recurring charge for the
         IXC portion of the circuit for each hour in excess of the first two (2)
         consecutive hours that the affected service fails to conform to the
         Specifications.

6.2      Customer shall not receive an Outage Credit if the interruptions are
         (a) of a duration of less than two (2) consecutive hours, (b) caused by
         the negligence or willful misconduct of Customer or others authorized
         by Customer to use the services under this Agreement, (c) due to the
         failure of power, facilities, equipment, systems or connection not
         provided by Seller, (d) caused by the failure of access to Seller's
         fiber optic network, (e) resultant from scheduled maintenance where
         Customer has been notified of scheduled maintenance in advance, (f) due
         to a Force Majeure event as defined in Section 8.4 of the CSA.

6.3      All Outage Credits shall be credited on the next monthly invoice for
         the affected Service.

6.4      The Outage Credit described in this Section 6 of this PLSS shall be the
         sole and exclusive remedy of Customer in the event of any Outage, and
         under no circumstance shall an outage be deemed a Default under this
         Agreement.

<PAGE>   24
                TECHNICAL SPECIFICATIONS FOR PRIVATE LINE SERVICE



1.0      Interconnection Specifications

1.1      DS-3. DS-3 service is provided in accordance with ANSI Standard T1.102
         (formerly AT&T Compatibility Bulletin 119) and Technical Reference
         54014'4. DS-3 Service operates at 44.736 Mbps.

1.2      Optical SONET Services (OC-N). Optical SONET Services are provided in
         accordance with ANSI Standard T1.105. OC-3 Service operates at 155.520
         Mbps and is configured with 3 separate STS-1 signaling paths. OC-3C
         Service operates at 155.520 Mbps and is configured with 1 STS-3C
         signaling path (or 3 concatenated STS-1 signaling paths). OC-12 Service
         operates at 622.080 Mbps with 12 separate STS-1 signaling paths. OC-12C
         Service operates at 622.080 Mbps with 1 STS-12C signaling path (or 4
         separate STS-3C signaling paths). OC-48 Service operates at 9953.280
         Mbps and is configured with 48 separate STS-1 signaling paths.

2.0      Quality Standards

2.1      General. DS-3 and Optical SONET Service standards apply on a one-way
         basis between the Customer Premises Network Interface Points ("CPNIP")
         which are connected to Local Access between which DS-3 and Optical
         SONET Interexchange Service is provided (CPNIP to CPNIP or End-to-End)
         and exclude nonperformance due to force majeure or planned
         interruptions for necessary maintenance purposes. The actual end-to-end
         availability and performance of DS-3 and Optical SONET Service may be
         affected by the Customer provided equipment, dependent upon the type
         and quality of Customer equipment used. (Customer provided Local Access
         may not meet these specifications.)

2.2      Availability. Availability is a measurement of the percent of total
         time that service is operative when measured over a 365 consecutive day
         (8760 hour) period. DS-3 and Optical SONET Service is considered
         inoperative when there has been a loss of signal or when two
         consecutive 15 second loop-back tests confirm the observation of any
         severely errored seconds or a bit error rate equal to or worse than 1 x
         10-3. The Local Access availability standards for DS-3 and Optical
         SONET Services are established by the Local Access Provider. For
         Services on the Williams network, availability shall be 99.99% from
         point-of-presence ("POP") to POP measured over a one year period. For
         Services not on the Williams network, the off-net provider will
         establish availability. For multi-media services, availability will be
         the same as established by WorldCom, Inc.

2.3      Performance (% Error Free Seconds, while Available). Performance is
         noted in Error Free Seconds (EFS) which are a measure of the percentage
         of total seconds when measured over a consecutive 24 hour period that
         do not contain bit errors. Performance shall be measured on a one-way
         basis using a Pseudo Random Bit Sequence test pattern as defined in
         CCITT Recommendation 0.151. The Error Free Seconds standards for the
         Local Access for DS-3 and Optical SONET Service is established by the
         Local Access Provider. For Services on the Williams network, Error Free
         Seconds shall be 99.5% from POP to POP measured over a monthly period.
         For Services not on the Williams network, the off-net provider will
         establish Error Free Seconds. For multi-media services, Error Free
         Seconds will be as defined by WorldCom, Inc.

3.0      Maintenance

         Repair efforts will be undertaken upon notification of trouble by
         internal network surveillance and network surveillance and performance
         systems or by notification of trouble and release of all or part of the
         DS-3 or Optical SONET Service by the Customer for testing.

                  *        Mean Time to Restore (MTTR) is the average time
                           required to restore service and resume availability
                           and is stated in terms of equipment and cable
                           outages. The time is measured from the moment the
                           outage is reported until the service is available and
                           applies specifically to equipment outages or
                           failures.

                  *        MTTR objective:    -2 Hours (Equipment)
                                              -6 Hours (Equipment)

4.0      Calculation. Williams Network calculates network availability on
         customer action requests. The customer must notify Williams Network
         customer Care Department and initiate an action request to determine if
         service level variables 1.2 & 1.3 were met.

                                 AMENDMENT NO. 2



THIS AMENDMENT ("Amendment") is made and entered into effective this 1st day of
July, 1999, by and between WILLIAMS COMMUNICATIONS, INC. D/B/A WILLIAMS NETWORK
SERVICES ("Seller") and UNIVERSAL ACCESS, INC. ("Customer").

WHEREAS, Seller and Customer are parties to that certain Carrier Services
Agreement, Contract No. 98R0613.00 which is dated June 29, 1998 as amended by
Amendment No. 1 dated March 12, 1999, (together the "Agreement"); and

WHEREAS, Seller and Customer desire to amend the Agreement; and

NOW, THEREFORE in consideration of the foregoing premises and mutual promises
and covenants of the parties hereto, the receipt and sufficiency of which is
hereby acknowledged, Seller and Customer agree to amend the Agreement as
follows:

1.       Section 3.2 of the Agreement shall be amended to read as follows:

"The duration of this Agreement shall continue for a term of [***] years (the
"Initial Term") from the Effective Date. This Agreement shall thereafter
automatically renew for successive one-year periods (each, a "Renewal Term")
unless canceled by either party by giving written notice of such cancellation
not less than sixty (60) days before the end of the Initial Term, or any Renewal
Term. Unless Customer is in default at the end of any applicable cure period,
any Service being provided at the time of cancellation shall continue until the
end of such Service as specified in the applicable Service Order upon the terms
and conditions of this Agreement; provided that Customer may not order any new
Service without first renewing this Agreement. The charges for Services or
Ancillary Services during any such extension shall be the then current Seller
charges."

2.       Section 2.1 of the Private Line Service Schedule which is a part of the
Agreement shall be amended to read as follows:

         "2.1 IXC. DS-1, DS-3, OC-3 and OC-12 and OC-48 On-Net Private Line
         Services shall be provided at the following rates:

</TABLE>

         All other IXC rates will be determined on an individual case basis and
         will be set forth on the Service Order."

2.       The pricing set fourth in Section 2 of this Amendment shall not apply
to any existing Services being purchased by Customer (except as set forth in
paragraph 3 of this Amendment) and shall only apply to and be reflected on new
Service Orders placed by Customer after July 1, 1999. The above rates for new
Service Orders placed by Customer after July 1, 1999 shall be reflected on
Customer's July 1, 1999 invoice and Customer shall receive such pricing for any
new Service Orders placed during the remainder of the Term of the Agreement.


3.       Customer's Services ordered prior to July 1, 1999 (hereinafter
"Existing Services") shall be re-priced based on the pricing set forth in
Section 2 of this Amendment going forward after July 1, 1999, on a revenue
basis until Customer has achieved a total of [***] of new monthly recurring
revenue with Seller. Such re-pricing shall occur as follows: for every new
dollar of revenue that Customer generates with Seller after July 1, 1999,
Seller shall re-price a corresponding amount of Existing Services beginning
with Customer's most recently ordered circuits. (For example, if Customer
generates $10,000 of new business, Seller will re-price $10,000 of Existing
Services.) Customer shall receive such re-pricing of Existing Services the
month following the month in which the new Service Order was placed by Customer.



4.       Upon placement of a total of $[***] of new Service Orders by Customer
after July 1, 1999, all of Customer's Existing Services shall be re-priced at
the rates set forth in Section 2.1 of this Amendment No. 2. Customer shall
receive such re-pricing of all Existing Services the month following the month
in which the total of $[***] of new Service Orders are placed by Customer.


5.       Except as specifically amended herein, all terms, conditions and
provisions contained in the Agreement shall remain unchanged and in full force
and effect.

IN WITNESS WHEREOF, the parties have executed this Amendment on the day and year
first above set forth.

                                 Exhibit 10.20

                            GTE TELECOM INCORPORATED
                               CAPACITY AGREEMENT

This CAPACITY AGREEMENT is made and entered into as of August 20, 1999, by and
between GTE Telecom Incorporated (hereinafter referred to as "TELECOM" or
Party), a Delaware corporation with principal offices at 201 N. Franklin Street,
Suite 2400, Tampa, Florida 33602; and Universal Access, Inc. (hereinafter
referred to as "CUSTOMER" or Party), with offices at 100 N. Riverside Plaza,
Suite 2200, Chicago, Illinois 60606 for the provision of capacity and related
ancillary telecommunications services (hereinafter referred to as "Services") as
described herein and accepted by CUSTOMER under this Agreement, subject to the
terms and conditions contained herein. This Capacity Agreement together with any
Capacity Descriptions (as described in Section 1 below) accepted by TELECOM
pursuant to the terms hereof shall be referred to collectively as the
"Agreement".

1. SERVICE REQUESTS/CAPACITY DESCRIPTIONS: Requests for Services to be provided
hereunder shall be issued by CUSTOMER from time to time on TELECOM Capacity
Description Form(s) (hereinafter referred to as a "CD", a copy of which is
attached hereto and made a part hereof as Exhibit 1). Each CD shall reference
this Capacity Agreement by CA Number. Such CDs shall be effective when accepted
in writing by TELECOM and shall become part of this Agreement to the extent that
they specify the type of Service to be provided, quantity of circuits,
originating and terminating cities, requested service date, Service Term,
recurring and non-recurring charges for provision of Service, and other
information necessary for TELECOM to provide Service to the CUSTOMER. No action
by TELECOM (including, without limitation, provision of Service to CUSTOMER
pursuant to such CD) shall be construed as binding or estopping TELECOM with
respect to such term or condition, unless the CD containing said specific term
or condition has been duly executed by an authorized representative of TELECOM.

2. EFFECTIVE DATE AND APPLICATION OF THIS AGREEMENT: This Agreement shall be
effective between the parties as of the date first written above. The applicable
Rates and Charges are set forth in Exhibit 2 attached hereto and made a part
hereof. This Agreement shall apply exclusively to the Service provided to
CUSTOMER pursuant to the CD(s) identified with this Agreement and accepted by
TELECOM, for the Service Term stated therein and any automatic extensions
thereof. Services are provided subject to availability and TELECOM reserves the
right not to accept a CD under this Agreement at any time.

3. SERVICE TERM: (a) After a CD is accepted by TELECOM, a Firm Order
Confirmation Date ("FOC" Date) will be scheduled for Service installation. The
Service Term for Services subject to recurring charges and described in a CD
shall commence on the Firm Order Confirmation Date or the date upon which the
Service actually becomes available (the "In Service" Date), in conformity with
technical standards, whichever is later. The Service being provided hereunder
will be released to CUSTOMER for testing for seventy-two (72) hours prior to the
In Service Date.

 (b) TELECOM will make reasonable efforts to meet the CUSTOMER requested In
Service Date, however, the inability of TELECOM to install Service on or before
the date requested shall not be a Default under this Agreement. Except for any
installation delays caused by those events described in Section 12 below, in the
event Service installation is delayed for ninety (90) days beyond the CUSTOMER
requested In Service Date with respect to each Service ordered, then CUSTOMER's
sole remedy shall be cancellation of the CD which pertains to such Service upon
ten (10) calendar days prior written notice to TELECOM. Cancellation charges
described in Section 11 below shall not apply to such cancellation.

 (c) Upon expiration of the Service Term set forth in the CD, if CUSTOMER is not
then in Default under this Agreement, Service will automatically be extended for
continuing thirty (30) day periods and may be canceled by either party upon
thirty (30) calendar days prior written notice. Unless otherwise agreed to in
writing, the charges for Service during any such extension shall be the then
current TELECOM month to month rate for such Services.



                                                                               1

 (d) Price Protection Commencing [***] months after the effective date of the
Agreement and continuing thereafter semi-annually at the semi-annual date of the
Agreement, CUSTOMER may request TELECOM to review the prices contained in the
CD(s) entered into between the parties if the CUSTOMER has received an offer
from a qualified vendor (i.e., a vendor that is suitable to the CUSTOMER that
has obtained any required licenses, approvals or other authorizations) for all
Services provided hereunder which reduces the total prices by [***] or greater.
TELECOM reserves the right to review such an offer, subject to confidentiality
or non-disclosure obligations imposed on CUSTOMER in connection therewith, and
if warranted, will enter into negotiations with CUSTOMER for a reduction in
price.

6. CUSTOMER RESPONSIBILITIES: CUSTOMER has sole responsibility for installation,
testing, and operation of facilities, services, and equipment other than those
specifically provided by TELECOM under a duly accepted CD. In no event will the
untimely installation or non-operation of CUSTOMER's facilities, services, and
equipment (including local exchange access and customer premise equipment)
relieve CUSTOMER of its obligation to pay charges for Capacity or Ancillary
Service as of the In Service Date. Notwithstanding the immediately preceding
sentence, CUSTOMER may request one extension of the In Service Date for not more
than thirty (30) calendar days. Such requests for extension of local exchange
access together with the interexchange portion of the Service must be in writing
and must be received by TELECOM at least ten (10) calendar days prior to the
initial FOC Date established by TELECOM. Written requests for extension of the
In Service Date for the interexchange portion only must be and must be received
by TELECOM at least five (5) calendar days prior to the initial FOC Date
established by TELECOM. Any such extension will not relieve CUSTOMER of its
obligations to pay charges for any local access services ordered by TELECOM on
behalf of CUSTOMER as of the FOC Date first established by TELECOM.

7. PAYMENT OF CHARGES: (a) Subject to Section 8 below, all charges for Services
provided by TELECOM pursuant to this Agreement shall be specified in the CD
referred to in this Agreement.

(b) CUSTOMER shall pay each TELECOM invoice for Service in full, without
deduction or offset of any kind, within thirty (30) days after the date of
invoice ("Due Date"); provided however, if CUSTOMER in good faith disputes any
portion of an invoice, it must pay the undisputed amount on or before the Due
Date and provide written notice to TELECOM of the billing dispute within ninety
(90) days thereafter. Such notice must include documentation substantiating the
dispute. CUSTOMER's failure to notify TELECOM of a dispute shall be deemed to be
CUSTOMER's acceptance of such charges. The Parties will make a good faith effort
to resolve billing disputes as expeditiously as possible. If a dispute is
resolved in favor of CUSTOMER, CUSTOMER shall receive a credit on its invoice
within a commercially reasonable period of time for the disputed amount and any
related fees or penalties. All pro-rated monthly recurring charges (i.e.,
charges for monthly Services provided for less than a calendar month),
installation, and other non-recurring charges shall be payable on the Due Date.
All payment shall be made in US dollars. CUSTOMER agrees to timely remit payment
to TELECOM at the remittance address indicated on the TELECOM invoice to
CUSTOMER.

