ITEM 1. BUSINESS

OVERVIEW

        We are one of the leading European providers of managed bandwidth and
related telecommunications services to telecommunications carriers, Internet
service providers and other bandwidth-intensive customers. We operate the
largest centrally managed fiber optic network in Europe over which we offer a
broad and sophisticated range of services. In addition, we operate a Tier-1
Internet backbone network that connects European Internet service providers to
the Internet. We believe our early entry into the market, supported by the reach
of our high capacity network, a low cost position and our focus on building
strategic relationships with our customers, has allowed us to create sustainable
advantages in a large and growing market.

        At December 31, 1999, we had 105 customers under contract for service on
our network. At December 31, 1999, our customers were contractually obligated to
pay us an aggregate of approximately $635.0 million for future services,
provided we perform in accordance with contractual specifications. This amount
is inclusive of amounts included in deferred revenue.

       Our network, which covers approximately 17,000 kilometers connecting 29
cities in 12 European countries, reaches a substantial portion of our targeted
customer base. We expect our network to extend approximately 25,000 kilometers
with points of presence in approximately 20 European countries by the end of
2000. Thereafter, additional points of presence will be added to our network as
warranted by customer demand. We also provide services that connect Europe to
the United States in order to address a significant portion of the market growth
which is Internet and Internet protocol related. This service is currently
provided through capacity leased from third parties. In December, 1999, we
purchased a dedicated fiber pair on the FLAG Atlantic-1 transatlantic fiber
optic link. We expect to begin offering unprotected services in the first
quarter of 2001 and fully protected services in the second quarter of 2001 over
this fiber pair. By owning this fiber pair, we will acquire capacity of 70
gigabits per second, upgradeable to a maximum capacity of 400 gigabits per
second of fully protected capacity connecting the New York City area to our
European network. In order to meet and support the continuous increase in
bandwidth requirements of our current and future customers, we are upgrading
transmission equipment on our fiber optic network that uses dense wavelength
division multiplexing technology to substantially increase our network's
transmission capacity. In addition, we intend to develop an additional ring on
our network connecting the core cities of London, Paris, Amsterdam, Frankfurt,
Dusseldorf and Brussels with cable duct that will accommodate up to 144 fibers.
We also plan to install transmission equipment on a second, currently installed
fiber pair on a number of routes in our network to expand the transmission
capacity of those routes.

        Dense wavelength division multiplexing, or DWDM, is a technology that
allows transmission of multiple waves of light over a single fiber optic strand,
thereby increasing network capacity. By using current dense wavelength division
multiplexing technology, we are currently able to derive up to 40 wavelengths
per fiber optic pair, each wavelength with a capacity of 2.5 gigabits per
second, for a total capacity of 100 gigabits per second over a single fiber
optic strand. By year-end 2000, we expect to be able to derive up to 96
wavelengths per fiber optic pair, each wavelength with a capacity of 10 gigabits
per second, for a total capacity of 960 gigabits per second over a single fiber
optic strand, or nearly 1 terabit (or 1 trillion bits) per second.

        We began providing services to our customers in November 1996. We
believe that our early entry into the European carriers' carrier market has
provided us with several competitive advantages over other providers of
telecommunications services to telecommunications carriers, Internet service
providers and other bandwidth-intensive customers. We believe we are a pioneer
in Europe in fiber optic network deployment and service development. We have
established long-term contracts with telecommunications carriers, Internet
service providers and other bandwidth-intensive customers in some instances
capturing some of the new customers in some of the most rapidly growing market
segments. In many cases, by providing mission-critical value-added solutions to
our customers we seek to establish ourselves as their strategic partner. This
degree of integration in our customers' operations has often provided us with
the opportunity to introduce and implement additional products and services with
the customer, thereby enabling us to further penetrate our customer base. As a
result of our strong position in the European telecommunications market, we have
been able to attract and retain a talented, multi-cultural, highly skilled
workforce specialized in our leading-edge technological industry.

         Our customers include:

                  o European incumbent telecommunications operators

                  o alternative carriers

                  o voice resellers



                                       3
<PAGE>   4


                  o international carriers

                  o national Internet service providers

                  o multinational Internet service providers

                  o value added network service providers

                  o Web-centric and media-centric companies

        We believe that cross-border transmission capacity will increasingly be
used to transport data as the volume of data traffic will substantially exceed
voice traffic. This trend is being driven by the rapid growth of the Internet
and other data-intensive applications, such as electronic commerce, application
hosting, video-conferencing and multimedia applications, that require
high-quality and cost-effective transmission capacity.

        We intend to continue to participate in this rapidly growing market by
providing comprehensive telecommunications transport services to established and
emerging telecommunications carriers, Internet service providers and other
bandwidth-intensive customers. Since we are providing for a significant amount
of redundancy in the construction of our network, we expect to be able to
satisfy increasing capacity demands from our customers by placing into service
additional fiber pairs as well as implementing dense wavelength division
multiplexing upgrades on our network. We believe that our customers will
increasingly demand Internet or Internet protocol based services such as
Internet access, Web-hosting and data management services in order to
participate in the expected growth of data communication and the Internet. In
order to reinforce our leadership position, we will continue to add new services
on our network and sell our services in additional markets throughout Europe. We
also intend to invest in additional infrastructure that can further lower our
costs.

OUR STRATEGY

        Our goals are to reinforce our position as Europe's leading independent
provider of managed bandwidth and related telecommunications services to
telecommunications carriers, Internet service providers and other
bandwidth-intensive customers and, taking advantage of our leadership position,
capture additional revenues by extending our network closer to our customers and
providing new and enhanced services. The key elements of our strategy for
achieving these goals are to:

        o       Maintain our leadership position by delivering services which
                leverage our low cost position. We intend to continue to
                leverage our position as a low-cost provider of flexible and
                high capacity products and services. We have planned and
                implemented our network development to ensure that we have a
                supply of capacity adequate to meet our customers' demands and
                have reduced our cost basis by investing in new technologies. We
                have priced our capacity to capture market share and to fulfill
                an increasing demand for bandwidth. We believe that by making
                available increased supplies of capacity at appropriate prices,
                we can sustain attractive margins over an expanding capacity
                base even as more competitors enter the market.

        o       Build on our experience as a first mover in the European
                carriers' carrier market to further penetrate our existing
                customer base and expand our service portfolio. We are the first
                European company to operate a centrally managed pan-European
                fiber optic network. Since we began offering service on our
                network, we have developed a significant customer base
                encompassing over 150 telecommunications carriers, Internet
                service providers and other bandwidth-intensive customers. As a
                result of being first in the market, we have gained significant
                experience in how to tailor our service offering to meet our
                customers' rapidly evolving needs and have developed service
                innovations. By providing mission-critical value added solutions
                to our customers, we seek to establish ourselves as their
                strategic partner. We will seek to further penetrate our
                customer base and strengthen our customer relationships by
                continuing to develop service innovations that enable us to
                deliver the lowest cost and highest quality transport service
                for our customers. Our managed gigabit network is a service that
                we recently introduced that we believe shows our commitment to
                being at the forefront of innovations among European providers
                of bandwidth services.

        o       Capitalizing on the experience of our management and workforce.
                We have assembled and will continue to build a management team
                and highly skilled workforce with significant expertise in the
                design, engineering, construction, operation, maintenance and
                enhancement of fiber optic network. Due to our early entry in
                the European bandwidth services market, our workforce has gained
                extensive experience in marketing, selling, configuring and
                providing customer support for the tailored solutions that we
                offer our customers. We intend to build on this experience and
                expertise in order to develop new and enhanced products and
                services that enable us to strengthen our customer relationships
                and generate additional revenues.

        o       Focus on bandwidth-intensive customers. We intend to continue to
                focus on providing high-quality telecommunications services to
                carriers, Internet service providers and other
                bandwidth-intensive customers to enable these operators to more
                successfully meet the needs of their own end-user customers. We
                believe this should enable us to provide superior customer
                service while avoiding investments in billing and related
                systems and general administrative costs associated with retail
                operations. In addition, we intend to continue to focus on
                emerging data-centric companies that require large amounts of
                bandwidth to service their end-user customers. These types of
                customers include broadband multimedia providers such as UPC's
                chello broadband, content providers such as motion picture
                studios and broadcasters, Internet applications providers such
                as portals and electronic commerce companies, and emerging data
                transmission providers such as wireless operators. The Internet
                and the general acceptance of Internet protocol as a worldwide
                transmission standard are fostering the emergence of these new
                market segments.

        o       Continue to invest in the reach and capacity of our network. We
                will continue to invest in our network to expand its geographic
                reach and capacity in order to ensure that we can accommodate
                our customers' future capacity requirements. We are continuing
                to build our network by extending its coverage to include
                approximately 25,000 kilometers across Europe by the end of
                2000. We are continuing to deploy dense wavelength division
                multiplexing technology that will permit significant enhancement
                of our network's transmission capacity and will allow us to
                upgrade the capacity, reliability and efficiency of the network
                in the future. The capacity of our network is currently 40
                wavelengths per fiber optic pair, each wavelength with a
                capacity of 2.5 gigabits per second, or a total capacity of 100
                gigabits per second on the majority of our routes. We intend to
                install additional upgrades to further increase our network's
                capacity in 2000. When introduced, these upgrades are expected
                to increase the capacity of a single fiber pair to 96
                wavelengths per fiber optic pair, each wavelength with a
                capacity of 10 gigabits per second, or a total capacity of 960
                gigabits per second. In addition, we intend to develop an
                additional ring on our network connecting the core cities of
                London, Paris, Amsterdam, Frankfurt, Dusseldorf and Brussels
                with cable duct that will accommodate up to 144 fibers. We also
                plan to install transmission equipment on a second, currently
                installed fiber pair on a number of routes in our network to
                expand the transmission capacity of those routes.

        o       Extend our network closer to our customers and offer new and
                enhanced services.

        o       Develop City Enterprise Networks. In order to offer true
                end-to-end transmission services to our carrier and other
                bandwidth intensive customers, we intend to build intracity
                fiber networks, called City Enterprise Networks, in major
                European cities. Through us and other subsidiaries, our parent
                GTS currently operates five such networks, in Paris, Budapest,
                Prague, Berlin and Geneva. We expect to have deployed intracity
                fiber networks in eight additional cities by the end of 2000.
                Each City Enterprise Network will be designed to connect, within
                a city, the major telecommunications transmission centers,
                including points of presence on our network, points of presence
                of our affiliates in such city, telehouses, Internet protocol
                exchange points and, where economically feasible our existing
                customers' points of presence in that city. This will allow us
                to reach our customers without relying on third-party local
                access providers. We expect an increase in service quality and
                higher margins as traffic will be managed on-net end-to-end,
                leading to an enhanced competitiveness of our service portfolio.

        o       Expand and enhance the transatlantic capacity of our network. We
                believe that a large portion of our market growth will come in
                the form of Internet protocol-based data and voice services. We
                currently lease transatlantic capacity from third parties.
                Because a majority of Internet protocol traffic originates in
                the United States, we have acquired a dedicated fiber pair on
                the FLAG Atlantic-1 transatlantic fiber optic link. By owning
                this fiber pair, we will acquire capacity of 70 gigabits per
                second upgradeable up to a maximum of 400 gigabits per second of
                fully protected capacity from the New York City area directly to
                our European network. We believe that owning a large volume of
                transatlantic capacity to and from the United States will
                enhance our competitive low cost position in Europe while
                extending our network to the United States at favorable prices.
                In addition, in order to maintain and reinforce our strong
                market position in the increasingly global carriers' carrier
                market and data-centric market, we are planning to enter into
                arrangements to obtain network capacity connecting several key
                U.S. markets by the end of 2000.

        o       Capitalize on demand for Web-based services and products. We
                intend to capitalize on the trend of companies seeking to
                outsource their critical business applications and integrate
                Web-based services and products into their marketing efforts by
                aggressively developing data- and Web-hosting centers in key
                cities in Europe. We intend to open data- and Web-hosting
                centers in up to 13 major European cities by year-end 2001. By
                mid-2000, we expect to establish data- and Web-hosting
                capability in London, Amsterdam, Frankfurt and Paris. These
                centers are a natural extension of our strategy to meet the
                end-to-end needs of the Web- and media-centric content and
                application providers who are leading the rapid growth of the
                Internet- and multimedia-related segments of our target markets
                in Europe. In addition to carrying these customers'
                international traffic on our network, we will be able to host
                and distribute their applications, support their electronic
                commerce activities and provide peering arrangements.

OUR SERVICES

        We offer our customers high-quality transmission services and extended
network capabilities at competitive prices. The diverse services we offer
reflect the complex and dynamic nature of the carrier market and the rapidly
evolving Web-centric market. We have developed a broad range of services that
vary in technology (synchronous digital hierarchy, dense wavelength division
multiplexing, Internet protocol), configuration (point-to-point, ring, virtual
network services), quality requirements and geographical reach (domestic,
pan-European, transatlantic services). Service innovation and the ability to
package and price services flexibly have allowed us to serve the needs of our
customers effectively.

        Our service offering has the following competitive advantages:

          o     Tailored solutions. We have significant experience in tailoring
                highly customized contract terms and volume discounts that allow
                our customers to select varying capacity, access, guaranteed
                availability and contract terms.

          o     High capacity cross-border network facilities. Our dense
                wavelength division multiplexing network provides high capacity
                cross-border network facilities without requiring customers to
                invest in network infrastructure or to be constrained by a
                narrow range of capacity offerings.

          o     Diverse routing. The fiber optic network's diverse, redundant
                routes are designed to allow us to provide strong performance
                commitments. On most routes the fiber optic network performed at
                over 99.9% availability.

          o     Cost reduction through advanced technology. We have
                substantially reduced our unit cost by increasing the available
                capacity on a fiber pair and deploying advanced dense wavelength
                division multiplexing technology on the majority of our routes.

          o     Uniform network architecture. The uniform technology of our
                international managed transmission network allows us to provide
                a better quality and reliability of service as well as
                uniformity of features throughout our fiber optic network.

        In addition to providing sophisticated and flexible value-added
services, we intend to quickly and efficiently deploy our network presence
wherever our current and future customers need to originate and/or terminate
traffic. This has led to the rapid expansion of our network throughout Europe,
as well as to our purchase of transatlantic transmission capacity.

        We continue to focus on maintaining a low-cost position for our evolving
services in our network deployment efforts. Through the increase in available
capacity on a fiber pair and through advances in dense wavelength division
multiplexing technology, we have substantially reduced our unit cost since we
began operations.

MANAGED BANDWIDTH SERVICES

        We primarily provide large capacity cross-border European and
transatlantic services over an integrated, managed network. Our network, based
on dense wavelength division multiplexing and synchronous digital hierarchy
technology, provides digital transmission capability upon which a broad range of
advanced applications may be built. Our network offers network availability,
flexibility, reliability and bandwidth speeds not widely available for transport
of telecommunications traffic across national borders in Western Europe. Our
network is designed to provide customers with a wide variety of bandwidth
speeds, ranging from a data transmission rate of 2 megabits per second to a data
transmission rate of 2.5 gigabits per second. Access to our network allows our
customers to rapidly enter the markets they are targeting while benefitting from
the low unit cost that our network provides.

        Tailored to meet the diverse requirements of several customer segments,
our services include two classes of outsourcing levels. First, our unprotected
ring services provide diversely routed paths on which customers deploy their own
termination equipment and perform protection schemes themselves. Second, our
protected services provide self-healing point-to-point links managed end-to-end
by us. Depending on the customer's bandwidth and application requirements, these
two classes of bandwidth services run on two underlying technologies: either
synchronous digital hierarchy technology over dense wavelength division
multiplexing (for speeds ranging from 2 megabits per second to 155 megabits per
second) or directly on dense wavelength division multiplexing (for speeds
ranging from 155 megabits per second to 2.5 gigabits per second).

        Services using synchronous digital hierarchy technology may include
local access capacity between our network point of presence and the customer's
point of presence, depending on customer requirements, due to our numerous
agreements with local access providers.