(c) Except for any reasonably disputed amount, in the event CUSTOMER fails to
pay TELECOM's invoice in full or remit payment at the proper address on or
before the Due Date, CUSTOMER shall pay a late fee in an amount equal to one and
one-half percent (1 1/2%) per month of the unpaid balance. The late fee will be
applied for the number of days from the payment Due Date up to and including the
date payment is received by TELECOM. Notwithstanding the foregoing, late fees
shall apply to, but shall not be due and payable for, amounts reasonably
disputed by CUSTOMER provided: (i) CUSTOMER notifies TELECOM of the basis of
such dispute in writing within sixty (60) days after the Due Date and (ii)
negotiates in good faith with TELECOM for the purpose of resolving such dispute.
In the event such dispute is resolved in favor of TELECOM, CUSTOMER will pay to
TELECOM the once disputed amount together with the applicable late fees. In the
event the dispute is resolved in favor of the CUSTOMER, CUSTOMER will receive a
credit for the amounts determined not to be owed together with a credit for the
applicable late fees. The Parties shall use their best efforts to negotiate in
good faith to resolve the disputed invoice within thirty (30) days of CUSTOMER's
written notice of such dispute. If such resolution is not attained or the time
to resolve the dispute is not extended by mutual agreement of the Parties, the
dispute shall be settled by arbitration as set forth below in this Agreement.

(d) TELECOM may, in order to safeguard its interests, require CUSTOMER which has
no credit history with TELECOM or habitually pays late to make a deposit prior
to or any time after the provision of Service to the CUSTOMER to be held by
TELECOM as a guarantee of the payment of the rates and charges. In lieu of such
a deposit, TELECOM may accept an unconditional, irrevocable Letter of Credit in
a form acceptable to TELECOM in an amount required by TELECOM, subject to
increase from time to time as CUSTOMER orders additional circuits hereunder. At
such time as the provision of the Service to CUSTOMER is terminated, the amount
of the deposit will be credited to the CUSTOMER's account and any credit balance
which may remain will be refunded. After the CUSTOMER has established a six (6)
month prompt payment record, such deposit may be refunded or credited to the
CUSTOMER account at any time prior to the termination of the provision of the
Service to CUSTOMER. In the event CUSTOMER pays a deposit as described above,
simple interest at the rate of six percent (6%) will be



                                                                               3
<PAGE>   4

applied to the deposit for the number of days from the date such deposit is
credited to the CUSTOMER'S account or the date the deposit is refunded by
TELECOM.

8. TAXES/ADDITIONAL CHARGES: (a) CUSTOMER acknowledges and understands that all
charges stated in the CD are computed by TELECOM exclusive of any applicable
federal, state, or local use, excise, gross receipts, sales, and privilege
taxes, duties, fees, including but not limited to applicable Universal Service
Fund contributions, or similar liabilities (other than general income or
property taxes), whether charges to or against TELECOM or CUSTOMER because of
the Service furnished by TELECOM ("Additional Charges"), and that such
Additional Charges shall be paid by CUSTOMER in addition to all other charges
provided for herein.

(b) Such taxes, surcharges or fees shall be separately stated on the invoice and
shall be paid directly to TELECOM at the same time as all other charges are due
and payable in accordance with this Agreement. Simultaneous with the signing of
this Agreement, CUSTOMER shall provide TELECOM with a valid Certificate of
Exemption from taxes that would otherwise be paid by CUSTOMER for all foreign,
federal, state, country and local taxes and fees, (if any) or other evidence
reasonably satisfactory to TELECOM that CUSTOMER is not subject to such taxes,
surcharges, or fees. TELECOM will invoice CUSTOMER for taxes that are not
covered by a valid tax exempt certificate properly filed with TELECOM.

9.      EARLY TERMINATION: (a) Either Party may terminate this Agreement if:

                (i)   the other Party ceases doing business as a going concern,
                      makes an assignment for the benefit of creditors, admits
                      in writing to its inability to pay its debts as they
                      become due; or

                (ii)  the other Party files a voluntary petition in bankruptcy,
                      is adjudicated a bankrupt or an insolvent; or

                (iii) the other Party files a petition seeking for itself any
                      reorganization, arrangement, composition, readjustment,
                      liquidation, dissolution or similar arrangement under any
                      present or future statute, law or regulation or files an
                      answer admitting the material allegations of a petition
                      filed against it in any such proceeding; or

                (iv)  the other Party consents or acquiesces in the appointment
                      of a trustee, receiver, or liquidator of it or of all or
                      any substantial part of its assets or properties, or it or
                      its shareholders shall take any action looking to its
                      dissolution or liquidation;

                (v)   the other Party breaches any material provision of this
                      Agreement, other than those related to payment of charges,
                      and fails to cure such breach within thirty (30) calendar
                      days after the receipt of notice thereof ("Default").

(b) Both Parties may terminate this Agreement upon mutual written consent.

10. SUSPENSION OF SERVICE: (a) In the event payment in full is not received from
CUSTOMER on or before the Due Date with respect to any undisputed amounts,
TELECOM shall have the right, after giving CUSTOMER fifteen (15) days written
notice via express courier service or registered mail, to suspend all or any
portion of Service until such time as CUSTOMER has paid in full all charges then
due, including any late fees as specified herein.

(b) Following such payment, TELECOM shall be required to reinstate Service to
CUSTOMER only upon CUSTOMER's provision to TELECOM of satisfactory assurance
(such as a deposit) of CUSTOMER's ability to pay for Service and CUSTOMER's
advance payment of the cost of reinstating Service. If CUSTOMER fails to make
such payment by a date determined by and acceptable to TELECOM, CUSTOMER will be
deemed to have canceled the suspended Service effective the date of the
suspension. Upon such termination, all balances become due and payable.

11. CANCELLATION OF SERVICE: (a) CUSTOMER may cancel a CD without liability if a
Service does not become available within ninety (90) days of the FOC Date as
described in Section 3 (b) above.



                                                                               4
<PAGE>   5
 (b)  After a CD is submitted to TELECOM by the CUSTOMER except as noted in
Section 3(b) above, CUSTOMER may cancel all or a portion of the Services ordered
upon written notice to TELECOM. The charges for such Cancellation are as
follows:


Prior to issuance of the FOC           No Cancellation Charges



Subsequent to issuance of the FOC      50% of applicable MRC for one (1) month
        up to the FOC Date             (maximum $20,000)


(c) It is agreed that TELECOM's damages in the event of a cancellation can be
difficult or impossible to ascertain. The provision for cancellation charges in
this subsection is intended to establish liquidated damages in the event of
Service cancellation and is not intended as a penalty. Unless otherwise stated
in the CD and specifically agreed to in writing by both Parties, in the event
CUSTOMER cancels existing Service prior to the end of the Service Term described
in the CD, CUSTOMER shall pay TELECOM an amount equal to the balance of the
monthly Service charges that otherwise would have become due for the unexpired
portion of the Service Term ("Cancellation Charges/Early Cancellation Charges").
Notwithstanding the immediately preceding sentence, no Early Cancellation
charges shall apply for the cancellation of the interexchange Service on
Telecom's Network for period that the CUSTOMER is responsible for the payment of
the Minimum Monthly Recurring Charge as set forth in Exhibit 2 - Rates and
Charges.

(d) Notwithstanding the foregoing, and upon thirty (30) days prior written
notice, either Party shall have the right, without cancellation charge or
liability, to cancel (i) an affected portion of the Service, if TELECOM is
prohibited by governmental authority from furnishing said portion, or (ii) an
affected portion of the Service if any material rate or term contained herein is
substantially changed by final order of a court of competent jurisdiction, the
Federal Communication Commission, or other local, state or federal government
authority.

12. FORCE MAJEURE: If either Party's performance of this Agreement or any other
obligation hereunder (other than the obligation to make payments for amounts
due) is prevented, restricted or interfered with by causes beyond their
reasonable control including but not limited to acts of God, fire, explosion,
vandalism, cable cut, storm, or other similar occurrence, any law, order,
regulation, direction, action or request of the United States government or
state or local government, or of any department, agency, commission, court,
bureau, corporation or other instrumentality of any one or more said
governments, or civil or military authority, or by national emergencies,
insurrections, riots, wars, strikes, lockouts or work stoppages or other labor
difficulties, actions or inactions of a third party provider or operator of
facilities employed in the provision of the Services, suppliers' failures,
shortages, breaches, or delays, then the affected Party shall be excused from
such performance on a day-to-day basis to the extent of such prevention,
restriction, or interference. The affected Party shall use reasonable efforts
under the circumstances to avoid or remove such causes of non-performance and
shall proceed to perform with reasonable dispatch whenever such causes are
removed or cease.

13. SERVICE WARRANTY: TELECOM warrants that it will provide the Service to
CUSTOMER in accordance prevailing telecommunication industry standards
(hereinafter "Technical Standards"). TELECOM will use reasonable efforts under
the circumstances to remedy any delays, interruptions, omissions, mistakes,
accidents or errors in any Service and restore the Service in accordance with
Technical Standards. THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL
OTHER WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT
LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.

14. LIMITATION OF LIABILITY: TELECOM shall not be liable for interruptions,
delays, errors, or defects in transmission caused by the CUSTOMER, or the
CUSTOMER's agents, end users, or by facilities or equipment provided by the
CUSTOMER or by equipment interconnected with the CUSTOMER. UNDER NO
CIRCUMSTANCES, WHETHER IN CONTRACT TORT OR OTHERWISE, SHALL EITHER PARTY BE
LIABLE FOR ANY INCIDENTAL, INDIRECT, CONSEQUENTIAL, SPECIAL, ACTUAL, PUNITIVE,
OR ANY OTHER DAMAGES OR ANY KIND OR NATURE WHATSOEVER REGARDLESS OF THE CAUSE OR
FORESEEABILITY THEREOF, INCLUDING BUT



                                                                               5



<PAGE>   6

NOT LIMITED TO DAMAGES ARISING FROM DELAY OR LOSS OF DATA, PROFITS, REVENUE OR
GOODWILL.

15. INDEMNIFICATION: Each Party agrees to release, indemnify, defend, and hold
harmless the other Party from losses, claims, demands, damages, expenses, suits,
or other actions, including reasonable attorney's fees, for personal injury,
including death of any person or persons, and for losses, damage, or destruction
of property, to the extent proximately caused by the negligence or willful
misconduct of the indemnifying Party, its employees, contractors, or agents.
This indemnity applies where the indemnifying Party's negligence or willful
misconduct is either the sole or the contributing cause of the injury, death, or
damage. This indemnity does not extend to any portion of the injury, death or
damage caused by either the sole or the contributing negligence of the
non-indemnifying Party or third parties. In the event parties other than
CUSTOMER shall have use or benefit of or shall be otherwise affected by the
Service provided through CUSTOMER, then CUSTOMER agrees to forever indemnify and
hold TELECOM and any third party provider or operator of the facilities employed
in the provision of the Service harmless from and against any and all claims,
demands, suits, actions, losses, damages, assessments or payments which may be
asserted by said parties, arising out of or related to any outage in Service.

16. NOTICES: Notices under this Agreement shall be in writing and shall be given
or made by telephonically confirmed facsimile transmissions, certified or
registered mail, express mail or other overnight delivery service, or hand
delivery, proper postage or other charges prepaid. Notices shall be sent to the

notice shall be deemed to have been given or made when actually received or
seventy-two (72) hours after being sent, whichever occurs first.

17. USE OF SERVICE/CAPACITY: (a) TELECOM's obligation to provide Services
specified herein is conditioned upon CUSTOMER not allowing the Services to be
used for any unlawful purpose or in violation of any governmental regulations or
authorizations. TELECOM shall have the right to limit, terminate or suspend
Service by written notice for improper use of the Service by CUSTOMER or any
activity by CUSTOMER, as determined in the sole discretion of TELECOM, that
threatens public health, safety, or welfare, or the integrity or reliability of
TELECOM's facilities or service to TELECOM's other customers.

(b) If CUSTOMER wishes to purchase capacity in an amount exceeding the
equivalent of OC-12 on any one route, then CUSTOMER represents and warrants that
it is not now, nor shall it become during the Term of this Agreement, a Capacity
Reseller (as defined below) with respect to any Services provided under this
Agreement. If CUSTOMER is or becomes during the Term of this Agreement a
Capacity Reseller with respect to any of the Services purchased hereunder, then
CUSTOMER may not purchase capacity in excess of the equivalent of one OC-12 on
any one route (referred to in this Section as the "Maximum Capacity"). If, at
the time CUSTOMER becomes a Capacity Reseller with respect to the Services
hereunder, CUSTOMER has ordered in excess of the Maximum Capacity, then CUSTOMER
shall immediately terminate all capacity in excess of the Maximum Capacity. Such
termination shall be subject to all applicable Early Cancellation/Termination
Charges. As used herein, a "Capacity Reseller" is any person or entity which, in
whole or in part, seeks to obtain telecommunications



                                                                               6
<PAGE>   7

capacity for the purpose of reselling or otherwise providing access thereto to
third parties for profit, whether or not such person or entity actually realizes
a profit as a result of such transaction. CUSTOMER's failure to comply with this
Section shall constitute a material default and shall be grounds for immediate
termination.

18. NONDISCLOSURE: CUSTOMER shall not use, except as provided herein, nor
disclose to any third party during the Term of this Agreement and for a period
of two (2) years thereafter, any of the terms and conditions relating to this
Agreement, including but not limited to the rates and charges set forth in this
Agreement, unless such disclosure is lawfully required by any federal
governmental agency, is otherwise required to be disclosed by law, or is
necessary in any proceeding establishing the rights and obligations under this
Agreement. Prior to any such required disclosure by CUSTOMER, CUSTOMER shall
provide TELECOM with adequate written notice so as to enable TELECOM to seek
appropriate protection. TELECOM reserves the right to terminate this Agreement
immediately upon written notice of any unpermitted third party disclosure
hereunder.

19. LICENSES, APPROVALS AND AUTHORIZATIONS: CUSTOMER represents that in all
jurisdictions in which it provides services that require licenses, approvals or
other authorizations it has obtained such licenses, approvals or other
authorizations from the appropriate governmental authority. Further, if required
by TELECOM, CUSTOMER shall provide proof of such licenses, approvals or other
authorizations. CUSTOMER shall immediately notify TELECOM in writing, in the
event CUSTOMER is prohibited, either on a temporary or permanent basis, from
continuing to provide its telecommunications services in any jurisdiction. In
such event, TELECOM reserves the right to terminate this Agreement.

20. RESOLUTION OF DISPUTES: The Parties desire to resolve disputes arising out
of this Agreement without litigation. Accordingly, except for action seeking a
temporary restraining order or injunction related to the purposes of this
Agreement, or suit to compel compliance with this dispute resolution provision,
the parties agree to submit the dispute to a single arbitrator for resolution by
binding arbitration pursuant to the Commercial Arbitration Rules of the American
Arbitration Association. A Party may demand such arbitration in accordance with
the procedures set out in those rules. Discovery shall be controlled by the
arbitrator. Each Party shall bear its own costs of these procedures. A Party
seeking discovery shall reimburse the responding Party the costs of production
of documents (to include search time and reproduction costs). The Parties shall
equally split the fees of the arbitration and the arbitrator.

21. GENERAL PROVISIONS: (a) Other Documents CUSTOMER will execute such other
documents, provide such information, and affirmatively cooperate with TELECOM,
all as may be reasonably required by TELECOM and relevant to providing the
Service. In particular, CUSTOMER accepts the responsibility for providing
TELECOM with special access surcharge exemption forms as may be required by the
local exchange carrier and as applicable, TELECOM's Universal Service Fund
exemption form.

(b) Non-Waiver The failure of either Party to give notice of default or to
enforce or insist upon compliance with any of the terms or conditions of this
Agreement, the waiver of any term or condition of this Agreement or the granting
of an extension of time for the performance shall not constitute the permanent
waiver of any term or condition of this Agreement and this Agreement and each of
its provisions shall remain at all times in full force and effect until modified
by the Parties in writing.