                                       6
<PAGE>   7


        Services using dense wavelength division multiplexing technology are
delivered on a standard basis at our point of presence. On a special project
basis and shortly through our City Enterprise Network, dense wavelength division
multiplexing services may be expanded to the customer's point of presence.

DIVERSELY ROUTED RING SERVICES

        Many medium to large carriers and operators purchase network capacity in
excess of actual requirements and prefer to have control over the physical
configuration of their networks. This service connects multiple customer
locations with diverse routed paths in a ring configuration. Through its own
termination equipment, the customer has full control of its different traffic
flows. Configuration changes can be made directly by the customer at any time
without our involvement. This gives the customer the opportunity to optimize its
usage of the available ring bandwidth based on the volume requirements of its
individual applications.

        These services are available at speeds of 45 and 155 megabits per second
using synchronous digital hierarchy over dense wavelength division multiplexing
technology as well as directly on dense wavelength division multiplexing
technology at speeds of 2.5 gigabits per second which is expected to be upgraded
to 10 gigabits per second in 2000.

PROTECTED SERVICES

        Our protected services offer domestic and international point-to-point
transmission capacity across our pan-European network. Our services are designed
with a stand-by capacity on our network, fully-dedicated to protecting the
working bandwidth. As a result, the customer avoids having to provide for the
redundancy of its traffic, as it would for unprotected services. We therefore
manage the end-to-end bandwidth reliability of the customer's circuit. We offer
customers service level agreements with service guarantees appropriate for
mission-critical applications These guarantees cover on-time service delivery
and service availability.

        Due to the availability of a broad range of bandwidths, its attractive
pricing structure and the quality of service guarantees it offers, we believe
this service is a significant improvement to international private leased
circuits. These services are available in bandwidths from 2 megabits per second
to multiples of 140 megabits per second or 155 megabits per second using
synchronous digital hierarchy over dense wavelength division multiplexing
technology. A similar service running directly on dense wavelength division
multiplexing technology is currently under development.

        Our existing transatlantic capacity allows us to provide, manage and
maintain end-to-end bandwidth requirements of our customers between the New York
City area and any points of presence on our network in Europe at data
transmission rates of 34 megabits per second, 45 megabits per second and 155
megabits per second.

INTERNET PROTOCOL TRANSIT SERVICES

        The current and future growth in the Internet has a significant impact
on the carrier business. In addition to increasing the amount of data that is
being transported across borders, the Internet influences the transport
technologies, the traffic patterns and the segments that require carrier-like
services.

        Through our GTS Ebone brand name, we offer to Internet service
providers, value added network service providers, multimedia providers and
Web-hosting companies a carriers'-grade Internet access service with the
following significant features:

          o     Reliable access to Internet service throughout Europe and the
                United States, which is made possible by maintaining multiple
                relationships with different Tier-1 Internet backbone providers,
                both in the United States as well as in Europe;

          o     A network consisting of interconnecting rings and based on dense
                wavelength division multiplexing technology, which ensures an
                ample supply of bandwidth;

          o     Access to one of the largest installed bases of Internet service
                providers in Europe;

          o     Access to other Internet networks through peering arrangements
                with Tier-1 Internet backbones in Europe and in the United
                States; and

          o     Access speeds ranging from 2 megabits per second to 2.5 gigabits
                per second.



                                       7
<PAGE>   8


          We offer two types of GTS Ebone services:

          o     Ebone Global Carrier Services, which provides general purpose,
                congestion free access to the worldwide Internet; and

          o     Ebone Europe Carrier Services, which is focused on low delay,
                high performance access to the European domain of the worldwide
                Internet.

        In addition, we are using optical Internet protocol technology to offer
in Europe real-time Internet protocol performance that is needed by Internet
protocol operators and by providers of voice, fax and video-
over-Internet-protocol services. GTS Ebone Europe Services is the first of a
series of future services to fully benefit from the performance offered by
optical Internet technology.

PLANNED INITIATIVES

TRANSATLANTIC EXPANSION OF OUR NETWORK

        We currently provide connectivity between Europe to the United States
through capacity leased from third parties. In January 1999, a subsidiary of
GTS, our parent, entered into an agreement with FLAG Telecom, to establish a
50/50 joint venture to build and operate the world's first transatlantic dual
cable system designed to carry voice, high-speed data and video traffic at data
transmission rates of up to 2.4 terabits per second. The joint venture has
announced that this high-capacity fiber optic link between Europe and the United
States, which is called FLAG Atlantic-1, is expected to begin offering
unprotected services in the first quarter of 2001 and fully protected services
in the second quarter of 2001. The joint venture plans to offer a direct link
between the New York City area, London and Paris.

        On October 13, 1999, GTS announced that it has committed to purchase one
dedicated fiber pair on FLAG Atlantic-1. We purchased this fiber pair from GTS
in December 1999. By owning this fiber pair, we will acquire capacity of 70
gigabits per second upgradeable to a maximum capacity of 400 gigabits per second
of fully protected capacity (or 800 gigabits per second of unprotected capacity)
from the New York City area directly to our network in Europe. This supply of
capacity will allow us to accommodate the growing volume of transatlantic
traffic at a competitive low cost base. We expect to commence service on our
fiber pair at the same time that FLAG Atlantic-1 begins offering services.

        Finally, we have identified the need to be able to offer services beyond
the New York City area, our current point of presence in the United States. We
therefore expect to lease substantial network capacity connecting several key
U.S. markets by the end of 2000.

CITY ENTERPRISE NETWORKS

        In order to originate and/or terminate our transmission services closer
to our customers, we intend to build intracity fiber networks, called City
Enterprise Networks, in major European cities. Each City Enterprise Network
will, subject to regulatory constraints and market conditions, consist of up to
144 fiber pairs in underground ducts that we will buy, lease or lay. We believe
this high number of fiber pairs is justified by the economies of the
short-distance environment of city centers and the higher numbers of connection
points to link customers to the network. We also expect to install dense
wavelength division multiplexing equipment to enhance the efficiency of the City
Enterprise Networks.

        Each City Enterprise Network will typically connect, within a city, the
major telecommunications transmission centers, including, points of presence of
our network in such city, points of presence of our affiliates in such city,
telehouses, Internet protocol exchange points and, where economically feasible,
points of presence of our existing customers in such city.

        Relying on our own local infrastructure in key cities through our City
Enterprise Networks will allow us to reduce operating expenses (by avoiding or
reducing our payments to local access providers) and to enhance the robustness
of our network (through end-to-end network management and compatibility of the
City Enterprise Networks with our existing network). Such fully integrated
network of intracity and intercity connectivity will, we believe, appeal to our
customers in need of managed bandwidth services. We also plan to introduce
wavelength services, also known as optical sub-networks during the build-out of
our City Enterprise Networks. In addition, we plan to add fiber "sub-rings" to
the core of our City Enterprise Networks to extend our geographic reach. We will
also connect our data- and Web-hosting centers to the initial core rings. By
offering co-location and data- and Web-hosting capabilities as a bundled product
with our broadband network capabilities, we intend to attract Web-centric and
media-centric companies to our network without procuring expensive services from
local access providers.

        Through us and other subsidiaries, our parent GTS currently operates
City Enterprise Networks in Berlin, Paris, Budapest, Prague and Geneva. We do
not currently expect to own or operate the City Enterprise Networks in Paris,
Berlin, Prague or Budapest. Therefore, we may in the future purchase local
connectivity on those City Enterprise Networks for resale to our customers. We
have



                                       8
<PAGE>   9


accelerated our rollout plans and we expect to have City Enterprise Networks
operational in the following eight additional cities by mid-year 2000:

          o     Stockholm
          o     Frankfurt
          o     London
          o     Amsterdam
          o     Madrid
          o     Vienna
          o     Milan
          o     Zurich

     We are also evaluating construction of City Enterprise Networks in the
following additional cities:

          o     Brussels
          o     Munich
          o     Barcelona
          o     Stuttgart
          o     Dusseldorf

     Our intracity network rings in Western Europe will eventually connect
customers at data transmission rates of up to 2.5 gigabits per second.

DATA AND WEB-HOSTING CENTERS

     Our strategy is to strengthen our offering of Internet protocol transit
services by deploying, or arranging for capacity at, data- and Web-hosting
centers near key public Internet exchange points. This will establish the
necessary capability to undertake data- and Web-hosting services and facilitate
electronic commerce solutions. This capability will allow us to meet the
end-to-end needs of the providers of Web and media-centric content and
applications that are leading the rapid growth of the Internet and multimedia
related segments of our target markets in Europe. Thus, in addition to carrying
these customers' international traffic on our network, we will be able to host
and distribute their applications, support their e-business activities and
provide peering arrangements.

     By mid-2000, we expect to establish data- and Web-hosting capacity in
London, Frankfurt, Paris and Amsterdam. We intend to construct, or arrange for
capacity at, up to nine additional data- and Web-hosting centers during the next
two years. These facilities will be specifically designed or selected to offer
high-speed access to our network and provide co-location, dedicated and shared
data- and Web-hosting services.

     Additional benefits of the data- and Web-hosting centers include:

          o     providing Internet service providers with telehousing and
                managed services for their Internet protocol routers and
                servers;

          o     providing an NT or UNIX based server, allowing Internet service
                providers and Web-centric companies to take full advantage of
                our expertise in traffic and server management; and

          o     providing a shared server and management, offering an entry
                solution to emerging Internet service providers and Web-centric
                companies at a reasonable cost.

     Increasing Internet demand is driving Internet service providers to
co-locate their servers and Internet protocol routers closer to their customers,
thereby improving their network reach and performance. Data- and Web-hosting
centers directly connecting Web servers to an Internet protocol backbone remove
the bottlenecks associated with traditional hosting facilities. In addition,
increasing demand for Web content is driving Web-centric companies to locate
servers at those facilities to ensure superior Internet connectivity. Our data-
and Web-hosting capability will offer seamless and scalable Internet
pan-European for emerging Internet service providers and Web-centric companies,
offering direct connection to our large seamless network at bandwidths of
initially 2.5 gigabits per second, with upgrades up to 10 gigabits per second.
We believe that offering data-and Web-hosting services will provide
opportunities to cross-sell services on our fiber optic network, thereby
improving customer retention and enabling us to address new target segments.

     We will offer high performance distribution of bandwidth intensive,
multimedia applications and regional content through our extensive peering
arrangements. Our networked data- and Web-hosting centers are a key component of
the infrastructure required to



                                       9
<PAGE>   10

serve the future needs of our customer segments. We plan to extend data- and
Web-hosting and co-location services to enable application service providers to
distribute applications from their data- and Web-hosting centers. We also intend
to offer Internet service providers network-based application services such as
unified messaging and facilitate electronic commerce solutions through our data-
and Web-hosting centers.

PRICING AND DISTRIBUTION

     Sales of our services are currently conducted through our subsidiary GTS
Carrier Services (Ireland) Limited.

     Currently, the price of cross-border pan-European calls are often
significantly higher than the underlying cost of transmission and terminating
such calls and higher than the price of intra-country calls or transborder calls
to and from liberalized markets. The low cost of operating the network enables
us to attractively and competitively price our services in the face of declining
overall prices for telecommunication services. Our low-cost basis is due to,
among other things, our network's use of advanced fiber optic cable and
electronic equipment permitting high capacity transmission over longer distances
between regeneration/amplifier facilities than legacy networks.

     The term of a typical customer agreement currently ranges from one to three
years in length. In addition, we offer ten year leases which require an up-front
payment and produce recurring operation and maintenance charges. Our customer
agrees to purchase, and we agree to provide, transmission services. In general
our customer agrees to pay certain non-recurring charges upfront and recurring
charges on an annual basis, payable in twelve monthly installments. If a
customer terminates a service order prior to the end of the contract term, the
customer is generally required to pay us a cancellation charge equal to three
months of service for each of the twelve months remaining in the contract term.
We typically guarantee transmission services to a specified service level. If
such levels are not met or we fail to deliver service by the committed delivery
date, the customer is eligible for a credit against charges otherwise payable in
respect of the relevant link. Throughout 1999, a number of existing customers
have converted from short-to long-term contracts, including ten-year contracts
in which revenues are recognized ratably over the life of the contract. We
expect this trend will continue in 2000.

CUSTOMERS

     Our high capacity, dense wavelength division multiplexing and synchronous
digital hierarchy based fiber optic network is designed to enable incumbent
telecommunications operators, Internet service providers and other
bandwidth-intensive customers to integrate high quality, cross-border capacity
into their end user offerings. At December 31, 1999, approximately 180 customers
were under contract for service on our network. These customers included
incumbent telecommunications operators, alternative carriers, voice resellers,
international carriers, national Internet service providers, multinational
Internet service providers, value added network service providers and
Web-centric and media-centric companies. As of December 31, 1999, our customers
were contractually obligated to pay us approximately $635.0 million for future
services, provided our network performs in accordance with contractual
specifications. This amount is inclusive of amounts included in deferred
revenue.

     We target eight major market segments or customer groups, which can be
characterized as follows:

     o    European Incumbent Telecommunications Operators. This customer group
          consists of the traditional European incumbent telecommunications
          operators that generally participate in the standard bilateral
          agreements for cross-border connections. We lower the cost of
          delivering their international service and provide a vehicle for them
          to compete in non-domestic markets.

     o    Alternative Carriers. This group consists of second carriers, mobile
          carriers and competitive access providers. These new carriers have
          chosen to compete with the incumbent telecommunications operators in
          their respective countries. We provide these companies with the
          capacity to enter markets quickly and competitive costs for their
          international services and/or national infrastructure.

     o    Voice Resellers. Voice resellers are voice carriers that do not own
          transmission facilities, but obtain communications services from other
          carriers for resale to the public. Voice resellers are also a growing
          segment of the market and are expected to increase their market share
          in conjunction with the liberalization of the European
          telecommunications market. In the United States, for example, voice
          resellers were a significant factor in the expansion of competition.

     o    International Carriers. This customer group consists of multinational
          carriers with traffic between European and other international
          gateways. We can provide these customers a pan-European distribution
          network to gather and deliver traffic to and from their own and other
          networks.



                                       10
<PAGE>   11

     o    National Internet Services Providers. Internet service providers are a
          fast growing segment generating significant bandwidth requirements.
          These customers provide Internet access, web-hosting and related value
          added services to a national customer base. They can be independent,
          owned by cable TV companies, incumbent or alternative operators. They
          originate and terminate large amounts of international Internet
          traffic, for which they typically require congestion-free Internet
          access. Alternatively, these customers require large managed bandwidth
          capacity to U.S. Internet providers. Our GTS Ebone Europe services,
          based on our large pan-European optical Internet protocol network with
          multiple connections to key U.S. backbones, position us well to serve
          this segment.

     o    Multinational Internet Service Providers. These customers provide
          Internet access, web-hosting and related value added services to
          multiple national customer bases and to international business
          customers. In addition to the traffic generated between their national
          networks, they originate and terminate large amounts of international
          Internet traffic. They typically require large managed bandwidth
          capacity to their core Internet protocol backbone in the United
          States, completed by congestion-free Internet access to the European
          domains of the worldwide Internet. Alternatively, these customers
          require bandwidth between Internet exchanges (point of interconnection
          between local Internet service providers) in different European
          countries. Our extensive pan-European and transatlantic bandwidth
          services, combined with our GTS Ebone Europe services, allow us to
          serve this segment effectively.

     o    Value Added Network Service Providers. Value added networks are data
          communications systems in which special service features enhance the
          basic data transmission facilities offered to customers. Value added
          networks currently purchase their own international circuits and build
          the required amount of resiliency into their network infrastructure.
          Such value added network service providers are often offered by global
          consortia of telecommunications operators, which have pooled their
          resources in order to compete more effectively in important
          telecommunications markets, such as those in Western Europe,
          particularly outside their home market. We allow such customers to
          meet their needs cost-effectively and to extend their services to new
          markets or customers without substantial capital investment. These
          providers build data communications systems in which added value
          services (for example, Frame Relay, ATM, LAN-Interconnect) enhance the
          basic data transmission facilities offered to customers. Many of these
          networks are targeted to the data transfer requirements of specific
          international customer segments such as airlines and financial
          institutions.

     o    Web-centric and Media-centric Companies. The emergence of the Internet
          is causing many companies of all sizes and sectors to rely on Web
          presence to expand their businesses. These companies need
          congestion-free highly reliable Internet access and presence which
          makes them our natural target given our Internet protocol network and
          installed user base in Europe. Their requirements in terms of
          Web-hosting and European-focused Internet access lead them to demand
          the carrier-quality Internet solutions. We expect that the performance
          made possible by our implementation of optical Internet protocol
          technology will trigger the emergence of new broadband applications,
          such as streaming audio or cable TV programming distribution to the
          end-user via the Internet.

     We expect that additional demand for services will be derived from
increased Internet usage caused by the subscription-free Internet phenomenon and
usage of dedicated circuits, as well as the exponential increase in volume
caused by new Internet applications, such as voice-over Internet protocol,
broadband applications, electronic commerce applications and Web-hosting, and
the wider deployment of corporate data solutions.

NETWORK DESIGN

     The design of our network is based on a layered architecture which
separates the physical layer, the optical layer, the transmission layers and the
data (Internet protocol) layer of our network with standard interfaces and
protocols in order to optimize design and operation and provide flexibility for
introducing new technologies, new applications and new services.

     The physical layer of our network is based on a mesh of dark fiber routes
interconnecting cities on our network via at least two or three physically
diverse paths for maximum resilience against fiber or facilities failures. In
each major city there will be two additional customer access sites for
reliability.

     The optical layer of our network represents the core of our network and is
based on dense wavelength division multiplexing. This layer supports the
provision of optical services direct to customers at 2.5 gigabits per second and
provides for the operation of multiple synchronous digital hierarchy and/or
Internet protocol systems to run concurrently on a single fiber pair in a highly
cost efficient manner. The optical layer of our network is based on Ciena 40
wavelength systems with a capacity of 100 gigabits per second on a fiber pair.



                                       11
<PAGE>   12
     We are using synchronous digital hierarchy (SDH) time division multiplexing
equipment to consolidate, groom and add or drop low and high order traffic
coming from our various network components and to support the provision of
synchronous digital hierarchy leased lines services to customers at data
transmission rates ranging from 2 megabits per second to 155 megabits per
second.

     The synchronous digital hierarchy layer of the network runs via dense
wavelength division multiplexing channels in our network with a multilayered
architecture consisting of multiple synchronous digital hierarchy rings
optimized for different traffic characteristics. Each synchronous digital
hierarchy ring supports full automatic re-routing of traffic in the case of a
break in the ring. This layer is based on Alcatel STM-16 (2.5 gigabits per
second) systems, which are installed throughout the operational network.

     A gigabit Internet protocol layer is implemented using the latest
generation of Internet protocol routing equipment, the Cisco GSR 12000. Backbone
links interconnect core network nodes at data transmission rates of 2.5 gigabits
per second, providing high quality, seamless Internet protocol connections
throughout Europe. The Internet protocol connections gigabit routers are coupled
directly to the optical wavelength division multiplexing infrastructure without
any additional intermediate equipment, reducing network complexity and costs and
increasing efficiency. Core network routers are deployed in a redundant
configuration to ensure maximum reliability. Since we design and operate
directly both the optical network layer and the Internet protocol layer, a
further optimization of the resulting network architecture is achieved. The
Internet application implemented on top of the gigabit Internet protocol
platform configures us among the prominent Tier-1 Internet service providers in
Europe, with direct connections to the other major European Internet backbone
providers. For a direct interconnection with major U.S. Internet backbones, two
network nodes are deployed in the United States, with high-speed connections to
the European gigabit backbone. The high-performance core Internet protocol
network is designed to support a flexible introduction of Internet protocol
based added-value services at the edge of our network.

     A main network management center, located in Brussels, controls our
network. The network operations centers can pinpoint potential service problems
and can deal with service re-routing if required much more effectively than in
networks controlled by multiple operators in different countries. Our advanced
operational support systems also allows us to manage the large number of network
components and local repair organizations required in an extensive international
network of this size, as well as for advanced customer care in managing customer
operational activities.

     Overall, our combination of backup paths and management components enable
us to recover from individual failures at the optical, synchronous digital
hierarchy and Internet protocol layers. Our resilient approach provides for a
high level of network performance and reliability. As a result, we are able to
enter into strong performance commitments with our customers, and services on
most routes of our network have performed at or above 99.9% availability.

     We own substantially all of our network equipment as well as some segments
of the fiber optic cable. A substantial part of the fiber is leased on a
long-term basis. Long-term leases for fiber are advantageous to us because they
reduce the burden of building large quantities of capacity before they can be
used. When we lease dark fiber, the infrastructure provider will generally be
responsible for maintaining such fiber optic cable. We have entered into
agreements with equipment vendors, infrastructure providers and other third
parties to supply and/or maintain the equipment for our network.

NETWORK CAPACITY

     Our network includes Ciena 40 dense wavelength division multiplexing
systems on a substantial majority of our routes and by mid-2000 all our routes
will be dense wavelength division multiplexing based with a data transmission
rate of at least 100 gigabits per second per fiber pair. This 100 gigabits per
second allows for synchronous digital hierarchy and Internet protocol systems of
2.5 gigabits per second to be installed only when required, thus providing for
efficient management of capital investment.

     We will deploy on our core pan-European fiber optic network routes, during
2000 and according to traffic demand, per core route a new generation of
wavelength division multiplexing systems scalable up to a minimum of 960
gigabits per second. These systems will be able to handle wavelengths at 2.5 and
10 gigabits per second allowing us to increase the amount of bandwidth carried
per fiber pair as well as to reduce interface prices in both wavelength division
multiplexing and client layer equipments. We plan to extend capacity in the core
portion of our network by developing an additional ring connecting London,
Paris, Amsterdam, Frankfurt, Dusseldorf and Brussels with cable duct
accommodating up to 144 fibers. We also plan to install transmission equipment
on a second, currently installed fiber pair on a number of routes in our network
to expand the transmission capacity of those routes by adding fiber pairs and
dense wavelength division multiplexing upgrades on selected existing routes
whenever demand for capacity will justify it. This approach to fiber utilization
again provides for an optimal management of fiber investment.

NETWORK AGREEMENTS

     We have entered into agreements and letters of intent with various
infrastructure providers for construction and/or leasing of dark fiber for
portions of our network. Our agreements for leases of portions of our network
typically require the infrastructure provider to


                                       12
<PAGE>   13

provide a certain number of pairs of dark fiber and in some cases facilities
along the network route commencing on dates we provide. The term of a lease
agreement generally ranges from 10 to 18 years. An agreement typically contains
optical specification standards for the fiber and methods of testing. We are
allowed to use the cable for the transmission of messages and other purposes,
including increasing capacity. The infrastructure provider is responsible for
maintenance of the cable facilities. The infrastructure provider may also
provide space for the location of our equipment and related maintenance. The
agreements typically provide for termination by the parties only for material
breach, but allow the breaching party 90 days to cure the breach. The agreements
typically contain a transition period after termination of the agreement to
allow us to continue to serve our customers until we can reach agreement with an
alternative infrastructure provider. In certain areas of our network where it is
not possible to lease dark fiber (which we do not expect to exceed more than 10
percent of our network), we have signed agreements or letters of intent for the
right to use managed bandwidth. The terms of these agreements typically range
from 10 to 25 years.

     We are also deploying our network along the rights-of-way of a variety of
alternative sources, including railways, motorways, waterways, pipelines and
utilities. We constantly evaluate multiple alternative infrastructure suppliers
in order to maximise our flexibility. Many portions of our network utilise
long-term right-of-way agreements with landowners. As a result of our network
development activities to date, we have gained access to infrastructure for our
network routes, which we believe, will be difficult for competitors to
duplicate.

COMPETITION

     We compete with various telecommunications companies, including MCI
WorldCom, Inc., Viatel, Inc., KPN Qwest B.V., COLT Telecom Group plc, Level 3
Communications, Inc., Carrier1 International S.A., Deutsche Telekom AG, France
Telecom S.A., Global Crossing Ltd. and British Telecommunications plc. Some of
these entities have announced plans to construct, have begun to construct or are
operating high bandwidth fiber optic networks across various European countries
and in several European metropolitan markets and in some cases, providing
transatlantic connectivity, which do or will compete with our network and our
planned City Enterprise Networks. In addition, a number of telecommunications
companies and Internet service providers have begun offering or announced their
intentions to offer data- and Web hosting services in key European cities.

     We compete primarily on the basis of the range and quality of services
offered, customer service and price. Competitors may force us to lower our
prices or modify our service offerings to remain competitive. Many competitors
have established customer bases and extensive brand name recognition and have
greater financial, management and other resources.

     The ongoing liberalization of the European telecommunications market has
coincided with technological innovation to create an increasingly competitive
market, characterized by still-dominant incumbent telecommunications operators
as well as an increasing number of new market entrants. In addition, these
carriers own and operate fully built networks and infrastructure which provide
them with significant cost advantages.

                         LICENSES AND REGULATORY ISSUES

OVERVIEW

     The EU has progressively liberalized its telecommunications markets over
the past decade. In 1987, a policy document, the EC Green Paper on
Telecommunications, charted the course for the current changes in the EU
telecommunications industry by advancing principles such as separation of
operators from regulators, transparency of procedures and information, cost
orientation of tariffs, access to monopoly public telephone operator networks
and the liberalization of services. In 1990, the EU adopted two measures based
on these principles: the Open Network Provision Framework Directive and the
Services Directive. These two directives set forth basic rules for access to
public telephone networks and required the liberalization of the provision of
all telecommunications services within the EU except for certain "reserved
services", including voice telephony.

     In 1992, the EU adopted the Open Network Provision Leased Line Directive,
which requires the incumbent operators to lease lines to competitors and
end-users at cost-oriented prices, and to establish cost accounting systems for
these products by the end of 1993. Even though most EU member states have
established regulatory frameworks requiring incumbent telecommunications
operators to lease lines to competitors and end-users, we believe that, in some
EU member states, such lines are not yet being offered at cost-orientated
prices.

     In October 1999, the EU Commission opened an investigation into the
condition of the provisioning and pricing of leased lines. The aim of the
investigation is to establish whether current telephone company practices
infringe EU competition rules.



                                       13
<PAGE>   14

     In 1996, the EU adopted the Full Competition Directive, which requires EU
member states to permit the provision of telecommunications services, other than
reserved services, over (1) networks established by the provider of the
services, (2) network infrastructure provided by third parties or (3) by means
of sharing of networks from July 1996. Since then, there has been an increasing
supply of such capacity offered at attractive prices from such alternative
suppliers. The Full Competition Directive also established January 1, 1998 as
the date by which all EU member states must remove all remaining restrictions on
the provision of telecommunications services, including voice telephony. A
number of EU member states were granted a delay in implementing the Full
Competition Directive. The EU member states that are still subject to the
derogation are as follows:

     (1)  Greece, through December 31, 2000;

     (2)  Ireland, through January 1, 2000; and

     (3)  Portugal, through January 1, 2000.

     Ireland, however, implemented the Full Competition Directive in December
1998.

     Subject to the foregoing, each EU member state is obliged, under EU law, to
enforce the terms of the Full Competition Directive in such a manner so as to
ensure that its aim and purpose is carried out. Enforceability of the Full
Competition Directive may be challenged at the EU level or at the EU member
state level. In practice, implementation and enforcement of the directive has
been and may also continue to be delayed on a country by country basis.

     In June 1997, the EU adopted a directive that governs the manner in which
public network operators and service providers interconnect with the incumbent
telecommunications operators' public networks. Among other things, this
directive requires EU member states to ensure that incumbent telecommunications
operators with significant market power should provide interconnection on the
basis of cost-oriented charges.

     In April 1997, the EU adopted a directive on a common framework for general
authorizations and individual licenses in the field of telecommunications
services, including networks. Licenses must be awarded through open,
non-discriminatory and transparent procedures and applications are be required
to be dealt with in a timely fashion. The number of licenses may be restricted
only to the extent required to ensure the efficient use of scarce resources,
such as radio frequencies or numbers.

     In February 1998, the EU adopted a directive on the application of the Open
Network Provision to voice telephony and on universal service.

     We believe that the adoption of the Full Competition Directive and the
various related directives adopted by the EU have resulted in the removal of
most regulatory barriers to the establishment and operation of
telecommunications infrastructure in the countries of the EU where we currently
operate.

     However, some EU member states are still in the initial stages of
liberalizing their telecommunications markets and establishing competitive
regulatory structures suitable for a competitive environment. For example, some
EU member states have only recently established a national regulatory authority.
In addition, the implementation, interpretation and enforcement of EU directives
differs significantly among the EU member states. While some EU member states
have embraced the liberalization process and achieved a high level of openness,
others have delayed the full implementation of the directives and maintained
various restrictions on full competition.

     Member states of the EU are bound as a matter of international law to
comply with certain multilateral trade rules and regulations. On February 15,
1997, over 60 members of the World Trade Organization committed to open their
telecommunications markets for basic telecommunications services to foreign
competition and ownership and to adopt regulatory measures designed to protect
foreign telecommunications providers against anticompetitive behavior by
domestic incumbent telecommunications operators. For most parties, these
commitments took effect on February 5, 1998 (including the EU member states). We
believe that this Agreement will contribute to the creation of a more
competitive environment internationally. Specifically, it will result in
downward pressure on call termination charges outside the EU. For a discussion
of the regulatory risks involved, see "Certain considerations generally
applicable to our company -- Delays in regulatory liberalization in EU member
states could adversely affect our service offerings in those countries."

     As a multinational telecommunications company, we are subject to varying
degrees of regulation in each of the jurisdictions in which we provide our
services and deploy our network. Local laws and regulations and the
interpretation of such laws and regulations differ significantly among the
jurisdictions in which we operate. For a discussion of the regulatory risks we
face, see "Certain considerations generally applicable to our company -- Delays
in regulatory liberalizations in EU member states could adversely affect our
service offerings in those countries."

GTS EUROPE NETWORK

     We require licenses, authorizations or registrations in almost all
countries to operate our network and provide our service. Licenses,
authorizations or registrations have been obtained in Austria, Belgium, Czech
Republic, Finland, France, Germany, Italy, Luxembourg, The Netherlands, Spain,
Sweden, Switzerland, the United Kingdom and the United States. No license or
authorization is required to operate our network in Denmark. We intend to file
applications in other countries in anticipation of service launch in accordance
with our network roll-out plan.

     A summary discussion of the regulatory framework in certain countries where
we have developed and are developing our network is set forth below. This
discussion is intended to provide a general outline, rather than a comprehensive
discussion, of the more relevant regulations and current regulatory posture of
the various jurisdictions.

     Austria. A new Telecommunications Act entered into force in Austria in
1997. On May 3, 1999, we were granted a concession to build and operate our
network, including our City Enterprise Networks, throughout Austria.

     Belgium. The implementing legislation regarding the licensing regimes for
the provision of voice telephony services and the establishment of public
network infrastructure entered into force in July 1998. Until such entry into
force, the Belgian Telecommunication Authority worked with a system of
provisional licenses. Through a wholly owned subsidiary, we obtained a
provisional license in February 1997 from the Belgian regulatory authority to
build infrastructure between major Belgian population centers and the relevant
border crossings. We also had an authorization to provide liberalized services
using alternative infrastructure. We were granted a permanent license to build
and operate our network on January 26, 1999. In December, 1999, we obtained an
extension to our license in order to operate routes linking a planned point of
presence in Diegem. We will be required to notify the Belgium regulator in the
event that we deploy City Enterprise Networks in Belgium.

     Czech Republic. Through a wholly owned subsidiary, we were granted a
license for the provision of our international services on October 6, 1999. The
license is valid for 10 years.

     Denmark. In July 1997, Denmark fully liberalized its telecommunications
markets in accordance with the requirements of the relevant EU Directives.
According to the Danish rules, we do not require any regulatory approval in
order to install or operate our network in Denmark.

     Finland. In 1997, Finland enacted the Telecommunications Market Act, which
brought its laws into conformity with the Full Competition Directive. The Act
requires persons intending to provide telecommunications services to notify the
responsible Ministry in advance. On July 7, 1999, the Ministry notified us that
we could provide international telecommunications services.