(c) Relationship of the Parties The provision of Service will not create a
partnership or joint venture between the parties or result in a joint
communications service offering to third parties.

(d) Enforcement In the event suit is brought or an attorney is retained by
either Party to enforce terms of this Agreement or to collect money damages for
breach hereof or by TELECOM to collect any monies due hereunder, then the
prevailing Party shall be entitled to recover, in addition to any other remedy,
reimbursement for reasonable attorneys' fees, court costs, costs of
investigation, and other related expenses incurred in connection therewith.

(e) Modification No subsequent agreement shall change, modify or discharge this
Agreement, in whole or in part, unless such agreement is in writing and signed
by authorized representatives of both parties.

(f) Assignment This Agreement shall be binding upon and shall inure to the
benefit of the parties hereto and their respective successors or assigns,
provided, however, that CUSTOMER shall not assign



                                                                               7


<PAGE>   8

or transfer its rights or obligations under this Agreement without the prior
written consent of TELECOM, which consent shall not be unreasonably withheld,
and further provided that any assignment or transfer without such consent shall
be deemed void and shall entitle TELECOM to terminate the Service provided
hereunder, at its option, upon ten (10) days prior written notice.
Notwithstanding any other language contained in this Agreement, either Party
may, without further permission but upon proper notice to the other Party,
assign the Agreement to any affiliated entity or successor in interest whether
by merger, reorganization, or transfer of all or substantially all of its
assets.

(g) Governing Law This Agreement shall be a contract between TELECOM and
CUSTOMER and the terms hereof shall be construed under the laws of the State of
Florida without regard to choice of law principles.

(h) Severability If any part or any provision of this Agreement shall be invalid
or unenforceable under applicable law, said part shall be ineffective to the
extent of such invalidity only, without in any way affecting the remaining parts
of said provision or the remaining provisions of this Agreement, and the
CUSTOMER and TELECOM hereby agree to negotiate with respect to any such invalid
or unenforceable part to the extent necessary to render such part valid and

                            SERVICE LEVEL OBJECTIVES

TELECOM will make commercially reasonable efforts to meet the following Service
Level Objectives:

(a)     Mean Time to Repair - less than or equal to four (4) hours for DS3's,
        OC3's, OC12's.

(b)     Network Availability for "on net" private line Services:

        99.95% for Linear Network

        99.99% for SONET Ring Network (when available).

Credits for Outages:

(i) For the purposes of this Agreement, a circuit shall be deemed to be in an
"Outage" condition if, following the start of Service while CUSTOMER is actually
using or attempting to use such circuit, the circuit and becomes unavailable as
defined above.

CUSTOMER's request for credit for Outages must be submitted to TELECOM in
writing within thirty (30) calendar days of such Outage. TELECOM will respond to
each of CUSTOMER's requested credits and upon Outage verification by TELECOM,
TELECOM will apply the applicable credit to the next or subsequent Service
invoice. Service Outages do not include (a) Outage periods when CUSTOMER has
released the Service to TELECOM for maintenance purposes or to make
rearrangements or CUSTOMER requested changes in the Service; (b) circuits
outside the contiguous U.S.; (c) any circuits ordered by CUSTOMER from another
telecommunications service provider or carrier; (d) any local access circuits
ordered by or on behalf of CUSTOMER; (e) failure of CUSTOMER applications,
equipment or facilities, (f) acts or omissions of CUSTOMER, or any use or user
of the Service authorized by CUSTOMER or (g) reasons of Force Majeure. [***] No
credit is allowed for Service Outages of less than thirty (30) minutes. Outages
will be credited to CUSTOMER in half hour multiples for each half hour or major
fraction thereof, from the time TELECOM receives notification until Service is
restored. The credit shall not be applicable for the time that TELECOM stands
ready to repair the Service and CUSTOMER does not provide access to TELECOM to
perform such repair and restoration work. The credit allowance for an Outage or
a series of Outages shall not exceed the current monthly recurring charge for
such Service. The credit provided for in this Section shall be TELECOM's sole
liability and CUSTOMER's sole and exclusive remedy in the event of any Outage or
Service interruption.

(ii) Chronic Outages In the event that a single circuit experiences three (3)
or more Outages of fifteen (15) minutes duration or longer during any thirty
(30) day period, CUSTOMER may declare that the circuit has a chronic problem.
Upon written notice from CUSTOMER, TELECOM will have thirty (30) days to correct
the chronic problem. In the event that the problem is not corrected within
thirty (30) days of TELECOM's receipt of written notice, CUSTOMER may cancel
this circuit without any additional charges or any further liability and such
cancellation will be CUSTOMER's sole and exclusive remedy for chronic Outages.

Credit allowances will be calculated on a monthly basis and the applicable
Outage credit by circuit will be included in TELECOM's invoice. CUSTOMER shall
have thirty (30) days from date of receipt of the invoice to contest the credit
allowance offered by TELECOM.



                                                                              12

SECTION 1. CUSTOMER ORDERS

1.1 SUBMISSION OF CUSTOMER ORDERS. Customer may submit to Level 3 Customer Order
forms requesting the provision of Service. Each Customer Order form shall be
submitted on a form designated by Level 3. Level 3 shall confirm the accuracy of
information on the Customer Order form and the availability of the Services
requested. Level 3's delivery of a Firm Order Commitment respecting such
Services shall constitute Level 3's acceptance of the Customer Order for such
Services. The Customer Order form and attachments shall set forth the Service,
the locations for delivery of same, the prices to be charged for same and any
applicable term and/or Revenue Commitment.

1.2 UNDERTAKING OF LEVEL 3. If Level 3 issues a Firm Order Commitment respecting
Services, Level 3 will furnish such Services in accordance with these Terms and
Conditions and any Customer Orders executed by Customer. All title to equipment
or materials used to deliver the Services (except as otherwise expressly agreed)
shall be and remain with Level 3.

SECTION 2. BILLING AND PAYMENT

2.1 PAYMENT AND RENDERING OF BILLS. Level 3 shall bill all charges incurred by
and credits due to Customer on a monthly basis (unless otherwise agreed in
writing by Level 3 and Customer). Level 3 shall bill in advance charges for all
Services to be provided during the ensuing month except for charges which are
dependent upon usage of Service (which charges shall be billed in arrears).
Adjustments for the quantities of Service established or discontinued in any
billing period will be prorated to the number of days based on a 30-day month.
Level 3 will, upon request and if available, furnish such detailed information
as may reasonably be required for verification of the bill.

2.2 PAYMENT OF BILLS. All bills are due upon receipt thereof by Customer, and
become past due thirty (30) days thereafter. The unpaid balance of any past due
bills shall bear interest at a rate of 1.5% per month (prorated on a daily
basis), or the highest rate allowed by law, whichever is less. Interest will be
applied for the number of days from the date the bill became past due to and
including the date that payment is received by Level 3.

2.3 TAXES AND FEES. Except for taxes based on Level 3's net income and except
with respect to ad valorem personal and real property taxes imposed on Level 3's
property, Customer shall be responsible for payment of all sales, use, gross
receipts, excise, access, bypass, franchise or other local, state and federal
taxes, fees, charges, or surcharges, however designated, imposed on or based
upon the provision, sale or use of the Services delivered by Level 3 (including,
but not limited to, taxes and fees lawfully assessed by nations outside of the
United States). Any taxes shall be separately stated on Customer's bill. Any
state or local tax, fee, charge, or surcharge shall be payable only for Services
that are subject to such imposition.



                                  Page 1 of 17
<PAGE>   2

2.4 REGULATORY AND LEGAL CHANGES. In the event of any change in applicable law
or regulation that materially increases the cost of delivery of Service, Level 3
and Customer shall negotiate regarding the rates charged to Customer to reflect
such increase in cost and, in the event that the parties are unable to reach
agreement respecting new rates within thirty (30) days after Level 3's delivery
of written notice requesting renegotiation, then (a) Level 3 may pass such
increased costs through to Customer, and (b) Customer may terminate the affected
Customer Order upon no less than sixty (60) days' prior written notice without
payment of any applicable termination charge

2.5 DISPUTED BILLS. In the event that Customer disputes any portion of the
charges contained in a bill, Customer must pay the undisputed portion of the
invoice in full and submit a documented claim for the disputed amount. All
claims must be submitted to Level 3 within sixty (60) days of receipt of billing
for those Services. If Customer does not submit a claim within such period and
in the manner stated above, Customer waives all rights to dispute such charges.

2.6 CREDIT APPROVAL AND DEPOSITS. Customer shall provide Level 3 with credit
information as requested in advance of the commencement of delivery of Service
under any Customer Order. Delivery of Service is subject to credit approval.
Level 3 may require any Customer to make a deposit as a condition to Level 3's
acceptance of any Customer Order submitted by Customer, or as a condition to
Level 3's continuation of Service under any Customer Order (but only when
Customer's consumption of Service materially exceeds Customer's anticipated use
or when, in Level 3's reasonable discretion, such deposit is required in order
to secure Customer's continued payment obligation), which deposit shall be held
by Level 3 as security for payment of charges. A deposit may not exceed the
actual or estimated rates and charges for the Service for a two (2) month
period. At such time as the provision of Service to Customer is terminated, the
amount of the deposit will be credited to Customer's account and any credit
balance which may remain will be refunded.

2.7 FRAUDULENT USE OF SERVICES. Customer shall be solely responsible for all
charges incurred respecting the Services, even if such charges were incurred
through or as a result of fraudulent or unauthorized use of the Services, unless
Level 3 has actual knowledge of such fraudulent or unauthorized use and fails to
inform Customer thereof or otherwise limit or preclude such use. Nothing in this
Section 2.7, however, shall be construed to obligate Level 3 to detect or report
unauthorized or fraudulent use of Services.

SECTION 3. CANCELLATION OF CUSTOMER ORDERS

3.1 CANCELLATION OF CUSTOMER ORDER BY LEVEL 3.

A. For nonpayment: Level 3 may, upon fourteen (14) days' written notice,
discontinue Service without incurring any liability when there is an unpaid
balance for Service that is past due.

B. For any violation of law or of any of the provisions governing the furnishing
of Service: Any Customer Order shall be subject to cancellation, without notice,
for any violation of any law, rule, regulation or policy of any government
authority having jurisdiction over Service or by reason of any order or decision
of a court or other government authority having jurisdiction which prohibits
Level 3 from furnishing such Service.

C. For other causes: Any Customer Order shall be subject to cancellation, upon
fourteen (14) days' prior written notice, in the event of a breach of a Customer
Order, fraudulent use of the Service, or fraud or misrepresentation in any
submission of information required in a Customer Order or any other information
submitted to Level 3.

D. For any Customer filing of bankruptcy or reorganization or failing to
discharge an involuntary petition therefor within sixty (60) days after filing:
Level 3 may immediately discontinue or suspend delivery of Service without
incurring any liability.

E. For consumption of Services that materially exceeds Customer's credit limit:
Level 3 may, upon fourteen (14) days prior written notice and provided Customer
has not provided additional security for payment which is sufficient in Level
3's reasonable discretion, discontinue or suspend delivery of Service without
incurring any liability.

3.2 EFFECT OF CANCELLATION. Upon Level 3's discontinuance of Service to Customer
under any of the foregoing subparagraphs, Level 3 may, in addition to all other
remedies that may be available to Level 3 at law or in equity or under any other
provision of a Customer Order, assess and collect from Customer any termination
charge set forth herein (to the extent applicable).

3.3 RESUMPTION OF SERVICE. If Service has been discontinued by Level 3, and
Customer requests that Service be restored, Level 3 shall have the sole and
absolute discretion to restore such Service only after satisfaction of such
conditions as Level 3 determines to be required for its protection. Nonrecurring
charges apply to restoration of Service.

SECTION 4.  DELIVERY OF SERVICES

4.1 LEVEL 3 ACCESS TO PREMISES. Customer shall allow Level 3 continuous and
reasonable access to the Premises to the extent reasonably determined by Level 3
to be appropriate to the installation, inspection and maintenance of equipment,
facilities and systems relating to the Service. Level 3 shall notify Customer
two (2) business days in advance of any regularly scheduled maintenance that
will require access to the Premises.

4.2 LEVEL 3 FACILITIES. Level 3 will use reasonable efforts to maintain the
facilities and equipment required to deliver Service. Customers shall not and
shall not permit others to rearrange, disconnect, remove, attempt to repair, or
otherwise tamper with any of the facilities or equipment installed by Level 3,
except upon the written consent of Level 3. Equipment provided or installed at
the Premises by Level 3 for use in connection with the Service shall not be used
for any purpose other than that for which Level 3 provided it. In the



                                  Page 2 of 17
<PAGE>   3

event that Customer or a third party attempts to operate or maintain any Level
3-owned equipment without first obtaining Level 3's written approval, in
addition to any other remedies of Level 3 for a breach by Customer of Customer's
obligations hereunder, Customer shall pay Level 3 for any damage to Level
3-owned equipment caused thereby. Customer shall be responsible for the payment
of service charges in the event that maintenance or inspection of the equipment
is required as a result of Customer's breach of this Section. Level 3 shall, in
the event that such expenses are incurred, deliver to Customer a written invoice
therefor. In no event shall Level 3 be liable to Customer or any other person
for interruption of Service or for any other loss, cost or damage caused or
related to improper use or maintenance of Level 3-owned equipment.

these Terms and Conditions shall be construed to obligate Customer to submit, or
Level 3 to accept, Customer Orders.

                              TELEPHONY COLOCATION

The following Terms and Conditions shall be applicable to Customer's use of
space within Level 3 facilities used for the purpose of colocating
telecommunications equipment (the "Space") ordered by Customer under any
Customer Order.

1. Upon execution and performance of Customer's obligations under a Customer
Order for use of Space, Customer shall be granted the right to occupy the Space
identified therein. Customer may submit multiple Customer Orders requesting use
of different Space, each of which shall be governed by the terms hereof.

2. Customer shall be permitted to use the Space only for placement and
maintenance of communications equipment which shall be interconnected to the
network services offered by Level 3. Customer may use the Space to cross connect
to the facilities of other communications carriers if and only if Level 3 cannot
or will not provide such services to Customer on commercially reasonable terms.
The nonrecurring and monthly recurring charges for the Space and any Services
ordered by Customer shall be set forth in each Customer Order.

3. During the term for use of the Space set forth in each Customer Order,
Customer shall commit to use, order and pay for Level 3 network communications
services (not including monthly recurring fees charged for the use of the Space)
with monthly recurring charges of at least $2,000.00 for each cabinet of Space
ordered by Customer. Customer shall achieve the minimum service level no later
than six (6) months after submission and acceptance of each Customer Order.
Level 3 may terminate use of the Space in the event that Customer does not
satisfy this minimum service commitment.

4. Level 3 shall perform such janitorial services, environmental systems
maintenance, power plant maintenance and other actions as are reasonably
required to maintain the facility in which the Space is located in good
condition which is suitable for the placement of communications equipment.
Customer shall maintain the Space in orderly and safe condition, and shall
return the Space to Level 3 at the conclusion of the term set forth in the
Customer Order in the same condition (reasonable wear and tear excepted) as when
such Space was delivered to Customer. EXCEPT AS EXPRESSLY STATED HEREIN OR IN
ANY CUSTOMER ORDER, THE SPACE SHALL BE DELIVERED AND ACCEPTED "AS IS" BY
CUSTOMER, AND NO REPRESENTATION HAS BEEN MADE BY LEVEL 3 AS TO THE FITNESS OF
THE SPACE FOR CUSTOMER'S INTENDED PURPOSE.

5. The term of use of the Space shall begin on the later to occur of the date
requested by Customer or the date that Level 3 completes the build-out of the
Space. Customer's use of the Space beyond the initial term shall be on a
month-to-month basis, unless Customer and Level 3 have agreed in writing to a
renewal of the right to use such Space.