     France. In 1996, France approved legislation to implement the Full
Competition Directive and to remove all remaining restrictions on competition
from January 1998. On November 19, 1997, we obtained authorization to build and
operate our network in specific regions of France. In September 1998, we were
granted an extension of our authorization in order to extend our network in
France to reach Italy and Spain. Our authorization requires prior notification
to and approval by the French regulator of any substantial changes in our
capital or our controlling shareholder. The authorization is valid for 15 years.

     Germany. Germany adopted legislation implementing the Full Competition
Directive and removing all remaining restrictions on competition from August
1996. We were granted a license by the German regulatory authorities on July 18,
1997. The license permits us to build and operate the portions of our network in
Germany connecting Dusseldorf, Frankfurt and Stuttgart; Dusseldorf to the Dutch
border; and Stuttgart to the French border. In August 1998, we were granted
extensions to our license to build and operate routes linking Hamburg, Hanover,
Munich and Berlin and of routes to Denmark. On November 12, 1999, we obtained an
infrastructure nationwide license to cover all of Germany. This nationwide
license will allow us to deploy planned City Enterprise Networks in Germany.

     Italy. Although in the past Italy has been dilatory in implementing EC
liberalization measures, Italy adopted legislation in July 1997 creating an
independent national regulatory authority for the telecommunications and
audiovisual sectors. In September 1997, Italy adopted a regulation implementing
all EC directives in the telecommunications sector and since then specific laws
relating to licensing and interconnection and universal service have been
adopted. The Italian authorities granted a license to us in August 1998,





                                       15
<PAGE>   16

enabling the development of our network in the northwest region of Italy and the
offering of services in Milan. We expect to apply for an extension of our
license in order to offer services in other cities, and continue to expand our
network, including our planned City Enterprise Network, in Milan. The Italian
license is valid for 15 years.

     Luxembourg. A new Telecommunication Act entered into force in April 1997,
and a Royal Decree on licensing conditions entered into force in July 1998. On
February 11, 1999, we were granted a license to build and operate a public
telecommunications network, which is valid for 30 years.

     The Netherlands. In July 1997, the Dutch government abolished the
prohibition on the use of fixed infrastructure for the provision of competitive
public voice telephony, thereby complying with the requirements of the Full
Competition Directive six months ahead of schedule.

     A new Telecommunications Act came partly into force on December 15, 1998.
The new Act confirms the full liberalization of the telecommunications market in
accordance with EU law. The Dutch regulator granted a registration to us as a
public telecommunications network operator on March 3, 1999. This registration
supersedes a registration which was granted to us on August 1, 1996.

     Spain. Spain was granted the right to a delay in liberalizing its
telecommunications market until November 30, 1998. In April 1998, Spain adopted
the LGT, its new telecommunications law. The LGT was implemented through the use
of secondary legislation. The LGT and the secondary legislation resulted in the
full liberalization of the Spanish telecommunications market on December 1,
1998. We were granted a license to install and operate a telecommunications
network in Spain on January 14, 1999. The license is valid for 20 years.

     Sweden. Full liberalization of the Swedish telecommunications market
occurred in 1993. A new Telecommunications Act was passed in 1997 to reinforce
the powers of the national regulatory authority, to ensure conformity with EU
Directives and to supplement the pre-existing licensing regime with a general
authorization regime for certain services. We registered with Swedish
authorities and have been able to provide service in Sweden since July 1998.

     Switzerland. A new Swiss Telecommunications Law entered into force in
January 1998. Although Switzerland is not a member state of the EU, the effect
of the law is largely to mirror the EU telecommunications liberalization
directives. From that date, the existing voice telephony monopoly was abolished
and the provision of competing services fully liberalized. On September 18,
1998, the Swiss regulatory authority granted a definitive concession to us
(replacing an earlier provisional concession) to build and operate our network
in Switzerland. We are expecting to apply for an extension to our concession in
the event that we deploy City Enterprise Networks in Switzerland.

     United Kingdom. Since the elimination in 1991 of the UK telecommunications
duopoly consisting of British Telecommunications and Mercury, it has been the
stated goal of the UK regulator to create a competitive marketplace from which
detailed regulation could eventually be withdrawn. The United Kingdom has
already liberalized its market beyond the requirements of the Full Competition
Directive, and most restrictions on competition have been removed in practice as
well as in law. We have received a license from the Secretary of State for Trade
and Industry dated December 18, 1996 which grants the right to run a
telecommunications system or systems in the United Kingdom connected to overseas
telecommunications systems and to provide international services over such
systems. The license was modified on September 27, 1999, and now, in addition to
international services, the license permits us to provide domestic services over
our own system. At the same time, the term of the license was extended to 25
years.

     United States. The Federal Communications Commission ("FCC") granted a
license to us pursuant to Section 214 of the Communications Act of 1934
authorizing us to provide limited global facilities-based and global resale
services, (subject to the terms and conditions imposed by the law and
authorization), effective October 23, 1998. The Section 214 authorization does
not allow us to offer U.S. services between the United States and Hungary,
Poland, the Czech Republic, Romania, Monaco, Russia, Ukraine, Kazakhstan,
Uzbekistan, Azerbaijan, China and India. On August 16, 1999, we filed an
application with the FCC for a Section 214 authorization to provide
international facilities-based and resale service between the United States and
the latter countries. The FCC issued a public notice stating that the portion of
the application relating to service between the United States and Russia was
removed from stream line processing, and that the remainder of the application
was granted on October 13, 1999. We do not require any authorization to provide
state-to-state services within the United States. We expect to be able to obtain
any license that may be required to be issued by a state regulatory commission
to provide services between points within a single state.

     We intend to file applications in other countries including Croatia,
Hungary, Ireland, Poland, Portugal, Slovakia and Russia in anticipation of
service launch in accordance with our network roll-out plan. With the exception
of Ireland and Portugal, which are members of the EU and whose laws must comply
with EU Directives, these countries have not generally liberalized their
telecommunications sector. We cannot assure you that they will do so in a timely
manner or at all. In addition, the terms and




                                       16
<PAGE>   17

conditions of our licenses, authorizations or registrations may limit or
otherwise affect our scope of operations. We cannot assure you that (1) we will
be able to obtain, maintain or renew licenses, authorizations or registrations
to provide the services we currently provide and plan to provide, (2) such
licenses, authorizations or registrations will be issued or renewed on terms or
with fees that are commercially viable, or (3) the licenses, authorizations or
registrations required in the future can be obtained by us. The loss of, or
failure to obtain, these licenses, authorizations or registrations or a
substantial limitation upon the terms of these licenses, authorizations or
registrations could have a material adverse effect on us.

INTERNET PROTOCOL TRANSPORT SERVICES

     At present there is no general consensus on the regulatory position of
Internet protocol transport services in Europe and the United States. Currently,
Internet protocol transport services are generally treated as unregulated or, in
some European countries, as a telecommunications service subject to minimal
regulatory requirements. We cannot assure you that Internet protocol transport
services will not be regulated in the future in Europe or the United States. We
will continue to monitor regulatory developments that may affect Internet
protocol transport services' operations.

DATA- AND WEB-HOSTING

     The laws relating to the regulation and liability of companies providing
Web-hosting services in relation to the information carried or disseminated
through their services are in the process of development in Europe. In England,
for example, a recent court decision held an Internet service provider liable
for certain allegedly defamatory content carried through its network under
factual circumstance in which the Internet service provider had been notified by
the complainant about the message which the Internet service provider had failed
to delete when asked to do so by the complainant. Decisions, laws regulation and
content liability may significantly affect the services we intend to offer. We
will continue to monitor the developments that may affect these services.

CERTAIN CONSIDERATIONS GENERALLY APPLICABLE TO OUR COMPANY

COMPETITORS WITH GREATER RESOURCES MAY ADVERSELY AFFECT OUR REVENUES

     We compete with various telecommunications companies, including MCI
WorldCom, Inc., Viatel, Inc., KPN Qwest B.V., COLT Telecom Group plc, Level 3
Communications, Inc., Carrier1 International S.A., Deutsche Telekom AG, France
Telecom S.A., Global Crossing Ltd. and British Telecommunications plc. Some of
these entities have announced plans to construct, have begun to construct or are
operating high bandwidth fiber optic networks across various European countries
and in several European metropolitan markets and in some cases, providing
transatlantic connectivity, which do or will compete with our network and our
planned intracity fiber networks. In addition, a number of telecommunications
companies and Internet service providers have begun offering or announced their
intentions to offer data- and Web-hosting services in key European cities.

     We compete primarily on the basis of the range and quality of services
offered, customer service and price. Competitors may force us to lower our
prices or modify our service offerings to remain competitive. We cannot assure
you that we will be able to effectively market our expanded service offerings,
keep prices at a profitable level or attract and retain customers. Many
competitors have established customer bases and extensive brand name recognition
and have greater financial, management and other resources.

     The ongoing liberalization of the European telecommunications market has
coincided with technological innovation to create an increasingly competitive
market, characterized by still-dominant incumbent telecommunications operators
as well as an increasing number of new market entrants. In addition, these
carriers own and operate fully built networks and infrastructure which provide
them with significant cost advantages. Since we utilize these networks in part
to provide many of our services, our failure to gain economical access to these
networks could have a material adverse effect on our business, results of
operations and financial condition.

WE ANTICIPATE THAT PRICES FOR FIBER ASSETS AND BANDWIDTH SERVICES WILL CONTINUE
TO DECLINE

     We anticipate that prices for network transmission capacity will continue
to decline over the next several years due primarily to the following:

     o    price competition as various network providers complete construction
          of networks that might compete with our network;

     o    installation by us and our competitors of excess fiber capacity; and

     o    recent technological advances that permit substantial increases in the
          transmission capacity of both new and existing fiber optic networks.



                                       17
<PAGE>   18

     These and other factors could create pressure on us to reduce our prices.
If we do not continue to introduce product and service enhancements or if there
are no increases in volume and reductions in cost in the services we now provide
to offset these lower prices, our future gross margins will decrease.

OUR COMPETITIVE POSITION MAY BE COMPROMISED BY OUR DEPENDENCE ON LOCAL ACCESS
PROVIDERS

     We need to enter into agreements with local access providers operating in
our target markets. We may also need to enter into agreements which permit us to
place our equipment at the facilities of such local access providers and/or
lease telecommunications transport capacity from such local access providers. We
cannot assure you that we will be able to enter into these agreements on
satisfactory terms.

     EUROPEAN USE OF THE INTERNET, ELECTRONIC COMMERCE, DATA TRANSMISSION
SERVICES, MULTIMEDIA AND OTHER BANDWIDTH INTENSIVE APPLICATIONS MAY NOT INCREASE
AS WE EXPECT

     Our business plan assumes that European use of the Internet, electronic
commerce, data transmission services, multimedia and other bandwidth-intensive
applications will increase substantially in the next few years, in a manner
similar to the increased use in the United States market in the past few years.
If the use of data transmission services, multimedia and bandwidth-intensive
applications in Europe does not increase as we anticipate, demand for many of
our value added products and services, including managed bandwidth services,
Internet protocol transit services and data- and Web-hosting services, will be
lower than we currently anticipate. Reduced demand for our services will have a
negative effect on our pricing power and our financial condition.

WE MAY EXPERIENCE A POTENTIAL LACK OF CUSTOMER DEMAND

     Although we have been delivering services to a number of customers and have
experienced demand for services in the past, we cannot assure you that customer
demand for services over our network will continue to grow. Further, we cannot
assure you that there will be enough customer demand to realize the anticipated
cash flow, operating efficiencies and cost benefits of our network.

SUBSTANTIAL ADDITIONAL CAPITAL IS REQUIRED TO EXPAND OUR NETWORK

     We will require significant amounts of capital to develop and expand our
network. We expect to incur between $500.0 million to $600.0 million through
2000 in additional capital expenditures, including capital lease obligations, to
expand the reach and capacity of our network and deploy intracity fiber networks
and data-and Web-hosting centers in our target metropolitan markets. We believe
that the net proceeds that we received from our offering of senior notes in
fourth quarter 1999, combined with existing cash balances and projected
internally generated funds, will be sufficient to fund our future capital
expenditures through at least December 31, 2000, as well as payments on the
long-term fiber lease arrangements. However, the actual amount and timing of our
future capital requirements may differ from our estimates. Thus, additional
financing may be needed to expand the reach and capacity of our network and to
deploy our intracity fiber networks and data- and Web-hosting. We cannot assure
you that such additional financing will be available on terms acceptable to us
or at all. If we fail to obtain this financing, we might have to delay or
abandon our plans for expanding the reach and capacity of our network and
deploying our intracity fiber networks and data- and Web-hosting centers.
Delaying or abandoning these plans could have a negative effect on our financial
condition.

OUR ACTUAL COSTS AND REVENUES MAY VARY FROM WHAT WE EXPECT THEM TO BE

     Our revenues and the costs of expanding the reach and capacity of our
network, deploying our intracity fiber networks and data- and Web-hosting
centers and operating our business depend upon a variety of factors, including
our ability to:

     o    efficiently manage the enhancement of our network and operations;

     o    negotiate favorable contracts with suppliers;

     o    obtain additional licenses, regulatory approvals, rights-of-way and
          infrastructure contracts;

     o    access markets and attract a sufficient number of customers; and

     o    provide and develop services to which our customers will subscribe.


                                       18
<PAGE>   19


Our revenues and costs are also dependent upon factors that are not within our
control, including:

     o    regulatory changes;

     o    changes in technology;

     o    increased competition;

     o    strikes;

     o    weather; and

     o    performance by third-parties, including our vendors, infrastructure
          providers and customers, in connection with the enhancement of our
          network.

Due to the uncertainty of these factors, our actual costs and revenues may vary
from what we expect them to be and our future capital requirements might
increase. Accordingly, we cannot assure you that the amount of funds required to
enhance our network and deploy our intracity fiber networks and data- and
Web-hosting centers will not be greater than anticipated. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

WE MAY ENCOUNTER DELAYS IN IMPLEMENTING KEY ELEMENTS OF OUR BUSINESS STRATEGY

     Our ability to achieve our strategic objectives will depend in large part
on the successful, timely and cost-effective realization of numerous elements of
our business plan, including:

     o    our plan to develop and offer seamless connectivity between Europe and
          the United States;

     o    our plan to construct intracity fiber networks in up to thirteen major
          European cities by year-end 2001;

     o    our plan to offer data- and Web-hosting centers;

     o    the execution of agreements with various parties regarding, among
          other things, rights-of-way, lease of dark fiber and development and
          maintenance of infrastructure and equipment;

     o    the timely performance by third parties of their contractual
          obligations to engineer, design and construct the infrastructure
          underlying our intracity fiber networks, the extension of our network
          and the planned additional transatlantic capacity that we have
          purchased from the FLAG Atlantic-1 joint venture; and

     o    activation of full capacity on the FLAG Atlantic-1 transatlantic cable
          could be delayed or prevented if the FLAG Atlantic-1 joint venture
          fails to comply with interest coverage and other financial ratios in
          the credit facility it has entered into to finance construction of the
          cable.

     We cannot assure you that we will execute such actions. In addition, any
delays in concluding such agreements would materially and adversely affect the
timely or successful realization of our business plan.

     We believe that our cost estimates and the build-out schedule are
reasonable with respect to these projects. However, the actual construction
costs or time required to complete the plans could substantially exceed current
estimates. Any significant delay or increase in the costs to develop such plans
could have a material adverse effect on our operations.

WE HAVE A LIMITED OPERATING HISTORY AND HAVE SUSTAINED SUBSTANTIAL NET LOSSES

     We have a limited operating history and have historically sustained
substantial operating and net losses. We cannot assure you that our operations
will sustain profitability or positive cash flow in the future. Our operations,
infrastructure and customer base have grown significantly in the last three
years as we have expanded into new European markets. In addition, we intend to
enter additional European markets and offer new telecommunications services. You
should evaluate our prospects in light of the risks, costs and time constraints
that we face in establishing operations and introducing new telecommunications
services in newly liberalizing markets.



                                       19

WE ARE DEPENDENT ON THIRD PARTIES FOR CONSTRUCTING OUR INTRACITY FIBER NETWORKS
AND EXTENDING OUR NETWORK

     Our ability to achieve our strategic objectives will depend in part on our
successful, timely and cost-effective deployment of our intracity fiber networks
and extension of our network. The development of our intracity fiber networks
and extension of our network may be adversely affected by a variety of factors.
Many of these factors, such as the regulatory environment, strikes, natural
disasters and other casualties, are beyond our control. In addition, we will
need to negotiate and conclude agreements with various parties. These agreements
are necessary to establish rights-of-way and to develop and maintain our
infrastructure and equipment.

     For development of the intracity fiber networks and extension of our
network to be successful we need to obtain and maintain a number of agreements,
including:

       o  additional long-term leases of dark fiber;

       o  rights-of-way and other permits from railroads, utilities,
          governmental authorities, transit authorities and private landowners
          to install fiber optic cable; and

       o  rights of access to buildings, such as Internet protocol exchange
          points, that we intend to link to our intracity fiber networks.

     We cannot assure you that we will be able to maintain all of our existing
agreements, rights and permits or that we will be able to obtain and maintain
the additional agreements, rights and permits needed to extend our network and
deploy our intracity fiber networks on acceptable terms. In addition, we may not
be able to conclude such agreements, rights or permits on time. Any delay in
concluding or failure to conclude or maintain these agreements could adversely
affect the operation and/or expansion of our network. This, in turn, could have
a negative effect on our financial condition.

     The successful and timely completion of our intracity fiber networks and
extension of our network will also depend on, among other things:

       o  the timely performance of independent contractors hired to engineer,
          design and construct portions of our intracity fiber networks and core
          network; and

       o  our ability to obtain and maintain applicable government approvals to
          build and operate our intracity fiber networks and extend our network.

     Development of our intracity fiber networks and extension of our network
might cost more or take longer than our current estimates. Although we believe
that our cost estimates and schedule are reasonable, we cannot assure you that
the actual construction costs or time required to construct our intracity
networks and extend our network will not be greater than we currently expect.
Delays or increased costs in developing the intracity networks or extending our
network could have a negative effect on our financial condition.

WE MAY EXPERIENCE ADDITIONAL RISKS AS A RESULT OF EXPANDING OUR NETWORK INTO THE
UNITED STATES

     Our strategy includes expanding our network into select cities in the
United States. The following are particular risks we may experience as a result
of expanding our network into the United States:

       o  we may not be able to obtain leases on intercity and intracity dark
          fiber in our target markets in the United States on favorable terms,
          if at all;

       o  we may not be able to successfully compete with U.S. service
          providers;

       o  complying with applicable U.S. laws and regulations, including tax
          laws and industry related regulations, could be burdensome or
          expensive; and

       o  if there are delays in the commencement of services on the FLAG
          Atlantic-1 transatlantic fiber optic link, we may incur additional
          costs as a result of having to lease additional transatlantic capacity
          from third party providers.

     We cannot assure you that we will be successful in overcoming these risks
or any other problems arising because of our expansion into the United States.


                                       20
<PAGE>   21

WE MAY NOT BE ABLE TO UPGRADE OR EXPAND THE REACH AND CAPACITY OF OUR NETWORK TO
MEET THE EVOLVING DEMANDS OF OUR CUSTOMERS OR THE TECHNOLOGICAL ADVANCES BY
COMPETITORS

     We anticipate that future expansions and adaptions of our network's
infrastructure, including the electronic and software components used in the
infrastructure, may be necessary in order to respond to growth in the number of
customers served, increased demands to transmit larger amounts of data, changes
in our customers' service requirements and technological advances by
competitors. Our ability to expand the reach and capacity of our network may
depend on our continued ability to lease dark fiber or bandwidth at a cost which
allows us to offer bandwidth at attractive prices for our customers. The
expansion and adaptation of our network will require substantial financial,
operational and managerial resources. We cannot assure you that we will be able
to expand or adapt our network to meet the evolving standards, demands and
requirements of our customers or advances of our competitors on a timely basis,
at a commercially reasonable cost, if at all. We also cannot assure you that we
will be able to deploy successfully an expanded and adapted network
infrastructure or that we will have access to capital to realize these goals.
Any failure to expand or adapt our network to the needs of our customers could
have a material adverse effect on our financial condition and results of
operations.

OUR BUSINESS WILL SUFFER IF WE LOSE KEY PERSONNEL OR FAIL TO ATTRACT AND RETAIN
OTHER QUALIFIED PERSONNEL

     Our operations are managed by a small number of key executive officers. The
loss of any of these officers could have a negative effect on our business. The
loss of senior management or the failure to recruit additional qualified
personnel in the future could significantly impede our financial plans, network
development, marketing and other objectives. Although we have designed incentive
and compensation programs to retain key employees and have entered into
employment agreements with certain executive officers, we cannot assure you as
to the continued availability of qualified key executive officers.

     We believe that our growth and future success will depend in large part on
our continued ability to attract and retain highly skilled and qualified
management, marketing, technical and sales executives and other personnel who
are in high demand and often have multiple employment options. The competition
for qualified management, marketing, technical and sales executives and other
personnel in the telecommunications industry is intense. We may lose key
employees or be forced to increase their compensation. We cannot assure you that
we will be able to hire or retain necessary personnel.

WE MAY ENCOUNTER DELAYS, OPERATIONAL PROBLEMS AND INCREASED COSTS IF WE ARE
UNABLE TO ACQUIRE KEY EQUIPMENT FROM OUR MAJOR SUPPLIERS

     We are significantly dependent on the technology and equipment which we
acquire from telecommunications equipment manufacturers that may provide vendor
financing for, and maintenance of, this equipment. Without this equipment, we
would face delays, operational disruption and higher expenses. Our main
equipment suppliers are Alcatel, CIENA, Cisco Systems and Nortel Networks. While
we could obtain equipment of comparable quality from several alternative
suppliers, we may be unable to acquire compatible equipment from such
alternative sources on a timely and cost-efficient basis.

WE MAY FACE DIFFICULTIES IN INTEGRATING, MANAGING AND OPERATING NEW TECHNOLOGY

     Our operations depend on our ability to successfully integrate new and
emerging technologies and equipment. These include the technology and equipment
required for dense wavelength division multiplexing and Internet protocol
transmission using dense wavelength division multiplexing technology.
Integrating these new technologies could increase the risk of system failure.
Additionally, any damage to our network management center could harm our ability
to monitor and manage the network operations.

THE TECHNOLOGY OF OUR NETWORK COULD BECOME OBSOLETE

     The telecommunications industry is subject to rapid and significant changes
in technology and such technological advances may reduce the relative
effectiveness of existing technology and equipment. The cost of implementation
of emerging and future technologies could be significant.

     Development and operation of our network are also subject to certain
technological risks. Our network has been designed to utilize dense wavelength
division multiplexing and synchronous digital hierarchy technology. While the
current operational network segment has performed at or above design
specifications since November 1996, there can be no assurance that our network
will achieve the technical specifications for which we designed it or that we
will be able to upgrade our network as technological improvements in
telecommunications equipment are introduced.





                                       21
<PAGE>   22

IF WE EXPERIENCE SYSTEM FAILURE OR SHUTDOWN, WE MAY NOT BE ABLE TO DELIVER
SERVICES

     Our success depends on our ability to deliver uninterrupted high quality
network services and reliable, high-speed access to the Internet. Our network
and our Internet backbone network are, and our intracity networks and data- and
Web-hosting centers will be, vulnerable to damage or cessation of operations
from:

     o    fire;

     o    earthquakes;

     o    severe storms;

     o    power loss;

     o    natural disasters;

     o    damage from human error and tampering;

     o    software defects;

     o    capacity limitations;

     o    breaches of security;

     o    physical break-ins;

     o    intentional acts of vandalism;

     o    telecommunications failures; and

     o    other factors that can cause interruptions in service or reduced
          capacity for our customers.

We have designed our network to minimize the risk of such system failure but we
cannot assure that we will not experience failures or shutdowns relating to
individual points of presence or even catastrophic failure of the entire
network. Such significant or prolonged system failures or shutdowns could damage
our reputation and result in the loss of customers.

ALTHOUGH WE HAVE IMPLEMENTED NETWORK SECURITY MEASURES, OUR NETWORK MAY BE
SUSCEPTIBLE TO VIRUSES, BREAK-INS OR DISRUPTIONS

     We have implemented many network security measures, such as limiting
physical and network access to our routers. Nonetheless, our network's
infrastructure is potentially vulnerable to computer viruses, break-ins and
similar disruptive problems caused by our customers or other Internet users.
Computer viruses, break-ins or other problems caused by third parties could lead
to interruptions, delays or cessation in service to our customers. Furthermore,
such inappropriate use of the Internet by third parties could also potentially
jeopardize the security of confidential information stored in the computer
systems of our customers. This could, in turn, deter potential customers and
adversely affect our existing customer relationships.

     Security problems represent an ongoing threat to public and private data
networks. Attacks upon the security of Internet sites and infrastructure
continue to be reported to organizations such as the CERT Coordination Center at
Carnegie Mellon University, which facilitates responses of the Internet
community to computer security events. Addressing problems caused by computer
viruses, break-ins or other problems caused by third parties could have a
material adverse effect on us.

     The security services that we offer in connection with our customers'
networks cannot assure complete protection from computer viruses, break-ins or
other disruptive problems. Although we attempt to limit contractually our
liability in such instances, the occurrence of such problems may result in
claims against us or could have a material adverse effect on our business or
reputation or on our ability to attract and retain customers for our products.
Moreover, until more consumer reliance is placed on security technologies
available, the security and privacy concerns of existing and potential customers
may inhibit the growth of the Internet service industry and our customer base
and revenues.




                                       22
<PAGE>   23

OUR INFRASTRUCTURE MAY NOT KEEP PACE WITH OUR RAPID GROWTH

     Our operating and financial control systems and infrastructure may not be
adequate to maintain and effectively manage future growth. If we fail to
continuously upgrade our administrative, operating and financial control systems
or unexpected expansion difficulties arise resulting from our rapid growth, our
business, results of operations and financial condition could suffer a material
adverse effect. We must also purchase additional telecommunications facilities
and expand, train and manage the employee base. Inaccuracies in our forecasts of
market demand could result in insufficient or excessive telecommunications
facilities and fixed expenses that are not in line with our operations. As we
proceed with our development and expansion, there will be additional demands on
our customer support, sales and marketing and administrative resources and
network infrastructure.

DELAYS IN LIBERALIZATION OF THE EU TELECOMMUNICATIONS MARKET MAY ADVERSELY
AFFECT EXECUTION OF OUR BUSINESS STRATEGY

     A substantial portion of our strategy depends on the timely implementation
of regulatory liberalization of the EU telecommunications market. We may
implement our business plan and make capital expenditures in a given country in
anticipation of regulatory liberalization which may not occur. This
liberalization is occurring in accordance with existing European Commission
directives. Even if an EU member state promptly adopts liberalization measures
in a timely fashion, established national or regional telecommunications
operators, regulators, trade unions and other sources may resist implementing
such measures. Further, our provision of services in Europe and the
implementation of our business plan may be materially adversely affected if any
EU member state imposes greater restrictions on international services between
the EU member state and non-EU countries.

DELAYS IN OBTAINING REGULATORY LICENSES AND APPROVALS COULD ADVERSELY AFFECT OUR
PLANS TO OFFER SERVICES IN OUR TARGETED MARKETS

     Because we plan to provide an expanded array of telecommunications services
in Europe, we will become subject to significant additional regulation at the
EU, national and local levels. In particular, we must obtain additional
agreements for the long-term lease of dark fiber, rights-of-way and other
permits to install fiber optic cable from railroads, utilities and governmental
authorities to expand the geographic reach of the network. We must also apply
for permits and other regulatory approval from government and local authorities
to construct our intracity fiber networks. In addition, we are dependent on FLAG
Atlantic Limited applying for and obtaining the permits and other regulatory
approvals required to build and operate the FLAG Atlantic-1 transatlantic cable
link. We cannot assure you that we or (as to FLAG Atlantic-1) FLAG Atlantic
Limited will be able to obtain or maintain the necessary lease agreements,
regulatory approvals, rights and permits on a timely basis or that we will not
be adversely affected by regulatory developments, which could have a material
adverse effect on these planned businesses. Delays in receiving regulatory
approvals, or the enactment of adverse regulations or regulatory requirements,
may delay or prevent us from expanding the geographic reach of our network or
building out our intracity fiber networks in our targeted markets.

WE MAY BE LIABLE FOR INFORMATION DISSEMINATED THROUGH OUR NETWORK

     The law relating to the regulation and liability of Internet service
providers in relation to information carried or disseminated is developing.

     The EU Commission has prepared a proposal for a directive on certain legal
aspects of electronic commerce, which, if adopted by the European Parliament and
Council, would require member states to make certain changes to national laws.
The proposed directive would apply to us and other service providers established
in the EU and aims to establish a consistent legal framework for electronic
commerce within the EU.

     The proposed directive includes provisions which would limit the liability
(other than for prohibitory injunctions) of "intermediaries" (such as Internet
service providers and carriers that transmit or host information provided by
third party users of the service) in respect of certain access, caching and
hosting services provided by them, subject to compliance with certain
conditions. The limitations potentially limit civil and criminal liability for
all types of illegal activities initiated by third parties on-line (e.g.
copyright piracy, unfair competition practices, misleading advertising,
copyright infringements, defamation, trademark infringements). If an
intermediary fails to qualify for such limitations, the nature and scope of his
liability will be established on the basis of member states' existing
legislation which may not provide us with the same protections from liability.

     The proposed directive is still under review with member states and it is
impossible to predict whether it will eventually be adopted and, if so, in what
form. Decisions, laws, regulations and other activities regarding regulation and
content liability may adversely affect the development and profitability of
companies offering Internet access services, including us.




                                       23
<PAGE>   24

     The imposition upon Internet and Web-hosting service providers of potential
liability for material carried on or disseminated through their systems could
require us to implement measures to reduce our exposure to liability. Such
measures may require that we spend substantial resources or discontinue some
product or service offerings. Any of these actions could have a material adverse
effect on our business, operating results and financial condition.

THERE MAY BE RESTRICTIONS ON OUR ABILITY TO CARRY CERTAIN TRAFFIC THROUGH OUR
NETWORK

     In October 1999, the EU adopted a directive on data protection which
establishes minimum levels of protection for personal information and imposes
limits on the collection, processing, storage and dissemination of such data
without the subject's consent. The directive is being implemented in EU member
states in various stages. Certain functions typically carried out by
telecommunications carriers, including GTS Europe and its carrier customers
(e.g. storage of routing and billing information) are subject to the directive.
The directive forbids the transfer of personal information collected in the EU
to countries that lack "adequate" privacy protection. At the moment, the United
States is not judged to have "adequate" privacy protection. The EU and U.S.
authorities are currently holding discussions aimed at resolving this issue and
enabling the free circulation of personal information between the EU and the
United States. However, if these discussions are not successful, there is a
possibility that the movement of certain types of telecommunications traffic
from the EU to the United States could be disrupted, with consequent impact on
our revenues.

WE MAY BE SUBJECT TO RISKS BASED ON FLUCTUATIONS IN THE VALUE OF FOREIGN
CURRENCY

     As of January 1, 1999, our functional currency is the Euro. Our reporting
currency is the U.S. dollar. Still, we conduct, and will continue to conduct,
business transactions in currencies other than our functional and reporting
currencies; for this reason, appreciation or depreciation in the value of other
currencies as compared to our functional or reporting currency could result in a
material transaction or translation gain or loss to us.

     From time to time, we have entered into hedging transactions to limit our
exposure to foreign currency fluctuations; however, we find it impractical to
protect ourselves against all of this exposure and as a result we will continue
to experience foreign currency gains and losses. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."

WE MAY BE UNABLE TO MEET OUR SUBSTANTIAL DEBT OBLIGATIONS

     We have incurred substantial debt and may incur substantial additional debt
to implement our business plans. We are currently evaluating entering into,
through one of our subsidiaries, a new senior credit facility with one or more
institutional lenders in an aggregate amount of up to $500.0 million.