6. Level 3 shall use reasonable efforts to complete the build-out and make the
Space available to Customer on or before the date requested by Customer. In the
event that Level 3 fails to complete the build-out within sixty (60) days of the
date requested by Customer, then Customer may terminate its rights to use such
Space and receive a refund of any fees paid for the use or build-out of such
Space.

7. Customer shall abide by any posted or otherwise communicated rules relating
to use of, access to, or security measures respecting the Space. In the event
that unauthorized parties gain access to the Space through access cards, keys or
other access devices provided to Customer, Customer shall be responsible for any
damages incurred as a result thereof. Customer shall be responsible for the cost
of replacing any security devices lost or stolen after delivery thereof to
Customer. In addition, Level 3 shall have the right to terminate Customer's use
of the Space in the event that: (a) Level 3's rights to use the facility within
which the Space is located terminates or expires for any reason; (b) Customer
has violated the terms hereof or any Customer Order submitted hereunder; (c)
Customer makes any material alterations to the Space without first obtaining the
written consent of Level 3; (d) Customer allows personnel or contractors to
enter the Space who have not been approved by Level 3 in advance; or (e)
Customer violates any posted or otherwise communicated rules relating to use of
or access to the Space. Level 3 shall use reasonable efforts to notify Customer
of any events that may result in termination of the use of the Space.

8. Customer shall pay all monthly recurring fees, cross-connect fees, power
charges and nonrecurring fees specified in each Customer Order for the agreed
term thereof. In the event that Customer terminates a Customer Order for Space
or in the event that the Customer Order is terminated due to a failure of
Customer to satisfy the requirements set forth herein or in the Customer Order
prior to the end of the agreed term, Customer shall pay a termination charge
equal to the costs incurred by Level 3 in returning the Space to a condition
suitable for use by other parties, plus the percentage of the monthly recurring
fees for the terminated Space calculated as follows:


A.    100% of the monthly recurring fees that would have been charged for the
Space for months 1-12 of the agreed term; plus



B.    75% of the monthly recurring fees that would have been charged for the
Space for months 13-24 of the agreed term; plus

9. Level 3 reserves the right to change the location or configuration of the
Space, provided, however, that Level 3 shall not arbitrarily or discriminatorily
require such changes. Level 3 and Customer shall work in good faith to minimize
any disruption in Customer's services that may be caused by such changes in
location or configuration of the Space.

10. Prior to occupancy and during the term of use of any Space, Customer shall
procure and maintain the following minimum insurance coverage: (a) Workers'
Compensation in compliance with all applicable statutes of appropriate
jurisdiction. Employer's Liability with limits of $500,000 each accident; (b)
Commercial General Liability with combined single limits of $1,000,000 each
occurrence; and (c) "All Risk" Property insurance covering all of Customers
personal property located in the Space. Customer's Commercial General Liability
policy shall be endorsed to show Level 3 (and any underlying property owner, as
requested by Level 3) as an additional insured. All policies shall provide that
Customer's insurers waive all rights of subrogation against Level 3. Customer
shall furnish Level 3 with certificates of insurance demonstrating that Customer
has obtained the required insurance coverages prior to occupancy of the Space.
Such certificates shall contain a statement that the insurance coverage shall
not be materially changed or cancelled without at least thirty (30) days' prior
written notice to Level 3. Customer shall require any contractor entering the
Space on its behalf to procure and maintain the same types, amounts and coverage
extensions as required of Customer above.

11. The liability of Level 3 for damages arising out of the furnishing of Space,
including but not limited to mistakes, omissions, interruptions, delays,
tortious conduct or errors, or other defects arising out of the failure to
furnish Space, whether caused by acts of commission or omission, shall be
limited to a prorated refund of the charges paid by Customer for the use of the
Space hereunder. The extension of such refunds shall be the sole remedy of
Customer and the sole liability of Level 3.

                              TERMS AND CONDITIONS
                                  IP COLOCATION

The following Terms and Conditions shall be applicable to Customer's use of
space within Level 3 facilities used for the purpose of colocating equipment
used for connection to the internet (the "Space") ordered by Customer under any
Customer Order.

1. Upon execution and performance of Customer's obligations under a Customer
Order for use of Space, Customer shall be granted the right to occupy the Space
identified therein. Customer further agrees to purchase certain communications
services ("Services") identified in Customer Orders for such Services submitted
by Customer hereunder. Customer may submit multiple Customer Orders requesting
use of different Space, each of which shall be governed by the terms hereof.
Services ordered by Customer shall at all times be used by Customer in
compliance with Level 3's then-current Acceptable Use Policy and Privacy Policy,
as amended by Level 3 from time to time and which are available through Level
3's web site.

2. Customer shall be permitted to use the Space only for placement and
maintenance of computer and/or communications equipment which shall be
interconnected to the Services provided by Level 3. Customer may use the Space
to cross connect to the facilities of other communications carriers if and only
if Level 3 cannot or will not provide such services to Customer on commercially
reasonable terms. The nonrecurring and monthly recurring charges for the Space
and the Services shall be set forth in each Customer Order.

3. During the term for use of the Space set forth in each Customer Order,
Customer shall commit to use, order and pay for the following amounts of
bandwidth provided by Level 3: (a) for Customers using cabinets, at least 1 Mbps
of bandwidth for each partial cabinet and at least 2 Mbps of bandwidth for each
full cabinet of Space ordered by Customer; and (b) for Customers using private
rooms, at least 1 Mbps of bandwidth for each 10 square feet of Space ordered by
Customer. Customer shall achieve the minimum service level immediately after
submission and acceptance of each Customer Order. Level 3 may terminate use of
the Space in the event that Customer does not satisfy this minimum service
commitment.

4. Level 3 shall perform such janitorial services, environmental systems
maintenance, power plant maintenance and other actions as are reasonably
required to maintain the facility in which the Space is located in good
condition which is suitable for the placement of communications equipment. In
addition, Customer may order and pay for Level 3 to perform certain limited
("remote hands") maintenance services on Customer's equipment within the space,
which shall be performed in accordance with Customer's directions. "Remote
hands" maintenance services includes power cycling equipment. Level 3 shall in
no event be responsible for the repair, configuration or tuning of equipment, or
for installation of Customer's equipment (although Level 3 will provide
reasonable assistance to Customer in such installation). Customer shall maintain
the Space in orderly and safe condition, and shall return the Space to Level 3
at the conclusion of the term set forth in the Customer Order in the same
condition (reasonable wear and tear excepted) as when such Space was delivered
to Customer. EXCEPT AS EXPRESSLY STATED HEREIN OR IN ANY CUSTOMER ORDER, THE
SPACE SHALL BE DELIVERED AND ACCEPTED "AS IS" BY CUSTOMER, AND NO REPRESENTATION
HAS BEEN MADE BY LEVEL 3 AS TO THE FITNESS OF THE SPACE FOR CUSTOMER'S INTENDED
PURPOSE.

5. The term of use of the Space shall begin on the later to occur of the date
requested by Customer or the date that Level 3 completes the build-out of the
Space. Customer's use of the Space beyond the initial term shall be on a
month-to-month basis, unless Customer and Level 3 have agreed in writing to a
renewal of the right to use such Space. Customer hereby agrees to pay for the
Space and Services for the period of time specified in each Customer Order,
which period shall commence when both completion of the build-out of the Space
and initiation of delivery of such Services has occurred. The rates and other
charges set forth in each Customer Order are established in reliance on the term
commitment made therein. In the event that Customer terminates a Customer Order
for Space or in the event that the Customer Order is terminated due to a failure
of Customer to satisfy the requirements set forth herein or in the Customer
Order prior to the end of the agreed term, Customer shall pay a termination
charge equal to the costs incurred by Level 3 in returning the Space to a
condition suitable for use by other parties, plus the percentage of the monthly
recurring fees for the terminated Space calculated as follows:


a.   100% of the monthly recurring fees that would have been charged for the
Space for months 1-12 of the agreed term; plus

b.   75% of the monthly recurring fees that would have been charged for the
Space for months 13-24 of the agreed term; plus

c.   50% of the monthly recurring fees that would have been charged for the
Space for months 25 through the end of the agreed term.


6. Level 3 shall use reasonable efforts to complete the build-out and make the
Space available to Customer on or before the date requested by Customer. In the
event that Level 3 fails to complete the build-out within sixty (60) days of the
date requested by Customer, then Customer may terminate its rights to use such
Space and receive a refund





                                 Page 11 of 17
<PAGE>   12

of any fees paid for the use or build-out of such Space.

7. Customer shall abide by any posted or otherwise communicated rules relating
to use of, access to, or security measures respecting the Space. In the event
that unauthorized parties gain access to the Space through access cards, keys or
other access devices provided to Customer, Customer shall be responsible for any
damages incurred as a result thereof. Customer shall be responsible for the cost
of replacing any security devices lost or stolen after delivery thereof to
Customer. In addition, Level 3 shall have the right to terminate Customer's use
of the Space or the Services in the event that: (a) Level 3's rights to use the
facility within which the Space is located terminates or expires for any reason;
(b) Customer has violated the terms hereof or of any Customer Order submitted
hereunder; (c) Customer makes any material alterations to the Space without
first obtaining the written consent of Level 3; (d) Customer allows personnel or
contractors to enter the Space who have not been approved by Level 3 in advance;
or (e) Customer violates any posted or otherwise communicated rules relating to
use of or access to the Space. Level 3 shall use reasonable efforts to notify
Customer of any events that may result in termination of the use of the Space or
delivery of Services.

8. Level 3 reserves the right to change the location or configuration of the
Space, provided, however, that Level 3 shall not arbitrarily or discriminatorily
require such changes. Level 3 and Customer shall work in good faith to minimize
any disruption in Customer's services that may be caused by such changes in
location or configuration of the Space.

9. Level 3 provides only access to the Internet; Level 3 does not operate or
control the information, services, opinions or other content of the Internet.
Customer agrees that it shall make no claim whatsoever against Level 3 relating
to the content of the Internet or respecting any information, product, service
or software ordered through or provided by virtue of the Internet.

10. Prior to occupancy and during the term of use of any Space, Customer shall
procure and maintain the following minimum insurance coverage: (a) Workers'
Compensation in compliance with all applicable statutes of appropriate
jurisdiction. Employer's Liability with limits of $500,000 each accident; (b)
Commercial General Liability with combined single limits of $1,000,000 each
occurrence; and (c) "All Risk" Property insurance covering all of Customers
personal property located in the Space. Customer's Commercial General Liability
policy shall be endorsed to show Level 3 (and any underlying property owner, as
requested by Level 3) as an additional insured. All policies shall provide that
Customer's insurers waive all rights of subrogation against Level 3. Customer
shall furnish Level 3 with certificates of insurance demonstrating that Customer
has obtained the required insurance coverages prior to occupancy of the Space.
Such certificates shall contain a statement that the insurance coverage shall
not be materially changed or cancelled without at least thirty (30) days prior
written notice to Level 3. Customer shall require any contractor entering the
Space on its behalf to procure and maintain the same types, amounts and coverage
extensions as required of Customer above.

11. The liability of Level 3 for damages arising out of the furnishing of
Services or the Space, including but not limited to mistakes, omissions,
interruptions, delays, tortious conduct or errors, or other defects arising out
of the failure to furnish Services or Space, whether caused by acts of
commission or omission, shall be limited to a prorated refund of the charges
paid by Customer for the use of the Space hereunder. The extension of such
refunds shall be the sole remedy of Customer and the sole liability of Level 3.

                              TERMS AND CONDITIONS
                     INTERNET ACCESS - DEDICATED AND DIAL UP

The following Terms and Conditions shall be applicable to dedicated and dial-up
Internet Access Service (the "Internet Access Services") ordered by Customer
under any Customer Order.

1. Any state or federal tariffs applicable to the Internet Access Services to be
delivered under any Customer Order are incorporated into the terms thereof. The
Internet Access Services shall at all times be used in compliance with Level 3's
then-current Acceptable Use Policy and Privacy Policy, as amended by Level 3
from time to time and which are available through Level 3's web site.

2. The nonrecurring charges and monthly recurring rates for the Internet Access
Services provided by Level 3 to Customer shall be set forth in each Customer
Order.

3. Customer hereby agrees to pay for the Internet Access Services for the period
of time specified in each Customer Order, which period shall commence with the
initiation of delivery of such Internet Access Services. The rates and other
charges set forth in each Customer Order are established in reliance on the term
and/or volume commitment made therein. In the event that Customer terminates
Internet Access Services ordered in any Customer Order or in the event that the
delivery of Internet Access Services is terminated due to a failure of Customer
to satisfy the requirements set forth herein or in the Customer Order prior to
the end of the agreed term, Customer shall (unless Customer has made a Revenue
Commitment) pay a termination charge equal to the termination or other charges
paid or to be paid by Level 3 for services purchased from other sources used to
deliver the Internet Access Services to Customer, plus the percentage of the
monthly recurring charges for the terminated Internet Access Services calculated
as follows:


a.     100% of the monthly recurring charge that would have been incurred for
the Internet Access Service for months 1-12 of the agreed term; plus

b.     75% of the monthly recurring charge that would have been incurred for
the Internet Access Service for months 13-24 of the agreed term; plus

c.     50% of the monthly recurring charge that would have been incurred for
the Internet Access Service for months 25 through the end of the agreed term.


Customer may, in the event that a Revenue Commitment is made and is then being
satisfied by Customer, terminate, rearrange or reconfigure the Internet Access
Services ordered under a Customer Order without payment of the termination
charge specified above; PROVIDED, HOWEVER, that Customer shall be responsible
for payment of Level 3's then-current standard nonrecurring charges for such
termination, rearrangement or reconfiguration.

4. Level 3 provides only access to the Internet; Level 3 does not operate or
control the information, services, opinions or other content of the Internet.
Customer agrees that it shall make no claim whatsoever against Level 3 relating
to the content of the Internet or respecting any information, product, service
or software ordered through or provided by virtue of the Internet.

5. This Section 5 shall apply only to Customers who order Dial-Up Internet
Access Services. The Dial-Up Internet Access Services shall be used only by an
officer, director, employee or agent ("Employee") of Customer. Customer shall
assure that each Employee accessing the Dial-Up Internet Access Service abides
by these Terms and Conditions. Prior to any Employee accessing Dial-Up Internet
Access Services, such Employee will be required to accurately complete an
on-line registration process. During this registration process, each Employee
will be required to identify himself/herself through some means satisfactory to
Level 3. Pursuant to the registration process, by clicking an "ACCEPT" icon,
each Employee will (i) agree to accurately complete the registration; (ii) agree
to abide by all of the provisions, terms, limitations, conditions and
restrictions of these Terms and Conditions; and (iii) agree to use the Dial-Up
Internet Access Services in accordance with any requirements set forth in the

                     Standard Service Level Agreement (SLA)
                                    Release 1
                            INTERNET DEDICATED ACCESS

Dedicated Internet Access service will be backed by a Standard Service Level
Agreement that has two components: a Service Delivery SLA and a Network
Performance SLA.

NOTE: The total number of credits per month for both Service Delivery and
Network Performance is limited to four days.

SERVICE DELIVERY SLA

- -    30 Calendar Day Installation Guarantee for Customers buying Dedicated
     Internet Access in speeds from 64 Kbps - 1.544 Kbps within the Standard
     Service Area..

- -    45 Calendar Day Installation Guarantee for Customers buying Dedicated
     Internet Access in speeds from 3 Mbps - 45 Mbps within the Standard Service
     Area.

- -    Single toll-free number to reach Level 3 Customer Service for all customer
     issues, including technical, billing, and product inquiries.