     Our ability to make principal and interest payments on our debt, will
depend upon, among other things, our future operating performance. Our future
operating performance depends on a variety of factors, many of which are beyond
our control. Because of this uncertainty, we cannot assure you that we will
generate sufficient cash flow to make payments on our debt. Insufficient future
cash flow could impair our ability to raise additional equity or debt financing,
to expand the reach and capacity of our network, and to construct our intracity
fiber networks and data- and Web-hosting centers. Our cash flow could also be
insufficient to make principal and interest payments on our debt. If this
happens, we may be required to renegotiate the terms of, or to refinance, our
long-term debt. We cannot assure you that we would be able to refinance or
renegotiate the terms of our debt when required.

     As a result of our current high level of debt, we:

     o    will need significant cash to service our debt, which will reduce
          funds available for operations, future business opportunities and
          investments in new or developing technologies and make us more
          vulnerable to adverse economic conditions;

     o    may increase our vulnerability to general adverse economic and
          industry conditions;

     o    may not be able to refinance our existing debt or raise additional
          financing to fund future working capital, capital expenditures, debt
          service requirements, acquisitions or other general corporate
          requirements;

     o    may be less flexible in planning for, or reacting to, changes in our
          business and in the telecommunications industry that affect how we
          implement our financing, construction or operating plans; and

     o    will have more debt than some of our competitors, which may place us
          at a competitive disadvantage with respect to such competitors.


                                       24

<PAGE>   25

     If we fail to make the required payments or to comply with our debt
covenants, we will default on our debt. A default would permit our debtholders
to accelerate the maturity of the debt, which in turn could cause defaults under
our other debt.

COVENANTS IN OUR DEBT AGREEMENTS RESTRICT OUR OPERATIONS

     The covenants in our currently outstanding debt may materially and
adversely affect our ability to finance our future operations or capital needs
or to engage in other business activities. Among other things, these covenants
limit our ability to:

     o    incur additional debt;

     o    pay dividends or make certain other restricted payments;

     o    limit our ability to use our assets as collateral for loans;

     o    dispose of our assets;

     o    enter into transactions with affiliates; or

     o    consolidate, merge or sell all or substantially all of our assets and
          the assets of our subsidiaries.

ITEM 2. PROPERTIES

     We own substantially all of the telecommunications equipment required for
our business; however, a substantial part of the fiber is leased on a long-term
basis. Our installed fiber optic cable is laid under the various rights-of-way
held by us. Other fixed assets are located at various leased locations in
geographic areas served by us.

     Our principal administrative offices and our Network Operations Center are
located in two adjacent buildings in Hoeilaart, Belgium, just outside Brussels.
The leases on both the buildings expire on June 30, 2005. One of the buildings
has an option to cancel on January 1, 2022 with a penalty of six months rent. In
addition, we have short-term leases expiring on February 28, 2000 in Rixensart,
Belgium and on September 1, 2000 in Kraainem, Belgium. We have entered into
leases for two additional buildings in the same complex as our principal
offices. These buildings were occupied as of January 2000. The leases run
through January 2009 but may be terminated after six years with six months
notice plus six months rental penalty.

     In addition to the offices in Belgium, we have a leased office space in
Dublin, Ireland, which expires on October 2, 2022, in London, United Kingdom,
which expires in August 2002, in Frankfurt, Germany, which expires in March 2004
and Madrid, Spain, which expires in January 2004. We lease various offices on a
short-term basis for regional sales and service personnel.

ITEM 3. LEGAL PROCEEDINGS

     We are subject to various claims and proceedings in the ordinary course of
our business. In addition, we are party to the following claims and proceedings:

     On March 26, 1999, we opposed the license fee imposed by the French
regulator as, among other things, contrary to Article 11 of EC Directive 97/13
which requires license fees to cover only the administrative cost of managing
the license. On September 23, 1999, the French regulator informed us that they
rejected our position. On November 24, 1999, we filed a complaint before the
French administrative tribunal opposing the license fee. Under French law, we
would not be required to pay the license fee and the French regulator does not
have the right to terminate our license until such time as a ruling by the
French administrative tribunal is issued. If our claim is rejected in a final
non-appealable judgment, we will be required to pay our license fee in France.
We do not believe that the outcome of this litigation will have a material
adverse effect upon our financial condition.

     Based on information currently available, we believe that none of such
current claims or proceedings, individually or in the aggregate, will have a
material adverse effect on our financial condition or results of operations,
although there can be no assurance that this will remain the case.

ITEM 4. SUBMISSION OF MATTERS TO VOTE OF SECURITY HOLDERS

     During the fourth quarter, our shareholders approved by unanimous written
consent:

     o    The resignation of Mr. Bernard McFadden, Mr. Gerald Thames, Mr. Lars
          Larsson, Mr. Joseph Surmont and Mr. Bo Hamnell from the Board of
          Supervisory Directors


                                       25
<PAGE>   26

     o    The appointment of Mr. Mikel Williams to the Board of Supervisory
          Directors

     o    The resignation of Mr. William Seippel and Mr. Grier Raclin from the

ITEM 5. MARKET FOR THE COMPANY'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

     Our common equity is privately held and not traded on any United States or
foreign exchange or market.

     As of February 15, 2000, our common equity was held by eight holders of
record.

     We have not paid any dividend on our common stock and do not intend to pay
dividends in the foreseeable future. In addition, the indentures governing our
11-1/2% senior notes due 2007, 10-3/8% senior notes due 2006, 10-3/8% senior
notes due 2009, 10-1/2% senior notes due 2006 and 11% senior notes due 2009
contain restrictions on the making of restricted payments (in the form of the
declaration of certain dividends or distributions, the purchase, redemption or
other acquisition of any of our capital stock, the payments of principal on any
subordinated indebtedness, as defined in such indentures, prior to any scheduled
payment or maturity, unless (A) no default or event of default, as defined in
the indentures, shall have occurred and be continuing, (B) we are able
immediately after giving effect to such a restricted payment to satisfy an
incurrence of indebtedness test and (C) such restricted payments do not exceed
certain amounts. In addition, we and certain of our operating subsidiaries may
enter into future financings, the terms of which may include dividend
restrictions.

     During the year ended December 31, 1999, we issued stock which was not
registered under the Securities Act of 1933, as amended (the "Securities Act"),
pursuant to the exercise of options to purchase 3,600 shares of our common
stock.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

     The following is a discussion of our financial condition and results of
operations as of December 31, 1999 and 1998 and for the three year period ended
December 31, 1999. The following discussion should be read in conjunction with
our Consolidated Financial Statements and the notes related thereto.

SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

     Certain statements contained in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" including, without limitation,
those concerning (i) projected traffic volume, (ii) future revenues and costs
and (iii) changes in our competitive environment, contain forward-looking
statements concerning our operations, economic performance and financial
condition. Because such statements involve risks and uncertainties, actual
results may differ materially from those expressed or implied by such
forward-looking statements.

     In addition, any statements that express, or involve discussions as to,
expectations, beliefs, plans, objectives, assumptions or future events or
performance (often, but not always, through the use of words or phrases such as
"will likely result," "are expected to," "will continue," "is anticipated,"
"estimated," "intends," "plans," "projection" and "outlook") are not historical
facts and may be forward-looking and, accordingly, such statements involve
estimates, assumptions and uncertainties which could cause actual results to
differ materially from those expressed in the forward-looking statements.
Accordingly, any such statements are qualified in their entirety by reference
to, and are accompanied by, the factors discussed throughout this Report. Among
the key factors that have a direct bearing on our results of operations are the
potential risk of delay in implementing our business plan; the political,
economic and legal aspects of the markets in which we operate; competition and
our need for additional substantial financing. These and other factors are
discussed herein under "Business," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and elsewhere in this Report.

     The factors described in this Report could cause actual results or outcomes
to differ materially from those expressed in any forward-looking statements made
by us or on behalf of us, and investors, therefore, should not place undue
reliance on any such forward-looking statements. Further, any forward-looking
statement speaks only as of the date on which such statement is made, and we
undertake no obligation to update any forward-looking statement or statements to
reflect events or circumstances after the date on which such statement is made
or to reflect the occurrence of unanticipated events. New factors may emerge
from time to time, and it is not possible for management to predict all of such
factors. Further, we cannot assess the impact of each such factor on our
business or the extent to which any factor, or combination of factors, may cause
actual results to differ materially from those contained in any forward-looking
statements.

OVERVIEW

     We are one of the leading European providers of managed bandwidth services
and related telecommunications services to telecommunications carriers, Internet
service providers and other bandwidth-intensive customers. As of December 31,
1999, we operated a centrally managed fiber optic network in Europe over
approximately 16,200 kilometers connecting 27 cities in 11 European countries,
with service to the United States provided through capacity leased on
transatlantic cables. On June 24, 1998, we acquired a 75% interest in Ebone A/S
("Ebone"). Ebone operates a Tier-1 Internet backone network that connects
European Internet service providers to the Internet. We purchased the remaining
25% interest in Ebone on May 25, 1999. The results of Ebone have been included
in the accompanying consolidated financial statements from the date of
acquisition.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1999 VS. DECEMBER 31, 1998

     Revenue. Our consolidated revenue for the year ended December 31, 1999 was
$304.4 million as compared to $85.3 million for the comparable period in 1998.
The growth in revenue is attributable to the continued deployment of our network
and increased customer base.

     Telecommunication Services. Our telecommunication services costs for the
year ended December 31, 1999 were $92.0 million, or 30.2% of revenue, compared
to $41.8 million, or 49.0% of revenue, for the comparable period in 1998. The
increase in telecommunication services for the year ended December 31, 1999
primarily due to increased costs related to operating and maintaining the
network as it continues to be deployed, as well as the increase in local access
costs resulting from increased volume of traffic.



                                       28
<PAGE>   29

     Selling, General and Administrative. Selling, general and administrative
expenses for the year ended December 31, 1999 were $50.9 million, or 16.7% of
revenue, as compared to $28.3 million, or 33.2% of revenue, for the comparable
period in 1998. The increase in selling, general and administrative expenses is
reflective of the growth of our business operations and support personnel. At
December 31, 1999, we had 450 employees as compared to 265 employees at December
31, 1998.

     Depreciation and Amortization. Depreciation and amortization expense for
the year ended December 31, 1999 was $68.7 million as compared to $28.6 million
in 1998. The increase in depreciation and amortization expense is attributable
to depreciation of additional network assets due to the continued build-out of
our network.

     Interest. Interest expense for the year ended December 31, 1999 was $81.1
million as compared to $30.9 million for the comparable period in 1998. The
increase was primarily attributable to the interest and related costs associated
with the issuance in January 1999 of $200 million aggregate principal amount of
10-3/8% senior notes due 2009 ("Senior Notes due 2009") and $85 million
aggregate principal amount of 10-3/8% senior notes due 2006 ("Senior Notes due
2006") and the issuance in November 1999 of $225 million aggregate principal
amount of 10-1/2% senior notes due 2006 ("New Senior Notes due 2006") and $275
million aggregate principal amount of 11% senior notes due 2009 ("New Senior
Notes due 2009").

     Interest income, included in other income/(expense), for the year ended
December 31, 1999 was $28.7 million as compared to $10.0 million for the
comparable period in 1998. The increase in interest income was the result of
investing the excess cash generated from the issuance of the senior notes in
January and November 1999 in various highly liquid investments.

     Foreign Currency Losses. Foreign currency losses were minimal for the year
ended December 31, 1999 as compared to $11.3 million for the comparable period
in 1998. The losses in 1998 were primarily the result of foreign exposure from
the issuance of the senior notes in U.S. dollars and other U.S. dollar cash and
payables balances, the weakening of the dollar versus European currencies in the
third and fourth quarter and losses on several forward exchange contracts.

YEAR ENDED DECEMBER 31, 1998 VS. DECEMBER 31, 1997

     Revenue. Our consolidated revenue for the year ended December 31, 1998 was
$85.3 million as compared to $5.4 million for the comparable period in 1997. The
growth in revenue is attributable to the continued deployment of our network as
well as the inclusion of Ebone, which had revenue of $17.7 million for the
period from the date of acquisition through December 31, 1998.

     Telecommunication Services. Our telecommunication services costs for the
year ended December 31, 1998 were $41.8 million, or 49.0% of revenue, compared
to $6.8 million, or 125.9% for the comparable period in 1997. The increase in
cost of revenue for the year ended December 31, 1998 was primarily due to
increased costs related to operating and maintaining the network as it is
continued to be deployed, as well as the increase in local access costs.

     Selling, General and Administrative. Selling, general and administrative
expenses for the year ended December 31, 1998 were $28.3 million, or 33.2% of
revenue, as compared to $17.9 million, or 331.5% of revenue, for the comparable
period in 1997. The increase in selling, general and administrative expenses is
reflective of the growth of our business operations and support personnel as the
number of employees grew to 265 at December 31, 1998 from 130 at December 31,
1997.

     Depreciation and Amortization. Depreciation and amortization expense for
the year ended December 31, 1998 was $28.6 million as compared to $5.2 million
in 1997. The increase in depreciation and amortization expense is attributable
to depreciation of additional network assets due to the continued build-out of
our network.

     Interest. Interest expense for the year ended December 31, 1998 was $30.9
million as compared to $12.8 million for the comparable period in 1997. The
increase was primarily the result of incurring a full year of interest and
related costs associated with our issuance in August 1997 of $265.0 million
aggregate principal amount of 11-1/2% Senior Notes due 2007 (the "Senior Notes
due 2007") in 1998 as compared to only five months of interest and costs in
1997.

     Interest income, included in other income/(expense), for the year ended
December 31, 1998 was $10.0 million as compared to $6.6 million for the
comparable period in 1997. The increase in interest income was the result of
investing the excess cash generated from the issuance of the Senior Notes due
2007 in various highly liquid investments.

Foreign Currency Losses. Foreign currency losses were $11.3 million for the year
ended December 31, 1998 as compared to $0.4 million for the comparable period in
1997. The losses in 1998 were primarily the result of foreign exposure from the
issuance of the Senior Notes due 2007 in U.S. dollars and other U.S. dollar cash
and payables balances, the weakening of the dollar versus European currencies in
the third and fourth quarter and losses on several forward exchange contracts.



                                       29
<PAGE>   30

LIQUIDITY AND CAPITAL RESOURCES

     In January 1999, we issued $200 million aggregate principal amount of
10-3/8% senior notes due 2009 ("Senior Notes due 2009") and $85 million
aggregate principal amount of 10-3/8% senior notes due 2006 ("Senior Notes due
2006"). In November 1999, we issued $225 million aggregate principal amount of
10-1/2% senior notes due 2006 ("New Senior Notes due 2006") and $275 million
aggregate principal amount of 11% senior notes due 2009 ("New Senior Notes due
2009").

     Development of our network has been capital intensive. We currently expect
that we will incur through December 31, 2000, between $500.0 million to $600.0
million in capital expenditures, including capital lease obligations, to expand
the reach and capacity of our network, and to construct intracity fiber networks
and data- and Web-hosting centers in our target metropolitan markets. We believe
existing cash balances and our projected internally generated funds, should be
sufficient to fund our currently identified capital expenditures, at least
through December 31, 2000, including payments on the long-term fiber lease
arrangements. However, the actual amount and timing of our future requirements
may differ materially from our estimates. Any failure to obtain necessary
financing may require that we delay or abandon our plans for expanding the reach
and capacity of our network, and constructing our planned intracity fiber
networks and data- and Web-hosting centers which could jeopardize our viability.

     We are currently evaluating entering into, through a wholly owned
subsidiary, a new credit facility (the "New Credit Facility") with one or more
institutional lenders in an aggregate amount of up to $500 million in the first
quarter of 2000. The New Credit Facility would be used for the development of
our network.