- -    Time to Respond - Within 30 minutes

- -    2 hour calendar month Average Time To Repair (ATTR)

If Level 3 fails to meet any of the guarantees above, Level 3 will review all
reported failures at the end of the month, and calculate the applicable credits:

- -    Any customer inquiry to the Level 3 Customer Service Center that results in
     a Time to Respond of >30 minutes will result in a one day service credit
     when the customer notifies Level 3 of the failure.

- -    ATTR is calculated as a monthly average. All reported customer trouble
     tickets will be totaled over the month, then the average time to close each
     ticket will be calculated. If the ATTR is greater than 2 hours, the
     customer will receive a one day service credit.

- -    Credits will only be applied to events where the Customer reports a failure
     to the Level 3 Customer Care organization. Customers must report any
     Service Delivery failures within five business days of the event.

NETWORK PERFORMANCE SLA

- -     SERVICE AVAILABILITY

      -     Availability refers to customer's access point to the Level 3
            Internet network, including their Level 3 provided local access
            circuit, and the customer's port.

      -     Unavailability Events are defined as any outage of the Level 3
            provided local access circuit and the customer's port of longer than
            15 consecutive minutes.



                                 Page 14 of 17
<PAGE>   15

      -     The Availability Guarantee does not extend to the performance of
            Internet networks controlled by other companies, or traffic exchange
            points (including NAPs and MAEs) which are controlled by other
            companies.

      -     Availability does not include regularly scheduled or emergency
            maintenance events, or customer caused outages or disruptions.

      -     Customers may report service unavailability events of longer than 15
            consecutive minutes to Level 3 customer service within 48 hours of
            the event. If the event is confirmed by Level 3 customer service,
            the customer will receive a pro-rated service credit that equals the
            time of the unavailability.

- -     40 MS ONE-WAY DELAY GUARANTEE

      -     The Delay guarantee refers to the average delay parameters among the
            Level 3 Gateway sites in the United States. It does not extend to
            the customer's local access circuit, transit or peering connections,
            or to circuits to the traffic exchange points, including NAPs and
            MAEs.

      -     Delay is measured as the average delay, over a calendar month, of
            traffic between all major Gateways on the Level 3 U.S. Internet
            network.

      -     Level 3 will publicly report the Average Monthly Delay measurement
            for the Level 3 U.S. Internet Network at the end of every month.

      -     If the customer reports that Level 3 has failed to meet the Delay
            guarantee, and this is confirmed by Level 3 customer service, the
            customer will be issued one day service credit.

NOTES:

- -     All measurements are based on monthly averages.

- -     These guarantees only apply to the Level 3 Internet Network. They do not
      apply to NAP or transit connections, or to any traffic once it leaves the
      Level 3 network.

- -     This SLA does not apply to periods of regularly scheduled or emergency
      maintenance that Level 3 performs on its network or associated hardware
      and software.

- -     Credits will only be applied to events where the Customer reports a
      network performance failure to the Level 3 Customer Care organization.

- -     Customers must report any Network Performance failures (unavailability or
      delay) within 48 hours (two business days) of the service affecting event
      in order to receive a credit. Customers must report any Service Delivery
      failures within five business days of the event.

                              TERMS AND CONDITIONS

           MANAGED MODEM -- DEDICATED, QUICKSTART AND TRANSIT SERVICES

The following Terms and Conditions shall be applicable to services required to
allow access to "Dedicated Services," "Dedicated Service with QuickStart" and
"Transit Services" as offered by Level 3 (the "Managed Modem Services") ordered
by Customer under any Customer Order.

1. Any state or federal tariffs applicable to the Managed Modem Services to be
delivered under any Customer Order are incorporated into the terms thereof. The
Managed Modem Services shall at all times be used in compliance with Level 3's
then-current Acceptable Use Policy and Privacy Policy, as amended by Level 3
from time to time and which are available through Level 3's web site.

2. In the event Customer orders "Dedicated Service," end user traffic will be
routed through and aggregated in Level 3's facility, sent to the Customer's
Premises via a dedicated circuit, and then routed to its final destination by
Customer. In the event that Customer orders "Transit Services," End User traffic
will be routed to Level 3's facility and then routed to its final destination by
Level 3 via the Internet. Dedicated Service with "QuickStart" will initially be
provisioned to the Customer in the same fashion as Transit Services, until such
time as Level 3 has provisioned the dedicated circuit to send end user traffic
from Level 3's facility to the Customer's Premises. QuickStart will then be
migrated to standard Dedicated Service. Customers ordering Dedicated Services
will be required to make a portion of the Premises available to Level 3 for the
placement of equipment necessary to provide such Dedicated Services. For
Dedicated Service, all Customer CPE as well as the private line necessary to
support this service will be ordered, installed and managed by Level 3. Any
telephone numbers assigned to Customer for the purpose of providing Managed
Modem Services hereunder shall be property of Customer; PROVIDED, however, that
Level 3 shall be obligated to release such numbers to Customer upon expiration
or termination hereof if and only if Customer is then in compliance with all of
the terms contained herein or in the Standard Terms and Conditions.

3. The nonrecurring charges and monthly recurring rates for the Managed Modem
Services provided by Level 3 to Customer shall be set forth in each Customer
Order. Level 3 will dedicate the specified number of ports to Customer in the
Level 3 facilities as identified in each Customer Order. Customer may be
responsible for additional monthly charges if Customer's use of the Managed
Modem Services requires and utilizes more ports than the number committed to and
ordered by Customer.

4. Customer hereby agrees to pay for the Services for the period of time
specified in each Customer Order, which period shall commence with the
initiation of delivery of such Managed Modem Services. The rates and other
charges set forth in each Customer Order are established in reliance on the term
commitment made therein. In the event that Customer terminates Managed Modem
Services ordered in any Customer Order or in the event that the delivery of
Managed Modem Services is terminated due to a failure of Customer to satisfy the
requirements set forth herein or in the Customer Order prior to the end of the
agreed term, Customer shall (unless Customer has made a Revenue Commitment) pay
a termination charge equal to the termination or other charges paid or to be
paid by Level 3 for services purchased from other sources used to deliver the
Managed Modem Services to Customer, plus the percentage of the monthly recurring
charges for the terminated Managed Modem Services calculated as follows:


a.    100% of the monthly recurring charge that would have been incurred for
the Managed Modem Service for months 1-12 of the agreed term; plus

b.    75% of the monthly recurring charge that would have been incurred for the
Managed Modem Service for months 13-24 of the agreed term; plus

c.    50% of the monthly recurring charge that would have been incurred for the
Managed Modem Service for months 25 through the end of the agreed term.


Customer may, in the event that a Revenue Commitment is made and is then being
satisfied by Customer, terminate, rearrange or reconfigure the Managed Modem
Services ordered under a Customer Order without payment of the termination
charge specified above; PROVIDED, HOWEVER, that Customer shall be responsible
for payment of Level 3's then-current standard nonrecurring charges for such
termination, rearrangement or reconfiguration.

5. Level 3 provides only access to the Internet; Level 3 does not operate or
control the information, services, opinions or other content of the Internet.
Customer agrees that it shall make no claim whatsoever against Level 3 relating
to the content of the Internet or respecting any information, product, service
or software ordered through or provided by virtue of the Internet.

    MCI WORLDCOM services offered under this Agreement, including, without
    limitation, revenue commitments, term, volume, product mix, functionality,
    features, credits offered, level of service and geographic breadth (a
    "Competitive Offer"), and such Competitive Offer would result in an overall
    cost savings to Customer greater than [***] over the then remaining Term of
    this Agreement when compared to the effective rates charged by MCI WORLDCOM
    hereunder, then MCI WORLDCOM agrees to either match the Competitive Offer or
    to release Customer from this Agreement. [***] If MCI WORLDCOM does not
    elect to match the Competitive Offer within sixty (60) days after it is
    presented to MCI WORLDCOM by Customer in writing (with sufficient
    documentation of the Competitive Offer), [***] whichever is earlier, and (2)
    no termination or similar charges, including without limitation early
    termination charges contained in the Tariffs, shall be owed by Customer to
    MCI WORLDCOM.

8.  Credit Allowances for Service Interruptions.

    8.1 MCI WORLDCOM will grant a credit allowance whenever an interruption
        occurs because of a failure of any component furnished by MCI WORLDCOM
        under this Agreement. An interruption period begins when Customer
        reports a service, facility or circuit to be interrupted and releases it
        for testing and repair. An interruption period ends when the service,
        facility or circuit is operative. If Customer reports a service,
        facility or circuit to be inoperative but declines to release it for
        testing and repair, it is considered to be impaired, but not
        interrupted.

                                  SCHEDULE TWO
                           MASTER TERMS AND CONDITIONS


1. Services. MCI WORLDCOM shall provide to Customer the Services described in
the Service Schedules attached to the Agreement at the applicable rates,
discounts, and other terms and conditions described in the applicable Service
Schedule. Certain Services are provided by MCI WORLDCOM to Customer pursuant to
a Tariff filed by MCI WORLDCOM in the local jurisdiction where such Service is
provided ("Tariffed Services"). This Agreement incorporates by reference the
terms of each such Tariff as they apply to such Tariffed Services. For Tariffed
Services, in the event of conflict between the terms of the applicable Tariff
and this Agreement, the order of precedence shall be: the applicable Service
Schedule, this Schedule Two, and then the applicable Tariff. For Services not
provided by MCI WORLDCOM pursuant to a Tariff, such Services shall be provided
in accordance with the terms and conditions of this Agreement. To the extent
that such terms and conditions are not provided in this Agreement, the terms and
conditions set forth in the US Tariff (as defined in Schedule Three) shall be
incorporated herein with respect to such Service if there is a US Tariffed
Service that corresponds to the non-Tariffed Service to the extent permissible
and not superseded by applicable local law and regulations. Customer is a resale
common carrier subject to the Communications Act of 1934, as amended. The
Agreement is entered into pursuant to Section 211 of the Communications Act of
1934, as amended. For non-Tariffed Services, in the event of conflict between
this Agreement and the US Tariff, the order of precedence shall be: the
applicable Service Schedule, this Schedule Two, and then the applicable US
Tariff. Notwithstanding anything in this Agreement to the contrary, MCI WORLDCOM
may adjust its rates or charges, or impose additional rates and charges, in
order to recover amounts it may be required by governmental or
quasi-governmental authorities to collect from or pay to others to support
statutory or regulatory programs during the course of this Agreement.

     1.1 Detariffing. If, prior to the expiration of the Term of this Agreement,
MCI WORLDCOM voluntarily or involuntarily, as a result of government or judicial
action, cancels, in whole or in part, any Tariff on file, where the affected
provisions prior to such cancellation applied to any service(s) MCI WORLDCOM
provides under this Agreement, then effective on such cancellation and for the
remainder of the Term, this Agreement shall consist of the following, in order
of precedence from (a) through (c):

     (a) MCI WORLDCOM Tariff provisions that remain in effect ("Effective
Tariffs"), as MCI WORLDCOM may amend from time to time in accordance with law;
and

     (b) Specific provisions contained in this Agreement that expressly apply in
lieu of, or that apply in addition to, provisions contained in Effective Tariffs
and/or in MCI WORLDCOM's standard Guide to Services and Pricing ("Price Guide");
and

     (c) Provisions contained in the Price Guide to the extent that (a) and (b)
above are not applicable. MCI WORLDCOM may amend the Price Guide from time to
time and will maintain the Price Guide open for public inspection at one or more
offices during normal business hours. Immediately prior to the cancellation of
any Tariff provisions applicable to service(s) provided under this Agreement,
MCI WORLDCOM shall incorporate such provisions into the Price Guide and if MCI
WORLDCOM fails to incorporate any such provisions, such provisions shall be
deemed incorporated into this Agreement as if MCI WORLDCOM had so incorporated
such provisions in the Price Guide.

     In all events, the applicable rates and rate schedules shall continue to be
subject to any discounts, waivers, credits, or restrictions on rate changes that
may be contained in this Agreement for Tariffed Services. Where rate and/or
discount adjustments would have been made by reference to any canceled Tariff
rate, rate schedule, discount and/or discount schedule, these adjustments shall
instead be made by reference to the Price Guide. To the extent that any
adjustment to Tariffed rates, rate schedules, discounts and/or discount
schedules is permitted under this Agreement, such adjustment may be made by MCI
WORLDCOM to its Price Guide.

     1.2 Effect of Tariffing. If, at any time during the Term, MCI WORLDCOM
tariffs any of the non-Tariffed Services provided to Customer under this
Agreement (each a "Newly Tariffed Service"), Customer agrees that the Tariff
shall govern with respect to the Newly Tariffed Service and to incorporate such
Newly Tariffed Service into the appropriate Service Schedule. Such Service
Schedule shall contain the same rates, charges, discounts, term commitment, and
volume commitment for the Newly Tariffed Service as set forth herein.

2. Payment of MCI WORLDCOM Invoices. Unless otherwise specified in an GSA
Schedule attached hereto, all amounts due for Services shall be billed in U.S.
Dollars. Customer is required to pay MCI WORLDCOM for Services, including any
applicable underutilization charges and/or early termination charges, within
thirty (30) days after the date of MCI WORLDCOM's invoice. Amounts not paid
within thirty (30) days after the date of the invoice will be considered past
due and a failure to perform a material obligation under this Agreement, and MCI
WORLDCOM may terminate this Agreement or the applicable GSA Schedule immediately
upon written notice of any sum past due or pursuant to the terms of any
applicable Tariff. Independent of such payment obligations, Customer shall make
a separate claim in writing, with adequate support, for any credit for service
interruption to which Customer believes itself entitled hereunder, and MCI
WORLDCOM and Customer will promptly address such claim. If Customer does not
give MCI WORLDCOM written notice of a dispute with respect to any charges within
six (6) months of the date an invoice was rendered, such invoice shall be deemed
to be correct and binding. Failure of MCI WORLDCOM to invoice Customer in a
timely manner for any amounts due hereunder shall not be deemed a waiver by MCI
WORLDCOM of its rights to payment therefor. Where an element of a Service is
considered to be rendered directly from a third party carrier to Customer and
where said carrier does not have a one-stop billing arrangement with MCI
WORLDCOM that allows MCI WORLDCOM to bill Customer on behalf of such third
party, Customer agrees to pay for said element directly to such third party
carrier.

3. Taxes and Access Charges.

     3.1 Domestic and International Taxes


                           MCI WORLDCOM CONFIDENTIAL

                                       1
<PAGE>   6

     (a) All charges are exclusive of federal, state, local, and foreign sales,
use, excise, utility, gross receipts, value added taxes (VAT), other similar
tax-like charges and tax-related surcharges as provided in MCI WORLDCOM's F.C.C.
and state tariffs, and other similar tax-like charges levied by any duly
constituted authority, which Customer agrees to pay.

     (b) In the event that Customer provides MCI WORLDCOM with a duly authorized
exemption certificate, MCI WORLDCOM agrees to exempt Customer from such taxes if
and as provided by applicable law, effective on the date the exemption
certificate is received by MCI WORLDCOM.

     (c) Taxes based on MCI WORLDCOM's net income shall be the sole
responsibility of MCI WORLDCOM; provided that, if Customer is required by the
laws of any foreign tax jurisdiction to withhold income or profits taxes from
any payment, Customer shall, within 90 days of the date of such withholding,
provide to MCI WORLDCOM official tax certificates documenting remittance of such
taxes to the relevant tax authorities. Such tax certificates shall be in a form
sufficient under the U.S. Internal Revenue Code to document the qualification of
such income or profits tax for the foreign tax credit allowable against MCI
WORLDCOM's U.S. corporation income tax, and shall be accompanied by an English
translation. Upon receipt of such certificates, MCI WORLDCOM will issue Customer
a billing credit for the amounts represented thereby.

     3.2 Pass-Through Charges. Unless otherwise provided for in the applicable
product description contained in a GSA Schedule, MCI WORLDCOM will pass through
to Customer, and Customer shall be solely responsible for, any charges
(including, without limitation, installation charges), fees, taxes and terms and
conditions of service imposed by domestic and international access/egress
service suppliers in relation to the provision of Services, including, but not
limited to, rate fluctuations in tariffs, communications charges and access
charges that are imposed or enacted by access suppliers after the Service
Effective Date. Customer shall be responsible for any gains or losses associated
with fluctuations in the exchange rate and/or timing of payment where access
charges are billed in non-U.S. currency and are to be paid by Customers in U.S.
Dollars.

4. Customer Obligations. In addition to the other obligations of Customer
contained in this Agreement, including, but not limited to, any specific
Customer obligations contained in a GSA Schedule, Customer shall be responsible
for the following obligations.

     4.1 Customer-Obtained Facilities. Customer is responsible for obtaining,
installing, and maintaining all equipment, software, wiring, power sources,
telephone connections and/or communications services necessary for
inter-connection with MCI WORLDCOM's network or otherwise for use in conjunction
with the applicable Services ("Facilities"). Customer is responsible for
ensuring that such Facilities are compatible with MCI WORLDCOM's requirements
and that they continue to be compatible with subsequent revision levels of MCI
WORLDCOM-provided equipment, software and services. MCI WORLDCOM is not
responsible for the availability, capacity and/or condition of any Facilities
not provided by MCI WORLDCOM. The Customer shall obtain and hereby grants to MCI
WORLDCOM all licenses, waivers, consents, or registrations necessary to deliver,
install, and keep installed at the Customer site the MCI WORLDCOM equipment.

     4.2 Security. Customer shall, at its own expense, take all reasonable
physical and information systems security measures necessary to protect all
equipment, software, data and systems located on Customer's premises or
otherwise in Customer's control and used in connection with the Services,
whether owned by Customer, MCI WORLDCOM, or MCI WORLDCOM's subcontractors.
Customer acknowledges and agrees that MCI WORLDCOM is not liable, either in
contract or in tort, for any loss resulting from any unauthorized access to or
alteration of, theft, destruction, corruption, or use of, Facilities used in
connection with the Services.

     4.3 Customer Sites. Customer agrees to provide MCI WORLDCOM and its
subcontractors and their respective employees and agents access to Customer's

as necessary for MCI WORLDCOM and its subcontractors to perform the Services.

5. Software and Documentation. Software and related documentation provided by
MCI WORLDCOM to Customer in connection with the Services and not otherwise
subject to either a separate written agreement executed between MCI WORLDCOM and
Customer or to an accompanying shrink wrap license (collectively the "Software")
is subject to the following:

     (a) In consideration for payment of any applicable fees, Customer is
granted a personal, non-exclusive, non-transferable license to use the Software,
in object code form only, solely in connection with the Services for Customer's
internal business purposes on Customer-owned or Customer-leased equipment (the
"License"). Customer shall not use the Software (i) in connection with the
products and/or services of any third party, or (ii) to provide services for the
benefit of any third party, including without limitation as a service bureau.

     (b) Customer may make one copy of the Software, other than the
documentation, for archival or back-up purposes only, provided that any
copyright and other proprietary rights notices are reproduced on such copy.
Customer shall not make any copies of documentation provided as part of the
Software.

     (c) Customer shall not: (i) attempt to reverse engineer, decompile,
disassemble or otherwise translate or modify the Software in any manner; or (ii)
sell, assign, license, sublicense or otherwise transfer, transmit or convey
Software, or any copies or modifications thereof, or any interest therein, to
any third party.

     (d) All rights in the Software, including without limitation any patents,
copyrights and any other intellectual property rights therein, shall remain the
exclusive property of MCI WORLDCOM and/or its licensors. Customer agrees that
the Software is the proprietary and confidential information of MCI WORLDCOM
and/or its licensors subject to the provisions of Section 6 ("Confidential
Information") below.

     (e) Except to the extent otherwise expressly agreed by the parties in
writing, MCI WORLDCOM has no obligation to provide maintenance or other support

     (f) The License shall immediately terminate upon the earlier of: (i)
termination or expiration of this Agreement; (ii) termination of the Service(s)
with which the Software is intended


                           MCI WORLDCOM CONFIDENTIAL

                                       2

for use; or (iii) failure of Customer to comply with any provisions of this
Section. Upon termination of any License, at MCI WORLDCOM's option, Customer
shall promptly either (i) destroy all copies of the Software in its possession,
or (ii) return all such copies to MCI WORLDCOM, and in either event provide a
written officer's certification confirming the same.

6. Confidential Information.

     6.1 Obligations. The recipient party shall protect all information received
from the disclosing party or otherwise discovered by the recipient party during
the course of this Agreement, including without limitation all information
relating to the other party's technology, research and development, business
affairs, pricing, the terms of this Agreement, or such information of the other
party that may be reasonably understood from legends, the nature of such
information itself and/or the circumstances of such information's disclosure, to
be confidential and/or proprietary to the owning party or to third parties to
which a party owes a duty of non-disclosure (collectively the "Confidential
Information") from disclosure to others, using the same degree of care used to
protect it's own proprietary information of like importance, but in any case
using no less than a reasonable degree of care, and shall further use such
Confidential Information only for the purpose of this Agreement. Confidential
Information may be disclosed in written or other tangible form (including on
magnetic media) or by oral, visual or other means. Except as otherwise provided
in Section 5 ("Software and Documentation"), the recipient party may make such
copies of Confidential Information in tangible form as are reasonably required
in connection with its use as permitted under this paragraph.

     6.2 Exceptions. The foregoing restrictions on use and disclosure of
Confidential Information do not apply to information that: (i) is publicly known
at the time of the owning party's communication thereof to the recipient party;
(ii) is, or becomes publicly known, through no fault of the recipient party
subsequent to the time of owning party's communication thereof to the recipient
party; (iii) is received by the recipient party free of any obligation of
confidence prior to the time such information is received by the recipient
party; provided however, that the recipient party immediately informs the owning
party in writing to establish the recipient party's prior possession; (iv) is
developed independently by the recipient party independently of, and without
reference to, the Confidential Information or other information of the owning
party; (v) is rightfully obtained by the recipient party from third parties
authorized to make such disclosure without restriction; or (vi) is identified in
writing by the owning party as no longer proprietary or confidential.

     6.3 Required Disclosures. In the event a party is required by law,
regulation or court order to disclose any Confidential Information, the party
required to make such disclosure will promptly notify the owning party in
writing prior to making any such disclosure in order to facilitate the owning
party seeking a protective order or other appropriate remedy from the
appropriate body. Each party agrees to cooperate with the other party in seeking
such order or other remedy. Additionally, if the owning party is not successful
in precluding the requesting legal body from requiring the disclosure of the
Confidential Information, the party required to make such disclosure will
furnish only that portion of the Confidential Information which is legally
required and will exercise all reasonable efforts to obtain reliable assurances
that confidential treatment will be accorded the Confidential Information.

     6.4 Destruction of Information. At the owning party's option, the recipient
party shall promptly either destroy all Confidential Information in tangible
form in its possession, or return all such copies to the owning party, and in
either event provide a written officer's certification confirming the same,
promptly upon the earlier of: (i) the owning party's written request; or (ii)
the expiration or earlier termination of this Agreement.

     6.5 Remedies. The parties acknowledge that Confidential Information is
unique and valuable to the owning party, and that disclosure in breach of this
Agreement will result in irreparable injury to the owning party for which
monetary damages alone would not be an adequate remedy. Therefore, Customer
agrees that in the event of a breach or threatened breach of confidentiality,
the owning party shall be entitled to specific performance and injunctive or

7. Termination.

     7.1 Discontinuation of Business. Either party may terminate this Agreement
immediately upon written notice to the other party if such other party
dissolves, discontinues or terminates its business operations to which this
Agreement pertains or such other party makes any assignment for the benefit of
creditors.

     7.2 Termination by MCI WORLDCOM. MCI WORLDCOM may terminate this Agreement
(or the applicable portion thereof) immediately upon notice to Customer if (a)
MCI WORLDCOM is unable to obtain or maintain any U.S. or foreign governmental
license, waiver, consent, registration or approval needed to provide any
facility or Service hereunder; (b) the continued provision of a facility or
Service would contravene any local, state, national, foreign or international

Service is necessary to prevent or protect against fraud or otherwise protect
MCI WORLDCOM's personnel, agents, facilities, or services; (d) MCI WORLDCOM is
unable to continue to provide a third-party subcontractor's, vendor's or
interconnected carrier's facility, component of equipment, or service for any
reason, provided, however, that where such third party has ceased to provide any
facility, equipment, or service, MCI WORLDCOM will exercise commercially
reasonable efforts to continue to provide to Customer a comparable facility,
equipment, or service by or through another vendor under comparable terms and
conditions; (e) MCI WORLDCOM discovers that Customer provided false information
to MCI WORLDCOM regarding Customer's identity, credit-worthiness, or its planned

within thirty (30) days of Customer's receipt of written notice thereof; or (g)

     7.4 Customer's Termination Liability. If (a) Customer terminates this
Agreement during the Term, for reasons other than to take service under another
arrangement with MCI WORLDCOM having equal or greater term and volume
requirements; or (b) MCI WORLDCOM terminates this Agreement in accordance with
Sections 7.2(f) or (g), then Customer will pay termination charges in accordance
with Schedule One. If Customer terminates a Service Schedule other than in
accordance with that Schedule; or (b) MCI WORLDCOM terminates a Service Schedule
in accordance with that Schedule, then Customer will pay termination charges in
accordance with the applicable Schedule.

     7.5 Service Orders. Customer shall request the delivery of dedicated local
access services by executing a service order in form and substance satisfactory
to MCI WORLDCOM (the "Service Order"). The Service Order sets forth the place of
delivery, circuit contracted term, pricing and other details. All Service Orders
are subject to the terms and conditions of this Agreement. A separate Service
Order must be completed for each circuit ordered. Customer will be responsible
for payment of the rates and charges for the contracted term, as set forth in
each Service Order. Each Service Order shall survive the termination or
expiration of this Agreement; provided, however, that MCI WORLDCOM may terminate
one or more Service Orders if MCI WORLDCOM terminates this Agreement pursuant to
Section 7 hereof. If Customer terminates a Service Order prior to the end of six
(6) months (the "Minimum Installation Period") for reasons other than for
"Cause" (as defined in Section 6 of Schedule One) or if MCI WORLDCOM terminates
a Service Order for Cause prior to the Minimum Installation Period for any
circuit, then Customer will pay within thirty (30) days after such termination:
the monthly recurring charge for such circuit(s) multiplied by six (6) minus the
monthly recurring charge for such circuit multiplied by the number of months
installed. Notwithstanding a termination of a Service Order, the Agreement and
other Service Orders will remain in full force and effect unless expressly
terminated as permitted by this Agreement.

8. Indemnification. Each party agrees to defend, at its own expense, and
indemnify and hold harmless the other party and its subcontractors (collectively

personal property, death or bodily harm, brought by a third party and asserted
against or incurred by any of the Indemnitees arising out of or relating to: (a)
either party's acts, omissions and/or breach of its obligations under this
Agreement. In addition, Customer agrees to defend, at its own expense, and
indemnify and hold harmless MCI WORLDCOM and its Indemnities from and against
any claims, suits, damages and expenses asserted by a third party against or
incurred by any of the MCI WORLDCOM Indemnities arising out of or relating to:
(a) use of any Services or related products and documentation provided to
Customer hereunder; (b) Customer's connection of any MCI WORLDCOM product or
service to any third party service or network, including without limitation,
damages resulting from unauthorized use of, or access to, MCI WORLDCOM's
network, (c) the violation of any FCC or other applicable international,
federal, state or local law or regulation by Customer; and (d) the accuracy of

                                       4

local license or permit requirements, (ii) export, import and customs laws and
regulations (such as the export and re-export controls under the U.S. Export
Administration Regulations and/or similar regulations of the U.S. or any other
country) which may apply to certain equipment, software and technical data
provided hereunder, and (iii) foreign corrupt practices acts. Notwithstanding
the foregoing, MCI WORLDCOM does not represent that any necessary import, export
or customs licenses or approvals will be granted with respect to Services
provided hereunder.

11. Resale of MCI WORLDCOM Services.

     11.1 In reselling Services under this Agreement, Customer agrees to sell
and bill its own services under Customer's own name, identity or mark, and
Customer further agrees not to reference MCI WORLDCOM name or marks in any
context involving Customer's furnishing of services to the public. In addition
to other applicable remedies, MCI WORLDCOM shall be entitled to seek injunctive
relief with respect to any violation of this Paragraph 11. Any opportunity to
cure a breach of this Paragraph shall be subject to MCI WORLDCOM's reasonable
satisfaction as to the curability of the original injury caused by such breach
and the effectiveness of any attempted cure. MCI WORLDCOM's right to enforce
this Paragraph as a material provision of this Agreement shall not in any manner
require a showing of financial, legal or other loss or injury to MCI WORLDCOM of
any kind

     11.2 Customer agrees that it will obtain and maintain any and all approvals
to resell the Services hereunder from the FCC, including requirements imposed by
Section 214 of the Communications Act of 1934, as amended, and state regulatory
bodies. In the event Customer fails to obtain or maintain the appropriate
approvals, MCI WORLDCOM shall not be liable for any suspension of service or
other delay or failure to provide the Services.

     11.3 Customer shall have sole responsibility for interacting with its
customers in all matters pertaining to service, including the placing and
handling of service orders, service installation, operation and termination,
dispute handling and resolution, and billing and collection matters. MCI
WORLDCOM shall incur no obligation, nor shall it be deemed to have any
obligation, to interact with Customer's customers and end users ("End Users")
for any reason or purpose. Customer shall cooperate with MCI WORLDCOM as
necessary to address and resolve service-related issues and problems and shall
impose upon its customers an obligation to cooperate with Customer in addressing
and resolving service-related issues and problems.

     11.4 Customer understands and accepts that, as part of MCI WORLDCOM's
normal business policy and practices and its obligations under law, MCI WORLDCOM
will engage in extensive marketing efforts in an attempt to sell its services to
the public and that such efforts will result in active competition with Customer
for the business of users who are Customer's End Users or prospects, provided
MCI WORLDCOM will not use Confidential Information to actively compete with
Customer. Under no circumstance shall any inference be derived that MCI
WORLDCOM's entry into this Agreement with Customer means that MCI WORLDCOM will
restrict its efforts to compete against Customer in any way.

     11.5 Customer understands and accepts that no fiduciary relationship arises
by virtue of this Agreement and that, accordingly, MCI WORLDCOM incurs none of
the obligations that arise in such relationship as an incident of its fulfilling
its obligations under this Agreement. Further, Customer understands and accepts
that MCI WORLDCOM neither insures the profits for Customer nor guarantees the
success of Customer's business as a result of Customer's receipt of Services
under this Agreement.

        percent (25%). For Metro Private Line Service (Type 2) for DS-3
        circuits, Customer will pay a monthly recurring charge per circuit equal
        to the greater of: (i) [***] rate for such circuit or (ii) the offnet

    (POP). Customer will execute a Letter of Agency authorizing MCI WorldCom to
    interact directly with the provider(s) of these access telecommunications
    facilities on behalf of Customer. When MCI WorldCom acts as Customer's
    agent, Customer is responsible for charges, including without limitation,
    monthly charges, usage charges, installation charges, non-recurring charges,
    or applicable termination/cancellation liabilities, of the provider(s) of
    Local Loop facilities to MCI WorldCom's POP. In obtaining Local Loop
    Facilities on behalf of the Customer, MCI WorldCom shall be responsible for
    provisioning and the initial testing of an interconnection (reasonably
    coordinated with the in-service date) between such inter-exchange service
    set forth in the order and a designated Customer termination point ("Local
    Access"). [***]

3.  SERVICE MIGRATION. In the event Customer has multiple DS-1's, DS-3's, OC-3's
    or OC-12's between the same two city pairs, Customer has the option of
    ordering a larger level of service (e.g., DS-3, OC-3, OC-12, or OC-48), and
    migrate the existing circuits onto the larger bandwidth. Customer agrees to
    pay for the entire amount of the larger bandwidth at the time of
    installation of the new order. [***]

1  Connectivity is provided to Customer's organization only. Resale to or use by
   persons or entities outside of Customer's organization is prohibited. UUNET
   may suspend the service or terminate this Schedule effective upon notice for
   a violation of this prohibition.

   will charge an additional $500 fee.