     We had a positive working capital of $563.9 million and $70.7 million as of
December 31, 1999 and 1998, respectively. We had cash and cash equivalents of
$565.4 million and $130.1 million at December 31, 1999 and 1998, respectively.
We had $18.4 million and $30.1 million of restricted cash at December 31, 1999
and 1998, respectively. The restricted cash at December 31, 1999 primarily
relates to cash held in escrow for bank guarantees issued in connection with
fiber and office leases associated with the Rabo Facility. The restricted cash
at December 31, 1998 primarily represents our obligation to place into escrow
the first four scheduled semi-annual interest payments on the Senior Notes due
2007.

     During the year ended December 31, 1999, we provided $102.7 million cash
from operating activities compared with providing $45.0 million for the
comparable period in 1998. Investing activities used cash of $395.3 million for
the year ended December 31, 1999 as compared to using cash of $92.8 million for
the comparable period in 1998.

     We have developed risk management policies that establish guidelines for
managing foreign exchange risk. We continuously evaluate the materiality of
foreign exchange exposures in different countries and the financial instruments
available to mitigate this exposure. We have designed reporting processes to
monitor the potential exposure on an ongoing basis. We have limited our foreign
currency exposure by entering into a foreign currency swap agreement. We find it
impractical to hedge all foreign currency exposure and as a result, will
continue to experience foreign currency gains and losses.

YEAR 2000 COMPLIANCE

We initiated a Year 2000 compliance program during 1998 to address the risks
associated with the Year 2000 issue and to avoid material loss or impact to us
or our customers due to these risks. We experienced no material problems
relating to the Year 2000 issues. We incurred approximately $0.9 million in
costs, $0.7 million of which we incurred during 1999, to ensure that business
would continue without incident after December 31, 1999. We are continually
monitoring all of our systems; however, we believe that any and all additional
Year 2000 issues or concerns that may arise will be addressed and corrected by
March 31, 2000.

INTRODUCTION OF THE EURO

     On January 1, 1999, eleven of the fifteen member countries of the European
Union, including Belgium, The Netherlands, Ireland, France, Germany, Italy and
Spain, where we have our headquarters and the majority of our subsidiaries and
operations, established fixed conversion rate between their existing sovereign
currencies and a new currency called the "Euro." These countries adopted the
Euro as their common legal currency on that date. The Euro trades on currency
exchanges and is available for non-cash transactions. Hereafter and until
January 1, 2002, the existing sovereign currencies will remain legal tender in
these countries. On January 1, 2002, the Euro is scheduled to replace the
sovereign legal currencies of these countries.

     We have significant operations within the European Union including many of
the countries that have adopted the Euro. We continue to evaluate the impact the
Euro will have on our continuing business operations and no assurances can be
given that the Euro will not have material adverse affect on our business,
financial condition and results of operations. However, we do not expect the
Euro to have a material effect on our competitive position as a result of price
transparency within the European Union as we have always operated as a
pan-European business with transparent pricing in ECU for the majority of our
customers. Moreover, we have



                                       30
<PAGE>   31
evaluated our ability to update our information systems to accommodate the
adoption of the Euro and we do not expect to incur material costs in the
updating of such systems. In addition, we cannot accurately predict the impact
the Euro will have on currency exchange rates or on our currency exchange risk.

     We adopted the Euro as our functional currency on January 1, 1999.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     Our treasury function manages our funding, liquidity, and exposure to
interest rate and foreign exchange rate risks. Our treasury operations are
conducted within a framework of policies and guidelines authorized by our Board
of Directors. In accordance with our policy, we do not enter into any
transactions of a speculative nature.

     We are exposed to market risk from changes in interest rates on long-term
obligations and as a global company, we also face exposure to adverse movements
in foreign currency exchange rates. A portion of our debt obligations are
denominated in currencies which expose us to risks associated with changes in
foreign exchange rates. We have developed risk management policies that
establish guidelines for managing foreign exchange risk and periodically
evaluate the materiality of foreign exchange exposures and the financial
instruments available to mitigate this exposure.

     We have entered into a foreign currency swap agreement in order to mitigate
our exposure on some of our US dollar denominated debt. We also attempt to
mitigate this and other exposures from debt obligations denominated in exposed
currencies by maintaining assets in the exposed currency wherever possible. We
find it impractical to hedge all foreign currency exposure and as a result will
continue to experience foreign currency gains and losses. The introduction of
the Euro as a common currency for members of the European Union occurred on
January 1, 1999. We have not determined what impact, if any, the Euro will have

             REPORT OF ERNST & YOUNG REVISEURS D'ENTREPRISES S.C.C.
                              INDEPENDENT AUDITORS

To the Board of Directors and the Shareholders of Global TeleSystems Europe B.V.

     We have audited the accompanying consolidated balance sheets of Global
TeleSystems Europe B.V. as of December 31, 1999 and 1998, and the related
consolidated statements of operations, cash flows, and shareholders' equity for
each of the three years in the period ended December 31, 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Global
TeleSystems Europe B.V. at December 31, 1999 and 1998, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1999, in conformity with accounting principles
generally accepted in the United States.

                         GLOBAL TELESYSTEMS EUROPE B.V.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: NATURE OF BUSINESS OPERATIONS

     Global TeleSystems Europe B.V. ("the Company", formerly Hermes Europe
Railtel B.V.) is one of the leading European providers of managed bandwidth
services and related telecommunications services to telecommunications carriers,
Internet service providers and other bandwidth-intensive customers. The Company
operates a centrally managed fiber optic network (the "Network") in Europe
connecting various cities with service to the United States provided through
capacity leased on transatlantic cables. In addition, the Company operates a
Tier 1 Internet backbone network that connects European service providers to the
Internet.

     The Company was formed on July 6, 1993 and is 98.4% owned by GTS Carrier
Services, Inc., a wholly owned subsidiary of Global TeleSystems Group, Inc.
("GTS"), a leading independent provider of telecommunications services to
businesses, other high usage customers and telecommunications carriers in
Europe, Russia and the Commonwealth of Independent States.

     For financial reporting purposes, the Company has reflected the accounting
acquisition effect of the incremental purchases, by GTS Carrier Services, Inc.,
from 1993 through 1999, of the Company's common shares, that were held by
nonaffiliated entities of GTS. Accordingly, the Company's consolidated financial
statements have been retroactively restated for all periods presented to reflect
the acquisition accounting effect, a process generally referred to as "push
down" accounting. The cumulative effect, through December 31, 1999, of the
allocation of the purchase price paid by GTS Carrier Services, Inc. has resulted
in goodwill of approximately $228.8 million, which is being amortized on a
straight-line basis over the estimated useful lives, generally twenty years.

NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of Global
TeleSystems Europe B.V. and all wholly-owned subsidiaries. All significant
intercompany accounts and transactions are eliminated upon consolidation.
Results of subsidiaries acquired and accounted for by the purchase method have
been included in operations from the relevant date of acquisition.

RECLASSIFICATIONS

     Certain reclassifications have been made to the 1998 and 1997 consolidated
financial statements in order to conform to the 1999 presentation.

CASH AND CASH EQUIVALENTS

     The Company classifies cash on hand and deposits in banks, including
commercial paper, money market accounts and any other investments with an
original maturity of three months or less, that the Company may hold from time
to time, as cash and cash equivalents. The Company had $18.4 million and $30.1
million of restricted cash at December 31, 1999 and 1998, respectively. The
restricted cash is primarily related to cash held in escrow for bank guarantees
in 1999 and for interest payments in 1998.

PROPERTY AND EQUIPMENT

     Property and equipment is stated at cost. Depreciation, which includes the
amortization of assets recorded under capital leases, is calculated on a
straight-line basis over the lesser of the estimated lives ranging from five to
ten years for communications equipment and five to ten years for furniture,
fixtures and equipment and other property, or their contractual term.
Construction in process, which is currently related to the configuration and
buildout of the network, is transferred to communications equipment as
construction is completed and/or equipment is placed in service. Depreciation is
recorded commencing with the first full month that assets are placed into
service. Maintenance and repairs are charged to expense as incurred.

     In accordance with Statement of Financial Accounting Standards ("SFAS") No.
34, "Capitalization of Interest Costs," the Company capitalizes material
interest costs associated with the construction of capital assets for business
operations and amortizes the costs over the assets' useful lives. The Company
capitalized $13.0 million and $4.9 million of interest costs in 1999 and 1998,
respectively. The Company did not capitalize any interest in 1997.





                                       38
<PAGE>   39

GOODWILL AND INTANGIBLE ASSETS

     Goodwill represents the excess of acquisition costs over the fair market
value of the net assets of acquired businesses and is being amortized on a
straight-line basis over the estimated useful lives, generally twenty years.
Intangible assets, primarily deferred financing costs and licenses are amortized
on a straight-line basis over the lesser of their estimated useful lives or
their contractual term, generally three to ten years. In accordance with APB 17,
"Intangible Assets," the Company continues to evaluate the amortization period
to determine whether events or circumstances warrant revised amortization
periods. Additionally, the Company considers whether the carrying value of such
assets should be reduced based on the future benefits of its deferred financing
costs.

LONG-LIVED ASSETS

     In accordance with SFAS No. 121, long-lived assets to be held and used by
the Company are reviewed to determine whether any events or changes in
circumstances indicate that the carrying amount of the asset may not be
recoverable. For long-lived assets to be held and used, the Company bases its
evaluation on such impairment indicators as the nature of the assets, the future
economic benefit of the assets, any historical or future profitability
measurements, as well as other external market conditions or factors that may be
present. If such impairment indicators are present or other factors exist that
indicate that the carrying amount of the asset may not be recoverable, the
Company determines whether an impairment has occurred through the use of an
undiscounted cash flow analysis of assets at the lowest level for which
identifiable cash flows exist. If an impairment has occurred, the Company
recognizes a loss for the difference between the carrying amount and the
estimated value of the asset. The fair value of the asset is measured using
quoted market prices or, in the absence of quoted market prices, fair value is
based on an estimate of discounted cash flow analysis. Based on its analysis for
the years ended December 31, 1999 and 1998, the Company determined that there
was not an impairment of its long-lived assets.

INCOME TAXES

     The Company uses the liability method of accounting for income taxes.
Deferred income taxes result from temporary differences between the tax basis of
assets and liabilities and the basis as reported in the consolidated financial
statements. Deferred taxes are reflected net of permanent differences for
pushdown accounting adjustments.

FOREIGN CURRENCY TRANSLATION

     The Company follows a translation policy in accordance with SFAS No. 52,
"Foreign Currency Translation," (as amended by SFAS No. 130, "Reporting
Comprehensive Income"). As of January 1, 1999, the functional currency for the
Company has been the Euro. Prior to January 1, 1999, the functional currency of
the Company was the Belgian franc. In most instances, either the local currency
or the Euro is considered the functional currency for the Company's
subsidiaries. The accounting records of the subsidiaries are remeasured into the
functional currency, consolidated and then translated into U.S. dollars for the
purpose of preparing the accompanying financial statements in accordance with
accounting principles generally accepted in the United States. Assets and
liabilities are translated at the rates of exchange at the balance sheet date.
Income and expense accounts are translated at average monthly rates of exchange.
The resultant translation adjustments are included in accumulated other
comprehensive loss, a separate component of shareholders' equity. Gains and
losses from foreign currency transactions are included in operations.

REVENUE RECOGNITION

     The Company's revenue is associated with its customers' right to use the
Network and is recognized on a straight-line basis over the terms of the
customer contracts. Billings received in advance of service being performed are
deferred and recognized as revenue as the service is performed.

SEGMENT INFORMATION

     The Company adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," as of December 31, 1998. SFAS 131
establishes annual and interim reporting standards for an enterprise's operating
segment and related disclosures about its products, services, geographic areas
and major customers.

     Based on its organizational structure, the Company operates in one
reportable segment providing telecommunications services mainly to businesses
and other organizations located principally in the European Union.

NET LOSS PER SHARE

     Basic and diluted loss per share is calculated in accordance with SFAS No.
128, "Earnings Per Share." The Company's net loss per share calculation (basic
and diluted) is based upon the weighted average common shares issued. Employee
stock options have been excluded from the 1998 and 1997 net loss per share
calculation because their effect would be anti-dilutive. There are no
reconciling items in the numerator of the Company's net income (loss) per share
calculation. The following is a reconciliation of the denominator of the
Company's net income (loss) per share calculation:

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The carrying amounts for cash, accounts receivable, accounts payable, and
accrued liabilities approximate their fair value. The fair value of the
long-term debt is determined based on quoted market rates. The fair value of the
Company's principal fixed rate long-term debt is as follows (in thousands):

OFF BALANCE SHEET RISK AND CONCENTRATION OF CREDIT RISK

     Financial instruments that potentially subject the Company to concentration
of credit risk consist primarily of cash and cash equivalents and accounts
receivable. At December 31, 1999 and 1998, the Company maintained most of its
cash and cash equivalents in high quality U.S. and European financial
institutions. The Company extends credit to various customers and establishes an
allowance for doubtful accounts for specific customers that it determines to
have significant credit risk.

DERIVATIVE FINANCIAL INSTRUMENTS

     The Company has developed risk management policies that establish
guidelines for managing foreign exchange risk and periodically evaluates the
materiality of foreign exchange exposures in different countries and the
financial instruments available to mitigate this exposure. The Company finds it
impractical to hedge all foreign currency exposures and as a result, will
continue to experience foreign currency gains and losses.

     The Company currently accounts for its existing derivative under SFAS No.
52, "Foreign Currency Translation." In June 1999, the FASB issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." The Company
expects to adopt the new statement effective January 1, 2001. The statement will
require the Company to recognize all derivatives on the balance sheet at fair
value. The Company does not anticipate that the adoption of the statement will
have a material effect on its results of operations or financial position.

STOCK BASED COMPENSATION

     SFAS No. 123, "Accounting for Stock-Based Compensation," establishes a fair
value method of accounting for employee stock options and similar equity
instruments. The fair value method requires compensation cost to be measured at
the grant date based on the value of the award and is recognized over the
service period. SFAS No. 123 allows companies to either account for stock-based
compensation under the new provisions of SFAS No. 123 or under the provisions of
APB No. 25, "Accounting for Stock Issued to Employees." The Company has elected
to account for its stock-based compensation in accordance with the provisions of
APB No. 25 and presents pro forma disclosures of net loss as if the fair value
method had been adopted.

USES OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

    The preparation of these consolidated financial statements, in conformity
with generally accepted accounting principles, requires management to make
estimates and assumptions that affect amounts in the financial statements and
accompanying notes and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

     In November 1999, the Company issued ?225.0 million aggregate principal
amount of 10.50% notes due 2006 (the "New Senior Notes 2006") and ?275.0 million
aggregate principal amount of 11% notes due 2009 (the "New Senior Notes 2009, "
and together, the "New Senior Notes"). The New Senior Notes are general
unsecured obligations of the Company. The New Senior Notes 2009 are redeemable
in whole or in part, at our option at any time on or after December 1, 2004 at a
price ranging from 105.50% to 100.0% of the principal amount. A portion of the
New Senior Notes 2009 notes are also redeemable at any time prior to or from
time to time prior to December 1, 2002 at a redemption price equal to 111% of
the principal amount of the notes redeemed, plus accrued and unpaid interest,
with the proceeds of public equity offerings or strategic equity investments of
at least $75.0 million, provided that following such redemption at least
two-thirds of the principal amount of such notes remain outstanding. The New
Senior Notes 2006 notes are not so redeemable.

     In January 1999, the Company issued aggregate principal amount $200 million
of senior notes due January 15, 2009 (the "Senior Notes due 2009") and ?85
million (approximately $100 million) of senior notes due January 15, 2006 (the
"Senior Notes due 2006"). The Senior Notes due 2006 and the Senior Notes due
2009 are general unsecured obligations of the Company, with interest payable
semiannually at a rate of 10.375%. The Company may redeem the Senior Notes due
2009 in whole or in part, any time on or after January 15, 2004 at specific
redemption prices. The Company may redeem the Senior Notes due 2006, in whole or
in part, any time on or after January 15, 2003 at specific redemption prices.
The Company may also redeem the Senior Notes due 2009 and the Senior Notes due
2006 at a price equal to 110.375% of the principal amounts prior to January 15,
2002 with net cash proceeds of a public equity offering with gross proceeds of
at least $75 million or in certain other circumstances specified in the
indentures for the Senior Notes due 2009 and the Senior Notes due 2006 provided,
however that at least two-thirds of the principal amount of the Senior Notes due
2009 and the Senior Notes due 2006 originally issued remain outstanding after
each such redemption.