3  With T1 Burstable service, Customer receives full T1 access to UUNET and can
   burst to the full 1.5 Mbps at any time. Monthly billing is based on the level
   of sustained use during the month, as determined by traffic samples taken
   every five minutes. The level under which 95% of the samples fall is the
   sustained use. Customer may move to a lower burstable service level if the
   sustained use is at or below such burstable service level for at least two
   consecutive months and Customer thereafter notifies UUNET in writing of its
   intent to move to such lower burstable service level.

   Commitment, this Schedule shall continue in effect on a month-to-month basis
   at UUNET's then-current list price for the service.

7  UUNET is acting only as a reseller with respect to the hardware and software
   offered under this Schedule ("Equipment"), which was manufactured by a third
   party ("Manufacturer"). UUNET will provide first -level support for
   Equipment, but will not repair or replace Equipment. Customer's use of the
   Equipment is subject to the terms and conditions of the Manufacturer's end
   user agreement. Should Customer purchase Equipment from UUNET, UUNET will
   ship the current UUNET-tested version of the Equipment to the Customer.

    penalty by providing UUNET written notice of termination during the 30 days
    following notice of such amendment. The SLA sets forth Customer's sole
    remedies for any claim relating to this service or the UUNET Network,

    company line charge which, absent the credit, would have been charged for
    such month.

8.  Neither party may use the other party's name, trademarks, tradenames or
    other proprietary identifying symbols without the prior written approval of
    the other party. Neither party may assign or transfer any of its rights or
    obligations under this Schedule without the express, prior written consent
    of the other party; provided, that either party may assign or transfer this
    Schedule to any affiliate of such party upon advance written notice to the
    other party. No failure on the part of either party to exercise, and no
    delay in exercising, any right or remedy hereunder shall operate as a waiver
    thereof nor shall any single or partial exercise of any right or remedy

    hereunder preclude any other or further exercise thereof or the exercise of
    any other right or remedy granted hereby or by law.

9.  MCI WORLDCOM, Inc. or its affiliates or subcontractors may perform some or
    all of UUNET's duties and/or obligations hereunder.

10. This Schedule is in addition to and subject to the GSA. To the extent this
    Schedule conflicts with any provision of the GSA, this Schedule shall
    prevail. Activation of service shall indicate UUNET's acceptance of this
    Schedule. Use of the UUNET Network constitutes acceptance of this Schedule.

TERM COMMITMENT(5) Unless a different term is selected below, the term of this
Schedule will be coterminous with the Global Service Agreement as currently in

Customer shall receive a [***] off its monthly recurring charges on ports only.

                   PLEASE SIGN THIS SCHEDULE ON THE NEXT PAGE.


- --------

1 Customer must provide 60 days' prior written notice to UUNET before
  downgrading service to a lower tier. While Customer can resell Internet
  connectivity, Customer cannot resell the service in its entirety to another
  person or entity without the express prior written consent of UUNET. If
  Customer resells Internet connectivity to end users, Customer is responsible
  for: (i) providing the first point of contact for end user support inquiries;
  (ii) providing software fulfillment to end users; (iii) running its own
  primary and secondary domain name service ("DNS") for end users; (iv)
  registering end users' domain names; (v) using BGP routing to the UUNET
  Network, if requested by UUNET; (vi) collecting route additions and changes,
  and providing them to UUNET; and (vii) registering with the appropriate agency
  all IP addresses provided by UUNET to Customer that are allocated to end
  users.

2 To ensure proper installation, UUNET will order all telco lines. A $500
  surcharge applies to Customer-ordered lines. Installation may be scheduled
  between the hours of 8AM and 7PM ET Monday through Friday (excluding
  holidays). If Customer requires installation outside of these hours UUNET will
  charge an additional $500 fee.

3 UUNET is acting only as a reseller with respect to the hardware and software
  offered under this Schedule ("Equipment"), which was manufactured by a third
  party ("Manufacturer"). UUNET will provide first level support for Equipment,
  but will not repair or replace Equipment. Customer's use of the Equipment is
  subject to the terms and conditions of the Manufacturer's end user agreement.
  Should Customer purchase Equipment from UUNET, UUNET will ship the current
  UUNET-tested version of the Equipment to the Customer.

4 Descriptions of the domain name, mail, news services, and other network
  applications available in connection with this service, and the pricing and
  additional terms applicable to these services, are set forth in the Network
  Applications Fee Schedule available at www.uu.net/terms. UUNET reserves the
  right to change the Network Applications Fee Schedule from time to time,
  effective upon posting of the changes to that URL or other notice to Customer.

5 Discount applicable only to Monthly Fee. At the conclusion of the Term
  Commitment, this Schedule shall continue in effect on a month-to-month basis
  at UUNET's then-current list price for the service.

                         ADDITIONAL TERMS AND CONDITIONS

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

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

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

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

5.  Payment terms shall be as set forth in the GSA. Fees paid by Customer under
    this Agreement for UUNET services will count towards Customer's Annual
    Minimum under its existing MCI WorldCom GSA. The amount to be applied will
    be that actually paid by Customer, net of any discounts or applicable
    credits, and excluding any amount paid for taxes or tax-like surcharges or
    fees.

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

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

8.  Neither party may use the other party's name, trademarks, tradenames or
    other proprietary identifying symbols without the prior written approval of
    the other party. Neither party may assign or transfer any of its rights or
    obligations under this Schedule without the express, prior written consent
    of the other party; provided, that either party may assign or transfer this
    Schedule to any affiliate of such party upon advance written notice to the
    other party. No failure on the part of either party to exercise, and no
    delay in exercising, any right or remedy hereunder shall operate as a waiver
    thereof nor shall any single or partial exercise of any right or remedy





<PAGE>   24


    hereunder preclude any other or further exercise thereof or the exercise of
    any other right or remedy granted hereby or by law.

9. MCI WORLDCOM, Inc. or its affiliates or subcontractors may perform some or
   all of UUNET's duties and/or obligations hereunder.

10. This Schedule is in addition to and subject to the GSA. To the extent this
    Schedule conflicts with any provision of the GSA, this Schedule shall
    prevail. Activation of service shall indicate UUNET's acceptance of this
    Schedule. Use of the UUNET Network constitutes acceptance of this Schedule.

                MASTER CARRIER AGREEMENT - TERMS AND CONDITIONS           Page 1


1. PROVISION OF SERVICES. CUSTOMER hereby orders and AT&T hereby agrees to
provide the AT&T services described in the Attachment(s) to this Agreement (the
"Services"). Jurisdictionally intrastate services may be provided pursuant to an
Attachment to this Agreement, pursuant to applicable state tariffs, or as
otherwise permitted by applicable state law. AT&T is not responsible for the
quality of transmission or signaling on CUSTOMER's side of the network interface
between AT&T and CUSTOMER. Service is furnished subject to the availability of
the service components required, and subject to operational and systems
constraints.

2. BILLING AND PAYMENT FOR THE SERVICES. Except as may be provided in an
Attachment, AT&T will send a single monthly bill for each of the Services to one
location designated by CUSTOMER. CUSTOMER is liable for all amounts due to AT&T
under this Agreement. Payment is due upon presentation of a bill. Payment will
be considered timely if made to AT&T within thirty days after the bill date (for
voice services, the bill date is the day after the end of the usage period
covered by the bill; for data services, the bill date is the first day of the
service period covered by the bill). Any charges not paid to AT&T within such
period will be considered past due.

3. NON-PAYMENT. At AT&T's option, interest charges may be added to any past due
amounts at the lower of 12.0% per year or the maximum rate allowed by law.
CUSTOMER shall reimburse AT&T for reasonable attorney's fees and any other costs
associated with collecting delinquent or dishonored payments. Restrictive
endorsements or other statements on checks accepted by AT&T will not apply.

4. BILLING DISPUTES. If CUSTOMER wishes to dispute a charge on a bill, CUSTOMER
must identify the specific charge in dispute and provide a full written
explanation of the basis for the dispute using a standard AT&T billing dispute
form within 90 days after the bill date. CUSTOMER may withhold payment of a
charge subject to a good faith dispute provided: (a) CUSTOMER submits the
billing dispute, using a standard AT&T billing dispute form, before making
payment of the disputed charge; (b) CUSTOMER pays the undisputed portion of all
charges; and (c) CUSTOMER cooperates reasonably with AT&T's efforts to
investigate and resolve the dispute. If AT&T determines that a disputed charge
was billed in error, AT&T shall issue a credit to reverse the amount incorrectly
billed. If AT&T determines that a disputed charge was billed correctly, payment
shall be due from CUSTOMER within five days after AT&T advises CUSTOMER in
writing that the dispute is denied.

5. DEPOSITS. Using its Deposit standards, AT&T has assessed and CUSTOMER shall
pay the Initial Deposit amount specified on the Cover Sheet before Services are
provided. AT&T may require CUSTOMER, during the term of this Agreement, to
tender a deposit in an amount to be determined by AT&T in its reasonable
discretion. AT&T will rely upon commercially reasonable factors to determine the
need for and amount of any deposit. These factors may include, but are not
limited to, payment history, number of years in business, history of service
with AT&T, bankruptcy history, current account treatment status, financial
statement analysis, and commercial credit bureau rating, as well as commitment
levels and anticipated monthly charges. Any deposit will be held by AT&T as a
guarantee for the payment of charges (including but not limited to potential
shortfall charges). A deposit does not relieve CUSTOMER of the responsibility
for the prompt payment of bills. Interest (at the rate of 6% per year) will be
paid to CUSTOMER for any period that a cash deposit is held by AT&T. A failure
of CUSTOMER to post a deposit as required by AT&T pursuant to this paragraph
shall constitute a material breach of this Agreement by CUSTOMER.

6. OBLIGATIONS REGARDING TAXES. CUSTOMER shall pay any applicable local, state
and federal taxes, levied upon the sale, installation, use or provision of the
Services, except to the extent customer provides a valid tax exemption
certificate to AT&T prior to the delivery of Services. Gross Receipts Taxes will
be charged to CUSTOMER as provided in AT&T Tariff F.C.C. No. 1, Section 2.5.14,
as amended from time to time.

7. CUSTOMER IS A CARRIER. CUSTOMER certifies it is a "common carrier" as defined
in the Communications Act of 1934 (see sections 153(10) and 211), with all
required state and federal operating authority.

8. RESPONSIBILITIES OF CUSTOMER. CUSTOMER is responsible for interfacing and
communicating with its End Users, for placing any orders, and for assuring that
it and its Intermediate Resellers (if any) comply with the provisions of this
Agreement and with all applicable federal and state laws and regulatory
requirements with respect to the resale of Services provided under this
Agreement. CUSTOMER is responsible for arranging premises access at any
reasonable time so that AT&T personnel may install, repair, maintain, inspect or
remove service components.

9. ABUSE OF SERVICE. The abuse of Service is prohibited. Using Service or
permitting Service to be used in the following ways constitutes abuse: (a)
making calls that might reasonably be expected to frighten, abuse, torment, or
harass another; (b) carrying calls that originate on the network of a
facilities-based interexchange carrier other than AT&T and terminate
disproportionately to domestic locations for which AT&T's cost of terminating
switched access (based on the published access rates of the incumbent local
exchange companies) is above AT&T's price for the call under this Agreement
(after application of discounts); (c) interfering unreasonably with the use of
AT&T service by others or the operation of the AT&T network; (d) subjecting AT&T

Not for Publication - All Rights Reserved

                MASTER CARRIER AGREEMENT - TERMS AND CONDITIONS           Page 2


personnel or non-AT&T personnel to hazardous conditions; (e) transmitting any
message or code, locating a person, or otherwise giving or obtaining
information, without payment for the Services; or (f) attempting to avoid the
payment, in whole or in part, of any charges by any means or device (non-payment
of billed charges will not be considered abuse of service for purposes of this
Section). In any instance in which AT&T believes in good faith that there is
abuse of Service as set forth above, AT&T may immediately restrict, suspend or
discontinue providing Service, without liability on the part of AT&T, and then
notify CUSTOMER of the action that AT&T has taken and the reason for such
action. To the extent doing so does not interfere with its ability to prevent
abuse of Service (to be determined in AT&T's reasonable judgment), AT&T will
attempt to limit any restriction, suspension or discontinuance under this
Section to the locations, phone numbers, or Services with respect to which the
abuse is taking place.

10. DEFAULT. If a party breaches any material term of this Agreement and the
breach continues unremedied for 60 days after written notice of default, the
other party may terminate for cause any Attachment materially affected by the
breach. If CUSTOMER is in breach of its payment obligations (including failure
to pay a required deposit), and fails to make payment in full within 5 days
after receipt of written notice of default, AT&T may, at its option, terminate
the Agreement, terminate affected Attachments, suspend Service under the
affected Attachments, and/or require a deposit, advanced payment, or other
satisfactory assurances in connection with any or all Attachments as a condition
of continuing to provide Services; except that AT&T will not take any such
action as a result of CUSTOMER's non-payment of a charge subject to a timely
billing dispute, unless AT&T has reviewed the dispute and determined that the
charge is correct. An Attachment may be terminated by either party immediately
upon written notice if the other party has become insolvent or involved in a
liquidation or termination of its business, or adjudicated bankrupt, or been
involved in an assignment for the benefit of its creditors. CUSTOMER shall be
liable to AT&T for Termination Charges, as specified in a terminated Attachment,
in the event that AT&T terminates an Attachment as a result of a breach by
CUSTOMER. Termination by either party of an Attachment does not waive any other
rights or remedies it may have under this Agreement.

11. NO WARRANTIES. AT&T MAKES NO WARRANTIES, EXPRESS OR IMPLIED, UNDER THIS
AGREEMENT AND SPECIFICALLY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR FITNESS
FOR A PARTICULAR PURPOSE. AT&T DOES NOT WARRANT THAT THE SERVICES WILL BE
UNINTERRUPTED OR ERROR-FREE, OR THAT THE SERVICES WILL MEET CUSTOMER'S
REQUIREMENTS OR THAT THE SERVICES WILL PREVENT UNAUTHORIZED ACCESS BY THIRD
PARTIES. AT&T DOES NOT AUTHORIZE ANYONE TO MAKE A WARRANTY OF ANY KIND ON ITS
BEHALF AND CUSTOMER SHOULD NOT RELY ON ANYONE MAKING SUCH STATEMENTS.

12. LIMITATION OF LIABILITY. THE LIABILITY OF AT&T ASSOCIATED WITH THE
INSTALLATION, PROVISION, USE, MAINTENANCE, REPAIR, TERMINATION OR RESTORATION OF
SERVICE PROVIDED PURSUANT TO THIS AGREEMENT SHALL NOT EXCEED AN AMOUNT EQUAL TO
THE INITIAL PERIOD CHARGE FOR AFFECTED CALLS (FOR CALLS SUBJECT TO MEASURED
CHARGES) OR THE CHARGES FOR AFFECTED SERVICE FOR THE PERIOD DURING WHICH THAT
SERVICE WAS AFFECTED (FOR ALL OTHER SERVICES). IN NO EVENT SHALL AT&T BE LIABLE
FOR: (A) ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, RELIANCE OR SPECIAL
DAMAGES, INCLUDING WITHOUT LIMITATION DAMAGES FOR LOST PROFITS, ADVANTAGE,
SAVINGS OR REVENUES OF ANY KIND, OR INCREASED COST OF OPERATIONS, WHETHER OR NOT
AT&T HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; OR (B) ANY CLAIM OR
DAMAGES CAUSED BY OR ARISING OUT OF (i) ANY ACT OR OMISSION (INCLUDING WITHOUT
LIMITATION UNAUTHORIZED USE, THEFT, OR ALTERATION OF SERVICE, OR INTERFERENCE
WITH SERVICE) BY CUSTOMER, AN INTERMEDIATE RESELLER, AN END USER, OR ANOTHER
THIRD PARTY, (ii) SERVICE INTERRUPTIONS, OR (iii) INTEROPERABILITY, INTERACTION
OR INTERCONNECTION OF THE SERVICES PROVIDED UNDER THIS AGREEMENT WITH
APPLICATIONS, EQUIPMENT, SERVICES OR NETWORKS PROVIDED BY CUSTOMER OR THIRD
PARTIES. THE LIMITATIONS OF LIABILITY SET FORTH IN THIS AGREEMENT SHALL SURVIVE
FAILURE OF AN EXCLUSIVE REMEDY, AND SHALL APPLY REGARDLESS OF THE FORM OF
ACTION, WHETHER IN CONTRACT, TORT, WARRANTY, STRICT LIABILITY, OR NEGLIGENCE
(INCLUDING WITHOUT LIMITATION ACTIVE AND PASSIVE NEGLIGENCE).

13. FORCE MAJEURE. Neither party nor its Affiliates, subsidiaries, or
subcontractors shall be liable to the other party for any delay, failure in
performance, loss or damage due to force majeure conditions such as fire,
explosion, power blackout, earthquake, volcanic action, flood, hurricane, the
elements, strike, embargo, labor disputes, civil or military authority, war,
acts of God, acts or omissions of other carriers (except, for CUSTOMER, the acts
of omissions of its Intermediate Resellers), acts of regulatory or governmental
agencies, or other causes beyond their reasonable control, except that
CUSTOMER's obligation to pay for services provided

                MASTER CARRIER AGREEMENT - TERMS AND CONDITIONS           Page 3


shall not be excused. Changes in economic, business or competitive conditions
are not force majeure conditions. If CUSTOMER is unable to meet its commitments
as a direct result of a force majeure condition, CUSTOMER may suspend its
commitments for one full billing month (or longer, with AT&T's written consent,
which shall not be unreasonably withheld). The effect of such a suspension of
commitment will be to exclude the affected month(s) from all calculations
affecting the CUSTOMER's commitments and to extend the term of this Agreement by
the same number of months. CUSTOMER must provide notice to AT&T of the force
majeure condition giving rise to the right to suspend commitments within 30 days
after its occurrence.

14. INDEMNIFICATION. CUSTOMER shall indemnify, defend, and hold harmless AT&T
and its directors, officers, employees, agents, subsidiaries, affiliates,
successors and assigns from any and all claims, damages and expenses whatsoever
(including reasonable attorneys' fees) arising on account of or in connection
with CUSTOMER's use, resale or sharing of the Services provided under this
Agreement, including but not limited to: (a) claims for libel, slander, invasion
of privacy; (b) claims for infringement of copyright arising from any
communication; (c) claims arising from any failure, breakdown, interruption or
deterioration of service provided by AT&T to CUSTOMER or by CUSTOMER to End
Users or Intermediate Resellers; (d) claims arising from CUSTOMER's marketing
efforts, including but not limited to CUSTOMER's violation of laws and
regulations applicable to the authorization and proof of authorization necessary
to convert an End User to CUSTOMER's service; and (e) claims of patent
infringement arising from combining or using services or equipment furnished by
AT&T in connection with services or equipment furnished by others. AT&T shall
indemnify, defend, and hold harmless CUSTOMER and its directors, officers,
employees, agents, subsidiaries, affiliates, successors, and assigns from all
claims of patent infringement arising solely from the use of the Services.
CUSTOMER's indemnification obligations do not apply to claims for damages to
real or tangible personal property or for bodily injury or death negligently
caused by AT&T.

15. USE OF MARKS. Nothing in this Agreement creates in a party any rights in the
other party's trade names, trademarks, service marks or any other intellectual
property. Either party may use the other party's trade names, trademarks, or
service marks only to the extent such use is not prohibited by this Agreement
and is otherwise permitted by law (including but not limited to the Lanham Act).
In no event shall either party use or display, in advertising or otherwise, any
of the other party's logos, trade dress, trade devices or other indicia of
origin, or any confusingly similar logos, trade dress, trade devices or indicia
of origin. CUSTOMER will not conduct business under any AT&T corporate or trade
name, trademark, service mark, logo, trade dress, trade device, indicia of
origin or other symbol that serves to identify and distinguish AT&T from its
competitors, or under any confusingly similar corporate or trade name,
trademark, service mark, logo, trade dress, trade device, indicia of origin or
other symbol. CUSTOMER will not indicate or imply to any other party that
CUSTOMER is affiliated with AT&T, that CUSTOMER is authorized by AT&T to sell or
provide service to them, that CUSTOMER is providing (or will provide) service to
such party jointly or in collaboration or partnership with AT&T, or as the agent
of AT&T, or that service provided by CUSTOMER or another carrier is provided by
AT&T. Except to the limited extent (if any) as may be required under law,
neither CUSTOMER nor an Intermediate Reseller shall indicate or imply to any
existing or potential End User (or Intermediate Reseller) that any portion of
the service provided to the End User (or Intermediate Reseller) by CUSTOMER or
the Intermediate Reseller is provided by AT&T or is carried over the AT&T
network or AT&T facilities.

16. RELATIONSHIP OF THE PARTIES. The relationship between the parties shall be
that of independent contractors and not of principal and agent, employer and
employee, franchiser and franchisee, partners or joint venturers. This Agreement
does not establish CUSTOMER as a dealer, distributor or franchisee of AT&T, and
no fee is being paid to AT&T to enter into this Agreement.

17. ACKNOWLEDGMENT OF RIGHT TO COMPETE. Each party acknowledges that nothing in
this Agreement diminishes or restricts in any way the rights of the parties to
engage in competition with each other. Each party acknowledges that it remains
at all times solely responsible for the success and profits of its own business.

18. USE OF MARKETING INFORMATION. Either party may use for its own marketing
purposes any and all information that it lawfully obtains from sources other
than the other party, including but not limited to information that either party
may have as a result of the sale by that party of telecommunications services or
equipment to End Users.

19. CONFIDENTIAL INFORMATION DEFINED. "Confidential Information" consists of the
following: all information disclosed by one party or its agent or representative
(the "Disclosing Party") to the other party or its agent or representative (the
"Receiving Party") in connection with this Agreement regarding the
telecommunications needs of CUSTOMER and/or the telecommunications offerings of
AT&T, to the extent that (a) for information disclosed in written, graphic or
other tangible form, it is designated by appropriate markings to be confidential
or proprietary or (b) for information disclosed orally, it is both identified as
proprietary or confidential at the time of disclosure and

                MASTER CARRIER AGREEMENT - TERMS AND CONDITIONS           Page 4


summarized in a writing so marked within 15 business days following the oral
disclosure. Notwithstanding the foregoing, all written or oral pricing,
contract, and tariff proposals exchanged between the parties shall be
Confidential Information, whether or not so designated. Confidential Information
is the property of the Disclosing Party and shall be returned to the Disclosing
Party upon request. This Agreement is Confidential Information as to which each
party is both a Disclosing Party and a Receiving Party. Information made known
to the public by the Disclosing Party or a third party, or previously known to
the Receiving Party free of any obligation to keep it confidential, or
independently developed by the Receiving Party, shall not be Confidential
Information.

20. CONFIDENTIALITY OBLIGATIONS. A Receiving Party shall hold all Confidential
Information in confidence from the time of disclosure until at least 2 years
following the termination of this Agreement. During that period, the Receiving
Party: (a) shall use such Confidential Information only for the purposes of
performing this Agreement and using the Services; (b) shall reproduce such
Confidential Information only to the extent necessary for such purposes; (c)
shall restrict disclosure of such Confidential Information to employees that
have a need to know for such purposes; (d) shall advise those employees of the
obligations of this Agreement; (e) shall not disclose Confidential Information
to any third party without prior written approval of the Disclosing Party except
as expressly provided in this Agreement; and (f) shall use at least the same
degree of care (in no-event less than reasonable care) as it uses with regard to
its own proprietary or confidential information to prevent the disclosure,
unauthorized use or publication of Confidential Information.

21. PUBLICITY. No public statements or announcements relating to this Agreement
shall be issued by either party without the prior written consent of the other
party.

22. ALTERNATIVE DISPUTE RESOLUTION. The parties will attempt to settle any claim
for non-payment of charges or recovery of overpayment of charges for the
Services provided under this Agreement (hereinafter a "Billing Dispute"),
through good faith negotiations. The parties may agree to submit a Billing
Dispute to non-binding mediation. At any time, the party seeking payment may
submit a notice of arbitration of a Billing Dispute for arbitration under the
United States Arbitration Act pursuant to the terms of this Section and the
Non-Administered Arbitration Rules of the CPR Institute for Dispute Resolution
("CPR"), to the extent such rules do not conflict. The Arbitration will be held
in New York, New York, or any other location selected by mutual agreement of the
parties. The arbitrator shall not have the power to award any damages in excess
of the limits set forth in or excluded under the limitations of liability
provided in this Agreement. The arbitrator may not limit, expand or otherwise
modify the terms of this Agreement. The arbitrator shall strictly limit
discovery to the production of documents directly relevant to the facts alleged
in the notices of arbitration and defense. If depositions are required, the
arbitrator shall permit each Party to conduct an equal number of depositions
(not to exceed five per side), with equal limits on the number of deposition
hours for each Party (not to exceed 7 per deposition). If an evidentiary hearing
is held, each Party's presentation of its case shall be limited to three (3)
days. Requests for temporary injunctive relief may be submitted to a court of
competent jurisdiction if the arbitrator has not yet been appointed, but the
arbitrator shall have the authority to modify any injunctive relief granted by
such a court. The arbitration award shall be made final within eight months of
filing of the notice of arbitration and judgment upon the award may be entered
in any court having competent jurisdiction. All participants and the arbitrator
shall hold the existence, content and results of mediation and arbitration in
confidence, except as necessary to enforce a final settlement agreement or to
enforce an arbitration award. Each party shall bear its own expenses and equally
share expenses related to the compensation of the arbitrator. The arbitrator's
award shall be in writing and shall state the reasons for the award.

23. TIME TO BRING CLAIMS. Any initial demand for arbitration pursuant to this
Agreement, and any legal action arising under this Agreement, must be initiated
within two years after the cause of action arises.

24. NOTICES. All notices under this Agreement shall be in writing and shall be
made: (a) by personal delivery; (b) by certified or registered mail, postage
prepaid return receipt requested, (c) by overnight delivery, or (d) by facsimile
transmission. Notice shall be sent to the individuals identified on the Cover
Sheet (at the address and/or fax number designated for notice), or to such other
individual, address or fax number as a party may designate by notice to the
other party.

25. EQUIPMENT. AT&T shall retain title to all of its equipment and facilities
used to provide service under this Agreement. CUSTOMER is liable to AT&T for the
replacement cost of any AT&T-provided equipment installed at CUSTOMER's premises
in the event of loss of said equipment for any reason, including but not limited
to theft.

26. EXPORT REGULATIONS. The parties acknowledge that any products, software, and
technical information (including, but not limited to, services and training)
provided under this Agreement are subject to U.S. export laws and regulations
and any use of or transfer of such products, software and technical information
must be authorized under those regulations. CUSTOMER agrees that it will not use
distribute, transfer or transmit the products, software or technical information
(even if incorporated into other products) except in compliance

                MASTER CARRIER AGREEMENT - TERMS AND CONDITIONS           Page 5


with U.S. export regulations. If requested by AT&T, CUSTOMER also agrees to sign
written assurances and other export-related documents as may be required for
AT&T to comply with U.S. export regulations.

27. QUALITY MONITORING. CUSTOMER authorizes AT&T to monitor and record calls to
AT&T concerning the Services for training and quality control purposes.

28. ASSIGNMENT. This Agreement may not be assigned by either party except that
either party may assign its rights or delegate its duties under this Agreement
to an Affiliate of that party.

29. NO THIRD PARTY BENEFICIARIES. This Agreement does not expressly or
implicitly provide any third party (including End Users) with any remedy, claim,
liability, reimbursement, cause of action or other right or privilege.

30. NON-WAIVER. The failure of a party to enforce any right under this Agreement
at any particular point in time shall not constitute a continuing waiver of any
such right with respect to the remaining term of this Agreement, or the waiver
of any other right under this Agreement.

31. SEVERABILITY. If any portion of this Agreement is found to be invalid or
unenforceable, the remaining provisions shall remain in effect and the parties
shall immediately begin negotiations to replace any invalid or unenforceable
portions that are essential parts of this Agreement.

32. SURVIVAL OF TERMS. The rights and obligations of either party that by their
nature would continue beyond the termination or expiration of this Agreement
shall survive termination or expiration of this Agreement. For example, the
provisions of this Agreement regarding Confidentiality shall remain in effect
for 2 years following termination of this Agreement and the provisions of this
Agreement regarding arbitration, indemnification, and/or limitation of liability
shall survive termination of this Agreement as to any cause of action arising
under the Agreement.

33. CHOICE OF LAW. The domestic law of the State of New York, except its
conflict-of-laws rules, shall govern the construction, interpretation, and
performance of this Agreement, except to the extent superceded by federal law.

34. AMENDMENT. No amendment, supplement, modification or waiver of any provision
of this Agreement shall be effective unless in writing and signed by authorized
representatives of both parties.

35. ENTIRE AGREEMENT. This Agreement constitutes the entire agreement between
the parties with respect to the Services. This Agreement supersedes all prior
agreements, proposals, representations, statements or understandings, whether
written or oral, concerning the Services or the parties' rights or obligations
relating to the Services. Any prior representations, promises, inducements or
statements of intent regarding the Services that are not embodied in this
Agreement are of no effect.

36. DEFINITIONS. The following definitions apply in addition to the definitions
set forth elsewhere in this Agreement:

"Affiliate" - any entity that controls, is controlled by or is under common
control with a party.

"End User" - the entity that actually uses the service resold by CUSTOMER.

"Intermediate Reseller" - any reseller or other intermediary (other than

detariffing.

If not otherwise defined, capitalized terms shall be defined as provided in
AT&T's Tariffs.

        Agreement.

3.      MINIMUM REVENUE COMMITMENTS (MRC). The following Minimum Revenue

        commitment. If CUSTOMER fails to meet any Minimum Revenue Commitment in

        Eligible Charges for that Minimum Revenue Commitment incurred during the
        Commitment Period. [***]

                      increase any Adjustable MMRC to an amount that is less
                      than or equal to the CUSTOMER's billed MMRC Eligible
                      Charges for the most recent billing month, by providing
                      written notice to AT&T at least 30 days prior to the

                      apply.

        B.     ADJUSTABLE PRIVATE LINE AND SATELLITE MMRC.

               1.     For Months [***] of the Term, the initial Private Line and
                      Satellite MMRC is [***] Dollars. Beginning in Month [***]
                      through Month [***] of the Term, the initial Private Line
                      and Satellite MMRC is [***] Dollars. The Private Line and
                      Satellite MMRC is an adjustable MMRC described above. Each
                      month of the Term is a Commitment Period.

               2.     The Private Line and Satellite MMRC applies to the
                      following Services provided under this Attachment, except