     In August 1997, the Company issued aggregate principal amount $265.0
million of senior notes due August 15, 2007 (the "Senior Notes due 2007"). The
Senior Notes due 2007 are general unsecured obligations of the Company, with
interest payable semiannually at a rate of 11.5%. Approximately $56.6 million of
the net proceeds of the offering was placed in escrow for the first four
semiannual interest payments commencing on February 15, 1998. The Company may
redeem the Senior Notes due 2007, in whole or in part, any time on or after
August 15, 2002 at specific redemption prices. The Company may also redeem the
Senior Notes due 2007 at a price equal to 111.5% of the principal amount prior
to August 15, 2000 with net cash proceeds of a public equity offering with gross
proceeds of at least $75.0 million or in certain other circumstances specified
in the indenture for the Senior Notes due 2007, provided, however, that at least
two-thirds of the principal amount of the Senior Notes due 2007 originally
issued remain outstanding after each such redemption.

     In August 1999, the Company entered into a term-sheet, with a bank, for a
$35 million Credit Facility, which enabled the Company to issue performance or
payment guarantees in the ordinary course of business. During the first quarter
of 2000, the Company expects that it will finalize this credit facility which
will then allow the Company to draw down cash against this facility.

     Aggregate maturities of long-term debt, as of December 31, 1999, are as
follows: 2000 -- $0.07 million, 2001 -- $0.06 million, 2002 -- $0.05 million,
2003 -- $0.05 million, 2004 -- $0.07 million, and $1,057.7 million thereafter.

NOTE 4: EMPLOYEE BENEFITS

     The Company established a defined benefit pension plan in 1995 that covers
substantially all of its employees upon twenty-five years of age and at least
one year of service. The benefits are based on years of service and the
employee's compensation. The Company has entered into an arrangement, an
investment contract, with an insurance company for the provision of a group
insurance policy ("the Policy"). Premium payments for the Policy are partly paid
by the employee, based on specified terms that reflect the employee's annual
salary, with the remaining premium paid by the employer. The Company's pension
costs for 1999, 1998 and 1997 were $1.8 million, $1.0 million and $0.7 million,
respectively.

     The Company applies the provisions of APB No. 25 in accounting for its
stock option incentive plans. The effect of applying SFAS No. 123 on the net
loss as reported is not representative of the effects on reported net loss for
future years due to the vesting period of the stock options and the fair value
of additional stock options in future years. Had compensation expense been
determined in accordance with the methodology of SFAS No. 123, the Company's net
income (loss) for the years ended December 31, 1999 and 1998, respectively would
have been approximately $28.9 million and $(49.1) million.

     The Company maintains the Stock Option Plan, with the maximum number of
shares of common stock available for grant under the Stock Option Plan of
24,760. All options granted under the Stock Option Plan were at exercise prices
that were at least equal to the fair market value of common stock at the date of
grant. Generally, all options granted under the Stock Option Plan vest over a
three-year period from the date of grant and expire ten years from the date of
grant.

     Additional information with respect to stock option activity is summarized
as follows:

     In June 1998, certain employees of the Company received an aggregated
restricted stock award of 60,000 shares of GTS common stock, which vest pro rata
over two years. The Company incurred non-cash charges of $0.7 million and $0.4
million in 1999 and 1998, respectively, based on the market price of the GTS
common stock of $21.75 at date of grant.

     During 1998, the Company established the Ebone Value Creation Plan (the
"Ebone Plan"), in order to allow the employees of Ebone to benefit from any
increase in the fair value of Ebone. Under terms of the Ebone Plan, an aggregate
15,000 units, with a maximum value of $1,000 per unit based on the fair value of
Ebone at designated periods as determined by a third-party investment bank, may
be allocated to the employees over the term of the plan. As of December 31,
1998, 1,375 units had been allocated to the employees. In connection with
purchase of the 25% minority interest in Ebone in May 1999, (see Note 10,
"Acquisition") the Ebone Plan was revised (the "New Ebone Plan"). Under the New
Ebone Plan, 7,300 units, with a value of $750 per unit, were allocated to the
employees. No additional units will be allocated. Unit holders received a
payment of 20% of the agreed value on September 30, 1999. The remaining payments
will be made on September 30, 2001 (40%) and September 30, 2002 (40%). Payments
are conditioned on the unit holders remaining in employment at the relevant
dates. The Company recognized a compensation charge of $1.5 million and $1.0
million for the years ended December 31, 1999 and 1998, respectively, in
connection with the Ebone Plan.

MAJOR CUSTOMERS

    In 1998, the Company had two major customers, representing $9.5 million and
$9.3 million or 11.1% and 10.9% of revenue, respectively. In 1997, the Company
had two major customers, representing $1.8 million and $1.2 million or 34.2% and
21.7% of revenue, respectively. There were no major customers in 1999.

OTHER MATTERS

     In the ordinary course of business, the Company may be party to various
legal and tax proceedings, and subject to claims, certain of which relate to the
regulatory environments in which the Company currently operates or intends to
operate. In the opinion of management, the Company's liability, if any, in all
pending litigation, or other legal proceeding or other matter other than what is
discussed above, will not have a material effect upon the financial condition,
results of operations or liquidity of the Company.

NOTE 8: RELATED PARTY TRANSACTIONS

     On October 15, 1999, GTS entered into an exchange agreement with all of the
minority interest holders of the Company's common shares and grantees of stock
options to purchase common shares of the Company that provides for the
acquisition by GTS of their equity interest in the Company. Specifically, the
agreement provides that GTS will acquire the respective minority interest
holders' common shares in the Company that have been held by them for a period
greater than six months based on the current fair market value of the Company on
the date of the exchange, as determined by a globally-recognized investment
banking firm that is mutually acceptable to the parties to the agreement. The
agreement also provides that GTS would issue its common shares to the Company's
minority interest holders based on the fair market value of GTS common shares on
the date of the exchange.

     Pursuant to this agreement and effective October 15, 1999, GTS exchanged
5,985,930 of its common shares for 6,565 of the Company's common shares. This
transaction resulted in aggregate purchase consideration of approximately $134.2
million and as a result the Company reflected incremental goodwill of
approximately $133.0 million.

     Further, minority interest holders of the Company have additional
beneficial ownership rights in the Company's common shares and stock options to
purchase common shares, totaling 3,600 common shares. As stated previously, GTS
has agreed to acquire these Company common shares in the future; however, future
acquisitions will be based on future fair market values of the Company and GTS.

     In January 1999, a subsidiary of GTS entered into an agreement with FLAG
Telecom, to establish a 50/50 joint venture, called FLAG Atlantic Limited, to
build and operate the world's first transatlantic dual cable system designed to
carry voice, high-speed data and video traffic. The joint venture has announced
that this high-capacity fiber optic link between Europe and the United States,
which is called FLAG Atlantic-1 ("FA-1"), is expected to begin offering
unprotected services in the first quarter of 2001 and fully protected services
in the second quarter of 2001. On October 13, 1999, GTS announced that it has
committed to purchase one dedicated fiber pair on FA-1. In December 1999, the
Company purchased the dedicated fiber pair from GTS for $250 million. In
connection with this purchase in December 1999, GTS made an equity contribution
of $50 million to the Company. These transactions have been recorded on a net
basis.

     In June 1999, GTS Carrier Services, Inc. acquired SNCB/NMBS' ownership
interest of 13,610 common shares in the Company for approximately $101.3
million. In October 1998, GTS Carrier Services, Inc. acquired AB Swed Carrier's
ownership interest of 6,551 common shares in the Company for approximately $5.8
million. In connection with these purchases, GTS Carriers Services, Inc. paid
approximately $10.0 million to a company that was affiliated with a board member
for negotiating with AB Swed Carrier and SNCB/NMBS on behalf of GTS Carrier
Services, Inc. to purchase their respective ownership interest in the Company.

     Included in revenue for the years ended December 31, 1999, 1998 and 1997,
respectively is $28.2 million, $0.9 million and $0.3 million of revenue from GTS
affiliates.

NOTE 9: FOREIGN CURRENCY TRANSACTIONS

     On April 19, 1998, the Company entered into a foreign currency swap
transaction agreement (the "Swap") with Rabobank International ("Rabo") in order
to minimize the foreign currency exposure resulting from the issuance in August
1997 of $265.0 million aggregate principal amount 11.5% Senior Notes due 2007
(the "Senior Notes"). The Company remeasured the value of the swap as of
December 31, 1999 and 1998 and the resulting change in value of $39.5 million
and $27.8 million, respectively, has been recorded as a non-current liability on
the balance sheet and recognized as a foreign currency item in the statement of
operations. The foreign currency effect recognized on marking the Swap to its
remeasured value for the years ended December 31, 1999 and 1998 was offset in
the statement of operations by the revaluation of the Senior Notes.

NOTE 10: ACQUISITION

     On June 24, 1998, the Company completed the acquisition for approximately
$99.5 million of a 75% interest in Ebone. The Company funded the acquisition
with proceeds of a short-term bank loan, which has been repaid. Ebone is a Tier
1 Internet backbone provider, principally serving as a carriers' carrier for
European Internet service providers. As part of the transaction, Ebone
purchased, under a transmission capacity agreement, long-term capacity rights on
the Network valued at approximately $99.5 million. In addition to the majority
interest held by the Company, Ebone's ownership structure included many of
Ebone's existing customers, which owned the balance of the shares through an
association (the "Association"). The members of the Association were offered the
right to buy shares of Ebone in the third quarter of 1998; however, the
Company's ownership interest in Ebone was not reduced as a result of the
acceptances of this offer.

     The acquisition was accounted for using the purchase method of accounting.
The excess purchase price over the fair value of assets acquired of $19.7
million was allocated to goodwill. The results of Ebone have been included in
the accompanying consolidated financial statements from the date of acquisition.

     On May 25, 1999, the Company purchased the remaining 25% minority interest
in Ebone from the Association for a purchase price of $35 million. The purchase
price was comprised of cash of $15 million and the issuance to the Association
of capacity rights on the Network valued at $20 million (the "Rights"). Rights
may be applied by members of the Association, in lieu of cash, to the payment of
future invoices related to services provided by the Company or Ebone on
contracts for services entered into through May 31, 2003. The Association
assigned these Rights among its members by October 1, 1999 and once assigned,
the Rights are non-transferable. The excess of the purchase price over the fair
value of the assets acquired of $9.2 million was allocated to goodwill.

BOARD OF SUPERVISORY DIRECTORS

     Our general affairs and business and the executive board which manages the
company (the "Board of Managing Directors") (Directie) are supervised by a board
appointed by the general meeting of shareholders (the "Board of Supervisory
Directors") (Raad van Commissarissen).

     Our Articles of Association (the "Articles of Association") provide for at
least four and no more than ten supervisory directors who must be natural
persons ("Supervisory Directors") to serve on the Board of Supervisory
Directors. Under the law of the Netherlands, a member of the Board of
Supervisory Directors of a company cannot be a member of the Board of Managing
Directors of the same company. The members of the Board of Supervisory Directors
are appointed by the general meeting of shareholders. The Board of Supervisory
Directors elects a chairman from among its members. See "Certain Relationships
and Related Transactions." Under the Shareholders Agreement, resolutions of the
Board of Supervisory Directors require the approval of a majority of the
Supervisory Directors present. The quorum for a valid meeting is a majority of
the members of the Supervisory Board with a minimum of four members. The Board
of Supervisory Directors meets four times a year and also upon the request of
its chairman or the Board of Managing Directors. Pursuant to the Articles of
Association, Supervisory Directors may be suspended or dismissed by the general
meeting of shareholders. The remuneration or compensation of the Supervisory
Directors is determined by the general meeting of shareholders.

     While the Board of Managing Directors is the executive body of the company
and is responsible for managing its affairs and representing the company in its
dealings with third parties, the primary responsibility of the Board of
Supervisory Directors is to supervise the policies enacted by the Board of
Managing Directors and the general course of our affairs. The Board of
Supervisory Directors advises the Board of Managing Directors. In the
fulfilLment of their duties, members of the Board of Supervisory Directors are
required to act in our best interests.

KEY EMPLOYEE STOCK OPTION PLAN OF GLOBAL TELESYSTEMS EUROPE B.V.

     We have adopted the Key Employee Stock Option Plan of GTS Europe (the "New
Plan"). Under the New Plan certain employees of GTS Europe will be granted stock
options to purchase its common stock. Subject to adjustment in the event of
certain changes in capitalization, a maximum of 24,760 shares of GTS Europe
common stock are authorized for grant under the New Plan.

     The New Plan is administered by a committee composed of two members of the
Board of Supervising Directors which will have broad discretion to determine who
shall receive awards under the New Plan, the terms of such awards and interpret
the New Plan. The New Plan shall become effective upon its adoption by the Board
of Supervising Directors and shall continue in effect until 2004, unless
terminated earlier by the Board of Supervising Directors.

     Each stock option granted under the New Plan shall have a term of ten
years, except those granted in 1997 reflected in the table above. The exercise
price of each such stock option will be determined at the time of grant. In
addition the stock options granted under the New Plan will become exercisable at
such times and under such conditions as determined by the committee.

     The Board of Supervising Directors may amend or terminate the New Plan at
any time, provided that the rights of participants are not impaired.

PENSION PLAN

     In 1995, we established a defined benefit pension plan (the "Pension Plan")
that covers substantially all of its employees that are at least twenty-five
years of age and have at least one year of service. The benefits are based on
years of service and the employee's compensation at retirement. Mr. Shearing
participates in the Pension Plan. Each participant in the Pension Plan will
receive a lump sum at retirement equal to 450% of final annual salary up to a
specified ceiling which changes every year (in 1998 the ceiling was BF1,352,000)
plus 910% of the excess multiplied by the years of service divided by 35. The
maximum years of service taken into account under the formula is 35. The normal
retirement age is 60. We have entered into an agreement with an insurance
company for the provision of a group insurance policy (the "Policy"). Premium
payments for the Policy are partly paid by the employee based on specified terms
that consider the employee's annual salary, with the remaining premium paid by
us. Premiums are intended to provide not only for benefits attributed to service
to date but also for those expected to be earned in the future. (See Note 4 to
the Notes to Consolidated Financial Statements). Upon termination of employment
prior to retirement age, employer contributions cease and the participant may
decide to receive the cash surrender value of the policy, to continue paying
premiums or cease paying premiums but in either case maintaining the policy
which is paid out according to its terms.

The above pension benefits are based on the following formula: (260% S1 + 910%
S2) x N/35

                                 S  =  annual salary

                                 S1 =  S up to the "ceiling"

                                 S2 =  S above the "ceiling"

                                 N  =  years of service up to a maximum of 35

For purposes of this calculation, the "ceiling" is U.S. $42,200.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

PURCHASE OF SHARES BY GTS CARRIER SERVICES

     In connection with its purchases of AB Swed Carrier's and SNCB/NMBS's
minority common share interests in GTS Europe in December 1998 and June 1999,
respectively, GTS Carrier Services paid approximately $10.0 million to a company
that is affiliated with a member of the Supervisory Board of GTS Europe for
negotiating with AB Swed Carrier and SNCB/NMBS on behalf of GTS Carrier Services
to purchase their respective ownership interests in GTS Europe.

PURCHASE OF FIBER

     In January 1999, a subsidiary of GTS entered into an agreement with FLAG
Telecom, to establish a 50/50 joint venture to build and operate the world's
first transatlantic dual cable system designed to carry voice, high-speed data
and video traffic at data transmission rates of up to 2.4 terabits per second.
The joint venture has announced that this high-capacity fiber optic link between
Europe and the United States, which is called FLAG Atlantic-1, is expected to
begin offering unprotected services in the first quarter of 2001 and fully
protected services in the second quarter of 2001. On October 13, 1999, GTS
announced that it has committed to purchase one dedicated fiber pair on FLAG
Atlantic-1. In December 1999, the Company purchased the dedicated fiber pair
from GTS for $200 million.
